Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to a wind and water linkage booster pump device. Background Art

[0002] In underground mining, in order for workers to reach the mining area, a horizontal or inclined passage leading to the ground is dug in the rock mass or ore layer. This passage is usually called a tunnel. Tracks are laid in the tunnel to directly connect the working surface and the outside of the mine for workers to enter and exit, and for the transportation of production materials and minerals. The tunnel is also a passage for ventilation, drainage, power supply, etc. At present, gas explosion and combustion in coal mines are the most serious and difficult to prevent malignant accidents in coal mines. Each accident causes significant losses to the workers' lives and property, ranging from dozens of deaths to hundreds of deaths; the losses caused by each accident range from millions of yuan to tens of millions or even hundreds of millions of yuan. The traditional method of preventing underground gas explosions is mainly to inject fresh air into the mine to control the gas content in the air in the tunnel below the critical concentration of combustion and explosion.

[0003] Hydraulic props are commonly used support facilities in coal mines. The columns in the hydraulic props are the main load-bearing components, and the power drive of the hydraulic props is mostly directly powered by electricity. During the coal mining process, it is difficult to prevent sparks (fire) from being generated due to various factors such as problems with the circuit itself and improper use of electricity. Summary of the invention

The emulsified oil passes through the oil inlet filter and the high-pressure one-way valve, and is provided to the power support of the single column, and is pressurized to the required pressure of the single column; when the downhole water pressure is less than 1.5MPa, adjust the pneumatic two-position two-way valve to select manual mode, and the compressed air passes through the air inlet stop valve, the two-way valve, the pneumatic two-position two-way valve, and the air inlet one-way valve into the air storage tank, and then the compressed air enters the pneumatic motor, the oil pump starts working, and the air pressure transmission system is started. The emulsified oil is drawn from the oil tank and passes through the oil inlet filter and the high-pressure one-way valve, and is provided to the power support of the single column, and is pressurized to the required pressure of the single column.

[0008] Furthermore, the wind pressure transmission system also includes a relief valve, and when the pressure is greater than a set pressure of the relief valve, the relief valve opens to maintain the set pressure.
