Description

Technical Field

[0001] This utility model relates to the field of gas detection probe technology, specifically an explosion-proof gas pressure detection probe. Background Technology

[0002] In coal mines, the gas pressure of the coal seam must be tested to prevent excessive gas pressure from causing dangerous accidents inside the coal seam.

[0003] For example, the Chinese authorized patent with announcement number CN221720227U, entitled "(A detection probe and gas pressure detection device)," includes: ear plates, a winding roller on the outer wall between the two ear plates, and limit plates fixedly connected to the side walls at both ends of the winding roller. The beneficial effects are: pulling the pull block causes the baffle on the outside of the adjusting rod to compress the spring, disengaging the positioning block and the toothed block; simultaneously, when the positioning hole protrudes from the fixing frame, it is fixed by inserting a pin, so that the outer wall of the pin contacts the outer wall of the fixing frame to fix the adjusting rod; then, shaking the handle realizes the winding and unwinding of the detection hose; after completion, the pin is pulled out, the positioning block springs back and engages with the toothed block, preventing the shaft from rotating. The detection probe increases the length of the detection hose and facilitates its winding and unwinding, improving its practicality.

[0004] However, existing pressure gas detection probes are prone to explosion due to external environmental factors during use, and the resulting debris can cause personal injury. Therefore, they do not meet current requirements. To address this, we have proposed an explosion-proof pressure gas detection probe. Utility Model Content

[0007] Also includes:

[0008] An inner cavity is installed inside the outer cover and base plate of the detection probe. The detection probe body is located at the middle position of the upper surface of the base plate.

[0011] Preferably, a protective sleeve is provided around the outer wall of the detection probe cover, and the protective sleeve is connected to the sliding sleeve of the detection probe cover.

[0012] Preferably, the outer wall of the connecting rod is provided with a hexagonal nut.

[0013] Preferably, the lower end of the connecting rod is provided with a bolt rod, and the lower end face of the bolt rod is provided with an electrode plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of mounting holes, inner cavity, first explosion-proof protective metal mesh cover, first buckle block, second explosion-proof protective metal mesh cover and second buckle block, provides a first explosion-proof protective metal mesh cover 107 and a second explosion-proof protective metal mesh cover 108 on the outside of the detection probe body 200.

These are installed inside the mounting hole 10502 of the base plate 105 by the first snap-fit ​​block 10701 and the second snap-fit ​​block 10801. The detection probe outer cover 100 is then threaded to the base plate 105 by the threaded inner wall 10501, thus maximizing the explosion-proof protection structure for the detection probe body 200.

[0028] Example 2
