Description

Technical Field

[0001] This utility model belongs to the technical field of distributed photovoltaic group control devices, and in particular relates to an installation structure for distributed photovoltaic group control devices. Background Technology

[0002] With the global energy structure shifting towards cleaner and lower-carbon energy, the distributed photovoltaic industry is experiencing explosive growth. Its flexible layout and decentralized power generation characteristics have become an important support for achieving the "dual carbon" goal. In distributed photovoltaic systems, the group control device, as the core control unit, plays a crucial role in coordinating the power output of multiple photovoltaic modules, optimizing energy dispatch, and ensuring the stable operation of the system. Its installation stability and adaptability directly affect the operating efficiency and service life of the entire photovoltaic system. Therefore, an efficient and reliable installation structure is needed to fix and protect the group control device.

[0003] However, the existing installation structure is cumbersome to install, requiring more manpower and effort to complete complex operations, increasing labor costs, significantly reducing overall installation efficiency, and affecting the convenience and timeliness of maintenance work. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for a distributed photovoltaic group control device. By setting up an installation section, it solves the problems of existing installation structures, which are cumbersome to install, require more manpower and effort to complete complex operations, increase labor costs, significantly reduce overall installation efficiency, and affect the convenience and timeliness of maintenance operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model discloses an installation structure for a distributed photovoltaic group control device, comprising an assembly box and several rectangular rings disposed within the assembly box, each of the rectangular rings being equipped with a distributed photovoltaic group control device. It further includes: several mounting parts mounted on the rectangular rings; several anti-reversal parts mounted on the mounting parts; each mounting part including a drive assembly mounted on the rectangular rings; and a fixing assembly mounted on the drive assembly. The drive assembly includes a T-shaped support plate fixedly connected within the rectangular rings. Two rectangular plates are fixedly connected to the bottom of the T-shaped support plate. A trapezoidal groove is formed at the bottom of the T-shaped support plate. A threaded rod is rotatably connected between the two rectangular plates. The front side of the threaded rod passes through the rectangular plate on the front side and extends outward. A handle is fixedly connected to the outer wall of the threaded rod. A transmission component is provided on the threaded rod. The handle is located below the front side of the T-shaped support plate. The transmission component includes a drive block threadedly connected to the outer wall of the threaded rod. The top of the drive block extends into the trapezoidal groove. The drive block is slidably connected to the trapezoidal groove. Two drive rods are hinged on the drive block. The two drive rods are located on the left and right sides of the drive block and are arranged in a mirror image.

[0006] Furthermore, the anti-reverse component includes a friction assembly mounted on a rectangular plate located on the front side; an adjustment assembly mounted on the friction assembly; and the adjustment assembly located inside the friction assembly.

[0007] Furthermore, the fixing component includes two limiting grooves formed on the T-shaped support plate, each limiting groove having a slider slidably connected therein. Each slider has an L-shaped fixing plate fixedly connected to its top, and anti-slip buffer pads fixedly connected to the sides of the two L-shaped fixing plates that are close to each other. Connectors are provided at the bottom of each slider. The two L-shaped fixing plates are located on both sides of the distributed photovoltaic group control device. The connectors include cylindrical connecting rods fixedly connected to the bottom of each slider, and the two cylindrical connecting rods are slidably connected to two drive rods. The two cylindrical connecting rods are arranged in a mirror image.

[0008] Furthermore, the friction assembly includes a friction ring fixedly connected to the outer wall of the threaded rod. A hollow rectangular block is fixedly connected to the front side of the rectangular plate located at the front. Two rectangular limiting plates are disposed inside the hollow rectangular block, and both rectangular limiting plates are slidably connected to the inner wall of the hollow rectangular block. A support protrusion is fixedly connected to the right side of the rectangular limiting plate located on the right side. The right side of the support protrusion penetrates through the hollow rectangular block and extends outward. A silicone pad is fixedly connected to the right side of the support protrusion. The right side of the silicone pad contacts the outer wall of the friction ring. An elastic element is disposed inside the hollow rectangular block. The hollow rectangular block is located on the left side of the friction ring. The elastic element includes a spring disposed inside the hollow rectangular block. The left side of the spring is fixedly connected to the rectangular limiting plate located on the left side, and the right side of the spring is fixedly connected to the rectangular limiting plate located on the right side. The spring is located between the two rectangular limiting plates.

[0009] Furthermore, the adjustment assembly includes a rotating rod rotatably connected to the inner rear wall of the hollow rectangular block, the front side of the rotating rod extending to the outside of the hollow rectangular block, a cam fixedly connected to the outer wall of the rotating rod, and a handle fixedly connected to the outer wall of the rotating rod; the cam is located inside the hollow rectangular block and to the left of the rectangular limiting plate, and the handle is located at the front of the hollow rectangular block.

[0010] Furthermore, the distributed photovoltaic group control device in this device adopts the Hangtu Technology iHT-E130-Z3-AGVC distributed photovoltaic group control device. Its working principle is as follows: by directly collecting data from the power generation equipment and measurement and control devices, or obtaining data from remote motors and data acquisition devices, the data is transmitted to the dispatch master station wirelessly and with vertical encryption. At the same time, it receives instructions issued by the dispatch master station, uses the AGC function to optimize the active power distribution of the inverter, the AVC function to reasonably allocate reactive power to stabilize the voltage, and automatically adjusts the active power output through primary frequency regulation based on the preset frequency dead zone range, thereby realizing the group control of the distributed photovoltaic power generation system.

[0011] This utility model has the following beneficial effects: 1. By setting up the installation section, first place the distributed photovoltaic group control device on the rectangular ring between two L-shaped fixing plates. Then, turn the handle to rotate the threaded rod, which will drive the drive block to slide smoothly in the trapezoidal groove. The drive block, through the connection between the drive rod and the cylindrical connecting rod, drives the two sliders to move closer to each other in the limiting groove, thereby bringing the anti-slip buffer pads on the two L-shaped fixing plates closer together, thus fixing the device. The fixing can be released by reversing the steps. No complicated tools or cumbersome steps are required, which reduces the difficulty of operation, saves time costs during installation and maintenance, and facilitates the staff to quickly carry out related work. 2. By setting up an anti-reverse rotation mechanism, after the distributed photovoltaic group control device is installed, turning the handle drives the rotating rod to rotate, which in turn drives the cam to rotate. The rotating cam will press against the left rectangular limit plate. The left rectangular limit plate pushes the right rectangular limit plate to move through the spring, which in turn drives the support protrusion and silicone pad to move closer to the friction ring. At the same time, the cam compresses the spring to generate elastic force. With the cooperation of the silicone pad and the friction ring, the rotation of the threaded rod is restricted. With the help of the straight edges on both sides of the cam and the elastic force of the spring, the cam is placed horizontally between the hollow rectangular block and the left rectangular limit plate, which further increases the friction between the silicone pad and the friction ring. This prevents the device from becoming loose due to accidental rotation of the threaded rod after it is fixed, ensuring the stability of the device after installation. It also makes it easier for staff to quickly complete the locking operation and improves work efficiency.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] A specific application of this embodiment is as follows: In use, the distributed photovoltaic group control device 113 is placed on the rectangular ring 112 and positioned between two L-shaped fixing plates 223. Then, the threaded rod 214 is rotated by the handle 215. At this time, the threaded rod 214 drives the drive block 216 to slide on the trapezoidal slide groove 213. Under the parallel design of the threaded rod 214 and the trapezoidal slide groove 213, the drive block 216 moves smoothly.

After installation, the lever 321 is rotated by the throttle 323. At this time, the lever 321 drives the cam 322 to rotate. The cam 322 then presses against the rectangular limiting plate 313 on the left. The rectangular limiting plate 313 on the left pushes the rectangular limiting plate 313 on the right to move through the spring 316. This causes the supporting protrusion 314 and the silicone pad 315 to move closer to the friction ring 311. Under the action of the cam 322, the spring 316 is compressed, generating elastic force. Under the action of the silicone pad 315 and the friction ring 311, the rotation of the threaded rod 214 is restricted. Under the action of the straight edges on both sides of the cam 322 and the elastic force of the spring 316, the cam 322 is positioned horizontally between the hollow rectangular block 312 and the rectangular limiting plate 313 on the left, thereby increasing the friction between the silicone pad 315 and the friction ring 311. Through the same operation process as described above, several mounting parts 2 and anti-reverse parts 3 are driven to fix several distributed photovoltaic group control devices 113.
