In the aforementioned filter structure for a hydropower station, a connecting rod is connected between the reinforcing rod and the supporting column, and the connecting rod is vertically connected to the reinforcing rod, so as to further improve the overall structural strength.

In the aforementioned filter structure for hydropower stations, arc-shaped buffer plates are connected to the sides of the support columns, and the buffer plates are located between two filter screens.

In the above-mentioned filter structure used in hydropower stations, the top of the filter screen is also connected with an obliquely arranged baffle.

Compared with the prior art, the utility model designs a filter structure for hydropower stations, which filters the garbage by setting two filter screens distributed in a "V" shape, and at the same time makes the garbage flow along the filter screen when filtering. The two sides move to the garbage interception net, which can filter the garbage and concentrate the garbage at the same time. It is convenient for workers to directly use the fishing net to pick up and remove the garbage in the garbage interception net on the shore. It does not need to be cleaned in the water. The hydropower station needs to be shut down to avoid affecting normal power generation, and it has good safety and high garbage removal efficiency. In addition, the utility model sets the garbage interception net into a "U" shape, which can concentrate the garbage in the middle of the "U"-shaped garbage interception net, which further facilitates the centralized removal of garbage and improves the removal efficiency; by setting the fixed rod, slider, The chute and electric hoist can adjust the position of the filter according to the height of the water surface, improve the efficiency of garbage interception, and improve the effect of garbage removal; by setting fixed rods, reinforcing rods and connecting rods, the structural strength of the overall structure can be improved to prevent being Garbage is washed away and affects the removal of garbage; by setting the buffer plate, the garbage can be buffered to prolong the overall service life; by setting the baffle, the garbage can also be blocked at the top of the filter to prevent the garbage from crossing the filter, further improving the garbage collection efficiency. Clear effect. Therefore, the utility model can not only avoid affecting normal power generation, but also has the advantages of good safety, high garbage removal efficiency, good garbage removal effect, good structural strength and long service life.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the utility model.

Example. A filter structure for a hydropower station, composed as shown in Figures 1 to 3, including a support column 1, and both sides of the support column 1 are provided with a filter screen 2 and a column 3; the two sides of the filter screen 2 are respectively connected to the support column 1 is connected to the column 3, and the two filter screens 2 are distributed in a "V" shape; one side of the column 3 is also provided with a garbage intercepting net 4.

The garbage intercepting net 4 is in the shape of "U"; the filter screen 2 is a square hard filter screen, and the top, bottom and side edges of the filter screen 2 are connected with fixed rods 5; A slider 6 is connected to the fixed rod 5 on one side of the column 3, and a chute 7 corresponding to the slider 6 is provided on the column 3; an electric hoist 8 is provided on the top of the column 3, and the electric hoist 8 is connected to the The fixed rod 5 that slide block 6 is arranged connects; Described 2 upright posts 3 are provided with reinforcing rod 9, and the two ends of reinforcing rod 9 are respectively connected with the fixing rod 5 of 2 outer sides of filter screen 2; Described reinforcing rod 9 and the support column 1 are connected with a connecting rod 10, and the connecting rod 10 is vertically connected with the reinforcing rod 9; the side of the support column 1 is connected with an arc-shaped buffer plate 11, and the buffer plate 11 is located between the two filter screens 2 Between; the top of the filter screen 2 is also connected with an inclined baffle 12 .
