  Hereinafter, in order to make it easier for those skilled in the art to understand the contents of the present invention and to clarify the objects, features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  In the following description and claims, the term “connection” should be broadly understood unless the context clearly dictates otherwise, eg, mechanical connection, electrical connection, or two It may mean communication inside the part, or may mean direct connection or indirect connection via an intermediate medium. A person skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

  FIG. 1 is a block diagram showing an aquatic sediment removal apparatus according to an embodiment of the present invention. As shown in FIG. 1, the water body sediment removing apparatus according to the present embodiment includes an imaging collection device 100, a high-pressure pump 110, a controller 120, a sand injection device 130, a mixer 140, a nozzle switching structure 150, The nozzle 160 may be included.

  In this embodiment, when removing an aquatic sediment, an operator first pushes a removal start button after preparing an aquatic sediment removal apparatus. At this time, the imaging collection device 100 collects video information at the position of the protruding nozzle 160 and transmits it to the controller 120. The controller 120 compares the video information with the preset shape characteristics of each type of water sediment, and if this video information matches the preset shape characteristics of a certain type of water sediment, a protruding nozzle The aquatic sediment at the 160 locations is determined as this kind of aquatic sediment. Since the person skilled in the art can realize the comparison and identification processing between the video information and the preset image by the conventional technique, the details thereof are omitted.

  After determining the type of the water body deposit at the position where the protruding nozzle 160 is located, the controller 120 transmits a water pressure adjustment signal to the high-pressure pump 110 according to the type, and transmits a sand injection adjustment signal to the sand injection device 130. At the same time, a switching signal can be transmitted to the nozzle switching structure 150. After receiving the water pressure adjustment signal, the high-pressure pump 110 can adjust the pressure of the discharged water based on the water pressure adjustment signal. After receiving the sand injection adjustment signal, the sand injection device 130 can adjust the amount of sand injection to be injected based on the sand injection adjustment signal. After adjusting the water pressure and the sand injection amount, the water discharged from the high-pressure pump 110 and the sand injected from the sand injection device 130 are mixed in the mixer 140 and output to the nozzle 160. In this way, the nozzle 160 cuts and removes the water deposits based on the adjusted water pressure and sand injection amount.

  Further, after receiving the switching signal, the nozzle switching structure 150 switches the type of the nozzle 160 based on the switching signal. FIG. 2 is a diagram illustrating the configuration of the nozzle switching structure 150. As shown in FIG. 2, the nozzle switching structure includes a transmission mechanism 151, an elastic mechanism 152, and an elevating mechanism 153. Each nozzle 160 is fixed to a corresponding position of the transmission mechanism 151 via the elastic mechanism 152. A through hole communicating with the mixer 140 is installed at a position of the transmission mechanism 151 that faces the fixed position of each nozzle 160. By doing so, it is possible to communicate with the mixer 140 even after the nozzle 160 corresponding to the transmission reaches the preset protruding position. In addition, an elevating mechanism 153 is installed below the preset protruding position. A suction cup 154 is installed at the top end of the lifting mechanism 153. The transmission mechanism 151 may include a transmission belt and a drive motor that drives the transmission belt. The elastic mechanism 152 may be a spring or rubber. The lifting mechanism 153 may be a hydraulic lift.

  In order to ensure that the nozzles that are switched during nozzle switching always communicate with the mixer, the separation distances of the transmission mechanisms of the nozzles are made the same, and the nozzles are positioned on the same plane during the transmission. In the process of removing water deposits using a nozzle, in order to ensure that other nozzles do not affect the necessary nozzle removal work, a protective case is added outside the nozzle switching structure 150. Also good. The operating principles of the transmission mechanism, the lifting mechanism and the suction cup are the same as in the prior art, and the details thereof are omitted. In the present invention, by installing a suction cup at the top of the lifting mechanism, it is possible to avoid the movement of the nozzle during cutting, and as a result, it is possible to improve the cutting accuracy. FIG. 3 is a view in the direction of arrow A in FIG. In FIG. 3, the main body of the nozzle 160 is indicated by 171, and the input port of the nozzle 160 is indicated by 172. Further, the suction cup 154 adsorbs to the main body 171 of the nozzle 160 without contacting the input port 172 of the nozzle 160. Thereby, the communication between the input port of the nozzle and the mixer can be ensured.

  During the switching of the nozzle switching structure 150, first, the controller 120 controls the transmission mechanism 151 to transmit power having a preset distance, thereby moving the necessary nozzle 160 to a predetermined protruding position. Next, the controller 120 causes the nozzle 160 to protrude from the case of the nozzle switching structure 150 by raising the lifting mechanism 153 and adsorbing the suction cup 154 to the nozzle 160. When it is necessary to switch to the next type of nozzle 160, the controller 120 first lowers the lifting mechanism 153 and does not suck the suction cup 154 to the nozzle 160. At this time, the nozzle 160 is returned by the elastic mechanism 152. Next, the controller 120 moves the nozzle 160 of the next type to a preset protruding position by controlling the transmission mechanism 151 so as to transmit power having a preset distance, and also moves the lifting mechanism 153. By raising, the next type of nozzle 160 is projected from the case of the nozzle switching structure 150. In this way, nozzle switching is repeatedly executed. In addition, the cutting principle of the said water body sediment removal apparatus is the same as the cutting principle of a water jet cutting apparatus.

  According to the above embodiment, the present invention can increase the cutting efficiency of the water sediment by controlling the high-pressure pump so as to adjust the cutting water pressure of the water sediment according to the type of the water sediment. Waste of energy due to cutting can be eliminated. In addition, the present invention can further improve the cutting efficiency of the water deposits by controlling the sand injection device so as to adjust the sand injection amount according to the type of the water deposits, and can also reduce the energy by cutting.
