Description

A stream dam possible to gather sand}

The present invention relates to an underwater beam capable of collecting sand that is pushed by the river water and deposited on the bottom surface of the river under the underwater beam, and can smooth the flow of the river water.

In general, underwater streams are installed in rivers to improve the freshwater capacity, so they can be used as agricultural water for natural disasters such as droughts. It is secured by building a dike on the banks and securing it through water barriers, such as underwater beams, or by building small dams or reservoirs in the sagland. These underwater beams, small dams, reservoirs, etc. when the water level is above a certain level to control the amount of storage by opening and closing the manual or semi-automatic upright gates.

Therefore, in the conventional case, the sediment of the surrounding water must be discharged only when the river water stored by the underwater beam is discharged as described above. Therefore, when the water gate is not opened or closed due to lack of water, the desalination capacity of sand decreases, It is destroyed, and there is a risk that red tide may occur due to the decay of other sediments, which causes a problem of deterioration of the river water quality environment.

In order to solve this problem, it is necessary to continuously remove the sediment, but there is a problem that conventional sediments have to remove sediment by separate manual work when the water gate is not opened due to the lack of a function for removing or discharging it. .

The present invention has been devised to solve the above problems, the sand is one of the sediment that is pushed by the river water and deposited on the sea surface under the underwater beams by moving in one direction using a screw and then constructed by collecting it with a conveyor. It is to provide a river underwater beam that forms a fishing house while having a function as a material.

The present invention to solve the above problems,

A recessed sedimentary space is formed in the longitudinal direction of the underwater beams in the front lower portion of the underwater beams, a conveying screw rotated in the deposition space is installed, and a screen having a through hole of a predetermined size is installed in the upper portion of the deposition space. On one side outside provides a submersible sand collecting can be characterized in that the collecting space is formed by the sand transported by the transfer screw is formed.

Here, in the collecting space, a conveyor device attached to a track in which a plurality of buckets are rotated to discharge the collected sands to the outside may be installed at an angle upwards to make sand collecting easier.

At this time, a protective film is installed on the outside of the conveyor device to protect the mechanical devices such as tracks or buckets.

As described above, the underwater beam according to the present invention has an effect that can be usefully used to remove the sand with the advantage of being able to remove the sand causing a variety of problems due to the accumulation in the underwater beam.

The sand used in this way has no salt compared to the sand taken from the sea, so it can be directly put into the field without any additional processing, thereby preventing the end of the secondary construction.

Hereinafter, with reference to the accompanying drawings will be described a submersible sand collecting according to a preferred embodiment of the present invention.

1 is a perspective view showing an underwater beam according to the present invention, and Figure 2 is a front view showing an underwater beam according to the present invention.

1 and 2, the submersible beam 100 capable of collecting sand according to the present invention includes a deposition space 110 formed in a transverse direction in front of the water gate 101 and installed in the deposition space 110. Transfer screw 111, and the screen 112 is installed on the upper portion of the deposition space (110).

First, the deposition space 110 is a space in which sediments floating down in accordance with the flow of water is stacked, it is formed to a certain depth immediately in front of the water gate (101). At this time, in the deposition space 110, the screen 112 is formed on the upper surface through which a through hole of a constant diameter is formed so that only sand of a predetermined thickness or less passes therethrough.

On the lower surface of the deposition space 110, a transport screw 111 is installed to send the deposited sand to one side. The conveying screw 111 is provided with a hydraulic motor for driving the conveying screw 111 in the machine room 105 provided with a hydraulic motor (not shown) for operating the sluice 101. It may be operated or may be operated by an operation switch.

On the other hand, on one side in communication with the deposition space 110, the collecting space 120 is collected and transported as a pool is formed like a puddle.

The collection space 120 is installed with a conveyor device 130 for pulling the transported sand to the outside.

Conveyor device 130 is that one side is located in the collecting space 120 side and the other side is installed obliquely upward, basically the first roller 131 on the opposite side of the collecting space 120, the second roller 132 is opposite And a track 133, such as a belt or chain, which is wound around the rollers 131 and 132 and rotates indefinitely, and a bucket 135 attached to the track 133. Of course, a drive motor (not shown) for rotating the first roller 131 or the second roller 132 is an essential component. In addition, a plurality of connecting rollers 134 may be further provided between the first roller 131 and the second roller 132 to smoothly rotate the track 133.

The conveyor device 130 configured as described above is driven so that the track 133 is rotated from the lower side to the upper side, and the bucket 135 on the lower side pours sand from the collecting space 120, and then rotates on the track 133 and then the track ( 133) is repeated when falling from the opposite side to the bottom.

At this time, the conveyor device 130 may be used to install a protective film 140 to protect the internal device.

On the other hand, the motor for the rotation of the feed screw 111 and the track 133 may also be used as the power generated by the aberration 150. That is, the aberration 150 is installed at any one of the water gates 101, and the first roller of the conveying screw 111 or the conveyor apparatus 130 is driven by the power generated by the generator by driving the generator by the rotational force of the aberration 150. 131 or the second roller 132 may be operated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims. .
