Description

Technical Field

[0001] The invention relates to the field of electric power maintenance, and in particular to a tank type circuit breaker sleeve disassembly and assembly safety belt suspension device and a use method thereof. Background Art

[0002] During the maintenance and overhaul of the power system, the disassembly and assembly of the bushing of the tank circuit breaker is a critical and complex task. As the core equipment in the power system, the stability and safety of the tank circuit breaker are crucial to the operation of the entire power grid. Traditional bushing disassembly and assembly work usually needs to be carried out at high altitudes, and the safety risks of the operators are relatively high. In existing technologies, operators often need to build scaffolding around the bushing or use other temporary support structures to carry out high-altitude operations. These structures are not only cumbersome and time-consuming to build and dismantle, but may also pose additional safety threats to operators during the operation. In addition, most of the existing suspension devices are simple in design and cannot provide sufficient stability and safety. Especially when faced with bushings of different specifications and positions, it is difficult to adapt and fix, resulting in low operating efficiency.

[0003] In view of the above problems, some patents have proposed solutions. For example, the existing patent CN217612570U is mainly designed for tank circuit breakers of 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 realizes stable suspension of the safety belt through the design of the suspension rod and the mounting ring, as well as the adjustable first crossbar and the second crossbar. Although the device improves the safety and stability of the operation to a certain extent, in actual application, its installation and adjustment process may still be relatively complicated, and for the ectopically arranged sleeve, its locking and fixing mechanism needs to be further optimized.

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

[0067] The present invention can stably fix to the outer circumference of casings of different specifications through the first fixing mechanism and the second fixing mechanism, providing a stable working platform for operators. At the same time, the design of the rotating connecting piece and the central column enables the device to adapt to casings of different positions and angles, greatly improving the safety of high-altitude operations.

[0068] The suspension device of the present invention is compact in design and easy to operate. It does not require the construction of scaffolding or other temporary support structures, and the operator can quickly enter the working state, thereby significantly improving the working efficiency. Through the rotation connection design of the first connecting arm and the second connecting arm, the present invention can flexibly adapt to casings of different specifications and positions, especially in casings arranged in different positions, and can also provide a stable suspension point, thereby enhancing the adaptability and flexibility of the device.

[0069] The locking mechanism of the present invention is simple in design. The sliding rod and operating rod provided at the bottom of the central column realize the functions of quick locking and unlocking, simplify the operation process, and improve the convenience and safety of the operation. By adopting high-strength materials and optimized structural design, the suspension device of the present invention has high stability and durability, can maintain performance in various harsh working environments, and reduces the frequency of maintenance and replacement. The design of the suspension device of the present invention allows operators to quickly complete the installation and fixation of the device, greatly reducing the preparation time before the operation and improving the overall work efficiency.

[0070] The present invention uses a first fixing mechanism and a second fixing mechanism, so that the device can be stably fixed on the sleeve at different positions, reducing the safety risks of operators when working at height. The arc-shaped fixed connection part and the rotating fastening part provide a larger contact area and a stronger fastening force, ensuring the stability of the device in various environments. The rotating connection allows the first connecting arm and the second connecting arm to rotate to adapt to sleeves at different angles. The design of multiple groups of grooves at different angles allows the device to be quickly adjusted to a suitable locking position, improving the adaptability and flexibility of the device. The locking mechanism makes the locking and unlocking process more intuitive and simple through the design of the sliding rod and the operating rod. This design reduces the operating difficulty of operators and improves work efficiency.

[0071] The rotating connection between the top platform and the center column, as well as multiple evenly distributed safety belt hanging points, allow operators to quickly find a suitable hanging position, reducing job preparation time.

[0072] The locking mechanism includes an angle detection unit and a control unit, which realizes 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 of the working environment through monitoring cameras and environmental sensor groups, which helps to promptly detect and deal with potential safety issues. The telescopic column design, combined with the telescopic locking mechanism, allows operators to accurately adjust the height of the center column as needed, ensuring the precise positioning and use of the device. The unlocking mechanism, especially the design of the unlocking control unit and the unlocking drive mechanism, makes the unlocking process more automated and convenient, improving the continuity and efficiency of the operation. The positioning device and data recording unit provide real-time location information and historical data records for the operation, which helps to monitor and manage the operation.

[0073] Through the comprehensive application of the above-mentioned technical features, the suspension device of the present invention can ensure the stability and safety of the operators when disassembling and assembling the casing, thereby improving the quality of the operation and reducing the accident rate.

[0074] The present invention reduces the labor intensity of operators in high-altitude operations through automated and intelligent design, and also reduces the cost of long-term maintenance and replacement due to the high stability and durability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0080] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0081] Example 1

[0082] like Figure 1 and Figure 2 As shown, a tank type circuit breaker sleeve disassembly and assembly safety belt suspension device comprises:

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

[0084] The first end of the first connecting arm 1 is provided with a first fixing mechanism 3, and the first fixing mechanism 3 is used to be sleeved and fixed on the outer periphery of the first sleeve; the first end of the second connecting arm 2 is provided with a second fixing mechanism 4, and the second fixing mechanism 4 is used to be sleeved and fixed on 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 connecting member 5, and the second end of the second connecting arm 2 is rotatably connected to the second end of the rotating connecting member 5. A center column 6 is arranged on the top of the rotating connecting member 5; a top platform 7 is arranged on the top of the center column 6, and a safety belt hanging point 8 is arranged on the top platform 7; a locking mechanism is arranged at the bottom of the center column 6, which is used to lock the rotation angles of the first connecting arm 1 and the second connecting arm 2, and fix the position of the center column 6 at the same time.

[0086] Specifically, the connection assembly consists of two main parts, namely a first connecting arm 1 and a second connecting arm 2, which are used to connect with the two bushings of the tank circuit breaker. The first fixing mechanism 3 is arranged at the first end of the first connecting arm 1, and is designed to be sleeved and fixed to the outer periphery of the first bushing. This fixing mechanism includes one or more fasteners, such as fastening bolts or snaps, allowing the device to be tightly fixed on the bushing to ensure stability and safety during operation. The second fixing mechanism 4 is similar to the first fixing mechanism 3, and is arranged at the first end of the second connecting arm 2, and is used to be sleeved and fixed 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 connecting member 5 through a rotating mechanism, allowing the first connecting arm 1 to rotate relative to the rotating connecting member 5. Similarly, the second end of the second connecting arm 2 is also connected to the second end of the rotating connecting member 5 through a similar rotating 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 center column 6 is provided at the top of the rotating connector 5, and the center column 6 extends upward from the rotating connector 5 to form the main support structure of the suspension device. The design of the center column 6 should ensure sufficient strength and stability to support the weight of the top platform 7 and the operator when using the safety belt. A top platform 7 is provided on the top of the center column 6, which provides a suspension point for the safety belt for the operator. The top platform 7 can be designed as a plane or a structure with a certain shape to adapt to different operating requirements and improve the comfort of the operator. One or more safety belt suspension points 8 are provided on the top platform 7, which are used to directly connect the safety belt of the operator. The design of the suspension point should ensure that it can safely bear the weight of the operator and can be easily and quickly released 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, and fix the position of the central column 6. The locking mechanism may include but is not limited to a locking pin, a locking nut or other mechanical locking devices. The design of the mechanism should allow the device to be locked by simple operation after it is installed in place, so as to ensure the stability of the device during operation.

[0090] Through the combination of the above structures, the suspension device of the present invention can provide a safe, stable and easy-to-operate aerial work platform for the disassembly and assembly of the tank type circuit breaker casing. The design of the device takes into account the needs of different working environments. By setting the rotating connector 5 and the locking mechanism, the device can adapt to casings in different positions and angles, while ensuring the safety of operators during aerial work.

[0091] Example 2

[0092] As a preferred example, the second end of the first connecting arm 1 and the second end of the second connecting arm 2 are arranged inside the rotating connecting member 5, and the second end surface of the first connecting arm 1 and the second end surface of the second connecting arm 2 are respectively correspondingly provided with multiple groups of grooves 11 with different angles in a ring shape, and the locking mechanism includes a sliding rod 10 arranged at the bottom center of the central column 6 and an operating rod 9 connected to the top of the sliding rod 10, and a sliding groove is vertically arranged on the bottom side of the central column 6, and the operating rod 9 is slidably arranged in the sliding groove, and the sliding rod 10 is used to insert into the groove 11 after the first connecting arm 1 and the second connecting arm 2 are fixed, and the first connecting arm 1 and the second connecting arm 2 are locked at the same time, and 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 end of the first connecting arm 1 and the second end of the second connecting arm 2 are designed to be arranged inside the rotating connecting member 5. This layout allows the connecting arms to be rotated and locked inside the rotating connecting member 5, thereby reducing external interference and improving the overall stability of the device. On the second end surface of the first connecting arm 1 and the second end surface of the second connecting arm 2, multiple groups of grooves 11 with different angles are respectively arranged in an annular manner. These grooves 11 are used to cooperate with the slide bar 10 in the locking mechanism to achieve locking at different angles to adapt to the sleeves in different positions and operation requirements.

[0094] The locking mechanism includes a slide bar 10 disposed at the center of the bottom of the center column 6, and an operating rod 9 connected to the top of the slide bar 10. The design of the slide bar 10 and the operating rod 9 allows the operator to control the movement of the slide bar 10 through the operating rod 9, thereby locking the connecting arm. A slide groove is vertically arranged on the side of the bottom of the center column 6, and the operating rod 9 is slidably arranged in the slide groove. The design of the slide groove allows the operating rod 9 to slide in the vertical direction so that the slide bar 10 can be inserted into the corresponding groove 11 on the end surface of the connecting arm.

[0095] After the first connecting arm 1 and the second connecting arm 2 are fixed at the desired position, the slide bar 10 is pushed by the operating rod 9 and inserted into the groove 11 on the end surface 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. The top and bottom of the slide are respectively provided with locking parts, which are used to lock the position of the operating rod 9 to ensure that the operating rod 9 will not move accidentally after the locking operation is completed, thereby ensuring the stability of the locked state.

[0096] Through the detailed description of the above structure and operation steps, a specific implementation method is provided, which enables the locking mechanism of the tank circuit breaker sleeve disassembly and assembly safety belt suspension device to be flexibly and stably locked on the sleeve at different angles, and at the same time provides a simple and effective locking and unlocking mechanism. This implementation method not only improves the adaptability and operation convenience of the device, but also enhances the safety and reliability during the operation process.

[0097] Example 3

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

[0099] Specifically, the rotational connection between the top platform 7 and the center column 6 is achieved through one or more bearings, which may be ball bearings, roller bearings or other types of bearings to ensure that the top platform 7 can rotate smoothly and flexibly around the center column 6. This design allows the top platform 7 to be adjusted according to the position requirements of different operators, thereby improving the flexibility and comfort of the operation. The top platform 7 can be designed to be round, square or other suitable shapes to adapt to different working environments and space requirements. The material of the platform should be strong enough to bear the weight of the operator and the safety belt, and it also needs to have anti-slip properties to ensure the safety of the operator. There are multiple safety belt suspension points 8 evenly distributed on the top platform 7, which may be fixed rings, hooks or other forms of fixing devices. The design and layout of the suspension points are intended to ensure that the operator can easily hook and remove the safety belt, while also ensuring the stability and reliability of the safety belt during the operation.

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

[0101] When using the device, the operator first fixes the first fixing mechanism 3 and the second fixing mechanism 4 on the two sleeves of the tank circuit breaker respectively, and then adjusts the top platform 7 to a suitable position and angle by rotating the connecting member 5. Then, the operator can hang the safety belt on any safety belt hanging point 8 on the top platform 7. After the operation is completed, the operator can easily disassemble the device by removing the safety belt and adjusting the position of the top platform 7.

[0102] The top platform 7 of the tank circuit breaker casing disassembly and assembly safety belt suspension device can be flexibly rotated, and multiple evenly distributed safety belt suspension points 8 are provided to meet 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 the operation.

[0103] Example 4

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

[0105] The working state determination unit may be specifically a microprocessor control module, which is arranged on the top or inside of the central column 6 and is used to monitor the power connection, circuit integrity and functional status of key components of the device. When the device completes initialization and reaches the working ready state, the unit sends a working state signal through an LED indicator or a digital display screen to indicate to the operator that the device is ready for locking operation; the working state determination unit may also be a set of electronic password locks, which can enter or leave the working state only when the correct password is entered, to prevent accidental touch during operation.

[0106] The locking sensing unit may be specifically a set of Hall effect sensors, which are 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, the corresponding Hall effect sensor is triggered, which then sends a locking signal to the control unit, indicating that the fixing mechanism is securely locked.

[0107] The angle detection unit can be a high-precision electronic gyroscope installed inside the central column 6 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 to provide the control unit with accurate angle information.

[0108] The control unit may be specifically an integrated electronic control board that receives signals from the angle detection unit, the working state determination unit, and the locking sensing unit. The control unit determines whether the three locking conditions of the vertical position, the locking state, and the working state are met at the same time through a built-in logic judgment program. When all conditions are met, the control unit sends a locking instruction to the execution unit.

[0109] The execution unit may include an electric push rod as a driving mechanism and a movable locking pin. One end of the electric push rod 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 push rod responds to the command, pushes the locking pin to move in the center column 6, and inserts it into the locking groove at the end of the first connecting arm 1 and the second connecting arm 2 to achieve locking. When unlocking, the electric push rod operates in the reverse direction to pull the locking pin out of the locking groove.

[0110] The locking groove can be a set of annular grooves, which are arranged 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 in the central column 6 to ensure that the locking pin can be accurately inserted into and lock the connecting arm.

[0111] The manual release device may be specifically an emergency stop button with a protective cover, which is arranged at a position that is easily accessible to the operator. In an emergency or when maintenance is required, the operator can open the protective cover and press the button to send an unlocking command to the control unit, so that the locking pin is disengaged from the locking slot to achieve quick unlocking.

[0112] The locking mechanism is ensured to be automatically locked when the center column reaches the vertical position and the fixing mechanism is fully locked, ensuring stability and safety during operation. At the same time, the manual release device provides an emergency unlocking means, which enhances the flexibility and safety of the device. This implementation not only improves the safety and reliability of the device, but also improves the operating efficiency by accurately controlling the locking process.

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

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

[0116] A rotating fastening portion, wherein the rotating fastening portion is arc-shaped, a first end of the rotating fastening portion is rotatably connected to a second end of the fixed connection portion, and the second end of the rotating fastening portion is used to be adjustably connected to the first end of the fixed connection portion, and is used to adjust the space area formed by the rotating fastening portion and the fixed connection portion;

[0117] The first end of the fixed connection part is also provided with a ratchet fastening mechanism for connecting with the second end of the rotating fastening part to prevent the rotating fastening part from being separated;

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

[0119] Specifically, the fixed connection part is designed to be arc-shaped to adapt to the circular periphery of the sleeve. The first end of the fixed connection part is fixedly connected to the rotating connection assembly, which can be achieved by welding, bolt connection or other appropriate fixing methods. The arc design helps to increase the contact area between the fixed connection part and the sleeve and enhance the fixing effect. The rotating fastening part is also designed to be arc-shaped 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 through a rotating mechanism, allowing a certain angle of rotation to adapt to sleeves of different diameters. The second end of the rotating fastening part is connected to the first end of the fixed connection part by an adjustable connection method, such as by a thread, a buckle or other fasteners, to adjust the space area between the rotating fastening part and the fixed connection part, so as to achieve the fastening of sleeves of different sizes. The first end of the fixed connection part is also provided 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 paddle matched with the ratchet. By operating the paddle, the ratchet can be engaged or disengaged, thereby achieving the locking and unlocking of the rotating fastening part. The unlocking mechanism is arranged at the first end of the fixed connection part, and is used to unlock the locking of the second end of the rotating fastening part by the ratchet fastening mechanism. The unlocking mechanism may include an unlocking lever or a similar operating component. By manually operating the unlocking lever, the paddle of the ratchet fastening mechanism can be driven to disengage the ratchet from the meshing state, thereby unlocking the rotating fastening part.

[0120] When using the device, first fix the fixed connection parts of the first fixing mechanism 3 and the second fixing mechanism 4 to the two bushings of the tank circuit breaker. Then, adjust the position of the rotating fastening part according to the diameter of the bushing so that it forms a suitable space area with the fixed connection part to achieve fastening. By operating the unlocking mechanism, the rotating fastening part 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 tank circuit breaker sleeve disassembly and assembly safety belt suspension device can adapt to sleeves of different sizes, and provide a simple and effective locking and unlocking mechanism. This embodiment not only improves the adaptability and operation convenience of the device, but also enhances the safety and reliability during the operation.

[0122] Example 6

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

[0124] Specifically, the central column 6 is designed as a telescopic column, including a plurality of column sections that are mutually sleeved, and these column sections can slide relative to each other through a telescopic mechanism, thereby adjusting the total height of the central column 6. The design of the telescopic column allows the device to adapt to the operation requirements of different heights and provides greater flexibility. A telescopic locking mechanism is provided on the telescopic column, which includes two main parts: a locking device and an adjusting device. The locking device is used to fix the current height of the telescopic column to prevent sliding during operation. The adjusting device is used to operate the telescopic action of the telescopic column to adjust to the required height. The locking device may include a locking pin, a locking nut or other locking elements, which can apply a locking force on any column section of the telescopic column to ensure that the telescopic column remains stable after being adjusted to the appropriate height. The locking device is usually arranged at the lower part of the telescopic column for easy operation. The adjusting device may include a manual or electric drive mechanism, such as a screw rod, a hydraulic cylinder or a cylinder, for pushing the column sections of the telescopic column to telescope. The operating end of the adjusting device can be designed as a knob, a handle or a button to facilitate the operator to adjust the height.

[0125] According to the specific conditions of the work site, the operator drives the telescopic column section to extend and 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 to ensure that it will not slide or collapse during the operation. After the operation is completed, the operator can release the height lock of the telescopic column by unlocking the locking device, and then retract the telescopic column to a state that is convenient for transportation and storage through the adjustment device.

[0126] The center column 6 of the tank circuit breaker sleeve disassembly and assembly safety belt suspension device can flexibly adjust the height, and ensure the stability and safety during the operation through the telescopic locking mechanism. This embodiment improves the applicability and operation convenience of the device, and also enhances the flexibility and efficiency of the operation.

[0132] The unlocking element includes an unlocking lever having a first end connected to the unlocking drive mechanism and a second end for interacting with the ratchet fastening mechanism;

[0133] The unlocking drive mechanism includes a motor and a transmission member for converting the rotational motion of the motor into the linear motion of the unlocking rod;

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

[0135] Specifically, the unlocking control unit is arranged on the inner side of the fixed connection part, and specifically can be a control panel or a button for receiving the unlocking instruction from the operator. The control unit can include one or more sensors, such as a pressure sensor or a touch sensor, to detect the unlocking request of the operator. The unlocking drive mechanism is connected to the unlocking control unit, and 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. The mechanism is designed to provide sufficient power to drive the unlocking element to ensure the smooth progress of the unlocking process. The unlocking element is operated by the unlocking drive mechanism, and is used to interact with the ratchet fastening mechanism to release the locked state of the rotating fastening part. The unlocking element specifically includes an unlocking rod, the first end of which is connected to the unlocking drive mechanism, and the second end is used to directly interact with the ratchet fastening mechanism. As a part of the unlocking element, the unlocking rod is designed to allow contact with a specific part of the ratchet fastening mechanism to achieve the unlocking function. The unlocking rod can be a straight rod or a rod with a certain degree of curvature to adapt to the interaction with the ratchet fastening mechanism. The unlocking drive mechanism includes a motor and a transmission member, such as a gear, a chain, a belt or a screw, for converting the rotational motion of the motor into the linear motion of the unlocking rod. The selection and design of the transmission parts should ensure effective power transmission and smooth movement. The unlocking mechanism is designed to automatically reset after completing the unlocking action. This can be achieved through a spring-loaded mechanism, gravity or an additional reset drive mechanism to ensure that the unlocking mechanism can return to its initial position after each use and is ready for the next operation.

[0136] The operator issues an unlock command through the unlock control unit. After 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 to push the ratchet out of the locked position. The locked state of the rotating fastening part is released, allowing the device to be adjusted or disassembled as necessary. After the unlocking is completed, the unlocking mechanism returns to the initial state through the automatic reset function, ready for the next operation.

[0137] Example 8

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

[0139] A positioning sensor, installed on the top of the top platform 7, for capturing the position coordinates of the suspension device in space;

[0140] A signal processing module, connected to the positioning sensor, for processing the signal captured by the positioning sensor and converting it into position data;

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

[0142] Specifically, the positioning sensor is the core component of the positioning device and is installed on the top of the top platform 7. The sensor can be a global positioning system (GPS) sensor, an inertial measurement unit (IMU), or other types of sensors for capturing the position coordinates of the suspension device in space in real time. The design of the sensor should ensure that it can provide accurate position information under various environmental conditions. The signal processing module is connected to the positioning sensor and is responsible for processing the raw signal captured by the sensor. The signal processing module may include electronic components such as filters, amplifiers, analog-to-digital converters (ADCs) for converting sensor signals into digital signals and performing necessary signal processing such as noise filtering, signal amplification, and data formatting to generate accurate positioning data. The data transmission module is used to transmit the position data generated by the signal processing module to a remote monitoring system or a data processing center. The module may include wireless communication components such as Wi-Fi, Bluetooth, cellular networks (such as 4G or 5G) or other wireless communication technologies to achieve remote transmission of data. The data transmission module should also include necessary network protocol support to ensure that data can be transmitted safely and reliably.

[0143] After the suspension device is installed and fixed to the tank circuit breaker casing, the positioning sensor starts working and captures the spatial position coordinates of the device in real time. The signal processing module receives the sensor signal, processes it, and generates formatted position data. The data transmission module sends the processed position data to the remote monitoring system or data processing center through the wireless communication network. In the remote monitoring system or data processing center, the received position data can be used to monitor the status of the device in real time, perform data analysis, or be used for subsequent maintenance and operation decisions. The top platform 7 of the tank circuit breaker casing disassembly and assembly safety belt suspension device can be equipped with a precise positioning device. This embodiment not only improves the positioning accuracy and monitoring capability of the device, but also enhances the real-time control of the operating status of the device, which helps to improve the safety and efficiency of the operation.

[0144] Example 9

[0145] As a preferred example, a work monitoring device is provided on the top of the top platform 7, including:

[0146] A monitoring camera, installed on the top of the top platform 7, for capturing visual images of the working area in real time;

[0147] An image processing unit receives the image captured by the monitoring camera and processes the image to identify the action of the operator and the state of the working environment;

[0148] An environmental sensor group, including a temperature sensor, a humidity sensor, and a light sensor, is used to monitor environmental parameters in the working environment;

[0149] A 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 operator meet the safety regulations;

[0150] An alarm system, which is used to send out an alarm signal to alert operators or ground control personnel when the data analysis unit detects an abnormal situation;

[0151] The data recording unit is used to record the images captured by the monitoring camera and the data monitored by the environmental sensor group for subsequent analysis and audit.

[0152] Specifically, the monitoring camera is installed on the top of the top platform 7 to capture the visual image of the working area in real time. The camera can be a high-definition camera with night vision function and wide dynamic range to adapt to different lighting conditions and environments. The image processing unit receives the image captured by the monitoring camera and processes the image to identify the action of the operator and the state of the working environment. The unit may include one or more processors to run image recognition algorithms such as motion detection, face recognition and behavior analysis. The environmental sensor group includes a temperature sensor, a humidity sensor and a light sensor to monitor environmental parameters in the working environment. These sensors can measure the ambient temperature, humidity and light intensity in real time and transmit the data to the data analysis unit. The data analysis unit receives the data from the image processing unit and the environmental sensor group and analyzes whether the working environment and the behavior of the operator meet the safety specifications. The data analysis unit may include one or more computers to run data analysis software to evaluate the safety of the working area. The alarm system is used to send an alarm signal to remind the operator or ground control personnel when the data analysis unit detects an abnormal situation. The alarm system may include an audible and visual alarm, a vibration alarm or other types of alarm devices to ensure that relevant personnel can be notified in time in an emergency. The data recording unit is used to record images captured by the surveillance camera and data monitored by the environmental sensor group for later analysis and audit. The data recording unit may include a storage device, such as a hard disk drive or solid-state drive, and a data management system for storing, retrieving and analyzing the recorded data.

[0153] The monitoring camera starts working and captures the visual image of the working area in real time. The image processing unit receives the image data and processes it in real time to identify the actions of the operators and the state of the working environment. The environmental sensor group monitors the environmental parameters in the working environment 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 group to evaluate the safety of the working area. If the data analysis unit detects an abnormal situation, the alarm system will immediately send out an alarm signal to remind the operator or ground control personnel to take corresponding measures. The data recording unit records the images captured by the monitoring camera and the data monitored by the environmental sensor group for subsequent analysis and auditing. The top platform 7 of the tank-type circuit breaker casing disassembly and assembly safety belt suspension device can be equipped with a complete work monitoring device. Not only does it improve the monitoring capability of the working area, but it also enhances the real-time analysis and early warning of the working environment and operator behavior, which helps to improve the safety and efficiency of the operation.

[0154] Example 10

[0155] like Figure 3 As shown, a method for using a tank type circuit breaker sleeve disassembly and assembly safety belt suspension device comprises the following steps:

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

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

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

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

[0160] The safety belt is hung on the safety belt hanging point 8 provided on the top platform 7.

[0161] Specifically, the fixing mechanism is installed: the operator sleeves and fixes the first fixing mechanism 3 and the second fixing mechanism 4 on the outer periphery of the first sleeve and the second sleeve of the tank circuit breaker respectively. This step involves adapting the arc design of the fixing connection part to the outer periphery of the corresponding sleeve, and achieving tight fixation with the sleeve by rotating the fastening part.

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

[0163] Through the locking mechanism, the operator locks the rotation angle of the first connecting arm 1 and the second connecting arm 2, and fixes the position of the center column 6. This may involve using an angle detection unit and a control unit to determine the exact position of the center column 6, and then achieving locking through an execution unit, such as a locking pin and a driving mechanism.

[0164] To adjust the telescopic column, the operator adjusts the height of the telescopic column and locks the height through the telescopic locking mechanism to meet the needs of different working heights.

[0165] The operator starts the work monitoring device, including the monitoring camera and the environmental sensor group, to monitor the working area and environmental status in real time. At the same time, ensure that the positioning device is activated to capture the position coordinates of the device in space.

[0166] The operator hangs the safety belt on the safety belt suspension points 8 provided on the top platform 7. These suspension points are evenly distributed on the top platform 7 to ensure that the operator can safely hang the safety belt.

[0167] During the 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 abnormal situation, such as environmental parameters exceeding the preset safety threshold, the alarm system will sound an alarm to remind the operator 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 group for post-analysis and auditing.

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

[0170] Embodiment 11

[0171] The operator starts the device through the operation panel or remote control. After the working status determination unit receives the start signal, it sends a working status signal to the control unit through the 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 sleeve and the second sleeve of the tank circuit breaker respectively, and manually or electrically makes the clamping arms of the fixing mechanism tightly sleeve the outer circumference of the sleeve to ensure that there is no looseness between the fixing mechanism and the sleeve.

[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 position change of the magnet and then sends a locking signal to the control unit, indicating that the fixing mechanism is firmly locked.

[0174] Precise adjustment of the center column: The operator rotates the center column 6 by rotating the handle or operating the electric actuator, and 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 the 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 sends a locking command to the execution unit.

[0176] Execute the locking action: After the execution unit receives the locking command, the electric push rod or the hydraulic drive mechanism pushes the locking pin to move along the guide rail of the center column 6 until the locking pin is fully inserted into the locking grooves of the first connecting arm 1 and the second connecting arm 2, thereby locking the connecting arms.

[0177] Activation of the positioning device: The positioning device is activated after the working state determination unit sends a working state signal, and 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 to realize real-time positioning and monitoring of the suspension device.

[0178] Start of work monitoring: The work monitoring device starts after the device enters the working state. The monitoring camera starts to capture the visual image of the working area, and the environmental sensor group (including temperature, humidity and light sensors) monitors the environmental parameters in the working environment. The data analysis unit analyzes the data from the monitoring camera and the environmental sensor group to ensure that the working environment and the behavior of the operators meet the safety regulations. If the data analysis unit detects any abnormal situation, the alarm system will immediately send out an alarm signal to remind the operator or ground control personnel to take corresponding measures.

[0179] Suspension of the safety belt: The operator suspends the safety belt at the safety belt suspension point 8 provided on the top platform 7, ensuring that the safety belt is properly suspended and can be used safely. Under the monitoring of the monitoring device, the operator can start the disassembly and assembly of the tank circuit breaker casing.

[0180] Data recording: The data recording unit records the images captured by the surveillance camera and the data monitored by the environmental sensor group during the entire operation process for post-analysis and auditing to ensure the traceability of the operation process.

[0181] Completion and unlocking of the operation: After the operation is completed, the operator sets the working state determination unit to a non-working state through the operation panel or remote control. The manual release device (such as an emergency stop button) is activated, and the automatic locking command of the control unit is manually released to unlock the locking mechanism. The unlocking mechanism (such as an electric push rod or a hydraulic drive mechanism) pushes the locking pin out of the locking groove to unlock 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 through the unlocking mechanism, the operator can easily remove the suspension device and complete the entire disassembly and assembly process.

[0183] Through the above specific implementation, the present invention provides a detailed method for using a tank type circuit breaker casing disassembly and assembly safety belt suspension device, which ensures the safety of high-altitude operations and the stability of the device, while achieving rapid locking and unlocking, and improving the work efficiency. Each step is closely linked to ensure the correct installation and safe use of the device, as well as rapid unlocking and removal.
