Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0024] Such as figure 1 As shown, a test platform for the fire characteristics of an electrical shaft includes a shaft 1. In actual buildings, the electrical shaft is mostly a cubic structure built along the building wall. With the same cubic structure, those skilled in the art can also design the shaft 1 as other similar structures as required, and thus make adaptive modifications to other specific structures. by figure 1 In the direction shown, a transparent observation door (not shown) that can be opened flexibly is provided on the front of the shaft 1, so as to adjust the structural layout inside the shaft 1 and replace parts; A video capture device (not shown), the video capture device is preferably a video camera....

The invention discloses an electric vertical shaft fire disaster characteristic test platform. The test platform comprises a vertical shaft which has a cylinder structure, the vertical shaft is internally provided with a strong electric bridge frame and a weak electric bridge frame, which are closed, along the vertical direction, and the strong electric bridge frame and the weak electric bridge frame are internally provided with a strong electricity cable and a weak electricity cable; the bottom of the vertical shaft is provided with a heat source for heating the strong electricity cable and / or the weak electricity cable; in the vertical shaft, a temperature sensor and a smoke detector are arranged at different heights. The electric vertical shaft fire disaster characteristic test platformprovided by the invention has the advantages that the fire disaster propagation process can be restored through multiple angles via the analyses of temperature, gas components and concentration as well as images, the platform can be used for respectively evaluating factors such as cable variety, fire barrier variety and configuration mode, cable bridge frame variety as well as strong and weak cable laying intervals, so that a relatively scientific electric vertical shaft fire prevention scheme is obtained through tests, and the test platform has a good application prospect.
Description
technical field [0001] The invention relates to the technical field of electrical shafts, in particular to an electrical shaft fire characteristic testing platform. Background technique [0002] Electrical shaft wiring is the main laying method for vertical power distribution trunk lines in multi-storey and high-rise buildings. In actual engineering, regular power lines and non-power lines coexist in the same electrical shaft, and electrical wiring for high-voltage, low-voltage and emergency power supplies in power line cables Lines and cables are often arranged in a centralized manner, and they are in a state of running heat all year round. Poor ventilation and aging contacts may cause fire accidents. When a fire occurs in an electrical shaft, a chimney effect is easily generated, and the fire spreads rapidly, and a large amount of high-temperature toxic smoke is seriously affected by the safe evacuation of personnel. It is difficult to fight the fire, and once a fire occur...
