Technical field
The present invention relates to underground mine water supply system, is especially a kind of generating side that water potential energy is reclaimed using underground mine water supply system
Method.
Background technology
According to the rules, underground coal mine water supply maximum pressure must not exceed 4.0MPa.At present, (buried for ocurrence of coal seam is shallower
Deep 300m~400m) colliery, mostly using ground static pressure pond directly to underground supply water.And exceed 400m coal for depth
Ore deposit cannot directly supply water, it is necessary to take measures just supply water after decompression.Most collieries typically fill on underground main-supply road
If proportional pressure-reducing valve, reduction processing is carried out to hydraulic pressure, hydraulic pressure is met requirement, although this way has reached reduction hydraulic pressure
Requirement, but because the pressure loss that pressure-reducing valve is brought is a kind of waste of resource to water potential energy.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of generating side that water potential energy is reclaimed using underground mine water supply system
Method, its is easy to operate, can reach the purpose for saving the energy and cost while reduction hydraulic pressure meets requirement.
The technical solution of the present invention is to provide a kind of electricity-generating method that water potential energy is reclaimed using underground mine water supply system,
Comprise the following steps：
(1) a static pressure cistern is set on the ground；
(2) main-supply is made, one end of the main-supply is connected with static pressure cistern and communicated, the other end is along pit shaft
Lay to shaft bottom；
(3) after the bottom of main-supply reaches shaft bottom, it is divided into the first main line and the second main line；
(4) it is divided into two tie points in the end of the first main line, is divided into two second in the end of the second main line
Branch road；
(5) two turbine-generator units are arranged, this two turbine-generator units are respectively positioned in the chamber of underground, and respectively by it
In two tie points, the rear and front end of turbine-generator units is equipped with first switch valve, and first switch valve is arranged on
In tie point；
(6) the first switch valve tail end pipeline at two turbine-generator units rear portions is merged, forms first and collect branch road；
(7) proportional pressure-reducing valve is respectively installed on two second branch roads, the rear and front end of proportional pressure-reducing valve is all provided with
There is second switch valve, second switch valve is arranged on the second branch road.
A kind of electricity-generating method that water potential energy is reclaimed using underground mine water supply system of the present invention, wherein, by by constant pressure
Water pump reversion is used as turbine-generator units.
After above structure, compared with prior art, the present invention is a kind of to reclaim water potential energy using underground mine water supply system
Electricity-generating method has advantages below：When underground water, the water in the static pressure cistern of ground flow to hydraulic generator through main-supply
Unit, current rotate the impeller of turbine-generator units, so as to drive what turbine-generator units were generated electricity using water potential energy
Meanwhile effectively the water in supply channel is depressurized, and reach comparatively ideal effect of easing stress；What turbine-generator units were sent
Electricity can be that the electric locomotive battery in the chamber of underground is charged, it can also be used to the illumination of underground chamber after mu balanced circuit voltage stabilizing.
As can be seen here, two turbine-generator units that the present invention is set are easy to operate while reduction hydraulic pressure meets requirement, and
Water potential energy is effectively utilized, is saved specially to underground power supply used trouble, so as to reach the purpose for saving the energy and cost.
The end of second main line is divided into two the second branch roads, and respectively one ratio of installation on this two second branch roads
Pressure-reducing valve depressurizes to the water in supply channel, the purpose is to：In turbine-generator units failure or maintenance, it is ensured that feed pipe
Road normally can supply water to underground.
Inverted by the use of constant voltage water pump as turbine-generator units, can be while hydraulic pressure be reduced, after will not both making decompression
Hydraulic pressure deficiency, will not also make hydraulic pressure excessive.
Brief description of the drawings
Fig. 1 is that main-supply is introduced shaft bottom by the present invention from cistern, and is divided into the first main line and the second main line, so
Turbine-generator units and proportional pressure-reducing valve are arranged on to structural representation when on first, second main line afterwards.
Embodiment
The hair that water potential energy is reclaimed using underground mine water supply system a kind of to the present invention with reference to the accompanying drawings and detailed description
Method for electrically is described in further detail：
As shown in figure 1, in this embodiment, a kind of hair that water potential energy is reclaimed using underground mine water supply system of the present invention
Method for electrically, comprise the following steps：
(1) a static pressure cistern 10 is set on the ground；
(2) main-supply 11 is made, one end of the main-supply 11 is connected with static pressure cistern 10 and communicated, other end edge
Pit shaft 12 to lay to shaft bottom；
(3) after the bottom of main-supply 11 reaches shaft bottom, it is divided into the first main line 13 and the second main line 23；
