Description

Technical Field

[0001] This application relates to the field of water purification technology, and in particular to a self-purification device and method for garden water bodies. Background Technology

[0002] Gardens refer to specially cultivated natural environments and recreational areas, constructed through methods such as modifying the terrain, planting vegetation, building structures, and arranging garden paths. As an art form, gardens are widely distributed in my country.

[0003] In related technologies, a water self-purification device is designed, comprising a purification tank with an inlet pipe connected to one end. A motor and a filter assembly are installed inside the purification tank. The motor drives the filter assembly to rotate. An outlet pipe is connected to the end of the purification tank away from the inlet pipe, and the outlet pipe is connected to the filter assembly, which includes a filter element and a filter membrane wrapped around the filter element. A sewage pipe is connected to the bottom wall of the purification tank, and a solenoid valve is installed on the sewage pipe to open and close the sewage pipe. In practical applications, water enters the purification tank through the inlet pipe, is filtered by the filter assembly, and is discharged from the outlet pipe. When the motor drives the filter assembly to rotate, the solenoid valve opens the sewage pipe, thereby discharging the filtered sewage.

[0004] Regarding the aforementioned technologies, the inventors have discovered that to improve the aesthetics and cleanliness of garden landscapes, regular maintenance of the garden's internal landscape is usually necessary. Garden water bodies, as an important component, require focused maintenance. Therefore, purification devices are typically installed in garden water bodies to purify the water and keep it clear. However, trees are often planted around garden water bodies, and leaves frequently fall and float on the surface of the ponds. When using existing purification devices, larger debris such as leaves can enter the purification tank through the inlet pipe, causing blockages inside the purification device. This necessitates frequent maintenance and cleaning, resulting in numerous inconveniences, and therefore requires improvement. Summary of the Invention

[0005] In order to reduce the probability of debris such as leaves clogging the water purification device and reduce the maintenance frequency of the purification device, this application provides a self-purification device and method for garden water bodies.

[0006] Firstly, the self-purification device and method for garden water bodies provided in this application adopt the following technical solution:

[0007] A self-purification device for garden water bodies includes a purification tank disposed in a water body. The top wall of the purification tank is connected to a water inlet pipe. The end of the water inlet pipe opposite to the purification tank is connected to a filter cylinder. A water baffle cylinder is slidably connected to the outer wall of the water inlet pipe. The filter cylinder is located inside the water baffle cylinder. The top of the water baffle cylinder extends out of the water surface. A driving mechanism is provided on one side of the purification tank. The driving mechanism drives the water baffle cylinder to move up and down along the length of the water inlet pipe.

[0008] By adopting the above technical solution, the drive mechanism is activated, causing the baffle cylinder to sink below the water surface. Water then flows between the inner wall of the baffle cylinder and the outer wall of the filter cylinder. The water passes through the filter cylinder into the inlet pipe and the purification tank, while impurities remain between the inner wall of the baffle cylinder and the outer wall of the filter cylinder. This achieves the separation of water and impurities, thereby reducing the probability of the purification tank being clogged by impurities when filtering water. This improves the water purification efficiency, protects the structural safety of the purification tank, and extends its service life, resulting in high convenience and economic benefits.

[0009] Preferably, the bottom wall of the water-blocking cylinder is provided with a cleaning port, and a sewage pipe is connected to the outside of the cleaning port. The end of the sewage pipe opposite to the water-blocking cylinder is connected to a telescopic pipe, and the end of the telescopic pipe opposite to the sewage pipe is connected to a sewage tank. A cleaning component is provided inside the water-blocking cylinder, and the cleaning component is used to discharge debris between the water-blocking cylinder and the filter cylinder into the cleaning port.

[0010] By adopting the above technical solution, opening a cleaning port and setting up a cleaning component, impurities inside the water-blocking cylinder can be cleaned. On the one hand, by cleaning impurities, the probability of impurities clogging the mesh of the filter cylinder can be reduced, thereby allowing water flow to be unobstructed and helping to improve the efficiency of water purification. On the other hand, by cleaning the impurities inside the water-blocking cylinder, manual cleaning of the impurities inside the water-blocking cylinder is eliminated, enabling the purification device of this application to perform water purification work efficiently and for a longer period of time, which has high practicality and convenience.

[0011] Preferably, the cleaning assembly includes a rotating disk, a push plate, and a driving component. The rotating disk abuts against the end wall of the filter cylinder and the inlet pipe. The rotating disk has an outlet through which water enters the inlet pipe along its thickness direction. The push plate is connected to the peripheral wall of the rotating disk and abuts against both the inner wall of the baffle cylinder and the outer wall of the filter cylinder. The push plate covers the cleaning port. A baffle plate is connected to the inner wall of the end of the filter cylinder facing away from the inlet pipe. The driving component is connected to the bottom wall of the baffle plate. The output end of the driving component is connected to the rotating disk. The driving component drives the rotating disk and the push plate to rotate relative to the baffle cylinder. A fixing rod is provided on the top wall of the sewage tank. The end of the fixing rod facing away from the sewage tank extends out of the water surface. The end of the fixing rod extending out of the water surface is bent and connected to the baffle plate.

[0012] By adopting the above technical solution, when there is a lot of debris inside the water-blocking cylinder, the driving component is activated. The driving component drives the rotating disk and the push plate to rotate. After the push plate moves, the cleaning port will be exposed. When the push plate rotates, it will gradually push the debris between the inner wall of the water-blocking cylinder and the outer wall of the filter cylinder into the cleaning port, and further into the sewage tank through the sewage pipe, freeing up the space inside the water-blocking cylinder. This allows the purification device of this application to carry out long-term and efficient water purification work, reduces the frequency of cleaning the impurities inside the water-blocking cylinder by the staff, and has high practicality.

[0013] Preferably, the top wall of the sewage tank is provided with a corrugated pipe, the telescopic pipe is located inside the corrugated pipe, and the end of the corrugated pipe facing away from the sewage tank is connected to the outer wall of the sewage pipe.

[0014] By adopting the above technical solution, the corrugated pipe has extensibility. By setting the corrugated pipe on the outside of the telescopic pipe, it can achieve a waterproof effect, preventing external water from entering the sewage box through the gap between the outer and inner pipes of the telescopic pipe, thus effectively improving the sealing performance.

[0015] Preferably, the drain tank has a drain outlet on its side wall, a filter screen is installed inside the drain outlet, and a drain pipe is connected to the drain outlet. A first baffle, a second baffle, and a third baffle are sequentially installed on the inner wall of the drain pipe. The first baffle is located at the end of the drain pipe closest to the drain tank. A fixing block is installed on the surface of the third baffle, and a sliding groove is installed on the surface of the fixing block. The sliding groove is arranged in a closed loop, and a flow-limiting tube is slidably connected inside the sliding groove. A frustum is installed at the end of the flow-limiting tube away from the third baffle. A flow-limiting hole is opened through the first baffle along its thickness direction. The flow-limiting tube passes through the second baffle, and the side wall of the frustum abuts against the inner wall of the flow-limiting hole. An outlet tube is installed through the third baffle and inserted into the flow-limiting tube. A water inlet is opened on the outer wall of the flow-limiting tube between the first and second baffles. An elastic element is installed outside the outlet tube, and the elastic element drives the flow-limiting tube to slide away from the third baffle.

[0016] By adopting the above technical solution, some water will still accumulate on the surface of debris entering the sewage tank. As more debris enters the sewage tank, the water level will gradually increase. When the water level rises to the drain outlet, the excess water will flow out of the sewage tank through the drain outlet and drain pipe, thus saving space in the sewage tank and allowing it to hold more debris. The water entering the drain pipe will not be discharged directly. As the water level in the drain pipe increases, it will exert water pressure on the abutting truncated cone and the flow-limiting pipe. When the water pressure is high enough, it can offset the supporting force of the elastic element on the limiting pipe, thus controlling the abutting truncated cone and the flow-limiting pipe. The holes will no longer be in contact, and the water in the drain pipe will enter between the first and second baffles, and then be discharged from the drain pipe through the inlet hole and outlet pipe on the side wall of the flow-limiting pipe. The advantage of this structure is that the flow-limiting pipe and the elastic element can prevent external water from flowing back into the drain pipe, so that the water can only be discharged to the outside through the sewage tank. The water flows in one direction, which can maintain enough space in the sewage tank to store impurities, which helps to reduce the frequency of cleaning the sewage tank, reduce labor intensity, and extend the service life of the purification device of this application. It has high convenience and practicality.

[0017] Preferably, the end of the drain pipe away from the sewage tank is connected to a water collection tank, a water pump is installed in the water collection tank, the outlet of the water pump is connected to a return hose, and a flushing nozzle is installed on the inner wall of the drain pipe, the flushing nozzle being connected to the return hose.

[0018] By adopting the above technical solution, during sewage discharge, some debris may adhere to the inner wall of the sewage pipe due to the presence of water on its surface. Long-term adhesion will cause blockage of the sewage pipe, making it impossible for the water-blocking cylinder of this application to clean the internal debris. Manual cleaning is required in a timely manner. The water collection tank can reuse the water flowing into the sewage tank. The debris in the water collection tank is blocked by the filter screen and remains in the sewage tank, while the water can be pumped to the flushing nozzle through the water pump and return hose. The flushing nozzle can then repeatedly flush the inner wall of the sewage pipe, thereby keeping the sewage pipe unobstructed. This helps to reduce the maintenance frequency and has high practicality.

[0019] Preferably, the end wall of the outlet pipe extending out of the third baffle is hinged to a plurality of water-blocking plates, which are arranged in a closed loop. A reset member is provided at the hinge point between the water-blocking plate and the outlet pipe. The plurality of water-blocking plates close the outlet pipe under the drive of the corresponding reset member. Each water-blocking plate has a guide surface on its side wall, and the guide surfaces of adjacent water-blocking plates abut against each other.

[0020] By adopting the above technical solution, water baffles are installed on the bottom wall of the outlet pipe. Under the action of the reset component, several water baffles abut against each other, thereby sealing the outlet end of the outlet pipe. This prevents the water in the water tank from flowing back into the outlet pipe, or even the drain pipe and sewage tank, so that the water can only flow in one direction, which has a high degree of safety.

[0021] Preferably, the water-blocking cylinder is provided with a limiting edge on its peripheral wall, and the fixing rod passes through the limiting edge.

[0022] By adopting the above technical solution, setting a limiting edge, and allowing the fixing rod to pass through the limiting edge, the lifting path of the water baffle cylinder can be restricted, thereby improving the stability of the water purification device of this application during operation.

[0023] Preferably, the inner wall of the end of the water-blocking cylinder away from the purification tank has a flow-guiding surface, which is opened along the circumferential direction of the inner wall of the purification tank and is inclined towards the filter cylinder.

[0024] By adopting the above technical solution, a flow-guiding surface is opened on the inner wall of the water-blocking cylinder, so that when the water-blocking cylinder is submerged in the water, the water flow can enter between the water-blocking cylinder and the filter cylinder along the flow-guiding surface, making the water flow direction more regular and the water flow more gentle. This allows the water entering between the water-blocking cylinder and the filter cylinder to be filtered in a convenient way, which has high practicality.

[0025] Secondly, this application also provides a method for self-purification of garden water bodies, comprising the following steps:

[0026] The drive mechanism causes the water-blocking cylinder to sink below the water surface;

[0027] The water-blocking cylinder and the filter cylinder separate water from impurities;

[0028] The filtered water enters the purification tank through the inlet pipe for further purification.

[0029] The drive mechanism causes the water-blocking cylinder to extend out of the water surface;

[0030] Start the drive unit, which drives the rotating disk and the push plate to move. After the push plate moves, the cleaning port is exposed. The push plate pushes the impurities between the water baffle and the filter cylinder into the cleaning port. The impurities enter the sewage tank through the sewage pipe.

[0031] Water accumulated in the sewage tank enters the water collection tank through the drain outlet;

[0032] The water pump draws water from the water tank and transports it to the flushing nozzle through the return hose. The flushing nozzle sprays water onto the inner wall of the drain pipe to clean it.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The drive mechanism causes the baffle cylinder to sink below the water surface, and the water flow will enter between the inner wall of the baffle cylinder and the outer wall of the filter cylinder. The water will pass through the filter cylinder into the inlet pipe and the purification tank, while impurities will be left between the inner wall of the baffle cylinder and the outer wall of the filter cylinder, thus achieving the separation of water and impurities. This reduces the probability of the purification tank being blocked by impurities when filtering water, improves the water purification efficiency, protects the structural safety of the purification tank, and extends its service life, which has high convenience and economic benefits.

[0035] 2. The inclusion of a cleaning port and cleaning components allows for the removal of impurities from the water-blocking cylinder. On one hand, cleaning impurities reduces the probability of clogging the filter cylinder's mesh, ensuring smooth water flow and improving water purification efficiency. On the other hand, cleaning the impurities inside the water-blocking cylinder eliminates the need for manual cleaning, enabling the purification device to purify water efficiently and effectively over its lifespan, thus offering high practicality and convenience.

[0041] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0042] This application discloses a self-purification device for garden water bodies. (Refer to...) Figure 1 The system includes a purification tank 1 for purifying water, which is placed inside a water body. An inlet pipe 11 is connected to the top wall of the purification tank 1 and is vertically positioned. A filter cylinder 2 is installed at the end of the inlet pipe 11 facing away from the purification tank 1, and the filter cylinder 2 is below the water surface. A baffle cylinder 3 is slidably connected to the outer wall of the inlet pipe 11. The inlet pipe 11, filter cylinder 2, and baffle cylinder 3 are coaxially arranged, with the filter cylinder 2 located inside the baffle cylinder 3. The end of the baffle cylinder 3 facing away from the purification tank 1 extends beyond the water surface. A drive mechanism 31 is provided on one side of the tank 1. In this embodiment, the drive mechanism 31 includes a waterproof box and a cylinder. The piston rod of the cylinder extends out of the waterproof box and is connected to the outer wall of the water baffle 3 by welding, so that the water baffle 3 can be driven to extend or sink into the water surface. When the water baffle 3 sinks below the water surface, the water will flow into the space between the water baffle 3 and the filter cylinder 2. The filter cylinder 2 blocks impurities such as leaves and removes large impurities, thereby reducing the probability of the purification tank 1 being blocked, thereby improving the purification efficiency and extending the service life.

[0043] Reference Figure 1 The inner wall of the water-baffle cylinder 3, which is away from the purification tank 1, has a flow-guiding surface 34. The flow-guiding surface 34 is opened along the circumferential direction of the inner wall of the purification tank 1 and is inclined towards the filter cylinder 2. Thus, when the water flows into the water-baffle cylinder 3, it can flow in an orderly manner along the direction of the flow-guiding surface 34. As a result, the water flows from different directions will not have a large mutual influence, which helps to improve the filtration efficiency. In this embodiment, the bottom wall of the water-baffle cylinder 3 is set in a cone shape. Therefore, when the drive mechanism 31 drives it to sink, it can effectively reduce the resistance, protect the structural safety of the purification device of this application, and improve the operating efficiency.

[0044] Reference Figure 1The bottom wall of the water-blocking cylinder 3 has several cleaning ports 32, which are evenly distributed along the circumferential direction of the water-blocking cylinder 3. Each cleaning port 32 has a drain pipe 4 welded to its outer wall. The end of the drain pipe 4 facing away from the water-blocking cylinder 3 is connected to a telescopic pipe 41. In this embodiment, the telescopic pipe 41 includes an inner pipe and an outer pipe, with the inner pipe sliding inside the outer pipe. The telescopic pipe 41 is vertically positioned to accommodate the raising and lowering of the water-blocking cylinder 3. The outer pipe is welded to the drain pipe 4, and the inner pipe is welded to a useful... The top wall of the sewage tank 5, which stores impurities, is fitted with a corrugated pipe 42 by adhesive. The corrugated pipe 42 is sleeved on the outer wall of the telescopic pipe 41. The end of the corrugated pipe 42 facing away from the sewage tank 5 is connected to the outer wall of the sewage pipe 4 by adhesive, so that it can move with the telescopic pipe 41 when it extends and retracts. This prevents water in the water body from entering the sewage tank 5 through the gap between the inner and outer pipes of the telescopic pipe 41, improving the sealing performance and saving space inside the sewage tank 5 to accommodate more impurities.

[0045] Reference Figure 1 and Figure 2 The water-blocking cylinder 3 is equipped with a cleaning component 6 for cleaning impurities inside the water-blocking cylinder 3. The cleaning component 6 includes a rotating disk 61, several push plates 62 and a driving component 63, wherein the push plates 62 are arranged in a one-to-one correspondence with the cleaning port 32.

[0046] Reference Figure 1 and Figure 2 There is a gap between the filter cylinder 2 and the inlet pipe 11 for the rotating disk 61 to abut against. The rotating disk 61 abuts against the end wall of the baffle cylinder 3 and the inlet pipe 11 and can rotate freely. The top wall of the sewage tank 5 is connected by welding with four fixing rods 51. The fixing rods 51 are all vertically set. The end of the fixing rod 51 that is away from the sewage tank 5 extends out of the water surface. The outer wall of the baffle cylinder 3 is integrally formed with a limiting edge 33 in the circumferential direction. The fixing rods 51 pass through the limiting edge 33 to limit the lifting and lowering path of the baffle cylinder 3. The end of the fixing rod 51 that extends out of the water surface is connected to the filter cylinder 2 after multiple bends, thereby stabilizing the fixing cylinder.

[0047] Reference Figure 1 and Figure 2The rotating disk 61 has several water outlets 611 extending through its thickness to drain water from the filter cylinder 2 into the inlet pipe 11. Several push plates 62 are integrally formed on the peripheral wall of the rotating disk. The cross-section of each push plate 62 is consistent with the cross-section of the space between the filter cylinder 2 and the baffle cylinder 3, and abuts against the inner wall of the baffle cylinder 3 and the outer wall of the filter cylinder 2. When not rotating, each push plate 62 covers the surface of the corresponding cleaning port 32 to prevent water from entering the drain pipe 4. When the rotating disk 61 drives the push plate 62 to rotate, the cleaning port 32 will be exposed. Under the pushing action of the push plate 62, the debris between adjacent push plates 62 will enter the next cleaning port 32 and eventually enter the drain tank 5, thereby vacating the baffle cylinder 3 for efficient water filtration in the next round.

[0048] Reference Figure 1 and Figure 2 A baffle plate 21 is welded to the inner wall of the end of the filter cylinder 2 away from the water inlet pipe 11. In this embodiment, the driving component 63 is a motor. The stator of the driving component 63 is bolted to the bottom wall of the baffle plate 21. The rotor of the driving component 63 is connected to the rotating disk 61 through the transmission rod to drive the rotating disk 61 and the push plate 62 to rotate, thereby cleaning the impurities inside the baffle cylinder 3.

[0049] Reference Figure 1 The side wall of the sewage tank 5 is provided with several drain outlets 52. In this embodiment, the drain outlets 52 may not be provided on the side wall of the sewage tank 5 near the bottom. The water is discharged after it has accumulated to a certain depth. Each drain outlet 52 is provided with a filter screen 53 to prevent impurities in the sewage tank 5 from leaving the sewage tank 5.

[0050] Reference Figure 1 and Figure 3Each drain outlet 52 is externally connected to a drain pipe 54. The inner wall of the drain pipe 54 is sequentially fitted with a first baffle 541, a second baffle 542, and a third baffle 543, all welded together. The first baffle 541, second baffle 542, and third baffle 543 are all coaxially arranged vertically, with the first baffle 541 being closest to the drain outlet 52. A fixing block 55 is integrally formed on the surface of the third baffle 543. A sliding groove 551 is formed on the surface of the fixing block 55. The sliding groove 551 has a square closed-loop structure. A flow-limiting pipe 56, also a square pipe, is slidably connected within the sliding groove 551. The device can slide along the depth direction of the sliding groove 551. A discharge tube 57 is provided through the third baffle 543. The discharge tube 57 is inserted into the flow limiting tube 56 and communicates with the inside of the flow limiting tube 56. An elastic element 58 is sleeved on the periphery of the discharge tube 57. In this embodiment, the elastic element 58 is a spring. The spring is sleeved on the periphery of the discharge tube 57. One end of the elastic element 58 is glued to the surface of the third baffle 543. A guide post is integrally formed on the top wall of the inside of the flow limiting tube 56. The other end of the elastic element 58 is sleeved on the periphery of the guide post. Under the action of the elastic element 58, the flow limiting tube 56 always maintains the tendency to slide away from the third baffle 543.

[0051] Reference Figure 1 and Figure 3 The flow-limiting pipe 56 has a frustum 561 at one end away from the third baffle 543. The small-diameter end face of the frustum 561 is located away from the fixed block 55. The first baffle 541 has a flow-limiting hole 5411 extending through it along its thickness direction. The flow-limiting pipe 56 passes through the second baffle 542. When the elastic member 58 is not compressed, the side wall of the frustum 561 abuts against the inner wall of the flow-limiting hole 5411, thus preventing water from flowing from the direction of the third baffle 543 to the first baffle 541. The flow-limiting pipe 56 is located between the first baffle 541 and the second baffle 542. The wall is provided with several water inlet holes 562, which are evenly distributed along the circumference of the flow-limiting pipe 56. When there is a lot of water in the drain pipe 54, it will bring a large water pressure to the surface of the abutting frustum 561, causing the elastic element 58 to be compressed. The abutting frustum 561 and the inner wall of the flow-limiting hole 5411 will no longer be in contact, and the water in the drain pipe 54 will enter between the first baffle 541 and the second baffle 542, and then be discharged through the water inlet holes 562 and the outlet pipe 57. The design of this structure can prevent external water from flowing back while draining the accumulated water, and has high practicality.

[0052] Reference Figure 1The end of the drain pipe 54 away from the sewage tank 5 is connected to a water collection tank 7 to store the water discharged from the sewage tank 5. A water pump 71 is installed in the water collection tank 7. The outlet of the water pump 71 is connected to a return hose 72. The end of the return hose 72 away from the water pump 71 extends out of the water collection tank 7 and passes through the sewage pipe 4. A flushing nozzle 73 is installed on the inner wall of the sewage pipe 4. The return hose 72 is connected to the flushing nozzle 73, so that the water pump 71 can pump out the water in the water collection tank 7 and flush the inner wall of the sewage pipe 4, so that the impurities attached to the inner wall of the sewage pipe 4 can be washed off, thereby reducing the probability of the sewage pipe 4 being blocked.

[0053] Reference Figure 3 and Figure 4 Four water-blocking plates 571 are hinged to the bottom wall of the third baffle 543. In this embodiment, the cross-section of the four water-blocking plates 571 is triangular, and the side walls of the four water-blocking plates 571 are provided with guide surfaces 573 so that the four water-blocking plates 571 can abut against each other and form a square pyramid shape. A reset member 572 is provided at the hinge point between each water-blocking plate 571 and the third baffle 543. The reset member 572 is a torsion spring. One end of the reset member 572 is connected to the bottom wall of the third baffle 543 by adhesive, and the other end is connected to the water-blocking plate 571 by adhesive. Under the action of the reset member 572, the four water-blocking plates 571 abut against each other, thereby isolating the water collection tank 7 from the outlet pipe 57, so that water can only enter the water collection tank 7 through the outlet pipe 57, effectively improving the problem of water backflow in the water collection tank 7.

[0054] The implementation principle of the garden water self-purification device in this application embodiment is as follows: the water-blocking cylinder 3 is submerged below the water surface by the driving mechanism 31. At this time, the water flow will carry impurities such as leaves into the space between the water-blocking cylinder 3 and the filter cylinder 2. Under the obstruction of the filter cylinder 2, the impurities will remain in the water-blocking cylinder 3, while the water passes through the water-blocking cylinder 3 into the purification water tank for water purification. When there are a lot of impurities in the water-blocking cylinder 3, the cleaning component 6 can automatically clean the impurities inside the water-blocking cylinder 3 to free up the internal space of the water-blocking cylinder 3 for continuous water purification.

[0055] This application also discloses a method for self-purification of garden water bodies, including the following steps:

[0056] S1: Start the drive mechanism 31. The drive mechanism 31 drives the water baffle cylinder 3 to sink below the water surface, so that the water flows through the guide surface 34 of the water baffle cylinder 3 into the space between the inner wall of the water baffle cylinder 3 and the outer wall of the filter cylinder 2.

[0057] S2: The water-blocking cylinder 3 and the filter cylinder 2 separate water from impurities, so that large impurities such as leaves remain between the inner wall of the water-blocking cylinder 3 and the outer wall of the filter cylinder 2.

[0058] S3: The filtered water enters the purification tank 1 through the inlet pipe 11. The structure inside the purification tank 1 purifies the water. After purification, the water is discharged back into the water body.

[0059] S4: When a lot of impurities accumulate in the water-blocking cylinder 3, the drive mechanism 31 drives the water-blocking cylinder 3 to extend out of the water surface, and the water flow can no longer enter the water-blocking cylinder 3.

[0060] S5: Start the drive unit 63. The drive unit 63 drives the rotating disk 61 and the push plate 62 to move, so that the cleaning port 32 is exposed. During the rotation of the push plate 62, the push plate 62 pushes the impurities between the water baffle cylinder 3 and the filter cylinder 2 to move and enter the cleaning port 32. The impurities enter the sewage tank 5 through the sewage pipe 4, freeing up the internal space of the water baffle cylinder 3 so that the purification work can continue.

[0061] S6: The water accumulated in the sewage tank 5 enters the water collection tank 7 through the drain outlet 52;

[0062] S7: Water pump 71 draws water from the water tank 7 and transports it to the flushing nozzle 73 through the return hose 72. The flushing nozzle 73 sprays water to clean the inner wall of the drain pipe 4.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
