Progressive coal mine ventilation apparatus with alarming function

Abstract

The invention discloses a progressive coal mine ventilation apparatus with an alarming function. The progressive coal mine ventilation apparatus comprises a shell, a single chip microprocessor and methane sensors, wherein the shell is provided with an air duct, a guide blade is installed below a first retainer net, a guide groove is connected with an air groove, a water passage is installed insidethe shell, a linkage blade is fixedly arranged inside water outlet cylinders, each water outlet cylinder is fixedly provided with a water sprinkling block, each water sprinkling block is provided with water outlet holes, the lower end of the shell is provided with the single chip microprocessor, the single chip microprocessor is connected with a buzzer, the single chip microprocessor is connectedwith the methane sensors, and the methane sensors are installed on the inner wall of the air groove. The progressive coal mine ventilation apparatus with the alarming function adopts a novel structure design to design a structure with the ventilation function, so that the problem that dust is easy to accumulate inside a traditional apparatus can be solved; and meanwhile, by designing a structurewith a uniformly sprinkling function, the problem that a great amount of flying dust is produced when the traditional apparatus works can be solved.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a progressive coal mine ventilation device with an alarm function. Background technique [0002] The main task of mine ventilation is to supply enough fresh air underground to meet the needs of underground workers for oxygen, adjust the underground climate, dilute harmful gases and dust underground, and ensure safe production underground. [0003] Toxic and harmful gases are continuously produced underground during the mining process of coal mines. In order to ensure the normal operation of mining, underground ventilation is essential. Coal mine ventilation devices can solve this problem very well, but existing coal mine ventilation devices have problems during operation. The disadvantages of easy dust accumulation inside the traditional device and large dust when the traditional device is working. In view of the above problems, it is urgent to carry out innovative...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a progressive coal mine ventilation device with an alarm function, so as to solve the problems in the above-mentioned background technology that the interior of the traditional device is easy to accumulate dust and the dust is relatively large when the traditional device is working.
