A kind of rotary hinge type dirt blocking and drifting

Abstract

The invention discloses a rotary hinge type drain grating floating gate and belongs to the technical field of water and electricity drain grating. The rotary hinge type drain grating floating gate comprises a connecting frame, a drain grating frame, a drain grating gate body, a floating body, a first hinge and a second hinge. One end of the connecting frame is connected to the outer wall, on the two sides of a water inlet of a power station or the two sides of a water inlet of a dam, of a gate pier. The other end of the connecting frame is connected with the drain grating frame through the second hinge. The drain grating gate body and the floating body are arranged on the drain grating frame. When the water level of the water inlet position changes, the drain grating frame has the self-floating capacity as a whole due to the floating body, the drain grating frame is capable of being self-adaptive to the changes of the water level of the water inlet through hinge connection, and the drain grating gate body has the drain grating function, so that the rotary hinge type drain grating floating gate can effectively block floating debris at the water inlet and suspended debris within a certain distance from the water surface.

Description

technical field [0001] The invention relates to the technical field of hydropower pollution prevention, in particular to a hinged type pollution prevention and floating drainage. Background technique [0002] The trash arresting device of the hydropower station installed at the water inlet of the hydropower station is an indispensable device for the hydropower station. The existing trash arresting devices generally include flat fixed trash racks and self-floating trash racks. Plane fixed trash racks are generally fixed at the water inlets of hydropower stations. On rivers with a lot of floating debris, a large amount of dirt in front of the racks will accumulate at the water inlets. If they are not cleaned in time, the grid holes will be blocked, affecting water diversion and power generation efficiency. The self-floating trash blocking and floating row is usually set at the front of a certain water area in front of the water inlet. The floating body and the grid are flexib...

Problems solved by technology

Plane fixed trash racks are generally fixed at the water inlets of hydropower stations. On rivers with a lot of floating debris, a large amount of dirt in front of the racks will accumulate at the water inlets. If they are not cleaned in time, the grid holes will be blocked, affecting water diversion and power generation efficiency

The self-floating trash blocking and floating row is usually set at the front of a certain water area in front of the water inlet. The floating body and the grid are flexibly connected in series through a steel wire rope, floating on the water surface, and both ends are fixed, but generally a distance of hundreds of meters is required. In order to ensure the stability of use, and the cost is high. When the water level of the hydropower station changes, it is usually necessary to use human winches or electric motors to lift and lift, and set up a monitoring water level system to realize the change of the floating row with the water level. The labor intensity of the manual method is high. , high cost, poor real-time performance and reliability, poor pollution blocking effect
