Description

Technical Field

[0001] This invention relates to the field of power maintenance, specifically to a safety belt suspension device for disassembling and assembling a tank-type circuit breaker bushing and its usage method. Background Technology

[0002] In the maintenance and repair of power systems, the installation and removal of bushings for tank-type circuit breakers is a critical yet complex task. As a core piece of equipment in the power system, the stability and safety of tank-type circuit breakers are crucial to the operation of the entire power grid. Traditional bushing installation and removal work typically requires working at heights, posing significant safety risks to workers. With existing technology, workers often need to erect scaffolding or use other temporary support structures around the bushings for high-altitude operations. These structures are not only cumbersome and time-consuming to set up and dismantle, but may also pose additional safety threats to workers during the operation. Furthermore, most existing suspension devices are simply designed and cannot provide sufficient stability and safety, especially when dealing with bushings of different sizes and locations, making them difficult to adapt to and secure, resulting in low work efficiency.

[0003] To address the aforementioned issues, several patents have proposed solutions. For example, the existing patent CN217612570U mainly targets the design of tank-type circuit breakers for specific voltage levels, and its adaptability and flexibility for bushings of different sizes and shapes still need to be improved.

[0004] Another existing patent, CN117695553A, achieves stable suspension of the safety belt through the design of the boom and mounting ring, as well as adjustable first and second crossbars. Although this device improves the safety and stability of operations to some extent, its installation and adjustment process may still be relatively complex in practical applications, and its locking and fixing mechanism needs further optimization for sleeves installed in different positions.

[0005] Therefore, there is an urgent need for a new type of safety belt suspension device for disassembling and assembling tank-type circuit breakers to address the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a safety belt suspension device and method for installing and removing bushings of tank-type circuit breakers, in order to solve the problems of high safety risks, low work efficiency and poor device adaptability in the prior art.

[0029] Optionally, the unlocking mechanism includes,

[0030] An unlocking control unit is located inside the fixed connection part and is used to receive unlocking signals from the operator;

[0031] An unlocking drive mechanism, connected to the unlocking control unit, is used to respond to the unlocking signal and perform an unlocking action;

[0032] The unlocking element, operated by the unlocking drive mechanism, interacts with the ratchet fastening mechanism to release the locked state of the rotating fastening part;

[0033] The unlocking element includes an unlocking rod, the first end of which is connected to the unlocking drive mechanism, and the second end of which is used to interact with the ratchet fastening mechanism.

[0034] The unlocking drive mechanism includes a motor and a transmission component, used to convert the rotational motion of the motor into the linear motion of the unlocking lever;

[0040] Optionally, a work monitoring device is installed on the top of the top platform, including:

[0041] A surveillance camera, installed on top of the top platform, is used to capture visual images of the work area in real time;

[0042] The image processing unit receives images captured by the surveillance camera and processes the images to identify the actions of the workers and the state of the working environment.

[0043] An environmental sensor array, including temperature, humidity, and light sensors, is used to monitor environmental parameters in the work environment.

[0044] The data analysis unit receives data from the image processing unit and the environmental sensor group, and analyzes whether the working environment and the behavior of the workers comply with safety regulations.

[0045] An alarm system is provided to issue an alarm signal to alert operators or ground control personnel when the data analysis unit detects an anomaly.

[0046] The data recording unit is used to record the images captured by the surveillance camera and the data monitored by the environmental sensor group for post-event analysis and auditing.

[0047] A method for using a safety belt suspension device for installing and removing bushings of a tank-type circuit breaker includes the following steps:

[0048] The first fixing mechanism is sleeved and fixed to the outer periphery of the first bushing of the tank-type circuit breaker;

[0049] The second fixing mechanism is sleeved and fixed to the outer periphery of the second bushing of the tank-type circuit breaker;

[0052] The seat belt is suspended from the seat belt suspension point set on the top platform.

[0053] Optionally, the following steps may also be included:

[0054] The working status determination unit is set to the working status, and the working status determination unit sends a working status signal to the control unit;

[0055] The first fixing mechanism and the second fixing mechanism are respectively sleeved and fixed to the outer periphery of the first bushing and the second bushing of the tank-type circuit breaker.

[0056] The locking sensing unit detects whether the first and second fixing mechanisms are fully locked, and sends a locking signal to the control unit when it detects that they are fully locked.

[0057] Rotating the central column causes the rotating connector to rotate. The angle detection unit detects the rotation angle of the central column relative to the vertical direction in real time and sends the angle data to the control unit.

[0058] When the control unit detects that the central column has rotated to the vertical position and receives the locking signal from the locking sensing unit and the working status signal from the working status determination unit, the control unit sends a locking command to the execution unit.

[0059] The execution unit receives a locking command and drives the locking pin to insert into the locking slot through the drive mechanism to lock the first connecting arm and the second connecting arm.

[0060] The positioning device is activated, the positioning sensor captures the position coordinates of the suspension device in space, the signal processing module processes the signal and converts it into position data, and the data transmission module transmits the position data to the remote monitoring system or data processing center.

[0061] The work monitoring device is activated, the monitoring camera begins to capture visual images of the work area, the environmental sensor group monitors environmental parameters in the work environment, and the data analysis unit analyzes the data to determine whether the work environment and the behavior of the workers comply with safety regulations.

[0062] The safety belt is suspended from the safety belt suspension point set on the top platform, and the operation is carried out under the monitoring of the monitoring device.

[0063] The data logging unit is activated to record images captured by surveillance cameras and data monitored by environmental sensor arrays for post-event analysis and auditing.

[0064] After the operation is completed, the working status determination unit is set to the non-working state, and the automatic locking command of the control unit is released manually through the manual release device to unlock the locking mechanism;

[0065] The first and second fixing mechanisms are unlocked using the unlocking mechanism, thus completing the dismantling process.

[0066] Compared with the prior art, the present invention has the following beneficial effects:

[0067] This invention, through a first fixing mechanism and a second fixing mechanism, can stably fix itself to the outer circumference of sleeves of different specifications, providing workers with a stable working platform. Simultaneously, the design of the rotating connector and the central column allows the device to adapt to sleeves at different positions and angles, greatly improving the safety of high-altitude operations.

[0068] The suspension device of this invention is compact in design and easy to operate. It requires no scaffolding or other temporary support structures, allowing workers to quickly get to work, thus significantly improving work efficiency. Through the rotating connection design of the first and second connecting arms, this invention can flexibly adapt to sleeves of different specifications and positions. Especially in sleeves with displaced installations, it can provide a stable suspension point, enhancing the adaptability and flexibility of the device.

[0069] The locking mechanism of this invention features a simple design. Through a sliding rod and operating lever located at the bottom of the central column, it achieves rapid locking and unlocking, simplifying the operation process and improving convenience and safety. By employing high-strength materials and an optimized structural design, the suspension device of this invention exhibits high stability and durability, maintaining performance in various harsh working environments and reducing the frequency of maintenance and replacement. The suspension device design of this invention allows operators to quickly complete the installation and fixation of the device, significantly reducing preparation time before operation and improving overall work efficiency.

[0070] This invention, through a first and a second fixing mechanism, allows the device to be stably fixed to sleeves at different positions, reducing safety risks for workers operating at heights. The arc-shaped fixing connection and rotating fastening part provide a larger contact area and stronger fastening force, ensuring the stability of the device in various environments. The rotating connector allows the first and second connecting arms to rotate to accommodate sleeves at different angles, and the multiple sets of grooves at different angles allow the device to be quickly adjusted to a suitable locking position, improving its adaptability and flexibility. The locking mechanism, through the design of a sliding rod and an operating lever, makes the locking and unlocking process more intuitive and simple. This design reduces the operational difficulty for workers and improves work efficiency.

[0071] The rotating connection between the top platform and the central column, along with the evenly distributed multiple safety belt suspension points, allows workers to quickly find suitable suspension positions, reducing preparation time.

[0072] The locking mechanism includes an angle detection unit and a control unit, enabling real-time monitoring and automatic locking of the center column position, reducing the possibility of human error. The work monitoring device provides real-time data on the working environment through monitoring cameras and environmental sensor arrays, helping to promptly identify and address potential safety issues. The telescopic column design, combined with the telescopic locking mechanism, allows operators to precisely adjust the height of the center column as needed, ensuring accurate positioning and use of the device. The unlocking mechanism, particularly the unlocking control unit and unlocking drive mechanism, makes the unlocking process more automated and convenient, improving the continuity and efficiency of operations. The positioning device and data recording unit provide real-time location information and historical data records for the operation, aiding in operation monitoring and management.

[0073] By comprehensively applying the above-mentioned technical features, the suspension device of the present invention can ensure the stability and safety of operators when installing and removing sleeves, thereby improving the quality of work and reducing the accident rate.

[0074] This invention reduces the labor intensity of workers in high-altitude operations through automated and intelligent design. At the same time, the high stability and durability of the device also reduce the cost of long-term maintenance and replacement. Attached Figure Description

[0079] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0080] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0081] Example 1

[0082] like Figure 1 and Figure 2 As shown, a safety belt suspension device for installing and removing bushings of a tank-type circuit breaker includes,

[0083] A connecting assembly for connecting to the bushing of a tank-type circuit breaker, comprising a first connecting arm 1 and a second connecting arm 2;

[0084] The first connecting arm 1 is provided with a first fixing mechanism 3 at its first end, which is used to be sleeved and fixed to the outer periphery of the first sleeve; the second connecting arm 2 is provided with a second fixing mechanism 4 at its first end, which is used to be sleeved and fixed to the outer periphery of the second sleeve.

[0085] The second end of the first connecting arm 1 is rotatably connected to the first end of the rotating connector 5, and the second end of the second connecting arm 2 is rotatably connected to the second end of the rotating connector 5. A central column 6 is provided at the top of the rotating connector 5. A top platform 7 is provided at the top of the central column 6, and a safety belt suspension point 8 is provided at the top platform 7. A locking mechanism is provided at the bottom of the central column 6 to lock the rotation angle of the first connecting arm 1 and the second connecting arm 2, and at the same time fix the position of the central column 6.

[0086] Specifically, the connecting assembly consists of two main parts: a first connecting arm 1 and a second connecting arm 2, for connecting to the two bushings of the tank-type circuit breaker. A first fixing mechanism 3 is located at the first end of the first connecting arm 1 and is designed to fit and secure to the outer periphery of the first bushing. This fixing mechanism includes one or more fasteners, such as fastening bolts or clips, allowing the device to be securely fixed to the bushing, ensuring stability and safety during operation. A second fixing mechanism 4, similar to the first fixing mechanism 3, is located at the first end of the second connecting arm 2 and is used to fit and secure to the outer periphery of the second bushing. This fixing mechanism also includes fasteners to achieve the same stability and safety as the first fixing mechanism 3.

[0087] The second end of the first connecting arm 1 is connected to the first end of the rotating connector 5 via a rotation mechanism, allowing the first connecting arm 1 to rotate relative to the rotating connector 5. Similarly, the second end of the second connecting arm 2 is connected to the second end of the rotating connector 5 via a similar rotation mechanism, allowing the second connecting arm 2 to rotate. This design enables the suspension device to adapt to sleeves at different angles or positions, increasing the flexibility and applicability of the device.

[0088] A central column 6 is located at the top of the rotating connector 5, extending upwards to form the main support structure of the suspension device. The design of the central column 6 should ensure sufficient strength and stability to support the weight of the top platform 7 and the worker using the safety belt. The top platform 7, located at the top of the central column 6, provides the worker with a suspension point for the safety belt. The top platform 7 can be designed as a flat surface or a structure with a specific shape to accommodate different operational needs and improve worker comfort. One or more safety belt suspension points 8 are provided on the top platform 7 for direct connection to the worker's safety belt. The suspension points should be designed to safely support the worker's weight and allow for easy and quick release in an emergency.

[0089] The locking mechanism is located at the bottom of the central column 6 and is used to lock the rotation angle of the first connecting arm 1 and the second connecting arm 2, while simultaneously fixing the position of the central column 6. The locking mechanism may include, but is not limited to, locking pins, locking nuts, or other mechanical locking devices. The design of this mechanism should allow for easy locking through simple operation after the device is installed in place, ensuring the stability of the device during operation.

[0090] Through the combination of the above structures, the suspension device of the present invention provides a safe, stable, and easy-to-operate high-altitude work platform for the installation and removal of bushings for tank-type circuit breakers. The device is designed with the needs of different working environments in mind. By using the rotating connector 5 and the locking mechanism, the device can adapt to bushings at different positions and angles, while ensuring the safety of workers when working at height.

[0091] Example 2

[0092] As a preferred example, the second ends of the first connecting arm 1 and the second connecting arm 2 are disposed inside the rotating connector 5. The end faces of the second ends of the first connecting arm 1 and the second connecting arm 2 are respectively provided with a plurality of grooves 11 at different angles in a ring. The locking mechanism includes a slide rod 10 disposed at the bottom center of the central column 6 and an operating rod 9 connected to the top of the slide rod 10. A sliding groove is vertically disposed on the bottom side of the central column 6. The operating rod 9 is slidably disposed in the sliding groove. The slide rod 10 is used to insert into the groove 11 after the first connecting arm 1 and the second connecting arm 2 are fixed, thereby locking the first connecting arm 1 and the second connecting arm 2. The top and bottom of the sliding groove are respectively provided with locking parts for locking the position of the operating rod 9.

[0093] Specifically, the second ends of the first connecting arm 1 and the second ends of the second connecting arm 2 are designed to be located inside the rotating connector 5. This layout allows the connecting arms to rotate and lock within the rotating connector 5, thereby reducing external interference and improving the overall stability of the device. Multiple sets of grooves 11 at different angles are respectively arranged in a ring on the second end faces of the first connecting arm 1 and the second connecting arm 2. These grooves 11 are used to cooperate with the slide bar 10 in the locking mechanism to achieve locking at different angles, adapting to different sleeve positions and operational requirements.

[0094] The locking mechanism includes a slide bar 10 located at the center of the bottom of the central column 6, and an operating lever 9 connected to the top of the slide bar 10. The design of the slide bar 10 and the operating lever 9 allows the operator to control the movement of the slide bar 10 via the operating lever 9, thereby locking the connecting arm. A vertical groove is provided on the bottom side of the central column 6, within which the operating lever 9 slides. The groove design allows the operating lever 9 to slide vertically, so that the slide bar 10 can be inserted into a corresponding groove 11 on the end face of the connecting arm.

[0095] After the first connecting arm 1 and the second connecting arm 2 are fixed in the desired positions, the slide bar 10 is pushed by the operating lever 9 and inserted into the groove 11 on the end face of the corresponding connecting arm, thereby locking the rotation angle of the two connecting arms. This locking method ensures the stability and safety of the device during operation. Locking parts are provided at the top and bottom of the slide groove, which are used to lock the position of the operating lever 9, ensuring that the operating lever 9 will not move accidentally after the locking operation is completed, thus guaranteeing the stability of the locked state.

[0096] The detailed description of the structure and operation steps above provides a specific implementation method that enables the locking mechanism of the bushing suspension device for installing and removing tank-type circuit breakers to flexibly and stably lock onto bushings at different angles, while also providing a simple and effective locking and unlocking mechanism. This implementation method not only improves the adaptability and ease of operation of the device, but also enhances the safety and reliability during operation.

[0097] Example 3

[0098] As a preferred example, the top platform 7 is rotatably connected to the central column 6, and multiple seat belt suspension points 8 are provided and evenly distributed on the top platform 7.

[0099] Specifically, the rotational connection between the top platform 7 and the central column 6 is achieved through one or more bearings, which can be ball bearings, roller bearings, or other types of bearings, to ensure that the top platform 7 can rotate smoothly and flexibly around the central column 6. This design allows the top platform 7 to be adjusted according to the positional needs of different workers, thereby improving operational flexibility and comfort. The top platform 7 can be designed as circular, square, or other suitable shapes to adapt to different working environments and space requirements. The platform material should be strong enough to withstand the weight of the workers and safety belts, while also possessing anti-slip properties to ensure worker safety. Multiple safety belt suspension points 8 are evenly distributed on the top platform 7. These suspension points can be fixing rings, hooks, or other forms of fixing devices. The design and layout of the suspension points are designed to ensure that workers can easily attach and detach their safety belts, while also ensuring the stability and reliability of the safety belts during operation.

[0100] The safety belt suspension points 8 are evenly distributed on the top platform 7, meaning that the positional relationship between the suspension points is symmetrical or arranged according to a certain geometric pattern to ensure that each suspension point can provide stable support when the top platform 7 rotates. The evenly distributed suspension points also help to distribute the pressure on the device caused by the activities of workers on the platform, thereby improving the durability of the device.

[0101] When using this device, the operator first secures the first fixing mechanism 3 and the second fixing mechanism 4 to the two bushings of the tank-type circuit breaker, respectively. Then, the operator adjusts the top platform 7 to a suitable position and angle by rotating the connecting piece 5. Next, the operator can attach the safety belt to any of the safety belt suspension points 8 on the top platform 7. After the work is completed, the operator can easily disassemble the device by unfastening the safety belt and adjusting the position of the top platform 7.

[0102] The top platform 7 of the safety belt suspension device for installing and removing the bushing of the tank-type circuit breaker can rotate flexibly and provides multiple evenly distributed safety belt suspension points 8 to adapt to the needs of different operators and working environments. This implementation not only improves the practicality and safety of the device, but also enhances the comfort and convenience during operation.

[0103] Example 4

[0104] As a preferred example, the locking mechanism includes:

[0105] The working status determination unit can be a microprocessor control module, located on top of or inside the central column 6, used to monitor the device's power connection, circuit integrity, and the functional status of key components. When the device completes initialization and reaches the working ready state, this unit emits a working status signal via an LED indicator or digital display, instructing the operator that the device is ready for locking. The working status determination unit can also be an electronic combination lock, requiring the correct password to enter or exit the working state, preventing accidental activation during operation.

[0106] The locking sensing unit can specifically be a set of Hall effect sensors, respectively installed near the locking mechanisms of the first fixing mechanism 3 and the second fixing mechanism 4. When the ratchet in the locking mechanism is engaged, it triggers the corresponding Hall effect sensor, which then sends a locking signal to the control unit, indicating that the fixing mechanism has been securely locked.

[0107] The angle detection unit can specifically be a high-precision electronic gyroscope, installed inside the central column 6, used to measure and output the angle change of the central column relative to the vertical direction in real time. The data output of the gyroscope is connected to the control unit, providing the control unit with accurate angle information.

[0108] The control unit can be an integrated electronic control board that receives signals from the angle detection unit, the working status determination unit, and the locking sensing unit. The control unit uses a built-in logic program to determine whether the three locking conditions—vertical position, locked state, and working state—are simultaneously met. When all conditions are met, the control unit sends a locking command to the execution unit.

[0109] The actuator may include an electric actuator as a drive mechanism and a movable locking pin. One end of the electric actuator is connected to the locking pin, and the other end is connected to the control unit. When the control unit issues a locking command, the electric actuator responds to the command, pushing the locking pin to move within the central column 6 and insert it into the locking groove at the end of the first connecting arm 1 and the second connecting arm 2, thereby achieving locking. For unlocking, the electric actuator reverses its operation, pulling the locking pin out of the locking groove.

[0110] The locking groove can be a set of annular grooves, located on the inner side of the ends of the first connecting arm 1 and the second connecting arm 2. These grooves match the size of the locking pin inside the central post 6, ensuring that the locking pin can be accurately inserted and lock the connecting arm.

[0111] The manual release device can be a protective cover-mounted emergency stop button located in an easily accessible position for the operator. In an emergency or for maintenance purposes, the operator can open the protective cover and press the button to send an unlocking command to the control unit, causing the locking pin to disengage from the locking slot and achieving rapid unlocking.

[0112] This design ensures that the locking mechanism automatically locks when the central column reaches a vertical position and the fixing mechanism is fully locked, guaranteeing stability and safety during operation. Simultaneously, a manual release device provides an emergency unlocking method, enhancing the flexibility and safety of the device. This implementation not only improves the safety and reliability of the device but also increases operational efficiency through precise control of the locking process.

[0113] Example 5

[0114] As a preferred example, the first fixing mechanism 3 and the second fixing mechanism 4 respectively include:

[0115] A fixed connection part, wherein the fixed connection part is arc-shaped, and the first end of the fixed connection part is fixedly connected to the rotating connection assembly;

[0116] A rotating fastening part is provided, wherein the rotating fastening part is arc-shaped, and the first end of the rotating fastening part is rotatably connected to the second end of the fixed connection part. The second end of the rotating fastening part is used to adjustably connect to the first end of the fixed connection part, thereby adjusting the spatial area formed by the rotating fastening part and the fixed connection part.

[0117] The first end of the fixed connection part is also provided with a ratchet fastening mechanism, which is used to connect the second end of the rotating fastening part to prevent the rotating fastening part from disengaging.

[0118] An unlocking mechanism is provided at the first end of the fixed connection portion and is used to unlock the ratchet fastening mechanism from locking the second end of the rotating fastening portion.

[0119] Specifically, the fixed connection part is designed in an arc shape to accommodate the circular outer circumference of the sleeve. The first end of the fixed connection part is fixedly connected to the rotating connection assembly, which can be achieved through welding, bolting, or other suitable fixing methods. The arc shape helps increase the contact area between the fixed connection part and the sleeve, enhancing the fixing effect. The rotating fastening part is also designed in an arc shape to match the fixed connection part. The first end of the rotating fastening part is connected to the second end of the fixed connection part via a rotating mechanism, allowing for rotation at a certain angle to accommodate sleeves of different diameters. The second end of the rotating fastening part is connected to the first end of the fixed connection part via an adjustable connection method, such as through threads, snaps, or other fasteners, to adjust the space between the rotating fastening part and the fixed connection part, achieving fastening of sleeves of different sizes. The first end of the fixed connection part is also equipped with a ratchet fastening mechanism, which is used to lock the second end of the rotating fastening part to prevent it from disengaging during operation. The ratchet fastening mechanism may include a ratchet and a lever that engages with the ratchet. By operating the lever, the ratchet can be engaged or disengaged, thereby locking and unlocking the rotating fastening part. An unlocking mechanism is located at the first end of the fixed connection portion and is used to unlock the ratchet fastening mechanism from locking the second end of the rotating fastening portion. The unlocking mechanism may include an unlocking lever or a similar operating component. By manually operating the unlocking lever, the lever of the ratchet fastening mechanism can be driven to disengage the ratchet, thereby unlocking the rotating fastening portion.

[0120] When using this device, firstly, fix the fixing connection parts of the first fixing mechanism 3 and the second fixing mechanism 4 to the two bushings of the tank-type circuit breaker. Then, adjust the position of the rotating fastener according to the diameter of the bushing to form a suitable space area with the fixing connection part to achieve fastening. By operating the unlocking mechanism, the rotating fastener can be unlocked so that the device can be disassembled after the operation is completed.

[0121] The first fixing mechanism 3 and the second fixing mechanism 4 of the safety belt suspension device for installing and removing bushings of tank-type circuit breakers can adapt to bushings of different sizes, while providing a simple and effective locking and unlocking mechanism. This implementation not only improves the adaptability and ease of operation of the device, but also enhances the safety and reliability during operation.

[0122] Example 6

[0123] As a preferred example, the central column 6 is a telescopic column, and the telescopic column is provided with a telescopic locking mechanism for locking the height of the telescopic column.

[0124] Specifically, the central column 6 is designed as a telescopic column, comprising multiple interlocking column segments. These segments can slide relative to each other via a telescopic mechanism, thereby adjusting the overall height of the central column 6. The telescopic column design allows the device to adapt to different height operating requirements, providing greater flexibility. The telescopic column is equipped with a telescopic locking mechanism, which consists of two main parts: a locking device and an adjusting device. The locking device is used to fix the current height of the telescopic column, preventing slippage during operation. The adjusting device is used to operate the telescopic column's extension and retraction to adjust to the desired height. The locking device may include a locking pin, locking nut, or other locking element that can apply a locking force to any segment of the telescopic column, ensuring stability after adjustment to the appropriate height. The locking device is typically located at the bottom of the telescopic column for easy operation. The adjusting device may include a manual or electric drive mechanism, such as a screw, hydraulic cylinder, or pneumatic cylinder, for actuating the column segments. The operating end of the adjusting device can be designed as a knob, handle, or button for easy height adjustment by the operator.

[0125] According to the specific conditions of the work site, the operator drives the telescopic column to extend or retract by rotating the operating end of the adjustment device until the required working height is reached. After the telescopic column reaches the appropriate height, the operator operates the locking device to lock the telescopic column in the current position, ensuring that it will not slip or collapse during operation. After the work is completed, the operator can release the height lock by unlocking the locking device, and then use the adjustment device to retract the telescopic column to a state that is convenient for transportation and storage.

[0126] The central column 6 of the safety belt suspension device for installing and removing bushings of tank-type circuit breakers can be flexibly adjusted in height, and a telescopic locking mechanism ensures stability and safety during operation. This implementation improves the applicability and ease of operation of the device, while also enhancing operational flexibility and efficiency.

[0131] The unlocking element, operated by the unlocking drive mechanism, interacts with the ratchet fastening mechanism to release the locked state of the rotating fastening part;

[0132] The unlocking element includes an unlocking rod, the first end of which is connected to the unlocking drive mechanism, and the second end of which is used to interact with the ratchet fastening mechanism.

[0133] The unlocking drive mechanism includes a motor and a transmission component, used to convert the rotational motion of the motor into the linear motion of the unlocking lever;

[0134] The unlocking mechanism is used to automatically reset after the unlocking action is completed.

[0135] Specifically, the unlocking control unit is located inside the fixed connection part and can be a control panel or button for receiving unlocking commands from the operator. The control unit may include one or more sensors, such as pressure sensors or touch sensors, to detect the operator's unlocking request. The unlocking drive mechanism, connected to the unlocking control unit, can be an electric motor or other power source, for responding to the unlocking signal received by the control unit and performing the unlocking action. This mechanism is designed to provide sufficient power to drive the unlocking element, ensuring a smooth unlocking process. The unlocking element, operated by the unlocking drive mechanism, interacts with the ratchet fastening mechanism to release the locked state of the rotating fastening part. The unlocking element specifically includes an unlocking lever, with one end connected to the unlocking drive mechanism and the second end for direct interaction with the ratchet fastening mechanism. As part of the unlocking element, the unlocking lever is designed to contact specific parts of the ratchet fastening mechanism to achieve the unlocking function. The unlocking lever can be a straight lever or a lever with a certain degree of curvature to accommodate interaction with the ratchet fastening mechanism. The unlocking drive mechanism includes a motor and transmission components, such as gears, chains, belts, or screws, for converting the rotational motion of the motor into linear motion of the unlocking lever. The selection and design of transmission components should ensure efficient power transmission and smooth movement. The unlocking mechanism is designed to automatically reset after the unlocking action is completed. This can be achieved through a spring-loaded mechanism, gravity, or an additional reset drive mechanism, ensuring that the unlocking mechanism returns to its initial position after each use, ready for the next operation.

[0136] The operator issues an unlock command through the unlock control unit. Upon receiving the command, the unlock control unit activates the unlock drive mechanism. The unlock drive mechanism responds and drives the unlock lever to move, interacting with the ratchet fastening mechanism and pushing the ratchet out of its locked position. The locked state of the rotating fastener is released, allowing the device to be adjusted or disassembled as necessary. After unlocking, the unlock mechanism returns to its initial state via an automatic reset function, ready for the next operation.

[0137] Example 8

[0138] As a preferred example, the top platform 7 is provided with a positioning device, including:

[0139] A positioning sensor, installed on the top of the top platform 7, is used to capture the position coordinates of the suspension device in space;

[0140] A signal processing module, connected to the positioning sensor, is used to process the signals captured by the positioning sensor and convert them into location data;

[0141] The data transmission module is used to transmit the location data of the signal processing module to a remote monitoring system or data processing center.

[0142] Specifically, the positioning sensor, the core component of the positioning device, is mounted on the top of the top platform 7. This sensor can be a Global Positioning System (GPS) sensor, an Inertial Measurement Unit (IMU), or other types of sensors, used to capture the real-time position coordinates of the suspension device in space. The sensor is designed to provide accurate position information under various environmental conditions. A signal processing module, connected to the positioning sensor, is responsible for processing the raw signals captured by the sensor. The signal processing module may include electronic components such as filters, amplifiers, and analog-to-digital converters (ADCs) to convert the sensor signals into digital signals and perform necessary signal processing, such as noise filtering, signal amplification, and data formatting, to generate accurate positioning data. A data transmission module is used to transmit the position data generated by the signal processing module to a remote monitoring system or data processing center. This module may include wireless communication components such as Wi-Fi, Bluetooth, cellular networks (such as 4G or 5G), or other wireless communication technologies to enable remote data transmission. The data transmission module should also include necessary network protocol support to ensure secure and reliable data transmission.

[0143] After the suspension device is installed and secured to the bushing of the tank-type circuit breaker, the positioning sensor begins operation, capturing the spatial coordinates of the device in real time. The signal processing module receives the sensor signals, processes them, and generates formatted position data. The data transmission module sends the processed position data to a remote monitoring system or data processing center via a wireless communication network. At the remote monitoring system or data processing center, the received position data can be used for real-time monitoring of the device's status, data analysis, or for subsequent maintenance and operational decisions. The top platform 7 of the tank-type circuit breaker bushing installation and removal safety belt suspension device can be equipped with a precise positioning device. This implementation not only improves the device's positioning accuracy and monitoring capabilities but also enhances real-time control over the device's operational status, contributing to improved operational safety and efficiency.

[0144] Example 9

[0145] As a preferred example, the top platform 7 is equipped with a work monitoring device, including:

[0146] A surveillance camera, installed on top of the top platform 7, is used to capture visual images of the work area in real time;

[0147] The image processing unit receives images captured by the surveillance camera and processes the images to identify the actions of the workers and the state of the working environment.

[0148] An environmental sensor array, including temperature, humidity, and light sensors, is used to monitor environmental parameters in the work environment.

[0149] The data analysis unit receives data from the image processing unit and the environmental sensor group, and analyzes whether the working environment and the behavior of the workers comply with safety regulations.

[0150] An alarm system is provided to issue an alarm signal to alert operators or ground control personnel when the data analysis unit detects an anomaly.

[0151] The data recording unit is used to record the images captured by the surveillance camera and the data monitored by the environmental sensor group for post-event analysis and auditing.

[0152] Specifically, surveillance cameras are installed on the top of the top platform 7 to capture real-time visual images of the work area. The cameras can be high-definition cameras with night vision capabilities and a wide dynamic range to adapt to different lighting conditions and environments. An image processing unit receives the images captured by the surveillance cameras and processes them to identify worker movements and the state of the work environment. This unit may include one or more processors running image recognition algorithms such as motion detection, facial recognition, and behavior analysis. An environmental sensor array, including temperature, humidity, and light sensors, monitors environmental parameters in the work environment. These sensors can measure ambient temperature, humidity, and light intensity in real time and transmit the data to the data analysis unit. The data analysis unit receives data from the image processing unit and the environmental sensor array and analyzes whether the work environment and worker behavior comply with safety regulations. The data analysis unit may include one or more computers running data analysis software to assess the safety of the work area. An alarm system is used to issue alarm signals when the data analysis unit detects abnormalities, alerting workers or ground control personnel. The alarm system may include audible and visual alarms, vibration alarms, or other types of alarm devices to ensure timely notification of relevant personnel in emergencies. The data logging unit is used to record images captured by surveillance cameras and data monitored by environmental sensor arrays for subsequent analysis and auditing. The data logging unit may include storage devices, such as hard disk drives or solid-state drives, and a data management system for storing, retrieving, and analyzing the recorded data.

[0153] The surveillance camera begins operation, capturing real-time visual images of the work area. The image processing unit receives the image data and processes it in real time to identify worker actions and the state of the work environment. An environmental sensor array monitors environmental parameters and transmits the data to the data analysis unit. The data analysis unit analyzes the data provided by the image processing unit and the environmental sensor array to assess the safety of the work area. If the data analysis unit detects an anomaly, the alarm system immediately issues an alarm signal, alerting workers or ground control personnel to take appropriate measures. The data recording unit records the images captured by the surveillance camera and the data monitored by the environmental sensor array for post-event analysis and auditing. The top platform 7 of the tank-type circuit breaker bushing installation and removal safety belt suspension device can be equipped with a complete work monitoring system. This not only improves the monitoring capabilities of the work area but also enhances real-time analysis and early warning of the work environment and worker behavior, contributing to improved work safety and efficiency.

[0154] Example 10

[0155] like Figure 3 As shown, a method for using a safety belt suspension device for installing and removing bushings of a tank-type circuit breaker includes the following steps:

[0156] The first fixing mechanism 3 is sleeved and fixed to the outer periphery of the first bushing of the tank-type circuit breaker;

[0157] The second fixing mechanism 4 is sleeved and fixed to the outer periphery of the second bushing of the tank-type circuit breaker;

[0158] Rotate the central column 6 to drive the rotating connector 5 to rotate until the central column 6 rotates to the preset position;

[0159] The rotation angles of the first connecting arm 1 and the second connecting arm 2 are locked by the locking mechanism at the bottom of the central column 6, while the position of the central column 6 is fixed.

[0160] The seat belt is suspended at the seat belt suspension point 8 set on the top platform 7.

[0161] Specifically, the installation and fixing mechanism involves the operator fitting the first fixing mechanism 3 and the second fixing mechanism 4 onto the outer periphery of the first and second bushings of the tank-type circuit breaker, respectively. This step involves adapting the arc-shaped design of the fixing connection to the outer periphery of the corresponding bushing and achieving a tight fixation with the bushing by adjusting the rotation of the fastening part.

[0162] Adjusting the rotating connector 5: The operator rotates the central column 6, causing the rotating connector 5 to rotate until the central column 6 reaches the preset position. In this step, multiple sets of grooves 11 at different angles may be used to ensure that the rotating connector 5 can be precisely adjusted to the required angle.

[0163] The operator locks the rotation angles of the first connecting arm 1 and the second connecting arm 2 using a locking mechanism, while simultaneously fixing the position of the central column 6. This may involve using an angle detection unit and a control unit to determine the precise position of the central column 6, and then achieving locking via an actuator, such as a locking pin and a drive mechanism.

[0164] The operator adjusts the height of the telescopic column and locks it using the telescopic locking mechanism to accommodate different working height requirements.

[0165] The monitoring device is set up, and the operator activates it, including a surveillance camera and environmental sensor array, to monitor the work area and environmental conditions in real time. Simultaneously, ensure the positioning device is activated to capture the device's position coordinates in space.

[0166] The operator suspends the safety belt at the safety belt suspension points 8 set on the top platform 7. These suspension points are evenly distributed on the top platform 7 to ensure that the operator can safely attach the safety belt.

[0167] During operation, the operator monitors the output of the data analysis unit and any alarms from the alarm system. If the data analysis unit detects an anomaly, such as environmental parameters exceeding preset safety thresholds, the alarm system will issue an alert to remind the operators or ground control personnel to take appropriate measures.

[0168] The operator ensures that the data logging unit is recording images captured by the surveillance cameras and data monitored by the environmental sensor array for post-event analysis and auditing.

[0169] After the operation is completed, the operator sends an unlocking signal through the unlocking mechanism, including the unlocking control unit and the unlocking drive mechanism, to unlock the rotating fastener, and then disassembles the first fixing mechanism 3 and the second fixing mechanism 4 to complete the removal of the suspension device.

[0170] Example 11

[0171] The operator starts the device via the control panel or remote control. After receiving the start signal, the working status determination unit sends a working status signal to the control unit through its internal circuit. The LED indicator lights up to indicate that the device has entered the working state.

[0172] The operator moves the first fixing mechanism 3 and the second fixing mechanism 4 to the predetermined positions of the first bushing and the second bushing of the tank-type circuit breaker, respectively, and uses manual or electric means to tightly engage the clamping arm of the fixing mechanism with the outer circumference of the bushing to ensure that there is no looseness between the fixing mechanism and the bushing.

[0173] Automatic detection of locking status: The locking sensing unit monitors the locking status of the fixing mechanism in real time. When the clamping arm of the fixing mechanism is fully closed and locks the sleeve, the Hall effect sensor senses the change in the position of the magnet and then sends a locking signal to the control unit, indicating that the fixing mechanism has been firmly locked.

[0174] Precise adjustment of the center column: The operator rotates the center column 6 by turning the handle or operating the electric actuator. The angle detection unit (such as an electronic gyroscope) monitors the rotation angle of the center column in real time and transmits the data to the control unit. The control unit determines whether the center column has reached or is close to the vertical position based on the angle data.

[0175] Automatic triggering of locking command: When the control unit receives the vertical position signal of the center column, the locking signal of the locking sensing unit and the working status signal of the working status determination unit, it confirms that all conditions meet the locking requirements and then issues a locking command to the execution unit.

[0176] Execute the locking action: After receiving the locking command, the execution unit pushes the locking pin along the guide rail of the central column 6 until the locking pin is fully inserted into the locking groove of the first connecting arm 1 and the second connecting arm 2, thereby locking the connecting arm.

[0177] Activation of the positioning device: The positioning device is activated after the working status determination unit sends a working status signal. The positioning sensor (such as GPS or laser rangefinder) begins to capture the position coordinates of the suspension device in space. The signal processing module processes the captured signal, converts it into position data, and transmits the data to the remote monitoring system or data processing center through the data transmission module, realizing real-time positioning and monitoring of the suspension device.

[0178] Work monitoring activation: The work monitoring device activates after entering operational status. The monitoring cameras begin capturing visual images of the work area, and the environmental sensor array (including temperature, humidity, and light sensors) monitors environmental parameters. The data analysis unit analyzes the data from the monitoring cameras and environmental sensors to ensure that the work environment and personnel behavior comply with safety regulations. If the data analysis unit detects any anomalies, the alarm system will immediately issue an alarm signal, alerting personnel or ground control personnel to take appropriate measures.

[0179] Safety belt suspension: The operator suspends the safety belt from the safety belt suspension point 8 set on the top platform 7, ensuring the safety belt is correctly suspended and safe to use. Under the monitoring of the monitoring device, the operator can begin the disassembly and assembly of the tank-type circuit breaker bushing.

[0180] Data logging: The data logging unit records images captured by surveillance cameras and data monitored by environmental sensor groups throughout the operation, for post-operation analysis and auditing, ensuring the traceability of the operation process.

[0181] Work Completion and Unlocking: After the work is completed, the operator sets the working status determination unit to the non-working state via the control panel or remote control. The manual release device (such as an emergency stop button) is activated, and the operator manually operates the automatic locking command of the control unit to unlock the locking mechanism. The unlocking mechanism (such as an electric push rod or hydraulic drive mechanism) pushes the locking pin out of the locking groove, thereby unlocking the first connecting arm 1 and the second connecting arm 2.

[0182] Removal of the fixing mechanism: By unlocking the first fixing mechanism 3 and the second fixing mechanism 4, the operator can easily remove the suspension device and complete the entire disassembly and assembly process.

[0183] Through the above specific embodiments, the present invention provides a detailed method for using a safety belt suspension device for installing and removing bushings of tank-type circuit breakers, ensuring the safety of high-altitude operations and the stability of the device, while achieving rapid locking and unlocking, thus improving work efficiency. Each step is closely linked, ensuring the correct installation and safe use of the device, as well as rapid unlocking and removal.
