The specific working steps are as follows:
when a large amount of dust is generated in the construction behind the railing 3, the cover 302 is unscrewed in advance to fill the water collection box 301 with water, and then the cover 302 is screwed back, so that the construction can be performed;
because the construction time is generally daytime, under the condition of poor visual field environment such as rainy days or night, in order to ensure the safety of workers, the construction can be stopped, so the light lamp 107 can not be used in the construction, at the moment, the electric rotating plate 106 can drive the light lamp 107 to rotate clockwise in a overlooking angle and rotate to a longitudinal state, the electric rotating plate 106 can also drive the gear 311 to rotate clockwise in a overlooking angle, the gear 311 rotates to push the front rack 312 and the rear rack 312 to move, thereby driving the front third water baffle 313 and the rear third water baffle 313 to move left and right respectively, thereby driving the two third water baffles 313 to drive the connected baffle hole blocks 314 to move, leading the baffle hole blocks 314 close to the third water delivery groove 106a to block the third water delivery groove 106a, simultaneously, the water pump 303 starts to suck water in the water collection box 301 through the water outlet 301b and then is conveyed into the upper first water outlet hole 2b and the lower first water outlet hole 2b, then, the water is conveyed into the first water conveying groove 3a and the second water conveying groove 3c through the upper water outlet hole 2b and the lower water outlet hole 2b, the water conveyed into the first water conveying groove 3a flows to the first water collecting groove 3b, the first water collecting groove 3b is blocked by the first water baffle 304, the water flowing into the first water collecting groove 3b is accumulated, when the first water conveying groove 3a and the second water conveying groove 3c are filled with the water, the water pump 303 can continue to convey the water, when the pressure of the water in the first water conveying groove 3a and the second water conveying groove 3c is higher than the hardness of the first water baffle 304, the pressurized water can squeeze the first water baffle 304 to deform the first water baffle 304, so that the first water baffle 304 is not contacted with the railing 3, the water is sprayed out of a gap between the first water baffle 304 and the railing 3, and is sprayed on the fog lamp 108, and the fog lamp 108 is prevented from being adhered with a large amount of dust, so that the lighting effect is poor; when the second water delivery tank 3c and the second water collection tank 3d are fully filled with water, the third water outlet 313a of the front and rear first water baffle plates 304 is in a staggered state, the electric rotating plate 106 drives the gear 311 to rotate, so that the gear 311 pushes the rack 312 to move, the rack 312 drives the third water baffle plate 313 to move, the rear third water outlet 313a is communicated with the rear water outlet 3e, the front third water outlet 313a is not communicated with the front water outlet 3e, and at the moment, the water in the second water collection tank 3d is sprayed out from the water outlet 3e which is not blocked by the first water baffle plate 304, so that dust generated in the construction direction is reduced, the barrier 3 is isolated between construction and a road, the dust is prevented from being sucked into the body by pedestrians, the third water delivery tank 106a is blocked by the barrier block 314, and the second water delivery tank 3c cannot flow into the third water delivery tank 106 a; it should be noted that, when the water pump 303 is delivering water, the water outlet of the water pump 303 is parallel to the first water outlet hole 2b below, and when the delivered water flows, as the first water outlet hole 2b below is parallel to the water flow direction, more water flows into the second water delivery tank 3c when the water flows, and as the first water outlet hole 2b above is perpendicular to the water outlet of the water pump 303, the water flowing into the first water outlet hole 2b above is blocked, and the second water delivery tank 3c and the second water collection tank 3d obtain most water, so that the first water delivery tank 3a and the first water collection tank 3b need long-time water collection and pressurization to clean the fog lamp 108, so that most water is used for dust precipitation, and the water utilization efficiency is improved;
when the night or rainy day comes, dust adheres to the illumination lamp 107 due to daytime construction or the illumination effect of the illumination lamp 107 is poor due to the fact that accumulated water splashes onto the illumination lamp 107, so that when the electric rotating plate 106 rotates back to the illumination state, the blocking hole block 314 is far away from the third water conveying groove 106a, so that water in the second water collecting groove 3d flows into the third water collecting groove 106b through the third water conveying groove 106a, the second water blocking plate 305 blocks the water in the third water collecting groove 106b, the water in the third water collecting groove 106b is more and more, and when the water pressure above the second water blocking plate 305 is strong enough, the second water blocking plate 305 is pressed downwards to deform the water blocking plate 305, the second water blocking plate 305 rotates downwards, a gap exists between the second water blocking plate 305 and the electric rotating plate 106, and the water is sprayed out of the gap, so that the illumination lamp 107 is washed; meanwhile, the electric rotating plate 106 drives the third water baffle 313 to move, and the movement of the third water baffle 313 can lead the third water outlet 313a at the front and back to be not communicated with the water spraying hole 3e at the front and back, so that the water spraying hole 3e does not spray water any more, and dust fall operation is not carried out when the construction state is not carried out, thereby reducing the waste of water;
based on the above operation, if only the water spraying hole 3e at the rear of the railing 3 is opened, although the railing 3 can be placed in front of the construction area during placement, so that only the water spraying hole 3e at the rear can be subjected to dust fall treatment and the operation of blocking the third water conveying groove 106a, when the railing 3 is required to be placed in a region with more vehicles and narrower roads, in order not to block the normal running of the vehicles, the railing needs to be rapidly placed, when the placement position is present or the railing is taken off from the transport vehicle, the electric rotating plate 106 and the supporting seat 1 can rotate 180 degrees, so that the railing 3 is required to be rotated 180 degrees by a maintainer, so that the water spraying hole 3e at the rear is positioned in the direction of the maintenance area, and at the moment, due to the fact that the road vehicles are more roads and narrower, when the railing 3 is rotated, the road is blocked, even if the pedestrians are cut off the vehicles running, the pedestrians are not rotated, the holes 3e are required to be placed aside, the water spraying holes 3e are sprayed on the road side of the road, and the pedestrians are prevented from being blown out, and the water is sprayed on the road and the road is changed to be the middle of the road, and the water spraying holes are sprayed on the road and the road is avoided; when the front side and the rear side of the railing 3 are provided with the water spraying holes 3e, if the rear water spraying holes 3e are placed on one side of a road, the electric rotating plate 106 drives the third water baffle 313 to move, so that the positions of the front third water spraying holes 313 and the rear third water spraying holes 313a are exchanged, the front water spraying holes 3e can spray water to reduce dust, the rear water spraying holes 3e can not spray water any more, and then the supporting seat 1 is rotated to a proper position, so that the regulation can be realized through rotation no matter what direction the railing 3 is placed, the railing 3 is prevented from being moved again to rotate, the placing time can be shortened, the front and the rear placing is not required to be judged, and road congestion caused by long-time placing is avoided;
it should be noted that, when the water spraying hole 3e formed in front of the railing 3 sprays water and the electric rotating plate 106 is in a longitudinal state, the other blocking hole block 314 of the same blocking hole unit blocks the third water delivery groove 106 a.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
