Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , a wall-mounted photovoltaic inverter, including a photovoltaic inverter mechanism 1, and a fixing mechanism 2 is installed on the back of the photovoltaic inverter mechanism 1;

[0027] The photovoltaic inverter mechanism 1 includes an inverter box body 101, an inverter is installed inside the inverter box body 101, hooks 102 are fixedly connected to both the upper and lower sides of the back of the inverter box body 101, and limit fixing holes 103 are opened on the hooks 102;

[0028] The fixing mechanism 2 includes a support guide rail 201, the length of the support guide rail 201 is greater than the length of the hook 102, and the hook 102 is inserted into the inside of the support guide rail 201 and fixed by bolts. Fixing clamping plates 202 are fixedly connected to both sides of the bottom of the support guide rail 201. A rotatable threaded rod 203 is installed between the fixing clamping plates 202, and two symmetrically distributed movable clamping plates 204 are driven on the threaded rod 203. The two movable clamping plates 204 move in opposite directions to form a clamping force with the adjacent fixing clamping plates 202.

[0029] Through the above technical solution, the support guide rail 201 and the hook 102 are arranged to cooperate to support and fix the inverter box body 101 and connect them with bolts. Then, the fixed clamping plate 202 and the movable clamping plate 204 at the bottom of the support guide rail 201 cooperate to form a clamping force and clamp on structures such as curtain wall keels and support beams, achieving the effect of being fixable on the photovoltaic curtain wall.

[0030] Whether it is the front or the back of the curtain wall, there are generally vertically installed support frames for fixing the curtain wall. This device just takes advantage of this to fix the inverter, reducing the distance between the inverter and the photovoltaic panel and reducing the amount of cable used.

[0031] Specifically, the thread rotation directions at both ends of the threaded rod 203 are opposite, and the middle of the threaded rod 203 is a smooth surface.

[0032] Through the above technical solution, the directions of the threads on both sides of the threaded rod 203 are set, so that when the threaded rod 203 is rotated on any side, the movable clamping plates 204 on both sides can approach or move away from the fixed clamping plate 202 simultaneously, forming synchronous clamping and loosening. The purpose of not setting threads in the middle of the threaded rod 203 is to limit the maximum stroke of the threaded rod 203.

[0033] Specifically, both ends of the threaded rod 203 are fixedly connected with adjusting parts 205. The adjusting parts 205 are located on the outer surface of the fixed clamping plate 202, and the adjusting parts 205 are internal hexagonal heads.

[0034] Through the above technical solution, adjusting parts 205 are arranged at both ends of the threaded rod 203, so that during installation, the threaded rod 203 can be rotated from any side, achieving the effect of convenient fixation. If the adjusting parts 205 are internal hexagonal heads, it can avoid slipping and facilitate operation when rotating the threaded rod 203. If the adjusting parts 205 are nuts, it is inconvenient to use tools such as wrenches to tighten due to the small operating space, resulting in unstable fixation.

[0035] Specifically, a wiring cavity 104 is arranged at the bottom of the front of the inverter box body 101, and the outer surface of the wiring cavity 104 is covered with a cover 105.

[0036] Through the above technical solution, the purpose of setting the wiring cavity 104 is to facilitate wiring and connection, and when wiring, the redundant cables can be placed inside the wiring cavity 104 for storage, avoiding the wires from being too taut. Once the wires are too taut, the wire joint positions are severely stressed and prone to falling off. The cover 105 provided is used to protect the cables.

[0037] Specifically, a fixed auxiliary mechanism 3 is installed between the hooks 102 on the back of the inverter box body 101, and the fixed auxiliary mechanism 3 fits with the curtain wall surface to increase the friction force.

[0038] Through the above technical solution, the purpose of setting the fixed auxiliary mechanism 3 is to further improve the clamping stability of the fixed clamping plate 202. By additionally providing friction force through the fixed auxiliary mechanism 3, it is ensured that the entire device is not easily dropped.

[0039] Specifically, the fixed auxiliary mechanism 3 includes a connecting plate 301. The connecting plate 301 is installed on the back of the inverter box body 101 by bolts. A number of support sleeves 302 are installed on the connecting plate 301. A connecting suction cup 303 is arranged inside the support sleeve 302, and the connecting suction cup 303 is lapped with the outer surface of the curtain wall.

[0040] Through the above technical solution, the connecting plate 301 is installed in a bolted manner, so that the connecting plate 301 can be disassembled and assembled according to requirements, improving the convenience of use. The support sleeve 302 and the connecting suction cup 303 are matched with each other. The support sleeve 302 is used to support the connecting suction cup 303, and the connecting suction cup 303 is used to adsorb on the surface of a smooth object.

[0041] During use, by setting the support guide rail 201 and the hook 102 to cooperate, the inverter box body 101 is supported and fixed and connected by bolts. Then, through the cooperation of the fixed clamping plate 202 and the movable clamping plate 204 at the bottom of the support guide rail 201, a clamping force is formed and clamped on structures such as curtain wall keels and support beams, achieving the effect of being fixable on a photovoltaic curtain wall.

[0042] By installing a detachable connecting plate 301 on the back of the inverter box body 101 and fixedly connecting the support sleeve 302 and the connecting suction cup 303 on the connecting plate 301, when the fixing surface is relatively smooth, it can be adsorbed on the outer surface of the smooth surface through the connecting suction cup 303, and the adsorption force is converted into friction force to improve the fixing stability of the entire device.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
