[0003] Fire resistance detectors for mineral cable production usually refer to special equipment used to detect the fire resistance of mineral cables. They are also called mineral cable fire resistance testers or fire resistance characteristics testers. These devices are mainly used to evaluate the fire resistance of mineral cables under extreme conditions such as fire, ensuring that the cables can maintain normal operation under specific conditions, thereby ensuring the safety and reliability of power transmission.

[0004] At present, in actual operation, the detector needs to fix the two ends of the cable respectively, and then clamp the measuring tool on the conductors at both ends of the cable. At present, in fixing the cable, it is necessary to fix one end of the cable first, and then pick up the other end of the cable and fix it to the corresponding position, and then manually straighten the cable, and then perform the fixing operation, which makes the installation operation of the cable during detection more cumbersome, resulting in low detection efficiency.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention, through the arrangement of a moving component and a fixed placement component, first fixes one end of the cable on a fixing ring, then starts a motor to drive a threaded rod to rotate, and then allows an internal threaded sleeve to move on a surface of a motor, thereby driving a fixing ring and one end of the cable to move to an inner cavity of a placement bin, and then the second fixed threaded rod can be twisted to move the arc-shaped clamping block downward, and then the other end of the cable can be fixed on the fixing ring, and the cable can be quickly unfolded for fire resistance detection operations without manually straightening the cable, thereby reducing the operating difficulty of the operator and improving the efficiency of the detection.

[0019] 2. The present invention can comprehensively burn the cable and then test its fire resistance by arranging multiple groups of exhaust ports on the inner side of the annular tube on the annular sleeve. The annular design enables the flame to form a uniform heating circle around the cable to ensure that all parts of the cable are heated evenly, which helps to more accurately evaluate the fire resistance of the cable at different temperatures. Uniform heating avoids local overheating of the cable or the generation of hot spots, thereby reducing the risk of cable damage due to uneven thermal stress.

[0020] 3. The present invention, through the setting of the collecting bottom bin, when the cable is subjected to fire resistance test, unqualified cables will drop particles into the water source in the water source storage chamber for direct cooling, thereby preventing the particles from adhering to the equipment due to excessive temperature. At the same time, the particles can be filtered and swept into the solid collection chamber by the filter screen during each test, so that the particles generated by combustion can be collected in a centralized manner, thereby preventing the particles from scattering around the detector or in the working area, and reducing the difficulty and complexity of the cleaning work.
