Description

Technical Field

[0001] This invention relates to the field of submersible pump technology, and more specifically, to a submersible pump inlet cleaning system and its usage method. Background Technology

[0002] Currently, submersible pumps are widely used in various industries due to their small size, light weight, and ease of movement and installation. However, for submersible pumps that need to be used in fixed water areas for extended periods, the inlet area is prone to the growth of aquatic plants, algae, or the accumulation of debris such as leaves and plants. This can affect the pump's performance. In particular, if these plants are sucked into the pump body, it can damage the pump, reduce its lifespan, cause losses for the user, and disrupt normal production. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem that this invention aims to solve is that the inlet of existing submersible pumps is easily blocked by debris, or debris is easily absorbed into the interior of the submersible pump, causing damage to the pump.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides a submersible pump inlet cleaning system, comprising a submersible pump, a filter cylinder, an outer ring blade, an inner ring blade, a first drive assembly, a second drive assembly, a water storage tank, and a buoyancy adjustment assembly; the submersible pump has an inlet pipe and a drain pipe; the filter cylinder is connected to the inlet of the inlet pipe and has multiple filter holes; the outer ring blade is attached to the outer periphery of the filter cylinder and has a first drainage channel communicating with each other and multiple first drainage holes corresponding to the positions of the multiple filter holes; the inner ring blade is attached to the inner periphery of the filter cylinder and has a second drainage channel communicating with each other and multiple second drainage holes corresponding to the positions of the multiple filter holes; the first drive assembly is connected to the outer ring blade and is used to drive the outer ring blade to rotate along the outer periphery of the filter cylinder; the second drive assembly is connected to the inner ring blade and is used to drive the inner ring blade to rotate along the inner periphery of the filter cylinder; a drain pump is provided inside the water storage tank, and the outlet of the drain pump is connected to the first drainage channel and the second drainage channel respectively; the buoyancy adjustment assembly is connected to the filter cylinder and is used to drive the filter cylinder to float or sink.

[0008] Preferably, the filter cylinder includes a cylinder body and an outer sliding groove. The cylinder body has multiple filter holes, the outer sliding groove is connected to the cylinder body, and the outer ring blade is slidably connected to the outer sliding groove.

[0009] Preferably, the filter cylinder includes a cylinder body and an inner sliding groove. The cylinder body has multiple filter holes, the inner sliding groove is connected to the cylinder body, and the inner ring blade is slidably connected to the inner sliding groove.

[0010] Preferably, the buoyancy adjustment assembly includes a buoyancy cylinder, a solenoid valve, an exhaust pipe, and a gas generating device. The buoyancy cylinder is connected to the exhaust pipe, the solenoid valve is located on the exhaust pipe, and the gas generating device is connected to the buoyancy cylinder.

[0011] Preferably, the first drive assembly includes a first motor and a first connecting rod, the first motor being connected to the filter cylinder, and the first connecting rod connecting the output end of the first motor to the outer ring blade.

[0012] Preferably, the second drive assembly includes a second motor and a second connecting rod, the second motor being connected to the filter cylinder, and the second connecting rod connecting the output end of the second motor to the inner ring blade.

[0013] Preferably, the filter cylinder is made of stainless steel.

[0014] Preferably, the water inlet pipe is a corrugated metal hose.

[0015] Secondly, the present invention also provides a method of using the submersible pump inlet cleaning system described in any one of the above technical solutions, comprising the following steps:

[0016] S1. The buoyancy adjustment component drives the filter cylinder to float to the horizontal plane;

[0017] S2. The first driving component drives the outer ring blade to rotate at a first speed, and the second driving component drives the inner ring blade to rotate at a second speed, wherein the first speed is equal to the second speed;

[0018] S3-1. Start the drain pump. The first water flow is ejected from the first drain hole, and the second water flow is ejected from the second drain hole, forming a counter-flow of water within the filter hole to clean the inner wall of the filter hole.

[0019] S4. The buoyancy adjustment component drives the filter cylinder to sink below the horizontal plane.

[0020] Preferably, before step S4, the method further includes the following steps: S3-2, the first driving component drives the outer ring blade to rotate at a third speed, and the second driving component drives the inner ring blade to rotate at a fourth speed, wherein the third speed and the fourth speed are not equal.

[0021] (III) Beneficial Effects

[0022] The above-described technical solution of the present invention has at least the following advantages:

[0023] 1. In this invention, the first driving assembly drives the outer ring blade to move along the outer periphery of the filter cylinder. The cutting edge of the outer ring blade can cut debris on the outer periphery surface of the filter cylinder, causing the debris to detach from the outer periphery surface. The second driving assembly drives the inner ring blade to rotate along the inner periphery of the filter cylinder. The cutting edge of the inner ring blade can cut debris on the inner periphery surface of the filter cylinder, causing the debris to detach from the inner periphery surface. This prevents debris from blocking 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.

[0024] 2. In this invention, the outer ring blade and the inner ring blade are arranged opposite each other 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 make water pass through the first drainage channel and be ejected from the first drainage hole to form a first water flow. At the same time, water passes through the second drainage channel and is ejected 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. 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 on the outer periphery of the filter hole and the second drainage hole moves to the corresponding area on the inner periphery of the filter hole, the first water flow and the second water flow form a counter-flow inside the filter hole. The first water flow and the second water flow generate explosive force through counter-flow, which can clean the debris adhering to the inner wall of the filter hole and make the debris detach from the inner wall of the filter hole. In the second working state, the third speed of the outer ring blade rotation is not equal to the fourth speed of the inner ring blade rotation. At this time, the outer and inner ring blades no longer move synchronously, but rather in a staggered motion. The first water flow can pass through the filter holes radially along the filter screen cylinder and exit from the outside to the inside, while the second water flow can pass through the filter holes radially along the filter screen cylinder and exit from the inside to the outside. This flushes out any debris that has detached from the filter holes, further cleaning the inner wall of the filter holes. Simultaneously, in both the first and second working states, when the outer and inner ring blades move to areas outside the filter holes, they can clean the inner and outer circumferences of the filter screen cylinder, flushing away any detached debris. The cleaning of the filter screen cylinder is achieved through the impact of the water flow.

[0025] 3. In this invention, by adjusting the buoyancy of the buoyancy adjustment component, the filter screen cylinder is suspended in the water to avoid direct contact with the mud and sand at the bottom of the water, thus preventing the mud and sand from being directly pumped into the submersible pump and causing damage to the submersible pump, thereby extending its service life.

[0037] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments:

[0041] like Figures 1 to 7As shown, this embodiment of the invention provides a submersible pump 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 inlet of the inlet pipe 11 and has multiple filter holes 21; the outer ring blade 3 is attached to the outer periphery of the filter cylinder 2 and has a first drainage channel 31 that is interconnected with each other and multiple first drainage holes 32 that correspond to the positions of the multiple filter holes 21; the inner ring blade 4 is attached to the inner periphery of the filter cylinder 2. The filter cylinder 2 has interconnected second drainage channels 41 and multiple second drainage holes 42 corresponding to the positions of multiple filter holes 21. A first drive assembly 5 is connected to the outer ring blade 3 and drives the outer ring blade 3 to rotate along the outer periphery of the filter cylinder 2. A second drive assembly 6 is connected to the inner ring blade 4 and drives the inner ring blade 4 to rotate along the inner periphery of the filter cylinder 2. A drainage pump (not shown) is installed 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. A buoyancy adjustment assembly 8 is connected to the bottom of the filter cylinder 2 and drives 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. The outer ring blade 3 and the inner ring blade 4 have similar structures. Taking the outer ring blade 3 as an example, its cutting edge is located on one or both sides along the circumference of the filter cylinder 2. The length of the cutting edge is equal to or slightly less than the height of the filter cylinder 2, and the shape of the cutting edge is arc-shaped. The cutting edge of the outer ring blade 3 is attached to the outer circumference of the filter cylinder 2. Similarly, the cutting edge of the inner ring blade 4 is attached to the inner circumference of the filter cylinder 2. The middle part of the outer ring blade 3 and the inner ring blade 4 can be attached to the filter cylinder 2 or maintain a certain gap with the filter cylinder 2 to facilitate water drainage during cleaning.

[0042] Furthermore, the top surface of the water storage tank 7 is preferably provided with a water inlet hole. When the filter screen cylinder 2 sinks into the water area, water in the water area can enter the interior of 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 opened on the top surface of the water storage tank in the direction perpendicular to the horizontal plane. When the filter screen cylinder 2 sinks, water can enter the interior of the water storage tank 7 under the action of gravity and be stored inside the water storage tank 7.

[0043] Furthermore, to achieve automated control of the cleaning process, the submersible pump 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 drain pump, and the buoyancy adjustment component 8. Specifically, the control module has a built-in control program for controlling the opening and closing of the aforementioned components and adjusting their operating parameters. The algorithm involved in this control program is common knowledge known to those skilled in the art, and will not be described in detail here. The power supply is electrically connected to the first drive component 5, the second drive component 6, the drain pump, and the buoyancy adjustment component 8 to provide power for their operation. It should be noted that, since the working environment of this embodiment is in water, the control module and the power supply should be selected from components that can operate normally in water and should have waterproof functionality.

[0044] In one embodiment, the filter cylinder 2 includes a cylinder body 22 and an outer sliding groove 23. The cylinder body 22 has multiple filter holes 21. The outer sliding groove 23 is connected to the cylinder body 22, and the outer ring blade 3 is slidably connected to the outer sliding groove 23. Specifically, the width of the outer sliding groove 23 matches the thickness of the outer ring blade 3 (slightly greater than its thickness) to limit the thickness direction of the outer ring blade 3, preventing it from shaking significantly during operation and ensuring stable operation.

[0045] In one embodiment, the filter cylinder 2 includes a cylinder body 22 and an inner groove (not shown). The cylinder body 22 has multiple filter holes 21. The inner groove is connected to the cylinder body 22, and the inner ring blade 4 is slidably connected to the inner groove. Specifically, the width of the inner groove matches the thickness of the inner ring blade 4 (slightly greater than its thickness) to limit the thickness direction of the inner ring blade 4, preventing significant shaking during operation and ensuring stable operation.

[0046] 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 located 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 producing oxygen, a hydrogen generating device capable of producing hydrogen, and a gas generating device capable of producing other gases. The production of oxygen or hydrogen can be achieved through water electrolysis or other methods. Gas generating devices are common knowledge to those skilled in the art, and will not be described in detail here. Specifically, when the filter cylinder 2 needs to be submerged in water, the solenoid valve can be opened, connecting the exhaust pipe 82 to the outside atmosphere. Gas inside the buoyancy cylinder 81 overflows into the atmosphere through the exhaust pipe 82. Once the gas in the buoyancy cylinder 81 has been completely discharged (specifically, a pressure sensor inside the buoyancy cylinder 81 can be used to detect the pressure and determine if the gas has been discharged), the solenoid valve is closed to shut off the exhaust pipe 82. At this point, the filter cylinder 2 sinks under its own weight. Conversely, when the filter cylinder needs to float, the solenoid valve is closed, and the gas generator is activated. When the gas generated by the gas generator fills the buoyancy cylinder (specifically, a pressure sensor inside the buoyancy cylinder 81 can be used to detect the pressure and determine if the buoyancy cylinder 81 is full), the filter cylinder 2 floats under the buoyancy generated by the buoyancy cylinder. Furthermore, the gas generator, pressure sensor, and solenoid valve are electrically connected to the aforementioned control module to achieve automated control of the buoyancy adjustment component 8. If necessary, a water pump can be installed inside the buoyancy cylinder 81, connected to a suction pipe with a corresponding suction solenoid valve. The pump can pump water into the buoyancy cylinder to increase its weight, thus facilitating the sinking of the filter cylinder 2. Similarly, the pump can also drain water from the buoyancy cylinder through the suction pipe. This process occurs simultaneously with the gas generator pumping gas into the buoyancy cylinder, i.e., draining water while simultaneously filling with gas to increase the buoyancy of the cylinder and allow the filter cylinder 2 to float. In another embodiment, the buoyancy adjustment component 8 can also be a rotor positioned above the filter cylinder 2, which lifts the filter cylinder 2 by driving its rotation. In another embodiment, the buoyancy adjustment component 8 can also be a propeller located below the filter cylinder 2, which provides power to lift the filter cylinder 2 and turns the filter cylinder 2 down by turning off the propeller.

[0047] In one embodiment, the first drive 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 to the outer ring blade 3. Specifically, the first connecting rod 52 has a hollow structure with a first water supply channel formed inside for water flow, which is connected to the first drainage channel 31. More specifically, the water supply pipe connected to the water storage tank 7 and the output shaft of the first motor 51 are coaxially arranged.

[0048] In one embodiment, the second drive 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 to the inner ring blade 4. Specifically, the second connecting rod 62 has a hollow structure with a second water supply channel formed inside for water flow, which is connected to the second drainage channel 41. More specifically, the water supply pipe connected to the water storage tank 7 and the output shaft of the second motor 61 are coaxially arranged.

[0049] In one embodiment, the filter cylinder 2 is made of stainless steel. Stainless steel has excellent corrosion resistance and structural strength, which can improve its service life in aquatic environments.

[0050] In one embodiment, the water inlet pipe 11 is a corrugated metal hose. The corrugated metal hose can extend and retract to a certain length and rotate in direction, and can be used in conjunction with the buoyancy adjustment component 8 to make the filter cylinder 2 float or sink.

[0051] Secondly, the present invention also provides a method of using the submersible pump inlet cleaning system of any of the above-mentioned technical solutions, comprising the following steps:

[0052] S1. The buoyancy adjustment component 8 drives the filter cylinder 2 to float to the horizontal plane;

[0053] S2. The first drive assembly 5 drives the outer ring blade 3 to rotate at a first speed, and the second drive assembly 6 drives the inner ring blade 4 to rotate at a second speed, wherein the first speed is equal to the second speed.

[0054] S3-1. Start the drain pump. The first water flow A is ejected from the first drain hole 32, and the second water flow B is ejected from the second drain hole 42, forming a counter-current water flow within the filter holes 21 to clean the inner wall of the filter holes 21. Specifically, the width of the inner ring blade 4 is preferably designed to cover a single row of filter holes 21 on the filter screen cylinder 2, and similarly, the width of the outer ring blade 3 is also preferably designed to cover a single row of filter holes 21 on the filter screen cylinder 2. When the outer ring blade 3 and the inner ring blade 4 rotate synchronously, the water in the previous row of filter holes 21 can flow out when they move to the next row of filter holes 21. Further, the drain pump preferably pumps water in a pulse pumping mode, that is, the drain pump pumps water once at a preset time interval, and the water is ejected in a point-jet manner to avoid the continuous force exerted by the water pressure of the continuously ejected water on the outer ring blade 3, the inner ring blade 4, and the filter screen cylinder 2, which would cause deformation.

[0055] S4. The buoyancy adjustment component 8 drives the filter cylinder 2 to sink below the horizontal plane.

[0056] In one embodiment, the following steps are included before step S4: S3-2, 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 and the fourth speed are not equal.

[0057] The working principle of this embodiment is as follows:

[0058] It should be noted that, in the working state (pumping water into the placement area), the filter cylinder 2 in this application is suspended in the water by adjusting the buoyancy of the buoyancy adjustment component 8, thus avoiding direct contact with the sediment at the bottom of the water and preventing the sediment from being directly pumped into the submersible pump and damaging it. When cleaning is required, the buoyancy provided by the buoyancy adjustment component 8 is first increased, causing the filter cylinder 2 to float to the water surface and be exposed to the air. At this time, the submersible pump is not working. Then, the first drive component 5 is activated, which drives the outer ring blade 3 to move along the outer periphery of the filter cylinder 2. The blades of the outer ring blade 3 can cut debris (including but not limited to growing aquatic plants, algae, and leaves adhering to the surface) on the outer periphery of the filter cylinder 2, causing the debris to detach from the outer periphery of the filter cylinder 2. Simultaneously, the second drive assembly 6 is activated, driving the inner ring blade 4 to rotate along the inner circumference of the filter cylinder 2. The cutting edge of the inner ring blade 4 can cut the debris on the inner circumference surface of the filter cylinder 2, causing the debris to detach from the inner circumference surface of the filter cylinder 2. After driving the outer ring blade 3 and the inner ring blade 4 to rotate a certain number of times (in this embodiment, it is preferable to drive both to rotate 3 times), the drain pump in the water storage tank 7 is activated, pumping the water in the water storage tank 7 to the first drain channel 31 and the second drain channel 41. First, the outer ring blade 3 and the inner ring blade 4 are arranged opposite each other on both sides of the filter cylinder 2 and operate in a 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 be ejected from the first drainage hole 32, forming a first water flow A. At the same time, water passes through the second drainage channel 41 and is ejected from the second drainage hole 42, forming a second water flow B. In the first working state, the first speed of rotation of the outer ring blade 3 is equal to the second speed of rotation 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 outer ring blade 3 and the inner ring blade 4 rotate synchronously in the circumferential direction. The first drain hole 32 on the outer ring blade 3 and the second drain hole 42 on the inner ring blade 4 move synchronously in real time. When the first drain hole 32 moves to the corresponding area on the outer circumference of the filter hole 21 and the second drain hole 42 moves to the corresponding area on the inner circumference of the filter hole 21, the first water flow A and the second water flow B form opposing water flows inside the filter hole 21. The opposing water flows A and B generate explosive force, which can clean the debris adhering to the inner wall of the filter hole 21, allowing the debris to detach from the inner wall of the filter hole 21. Further, as Figure 8As shown, a drainage groove 33 can be provided on the outer ring blade 3, and the drainage groove 33 is connected to multiple first drainage holes 32 to facilitate the outflow of water along the drainage groove 33 after the anti-jet water cleaning is completed. Similarly, in another embodiment, a drainage groove can be provided on the inner ring blade 4, and the drainage groove is connected to multiple second drainage holes to facilitate the outflow of water along the drainage groove 33 after the anti-jet water cleaning is completed. It should be noted that the drainage groove can be provided only on the inner ring blade 4 or the outer ring blade 3, or it can be provided on both the inner ring blade 4 and the outer ring blade 3. After operating for a certain period of time in the first working state (the specific time can be set according to actual usage requirements), the outer ring blade 3 and inner ring blade 4 are switched to the second working state. In this second working state, the third rotational speed of the outer ring blade 3 is not equal to the fourth rotational speed of the inner ring blade 4. At this time, the outer ring blade 3 and inner ring blade 4 no longer move synchronously but rather in a staggered motion. In the second working state, the first water flow A can pass through the filter holes radially along the filter cylinder 2 and exit from the outside to the inside, while the second water flow B can pass through the filter holes 21 radially along the filter cylinder 2 and exit from the inside to the outside, thus flushing out any detached debris from the filter holes and further cleaning the inner wall of the filter holes. Simultaneously, in both the first and second working states, when the outer ring blade 3 and inner ring blade 4 move to areas other than the filter holes 21, they can clean the inner and outer circumferences of the filter cylinder 2, thus flushing away any detached debris from the inner and outer circumferences of the filter cylinder. After cleaning is completed, control the buoyancy adjustment component 8 to drive the filter cylinder to sink to the preset height below the horizontal plane, and then start the submersible pump to work.

[0059] 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 within the protection scope of the present invention.
