The hydropower station workshop tail water channel is positioned on one side of the river channel (6), and a water outlet of the tail water channel is communicated with the river channel; a left guide wall (2) and a right guide wall (3) are respectively arranged on two sides of the tail water channel, a bottom plate (1) is arranged at the bottom between the left guide wall and the right guide wall, and a sand blocking bank (4) is arranged at a water outlet of the bottom plate; a guide wall (5) is arranged in the river channel, an azimuth angle theta is arranged between the guide wall and the sand blocking ridge, and one end of the guide wall is connected with the left guide wall. The utility model discloses mainly be applied to among the long diversion shore formula factory building tailrace building in hilly area, the utility model discloses a structure can not the high low reaches water level of harmony, and then does not influence the unit and exert oneself, and has reached the purpose that prevents the ballast from getting into the tailrace. Can effectively reduce the stone sediment that gets into in the tailrace to reduce the number of times of scarfing cinder in the tailrace, directly reduce the running cost in power station, the indirect power generation benefit that increases the power station.
Description
Technical field
This utility model relates to a kind of powerhouse of hydropower station tailwater channel and leads wall arrangement, belongs to hilly ground head of district's diversion bank
Formula power plant building tailwater channel arranges technical field.
Background technology
River, knob typically uses cascade development mode to utilize waterpower resourses, in order to make full use of head, and power plant
Room tail water mainly considers to be connected with lower reservoir reservoir level, and for not affecting power benefit, tailwater channel sediment trapping bank height will be less than half
Platform machine generating tailwater level, the effect intercepting riverbed rock ballast is limited.
For hilly ground head of district's diversion power house along river bank, between factory dam, in river course, section, isolated block stone is more, and side slope mostly is heap
Long-pending body, construction waste and construction disturbance cause the loosest rock ballast to roll in river course.The several years ago dam inter-plant gone into operation in power station
Rock ballast in river course is extremely difficult to stable, and during dam flood-discharge in flood season, flood carries the loose rock ballast such as substantial amounts of boulder, block stone and enters
Entering tail water river course, owing to tail water river course width delays, part boulder, block stone can not be washed away by flood, cause rock ballast to deposit at tail water
In canal and outlet section downstream river course thereof, and the rock ballast deposited in tailwater channel is relatively big due to tailwater channel base plate counter-slope, its interior stone
Slag rolls under the effect of generating current in tailwater channel, collision tailwater channel and tail water gate pier, damages structure, time serious
Have to close unit tailwater channel is repaired, affect unit generation and cause electric quantity loss.
Summary of the invention
The purpose of this utility model is, it is provided that a kind of powerhouse of hydropower station tailwater channel leads wall arrangement.To reduce entrance
Rock ballast in tailwater channel, thus reduce tailwater channel and gate pier structural damage, reduce the frequency that power station scarfing cinder is shut down, reach to carry
The purpose of high power station economic benefit.
The technical solution of the utility model:
A kind of powerhouse of hydropower station tailwater channel leads wall arrangement, and described powerhouse of hydropower station tailwater channel is positioned at side, river course, tail
The outlet of water channel communicates with river course；Tailwater channel is respectively provided on two sides with left guide wall and the right side is led wall, left guide wall and the right side and led between wall
Bottom is provided with base plate, and the water outlet of base plate is provided with and blocks sand bank；It is provided with in river course and leads wall, lead wall and block and be provided with orientation between sand bank
Angle θ, leads wall one end and is connected with left guide wall.
In aforementioned structure, described in lead wall height be not less than 5 years or 10 years one meet flood time tailwater level elevation.
In aforementioned structure, described in lead wall length less than or equal to tailwater channel width 1/2.
In aforementioned structure, described in lead the azimuth angle theta of wall less than 45 °.
Compared with prior art, this utility model is mainly used in hilly ground head of district's diversion power house along river bank tailwater channel building
In thing, structure of the present utility model will not the harmony high level of tail water, and then do not affect unit output, and reached to prevent rock ballast from entering
The purpose of tailwater channel.It is effectively reduced the rock ballast entered in tailwater channel, thus the number of times of scarfing cinder in reducing tailwater channel, directly reduce
The operating cost in power station, indirectly increases the power benefit in power station.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1 base plate, 2 left guide wall, 3 right sides lead wall, and 4 block sand bank, and 5 lead wall, 6 river courses.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as new to this practicality
Any restriction of type.
A kind of powerhouse of hydropower station tailwater channel leads wall arrangement, as it is shown in figure 1, powerhouse of hydropower station tailwater channel is positioned at river course 6
Side, the outlet of tailwater channel communicates with river course 6；Tailwater channel is respectively provided on two sides with left guide wall 2 and wall 3 is led on the right side, and left guide wall 2 is with right
Leading the bottom between wall 3 and be provided with base plate 1, the water outlet of base plate 1 is provided with and blocks sand bank 4；Be provided with in river course 6 and lead wall 5, lead wall 5 with
Block and be provided with azimuth angle theta between sand bank 4, lead wall 5 one end and be connected with left guide wall 2.Lead wall 5 and be highly not less than 5 years or 10 years one chance floods
Tailwater level elevation during water.Lead wall 5 length less than or equal to the 1/2 of tailwater channel width.Lead the azimuth angle theta of wall 5 less than 45 °.
Embodiment
This example is as a example by Flos Caryophylli water power station and hair man Hydropower Station.When wall is led in setting, lead wall height with bed load not
Can enter, part suspended load can enter tailwater channel and occupies the principle layout that trade culture is few, it is proposed that uses 5 years one chances or 10
Year one meets flood tailwater level elevation as leading wall rational height.Leading wall length with tailwater channel upstream side barricade as starting point, terminal is pressed
According to build lead wall after do not affect tail water go out stream, rock ballast breach the most downstream roll into tailwater channel be principle, it is proposed that lead wall length little
In or 1/2 being advisable equal to tailwater channel width.Lead wall grid azimuth θ according to lead after wall is built can water conservancy diversion tail the most smoothly
Water enters river course 6, i.e. to reduce the Yong Shuiwei impact on unit generation, the principle occupying river course flood discharge section that again can not be too much
It is arranged.
Arrange that leading wall can reach and do not affecting the premise that power station unit is exerted oneself by above arrangement principle in tailwater channel outer
Under, reduce the purpose of the rock ballast entering tailwater channel.
