Bindiny mechanism is located at cross bar top when need not dock, and when needing docking, bindiny mechanism is located at the front end of cross bar, so walks
Mechanism is moved to next；Bindiny mechanism and the outlet on connecting pipe top are docking together during connecting pipe, in connecting pipe
Cooling water can be with into bindiny mechanism.The atomization that bindiny mechanism is delivered to cooling water on cannon spray head by connection flexible pipe is sprayed
Head, cooling water atomization is sprayed.And the axial flow blower that the end of cannon spray head is set, water cooling is blowed into transformer, realizes cooling.
Bindiny mechanism includes connecting cylinder, and connecting cylinder is funnel-shaped structure, the inner surface setting elastic sealing layer of connecting cylinder, bullet
The structure of property sealant and connecting cylinder matches.Connecting cylinder docks with the opening of connecting pipe, is carried out by elastic sealing layer
Sealing, after spraying cooling, walking mechanism takes a step back, and afterwards turns over mechanism and overturns connecting cylinder to the top of cross bar,
Walking mechanism bindiny mechanism in moving process just will not touch connecting pipe.Elastic sealing layer inserts in connecting pipe opening to be connected
When in connect cylinder, both gaps are sealed, avoids the cooling water of high pressure from being flowed out from gap, also can guarantee that the pressure of atomizer
Power.
Switching mechanism includes setting second support on cross bar, rotary setting rotating shaft in second support, and installation is set in rotating shaft
Bar, rotating shaft and the second motor being arranged on cross bar are connected, and mounting rod front end sets connecting cylinder, the second motor and control machine
Structure signal connects.Switching mechanism is that the plane that mounting rod rotates is overlapping with the vertical plane where cross bar, when needing docking, the
Two motor driven axis of rotation so that connecting cylinder routs up the top of cross bar, is docked with connecting pipe；When that need not dock, the
Two motor driven axis of rotation so that connecting cylinder turns back the top of cross bar.
Atomizer is arranged on the opening of cannon spray head, and atomizer is at least four, and atomizer front end sets electrode
Ring, electrode retaining collar electrically connect with the electrostatic generator being arranged on the outside of cannon spray head.Circulation wind-force in cannon spray head, and in the mist of opening
The water smoke for changing shower nozzle ejection can be to fly to transformer by wind-force drive, and atomizer is not set directly in cannon spray head,
So it is that big wind-force carries a small amount of water smoke, ensures the fed distance of water smoke, utilization rate is higher.Electrostatic generator causes electrode retaining collar band
Electricity, such water smoke carry electrostatic, transformer surface can be being directly adsorbed in close to after transformer, without being flowed with gas
Sliding to other places, can improve the utilization rate of water.
Embodiment three
The present embodiment additionally provides a kind of ground transformer spraying cooling method, comprises the following steps：
S1, by contactless infrared temperature sensor the surface temperature of transformer is monitored, transformation is reacted with this
The temperature conditions of device each position；
When S2, the temperature when monitoring somewhither exceed threshold value, atomizing spray mechanism is moved to corresponding transformer temperature by walking mechanism
At connecting pipe of the degree more than the position of threshold value；
S3, atomizing spray mechanism docked with connecting pipe, and open the water pump of water tower so that atomization of the cooling water from spray cylinder
Shower nozzle sprays, and carries electrostatic when ejection, then flies to transformer by wind-force caused by axial flow blower；
During S4, the atomization globule of carrying electrostatic fly to transformer, spray can be improved by the adsorption of transformer
The utilization rate of cooling water；
Temperature declined slowly after S5, spray, opened second solenoid valve so that the ground on cool water shower transformer periphery, increases
Add the humidity on transformer periphery, so as to cool to environment, transformer is cooled indirectly.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
