One end of the line X1 is connected with a power supply, and the other end is manually plugged into the first L-shaped junction block 105d-6 through the plug interface by a worker. One end of the line X2 is connected to the microwave generating device 104, and the other end is fixedly connected to the second L-shaped junction block 105 d-7. The lock-in assembly 105 is provided with a port in the middle to facilitate entry and exit of the screw post 105b-2 and communicates with the screw port M. The spiral column 105b-2 is located at the center of the sleeve ring 105c-2, and in order to ensure the stability of rotation, the arc-shaped deflection groove 105c-3 and the toggle piece 105b-6 can be symmetrically arranged into two groups.
Preferably, the microwave generating device 104 and the power supply can be implemented by the prior art, and are not described in detail. The existing microwave generating device 104 is installed, stopping is not needed, microwaves are used for heating the fan blades, so that the fan blades can keep a certain temperature in work, and the microwaves can also heat the rainwater when the rainwater is attached to the fan blades, the temperature of the water on the surfaces of the blades can also rise after the water absorbs the microwave energy, so that the purpose of preventing freezing is achieved, the rainwater is prevented from freezing on the fan blades, and the rainwater is separated from the fan blades along with the swinging of the fan blades.
When the microwave locking device is used, a worker needs to manually plug one end of the line X1 into the first L-shaped junction block 105d-6 through the plug interface for preliminary connection, and the microwave generating device 104 and the locking connection component 105 are placed into the accommodating cavity 103a through the anti-rotation limiting groove 103 b. Only by rotating the tightening head 105b-1, as the locking connection component 105 is limited by the anti-rotation limiting groove 103b, the first thread 105b-3 on the threaded column 105b-2 can be screwed into the threaded fixing sleeve 105b, and meanwhile, the second thread 105b-4 at the bottom end of the threaded column 105b-2 rotates downwards and is screwed into the threaded opening M of the threaded fixing block 103c, so that the upper half part of the threaded column 105b-2 is fixed with the locking connection component 105, and the lower half part of the threaded column 105b-2 is fixed with the fixing plate component 103, and finally, the integral fixation between the microwave generating device 104 and the locking connection component 105 and the fixing plate component 103 is realized, and the microwave generating device 104 is prevented from loosening and separating during the operation of the fan blades and is prevented from being damaged due to the impact in the blades. In the process, the threaded column 105b-2 is in a spiral descending trend, a certain distance is reserved between the shifting piece 105b-6 in the middle of the threaded column 105b-2 and the arc deflection groove 105c-3 at the bottom, when the second thread 105b-4 is screwed into the thread opening M, the shifting piece 105b-6 can be screwed into the arc deflection groove 105c-3, when the shifting piece 105b-6 reaches the tail end of the arc deflection groove 105c-3, the threaded column 105b-2 continues to rotate downwards, the shifting piece 105b-6 extrudes the second spring 105b-7 to move upwards relative to the lifting groove 105b-5, and drives the overlapped fan blade assembly 105c-c to rotate integrally.
Referring to fig. 9, when the overlapped blade disk 105c-1 rotates, the transverse conductive piece 105c and the L-shaped conductive piece 105d move outward simultaneously, so that the distance between the two connection terminals 105g is reduced, and finally the two sets of connection terminals 105g are connected in contact. When the transverse conductive piece 105c is moved outward, one side thereof is finally brought into contact with the second L-shaped terminal piece 105d-7, so that the wiring X2 is communicated with the transverse conductive piece 105 c. When the L-shaped conductive block 105d moves outward, the moving conductive block 105h on one side moves along with it, the lifting inclined plane 105i on the moving conductive block 105h lifts the position of the roller 105d-1 contacting with it along the lifting inclined plane 105i, due to the action of the hinge post 105d-3 in the middle of the pressing frame 105d-2, the end where the inclined arc-shaped head 105d-4 is located will be gradually inclined, the end of the inclined arc-shaped head 105d-4 presses the line X1, the line X1 is tightly contacted and fixed with the first L-shaped wiring block 105d-6, and the line X1 is prevented from falling off by the arc-shaped non-return layer 105d-5 attached to the line X1, so as to ensure the stability of the device, at this time, the conducting groove 105j is engaged with the first L-shaped wiring block 105d-6, and finally the microwave generating device 104 is locked with the conducting assembly 105 through the line X2, and line X1 is connected to a power source, the microwave generating device 104 begins to operate.
When disassembly is required, the tightening head 105b-1 is rotated reversely, and the L-shaped conductive block 105d and the transverse conductive block 105c move to the middle under the action of the telescopic column 105e and the first spring 105f, which is a reverse process of the above process, and finally, the fixing of the line X1 is released, the fixing of the whole device is released, and the circuit connection is disconnected.
In the whole process, the start and stop of the microwave generating device 104 can be controlled only by workers through the forward rotation and reverse rotation tightening heads 105b-1, the resource waste is reduced, the utilization rate is improved, the power supply connected with the line X1 can be quickly fixed and disassembled, the efficiency in power supply replacement is convenient to improve, the maintenance time is saved, the disassembly speed of the microwave generating device 104 is ensured at the same time through the quick fixing and unlocking of the whole connection between the microwave generating device 104 and the fixing plate assembly 103, and the economic loss is reduced in emergency maintenance. Thus, only the forward and reverse rotation of the tightening head 105b-1 is required to control the start and stop of the microwave generating device, the overall installation of the microwave generating device 104, and the quick connection of the power line X1.
To sum up, through adopting at the inside microwave generating device that arranges of fan blade, can not shut down the condition at the unit, real-time production microwave energy to fan blade surface rainwater heating prevents to form the icing on the blade surface to reach fan blade and prevent freezing and icing. And then from the technological change of fan blade deicing to preventing icing, promote the fan and prevent the effect of congealing, avoid congealing the harmful effects that the unit that brings is exerted oneself and is reduced, the generator reduces.
