Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to an irrigation water pump with a filter structure. Background Technology

[0002] In the process of agricultural production, water pumps are needed to irrigate farmland regularly and in fixed quantities. Water pumps are machines that transport or pressurize liquids and are widely used in farmland irrigation, industrial drainage, and other fields.

[0003] A search revealed, for example, a utility model with publication number CN219081937U, which discloses a water pump for agricultural irrigation. The pump includes a main body. By pushing a ring frame, an elastic locking block engages with the inside of a fiber groove, creating a limiting position. When debris enters, it is filtered through a filter plate and then continuously slides outwards under the impact of subsequent water flow. However, this utility model requires the pump to be shut down for maintenance and cleaning of the filter structure, which increases the irrigation time and reduces irrigation efficiency. Therefore, to address these shortcomings, the inventor proposes an irrigation water pump with a filter structure. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a water pump for agricultural irrigation, which effectively reduces the impact of maintenance and cleaning of filter plates on irrigation efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An irrigation pump with a filtration structure includes a pump, an inlet flange of which is connected to an installation pipe, a first tee is fixedly installed at the end of the installation pipe away from the pump, and water delivery pipes are fixedly installed at both inlets of the first tee. A connecting pipe is provided on one side of the pump, and a second tee is fixedly installed at one end of the connecting pipe. Fixed pipes are fixedly installed at both outlets of the second tee. Two filter cylinders are flangedly connected to the opposite ends of the two fixed pipes and the two water delivery pipes. Filter plates are provided inside the two filter cylinders. A fixing box is fixedly installed on one side of the outer surface of the two water supply pipes and one side of the outer surface of the two fixed pipes, and a switching component is provided between the first tee and the second tee.

[0006] Preferably, the switching assembly includes two movable arms that are rotatably connected to the outer surfaces of the first tee and the second tee respectively, and a switching block is fixedly installed between the two movable arms. Both ends of the switching block are provided with fixing grooves, and rubber pads are fixedly installed inside the two fixing grooves.

[0007] Preferably, a baffle is slidably connected inside the fixing box, and a fixing block matching the fixing groove is fixedly installed on one side of the outer surface of the fixing box. A dustproof cloth cover is fixedly connected between the fixing block and the outer surface of the fixing box.

[0008] Preferably, a movable hole is provided on one side of the outer surface of the fixed box, and a sealing ring is fixedly installed on the inner wall of the movable hole. A movable rod is fixedly installed on one side of the baffle, and one end of the movable rod extends through the movable hole to the outside of the fixed box and is fixedly connected to the fixed block.

[0009] Preferably, a spring is fixedly connected between one side of the outer surface of the fixing box and the fixing block, and the spring is sleeved on the outer end of the movable rod, and the dustproof cloth sleeve is sleeved on the outer end of the spring.

[0010] Preferably, a retaining ring is fixedly installed on the inner wall of the filter cylinder, a plurality of mounting holes are opened on the outer surface of the filter cylinder, and a plurality of connection holes corresponding one-to-one with the mounting holes are opened on the side of the filter plate.

[0011] Compared with existing technologies, this utility model has the following advantages: This utility model discloses an irrigation pump with a filtration structure. By setting up an installation pipe and manually flipping the switching block, the switching block is inserted between two fixed blocks until the fixed blocks are inserted into the fixed groove. This allows the movable rod and baffle to move, blocking the corresponding internal channels of the fixed boxes. The other two fixed blocks, lacking the obstruction of the switching block, will move closer together under the elastic action of the spring, opening the internal channels of the other two fixed boxes. Water can then enter another water supply pipe and the fixed pipe, thus switching the water flow direction. This allows switching the water flow channel without interrupting irrigation, significantly improving the system's continuous operation capability, especially suitable for water sources with high impurity content. Furthermore, the three-way structure allows for the subsequent expansion of more filtration channels, improving the system's scalability. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model discloses an irrigation pump with a filtration structure, such as Figure 1-5 As shown, the pump includes a pump 1. The motor of the pump 1 drives the pump shaft to rotate at high speed, and the impeller rotates synchronously with the shaft. At this time, the water in the impeller is driven to rotate together by the blades and is thrown out towards the edge of the impeller by centrifugal force.

[0017] The high-speed water flow thrown out by the impeller enters the volute channel of the pump casing. As the cross-sectional area of ​​the channel gradually expands, the water flow velocity gradually decreases, and the kinetic energy is converted into pressure energy. Finally, the water is discharged from the outlet of the pump casing and transported to the field through pipelines to complete the irrigation.

[0018] Since different usage scenarios require different types of water pumps, they will not be specified here.

[0019] In order to filter impurities in the water, an installation pipe 2 is connected to the inlet flange of the water pump 1. A first tee 201 is fixedly installed at the end of the installation pipe 2 away from the water pump 1, and water supply pipes 203 are fixedly installed at both inlets of the first tee 201. Through the first tee 201, water can flow into the installation pipe 2 through either of the two water supply pipes 203, and then into the interior of the water pump 1.

[0020] A connecting pipe 204 is provided on one side of the water pump 1. The connecting pipe 204 is connected to an external pipe, and a second tee 205 is fixedly installed at one end of the connecting pipe 204. Fixed pipes 206 are fixedly installed at both outlets of the second tee 205. Two filter cylinders 207 are flanged at the opposite ends of the two fixed pipes 206 and the two water supply pipes 203. Filter plates 2073 are provided inside the two filter cylinders 207.

[0021] Through the second three-way valve 205, external water flow can enter the interior of the connecting pipe 204 and then enter the corresponding filter cylinder 207 through any fixed pipe 206, and subsequently enter the corresponding water supply pipe 203. The stainless steel filter plate 2073 inside the filter cylinder 207 can filter impurities inside the water flow.

[0022] In order to switch the direction of water flow, a fixing box 202 is fixedly installed on one side of the outer surface of the two water supply pipes 203 and one side of the outer surface of the two fixed pipes 206. A switching component is provided between the first tee 201 and the second tee 205.

[0023] The switching assembly includes two movable arms 208 that are rotatably connected to the outer surfaces of the first tee 201 and the second tee 205, respectively. Rotating rods are provided on the outer surfaces of the first tee 201 and the second tee 205. A sleeve is provided at one end of each movable arm 208. The sleeves of the two movable arms 208 are respectively fitted onto the outer ends of the two rotating rods and connected to the two rotating rods, so that the movable arms 208 can rotate around the rotating rods. A switching block 209 is fixedly installed between the two movable arms 208. Through the two movable arms 208, the operator can manually flip the switching block 209. Fixed grooves 210 are provided at both ends of the switching block 209. Rubber pads 211 are fixedly installed inside the two fixed grooves 210.

[0024] A baffle 2021 is slidably connected inside the fixed box 202. The baffle 2021 can slide inside the fixed box 202, thereby blocking or opening the water supply channel inside the fixed box 202.

[0025] A fixing block 2023 matching the fixing groove 210 is fixedly installed on one side of the outer surface of the fixing box 202, and a dustproof cloth cover 2025 is fixedly connected between the fixing block 2023 and the outer surface of the fixing box 202.

[0026] A movable hole 2026 is provided on one side of the outer surface of the fixed box 202, and a sealing ring 2027 is fixedly installed on the inner wall of the movable hole 2026. A movable rod 2022 is fixedly installed on one side of the baffle 2021, and one end of the movable rod 2022 extends through the movable hole 2026 to the outside of the fixed box 202 and is fixedly connected to the fixed block 2023. When the fixed block 2023 moves, it will drive the movable rod 2022 and the baffle 2021 to move. The sealing ring 2027 can effectively improve the sealing between the inner wall of the movable hole 2026 and the outer surface of the movable rod 2022, effectively preventing water entering the fixed box 202 from flowing out through the gap between the movable hole 2026 and the movable rod 2022.

[0027] A spring 2024 is fixedly connected between one side of the outer surface of the fixed box 202 and the fixed block 2023. The spring 2024 is sleeved on the outer end of the movable rod 2022, and the dust cover 2025 is sleeved on the outer end of the spring 2024. The dust cover 2025 can effectively reduce the probability of external dust and impurities entering the gap of the spring 2024 without affecting the normal deformation of the spring 2024.

[0028] The operator manually flips the switching block 209, inserting it between two fixed blocks 2023. During insertion, the fixed blocks 2023 are gradually moved, compressing the spring 2024. This, in turn, moves the movable rod 2022 and the baffle 2021. Once the switching block 209 is inserted between the two fixed blocks 2023, the two fixed blocks 2023 are inserted into the two fixed slots 210. At this point, the baffle 2021 blocks the water supply channel of the fixed box 202, preventing water from entering the fixed box 202. The design of the spring 2024 and the sealing ring 2027 ensures the sealing of the baffle 2021 when it resets, preventing water leakage from non-working channels and reducing energy loss.

[0029] Furthermore, by manually flipping the switching block 209, the four fixed boxes 202, which are grouped in pairs, can be opened or closed. When the filter plate 2073 is clogged, it will block the flow of water, thus reducing the irrigation output. When using irrigation, the operator can judge the degree of clogging of the filter plate 2073 based on the water output. When it is necessary to maintain or clean one of the filter plates 2073, the corresponding two fixed boxes 202 can be closed by flipping the switching block 209, and the water will then flow into another water pipe 203 and fixed pipe 206, thereby switching the direction of water flow.

[0030] To facilitate the assembly and disassembly of the filter plate 2073, a retaining ring 2072 is fixedly installed on the inner wall of the filter cylinder 207. Multiple mounting holes 2071 are provided on the outer surface of the filter cylinder 207, and multiple connecting holes 2074 corresponding to the mounting holes 2071 are provided on the side of the filter plate 2073. The filter plate 2073 is inserted into the filter cylinder 207 until it contacts the retaining ring 2072. A sealing gasket can also be placed between the filter plate 2073 and the retaining ring 2072. Then, the filter plate 2073 is rotated until the mounting holes 2071 and the connecting holes 2074 coincide. Afterward, a bolt is inserted to complete the installation of the filter plate 2073. For disassembly, simply pull out the bolts inserted into the coincident mounting holes 2071 and connecting holes 2074 to remove the filter plate 2073.
