Abstract
The utility model relates to a surge chamber provided with trash racks inside and aims to provide a surge chamber provided with trash racks inside, wherein the surge chamber provided with the trash racks inside is simple in structure and convenient to construct to prevent trash from entering a power generator set. The technical scheme is that the upper stream of the surge chamber provided with the trash racks inside is connected with a pressure headrace, and the lower stream is connected with a pressure pipeline. The surge chamber provided with the trash racks inside is characterized in that the cage-shaped trash racks are arranged in the position of a water inlet of the pressure pipeline inside the surge chamber, the trash racks comprise a vertical trash rack and a horizontal trash rack arranged at the top of the vertical trash rack, and a trash collecting pit is arranged at the bottom of the surge chamber on the upper stream of the trash racks. The surge chamber provided with the trash racks inside is applicable to hydropower projects where trash racks are difficult to arrange on the head portion of a conduit system.
Description
Technical field
The utility model relates to a kind of surge-chamber of internal placement trashrack.Be applicable to the Hydropower Project that the diversion system stem arranges that trashrack has difficulties.
Background technology
Build run-of-river power station in natural lake or built reservoir, if it is huge that construction period natural lake or reservoir level can't reduce or reduce the economic loss that water level causes, orographic condition is not suitable for again adopting the mode of arranging water-retaining cofferdam to build hydropower station diversion water inlet, and this adopts under water rock plug technology to build water inlet often.
Flood the problems such as dark, that cavity entrance shape is irregular under water yet adopt water inlet that this special technique builds to exist, ordinary circumstance can't be before water inlet or water inlet internal placement trashrack.But according to the operation needs of Hydropower Plant, therefore the layout trashrack in must the diversion system runner before generating set is sought a kind of suitable feasible trashrack and is arranged that solution is very important.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of surge-chamber of internal placement trashrack of simple in structure, easy construction, enter generating set to prevent dirt.
The technical scheme that the utility model adopts is: a kind of surge-chamber of internal placement trashrack, the surge-chamber upstream connects the pressure diversion road, the downstream connects pressure pipeline, it is characterized in that: in surge-chamber, the pressure pipeline water inlet arranges and protect cage shape trashrack, described trashrack comprises vertical trashrack, and the horizontal trashrack that is arranged at vertical trashrack top; The dirty hole of layout collection, surge-chamber bottom of described trashrack upstream.
The trashrack pier is arranged at described vertical trashrack back, and described horizontal trashrack border arranges that concrete bracket, bottom arrange brace summer.
Described trashrack is arranged in the maximum span place of surge-chamber.
Described surge-chamber upstream is provided with the passage of removing contamination of vehicle of removing contamination that can pass through, and the passage of removing contamination is communicated with the pressure diversion road through the large span access door.
The described passage of removing contamination is formed by a construction hole reconstruction.
Described surge-chamber top is equipped with dirt lifting facility.
The beneficial effects of the utility model are: 1, for the intake of hydropower station that adopts special technique to build, as before water inlet or water inlet internal placement trashrack have difficulties, the utility model technology is arranged trashrack in surge-chamber, can prevent effectively that dirt from entering generating set.2, collection dirty hole is set in the utility model in the trashrack upstream, reduces the impact of dirt accumulation on power benefit before trashrack.3, arranged that two kinds of modes of removing contamination cooperatively interact and removed contamination, the mode of removing contamination is convenient, flexibly, reliable, for the safe and reliable operation in power station provides assurance.
Description of drawings
Fig. 1 is layout plan of the present utility model.
Fig. 2 is sectional side elevation of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, surge-chamber 1 upstream connects pressure diversion road 2, and the downstream connects pressure pipeline 3.When utilizing electrical generation water stream by the simple-type surge-chamber in the present embodiment, the characteristic that runner sudden expansion, flow velocity are die-offed is in surge-chamber 1, pressure pipeline 3 water inlets arrange trashracks 4, satisfy the design specifications requirement for making electrical generation water flow through grid current speed, trashrack 4 is arranged in surge-chamber maximum span place.For preventing that dirt from entering downstream canal, " guarantor's cage " shape that trashrack should be arranged to fix namely except along water (flow) direction is arranged vertical trashrack 4-1, also needs at the vertical horizontal trashrack 4-2 of trashrack 4-1 top layout.Trashrack pier 5 is arranged at back at vertical trashrack 4-1, and trashrack horizontal support power is provided; Arrange that in horizontal trashrack 4-2 border concrete bracket, bottom arrange brace summer 6, provide trashrack vertical supporting power, to guarantee the trashrack safe and stable operation.For dirt accumulation before reducing trashrack affects power benefit, the surge-chamber 1 dirty hole 7 of layout collection, bottom in trashrack 4 upstreams.
Dirt for cleaning trashrack 4 the place aheads, there is following dual mode to be used in conjunction with: the passage of removing contamination (normal adopt a construction hole reconstruction) 1) to be set in surge-chamber 1 upstream to communicate with the external world, the passage of removing contamination is communicated with pressure diversion road 2 through large span access door 8, and the vehicle of removing contamination can enter surge-chamber 4 bottoms from the passage large span mandoor 8 of removing contamination and carry out clean-up operation; 2) at surge-chamber 1 top layout dirt lifting facility, for the dirt that swims in the surge-chamber 1 interior water surface, can from surge-chamber 1 top enter collect after, concentrate lifting.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
