Description

An outdoor quick-assembly distribution cabinet

[0001] The present invention relates to an assembled power distribution cabinet, in particular to an outdoor quick-assembled power distribution cabinet, and belongs to the technical field of power distribution cabinet equipment.

[0002] The distribution cabinet is the final equipment of the power distribution system. The distribution cabinets on both sides of the road can distribute electricity to different electrical equipment such as lighting systems, camera systems, and traffic light systems to meet the power needs of each system. When the circuit of any system fails, these protection devices will immediately cut off the power supply to avoid further damage to the equipment and ensure the safety of pedestrians and property. The distribution cabinet can also optimize the energy consumption of the electrical system by reasonably adjusting parameters such as current and voltage, which helps to save energy, reduce emissions and protect the environment.

[0003] When installing a distribution cabinet, since traditional distribution cabinets are integrated, welding is usually required in advance, which results in the distribution cabinet occupying a large space. The number of cabinets transported at a time is limited, and it is easy to be bumped and deformed during transportation, which increases transportation costs. In addition, the existing modular distribution cabinets need to be assembled and fixed with wrenches or welding guns, which is bound to waste a lot of time and labor costs, and the assembly efficiency is low.

[0028] The present invention has at least the following beneficial effects:

[0029] 1. The distribution cabinet base, support columns, sealing side panels and positioning fixing plates on the distribution cabinet are transported in categories to ensure quality while reducing transportation costs. During installation, the sealing side panels are placed between the distribution cabinet base and the distribution cabinet top plate, and then the distribution cabinet top plate is pressed against the upper end of the support column.

[0030] 2. When the brake magnet approaches the magnet fixed pin brake chamber, the driven magnet inside the magnet fixed pin brake chamber approaches the brake magnet under the action of magnetic force, and fits together under the action of force. The driven magnet enters the interior of the positioning mounting block to fix the positioning fixing plate.

The structure is simple and the efficiency of installation and disassembly is greatly improved.

[0031] 3. Under the action of the fan, air inside the distribution cabinet is extracted from the second through hole, the air pressure inside the distribution cabinet is reduced, and then the air enters the interior of the distribution cabinet from the first through hole, forming a cycle. The circulating airflow brings out the heat inside the distribution cabinet, thereby achieving the purpose of reducing the internal heat of the distribution cabinet. The heat dissipation frame is sealed by the heat dissipation frame sealing plate to ensure the overall sealing of the distribution cabinet top plate and achieve the purpose of heat dissipation.

[0032] 4. Once a certain amount of heat is generated inside the distribution cabinet, the heat-absorbing surface of the semiconductor refrigeration plate will absorb the heat inside the distribution cabinet, and then transfer the heat to the inside of the air inlet through the heat dissipation surface of the semiconductor refrigeration plate. The heat in the air inlet is brought out by the expansion of the air flow or the external air flow, thereby achieving the purpose of reducing the internal heat of the distribution cabinet. A stainless steel grille is fixed at the port of the air inlet to prevent impurities from entering the interior of the air inlet, thereby improving the service life of the semiconductor refrigeration plate.

[0045] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0046] As shown in Figure 10, the outdoor quick-assembly distribution cabinet provided by this embodiment includes a distribution cabinet base 1 and a distribution cabinet top plate 3 connected by a support column 2. A sealing side plate 4 is provided between the distribution cabinet base 1 and the distribution cabinet top plate 3. During the installation process, the support column 2 is fixed to the distribution cabinet base 1, and then the sealing side plate 4 is placed between the distribution cabinet base 1 and the distribution cabinet top plate 3, and then the distribution cabinet top plate 3 is fixed to the upper end of the support column 2. The structure is simple, which is convenient for quick installation of the device, greatly improving the convenience of use and the efficiency of installation. The bottom of the support column 2 is connected to the distribution cabinet base 1 by screwing, and the bottom of the support column 2 is fixedly connected to the distribution cabinet base 1 by a threaded engagement. The bottom of the support column 2 is fixedly connected to the distribution cabinet base 1 by a threaded column 201. No bolts are required, which is convenient for quick installation. A positioning mounting block 202 is fixed on the top of the support column 2. The distribution cabinet top plate 3 includes a heat dissipation frame 6 and a positioning fixing plate 7. The heat dissipation frame 6 is fixedly provided on the upper side of the positioning fixing plate 7.

[0047] During the installation of the top plate 3 of the power distribution cabinet, positioning and mounting holes 701 are provided at the four feet of the lower side of the positioning and fixing plate 7. The positioning and mounting block 202 is engaged with the positioning and mounting holes 701. A brake pin 5 is provided inside the positioning and mounting block 202. The brake pin 5 includes a brake magnet 501 and a pressing column 502 that squeeze each other. When the positioning and mounting hole 701 is engaged with the positioning and mounting block 202, the pressing column 502 on the positioning and mounting block 202 is pressed. When the pressing column 502 brakes downward, the brake magnet 501 is driven to move horizontally.

[0048] The installation process is specifically as follows: the upper end of the pressing post 502 is connected to a pressing plate 506, and a vertical spring 507 is fixedly provided between the pressing plate 506 and the pressing pin brake chamber 204. When the pressing post 502 moves downward, the special-shaped brake block 505 is used to horizontally push the brake magnet brake post 503. When the positioning fixing plate 7 presses the pressing plate 506 on the pressing post 502, the pressing plate 506 drives the pressing post 502 to move downward. When the pressing post 502 moves downward, a special-shaped brake block 505 is fixedly provided on one side of the pressing post 502, and one end of the braking magnet 501 is connected to the braking magnet braking post 503. The braking magnet braking post 503 and the special-shaped brake block 505 are abutted. The special-shaped brake block 505 on the pressing post 502 generates a force on the braking magnet braking post 503 on the braking magnet 501, thereby achieving the effect of pushing the braking magnet 501 outward through the braking magnet braking post 503;

[0049] After the brake magnet 501 is pushed outward, a driving rod compartment 706 corresponding to the magnet guide pin brake compartment 205 is opened inside the positioning fixing plate 7, and a fixing pin 8 is slidably provided inside the driving rod compartment 706. The fixing pin 8 includes a driving rod 801 and a driven magnet 802 corresponding to the brake magnet 501. The driven magnet 802 corresponds to the magnet guide pin brake compartment 205, and the contact surface of the driven magnet 802 and the brake magnet 501 has opposite magnetic properties. When the brake magnet 501 approaches the magnet fixing pin brake compartment 707, the driven magnet 802 inside the magnet fixing pin brake compartment 707 approaches the brake magnet 501 under the action of magnetic force and fits together under the action of force. After the driven magnet 802 and the brake magnet 501 fit together, the driven magnet 802 enters the interior of the positioning mounting block 202, thereby fixing the positioning fixing plate 7.

[0050] The disassembly and assembly process is as follows: one end of the driving rod 801 is connected to the driving rod handle 806, and the outer side of the positioning fixing plate 7 is provided with a driving handle groove 705. The driving rod handle 806 is rotated inside the driving handle groove 705. First, the driven magnet rod 803 on the driven magnet 802 is pushed backward by the driving rod handle 806 on the driving rod 801, and the driving rod handle 806 is rotated clockwise. One end of the driven magnet 802 is connected to the driven magnet rod 803, and the driven magnet rod 803 is provided with a plurality of Evenly distributed driving teeth 804 are arranged on the driving rod 801. One end of the driving rod 801 is fixedly connected to a circular driving post 805. The circular driving post 805 is engaged with the driving teeth 804. The circular driving post 805 is used to horizontally push the driven magnet rod 803. The circular driving post 805 on the driving rod 801 is engaged with the driving teeth 804 on the driven magnet rod 803, thereby being able to move the driven magnet rod 803 to one side, so that the driven magnet 802 moves away from the positioning mounting block 202 and gradually separates from the braking magnet 501.

[0051] When the braking magnet 501 is at a sufficient distance from the driven magnet 802, a transverse spring 504 is fixedly provided between the braking magnet 501 and the magnet guide pin brake chamber 205. When the transverse spring 504 and the positioning fixing plate 7 are not in contact with the positioning mounting block 202, the pressing post 502 moves upward, and the braking magnet 501 moves in the direction away from the driven magnet 802. Under the action of the transverse spring 504, the braking magnet 501 continues to slide toward the inside of the positioning mounting block 202. At the same time, under the action of the vertical spring 507, the braking magnet braking post 503 moves to the side away from the driven magnet 802, and the pressing post 502 moves upward, so that the positioning fixing plate 7 can be easily removed from the support post 2. The structure is simple and the efficiency of installation and disassembly is greatly improved.

[0052] In addition, the interior of the positioning mounting block 202 is provided with a pressing pin brake chamber 204 and a magnet guide pin brake chamber 205 that are interconnected. The pressing column 502 is vertically slidably arranged inside the pressing pin brake chamber 204, and the braking magnet 501 is horizontally slidably arranged inside the magnet guide pin brake chamber 205. When the pressing plate 506 is pressed, the pressing column 502 is slidably arranged inside the pressing pin brake chamber 204, and the vertical spring 507 is fixedly arranged inside the pressing pin brake chamber 204. After the pressure on the pressing plate 506 disappears, the pressing plate 506 protrudes from the upper side surface of the positioning mounting block 202 under the action of the vertical spring 507.

[0053] At the same time, the brake magnet brake column 503 on the brake magnet 501 is slidably arranged inside the magnet guide pin brake compartment 205. The brake magnet brake column 503 on one side abuts against the special-shaped brake block 505, and the brake magnet 501 on the other side is used to attract the driven magnet 802. When the driven magnet 802 enters the interior of the magnet guide pin brake compartment 205, it plays a certain limiting support role, thereby fixing the positioning fixing plate 7 on the support column 2. The structure is simple and easy to operate.

[0054] A magnet fixed pin brake chamber 707 connected to the drive rod chamber 706 is provided at the joint between the positioning fixing plate 7 and the positioning mounting block 202. The driven magnet 802 is slidably arranged inside the magnet fixed pin brake chamber 707. When the drive rod 801 rotates, it drives the driven magnet rod 803 to slide inside the drive rod chamber 706. When disassembly and assembly are required, the driven magnet 802 is pushed into the magnet fixed pin brake chamber 707. The drive rod chamber 706 and the magnet fixed pin brake chamber 707 play a certain guiding and supporting role for the fixing pin 8. After the driven magnet 802 enters the interior of the magnet fixed pin brake chamber 707, it is convenient to remove the positioning fixing plate 7 from the support column 2, so as to facilitate the disassembly and assembly of the positioning fixing plate 7.

[0055] Furthermore, as shown in Figures 5 and 6, a heat dissipation baffle 603 is fixedly provided in the middle of the heat dissipation frame 6, a fan baffle 604 is fixedly provided on one side of the heat dissipation baffle 603, a plurality of evenly distributed fan holes 605 are opened on the fan baffle 604, and a fan 607 is fixedly provided inside the fan hole 605. The heat dissipation baffle 603 divides the heat dissipation frame 6 into two parts, and the fan baffle 604 is provided on one side. The fan 607 is arranged on the fan baffle 604, which can disturb the airflow inside the heat dissipation frame 6;

[0056] A second through hole 704 is provided on one side of the heat dissipation baffle 603 on the positioning and fixing plate 7, and a first through hole 703 is provided on the other side of the heat dissipation baffle 603. The first through hole 703 and the second through hole 704 are connected to the interior of the power distribution cabinet. Under the action of the fan 607 on the fan baffle 604, air inside the power distribution cabinet is extracted from the second through hole 704, and the air pressure inside the power distribution cabinet is reduced. Then, the air enters the interior of the power distribution cabinet from the first through hole 703, forming a cycle. The circulating airflow brings out the heat inside the power distribution cabinet, thereby achieving the purpose of reducing the heat inside the power distribution cabinet. The entire heat dissipation system is on the top plate 3 of the power distribution cabinet. Therefore, as long as the top plate 3 of the power distribution cabinet is installed on the support column 2, the power distribution cabinet can be cooled. The structure is simple and easy to install and use.

[0057] A number of evenly distributed air holes 602 are provided on both sides of the heat dissipation frame 6. The heat extracted through the second through-holes 704 is then discharged to the outside of the power distribution cabinet through the air holes 602. A water barrier 606 is fixedly provided on one side of the air hole 602. A heat dissipation frame sealing plate 601 is fixedly provided on the upper side of the heat dissipation frame 6. A water barrier 606 is fixedly provided inside the heat dissipation frame 6, which can effectively prevent moisture from entering the interior of the power distribution cabinet. At the same time, if there is a small amount of accumulated water, the evaporation of water can accelerate the dissipation of heat. The heat dissipation frame 6 is sealed by the heat dissipation frame sealing plate 601 to ensure the overall sealing of the power distribution cabinet top plate 3 and achieve the purpose of heat dissipation.

[0058] At the same time, as shown in Figures 7 and 8, an air inlet hole 103 is provided inside the base 1 of the distribution cabinet, and a refrigeration film bin 102 connected to the air inlet hole 103 is provided on the upper side of the base 1 of the distribution cabinet. A semiconductor refrigeration film 9 is fixedly provided inside the refrigeration film bin 102. An air inlet hole 103 is provided inside the base 1 of the distribution cabinet, and a semiconductor refrigeration film 9 is fixedly provided in the refrigeration film bin 102 connected to the air inlet hole 103. Therefore, air flow can enter the interior of the refrigeration film bin 102 through the air inlet hole 103. The semiconductor refrigeration film 9 includes a refrigeration film heat dissipation surface 901 and a refrigeration film heat absorption surface 902. The refrigeration film heat dissipation surface 901 is provided on the base of the distribution cabinet. 1, the cooling plate heat absorption surface 902 is arranged inside the air inlet 103. Once a certain amount of heat is generated inside the power distribution cabinet, the cooling plate heat absorption surface 902 on the semiconductor cooling plate 9 will absorb the heat inside the power distribution cabinet, and then transfer the heat to the inside of the air inlet 103 through the cooling plate heat dissipation surface 901 on the semiconductor cooling plate 9. The heat in the air inlet 103 is brought out by the expansion of the air flow or the external air flow, thereby achieving the purpose of reducing the heat inside the power distribution cabinet. A stainless steel grille 107 is fixedly provided at the port of the air inlet 103 to prevent impurities from entering the interior of the air inlet 103, thereby improving the service life of the semiconductor cooling plate 9;

[0059] The heat dissipation frame 6 is used at the top of the power distribution cabinet, and the heat dissipation is carried out at the bottom through the semiconductor cooling plate 9 and the air inlet 103. The structure is simple and the heat dissipation efficiency of the power distribution cabinet is greatly improved.

[0060] Furthermore, as shown in Figures 1 and 4, a threaded column 201 is fixedly provided at the bottom of the support column 2, and a support column threaded hole 101 corresponding to the threaded column 201 is opened on the distribution cabinet base 1. The threaded column 201 and the support column threaded hole 101 are screwed together by screwing. When connecting the support column 2 to the distribution cabinet base 1, the threaded column 201 at the bottom of the support column 2 is screwed to the support column threaded hole 101 on the distribution cabinet base 1. This simplifies the structure and improves the efficiency of installation.

[0061] As shown in Figures 6 and 7, a base positioning groove 104 is provided on the upper side of the distribution cabinet base 1, and a fixing plate positioning groove 702 corresponding to the base positioning groove 104 is provided on the lower side of the positioning fixing plate 7. The upper and lower sides of the sealing side plate 4 are respectively snapped into the base positioning groove 104 or the fixing plate positioning groove 702. The sealing side plate 4 includes a short side plate 401 and a long side plate 402. When installing the sealing side plate 4, the upper and lower sides of the short side plate 401 and the long side plate 402 are respectively fixed in the base positioning groove 104 or the fixing plate positioning groove 702, which can improve the overall stability of the distribution cabinet and ensure the overall sealing of the distribution cabinet.

[0062] A side panel vertical mounting groove 203 is provided on the support column 2, and the left and right side surfaces of the sealing side panel 4 are clamped in the inside of the side panel vertical mounting groove 203, and then the two sides of the short side panel 401 or the long side panel 402 are clamped in the side panel vertical mounting groove 203 of the support column 2, which is also to improve the stability and sealing of the device. A door body groove 403 is provided on one of the long side panels 402, and a door body 10 is rotatably arranged on the door body groove 403 to improve the convenience of use.

[0063] Furthermore, as shown in Figures 7 and 9, the bottom of the distribution cabinet base 1 is fixedly connected to a base support foot 105, and a number of evenly distributed support foot positioning holes 106 are opened on the base support foot 105. The base support foot 105 supports the distribution cabinet base 1 to improve the stability of the distribution cabinet base 1 and at the same time raise the distribution cabinet base 1 to reduce the contact between the distribution cabinet base 1 and the ground. The outer sides of the support column 2, the sealing side panel 4 and the distribution cabinet top panel 3 are sprayed with anti-rust paint to improve the service life of the distribution cabinet base 1.

[0064] As shown in Figure 10, the principles of the outdoor quick-assembly power distribution cabinet provided in this embodiment are as follows:

[0065] The installation process is as follows: when the positioning fixing plate 7 presses the pressing plate 506 on the pressing column 502, the pressing plate 506 drives the pressing column 502 to move downward. When the pressing column 502 moves downward, the special-shaped brake block 505 on the pressing column 502 exerts a force on the brake magnet brake column 503 on the brake magnet 501, thereby achieving the effect of pushing the brake magnet 501 outward through the brake magnet brake column 503;

[0066] After the brake magnet 501 is pushed outward, when the brake magnet 501 approaches the magnet fixed pin brake chamber 707, the driven magnet 802 inside the magnet fixed pin brake chamber 707 approaches the brake magnet 501 under the action of magnetic force, and fits together under the action of force. After the driven magnet 802 and the brake magnet 501 fit together, the driven magnet 802 enters the interior of the positioning mounting block 202, playing the role of fixing the positioning fixing plate 7;

[0067] The disassembly and assembly process is as follows: first, the driven magnet rod 803 on the driven magnet 802 is pushed backward by the driving rod handle 806 on the driving rod 801, and the driving rod handle 806 is rotated clockwise. The circular driving column 805 on the driving rod 801 is engaged with the driving teeth 804 on the driven magnet rod 803, and the driven magnet rod 803 is moved to the side, so that the driven magnet 802 is separated from the positioning mounting block 202 and gradually separated from the brake magnet 501;

[0068] When the braking magnet 501 is at a sufficient distance from the driven magnet 802, the braking magnet 501 continues to slide toward the inside of the positioning mounting block 202 under the action of the transverse spring 504. At the same time, under the action of the vertical spring 507, the braking magnet braking column 503 moves toward the side away from the driven magnet 802, and the pressing column 502 moves upward, so that the positioning fixing plate 7 can be easily removed from the support column 2. The structure is simple and the efficiency of installation and disassembly is greatly improved.

[0069] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0070] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0071] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
