When the vacuum pump (2-2) pumps air in the vacuum shell (2-1), water enters the vacuum shell (2-1) under the action of negative pressure; and (3) closing the water inlet pipe valve (2-5), opening the water outlet pipe valve (2-6), and impacting the blade (1-2) by water so as to drive the generator (1-1) to generate electricity. The method can pump the water in the low-level water pool (3) to a high position, and has good power generation effect and high cost performance.
Description
The first, the field:
the invention relates to a generator for generating electricity by water head difference.
Secondly, background art:
the existing hydroelectric generation is that a generator is arranged at the lower part of a water level by means of natural water level difference, water impacts blades to rotate, the blades drive the generator to rotate, and the generator generates electricity. Because the water level difference is not in many places, and meanwhile, the water flow needs to be continuously supplied, the rain can only be rained in the day. This form of power generation has limited power generation and is therefore relatively cost effective.
Thirdly, the invention content:
the invention aims to solve the problems that: the power generation is not influenced by water level difference and weather, and the cost performance is very high.
In order to solve the problems, the working principle of the low-voltage high-level generator is as follows: pumping out air in the vacuum shell to form negative pressure; then, a valve on the water inlet pipe is opened, and water with a lower water level is sucked into the vacuum shell from the water inlet pipe under the action of negative pressure; then the valve on the water inlet pipe is closed, the valve on the water outlet pipe is opened, the water in the vacuum shell flows out from the water outlet pipe and impacts on the blade which is low from the vacuum shell and is connected with the generator, so that the blade rotates to drive the generator to generate electricity. In the process, as the density of the water is eight-to-many times that of the air, the work of sucking the air to form negative pressure in the vacuum shell is less, and the power generated by the water entering the vacuum shell and rushing down from the vacuum shell is relatively large. According to the working principle, the technical scheme is as follows: the vacuum pump is used for pumping the air in the vacuum shell to form negative pressure in the vacuum shell, then the valve of the vacuum pump before entering the vacuum shell is closed, the valve of the water inlet pipe before entering the vacuum shell is opened, the other end of the water inlet pipe enters the water in the pool, and the other end of the water inlet pipe is connected with the vacuum shell, at the moment, the water in the pool flows into the vacuum shell along the water inlet pipe under the action of the negative pressure until the pressure in the vacuum shell is equal to the atmospheric pressure, a large amount of water exists in the space in the vacuum shell, and only a small amount of air exists; at this time, the valve installed on the water inlet pipe is closed; then a valve on a water outlet pipe connected with the vacuum shell is opened, water in the vacuum shell can be flushed into a shell below along the water outlet pipe and impact on a blade connected with the generator, and the blade rotates under the action of impact force and drives the generator to rotate to generate electricity. In the process, certain energy is needed for pumping out the air in the vacuum shell, but the space of the vacuum shell can be nearly filled, and meanwhile, the vacuum shell has certain height, so the generated kinetic energy is larger.
After the method is adopted, a large amount of electric energy can be generated because less energy is used for pumping water to a high position; meanwhile, the device is not influenced by water head difference and weather, and the cost performance is very high. It not only generates electricity better than current hydroelectric generation device, simultaneously, it can be based on the demand condition confirms what of generated energy. The water conservancy power generation device has higher cost performance than the existing water conservancy power generation device, and also has higher cost performance than the power generation devices of coal, fuel, wind power, solar energy and other power generation modes. It can be made small or large.
