DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] Reference Figure 1-11 An outdoor low-voltage distribution cabinet for an electric power system comprises a base 1, a threading groove 16 is arranged at the bottom of the base 1, a movable frame mechanism 10 which can be lifted and lowered is arranged above the base 1, and four vertically distributed rectangular conduits 12 are installed inside the movable frame mechanism 10, and the sides of the rectangular conduits 12 are provided with positioning grooves distributed at equal distances, and multiple layers of bearing mechanisms 11 for fixing electrical components are arranged between the four rectangular conduits 12, and two rows of push-pull adjustable electrical component installation components 115 are arranged in the bearing mechanism 11, and four vertically distributed rectangular conduits 12 are installed inside the base 1. A rectangular sleeve 18 is slidably connected to the bottom of the rectangular duct 12, and rotating motors 9 are installed at both ends of the base 1, and a cabinet 8 with a door-type structure is installed between the output shafts of the two rotating motors 9. A top cover 6 is provided on the top of the cabinet 8, and two cabinet doors 7 are hinged on both sides of the cabinet 8. A sealing strip 3 that is compatible with the connection between the base 1 and the movable frame mechanism 10 is provided at the bottom of the cabinet door 7. Two liftable locking mechanisms 15 are installed inside the top cover 6, and a locking rod 152 that is interlaced and connected to the space of the rectangular duct 12 is provided at the bottom of the locking mechanism 15.

[0021] In the present invention, the cabinet body 8 is a door-shaped frame structure, and both sides of the cabinet body 8 are provided with cabinet doors 7 that can be opened and closed. When the cabinet doors 7 are opened, the cabinet body 8 is rotated by the rotating motor 9. When the inside of the power distribution cabinet needs to be maintained, the cabinet body 8 is rotated to a vertical position, so that the supporting mechanism 11 carrying the electrical components can be exposed to the outside as a whole. Secondly, the movable frame mechanism 10 is located above the base 1. The movable frame mechanism 10 is lifted off the base 1 to expose the wires at the bottom, thereby expanding the wiring maintenance space for the wires entering and leaving the power distribution cabinet. At the same time, the supporting mechanism The structures 11 are arranged in multiple layers on the four rectangular conduits 12 for plugging and unplugging, and the spacing between each layer of the bearing mechanisms 11 can be lifted and adjusted. Secondly, two rows of push-pull adjustable electrical component installation assemblies 115 are provided in the bearing mechanism 11. The electrical components can be arranged alternately in two rows to increase the wiring space. When the electrical components need to be maintained, the corresponding electrical component installation assemblies 115 are pulled out to effectively free up the space on both sides of the electrical components, so that the electrical components on each layer of the bearing mechanism 11 have sufficient operating space, effectively improving the efficiency of the maintenance of the distribution cabinet.

[0022] As a further solution in the present invention, heat dissipation mesh plates 2 are provided on both sides of the base 1, and a filter screen 17 is installed on the inner side of the heat dissipation mesh plate 2, and an air duct facing the threading groove 16 is provided at the outlet of the filter screen 17. The interior of the top cover 6 is a cavity structure, and an exhaust groove 13 facing the cabinet door 7 is provided at the bottom edge of the top cover 6, and an exhaust fan 14 is installed at the bottom center of the top cover 6. In the present invention, when heat is generated inside the distribution cabinet, cold and hot air convection draws cold air in from the bottom. At the same time, through the setting of the air duct, the cold air rises layer by layer through the wire gap at the threading groove 16, effectively cooling the electrical components inside the distribution cabinet. When the temperature inside the low-voltage distribution cabinet is high, the exhaust fan 14 is turned on to force the inside of the distribution cabinet to circulate, and the exhaust groove 13 is directed toward the cabinet door 7. When the air is ejected from the exhaust groove 13, a wind curtain is formed on the outside of the cabinet door 7 to prevent dust from approaching the cabinet door 7 and at the same time, accelerate the heat dissipation effect at the cabinet door 7.

[0023] As a further solution in the present invention, a support shaft 5 is installed on the top of the top cover 6, and a solar mechanism 4 with an adjustable angle is installed on the outside of the support shaft 5. A battery electrically connected to the solar mechanism 4 is also installed inside the top cover 6. In the present invention, under daylight conditions, the solar mechanism 4 is used to power the exhaust fan 14 and charge the battery to store energy, thereby effectively reducing the energy consumption of heat dissipation in the distribution cabinet. At the same time, the exhaust volume of the exhaust fan 14 can also be adjusted according to the light intensity to protect the electrical components inside the distribution cabinet.

[0024] As a further solution in the present invention, the solar mechanism 4 includes a solar panel 41 that rotates around a support shaft 5, and an arc-shaped rack 42 installed at the bottom of the solar panel 41. The solar mechanism 4 also includes an adjusting motor 44 installed inside the top cover 6, and a gear 43 that meshes with the arc-shaped rack 42 is installed at the end of the output shaft of the adjusting motor 44. In the present invention, the solar panel 41 can be driven to rotate around the support shaft 5 by adjusting the motor 44, thereby adjusting the shielding angle of the solar panel 41 on the top of the distribution cabinet, reducing the impact of wind, rain and sunlight on the distribution cabinet, and improving the power generation efficiency of the solar panel 41.

[0025] As a further solution in the present invention, the movable frame mechanism 10 includes a frame support 101, and both ends of the frame support 101 are provided with support foot assemblies 102 connected to the base 1, four rectangular ducts 12 are respectively installed at the four corners of the frame support 101, and a plurality of wire management plates 103 are embedded at the bottom of the frame support 101, and the edges of the wire management plates 103 are provided with spliced ​​wire threading holes 104. In the present invention, the wires of the distribution cabinet pass through the wire threading holes 104 and enter the area where the bearing mechanism 11 is located, and the remaining wires are arranged in the upper and lower areas of the wire management plates 103. During wire management maintenance, the movable frame mechanism 10 can be lifted as a whole by the support foot assembly 102, and the operating space between the base 1 and the movable frame mechanism 10 is expanded, providing convenience for the maintenance of the wires at the bottom of the distribution cabinet.

[0026] As a further solution in the present invention, the support foot assembly 102 includes a rectangular support member 1021 installed on the base 1, and an L-shaped support foot 1022 installed on the frame bracket 101, a threaded screw 1023 is rotatably installed in the middle of the L-shaped support foot 1022, and a motor 1024 for driving the threaded screw 1023 is installed on the frame bracket 101, a ball nut threadedly connected to the threaded screw 1023 is installed inside the rectangular support member 1021, and the L-shaped support foot 1022 is slidably connected to the rectangular support member 1021. In the present invention, the movable frame mechanism 10 is firmly supported by the L-shaped support foot 1022 and the rectangular sleeve 18. When the motor 1024 drives the threaded screw 1023 to rotate, the movable frame mechanism 10 and the structure above it can be driven to lift as a whole.

[0027] As a further solution in the present invention, the locking mechanism 15 includes a locking bracket 151 slidably installed at the bottom of the cover body 6, and the locking rod 152 is installed at the two end positions of the locking bracket 151.

In the present invention, when the cabinet body 8 is in a closed state to protect the distribution cabinet, the locking bracket 151 is pulled downward so that the four locking rods 152 are respectively inserted into the upper ends of the four rectangular guide tubes 12, so that the cabinet body 8, the rectangular guide tube 12, the movable frame mechanism 10 and the base 1 are connected to form an integral structure, providing stable protection for the structure inside the cabinet.

[0028] As a further solution in the present invention, the supporting mechanism 11 includes a supporting frame 111 slidably connected to four rectangular tubes 12, and positioning components 114 engaged with the positioning grooves are provided at both ends of the supporting frame 111, a rectangular wire groove 112 is provided in the middle position of the supporting frame 111, and rectangular installation grooves 113 are provided on both side edges of the supporting frame 111, and electrical component installation components 115 are inserted into the rectangular installation grooves 113. In the present invention, the wires are inserted through the wire grooves 112 for wiring. At the same time, the spacing between the upper and lower supporting mechanisms 11 is adjusted by the cooperation of the positioning components 114 and the positioning grooves. The electrical component installation components 115 are arranged on both sides of the supporting frame 111 through the rectangular installation grooves 113. When the electrical component installation components 115 are pulled out, they can be staggered with the adjacent ones, thereby increasing the operating space of the electrical component installation components 115.

[0029] As a further solution of the present invention, the electrical component installation assembly 115 includes a horizontally arranged insertion plate 1151, and a vertical bearing plate 1152 sleeved on the outside of the insertion plate 1151, an electrical component mounting frame 1154 is arranged on the side of the vertical bearing plate 1152, and an arc-shaped sleeve 1153 for threading is also embedded on the side of the vertical bearing plate 1152, and a buckle lock connected to the bearing frame 111 is arranged at the end of the insertion plate 1151. In the present invention, the electrical components can be installed when the electrical components are disassembled. When the component 115 is pulled out, the vertical supporting plate 1152 can be separated from the insertion plate 1151, exposing the wiring area at the rear end of the electrical component installation component 115, which significantly improves the wiring efficiency of the distribution cabinet. After the electrical components are disassembled and assembled, the electrical component installation component 115 can be pushed in and fixed, and effectively fixed with a snap lock. The electrical component installation component 115 is arranged in two rows, front and back, so that electrical components can be arranged on both sides of the distribution cabinet.

In the present invention, the staff rotates the movable part 1142 outward, and the L-shaped positioning pins 1143 are pulled out from the inside of the positioning groove, so as to adjust the height of the upper and lower layers of the supporting mechanism 11. When the adjustment is completed, the movable part 1142 is close to the rectangular guide tube 12 under the action of the torsion spring 1141, and the locking operation of the position of the supporting mechanism 11 is completed, and the adjustment is simple and convenient.

[0031] When in use, the cabinet door 7 is opened and the cabinet body 8 is rotated by the rotating motor 9. When maintenance is required inside the distribution cabinet, the cabinet body 8 is rotated to a vertical position, so that the supporting mechanism 11 carrying the electrical components can be exposed to the outside as a whole. Secondly, the movable frame mechanism 10 is located above the base 1. The movable frame mechanism 10 can be lifted off the base 1 to expose the wires at the bottom, thereby expanding the wiring maintenance space for the wires entering and exiting the distribution cabinet. At the same time, the supporting mechanism 11 is arranged in multiple layers on four rectangular conduits 12 for plugging and unplugging, and the spacing between each layer of the supporting mechanism 11 can be lifted and adjusted. Secondly, two rows of push-pull adjustable electrical component installation assemblies 115 are provided in the supporting mechanism 11. The electrical components can be arranged alternately in two rows to increase the wiring space. When maintenance is required on the electrical components, the corresponding electrical component installation assemblies 115 are pulled out to effectively free up the space on both sides of the electrical components, so that the electrical components on each layer of the supporting mechanism 11 have sufficient operating space.
