Intrinsic safety type water shortage alarm device for mining

Abstract

The invention discloses an intrinsic safety type water shortage alarm device for mining. The intrinsic safety type water shortage alarm device is composed of an intrinsic safety type mining controller, a fastening embedding plate, body fixed column casings, a clamping groove, a performance indicator plate, an alarm machine body, a right pedestal fixed lug, a body pedestal, a left pedestal fixed lug, and a controller groove. The two body fixed column casings are arranged and fixed at the left side and the right side of the fastening embedding plate vertically and respectively; and the fasteningembedding plate is fixed on the alarm machine body. The an intrinsic safety type mining controller is provided with a wire jack extension board, a controller body, a wire fastening groove, and a conduction PC board. With the digital technology, the motion is reliable, the anti-interference capability is strong, and the response time is short; the high-brightness LED displaying is realized; the professional voice circuit is provided; high-fidelity outputting and complete electronic detection are realized; no mechanical equipment like a floater is needed; C type relay outputting is realized; the structure is simple and thus the device is easy to maintain and repair; and the device has acousto-optic displaying and signal blocking functions and has advantages of high motion sensitivity and reliable performances.

Description

technical field [0001] The invention relates to an intrinsically safe water shortage alarm for mines, belonging to the technical field of water shortage alarms. Background technique [0002] Intrinsically safe alarm for mining is mainly used to remind the supply of cooling water for water-cooled motors. The device has the characteristics of simple structure, reliable operation, strong anti-interference, convenient maintenance, low failure rate and good interchangeability, etc., and is effective Improve working conditions, improve transportation efficiency, and also lay a good foundation for transportation automation. [0003] The water shortage alarm disclosed in the prior art cannot realize the intrinsically safe structure used in mines, and has weak anti-interference ability, cannot use digital technology, and cannot achieve efficient and convenient detection and alarm effects. Contents of the invention [0004] In view of the deficiencies in the existing technology, th...
