Abstract
The utility model belongs to a water taking structure of a water diversion and power generation system of a hydropower station, and in particular relates to a water inlet water guide stop log with a surface layer water flow taking requirement. The water inlet water guide stop log is characterized by comprising a water guide stop log main body, a horizontal support beam and a water guide stop log support wall, wherein the water guide stop log main body is formed by the connection of a plurality of steel stop logs, and is arranged at the upstream side of the water inlet; two ends of the water guide stop log main body are supported in stop log door grooves at the top parts of two parallel water guide stop log support walls; four horizontal communicated holes are formed respectively and correspondingly on the wall bodies at the lower half parts of the two water guide stop log support walls; a plurality of horizontal support beams are arranged between the two water guide stop log support walls; and the stop log door grooves are internally provided with rails. According to the water inlet water guide stop log provided by the utility model, the number of stop logs in the water guide stop log main body is changed so as to adapt to the water level variation of the reservoir, thus the requirement that surface layer water is taken for a water diversion building is met.
Description
Technical field
The utility model belongs to the water intaking structure of power station diversion and power system, and the water inlet water guide stoplog of getting top layer current requirement is particularly arranged.
Background technology
The conventional hydropower station water inlet generally is made up of trashrack, Emergency Gate and Emergency Gate.But,, need to guarantee that the storehouse water than the depths does not flow to downstream, in order to avoid downstream ecology and biota produce serious harm perhaps owing to the downstream ecology requirement when the reservoir level change is bigger.This moment, conventional water inlet can not guarantee under various water level conditions, made the water that gets into power station pressure pipes can only be from reservoir surface.
Summary of the invention
The purpose of the utility model provides a kind of water inlet water guide stoplog, and it can effectively quote the reservoir surface current, and avoids deep layer storehouse water to get into downstream.
The technical scheme of the utility model: design a kind of water inlet water guide stoplog; It is characterized in that: comprise water guide stoplog main body, cross binding beam and water guide stoplog knee wall; Described water guide stoplog main body is to be connected and composed by a plurality of steel stoplogs; Water guide stoplog main body is arranged on the upstream side of water inlet, and the two end supports of water guide stoplog main body is in the stoplog groove at two parallel water guide stoplog knee wall tops; On the latter half body of wall of described two water guide stoplog knee walls respectively correspondence have four and laterally gang up the hole, be provided with a plurality of cross binding beams between two water guide stoplog knee walls; Be provided with track in the described stoplog groove.
Described cross binding beam is a reinforced concrete structure.
The section of described cross binding beam is circular or other are streamlined.
The beneficial effect of the utility model is: the described structure of the utility model, it can effectively quote the reservoir surface current, and avoids deep layer storehouse water to get into downstream.This structure makes full use of bank tower intake concrete structure, avoids being provided with in addition special stratified pumping structure, and adopts water guide stoplog structure, satisfies the requirement of getting superficial water through changing stoplog quantity.Be provided with on the water guide stoplog knee wall area enough big gang up the hole, make the current can lateral flow, the test card exposed installation can effectively improve flow condition after putting and ganging up the hole, reduces eddy current, reduces head loss.The cross binding beam is set increases the lateral stiffness of partition wall extension, and cross binding beam section is circular or other streamlined flow conditions that improve.
Description of drawings
Below in conjunction with embodiment and embodiment accompanying drawing the utility model is further specified, but not as the qualification to the utility model:
Fig. 1 is the water inlet water guide stoplog drawing in side sectional elevation of the utility model embodiment;
Fig. 2 is the water inlet water guide stoplog top layer layout plan of the utility model embodiment;
Fig. 3 is the water inlet water guide stoplog bottom layout plan of the utility model embodiment.
Among the figure: 1, water guide stoplog main body; 2, water guide stoplog access door storehouse; 3, water guide stoplog knee wall; 4, cross binding beam; 5, trashrack; 6, Emergency Gate; 7, Service gate; 8, laterally gang up the hole; 9, stoplog groove; 10, track.
The specific embodiment
The structure that is not described in detail in an embodiment, its structure is identical with existing known structure.
Trashrack 5, Emergency Gate 6, Service gate 7 are the conventional structure of general water inlet among the figure, and its effect is to accomplish normal operation of the conventional water inlet in power station and the essential structure that is provided with of inspection and repair shop.
Shown in Fig. 1-3; The water guide stoplog structure of present embodiment comprises water guide stoplog main body 1, cross binding beam 4 and water guide stoplog knee wall 3; Described water guide stoplog main body 1 is to be connected and composed by a plurality of steel stoplogs, and merogenesis vertical height 2m promotes operation through the top headstock gear; When reservoir level changes, can adjust stoplog quantity to adapt to SEA LEVEL VARIATION.Water guide stoplog main body 1 is arranged on the upstream side of water inlet, and the two end supports of water guide stoplog main body 1 is in the stoplog groove 9 at two parallel water guide stoplog knee wall 3 tops; On the latter half body of wall of described two water guide stoplog knee walls 3 respectively correspondence have four and laterally gang up between hole 8, two water guide stoplogs knee wall 3 and be provided with a plurality of cross binding beams 4; Being provided with steel track 10 in the described stoplog groove 9 supplies stoplogs to promote and with regard to bit manipulation.Said track 10 also can be other metal.
When the water guide stoplog need change dash height or maintenance, can the water guide stoplog be placed in the water guide stoplog access door storehouse 2 through opening and closing device.
The utility model is through being arranged on the additional water guide stoplog structure at the upper reaches; Block water bottom of the reservior layer current get into water inlet; Through the checking of hydraulic model test, can guarantee to get into the interior current of diversion tunnel from the 10m scope of top layer, thereby satisfy the requirement of downstream ecology water.
The section of described cross binding beam 4 is circular or other are streamlined.
