Description

Technical Field

[0001] This invention belongs to the field of power distribution box technology, and specifically relates to a power distribution box device that is easy to maintain. Background Technology

[0002] As a crucial piece of equipment in the power system, the power distribution box undertakes the key mission of rationally distributing electrical energy. It accurately distributes electrical energy from the upstream power source to various electrical devices or downstream power distribution systems according to different power needs, thereby effectively ensuring the stability and security of power supply and making power use efficient and reliable.

[0003] A search of patent document CN115882358B reveals an IoT power distribution cabinet that facilitates maintenance. The cabinet includes a cabinet body, a cabinet door, an observation window, and a maintenance door. The cabinet door is rotatably mounted on the front of the cabinet body via a pivot, and a transparent observation window is located at the top of the door. The maintenance door is rotatably mounted on the rear of the cabinet body via a pivot. The cabinet also includes a latching mechanism for adjusting the internal structure to facilitate maintenance and a cover-opening mechanism for increasing maintenance space and introducing external light. The latching mechanism allows for the movement of the structural panels, thereby enabling adjustments to the internal structure of the distribution cabinet and facilitating maintenance by personnel.

[0004] While the aforementioned patent documents enable the repositioning of the structural plates, thereby allowing adjustments to the internal structure of the distribution cabinet for easier maintenance, under current technological conditions, the cabinet often integrates numerous electronic components. These components are densely packed and interconnected, making the internal structure of the entire distribution cabinet complex. Traditional maintenance methods are extremely cumbersome, requiring maintenance personnel to inspect each module in the distribution box one by one. This process not only consumes a significant amount of time and effort but is also particularly inefficient in emergency situations. More seriously, if short-circuit faults are not addressed promptly and effectively during maintenance, they could potentially lead to serious safety accidents such as fires. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a power distribution box device that is easy to maintain. This effectively solves the problem that, under existing technological conditions, the cabinet often integrates numerous electronic components, which are densely packed and interconnected, making the internal structure of the entire distribution cabinet complex. Traditional maintenance methods are extremely cumbersome, requiring maintenance personnel to inspect each module in the distribution box one by one. This process not only consumes a significant amount of time and effort but is also particularly inefficient in emergency situations. More seriously, if short-circuit faults are not addressed promptly and effectively during maintenance, it could potentially lead to serious safety accidents such as fires.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power distribution box device that is easy to maintain, comprising a box body and an electronic component body, and a triggering mechanism disposed inside the box body. The triggering mechanism includes a square shell fixedly connected to the inside of the box body, a slider slidably connected inside the square shell, and the square shell and the slider being elastically connected by an elastic element. A connecting block is fixedly installed at the bottom end of the slider, and an insert block is slidably connected inside the connecting block. The insert block and the connecting block are elastically connected by an elastic element. A metal block is fixedly installed on one side of the connecting block, and an electromagnet located at the bottom end of the metal block is fixedly installed on one side of the electronic component body. A pushing assembly is provided inside the box body, which can drive the slider to slide inside the square shell.

[0007] As a further improvement of the present invention, the pushing component includes an airbag fixedly connected to the inside of the housing, and the airbags are arranged in pairs and located at the rear end of the electronic component body. The airbags are connected to the square shell through a connecting tube.

[0008] As a further improvement of the present invention, it also includes:

[0009] A power-off mechanism is provided on the side of the electronic component body away from the airbag. The power-off mechanism includes a mounting plate fixedly connected to the side of the electronic component body away from the airbag. A connecting shell is fixedly installed on one side of the mounting plate. A push plate is slidably connected inside the connecting shell. The push plate and the connecting shell are elastically connected by an elastic element.

[0010] A limiting component is located on one side of the housing and can fix the push plate.

[0011] As a further improvement of the present invention, the limiting component includes a mounting shell fixedly connected to one side of the housing, a limiting block slidably connected inside the mounting shell, and the limiting block and the mounting shell are elastically connected by an elastic element.

[0012] As a further improvement of the present invention, it also includes:

[0013] The abutment mechanism is located inside the housing. The abutment mechanism includes a fixed shell fixedly connected to the inside of the housing, with two fixed shells located on both sides of the electronic component body. A mounting block is slidably connected inside the fixed shell. A pressing wheel is rotatably connected inside the mounting block on the side of the mounting block closest to the electronic component body. The mounting block and the fixed shell are elastically connected by an elastic element. A pressing block is slidably connected inside the fixed shell. An L-shaped plate is fixedly installed on the side of the pressing block away from the surface of the fixed shell, and one end of the L-shaped plate is fixedly connected to the airbag.

[0014] As a further improvement of the present invention, it also includes:

[0015] A heat dissipation assembly is disposed on one side of the housing. The heat dissipation assembly includes a heat dissipation plate fixedly connected to one side of the housing, and heat dissipation holes are provided at the top of the electronic component body.

[0016] As a further improvement of the present invention, an abutment block is fixedly installed inside the connecting block, and the abutment block is a mirror design, with the surface of the abutment block in contact with the surface of the insert block.

[0017] As a further improvement of the present invention, the side opposite to the extrusion block and the mounting block is designed with an inclined surface, and the two inclined surfaces are parallel to each other, and the surface of the extrusion block is designed with a smooth surface.

[0018] As a further improvement of the present invention, the connecting shell is arc-shaped, and the surface of the push plate is in contact with the inner wall of the connecting shell. The surface of the push plate is smooth, and the push plate located inside the connecting shell is cylindrical.

[0019] The present invention also provides a method of using a power distribution box device that is easy to maintain, the method of using the device comprising the following steps;

[0020] S1, by inserting the electronic component body into the housing, during the insertion process, it will contact one end of the airbag and compress the air inside it. The air will enter the square shell and push the slider, connecting block and insert block. The insert block will be inserted into the slot at the top of the electronic component body, and the metal block will contact the electromagnet, driving the electronic component body to work. The electromagnet will attract the metal block and fix the electronic component body inside the housing. The insert block that enters the electronic component body will assist the electromagnet in fixing the electronic component body.

[0021] S2, when one of the electronic components fails and loses power, the corresponding electromagnet's magnetic force will disappear. As the electromagnet's magnetic force disappears, the elastic element will pull the slider, connecting block, and insert block to retract into the square shell. The metal block will move away from the surface of the electromagnet. Then, the air inside the square shell will pass through the connecting tube and enter the airbag again to expand. The expanded airbag will push the electronic component out of the box for easy maintenance.

[0022] S3, when the connecting tube pushes the electronic component body to move, it will move the L-shaped plate and the extrusion block in conjunction. The extrusion block will push the mounting block and the extrusion wheel to move towards the surface of the electronic component body. When the mounting block moves, the elastic element three will be stretched. Then the surface of the extrusion wheel will contact the surface of the electronic component body. At the same time as the contact, the moving electronic component body will drive the extrusion wheel to rotate. As the two rotating extrusion wheels squeeze each other, the electronic component body can move at a uniform speed.

[0023] S4, when the electronic component body is moved out of the housing, the electronic component body will drive the mounting plate and the push plate to move. The push plate will move away from the limiting component, and the limiting component will release the push plate from the fixing. The compressed elastic element will push the push plate to slide along the inner wall of the connecting shell. During the sliding process, the knife switch on one side of the electronic component body will be closed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention provides a power distribution box device that is easy to maintain. When the electronic component body fails and is de-energized, the triggering mechanism pushes the short-circuited electronic component body out of the box under its own elastic force. During the pop-out process, the short-circuited electronic component body is de-energized, which enables the operator to quickly locate the faulty component, greatly shortens the maintenance time, improves the maintenance efficiency, and does not require additional power-off operation. This avoids the risk of electric shock caused by operational errors and effectively prevents fire caused by short circuit faults.

[0026] (2) Through the coordinated action of the triggering mechanism and the pushing component, the present invention can both remove the auxiliary fixation of the electronic component body by using the elastic element to pull the slider, connecting block and insert block into the square shell, and allow the air inside the square shell to enter the airbag and expand to push the electronic component body out of the box. Specifically, after the magnetic force of the electromagnet disappears, the stretched elastic element will pull the slider, connecting block and insert block into the square shell, and the slider will squeeze the air inside the square shell. The air will pass through the connecting tube into the airbag and expand to push out the electronic component body, so that the operator can quickly locate the faulty component, greatly shorten the maintenance time and improve the maintenance efficiency.

[0027] (3) Through the coordinated operation of the power-off mechanism and the limiting component, the present invention can both push the push plate along the inner wall of the connecting shell to close the knife switch on one side of the electronic component body by pushing the elastic element four, and limit the push plate by the limiting component to ensure that the electronic component body without failure can work stably. Specifically, the electronic component body will drive the mounting plate and the push plate, and the push plate will move away from the limiting component. The limiting component will cancel the fixation of the push plate, and the compressed elastic element four will push the push plate to slide along the inner wall of the connecting shell. During the sliding process, the power supply of the electronic component body can be quickly cut off, so that the operator does not need to perform additional power-off operation, which avoids the risk of electric shock caused by operation error and effectively prevents fire caused by short circuit fault.

[0028] (4) The present invention, through the cooperation of the mounting block, the elastic element, the extrusion wheel and the extrusion block, can not only push the extrusion wheel to contact the electronic component body through the extrusion block, but also use the movement of the electronic component body to drive the rotation of the extrusion wheel, so as to ensure that the electronic component body can move at a uniform speed. Specifically, the inflated airbag will move the L-shaped plate and the extrusion block together, and the extrusion block will push the mounting block and the extrusion wheel to move towards the surface of the electronic component body. The surface of the extrusion wheel will contact the surface of the electronic component body. At the same time as the contact, the moving electronic component body will drive the extrusion wheel to rotate. As the two rotating extrusion wheels squeeze each other, the electronic component body can move at a uniform speed, which improves the stability of the movement of the electronic component body and provides great convenience for subsequent maintenance operations, further improving the reliability and practicality of the entire equipment.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" indicate orientation or positional relationships only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0043] It should be understood that, in the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms “installation,” “connection,” and “linking” should be interpreted broadly.

[0044] Example 1: See Appendix Figures 1 to 11This embodiment 1 provides a power distribution box device that is easy to maintain, including a box body 100 and an electronic component body 200, and also includes a triggering mechanism 300, which is disposed inside the box body 100. The triggering mechanism 300 includes a square shell 301 fixedly connected inside the box body 100. A slider 302 is slidably connected inside the square shell 301. The square shell 301 and the slider 302 are elastically connected by an elastic element 303. A connecting block 304 is fixedly installed at the bottom end of the slider 302. An insert block 305 is slidably connected inside the connecting block 304. The insert block 305 and the connecting block 304 are elastically connected by an elastic element 306. A metal block 307 is fixedly installed on one side of the connecting block 304. An electromagnet 308 located at the bottom end of the metal block 307 is fixedly installed on one side of the electronic component body 200. A pushing assembly 400 is disposed inside the box body 100 and can drive the slider 302 to slide inside the square shell 301.

[0045] It is not difficult to understand that: when the operator inserts the electronic component body 200 into the housing 100, it will come into contact with one end of the pushing component 400 during the insertion process, and will compress the air inside it. The air will enter the square shell 301 and push the slider 302, the connecting block 304 and the insertion block 305 to move. When the slider 302 moves, the elastic element 303 will be stretched. Using the restorative property of the elastic element 303, the slider 302 can be reset. Then the insertion block 305 will enter the interior of the electronic component body 200, and the metal block 307 will come into contact with the electromagnet 308. The electromagnet 308 and the electronic component body 200 share the same power supply, which can drive the electronic component body 200 to work. While working, the electromagnet 308 will attract the metal block 307 and fix the electronic component body 200 inside the housing 100. The insertion block 305 entering the interior of the electronic component body 200 will assist the electromagnet 308 in fixing the electronic component body 200.

[0046] During the operation of the equipment, if one of the electronic components 200 malfunctions and loses power, the magnetism of the electromagnet 308 will disappear. As the magnetism of the electromagnet 308 disappears, the stretched elastic element 303 will pull the slider 302, connecting block 304, and insert block 305 to retract into the square shell 301. The metal block 307 will move away from the surface of the electromagnet 308. Then, the air inside the square shell 301 will re-enter the pushing assembly 400. As the air enters, the pushing assembly 400 will expand and push the electronic component 200 out of the housing 100. During the movement of the electronic component 200, the insert block 305 cannot immediately move away from the interior of the electronic component 200. It will slide inside the connecting block 304. When it moves, the elastic element 2 306 will be stretched, so the insert block 305 will not jam the movement of the electronic component body 200. Then the insert block 305 will move away from the inside of the electronic component body 200. When it moves away from the inside of the electronic component body 200, the stretched elastic element 2 306 will pull the insert block 305 to reset. After the electronic component body 200 is pushed out, the operator can quickly locate the faulty component, which greatly shortens the maintenance time and improves the maintenance efficiency. There are seven electronic component bodies 200, and a trigger mechanism 300 and a push component 400 are respectively set at the top and rear of the seven electronic component bodies 200 to facilitate the movement of the electronic component bodies 200.

[0047] It should be noted that there are two enclosures 100. The control cabinet is located inside the left enclosure 100, while the electronic component body 200 is located inside the right enclosure 100. These are all existing mature technologies and will not be described in detail.

[0048] like Figure 6 and Figure 9 As shown, the pushing component 400 includes airbags 401 fixedly connected inside the housing 100, and the airbags 401 are located at the rear end of the electronic component body 200 in pairs. The airbags 401 are connected to the square shell 301 through the connecting tube 402.

[0049] It is not difficult to understand that by pushing the component 400, when the elastic element 303 pulls the slider 302 to retract into the square shell 301, the air inside the square shell 301 will pass through the connecting pipe 402 and enter the air bag 401 because the air bag 401 is connected to the square shell 301 through the connecting pipe 402. As the air is injected, the air bag 401 will expand, and the expanded air bag 401 will push the faulty electronic component body 200 away from the inside of the housing 100.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, it also includes:

[0051] The power-off mechanism 600 is disposed on the side of the electronic component body 200 away from the airbag 401. The power-off mechanism 600 includes a mounting plate 601 fixedly connected to the side of the electronic component body 200 away from the airbag 401. A connecting shell 602 is fixedly installed on one side of the mounting plate 601. A push plate 603 is slidably connected inside the connecting shell 602. The push plate 603 and the connecting shell 602 are elastically connected by an elastic member 604.

[0052] The limiting component 700 is located on one side of the housing 100 and can fix the push plate 603.

[0053] It is easy to understand that, through the design of the power-off mechanism 600, when the electronic component body 200 is moved out of the housing 100, the electronic component body 200 will drive the mounting plate 601 and connecting pipe 402 to move, and the push plate 603 will move away from the limiting component 700. The limiting component 700 will then release the fixing of the push plate 603, and the compressed elastic element 604 will push the push plate 603 to slide along the inner wall of the connecting shell 602. During the sliding process, the knife switch on one side of the electronic component body 200 will be closed, so that the entire electronic component body 200 is de-energized. With the limit of the knife switch, the push plate 603 will not cross the knife switch. In this way, during maintenance, the operator does not need to perform additional power-off operations, which avoids the risk of electric shock due to operational errors and effectively prevents fire caused by short circuit faults. It provides comprehensive protection for the safe operation of the power distribution system and does not interfere with the operation of other electronic component bodies 200.

[0054] like Figure 5 As shown, the limiting component 700 includes a mounting shell 701 fixedly connected to one side of the housing 100, a limiting block 702 slidably connected inside the mounting shell 701, and the limiting block 702 and the mounting shell 701 are elastically connected by an elastic element 703.

[0055] It is not difficult to understand that, through the design of the limiting component 700, after the electronic component body 200 is repaired, it can be reinserted into the housing 100, and the knife switch can be pushed to energize it. When the knife switch is turned, it will push the push plate 603 to slide inside the connecting shell 602 and squeeze the push plate 603. Then the push plate 603 will come into contact with the surface of the limiting block 702. Since the part of the limiting block 702 that contacts the push plate 603 is chamfered, it will squeeze the limiting block 702 to retract into the mounting shell 701, and the elastic element 703 will be compressed. Then the push plate 603 will pass over the limiting block 702. During the process of passing over, the compressed limiting block 702 will push the limiting block 702 to reset. Utilizing the restorative property of the elastic element 604, the limiting block 702 can limit the push plate 603.

[0056] like Figure 6 , Figure 7 and Figure 8 As shown, it also includes:

[0057] The abutment mechanism 500 is disposed inside the housing 100. The abutment mechanism 500 includes a fixed housing 501 fixedly connected inside the housing 100. The fixed housings 501 are arranged in pairs and located on both sides of the electronic component body 200. The mounting block 502 is slidably connected inside the fixed housing 501. The pressing wheel 504 is rotatably connected inside the mounting block 502 on the side of the mounting block 502 closest to the electronic component body 200. The mounting block 502 and the fixed housing 501 are elastically connected by an elastic member 503. The pressing block 506 is slidably connected inside the fixed housing 501. An L-shaped plate 505 is fixedly installed on the side of the pressing block 506 away from the surface of the fixed housing 501. One end of the L-shaped plate 505 is fixedly connected to the airbag 401.

[0058] It should be noted that, through the design of the abutment mechanism 500, when the connecting tube 402 pushes the electronic component body 200 to move, it will move the L-shaped plate 505 in conjunction. The L-shaped plate 505 will drive the pressing block 506 to move inside the fixed shell 501. The moving pressing block 506 will contact the surface of the mounting block 502 and will squeeze and push the mounting block 502. When the mounting block 502 moves, the elastic element 3 503 will be stretched. Then the mounting block 502 will drive the pressing wheel 504 to move towards the surface of the electronic component body 200. The surface of the pressing wheel 504 will contact the surface of the electronic component body 200. At the same time as the contact, the moving electronic component body 200 will drive the pressing wheel 504 to rotate. As the two rotating pressing wheels 504 squeeze each other, the electronic component body 200 can move at a uniform speed.

[0059] like Figure 6 As shown, it also includes:

[0060] A heat dissipation assembly 800 is disposed on one side of the housing 100. The heat dissipation assembly 800 includes a heat dissipation plate 801 fixedly connected to one side of the housing 100, and a heat dissipation hole 802 is provided at the top of the electronic component body 200.

[0061] It should be noted that, through the design of the heat dissipation component 800, during the operation of the electronic component body 200, external air will pass through the heat dissipation plate 801 and heat dissipation holes 802 to enter the interior of the electronic component body 200, thereby dissipating heat from the electronic components inside the electronic component body 200.

[0062] like Figure 10 As shown, a contact block 900 is fixedly installed inside the connecting block 304, and the contact block 900 is a mirror design, with the surface of the contact block 900 in contact with the surface of the insert block 305.

[0063] It should be noted that, through the design of the abutment block 900, when the electronic component body 200 is inserted into the housing 100, the electronic component body 200 will be able to smoothly squeeze the insertion block 305 into the square shell 301 by using the limiting of the abutment block 900, so that the insertion block 305 can easily enter the interior of the electronic component body 200.

[0064] like Figure 11 As shown, the extrusion block 506 and the mounting block 502 are both designed with bevels on the opposite side, and the two bevels are parallel to each other. The surface of the extrusion block 506 is designed to be smooth.

[0065] It should be noted that, through the design of the extrusion block 506 and the mounting block 502, since both the extrusion block 506 and the mounting block 502 have an inclined design on the opposite side, the extrusion block 506 can easily push the mounting block 502. Furthermore, the surface of the extrusion block 506 is designed to be smooth, which can reduce the resistance to movement and ensure that the extrusion block 506 can smoothly push the mounting block 502 to move.

[0066] like Figure 4 and Figure 5 As shown, the connecting shell 602 has an arc-shaped design, and the surface of the push plate 603 is in contact with the inner wall of the connecting shell 602. The surface of the push plate 603 has a smooth design, and the push plate 603 located inside the connecting shell 602 has a cylindrical design.

[0067] It should be noted that, through the design of the connecting shell 602 and the push plate 603, since the connecting shell 602 is arc-shaped, the push plate 603 will slide along the inner wall of the connecting shell 602, thereby driving the knife switch to rotate. Furthermore, the surface of the push plate 603 is smooth, which allows the push plate 603 to move more smoothly.

[0068] The present invention also provides a method of using a power distribution box device that is easy to maintain, the method of using the device comprising the following steps;

[0069] S1, by inserting the electronic component body 200 into the housing 100, during the insertion process, it will contact one end of the airbag 401 and compress the air inside it. The air will enter the square shell 301 and push the slider 302, the connecting block 304 and the insertion block 305. The insertion block 305 will be inserted into the slot at the top of the electronic component body 200, and the metal block 307 will contact the electromagnet 308, driving the electronic component body 200 to work. The electromagnet 308 will attract the metal block 307 and fix the electronic component body 200 inside the housing 100. The insertion block 305 entering the electronic component body 200 will assist the electromagnet 308 in fixing the electronic component body 200.

[0070] S2, when one of the electronic components 200 fails and loses power, the magnetic force of the corresponding electromagnet 308 will disappear. As the magnetic force of the electromagnet 308 disappears, the elastic element 303 will pull the slider 302, the connecting block 304 and the insert block 305 to retract into the square shell 301. The metal block 307 will move away from the surface of the electromagnet 308. Then the air inside the square shell 301 will pass through the connecting tube 402 and enter the air bag 401 to expand. The expanded air bag 401 will push the electronic component 200 out of the box 100 for easy maintenance.

[0071] S3, when the connecting pipe 402 pushes the electronic component body 200 to move, it will move the L-shaped plate 505 and the extrusion block 506 in conjunction. The extrusion block 506 will push the mounting block 502 and the extrusion wheel 504 to move toward the surface of the electronic component body 200. When the mounting block 502 moves, the elastic element 3 503 will be stretched. Then the surface of the extrusion wheel 504 will contact the surface of the electronic component body 200. At the same time as the contact, the moving electronic component body 200 will drive the extrusion wheel 504 to rotate. As the two rotating extrusion wheels 504 squeeze each other, the electronic component body 200 can move at a uniform speed.

[0072] S4, when the electronic component body 200 moves out of the housing 100, the electronic component body 200 will drive the mounting plate 601 and the push plate 603 to move, and the push plate 603 will move away from the limiting component 700. The limiting component 700 will release the fixation of the push plate 603, and the compressed elastic element 604 will push the push plate 603 to slide along the inner wall of the connecting shell 602. During the sliding process, the knife switch on one side of the electronic component body 200 will be closed.

[0073] It is not difficult to understand that after the electronic component body 200 is repaired, it can be reinserted into the housing 100, and the knife switch can be pushed to energize it. When the knife switch is turned, it will push the push plate 603 to slide inside the connecting shell 602 and squeeze the push plate 603. The push plate 603 will push the limit block 702 to retract into the mounting shell 701. The push plate 603 will pass over the limit block 702. During the process of passing over, the compressed limit block 702 will push the limit block 702 to reset. By utilizing the restorative property of the elastic element 604, the limit block 702 can limit the push plate 603.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
