Problems solved by technology

The common thermocouple support device is generally assembled by angle steel, but the structure of the angle steel support device has the following disadvantages: (1) the assembly height exceeds 3m, it will be unstable and easy to collapse; (2) the position of the thermocouple measuring point is inconvenient to adjust; (3) lack of thermocouple protection device, reduce service life, etc.
These shortcomings make the conventional angle steel thermocouple support unsuitable for use in large space fire experiments

Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings and specific examples.

[0022] A thermocouple support device used in large-space fire experiments, its structure schematic diagram is as follows figure 1 As shown, the device is composed of six parts, including a base part, a horizontal protective sleeve part, a vertical fixed steel pipe part and a metal buckle part.

[0023] Wherein the base part 1 is a square cast iron of 40×40×5 cm, and the supporting part 2 is four pieces of equilateral right triangle cast iron, and the length of the right angle side is 21 cm. Such as figure 1 As shown, the support part 2 is welded on the base part 1. The thick casing part 3 has a diameter of 4cm and a length of 3m, and the lower end is welded together with the base part 1 and the support part 2, such as figure 1 shown. The thin casing part 4 has a diameter of 3 cm and a length of 6 m, and is inserte...

Abstract

The invention provides a thermocouple support apparatus applied to a large-space fire experiment. The thermocouple support apparatus comprises a pedestal portion, a supporting portion, a thick sleeve portion, a thin sleeve portion, a thermocouple hole portion, and a bolt buckle portion. The thermocouple support apparatus is simple in principle and easy to operate, may easily performs adjustment, including rotation and up and down movement, on a thermocouple measuring point position in a large-space fire experiment, has good mechanical stability, has high safety, protects the thermocouple, prolongs the service life of the thermocouple, and facilitates the dismounting of the thermocouple. The thermocouple support apparatus is good in popularization and wide in application range, and can be generalized and used in a large number of large-space fire experiment occasions such as stadium fire experiment temperature measurement, subway fire flue-gas temperature field measurement, tunnel fire flue-gas temperature field measurement, large market fire flue-gas temperature field measurement and the like.

Description

technical field [0001] The invention relates to a thermocouple support device used in large-space fire experiments, especially a support device that can be applied to large-space fire experiments and can conveniently adjust the position of thermocouple measuring points, including rotation and up-and-down movement. With thermocouple protection function. Background technique [0002] With the rapid economic growth, the improvement of people's living standards, the convenience and modernization of social life, the number of large-space buildings such as highway tunnels, subways, and stadiums has also sprung up. The research on fires in such large-space buildings It also becomes more important. Among them, temperature is an important fire research parameter, and thermocouples and thermocouple brackets are generally used for data collection. Thermocouple support devices are widely used in scientific research on combustion, thermal energy, and fire protection, as well as in soci...
