A pontoon type waterproof curtain device

Abstract

The invention discloses a floating bridge type waterproof curtain device. The floating bridge type waterproof curtain device is applied to the field of water conservancy and hydropower. The device is composed of a waterproof curtain, a firm pier, a floating bridge structure and a winding and unwinding device. The waterproof curtain comprises multiple layers of non-woven geotextile, upper steel, lower steel and a limiting buckle; the firm pier is of a concrete solid structure, and a cable penetrating hole is reversed in the upper end of the firm pier; the floating bridge structure comprises a floating bridge cable, a floating ball, a floating ball connecting cable and a floating ball connecting cable winding machine; and the winding and unwinding device comprises a main cable, a main cable winch, a winding and unwinding cable, a pulley and a winding and unwinding cable winch. The device has the beneficial effects that firstly, the floating bridge type waterproof curtain structure has the good adaptability, the curtain device can be suitable for different water levels and different running stations at the same time, and manpower and material resources are saved; through a shore operation winch, downward transferring and winding of the curtain can be achieved, and convenience is brought to curtain mounting and maintenance replacement; and the flexible waterproof curtain is cheap, mounting and recycling are convenient, the electric quantity is not lost while the draining water temperature is improved, and the cost is saved.

Description

technical field [0001] The invention discloses a pontoon-type water-proof curtain device capable of increasing the temperature of water discharged from a hydropower station, which is applied to the field of water conservancy and hydropower. Background technique [0002] High dam reservoirs have good regulating performance. Due to their large storage capacity and slow flow velocity, obvious temperature stratification will appear at the turn of spring and summer. However, due to the low elevation of the discharge outlet required by the hydropower station for power generation, the outlet water temperature of the reservoir is lower than the water temperature of the natural river, causing changes in the water temperature of the natural river below the dam, which will affect the water quality and ecology of farmland irrigation, industrial water supply, domestic water, and downstream rivers. It will have adverse effects on the balance of water and the utilization of water in the re...

Problems solved by technology

However, due to the low elevation of the discharge outlet required by the hydropower station for power generation, the outlet water temperature of the reservoir is lower than the water temperature of the natural river, causing changes in the water temperature of the natural river below the dam, which will affect the water quality and ecology of farmland irrigation, industrial water supply, domestic water, and downstream rivers. adverse effects on the balance of water in the reservoir area and the use of water in the reservoir area

[0003] At present, there are many schemes for the prevention and control of low-temperature water discharged from the power station, mainly including low-temperature water interception dam, shore tower water inlet layered water intake, reinforced concrete wall, stacked beam door layered water intake and other schemes, such schemes are limited to those under construction Or unbuilt projects, but it is not suitable for high dams and large reservoirs that have been in operation. The main reason is that during the construction process, the reservoir needs to be emptied to complete the construction. Huge economic losses related to irrigation water

In addition, the traditional layered water intake method requires structural control at all times, which consumes a lot of manpower and material resources
