[0060] The working principle of this portable coal mine electromechanical installation protection device is as follows:

[0061] The operator first starts motor 10, which drives the left lead screw 12 to rotate. The left lead screw 12 then drives its upper sprocket 13 to rotate, which in turn drives another sprocket 13 via chain 14, thus driving the right lead screw 12 to rotate. The two lead screws 12 cause the sliding rod 7 to extend and retract within the second support column 6, bringing the caster wheel 8 into contact with the ground. Then, motor 10 is turned off, and the device is moved to the corresponding equipment. The electromechanical equipment is installed in the electromechanical box 21, and the box door 23 is closed. Then, motor 10 is started again in reverse, causing the sliding rod 7 to retract into the second support column 6, thus... The first support 2 is in contact with the ground, and the pin 5 passes through the through hole 4 on the side plate 3 and is inserted into the ground to fix the entire device on the ground, ensuring the stability of the entire device and preventing the device from tipping over. When the crushed stone from the top of the coal mine falls onto the roof 19, it can slide down along the slope of the roof 19 without being crushed by the accumulation of crushed stone. The impact vibration generated by the falling crushed stone hitting the roof 19 is transmitted from the roof 19 to the spring damping shock absorber 20. The spring damping shock absorber 20 dampens the vibration and prevents the electromechanical box 21 from vibrating frequently and damaging the electromechanical equipment inside the box.

[0062] This utility model provides a portable protective device for coal mine electromechanical installations. By installing a canopy on top of the electromechanical box, direct contact between gravel and the box can be avoided. At the same time, the spring-damped shock absorber reduces the impact of gravel on the canopy, thus reducing the probability of damage to the electromechanical equipment. The V-shaped structure of the canopy can prevent the accumulation of gravel from collapsing the canopy and extend its service life.
