Abstract
Description
Technical Field
[0001] This application relates to the field of inverter technology, specifically to a movable grid-connected inverter motherboard structure and its movable method. Background Technology
[0002] A grid-connected inverter is a power device that converts direct current (DC) to alternating current (AC) and synchronizes its output AC with the frequency and phase of the mains power grid. The AC output from the inverter can then be directly fed back into the grid, achieving grid connection of electrical energy. In renewable energy power generation systems, such as photovoltaic and wind power generation, the grid-connected inverter is a key component connecting the power generation equipment and the grid. Since the grid-connected inverter relies entirely on the grid for operation, the system will not function properly when the grid is interrupted or malfunctions. Therefore, the stability and reliability of the grid must be considered when designing and installing a grid-connected system. The inverter motherboard is one of the core components of the inverter. It integrates the inverter's control and power circuits, is responsible for converting DC to AC, and uses control logic to achieve stable operation and protection functions for the inverter.
[0003] Currently, since the inverter motherboard is a core component, it requires regular maintenance. However, the existing inverter motherboard is fixed during installation, and all its fixing structures, such as screws, need to be completely removed before it can be disassembled. This is not only quite troublesome, but may also result in the loss of screws and other small fixing parts during the disassembly process, leading to low maintenance efficiency. Summary of the Invention
[0004] The purpose of this application is to provide a movable grid-connected inverter motherboard structure and its moving method, which solves the problem mentioned in the background art that the existing inverter motherboard is fixed during installation and requires the complete removal of all its fixing structures such as screws to be disassembled. This is not only cumbersome, but may also lead to the loss of screws and other small fixing parts during disassembly, resulting in low maintenance efficiency.
[0005] To achieve the above objectives, this application provides the following technical solution: a movable grid-connected inverter motherboard structure, comprising a housing, a sliding frame, a movable frame, a support frame, and a connecting rod. The housing has outer sliding grooves on its front and rear inner walls. The front and rear sides of the sliding frame are laterally connected within the outer sliding grooves, and the sliding frame also has inner sliding grooves on its front and rear inner walls. Two first-order sliders are slidably connected within the inner sliding grooves. The two ends of the support frame are fixedly connected to the first-order sliders on both sides. Two second-order sliders are slidably connected to the surface of the support frame. A limit block is fixedly connected to the top of each second-order slider. A movable frame is hinged to the left side of the top of the sliding frame. Two first-order socket blocks are movably sleeved on the surfaces of the straight rods on the front and rear sides of the movable frame. The two ends of the connecting rod are fixedly connected to the first-order socket blocks on both sides, and two second-order socket blocks are movably sleeved on the surface of the connecting rod. A rubber pad is fixedly connected to the bottom of each second-order socket block.
[0006] In this technical solution, the position of slider number one in the inner slide groove is adjusted to fit the length of the motherboard. Then, the position of slider number two on the support frame is adjusted so that the limiting block at the top of slider number two corresponds to the four corners of the motherboard. The four corners of the motherboard are placed in the limiting blocks. Then, the position of socket number one on the movable frame is adjusted so that it corresponds to the position of the support frame below. Then, the position of socket number two on the sliding connecting block is adjusted so that it corresponds to the limiting block below. After the movable frame is pressed down, the rubber pad at the bottom of socket number two will press down on the four corners of the motherboard, thus completing the installation and ensuring the stability of the motherboard. It can be freely adjusted according to the size of the motherboard, adapting to the fixing of different motherboards and improving adaptability and practicality. The front and rear sides of the sliding frame are pushed into the outer slide groove along the outer slide groove. When disassembly is required, the sliding frame can be pulled out, thus eliminating the need to disassemble the entire inverter, improving the practicality and maintenance efficiency of the device.
[0007] As an optional solution to the technical solution of this application, a baffle is fixedly connected to the right side surface of the sliding frame, and two fixing plates are fixedly connected to the upper edge of the right side wall of the baffle.
[0008] As an optional solution to the technical solution of this application, the top end of the first slider is threadedly connected to a first fixing bolt, and the bottom end of the second slider is threadedly connected to a second fixing bolt.
[0009] As an optional solution to the technical solution of this application, the top end of the first socket block is threaded with a third fixing bolt, and the top end of the second socket block is threaded with a fourth fixing bolt.
[0010] As an optional solution to the technical solution of this application, a limit bolt is threadedly connected at the center of the top right side of the active frame.
[0011] As an optional solution to the technical solution of this application, a buffer pad is fixedly connected to the inner side of the left end of the outer slide groove.
[0012] This invention also discloses a method for moving a movable grid-connected inverter motherboard structure as described in any of the above descriptions, comprising:
[0013] Step S10: Adjust the position of slider number one in the inner groove to fit the length of the motherboard.
[0014] Step S20: Adjust the position of the second slider on the support frame so that the limiting block at the top of the second slider corresponds to the four corners of the main board, and place the four corners of the main board in the limiting block.
[0015] Step S30: Adjust the position of the first socket block on the active frame so that it corresponds to the position of the support frame below.
[0016] Step S40: Move the second socket block on the sliding connecting block to correspond to the limiting block below.
[0017] In step S50, after the movable frame is pressed down, the rubber pads at the bottom of the second socket block press down on the four corners of the motherboard, completing the installation and ensuring the stability of the motherboard.
[0018] Compared with the prior art, the beneficial effects of this application are as follows:
[0019] 1. This application uses a first slider, a second slider, a first socket block, and a second socket block to fix the motherboard. The position of the first slider in the inner groove is adjusted to fit the length of the motherboard. Then, the position of the second slider is adjusted so that the limiting block at the top of the second slider aligns with the four corners of the motherboard. Next, the position of the first socket block on the movable frame is adjusted so that it aligns with the position of the support frame below. Finally, the position of the second socket block on the sliding connecting block is aligned with the limiting block below. After the movable frame is pressed down, the rubber pad at the bottom of the second socket block presses down on the four corners of the motherboard, thus completing the installation and ensuring the stability of the motherboard. Furthermore, this mechanism can be freely adjusted according to the size of the motherboard, adapting to the fixing of different motherboards and improving adaptability and practicality.
[0020] 2. This application facilitates the movement of the motherboard through the outer slide groove and sliding frame. After the motherboard is installed, the front and rear sides of the sliding frame are pushed into the outer slide groove along the outer slide groove. When disassembly is required, the sliding frame can be pulled out. Therefore, it is not necessary to disassemble the entire inverter. The number of screws used is very small, the probability of loss is low, and the practicality and maintenance efficiency of the device are improved. Attached Figure Description

If the specific posture changes, the directional indications will also change accordingly.
[0031] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0032] See Figures 1 to 5 This invention discloses a movable grid-connected inverter motherboard structure, including a housing 1, a sliding frame 3, a movable frame 8, a support frame 5, and a connecting rod 10. The front and rear inner walls of the housing 1 are provided with outer sliding grooves 2. The front and rear sides of the sliding frame 3 are laterally connected within the outer sliding grooves 2. After the motherboard is installed, the front and rear sides of the sliding frame 3 are pushed into the outer sliding grooves 2. When disassembly is needed, the sliding frame 3 can be pulled out, thus eliminating the need to disassemble the entire inverter, making operation convenient. The front and rear inner walls of the sliding frame 3 are provided with inner sliding grooves 301. Two first sliders 4 are slidably connected to the inner side of the inner sliding grooves 301. The first sliders 4 are fixedly connected to both ends of the support frame 5 on both sides. Two second sliders 7 are slidably connected to the surface of the support frame 5. A limit block 6 is fixedly connected to the top of the second slider 7. The movable frame 8 is hinged to the left side of the top of the sliding frame 3. Two first sleeve blocks 9 are movably sleeved on the surfaces of the straight rods on the front and rear sides of the movable frame 8. Both ends of the connecting rod 10 are fixedly connected to the first socket block 9 on both sides, and two second socket blocks 11 are movably sleeved on the surface of the connecting rod 10. Rubber pads 12 are fixedly connected to the bottom of the second socket block 11. The first socket block 9, the second socket block 11, the first slider 4, and the second slider 7 fix and clamp the four corners of the main board from the top and bottom, respectively, thereby ensuring the stability of the main board. It can also be freely adjusted according to the size of the main board, adapting to the fixing of different main boards and improving adaptability and practicality.
[0033] Specifically, such as Figure 2 As shown, a baffle 13 is fixedly connected to the right side surface of the sliding frame 3. Two fixing plates 14 are fixedly connected to the upper edge of the right side wall of the baffle 13. The fixing plates 14 on the baffle 13 can fix the sliding frame 3 in the outer sliding groove 2, thereby maintaining stability.
[0034] It is worth noting that, such as Figure 4 and Figure 5As shown, the top of slider 4 is threaded with a fixing bolt 401, and the bottom of slider 7 is threaded with a fixing bolt 501. When the fixing bolt 401 is tightened, slider 401 is fixed in its current position. When the fixing bolt 501 is tightened, slider 7 is fixed in its current position on the support frame 5.
[0035] It is worth noting that, such as Figure 4 As shown, the top of the first socket block 9 is threaded with the third fixing bolt 901, and the top of the second socket block 11 is threaded with the fourth fixing bolt 111.
[0036] It is worth noting that, such as Figure 2 As shown, a limit bolt 801 is threadedly connected at the center of the right side of the top of the movable frame 8. After the third fixing bolt 901 is tightened, the first socket block 9 is fixed in the current position. After the fourth fixing bolt 111 is tightened, the second socket block 11 is fixed in the current position of the connecting rod 10.
[0037] It is worth noting that, such as Figure 3 As shown, a buffer pad 201 is fixedly connected to the inner side of the left end of the outer slide 2. The buffer pad 201 can buffer the left end of the sliding frame 3 when it slides in, thereby protecting the motherboard and reducing the vibration caused by the impact.
[0038] The present invention also discloses a method for moving a movable grid-connected inverter motherboard structure, which is applied to a movable grid-connected inverter motherboard structure in any of the above embodiments.
[0039] Specifically, the method for moving a movable grid-connected inverter motherboard structure disclosed in this invention includes at least the following steps.
[0040] Step S10: Adjust the position of slider 4 in the inner groove 301 to accommodate the length of the motherboard.
[0041] Step S20: Adjust the position of the second slider 7 on the support frame 5 so that the limiting block 6 at the top of the second slider 7 corresponds to the four corners of the main board, and place the four corners of the main board in the limiting block 6.
[0042] Step S30: Adjust the position of the first socket block 9 on the active frame 8 so that it corresponds to the position of the support frame 5 below.
[0043] Step S40: Move the second socket block 11 on the sliding connecting block to correspond to the limiting block 6 below.
[0044] In step S50, after the movable frame 8 is pressed down, the rubber pad 12 at the bottom of the second socket block 11 presses down the four corners of the motherboard, completing the installation and ensuring the stability of the motherboard.
[0045] In summary, this invention discloses a movable grid-connected inverter motherboard structure and its moving method. The method involves adjusting the position of slider 4 in the inner sliding groove 301 to accommodate the length of the motherboard, then adjusting the position of slider 7 on the support frame 5 so that the limiting block 6 at the top of slider 7 corresponds to the four corners of the motherboard, placing the four corners of the motherboard in the limiting block 6. Next, the position of socket 9 on the movable frame 8 is adjusted to correspond to the position of the support frame 5 below. Then, the position of socket 11 on the sliding connecting block is adjusted to correspond to the limiting block 6 below. After the movable frame 8 is pressed down, the rubber pad 12 at the bottom of socket 11 presses down on the four corners of the motherboard, thus completing the installation and ensuring the stability of the motherboard.
[0046] Therefore, it can be freely adjusted according to the size of the motherboard, adapting to the fixing of different motherboards, improving adaptability and practicality. After the motherboard is installed, push the front and rear sides of the sliding frame 3 into the outer sliding groove 2 along the outer sliding groove 2. When disassembly is required, simply pull out the sliding frame 3. This eliminates the need to disassemble the entire inverter, improving the practicality and maintenance efficiency of the device. During the pulling process, the connecting wires between the motherboard and the equipment are reserved with sufficient length, so there is no need to worry about pulling the wires and causing the circuit to break.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
[0048] Furthermore, the use of "and / or" or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies both A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
