The operation of the rotary water delivery pump is synchronous to the water injection in the rotary water delivery tank 1 through the water inlet pipe 2 and the bypass pipe 8, when the water level in the rotary water delivery tank 1 reaches the set closing water level of the float valve 3, the float valve 3 is closed, only the water in the bypass pipe 8 can enter the water tank, the water quantity entering the water tank by the bypass pipe 8 is greatly smaller than the water yield of the rotary water delivery pump, and the overflow quantity of the water tank can be effectively reduced.
The inside diameter shrinkage mechanism 5 comprises a cylinder 51, a water inlet short pipe 52, a water outlet pipe 53, a rubber pipe 54, a ring-shaped rubber plunger 55, a ring-shaped column 56, a buoyancy member 57, a rubber plunger 58, a connecting column 59, a roller 510, a sliding block 511, a pressing plate 512 and a return spring 513, wherein a cylindrical cavity 5102 is arranged in the middle of the cylinder 51, a ring-shaped cavity 5101 is arranged at the outer side of the cylindrical cavity 5102, a plurality of circular cavities 5103 are uniformly arranged between the cylindrical cavity 5102 and the ring-shaped cavity 5101 along the circumference, and three groups of circular cavities 5103 are arranged in the embodiment; the upper end of the circular cavity 5103 is communicated with the upper end of the circular cavity 5101, the upper end and the lower end of the cylinder 51 are respectively provided with a water inlet short pipe 52 and a water outlet pipe 53 in a penetrating way, the water inlet short pipe 52 and the water outlet pipe 53 extend into the cylindrical cavity 5102, the water inlet short pipe 52 is connected with the water outlet pipe 53 through a rubber pipe 54, the lower end of the cylinder 51 is provided with a circular column 56, the upper end of the circular column 56 penetrates through the bottom of the cylinder 51 and extends into the circular cavity 5101, the circular column 56 is in clearance fit with the cylinder 51, the upper end of the circular column 56 is provided with a circular rubber plunger 55, the circular rubber plunger 55 is in interference fit with the circular cavity 5101, the bottom of the circular column 56 is provided with a hollow buoyancy member 57, the side wall of the cylindrical cavity 5102 is connected with a sliding block 511 which can slide along the radial direction of the circular column, the other end of the sliding block 511 is an inclined wall and extends into the circular cavity 5103, one end of the sliding block 511, which is positioned in the cylindrical cavity 5102, a pressing plate 512 is fixedly arranged between the inner wall of the cylindrical cavity 5102 and a reset spring 513, and the reset spring 513 is in a relaxed state; the rubber plunger 58 is in interference fit in the round cavity 5103, the bottom fixedly connected with spliced pole 59 of rubber plunger 58, the bottom of spliced pole 59 is equipped with gyro wheel 510, gyro wheel 510 and the oblique wall end butt of sliding block 511, and inlet stub 52 passes through the water piping connection head and links to each other with bypass pipe 8.
Along with the upward movement of the ring-shaped rubber plunger 55 by the upward buoyancy member 57 of the water level in the water transfer tank 1 through the ring-shaped column 56, the upward movement of the ring-shaped rubber plunger 55 presses the gas in the ring-shaped cavity 5101 into the circular cavity 5103, so that the gas pressure in the circular cavity 5103 is increased, the gas pressure in the circular cavity 5103 can squeeze the rubber plunger 58, the rubber plunger 58 is pushed to move downwards, the downward movement of the rubber plunger 58 pushes the sliding block 511 to move inwards through the connecting column 59 and the roller 510, the pressing plate 512 compresses the rubber tube 54, the return spring 513 is stretched, the pressing plate 512 presses the rubber tube 54 inwards, the liquid flow area in the rubber tube 54 is reduced, and the water yield of the water outlet pipe 53 is reduced along with the reduction of the liquid flow area of the rubber tube 54; when the water level in the water transfer tank 1 drops, the sum of the air pressure in the ring cavity 5101 and the upward pulling force of the return spring 513 is larger than the buoyancy provided by the buoyancy member 57, the rubber tube 54 moves downwards while the rubber plunger 58 rises, the pressing plate 512 moves outwards, the rubber tube 54 is stretched outwards, and the water yield is increased; this arrangement enables the water outlet of the bypass pipe 8 to be adjusted as much as the water in the transfer tank 1, further reducing the overflow of water in the transfer tank 1.
As a further preferable example, the interference fit between the annular rubber plunger 55 and the annular cavity 511 is 5-8mm, so as to improve the tightness and prevent external water from being filled above the annular rubber plunger 55, and when the interference fit is too large, the annular rubber plunger 55 is not easy to move up and down, which is not beneficial to compression of gas in the annular cavity 5101.
Further, a gate valve 4 is arranged on the water inlet pipe 2, and the gate valve 4 is closer to the water inlet side of the water inlet pipe 2 than the joint of the water inlet pipe 2 and the bypass pipe 8; when the float valve 3 is overhauled, the gate valve 4 is closed, and the supply of external water is avoided.
Further, the wall thickness of the rubber tube 54 is not more than 8mm, wherein the hardness of the rubber used for the rubber tube 54 is 25-30 degrees; when the wall thickness of the rubber tube 54 is too large, the hardness of the rubber tube 54 is too large, which is unfavorable for the expansion and contraction of the rubber tube 54, the rubber tube 54 is more preferably 5-7mm, and the rubber tube 54 is easily damaged due to too thin.
Furthermore, the unilateral fit clearance between the annular column 56 and the cylinder 51 is 2-3mm, so that a certain limiting guide function is realized, and the cylinder 51 is prevented from tilting in the lifting process; when the fit clearance between the annular column 56 and the cylinder 51 is too small, the annular column 56 is not beneficial to telescoping in the cylinder 51; when the fit clearance between the annular column 56 and the cylindrical body 51 is too large, the vertical lifting of the annular column 56 is not facilitated, so that the fit clearance between the annular column 56 and the cylindrical body 51 is preferably 2-3mm.
Further, a fixing ring 7 is fixed on the outer side of the water inlet short pipe 52, and the fixing ring 7 is fixedly arranged on the fixing frame 6 through bolts; this arrangement facilitates the disassembly, replacement and maintenance of the inside diameter shrinkage mechanism 5.
Further, the width of the ring cavity 5101 is larger than the inner diameter of the circular cavity 5103, i.e., the volume of the ring cavity 5101 is larger than the volume of the circular cavity 5103; when the gas in the larger volume ring cavity 5101 is compressed by the ring-shaped rubber plunger 55, a larger pressure can be provided to push the rubber plunger 58 downward.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
