Description

River channel interception system

Technical Field

The utility model relates to a reservoir face management facility, especially a river course interception system under pumped storage power station.

Background

A hydropower station of Zhang gulf in Hebei is a pumped storage power station which is provided with an upper reservoir and a lower reservoir (pond), and when the water flow in the upper reservoir flows to the lower reservoir, the potential energy of the consumed water is converted into electric energy like a conventional hydroelectric power station; conversely, when water in the lower reservoir is conveyed to the upper reservoir, water is pumped for energy storage, and consumed electric energy is converted into potential energy of the water. The energy storage device has the functions of absorbing electric energy in a power grid during the period of low-ebb load, pumping water to an upper reservoir and accumulating energy; and during peak load, the load at peak is born by the pumped storage unit, so that the load of the conventional unit does not need to be increased to Pmax, and the pumped storage power station: the method has the advantages that (1) the peak regulation effect is realized on a power grid, and the fuel consumption, the plant power consumption and the operation cost of a thermal power unit can be reduced; (2) the utilization rate of the thermal power generating unit is improved, and the installed capacity of the thermal power generating unit can be reduced; (3) the contradiction between the hydropower generation and the agricultural water utilization can be avoided, and the dispatching can be performed according to the requirements of the power grid under certain conditions. The importance of the pumped storage power station is self-evident, but the workload of managing and maintaining the lower reservoir surface with wide area is also quite large, the lower reservoir of the bay hydropower station in the north of the river is communicated with the upstream river channel, a large amount of floating objects flow into the lower reservoir along with rainwater through the river channel in rainy seasons, the normal production of the power station is threatened, and a large amount of manpower and material resources are consumed for cleaning; in addition, the lower reservoir is communicated with an upstream river channel and is often invaded by ships driven by foreign persons, so that the interference on normal production activities of the power station is brought, and the lower reservoir is in danger due to the existence of a high-risk area unknown by the foreign persons.

At present, floaters which flow into a lower reservoir in rainy season are cleaned in a manual cleaning mode in Zhang river gulf hydropower station in Hebei river; the method is original and the means is passive, and the ship which secretly runs into the storage area is also sent out security personnel to be forcibly driven away.

Disclosure of Invention

An object of the utility model is to provide a river course interception system installs reservoir and the intercommunication department in the upper reaches river course under the pumped storage power station, when the reservoir under the admission upper reaches incoming water gets into, prevents surging of floater and external ship entering.

The technical scheme of the utility model as follows:

a river channel interception system is composed of a stainless steel wire rope, a plastic floating barrel, vertical constructional columns arranged on two adjacent banks of a river channel, a sliding support and stainless steel supporting wheels, wherein the sliding support is of an annular structure, the stainless steel is manufactured, and the shape of the inside of the outside of the vertical constructional columns arranged on two adjacent banks of the river channel is matched with the shape of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the outside of the inside of the; the stainless steel supporting wheels are uniformly arranged in the sliding support in an annular shape, and the supporting sliding support is sleeved outside the vertical constructional column and can flexibly move up and down; the stainless steel wire ropes are 2 and arranged in parallel, and two ends of the stainless steel wire ropes are tied on a sliding support which takes vertical constructional columns arranged on two adjacent bank sides of a river channel as guide rails; the plastic floating barrels are respectively and uniformly distributed and fixed below 2 parallel stainless steel wire ropes and a sliding support which takes vertical constructional columns arranged on two sides of an endangered river channel as guide rails. The river channel intercepting system is arranged at the communication position of the lower reservoir of the pumped storage power station and the upstream river channel, and can prevent floating objects from entering and foreign ships from entering while upstream incoming water is allowed to enter the lower reservoir.

The utility model discloses a river course interception system is when setting up under the bridge of strideing across the river course, and the constructional column is put as the perpendicular of putting at both ends to the existing pier of preferred use bridge and builds.

The utility model discloses a plastics floating bucket in the river course interception system is preferred with the great colour of surface of water colour contrast to clearly warn being close to personnel and ship.

The utility model provides a river course interception system, reasonable in design, easy installation are built, can go up and down along with the lift of water level in the use, float on the surface of water all the time, and the not high investment of construction cost has solved the pumped storage power station of puzzlement managers always under reservoir face management problem promptly. The floating device is arranged at the communication position of the lower reservoir of the pumped storage power station and an upstream river channel, can prevent the inflow of floaters and the entrance of foreign ships, saves the cost for cleaning the floaters and security, and has great significance for the management of the lower reservoir surface of the pumped storage power station.
