[0025] In order to cooperate with the top translation adjustment, the top-mounted adjusting guide rail 2 comprises a horizontal main guide rail 21 fixedly arranged at the central position of the inner top surface of the external shell 1 and horizontal side guide rails 22 fixedly connected on both sides of the horizontal main guide rail 21.

[0026] In order to cooperate with the lifting adjustment and lateral heat absorption, the side-mounted adjusting guide rail 3 is movably assembled with an electric control type screw rod lifting platform and a roller shutter adjusting assembly controlled by the electric control type screw rod lifting platform, and an embedded top suction heat sink 6 is fixedly assembled on the inner wall of the side-mounted adjusting guide rail 3.

[0027] The electric control type screw rod lifting platform is initially arranged at the inner upper end of the side-mounted adjusting guide rail 3.

[0028] Working principle: in the initial state, the self-propelled electric control adjusting module 4 is arranged at the middle part of the external shell 1, when temperature abnormality occurs inside, the self-propelled electric control adjusting module 4 is translated to the side of the temperature abnormality, the monitoring mode of the temperature abnormality is to judge through the temperature change of the air sucked by the heat pump. Then the self-propelled electric control adjusting module 4 is translated to the upper end of the temperature abnormality position, the split-type temperature measurement and adjusting mechanism 5 is translated outward, then moved to the opening at the upper end of the side-mounted adjusting guide rail 3, then lowered by the electric control type screw rod lifting platform, then longitudinally measures the temperature, finally finds the abnormal heating point, and then quickly pumps and cools at the fixed point.

[0029] In order to cooperate with the translation adjustment, the self-propelled electric control adjusting module 4 comprises a top translation car frame 41 arranged in the top-mounted adjusting guide rail 2, main support wheels 42 and main drive wheels 43 mounted on both sides of the top translation car frame 41.

[0033] By activating the electromagnet 45, the first auxiliary frame 51 and the second auxiliary frame 52 are fixedly adsorbed on one side of the internal limiting frame 44, so that they can be firmly fixed inside the top translation frame 41.

[0034] In order to cooperate with the angle adjustment, the infrared temperature measurement probe 53 and the built-in support rod 54 are movably mounted inside the first auxiliary frame 51 and the second auxiliary frame 52 through the two side assembly shafts, and the infrared temperature measurement probe 53 has a bottom control bracket at the lower end for movably connecting the extension end of the built-in support rod 54.
