Description

Technical Field

[0001] The utility model relates to the technical field of pollution interception devices, in particular to a pollution interception device for a pumped storage power station. Background Art

[0002] A pumped storage power station is a special type of hydropower station, which is mainly composed of an upper reservoir, a lower reservoir, a water transmission system and a power plant. When the power load is low, it uses the excess power of the power grid to pump water from the lower reservoir to the upper reservoir for storage; when the power load is peak, the water in the upper reservoir is released to drive the turbine to generate electricity, thereby regulating the supply and demand balance of the power grid, ensuring the stability of the power system, and improving the operation efficiency of the power grid. Pumped storage power stations have the characteristics of rapid start-up, flexible operation, and large energy storage capacity. They are important peak-shaving, frequency regulation and backup power sources in the power system.

[0003] Corresponding pollution-blocking devices are usually installed at the pumping inlet of a pumped-storage power station. Such pollution-blocking devices can effectively block various debris in the water to prevent these debris from entering the inner wall of the pumping device, thereby avoiding blockage. However, there is a more prominent problem with the existing pollution-blocking devices, that is, it requires operators to go into the water to clean them at a certain period, and this process is extremely dangerous and poses a serious threat to the life safety of the operators.

[0025] A pair of "L"-shaped plates 16 are arranged on the top of the main frame 1, and the two "L"-shaped plates 16 are respectively located on both sides of the gate slot 13. A pair of mounting plates 15 are symmetrically installed on the side walls of the main frame 1, and the two mounting plates 15 are respectively located below the two "L"-shaped plates 16, and a driving assembly 2 is arranged between the "L"-shaped plate 16 and the mounting plate 15 on the same side. The driving assembly 2 includes a lead screw 21 movably installed between the "L"-shaped plate 16 and the mounting plate 15, one end of the lead screw 21 is connected to the transmission end of the motor 20, and the motor 20 is installed at the bottom of the mounting plate 15;

[0026] The main frame 1 has movable grooves 14 symmetrically formed on both sides thereof, and the movable grooves 14 are located between the "L"-shaped plate 16 and the mounting plate 15. The gate 3 has driving members 30 symmetrically formed on both sides thereof, and the driving members 30 are located in the movable grooves 14 and are threadedly mounted on the lead screw 21.

[0027] Two support members 5 are symmetrically installed on the outside of the two traction devices 4, and a pulley 50 is movably installed in the support member 5. A pair of through holes 17 are opened on the top of the main frame 1, and the two through holes 17 are respectively located on the outside of the two support members 5. The traction rope of the traction device 4 is installed on the pulley 50, and its end passes through the through hole 17 and is arranged in the main frame 1. A hook 40 is installed at the end of the traction rope. Both ends of the dirt loading frame 6 are provided with a hook 61, and the two hooks 40 are hung on the two hooks 61 respectively;

[0028] As an optimization solution of the present invention, by providing the traction device 4, it is convenient to lift the dirt loading frame 6, which is convenient for subsequent cleaning without the need for personnel to go into the water for operation, thereby improving safety and convenience.

[0029] As an optimization solution of the present invention, by providing a pulley 50, the traction action of the traction rope is made smoother and the friction resistance is reduced.
