Abstract
The invention discloses a synergy method for waterpower. The intake of the hydraulic generator is set at the bottom or near the bottom of the dam at a grade from 0 degree to 20 degree. The water wheel is set in the water guiding box. And the hydraulic turbines in the water guiding box are arrayed in series. It drives generator by variable speed gear. The outtake of the water guiding box is set an adjust valve. The grade of hydraulic turbines in the water guiding box is from grade 1 to grade 3. The invention would avoid air to entangle and the current would not cause vacuum, and cavitation. When the pressure increases, the same water intake could drive several hydraulic turbines. Thus, the aim of synergy for waterpower would be realized.
Description
Technical field the invention belongs to a kind of method of giving hydroelectric generator synergy.
The existing hydroelectric generator of background technique, its intake pipe tiltedly draws and descends from the dam water surface site, and air can be involved in the pipe, is easy to produce cavitation under swiftly flowing situation, consumes many kinetic energy, and the energy that acts on generator is reduced; On the other hand, pipe allows water lean on deadweight to descend the mode of arrival water turbine along pipe from the position water inlet on dam top, the setting-out that the water turbine place obtains under mobility status is less than the static pressure of the deep water body of same horizontal position all the time, and this is existing unfavorable another major reason of generator efficiency.
Summary of the invention the objective of the invention is to propose a kind of reduce water can reactive power consumption, increase the method for rendeing a service to hydroelectric generator, to overcome the deficiencies in the prior art.
This efficiency increasing method for hydraulic power generation that the present invention proposes, it is characterized in that intake pipe water intake with hydraulic turbine generator is arranged on dam bottom or bottom nearby and with level or less than the gradient settings of 20 degree, the water wheels of water turbine are installed in the water guide case, water turbine is arranged in water guide case troubles connection formula, and water turbine drives generator by speed change gear.The outlet of water guide case is provided with the regulation and control lock.
The water turbine progression of water guide case troubles connection is the 1-3 level.
Intake pipe ingress and water guide tank inlet place all establish the maintenance lock.
The present invention changes generator intake pipe entry position into pressure bigger low water level place from the lower high water level of pressure, avoided air to be involved in, can not produce vacuum in the current, do not produce cavitation, there is not idle energy consumption, water flow pressure increases, and same intake pipe can promote many water turbine, has realized hydroelectric synergy purpose.
Appended drawings 1 is structure principle chart of the present invention (longitudinal section).
Accompanying drawing 2 is structural principle situation plan of the present invention.
Each parts label is among the figure: 1-maintenance lock first; The 2-dam; The 3-intake pipe; 4-maintenance lock second; 5-water guide case; 6-one-level water turbine; 7-secondary water turbine; Three grades of water turbine of 8-; 9-regulates and control lock; The 10-generator.
Embodiment is shown in Fig. 1-2, near the dam bottom, the intake pipe (3) of dam (2) horizontal generator is worn at 1/3rd places of the height of the normal retaining of dam just, and the intake pipe diameter is identical with original unit generator from high water level introducing current.The generator set water guide case (5) of intake pipe below dam is communicated with, establishes maintenance lock second (4) between intake pipe and water guide case, maintenance lock first (1) is established in the intake pipe ingress.The water guide case is the stressed closed device of water turbine, in one to three grade of water turbine (6), (7), (8) of series connection are housed, water turbine directly drives generator (10) generating separately.Establish a regulation and control lock (9) at the end of water guide case,, it is consistent in order to regulate the rotating speed of three water turbine.On same dam body, can establish the unit of a plurality of series, establish two to three grades of water turbine in the same water guide case according to the size and the terrian condition situation of water energy.
So just realized the purpose of three generators of same intake pipe installation, increase generated energy.
