Waterproof paint film thickness measuring device for use on underwater unmanned vehicles

Abstract

This invention provides a waterproof paint film thickness measuring device for use on underwater unmanned vehicles. It mainly includes a housing body, a carrier plate assembly, a measuring host, an upper cover, a lower cover, signal terminals, and a detection unit. The carrier plate assembly is located in the hollow space of the housing body and abuts against the inner wall surface through the outer periphery of the upper and lower ring plates, so that the measuring host is firmly fixed to the carrier plate. The upper and lower covers seal the housing body to achieve waterproofing. The probe of the detection unit is located on the outside and is connected to the internal measuring host through an electrical connection wire passing through the upper cover. It is used to detect the paint thickness on the surface of wind turbine foundation piles or ship hulls. This invention has a stable structure and high environmental adaptability, and can be mounted on unmanned vehicles to perform automated underwater paint inspection.

Claims

1. A waterproof paint film thickness measuring device for use on an underwater unmanned vehicle, mounted on an underwater unmanned vehicle, comprising: a housing body having a hollow housing space; a carrier plate assembly disposed within the housing space, the carrier plate assembly comprising a carrier plate, an upper annular plate disposed on the top of the carrier plate, and a lower annular plate disposed on the bottom of the carrier plate, wherein the outer peripheries of the upper and lower annular plates abut against the inner wall of the housing space, thereby stably supporting the carrier plate within the housing body; and a measuring main unit, which is detachable. The device is fixed to the carrier plate in a certain way; an upper cover and a lower cover are respectively sealed to the top and bottom of the accommodating body to form a waterproof and sealed state of the accommodating space; at least one signal terminal is disposed on the upper cover and electrically connected to the measuring host for outputting measurement data; and at least one detection unit includes a probe and an electrical connection wire, the electrical connection wire passes through the upper cover and is electrically connected to the measuring host, the probe is located outside the accommodating body and is used to detect the paint surface condition of a test object.

2. The waterproof paint film thickness measuring device as described in claim 1, wherein the signal terminal transmits the data of the measuring host to the underwater unmanned vehicle or a remote receiver via wired or wireless transmission.

3. The waterproof paint film thickness measuring device as described in claim 1, wherein the detection unit is provided with multiple arrays, and the top cover is provided with multiple waterproof openings for the electrical connection wires to pass through.

4. The waterproof paint film thickness measuring device as described in claim 1, wherein the housing is a semi-closed shell with an open bottom, and the lower cover is omitted, so that the hollow housing space forms an opening at the bottom.
