Description

Technical Field

[0001] This invention relates to water pump technology, specifically an anti-clogging water pump for farmland irrigation. Background Technology

[0002] A water pump is a small instrument that has one inlet and one outlet nozzle, and can continuously create a vacuum or negative pressure at the inlet and a slight positive pressure at the outlet. The working medium can be gas or liquid.

[0003] In existing technologies, when a water pump is used for irrigation, the water drawn in through the inlet pipe contains many impurities. These impurities accumulate inside the pump and can hinder the normal operation of the internal equipment. Furthermore, during the filtration process, the filter screen is easily clogged, preventing water flow and negatively impacting the pump's pumping efficiency. During prolonged operation, the internal equipment generates significant heat, raising the pump's internal temperature and potentially shortening its lifespan.

[0004] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of this invention is to enhance the crushing ability of the pulverizing blades in the water flow, and to discharge the impurities filtered by the filter screen frame into the filter box by the push of the scraper gate, so that the filtration effect of the filter screen frame will not weaken as the amount of impurities increases. The cross-shaped rotating block on the rotating rod lifts the movable plate in the connecting frame, thereby lifting the filter screen frame, which facilitates the removal of impurities from the filter screen frame by the scraper gate. During the rotation of the rotating rod, the reciprocating plate is driven to stretch and compress the telescopic hose, so that the telescopic hose flows the water inside the filter box to the water delivery pipe to cool the inside of the water pump.

A filter screen frame is slidably connected to the inner sidewall of the filter hole corresponding to the position of the movable groove.

[0011] In a preferred embodiment of the present invention, a reciprocating groove is provided on the outer side wall of the rotating rod near the transmission wheel, a reciprocating plate is slidably connected to the outer side wall of the rotating rod corresponding to the position of the reciprocating groove, a telescopic hose is connected to the outer side wall of the reciprocating plate near the lower part of the rotating rod, a limit plate is connected to the lower surface of the filter box corresponding to the position of the reciprocating plate, and a support plate is connected to the outer side wall of the rotating rod corresponding to the side of the reciprocating plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The planetary gear structure inside the rotating shaft enables the coaxial reverse rotation of the crushing blades, which has a stronger ability to crush impurities in the water flow. The flexible impurities can be crushed by the tearing force of the reverse rotation. The reciprocating screw drives the scraper gate to reciprocate on the filter plate. Under the detection of two touch sensors, the scraper gate is closed when scraping and opened when moving back. The impurities filtered by the filter frame can be discharged into the filter box by the push of the scraper gate. The filtration effect of the filter frame on impurities will not be weakened by the increase of impurities, and the impurities will not flow to the pump body and affect the normal operation of the pump body.

[0015] 2. When the filtered water flows towards the inlet pipe, it drives the rotating rod to rotate, causing several cross-shaped rotating blocks connected to the rotating rod to lift the movable plate inside the connecting frame. This causes the movable plate to lift the filter screen frame inside the filter holes on the filter plate, making it easier for the scraper gate to remove impurities from the filter screen frame and reducing the impact of impurities on the filter screen frame and the water flow filtration speed.

[0016] 3. During the rotation of the rotating rod, the reciprocating plate is driven to stretch and compress the telescopic hose, so that the telescopic hose flows the water inside the filter box to the water supply pipe to cool the inside of the water pump. When the temperature inside the water pump is too high, a semiconductor cooling chip is used for cooling. Attached Figure Description

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1-3 and Figure 6As shown, an anti-clogging water pump for farmland irrigation includes a pump body 1, an outlet pipe 2, and a suction pipe 3. The suction pipe 3 is connected to one side of the outer wall of the pump body 1, and the outlet pipe 2 is connected to the upper surface of the pump body 1. A filter box 42 is connected to the end of the suction pipe 3 away from the pump body 1. An electrical control box is connected to the outer wall of the filter box 42, which contains data processing equipment and a timer. Touch sensors, one and two, are installed on both sides of the upper surface of the filter box 42. A discharge gate 41 is connected to the side of the outer wall of the filter box 42 near the suction pipe 3, and an inlet pipe 43 is connected to the side of the outer wall of the filter box 42 away from the suction pipe 3. A filter plate 46 is integrally formed in the middle of the inner wall of the filter box 42. Plate 46 and partition plate 47 divide the internal space of filter box 42 into upper and lower layers. Partition plate 47 is integrally formed on one side of the upper surface of filter plate 46. Scraper gate 45 is slidably connected to the upper surface of filter plate 46. The length and width of scraper gate 45 are the same as the length and width of the upper space of the separated filter box 42. Gate plate 416 is slidably connected to the lower side of the inner wall of scraper gate 45. Reciprocating screws 44 are rotatably connected to both sides of the outer wall of scraper gate 45. Rotating parts are connected to both sides of scraper gate 45 at positions corresponding to the reciprocating screws 44. The rotating parts cause scraper gate 45 to move outside the reciprocating screws 44 during rotation. Crushing blades 413 are rotatably connected to the upper surface of filter plate 46 at positions corresponding to partition plate 47. The upper and lower crushing blades 413 are connected by a planetary gear structure, allowing them to rotate coaxially and in reverse, thus improving their ability to crush impurities entering the filter box 42. A blade groove 48 is provided on the outer wall of the impurity-separating plate 47 at the position corresponding to the crushing blade 413. The blade groove 48 scrapes off impurities adhering to the crushing blade 413 when the blade 413 rotates to the position of the blade groove 48. A connecting rod 412 is integrally formed at one end of the reciprocating screw 44 near the crushing blade 413. The two connecting rods 412 are driven by a transmission wheel 49 connected at one end and a transmission belt 411 on the outer side of the transmission wheel 49. The transmission wheel 49 at one end of one connecting rod 412 is connected to the transmission wheel 411 on the rotating rod 510 via the transmission belt 411. 9. A transmission connection is established. Half-toothed rollers 410 are rotatably connected to the upper surface and outer wall of the filter plate 46 at positions corresponding to the crushing blade 413. One side of the outer wall of each half-toothed roller 410 has a gear structure. Two half-toothed rollers 410 are perpendicular to each other and interlock to rotate. The horizontal half-toothed rollers 410 are connected to the shaft of the crushing blade 413 via a transmission belt 411. The half-toothed rollers 410 are also connected to a transmission roller 49 via the transmission belt 411. The transmission roller 49 is connected to the transmission mechanism. A movable box 414 is connected to the outer wall of the scraper gate 45 away from the crushing blade 413. An extrusion block 415 is slidably connected inside the movable box 414. A sealing gasket is connected to the outer wall of the movable box 414 at the position corresponding to the extrusion block 415.Inside the movable box 414, the compression block 415 has return springs connected to both sides. One end of the return spring is connected to the compression block 415, and the other end is connected to the inner wall of the movable box 414. A pressure sensor is connected inside the movable box 414 at the position between the two return springs.

[0030] In the prior art, when the water pump body 1 is used for irrigation of farmland after drawing water, there are many impurities in the water flow drawn through the water inlet pipe 43. After the impurities enter the water pump body 1 and accumulate together, they can easily hinder the normal operation of the internal equipment of the water pump body 1.

[0031] As the filtered water flows from the inlet pipe 43 to the pump body 1, it drives the propeller blade 58 to rotate. This causes the rotating rod 510 connected to the propeller blade 58 to rotate via the transmission wheel 49 and the transmission belt 411. The reciprocating screw 44, which is integrated with the connecting rod 412, rotates during this process, causing the scraper gate 45 to move on the surface of the filter plate 46. The transmission wheel 49 on the rotating rod 510 is connected to the vertical half-tooth wheel 410 via the transmission belt 411. The vertical half-tooth wheel 410 and the horizontal half-tooth wheel 410 are interlocked. Wheel 410 is connected to the shaft of crushing blade 413 via transmission belt 411. The crushing blades 413 are connected to each other via planetary gear structure to achieve coaxial reversal. When the rotating rod 510 rotates, it drives the crushing blades 413 to crush impurities entering the water flow from the inlet pipe 43. The reverse-rotating crushing blades 413 crush the impurities more thoroughly. The crushed impurities flow with the water flow to the filter holes 53 on the filter plate 46. The water flows downward from the filter holes 53, and the impurities in the water flow are filtered down by the filter screen frame inside the filter holes 53. The impurities accumulated on the filter plate 46 are scraped by the scraper gate 4. 5. During the movement, the impurities are scraped away and pushed to one side of the space above the filter plate 46. The scraping gate 45 squeezes the accumulated impurities, reducing the space occupied by the impurities. During the squeezing process, the squeezing block 415 inside the movable box 414 is squeezed and squeezes the pressure sensor inside the movable box 414, causing the pressure sensor to transmit the detected pressure data to the data processing equipment inside the electrical control box. The data processing equipment compares the detected pressure data value with the preset pressure data value. When the comparison shows that the detected pressure data value is greater than the preset pressure data value, it controls the discharge gate 41 to open and discharge the impurities inside the filter box 42. The water flow is blocked by the scraper gate 45 and will not flow outward. The filter holes 53 on the filter plate 46 corresponding to the impurity positions are filled with squeezed and compacted impurities and will not leak water. After the scraper gate 45 moves to one end of the filter box 42, it touches the first touch sensor. The first touch sensor transmits a signal to the electrical control box to control the unloading gate 41 to close. After the unloading gate 41 closes, the gate plate 416 of the scraper gate 45 is opened. After the gate plate 416 opens, the scraper gate 45 moves to one end on the reciprocating screw 44 and moves in the opposite direction. After the reverse movement touches the second touch sensor, the gate plate 416 of the scraper gate 45 closes and the scraping operation is performed again.

[0032] Example 2:

[0033] Please see Figure 1-6As shown, the transmission mechanism includes a rotating rod 510. One end of the rotating rod 510, corresponding to the inner side of the connecting frame 57, is connected to a propeller blade 58. A connecting frame 51 is connected to the inner wall of the filter box 42 near the lower part of the filter plate 46. A bottom frame 56 is integrally formed on both sides of the lower surface of the connecting frame 51. A movable plate 55 is slidably connected inside the connecting frame 51. The movable plate 55 slides up and down inside the connecting frame 51 and is connected to the upper end of a telescopic spring 59. A telescopic spring 59 is connected to the upper surface of the bottom frame 56 at the position corresponding to the movable plate 55. The lower end of the telescopic spring 59 is connected to the bottom frame 56. A cross-shaped rotating block 52 is connected to the outer wall of the rotating rod 510 at the position corresponding to the movable plate 55. The protruding part of the cross-shaped rotating block 52 can push the movable plate 55 to move upward inside the connecting frame 51 during rotation. A filter hole 53 is opened on the upper surface of the filter plate 46 at the position corresponding to the movable plate 55. Movable grooves 54 are opened on both sides of the inner wall of the filter hole 53. A filter screen frame is slidably connected to the inner wall of the filter hole 53 at the position corresponding to the movable groove 54. The filter screen frame can slide up and down inside the filter hole 53. When it slides to the top, the upper surface of the filter screen frame is flush with the upper surface of the filter plate 46.

[0034] In the prior art, during the process of filtering impurities in the water flow, the filter screen holes on the filter screen frame are easily blocked by impurities. After being blocked, the filter screen cannot allow water to flow, which adversely affects the pumping efficiency of the water pump body 1.

[0035] As the filtered water flows from the inlet pipe 43 to the pump body 1, it drives the propeller blade 58 to rotate. The rotating rod 510 connected to the propeller blade 58 drives several evenly distributed cross rotating blocks 52 to rotate during rotation. The included angle between adjacent cross rotating blocks 52 is 45 degrees, so that when one of the two adjacent cross rotating blocks 52 lifts the movable plate 55, the other cross rotating block 52 will not lift the movable plate 55. The lifted movable plate 55 is inserted into the filter hole 53, reducing the space available for water flow. The staggered angle of the adjacent cross rotating blocks 52 ensures that when the cross rotating blocks 52 lift, adjacent positions will not be lifted, facilitating the continued flow of water. The lifted movable plate 55 lifts the filter screen frame inside the filter hole 53, so that the impurities accumulated on the filter screen frame can be scraped away by the scraper gate 45 to achieve a cleaning effect, so that the impurities do not affect the filtration effect of the filter screen frame on impurities in the water flow.

[0036] Example 3:

[0037] Please see Figure 7-8As shown, a reciprocating groove 68 is provided on the outer wall of the rotating rod 510 near the transmission wheel 49. A reciprocating plate 610 is slidably connected to the outer wall of the rotating rod 510 at the position corresponding to the reciprocating groove 68. The reciprocating plate 610 reciprocates within the area of ​​the reciprocating groove 68 during the rotation of the rotating rod 510, stretching and compressing the telescopic hose 62. The telescopic hose 62 is connected to the outer wall of the reciprocating plate 610 near the lower part of the rotating rod 510. A limit plate 69 is connected to the lower surface of the filter box 42 at the position corresponding to the reciprocating plate 610, limiting the range of motion of the reciprocating plate 610. A support plate is connected to the outer wall of the rotating rod 510 on the side corresponding to the reciprocating plate 610. Connecting pipes 67 are connected to both sides of the outer wall of the telescopic hose 62. One-way valves are connected to both ends of the telescopic hose 62. A water supply pipe 64 is integrally formed at the position of the connecting pipe 67 on one side of the outer wall of the flexible hose 62. The water supply pipe 64 is spirally wound inside the outer shell of the water pump body 1. A refrigeration box 63 is connected to the outer wall of the filter box 42 at the position corresponding to the position of the water supply pipe 64. A heating box 61 is connected to the outer wall of the filter box 42 near the position of the refrigeration box 63. A semiconductor cooling chip 65 is connected at the middle position between the heating box 61 and the refrigeration box 63. The cooling end of the semiconductor cooling chip 65 is in close contact with the outer wall of the refrigeration box 63, and the heating end is in close contact with the outer wall of the heating box 61. A stirring blade is rotatably connected to the inner side of both the heating box 61 and the refrigeration box 63 to facilitate the mixing of the water flow. A return pipe 66 is connected at the middle position of the heating box 61. A control valve 611 is connected to the outer wall of the water supply pipe 64 and the connecting pipe 67 on the same side.

[0038] In the prior art, during the long-term operation of the water pump body 1, the internal equipment is prone to generating a lot of heat, which causes the internal temperature of the water pump body 1 to rise. The rise in temperature can have an adverse effect on the service life of the internal equipment.

[0039] During the rotation of the rotating rod 510, the reciprocating plate 610 reciprocates within the reciprocating groove 68 area. This causes the telescopic hose 62 to draw water from below the filter box 42 during its stretching and contraction, and then transmit it outward through the water supply pipe 64. As the water flows inside the pump body 1 housing, it carries away the heat inside the pump body 1, cooling it down. When the internal temperature detection device of the pump body 1 detects that the internal temperature is higher than the set maximum temperature value, it sends a signal to the electrical control box to control the semiconductor cooling chip 65 to operate. This causes the water flowing inside the water supply pipe 64 to absorb the cold air from the cooling end of the semiconductor cooling chip 65 as it passes through the cooling box 63. The water flows into the inside of the pump body 1, accelerating the absorption of heat inside the pump body 1. After the temperature detection device inside the pump body 1 detects that the internal temperature of the pump body 1 has dropped below the preset minimum temperature value, it sends a signal to the electrical control box to stop the operation of the semiconductor cooling chip 65. The returning water flows into the heating box 61 along the return pipe 66 and is neutralized with the internal hot water before flowing into the filter box 42. When the temperature detection device inside the filter box 42 detects that the mixed returning water causes the overall water temperature inside the filter box 42 to be higher than the preset value, it sends a signal to the electrical control box to stop the operation of the semiconductor cooling chip 65 to prevent the water temperature for irrigation from being too high and affecting crop growth.

[0040] In use, the filtered water flows from the inlet pipe 43 to the pump body 1, causing the propeller blade 58 to rotate. The rotating rod 510 connected to the propeller blade 58 rotates, causing several evenly distributed cross rotating blocks 52 to rotate. The included angle between adjacent cross rotating blocks 52 is 45 degrees, so that when one of the two adjacent cross rotating blocks 52 lifts the movable plate 55, the other cross rotating block 52 will not lift the movable plate 55. The lifted movable plate 55 is inserted into the filter hole 53, reducing the space available for water flow. The staggered angle of the adjacent cross rotating blocks 52 ensures that when the cross rotating blocks 52 lift, adjacent positions will not be lifted, facilitating the continued flow of water. The lifted movable plate 55 lifts the filter screen frame inside the filter hole 53, so that the impurities accumulated on the filter screen frame can be scraped away by the scraper gate 45 to achieve a cleaning effect, so that the impurities do not affect the filtration effect of the filter screen frame on impurities in the water flow.

[0041] The rotating rod 510 drives the transmission wheel 49, which is connected to one end of the connecting rod 412, to rotate via the transmission wheel 49 and the transmission belt 411. During rotation, the reciprocating screw 44, integral with the connecting rod 412, causes the scraper gate 45 to move on the upper surface of the filter plate 46. The transmission wheel 49 on the rotating rod 510 is connected to the vertical half-tooth wheel 410 via the transmission belt 411. The vertical half-tooth wheel 410 and the horizontal half-tooth wheel 410 are interlocked. The horizontal half-tooth wheel 410 is connected to the shaft of the crushing blade 413 via the transmission belt 411. The crushing blades 413 are mutually... The rotating rod 510 is connected by a planetary gear structure to achieve coaxial reversal, allowing the rotating rod 510 to drive the crushing blades 413 to crush impurities entering the water flow from the inlet pipe 43. The reverse-rotating crushing blades 413 crush the impurities more thoroughly. The crushed impurities flow with the water flow to the filter holes 53 on the filter plate 46. The water flows downward from the filter holes 53, where the impurities are filtered down by the filter screen frame inside the filter holes 53. The impurities accumulated on the filter plate 46 are scraped away by the moving scraper gate 45 and pushed into the space above the filter plate 46. The material scraper gate 45 moves to one side, squeezing the accumulated impurities and reducing their space occupation. During the squeezing process, the squeezing block 415 inside the movable box 414 is squeezed, which in turn squeezes the pressure sensor inside the movable box 414. The pressure sensor transmits the detected pressure data to the data processing equipment inside the control box. The data processing equipment compares the detected pressure data value with the preset pressure data value. When the comparison shows that the detected pressure data value is greater than the preset pressure data value, it controls the discharge gate 41 to open and discharge the impurities. The water flow inside the filter box 42 is blocked by the material scraper gate 45. The water will flow outwards. The filter holes 53 on the filter plate 46 corresponding to the impurities will be filled with the compacted impurities and will not leak out. After the scraper gate 45 moves to one end of the filter box 42, it touches the first touch sensor. The first touch sensor transmits a signal to the control box to control the unloading gate 41 to close. After the unloading gate 41 closes, the gate plate 416 of the scraper gate 45 is opened. After the gate plate 416 opens, the scraper gate 45 moves to one end on the reciprocating screw 44 and moves in the opposite direction. After the reverse movement touches the second touch sensor, the gate plate 416 of the scraper gate 45 closes and the scraping operation is performed again.

[0042] During the rotation of the rotating rod 510, the reciprocating plate 610 reciprocates within the reciprocating groove 68 area. This causes the telescopic hose 62 to draw water from below the filter box 42 during its stretching and contraction, and then transmit it outward through the water supply pipe 64. As the water flows inside the pump body 1 housing, it carries away the heat inside the pump body 1, cooling it down. When the internal temperature detection device of the pump body 1 detects that the internal temperature is higher than the set maximum temperature value, it sends a signal to the electrical control box to control the semiconductor cooling chip 65 to operate. This causes the water flowing inside the water supply pipe 64 to absorb the cold air from the cooling end of the semiconductor cooling chip 65 as it passes through the cooling box 63. The water flows into the inside of the pump body 1, accelerating the absorption of heat inside the pump body 1. After the temperature detection device inside the pump body 1 detects that the internal temperature of the pump body 1 has dropped below the preset minimum temperature value, it sends a signal to the electrical control box to stop the operation of the semiconductor cooling chip 65. The returning water flows into the heating box 61 along the return pipe 66 and is neutralized with the internal hot water before flowing into the filter box 42. When the temperature detection device inside the filter box 42 detects that the mixed returning water causes the overall water temperature inside the filter box 42 to be higher than the preset value, it sends a signal to the electrical control box to stop the operation of the semiconductor cooling chip 65 to prevent the water temperature for irrigation from being too high and affecting crop growth.
