The sliding block 35 is slidably connected to the inner wall of the sliding groove. A connecting component 36 is arranged between the sliding block 35 and the detector body 2. The inner walls on both sides of the mounting frame 1 are respectively fixedly connected to the motor 31, and the output end of the motor 31 is fixedly connected to the winding drum 32. The surface of the winding drum 32 is wound and fixedly connected with an adjusting rope 33, and the other end of the adjusting rope 33 passes through the mounting frame 1 and is fixedly connected to the surface of the sliding block 35.

[0023] In this embodiment: when in use, the detector body 2 and the sliding block 35 can be quickly assembled through the connecting component 36. When adjusting the height, the motor 31 is turned on, and the motor 31 drives the adjustment rope 33 to reel in or unwind through the winding drum 32, so that the adjustment rope 33 can control the sliding block 35 to drive the detector body 2 to adjust the position, thereby improving the flexibility of the equipment.

[0024] Specifically, a plurality of auxiliary wheels 34 are fixedly connected to the surface of the mounting frame 1 , and the plurality of auxiliary wheels 34 are arranged at equal intervals. The plurality of auxiliary wheels 34 can support the adjustment rope 33 , thereby reducing the wear between the adjustment rope 33 and the mounting frame 1 .

[0025] Specifically, the connecting component 36 includes a connecting member 1 361 and a connecting member 2 365. The connecting member 1 361 is fixedly connected to the surface of the sliding block 35, and the connecting member 2 365 is fixedly connected to the surface of the detector body 2. The surface of the connecting member 1 361 is fixedly connected to two sliding rods 364. The surface of the sliding rod 364 is slidably connected to the limiting block 362. The surfaces of the connecting member 1 361 and the connecting member 2 365 are both provided with two grooves, and the limiting blocks 362 are respectively plugged into the inner walls of the grooves on the surfaces of the connecting member 1 361 and the connecting member 2 365.

[0026] In this embodiment: the connection can be achieved by inserting the limit block 362 into the grooves on the surface of the connecting piece 1 361 and the connecting piece 2 365. When the adjustment rope 33 cooperates with the sliding block 35 to drive the detector body 2 to move to the lowest point, the limit block 362 can be easily removed from the grooves on the surface of the connecting piece 1 361 and the connecting piece 2 365 for disassembly and maintenance.

[0031] Working principle: During the detection process, the detector body 2 can detect the ventilation performance. When it is necessary to adjust the position of the detector body 2 for detection at different heights, the motor 31 is turned on. When the motor 31 drives the winding drum 32 to rotate forward, the winding drum 32 can realize the wire-releasing operation, so that the adjusting rope 33 can control the sliding block 35 to drive the detector body 2 to move downward. When the motor 31 drives the winding drum 32 to reverse, the winding drum 32 reels the wire, and the adjusting rope 33 can control the sliding block 35 to drive the detector body 2 to move upward to realize the adjustment effect. When it is necessary to maintain and reduce the detector body 2, when the motor 31 drives the winding drum 32 to rotate forward, the winding drum 32 reels the wire, so that the slider drives the detector body 2 to move to the lowest position. The operator rotates the bidirectional screw 363, and the bidirectional screw 363 drives the limit block 362 to move, so that the limit block 362 is removed from the grooves on the surfaces of the connecting piece 1 361 and the connecting piece 2 365, and the disassembly can be completed, and the detector body 2 is removed for maintenance.
