Problems solved by technology
However, the current coal mine gas drainage pump station or gas utilization system does not have a safe and reliable gas concentration control device, and usually only a single concentration monitoring device is equipped when monitoring the gas concentration, while the gas concentration requires multi-level monitoring , to ensure the stability of the surrounding environment. In addition, when monitoring the pump station, it is necessary to contact the remote control center in time to quickly respond to emergencies

Embodiment
[0032] refer to Figure 1-6 , a safety monitoring device for a coal mine gas drainage pumping station, comprising a bottom plate 1, a shell 2, a gas drainage pump, a gas pump inlet pipe, a circulating water pump and a water pump outlet pipe 3, the shell 2 is fixedly connected to the upper end of the bottom plate 1, The gas drainage pump, the gas pump inlet pipe and the circulating water pump are all connected in the casing 2. The casing 2 is provided with a circulating water tank connected with the circulating water pump. The front and rear side walls of the bottom plate 1 are rotatably connected with two mine rails. Two revolving doors are rotatably connected to the side wall of the casing 2 with the matching rolling wheel 10, and the revolving doors are correspondingly arranged on the lower sides of the two water pump outlet pipes 3 to ensure the mobile use of the gas drainage pumping station.
[0033]Wherein, the water pump outlet pipe 3 is correspondingly connected on the ...

The invention belongs to the technical field of coal mine equipment, and particularly relates to a safety monitoring device for a coal mine gas drainage pump station. The safety monitoring device comprises a bottom plate, a shell, a gas drainage pump, a gas pump water inlet pipe, a circulating water pump and two water pump water outlet pipes, the shell is fixedly connected to the upper end of thebottom plate, and the gas drainage pump, the gas pump water inlet pipe and the circulating water pump are all connected into the shell. The two water pump water outlet pipes are correspondingly connected to the outer side wall of the shell, the input ends of the two water pump water outlet pipes are connected with the output end of the circulating water pump, the two water pump water outlet pipesare each in an L shape and are arranged back to back, and the ends, away from the shell, of the two water pump water outlet pipes are connected with a first pipeline and a second pipeline correspondingly. The safety monitoring device has the advantages that the gas concentration around the gas drainage pump station can be monitored in real time, once the monitored numerical value is wrong comparedwith the numerical values set by a low-concentration sensor and a high-concentration sensor, an alarm device can be triggered, and surrounding workers can be warned.
Description
technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a safety monitoring device for a coal mine gas drainage pumping station. Background technique [0002] In the process of coal mining, due to the large amount of gas contained in the coal seam, explosion disasters are prone to occur, which brings great danger to mining. In order to manage gas disasters, people have invented a mining mobile gas drainage pumping station, which can directly drain gas directly into the site, and transport the gas to the ground through pipelines for use, turning harm into treasure. [0003] However, the safety regulations of coal mines stipulate: "The concentration of gas in mines where gas is drained shall not be lower than 30%", otherwise it may cause an explosion. However, there is no safe and reliable gas concentration control device in the current coal mine gas drainage pumping station or gas utilization system, and only a single conc...
