Acoustic impulse generator

专利汇可以提供Acoustic impulse generator专利检索，专利查询，专利分析的服务。并且Apparatus for generating high energy impulses or acoustic transients when submerged under water is described. A piston is moved against the external water pressure head to an outward position by rollers which are pivotally mounted on latch arms and which engage a cam surface at the rear of the piston. When the piston reaches the outward position, the rollers are pivoted by a trip bar which travels with the rollers to the outward position. The rollers then ride over the cam surface; thus releasing the piston to travel over a return stroke to a rearwardly disposed anvil. The energy of the water head is converted to kinetic energy of a moving column of water as the piston is accelerated rearwardly on the return stroke. The moving column of fluid is suddenly decelerated when the piston impacts the anvil; thus, converting the kinetic energy of the moving fluid column into an acoustic impulse or transient in the form of a shock wave which is radiated outwardly into the surrounding water. A shock absorber and dampers are associated with the anvil to bring the piston gently to rest after impact.，下面是Acoustic impulse generator专利的具体信息内容。
1. For use in an acoustic impulse generator adapted to be submerged in which a piston is mounted for reciprocation in a housing in which the pressure is adapted to be lower than the pressure of the medium in which it is submerged, a mechanism for moving said piston against said pressure of said medium and then releasing said piston to generate said acoustic impulse which comprises driving means in said housing movable toward and away from said piston for moving said piston to execute a forward stroke against the pressure of said medium, roller means pivotally mounted on said driving means for engaging said piston, said piston having a surface disposed for engagement with said roller means during said forward stroke, and release means operative when said driving means moves a predetermined distance along its forward stroke for pivoting said rollerss so that they move off said piston surface and release said piston to execute a return stroke under the pressure of said medium whereby to generate the acoustic impulse.
2. The invention as set forth in claim 1 wherein said piston surface includes first and second adjacent regions, and second region being a cam surface, said roller means mounted to move from a latch position on said first region to a trip position on said second region when pivoted by said release means whereby said roller means cams over said second region to release said piston for its said return stroke.
3. The invention as set forth in claim 2 wherein said first region is of generally concave shape in which said roller means is retained while in its said latch position, and said second region is of generally convex shape over which said roller means cams when pivoted to its said trip position.
4. The invention as set forth in claim 3 wherein said piston has an internal opening into a rear end thereof which faces said housing, said surface being located in the wall of said opening with said first region closer to said rear end then said second region.
5. The invention as set forth in claim 1 wherein said driving means include a member actuable in a forward direction towards said piston, said roller means including a link having a roller mounted near one end thereof, means for pivotally mounting said link on said member, and trip means movably mounted in said member for biasing said link to pivot to a latch position to bring said roller into driving engagement with said piston.
6. The invention as set forth in claim 5 wherein said trip means includes a bar movably mounted in said member for engagement with said link to pivot said link in one sense to said latch position and in an opposite sense to a trip position where said roller is released from said piston, and a spring disposed between said bar and said member for biasing said bar to pivot said link in said one sense.
7. The invention as set forth in claim 6 wherein said release means includes a member movably mounted on said driving means member, means coupling said release means member to said bar for movement therewith, and means for limiting the movement of said release means member when said driving means moves said predetermined distance in said forward direction such that said bar engages said link and pivots it in the opposite sense to said trip position.
8. The invention as set forth in claim 7 wherein said release means member includes a collar slidably mounted on said driving means member, rod means attached at one end thereof to said collar and extending longitudinally along said drive means member, and stop means engageable with said rod means near the opposite end thereof.
9. The invention as set forth in claim 8 wherein said stop means includes a bushing through which said rod means extend, the opposite end of said rod means being enlarged to stop the travel of said rod means in the forward direction to a distance about equal to the length of said rod means.
10. The invention as set forth in claim 9 wherein said driving means includes a hydraulic cylinder and said driving means member includes the piston of said cylinder, said bushing being stationarily mounted on said cylinder.
11. The invention as set forth in claim 1 wherein said roller means includes a pair of latch arms of L shape, said driving means includes an actuator having a drive member axially movable in said housing in a forward direction toward said piston and in a return direction away from said piston, said piston having an axial opening in the rear end thereof facing said housing which presents said roller engaging surface, said surface having a cam shape inwardly convex towaRd the axis of said piston, said cam shape surface having a center spaced from said piston rear end, said roller being in a latch position for driving said piston when disposed on the side of said cam surface between its said center and said piston rear end and in a trip position when disposed over said center toward the piston forward end, said driving means also including a latch carrier on which said latch arms are pivotally mounted, said latch carrier being attached to the forward end of said driven member, a trip bar slidably mounted in said latch carrier, said trip bar having a groove into which one end of each of said latch arms extend, a compression spring in said latch carrier biasing said trip bar in a forward direction to pivot said latch arms and bring said roller to said latch position, said release means including a trip carrier slidably mounted on said latch carrier, a pin extending from said trip carrier through said trip bar, and rods attached to said trip carrier and extending longitudinally rearwardly along said drive member, stop means for limiting the movement of said rods and said trip carrier in a forward direction so that said bar is moved in a rearward direction to pivot said latch arms and bring said roller to said trip position.
12. The invention as set forth in claim 1 wherein there is provided, in addition to said mechanism, means for arresting the movement of said piston at the end of its return stroke which comprises an anvil movably mounted in said housing against which said piston impacts when released, yieldable means for biasing said anvil in a forward direction towards an impact position, and damping means spaced rearwardly of said impact position for engaging and damping the motion of said piston during an interval after impact when said anvil is displaced rearwardly of said impact position.
13. The invention as set forth in claim 12 including a stop member for engaging said anvil and positioning it against the bias of said yieldable means at said impact position, said damping means including a pad of resilient material, said stop member being movably mounted in said housing with the forward side thereof against said housing and the rearward side thereof against said pad, said forward side being spaced rearwardly of said impact position to form a gap between said stop member and said impact position.
14. The invention as set forth in claim 13 wherein said yieldable means is a shock absorber attached to said anvil.
