The present invention relates to a movable beam installed across a river, a river, and the like to adjust the water level, and more specifically, the height is increased by the rotational action of standing and lying on the ground by the linear movement of the cylinder rod. Integrate the panel to change the water level and the support that pivots it to the ground with fiber-reinforced composite material, providing the ease of installation when installing the movable beam, while the elasticity of the rotation range of the panel due to the rotational movement of the hydraulic cylinder The present invention relates to a hydraulic movable beam for achieving convenience in maintenance according to application and structure simplification.

In addition, the present invention relates to a hydraulic movable beam to more secure the watertight between the panel and the panel or successively installed between the panel and the riverbed concrete to be installed by the width of the river or river.

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 amount of water and install it easily and to control the height of the rubber dam 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 (airbag), and the fixing device for fixing the airbag to the riverbed concrete and the levee and the pipe for supplying or discharging the air. Equipment, blowers, float valves for level control, and the like.

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 overturned, the panel portion supported by the airbag rotates in the direction of the flow of water around the rotational axis so as to be horizontal to the ground. As a result, the upstream water is discharged downstream to adjust the water level. In other words, the high-strength concrete panel is undulated and inflated by the expansion and contraction of the airbag, so that water is stored and discharged.

However, according to the pneumatic movable beam according to the above-described patent registration No. 367227, the high strength concrete panel part, the support for supporting it, and the stopper for limiting the rotation range of the high strength concrete panel part are separated, respectively, and the base plate of the river bottom. Due to the fixed installation, the work efficiency is extremely reduced compared to the increase of manual labor, and because of the complicated structure, it is difficult to maintain the movable beam and the installation cost is increased by using expensive airbags in the width direction. .

In addition, since the closed part is made of concrete, the load is heavy, and when the airbag is standing up, the compressor is heavily loaded, which causes a lot of electrical loads, which in turn causes expensive electrical loads. There is a problem that the airbag may burst or the concrete panel part may be broken.

In addition, the watertight structure between the panel and the panel and between the panel and the base plate is not strong, so that water leaks to this boundary.

Therefore, it is desirable to provide a hydraulic movable beam that is easy to install and maintain by repairing the above problems while allowing a cheaper hydraulic movable beam to be installed in terms of facility cost and a panel and hydraulic cylinder in a simpler manner in terms of reliability. Do.

Accordingly, it is an object of the present invention to provide a hydraulic movable beam that provides convenience of construction and maintenance by integrating a panel that pivots up and down on the ground and a support for rotatably coupling it to the ground. , Hydraulic movable beams are achieved by integrating a plurality of supports installed in the riverbed concrete direction and a plurality of panels that are pivotably coupled to the support with a fiber-reinforced composite material having light weight, corrosion resistance, high strength, and high durability. do.

Thus, the hydraulic movable beam according to the present invention made will be described in more detail with reference to Figs.

First, as shown in FIG. 7D, when the plurality of panels 10 are to be erected to store water in a state where the plurality of panels 10 are lying on the bottom of the stream, the hydraulic cylinder ( When the hydraulic pressure of the 50 is discharged and the rod 50a is pulled toward the cylinder, the roller 34 of the driven part 30 coupled to the tip of the rod 50a is applied to the lower plates 12 of the plurality of panels 10. The first link member 32 connected to the first joint 32a is pulled while moving toward the hydraulic cylinder 50 along the pair of guide rails 31 coupled thereto.

As shown in FIG. 7D, the first link member 32 is coupled to the second joint 32b with a slight inclination to the second link member 33 in a state where the plurality of panels 10 are completely laid on the floor. Therefore, as the rod 50a of the hydraulic cylinder 50 moves backward, the first link member 32 rotates counterclockwise with the second joint 32b as the axis, while the second link member 33 In addition to being folded toward the) side, the plurality of panels 10 are gradually pushed upstream, that is, in the direction opposite to the water flow. Here, since the second link member 33 receives the force in the vertical direction by the first link member 32, the second link member 33 continues to be horizontal with respect to the ground.

Subsequently, the plurality of panels 10 made of a reinforcing fiber composite material, that is, a reinforcing fiber selected from glass fiber, carbon fiber or aramid fiber and a resin selected from polyester, vinyl ester, phenol, or epoxy are shown in FIG. 2. As shown, the first joint member 22 of the support 20 made of a fiber-reinforced composite material is formed in each of the spherical cross-sectional ball joint (10a) is formed at the lower end of one side of the upper plate 11 and the lower plate 12 ) And the first and second recesses 22a and 24a formed by the second capture member 24 so as to be rotatable, the first and second capture members are rotated counterclockwise. The first and second grooves 22a and 24a of the members 22 and 24 are erected while gradually rotating in the opposite direction of the water flow.

In other words, as described with reference to FIGS. 4 and 5, the above-described panels 10 have first and second long axis grooves 13a respectively disposed at the outer upper side and the lower side of the left and right side walls 13 and 14, respectively. 14a) is formed in an asymmetrical direction and has upper and lower extension plates 18 and 19 having one and second fastening pieces 18a and 19a at one side edge of the upper plate 11 and the lower plate 12, respectively. Since they are formed to extend in mutually asymmetric directions, as shown in FIG. 5 when combined with the neighboring panels, the first and second long axis grooves 13a, 14a, and the first and second grooves of the panel 10 are shown. 2 The plurality of panels 10 as shown in FIG. 4 by matching the first and second fastening pieces and the first and second long axis grooves of the panels adjacent to the fastening pieces 18a and 19a and then pushing them vertically downward. Since they are coupled in a line without a gap, leakage occurring between the panel and the panel is prevented.

The plurality of panels 10 coupled by the sliding method are supported by the first capturing member 22 of the support 20, and the first and second capturing members 22 of the support 20. The 24 is fixed to the lower concrete 60 by the anchor bolt 28, and as a result, a plurality of panels in accordance with the counterclockwise rotation of the first link member 32 by the backward movement of the rod 50a 10 rotates counterclockwise, i.e., opposite to the flow of water, about the first and second recesses 22a and 24a of the first and second capture members 22 and 24 while simultaneously pushing upstream. do.

When the lower ends of the panels 10 come into contact with the front ends of the second capture members 24 serving as stoppers, the rotation of the plurality of panels 10 is stopped, and the first link member 32 also has a second link. By stopping the rotation at right angles to the member 33, as a result, the panel 10 described above is erected obliquely with respect to the ground in the state supported by the driven portion 30, as shown in FIGS. 3 and 7A. The water level is controlled by blocking the water flowing downstream from. Here, the angle formed by the arc of the first recess 22a of the first capturing member 22 and the arc of the second recess 24a of the second capturing member 22 is 135 ° with respect to the central axis of the arc. desirable. Therefore, the plurality of panels 10 are erected at an angle to the ground or laid horizontally within the rotation range of 135 ° with respect to the water flow direction to adjust the water level.

As such, the hydraulic pressure applied to the panel 10 and the hydraulic pressure of the hydraulic cylinder 50 to control the panel collide with each other during the construction of the plurality of panels 10, and the extreme fluctuation is caused by the action of the very fluid hydraulic pressure. Will occur. This phenomenon is absorbed by both of the first and second joints 32a and 32b, which are freely rotated up and down, so that the joints are not damaged, and the first and second link members 32 and 33 are not generated. The first and second link members 32 and 33 are both hydraulically absorbed to the hydraulic cylinder 50 while absorbing all the shocks and continuing to apply the hydraulic pressure continuously downstream in the upright state of the panel 10. Since the force is not transmitted, the force for maintaining the pressure of the hydraulic cylinder 50 is not necessary, and thus it is possible to extend the durability.

On the other hand, the plurality of panels 10 mentioned above are erected at an angle 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, thereby leaving the panel 10 beyond the target water level. In the case of overflowing the upper part of the plurality of panels, water may flow into the first and second tubes 16 and 17 of the plurality of panels 10, but at this time, as shown in FIG. 3, the plurality of panels ( Rubber packing 40 is forcibly fitted to the top of 10, i.e., the first and second tubes 16 and 17, to maintain watertightness, as well as preventing water from flowing into the panels 10. When the overflowed water drops through the upper part of the panels 10, air is supplied to the rear of the panels 10 by the plurality of rubber packings 40, so that the rear of the panels 10 do not become a vacuum state so that the pulsation of the water is prevented. It will not occur.

2 and 3, one end of the rubber sheet 26 is sandwiched and fixed between the first and second capture members 22 and 24 of the support 20, and the other end thereof is the second capture member. The first and second capturing members 22 and 24 and the panel 10 are held in close contact with the surface of the upper plate 11 of the plurality of panels 10 to maintain watertightness. The leakage between the ball joints 10a of the teeth is prevented.

And when to discharge the fresh water in the river or river in the state as shown in Figure 7a to operate the hydraulic cylinder 50 through the hydraulic pressure to discharge the rod (50a) driven parts coupled to the tip of the rod (50a) The first link connected to the first joint 32a while slowly moving forward along the pair of guide rails 31 coupled to the lower plates 12 of the plurality of panels 10 by roller 34 of 30. By pushing the member 32 upward, the second link member 33 coupled to the first link member 32 and the second joint 32b to maintain a right angle is shown in FIGS. 7B and 7C. As described above, the plurality of panels 10 are gradually pulled in the clockwise direction, that is, the water flow direction by vertically upward movement and oblique movement with respect to the axis of the second fixing member 36 as much as the discharge length of the rod 50a.

In addition, when the first and second link members 32 and 33 are unfolded in parallel with respect to the second joint 32b, the plurality of panels 10 may also be first and second of the support 20. The grooves 22a and 24a are rotated in a clockwise direction, that is, in a water flow direction, with respect to the axis, so that they are horizontally or obliquely placed with respect to the ground as shown in FIG. 7D. When the plurality of panels 10 are in a horizontal or oblique state with respect to the ground, upstream fresh water is discharged downstream through the plurality of panels 10 to adjust the water level.

On the other hand, unlike the prior art, that is to say that the air bag and the high-strength concrete panel part to be installed separately in the concrete of the river, the present invention is integrated with a plurality of panels and the support made of fiber-reinforced composite material to be able to rotate. As a result, it can be seen that a plurality of panels are rotated with respect to the ground with respect to the ground according to the linear movement of the hydraulic cylinder to adjust the water level.

As a result, according to the present invention, a plurality of panels and a support are integrated into a fiber-reinforced composite material having light weight, corrosion resistance, high strength, and high durability, and the panel and hydraulic cylinder are driven by a link member and a joint. In combination, it can be seen that the water level is adjusted by rotating the plurality of panels in stages.

As a result, according to the present invention, a plurality of panels made of a fiber-reinforced composite material and a support body have an integrated structure, and the panels are coupled to a movable part for diagonal and rotational movement, thereby installing and dismantling the movable beam. When the operation and maintenance is easy, and also by fitting the panel and the neighboring panels in a sliding manner, the watertight between the panel and the panel or between the panel and the bed concrete is more robust, there is an advantage that the leak is prevented.

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 should fall within the appended claims of the present invention.
