Description

Actively controlled floating waterway for tidal current generation using an air compression booth {omitted}

The present invention relates to an actively controlled floating waterway for tidal current power generation using an air compression booth, and an air compression booth for hydroelectric power generation devised by the inventor of the present invention and applied for a domestic patent (Application No. 10-2021-0027312) and a pressure control tank was conceived by combining

More specifically, it actively blocks the lower space that rises and lowers to allow the discharge water of the embankment sluice to flow in, seals the opening where the aberration is installed, and passes it through the air compression method while maintaining the discharge pressure and discharge flow rate of the sluice gate to continuously multi-stage in one waterway. It relates to an actively controlled floating waterway that enables power generation and smooth seawater distribution.

In general, seawalls are used for the purpose of trapping and discharging water, and a huge amount of water resources is being discarded through sluice gates.

In addition, even in a single-current power generation method that generates power with rising water, such as the Sihwa Lake tidal power plant, the ebb tide is simply dumped into the sea.

The reason why such a huge energy source is being abandoned is that tidal power plants cannot be built as many problems such as depletion of fish stocks, loss of tidal flats, and destruction of the marine ecosystem are raised due to the excessive cost of constructing huge underwater structures and limited seawater circulation. .

On the other hand, mooring and bottom-type tidal current generation methods using fast flow rates discharged from seawalls have been proposed. However, when water turbines are installed on open water surfaces or underwater without water pressure pipes, pressure loss occurs due to the property of water to return when clogged, and power generation efficiency is significantly reduced, while underwater construction costs are not commercialized due to uneconomicalities.

In addition, the tidal current power generation method, which is currently widely used, improves power generation efficiency with a structure that minimizes pressure loss by making the cross-sectional areas of the hydraulic pipe and the propeller the same. However, this power generation method has an uneconomical disadvantage that only one aberration can be installed in one hydraulic pipe.

Accordingly, in order to produce a large amount of electricity from one dam, since several hydraulic pipes are formed to generate power, the limited quantity of the dam is inevitably depleted quickly, and as the water level rapidly decreases, the amount of power generation gradually decreases. This is an uneconomical method.

In addition, when a water wheel in the form of a spinning wheel is installed in a waterway with an open top, it is not possible to install multiple water wheels because water rises to the low-density atmospheric layer (air) and steps are generated between the front and rear water surfaces of the water wheel in the form of steps. In addition, the power generation efficiency is also reduced due to pressure loss.

As discussed above, tidal power generation cannot be economically feasible because pressure loss occurs on the open surface or underwater, and tidal power generation cannot be constructed anymore because of the destruction of the marine ecosystem and excessive construction costs. Or, there are still problems and disadvantages that only one aberration can be installed in the hydraulic pipe.

The present invention was developed in view of the problems of the prior art, and an object of the present invention is to actively block the lower space that is raised and lowered by installing a floating type in the dike sluice forming a constant flow rate, and to maintain the discharge pressure and discharge flow rate of the sluice gate. It is to provide an active control type floating waterway for tidal current power generation using an air compression booth that enables continuous multi-stage power generation by passing through an opening where an aberration wheel is installed in an air compression method as much as possible, and at the same time ensures smooth seawater circulation.

As a means for achieving the above object, the present invention is an active control type floating type that continuously realizes multi-stage power generation and facilitates seawater circulation by maintaining the discharge pressure and discharge flow rate of the sluice by an air compression method by introducing the discharge water of the embankment sluice gate. As a waterway, more specifically, an opening for installing an aberration is formed in a pressure waterway open on both sides, a power generation room composed of a multi-layered buoyancy structure is formed on the upper part of the pressure waterway, and a pile fixing part is formed on both sides of the power generation room. The enclosure body, a cylinder formed at the pile fixing part of the enclosure, a pile mounted on the cylinder and fixed to the sea floor, and one side formed in a foldable manner to actively block the lower space of the enclosure for elevating the pile A foldable blocking part hinged to the lower part and the other end hinged to the sea floor fixing part, an aberration installed in the opening with the pressure water of the hull, and sealing the aberration and the opening and monitoring the water level to prevent water from rising It includes an air compression booth equipped with a water level sensor, an air supply unit, and an air compression control unit for supplying air.

According to one embodiment of the present invention, a water intake unit for receiving water discharged from the water gate and discharging it to be supplied to the waterway of the enclosure is further included.

According to one embodiment of the present invention, the enclosure is arranged in a plurality long in succession, and includes a rear end sluice gate formed at an end of the last enclosure to enable bi-directional power generation.

According to one embodiment of the present invention, a plurality of aberrations are installed in the pressure channel, and a water flow guide portion formed in a convex shape to guide water flow vertically is included at the bottom.

According to one embodiment of the present invention, the breakwater is characterized in that the enclosure is formed with a plurality of lengths, and a second breakwater may be formed at the end of the enclosure formed long.

According to one embodiment of the present invention, a side blocking portion formed so that rubber diaphragms cross each other is formed on a wall of the water intake portion facing the enclosure, and a brush blocking portion opposing the wall is formed on the side of the foldable blocking portion, so that the enclosure is It is characterized in that water from the intake part is prevented from flowing out when the water intake part is moved up and down.

According to one embodiment of the present invention, a plurality of pressure water tanks formed in the plurality of pressure water channels to offset water hammer action and negative pressure are included.

In addition, since it can be manufactured and installed on land as a floating type, the construction period is short and the construction cost and maintenance cost are low.

In addition, it is possible to block the lower part from going up and down, so that the amount of power generation and the time of power generation can be accurately predicted as well as the increase in power generation.

In addition, since it is formed in the form of a waterway, not only does seawater flow smoothly, but it is an eco-friendly structure in which large fish and small fish can naturally exchange.

In addition, unlike tidal power generation formed in bays, it can be installed in straits through which tidal currents pass, so the range of limited terrain is wider.

In addition, it is possible to permanently produce electricity in large quantities using infinite tidal energy, and to use abundant electricity to produce hydrogen, which is future energy, in an eco-friendly way, thereby replacing fossil fuels and rapidly responding to climate change.
