Description

Technical Field

[0001] This invention relates to the field of hybrid governance device technology, specifically a hybrid power quality comprehensive governance device for power distribution networks. Background Technology

[0002] The power quality management equipment for distribution networks is a core supporting device in the operation and maintenance system of distribution networks. It is mainly integrated and installed inside the comprehensive management cabinet. It is used to monitor, adjust and optimize various power quality problems in the operation of distribution networks, and ensure the stability and standardization of power supply in distribution networks. During the operation of this type of equipment, a large number of connection lines need to be laid. The orderly layout and safe operation of the lines directly affect the overall working status of the equipment.

[0003] Currently, the wiring inside the existing integrated management cabinets is mostly scattered. During long-term operation, maintenance, and repair, the wiring is prone to tangling, misalignment, and loosening. The messy wiring layout not only increases the difficulty of maintenance, inspection, and replacement for staff, but also easily leads to wear and tear on the wiring, posing certain operational safety hazards.

[0004] To meet the requirements of integrated equipment installation, the internal space of the comprehensive management cabinet is relatively enclosed. After the cables are neatly stored, they will be concentrated in a fixed area. During long-term operation, the cable harnesses continuously generate working heat. It is impossible to specifically ventilate and dissipate heat in the concentrated cable harness area. The poor air circulation inside the cabinet makes it easy for the cable harnesses to accumulate heat. The cable harnesses are in a high-temperature environment for a long time, which will accelerate the aging of the cable insulation layer and aggravate the line loss. This will not only affect the quality of power transmission, but also reduce the service life of the lines and equipment. In severe cases, it will cause line faults and affect the stable and continuous operation of the power quality comprehensive management equipment of the distribution network. Summary of the Invention

[0005] The purpose of this invention is to provide a hybrid power quality management device for power distribution networks. This addresses the problem that existing integrated management cabinets often have dispersed wiring, which easily leads to tangling, misalignment, and loosening of wires during long-term operation and maintenance. This chaotic wiring arrangement not only increases the difficulty of maintenance, inspection, and replacement for staff but also easily causes wire wear and tear, posing certain operational safety hazards. Furthermore, when wires are neatly stored, they tend to accumulate in a fixed area. During long-term operation, the wire bundles continuously generate heat, and there is no targeted ventilation or heat dissipation for this concentrated area. Poor air circulation within the cabinet easily leads to heat accumulation in the wire bundles, and prolonged exposure to high temperatures accelerates the aging of the wire insulation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hybrid power distribution network power quality comprehensive management device, comprising a comprehensive management cabinet, a cabinet door movably connected to the left side of the comprehensive management cabinet, comprehensive management equipment installed inside the comprehensive management cabinet, mounting plates fixedly connected to the front and rear sides of the top and bottom of the comprehensive management equipment, the two sides of the mounting plates fixedly connected to the two sides of the inner wall of the comprehensive management cabinet, an air inlet pipe connected to the top of the comprehensive management cabinet, a cable management seat fixedly connected to the front side of the bottom of the inner wall of the comprehensive management cabinet, cable management plates movably connected to the two sides of the top of the cable management seat, a cable groove opened on the side of the cable management seat and the cable management plate that are close to each other, an overheat protection mechanism fixedly installed inside the air inlet pipe, and a cable management mechanism fixedly connected to the top of the cable management plate.

[0007] Preferably, the overheat protection mechanism includes an upper mounting base, which is fixedly connected to the inside of the air inlet duct. A lower mounting base is fixedly connected to the bottom of the integrated management cabinet. Fans are movably connected inside both the upper and lower mounting bases. By setting the fans, corresponding heat dissipation and air supply points can be formed inside the cabinet, breaking the limitation of the limited heat dissipation range of a single fan. This structure is adapted to the cabinet layout of the integrated management cabinet and can specifically cover the cable management area inside the cabinet, providing a stable airflow output foundation for subsequent cable harness heat dissipation. The structural layout fits the equipment installation requirements, has strong adaptability, and can stably ventilate and dissipate heat from the neatly arranged cable harnesses inside the cabinet.

[0008] Preferably, a driven helical gear one is fixedly connected to the top of the fan, and a driven helical gear two meshes with the top of the driven helical gear one. A drive shaft is fixedly connected to the rear side of the driven helical gear two, and the rear side of the drive shaft extends through to the rear side of the integrated management cabinet. Through the setting of the drive shaft, external driving power can be stably transmitted to the fan, realizing the controllable rotation operation of the fan. This transmission structure has a compact layout. Relying on the design of the drive shaft extending through the cabinet, the power source can be set on the outside of the cabinet, avoiding the power structure occupying the space of equipment and cable management inside the cabinet. At the same time, the helical gear transmission runs smoothly, which can ensure the continuous and stable operation of the fan and ensure the continuity of heat dissipation.

[0009] Preferably, a first active helical gear is fixedly connected to the rear side of the drive shaft, a second active helical gear meshes with the inner side of the first active helical gear, and a drive shaft is fixedly connected to the inner side of the second active helical gear. A motor is fixedly connected to the rear side of the integrated treatment cabinet. Transmission gears are fixedly connected to the output end of the motor and the surface of the drive shaft. A toothed belt is fitted onto the surface of the transmission gears. Through the motor, the fan can be precisely driven. This linkage transmission structure has low power transmission loss, high operational stability, and can achieve synchronous start / stop and uniform speed operation of the two fans. Simultaneously, the external installation of the motor reduces heat accumulation inside the cabinet, further improving the overall reliability of the equipment's heat dissipation operation.

[0010] Preferably, the cable management mechanism includes a socket, which is fixedly connected to the left side of the top of the cable management board. A slot is provided on the right side of the socket, and a pin is provided inside the slot. An installation block is fitted on the right side of the pin, and the bottom of the installation block is fixedly connected to the right side of the top of the cable management board. Through the setting of the socket and slot, the cable management board and the cable management base can be detachably and fixedly connected. This structure is simple and neat, adaptable to the opening and closing requirements of the cable management board, and can stably lock the cable management board after cable management is completed, preventing the cable management board from loosening and shifting, which would cause the cable bundle to scatter and become messy. It can realize the quick fixing and unlocking of the internal wiring of the cabinet, and is suitable for the daily use scenarios of equipment wiring layout, maintenance, and replacement, with good practicality.

[0011] Preferably, a movable plate is fixedly connected to the right side of the pin. A round rod is movably connected to both the front and rear sides of the movable plate. The round rod is fixedly connected to the front and rear sides of the mounting block. A spring is sleeved on the surface of the round rod. The left side of the spring is fixedly connected to the right side of the movable plate, and the right side of the spring is fixedly connected to the right side of the inner wall of the mounting block. The spring design prevents the movable plate from sliding, shifting, or jamming. The elastic structure of the spring eliminates the need for manual reset, simplifying the opening and closing operation of the cable management board, improving the convenience of cable management, and ensuring a durable structure with a low failure rate.

[0012] Preferably, a movable plate is fixedly connected to the right side of the pin. A round rod is movably connected to both the front and rear sides of the movable plate. The round rod is fixedly connected to the front and rear sides of the mounting block. A spring is sleeved on the surface of the round rod. The left side of the spring is fixedly connected to the right side of the movable plate, and the right side of the spring is fixedly connected to the right side of the inner wall of the mounting block. The spring design prevents the movable plate from sliding, shifting, or jamming. The elastic structure of the spring eliminates the need for manual reset, simplifying the opening and closing operation of the cable management board, improving the convenience of cable management, and ensuring a durable structure with a low failure rate.

[0013] Preferably, the bottom of the control gear is provided with a fitting groove, the bottom of the fitting groove is provided with a fitting block, and the top of the fitting block is fixedly connected to a lifting rod. The top of the lifting rod extends through to the top of the mounting block, and the surface of the lifting rod is in active contact with the inside of the control gear and the movable sleeve. Through the setting of the fitting groove and the fitting block, the fitting and disengaging states of the fitting block and the fitting groove can be flexibly controlled. Only in the fitted and locked state can the lifting rod drive the control gear to rotate. When unlocked, the gear remains fixed, which can prevent the cable management mechanism from being accidentally unlocked by external force, improve the stability of the cable management board, and effectively prevent the cables from becoming loose and scattered during daily equipment operation.

[0014] Preferably, a knob is fixedly connected to the top of the lifting rod. The knob is located on the top of the mounting block. A through groove is provided on the right side of the mounting block. The through groove is located on the right side of the gear plate. The knob allows the operator to manually lift and rotate the gear plate without the need for auxiliary tools, enabling the unlocking and resetting of the cable management mechanism. The through groove provides ample space for the movement of the gear plate, preventing the mounting block from obstructing or limiting the displacement of the gear plate, ensuring smooth operation of the gear and rack transmission structure, further simplifying the operation process of cable management and improving work efficiency.

[0015] Preferably, a stabilizing plate is fitted onto the surface of the motor output end. The front side of the stabilizing plate is fixedly connected to the rear side of the integrated management cabinet. By setting the stabilizing plate, the vibration offset generated during motor operation can be reduced, and the meshing misalignment and wear problems of transmission gears, tooth belts and helical tooth structures caused by vibration can be reduced. This effectively improves the operational stability of the motor transmission system, extends the service life of transmission components, reduces the frequency of equipment failures, and ensures the long-term stable operation of the heat dissipation mechanism.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through structures such as cable management bases and cable management boards, can conveniently arrange, organize, and fix various types of cables inside the cabinet, uniformly collecting and binding scattered and messy cables, avoiding cable tangling and overlapping. The overall structure is simple to operate, and cable organization can be completed without complicated procedures. It can keep the cable arrangement inside the integrated management cabinet neat and orderly, making it convenient for staff to carry out cable inspection, maintenance, and replacement work, reducing the difficulty of equipment operation and maintenance, and ensuring the orderly and standardized operation of power distribution network equipment lines.

[0017] 2. This invention, through its upper and lower dual-fan heat dissipation structure design, can provide directional ventilation and heat dissipation for neatly arranged wire harness areas. Neatly arranged wire harnesses are prone to heat accumulation. The coordinated operation of the dual fans creates a stable air circulation within the cabinet, accelerating airflow around the wire harness and continuously removing the heat generated during operation. The transmission structure operates smoothly, ensuring the fans operate at a constant speed for extended periods, continuously improving the heat dissipation conditions in the enclosed space of the cabinet. This prevents long-term high-temperature accumulation in the wire harness, which can lead to insulation aging and increased line losses, stabilizing the operating temperature within the cabinet and enhancing the safety and stability of the power distribution network equipment lines.

A lower mounting base 92 is fixedly connected to the bottom of the integrated treatment cabinet 1. Fans 93 are movably connected to the inside of both the upper mounting base 91 and the lower mounting base 92.

[0023] Furthermore, by setting up fan 93, corresponding heat dissipation and air supply points can be formed inside the cabinet, breaking the limitation of the limited heat dissipation range of a single fan 93. This structure is adapted to the cabinet layout of the integrated management cabinet 1, and can specifically cover the cable management area inside the cabinet, providing a stable airflow output foundation for subsequent cable harness heat dissipation. The structural layout fits the equipment installation requirements, has strong adaptability, and can stably ventilate and dissipate heat on the neat cable harness inside the cabinet.

[0024] Please see Figure 1-8 The top of the fan 93 is fixedly connected to a driven helical gear 94, the top of the driven helical gear 94 is engaged with a driven helical gear 95, and the rear side of the driven helical gear 95 is fixedly connected to a drive shaft 96, the rear side of the drive shaft 96 extends through to the rear side of the integrated management cabinet 1.

[0025] Furthermore, by setting the drive shaft 96, external driving power can be stably transmitted to the fan 93, enabling the fan 93 to rotate controllably. This transmission structure has a compact layout. Relying on the design of the drive shaft 96 penetrating through the cabinet, the power source can be placed on the outside of the cabinet, avoiding the power structure from occupying the space of the equipment and cable management inside the cabinet. At the same time, the helical gear transmission runs smoothly, ensuring the continuous and stable operation of the fan 93 and guaranteeing the continuity of heat dissipation.

[0026] Please see Figure 1-8 A drive helical gear 97 is fixedly connected to the rear side of the drive shaft 96. A drive helical gear 98 meshes with the inner side of the drive helical gear 97. A drive shaft 99 is fixedly connected to the inner side of the drive helical gear 98. A motor 910 is fixedly connected to the rear side of the integrated management cabinet 1. A transmission gear 911 is fixedly connected to the output end of the motor 910 and the surface of the drive shaft 99. A toothed belt 912 is sleeved on the surface of the transmission gear 911.

[0027] Furthermore, the motor 910 precisely drives the fan 93. This linkage transmission structure has low power transmission loss and high operational stability, enabling synchronous start-stop and uniform speed operation of both fans 93. Simultaneously, the external mounting of the motor 910 reduces heat accumulation inside the cabinet, further improving the overall reliability of the equipment's heat dissipation operation.

[0028] Please see Figure 1-8The cable management mechanism 10 includes a socket 101, which is fixedly connected to the left side of the top of the cable management plate 7. A slot 102 is provided on the right side of the socket 101. A pin 103 is provided inside the slot 102. An installation block 104 is fitted on the right side of the surface of the pin 103. The bottom of the installation block 104 is fixedly connected to the right side of the top of the cable management plate 7.

[0029] Furthermore, the cable management board 7 and the cable management base 6 can be detachably and fixedly connected through the socket 101 and slot 102. This structure is simple and neat, adaptable to the opening and closing requirements of the cable management board 7, and can stably lock the cable management board 7 after cable management is completed, preventing the cable management board 7 from loosening and shifting, which would cause the cable bundle to scatter and become messy. It can realize the quick fixing and unlocking of the internal wiring of the cabinet, and is suitable for the daily use scenarios of equipment wiring layout, maintenance and replacement, with good practicality.

[0030] Please see Figure 1-8 A movable plate 105 is fixedly connected to the right side of the pin 103. A round rod 106 is movably connected to both the front and rear sides inside the movable plate 105. The round rod 106 is fixedly connected to the front and rear sides inside the mounting block 104. A spring 107 is sleeved on the surface of the round rod 106. The left side of the spring 107 is fixedly connected to the right side of the movable plate 105, and the right side of the spring 107 is fixedly connected to the right side of the inner wall of the mounting block 104.

[0031] Furthermore, the spring 107 prevents the moving plate 105 from sliding and getting stuck. The elastic structure of the spring 107 eliminates the need for manual reset, simplifying the opening and closing process of the cable management plate 7, improving the convenience of cable management, and ensuring the structure is durable and has a low failure rate.

[0032] Please see Figure 1-8 A toothed plate 108 is fixedly connected to the right side of the movable plate 105. A control gear 109 is meshed on the front side of the toothed plate 108. A movable sleeve 1010 is fixedly connected to the top of the control gear 109. An installation sleeve 1011 is fitted on the surface of the movable sleeve 1010. The top of the installation sleeve 1011 is fixedly connected to the top of the inner wall of the mounting block 104.

[0033] Furthermore, by setting the toothed plate 108 and the control gear 109, the running position of the movable sleeve 1010 and the control gear 109 can be limited, ensuring the stability of the gear meshing transmission. The rotation of the gear can drive the toothed plate 108 to move laterally, accurately controlling the movement stroke of the moving plate 105 and the pin 103, realizing the precise unlocking and locking of the cable management mechanism 10. The transmission adjustment accuracy is high, the operation feel is smooth, and it is not easy to jam or misalign.

[0034] Please see Figure 1-8The bottom of the control gear 109 is provided with a fitting groove 1012, and the bottom of the fitting groove 1012 is provided with a fitting block 1013. The top of the fitting block 1013 is fixedly connected with a lifting rod 1014. The top of the lifting rod 1014 extends through to the top of the mounting block 104, and the surface of the lifting rod 1014 is in active contact with the inside of the control gear 109 and the movable sleeve 1010.

[0035] Furthermore, by setting the fitting groove 1012 and the fitting block 1013, the fitting and separation states of the fitting block 1013 and the fitting groove 1012 can be flexibly controlled. Only when the fitting is locked can the lifting rod 1014 drive the control gear 109 to rotate. When it is not locked, the gear remains fixed, which can prevent the cable management mechanism 10 from being accidentally unlocked by external force, improve the stability of the cable management plate 7, and effectively prevent the cable from becoming loose and scattered during daily operation.

[0036] Please see Figure 1-8 A knob 1015 is fixedly connected to the top of the lifting rod 1014. The knob 1015 is located on the top of the mounting block 104. A through groove 1016 is provided on the right side of the mounting block 104. The through groove 1016 is located on the right side of the toothed plate 108.

[0037] Furthermore, the knob 1015 allows operators to manually lift and rotate it, enabling the unlocking and resetting of the cable management mechanism 10 without the need for auxiliary tools. The through slot 1016 provides ample space for the movement of the toothed plate 108, preventing the mounting block 104 from obstructing or limiting the displacement of the toothed plate 108, ensuring smooth operation of the gear and rack transmission structure, further simplifying the operation process of cable management and improving work efficiency.

[0038] Please see Figure 1-8 A stabilizing plate 11 is fitted onto the surface of the output end of the motor 910, and the front side of the stabilizing plate 11 is fixedly connected to the rear side of the integrated management cabinet 1.

[0039] Furthermore, by setting the stabilizing plate 11, the vibration offset generated during the operation of the motor 910 can be reduced, and the meshing misalignment and wear problems of the transmission gear 911, toothed belt 912 and helical tooth structure caused by vibration can be reduced, effectively improving the operating stability of the motor 910 transmission system, extending the service life of transmission components, reducing the frequency of equipment failures, and ensuring the long-term stable operation of the heat dissipation mechanism.

[0040] The specific implementation process of this invention is as follows: During normal use, the pin 103 is inserted into the slot 102 of the socket 101, and together with the mounting block 104, the cable management plates 7 on both sides are locked and fixed, ensuring the cable management plates 7 are stably attached to the top of the cable management base 6, thus confining the wiring of the integrated management equipment 3 inside the cable tray 8. When it is necessary to organize, repair, or lay the equipment wiring, the cable management plates 7 need to be unlocked. The operator pulls the knob 1015 upwards, and the knob 1015 drives the lifting rod 1014 and the locking block 1013 to move synchronously upwards. The upward movement causes the fitting block 1013 to engage with the fitting groove 1012 at the bottom of the control gear 109, completing the engagement and locking of the control gear 109 and the lifting rod 1014, allowing them to rotate synchronously. Rotating the knob 1015 causes the control gear 109 to rotate as a whole via the lifting rod 1014. The outer side of the control gear 109 meshes with the gear plate 108, driving the gear plate 108 to move to the right. The gear plate 108 moves outward through the through groove 1016 on the right side of the mounting block 104, and the movement of the gear plate 108 drives the moving part of the control gear 109 to rotate. The moving plate 105 slides to the right synchronously, and the moving plate 105 moves laterally along the surface of the round rod 106. At the same time, it compresses the spring 107 on the surface of the round rod 106, causing the spring 107 to be in a compressed and stored state. As the moving plate 105 moves to the right, it also drives the end pin 103 to move to the right synchronously, so that the pin 103 completely retracts from the slot 102 of the socket 101, releasing the locking relationship between the socket 101 and the mounting block 104. The fixing constraints of the cable management plates 7 on both sides are completely released, and the cable management plates 7 can be flipped open to the side away from the cable management base 6. The equipment wiring inside the integrated management cabinet 1 is neatly arranged in the cable tray 8 of the cable management seat 6 to complete the wiring sorting, arrangement and maintenance. After the wiring is laid out, the cable management plate 7 is flipped back to reset and fit against the cable management seat 6. The knob 1015 is released, the spring 107 rebounds and pushes the moving plate 105 to reset to the left, driving the pin 103 to re-insert into the slot 102, locking the socket 101 and the mounting block 104 again, so that the cable management plate 7 firmly presses the wiring, realizing the neat binding and fixation of the wiring inside the cabinet, and avoiding the wiring from being messy and tangled. After the internal wiring is centralized and organized, the wire harness is prone to heat accumulation. To prevent the wiring from overheating and aging and to ensure stable equipment operation, an overheat protection mechanism 9 is used to achieve active heat dissipation. The motor 910 at the rear of the integrated management cabinet 1 is started. The output of the motor 910 drives the corresponding transmission gear 911 to rotate. Through the meshing of the toothed belt 912, the transmission gear 911 at the end of the drive shaft 99 rotates synchronously, achieving synchronous power output. The rotation of the drive shaft 99 drives the second drive helical gear 98 to rotate synchronously. The second drive helical gear 98 meshes with the first drive helical gear 97, converting lateral power into longitudinal power, driving the drive shaft 96 to rotate as a whole. The drive shaft 96 drives the second driven helical gear 95 at the rear to rotate. 5 engages with the driven helical gear 94, ultimately driving the fan 93 inside the mounting base to rotate at high speed. The upper fan 93 inside the air inlet duct 5 and the lower fan 93 at the bottom of the cabinet operate synchronously. The top fan 93 sends cooling air into the integrated management cabinet 1, driving the airflow inside the cabinet to flow from top to bottom. The bottom fan 93 further accelerates the air circulation inside the cabinet, enhancing the airflow effect. The high-speed airflow precisely blows on the wire harness area fixed by the cable management base 6 and the cable management plate 7, quickly removing the heat accumulated in the wire harness, solving the heat accumulation problem caused by the concentrated arrangement of lines, realizing heat dissipation and cooling of the lines inside the cabinet, preventing the wire harness from overheating and being damaged, and ensuring the long-term stable operation of the power quality integrated management equipment 3 of the power distribution network.
