Description

River floor underwater scour prevention device for sand scrubbing {RIPRAP FALLING APPARATUS FOR PREVENTING UNDERWATER DIGGING OF RIVER BOTTOM}

The present invention relates to a sand-seat discharging device, and more particularly, to a riverbed underwater scour prevention stone discharging device to be able to drop the scour prevention stone on the river floor in the correct position.

In general, when a natural disaster such as a flood occurs, a place such as a riverbed may cause the bottom of the water to scour (the degree of flat surface) due to the high flow rate, thereby changing the flow rate.

In particular, when the scour occurs in the riverbed, the flow rate of the water is often changed adjacent to the place where the underwater structure is installed, and thus, the flow velocity of the river is changed adjacent to the underwater structure, thereby destroying the environment. There was this.

1 is a view showing a conventional dead stone discharging device, the excavator 20 is located on the barge 10, the dead stone 30 is loaded on one side of the barge 10, the dead stone 30 ) Using the excavator 20 to drop the sandstone 30 in the scoured place of the underwater structure (40). The barge 10 is a flat pants generally used, the barge 10 is a barge formed integrally is used.

The conventional sandstone dumping device carries out the scour operation for the depth of the underwater structure of the underwater structure by transporting the soil by using the flat pants and unloading the soil or sand by using an excavator. Due to the dropping, there is a problem in that it is not possible to drop the sandstone at a desired and precise position, and also the stone is not dropped at the correct position by the algae.

The present invention is to solve the above problems, by using a bellows-type drum hopper that can flow back and forth, left and right by dropping the stone for preventing scrubbing the river so that it can be dropped in the correct position without being disturbed to the water depth The purpose of the present invention is to provide a sand draining device for preventing underwater scour.

The first jabara drum 320 is formed in a cylindrical shape and is formed in a funnel shape in which the inlet is widened so as to be rotatable up and down at the lower end of the sandstone injection hopper 310, and corresponds to the first fastening bolt hole 311 at the upper end side. A second fastening bolt hole 321 is formed and connected to the sandstone injection hopper 310 by the bolt 101, the nut 103, and the washer 105 to move up and down with the bolt 101 as an axis. In addition, the first jabara drum 320 has two third fastening bolt holes 323 corresponding to each other to form a 90 ° difference with the second fastening bolt hole 321 on the side of the lower end, and the third fastening bolt hole ( Two first wire connecting rings 325 corresponding to each other are formed on the side of the lower end of the same line as 323, and are moved up and down by a wire connected thereto.

The second jabara drum 330 is formed in a cylindrical shape is movable to the left and right at the lower end of the first jabara drum 320, is formed in the form of funnel to widen the inlet and outlet to facilitate the discharge of the sand stone 30, the upper end A fourth fastening bolt hole 331 corresponding to the third fastening bolt hole 323 is formed at a side thereof and is connected to the first jabara drum 320 by the bolt 101, the nut 103, and the washer 105. The bolt 101 is moved left and right about the axis. In addition, the second jabara drum 330 has two second wire connecting rings 333 corresponding to each other such that the fourth fastening bolt hole 331 is 90 ° apart from the bottom side.

In addition, the winding unit 400 is the first winding reel 410, the second winding reel 420, the third winding reel 430, the fourth winding reel 440, the first guide roller 450 ), And a second guide roller 460 and a third guide roller 470.

The first winding reel 410 is connected to the first wire connecting ring 325 located in front of the first wire connecting ring 325 of the first jabara drum 320 to move the first jabara drum 320 forward. The first wire 411 is wound.

The second winding reel 420 is connected to the first wire connecting ring 325 located at the rear of the first wire connecting ring 325 of the first jabara drum 320 to move the first jabara drum 320 backward. The second wire 421 is wound.

The third winding reel 430 is connected to the second wire connecting ring 333 located on the right side of the second wire connecting ring 333 of the second jabara drum 330 to move the second jabara drum 330 to the right. The third wire 431 is wound.

The fourth winding reel 440 is connected to the second wire connecting ring 333 located on the left side of the second wire connecting ring 333 of the second jabara drum 330 to move the second jabara drum 330 to the right. Winding the fourth wire 441.

The first guide roller 450 is installed at the center of the barge 10 to guide the first wire 411 and the third wire 431.

The second guide roller 460 is installed at the end of the fastening beam 200 is installed on the same line as the first guide roller 450 to guide the first wire 411 and the third wire 431.

The third guide roller 470 is installed on the side of the barge 10 to guide the second wire 421 and the fourth wire 441. Here, the first to third guide rollers 450 to 470 are structures that can independently guide two wires, respectively.

Hereinafter, with reference to Figures 2 to 4 the operation of the riverbed underwater scour prevention device for river scour in accordance with the present invention in detail as follows.

In the process of dropping the sandstone 30 in the state of mounting the riverbed underwater scour prevention device 100 to the barge 10, the first wire (1) through the first winding reel 410 of the winding unit 400 ( Winding the 411, and unwinding the second wire 421 through the second winding reel 420, the first jabara drum of the bellows drum hopper 300 connected to the first wire 411 and the second wire 421 ( 320 rotates upward with the bolt 101 as the axis.

As a result, since the first jabara drum 320 and the second jabara drum 330 rotate upwards, the angle at which the sandstone 30 introduced from the excavator 20 to the sandstone injection hopper 310 is dropped is varied. The dead stone 30 is combed and dropped by the refracted angle.

On the contrary, when the second wire 421 is wound through the second winding reel 420 of the winding unit 400, and the first wire 411 is loosened through the first winding reel 410, the first wire 411 is wound. And a first jabara drum 320 of the bellows drum hopper 300 connected to the second wire 421 rotates downward with the bolt 101 as the axis.

Thus, since the first jabara drum 320 and the second jabara drum 330 rotates downward, the angle at which the dead stone 30 is dropped is changed so that the dead stone 30 is combed by the deflected angle.

Further, when the third wire 431 is wound through the third winding reel 430 of the winding part 400, and the fourth wire 441 is loosened through the fourth winding reel 440, the third wire 431 and The second jabara drum 330 of the bellows-type drum hopper 300 connected to the fourth wire 441 rotates upward with the bolt 101 as the axis.

For this reason, since the second jabara drum 330 is rotated in the upper right direction, the angle at which the dead stone 30 is dropped is changed, and the dead stone 30 is combed and dropped by the deflected angle.

On the contrary, when the fourth wire 441 is wound through the fourth winding reel 440 of the winding unit 400, and the third wire 431 is released through the third winding reel 430, the third wire 431 is wound. And a second jabara drum 330 of the bellows-type drum hopper 300 connected to the fourth wire 441 rotates upward with the bolt 101 as the axis.

For this reason, since the second jabara drum 330 is rotated in the upper left direction, the angle at which the dead stone 30 is dropped is changed, and the dead stone 30 is combed and dropped by the deflected angle.

On the other hand, by controlling the first to fourth winding reel (410 ~ 440) of the winding unit 400 at the same time by varying the angle of the first jabara drum 320 and the second jabara drum 330, the desired location of the sandstone 30 It can also be administered accurately.

According to the riverbed underwater scour prevention stone dropping device according to the present invention configured as described above, by dropping the stone for preventing scrubbing using the bellows-type drum hopper that can flow back and forth, left and right, the position of the sandstone is not disturbed to the low water depth There is an advantage to dropping on.
