A stoplog gate chamber and a grid storage groove are arranged inside the upper end of the framework supporting structure, and a traffic channel is arranged on the top face of the framework supporting structure. The hydropower station water inlet structure combines the advantages of a tower shore type water inlet and a vertical well type water inlet, and capable of achieving the purpose of being reasonable in arrangement, safe and reliable, and economical and practical.
Description
Technical field
The utility model relates to a kind of intake of hydropower station structure.
Background technology
The large medium-size station of present centralized exploitation, the tower or vertical shaft type of the more employing bank of its power station water inlet.If geological conditions is unfavorable for horn mouth is located in the rock mass of bank, generally adopt the bank tower intake, in the tower that trashrack, horn mouth and gate are connected with the bank is connected.This type of structural shape open cut amount is large, the stability of high slope problem easily occurs, and tower body concrete work amount is large.If geological conditions allows, namely rock mass is complete, stable and be convenient to the bank slope of external traffic, should adopt shaft intake, i.e. excavating shaft near rock mass the tunnel import, and gate is placed in mountain massif shaft-well, and only trashrack is built in outside bank slope.In order to reduce the open excavation amount outside the slope and to increase the stability of engineering slope, trashrack back side slope is generally the slope, trashrack is built by the mountain, lean in the hillside, this type of structural shape is simple and reliable, good seismic performance, and excavated volume and amount of concrete all less, but quote flow trashrack difficult arrangement when too large.
Along with the raising to environmental protection understanding, require also should solve the problem of low-temperature discharge when guaranteeing power benefit.Therefore, large reservoir that range of stage large good for adjusting function requires to adopt the structural shape of stratified pumping, by the control elevation of fetching water, can effectively solve the low-temperature discharge problem, satisfies the fish reproduction requirement.The Stoplog gate pattern that the large medium-size station stratified pumping adopts machinery to control more, be that Stoplog gate is for the main member of controlling the water intaking elevation, be arranged in the water inlet leading edge, be generally the plate steel gate structure, by increasing or reduce gate flap quantity reaching the purpose of controlling water intaking, and often with standby trashrack groove general be stoplog groove.For the normal operation of Stoplog gate and be convenient to open and close, the General Requirements stoplog groove uprightly designs, the power station of therefore adopting the Stoplog gate stratified pumping, the general bank tower intake pattern that adopts at present.
Though above-mentioned bank tower intake structure is convenient to arrange stoplog groove, this type of structural shape open cut amount is large, the stability of high slope problem easily occurs, and tower body concrete work amount is large, and cost is higher.In the situation that geological conditions allows, can adopt shaft intake, though it is simple and reliable for structure, excavated volume and concrete work amount are all less, and anti-seismic performance is good, but quote flow trashrack difficult arrangement when too large, and the Recumbent trashrack is unfavorable for the gate operation of Stoplog gate stratified pumping and opens and closes.
The utility model content
It is little and cross the intake of hydropower station structure of grid current speed can satisfy large flow the time that the technical problem that the utility model solves is to provide a kind of native stone excavated volume.
The technical scheme that its technical problem that solves the utility model adopts is: the intake of hydropower station structure, comprise the trashrack structure that is arranged on the vertical shaft type gate structure in massif and is arranged on the massif outside, described trashrack structure vertically arranges, and is connected with frame support structure between trashrack structure and massif slope.
Be further: described frame support structure inside is provided with a plurality of cavitys, be provided with diaphragm structure between adjacent two cavitys, be provided with on described diaphragm structure be used to the concora crush hole that is communicated with adjacent two cavitys, also be provided with on frame support structure for the concora crush hole with the internal communication of cavity and trashrack structure.
Be further: the end face of described frame support structure is provided with traffic aisle.
Be further: inside, described frame support structure upper end is provided with stoplog every storehouse and storage grid groove.
The beneficial effects of the utility model are: this water inlet structure can utilize good geological conditions.Vertical shaft type gate structure in above-mentioned massif namely is arranged in the gate shaft section in mountain massif shaft-well, can reduce the earthwork evacuation amount like this, reduces the engineering slope height, and can reduce the concrete work amount of lock chamber section, saves engineering cost.This part has kept the advantage of shaft intake.The trashrack structure is vertically arranged, and structure has just possessed the advantage of bank tower intake, has solved the problem of quoting the trashrack difficult arrangement of flow when large, crosses grid current speed in the time of can satisfying large flow.The upright designing requirement of gate slot when having satisfied again the Stoplog gate stratified pumping, and be convenient to the front operation of removing contamination of trashrack.Adopt frame support structure to connect between the slope of upright trashrack structure and its back, rigidity and trashrack structure are complementary, structure is slim and graceful, amount of concrete is less, when geological process, its Earthquake Inertia Force Acting is also little, and the framework inner space not only can double as Stoplog gate storage vault and storage grid groove etc., and its top can facilitate communications and transportation by road is set.And frame support structure can also increase the rigidity of trashrack structure, strengthens its structural stability and margin of safety.This structural shape concentrated the advantage of the tower and shaft intake of bank, makes structure reach connection and reasonable arrangement, safe and reliable, economic and practical purpose.
Description of drawings
Fig. 1 is the schematic diagram of intake of hydropower station structure of the present utility model;
Be labeled as in figure: trashrack structure 1, vertical shaft type gate structure 2, cavity 3, diaphragm structure 4, concora crush hole 5, frame support structure 6, slope 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, intake of hydropower station structure of the present utility model, comprise the vertical shaft type gate structure 2 that is arranged in massif and the trashrack structure 1 that is arranged on the massif outside, described trashrack structure 1 vertically arranges, and trashrack structure 1 and its are connected with frame support structure 6 between massif slope 7 behind.Said frame braced structures 6 can with trashrack structure 1 monobloc cast.
In order to reduce amount of concrete, and reduce Earthquake Inertia Force Acting and the sliding force that concrete produces, as shown in Figure 1, described frame support structure 6 inside are provided with a plurality of cavitys 3, be provided with diaphragm structure 4 between adjacent two cavitys, be provided with on described diaphragm structure 4 be used to the concora crush hole 5 that is communicated with adjacent two cavitys, also be provided with on frame support structure 6 for the concora crush hole 5 with the internal communication of cavity and trashrack structure 1.Can reduce by concora crush hole 5 is set the hydraulic pressure that bears in cavity, reduce diaphragm structure stressed.Frame support structure 6 is conducive to improve the resistance to overturning of trashrack structure 1.
In order to take full advantage of the inner space of frame support structure, as shown in Figure 1, described frame support structure 6 inside, upper end are provided with stoplog every storehouse and storage grid groove.
On the basis of the above, in order to facilitate communications and transportation, the end face of described frame support structure 6 is provided with traffic aisle.
