Description

Technical Field

[0001] The invention relates to an automatic detection device for marine ecological environment, belonging to the technical field of marine environment observation. Background Art

[0002] Automatic detection devices for the marine ecological environment are fixed observation equipment deployed in the marine environment. They are mainly used to continuously collect hydrological and meteorological data (such as water temperature, salinity, pH value, dissolved oxygen, etc.) around the clock. These devices are usually fixed in designated sea areas and rise and fall with the waves. The underwater part is equipped with sensors for in-situ monitoring. By observing the marine environment, they can provide accurate marine meteorological information in a timely manner to help people prevent and respond to marine disasters such as typhoons, tsunamis, storm surges, etc.

[0003] After the existing marine ecological environment monitoring device is placed on the sea surface, due to the lack of adequate protection of the monitoring device, the underwater sensor is exposed to the marine environment for a long time and is easily interfered with by floating objects (such as algae, plastic garbage) or fish collisions, resulting in data distortion; at the same time, marine garbage floating on the surface of the sea, such as plastic bags, is easily accumulated around the monitoring device under the push of the waves, and even hangs on the surface of the monitoring device. This will not only affect the normal operation of the device, but may also cause physical damage to the device and shorten its service life. During the floating process of the monitoring device, due to the action of the water flow, vortices are easily formed at the tail of the device. These vortices will not only cause garbage adsorption and aggregation, affecting the balance and stability of the device, but may also cause damage to the precision components inside the device. Summary of the Invention

[0004] The present invention provides an automatic detection device for marine ecological environment to solve the problems of marine garbage accumulation, water flow interference and eddy current in the prior art.

[0010] The first floating body assembly has a first through hole and a second through hole at both ends thereof, which are connected to the first channel. Seawater enters the first channel through the first through hole and the second through hole, so that seawater convection at both ends destroys the conditions for forming a low-pressure zone, thereby reducing the probability of garbage attachment.

[0012] The first float assembly and the second float assembly are connected by a first connecting assembly and a second connecting assembly.

One end of the lifting rope is wound around the winding roller, and the other end passes through the bottom of the first float assembly and is connected to the second float assembly.

[0016] Beneficial effects of the present invention:

[0017] The present invention provides an automatic detection device for a marine ecological environment. The device has a float with one end having a blunt shape and the other end having a tapered teardrop shape, so that water can smoothly bypass the device, reducing the formation of tail vortices, thereby reducing the phenomenon of garbage gathering due to vortex adsorption. The water inlet of the detection component is designed to be trumpet-shaped, with a small opening at one end of the outer wall of the filter frame, which can effectively prevent garbage from entering the water inlet and causing blockage. The extrusion component moves up and down in the filter frame to seal and open the water inlet, and squeezes the seawater in the filter frame after detection to form a pulsed backwash water flow, further preventing the water inlet from being blocked. The float and the detection part are rotatably connected by a support column. When encountering obstacles such as garbage, the float can automatically rotate to avoid them, reducing direct collision damage and improving the durability of the equipment in complex marine environments. The sealing plate of the detection component can be flipped open during detection and sealed after detection, reducing unnecessary contact between the detection component and seawater, extending the service life and improving detection stability. A pump body and a first airbag are added in the first channel to cooperate with the air pump component to achieve active vortex control. When the water velocity decreases, the pump ejects seawater through a specific through-hole, forming a jet that replenishes the boundary layer's kinetic energy, narrowing the low-pressure zone and reducing vortex intensity. The first through-hole is angled at 35°, creating a lateral momentum component in the jetted water. This disrupts the regularity of vortex shedding, inhibits the formation of Karman vortex streets, and reduces the vibration amplitude of the float. The synergistic action of the magnetic assembly and the second airbag enables the float assembly to autonomously sink and rise. When testing surface hydrology, the magnetic assemblies engage, and the second airbag inflates to seal the through-hole. When conducting layered testing, the magnetic assembly is de-energized, the second airbag deflates, and seawater enters the float assembly. By varying the internal seawater filling volume, the buoyancy is adjusted, enabling autonomous sinking. A combination of winding rollers, lifting ropes, and synchronous belts allows precise control of the float assembly's sinking speed and depth to meet the testing requirements of different water layers. A rotating assembly is installed between the float assemblies, enabling active and precise steering of the float device. The motor drives the limit plate to rotate, driving the float assembly to rotate synchronously to achieve direction adjustment. After the float device adjusts the angle, the pump body controls the specific through-hole to spray water, which can drive the float device to move and achieve flexible movement.

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The present invention provides an automatic detection device for a marine ecological environment, which includes a float part 1 and a detection part 2, wherein the float part 1 includes a first float component 11 and a second float component 12. The first float component 11 and the second float component 12 have the same structure and an intermediate structure inside to form a cavity. The first float component 11 and the second float component 12 are relatively fixed. One end of the float part 1 is round and blunt, and the other end is in a tapered teardrop shape, so that the water flow bypasses smoothly and reduces the tail vortex. The first float component 11 is provided with a first channel 111 running through both ends. The first channel 111 is located near the first float component 11 and the second float component On both sides of one end of 12, the first float assembly 11 is respectively provided with a first through hole 1111 and a second through hole 1112 connected to the first channel 111, and the detection part 2 includes a functional component 21 and a detection component 22. The functional component 21 and the detection component 22 are respectively located inside the first float assembly 11 and the second float assembly 12. The functional component 21 extends outward from the top of the first float assembly 11 and is rotatably connected to the first float assembly 11. A fixed support column 211 is provided at the bottom of the functional component 21. The support column 211 is rotatably connected to the first float assembly 11, and the detection component 22 extends through the second float assembly 12. The bottom extends downward, the detection component 22 includes a detection module 221 and a filter frame 222. The filter frame 222 is located at the bottom of the second float assembly 12 and is fixedly connected to the second float assembly 12. A sealing plate 223 is provided in the filter frame 222. A second cavity is formed between the sealing plate 223 and the top of the detection module 221. The detection module 221 is located inside the second cavity. A plurality of circumferentially distributed water inlet holes 225 are provided on the filter frame 222. The water inlet holes 225 are located below the sealing plate 223. The water inlet holes 225 are bell-shaped, wherein the water inlet holes 225 are located at one end of the outer wall of the filter frame 222 as a small mouth, and the bottom of the sealing plate 223 is provided with a The extrusion assembly 224 matches the water inlet hole 225, and the sealing plate 223 can be flipped downward to open and seal. The extrusion assembly 224 includes a telescopic rod 2241 and an extrusion plate 2242. The telescopic rod 2241 is located at the bottom of the filter frame 222 and is fixedly connected to the filter frame 222. The extrusion plate 2242 is located at the top of the telescopic rod 2241 and is fixedly connected to the telescopic rod 2241. The extrusion plate 2242 moves upward along the inner wall of the filter frame 222 through the telescopic rod 2241. The thickness of the extrusion plate 2242 is greater than the thickness of the multiple water inlet holes 225 located on the filter frame 222, and can completely block the water inlet holes 225.

[0032] When in use, the device is placed on the sea surface, and the first float assembly 11 and the second float assembly 12 enable the device to float on the sea surface. The second float assembly 12 expects the bottom of the first float assembly 11 to be submerged in the sea water. When the detection process is required, the telescopic rod 2241 drives the extrusion plate 2242 to move downward, so that the extrusion plate 2242 no longer blocks the water inlet hole 225, and the seawater enters the filter frame 222 through the water inlet hole 225. The sealing plate 223 is flipped downward to open, and the detection module 221 contacts the seawater to collect and detect the seawater. During the process, the water inlet hole 225 can filter the garbage in the water, wherein the water inlet hole 225 is a bell mouth and the end close to the outer side of the filter frame 222 is a large mouth, which can effectively prevent garbage from entering the water inlet hole 225 and causing blockage. When the detection module 221 completes the collection of seawater, the sealing plate 223 continues to flip to seal the second cavity, reducing unnecessary contact between the detection component 22 and seawater, extending the service life and improving the detection stability. The telescopic rod 2241 starts to drive the squeezing plate 2242 to move up and down to seal the water inlet hole 225. The squeezing plate 2242 squeezes the filter frame 222 during the movement. The seawater in the filter frame 22 is squeezed, and the seawater is squeezed by the squeezing plate 2242 and then discharged to the outside through the water inlet 225. The seawater can flush the water inlet 225 in the process of discharging the filter frame 222, further avoiding the water inlet 225 from being blocked. In the process of the floating body 1 floating in the seawater, the garbage in the seawater floats on the sea level, which is easy to surround the floating body 1, hindering the operation of the equipment and being surrounded by garbage for a long time. It is easy to affect the balance of the floating body 1. The floating body 1 is rotated with the detection part 2 through the support column 211 during the floating process. When encountering objects such as garbage, the floating body 1 is connected to the detection part 2 through the support column 211. The float part 1 can automatically rotate to avoid collision, reduce direct collision damage, and improve the durability of the equipment in complex marine environments. One end of the float part 1 is round and blunt, and the other end is a tapered teardrop shape, so that the water flow can bypass smoothly, reduce the tail vortex, and make the water flow transition smoothly, avoiding the sudden separation of the water flow to form a vortex, thereby reducing the phenomenon of garbage gathering due to vortex adsorption, and attracting light garbage to attach. The first channel 111 at the bottom of the first float component 11 can connect the two ends of the first float component 11, so that seawater can flow through the middle, further reducing the strength of the low-pressure area and reducing the probability of garbage attachment.

[0033] Compared with the existing technology, the asymmetric teardrop-shaped structure formed by the first float component 11 and the second float component 12 allows the water to flow smoothly, which can reduce the intensity of the low-pressure area at the tail, reduce the probability of garbage adsorption, and significantly improve the operating stability under complex sea conditions. A through-type first channel 111 is set at the bottom of the first float component 11, and cooperates with the first through hole 1111 and the second through hole 1112 at both ends to form a two-way flow guide path, which can increase the water flow speed at the bottom of the float, effectively destroy the conditions for the formation of the low-pressure area, and reduce the probability of garbage attachment. The water inlet 225 adopts a reverse bell-mouth structure to cooperate with the reciprocating motion of the extrusion component 224. During detection, the telescopic rod 2241 drives the extrusion plate 2242 downward to open the water inlet. After the detection, the seawater in the filter frame 222 is positively squeezed during the upward process to form a pulsed backwash water flow, which can extend the blocking period of the water inlet hole. The functional component 21 is rotatably connected to the floating body 1 through the support column 211. When an obstacle is detected, the floating body can be deflected around the axis of the support column, and the diversion effect of the teardrop-shaped shell can be used to make the obstacle slide smoothly along the surface of the floating body.

[0034] Example 2

[0035] In the above embodiment, the first channel 111 at the bottom of the first float assembly 11 is connected to the two ends of the bottom, so that seawater can flow through the middle, further reducing the intensity of the low-pressure area and reducing the probability of garbage attachment. However, when the water flow speed changes, the device is stationary or encounters ocean current disturbances, the tail may still form a strong low-pressure vortex area due to boundary layer separation, attracting garbage to gather. Therefore, the embodiment of the present application optimizes the float part 1 to a certain extent based on the above embodiment.

[0036] In this embodiment, a pump body and a first airbag 1113 matching the first channel 111 are provided in the first channel 111, and an air pump assembly 13 is provided in the first float assembly 11. The air pump assembly 13 draws and releases air from the outside and is connected to the first airbag 1113 to achieve collision and contraction of the first airbag 1113. The first airbag 1113 is a plurality of airbags located on one side of the inner wall of the first channel 111 and fixedly connected to the first channel 111. The first through hole 1111 is located on the first float assembly 11 and is inclined at 35°.

[0037] When in use, water flows through the teardrop-shaped tail, and the kinetic energy is attenuated due to the viscosity, and the boundary layer separates to form a low-pressure vortex zone. A vortex is generated at the tail of the first float assembly 11. When the water flow speed decreases and the kinetic energy is insufficient, seawater is pumped out through the second through hole 1112 by the pump body and flows out from the first through hole 1111, so that the outflowing water replenishes the boundary layer kinetic energy, delays flow separation, and reduces the scope of the low-pressure zone, thereby solving the problem of vortex recurrence in passive design under non-uniform water flow or low-speed scenarios. The first through hole 1111 is tilted at 35° to destroy the periodic shedding structure of the vortex, reduce the vortex intensity, and cause the jet water flow to generate a lateral momentum component, disrupting The regularity of vortex shedding suppresses the formation of Karman vortex street, which can significantly reduce the vibration amplitude of the float and extend the service life of the equipment. The expansion size of the first airbag 1113 is controlled according to the air pump component 13 based on the vortex intensity. The Bernoulli principle is used to expand the first airbag 1113 to change the diameter of the first channel 111, thereby changing the speed of the water flowing out of the first through hole 1111, maintaining the vortex suppression effect with low energy consumption, and spraying water through the first through hole 1111. A dynamic disturbance area is formed at the tail of the float, so that the water flow close to the float always maintains a certain speed, and the shear force of the water flow is used to prevent the deposition of garbage particles, achieving a "zero attachment" effect.

[0038] Compared with the prior art, the new system achieves active vortex control by adding a pump body and a first airbag 1113 within the first channel 111, in conjunction with the air pump assembly 13. When the water velocity decreases, the pump body draws seawater through the second through-hole 1112 and ejects it from the 35°-inclined first through-hole 1111, forming a jet that replenishes the boundary layer's kinetic energy. This reduces the low-pressure area, reduces vortex intensity, significantly inhibits the formation of Karman vortex streets, and reduces the vibration amplitude of the float. The 35° inclination of the first through-hole 1111 creates a lateral momentum component in the jet, disrupting the regularity of vortex shedding and reducing the frequency of vortex shedding. This creates a dynamic disturbance zone at the tail of the float, utilizing the shear force of the water flow to prevent the deposition of garbage particles, achieving a "zero adhesion" effect. The first airbag 1113 expands and contracts through the air pump assembly 13, utilizing the Bernoulli principle to change the diameter of the first channel 111, thereby regulating the velocity of the water ejected from the first through-hole 1111. When the vortex intensity is large, the airbag expands to reduce the channel diameter and increase the jet velocity; when the vortex is weak, the airbag contracts to expand the channel diameter and reduce energy consumption, which can reduce the energy consumption of vortex suppression while maintaining the vortex intensity suppression rate.

[0039] Example 3

[0040] In the above embodiment, the garbage around the float part 1 is cleaned by cooperating with the pump body and the first through hole 1111, but the traditional float part 1 is mostly fixedly connected and cannot be quickly separated or combined according to the detection requirements, especially when layered detection is required. Therefore, the embodiment of the present application optimizes the float part 1 based on the above embodiment.

[0041] In this embodiment, the first float assembly 11 and the second float assembly 12 are connected by a first connecting assembly 14 and a second connecting assembly 15. The first connecting assembly 14 includes a magnetic assembly 141. There are multiple magnetic assemblies 141. The multiple magnetic assemblies 141 are linearly distributed on the first float assembly 11 and the second float assembly 12. The magnetic assembly 141 includes a first magnet 113 and a second magnet 121 that cooperates with the first magnet 113. The first magnet 113 is located between the end of the first float assembly 11 close to the second float assembly 12 and the first float assembly 11. The second magnet 121 is fixedly connected, and is located at one end of the second float assembly 12 close to the first float assembly 11 and is fixedly connected to the second float assembly 12, wherein the first magnet 113 is an electromagnet, and the second float assembly 12 is provided with a fifth through hole 122 and a second air bag 123 matching the fifth through hole 122. The fifth through hole 122 is located at one end of the bottom of the second float assembly 12 and passes through the interior of the second float assembly 12. The second air bag 123 is located inside the second float assembly 12 and is connected to the air pump assembly 13, and the expansion of the second air bag 123 is controlled by the air pump assembly 13;

[0042] The second connecting component 15 is located on the first floating component 11 and is symmetrically arranged at both ends. The second connecting component 15 includes a winding roller 151 and a lifting rope 152. The winding roller 151 is located inside the first floating component 11. One end of the lifting rope 152 is wound around the winding roller 151, and the other end of the lifting rope 152 passes through the bottom of the first floating component 11 and is connected to the second floating component 12. A synchronous belt 153 is provided between the winding rollers 151 at both ends, and one end of the winding roller 151 is driven to rotate by a motor.

[0043] A second channel 112 corresponding to the second float assembly 12 is provided at the bottom of the first float assembly 11. The second channel 112 is arranged in a ring shape and fixedly connected between the bottom of the first float assembly 11 and the first float assembly 11. A matching pump body is provided in the second channel 112. A third through hole 1121 is provided at one end of the second channel 112. The third through hole 1121 is a water inlet. The second channel 112 is also provided with a plurality of fourth through holes 1122 matching the third through hole 1121. The plurality of fourth through holes 1122 are located on the second channel 112 and are linearly distributed in a circle.

[0044] When the surface hydrological detection is carried out, the first magnet 113 is energized, the magnetic poles of the first magnet 113 and the magnetic poles of the second magnet 121 are attracted to each other, and the air in the second airbag 123 is inflated to block the fifth through hole 122 so that the second float assembly 12 and the first float assembly 11 are fitted together, so that the detection assembly 22 can perform surface hydrological detection. When stratified hydrological detection is required, the air in the second airbag 123 is deflated through the air pump assembly 13, and seawater enters the second float assembly 12 through the fifth through hole 122. At the same time, the first magnet 1 13 When the power is turned off, the second magnet 121 is no longer attracted. As seawater enters the second float assembly 12, the weight of the second float assembly 12 increases. By changing the amount of seawater filled in the second float assembly 12, the buoyancy is adjusted to achieve the second float assembly 12 sinking autonomously. The motor drives the winding roller 151 to rotate, and the lifting rope 152 is lowered. The lifting rope 152 is used to control the speed and depth of the second float assembly 12 to accurately locate the target water depth. When the second float assembly 12 reaches the specified depth, the telescopic rod 2241 starts working, and the detection module 221 performs detection. When the detection is completed, the air pump assembly 13 is used to inflate the second airbag 123. The second airbag 123 squeezes the seawater inside the second float assembly 12 and discharges it from the fifth through hole 122, so that the weight of the second float assembly 12 is reduced. Under the buoyancy of the seawater and the rotation of the winding roller 151 driven by the motor, the second float assembly 12 is lifted through the lifting rope 152. The first float assembly 11 is on the sea surface for a long time, and the bottom is prone to accumulation of algae, debris, etc. due to the sluggish water flow, leading to To prevent the connection surface from being polluted, when the second float assembly 12 begins to approach the first float assembly 11, the pump body starts to work and starts to inject seawater into the second channel 112 through the third through hole 1121, and discharges it through the fourth through hole 1122, and expels the garbage at the bottom of the first float assembly 11 through the fourth through hole 1122, and directionally flushes the garbage at the bottom of the first float assembly 11, so that the first magnet 113 starts to be energized to adsorb the second magnet 121, thereby ensuring the relative fixation between the first float assembly 11 and the second float assembly 12.

[0045] Compared to existing technologies, the synergistic effect of the magnetic attraction assembly 141 and the second airbag 123 enables the float assembly to autonomously sink and float. When testing surface hydrology, the first magnet 113 is energized to attract the second magnet 121, and the second airbag 123 is inflated to block the fifth through-hole 122, allowing the second float assembly 12 to adhere to the first float assembly 11. When performing layered testing, the first magnet 113 is de-energized and the second airbag 123 is deflated, allowing seawater to enter the second float assembly 12 through the fifth through-hole 122. By adjusting the internal seawater filling volume, the buoyancy is adjusted, achieving autonomous sinking. The combination of the winding roller 151, the lifting rope 152, and the synchronous belt 153 allows precise control of the sinking speed and depth of the second float assembly 12. The motor drives the winding roller 151 at one end to rotate, and the winding rollers 151 at both ends rotate synchronously through the synchronous belt 153. The lifting rope 152 is lowered to control the descent speed and depth of the second floating assembly 12. An annular second channel 112 is set at the bottom of the first floating assembly 11. Seawater is injected from the third through hole 1121 through the pump body and discharged from multiple circumferentially linearly distributed fourth through holes 1122 to form a directional flushing water flow to expel the garbage at the bottom of the first floating assembly 11. The rapid fitting of the floating assembly is achieved through the coordinated action of the electromagnet and the second airbag 123. When testing surface hydrology, the first magnet 113 is energized to attract the second magnet 121, and the second airbag 123 is inflated to block the fifth through-hole 122, allowing the second float assembly 12 to fit tightly against the first float assembly 11. After the test is complete, the second airbag 123 is inflated to squeeze out the internal seawater, reducing the weight and enabling rapid recovery in conjunction with the lifting rope 152. By adjusting the inflation and deflation of the second airbag 123 and the amount of seawater inside the second float assembly 12, adaptive layer detection is achieved. When layer detection is required, the second airbag 123 is deflated, allowing seawater to enter the second float assembly 12, increasing its weight and causing it to sink. After the test is complete, the second airbag 123 is inflated to squeeze out the seawater, reducing its weight and causing it to float.

[0046] Example 4

[0047] In the above embodiment, the autonomous sinking and floating of the float assembly is achieved through the coordinated action of the magnetic assembly 141 and the second airbag 123 . However, the embodiment of the present application optimizes the float part 1 to a certain extent based on the above embodiment.

[0048] In this embodiment, a rotating assembly 16 is provided between the first floating assembly 11 and the second floating assembly 12, and a rotating column 124 corresponding to the support column 211 is provided at the bottom of the second floating assembly 12. The rotating column 124 passes through the support column 211 and is coaxial with the support column 211 and is rotatably connected between the support columns 211. A first cavity that is mutually connected is provided in the support columns 211 and 124. The rotating assembly 16 is located in the first cavity. The rotating assembly 16 includes a limiting disk 161 and a limiting structure 162. The limiting structure 162 is located on both sides of the limiting disk 161. The limiting disk 161 is driven by a motor. The limiting disk 161 is elliptical, and a notch is provided at one end. The limiting structure 162 includes a first limiting plate 1621 and a second limiting plate 1622. The first limiting plate 1621 and the second limiting plate 1622 are both between the rotating column 124 Coaxially, the second limit plate 1622 is slidably connected to the bottom of the rotating column 124, and the second limit plate 1622 is provided with a limit slide groove 1623 corresponding to the limit plate 161 on the side close to the limit plate 161. The limit slide groove 1623 extends from the side of the second limit plate 1622 to the midpoint of the second limit plate 1622. The first limit plate 1621 is located on the side of the second limit plate 1622 close to the rotating column 124. The first limit plate 1621 and the second limit plate 1622 are connected by a leaf spring 1624. The second limit plate 1622 is provided with a groove 1625 corresponding to the first limit plate 1621. A plurality of limit blocks 163 are provided on the inner wall of the rotating column 12. The plurality of limit blocks 163 are distributed circumferentially on the inner wall of the rotating column 124, and the gaps between the plurality of limit blocks 163 match the limit structure 162.

[0049] When in use, when there is a large amount of garbage around the floating body 1 or the device needs to be moved to a specified position, the motor drives the limit plate 161 to rotate. When the floating body 1 needs to rotate left, the motor drives the limit plate 161 to rotate left, and one end of the limit plate 161 is stuck in the limit slide groove 1623 in the second limit plate 1622 on the corresponding side. The limit plate 161 is elliptical and squeezes the second limit plate 1622. The second limit plate 1622 drives the first limit plate 1621 to move toward the inner wall of the rotating column 124. The first limit plate 1621 is stuck in the gap between the two adjacent limit blocks 163, and the limit blocks 163 limit the two sides of the first limit plate 1621. As the limit plate 161 continues to be squeezed, the leaf spring 1624 begins to elastically deform, and one side of the first limit plate 1621 is stuck in the groove 1625, limiting The disk 161 drives the second limit plate 1622 to rotate synchronously in the limit slide groove 1623, and the second limit plate 1622 drives the rotating column 124 to rotate synchronously through the first limit plate 1621, thereby realizing the synchronous adjustment of the direction of the first float assembly 11. When the first float assembly 11 needs to be rotated and adjusted to the right, the limit disk 161 is driven by the motor to rotate in the opposite direction and engage in the limit slide groove 1623 in the second limit plate 1622 on the other side, thereby realizing the upgrade from "passive following the flow" to "active and precise steering", and enhancing the autonomous adaptability of the device in complex environments. After the float part 1 adjusts the angle, the pump body starts to control the first through hole 1111 to spray water, which can drive the float part 1 to move. During the rotation of the float part 1, the first float assembly 11 can collide with the surrounding garbage and clear it away.

[0050] Compared to the prior art, active and precise steering of the floating device is achieved by providing a rotating assembly 16 between the first floating assembly 11 and the second floating assembly 12. The rotating assembly 16 is located in the first cavity within the support column 211 and the rotating column 124, and is driven by a motor to rotate the limit plate 161. When the float part 1 needs to rotate to the left, the motor drives the limit plate 161 to rotate to the left, and one end of the limit plate 161 is stuck in the limit slide groove 1623 in the second limit plate 1622 on the corresponding side, squeezing the second limit plate 1622, so that it drives the first limit plate 1621 to move toward the inner wall of the rotating column 124, and the first limit plate 1621 is stuck in the gap between the two adjacent limit blocks 163. As the limit plate 161 continues to be squeezed, the leaf spring 1624 elastically deforms, and one side of the first limit plate 1621 is stuck in the groove 1625. The limit plate 161 drives the second limit plate 1622 to rotate synchronously in the limit slide groove 1623, and then drives the rotating column 124 to rotate synchronously through the first limit plate 1621, thereby realizing the synchronous adjustment of the direction of the first float assembly 11. When it is necessary to rotate and adjust to the right, the motor drives the limit plate 161 to rotate in the opposite direction and engage the limit slide 1623 in the second limit plate 1622 on the other side, so that the floating device can actively adapt to the complex water environment and accurately reach the target position, which greatly improves the autonomous adaptability of the equipment. The limit structure 162 is located on both sides of the limit plate 161, including a first limit plate 1621 and a second limit plate 1622. The first limit plate 1621 is close to the side of the limit plate 161 and is provided with a limit slide 1623 corresponding to the limit plate 161. A plurality of limit blocks 163 distributed in a circular pattern are provided on the inner wall of the rotating column 12, and the gaps between the plurality of limit blocks 163 match the limit structure 162. During rotation, the first limiting plate 1621 snaps into the gap between two adjacent limiting blocks 163. Limiting blocks 163 limit both sides of the first limiting plate 1621, ensuring stability during rotation and effectively preventing shaking during rotation. This allows the floating device to accurately adjust its direction, improving the reliability and stability of the device. The first limiting plate 1621 and the second limiting plate 1622 are connected by a leaf spring 1624. As the limiting plate 161 squeezes the second limiting plate 1622 to drive the first limiting plate 1621, the leaf spring 1624 begins to elastically deform, acting as a buffer and reducing the impact force on the device during rotation. Once rotation is complete, the elastic restoring force of the leaf spring 1624 resets the limiting structure 162, preparing for the next rotation. Once the floating body 1 has adjusted its angle, the pump controls the first through-hole 1111 to spray water, driving the floating body 1 to move. Since the rotating assembly 16 realizes active steering of the floating device, the thrust generated by the water spraying from the pump body can more effectively push the floating device to move in the target direction, thereby realizing flexible displacement.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
