[0022] The top of the second connecting pipe 204 is fixedly installed with a pressure relief valve 205, and the top of the second connecting pipe 204 is threadedly connected with a water connection plug 206.

[0023] The inner wall of the heating box 201 is fixedly provided with a heater 207, the inner bottom wall of the heating box 201 is fixedly provided with a temperature sensor 208, and the bottom of the heating box 201 is threadedly connected with a drainage plug 209.

[0024] The outer surface of the second winding belt 5 is fixedly connected with a fixed plate 9 and a third magic tape 8, and one end of the second winding belt 5 is fixedly connected with a second square frame 6.

[0025] One side of the other end of the second winding belt 5 is fixedly connected with a fourth magic tape 7, and the other end of the second winding belt 5 and the fourth magic tape 7 are both drawn out from the first square frame 10.

[0026] The inside of the fixed plate 9 is fixedly connected with the second connecting pipe 204, so as to fix the second connecting pipe 204.

[0027] The spring heating hose 203 has a special spring structure and good flexibility, can be tightly wound around the outer periphery of the pipeline, and can transfer heat to the pipeline through the hot water flowing in the inside to prevent the water in the pipeline from freezing.

[0028] Example one: district residential water supply and drainage pipeline anti-freezing

[0029] Reference Figures 1-4 In the winter water supply and drainage construction of a new district in the north, the construction personnel need to carry out anti-freezing treatment on the outdoor buried water supply and drainage pipeline. The water supply and drainage pipeline in the district has various specifications, including 50mm, 80mm and 100mm, etc. The construction personnel first select the spring heating hose 203 with appropriate length according to the diameter of the pipeline, and tightly wrap it around the outer periphery of the pipeline. For the pipeline with a diameter of 50mm, the spring heating hose 203 can be well fitted, and its flexibility ensures the tight contact. Then, the first winding belt 1 is placed at the bottom of the pipeline, and after adjusting the tension through the first square frame 10, it is fixed by the second magic tape 4 and the first magic tape 3. Then, the second winding belt 5 is fixed on the top of the pipeline in the same way, the power supply of the heater 207 in the heating box 201 is connected, and the heating of the pipeline is started. During the whole winter, the temperature sensor 208 monitors in real time to ensure that the temperature in the heating box 201 is normal, and there is no safety problem caused by excessive pressure. When the temperature rises in spring, the construction personnel turn off the heater 207, open the water plug 206 and the drainage plug 209, and drain the residual liquid, and properly store the device.

[0030] Working principle; the construction personnel first need to tightly and uniformly wrap the spring heating hose 203 around the outer periphery of the water supply and drainage pipeline. The special spring structure of the spring heating hose 203 gives it good flexibility, which can adapt to pipelines with various diameters and ensure full adhesion to the outer surface of the pipeline, thus building an efficient channel for subsequent heat transfer.

[0031] Then the first winding band 1 is placed at the bottom of the pipeline, the part of the first winding band 1 with the second magic tape 4 and the first magic tape 3 are simultaneously passed through the first square frame 10, and the second magic tape 4 and the first magic tape 3 are mutually pasted, so that the first winding band 1 is stably fixed at the bottom of the pipeline.

[0032] Through the same operation, the second winding band 5 is fixed at the top of the pipeline, so that displacement or falling of the device in use is prevented.

[0033] When the whole anti-freezing device is installed, the construction personnel connects the power supply of the heater 207 in the heating box 201, and the heater 207 starts to work to heat the liquid pre-injected in the heating box 201.

[0034] With the temperature of the liquid in the heating box 201 rising, the heated liquid flows into the spring heating hose 203 tightly wound on the pipeline through the first connecting pipe 202. Since the spring heating hose 203 is in close contact with the pipeline, heat can be quickly and efficiently transferred from the spring heating hose 203 to the pipeline, thereby increasing the temperature of the pipeline and preventing the water in the pipeline from freezing.

[0035] During the heating process, the temperature sensor 208 on the bottom wall of the heating box 201 monitors the temperature of the liquid in the box in real time. When the temperature sensor 208 detects that the temperature of the liquid in the heating box 201 exceeds the preset safety threshold, the pressure relief valve 205 at the top of the second connecting pipe 204 automatically opens to release part of the hot gas or liquid in the heating box 201, thereby reducing the pressure in the box and avoiding safety accidents caused by excessive pressure, and ensuring the safe and stable operation of the whole device.

[0036] When the anti-freezing device is not needed, such as when the temperature rises or the pipeline does not need anti-freezing protection, the construction personnel can first turn off the power supply of the heater 207. Then, the water plug 206 at the top of the second connecting pipe 204 and the drain plug 209 at the bottom of the heating box 201 are unscrewed to drain the residual liquid in the second connecting pipe 204 and the heating box 201, facilitating maintenance and storage of the device and prolonging the service life of the device.

[0037] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
