Description

[Detailed description of the invention] This invention is an ice floating system that takes in water containing floating matter to the optimal depth below the water surface, and continuously separates and collects the upper layer of floating matter, and collects it by suction. The present invention relates to a water intake device for a water floating object recovery device used in a recovery device.

Floating substances such as spilled oil, industrial waste fluids, and harmful microorganisms in water bodies such as oceans, ports, lakes, and rivers cause various forms of pollution, such as environmental destruction, deterioration of water quality, and loss of marine resources.

In recent years, the frequency of occurrence of pollution in water bodies has increased rapidly.
Most of the cases are caused by various floating substances.

However, technology for removing floating objects in water bodies has not yet been established, and it is not only possible to prevent the pollution of water areas by various types of floating objects, but also to remove floating objects that have already occurred in water areas quickly, safely and reliably. Establishing a technology for recovery is an urgent issue these days.

Therefore, the present invention aims to quickly and efficiently recover floating matter such as spilled oil, industrial waste liquid, or harmful microorganisms, regardless of the environmental and weather conditions of the water area in which these floating matter are floating. The main object of the present invention is to obtain a water intake device for a water floating object recovery device that can be used in a water floating object recovery device.

The bottom wall 47, the top wall 53, and the left and right side portions 52, 52' cooperate with each other to constitute a floating matter suction pipe A.

The floating matter suction pipe A is wide and thin at the front end opening, and gradually narrows toward the rear end so that the flow rate of floating matter passing through the floating matter suction pipe A is kept as constant as possible. It is desirable that the thickness be increased.

A rear end portion 57 of the suspended matter suction pipe A is formed in a circular tube shape, and communicates with the suction side of a pump 59 disposed on the main body 3 via a flexible tube 58.

The floating matter sucked by the pump 59 is pumped through the transfer pipe 60, the swivel joint, and the transfer hose joint 61 to the floating matter recovery tank.

In the floating matter suction device 46 , the pair of left and right buoyancy adjustment floats 51 , 51 ′ always maintain the floating matter suction depth at the front edge of the bottom wall 47 at a selectively set constant depth, and the backflow prevention wall 48 .54 prevents the floating matter once sucked into the floating matter suction pipe A from flowing back due to the shock wave.

The suspended matter suction pipe A operates in a downwardly inclined position from the front edge to the rear edge.

By operating the floating matter suction pipe A in such a posture inclined rearward and downward, floating matter suction operation is performed efficiently.
