[0039] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be considered as part of the specification. In order to overcome the problems of the prior art that the installation structure of the capacitor plate is installed using positioning components such as bolts and screws, the entire installation process is complicated, the installation efficiency is low, and the cost is high. Figures 1 to 4As shown, on one hand, the utility model provides a capacitor plate mounting structure of a photovoltaic inverter, including a photovoltaic inverter bottom shell 1 and a clamping portion 4 mounted on the photovoltaic inverter bottom shell 1, the photovoltaic inverter bottom shell 1 is formed with a mounting groove 3 for accommodating a capacitor plate 2, and the clamping portion 4 is configured to be able to clamp and cooperate with the clamping groove portion on the capacitor plate 2 accommodated in the mounting groove 3, so as to clamp and fix the capacitor plate 2 into the mounting groove 3.

[0040] Combination Figures 1 to 3 As shown, when the capacitor plate 2 needs to be assembled to the photovoltaic inverter base shell 1, the capacitor plate 2 can be first installed in the mounting groove 3, and then the clamping part 4 is clamped into the clamping groove part on the capacitor plate 2, so that the capacitor plate 2 can be fixed to the mounting groove 3 to complete the assembly. The entire installation process is simple, which is convenient for quick assembly of the capacitor plate 2 and improves the installation efficiency.

[0041] In some embodiments, the clamping portion 4 includes a movable plate 41 arranged on the bottom shell 1 of the photovoltaic inverter, a guide portion 42, and a clamping column 43 having one end connected to the movable plate 41 and the other end capable of being clamped into the clamping groove portion. The guide portion 42 and the clamping column 43 are arranged on both sides of the movable plate 41 opposite to each other, and the guide portion 42 can pull the movable plate 41 to move in a direction toward or away from the mounting groove 3.

[0042] Specifically, under the traction of the guide portion 42 , the movable plate 41 can be moved to drive the clamping column 43 to move, so that the clamping column 43 can be inserted into the clamping slot and clamped with the capacitor plate 2 , so that the capacitor plate 2 is clamped and fixed to the installation slot 3 .

[0043] Among them, refer to Figure 2 As shown, the guide portion 42 includes a spring member 421, and the two ends of the spring member 421 are respectively abutted against the moving plate 41 and the bottom shell 1 of the photovoltaic inverter. The spring member 421 can pull the moving plate 41 to prevent the clamping column 43 from being loosened after being inserted into the clamping groove. Of course, it is not limited to using the spring member 421 to pull the moving plate 41. A connecting block 422 can also be connected to the side of the moving plate 41 away from the clamping column 43, and a damper can be set, and the two ends of the damper are respectively abutted against the bottom shell 1 of the photovoltaic inverter and the connecting block 422, and the moving plate 41 is pulled by the damper.

[0044] Furthermore, it also includes a connecting rod with two ends respectively abutting against the moving plate 41 and the photovoltaic inverter bottom shell 1, and the spring member 421 is sleeved on the connecting rod. It can be understood that the spring member 421 can be sleeved on the connecting rod to prevent the spring member 421 from bending.

[0045] Wherein, in some embodiments, combined Figure 2 and Figure 3As shown, a groove 5 for accommodating the clamping portion 4 is formed on the bottom shell 1 of the photovoltaic inverter, and a through hole 6 is formed on the side of the groove 5 facing the mounting groove 3. The through hole 6 is adapted to the clamping slot portion to allow the clamping column 43 to pass through the through hole 6 and be clamped into the clamping slot portion to fix the capacitor plate 2.

[0046] Specifically, combined Figure 2 and Figure 3 As shown, after the capacitor plate 2 is placed in the mounting groove 3, the through hole 6 opened in the groove 5 toward the mounting groove 3 is on the same horizontal line as the card slot portion on the capacitor plate 2 and has the same diameter, so that the card column 43 passes through the through hole 6 and is carded into the card slot portion to be fixed; and the card portion 4 can be placed in the groove 5 for easy concealment to avoid exposure to the outside and damage.

[0047] Furthermore, combined with Figure 1 and Figure 2 As shown, the movable plate 41 is installed in the groove 5 and the top end protrudes from the surface of the groove 5, one end of the guide part 42 is connected to the inner wall of the groove 5, and the other end is connected to the movable plate 41. It can be understood that the top end of the movable plate 41 protrudes from the surface of the groove 5, which is convenient for the operator to manually pull the movable plate 41, so that the clamping column 43 can be inserted into or pulled out of the clamping groove, thereby facilitating the assembly or disassembly of the capacitor plate 2. In addition, the guide part 42 and the clamping column 43 are on the same horizontal line, which is convenient for pulling the movable plate 41, preventing the clamping column 43 from loosening from the clamping groove, and thus achieving the fixation of the capacitor plate 2.

[0048] Wherein, in some embodiments, reference Figures 1 to 3 As shown, it includes at least two groups of clamping parts 4 arranged opposite to each other at both ends of the installation groove 3. Such arrangement can improve the overall stability of the installation of the capacitor plate 2 and avoid displacement or unstable installation of the capacitor plate 2 caused by unbalanced force.

[0049] Wherein, in some embodiments, combined Figure 2 and Figure 3 As shown, the inner wall of the mounting groove 3 is formed with an annular step 31, the capacitor plate 2 is connected to the annular step 31, and the portion surrounded by the annular step 31 is formed with a sinking groove 32 that sinks toward the bottom of the photovoltaic inverter bottom shell 1, and a heat dissipation component 7 is installed in the sinking groove 32.

[0050] Specifically, since the capacitor plate 2 releases heat when working, the working temperature has an important influence on the performance and life of the photovoltaic inverter. Therefore, a heat dissipation component 7 can be arranged below the capacitor plate 2 to dissipate heat, thereby reducing the working temperature of the photovoltaic inverter. To this end, an annular step 31 can be arranged along the inner peripheral wall of the installation groove 3, and the capacitor plate 2 is connected to the annular step 31, so that a sinking groove 32 is formed along the portion surrounded by the annular step 31, so as to reserve space for installing the heat dissipation component 7 below the capacitor plate 2.

[0051] Preferably, the bottom of the sinking groove 32 at least partially penetrates the photovoltaic inverter bottom shell 1 to form a heat dissipation hole 8, so that when the heat dissipation operation of the capacitor plate 2 is performed by the heat dissipation component 7, the hot air in the installation groove 3 can be quickly circulated and discharged through the heat dissipation hole 8, thereby reducing the heat of the photovoltaic inverter bottom shell 1 and the capacitor plate 2 themselves, and improving the performance and life of the photovoltaic inverter.

[0052] Wherein, in some embodiments, reference Figure 4 As shown, the heat dissipation assembly 7 includes a plurality of heat dissipation blades 71 and a drive motor 72 for driving the heat dissipation blades 71 to rotate and dissipate heat from the capacitor plate 2. Figure 4 As shown, the output end of the driving motor 72 is connected to the first gear 75, a plurality of heat dissipation blades 71 are arranged at intervals, and a second gear 76 meshing with the first gear 75 is arranged at the bottom of one of the heat dissipation blades 71, and the plurality of heat dissipation blades 71 are all arranged on the rotating wheel 73, and the conveyor belt 74 is sleeved on the rotating wheel 73.

[0053] Specifically, when the capacitor plate 2 needs to be cooled, the drive motor 72 can be started to drive the first gear 75 to rotate, thereby driving the second gear 76 meshing with the first gear 75 to rotate. The rotation of the second gear 76 drives the heat dissipation blades 71 and the rotating wheel 73 connected thereto to rotate, and then the conveyor belt 74 mounted on the rotating wheel 73 rotates synchronously, so that multiple heat dissipation blades 71 all rotate to cool the capacitor plate 2.

[0054] Another aspect of the utility model provides a photovoltaic inverter, which includes the capacitor plate mounting structure of the photovoltaic inverter.
