Abstract
The utility model discloses a channel type generation device for reutilization of hydropower in a hydropower station. The channel type generation device comprises a 'U'-shaped water channel and an impulse wheel type generator set. The channel type generation device is novel in design, simple in structure, low in cost, strong in operability, wide in application in middle and large scale power stations, and great in developing prospect.
Description
Technical field
The utility model belongs to the new equipment of a kind of water-energy generating electricity of water conservancy industry, the TRT that a kind of water energy secondary utilizes.
Background technology
Energy-saving and emission-reduction are current state basic policies of the Chinese government.Water conservancy is the lifeblood of agricultural, and agricultural is the economic base of country.China is large agricultural country, and water conservancy is the development of left and right sides China agricultural to a certain extent; Simultaneously, China is again the country of a lack of water, how scientifically to utilize existing water resource to be economic service, will be a great problem.China is vast in territory, numerous country fair dike engineering, water storage project, diversion water lift engineering and water power are arranged and supply power transformation engineering, unnumbered dykes and dams, water channel, reservoir and power station are arranged, country has dropped into a large amount of human and material resources and financial resources at water conservancy, if the power station can utilize generating not increase again construction investment in water to greatest extent, this will make a great contribution for our water generating cause.How to maximally utilise water-energy generating electricity, new design and new device are detected in limited specialty, and the paper periodical is not seen and is applied in the reality., the drop of several meters or tens meters through the retaining of culvert pipe under the dam or tunnel, still can be evoked in many power stations, and huge water can run off like this in vain.
Summary of the invention
The inventor is through observation and the thinking in more than 10 years, and discusses with the hydraulic expert and calculate, invented the TRT that a kind of power station water can secondary utilizes, and is fine through theoretical calculation and practical application effect.
The power station that the purpose of this utility model is to overcome present existence is through the phenomenon that the water of culvert pipe under the dam or tunnel can run off, and provides a kind of water can the new TRT of secondary utilization.
The technical solution of the utility model: water channel is built in design below culvert pipe or the tunnel under the dam, its width and pipe (hole) mouthful equal diameters, the water channel plane exceeds the usual delivery port 20-50 centimetre of pipe (hole), water channel becomes 28 degree oblique belows, angle with horizon, make current have guiding through water channel, 20 meters of length make like this these current compile as the optics concave mirror and assemble current the light, water channel can also play the effect of supporting Gu Ba (dike) at the bottom of the dam except water conservancy diversion.The water channel cross section is designed to " U " shape, and the ratio of its Gao Yukuan (half circular diameter) is 1: 1.In canal, install again and impact wheeled generating set, beater wheel blade draft is 1/3rd of the ordinary water depth of channel water, makes that all the other water are zero load to be passed through, and is beneficial to its beater wheel acting to lagging behind, unit quantity 1-2 platform, the quantity of water channel equal culvert pipe or tunnel quantity under the dam.Like this, again secondary utilization generating of water.Mentality of designing of the present utility model is: the device of vane type is changed into the beater wheel device, and the water channel shape of cross section changes " U " shape canal into; Facts have proved that the beater wheel device lacks than other device energy-wasting, " U " shape canal is larger than the instantaneous delivery of other design water.In a medium-sized power station, design head 2m, maximal head 4m, minimum head 2m, unit design discharge 5m
3/ S.Calculate if press the drop of 2m, a year newly-increased generating is 550,000 KMWh, in 0.6 yuan/degree, 330,000 yuan; The package unit costs 50,000 such as one cover water channel and generating, year increases 280,000 yuan economic benefit newly.
The utility model is novel, consists of simply, and strong operability has good DEVELOPMENT PROSPECT.

The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the canal formula generating device structure figure that water energy secondary utilizes.1, water inlet; 2, dam; 3, culvert pipe mouth or tunnel mouth under the dam; 4, impact wheeled generating set; 5, water channel (" U " shape canal)
Fig. 2 is mounting structure figure in the beater wheel generator canal.6, blade; 7, generating set; 8, water channel (" U " shape canal).
The specific embodiment
This device is comprised of water channel and surge generator, and water channel is right after culvert pipe or tunnel mouth under the dam, and its width is decided 20 meters of length on hole (pipe) mouthful diameter; Water channel becomes 28 degree oblique belows, angle with horizon.The impact type power generation unit of 1-2 platform is installed in canal, and the quantity of water channel equals the quantity of culvert pipe under the dam or tunnel.This device is suitable for mixed-flow, tubular power station especially.
Claims (2)
1. one kind is used for the canal formula TRT that the hydraulic energy of hydropower station secondary utilizes, and it is characterized in that: device is comprised of water channel and the wheeled generating set of impact.
2. TRT claimed in claim 1 is characterized in that: long 20 meters of water channel becomes 28 degree oblique belows, angle with horizon, and the water channel plane exceeds manages usual delivery port 20-50 centimetre; Water channel cuts cross section for " U " shape, and its height is 1: 1 with wide ratio, and the quantity of water channel equals culvert pipe quantity under the dam.
