Embodiment 1

[0051] This embodiment provides a damper assembly, including a push-pull damper and a first valve, wherein, such as figure 2 As shown, the push-pull damper includes a damper body 100 and a shielding portion 102; a groove 101 is formed on the damper body 100, and the width of the groove 101 is adapted to the width of the transmission belt in the main transport channel; The shielding part 102 is arranged on the damper body 100, and the width of the shielding part 102 after unfolding is adapted to the width of the groove 101; when the push-pull damper is opened, the unfolded shielding part 102 Cooperate with the damper body 100 to cut off the wind flow path of the main transport channel; the first valve controls the opening or closing of the push-pull damper according to the received operation instruction. Wherein, the height of the groove 101 in the push-pull damper is related to the position of the push-pull damper, and its purpose is to ensure that the middle part of the damp...

Embodiment 2

[0057] This embodiment provides a method for controlling the damper assembly described in Embodiment 1, which is applied to a control system in a coal mine, such as Figure 7 shown, including the following steps:

[0058] S100: Obtain environmental monitoring data in the belt alley. A variety of sensors for monitoring environmental data are installed in the existing belt alley, specifically smoke concentration, temperature and carbon monoxide concentration, and other environmental data that can be used as a basis for judging whether a fire has occurred.

[0059] S200: If the environmental monitoring data is within the fire warning range, send a first operation command to the first valve to open the push-pull damper. For example, when the smoke concentration reaches the first threshold, the temperature reaches the second threshold, and the carbon monoxide concentration reaches the third threshold, it can be concluded that a fire has broken out in the belt alley, and measures n...

Abstract

The embodiment of the invention provides a damper component, a method and device for controlling the damper component. The damper component comprises a push-pull damper and a first valve, wherein a groove is formed in the body of the push-pull damper, and is as wide as a transmission belt in a main delivery channel, and the shielding part of the push-pull damper is as wide as the groove. When a fire disaster happens, the push-pull damper is opened, and the air-current in the main delivery channel can be effectively blocked and cannot be spread toward the lee side, so that safety of operators in a belt way of a coal mine can be improved.

Description

technical field [0001] The invention relates to the technical field of fire treatment in belt lanes of coal mines, in particular to a damper assembly and a control method and device for the damper assembly. Background technique [0002] In the prior art, the wind flow path in the coal mine belt roadway is as follows: figure 1 shown. Including the main transport channel and the return air channel, there are connecting lanes, coal walls, etc. between the main transport channel and the return air channel, and there are belts running in the main transport channel. Under normal circumstances, the connection lane is in a closed state and cannot form a wind flow path. Therefore, the wind flow path is mainly in the direction shown by the arrow in the figure, the first direction in the main transport channel, and the wind flow direction in the return air channel is opposite to that in the main transport channel. [0003] When a fire breaks out in the coal mine belt lane, the smoke...
