Ultra-wide-angle industrial endoscope applied to float glass tin bath

Abstract

The invention belongs to the technical field of float glass, and discloses an ultra-wide-angle industrial endoscope applied to a float glass tin bath, which comprises a protective sleeve with an observation hole at the front end and a peeping mechanism arranged in the protective sleeve, the length of the protective sleeve ranges from 80 cm to 100 cm. The peeping mechanism comprises a rotating assembly and a camera which is assembled at the observation hole in the protective sleeve through the rotating assembly. On the basis of a rotary scanning working mode of a camera, a short endoscope structural form is applied to a float glass tin bath, and meanwhile, the structure of an observation hole of a protective sleeve is optimized, so that the horizontal visual angle phi of the device is larger than or equal to 110 degrees, dead-angle-free and all-around monitoring on two edge rollers can be achieved at the same time, and the monitoring efficiency is improved. The defects that when an existing endoscope and an existing long endoscope are used on a float glass production line, the horizontal view angle range is small, a monitoring blind area is prone to occurring, the swing angle of an edge roller is prone to being interfered, tin ash is prone to being formed, and large heat loss is prone to being caused are effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of float glass, and relates to a high-temperature industrial television, in particular to an ultra-wide-angle industrial endoscope applied to a tin bath of float glass. Background technique [0002] The tin bath is an important forming thermal equipment in the production of float glass. After the molten glass in the melting furnace flows into the tin bath, it is flattened and thinned under the control of multiple pairs of edge pulling machines 2, and then cooled and formed into glass with a specific thickness and width. In actual production, the position of the head 3 of the edge pulling machine and its operation are usually monitored by high-temperature industrial televisions. At present, high-temperature industrial TVs mainly include two forms of external mirror 4 and long endoscope 5, but both have certain defects, as follows: [0003] 1. Exterior mirror 4 (the working end is located outside the breast ...

AI Technical Summary

Problems solved by technology

The defective of this kind external mirror 4 is:

Therefore, the internal temperature of the tin bath frequently changes, and oxygen seeps into the tin bath, and the loose but not cleaned tin ash is easy to fall to the surface of the glass plate to form defects, which seriously affects the molding quality of the glass and results in a loss of output. loss
