With reference to the drawings, an apparatus and method for removing foreign matter from the bottom of a land waterway according to an embodiment of the present invention will be described in detail.

Figure 1 is a configuration diagram of a foreign matter removal device 100 from the bottom of a land waterway according to an embodiment of the present invention, and Figure 2 is a diagram of the sand pump 120 of the foreign matter removal device 100 from the bottom of a land waterway according to an embodiment of the present invention. It is a cross-sectional view, and FIG. 3 is a bottom view of the blade 123 of the sand pump 120 of the land waterway lower foreign matter removal device 100 according to an embodiment of the present invention.

Referring to FIG. 1, the apparatus 100 for removing foreign matter from the bottom of a land waterway according to an embodiment of the present invention includes a hoist 110, a sand pump 120, a sensor 130, a panel 140, and a controller 150. do.

The hoist 110 is installed on a waterway by, for example, a crane, and can move back and forth, left and right, and go up and down by the controller 150. However, since the hoist 110 itself is substantially the same as a known one or can be easily derived by a person skilled in the art, a detailed description thereof will be omitted.

The sand pump 120 is connected to the hoist 110 and can move forward, backward, left, and right together with the hoist 110, and can be raised up and down. This sand pump 120 descends to the lower part of the waterway and is operated by the controller 150 to suction and remove foreign substances (mud, sand, etc.) in the lower part of the waterway.

More specifically, referring to FIGS. 2 and 3, the sand pump 120 includes a housing 121, an impeller 122, a blade 123, a cover 124, a motor 125, and a shaft 126. do.

The housing 121 has a space inside, and an intake port 121A is formed on the lower surface and a discharge port 121B is formed on the other surface. Therefore, foreign substances can be sucked in through the suction port 121A and discharged through the discharge port 121B.

The impeller 122 is disposed inside the housing 121 and serves to force the flow from the suction port 121A to the discharge port 121B. This impeller 122 may be formed in various types, such as a propeller, paddle, or turbine, as needed.

The blade 123 is disposed adjacent to the suction port 121A of the housing 121 and serves to crush foreign substances entering the suction port 121A. Therefore, by crushing hard or bulky foreign substances such as crustaceans such as barnacles using the blade 123, not only can foreign substances be removed more effectively, but also preventing the inlet 121A or outlet 121B from being blocked by foreign substances. It can be prevented. In the drawing, it is illustrated that three blades are formed and arranged equiangularly, but as long as the blade 123 can properly crush foreign substances, its shape can be changed as appropriate.

The cover 124 surrounds and protects the blade 123 and serves to guide foreign substances entering the intake port 121A of the housing 121 through the blade 123. This cover 124 may be formed integrally with the housing 121 or may be formed separately and attached to the housing 121. In the drawing, the former case is illustrated.

The above-described impeller 122 and blade 123 may be driven simultaneously by a single driving unit or may be individually driven by individual driving units. In the drawing, the former case is illustrated. In this case, the motor 125 is arranged coaxially with the impeller 122 and the blades 123, so that the shaft 126 connects them together.

Referring again to FIG. 1, the sensor 130 serves to detect the amount of foreign matter discharged from the sand pump 120. Since the method or type is not particularly limited as long as the sensor 130 can properly perform its role, specific details regarding this will be omitted. However, to give an example purely for convenience of understanding, the sensor 130 may be a turbidity sensor. Therefore, if the turbidity in the water discharged from the sand pump 120 is measured to be relatively high, it can be determined that the foreign matter is still present in the lower part of the waterway, and if the turbidity is measured to be relatively low, it can be determined that a significant portion of the foreign matter has been removed. .

The panel 140 is installed on land and displays the current location of the hoist 110, the operating state of the sand pump 120, and the measured values of the sensor 130 to the operator. Therefore, the operator can easily check the current position of the hoist 110, the operating state of the sand pump 120, and the measured value of the sensor 130 using the panel 140. Here, the front, rear, left and right positions of the hoist 110 may correspond to the position of the foreign matter, and the up and down positions of the hoist 110 may correspond to the depth of the waterway.

Meanwhile, the current location of the hoist 110, the operating state of the sand pump 120, the measured values of the sensor 130, etc. may be recorded in real time and stored in a database. This information is used to determine and predict how much foreign matter accumulates at a certain point during a specific period, and can be used to plan and operate foreign matter removal work in the future.

The controller 150 is installed on land, and the operator can remotely control the position of the hoist 110 and the operation of the sand pump 120 using the controller 150.

Figure 4 is a flowchart of a method for removing foreign matter from the bottom of a land waterway according to an embodiment of the present invention.

Referring to FIG. 4, the method for removing foreign matter from the bottom of a land waterway according to an embodiment of the present invention includes a hoist installation step (S1), a sand pump connection step (S2), a hoist movement step (S3), a sand pump lowering step (S4), It includes a sand pump operating step (S5), a hoist moving step (S6), a sand pump stopping step (S7), and a hoist return step (S8).

First, in the hoist installation step (S1), the hoist 110 is installed on the waterway using, for example, a crane.

Next, in the sand pump connection step (S2), the sand pump 120 is connected to the hoist 110.

Next, in the hoist movement step (S3), the hoist 110 is moved to the point to be worked using the controller 150.

Additionally, in the sand pump lowering step (S4), the sand pump 120 is lowered to the lower part of the waterway using the controller 150.

The hoist moving step (S3) and the sand pump lowering step (S4) are ultimately intended to place the sand pump 120 toward the foreign matter in the lower part of the waterway, and the hoist moving step (S3) must be faster than the sand pump lowering step (S4). It does not have to be performed first, and the hoist movement step (S3) may be performed simultaneously with the sand pump lowering step (S4) or may be performed later than the sand pump lowering step (S4).

Next, in the sand pump operation step (S5), foreign substances can be suctioned and removed by operating the sand pump 120 using the controller 150.

At this time, the operator can determine whether the foreign matter has been sufficiently removed to allow the sluice gate to be installed in the waterway through the amount of foreign matter discharged from the sand pump 120. This can be confirmed visually by the operator or through the measured value of the sensor 130. For example, if the amount of foreign matter discharged from the sand pump 120 is measured to be relatively large (for example, if the measured value of the sensor 130 is greater than a predetermined standard value), it is determined that the foreign matter is still present in the lower part of the waterway. The sand pump 120 is further operated, and if the amount of foreign matter discharged from the sand pump 120 is measured to be relatively small (for example, if the measurement value of the sensor 130 is less than a predetermined standard value), a significant portion of the foreign matter is It can be judged to have been removed.

If it is determined that a significant portion of the foreign matter has been removed, the work of removing the foreign matter can be continued in the hoist movement step (S6) by moving the hoist 110 to a neighboring point using the controller 150 and operating the sand pump 120. there is.

When all foreign matter removal work for the desired area is completed, the sand pump 120 is stopped using the controller 150 in the sand pump stopping step (S7).

Finally, in the hoist return step (S8), the hoist 110 is returned to its home position using the controller 150.

Furthermore, as a subsequent step, the device 100 may be removed and the sluice gate may be placed in the waterway using a crane.

At this time, as mentioned above, foreign matter at the bottom of the waterway has been removed and the bottom has been made flat, so the water gate can be tightly installed in the waterway.

The apparatus 100 and method for removing foreign matter from the bottom of a land waterway described above are only one of the devices and methods for removing foreign matter from the bottom of a land waterway according to various embodiments of the present invention. The technical idea of the present invention is not limited to the above embodiments, and, as stated in the claims, includes all modifications that can be easily made by a person skilled in the art to which the present invention pertains.
