[0032] Connecting unit includes several first joints 52 and several second joints 622, each second joint 622 is fixedly connected on mounting seat 62 and is arranged on the horizontal direction of mounting seat 62, the mounting seat 62 connected with the atomizing nozzle 63 close to the end of tower crane arm 2 is sealed on the side away from water belt 51.

[0033] The one end of water belt 51 close to the side of tower body 1 is communicated with water delivery pipe 4, and the other end of water belt 51 close to the side of tower body 1 is fixedly connected with snap ring 53 at the end of each water belt 51 respectively, each first joint 52 is rotatably sleeved on snap ring 53, each snap ring 53 is attached to the bottom wall inside first joint 52, and water stop pad 54 is arranged between each snap ring 53 and second joint 622, each first joint 52 and second joint 622 are screw-connected, and water passage 621 is formed in each mounting seat 62, and each water belt 51 is communicated with water passage 621.

[0034] Each mounting base 62 is provided with a valve body 65, which comprises a valve plate 652 and a top rod 632. The water passage 621 is provided with a valve plate accommodating hole 625 on one side close to the sliding base 61, and is provided with a valve seat 624 on one side close to the atomizing nozzle 63. The top and bottom of the valve plate 652 are respectively fitted with the valve plate accommodating hole 625 and the valve seat 624. The bottom of the valve plate 652 is chamfered at each corner and is provided with a slope surface. The excess water in the water passage 621 is reduced in the valve seat 624 by the slope surface. At the same time, the bottom of the valve plate 652 is more tightly fitted with the surface of the valve seat 624 during the process of moving downward and clamping into the valve seat 624, and the process of clamping the valve plate 652 is more smooth.

[0035] The valve plate accommodating hole 625 is sequentially provided with a spring 653 accommodating hole and a guide hole 627 upwardly. The valve plate accommodating hole 625, the spring mounting hole 626 and the guide hole 627 are respectively formed in an annular stepped shape. The top of the valve plate 652 is fixedly connected with a valve rod 651. The valve rod 651 is sleeved with the spring 653. The two ends of the spring 653 are respectively fixedly connected with the spring mounting hole 626 and the top of the valve plate 652. The valve rod 651 is slidingly connected in the guide hole 627.

[0036] The bottom of each mounting base 62 is fixedly connected with a third connector 623. Each atomizing nozzle 63 is fixedly connected with a connecting ring 631. Each connecting ring 631 is threadedly connected with the third connector 623. Each top rod 632 is fixedly connected with the atomizing nozzle 63. The length of the top rod 632 is the same as the distance from the atomizing nozzle 63 to the bottom of the valve plate 652 when the valve plate 652 is located in the valve plate accommodating hole 625.

[0037] The implementation mode of the embodiment is that: in use, the number of the atomizing nozzles 63 can be selected according to actual needs. At the position where the atomizing nozzle 63 is installed, the atomizing nozzle 63 and the connecting ring 631 are rotated, so that the connecting ring 631 is gradually screwed on the third connector 623. The top rod 632 on the atomizing nozzle 63 moves upward with the atomizing nozzle 63, and the valve plate 652 is lifted upward. The valve rod 651 is slidingly upward in the guide hole 627 under the driving of the valve plate 652. The spring 653 on the top of the valve plate 652 is gradually compressed in the spring mounting hole 626. Until the connecting ring 631 is screwed, the valve plate 652 is completely in the valve plate accommodating hole 625. The water hose 51, the water passage 621 and the water outlet end of the atomizing nozzle 63 are in communication, so as to meet the requirement of water passing.

[0038] In the position where the atomizing nozzle 63 is not installed, the third joint 623 on the mounting seat 62 is in the open state, the spring 653 is in the initial stretched state, the spring 653 drives the valve plate 652 to move downward and makes the valve plate 652 clamped in the valve seat 624, the valve plate 652 drives the valve rod 651 to slide downward in the guide hole 627, at this time the water passage 621 and the third joint 623 are separated by the valve plate 652, the water in the water hose 51 cannot flow out from the third joint 623, and water leakage does not occur.

[0039] When the atomizing nozzle 63 needs to be repaired or replaced due to damage, the control driving motor 74 is started, the driving motor 74 drives the driving wheel 71 to rotate, the driving wheel 71 drives the driven wheel 72 to rotate, and the conveyor belt 73 starts to run in the clockwise direction. Although each fixed part 64 is slidably sleeved on the conveyor belt 73, due to the gravity of the sliding seat 61, the mounting seat 62 and the fixed part 64, a certain traction force in the direction of the ground is generated on the conveyor belt 73, and each fixed part 64 gradually approaches the first wheel seat 22 direction following the conveyor belt 73, at this time the sliding seat 61 slides in the track 21 and gradually approaches the tower body 1, the water hose 51 between the atomizing nozzle 63 closest to the tower body 1 and the water delivery pipe 4 is gradually folded downward.

[0040] When the sliding seat 61 closest to the tower body 1 abuts against the blocking plate 24, the fixed part 64 remains stationary relative to the sliding seat 61, the conveyor belt 73 continues to run, and the fixed part 64 slides relative to the conveyor belt 73, and then the water hose 51 between the second atomizing nozzle 63 from the tower body 1 and the first atomizing nozzle 63 gradually folds downward, and then the mounting seat 62 and the first joint 52 connected to the second atomizing nozzle 63 no longer slide when they touch the mounting seat 62 and the first joint 52 of the first atomizing nozzle 63 which has been stationary. Similarly, the fixed parts 64 connected to the stationary sliding seat 61 are also stationary and slide relative to the conveyor belt 73.

[0041] By analogy, all the water hoses 51 between the atomizing nozzles 63 are folded, and each atomizing nozzle 63 is compactly gathered near the tower body 1 and arranged in sequence, at this time people can remove the atomizing nozzle 63 that needs to be repaired or replaced at a position close to the tower body 1, avoiding climbing along the tower boom 2 to the position of each atomizing nozzle 63 for processing.

[0042] When the atomizing nozzle 63 is repaired or replaced, the driving motor 74 is controlled to rotate reversely, at this time the driving wheel 71 and the driven wheel 72 also rotate reversely, the transmission belt 73 runs in the counterclockwise direction. Under the drive of the transmission belt 73, each fixed part 64 moves with the transmission belt 73 and gradually moves away from the tower body 1, the sliding seat 61 slides in the track 21 to move away from the tower body 1, the first sliding seat 61 closest to the tower body 1 gradually stretches the water hose 51 connected with the mounting seat 62 during the sliding process, since the water delivery pipe 4 remains stationary, when the water hose 51 is fully stretched, the first sliding seat 61 no longer slides, so that the fixed part 64 connected therewith also remains stationary and slides with the transmission belt 73. When the water hose 51 between the first atomizing nozzle 63 and the second atomizing nozzle 63 closest to the tower body 1 is fully stretched, the fixed part 64, the sliding seat 61 and the mounting seat 62 are all restrained by the water hose 51 and no longer move.

[0043] By analogy, each stationary spraying mechanism 5 restrains its adjacent moving spraying mechanism 5 and keeps it stationary until all the water hoses 51 between the atomizing nozzles 63 are fully stretched and each atomizing nozzle 63 is uniformly distributed on the tower crane arm 2, at this time the water delivery pump 3 on the ground is started, the water flow for dust reduction can enter the water hose 51 through the water passage 621 from the water outlet of the atomizing nozzle 63 to achieve the purpose of dust reduction on the construction site.

[0044] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
