Description

Still water power generation technology

Technical Field

The invention relates to the technical field of water conservancy facilities, in particular to a method for improving the traditional defects and improving the generating efficiency of a hydropower station under the condition of no water level fall.

Background

At present, the conventional hydroelectric generation mainly utilizes the potential energy of water flow at high positions of rivers, lakes and the like to flow to low positions, converts the potential energy stored in the water flow into mechanical energy of a water turbine, and then uses the water turbine as power to drive a generator to generate electric energy. The process is that the potential energy of water is converted into mechanical energy and then into electric energy. In the process of hydraulic power generation, the conversion of potential energy of water into mechanical energy and the conversion of mechanical energy into electric energy can generate large energy loss, and the energy conversion rate of hydraulic power generation and the energy utilization rate of hydraulic energy are low.

With the progress of science and technology, the technology of conventional hydraulic power generation is mature day by day, and the energy loss of each link of hydraulic power generation is reduced to a great extent, but the energy loss of conventional hydraulic power generation cannot be completely eliminated.

Meanwhile, the comprehensive utilization rate of the hydroenergy serving as renewable clean energy is improved, and the method has important significance for meeting the increasing energy demand of the human society, relieving the decreasing current situation of non-renewable energy sources worldwide and reducing pollution generated in the process of using fossil energy.

Detailed Description

The technical solutions of the present invention will be described in detail and fully with reference to the accompanying drawings in the following embodiments, wherein the described embodiments are only a part of embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person skilled in the art without making creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

A device for converting pressure in deep water; comprises 7, a lower cover; 1. an upper cover; 3. the two piston cylinders 8 are arranged in two large holes of the lower cover 7 and tightly connected, the two gravity type piston shafts 15 are sleeved in the piston cylinders 8 to reciprocate up and down oppositely, the driving rod 19 is used as a movable connecting body between the gravity type piston cylinders 8 and the connecting rod 2, both ends of the movable connecting body are provided with sealing bearings 4, the driving wheel 18 is provided with two opposite holes which are fixedly and precisely connected with the connecting rod 2, the driving rod 19 and the gravity type piston shafts 15 are driven to reciprocate by rotating around the middle hole, a supporting structure formed by a supporting rod 17 and a supporting frame 16 is arranged between the driving rod 19 and the gravity type piston shafts to support, and the inertia wheel 6 is fixedly connected with the connecting rod 2.

Starting the method; the external water outlet 13 is blocked by water with a certain height, the external water outlet 13 is provided with a check valve, the water cannot flow into the pressure bearing chamber 14, the two external water inlets 10 are connected with a reservoir with the same height, the water level of the external water outlet 13 is equal to that of the external water inlets 10, at this time, a z-shaped starter is used for rotating to drive a starting connecting shaft in the sealing cover 5 to rotate, the driving wheel 1 and the connecting rod 2 rotate to drive the gravity type piston 15 to reciprocate up and down, when the gravity type piston 15 has a piston moving upwards at the bottom, a negative pressure is formed, and the water in the external reservoir 20 flows into the pressure conversion chamber 12 from the drainage pipeline 21 because the pressure is greater than that of the pressure conversion chamber 12. Because the external water inlet 10 is provided with the check valve, water can not flow back, at the moment, the water enters the piston water outlet 9 through the internal water inlet 11 and enters the pressure bearing chamber 14 due to inertia formed by the gravity type piston shaft 15 and the inertia wheel 6 together, the check valve is arranged between the piston water outlet 9 and the internal water inlet 11, and one cycle is completed, so that the piston is continuously moved under the pressure of external water, the pressure in the pressure bearing chamber 14 is continuously increased, water is also continuously increased, the water is forced to flow to the reservoir 20 from the external water outlet 13, the hydraulic generator 22 is pushed to generate electricity, and the potential energy of the water can be infinitely recycled.

A technical principle; check valve 26 when water enters the u-shaped pipe from water inlet 23 to check valve 25 because 27 is a high pressure area

The valve is closed, water enters the check valve 25 to reach the water outlet 24 due to atmospheric pressure balance, a heavy object can be pushed upwards to reach the water outlet 24 due to the pushing force, when the water reaches the water outlet 24, the water outlet 24 is connected with the high-pressure area 27 at the moment, the liquid level of the water outlet 24 has a liquid level difference with the liquid level 28 of the high-pressure area 27 due to the internal pressure balance, the heavy object which has no resistance due to gravity falls downwards from the liquid level 24 to reach the check valve 25, the water flows into the high-pressure area 27 through the check valve 26, and the pressure difference increased by the high-pressure area 27 is deduced to be equal to the volume of the increased water according to the Boyle-Mary specific formula, namely:

P1-P = V (liquid increase)

The volume of the neutralizing liquid is obtained by the formula:

H=(P1-P)/S

h in the formula is the minimum height that water can be pushed to at a single time under the action of the gravity piston shaft and the inertia wheel under the standard atmospheric pressure.
