Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 , figure 2 As shown, a performance detection device for road tunnel linear fire detectors is provided with a heating box 1 for realizing temperature changes. As the best implementation mode, the upper end surface of the heating box 1 is rectangular and the upper end is open. Four temperature sensors 2 are installed on the peripheral edge of the upper opening, and at least one electric heating rod or heating wire 14 is installed horizontally in the box body of the heating box 1, image 3 What adopted in is 2 heating wires, and the installation position of this heating wire 14 is close to the upper end opening of described heating box 1. Since the fire detector is linear, the opening at the upper end of the heating box 1 is set as a rectangle, so that the heating wire 14 is arranged horizontally, and the heat ...

Abstract

The invention discloses a device for detecting the performance of a highway tunnel line-type fire detector. The device is characterized in that: a heating box for realizing temperature change is arranged; the upper end of the heating box is open; at least one temperature sensor is arranged on the peripheral edge of the opening at the upper end; the lower end of the heating box is fixed to an output shaft of a first rotating device; the first rotating device is arranged at one end of a support arm; the other end of the support arm is arranged on an automatic lifting platform through a second rotating device; the automatic lifting platform is fixed on a moving trolley which is provided with an operating platform; and the operating platform is provided with a first rotating shaft control device, a second rotating shaft control device, a lifting platform control device, a temperature adjusting device and a display device. The device has the remarkable advantages that: ignition is not required, the pollution is light, traffic is not required to be closed, social influence is a little, personnel is not required to operate the device overhead, personnel safety is ensured, the system structure is simple, the cost is low, and the mobility and reliability are high.

Description

technical field [0001] The invention relates to a performance detection device for fire-fighting equipment, in particular to a performance detection device for linear fire detectors in highway tunnels, which is mainly used for performance detection of linear fire detectors in large tunnels. Background technique [0002] With the increasing improvement of road traffic, the distribution of tunnels is becoming more and more dense, especially for large tunnels, due to the closed space, once a fire breaks out, it is very difficult to fight fires and easily cause heavy casualties. Therefore, the fire safety of tunnels is very important, and how to discover tunnel fire hazards early and in time has become a subject of concern. In view of the above reasons, it is clearly required in road regulations that fire detectors must be installed in large tunnels. The existing fire detectors are divided into point type and linear type. The point type fire detectors commonly used in highway t...
