technical field

The utility model relates to a device for generating electricity by using water energy, in particular to a device for circulating electricity by using the water energy of circulating quantitative water in a connecting device.

Background technique

At present, there are many ways to generate electricity, such as: thermal power generation, nuclear power generation, wind power generation, solar power generation, hydropower generation and so on.

Thermal power generation is the earliest and most widely used power generation method, but this power generation method needs to consume a lot of non-renewable resources, such as: oil, coal, etc. At the same time, this power generation method will release a large amount of Carbon dioxide has caused serious air pollution.

Nuclear power generation is the cleanest way of generating electricity and will not pollute the air. However, nuclear power generation needs to prevent the leakage of nuclear radiation and deal with nuclear waste. The process is very complicated. Therefore, nuclear power generation has not been widely promoted.

Solar power generation, wind power generation and hydropower generation are environmentally friendly and safe power generation methods. Among them, there are three basic methods of hydropower generation, namely dam-type hydropower generation, diversion-type hydropower generation and hybrid hydropower generation. However, the water energy used by the three methods of hydroelectric power generation is limited to natural artesian water. Whether it is solar power generation, wind power generation or hydropower generation, it is greatly affected by weather, seasons, and geographical environments. Built in areas rich in solar energy, wind energy or hydropower resources; moreover, these three power generation methods, especially solar and wind energy, are difficult to provide continuous and stable power supply.

Although people have been working hard to develop a power generation device that is both environmentally friendly and not limited by natural conditions, there has been no breakthrough progress.

The differential quantitative water cycle power generation device supplements the water source.

The connected and semi-closed differential pressure type quantitative water cycle power generation device described in the utility model applies the water pump and the water turbine respectively in the connected and semi-closed water cycle system, and makes the water pump and the water turbine form a certain height difference to carry out pressure difference work, and utilizes the low water pump The pumping work of the head, with less input energy, makes the work of the turbine obtain greater energy output.

When using the connected semi-closed differential pressure type quantitative water cycle power generation device described in the utility model, firstly open all valves to make the device communicate with each other; then pour water into the outlet pool until the water in the outlet pool and the stilling pool reaches the set Water level line (generally 0.5m from the height of the pool); then turn on the water pump, so that the pumping device will suck the water in the whirling chamber to the outlet pool. At this time, due to the strong centrifugal force and lifting force generated by the variable speed rotation of the impeller when the water pump is working, the water in the whirling chamber will flow at a variable speed, resulting in a sharp drop in the pressure of the water in the whirling chamber on the water in the whirling pipe, making the water in the whirling pipe A state of negative pressure is formed, and the negative pressure sucks the water in the draft tube into the whirling tube so that the draft tube forms a negative pressure suction. Pressure flow causes the water turbine to rotate in the same direction as the water flow to do work. The energy generated by the water turbine is converted into electrical energy output through the generator. flow chamber.
