The backflow prevention door 1050 has a certain weight and is rotatably provided on the loss prevention body 1010 to open and close the loss prevention discharge unit 1040, and is opened and discharged by the pressure of the seawater and sand discharged.

When the discharge pressure is lower than the weight of the backflow prevention door 1050, the loss prevention discharge part 1040 is closed to prevent backflow of seawater and sand.

According to such a sand loss prevention device 1000, seawater and sand flowing to the shore are introduced into the loss prevention inlet 1030 to rotate the loss prevention rotating part 1020 and at the same time open the backflow prevention door 1050 to the shore. The seawater that is discharged and swept away is moved to the upper side of the loss prevention body 1010, but the sand is prevented from moving by the closed backflow prevention door 1050 and accumulates on the shore.

Accordingly, it is possible to prevent the sand on the shore from being lost.

For this, the loss prevention rotation unit 1020 includes a loss prevention rotation shaft 1022 and a rotation blade 1024 as shown in FIG. 10.

The loss prevention rotation shaft 1022 is rotatably provided in the rotation space portion 1012.

In other words, the facing surface is formed concave so as to receive rotational force by the pushed seawater, and is formed convex to the rear side.

Accordingly, it is easily rotated by receiving rotational force by the pushed seawater, so that seawater and sand can be supplied to the loss prevention discharge unit 1040 and discharged to the shore.

And the loss prevention rotation unit 1020 further includes an elastic guide (1026).

The elastic guide 1026 has elasticity, and is provided at the end of each rotary blade 1024 and rotates together, thereby scraping the inner surface of the rotating space portion 1012.

Here, the elastic guide 1026 is bent and rotated in a direction opposite to rotation when scraping the inner surface of the rotating space part 1012, and seawater and sand It is moved to the loss prevention discharge unit (1040).

Of course, seawater and sand are moved to the loss prevention discharge unit 1040 by the centrifugal force of the loss prevention rotation unit 1020, but can be moved more easily by the momentary elastic force of the elastic guide 1026, so that the rotating space unit ( 1012) can minimize the remaining sand.

And as shown in FIG. 11, the sand loss prevention apparatus 1000 further includes a second loss prevention unit 1060.

The second loss prevention part 1060 allows some of the washed off seawater to move through the rotation space part 1012 to rotate the loss prevention rotation part 1020, thereby removing the sand remaining in the rotation space part 1012. It is induced to discharge to the loss prevention discharge unit 1040.

The second loss prevention part 1060 includes a second loss prevention inlet 1062, a second loss prevention discharge part 1064, and a second backflow prevention door 1066.

The second loss prevention inlet 1062 is provided at the rear end of the loss prevention body 1010 so that a part of the washed off seawater flows into the upper end of the rotational space 1012 after passing through the loss prevention discharge 1040.

And the second loss prevention discharge unit 1064 is a loss prevention body 1010 so as to discharge seawater by rotating the loss prevention rotation unit 1020 through the second loss prevention inlet 1060 to the front side of the loss prevention body 1010. ) Is provided at the top of the front.

The second backflow prevention door 1066 has a certain weight and is rotatably provided on the loss prevention body 1010 to open and close the second loss prevention discharge part 1064.

The second backflow prevention door 1066 is opened and discharged by the pressure of the seawater discharged, and when the discharge pressure is lower than the weight of the second backflow prevention door 1066, the second loss prevention discharge part 1064 is closed. To prevent seawater from entering

Looking at the operating state of the second loss prevention unit 1060, some of the washed off seawater flows into the second loss prevention inlet 1062 to rotate the loss prevention rotation unit 1020 and at the same time, the second reverse flow prevention door ( 1066) is opened and discharged.

In other words, as the loss prevention rotation unit 1020 is rotated by the seawater swept away through the second loss prevention unit 1060, the sand remaining in the rotation space unit 1012 is rotated to the lower end of the rotation space unit 1012. The sand that prevents the rotation of the loss prevention rotating part 1020 is removed by preventing it from accumulating in the.

Accordingly, the loss prevention rotation unit 1020 may be maintained in a rotatable state by the pushed seawater.

In addition, the sand loss prevention device 1000 further includes a loss prevention and supply unit 1070 as shown in FIG. 12.

The loss prevention oversupply unit 1070 is provided to increase the discharge rate as some of the pushed seawater is introduced and oversupplied to the loss prevention discharge unit 1040.

The loss prevention oversupply unit 1070 includes an oversupply inlet 1072, an oversupply supply hole 1074, an oversupply path 1076, and an oversupply cover 1078.

The oversupply inlet 1072 is formed at the upper end of the front end of the loss-preventing body 1010 in order to inflow seawater.

And the oversupply supply hole 1074 is formed inside the rear end of the loss prevention body 1010 to supply the introduced seawater from the side direction of the loss prevention discharge unit 1040.

The oversupply path 1076 is formed in the loss prevention body 1010 to communicate the oversupply inlet 1072 and the oversupply hole 1074.

In addition, the oversupply cover 1078 is provided to open and close the oversupply supply hole 1074.

Looking at the operating state of the loss prevention and supply unit 1070 as described above, when the seawater pushed in passes through the oversupply supply hole 1074 through the oversupply inlet 1072 and the oversupply path 1076, the oversupply cover ( The seawater 1078 is opened and the seawater is oversupplied to the loss prevention discharge unit 1040.

Accordingly, seawater and sand can be discharged closer to the shore by increasing the speed discharged through the loss prevention discharge unit 1040.

Here, the second loss-prevention unit 1060 and the loss-prevention unit supply unit 1070 are provided with any one or more, and may be formed at the same time, and when formed together, it is natural that they are formed to be partitioned from each other.

As such, the coastal erosion prevention method using the sand loss prevention device 1000 includes an installation line setting step (S100), a sand loss prevention device installation step (S110), a sand deposit confirmation step (S120), and an installation line correction step (S130). And a position correction step (S140).

In the installation line setting step (S100), an installation line (L) in which the sand loss prevention device 1000 for preventing sand loss is to be installed is set.

And the sand loss prevention device installation step (S110) installs the sand loss prevention device 1000 along the installation line (L).

In the sand deposit confirmation step (S120), the sand stacking state of the shore is checked by the sand loss prevention device 1000 installed using a satellite image.

It is natural that the sand deposit confirmation step (S120) can be used as long as it is possible to check the stacking and deposit amount as well as satellite images.

In addition, the installation line correction step (S130) resets the installation line (L') of the sand loss prevention device 10 according to the confirmed sand accumulation amount.

The position correction step (S140) moves the position of the corresponding sand loss prevention device 1000 along the corrected installation line L'.

Here, it is natural to repeat the sand deposit confirmation step (S120), the installation line correction step (S130), and the position correction step (S140).

Accordingly, it is possible to prevent the sand from being lost, as well as to prevent the sand from being over-deposited.

And in the sand loss prevention device installation step (S110) and the position correction step (S140), the movement of the sand loss prevention device 1000 is installed using a crane and a wire, and if necessary, an eyebolt to the sand loss prevention device 1000 It is natural that you can install it and hang a hook on the end of the wire.
