Description

Technical Field

[0001] The invention relates to a photovoltaic inverter mounting structure, in particular to a photovoltaic inverter quick mounting structure. Background Art

[0002] As the application scenarios of photovoltaic inverters continue to diversify, the power density, power level, and single-unit capacity of photovoltaic inverters are becoming increasingly demanding. Compared with the past, the weight of the inverters has continued to increase while the volume remains similar, which has affected the efficiency and difficulty of on-site installation of the inverters.

[0003] At present, the installation efficiency of the photovoltaic inverter mounting structure is low and the one-time mounting success rate is low. For example, in the photovoltaic storage inverter bracket structure patent with application number 2023209709817, the inverter is mounted by plugging and cooperating with the plug plate on the bracket and the slot on the photovoltaic storage inverter heat sink. This structure has high requirements on the accuracy of the sheet metal bending angle and the bending strength of the plug plate, and during the mounting process, the plug plate needs to be accurately inserted into the radiator slot to complete the mounting. Once the inverter is skewed during the mounting and installation process, it is easy to get stuck, and the one-time installation success rate is low.

[0004] Therefore, how to achieve fast mounting of the inverter and improve the one-time installation success rate of the inverter is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In order to solve the problems in the related art, the present application provides a photovoltaic inverter quick mounting structure, which solves the problems of uneven mounting, easy jamming and low installation efficiency.

[0006] The technical solution is as follows:

[0007] A photovoltaic inverter quick-hanging structure comprises a connecting piece and a hanging piece, wherein the hanging piece is used to be installed on the photovoltaic inverter, and the connecting piece is used to be installed on a corresponding mounting piece at the photovoltaic inverter installation location, wherein the connecting piece is provided with at least two supporting pieces, and each supporting piece is rotationally matched with the connecting piece;

[0008] A hanging groove is provided on the hanging member corresponding to each of the supporting members, and each of the hanging grooves includes an entry portion and a fixing portion which are connected to each other, and there is an angle between the entry portion and the fixing portion, and the angle is not equal to 180°. When the hanging member is hung on the connecting member, the supporting member enters the fixing portion through the entry portion, so that the hanging member is hung on the connecting member, and the supporting member and the hanging groove are matched in a rolling state.

[0009] Through the above technical solution, by supporting the member on the connecting member, when installing the inverter, the hanging groove on the hanging member will contact the supporting member along its entry portion and slide along the entry portion to gradually enter the fixed portion. After the supporting member receives the contact force transmitted by the hanging groove, the supporting member will rotate rapidly around the supporting member. When the fixed portion and the top of the supporting member are in contact, the operator can let go. At this time, the rapid hanging of the photovoltaic inverter is completed, thereby accelerating the hanging and installation efficiency of the inverter; in addition, the friction form of the supporting member and the hanging member during the contact between each other is rolling friction, and the friction damping of rolling friction is small, which can avoid the phenomenon of jamming during the installation of the inverter, thereby improving the installation smoothness of the photovoltaic inverter, thereby improving the one-time hanging success rate of the photovoltaic inverter.

[0010] Preferably, the hanger is arranged in a "U" shape, and the hanger includes an integrally formed first main body plate and two hanging plates, both ends of the first main body plate are respectively provided with first fastening holes, and the first fastening holes are through holes, and the two hanging grooves are respectively arranged on the two hanging plates.

[0011] Preferably, the connecting member includes a first connecting plate and at least two support frames, and the number of the support frames is consistent with the number of the support members; each of the support frames is arranged in a "U" shape, and the two support frames include an integrally formed second main body plate and two baffles, each of the second main body plates is fixedly arranged on the first connecting plate, and each of the second main body plates has a second fastening hole arranged in the form of a through hole; each of the support members is arranged between the two baffles in the corresponding support frame, and the length of each of the support members is slightly smaller than the distance between the two baffles.

[0012] Preferably, one of the two hanging plates has a first fixing hole in the shape of a through hole, and a first rivet nut is provided on the first fixing hole; when the hanger is hung on the connecting member, the baffle corresponding to the first fixing hole has a second fixing hole in the shape of a through hole, and the second fixing hole is a waist-shaped hole.

[0013] Through the above technical solution, after the hanger is hung on the connecting part through the corresponding first fixing hole and the second fixing hole, a standard bolt is set on the second fixing hole, and the bolt passes through the second fixing hole and the first fixing hole in turn and is fixed with the first rivet nut. This prevents the hanger from shaking or tilting, thereby ensuring the installation stability of the inverter. The first rivet nut installed by stamping can reduce the difficulty of producing the hanger and reduce the production cost.

[0014] Preferably, limiting holes are provided on the two baffles in each of the support frames, a second rivet nut is provided on one of the limiting holes in each of the support frames, and a shoulder bolt is provided on the other limiting hole in each of the support frames. The shoulder bolt passes through the corresponding support member and is connected to the second rivet nut.

[0015] Through the above technical solution, the support member is set between the two baffles by directly using a standard shoulder bolt, so that the structure of the support frame is simple and the production cost can be reduced; by setting a second shoulder bolt on one of the baffles, when producing the support frame, it can be directly set on the limit hole by stamping, thereby improving production efficiency and reducing installation difficulty.

[0016] Preferably, each of the supporting members is a rolling sleeve or a rolling bearing.

[0017] Preferably, at least one limit plate is integrally formed on one side of the first main body plate close to the connecting member, and each limit plate is arranged along the length direction of the first main body plate; when the hanging plate is hung on the supporting member, the two ends of each limit plate respectively abut against the side wall surfaces of the baffle plates corresponding to both sides.

[0018] Through the above technical solution, through the setting of the limit plate, after the inverter is mounted, the limit plate will be in close contact with the corresponding baffles on both sides due to the action of gravity, which can limit the position of the hanger, thereby avoiding the inverter from tilting, thereby improving the stability of the inverter after mounting.

[0019] Preferably, a second connecting plate and a third connecting plate are provided at the top and bottom ends of the first connecting plate corresponding to two baffles close to each other in two adjacent support frames, and the structures of the second connecting plate and the third connecting plate are consistent. Each second connecting plate and the third connecting plate are arranged along the length direction of the first connecting plate, and the two ends of each second connecting plate and the third connecting plate are respectively against the side wall surface of the corresponding baffle.

[0020] Preferably, each of the second main body plates has a third fixing hole in the shape of a through hole, each of the third fixing holes is provided with a fixing bolt, each of the first connecting plates corresponding to the third fixing holes has a fourth fixing hole in the shape of a through hole, each of the fourth fixing holes is provided with a third rivet nut, and each of the fixing bolts passes through the corresponding third fixing hole and the fourth fixing hole in sequence and is connected with the corresponding third rivet nut.

[0021] Preferably, each of the second fixing plates is welded to the first connecting plate.

[0022] In summary, the beneficial effects of a photovoltaic inverter quick mounting structure are:

[0023] 1. By supporting the part on the connecting part, when installing the inverter, the hanging groove on the hanging part will contact the supporting part along its entry part and slide along the entry part to gradually enter the fixed part. After the supporting part receives the contact force transmitted by the hanging groove, the supporting part will rotate rapidly around the shoulder bolt. When the fixed part and the top of the supporting part are in contact, the operator can let go. At this time, the rapid hanging of the photovoltaic inverter has been completed, thereby speeding up the hanging installation efficiency of the inverter. In addition, the friction form of the supporting part and the hanging part in the process of mutual contact is rolling friction, and the friction damping of rolling friction is small, which can avoid the phenomenon of stuck in the process of inverter installation, thereby improving the installation smoothness of the photovoltaic inverter, thereby improving the success rate of one-time hanging of the photovoltaic inverter;

[0024] 2. After the hanger is hung on the connector through the corresponding first fixing hole and the second fixing hole, a standard bolt is set on the second fixing hole, and the bolt passes through the second fixing hole and the first fixing hole in sequence and is fixed with the first rivet nut. This prevents the hanger from shaking or tilting, thereby ensuring the installation stability of the inverter. The first rivet nut installed by stamping can reduce the difficulty of producing the hanger and reduce the production cost.

[0025] 3. By directly using standard shoulder bolts to set the support between the two baffles, the structure of the support frame is simple and the production cost can be reduced; by setting the second shoulder bolt on one of the baffles, when producing the support frame, it can be directly set on the limit hole by stamping, thereby improving production efficiency and reducing installation difficulty;

[0026] 4. Through the setting of the limit plate, after the inverter is mounted, the limit plate will be in close contact with the corresponding baffles on both sides due to gravity, which can limit the position of the hanger, thereby avoiding the inverter from tilting, thereby improving the stability of the inverter after mounting.
