Description

Technical Field

[0001] The invention relates to the field of hydropower stations, in particular to a sewage interception system for a water inlet of a hydropower station. Background Art

[0002] A hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. It is widely built and put into use because of its advantages such as green energy saving. In the process of power generation, a hydropower station uses the impact of upstream water flow to drive the generator set to rotate to achieve power generation. However, the upstream water flow often carries a large amount of garbage into the interception area of ​​the reservoir. In order to prevent garbage from entering the water inlet, a trash rack is generally set at the water inlet. The intercepted debris will float and accumulate on the trash rack, and it is necessary to rely on manual methods to salvage and clean up the floating debris. This is not only time-consuming and labor-intensive, and inefficient, but the slow manual salvage speed will also affect the water intake. Therefore, if an automatic salvage device can be developed, the salvage efficiency can be greatly improved. Summary of the invention

DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] Embodiment. The sewage interception system at the water inlet of a hydropower station is composed of Figure 1 As shown, it includes columns 1 located on both sides of the water inlet end of the hydropower station, a trash rack 2 is arranged between the two columns 1, and a semicircular trash rack 3 is arranged on the front side of the trash rack 2; a traveling vehicle 4 is arranged on the upper end of the semicircular trash rack 3, and an inner flap 5 and an outer flap 6 are respectively arranged at the inner and outer ends of the traveling vehicle 4, and an outer flip drive motor 7 matched with the outer flap 6 and an inner flip drive motor 8 matched with the inner flap 5 are respectively arranged in the middle of the inner and outer sides of the traveling vehicle 4; the upper end of the inner side of the inner flap 5 is rotatably connected to the center position of the trash rack 2.

[0015] The outer side of the outer flap 6 is provided with a vertically distributed outer scraper 9, and the upper end of the outer scraper 9 is provided with an outer screw drive module 10 fixed on the outer flap 6. The outer screw drive module 10 is used to drive the outer scraper 9 to move along the outer flap 6 from the outside to the inside.

[0016] The inner side of the inner flap 5 is provided with a vertically distributed inner scraper 11, and the upper end of the inner scraper 11 is provided with an inner screw drive module 12 fixed on the inner flap 5, and the inner screw drive module 12 is used to drive the inner scraper 11 to move along the inner flap 5 from the inside to the outside.

[0017] like Figure 2 As shown, the traveling vehicle 4 is also provided with a garbage collection box 13, the inner flap 5 and the outer flap 6 are located at the inner and outer sides of the middle of the garbage collection box 13, and the inlet of the garbage collection box 13 is flush with the inner flap 5 and the outer flap 6 in a horizontally flipped state.

[0018] The inner flap 5, the outer flap 6, the inner scraper 11 and the outer scraper 9 are all provided with water filtering holes; the side wall surface and the bottom surface of the garbage collection box are also provided with water filtering holes.

[0019] The diameter of the semicircular trash rack corresponds to the width of the trash rack.

[0020] The traveling vehicle is a vehicle with a self-moving function, including a driving wheel, a driven wheel and a vehicle body. A guide rail is provided on the upper surface of the semicircular trash rack, and a slide seat is provided on the lower surface of the vehicle body, so that the traveling vehicle can move along the guide rail.

[0021] A central axis is provided in the middle of the upper end of the trash rack, a rotating set is sleeved on the central axis, and the rotating set is connected to a rotating shaft located at the upper inner end of the inner flap, so that the inner flap can be turned around the rotating set, and the inner flap can also rotate around the center of the trash rack driven by the traveling vehicle.

[0022] Both ends of the garbage collection box are provided with discharge gates. Both ends of the bottom of the garbage collection box are provided with hydraulic rods, and the hydraulic rods are rotatably connected to the garbage collection box, so that unloading in two directions can be realized.

[0023] The operation process of the present invention is as follows: first, the larger garbage is blocked by the semicircular trash rack, and the smaller garbage will enter through the semicircular trash rack and finally be intercepted and blocked by the trash rack. The blocked garbage will be accumulated in the corresponding areas of the semicircular trash rack and the trash rack. The traveling vehicle moves regularly, driving the inner flap to rotate around the center of the trash rack, and driving the outer flap to move accordingly, pushing the intercepted garbage in the corresponding area to one end, and then the inner flap and the outer flap flip toward the garbage direction, so that the garbage in the area is salvaged from the water surface and flush with the feed port of the garbage collection box, and then the outer screw drive module drives the outer scraper to move inward, pushing the garbage on the upper surface of the outer flap into the garbage collection box, and the inner screw drive module drives the inner scraper to move outward, pushing the garbage on the upper surface of the inner flap into the garbage collection box, completing a garbage salvage. Subsequently, the inner and outer flaps are reset to a vertical state, and the inner and outer scrapers are also restored to their original positions. The traveling vehicle moves in the opposite direction, driving the outer and inner flaps to move. After moving to the other end, the inner and outer flaps rotate in the opposite direction to a horizontal and flush state, and the garbage is cleaned and pushed into the garbage collection box through the inner and outer scrapers.

[0024] When the garbage collection box is filled to a certain extent, the discharge gate in the corresponding direction opens, and the hydraulic rod in the opposite direction extends, causing the garbage collection box to tilt and discharge.
