Technical Field

[0001] The utility model relates to the technical field of zinc oxide lightning arresters, in particular to a zinc oxide lightning arrester which is convenient for fixed installation. Background Art

[0002] Zinc oxide arrester is an arrester with good protection performance. It uses the good nonlinear volt-ampere characteristics of zinc oxide to make the current flowing through the arrester extremely small (microampere or milliampere level) at normal working voltage. When overvoltage acts, the resistance drops sharply, discharging the overvoltage energy to achieve the protection effect. The difference between this arrester and the traditional arrester is that it has no discharge gap, and uses the nonlinear characteristics of zinc oxide to play the role of current discharge and breaking;

[0003] However, most of the existing zinc oxide lightning arresters are installed at high altitudes, so operators need to carry a large amount of installation equipment when performing high-altitude installation, and a large amount of disassembly work is also required when replacing damaged zinc oxide lightning arresters in the later stage. The installation is very troublesome. In order to avoid the above technical problems, it is indeed necessary to provide a zinc oxide lightning arrester that is easy to fix and install to overcome the above defects in the prior art.

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model provides a technical solution, a zinc oxide lightning arrester that is easy to fix and install, including a zinc oxide valve core 1, an outer side of the zinc oxide valve core 1 is sleeved with an umbrella skirt 2, a plurality of umbrella skirts 2 are provided, and the plurality of umbrella skirts 2 are sleeved at the outer side of the zinc oxide valve core 1 at equal distances, the diameter of the zinc oxide valve core 1 is equal to the inner diameter of the umbrella skirt 2, which is convenient for insulation, a stabilizing seat 3 is installed at the bottom end of the zinc oxide valve core 1, a connecting rod 4 is installed at the bottom end of the stabilizing seat 3, a reverse cone 5 is installed at the bottom end of the connecting rod 4, a stabilizing groove plate 6 is sleeved at the bottom end of the stabilizing seat 3, a stabilizing chamber is opened on the inner side of the stabilizing groove plate 6, the diameter of the stabilizing seat 3 is equal to the inner diameter of the stabilizing chamber, the stabilizing seat 3 is slidably connected to the stabilizing groove plate 6 through the stabilizing chamber, which is convenient for quick disassembly of the stabilizing seat 3, and a conical groove plate 7 is welded to the bottom end of the stabilizing groove plate 6;

[0024] A silicone sleeve 8 is bonded to the bottom end of the conical groove plate 7, and a pushing block 9 is movably connected to the inner side of the silicone sleeve 8. A reset spring 10 is spot-welded at the top of the pushing block 9, and a pushing disk 11 is spot-welded at the top of the reset spring 10. An elastic plate 12 is rotatably installed at the top of the pushing disk 11. There are several elastic plates 12, and several of them are installed at the top position of the pushing disk 11 at equal angles. One end of several elastic plates 12 is welded with a fixed gripper 13, which is conducive to fixing the reverse cone 5. A fixed gripper 13 is welded at the top of the elastic plate 12, and a sliding groove 14 is provided on the inner side of the conical groove plate 7.

[0025] A mounting plate 15 is welded to the outer side of the conical groove plate 7, and threaded holes 16 are equidistantly provided on the inner side of the mounting plate 15. A rotation groove 17 is provided at the top of the pushing plate 11 and at the corresponding position of the elastic plate 12. A positioning rod 18 is installed on the inner side of the rotating groove 17. A positioning hole 19 is provided on the inner side of the elastic plate 12 at the corresponding position of the positioning rod 18. The diameter of the positioning rod 18 is equal to the inner diameter of the positioning hole 19. The elastic plate 12 is rotatably connected to the pushing plate 11 through the positioning rod 18, which is beneficial to increase the stability of the fixed reverse cone 5.

[0026] The working principle and use process of the utility model are as follows: first, when the operator needs to preliminarily install the zinc oxide lightning arrester, he can first fix and weld the mounting plate 15 to the top cross bar of the electric pole through the threaded hole 16 on the ground, and then install the cross bar to the top of the electric pole to complete the preliminary installation. Then, when people can bring the zinc oxide lightning arrester to a high altitude, the stabilizing seat 3 can be inserted into the inner position of the stabilizing slot plate 6. At this time, the connecting rod 4 will push the reverse cone 5 into the inner side of the sliding slot 14. At this time, pushing the reverse cone 5 will squeeze open the fixed gripper 13 to push the elastic plate 12 to the inner side of the sliding slot 14, and then the reverse cone 5 will move to the bottom of the fixed gripper 13, at which time the fixed gripper 13 will be stuck in the groove of the reverse cone 5, thereby fixing the reverse cone 5. At this time, the zinc oxide lightning arrester can be fixed. Later, when the model needs to be replaced and the zinc oxide lightning arrester needs to be maintained, it is only necessary to press the push block 9, which will press the reset spring 10, and then push the elastic plate 12 to slide on the inner side of the sliding groove 14 through the push disk 11. At this time, the elastic plate 12 will drive the fixed gripper 13 to slide on the inner side of the sliding groove 14. At this time, the fixed gripper 13 will be moved out from the inner side of the reverse cone 5, and the operator can replace the zinc oxide lightning arrester at this time;

[0027] The push plate 11 is pushed by the push block 9 to make the elastic plate 12 slide on the inner side of the sliding groove 14. At this time, the fixed gripper 13 slides on the inner side of the sliding groove 14, so that the fixed gripper 13 is moved out from the inner side of the reverse cone 5. At this time, the operator can replace the zinc oxide lightning arrester. The new zinc oxide lightning arrester can be directly inserted into the inner side of the stable slot plate 6, so that it can be automatically locked by the reverse cone 5 and the fixed gripper 13. The operation steps are simple and convenient, which can reduce the tools carried for high-altitude operations, improve installation efficiency, further reduce high-altitude operation time, and increase safety.

[0028] Next, when pushing the elastic plate 12, one end of the elastic plate 12 will rotate on the outside of the positioning rod 18 through the positioning hole 19, and the elastic plate 12 will rotate on the inside of the rotating groove 17. At this time, the elastic plate 12 can be prevented from deviating to the side, thereby ensuring the clamping stability of the fixed gripper 13, and the elastic plate 12 can be reused when rotating multiple times, thereby improving the stability of use.

[0029] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
