[0020] During operation, the connecting pipe 4 will be wrapped by the wrapping ring 501 and the fastening bolt 502, and then the wrapping ring 501 will be installed on the housing assembly 1 by the installation bolt 504. The second spring 506 can continuously push up the connecting ear 503, so that the wrapping ring 501 pushes the connecting pipe 4, thereby increasing the stability of the connection between the connecting pipe 4 and the safety valve body 3. At the same time, the above method can also increase the connection range of the connecting pipe 4 and the equipment, increase the force area, so that the equipment can ensure a stable connection even when it is subjected to a large gravity.

[0021] like Figure 1 As shown, the housing assembly 1 includes a protective housing 101, a heat-insulating layer 102 and a hinge 103, wherein the heat-insulating layer 102 is installed inside the protective housing 101, and the hinge 103 is installed on the left side of the protective housing 101;

[0022] The protective shell 101 wraps the safety valve body 3 through the rotating structure formed between the protective shell 101 and the hinge 103 .

[0023] like Figure 1 and Figure 2 As shown, a dehumidification component 2 is installed at the rear end of the interior of the housing component 1 , and a safety valve body 3 is installed at the middle part of the interior of the housing component 1 .

[0024] like Figure 2As shown, the dehumidification component 2 includes a dehumidification box 201, a mesh plate 202 and absorbent cotton 206, and the mesh plate 202 is installed at the front end of the dehumidification box 201, and the absorbent cotton 206 is installed inside the dehumidification box 201. The dehumidification component 2 also includes a lower plate 203, a first spring 204 and a drain port 205, and the lower end of the absorbent cotton 206 is provided with the lower plate 203, the lower end of the lower plate 203 is connected to the first spring 204, and the rear end of the lower plate 203 is provided with the drain port 205, the dehumidification component 2 also includes a lower pressure plate 207 and a multi-section electric telescopic rod 208, and the lower pressure plate 207 is provided above the absorbent cotton 206, and the multi-section electric telescopic rod 208 is installed above the lower pressure plate 207;

[0025] During the working process, the insulation layer 102 is used to keep the device warm, and the absorbent cotton 206 is used to absorb water, thereby ensuring the working environment inside the device and maintaining a suitable environment when the device is working. At the same time, the absorbent cotton 206 can be pressed by the lower pressure plate 207 to discharge the water inside the absorbent cotton 206 from the drain port 205, so that the device can continue to dry.

[0026] During use, the safety valve body 3 and the connecting pipe 4 are first connected together by bolts, and then the protective shell 101 is used to wrap the safety valve body 3 through the rotating structure formed between the protective shell 101 and the hinge 103, and then the wrapping ring 501 is tightened by the fastening bolt 502, so that the wrapping ring 501 wraps the connecting pipe 4, and then the rotating head 505 is rotated to make the threaded connection between the mounting bolt 504 and the protective shell 101 push the connecting ear 503 upward, thereby assisting the connection between the safety valve body 3 and the connecting pipe 4, and relying on the elastic structure formed between the connecting ear 503 and the second spring 506 and the rotating head 505, the connecting ear 503 is subjected to a continuous upward force, thereby ensuring the stable connection between the safety valve body 3 and the connecting pipe 4. During the operation of the equipment, The insulation layer 102 insulates the interior of the equipment, thereby preventing the safety valve body 3 from being frozen in winter. At the same time, the absorbent cotton 206 can also dehumidify the interior of the equipment from one side of the mesh plate 202, and dry the interior of the equipment, thereby preventing moisture from damaging the safety valve body 3. After dehumidification has been carried out for a period of time, the multi-section electric telescopic rod 208 is opened to push the lower pressure plate 207 downward, so that the lower pressure plate 207 compresses the absorbent cotton 206. The absorbent cotton 206 is under pressure and will squeeze the lower plate 203 downward, thereby exposing the drain port 205. In this way, the squeezed water can be discharged to the outside of the equipment. When the lower pressure plate 207 is released, the lower plate 203 will move upward again by relying on the elasticity of the first spring 204, so that the lower plate 203 blocks the drain port 205, preventing external moisture from entering the equipment.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
