The utility model provides a movable dust control spraying device which comprises a liquid storage box and a spraying assembly, the upper surface of the liquid storage box is fixedly connected with an air pump and a fixed cylinder respectively, the upper surface of the fixed cylinder is fixedly connected with a flow dividing box, the air outlet end of the air pump is communicated with an inner cavity of the fixed cylinder, and the bottom of an inner cavity of the liquid storage box is fixedly connected with a liquid pump. The liquid pump is communicated with an inner cavity of the flow dividing box through a liquid conveying pipe, the spraying assemblies are symmetrically connected to the outer side face of the flow dividing box, the electric rods are symmetrically connected to the lower surface of the flow dividing box, telescopic rods of the electric rods are fixedly connected with extension pipes in the spraying assemblies through push plates, and each spraying assembly is composed of a guide pipe, an extension pipe, a reinforcing cylinder and a flow dividing ring. One end of the guide pipe is fixedly connected to the outer side of the shunting box. Through cooperation of the shunting box, the fixing cylinder, the air pump, the electric rod and the spraying assembly, the device can spray water mist at multiple angles, the water mist diffusion distance can be increased, the coverage range of the water mist can be enhanced in an auxiliary mode, and therefore the flying dust treatment effect is enhanced.

The application relates to the technical field of passive protection of spacecraft, and particularly relates to a deployable impact protection system for space objects. The system comprises: a plurality of elastic support rods for forming an energy storage and deployment structure; a protection unit array comprising a plurality of protection units, which are arranged on the elastic support rods, each protection unit comprising a buffer layer, a filling layer and a back wall; a chain release mechanism for restraining the elastic support rods in a compressed state and uniformly releasing the restraint after receiving a release instruction; a gap filling mechanism arranged between the buffer layers of adjacent protection units to fill the gap between the adjacent units caused by deployment; and a lock mechanism for locking and detachably connecting the protection units. The application significantly increases the spacing between the buffer layer and the cabin wall through large-stroke deployment of the super-elastic rod, thereby improving the high-speed impact protection capability of the spacecraft against space debris. Meanwhile, the system adopts a modular protection unit design, can replace damaged units in orbit, and has the advantages of simple structure, light weight, high reliability and convenient maintenance.
