When the plug rod 208 is completely detached from the inner surface of the baffle 205 slot, the plug rod 208 releases the fixation of the baffle 205, and the baffle 205 is rotated. When the baffle 205 is fully opened, the sliding plate 201 is moved, and the sliding plate 201 slides on the inner surface of the U-shaped frame 202.

[0034] Reference Figure 5 , Figure 6 and Figure 7As shown, specifically, the moisture-proof device 3 includes a protective shell 31, which is fixedly connected to the surface of the detector body 1, and the arc surface of the protective shell 31 is provided with two slide grooves, and the inner surfaces of the slide grooves of the two protective shells 31 are slidably connected with sliding blocks 32, and the two sliding blocks 32 are fixedly connected with a sliding frame 33 on the side away from each other, and the inner surface of the sliding frame 33 is fixedly connected with a moisture-proof pad 34, and the arc surface of the protective shell 31 is fixedly connected with two fixing rods 35, and the arc surface of the fixing rod 35 is slidably connected with an operating plate 36, and the operating plate 36 is fixedly connected to a limiting rod 37 on the side close to the protective shell 31, and the limiting rod 37 is fixedly connected to the end away from the operating plate 36 The limit block 38 is slidably connected to the surface of the sliding frame 33. When the staff needs to cover the moisture-proof pad 34 to the surface of the air hole of the detector body 1, the operating panel 36 is moved, and the operating panel 36 drives the limit rod 37 to move, and the limit rod 37 drives the limit block 38 to move. When the limit block 38 moves to a suitable position, the sliding frame 33 is moved, and the sliding frame 33 drives the moisture-proof pad 34 to move, and the sliding frame 33 drives the sliding block 32 to slide on the inner surface of the slide groove of the protective shell 31.

The sliding frame 33 is fixed to the position of the limit block 38, thereby preventing the sliding frame 33 from driving the moisture-proof pad 34 to slide, causing the moisture-proof pad 34 to separate from the surface of the air hole of the detector body 1, resulting in a decrease in the moisture-proof effect of the moisture-proof pad 34. The arc surface of the fixing rod 35 is sleeved with a spring 39, and the two ends of the spring 39 are fixedly connected to the protective shell 31 and the operating plate 36 respectively.

When the limit block 38 is completely separated from the surface of the sliding frame 33, the limit block 38 releases the fixation of the sliding frame 33 and moves the sliding frame 33. The sliding frame 33 drives the sliding block 32 to slide on the inner surface of the sliding groove of the protective shell 31, and the sliding frame 33 drives the moisture-proof pad 34 to move. When the sliding block 32 moves to the other side of the sliding groove of the protective shell 31, the moisture-proof pad 34 is separated from the surface of the air hole of the detector body 1, the operating plate 36 is released, and the rebound force of the spring 39 is released.
