Problems solved by technology

[0002] At present, dust accidents, especially dust explosions, are a major danger faced by mines. Some mines lack regular detection of dust concentration in the well, which may easily cause excessive dust concentration and increase the possibility of dust explosion. Some existing detection devices , the structure is relatively complex, which is not conducive to large-scale use in mines

Embodiment 1

[0018] like figure 1 , figure 2 As shown, the dust concentration detection mechanism includes a connecting rod 6 installed on the inner wall of the mine. The connecting rod 6 is an L-shaped structure, and also includes a dust cover 1 and a cloth cover 4. The sensor 12 and the dustproof cover 1 are installed on the connecting rod 6 below the dust concentration sensor 12, the upper opening of the cloth cover 4 is connected to the cover edge of the dustproof cover 1, and the lower opening of the cloth cover 4 is provided with an elastic mouth 5, The angle between the upper opening of the cloth cover 4 and the lower opening of the cloth cover 4 is a right angle, and a mounting hole is provided on the cloth cover 4, and a cloth curtain 2 for sealing the mounting hole is arranged on the mounting device, and the cloth curtain 2 One side is fixed on the cloth cover 4 on the edge of the corresponding installation hole, and the other side is in a movable and sealed connection with the...

Embodiment 2

[0027] On the basis of the first embodiment, the rubber layer is changed to 1.5 mm; the connecting piece 3 is changed to Velcro; the vertical distance between the dust cover 1 and the dust concentration sensor 12 is changed to 25 cm.

[0028] Others are the same as embodiment one.

Embodiment 3

[0030] On the basis of the first embodiment, the rubber layer is changed to 2 mm; the connecting piece 3 is changed to a snap button; the vertical distance between the dust cover 1 and the dust concentration sensor 12 is changed to 30 cm.

[0031] Others are the same as embodiment one.

Abstract

The invention relates to a dust concentration detecting mechanism, and belongs to the technical field of dustproof equipment. The dust concentration detecting mechanism comprises a connecting rod mounted on the inner wall of a mine, and meanwhile, further comprises a dustproof cover and a cloth sleeve. A dust concentration sensor is mounted at the top of the connecting rod. The dustproof cover ismounted at the position, below the dust concentration sensor, of the connecting rod. An upper opening of the cloth sleeve is connected to the cover edge of the dustproof cover. A mounting hole is formed in the cloth sleeve. The mounting hole is provided with a cloth curtain used for sealing the mounting hole. One side of the cloth curtain is fixed to the cloth sleeve corresponding to the edge of the mounting hole. The other sides of the cloth curtain are connected with the cloth sleeve corresponding to the edge of the mounting hole in movable and sealed modes through connecting pieces. A control box is mounted at the position, corresponding to the cloth curtain, of the connecting rod in the cloth sleeve. A storage battery, a signal transmission module, a timer and a PLC are mounted in thecontrol box. The dust concentration sensor, the signal transmission module, the storage battery and the timer are connected to the PLC. The dust concentration detecting mechanism improves the safety and reduces the occurrence of dust accidents.

Description

technical field [0001] The invention relates to a dust concentration detection mechanism, which belongs to the technical field of dust-proof equipment. Background technique [0002] At present, dust accidents, especially dust explosions, are a major danger faced by mines. Some mines lack regular detection of dust concentration in the well, which may easily cause excessive dust concentration and increase the possibility of dust explosion. Some existing detection devices , the structure is relatively complex, which is not conducive to the large-area use in mines. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a dust concentration detection mechanism, which has a simple structure, improves safety, reduces dust accidents, and has a long service life. [0004] The dust concentration detection mechanism of the present invention includes a connecting rod installed on ...
