[0016] Beneficial Effects

[0017] The present invention provides a water well cleaning and silt removal device. Compared with the prior art, it has the following beneficial effects:

[0018] (1) The well cleaning and silt removal device adjusts the distance between the movable frame and the connecting frame through an electric push rod, causing the transmission rod to drive the connecting rod to rotate with the connection point between the connecting rod and the movable frame as the reference, so that the rubber wheel at the bottom of the connecting rod moves outward, and the rubber wheel is adjusted to a state of contacting the inner wall of the well. This enables the device to move in the well through the rubber wheel when the driving motor drives the synchronous wheel to drive the rubber wheel to rotate, avoiding the limitation of the descending height by the length of the lead screw when adjusting the position through the lead screw.

[0019] (2) The well cleaning and silt removal device, through the setting of the driving pipe, since the driving pipe is rotationally connected to the limiting pipe through a bearing, and the magnetic tile is fixed to the outside of the driving pipe through a limiting frame, and the centers of the fixing frame and the limiting frame coincide, and the coil is located outside the magnetic tile. After the coil is energized, it can drive the driving pipe to rotate through the magnetic tile. When the driving pipe drives the transmission frame to rotate, the connecting pipe will drive the counterweight to rotate, and the centrifugal force generated when the counterweight rotates drives the connecting pipe to move outward from the transmission frame until the outside of the counterweight contacts the inner wall of the well. When the counterweight rotates, the brush on the outside of the counterweight can clean the inner wall of the well, and the arc surface on the outside of the counterweight can prevent the counterweight from getting stuck. This method can keep the brush in contact with the well wall through the centrifugal force during rotation to clean the well wall, and the connecting pipe can be reset by the internal return spring when it stops rotating, eliminating the need for manual adjustment of the device according to the diameter of the well, so as to improve efficiency.

[0020] (3) The well cleaning and silt removal device can avoid the driving pipe affecting the connecting hose when rotating through the rotary joint. The length of the connecting hose needs to match the well depth to facilitate the delivery of water to the shunt pipe at the bottom of the driving pipe. The shunt pipe at the bottom of the driving pipe guides the water flow into the fan-shaped nozzle, and the fan-shaped nozzle can generate a fan-shaped water flow perpendicular to the well wall, thereby flushing the well wall. At the same time, when the driving pipe rotates, it will also drive the shunt pipe to rotate, so that the water flow covers the entire well wall. And the fan-shaped nozzle is located below the counterweight, which can wet the dry silt on the surface of the well wall before brushing the well wall, so as to facilitate the cleaning of the silt by the brush.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-2 , the present invention provides a technical solution: a water well cleaning and silt removal device includes a support frame 1, a pulley 11 is installed above the support frame 1, a recovery steel cable 12 is fitted and installed above the pulley 11, and a recovery mechanism 2 for winding the recovery steel cable 12 is installed above the support frame 1. The recovery mechanism 2 includes a winding motor 21 and a wheel frame 22 fixedly installed above the support frame 1. A winch 23 is movably installed at the top of the wheel frame 22, and one end of the recovery steel cable 12 is wound around the outside of the winch 23.

[0030] Specifically, the support frame 1 can limit the position of the pulley 11, guide the recovery steel cable 12 through the pulley 11, one end of the recovery steel cable 12 is fixed to the outside of the winch 23, and the winch 23 is driven by the winding motor 21 to rotate to wind the recovery steel cable 12, so as to quickly recover the equipment from the well.

[0031] Please refer to Figure 3, one end of the recovery steel cable 12 is installed with a support mechanism 3 for restricting the rotation angle of the connecting rod 33. The support mechanism 3 includes a movable frame 31 fixedly installed at one end of the recovery steel cable 12. A transmission rod 32 is movably installed on the outer side of the movable frame 31. The bottom end of the transmission rod 32 is movably installed with a connecting rod 33. A connecting frame 34 is movably installed on the inner side of the connecting rod 33. An electric push rod 35 is installed between the connecting frame 34 and the movable frame 31. The bottom end of the connecting rod 33 is movably installed with a rubber wheel 36. A transmission component 37 for adjusting the position of the connecting frame 34 is installed on the outer side of the connecting rod 33. The transmission component 37 includes a driving motor 371 fixed on the outer side of the connecting rod 33. A synchronous pulley 372 is fixedly installed on the outer side of the rotating shaft of the driving motor 371. A synchronous belt 373 is fitted and installed on the outer side of the synchronous pulley 372. A synchronous pulley 372 is also installed at one end of the central axis of the rubber wheel 36, and the synchronous pulley 372 at one end of the central axis of the rubber wheel 36 is located inside one end of the synchronous belt 373.

[0032] Specifically, the distance between the movable frame 31 and the connecting frame 34 is adjusted by the electric push rod 35, so that the transmission rod 32 drives the connecting rod 33 to rotate with the connection point between the connecting rod 33 and the movable frame 31 as the reference, so that the rubber wheel 36 at the bottom end of the connecting rod 33 moves outward, and the rubber wheel 36 is adjusted to a state of contacting the inner wall of the water well, so that when the driving motor 371 drives the synchronous pulley 372 to drive the rubber wheel 36 to rotate through the synchronous belt 373, the height of the underground adjustment device can be adjusted.

[0033] Please refer to Figure 3-4 , a driving mechanism 4 for driving the cleaning mechanism 5 to rotate for cleaning is installed at the center of the support mechanism 3. The driving mechanism 4 includes a limiting tube 41 fixed at the center of the movable frame 31. Bearings 42 are fixedly installed on the inner sides of both ends of the limiting tube 41. A driving tube 43 is inserted through the centers of the bearings 42. A limiting frame 44 is fixedly installed on the outer side of the driving tube 43. A magnetic tile 45 is fitted and installed on the outer side of the limiting frame 44. A fixing frame 46 is fixedly installed on the inner wall of the driving tube 43. A coil 47 is wound inside the fixing frame 46.

[0034] Specifically, the limiting tube 41 can limit the position of the coil 47 inside the fixing frame 46. Since the driving tube 43 is rotatably connected to the limiting tube 41 through the bearing 42, and the magnetic tile 45 is fixed to the outer side of the driving tube 43 through the limiting frame 44, and the centers of the fixing frame 46 and the limiting frame 44 coincide, and the coil 47 is located outside the magnetic tile 45, the driving tube 43 can be driven to rotate by the magnetic tile 45 after the coil 47 is energized.

[0035] Please refer to Figure 1 And Figure 5-6, the cleaning mechanism 5 includes a transmission frame 51 fixed to the outer side of the bottom end of the drive pipe 43. An eccentric component 52 is movably installed on the outer side of the transmission frame 51. The eccentric component 52 includes a connecting pipe 521 inserted and installed inside the transmission frame 51. A return spring 522 is inserted and installed on the outer side of the connecting pipe 521. One end of the connecting pipe 521 is fixedly installed with a counterweight 523. Brush bristles 524 are arranged on the outer side of the counterweight 523.

[0036] A sliding connection is formed between the connecting pipe 521 and the transmission frame 51. The inside of the connecting pipe 521 is provided with a reinforcing rib with a "cross" cross-section. The counterweight 523 is a semi-cylindrical structure, and the arc surface points outward. The brush bristles 524 are arranged on the outer side of the arc surface of the counterweight 523. The cleaning mechanism 5 further includes a shunt pipe 53 fixedly installed at the bottom end of the drive pipe 43 and a rotary joint 55 at the top end. The branch end of the shunt pipe 53 is fixedly installed with a sector nozzle 54. The top end of the rotary joint 55 is fixedly installed with a connecting hose 56. The bottom end of the shunt pipe 53 is provided with a horizontal "cross" branch. The sector nozzle 54 is installed on the outer side of the branch of the shunt pipe 53. The connecting hose 56 forms a rotational connection with the drive pipe 43 through the rotary joint 55.

[0037] Specifically, the transmission frame 51 can limit the position of the connecting pipe 521. The outer end of the connecting pipe 521 is connected to the counterweight 523. When the drive pipe 43 drives the transmission frame 51 to rotate, the connecting pipe 521 will drive the counterweight 523 to rotate. The centrifugal force generated by the counterweight 523 during rotation drives the connecting pipe 521 to move outward from the transmission frame 51 until the outer side of the counterweight 523 contacts the inner wall of the water well. When the counterweight 523 rotates, the brush bristles 524 on the outer side of the counterweight 523 can clean the inner wall of the water well, and the arc surface on the outer side of the counterweight 523 can prevent the counterweight 523 from getting stuck. The shunt pipe 53 at the bottom end guides water flow into the sector nozzle 54. The sector nozzle 54 can generate a sector water flow perpendicular to the well wall, thereby flushing the well wall. At the same time, when the drive pipe 43 rotates, it will also drive the shunt pipe 53 to rotate, so that the water flow covers the entire well wall. The rotary joint 55 can prevent the drive pipe 43 from affecting the connecting hose 56 during rotation. The length of the connecting hose 56 needs to match the well depth to facilitate the delivery of water to the shunt pipe 53 at the bottom of the drive pipe 43.

[0038] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0039] During operation, the distance between the movable frame 31 and the connecting frame 34 is adjusted by the electric push rod 35, so that the transmission rod 32 drives the connecting rod 33 to rotate with the connection between the connecting rod 33 and the movable frame 31 as the reference, so that the rubber wheel 36 at the bottom end of the connecting rod 33 moves outward, and the rubber wheel 36 is adjusted to a state of contacting the inner wall of the water well. When the driving motor 371 drives the synchronous pulley 372 to drive the rubber wheel 36 to rotate through the synchronous belt 373, the height of the downhole adjustment device can be adjusted. This method enables the device to move underground through the rubber wheel 36, avoiding the limitation of the descending height by the length of the lead screw when adjusting the position through the lead screw. Since the driving pipe 43 is rotatably connected to the limiting pipe 41 through the bearing 42, and the magnetic tile 45 is fixed to the outside of the driving pipe 43 through the limiting frame 44, and the fixing frame 46 coincides with the center of the limiting frame 44, and the coil 47 is located outside the magnetic tile 45. After the coil 47 is energized, it can drive the driving pipe 43 to rotate through the magnetic tile 45. When the driving pipe 43 drives the transmission frame 51 to rotate, the connecting pipe 521 will drive the counterweight 523 to rotate. The centrifugal force generated by the counterweight 523 during rotation drives the connecting pipe 521 to move outward from the transmission frame 51 until the outside of the counterweight 523 contacts the inner wall of the water well. When the counterweight 523 rotates, the brush bristles 524 on the outside of the counterweight 523 can clean the inner wall of the water well, and the arc surface on the outside of the counterweight 523 can prevent the counterweight 523 from getting stuck. This method can keep the brush bristles 524 in contact with the well wall through the centrifugal force during rotation to clean the well wall, and when it stops rotating, the connecting pipe 521 is reset by the internal return spring 522, eliminating the operation of manually adjusting the device according to the diameter of the water well, so as to improve the efficiency. The rotary joint 55 can prevent the driving pipe 43 from affecting the connecting hose 56 when it rotates. The length of the connecting hose 56 needs to match the well depth to facilitate the delivery of water to the shunt pipe 53 at the bottom of the driving pipe 43. The water flow is guided into the sector nozzle 54 through the shunt pipe 53 at the bottom of the driving pipe 43. The sector nozzle 54 can generate a sector water flow perpendicular to the well wall, thereby flushing the well wall. At the same time, when the driving pipe 43 rotates, it will also drive the shunt pipe 53 to rotate, so that the water flow covers the entire well wall. And the sector nozzle 54 is located below the counterweight 523, which can wet the dry silt on the surface of the well wall before brushing the well wall, so as to facilitate the cleaning of the silt by the brush bristles 524.
