Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and in particular to a control device for a distributed photovoltaic power station. Background Technology

[0002] Distributed photovoltaic (PV) power stations refer to PV power generation systems built on the user side, consuming electricity nearby, and with a relatively small installed capacity. Their system architecture can be divided into five main modules: power generation unit, conversion unit, control unit, distribution unit, and energy storage unit. The control cabinet, as the main structure of the control unit, is usually bolted to the base, making its assembly and disassembly inconvenient. Summary of the Invention

[0003] The purpose of this application is to provide a control device for a distributed photovoltaic power station, which aims to solve the technical problem of inconvenient disassembly and assembly caused by the bolt-fixing method used in the control cabinet in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution: A distributed photovoltaic power station control device includes a control cabinet and a base. A limiting part at the bottom of the control cabinet is slidably engaged with a limiting groove on the base. A swing arm is hinged to the limiting part. The swing arm is slidably engaged with a positioning post inserted into the limiting part. The swing arm can push the positioning post to insert into a positioning hole formed in the limiting groove.

[0005] By adopting the technical solution of this application, the movement of the control cabinet relative to the base is restricted by the sliding snap-fit ​​between the control cabinet and the base, and by the plug-in fit between the positioning column and the positioning hole. This solves the technical problem of inconvenient disassembly and assembly caused by the bolt-fitting method of the control cabinet.

[0006] Furthermore, the limiting part is constructed in a T-shape along the cross section to fit the shape of the limiting groove.

[0007] Furthermore, the limiting part is provided with a mounting groove for mounting the swing arm.

[0008] Furthermore, the bottom of the control cabinet is provided with a clearance opening corresponding to the mounting slot.

[0009] Furthermore, the swing arm is constructed in a U-shape.

[0010] Furthermore, the two ends of the swing arm are provided with pivots that can be inserted into the side walls of the mounting slot.

[0011] Furthermore, the side wall of the swing arm is provided with a groove that engages with the positioning column groove.

[0012] Furthermore, the extension direction of the chute is arranged perpendicular to the axis of the pivot.

[0013] Furthermore, the positioning post is equipped with sliders on both sides that engage with the sliding groove.

[0014] Furthermore, the side wall of the mounting slot is provided with a stop that can engage with the swing arm. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0017] Please see Figs. 1 to 3 In this embodiment of the application, a distributed photovoltaic power station control device is provided, which includes a control cabinet 10 and a base 20. The limiting part 11 at the bottom of the control cabinet 10 is slidably engaged with the limiting groove 21 on the base 20. A swing arm 13 is hinged on the limiting part 11. The swing arm 13 is slidably engaged with the positioning post 14 inserted into the limiting part 11. The swing arm 13 can push the positioning post 14 to be inserted into the positioning hole 22 formed in the limiting groove 21.

[0018] The limiting part 11 is fixedly connected to the bottom surface of the control cabinet 10. The limiting part 11 is constructed into a T-shape along the cross section. Specifically, the limiting part 11 is arranged along the longitudinal direction of the bottom surface of the control cabinet 10 and is located at the middle position in the width direction of the bottom surface of the control cabinet 10.

[0019] An installation groove 12 is provided on the top surface of the limiting part 11. The installation groove 12 is arranged along the longitudinal direction of the limiting part 11. Specifically, the installation groove 12 is constructed into a rectangular groove shape. A clearance opening corresponding to the installation groove 12 is provided on the bottom plate of the control cabinet 10. The installation groove 12 is connected to the internal space of the control cabinet 10 through the clearance opening.

[0020] The swing arm 13 is hinged inside the mounting slot 12. When the swing arm 13 swings upward, it can move into the control cabinet 10 through the clearance opening. Specifically, the swing arm 13 is constructed in a U-shape. Pivots 132 are fixedly connected to both ends of the swing arm 13. The pivots 132 are inserted into the side wall of the corresponding mounting slot 12, so that the swing arm 13 can swing around the axis of the pivot 132 inside the mounting slot 12.

[0021] A sliding groove 131 is provided on the side wall of the swing arm 13, and the extension direction of the sliding groove 131 is arranged perpendicular to the axis of the pivot 132. The positioning post 14 is movably inserted into the bottom of the mounting groove 12. A slider 141 is fixedly connected to the side wall of the positioning post 14. The slider 141 is slidably engaged inside the sliding groove 131. When the swing arm 13 rotates, it can drive the positioning post 14 to move up and down in the vertical direction.

[0022] An elastic stop 121 is fixed on the side wall of the mounting groove 12. For example, the stop 121 is made of rubber. The stop 121 is located on the side where the movable end of the swing arm 13 is located. When the swing arm 13 swings downward, it can move to the bottom of the stop 121. The stop 121 is used to prevent the swing arm 13 from moving upward, thereby restricting the swing arm 13 inside the mounting groove 12.

[0023] It should be noted that when the swing arm 13 is rotated up and down with force, the swing arm 13 can pass over the stop block 121.

[0024] A limiting groove 21 is formed on the top surface of the base 20. The limiting groove 21 is constructed into a T-shape that matches the shape of the limiting part 11. A positioning hole 22 is provided at the bottom of the limiting groove 21. The positioning hole 22 is arranged correspondingly to the positioning post 14.

[0025] When the limiting part 11 is inserted into the limiting groove 21, the control cabinet 10 is slidably restricted on the base 20. As the limiting part 11 moves out of the limiting groove 21, the control cabinet 10 can be moved out of the base 20. When the control cabinet 10 moves along the limiting groove 21 to the position corresponding to the positioning post 14 and the positioning hole 22, the swing arm 13 is swung downward, which can push the positioning post 14 vertically downward into the positioning hole 22. This restricts the sliding of the control cabinet 10 on the base 20 and ensures the stability of the control cabinet 10 installed on the base 20.

[0026] The distributed photovoltaic power station control device provided in this application embodiment restricts the movement of the control cabinet 10 relative to the base 20 by sliding and snapping together the control cabinet 10 and the base 20, and by using the insertion and connection between the positioning column 14 and the positioning hole 22. This solves the technical problem of inconvenient disassembly and assembly caused by the bolted fixing method of the control cabinet in the prior art.

[0027] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
