(Prior Art) As shown in Fig. 1, a conventional underwater monitoring device has a combination of an image sensor 1 for use in the air and a lens 2 with a large aperture, and a waterproof glass 4 on the front. It is built into a waterproof case 3 with a waterproof connector 5 and a waterproof cable 6 to maintain watertightness, and a television monitor 7 monitors the object to be worked on. For lighting, an ordinary underwater lamp 8 can be supplied with electricity using a waterproof power cable 9 and a power source 10. As a result, the size of the device increases, and in turbid water, it is difficult to capture an image even when the object is approached, and even when illuminated, it is often difficult to see due to diffuse reflection. Devices using this method are designed for highly transparent environments and cannot be used in turbid water.

The waterproof image detection element 26 is surrounded by a short cylindrical container. In order to fix the waterproof image detection element 26 to the cylindrical center of the turbid water remover 24, a current plate/support plate 25 was used. A water injection pipe 27 is attached to the rear of the turbid water remover 24, and highly transparent purified water 34 is injected through the water injection pipe 27, and the flow is adjusted with a rectifying plate/support plate 25.
The water flows out through the monitoring window 35 to increase the transparency around the work object. Illumination is guided from the illumination lamp 33 through the illumination fiber 32 to the illumination window 36, and is applied to the workpiece through a fluid with increased illumination intensity. The obtained image is guided to a lens 29 through a fiber cable 37, magnified by the lens 29, and then converted into an electrical signal by a television camera 30. The signal is visualized on a television monitor 31, making it possible to monitor the object to be worked on in turbid water even at a remote location.
