firstly, a positioning screw can be arranged in the threaded hole 101 at the proper position of the connecting piece 1, then the device is installed, and then the power transmission line 30 directly passes through the wire clamping groove 501 of the wire clamping block 5, so that the operation is simple and the efficiency is higher.
During in-service use, when outside fan is great, power transmission line 30 can be blown to wind-force, and at this moment, because the internal surface subsides of fastener groove 501 are equipped with cushion 6, cushion 6 has certain flexible elasticity, can provide the buffering to power transmission line 30 slight rocking, avoids strong wind direct action to the power transmission line 30 of fixed state and leads to power transmission line 30 to appear hard the damage.
In addition, the wind power can also blow the wind power blade 10, so that the wind power blade 10 drives the rotating rod 8 to rotate, on one hand, the poking piece 12 on the rotating rod 8 can rotate along with the rotating rod, the poking piece 12 is arranged in the operating box 7, the rotating poking piece 12 can continuously contact with the elastic piece 13 in the operating box 7 and can smoothly pass through the elastic piece 13 after the elastic piece 13 is deformed, and therefore, the wind power is consumed, and moreover, a plurality of elastic balls 14 are arranged in the inner cavity of the hollow energy consumption box 11, and the elastic balls 14 can be continuously poked by the poking piece 12 in the rotating process, so that the elastic balls 14 at the position play a further energy consumption role, and the wind power consumption and the speed reduction of the two sides of the composite insulator 3 are effectively carried out; on the other hand, the rotating rod 8 will drive the cam 15 to continuously rotate, so that the cam 15 intermittently presses down the first piston plate 17, when the first piston plate 17 moves down, the pressing rod 21 at the bottom thereof may puncture the water bag type adhesive liquid ball 23, so that the adhesive liquid therein flows out, the flowing adhesive liquid will dissolve in the adhesive liquid solvent 22, so that the concentration of the adhesive liquid in the adhesive liquid solvent 22 continuously increases, after long-term use, if the elastic pad 6 becomes thinner and damaged due to multiple collisions, the valve 29 may be opened, so that the adhesive liquid may flow out from the hollow flexible conduit 28, so as to complement the elastic pad 6, or effectively bond the elastic pad 6 and the power transmission line 30; in addition, arc push pedal 27 pastes the side of establishing at cushion 6, along with first piston plate 17 is pushed down, the arc push pedal 27 of the other end can be intermittently extrudeed cushion 6, and then intermittently carry out a lot of brakings to power transmission line 30 in cushion 6 inner circle, both can release the energy fast through rocking of power transmission line 30, can make power transmission line 30 get off fast again, it is safer to use, it is noted that, along with the increase of duration of strong wind, the water pocket formula that is punctured bonding liquid ball 23 can increase gradually, therefore make the bonding liquid concentration in bonding liquid solvent 22 also rise gradually, the benefit that sets up like this lies in: when the duration of strong wind is gradually increased, the power transmission line 30 shakes more frequently, and the loss of the elastic cushion 6 is faster, so that the number of the water bag type bonding liquid balls 23 is increased adaptively, the bonding liquid in a dissolved state has enough concentration to complement the elastic cushion 6, or the bonding liquid and the power transmission line 30 are effectively bonded, the using effect is better, and the adaptability is stronger.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
