A first UV sterilizing lamp 6 is fixedly installed on the left inner wall of the first compartment 105, and a second UV sterilizing lamp 5 is fixedly installed on the right inner wall of the fifth compartment 104. Both the first UV sterilizing lamp 6 and the second UV sterilizing lamp 5 are used for water sterilization.

[0030] An electrical control box 11 is fixedly installed on the top left side of the filter box 100. A filter screen barrel 8 connected to the first chamber 105 is rotatably installed on the right side of the first partition 10. A rotary drive assembly fixedly connected to the left side of the filter screen barrel 8 is fixedly installed on the inner right side of the electrical control box 11. A timer switch 13 electrically connected to the rotary drive assembly is fixedly installed on the inner right side of the electrical control box 11. A round filter screen is fixedly connected to the inside of the filter screen barrel 8.

[0031] The second compartment 101 is fixedly installed with a rinsing assembly that cooperates with the filter screen barrel 8. The rear inner wall of the fourth compartment 103 is fixedly installed with a first solenoid valve 4 that is connected and fixed to the rinsing assembly. The right end of the first solenoid valve 4 extends to the outside of the filter box 100. The first solenoid valve 4 is electrically connected to the timer switch 13.

[0032] Multiple water passages are provided on the top of one side of the second partition 2. Both the third compartment 102 and the fourth compartment 103 are equipped with bacterial houses, each consisting of a box-shaped filter screen and nitrifying bacteria filled within it. Horizontally mounted support filter plates are fixedly installed in both the third compartment 102 and the fourth compartment 103, with the bacterial houses placed on the corresponding support filter plates. An inlet pipe 15, connected to the inside of the first compartment 105, is fixedly connected to the left side of the filter box 100. An outlet pipe 20, connected to the fifth compartment 104, is fixedly connected to the right side of the filter screen barrel 8. A drain pipe 14 is rotatably connected to the right side of the filter screen barrel 8. A through hole is provided on the right side of the filter screen barrel 8, and a sealed bearing is fixedly fitted inside the through hole. The inner ring of the sealed bearing is fixedly fitted to the outer side of the drain pipe 14, allowing the filter screen barrel 8 to be rotatably installed on the right side. One end of the drain pipe 14 extends outside the filter box 100, and a second solenoid valve is installed on the drain pipe 14. The inlet pipe 15 is used to draw water from the fishpond from the outside. After the water pump outlet is connected, the water supply is introduced into the first chamber 105. The filter screen 8 is used to allow the water in the first chamber 105 to enter and filter out the garbage in the water on its inner side, thus creating a filtration effect. The filtered water flows into the third chamber 102 and is purified by the bacteria house on the left side. Then it gradually passes through the third partition 3 and enters the fourth chamber 103 for further purification. The fifth chamber 104 is used to allow the water after the two purifications to flow out. The water outlet pipe 20 is used to connect to the fish pond through an external pipe and return the water after the two purifications to the fish pond for continued use. The rotary drive assembly is used to drive the filter screen 8 to rotate at a timer controlled by the timer switch 13. The flushing assembly is used to backwash the rotating filter screen 8 after the first solenoid valve 4 is connected to an external water supply pipe or other pressure water supply pipe, and when the first solenoid valve 4 is controlled by the timer switch 13 to open, it cleans the rotating filter screen 8. The sewage pipe 14 and the second solenoid valve are used to guide the sewage from the backwashing outward when the timer switch 13 is opened.

[0033] Specifically, the rotary drive assembly includes a reducer 12 fixedly installed on the inner right side of the electrical control box 11 and electrically connected to the timer switch 13. The output shaft of the reducer 12 extends into the second compartment 101 and is fixedly connected to a first sprocket. A second sprocket 9 is fixedly connected to the left side of the filter screen barrel 8. The second sprocket 9 and the first sprocket are connected by the same chain. The reducer 12, the first sprocket, the second sprocket 9 and the chain work together. When the timer switch 13 is turned on, the reducer 12 drives the first sprocket to rotate. The first sprocket drives the second sprocket 9 to rotate through the chain. The rotation of the second sprocket 9 achieves the effect of driving the filter screen barrel 8 to rotate.

[0034] Furthermore, the flushing assembly includes a U-shaped mounting bracket 702 fixedly installed on the right side of the first partition 10. The bottom right side of the U-shaped mounting bracket 702 is fixedly connected to the top of the drain pipe 14. Two connecting rods are fixedly connected to the rear side of the U-shaped mounting bracket 702. The rear ends of the two connecting rods are fixedly connected to the same horizontal pipe 701 with a sealing structure on the left end. The front side of the horizontal pipe 701 is connected to and fixedly connected to multiple high-pressure nozzles 7 that are inclined towards the filter screen barrel 8. A baffle 17 located above the multiple high-pressure nozzles 7 is fixedly installed on the top of the U-shaped mounting bracket 702. An explosion-proof hose is fixedly connected between the right end of pipe 701 and the left end of the first solenoid valve 4. The U-shaped fixing bracket 702, connecting rod, horizontal pipe 701, explosion-proof hose, high-pressure nozzle 7 and guard cover 17 are configured to work together. After the first solenoid valve 4 is connected to an external water supply pipeline such as tap water, and when the first solenoid valve 4 is controlled by the timer switch 13 to open, external pressurized water is supplied into the horizontal pipe 701 through the first solenoid valve 4, and then sprayed onto the rotating filter screen 8 through multiple high-pressure nozzles 7, so as to achieve the effect of backflushing and cleaning the rotating filter screen 8 from the outside to the inside.

[0035] Furthermore, a cover plate 16 is rotatably mounted on the top rear side of the filter box 100 via two hinges. Hydraulic telescopic rods 18 are hinged between the upper part of the inner walls on both sides of the filter box 100 and the bottom of the cover plate 16. The cover plate 16 is used to cover the top of the filter box 100 during use, and the hydraulic telescopic rods 18 are used to support the cover plate 16 after it is rotated upwards and flipped open.

[0036] Furthermore, a guide pipe 19 is fixedly installed at the bottom of the filter box 100. The left end of the guide pipe 19 extends to the outside of the filter box 100 and is threaded with a sealing cap. Three drainage pipes are integrally connected to the outside of the guide pipe 19. The three drainage pipes are respectively connected and fixed to the bottom of the first chamber 105, the second chamber 101 and the third chamber 102. Rubber plugs are movably inserted at the top of the two drainage pipes on the left side. Multiple communication holes are opened at the bottom of one side of the third partition 3 for connecting the third chamber 102 and the fourth chamber 103. The guide pipe 19, drainage pipes, sealing caps and rubber plugs are designed to allow personnel to remove the sealing caps and rubber plugs during subsequent deep cleaning to drain the water remaining in the lower inner part of the first chamber 105, the second chamber 101, the third chamber 102 and the fourth chamber 103, so as to facilitate subsequent internal inspection and maintenance work.

[0037] Furthermore, a support bearing is fixedly connected to the right side of the first partition 10, and a rotating tube is fixedly sleeved inside the inner ring of the support bearing. The right end of the rotating tube is connected and fixed to the left side of the filter screen barrel 8. A circular through hole connected to the inner side of the rotating tube is opened on the left side of the first partition 10, which serves to support the rotation of the filter screen barrel 8.

[0038] This embodiment can sterilize, purify and filter garbage and impurities in the fish pond water in two steps, and can automatically backwash, clean and drain the filter screen 8 at regular intervals, eliminating the need for manual garbage removal, which facilitates routine cleaning and maintenance, saves time and effort and improves ease of use.

[0039] The usage method of this embodiment is as follows: When using the fully automatic fish pond filter, connect the inlet pipe 15 to the outlet of the external water pump that draws water from the fish pond, so that the water in the fish pond can be drawn and supplied to the first chamber 105. Connect the outlet pipe 20 to the fish pond through an external pipe. Connect the first solenoid valve 4 to an external water supply pipe such as a tap. After the water from the fish pond is introduced into the first chamber 105, the water is initially sterilized by the first UV sterilizing lamp 6. The water after initial sterilization continues to enter the filter screen barrel 8. The round filter screen inside the filter screen barrel 8 filters the water... The waste filter intercepts the waste on its inner side, forming a filtration effect on the water. The filtered water flows into the third chamber 102 and is consumed by nitrifying bacteria in the bacterial house on the left. At the same time, the toxic ammonia nitrogen in the water is converted into non-toxic nitrate by the nitrifying bacteria, achieving a preliminary purification effect. The water then gradually passes through the third partition 3 and enters the fourth chamber 103, where it is purified again by the bacterial house. The water after two stages of purification enters the fifth chamber and is sterilized again by the second UV sterilizing lamp 5. Then, it is discharged back into the fish pond through the outlet pipe 20 for reuse, achieving the effect of filtering and purifying the water in the fish pond.

[0040] The opening and closing times of the reducer 12, the first solenoid valve 4, and the second solenoid valve are pre-set using a timer switch 13 according to the on-site cleaning needs. When the cleaning time is reached, the timer switch 13 controls the reducer 12, the first solenoid valve 4, and the second solenoid valve to open. When the reducer 12 opens, it drives the first sprocket to rotate. The first sprocket drives the second sprocket 9 to rotate via a chain. The second sprocket 9 drives the filter screen barrel 8 to rotate. After the first solenoid valve 4 opens, external pressurized water is supplied into the horizontal pipe 701. The water is then sprayed onto the rotating filter screen barrel 8 through multiple high-pressure nozzles 7, achieving comprehensive cleaning of the rotating filter screen barrel 8 from the outside in. The flushing and cleaning process effectively removes wastewater and impurities through the drain pipe 14 and the second solenoid valve. Personnel can pre-guide the external end of the drain pipe 14 to the external sewage discharge area via an external pipe. When the closing time is reached, the timer switch 13 controls the reducer 12, the first solenoid valve 4, and the second solenoid valve to close, and waits for the next cleaning time to open again for cleaning, dredging, and sewage discharge. This achieves the effect of automatically backflushing, cleaning, dredging, and discharging sewage from the filter screen bucket 8 at set times, eliminating the need for personnel to manually remove and clean the garbage. This facilitates routine cleaning and maintenance, saves time and effort, and improves ease of use.

[0041] In addition, when subsequent maintenance is required inside the filter box 100, personnel can remove the sealing pipe cover and rubber plug to allow the water remaining in the lower inner part of the first compartment 105, the second compartment 101, the third compartment 102 and the fourth compartment 103 to be discharged through the drain pipe 19, thus avoiding the impact of excessive water residue on maintenance and repair work and providing greater convenience for subsequent maintenance and repair work.

[0042] Example 2

[0043] The difference between this embodiment and embodiment one is that, without using the timer switch 13, a liquid level sensor switch is also fixedly installed on the inner left side of the first chamber 105, and the reducer 12 and the first solenoid valve 4 are both electrically connected to the liquid level sensor switch.

[0044] This embodiment, without utilizing the timer switch 13, can automatically backwash, clean, unclog, and discharge sewage by monitoring water level changes caused by blockages, achieving the effect of automatic opening and closing based on water level changes, and providing another form of automatic cleaning and sewage discharge.

[0045] The method of use in this embodiment is as follows: The difference from embodiment one is that, without using the timer switch 13, the liquid level sensor switch is used to sense the liquid level in the first chamber 105 in real time to control the opening and closing of the operation. Specifically, during filtration, when the round filter screen inside the filter screen barrel 8 is blocked, causing poor or no water flow, as water enters the first chamber 105, the water level in the first chamber 105 gradually rises because it cannot be filtered and discharged in time. The liquid level sensor switch detects the water level and controls the reducer 12, the first solenoid valve 4 and the second solenoid valve to automatically open when the water level reaches the preset value, so as to carry out automatic backflushing, cleaning, dredging and sewage discharge. As the cleaning continues to make the filtration smooth, the water level drops. When the liquid level sensor switch detects that the water level is lower than the preset value, it controls the reducer 12, the first solenoid valve 4 and the second solenoid valve to automatically close. This achieves the effect of automatic opening and closing according to the water level change for cleaning and dredging, providing another form of automatic cleaning and sewage discharge, which is convenient for personnel to flexibly select and apply according to on-site needs.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
