Description

Technical Field

[0001] This invention belongs to the field of electrical equipment insulation protection technology, and more specifically, it relates to an insulation cover installation mechanism and method 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] Currently, most existing methods for installing insulating covers on live circuits involve workers holding a rod with hooks, using the hooks to hold the insulating cover in place, and then using the rod to move the insulating cover above the voltage transformer for installation. Finally, the hooks are released to lower the insulating cover and complete the installation. However, in actual use, the existing installation methods have been found to have at least the following problems.

[0005] When installing the insulating cover by hand, workers are susceptible to the influence of voltage transformers and may be subject to electric shock or electrical leakage from other electrical components, posing a high risk.

[0006] When it is necessary to install insulation covers for voltage transformers in mountainous areas or residential buildings with complex road conditions, workers need to carry the installation tools by hand and move them through the complex road conditions, which is inconvenient and laborious. Therefore, most of the existing installation tools have the problem of being inconvenient to carry. Summary of the Invention

[0007] To at least solve one of the above-mentioned technical problems, the present invention provides an insulation cover installation mechanism and method suitable for voltage transformers.

[0008] To achieve the above objectives, the following technical solution is adopted:

[0009] Firstly, an insulating cover installation mechanism suitable for voltage transformers includes a box-shaped backpack and an insulating cover body. The four corners of the bottom of the box-shaped backpack are fixedly connected to casters. The box-shaped backpack is made of polycarbonate. A storage compartment for storing installation tools is opened in the middle of the top of the box-shaped backpack. A cover plate is hinged to the location of the storage compartment. Ten placement slots are opened on the side of the storage compartment on the top of the box-shaped backpack, and splicing mechanisms are fitted into each of the ten placement slots. A drive mechanism for driving the splicing mechanism is provided on the top of the box-shaped backpack on the other side of the storage compartment. A clamping mechanism for clamping and fixing the insulating cover body is placed inside the storage compartment. A connecting plate is fixedly connected to the bottom of the box-shaped backpack, and the connecting plate is connected to three support mechanisms for supporting and positioning the box-shaped backpack. A remote control mechanism for controlling the drive mechanism is fixedly installed on one side of the box-shaped backpack. The splicing mechanism includes a splicing rod, the drive mechanism includes a base plate, the support mechanism includes a plug rod, the remote control mechanism includes a handle sleeve and a Bluetooth remote control handle, and the clamping mechanism includes a pivot seat.

[0010] Preferably, the box-shaped backpack has two shoulder straps fixedly connected to the side away from the remote control mechanism, a sponge pad fixedly connected to the side away from the remote control mechanism, and elastic mesh bags fixedly connected to both sides of the box-shaped backpack.

[0011] Preferably, in addition to the side with the shoulder strap, the bottom of the other three side walls of the box-shaped backpack are fixedly connected to two connecting sleeves, and three insert rods are respectively sleeved inside the three sets of connecting sleeves. Each of the three insert rods is fixedly connected to a threaded connector.

[0012] Preferably, the connecting plate has three threaded grooves on one side, and the three threaded grooves are respectively adapted to three threaded connectors.

[0013] Preferably, the box-shaped backpack has a controller assembly located below the drive mechanism for controlling the drive mechanism in conjunction with a Bluetooth remote control handle. The controller assembly includes a power module, a Bluetooth communication module, a microcontroller, and a motor drive unit. The power module includes a battery and a power management chip, the Bluetooth communication module includes a Bluetooth chip and an antenna, and the motor drive unit includes a motor driver and a relay.

[0014] Preferably, a damping turntable is fixedly connected to the top of the box-shaped backpack, and a bottom plate is fixedly connected to the end of the damping turntable away from the box-shaped backpack. A servo motor is fixedly connected to the top of the bottom plate, and a reducer is provided at the output end of the servo motor. The reducer is fixedly connected to the top surface of the bottom plate, and the output end of the servo motor is adapted to the input end of the reducer. A mating sleeve is fixedly connected to the output end of the reducer, and the mating sleeve has a threaded connection groove.

[0015] Preferably, one end of the splicing rod is provided with a threaded mating groove, and the other end of the splicing rod is fixedly connected with a threaded connector, the threaded connector being adapted to the threaded connection groove, and the entire splicing rod is made of polytetrafluoroethylene.

[0016] Preferably, the handle cover is fixedly connected to the box-shaped backpack, the Bluetooth remote control handle is placed inside the handle cover, the side of the handle cover away from the box-shaped backpack is provided with a Velcro barbed layer, the top of the handle cover is fixedly connected with a strap, the end of the strap away from the handle cover is fixedly connected with a Velcro loop layer, and the Velcro loop layer and the Velcro barbed layer are compatible.

[0017] Preferably, the pivot seat is fixedly connected to a threaded joint, and the pivot seat is fixedly connected to a damped double-headed pivot. The damped double-headed pivot is a pivot that can rotate at both ends and has slight damping. The middle section of the damped double-headed pivot is fixedly connected to a limit fork.

[0018] Preferably, the threaded connector is adapted to the threaded mating groove, and the limiting fork is engaged with the insulating cover body.

[0019] Secondly, a method for installing an insulating cover suitable for voltage transformers includes the following steps:

[0020] The insulating cover body is snapped onto the limit fork of the clamping mechanism;

[0021] At least two splicing rods are axially spliced ​​together using a threaded joint and a threaded groove to form an operating rod;

[0022] One end of the assembled operating rod is threadedly connected to the mating sleeve of the drive mechanism, and the other end is connected to the threaded joint of the clamping mechanism.

[0023] The servo motor of the drive mechanism is controlled by a Bluetooth remote control handle to drive the operating lever to adjust the angle, so that the insulating cover body moves to the installation position of the voltage transformer.

[0024] After the insulating cover body is fitted onto the voltage transformer, the control drive mechanism drives the operating lever to rotate at a set angle, so that the limit fork disengages from the insulating cover body based on the rotation of the damped double-headed rotating shaft.

[0025] The support mechanism's insert rods are inserted into the ground or contact the paved ground through threaded connectors to achieve stable support for the box-shaped backpack.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In this invention, a drive mechanism is provided, and a controller assembly is controlled by a Bluetooth remote control handle to respond. The controller assembly controls the servo motor to start, and the servo motor drives the docking sleeve to rotate after being reduced in speed by a reducer. The rotation of the docking sleeve adjusts the angle of the rods formed by multiple splicing mechanisms, ultimately causing the clamping mechanism and the insulating cover body to rise or fall. Finally, the insulating cover body covers the voltage transformer. When the voltage transformer is covered by the insulating cover body, the position where an electric arc may occur is covered by the insulating cover body, greatly reducing the possibility of electric shock to workers. Subsequently, the worker can rotate the drive mechanism to change the angle of the clamping mechanism. Then, the limit fork rotates based on the damped double-headed rotating shaft. After the splicing mechanism drives the clamping mechanism to rotate a certain angle, the limit fork will disengage from the insulating cover body, completing the installation of the insulating cover body. This solves the problem of the high risk of live installation of existing insulating covers.

[0028] In this invention, a box-shaped backpack is provided, and the elastic mesh bags on both sides of the box-shaped backpack are elastic and can be used to store the insulating cover body, so that the insulating cover body can be transported together with the whole device, increasing portability. The clamping mechanism and other installation tools can be stored in the storage compartment, and the splicing mechanism can be placed in each placement slot, so that this application has high portability and solves the problem of low portability of existing installation mechanisms.

[0029] In this invention, by incorporating a box-shaped backpack, the device can be initially transported by vehicle. When traveling to mountainous areas or roads with poor accessibility, the entire device can be unloaded from the vehicle and moved using the four omnidirectional wheels at the bottom of the box-shaped backpack. When transporting on irregular roads, workers can directly carry the entire device on their backs using two shoulder straps, with sponge padding to enhance comfort. In this case, the entire device can be carried by workers in most environments (muddy roads, puddles, hillsides, gravel roads, and icy roads, etc.), giving the device high portability and thus facilitating transportation.

[0030] In this invention, by providing a splicing structure, when the installation position of the voltage transformer is relatively complex and there are other obstructions nearby, multiple splicing mechanisms can be spliced ​​together. Workers can directly hold the splicing mechanism to control the position of the clamping mechanism and the insulating cover body, and finally install the insulating cover body on the voltage transformer. This avoids the problem that the driving mechanism cannot be used due to environmental reasons, thus preventing the installation of the insulating cover body, and makes this application highly applicable.

[0031] In this invention, by providing a splicing structure, the splicing mechanisms can be interconnected, enabling the installation of insulating covers on voltage transformers at different positions and heights, thus giving this application high applicability.

[0032] In this invention, by providing support mechanisms, three support mechanisms can be removed from the threaded grooves and connected to three sets of connecting sleeves before installation. The stability of the box backpack can be increased by inserting the support mechanisms into the soil. When paving the road surface, the threaded connection head can be facing downwards. The three support mechanisms, together with the three sets of connecting sleeves, provide additional support for the box backpack, preventing the box backpack from falling due to uneven weight distribution, thus giving this application high stability.

[0084] Limiting fork 804: Fixed in the middle section of damped double-headed rotating shaft 803, used to engage the insulating cover body 9.

[0085] Working principle:

[0086] First, this application can be transported by vehicle. When traveling to mountainous areas or roads with inconvenient transportation, the entire device can be unloaded from the vehicle and moved by the four universal wheels 109 at the bottom of the box-shaped backpack 1. When it needs to be transported on irregular roads, the worker can carry the entire device on his back using two shoulder straps 101. The sponge pad 102 pads the worker's back to improve comfort. At this time, the entire device can be carried by the worker and transported in most environments (muddy roads, puddles, hillsides, gravel ground and icy roads, etc.), making this application highly portable and thus facilitating transportation.

[0087] The second step is to place the entire device down next to the voltage transformer after it has been transported to the location of the voltage transformer. Then, according to the distance between the device and the voltage transformer, the required splicing mechanism 2 is taken out from the placement slot 104. Then, each splicing mechanism 2 is spliced ​​together with the threaded mating slot 202 and the threaded connector 203. Finally, the threaded connector 203 is threadedly connected to the threaded connection slot 305. After installation, the clamping mechanism 8 is threadedly connected to the threaded mating slot 202 of the splicing mechanism 2 at the end away from the threaded connection slot 305 through the threaded connector 802. Finally, the insulating cover body 9 is snapped onto the limiting fork 804. After the preparation is completed, the Velcro layer 703 and the Velcro barbed layer 704 are separated. Then, the Bluetooth remote control handle 705 is removed from the handle sleeve 701. Then, the driving mechanism 3 is rotated by the damping turntable 107 to move the insulating cover body 9 to the position above the voltage transformer and then away from the box-shaped backpack 1.

[0088] The third step involves controlling the controller assembly 106 via the Bluetooth remote control handle 705. The controller assembly 106 then starts the servo motor 302. The servo motor 302, after being reduced in speed by the reducer 303, drives the docking sleeve 304 to rotate. The rotation of the docking sleeve 304 adjusts the angle of the rods formed by the multiple splicing mechanisms 2, ultimately causing the clamping mechanism 8 and the insulating cover body 9 to rise or fall. This allows the insulating cover body 9 to cover the voltage transformer. Once the voltage transformer is covered by the insulating cover body 9, the location where an electric arc might occur is covered, greatly reducing the possibility of electric shock to the worker. Subsequently, the worker can rotate the drive mechanism 3 to change the angle of the clamping mechanism 8. Then, the limit fork 804 rotates based on the damped double-headed rotating shaft 803. After the splicing mechanism 2 drives the clamping mechanism 8 to rotate a certain angle, the limit fork 804 will disengage from the insulating cover body 9, completing the installation of the insulating cover body 9.

[0089] Fourth step: Before installation, the three support mechanisms 6 can be removed from the threaded grooves 111 and connected to the three sets of connecting sleeves 4. The stability of the box backpack 1 can be increased by inserting the support mechanisms 6 into the soil. When paving the road surface, the threaded connector 602 end can be facing down. The three support mechanisms 6, together with the three sets of connecting sleeves 4, provide additional support for the box backpack 1 to prevent the box backpack 1 from falling due to uneven weight distribution. The support mechanisms 6 can be stored at the bottom of the box backpack 1 through the connecting plate 110 to make it highly portable.

[0090] Fifth, the elastic mesh bags 103 on both sides of the box-shaped backpack 1 are elastic and can be used to store the insulating cover body 9, so that the insulating cover body 9 can be transported together with the whole device, increasing portability. The clamping mechanism 8 and other installation tools can be stored in the storage compartment 105, and the splicing mechanism 2 can be placed in each placement slot 104, making this application highly portable.

[0091] The sixth step involves assembling multiple splicing mechanisms 2 when the installation location of the voltage transformer is complex and there are other obstructions nearby. Workers can directly hold the splicing mechanism 2 to control the position of the clamping mechanism 8 and the insulating cover body 9, and finally install the insulating cover body 9 on the voltage transformer. This avoids the problem that the driving mechanism 3 cannot be used due to environmental reasons, thus preventing the installation of the insulating cover body 9 and making this application highly applicable.

[0092] Example 2

[0093] An installation method for an insulating cover suitable for voltage transformers, based on the mechanism of Embodiment 1, includes the following steps:

[0094] The insulating cover body is snapped onto the limit fork of the clamping mechanism;

[0095] At least two splicing rods are axially spliced ​​together using a threaded joint and a threaded groove to form an operating rod;

[0096] One end of the assembled operating rod is threadedly connected to the mating sleeve of the drive mechanism, and the other end is connected to the threaded joint of the clamping mechanism.

[0097] The servo motor of the drive mechanism is controlled by a Bluetooth remote control handle to drive the operating lever to adjust the angle, so that the insulating cover body moves to the installation position of the voltage transformer.

[0098] After the insulating cover body is fitted onto the voltage transformer, the control drive mechanism drives the operating lever to rotate at a set angle, so that the limit fork disengages from the insulating cover body based on the rotation of the damped double-headed rotating shaft.

[0099] The support mechanism's insert rods are inserted into the ground or contact the paved ground through threaded connectors to achieve stable support for the box-shaped backpack.

[0100] The angle adjustment process includes reducing the output speed of the servo motor by a speed reducer, so that the docking sleeve drives the operating lever to adjust the pitch angle.

[0101] The operating lever has a rotation angle range of 30°-60°, and the rotation direction is consistent with the release direction of the insulating cover body.

[0102] When deploying the support mechanism, the tip of the insert rod can be inserted into soft ground or the flat end of the threaded connector can be brought into contact with hardened ground.

[0103] When operating in complex terrain, the insulating cover body is positioned and installed directly by manually assembling a control rod.

[0104] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
