Description

Technical Field

[0001] The invention belongs to the technical field of underwater operations, and specifically relates to underwater experimental equipment with adjustable weight and buoyancy. Background Art

[0002] Underwater experimental equipment with adjustable weight and buoyancy usually refers to an underwater device that can flexibly adjust its own gravity and buoyancy balance according to its working requirements or environmental conditions. This equipment can achieve suspension, floating, diving and other actions in water by changing its own weight or buoyancy, thereby meeting specific underwater experiments or operation requirements. It can maintain a stable suspension state in a complex underwater environment and flexibly adjust buoyancy and gravity as needed. This equipment has broad application prospects in marine scientific research, underwater engineering operations, underwater resource exploration and other fields.

[0003] The prior art has also proposed some solutions: for example, a patent with publication number CN116902761A discloses a deployment and recovery device and method for underwater experimental equipment with adjustable weight and buoyancy, including a lifting device module, a lifting guide module, an experimental frame module, a lifting rope, and a jettisonable counterweight module. When the experimental device needs to be recovered, the hydraulic rod of the jettisonable counterweight module drives the slider to move outward, away from the counterweight block, and the counterweight block and the anti-sinking cylinder are separated from the experimental device, and the jettisoning is completed; the lifting equipment on the sea surface pulls the lifting beam module to drive the lifting rope and the guide cylinder to move horizontally toward the top of the experimental device; when it is detected that the lifting beam module has tightened the lifting rope, the lifting equipment pulls the experimental device upward to leave the seabed and gradually rise to the sea surface, and the recovery process ends.

[0004] Traditional underwater equipment usually relies on vertical thrusters to adjust the diving depth, which requires continuous energy input. Vertical thrusters consume a lot of energy when working, especially when the diving depth needs to be adjusted frequently or long-term deep diving is required. The energy consumption problem is more prominent, which increases operating costs and may also pose a challenge to the endurance of the equipment, limiting the operating time and scope of the underwater equipment.

[0011] Preferably, a filter grille is arranged on one side of each of the plurality of water storage chambers. The filter grilles are all in a conical shape. The outer diameter of one end of the water storage chamber is smaller than the outer diameter of one end of the filter grille. Drainage plates are fixedly connected to the outer walls of the plurality of filter grilles. One side of the drainage plate is fixedly connected to the outer wall of the water storage chamber.

[0012] Preferably, the charging and discharging assembly includes a plurality of air storage cylinders. The plurality of air storage cylinders correspond to the plurality of airbag pads one by one. A second inner piston is slidably connected to the inner wall of each air storage cylinder. A connecting air pipe is fixedly communicated with the bottom side of each air storage cylinder. The end of the connecting air pipe far from the air storage cylinder is fixedly connected to one side of the airbag pad. A power assembly is arranged above the second inner piston.

[0018] 1. For the underwater experimental equipment with adjustable heavy buoyancy of the present invention, seawater is sucked into the interiors of two water storage buckets through the suction and discharge assembly. At this time, since the water storage buckets are fixedly installed inside the equipment main body through the clamping members, when the mass of the water storage buckets increases, the mass of the equipment main body will increase, thereby causing the equipment main body to sink into the water. And the volume of the sucked seawater can be controlled to control the diving depth of the equipment main body. This method is more energy-saving and reduces the energy consumption required for long-term use of the vertical thruster.

[0019] 2.

The equipment main body can maintain stability at any height when diving to the bottom of the water. And when the equipment main body floats, by changing the buoyancy, the equipment main body is easier to float, can more effectively resist the influence of water pressure, and makes the equipment float more smoothly.

[0020] 3. An underwater experimental device with adjustable heavy buoyancy according to the present invention intercepts impurities in seawater by arranging a filter grille on one side of the water tank, avoiding large stone particles in the water from entering the interior of the water storage bucket along with the seawater. When draining water, the stone particles cannot be completely discharged and will get stuck inside the water storage bucket and the water pipe. Accumulation may block the interior of the water pipe and the water storage bucket, resulting in a decrease in fluidity and affecting the total mass of the inhaled seawater. Moreover, since the filter grille is conical in shape, the intercepted stone particles will flow along the surface of the filter grille under the action of suction and be dispersed to various parts of the seawater through the drainage plate.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] As Figures 1 to 10 shown, the present invention provides a technical solution: an underwater experimental equipment with adjustable heavy buoyancy, including an equipment main body 1. The inner walls of the equipment main body 1 are symmetrically and fixedly connected with clamping pieces 2. The inner walls of the two clamping pieces 2 are fixedly connected with water storage buckets 3. On one side of the equipment main body 1, spotlights 31 are symmetrically and fixedly installed. On one side of each of the two spotlights 31, there is a camera 32 which is also fixedly installed on one side of the equipment main body 1. On the top of the equipment main body 1, there are a plurality of airbag pads 23. On the outside of each of the two water storage buckets 3, there is a suction and discharge assembly for sucking or discharging seawater into or out of the interiors of the two water storage buckets 3. On the top of the equipment main body 1, there is a charging and discharging assembly for inflating or deflating the plurality of airbag pads 23.

[0035] During operation: In the initial state, both of the two water storage buckets 3 are empty and dry inside, and a large amount of gas has been filled into the multiple air cushions 23. At this time, since the overall mass of the equipment main body 1 is relatively light and the multiple air cushions 23 apply an upward buoyant force to the equipment main body 1, the equipment main body 1 will stay on the water surface, and the operator can check whether some parts outside the equipment main body 1 are operating normally. When it is necessary to make the entire equipment main body 1 dive into the water, seawater is sucked into the two water storage buckets 3 through the suction and discharge assembly. At this time, since the water storage buckets 3 are fixedly installed inside the equipment main body 1 through the clamping members 2, when the mass of the water storage buckets 3 increases, the mass of the equipment main body 1 will increase, thereby causing the equipment main body 1 to sink into the water. And the volume of the sucked seawater can be controlled to control the diving depth of the equipment main body 1. When seawater is sucked into the two water storage buckets 3, the multiple air cushions 23 will deflate through the inflation and deflation assembly at this time. After the air cushions 23 deflate, the volume decreases, resulting in a decrease in the buoyant force received by the equipment main body 1. Moreover, the more seawater the water storage buckets 3 suck in, the more the air cushions 23 deflate, so that the buoyant force of the equipment main body 1 decreases while the mass increases, completing the entire diving process. After that, the seabed conditions are explored and measured through the spotlight 31 and the camera 32. When the equipment main body 1 needs to float up after the test is completed, the seawater inside the two water storage buckets 3 is discharged through the suction and discharge assembly, and the inflation and deflation assembly inflates the multiple air cushions 23. The mass of the equipment main body 1 decreases and the buoyant force increases, so as to perform the floating operation. By sucking in and discharging seawater through the suction and discharge assembly to control the diving and floating of the equipment main body 1, this method is more energy-efficient, reducing the energy consumption required for long-term use of the vertical thruster. And through the inflation and deflation assembly, the buoyant force of the equipment main body 1 is adjusted, and in cooperation with the gravity adjustment of the equipment main body 1 by the suction and discharge assembly, the two can accurately control the diving depth of the equipment main body 1. The equipment main body 1 can maintain stability at any height when diving to the bottom of the water. And when the equipment main body 1 floats up, by changing the buoyant force, the equipment main body 1 is easier to float up, and can more effectively resist the influence of water pressure, making the equipment float up more smoothly.

[0036] As Figures 2 to 3 shown, a first guiding plate 4 is fixedly connected to the bottom of the equipment main body 1. The first guiding plate 4 is V-shaped, and both sides of the first guiding plate 4 are fixedly connected with second guiding plates 5. The two second guiding plates 5 are triangular pyramids, and both of the two water storage buckets 3 are located in the enclosed space formed by the equipment main body 1, the first guiding plate 4 and the second guiding plates 5.

[0037] During operation: Through the provided guiding plate 1-4, during the diving process of the device main body 1, the guiding plate 1-4 will guide the device main body 1. The guiding plate 1-4 is V-shaped and will guide the water flow, thereby reducing the resistance when the device main body 1 dives. To a certain extent, it reduces the energy and power required for the device main body 1 to dive, increases the smoothness when the device main body 1 dives. By setting the guiding plate 2-5 with a triangular pyramid shape, when the device main body 1 travels in water, it reduces the resistance when the device main body 1 travels, reduces the lateral interference of the water flow when the device main body 1 travels, improves the overall performance of the device main body 1, facilitates its operation in more complex and harsher underwater environments, and a sealed space is formed between the device main body 1, the guiding plate 1-4 and the guiding plate 2-5, maintaining the integrity of the device shape and reducing the additional resistance caused by water flow scouring.

[0038] As Figures 4 to 5 shown, the suction and discharge assembly includes two inner pistons 1-6. The two inner pistons 1-6 are respectively located inside the water storage bucket 3 and are slidably connected to the inner wall of the water storage bucket 3. The tops of the two inner pistons 1-6 are fixedly connected with lifting rods 1-13. The outer walls of the lifting rods 1-13 are slidably connected to the inner wall of the device main body 1. A connecting piece 14 is fixedly connected between the two lifting rods 1-13. A connecting seat 15 is fixedly installed at the top of the device main body 1. A hydraulic cylinder 16 is fixedly installed at the bottom of the connecting seat 15. The output end of the hydraulic cylinder 16 is fixedly connected to the top of the connecting piece 14.

[0039] During operation: When the device main body 1 needs to dive, start the hydraulic cylinder 16. Its output end will drive the connecting piece 14 to rise. When the connecting piece 14 rises, it will drive the two lifting rods 1-13 to rise. When the lifting rods 1-13 rise, they will drive the inner pistons 1-6 to rise along the inner wall of the water storage bucket 3. When the inner pistons 1-6 rise along the inner wall of the water storage bucket 3, it will create a water inlet space at the bottom of the water storage bucket 3 and generate suction, facilitating the suction of seawater into the water storage bucket 3 to increase the total mass of the device main body 1. Similarly, when the device main body 1 needs to float, by controlling the hydraulic cylinder 16, the inner pistons 1-6 are made to descend along the inner wall of the water storage bucket 3, thereby discharging the seawater inside the water storage bucket 3, thus reducing the total mass of the device main body 1.

[0040] As Figures 4 to 6 shown, water pipes 7 are symmetrically and fixedly connected to the bottom of the water storage bucket 3. The outer walls of the water pipes 7 are inserted into the inner wall of the guiding plate 1-4. A plurality of fixing pieces 9 are fixedly connected to the outer wall of the guiding plate 1-4. The inner walls of the plurality of fixing pieces 9 are respectively fixedly connected to the outer walls of the plurality of water pipes 7. The ends of the water pipes 7 away from the water storage bucket 3 are fixedly connected to water chambers 10. Electric valves 8 are arranged outside the plurality of water pipes 7.

[0041] During operation: When the first inner piston 6 moves upward along the inner wall of the water storage barrel 3, multiple electric valves 8 are controlled to open. At this time, a suction force is generated when the first inner piston 6 moves upward. The suction force is conducted to the seawater through the water pipe 7 and the water chamber 10. After being affected by the suction force, the seawater enters the interior of the water storage barrel 3 through the water chamber 10 and the water pipe 7. Moreover, the higher the position where the first inner piston 6 rises, the greater the total mass of the seawater inhaled, resulting in a greater increase in the total mass of the equipment main body 1, and the greater the diving depth of the equipment main body 1. Similarly, when the first inner piston 6 moves downward and slides, the water inside the water storage barrel 3 will be squeezed out and discharged back into the water through the water pipe 7 and the water chamber 10.

[0042] As Figures 4 to 6 shown, a filter grille 11 is provided on one side of each of the multiple water chambers 10. The filter grilles 11 are all conical in shape. The outer diameter of one end of the water chamber 10 is smaller than the outer diameter of one end of the filter grille 11. Drainage plates 12 are fixedly connected to the outer walls of the multiple filter grilles 11, and one side of the drainage plate 12 is fixedly connected to the outer wall of the water chamber 10.

[0043] During operation: By providing a filter grille 11 on one side of the water chamber 10, impurities in the seawater are intercepted to prevent larger stones in the water from entering the interior of the water storage barrel 3 along with the seawater. During drainage, the stones cannot be completely discharged and may get stuck inside the water storage barrel 3 and the water pipe 7. Accumulation may block the interior of the water pipe 7 and the water storage barrel 3, resulting in a decrease in fluidity and affecting the total mass of the inhaled seawater. Moreover, since the filter grille 11 is conical in shape, the intercepted stones will flow along the surface of the filter grille 11 under the action of the suction force and be dispersed to various parts of the seawater through the drainage plate 12.

[0044] As Figures 8 to 10 shown, the charging and discharging assembly includes multiple air storage cylinders 19. The multiple air storage cylinders 19 correspond to multiple airbag pads 23 one by one. Inner pistons 21 are slidably connected to the inner walls of the air storage cylinders 19. Connecting air pipes 22 are fixedly communicated with the bottom sides of the air storage cylinders 19. One end of the connecting air pipe 22 away from the air storage cylinder 19 is fixedly communicated with one side of the airbag pad 23. A power assembly is provided above the inner piston 21, and the power assembly is used to drive the inner piston 21 to move up and down.

[0045] During operation: When the inner piston 6 moves upward along the inner wall of the water storage bucket 3, it will drive the inner piston 21 to move upward along the inner wall of the air storage cylinder 19 through the power assembly. In the initial state, the inside of the airbag pad 23 is filled with gas. When the inner piston 6 moves upward to absorb water, the inner piston 21 will move upward, and the gas inside the airbag pad 23 will be sucked into the inside of the air storage cylinder 19 through the connecting air pipe 22. After the gas inside the airbag pad 23 is sucked away, its volume will be compressed and reduced, so that the overall buoyancy received by the equipment main body 1 is reduced, facilitating the diving process of the equipment main body 1. Similarly, when the inner piston 6 moves upward along the inner wall of the water storage bucket 3, the inner piston 21 descends to refill the gas inside the air storage cylinder 19 into the inside of the airbag pad 23, making the gas inside the airbag pad 23 increase in volume and the overall buoyancy received by the equipment main body 1 increase, facilitating the floating process.

[0046] As Figure 4 and Figure 8 shown in the figure, the power assembly includes two T-shaped frames 17. On both sides of the bottom of the T-shaped frame 17, lifting rods II 18 are symmetrically and fixedly connected. One ends of the lifting rods II 18 are respectively fixedly connected to the top of the inner piston 21. The tops of the air storage cylinders 19 are fixedly connected with top plates 20. The lifting rods II 18 are slidably connected with the top plates 20. The bottom of the T-shaped frame 17 is fixedly connected to the top of the lifting rod I 13.

[0047] During operation: When the lifting rod I 13 drives the inner piston 6 to rise along the inner wall of the water storage bucket 3, it will drive the lifting rod II 18 to rise through the T-shaped frame 17. When the lifting rod II 18 rises, it will drive the inner piston 21 to rise along the inner wall of the air storage cylinder 19, thereby sucking the gas inside the airbag pad 23 into the inside of the air storage cylinder 19. Similarly, when the lifting rod I 13 drives the inner piston 6 to descend, the inner piston 21 descends to refill the gas inside the air storage cylinder 19 into the inside of the airbag pad 23.

[0048] As Figure 7 and Figure 8 shown in the figure, a controller 28 is fixedly installed on one side of the equipment main body 1. A steering ball 29 is arranged inside the controller 28. Steering fans 30 are symmetrically and fixedly connected to the outer wall of the steering ball 29. A traveling fan 33 is fixedly installed on the other side of the equipment main body 1.

[0049] During operation: When the equipment main body 1 dives to an appropriate depth through the suction and discharge assembly and the charging and discharging assembly, by controlling the blades inside the traveling fan 33 and the steering fans 30 to rotate, the equipment main body 1 can travel in water, and by controlling the controller 28 to control the rotation of the steering ball 29 inside it, the steering fans 30 on both sides can swing in one direction, so that the whole device can turn when traveling underwater, improving the flexibility of the whole device.

[0050] As Figure 2and Figure 7 As shown in Figure 7 , inner guard plates 24 are provided on the outsides of multiple airbag cushions 23. The inner guard plates 24 are fixedly installed on the top of the device main body 1, and the surfaces of the inner guard plates 24 are arc-shaped.

[0051] During operation: By providing the inner guard plates 24 outside the airbag cushions 23, the airbag cushions 23 are protected. And because the surfaces of the inner guard plates 24 are arc-shaped, the moving direction of the water flow is guided when the device main body 1 travels underwater, avoiding damage to the airbag cushions 23 caused by the pressure generated by the water flow when the device main body 1 travels underwater.

[0052] As Figure 1 and Figure 7 As shown in Figure 7 , outer guard plates 27 are symmetrically and fixedly connected to the sides of the device main body 1. One end of the outer guard plate 27 away from the device main body 1 is fixedly connected to a damping rod 26. Buffer springs 25 are provided outside the outer guard plates 27. Both ends of the buffer springs 25 are fixedly connected to the side of the device main body 1 and the side of the damping rod 26 respectively.

[0053] During operation: By providing the damping rod 26, and the damping rod 26 is buffered and shock-absorbed through the buffer springs 25 and the outer guard plates 27, effectively avoiding and protecting some devices on the top of the device main body 1 and the device main body 1 itself from being damaged by the impact of underwater organisms, resulting in damage to some devices.
