Description
Technical Field
The invention relates to the technical field of power generation by using river water in mountainous areas, in particular to high-efficiency energy-saving power generation equipment and a power generation method thereof.
Background
Hydroelectric power generation, and scientific technology for researching technical and economic problems of engineering construction, production, operation and the like for converting water energy into electric energy. The water energy utilized by hydroelectric power generation is mainly potential energy stored in water. In order to convert water energy into electric energy, different types of hydropower stations need to be built. The hydroelectric power generation system (hydro electric power) utilizes the water flow with potential energy at high positions such as rivers and lakes to flow to low positions, converts the potential energy contained in the water flow into the kinetic energy of a water turbine, and then uses the water turbine as motive power to drive a generator to generate electric energy. The hydraulic machine (water turbine) is pushed to rotate by utilizing water power (with a water head), the water power is converted into mechanical energy, if another machine (generator) is connected to the water turbine and rotates along with the water turbine, electricity can be generated, and the mechanical energy is converted into electric energy. Hydroelectric power generation is in a sense the process of converting the potential energy of water into mechanical energy and then into electrical energy.
In mountainous areas, especially villages in mountainous areas of Sichuan, the river channels in the mountainous areas are needed to be used for generating electricity in order to supply household electricity to users, and the generated electricity can be used for the users. A dam is constructed in a river channel of a mountain area firstly to accumulate water in the river channel, then hydraulic power generation equipment is installed at the downstream of the dam, during power generation, a sluice in the dam is opened, river channel water enters the power generation equipment, the power generation equipment converts potential energy of the water into mechanical energy, and then the mechanical energy is converted into electric energy, so that the purpose of power generation is achieved.
The existing hydroelectric power generation equipment comprises a casing, a water wheel, a power generation unit, a spray pipe and a drainage channel arranged in the dam, wherein the water wheel is rotatably arranged in the casing, the spray pipe is fixedly arranged on the casing, a water outlet of the spray pipe is inclined downwards to face the water wheel, the other end of the spray pipe is communicated with the water outlet of the drainage channel, a water inlet of the drainage channel is communicated with a river channel positioned on the left side of the dam, the drainage channel is positioned above the spray pipe, a main shaft of the water wheel is connected with an input shaft of the power generation unit through a coupler, and a gate used. During the electricity generation, open the gate, water in the river course passes through drainage channel's entry end, drainage channel's exit end, the entry end of spray tube, spray tube and spray tube exit end in order, sprays the blade of water wheels at last, and spun rivers impact the blade so that water wheels rotate round fixed direction, and the main shaft of water wheels rotates, and the main shaft drives generating set's input shaft and rotates, and generating set's input shaft drives the rotor and rotates, and the rotor cuts magnetic induction line in the stator to finally reach the purpose of electricity generation.
However, although such power generation equipment can generate power, the following defects still exist in practical application: 1. the water flow sprayed from the spray pipe can only impact one surface of the water wheel blade all the time, so that the impacted surface of the blade is quickly eroded and damaged, and the service life of the blade is shortened. 2. The existing blades are usually welded to the body of the water wheel, and when any one blade is damaged, the whole water wheel needs to be replaced, which undoubtedly increases the cost of power generation. 3. When water in the river course gets into drainage channel's entry end, if when having great bulky object in the river course, easily jam drainage channel's entry end, and then lead to unable follow-up electricity generation, in order to solve this problem, can weld at drainage channel's entry end department in advance and separate the net, intercept bulky object through separating the net, although can prevent that bulky object from going on in drainage channel, but separate the net long-term work after, its surface also can cover a large amount of mud and domestic waste, can cause equally to separate the net and block up, use again behind a period unable assurance continue the electricity generation, because the water yield that gets into in drainage channel reduces, and then reduced the generating efficiency. 4. The downstream water falling from the blades after impacting the blades is directly discharged into a downstream river channel, the part of the downstream water still has potential energy and can be used for generating power, however, the part of the downstream water is not well utilized, the potential energy of the water is undoubtedly not fully utilized, and the power generation capacity is further reduced. 5. The main shaft of the water wheel generates a large amount of heat in the rotating process, the heat is directly cooled by water in contact with the water wheel, the heat is not fully utilized, and therefore the heat of the main shaft is wasted. Therefore, a high-efficiency energy-saving power generation device which can improve the power generation amount, improve the power generation efficiency, reduce the power generation cost and fully utilize the heat of the water wheel main shaft is needed.
