Ecological hydropower station for river regulation

Abstract

The invention relates to an ecological hydropower station for river regulation. The ecological hydropower station comprises a dam body which is arranged in the river width direction and divides the river into an upstream section and a downstream section; protection dam bodies are oppositely disposed on the two sides of the upstream section; a net-shaped obstacle removing device is disposed above the inlet end of a drainage channel; a sedimentation trough and a motive power trough are formed in the sides, which are far away from each other, of the two protection dam bodies correspondingly; thenet-shaped obstacle removing device is connected with the middle of the sedimentation trough and used for collecting small-particle obstacles; a transmission device is disposed in the motive power trough; a tubular obstacle removing device is disposed above the net-shaped obstacle removing device; a floating obstacle stop device is disposed on the upper side of a sand stop dam; the inclination angle of the floating obstacle stop device changes along with change of the water level of the river; a second water wheel is disposed on the upper side of a tail water opening, the wheel edge of the lower end of the second water wheel is in contact with water discharged out of the tail water opening and performs acting; and the second water wheel is in transmission connection with the transmission device through a transmission shaft. By means of the hydropower station, the hydroenergy is fully utilized for self-purifying a water body, and ecological regulation of the river can be achieved.

Description

technical field [0001] The invention relates to the technical field of hydropower stations, in particular to an ecological hydropower station used for river channel regulation. Background technique [0002] A hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. At present, the power stations installed in the river are mainly some large hydropower stations, such as Shanxia Hydropower Station and Gezhouba Hydropower Station. These hydropower stations are mainly used for power supply in urban life, industry and other fields. In some remote rural areas, power is still supplied by small power stations. The diversion canals of these hydropower stations often flow around rural households, so the water bodies are easily polluted. This year, due to the country's stricter requirements for water environmental protection, and with the construction of more and more large-scale power stations, small hydropower stations that poll...

Problems solved by technology

At present, the power stations installed in the river are mainly some large hydropower stations, such as Shanxia Hydropower Station and Gezhouba Hydropower Station. These hydropower stations are mainly used for power supply in urban life, industry and other fields. In some remote rural areas, power is still supplied by small power stations. The diversion channels of these hydropower stations often flow around rural households, so the water bodies are prone to pollution

This year, due to the country's stricter requirements for water environmental protection and the construction of more and more large-scale power stations, small hydropower stations that pollute water bodies have been closed in many areas, although this can reduce some rivers. However, since the river often flows through areas such as forests, domestic garbage, leaves, driftwood and other floating objects will float on the surface of the water body in the river, and sediment from the upstream area will also be entrained in the water body of the river, especially in rainy days. , the soil erosion in the upper reaches is more serious. If the domestic garbage, leaves, and dead branches in the river cannot be removed in time, they will flow from the river to the river, and then from the river to the sea. Especially in some coastal cities, a large amount of water will be needed at the mouth of the sea. To solve these problems, it is still necessary to clean up the floating objects in the river from the source, and to purify the river water flowing into the river, so as to reduce the purification treatment in downstream areas. input
