Description

Technical Field

[0001] The present invention relates to a counterweight device, in particular to an anti-tilt fixed counterweight device for an underwater acoustic monitoring device, belonging to the technical field of underwater target detection equipment. Background Art

[0002] With the development of marine technology and equipment, human activities at sea are becoming more and more frequent, and the demand for underwater target detection is also increasing.

[0003] Underwater target monitoring has been a very active research area in recent years. Traditional ship-based monitoring systems are bulky, complex to operate, and costly, making them unsuitable for long-term operations at sea. Small, portable underwater acoustic monitoring devices can complement larger acoustic detection systems and be deployed in large numbers on the seabed in key areas to achieve long-term, fixed-point monitoring. These devices can be used for tracking and protecting endangered marine mammals, locating, classifying, and tracking fish schools, salvaging and rescuing them, and detecting submarine pipelines.

[0004] When lowering the underwater acoustic monitoring device to the bottom of the water, the reefs on the bottom of the water are uneven. If the monitoring device is not counterweighted, it will be unstable when hit by external forces from underwater creatures. However, the increase in counterweight will increase the overall weight and increase the difficulty of recovery. After the underwater acoustic monitoring device is lowered to the bottom of the water, it needs to be marked and then salvaged one by one. The marks on the water surface are easily damaged and lost. Summary of the Invention

[0005] (1) Technical problems solved

[0006] The purpose of the present invention is to provide an anti-tilt fixed counterweight device for an underwater acoustic monitoring device in order to solve the above-mentioned problem, so as to solve the problem that the reefs on the bottom of the water are uneven. If the monitoring device is not counterweighted, it will be unstable when hit by external force from underwater organisms. However, the increase in counterweight will increase the overall weight and increase the difficulty of recovery. After the underwater acoustic monitoring device is lowered to the bottom of the water, it needs to be marked and subsequently salvaged one by one, and the marks on the water surface are easily damaged and lost.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-tilt fixed counterweight device for an underwater acoustic monitoring device, comprising a monitoring device, wherein the bottom of the monitoring device is fixedly connected to a box body, a buoyancy ring is sleeved on the outside of the box body, a telescopic rod is fixedly connected to the top of the buoyancy ring, a water distribution tank, a water pump and a storage pipe are provided at the bottom of the monitoring device, and the storage pipe is fixedly connected to a sealing valve and a solenoid valve. When the water pump fills the water distribution tank with water, a part of the water enters the storage pipe through the solenoid valve, and the water is dyed by the solid pigment inside the storage pipe and then discharged through the sealing valve, spraying brightly colored water onto the water surface to guide the work Personnel quickly move to the vicinity of the location where the monitoring equipment is about to float. The bottom of the box is provided with multiple sets of support structures, which are deployed at the bottom of the box to ensure that when the monitoring equipment and the box are supported on the bottom by the multiple sets of support structures, the space where the support structures are distributed is large enough to increase the distance between the support points of the support structures. One set of support structures includes a support rod, a push spring, a telescopic tube, a water pipe, a mobile vertical pipe, a water storage tank and a drain valve. A hydraulic cylinder and a mobile clamping plate are provided on one side of the support rod to ensure that the monitoring equipment can still sit stably on the bottom when the bottom is uneven, thereby ensuring the reliability of the monitoring equipment's underwater environment monitoring work. By lowering the center of gravity through multiple water storage tanks, the monitoring equipment can be prevented from being displaced by water flow and animals, ensuring that the monitoring equipment remains in the working position. The water pump is fixedly connected to the water inlet pipe, and a water control valve and a control valve are provided on the outside of the water inlet pipe.

[0009] Preferably, the monitoring equipment includes an acoustic pressure hydrophone, a data acquisition and storage module, a power supply module, a temperature sensor, a flow rate sensor, and a pressure sensor. Multiple groups of the support structures are distributed in a ring shape at the bottom of the box, and the water distribution tank and the water pump are fixedly connected to the inside of the box.

[0010] Preferably, the push spring is fixedly connected between the water distribution tank and the support rod, the telescopic tube is fixedly connected between the water distribution tank and the support rod, one end of the support rod is provided with a receiving slot, one end of the telescopic tube extends into the receiving slot, the other end of the support rod is provided with a receiving vertical slot, the irrigation pipe is arranged inside the receiving vertical slot, and is injected into the water storage tank through the telescopic tube, the irrigation pipe, and the movable vertical pipe, and a connecting elbow is fixedly connected between the irrigation pipe and the telescopic tube, so that the box body, multiple water storage tanks, and multiple movable vertical pipes are filled with water, so that the weight of the bottom of the monitoring equipment increases rapidly.

[0011] Preferably, the movable vertical pipe is fixedly connected to the top of the water tank, and the movable vertical pipe is sleeved on the outside of the water irrigation pipe. The movement of the movable vertical pipe is limited by a sealing ring to prevent the movable vertical pipe from being separated from the water irrigation pipe, thereby ensuring that the distance between the water tank and the box body can be changed while the water tank can be driven by the box body to float to the water surface. A sealing ring is fixedly sleeved on the bottom outside the water irrigation pipe, and the drain valve is fixedly connected to the bottom of the inner cavity of the water tank. When the drain valve is opened, the water tank is connected to the water area, and the water inside the water tank no longer exerts force on the monitoring equipment.

[0012] Preferably, the bottom of the box is provided with multiple sliding grooves and multiple storage grooves, the multiple storage grooves are respectively arranged on one side of the multiple sliding grooves, and the multiple support rods are respectively arranged inside the multiple sliding grooves. Under the limitation of the push spring and the telescopic tube, the support rod will not completely leave the sliding groove, ensuring a stable connection relationship between the support rod and the box, and the support rod is set to be L-shaped.

[0013] Preferably, a drag reduction plate is fixedly connected to the top of the buoyancy ring, and the drag reduction plate is sleeved on the outside of the box. One end of the telescopic rod passes through the drag reduction plate and is fixedly connected to the monitoring equipment. The drag reduction plate reduces the resistance of the buoyancy ring to floating, and the movement of the drag reduction plate and the buoyancy ring is limited by the setting of the telescopic rod, thereby reducing the friction generated between the buoyancy ring and the box. The buoyancy ring is set on the outside of multiple support rods.

[0014] Preferably, the hydraulic cylinder is fixedly connected to one side of the support rod, and one end of the hydraulic cylinder is fixedly connected to a T-shaped plate. The hydraulic cylinder drives the movable card plate to move through the T-shaped plate. The movable movable card plate is inserted into the limiting slot under the limit of the guide shaft. One side of the T-shaped plate is fixedly connected to the movable card plate, and the support rod is provided with a limiting slot. The movable card plate passes through the limiting slot and is clamped on the support rod, so as to limit the position between the movable vertical pipe and the support rod, so that the water tank and the monitoring equipment cannot move.

[0015] Preferably, the support rod is fixedly connected to a guide shaft, a limiting groove is provided on the top of the movable card plate, and the hydraulic cylinder drives the movable card plate to move through the T-shaped plate. The movable card plate is limited by the guide shaft and is inserted into the limiting groove and rubs against the movable vertical pipe. The guide shaft is arranged inside the limiting groove to completely limit the monitoring equipment.

[0016] Preferably, the water control valve is fixedly connected to one end of the water inlet pipe, and a water pump is fixedly connected between the control valve and the water inlet pipe. The water pump pumps water into the water storage tank through the water inlet pipe and the water control valve. The control valve is arranged at the bottom of the inner cavity of the box, and the water can fill the inside of the box, thereby increasing the weight of the box and acting as a counterweight.

[0017] Preferably, the storage tube is fixedly connected to the bottom of the water distribution tank, one end of the solenoid valve extends into the interior of the water distribution tank and is fixedly connected to the water distribution tank, and the sealing valve is fixedly connected to the top of the storage tube on the side away from the water distribution tank. The water is dyed by the solid pigment inside the storage tube and then discharged through the sealing valve, spraying brightly colored water onto the water surface to guide the staff to quickly move to the vicinity of the position where the monitoring equipment is about to float.

[0018] The present invention provides an anti-tilt fixed counterweight device for an underwater acoustic monitoring device, which has the following beneficial effects:

[0019] This underwater acoustic monitoring device features an anti-tilt fixed counterweight mechanism. The pump pumps water from the tank through an inlet pipe, a pumping pipe, and a control valve, draining the water inside to provide buoyancy. The drain valve opens the water tank, connecting it to the water. The water inside the tank no longer exerts force on the monitoring device, allowing the counterweight at the bottom of the device to be removed. The discharged water then sprays toward the bottom of the water, creating a reaction force on the monitoring device and the tank. As the monitoring device and the tank rise, the resulting water flow causes the water surface to roll, acting as a positioning mechanism. This allows the monitoring device to be lifted by the drained tank, ensuring rapid and effortless recovery. Furthermore, as the pump fills the water distribution tank, some water enters the storage tube through a solenoid valve. This water is then dyed by the solid pigment inside the tube and discharged through a sealed valve, spraying brightly colored water onto the surface of the water, guiding personnel to quickly move to the location where the monitoring device is about to float, thereby accelerating recovery.

[0020] 2. The underwater acoustic monitoring device features a fixed counterweight to prevent tilt. The monitoring device and housing push the support rod and water pipe toward the water tank until the water tank closest to the horizontal plane provides support for the support rod's movement. At this point, the monitoring device is restrained by the housing and the multiple water-filled tanks, preventing it from tilting. The multiple water tanks also support and limit the monitoring device, ensuring it remains stable even when the bottom is uneven, ensuring reliable underwater environmental monitoring. The multiple water tanks lower the center of gravity, preventing the monitoring device from being displaced by currents and animals, ensuring it remains in its working position.

[0021] 3. The underwater acoustic monitoring device's anti-tilt fixed counterweight device operates as a pump that pumps water through the water inlet pipe and water control valve, then pumps it into the water tank via a telescopic tube, water filling pipe, and mobile riser. Simultaneously, the water inlet pipe connects to the interior of the tank via a pumping pipe and a control valve. Therefore, water flowing through the inlet pipe enters the tank through the pumping pipe and control valve, filling the tank, multiple water tanks, and multiple mobile risers with water. This rapidly increases the weight of the monitoring device's bottom, causing it to sink rapidly to the bottom of the water, driven by the tank, multiple water tanks, and multiple mobile risers.

[0022] 4. The underwater acoustic monitoring device has an anti-tilt fixed counterweight device. When one side of the multiple support structures loses its limit, the multiple support structures are deployed at the bottom of the box to ensure that when the monitoring equipment and the box are supported on the bottom of the water by the multiple support structures, the space where the support structures are distributed is large enough, increasing the distance between the support points of the support structures to ensure the stability of the monitoring equipment and the box.

[0023] 5. The underwater acoustic monitoring device is equipped with an anti-tilt fixed counterweight device. The water pump continuously discharges water through the drain valve and sprays it to the bottom of the water, providing buoyancy for the monitoring equipment. In addition, water continuously flows through the storage tube, and the dyed water can be sprayed to the water surface. Even if the monitoring equipment cannot float to the water surface, the staff can determine the approximate position of the monitoring equipment according to the movement of the dyed water, which is convenient for the recovery and salvage of the monitoring equipment, and can ensure the probability of successful recovery and salvage of the monitoring equipment.

[0024] 6. The underwater acoustic monitoring device is equipped with an anti-tilt fixed counterweight device. After the water pump draws water through the water inlet pipe and the water control valve, the water is only pumped into the water storage tank through the water distribution tank, the telescopic pipe, and the mobile vertical pipe. This makes the water storage tank have a certain weight, limits the position of the monitoring equipment, increases the difficulty of the monitoring equipment floating and moving, prevents the monitoring equipment from drifting away from its original position due to the approach of staff, and reduces the difficulty of recovering the monitoring equipment.

[0025] 7. The underwater acoustic monitoring device features an anti-tilt fixed counterweight device. The working hydraulic cylinder drives the movable card plate through a T-shaped plate. The movable card plate, limited by the guide shaft, is inserted into the limit slot and rubs against the movable vertical pipe. At the same time, the movable card plate passes through the limit slot and is clamped on the support rod, thus limiting the position between the movable vertical pipe and the support rod, preventing the water tank and monitoring equipment from moving. This can completely limit the position of the monitoring equipment, meet the needs of monitoring equipment for monitoring the underwater environment in waters with high water flow rates, ensure the stability of the monitoring equipment, and avoid errors in monitoring results caused by movement of the monitoring equipment.

[0026] 8. The underwater acoustic monitoring device is equipped with an anti-tilt fixed counterweight device. When the monitoring equipment floats to the surface of the water, the water pump works and the drain valve is closed. After the water pump draws water through the water inlet pipe and the water control valve, it is only pumped into the water storage tank through the water distribution tank, the telescopic pipe, and the mobile vertical pipe. This makes the water storage tank have a certain weight, which limits the position of the monitoring equipment, increases the difficulty of floating and moving the monitoring equipment, and prevents the monitoring equipment from drifting away from its original position due to the approach of staff, thereby reducing the difficulty of recovering the monitoring equipment.

[0042] An embodiment of the present invention provides an anti-tilt fixed counterweight device for an underwater acoustic monitoring device.

[0043] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 , including a monitoring device 1, the bottom of the monitoring device 1 is fixedly connected to a box 2, the monitoring device 1 includes an acoustic pressure hydrophone, a data acquisition and storage module, a power supply module, a temperature sensor, a flow rate sensor, and a pressure sensor. Multiple groups of support structures are distributed in a ring at the bottom of the box 2. The water distribution tank 22 and the water pump 23 are fixedly connected to the inside of the box 2. The outer side of the box 2 is provided with a buoyancy ring 4, and the top of the buoyancy ring 4 is fixedly connected to a telescopic rod 5. The bottom of the monitoring device 1 is provided with a water distribution tank 22, a water pump 23 and a storage pipe 28, the storage tube 28 is fixedly connected with a sealing valve 29 and a solenoid valve 30. Multiple groups of supporting structures are provided at the bottom of the box body 2. One group of supporting structures includes a support rod 8, a push spring 9, a telescopic tube 10, a water irrigation pipe 13, a movable vertical pipe 14, a water storage tank 15 and a drain valve 16. A hydraulic cylinder 20 and a movable card plate 18 are provided on one side of the support rod 8. The support rod 8 is provided with a limit card slot 32. The water pump 23 is fixedly connected with the water inlet pipe 24. The water control valve 25 and the control valve 27 are provided on the outside of the water inlet pipe 24.

[0044] Specifically, the monitoring device 1 includes an acoustic pressure hydrophone, a data acquisition and storage module, a power supply module, a temperature sensor, a flow rate sensor, and a pressure sensor. When the monitoring device 1 sinks to the bottom of the water, the acoustic pressure hydrophone receives acoustic signals from the water, which are then processed and stored within the data acquisition and storage module. The power supply module provides power to the various electrical components, and the temperature sensor, flow rate sensor, and pressure sensor collect changes in temperature, flow rate, and pressure at the bottom of the water to monitor the underwater hydrological environment. It should also be noted that the control of electrical equipment such as the drain valve 16, the water pump 23, the water control valve 25, the control valve 27, the sealing valve 29, and the solenoid valve 30 can be achieved by using existing technologies such as numerical control programs and PLC control programs installed within the monitoring device.

[0045] After the monitoring device 1 and the box 2 are placed on the water surface, the buoyancy ring 4 moves under the action of the buoyancy of the water, causing one side of the multiple groups of support structures to lose their limit, and the multiple groups of support structures are unfolded at the bottom of the box 2, ensuring that when the monitoring device 1 and the box 2 are supported by the multiple groups of support structures on the bottom of the water, the space where the support structures are distributed is large enough, increasing the distance between the support points of the support structures, and ensuring the stability of the monitoring device 1 and the box 2.

[0046] After the monitoring device 1 and housing 2 float to the surface, the pump 23 is activated. The multiple support structures, each comprising a telescopic tube 10, a water supply pipe 13, a mobile standpipe 14, and a water storage tank 15, are activated. The pump 23 pumps water through the inlet pipe 24 and a water control valve 25, and then pumps water into the water storage tank 15 via the telescopic tube 10, the water supply pipe 13, and the mobile standpipe 14. Simultaneously, the inlet pipe 24 communicates with the interior of the housing 2 via a pumping pipe 26 and a control valve 27. Water flowing within the inlet pipe 24 enters the housing 2 through the pumping pipe 26 and the control valve 27, filling the housing 2, the multiple water storage tanks 15, and the multiple mobile standpipes 14 with water. This rapidly increases the weight of the bottom of the monitoring device 1, and the monitoring device 1 sinks rapidly to the bottom of the water, driven by the housing 2, the multiple water storage tanks 15, and the multiple mobile standpipes 14.

[0047] When the multiple water tanks 15 sink and touch the bottom, the movable vertical pipes 14 fixed to the multiple water tanks 15 can slide on the outside of the water pipe 13. Therefore, even if the multiple water tanks 15 stay at different positions from the horizontal plane, the monitoring device 1 and the box body 2 will push the support rod 8 and the water pipe 13 to move toward the water tank 15 until the water tank 15 closest to the horizontal plane limits the movement of the support rod 8. At this time, the monitoring device 1 is limited by the box body 2 and the multiple water tanks 15 filled with water and cannot tilt. The monitoring device 1 is supported and limited by the multiple water tanks 15, ensuring that the monitoring device can still sit stably on the bottom when the bottom of the water is uneven, ensuring the reliability of the monitoring device's monitoring of the underwater environment. By lowering the center of gravity through the multiple water tanks 15, the monitoring device 1 can be prevented from being displaced by the influence of water flow and animals, ensuring that the monitoring device 1 stays in the working position.

[0048] When a recovery command is sent to monitoring device 1, pump 23 operates, while solenoid valve 30 opens, sealing valve 29 opens, water control valve 25 closes, and drain valve 16 opens. After water control valve 25 closes, water inlet pipe 24 is disconnected from the outside world. Pump 23 operates, pumping water from inside housing 2 through inlet pipe 24, pumping pipe 26, and control valve 27, discharging water through water distribution tank 22, telescopic tube 10, movable standpipe 14, water storage tank 15, and drain valve 16. At this point, drain valve 16 opens, connecting water storage tank 15 to the water area. The water inside tank 15 no longer exerts force on monitoring device 1. Furthermore, the water discharged from drain valve 16 sprays toward the bottom of the water, exerting a reaction force on monitoring device 1 and housing 2. This force causes the water flow generated when monitoring device 1 and housing 2 float upward, causing the water surface to roll, acting as a positioning mechanism. This allows monitoring device 1 to float, driven by the drained housing 2, ensuring a quick and effortless recovery of monitoring device 1. And when the water pump 23 fills the water distribution tank 22 with water, a part of the water enters the storage tube 28 through the solenoid valve 30. The water is dyed by the solid pigment inside the storage tube 28 and is discharged through the sealing valve 29, spraying brightly colored water onto the water surface, guiding the staff to quickly move to the vicinity of the position where the monitoring equipment 1 is about to float, which can increase the speed of recovering the monitoring equipment 1.

[0049] After the water pump 23 has operated for a period of time, the water inside the housing 2 is drained. After this period of time, the water control valve 25 automatically opens and the control valve 27 automatically closes. At this time, the water pump 23 continues to drain water through the drain valve 16 and sprays it toward the bottom of the water, providing buoyancy for the monitoring device 1. Furthermore, water continues to flow through the storage pipe 28, spraying the dyed water toward the surface of the water. Even if the monitoring device 1 cannot float to the surface, the staff can determine the approximate location of the monitoring device 1 based on the movement of the dyed water, facilitating the recovery and salvage of the monitoring device 1 and ensuring the success rate of the recovery and salvage.

[0050] When the monitoring device 1 floats to the surface of the water, the water pump 23 works and the drain valve 16 is closed. After the water pump 23 pumps water through the water inlet pipe 24 and the water control valve 25, the water is only pumped into the water storage tank 15 through the water distribution tank 22, the telescopic tube 10, and the movable vertical pipe 14, so that the water storage tank 15 has a certain weight, which limits the position of the monitoring device 1, increases the difficulty of floating and moving the monitoring device 1, prevents the monitoring device 1 from drifting away from its original position due to the approach of the staff, and reduces the difficulty of recovering the monitoring device 1.

[0051] Please refer again Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9The push spring 9 is fixedly connected between the water distribution box 22 and the support rod 8, the telescopic tube 10 is fixedly connected between the water distribution box 22 and the support rod 8, one end of the support rod 8 is provided with a receiving slot 11, one end of the telescopic tube 10 extends into the receiving slot 11, and the other end of the support rod 8 is provided with a receiving vertical slot 31. The irrigation pipe 13 is arranged inside the receiving vertical slot 31, and a connecting elbow 12 is fixedly connected between the irrigation pipe 13 and the telescopic tube 10. The movable vertical pipe 14 is fixedly connected to the top of the water storage tank 15, and the movable vertical pipe 14 is sleeved on the outside of the irrigation pipe 13. The bottom of the outer side of the irrigation pipe 13 is fixedly sleeved with a sealing ring 17, and the drain valve 16 is fixedly connected to the bottom of the inner cavity of the water storage tank 15. A plurality of sliding grooves 6 and a plurality of receiving slots 7 are provided at the bottom of the box body 2. The plurality of receiving slots 7 are respectively arranged on one side of the plurality of sliding slots 6, and the plurality of support rods 8 are respectively arranged inside the plurality of sliding slots 6, and the support rod 8 is arranged in an L shape.

[0052] Specifically, when the buoyancy ring 4 floats, one end of the support rod 8 loses the restraint of the buoyancy ring 4, and only a very small area of ​​the bend of the support rod 8 contacts the buoyancy ring 4. Therefore, the friction between the buoyancy ring 4 and the support rod 8 will not affect the floating of the buoyancy ring 4. When the support rod 8 loses the restraint, the rebounding push spring 9 pushes the support rod 8 to move to a position away from the water distribution tank 22, and a telescopic tube 10 with telescopic properties is fixedly connected between the support rod 8 and the water distribution tank 22, so the support rod 8 can move. In addition, the push spring 9 and the telescopic tube 10 both have telescopic limits. Therefore, under the restraint of the push spring 9 and the telescopic tube 10, the support rod 8 will not completely leave the interior of the sliding groove 6, ensuring a stable connection between the support rod 8 and the box body 2.

[0053] The plurality of push springs 9 push the plurality of annularly distributed support rods 8 to move away from the water distribution tank 22, thereby increasing the distribution range of the support points at the bottom of the monitoring device 1 and ensuring the stability of the monitoring device 1 supported by the plurality of support structures.

[0054] In addition, the movable vertical pipe 14 fixed to the water storage tank 15 is sleeved on the outside of the water irrigation pipe 13, and a sealing ring 17 is fixed on the outside of the water irrigation pipe 13. The sealing ring 17 limits the movement of the movable vertical pipe 14 to prevent the movable vertical pipe 14 from being separated from the water irrigation pipe 13, ensuring that the distance between the water storage tank 15 and the box body 2 can be changed while ensuring that the water storage tank 15 can be driven by the box body 2 to float to the water surface.

[0055] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 10The top of the buoyancy ring 4 is fixedly connected to the drag reduction plate 3, and the drag reduction plate 3 is sleeved on the outside of the box body 2. One end of the telescopic rod 5 passes through the drag reduction plate 3 and is fixedly connected to the monitoring equipment 1. The buoyancy ring 4 is arranged on the outside of multiple support rods 8, and the hydraulic cylinder 20 is fixedly connected to one side of the support rod 8. One end of the hydraulic cylinder 20 is fixedly connected to a T-shaped plate 21, and one side of the T-shaped plate 21 is fixedly connected to the movable card plate 18. The support rod 8 is fixedly connected to a guide shaft 19. A limiting groove is provided on the top of the movable card plate 18, and the guide shaft 19 is arranged inside the limiting groove.

[0056] Specifically, after the monitoring device 1 stops moving, the hydraulic cylinder 20 fixed to the support rod 8 starts working. The working hydraulic cylinder 20 drives the movable clamping plate 18 to move through the T-shaped plate 21. The movable clamping plate 18 is limited by the guide shaft 19 and inserted into the limiting groove 32, and then rubs against the movable vertical pipe 14. At the same time, the movable clamping plate 18 passes through the limiting groove 32 and is clamped on the support rod 8, thereby limiting the position between the movable vertical pipe 14 and the support rod 8, so that the water storage tank 15 and the monitoring device 1 cannot move. In this way, the monitoring device 1 is completely limited, meeting the needs of the monitoring device 1 to monitor the underwater environment in water areas with high water flow rates, ensuring the stable operation of the monitoring device 1, and avoiding errors in the monitoring results caused by the movement of the monitoring device 1.

[0057] A drag reduction plate 3 is fixedly connected to the top of the buoyancy ring 4 to reduce the floating resistance of the buoyancy ring 4. The telescopic rod 5 is set to limit the movement of the drag reduction plate 3 and the buoyancy ring 4 to reduce the friction between the buoyancy ring 4 and the box 2.

[0058] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 12 and Figure 13 The water control valve 25 is fixedly connected to one end of the water inlet pipe 24, and a water pumping pipe 26 is fixedly connected between the control valve 27 and the water inlet pipe 24. The control valve 27 is arranged at the bottom of the inner cavity of the box body 2, and the storage pipe 28 is fixedly connected to the bottom of the water distribution tank 22. One end of the solenoid valve 30 extends into the interior of the water distribution tank 22 and is fixedly connected to the water distribution tank 22. The sealing valve 29 is fixedly connected to the top of the storage pipe 28 away from the side of the water distribution tank 22.

[0059] Specifically, when the water pump 23 is operating, if the water control valve 25 and the control valve 27 are simultaneously opened, the water pump 23 can pump water into the water storage tank 15 through the water inlet pipe 24 and the water control valve 25. At this time, the water inlet pipe 24 is connected to the interior of the tank 2 through the water pumping pipe 26 and the control valve 27, so that water can be poured into the tank 2. Under the action of the external water pressure, the water can fill the tank 2. When the water pump 23 is operating and the water control valve 25 is closed, and the control valve 27 is opened, the operating water pump 23 draws water out of the tank 2 through the water inlet pipe 24, the water pumping pipe 26, and the control valve 27, evacuating the interior of the tank 2, so that the tank 2 provides buoyancy for the monitoring device 1, causing the monitoring device 1 to float under the action of the tank 2.
