Description

Technical Field

[0001] This utility model relates to the field of building facility testing, and more specifically, to a fire safety testing device for building electrical facilities. Background Technology

[0002] Building electrical facilities refer to all systems, equipment, lines, and accessories within a building used for receiving, distributing, converting, controlling, and using electrical energy, as well as providing information transmission, security, and emergency power. The fire protection system within building electrical facilities is a complex and crucial safety system built upon an automatic fire alarm system as its core, a reliable and dedicated fire power supply system as its foundation, intelligent and efficient emergency lighting and evacuation guidance systems as lifelines, and stringent fire resistance protection for wiring and grounding lightning protection measures.

[0003] Fire safety inspection of building electrical facilities is a core means of ensuring that the fire protection system is always in an effective state of readiness. Professional inspection and evaluation are conducted to assess the reliability, linkage accuracy, and emergency function integrity of the electrical fire protection system.

[0004] Existing fire electrical facility safety testing instruments require the installation of a universal bracket when entering narrow or irregular spaces within building electrical facilities. This is exemplified by the "angle adjustment of the testing instrument body using a universal bracket" technique disclosed in patent application number 202421645902.6. However, when placed in a vibrating environment (such as a fan room or pump room), the universal bracket's adjustment of the instrument body's angle alters its center of gravity, easily causing it to tip over. In other words, it cannot automatically adjust its posture according to the testing environment to provide stability for the testing. Utility Model Content

The positioning frame includes a positioning frame main body and multiple positioning legs. One end of the positioning frame main body is detachably mounted to the main body of the testing instrument and supports the main body of the testing instrument for fire safety testing of building electrical facilities.

It should be noted that: the main body 100 of the detector is existing technology, and its detailed structure can be found in existing literature and journals, and it can also be purchased directly on the market; it is not what this invention is meant to protect, and will not be described in detail here. Therefore, when it is necessary to enter some narrow or irregular spaces of building electrical facilities, the detector body 100 and positioning frame 200 are driven into the space by the universal bracket. The positioning frame 200 is detachably installed with the detector body 100 using the positioning frame body 300, and supports the detector body 100 for fire safety testing of building electrical facilities. Positioning outrigger 400 includes: A support beam 410 is installed on the positioning frame body 300; the support beam 410 is distributed parallel to the main body of the positioning frame 300. Multiple unit positioning heads 420 are all installed on the support beam 410; the multiple unit positioning heads 420 are distributed at equal intervals along the support beam 410; Therefore, multiple unit positioning heads 420 on one or more positioning legs 400, using the support beam 410 as a support point, are adjusted outward at multiple angles and supported inside the building electrical facilities. This allows multiple positioning legs 400 to lock the detector body 100 in some narrow or irregular spaces within the building electrical facilities through their multiple unit positioning heads 420 (see details for reference). Figure 8 The demonstration of the positioning leg 400 adapting to the detection environment and adjusting the rotation angle of the positioning head 420 can automatically adjust its posture according to the detection environment in order to provide detection stability for the main body 100 of the detector.
