Technical Field

[0001] The utility model belongs to the field of heating facilities, and in particular relates to an automatic heating device for preventing common pipes from freezing and cracking in a wall-mounted boiler heating system. Background Art

[0002] Some residential projects in Northwest China use wall-mounted boilers for indoor heating, but lack heating in common areas. During winter, because the indoor temperatures in these areas fail to reach the designed temperature, pipes in the manholes often freeze and crack. Water pipes in the subfloor are also susceptible to freezing and cracking, disrupting residents' daily lives. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic heating device for preventing common pipes from freezing and cracking in a wall-mounted boiler heating system, so as to solve the problem that pipes are easily frozen and cracked due to the low indoor temperature in public areas in winter in the wall-mounted boiler heating system.

[0004] The technical solution of the utility model is: an automatic heating device for preventing common pipes from freezing and cracking in a wall-mounted boiler heating system, an electric heating tape is wrapped around the outside of the pipe in the pipe well, the electric heating tape is connected to the distribution box through a first power connection box, a first temperature sensor is provided in the pipe, and the first temperature sensor is connected to the distribution box through a first thermostat.

[0005] As a further improvement of the present invention, a high-temperature radiation electric heater and a second temperature sensor are provided in the public corridor. The high-temperature radiation electric heater is connected to the distribution box through a second power junction box, and the second temperature sensor is connected to the distribution box through a second thermostat.

[0006] As a further improvement of the utility model, it also includes a solar photovoltaic system, which is connected to the distribution box.

[0007] The beneficial effects of this utility model are as follows: An electric heating cable is wrapped around the exterior of the pipe in the pipe well. A first temperature sensor detects the temperature inside the pipe. The heating cable is automatically activated and deactivated based on the temperature signal from the first temperature sensor, heating the pipe at low temperatures to prevent freezing and cracking. A high-temperature radiant heater is installed in the public corridor. A second temperature sensor detects the indoor temperature. The heating is automatically activated and deactivated based on the temperature signal from the second temperature sensor. By heating the indoor space, the water supply pipe in the cushion layer is prevented from freezing and cracking. This utility model uses solar power for power, making it low-carbon and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
