Description

Protective cover of mining pressure transmitting sensor Technical Field The utility model relates to the technical field of mining pressure transmitting sensors, in particular to a protective cover of a mining pressure transmitting sensor. Background The mining pressure transmitting sensor is pressure monitoring equipment used in severe environments such as underground coal mines and is widely applied to scenes such as fluid pressure detection, hydraulic support systems and pump station systems in the mines, and a protective cover of the mining pressure transmitting sensor is an important part for protecting the sensor from the severe environments of the mines, and is arranged into a hollow cylindrical structure, and the installation between a sensor connector and a sensor output interface is completed through screw mechanisms at the upper end and the lower end of the cylindrical structure; However, the protection cover in the existing market is only of a penetrating hollow structure, when the pressure sensitive element and the amplifying circuit are placed, in order to ensure that the pressure sensitive element and the amplifying circuit are stably clamped inside, the pressure sensitive element and the amplifying circuit are generally clamped with the inside of the protection cover through friction force, so that the follow-up disassembly and maintenance of the pressure sensitive element and the amplifying circuit inside are caused, a worker is required to manually scratch out the pressure sensitive element and the amplifying circuit inside the protection cover, the whole process is troublesome to operate, the pressure sensitive element and the amplifying circuit are damaged manually, and the disassembly cost of the pressure sensitive element and the amplifying circuit is increased. Disclosure of utility model The utility model aims to provide a protective cover of a mining pressure transmitting sensor, which aims to solve the problem that the protective cover in the current market provided by the background technology is not provided with a corresponding auxiliary mounting structure, so that the subsequent mounting and dismounting of a pressure sensitive element and an amplifying circuit are inconvenient. The protective cover of the mining pressure transmitter sensor comprises a cover body, wherein the cover body is in a hollow cylindrical structure, threaded grooves are formed in the inner walls of the upper top end and the lower top end of the cover body, the threaded grooves at the top end of the cover body are in threaded connection with a sensor connector, and the threaded grooves at the top end of the cover body are in threaded connection with a sensor output interface; The inside of the cover body is provided with an auxiliary mounting structure for carrying out auxiliary mounting work on the pressure sensitive element and the amplifying circuit, the auxiliary mounting structure moves up and down in the inside of the cover body and drives the pressure sensitive element and the amplifying circuit to move upwards, so that the purpose of facilitating the mounting and dismounting of workers is achieved.
