[0034] Working principle: After the staff installs the guardrail 2, the water supply pipe 4 is connected through the connecting flange 9, and then the water is pumped into the inner cavity of the water supply pipe 4 by using an external water pump. The water in the inner cavity of the water supply pipe 4 flows into the nozzle 6 through the hose 5 and is sprayed out, which can spray water to remove dust in the surrounding environment. At the same time, in the process of spraying water to reduce dust, the staff uses the external control switch to start the motor 701, and the output end of the motor 701 drives the first synchronous wheel 702 to rotate. When the first synchronous wheel 702 rotates, it drives the belt to transmit. When the belt transmits, it drives the second synchronous wheel 703 to rotate. The second synchronous wheel When 703 rotates, it drives the limit rod 704 to rotate. When the limit rod 704 rotates, it drives the half gear 705 to rotate. After the half gear 705 rotates and meshes with the circular gear 706, it can drive the circular gear 706 to rotate. When the circular gear 706 rotates, it drives the positioning rod 3 to rotate.

With the cooperation of 707, the reciprocating movement of the nozzle 6 can be realized, thereby increasing the dust reduction range of the nozzle 6, and in the process of installing the guardrail 2, the rocker 804 is rotated, and the rocker 804 drives the first bevel gear 803 to rotate when it rotates, and the first bevel gear 803 drives the second bevel gear 805 to rotate when it rotates, and the second bevel gear 805 drives one of the two-way screw rods 802 to rotate when it rotates, and one of the two-way screw rods 802 drives one of the third synchronous wheels 806 to rotate when it rotates, and one of the third synchronous wheels 806 drives the leather The belt is used for transmission, and the belt drives another third synchronous wheel 806 to rotate during transmission. The other third synchronous wheel 806 drives another bidirectional screw rod 802 to rotate during rotation. The two bidirectional screw rods 802 drive four threaded sleeves 807 to move during rotation. The four threaded sleeves 807 drive one end of four support rods 809 to move during movement. At this time, the other end of the support rod 809 supports upward and drives the positioning frame 810 to move upward, so that the height of the guardrail 2 can be adjusted. While improving the protection performance of the guardrail 2, the dust reduction range of the nozzle 6 can also be increased.
