Description
Technical Field
The utility model relates to the technical field of hydroelectric power generation, in particular to a sewage blocking net bag filtering 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 of a transverse water blocking type, is easy to be impacted by water, and has an unsatisfactory trash blocking effect.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a trash rack net bag filtering device.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: the utility model provides a block dirty string bag filter equipment, it is including leading water conservancy diversion net, transition net, pocket net, wherein, leading water conservancy diversion net wherein one end is equipped with the flaring ring, leading water conservancy diversion net other end is connected with transition net one end, the transition net other end is connected with pocket net one end, the pocket net other end seals and forms the pocket bottom, the transition net all is equipped with the reinforcing ring with the junction of pocket net, leading water conservancy diversion net, the mesh size of pocket net is a, the mesh size of transition net is b, the mesh size of leading water conservancy diversion net is c, then a is not more than b and is less than c.
The pocket net is made of double-layer net sheets.
The front flow guiding net is in a trapezoid shape, and the smaller end of the front flow guiding net is connected with the transition net.
The flaring ring and the reinforcing ring are respectively composed of a floating rod, a sinking rod and side rods, wherein the floating rod is made of light materials, two ends of the floating rod are respectively connected with one side rod, and the other ends of the two side rods are downwards connected with the sinking rod.
The transition net is in a trapezoid shape, and the larger end of the transition net is connected with the front flow guiding net.
After the scheme is adopted, the flaring ring is used for flaring the net opening of the front diversion net to facilitate the entry of floaters on the water surface, the floaters enter the front diversion net and then pass through the transition net to enter the pocket net, the pocket net is collected through the pocket net, the pocket net is made of small-mesh net pieces to prevent the entered floaters or garbage from being washed out by water, the reinforcing ring is used for flaring the transition net and the pocket net to prevent the transition net and the pocket net from being knotted or distorted in the water, and meanwhile, the front diversion net, the transition net and the pocket net are always linearly distributed along the water flow direction under the driving of the impact of the water flow; the floating rod is used for providing buoyancy for the reinforcing ring, so that the top of the transition net floats on the water surface, and the flaring ring semi-floats on the water surface through the external pull rope (the sinking rod is positioned underwater, the floating rod is positioned above the water surface, and one half of the side rod is positioned underwater), so that the floating objects (garbage) on the water surface smoothly enter the front diversion net. Rational in infrastructure, excellent in use effect after this scheme of adoption.
