Abstract

It is related to water gates applied to beams such as rivers and rivers. The buoyancy and hydraulic actuation statements (hereinafter referred to as "water gates"), which are blocking the waterway by their own weight, are automatically received by buoyancy and water pressure as the upstream water level rises. It is a water gate designed to maintain a constant level without artificial operation by opening the waterway to a certain height and opening the waterway, and when the water level in the upstream drops, the buoyancy drops and the waterway is closed again by its own weight.

Sluice (10) is installed in the transverse of the waterway formed so as to control the flow of water is automatically lifted and operated in the waterway by buoyancy and water pressure to open and close the waterway (10). Guide rails 20 provided on the inner wall of the water passages to guide the lifting operation of the water passages of the water gate 10, and guide rollers provided on both sides of the water gate 10 against the guide rails 20 30) and the buoyancy chamber 40 is provided in the interior of the water gate to adjust the buoyancy.

Description

BUOYANCY AND WATER PRESSURE TYPE MOVABLE DAM (GATE)}

In rivers and rivers, water beams are installed to store or use water. In the past, the floodgates installed here have a structure that maintains a certain level by overflowing water in the upper layer. Accidents such as floods or disasters caused by heavy rains were severe due to the acceleration of environmental pollution by preventing the movement of fish and the limitation of measures by manpower. In order to compensate for this, a sluice gate called "auto beam" has been developed, but due to the use of hydraulic equipment or mechanical operation, the possibility of water pollution due to the leakage of hydraulic oil and the excessive cost of production due to auxiliary equipment are considered to be impractical.

Therefore, the present invention has been devised to solve the above-mentioned problems, and by using natural phenomena, it minimizes ancillary facilities, improves economic efficiency, and eliminates mechanical and mechanical factors by avoiding the causes of breakdowns and environmental pollution. It is to provide buoyancy and hydraulic operation to minimize the damage even during natural disasters.

10: hydrological 20: first buoyancy chamber 30: guide roller 40: buoyancy chamber

The buoyancy and hydraulic operation language of the present invention is installed transversely on the inside of the waterway so as to automatically lift and operate from the waterway by buoyancy and water pressure to open and close the waterway (10). Guide rails 20 provided on the inner wall of the water passages to guide the lifting operation of the water passages of the water gate 10, and guide rollers provided on both sides of the water gate 10 against the guide rails 20 30) and a buoyancy chamber 40 which is provided inside the water gate to adjust the buoyancy. A characteristic technique of the present invention for achieving the above object is to adjust the weight of the water gate using buoyancy and water pressure. The opening and closing method of opening and closing the gate is a basic feature.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a normally closed hydrological gate to which the present invention is applied, and FIG. 2 is a state in which the water level is controlled while the hydrological gate is opened and closed by buoyancy, and FIG. 3 is an open gate of the simulated hydrological gate.

Reference numeral 10 is a sluice gate that automatically opens and closes the hydraulic opening by buoyancy and water pressure, and the reference numeral 20 is a guide roller for smoothly operating the up and down water gates. The guide rail is a guide rail that prevents escape and guides the floodgate in the direction of water flow. Reference numeral 40 is a buoyancy chamber that can adjust the buoyancy by injecting or removing compressed air into the buoyancy chamber provided inside the floodgate.

Referring to the hydrological opening and closing method according to the present invention made of such a configuration as follows.

The water gate 10 which was blocking the waterway due to its own weight has guide rollers 30 provided on both sides of the water gate which are cloud-supported by the guide rail 20 provided on the inner wall of the water passage as the upstream water level rises. ) By the rising and falling smoothly. When the water level is opened up to a certain height automatically and the upstream water level decreases, the buoyancy and water pressure drop, and the water drainage is closed again by the weight of the buoyancy. The guide rollers 30 provided on both sides of the buoyancy and the sluice 10 are guided by the guide rails 20 so that the sluice 10 is horizontally positioned in the same direction as the direction of the flow of water to prevent damage of the sluice caused by foreign substances. In addition, a method of injecting or removing compressed air into the buoyancy chamber 40 provided in the interior of the water gate 10 or attaching an air cylinder as necessary to adjust the opening and closing degree of the water gate.

As can be seen from the above, the present design is a distinctive design that does not require a conventional lifting device or hydraulic device, because it has a basic feature of opening and closing in consideration of the weight, buoyancy, and flow rate of the gate. It is increased and the failure rate is minimized, and it is possible to prevent the environmental pollution caused by the accumulation of sediment or oil spills and to minimize the damage in case of flood or disaster even without special manager. If the present invention is applied to the present invention, it is possible to use enough water at a low cost as well as to prevent environmental pollution while minimizing damage in case of flood or disaster.
