Description

A device that rotates the sluice shaft of a movable weir to generate hydroelectric power}

The present invention is a sluice gate that can adjust the water level of a river or river by changing the angle of being erected or laid down with a lower end fixed to a concrete structure in a movable beam installed to control the water level of a river or river It relates to a device for rotating the fixed shaft of a movable beam for hydroelectric power generation that can produce electric power by rotating the fixed shaft of the movable beam by the falling hydraulic power falling through it.

In general, in rivers, rivers, or reservoirs, it prevents water pollution of rivers, maintains the underground water level around rivers, protects animals and plants living in rivers, prevents salt damage caused by reverse flow of seawater, and maintains water for transportation and fishing. In order to supply irrigation water used for irrigation and other agricultural work, vertical opening/closing type or rotating movable beams are installed to trap and discharge more than a certain amount of water.

The movable weir blocks the flow of water by a movable panel that acts as a sluice gate so that water is stored during drought, and water can be discharged when the water level rises above a certain level or when it rains.

The device for opening and closing the movable panel of the movable beam generally uses electric energy to drive a motor or operates a hydraulic cylinder to open and close the movable panel, thereby consuming a certain amount of electrical energy for the operation of the movable panel.

In addition to the power source for driving the movable beam switchgear, most of the electrical energy used in daily life and industry is produced by thermal power generation using fossil fuels.

Electric energy is an indispensable energy source that is indispensable for daily life and overall industry, but in order to produce it, in the future, it is faced with the problem of limitations of natural resources and the problems of global warming and environmental pollution caused by the use of fossil fuels. .

Therefore, if it is possible to produce a certain amount of electrical energy using the hydraulic power of naturally occurring movable beams, not only the power to operate the movable beams by producing electrical energy that does not cause environmental pollution, but also the surplus generated electrical energy can be used in irrigation facilities or It will be possible to provide power that can be used for agricultural equipment.

For this purpose, in the prior art, Republic of Korea Patent No. 1132805 'sluice gate opening and closing device equipped with a generator' has been proposed. In this technology, a sluice gate, an opening/closing means for opening and closing the sluice gate, and a power generation means for supplying electricity to the opening/closing means are configured, and the sluice gate is rotatably installed on the drainage channel of a water tank or embankment for storing water or sewage, A power generation means comprising a turbine installed on a water supply path provided on one side and rotated by the energy of water and a generator connected to the turbine to generate electricity is provided, while the sluice gate has a main cylinder member and a failure of the main cylinder member It is provided with an auxiliary cylinder member that operates at the time of operation, and is capable of supplying electricity to the auxiliary cylinder member in case of a failure of the main cylinder member.

Since the turbine is installed on the water supply path provided on one side of the sluice gate, such a sluice gate opening/closing device has a difference in the amount of power generation depending on the amount of water stored. Since water is continuously discharged in this extremely small state, it is difficult to reach a water level above a certain level, and it is not possible to secure an appropriate amount of fresh water, and there is a problem in that the production of electric energy is also low.

Another example of the power generation device is the Republic of Korea Patent No. 1522515, a combined eco-friendly power generation system has been proposed. This device is combined with a door frame to store river water and is configured to be raised and lowered by a hoist. As the low-rise water inlet and discharge passage are formed inside the sluice gate, a discharge control cylinder is formed to control the discharge amount, and the direction in which water is discharged It is possible to generate electricity by configuring a power generating device at the lower end of the first water flow guide port to guide.

This power generation device is complicated as the emission control cylinder is configured inside the sluice gate driven by the switchgear, and the emission control cylinder is always immersed in water, so it is easy to corrode, and maintenance is difficult. In case of heavy rain, the sluice gate is directly subjected to water pressure and there is a risk of damage due to impact by flowing gravel or foreign substances.

In addition, in the existing small hydroelectric power generation in rivers, the water wheel was exposed and facilities including the water wheel were damaged by gravel and various kinds of garbage that were washed away with the water that was blown away during heavy rain.
