Description

Technical Field

[0001] This application relates to the technical field of underwater unexploded ordnance (UXO) sympathetic detonation tests, and particularly to a safety charge placement device for underwater UXO sympathetic detonation tests. Background Art

[0002] According to the nautical chart data of our country, there are still many historical minefields in the coastal waters of our country. It is suspected that there are naval mines left over from World War II. Most of these naval mines are bottom mines, which are all placed on the seabed and covered with sediment of different thicknesses on the surface, but generally the thickness is not large. With the increasing development of offshore wind power construction, the scope of use of the sea area is getting larger and larger. In order to provide safety guarantees for the construction of offshore projects such as offshore wind farms, it is necessary to detect and dispose of underwater unexploded ordnance (UXO), eliminate potential safety hazards, and update nautical charts. However, before the formal disposal of explosives, it is very necessary to test the equipment and construction plan. In underwater UXO sympathetic detonation tests, usually, a UXO model is first set up, and then an explosive package is placed at a certain coordinate point on the UXO model, and then sympathetic detonation is carried out. Relevant test data is obtained through sensors on the UXO model.

[0003] In the prior art, when conducting sympathetic detonation tests, the conventional method is for divers to carry shaped charges (explosive packages) and dive underwater to place the shaped charges on the UXO model. By detonating the shaped charges, the sensors on the UXO model can obtain relevant test data. However, such a charge placement method is applicable to relatively shallow waters. For waters deeper than a certain depth (more than 20 meters), the underwater visibility is low, and there are situations such as large underwater flow velocities in some waters, making it very difficult for divers to maintain their own stability and place the shaped charges in the correct position. Therefore, there is an urgent need for a charge placement device that can improve the placement accuracy of shaped charges, reduce the possibility of lateral displacement of the shaped charges during the placement process due to lateral thrust from the water flow, and improve the operation safety of construction personnel. Summary of the Invention

[0004] In order to improve the placement accuracy of shaped charges, this application provides a safety charge placement device for underwater UXO sympathetic detonation tests.

[0005] The safety charge placement device for underwater UXO sympathetic detonation tests provided by this application adopts the following technical solutions: A safety charge - placing device for underwater UXO sympathetic detonation tests, comprising a mounting frame, a positioning rod and a dispenser. Among them, the mounting frame is arranged on a workboat, a guiding ring is provided on the mounting frame, the positioning rod is vertically arranged, and the positioning rod slidably penetrates through the guiding ring for extending into the seabed surface; the dispenser includes a sliding seat, a hanging post and a control member. The sliding seat is sleeved on the outer peripheral wall of the positioning rod, the hanging post is arranged on the sliding seat, the side wall of the shaped charge has a hanging ring, the hanging ring has a hanging hole, the hanging post is inserted into the hanging hole from bottom to top, and a slipping gap is formed between the hanging ring and the bottom wall of the shaped charge; the control member is arranged on the sliding seat for driving the sliding seat to move up and down.

[0006] By adopting the above - mentioned technical solution, during charge placement, move the workboat to position the guiding ring of the mounting frame at the actual position of the UXO model. Then, pass the positioning rod through the guiding ring and sink it to the seabed surface. Then, align the hanging hole of the hanging ring of the shaped charge with the hanging post and insert the hanging post into the hanging hole from bottom to top. Then, drive the sliding seat to move down along the positioning rod through the control member to guide the shaped charge to sink to the seabed surface; after the shaped charge sinks to the seabed surface, continue to lower the sliding seat. Since there is a slipping gap between the hanging ring and the bottom wall of the shaped charge, as the sliding seat continues to sink, the hanging post can automatically disengage from the hanging hole, realizing the placement of the shaped charge at the set position, greatly improving the placement accuracy of the shaped charge.

[0007] Optionally, the control member includes a control rod and a control rope. One end of the control rod is connected to the sliding seat, and the other end is connected to the control rope. The end of the control rope away from the control rod extends to the workboat for lifting the control rod; a camera is provided on the control rod.

[0008] By adopting the above - mentioned technical solution, the control rope is connected to the sliding seat through the control rod, enabling the operator on the workboat to control the lifting of the sliding seat; during the lowering process of the sliding seat, the whole process is monitored by the camera, facilitating the operator on the workboat to observe and handle, and improving the operation safety of the construction personnel.

[0009] Optionally, two swing bars are hinged to the side wall of the sliding seat. The hanging post includes two hanging parts, the two hanging parts are arranged corresponding to the two swing bars, and each hanging part is installed on the free end of the corresponding swing bar. When the free ends of the two swing bars are flipped to abut against each other, the two hanging parts are combined to form the hanging post; a flipping assembly for driving the two swing bars to flip is provided on the control rod.

[0010] By adopting the above technical solution, after the sliding seat imports the shaped charge into the seabed surface, the sliding seat continues to be driven downward for a certain distance to disengage the hanging column from the hanging hole, and then the flipping assembly forces the two swing bars to swing, so that the free ends of the two swing bars move away from each other, that is, the two hanging parts are forced to move away from each other, so that when the sliding seat is manipulated to lift, the two hanging parts can avoid the hanging ring of the shaped charge, improving the operation convenience of the overall structure.

[0011] Optionally, the flipping assembly includes a sliding bar, a pushing block and a driving member. The sliding bar is slidably mounted on the control rod, and one end of the sliding bar extends below the two swing bars and is connected to the pushing block; a tip is formed at the top of the pushing block. When the sliding bar is lifted, the tips of the pushing block respectively push the two swing bars and force the free ends of the two swing bars to move away from each other; the driving member is arranged on the control rod to drive the sliding bar to lift.

[0012] By adopting the above technical solution, after the sliding seat imports the shaped charge into the seabed surface, the sliding seat continues to be driven downward for a certain distance to disengage the two hanging parts from the hanging hole. At this time, the driving member forces the sliding bar to lift, driving the pushing block to lift. The pushing block forces the free ends of the two swing bars to move away from each other through the tip, so that the two hanging parts "open" to avoid the hanging ring of the shaped charge, reducing the possibility that the two hanging parts collide with the hanging ring when the sliding seat is lifted from the seabed surface, resulting in the shaped charge being deflected.

[0013] Optionally, the driving member includes a control seat, a docking block and a return spring. The control seat is slidably sleeved on the outer peripheral wall of the control rod, and the control rope is connected to the control seat; a first docking groove is formed in the side wall of the sliding bar, and a second docking groove is formed in the inner wall of the control seat. When the control seat moves downward relative to the control rod, the second docking groove can be displaced to communicate with the first docking groove; the docking block is slidably mounted in the first docking groove, and the return spring is arranged in the first docking groove. In the normal state, the return spring forces the docking block to be partially exposed from the first docking groove; the docking block has a guiding surface for the bottom wall of the control seat to abut against to force the docking block to move into the first docking groove.

[0014] By adopting the above technical solution, after the sliding seat imports the shaped charge into the seabed surface, continue to relax the control rope to move the sliding seat downward by a certain distance, so that the two hanging parts are disengaged from the hanging holes; after the two hanging parts are disengaged from the hanging holes, continue to lower the control rope so that the control seat can move downward relative to the control rod. When the bottom wall of the control seat abuts against the guiding surface of the docking block, the docking block is moved into the first docking groove under the action of the gravity of the control seat, so that the second docking groove of the control seat can move downward to communicate with the first docking groove. At this time, the docking block is inserted into the second docking groove under the action of the return spring, realizing the "docking" between the control seat and the sliding bar. Then, pull the control rope to drive the control seat to move upward, and the sliding bar can be driven to move upward synchronously, so as to force the two hanging parts to "open", improving the operation convenience of the overall structure.

[0015] Optionally, a first limiting block is provided at the upper end of the control rod. When the control seat is lifted, the control seat abuts against the first limiting block and drives the control rod to lift through the first limiting block. A second limiting block is provided on the side wall of the control rod. When the control seat moves downward relative to the control rod and abuts against the second limiting block, the first docking groove communicates with the second docking groove; a limiting rod is provided at the bottom of the sliding seat. When the hanging post is disengaged from the hanging hole, the lower end of the limiting rod abuts against the seabed surface.

[0016] By adopting the above technical solution, the setting of the limiting rod makes it impossible for the sliding seat to continue to move downward after the two hanging parts are disengaged from the hanging holes. Therefore, when the control rope is continuously lowered, the control seat can move downward relative to the control rod, so that the control seat can "dock" with the sliding bar. The setting of the first limiting block makes it possible that when the control seat is lifted and forces the free ends of the two swing bars to move away from each other, the control seat can abut against the first limiting block and drive the control rod to move upward through the first limiting block to drive the sliding seat to lift.

[0017] Optionally, the second docking groove penetrates through the top wall of the control seat, and an unlocking rod is provided at the bottom of the mounting frame. When the control seat is lifted and forces the first limiting block to abut against the mounting frame, the unlocking rod is inserted into the second docking groove, and the docking block is forced to move into the first docking groove through the guiding surface.

[0018] By adopting the above technical solution, after the control seat drives the sliding seat to lift off the sea level, when the first limiting block is lifted to abut against the bottom wall of the mounting frame, at this time, the unlocking rod can be inserted into the second docking groove, and the docking block is pushed through the guiding surface of the docking block, so that the docking block moves into the first docking groove. The sliding bar moves downward under its own gravity, so that the docking block can be disengaged from the control seat, that is, the tip of the pushing block can be disengaged from the two swing bars, realizing that the free ends of the two swing bars can swing back to the abutting state again, so that the two hanging parts can be combined again to form a hanging post for installing the next shaped charge, improving the operation convenience of the overall structure.

[0019] Optionally, a bracket is provided on the workboat, and a winding roller is rotatably mounted on the bracket. One end of the control rope away from the control rod is wound around the outer peripheral wall of the winding roller; the bracket is provided with a rotating assembly for driving the winding roller to rotate.

[0020] By adopting the above technical solution, through the arrangement of the winding roller and the rotating assembly, the control rope is wound and unwound to realize the lifting of the sliding seat.

[0021] Optionally, the rotating assembly includes a rotating disc, a rotating cam and a rotating member. The rotating disc is coaxially arranged on the outer peripheral wall of one end of the winding roller. The rotating cam is provided with a rotating shaft, and the rotating shaft is rotatably mounted on the bracket; a driving column is provided on the surface of the rotating cam, and the driving column is eccentrically arranged with respect to the rotating shaft. A strip-shaped groove for the driving column to turn into is formed on the surface of the rotating disc, and a plurality of strip-shaped grooves are arranged at intervals around the central axis of the rotating disc. Both ends of each strip-shaped groove extend along the radial direction of the rotating disc. When the rotating cam rotates, the rotating cam drives the rotating disc to rotate intermittently through the driving column; the rotating member is arranged on the bracket to drive the rotating cam to rotate.

[0022] By adopting the above technical solution, the rotating member drives the rotating cam to rotate. The rotating cam drives the driving column to perform "revolution" around the central axis of the rotating shaft, so that the driving column can intermittently turn into or out of the strip-shaped groove. When the rotating cam rotates continuously, the rotating disc can be driven to rotate intermittently, thereby controlling the lifting of the sliding seat and reducing the possibility that the hanging column disengages from the hanging hole when the sliding seat sinks to the seabed surface due to the too fast downward movement speed of the sliding seat.

[0023] Optionally, a rotation prevention column is provided on the surface of the rotating cam. The outer peripheral wall of the rotation prevention column has a first rotation prevention surface, and a second rotation prevention surface is provided on the outer peripheral wall of the rotating disc. The number of the second rotation prevention surfaces corresponds to the number of the strip-shaped grooves. All the second rotation prevention surfaces and all the strip-shaped grooves are arranged staggeredly around the central axis of the rotating disc; when the driving column turns out of the strip-shaped groove, the first rotation prevention surface abuts against the second rotation prevention surface to limit the free rotation of the rotating disc; when the driving column turns into the strip-shaped groove, the first rotation prevention surface disengages from the second rotation prevention surface, and an avoidance notch is formed on the outer peripheral wall of the rotation prevention column.

[0024] By adopting the above technical solution, when the driving column turns into the strip-shaped groove, the avoidance notch is used to avoid the outer wall of the rotating disc at this time, so that the rotating cam can drive the rotating disc to rotate a certain angle through the cooperation of the driving column and the strip-shaped groove. As the rotating cam continues to rotate, when the driving column turns out of the strip-shaped groove, the first rotation prevention surface and the second rotation prevention surface abut against each other at this time, thereby restricting the free rotation of the rotating disc, that is, restricting the free rotation of the winding roller, reducing the possibility that the winding roller rotates freely and causes the control rope to be rapidly lowered, and improving the stability of the overall structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the settings of the positioning rod and the dispenser, when applying medicine, move the working boat to position the guiding ring of the mounting frame at the actual position of the UXO model, then pass the positioning rod through the guiding ring and sink it to the seabed surface. Then align the hanging hole of the shaped charge package hanging ring with the hanging post, insert the hanging post into the hanging hole from bottom to top. Next, drive the sliding seat to move downward along the positioning rod through the control member to guide the shaped charge package to sink to the seabed surface. After the shaped charge package sinks to the seabed surface, continue to lower the sliding seat. Since there is a slipping gap between the hanging ring and the bottom wall of the shaped charge package, as the sliding seat continues to sink, the hanging post can automatically disengage from the hanging hole, realizing the placement of the shaped charge package at the set position, greatly improving the placement accuracy of the shaped charge package. 2. Through the setting of the flipping assembly, after the sliding seat guides the shaped charge package to the seabed surface, continue to drive the sliding seat to move downward a certain distance to disengage the two hanging parts from the hanging hole. At this time, force the sliding bar to lift through the driving member, drive the pushing block to lift, and the pushing block forces the free ends of the two swinging bars to move away from each other through the tip, so that the two hanging parts "open" to avoid the hanging ring of the shaped charge package, reducing the possibility that the two hanging parts collide with the hanging ring when the sliding seat lifts off the seabed surface and causing the shaped charge package to deflect. 3. Through the settings of the first anti-rotation surface and the second anti-rotation surface, when the driving column turns into the strip-shaped groove, the avoidance notch is used to avoid the outer wall of the rotating disc at this time, so that the rotating cam can drive the rotating disc to rotate a certain angle through the cooperation of the driving column and the strip-shaped groove. As the rotating cam continues to rotate, when the driving column turns out of the strip-shaped groove, the first anti-rotation surface and the second anti-rotation surface abut against each other at this time, thus restricting the free rotation of the rotating disc, that is, restricting the free rotation of the winding and unwinding roller, reducing the possibility that the winding and unwinding roller rotates freely and causes the control rope to be rapidly lowered, and improving the stability of the overall structure.

Detailed implementation manners

[0028] The following Figures 1 - 10 further elaborates on this application in detail. Embodiment 1

[0029] The embodiment of the present application discloses a safety charge-placement device for underwater UXO sympathetic detonation tests.

[0030] Referring to Figure 1 , a safety charge-placement device for underwater UXO sympathetic detonation tests includes a mounting frame 1, a positioning rod 11, and a dispenser. In this embodiment, the mounting frame 1 is used to be installed on the gunwale of a working ship. Two guide rings 12 are fixedly installed on the mounting frame 1, and the two guide rings 12 are arranged at intervals in the height direction; the positioning rod 11 is arranged vertically, and the positioning rod 11 slidably penetrates through the two guide rings 12 for extending into the seabed surface 9.

[0031] It should be noted that in this embodiment, the positioning rod 11 can be formed by splicing multiple rod bodies into a positioning rod 11 of a certain length. The adjacent two rod bodies can be spliced in a threaded connection form (not shown in the figure). A lifting hole 111 is provided at the upper end of the positioning rod 11. The lifting hole 111 is used to dock with a lifting device (such as a crane) to drive the positioning rod 11 to extend into or lift off the seabed surface 9.

[0032] Referring to Figure 1 、 Figure 2 、 Figure 3 , the placer includes a sliding seat 2, a hanging column 3 and a control member. The sliding seat 2 is sleeved on the outer peripheral wall of the positioning rod 11. In this embodiment, the sliding seat 2 includes a mounting portion 23, a movable portion 24 and a connecting screw 25. One end of the mounting portion 23 and one end of the movable portion 24 are hinged to each other. For the convenience of description, the end of the mounting portion 23 away from the hinge is defined as the free end of the mounting portion 23, and the end of the movable portion 24 away from the hinge is defined as the free end of the movable portion 24. One end of the connecting screw 25 is hinged to the free end of the mounting portion 23. A connecting groove for the connecting screw 25 to be inserted into is provided at the free end of the movable portion 24. A connecting nut 26 is threadedly sleeved on the end of the connecting screw 25 away from the mounting portion 23. When the connecting nut 26 locks the connecting screw 25, a through channel 27 for the positioning rod 11 to pass through is formed by enclosing between the mounting portion 23 and the movable portion 24.

[0033] A connecting strip 28 is fixedly installed on the side wall of the mounting portion 23. The hanging column 3 is cylindrical. The lower end surface of the hanging column 3 is fixedly installed on the top wall of the connecting strip 28. A hanging ring 81 is fixedly installed on the side wall of the shaped charge 8. The hanging ring 81 is annular and forms a hanging hole 811. The hanging column 3 is inserted into the hanging hole 811 from bottom to top. A slipping gap 82 is formed by spacing between the hanging ring 81 and the bottom wall of the shaped charge 8. The shaped charge 8 is connected with a detonator initiation wire 83.

[0034] Referring to Figure 1 、 Figure 3 , the control member is arranged on the sliding seat 2 to drive the sliding seat 2 to lift. The control member includes a control rod 4 and a control rope 41. The control rod 4 is arranged vertically. The lower end surface of the control rod 4 is fixedly installed on the mounting portion 23. The upper end of the control rod 4 is connected with the control rope 41. The end of the control rope 41 away from the control rod 4 extends to the workboat to lift the control rod 4. A camera 42 is fixedly installed on the outer peripheral wall of the control rod 4. The camera 42 faces downward to monitor the placement condition of the shaped charge 8.

[0035] The implementation principle of Example 1 of the present application is as follows: when deploying the charges, the work boat is moved to position the guide ring 12 of the mounting frame 1 to the actual position of the UXO model, and then the positioning rod 11 is passed through the guide ring 12 and sunk to the seabed surface 9, and then the hanging ring 81 of the energy-gathering charge 8 is hung on the hanging column 3, and the hanging column 3 is inserted into the hanging hole 811 from bottom to top, and then the sliding seat 2 is controlled by the control rope 41 to move downward along the length direction of the positioning rod 11 to guide the energy-gathering charge 8 to sink to the seabed surface 9.

[0036] After the shaped charge 8 sinks to the seabed 9, the sliding seat 2 continues to be lowered. Since there is a slip gap 82 between the hanging ring 81 and the bottom wall of the shaped charge 8, as the sliding seat 2 continues to sink, the hanging column 3 can automatically detach from the hanging hole 811, so that the shaped charge 8 can be placed at the set position, which greatly improves the placement accuracy of the shaped charge 8. After the hanging column 3 detaches from the hanging hole 811, the operator pulls the control rope 41 on the workboat to make the control rod 4 slightly rotate around the positioning rod 11 to make the hanging column 3 avoid the hanging ring 81 of the shaped charge 8, and then the sliding seat 2 can be lifted to the water surface through the control rope 41 for the next displacement release. The whole process is monitored by the camera 42, and the operator observes and handles on the workboat, which improves the convenience of operation of the overall structure. Example 2

[0037] The embodiment of the present application discloses a safe explosive deployment device for underwater UXO sympathetic explosion test.

[0038] The difference between the safe charge distribution device for underwater UXO sympathetic explosion test disclosed in the embodiment of the present application and the embodiment 1 is that: Reference Figure 4 , Figure 5 In this embodiment, the side wall of the mounting portion 23 of the sliding seat 2 is hinged with two swing bars 21, and the two swing bars 21 are arranged side by side. The rotation center axis of the swing bar 21 is parallel to the length direction of the positioning rod 11. For the convenience of description, the end of the swing bar 21 away from the mounting portion 23 is defined as the free end of the swing bar 21 below; in this embodiment, the hanging column 3 includes two hanging portions 31, and the two hanging portions 31 are arranged corresponding to the two swing bars 21. Each hanging portion 31 is installed on the free end of the corresponding swing bar 21. When the free ends of the two swing bars 21 are flipped to abut against each other, the two hanging portions 31 are combined to form the above-mentioned hanging column 3.

[0039] In this embodiment, the cross-sectional shape of the control rod 4 is set to be rectangular (i.e., the control rod 4 is a square rod structure), and the control rod 4 is provided with a flipping assembly 5 for driving the two swinging bars 21 to flip; the flipping assembly 5 includes a sliding bar 51, a pushing block 52 and a driving member. A sliding groove 45 is formed in the side wall of the control rod 4 away from the positioning rod 11, and both ends of the sliding groove 45 extend along the length direction of the control rod 4. The sliding bar 51 is slidably installed in the sliding groove 45 of the control rod 4 so as to be able to slide along the height direction.

[0040] Refer to Figure 4 , Figure 5 , Figure 6 , the lower end of the sliding bar 51 passes through the control rod 4 and extends below the two swinging bars 21. The pushing block 52 is fixedly installed at the lower end of the sliding bar 51, and a tip 521 is formed at the top of the pushing block 52. The bottom walls of the two swinging bars 21 both have guiding surfaces 211 for abutting against the tip 521 of the pushing block 52. When the sliding bar 51 is lifted, the sliding bar 51 drives the tip 521 of the pushing block 52 to push the guiding surfaces 211 of the two swinging bars 21 respectively, and forces the free ends of the two swinging bars 21 to move away from each other; designed in this way, the two hanging parts 31 can be "opened" to avoid the hanging ring 81.

[0041] A compression spring 512 is installed between the sliding bar 51 and the mounting part 23. One end of the compression spring 512 is fixedly connected to the sliding bar 51, and the other end is fixedly connected to the bottom wall of the mounting part 23. Under normal conditions, the compression spring 512 forces the tip 521 of the pushing block 52 to disengage from between the two swinging bars 21 (i.e., the compression spring 512 forces the pushing block 52 to move down below the two swinging bars 21).

[0042] Refer to Figure 5 , Figure 7 , the driving member is arranged on the control rod 4 for driving the sliding bar 51 to lift. In this embodiment, the driving member includes a control seat 53, a docking block 54 and a return spring 55. The control seat 53 is slidably sleeved on the outer peripheral wall of the control rod 4. A first limiting block 43 is fixedly installed at the upper end of the control rod 4. One end of the control rope 41 passes through the first limiting block 43 and is fixedly connected to the top wall of the control seat 53. When the control seat 53 is lifted, the control seat 53 abuts against the first limiting block 43 and drives the control rod 4 to lift through the first limiting block 43.

[0043] The side wall of the sliding bar 51 is provided with a first docking groove 511, the inner wall of the control seat 53 is provided with a second docking groove 531, and a second limiting block 44 is fixedly installed on the side wall of the control rod 4. When the control seat 53 moves downward relative to the control rod 4 and abuts against the second limiting block 44, the first docking groove 511 communicates with the second docking groove 531. The docking block 54 is slidably installed in the first docking groove 511. One end of the return spring 55 is fixedly connected to the inner wall of the first docking groove 511, and the other end is fixedly connected to the docking block 54. Under normal conditions, the return spring 55 forces a part of the docking block 54 to be exposed outside the first docking groove 511. The docking block 54 has a guiding surface 541. When the control seat 53 moves downward relative to the control rod 4, the bottom wall of the control seat 53 forces the docking block 54 to move into the first docking groove 511 through the guiding surface 541. A limiting rod 22 is fixed to the bottom wall of the movable part 24 of the sliding seat 2. When the hanging post 3 disengages from the hanging hole 811 and continues to drive the sliding seat 2 to move downward, the lower end of the limiting rod 22 abuts against the seabed surface 9.

[0044] Referring to Figure 7 , it should be noted that in this embodiment, the second docking groove 531 penetrates through the top wall of the control seat 53. An unlocking rod (not shown in the figure) is installed on the bottom wall of the mounting frame 1. The unlocking rod is vertically arranged. The upper end of the unlocking rod can be detachably installed on the mounting frame 1 in a bolt connection manner. When the control seat 53 is lifted and forces the first limiting block 43 to abut against the bottom wall of the mounting frame 1, the lower end of the unlocking rod is inserted into the second docking groove 531, and the docking block 54 is forced to move into the first docking groove 511 through the guiding surface 541.

[0045] The implementation principle of Embodiment 2 of the present application is as follows: After the sliding seat 2 guides the shaped charge 8 to the seabed surface 9, the control rope 41 is further relaxed to move the sliding seat 2 downward for a certain distance, so that the two hanging parts 31 disengage from the hanging holes 811. After the two hanging parts 31 disengage from the hanging holes 811, the control rope 41 is further lowered to make the limiting rod 22 abut against the seabed surface 9 to limit the further downward movement of the sliding seat 2. At this time, when the control rope 41 is lowered, the control seat 53 can move downward relative to the control rod 4. Under the action of the gravity of the control seat 53, the control seat 53 can push the docking block 54 through the guiding surface 541, so that the docking block 54 moves into the first docking groove 511. When the control seat 53 moves downward to abut against the second limiting block 44, the return spring 55 forces the docking block 54 to be inserted into the second docking groove 531, realizing the "docking" between the control seat 53 and the sliding bar 51.

[0046] Then the control rope 41 is pulled to drive the control seat 53 to move upward. The sliding bar 51 can drive the two hanging parts 31 to "open" through the pushing block 52, so as to avoid the hanging ring 81 of the shaped charge 8. When the sliding seat 2 is lifted from the seabed surface 9, the possibility that the two hanging parts 31 collide with the hanging ring 81 and cause the shaped charge 8 to deflect is reduced.

[0047] When the control base 53 drives the control rod 4 to lift off the sea level and makes the control rod 4 abut against the bottom wall of the mounting bracket 1, at this time, the unlocking rod can push the docking block 54, so that the docking block 54 is moved back into the first docking groove 511. Under the action of its own gravity and the elastic force of the compression spring 512, the sliding bar 51 can move downward relative to the control base 53 to realize the "separation" between the control base 53 and the sliding bar 51. At this time, the two hanging parts 31 can be driven by the swing bar 21 to abut against each other again, and then the hanging of the next shaped charge 8 can be carried out, improving the operation convenience of the overall structure. Embodiment 3

[0048] The embodiment of the present application discloses a safety charge placing device for underwater UXO sympathetic detonation test.

[0049] The difference between the safety charge placing device for underwater UXO sympathetic detonation test disclosed in the embodiment of the present application and Embodiment 1 is that: Refer to Figure 8 , in this embodiment, a bracket 6 is fixedly installed on the workboat (the workboat is not shown in this embodiment), a winding and unwinding roller 61 is rotatably installed on the bracket 6, and one end of the control rope 41 away from the control rod 4 is wound around the outer peripheral wall of the winding and unwinding roller 61; the bracket 6 is provided with a rotating assembly 7 for driving the winding and unwinding roller 61 to rotate.

[0050] Refer to Figure 9 , Figure 10 , the rotating assembly 7 includes a rotating disk 71, a rotating cam 72 and a rotating member. The rotating disk 71 is coaxially fixed to the outer peripheral wall of one end of the winding and unwinding roller 61. The rotating cam 72 is fixedly installed with a rotating shaft 73. One end of the rotating shaft 73 away from the rotating cam 72 is rotatably installed on the bracket 6. The rotating cam 72 is rotatably installed on the bracket 6 through the rotating shaft 73; a driving column 721 is fixedly installed on the surface of the rotating cam 72. The driving column 721 is eccentrically arranged with respect to the rotating shaft 73. A strip-shaped groove 711 for the driving column 721 to turn into is formed on the surface of the rotating disk 71. A plurality of strip-shaped grooves 711 are arranged at intervals around the central axis of the rotating disk 71. Both ends of each strip-shaped groove 711 extend along the radial direction of the rotating disk 71. When the rotating cam 72 rotates, the rotating cam 72 drives the rotating disk 71 to rotate intermittently through the driving column 721.

[0051] A rotation stop column 722 is fixedly installed on the surface of the rotation cam 72 away from the rotation axis 73. The rotation stop column 722 is cylindrical, and the outer peripheral wall of the rotation stop column 722 forms a first rotation stop surface 723. The outer peripheral wall of the rotation disk 71 has a second rotation stop surface 712. The number of the second rotation stop surfaces 712 corresponds to the number of the strip-shaped grooves 711. All the second rotation stop surfaces 712 and all the strip-shaped grooves 711 are arranged staggeredly around the central axis of the rotation disk 71. When the driving column 721 rotates out of the strip-shaped groove 711, the first rotation stop surface 723 abuts against the second rotation stop surface 712 to limit the free rotation of the rotation disk 71; when the driving column 721 rotates into the strip-shaped groove 711, the first rotation stop surface 723 disengages from the second rotation stop surface 712. For the convenience of description, hereinafter, the part of the rotation disk 71 located between two strip-shaped grooves 711 is defined as a rotation part 713, and an avoidance notch 724 for avoiding the rotation part 713 is formed on the outer peripheral wall of the rotation stop column 722.

[0052] Referring to Figure 8 , a rotating member is arranged on the bracket 6 to drive the rotation cam 72 to rotate. In this embodiment, the rotating member includes a connecting rod 74 and a force applying rod 75. One end of the connecting rod 74 is fixedly installed on the outer peripheral wall of the end of the rotation axis 73 away from the rotation cam 72, and the other end is provided with a first through hole 741. The length direction of the connecting rod 74 is perpendicular to the axial direction of the rotation axis 73. The length direction of the force applying rod 75 is parallel to the axial direction of the rotation axis 73. The force applying rod 75 slidably passes through the first through hole 741. A connecting head 751 is fixedly installed at one end of the force applying rod 75 close to the bracket 6. The outer diameter of the connecting head 751 is larger than the outer diameter of the force applying rod 75. A second through hole 62 is formed in the side wall of the bracket 6 close to the force applying rod 75. The second through hole 62 is used for the threaded insertion of the connecting head 751 (the thread is not shown in the figure). When the connecting head 751 of the force applying rod 75 is threadedly connected to the second through hole 62, the first rotation stop surface 723 of the rotation stop column 722 abuts against the second rotation stop surface 712 of the rotation disk 71. In other embodiments, the rotating member can be set as a motor to drive the rotation of the rotation axis 73.

[0053] The implementation principle of Embodiment 3 of this application is as follows: The rotation cam 72 drives the driving column 721 to perform "revolution" around the central axis of the rotation axis 73, so that it can intermittently rotate into or out of the strip-shaped groove 711. When the rotation cam 72 rotates continuously, it can drive the rotation disk 71 to perform intermittent rotation, thereby controlling the lifting and lowering of the sliding seat 2, and reducing the possibility that the hanging column 3 disengages from the hanging hole 811 when the sliding seat 2 sinks to the seabed surface 9 and the downward movement speed of the sliding seat 2 is too fast.

[0054] Through the cooperation of the first anti-rotation surface 723, the second anti-rotation surface 712 and the avoidance notch 724, when the driving column 721 is inserted into the strip-shaped groove 711, the avoidance notch 724 is used to avoid the outer wall of the rotating disc 71 at this time, so that the rotating cam 72 can drive the rotating disc 71 to rotate a certain angle through the cooperation of the driving column 721 and the strip-shaped groove 711. As the rotating cam 72 continues to rotate, when the driving column 721 exits the strip-shaped groove 711, the first anti-rotation surface 723 and the second anti-rotation surface 712 abut against each other at this time, thereby restricting the free rotation of the rotating disc 71, that is, restricting the free rotation of the winding and unwinding roller 61, reducing the possibility that the control rope 41 is rapidly lowered due to the free rotation of the winding and unwinding roller 61, and improving the control stability of the overall structure.

[0055] The above is the preferred embodiment of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
