Abstract
The utility model relates to a floating drain grating which is used for a hydropower station to prevent drain from entering a water inlet of a power generation factory, a pull rod is arranged between floating boxes, one end of the pull rod is hinged with a floating box by a shaft in a vertical direction, the other end of the pull rod is hinged with the another floating box by a shaft in a horizontal direction, and floating pontoons which are arranged on both ends of the drain grating are fixed in a vertical guide groove in a sliding mode. The drain grating has reliable structure and can adapt water level variation, consequently, the drain blocking effect is good, and the safety is high.
Description
Technical field
The utility model relates to a kind of power station that is used for and stops the floating pollutant-blocking grate that dirt enters the power plant building water inlet.
Background technology
Along with present China natural environment suffers serious day by day artificial destruction, many river channel low head hydropower station dirts sharply increase the weight of.Adopted the floating pollutant-blocking grate as stopping the first line of defence that floating pollutant enters the power plant building water inlet on the increasing power station.The pollutant-blocking grate pattern that adopted in the actual engineering of present employed floating pollutant-blocking grate has bamboo raft, metal float, Plastic buoy, steel boom, ferrocement boom etc.The steel boom can also be subdivided into single boom and two boom.The stretch-draw pattern has wire rope stretch-draw, anchor chain stretch-draw.The pollutant-blocking grate end fixedly pattern have two ends be fixing, an end is fixed and other end free floating, two ends are free activity etc.Be that structural shape is varied, ever-changing.
Owing to have many uncertainties and particularity in the design of floating pollutant-blocking grate; and the industry standard that does not also have at present the floating pollutant-blocking grate design that can carry out; in many design works, have certain blindness type; cause pollutant-blocking grate work unreliable, it is undesirable to block dirty effect, thereby causes the flood period dirt often to stop up trashrack; the power station need be shut down and be removed contamination; cause electric quantity loss, the destruction that causes trashrack when serious, the destruction that What is more then causes the pollutant-blocking grate self structure.Therefore, design studies adapts to the variation of reservoir level, and the reliable novel floating pollutant-blocking grate of structural safety own is very important.
The utility model content
In order to improve the reliability of floating pollutant-blocking grate, and further improve the ability that adapts to SEA LEVEL VARIATION, the utility model improves the structure of pollutant-blocking grate.
The pollutant-blocking grate that the utility model provides comprises buoyancy tank, and pull bar is arranged between the buoyancy tank, and pull bar one end is hinged by the hinge on the vertical direction and a buoyancy tank, and the other end of pull bar is just hinged by the hinge on the horizontal direction and another buoyancy tank; Pollutant-blocking grate two ends floating drum slides and is fixed in the vertical guide slot; Vertical guide slot one end in two ends is arranged near on the sluice gate pier of factory building monolith, and the other end is arranged on the bank.
In actual use, pollutant-blocking grate preferably increases safety device, and this safety device comprises many wire rope and fixing steel embedded part.One end of wire rope is connected near on the pollutant-blocking grate of factory building monolith, and for example on the buoyancy tank of pollutant-blocking grate, the other end is connected on the fixing steel embedded part.The steel embedded part is fixed on the factory building monolith.
Because when pollutant-blocking grate is opened at floodgate, pollutant-blocking grate is in the extremely disorderly current near factory building monolith position, owing in most cases there is the effect of reverse flow, the catenary of pollutant-blocking grate is destroyed, the stressed very complexity of pollutant-blocking grate, instead " S " curve has appearred in equilibrium state, and its load can't theoretically calculate, and often causes the failure of pollutant-blocking grate.Safety device 8 makes pollutant-blocking grate be in a catenary state substantially in extremely disorderly current, has improved the reliability and the safety of pollutant-blocking grate self work.
The pollutant-blocking grate that the utility model provides has reliable in structure, can adapt to SEA LEVEL VARIATION, thereby blocks dirty effective, safe.

Fig. 2 is the structural representation (lateral view) of the utility model embodiment;
Fig. 3 is the enlarged drawing of two buoyancy tank coupling parts among Fig. 1;
Fig. 4 is the utility model user mode figure.
Embodiment
Referring to Fig. 1,2 and 3, the floating pollutant-blocking grate is made up of some buoyancy tanks 3, short rod 2, long draw 4, hinge 6,5,2 floating drums of grid leaf, 1,2 cover vertical guide slot 7 and safety device.Some buoyancy tanks 3 and pull bar 2,4 are hinged and connected by hinge 6 head and the tail, form gentle architecture system, fix a grid leaf 5 on each buoyancy tank, and pollutant-blocking grate two ends floating drum 1 has walking support wheel 10 and directive wheel 11 constrains in the vertical guide slot 7.Vertical guide slot one end in two ends is arranged near on the sluice gate pier of factory building monolith, and the other end is arranged on the bank.The pollutant-blocking grate of this structural shape is gentle architecture system.
Pollutant-blocking grate is similar to a catenary under the acting in conjunction of generating diversion current (current flow into the factory building water inlet from reservoir through pollutant-blocking grate), strong wind, wave and floating thing.The stretching force load of pollutant-blocking grate is passed to floating drum 1 by buoyancy tank 3, pull bar 2,4, hinge 5 and acts on guide groove 7 embedded parts at two ends, the buoyancy tank 3 and the pull bar of pollutant-blocking grate are box section, supporting capacity is big, floating drum master supporting is fixed wheel, bearing of fixed wheel adopts rolling bearing, and floating drum lifting in guide groove is flexible.
With reference to figure 4, the pollutant-blocking grate that the utility model provides is provided with safety device.This safety device is made up of many wire rope 8 and the steel embedded part 9 that is fixed in the factory building monolith, and an end of wire rope 8 connects on the buoyancy tank 3 of pollutant-blocking grate, and the other end is connected on the steel embedded part 9 that is fixed in the factory building monolith.
Claims (4)
1, the floating pollutant-blocking grate comprises buoyancy tank, and it is characterized in that has pull bar between the buoyancy tank, and pull bar one end is hinged with a buoyancy tank by the axle on the vertical direction, and the other end of pull bar is just hinged with another buoyancy tank by the axle on the horizontal direction; Pollutant-blocking grate two ends floating drum slides and is fixed in the vertical guide slot.
2, floating pollutant-blocking grate according to claim 1 is characterized in that also being provided with safety device, and this safety device comprises many wire rope and steel embedded part, and an end of wire rope is connected on the pollutant-blocking grate, and the other end is connected on the fixing steel embedded part.
3, floating pollutant-blocking grate according to claim 1 is characterized in that having on the floating drum of pollutant-blocking grate two ends walking support wheel (10) and directive wheel (11), and constrains in the vertical guide slot (7).
4, floating pollutant-blocking grate according to claim 1 and 2 is characterized in that the pull bar between floating drum and buoyancy tank is short than other railing.
