Embodiment Construction
[0016] In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, a kind of crankshaft rotation type power transmission line anti-bird thorn of the present invention comprises a connecting frame, a shaft sleeve 1, a crankshaft and a needle 2, and the connecting frame includes a bottom plate 4 having a connecting hole 3 and two sides vertically fixed on the bottom plate 4. The vertical support 5 at the end, the top of the vertical support 5 has a support hole. In the connecting hole 3 of the connecting frame, bolts are loaded into and the assembled crankshaft rotating transmission line anti-bird thorn can be fixed on the transmission tower.
[0018] Such as image 3 , 4 As shown, the two ends of the crankshaft are connecting ends, and two adjacent crankshafts are connected by the cranksha...

The invention relates to a crankshaft rotary type bird-prevention thorn for an electric transmission line. The crankshaft rotary type bird-prevention thorn for the electric transmission line overcomes the defects that a traditional umbrella-shaped bird-prevention thorn cracks easily in the installation process, and the coverage area has blind corners easily. The crankshaft rotary type bird-prevention thorn for the electric transmission line comprises a connecting frame, shaft sleeves, crankshafts and thorn needles, wherein the connecting frame comprises a base plate with connecting holes and vertical supports vertically fixed to the two ends of the base plate, a supporting hole is formed in the top of each vertical support, two adjacent crankshafts are connected through a crankshaft connecting plate, the two ends of each crankshaft connecting plate are respectively provided with a threaded hole connected with a crankshaft connecting end, external connecting ends of two end crankshafts at the two sides are connected inside the supporting holes of the vertical supports through bolts, the thorn needles are evenly fixed on the surface of each shaft sleeve in a radial shape, and the crankshafts are installed in the shaft sleeves respectively. The crankshaft rotary type bird-prevention thorn for the electric transmission line is connected with the multiple crankshafts through crankshaft connecting plates, each crankshaft is provided with the corresponding shaft sleeve through the thorn needles, and therefore the coverage area of the bird-prevention thorn device is enlarged. The crankshaft rotary type bird-prevention thorn for the electric transmission line is simple in structure, easy to implement, high in universality and capable of meeting the requirement for preventing bird trouble faults of the electric transmission line.
Description
technical field [0001] The invention relates to an anti-bird damage device for transmission lines, in particular to an anti-bird thorn device for transmission line poles and towers. Background technique [0002] The tripping fault of transmission lines caused by bird damage is about 15% every year. In order to prevent the occurrence of bird damage, people have invented a series of anti-bird products, which have played a positive role in reducing bird damage. For example, a utility model patent with the notification number CN203463904U discloses a high-voltage power tower anti-bird thorn device, which belongs to the traditional umbrella-shaped anti-bird thorn device. Birds and cause bird damage faults. Contents of the invention [0003] The technical solution to be solved by the present invention is to provide a crank-rotating type transmission line anti-bird thorn, which overcomes the defects that the traditional umbrella-shaped anti-bird thorn is prone to gaps during ins...
