Each telescopic base 301 has a telescopic rod 302 on the side near the double-headed vertical pipe 204. The telescopic rods 302 are connected to the clamping plate 303 through a fixing plate. The telescopic rods 302 are used to move the clamping plate 303 back and forth. Each telescopic rod 302 is provided with a clamping plate 303 at one end near the double-headed vertical tube 204. The clamping plate 303 is used to clamp the clamp 304. The clamping end of the clamping plate 303 is provided with a clamp 304. The clamp 304 consists of a circle composed of two arc-shaped collars. The joint of each arc-shaped collar is fixed by a pad and bolts, thereby clamping the double-headed vertical tube 204 fitted inside the circle. The clamp 304 is used to stabilize the double-headed vertical tube 204. The clamp 304 clamps the double-headed vertical tube 204. Both ends of the arc-shaped clamp near the telescopic rod 302 are provided with a clamp 304 to prevent the double-headed vertical tube 204 from shaking.
[0029] Its effects are as follows: the clamp 304 is used to prevent the double-headed vertical pipe 204 from shaking, and the telescopic rod 302 is used to move the clamp 303 back and forth, thereby controlling the back and forth adjustment of the clamp 303 and facilitating the clamping and fixing of the double-headed vertical pipe 204.
[0030] like Figure 2 , 3 As shown in Figure 4: An observation window 407 is provided on the top of the sealing plate 401, and the observation window 407 and the sealing plate 401 can be fixed together by adhesive.

[0034] Working principle: The buried switch box 100 is isolated into two areas by the sealing frame 400 and the sealing plate 401. When a leak occurs at the connection mechanism 101, its diffusion range can be reduced, so that the leaked gas concentrates and floats upward. Then, the height of the detection probe 409 is increased by the extension pipe 408, so that the leak detector 406 can quickly detect whether a leak has occurred. When a leak occurs, the main switch can be cut off in time, thereby improving the safety performance of the device.
[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
