[0029] In order to make the technical solution and advantages of the utility model clearer, the utility model and its beneficial effects will be further described in detail below in combination with specific implementation methods and drawings of the specification, but the implementation methods of the utility model are not limited thereto.
[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
[0032] like Figures 1 to 9 As shown, a fan mounting assembly includes a base 1 and a mounting frame 2, wherein the base 1 is used to be connected and fixed to a photovoltaic inverter 5, and the mounting frame 2 is provided with a plurality of fixing seats 3 for mounting the fan along the length direction, and openings 11 are provided on both sides of the base 1, and rotating shafts 21 that can pass through the openings 11 on the same side and cooperate with each other are provided on both sides of the mounting frame 2. The mounting frame 2 can rotate on the mounting frame 2 to a closed state and an open state with the rotating shaft 21 as the axis through the cooperation between the rotating shaft 21 and the opening 11.
[0033] Specifically, fans are installed in the fixing seat 3, rotating shafts 21 are provided at both ends of the installation frame 2, openings 11 are provided on both sides of the base 1, and the openings 11 are close to the front side of the base 1. Two rotating shafts 21 are respectively inserted into the openings 11 on both sides of the base 1. When the rotating shafts 21 are placed in the openings 11, the installation frame 2 is rotated to be parallel to the base 1 and in a closed state, so that the two sides of the fan of the fixing seat 3 are respectively facing the photovoltaic inverter 5 and the outside, and the installation of the fan is completed. When it is necessary to maintain one or more fans in the fixing seat 3, first rotate the installation frame 290 degrees or 180 degrees to an open state, and the fans in the fixing seat 3 are exposed to the outside, and the fans that need maintenance can be maintained, and the corresponding fans can be disassembled and replaced. Since the mounting frame 2 is rotatably connected by the cooperation of the rotating shaft 21 and the opening 11, the position of the rotating shaft 21 in the opening 11 can be adjusted in real time during the rotation of the mounting frame 2, so that the rotation trajectory of the mounting frame 2 as a whole can be adjusted, thereby effectively reducing the installation space of the fan assembly and reducing the impact of the limited operable space. The fan is installed on the photovoltaic inverter 5 by the mounting assembly, and no specific tools are required for disassembly, so tool-free installation can be achieved, further improving the simplicity of fan maintenance work.
[0034] In some embodiments of the present application, the openings 11 are all L-shaped. Specifically, the structural design of the L-shaped opening 11 is that when the mounting frame 2 is in a closed state, the rotating shaft 21 is located inside the opening 11, the L-shaped opening 11 limits the rotating shaft 21, and the side of the mounting frame 2 away from the opening 11 is also in contact with the photovoltaic inverter 5, preventing the rotating shaft 21 from moving outward along the opening 11 after the mounting frame 2 is closed, thereby ensuring the stability of the mounting frame 2 after closing.
[0035] In some embodiments of the present application, a support portion 12 is provided on one side of the base 1 away from the opening 11, and the support portion 12 contacts and cooperates with the installation frame 2 to support the installation frame 2 in a closed state. Specifically, after the installation frame 2 is closed, the lower rear side of the installation frame 2 abuts against the support portion 12, and the rear side of the installation frame 2 is supported by the support portion 12, so that the installation frame 2 is in a horizontal state after closing, and the installation frame 2 is prevented from tilting to one side, thereby ensuring the normal operation of the fan and a good heat dissipation effect.
[0036] In some embodiments of the present application, the photovoltaic inverter has a card slot 51 on one side close to the base 1, and also includes a card connector 4, which is movably arranged on the mounting frame 2, and can be movably inserted into the card slot 51 for limiting and pulled out from the card slot 51. Specifically, the card connector 4 can move closer to and away from the card slot 51, and when the mounting frame 2 rotates to abut against the support portion 12 and is in a closed state, the card connector 4 is controlled to move and insert into the card slot 51 of the photovoltaic inverter 5, so as to achieve the purpose of fixing, prevent the mounting frame 2 from rotating after closing, and ensure the stability of the fan operation.
[0037] In some embodiments of the present application, the clamping member 4 includes a slide 41, a latch 42 and an elastic plate 43. A movable hole 22 is provided on the mounting frame 2. The slide 41 is movably matched in the movable hole 22. The latch 42 is provided on one side of the slide 41 for inserting into the slot 51 for matching. The elastic plate 43 is provided on one side of the slide 41 close to the base 1, and the two ends of the elastic plate 43 are respectively abutted against the opposite side walls of the mounting frame 2. Specifically, the slide 41 can slide forward in the movable hole 22 to approach the photovoltaic inverter 5, or slide backward to move away from the photovoltaic inverter 5. The latch 42 is located at the front side of the slide 41, and the elastic plate 43 is located at the lower part of the slide 41. When the latch tongue 42 is inserted into the slot 51, the elastic plate 43 is in the initial state. When the control slide 41 moves toward the rear side, the elastic plate 43 is squeezed and deformed. At this time, the latch tongue 42 is pulled out of the slot 51 along with the movement of the slide 41, and the mounting frame 2 can be rotated to the open state. Then the elastic plate 43 is reset to drive the slide 41 and the latch tongue 42 to move and reset. When the mounting frame 2 needs to be rotated to the closed state, the moving slide 41 can slide toward the rear side, and the slide 41 is reset by the elastic plate 43, which drives the latch tongue 42 to move and insert into the slot 51, thereby completing the fixation purpose.
[0038] In some embodiments of the present application, a groove 411 is formed on the top of the slide 41, and a handle 412 is provided in the groove 411. Specifically, the provision of the handle 412 is more conducive to the user pulling the slide 41 for operation, which is more labor-saving.
[0039] In some embodiments of the present application, a plurality of clamping members 4 are provided, and the plurality of clamping members 4 are respectively located between two adjacent fixing seats 3. Specifically, the gaps between the fixing seats 3 are each provided with a clamping member 4, and the fixing seats 3 and the clamping member 4 are arranged in sequence, and a reasonable distribution design between the clamping member 4 and the fixing seats 3 avoids occupying too much area, while further improving the fixing stability of the installation frame 2 when it is in a closed state.
[0040] In some embodiments of the present application, the fixing base 3 is detachably connected to the mounting frame 2. Specifically, the detachable connection between the fixing base 3 and the mounting frame 2 allows the fixing base 3 on which the fan is mounted to be directly disassembled when the fan fails and is inconvenient to disassemble, and then the fan is disassembled for repair, or a new fixing base 3 and fan installation are replaced, thereby improving the convenience and efficiency of fan maintenance.
[0041] A photovoltaic inverter 5 includes the above-mentioned fan installation assembly. Compared with the existing pull-out and detachable fan installation solutions, both of which require professional tools to remove screws and require sufficient tool operation space, the fan installation assembly can be maintained without using special tools, greatly reducing the limitation of the operation space, making the maintenance of the photovoltaic inverter 5 fan more convenient.
[0042] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
