[0052] A specific application of this embodiment is:

[0053] When it is necessary to protect the crossed circuit, the staff can open the buckle 104, open the device, place the crossed cable 5 on the fixed cover 302, and then close the device. After fixing the upper and lower protective covers through the buckle 104, the motor 403 is remotely started.

[0055] When debris hits the equipment, the rubber protective cover 101 will deform inwards to reduce the impact force caused by the debris. At the same time, the deformation of the rubber protective cover 101 will drive the load-bearing frame 201 to move inwards, and the spring 202 under the load-bearing frame 201 will shrink, further reducing the impact force caused by the debris. At the same time, the inward movement of the load-bearing frame 201 will drive the air pump 204 to shrink and start to inflate the airbag 203. The airbag 203 will protrude upwards due to the gas from the air pump 204, further reducing the impact force caused by the debris, thereby protecting the crossed cable 5.

[0056] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
