Description

Net bag type trash blocking device

Technical Field

The utility model relates to the technical field of hydroelectric power generation, in particular to a net bag type trash holding device for hydroelectric power generation.

Background

With the current environmental damage, many riverbed low head hydroelectric stations have increased in fouling. More and more hydropower stations adopt floating type dirt blocking rows as a defense line for blocking floating dirt from entering a water inlet of a power generation plant. Traditional trash rack adopts the combination of single cylinder wiring, and both ends are fixed on bank anchor spare, form integral combination trash rack, can change along with the lift change of rivers, form to block dirty floating row, reach effective interception effect on water, keep apart the interception to the various environment debris rubbish above the water. The trash rack is in a horizontal straight line type, floating objects and impurities are easy to accumulate in the middle of the trash rack, the trash rack is difficult to clean, once more impurities are accumulated, blockage can be caused, water impact is easy to happen, and the trash rack is not ideal in trash rack effect.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provides a tuck net type trash holding device which is reasonable in structure, good in impurity cleaning effect and capable of effectively guaranteeing cleanness and sanitation of a water area.

In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the tuck net type trash blocking device comprises uprights fixed on shore bases on two sides of a water surface, upright stay ropes are connected to the uprights, a blocking net pull rod is connected between the two upright stay ropes, tuck net stay ropes are connected to the blocking net pull rod and connected with flaring rings, the flaring rings are connected with tucks, the tucks are multiple and are arranged on the water surface between the two uprights in a row through the corresponding flaring rings, blocking net columns are installed in water in the direction of net openings of the tuck net, the blocking net columns are multiple, the blocking net columns are combined to form an arc-shaped net blocking area, the inner arc surface of the net blocking area is right opposite to the direction of the tucks, a trash blocking net is arranged in the water inlet direction of the blocking net columns, the trash blocking net is connected with the blocking net columns through corresponding net ropes, and blocking strips are arranged between the blocking net columns and the trash blocking net.

The blend stop be many, from top to bottom fix on blocking the net post, the blend stop is the arc, its inner arc face is just to the string bag direction.

The net bags are arranged in at least two rows, and two or more than two upright posts are arranged on each side shore base.

The meshes of the impurity blocking barrier net are larger than those of the net bag.

The string bag is trapezoidal with a large front part and a small back part, the large end of the string bag is connected with the flaring ring, the small end of the string bag is sealed by the net piece, the flaring ring is in a vertically-installed square frame shape, and the vertical walls of the adjacent flaring rings are connected through the net rope.

After the scheme is adopted, the blocking net columns and the impurity blocking nets are combined to form a first impurity blocking area for blocking larger floaters, the blocked floaters can walk to the sides of the bank under the impact of water flow and the guiding action of the outer arc surfaces of the impurity blocking nets and finally are collected at the included angle between the outer arc surfaces of the impurity blocking nets and the bank base, workers can do floaters working at the included angle, and smaller floaters and impurities pass through the impurity blocking nets under the stamping action of water flow and then enter the net bags (the net bag meshes on the front side in the water flow direction are larger than those on the rear side), so that the floaters and the impurities enter the net bags through the flaring rings and are collected through the net bags, the floaters and the impurities are blocked layer by adopting a plurality of rows of net bags.

Fig. 1 is a schematic view of the overall structure of the present invention.

Detailed Description

The utility model will be further described with reference to the accompanying drawings, in which preferred embodiments of the utility model are: referring to fig. 1, the tuck net type trash holding device according to this embodiment includes columns 34 fixed on shore bases on both sides of a water surface, column pull ropes 35 are connected to the columns 34, a blocking pull rod 31 is connected between the two column pull ropes 35, a tuck net pull rope 32 is connected to the blocking pull rod 31, the tuck net pull rope 32 is connected to a flaring ring, the flaring ring is connected to a plurality of tucks 33, the tucks 33 are installed on the water surface between the two columns 34 through corresponding flaring rings after being arranged in a row, the tucks 33 are in at least two rows, the columns 34 on each side shore base are two or more, blocking net posts 36 are installed in the water in the direction of the net mouth of the tucks 33, the blocking net posts 36 are multiple, the blocking net posts 36 are combined to form an arc-shaped blocking net area, the inner arc surface of the blocking net area faces the direction of the net 33, a blocking net 37 is installed in the water inlet direction of the blocking net post 36, and the meshes of the blocking net 37 are larger than meshes of the net 33.
