Technical Field

[0001] The utility model relates to the technical field of photovoltaic inverters, in particular to a photovoltaic inverter with an installation plate that is easy to disassemble and assemble. Background Art

[0002] Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important system balances in photovoltaic array systems and can be used with general AC-powered equipment.

[0003] In the prior art, photovoltaic panels are usually installed outdoors, and therefore often experience strong winds and heavy rains. The photovoltaic inverters used with the photovoltaic panels will also experience strong winds and heavy rains together with the photovoltaic panels. Therefore, in order to improve the installation strength of the photovoltaic panels, the photovoltaic inverters are usually fixed with bolt fasteners, etc. This installation method requires installers to frequently tighten the fasteners with the help of tools, which is not only cumbersome to install, but also wastes time when disassembling.

An adjustment ring is sleeved on the outer peripheral side of the mounting plate, and the inner side walls of the adjustment ring are protruding on both sides of the latch tooth to form a limiting portion.

[0008] Furthermore, a limiting groove is provided on one side of the mounting plate close to the working groove, and the limiting portion is slidably arranged in the limiting groove.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1 - Figure 7 The utility model discloses a photovoltaic inverter with a mounting plate that is easy to disassemble and assemble, including a mounting plate 1 and a photovoltaic inverter body 2, wherein the four corners of the mounting plate 1 are rotatably connected with a screw rod 3, a side of the inverter body is convexly formed with a connecting portion 4, the four corners of the connecting portion 4 are provided with a positioning groove 5 for inserting the screw rod 3, a ball 6 that contacts the spiral groove of the screw rod 3 is arranged in the positioning groove 5, and a direction-changing component 7 is arranged on the side of the mounting plate 1 close to the screw rod 3.

[0027] In this embodiment, when in use, the mounting plate 1 is fixed to the wall where the photovoltaic inverter body 2 needs to be installed, and then the positioning groove 5 provided on the connecting portion 4 of the photovoltaic inverter body 2 is aligned with the spiral rod 3, and the photovoltaic inverter body 2 is pushed close to the mounting plate 1, and the spiral rod 3 can be inserted into the positioning groove 5 to complete the installation of the photovoltaic inverter body 2.

[0028] When the screw rod 3 enters the positioning groove 5, observe Figure 2 and Figure 3 It can be found that as the depth of the screw rod 3 inserted into the positioning groove 5 increases, the spiral groove of the screw rod 3 will roll under the pressure of the ball 6. Figure 5 As shown, the spiral rod 3 can only rotate counterclockwise through the direction-changing component 7. After the photovoltaic inverter body 2 is installed, the spiral rod 3 cannot be removed due to the unidirectional rotation. While ensuring the installation stability of the photovoltaic inverter body 2, the installation process of the photovoltaic inverter body 2 is simplified.

[0029] As photovoltaic panels are added, the load of the photovoltaic inverter body 2 will also increase, so the photovoltaic inverter body 2 needs to be replaced. The rotation direction of the screw rod 3 is changed by the changing component 7, so that the screw rod 3 can only rotate forward but not reverse. When the screw rod 3 rotates forward, the ball 6 will roll along the spiral groove and move away from the mounting plate 1 along the axial direction of the screw rod 3. Therefore, when the photovoltaic inverter body 2 is pulled, the ball can roll normally in the spiral groove of the screw rod 3, making the disassembly of the photovoltaic inverter body 2 easier, thereby effectively reducing the disassembly efficiency of the photovoltaic inverter body 2 and making the replacement and maintenance efficiency of the photovoltaic inverter body 2 higher.

[0030] In a further preferred embodiment of the present invention, Figure 4 - Figure 6 As shown, the direction-changing assembly 7 includes a gear 71, a latch tooth 72 and an adjustment ring 73. A working groove 8 is provided in the mounting plate 1. A gear 71 is rotatably connected in the working groove 8. One side of the gear 71 is fixedly connected to the spiral rod 3. The working groove 8 is located on one side of the gear 71 and is rotatably connected to a latch tooth 72 for clamping the gear 71 through a clockwork spring. An adjustment ring 73 is sleeved on the outer peripheral side of the mounting plate 1. The inner side walls of the adjustment ring 73 are located on both sides of the latch tooth 72 and are raised to form a limiting portion 9.

[0031] In this embodiment, by providing the latching teeth 72 and the gear 71 , the latching teeth 72 can be used to latch the gear 71 to prevent the gear 71 from rotating, thereby fixing the gear 71 and preventing the spiral rod 3 from rotating.

[0032] And observe Figure 6It can be found that the inner wall of the adjustment ring 73 is connected to the limiting portion 9. When the limiting portion 9 blocks one side of the latch tooth 72, the latch tooth 72 can only rotate toward the side that does not contact the limiting portion 9, and after the gear 71 drives the latch tooth 72 to rotate, the latch tooth 72 will reset under the elastic force of the clockwork spring, so that the latch tooth 72 can always keep in contact with the gear 71 to prevent the gear 71 from being stuck by the latch tooth 72 when it rotates, thereby controlling the unidirectional rotation of the gear 71 to achieve the effect of adjusting the unidirectional rotation of the spiral rod 3.

[0033] In a further preferred embodiment of the present invention, Figure 4 As shown, a limiting groove 10 is opened on one side of the mounting plate 1 close to the working groove 8, and the limiting portion 9 is slidably arranged in the limiting groove 10. When one of the limiting portions 9 contacts the latch tooth 72, the other limiting portion 9 contacts the inner side wall of the limiting groove 10.

[0034] The locking cam 72 is preferably located adjacent to the locking cam 71 and is preferably positioned adjacent to the locking cam 71. The locking cam 72 is preferably located adjacent to the locking cam 71 and is preferably located adjacent to the locking cam 71.

[0035] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the outer wall of the adjustment ring 73 is fixedly connected with a positioning block 11, the outer wall of the positioning block 11 is provided with a through groove 12 and is slidably connected with an insertion rod 13, and the outer wall of the mounting plate 1 is provided with two slots 14 for inserting the insertion rod 13.

[0036] In this embodiment, when the limiting portion 9 blocks the rotation of the latch tooth 72 and the gear 71 is clamped by the latch tooth 72, the pressure generated when the gear 71 rotates and pushes the latch tooth 72 will also be transmitted to the limiting portion 9, thereby pushing the limiting portion 9 away from the latch tooth 72, allowing the gear 71 to resume rotation, affecting the installation stability of the photovoltaic inverter body 2.

[0037] Therefore, a positioning block 11 is provided on one side of the adjustment ring 73, and a through slot 12 is provided in the positioning block 11, and an insertion rod 13 is inserted in the through slot 12. At the same time, a slot 14 for inserting the insertion rod 13 is provided on the mounting plate 1, so that when the insertion rod 13 is inserted into the slot 14, the adjustment ring 73 is fixed to prevent the pressure exerted by the gear 71 on the latch tooth 72 from pushing the limit portion 9 open.

[0038] And observe Figure 4 It can be found that when the insertion rod 13 is inserted into the slot 14 located below the side wall of the mounting plate 1, the limit portion 9 contacts the clockwise direction of the latch tooth 72, which is used to prevent the latch tooth 72 from rotating clockwise, so that the gear 71 is restricted by the latch tooth 72 and cannot rotate counterclockwise, so that the spiral rod 3 can only rotate in the clockwise direction, which can be used for the rapid disassembly of the photovoltaic inverter body 2.

[0039] And observe Figure 5 It can be found that when the insertion rod 13 is pushed up, the insertion rod 13 is inserted into the slot 14 located above the side wall of the mounting plate 1. During the process of pushing the insertion rod 13 up, the insertion rod 13 will push the positioning block 11 to move up, thereby using the positioning block 11 to push the adjustment ring 73 to move, so that the limiting portion 9 in the limiting groove 10 moves, thereby changing the limiting portion 9 in contact with the latch tooth 72, so that the limiting portion 9 blocks the counterclockwise rotation direction of the latch tooth 72, so that the gear 71 can only rotate in the counterclockwise direction, and the spiral rod 3 can rotate counterclockwise, which is used to quickly install the photovoltaic inverter body 2 on the mounting plate 1.

[0040] In a further preferred embodiment of the present invention, Figure 4 As shown, the distance between the two slots 14 is a distance A15, the distance between the limiting portion 9 away from the latching tooth 72 and the latching tooth 72 is a distance B16, and the distance A15 is equal to the distance B16.

[0041] In this embodiment, by making the distance between the two slots 14 be distance A15, the distance between the limiting portion 9 away from the latch tooth 72 and the latch tooth 72 be distance B16, and making the distance A15 equal to the distance B16, when the position of the insertion rod 13 is adjusted, the limiting portion 9 in contact with the latch tooth 72 can be replaced, thereby changing the rotation direction of the latch tooth 72, making the disassembly and assembly adjustment of the photovoltaic inverter body 2 simpler, and can effectively reduce the installation difficulty of the photovoltaic inverter body 2 and improve the installation efficiency.

[0042] In a further preferred embodiment of the present invention, Figure 7 As shown, the inner wall of the through groove 12 is concave to form a circular groove 17, and a disc 18 fixedly connected to the insertion rod 13 is slidably connected in the circular groove 17, and a supporting spring 19 is arranged between the side of the disc 18 away from the slot 14 and the circular groove 17.

[0043] In this embodiment, a circular groove 17 is opened in the through groove 12, and a disc 18 is slidably connected in the circular groove 17. The circular groove 17 can be used to prevent the disc 18 from escaping from the positioning block 11, and the disc 18 can be used to prevent the insertion rod 13 from escaping from the positioning block 11, so as to prevent the loss of the insertion rod 13.

[0044] A support spring 19 is provided between the side of the disc 18 away from the slot 14 and the circular groove 17. The elastic force of the support spring 19 can be used to push the disc 18 closer to the slot 14, so as to insert the insertion rod 13 into the slot 14, so as to make the connection between the insertion rod 13 and the slot 14 more stable, thereby further improving the installation stability of the photovoltaic inverter body 2.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
