[0002] Water supply and drainage generally refer to the urban water supply system and drainage system. In buildings, water supply and drainage is an important project, ensuring the water supply and drainage work for later residence. Since water is prone to freezing in winter, which can cause pipeline blockage, in order to ensure the normal operation of the water supply and drainage pipelines, anti-freezing measures need to be taken for the pipelines.

[0003] A patent document CN217419827U that has been published proposes an anti-freezing device for building water supply and drainage, including an anti-freezing heating box. The left side surface of the anti-freezing heating box is fixedly communicated with a water inlet pipe, and the right side surface of the anti-freezing heating box is fixedly communicated with a water outlet pipe. Heat preservation sleeves are sleeved on the outer surfaces of both the water inlet pipe and the water outlet pipe. Through the cooperation of the heating components in the anti-freezing heating box, the spiral heating rod heats and raises the temperature of the water entering the anti-freezing heating box, increasing the outlet water temperature of the water supply and drainage. At the same time, a heating wire is wound around the conveying pipe, and through the cooperation of the heating wire and the heat preservation sleeve, the water supply and drainage pipeline is insulated to prevent freezing during transportation in winter.

[0004] The inventor found through research that it still has the following problems:

[0005] 1. There is no device for quick installation and disassembly on the spiral heating rod of this device, so the spiral heating rod cannot be quickly disassembled and assembled for repair, reducing the operation efficiency;

[0006] 2. The heat preservation sleeve of this device can only be suitable for heat preservation of water pipes of one specification, and the applicability is not high.

[0007] Therefore, an anti-freezing device for building water supply and drainage is needed to solve the problems raised in the above background technique. Content of the Utility Model

[0008] In view of the above problems, the utility model provides an anti-freezing device for building water supply and drainage.

[0009] The utility model provides the following technical solution: An anti-freezing device for building water supply and drainage, including a transition box. Both sides of the transition box are provided with water conveying pipes facilitating water supply and drainage. A heat preservation sleeve is sleeved on the outer side of the water conveying pipe. A locking mechanism facilitating its installation and disassembly is provided on the outer side of the heat preservation sleeve. A heating coil penetrates through the inner side of the transition box. A driving motor is installed on one side of the transition box. The output end of the driving motor extends to the inner side of the transition box and is connected with a turntable. One end of the heating coil is connected with one side of the turntable through a connection mechanism facilitating disassembly and assembly;

[0010] The connecting mechanism includes a socket provided on one side of the turntable.
