Description

Storage device for discharge of pneumatic beams {APPARATUS FOR DEFLATION UNDERFLOW WATER OF AIR PRESSUR TYPE MOVABLE}

The present invention relates to a pneumatic movable beam which is installed in a river or a river, and adjusts the water level by changing the height of the steel panel by the ups and downs of the air bag according to the air injection. When the target water level is changed by the water flowing in the upstream and flows to the upper part of the steel panel, the water flowing in the lower flow is discharged preferentially than the overflowed amount to prevent the decay of the water accumulated in the lower part while maintaining the target water level. The present invention relates to a storage water discharge device of a pneumatic movable beam to make the vibration prevention of the steel panel generated by the overflow current.

In general, many rubber dams, such as folding or ups and downs, have been developed as banks of agricultural / industrial intakes, water intakes, and freshwater inflows. It is attracting great attention as a bank for embankment because it is easy to secure the effective water quantity and install it easily, and it controls the height of the rubber dam by the air pressure according to the desired water level.

Most of these rubber dams are filled with air for inflation and ups and downs of the rubber tube, and the fixing device for fixing the airbag to the concrete and the levee and the pipe for supplying or discharging the air. Equipment, blowers, and float valves for level control.

However, the above-mentioned rubber dams are made of rubber tubes to install a weir, so that they are covered at the flood level and are horizontal to the riverbed concrete in the river, so that they do not interfere with the cross-sectional area of the water. There is a problem in applying the fresh water function of the river flexibly, and also because the rubber tube is directly exposed to the oil from the upstream, sharp rocks or driftwood rolling into the riverbed by falling rocks or strong water pressure in mountainous areas, etc. When the shock from the emulsion of the rubber tube is torn or there is a problem that can not function as a hole or bank embankment.

To this end, in recent years, using a rubber tube and a high-strength concrete panel as described above to form a beam and then pneumatically, the water level of the river is easily controlled by laying down and raising the concrete panel by ups and downs or rubber bands, In addition, a lot of pneumatic movable beams are installed to prevent the damage of the rubber tube due to the emulsion coming from the upstream by blocking the concrete panel in advance.

As an example of such a pneumatic movable beam, it is known by Korean Patent Registration No. 367227 (name: pneumatic movable beam).

According to the pneumatic-type movable beam according to the patent registration No. 367227, the base plate which is placed on the river floor as a concrete structure; A plurality of pedestals fixedly installed at predetermined intervals on the base plate and having shaft supports; A predetermined position is rotatably coupled by the shaft support and the rotating shaft installed on the pedestal, and a reinforcing panel is formed on the rear surface for strength reinforcement, and formed at both ends of the reinforcing panel to be coupled to the shaft support by the rotating shaft. It has a fastening jaw formed in the fastening hole, the first sealing member is installed at the lower end to seal between the base plate, the second sealing member for sealing both sides is installed on both sides, the vortex spoiler to block the pulsation of water is the top A panel unit including a plurality of panels installed in the panel; It is formed to have a cylindrical shape extending in the longitudinal direction, and is fixedly installed on the back of each panel, which is 1/5 to 3/5 of the water depth to open and close the panel even with a small expansion force, and is contracted and expanded by an air compression means. A plurality of airbags for rotating the respective panels; A rounding part having a front portion rounded to guide the floating part to the panel side in front of the panel portion; It provides a pneumatic movable beam including a protective column having a stopper extending from the rounding portion to limit the range of rotation of the panel.

When the pneumatic actuating beam according to the patent registration No. 367227 pushes the reinforcement panel by inflating the airbag by the injection of air, the entire high-strength concrete panel part rotates in the opposite direction of the flow direction of water about the rotational axis to almost the ground. By being in a vertical state, water is stored at a desired level, and on the contrary, when the airbag of the airbag is discharged and coated, the panel portion supported by the airbag is rotated in the direction of water flow around the rotational axis to be in a horizontal state with the ground. The upstream fresh water is discharged downstream to regulate the water level. In other words, the high-strength concrete panel is erected and laid on the ground by the expansion and contraction of the airbag, so that water is stored and discharged.

However, according to the pneumatic operation report according to the above-mentioned patent registration No. 367227, the fresh water is gradually increased by the inflow of water continuously flowing from the upstream while the panel unit maintains the target water level by the airbag, thereby leaving the water level. Since it flows over the upper part of the panel part and flows downstream, various sediment accumulates on the concrete of the lower surface of the pneumatic movable beam, whereby the storage water at the lower side of the pneumatic movable beam is not circulated and discharged, and is standing. There is a problem of water decay in the part.

In addition, as one method of avoiding the decay phenomenon of the reservoir, it is thought that the manager periodically checks the fresh water amount and lays down the panel to discharge the reservoir, but at this time, the entire fresh water is discharged downstream through the panel at once. Not only do not maintain the object level, but also after discharging, there is another problem of having to manage the inconvenience of having to store the water up to the object level after the panel part is re-established and the power consumption to lay and raise the panel part.

In addition, both ends of the side wall inclined portion of the embankment and the panel portion must be spaced apart from each other in order to store the water by the panel portion lying down and standing without interfering with the side wall inclined portion of the embankment dam. Due to the water stored up to the target level leaked downstream, there was a problem that a complete reservoir is impossible.

Therefore, while repairing the above problems, the pneumatic operation beam can be installed cheaper and easier in terms of cost and installation, and the pneumatic operation that can prevent the decay of the water by discharging the fresh water stored while maintaining the target level in terms of reliability It is desirable to provide a beam.

An object of the present invention is to provide a storage water discharge device of a pneumatic operation beam to prevent the decay of the storage water by naturally discharged the water flowing to the reservoir while maintaining the target water level irrespective of the amount of inflow upstream. The discharge device forms a discharge port on the upper side of the steel panel, which is erected and laid down by an airbag, and also installs a reservoir discharge pipe from the lower surface of the steel panel to the discharge port position, thereby increasing the inflow amount upstream. Achievement is achieved by naturally discharging the correspondingly depleted reservoir water downstream.

Another object of the present invention is to provide a pneumatic actuating beam which prevents the airbag from contracting and expanding the airbag caused by the vibration of the steel panel which occurs every time the fresh water flows over the steel panel and flows downward. This storage water discharge device is provided by forming an anti-vibration piece at the upper end of the steel panel to maintain the water load applied to the steel panel continuously without time difference when the water overflows. do.

Another object of the present invention is to provide a storage device of the pneumatic movable beam to prevent the leakage of fresh water between the side wall slope of the bank embankment and both ends of the steel panel without interference to the rotation of the steel panel to achieve a complete reservoir. The storage device is folded at both ends of the sealing member having elasticity at one end of the steel panel adjacent to the side wall inclined portion of the embankment bank and fixed in a direction perpendicular to the width, so that the steel panel is erected and laid down. The sealing member is achieved by elastically sealing between the side wall slope of the embankment and both ends of the steel panel without interference with the inclined portion of the embankment at the load operation.

Further objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

The steel panel 20 of the, and from the front lower portion to the upper portion of the steel panel 20 are continuously installed along the direction perpendicular to the width direction at regular intervals to accommodate a plurality of discharge ports (20a) and the upper end is sealed A plurality of storage water discharge pipes 70 having a semi-circular cross section that forms a flow path for raising the fresh water stored therein to be discharged downstream through the plurality of discharge ports 20a, and on both lower ends of the steel panel 20. A pair of coupling rings 22 formed as a hinge to serve as a hinge to form the steel panels 20 and the rotational movement of the up and down, respectively, and the coupling rings 22 of the steel panels 20 are opposed to each other. Both upper surfaces of the part 30 One end is stably fixed with a bolt, and a coupling shaft 42 is formed at the other end, and a pair of fastening seats are fitted into the coupling ring 22 so that the steel panel 20 rotates around the coupling shaft 42. 40 and a rubber material which is fixed along a direction perpendicular to the width direction on the front side of the steel panel and one side of the steel panel in contact with the steel panel to prevent leakage to the contact portion of the steel panel 20 and the steel panel Both ends are folded and fixed in a direction perpendicular to the width direction on the front surface of one end of the two steel panels 20 adjacent to the side wall inclined portion 18 of the bank embankment and the side wall inclined 18 of the bank embankment Sealing member 65 made of a rubber material that is elastically in close contact with the side wall slope 18 of the embankment bank to prevent leakage of water without interfering with the rotation of the steel panel, and irregularities along the width direction at the upper end of the steel panel 20. Continuous into mold The anti-vibration piece 80 keeps the load of water applied to the upper end surface of the steel panels 20 continuously without time lag when the opened and fresh water falls over the top of the steel panels 20 to prevent vibration. And stably fixed to a stool fixed to the upper both sides of the steel panels 20 and the rear bottom concrete 16 surface of the airbag 10 so that the steel panels 20 are temporarily overturned in the opposite direction of the water flow by the counter-wind. A plurality of fall prevention members 90 having a belt shape, such as rubber belts, to prevent them from being made to communicate with the air bag 10 through the bottom concrete 16, the air generated from the air level, discharge device air bag It is composed of the air supply, the discharge pipe 14 to inject and discharge (10) to shrink and expand.

In the above, as shown in Figures 2 to 4, the plurality of anchor bolts (34) embedded in the bottom concrete (16) to penetrate at equal intervals along the longitudinal direction of the base plate body 50 and Compression pieces 32a and 32b are continuously formed to be inclined downward in the vertical direction along the longitudinal direction at both ends, and are fitted to the plurality of anchor bolts 34 and are compressed by tightening the plurality of nuts 34a. 32b) is composed of a plurality of clamping plates 32 which compress both overlapping ends of the airbag 10 to the arcuate protrusions 50a and 50b of the base plate body 50.

Thus, the storage water discharge device of the pneumatic operation beam according to the present invention made in more detail with reference to Figs.

First of all, when water is to be stored at a desired level in a river through a pneumatic movable beam, when the air level and the discharge device, such as an air compressor installed on the embankment, are operated, the air is compressed and the compressed air is buried in the bed concrete 16. The rubber plate body of the airbag 10, which is connected to the base plate body 50 by the clamping plate 32 of the fastening part 30 and the anchor bolt 34, is overlapped by both ends through the air supply and the discharge pipe 14. Since the airbag 10 is gradually inflated by air pressure, the airbag 10 is fixed to the clamping plate 32 of the fastening part 30 by the anchor bolt 34 and the fastening feldspar 40 to be described later in detail. The plurality of steel panels 20 is gradually pushed upstream, that is, in the direction opposite to the water flow.

At this time, the plurality of steel panels 20, as shown in Figures 2 and 3, the coupling ring 22 is formed on both sides of the lower end so as to be rotatable to the coupling shaft 42 of the fastening feldspar 40 made of galvanized steel sheet. As the airbag 10 is inflated, the air shaft 10 is erected and rotated in a counterclockwise direction, that is, in the direction opposite to the flow of water, about the coupling shaft 42 of the fastening feldspar 40 as the airbag 10 is inflated. As the sealing member 65 of the material is elastically in close contact with the side wall inclined portion 18 of the embankment bank, it rotates in the opposite direction of the water flow with the steel panels 20.

In other words, the steel panels 20 are coupled to each other in a row by the water plate body 60 made of rubber, and the load is supported on the coupling shaft 42 of the fastening stool 40 made of metal. In addition, the fastening feldspar 40 is fixed to both upper surfaces of the clamping plate 32 by anchor bolts 34, and consequently the steel panels 20 are pushed upstream simultaneously as the airbag 10 expands. The coupling shaft 42 of the fastening feldspar 40 is rotated in the opposite direction to the water flow. Here, the fastening feldspar 40 may be formed in a single body at a predetermined interval on the clamping plate 32 of the fastening part 30, and in this case, the fastening feldspar 40 may be made of the same material as that of the clamping plate 32. It is desirable to form and galvanize the surface to prevent corrosion.

Then, and when the inflation (ups and downs) of the airbag 10 is completed to correspond to the desired water level, the steel panels 20 are erected perpendicularly to the ground with a sieve supported by the airbag 10, as shown in FIG. Standing up at an angle, the water level is controlled by blocking the water flowing from the upstream. Here, the rubber plate plate 60 is fixed to the front of one side of the steel panel 20 and the front of one side of the other steel panel in contact with the width direction in a direction perpendicular to the width direction to prevent leakage between the steel panel and the steel panel. 1 and 5, the total length of the steel panels 20 and the length of the air bag 10 in the same state for the purpose of completely storing the fresh water without leaking, as shown in Figs. The two members of the steel panel are inflated by the inflation of the airbag 10. When rotating, the watertight sidewalls of the banks and the side wall slopes 18 of the banks are elastically in close contact with each other to seal between the two steel panels 20 and the side wall slopes of the banks. Prevented complete Not made.

As such, the steel panels 20 are erected vertically or obliquely with respect to the ground to maintain the desired water level, and the fresh water is gradually increased by the inflow of water continuously flowing from the upstream. When the water reaches the position of the plurality of discharge ports 20a formed on the upper portions of the 20 or overflows to the upper portions of the steel panels 20, the fresh water stored therein is opened by the hydraulic pressure to the inlets of the plurality of the storage water discharge pipes 70. The water flows through the discharge port 20a of the steel panels 20 to be discharged downstream to prevent fresh water from being circulated.

When the fresh water overflows the upper surfaces of the steel panels 20 because the anti-vibration pieces 80 are continuously cut in a square wave or a sawtooth shape along the width direction at the upper end of the steel panels 20. The anti-vibration piece 80 prevents eddy currents and stagnation and flows stably, thereby contracting and expanding the airbag 10 due to the vibration of the steel panels 20 and the vibration of the steel panels 20. This is avoided. In other words, whenever the fresh water flows over the upper surfaces of the steel panels 20 and falls downstream, the uneven parts of the anti-vibration piece 80 apply the load of the water applied to the upper surfaces of the steel panels 20. It remains constant without time difference and falls downstream, whereby the load applied to the steel panels 20 is constant to prevent vibration.

On the other hand, even if a strong backwind occurs in the state in which the steel panels 20 are raised by the expansion of the air bag 10, a plurality of fall prevention members such as a rubber belt connected to the steel panels 20 and the concrete on the bottom of the concrete (90) Since the steel panel 20 has elastic force and stably holds the steel panels 20 with respect to the airbag 10, the situation in which the steel panels 20 are overturned in an upstream direction, that is, in a direction opposite to the water flow does not occur.

And, in order to discharge the fresh water in the stream, by controlling the nozzle (not shown in the drawing) provided in the air supply, the discharge device to discharge the air of the air bag 10 through the air supply, discharge pipe 14 When the airbag 10 is gradually contracted (coated), and the steel panels 20 supported thereon also rotate the coupling shaft 42 of the fastening feldspar 40 in the direction of water flow along the axis to be horizontal to the ground. It can be laid or beveled. When the steel panels 20 are in a horizontal or oblique state with respect to the ground, upstream fresh water is discharged downstream through the steel panels 20 to adjust the water level.

On the other hand, as a comparative example, unlike the prior art, that is, the manager has to lay down the panel part periodically to discharge the stored water in order to prevent the decay of the fresh water, the present invention provides a discharge port on the upper side of the steel panel, respectively. And, by installing the storage water discharge pipe from the lower surface of the steel panel to the discharge port position, the fresh water is naturally discharged downstream to correspond to the inflow amount of the upstream, and when the fresh water overflows, It can be seen that the formed anti-vibration pieces are discharged downstream by keeping the water load constant without time difference.

In this result, according to the present invention, the object water level is changed by the inflow of water flowing down from the upstream, and when the water flows over the upper portions of the steel panels, the decay of the water is prevented by preferentially discharging the water flowing in the lower flow than the overflowed amount. Of course, the vibration of the steel panels generated during the overflow and the contraction and expansion of the airbag by this vibration is not only prevented, but there is an advantage that the water can not be completely leaked.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.

According to the storage water discharge device of the pneumatic operation beam of the present invention, which is clear from the above description, when the target water level is changed by the inflow of water and flows over the steel panels, By circulating, the water level is prevented while maintaining a constant level of water at all times, and the vibration of the steel panels generated whenever water flows over and falls, and the airbag is prevented from contracting and expanding by this vibration, as well as the side wall of the bank embankment. By preventing leakage occurring between the inclined portion and the left and right steel panels, there is a possible effect of a complete reservoir.
