[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a buoyancy adjustment system for an underwater vehicle, such as Figure 1-11 As shown, the buoyancy adjustment system of the underwater vehicle includes: an underwater vehicle body 1 and a plurality of drainage ends 2 arranged on the underwater vehicle body 1; a plurality of connection frames 3 all fixedly mounted on one side of the underwater vehicle body 1, and the plurality of connection frames 3 are respectively covered on the plurality of drainage ends 2; a group of sealing plates 4 hinged in the connection frames 3 for shielding the drainage ends 2, and a group of the sealing plates 4 is located on one side of the drainage ends 2 and is inclined; a group of support plates 5 fixedly mounted on one side of the inner wall of the connection frames 3; a group of reset springs 6 respectively fixedly mounted on a group of the support plates 5 for resetting a group of the sealing plates 4, and the tops of a group of the reset springs 6 are respectively fixedly connected to a group of the sealing plates 4; an opening and closing mechanism arranged on the connection frames 3 for opening and closing a group of the sealing plates 4.

[0035] In this embodiment, when the drainage end 2 is used, the opening and closing mechanism is first started to drive a group of sealing plates 4 to move, so that a group of sealing plates 4 rotate along the connecting frame 3, and then a group of sealing plates 4 are moved away from each other, so that the drainage end 2 is exposed, and then the drainage end 2 performs the drainage and filling operations. When the buoyancy of the underwater vehicle body 1 is adjusted, the water body can be discharged through at least one drainage end 2, and the posture of the underwater vehicle body 1 is assisted by the reaction force generated by the drainage. After the adjustment, the opening and closing mechanism is started to release the cable 10, and the reset spring 6 is contracted at the same time to reset the sealing plate 4 and seal the drainage end 2;

[0036] When the posture of the underwater vehicle body 1 needs to be adjusted with the head downward, the head water tank needs to be filled with water and the other water tanks need to be drained. The drainage pipeline can spray the drainage water upward from the head and downward from the tail to assist in posture adjustment. After the posture adjustment is completed or the water is discharged, the opening and closing mechanism is closed to protect the drainage pipeline. Through this auxiliary adjustment, the posture adjustment speed of the underwater vehicle can be accelerated, making the underwater vehicle more flexible, while avoiding the disturbance of the fixed drainage position during the posture adjustment of the underwater vehicle. A group of sealing plates 4 are driven by the opening and closing mechanism to perform the opening and closing operation, thereby protecting the drainage end 2, which can effectively prevent biological attachment in the pipe mouth, while avoiding affecting the operation of the buoyancy adjustment system, reducing the probability of failure, and having a good protection effect. A group of sealing plates 4 are reset by the reset spring 6, so that they can seal the connecting frame 3, which is beneficial to the protection operation of the drainage end 2.

[0037] In a further preferred embodiment of the present invention, the opening and closing mechanism includes: an installation box 7 fixedly installed on one side of the connecting frame 3; a rotating rod 8 rotatably installed in the installation box 7; a group of guide wheels 9 fixedly installed on the connecting frame 3; a cable 10 wound on the rotating rod 8, one end of the cable 10 extends out of the installation box 7 and is fixedly connected to the sealing plate 4, and the cable 10 is in rotational contact with the guide wheel 9; and a driving mechanism provided on the installation box 7 for driving the rotating rod 8.

[0038] In this embodiment, when the driving mechanism is started, the cable 10 is wound, and then the cable 10 is rotated along the guide wheel 9, so that the cable 10 drives the sealing plate 4 to move, and the sealing plate 4 is rotated along the connecting frame 3, so as to perform an opening and closing operation, and the drainage end 2 is covered or exposed. By winding the cable 10 around the rotating rod 8, the opening and closing operation of the sealing plate 4 is achieved, and the operation is relatively quick and efficient. The cable 10 is guided by the guide wheel 9, so as to reduce the friction between the cable 10 and the sharp corners of the connecting frame 3, and the cable 10 can be effectively protected, thereby reducing the wear of the cable 10, which is beneficial to extending the service life of the cable 10.

[0040] When the sealing plate 4 needs to be opened, the first motor 13 is first started, so that the output shaft of the first motor 13 drives the rotating rod 8 to rotate, so that the rotating rod 8 winds the cable 10. When the cable 10 is wound, one end of the cable 10 drives the sealing plate 4 to move, so that the sealing plate 4 rotates along the connecting frame 3. Since a group of driving mechanisms are provided on the connecting frame 3, the rotating rod 8 drives the first sprocket 11 to rotate synchronously when the rotating rod 8 rotates, so that the first sprocket 11 drives the first chain 12 to rotate, and the first chain 12 drives a group of first sprockets 11 to rotate synchronously, so that a group of rotating rods 8 rotate synchronously, and a group of cables 10 are synchronously wound and unwound, so that a group of sealing plates 4 rotate synchronously, and a group of sealing plates 4 rotate away from each other to expose the drainage end 2. The first sprocket 11 and the first chain 12 are used in combination, so that a group of rotating rods 8 are driven at the same time to drive a group of sealing plates 4 to rotate synchronously, so as to achieve the effect of shielding or exposing the drainage end 2, and the operation efficiency is relatively high.

A hydraulic cylinder 23 is fixedly installed on one side of the inner wall of the connecting box 20, and the output rod of the hydraulic cylinder 23 is fixedly connected to the rack 22.

The rack 22 is driven to slide by the hydraulic cylinder 23, and then the rack 22 drives the driving gear 21 to rotate. When the driving gear 21 rotates, it simultaneously drives the connecting rod 18 to rotate, thereby realizing the swinging operation of the scraper 19, which is beneficial to the scraper 19 to clean the protective net box 15.

Then, the water pump 29 is started, so that the water pump 29 pumps the water in the water storage tank 25 into the corresponding connecting pipe 28, so that the water body enters the corresponding drainage cavity and discharges water through the corresponding drain pipe 32. Then, the drain pipe 32 discharges the water into the connecting pipe 31, so that the connecting pipe 31 discharges the water into the drainage end 2 for drainage operation. Through the setting of two drainage cavities, the multiple drainage ends 2 can be separately drained and filled with water, so that when the attitude of the underwater vehicle body 1 needs to be adjusted, the multiple drainage ends 2 can be used in combination to adjust the attitude of the underwater vehicle body 1, and the adjustment efficiency is relatively high.
