Abstract

It is a kind of sluice applied to beams for rivers and rivers, and it is a movable word that applies the principle of buoyancy body and lever (called automatic sluice = hereinafter 'sluice).

Description

Application of buoyancy bodies and levers {APPLY A BUOYANCY BODY AND LEVERAGE OF MOVABLE DAM (GATE)}

The past form of hydrology applied to the reservoir for rivers and rivers is a structure that maintains a certain level by overflowing water in the upper part, so that sediment accumulates in the lower part or prevents the movement of fish to accelerate environmental pollution. Due to the limitations of measures by human resources, the floods and disasters caused by heavy rains were severe.

In order to compensate for this, a water gate called automatic beam has been developed, but due to the use of hydraulic equipment or mechanical operation, it is considered that practicality is low due to excessive concern about water pollution and excessive manufacturing cost due to auxiliary equipment.

Therefore, the present invention has been devised to solve the above-mentioned problems. As a result, it minimizes incidental facilities to increase economic efficiency and eliminates mechanical methods, thereby eliminating factors of breakdown and environmental pollution, and also during natural disasters such as flooding. Seek to minimize damage.

10: buoyant body, 20: sprocket, 30: rack bar, 40: guide roller, 50: guide rail

Referring to the characteristic technology of the present invention to achieve the above object is as follows.

The water gate that blocked the waterway by its own weight has a buoyancy body 10 which is buoyant as the water level rises upstream, a sprocket 20 provided in the buoyancy body 10, and a rack bar against the sprocket 20 ( It is a water gate designed to maintain constant water level without artificial operation by automatically opening the waterway to a certain height by opening the waterway and then opening the waterway to the upstream water level and then lowering the buoyancy and closing the waterway again by its own weight. B. At high water level, the water gate becomes the same as the direction of water flow due to its own buoyancy, guide rollers and guide rails. The structure of the water gate is streamlined to reduce the damage caused by the flow velocity to a minimum.

By creating a buoyancy chamber inside to obtain its own buoyancy on the weight of the floodgate, the floodgate can be completely opened without artificial manipulation during flooding or high water level, and the opening and closing degree can be added or decreased by adjusting the rack bar up and down to maintain a constant water level. One way is to have the basic characteristics.

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

Figure 1 shows the structure as a front view of the water gate to which the present invention is applied, Figure 2 is a cross-sectional view of the normal state of the water gate to which the present invention is applied, Figure 3 is a state in which the water level is adjusted while the water gate is opened and closed by buoyancy, Figure 4 shows the flood gates are completely open during floods or high water levels.

Reference numeral 10 is a buoyancy body filled with buoyancy material acting on the water level change, reference number 20 is a sprocket for transmitting the rotational force to the rack bar by the action of the buoyancy body, reference number 30 is operated up and down by the sprocket to open and close the water gate It is a working rack bar.

Reference numeral 40 is a guide roller for smoothly operating the upper and lower functions of the hydrologic gate, and reference numeral 50 is a guide rail for preventing the departure of the guide roller and positioning 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 due to its own weight has a buoyancy body 10 that is buoyant as the water level rises upstream, a sprocket 20 provided on the buoyancy body 10 and rotates against the sprocket 20. The rack bar 30 moves automatically to a certain height to open the waterway, and when the upstream water level decreases, the buoyancy drops and closes the waterway again by its own weight so that the water level can be maintained at all times without artificial operation. It is a sluice, it is a way to allow the opening and closing degree according to the up and down adjustment of the rack bar 30.

When the flood or full water level, the water gate becomes the same as the direction of the water flow by its buoyancy and the guide roller 40 and the guide rail 50, and the structure of the main body is wired to reduce the damage to a minimum.

As seen from the above, the present invention applies the principle of buoyancy body and lever, and since it is basically characterized by the opening and closing method by the guide rail considering the water pressure and flow rate, the design is clearly distinguished without the need for the existing lifting device or the hydraulic device. As the device is simplified, durability is increased and failure rate is minimized, and it is possible to prevent environmental pollution due to accumulation of sediment or oil spills, and to minimize damage during flooding or disasters without a special manager. As a structure, if the present invention is applied to a water reservoir for rivers or rivers, 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. You will see.
