[0002] During surface water irrigation, due to impurities in the water, a filtration device is usually required at the water pump intake. However, existing filtration structures are often directly installed at the intake. This results in excessive resistance at the intake due to blockage by impurities and the small mesh size of the filter screen. Furthermore, the lack of a buffer structure at the intake point can easily lead to poor water intake. Utility Model Content

[0003] The purpose of this utility model is to provide a floating island filter with low water intake resistance, thereby solving the technical problems of poor water intake and the impact of the filter on the pump suction head in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A floating island filter with low water intake resistance includes: a frame, in which a filter cartridge is mounted via a filter cartridge main shaft at the center of the frame. The filter cartridge main shaft is a static shaft. One side of the filter cartridge along its length is located inside a storage tank. A side wall of the storage tank divides the filter cartridge along its length into an inlet section and a storage section. A sealing structure is provided at the separation point between the inlet and storage sections of the filter cartridge on the side wall of the storage tank. A support plate with a flow channel is fixedly installed between the mating surfaces of the inlet and storage sections of the filter cartridge. The support plate is connected to the filter cartridge main shaft. The filter cartridge is installed by rotating the bearing. The circumference of the inlet section filter cartridge is the inlet area. The liquid enters the inlet section filter cartridge from the outside to the inside from the inlet area. Then, it passes through the support plate flow channel and enters the storage section filter cartridge. Then, it flows from the inside to the outside from the storage section filter cartridge and gathers downwards into the storage tank under the action of gravity. The upper two sides of the frame are provided with float plates, which make the entire filter suspend in water. In the natural state, part of the filter cartridge is exposed above the liquid surface. The lower part of the storage tank has a water pump interface, which is connected to a water pump.

[0005] This utility model discloses a floating island filter with low water intake resistance. The end of the inlet section filter cartridge is closed, and the end of the inlet section filter cartridge is rotatably connected to the filter cartridge main shaft via a bearing. The end of the storage section filter cartridge is an open, unclosed structure. An end sealing ring is provided on the inner circumference of the open end of the storage section filter cartridge. A fixed end plate is provided at a corresponding position on the inner circumference of the end sealing ring. The fixed end plate is fixedly connected to the filter cartridge main shaft. The fixed end plate has a crescent-shaped structure and a notch at the upper part. A C-shaped soft pad is fitted on the outer circumference of the fixed end plate. The outer circumference of the C-shaped soft pad contacts the inner side of the end sealing ring and can rotate relative to it to achieve a seal at the rolling connection.

[0006] This utility model discloses a floating island filter with low water intake resistance. The inlet section filter cartridge is equipped with an inlet section filter cartridge flushing assembly inside, and the storage section filter cartridge is equipped with a storage section filter cartridge flushing assembly outside. Both the inlet section filter cartridge flushing assembly and the storage section filter cartridge flushing assembly are connected to a high-pressure water pipe.

[0007] This utility model discloses a floating island filter with low water intake resistance. The liquid storage section filter cartridge has a sludge guide groove inside, corresponding to the position of the liquid storage section filter cartridge flushing component, and the sludge guide groove extends to the outside of the liquid storage section filter cartridge.

[0008] This utility model discloses a floating island filter with low water intake resistance. The filter cylinder is uniformly provided with external drive blades on its outer circumference. The external drive blades of the inlet section filter cylinder and the storage section filter cylinder are staggered. An external flushing drive nozzle assembly is provided on one side of the outer circumference of the filter cylinder along its length direction. The external flushing drive nozzle assembly is connected to a high-pressure water pipe. The external flushing drive nozzle assembly sprays water to impact the external drive blades, causing the filter cylinder to rotate.

[0009] This utility model discloses a floating island filter with low water intake resistance. The side wall of the support plate is provided with blades. The blades are driven by the water flow to make the support plate rotate around the main shaft of the filter cylinder, thereby making the filter cylinder rotate.

[0010] This utility model discloses a floating island filter with low water intake resistance. The filter cartridge has a mechanical drive structure in the middle. The mechanical drive structure includes a drive wheel, which is connected to a power device. The drive wheel meshes with a driven wheel, which is installed on the outer circumference of the filter cartridge.

[0011] This utility model discloses a floating island filter with low water intake resistance. The inner circumference of the end sealing ring of the filter cartridge in the liquid storage section is supported by a support wheel. The support wheel is connected to the frame through a support frame. The lower part of the end of the filter cartridge has a rolling sealing structure between it and the inner wall of the liquid storage tank.

[0012] This utility model discloses a floating island filter with low water intake resistance, wherein the liquid storage tank is provided with several operating holes with filter screens on the side or bottom.

[0013] The beneficial effects of this utility model are as follows: It proposes a floating island filter with low water intake resistance. During the water pump intake process, float plates on both sides of the frame ensure the entire device maintains the required liquid level. The sealed structure of the storage tank divides the filter cartridge into an inlet section and a storage section. Liquid enters the inlet section filter cartridge from the outside in through the filter screen, flows through the support plate with flow channels, and enters the storage section filter cartridge. The liquid level difference generated by the pump drawing liquid from the storage tank causes the liquid to flow from the inside out through the filter screen of the storage section filter cartridge into the storage tank, achieving a filtration effect. Because the storage section filter cartridge is located at the top of the storage tank, sufficient water collection space is formed around and below it. Since the top of the storage tank is not sealed, the storage tank... Negative pressure is not generated within the filter body, thus reducing or eliminating the water intake resistance of the filtration device. Flushing devices are installed in the inlet and storage sections of the filter cartridge to wash away impurities, and a guide channel is used to guide the impurities washed down from the storage section to the outside of the filter cartridge. Blades on the sidewall of the support plate flow channel rotate the filter cartridge under the influence of the water level difference, improving the filtration effect. The combination of an external flushing nozzle assembly and external drive blades allows for further increases in the rotation speed of the filter cartridge through the impact of high-pressure water. A mechanical drive structure enables relatively low-power rotation of the filter cartridge via a motor and transmission system. An operating port allows for cleaning of the storage tank when needed.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-7As shown, a floating island filter with low water intake resistance includes: a frame 100, on which a filter cartridge 200 is supported and installed via a filter cartridge main shaft 201 in the middle of the frame 100. The filter cartridge main shaft 201 is a static shaft. One side of the filter cartridge 200 along its length is located inside a storage tank 120. One side wall of the storage tank 120 divides the filter cartridge 200 along its length into an inlet section filter cartridge 210 and a storage section filter cartridge 220. A sealing structure is provided at the separation point between the inlet section filter cartridge 210 and the storage section filter cartridge 220 on the side wall of the storage tank 120. A support plate 240 with a flow channel is fixedly provided between the mating surfaces of the inlet section filter cartridge 210 and the storage section filter cartridge 220. The support plate 240 and the filter cartridge... The main shafts 201 are rotatably mounted via bearings. The inlet section filter cartridge 210 has an inlet area 110 around its circumference. Liquid enters the inlet section filter cartridge 210 from the outside to the inside from the inlet area, and then passes through the flow channel of the support plate 240 from the inlet section filter cartridge 210 into the storage section filter cartridge 220. Then, from the inside to the outside, the liquid flows downward from the storage section filter cartridge 220 into the storage tank 120 under the action of gravity. The upper two sides of the frame 100 are provided with float plates 130, which suspend the entire filter in water. In a natural state, a part of the filter cartridge 200 is exposed above the liquid surface. The lower part of the storage tank 120 has a water pump interface 122, which is connected to a water pump.

[0018] It should be noted that the frame 100 is a frame structure with supporting legs at the bottom. The filter cartridge 200 is located in the upper middle part. Under the action of the float plate 130, part of the filter cartridge 200 is positioned above the water surface. The structure formed by the float plate 130 and the frame can block floating objects around the filter cartridge 200 from the outside. By setting an arc-shaped groove and a sealing structure, such as a flexible sealing ring, at the junction of the side wall of the storage tank 120 and the filter cartridge 200, the water flow around the filter cartridge 210 in the inlet section cannot enter the storage tank 120 through the gap between the side wall of the storage tank 120 and the filter cartridge 200. Furthermore, the rotation of the filter cartridge 200 is not affected. In short, it is a rotary sealing structure.

[0019] In a preferred embodiment of this utility model, the end of the inlet section filter cartridge 210 is closed, and the end of the inlet section filter cartridge 210 is rotatably connected to the filter cartridge main shaft 201 via a bearing. The end of the storage section filter cartridge 220 is an open, unclosed structure. An end sealing ring 222 is provided on the inner side of the open end of the storage section filter cartridge 220. A fixed end plate 223 is provided at a corresponding position on the inner circumference of the end sealing ring 222. The fixed end plate 223 is fixedly connected to the filter cartridge main shaft 201. The fixed end plate 223 has a crescent-shaped structure and a notch at the top. A C-shaped soft pad 224 is fitted on the outside of the fixed end plate 223. The outer circumference of the C-shaped soft pad 224 contacts the inner side of the end sealing ring 222 and can rotate relative to it to achieve a seal at the rolling connection.

[0020] It should be noted that, as Figure 2 and Figure 7 As shown, the end plate of the inlet section filter cartridge 210 is a closed structure, and a filter screen is provided on the end plate to allow liquid to enter. The end plate and the filter cartridge main shaft 201 are rotatably connected by a bearing. The end of the storage section filter cartridge 220 is an open structure. The fixed end plate 223 and the end sealing ring 222 rotate relative to each other and achieve dynamic sealing at the joint. The fixed end plate 223 is fitted with a C-shaped soft pad 224. The snap-fit ​​of the C-shaped soft pad 224 is engaged and fixed with the fixed end plate 223. The end sealing ring 222 rotates with the storage section filter cartridge 220, that is, the inner side of the C-shaped soft pad 224 and the end sealing ring 222 achieve dynamic sealing. The fixed end plate 223 has a notch at the top, so that the end of the storage section filter cartridge 220 is not completely closed. This structure allows the structure such as the storage section guide groove 221 to extend into the cartridge body, so that it is not interfered with during rotation.

[0021] In a preferred embodiment of this utility model, an inlet section filter cartridge flushing assembly 600 is provided inside the inlet section filter cartridge 210, and a storage section filter cartridge flushing assembly 400 is provided outside the storage section filter cartridge 220. Both the inlet section filter cartridge flushing assembly 600 and the storage section filter cartridge flushing assembly 400 are connected to a high-pressure water pipe.

[0022] It should be noted that, as mentioned above, part of the filter cartridge 200 is located above the water surface to facilitate the cleaning of impurities adhering to the surface of the filter cartridge. Since the filter cartridge 200 is rotating, uniform and continuous rinsing is achieved. The rinsing direction of the rinsing components is opposite to the direction of water flow. For example, the inlet section filter cartridge rinsing component 600 rinses from the inside to the outside, while the storage section filter cartridge rinsing component 400 rinses from the outside to the inside.

[0023] In a preferred embodiment of the present invention, a liquid storage section guide groove 221 is provided inside the liquid storage section filter cartridge 220 at a position corresponding to the position of the liquid storage section filter cartridge flushing assembly 400, and the liquid storage section guide groove 221 extends to the outside of the liquid storage section filter cartridge 220.

[0024] In a preferred embodiment of this utility model, the filter cartridge 200 is uniformly provided with external driving blades 230 on its outer periphery, and the external driving blades 230 of the liquid inlet section filter cartridge 210 and the liquid storage section filter cartridge 220 are staggered. An external flushing drive nozzle assembly 300 is provided on one side of the filter cartridge 200 along its length direction. The external flushing drive nozzle assembly 300 is connected to a high-pressure water pipe, and the external flushing drive nozzle assembly 300 sprays water to impact the external driving blades 230, causing the filter cartridge 200 to rotate.

[0025] In a preferred embodiment of this utility model, the side wall of the support plate 240 is provided with blades 241. The blades 241 are driven by the water flow to rotate the support plate 240 around the filter cartridge main shaft 201, thereby causing the filter cartridge 200 to rotate.

[0026] This structural support plate also provides support for the middle part of the filter cartridge 200. The sidewall of the support plate's flow channel is equipped with blades, which are driven by the water flow to rotate the support plate, thereby causing the filter cartridge 200 to rotate. This structure can utilize the flow force generated by the water level difference to drive the filter cartridge 200 to rotate, achieving rotation of the filter cartridge 200 without external power in some cases.

[0027] In a preferred embodiment of this invention, the filter cartridge 200 has a mechanical drive structure 500 in its middle. The mechanical drive structure 500 includes a drive wheel 510 connected to a power device. The drive wheel 510 meshes with a driven wheel 520, which is mounted on the outer circumference of the filter cartridge 200. This structure allows the filter cartridge 200 to rotate using a relatively low-power drive device, thus enabling auxiliary rotation using a lower safety voltage.

[0028] In a preferred embodiment of this utility model, the inner circumference of the end sealing ring 222 at the end of the liquid storage section filter cartridge 220 is supported by a support wheel 150. The support wheel 150 is connected to the frame 100 through a support frame 140. This structure can provide auxiliary support for the liquid storage section filter cartridge 220 and reduce the axial force on the main shaft. The end sealing ring 222 and the fixed end plate 223 have a dynamic sealing structure. It should be noted that the upper part of the fixed end plate 223 has an open structure. This structure ensures that the liquid storage section filter cartridge 220 will not interfere with the liquid storage section guide groove 221 during rotation. The fixed end plate 223 is fixedly connected to the filter cartridge main shaft 201. The fixed end plate 223 and the end sealing ring 222 have a dynamic sealing structure in the circumferential direction, so that the liquid in the liquid storage section filter cartridge 220 can only enter the liquid storage tank 120 through the filter screen in the circumferential direction of the liquid storage section filter cartridge 220.

[0029] In a preferred embodiment of this utility model, the liquid storage tank 120 is provided with a plurality of operating holes 121 with filters on its side or bottom to achieve the functions of pressure relief, sewage discharge and gravity buffering.

[0030] Application examples: such as Figure 6 As shown, the water intake pipe 810 of the water intake pump 800 is connected to the water pump interface 122, and the entire floating island filter is placed in the target water area. A flushing pump 900 is also installed. The flushing pump inlet pipe 910 of the flushing pump 900 can have several connection structures: one is connected to the outlet pipe 820 of the water intake pump 800, and another is connected to the storage tank 120. The flushing pump outlet pipe 920 is connected to multiple pipelines via an automatic control valve, respectively connecting to the external flushing drive nozzle assembly 300, the storage section filter cartridge flushing assembly 400, and the supply section flushing assembly 600, providing high-pressure water flow. The water from the target water area enters its interior through the forward filtration of the inlet section filter cartridge 210, flows through the flow channel of the support plate 240 to the storage section filter cartridge 220. The water flows from the inside to the outside of the storage tank 120 through the filter cartridge 220 in the inlet section. During this process, the filter cartridge 220 performs reverse filtration from the inside to the outside. Both the filter cartridge 210 in the inlet section and the filter cartridge 220 in the storage section rotate during this process, and a portion of the filter cartridges 210 in the inlet section and the filter cartridge 220 in the storage section are exposed above the water surface. The exposed portions are equipped with the filter cartridge flushing assembly 600 in the inlet section and the filter cartridge flushing assembly 400 in the storage section to flush the filter screen. The flushing direction is opposite to the direction of the filtered water flow, which can prevent the filter screen from being blocked. Furthermore, due to the setting of the float plate 130, the entire filter can adjust its depth position in the water source according to the change of liquid level, so that the filtration device is always kept above the water surface.
