Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire storage, and in particular to a grounding wire storage device for a transformer substation. Background Art

[0002] In the daily operation and maintenance of substations, grounding wires are key safety tools to ensure the safety of workers and prevent accidental operation of energized equipment. However, the storage and management of grounding wires have long faced the following challenges:

[0003] Traditional storage methods are inefficient: Traditional manual winding or simple crank-type storage devices rely on manual operation, which is slow and labor-intensive, seriously affecting work efficiency, especially in frequently used substation scenarios.

[0004] Uneven winding causes cable damage: Manual or simple devices cannot ensure uniform cable winding, which can easily cause local extrusion, deformation or insulation damage of the cable. Long-term use may cause safety hazards such as abnormal grounding resistance and degradation of insulation performance.

[0005] Low space utilization: Traditional storage methods lack effective wiring planning, resulting in a messy accumulation of cables, which takes up a lot of storage space and is not conducive to standardized management of substations.

[0006] The electric device is not intelligent enough: Although the existing electric storage device can realize automatic winding, it lacks intelligent control and cannot dynamically adjust the winding parameters according to the cable length and diameter, resulting in unstable winding effect and uneven wiring.

[0007] Therefore, in response to the above problems, especially in scenarios such as substations, power plants, and distribution rooms, where grounding wires are frequently used and space is limited, it is necessary to effectively solve the problem of storing substation grounding wires.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] This device achieves automatic and uniform winding of the grounding wire through the combination of mechanical transmission and guide mechanisms, solving the problems of uneven winding, cable damage, and low space utilization in traditional storage methods. Its core design includes: a dual-axis linkage structure: through the synchronous drive of the winding roller and ball screw, spiral winding and axial arrangement of the cable are achieved; a guide system: using the precise coordination of the ball screw and ball nut to ensure the uniform distribution of the cable along the axial direction of the winding roller;

[0035] This device is mainly realized through the following structure:

[0036] 1. Base and support structure

[0037] The base provides a stable support platform for the entire storage device. The four corners are vertically provided with slotted columns. The slotted columns not only support and fix other components, but also provide installation locations for connectors. The mounting plate is arranged on the outside of two of the slotted columns and is fixedly connected to the base and the slotted columns, providing an installation foundation for components such as the motor assembly. The side plate is arranged between the two slotted columns and is perpendicular to the mounting plate. Together with the slotted columns, it constitutes the main frame structure of the device. The slotted columns on both sides of the side plate and the two slotted columns opposite to the side plate are respectively connected by connectors, thereby enhancing the structural stability of the entire device.

[0038] 2. Winding roller and its transmission components

[0039] The two connecting members are respectively provided with fixed blocks, and a winding roller is provided between the two fixed blocks. The winding roller is used to wind the grounding wire to realize the storage of the grounding wire. Wire retaining discs are provided on both sides of the winding roller. The wire retaining discs can prevent the grounding wire from slipping off the winding roller during the winding process, ensuring the neatness and stability of the winding. A second gear is provided on one end of the winding roller passing through the wire retaining disc on the side close to the side plate. The second gear is connected to the first gear through a gear belt. The first gear is connected to the output end of the motor assembly. When the motor assembly is working, the winding roller is driven to rotate through the transmission of the first gear, the gear belt and the second gear to realize the winding and storage of the grounding wire.

[0040] 3. Ball screw and its supporting components

[0041] Guide shaft supports are respectively provided on the outer sides of the two slot columns parallel to the mounting plate, and a ball screw is provided between the two guide shaft supports. The ball screw is a mechanical transmission device that converts rotational motion into linear motion, and has the characteristics of high precision and high efficiency. The ball screw near the side plate passes through the guide shaft support and is connected to the second synchronous wheel. The first synchronous wheel is sleeved on one end of the winding roller near the side plate through the fixed block. The first synchronous wheel is connected to the second synchronous wheel through a synchronous belt. The motor assembly drives the first gear to drive the second gear through the gear belt, and then drives the winding roller. When the winding roller rotates, the ball screw is driven to rotate through the transmission of the first synchronous wheel, the synchronous belt and the second synchronous wheel.

[0042] A ball nut is sleeved on the ball screw. The ball nut cooperates with the ball screw to convert the rotational motion of the ball screw into its own linear motion. A threading hole for the grounding wire is opened on the top of the ball nut. After passing through the threading hole, the grounding wire is wound around the winding roller. With the linear motion of the ball nut, the grounding wire is evenly wound on the winding roller, avoiding excessive accumulation of cables at a certain position, thereby ensuring the uniformity of winding, avoiding cable damage, and also improving space utilization.

[0043] The grounding wire storage device for the substation uses a reasonable structural design and the cooperation of the ball screw and the ball nut to achieve uniform winding of the grounding wire on the winding roller. This uniform winding method can not only avoid the cable from being damaged by excessive force at a certain position, thereby extending the service life of the grounding wire, but also make full use of the space of the winding roller, improve space utilization, and make the entire storage device more compact and efficient.

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work shall fall within the scope of protection of the present invention.

[0052] like Figures 1 to 5 As shown, it shows a specific embodiment of the present invention:

[0053] The main structure of the grounding wire storage device for substations is made of aluminum profiles, which has a reliable structure. It can quickly and evenly store grounding wires during on-site storage, bringing convenience to storage and transportation, shortening operation time, and is a practical tool.

[0054] like Figures 1 to 5 As shown, the grounding wire storage device for a substation disclosed in the present invention includes a base 1, and groove columns 14 are vertically provided at the four corners of the base 1. A mounting plate 2 and a side plate 3 are also vertically provided on the base 1. The mounting plate 2 is arranged on the outside of two of the groove columns 14 and fixedly connected to the base 1 and the groove columns 14. The side plate 3 is arranged between the two groove columns 14 and is perpendicular to the mounting plate 2. The groove columns 14 on both sides of the side plate 3 and the two groove columns 14 opposite to the side plate 3 are respectively connected by connecting members 15;

[0055] A fixing block 13 is provided on each of the two connecting members 15, and a winding roller 5 is provided between the two fixing blocks 13. A wire retaining drum 4 is sleeved on both sides of the winding roller 5. A second gear 8 is sleeved on one end of the winding roller 5 passing through the wire retaining drum 4 on the side close to the side plate 3. The second gear 8 is connected to the first gear 7 through a gear belt 9, and the first gear 7 is connected to the output end of the motor assembly 6;

[0056] The outer sides of the two slot columns 14 parallel to the mounting plate 2 are respectively provided with guide shaft supports 16, and a ball screw 17 is provided between the two guide shaft supports 16, wherein the ball screw 17 close to the side plate 3 passes through the guide shaft support 16 to connect to the second synchronous wheel 11, and the winding roller 5 close to the side plate 3 is provided with a first synchronous wheel 10 at one end through the fixed block 13, and the first synchronous wheel 10 is connected to the second synchronous wheel 11 through a synchronous belt 12, and a ball nut 19 is provided on the ball screw 17, and a threading hole 20 for threading the grounding wire is provided above the ball nut 19.

[0057] Further, such as Figures 1 to 3 As shown,

[0058] The height of the slot column 14 is the same as that of the mounting plate 2 , and the height of the side plate 3 is lower than that of the mounting plate 2 .

[0059] In actual application, considering the functional requirements of the device, there are specific differences in the height designs of the slot column, the mounting plate and the side plate, that is, the height of the slot column is the same as the mounting plate, while the height of the side plate is lower than the height of the mounting plate;

[0060] First, the slotted columns, serving as the fundamental support structure for the entire storage device, are designed to be at the same height as the mounting plate. This ensures that the tension from winding the grounding wire, as well as the device's own weight, is evenly distributed across all support points, effectively improving the device's overall stability. For example, after a large amount of grounding wire is wound around the winding roller, the device will not tilt or wobble due to inconsistent support structure heights, ensuring a safe and reliable storage process.

[0061] Secondly, the design of the side panel height being lower than the mounting panel is mainly based on the consideration that the winding roller should be set above the side panel, so that the operator can more clearly observe the winding condition of the grounding wire, the moving position of the ball nut, etc., and can promptly discover possible abnormal conditions, such as uneven cable winding, stuck ball nut, etc., so that timely measures can be taken to deal with them and ensure the normal operation of the device.

[0062] Furthermore, the design of the side panels being lower than the mounting plate also allows for coordination with other components within the system. For example, when the motor assembly drives the winding roller and the ball screw drives the ball nut, the lower side panels do not interfere with the movement of these components, ensuring smooth transmission between them. This design also provides adequate space for the installation and operation of transmission components such as synchronous belts and gear belts, ensuring the stability and reliability of the transmission system.

[0063] The above design not only ensures the core functions of evenly winding the ground wire, avoiding cable damage, and improving space utilization, but also further improves the device's ease of operation and maintainability, providing a strong guarantee for the safe and stable operation of the substation.

[0064] Further, such as Figures 1 to 3 As shown,

[0065] One end of the winding roller 5 is fixedly installed with an axial end tension sensor through a flange. The motor assembly 6 includes a motor, a power supply, a controller, and a motor driver. The tension sensor transmits the tension signal to the controller through a shielded wire. After receiving the tension signal, the controller calculates the adjustment amount of the winding speed through PID control and sends the control signal to the motor driver. The motor driver adjusts the speed and torque of the motor according to the control signal, and drives the winding roller 5 to achieve variable speed winding and unwinding.

[0066] In substation grounding wire storage devices, a shaft-end tension sensor is mounted on one end of the winding roller via a flange or sleeve. Combined with a motor assembly consisting of a motor, power supply, controller, and motor driver, a closed-loop tension control system is constructed. This system monitors the grounding wire tension in real time during winding and automatically adjusts the winding speed based on tension changes, achieving variable-speed winding and payout. This ensures the grounding wire maintains appropriate tension during the winding process, preventing cable damage and uneven winding caused by excessive or insufficient tension, thereby improving the performance and reliability of the storage device.

[0067] 1. Shaft end tension sensor

[0068] Mounting method: A shaft-mounted tension sensor is fixed to one end of the winding roller via a flange. This flange mounting method offers advantages such as simple structure, secure installation, and easy removal. It ensures a stable connection between the tension sensor and the winding roller, guaranteeing accurate tension measurement.

[0069] Working Principle: When a ground wire is wound around a winding roller, it exerts a certain amount of tension on the roller. This tension is transmitted through the roller to the shaft-end tension sensor. The tension sensor utilizes specialized mechanical structures, such as strain gauges, to convert this tension into an electrical signal.

[0070] 2. Motor assembly

[0071] Motor: The motor is the power source for the entire ground wire collection system, providing the power for the winding rollers to rotate. Depending on your needs, motors with varying power, speed, and torque can be selected to accommodate different ground wire sizes.

[0072] Power supply: The power supply provides electrical energy to components such as the motor, controller, and motor driver, ensuring the normal operation of the entire system. The power supply voltage and current should be appropriately selected based on the power requirements of each component, and appropriate protection devices such as overload protection and short-circuit protection should be installed to ensure system safety and stability.

[0073] Controller: The controller is the core component of the entire tension control system. It receives the tension signal transmitted by the tension sensor and calculates the adjustment amount for winding speed based on a preset control algorithm, such as the PID control algorithm. The controller usually uses a microprocessor or single-chip microcomputer chip, which has strong data processing capabilities and fast response speed.

[0074] Motor Driver: The motor driver adjusts the motor's speed and torque based on control signals from the controller. It converts the controller's digital or analog output into drive signals the motor can recognize, enabling precise control of the motor. The motor driver offers a wide speed regulation range, high speed regulation accuracy, and fast response, meeting the winding roller's speed and torque requirements under varying operating conditions.

[0075] 3. Signal transmission and control process

[0076] Signal Transmission: The tension sensor transmits the measured tension signal to the controller via shielded wires. Shielded wires have excellent anti-interference properties, effectively reducing the impact of external electromagnetic interference on the tension signal, ensuring accurate and stable signal transmission.

[0077] PID Control Calculation: After receiving the tension signal, the controller uses the PID control algorithm. Based on the deviation between the set target tension and the actual measured tension, the PID control algorithm calculates the winding speed adjustment through adjustments in three steps: proportional (P), integral (I), and differential (D). The proportional step quickly responds to deviation changes, the integral step eliminates the system's steady-state errors, and the differential step predicts deviation trends and enables proactive adjustments, enabling the system to quickly and accurately track the set point.

[0078] Control Signal Transmission and Motor Adjustment: The controller sends the calculated control signal to the motor driver, which adjusts the motor speed and torque accordingly. When the measured tension exceeds the target tension, the controller reduces the winding speed, reducing the amount of ground wire wrapped around the wire, thereby lowering the tension. When the measured tension falls below the target tension, the controller increases the winding speed, increasing the amount of ground wire wrapped around the wire, thereby increasing the tension. This closed-loop control method enables variable speed winding and unwinding of the winding roller, ensuring that the ground wire maintains the appropriate tension throughout the winding process.

[0079] The above design has obvious technical advantages:

[0080] 1. Improve storage quality: By real-time monitoring and adjusting the tension of the grounding wire, problems such as cable stretching, deformation, and breakage caused by excessive tension, as well as uneven cable winding and looseness caused by insufficient tension, are avoided, thereby improving the storage quality of the grounding wire.

[0081] 2. Enhance equipment reliability: Reasonable tension control can reduce friction and wear between the ground wire and components such as the winding roller and the wire drum, thereby extending the service life of the equipment and reducing equipment maintenance costs.

[0082] 3. Improve operational safety: Stable tension control can ensure the safety and reliability of the grounding wire during the storage process, avoiding safety accidents caused by loose cables, abnormal winding, etc., and improving the operational safety of the substation.

[0083] 4. Realize automatic control: The tension control system adopts automatic control mode, without manual intervention, and can automatically adjust the winding speed according to actual conditions, thereby improving the automation level and work efficiency of the storage device.

[0084] Further,

[0085] The motor is a servo motor.

[0086] The servo motor has precise control to ensure the storage quality. The servo motor provides real-time feedback of position information through the encoder, and the controller accurately adjusts the speed and direction to make the rotation angle error of the winding roller extremely small, such as within ±0.1°, so that the ground wire is wound evenly, avoiding overlap or excessive gaps, and improving the storage quality.

[0087] The servo motor has a fast dynamic response and can adjust its output within milliseconds to adapt to sudden changes in tension such as cable jams, ensuring stable system operation and avoiding cable damage or equipment failure due to changes in resistance.

[0088] It can still output high torque when running at low speed, for example, the torque reaches 30% of the rated value at 0.1rpm, and there is no creeping phenomenon. It can cope with complex working conditions. When initially winding or encountering resistance, the cable is wound smoothly to avoid strain or uneven winding.

[0089] The servo motor is selected in this device mainly considering the above advantages. The servo motor significantly improves the stability, reliability and automation level of the substation grounding wire storage device through its precise control, rapid response, high efficiency and energy saving characteristics. It has high precision, high efficiency and low maintenance cost.

[0090] Further, such as Figures 1 to 3 As shown,

[0091] A guide shaft 18 is further provided between the two guide shaft supports 16. The guide shaft 18 is provided on the lower side of the ball screw 17. The ball nut 19 includes a nut head and a thread head. A threaded hole is provided on the upper side of the nut head to cooperate with the ball screw 17. An opening is provided on the lower side of the nut head to be sleeved on the guide shaft 18. The nut head moves horizontally under the rotation of the ball screw 17.

[0092] The thread passing head is arranged on the upper side of the nut head. A threading hole 20 is provided on the thread passing head. A circle of cleaning cotton is fixed inside the threading hole 20.

[0093] The above structure can achieve stable and uniform winding of the ground wire on the winding roller, and complete the cleaning of the ground wire during the winding process.

[0094] The guide shaft support supports and secures the guide shaft, providing a stable mounting base for the entire guide system. The guide shaft is located between the two guide shaft supports and beneath the ball screw. It assists in the horizontal movement of the ball nut head and, together with the ball screw, forms a more stable guide system, ensuring that the nut head does not deflect during movement, ensuring smooth and accurate movement.

[0095] A threaded hole that cooperates with the ball screw is opened on the upper side of the nut head, and a threaded transmission relationship is formed with the ball screw through the threaded hole; an opening is opened on the lower side that is sleeved on the guide shaft, so that it can move horizontally along the guide shaft.

[0096] Its working principle: When the ball screw rotates, the nut head moves horizontally due to the threaded fit between the nut head and the ball screw. At the same time, due to the fit between the hole on the underside of the nut head and the guide shaft, the nut head also moves along the guide shaft during movement. This dual guidance makes the movement of the nut head more stable and reliable.

[0097] The wire guide is located above the nut head and features a threading hole. The grounding wire passes through the threading hole and, as the nut head moves horizontally, winds evenly around the winding roller. Furthermore, a loop of cleaning cotton is secured inside the threading hole. This cotton cleans the grounding wire as it winds, removing dust, dirt, and other impurities from its surface to ensure its cleanliness.

[0098] The entire work process is divided into the following stages:

[0099] Initial state: The ground wire passes through the threading hole on the wire head, and the nut head is located at the initial position of the ball screw and guide shaft.

[0100] Movement: When the ground wire needs to be wound, the ball screw begins to rotate. Because the nut head and the ball screw threads mate, the nut head begins to move horizontally as the ball screw rotates. Simultaneously, the opening on the underside of the nut head moves along the guide shaft, ensuring accurate and stable movement of the nut head.

[0101] Winding and Cleaning: As the nut head moves horizontally, the grounding wire is evenly wound around the winding roller under the action of the wire head. During the winding process, the grounding wire passes through the threading hole and comes into contact with the cleaning cotton inside the threading hole. The cleaning cotton cleans the grounding wire and removes impurities on its surface.

[0102] Winding is completed: When the grounding wire is wound to the required length, the ball screw stops rotating, the nut head stops moving, and the grounding wire winding process is completed.

[0103] It has the advantages of stable guidance, uniform winding, and cleanliness, and has obvious effects when used on-site in substations.

[0104] Stable guidance: The dual guidance of ball screw and guide shaft makes the movement of the nut head more stable and accurate, avoiding the movement deviation and shaking that may be caused by a single guidance method, and improving the working reliability of the entire structure.

[0105] Uniform winding: Through the horizontal movement of the nut head, the grounding wire can be evenly wound on the winding roller, avoiding the accumulation or uneven winding of the grounding wire on the winding roller and improving the space utilization of the winding roller.

[0106] Cleaning function: Cleaning cotton is set inside the threading hole of the wire head, which can clean the grounding wire during its winding process, ensuring the cleanliness of the grounding wire, which is beneficial to extend the service life of the grounding wire and improve its electrical performance.

[0107] Further,

[0108] The fixing block 13 is provided with an opening, a bearing is embedded in the opening, and the winding roller 5 is fixed on the inner wall of the inner ring of the bearing.

[0109] The bearing connection setting not only allows for the stable rotation of the winding roller driven by the motor, but also ensures that the fixed block remains stationary, providing a stable support and operating environment for the entire winding system.

[0110] The fixed blocks, located on either side of the winding roller, serve as the fundamental support components of the entire winding system. They provide mounting locations for the winding roller and bearings, ensuring the roller's stability and reliability during rotation. The fixed blocks are provided with openings, the size and shape of which are designed based on the outer diameter and shape of the bearing to ensure the bearing fits securely within the openings. The bearings, embedded within the openings of the fixed blocks, are the key components connecting the fixed blocks to the winding roller. Their function is to withstand the radial and axial loads generated by the winding roller's rotation, while reducing friction between the winding roller and the fixed blocks, enabling smooth rotation of the winding roller. The inner ring of the bearing is fixedly connected to the winding roller, while the outer ring fits tightly within the openings of the fixed block. The rolling elements roll between the inner and outer rings, enabling relative rotation between the two rings.

[0111] The winding roller is fixed to the inner wall of the bearing's inner ring. Driven by a motor, it rotates, evenly winding the ground wire or other cables around the roller, thus storing and organizing the cables. The shape and size of the winding roller are designed according to actual needs. It is usually cylindrical with a smooth surface to facilitate cable winding.

[0112] By embedding bearings in the openings of the fixed block, the winding roller can rotate stably under the drive of the motor, reducing the unstable rotation caused by friction and uneven load, and improving the winding efficiency and quality. At the same time, the fixed block serves as a supporting component and remains stationary under the action of the bearing, providing a stable installation foundation for the winding roller and ensuring the reliability and safety of the entire winding system.

[0113] The winding rollers and bearings of different sizes and shapes can also be replaced according to different on-site winding requirements to adapt to the winding requirements of different cables, thereby improving the versatility and flexibility of the equipment.

[0114] Further, such as Figures 1 to 4 As shown,

[0115] The fixing block 13 is provided with mounting ears at both ends of its bottom, and the connecting piece 15 is provided with a plurality of slots. The fixing block 13 is bolted to the slots on the connecting piece 15 via the mounting ears at both ends.

[0116] The connector features several slots to allow for flexible adjustment of the winding roller's spatial position to accommodate varying on-site winding requirements. Mounting ears are provided at each end of the fixing block's base and bolted to the slots on the connector, allowing the fixing block to be adjusted on the connector, thereby changing the spatial layout of the winding roller.

[0117] During installation, the mounting position of the fixing block on the connector is determined based on the on-site winding requirements. On-site measurement and calculation can be used to determine the optimal connection point between the fixing block and the connector to ensure the winding roller can meet the on-site winding space requirements.

[0118] Further, such as Figures 1-2 As shown,

[0119] The guide shaft support 16 and the slot column 14 are connected by bolts through a plurality of slot holes provided on the slot column 14 .

[0120] The slotted columns feature several slotted holes to allow for the guide shaft support to be adjusted to accommodate various on-site cable winding requirements. The guide shaft support supports and guides the ball screw and guide shaft, ensuring accurate cable routing during winding. The slotted columns serve as a supporting foundation, and the slotted holes allow for the adjustment of the guide shaft support. Bolted together, the guide shaft support can be securely fastened to different locations on the column, allowing the vertical position of the guide shaft to be adjusted to accommodate diverse cable winding scenarios.

[0121] The slotted column is provided with several slotted holes. The spacing and number of slotted holes are designed according to actual needs to meet the installation requirements of the guide shaft support at different heights. The slotted hole design makes the bolt connection more flexible and facilitates the adjustment of the position of the guide shaft support.

[0122] Determine the installation height of the guide shaft support on the slot column based on the on-site winding requirements. Determine the optimal installation point of the guide shaft support on the slot column through measurement and calculation to meet the on-site winding requirements for the guide shaft position.

[0123] In summary, this structure, through the bolted connection between the guide shaft support and the slot column, allows for adjustable position of the guide shaft support on the slot column, providing a flexible solution for on-site winding. Through proper installation and adjustment, it can meet the winding requirements of different scenarios, improving winding efficiency and quality.

[0124] Further, such as Figures 1 to 3 ,5,

[0125] The four corners of the lower side of the base 1 are provided with foot cups 22, and the foot cups 22 are connected to the base 1 through a connecting seat 24. The connecting seat 24 includes a connecting plate and a connecting cap. The foot cup 22 is threadedly connected to the connecting cap. A fixing seat 25 is fixed on the connecting cap, and a caster 23 is provided on the fixing seat 25. The foot cup 22 is also provided with a locking nut connected to the external thread of the connecting cap.

[0126] The base serves as the foundation for the entire device, bearing the weight of the equipment above and various forces during operation. The feet, located at the four corners of the base, support the device and ensure a stable placement. The feet are threaded and can be connected to the connecting cap for height adjustment.

[0127] The connector includes a connecting plate and a connecting cap. The connecting plate secures the connector to the base, while the connecting cap is threadedly connected to the foot cup. The locking nut is connected to the external thread of the connecting cap and is used to lock the foot cup after it is adjusted to the appropriate height, preventing it from loosening or shifting during use.

[0128] The mounting bracket is attached to the connecting cap and is used to mount the caster. The design of the mounting bracket ensures a secure connection between the caster and the connecting cap while facilitating installation and removal of the caster. The caster is mounted on the mounting bracket to enable the device to move.

[0129] Placement status:

[0130] When the device needs to be placed stably, the foot cup is rotated downward from the connecting cap, and the extension length of the foot cup is adjusted by rotating the foot cup to make the device reach a horizontal and stable state.

[0131] After the adjustment is completed, use the locking nut to connect the external thread of the connecting cap to lock the foot cup to prevent it from loosening during use.

[0132] Mobile status:

[0133] When you need to move the device, first loosen the locking nut and screw the foot cup into the connecting cap so that the bottom of the foot cup is higher than the bottom of the caster. At this point, the caster is on the ground and the device can be moved by the caster. During the movement, the direction of the caster can be adjusted as needed to achieve flexible steering.

[0134] The integrated design of the foot cup and caster reduces the space required by separate casters and foot cups, making the device more compact and easier to install in limited spaces. This integrated design simplifies installation: simply secure the connector to the base, thread the foot cup into the connector cap, and finally install the caster and locking nut to complete the installation. The height of the foot cup can be adjusted by rotating it to meet the height requirements of different usage scenarios. The caster is also very easy to install and remove, making it easy to replace or repair as needed. The locking nut ensures the stability of the foot cup during use, preventing it from loosening or shifting. Furthermore, the secure connection between the caster and the mounting base ensures the stability and reliability of the device during movement.

[0135] This design not only improves the flexibility and convenience of the device, but also ensures the stability and reliability of the device during use.

[0136] Further, such as Figures 1 to 3 As shown,

[0137] Handles 21 are provided on both sides of the connecting member 15, and anti-slip grooves are provided on the handles 21;

[0138] Insulating layers are provided on the upper side of the base 1, the inner side of the mounting plate 2, the inner side of the side plate 3, and the wire retaining plate 4;

[0139] An anti-corrosion coating is provided on the lower side of the base 1 , the outer side of the mounting plate 2 , and the outer side of the side plate 3 .

[0140] Handles are located on both sides of the connector, allowing operators to grasp and operate from different directions. The handles are ergonomically designed and conform to the palm of the hand, ensuring a comfortable and secure grip. The handles are secured to the connector using a robust connection, such as welding or bolting, to prevent loosening or falling off during grasping and operation.

[0141] Anti-slip grooves are placed on the handle to increase friction between the operator's hand and the handle, preventing slipping during gripping and operation. The anti-slip grooves can be designed with uneven textures, which increases friction without causing discomfort to the hand.

[0142] At substations, equipment is often installed outdoors, subject to complex and changing environmental conditions such as rain, humidity, high temperatures, and ultraviolet radiation. These environmental factors can not only cause equipment corrosion and shorten its service life, but can also lead to electrical safety issues, such as live ground wires. Therefore, it is particularly important to install insulation barriers and anti-corrosion coatings on key equipment locations.

[0143] Insulation barrier: Prevents the ground wire or other live parts from accidentally coming into contact with the equipment's metal casing or grounding system, thereby avoiding current leakage and the risk of electric shock.

[0144] Anti-corrosion coating: protects the metal surface of the equipment from environmental corrosion, extends the service life of the equipment, and ensures stable operation of the equipment in harsh environments.

[0145] Insulation barrier location

[0146] Upper side of the base: The base serves as the device's support structure, with its upper side in direct contact with the device. An insulating barrier prevents electrical connection between the device and the base, preventing current from being conducted through the base to the ground or other devices.

[0147] Inside the mounting plate: The mounting plate is used to secure and support electrical components within the device. Providing an insulating barrier ensures electrical isolation between the electrical components and the mounting plate, preventing current leakage.

[0148] Inside the side panels: The side panels serve as the equipment's external protective structure, and their inner sides are adjacent to the equipment's internal electrical components. The insulating barrier prevents the side panels from becoming electrically charged due to accidental contact with live components, improving equipment safety.

[0149] Cable reels: Cable reels are used to organize and secure cables. An insulating barrier prevents direct contact between the cables and the reel, preventing current from being conducted through the cables to the reel or other equipment.

[0150] Insulating materials with high insulation resistance and low dielectric loss, such as polytetrafluoroethylene (PTFE) and silicone rubber, can be selected and evenly coated on the surface of the equipment by spraying, brushing or pasting.

[0151] Anti-corrosion coating setting location

[0152] Underside of the base: The underside of the base is in direct contact with the ground and is easily affected by environmental factors such as moisture and rain. Applying an anti-corrosion coating can prevent corrosion of the base.

[0153] Outside of the mounting plate: The outside of the mounting plate is exposed to the outdoor environment and is susceptible to ultraviolet radiation, rain erosion, etc. Providing an anti-corrosion coating can protect the mounting plate from corrosion.

[0154] Outside of the side panels: The outside of the side panels are also exposed to the outdoor environment. Providing an anti-corrosion coating can improve the corrosion resistance of the side panels.

[0155] You can choose coatings with excellent corrosion resistance, such as epoxy resin coatings, polyurethane coatings, etc.

[0156] Improved safety: The design of the insulation barrier and anti-corrosion coating effectively prevents current leakage and equipment corrosion, improving the safety and reliability of the equipment.

[0157] Extended service life: Anti-corrosion coating protects the metal surface of the equipment from environmental corrosion, extending the service life of the equipment.
