The cylinder 617, the piston rod 618 and the piston 6180 are all of conventional structures. The axis of the cylinder 617 is distributed along the radial direction of the fixed rod. The piston rod 618 and the cylinder 617 are in a conventional movable fit. The space of the cylinder 617 at the top of the piston communicates with the external air. Preferably, a friction layer can also be mounted on the inner wall of the special-shaped cavity 614.

[0048] In this embodiment, when the protective panel 2 bears the impact of flying stones, the protective panel 2 first buffers the impact through its own structure. At the same time, under the action of the impact force, the protective panel 2 moves into the panel mounting part 4, so that the damping buffer rod 60 and the linkage rod 610 contract. During the contraction process of the damping buffer rod 60, the impact energy is consumed through fluid damping. During the contraction process of the linkage rod 610, the rack is driven to move. The movement of the rack causes the linkage gear 612 meshing with it to rotate. The rotation of the linkage gear 612 drives the rotation of the rotating shaft, thereby causing the friction disc 613 to rotate. During the rotation of the friction disc 613, under the action of the spring 6110, the piston rod 618 makes the friction block 6181 always abut against the inner wall of the special-shaped cavity 614, so that friction is generated between the friction block 6181 and the inner wall of the special-shaped cavity 614. The energy generated by the impact is converted into heat energy through friction, thereby consuming the impact energy and improving the protective effect against the impact of flying stones. At the same time, during the rotation of the friction disc 613, due to the special-shaped structure of the special-shaped cavity 614, the piston rod 618 reciprocates with the rotation of the friction disc 613, causing the piston to reciprocate in the cylinder 617 and squeeze the air in the inner cavity of the fixed shaft 616. Thus, the air in the cavity is pressed through the one-way air outlet 6160 and the pipeline to the compressed gas cylinder 74 to supplement the compressed air in the compressed gas cylinder 74, reducing the consumption of the external gas source 75 and effectively utilizing the impact energy.

[0049] Example 7: This embodiment provides an engineering blasting comprehensive protection device. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The flow guide cover 70 further includes: a housing 700, which is composed of a first air duct section 701, a second air duct section 702, and a third air duct section 703 connected in sequence. A fluid outlet is provided at the end of the third air duct section 703; a flow guide vane group 704, which is arranged inside the housing 700. The flow guide vane group 704 includes at least two flow guide vanes symmetrically distributed along the length direction of the housing 700. The distance between the two flow guide vanes increases along the fluid flow direction; a flow dividing grid 705, which is arranged in the fluid outlet at the end of the third air duct section 703. The flow dividing grid 705 is composed of several grid plates extending along the length direction of the housing 700 and equally spaced along the width direction of the housing 700; Among them, several atomizing nozzles 71 are arranged at the starting end of the first air duct section 701. The width of the first air duct section 701 gradually decreases along the fluid flow direction. The width of the second air duct section 702 gradually increases along the fluid flow direction. The width of the third air duct section 703 gradually decreases along the fluid flow direction. A buffer gap is reserved between the flow guide vane group 704 and the several atomizing nozzles.

[0050] In this embodiment, after the atomizing nozzle sprays atomized water, the atomized water moves with the airflow from the starting end of the first air duct section 701 to the fluid outlet of the third air duct section 703. Through the design that the width of the first air duct section 701 gradually decreases along the fluid flow direction, the width of the second air duct section 702 gradually increases along the fluid flow direction, and the width of the third air duct section 703 gradually decreases along the fluid flow direction, the atomized water repeatedly collides with the inner wall of the air duct and diffuses during the flow process due to the continuous change of the air duct width, so that the atomized water is fully distributed in the flow guide cover 70. The arrangement of the flow guide vane group 704 further improves the distribution uniformity of the atomized water. When the uniformly distributed atomized water is ejected from the fluid outlet, the atomized water can form multiple layers of water curtains under the action of the shunt grid 705, thereby further improving the protection effect against dust. Compared with the prior art, the present invention enables the atomized water ejected by the atomizing nozzle to effectively form a planar water mist through the arrangement of the flow guide cover 70, and can form multiple planar water mists, improving the protection effect against dust.
