Description

Technical Field

[0001] The utility model relates to the field of pole switch installation isolation devices, in particular to a live pole switch installation isolation device. Background Art

[0002] A pole-mounted switch refers to a type of safety switch used on utility poles to ensure the safety of electricity use. Its main function is to isolate the high voltage of the circuit. It generally uses a spring operating mechanism and can perform electric and manual opening and closing operations. Since the connectors of the pole-mounted switch are directly exposed to the air, if there are conductive debris or animals such as birds, squirrels, and mice between the connectors, it will cause a short circuit. Since the conductive circuit is high voltage, there will be greater safety risks during use. Utility Model Content

[0003] The main purpose of the utility model is to provide a live installation isolation device for a pole-mounted switch, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a live installation isolation device for a pole-mounted switch comprises two isolation plates, and an assembly component is installed on the surfaces of the two isolation plates for installing and connecting the two isolation plates and adjusting the distance between the two isolation plates, and semi-annular clamping rings are fixedly installed on opposite sides of the two isolation plates, and the clamping rings are fixed to the surfaces of the isolation plates by connecting rods, and the number of the clamping rings is set to be multiple.

[0005] The top and bottom of the clamping ring are both provided with grooves, a plurality of connecting springs are fixedly installed inside the grooves, an arc plate is movably installed inside the grooves, and one end of the connecting spring is fixed on the surface of the arc plate.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the pole-mounted switch live installation isolation device includes two isolation plates 1, and the surfaces of the isolation plates 1 are provided with multiple holes for heat dissipation. The isolation plates 1 are located on both sides of the middle joint to isolate adjacent joints. Assembly components are installed on the surfaces of the two isolation plates 1 for installing and connecting the two isolation plates 1 and adjusting the distance between the two isolation plates 1. Semi-annular clamping rings 2 are fixedly installed on opposite sides of the two isolation plates 1. The clamping rings 2 are clamped on the column of the joint to prevent the isolation plates 1 from falling off. The clamping rings 2 are fixed to the surfaces of the isolation plates 1 by connecting rods 3. The number of the clamping rings 2 is multiple.

[0020] When installing the isolation plates 1, directly place the two isolation plates 1 on both sides of the joint, then move the two isolation plates 1 toward each other so that the clamping ring 2 is clamped on the column of the joint, and then use the assembly components to connect and fix the two isolation plates 1. The isolation plates 1 can avoid the possibility of short circuit of adjacent joints as much as possible to ensure safe use. At this time, the clamping ring 2 can ensure the stable installation of the isolation plates 1, and the assembly components can prevent the two isolation plates 1 from spreading out.

[0021] The top and bottom of the clamping ring 2 are provided with grooves 4, and the grooves 4 are arc-shaped. A plurality of connecting springs 5 ​​are fixedly installed inside the groove 4, and the connecting springs 5 ​​are equidistantly arranged. An arc-shaped plate 6 is movably installed inside the groove 4, and one end of the connecting spring 5 is fixed to the surface of the arc-shaped plate 6. When the clamping ring 2 is installed, since the length of the column of the joint is not fixed (the shape of the column is bamboo-shaped), the arc-shaped plate 6 needs to be squeezed into the inside of the groove 4 first during installation. At this time, the connecting spring 5 is in a compressed state. After the clamping ring 2 is installed, due to the rebound effect of the connecting spring 5, the arc-shaped plate 6 will rest against the surface of the column, thereby ensuring that the isolation plate 1 is installed firmly.

[0022] The assembly component includes a mounting rod 7, on the surface of which an internal threaded sleeve 8 is movably mounted, the mounting rod 7 is fixed to the surface of one of the isolation plates 1, and on the surface of the other isolation plate 1 a threaded rod 9 is fixedly mounted, the internal threaded sleeve 8 is threadedly sleeved on the surface of the threaded rod 9, a guide ring 10 is fixedly mounted on the surface of the mounting rod 7, an annular groove 11 is provided on the inner side of the internal threaded sleeve 8, and the guide ring 10 is movably mounted inside the annular groove 11.

[0023] Align the threaded rod 9 with the inside of the internal threaded sleeve 8 and rotate the internal threaded sleeve 8, the threaded rod 9 will move closer to the other isolation plate 1. Since the connection is through threads, when the isolation plates 1 are disassembled, it is difficult to disassemble the two isolation plates 1 by simple lateral and longitudinal external forces, thereby ensuring the stability of the installation. At the same time, there is no need to use external structure for locking, and the structure is simple and convenient.

[0024] A guide rod 12 is fixedly installed on the surface of one of the isolation plates 1, and a guide tube 13 is fixedly installed on the surface of the other isolation plate 1. The guide rod 12 is movably installed inside the guide tube 13. The guide rod 12 moves inside the guide tube 13, which can prevent the two isolation plates 1 from moving and offsetting. At the same time, after the isolation plate 1 is installed, the isolation plate 1 itself is difficult to rotate.

[0025] The assembly component is installed in the middle of the isolation plate 1. The guide rods 12 and guide tubes 13 are provided in two groups and are arranged in symmetrical positions of the assembly component to ensure the force balance of the isolation plate 1 after installation.

[0026] It should be noted that the utility model is an isolation device for live installation of a pole-mounted switch. When in use, two isolation plates 1 are directly placed on both sides of the joint, the threaded rod 9 is aligned with the inside of the internal threaded sleeve 8, and the internal threaded sleeve 8 is rotated. The threaded rod 9 will move close to the other isolation plate 1, and the guide rod 12 moves inside the guide tube 13 to squeeze the arc plate 6 into the inside of the groove 4. At this time, the connecting spring 5 is in a compressed state. After the retaining ring 2 is installed, due to the rebound effect of the connecting spring 5, the arc plate 6 will rest on the surface of the column, ensuring that the isolation plate 1 is installed firmly. The isolation plate 1 can avoid the possibility of short circuit between adjacent joints as much as possible, thereby ensuring safe use.
