When the data acquisition module is implemented, the data acquisition module can be any one of a data recorder, a single chip microcomputer or an embedded controller.

In practice, the target (not shown) is a ship or vessel.

The detonator for the test comprises a cylinder 300, wherein one end of the cylinder 300 is a mounting end for fixedly mounting a fuse, and the other end of the cylinder 300 is a sealing end with a sealing end face.

In addition, after the barrel 300 is adopted, the fuse can be fixed on the barrel 300 more simply, conveniently and quickly, and the test efficiency is further improved.

The number of the cylinder bodies 300 is two, and the two cylinder bodies 300 are transversely arranged and are fixedly connected through respective sealing ends in a butt joint mode.

The structure of the experimental detonator comprising the two barrels 300 is still simple, the manufacturing is easy, the cost is relatively low, and the experimental cost can be still saved.

Meanwhile, the single test detonator adopts the structure of two barrels 300, so that the test of 2 fuzes can be completed at one time, and the test efficiency is improved exponentially.

In practice, the fixing structure of the sealing ends of the two barrels 300 is preferably as follows:

In addition, the structure of the installation cavity can effectively avoid the accumulation of seabed sand grains in the installation cavity and prevent the action of the controllable mechanical claw, and the reliability is improved.

Wherein the controllable gripper comprises an acoustic responsive release 400 and a latching mechanism;

The acoustic transponder release 400 is a combination of a transponder and an acoustic release, and has acoustic signal response, acoustic positioning, and load weight release functions. The product not only can realize the response and beacon functions of the underwater acoustic positioning system, but also can complete the control of the acoustic releaser to release the anchoring load heavy object, and realize the floating function of the floating body with the heavy object.

In the technical scheme, the acoustic response releaser 400 is adopted, the locking mechanism is driven to unlock by a deck unit (the deck unit realizes remote control of the underwater acoustic releaser or the responder by applying an underwater acoustic remote control technology), and reliable release operation is realized remotely and conveniently.

In practice, the person skilled in the art knows: the acoustic transducer in the acoustic response releaser 400 is connected with the circuit board through a cable, the circuit board is connected with the battery through a cable, and the circuit board is electrically connected with the motor through a cable.

In practice, the acoustically transparent structure may be an acoustically transparent aperture or an acoustically transparent membrane through which sound can pass.

The locking mechanism comprises a locking piece 501 and a locking block 502;

the whole locking element 501 is an L-shaped plate block structure which rotates clockwise by 90 degrees, a rotating shaft 5012 is inserted through the cross-vertical intersection of the L-shaped plate block structure, and the locking element 501 is rotatably fixed on the housing 401 of the acoustic transponder releaser 400 through the rotating shaft 5012; the lower end of the vertical edge of the L-shaped plate block structure extends along the length direction of the transverse edge to form a locking hook 5011; the position of the transverse edge of the L-shaped plate block structure, which is far away from the vertical edge, is of a flat plate structure with a vertically-penetrated waist-shaped hole;

the locking block 502 is a bar-shaped block structure, the locking block 502 is fixedly connected with the lower end of an output shaft of a motor in the acoustic response releaser 400, the locking block 502 rotates along with the output shaft and enables the self-length to be consistent with the length direction of the waist-shaped hole, the self-length can penetrate through the waist-shaped hole, and the length of the locking block 502 can be abutted to the lower surface of the periphery of the waist-shaped hole and locked to be limited when the length direction of the waist-shaped hole is crossed.

When the locking mechanism is used:

in the locked state, the motor is stationary, the locking block 502 abuts against the lower surface of the periphery of the narrow portion of the kidney-shaped hole and is locked for limiting, and the locking hook 5011 hooks the annular member on the anchor body 200.

In the unlocking and releasing process, after the acoustic response releaser 400 receives a sound signal sent by the deck unit, the motor rotating shaft 5012 rotates and drives the locking block 502 to rotate, the locking piece 501 rotates around the rotating shaft 5012, the locking block 502 penetrates out of the waist-shaped hole and enables the locking hook 5011 to be unlocked, and then the barrel 300 is separated from the anchor body 200, so that the releasing action is realized.

Therefore, the locking mechanism is simple in structure and reliable in action, and can help to realize reliable underwater release operation.

During implementation, it is preferable to have a reinforcing rib between the horizontal side and the vertical side of the L-shaped plate block structure of the locking element 501, so as to enhance the structural strength of the locking element 501 and improve the reliability of locking and unlocking release.

The locking mechanism further comprises two locking piece mounting blocks 503, the two locking piece mounting blocks 503 are vertical plate-shaped structures, the two locking piece mounting blocks 503 are opposite at intervals, the upper ends of the two locking piece mounting blocks 503 are fixed on the lower end face of the shell 401 of the acoustic response releaser 400, the rotating shaft 5012 is vertically fixed between the two locking piece mounting blocks 503, and the locking hooks 5011 of the locking pieces 501 are exposed outside the two locking piece mounting blocks 503.

The two locking piece mounting blocks 503 constitute a pair of clamping blocks, which can protect the locking piece 501 therein and ensure the reliability of the rotation of the locking piece 501.

In practice, the two lock mounting blocks 503 are preferably shaped like a Chinese character 'ba' in vertical projection, the lateral edge of the L-shaped plate block structure of the locking element 501 and the rotating shaft 5012 are located in the area surrounded by the small opening side of the Chinese character 'ba', and the lateral edge of the L-shaped plate block structure of the locking element 501 and the locking block 502 are both located in the area surrounded by the large opening side of the Chinese character 'ba'. Thus, not only are the two lock mounting blocks 503 both have a bent-like structure with higher structural strength; it also effectively increases the contact surface (welding area) of the two lock mounting blocks 503 with the lower end surface of the housing 401 of the acoustic transponder release 400, and improves the fixing reliability of the two lock mounting blocks 503.

The lower end surfaces of the two locking piece mounting blocks 503 are provided with a clamping groove facing the locking hook 5011 of the locking piece 501, and the clamping groove and the locking hook 5011 can jointly form a locking collar.

The structure of the locking ring can be matched with a metal ring at the end of the steel cable 305 to obtain more reliable locking effect, ensure the reliability of the connection between the cylinder 300 and the anchor body 200 before releasing, and avoid mistaken releasing.

Wherein, the number of the acoustic response releasers 400 is two, and the two acoustic response releasers 400 are annularly and uniformly arranged in the installation cavity at intervals;

According to the technical scheme, the steel cable 305 for connecting the test detonator and the anchor body 200 is V-shaped, so that the connection between the two cylinders 300 of the test detonator is more stable.

In addition, after the above technical solution is adopted, when any one of the acoustic transponder releasers 400 fails, the other acoustic transponder releaser 400 can drive the locking mechanism to act, so that one end of the steel cable 305 can pass through the position-limiting ring 202 of the anchor body 200 and be separated, thereby completing the release. Therefore, the technical scheme can avoid the situation that acoustics cannot be recovered due to the response releaser and cause huge loss, and further ensures the reliability of the recovery of the test device.

In practice, it is preferable that the anchor body 200 includes a weight, an upper surface of the weight protrudes to form two support blocks 201 for contacting and supporting the lower sides of the two cylinders 300, and the collar is fixedly disposed at a position right below the installation cavity on the upper surface of the weight before the two support blocks 201.

In this way, the relative position and posture between the testing device and the anchor body 200 during the lowering process can be better ensured by the two supporting blocks 201, and the acoustic transponder releaser 400 can reliably receive the release signal.

the existing lifting appliance adopts a structure that a single side is provided with a releasable hook, so that in the laying process, the single side of the thunder body for the test loses the support instantly when the releasable hook is released, and the thunder body is integrally inclined to the single side where the releasable hook is located and overturns.

After the product is adopted, the structure that the installation positions of the adjacent 2 fixed hooks connected by the cables for hoisting and the installation position of the releasable hook are opposite to each other is adopted; therefore, in the moment of releasing, the whole body of the mine for the test can form support through the fixed hook on the side and the cable for hanging in the two sides of the length direction, so that the condition that the single side of the mine for the test loses support instantly to cause overturning is avoided, and the laying posture can be better kept.

2. And can also play a better protection role.

During the falling process of the test detonator during the laying: the friction force can be generated between the surface of the mine body of the hoisting cable rope and the surface of the mine body of the test mine body, and the fixed hooks and the releasable hooks of the adjacent 2 hoisting cable ropes are arranged in a staggered manner, so that the same-direction friction force is applied to the surfaces of two sides (in the length direction) of the mine body of the test mine body, the phenomenon that the same-direction friction force acts on the same side to generate larger friction (damage) and cause overturning is avoided, and a better protection effect is achieved on the test mine body.

3. Simple structure, the implementation degree of difficulty is little, easily makes and uses.

The above is only a preferred embodiment of the present invention, and it should be noted that several modifications and improvements made by those skilled in the art without departing from the technical solution should also be considered as falling within the scope of the claims.
