Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, specifically a three-dimensional water quality testing device based on an unmanned vessel. Background Technology

[0002] With increasing industrial pollution, changes in the quality and quantity of water sources have led to disharmony in nature. Water quality testing is crucial for the protection of aquatic ecosystems, the control of water pollution, and the maintenance of a healthy water environment. Water is a vital and active element in both geographical and social environments. Living organisms need water to grow and develop; transportation, landscaping, industrial production, and many other processes all utilize water. Water is constantly in motion, in the soil, in living organisms, and in processing plants and manufacturing enterprises. Water brings vitality and life to the world. Pollutants are carried away, diluted, and decomposed by flowing water, and are ultimately purified by nature, allowing nature to maintain balance. Water quality testing is the entire process of monitoring and measuring the types of pollutants in water, the concentration values ​​of various pollutants, and their changing trends, and evaluating the condition of water bodies.

[0003] Water quality testing requires multiple specialized sensors to work simultaneously for three-dimensional detection of water at different depths. To improve the convenience of testing, unmanned surface vessels combined with unwinding devices are now commonly used to test regional water quality. However, the following problems arise during this process: 1. When the sensor is sinking for detection, it will be affected by the water quality of the upper layer, with some impurities adhering to it, which will affect the accuracy of the detection of the lower layer of water quality. On the other hand, during the sinking process, the sensor may collide with rocks or aquatic organisms, which may damage the sensor. Furthermore, if the impurities adhering to the sensor probe are not cleaned for a long time, they will dry on the probe and affect subsequent use. 2. Since three-dimensional water quality testing requires the detection of multiple pollutant types and concentrations, multiple detection sensors are also required. How to simultaneously unwind multiple sensors to the same water layer for detection is also a problem that needs to be solved.

[0004] Based on this, a three-dimensional water quality detection device based on an unmanned vessel is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional water quality detection device based on an unmanned vessel to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A three-dimensional water quality detection device based on an unmanned vessel includes a mounting base, on which a unwinding motor is fixedly mounted. A winding rope is wound on the output shaft of the unwinding motor, and the end of the winding rope is fixedly connected to a detection chamber. A bidirectional reciprocating lead screw is connected to the detection chamber via bearings. The bidirectional reciprocating lead screw is threaded with two symmetrical ball sleeves. The two ball sleeves are rotatably connected to multiple sets of X-shaped cross linkages via multiple sets of connecting blocks. The ends of the X-shaped cross linkages are rotatably connected to limit sliders. The two limit sliders are slidably connected to limit frame seats. A detection sensor is fixedly installed inside the limit frame seats. A protective cover is fixedly connected to the limit frame seats. An automatic switching device is mounted on a bidirectional reciprocating lead screw; An automatic cleaning device is installed inside the detection compartment. A drive unit is installed inside the detection chamber.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative: a telescopic tube is fixedly installed at one end of the detection sensor, and the other end of the telescopic tube is fixedly connected to the inner wall of the detection chamber.

[0008] In one alternative: the protective cover is slidably connected to the detection chamber, the surface of the detection chamber is provided with a sealing sleeve, and the interior of the detection chamber is provided with an elastic air cushion.

[0009] In one alternative embodiment: the automatic cleaning device includes a water tank, which is fixedly installed inside the detection chamber. A water inlet pipe is fixedly connected to the top of the water tank and is fitted with a pipe cap. A water pressure plate is slidably connected inside the water tank and is slidably connected to the water inlet pipe. Several connecting pipes are fixedly connected to the bottom of the water tank. A nozzle is rotatably connected to the connecting pipe via a rotating cylinder. A driven gear is slidably connected to the nozzle via a spline. A shim is rotatably provided on the lower surface of the driven gear. A spring is provided between the connecting pipe and the shim.

[0010] In one alternative: the automatic switching device includes an electric push rod, which is fixedly installed inside the detection chamber. The output end of the electric push rod is fixedly connected to a connecting seat, and the connecting seat is fixedly connected to a rotating sleeve. The rotating sleeve is rotatably connected to an upper gear and a lower gear. The bottom end of the upper gear is provided with a drainage and cleaning device, and the lower gear is slidably connected to a key shaft.

[0011] In one alternative: the key shaft is connected to the detection chamber via a bearing, and the bottom end of the key shaft is fixedly connected to the top end of the bidirectional reciprocating lead screw.

[0012] In one alternative embodiment: the drainage cleaning device includes an inner rod, the top end of which is fixedly connected to the bottom end of an upper gear, the bottom end of which is fixedly connected to a valve seat, a rotating gear disk fixedly connected to the inner rod, a rotating ring connected to the inner rod via a bearing, and a plurality of folded valve stems fixedly connected to the rotating ring.

[0013] In one alternative: the inner rod passes through the bidirectional reciprocating screw and the key shaft, the folded valve stem has a water inlet, the folded valve stem is slidably connected to the connecting pipe, and the valve seat is slidably connected to the inner wall of the bottom drain outlet of the detection chamber.

[0014] In one alternative: the driving device includes a control motor, which is fixedly installed inside the detection chamber. A double-layer semi-tooth seat is fixedly connected to the output end of the control motor, and the lower surface of the double-layer semi-tooth seat is rotatably connected to the inner wall of the detection chamber via a rotating shaft.

[0015] In one alternative: an adjusting screw is threadedly connected to one side of the mounting base, one end of the adjusting screw is fixedly connected to a handle, and the other end of the adjusting screw is rotatably connected to a clamping plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, by setting up a detection chamber and a protective cover, keeps multiple detection sensors in a closed and protected state during the immersion of the detection chamber. This not only prevents the sensors from being exposed to water pollution before detection, but also prevents damage to the sensors from collisions with foreign objects such as fish, shrimp, and rocks, significantly extending the service life of the sensors. At the same time, the elastic air cushion set in the detection chamber can automatically compress and release pressure when the water pressure inside the chamber is too high, preventing damage to internal components due to excessive water pressure and ensuring the overall stability of the device.

[0017] This invention utilizes a circular array of multiple connecting blocks and X-shaped cross linkages distributed on a bidirectional reciprocating lead screw, along with multiple sets of limiting sliders, limiting frames, and detection sensors. This enables simultaneous water quality detection by multiple sensors, improving detection efficiency and data comprehensiveness. Furthermore, by controlling the sinking depth of the detection chamber using an unwinding motor, it can adapt to the three-dimensional detection needs of different water areas, expanding the detection range.

[0018] The automatic cleaning device and drainage cleaning device equipped in this invention work together. After the test is completed, the automatic switching device can drive the folded valve stem to move down so that the water inlet is aligned with the connecting pipe. The water pressure plate in the water tank squeezes the cleaning water and sprays it out through the nozzle. At the same time, the rotating toothed disc drives the nozzle to rotate, realizing automatic water mist cleaning of multiple sensor probes and ensuring the accuracy of subsequent tests. Moreover, the valve seat can move down to automatically discharge the residual test water in the test chamber without manual intervention, improving the convenience of operation.

[0019] In the automatic switching device of the present invention, when the electric push rod drives the upper gear and the lower gear to move, the control motor can drive the double-layer half-tooth seat (half toothed, half missing toothed) to rotate until the missing toothed surface faces the gear, so as to avoid the gear from colliding with the double-layer half-tooth seat when it moves; at the same time, the spring between the driven gear and the connecting pipe can make the driven gear move downward when the rotating gear disk collides with the driven gear, and the meshing is achieved after the teeth are misaligned, which further ensures the stability and reliability of the device operation.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-16 As shown, a three-dimensional water quality detection device based on an unmanned vessel includes a mounting base 1, a unwinding motor 2 fixedly mounted on the mounting base 1, a winding rope 3 wound on the output shaft of the unwinding motor 2, and a detection chamber 4 fixedly connected to the end of the winding rope 3. The bidirectional reciprocating screw 5 is connected to the detection chamber 4 via bearings. The bidirectional reciprocating screw 5 is threaded to two symmetrical ball sleeves 6. The two ball sleeves 6 are rotatably connected to multiple sets of X-shaped cross linkages 8 via multiple sets of connecting blocks 7. The ends of the X-shaped cross linkages 8 are rotatably connected to limit sliders 9. The two limit sliders 9 are slidably connected to limit frame seats 10. A detection sensor 11 is fixedly installed inside the limit frame seats 10. A protective cover 12 is fixedly connected to the limit frame seats 10. Automatic switching device 13 is installed on bidirectional reciprocating lead screw 5; Automatic cleaning device 14 is installed inside the detection compartment 4; The drive unit 15 is located inside the detection chamber 4.

[0025] Multiple connecting blocks 7 and X-link groups 8 are provided (e.g.) Figure 3As shown), the circular array is distributed on the ball bearing sleeve 6, and the corresponding limiting slider 9, limiting frame seat 10, detection sensor 11, and protective cover 12 are all set in corresponding quantities, thereby realizing the effect of multiple sets of detection sensors 11 simultaneously detecting water quality. During the overall descent of the detection tank 4, multiple detection sensors 11 are in a closed protective state. On the one hand, the closed internal environment can prevent the detection sensors 11 from encountering water pollution before detection. On the other hand, it can prevent the detection sensors 11 from being affected by collisions with external objects such as fish, shrimp, and stones, thereby improving the overall service life of the detection sensors 11. An elastic air cushion 21 is fixedly connected inside the detection tank 4. When the water pressure inside the detection tank 4 is too high, the elastic air cushion 21 automatically compresses and releases the pressure.

[0026] In one embodiment, a telescopic tube 16 is fixedly mounted on one end of the detection sensor 11, and the other end of the telescopic tube 16 is fixedly connected to the inner wall of the detection chamber 4. The telescopic tube 16 is used to limit the detection sensor 11 and prevent the detection sensor 11 from sliding out.

[0027] In one embodiment, the protective cover 12 is slidably connected to the detection chamber 4, the surface of the detection chamber 4 is provided with a sealing sleeve, and the inside of the detection chamber 4 is provided with an elastic air cushion 21.

[0028] The bottom chamber 4 is fixedly connected to an elastic air cushion 21. When the water pressure inside the bottom chamber 4 is too high, the elastic air cushion 21 will automatically compress and release the pressure.

[0029] In one embodiment, the automatic cleaning device 14 includes a water tank 141, which is fixedly installed inside the detection chamber 4. A water inlet pipe 142 is fixedly connected to the top of the water tank 141, and the water inlet pipe 142 is provided with a pipe cover 143. A water pressure plate 144 is slidably connected inside the water tank 141 and is slidably connected to the water inlet pipe 142. A plurality of connecting pipes 145 are fixedly connected to the bottom of the water tank 141. A nozzle 146 is rotatably connected to the connecting pipe 145 through a rotating drum. A driven gear 147 is slidably connected to the nozzle 146 through a spline. A shim 1471 is rotatably provided on the lower surface of the driven gear 147. A spring is provided between the connecting pipe 145 and the shim 1471.

[0030] The upper gear 134 drives multiple folded valve stems 1364, a rotating gear disc 1363, and a valve seat 1362 to move downwards via the inner rod 1361. After the valve seat 1362 moves downwards, the bottom of the detection chamber 4 opens, and the detection water previously added to the detection chamber 4 is automatically discharged. At the same time, the rotating gear disc 1363 aligns with the driven gear 147. When the folded valve stems 1364 move downwards, their water inlets 1365 align with the water flow channels in the connecting pipe 145. At this time, the water flow can flow through the connecting pipe 145 to the nozzle 146. Meanwhile, the pressure plates 144 in each water chamber of the water tank 141 squeeze the cleaning water. After being pressurized, the cleaning water flows through the connecting pipe 145 and the water inlets 1364. The water mist is sprayed from the nozzle 146 onto the probe of the detection sensor 11 for cleaning, thereby automatically cleaning multiple detection sensors 11. The rotating nozzle 146 further improves the cleaning effect. When the rotating toothed disc 1363 collidees with the driven gear 147 during its downward movement, the driven gear 147 will be squeezed downward by the rotating toothed disc 1363 to make way. The spring at the bottom of the driven gear 147 is in a compressed state until the teeth on the rotating toothed disc 1363 and the driven gear 147 are misaligned and meshed, so that the driven gear 147 is driven by the rotating toothed disc 1363, thus solving the problem of tooth collision.

[0031] In one embodiment, the automatic switching device 13 includes an electric push rod 131, which is fixedly installed inside the detection chamber 4. The output end of the electric push rod 131 is fixedly connected to a connecting seat 132, and the connecting seat 132 is fixedly connected to a rotating sleeve 133. The rotating sleeve 133 is rotatably connected to an upper gear 134 and a lower gear 135. The bottom end of the upper gear 134 is provided with a drainage and cleaning device 136, and the lower gear 135 is slidably connected to a key shaft 137.

[0032] When the electric push rod 131 is activated, the electric push rod 131 drives the rotating sleeve 133 to move downward as a whole through the connecting seat 132. The upper gear 134 moves to the original position of the lower gear 135. The lower gear 135 moves downward on the key shaft 137. At this time, the upper gear 134 is flush with the double-layer half-tooth seat 152. The upper gear 134 drives multiple folded valve stems 1364, a rotating gear disk 1363, and the valve seat 1362 to move downward through the inner rod 1361.

[0033] In one embodiment, the key shaft 137 is connected to the detection chamber 4 via a bearing, and the bottom end of the key shaft 137 is fixedly connected to the top end of the bidirectional reciprocating lead screw 5.

[0034] In one embodiment, the drainage cleaning device 136 includes an inner rod 1361, the top end of which is fixedly connected to the bottom end of the upper gear 134, the bottom end of which is fixedly connected to a valve seat 1362, and the inner rod 1361 is fixedly connected to a rotating gear 1363. The inner rod 1361 is connected to a rotating ring via a bearing, and the rotating ring is fixedly connected to a plurality of folded valve stems 1364.

[0035] When the folded valve stem 1364 moves downward, its water inlet 1365 aligns with the water flow channel in the connecting pipe 145. At this time, the water flow can pass through the connecting pipe 145 to the nozzle 146. Then, the control motor 151 is started again. The control motor 151 meshes with the upper gear 134 through the double-layer half-tooth seat 152. The upper gear 134 transmits the rotational force to the rotating gear 1363 through the inner rod 1361. During rotation, the rotating gear 1363 meshes with the passive gear 147, thereby driving the nozzle 146 to rotate. Since the connecting pipe 145 is in a flowing state, the water pressure plates 144 in each water chamber inside the water tank 141 will squeeze the cleaning water. After being pressurized, the cleaning water passes through the connecting pipe 145 and the water inlet 1365 and is finally sprayed out from the nozzle 146 to the probe of the detection sensor 11 for water mist cleaning, thereby realizing the automatic cleaning of multiple detection sensors 11.

[0036] In one embodiment, the inner rod 1361 passes through the bidirectional reciprocating screw 5 and the key shaft 137, the folded valve stem 1364 has a water inlet 1365, the folded valve stem 1364 is slidably connected to the connecting pipe 145, and the valve seat 1362 is slidably connected to the inner wall of the bottom drain outlet of the detection chamber 4.

[0037] In one embodiment, the drive device 15 includes a control motor 151, which is fixedly installed inside the detection chamber 4. A double-layer semi-tooth seat 152 is fixedly connected to the output end of the control motor 151, and the lower surface of the double-layer semi-tooth seat 152 is rotatably connected to the inner wall of the detection chamber 4 through a rotating shaft.

[0038] In one embodiment, an adjusting screw 18 is threadedly connected to one side of the mounting base 1, one end of the adjusting screw 18 is fixedly connected to a handle 19, and the other end of the adjusting screw 18 is rotatably connected to a clamping plate 20.

[0039] Place the mounting base 1 on the unmanned vessel to be installed. The mounting base 1 and the clamping plate 20 are used to clamp and fix the installation area on the unmanned vessel. The position of the clamping plate 20 is adjusted by rotating the adjusting screw 18 to adjust the clamping tension.

[0040] The above embodiments disclose a three-dimensional water quality detection device based on an unmanned vessel, the specific working principle and process of which are as follows: Multiple connecting blocks 7 and X-link groups 8 are provided (e.g.) Figure 3 As shown), the circular array is distributed on the ball sleeve 6, and the corresponding limiting slider 9, limiting frame seat 10, detection sensor 11, and protective cover 12 are all set in corresponding quantities, thereby realizing the effect of multiple sets of detection sensors 11 simultaneously detecting water quality. During the overall descent of the detection tank 4, multiple detection sensors 11 are in a closed protective state. On the one hand, the closed internal environment can prevent the detection sensors 11 from encountering water pollution before detection. On the other hand, it can prevent the detection sensors 11 from being affected by collisions with external objects such as fish, shrimp, and stones, thereby improving the overall service life of the detection sensors 11. An elastic air cushion 21 is fixedly connected inside the detection tank 4. When the water pressure inside the detection tank 4 is too high, the elastic air cushion 21 will automatically compress and release the pressure. The bottom of the water tank 141 has multiple branching openings for reasonable arrangement with the multiple detection sensors 11 inside the detection chamber 4. That is, the interior of the water tank 141 has multiple individual water chambers, and the bottom of the multiple water chambers are connected by a common cavity (e.g., Figure 7 As shown), a water inlet pipe 142 is fixedly connected to the top of one of the individual water chambers in the water tank 141. When cleaning water enters this individual water chamber through the water inlet pipe 142, the water chamber synchronously transfers the cleaning water to the other water chambers through the common cavity at the bottom, thereby achieving synchronous water intake for each water chamber. A pipe cap 143 is fixedly connected to the water inlet pipe 142. The water tank 141 is replenished with cleaning water through the water inlet pipe 142. Water pressure plates 144 are slidably connected inside the water tank 141. The number of water pressure plates 144 corresponds to the number of water chambers. The individual water pressure plate 144 located inside the water inlet pipe 142 is slidably connected to the surface of the water inlet pipe 142, which extends to the water inlet pipe 142. At the bottom of the water chamber, a connecting pipe 145 is fixedly connected to the bottom of the water tank 141. A nozzle 146 is rotatably connected to the connecting pipe 145. A driven gear 147 is slidably connected to the surface of the nozzle 146 via a spline. The driven gear 147 can only slide linearly on the nozzle 146. A spring is provided between the upper surface of the connecting pipe 145 and the gasket 1471. When the connecting pipe 145 is in a flow state, the pressure plates 144 in each water chamber inside the water tank 141 will squeeze the cleaning water. After being pressurized, the cleaning water passes through the connecting pipe 145 and the water inlet 1365 and is finally sprayed out from the nozzle 146 at the probe of the detection sensor 11 to perform water mist cleaning, thereby realizing the automatic cleaning of multiple detection sensors 11.

[0041] By setting the electric push rod 131 to drive the upper gear 134 and lower gear 135 to switch positions, different effects are achieved in different states when meshing with the double-layer half-tooth seat 152. In normal state, the electric push rod 131 drives the rotating sleeve 133 to be in a high position. At this time, the double-layer half-tooth seat 152 only meshes with the lower gear 135. Then, the detection sensor 11 is controlled to detect whether to push out or return to standby. When the electric push rod 131 is started, the rotating sleeve 133 drives the upper gear 134 and lower gear 135 to move down. The upper gear 134 meshes with the double-layer half-tooth seat 152. At this time, the double-layer half-tooth seat 152 only drives the drainage cleaning device 136 to work. The double-layer half-tooth seat 152 is set to a state of half teeth and half missing teeth (e.g., Figure 15 As shown, since the number of rotations and angles of the control motor 151 when controlling the rotation of the double-layer half-tooth seat 152 can be controlled, when the electric push rod 131 works, it drives the toothless side of the double-layer half-tooth seat 152 to face the upper gear 134 and the lower gear 135, thereby avoiding the upper gear 134 or the lower gear 135 from colliding with the double-layer half-tooth seat 152 after moving up and down.

[0042] A water inlet 1365 is provided on the folded valve stem 1364. The surface of the folded valve stem 1364 is slidably connected to the inside of the connecting pipe 145. A water flow channel is provided inside the connecting pipe 145. When the folded valve stem 1364 is in a high position, its closed state blocks the water flow channel. When the folded valve stem 1364 is in a low position, the water inlet 1365 is aligned with the water flow channel, and the water flow channel is in a flowable state. The surface of the valve seat 1362 is connected to the bottom piston of the detection chamber 4. When the electric push rod 131 passes through the connecting seat... 132 drives the rotating sleeve 133 to move downwards as a whole, and the upper gear 134 moves to the original position of the lower gear 135. The lower gear 135 moves downwards on the key shaft 137. At this time, the upper gear 134 is flush with the double-layer half-tooth seat 152. The upper gear 134 drives multiple folded valve stems 1364, a rotating gear disk 1363, and valve seat 1362 to move downwards through the inner rod 1361. After the valve seat 1362 moves downwards, the bottom of the detection chamber 4 opens, and the detection water that was previously added to the detection chamber 4 is automatically discharged. At the same time... Rotating the gear 1363 aligns it with the driven gear 147. When the folded valve stem 1364 moves downward, its water inlet 1365 aligns with the water flow channel in the connecting pipe 145. At this time, water can flow through the connecting pipe 145 to the nozzle 146. Meanwhile, the pressure plates 144 in each water chamber of the water tank 141 squeeze the cleaning water. After being pressurized, the cleaning water passes through the connecting pipe 145 and the water inlet 1365 and is finally sprayed out from the nozzle 146, aiming at the probe of the detection sensor 11, to perform water mist cleaning, thereby achieving cleaning of multiple detection sensors. The automatic cleaning of 11, along with the rotating nozzle 146, further enhances the cleaning effect. When the rotating toothed disc 1363 collidees with the driven gear 147 during its downward movement, the driven gear 147 is squeezed downward by the rotating toothed disc 1363 to make way. The spring at the bottom of the driven gear 147 is in a compressed state until the teeth on the rotating toothed disc 1363 and the driven gear 147 are misaligned and meshed at the top, thus realizing the operation of the driven gear 147 being driven by the rotating toothed disc 1363, thereby solving the problem of tooth collision.

[0043] In addition, an adjusting screw 18 is threadedly connected to one side of the mounting base 1. One end of the adjusting screw 18 is fixedly connected to a handle 19, and the other end of the adjusting screw 18 is rotatably connected to a clamping plate 20. The installation area on the unmanned vessel is clamped and fixed by the distance between the mounting base 1 and the clamping plate 20. The position of the clamping plate 20 is adjusted by rotating the adjusting screw 18 to achieve the clamping tension.

[0044] In use, the water quality three-dimensional detection device based on an unmanned vessel of the present invention involves placing the mounting base 1 on the unmanned vessel to be installed. The distance between the mounting base 1 and the clamping plate 20 is used to clamp and fix the installation area on the unmanned vessel. The position of the clamping plate 20 is adjusted by rotating the adjusting screw 18 to achieve the clamping tension. After the mounting base 1 is installed, the unmanned vessel is operated to the corresponding water area. After the vessel stops, the unwinding motor 2 is started to automatically unwind the rope 3. The detection chamber 4 is submerged in the water. After the submersion area is determined, the unwinding motor 2 is stopped and put into standby mode. During the submersion, the detection chamber 4 can protect the multiple detection sensors 11 inside. On the one hand, the closed internal environment can prevent the detection sensors 11 from being contaminated by water before detection. On the other hand, it can prevent the detection sensors 11 from being affected by collisions with foreign objects such as fish, shrimp, and stones. After the detection chamber 4 is positioned, the control motor 151 is started, which drives the double-layer half-tooth seat 152 to rotate. During the rotation of the double-layer half-tooth seat 152, the rotating sleeve 133 in the initial state is at a high position. At this time, the lower gear 135 meshes with the double-layer half-tooth seat 152. The rotation of the double-layer half-tooth seat 152 only drives the lower gear 135 to rotate synchronously. The lower gear 135 drives the bidirectional reciprocating screw 5 on the key shaft 137 to rotate through the keyway opened inside. During the rotation, the bidirectional reciprocating screw 5 drives the lower gear 135 to rotate. The two corresponding sets of ball sleeves 6 move closer to each other. Because the detection sensor 11 is restricted by the telescopic tube 16 and can only move linearly, the limiting frame 10, limiting slider 9, X-link group 8, and connecting block 7 on the detection sensor 11 can only perform corresponding linear limiting, thus preventing the ball sleeves 6 from rotating on the bidirectional reciprocating screw 5. This allows the rotation of the bidirectional reciprocating screw 5 to drive the linear movement of the two sets of ball sleeves 6. During the approaching process, the two sets of ball sleeves 6 will pass through their respective... The connecting block 7 drives the X-link assembly 8 to extend accordingly. The force of the extension is transmitted to the detection sensor 11 on the limit frame seat 10 through the limit slider 9. Then, the detection sensor 11 is pushed out of the detection chamber 4 as a whole. After being pushed out, the exposed detection sensor 11 can perform real-time detection of the water environment of this layer. After the detection is completed, the drive control motor 151 continues to operate. The control motor 151 meshes with the lower gear 135 through the double-layer half-tooth seat 152. The lower gear 135 drives the bidirectional reciprocating screw 5 on the key shaft 137 to rotate through the keyway opened inside. The bidirectional reciprocating screw 5 rotates again and drives the two sets of ball sleeves 6 to gradually move away through the reverse thread on it. The X-link assembly 8 performs a corresponding retraction movement, thereby realizing the overall recovery of the detection sensor 11. During the recovery, water will be added to the detection chamber 4. At this time, the elastic air cushion 21 inside the detection chamber 4 will automatically compress and discharge according to the water pressure. At this time, the unwinding motor 2 is started to realize the winding of the rope 3. After completing the water inlet test of the test chamber 4, the electric push rod 131 is activated. The electric push rod 131 drives the rotating sleeve 133 to move downwards via the connecting seat 132. The upper gear 134 moves to the original position of the lower gear 135. The lower gear 135 moves downwards on the key shaft 137. At this time, the upper gear 134 is flush with the double-layer half-tooth seat 152. The upper gear 134 drives multiple folded valve stems 1364, a rotating gear disk 1363, and the valve seat 1362 to move downwards via the inner rod 1361. After the valve seat 1362 moves downwards, the bottom of the test chamber 4 opens, and the test water that was previously added to the test chamber 4 is automatically discharged. At the same time, the rotating gear disk 1363 aligns with the driven gear 147. When the folded valve stem 1364 moves downwards, its water inlet 1365 aligns with the water flow channel in the connecting pipe 145. At this time, the water flow can flow through the connecting pipe 145 to the nozzle 146. Then, the control motor 151 is started again. The control motor 151 meshes with the upper gear 134 through the double-layer half-tooth seat 152. The upper gear 134 transmits the rotational force to the rotating gear disk 1363 through the inner rod 1361. During the rotation, the rotating gear disk 1363 meshes with the passive gear 147, thereby driving the nozzle 146 to rotate. Since the connecting pipe 145 is in a flowing state, the water pressure plates 144 in each water chamber inside the water tank 141 will squeeze the cleaning water. After being pressurized, the cleaning water passes through the connecting pipe 145 and the water inlet 1365 and is finally sprayed out from the nozzle 146 to the probe of the detection sensor 11 for water mist cleaning, thereby realizing the automatic cleaning of multiple detection sensors 11. At the same time, the rotating nozzle 146 can further improve the cleaning effect.

Therefore, the scope of protection of this application should be determined by the scope of the claims.
