At the same time, the pipeline can be thawed by two heating methods, which is convenient for workers to choose a suitable thawing method according to the conditions on site. In this embodiment, it mainly includes a thawing box 1. The cross-section of the bottom end of the thawing box 1 is a semicircular concave surface.

[0029] The bottom end of the thawing box 1 is detachably provided with a shielding plate 2, through which the internal structure of the thawing box 1 can be shielded when the device is not in use to avoid blockage caused by excessive dust. A tool slot 10 is fixedly provided in the middle of the top of the shielding plate 2. Tools such as towels and knives required for thawing can be placed in the working slot for easy operation.

The position of the thawing box 1 can be fixed by the limiting mechanism 3, so that the concave surface of the thawing box 1 is always in contact with the pipeline, which is convenient for the subsequent thawing work of the pipeline.

[0031] In order to heat the interior of the heating chamber. In this embodiment, see Figure 3 and Figure 4 A heating chamber 4 is provided inside the thawing box 1, and a heating module 5 for heating the heating chamber 4 is fixedly provided inside the heating chamber 4. The heating module 5 includes a heating block 51 fixedly provided at the top end of the heating chamber 4, and the heating block 51 is centrally controlled by a control module. The heating block 51 is a mature prior art and will not be described in detail here. An insulating pad 52 is provided between the heating block 51 and the thawing box 1. The interior of the heating chamber 4 is heated by the heating block 51 to facilitate subsequent thawing operations.

[0032] To thaw pipes of different materials. Figure 1-Figure 4 , the heating chamber 4 is provided with an air supply mechanism 6 that runs through the thawing box 1 in the vertical direction. The air supply mechanism 6 includes a fan 61 with a motor that is fixedly installed and runs through the top of the thawing box 1 at both ends of the handle 8, and the motor is centrally controlled by the control module. A plurality of air vents 62 are provided on the concave surface at the lower part of the heating chamber 4. The air can be heated by the air supply mechanism 6, and the heated air is transmitted to the pipeline for heating, so that the pipeline is thawed by air heating. The heating chamber 4 is provided with a water supply mechanism 7 that runs through the length direction of the thawing box 1. The water supply mechanism 7 includes a heating water pipe 71 that is fixedly installed inside the heating chamber 4, and the heating water pipe 71 is located between the bottom end of the heating chamber 4 and the heating block 51. Both ends of the heating water pipe 71 extend out of the two ends of the thawing box 1, and one end of the heating water pipe 71 is fixedly provided with a water inlet 72. Water is poured into the heating water pipe 71 from the water inlet 72. The other end of the heating water pipe 71 is connected and fixedly provided with a gooseneck pipe 73 in the middle, and the position of the heating water pipe 71 can be extended by the gooseneck pipe 73. A micro water pump 74 is connected and provided on the heating water pipe 71 between the gooseneck pipe 73 and the thawing box 1. The micro water pump 74 is centrally controlled by a control module. The micro water pump 74 is a mature prior art and is not described in detail here. The water can be heated by the water supply mechanism 7, so that the hot water is transported to the pipe or inside the pipe to thaw the frozen pipe.

[0033] The method of using the thawing device for underground water supply and drainage pipelines of the utility model is as follows: first, the deeply buried pipeline is excavated and leaked, and then the shielding plate 2 is removed through the tower buckle 11. Then the thawing box 1 is placed above the pipeline so that the concave surface at the bottom is fitted with the pipeline. In this process, the elastic cloth 9 is deformed by contact with the pipeline to avoid obstruction to the thawing process of the pipeline. At this time, the limit rod 33 can be pulled to move it to a suitable position through the U-shaped rod and the rotating rod 32, and then the limit rod 33 is inserted into the soil on the side of the pipeline, so that the position of the thawing box 1 is fixed, so that the concave surface is always fitted with the pipeline, which is convenient for subsequent thawing operations. When thawing, the motor and the heating block 51 can be controlled by the control module to work, and cold air can be sucked into the heating chamber 4 and heated by the heating block 51. At this time, the heated air contacts the pipeline through the vent 62, thereby heating the pipeline, and then realizing heating and thawing of the pipeline by hot air. When a hot towel is needed for thawing, the heating block 51 can be controlled by the control module to heat the towel before the thawing box 1 is attached to the pipe, and then the towel can be placed on the pipe for heating and thawing.

[0034] The pipe can also be opened with a tool, and then the outlet end of the heating water pipe 71 is inserted into the pipe. At this time, the length of the heating water pipe 71 can be controlled by the gooseneck 73. Pour water into the heating water pipe 71 from the water inlet 72, and control the micro pump 74 to pump water into the heating chamber 4. At this time, the heating block 51 is controlled by the control module to heat the heating water pipe 71, thereby heating the water. When the water in the heating water pipe 71 becomes hot, the micro pump 74 is continued to be controlled to work, so that hot water is supplied to the inside of the pipe for thawing. Generally, the water supply and drainage pipes are small, and the speed of hot water supply does not need to be too fast, so the water can be continuously heated and supplied to the inside of the pipe for thawing. At the same time, hot water can be directly poured onto the top of the pipe for thawing. When the pipe is thawing, a suitable thawing method can be selected according to the material and actual situation of the on-site pipe.

[0035] When thawing is finished, the tool is placed in the tool slot 10, the device is removed from the pipe, and then the shielding plate 2 is fixed to the thawing box 1 again through the tower buckle 11. At this time, the elastic cloth 9 shields the two ends of the thawing box 1 to prevent debris from entering the thawing box 1. The shielding plate 2 will shield the internal structure of the thawing box 1 to prevent blockage caused by excessive dust. The device can be transported and carried by the handle 8, which is convenient for workers to use.
