Description

Technical Field

[0001] The present disclosure relates to the field of power communication technologies, and particularly to an insulator fixing device and an insulator. Background Art

[0002] In a transmission line, the conductor is often suspended in a certain curved shape, and this curved shape will generate shear force. The shear force is the force exerted by the conductor on the insulator and the support structure under the action of its own gravity, wind load, etc. During the construction and operation of the transmission line, due to changes in various factors such as terrain, climate, and load, its suspension state will also change, and thus the shear force will also change accordingly, causing the insulator to bear a large shear force for a long time. Especially when installing wire poles in a curved section, since the wire poles are not distributed in a straight line section but extend along the tangent direction of the curve. This means that the wire will be subjected to an additional centrifugal force in the curved section. Especially in the case of a small curve radius or a large wire tension, this centrifugal force will be converted into a shear force on the insulator, thereby generating a greater shear force on the insulator. Over time, it will not only cause wear and fatigue of the insulator and the support structure, but also may affect the stability and safety of the entire transmission line. Summary of the Utility Model

[0003] The present disclosure provides an insulator fixing device and an insulator to improve the problem that the shear force generated by the wire is too large when installing wire poles in a curved section in the above background art, which has never caused wear to the insulator and affected the stability and safety of the entire transmission line.

[0004] In a first aspect, the present disclosure provides an insulator fixing device, including a support seat and a rotating seat. The support seat is used for fixedly connecting with a wire pole; the rotating seat is arranged on the support seat and is used for fixedly connecting with the insulator. The direction from one end of the rotating seat connected with the insulator to the other end far away from the rotating seat is parallel to the axial direction of the rotating seat.

[0005] In one embodiment, the rotating seat includes a flange chassis, a bearing, and a mounting plate. The flange chassis is fixedly connected with the support seat, the mounting plate is fixedly connected with the insulator, and the bearing is fixed on the flange chassis and connected with the mounting plate.

[0006] In one embodiment, the bearing is a sliding bearing.

[0007] In one embodiment, the support seat adjusts the installation height by changing the distance between the support frames.

[0008] In one embodiment, the support base includes a first support frame and a second support frame. The number of the first support frames is two, and the two first support frames are fixedly arranged on both sides of the wire support column and are arranged in parallel. The number of the second support frames is at least two. The second support frames span across the two first support frames and are fixedly connected to the first support frames. The second support frames are arranged in parallel with each other. The rotating base is fixedly arranged on the second support frame, and the height of the second support frame is adjustable.

[0009] In one embodiment, the first support frame is an angle steel, and the second support frame is arranged in a C shape.

[0010] In one embodiment, the second support frame includes a first sub-frame and a second sub-frame which are connected to each other. Both the first sub-frame and the second sub-frame are arranged in an L shape. The first sub-frame is connected to the first support frame, and the second sub-frame is connected to the rotating base. Perforations are spacedly arranged on the first sub-frame along the direction from near the first support frame to far from the first support frame. Through holes corresponding to the perforations are arranged on the second sub-frame. The perforations and the through holes are connected by fasteners.

[0011] In a second aspect, the present application provides an insulator, which includes an insulator body and the insulator fixing device according to any one of the above. The insulator body is fixedly connected to the insulator fixing device.

[0013] In one embodiment, an installation groove is arranged on the insulator body. The installation groove is used for fixing a wire, and an arc chamfer is arranged at the edge of the side wall of the installation groove in contact with the wire.

[0014] An insulator fixing device and an insulator provided by the present disclosure ensure the basic stability of the entire fixing device through the stable connection between the support base and the wire support column, providing a good foundation for resisting shear force. By arranging a rotating base under the insulator, the insulator can be rotated directionally within a certain range. This rotation can conform to the curve change when the wire support column is installed on a curved section, allowing the insulator and the connected wire to release and absorb part of the energy through rotation when subjected to the lateral (tangential) shear force caused by the curved installation section, rather than directly transmitting the shear force in the tangential direction to the fixing device or the insulator itself. Therefore, the shear force borne by the insulator can be significantly reduced, the service life of the insulator and the support structure can be prolonged, and the stability and safety of the entire transmission line are improved.

Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The embodiments of the present disclosure and each feature in the embodiments can be combined with each other without conflict, and the formed technical solutions are all within the protection scope of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0024] Example 1

[0025] Figure 1An insulator fixing device provided in an embodiment of the present disclosure includes a support base 100 and a rotating base 200. The support base 100 is used to be fixedly connected to a wire support 300; the rotating base 200 is arranged on the support base 100, and the rotating base 200 is used to be fixedly connected to the insulator. The axial direction of the rotating base 200 is parallel to the direction from one end of the insulator connected to the rotating base 200 to the other end away from the rotating base 200.

[0026] It can be understood that shear force is a force generated when two objects move or attempt to move relative to each other on a contact surface in a direction parallel to the contact surface. In the power system, the wires may swing due to wind, temperature changes or load changes, and these swings will be converted into shear forces on the insulators. Long-term effects may cause the insulators to loosen, be damaged or even fall off, affecting the stable operation of the power system. When installing wire poles on curved sections, the wire support 300 is not distributed in a straight line, but extends along the tangent direction of the curve. This means that the wires will be subject to additional centrifugal force on the curved sections, especially when the curve radius is small or the wire tension is large. This centrifugal force will be converted into shear force on the insulators, thereby generating greater shear force on the insulators.

[0027] In this embodiment, support base 100 is fixedly connected to power line support 300, ensuring the stability of the entire fixture. A stable support base is the first step in resisting shear forces, reducing the shaking of the entire fixture and insulator caused by the swinging of the power line. Support base 100 can be made of high-strength, corrosion-resistant materials such as cast iron, stainless steel, or alloy steel to enhance its load-bearing capacity and durability.

[0028] The rotating seat 200 is set on the support seat 100 and drives the insulator to rotate with a certain degree of freedom on the support seat 100. This rotation can adapt to the curve changes of the wires installed on the curved road section, allowing the insulator and the connected wires to release and absorb some energy through rotation when subjected to shear force, rather than directly transmitting the shear force in the tangential direction to the fixing device or the insulator itself. Therefore, it can significantly reduce the shear force on the insulator and extend the service life of the insulator and the supporting structure. The rotation angle of the insulator can be set to 90° rotation, 180° rotation, or 360° rotation, which is determined according to the actual installation requirements of the curved road section and is not limited here.

[0029] Furthermore, the axial direction of the rotating base 200 is parallel to the direction from the end where the insulator is connected to the rotating base 200 to the end far from the rotating base 200. This setting ensures the smoothness and effectiveness of rotation. When the wire swings due to external forces, the insulator can rotate slightly around the central axis of the rotating base 200, thereby dispersing and reducing the impact of shear forces. The inside of the rotating base 200 can also include sealing and lubrication mechanisms to reduce friction and wear during rotation, further improving its durability and reliability.

[0030] In summary, in this embodiment, through the stable connection between the support base 100 and the wire support 300, the basic stability of the entire fixing device is ensured. By dispersing and absorbing the shear forces in the tangential direction by the rotating base 200, the shear forces borne by the insulator are significantly reduced, making the entire insulator fixing device exhibit higher stability and lower damage when facing wire swings, extending the service life of the insulator and the support structure, and improving the stability and safety of the entire transmission line.

[0031] In one embodiment, the rotating base 200 includes a flange chassis 210, a bearing 220, and a mounting plate 230. The flange chassis 210 is fixedly connected to the support base 100, the mounting plate 230 is fixedly connected to the insulator, and the bearing 220 is fixed on the flange chassis 210 and connected to the mounting plate 230.

[0032] In this embodiment, the flange chassis 210 serves as the basic part of the rotating base 200, and its main function is to achieve a stable fixed connection with the support base 100. The connection can be completed by bolts, welding, or other reliable mechanical methods to ensure that the rotating base 200 can be firmly installed on the wire support and withstand various forces and torques from the wire. The flange chassis 210 is made of high-strength and corrosion-resistant materials such as cast iron, stainless steel, or alloy steel to adapt to the harsh outdoor environmental conditions and ensure the stability and reliability of long-term use. Multiple mounting holes, positioning pin holes, or reinforcing ribs and other structures can be provided on the flange chassis 210 to facilitate the precise alignment and firm connection with the support base 100, and at the same time improve the rigidity and load-bearing capacity of the overall structure.

[0033] The bearing 220 is the core component in the rotating base 200, located between the flange chassis 210 and the mounting plate 230, providing the necessary support and lubrication for the rotation of the mounting plate 230. According to specific application scenarios and requirements, different types of rolling bearings 220 (such as ball bearings 220, roller bearings 220) or sliding bearings 220 can be selected for the bearing 220.

[0034] The mounting disc 230 is the component in the rotating base 200 that is directly connected to the insulator. It is used to firmly fix the insulator on the rotating base 200 and ensure that the insulator can rotate together when the wire swings. Similar to the flange chassis 210, the mounting disc 230 is also made of high-strength and corrosion-resistant materials to adapt to the outdoor environment and withstand various forces and torques from the wire. The connection between the mounting disc 230 and the insulator can be made by bolts, clamps or other reliable mechanical means. These connection methods should ensure that the insulator will not loosen or fall off during rotation and can effectively transfer these forces to the rotating base 200 and the support base 100 when subjected to shear forces.

[0035] In one embodiment, the bearing 220 is a sliding bearing 220.

[0036] In this embodiment, the sliding bearing 220 is selected as the bearing 220. The reason is that the sliding bearing 220 has a surface contact, so it has a large load-bearing capacity; the oil film on the working surface of the sliding bearing 220 has the functions of vibration damping, buffering and noise reduction, and can work under special working conditions, such as underwater, corrosive media or non-lubricating media conditions, etc. Therefore, it works stably and has little noise. When in the liquid friction state, the bearing 220 has a small friction coefficient, slight wear and a long service life. At the same time, it can also achieve a very high rotational accuracy.

[0037] In one embodiment, the support base 100 is further configured to adjust the installation height of the rotating base 200.

[0038] With the continuous upgrading and transformation of the railway power supply system, it has been upgraded from the original direct supply plus return and BT power supply systems to the AT power supply system (autotransformer) with stable power supply performance. Therefore, the positive feeder has become a common line in the railway system. Railways are generally more in mountainous areas, and the positive feeder is generally erected on the field side of the catenary pole. In difficult mountainous areas, the distance to the slope protection is relatively close, which is likely to cause insufficient safety distance for slope protection construction, and accidents such as positive feeder grounding, blasting and wire breakage often occur. Therefore, to improve such problems, the insulator or the positive feeder can be fixed at a higher position to meet the safety distance for slope protection construction. In order to enable the fixing device to adapt to different height installation requirements, the support base 100 is set to be height-adjustable, which improves the practicability of the fixing device.

[0039] Such as Figure 3As shown, in one embodiment, the support base 100 includes a first support frame 110 and a second support frame 120. The number of the first support frames 110 is two, and the two first support frames 110 are fixedly arranged on both sides of the wire support 300 and are arranged in parallel. The number of the second support frames 120 is at least two. The second support frames 120 span across the two first support frames 110 and are fixedly connected to the first support frames 110. The second support frames 120 are arranged in parallel with each other. The rotating base 200 is fixedly arranged on the second support frames 120, and the height of the second support frames 120 is adjustable.

[0040] In this embodiment, in order to enable the support base 100 to stably support and fix the rotating base 200 and the insulators thereon, a layered structure including a first support frame 110 and a second support frame 120 is adopted to ensure the stability and adjustability of the structure.

[0041] Specifically, the number of the first support frames 110 is two, which are respectively fixedly arranged on both sides of the wire support 300, so that the two first support frames 110 can jointly bear the weight and force from the wire, enhancing the lateral stability of the support base 100. The two first support frames 110 are parallel in the horizontal direction to ensure uniform force transmission between them and avoid stress concentration caused by imbalance. The fixed connection between the first support frame 110 and the wire support 300 can be achieved by bolts, welding or other reliable mechanical means to ensure that the first support frame 110 can be firmly fixed on the wire support 300 to withstand various forces and torques from the wire.

[0042] The second support frames 120 span across the two first support frames 110, thereby forming a stable frame structure with the first support frames 110, which helps to enhance the stiffness of the support base 100, disperse the vertical force from the wire, and reduce the stress concentration on a single component. The height adjustment mechanism of the second support frames 120 can include screw adjustment, slide rail adjustment or other forms of mechanical adjustment devices.

[0043] Such as Figure 4As shown, in one embodiment, the second support frame 120 includes a first sub-frame 121 and a second sub-frame 122. Both the first sub-frame 121 and the second sub-frame 122 are L-shaped. After the first sub-frame 121 is connected to the second sub-frame 122, the second support frame 120 is C-shaped. The first sub-frame 121 is connected to the first support frame 110, and the second sub-frame 122 is connected to the rotating base 200. Perforations are spaced along the direction from near the first support frame 110 to far from the first support frame 110 on the first sub-frame 121. Through holes corresponding to the perforations are provided on the second sub-frame 122. Bolts are passed through between the perforations and the through holes. The width of the head end of the bolt is greater than the perforation. The head end of the bolt abuts against the side wall edge of the perforation and at least partially protrudes from the through hole. A nut threadedly engaged with the bolt is provided on the part of the bolt protruding from the through hole.

[0044] In this embodiment, after the first sub-frame 121 is connected to the second sub-frame 122, the second support frame 120 is C-shaped, enabling the second support frame 120 to be better connected to the first sub-frame 121 and the rotating base 200. Multiple perforations are spaced along the direction from near the first support frame 110 to far from the first support frame 110 on the first sub-frame 121. The arrangement of these perforations allows the height of the second support frame 120 (as well as the rotating base 200 and the insulator) to be adjusted by changing the position of the perforation through which the bolt passes. Through holes corresponding to these perforations are provided on the second sub-frame 122 so that the bolts can pass through and fix the two.

[0045] The bolts are passed through the perforations on the first sub-frame 121 and the through holes on the second sub-frame 122, and nuts threadedly engaged with the bolts are installed on the parts protruding from the through holes. The width of the head end of the bolt is greater than the diameter of the perforation. Therefore, when the bolt is tightened, its head end will abut against the side wall edge of the perforation, preventing the bolt from coming out of the perforation. At the same time, the nut is tightened on the bolt to further fix the relative positions of the first sub-frame 121 and the second sub-frame 122, thereby realizing the functions of height adjustment and stable support.

[0046] In one embodiment, the second support frame 120 can also be provided with different height specifications, such as 20 cm, 30 cm, etc. The installer selects a second support frame 120 with a suitable height specification according to the actual installation requirements for assembly with the first support frame 110, thereby further reducing the installation workload.

[0047] In one embodiment, the first support frame is an angle steel.

[0048] In this embodiment, the first support frame 110 is made of angle steel. Angle steel can withstand large tensile and compressive forces, and can effectively support and transmit the weight and force from the electric wire, ensuring the stability and safety of the support structure. The cross-section of the angle steel is in an "L" shape, and this shape endows it with good load-bearing capacity and stability. When used as the first support frame 110, the "L" shaped cross-section of the angle steel can effectively disperse the load and reduce stress concentration, thereby improving the overall stability of the support structure. At the same time, the cross-sectional shape of the angle steel is simple, and it is easy to perform processing operations such as cutting, drilling, bending, and welding. This greatly simplifies the processing and installation process of the first support frame 110 and improves the construction efficiency. At the same time, the angle steel is also convenient for connecting and fixing with other components, making the construction of the entire support structure more convenient and fast.

[0049] As Figure 4 shown, on the basis of the above embodiment, this embodiment provides an insulator, which includes an insulator body 400 and the insulator fixing device described in any one of the above embodiments, and the insulator body 400 is fixedly connected to the insulator fixing device. The insulator of this embodiment can have strong shear resistance under different terrain and climate conditions, etc., and the complexity and cost of installation and maintenance are relatively low, meeting the requirements of the sustainable development of the power industry.

[0050] In one embodiment, an installation groove 401 is provided on the insulator body 400, and the installation groove 401 is used to fix the electric wire, and an arc chamfer is provided at the edge of the side wall of the installation groove 401 in contact with the electric wire.

[0051] The electric wire may produce slight movement in the installation groove 401 due to factors such as wind vibration and temperature change. At the same time, combined with its own gravity, it will generate a large pressure on the point where it contacts the installation groove 401, and this pressure is the vertical shear force generated by the electric wire on the insulator in the gravity direction. If the contact edge is a right angle or an acute angle, then stress concentration will occur at these points, which will lead to an increase in the friction between the electric wire and the insulator body 400, accelerating wear, and easily causing local damage to the insulator body 400 or the electric wire in the long run. The design of the arc chamfer can reduce the contact area between the electric wire and the edge of the installation groove 401, thereby reducing the friction coefficient and reducing wear. At the same time, the arc surface is also more conducive to the sliding of the electric wire, reducing the resistance generated by friction.

[0052] Therefore, by providing an arc chamfer at the edge of the side wall of the installation groove 401 of the insulator in contact with the electric wire, and combining with the rotation function of the rotating seat 200, it can effectively reduce the shear forces received by the insulator in the tangential and vertical directions at the same time, greatly improving the stability of the insulator structure, and at the same time helping to reduce the damage rate of the electric wire, making the stability and safety of the entire transmission line significantly improved.

[0053] In one embodiment, a method for fixing an insulator is provided, which is applied to the fixing of the insulator in the above embodiment, and includes: determining an operation point on the slope protection and the distance between the operation point and the target wire support 300; calculating the safe installation distance of the insulator adapted to the operation point according to a preset safe construction standard; calculating the installation height of the insulator on the target wire support 300 by using the Pythagorean theorem according to the safe installation distance and the distance between the operation point and the target wire support 300; and installing the insulator according to the installation height.

[0054] In this embodiment, as Figure 5 shown, in the original installation method, the operation point on the slope protection is only 2 m away from the catenary, and there are great potential safety hazards in construction. After installing according to the method of this application, the catenary is installed at the top. After the installation, the wire is 2400 mm higher than the original horizontal height. According to the Pythagorean theorem, it is calculated that the catenary is 7 m away from the slope protection after being set at the top, and the line safety distance meets the requirements.

[0055] During installation, the height of the second support frame 120 can be adjusted on the ground first, and the rotary seat 200 can be assembled. Then, the first support frame 110 and the second support frame 120 are installed, the rotary seat 200 is fixed on the second support frame 120, and finally the insulator is installed, and the catenary is fixed in the installation groove 401.

[0056] Embodiment Two

[0057] On the basis of the above embodiment, this embodiment provides an application example. In this embodiment, an insulator is provided, which includes an insulator body 400, a support seat 100 and a rotary seat 200. The support seat 100 is used for fixedly connecting with the wire support 300; the rotary seat 200 is arranged on the support seat 100, and the rotary seat 200 is used for fixedly connecting with the insulator body 400. The axial direction of the rotary seat 200 is parallel to the direction from one end of the insulator body 400 connected to the rotary seat 200 to the end far away from the rotary seat 200. An installation groove 401 is arranged on the insulator body 400, and the installation groove 401 is used for fixing a wire. An arc chamfer is arranged at the edge of the side wall of the installation groove 401 in contact with the wire, and the insulator body 400 is a columnar insulator body 400.

[0058] In this embodiment, the stable connection between the support base 100 and the wire support column 300 ensures the basic stability of the entire fixing device, providing a good foundation for resisting shear force. By arranging the rotating base 200 below the insulator, the insulator can be rotated directionally within a certain range. This rotation can conform to the curve change when the wire support column 300 is installed on a curved section, allowing the insulator and the connected wire to release and absorb part of the energy through rotation when subjected to the lateral (tangential) shear force caused by the curved installation section, rather than directly transmitting the shear force in the tangential direction to the fixing device or the insulator itself. Therefore, the shear force borne by the insulator can be significantly reduced. At the same time, the wire may move slightly in the installation groove 401 due to factors such as wind vibration and temperature change. Combining with its own gravity, it will generate a large pressure on the point where it contacts the installation groove 401. This pressure is the vertical shear force generated by the wire on the insulator in the gravity direction. If the contact edge is a right angle or an acute angle, stress concentration will occur at these points, resulting in an increase in the friction between the wire and the insulator body 400, accelerating wear, and easily causing local damage to the insulator body 400 or the wire in the long term. The design of the arc chamfer can reduce the contact area between the wire and the edge of the installation groove 401, thereby reducing the friction coefficient and wear. At the same time, the arc surface is also more conducive to the sliding of the wire, reducing the resistance generated by friction. Through the combination of the rotating base 200 and the arc chamfer structure of the installation groove 401, the two cooperate with each other to reduce the shear force borne by the insulator in the lateral and vertical directions respectively, and can better adapt to the installation requirements of different terrains. Therefore, the structural strength is higher, and the service life of the insulator and the support structure is greatly extended.

[0059] The support base 100 is further configured to adjust the installation height of the rotating base 200. The support base 100 includes a first support frame 110 and a second support frame 120. The number of the first support frames 110 is two. The two first support frames 110 are fixedly arranged on both sides of the wire support column 300, and the two first support frames 110 are arranged in parallel. The number of the second support frames 120 is at least two. The second support frames 120 span across the two first support frames 110 and are fixedly connected to the first support frames 110. The second support frames 120 are arranged in parallel with each other. The rotating base 200 is fixedly arranged on the second support frame 120, and the height of the second support frame 120 is adjustable.

[0060] The rotating base 200 includes a flange chassis 210, a bearing 220, and a mounting plate 230. The flange chassis 210 is fixedly connected to the support base 100, the mounting plate 230 is fixedly connected to the insulator, and the bearing 220 is fixed on the flange chassis 210 and connected to the mounting plate 230. The bearing 220 is a sliding bearing 220. The sliding bearing 220 adopts surface contact, so it has a large load-bearing capacity; the oil film on the working surface of the sliding bearing 220 has the functions of vibration reduction, buffering, and noise reduction, and can work under special working conditions, such as working underwater, in corrosive media, or without lubricating media, etc. Therefore, it works stably and has low noise. In the liquid friction state, the bearing 220 has a small friction coefficient, slight wear, and a long service life. At the same time, it can also achieve a very high rotational accuracy.

[0061] Specifically, the first support frame 110 is an angle steel. Two angle steels are fixed on both sides of the wire support 300 by bolts. The two angle steels are parallel and at the same height. Above the first support frame 110, two second support frames 120 are fixed by bolts. The two second support frames 120 span across the first support frame 110 and are parallel to each other. The two first support frames 110 and the two second support frames 120 form a "well"-shaped fixed structure. The second support frame 120 can be arranged above the top of the wire support 300 or on the side of the wire support 300.

[0062] Four fixing holes are formed through the second support frame 120. Two fixing holes are formed on each second support frame 120. Four mounting holes are formed on the flange chassis 210. Each mounting hole corresponds to a fixing hole, and threads are provided in the mounting holes. When installing the rotating base 200, first align the mounting holes of the flange chassis 210 with the fixing holes one by one, and then use a screw rod adapted to the threads to pass through the fixing holes and the mounting holes to fix the two, so that the installation of the rotating base 200 can be quickly completed.

[0063] The second support frame 120 includes a first sub-frame 121 and a second sub-frame 122. Both the first sub-frame 121 and the second sub-frame 122 are arranged in an L shape. After the first sub-frame 121 and the second sub-frame 122 are connected, the second support frame 120 is arranged in a C shape.
