[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0019] Embodiment 1:

[0020] As Figs. 1-3 The utility model discloses a lightning protection structure for power transmission line, including mounting seat 1 and the multiple lightning rod 2 of being established on mounting seat 1, the multiple lightning rod 2 top all cover the protection cap 3 for temporarily isolating lightning rod 2 sharp end with external environment, the sponge layer is glued to the inner ring of protection cap 3, and the sharp end of lightning rod 2 is protected, and the mounting piece for fixing protection cap 3 is established on the pole body of lightning rod 2. The mounting piece includes the two mounting rods 4 that are mirror image symmetry and are established at the bottom edge of protection cap 3, and the bottom of mounting rod 4 is all fixed with the positioning ring block 5 for holding the pole body of lightning rod 2, and the bottom of positioning ring block 5 is all fixed with the connecting ring plate 6, and the continuous outer thread groove is opened to the two connecting ring plates 6, and the threaded sleeve 7 for holding connecting ring plate 6 is connected with outside thread, and the sharp end of lightning rod 2 is shielded by the cooperation of protection cap 3 and mounting piece when installing the lightning arrester, both avoid the impact damage that outside can cause lightning rod 2 when installing, reduce the sharp end of lightning rod 2 security risk to the installation worker, and the parts in protection cap 3 and mounting piece all adopt plastic material and make, and quality is light and will not cause lightning rod 2 deformation.

[0021] Embodiment 2:

[0022] The technical scheme is basically same with the first embodiment, the difference is that, as shown in the figure, one of the positioning ring blocks 5 is provided with a butt joint block 8 at the butt joint end, and the other positioning ring block 5 is provided with a butt joint groove matched with the butt joint block 8 at the butt joint end, so that the two connecting ring plates 6 are butt jointed to form a continuous external thread for positioning, avoiding the discontinuous external thread to hinder the screwing of the thread sleeve 7.
