Description

Technical Field

[0001] The present application relates to the technical field of monitoring devices, and in particular to a bottom-mounted sea current and wave monitoring device. Background Art

[0002] At present, with the increasing changes in the global climate and the growing importance of marine environmental protection, marine environmental monitoring technology has become the key to scientific research and environmental protection. The measurement of wave parameters such as wave height, wave direction, wave period, wavelength, and wave speed has extremely important significance and application value for marine engineering construction, marine fishery production, marine transportation, marine environmental protection, marine scientific research, and even marine national defense. In the prior art, for the related technology of monitoring devices, a Chinese patent with the publication number CN208474863U discloses a bottom-mounted wave monitoring system, including a device main body. A top plate is fixedly installed at the top of the device main body. A threaded shaft is fixedly installed at the top end of the support. A motor is fixedly installed inside the power box. A wireless connection device is fixedly installed at the top end of the motor. A threaded lead screw is installed between the sealing gaskets. A power supply device is fixedly installed at the center inside the base. Fixing nails are fixedly installed at both ends of the bottom of the nut. Fixing seats are fixedly installed at both ends of the base. By installing a lead screw and a nut at the bottom of the device main body and installing fixing nails at the bottom end of the nut in the present utility model, the nut can be used to move downward along the lead screw, so that the fixing nails are inserted into the soil layer at the bottom of the sea, fixing the monitoring device at the bottom of the water and monitoring the waves. At the same time, by installing right-angled trapezoidal fixing seats at both ends of the base, the weight of the bottom can be increased by using the fixing seats to prevent the monitoring device from tipping over at the bottom of the water.

[0003] During the detection process, the bottom-mounted sea current and wave monitoring device is often interfered by sediment and debris on the seabed, thus affecting the detection accuracy. At present, the bottom-mounted sea current and wave monitoring device often does not have the function of self-cleaning or can only provide a single driving method for self-cleaning, which increases the load on the power supply. Secondly, during the installation process from the sea surface to the seabed, it is easily affected by the sea current, causing the device to tilt and fall to the seabed, thus affecting the detection. Summary of the Invention

[0004] The purpose of the present application is to provide a bottom-mounted sea current and wave monitoring device.

[0005] In the first aspect, the bottom-mounted sea current and wave monitoring device provided by the present application adopts the following technical solutions: Bottom-mounted sea current and wave monitoring device, including a chassis, at the center of the top of the chassis is connected a sealed chamber, at the top of the sealed chamber is connected a detection probe, the detection probe is arc-shaped, the detection end of the detection probe extends to the outer wall of the sealed chamber, at the bottom of the detection probe is connected a partition plate, the outer wall of the partition plate is fixedly connected to the inner wall of the sealed chamber, at the middle of the bottom end of the partition plate is connected a fixing frame, at the middle of the bottom end of the fixing frame is connected a central shaft through a bearing, on the outer wall of the bottom of the central shaft is connected a first bevel gear, at the center of the top of the fixing frame is connected a servo motor, the output end of the servo motor is connected to the central shaft, the servo motor drives the central shaft to rotate, the rotation of the central shaft drives the first bevel gear to rotate synchronously, on both sides of the first bevel gear are provided rotating rods, both groups of rotating rods are connected to the inner wall of the sealed chamber through bearings, at the outer wall of the end of the rotating rod close to the first bevel gear is connected a second bevel gear, the second bevel gear meshes with the first bevel gear, at the end of both groups of rotating rods away from the second bevel gear passes through the sealed chamber and is connected with a gear, and at the connection between the rotating rod and the sealed chamber is provided a sealing ring.

[0006] By adopting the above technical solution, the chassis is pyramid-shaped and plays a role in connecting and fixing. The sealed chamber plays a sealing role. The detection probe is a Doppler current meter. The arc design of the detection probe can reduce the water flow resistance and expand the sensing coverage range. It cooperates with the cleaning brush driven by the crown gear to achieve 360-degree dead-angle-free cleaning. It is fixed and partitioned by the partition plate. The servo motor can drive the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gears on both sides to move in opposite directions, thereby driving the two groups of rotating rods to move synchronously in opposite directions. The rotation of the rotating rods drives the gears to rotate synchronously, thus realizing the drive of the subsequent cleaning brush.

[0007] Around the outer wall of the top of the sealed chamber is provided an annular track, on the outer wall of the annular track is sleeved a rotating ring, the rotating ring is movably connected with the annular track, at the outer wall of the bottom of the rotating ring is connected a crown gear, the crown gear meshes with the two groups of gears, at both sides of the top of the rotating ring are connected connecting arms, on the side wall of both groups of connecting arms close to the detection probe are connected cleaning brushes, and the cleaning brushes are in contact with the detection probe.

[0008] By adopting the above technical solution, the rotating ring can rotate on the outer wall of the ring track. When the servo motor drives the two groups of gears to rotate in opposite directions, the crown gear is driven to rotate through the meshing of the gears and the crown gear. The rotation of the crown gear drives the rotating ring to rotate synchronously. The rotation of the rotating ring can drive the connecting arm to rotate synchronously, thereby driving the cleaning brush to rotate on the outer wall of the detection probe to automatically clean the detection probe, reducing the interference of submarine sediment and sundries on the device, and continuously cleaning to ensure that the equipment is always in the best working state during long-term deployment.

[0009] A speed reducer is provided on the outer wall of one side of the sealed chamber. The end of one rotating rod is connected to the output shaft of the speed reducer through a coupling. The input shaft of the speed reducer is connected to a drive shaft, and a guide vane turbine is connected to the outer wall of the drive shaft.

[0010] By adopting the above technical solution, the guide vane turbine adopts a NACA airfoil turbine to reduce turbulent losses. Microelectrodes are embedded on the blade surface to electrolyze hypochlorous acid to inhibit barnacle attachment. A grid guard is installed around the guide vane turbine with a spacing of 5 mm to block large seaweeds or floating objects from entering. The guide vane turbine can be driven to rotate by the undersea current. The rotation of the guide vane turbine drives the drive shaft to rotate synchronously. After the drive shaft is decelerated by the speed reducer, it drives the rotating rod to rotate, thereby driving the gear on one side to rotate. The rotation of the gear can drive the cleaning brush to rotate and clean, so as to realize the cleaning work of the detection probe without power output. When the undersea current velocity is relatively large, the detection probe can be cleaned without the drive of the servo motor. When the undersea current velocity is relatively small, the servo motor can be used to assist the rotation of the guide vane turbine to drive the cleaning, thus achieving the energy-saving effect, reducing the load on the mobile power supply when driving the cleaning brush to clean, and extending the service life of the mobile power supply under the sea.

[0011] A wave gauge is provided on the outer wall of one side of the sealed chamber. A control component is provided in the middle of the sealed chamber. The control component includes an acquisition memory, a communication unit, and a Beidou positioning module. The communication unit is provided on one side of the acquisition memory, and the Beidou positioning module is provided on one side of the communication unit. The control component is electrically connected to the wave gauge and the detection probe. A mobile power supply is provided at the bottom of the control component.

[0012] By adopting the above technical solution, the wave meter uses the Nortek AWAC acoustic Doppler profiler, which can synchronously measure the flow velocity, wave height and direction. The acquisition memory in the control component can store the data detected by the detection probe and the wave meter for uploading after the working cycle. The Beidou positioning module and communication unit enable the offshore staff to establish a data connection with the device and accurately know the specific location of the device. The mobile power supply uses a high-energy-density lithium battery lithium thionyl chloride battery, which can ensure that the device can carry out long-term continuous detection work on the seabed.

[0013] The bottom end of the base frame is connected with a counterweight block, the tops of the four ends of the base frame are connected with a waterproof shell, the interiors of multiple groups of the waterproof shells are fixedly connected with a dual-axis motor, the top outer wall of the waterproof shell is connected with a rotating shaft through a bearing, the top output end of the dual-axis motor is connected to the rotating shaft, and the outer wall of the rotating shaft is connected with a spiral blade.

[0014] By adopting the above technical scheme, the gravity at the bottom of the chassis can be increased by the counterweight block, so that the chassis can always maintain a stable fall at the bottom position during the launch of the device, thereby improving the stability of the device. The waterproof shell plays a waterproof role to prevent water from entering the dual-axis motor. The dual-axis motor is specifically a dual-rotor motor. The two axes are driven completely independently and can operate simultaneously or in time-sharing. In the process of putting the device into the sea, the device is easily tilted by the factors of ocean currents, which can easily affect the direction of the detection probe when the device falls to the seabed. During the falling process, when the tilt angle of the chassis is too large, one or more sets of dual-axis motors can be used to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the spiral blades to rotate. A set of spiral blades generates a downward thrust or an upward lift on a single side of the chassis, thereby adjusting the device as a whole so that it can ensure that the detection probe sits on the bottom in an upward direction, thereby improving the stability of the device.

[0015] Movable grooves are provided at the bottom of the four ends of the base frame, the top inner wall of the movable groove is connected with a screw rod through a bearing, the bottom output end of the dual-axis motor is connected to the screw rod, the bottom outer wall of the screw rod is threadedly connected with a threaded barrel, the bottom end of the threaded barrel is connected with a moving block, strip grooves are provided on the inner walls on both sides of the middle part of the movable groove, and the outer walls on both sides of the moving block are connected with sliders, and the sliders are embedded in the strip grooves.

[0016] By adopting the above technical solution, the movable groove plays a limiting role, and the bottom output end of the dual-axis motor can drive the screw to rotate. The rotation of the screw drives the threaded barrel to move up and down, and the lifting and lowering of the threaded barrel drives the moving block to move up and down synchronously. The slider is embedded in the strip groove to play a limiting role to prevent the threaded barrel from rotating synchronously with the screw. The helix angle between the screw and the threaded barrel is smaller than the friction angle, and it has self-locking properties.

[0017] The bottom end of the moving block is connected to a lead screw through a bearing. The inner wall of the bottom of the movable groove is fixedly connected to an internally threaded block. The lead screw is engaged with the internally threaded block. The bottom end of the lead screw is connected to a spike portion.

[0018] By adopting the above technical solution, when the moving block moves, it can drive the lead screw to move synchronously, so that the spike portion can be pushed into the sediment at the bottom of the sea. At the same time, the lead screw is engaged with the internally threaded block, so that the lead screw rotates while descending, and thus rotates into the seabed ground, improving the stability of the device. The helix angle between the lead screw and the internally threaded block is greater than the friction angle and does not have self-locking. At the same time, during the drilling process of the spike portion, the double-shaft motor can be driven to drive the spiral blade to rotate, so as to increase the downward pressure of the device and avoid difficult drilling.

[0019] One side inner wall of the sealed chamber is connected to a horizontal sensor. A controller is arranged at the bottom end of the horizontal sensor. A lifting ring is arranged on one outer wall of the chassis.

[0020] By adopting the above technical solution, the horizontal angle of the device can be detected by the horizontal sensor, so as to adjust the level through the spiral blade. The controller plays a control role. Through the lifting ring, it can be connected to a rope so that after the device system completes a monitoring cycle, the system can be taken out of the water and the data can be exported.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The seabed ocean current can drive the guide turbine to rotate. The rotation of the guide turbine drives the drive shaft to rotate synchronously. After the drive shaft is decelerated by a reducer, it drives the rotating rod to rotate, thereby driving the gear on one side to rotate. The rotation of the gear can drive the cleaning brush to rotate and clean, so as to realize the cleaning work of the detection probe without power output. When the seabed ocean current velocity is relatively large, the cleaning of the detection probe can be realized without the drive of a servo motor. When the seabed ocean current velocity is relatively small, the servo motor can be used to assist the rotation of the guide turbine to drive the cleaning, thus realizing the energy-saving effect, reducing the load on the mobile power supply when driving the cleaning brush to clean, and increasing the service life of the mobile power supply on the seabed; 2. During the process of deploying the device into the sea, the device is vulnerable to the influence of ocean currents and may tilt, which can easily affect the orientation of the detection probe when the device falls to the seabed. When the tilt angle of the chassis is too large during the falling process, one or more sets of dual-axis motors can be driven to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the spiral blade to rotate. By a set of spiral blades, a downward thrust or an upward lift is generated on a single side of the chassis, thereby adjusting the overall device to ensure that the detection probe sits on the seabed with the upward direction, improving the stability of the device. At the same time, during the drilling process of the spike part, the dual-axis motor can be driven to drive the spiral blade to rotate, thereby increasing the downward pressure of the device and avoiding difficult drilling.

[0023] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 6 , drawings, and drawings.

At the top of the sealed chamber 2, a detection probe 3 is connected. The detection probe 3 is arc-shaped, and the detection end of the detection probe 3 extends to the outer wall of the sealed chamber 2. At the bottom of the detection probe 3, a partition plate 4 is connected. The outer wall of the partition plate 4 is fixedly connected to the inner wall of the sealed chamber 2. At the middle of the bottom end of the partition plate 4, a fixing frame 5 is connected. At the middle of the bottom end of the fixing frame 5, a central shaft 6 is connected through a bearing. On the bottom outer wall of the central shaft 6, a first bevel gear 7 is connected. At the center of the top of the fixing frame 5, a servo motor 8 is connected. The output end of the servo motor 8 is connected to the central shaft 6. The servo motor 8 drives the central shaft 6 to rotate. The rotation of the central shaft 6 drives the first bevel gear 7 to rotate synchronously. On both sides of the first bevel gear 7, a rotating rod 9 is arranged. Both groups of rotating rods 9 are connected to the inner wall of the sealed chamber 2 through bearings. At the outer wall of the end of the rotating rod 9 close to the first bevel gear 7, a second bevel gear 10 is connected. The second bevel gear 10 meshes with the first bevel gear 7. At the end of both groups of rotating rods 9 away from the second bevel gear 10, a gear 11 is connected after passing through the sealed chamber 2. At the connection between the rotating rod 9 and the sealed chamber 2, a sealing ring 111 is arranged. The bottom frame 1 is pyramid-shaped and serves to connect and fix. The sealed chamber 2 serves as a seal. The detection probe 3 is a Doppler current meter. The arc design of the detection probe 3 can reduce the water flow resistance and expand the sensing coverage range. It cooperates with the cleaning brush 16 driven by the crown gear 14 to achieve 360-degree dead-angle-free cleaning. It is fixed and partitioned by the partition plate 4. Through the servo motor 8, the first bevel gear 7 can be driven to rotate. The rotation of the first bevel gear 7 drives the two second bevel gears 10 on both sides to move in opposite directions, thereby driving the two groups of rotating rods 9 to move in the same reverse direction synchronously. The rotation of the rotating rod 9 drives the gear 11 to rotate synchronously, thereby realizing the drive of the subsequent cleaning brush 16.

[0025] The outer wall of the top of the sealed chamber 2 is surrounded by a ring rail 12. A rotating ring 13 is sleeved on the outer wall of the ring rail 12. The rotating ring 13 is movably connected to the ring rail 12. A crown gear 14 is connected to the outer wall of the bottom of the rotating ring 13. The crown gear 14 meshes with two groups of gears 11. Both sides of the top outer wall of the rotating ring 13 are connected with connecting arms 15. Cleaning brushes 16 are connected to the side walls of the two connecting arms 15 close to the detection probe 3. The cleaning brushes 16 are in contact with the detection probe 3. The rotating ring 13 can rotate on the outer wall of the ring rail 12. When the two groups of gears 11 are driven to rotate in opposite directions by the servo motor 8, the crown gear 14 is driven to rotate through the meshing action of the gear 11 and the crown gear 14. The rotation of the crown gear 14 drives the rotating ring 13 to rotate synchronously. The rotation of the rotating ring 13 can drive the connecting arms 15 to rotate synchronously, thereby driving the cleaning brushes 16 to rotate on the outer wall of the detection probe 3 to automatically clean the detection probe 3, thus reducing the interference of undersea sediment and sundries on the device and continuously cleaning to ensure that the equipment is always in the best working state during long-term deployment.

[0026] A speed reducer 17 is arranged on the outer wall of one side of the sealed chamber 2. The end of a rotating rod 9 on one side is connected to the output shaft of the speed reducer 17 through a coupling. The input shaft of the speed reducer 17 is connected with a drive shaft 18. A flow guiding turbine 19 is connected to the outer wall of the drive shaft 18. The speed reducer 17 plays the role of reducing speed and increasing torque at the same time. The flow guiding turbine 19 adopts a NACA airfoil turbine to reduce turbulent losses. Microelectrodes are embedded on the blade surface to electrolyze hypochlorous acid to inhibit barnacle attachment. A grid guard is installed around the flow guiding turbine 19 with a spacing of 5 mm to block large seaweeds or floating objects from entering. The flow guiding turbine 19 can be driven to rotate by the undersea current. The rotation of the flow guiding turbine 19 drives the drive shaft 18 to rotate synchronously. After being decelerated by the speed reducer 17, the drive shaft 18 drives the rotating rod 9 to rotate, thereby driving the gear 11 on one side to rotate. The rotation of the gear 11 can drive the cleaning brush 16 to rotate and clean, thus realizing the cleaning work of the detection probe 3 without power output. When the undersea current velocity is relatively large, the detection probe 3 can be cleaned without the drive of the servo motor 8. When the undersea current velocity is relatively small, the servo motor 8 can be used to assist the rotation of the flow guiding turbine 19 to drive the cleaning, thus achieving the effect of energy saving, reducing the load on the mobile power supply 25 when driving the cleaning brush 16 to clean, and increasing the service life of the mobile power supply 25 on the seabed.

[0027] A wave meter 20 is arranged on the outer wall of one side of the sealed chamber 2, and a control component 21 is arranged in the middle of the sealed chamber 2. The control component 21 includes an acquisition memory 22, a communication unit 23 and a Beidou positioning module 24. A communication unit 23 is arranged on one side of the acquisition memory 22, and a Beidou positioning module 24 is arranged on one side of the communication unit 23. The control component 21 is electrically connected to the wave meter 20 and the detection probe 3. A mobile power supply 25 is arranged at the bottom of the control component 21. The wave meter 20 uses a Nortek AWAC acoustic Doppler profiler, which can synchronously measure flow velocity, wave height and direction. The acquisition memory 22 in the control component 21 can store the data detected by the detection probe 3 and the wave meter 20 so that it can be uploaded after the working cycle ends. The Beidou positioning module 24 and the communication unit 23 enable the staff at sea to establish a data connection with the device and accurately know the specific location of the device. The mobile power supply 25 uses a high-energy-density lithium battery lithium thionyl chloride battery, which can ensure that the device can perform long-term continuous detection work on the seabed.

[0028] The bottom end of the base frame 1 is connected with a counterweight block 26, and the tops of the four ends of the base frame 1 are connected with a waterproof shell 27. The insides of multiple groups of waterproof shells 27 are fixedly connected with a dual-axis motor 28. The top outer wall of the waterproof shell 27 is connected with a rotating shaft 29 through a bearing. The top output end of the dual-axis motor 28 is connected to the rotating shaft 29. The outer wall of the rotating shaft 29 is connected with a spiral blade 30. The counterweight block 26 can increase the gravity at the bottom of the base frame 1, so that the base frame 1 always maintains a stable fall at the bottom position during the launch of the device, thereby improving the stability of the device. The waterproof shell 27 plays a waterproof role to prevent the dual-axis motor 28 from getting water. The dual-axis motor 28 has The body is a dual-rotor motor, and the two shafts are driven completely independently and can run simultaneously or in time-sharing. In the process of putting the device into the sea, the device is easily tilted by the factors of ocean currents, which can easily affect the direction of the detection probe 3 when the device falls to the seabed. During the falling process, when the tilt angle of the base frame 1 is too large, one or more sets of dual-axis motors 28 can be used to drive the rotating shaft 29 to rotate, and the rotation of the rotating shaft 29 drives the spiral blades 30 to rotate. A set of spiral blades 30 generates a downward thrust or an upward lift on a single side of the base frame 1, thereby adjusting the entire device so that it can ensure that the detection probe 3 sits on the bottom in an upward direction, thereby improving the stability of the device.

[0029] At the bottom of the four ends of the chassis 1, there are movable grooves 31. The top inner wall of the movable groove 31 is connected with a screw rod 32 through a bearing. The bottom output end of the double-shaft motor 28 is connected with the screw rod 32. The outer wall of the bottom of the screw rod 32 is threadedly connected with a threaded cylinder 33. The bottom end of the threaded cylinder 33 is connected with a moving block 34. On both sides of the middle inner wall of the movable groove 31, there are strip-shaped grooves 35. On both outer walls of the moving block 34, there are sliding blocks 36. The sliding blocks 36 are embedded in the strip-shaped grooves 35. The movable groove 31 plays a limiting role. Through the bottom output end of the double-shaft motor 28, the screw rod 32 can be driven to rotate. The rotation of the screw rod 32 drives the threaded cylinder 33 to move up and down. The up and down movement of the threaded cylinder 33 drives the moving block 34 to move up and down synchronously. By embedding the sliding blocks 36 in the strip-shaped grooves 35, it plays a limiting role to prevent the threaded cylinder 33 from rotating synchronously with the screw rod 32. The helix angle between the screw rod 32 and the threaded cylinder 33 is less than the friction angle, having self-locking property.

[0030] The bottom end of the moving block 34 is connected with a lead screw 37 through a bearing. The bottom inner wall of the movable groove 31 is fixedly connected with an internal thread block 38. The lead screw 37 meshes with the internal thread block 38. The bottom end of the lead screw 37 is connected with a spike part 39. When the moving block 34 moves, it can drive the lead screw 37 to move synchronously, so that the spike part 39 can be pushed into the sediment at the bottom of the sea. At the same time, the lead screw 37 meshes with the internal thread block 38, so that the lead screw 37 rotates while descending, and thus rotates into the seabed ground, improving the stability of the device. The helix angle between the lead screw 37 and the internal thread block 38 is greater than the friction angle and does not have self-locking property. At the same time, during the drilling process of the spike part 39, the double-shaft motor 28 can be driven to drive the spiral blade 30 to rotate, so as to increase the downward pressure of the device and avoid difficult drilling.

[0031] On one side of the inner wall of the sealed chamber 2, there is a horizontal sensor 40. At the bottom end of the horizontal sensor 40, there is a controller 41. On one side outer wall of the chassis 1, there is a lifting ring 42. Through the horizontal sensor 40, the horizontal angle of the device can be detected, so as to adjust the level through the spiral blade 30. The controller 41 plays a control role. Through the lifting ring 42, it can be connected with a rope so that after the device system completes a monitoring cycle, the system can be taken out of the water and the data can be exported.

[0032] The implementation principle of the embodiment of the present application is as follows: first, the device is connected to the rope through the lifting ring 42, and the device is thrown into the sea surface required for detection. The device gradually falls to the seabed, and the gravity at the bottom of the base frame 1 can be increased by the counterweight block 26, so that the base frame 1 always maintains a stable fall at the bottom position during the launch of the device, thereby improving the stability of the device. The waterproof shell 27 plays a waterproof role to prevent the dual-axis motor 28 from entering the water. The dual-axis motor 28 is specifically a dual-rotor motor. The two shafts are completely independently driven and can operate simultaneously or in a time-sharing manner. In the process of throwing the device into the sea, the device is easily tilted by the factors of the ocean current, which can easily affect the direction of the detection probe 3 when the device falls to the seabed. During the falling process, when the tilt angle of the base frame 1 is too large, one or more groups of dual-axis motors 28 can be used to drive the rotating shaft 29 to rotate, and the rotation of the rotating shaft 29 drives the spiral blades 30 to rotate, and a group of spiral blades 30 are used to drive the base frame A single side of 1 generates a downward thrust or an upward lift, thereby adjusting the device as a whole so that it can ensure that the detection probe 3 sits on the bottom in the upward direction, thereby improving the stability of the device. The detection probe 3 is a Doppler current meter. The arc surface design of the detection probe 3 can reduce the water flow resistance and expand the sensing coverage range. The wave meter 20 uses the NortekAWAC acoustic Doppler profiler, which can synchronously measure the flow velocity, wave height and direction. The data detected by the detection probe 3 and the wave meter 20 can be stored through the acquisition memory 22 in the control component 21, so as to be uploaded after the working cycle ends. The Beidou positioning module 24 and the communication unit 23 enable the sea staff to establish a data connection with the device and accurately know the specific location of the device. The mobile power supply 25 uses a high-energy-density lithium battery lithium thionyl chloride battery, which can ensure that the device can perform long-term continuous detection work on the seabed; When there is sediment attached to the surface of the detection probe 3, the servo motor 8 can be driven to drive the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the second bevel gears 10 on both sides to move in opposite directions, thereby driving the two sets of rotating rods 9 to move synchronously in opposite directions. The rotation of the rotating rods 9 drives the gears 11 to rotate synchronously. Through the meshing action of the gears 11 and the crown gear 14, the crown gear 14 is driven to rotate. The rotation of the crown gear 14 drives the rotating ring 13 to rotate synchronously. The rotation of the rotating ring 13 can drive the connecting arm 15 to rotate synchronously, thereby driving the cleaning brush 16 to rotate on the outer wall of the detection probe 3 to automatically clean the detection probe 3. Thus, the interference of submarine sediment and sundries on the device is reduced, and continuous cleaning ensures that the equipment is always in the best working state during long-term deployment. The submarine ocean current can drive the guide vane turbine 19 to rotate. The rotation of the guide vane turbine 19 drives the drive shaft 18 to rotate synchronously. After the drive shaft 18 is decelerated by the reducer 17, it drives the rotating rod 9 to rotate, thereby driving the gear 11 on one side to rotate. The rotation of the gear 11 can drive the cleaning brush 16 to rotate and clean, so as to realize the cleaning work of the detection probe 3 without power output. When the flow rate of the submarine ocean current is large, the detection probe 3 can be cleaned without the drive of the servo motor 8. When the flow rate of the submarine ocean current is small, the servo motor 8 can be used to assist the rotation of the guide vane turbine 19 to drive the cleaning, thus achieving the effect of energy saving, reducing the load on the mobile power supply 25 when driving the cleaning brush 16 to clean, and increasing the service life of the mobile power supply 25 under the sea.
