Embodiment Construction

[0037] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, and are not exhaustive of all the embodiments. And in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.

[0038] Embodiments of the present invention provide a ventilation device for coal mines. Such as Figures 1 to 7 As shown, the ventilation device used in coal mines includes a ventilation pipe 1, a regulating assembly and an actuating assembly. Wherein, the ventilation pipe 1 is cylindrical, and its two ends in the axial direction are respectively connected to the ventilation pipes of the coal mine for air circulation. The adjusting component is arranged in...

Abstract

The invention provides a ventilation device for a coal mine. The device comprises a cylindrical ventilation pipe, an adjusting assembly which is arranged in an inner cavity of the ventilation pipe and is used for adjusting a through-flow area of the ventilation pipe, and an actuating assembly which is used for actuating the adjusting assembly to operate so as to adjust the through-flow area of the ventilation pipe. By arranging the adjusting assembly in the ventilation pipe, the through-flow area of the ventilation pipe can be controllably changed, so that the air volume of air flowing in the inner cavity of the ventilation pipe can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and in particular relates to a ventilation device for coal mines. Background technique [0002] Coal mines mainly refer to coal-rich mining areas. Generally, it is necessary to dig underground roadways to mine coal mines. This is an underground coal mine. There are also coal mines that are directly stripped of the surface soil layer. This is an open-pit coal mine. In the process of mining coal mines, ventilation devices need to be used, which is conducive to maintaining the flow of gas in the inner space of coal mines, but the existing coal mine ventilation devices still have the following problems; [0003] After the coal mine ventilation device is fixedly installed, it cannot effectively adjust the air volume of the internal air flow properly. [0004] Therefore, it is necessary to design a ventilation device for coal mines that can regulate the air volume, so as to solve the above-mentione...
