DETAILED DESCRIPTION

[0032] In use, the device is placed on the sea surface, and the first floating body assembly 11 and the second floating body assembly 12 enable the device to float on the sea surface. The second floating body assembly 12 is arranged to submerge the bottom of the first floating body assembly 11 in seawater. 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, seawater enters the filter frame 222 through the water inlet hole 225, and the sealing plate 223 is flipped downward to open, so that the detection module 221 is in contact with seawater to collect and detect seawater. In the detection process, the water inlet hole 225 can filter water garbage. The water inlet hole 225 is a horn mouth, and the end close to the outside of the filter frame 222 is large, which can effectively prevent garbage from entering the water inlet hole 225 and causing blockage. After 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 assembly 22 and seawater, prolonging the service life and improving the detection stability. The telescopic rod 2241 drives the extrusion plate 2242 to move up and down to seal the water inlet hole 225. The extrusion plate 2242 extrudes seawater in the filter frame 222 during movement, and the seawater is extruded by the extrusion plate 2242 and discharged to the outside through the water inlet hole 225. The seawater can flush the water inlet hole 225 during discharge from the filter frame 222, further preventing the water inlet hole 225 from being blocked. During the floating of the floating body part 1 in seawater, garbage in seawater floats on the sea surface, easily surrounding the floating body part 1, hindering the operation of the equipment, and easily affecting the balance of the floating body part 1. The floating body part 1 and the detection part 2 are rotationally connected by the support column 211 during floating. When encountering garbage and other objects, the floating body part 1 can automatically rotate to avoid damage, improve the durability of the equipment in complex marine environments, and the one end of the floating body part 1 is round and blunt, and the other end is a tapered water droplet shape, so that the water flow is smooth and bypasses, reduces the tail vortex, makes the water flow smooth and transitions, avoids 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 adhere. The first channel 111 at the bottom of the first floating body assembly 11 can communicate between the two ends of the first floating body assembly 11, so that seawater can flow from the middle, further reducing the strength of the low-pressure area and reducing the probability of garbage adhesion.

[0033] Compared with the prior art, the asymmetric water droplet-shaped structure formed by the first floating body assembly 11 and the second floating body assembly 12 makes the water flow smoothly, reduces the strength of the low-pressure area at the tail, reduces the probability of garbage adsorption, and significantly improves the running stability in complex sea conditions. The first floating body assembly 11 is provided with a first through channel 111 at the bottom, and the first through hole 1111 and the second through hole 1112 at both ends form a bidirectional flow guide passage, which can increase the water flow speed at the bottom of the floating body, effectively destroy the low-pressure area formation condition, and reduce the probability of garbage attachment. The water inlet hole 225 adopts a reverse horn structure and cooperates with the reciprocating movement of the extrusion assembly 224. The telescopic rod 2241 drives the extrusion plate 2242 to descend and open the water inlet when detecting, and performs positive extrusion on the seawater in the filter frame 222 during the upward process after detection, forming a pulse type backflow, which can prolong the clogging period of the water inlet hole. The support column 211 realizes the rotational connection of the functional assembly 21 and the floating body 1. When an obstacle is detected, the floating body can deflect around the support column axis, and the water droplet-shaped shell can guide the flow to make the obstacle smoothly slide along the surface of the floating body.

[0034] Embodiment 2

[0035] In the above embodiment, the first channel 111 at the bottom of the first floating body assembly 11 connects the two ends of the first floating body assembly 11, so that seawater can flow from the middle, further reducing the strength 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 disturbance, the tail may still form a strong low-pressure vortex area due to boundary layer separation, attracting garbage to gather. Therefore, the floating body 1 is optimized based on the above embodiment in this embodiment.

[0036] In this embodiment, the first channel 111 is provided with a pump body and a first air bag 1113 matched with the first channel 111. The first floating body assembly 11 is provided with an air pump assembly 13, which draws air from the outside and is connected with the first air bag 1113 to realize the collision and contraction of the first air bag 1113. The first air bag 1113 is fixedly connected between the inner wall of the first channel 111 and the first channel 111, and the first through hole 1111 is located on the first floating body assembly 11 and inclined at an angle of 35°.

[0037] In use, water flows through the water droplet-shaped tail, and due to the viscous effect, the kinetic energy is attenuated, the boundary layer separates to form a low pressure vortex area, and the first floating body assembly 11 tail generates vortex. When the water flow speed decreases to cause insufficient kinetic energy, the pump body extracts seawater through the second through hole 1112 and flows out from the first through hole 1111, so that the outflowing water flow replenishes the boundary layer kinetic energy, delays flow separation, and reduces the range of low pressure area, thereby solving the problem of vortex recurrence of the passive design in the non-uniform water flow or low speed scene. The first through hole 1111 is inclined at an angle of 35° to destroy the periodic shedding structure of the vortex, reduce the vortex intensity, make the jet water flow generate a transverse momentum component, disrupt the regularity of vortex shedding, inhibit the formation of the Karman vortex street, and can significantly reduce the floating body vibration amplitude, prolong the service life of the equipment. According to the vortex intensity, the inflation size of the first air bag 1113 is controlled by the air pump assembly 13. According to Bernoulli's principle, the diameter of the first channel 111 is changed by the inflation of the first air bag 1113, so as to change the speed of the water flow flowing out of the first through hole 1111, so as to maintain the vortex suppression effect with lower energy consumption. And through the first through hole 1111, the water flow is jetted, a dynamic disturbance area is formed at the tail of the floating body, the water flow close to the floating body always maintains a certain speed, the shear force of the water flow is used to prevent garbage particles from depositing, and a "zero attachment" effect is realized.

[0038] Compared with the prior art, by additionally arranging the pump body and the first air bag 1113 in the first channel 111, and cooperating with the air pump assembly 13, active vortex control is realized. When the water flow speed decreases, the pump body extracts seawater through the second through hole 1112 and sprays it out of the first through hole 1111 which is inclined at an angle of 35°, forming a jet flow that replenishes the boundary layer kinetic energy, which can reduce the range of low pressure area, reduce the vortex intensity, significantly inhibit the formation of the Karman vortex street, reduce the floating body vibration amplitude, and the first through hole 1111 is designed to be inclined at an angle of 35°, so that the jet water flow generates a transverse momentum component, disrupts the regularity of vortex shedding, can reduce the vortex shedding frequency, forms a dynamic disturbance area at the tail of the floating body, uses the shear force of the water flow to prevent garbage particles from depositing, and realizes a "zero attachment" effect. The first air bag 1113 is inflated and deflated by the air pump assembly 13, the diameter of the first channel 111 is changed by Bernoulli's principle, so as to adjust the flow rate of the water flow sprayed out of the first through hole 1111. When the vortex intensity is large, the air bag is inflated to reduce the channel diameter and increase the jet flow rate; when the vortex is weak, the air bag is deflated to expand the channel diameter and reduce the energy consumption, which can reduce the vortex suppression energy consumption while maintaining the vortex intensity suppression rate.

[0039] Embodiment 3

[0040] In the above embodiments, the pump body cooperates with the first through hole 1111 to clean the garbage around the floating body part 1, but the conventional floating body part 1 is usually fixedly connected and cannot be quickly separated or combined according to the detection requirements, especially when layered detection is required. Therefore, the floating body part 1 is optimized based on the above embodiments.

[0041] The first floating body assembly 11 and the second floating body assembly 12 are connected through the first connecting assembly 14 and the second connecting assembly 15. The first connecting assembly 14 comprises a plurality of magnetic attraction assemblies 141. The magnetic attraction assemblies 141 are linearly distributed on the first floating body assembly 11 and the second floating body assembly 12. The magnetic attraction assembly 141 comprises a first magnet 113 and a second magnet 121 matched with the first magnet 113. The first magnet 113 is fixedly connected between the first floating body assembly 11 and the end of the first floating body assembly 11 close to the second floating body assembly 12. The second magnet 121 is fixedly connected between the second floating body assembly 12 and the end of the second floating body assembly 12 close to the first floating body assembly 11. The first magnet 113 is an electromagnet. The second floating body assembly 12 is provided with a fifth through hole 122 and a second air bag 123 matched with the fifth through hole 122. The fifth through hole 122 penetrates the inside of the second floating body assembly 12 at the bottom end of the second floating body assembly 12. The second air bag 123 is located in the inside of the second floating body assembly 12 and is connected with the air pump assembly 13. The inflation of the second air bag 123 is controlled by the air pump assembly 13.

[0042] The second connecting assembly 15 is symmetrically arranged at both ends of the first floating body assembly 11. The second connecting assembly 15 comprises winding rollers 151 and lifting ropes 152. The winding rollers 151 are located in the inside of the first floating body assembly 11. One end of the lifting ropes 152 is wound on the winding rollers 151. The other end of the lifting ropes 152 penetrates the bottom of the first floating body assembly 11 and is connected with the second floating body assembly 12. Synchronous belts 153 are arranged between the winding rollers 151 at both ends and are connected. One end of the winding roller 151 is driven to rotate by a motor.

[0043] The first floating body assembly 11 is provided with a second channel 112 corresponding to the second floating body assembly 12. The second channel 112 is annularly arranged at the bottom of the first floating body assembly 11 and is fixedly connected with the first floating body assembly 11. A pump body matched with the second channel 112 is arranged in the second channel 112. The second channel 112 is provided with a third through hole 1121 at one end, which is a water inlet. The second channel 112 is also provided with a plurality of fourth through holes 1122 matched with the third through hole 1121. The plurality of fourth through holes 1122 are circularly and linearly distributed on the second channel 112.

[0044] When detecting the surface hydrology, the first magnet 113 is powered on, the magnetic poles of the first magnet 113 and the second magnet 121 are attracted to each other, the second air bag 123 is inflated to block the fifth through hole 122, the second float assembly 12 is attached to the first float assembly 11, and the detection assembly 22 performs surface hydrology detection. When layered hydrology detection is needed, the second air bag 123 is deflated by the air pump assembly 13, seawater enters the second float assembly 12 through the fifth through hole 122, and the first magnet 113 is powered off and no longer attracts the second magnet 121. Due to the increase in the weight of the second float assembly 12 caused by the seawater entering the second float assembly 12, the buoyancy is adjusted by changing the amount of seawater filled in the second float assembly 12 to achieve autonomous sinking of the second float assembly 12. The motor drives the winding roller 151 to rotate, and the lifting rope 152 is lowered. The speed and depth of the second float assembly 12 are controlled by the lifting rope 152 to accurately position the target water depth. When the second float assembly 12 reaches the specified depth, the extension rod 2241 starts to work, and the detection module 221 performs detection. After detection is completed, the second air bag 123 is inflated by the air pump assembly 13, the seawater in the second float assembly 12 is squeezed out of the fifth through hole 122, and the weight of the second float assembly 12 is reduced. The second float assembly 12 is lifted by the seawater buoyancy and the motor-driven winding roller 151 through the lifting rope 152. The first float assembly 11 is always on the sea surface, and the bottom is prone to accumulate algae, debris, and other materials due to slow water flow, causing the connection surface to be contaminated. When the second float assembly 12 starts to approach the first float assembly 11, the pump body starts to work, injects seawater into the second channel 112 through the third through hole 1121, and discharges it through the fourth through hole 1122. The fourth through hole 1122 expels the garbage at the bottom of the first float assembly 11, and the first magnet 113 is powered on to attract the second magnet 121, ensuring the relative fixation between the first float assembly 11 and the second float assembly 12.

[0045] Compared with the prior art, the autonomous sinking and floating of the floating body assembly is realized through the cooperation of the magnetic attraction assembly 141 and the second air bag 123. When detecting the surface hydrology, the first magnet 113 is electrified and attracted to the second magnet 121, the second air bag 123 is inflated to block the fifth through hole 122, and the second floating body assembly 12 is attached to the first floating body assembly 11.

The motor drives one end of the winding roller 151 to rotate, the synchronous belt 153 synchronously rotates the two ends of the winding roller 151, the lifting rope 152 is unwound downward, and the sinking speed and depth of the second floating body assembly 12 are controlled. The annular second passage 112 is arranged at the bottom of the first floating body assembly 11, seawater is injected from the third through hole 1121 by the pump body, and is discharged from the plurality of circumferentially linearly distributed fourth through holes 1122, forming a directional scouring flow, expelling the garbage at the bottom of the first floating body assembly 11, and realizing the rapid attachment of the floating body assembly through the cooperation of the electromagnet and the second air bag 123.

[0049] In use, when there is a large amount of garbage around the floating body 1 or the device needs to be moved to a designated position, the limiting disc 161 is driven to rotate by the motor. When the floating body 1 needs to rotate to the left, the motor drives the limiting disc 161 to rotate to the left. One end of the limiting disc 161 is clamped into the limiting sliding groove 1623 in the corresponding side second limiting plate 1622. The limiting disc 161 is elliptical and presses the second limiting plate 1622. The second limiting plate 1622 drives the first limiting plate 1621 to move towards the inner wall of the rotating column 124. The first limiting plate 1621 is clamped into the gap between the two adjacent limiting blocks 163. The limiting blocks 163 limit the two sides of the first limiting plate 1621. With the continuous extrusion of the limiting disc 161, the leaf spring 1624 begins to elastically deform. One side of the first limiting plate 1621 is clamped into the groove 1625. The limiting disc 161 drives the second limiting plate 1622 to rotate synchronously in the limiting sliding groove 1623. The second limiting plate 1622 drives the rotating column 124 to rotate synchronously through the first limiting plate 1621, thereby realizing synchronous adjustment of the direction of the first floating body assembly 11. When the first floating body assembly 11 needs to be adjusted to rotate to the right, the limiting disc 161 is clamped into the limiting sliding groove 1623 of the other side second limiting plate 1622 by reversing the rotation of the motor. This realizes the upgrade from "passive following the current" to "active precise steering", enhancing the self-adaptability of the device in complex environments. After the floating body 1 adjusts the angle, the pump body starts to control the first through hole 1111 to spray water, which drives the floating body 1 to displace. In the process of rotating the floating body 1, the first floating body assembly 11 can collide with the surrounding garbage to clean it up.

[0050] Compared with the prior art, the active and accurate steering of the floating body device is realized by arranging the rotating assembly 16 between the first floating body assembly 11 and the second floating body assembly 12. The rotating assembly 16 is located in the first cavity in the support column 211 and the rotating column 124, and is driven to rotate by the motor driving the limiting disc 161. When the floating body part 1 needs to be steered to the left, the motor drives the limiting disc 161 to rotate to the left, one end of the limiting disc 161 is clamped into the limiting sliding groove 1623 in the corresponding second limiting plate 1622, the second limiting plate 1622 is extruded, the first limiting plate 1621 is driven to move towards the inner wall of the rotating column 124, the first limiting plate 1621 is clamped into the gap between the adjacent two limiting blocks 163, and the plate spring 1624 is elastically deformed. One side of the first limiting plate 1621 is clamped into the groove 1625, the limiting disc 161 drives the second limiting plate 1622 to rotate synchronously in the limiting sliding groove 1623, and then the first limiting plate 1621 drives the rotating column 124 to rotate synchronously, so that the direction of the first floating body assembly 11 is adjusted synchronously. When it is needed to be steered to the right, the motor drives the limiting disc 161 to rotate reversely and be clamped into the limiting sliding groove 1623 in the other second limiting plate 1622, so that the floating body device can actively adapt to the complex water environment and accurately reach the target position, and the self-adaptability of the equipment is greatly improved. The limiting structure 162 is located on both sides of the limiting disc 161, including the first limiting plate 1621 and the second limiting plate 1622. The first limiting plate 1621 is provided with a limiting sliding groove 1623 corresponding to the limiting disc 161 on the side close to the limiting disc 161. A plurality of limiting blocks 163 are circumferentially distributed on the inner wall of the rotating column 12, and the gap between the plurality of limiting blocks 163 is matched with the limiting structure 162. In the rotating process, the first limiting plate 1621 is clamped into the gap between the adjacent two limiting blocks 163, the limiting blocks 163 limit the two sides of the first limiting plate 1621, the stability of the rotating process is ensured, the shaking in the rotating process is effectively avoided, the floating body device can accurately adjust the direction, and the reliability and stability of the equipment are improved. The first limiting plate 1621 and the second limiting plate 1622 are connected by the plate spring 1624. In the process that the limiting disc 161 extrudes the second limiting plate 1622 to drive the first limiting plate 1621 to move, the plate spring 1624 starts to elastically deform, plays a buffering role, and reduces the impact force on the equipment in the rotating process. When the rotating is completed, the elastic restoring force of the plate spring 1624 can reset the limiting structure 162, so as to prepare for the next rotation. After the floating body part 1 is adjusted to the angle, the floating body part 1 can be driven to displace by spraying water through the first through hole 1111 of the pump body. Since the rotating assembly 16 realizes the active steering of the floating body device, the thrust generated by the water sprayed by the pump body can more effectively push the floating body device to move towards the target direction, and flexible displacement is realized.

In general, if a person skilled in the art is inspired thereby, without departing from the spirit of the present application, without creating a similar structure and embodiment of the technical solution, which should belong to the protection scope of the present application.
