The temporary storage tank 5 is communicated with an external disinfection cabinet machine, and the disinfection cabinet machine can output disinfectant and clean water, which is prior art and will not be elaborated here. The temporary storage tank 5 can be fixed through a fixing member or fixed on the top frame of the water tank 1, and can be selected according to the specific installation environment.

[0035] Furthermore, the driving member includes a support plate 6 fixedly arranged on the side wall of the temporary storage box 5, a first driving motor 38 is fixedly arranged at the bottom of the support plate 6, an output end of the first driving motor 38 is connected to the first gear 8, a second gear 26 is arranged on the rotating housing 10, and the first gear 8 is meshed with the second gear 26 for transmission. The first driving motor 38 controls the rotation of the rotating housing 10, thereby controlling the horizontal orientation of the first high-pressure nozzle 17.

[0036] Furthermore, a booster pump 28 is provided inside the fixed housing 7, and the booster pump 28 is connected to the temporary storage box 5 through an interface 27. A fixed pipe 30 is fixedly provided at the outlet of the booster pump 28, and the fixed pipe 30 is slidably and sealedly connected to the inner wall of the inner tube 13. The fixed pipe 30 is provided to ensure that the internal water delivery process is in a sealed state throughout the process of the inner tube 13 moving up and down.

[0037] Furthermore, a hydraulic chamber 1 33 is formed between the fixed tube 30 and the inner wall of the outer tube 11 and the inner tube 13, and two hydraulic holes 32 are provided on the upper wall of the hydraulic chamber 1 33. A hydraulic chamber 2 31 is provided inside the rotating shell 10, and the hydraulic holes 32 are connected to the hydraulic chamber 2 31, and the hydraulic chamber 2 31 is connected to a hydraulic passage 29 extending to the upper wall of the rotating shell 10. The hydraulic passage 29 is connected to the external hydraulic control center to control the lifting and lowering of the inner tube 13. The rotating shell 10 reciprocates, and there will be no entanglement of the connecting pipes at the hydraulic passage 29.

[0038] Furthermore, a third gear 18 is fixedly disposed in the rotating tube 16 , and a rack 12 is fixedly disposed on the outer circumferential wall of the outer tube 11 , and the rack 12 is meshed with the third gear 18 for transmission.

[0039] Furthermore, the water tank 1 is provided with a water outlet 2 , and the water tank 1 is also provided with a water inlet 3 and a sewage outlet 4 .

[0040] Furthermore, the first drive motor 38, the disinfection cabinet, and the liquid control center are controlled by the host to achieve automated operation. This process is a conventional intelligent setting and will not be described in detail here.

[0041] In a specific use environment, according to the different sizes of the water tank 1, multiple automatic cleaning devices can be set according to needs.

[0042] Before the present invention is used, the first drive motor 38 is controlled to start and drive the rotating shell 10 to rotate, and the liquid control center controls the inner tube 13 to move up and down. Before cleaning, the equipment is tested to ensure that its rotation and lifting functions are operating normally.

[0043] Before the formal start of cleaning and disinfection, the inner tube 13 is controlled to be at the uppermost position, and the first high-pressure nozzle 17 is directed toward the upper wall of the water tank 1. The drain port 4 is opened to discharge the remaining water in the water tank 1. The disinfection cabinet is first controlled to output water flow to the temporary storage box 5, and the water flow enters the fixed tube 30 through the booster pump 28, and then enters the first high-pressure nozzle 17 through the inner tube 13, the first curved tube 14, the second curved tube 15, and the rotating tube 16, and the high-pressure water flow is sprayed out to start cleaning the water tank.

[0044] Then the inner tube 13 is controlled to move upward slowly. During the upward movement of the inner tube 13, the third gear 18 engages with the rack 12, driving the rotating tube 16 to rotate, thereby driving the first high-pressure nozzle 17 to rotate, from toward the top of the water tank 1 to toward the side wall of the water tank 1 until vertically toward the bottom wall of the water tank 1, and then reset to face the upper wall of the water tank 1, thus completing a flushing.

[0045] Then, the first driving motor 38 is controlled to drive the rotating shell 10 to rotate, thereby driving the first high-pressure nozzle 17 to rotate horizontally, and then the above flushing process is repeated until the entire wall surface of the water tank 1 is flushed.

[0046] When the flushing is finished, the disinfection cabinet inputs disinfectant into the temporary storage box 5, and repeats the above process to disinfect the inner wall of the water tank 1. After the disinfection is finished, continue to flush with clean water, and the water tank is cleaned after the flushing is finished.

[0047] This example adopts a semi-submerged installation, and the lower rotating shell 10 is set in the water tank 1, and the protection level meets IP54.

[0048] Correspondingly, the entire automatic cleaning device can also be placed in the water tank 1, in which case the protection level meets IP68.

[0049] Embodiment 2:

[0050] like Figure 1-10 As shown, on the basis of the first embodiment, the lower end of each first curved pipe 14 is fixedly connected to the first fixed block 21, the bottom of the first fixed block 21 is connected to the inner suction box 19, the inner suction box 19 is provided with a pumping cavity, the eccentric pump impeller 36 is rotatably arranged in the pumping cavity, the inner suction box 19 is provided with a water suction port 20 on the side away from the rotating tube 16, the water suction port 20 is connected to the pumping cavity, two second fixed blocks 25 are fixedly arranged on the rotating tube 16, the bottom of each second fixed block 25 is fixedly connected to the water spraying base 23, each water spraying base 23 is provided with a second high-pressure nozzle 24, and the inner suction box 19 is provided with two through ports on the side of the side close to the rotating tube 16, each through port is connected to the pumping cavity through the water passage 37, and each through port is connected to the corresponding water spraying base 23 through the hose 22. The water suction port 20 is connected to a floating pipe, which floats on the water surface inside the water tank 1. When the inner tube 13 drops to the lowest position, the floating pipe will not contact the bottom wall of the water tank 1.

[0051] Furthermore, the bottom of the inner tube 13 is rotatably connected to the fan blade shaft 35, one end of the fan blade shaft 35 passes through the upper wall of the inner suction box 19 and is fixedly connected to the eccentric pump impeller 36, and the impeller 34 is fixedly arranged at one end of the fan blade shaft 35 located inside the inner tube 13.

[0052] Furthermore, the second high-pressure nozzle 24 is inclined toward the first high-pressure nozzle 17 .

[0053] In this embodiment, when flushing the water tank 1, the water outflow speed of the sewage outlet 4 is controlled. When the water level in the water tank 1 drops to a certain level, the water outflow is stopped and cleaning begins.

[0054] When cleaning begins, high-pressure water flows into the impeller 34 inside the inner tube 13, driving the fan shaft 35 to rotate, and the fan shaft 35 drives the eccentric pump impeller 36 to rotate, thereby sucking water through the float tube. The water flows into the pump water chamber and then passes through the water passage 37 to the two water spray bases 23 and is sprayed out from the two second high-pressure nozzles 24.

[0055] The first high-pressure nozzle 17 and the second high-pressure nozzle 24 are flushed synchronously, and the inside of the water tank 1 that has been exposed by the lowering wall is rotated and cleaned. When the exposed wall is cleaned, the drain port 4 is opened, the water level continues to drop, and the rotation cleaning is continued. The above process is repeated until the water originally stored in the water tank 1 is discharged, and the cleaning of the top wall and the side wall of the water tank 1 has been completed. This setting can utilize the water stored in the water tank 1 during the cleaning process, saving at least 1 / 3 of the cleaning water.

[0056] After the side wall of the water tank 1 is cleaned, the bottom is flushed. At this time, the float tube droops. Since the accumulated water has been removed, the float tube begins to extract gas, and the gas is ejected from the second high-pressure nozzle 24. The first high-pressure nozzle 17 continues to spray water. After the high-pressure water hits the wall, the gas ejected from the second high-pressure nozzle 24 disperses the cleaned water and continues to expose the bottom wall, thereby avoiding the accumulation of water at the bottom of the water tank 1 during the flushing process, reducing the impact force of the high-pressure water gun, and the ejected gas can also help loosen the sediment attached to the bottom. Through the cooperation of air and water, the sludge at the bottom of the water tank 1 can be dispersed and discharged more efficiently and quickly.

[0057] In this embodiment, the disinfection process is similar to that in Embodiment 1 and will not be described in detail here.

[0058] The above is only a preferred implementation of the present application. Although the present application has been disclosed as a preferred embodiment, it is not intended to limit the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application still falls within the scope of protection of the technical solution of the present application.
