[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example 1:

[0020] Reference Figs. 1-3 A mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation includes a communication monitoring substation body 1, and further includes: a mounting plate 2, the communication monitoring substation body 1 being fixedly installed on the side wall of a designated roadway in the mine via the mounting plate 2; a protective plate 202, rotatably connected to the upper end of the mounting plate 2 via a rotating shaft 201, and located above the communication monitoring substation body 1; an arc-shaped sleeve 3, symmetrically fixedly connected to the mounting plate 2, and located on both sides of the communication monitoring substation body 1; an arc-shaped rod 301, slidably connected inside the arc-shaped sleeve 3, with one end of the arc-shaped rod 301 extending out of the arc-shaped sleeve 3 and fixedly connected to the protective plate 202; and a tension spring 302, installed inside the arc-shaped sleeve 3, with both ends fixedly connected to the arc-shaped sleeve 3 and the arc-shaped rod 301 respectively.

[0021] When it is necessary to install this mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation underground to collect various environmental parameters such as gas concentration, temperature, humidity, and equipment operating status information in real time, the installation personnel first transport the mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation to the designated location underground. Then, the installation personnel first fix the mounting plate 2 to the side wall of the roadway with expansion bolts. Then, the communication monitoring substation body 1 is fixed to the side of the mounting plate 2 with protective plate 202 with fixing bolts. Finally, the communication monitoring substation body 1 is electrically connected to various underground equipment, and the communication monitoring substation body 1 is electrically connected to the ground monitoring center through the existing underground power lines. After the installation is completed, the mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation can be debugged. After the debugging is completed, it can be put into use.

[0022] When a rock falls from the well and hits the communication monitoring substation 1, it is blocked by the protective plate 202. When the rock hits the protective plate 202, the protective plate 202, under the downward impact force of the rock, compresses the tension spring 302 through the arc rod 301, thus buffering and dissipating the impact force generated by the falling rock. Then the protective plate 202 tilts, and the rock rolls down the inclined surface of the protective plate 202 to the ground. After the rock leaves the protective plate 202, the protective plate 202 is then under the tension of the tension spring 302. Rotating from bottom to top to the initial position, the installation plate 2, rotating shaft 201, protective plate 202, arc sleeve 3, arc rod 301, and tension spring 302 can buffer and guide rocks falling onto the communication monitoring substation body 1, preventing them from falling directly onto the body and causing damage, short circuits, and fires. This greatly improves the reliability and safety of the mine explosion-proof and intrinsically safe power line carrier communication monitoring substation in complex and dangerous underground environments.

[0023] Example 2:

[0024] Reference Figs. 1-3 The mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation is basically the same as that in Embodiment 1, but further includes two sets of buffer springs 2021 and buffer plates 2022. The buffer plates 2022 are set above the protective plate 202, and the two sets of buffer springs 2021 are symmetrically arranged between the protective plate 202 and the buffer plates 2022. The two ends of the buffer springs 2021 are fixedly connected to the protective plate 202 and the buffer plates 2022 respectively. Through the arrangement of the buffer plates 2022 and the buffer springs 2021, when a rock falls onto the protective plate 202, the rock can be buffered multiple times, thereby reducing the impact force of the rock on the protective plate 202 and effectively improving the buffering and stress relief effect on the rock.

[0025] A push-button electronic counter 2023 is fixedly installed on the protective plate 202. The detection end of the push-button electronic counter 2023 is in contact with the lower surface of the buffer plate 2022. The push-button electronic counter 2023 is coupled and connected to the communication module inside the communication monitoring substation body 1.

[0026] When rocks fall onto the buffer plate 2022, the buffer plate 2022 overcomes the elasticity of the buffer spring 2021 under the impact of the rocks and presses the push-type electronic counter 2023. The push-type electronic counter 2023 then counts, thereby monitoring the rockfall situation around the communication monitoring substation. At the same time, the data monitored by the push-type electronic counter 2023 is also transmitted to the ground monitoring center through the communication monitoring substation body 1. Then, the staff at the ground monitoring center can analyze and judge the number and frequency of falling rocks to assess the danger situation in the area. When the danger reaches a certain level, the ground staff can dispatch installation personnel to dismantle the communication monitoring substation and install it in another location to ensure the safety of the communication monitoring substation.

[0027] Example 3:

[0028] Reference Figs. 1-3 The mine-use explosion-proof and intrinsically safe power line carrier communication monitoring substation is basically the same as that in Example 2, but with a further improvement: a water storage chamber is provided inside the mounting plate 2, and a spray pipe 305 is fixedly connected to the upper end of the protective plate 202 near the mounting plate 2. Multiple nozzles are equidistantly connected to the spray pipe 305. A piston is provided at one end of the arc-shaped rod 301 located inside the arc-shaped sleeve 3. The arc-shaped sleeve 3 has an inlet and an outlet, and a one-way valve is provided in both the inlet and outlet of the arc-shaped sleeve 3. The inlet of the arc-shaped sleeve 3 is connected to the water storage chamber through a first water pipe 303, and the outlet of the arc-shaped sleeve 3 is connected to the inlet of the spray pipe 305 through a second water pipe 304. When there is rock in the mine... When a rock falls onto the protective plate 202, the impact will cause dust to fly up. Due to the impact force of the rock, the curved rod 301 will overcome the elastic force of the tension spring 302 and move into the curved sleeve 3. Therefore, the water in the water storage chamber that was previously drawn in through the first water pipe 303 will be transported into the spray pipe 305 through the second water pipe 304. Then, the nozzle of the spray pipe 305 will spray water mist into the air to suppress the dust, effectively reducing the dust content in the air and reducing the dust adhering to the surface of the communication monitoring substation body 1, thus effectively ensuring the heat dissipation effect of the communication monitoring substation body 1 itself.

[0029] like Fig. 2As shown, a semiconductor cooling chip 204 is fixedly installed in the water storage cavity of the mounting plate 2. The communication monitoring substation body 1 and the mounting plate 2 are tightly attached by fixing bolts. With the setting of the semiconductor cooling chip 204, the water in the water storage cavity can be cooled down, which facilitates the heat dissipation and cooling effect of the communication monitoring substation body 1 and effectively improves the service life of the communication monitoring substation body 1.

[0030] like Fig. 2 As shown, the mounting plate 2 is provided with multiple heat exchange fins 203 on the side near the communication monitoring substation body 1. The two ends of the heat exchange fins 203 extend into the water storage chamber and the communication monitoring substation body 1, respectively. Through the arrangement of the heat exchange fins 203, when the electrical components inside the communication monitoring substation body 1 generate heat during operation, the heat exchange fins 203 can quickly conduct heat out and dissipate heat, thereby further improving the heat dissipation effect of the communication monitoring substation body 1.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
