Description

Floating Dam Structures.

The present invention relates to a buoyant movable beam structure, and more specifically, in the case of a flat level, the buoyancy of the beam body is raised by buoyancy so that the beam portion protrudes from the lower surface, thereby blocking the flow of the flow of water, However, in the case of flood level, water is introduced into the main body of the beam so that the main body sinks so that the beam portion does not protrude from the bottom of the river bed, thereby allowing the flow of water to flow smoothly downstream. Beam structure.

Korean Patent Laid-Open Publication No. 10-2005-100341 discloses a conventional art in which a bow is moved by buoyancy to block water flow or open water flow. However, when the movable beam is moved by rotation as described above, a considerably wide area is required to secure the rotation range of the beam, and when the beam is raised, There is a limit to the difficulty. In other words, when a large amount of water flow is pushed up, the movable type of the rotating type like the conventional one can not support the force by the water flow, so that it is easily broken, and accordingly, the function of the beam can not be faithfully exhibited.

Korean Patent Laid-Open Publication No. 10-2005-100341 (published Oct. 18, 2005).

It is an object of the present invention to provide a movable beam structure that can overcome the limitations of the movable beam according to the prior art in the above-described manner and actively cope with the water level while sufficiently supporting the force by the water flow .

Particularly, according to the present invention, since the buoyant force is applied to the buoyancy, there is no need to supply an artificial energy for the operation of the beam. In the case of the float level, the bowler blocks the water flow and faithfully performs the function of storing water. So that the flow of water can smoothly flow downstream.

In order to accomplish the above object, according to the present invention, in a float level state, a bowler obstructs water flow and faithfully performs a function of storing water, and in a flood level state, the bow descends to smoothly flow the water flow, A movable beam structure is provided.

Specifically, in the present invention, a landfill is embedded in a lower part of the bed and flows upstream and downstream of the water, and a movable beam installed in the landfill and buoyed by buoyancy; The movable view comprises a vertical body in the form of a vertical wall and a lower body integrally formed under the vertical body and positioned in the landfill; There is an internal space in the movable beam; A front openable front opening is formed in the upstream side of the vertical body so as to allow the upstream water to flow therein; And an openable and closable drain port for draining the water filled in the inner space of the movable beam is formed on the downstream side surface of the lower body; In the flat water level, due to buoyancy of the water flowing through the landfill, the moving beam rises and the vertical body blocks the flow of water to be blocked; Wherein the buoyant movable beam structure is configured such that water is filled in the inner space of the movable beam through the front opening of the flood water, and the movable beam is lowered to flow the water beyond the vertical body to the downstream.

The movable beam structure of the present invention may have a structure in which a cut-and-open portion is formed on an upper surface of the buried container and a movable body moves up and down through the cut and open portion. Further, And a shock absorbing plate for absorbing the impact by contact when the movable beam is lifted may be provided between the lower surface of the upper plate and the lower surface of the buried container.

According to the movable beam structure of the present invention, the water flow smoothly flows because the beam is not protruded at the level of the flood level while faithfully performing the function of blocking the water flow by blocking the water flow at the flat water level state.

Particularly, the operation cost can be reduced because buoyancy through the inflow and outflow of the water flow is performed without the artificial energy supply.

However, in the movable beam structure of the present invention, since the beam is vertically inclined, the area required for the operation of the beam is limited by the prior art So that it is possible to easily secure the site for installation, and the cost can be greatly reduced.

Furthermore, since the movable beam structure of the present invention has a structure in which the beam vertically ascends and descends as described above, even if a large amount of water flows, it is possible to actively cope with the water level of the water stream while sufficiently supporting the force of the water stream .

As shown in the drawing, the movable beam structure according to the present invention includes a buried box 20 buried in a bed and a movable beam 10 installed in the buried box 20 and lifted and lowered by buoyancy .

The embedding box 20 is installed to be embedded in the bed 30 as a member that receives water upstream from the bed and flows the inflow water through the downstream. An inlet 21 through which the water flows from the upstream is formed in the upstream of the embedding box 20, and the inlet may be provided with a latching screen for filtering out foreign substances as required. On the upper surface of the embedding box 20 is formed a cut-out opening 22 which is long along the width of the stream. The cut-out opening 22 is provided with a vertical body 16 of the movable beam 10 And the vertical body 16 is raised or lowered to protrude from the upper surface of the embedding box 20 or be embedded in the embedding box 20 without protruding from the upper surface of the embedding box 20.

3 to 5, the movable beam 10 includes a vertical body 16 formed in the form of a vertical wall, and a movable member 20 integrally formed under the vertical body 16, The vertical body 16 and the lower body 17 have an empty space therein, and these empty spaces are in communication with each other. That is, the inner hollow space of the vertical body 16 and the inner hollow space of the lower body 17 are in communication with each other, and therefore, the movable hollow 10 has the inner space 14 therein. 3, a front opening 11 through which water flows upstream can be formed on the upstream side surface of the vertical body 16, and the front opening 11 is provided with a valve And the front openings 11 can be opened or completely blocked as necessary. The front openings 11 may be elongated in the width direction of the vertical body 16 as illustrated in the drawing, but may be formed in a manner that a plurality of holes are intermittently arranged. In the embodiment shown in the drawing, the vertical body 16 is shown in a tapered shape with its thickness decreasing toward the upper part. However, the front body and the rear face of the vertical body 16 are formed as vertical faces, 16 may be constant up and down.

4, on the downstream side surface of the lower body 17 in the movable beam 10, water is filled in the inner space 14 of the movable beam 10, as will be described later, And a drain port 13 for drainage is formed. A valve (not shown) is also provided in the drain port 13 so that the drain port 13 can be opened or shut off as required. Air is supplied to the internal space 14 of the movable beam 10 or air is discharged from the internal space 14 of the movable beam 10 to the vertical body 16 of the movable beam 10, (12) are formed. The drain hole 13 may also be formed long in the width direction of the lower body 17 as illustrated in the figure, but may be formed in a shape in which a plurality of holes are intermittently arranged.

As shown in the figure, the movable beam 10 has a vertical body 16 protruding from the upper surface of the embedding box 20 through the cut-out opening 22 of the embedding box 20, As a "beam" While the lower body 17 is located in the landfill 20. An impact is generated between the lower surface of the upper plate of the embedding chamber 20 and the lower body 17 when the movable beam 10 is lifted up from the upper plate of the embedding box 20 in which the cut- A shock absorbing plate 24 made of an elastic material such as rubber, synthetic resin, or the like is provided so as to absorb shock.

The operation of the movable beam structure according to the present invention will now be described with reference to FIGS. 6 to 9. First, in the state of a flat water level, water upstream is introduced through the inlet 21 of the landfill 20, And then flows downstream. The arrow K in FIG. 6 indicates that the upstream water flows through the interior of the landfill (20) and flows downstream. Reference numeral 23 denotes a water flow passage 23 through which water flows in the interior of the landfill 20.

Since the interior of the movable beam 10 is empty, the buoyancy generated in the process of passing the water in the upper stream through the interior of the buried chamber 20 acts upward with respect to the movable beam 10, 10 protrude above the upper surface of the embedding chamber 20 through the cut-out opening 22 to confine the upstream water. At this time, a part of the water flowing from the upstream can flow down the vertical body 16 to flow downstream. On the other hand, the water on the upstream side flows into the interior of the embedding chamber 20 through the inlet 21 of the embedding chamber 20 and is buried. (20) and always flows downstream.

When the water level rises to reach the flood level, as shown in FIG. 7, the valve provided in the front opening 11 of the movable beam 10 is opened to open the front opening 11. Accordingly, the water upstream of the front opening 11 flows into the empty space 14 of the movable beam 10 and is filled therein. At this time, when the air hole 12 is opened, the air existing in the internal space 14 of the movable beam 10 is discharged through the air hole 12, so that water easily flows into the internal space 14 of the movable beam 10 (14).

As the inner space 14 of the movable beam 10 is filled with water, the weight of the movable beam 10 is increased, and the movable beam 10 sinks in the landfill 20. When the movable beam 10 is submerged, the vertical body 16 protruding from the upper surface of the embedding box 20 is also lowered, so that the flow is blocked by the vertical body 16, Flows vertically through the vertical body 16 and flows downstream.

When the inner space 14 of the movable beam 10 is filled with water and the movable beam 10 is further submerged, the vertical body 16 is completely lowered as shown in FIG. 8 and enters the inside of the embedding box 20 And the water flows downward easily without any hindrance, and the water level is lowered. At this time, the movable beam 10 may sink to block the water flow passage 23 formed inside the burial chamber 20.

The water contained in the movable beam 10 is drained by opening the drain hole 13 formed in the movable beam 10 after stopping the inflow of water through the front open mouth 11. At this time, if air is injected through the air holes 12, air can be introduced and water can be drained more smoothly through the drain hole 13. When the water filled in the movable beam 10 is drained as described above, the movable beam 10 becomes lighter so that the movable beam 10 floats again as shown in FIG. 9 by the action of buoyancy. When the movable beam 10 is lifted, the vertical body 16 passes through the cut-open portion 22 and protrudes above the upper surface of the embedding chamber 20 to be restored to the state of FIG. 6, .

As described above, according to the movable beam structure of the present invention, the movable beam 10 rises by the buoyancy when the float level is raised, and the beam portion protrudes from the upper surface of the buried chamber 20 to block the upstream water. The water in the inner space of the movable beam 10 is lifted to increase the weight of the movable beam 10 so that the vertical body 16 enters into the buried chamber 20 so as not to protrude, The water of the water can flow smoothly without being confined. On the other hand, when the water level is lowered, the water filled in the inner space of the movable beam 10 is discharged again to lighten the weight of the movable beam 10, so that the movable beam 10 rises by buoyancy, (16) protrudes above the upper surface of the landfill (20) and confines the water.

As described above, according to the present invention, since the movable beam 10 vertically ascends and descends, the movable beam 10 is operated by rotation, so compared with the conventional art in which a considerably wide area is required for securing the rotation range of the beam, It is possible to secure the site for the installation and to reduce the cost accordingly.

Particularly, in the present invention, since the movable beam 10 is vertically moved up and down by the buoyancy force, the movable beam 10 can smoothly operate without artificial energy supply, thereby reducing the operation cost of the movable beam. do.

The movable beam structure of the present invention has a structure in which the movable beam 10 vertically moves up and down and the lower body 17 is integrated with the lower body 17 in a state of being embedded in the storage case 20 And the vertical body 16, which is vertically present, supports the force from the water flow, so that even if a large amount of water flows, it is possible to have a sufficient resistance.

Furthermore, according to the present invention, the buoyancy due to the water flow eventually becomes the ascending / descending power of the movable beam 10, so that the ascending and descending degree of the movable beam 10 is determined according to the water level of the water stream, The effect is realized.
