DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following Figures 1-3 further elaborates on the present application in detail.

[0029] The embodiment of the present application discloses an installation structure of a photovoltaic inverter.

[0030] Referring to Figure 1 , the installation structure includes a photovoltaic inverter 1 and an installation frame 2.

[0031] Referring to Figure 1 and Figure 2, the photovoltaic inverter 1 includes an installation shell 11, installation columns 12, a plurality of installation plates 13 and a plurality of installation screws 14, and each component of the photovoltaic inverter 1 is installed in the installation shell 11. The installation columns 12 are arranged in a rectangular column shape, and the installation columns 12 are fixedly connected to the lower end of the installation shell 11. The plurality of installation plates 13 are respectively fixedly connected to both sides of the installation shell 11, and the number of installation screws 14 matches the number of installation plates 13.

[0032] The installation frame 2 includes a frame body 21, two rotating members 22 and a support seat 23. The frame body 21 is vertically placed on the ground. Both rotating members 22 are rotatably connected to one side of the frame body 21, and the two rotating members 22 are arranged at intervals along the width direction of the frame body 21. One end of the support seat 23 is fixedly connected to the frame body 21 on the side where the rotating member 22 is located, and the support seat 23 is located below the rotating member 22 for the installation shell 11 to be horizontally placed.

[0033] Among them, when the photovoltaic inverter 1 is installed, both ends of the installation column 12 are respectively fixedly connected to the two rotating members 22. The installation shell 11 is vertically arranged and one side abuts against the frame body 21, so that the plurality of installation plates 13 abut against the frame body 21, and each installation screw 14 passes through each installation plate 13 and is threadedly connected to the frame body 21 to realize the fixation of the installation shell 11, thereby realizing the installation of the photovoltaic inverter 1.

[0034] When installing the photovoltaic inverter 1, the support seat 23 is horizontally arranged. The staff first horizontally places the installation shell 11 on the upper side of the support seat 23, so that there is a distance between the installation column 12 and the upper side of the support seat 23, and the lower end of the installation shell 11 is close to the frame body 21. Then, the installation shell 11 is slid to make the installation column 12 close to the two rotating members 22, and both ends of the installation column 12 are respectively fixedly connected to the two rotating members 22. At this time, a force is applied to the upper end of the installation shell 11, and the rotation of the installation shell 11 is realized by using the two rotating members 22. The installation shell 11 rotates from the horizontal state to the vertical state, so that each installation plate 13 abuts against the frame body 21, and then the installation screws 14 are passed through the installation plates 13 and locked to the frame body 21, and the installation of the photovoltaic inverter 1 can be realized.

[0035] Among them, since the lower end of the installation shell 11 is limited to the two rotating members 22 through the installation column 12, only a slight force needs to be applied to the upper end of the installation shell 11 by one hand of a staff member to avoid the displacement of the photovoltaic inverter 1 as much as possible, so that the other hand of the staff member can lock the installation screws 14, thereby facilitating the installation of the photovoltaic inverter 1.

[0036] Refer to Figure 1 and Figure 3, in some embodiments, the rotating member 22 includes a rotating shaft 221, a sliding sleeve 222, and a first spring 223. The rotating shaft 221 is rotatably connected to the frame 21. The sliding sleeve 222 is slidably connected to one end of the rotating shaft 221 close to the other rotating shaft 221. The sliding direction is the length direction of the rotating shaft 221. One end of the first spring 223 is fixedly connected to the end of the sliding sleeve 222 close to the frame 21, and the other end is fixedly connected to the frame 21 to drive the sliding sleeve 222 away from the rotating shaft 221. Moreover, the cavity of the sliding sleeve 222 is adapted to the mounting post 12, so that one end of the mounting post 12 can be inserted and fixed in the sliding sleeve 222. In practical applications, by pressing the two sliding sleeves 222 and then sliding the mounting shell 11 on the support base 23, the mounting posts 12 of the mounting shell 11 and the two sliding sleeves 222 are made to be in the same straight line. Each sliding sleeve 222 is reset under the drive of each first spring 223, so that both ends of the mounting post 12 are respectively inserted and fixed in the two sliding sleeves 222, realizing the fixed connection between the mounting post 12 and the two rotating members 22. The structure is simple and the operation is convenient, thus facilitating the installation of the photovoltaic inverter 1.

[0037] In some embodiments, a guiding groove 224 is formed at one end of the sliding sleeve 222 away from the rotating shaft 221. The guiding groove 224 is inclined for the mounting post 12 to abut against. Specifically, during the process of sliding the mounting shell 11, both ends of the mounting post 12 respectively abut against the groove walls of the guiding groove 224. Under the guidance of the guiding groove 224, the sliding sleeve 222 is pressed, eliminating the need for staff to press the sliding sleeve 222, facilitating the insertion and fixation between the mounting post 12 and the sliding sleeve 222, and thus facilitating the installation of the photovoltaic inverter 1.

[0038] Refer to Figure 1 and Figure 2 , in some embodiments, one end of the support base 23 is rotatably connected to the frame 21. The support base 23 has two states and is switched by rotation. Specifically, when the support base 23 is in the first state, the support base 23 is horizontally arranged, and the end of the support base 23 close to the rotation is fixedly connected to the frame 21 to limit the rotation of the support base 23, so that the mounting shell 11 can be stably placed on the upper side of the support base 23. When the support base 23 is in the second state, the support base 23 is vertically arranged, and the end of the support base 23 away from the rotation is fixedly connected to the frame 21. After the installation of the photovoltaic inverter 1 is completed, by rotating the support base 23, the support base 23 is made to be vertically arranged to abut against the frame 21 and the end of the support base 23 away from the rotation is fixedly connected to the frame 21, thereby improving the overall support strength of the mounting frame 2, realizing the storage of the support base 23, effectively reducing the occupied space, and also avoiding the risk of staff being bumped and injured due to the protrusion of the support base 23.

[0039] In some embodiments, the mounting bracket 2 further includes a plurality of pins 24. In this embodiment, two pins 24 are taken as an example for illustration. The two pins 24 are arranged at intervals along the width direction of the frame body 21. When the support seat 23 is in the first state, both of the two pins 24 are inserted into the end of the support seat 23 close to the rotation and the frame body 21 at the same time, so as to fix the support seat 23 and the frame body 21, thereby restricting the rotation of the support seat 23. Among them, the staff can release the fixation between the support seat 23 and the frame body 21 by pulling out the pins 24, so as to facilitate the switching of the state of the support seat 23.

[0040] In some embodiments, the mounting bracket 2 further includes a plurality of fastening bolts 25. In this embodiment, two fastening bolts 25 are taken as an example for illustration. The two fastening bolts 25 are arranged at intervals along the width direction of the frame body 21. When the support seat 23 is in the second state, the two fastening bolts 25 pass through the end of the support seat 23 far from the rotation and are threadedly connected to the frame body 21, so as to facilitate the fixation of the end of the support seat 23 far from the rotation and the frame body 21, and improve the stability of the support for the mounting bracket 2.

[0041] In some embodiments, the mounting bracket 2 further includes a first connecting gear 26 and a second connecting gear 27. The first connecting gear 26 meshes with the second connecting gear 27 and has the same diameter, so that the rotation angle of the first connecting gear 26 is the same as the rotation angle of the second connecting gear 27. The first connecting gear 26 is fixedly connected to the rotating shaft 221, and the second connecting gear 27 is fixedly connected to the rotating shaft of the support seat 23. It should be noted that the number of the first connecting gear 26 and the second gear can be two to improve the stability of the work.

[0042] In practical applications, after the two ends of the mounting column 12 are respectively inserted and fixedly connected to the two sliding sleeves 222, the rotating shaft 221 drives the mounting shell 11 to rotate, so that the mounting shell 11 abuts against the frame body 21. During this process, the rotating shaft 221 drives the first connecting gear 26 to rotate, and the first connecting gear 26 drives the second connecting gear 27 to rotate, so as to drive the support seat 23 to rotate, so that the support seat 23 automatically switches from the first state to the second state, thereby facilitating the installation and use of the photovoltaic inverter 1. Of course, when the pins 24 are removed, due to the certain weight of the support seat 23, under the action of gravity, it can also drive the mounting shell 11 to move upward, thereby further facilitating the installation of the photovoltaic inverter 1.

[0043] Moreover, after the end of the support seat 23 far from the rotation is fixedly connected to the frame body 21, due to the meshing of the first connecting gear 26 and the second connecting gear 27, the rotation of the rotating shaft 221 can be effectively restricted, so as to restrict the rotation of the mounting shell 11, thereby improving the stability of the installation of the photovoltaic inverter 1 and the stability of the use of the photovoltaic inverter 1.

[0044] In some embodiments, the mounting bracket 2 further includes a plurality of pulleys 28. The plurality of pulleys 28 are rotatably connected to the support base 23 and are located on both sides of the support base 23. The pulleys 28 are used to abut against the mounting shell 11 to facilitate the sliding of the mounting shell 11 on the support base 23.

[0045] In some embodiments, the mounting bracket 2 further includes a fastener 29. The fastener 29 includes a fastening plate 291 and a second spring 292. The fastening plate 291 is slidably connected to the frame body 21, and the sliding direction is the vertical direction. The fastening plate 291 is located above the mounting shell 11. The upper end of the second spring 292 is fixedly connected to the frame body 21, and the lower end is fixedly connected to the fastening plate 291 to drive the fastening plate 291 to move downward, that is, to drive the fastening plate 291 to abut against the upper end of the mounting shell 11, so as to facilitate the locking of the mounting screw 14 and improve the installation stability of the photovoltaic inverter 1.

[0046] In some embodiments, the fastener 29 further includes a winding disc 293 and a pulling rope 294. The winding disc 293 is fixedly connected to the rotating shaft 221 to rotate with the rotating shaft 221. The pulling rope 294 is movably threaded through the frame body 21. One end of the pulling rope 294 is fixedly connected to the upper side of the fastening plate 291, and the other end is wound in the winding disc 293. When the support base 23 is in the first state, the pulling rope 294 pulls the fastening plate 291 to move upward, so that the rotated mounting shell 11 abuts against the fastening plate 291. And when the rotating shaft 221 rotates, the winding disc 293 unwinds one end of the pulling rope 294, so that the fastening plate 291 approaches the mounting shell 11 under the drive of the second spring 292, so as to facilitate abutting the fastening plate 291 against the upper end of the mounting shell 11. Among them, the number of the winding disc 293 and the pulling rope 294 is two groups and they are symmetrically arranged to improve the stability of use.

[0047] The implementation principle of this embodiment is as follows: When installing the photovoltaic inverter 1, the support base 23 is horizontally arranged. The staff first horizontally place the mounting shell 11 on the upper side of the support base 23, so that there is a distance between the mounting column 12 and the upper side of the support base 23, and the lower end of the mounting shell 11 is close to the frame body 21. Then slide the mounting shell 11 to make the mounting column 12 approach the two rotating members 22, and fixedly connect the two ends of the mounting column 12 to the two rotating members 22 respectively. At this time, apply a force to the upper end of the mounting shell 11, and use the two rotating members 22 to rotate the mounting shell 11. The mounting shell 11 rotates from the horizontal state to the vertical state, so that each mounting plate 13 abuts against the frame body 21. Then pass the mounting screw 14 through the mounting plate 13 and lock it to the frame body 21 to complete the installation of the photovoltaic inverter 1.

[0048] Among them, since the lower end of the installation shell 11 is limited by the installation posts 12 to the two rotating parts 22, only a slight force needs to be applied to the upper end of the installation shell 11 by one hand of a staff member to avoid the displacement of the photovoltaic inverter 1 as much as possible, so that the other hand of the staff member can lock the installation screw 14, thus facilitating the installation of the photovoltaic inverter 1.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
