When the strong wind blows on the on-line monitoring device for grounding wires, the monitoring device is subjected to a large impact force, and the monitoring device is easily damaged, thus affecting the normal use of the monitoring device. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model proposes an on-line monitoring device for grounding wires used in power dispatching. The main body of the monitoring device will rotate around the connecting ball due to the impact force of the wind, removing the impact force from the wind received by the main body of the monitoring device, and avoiding the situation that the main body of the monitoring device is damaged and cannot be used normally.

[0006] The technical solution for achieving the purpose of the present utility model is as follows: An on-line monitoring device for grounding wires used in power dispatching includes a monitoring device body. A fixed seat is provided at the bottom of the monitoring device body. A fixed rod is fixedly installed on the top wall surface of the fixed seat. A support rod is provided at the top of the fixed rod. The monitoring device body is fixedly installed on the top of the support rod. A connecting ball is fixedly installed on the top wall surface of the fixed rod. A connecting groove is formed on the bottom wall surface of the support rod.

[0013] Second: In the present utility model, by driving the reset screw to rotate by the output shaft of the reset motor, since the reset disc is slidably installed inside the limit groove through the limit block, the reset disc moves downward with the rotation of the reset screw under the limitation of the limit groove and the limit block. As a result, the reset spring is pulled and extended, improving the elasticity of the reset spring, enabling the positioning disc to straighten the connecting rope, and ensuring the stable position of the support rod.

Detailed Embodiment

[0020] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides an on-line monitoring device for grounding wires used in power dispatching by making improvements herein. The technical solution of the present utility model is:

[0022] As Figure 1 - Figure 2As shown in the figure, an on-line monitoring device for grounding wires used in power dispatching includes a monitoring device body 1. A fixing base 2 is provided at the bottom of the monitoring device body 1. The fixing base 2 is fixed to the ground by bolts. A fixing rod 3 is fixedly installed on the top wall surface of the fixing base 2. A support rod 4 is provided at the top of the fixing rod 3. The monitoring device body 1 is fixedly installed at the top of the support rod 4. A connecting ball 7 is fixedly installed on the top wall surface of the fixing rod 3. A connecting groove 5 is opened on the bottom wall surface of the support rod 4. A rotating groove 6 is opened on the inner side wall of the connecting groove 5. The connecting ball 7 is rotatably installed inside the rotating groove 6. A reset disk 10 is slidably installed inside the fixing rod 3. A limiting groove 11 is opened on the inner side wall of the fixing rod 3. A limiting block 12 is fixedly installed on the side wall of the reset disk 10. The limiting block 12 is slidably installed inside the limiting groove 11. A reset spring 13 is fixedly connected to the top wall surface of the reset disk 10. The top end of the reset spring 13 is fixedly connected to a positioning disk 8. A connecting rope 9 is fixedly connected to the top wall surface of the positioning disk 8. The connecting rope 9 passes through the inside of the connecting ball 7 and is fixedly installed on the inner top of the connecting groove 5; by using the elasticity of the reset spring 13 to pull the positioning disk 8 downward, the positioning disk 8 straightens the connecting rope 9. The support rod 4 rotates around the connecting ball 7 under the pulling of the connecting rope 9, so that the support rod 4 and the fixing rod 3 are on the same horizontal line. By movably installing the support rod 4 on the side wall of the connecting ball 7, when the wind blows on the side wall of the monitoring device body 1, the monitoring device body 1 will rotate around the connecting ball 7 due to the impact force of the wind, removing the impact force of the wind received by the monitoring device body 1 and preventing the monitoring device body 1 from being damaged, thus affecting the normal use of the monitoring device body 1.

[0023] As Figure 2 shown, in an embodiment, in order to ensure that the positioning disk 8 can straighten the connecting rope 9, a reset motor 14 is provided on the inner bottom wall surface of the fixing rod 3. The output shaft of the reset motor 14 is fixedly installed with a reset screw 15. The reset disk 10 is threadedly installed on the side wall of the reset screw 15; by using the output shaft of the reset motor 14 to drive the reset screw 15 to rotate, since the reset disk 10 is slidably installed inside the limiting groove 11 through the limiting block 12, the reset disk 10 moves downward along with the rotation of the reset screw 15 under the limitation of the limiting groove 11 and the limiting block 12. Therefore, the reset spring 13 is stretched, improving the elasticity of the reset spring 13, enabling the positioning disk 8 to straighten the connecting rope 9 and ensuring the stable position of the support rod 4.

[0024] As Figure 2 - Figure 3As shown, in one embodiment, in order to further ensure the stable position of the support rod 4, a positioning groove 19 is formed in the inner side wall of the rotation groove 6, and a plurality of positioning balls 18 are rotatably installed on the side wall of the connecting ball 7. The positioning balls 18 are rotatably installed inside the positioning groove 19. By rotatably installing the positioning balls 18 inside the positioning groove 19, the position of the support rod 4 is limited, thereby ensuring the stable position of the support rod 4 and avoiding the situation where the monitoring device body 1 tilts with the wind when the wind is relatively small. A receiving groove 16 is formed in the inner side wall of the connecting ball 7, and an extension spring 17 is fixedly connected to the inner side wall of the receiving groove 16. The outer end of the extension spring 17 near the outside is sleeved on the side wall of the positioning ball 18. By using the side wall of the extension spring 17 to support the positioning ball 18, the positioning ball 18 moves outwards, so that the positioning ball 18 can be more stably stuck inside the positioning groove 19. When the external wind is relatively large and blows on the side wall of the monitoring device body 1, the positioning ball 18 retracts into the inside of the extension spring 17 under the push of the inner side wall of the support rod 4, enabling the support rod 4 to tilt with the wind.

[0025] The specific working method is as follows: Electrically connect the monitoring device body 1 with an external ground wire. By using the elasticity of the return spring 13 to pull the positioning disk 8 downward, the positioning disk 8 straightens the connecting rope 9. The support rod 4 rotates around the connecting ball 7 under the pull of the connecting rope 9, so that the support rod 4 and the fixed rod 3 are on the same horizontal line. By movably installing the support rod 4 on the side wall of the connecting ball 7, when the wind blows on the side wall of the monitoring device body 1, the monitoring device body 1 will rotate around the connecting ball 7 due to the impact force of the wind, removing the impact force of the wind received by the monitoring device body 1 and preventing the monitoring device body 1 from being damaged, thereby affecting the normal use of the monitoring device body 1. By rotatably installing the positioning balls 18 inside the positioning groove 19, the position of the support rod 4 is limited, thereby ensuring the stable position of the support rod 4 and avoiding the situation where the monitoring device body 1 tilts with the wind when the wind is relatively small. By using the side wall of the extension spring 17 to support the positioning ball 18, the positioning ball 18 moves outwards, so that the positioning ball 18 can be more stably stuck inside the positioning groove 19. When the external wind is relatively large and blows on the side wall of the monitoring device body 1, the positioning ball 18 retracts into the inside of the extension spring 17 under the push of the inner side wall of the support rod 4, enabling the support rod 4 to tilt with the wind.

[0026] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed by the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present invention belong to the common general knowledge of those skilled in the art.
