Anti-freezing device for tap water pipe

Abstract

The invention discloses an anti-freezing device for tap water pipe. The device comprises a water pipe and a housing, the water pipe is sleeved with the housing, a heating layer is installed on the inner wall of the water pipe, the heating layer comprises multiple resistors, a rotary ring is rotatably connected with the inner wall of the water pipe, a worm rod is installed in the rotary ring, the rotary ring is fixedly connected with the worm rod through multiple connecting shafts, an underwater rotary fan is sleeved with one end of the worm rod, the underwater rotary fan comprises a connectingring and multiple blades, a rotary shaft is installed in the housing, the rotary shaft is rotatably inserted in the water pipe, a worm wheel sleeves the end, close to the water pipe, of the rotary shaft, and the worm rod meshes with the worm wheel. By installing the under water rotary fan which can be rotated in the water pip, a current is generated in the rotation process, heat is generated whenthe current passes through the resistors, passing water is heated correspondingly, and the freezing of the water pipe by water flow can be effectively prevented with water with the temperature of higher than 0 DEG C flowing in the water pipe.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to an antifreeze device for water pipes. Background technique [0002] Every city has a water supply and drainage system. The water supply and drainage system transports tap water through water pipes. The temperature in winter is low. When the environment is below zero, if the water in the water pipes does not flow or the temperature is low, the water will The water in the pipe will inevitably freeze, and the frozen water pipe cannot be used. [0003] If the water pipe is frozen, it will be very troublesome to thaw. Most households will use hot water to thaw, but using hot water to thaw is very slow, takes a long time, and consumes more hot water. By ensuring that the inside of the water pipe For the flow of water, for the end close to the faucet, if the faucet is turned on for a long time, it is a waste of water resources and cannot be kept open for a long time.
