Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a control device for photovoltaic power generation. Background Technology

[0002] A solar photovoltaic power generation system mainly consists of solar photovoltaic power generation modules, batteries, controllers, and inverters. In order to control these components in the photovoltaic power generation system, corresponding control devices are required.

[0003] A distributed photovoltaic power generation system integrated control device, as disclosed in CN215186037U, includes a housing, a battery, an inverter, a controller, and a control panel. The battery, inverter, and controller are all installed inside the housing. The control panel is mounted on the front side wall of the housing. Support rods are detachably mounted on both sides of the bottom of the housing. A hollow plate is fixedly mounted at the center of the bottom of the housing. Two arc-shaped clamping plates are symmetrically arranged below the hollow plate. A rotating mechanism for moving the two arc-shaped clamping plates is installed inside the hollow plate. This control device is small in size, easy to install and carry, and allows the housing to be installed in different locations. However, while this control device can be well applied, it is typically only usable when clamped to a rod, making it difficult to securely place it on the ground for operation. Furthermore, the control device does not facilitate automatic adjustment of the controller angle, making it difficult to operate from different angles, often causing inconvenience to users. Utility Model Content

[0004] The purpose of this utility model is to provide a control device for photovoltaic power generation, in order to solve the problems mentioned in the background art that although the control device can be used well, it can usually only be used by clamping it on the pole, and it is difficult to place it stably on the ground for operation. In addition, the control device is not convenient for automatically adjusting the angle of the controller, and it is difficult to operate the control device from different angle areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control device for photovoltaic power generation, comprising a base frame, a lower seat body mounted on the top of the base frame, support frames on both sides of the top of the lower seat body, an upper seat body fixed to the top of the support frames, a rotating shaft rotatably mounted at the center of the interior of the upper seat body, a gear being provided at the bottom end of the rotating shaft extending to the outside of the upper seat body, a disc being provided at the top of the rotating shaft extending to the outside of the upper seat body, a control box being provided at the top of the disc, a wireless receiving module being provided at the center of the top of the control box, a controller being mounted on one side of the surface of the control box, and a component frame being provided on the surface of the control box on one side of the controller.

[0006] Preferably, top frames are provided on both inner walls of the top of the base frame, and two diagonal bracing legs are installed on the outer surfaces of both sides of the base frame. Positioning pins are installed on the upper ends of the surfaces of the diagonal bracing legs, and four reinforcing ribs are provided on the inner walls of the base frame. The diagonal bracing legs are provided to cooperate with the base frame to stably place the control device.

[0007] Preferably, a telescopic drive component is mounted on one side of the bottom end of the upper body via a bracket. One end of the telescopic drive component is provided with a rack, which meshes with a gear. The telescopic drive component is provided to drive the rack to move horizontally.

[0008] Preferably, a lead screw is rotatably mounted inside the placement frame, and guide rods are fixed inside the placement frame on both sides of the lead screw. The guide rods are used to limit the movement range of the linkage plate.

[0009] Preferably, a rotary drive component is installed at the bottom end of the placement frame, and the top end of the rotary drive component is connected to the bottom end of the lead screw. The rotary drive component is configured to drive the lead screw to rotate.

[0010] Preferably, a linkage plate is threadedly installed on the outer wall of the upper end of the lead screw. The linkage plate is movably connected to the guide rod. A baffle is provided on the outer wall of one side of the linkage plate through a bracket. The baffle is provided to shield and protect the controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the control device for photovoltaic power generation not only ensures the stability of the control device during use, but also allows the control device to be operated from different directions, thereby improving the convenience of using the control device. In addition, it reduces the phenomenon of personnel accidentally touching the controller and causing misoperation of the control device, and can reduce the phenomenon of damage to the controller.

[0012] By installing the diagonal bracing legs onto the outer wall of the base frame using positioning pins, the diagonal bracing legs, together with the base frame, can support and house the control box and other related components, thereby ensuring the stability of the control device during use.

[0013] The rack is driven to translate by the telescopic drive component, which in turn drives the gear to rotate. The gear drives the disc to rotate synchronously via the rotating shaft, thereby horizontally adjusting the angle of the control box. This allows the control device to be operated from different directions, improving the convenience of using the control device.

[0014] The rotary drive component drives the lead screw to rotate, causing the linkage plate located on the outer wall of the lead screw and guide rod to slide downwards. This causes the linkage plate to move the baffle down to the front of the controller, thus shielding and protecting the controller. This reduces the possibility of accidental contact with the controller, which could lead to malfunctions and damage to the controller. Attached Figure Description
