Description

Technical Field

[0001] The utility model relates to the technical field of underground mine earthquake monitoring equipment, in particular to a safety protection box for underground mine earthquake monitoring equipment. Background Art

[0002] Channel wave seismic exploration in underground coal mines is a geophysical method that uses the propagation characteristics of guided waves to detect geological anomalies in coal seams at the working face. In the 1980s, we were the first in China to introduce German channel wave exploration equipment and technology. We have carried out underground channel wave exploration in more than 70 mines in China and accumulated rich experience.

[0003] For example, the authorization announcement number "CN219802771U" is named a mine monitoring equipment protection box. Although the inverted V-shaped top cover, the box body, the top and side surfaces of the second box body, and the heat dissipation holes staggered on the heat dissipation base improve the waterproof, dustproof and heat dissipation functions of the protection box, the existing mine monitoring equipment protection box is used to install mine monitoring equipment. For the base monitoring equipment, the mine needs to be set up deep underground. The underground environment is complex and changeable and there is a risk of collapse and falling rocks. Common mine earthquake monitoring equipment has more sophisticated circuits and electronic parts. Therefore, when a collapse occurs below the mine or large rocks fall and hit the equipment protection box, the huge impact force and pressure will directly damage the outer shell of the protection box, thereby causing damage to the electronic parts and circuits inside the equipment protection box, resulting in the mine monitoring equipment protection box. The protection effect is not good enough.

[0004] At the same time, the existing mine monitoring equipment protection box needs to be placed in an underground mine together with the internal earthquake monitoring equipment when protecting the earthquake monitoring equipment. Underground mines often have groundwater or dark holes. The internal water is deep and easily corrodes the outer wall of the protection box. At the same time, too much water will make it impossible to lay the connecting circuit of the earthquake monitoring equipment in the water. Therefore, the earthquake monitoring equipment often suffers from power outages and poor power contact, which greatly affects the use effect of the mine monitoring equipment protection box. Utility Model Content

[0005] The utility model aims to solve the problem of poor protection effect and poor use effect of the protection box of mine monitoring equipment, and proposes a safety protection box for underground mine earthquake monitoring equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safety protection box for earthquake monitoring equipment in a mine, comprising a base, a placing platform and a protection box body, wherein the placing platform is fixedly connected to the top of the base, and a mine box body collapse protection structure is arranged above the placing platform, and the mine box body collapse protection structure comprises vertical poles, horizontal plates and a top cover, and a plurality of the vertical poles are fixedly installed above the placing platform, and two horizontal plates are slidably connected to the outer sides of the plurality of vertical poles, and a top cover is fixedly installed on the inner sides of the two horizontal plates, and a reinforcing keel is fixedly connected to the inner side of the top cover, and a limiting ball is fixedly installed on the top ends of the plurality of vertical poles, and a buffer spring is movably sleeved on the outer sides of the plurality of vertical poles.

[0007] Preferably, the top ends of the plurality of buffer springs are movably connected to the bottom of the transverse plate, the bottom ends of the plurality of buffer springs are movably connected to the top of the placement table, and the protective box is fixedly installed above the placement table.

[0008] Preferably, the main body of the earthquake monitoring device is fixedly installed on the inner side of the protection box, and a protection door is movably hinged to the front end of the protection box through a hinge, and the inner side of the protection door is arranged opposite to the front end driven by the main body of the earthquake monitoring device.

[0009] Preferably, a ventilation reinforcement structure for earthquake monitoring equipment is provided inside the protection box;

[0010] The ventilation reinforcement structure of the earthquake monitoring equipment includes a support rod, an air inlet and an air outlet;

[0011] The air inlet is fixedly opened on one side of the outer wall of the protective box body, a fan is fixedly installed inside the air inlet, the two support rods are fixedly installed inside the protective box body, a protective layer is fixedly connected above the two support rods, and the exhaust hole is fixedly opened at the other end of the outer wall of the protective box body.

[0012] Preferably, the inner sides of the two support rods are movably connected to the two sides of the main body of the earthquake monitoring device, and the bottom of the protective layer is movably connected to the top of the main body of the earthquake monitoring device.

[0013] Preferably, a backup power supply and a waterproof structure for earthquake monitoring equipment are provided on the inner side of the base;

[0016] The utility model proposes a safety protection box for underground mine earthquake monitoring equipment, which has the beneficial effect that when the safety protection box for underground mine earthquake monitoring equipment is hit by collapsed rocks, the fallen soil and rocks will first hit the top of the top cover, and then the top cover will push the cross plate downward, and the cross plate will squeeze multiple buffer springs to contract. The buffer springs are used in conjunction with a strong top cover to reduce the situation in which collapsed rocks in the mine damage the protection box body, thereby improving the protection effect of the safety protection box for underground mine earthquake monitoring equipment.

[0017] The waterproof layer is made by applying an impermeable and highly waterproof polyurethane waterproof coating on a stainless steel metal shell. In this way, the waterproof layer is wrapped around the outside of the base to reduce water accumulation in the mine to rust the base. The backup power supply can be a high-power battery that is fully charged in advance on the ground.
