Abstract

The present invention is applicable to the technical field of mine power supply and distribution, and provides a mine power supply and distribution device with a moisture-proof function, including: a heat dissipation component installed on the side of the power supply distribution box; a moisture-proof box installed on the side of the power supply distribution box, and a dust and moisture-proof component is installed inside the moisture-proof box. When the mine power supply and distribution device with the moisture-proof function is in use, at the same time, the heat dissipation component can perform air cooling and heat dissipation on the inside of the power supply distribution box, avoiding the heat accumulation inside the power supply distribution box caused by poor air circulation underground in the mine, accelerating the air circulation speed, and reducing the operating temperature. At the same time, due to more dust underground in the mine and greater moisture in the air, when the heat dissipation component is in use, the dust and moisture-proof component filters the impurities in the air, avoiding short circuits in the circuit caused by impurities entering the inside of the power supply distribution box, and at the same time, it can also absorb the moisture in the air to ensure that the gas entering the inside of the power supply distribution box is dry gas, preventing moisture absorption.

Description

Technical Field

[0001] The present invention belongs to the technical field of mine power supply and distribution, and particularly relates to a mine power supply and distribution device with a moisture-proof function. Background Technique

[0002] Electricity is the main energy source for the production of coal mining enterprises. The reliability of the coal mine power supply system is the core to ensure the safe production of coal mining enterprises, and it is of great significance for improving product quality, economic benefits and ensuring safe production. In order to ensure the safe production of the entire coal mine, a reasonable and reliable underground power supply system is particularly important. Previously, the main circuits and electrical equipment of the coal mine power supply system used relay protection equipment to complete power supply protection. With the need for coal mine safety production, traditional relay protection equipment can no longer fully meet the needs of the coal mine power supply system. At present, all coal mine power supply systems use new microcomputer protection devices. Here, we will conduct a simple analysis of the microcomputer protection of the coal mine power supply system.

[0003] During the actual use of existing mine power supply distribution boxes, due to the heavy moisture in the mine and extremely poor air circulation, it is very easy for the heat inside the power supply distribution box to accumulate, which is prone to spontaneous combustion. If only methods such as adding fans to the power supply distribution box are used for heat dissipation, it is easy to blow the air containing heavy moisture in the mine into the power supply distribution box. The water in the air will not only corrode the internal circuit, but also easily cause the circuit to be affected by moisture, resulting in short circuits and other situations, with relatively high potential safety hazards.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

At the same time, due to more dust and greater moisture in the air below the mine, when the heat dissipation component 4 is in use, the dust and moisture-proof component 6 filters the impurities in the air, preventing the impurities from entering the inside of the power supply box 3 and causing a short circuit. At the same time, it can also absorb the moisture in the air to ensure that the gas entering the inside of the power supply box 3 is dry gas, preventing moisture absorption.

[0075] A clamping component is installed on the mounting plate 64 for restricting the position of the mounting plate 64.

[0076] During use, the mounting plate 64 is inserted into the mounting opening 63. When the inclined surface of the first toothed plate 624 comes into contact with the edge part of the mounting opening 63, the first toothed plate 624 will be pushed into the first groove 621. Then the first toothed plate 624 will drive the first gear 628 to rotate. Further, all the second gears 629 are controlled to rotate through the transmission belt 630. Then, under the push of the second gear 629, the toothed plate 626 will move, so that the stop rod 627 moves onto the moisture absorption plate 67 to restrict the position of the moisture absorption plate 67 and prevent it from falling off.

[0083] When the first tooth plate 624 enters the installation opening 63, the second tooth plate 634 will disengage from the installation opening 63. Then, under the action of the second spring 633, the second tooth plate 634 will be ejected, and the mounting plate 64 is fixed by the cooperation between the second tooth plate 634 and the side wall of the moisture-proof box 5. When the mounting plate 64 needs to be removed, just hold the first handle 640 and lift the second handle 641 upward. Then the second handle 641 will drive the pulling post 639 to move upward, and the pulling rope 636 is used to drive the third gear 635 to rotate.

At the same time, it can also absorb the moisture in the air to ensure that the gas entering the inside of the power supply distribution box 3 is dry gas, preventing moisture.
