Abstract
The utility model relates to a trash rack of a hydropower station. The utility model aims to provide a trash rack which can effectively block floating sundries at a water inlet and ensure normal operation of the hydropower station and has the characteristics of simple structure and lower cost. The technical scheme comprises that, the trash rack of the hydropower station is characterized by comprising a floating rack body floating on the water and surrounding the front side and left and right sides of a water inlet, wherein the floating rack body is located in the water in an up-down swinging manner through two connecting arms, floating rack side arms on two ends of the floating rack body respectively stretch to the left and right directions of a water inlet guard wall and are respectively contacted with the outer wall of the water inlet guard wall through an idler wheel, a plurality of support rods overhanging into the water are distributed on the outer edges of the floating rack body and the floating rack side arms, and a block net is vertically paved in the water through the support rods.
Description
Technical field
The water surface that the utility model relates to a kind of power station blocks dirty device, is specifically arranged on the trashrack of intake of hydropower station.
Background technology
In power station in running, need interception to swim in the foreign material (household garbage that comprises the plant rubbish such as tree limb, fallen leaves, pasture and water and the mankind) in the water surface or water body, in order to avoid cause, water inlet stops up (affecting inflow), impact is normal produces (avoiding occurring the accident that relevant device damages).Conventionally adopt manual type to tackle floating foreign material.But which not only wastes time and energy, production efficiency is low, and cannot uninterruptedly tackle continuously.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, a kind of trashrack of power station is provided, this trashrack should be able to effectively stop the floating foreign material at water inlet position, guarantees the normal operation in power station, and has simple in structure and lower-cost feature.
The technical solution of the utility model is: a kind of trashrack of power station, it is characterized in that, and this trashrack comprises and swims on the water surface and enclose the scaffold main body of blocking in water inlet front and left and right side; Described scaffold main body can be swung up and down and is positioned in waters by two linking arms, and the scaffold side arm at scaffold main body two ends extends and by a roller, contacts with water inlet revetment outer wall respectively toward the left and right directions of water inlet revetment respectively; The outer side edges of described scaffold main body and scaffold side arm is along all arranging and some support bars that dangle to water separately having a barrier to be vertically laid in water by these support bars downwards.
The two ends of described linking arm are hinged with water inlet revetment and scaffold main body respectively.
Described scaffold main body and scaffold side arm form by the steel-pipe welding that is being coated foamed material.
Between described two linking arms, arranging the reinforcement arm for increasing structural strength.
The length of described every support bar is that the spacing between 5-10 rice and support bar is 1-2 rice.
The beneficial effects of the utility model are:
The utility model comprises scaffold main body and is arranged in the barrier in water, scaffold main body can drive barrier lifting along with SEA LEVEL VARIATION, effectively in block water, foreign material pass through water inlet, therefore without arranging that special messenger salvages (clearing up at set intervals barrier), not only improve operating efficiency, and guaranteed device security; Meanwhile, of the present utility model relatively simple for structure, cost is also lower.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of trashrack of power station, comprises the scaffold main body 1, linking arm 4, support bar 5, the barrier 6 that swim on the water surface 20; Described scaffold main body is arranged in front and the side, two of left and right of water inlet 10, and form enclosing and block the enclosing of periphery of water inlet, and along with the lifting of water level fluctuates; The lateral length of scaffold main body (distances in Fig. 2 between two end points 1-1) is greater than the width of water inlet.
One end of described linking arm is hinged in scaffold main body rotationally by the first rotating shaft 4-1, and the other end is hinged on the outer wall of water inlet revetment 10-1 rotationally by the second rotating shaft 4-2; Article two, between linking arm, be also connected with the reinforcement arm 6 for increasing structural strength; Described scaffold main body can swing up and down by these two linking arms the front (swinging around horizontal axis) that is positioned at water inlet.
The scaffold side arm 2 at described scaffold main body two ends all extends toward water inlet direction, and the front end of every scaffold side arm is fixed a roller 3(roller and is ridden on the outer wall of water inlet revetment), this roller when scaffold main body fluctuates along revetment outer wall roll (motion track 11 of roller as shown in Figure 4).
On this trashrack, also arranging some support bars, these support bars are vertically arranged in the outer side edges edge of scaffold main body and scaffold side arm, these support bars dangle downwards to the degree of depth certain in water and support bar upper berth handicapping block (conventionally adopting nylon wire), thereby barrier is vertically positioned to (barrier is fixed on these support bars) in water, makes barrier near the waters of certain depth water inlet can be surrounded effectively to stop foreign material pass through; The height of described barrier and the size of support bar adapt, and the size of the length of barrier and scaffold main body and linking arm adapts; For guaranteeing that barrier has suitable obstruction area and enough intensity, the length of described support bar is 1-2 rice in the spacing between 5-10 rice and between support bar, and the length of scaffold main body is between 5-10 rice, and the length of linking arm is between 5-10 rice.
Described scaffold main body and scaffold side arm dot by being coated in foamed material 30(figure) steel pipe (diameter of steel pipe according to specific requirement determine) be welded; This foamed material can be that (its cross section as shown in Figure 5 for the foamed pipe of outsourcing; Foamed pipe can be that a plurality of short foamed pipe continue and form, or the foamed pipe of semi-cylindrical is surrounded formation), or foam strip (being bundled on scaffold main body and scaffold side arm with band rope), so the utility model possess certain buoyancy can be by barrier and the support bar holding of supporting use thereof in water; When water level just occurs changing, the utility model can automatic lifting to guarantee good Intercepting effect (water (flow) direction is as shown in arrow A in Fig. 2).
In addition, according to the difference of implementing waters, the length of scaffold main body and linking arm in the utility model is, the length of support bar and spacing all can be made corresponding adjustment.
