Control device 9 respectively with scanned imagery device 2, lifting drive, horizontal drive apparatus, axial drive means and
Rotation drive device 6 is electrically connected.
When installing as a result: firstly, to control device 9, scanned imagery device 2, lifting drive, horizontal drive apparatus,
Rotation drive device 6 and axial drive means carry out energization test, and exclude corresponding failure；Then, bobbin carriage will have been removed
Heat exchanger, that is, heat exchanger to be cleaned core 10 is placed into rotation drive device 6；Finally, spray boom 8 is connected to external fluid delivery conduit.
When use:
Firstly, starting scanned imagery device 2, to obtain the 3-D image of the core 10 of heat exchanger to be cleaned.Specifically, such as
Plane shown in Fig. 3, in core 10 of the scanned imagery device 2 by scanning heat exchanger to be cleaned where same layer heat exchanger tube 10-1
The core 10 of internal diameter, quantity and the arrangement mode and heat exchanger to be cleaned of angle, heat exchanger tube 10-1 between horizontal plane
Caliber and length just produce the 3-D image of the core 10 of heat exchanger to be cleaned.
Then, control device 9 controls lifting drive, water according to the 3-D image of the core 10 of heat exchanger to be cleaned
Flat driving device, rotation drive device 6 and axial drive means execute corresponding actions.Specifically, when the core of heat exchanger to be cleaned
When there is angle between plane and horizontal plane in body 10 where same layer heat exchanger tube 10-1, that is to say, that heat exchanger to be cleaned
Core 10 in plane and not parallel horizontal plane where same layer heat exchanger tube 10-1 when, the just control rotation driving of control device 9
Device 6 starts, so that after the core 10 of heat exchanger to be cleaned rotates specified angle under the driving of rotation drive device 6, cleaning
Plane and horizontal plane keeping parallelism in the core of heat exchanger where same layer heat exchanger tube 10-1.When the core of heat exchanger to be cleaned
The height of heat exchanger tube 10-1 to be cleaned and when the not identical height of spray boom 8 in 10, i.e., the axis of heat exchanger tube 10-1 to be cleaned and spray
For the axis of bar 8 not in same level, control device 9 controls lifting drive starting；Due to horizontal drive apparatus and axis
Moved synchronously to driving device and lifting drive, therefore, when lifting drive driving horizontal drive apparatus upwards or to
When lower mobile, axial drive means are mobile simultaneously therewith, so the spray boom 8 being placed in axial drive means gradually level off to
The plane where heat exchanger tube 10-1 is cleaned, until the axis of heat exchanger tube 10-1 to be cleaned and the axis of spray boom 8 are in same level.
As heat exchanger tube 10-1 to be cleaned and not coaxial spray boom 8, i.e., when spray boom 8 is located at the left or right side of heat exchanger tube 10-1 to be cleaned,
9 controlled level driving device of control device starting so that axial drive means horizontal drive apparatus driving lower edge perpendicular to
After the axial movement of spray boom set 7 is moved to the left or right specified level distance, heat exchanger tube 10-1 and spray boom 8 to be cleaned are coaxial.
As heat exchanger tube 10-1 to be cleaned and coaxial spray boom 8, control device 9 controls axial drive means driving spray boom 8 and moves forward the
One distance to a declared goal, i.e. driving spray boom 8 are towards mobile first distance to a declared goal of heat exchanger tube 10-1 to be cleaned, and spray boom 8 is in heat exchanger tube to be cleaned
In 10-1 during movement, spray boom 8 can constantly spray clear water to rinse the dirt on the inner wall of heat exchanger tube 10-1 to be cleaned
Get off.
Then, control device 9 control axial drive means driving spray boom 8 move backward the second distance to a declared goal, with exit to
Clean heat exchanger tube 10-1.
Next, control device 9, which controls lifting drive, horizontal drive apparatus and axial drive means, repeats above-mentioned step
It is rapid to clean remaining heat exchanger tube 10-1 one by one.
Finally, after all heat exchanger tube 10-1 cleanings, so that it may which the core 10 of heat exchanger to be cleaned is hung rotation driving
Device 6.
The present invention passes through the 3-D image that scanned imagery device 2 obtains the core 10 of heat exchanger to be cleaned first；Then lead to
10 autobiography of core that rotation drive device 6 drives heat exchanger to be cleaned is crossed, makes to clean same layer heat exchanger tube in the core of heat exchanger
Plane and horizontal plane keeping parallelism where 10-1；It drives followed by lifting drive and is moved down on horizontal drive apparatus
Dynamic, the axis of the axis and spray boom 8 that make heat exchanger tube 10-1 to be cleaned is in same level；Then it is driven by horizontal drive apparatus
Dynamic axial drive means move left and right, and keep heat exchanger tube 10-1 and spray boom 8 to be cleaned coaxial；It is driven finally by axial drive means
Spray boom 8 moves axially back and forth along spray boom set 7, and then achieves that quick, accurate, the efficient cleaning of exchange heat pipe 10-1, from
And requirement, the raising safety to staff's operation level can be not only reduced, but also the labor of staff can be significantly reduced
