Technical Field
[0001] This invention relates to the field of DC power supply technology, specifically to a DC power supply that facilitates the installation and removal of batteries. Background Technology
[0002] The DC power supply panel, commonly known as an intelligent maintenance-free DC power supply panel, is the foundation of modern power system control and protection. It consists of AC distribution unit, charging module unit, step-down silicon chain unit, DC feeder unit, power distribution monitoring unit, monitoring module unit, and insulation monitoring unit.
[0003] The DC power supply provides DC power when the AC power is interrupted. The DC power is provided by the battery. The existing battery is quite heavy, and it is inconvenient to install and remove the battery during maintenance and replacement, which is not conducive to maintenance and replacement.
[0004] Therefore, a DC power supply that facilitates battery installation and removal is proposed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a DC power supply panel that facilitates the installation and removal of batteries, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A DC power supply panel for easy battery installation and removal includes a DC power supply panel housing, a DC power supply panel control unit, and a battery. The control unit is located on the left side of the inner wall of the DC power supply panel housing. Battery support plates are evenly distributed on the rear side wall of the DC power supply panel housing. A latching structure for battery positioning is connected to the top of each battery support plate, and the battery is latched within the latching structure. A height adjustment structure is located on the outer side of the battery on the rear side wall of the DC power supply panel housing, and this height adjustment structure includes an installation and removal mechanism. A limiting structure is located at the bottom of each battery support plate, allowing the latching structure to be opened. This limiting structure is connected to the installation and removal mechanism and the height adjustment structure. A side plate is rotatably mounted on the right side wall of the DC power supply panel housing via a latch and hinge.
[0008] Furthermore, the snap-fit structure includes a U-shaped limiting plate, a U-shaped connecting plate, a triangular limiting plate, a spring, a guide roller, a horizontal guide rail, a straight plate, and an inclined pressure plate. The U-shaped limiting plate is symmetrically installed on the top of the battery support plate. The guide roller rotates evenly on the front and rear inner walls of the U-shaped limiting plate through bearings. The bottom of the battery support plate is symmetrically fixed with springs. The bottom of the springs is fixed with U-shaped connecting plates. The top of the U-shaped connecting plate passes through the springs and the horizontal guide rail and is fixedly connected with a triangular limiting plate. The upright part of the triangular limiting plate, the top of the guide roller, and the inner wall of the U-shaped limiting plate are all in close contact with the outer wall of the battery. The bottom of the inner wall of the U-shaped connecting plate is in close contact with an inclined pressure plate. The bottom of the inclined pressure plate is connected with a straight plate.
[0009] Furthermore, the inclined surface of the triangular limiting plate is set towards the side plate, and the upright part of the triangular limiting plate is set towards the upward U-shaped limiting plate.
[0010] Furthermore, when the U-shaped connecting plate contacts the upper end of the inclined pressure plate, the triangular limiting plate moves to the uppermost position; when the U-shaped connecting plate contacts the lower end of the inclined pressure plate, the triangular limiting plate moves to the lowermost position; and when the triangular limiting plate moves to the lowermost position, the top of the triangular limiting plate is lower than the top of the guide roller.
[0011] Furthermore, the height adjustment structure includes a drive wheel, a drive belt, and a drive motor. The drive wheel rotates on the inner rear wall of the DC power supply enclosure via a bearing, and the drive belt rotates on the outer wall of the drive wheel. The drive motor is mounted on the outer wall of the DC power supply enclosure, and the output end of the drive motor is coaxially connected to a set of the drive wheels.
[0012] Furthermore, the drive wheel can be a synchronous wheel or a gear.
[0013] Furthermore, the loading and unloading structure includes a sliding support plate, a movable seat, a horizontal support seat, a first connecting seat, a second connecting seat, and a horizontal shaft. The rear end of the movable seat is fixedly connected to the outer wall of the drive belt. The upper end of the movable seat away from the battery support plate side wall is fixedly provided with a second connecting seat at equal intervals. The second connecting seat is fixedly connected to the horizontal shaft. The first connecting seat is rotatably connected to the horizontal shaft through a bearing. The top of the first connecting seat is fixedly provided with a sliding support plate. The lower end of the movable seat away from the battery support plate side wall is provided with a horizontal support seat. When the side wall of the sliding support plate is in contact with the top of the horizontal support seat, the top of the sliding support plate is flush with the top of the movable seat. At the same time, the top of the sliding support plate is flush with the top of the adjacent guide roller.
[0014] Furthermore, the limiting structure includes a linear drive assembly, a linear guide rail, a socket, a horizontal guide rail, a limiting insert plate, and a limiting slider. The linear drive assembly and the horizontal guide rail are installed at the bottom of the battery support plate. The telescopic end of the linear drive assembly is fixed with a limiting insert plate, and the top of the limiting insert plate slides with the horizontal guide rail via a limiting groove. The rear end of the movable seat is fixedly connected to the front end of the limiting slider. The movable seat has a socket near the side wall of the battery support plate for insertion with the limiting insert plate. When the limiting insert plate is inserted into the socket, the movable seat is flush with the top of the guide roller. The linear guide rail is installed on the rear inner wall of the DC screen housing, and the rear end of the limiting slider slides with the linear guide rail via a limiting groove.
[0015] Furthermore, the top of the straight plate is fixedly connected to the bottom of the limiting insert plate.
[0016] Furthermore, a straightening plate is fixed to the lower end of the inner wall of the side plate. When the sliding support plate and the straightening plate come into contact, the straightening plate pushes the sliding support plate to a vertical position.
[0017] The beneficial effects of this invention are:
[0018] 1. In this invention, the battery moves into the U-shaped limiting plate of the snap-fit structure. The battery pushes the triangular limiting plate downward. The battery moves to the top of the guide roller inside the U-shaped limiting plate. The spring drives the horizontal guide rail downward. The horizontal guide rail drives the triangular limiting plate upward. The triangular limiting plate and the U-shaped limiting plate automatically limit the battery, which facilitates the snap-fitting of the battery, ensures the stability of the battery, and facilitates stable power supply from the battery.
[0019] 2. The drive motor of the height adjustment structure of the present invention drives the drive wheel to rotate, the drive wheel drives the drive belt to rotate, and the drive belt moves the loading and unloading structure to the battery, so as to facilitate adjustment to the specific position of the loading and unloading structure in the DC power supply box.
[0020] 3. In this invention, the side plate is opened. After the side plate is opened, the sliding support plate of the mounting and disassembling structure rotates along the horizontal axis by its own gravity, and the sliding support plate rotates to fit and contact the horizontal support seat, which makes it convenient to adjust the sliding support plate to a horizontal state and to facilitate the sliding support plate to support the battery.
[0021] 4. After the side plate of the present invention is closed, the side plate drives the straightening plate to contact the sliding support plate. When the sliding support plate and the straightening plate are in contact, the straightening plate pushes the sliding support plate to a vertical position, which is conducive to the folding and storage of the loading and unloading structure and reduces the space occupied by the loading and unloading structure.
[0022] 5. The linear drive component of the limiting structure of this invention drives the limiting insert plate to move along the horizontal guide rail. The limiting insert plate is inserted into the insertion hole. The limiting insert plate and the insertion hole cooperate to vertically limit the movable seat. The straight guide rail and the limiting slider limit the movable seat horizontally. When the battery moves to the sliding support plate, the stability of the sliding support plate is ensured. When the sliding support plate moves in the vertical direction, the straight guide rail and the limiting slider cooperate to horizontally limit the sliding support plate, preventing the sliding support plate from sliding horizontally. When the limiting insert plate moves, the limiting insert plate drives the straight plate of the snap-fit structure to move. The straight plate drives the inclined pressure plate to move. The inclined pressure plate drives the U-shaped connecting plate to move downward. The U-shaped connecting plate drives the triangular limiting plate to move downward. The triangular limiting plate moves to the lower end of the top of the guide roller, which facilitates the automatic opening of the snap-fit structure without manual operation.
[0023] 6. The battery of this invention is easy to install and remove during maintenance and replacement, which facilitates maintenance and replacement without the need for external equipment. Attached Figure Description

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.
[0040] The present invention will be further described below with reference to embodiments. Example 1
[0041] like Figure 1-12 As shown, a DC power supply panel for easy battery installation and removal includes a DC power supply panel housing 1, a DC power supply panel control unit 2, and a battery 3. The DC power supply panel control unit 2 is located on the left side of the inner wall of the DC power supply panel housing 1. Battery support plates 4 are evenly distributed on the rear side wall of the DC power supply panel housing 1. A snap-fit structure for securing the battery 3 is connected to the top of the battery support plate 4. The battery 3 is snapped into the snap-fit structure. A height adjustment structure is provided on the rear side wall of the DC power supply panel housing 1, and the height adjustment structure is located outside the battery 3. The height adjustment structure has an installation and removal structure. A limiting structure is provided at the bottom of the battery support plate 4. The limiting structure can open the snap-fit structure. The limiting structure is connected to the installation and removal structure and the height adjustment structure. A side plate 7 is rotatably mounted on the right side wall of the DC power supply panel housing 1 via a latch and a hinge.
[0042] Battery 3 is easy to install and remove during maintenance and replacement, which facilitates maintenance and replacement without the need for external equipment. Example 2
[0043] Based on Example 1, see Figure 1 , 2As shown in Figures 4, 6, 8, 9, 11, and 12, the snap-fit structure includes a U-shaped limiting plate 5, a U-shaped connecting plate 10, a triangular limiting plate 13, a spring 14, a guide roller 20, a horizontal guide rail 21, a straight plate 22, and an inclined pressure plate 23. The U-shaped limiting plate 5 is symmetrically installed on the top of the battery support plate 4. The guide roller 20 rotates evenly on the front and rear inner walls of the U-shaped limiting plate 5 through bearings. The bottom of the battery support plate 4 is symmetrically fixed with springs 14. The bottom of the springs 14 is fixed with U-shaped connecting plates 10. The top of the U-shaped connecting plate 10 passes through the springs 14 and the horizontal guide rail 21 and is then fixedly connected with the triangular limiting plate 13. The upright part of the triangular limiting plate 13... The top of the guide roller 20 and the inner wall of the U-shaped limiting plate 5 are in close contact with the outer wall of the battery 3. The bottom of the U-shaped connecting plate 10 is in close contact with the inclined pressure plate 23. The bottom of the inclined pressure plate 23 is connected to the straight plate 22. The inclined surface of the triangular limiting plate 13 is set with the side plate 7 facing upwards. The upright part of the triangular limiting plate 13 is set with the U-shaped limiting plate 5. When the U-shaped connecting plate 10 contacts the upper end of the inclined pressure plate 23, the triangular limiting plate 13 moves to the uppermost end. When the U-shaped connecting plate 10 contacts the lower end of the inclined pressure plate 23, the triangular limiting plate 13 moves to the lowermost end. When the triangular limiting plate 13 moves to the lowermost end, the top of the triangular limiting plate 13 is lower than the top of the guide roller 20.
[0044] The battery 3 moves into the U-shaped limiting plate 5 of the snap-fit structure. The battery 3 pushes the triangular limiting plate 13 to move downward. The battery 3 moves to the top of the guide roller 20 inside the U-shaped limiting plate 5. The spring 14 drives the horizontal guide rail 21 to move downward. The horizontal guide rail 21 drives the triangular limiting plate 13 to move upward. The triangular limiting plate 13 and the U-shaped limiting plate 5 automatically limit the battery 3, which facilitates the snap-fit of the battery 3, ensures the stability of the battery 3, and helps the battery 3 to provide stable power supply. Example 3
[0045] Based on Example 2, see Figure 2 , 3 As shown in Figures 5 and 7, the height adjustment structure includes a drive wheel 8, a drive belt 9, and a drive motor 12. The drive wheel 8 rotates on the inner rear wall of the DC screen housing 1 via a bearing, and the drive belt 9 rotates on the outer wall of the drive wheel 8. The drive motor 12 is mounted on the outer wall of the DC screen housing 1, and the output end of the drive motor 12 is coaxially connected to a set of drive wheels 8. The drive wheels are selected as synchronous pulleys or gears.
[0046] The drive motor 12 of the height adjustment structure drives the drive wheel 8 to rotate, the drive wheel 8 drives the drive belt 9 to rotate, and the drive belt 9 moves the loading and unloading structure to the battery 3, so as to facilitate adjustment to the specific position of the loading and unloading structure inside the DC panel box 1. Example 4
[0047] Based on Example 3, see Figure 1 , 6As shown in Figures 7, 10, 11, and 12, the loading and unloading structure includes a sliding support plate 6, a movable seat 18, a horizontal support seat 19, a first connecting seat 25, a second connecting seat 26, and a horizontal shaft 27. The rear end of the movable seat 18 is fixedly connected to the outer wall of the drive belt 9. The second connecting seat 26 is fixed at equal intervals on the upper end of the side wall of the movable seat 18 away from the battery support plate 4. The horizontal shaft 27 is fixedly connected to the second connecting seat 26. The first connecting seat 25 is rotatably connected to the horizontal shaft 27 through a bearing. The sliding support plate 6 is fixedly fixed to the top of the first connecting seat 25. The horizontal support seat 19 is located at the lower end of the side wall of the movable seat 18 away from the battery support plate 4. When the side wall of the sliding support plate 6 is in contact with the top of the horizontal support seat 19, the top of the sliding support plate 6 is flush with the top of the movable seat 18. At the same time, the top of the sliding support plate 6 is flush with the top of the adjacent guide roller 20.
[0048] When the side plate 7 is opened, the sliding support plate 6 of the detachable structure rotates along the horizontal axis 27 under its own weight, and the sliding support plate 6 rotates to fit and contact the horizontal support seat 19, so that the sliding support plate 6 can be adjusted to a horizontal state and the sliding support plate 6 can support the battery 3. Example 5
[0049] Based on Example 4, see Figure 4 , 7 9 and 12, the limiting structure includes a linear drive assembly 15, a straight guide rail 16, a socket 17, a horizontal guide rail 21, a limiting insert plate 24, and a limiting slider 28. The linear drive assembly 15 and the horizontal guide rail 21 are installed at the bottom of the battery support plate 4. The telescopic end of the linear drive assembly 15 is fixed with the limiting insert plate 24, and the top of the limiting insert plate 24 slides with the horizontal guide rail 21 through a limiting groove. The rear end of the movable seat 18 is fixedly connected to the front end of the limiting slider 28. The movable seat 18 has a socket 17 near the side wall of the battery support plate 4 for insertion with the limiting insert plate 24. When the limiting insert plate 24 is inserted with the socket 17, the movable seat 18 is flush with the top of the guide roller 20. The straight guide rail 16 is installed on the rear inner wall of the DC screen box 1. The rear end of the limiting slider 28 is slidably connected to the straight guide rail 16 through a limiting groove. The top of the straight plate 22 is fixedly connected to the bottom of the limiting insert plate 24.
[0050] The linear drive assembly 15 of the limiting structure drives the limiting insert 24 to move along the horizontal guide rail 21. The limiting insert 24 is inserted into the insertion hole 17. The limiting insert 24 and the insertion hole 17 cooperate to vertically limit the movable seat 18. The straight guide rail 16 and the limiting slider 28 horizontally limit the movable seat 18. When the battery 3 moves onto the sliding support plate 6, it ensures the stability of the sliding support plate 6. When the sliding support plate 6 moves vertically, the straight guide rail 16 and the limiting slider 28 cooperate to horizontally limit the sliding support plate 6, preventing the sliding support plate 6 from sliding horizontally. When the limiting insert 24 moves, the limiting insert 24 drives the straight plate 22 of the snap-fit structure to move. The straight plate 22 drives the inclined pressure plate 23 to move. The inclined pressure plate 23 drives the U-shaped connecting plate 10 to move downward. The U-shaped connecting plate 10 drives the triangular limiting plate 13 to move downward. The triangular limiting plate 13 moves to the lower end of the top of the guide roller 20, which facilitates the automatic opening of the snap-fit structure without manual operation. Example 6
[0051] Based on Example 5, see Figure 2 and 6 As shown, a straightening plate 11 is fixed to the lower end of the inner wall of the side plate 7. When the sliding support plate 6 and the straightening plate 11 come into contact, the straightening plate 11 pushes the sliding support plate 6 to a vertical position.
[0052] After the side plate 7 is closed, the side plate 7 causes the straightening plate 11 to contact the sliding support plate 6. When the sliding support plate 6 and the straightening plate 11 are in contact, the straightening plate 11 pushes the sliding support plate 6 to a vertical position, which facilitates the folding and storage of the loading and unloading structure and reduces the space occupied by the loading and unloading structure.
[0053] In actual use: When side panel 7 is opened, the sliding support plate 6 of the mounting and detaching structure rotates along the horizontal axis 27 under its own weight, and the sliding support plate 6 rotates until it is in contact with the horizontal support seat 19, making it easy to adjust the sliding support plate 6 to a horizontal state and to support the battery 3. Then, the drive motor 12 of the height adjustment structure drives the drive wheel 8 to rotate, which in turn drives the drive belt 9 to rotate. The drive belt 9 moves the mounting and detaching structure to the battery 3, facilitating adjustment to the specific position of the sliding support plate 6 within the DC power supply enclosure 1. The corresponding linear drive assembly 15 of the limiting structure drives the limiting insert 24 to move along the horizontal guide rail 21, inserting the limiting insert 24 into the socket 17. The limiting insert 24 and the socket 1... 7. The movable seat 18 is vertically limited, and the straight guide rail 16 and the limiting slider 28 are horizontally limited. When the battery 3 moves onto the sliding support plate 6, the stability of the sliding support plate 6 is ensured. At the same time, the limiting insert plate 24 drives the straight plate 22 of the snap-fit structure to move. The straight plate 22 drives the inclined pressure plate 23 to move. The inclined pressure plate 23 drives the U-shaped connecting plate 10 to move downward. The U-shaped connecting plate 10 drives the triangular limiting plate 13 to move downward. The triangular limiting plate 13 moves to the lower end of the top of the guide roller 20, which facilitates the automatic opening of the snap-fit structure without manual operation. Then, the battery 3 in the U-shaped limiting plate 5 is pushed onto the sliding support plate 6. Then, the linear drive assembly 15 drives the limiting insert plate 24 to separate from the insertion hole 17. The drive motor 12 of the height adjustment structure... The drive wheel 8 rotates, which in turn drives the drive belt 9 to rotate. The drive belt 9 moves the loading and unloading structure to its lowest position, allowing the battery 3 to be inspected and replaced. After the battery 3 is inspected and replaced, the drive motor 12 of the height adjustment structure drives the drive wheel 8 to rotate, which in turn drives the drive belt 9 to rotate. The drive belt 9 moves the loading and unloading structure, which moves the battery 3 to the corresponding U-shaped limiting plate 5. This pushes the battery 3 into the U-shaped limiting plate 5 of the locking structure. The battery 3 pushes the triangular limiting plate 13 downwards. The battery 3 moves to the top of the guide roller 20 inside the U-shaped limiting plate 5. The spring 14 drives the horizontal guide rail 21 downwards, which in turn drives the triangular limiting plate 13 upwards. The triangular limiting plate 13 and the U-shaped limiting plate 5 then engage the battery. The battery 3 is automatically limited, which facilitates the positioning of the battery 3, ensures the stability of the battery 3, and facilitates stable power supply from the battery 3. The battery 3 is easy to install and remove during maintenance and replacement without the need for external equipment. Finally, the drive motor 12 of the height adjustment structure drives the drive wheel 8 to rotate, the drive wheel 8 drives the drive belt 9 to rotate, and the drive belt 9 moves the loading and unloading structure. The loading and unloading structure moves the battery 3 to the lowest position, and then closes the side plate 7. After the side plate 7 is closed, the side plate 7 drives the straightening plate 11 to contact the sliding support plate 6. When the sliding support plate 6 and the straightening plate 11 are in contact, the straightening plate 11 pushes the sliding support plate 6 to a vertical position, which facilitates the folding and storage of the loading and unloading structure and reduces the space occupied by the loading and unloading structure.
[0054] When the sliding support plate 6 moves in the vertical direction, the straight guide rail 16 and the limiting slider 28 cooperate to limit the sliding support plate 6 horizontally, so as to prevent the sliding support plate 6 from sliding horizontally.
