Description

Technical Field

[0001] This application relates to the field of insulating tool technology, and more particularly to an insulating structure. Background Technology

[0002] In power systems, insulating operating rods are typically used to operate high-voltage disconnect switches (knife switches) to cut off or close circuits.

[0003] However, in practical applications, due to long-term heat generation between the contacts of the disconnector, poor corrosion resistance, and inadequate daily maintenance, the disconnector often becomes difficult to operate.

[0004] At this point, the operator needs to use considerable force to forcibly pull the switch. However, it is inconvenient to apply force with the insulated operating rod when pulling the switch. Sometimes, the operator even needs to be lifted off the ground to generate the force required to pull the switch, which poses a significant safety hazard. Utility Model Content

[0005] This application provides an insulating structure to solve the problem of inconvenience in applying force when pulling the switch using existing insulating operating rods.

[0006] This application provides an insulating structure, including:

[0007] Insulating rod body;

[0008] A sliding impact cylinder is slidably sleeved outside the insulating rod body;

[0009] Two first clamping parts are provided, the sliding impact cylinder is located between the two first clamping parts, and the distance between the two first clamping parts is greater than the length of the sliding impact cylinder;

[0010] Two second clamping parts are provided, which are disposed opposite to the first clamping part, and the first clamping part and the second clamping part are connected in a one-to-one correspondence, so that the second clamping part and the first clamping part are respectively clamped on the insulating rod body from both sides;

[0011] The sliding impact cylinder is configured such that, when driven by an external force to move along the insulating rod, its end impacts at least one of the first clamping portion and the second clamping portion located on the same side of the sliding impact cylinder, thereby driving the insulating rod to move.

[0012] In one possible implementation, an insulating pad is also included, which is in contact with the surface of the insulating rod. The sliding impact cylinder is slidably sleeved outside the insulating pad, and the first clamping part and the second clamping part are clamped on the side of the insulating pad away from the insulating rod.

[0013] In one possible implementation, the insulating pad includes a first pad and a second pad disposed opposite to each other, both of which are configured to be arc-shaped.

[0014] In one possible implementation, both ends of the first pad and the second pad are provided with positioning protrusions, and the ends of the first clamping part and the second clamping part away from the sliding impact cylinder abut against the positioning protrusions.

[0015] In one possible implementation, both the first clamping part and the second clamping part are arc-shaped clamps, and the two ends of the arc-shaped clamps are provided with connecting ears, and the connecting ears of the first clamping part and the second clamping part are connected by bolts.

[0016] In one possible implementation, the connecting lug extends to the outside of the sliding impact cylinder to contact the end of the sliding impact cylinder.

[0017] In one possible implementation, the thickness of the connecting ear is greater than or equal to 4 mm.

[0018] In one possible implementation, the sliding impact cylinder is a metal cylinder.

[0019] In one possible implementation, the wall thickness of the sliding impact cylinder is greater than or equal to 8 mm.

[0020] In one possible implementation, a tool head is also included, which is disposed at both ends of the insulating rod body, along with the sliding impact cylinder.

[0021] The insulation structure provided in this application includes a sliding impact cylinder with a first clamping part and a second clamping part at each end. The first and second clamping parts at the same end of the sliding impact cylinder are interconnected and clamped onto the insulating rod of the insulation structure for positioning. The sliding impact cylinder is fitted onto the insulating rod at a location easily accessible to the user and can slide along the insulating rod under external force. When a larger force is needed to pull the switch downwards, one end of the insulating rod is connected to the switch, and the sliding impact cylinder can be pulled by hand or with a tool, causing it to strike at least one of the first or second clamping parts located below it, thus moving the insulating rod and the switch downwards. When a larger force is needed to push the switch upwards... When moving, the sliding impact cylinder is pulled by hand or with the aid of tools, causing it to strike at least one of the first clamping part and the second clamping part located above it. This causes the insulating rod to move the switch upwards. Compared to the traditional method of manually pulling the insulating rod for a long time, the sliding impact cylinder can apply a greater force to the insulating rod in a short time by sliding back and forth to strike at least one of the first clamping part and the second clamping part at the same end. This reduces the initial force required to overcome static friction, and the energy of the sliding impact cylinder's movement is converted into instantaneous kinetic energy, which also helps to overcome inertia. This reduces the physical exertion of the user, lowers the intensity of manual operation, reduces the difficulty of opening and closing the switch, and helps to improve the safety of opening and closing the switch.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0041] First, let me explain the terms used in this application:

[0042] Disconnect switch: A common name for a high-voltage disconnect switch, it is a switching device used in power systems. It is mainly used to control the opening and closing of circuits through mechanical operation. It is usually used in high-voltage power systems to ensure safe and reliable power transmission.

[0043] Insulated operating rod: This is a safety tool used in power systems. It is mainly used when operating high-voltage electrical equipment to ensure that operators maintain a safe distance from live equipment, thereby preventing electric shock accidents.

[0044] In power systems, insulated operating rods are commonly used to operate high-voltage disconnect switches. However, in actual operation, due to factors such as prolonged overheating of the disconnector contacts, poor corrosion resistance, and inadequate daily maintenance, situations often arise where the disconnector cannot be opened or closed properly.

[0045] Currently, when operators encounter situations where the knife switch is difficult to open or cannot be closed properly, they usually have to rely on manual operation. Sometimes, it even requires lifting the entire person off the ground to pull down the knife switch. This method is not only inefficient but also poses safety hazards.

[0046] In response to this, this application provides an insulating structure that allows for the movement of a sliding impact cylinder by hand or with the aid of a tool when the disconnect switch is difficult to open or close. This impacts the cylinder against at least one of the first and second clamping parts located above or below the cylinder, providing an impact force that is transmitted to the insulating rod. This force causes the insulating rod to move the disconnect switch, assisting in opening or closing the disconnect switch. This effectively solves the problem of disconnect switches being too tight in the prior art, which makes them difficult to open or close. It also helps improve the work efficiency of operators and reduces power outage time for users, thereby improving power supply reliability.

[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of the insulation structure provided in the embodiments of this application; Figure 2 An exploded view of the insulation structure provided in the embodiments of this application.

[0049] In some embodiments, see Figure 1 and Figure 2 As shown, the insulation structure includes an insulating rod 100, which is typically made of high-strength insulating materials such as fiberglass or epoxy resin. These materials have excellent electrical insulation properties and mechanical strength, and can withstand certain bending and tensile forces.

[0050] The two ends of the insulating rod 100 can be equipped with connectors to connect tool heads or other rods to extend the length of the insulating rod 100 and adapt to the usage requirements in different scenarios. The connectors can be threaded connectors made of metal materials or other structures that facilitate connection. As long as the stability and safety of the connection with other components can be guaranteed and the corrosion resistance can be certain, the usage requirements can be met. This embodiment does not limit it.

[0051] Insulating structures are not limited to operating knife switches; they can also serve different functions depending on the specific application. Therefore, the tool heads for insulating structures are generally of various types, such as hooks, clamps, and scissors, and different tool heads can be used depending on the specific needs of the insulating structure.

[0052] A handle can also be provided on the insulating rod 100. The handle mainly serves to prevent slipping and make it easy for users to grip. At the same time, the surface of the handle can be covered with a layer of insulating material to improve the safety of the insulating structure.

[0053] An assisting device is also provided on the insulating rod 100. The assisting device is located at the end of the insulating rod 100 away from the tool head. The assisting device can apply pulling or pushing force to the insulating rod 100, making it more convenient for the operator to apply force to the insulating rod 100, which helps to improve the convenience and safety of using the insulating structure.

[0054] The following examples illustrate the structure of the assistive device.

[0055] Figure 1 This is a schematic diagram of the insulation structure provided in the embodiments of this application; Figure 2 Exploded view of the insulation structure provided in the embodiments of this application; Figure 3 This is a partial structural diagram of the insulation structure provided in an embodiment of this application.

[0056] For some possible implementations, please refer to Figure 2 and Figure 3 As shown, the assist device with the insulating structure includes a sliding impact cylinder 200, a first clamping part 300, and a second clamping part 400.

[0057] The sliding impact cylinder 200 is sleeved on the outside of the insulating rod 100 and can move along the insulating rod 100. There are two of each of the first clamping part 300 and the second clamping part 400. There is one first clamping part 300 and one second clamping part 400 at each end of the sliding impact cylinder 200. The first clamping part 300 and the second clamping part 400 cooperate to clamp the insulating rod 100 from both sides to achieve the connection between them.

[0058] In this configuration, after the first clamping part 300, the second clamping part 400, and the sliding impact cylinder 200 are installed on the insulating rod body 100, the distance between the two first clamping parts 300 and the distance between the two second clamping parts 400 are greater than the length of the sliding impact cylinder 200, so as to leave room for the sliding impact cylinder 200 to move, so that the sliding impact sleeve can forcefully impact at least one of the first clamping part 300 and the second clamping part 400 at the same end.

[0059] It is understandable that the first clamping part 300, the second clamping part 400 and the sliding impact cylinder 200 are all made of hard materials to effectively withstand impact forces.

[0060] For example, the sliding impact cylinder 200, the first clamping part 300, and the second clamping part 400 are all made of metal materials, such as stainless steel, high manganese steel, high-strength low alloy steel, tungsten carbide alloy, etc. Of course, they can also be other hard materials that can effectively withstand impact force and transmit the impact force to the insulating rod 100. This embodiment does not limit them.

[0061] When operating through the insulating structure, if a large force is required, such as when pulling down the knife switch, the hook can be connected to the knife switch, and then the sliding impact cylinder 200 can be moved by an external force, such as by hand or with the help of a tool. The sliding impact cylinder 200 will strike at least one of the first clamping part 300 and the second clamping part 400 below. The resulting impact force will drive the insulating rod 100 to move, thereby causing the insulating rod 100 to pull the knife switch and pull it down smoothly. When it is necessary to close the switch, the sliding impact cylinder 200 is pulled to strike at least one of the first clamping part 300 and the second clamping part 400 above to assist in closing the switch. This can effectively improve the work efficiency of the operators and reduce the power outage time for users, thereby improving the reliability of power supply.

[0062] Meanwhile, during use, the height of the knife switch may vary. In this case, the first clamping part 300, the second clamping part 400 and the insulating rod 100 can be separated, and the positions of the first clamping part 300 and the second clamping part 400 on the insulating rod 100 can be adjusted so that the position of the sliding impact cylinder 200 is a position that is convenient for the user to operate after holding the insulating rod 100, thereby further improving the convenience of use.

[0063] In some possible implementations, both the first clamping part 300 and the second clamping part 400 are arc-shaped clamps, and the two ends of the arc-shaped clamps are provided with connecting ears 310. The connecting ears 310 of the first clamping part 300 and the second clamping part 400 are connected by bolts. That is, corresponding mounting holes are opened on the connecting ears 310 of the first clamping part 300 and the second clamping part 400, and the bolts are inserted into the mounting holes and locked by nuts to realize the connection between the first clamping part 300 and the second clamping part 400.

[0064] Specifically, the arc-shaped part of the arc-shaped clamp is adapted to the shape of the insulating rod 100. When the connecting lug 310 of the first clamping part 300 and the second clamping part 400 is locked by bolts, the arc-shaped clamp is attached to the insulating rod 100 and directly pressed against the insulating rod 100. This allows the first clamping part 300 and the second clamping part 400 to be stably attached to the insulating rod 100 when impacted by the sliding impact cylinder 200, and to withstand the impact force without moving along the insulating rod 100.

[0065] Understandably, the sliding impact cylinder 200 needs to move along the insulating rod 100. The inner diameter of the sliding impact cylinder 200 is larger than the outer diameter of the insulating rod 100, and there is a certain gap between the sliding impact cylinder 200 and the insulating rod 100 to prevent it from being difficult to move due to friction with the insulating rod 100. When both the first clamping part 300 and the second clamping part 400 are arc-shaped clamps, the thickness of at least one of the first clamping part 300 and the second clamping part 400 can be increased so that its projection in the length direction of the insulating rod 100 at least partially coincides with the sliding impact cylinder 200, so as to generate an impact with the sliding impact cylinder 200 and transmit the impact force to the insulating rod 100.

[0066] However, this method will increase the amount of material used in the first clamping part 300 and / or the second clamping part 400, increase the cost, and also increase the weight of the first clamping part 300 and the second clamping part 400.

[0067] To address this, the connecting ear 310 can be made to contact the sliding impact cylinder 200. It is only necessary to make the connecting ear 310 have a certain thickness to withstand the impact force of the sliding impact cylinder 200. Since the area of ​​the connecting ear 310 is small, even if the connecting ear 310 is thickened, it will not increase the amount of material used.

[0068] After numerous tests, it was found that when the first clamping part 300 and the second clamping part 400 are made of most metal materials, the thickness of the connecting ear 310 only needs to be greater than or equal to 4mm to meet the usage requirements. At the same time, when the sliding impact cylinder 200 is made of most metal materials, such as a stainless steel cylinder, the impact can be effectively carried out as long as the thickness of the cylinder wall is greater than or equal to 8mm.

[0069] It is understandable that when the connecting ear 310 is in contact with the sliding impact cylinder 200, the end of the connecting ear 310 should preferably extend to the outside of the sliding impact cylinder 200 to make effective contact.

[0070] In some possible implementations, the assist device for the insulation structure also includes an insulating pad 500 that is in contact with the surface of the insulating rod 100, a sliding impact cylinder 200 that is slidably sleeved on the outside of the insulating pad 500, and a first clamping part 300 and a second clamping part 400 clamping the insulating pad 500 on the side away from the insulating rod 100.

[0071] Specifically, the insulating pad 500 has a certain length, which can be spaced between the first clamping part 300 and the insulating rod 100, between the second clamping part 400 and the insulating rod 100, and between the sliding impact cylinder 200 and the insulating rod 100, so as to effectively protect the insulating rod 100 and also provide good insulation, thereby effectively improving the safety of operators using the insulating structure.

[0072] In addition, the surfaces of the insulating rod 100, the first clamping part 300, and the second clamping part 400 are generally smooth. After adding the insulating pad 500, the friction can be effectively increased, and the connection effect between the first clamping part 300, the second clamping part 400 and the insulating rod 100 can be improved.

[0073] In some possible implementations, multiple anti-slip protrusions can be added to the surface of the insulating pad 500 to increase the friction between the insulating pad 500 and the first clamping part 300, the second clamping part 400 and the insulating rod 100, thereby improving the stability of the connection.

[0074] In some possible implementations, the insulating pad 500 includes a first pad 510 and a second pad 520 disposed opposite to each other, both of which are configured to be arc-shaped.

[0075] Specifically, the shapes of the first pad 510 and the second pad 520 are adapted to the shape of the insulating rod 100. In use, the first pad 510 and the second pad 520 wrap around the outside of the insulating rod 100, which can play a good anti-slip and insulation role, and is also convenient for installation. They can be directly attached to the outside of the insulating rod 100 and then fixed to the insulating rod 100 by the first clamping part 300 and the second clamping part 400.

[0076] It is understood that the insulating pad 500 can also be other structures, as long as it can be effectively embedded between the first clamping part 300 and the insulating rod 100, and between the second insulating rod 100 and the second clamping part 400. This embodiment does not limit it.

[0077] For example, the insulating pad 500 includes multiple strip-shaped pads, which are placed sequentially on the outside of the insulating rod 100 and then fixed by the first clamping part 300 and the second clamping part 400.

[0078] For example, the insulating pad 500 can be a sheet structure, which can be directly bent and wrapped around the outside of the insulating rod 100 during assembly.

[0079] It is understandable that the insulating pad 500 does not need to completely cover the insulating rod 100, and a certain gap can be left. As long as it can cover most of the area of ​​the insulating rod 100 in that area and achieve a good insulation and anti-slip effect, this embodiment does not impose any restrictions on it.

[0080] In some possible implementations, both ends of the first pad 510 and the second pad 520 are provided with positioning protrusions 511, and the ends of the first clamping part 300 and the second clamping part 400 away from the sliding impact cylinder 200 abut against the positioning protrusions 511.

[0081] Taking the first pad 510 as an example, the distance between the two positioning protrusions 511 of the first pad 510 is equal to the sum of the distance between the two first clamping parts 300 and the length of the two first clamping parts 300, and is also equal to the sum of the distance between the two second clamping parts 400 and the length of the two second clamping parts 400.

[0082] After setting the positioning protrusion 511, the first clamping part 300 and the second clamping part 400 can be positioned, limiting the installation position of the first clamping part 300 and the second clamping part 400. When the first clamping part 300 and the second clamping part 400 are impacted by the sliding impact cylinder 200, the friction force can also be increased, which helps to improve the stability of the first clamping part 300 and the second clamping part 400 on the insulating rod body 100.

[0083] It is understood that the insulating pad 500 can be made of common materials that can increase friction and provide insulation, such as rubber, and this embodiment does not limit it.

[0084] When assembling the assist device of the insulating structure onto the insulating rod 100, firstly, place the first pad 510 and the second pad 520 on the surface of the insulating rod 100 from opposite sides, with the first pad 510 and the second pad 520 positioned so that the insulating rod 100 is away from the end facing the tool head. After symmetrically placing the first pad 510 and the second pad 520, slide the sliding impact cylinder 200 onto the insulating rod 100 from its end and move it to the position corresponding to the first pad 510 and the second pad 520. Then, place a first clamping part 300 and a... The second clamping part 400 is engaged at one end of the first pad 510 and the second pad 520. At this time, one end of the first clamping part 300 and the second clamping part 400 abuts against one end face of the positioning protrusion 511. Then, the connecting lug 310 of the first clamping part 300 and the second clamping part 400 is locked by bolts. Then, the other first clamping part 300 and the second clamping part 400 are fixed to the other end of the first pad 510 and the second pad 520 in the same way. Of course, the first clamping part 300 and the second clamping part 400 are both located between the two positioning protrusions 511 of the first pad 510 or the second pad 520.

[0085] For insulating rods 100 of different diameters, the first clamping part 300 and the second clamping part 400 of different sizes can be directly replaced. The insulating pad 500 is flexible and can be directly adapted to insulating rods 100 of different outer diameters. The sliding impact cylinder 200 has a large outer diameter and can also be directly adapted to insulating rods 100 of different outer diameters. Therefore, only the first clamping part 300 and the second clamping part 400 of different sizes need to be equipped to adapt to insulating rods 100 of different outer diameters, which has strong applicability.
