Description

Technical Field

[0001] The utility model relates to the technical field of mining sensors, in particular to a waterproof installation and fixing device suitable for mining sensors. Background Art

[0002] Gas sensors are devices used to detect and measure the concentration of specific gases in the environment. When a specific gas is present in the sensor, it interacts with the material in the sensor, causing changes in the electrical or mechanical properties of the sensor material. This change can be detected and measured by the output signal of the sensor. Gas sensors are an important part of the safety monitoring system of mining projects. They can monitor parameters such as gas concentration, oxygen content, and carbon dioxide concentration in mining tunnels. They play an important role in preventing accidents, ensuring the safety of miners, and improving coal mine production efficiency. When installing gas sensors in mining tunnels, it is generally common to directly attach the sensors to the tunnel walls, but in some special cases, there will be problems with water leakage from the tunnel walls. The water can easily enter the interior along the sensor, causing sensor failure, affecting detection, and bringing hidden dangers to the safety monitoring of mining tunnels. Summary of the invention

[0003] In view of the above problems, the utility model provides a waterproof installation and fixing device suitable for mining sensors, which can effectively prevent water leakage on the tunnel wall from entering the sensor and ensure safe production. Specifically, the technical solution of the utility model is as follows.

[0004] A waterproof installation and fixing device suitable for mining sensors, comprising: a base plate, an isolation rod, a mounting plate, a top cover, a sensor and an adjusting bolt. Wherein: the base plate is arranged vertically, and is used to be fixed on the tunnel wall. The isolation rod includes a horizontal section and an inclined section that are integrally connected, one end of the horizontal section is vertically fixed on the plate surface of the base plate, the inclined section is in an inclined upward state, and the lower end of the inclined section is fixedly connected to the other end of the horizontal section. The mounting plate is arranged vertically, and the mounting plate is fixedly connected to the upper end of the inclined section. The top cover is fixed on the top of the mounting plate, and the sensor is installed and connected to the front wall surface of the mounting plate and is located below the top cover. The adjusting bolt is threadedly connected to the rear wall surface of the mounting plate, and the adjusting bolt removably connects the sensor to the mounting plate.

[0005] Furthermore, the front wall of the mounting plate has a "T"-shaped groove, and the two ends of the "T"-shaped groove are respectively located on the left and right side walls of the mounting plate. The sensor is fixed on the front wall of the vertically arranged bottom plate, and the bottom plate is movably inserted into the groove from one end of the "T"-shaped groove, and the end of the adjusting bolt abuts against the rear wall of the bottom plate, thereby fastening the bottom plate in the "T"-shaped groove.

[0006] Furthermore, a threaded tube is vertically fixed on the rear wall of the mounting plate, and the mounting plate has a through hole connected to the threaded tube. One end of the adjusting bolt passes through the threaded tube and the through hole and abuts against the rear wall of the base plate, and the adjusting bolt and the threaded tube are threadedly connected.

[0007] Furthermore, the left and right ends of the top cover extend to the outside of the left and right sides of the sensor respectively, and the top cover is in a sloped shape on both sides.

[0008] Furthermore, exhaust pipes are vertically arranged on the upper surfaces of the cover surfaces at the left and right ends of the top cover, and the cover surfaces have through holes connected to the exhaust pipes. The exhaust pipes are located outside the left and right sides of the sensor.

[0009] Furthermore, the adjusting bolt is located below the rear portion of the top cover, thereby preventing water seepage on the tunnel top wall from entering the adjusting bolt.

[0010] Furthermore, the top cover is fixed on the top surface of the mounting plate through a bracket.

[0011] Compared with the prior art, the utility model has at least achieved the following beneficial effects: when the waterproof installation and fixing device for mining sensors of the utility model uses the special structure of the isolation rod to isolate the installation plate for installing the sensor from the tunnel wall, it is avoided that the installation plate is directly attached to the tunnel wall, and the top cover is arranged above the installation plate, which can well prevent the leakage water from entering the sensor and causing its failure when there is leakage water on the tunnel wall. At the same time, the utility model also arranges a "T"-shaped groove running through the left and right on the front wall of the installation plate, so that the bottom plate can be installed and removed from the side of the installation plate by pulling and pulling, avoiding the influence of the upper top cover. The installation plate and the bottom plate are temporarily fixed by the adjusting bolt, which is convenient for the removal and installation of the sensor, convenient for later maintenance, and improves the working efficiency. In addition, by arranging the exhaust pipe on the upper surface of the cover surface at the left and right ends of the top cover, it is not only convenient to discharge the heat generated during the operation of the sensor, but also prevents the leakage water from the top from entering the sensor.

The top cover 4 is fixed to the top surface of the mounting plate 3 by a bracket 10, and the sensor 5 is mounted and connected to the front wall surface of the mounting plate 3, and the top cover 4 is inclined on both sides, and its left and right ends extend to the left and right sides of the sensor 5 respectively, so that the leakage water on the top wall of the tunnel enters the sensor 5 and causes its failure. The adjusting bolt 6 is threadedly connected to the rear wall surface of the mounting plate 3, and the adjusting bolt 6 detachably connects the sensor 5 to the mounting plate 3.

[0020] In another embodiment, continue to refer to Figure 1 and Figure 2 The front wall surface of the mounting plate 3 of the waterproof mounting and fixing device for mining sensors in the above embodiment has a "T"-shaped groove, and the two ends of the "T"-shaped groove are respectively located on the left and right side walls of the mounting plate 3. The sensor 5 is fixed on the front wall surface of the vertically arranged bottom plate 7, and the bottom plate 7 is movably inserted into the "T"-shaped groove from one end of the "T"-shaped groove. The end of the adjusting bolt 6 abuts against the rear wall surface of the bottom plate 7, thereby fastening the bottom plate 7 in the "T"-shaped groove, so that the bottom plate 7 can be installed and removed by pulling from the side of the mounting plate 3, avoiding the influence of the upper cover 4. At the same time, the mounting plate 3 and the bottom plate 7 are temporarily fixed by the adjusting bolt 6, which is convenient for the removal and installation of the sensor 5, and convenient for later maintenance, and improves the working efficiency.
