Description

Grab bucket type trash remover for hydroelectric engineering trash rack

Technical Field

The utility model relates to a hydraulic engineering technical field that decontaminates specifically is a hydroelectric engineering trash rack is with grab bucket formula trash cleaning machine.

Background

The trash rack is composed of a frame, a transverse partition plate and grid bars (see the figure, the trash rack is supported on a concrete pier wall and is generally made of steel, the distance between the grid bars depends on the size and the quantity of dirt and the application requirement, the distance between the grid bars for a hydropower station depends on the type and the size of a water turbine so as to ensure that the dirt passing through the trash rack cannot be clamped in a water turbine flow passage part, a trash rack is not arranged in a drainage tunnel and a drainage hole, the trash rack is not arranged in the drainage tunnel and the drainage hole, the diameter or the diameter of the tunnel is not large, when more sunk wood needs to be arranged, the distance between the grid bars is increased, the trash rack is subjected to load, the load is mainly water load formed by water head difference in front and back of the trash rack after the trash rack is blocked, the water load is generally considered according to 2-4 m water head, the size of the grid surface of the trash rack is determined by the flow rate of the trash rack and the allowed flow rate of the trash rack, the trash rack flow rate is reduced and the trash rack is convenient to be cleaned, the trash rack flow rate The semicircle fold line shape can be vertical or inclined on the vertical surface, and is determined according to the nature, the amount, the application requirement and the cleaning mode of the dirt carried by the water flow. The water inlet of the dam type hydropower station with a higher water head is usually in a vertical semicircular shape, and the water inlet gate, the hydraulic tunnel and the water delivery pipeline are in a multi-purpose linear shape. The height of the trash rack of the deep water inlet is related to the reservoir water level and the trash removal mode. The top elevation of the water tank is slightly higher than the flood control limit water level (see the characteristic value of the water tank) when the water tank does not need to be cleaned frequently, and the top elevation of the water tank is higher than the highest water level when the water tank needs to be cleaned frequently. The trash rack with larger height can be made into a plurality of sections, and the size of each section can be determined according to the lifting capacity. In winter in cold areas, anti-freezing measures are required to be taken for the trash rack. The common method comprises the steps of passing low-voltage (50V) current to the trash rack, utilizing self resistance heating of a metal structure to prevent freezing, is simple and convenient, but has high power consumption, utilizing compressed air to bring water with higher temperature at the lower layer of the reservoir to the water surface under the water surface in front of the trash rack, and maintaining the water not to freeze in a range in front of and behind the trash rack, so that the method is mainly used for large-scale reservoirs. The dirt can be cleaned manually or by a dirt cleaner. The depth of the manual decontamination is shallow, and is generally not more than 5 m. When the trash rack is located deep underwater, the trash cleaning machine is used for cleaning trash, and if necessary, two trash racks can be arranged, when the trash needs to be cleaned, the spare trash rack is placed into the access door groove, and then the working trash rack is lifted out for cleaning.
