Description

{NON-POWERED FLOODGATE}

The present invention relates to a non-powered water gate device, and more specifically, to a non-powered water gate device installed on a coast, river, dam, etc., which can block water that suddenly increases during the rainy season (monsoon season) due to global warming, without power.

In general, a sluice gate is installed at the end of a waterway such as a river or stream, transversely to the waterway, to facilitate the drainage of inland water to the outer water side, to block the backflow of outer water to the inner water side, to utilize water resources by storing inland water, and to have some of the three functions of forced drainage of inland water when the outer water level is high.

In particular, water gates are installed on waterways such as rivers, embankments, and breakwaters, and are normally open to allow the upstream inland water to drain naturally into the downstream offshore waters. However, when the amount of rainfall increases due to heavy rain, monsoon rain, or typhoons, and the offshore water level rises above a certain level, the water gates are lowered to close the waterway, thereby blocking offshore water from flowing into the onshore waters.

This technology related to water has been proposed in Korean Patent No. 0497044.

However, Patent Document 1 had a problem in that the structure increased because the sluice gate was opened and closed by driving it with driving force, and periodic maintenance was required.

Referring to FIGS. 1 to 7, the non-powered water gate device (100) of the present invention includes a body (110), a door (120), a float (130), and a closing force providing unit (140).

The body (110) is formed with openings at the front and rear as shown in FIGS. 1 to 3 and FIGS. 5 to 7, and a flange is formed on the opened front edge, and a panel part (112) is joined to the inside.

The panel portion (112) is provided with side panels (1120) parallel to each other on both sides so as to be positioned on the opposite inner wall surfaces of the body (110), and both ends of the front panel (1122) are connected to the front of the adjacent side panel (1120) so as to have a “ㄷ” shape when viewed from above.

At this time, the panel part (112) is provided with a square hole (1124) formed in the front panel (1122) so that it can be opened and closed by the door (120), and the sealing with the door (120) is maintained by a leak-proof rubber packing (P1).

And, the panel section (112) is formed with a receiving section (1126) which is a roller box to protect against waves of incoming water while a closing force providing section (140) is positioned at each rear end of the side panel (1120).

Furthermore, the panel part (112) has a leak-proof rubber packing (P2) formed in a square frame shape on the lower surface of the front panel (1122) and the lower slope of the side panel (1120), so that airtightness is maintained when the floating body (130) is in close contact.

In this way, interference or accumulation of foreign substances or floating objects pushed by water resistance or waves can be avoided by the leaky rubber packing (P1, P2).

And, in order to avoid interference or accumulation of foreign substances or floating objects pushed by water resistance or waves in the space between the side panel (1120) and the floating body (130), rubber (P3) is installed.

In addition, the leak-proof rubber packing (P2) is equipped with a double guide (not shown in the drawing) on the upper side to cover the leak-proof rubber packing, thereby preventing the inflow of foreign substances from the source.

The door (120) is rotatably provided on the inner ceiling surface of the body (110) as shown in FIGS. 1, 2, 5 and 7 to quickly block overflowing water as the length of the lower floating body (130) is reduced.

At this time, the door (120) is exemplified as being rotatably provided on the inner ceiling surface of the body (110) by a hinge (122) to open and close the hole (1124) of the panel portion (112).

In this way, when the door (120) is equipped as an operational type, it is opened by an internal water pressure higher than the external water level.

In contrast, the door (120) can also be provided as a fixed type. That is, when the door (120) is provided as a fixed type as shown in Fig. 6, it is preferable that it be formed at the same angle as the tip of the closed float (130). This means that when the outside water level rises higher than the inside water level, the float (130) is closed by the rise in the outside water level, and the upper end of the float (130) is pressed against the lower end of the door (120), thereby closing the water gate.

The float (130) is provided rotatably by a hinge (131) on the inner bottom surface of the body (110) while the interior is empty as shown in FIGS. 1, 2, 5 to 7, but is normally open when lifted by buoyancy or pressure due to water, closed when the outside water level is higher than the inside water level, and open when the inside water level is higher than the outside water level.

At this time, the floating body (130) has a gate guide (132) with a fan-shaped side shape positioned upright on both sides of the upper surface, and a connecting port (134) with a square hole formed on the rear of the gate guide (132) is connected, and wires (142) of a closing force providing unit (140) are connected to each end of the connecting port (134).

Furthermore, the floating body (130) is provided with packing identical to the leak-proof rubber packing (P2) provided on the panel portion (112) at the edge, so that airtightness can be maintained by the double structure.

In addition, the float (130) has a step (1320) at the head to maximize the inflow of water, and the inlet (1340) flowing into the lower part of the step (1320) is shaped like an arc to minimize water resistance and enable quick opening and closing.

The closing force providing unit (140) is positioned within the receiving unit (1126) of the panel unit (112) and is connected to the upper end of the connecting port (134) of the floating body (130) in a spaced state to provide closing force when the floating body (130) is closed.

At this time, the closing force providing unit (140) is connected to a wire (142) in a spaced state at the top of the connecting port (134) of the floating body (130), and a weight (144) is provided at the end of the wire (142).

The wire (142) is guided in the direction of movement by a plurality of rollers (R).

In this way, the door opening and closing process of the non-powered water gate device (100) according to the present invention is explained as follows.

First, in the normal case where the external and internal water levels are the same, the door (120) is closed and the float (130) is opened, and at this time, the weight (144) is maintained in a rising state by the opening of the float (130) (see FIG. 1).

Next, when water suddenly rises and the water gate rises due to the outside water level, water flows in through the step (1320) of the float (130), and the water resistance is minimized by the arc-shaped inlet (1340) formed at the bottom of the step (1320), so that the float (130) rotates quickly. Then, when the upper rotation of the float (130) occurs, the weight (144) is lowered by the weight, so that the float (130) quickly rises, thereby closing the float (130) (see FIGS. 5 and 6).

Next, when the internal water level is higher than the external water level, the door (120) and the float (130) are opened by the internal water, and the weight (144) is maintained in a rising state by the opening of the float (130) (see FIG. 7).

The configurations included in the various embodiments described above may also be implemented as embodiments of various other possible combinations of modifications not exemplified above, as long as they are not combinations that are clearly mutually exclusive in terms of implementation.
