Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and in particular to an energy-saving power cabinet. Background Art

[0002] Energy-saving power cabinets are electrical devices that integrate intelligent control and efficient power management. Through technologies such as dynamic voltage adjustment, power factor optimization, and real-time load monitoring, they achieve refined management of power distribution and improve system energy efficiency. Their core technologies include a deep integration of hardware and software. At the hardware level, they employ high-efficiency components such as low-loss transformers and energy-saving circuit breakers, combined with a modular design to enhance scalability. At the software level, they integrate an energy management system, support remote monitoring and data analysis, and implement fault warning and self-healing through edge computing. Existing power cabinets require heat dissipation during use, typically through cooling fans. However, these have the following drawbacks in practice: First, power cabinets are typically semi-enclosed, with only cooling troughs. Prolonged use of cooling fans results in high energy consumption and increases the temperature in the fan area, potentially causing equipment failures.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-10 The present invention provides a technical solution: an energy-saving power cabinet, comprising a power cabinet body 1 and a telescopic motor 710, a first cabinet door 2 and a second cabinet door 3 being installed on the front side of the power cabinet body 1, heat dissipation slots 4 being arranged in an array on the upper ends of the left and right sides of the power cabinet body 1, dustproof frames 5 being fixedly installed on the heat dissipation slots 4, and two sets of rainproof roofs 6 being provided on the upper side of the power cabinet body 1;

[0034] The heat dissipation mechanism 7 includes a second movable piece 703 and a mounting rotating plate 708. The second movable piece 703 is movably mounted on the upper side of the power cabinet body 1. There are two sets of mounting rotating plates 708 that are movably mounted on the second movable piece 703.

[0035] Double expansion mechanism 8, the double expansion mechanism 8 includes an arc block 801 and a solar panel 806, the arc block 801 is fixedly mounted on the lower side of the mounting rotating plate 708, and the solar panel 806 is movably mounted on the mounting rotating plate 708;

[0036] Shielding mechanism 9, shielding mechanism 9 includes shielding side plates 902 and flow slots 903. Shielding side plates 902 are provided with flow slots 903 in an array. The positions of flow slots 903 are opposite to the positions of heat dissipation slots 4.

[0037] A mounting plate 13 is fixedly installed in the power cabinet 1, and a cooling fan 14 is installed in an array on the mounting plate 13. The device has three states when in use: Figure 1 In the normal state shown, the upper side of the power cabinet body 1 is closed but the heat dissipation slots 4 remain open, ensuring top protection while meeting basic ventilation requirements; Figure 4 In the cooling state shown, the telescopic motor 710 drives the first and second movable plates 702 and 703 to extend, leaving the upper cabinet and heat sink 4 open, creating an upward and downward convection channel and cooperating with the cooling fan 14 for efficient heat dissipation. When protection is required, the device enters the closed state, with the shielding side panels 902 lowered to seal the heat sink 4 and the top movable plate closed, effectively blocking moisture and dust. Furthermore, the device collects electricity via solar panels 806 during periods of abundant sunlight. This electricity is then stored in solar modules 807 and used to power components such as the telescopic motor 710, achieving energy conservation. When not in use, the solar panels 806 can be stored in the storage slot 805 to prevent contamination and corrosion. This state switching and structural linkage achieves a coordinated and unified approach to heat dissipation, protection, and energy utilization.

[0038] Furthermore, the heat dissipation mechanism 7 also includes a fixed plate 701, a first movable plate 702, a first installation axis 709, a limiting hole 705, a limiting rod 706, a sealing gasket 707 and a telescopic motor 710. There are two groups of fixed plates 701. The fixed plates 701 are fixedly installed on the left and right sides of the upper end of the power cabinet body 1. The first movable plate 702 is movably provided on the opposite side of the fixed plate 701. The two groups of fixed plates 701 and the opposite sides of the two groups of first movable plates 702 are provided with a snap-fitting groove 704. The snap-fitting groove 704 is provided with two groups of limiting holes 705. The outer sides of the first movable plate 702 and the second movable plate 703 are fixedly installed with two groups of limiting rods 706. The limiting rods 706 are movably inserted in the limiting holes 705. The outer sides of the movable piece 703 and the first movable piece 702 are adapted to the shapes of the opposite sides of the first movable piece 702 and the fixed piece 701. The shapes of the first movable piece 702 and the second movable piece 703 are adapted to the shape of the upper side of the power cabinet body 1. Sealing gaskets 707 are fixedly installed on the front and rear sides of the first movable piece 702 and the second movable piece 703. Two sets of first mounting shafts 709 are fixedly installed on the second movable piece 703. The mounting rotating plate 708 is rotatably mounted on the first mounting shaft 709. The rainproof top 6 is fixedly installed on the upper side of the mounting rotating plate 708. The telescopic motor 710 is fixedly installed at the center position of the mounting plate 13. The output rod of the telescopic motor 710 is located on the lower side of the second movable piece 703. The schematic diagram of this structure is as follows: Figure 5 、 Figure 6 and Figure 9 The design allows the first and second movable flaps 702, 703 covering the power cabinet body 1 to unfold sequentially, thereby providing ventilation for the upper side of the cabinet. When the temperature inside the cabinet is high, opening both flaps creates a heat dissipation channel, reducing the frequency of activation of the cooling fan 14 and effectively reducing energy consumption. Furthermore, the mounting plate 708 and rainproof roof 6 configured within the structure provide shielding and protection for the upper side of the cabinet body when the flaps are unfolded, preventing rainwater from seeping in. This improves heat dissipation efficiency while ensuring stable operation of the equipment.

[0039] Furthermore, the double-expansion mechanism 8 further includes a hinged rod 803, a movable slot 802 and a movable block 804. The two sets of arc blocks 801 are hinged with a hinged rod 803, and a movable slot 802 is provided on the second movable piece 703. The arc block 801 moves in the movable slot 802. The two sets of hinged rods 803 are hinged on the movable block 804, and the movable block 804 is arranged on the upper side of the telescopic motor 710. The schematic diagram of this structure is as follows: Figure 6 The design allows the mounting plate 708 to move the solar panels 806 as it rises, leaving ample space for the solar panels 806 to unfold. When the solar panels 806 are unfolded, they form an M-shaped shielding structure that effectively covers the first and second movable panels 702, 703, preventing dust and other impurities from entering the power cabinet 1, further improving the stability of equipment operation.

[0040] Furthermore, the double-expansion mechanism 8 also includes a placement groove 805, a solar module 807, a guide frame 808, a first guide rod 809, a sliding block 810, a second installation shaft 811, a first rotating block 812 and a second rotating block 813. The lower sides of the two sets of installation rotating plates 708 are provided with a placement groove 805, and the solar panel 806 is rotatably installed in the placement groove 805. One side of the two sets of solar panels 806 is fixedly installed with a solar module 807. Four sets of guide frames 808 are fixedly installed on the upper side of the power cabinet body 1. The first guide rod 809 is fixedly installed in the guide frame 808. The sliding block 810 is movably sleeved on the first guide rod 809. The second installation shaft 811 is fixedly installed on the sliding block 810. The first rotating block 812 is rotatably installed on the four sets of second installation shafts 811. The second rotating block 813 is movably installed on the upper side of the first rotating block 812. The second rotating block 813 is set at the rotating shaft of the solar panel 806. The schematic diagram of this structure is as follows: Figure 7 and Figure 10This design enables the coordinated deployment of mounting plate 708 and solar panel 806. When mounting plate 708 is driven to deploy, solar panel 806 simultaneously rotates out of its underlying storage slot 805. Solar module 807, which integrates control and power storage components, directly powers retractable motor 710, creating an autonomous energy supply. When not in use, solar panel 806 can be completely stored within storage slot 805, effectively protecting it from dust and moisture. This structural linkage and storage protection design improves energy efficiency while ensuring component life and device stability.

[0041] Furthermore, the double-expansion mechanism 8 also includes a mounting frame 814, a first transmission pinion 815, a first transmission gearwheel 816, a second rotating pinion 817, a second transmission gearwheel 818 and a fixed shaft 819. Two sets of mounting frames 814 are fixedly mounted on a set of mounting rotating plates 708. The first transmission pinion 815 is rotatably mounted in the mounting frame 814. One side of the first transmission pinion 815 is engaged with the first transmission gearwheel 816. The first transmission gearwheel 816 is rotatably mounted in the mounting frame 814. The second rotating pinion 817 is fixedly mounted on the first transmission gearwheel 816. One side of the second rotating pinion 817 is engaged with the second transmission gearwheel 818. A fixed shaft 819 is fixedly mounted on the second transmission gearwheel 818. The fixed shaft 819 is rotatably mounted in the mounting frame 814. The first transmission pinion 815 is fixedly connected to the rotating shaft of the solar panel 806, and the fixed shaft 819 is fixedly connected to the second rotating block 813. The schematic diagram of this structure is as follows: Figure 7 and Figure 8 , the rotation angle of the installation rotating plate 708 is less than ninety degrees, while the solar panel 806 needs to have a good angle facing the sun, and its rotation angle needs to be greater than ninety degrees. The second rotating pinion 817 and the first transmission pinion 815 have the same specifications, the first transmission gear 816 and the second transmission gear 818 have the same specifications, and the number of teeth and diameter of the first transmission pinion 815 are both smaller than the first transmission gear 816. Through the staggered engagement of gears with different numbers of teeth, the solar panel 806 can be rotated to a larger angle, thereby enabling the solar panel 806 to obtain a better angle facing the sun and improve power generation efficiency. When not in use, the solar panel 806 can also be stored in the placement slot 805 to avoid damage from external environmental factors, further increasing the stability of the equipment during use.

[0042] Furthermore, the double-expansion mechanism 8 further includes a limit frame 820, a movable rod 821, a first spring 822 and a rubber block 823. The limit frame 820 is fixedly mounted on the second rotating block 813, and the movable rod 821 is fixedly mounted on the first rotating block 812. The movable rod 821 is movably inserted into the limit frame 820. The first spring 822 is sleeved on the movable rod 821. One side of the first spring 822 is against the limit frame 820. A rubber block 823 is fixedly mounted on one side of the guide frame 808. The schematic diagram of the structure is as follows: Figure 7 After the installation turntable 708 and the solar panel 806 are unfolded, if the output shaft of the telescopic motor 710 continues to rise, it will drive the first movable piece 702 and the second movable piece 703 of the heat dissipation mechanism 7 to open in sequence. At this time, the first rotating block 812 and the second rotating block 813 can move relative to each other through the movable plug-in structure, flexibly adapting to the lifting process of the installation turntable 708 and the solar panel 806, avoiding interference problems caused by the intersection of the movement trajectories of the components. When the two are in the vertical extreme position, the sliding block 810 contacts and squeezes the rubber block 823 in the guide frame 808. This contact force can provide the sliding block 810 with the initial guiding force when the mechanism is restored, ensuring that each component is reset according to the established trajectory, effectively improving the structural stability and movement coordination of the equipment during complex movement.

[0043] Furthermore, the shielding mechanism 9 also includes a fixed frame 901, a mounting block 904, a second guide rod 905 and a second spring 906. The fixed frame 901 is fixedly mounted on the output rod of the telescopic motor 710. Four sets of mounting blocks 904 are fixedly mounted on opposite sides of the shielding side plate 902. A second guide rod 905 is fixedly mounted between the two vertical sets of mounting blocks 904. The end of the fixed frame 901 is movably sleeved on the second guide rod 905. A second spring 906 is sleeved on the second guide rod 905. The lower side of the second spring 906 is against the fixed frame 901. The schematic diagram of this structure is as follows: Figure 9 This design ensures that when the heat dissipation mechanism 7 and the dual-expansion mechanism 8 are in operation, the movement of the fixed frame 901 will not interfere with the position of the shielding side panels 902. The fixed frame 901 and the movable block 804 only maintain abutment, not a fixed connection. When the output shaft of the telescopic motor 710 retracts, the two automatically separate, allowing the shielding side panels 902 to precisely fall and seal the heat dissipation slots 4, ensuring that the power cabinet body 1 is in a completely enclosed state. This non-rigid connection structure effectively isolates the external moisture and dust, providing reliable protection for the electronic components inside the cabinet even in complex environments, significantly improving the environmental adaptability and long-term operational stability of the equipment.

[0044] Furthermore, the fixed frame 901 is fitted with the lower side of the movable block 804, the lower end of the shielding side plate 902 is located at the upper end of the lowermost heat dissipation slot 4, and the distance between the two sets of flow slots 903 is greater than the width of the shielding side plate 902; the schematic diagram of this structure is as follows: Figure 9 This design allows the shielding side panels 902 to completely shield the heat sink 4 when moving downward, significantly shortening the travel required for the shielding side panels 902. By optimizing the transmission structure and guiding mechanism, the shielding side panels 902 can completely cover the heat sink 4 without requiring significant movement. This ensures a sealed seal while improving the efficiency of the mechanism, effectively reducing the risk of external moisture and dust entering the cabinet through the heat sink 4 and enhancing the equipment's protection in complex environments.

[0045] Furthermore, the mounting plate 13 is fixedly mounted on the lower end of the lowermost heat dissipation slot 4, and an array of flow holes 15 are provided at the edge of the mounting plate 13; the schematic diagram of the structure is as follows: Figure 3 The cooling fan 14 is oriented downward, with its air inlet positioned adjacent to the heat sink 4 and the upper surface of the power cabinet 1. This arrangement allows cool air to be quickly drawn in directly through the heat sink 4. The openings 15 are offset from the direction of the cooling fan 14. By leveraging the principle of rising hot air, a natural convection channel is formed at the bottom of the cabinet. This allows the hot air exhausted by the fan to interact with the rising hot air inside the cabinet, significantly improving air exchange efficiency. This not only shortens the cooling cycle, but also reduces energy consumption through structural optimization, ensuring timely heat dissipation from within the cabinet and maintaining a stable operating environment for electronic components.

[0046] Furthermore, a humidity detector 10 is fixedly installed on the front side of the second cabinet door 3, a temperature detector 11 is fixedly installed on the inner side of the second cabinet door 3, and a waterproof cloth 12 is fixedly installed between the two sets of rainproof roofs 6. The edge of the rainproof roof 6 exceeds the edge of the power cabinet body 1. The schematic diagram of this structure is as follows: Figure 1 and Figure 2 This design enables the humidity detector 10 and temperature detector 11 to automatically control the operation of the telescopic motor 710 based on real-time environmental data. When the external humidity exceeds a preset threshold, the system will keep the heat dissipation mechanism 7 closed to prevent moisture from entering the cabinet. If the internal temperature of the power cabinet 1 is detected to be too high, the telescopic motor 710 will automatically trigger the heat dissipation mechanism 7 to expand, forming an efficient heat dissipation channel. This intelligent control logic based on sensor feedback enables automated and adaptive operation of the equipment, effectively improving the system's reliability under various environmental conditions.

[0047] Furthermore, a waterproof sheet 12 spans the two rainproof roofs 6 and securely connects their edges, completely covering the gap formed at the top when the rainproof roofs 6 are deployed. Made of a flexible, weather-resistant material, this sheet 12 deforms freely as the angle of deployment of the rainproof roofs 6 changes, maintaining a sealed seal around the upper opening of the cabinet, preventing rainwater from seeping in even during heavy rain. Through the coordinated design of the detection elements and protective structure, the equipment not only achieves intelligent heat dissipation control, but also further enhances its overall waterproof performance through the dynamic sealing properties of the sheet 12, protecting internal electronic components from the harsh external environment.

[0048] Working principle: When the heat dissipation mechanism 7 of the present invention is used, the output rod of the telescopic motor 710 is extended. At this time, the fixed frame 901 rises and drives the movable block 804 to rise. The hinged rod 803 gradually drives the arc block 801 to rotate horizontally, thereby driving the installation rotating plate 708 to rotate. When the installation rotating plate 708 rotates, the first rotating block 812 and the second rotating block 813 will be driven to gradually become vertical, thereby causing the fixed shaft 819 and the second rotating pinion 817 to rotate, and then drive the first transmission pinion 815 to rotate through engagement, so that the solar panel 806 is rotated out of the placement slot 805. Since the hinged rod 803 will abut against the movable slot 802, the installation rotating plate 708 will no longer rotate after rotating to a certain angle, and drive the second movable piece 703 to rise. After the second movable piece 703 rises to a certain height, the limiting rod 706 abuts against the lower side of the limiting hole 705, driving the first movable piece 702 to rise until it reaches Figure 4 When the rotating plate 708 is installed and raised, the first rotating block 812 and the second rotating block 813 will rotate to a completely vertical state, and the first rotating block 812 will move relative to the limit frame 820 and compress the first spring 822. The sliding block 810 will squeeze the rubber block 823 to a certain extent. When the fixed frame 901 rises, the shielding side plate 902 and the fixed plate 701 are abutted, so that the fixed frame 901 can move along the second guide rod 905 and compress the second spring 906. When it is restored, the telescopic motor 71 0's output rod retracts, the fixed frame 901 returns to its original position, and the movable block 804 descends under the action of gravity, causing the installation turn plate 708 to rotate to a horizontal position. When the installation turn plate 708 rotates, the sliding block 810 will gradually move back to its original position, and the relative positions of the limit frame 820 and the movable rod 821 will also be aligned under the action of the first spring 822. When the second rotating block 813 rotates, the solar panel 806 will be retracted into the placement groove 805, the second movable piece 703 will meet on the first movable piece 702, and the first movable piece 702 will meet on the fixed piece 701, thereby closing the upper end of the power cabinet body 1.

[0049] When the heat dissipation slot 4 needs to be closed, the output rod of the telescopic motor 710 is shortened, the fixed frame 901 is separated from the movable block 804, and the fixed frame 901 drives the shielding side plate 902 to descend, so that the shielding side plate 902 shields the heat dissipation slot 4, completing the complete closure of the power cabinet body 1, and vice versa, it can be restored.
