Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further illustrated.
As shown in fig. 1,1 He of large-scale powerhouse structure of run-of-river power plant described in the utility model, including upstream barricade
Downstream barricade 2, is hydraulic turbine Factory Building 3 between upstream barricade 1 and downstream barricade 2, the bottom of hydraulic turbine Factory Building 3 is provided with water
Wheel unit 4, is provided with worm frame 5 in the lower section of water turbine set 4；In upstream, the bottom of barricade 1 is provided with water inlet flow channel 6, institute
State water inlet flow channel 6 to connect with worm frame 5, in downstream, the bottom of barricade 2 is provided with draft tube 7, the draft tube 7 is tied with spiral case
Structure 5 is connected, also including the roof 8 being arranged at the top of hydraulic turbine Factory Building 3；The roof 8 simultaneously with upstream barricade 1 and downstream barricade
2 connections, and the link position of the roof 8 and upstream barricade 1 is located at the middle part of upstream barricade 1.
Above by roof 8 is directly connected with upstream barricade 1 and downstream barricade 2, while by roof 8 and upstream barricade 1
Link position be arranged on the middle part of upstream barricade 1, its purpose is to play right by the effect of roof 8 and downstream barricade 2
The support effect of upstream barricade, can so improve the ability that upstream barricade 1 bears hydraulic pressure, and can cause upstream barricade, downstream
Barricade and roof etc. effectively constitute hyperstatic structural relation, to improve the structural strength of whole powerhouse of hydropower station.Certainly,
The structural strength on roof 8 in addition to it should meet the weight that can support itself should also be able to bear which and be subject to upstream to keep off
2 pressure applied of wall 1 and downstream barricade.
In addition, in order to ensure that roof 8 can provide enough structural strengths, this utility model is further by the upstream barricade
1st, downstream barricade 2 and 8 three of roof are concrete formed by integrally casting molding.So, it is in be completely fixedly connected relation between three,
Its overall stability can be improved, and then improves the ability that upstream barricade 1 bears hydraulic pressure.Certainly, integrally poured using concrete
During injection forming, typically corresponding reinforcing bar is internally provided with which, now in order to improve the annexation between above-mentioned three, can be by
Reinforcing bar in upstream barricade 1 is directly fixedly connected with the reinforcing bar in roof 8；In the same manner, by downstream barricade 2
Reinforcing bar also directly can be fixedly connected with the reinforcing bar in roof 8.
More specifically, this utility model further arranges elevation H1 at roof 8 and 1 link position of upstream barricade less than upper
The design peak level H2 in trip river course.Such benefit is to cause upstream barricade 1 to be subject to the support force on roof 8 to be located at as far as possible
Its medium position, so can reduce the torsion load being subject to inside upstream barricade 1 as far as possible, and then reduce the stress of upstream barricade 1
Situation.Certainly, roof 8 should ensure that the space size of hydraulic turbine Factory Building 3 below meets the situation of design requirement as far as possible
Under take above-mentioned setting.It should be noted that above-mentioned design peak level H2, which is can when corresponding powerhouse of hydropower station is designed
With the design parameter for obtaining, to those skilled in the art, which can be by the acquisition of conventional technique means,
In this utility model, only it is directly to use the parameter, is not related to specific acquisition side method.
In addition, multiple lightlng holes 9 also further can be provided with roof 8, the action type of lightlng hole 9 can make natural light saturating
Hydraulic turbine Factory Building 3 after crossing lightlng hole 9 for lower section provides natural lighting, can reduce artificially lighting usage amount, Jin Erjie with this
About energy consumption, reduces operating cost.Certainly, in order to avoid the rainwater of top drops into the hydraulic turbine Factory Building 3 of lower section by lightlng hole 9
It is interior, generally corresponding glazing structure can be installed at lightlng hole 9, so both ensure that passing through for natural light, and protected again
The isolation to rainwater is demonstrate,proved.
Under normal circumstances, on upstream barricade 1 and downstream barricade 1 towards hydraulic turbine Factory Building 3 side be respectively arranged with it is right
The crane bracket 10 that should coordinate, in order to support corresponding crane or driving.The benefit for so arranging is, due to this practicality newly
The roof 8 that can bear 2 load of upstream barricade 1 and downstream barricade will be provided with to tie in type between upstream barricade 1 and downstream barricade 2
Structure, thus it is above-mentioned be provided with crane bracket 10 in the case of, when crane load has been born, roof 8 is may also function as to both sides
Upstream barricade 1 and downstream barricade 2 between support effect, and then improve overall structural strength.
It is furthermore preferred that in this utility model further by roof 8 from 1 side of upstream barricade to 2 side of downstream barricade in downward
It is obliquely installed.So arrange benefit be, can be in flood period, after flood overflows across upstream barricade 1, can be quickly along inclination
Roof it is dirty, and be drained in downstream river course, can so avoid causing the damage to roof, flood, reduction as far as possible that can be
It is likely to occur the situation for flooding hydraulic turbine Factory Building 3.Referring to the drawings shown in 1, the value of its tilt angle theta is typically preferably set
Scope is 5 °～30 °, and it is 10 ° for example to arrange tilt angle theta.
Above-mentioned large-scale powerhouse structure of run-of-river power plant described in the utility model, keeps off for upstream because adopting 8 structure of roof
Wall 1 provides certain support force, therefore can under equal conditions provide the bearing capacity of upstream barricade 1, it is possible to decrease upstream barricade 1
Concrete and amount of reinforcement.Certainly, as the concrete and amount of reinforcement of upstream barricade 1 are reduced, therefore appropriate
In the case of can by this utility model be used for the upstream depth of water more than 80m situation.
