Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 8, the environment-friendly cleaning device for irrigation and water conservancy projects of the present invention includes a housing 100, a filter element pipe 400, a bidirectional threaded pipe 300, and a floating filter pipe 500. The housing 100 is horizontally disposed, and has a water inlet 104 and a water outlet 103 at the lower side and the right end thereof, respectively, and a collection chamber 101 communicated with the left end thereof. The filter element duct 400 is horizontally disposed inside the housing 100, and an arc-shaped hole 401 extending in a length direction thereof is provided on a right end outer peripheral wall of the filter element duct 400. The bidirectional threaded pipe 300 is rotatably installed in the housing 100, and the left end of the bidirectional threaded pipe is inserted into the right end of the filter element pipe 400, the right end surface of the bidirectional threaded pipe 300 is connected with the fan blade 303, the outer peripheral wall surface of the bidirectional threaded pipe 300 is provided with a first spiral groove 304 and a second spiral groove 305, which have opposite rotation directions, and the right ends of the first spiral groove 304 and the second spiral groove 305 are communicated with the annular groove 306. The floating filter tube 500 is arranged outside the filter element pipeline 400 in a left-right sliding manner, the left end of the floating filter tube is connected with the inner peripheral wall of the shell 100 in a sliding and sealing manner, and the outer end of the outer peripheral wall of the right half part of the floating filter tube 500 is provided with a dirt pushing plate 501 inclined towards the left.
The inner side wall of the right end of the floating filter pipe 500 is rotatably provided with a first cam block 700 around the radial direction thereof, the inner side of the first cam block 700 is coaxially and rotatably provided with a second cam block 800, and the first cam block 700 and the second cam block 800 are connected through a torsion spring 803. Under the normal state, the first cam block 700 is positioned in the arc-shaped hole 401 and at the rightmost end of the arc-shaped hole 401, the second cam block 800 is positioned in the annular groove 306, the torsion spring 803 between the first cam block 700 and the second cam block 800 has a pretightening force, and one end of the second cam block 800, which is far away from the rotation axis of the second cam block, inclines towards the direction close to the first spiral groove 304 and the second spiral groove 305.
During normal work, the water pump is gone into shell 100 and the space that the filter tube 500 encloses that floats with water through water inlet 104 pump in, and the left end equipartition of filter tube 500 that floats has a plurality of filtration pores 502, and filter core pipeline 400 sets up to hollow out construction, and the inside of filter core pipeline 400 is provided with filter screen 900, and water passes through filtration pore 502 and accomplishes the filtration through filter tube 500 that floats, filter core pipeline 400 and filter screen 900, and the back is discharged through delivery port 103 (flabellum 303 intercommunication delivery port 103) through two-way screwed pipe 300. In the normal drainage process, the water flow drives the fan blade 303 to rotate counterclockwise, and further drives the bidirectional threaded pipe 300 to rotate counterclockwise. During the rotation of the bidirectional threaded pipe 300, the bidirectional second cam block 800 slides in the annular groove 306, and at this time, the bidirectional threaded pipe 300 can overcome the pre-tightening force of the torsion spring 803 when rotating.
When the floating filter tube 500 is blocked by the impurities in the water, the water flow at the water outlet 103 is weakened, and the rotation speed of the bidirectional threaded tube 300 is reduced. The water continues to be pumped to increase the external pressure of the floating filter tube 500 and push the floating filter tube 500 to move to the left, and the impurities are pushed to the collection chamber 101 by the push-dirty plate 501 while the floating filter tube 500 moves to the left. In the process that the floating filter tube 500 moves leftwards, the second cam block 800 is dragged into the intersection point of the first spiral groove 304 and the second spiral groove 305 (the first spiral groove 304 and the second spiral groove 305 divide the outer circular surface of the bidirectional spiral tube 300 into a plurality of diamond blocks) in cooperation with the rotation of the bidirectional spiral tube 300, and at this time, because the rotation speed of the bidirectional spiral tube 300 is reduced, the rotating force of the bidirectional spiral tube cannot overcome the pre-tightening force of the torsion spring 803, so that the second cam block 800 moves along the first spiral groove 304, that is, moves leftwards under the driving of the floating filter tube 500.
Meanwhile, the first cam block 700 moves along the arc-shaped hole 401, so that the first cam block 700 rotates by a certain angle and the torsion force of the torsion spring 803 is gradually released, and the pretightening force of the torsion spring 803 is gradually reduced. Further left movement of the first cam block 700 gradually opens the arc-shaped hole 401, water enters the bidirectional threaded pipe 300 from the arc-shaped hole 401 to push the fan blade 303 to rotate, the water flow gradually increases, and the rotating speed of the bidirectional threaded pipe 300 is gradually increased. More closely, as the floating filter tube 500 moves to the left, part of the impurities are pushed into the collection chamber 101, the water flow is further lifted along with the removal of the impurities, and the fan blade 303 drives the bidirectional threaded tube 300 to rotate at a constant speed. When the rotating force of the bidirectional threaded pipe 300 is enough to overcome the pre-tightening force of the torsion spring 803, the second cam block 800 is pushed by the vertex of the diamond block at the intersection point of the first spiral groove 304 and the second spiral groove 305, and rotates counterclockwise along the axis thereof, so as to align with the second spiral groove 305 and move along the second spiral groove 305, thereby driving the floating filter pipe 500 to move rightwards for resetting.
During the process that the floating filter pipe 500 moves to the right, if the blockage occurs again, the flow rate of the water outlet 103 is reduced, and the rotation speed of the bidirectional threaded pipe 300 is reduced, so that the rotation force of the bidirectional threaded pipe 300 is not enough to overcome the torsion force of the torsion spring 803, and meanwhile, the floating filter pipe 500 moves to the left under the action of external pressure, and the second cam block 800 is reversed again to enter the first spiral groove 304 and moves along the first spiral groove 304. If the congestion is not serious, the floating filter tube 500 is floated, the flow rate is quickly recovered until the rotating force of the bidirectional threaded tube 300 is enough to overcome the pre-tightening force of the torsion spring 803, and the second cam block 800 is reversed again to enter the second spiral groove 305 to push the floating filter tube 500 to the right again. Through the scheme, the floating filter pipe 500 is controlled to move and clean under the combined action of the pressure and the water flow speed, and the condition that judgment is not accurate enough due to the fact that only unilateral control schemes such as pressure control are adopted is avoided, and equipment is caused to make wrong actions.
