Description

Technical Field

[0001] The invention relates to the technical field of deep well pumps, in particular to a self-cleaning and anti-blocking deep well pump. Background Art

[0002] Farmland irrigation is an indispensable part of agricultural production. It is particularly critical in areas of drought or water scarcity. Traditional irrigation methods often rely on surface water sources, such as rivers and lakes, but these water sources are often affected by multiple factors such as season and climate, resulting in unstable irrigation water sources.

[0003] A deep well pump is a device that integrates an electric motor and a water pump. It is widely used in farmland irrigation. The pump body of the deep well pump is placed in a deep well and completely immersed in the well water. Then the engine is started, so that the engine output shaft drives multiple sets of impellers, and the well water is pumped out of the well by the centrifugal force of the impeller rotation. However, the water source in the deep well contains impurities such as silt, rock particles, and welding slag. These impurities directly enter the pump body and cause wear and blockage to the impeller, bearings and other components in the pump body, affecting the normal operation of the pump body. The existing deep well pump is provided with a water filter pipe at its water inlet, which is used to filter impurities in the water entering the pump body, thereby preventing impurities in the water from directly entering the pump body. However, in order to meet the actual irrigation demand of farmland, deep well pumps usually need to operate for a long time. During the use of the water filter pipe provided on the deep well pump, impurities in the water entering the pump body are filtered out by the filter pipe, causing the impurities filtered out from the water entering the pump body to gradually accumulate on the surface of the filter pipe due to the fluidity of the water. The impurities accumulated on the filter pipe will gradually block the filter holes on the filter pipe, thereby causing poor water flow and affecting the pumping efficiency of the deep well pump.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the water inlet pipe 1 and the water inlet pipe 2, the filter plate is displaced by the pressure difference, so that the channel for water to enter the pump body is switched from the water inlet pipe 1 to the water inlet pipe 2, and the guide rod is used to push the driving cylinder to close the multiple opening and closing plates. The impurities on the filter plate are not affected by the pressure difference and fall off the filter plate, and reset under the elastic force of the spring 2, so that the water body enters the pump body through the water inlet pipe 1 again, avoiding the blockage of the filter plate caused by excessive accumulation of impurities on the filter plate, ensuring that the water body can smoothly enter the pump body, and improving the pumping efficiency of the pump body; 2. The baffle is limited by the closing plate, so that during the resetting process of the filter plate, the rotating column slides along the rotating groove, causing the moving rod to drive the scraper bar to rotate along the surface of the filter plate, thereby scraping off the impurities agglomerated on the surface of the filter plate, improving the cleaning effect of the impurities on the surface of the filter plate, and collecting the impurities cleaned by the filter plate through the collecting groove, and finally the impurities are thrown out of the collecting groove under the action of centrifugal force, so that the impurities are thrown to a position relatively far away from the opening end of the water inlet pipe, further improving the cleaning effect of the impurities on the filter plate, and avoiding the impurities from clogging the filter plate again; 3. By moving the filter plate and driving the control strip, the filter plate is shifted to a position where multiple closing plates are closed. At this time, the clamping rod drives the control plate and the drainage plate to shift, so that the water in the drainage cavity is discharged through the guide port, so that the flow of the water discharged from the drainage cavity guides the impurities detached from the filter plate, so that the impurities are further away from the water inlet pipe 1, thereby avoiding the impurities from clogging the filter plate 1 and improving the pumping efficiency of the pump body.

[0036] When the deep well pump is working, the suction force generated by the rotation of the impeller will form a certain pressure difference in the water inlet pipe. The pressure at the water inlet end is relatively high, while the pressure at the end close to the pump body 1 is lower. When the sediment gradually accumulates on the filter plate 21 but does not completely block the filter plate, the water flow can still flow through the pores on the filter plate 21. Then the pressure difference will cause the filter plate to generate a force in the direction of the pump body 1, causing the filter plate to slide along the water inlet pipe.

[0037] During use, in the initial state, under the elastic force of the second spring, the filter plate 21 is located at the open end of the water inlet pipe 13 away from the circulation pipe 12, and the filter cartridge 24 shrinks into the water inlet pipe 14. At this time, the water can only pass through the filter plate 21 and enter the circulation pipe 12 from the water inlet pipe 13. First, the pump body 1 is completely immersed in the well water of the deep well. At this time, the water in the deep well naturally penetrates into the circulation pipe 12 from the water inlet pipe 13 through the filter plate 21, and then the motor is started, so that the output shaft of the motor drives the transmission shaft, causing the multiple impellers on the transmission shaft to rotate synchronously with the transmission shaft. At this time, the water entering the upper shell from the circulation pipe 12 will be affected by the centrifugal force of the impeller when it rotates and move toward the water outlet and spray out from the water outlet; At this time, the pressure in the pump body 1 decreases, forming a negative pressure area. Under the action of atmospheric pressure, the water outside the pump body 1 will pass through the filter hole 1 on the filter plate 21 and enter the water inlet pipe 13, then enter the flow pipe 12, and finally spray out from the water outlet; When the water outside the pump body 1 enters the water inlet pipe 13, the impurities in the water will be filtered out by the filter hole 1 on the filter plate 21. As the filter plate 21 filters for a long time, impurities will gradually accumulate on the side of the filter plate 21 away from the water inlet pipe 13. When the impurities accumulated on the filter plate 21 block some of the filter holes, the filter plate 21 is pushed by the pressure difference. The filter plate 21 slides along the keyway toward the direction of the water inlet pipe 2 14 through the slider 25, and the spring 2 is deformed. At this time, the filter plate 21 will push the filter cartridge 24 through the moving rod 22, the connecting rod 1 23, the connecting frame 232, and the connecting rod 2 233, so that the filter cartridge 24 is pushed out of the water inlet pipe 2 14. At this time, the water outside the pump body 1 can enter the water inlet pipe 2 14 through the multiple filter holes 2 on the filter cartridge 24, and enter the circulation pipe 12 from the water inlet pipe 2 14, and finally be discharged from the water outlet; At the same time, the slide plate 1 251 and the slide plate 252 will move synchronously with the filter plate 21, and the guide rod 2521 will slide along the driving groove 271 on the driving cylinder 27, so that the driving cylinder 27 rotates under the push of the guide rod 2521. At this time, the rotating ring 284 rotates. Initially, the multiple opening and closing plates avoid each other. When the pull rod 285 is pulled by the rotating ring 284 to pull the closing plate 282, the multiple closing plates 282 approach each other, and then the water inlet hole is blocked. At this time, the baffle 231 is located on the side of the closing plate 282 close to the flow pipe 12; At the same time, the rotation of the driving cylinder 27 causes the moving plate 291 to gradually move away from the fixed plate 29, causing the spring three to deform. When the moving plate 291 moves to contact the chamfered structure of the locking rod 292, the spring four deforms, and the locking rod 292 contracts into the elastic groove three. When the moving plate 291 continues to shift to be separated from the locking rod 292, the spring four resets, and the locking rod 292 extends out of the elastic groove three and limits the moving rod 22. At this time, the locking tongue 293 slides into the movable groove. Since the closing plate 282 blocks the water inlet hole, the water will not enter the water inlet pipe 13 and flow into the flow pipe 12 from the filter plate 21, so that the filter plate 21 is reset by the reset elastic force of the spring 2. Since the filter plate 21 area is not subjected to the force of the pressure difference at this time, the impurities attached to the filter plate 21 will gradually fall off and settle naturally. At the same time, when the filter plate 21 is reset, the guide rod 2521 will gradually move away from the driving cylinder 27. When the filter plate 21 is reset to contact with the lock tongue 293, the filter plate 21 will drive the lock tongue 293 to move synchronously, causing the lock rod 292 to shrink into the elastic groove 3, and the spring 4 is deformed. When the lock rod 292 is separated from the moving plate 291, the moving plate 291 will be reset under the reset elastic force of the spring 3, and the driving cylinder 27 is reset. Because the multiple closing plates 282 limit the baffle 231, the connecting rod 23 cannot be reset. At this time, the spring 1 is deformed, and the filter cartridge 24 is still in a state of extending out from the water inlet pipe 2 14. The water outside the pump body 1 enters the circulation pipe 12 only through the water inlet pipe 2 14. When the driving cylinder 27 is reset, the multiple closing plates 282 move away from each other. At this time, the filter cartridge 24, the connecting rod 1 23, the connecting rod 233, and the connecting frame 232 will move toward the filter plate 21 under the action of the reset elastic force of the spring 1. At this time, the water will no longer enter the circulation pipe 12 through the filter cartridge 24, but instead enter the circulation pipe 12 from the water inlet pipe 13 through the filter plate 21.

The rotating block 31 is connected to the end of the moving rod 22 close to the connecting rod 23, and the rotating block 31 is slidably arranged in the plug-in groove, the rotating groove 33 is arranged on the inner wall of the plug-in groove, a ball is arranged at the end of the rotating column 32 away from the rotating block 31, and the rotating column 32 is slidably arranged in the rotating groove 33, and the ball is used to reduce the friction resistance between the rotating column 32 and the rotating groove 33, the scraper 34 is arranged at the end of the moving rod 22 close to the filter plate 21, and the scraper 34 is attached to the surface of the filter plate 21 away from the circulation tube 12, and a plurality of scrapers 34 are arranged in an array on the moving rod 22.

[0040] When the filter plate 21 is in use, the filter plate 21 is reset and the closing plate 282 limits the baffle 231, the rotating block 31 follows the moving rod 22 to slide along the plug-in slot, so that the rotating block 31 slides along the rotating slot 33 during the displacement process. At this time, the moving rod 22 will rotate, and the moving rod 22 drives multiple scraping bars 34 to sweep and scrape the surface of the filter plate 21, so that the agglomerated impurities attached to the surface of the filter plate 21 are scraped off, and some of the agglomerated impurities scraped off from the surface of the filter plate 21 will be collected by the collecting groove 35. The agglomerated impurities entering the collecting groove 35 are accumulated at the end of the scraping bar 34 away from the moving rod 22 under the action of centrifugal force during the rotation of the scraping bar 34. When the filter plate 21 is reset to the initial position, the scraping bar 34 extends to the outside of the water inlet pipe 13, and the agglomerated impurities in the collecting groove 35 will be thrown out of the collecting groove 35.
