Description

Technical Field

[0001] This invention relates to the field of insulation protection technology for power equipment, specifically to a live-line installation mechanism for an insulation cover suitable for voltage transformers. Background Technology

[0002] A voltage transformer is a voltage converter used to protect valuable equipment, motors, and transformers in power distribution lines when faults occur. It is also used to measure the voltage, power, and energy of the lines. Voltage transformers are indispensable electrical appliances in power grid distribution lines. Because power distribution lines often pass through mountainous areas and residential buildings, there are numerous potential hazards from trees and buildings, which can easily lead to partial faults in the distribution lines. To ensure that voltage transformers on distribution lines can function properly, exposed voltage transformers need to be fitted with insulating covers. These insulating covers effectively prevent power outages and electric shocks caused by human contact or small animals.

[0003] Currently, there are two modes of installation for insulating covers: power-off installation and power-on installation. Since the entire power distribution line involves a large number of users, in order to improve power supply reliability and minimize the number of users affected by power outages, power-on installation is required. For power-on installation of insulating covers, power-on installation tools or power-on work vehicles can be used to enter the construction site. However, the construction environment in most mountainous areas and residential buildings cannot meet the requirements for power-on work vehicles. In this case, power-on installation tools need to be selected to ensure that installation can be carried out without power failure.

[0004] Existing technology discloses a live-line installation tool for an insulating cover. The insulating cover includes two housings opposite each other mounted on a terminal block and a connector detachably connected to the housings. The installation tool includes a removal assembly and an installation assembly. The removal assembly includes a first insulating rod and an operating hook connected to the first insulating rod. The operating hook can extend between the two housings and move the connector to separate the connector from one of the housings. The installation assembly includes a second insulating rod and a clamping assembly connected to the second insulating rod. The clamping assembly can clamp the two housings and can drive the connector to connect to the two housings. The clamping assembly can engage with one end of the insulating cover, and the operating hook can extend from the other end of the insulating cover to separate the connector from one of the housings. After separation, the operating hook removes the two housings from the terminal block. This reduces the area required for installation, allowing the installation tool to be used in areas inaccessible by vehicles.

[0005] It has the following technical problems:

[0006] When installing the insulating cover, two operators are required, one holding the removal component and the other the installation component. The installation component is used to clamp the insulating cover to the designated position, and then the removal component is used for auxiliary positioning to complete the installation of the insulating cover. Similarly, two operators are required to work together to complete the disassembly. The actual installation and disassembly are quite cumbersome, difficult to operate, time-consuming, and inefficient. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide a live-line installation mechanism for the insulating cover of voltage transformers, which enables live-line installation operations. Installation and disassembly can be completed by one person without the need for multiple people to cooperate, making the operation simple and efficient.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This invention relates to a live-line mounting mechanism for an insulating cover suitable for voltage transformers, comprising an insulating cover and an operating rod;

[0010] The insulating cover includes a fixed housing, with movable plates that can be opened or closed on both sides of the fixed housing. When the two movable plates are closed, they enclose the fixed housing to form a cavity in which a voltage transformer can be fitted. The fixed housing is provided with a spring-loaded structure, which is connected to the movable plates and is used to drive the movable plates to close elastically.

[0011] The top of the operating lever is equipped with a cover sliding mechanism, and there are sliding grooves on both sides of the cover sliding mechanism. The two sliding grooves are slidably connected to the two open movable plates of the insulating cover.

[0012] With this structure, the two movable plates of the insulating cover are opened relative to each other and slidably connected to the sliding grooves on both sides of the cover sliding mechanism at the top of the operating rod. The cavity of the insulating cover is opened using the cover sliding mechanism, and the insulating cover is sent to the voltage transformer using the operating rod. The opened cavity can be directly fitted onto the voltage transformer. Since both movable plates are connected to the spring-loaded structure, when the cover sliding mechanism slides away from the insulating cover, the two movable plates elastically close under the action of the spring-loaded structure, thus completing the installation. The entire installation process does not require a live-line working vehicle, and one person can complete the installation and disassembly without the need for multiple people to cooperate. It can maintain a certain distance from the power distribution line to avoid electric shock caused by touching the circuit. The insulating cover can be installed while the power is on. The installation and disassembly process is simple, efficient, and has low requirements for the construction environment.

[0013] Furthermore, the cover sliding mechanism includes a support gripper with two supporting feet spaced apart, and a sliding groove located on the side of the supporting feet. With this structure, the two supporting feet of the support gripper slide onto two movable plates respectively, facilitating the rapid sliding of the movable plates onto or off the supporting feet. This, in turn, facilitates the rapid sliding of the insulating cover onto or off the operating rod, making the installation and disassembly of the insulating cover simpler and more convenient. Installation and disassembly can be completed by a single operator, resulting in higher efficiency.

[0014] Furthermore, the slide groove is equipped with an anti-slip structure to prevent the movable plate from sliding out of the slide groove without external force. With this structure, when the movable plate is slidably connected to the slot, the anti-slip structure in the slot limits the displacement of the movable plate and prevents the movable plate from automatically sliding out of the slot without external force.

[0015] Furthermore, the operating lever includes a rotation adjustment mechanism, a first elevation angle adjustment mechanism, and a connecting rod. One end of the first elevation angle adjustment mechanism is connected to the connecting rod and is used to adjust the elevation angle of the support grab. The two ends of the rotation adjustment mechanism are respectively connected to the other end of the first elevation angle adjustment mechanism and the support grab, and are used to adjust the circumferential rotation angle of the support grab. With this structure, the first elevation angle adjustment mechanism is used to rotate relative to the connecting rod to adjust the elevation angle of the support grab, and the rotation adjustment mechanism is used to adjust the circumferential angle of the support grab. This enables multi-dimensional and multi-directional operation of the operating lever, thereby achieving the angle required for the installation of the insulating cover and ensuring that the insulating cover can be installed smoothly on the construction site.

[0016] Furthermore, the first elevation angle adjustment mechanism includes a first mounting base and a first rotating base that are fixedly installed. The first mounting base is connected to the connecting rod, and a first flange is provided on the side of the first mounting base. A first concave annular groove is provided on the corresponding side of the first rotating base. The first flange is rotatably connected in the first concave annular groove, and the support grab is connected to the first rotating base. With this structure, the first flange on the side of the first mounting base and the first concave annular groove on the corresponding side of the first rotating base cooperate to rotate. The structure is simple, the relative rotation operation is simple, and it is convenient to adjust the elevation angle of the support grab vertically to meet the required installation angle.

[0017] Furthermore, the rotation adjustment mechanism includes a third mounting base, which is fixedly connected to the first rotating base. The support grab also has a third rotating base, with a third flange on the third mounting base and a third concave annular groove on the third rotating base. The third flange is rotatably connected to the third concave annular groove. With this structure, the third flange of the third mounting base rotates in conjunction with the third concave annular groove of the third rotating base. The structure is simple, the relative rotation operation is easy, and the support grab can rotate around its own circumference, which is beneficial for adapting to various installation angles on the construction site.

[0018] Furthermore, the operating lever also includes a fixing mechanism and a support rod, with the other end of the connecting rod connected to the fixing mechanism and the support rod passing through the fixing mechanism.

[0019] Furthermore, the fixing mechanism includes a second elevation angle adjustment mechanism and a clamp assembly. The second elevation angle adjustment mechanism is connected to the connecting rod, and its side is connected to the clamp assembly for adjusting the elevation angle of the support grab. The support rod passes through the clamp assembly. With this structure, the relative rotation between the second elevation angle adjustment mechanism and the clamp assembly allows for further adjustment of the elevation angle of the support grab, thus adapting to more installation angles on the construction site.

[0020] Furthermore, the second elevation angle adjustment mechanism includes a second mounting base and a second rotating base. The second mounting base is connected to the connecting rod. The side of the second mounting base has several limiting protrusions evenly distributed around its circumference, and the corresponding side of the second rotating base has several limiting grooves evenly distributed around its circumference. The limiting protrusions engage with the corresponding limiting grooves. With this structure, the limiting protrusions and limiting grooves can rotate relative to each other and then engage, which facilitates further adjustment of the elevation angle of the support grab and also helps prevent relative rotation between the second mounting base and the second rotating base, improving the fastening effect.

[0021] Furthermore, the clamp assembly includes a first semicircular clamp and a second semicircular clamp. The first semicircular clamp is located on the side of the second rotating seat, and the first and second semicircular clamps enclose and are fitted onto the support rod. With this structure, the first and second semicircular clamps can be matched with support rods of various sizes after being enclosed, and the structure is simple, with simple and efficient installation and disassembly operations.

[0022] In summary, the present invention has the following advantages:

[0023] During installation, the two movable plates of the insulating cover are opened relative to each other and slidably connected to the sliding grooves on both sides of the cover sliding mechanism at the top of the operating rod. The cavity of the insulating cover is opened using the cover sliding mechanism, and the insulating cover is then moved upward to the voltage transformer using the operating rod. The opened cavity can be directly fitted onto the voltage transformer. Since both movable plates are connected to the spring-loaded structure, when the cover sliding mechanism slides away from the insulating cover, the two movable plates elastically close under the action of the spring-loaded structure, thus completing the installation. The entire installation process does not require a live-line work vehicle, and one person can complete the installation and disassembly without the need for multiple people. This allows for maintaining a certain distance from power lines, avoiding electric shock from contact with the circuit. The insulating cover can be installed while the circuit is energized. The installation and disassembly process is simple, efficient, and has low requirements for the construction environment. Attached Figure Description

Detailed Implementation

[0032] The present invention will now be described in further detail.

[0033] like Figure 1 and Figure 2 As shown, an insulating cover live-line installation mechanism suitable for voltage transformers includes an insulating cover 1 and an operating rod;

[0034] The insulating cover 1 includes a fixed housing, and movable plates 6 that can be opened or closed are respectively provided on both sides of the fixed housing. When the two movable plates 6 are closed, they enclose the fixed housing to form a cavity in which a voltage transformer can be fitted. The fixed housing is provided with a spring structure 9, which is connected to the movable plates 6 and is used to drive the movable plates 6 to close elastically.

[0035] The top of the operating lever is equipped with a cover sliding mechanism, and the two sides of the cover sliding mechanism are respectively equipped with sliding grooves 47. The two sliding grooves 47 are slidably connected to the two open movable plates 6 of the insulating cover 1.

[0036] Specifically, the movable plate 6 of the insulating cover 1 includes a concave plate 7 and an arc plate 8. The concave plate 7 is snapped into the sliding groove. One end of the arc plate 8 is fixed to the concave plate 7, and the other end of the arc plate 8 is provided with a spring-loaded structure 9. The spring-loaded structure 9 is located in the fixed housing and is used to make the movable plate 6 spring back and close when no force is applied.

[0037] After opening the two movable plates 6, an opening 10 is formed, which opens the chamber. The opened chamber can be directly and quickly fitted onto the voltage transformer. Since the arc plate 8 has a self-rebound structure 9, the concave plate 7 is automatically reset by the arc plate 8 without external force, which in turn drives the movable plate 6 to automatically reset. When both relative movable plates 6 are reset, a closed state is formed. During construction, only the fitting step needs to be completed, and the insulating cover 1 can be automatically fixed onto the voltage transformer. Only one person needs to operate to complete the installation and disassembly. No multiple people are required to cooperate. The installation and operation are convenient and efficient. After installation, it can effectively prevent faults in the power distribution line caused by human or small animal contact, and improve the reliability of the power supply of the power distribution line.

[0038] Specifically, such as Figure 5 As shown, the protective cover sliding mechanism includes a support gripper 11, which includes two support legs arranged in a figure-eight shape. The ends of the support legs are provided with outward-facing sliding grooves 47, and the end of the concave plate 7 of the movable plate 6 is slidably connected to the sliding grooves 47.

[0039] The slide groove 47 is equipped with an anti-slip structure, which includes a slide groove recess 48 located in the middle of the slide groove 47. The slide groove recess 48 is obtuse-angled or arc-shaped. The slide groove 47 is divided into two parts with the slide groove recess 48 as the center, and the whole presents an obtuse-angled or arc-shaped form. Since the concave plate 7 of the insulating cover 1 is straight and has a certain degree of flexibility, when it is necessary to connect the cover sliding mechanism to the insulating cover 1, the concave plate 7 is first slid into the front half of the slide groove 47. Then, when the concave plate 7 passes through the slide groove recess 48, it is necessary to push the slide groove 47 with force to allow the concave plate 7 to enter the rear half of the slide groove 47. Similarly, when it is necessary to separate the cover sliding mechanism from the insulating cover 1, force is also required to disengage the cover sliding mechanism from the insulating cover 1. Therefore, the groove recess 48 in the middle of the groove 47 can play a good anti-slip role, preventing the insulating cover 1 from automatically sliding out of the groove 47 without external force, which is beneficial for workers to operate remotely on the ground.

[0040] The two supporting feet of the support gripper 11 are slidably connected between the two movable plates 6, allowing the insulating cover 1 to quickly slide onto or off the operating rod. The limiting effect of the groove recess 48 prevents the movable plate 6 from automatically sliding out of the slot without external force, effectively preventing the insulating cover 1 from detaching from the control of the operating rod during transmission or installation. After the voltage transformer is installed, the operating rod can be slid away from the insulating cover 1 along the extension direction of the groove 47 simply by moving the operating rod, making the installation and disassembly of the insulating cover 1 simpler and more convenient, allowing one person to complete the installation and disassembly, thus increasing efficiency.

[0041] like Figure 3 and Figure 4 As shown, the operating lever includes an operating component 2, a connecting rod 3, a fixing mechanism 4, and a support rod 5 connected in sequence.

[0042] Specifically, the operating component 2 includes a rotation adjustment mechanism 13 and a first elevation angle adjustment mechanism 12.

[0043] The first elevation angle adjustment mechanism 12 is connected to the connecting rod 3 at one end and is used to adjust the elevation angle of the support grab 11. The two ends of the rotation adjustment mechanism 13 are respectively hinged to the other end of the first elevation angle adjustment mechanism 12 and the support grab 11 and are used to adjust the circumferential rotation angle of the support grab 11.

[0044] The rotation adjustment mechanism 13 is provided with a third mounting seat 42, which is fixed to the first rotating seat 17. The upper end of the support claw 11 is provided with a third rotating seat 44. The third mounting seat 42 and the third rotating seat 44 are fixed with a third fixing bolt 39 and a third fixing nut 40. The third mounting seat 42 is provided with a third through hole 41 in the middle, and the third rotating seat 44 is provided with a third fixing hole 43 in the middle. The third fixing nut 40 is fixed in the third fixing hole 43. One end of the third fixing bolt 39 passes through the third through hole 41 and is connected to the third fixing nut 40. The end face of the third mounting seat 42 near the third rotating seat 44 is provided with a third flange 46. The end face of the third rotating seat 44 is provided with a third concave annular groove 45 corresponding to the third flange 46. During assembly, the third flange 46 is placed in the third concave annular groove 45. After adjusting the angle, the third fixing bolt 39 and the third fixing nut 40 are threadedly connected and fixed.

[0045] The third flange 46 and the third concave annular groove 45 rotate together, which is simple in structure and easy to operate. The support grab 11 can rotate around its own circumference, which is conducive to adapting to various installation angles on the construction site.

[0046] The first elevation angle adjustment mechanism 12 includes a first mounting base 16, a first rotating base 17, a first fixing bolt 20, a first fixing nut 21, and a first sleeve 24. One end of the first sleeve 24 is fixed to the first mounting base 16, and the other end is snapped into the connecting rod 3. The first mounting base 16 has a first through hole 22 in the middle, and the first rotating base 17 has a first fixing hole 23 in the middle. The first fixing nut 21 is fixed in the first fixing hole 23. One end of the first fixing bolt 20 passes through the first through hole 22 and is connected to the first fixing nut 21. The end face of the first mounting base 16 near the first rotating base 17 has a first flange 18. The end face of the rotating seat 17 is provided with a first concave annular groove 19 corresponding to the first flange 18. During assembly, the first flange 18 is placed in the first concave annular groove 19. After adjusting the angle, the first fixing bolt 20 and the first fixing nut 21 are engaged to form a threaded connection and fixation. The side wall of the first sleeve 24 is provided with a first fastening hole 25. A first locking bolt 26 is provided in conjunction with the first fastening hole 25. The first locking bolt 26 is threadedly connected to the first fastening hole 25. After passing through the first fastening hole 25, the first locking bolt 26 acts on the outer wall of the connecting rod 3. By tightening the first locking bolt 26, the connection between the first sleeve 24 and the connecting rod 3 becomes more secure.

[0047] The first flange 18 and the first concave annular groove 19 rotate together, which is simple in structure and easy to operate. It is also convenient to adjust the elevation angle of the support grab 11 up and down to meet the required installation angle.

[0048] Specifically, the fixing mechanism 4 includes a second elevation angle adjustment mechanism 14 and a clamp assembly 15;

[0049] The second elevation angle adjustment mechanism 14 is connected to the connecting rod 3, and its side is connected to the clamp assembly 15. It is used to adjust the elevation angle of the support grab 11. The support rod 5 passes through the clamp assembly 15. By utilizing the relative rotation between the second elevation angle adjustment mechanism 14 and the clamp assembly 15, the elevation angle of the support grab 11 can be further adjusted, thereby adapting to more installation angles on the construction site.

[0050] The second elevation adjustment mechanism 14 includes a second mounting base 33, a second rotating base 37, a second fixing bolt 30, a second fixing nut 38, and a second sleeve 27. One end of the second sleeve 27 is snapped onto the connecting rod 3, and the other end is fixed to the second mounting base 33. The second mounting base 33 has a second through hole 31 in the middle, and the second rotating base 37 has a second fixing hole 36 in the middle. The second fixing nut 38 is fixed in the second fixing hole 36. One end of the second fixing bolt 30 passes through the second through hole 31 and is connected to the second fixing nut 38. The end face of the second mounting base 33 near the second rotating base 37 has a second flange. The end face of the second rotating seat 37 is provided with a second concave annular groove corresponding to the second flange. During assembly, the second flange is placed in the second concave annular groove. After adjusting the angle, the second fixing bolt 30 and the second fixing nut 38 are engaged to form a threaded connection and fixation. The side wall of the second sleeve 27 is provided with a second fastening hole 28. A second locking bolt 29 is provided in conjunction with the second fastening hole 28. The second locking bolt 29 is threadedly connected to the second fastening hole 28. After passing through the second fastening hole 28, the second locking bolt 29 acts on the outer wall of the connecting rod 3. By tightening the second locking bolt 29, the connection between the second sleeve 27 and the connecting rod 3 becomes more secure. The top of the second flange is provided with several limiting protrusions 34 evenly around its circumference, and the bottom of the second concave annular groove is provided with several limiting grooves 35 evenly around its circumference. The limiting protrusions are engaged with the limiting grooves 35. After the second fixing bolt 30 and the second fixing nut 38 are threadedly connected and fixed, the engagement of the limiting protrusions 34 and the limiting grooves 35 prevents the second mounting seat 33 and the second rotating seat 37 from rotating relative to each other, further improving their fastening effect.

[0051] like Figure 6As shown, the clamp assembly 15 includes a first semi-circular clamp 55 fixedly connected to the side of the second rotating seat 37, a second semi-circular clamp 56 cooperating with the first semi-circular clamp 55, and a fourth locking bolt 49 connecting the first semi-circular clamp 55 and the second semi-circular clamp 56. The first semi-circular clamp 55 and the second semi-circular clamp 56 form a sleeve that can clamp the support rod 5. The first semi-circular clamp 55 has first connecting ears 51 at both ends, and a fourth fixing hole 52 in the middle of the first connecting ear 51. A fourth fixing nut 50 is fixed in the fourth fixing hole 52. The second semi-circular clamp 56 has second connecting ears 53 at both ends. 3. A U-shaped groove 54 corresponding to the fourth fixing hole 52 is provided. The opening direction of the U-shaped groove 54 is parallel to the length direction of the support rod 5. When locking, the two fourth locking bolts 49 can be connected to the fourth fixing nut 50. Then, the outer wall of the support rod 5 is pressed tightly against the middle of the first semi-circular clamp 55. Next, the U-shaped groove 54 of the second connecting ear 53 is aligned with the fourth locking bolt 49. The second semi-circular clamp 56 is moved along the length direction of the support rod 5 so that the first semi-circular clamp 55 and the second semi-circular clamp 56 surround to form a sleeve that clamps the support rod 5. Then, the fourth locking bolt 49 is further tightened to complete the connection and fixation of the operating rod and the support rod 5.

[0052] The first semicircular clamp 55 and the second semicircular clamp 56 can be combined to match support rods 5 of various sizes, and the structure is simple and easy to install and disassemble.

[0053] Specifically, support rod 5 is an adjustable telescopic rod, the length of which can be adjusted according to the installation needs at the construction site.

[0054] Specifically, the first fixing nut 21, the second fixing nut 38 and the third fixing nut 40 are all provided with threaded holes and guide holes. The inner diameter of the guide hole is larger than the inner diameter of the threaded hole, and the guide hole and the threaded hole are connected by a guide bevel.

[0055] Specifically, the end faces of the first mounting base 16, the second mounting base 33 and the third mounting base 42 are all recessed with a number of slots 32, which are distributed at intervals along the circumference. This saves materials, reduces weight, and ensures strength.

[0056] The advantages of this embodiment are as follows:

[0057] 1. The upper end of the operating rod grips the insulating cover 1, and the lower end is equipped with a telescopic support rod 5. The entire installation process does not require a live-line work vehicle, and one person can complete the installation and disassembly without the need for multiple people to cooperate. It can maintain a certain distance from the power distribution line to avoid touching the circuit and causing electric shock. The insulating cover 1 can be installed while the circuit is live. The installation and disassembly process is simple, efficient, and has low requirements for the construction environment.

[0058] 2. The support gripper 11 has a relatively stable gripping mechanism when holding the insulating cover 1 by utilizing the groove 47 and groove recess 48. After being delivered to the designated position, the support gripper 11 can also quickly detach from the insulating cover 1, making the operation simple and convenient.

[0059] 3. The first elevation angle adjustment mechanism 12 is used to rotate relative to the connecting rod 3 to adjust the elevation angle of the support grab 11. The second elevation angle adjustment mechanism 14 is used to rotate relative to the clamp assembly 15 to further adjust the angle required for the installation of the insulating cover 1. Then, the rotation adjustment mechanism 13 is used to rotate around its own circumference to adjust the circumferential angle of the support grab 11 and the support rod 5 to rotate around its own circumference. This achieves multi-dimensional and multi-directional operation, thereby achieving the angle required for the installation of the insulating cover 1 and ensuring that the insulating cover 1 can be installed smoothly on the construction site.

[0060] 4. Due to the U-shaped groove 54 structure of the clamp, disassembly and assembly operations can be performed without completely removing the fourth locking bolt 49. For example, when connecting the support rod 5, the two fourth locking bolts 49 can be initially connected to the fourth fixing nut 50. After the first semi-circular clamp 55 is pressed against the outer wall of the support rod 5, the U-shaped groove 54 of the second semi-circular clamp 56 is aligned with the fourth locking bolt 49. The second semi-circular clamp 56 is slid along the length of the support rod 5 to align with the first semi-circular clamp 55. Then, the fourth locking bolt 49 is further tightened to complete the connection and fixation. When disassembling, the process is reversed, and only the second semi-circular clamp 56 is disengaged, which can prevent parts from falling off or being lost.

[0061] 5. The first mounting base 16, the second mounting base 33 and the third mounting base 42 are formed by setting slots 32 to form a hollow structure, which reduces the overall weight and saves materials, while also ensuring structural strength (the connection between adjacent slots 32 is similar to a reinforcing rib).

[0062] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
