The present invention relates to a pneumatic actuating beam which is installed in a river or a river and secures a low amount by inflating and expanding a rubber beam by injecting and discharging air according to a desired low amount of water. And damage to rubber beams caused by strong impacts with harmful substances such as falling rocks, stones and rubbish while changing the height by changing the height by turning and laying on the ground according to the expansion and long-term water The present invention relates to a main body protection device of a pneumatic movable beam to prevent the aging phenomenon of the rubber beam caused by contact with and exposure to ultraviolet rays.

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 collapsible or inflatable rubber dams are designed to be filled with air for expansion of the rubber beams, and a fixing device for fixing the rubber beams to the concrete and the levee and pipes for supplying or discharging air. Equipment, blowers, and float control 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 beam is directly exposed to the harmful substances coming from the upstream, sharp driftwood or driftwood rolling into the riverbed by falling rocks or strong water pressure in mountainous areas, etc. When the impact from the rubber beam is torn or there is a problem that can not function as a hole or bank embankment.

To this end, in order to cure the above problems, rubber to prevent or damage the rubber beam by blocking the harmful substances such as falling rocks and driftwood from the upstream and falling down from the upstream, It is a situation where a dam is drawn up and installed, for example, it is known by Korean Utility Model Registration No. 187341 (name: body protection device of a rubber dam) registered and elected by the person.

According to the Utility Model Registration No. 187341, the both ends of the rubber plate body is placed on the structure embedded in the bottom concrete, covered with fixing brackets in the longitudinal direction thereon, and then fixed by tightening a nut to the first anchor bolt embedded in the concrete.

Therefore, the object of the present invention is to protect the rubber beam semi-permanently by preventing the damage and aging of the rubber beam caused by strong impacts and scratches from falling rocks, driftwood and stalactites, or due to prolonged ultraviolet exposure and water contact. It is to provide a body protector of the pneumatic movable beam, the body protector is integrally fastened to the front of the rubber beam made of stainless steel or galvanized steel sheet, so that the steel panel is grounded when the rubber beam contracts and expands It is achieved by controlling the water level by rotating the building and lying down, and by preventing the rubber beam from contacting or being exposed to harmful substances, water and ultraviolet rays.

Another object of the present invention is to provide a main body protection device of a pneumatic movable beam to prevent the decay of the stored water by naturally discharge the water flowing to the reservoir while maintaining the target water level irrespective of the inflow amount of the upstream. The protection device forms a discharge port on the upper side of the steel panel, which is erected and laid down by a rubber beam, and also installs a plurality of reservoir discharge pipes from the lower surface of the steel panel to the discharge port position. This is achieved by naturally discharging the stored fresh water downstream to correspond to the inflow quantity.

Another object of the present invention is pneumatic operation to prevent the shrinkage and expansion of the rubber beam caused by the vibration of the steel panel and the rubber beam generated whenever the fresh water flows over the steel panel and flows downstream to the downstream. The main body protection device of the beam is provided with an anti-vibration piece at the upper end of the steel panel to maintain a constant load of water applied to the steel panel through the anti-vibration piece during the overflow of the water and discharge it downstream. Is achieved by giving.

It is composed of

Thus, the body protection device of the pneumatic movable beam according to the present invention made will be described in more detail with reference to FIGS.

In order to store water at the desired level in the river through the pneumatic movable beam and to protect the rubber beam 10 made of the tubular rubber plate 12 from contact with harmful substances, ultraviolet rays and water, first, an air compressor installed on the bank. When the air level, the discharge device is operated such that the air is compressed, the compressed air is overlapped at both ends through the air level, discharge pipe (14) embedded in the bed concrete (16) and the plurality of first clamping plate (2) Since the rubber anchors 10 are supplied into the rubber plate body 12 of the rubber beams 10 that are tightly and coupled to the lower bed structure 1 by the first anchor bolts 3, the rubber beams 10 gradually start to undulate by air pressure. While supporting the front and the rotatably fastening feldspar 40 fixed to the upper surface of the lower plate member 50 is rotatably coupled to the galvanized steel or stainless steel panel 20 of the push upstream It is.

At this time, the steel panels 20 are coupled to each other in a row by the water plate body 60 made of a rubber material and the load on the coupling shaft 42 of the fastening feldspar 40 made of galvanized steel as shown in FIG. 4. 4 and 5, the fastening feldspar 40 is formed of a stainless steel second anchor on both upper surfaces of the second clamping plates 32 of the fastening portion 30 made of a galvanized steel sheet. As a result of being fixed with bolts 34, as a result, the steel panels 20 are simultaneously pushed upstream according to the ups and downs of the rubber beam 10, and counterclockwise about the coupling shaft 42 of the fastening seat 40. That is, while rotating in the opposite direction of the water flow to stand up as shown in Figs. 1 and 3 to cover the front and the upper portion of the rubber beam 10, thereby the driftwood and driftwood flowing down from the upstream by rockfall or strong water pressure Impact of harmful substances such as Since the rubber beam 10 is protected from the scratches, the surface of the rubber beam 10 is not scratched, and the steel panels 20 are blocked in advance so that the water flowing down from the upstream does not touch the rubber beam 10. In addition, the steel panels 20 to completely block or partially block the ultraviolet rays in accordance with the degree of standing or lying down to prevent the aging of the rubber beam (10).

As such, the steel panels 20 are vertically erect or oblique to the ground in a state supported by the rubber beams 10 to prevent harmful substances, ultraviolet rays, and the like, which flow down from the upstream while protecting the rubber beams 10. The water level will be controlled by blocking the water. In this case, the above-described rubber index plate body 60 prevents leakage of fresh water by blocking leakage between the steel panels 20, thereby making a complete reservoir.

And, the steel panels 20 are erected vertically or obliquely with respect to the ground, and the fresh water is gradually increased by the inflow of water continuously flowing from the upstream in the state of maintaining the desired water level so that the steel panel is out of the target water level. 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.

In addition, since the anti-vibration pieces 80 are continuously cut in a square wave or sawtooth shape along the width direction at the upper end of the steel panels 20, fresh water may flow over the upper surfaces of the steel panels 20. At this time, the anti-vibration piece 80 prevents the vortex and the stagnation phenomenon to flow stably, whereby the vibration of the steel panel 20 and the rubber beam 10 due to the vibration of the steel panel 20 by Shrinkage and expansion are prevented. In other words, whenever the fresh water flows over the upper surfaces of the steel panels 20 and falls downstream, the anti-vibration piece 80 constants the load of the water applied to the upper surface of the steel panels 20 without time difference. It keeps to fall to the downstream, whereby the load applied to the steel panels 20 is constant to prevent vibration.

On the other hand, even when strong reverse wind occurs in the state in which the steel panels 20 are raised due to the ups and downs of the rubber beam 10, the fall prevention having a band shape like a rubber belt connected to the steel panels 20 and the bed concrete 16 Since the member 90 has elastic force and stably holds the steel panels 20 with respect to the rubber beams 10, the situation in which the steel panels 20 are rolled upstream does not occur.

And to discharge the fresh water, the air level, the discharge device is controlled to discharge the air in the rubber beam (10) through the air level, discharge pipe 14, the rubber beam 10 is slowly overturned and supported by the steel The panels 20 also rotate the coupling shafts 42 of the fastening feldspar 40 clockwise, i.e., in the direction of water flow, about the axis, so as to lie horizontally or obliquely with respect to the ground, as shown in FIG. The beam 10 is completely enclosed by the steel panels 20 to protect the above-mentioned harmful substances such as falling rocks, stalactites and driftwood from ultraviolet and water contact, and in this state, upstream fresh water The water level is controlled by being discharged downstream on the surface of the steel panels (20).

On the other hand, as a comparative example, the old technology, that is to say that the seat cover is exposed to water and ultraviolet rays for a long time, the aging is accelerated, and also damaged with the rubber beam by the impact of harmful substances such as falling rocks, stalactites, driftwood, etc. In contrast, the present invention is a steel panel made of galvanized steel or stainless steel is installed in front of the rubber beam at regular intervals, and the water is stored and rotated according to the ups and downs of the rubber beam. It can be seen that during discharge, harmful substances such as falling rocks, sharp rocks and driftwood are blocked as well as UV and water contact.

In this result, according to the present invention, by protecting against strong impacts from falling rocks, driftwood and stalactites, exposure to ultraviolet rays, and contact with water in advance, the rubber beams are prevented from being damaged and deteriorated, thus functioning as a bank for embankments. It is possible to maintain for a long time, and to prevent the economic loss and life-saving accidents caused by breakage of the rubber beam, and also to prevent the corruption of the stored water by circulating the fresh water stored downstream to circulate.

According to this application example, it is possible to provide the main body protection device of the pneumatic movable beam which is simpler in structure, and the main body protection device of the pneumatic movable beam which is more stable in terms of reliability.

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 main body protection device of the pneumatic movable beam of the present invention, which is evident from the above description, the steel panels made of galvanized steel sheet or stainless steel are installed on the front side of the rubber beam, so that the rubber beams are erected and laid down according to the ups and downs of the rubber beams.
