Description

Technical Field

[0001] This utility model relates to the field of farmland water conservancy technology, specifically to a pumping device for a farmland irrigation pumping station. Background Technology

[0002] Farmland irrigation refers to a series of water conservancy engineering measures taken to regulate farmland moisture conditions, prevent droughts and floods, and promote stable and high agricultural yields. Farmland irrigation pumping stations are important facilities used to pump water from water sources (such as rivers, lakes, and reservoirs) and transport it to farmland for irrigation. Their main function is to provide a stable source of irrigation water for farmland, meeting the water requirements for crop growth. Farmland irrigation pumping stations play a vital role in agricultural production, not only improving irrigation efficiency but also ensuring the stable operation of the equipment through various technical means.

[0003] Water used for farmland irrigation is usually drawn from surrounding rivers or reservoirs. Because this area is exposed to the outdoors for a long time, there are many impurities in the water. These impurities usually accumulate in the lower part of the water, while there are relatively few impurities on the surface.

[0004] When pumping equipment pumps water in rivers or reservoirs, in order to avoid the pipeline being blocked by impurities at the bottom of the water, the pipeline is usually installed at a depth close to the water surface. However, the water level of the reservoir or water flow is affected by the upstream water flow and the downstream water use, which causes the water level to change frequently. This affects the pumping of water through the pipeline. In addition, when the water level changes, the water flows and the thrust of the water flow can also cause the pipeline to move, affecting the stability of the pumping.

[0005] Therefore, we propose a pumping device for farmland irrigation pumping stations to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a pumping device for farmland irrigation pumping stations to solve the problems mentioned in the background art, such as the impact of water level changes in rivers or reservoirs on the pumping effect of the pumping pipe, and the impact of water level changes on the stability of the pumping pipe caused by water flow.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pumping device for a farmland irrigation pumping station, comprising a pump body, a water delivery pipe at one end of the pump body, and an auxiliary component for assisting in pumping at the other end of the water delivery pipe. The auxiliary component includes a mesh disposed at the other end of the water delivery pipe, an inner frame disposed inside the mesh, two electromagnets disposed on the outer wall of the inner frame, a slider disposed outside the mesh, a positioning groove disposed inside the slider, a spring and a push rod disposed inside the positioning groove, and a magnetic block disposed at one end of the push rod.

[0008] A column is provided on one side of the partition net, and a support rod is provided at one end of the column. The column has a sliding groove and a through groove inside, and a hollow plate is provided inside the through groove. An activation button is provided on one side of the hollow plate.

[0009] Preferably, the pump body input end is connected to the water delivery pipe through a sleeve, and the other output end is connected to the irrigation pipeline through a connecting pipe. The other end of the water delivery pipe is connected to the partition net through bolts, and both the partition net and the inner frame are hollow structures, with the water delivery pipe communicating with the interior of the partition net.

[0010] Preferably, the inner frame is located inside the partition mesh and is rotatably connected to the inner wall of the partition mesh via bearings and electrical control, and the two electromagnets are distributed in a ring on both sides of the outer wall of the inner frame.

[0011] Preferably, the slider is connected to the outer wall of the partition by bolts, the positioning groove passes through the end of the slider away from the partition, the top rod is located in the positioning groove and is slidably connected to the inner wall of the positioning groove, the two ends of the spring are respectively connected to the inner wall of the positioning groove and the top rod, the magnetic block is embedded and connected to the end of the top rod near the partition and is magnetically connected to the electromagnet outside the inner frame.

[0012] Preferably, the support rod has a tapered structure and is connected to the bottom of the column by bolts. The other end of the slider extends into a groove on one side of the column and is slidably connected to the inner wall of the groove by an electrically controlled slide rail.

[0013] Preferably, the through groove is connected to the slide groove, the hollow plate has a hollow structure inside and is equipped with a liquid level ball, and the hollow plate is located in the through groove and is slidably connected to the inner wall of the through groove. The activation button is electrically connected to the electrically controlled slide rail on the inner wall of the slide groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By installing a column on one side of the partition net at one end of the water pipe and embedding the column into the bottom of the water, the position of the water pipe can be locked. The column can also be used to pre-position the height of the water pipe during installation, thereby improving the stability of the pipeline in the water.

[0016] 2. Simultaneously, a hollow plate is installed inside the column. The liquid level ball inside the hollow plate can slide and rise / fall within the column according to water level changes. During the pumping process, the inner frame inside the screen continuously rotates within the screen. While improving the filtration effect, the electromagnet on the outer wall of the inner frame, when rotating past the slider, pushes the top rod inside the slider to one side through magnetic repulsion, pressing the activation button on one side of the hollow plate inside the column and sending a signal to the control center. When the water level changes and the hollow plate moves away from the slider area, the control center controls the slider to move within the column, thereby ensuring that the screen and pumping pipe are always aligned with the hollow plate. This ensures that the pumping pipe maintains optimal pumping performance at different water levels. Through this design, water level changes can be monitored and the pumping pipe position can be automatically adjusted, achieving efficient pumping.

[0017] This invention uses a column to fix the position of the pumping pipe, improving the stability of the pumping process. At the same time, it uses a level ball to automatically adjust the position of the hollow plate according to the water level change, ensuring that the pumping pipe is always at the optimal pumping point, improving pumping efficiency, reducing energy consumption, and extending the service life of the equipment.

[0023] 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.

[0024] Example 1: Please refer to Figures 1-4A pumping device for an agricultural irrigation pumping station includes a pump body 1. One end of the pump body 1 is provided with a water delivery pipe 2, extending into the water to facilitate pumping operations. The other end of the water delivery pipe 2 is provided with an auxiliary component for assisting pumping. The auxiliary component includes a mesh 3 located at the other end of the water delivery pipe 2. An inner frame 4 is provided inside the mesh 3. Both the mesh 3 and the inner frame 4 are used to filter impurities in the water during pumping, ensuring effective pumping. The inner frame 4 is electrically controlled to rotate within the mesh 3 during pumping, improving filtration through double-layer filtration and rotation. Two electromagnets 401 are provided on the outer wall of the inner frame 4. When energized, the electromagnets 401 generate magnetic poles and push against a rod within a slider 5. The magnetic blocks 601 at one end of the 6 repel each other, so when the electromagnet 401 of the inner frame 4 rotates to the area of ​​the slider 5, the electromagnet 401 and the magnetic block 601 repel each other, thereby pushing the top rod 6 to slide in the slider 5, so that one end of the top rod 6 extends out of the slider 5. The partition 3 is provided with a slider 5, which extends into the groove 702 on one side of the column 7, so that the partition 3 and the column 7 can slide, so that the height of the water pipe can be adjusted according to the sliding of the column 7. The slider 5 is provided with a positioning groove 501, which is used to position the angle of the top rod 6 when it slides. The positioning groove 501 is provided with a spring 502 and the top rod 6. The spring 502 is used to support the top rod 6 and push it to return to its original position. The top rod 6 is provided with a magnetic block 601 at one end.

[0025] A column 7 is provided on one side of the partition net 3. A support rod 701 is provided at one end of the column 7. One end of the column 7 extends into the bottom of the water and is embedded in the silt at the bottom of the water by the support rod 701, thereby supporting and fixing the angle of the column 7. The column 7 is used to help position the water pump pipe. The inside of the column 7 is provided with a sliding groove 702 and a through groove 703. The through groove 703 communicates with the sliding groove 702, so that the top rod 6 extending from one end of the slider 5 can be inserted into the through groove 703. A hollow plate 8 is provided inside the through groove 703. When the liquid level ball inside plate 8 is in water, it can be kept at a height close to the water surface by buoyancy. An activation button 9 is provided on one side of the hollow plate 8. When the activation button 9 is triggered, it sends a signal to the control center to remind the control center. If the activation button 9 is not triggered for a long time during the water pumping process and the control center does not receive a signal, it means that the position of the water pumping pipe is far away from the hollow plate 8 area. The control slider 5 will be operated to slide inside the column 7 to adjust the height of the partition net 3 and the water pumping pipe to the hollow plate 8 area to ensure water pumping efficiency.

[0026] In this embodiment: the column 7 is installed in the water, and the slider 5 positions the mesh 3 and the pumping pipe, keeping them in the water and close to the water surface. During pumping, the inner frame 4 rotates within the mesh 3. When the electromagnet 401 rotates to the area of ​​the slider 5, the magnetic block 601 is repulsed, causing the push rod 6 to slide out from one end of the slider 5 and extend through the groove 702 of the column 7 into the through groove 703. At the same time, it is triggered by pressing the activation button 9 on one side of the hollow plate 8 in the through groove 703, and a signal is sent to the control center to ensure the accurate positioning of the pumping pipe. If the signal is interrupted, the control center immediately adjusts the slider 5 to realign the mesh 3 and the pumping pipe with the hollow plate 8 area, maintaining efficient pumping. The electromagnet 401 continues to rotate, and the push rod 6 is reset under the action of the spring 502, repeating the process. After pumping out the water source, the pump body 1 delivers the water to the irrigation pipeline through the connecting pipe to irrigate the farmland.

[0027] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 1-4 The pump body 1 has an input end connected to the water delivery pipe 2 via a sleeve, and an output end connected to the irrigation pipeline via a connecting pipe. The other end of the water delivery pipe 2 is connected to the partition 3 via bolts. Both the partition 3 and the inner frame 4 are hollow structures, and the water delivery pipe 2 and the partition 3 are internally connected. The inner frame 4 is located inside the partition 3 and is rotatably connected to the inner wall of the partition 3 via bearings and electrical control. Two electromagnets 401 are distributed in a ring on both sides of the outer wall of the inner frame 4. The slider 5 is connected to the outer wall of the partition 3 via bolts. The positioning groove 501 passes through the end of the slider 5 away from the partition 3. The top rod 6 is located inside the positioning groove 501 and is slidably connected to the inner wall of the positioning groove 501. The spring 502 has two ends... The magnetic block 601 is embedded and connected to the inner wall of the positioning groove 501 and the top rod 6. It is also magnetically connected to the electromagnet 401 outside the inner frame 4. The support rod 701 is a tapered structure and is connected to the bottom of the column 7 by bolts. The other end of the slider 5 extends into the slide groove 702 on one side of the column 7 and is slidably connected to the inner wall of the slide groove 702 by an electrically controlled slide rail. The through groove 703 is connected to the slide groove 702. The hollow plate 8 has a hollow structure inside and is equipped with a liquid level ball. The hollow plate 8 is located in the through groove 703 and is slidably connected to the inner wall of the through groove 703. The activation button 9 is electrically connected to the electrically controlled slide rail on the inner wall of the slide groove 702.

[0028] In this embodiment, the column 7 can be embedded into the bottom of the water via the support rod 701 at the bottom, thereby fixing the water pump pipe and preventing interference with the position of the water pump pipe when the water is flowing. This maintains the pumping effect, and the height of the column 7 can be customized according to the actual usage scenario.

[0029] Working Principle: During operation, the column 7 is first embedded into the water to ensure stability. Then, the slider 5 slides within the column 7, causing the mesh screen 3 and the pumping pipe to extend into the designated position in the water, precisely aligning with the hollow plate 8 area. During pumping, the inner frame 4 and mesh screen 3 rotate to assist in filtering impurities. When the electromagnet 401 outside the inner frame 4 rotates to the slider 5 area, it repels the magnetic block 601 at one end of the push rod 6, causing the push rod 6 to move out of the slider 5 and extend into the through groove 703 of the column 7. Pressing the activation button 9 on one side of the hollow plate 8 activates the system, sending a signal to the control center. When the hollow plate 8 moves away from the mesh screen 3 area due to water level changes, the control center loses the signal and controls the slider 5 to slide within the column 7, adjusting the height of the mesh screen 3 and the pumping pipe to align with the hollow plate 8 area, maintaining the pumping effect. This design not only improves the stability and efficiency of the pumping system.
