Description

Technical Field

[0001] This invention relates to the field of inverter technology, specifically to a photovoltaic-storage inverter that is easy to install on a mounting bracket. Background Technology

[0002] Energy storage inverters play a crucial role in increasing the self-consumption rate of photovoltaic (PV) power and ensuring off-grid applications. They not only efficiently convert direct current (DC) to alternating current (AC), but also play a vital role in PV power generation systems. By optimizing the performance of energy storage inverters, we can further improve the efficiency of PV power generation, thereby effectively increasing the self-consumption rate. For off-grid applications, energy storage inverters are indispensable, ensuring stable operation of the system even without grid connection. They can adjust the load impedance to maximize the power output of solar panels. When the solar system is disconnected from the main grid, the inverter can detect this and take appropriate measures to protect the system and personnel from electric shock and equipment damage. The inverter can also filter and rectify the DC voltage from the solar panels, converting it into a stable AC voltage for residential or commercial use. PV inverters play a key role in PV systems, not only improving power quality and system efficiency but also ensuring power safety and stability.

[0003] When using existing photovoltaic-storage inverters, the electricity generated by the photovoltaic system during the day is first used by the load, and the excess is stored in the battery. At night, when the photovoltaic system stops generating electricity, the electricity in the battery provides power to the load, thereby reducing the demand on the grid or completely disconnecting from the grid. When installing existing photovoltaic-storage inverters, screw holes are drilled in the device body and screws are used to connect and fix the device to the bracket. This method is prone to causing damage to the surface of the device and affects its aesthetics. Summary of the Invention

[0004] The purpose of this invention is to provide a photovoltaic-storage inverter that is easy to install on a bracket, in order to solve the problem mentioned in the background art that the existing photovoltaic-storage inverters are installed on a bracket by drilling screw holes in the device body and then using screws to connect and fix the device to the bracket. This method is prone to causing damage to the surface of the device and affecting its aesthetics.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic-storage inverter that is easy to install on a mounting bracket, comprising:

[0006] The device body includes a device body, and a display panel is provided on the surface of the device body.

[0007] The back of the device body is connected to an assembly structure, which includes an L-shaped positioning frame. A bracket positioning plate is inserted inside the bottom end of the L-shaped positioning frame. An L-shaped hinge plate is hinged to the top end of the bracket positioning plate. A first fixing screw is inserted inside the bottom end of the L-shaped hinge plate. A first limiting nut is rotatably connected to the outer surface of one end of the first fixing screw. A device support horizontal plate is connected to the bottom end of the bracket positioning plate. Device support vertical plates are sleeved on the outer walls of both ends of the device support horizontal plate. A second fixing screw is inserted inside one side of the device support vertical plate. A second limiting nut is rotatably connected to the outer surface of one end of the second fixing screw.

[0008] Preferably, the L-shaped hinge plate is sleeved on the inner and outer walls of the top of the L-shaped positioning frame, and one end of the first fixing screw is connected to the surface of the L-shaped positioning frame.

[0009] Preferably, the L-shaped hinge plate has a groove on its surface, and the first fixing screw is inserted into the groove of the L-shaped hinge plate. The first fixing screw and the first limiting nut are rotatably connected by a thread.

[0010] Preferably, a groove is provided on one side of the equipment support vertical plate, and one end of the equipment support horizontal plate is inserted into the groove provided in the equipment support vertical plate and slidably connected to the equipment support vertical plate.

[0011] Preferably, a through groove is provided on one side of the inner wall of the sliding groove of the equipment support vertical plate, the second fixing screw is inserted into the through groove of the equipment support vertical plate, one end of the second fixing screw is connected to one side of the surface of the equipment support horizontal plate, and the second fixing screw and the second limiting nut are rotatably connected by threads.

[0012] Preferably, the upper and lower ends of the equipment support vertical plate are provided with adjustment mechanisms. The adjustment mechanism includes a limit slider, the top of the limit slider is connected to a screw limit ring, the inner surface of the screw limit ring is connected to a limit bearing, the inner surface of the limit bearing is connected to a bracket adjustment screw, and a rubber pad ring is provided on the outer surface of one end of the bracket adjustment screw.

[0013] Preferably, the upper and lower surfaces of the equipment support vertical plate are provided with movable grooves, and the limiting slider is inserted into the movable groove of the equipment support vertical plate and slidably connected to the equipment support vertical plate.

[0014] Preferably, the equipment support vertical plate has through holes at both the upper and lower ends, and one end of the bracket adjusting screw is inserted into the through hole of the equipment support vertical plate.

[0015] Preferably, an annular groove is formed on the surface of the through hole outlet of the equipment support vertical plate, and the rubber gasket is disposed inside the annular groove of the equipment support vertical plate.

[0016] Preferably, the rubber gasket ring is used to buffer the surface of the equipment support plate and the wall, and the screw limit ring and the bracket adjusting screw are movably connected by a limit bearing.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By inserting the bracket positioning plate connected to the top of the equipment support horizontal plate into the L-shaped positioning frame, and then adjusting the angle of the L-shaped hinge plate so that it fits onto the outer wall of the top of the L-shaped positioning frame, and inserting the first fixing screw into the groove of the L-shaped hinge plate to position the L-shaped positioning frame, the first limiting nut is then rotated and connected to the outer surface of one end of the first fixing screw to limit the angle of the L-shaped hinge plate, thereby connecting and fixing the L-shaped hinge plate and the L-shaped positioning frame. Then, the height of the equipment support vertical plate is adjusted so that it moves with the equipment support horizontal plate and the second fixing screw as the limit. After adjustment, the second limiting nut is rotated and connected to the outer surface of one end of the second fixing screw, and the second limiting nut is locked with threads, thereby limiting the position of the equipment support vertical plate. This allows for quick assembly between the equipment body and the equipment support vertical plate, and can be adjusted according to the pre-set screw hole position on the wall, avoiding the problem of increased damage to the surface of the equipment body and affecting its aesthetics when drilling screw holes on the equipment body and then re-drilling.

[0019] 2. By moving the position of the screw limit ring, the limit slider slides within the movable groove of the equipment support vertical plate, thereby adjusting the position of the bracket adjusting screw. One end of the bracket adjusting screw is inserted into the through hole of the equipment support vertical plate, positioning that end. During installation, the angle of the bracket adjusting screw is rotated, causing one end to rotatably connect to the pre-set screw hole in the wall. A limit bearing ensures that the rotation of the bracket adjusting screw does not affect the angle of the screw limit ring, reducing friction between the screw limit ring and the bracket adjusting screw, increasing service life. A rubber gasket buffers the equipment support vertical plate and the wall, ensuring flexible contact and protecting the equipment support vertical plate, thus achieving a limiting effect between the equipment support vertical plate and the wall.

[0029] 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.

[0030] Please see Figure 1-8 One embodiment provided by the present invention:

[0031] A photovoltaic-storage inverter that is easy to install in a mounting bracket includes:

[0032] The device body 1 includes a device body 11. A display panel 12 is provided on the surface of the device body 11. The surface material of the device body 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are made.

[0033] The back of the equipment body 11 is connected to an assembly structure 2, which includes an L-shaped positioning frame 21. A bracket positioning plate 22 is inserted inside the bottom of the L-shaped positioning frame 21. An L-shaped hinge plate 23 is hinged to the top of the bracket positioning plate 22. A first fixing screw 24 is inserted inside the bottom of the L-shaped hinge plate 23. A first limiting nut 25 is rotatably connected to the outer surface of one end of the first fixing screw 24. An equipment support horizontal plate 26 is connected to the bottom of the bracket positioning plate 22. Equipment support vertical plates 27 are sleeved on the outer walls of both ends of the equipment support horizontal plate 26. A second fixing screw 28 is inserted inside one side of the equipment support vertical plate 27. A second limiting nut 29 is rotatably connected to the outer surface of one end of the second fixing screw 28.

[0034] Furthermore, the L-shaped hinge plate 23 is sleeved on the inner and outer walls of the top of the L-shaped positioning frame 21, and one end of the first fixing screw 24 is connected to the surface of the L-shaped positioning frame 21, so that one end of the first fixing screw 24 is fixed by the L-shaped positioning frame 21, thereby using the first fixing screw 24 to position and support the L-shaped hinge plate 23, and using the first fixing screw 24 in conjunction with the first limiting nut 25 to clamp and fix the L-shaped hinge plate 23.

[0035] Furthermore, the L-shaped hinge plate 23 has a groove on its surface, and the first fixing screw 24 is inserted into the groove of the L-shaped hinge plate 23. The first fixing screw 24 and the first limiting nut 25 are connected by a thread, so as to limit the connection between the first fixing screw 24 and the first limiting nut 25 by the thread, thereby connecting and fixing the L-shaped hinge plate 23 and the L-shaped positioning frame 21. The bracket positioning plate 22, the L-shaped hinge plate 23 and the equipment support cross plate 26 form a rectangular structure to wrap around and position the L-shaped positioning frame 21, thereby making the connection more stable.

[0036] Furthermore, a groove is provided on one side of the equipment support vertical plate 27, and one end of the equipment support horizontal plate 26 is inserted into the groove of the equipment support vertical plate 27 and slidably connected to the equipment support vertical plate 27. This allows the equipment support vertical plate 27 to slide on the surface of the equipment support horizontal plate 26 through the groove of the equipment support vertical plate 27, and restricts the movable range of the equipment support vertical plate 27 by the equipment support horizontal plate 26, preventing the equipment support vertical plate 27 from detaching from the equipment support horizontal plate 26.

[0037] Furthermore, a through groove is provided on one side of the inner wall of the sliding groove opened in the equipment support vertical plate 27. The second fixing screw 28 is inserted into the through groove opened in the equipment support vertical plate 27. One end of the second fixing screw 28 is connected to one side of the surface of the equipment support horizontal plate 26. The second fixing screw 28 and the second limiting nut 29 are rotated and connected by threads, so as to achieve the connection and fixation between the second fixing screw 28 and the second limiting nut 29 through threads, thereby achieving the clamping and fixing effect of the equipment support vertical plate 27. By reducing the distance between the equipment support horizontal plate 26 and the second limiting nut 29, the equipment support vertical plate 27 is tightened, so that the equipment support vertical plate 27 cannot move.

[0038] Furthermore, adjustment mechanisms 3 are inserted inside the upper and lower ends of the equipment support vertical plate 27. The adjustment mechanism 3 includes a limit slider 31, a screw limit ring 32 connected to the top of the limit slider 31, a limit bearing 33 connected to the inner surface of the screw limit ring 32, a bracket adjustment screw 34 connected to the inner surface of the limit bearing 33, and a rubber pad ring 35 provided on the outer surface of one end of the bracket adjustment screw 34. By adjusting the position of the bracket adjustment screw 34, the equipment support vertical plate 27 and the wall are limited, thereby using the equipment support vertical plate 27 to limit and support the equipment body 11.

[0039] Furthermore, movable grooves are provided on the upper and lower surfaces of the equipment support vertical plate 27. The limiting slider 31 is inserted into the movable groove of the equipment support vertical plate 27 and slidably connected to the equipment support vertical plate 27. This allows the limiting slider 31 to be moved and limited by the movable groove of the equipment support vertical plate 27. The limiting slider 31 is used to control the movable distance of the screw limiting ring 32 and to prevent the screw limiting ring 32 from detaching from the equipment support vertical plate 27. This ensures that the equipment support vertical plate 27 can only move within the movable range of the limiting slider 31.

[0040] Furthermore, through holes are provided at both the upper and lower ends of the surface of the equipment support vertical plate 27. One end of the bracket adjusting screw 34 is inserted into the through hole of the equipment support vertical plate 27, so that one end of the bracket adjusting screw 34 is positioned through the through hole of the equipment support vertical plate 27. Then, the bracket adjusting screw 34 is used to connect and fix the equipment support vertical plate 27 to the wall, thereby restricting and supporting the equipment body 11 by fixing the position of the equipment support vertical plate 27, so that the equipment body 11 will not move.

[0041] Furthermore, an annular groove is formed on the surface of the through hole outlet of the equipment support vertical plate 27. The rubber pad ring 35 is set inside the annular groove of the equipment support vertical plate 27. The annular groove of the equipment support vertical plate 27 limits the rubber pad ring 35 and uses the rubber pad ring 35 to buffer the equipment support vertical plate 27 and the wall, so that the two are in flexible contact, thereby protecting the equipment support vertical plate 27 and the wall and avoiding damage to both, which would affect the stability of the installation.

[0042] Furthermore, the rubber gasket 35 is used to buffer the surface of the equipment support vertical plate 27 between it and the wall. The screw limit ring 32 and the bracket adjusting screw 34 are movably connected by the limit bearing 33. This ensures that the rotation of the bracket adjusting screw 34 through the limit bearing 33 does not affect the angle of the screw limit ring 32, reducing friction between the screw limit ring 32 and the bracket adjusting screw 34, improving the service life of the threaded limit ring 32, and increasing the service life of the bracket adjusting screw 34. It also avoids the problem of stripping due to inaccurate mating angle of the bracket adjusting screw 34, which would affect the installation firmness.

[0043] Working principle: When the photovoltaic-storage inverter is installed on the bracket, the bracket positioning plate 22 connected to the top of the equipment support plate 26 is inserted into the L-shaped positioning frame 21. Then, the angle of the L-shaped hinge plate 23 is adjusted so that it fits onto the outer wall of the top of the L-shaped positioning frame 21, and the first fixing screw 24 is inserted into the groove of the L-shaped hinge plate 23 to position the L-shaped positioning frame 21. Then, the first limiting nut 25 is rotatably connected to the outer surface of one end of the first fixing screw 24 to limit the angle of the L-shaped hinge plate 23, thereby positioning the L-shaped hinge. The plate 23 and the L-shaped positioning frame 21 are connected and fixed. Then, the height of the equipment support vertical plate 27 is adjusted so that it can move with the equipment support horizontal plate 26 and the second fixing screw 28 as the limit. After the adjustment is completed, the second limit nut 29 is rotatably connected to the outer surface of one end of the second fixing screw 28. The second limit nut 29 is locked with the thread, thereby limiting the position of the equipment support vertical plate 27, so as to achieve the effect of quick assembly between the equipment body 11 and the equipment support vertical plate 27, and can be adjusted according to the position of the screw hole preset in the wall.

[0044] When limiting the position of the photovoltaic-storage inverter that is easy to install on the bracket, the position of the moving screw limit ring 32 is adjusted so that the limit slider 31 slides inside the movable groove opened in the equipment support vertical plate 27, thereby adjusting the position of the bracket adjusting screw 34. One end of the bracket adjusting screw 34 is inserted into the through hole opened in the equipment support vertical plate 27 to position one end of the bracket adjusting screw 34. During installation, the angle of the bracket adjusting screw 34 is rotated so that one end of the bracket adjusting screw 34 is rotatably connected to the pre-set screw hole in the wall. The limit bearing 33 is used to ensure that the rotation of the bracket adjusting screw 34 does not affect the angle of the screw limit ring 32, reducing the friction between the screw limit ring 32 and the bracket adjusting screw 34, increasing the service life. The rubber pad ring 35 is used to buffer the equipment support vertical plate 27 and the wall, making the contact between the two flexible and protecting the equipment support vertical plate 27, thereby achieving the limiting effect between the equipment support vertical plate 27 and the wall.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
