Description

A new type of hydraulic buoyancy and gravity power generation technology device

                      

The invention relates to the theory of hydraulic buoyancy and gravity, and at the same time relates to power generation technology, specifically providing a novel hydraulic buoyancy gravity power generation technology device.

Background technique

Due to its environmental protection, cleanliness and high quality, hydropower is favored in the development of the electric power industry. Especially with the increasing shortage of coal resources required for coal-fired power generation, it is an inevitable choice to vigorously develop hydropower projects. The traditional hydropower projects currently being built generally select areas with hydropower conditions, build reservoir dams, intercept river water flow, and install hydroelectric generating units. This will not only be limited by the conditions of hydropower resources, but will also cause part of the land to be submerged and resettled, which also restricts and affects the scale and speed of the development and construction of hydropower projects to a certain extent. In order to change this situation, it is particularly important to research and develop new operating modes of hydropower projects. As a kind of hydropower resource, hydraulic buoyancy has been widely and maturely applied in ship shipping, but it is still rare to be applied in hydropower engineering. At present, the research and development of hydraulic buoyancy power generation is limited to the use of waves The buoyancy and gravity formed by the ups and downs of the fluctuations are converted to generate electricity. Although this hydroelectric power generation technology has changed greatly compared with the traditional hydroelectric power generation technology using water energy, the power generated by this power generation technology is extremely high. The main reason is that the waves fluctuate and the water head drop is often very small, which makes it difficult to build large-capacity power stations. In addition, power generation in the ocean, because it is far away from the load center, and the long-distance power transmission to the power load center will also cause a substantial increase in construction costs. Therefore, the research and development of new technologies for hydro buoyancy power generation is of great significance for promoting the development of hydropower generation.

Contents of the invention

The purpose of this invention is to provide a new type of hydraulic buoyancy and gravity power generation technology device, which can not only carry out large-scale and large-capacity hydropower generation, greatly reduce the investment per kilowatt of hydropower engineering, but also open up the development and development of water energy. application range.

The object of the present invention is achieved in that a novel hydraulic buoyancy gravity power generation technology device comprises a cylindrical upright water tower, a hydraulic buoyancy gravity generator, a hydraulic buoyancy gravity converter and a generator set. The cylindrical vertical water tower is constructed of reinforced concrete, and its height can be high or low, depending on the capacity of the device. The hydraulic buoyancy and gravity generator is composed of guide wheels, chains, balance inertia driving wheels and protons, and is installed on the inside and outside of the vertical water tower. Stand upright at the bottom of the water tower. The generator set is composed of a transmission, a generator and a coupling, and the generator is connected together through a transmission and a balance inertia driving wheel.

The working principle of this invention is like this: when part of the protons of the hydraulic buoyancy gravity generator are in the water of the vertical water tower, the protons move upwards due to the effect of the hydraulic buoyancy, and the protons outside the vertical water tower move downward due to the effect of gravity. The protons are all fixed on the chain, at this time, the chain will carry out directional circular motion under the guidance of the upper and lower guide wheels, and at this time, the balance inertia driving wheel will rotate at a high speed driven by the chain, so that the generator will rotate generate electricity. When the protons outside the vertical water tower move down to the bottom of the tower under the action of gravity, they enter the negative pressure guide tube of the buoyancy gravity converter, and the protons entering the negative pressure guide tube are under the action of the suction force of the negative pressure guide tube. In addition, under the pull of the protons inside and outside the vertical water tower, they quickly pass through the negative pressure guide pipe and enter the tower from the outside of the tower. The protons entering the tower float from the bottom of the tower to the top of the tower under the action of buoyancy, and then The protons that float up to the top of the tower move quickly to the outside of the tower, and the protons that move outside the tower will move downwards under the action of gravity. In this way, the generator can continue to rotate at a high speed to generate electricity.

In addition, power generation in the ocean, because it is far away from the load center, and the long-distance power transmission to the power load center will also cause a substantial increase in construction costs.
