Abstract
Description
Technical Field
[0001] This utility model relates to the field of portable insulation technology, and in particular to a portable insulation device that can be used for live-line work. Background Technology
[0002] Insulators play a crucial role in power systems and electrical equipment. In power transmission, they support conductors, bear mechanical loads, and prevent current leakage through insulation, ensuring power transmission safety; poor insulation can lead to malfunctions. In electrical equipment, many devices in substations, as well as motors and capacitors, rely on insulation for isolation, such as at transformer bushings and busbars, between motor windings and casings, and between capacitor plates and casings, thus improving equipment reliability. In special environments such as rail transit overhead contact lines and factory electric cranes, they also provide support and insulation, ensuring power supply and equipment operation.
[0003] The insulators currently in use rely on their own sufficient mechanical strength to stably bear the weight of the conductors or conductive parts of electrical equipment and the additional forces generated by environmental factors through reasonable structural design, thereby fixing their spatial position. At the same time, by utilizing high resistivity and good dielectric properties, a high-resistivity barrier is built between the conductors and the towers, ground or other non-conductive parts of electrical equipment. Even under high voltage, sufficient insulation distance can be maintained to prevent air breakdown from forming a conductive channel, avoid short circuits and leakage accidents, and maintain the stability of the power system.
[0004] While the aforementioned insulators have achieved the goal of maintaining the stability of the power system, the high maintenance costs and waste of resources are due to the fact that the entire insulator needs to be replaced when one sheath is damaged. Therefore, a portable insulating device that can be used for live-line work is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a portable insulating device for live-line work, aiming to improve the problem that the existing technology requires the replacement of the entire device when one umbrella cover is damaged, resulting in high maintenance costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A portable insulating device for live-line work includes an insulating column, a connecting column fixedly connected to the side of the insulating column, a fixing component installed inside the connecting column, and a clamping component fixedly connected to the top of the insulating column; the fixing component includes a spring, one end of the spring being fixedly connected to the inside of the connecting column, and the other end of the spring being fixedly connected to a locking block;
[0008] As a further description of the above technical solution:
[0009] The clamping assembly includes a second clamping block, which is fixedly connected to the top of the insulating post. A second threaded post is fixedly connected to the side of the second clamping block, and a threaded rod is threadedly connected to the inside of the second threaded post. A first clamping block is rotatably connected to the outside of the second clamping block, and a first threaded post is fixedly connected to the side of the first clamping block. A threaded rod is threadedly connected to the inside of the first threaded post.
[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:
[0013] The threaded rod has a pin hole inside, and a pin is slidably connected inside the threaded rod.
[0014] As a further description of the above technical solution:
[0015] The threaded rod is internally fixedly connected to a retaining ring, which is specifically made of aluminum.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, when maintaining or replacing the umbrella cover, pulling the insulating column causes the insulating column to detach from the connecting column, allowing the umbrella cover to be removed and replaced separately.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a portable insulating device for live-line work, comprising an insulating column 1, a connecting column 2 fixedly connected to the side of the insulating column 1, a fixing component installed inside the connecting column 2, and a clamping component fixedly connected to the top of the insulating column 1; the fixing component includes a spring 15, one end of the spring 15 fixedly connected to the inside of the connecting column 2, and the other end of the spring 15 fixedly connected to a locking block 14; a locking groove 16 is provided inside the insulating column 1, and the locking groove 16 and the locking block 14 engage with each other. When replacing the umbrella cover 3, by pulling the insulating column 1, the locking block 14 will be moved under force, compressing the spring 15 and causing the spring 15 to contract under force, at which point the umbrella cover 3 on the outer periphery of the insulating column 1 can be removed, so that the damaged umbrella cover 3 can be directly replaced. During installation, the insulating column 1 is moved into the inside of the connecting column 2 and compressed. When it is moved to the designated position, the locking block 14 and the locking groove 16 engage with each other under the tension of the spring 15's return, thus fixing it. The operation is convenient, greatly reducing the cost of maintaining the umbrella cover 3 while saving resources.
[0033] Reference Figure 1 and Figure 3 The clamping assembly includes a second clamping block 7, which is fixedly connected to the top of the insulating post 1. A second threaded post 9 is fixedly connected to the side of the second clamping block 7, and a threaded rod 10 is threadedly connected inside the second threaded post 9. A first clamping block 6 is rotatably connected to the outside of the second clamping block 7, and a first threaded post 8 is fixedly connected to the side of the first clamping block 6. The threaded rod 10 is threadedly connected inside the first threaded post 8. By rotating the threaded rod 10, the first clamping block 6 can be rotated on the side of the second clamping block 7 via the threaded post 8, thereby clamping and fixing the wire. Supported by the insulating post 1, the wire is prevented from falling and the structural integrity of the power transmission line is ensured. The threaded rod 10 has a pin hole 11 inside, and a pin 12 is slidably connected inside the threaded rod 10. By inserting the pin 12 into the pin hole 11, the threaded rod 10 will not detach from the threaded post 8, thus improving the effectiveness of the device. A fixing ring 13 is fixedly connected inside the threaded rod 10. The fixing ring 13 is made of aluminum. When supporting the wire, the operator can use a tool at a distance to rotate the threaded rod 10 with the help of the fixing ring 13 to clamp the wire. This eliminates the need for the operator to frequently climb to the designated position to work, thus making the work more convenient.
[0034] Reference Figure 1 and Figure 2The outer periphery of the insulating column 1 is equipped with umbrella sleeves 3. Multiple umbrella sleeves 3 are set, and multiple umbrella sleeves 3 are connected in series to form an insulator string, which can increase the overall insulation length. A sufficient number of silicone insulators can effectively prevent current leakage and avoid flashover. As the voltage level increases, a larger insulation distance is required to withstand high voltage. The combination of multiple insulators can provide the insulation path required to ensure the safe and stable operation of the transmission line. The bottom of the insulating column 1 is fixedly connected to the base 4, and the outer periphery of the base 4 is threaded with nuts 5, which makes it convenient for workers to fix the insulators. Clamping blocks 1 6 and 2 7 are made of aluminum, which has good corrosion resistance and can ensure good performance for long-term outdoor use. The umbrella sleeves 3 are made of silicone, which has high resistivity and can effectively prevent current from passing through.
[0035] Working principle: First, when maintaining or replacing the umbrella cover 3, pulling the insulating column 1 will cause the locking block 14 to move under force, compressing the spring 15 and causing it to contract. At this time, the umbrella cover 3 can be removed through the insulating column 1, allowing for direct replacement of the damaged umbrella cover 3. During installation, the insulating column 1 is moved into the connecting column 2. When it reaches the designated position, the locking block 14 and the locking groove 16 will engage and fix it under the tension of the spring 15's return. This operation is convenient and greatly reduces the cost of maintaining the device. Second, when it is necessary to support the wire, the operator can connect the tool to the fixing ring 13, which will drive the threaded rod 10 to rotate. At this time, under the action of the threaded column 8, the clamping block 6 will flip on the side of the clamping block 7, thereby clamping and fixing the wire. The insulating column 1 supports the wire, so the operator does not need to climb to a specific height to operate, reducing labor intensity and improving work efficiency.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
