Description

Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, and more specifically, it relates to a high-voltage switchgear that is easy to maintain. Background Technology

[0002] High-voltage switchgear, also known as high-voltage switch cabinet, refers to a complete set of power distribution equipment used in power systems for power generation, transmission, distribution, energy conversion, and consumption. It connects and disconnects circuits, and provides protection, control, and measurement functions. High-voltage switchgear plays a crucial role in the power grid, connecting and disconnecting power lines. It allows power engineers to put parts of the circuit into or out of operation as needed. Through isolating switches, it forms a visible and safe disconnect point, ensuring the safety of equipment and personnel. High-voltage switchgear can quickly disconnect faulty circuits, preventing accidents from escalating and protecting important downstream equipment from damage. Through internal voltage and current transformers, it converts high voltage and high current into standard low voltage and low current signals for use by instruments and monitoring systems to monitor power parameters in real time. However, existing high-voltage switchgear has certain problems and defects that can affect power transmission.

[0003] Firstly, high-voltage switchgear will be damaged and require maintenance during use. In the current technology, high-voltage switchgear is designed as a whole with a low degree of modularity, which makes maintenance difficult during use, resulting in low equipment efficiency and poor equipment usability.

[0004] Secondly, during equipment maintenance, the equipment needs to be disassembled, which makes the process cumbersome and the disassembly efficiency low, resulting in low equipment working efficiency.

[0005] Furthermore, the disassembly process of the equipment requires manual operation, resulting in a low degree of automation and thus poor practicality. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a high-voltage switchgear that is easy to maintain, so as to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a high-voltage switchgear that is easy to maintain, comprising a base, an assembly device on the base, the assembly device comprising a module plate, the top end of the module plate being connected to the bottom end of the base, a hinge seat on the module plate, a rotating shaft rotatably connected to the hinge seat, a crank rod on the rotating shaft, a rear side plate at one end of the crank rod, a positioning seat on the rear side plate, a folding plate rotatably connected to the positioning seat, a buckle on the folding plate, a side plate at one end of the buckle, a module device on the base, the module device comprising a sliding frame, a round tube on the side plate, the sliding frame passing through the round tube and slidably connected to the side plate, a spring fitted on the sliding frame, one end of the spring being connected to one end of the round tube, and a drive assembly on the base.

[0008] This utility model is further configured as follows: a column is provided on the base, a support rod is slidably connected to the column, a top plate is slidably connected to the top of the support rod, a door is fitted onto the support rod, and a knob is provided on both the column and the top plate. During equipment maintenance, rotating the shaft causes the connected crank rod to rotate along the hinge, thereby causing the rear side plate to change from a perpendicular state to a parallel state. After unfolding, the side plate connected to the rear side plate rotates accordingly. During this process, rotating the folding plate causes it to rotate on the positioning seat. The rotation causes the latches to rotate as well, which in turn causes the side panels to unfold. By laying them flat, the ease of maintenance of the equipment is improved, thus enhancing its practicality. During this process, when disassembling the side panels, the sliding bracket can be pulled to slide along the circular tube. After sliding, the sliding bracket and the latches are separated, changing the side panels from a latched state to a disassembled state, allowing for independent disassembly of the side panels. When disassembling the rear side panels independently, modular disassembly is achieved by removing the module plate, thereby improving the modularity of the equipment and increasing its working efficiency.

[0009] The present invention is further configured such that: an opening is provided through the rear side plate, and a ventilation plate is fitted onto the opening; during the use of the equipment, the ventilation plate is installed to ventilate the inside of the equipment, thereby improving the functionality of the equipment and thus improving its practicality.

[0010] This utility model is further configured such that: the driving component includes a guide rail, the top end of the guide rail is connected to the bottom end of the module plate, an adjusting block is slidably connected to the guide rail, an electric push rod is fitted on the adjusting block, the base end of the electric push rod is connected to one end of the module plate, a positioning rack is provided on the adjusting block, a positioning gear is engaged with the positioning rack, one end of the positioning gear is connected to one end of the rotating shaft. During the automatic disassembly of the equipment, the electric push rod is activated, causing its output end to slide. This sliding motion drives the adjusting block connected to it to slide along the guide rail, thereby driving the positioning rack to slide. Through the meshing relationship between the positioning rack and the positioning gear, the rotating shaft is driven to rotate, thereby driving the crank to rotate, thus improving the automation level of the equipment and enhancing its practicality.

[0011] This utility model is further configured such that: a fixed seat is provided on the folding plate, a fixed rod is provided on the fixed seat, and an I-beam is hinged to the fixed rod. An electric push rod is provided at one end of the I-beam, and the base end of the electric push rod is connected to one end of the rear side plate. When the side plate is rotated, the electric push rod is activated, causing its output end to slide. During the sliding process, the connected I-beam slides accordingly, and the fixed rod is pulled by the sliding to drive the folding plate, thereby driving the side plate to rotate and decompose. This improves the automation level of the equipment and thus improves the practicality of the equipment.

[0012] This utility model is further configured such that: a crossbeam is fitted onto the support rod, a positioning clip is mounted on the crossbeam, an adjusting rack is slidably connected to the positioning clip, and an adjusting gear is engaged with the adjusting rack; a motor is mounted on the crossbeam. When the equipment is being stored, the motor is started to rotate, causing the adjusting gear connected to it to rotate as well. The adjusting gear drives the adjusting rack, which is engaged with it, to slide from both sides, thus storing or unfolding the equipment. During storage, the sliding column and top plate extend and retract from the support rod, and the tension is adjusted by rotating a knob threaded to them. This improves the automation level of the equipment and enhances its practicality.

[0013] The present invention is further configured such that: a connecting seat is provided on the adjusting rack, and a fixed rail is rotatably connected to the connecting seat; when disassembling the equipment, the fixed rail can be rotated to allow the wiring or equipment to rotate on the connecting seat for storage, thereby improving the convenience of the equipment and thus improving its practicality.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention has the following beneficial effects: 1. During equipment maintenance, rotate the shaft to drive the connected crank to rotate along the hinge seat. This rotation causes the rear side plate to change from a perpendicular state to a parallel state. After unfolding, the side plate connected to the rear side plate rotates accordingly. During this process, rotate the folding plate to rotate on the positioning seat. This rotation causes the buckle to rotate, thereby unfolding the side plate. By laying it flat, the ease of equipment maintenance is improved, thus enhancing the practicality of the equipment. 2. When disassembling side panels, the sliding bracket can be pulled to slide along the round tube. After sliding, the sliding bracket and the buckle can be separated, changing the side panel from the clamped state to the disassembled state. This allows the side panel to be disassembled independently. When disassembling the rear side panel independently, the modular disassembly is completed by disassembling the module plate, thereby improving the modularity of the equipment and thus improving the working efficiency of the equipment. 3. During the automatic disassembly of the equipment, start the electric push rod one, so that its output end slides. The sliding causes the adjustment block connected to it to slide along the guide rail, which in turn drives the positioning rack to slide. Through the meshing relationship between the positioning rack and the positioning gear, the rotating shaft is driven to rotate, which in turn drives the crank to rotate, thereby improving the automation level of the equipment and thus improving its practicality.

[0021] In the embodiments of this application: a column 14 is provided on the base 1, a support rod 15 is slidably connected to the column 14, a top plate 16 is slidably connected to the top of the support rod 15, a door 17 is fitted onto the support rod 15, and a knob 18 is provided on both the column 14 and the top plate 16. During equipment maintenance, rotating the shaft 4 causes the connected crank rod 5 to rotate along the hinge 3, thereby causing the rear side plate 6 to change from a perpendicular state to a parallel state. After unfolding, the lateral side plate 6 connected to the rear side plate 6... The plate 10 rotates accordingly. During this process, the folding plate 8 rotates on the positioning seat 7. The rotation drives the buckle 9 to rotate as well, thereby causing the side plate 10 to unfold. During this process, when disassembling the side plate 10, the sliding frame 11 can be pulled to slide along the round tube 12. After sliding, the sliding frame 11 and the buckle 9 are separated, changing the side plate 10 from the snap-fit ​​state to the disassembly state. The side plate 10 can be disassembled independently. When disassembling the rear side plate 6 independently, the modular disassembly is completed by disassembling the module plate 2.

[0022] More specifically: an opening 19 is provided through the rear side plate 6, and a ventilation plate 20 is fitted onto the opening 19. During the use of the equipment, the ventilation plate 20 is installed to ventilate the inside of the equipment.

[0023] More specifically: the drive assembly includes a guide rail 21, the top end of which is connected to the bottom end of the module plate 2. An adjusting block 22 is slidably connected to the guide rail 21. An electric push rod 23 is fitted on the adjusting block 22. The base end of the electric push rod 23 is connected to one end of the module plate 2. A positioning rack 24 is provided on the adjusting block 22. A positioning gear 25 is meshed with the positioning rack 24. One end of the positioning gear 25 is connected to one end of the rotating shaft 4. During the automatic disassembly of the equipment, the electric push rod 23 is activated, causing its output end to slide. This sliding motion drives the adjusting block 22 connected to it to slide along the guide rail 21, thereby driving the positioning rack 24 to slide. Through the meshing relationship between the positioning rack 24 and the positioning gear 25, the rotating shaft 4 is driven to rotate, thereby driving the crank 5 to rotate.

[0024] More specifically: a fixed seat 26 is provided on the folding plate 8, a fixed rod 27 is provided on the fixed seat 26, an I-beam 28 is hinged on the fixed rod 27, and an electric push rod 29 is provided at one end of the I-beam 28. The base end of the electric push rod 29 is connected to one end of the rear side plate 6. When the side plate 10 is rotated, the electric push rod 29 is activated, causing its output end to slide. During the sliding process, the I-beam 28 connected to it slides accordingly, and the fixed rod 27 is pulled by the sliding.

[0025] More specifically: A crossbeam 30 is fitted onto the support rod 15, a positioning clip 31 is fitted onto the crossbeam 30, an adjusting rack 32 is slidably connected to the positioning clip 31, and an adjusting gear 33 is engaged with the adjusting rack 32. A motor 34 is fitted onto the crossbeam 30. When the equipment is being stored, the motor 34 is started to rotate, causing the adjusting gear 33 connected to it to rotate as well. The adjusting gear 33 drives the adjusting rack 32 to slide from both sides, thus storing or unfolding the equipment. When storing, the sliding column 14 and the top plate 16 are used to extend and retract from the support rod 15, and the tension is adjusted by rotating the screw-connected knob 18.

[0026] More specifically: the adjusting rack 32 is provided with a connecting seat 35, and a fixed rail 36 is rotatably connected to the connecting seat 35. When disassembling the equipment, the fixed rail 36 can be rotated to allow the lines or equipment to rotate on the connecting seat 35 for storage.

[0027] In summary, during equipment maintenance, rotating the shaft 4 causes the connected crank 5 to rotate along the hinge 3. This rotation causes the rear side plate 6 to change from a perpendicular state to a parallel state with the base 1. After unfolding, the side plate 10 connected to the rear side plate 6 rotates accordingly. During this process, rotating the folding plate 8 causes it to rotate on the positioning seat 7. This rotation causes the buckle 9 to rotate, thereby unfolding the side plate 10. When disassembling the side plate 10, the sliding frame 11 can be pulled to slide along the round tube 12. After sliding, the sliding frame 11 and the buckle 9 are separated, changing the side plate 10 from a locked state to a disassembled state. This allows for independent disassembly of the side plate 10. When disassembling the rear side plate 6 independently, modular disassembly is achieved by disassembling the module plate 2. During the automatic disassembly of the equipment, the electric push rod 23 is activated, causing its output end to slide. The sliding action causes the adjusting block 22 connected to it to slide along the guide rail 21, thereby causing the positioning rack 24 to slide. Through the meshing relationship between the positioning rack 24 and the positioning gear 25, the rotating shaft 4 is driven to rotate, thereby causing the crank 5 to rotate. When the side plate 10 is rotated, the electric push rod 29 is activated, causing its output end to slide. During the sliding process, the I-beam frame 28 connected to it is driven to slide as well. The sliding action causes the fixed rod 27 to pull the folding plate 8. When the equipment is being stored, the motor 34 is activated, causing the adjusting gear 33 connected to it to rotate. The adjusting gear 33 drives the adjusting rack 32, which is meshed with it, to slide from both sides. The sliding action is used to store or unfold the equipment. When storing the equipment, the sliding column 14 and the top plate 16 are used to extend and retract from the support rod 15. The tension is adjusted by rotating the knob 18 connected to it.
