Water resources directly and indirectly affect human life. Lakes, rivers, and seas aesthetically not only provide vitality to human life, but also become the foundations of many living things.

In addition, with the development of today's industry, water resources have been used more importantly, and many countries are putting much effort into developing and preserving them.

In the case of Korea where rainfall is limited at a limited time, it is important to properly manage the water resources due to the relatively high damage caused by flooding or drought. The dam-building project, which cleans river water, serves to prevent flood damage and provide river water in case of drought.

In the dam construction as described above, water gates of various types are installed according to purpose, type, and material. In general, a water gate is a door installed to control flow rate by blocking or opening water flow. Sluice is installed in drains provided in banks, rivers, rivers, reservoirs, etc., to prevent the flow of water, and when the amount of water is stored is increased, the drain is opened by a normal switchgear to release the stored water. It serves to emit.

The water gates of dam constructions include conducting water gates that rotate and open the water gates, and open waters that lift the water gates upward.

In the case of conducting hydrologic gates, heavy load doors must be rotated. Especially, there are many difficulties in conducting flood gates that are pushed by high pressure water pressure. do.

In order to solve this problem, the Korean Patent and Trademark Office has proposed and registered a configuration regarding the double doors as patent 10-1370040 (hereinafter referred to as pre-registration).

According to the pre-registered double secretion, it is installed across the waterway, and is installed on the structure in which a flow path through which water flows, is slidably installed in the up and down direction so as to open and close the flow path, and the water drain penetrates through the water. The main sluice, which is installed in the main sluice, is a lifting unit that raises and lowers the main sluice, and the connecting unit can rotate to the main sluice by opening and closing the drain according to the front and rear water level relative to the main sluice. A subslue which is installed to have a cross section larger than the size of the drain and a subsoil that maintains the watertight between the main and sub sluices when the drain is closed; It is formed to have a closed track along the side edges, and the subsluice is easily compressed by the subsluice when the drainage is closed. It is provided with a packing member provided inside the hollow so as to be deformed.

The pre-registration with such a configuration is provided with a sub-sluice which opens and closes the drain of the main gate according to the front and rear water levels in the main gate, which is installed up and down in the waterway. Therefore, there is an advantage that can reduce the manpower required to manage because the operator's opening and closing operation is not required.

The opening and closing adjustment of the auxiliary sluice member 100 is made by the driving force member 300 installed in the tank structure 90 and the auxiliary sluice member 100.

The driving force member 300 is a control piece for receiving the opening and closing driving force of the outlet 93 of the flow pipe 92 on the upper end of the first sluice 110 and the second sluice 120 of the auxiliary sluice member 100. The 111 and the fixing piece 123 are formed to protrude forward, respectively, and the through holes 116 and 126 are formed by puncturing the control piece 111 and the fixing piece 123, so that the tension bolt 130 ) To allow penetration.

The tension bolt 130 has a rod-shaped rod extending from the hexagonal head 133 in the longitudinal direction as in the usual bolt structure, and is provided with a threaded portion 131, and is fastened to the threaded portion 131. Nut 140 for adjusting the length is a configuration that is screwed.

The tension bolt 130 has a threaded portion 131 as the through holes 116 and 126 formed in the control piece 111 of the first sluice 110 and the fixing piece 126 of the second sluice 120. It is installed to be penetrated, but the threaded portion 131 is fixed to the position of the control piece 111 of the first sluice 110 using the nut 140.

At this time, the movement interval 132 of the tension bolt 130 is located at the position of the fixing piece 126 of the second sluice 120, the head 133 of the tension bolt 130 is the second The fixed piece 123 of the water gate 120 is not in contact with the fixed interval position.

As such, the head 133 of the tension bolt 130 at a predetermined interval with respect to the fixing piece 126 is moved to a length of the movement interval 132 together with the sliding of the first sluice 110 and the first The driving force is transmitted to the second floodgate 120 when caught by the stationary piece 126 of the second floodgate 120.
