Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Following instance
For illustrating the present invention, but it is not limited to the scope of the present invention.
As shown in Figure 1 and Figure 2, the present invention discloses a kind of blower fan tower barrel cleaning equipment 100 of variable cleaning radius, is nested with
On blower fan tower barrel 200, including cleaning chain 1 and circular base 2, clean chain 1 and be connected by link 3 with circular base 2, clean chain
3 have expansion ring 4, and expansion ring 4 can change the size of diameter itself, such that it is able to adapt to the tower 200 of various outer diameter, realize
Cleaning to tower 200.Cleaning device 6 is additionally provided with the expansion ring 4 of the cleaning chain 1.
As shown in Figure 3, Figure 4, below illustrate expansion ring 4 structure, in a kind of optional embodiment, expansion ring 4 by
The head and the tail connection composition loop configuration of multiple scissor groups 5, scissor group 5 includes：First bar 51 and the second bar 52 of cross-articulation, and
3rd bar 53 of cross-articulation and the 4th bar 54；One end of first bar 51 is connected with one end of the 3rd bar 53, and the one of the second bar 52
End is connected with one end of the 4th bar 54；The other end of the first bar 51 in each scissor group 5, with adjacent scissor group 5
The other end connection of three bars 53；The other end of the second bar 52 in each scissor group 5, with the 4th bar in adjacent scissor group 5
54 other end connection.
According to the different position of above-mentioned cleaning, cleaning device 6 can be arranged on the inner face of the first bar 51, can also be first
The outside of bar 51 is (because of hereafter carrying out another description, therefore the describing mode to expansion ring above to expansion ring, referred to as
The first describing mode).
Certainly, it is a kind of optional embodiment that the first bar of above-mentioned selection 51 arranges cleaning device 6, the main space for considering
Layout, prevents excessive cleaning structure from affecting the diameter change of expansion ring.In some embodiments, completely can be in each bar
On cleaning device 6 is all set, or arbitrarily select to arrange cleaning device 6 on which bar.
General, when the first bar 51 is as cleaning rod, its size can be larger than other bodies of rod, and to facilitate peace is chosen
Dress.During described above expansion ring, in order to clearly illustrate how that (i.e. above-mentioned " arranges clear to setting cleaning device 6 on the first bar
Cleaning device "), therefore four bodies of rod are defined as into a scissor group 5.
In certain embodiments, the first bar 51 can not be chosen as the mounting rod for installing cleaning device 6, can be arbitrarily selected
Selecting the body of rod, and be provided with the body of rod of cleaning device 6 also not necessarily needs the change of size, therefore, it is every in expansion ring 4
The body of rod that the individual body of rod can be just as, carries out scissor connection.
It is to be understood that it is that for convenience of explanation, four bodies of rod completely can be with that four bodies of rod of above-mentioned definition are scissor group 5
It is the isostructural body of rod of same size, therefore, below with another describing mode explanation expansion ring 4.
Another kind of description to expansion ring 4：Expansion ring 4 is made up of scissor group 5, and scissor group 5 includes：The first of cross-articulation
The bar 52 of bar 51 and second；The two ends of the first bar 51 in each scissor group 5 respectively with the second bar in two adjacent scissor groups 5
52 connections；The two ends of the second bar 52 in each scissor group 5, connect respectively with the first bar 51 in two adjacent scissor groups；
Multiple scissor groups 5 are sequentially connected and circularize.It is noted that this specification is hereafter, if being all with the first without specified otherwise
Illustrate based on describing mode (i.e. scissor group is made up of four bodies of rod).(in order to distinguish, this describing mode is referred to as into
Two kinds of describing modes)
Certainly, because above-mentioned scissor group 5 in a ring, therefore, the junction of each body of rod can be connected using spherical hinge 7
Connect, it is ensured that the combination of annular can be realized.
In order to ensure the telescopicing performance of expansion ring 4, tension structure 9 can also be set, for controlling the flexible of expansion ring 4.
Explained below, is carried out based on the first describing mode.
Can also arrange on the above-mentioned body of rod (two bodies of rod in four bodies of rod in the first description, or second description)
Limited roller 8 so that cleaning chain 1 can be carried out spacing during contacting to the surface of tower 200 by limited roller 8
With elastic rolling contact, prevent the surface of 1 scratch tower of cleaning chain 200 and control the distance of cleaning device 6 and the surface of tower 200,
So as to control the cleaning dynamics of cleaning device 6, specific cleaning device 6 is described below, but no matter cleans or rinse, with
The distance of tower 200 can all affect cleaning performance.
With the first bar 51 and the hinged place of the second bar 52 as the first pin joint 55, it is with the 3rd bar 53 and the hinged place of the 4th bar 54
Second pin joint 56, between the first pin joint 55 and the second pin joint 56 tension structure 9 is provided with, for shrinking expansion ring 4.
Because expansion ring 4 has multiple scissor groups, above-mentioned first pin joint and the second pin joint can be adjacent, or be separated by
, it is generally preferable to selection it is adjacent two.
If based on second describing mode, then for：Made with the hinged place of the first bar 51 of cross-articulation and the second bar 52
For pin joint, two are chosen in pin joint that is adjacent or being separated by, tension structure 9 is set.
