The present invention relates to a prefabricated automatic floodgate, and more particularly, the assembly of a separate hydrology and support structure can be easily assembled to the guide frame installed in the river, as well as the guide frame and the hydrology and support structure The lifting cylinder is connected between the assembly so that the gate and the supporting structure are lifted by the lifting cylinder to be driven by the bottom discharge type.

As is well known, in order to store water for farming or industrial use, or to purify polluted water quality, the waterway or the waterway of rivers, reservoirs, etc. Will always be at a certain height.

Since conventional underwater beams are mostly installed in a fixed manner, the inflow water is discharged in an overflowing manner to the upper part of the underwater beams, so that contaminants contained in the stored water continuously accumulate at the bottom of the reservoir side, and sedimentary sludge accumulates. This causes problems of secondary pollution, such as the occurrence of pathogenic bacteria or pests.

In view of this, a water gate selectively opens and closes between waterways, and recently, a number of automatic water gates are automatically installed to open and close automatically by driving a power means such as a cylinder according to the water quantity or water pressure of the water reservoir.

Such automatic beam sluice includes a conductive sluice which discharges the stored water to the upper part of the sluice while the supporting shaft of the sluice is located at the lower side of the supporting structure and is inverted according to the water level. There is a floating gate that discharges the stored water to the bottom of the gate.

In the case of conducting hydrology, the siphon passage is provided in the hydrologic gate so that it cannot discharge the subsurface water such as sedimentation sludge before it is completely discharged because the water cannot be discharged to the lower part of the hydrologic gate. Or, it may form a drain to selectively open and close on the lower side of the water gate, but in this case, the amount of drainage is very small, and foreign substances having a width larger than the width of the siphon passage or the drainage port may not be discharged. If the water level rises rapidly due to various factors, it is not able to cope quickly, causing damage to the floodgate and flooding of the river. In addition, in the case of a fish having a regression to find the place where they were first born to go up the river to lay eggs, there is also a problem that the ecosystem is destroyed because the fish can not go up the river in the closed gate.

In addition, in the case of a floating floodgate operates as a bottom discharge type, but when the water increases rapidly, such as a flood, large foreign matters such as tree branches float out together, which may cause the floodgate to be damaged by such a large foreign matter.

In addition, when installing the general conductive hydrofloating or floating hydrologic gates in the same place as the river, it was necessary to install all the supporting structures, the hydrologic gate, and the hydrologic drive device in the state of blocking the river, so the construction was very difficult and the construction period was very long. Losing was a drawback.

The present invention has been proposed in view of this point, and the water gate and the support structure are separately manufactured, and only the guide frame is installed in the river to be assembled to the size of the support structure, and then the water frame and the support structure are assembled into the guide frame. It is intended to provide a prefabricated automatic security door that can be made very simple and shorten the construction period by providing a customized construction.

In another aspect, by connecting the lifting cylinder between the gate and the supporting structure and the guide frame to raise the gate and the supporting structure by the lifting cylinder, water stored in the lower side of the gate can be discharged to prevent contamination of the river. It would be.

Hereinafter, the present invention will be described in detail with reference to the disclosed embodiments and accompanying drawings.

As shown, the prefabricated automatic floodgate according to the present invention is each support shaft 11 drawn out to both sides of the lower door 10 is rotatably connected to the support structure 20, each support shaft 11 It is connected to the power means (not shown) for opening and closing the water gate 10 is configured to discharge or confine the water while opening and closing operation according to the amount or water pressure of the water storage space side in contact with the water gate (10).

"자 형상으로 서로 연결된 가이드프레임(30)을 설치하며, 각 지지구조체(20)와 수문(10)의 결합체를 가이드프레임(30)의 가이드부(31) 안쪽 공간에 상부로부터 삽입하여 구성한 것이다.According to the present invention, in each of the automatic beam gates, each support structure 20 is configured as a single structure separate from the stream on which the automatic beam gates are installed and rotatably connected to the support shafts 11 of the gate 10, respectively. In the river, the flat portion “c” shaped guide portions 31 are positioned to face each other so as to be in close contact with the outside of the support structure 20, and the lower portion of each guide portion 31 is disposed on the front surface by the support plate 32.

"Install the guide frame 30 is connected to each other in the shape of a, it is configured by inserting the combination of each support structure 20 and the sluice 10 in the space inside the guide portion 31 of the guide frame 30 from the top.

At this time, each support shaft 11 of the sluice 10 is drawn out to the outside of the support structure 20, the sleeve 42 is fitted to each support shaft 11, each guide frame 30 guides Receiving spaces 33 are formed at the support shaft corresponding positions of the part 31 to accommodate each of the supporting shafts 11, and the lifting cylinders 40 are fixed to the upper sides of the receiving spaces 33, respectively. The lower end of the piston rod 41 of the cylinder 40 is respectively fixed to the sleeve 42 fitted to each support shaft 11 is configured to lift the combination of the support structure 20 and the water gate 10 as a whole.

In addition, the support structure contact portion and the hydrological contact portion of the guide frame 30 is provided with water-reducing members 34 and 35, such as rubber packing, respectively, so that the support structure 20 and the water gate 10 of the guide frame 30 are provided. When the assembly is assembled, the guide frame 30 and each support structure 20 or between the guide frame 30 and the water gate 10 is configured to be in close contact with watertightness, the discharge side of each support structure 20 and the guide frame Discharge spaces 21 and 36 are formed on the discharge side wall of the 30, respectively, so as to smoothly discharge the foreign substances.

In addition, the guide frame 30 is composed of a separate structure to be settled in a concrete structure forming a weir, or may be formed integrally with a concrete structure forming a weir, on the drawing the guide frame 30 as a separate structure It is shown by taking an example of being placed in a concrete structure consisting of a dam.

Reference numeral 43 in the drawing represents a fixing plate for fixing the lifting cylinder 40 to the upper portion of the receiving space (33).

The lifting type multi-layer automatic guard according to the present invention configured as described above functions as follows.

First, when the amount of inflow is not large, as shown in FIG. 4, the watermark 10 is closed to close the watermark member 35 and the watergate 10 attached to the support plate 32 of the guide frame 30, and the guide frame 30. Water is continuously filled in the reservoir by closely sealing the watertight member 34 attached to each guide part 31 of the c) and each support structure 20.

In addition, when rain or sewage increases, the amount of inflow increases, and when a lot of water is filled in the reservoir, the water gate 10 is rotated by driving a power means that provides power to the water gate 10, and each of the water gates 10 is rotated. Since the support shaft 11 is located below the support structure 20, the water in the reservoir space is discharged upward of the sluice 10 to maintain the water level of the reservoir space at an appropriate level.

By the way, when the quantity is very large and the water pressure is very large, such as flooding, the pressure on the water gate 10 by itself is applied, and the branches or foreign matters collide with the water gate 10 while hitting the water gate 10 by the impact. In this case, the water gate 10 may be completely inverted as shown in FIG. 5 so as to contact the support plate 32 of the guide frame 30 so that the water is discharged upward of the water gate 10 so that the water level may be increased within a short time. It maintains the proper, as well as to secure the water gate 10, and furthermore, since the discharge space 21, 36 is formed on the discharge side of each support structure 20 and the discharge side wall of the guide frame 30, respectively When foreign matter having a large volume, such as a twig, is discharged upwards of the water gate 10, it may be smoothly discharged without being caught by the support structure 20 or the guide frame 30.

At this time, the power means for providing power to the sluice 10 can be automatically operated according to the detection signal transmitted from the flow rate sensor or the water level sensor installed on the reservoir side, but may also be manually operated.

On the other hand, in the process of filling water into the reservoir space, indispensable sedimentary sludge or foreign matter accumulates in the lower layer, so as to discharge it, the lifting cylinder as shown in FIG. 40 is contracted, and when the lifting cylinder 40 is contracted, the piston rod 41 is pulled and the sleeve 42 fitted to each support shaft 11 is pulled, thereby supporting each support shaft 11. Each of the supporting structures 20 and the water gate 10 which are rotatably connected are raised at once, so that the support plate 32 and the water gate 10 of the guide frame 30 are opened to thereby discharge the lower floor water of the reservoir. As a result, foreign substances including sedimentation sludge are discharged together to prevent pollution of the river.

In addition, when the assembly of the support structure 20 and the sluice 10 moves up and down according to the expansion and contraction of the lifting cylinder 40, the sidewalls of each support structure 20 face each other of the guide frame 30. Since it can be guided while sliding contact with the inner space of the guide portion 31, it is always possible to move up and down only in a predetermined position without being separated.

Then, when the combination of the support structure 20 and the sluice 10 is raised to open between the support plate 32 of the guide frame 30 and the sluice 100 above it, a fish is naturally formed and the fish upstream through the space. It also has the advantage of maintaining natural ecosystems.

In addition, it is apparent that each lifting cylinder 40 is automatically adjusted according to the water level of the storage space, the flow rate of the inflow water, the inflow water amount, etc. to finely adjust the drainage amount.

In addition, although not described in the detailed description of the present invention, the guide frame 30 may be configured by placing it here when constructing a dam through a concrete structure in a river and then separately manufacturing it as a separate structure, and constructing a dam. When forming the form of the guide frame as described above can be formed integrally with the weir and the guide frame 30, in addition to any method that can perform the same function as described above, any such deformable implementation Examples are obviously within the scope of the present invention.

In addition, the lifting cylinder 40 is illustrated as a device for lifting and lowering the combination of the support structure 20 and the sluice 10. In addition to the cylinder, the support structure and the sluice are also combined by a screw, a rack-pinion, a crank, and a cable traction device. Since it is possible to raise and lower the respective embodiments are obviously belong to the scope of the present invention.

As described above, the present invention can be completed by simply assembling the support structure and the sluice in the guide frame in a state in which only the guide frame is installed in the river, and the support structure and the sluice are separately manufactured. The construction is very simple and the construction period can be greatly reduced.

In addition, it is possible to finely control the drainage according to the situation by manipulating the water gate according to the quantity or water pressure of the water storage side, and even if a natural disaster such as a flood occurs, the water gate is completely inverted to support the guide plate of the guide frame. By keeping it in close contact, you can protect the water gate safely.

In addition, when foreign matter such as sludge accumulates in the lower part of the reservoir, the lifting cylinder is driven to raise the combination of the supporting structure and the sluice at once, so that the space between the water gate and the supporting plate of the guide frame is separated and the sedimentary sludge together with the lower stratum water. It is possible to discharge the foreign substances together to prevent the pollution of the river, and the fish can move through these spaces can act as fishery.
