Abstract

PURPOSE: A buoyant movable weir is provided to heighten economical efficiency by minimizing incidental facilities, to prevent environmental pollution, and to minimize damage caused by natural disasters such as a flood. CONSTITUTION: The buoyant movable weir comprises an air inlet(10) injecting or cutting off compressed air into a buoyancy room of a water gate, a primary buoyancy room(20) occurring basic buoyancy by filling up buoyant materials or injecting air, a secondary buoyancy room(30) controlling buoyancy at any time by injecting air, a conveyance way(40) making water flow in and out in inverse proportion to the amount of air in the buoyancy room to control the buoyancy of the secondary buoyancy room(30), a guide roller(50) operating a water gate vertically, and a guider rail(60) preventing the separation of the guide roller(50) and fixing the water gate in the direction of a water current.

Description

Buoyant Movable Statement (Sluice) {BUOYANCY TYPE MOVABLE DAM (GATE)}

In rivers and rivers, there will be installed beams for storing or using water. In the past, the water gate installed here has 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 hydrological gate called "operating language" has been developed, but due to the use of hydraulic equipment or mechanical operation, the possibility of water pollution caused by the leakage of hydraulic oil and the excessive cost of production due to auxiliary equipment, etc. are considered to be impractical.

Therefore, the present invention has been devised to solve the above-mentioned conventional problems, by minimizing auxiliary facilities using natural phenomena to increase the economics and avoiding the mechanical method, eliminating the causes of failure or environmental pollution, and also flooding, etc. To minimize damage even during natural disasters.

Referring to the technical features of the present invention to achieve the above object is as follows.

The water gate, which was blocking the waterway due to its own weight, is buoyant as it rises upstream and automatically opens up to a certain height, and when the water level is lowered up, the waterway decreases the buoyancy and closes the waterway again by its own weight. It can maintain constant water level without flood, and in the event of flood or high water level, the water gate is the same as the direction of water flow due to the role of its own buoyancy and guide roller, and it is structured to minimize damage by streamlining the structure of the main body. The main feature is to create a buoyancy chamber and add or remove compressed air to it, or attach an air cylinder to control the opening and closing of the gate.

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 adjusted while the hydrological gate is opened and closed by buoyancy, and FIG. 3 is an open gate of the simulated flood gate.

Reference numeral 10 is an air inlet for injecting or blocking compressed air into the hydro buoyancy chamber, reference numeral 20 is a first buoyancy chamber for generating basic buoyancy by filling a buoyancy material or injecting air, Reference numeral 30 is a second buoyancy chamber to adjust the buoyancy at any time by the method of injecting air (air cylinder can be applied if necessary), reference numeral 40 is a buoyancy to adjust the buoyancy of the second buoyancy chamber It is a water outlet where water flows in inversely proportional to the actual air volume.

Reference numeral 50 is a guide roller for smoothing the up and down action of the water gate, and reference numeral 60 is a guide rail to prevent the departure of the guide roller and to position the hydrological gate in the direction of water flow.

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

The water gate that blocked the waterway by its own weight (Fig. 1) is buoyant as it rises upstream and automatically opens to a certain height, opening the waterway (Fig. 2). By closing the waterway again, the water level can be continuously maintained without artificial operation.In the case of flood or high water level, the water gate is the same as the direction of water flow by the role of its own buoyancy (20) and guide rollers. It is a structure that can be reduced to a minimum (Fig. 3), and the buoyancy chamber (30) therein can be added to the method of injecting or removing the compressed air therein, or by attaching an air cylinder as needed to adjust the opening and closing of the water gate That's one way.

A detailed description of the second buoyancy chamber is as follows.

When the compressed air is supplied to the buoyancy chamber 30, the water that has been filled in the buoyancy chamber 30 is discharged to the water passage 40 by the compressed air. The buoyancy chamber 30 is filled with air, and as a result, the buoyancy acting on the sluice gradually increases, and the water gate rises in proportion to it. On the contrary, when the air filled in the buoyancy chamber 30 is gradually discharged, the water passes through The water polo 40 is appended to the buoyancy is gradually reduced, while being lowered by the weight of the water gate is a structure that can adjust the degree of opening and closing.

As described above, the present invention is a distinctive invention that does not require a conventional lifting device or hydraulic device, because the present invention is characterized by the opening and closing method in consideration of the weight, buoyancy, and flow rate of the hydrologic 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 not only can use the usual sufficient water at a low cost, but also to minimize the damage during floods or disasters, it will be able to see the effect of preventing environmental pollution in advance.
