Problems solved by technology
The original system has the following deficiencies: (1) The overall power generation efficiency of the system is not high, and some energy sources are still not fully utilized; (2) The power generation of the system is unstable and difficult to use
The working principle of this system is basically the same as that of the power generation system of the present invention, but the pressure plate reset method adopts spring reset, the unreliability of power generation and the short life of the spring, thus bringing about the problem of poor economic benefits

The invention provides a mechanical lever type pressure power generation system on an overflow dam. A first-grade step (3), first-grade catchment power generation wells (4), first-grade power generation galleries (6) and a water discharging pipe (16) are sequentially connected. A third-grade step (7), third-grade catchment power generation wells (8), third-grade power generation galleries (10) and the water discharging pipe (16) are sequentially connected. The water discharging pipe (16) and a silt flushing opening (17) are sequentially connected. Each first-grade power generation gallery (6) comprises a large water container, small water containers, a concrete gravity pier (20), a concrete pier base (23), a bearing (21), hinge two-link connecting rods (30), a combined type gear one-way accelerating device (25) and a generator (36), wherein the concrete gravity pier (20) is connected with the concrete pier base (23) and one-way accelerating devices (24) through the bearings (21) and the hinge two-link connecting rods (30) correspondingly. According to the distribution of the water containers of each first-grade power generation gallery (6), the one-way accelerating devices (24) in the middle is connected with the corresponding large water container, and the one-way accelerating devices (24) on the two sides are connected with the small water containers correspondingly.
Description
technical field [0001] The invention relates to hydroelectric power generation technology, in particular to mechanical lever pressure power generation technology on an overflow dam. Background technique [0002] In today's society, the ecological environment is seriously threatened. With the increasing awareness of environmental protection and the stricter emission standards, how to develop new energy has become a common concern in today's society. Pressure energy is ubiquitous in real life, but technologies that convert pressure energy into electrical energy are rare. For water conservancy engineering buildings, the water flow discharged from the high-head discharge structure has huge energy, often reaching tens of millions of kw, while the overflow dam generally simply guides the high-speed discharge water to the downstream of the dam for energy dissipation. The function is single, resulting in a huge waste of water energy, and has certain harm to the dam itself, and the ...
