Description

풍력을 이용하여 수면을 청소하는 예인전차 장치 {Towing carriage apparatus for cleaning water surface using wind power}{Towing carriage apparatus for cleaning water surface using wind power}

본 발명은 예인전차 장치에 관한 것으로서, 보다 구체적으로는 모형선박을 시험하기 위한 수조에 설치된 예인전차를 이용하여 수면의 부유물을 제거하는 풍력을 이용하여 수면을 청소하는 예인전차 장치에 관한 것이다.The present invention relates to a towing vehicle apparatus, and more particularly, to a towing vehicle apparatus for cleaning the water surface using wind power that removes floating matter from the water surface using a towing vehicle installed in a water tank for testing a model ship.

모형시험 수조에서의 시험은 청정한 담수인 청수를 가정한 것이므로 수면의 부유물들을 제거하여 시험의 오차를 최소화하여야 한다. 대형의 모형시험 수조에서는 수조옹벽의 구조적 변화 및 레일의 틀어짐 등으로 인해 수조수 교체가 불가하므로 담수된 수조수를 잘 정화하고 수면을 청소할 수 있는 장치가 필수적이다. 또한 수면청소는 시험 준비 단계에 수행되므로 최단시간에 이루어져야 원활한 모형시험 진행이 가능하다.The test in the model test tank assumes clean fresh water, so the error of the test should be minimized by removing floating substances on the surface of the water. In a large model test tank, it is impossible to replace the tank water due to structural changes of the tank retaining wall and the distortion of rails, so a device that can purify the fresh water tank and clean the water surface is essential. In addition, since sleep cleaning is performed during the test preparation stage, it is possible to proceed with the model test smoothly when it is done in the shortest time.

종래에는 인력을 이용하여 오일펜스 등을 수조의 길이방향으로 끌어 부유물을 수집한 후 부유식 스키머로 부유물을 수거한다. 그러나 많은 인력 및 시간이 소요되며 인력으로 펜스를 끌 때 안전사고의 위험도 수반된다. 또한 수조의 길이방향 옹벽을 따라 설치된 측면소파기와의 간섭으로 인해 안전사고의 우려는 물론 측면소파기 하부로 부유물이 빠져나가는 등 완벽한 부유물의 수집이 어렵다.In the related art, the float is collected by pulling a boom or the like in the longitudinal direction of the water tank using manpower, and then the floating matter is collected with a floating skimmer. However, it takes a lot of manpower and time, and there is also a risk of safety accidents when pulling the fence by manpower. In addition, due to interference with the side sofa installed along the longitudinal retaining wall of the water tank, it is difficult to collect completely floating objects such as safety accidents as well as floating objects escaping to the bottom of the side sofa.

또 다른 방식으로, 예인전차에 설치된 물분사 장치로 전차를 이동하며 부유물을 수집하여 부유식 스키머로 부유물을 수거한다.In another method, the float is collected by moving the tank with a water jet device installed on the trolley, and the float is collected with a floating skimmer.

이와 관련하여 하기의 한국 공개특허공보 제2011-0115227호와 같은 선행기술문헌이 알려져 있다.In this regard, prior art documents such as the following Korean Patent Publication No. 2011-0115227 are known.

그러나, 물분사 방식의 경우 수면의 부유물을 수집할 때, 물분사 시 수면의 교란으로 인해 부유물이 가라앉았다가 다시 떠오르거나 수집되지 않고 물분사 장치 뒤쪽으로 흐르는 등 완벽한 수집이 어렵다. 또한 물분사를 위해 워터펌프로 수조수를 끌어올려야 하는데 펌프라인이 물에 잠겨있으면 시험데이터에 영향을 미치므로 청소시에만 배관을 내렸다가 올려야 하는 번거로움이 있다.However, in the case of the water jet method, it is difficult to collect the floats on the surface of the water completely, such as when the water is sprayed, the floats sink and rise again due to disturbance of the water surface, or flow to the back of the water jet device without being collected. In addition, the water in the tank must be raised with a water pump for water injection, but if the pump line is submerged in water, the test data is affected, so there is a hassle of lowering and raising the pipe only during cleaning.

결국, 종래의 오일펜스나 물분사 방식으로 많은 인력 및 시간이 소요되고, 완벽한 부유물의 수집에 어려움이 있다.As a result, a lot of manpower and time are required by the conventional boom or water spray method, and there is a difficulty in collecting the perfect floating matter.

The posture sensor 46 is installed in the rotation actuator 37 and the elevator driver 38 to generate data on the driving state of the vane 32 and the elevator platform 33 .

본 발명의 세부 구성에 의하면, 상기 제어기(40)는 수면의 교란 및 부유물의 산포 정도에 대응하여 예인전차(20)의 이동 속도, 송풍기(35)의 풍량 및 풍향을 조절하는 것을 특징으로 한다.According to the detailed configuration of the present invention, the controller 40 adjusts the moving speed of the towing vehicle 20, the air volume and the wind direction of the blower 35 in response to the disturbance of the water surface and the degree of dispersion of the floating matter.

수조(10)의 청소 작업에 있어서, 제어기(40)는 예인전차(20)를 일정한 속도로 이동시키고 송풍기(35)를 가동하면서 카메라(42), 부유감지기(44), 자세감지기(46)의 신호를 실시간으로 입력한다. 카메라(42)와 부유감지기(44)의 데이터에 의하여 수면 교란이 설정 범위를 벗어나거나 부유물의 수중 산포가 설정 범위를 벗어나는 경우 예인전차(20)를 제동하여 감속하고 송풍기(35)의 풍량을 줄이고 베인(32)으로 풍향을 변동한다. 물론 수면 교란과 부유물 산포 정도에 대응하는 제어값은 메모리에 축적되는 학습 정보를 근거로 갱신된다.In the cleaning operation of the water tank 10, the controller 40 moves the towing vehicle 20 at a constant speed and operates the blower 35 while operating the camera 42, the floating sensor 44, and the posture sensor 46. Input the signal in real time. According to the data of the camera 42 and the floating sensor 44, when the surface disturbance is out of the set range or the underwater dispersion of the floating object is out of the set range, the towing vehicle 20 is braked to decelerate, and the air volume of the blower 35 is reduced. The wind direction is changed by the vane (32). Of course, the control value corresponding to the surface disturbance and the degree of dispersion of floating matter is updated based on the learning information accumulated in the memory.

종래의 물분사 장치나 오일펜스처럼 수면의 부유물을 포집하면서 수면의 큰 교란이 없이 수면에 떠있는 부유물의 포집이 가능하다. It is possible to collect floating matter floating on the water surface without major disturbance of the water surface while collecting the floating matter on the water surface like a conventional water jet device or a boom.

수면의 부유물들을 제거함에 청소시간이 단축되어 시험시간의 단축이 가능하고 수면 교란이 적어 시험의 오차를 최소화할 수 있다.The cleaning time is shortened by removing the floating substances on the water surface, so the test time can be shortened and the error of the test can be minimized because there is little disturbance of the water surface.

본 발명은 기재된 실시예에 한정되는 것이 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형할 수 있음이 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.The present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such variations or modifications fall within the scope of the claims of the present invention.
