[0008] With the above scheme, during use, the insertion post of the carrier is inserted into the sealed floating body through the connection hole and is clamped with the release rod. After sinking to the target water area, the release rod can be driven by the motor to rotate and be separated from the insertion post, so as to realize the throwing load of the carrier. The overall structure is simple, the processing and assembly are easy, and the implementation cost is extremely low.

[0009] Preferably: a clamping groove is arranged at the top of the insertion post, a supporting surface is arranged at the end of the release rod, and the release rod can rotate to make the supporting surface be in the clamping groove or rotate to the outside of the clamping groove. With the above scheme, it is convenient for the quick loading and release of the carrier, and further improves the feasibility.

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Referring to Figures 1 to 9 the shown simple underwater throwing and floating device, which includes a sealed floating body 100 and a carrier 200. The bottom of the sealed floating body 100 has a connection hole 110, and the carrier 200 has an insertion post 210 adapted to the connection hole 110. A motor 300 is provided inside the sealed floating body 100. The motor shaft of the motor 300 is connected with a release lever 310. There is a mutually matching rotary engagement structure between the release lever 310 and the insertion post 210. The motor 300 can drive the release lever 310 to rotate to engage or disengage with the insertion post 210. A sealing structure is provided at the position where the release lever 310 and the insertion post 210 cooperate on the sealed floating body 100, and the overall comprehensive density of the sealed floating body 100 and its internal components is less than that of water. When the carrier 200 is separated from the sealed floating body 100, the sealed floating body 100 can automatically float.

[0031] In this application, a detachable connection method is adopted between the insertion post 210 and the carrier 200. In this way, when mounting, the insertion post 210 can be first inserted and locked with the release lever 310 alone, and then connected to carriers 200 of different specifications, which has better versatility.

[0032] As shown in the figure, the top of the insertion post 210 has a card slot 211. One side and both ends of the slot 211 are open. The end of the release lever 310 has a support surface 311. When the release lever 310 rotates, the support surface 311 can be placed inside the card slot 211 or rotated to the outside of the card slot 211. Both ends of the support surface 311 have stop portions 312.

[0033] During specific implementation, the release lever 310 is cylindrical, and the card slot 211 is arc-shaped. The top wall of the card slot 211 is a plane adapted to the support surface 311. When the support surface 311 is inside the card slot 211, the support surface 311 is in a posture vertically facing the top wall of the card slot 211. On the other hand, to facilitate the cooperation between the insertion post 210 and the release lever 310 after the insertion post 210 is inserted into the connection hole 110, an avoidance area is provided on one side of the end of the insertion post 210 corresponding to the opening of the card slot 211. This avoidance area is sufficient to avoid the release lever 310 in the unlocked state.

[0034] In addition, in this embodiment, the connection hole 110 is located in the middle of the sealed floating body 100. An installation seat 400 is provided at the position corresponding to the connection hole 110 inside the sealed floating body 100. The motor 300 is installed on the installation seat 400. The installation seat 400 has a fitting chamber 410. The fitting chamber 410 has a first through hole 411 and a second through hole 412 for the release lever 310 and the insertion post 210 to extend into. A sealing ring A413 is provided between the release lever 310 and the first through hole 411. The release lever 310 and the insertion post 210 respectively extend into the fitting chamber 410 through the first through hole 411 and the second through hole 412.

[0035] At the position corresponding to the connection hole 110 inside the sealed floating body 100, there is an annular boss 120. The installation seat 400 is stepped, having a first step 420 and a second step 430. The first step 420 is fixedly connected to the bottom wall of the sealed floating body 100, and the second step 430 is fixedly connected to the top of the annular boss 120. A sealing ring B431 is provided between the bottom of the second step 430 and the annular boss 120.

[0036] In this embodiment, the motor 300 is preferably a torque motor. A restricting body 500 is provided on the installation seat 400 corresponding to the release lever 310. As shown in the figure, the restricting body 500 is fixed on the first step 420. The restricting body 500 has a guiding hole 510 for the release lever 310 to pass through. At least one end of the guiding hole 510 is provided with a limiting groove 520 communicating with the guiding hole 510. The release lever 310 has a limiting block 313 cooperating with the limiting groove 520. The limiting groove 520 is arc-shaped, and its two ends respectively correspond to the locked position and the unlocked position of the release lever 310. When the release lever 310 rotates and the limiting block 313 abuts against the end of the limiting groove 520, the motor 300 stops working.

[0037] Specifically, in this embodiment, the limiting groove 520 has an approximate arc of 90 degrees, and one end thereof corresponds to the position directly above the guide hole 510. In this way, when the limiting block 313 abuts against the upper end of the limiting groove 520, the supporting surface 311 is just in a horizontal upward posture and can support the object.

[0038] refer to Figures 1 to 9 In the simple underwater loading and buoyancy device shown, in the initial state, the release rod 310 is in the release position, at which time the support surface 313 is in a vertical posture, and the plug column 210 of the carrier 200 is inserted into it through the connecting hole 110. The motor 300 drives the release rod 310 to rotate until the limit block 313 abuts against the upper end of the limit groove 520. At this time, the support surface 313 just rotates into the slot 211 and faces its top wall up and down, which can play the role of suspending the carrier 200.

[0039] When the sealing float 100 and the carrier 200 sink to the target water area together, the motor 300 drives the release rod 310 to rotate in the opposite direction until the limit block 313 abuts against the lower end of the limit groove 520, and the support surface 313 withdraws from the slot 211. The plug column 210 is not blocked in the axial direction and can naturally escape from the connecting hole 110 under the action of gravity to achieve load shedding. After the load is shelved, the overall density of the sealing float 100 is less than that of water, so it can float up and be recovered for reuse.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
