Description

Technical Field

[0001] The invention belongs to the technical field of submersibles, and in particular relates to a submersible disposable counterweight releasing structure. Background Art

[0002] When a submersible is moving underwater, it relies on its own buoyancy to rise and fall. In order to balance the weight of the submersible, it is often necessary to install counterweights inside the submersible. However, when it is moving underwater, in case of emergency, it is often necessary to discard the counterweights to ensure the depth and speed of the submersible. For example, when chasing an enemy underwater or being chased underwater, discarding a certain amount of counterweights can effectively increase the speed of the submersible, thereby speeding up the movement of the submersible when chasing or being chased. Another example: the density of seawater has an important impact on the diving depth of the submersible. If the density of seawater suddenly drops during the sneaking process, it will cause the submersible to fall rapidly, endangering the life safety of the submersible and the sneaking personnel.

[0003] The counterweights in the prior art are often bound together and can only be discarded as a whole, which has a great impact on the balance of the submersible and affects the safety of the submersible. Therefore, it is necessary to design a structure that can realize the discarding of the counterweights one by one. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a submersible disposable counterweight release structure.

[0011] As an alternative or supplement to the above structure: the telescopic lock head is in a circular tube shape, and the force transmission sleeve passes through the tube hole of the telescopic lock head.

[0012] As an alternative or supplement to the above structure: a limit nut is provided at the end of the telescopic lock head, and an annular convex edge is provided on the side wall of the force transmission sleeve, and a ring groove is formed between the limit nut and the telescopic lock head for cooperating with the annular convex edge.

Detailed Embodiment

[0019] The following will clearly and completely describe the technical solutions in the present embodiment in conjunction with the drawings. The described embodiments are only a part of the embodiments, rather than all of them. Based on the embodiments in the present solution, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present solution.

[0020] Embodiment 1 As Figures 1 to 5 shown, this embodiment designs a throw-away weight release structure for a submersible, including components such as a weight bin 1, a transmission mechanism 2, a rotating motor 3, a weight carrier assembly 4, and a weight block 5.

[0021] The weight bin 1 is arranged at the inner bottom of the submersible. A release port is provided at the bottom of the weight bin 1, and the weight block 5 can fall from the release port and then be released outside the submersible through the opened opening at the bottom of the submersible.

[0022] A plurality of weight carrier assemblies 4 are arranged in the weight bin 1; As Figure 1As shown, there can be three counterweight carrier assemblies 4 from top to bottom. The counterweight carrier assembly 4 is used to connect or release the counterweight block 5. When the counterweight carrier assembly 4 connects the counterweight block 5, the counterweight block 5 is fixed in the counterweight bin 1, and when the counterweight carrier assembly 4 releases the counterweight block 5, the counterweight block 5 can fall downward under its own gravity and be released outside the submersible.

[0023] A number of counterweight blocks 5 are arranged horizontally in the counterweight bin 1; the counterweight block 5 is U-shaped and has a vertical groove 51 and a number of arc grooves 52, and the arc grooves 52 are arranged on the groove wall of the vertical groove 51. The arc grooves 52 communicate with the cavity of the vertical groove 51. When the counterweight carrier assembly 4 rotates, it can cooperate and engage with the arc grooves 52 or separate from each other along the vertical groove 51.

[0024] The counterweight carrier assembly 4 includes components such as a carrier rod 42, a circular sleeve 43, and an extension tongue 44; both ends of the carrier rod 42 are rotatably fitted with the bin wall of the counterweight bin 1, the carrier rod 42 can rotate freely in the counterweight bin 1, and the carrier rod 42 can be driven by a rotating motor 3. The circular sleeve 43 is sleeved on the carrier rod 42, and the extension tongue 44 is fixed on the outer wall of the circular sleeve 43; the carrier rod 42, the circular sleeve 43, and the extension tongue 44 can rotate synchronously.

[0025] When the extension tongue 44 rotates from the arc groove 52 into the vertical groove 51, the end of the extension tongue 44 does not contact the counterweight block 5, so that the counterweight block 5 can be disconnected from the counterweight carrier assembly 4 where the extension tongue 44 is located. When the extension tongue 44 rotates from the vertical groove 51 into the arc groove 52, the end of the extension tongue 44 abuts against the groove wall of the arc groove 52, so that the counterweight carrier assembly 4 where the extension tongue 44 is located is connected to the counterweight block 5, restricting the extension tongue 44 from falling off the counterweight carrier assembly 4.

[0026] Since the counterweight block 5 is connected to multiple counterweight carrier assemblies 4, when the counterweight block 5 is disconnected from all the counterweight carrier assemblies 4, the counterweight block 5 can be thrown outside the submersible from the opening at the bottom of the counterweight bin 1.

[0027] The orientations of the extension tongues 44 on the same carrier rod 42 are different, so that when the carrier rod 42 rotates to different positions, the extension tongues 44 at different positions are disconnected from the corresponding counterweight blocks 5, that is: a part of the extension tongues 44 on the same carrier rod 42 still abut against the arc grooves 52 of the counterweight blocks 5, while another part of the extension tongues 44 are disconnected from the corresponding counterweight blocks 5, so that the counterweight block 5 can fall off. When the counterweight block 5 is disconnected from all the counterweight carrier assemblies 4, the counterweight block 5 can be disconnected from the counterweight carrier assembly 4, thus realizing the release of the counterweight block 5.

[0028] Each counterweight block 5 in the counterweight bin 1 can adopt different weight specifications, that is, counterweight blocks 5 with different weight specifications are combined and used. Thus, when it is necessary to release a set weight of counterweight blocks 5, the corresponding counterweight blocks 5 can be directly released by rotating the counterweight carrier assembly 4, thereby achieving precise control of the weight of the submersible.

[0029] Embodiment 2 As Figure 2 and Figure 3 shown, on the basis of the structure of Embodiment 1, a transmission mechanism 2 is provided between the counterweight carrier assembly 4 and the rotating motor 3, and the rotating motor 3 can control the rotation of the counterweight carrier assembly 4 through the transmission mechanism 2.

[0030] An installation cylinder 11 is provided on the wall of the counterweight bin 1, and the transmission mechanism 2 is arranged at the installation cylinder 11. One end of the installation cylinder 11 is closed, so as to prevent the water in the counterweight bin 1 from entering the rotating motor 3 and ensure the safety of the rotating motor 3.

[0031] The transmission mechanism 2 includes a first magnet 21, a second magnet 22, a force transmission rod 23, a force transmission sleeve 24, a third magnet 25 and a fourth magnet 26; the first magnet 21 is connected to the output shaft of the rotating motor 3 and is arranged in the installation cylinder 11 of the second magnet 22 and magnetically coupled with the first magnet 21; the force transmission rod 23 is coaxially connected to the second magnet 22, the force transmission sleeve 24 is in sliding key connection with the force transmission rod 23, the force transmission sleeve 24 is coaxially connected to the third magnet 25, and the fourth magnet 26 is coaxially fixedly connected to the carrier rod 42 and magnetically coupled with the third magnet 25.

[0032] When the rotating motor 3 drives the first magnet 21 to rotate, due to the magnetic coupling between the first magnet 21 and the second magnet 22, the second magnet 22 can rotate synchronously. The second magnet 22 can drive the force transmission rod 23 to rotate. Since a key groove is provided on the inner wall of the force transmission sleeve 24 and is in key connection with the force transmission sleeve 24, the force transmission rod 23 can axially slide relative to the force transmission sleeve 24, and the two cannot rotate relative to each other. The force transmission sleeve 24 can drive the carrier rod 42 to rotate through the third magnet 25 and the fourth magnet 26, thereby realizing the rotation control of the counterweight carrier assembly 4.

[0033] Embodiment 3 As Figure 4 shown, on the basis of the structure of Embodiment 2, when the submersible encounters an emergency, it may be necessary to discard all the counterweight blocks 5. For this reason, this embodiment designs a locking component 6 that can lock or unlock the counterweight carrier assembly 4. When the counterweight carrier assembly 4 is unlocked, the counterweight carrier assembly 4 and the counterweight blocks 5 can be discarded together.

[0034] Specifically, a locking component 6 is respectively arranged on the bin walls on the opposite sides of the counterweight bin 1, and the locking component 6 can be specifically installed at the installation cylinder 11.

[0035] The locking component 6 includes components such as a transmission ring 61, a telescopic lock head 62, a limit nut 63, and a compression spring 64.

[0036] The telescopic lock head 62 is arranged in the installation cylinder 11 and can telescopically move; an end sleeve 41 is arranged at the end of the carrier rod 42; when the telescopic lock head 62 extends out of the installation cylinder 11 and is inserted and connected with the end sleeve 41, the telescopic lock head 62 provides support for the counterweight carrier assembly 4; when the telescopic lock head 62 retracts into the installation cylinder 11 and disengages from the end sleeve 41, the counterweight carrier assembly 4 and the counterweight block 5 fall off together and fall out of the submersible.

[0037] The telescopic lock head 62 can be in a circular tube shape to facilitate the transmission sleeve 24 to pass through the tube hole of the telescopic lock head 62.

[0038] A limit nut 63 is arranged at the end of the telescopic lock head 62, and an annular convex edge is arranged on the side wall of the transmission sleeve 24. A ring groove for cooperating with the annular convex edge is formed between the limit nut 63 and the telescopic lock head 62.

[0039] The end of the telescopic lock head 62 abuts against the inner wall of the installation cylinder 11 through a compression spring 64, so as to use the compression spring 64 to provide an outward thrust for the telescopic lock head 62 to prevent the telescopic lock head 62 from rotating and retracting into the installation cylinder 11 under the action of the vibration force of the submersible.

[0040] A transmission ring 61 is sleeved outside the installation cylinder 11. The magnets on the transmission ring 61 are magnetically coupled with the magnets on the telescopic lock head 62. The transmission ring 61 can be connected to the motor through a belt and thus driven by the motor. The telescopic lock head 62 is threadedly connected with the installation cylinder 11. When the transmission ring 61 rotates, the telescopic lock head 62 can also rotate accordingly, thereby controlling the extension or retraction action of the telescopic lock head 62.

[0041] The above embodiments are only examples for clear illustration and not limitations on the implementation manners; it is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present technology.
