Vision-based boiler four-tube intelligent detection device

Abstract

The invention belongs to the technical field of boiler detection, and particularly relates to a vision-based boiler four-tube intelligent detection device which comprises a lower platform, two vertical connecting rods are arranged on the lower platform, an upper platform parallel to the lower platform is arranged at the upper ends of the connecting rods, and a control device and a telescopic unit are arranged on the upper platform; the telescopic unit comprises a telescopic rod, a tripod, a winding wheel and a steel wire, the telescopic rod and the tripod are fixed to the upper platform, the telescopic rod is transversely arranged and parallel to the ground, the tripod is provided with the winding wheel, the steel wire is connected between the top end of the telescopic rod and the winding wheel, and the telescopic rod, the tripod and the steel wire are of a triangular structure. One end of the telescopic rod extending out of the upper platform fixes a pan-tilt camera; the control device is connected with the pan-tilt camera through a connecting line. According to the invention, macroscopic scanning of the pipe wall surfaces of the four pipes of the boiler is realized through the boiler hearth inlet hole or the fire observation hole in an insertion manner, so that the difficulties of high labor cost, low working efficiency and the like in the anti-abrasion and anti-explosion work of the four pipes of the boiler are overcome.

Description

technical field [0001] The invention belongs to the technical field of boiler detection, and in particular relates to a vision-based intelligent four-tube boiler detection device. Background technique [0002] In a thermal power plant, the safe operation of the boiler equipment plays a decisive role in the production and operation of the thermal power plant. As an important part of the boiler, the "four tubes" of the boiler have always been the focus of the safety protection inspection of the thermal power plant. However , The explosion and leakage problem of the "four tubes" of the boiler has always been one of the difficult problems affecting the safe production and operation of thermal power generation enterprises. According to authoritative statistics, explosion and leakage incidents of the four tubes on the heating surface of boilers account for about 50% of unplanned outages of units, and even as high as 65% of the incidents on the heating surface of individual thermal...

Problems solved by technology

This method has high labor costs, low work efficiency, harsh on-site environment, and high degree of danger. There is no effective detection method for the internal state of the furnace under the condition of short-term shutdown, and due to the existence of obstacles such as the flame angle, there are blind spots in the detection.
