Description

Technical Field

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

[0002] When submersibles are moving underwater, they rely on their own buoyancy to ascend and descend. To balance the submersible's weight, they often need to install counterweights. However, in emergencies, submersibles often need to jettison counterweights to maintain depth and speed. For example, when pursuing an enemy underwater, or when being pursued, jettisoning counterweights can effectively increase the submersible's speed, thereby accelerating its movement during pursuit or attack. Another example is the density of seawater, which significantly affects a submersible's diving depth. A sudden drop in seawater density during submersion can cause the submersible to rapidly descend, endangering both the submersible and the personnel.

[0003] The counterweights in the prior art are often bound together and can only be discarded as a whole, which has a greater impact on the balance of the submersible and affects the safety of the submersible. For this reason, 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.

[0007] The counterweight block is U-shaped and has a vertical groove and a plurality of arc grooves, and the arc grooves are arranged on the groove wall of the vertical groove;

[0015] 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.

[0016] As an alternative or supplement to the above structure: a limiting nut is provided at the end of the telescopic lock head, an annular convex edge is provided on the side wall of the force transmission sleeve, and an annular groove that cooperates with the annular convex edge is formed between the limiting nut and the telescopic lock head.

[0017] As an alternative or supplement to the above structure: the end of the telescopic lock head is pressed against the inner wall of the installation cylinder through a compression spring.

DETAILED DESCRIPTION

[0027] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0028] Example 1

[0029] like Figures 1 to 5 As shown, this embodiment designs a submersible disposable counterweight release structure, including a counterweight compartment 1, a transmission mechanism 2, a rotating motor 3, a counterweight supporting assembly 4, a counterweight block 5 and other components.

[0030] The counterweight bin 1 is arranged at the bottom of the submersible. A release port is provided at the bottom of the counterweight bin 1. The counterweight block 5 can fall from the release port and then be released outside the submersible from the open opening at the bottom of the submersible.

[0031] There are multiple counterweight support components 4 in the counterweight bin 1; Figure 1 As shown, there can be three counterweight supporting assemblies 4 from top to bottom. The counterweight supporting assemblies 4 are used to connect or release the counterweight block 5. When the counterweight supporting assembly 4 is connected to the counterweight block 5, the counterweight block 5 is fixed in the counterweight compartment 1. When the counterweight supporting assembly 4 releases the counterweight block 5, the counterweight block 5 can fall downward under its own weight and be released outside the submersible.

[0032] Several counterweight blocks 5 are arranged horizontally within the counterweight bin 1. The counterweight blocks 5 are U-shaped and have a vertical slot 51 and several arcuate slots 52. The arcuate slots 52 are arranged on the walls of the vertical slot 51. The arcuate slots 52 communicate with the groove cavity of the vertical slot 51. When the counterweight supporting assembly 4 rotates, it can engage with the arcuate slots 52 or separate from each other along the vertical slots 51.

[0033] The counterweight supporting assembly 4 includes a supporting rod 42, a circular sleeve 43, and an extension tongue 44. The ends of the supporting rod 42 are rotatably engaged with the walls of the counterweight bin 1, allowing the supporting rod 42 to rotate freely within the counterweight bin 1. The supporting rod 42 can be driven by the rotating motor 3. The circular sleeve 43 is sleeved onto the supporting rod 42, and the extension tongue 44 is fixed to the outer wall of the circular sleeve 43. The supporting rod 42, circular sleeve 43, and extension tongue 44 can rotate synchronously.

[0034] When the extension tongue 44 rotates from the circular arc groove 52 into the vertical groove 51, the end of the extension tongue 44 does not contact the counterweight 5, thereby allowing the counterweight 5 to be disconnected from the counterweight supporting assembly 4 where the extension tongue 44 is located. When the extension tongue 44 rotates from the vertical groove 51 into the circular arc groove 52, the end of the extension tongue 44 abuts against the groove wall of the circular arc groove 52, thereby connecting the counterweight supporting assembly 4 where the extension tongue 44 is located with the counterweight 5, and preventing the extension tongue 44 from falling off the counterweight supporting assembly 4.

[0035] Since the counterweight block 5 is connected to multiple counterweight supporting assemblies 4, when the counterweight block 5 is disconnected from all the counterweight supporting assemblies 4, the counterweight block 5 can be thrown out of the submersible from the opening at the bottom of the counterweight bin 1.

[0036] The extension tongues 44 on the same supporting rod 42 have different orientations, so that when the supporting rod 42 is rotated to different positions, the extension tongues 44 at different positions are disconnected from the corresponding counterweight 5. That is, a portion of the extension tongues 44 on the same supporting rod 42 still abut against the arc groove 52 of the counterweight 5, while another portion of the extension tongues 44 are disconnected from the corresponding counterweight 5, allowing the counterweight 5 to fall off. When the counterweight 5 is disconnected from all the counterweight supporting assemblies 4, the counterweight 5 can be disconnected from the counterweight supporting assemblies 4, thereby achieving the release of the counterweight 5.

[0037] The ballast blocks 5 in the ballast bin 1 can be of different weight specifications, that is, ballast blocks 5 of different weight specifications can be used in combination. Therefore, when a ballast block 5 of a set weight needs to be released, the corresponding ballast block 5 can be released directly by rotating the ballast support assembly 4, thereby achieving precise control of the submersible weight.

[0038] Example 2

[0039] like Figure 2 and Figure 3 As shown, based on the structure of Example 1, a transmission mechanism 2 is provided between the counterweight supporting assembly 4 and the rotating motor 3 , and the rotating motor 3 can control the rotation of the counterweight supporting assembly 4 through the transmission mechanism 2 .

[0040] The silo wall of the counterweight silo 1 is provided with a mounting tube 11, and the transmission mechanism 2 is provided at the mounting tube 11. One end of the mounting tube 11 is closed, thereby preventing water in the counterweight silo 1 from entering the rotating motor 3, thereby ensuring the safety of the rotating motor 3.

[0041] 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, is arranged in the second magnet 22 mounting tube 11 and is 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 connected to the force transmission rod 23 by a sliding key, the force transmission sleeve 24 is coaxially connected to the third magnet 25, and the fourth magnet 26 is coaxially fixedly connected to the supporting rod 42 and is magnetically coupled with the third magnet 25.

[0042] When the rotating motor 3 drives the first magnet 21 to rotate, the magnetic coupling between the first magnet 21 and the second magnet 22 enables the second magnet 22 to rotate synchronously. The second magnet 22 can also drive the force transmission rod 23 to rotate. Because the force transmission sleeve 24 is provided with a keyway on its inner wall and is keyed to the force transmission sleeve 24, the force transmission rod 23 can slide axially relative to the force transmission sleeve 24, and the two cannot rotate relative to each other. The force transmission sleeve 24 can drive the support rod 42 to rotate via the third magnet 25 and the fourth magnet 26, thereby achieving rotational control of the counterweight support assembly 4.

[0043] Example 3

[0044] like Figure 4 As shown, based on the structure of Example 2, when the submersible encounters an emergency, it may be necessary to discard all the counterweight blocks 5. For this reason, this embodiment is designed with a locking assembly 6, which can lock or unlock the counterweight supporting assembly 4. When the counterweight supporting assembly 4 is unlocked, the counterweight supporting assembly 4 can be discarded together with the counterweight blocks 5.

[0045] Specifically, a locking assembly 6 is respectively provided on the warehouse walls on two opposite sides of the counterweight warehouse 1 , and the locking assembly 6 can be specifically installed at the installation cylinder 11 .

[0046] The locking assembly 6 includes a transmission ring 61 , a telescopic lock head 62 , a limit nut 63 , a compression spring 64 and other components.

[0047] The telescopic lock head 62 is arranged in the mounting tube 11 and can be telescopically moved; the end of the supporting rod 42 is provided with an end sleeve 41; when the telescopic lock head 62 extends out of the mounting tube 11 and is plugged into the end sleeve 41, the telescopic lock head 62 provides support for the counterweight supporting assembly 4; when the telescopic lock head 62 retracts into the mounting tube 11 and disengages from the end sleeve 41, the counterweight supporting assembly 4 falls off together with the counterweight block 5 and falls out of the submersible.

[0048] The telescopic lock head 62 may be in a circular tube shape so that the force transmission sleeve 24 can pass through the tube hole of the telescopic lock head 62 .

[0049] A limiting nut 63 is provided at the end of the telescopic lock head 62 , and an annular convex edge is provided on the side wall of the force transmission sleeve 24 . An annular groove that cooperates with the annular convex edge is formed between the limiting nut 63 and the telescopic lock head 62 .

[0050] The end of the telescopic lock head 62 is pressed against the inner wall of the mounting tube 11 through the compression spring 64, so that the compression spring 64 provides an outward thrust for the telescopic lock head 62 to prevent the telescopic lock head 62 from rotating and retracting into the mounting tube 11 under the vibration force of the submersible.

[0051] The mounting tube 11 is provided with a transmission ring 61. The magnets on the transmission ring 61 are magnetically coupled to the magnets on the telescopic lock 62. The transmission ring 61 can be connected to a motor via a belt, thereby being driven by the motor. The telescopic lock 62 is threadedly connected to the mounting tube 11. When the transmission ring 61 rotates, the telescopic lock 62 can also rotate with it, thereby controlling the extension or retraction of the telescopic lock 62.

[0052] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
