[0034] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0035] Example 1: See Figures 1 to 6 As shown, a water body cleaning device includes a water surface garbage disposer 2 and a blue algae removal device 4 connected via a pipeline 1, and a water pump 11 is provided on the pipeline 1;

[0036] The blue algae removal device 4 includes a cleaning tube 41 and at least two groups of ultrasonic components 42 arranged on the outer wall of the cleaning tube 41. A blue algae cleaning chamber 43 is provided in the cleaning tube 41. A first water inlet 44 and a first drain port 45 are respectively provided at both ends of the blue algae cleaning chamber 43. The first water inlet 44 is connected to the water surface garbage disposer 2 via a pipeline 1.

[0037] In this embodiment, in actual use, the surface garbage disposer is placed in a body of water (such as a pond or a river), and the blue algae removal device is placed on the shore and not placed in the water. The surface garbage disposer will collect the garbage on the water surface. In the process of collecting the surface garbage, the blue algae on the water surface will also enter the surface garbage disposer. The water pump will pump the water entering the surface garbage disposer through the pipeline to the blue algae removal device. Since the surface garbage disposer is mainly for filtering the surface garbage with larger size, the water and blue algae pumped into the blue algae removal device by the water pump and water enter the blue algae removal device, pass through the blue algae removal device, and then be discharged from the first drain port. In the process of water and blue algae entering the blue algae cleaning chamber from the first water inlet and then being discharged from the first drain port, the ultrasonic component will generate ultrasonic waves, and the blue algae entering the blue algae cleaning chamber will be quickly treated by ultrasonic waves (ultrasonic algae removal mainly uses the shock wave generated by the "cavitation" effect of special frequency ultrasonic waves acting on the water body to break the cell wall of blue algae, break the air cell, destroy the active enzyme, make it inactive and die, so as to achieve the purpose of preventing algae and removing algae), and the treated blue algae are sent back into the water body from the first drain port along with the water. In this way, we can not only clean up the garbage on the water surface, but also continuously clean up the blue algae, and effectively prevent the reproduction and generation of blue algae.

[0038] See also Figures 2 to 4 As shown, the ultrasonic component 42 includes a mounting shell 421 and an ultrasonic transducer 422 disposed in the mounting shell 421. The mounting shell 421 is arranged parallel to the axis of the cleaning tube 41, and the two ends of the mounting shell 421 are respectively arranged close to the two ends of the cleaning tube 41.

[0039] The inner end of the ultrasonic transducer is against the outer wall of the cleaning tube, and the ultrasonic transducer generates and transmits ultrasonic waves to the water in the blue algae cleaning chamber to clean the blue algae in the water. The setting of the mounting shell can not only install and limit the ultrasonic transducer, but also protect the ultrasonic transducer to prevent leakage from the cavity. At the same time, the mounting shell is arranged along the axial direction of the cleaning tube, and the ultrasonic transducer is also arranged along the circumferential direction of the cleaning tube, so that in the process of the water flowing from the first water inlet to the first drain outlet, it can be fully covered by the ultrasonic wave to clean the blue algae. There are multiple transducers in the mounting shell, and the multiple transducers are arranged at intervals along the axial direction of the cleaning tube to improve the ultrasonic algae removal effect.

[0040] See also Figures 2 to 4 As shown, a cover shell 46 is further provided outside the cleaning cylinder between adjacent installation shells 421 , and the cover shell 46 and the outer wall of the cleaning cylinder 41 and the adjacent installation shells 421 form a closed enhancement chamber 47 .

[0041] In this embodiment, three groups of ultrasonic components are arranged around the outside of the cleaning barrel. Therefore, three groups of cover shells are arranged on the outside of the cleaning barrel. Each group of cover shells is arranged between adjacent mounting shells to form three closed enhancement chambers. In this way, when the ultrasonic transducer generates ultrasonic waves, the effect of the ultrasonic waves can be enhanced through the enhancement chamber, which can not only improve the algae removal efficiency and quality, but also make full use of the energy of the ultrasonic transducer, thereby reducing energy consumption.

[0042] The two ends of the cover are respectively flush with the two ends of the mounting shell, and the side of the cover is connected to the middle of the side wall of the mounting shell. In this way, the chamber is as close to the outer wall of the cleaning tube as possible, so that the dissipated ultrasonic energy is dispersed to the cleaning tube as much as possible and transmitted to the water in the blue algae cleaning chamber, ensuring the blue algae cleaning effect.

[0043] See also Figure 3 As shown, one end of the mounting shell 421 is provided with a circuit mounting hole 423 communicating with the interior of the mounting shell 421, the ultrasonic transducer 422 is connected to the power supply assembly via a circuit passing through the circuit mounting hole, and a seal is provided between the circuit and the circuit mounting hole.

[0044] The setting of the line installation hole makes it convenient for the power supply component to supply power to the ultrasonic transducer, and the seal is used to seal the connection between the line and the line installation hole to prevent external water from entering the installation shell and preventing damage to the ultrasonic transducer.

[0045] See also Figure 1 As shown, a drain pipe 48 is connected to the first drain port 45. The drain pipe is used to directly return the water discharged from the first drain port to the original water body (such as a pond or a river).

[0046] See also Figure 5 , 6 As shown, the water surface garbage disposer 2 comprises an outer barrel 21, an inner barrel 22 and an isolation net barrel 23, the outer barrel 21 has a receiving chamber 24, and the top of the outer barrel 21 has a barrel opening connected to the receiving chamber 24;

[0047] The inner cylinder 22 is placed in the accommodating cavity 24. The inner cylinder 22 is a cylindrical structure with openings at the top and bottom. The inner cylinder 22 can move up and down in the accommodating cavity 24.

[0048] The isolation net barrel 23 is a cylindrical structure with an open top, and the isolation net barrel 23 can be detachably installed in the inner barrel 22;

[0049] A second drain port 25 communicating with the accommodating chamber 24 is provided on the lower side wall of the outer barrel 21. The second drain port 25 is arranged near the bottom of the accommodating chamber 24, and the second drain port 25 is arranged directly opposite to the lower side of the inner barrel 22. The second drain port 25 is connected to the first water inlet 44 via the pipeline 1.

[0050] In this embodiment, the top of the inner cylinder is arranged above the mouth of the barrel. In actual use, the outer barrel is placed in the water, and the mouth of the barrel is lower than the water level, preferably 5cm to 10cm below the water level. The inner cylinder will move downward due to its own weight. Initially, the opening at the top of the inner cylinder is below the water surface. The inner cylinder has buoyancy and can be pushed up by water, so that the water on the water surface will be injected into the inner cylinder and the accommodating cavity. As the water level in the accommodating cavity and the inner cylinder rises, the buoyancy of the inner cylinder gradually increases. When the buoyancy of the inner cylinder is greater than the gravity borne by the inner cylinder, the inner cylinder will move upward so that the opening at the top of the inner cylinder is higher than the water surface, and no water will be injected into the inner cylinder. Since the water pump is arranged on the pipeline, the water pump will continue to work to pump water into the accommodating cavity, and the water in the accommodating cavity will be pumped away through the second drain port. When the water level in the accommodating cavity drops to a certain position, the buoyancy of the inner cylinder is less than the gravity borne by the inner cylinder. When the water level rises to the point where the buoyancy of the inner tube is greater than the gravity borne by the inner tube, the inner tube moves upward again. This process is repeated as the inner tube rises and falls continuously, and the water pump continues to pump water, sending the water and blue algae into the cleaning tube through the pipeline, while the water outside the outer barrel flows toward the center of the inner tube. The garbage, blue algae, etc. on the water surface follow the water flow into the isolation net in the inner tube. The continuous up and down movement of the inner tube will cause the water flow injected into the inner tube to be sometimes fast and sometimes slow, and the surface tension generated by the water surface of the outer barrel toward the center of the inner tube will be sometimes large and sometimes small, thereby continuously accelerating the surface garbage moving toward the center of the inner tube, speeding up the collection of surface garbage, and also speeding up the flow of blue algae toward the surface garbage disposer, while also expanding the radiation area of ​​the surface garbage disposer. The garbage and blue algae on the water surface flow into the isolation net barrel in the inner barrel, and are filtered by the isolation net barrel. The garbage on the water surface remains in the isolation net barrel, and some blue algae are also blocked by the garbage on the water surface and the isolation net barrel. The filtered water and most of the blue algae are sent to the cleaning barrel through the water pump through the pipeline. The blue algae are processed by the cleaning barrel, and water circulation can be realized. When the garbage in the isolation net barrel is full, the garbage in the isolation net barrel can be cleaned. In this way, while the garbage on the water surface is being processed, the blue algae on the water surface can also be processed, thereby improving the quality of the water body.

[0051] Wherein, a float is installed on the inner tube or a closed cavity is provided in the inner tube. If a float is provided, the buoyancy of the inner tube can be increased, so that the inner tube can rise due to the buoyancy of water, and can also fall due to its own weight due to the lack of water. With the provision of the cavity, the inner tube itself will constitute a float and have buoyancy.

[0052] See also Figure 5 , 6 As shown, a suspended plate 26 is further provided between the lower part of the inner cylinder 22 and the bottom of the accommodating chamber 24, the bottom of the suspended plate 26 is connected to the outer barrel 21 via a mounting frame 27, the outer end of the mounting frame 27 is connected to the inner wall of the accommodating chamber 24, and the mounting frame 27 has a vertical spacing from the bottom of the accommodating chamber 24;

[0053] The second drain port 25 is disposed below the mounting frame 27 , and an annular gap is provided between the suspended plate 26 and the inner wall of the accommodating chamber 24 .

[0054] A plurality of buffer support blocks 28 are arranged around the top surface of the suspended plate 26, and the buffer support blocks 28 are arranged opposite to the bottom surface of the inner tube 22. When the inner tube 22 moves downward, the outer edge of the bottom surface of the inner tube 22 abuts against the top surface of the buffer support blocks 28. The buffer support blocks are made of rubber and have elasticity, so they have buffering energy.

[0055] In this embodiment, when the inner tube descends to the bottom, it is supported by the buffer support block, so that the downward moving position of the inner tube can be limited and supported. At the same time, the suspension plate is set. When the water in the inner tube flows from top to bottom, the water flow will first hit the suspension plate and be blocked by the suspension plate. This is equivalent to shortening the drainage path and reducing the drainage space, making the drainage speed faster. Furthermore, after the inner tube moves to the bottom, its bottom edge is supported by the buffer support block. The buffer support block not only plays a supporting role, but also plays a role of elastic buffering, reducing the impact force generated during the descent of the inner tube, reducing the damage to the inner tube caused by the impact, reducing the maintenance rate, and extending the service life. At the same time, after the bottom of the inner cylinder is against the buffer support block, the height between the inner cylinder and the suspended plate is only the height of the buffer support block, so that the gap between the inner cylinder and the suspended plate is small. In this way, during the process of pumping water, the water outflowing from the bottom of the inner cylinder is faster, which can better ensure that the water in the inner cylinder can smoothly enter the accommodating chamber. At the same time, a water outlet hole 31 is provided above the inner cylinder to connect the interior of the inner cylinder with the accommodating chamber. Through the setting of the water outlet hole, the water in the inner cylinder can also be discharged from the water outlet hole (in the process of garbage collection, garbage is mainly accumulated from bottom to top, so garbage is more likely to block the bottom of the isolation net barrel, and the top is generally not blocked. In this way, water can also flow from the top of the isolation net barrel into the inner cylinder, and then flow into the accommodating chamber from the water outlet hole above the inner cylinder). In this way, the flow rate of water in the inner cylinder into the accommodating chamber can be increased, thereby ensuring that the accommodating chamber is as full as possible, thereby preventing the drainage pump from sucking air, thereby reducing the maintenance rate of the drainage pump and extending its service life.

[0056] Furthermore, since the suspended plate is subject to the impact force of the inner barrel moving downward and the impact force of the water flowing downward through the isolation net barrel, the suspended plate is easily damaged and deformed. Therefore, the suspended plate is directly connected to the inner wall of the accommodating cavity through the mounting frame, and the connection strength between the suspended plate and the outer barrel is increased through the mounting frame to extend its service life. Preferably, the mounting frame adopts a cross-shaped structure, which is simple in structure, uses less materials, and has more contact points with the suspended plate and the outer barrel, ensuring strength, and does not affect the downward flow of water from the gap between the suspended plate and the accommodating cavity.

[0057] See also Figure 6 As shown, the bottom of the isolation net barrel is arranged below the bottom surface of the inner cylinder.

[0058] When the bottom of the inner cylinder is against the buffer support block, the bottom of the isolation net barrel contacts the suspension board, so when the inner cylinder moves down, the isolation net barrel will collide with the suspension board, that is, the isolation net barrel is knocked by the suspension board, and the surface garbage in the isolation net barrel is knocked and vibrated, so that the surface garbage in the isolation net barrel can shake and will not be completely blocked in the isolation net barrel, and some blue algae stuck on it can be knocked away, so that when subsequent water enters the isolation net barrel, the blue algae can be taken away and cleaned by the blue algae removal device. At the same time, the height of the isolation net barrel can be set higher, and more surface garbage can be accommodated, thereby extending the cleaning frequency of the isolation net barrel and reducing the labor intensity of operators.

[0059] See also Figure 6 As shown, a plurality of pulleys 29 are arranged in an annular manner on the inner wall of the accommodating chamber 24, and the axis of the pulley 29 is arranged perpendicular to the axis of the inner cylinder 22. A guide groove 30 facing the pulley 29 is provided on the outer wall of the inner cylinder 22, and the outer edge surface of the pulley 29 abuts against the end surface of the guide groove 30.

[0060] The pulley and the outer barrel are rotatably connected. Through the setting of the pulley and the guide groove, it can be ensured that during the up and down movement of the inner barrel, it remains in the same position and moves up and down without rotation and shaking, thereby limiting the movement of the inner barrel.

[0061] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
