Abstract
The utility model discloses a kind of trashrack, comprise limit stainless steel drainage plate (1) that meets water, support frame (2) and multiple stainless steel grid (3); Support frame (2) is rectangular frame, be fixed on the top of catch basin, stainless steel grid (3) is parallel with water (flow) direction to be fixed on support frame (2), limit stainless steel drainage plate (1) that meets water is fixed on support frame (2) near one end of upstream, consistent with overflow weir profile.The utility model makes full use of fluid mechanics principle, ensure that the lower floating thing sluiced in stream can smooth and easyly flow away, adopt stainless steel material, wear-resisting and non-corrosive, there will not be corrosion and the problem that causes resistance to increase, fabrication and installation are simple, reliable, well solve the problem of small hydropower station overflow-type intake blocking.
Description
Technical field
The utility model belongs to miniature hydro-power generation engineering field, is specifically related to a kind of small power station overflow-type intake trashrack device.
Background technology
Small runoff river hydroeclectric power plant does not have reservoir, water inlet is located on overflow weir, the band steel framework that its trashrack adopts many to be arranged in parallel is placed on water inlet, do not establish special trashrack cleaning plant, the cleaning of foreign material relies on overflow to wash away and takes away, and the floating thing such as leaf, weeds can not waft with overflow completely, is easily formed at grid place and assembles, can trashrack be blocked time serious, affect the running of the hydraulic turbine.Be common small hydropower station trash rack for water inlet as shown in Figure 1-2, current flow through from overflow weir, fall into catch basin, through intake pipe diversion to the factory building hydraulic turbine by part current during trashrack; The barrier rib of its trashrack is vertical with water (flow) direction, and floating thing is subject to the stop of grizzly bar and slows down, and easily causes floating thing to assemble, may block intake time serious.
Utility model content
The purpose of this utility model is to provide a kind of trashrack, solves the problem that floating thing is assembled, blocked intake.
The technical solution of the utility model is: a kind of trashrack, is characterized in that: comprise the limit stainless steel drainage plate 1 that meets water, support frame 2 and multiple stainless steel grid 3; Support frame 2 is rectangular frame, is fixed on the top of catch basin, and stainless steel grid 3 is parallel with water (flow) direction to be fixed on support frame 2, and the limit stainless steel drainage plate 1 that meets water is fixed on support frame 2 one end near upstream, consistent with overflow weir profile.
Stainless steel grid 3 is streamlined stainless steel grid, increases angle of slope, and extend to downstream always at afterbody.
Support frame 2 is made for the thick corrosion resistant plate of 5mm; Stainless steel grid 3 stainless steel of diameter 6mm is made; The thick corrosion resistant plate of limit stainless steel drainage plate 1 3mm that meets water is made.
Beneficial effect: the utility model makes full use of fluid mechanics principle, ensure that the lower floating thing sluiced in stream can smooth and easyly flow away, adopt stainless steel material, wear-resisting and non-corrosive, there will not be corrosion and the problem that causes resistance to increase, fabrication and installation are simple, reliable, well solve the problem of small hydropower station overflow-type intake blocking.

Wherein: 1-meet water limit stainless steel drainage plate, 2-support frame, 3-stainless steel grid; 4-trashrack, 5-catch basin, 6-overflow weir, 7-intake pipe; Arrow is water (flow) direction.
Detailed description of the invention
For making the purpose of this utility model, content and advantage clearly, below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.
As seen in figures 3-6, the utility model provides a kind of trashrack, comprises the limit stainless steel drainage plate 1 that meets water, support frame 2 and multiple stainless steel grid 3; Support frame 2 is the rectangular frame that the thick corrosion resistant plate of 5mm is made, by the pre-buried top being fixed on concrete catch basin, stainless steel grid 3 is parallel after being made into streamline shape with the stainless steel of diameter 6mm to be weldingly fixed on support frame 2, the thick corrosion resistant plate of limit stainless steel drainage plate 1 3mm that meets water is made, after the welding completing support frame 2 and stainless steel grid 3, be welded on support frame 2 one end near upstream, form the limit stainless steel drainage plate that meets water, consistent with concrete overflow weir profile, do not cause additional flow-disturbing.
Stainless steel grid 3 is streamlined stainless steel grid, increases angle of slope, and extends to downstream always, to reach the smooth and easy delivery of the rail mounted of floating thing, avoid floating thing to be gathered on trashrack at afterbody, impact water intaking quality and effect.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
