In the above process, the threaded rod 3 drives the first cone pulley 22 to rotate through the spline 23 in the rotating process, the first cone pulley 22 and the second cone pulley 30 are engaged and connected, the first cone pulley 22 drives the lead screw 25 to rotate through the second cone pulley 30, the nut 26 in threaded connection with the side wall of the lead screw 25 moves along the axial direction of the lead screw 25 for a certain distance, then the push rod 27 in symmetrical and fixed connection with the side wall of the nut 26 drives the filter plate 28 to move towards the direction close to the water outlet pipe 29 until the filter plate 28 and the water outlet pipe 29 are in abutting contact, and at this time, the filter plate 28 and the plurality of filter holes 36 formed in the inner wall of the filter plate can prevent external impurities from entering the hydrant body 1.
When the piston 16 seals the communicating hole 17, the control valve of the drain hole arranged in the hydrant body 1 is opened, the water accumulated in the hydrant body 1 is discharged, and in the sliding process of the sliding block 11, the sliding block 11 drives the triggering rod 13 fixedly connected with the side wall of the hydrant body to synchronously move, one end of the triggering rod 13 positioned in the rectangular cavity 35 extrudes the switch sensor 34, the switch sensor 34 is in the prior art, the details are not repeated, the switch sensor 34 is subjected to one-time extrusion and then can enable the heating resistor 38 to be powered on for a period of time and then to be powered off, the heating resistor 38 is also in the prior art, and then the heating resistor 38 is powered on and then generates high temperature so as to heat and dry the moist environment in the hydrant body 1, so that the inside of the hydrant body 1 is kept dry, parts in the hydrant body 1 are not easy to rust, and the service life of the hydrant body is prolonged.
The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
