Description

Water gate reinforcing structural strength and power of stopping water leak}

The present invention relates to a revolving sluice reinforced with structural strength and exponential performance, and more particularly, to reinforce the structural strength of a hydroplate directly subjected to hydraulic pressure so that the slugging does not bend under strong hydraulic pressure, Leakage is not generated through the space between the bottom of the to improve the reliability of the hydrological operation.

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 maintained at a constant 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.

The most representative of these automatic floodgates are the conducting sluice and the bottom discharge sluice. In the sluice sluice, the rotational axis of the sluice is rotatably fixed to the lower part of each supporting structure constructed on both sides of the channel. As a standing gate or a falling gate, it is a sluice that traps or discharges water in the reservoir, and when the sluice is fully opened, the slug comes in close contact with the bottom of the sluice, so it is safe to protect the sluice even when large foreign objects float. There is a drawback to polluting the water quality because it can not discharge the lower layer water in the storage space before opening, the bottom discharge type hydrology is fixed to the upper rotation of the support structure on the top of each support structure so that the water gate is downward by the power means A gate that opens and closes the waterway while rotating or rotating upwards. Although water from the reservoir is discharged through the lower part of the gate, foreign substances in the lower part of the reservoir can be discharged together.However, if the flow rate increases rapidly, such as a flood, large foreign bodies come off the water and hang on the gate. There was a problem that could be broken.

In order to solve the problems of the conductive sluice or the bottom drainage sluice, a rotating sluice has been proposed in such a way that it can have the advantages of the conductive sluice and the bottom drainage sluice. The fan-shaped both side plates 12 are fixed to both side ends of the 11, respectively, and the rotating shaft 13 is drawn outward from the upper one side of the both side plates 12 to form a sluice 10. Rotation shafts 13 are rotatably fixed to support structures (not shown), which are constructed on both sides of the river, and power means such as hydraulic cylinders 40 are connected to the rotation shafts 13, respectively. It is configured to open and close the channel formed between the two support structures while the 10 rotates.

However, in such a general rotational gate, the sluice plate 11 has a plurality of H beams 14 arranged side by side, so that the flat top plate 15 and the rounded lower plate 16 are each inside the H beam 14. When the rotating shaft 13 of the water gate 10 is rotatably fixed to both support structures 20 in the state configured as described above, the middle portion of the water gate 10 is relatively vulnerable to water pressure rather than both sides of the water gate 10. Therefore, if the water gate is no problem for the water pressure to a certain length, but if the water gate 10 is manufactured to a long extent beyond the limit, the middle part of the water gate 10 is bent like a bow by water pressure to operate smoothly. This is not done and there is a problem that the index is not made properly when the floodgate 10 is closed.

The H beams 14 disposed inside the sluice plate 11 are generally three, and two H beams 14 on both sides of the H beams 14 are partially cut off due to the rounded bottom shape of the sluice plate 11. H-beam 14 disposed inside the sluice plate 11 is asymmetric in the up and down direction because it can be fixed to the interior of the sluice plate 11 in this state, the H-beam 14 inside the sluice plate 11 in this way ) Is asymmetrically placed, the ability to withstand hydraulic pressure is much lower than that of symmetrical shapes. In particular, when the length of the water gate 10 is longer than 10 m, the stress due to the water pressure is concentrated in the middle portion of the water plate 11 so that the H beam 14 disposed inside the water plate 11 alone does not endure large water pressure and bends. There was no choice but to lose.

In addition, when the sluice plate 11 is bent, not only the appearance becomes poor, but also the rotation operation of the sluice 10 cannot be made smoothly, and when the sluice 10 is closed, the bottom of the sluice plate 11 and the waterway 21 are closed. There is a problem that a gap is generated between the parts and water leaks through such a gap, so it is inevitable to perform a repair work with a new water gate 10 at a large cost, and even if a repair work is carried out, the structure of the water gate plate 11 is fundamental. As long as the mechanical strength is not improved, the above-described warpage problem of the hydrological plate 11 has to be repeated.

In addition, the most problematic in the general rotational water gate is that the foreign matter such as earth and sand is sandwiched between the water gate plate 11 and the bottom of the waterway 21 to interfere with the rotation operation of the water gate 10, It can be said that the leakage occurs between the water gate plate 11 and the bottom portion of the waterway 21 when closing, up to now, even if the water gate 10 in any form does not solve this problem fundamentally.

The present invention reinforces the structural strength of the hydroplate directly receiving water pressure so that the water gate does not bend under strong water pressure, and does not leak through the space between the water gate and the bottom of the waterway when the water gate is closed, thereby improving reliability of the water gate operation. It is to provide a revolving gate with structural strength and exponential performance to improve.

In order to solve this problem, the present invention places a middle plate inside the sluice plate, and fixes a plurality of channels vertically and symmetrically between the middle plate and the top plate, and a reinforcing rod is formed between the respective channels along the longitudinal direction of the sluice plate. The reinforcing rods are fixed to both sides of the inside of the sluice plate at right angles to the round surface of the lower plate and at the same time as a warranty form along the longitudinal direction of the sluice plate. Therefore, it is fixed in the shape of a warrant to fit the round shape to reinforce the strength of the hydrology plate so that the hydrology plate is not bent under water pressure even if the hydrology plate is composed of a long span structure of 10m or more.

In another aspect, at the bottom of the channel to form a step larger than the rotation radius of the waterway so that the rotational movement of the water gate does not interfere, the packing is fixed to the top of the bottom of the waterway, and based on the opening of the water gate Secure the foreign material prevention plate at the water storage end of the plate so that when the water gate is opened, the foreign material prevention plate is placed on the top of the packing to prevent foreign matter from being caught between the water gate plate and the bottom of the waterway. At the end of the drainage side, a water leak prevention jaw is formed to protrude outward from the bottom surface of the water gate so that the water leakage prevention jaw contacts the packing to prevent water leakage when the water gate is closed.

According to the present invention, the stiffness of the sluice plate is maximized by the symmetrical channel fixed in the sluice plate, the stiffening plate in the shape of the warrus and the stiffening plate in the shape of the war truss. The smooth opening and closing operation can improve the reliability of the hydrological rotation operation, as well as prolong the maintenance period of the hydrological gate, thereby greatly reducing the cost of the hydrological maintenance.

In addition, the packing is fixed to the jaw of the waterway, and the foreign matter prevention plate is fixed to the water storage side of the waterway plate so that foreign matters such as soil and sand can be prevented from entering the space between the waterway and the waterway when the waterway is opened. This can be made smoothly, the water leakage prevention jaw is formed on the drainage side of the sluice plate has the advantage of preventing leakage by contacting the leakage prevention jaw when the seal is closed.

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

In this configuration, the channel 114 is fixed up and down symmetrically in its original shape in the sluice plate 110 so that the force to withstand the water pressure becomes very large, and between the channels 114 between the reinforcing rods ( 115 is fixed in the form of a warren truss to maximize the force to withstand the water pressure, and the reinforcing rods 115 and the reinforcement plate 116 on both sides and the lower side of the sluice plate 110 may be particularly vulnerable Since they are respectively fixed in a warren truss shape toward a direction perpendicular to the round surface of the lower plate 112, the stiffness of both sides and the lower side of the sluice plate 110 also depends on the arrangement of the reinforcing rod 115 and the reinforcing plate 116. It can be maximized.

That is, according to the first embodiment of the present invention, the stiffness of the sluice plate 110 in the overall stiffness by the reinforcing rod 115 is fixed in a warren truss between the channel 114 of the up-down symmetric type, each channel 114 Both sides and the lower side, which can be maximized and vulnerable in the sluice plate 110, can also maximize the structural strength depending on the arrangement of the reinforcing rod 115 and the stiffening plate 116.

Figure 5 is a side cross-sectional view when opening the rotating gate according to the second embodiment of the present invention, Figure 6 is a side cross-sectional view when closing the rotating door according to the second embodiment of the present invention.

As shown, the second embodiment of the present invention prevents foreign matter from entering between the gate 100 and the bottom of the waterway 210 when the gate 100 is opened, and when the gate 100 is closed. In order to prevent the water in the reservoir space from leaking between the water gate 100 and the waterway 210, for this purpose, a step 211 is formed at the bottom of the waterway 210 to form the water gate 100 above it. It is rotatably installed, but step 211 is formed larger than the radius of rotation of the water gate 100 so that the water gate 100 can rotate without interference, the packing 300 on the top of the step 211 of the waterway 210 Fixing, and the support plate 301 is installed on the upper portion of the packing 300 to prevent the packing 300, on the reservoir side end of the sluice plate 110 on the basis of the opening of the water gate 100 The foreign matter prevention plate 310 is fixed to the foreign matter prevention plate 310 when the water gate 100 is opened, the support plate 301 above the packing 300 It is placed so as to prevent foreign matter from being caught between the sluice plate 110 and the step 211 of the waterway 210, the sluice plate 110 at the drain side end of the sluice plate 110 on the basis of the opening of the water gate 100.
