Background In the automatic coating operation of cables (such as power transmission cables, bridge guys and the like), a spraying device is a key component for realizing efficient and uniform coating. The existing spraying equipment generally adopts a fixed spray head structure, although the basic spraying task can be completed, the spraying equipment has obvious defects under actual high-altitude complex working conditions that a large amount of unattached paint is easy to scatter and waste to cause environmental pollution and material loss, and on the other hand, in order to improve the paint utilization rate, part of the system is provided with a paint recovery cover body structure, but the cover body adopts a rigid closing or motor driving clamping mode, when a robot is accidentally powered off, a control system fails or encounters a special-shaped structure such as a cable joint, mechanical locking is extremely easy to occur, the device is blocked on the cable, the operation is not only interrupted, and serious safety accidents such as equipment falling and the like can be possibly caused. Although some advanced solutions (such as application CN 202510628367) have introduced a linked feed back mechanism to recover excess paint and achieve self-locking by gravity triggering, their closure mechanism is inherently rigid and unidirectional, once the robot stagnates due to power failure, malfunction or encountering a profiled cable, the mechanism permanently locks the equipment onto the cable, and must rely on external unmanned aerial vehicle intervention to get rid of the problem, with serious high-altitude fall risks. Meanwhile, the symmetrical recycling box is designed without considering the characteristic that the paint is mainly concentrated on the dripping of the bottom of the cable due to gravity, so that the recycling efficiency is limited.
