step 2: the first screw rod (3) is driven to rotate through the rotating turntable (23), the rotating first screw rod (3) drives the second belt pulley (21) to rotate through the first belt pulley (20) and the driving belt (22), and then drives the second screw rod (4) to rotate, when the first screw rod (3) rotates, the first screw rod nut (5) and the second screw rod nut (6) are enabled to move towards opposite directions at the same time, when the second screw rod (4) rotates, the third screw rod nut (7) and the fourth screw rod nut (8) are enabled to move towards opposite directions at the same time, the moving third screw rod nut (7) and the moving fourth screw rod nut (8) respectively drive the first I-shaped sliding block (10) and the second I-shaped sliding block (11) to move, and under the cooperation of the first screw rod nut (5) and the second screw rod nut (6), the first clamping plate (12) and the second clamping plate (16) are enabled to move towards opposite directions, and further the first air bag (13) and the second air bag (17) are enabled to be respectively contacted with the left side surface and the right side surface of the signal receiving device main body (36);
step 3: then, the first air pump (14) and the second air pump (18) are started, so that the first air pump (14) inflates the first air bag (13) through the first air pipe (15), and the expansion of the first air bag (13) is further increased; the second air pump (18) inflates the second air bag (17) through the second air pipe (19), so that the second air bag (17) is inflated to be larger, and the enlarged first air bag (13) and the second air bag (17) clamp and fix the signal receiving device main body (36);
step 4: then the protective door (24) is closed, the first magnet (26) is contacted with the second magnet (27) and attracted, and the installation of the signal receiving device main body (36) is completed;
step 5: during the use, when needs are cooled down to protection box (1) inside, through start fan (35), with the inside air discharge of protection box (1), and then make outside air enter into inside protection box (1) through breather pipe (31), and then accelerated the inside air flow of protection box (1), thereby cooled down inside protection box (1).
