Connecting plate 32 between structure can be found in structure shown in Fig. 3.The concrete mode that nozzle 2 orderly opens and closes is described below：
As shown in Fig. 2, be a spray boom for being equipped with 8 nozzles 21 and mating inner sleeve 3 is longitudinal split after be launched into
The schematic diagram of plane.Spray boom 1 is followed successively by nozzle one to nozzle eight from top to bottom.Inner sleeve 3 is followed successively by recirculation hole one from top to bottom
To recirculation hole eight, position is corresponded with nozzle one to nozzle eight.For the sake of simplifying and describing, it is assumed that the import of each nozzle 2 is straight
Diameter is all D, and any recirculation hole is fabricated to the strip hole that length is N × D, the code name numerical value phase of the N and nozzle or recirculation hole
Together, as the code name of nozzle three be 3, therefore the length of nozzle three be 3D.It is several situations of each nozzle opening and closing below：
1) when nozzle one is overlapped with recirculation hole one, all nozzle standard-sized sheets：Nozzle one to nozzle eight is kept unimpeded, spray boom
Fluid in inner cavity 11 can be through each nozzle interior aperture and turned on outside.
2) rheme is set to initial bit in the past, and under the action of the drive mechanism, inner sleeve 3 moves upwards the distance of N × D, then flows
Through-hole one is staggered with nozzle one to nozzle N to recirculation hole N, and spray boom inner cavity 11 is separated with outside, and nozzle one to nozzle N seals
It closes, and remaining nozzle is kept unimpeded.
If 3) inner sleeve 3 moves up the distance of 8D, or moves down D, then nozzle one to eight Close All of nozzle.
The typical practical application of the above spray boom 1 is the spray boom 1 for spraying vehicle body side, from top when running
Water inlet, 2 opening time of each nozzle for being located at 1 lower part of spray boom is longer, and superposed nozzle 2 then changes according to bodywork height
And it opens and closes.For example, certain 1 corresponding bodywork height of moment spray boom is 1.0 meters, the nozzle on spray boom 1 higher than 1 meter is nozzle one to spray
Mouth three, it is nozzle four to nozzle eight that height is below herein.Then：It is automatically controlled in the programme control circut of the compositions such as PLC, sensor
Under, servo drive motor 4 rotates, and then inner sleeve 3 is driven to move up 3D distances along screw rod 41, makes inner sleeve 3 by nozzle
One to nozzle three and spray boom inner cavity 11 carrier frequency channel break, these three nozzles then be in closed state；And the aqueous of remaining nozzle can
It sprays unobstructedly.
Certainly, screw rod 41 can also be moved down to realize that same purpose, the trepanning of corresponding recirculation hole 31 must move up,
Principle is identical, does not do analysis description specifically.

Water jets are installed on a vertical line.
To commonly growing the spray boom 1 of 2 meters, internal diameter 25mm, inner wall surface thereof Zhou Changyue 75mm, and formed after the installation of two row nozzles
Aperture about 10mm, according to comparison patent technology, at most simultaneously close off wherein 7 nozzles.And device using the present invention,
In the case where installing 12 nozzles of the same race, injector spacing about 154mm can at most simultaneously close off 15 nozzles, therefore fully meet
Single kind nozzle complete closure, the real needs for being switched to another nozzle.
The arrangement mode of two kinds of nozzles in similar Fig. 7, if spray boom 1 is pipe, two kinds of nozzles of A, B are not vertical at one
On line, requirement certainly will not be met sometimes towards difference.
Shown in Fig. 6, in the present embodiment, spray boom 1 selects square tube, and two kinds of nozzles are installed on the same side, towards identical.This
2 kinds of nozzles on longitudinal straight line, are not controlled respectively by 2 sets of inner sleeves 3 and driving mechanism.At this point, square tube can be therefrom
Portion's water inlet, air-liquid, or it is passed through fluid from the side of end, and respectively fill a set of driving machine on two bottom surfaces of the end of square tube
Structure, specific control mode is similar with embodiment before this to be not described further in detail.
In conjunction with Fig. 7 mode it is found that such square tube using two sets of inner sleeve structures, can at most install, control 4 kinds simultaneously
Nozzle.Such as：The hydraulic spray of small-bore, foam carwash nozzle for liquid, leads to blowing for pressure-air at the reuse (operating) water nozzle of large aperture
Wind nozzle, these 2 directions of nozzle are identical, are mounted on the side of the same square tube.Thus, single by common being equipped with
The mode that more spray booms 1 of nozzle 2 band together is changed to a spray boom 1, greatly reduces spray boom size.
If components such as the end space of square tube one end 2 screw rods 41 of installation enough and corresponding driving mechanisms, spray boom 1 is just
More multigroup inner sleeve and its driving mechanism can be installed, then 1 controllable nozzle number of species of spray boom can also further increase.When
So, rectangular tube or the shape tube that other sides are plane are also suitable the present embodiment situation.
When the cross section of the internal face of spray boom 1 is oval, rectangular and other non-round shapes, without on end cap 5
Limiting through hole 34 in guide post 51 and the connecting plate 32 coordinated with this.
But, even if the cross section of the internal face of spray boom 1 is circle, guide post 51 and the limit with this cooperation can not also be set
Position through-hole 34.At this point, screw rod 41 must be set for the eccentric relative to the center of circle of the cross section of the internal face of spray boom 1, ensure to drive with this
Inner sleeve 3 under the effect of motivation structure will not be driven by torque and rotate in spray boom inner cavity 11, and only along longitudinal direction
It moves in a straight line.
Fig. 8 and Fig. 9 is a kind of 1 embodiment of spray boom intake from middle part.Such spray boom 1 is commonly used in the top spray of car washer
