The present invention relates to a slide-type automatic sluice, and more particularly, even if foreign matter is caught in the rail for guiding the sliding opening and closing of the sluice, the sluice can operate normally by opening and closing the sluice and the closed and open state of the sluice. The present invention relates to a slide type automatic sluice capable of fine adjustment to prevent deformation and breakage of parts due to the force applied from the sluice.

In general, a hydro gate is a movable structure installed in a waterway or a reservoir to block water or to control a flow rate, and is used to control the flow rate by installing it at a classification point or confluence point of a river, and to prevent backflow of tides by installing on a coastal dike. It is also used for exclusion, ship operation, etc., and it is used to discharge or control flood by installing in flood water discharge or waterproof pipe of dam.

The water gate according to the prior art can be largely divided into a bottom discharge gate and a conductive gate. In the conventional bottom discharge gate, the rod side end of the cylinder portion is hinged by the water gate and the rod pin while the cylinder portion is exposed to the outside of the gate. The other end of the cylinder portion is configured to be hinged by the side support and the cylinder head pin, and the water gate is opened and closed by using the water hinge hinge axis as the rotation axis, but such a water gate is the entire cylinder cover portion and the water gate protruding outward. The structure obstructs the flow of water into the floodgate or waterway during flooding, and in particular, when the water flows out due to the increased flow rate during flooding, many floats (tree roots, foreign objects) floating upstream are caught in the cylinder cover and the entire floodgate structure. Not only further impede the flow, but even this makes it difficult to open and close Door there is a problem that also acts as a cause of the failure.

In order to improve the above problems, a conductive groove was created to make the cylinder groove downstream of the tuft / beam and to open and close the upper end of the water gate by using the water shaft hinge shaft installed at the bottom of the water gate as a rotation axis according to the change in flow rate.

This method eliminated the factors that hindered the operation of the floodgate or caused the flow rate to drop, but this structure prevents the cylinder from running smoothly because sand accumulates in the cylinder grooves installed downstream of the stack. There is a problem that the door can not be opened and closed, and also because the earth and sand flowing down from the upstream of the pile / beam accumulates in the beam, there is a problem that should be dredged regularly.

In order to solve such a problem, there is a hydrology filed in Patent Application No. 2004-21829.

According to the water gate, the sliders respectively installed on the top, bottom, left, and right sides of the water gate move along the rails to open and close the water gate, but foreign matter may be caught inside the inclined portion of the rail, but foreign matters accumulated in the rail may be removed. Since there is no structure, movement of the slider is constrained by foreign matters caught in the rail, so that the slider does not move smoothly, so the bank is not closed tightly, and an overload occurs, causing parts to be damaged.

Then, when constructing the water gate, the hydraulic pressure of the hydraulic cylinder for opening and closing the water gate is set, and for example, an index ring which is installed on the waterway side facing the water gate and seals the waterway in the closed state is applied from the water gate. A certain pressure (pressure for watertighting the waterway) is applied by force to set the watertight watertightness while elastically deforming. However, since the force transferred from the hydrologic main body is different according to the water pressure of fresh water, there is a problem in that a great pressure is applied to the hydrostatic ring for watertightness of the waterway and the shafts of the hydrostatic ring and the hydrologic main body are broken.

The present invention is to solve the above-mentioned conventional problems, while the foreign matter is not caught in the interior of the rail for guiding the opening and closing of the sluice, while the foreign matter is caught in the rail slide type automatic to remove during the opening and closing operation of the sluice The purpose is to provide a sluice.

In addition, another object of the present invention is to prevent the damage of the material by fine-adjusting the fully open and completely closed state of the slide-type automatic hydrologic main body.

Slide type automatic sluice according to the present invention for achieving the above object is characterized in that the movement direction of the slider for guiding the opening and closing of the sluice includes a scraper for removing foreign substances while moving along the inside of the rail when opening and closing the sluice. .

And, the present invention is characterized in that it further comprises a stopper for setting the position where the water gate is fully open and fully closed.

It may be composed of a first blade 420 to scratch the foreign matter (W1) accumulated in the. At this time, although the angle of the first rail 110 is fixed, but the sluice body 200 is sliding while the angle is changed, the first blade 420 may always be disposed inside the first rail 110. The fixing unit 410 is rotatably coupled to the first shaft 210 in place through a bearing.

Figure 5a is a perspective view showing another example of the scraper 400 according to the present invention, Figure 5b is a view showing the operation of the scraper 400 according to Figure 5a.

As shown in FIGS. 5A and 5B, the scraper 400 may be configured to remove the foreign material caught in the first rail 110 when the sluice body 220 is opened. The second blade 430 may be provided to remove the foreign matter W2 accumulated on the movement path of the 211.

The first and second blades 420 and 430 may be integrally formed with the fixing part 410, or may be separately formed through different fixing parts.

That is, according to the present invention, the first and second (420, 430) by scraping the inner wall of the first rail 110, respectively, when the sluice body 200 is closed and opened to remove the foreign matter accumulated on the first rail (110) One slider 211 may move normally.

In addition, the space between the first body 420 and the first body 420 is closed on one side of the first body 420 so that foreign matter is not caught between the first body 420 and the water main body 200. The blocking portion 440 may be further formed. The blocking part 440 may be made of an elastic material such as rubber so as to be curved to cover the outer circumference of the sluice body 200 and elastically deformed according to an angle change of the sluice body 200.

As shown in FIG. 2, the present invention is equipped with stoppers 500 and 600 for adjusting a position in which the hydrologic main body 200 is completely closed or fully open.

The stoppers 500 and 600 are screwed to both end portions (when fully closed and fully open) of the second rail 120, respectively, and are coupled to the front ends of the bolts 510 and 610 and the bolts 510 and 610, respectively. ) Is composed of stopper plates 520 and 620 that constrain the movement of the second slider 221 when fully closed or fully open.

The action of the hydrological according to the present invention configured as described above is as follows.

1. Stopper setting.

When the hydrology is installed on the embankment 10, the hydrologic main body 200 is operated to completely close the waterway 11. When the hydrological main body 200 is closed and contacts the not-shown water ring, the elastic deformation of the water ring is performed. After checking that the index ring is elastically deformed under the set pressure, the water stop body 200 is stopped and the first stopper plate 520 of the first stopper plate 520 operates the first stopper plate 520 to operate the water body. The movement of the 200 is stopped. On the contrary, the hydrological main body 200 is operated to completely open the water channel 11, and when the hydrological main body 200 is opened and contacts the index ring not shown, the elastic ring of the index ring is checked and the index ring is set. When the elastic deformation under pressure stops the operation of the sluice body 200 and operates the second bolt 610 of the second stopper 600 to stop the movement of the sluice body 200 by the second stopper plate 620. do.

2. Upon opening.

The sluice body 200 is disposed in parallel with the first rail 110 to close the channel 11 of the embankment 10, and the stopper flap of the first stopper 500 in a state where the sluice body 200 is completely closed. The site 520 supports the hydrologic body 200. The blade 420 (or the first and second blades 420 and 430) covers the first slider 211 to prevent foreign matter from accumulating.

When the hydraulic cylinder 300 is operated for drainage of fresh water in the closed state of FIG. 2, the rod 310 is gradually inserted to pull the second shaft 220, and the hydrologic main body 200 includes the first and second sliders ( The channel 11 is opened while sliding under the guidance of 211 and 221. Since the opening and closing operation by the sluice body 200 is the same as the known one, a detailed description thereof will be omitted here, and only the novel operation according to the present invention will be described.

When the second blade 430 is applied, foreign matter accumulated in the first rail 110 is removed to the outside of the first rail 110 by the second blade 430 when the sluice body 200 slides downward. One slider 211 slides smoothly.

When the sluice body 200 is fully open, the second slider 221 is in contact with the second stopper plate 620 and no longer moves, and the water channel 11 is fully opened (see FIG. 6).

3. When closed.

In the state of FIG. 6, when the hydraulic cylinder 300 is operated to close the water channel 11, the rod 310 is pulled out and the second shaft 220 is pushed to slide the hydrologic main body 200 upward. As such, the first blade 420 slides along the inside of the first rail 110 and the foreign matter accumulated in the first rail 110 is removed to the outside of the first rail 110 while the sluice body 200 slides upward. do. When the sliding of the water main body 200, the scraper 400 is always fixed inside the first rail 110 even if the fixed portion 410 is rotatably coupled to the first shaft 210, even if the angle of the water body 200 changes. You can move along.

When the water body 200 is completely closed, the second slider 221 is in contact with the first stopper plate 520 and no longer moves, and the water channel 11 is completely closed (see FIG. 2).

As described above, according to the slide-type automatic sluice according to the present invention, even if foreign matter accumulates inside the rail for guiding the opening and closing operation of the sluice body, the foreign matter is removed to the outside of the rail by a scraper so that the slider moves normally along the rail. As a result, malfunctions of the hydrologic body do not occur and material damage does not occur due to congestion.

In addition, since the hydrologic main body can be kept fully open and fully closed through fine control of the hydrologic main body, it is possible to prevent damage such as an index ring and an axis, and to improve the watertightness of the channel.

While the invention has been described and illustrated in connection with a preferred embodiment for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is shown and described.
