LONG SPAN TURNING TYPE FLOODGATE}

The present invention relates to a sewing machine having a fixed frame disposed in a direction transverse to a stream of a river to block river water flowing upstream from the stream and a conductive operation including a water gate arranged so that a lower end thereof is linked to the fixed frame, And more particularly, to a movable spiral beam of a long span type for controlling the water level of a wide stream.

In general, weir refers to a kind of clam fence that regulates the water level of rivers and reservoirs, which plays a very important role in securing agricultural, industrial and domestic water, and is now widely used. In addition, if several beams are installed in the river where the dam can not be installed, it can be used as an alternative structure of the dam because the water level and the quantity can be adjusted.

The types of beams are divided into high information and moving beams, and moving beams are divided into high beam beams and mechanical beam beams. Generally, in order to use for agricultural or industrial water, or to reduce the damage of flood damage, various kinds of waterways are installed in various related waterways such as rivers and rivers such as manual, automatic, semi-automatic or a combination thereof.

The present invention has a plurality of cylinder portions (10) behind the water gate (2), in particular, for widening and conducting wider waters without warping, and the cylinder portion (10) A cylinder 12 disposed at a lower end portion of the cylinder bracket so as to be rotatably linked to the cylinder bracket and a piston rod 13 drawn into and withdrawn from the cylinder do.

As shown in FIGS. 1 to 3, the cylinder brackets 11 are arranged to protrude upward from the bottom surface of the stationary frame 1 in a pair, and have through holes formed therein.

The cylinder 12 is formed with a fastening hole corresponding to the through hole at the lower end thereof, and the lower end thereof is fitted into the inside of the cylinder bracket 11 and is linked by the fixing pin.

The piston rod 13 is inserted into and withdrawn from the cylinder by hydraulic pressure supplied from the outside.

4 to 6, the end portion of the piston rod 13 is coupled to the rear surface of the water can so as to raise and lower the water gate 2 by the cylinder portion 10, According to the embodiment of the present invention, the variable link portion 20 is disposed so as to be rotatable on the rear surface of the watercraft, and the end portion of the piston rod 13 is fastened to one end of the variable link portion.

The variable link portion 20 includes an opening 21 formed in an upper portion of the rear surface of the watercraft, a fixed shaft 22 installed in the opening, one end linked to the fixed shaft, And a variable link 23 linked with the end of the link.

The fixed shaft 22 is provided with an opening 21 at an upper portion of the rear surface of the water gate 2 and horizontally installed inside the water gate 2 through the opening 21, It is preferable to further include a fixed rib that supports both sides and is welded to the water gate.

One end of the variable link 23 is linked to the fixed shaft and projects to the rear of the water tunnel. A through hole is formed at the other end of the variable link 23 to be linked with the end of the piston rod 13.

In addition, the variable link 23 is preferably formed with a protrusion 24 so that the inner edge of the variable link 23 can be brought into close contact with the upper portion of the opening of the water gate when the variable link 23 is turned forward.

That is, both ends of the variable link 23 are linked to the fixed shaft 22 and the piston rod 13, respectively, and the contact protrusions 24 project laterally from one end of the variable link 23 , And are integrally formed in the shape of an overall "┓" shape.

Therefore, when the variable link 23 is pivoted forwardly of the water inlet, the inner edge of the contact projection 24 comes into contact with the opening 21, (A) of the upper side water gate 2 of the water tank 2.

Therefore, when the water gate is raised or turned, the inner edge of the contact projection 24 of the variable link 23 is tightly fixed to the rear surface (a) of the upper water receptacle of the opening portion 21, As shown in the figure, when the obstacle is inserted into the rear of the watercourse and the watercourse is not conducted, the contact protrusion 24 is detached from the rear surface (a) of the watercourse and the variable link 23 is rotated, It is possible to prevent damage to the cylinder portion 10 even if the piston rod 12 is completely drawn.

In this way, even when an obstacle is placed under the water gate at the time of descending the water gate (2), the pressure of the cylinder is not transmitted to the water gate (2), so damage to the water gate is prevented. .

5, the variable links 23 are disposed on both sides of the piston rod 13 as a pair, and further include a reinforcing rib 25 connecting the inner circumferential surfaces of the contact protrusions 24 So as to prevent warpage.

It is preferable that the contact protrusions 24 are formed so that the width of the contact protrusions 24 gradually decreases toward the ends so that the inner protrusions 24 are in close contact with the back surface of the water receptacle.

That is, the cylinder part 10 supports the water gate 2 when the water gate 2 is raised or turned. At this time, a load applied to the cylinder 12 and the piston rod 13 is transmitted to the fixed shaft 22, The inner edge of the contact protrusion 24 formed on the variable link 23 supports the rear surface a of the water gate 2 so that the load can be efficiently dispersed.

When the cylinder part 10 supports the water gate 2, a plurality of the cylinder parts 10 are provided to support the rear surface of the water gate 2, and if necessary, the cylinder part 10 and the cylinder part 10, The distance between the side walls 10 is reduced to provide a close contact with each other, so that the load of the river can be supported even if the thickness of the gate 2 is significantly reduced, thereby reducing the cost of installing the gate.

The apparatus may further include a rotating shaft fixed to at least both sides of the water inlet, a movable link coupled to an end of the rotating shaft, and a second cylinder and a second piston rod for rotating .

In other words, the second cylinder and the second piston rod are further provided inside the housing disposed on both sides of the water gate in addition to the cylinder portion disposed behind the water gate 2 for rotating the water gate 2, . ≪ / RTI >

As shown in FIG. 9, the water gates 2 can be extended integrally in correspondence with the width of the river, and the water gates can be continuously installed. By the cylinder portion 10 and the variable link portion 20 And can be configured to be individually conducted or standing.
