Diversion Weir Structure For Ecological River Maintenance Capable Of Easily Filtering Floating Matter From River Water}

The present invention relates to a river bank structure for maintaining an ecological river.

In general, a river wearing a farmland is provided with a structure such as a blow beam to store a certain amount of river water, and is supplied with necessary agricultural water therefrom.

However, when the rain falls a lot like the rainy season, the floats are washed in the rainwater and flow into the river, so a huge amount of time and manpower must be invested in cleaning the river.

And, if the river is too deep for the worker to enter, the net was suspended in both sides of the river to float down the floating float no longer down to remove the work, but the river was to work on both sides was inconvenient, It was inconvenient because it was not easy to collect the suspended matter on the net and collect it by the riverside.

The motor 340 is operation controlled by the controller 700 to be described later.

3 to 6, the ocher discharge mechanism 400 guides the suspended matter (G) filtered to the network structure 200 to the left and right while collecting the loess accommodated therein to the river as a guide 120 to the collection 120 In the present embodiment, the hopper 410 and the guide plate 420 are configured.

The hopper 410 is a well-known mechanism for storing and supplying granules such as loess, and is installed at the front surface of the transfer block 330 in the present embodiment. The hopper 410 is a locus or cone shape having a light-receiving narrow shape as a whole is discharged through the lower loess accommodated therein. In particular, the opening and closing cover 411 is rotatably installed through the hinge in order to limit the discharge of the indiscriminate loess at the lower outlet. In addition, the loess accommodated in the hopper 410 contains a small amount of moisture, so the coagulation force is good, and thus may not easily be discharged even when the opening and closing cover 411 is opened. Therefore, in order to solve the above problems, a plurality of vibrators 600 are installed on the outer surface of the hopper 410, and the loess accommodated therein is easily discharged to the river by vibrating the hopper 410 via the vibrator 600. It could be. For reference, the loess accommodated in the hopper 410 is a function of capturing cyanobacteria that block oxygen so that oxygen in the air can be well dissolved in the stream. In the present embodiment, the loess is described as one embodiment. As long as it can perform the same function, any of the known ones can be applied.

The guide plate 420 is installed in the transfer block 330 serves to guide the floating material (G) filtered by the strainer 210 to be moved to the collection box (120). In particular, the guide plate 420 is formed with a plurality of holes 421, which minimizes the resistance of the water so that it can easily cross the river to minimize the guide plate 420 is bent or damaged by the resistance of the water give. In the present embodiment, the guide plate 420 is illustrated and described in the form of a plate, but this is only one embodiment and may be modified to various known forms as necessary.

Subsequently, the dissolved oxygen detecting sensor 500, the vibrator 600, and the controller 700 will be described with reference to FIG. 7.

The dissolved oxygen sensor 500 is a known mechanism for detecting (measuring) the concentration of dissolved oxygen (DO) in a stream and transferring the detected result value (measurement value) to the controller 700. It is installed between the 110 and the support frame 210. Since the dissolved oxygen sensor 500 is well known in the art, a description of the composition and the method of detecting (measuring) the concentration of dissolved oxygen will be omitted.

The vibrator 600 is a known vibrator, is installed in the hopper 410 is controlled by the control unit 700. Here, the vibrator 600 has a function of applying a vibration so that the loess accommodated in the hopper 410 can be easily discharged.

The controller 700 receives the result value (measurement value) detected from the dissolved oxygen sensor 500 and compares the result with the preset value to the motor 340 when the detected result value (measurement value) is out of the preset value. It functions to control the vibrator 600.

According to the present embodiment, the dissolved oxygen sensor 500 continuously detects (measures) dissolved oxygen (DO) while maintaining contact with water in the stream, and the detected result (measured value) is controlled by the controller 700. The controller 700 compares the detected result value (measured value) received from the dissolved oxygen sensor 500 with a preset value. At this time, when the result (measured value) detected by the dissolved oxygen sensor 500 is out of the preset value of the control unit 700, the control unit 700 operates the motor 340 and the vibrator 600 at the same time. When the motor 340 is driven by the control unit 700, the lead screw 320 is rotated in the forward (reverse) direction, the transfer block 330 threaded to the lead screw 320 is the lead screw 320 It moves along the longitudinal direction, and thus the loess discharge mechanism 400 fixed to the transfer block 330 is moved naturally with the transfer block 330. And, due to the vibration of the vibrator 600 installed in the hopper 410 of the ocher discharge mechanism 400, the ocher is easily discharged to the river through the discharge port. Furthermore, when the hopper 410 is moved, the guide plate 420 installed in the transfer block 330 is also moved together so that the floating material G caught on the network structure 200 moves from side to side to the collection box 120. , The guided float (G) is easily guided through both ends of the support frame 210 inclined toward the collection box 120 is introduced into the collection box 120, so the floating material (G) causing the flow of the river and environmental pollution It can be removed smoothly. For reference, the control unit 700 may drive the motor 340 according to a setting state to reciprocate the transfer block 330 once and stop the operation, but may also be set to stop after several round trips as necessary. have.

Referring to the operation of the present invention made of the configuration as described above are as follows.

Referring to FIG. 5, when the heavy rain falls for a certain period of time, such as during the rainy season, the water level of the river rises more rapidly than usual, thereby flooding the river bank (1) and flooding the nearby tillage and residential areas. Will cause.

As such, when the rain level temporarily increases, the buoyancy member 132b provides buoyancy to the elevating plate 132 according to the level change, and the elevating plate 132 mediates the buoyancy of the buoyancy member 132b. The road is elevated along the guide plate 131 and rises relatively higher than the river bank 1.

Therefore, it is possible to temporarily solve the problem of rivers overflowing the river bank 1 by the elevating plate 132 formed relatively higher than the river bank 1, since the additional levees need not be additionally installed. There is an advantage that can significantly reduce the construction cost.

On the other hand, when the water level of the river is lowered, the lifting plate 132 is naturally lowered.

On the contrary, referring to FIG. 6, after the rainy season, a sweltering dry season lasts. In general, when the dry season is not rainy, the temperature of the stored river rapidly rises when there is no heat wave and stream flow in summer. It multiplies, causing green algae, where the water turns green.

Therefore, this causes the dissolved oxygen (DO) of the stream to be different, such dissolved oxygen (DO) is detected (measured) in real time while maintaining the dissolved oxygen sensor 500 in contact with the water of the stream, The result value (measurement value) is transmitted to the control unit 700, and the control unit 700 compares the detected result value (measurement value) received from the dissolved oxygen detection sensor 500 with a preset value.

In this case, when the resultant value (measured value) detected by the dissolved oxygen sensor 500 is out of a predetermined value of the controller 700, the controller 700 operates the motor 340 and the vibrator 600 simultaneously. .

In more detail, the motor 340 is driven by the controller 700, and the lead screw 320 is rotated in the forward (reverse) direction by the driving of the motor 340. The transfer block 330 threaded to the 320 is moved along the lengthwise direction of the lead screw 320, and thus the ocher discharge mechanism 400 fixed to the transfer block 330 together with the transfer block 330. It moves naturally.

In particular, when the hopper 410 of the ocher discharge mechanism 400 moves, the vibrator 600 is also operated together, and due to the vibration of the vibrator 600, the loess is easily discharged to the river through the opening and closing cover 411. .

In addition, when the hopper 410 is moved, the guide plate 420 installed in the transfer block 330 is also moved together, so that the suspended matter (G) caught on the network structure 200 is moved to the left and right by the guide plate 420. It is led to the inclined both ends of the support frame 210 is naturally collected in the collection box (120).

Therefore, by eliminating the algae phenomenon through the above-described action can be smoothly removed to remove the suspended solids (G) causing the flow of the river and environmental pollution, so that the natural ecological river can be more clean.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
