Embodiment
Among Fig. 1, this device is the ground type integrate hydrelectric power station, it by the inlet/outlet gate valve 3 of n bar pressure piping 1, n * m platform hydraulic generator unit 2, generator set, by-pass gate 4, underground pump station 5, master, pay pump 6, the retaining upper storage reservoir 7 that is positioned at the mountain top, water-in and water-out fluid column 9,11, m ground substation 13 being made of n generator set, head 14, also pressure pipe 15 and lower storage reservoir 22 are formed.This device also comprises the water outlet 12 of the trash rack 8 that is located at water intake 10 places of water fluid column 8 into, water outlet fluid column 11, near also pressure pipe road base 20 of the also pressure chamber 16 of setting in the also pressure pipe road 15 of pressure piping 1, eck 17, relief, waist 18,19, sphere.
Described master, a pair pump can be n * 3, and select all or part of putting into operation according to the generating needs.Among Fig. 1 given also pressure chamber 16 with also between the pressure pipe road 15 for the T type is connected, wherein part also is communicated with the fluid column of intaking in pressure pipe road 15, the also pressure pipe road 15 of another part is communicated with the water outlet fluid column.Described lower storage reservoir 22 is when upper storage reservoir 7 water levels occur being lower than head line 14, replenishes the river course at water source to upper storage reservoir 7 through water outlet fluid column 11.
That Fig. 2 provides is the embodiment of water-in and water-out fluid column 9,11 by underground circulating line formation upper storage reservoir 7, and related integrate hydrelectric power station structure is same as above.
Fig. 3 has provided the plan structure figure of this device, in the figure, has utilized water sources such as river, river, lake, sea, reservoir as upper storage reservoir 7, and the water-in and water-out fluid column is all by connections such as river, river, lake, sea, reservoirs, so do not need lower storage reservoir.The position of building a station of described integrate hydrelectric power station can be that tunnel, valley etc. are located.
Fig. 4 is the sectional view along the A-A direction of Fig. 3.Each generator set among the figure is followed successively by the arrangement mode that reduces gradually.
Fig. 5 is that each substation of integrate hydrelectric power station is all-sealed, and the latent cascaded structure form that is placed in the water.In this kind mode, also the pressure pipe road can be straight-tube, and its upper oral part directly is connected with the water source.
Among Fig. 6, also the chamber of pressure is a U type structure.The described also chamber of pressure, this integrated generation station float 18 that is in operation contains free the appearance, so be fluid column equivalent head equivalent pressure, be called for short and also press maybe when pressing, the function of also pressing chamber 16 is to allow float 18 come-ups, because float inner chamber bottom is filled with water, makes it be vertical and floats, under normal operation, making floating waist 19 support eck 17 to come-up, reach the not effect of earial drainage, is that next substation unit transmits equivalent head equivalent pressure power simultaneously.The described also chamber of pressure can be one or more groups.Also press indoor float to discharge or to increase the amount of being filled with water of its inner chamber by arrangement submersible pump thereon according to the buoyancy needs.Should maintain certain free clearance between described eck 17 and the float 18, be convenient to it and float automatically up and down.In pressure piping design, the high speed flow pipeline section of generator set should be lacked, and the pressure piping large-section is flowed pipeline section at a slow speed and should be grown.
In integrate hydrelectric power station end portion, have when pressing pumped storage pumping station 5, inhale circulation to form pump, it is main, paying pump 6 total installations of generating capacity should be more than or equal to the electric motor power of three times of last substation generator set, be convenient to by turns work such as pumped storage, standby, maintain and replace, to satisfy the flow velocity requirement of n bar pressure piping at any time.
Owing to used and also pressed chamber, pumping station, make the hydraulic loss after substation unit guide vane wheel is gone up in fire hose impact, when the fire hose impacts next substation and also presses the chamber, just recovered the equivalent pressure power of this substation fluid column equivalent head naturally, so just guaranteed the fire hose in different ought depressing in order forward, impact force is unattenuated.Pumping station is ceaselessly being discharged circulating water water outlet fluid column mouth when depressing, and is reduced to upper storage reservoir cooling recirculation and uses.
