Description
Technical Field
[0001] This utility model relates to the technical field of support structure for photovoltaic modules, and in particular to a wind-resistant support structure for outdoor photovoltaic inverters. Background Technology
[0002] The direct current generated by photovoltaic modules needs to be converted into alternating current. Chinese utility model patent, authorized announcement number "CN221487607U", discloses a wind-resistant support structure for photovoltaic inverters. When the photovoltaic inverter is subjected to strong lateral winds on the mounting bracket, and it is about to deflect on the photovoltaic column based on U-bolts, it is fixed by the bottom support rod and the through bolt to resist the lateral deflection torque. At the same time, the bottom support rod transfers part of the weight of the mounting bracket and the photovoltaic inverter as a whole to the through bolt for reinforced support, so that the mounting bracket and the photovoltaic inverter as a whole will not be displaced by gravitational inertia. This solves the problem that the existing technology has poor wind resistance when subjected to strong lateral winds and the U-bolt is based on the column, resulting in downward displacement due to gravity inertia.
[0003] The above-mentioned technical solutions, which use only simple fixed supports, cannot effectively disperse wind force when facing strong winds from different directions. This leads to excessive wind pressure on the inverter in certain areas, making it prone to structural damage. When the wind direction is perpendicular to the fixed direction of the support, the support cannot provide sufficient lateral support, causing the inverter to sway under prolonged wind force. Under such conditions, the inverter may loosen due to frequent vibration, thus shortening the service life of the equipment. Therefore, we propose a wind-resistant support structure for outdoor photovoltaic inverters. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a wind-resistant support structure for outdoor photovoltaic inverters. This structure can solve the problem that when using only a simple fixed bracket, the inverter cannot effectively disperse the wind force when facing strong winds from different directions, resulting in excessive wind pressure on certain parts of the inverter and making it prone to structural damage. When the wind direction is perpendicular to the fixed direction of the bracket, the bracket cannot provide sufficient lateral support force, causing the inverter to sway under the action of wind force for a long time. Under such conditions for a long time, the inverter may loosen due to frequent vibration, thereby shortening the service life of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant support structure for an outdoor photovoltaic inverter, comprising: The mounting box has a photovoltaic inverter installed on its top. Wind-dispersing structure, located on the mounting box; The wind-dispersing structure includes a mounting frame, a grid top cover, an regulating box, a rotating shaft, a rotating disk, a support plate, and a wind-resistant curved plate. The mounting frame is fixedly connected to the top of the mounting box, and the photovoltaic inverter is placed inside the mounting frame. The grid top cover is bolted to the top of the mounting frame, the regulating box is fixedly connected to the top of the grid top cover, the rotating shaft is rotatably connected to the inside of the regulating box, and the top end of the rotating shaft rotates through the top of the regulating box and is fixedly connected to the rotating disk. The support plate is fixedly connected to the outer surface of the rotating disk, and the wind-resistant curved plate is fixedly connected to the side of the support plate away from the rotating disk.
[0006] Preferably, the wind power dispersion structure further includes a stepper motor, a gear, and a gear ring. The gear ring is fixedly sleeved on the outer surface of the rotating shaft, the stepper motor is fixedly installed inside the regulating box, the output end of the stepper motor is fixedly connected to the gear, and the gear meshes with the gear ring.
[0007] Preferably, a support column is fixedly installed at the bottom of the mounting box, and a fixed base plate is fixedly connected to the bottom end of the support column.
[0008] Preferably, the mounting box has a door hinged to one side.
[0009] Preferably, the photovoltaic panel is fixedly installed on the side of the mounting box away from the box door.
[0010] Preferably, a storage battery is installed inside the mounting box, and a charging controller is fixedly installed on one side of the storage battery.

[0012] Preferably, the bottom of the mounting box has multiple heat dissipation holes that communicate with its interior.
[0013] Preferably, the bottom of the grille cover contacts the top of the photovoltaic inverter.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The wind-resistant support structure of this outdoor photovoltaic inverter, through the cooperation of gears, gear rings, rotating shafts, rotating disks, support plates, and wind-resistant arc plates, ensures that the convex surface of the wind-resistant arc plate accurately faces the wind direction. This allows the wind-resistant arc plate to be adjusted according to different wind directions. The arc structure of the wind-resistant arc plate can disperse some of the wind force along the arc surface, reducing the wind force directly acting on the photovoltaic inverter and mounting box. This avoids the situation where, like traditional fixed brackets, the wind force cannot be effectively dispersed when the wind direction is perpendicular to the fixed direction of the bracket, resulting in excessive wind pressure on the inverter and easy structural damage. This protects the structural safety of the equipment. Attached Figure Description

[0021] Please see Figure 1-4 This utility model provides a technical solution: a wind-resistant support structure for an outdoor photovoltaic inverter, comprising: Mounting box 3, with a photovoltaic inverter 8 installed on the top of mounting box 3; The wind-dispersing structure is located on the mounting box 3; The wind-dispersing structure includes a mounting frame 9, a grid top cover 16, an regulating box 13, a rotating shaft 14, a rotating disk 6, a support plate 12, and a wind-resistant arc plate 7. The mounting frame 9 is fixedly connected to the top of the mounting box 3. The photovoltaic inverter 8 is placed inside the mounting frame 9. The grid top cover 16 is bolted to the top of the mounting frame 9. The bottom of the grid top cover 16 contacts the top of the photovoltaic inverter 8. The regulating box 13 is fixedly connected to the top of the grid top cover 16. The rotating shaft 14 is rotatably connected to the inside of the regulating box 13. The top end of the rotating shaft 14 rotates through the top of the regulating box 13 and is fixedly connected to the rotating disk 6. The support plate 12 is fixedly connected to the outer surface of the rotating disk 6. The wind-resistant arc plate 7 is fixedly connected to the side of the support plate 12 away from the rotating disk 6.
[0022] The wind power distribution structure also includes a stepper motor 18, a gear 19, and a gear ring 17. The gear ring 17 is fixedly sleeved on the outer surface of the rotating shaft 14. The stepper motor 18 is fixedly installed inside the regulating box 13. The output end of the stepper motor 18 is fixedly connected to the gear 19, and the gear 19 meshes with the gear ring 17.
[0023] A support column 2 is fixedly installed at the bottom of the mounting box 3. A fixed base plate 1 is fixedly connected to the bottom end of the support column 2. A door 4 is hinged to one side of the mounting box 3. A photovoltaic panel 5 is fixedly installed on the side of the mounting box 3 away from the door 4. A storage battery 10 is installed inside the mounting box 3. A charging controller 11 is fixedly installed on one side of the storage battery 10. Multiple through holes 15 are opened on the outer surface of the regulating box 13. Multiple heat dissipation holes communicating with the interior are opened at the bottom of the mounting box 3.
[0024] Furthermore, when using the device, during the day when there is sunlight, the photovoltaic panel 5 absorbs solar energy and converts it into direct current. The direct current is transmitted through the line to the charging controller 11 inside the mounting box 3. After the charging controller 11 regulates and controls the current and voltage, it stores the electrical energy in the battery 10 for later use. The photovoltaic inverter 8 is placed inside the mounting frame 9, and the grid top cover 16 is bolted to the top of the mounting frame 9, which facilitates the protection of the photovoltaic inverter 8.
[0025] When strong winds occur outdoors, wind direction information is obtained through weather forecasts. Based on the wind direction information, stepper motor 18 is started, which drives gear 19 to rotate. Since gear 19 is meshed with gear ring 17, the rotation of gear 19 will drive gear ring 17 to rotate, which in turn causes rotating shaft 14 to rotate inside regulating box 13. Rotating shaft 14 drives rotating disk 6 to rotate. Rotating disk 6 drives wind-resistant arc plate 7 to rotate through support plate 12, so that the concave surface of wind-resistant arc plate 7 faces the wind direction to better disperse and withstand wind force. The arc design of wind-resistant arc plate 7 can change the direction of airflow, so that some wind force is dispersed along the arc surface, reducing the wind force directly acting on photovoltaic inverter 8 and mounting box 3. At the same time, since rotating disk 6 is located on top of regulating box 13, rainwater is prevented from directly hitting photovoltaic inverter 8.
[0026] The bottom of the mounting box 3 is fixedly equipped with a support column 2, and the bottom end of the support column 2 is fixedly connected to a fixed base plate 1. The fixed base plate 1 is fixed to the ground by bolts or other means, providing stable support for the entire structure and ensuring that the mounting box 3 and the photovoltaic inverter 8 will not tip over under strong winds.
[0027] Through the cooperation of gear 19, gear ring 17, rotating shaft 14, rotating disk 6, support plate 12 and wind-resistant arc plate 7, the convex surface of wind-resistant arc plate 7 is accurately oriented towards the wind direction, allowing wind-resistant arc plate 7 to be adjusted according to different wind directions. The arc structure of wind-resistant arc plate 7 can disperse some wind force along the arc surface, reducing the wind force directly acting on photovoltaic inverter 8 and mounting box 3. This avoids the situation where, like traditional fixed brackets, the wind force cannot be effectively dispersed when the wind direction is perpendicular to the fixed direction of the bracket, resulting in the inverter being subjected to excessive wind pressure locally, which can easily lead to structural damage. This protects the structural safety of the equipment.
