Description

Technical Field

[0001] The present invention relates to the technical field of power engineering, and in particular to an auxiliary device for the maintenance and installation of power equipment for smart grids. Background Technique

[0002] The distribution cabinet is a device used to distribute electric energy in the power system. It can reasonably distribute the electric energy from the transformer to each branch circuit. Its main functions include controlling and protecting the circuit. In a power system, it is like a transportation hub, delivering electric energy to different places in an orderly manner. In the power system of a factory, the distribution cabinet can distribute the main power supply to various power-consuming units such as the production lines, lighting systems, and office areas of different workshops. At the same time, it can also monitor parameters such as current and voltage of these branches. When a branch has faults such as overload and short circuit, it can cut off the circuit in time to protect the safety of electrical equipment.

[0003] The patent with the publication number CN220334720U discloses an auxiliary device for the maintenance and installation of power equipment for power engineering, including a bottom plate. Four corners of the top of the bottom plate are fixedly connected with fixed columns. The bottom of the outer surface of the fixed column is fixedly sleeved with a fixed block. The center of the outer surface of the fixed column is slidably sleeved with a support plate. Four corners of the bottom of the support plate are fixedly connected with fixing plates. The corresponding sides of the fixed blocks and the corresponding sides of the fixing plates are fixedly connected with sliding rods. The left and right sides of the outer surface of the sliding rod at the bottom are slidably sleeved with first sliders. This patent has the function of stable lifting through the cooperation of a protective fence, a support plate, a fixed column, a bottom plate, a cylinder, a first slider, a connecting rod, a sliding rod, a second slider, a support seat, and a protective door. When in use, it can lift the staff stably and protect the staff at the same time, preventing the staff from falling from a height and causing safety accidents.

[0004] During the use of the above device, if the distribution cabinet is not convenient for maintenance, maintenance personnel may need to spend a lot of time locating faulty components. In a distribution cabinet with a chaotic layout, the component markings are unclear or there are no markings, and various lines are intertwined. Maintenance personnel have to check each component and line one by one, which may extend the time to find faults from the original few minutes to several hours. Therefore, an auxiliary device for the maintenance and installation of power equipment for smart grids is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an auxiliary device for the maintenance and installation of power equipment for smart grids in view of the above deficiencies in the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: an auxiliary device for the maintenance and installation of power equipment used in an intelligent power grid, including a chassis. A support device is provided on the inner wall of the chassis, a line protection device is provided on the inner wall of the chassis, and a cleaning device is provided on the inner wall of the chassis; The support device includes a first moving plate, a first fixing plate, a hinge rod, a second fixing plate, a cabinet door, a motor, a positioning plate, a second moving plate, a first reciprocating lead screw, a first guiding plate, a second guiding plate, a first L-shaped plate, a first spring, a second spring, and a second L-shaped plate. The first moving plate is slidably connected to the inner wall of the chassis through a slide rail. The movement of the first moving plate facilitates pulling out electrical components, making it convenient for maintenance personnel to repair the electrical components on the power distribution cabinet. The structural design of the power distribution cabinet is convenient for maintenance, enabling maintenance personnel to quickly find the electrical components with problems. The layout inside the chassis is reasonable, the components in different functional areas are clearly divided, and there are clear markings. Then, maintenance personnel can quickly locate the area where the faulty components may be based on the fault phenomenon and circuit principle. If there are faults in some motor control circuits, maintenance personnel can quickly find corresponding components such as contactors and relays for inspection according to the pre-designed layout diagram. The first fixing plate is fixedly connected to the front of the first moving plate. The hinge rod is hinged inside the first fixing plate. The cabinet door is installed on the inner wall of the chassis. The second fixing plate is fixedly connected to the rear of the cabinet door.

The second moving plate is movably connected to the circumferential surface of the first reciprocating lead screw. The first guiding plate is fixedly connected to the bottom of the second moving plate. The second guiding plate is fixedly connected to the bottom of the second moving plate. The first L-shaped plate is slidably connected to the inner wall of the chassis. The first spring is fixedly connected to the right side of the first L-shaped plate. The second L-shaped plate is slidably connected to the inner wall of the chassis. The second spring is fixedly connected to the rear of the second L-shaped plate. The front of the second spring is fixedly connected to the inner wall of the chassis. The right side of the first spring is fixedly connected to the inner wall of the chassis. The second fixing plate is hinged to the hinge rod. The circumferential surface of the first reciprocating lead screw is rotatably connected to the inner wall of the chassis. The outer wall of the cabinet door contacts the inner wall of the chassis. The inner wall of the positioning plate contacts the circumferential surface of the first reciprocating lead screw. The inner wall of the positioning plate contacts the circumferential surface of the first reciprocating lead screw and the first L-shaped plate moves to the right to support the left and right sides of the power distribution cabinet. Through four-direction support, when screws need to be fixed to the power distribution cabinet during maintenance, it can prevent the power distribution cabinet from vibrating and tilting or collapsing. If the power distribution cabinet tilts or collapses, the internal electrical components will be subjected to strong impacts and vibrations. Sensitive control components such as circuit breakers and contactors may cause deformation of the internal mechanical structure, displacement of contacts, or failure of springs due to collisions. For electronic components such as chips, capacitors, and resistors on circuit boards, vibration is likely to cause solder joints to loosen, components to become desoldered, or internal circuits of chips to be damaged, making these components unable to work properly.

[0007] Preferably, the line protection device includes a first horizontal plate, rollers, a first support plate, a clamping plate, a second reciprocating screw rod, a cam, a vertical plate, a chute plate, a pressing plate, a third spring, and a protection plate. The first horizontal plate is fixedly connected to the rear of the first moving plate. The first support plate is fixedly connected to the inner wall of the chassis. The rollers are in contact with the first support plate. The second reciprocating screw rod is fixedly connected to the right side of the rollers. The clamping plate is movably connected to the circumferential surface of the second reciprocating screw rod. The clamping plate moves to clamp and fix the lines in the power distribution cabinet. The internal space of the power distribution cabinet is limited, and there are usually various lines intersecting or running in parallel. If the lines are not fixed, they are likely to shift under the action of daily maintenance, equipment operation, or other accidental factors. Once the lines shift, they may rub or collide with other lines, electrical components, or the cabinet structure. If the power line and the signal line rub against each other, the insulating outer skin of the signal line may be worn out, resulting in signal interference or short-circuit faults. By clamping and fixing, the lines can be constrained in specific positions, avoiding unnecessary contact between the lines and between the lines and other objects, thereby reducing the probability of wear and faults. The cam is fixedly connected to the right side of the second reciprocating screw rod. The vertical plate is in contact with the cam.

The left side of the vertical plate is in contact with the right side of the chute plate. The circumferential surface of the second reciprocating screw rod is rotatably connected to the inner wall of the first support plate. When the vertical plate moves downward, it drives the pressing plate to move downward, squeezing the lines into the grooves of the protection plate. When the lines are respectively squeezed into different grooves, the distance between the lines is ensured. This physical isolation method can effectively prevent short circuits between the lines due to reasons such as damaged insulation layers. In a high-voltage power distribution cabinet, if there are no good isolation measures for high-voltage lines and low-voltage lines, once the insulation layer ages or is damaged, high voltage may penetrate into the low-voltage circuit, causing serious electrical accidents. The existence of the grooves is like insulating barriers, separating different lines, reducing the risk of short circuits, and enhancing the safety of the entire power distribution cabinet line system.

[0008] Preferably, the cleaning device includes a movable plate three, an L-shaped plate three, a toggle plate, a ventilation shell, a rotating fan, a scraper, a horizontal plate two, a sliding rod, a spring four, a support plate two, a circular plate, and a filter barrel. The movable plate three is fixedly connected to the right side of the vertical plate, the L-shaped plate three is fixedly connected to the front of the movable plate three, the toggle plate is fixedly connected to the front of the L-shaped plate three, the ventilation shell is fixedly connected to the inner wall of the chassis, the rotating fan is rotatably connected to the left side of the ventilation shell, and the scraper is fixedly connected to the rotating shaft of the rotating fan. The scraper is L-shaped and will scrape off dust from the inner wall of the entire ventilation shell, so that the distribution cabinet has a good ventilation effect. At the same time, the dust in the external air is collected through the ventilation shell to prevent dust from entering the distribution cabinet, making it easier to troubleshoot the distribution cabinet during maintenance. When there is no excessive dust accumulation in the distribution cabinet, the maintenance personnel can clearly see the true state of the electrical components during maintenance, and can directly observe whether the contacts of components such as relays and contactors have signs of ablation, whether the connecting screws are loose, etc. If the dust There are many of them, and these problems may be covered by dust, which increases the difficulty of troubleshooting. Moreover, for some components with indicator lights, a clean environment can allow maintenance personnel to accurately judge the status of the indicator lights, so as to better understand the working conditions of the components. The horizontal plate two is fixedly connected to the front of the movable plate three, the sliding rod is fixedly connected to the bottom of the movable plate three, the spring four is fixedly connected to the bottom of the horizontal plate two, the support plate two is fixedly connected to the inner wall of the chassis, the circular plate is fixedly connected to the circumferential surface of the sliding rod, the filter barrel is fixedly connected to the bottom of the support plate two, the scraper contacts the inner wall of the ventilation shell, the bottom of the spring four is fixedly connected to the top of the support plate two, the sliding rod is slidably connected to the inner wall of the support plate two, the sliding rod is slidably connected to the inner wall of the filter barrel, the circumferential surface of the circular plate is slidably connected to the inner wall of the filter barrel, and the sliding rod is driven to move by the movement of the movable plate three, and the movement of the sliding rod drives the circular plate to move, so that the desiccant in each layer of the circular plate is shaken, so that the contact area between the desiccant and the air is increased, and the drying effect is better.

[0009] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The auxiliary equipment for the maintenance and installation of power equipment used in the smart grid cooperates with each other through the first moving plate, the first fixing plate, the hinge rod, the second fixing plate, the cabinet door, the motor, the positioning plate, the second moving plate, the first reciprocating lead screw, the first guide plate, the second guide plate, the first L-shaped plate, the first spring, the second spring, and the second L-shaped plate. The first moving plate moves to pull out the electrical components, facilitating the maintenance personnel to repair the electrical components on the power distribution cabinet. The structure design of the power distribution cabinet is convenient for maintenance, enabling the maintenance personnel to quickly find the electrical components with problems. The layout inside the chassis is reasonable, the components in different functional areas are clearly divided, and there are clear markings. The maintenance personnel can quickly locate the area where the components that may have failed are located according to the fault phenomenon and circuit principle. If there are faults in some motor control circuits, the maintenance personnel can quickly find the corresponding contactors, relays and other components for inspection according to the pre-designed layout diagram. The first L-shaped plate moves to the right to support the left and right sides of the power distribution cabinet. Through four-direction support, when it is necessary to screw the power distribution cabinet during maintenance, the power distribution cabinet is supported to prevent the power distribution cabinet from vibrating and tilting and collapsing. If the power distribution cabinet tilts and collapses, the internal electrical components will be strongly impacted and vibrated. Sensitive control components such as circuit breakers and contactors may cause deformation of the internal mechanical structure, displacement of the contacts or failure of the springs due to collision. For electronic components such as chips, capacitors, and resistors on the circuit board, vibration is likely to cause loose solder joints, component de-soldering or damage to the internal circuits of the chips, making these components unable to work properly.

[0010] 2. The auxiliary equipment for the maintenance and installation of power equipment for the smart grid cooperates with each other among the horizontal plate 1, roller, support plate 1, clamping plate, reciprocating screw rod 2, roller, vertical plate, slide plate, pressure plate, spring 3 and protection plate, and the distribution cabinet line is clamped and fixed by moving the clamping plate. The internal space of the distribution cabinet is limited, and there are usually multiple lines crossing or parallel to each other. If the line is not fixed, it is easy to shift under the influence of daily maintenance, equipment operation or other accidental factors. Once the line shifts, it may rub and collide with other lines, electrical components or cabinet structures. If the power line and the signal line rub against each other, the insulating sheath of the signal line may be worn out, resulting in signal interference or short circuit failure. By clamping and fixing, the line can be constrained to a specific position. Avoid unnecessary contact between lines and between lines and other objects, thereby reducing the probability of wear and failure. The vertical plate moves downward, driving the extrusion plate to move downward, squeezing the lines into the grooves of the protective plate. When the lines are squeezed into different grooves respectively, the distance between the lines is guaranteed. This physical isolation method can effectively prevent short circuits between lines due to insulation damage and other reasons. In a high-voltage distribution cabinet, if there are no good isolation measures for high-voltage and low-voltage lines, once the insulation layer ages or is damaged, high-voltage electricity may flow into the low-voltage circuit and cause serious electrical accidents. The presence of the grooves is like an insulating barrier that separates different lines, reduces the risk of short circuits, and enhances the safety of the entire distribution cabinet line system.

[0011] 3. The auxiliary equipment installed for the maintenance of power equipment for the smart grid cooperates with each other through the movable plate 3, L-shaped plate 3, toggle plate, ventilation shell, rotating fan, scraper, horizontal plate 2, slide rod, spring 4, support plate 2, round plate and filter barrel. The scraper is L-shaped and will scrape the dust in the inner wall of the entire ventilation shell, so that the ventilation effect of the distribution cabinet is good. At the same time, the dust in the external air is collected through the ventilation shell to prevent dust from entering the distribution cabinet, making it easier to troubleshoot the distribution cabinet during maintenance. When there is no excessive dust accumulation in the distribution cabinet, the maintenance personnel can clearly see the electrical appliances during maintenance. The real status of the components can directly observe whether the contacts of components such as relays and contactors have signs of ablation, whether the connecting screws are loose, etc. If there is a lot of dust, these problems may be covered by the dust, increasing the difficulty of troubleshooting. Moreover, for some components with indicator lights, a clean environment can allow maintenance personnel to accurately judge the status of the indicator lights, so as to better understand the working conditions of the components. The movement of the moving plate drives the movement of the sliding rod, and the movement of the sliding rod drives the movement of the circular plate, so that the desiccant on each layer of the circular plate is shaken, so that the contact area between the desiccant and the air is increased, and the drying effect is better.

The first moving plate 201 is slidably connected to the inner wall of the chassis 1 through a slide rail. When the device is started and the power distribution cabinet needs to be maintained, the maintenance personnel open the cabinet door 205. The movement of the cabinet door 205 drives the movement of the second fixing plate 204. The movement of the second fixing plate 204 drives the movement of the hinge rod 203. The movement of the hinge rod 203 drives the movement of the first fixing plate 202. The movement of the first fixing plate 202 drives the movement of the first moving plate 201. The movement of the first moving plate 201 facilitates pulling out the electrical components for the maintenance personnel to repair the electrical components on the power distribution cabinet. The structural design of the power distribution cabinet is convenient for maintenance, enabling the maintenance personnel to quickly find the faulty electrical components. The layout inside the chassis 1 is reasonable, the components in different functional areas are clearly divided, and there are clear markings. The maintenance personnel can then, according to the fault phenomenon and circuit principle, quickly locate the area where the faulty components may be. If there are faults in the control circuits of some motors 206, the maintenance personnel can, according to the pre-designed layout diagram, quickly find the corresponding contactors, relays and other components for inspection. The first fixing plate 202 is fixedly connected to the front of the first moving plate 201. The hinge rod 203 is hinged inside the first fixing plate 202. The cabinet door 205 is installed on the inner wall of the chassis 1. The second fixing plate 204 is fixedly connected to the rear of the cabinet door 205.

The L-shaped plate 213 is slidably connected to the inner wall of the chassis 1. The first spring 214 is fixedly connected to the right side of the L-shaped plate 213. The L-shaped plate 216 is slidably connected to the inner wall of the chassis 1. The second spring 215 is fixedly connected to the rear of the L-shaped plate 216. The front of the second spring 215 is fixedly connected to the inner wall of the chassis 1. The right side of the first spring 214 is fixedly connected to the inner wall of the chassis 1. The second fixing plate 204 is hinged to the hinge rod 203. The circumferential surface of the first reciprocating lead screw 209 is rotatably connected to the inner wall of the chassis 1. The outer wall of the cabinet door 205 is in contact with the inner wall of the chassis 1. The inner wall of the positioning plate 207 and the circumferential surface of the first reciprocating lead screw 209. The first reciprocating lead screw 209 is rotated by the motor 206.The movement of the second moving plate 208 is driven by the crossed spiral groove on the reciprocating lead screw 209. The movement of the second moving plate 208 drives the movement of the first guiding plate 210. At the same time, the movement of the second moving plate 208 drives the movement of the second guiding plate 211. When the first guiding plate 210 moves, it will contact the second L-shaped plate 216, and the second L-shaped plate 216 moves backward to support the rear part of the power distribution cabinet. The movement of the second moving plate 208 will contact the first L-shaped plate 213, and the first L-shaped plate 213 moves to the right upon contact to support the left and right sides of the power distribution cabinet. Through four-direction support, when screws need to be fixed to the power distribution cabinet during maintenance, the power distribution cabinet can be supported to prevent it from tilting and collapsing due to vibration. If the power distribution cabinet tilts and collapses, the internal electrical components will be subjected to strong impacts and vibrations. Sensitive control components such as circuit breakers and contactors may cause deformation of the internal mechanical structure, displacement of the contacts, or failure of the springs due to collisions. For electronic components, such as chips, capacitors, and resistors on the circuit board, vibration easily causes loose solder joints, component desoldering, or damage to the internal circuits of the chips, rendering these components unable to work properly.,

[0016] The line protection device 3 includes a first horizontal plate 301, rollers 302, a first support plate 303, a clamping plate 304, a second reciprocating lead screw 305, a cam 306, a vertical plate 307, a chute plate 308, a pressing plate 309, a third spring 310, and a protection plate 311. The first horizontal plate 301 is fixedly connected to the rear of the first moving plate 201, the first support plate 303 is fixedly connected to the inner wall of the chassis 1, the rollers 302 are in contact with the first support plate 303, the second reciprocating lead screw 305 is fixedly connected to the right side of the rollers 302, the clamping plate 304 is movably connected to the circumferential surface of the second reciprocating lead screw 305. The movement of the first moving plate 201 drives the movement of the first horizontal plate 301, the movement of the first horizontal plate 301 drives the rotation of the rollers 302, the rotation of the rollers 302 drives the rotation of the second reciprocating lead screw 305, and the clamping plate 304 is driven to move by the crossed spiral grooves on the second reciprocating lead screw 305. The clamping plate 304 moves to clamp and fix the power distribution cabinet lines. The internal space of the power distribution cabinet is limited, and there are usually multiple lines intersecting or running in parallel. If the lines are not fixed, they are likely to shift under the action of daily maintenance, equipment operation, or other accidental factors. Once the lines shift, they may rub or collide with other lines, electrical components, or the cabinet structure. If the power line and the signal line rub against each other, it may wear through the insulating outer skin of the signal line, resulting in signal interference or short circuit faults. By clamping and fixing, the lines can be constrained in specific positions, avoiding unnecessary contact between the lines and between the lines and other objects, thereby reducing the probability of wear and faults. The cam 306 is fixedly connected to the right side of the second reciprocating lead screw 305, the vertical plate 307 is in contact with the cam 306, the chute plate 308 is fixedly connected to the inner wall of the chassis 1, the pressing plate 309 is slidably connected to the inner wall of the chute plate 308, the third spring 310 is fixedly connected to the bottom of the vertical plate 307, the protection plate 311 is fixedly connected to the inner wall of the chassis 1, the right side of the pressing plate 309 is fixedly connected to the left side of the vertical plate 307, the rear part of the pressing plate 309 is in contact with the front part of the protection plate 311, the left side of the vertical plate 307 is in contact with the right side of the chute plate 308, and the circumferential surface of the second reciprocating lead screw 305 is rotatably connected to the inner wall of the first support plate 303. The rotation of the second reciprocating lead screw 305 drives the rotation of the cam 306, the rotation of the cam 306 drives the vertical plate 307 to move downward, and the downward movement of the vertical plate 307 drives the pressing plate 309 to move downward, squeezing the lines into the grooves of the protection plate 311. When the lines are respectively squeezed into different grooves, the distance between the lines is ensured. This physical isolation method can effectively prevent short circuits between the lines due to reasons such as insulation layer breakage. In a high-voltage power distribution cabinet, if there are no good isolation measures for high-voltage lines and low-voltage lines, once the insulation layer ages or is damaged, high voltage may penetrate into the low-voltage circuit, causing serious electrical accidents. The existence of the grooves is like a series of insulating barriers, separating different lines, reducing the risk of short circuits, and enhancing the safety of the entire power distribution cabinet line system.

[0017] Working principle: When the device starts up and the power distribution cabinet needs to be repaired, the maintenance personnel open the cabinet door 205. The movement of the cabinet door 205 drives the movement of the second fixing plate 204. The movement of the second fixing plate 204 drives the movement of the hinge rod 203. The movement of the hinge rod 203 drives the movement of the first fixing plate 202. The movement of the first fixing plate 202 drives the movement of the first moving plate 201. The movement of the first moving plate 201 facilitates pulling out the electrical components, making it convenient for the maintenance personnel to repair the electrical components on the power distribution cabinet. The structural design of the power distribution cabinet is convenient for maintenance, enabling the maintenance personnel to quickly locate the electrical components with problems. The layout inside the chassis 1 is reasonable, the components in different functional areas are clearly divided, and there are clear markings. The maintenance personnel can then quickly locate the area where the faulty components may be based on the fault phenomenon and circuit principle. If there are faults in the control circuits of some motors 206, the maintenance personnel can quickly find the corresponding contactors, relays and other components for inspection according to the pre-designed layout diagram. The rotation of the reciprocating lead screw 209 is driven by the motor 206. The movement of the second moving plate 208 is driven by the cross-shaped spiral groove on the reciprocating lead screw 209. The movement of the second moving plate 208 drives the movement of the first guide plate 210. At the same time, the movement of the second moving plate 208 drives the movement of the second guide plate 211. When the first guide plate 210 moves, it will contact the second L-shaped plate 216, and the second L-shaped plate 216 moves backward to support the rear part of the power distribution cabinet. When the second moving plate 208 moves, it will contact the first L-shaped plate 213, and the first L-shaped plate 213 moves to the right to support the left and right sides of the power distribution cabinet. Through the four-direction support, when the power distribution cabinet needs to be fixed with screws during maintenance, it can be supported to prevent the power distribution cabinet from tilting and collapsing due to vibration. If the power distribution cabinet tilts and collapses, the internal electrical components will be subjected to strong impacts and vibrations. Sensitive control components such as circuit breakers and contactors may cause deformation of the internal mechanical structure, displacement of the contacts or failure of the springs due to collisions. For electronic components such as chips, capacitors, and resistors on the circuit board, vibration is likely to cause loose solder joints, component de-soldering or damage to the internal circuits of the chips, making these components unable to work properly.

[0018] The movement of the first moving plate 201 drives the movement of the first cross plate 301. The movement of the first cross plate 301 drives the rotation of the roller 302. The rotation of the roller 302 drives the rotation of the second reciprocating lead screw 305. The cross-shaped spiral groove on the second reciprocating lead screw 305 drives the movement of the clamping plate 304. The movement of the clamping plate 304 clamps and fixes the power distribution cabinet lines. The internal space of the power distribution cabinet is limited, and there are usually multiple lines intersecting or running in parallel. If the lines are not fixed, they are likely to shift under the action of daily maintenance, equipment operation or other accidental factors. Once the lines shift, they may rub or collide with other lines, electrical components or the cabinet structure. If the power line and the signal line rub against each other, the insulating outer skin of the signal line may be worn out, resulting in signal interference or short circuit faults. Through clamping and fixing, the lines can be restricted to specific positions, avoiding unnecessary contact between the lines and between the lines and other objects, thereby reducing the occurrence probability of wear and faults. The rotation of the second reciprocating lead screw 305 drives the rotation of the cam 306. The rotation of the cam 306 drives the downward movement of the vertical plate 307. The downward movement of the vertical plate 307 drives the downward movement of the pressing plate 309, pressing the lines into the grooves of the protection plate 311. When the lines are respectively pressed into different grooves, the distance between the lines is ensured. This physical isolation method can effectively prevent short circuits between the lines due to reasons such as damaged insulation layers. In a high-voltage power distribution cabinet, if there are no good isolation measures for high-voltage lines and low-voltage lines, once the insulation layer ages or is damaged, high-voltage electricity may rush into the low-voltage circuit, triggering serious electrical accidents. The existence of the grooves is like insulating barriers, separating different lines, reducing the risk of short circuits, and enhancing the safety of the entire power distribution cabinet line system.
