The invention discloses a tower crane spraying system. Each spray head assembly comprises a cylindrical shell and blocking pieces. An opening is formed in the top end of the shell, at least one circleof spray holes are formed in a penetrating mode with the center of the bottom face of the shell as the circle center, the spray holes are formed at equal intervals, the longitudinal section of each spray hole in the radial direction is a right trapezoid, and the inclined side walls of the spray holes are arranged in the direction away from the center of the bottom face of the shell from top to bottom. Each blocking piece comprises a hole plug, a connecting rod and a circular sieve tray, the hole plugs are the same as the spray holes in shape and height, the vertical side wall of the hole plugs and the corresponding vertical side wall of the spray holes are in sliding seal connection, and holes are reserved between the inclined side walls of the hole plugs and the inclined side walls of the spray holes, wherein each sieve tray is connected with a driving mechanism, and the driving mechanism drives the sieve tray to slide in the vertical direction. By adjusting the sizes of the spray holes, under the condition that the flow is fixed, the flow is adjusted by adjusting the sizes of the spray holes, the coverage area of umbrella-shaped water mist sprayed by the spray head assemblies under the condition of a certain height is controlled, and operation is easy and convenient.

    本发明公开了一种塔吊喷淋系统,每个喷头组件包括:壳体,其为圆柱状,且顶端设有开口,以壳体底面中心为圆心贯穿设有至少一圈喷孔,每圈喷孔等间隔设置,每个喷孔径向方向的纵截面为直角梯形,喷孔的倾斜侧壁由上至下远离壳体底面中心的方向设置;堵件,其包括孔塞、连接杆、圆形筛盘,孔塞形状与喷孔形状相同,且高度相同,孔塞竖直侧壁与喷孔对应竖直侧壁滑动密封,孔塞倾斜侧壁与喷孔倾斜侧壁之间留有孔隙;其中,筛盘连接有驱动机构,驱动机构带动筛盘在竖直方向上滑动。本发明能够通过调节喷孔大小,在流量一定的情况下,通过喷孔大小调节以调节流量,来控制一定高度条件下喷头组件喷洒出的伞状水雾覆盖面积大小,操作简便。
