A device for preventing freezing of a water supply pipe is provided to prohibit the supply of water from being stopped and to cut down the manpower and time required for the replace of the damaged water supply pipe. A device for preventing freezing of a water supply pipe comprises a first circulation unit(20), an inlet pipe(31), a second circulation unit(20a), a connecting pipe(23), and a discharge pipe(40). The first circulation unit is formed with a hollow space inside, and a semi-circular combining unit positioned at one side to cover a part of the outside of the water supply pipe. The inlet pipe is connected with the water supply pipe, passing through the rear end of the first circulation unit. The second circulation unit is positioned at the combining port combined with the circulation unit, and formed with a hollow space corresponding to the hollow space of the circulation unit inside, and a semi-circular combining unit positioned at one side to cover another part of the outside of the water supply pipe. The connecting pipe is connected between the first and second circulation units. The discharge pipe is taken out from the rear end of the second circulation unit and connected with the water supply pipe. |
