[0010] Preferably, the filter cylinder is made of stainless steel.

[0011] Preferably, the water inlet pipe is a metal corrugated hose.

[0012] In a second aspect, the present invention further provides a method for using the submersible pump water inlet cleaning system according to any one of the above technical solutions, comprising the following steps: S1, the buoyancy adjustment assembly drives the filter cylinder to float to the horizontal plane; S2, the first driving assembly drives the outer ring blade to rotate at a first speed, and the second driving assembly drives the inner ring blade to rotate at a second speed, wherein the first speed is equal to the second speed; S3, starting the drainage pump, the first water flow is ejected from the first drainage hole, the second water flow is ejected from the second drainage hole, and opposite water flows are formed in the filter hole to clean the inner wall of the filter hole; S4.

[0014] (III) Beneficial effects The above technical solution of the present invention has at least the following advantages: 1. In the present invention, the first driving assembly drives the outer ring blade to move along the outer circumference of the filter cylinder, and the blade of the outer ring blade can cut the debris on the outer circumference of the filter cylinder, so that the debris is separated from the outer circumference of the filter cylinder; the second driving assembly drives the inner ring blade to rotate along the inner circumference of the filter cylinder, and the blade of the inner ring blade can cut the debris on the inner circumference of the filter cylinder, so that the debris is separated from the inner circumference of the filter cylinder. This prevents debris from covering the filter holes on the filter cylinder, thereby increasing the water intake of the filter cylinder and improving the working efficiency of the submersible pump.

[0015] 2. In the present invention, the outer ring blade and the inner ring blade are relatively arranged on both sides of the filter cylinder and operate in a first working state, that is, the drainage pumps of the outer ring blade and the inner ring blade can provide a certain power to allow water to pass through the first drainage channel and eject from the first drainage hole to form a first water flow, and at the same time allow water to pass through the second drainage channel and eject from the second drainage hole to form a second water flow. In the first working state, the first speed of rotation of the outer ring blade is equal to the second speed of rotation of the inner ring blade, that is, the inner ring blade and the outer ring blade rotate synchronously along the circumference of the filter cylinder, and the first drainage hole on the outer ring blade and the second drainage hole on the inner ring blade move synchronously in real time. When the first drainage hole moves to the corresponding area of ​​the filter hole on the outer peripheral side, and the second drainage hole moves to the corresponding area of ​​the filter hole on the inner peripheral side, the first water flow and the second water flow form a counter-flowing water flow inside the filter hole. The counter-flowing of the first water flow and the second water flow generates an explosive force, which can clean the debris adhered to the inner wall of the filter hole, so that the debris is separated from the inner wall of the filter hole. In the second working state, the third speed of the outer ring blade is not equal to the fourth speed of the inner ring blade. At this time, the outer ring blade and the inner ring blade no longer move synchronously, but move in a staggered manner. The first water flow can pass through the filter hole from the outside to the inside along the radial direction of the filter cylinder, and the second water flow can pass through the filter hole from the inside to the outside along the radial direction of the filter cylinder to flush out the debris detached from the filter hole, thereby further cleaning the inner wall of the filter hole. At the same time, in the first working state and the second working state, when the outer ring blade and the inner ring blade move to the area where the filter hole is not located, they can clean the inner and outer sides of the filter cylinder, thereby flushing the detached debris from the inner and outer sides of the filter cylinder, and cleaning the filter cylinder through water flow impact.

[0016] 3. In the present invention, by adjusting the buoyancy of the buoyancy adjustment component, the filter cylinder is suspended in the water area to avoid direct contact with the mud at the bottom of the water area, to avoid direct suction of the mud into the submersible pump, thereby damaging the submersible pump and prolonging its service life.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating relative importance or indicating the number of technical features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments: like Figures 1 to 7As shown, an embodiment of the present invention provides a submersible pump water inlet cleaning system, including a submersible pump 1, a filter cylinder 2, an outer ring blade 3, an inner ring blade 4, a first drive assembly 5, a second drive assembly 6, a water storage tank 7 and a buoyancy adjustment assembly 8; the submersible pump 1 has an inlet pipe 11 and a drain pipe 12; the filter cylinder 2 is connected to the water inlet of the inlet pipe 11, and has a plurality of filter holes 21; the outer ring blade 3 is attached to the outer peripheral side of the filter cylinder 2, and has a first drainage channel 31 that is interconnected and a plurality of first drainage holes 32 corresponding to the positions of the plurality of filter holes 21; the inner ring blade 4 is attached to the inner side of the filter cylinder 2 The outer ring blade 3 is connected to the outer ring blade 4, and is used to drive the outer ring blade 3 to rotate along the outer circumference of the filter cylinder 2; the second driving assembly 6 is connected to the inner ring blade 4, and is used to drive the inner ring blade 4 to rotate along the inner circumference of the filter cylinder 2; a drainage pump (not shown) is provided inside the water storage tank 7, and the outlet of the drainage pump is connected to the first drainage channel 31 and the second drainage channel 41 respectively; the buoyancy adjustment assembly 8 is connected to the bottom of the filter cylinder 2, and is used to drive the filter cylinder 2 to float or sink. Specifically, in this embodiment, the outer ring blade 3 and the inner ring blade 4 are preferably blades with equal arc lengths. Specifically, the filter cylinder 2 is a hollow cylindrical structure, and the structures of the outer ring blade 3 and the inner ring blade 4 are similar. The outer ring blade 3 is taken as an example for explanation. The blade is arranged on one side or both sides of the outer ring blade 3 along the circumferential direction of the filter cylinder 2. The length of the blade is equal to or slightly less than the height of the filter cylinder 2, and the shape of the blade is arc-shaped. The blade of the outer ring blade 3 fits the outer peripheral side of the filter cylinder 2. Similarly, the blade of the inner ring blade 4 fits the inner peripheral side of the filter cylinder 2. For the middle part of the outer ring blade 3 and the inner ring blade 4, it can fit with the filter cylinder 2, or maintain a certain gap with the filter cylinder 2 to facilitate the discharge of water during cleaning.

[0030] Furthermore, the top surface of the water storage tank 7 is preferably provided with a water inlet hole, and when the filter drum 2 sinks into the water area, the water in the water area can enter the water storage tank 7 through the water inlet hole to replenish the water stored in the water storage tank 7. It should be noted that the water inlet hole is only provided on the top surface of the water storage tank in a direction perpendicular to the horizontal plane, and when the filter drum 2 sinks, water can enter the water storage tank 7 under the action of gravity and can be stored in the water storage tank 7.

[0031] Furthermore, in order to realize the automatic control of the cleaning process, the submersible pump water inlet cleaning system also includes a control module and a power supply. The control module is electrically connected to the first drive component 5, the second drive component 6, the drainage pump and the buoyancy adjustment component 8. Specifically, the control module is built with relevant control programs for controlling the opening and closing of the above components and adjusting the operating parameters of the above components. The algorithm program involved in the control program is common knowledge known to those skilled in the art, and this application will not repeat it. The power supply is electrically connected to the first drive component 5, the second drive component 6, the drainage pump and the buoyancy adjustment component 8, respectively, to power their work. It should be noted that since the working environment of this embodiment is in the water area, the control module and the power supply should be selected from components that can work normally in the water area and should have a waterproof function.

[0032] In one embodiment, the filter cylinder 2 includes a cylinder body 22 and an outer slide groove 23, a plurality of filter holes 21 are formed on the cylinder body 22, the outer slide groove 23 is connected to the cylinder body 22, and the outer ring blade 3 is slidably connected to the outer slide groove 23. Specifically, the groove width of the outer slide groove 23 matches the thickness of the outer ring blade 3 (slightly larger than its thickness) to limit the thickness direction of the outer ring blade 3, thereby preventing it from shaking greatly during operation, thereby ensuring stable operation.

[0033] In one embodiment, the filter cylinder 2 includes a cylinder body 22 and an inner slide groove (not shown), a plurality of filter holes 21 are formed on the cylinder body 22, the inner slide groove is connected to the cylinder body 22, and the inner ring blade 4 is slidably connected to the inner slide groove. Specifically, the groove width of the inner slide groove matches the thickness of the inner ring blade 4 (slightly larger than its thickness) to limit the thickness direction of the inner ring blade 4, thereby preventing it from shaking greatly during operation, thereby ensuring stable operation.

[0034] In one embodiment, the buoyancy adjustment assembly includes a buoyancy cylinder 81, a solenoid valve (not shown), an exhaust pipe 82 and a gas generating device (not shown), the buoyancy cylinder 81 is connected to the exhaust pipe 82, the solenoid valve is arranged on the exhaust pipe 82, and the gas generating device is connected to the buoyancy cylinder 81. Specifically, the gas generating device includes but is not limited to an oxygen generating device capable of generating oxygen, a hydrogen generating device capable of generating hydrogen, and a gas generating device capable of generating other gases. The generation of oxygen or hydrogen can be achieved by electrolysis of water or by other means. The gas generating device is common knowledge to those skilled in the art, and this application will not elaborate on it. Specifically, when the filter cylinder 2 needs to be submerged in water, the electromagnetic valve can be controlled to open, and the exhaust pipe 82 is connected to the external atmospheric environment at this time, and the gas in the buoyancy cylinder 81 overflows into the external atmospheric environment through the exhaust pipe 82. After the gas in the buoyancy cylinder 81 is discharged (specifically, a pressure sensor can be set in the buoyancy cylinder 81 to detect the air pressure in the buoyancy cylinder 81 to determine whether the gas in the buoyancy cylinder 81 is discharged), the electromagnetic valve is controlled to close to close the exhaust pipe 82. At this time, under the action of the self-weight of the submersible pump water inlet cleaning system, the filter cylinder 2 sinks; conversely, when the filter cylinder needs to float, the electromagnetic valve is closed, the gas generating device is started, and when the gas generated by the gas generating device fills the buoyancy cylinder (specifically, a pressure sensor can be set in the buoyancy cylinder 81 to detect the air pressure in the buoyancy cylinder 81 to determine whether the gas in the buoyancy cylinder 81 is full), the filter cylinder 2 floats under the buoyancy generated by the buoyancy cylinder. Furthermore, the gas generating device, the air pressure sensor and the solenoid valve are electrically connected to the above-mentioned control module to realize automatic control of the buoyancy adjustment component 8. If necessary, a water pump can be arranged in the buoyancy cylinder 81, and the water pump is connected to a water pumping pipe, and a corresponding water pumping solenoid valve is arranged on the water pumping pipe. The water pump can pump water into the buoyancy cylinder to increase the deadweight of the buoyancy cylinder, thereby facilitating the sinking of the filter cylinder 2. Similarly, the water pump can also discharge the water in the buoyancy cylinder through the water pumping pipe. This process is carried out simultaneously with the process of the gas generating device pumping gas into the buoyancy cylinder, that is, draining water while inflating to increase the buoyancy of the buoyancy cylinder and realize the floating of the filter cylinder 2. In another embodiment, the buoyancy adjustment component 8 can also be a rotor arranged above the filter cylinder 2, and the lifting of the filter cylinder 2 is realized by driving the rotor to rotate. In another embodiment, the buoyancy adjustment component 8 may also be a propeller disposed below the filter cartridge 2, and the filter cartridge 2 is lifted by the power provided by the propeller, and the filter cartridge 2 is sunk by shutting down the propeller.

[0035] In one embodiment, the first driving assembly 5 includes a first motor 51 and a first connecting rod 52, the first motor 51 is connected to the filter cylinder 2, and the first connecting rod 52 connects the output end of the first motor 51 and the outer ring blade 3. Specifically, the first connecting rod 52 is a hollow structure, and a first water supply channel for water flow is formed therein, and the first water supply channel is connected to the first drainage channel 31. More specifically, the water supply pipeline connected to the water storage tank 7 and the output shaft of the first motor 51 are coaxially arranged.

[0036] In one embodiment, the second driving assembly 6 includes a second motor 61 and a second connecting rod 62, the second motor 61 is connected to the filter cylinder 2, and the second connecting rod 62 connects the output end of the second motor 61 and the inner ring blade 4. Specifically, the second connecting rod 62 is a hollow structure, in which a second water supply channel for water flow is formed, and the second water supply channel is connected to the second drainage channel 41. More specifically, the water supply pipeline connected to the water storage tank 7 is coaxially arranged with the output shaft of the second motor 61.

[0037] In one embodiment, the filter cylinder 2 is made of stainless steel. Stainless steel has relatively good corrosion resistance and structural strength, which can increase its service life in aquatic environments.

[0038] In one embodiment, the water inlet pipe 11 is a metal corrugated hose, which can be extended and retracted to a certain length and rotated in a certain direction, and can cooperate with the buoyancy adjustment component 8 to realize the floating or sinking of the filter cylinder 2.

[0039] In a second aspect, the present invention further provides a method for using the submersible pump water inlet cleaning system of any one of the above technical solutions, comprising the following steps: S1, the buoyancy adjustment assembly 8 drives the filter cylinder 2 to float to the horizontal plane; S2, the first driving assembly 5 drives the outer ring blade 3 to rotate at a first speed, and the second driving assembly 6 drives the inner ring blade 4 to rotate at a second speed, wherein the first speed is equal to the second speed; S3. Start the drainage pump, the first water flow A is ejected from the first drainage hole 32, the second water flow B is ejected from the second drainage hole 42, and opposite water flows are formed in the filter hole to clean the inner wall of the filter hole 21; specifically, the width of the inner ring blade 4 is preferably set to cover the single row of filter holes 21 on the filter cylinder 2, and similarly, the width of the outer ring blade 3 is also preferably set to cover the single row of filter holes 21 on the filter cylinder 2. When the outer ring blade 3 and the inner ring blade 4 rotate synchronously, when both move to the next row of filter holes 21, the water in the previous row of filter holes 21 can flow out. Furthermore, the drainage pump preferably pumps water in a pulse pumping mode, that is, the drainage pump pumps water once at a preset time interval, and the water is ejected in a point-by-point manner to avoid the water pressure of the continuous ejection of water from exerting a continuous force on the outer ring blade 3, the inner ring blade 4 and the filter cylinder 2, causing them to deform; S4, the buoyancy adjustment assembly 8 drives the filter cylinder 2 to sink below the horizontal plane.

[0040] In one embodiment, before step S4, the following steps are also included: the first driving component 5 drives the outer ring blade 3 to rotate at a third speed, and the second driving component 6 drives the inner ring blade 4 to rotate at a fourth speed, wherein the third speed is not equal to the fourth speed.

[0041] The working principle of this embodiment is as follows: It should be noted that the filter cylinder 2 in the present application is suspended in the water area by adjusting the buoyancy of the buoyancy adjustment component 8 when it is in working state (pumping water from the placement area), so as to avoid direct contact with the sediment at the bottom of the water area and avoid directly pumping the sediment into the submersible pump to damage the submersible pump. When cleaning is required, first increase the buoyancy provided by the buoyancy adjustment component 8 so that the filter cylinder 2 floats to the horizontal surface of the water area and exposes the filter cylinder 2 to the air. At this time, the submersible pump does not work. Then, start the first drive component 5, and the first drive component 5 drives the outer ring blade 3 to move along the outer peripheral side of the filter cylinder 2. The blade of the outer ring blade 3 can cut the debris on the outer peripheral side surface of the filter cylinder 2 (including but not limited to growing water plants, algae, and leaves adsorbed on the surface, etc.), so that the debris is detached from the outer peripheral side surface of the filter cylinder 2. At the same time, the second drive assembly 6 is started, and the second drive assembly 6 drives the inner ring blade 4 to rotate along the inner circumference of the filter cylinder 2. The blade of the inner ring blade 4 can cut the debris on the inner circumference of the filter cylinder 2, so that the debris is separated from the inner circumference of the filter cylinder 2. After the outer ring blade 3 and the inner ring blade 4 are driven to rotate a certain number of times (in this embodiment, it is preferred to drive both to rotate 3 times), the drainage pump in the water storage tank 7 is started, and the drainage pump pumps the water in the water storage tank 7 to the first drainage channel 31 and the second drainage channel 41. First, the outer ring blade 3 and the inner ring blade 4 are arranged on both sides of the filter cylinder 2 and operate in the first working state, that is, the drainage pumps of the outer ring blade 3 and the inner ring blade 4 can provide a certain power to make water pass through the first drainage channel 31 and eject from the first drainage hole 32 to form a first water flow A, and at the same time make water pass through the second drainage channel 41 and eject from the second drainage hole 42 to form a second water flow B. In the first working state, the first speed of the outer ring blade 3 is equal to the second speed of the inner ring blade 4, that is, the inner ring blade 4 and the outer ring blade 3 rotate along the filter cylinder 2. The first drainage hole 32 on the outer ring blade 3 and the second drainage hole 42 on the inner ring blade 4 move synchronously in real time. When the first drainage hole 32 moves to the corresponding area on the outer peripheral side of the filter hole 21, and the second drainage hole 42 moves to the corresponding area on the inner peripheral side of the filter hole 21, the first water flow A and the second water flow B form a counter-flowing water flow inside the filter hole 21. The first water flow A and the second water flow B generate an explosive force, which can clean the debris adhered to the inner wall of the filter hole 21 and make the debris detach from the inner wall of the filter hole 21. Further, as Figure 8As shown, a drainage groove 33 may be provided on the outer ring blade 3, and the drainage groove 33 is connected to a plurality of first drainage holes 32, so that the water can flow out along the drainage groove 33 after the water jets are cleaned. Similarly, in another embodiment, a drainage groove may be provided on the inner ring blade 4, and the drainage groove is connected to a plurality of second drainage holes, so that the water can flow out along the drainage groove 33 after the water jets are cleaned. It should be noted that the drainage groove may be provided only on the inner ring blade 4 or the outer ring blade 3, or may be provided on both the inner ring blade 4 and the outer ring blade 3. After working for a certain period of time in the first working state (the specific time can be set according to actual use requirements), the outer ring blade 3 and the inner ring blade 4 are switched to the second working state, that is, the third speed of the outer ring blade 3 is not equal to the fourth speed of the inner ring blade 4. At this time, the outer ring blade 3 and the inner ring blade 4 no longer move synchronously, but move in a staggered manner. In the second working state, the first water flow A can be ejected from the outside to the inside through the filter hole along the radial direction of the filter cylinder 2, and the second water flow B can be ejected from the inside to the outside through the filter hole 21 along the radial direction of the filter cylinder 2, so as to flush out the debris detached from the filter hole and further clean the inner wall of the filter hole. At the same time, in the first working state and the second working state, when the outer ring blade 3 and the inner ring blade 4 move to the area where the non-filter hole 21 is located, they can clean the inner and outer sides of the filter cylinder 2 to flush out the detached debris from the inner and outer sides of the filter cylinder. After cleaning is completed, the buoyancy adjustment assembly 8 is controlled to drive the filter cylinder to sink to a preset height below the horizontal plane, and then the submersible pump is started to work.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
