DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a volume-adjustable underwater vehicle water tank of the present invention comprises a tank body 1 and a movable plate 2.

[0026] The box 1 stores water. Three pairs of water pipes 11 are provided on the box 1, and the water pipes 11 are used for filling and draining water from each cavity. Since the three water tanks are combined into one in the present application, the shape of the box 1 is similar to a horizontal rectangular parallelepiped.

[0027] Two movable plates 2 are arranged at intervals in the box body 1 and divide the interior of the box body 1 into a first cavity 101 and two second cavities 102. In order to ensure the sealing isolation between the cavities, a sealing ring is arranged on the surface of the movable plate 2 in contact with the inner wall of the box body 1, so that the movable plate 2 and the inner wall of the box body 1 can achieve movable sealing contact, so that the first cavity 101 is arranged between the two second cavities 102 and the cavities are isolated from each other. The plate surface of each movable plate 2 is arranged perpendicular to the ground, and each movable plate 2 moves horizontally relative to the box body 1, and adjusts the volume ratio of the first cavity 101 and the two second cavities 102; the first cavity 101 and the two second cavities 102 are respectively connected to each pair of water pipes 11.

[0028] The present application is very flexible in the method of controlling the buoyancy and steering angle of the underwater vehicle. You can choose not to move the movable plate 2 and change the volume of each cavity, and use the conventional method of injecting and discharging water into each cavity through the corresponding water pipes connected to each cavity to change the water storage capacity of each cavity to adjust the buoyancy, and change the center of gravity of each cavity by changing the water storage capacity to achieve the adjustment of the steering angle. At the same time, when performing steering angle control, the present application can change the center of gravity of the water stored in one of the second cavities 102 by moving one of the movable plates 2; for example Figure 2 In the figure, when the movable plate 2 located on the left side moves to the left, the volume of the second cavity 102 on the left side is compressed and the volume of the first cavity 101 is expanded. The preset volume of the second cavity 102 and the water storage capacity of the first cavity 101 will not change. Changing the volumes of the two cavities will cause the water storage level in the second cavity 102 to rise and the water storage level in the first cavity 101 to drop, thereby causing the center of gravity of the second cavity 102 on the left side to move left and upward, and the center of gravity of the first cavity 101 to move left and downward, while the center of gravity of the second cavity 102 on the right side remains unchanged. According to the buoyancy adjustment principle of the water tank vehicle, the above changes will cause the center of gravity of the vehicle to deviate to the left, causing the vehicle to tilt to the left and turn left. At the same time, since the center of gravity of the first cavity 101 located in the middle is lower than the center of gravity of the second cavity 102 located on the outside, a structure similar to a seesaw is formed, so that the center of gravity of the first cavity 101 presses the center of gravity of the second cavity 102, thereby avoiding the problem of the vehicle overturning due to excessive tilt angle.

[0029] exist Figure 1 In a preferred embodiment shown, the movable sealing contact between the movable plate 2 and the inner wall of the box body 1 is difficult to achieve in actual production, so in the specific implementation, it also includes a first inner liner 3, a second inner liner 4 and a bellows 5.

[0030] The first inner container 3 is sleeved in the box body 1 and communicated with one of the pair of water pipes 11. The first inner container 3 is open on two sides facing the two second inner containers 4.

[0031] The two second inner tanks 4 are sleeved in the box body 1 and arranged on both sides of the first inner tank 3 in the horizontal direction, and are connected to a pair of water pipes 11 in a one-to-one correspondence. The two second inner tanks 4 are open to the sides of the first inner tank 3. The inner tank has two functions: one is to connect with the box body 1 through reinforcing ribs to enhance the structural pressure resistance of the water tank, and the other is to serve as a fixed part in each cavity so that each cavity can be connected to the water pipe 11 for filling and draining.

[0032] Each movable plate 2 is respectively arranged between the first inner liner 3 and the second inner liner 4 , and the movable plate 2 moves horizontally between the first inner liner 3 and the second inner liner 4 .

[0033] The bellows 5 can be stretched and retracted along the extension direction of its two ends, and the volume of each cavity can be adjusted by using the telescopic performance of the bellows 5. The bellows 5 is arranged between the movable plate 2 and the second inner liner 4 and between the movable plate 2 and the first inner liner 3, and one end of the bellows 5 abuts against the plate surface of the movable plate 2; the other end of the bellows 5 is connected to the open side of the first inner liner 3, so that the two bellows 5, the first inner liner 3 and the two movable plates 2 form a first cavity 101; or the other end of the bellows 5 is connected to the open side of the second inner liner 4, so that the bellows 5, the second inner liner 4 and the movable plate 2 form a second cavity 102. It should be noted that in order to improve the compressive strength of the bellows 5, a bellows 5 of inner liner reinforcement or strengthening type can be used.

[0034] exist Figure 2 In a preferred embodiment shown, since water waves will be generated on the liquid surface of each cavity when each cavity is filled or drained through the water pipe 11, the water waves will impact the inner wall of the cavity and cause the water tank to shake. Therefore, considering the anti-swaying requirements of the water tank, a partition 6 is also included.

[0035] Among them, the bellows 5 includes a fixed part 51 and a deformable part 52; the two ends of the bellows 5 are fixed parts 51 and are sealed and connected to the plate surface of the movable plate 2 or the open side of the first inner liner 3 or the open side of the second inner liner 4 through the fixed parts 51; a plurality of fixed parts 51 and a plurality of deformable parts 52 are alternately arranged along the extension direction of the two ends of the bellows 5, and the deformable part 52 is connected between two adjacent fixed parts 51 and can stretch and shrink, and drive the fixed part 51 to move.

[0036] The partition 6 is arranged in the first cavity 101 or the second cavity 102. The partition 6 is sleeved in the fixing portion 51 and moves synchronously with the fixing portion 51; the partition 6 is arranged on the fixing portion 51 without hindering the expansion and contraction performance of the bellows 5. The partition 6 is provided with a through hole 601, and the spaces on both sides of the partition 6 are connected through the through hole 601. The arrangement structure of multiple partitions 6 can effectively offset the impact force of water waves, thereby reducing the impact of water waves on the inner wall of the cavity and weakening the shaking of the water tank.

[0037] exist Figure 2 In a preferred embodiment shown, the partition 6 is also arranged in the open mouth of the first inner liner 3, or the partition 6 is also arranged in the open mouth of the second inner liner 4, so that the partition 6 can also be arranged in each inner liner to play a role in preventing waves and swaying.

[0038] exist Figure 1 In a preferred embodiment shown, when the movable plate 2 is located in the middle of the first inner liner 3 and the second inner liner 4, the bellows 5 is in a relaxed state, thereby avoiding the problem of shortening the service life of the bellows 5 due to the bellows 5 always being in a compressed or stretched state.

[0039] exist Figure 2In a preferred embodiment shown, the maximum movement distance of the movable plate 2 is not greater than the difference between the maximum extension length of the bellows 5 and the minimum retraction length of the bellows 5, thereby limiting the movement range of the movable plate 2 to effectively control the change in cavity volume.

[0040] exist Figure 1 In a preferred embodiment shown, the lengths of the first inner liner 3 and the second inner liner 4 along the extension direction of the two ends of the bellows 5 are smaller than the length of the bellows 5 in the extension direction, so that the inner liner is as small as possible and the bellows 5 is as long as possible, so that each cavity has more sufficient volume change space.

[0041] exist Figure 3 A preferred embodiment shown in the figure further includes a driving assembly 7 which is arranged outside the box body 1 and is used to drive the movable plate 2 to reciprocate between the first inner liner 3 and the second inner liner 4 .

[0042] exist Figure 3 In a preferred embodiment shown, the driving assembly 7 includes a slider 71 and a driving mechanism 72 .

[0043] A slide groove 103 is provided on the outer wall of the box body 1 , and two ends of the slide groove 103 extend along the extending direction of two ends of the corrugated tube 5 .

[0044] The slider 71 is disposed in the slide groove 103 and moves along the slide groove 103 . One end of the slider 71 is inserted into the box body 1 and connected to the movable plate 2 . The other end of the slider 71 passes through the slide groove 103 and extends to the outside of the box body 1 .

[0045] The driving mechanism 72 is disposed on the outer wall of the box body 1 and is located at one end of the slide groove 103. The driving mechanism 72 is connected to the slider 71 and drives the slider 71 to reciprocate along the slide groove 103. The driving mechanism 72 drives the slider 71 to reciprocate, thereby driving the movable plate 2 to reciprocate between the first inner liner 3 and the second inner liner 4 to adjust the volume of each cavity. When the driving mechanism 72 is directly connected to the slider 72, the driving mechanism 72 is a linear output mechanism, specifically, a pneumatic telescopic rod or a hydraulic telescopic rod.

[0046] exist Figure 3 In a preferred embodiment shown, the drive assembly 7 further includes a screw rod 73 .

[0047] Among them, one end of the screw 73 is connected to the driving mechanism 72 and is driven by the driving mechanism 72 to rotate the lower shaft, and the other end of the screw 73 extends along the extension direction of the slide slot 103, and the free end of the slider 71 is screwed to the screw 73. At this time, the driving mechanism 72 is a rotary output mechanism, specifically, a rotary motor; through the above scheme, the moving distance of the movable plate 2 is accurately controlled, and the volume change of each cavity is accurately controlled.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
