Description

Technical Field

[0001] This utility model relates to the field of solar inverter technology, specifically a solar inverter device. Background Technology

[0002] Against the backdrop of global energy structure transformation, solar energy, as an inexhaustible renewable energy source, is receiving increasing attention and importance. As the core equipment in a solar photovoltaic power generation system, the solar inverter undertakes the crucial task of converting the direct current (DC) generated by solar panels into alternating current (AC) for use by various electrical devices in homes, industries, and other sectors. Its performance and reliability directly affect the operating efficiency and stability of the entire solar photovoltaic power generation system.

[0003] Most existing solar inverter devices lack effective physical protection structures. In practical applications, solar inverters are usually installed in outdoor environments, such as rooftops and open spaces. These places are easily affected by various external objects. For example, in severe weather conditions, tree branches, hail, and other objects may fall and hit the inverter. During construction or equipment maintenance, tools, debris, and other objects may accidentally collide with the inverter. Due to the lack of necessary protective plates and other physical protection measures, the inverter's casing is easily damaged, which can lead to the exposure of internal circuit components, increasing the risk of short circuits, leakage, and other safety hazards. It may even render the entire inverter unusable, causing economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a solar inverter device to solve the problem mentioned in the background art that most existing solar inverter devices lack effective physical protection structures. In practical application scenarios, solar inverters are usually installed in outdoor environments, such as rooftops and open spaces. These places are easily affected by various external objects. For example, in severe weather conditions, tree branches, hail, and other objects may fall and hit the inverter. During construction or equipment maintenance, tools, debris, etc. may accidentally collide with the inverter. Due to the lack of necessary protective plates and other physical protection measures, the inverter casing is easily damaged, which leads to the exposure of internal circuit components, increasing the safety risks of short circuits, leakage, etc., and may even render the entire inverter unusable, causing economic losses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar inverter device, comprising an inverter body, with protective plates at the top and bottom, and side plates at the center of both sides of the inverter body. The two protective plates, positioned vertically and horizontally, each have a snap-fit ​​groove on one side near their respective ends. Snap-fit ​​plates are fixedly connected to the top and bottom of the inverter body on both sides near their respective ends. The side of the snap-fit ​​plate away from the inverter body extends into the snap-fit ​​groove and snaps into it. Each of the two snap-fit ​​plates has a snap-fit ​​groove on one side near its respective end. The protective plate has an arc-shaped fixing groove, and a movable groove is opened near the center position inside the protective plate. Movable plates are slidably connected to both sides of the movable groove. The center of the opposite ends of the two movable plates on the left and right is fixedly connected to an arc-shaped fixing plate. The side of the arc-shaped fixing plate away from the movable plate passes through the interior of the arc-shaped fixing groove and engages with the arc-shaped fixing groove. The two protective plates on the upper and lower sides of the opposite ends have positioning grooves. The top and bottom of the side plate are fixedly connected to positioning plates. The side of the positioning plate away from the side plate passes through the interior of the positioning groove and engages with the positioning groove.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This solar inverter features protective plates at the top and bottom of the inverter body, and side plates at the center of both sides. When objects such as tree branches or hail fall on the inverter outdoors, or tools or debris accidentally collide with it during construction or equipment maintenance, these protective plates and side plates form the first line of physical protection. They directly withstand the impact of external objects, preventing the impact from directly affecting the inverter's casing. This effectively prevents damage to the inverter casing, protects internal circuit components from exposure, reduces the risk of short circuits and leakage, and minimizes economic losses caused by inverter failure due to casing damage. The protective pads provide cushioning protection: two pads are installed at the top and bottom. Protective pads are fixedly connected to both sides of the protective plate at opposite ends. When an external object impacts the protective plate, the protective pads act as a buffer, absorbing part of the impact energy through their elastic deformation, further reducing the impact force on the protective plate and the inverter body, enhancing the impact resistance of the entire device, and improving the protection effect. The two protective plates, one above the other, have snap-fit ​​grooves on both sides of their opposite ends. Snap-fit ​​plates are fixedly connected to both sides of the top and bottom of the inverter body. The side of the snap-fit ​​plate away from the inverter body extends into the snap-fit ​​groove and snaps into it. This snap-fit ​​method is simple and secure, allowing for quick installation of the protective plate onto the inverter body. Furthermore, the snap-fit ​​structure ensures that the protective plate remains firmly in place even under external impact. It effectively resists impact forces, prevents the protective plate from separating from the inverter body, and ensures that the protective plate can continuously perform its protective function. Each of the two snap-fit ​​plates has an arc-shaped fixing groove on one side facing each other. A movable groove is located near the center of the protective plate, with movable plates slidably connected to both sides of the movable groove. An arc-shaped fixing plate is fixedly connected to the center of the opposite ends of the two movable plates. The side of the arc-shaped fixing plate away from the movable plate extends into the arc-shaped fixing groove and snaps into it. This secondary fixing structure further enhances the connection stability between the protective plate and the inverter body. When the snap-fit ​​plates and snap-fit ​​grooves are subjected to impact forces, the snap-fit ​​between the arc-shaped fixing plates and the arc-shaped fixing grooves provides additional support to prevent separation. The structure is loose, ensuring that the protective plate always fits tightly against the inverter body. Slide grooves are provided on both sides of the top of the movable slot inside the protective plate. A sliding plate is fixedly connected to the top of the movable plate. The side of the sliding plate away from the movable plate extends into the interior of the slide groove and engages with it. A limit rod is fixedly connected to the center of the slide groove. The limit rod is sleeved and slidably connected to the sliding plate. During the movement of the arc-shaped fixed plate, the sliding plate slides within the slide groove. The limit rod guides and limits the sliding of the sliding plate, ensuring that the arc-shaped fixed plate can accurately engage with the arc-shaped fixed slot. Furthermore, under impact, the slide groove and limit rod can limit excessive displacement of the sliding plate, preventing the arc-shaped fixed plate from detaching from the arc-shaped fixed slot and ensuring the stability of the secondary fixing structure.

[0017] A center plate 14 is fixedly connected to the center of the movable groove 8. Support grooves 15 are opened on the center of the opposite side of the two movable plates 9 arranged on the left and right. Support rods 16 are fixedly connected to the center of both sides of the center plate 14. The side of the support rod 16 away from the center plate 14 passes through the interior of the support groove 15 and is slidably connected to the support groove 15.

[0018] A return spring 17 is fitted on the surface of the support rod 16, and the two sides of the return spring 17 are fixedly connected to the movable plate 9 and the center plate 14 respectively.

[0019] The top of the positioning groove 18 is fixedly connected to the built-in plate 20, and the bottom center of the built-in plate 20 is fixedly connected to the limiting plate 22. The top center of the positioning plate 19 has a limiting groove 21, and the bottom of the limiting plate 22 extends into the interior of the limiting groove 21 and engages with the limiting groove 21.

[0020] A magnetic block 23 is fixedly connected to the bottom of the limiting groove 21, and an iron plate 24 is fixedly connected to the bottom of the limiting plate 22. The bottom of the iron plate 24 is magnetically connected to the top of the magnetic block 23.

[0021] Working principle: Place the inverter body 1 in a suitable position, preparing to install the protective plate 2. Align the snap-fit ​​plates 6 on the top and bottom of the inverter body 1 with the snap-fit ​​slots 5 on the opposite sides of the upper and lower protective plates 2. Push the protective plate 2 so that the side of the snap-fit ​​plate 6 away from the inverter body 1 passes through the snap-fit ​​slot 5. At this time, the snap-fit ​​plate 6 and the snap-fit ​​slot 5 are initially snapped together, realizing the initial positioning and connection between the protective plate 2 and the inverter body 1. Inside the protective plate 2, a center plate 14 is fixed in the center of the movable slot 8. Support rods 16 are fixedly connected to the center of both sides of the center plate 14. The side of the support rod 16 away from the center plate 14 passes through the support slot 15 opened in the center of the opposite side of the movable plate 9 and slides through the support slot 15. Furthermore, a return spring 17 is sleeved on the surface of the support rod 16. The two sides of the return spring 17 are fixedly connected to the movable plate 9 and the center plate 14, respectively. A sliding plate 12 is fixed on the top of the movable plate 9. The side of the sliding plate 12 away from the movable plate 9 extends into the sliding groove 11 opened on both sides of the top of the movable groove 8 inside the protective plate 2 and engages with the sliding groove 11. A limit rod 13 is fixed in the center of the sliding groove 11. The limit rod 13 is sleeved with the sliding plate 12 and slidably connected. In the initial state, the return spring 17 is in a natural state, and the movable plate 9 is in a specific position under the elastic force of the return spring 17. When the engaging plate 6 is engaged into the engaging groove 5, the operator presses the movable plates 9 on the left and right sides towards the center plate 14. The movable plate 9 drives the sliding plate 12 to move in the sliding groove 11. Slide along the limiting rod 13, while the movable plate 9 slides on the support rod 16 and compresses the return spring 17. When the movable plate 9 moves to the appropriate position, the arc-shaped fixing plate 10 moves with the movable plate 9 to the corresponding position of the arc-shaped fixing groove 7 opened on the opposite side of the snap-fit ​​plate 6. Release the movable plate 9, and the elastic force of the return spring 17 causes the movable plate 9 to return to its original position, driving the arc-shaped fixing plate 10 to pass through the arc-shaped fixing groove 7 and snap into the arc-shaped fixing groove 7, further fixing the protective plate 2 to the inverter body 1 and preventing the protective plate 2 from falling off. Align the positioning plates 19 at the top and bottom of the side plate 3 with the positioning grooves 18 opened on the opposite sides of the upper and lower protective plates 2, respectively, and push the side plate 3 so that the side of the positioning plate 19 away from the side plate 3 passes through the positioning groove 18. At this point, the positioning plate 19 and the positioning groove 18 are initially engaged, achieving the initial positioning connection between the side plate 3 and the protective plate 2. An inner plate 20 is fixed to the top of the positioning groove 18, and a limiting plate 22 is fixedly connected to the bottom center of the inner plate 20. A limiting groove 21 is opened at the top center of the positioning plate 19. When the positioning plate 19 is engaged in the positioning groove 18, the bottom of the limiting plate 22 penetrates into the limiting groove 21. A magnetic block 23 is fixed to the bottom of the limiting groove 21, and an iron sheet 24 is fixed to the bottom of the limiting plate 22. The bottom of the iron sheet 24 is magnetically connected to the top of the magnetic block 23. The limiting plate 22 and the limiting groove 21 are further fixed by magnetic adsorption, thereby enhancing the connection stability between the side plate 3 and the protective plate 2 and preventing the side plate 3 from shaking or falling off.

[0022] In summary, this solar inverter device, by installing protective plates 2 at the top and bottom of the inverter body 1 and side plates 3 at the center of both sides, forms the first line of physical defense when objects such as tree branches or hail fall on the inverter in the outdoor environment, or when tools or debris accidentally collide with the inverter during construction or equipment maintenance. These plates directly withstand the impact of external objects, preventing the impact force from directly acting on the inverter body 1's casing, thus effectively preventing damage to the inverter casing, protecting internal circuit components from exposure risks, reducing safety risks such as short circuits and leakage, and minimizing economic losses caused by inverter scrapping due to casing damage. The protective pads 4 provide buffer protection: the two protective plates 2 positioned at the top and bottom... Protective pads 4 are fixedly connected to both sides of one end of the protective plate 2. When an external object impacts the protective plate 2, the protective pads 4 can act as a buffer. They absorb part of the impact energy through their own elastic deformation, further reducing the impact force on the protective plate 2 and the inverter body 1, enhancing the impact resistance of the entire device, and improving the protection effect. The two protective plates 2, which are set at the top and bottom, are provided with snap-fit ​​grooves 5 on both sides of opposite ends. Snap-fit ​​plates 6 are fixedly connected to both sides of the top and bottom of the inverter body 1. The side of the snap-fit ​​plate 6 away from the inverter body 1 extends into the snap-fit ​​groove 5 and snaps into the snap-fit ​​groove 5. This snap-fit ​​method is simple and firm, allowing the protective plate 2 to be quickly installed on the inverter body 1. Furthermore, when subjected to external impact, the snap-fit ​​structure can effectively withstand the impact. To resist impact and prevent the protective plate 2 from separating from the inverter body 1, ensuring the continuous protective function of the protective plate 2, each of the two snap-fit ​​plates 6 has an arc-shaped fixing groove 7 on one side opposite to the other. A movable groove 8 is located near the center of the protective plate 2, with movable plates 9 slidably connected to both sides of the movable groove 8. An arc-shaped fixing plate 10 is fixedly connected to the center of the opposite ends of the two movable plates 9. The side of the arc-shaped fixing plate 10 away from the movable plate 9 extends into the arc-shaped fixing groove 7 and snaps into it. This secondary fixing structure further enhances the connection stability between the protective plate 2 and the inverter body 1. When the snap-fit ​​plate 6 and the snap-fit ​​groove 5 are subjected to impact, the snap-fit ​​between the arc-shaped fixing plate 10 and the arc-shaped fixing groove 7 provides additional support, preventing impact. To prevent the locking structure from loosening, the protective plate 2 is always tightly fitted to the inverter body 1. Slide grooves 11 are provided on both sides of the top of the movable groove 8 inside the protective plate 2. A sliding plate 12 is fixedly connected to the top of the movable plate 9. The side of the sliding plate 12 away from the movable plate 9 extends into the interior of the slide groove 11 and engages with it. A limiting rod 13 is fixedly connected to the center of the slide groove 11. The limiting rod 13 is sleeved and slidably connected to the sliding plate 12. During the movement of the arc-shaped fixed plate 10, the sliding plate 12 slides within the slide groove 11. The limiting rod 13 guides and limits the sliding of the sliding plate 12, ensuring that the arc-shaped fixed plate 10 can accurately engage with the arc-shaped fixed groove 7. Furthermore, when subjected to impact, the slide groove 11 and the limiting rod 13 can limit the excessive displacement of the sliding plate 12.To prevent the arc-shaped fixing plate 10 from detaching from the arc-shaped fixing groove 7, and to ensure the stability of the secondary fixing structure.
