Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically a photovoltaic installation tilt angle rapid calibration device. Background Technology

[0002] Photovoltaic equipment mainly refers to machinery and equipment used to produce photovoltaic-related products such as raw materials, battery modules, and components. When installing photovoltaic equipment, it is usually necessary to consider the optimal angle for the photovoltaic panels to receive sunlight. The installation tilt angle of the photovoltaic panels needs to be detected and calibrated. However, existing technology requires the use of engineering protractors when adjusting the installation tilt angle. However, these protractors are large in size, inconvenient to use, and prone to deviations. They need to be adjusted multiple times and cannot be assembled with the photovoltaic mounting bracket.

[0003] For example, the intelligent photovoltaic installation tilt angle calibration device described in patent CN223122223U includes a base plate, a protractor rotatably connected to the top of the base plate, a groove on the bottom of the base plate, and an indicator rod rotatably connected to the inner wall of the groove. The base plate, protractor, and indicator rod are rotatably connected via a suction cup. By using the protractor and indicator rod together, it is convenient to detect the tilt angle of the photovoltaic equipment's mounting base and main body, thereby facilitating the determination of the photovoltaic equipment's installation tilt angle and improving the device's practicality. However, when adjusting the photovoltaic mounting bracket, it only uses the suction cup to attach the device to the photovoltaic equipment's base without restricting it. This may cause the calibration device to tilt during subsequent adjustments, resulting in deviations in angle measurement and reducing the device's practicality.

[0004] Based on this, a rapid calibration device for photovoltaic installation tilt angle is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a rapid calibration device for photovoltaic installation tilt angle to solve the problems in the background art.

A lever is fixedly connected to the outer wall of the rotating rod. A torsion spring is fixedly connected to the side wall of the lever. One end of the torsion spring is fixedly connected to the inside of the mounting frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model achieves the effect of quickly calibrating the installation tilt angle by using an angle ruler, a rotating shaft, a pointer, a positioning component, and a limiting component. By removing the restriction of the rotating shaft by the positioning component and restricting the positioning component by the limiting component, the tilt angle of the photovoltaic mounting bracket can then be adjusted and calibrated. During the adjustment and calibration process, the current tilt angle is determined by the pointer pointing to the scale of the angle ruler, thereby determining the tilt angle of the photovoltaic mounting bracket.

[0019] 2. This utility model achieves the effect of avoiding deviation during the calibration of the tilt angle by using a fixed rod, a movable rod, a fixing bolt, and a photovoltaic mounting bracket. The fixing bolt fixes the fixed rod and the movable rod to the photovoltaic mounting bracket respectively, preventing the fixed rod from shifting when adjusting the included angle of the photovoltaic mounting bracket later.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, the photovoltaic installation tilt angle rapid calibration device includes a fixed rod 1, a rotating shaft 15 is rotatably connected inside the fixed rod 1, a movable rod 11 is fixedly connected to the outer wall of the rotating shaft 15, both the fixed rod 1 and the movable rod 11 have through holes on their outer walls, and fixing bolts 12 are installed in the through holes. A photovoltaic installation bracket 13 is installed on the side wall of the fixed rod 1. The fixed rod 1 and the movable rod 11 are detachably connected to the photovoltaic installation bracket 13 by the fixing bolts 12. A positioning component 2 is installed on the side wall of the fixed rod 1, and a limit component 3 is installed on the side wall of the fixed rod 1 away from the positioning component 2.

[0027] The positioning component 2 includes a mounting frame 21, which is fixedly connected to the side wall of the fixing rod 1. A rotating rod 22 is rotatably connected inside the mounting frame 21. A lever 23 is fixedly connected to the outer wall of the rotating rod 22. A torsion spring 24 is fixedly connected to the side wall of the lever 23. One end of the torsion spring 24 is fixedly connected to the inside of the mounting frame 21.

[0028] In this embodiment, the fixed rod 1, the movable rod 11 and the photovoltaic mounting bracket 13 are fixed by the fixing bolt 12, so as to facilitate the subsequent adjustment of the included angle of the photovoltaic mounting bracket 13. During the subsequent adjustment process, the restriction on the rotating shaft 15 can be released by the cooperation of the positioning component 2 and the limiting component 3, and the included angle of the photovoltaic mounting bracket 13 can be adjusted.

[0029] In an optional embodiment, such as Figure 3 As shown, an angle ruler 14 is fixedly connected to the side wall of the fixed rod 1. The through hole on the angle ruler 14 is rotatably connected to the rotating shaft 15. A pointer 16 is fixedly connected to the outer wall of the rotating shaft 15. The pointer 16 is aligned with the scale on the angle ruler 14. By rotating the photovoltaic mounting bracket 13, the movable rod 11 is driven to rotate synchronously. The movable rod 11 drives the rotating shaft 15 and the pointer 16 to rotate. The angle of the photovoltaic mounting bracket 13 is determined by the scale pointed to by the pointer 16, and then the installation tilt angle of the photovoltaic panel is determined.

[0030] In an optional embodiment, such as Figure 3 As shown, a retaining block 25 is fixedly connected to the top of the lever 23. The outer wall of the retaining block 25 fits against the outer wall of the rotating shaft 15, and the shape of the retaining block 25 is arc-shaped, which matches the curved surface of the rotating shaft 15. This allows the retaining block 25 to fit tightly against the rotating shaft 15, avoiding deviations that would prevent the subsequent locking block 26 from connecting with the locking slot.

[0031] In an optional embodiment, such as Figure 3 As shown, a locking block 26 is fixedly connected to the outer wall of the clamping block 25. The locking block 26 is inserted into a slot on the rotating shaft 15, and the slot is compatible with the shape of the locking block 26. The locking block 26 is made of rubber with a Shore hardness of 60±5HA and a compression set of ≤15%. The clamping block 25 contacts the outer wall of the rotating shaft 15, and the rubber locking block 26 forms an interference fit with the slot under the preload of the torsion spring 24. This creates a large frictional resistance between the locking block 26 and the slot, preventing the rotating shaft 15 from rotating easily.

[0032] In an optional embodiment, such as Figure 4As shown, the limiting component 3 includes a fixed frame 31. One end of the fixed frame 31 is fixedly connected to the side wall of the fixed rod 1. A spring 32 is fixedly connected inside the fixed frame 31. A limiting block 33 is fixedly connected to the end of the spring 32. The limiting block 33 is slidably connected to a groove opened on the fixed frame 31. The limiting block 33 has a chamfer on the outer wall near the lever 23. When the lever 23 is rotated, the lever 23 contacts the inclined surface of the limiting block 33, squeezing the limiting block 33 and causing it to slide into the fixed frame 31, thus compressing the spring 32. When the lever 23 is rotated downward to a certain position, it no longer blocks the limiting block 33. At this time, under the action of the spring 32, the limiting block 33 slides out from the inside of the fixed frame 31 and blocks the lever 23, preventing it from rotating upward.

[0033] In an optional embodiment, such as Figure 4 As shown, a lever 34 is fixedly connected to the bottom end of the limiting block 33. The lever 34 is slidably connected to the groove opened on the fixed frame 31. By moving the lever 34, the spring 32 is compressed, causing the limiting block 33 to slide into the fixed frame 31, thereby removing the restriction on the lever 23. Then, under the action of the torsion spring 24, the lever 23 returns to its original position, and the abutment block 25 is attached to the outer wall of the rotating shaft 15. The locking block 26 is engaged with the locking groove opened on the rotating shaft 15, thereby restricting the rotating shaft 15 and preventing it from rotating.

[0034] The above embodiment discloses a rapid photovoltaic installation tilt angle calibration device. During photovoltaic panel installation, the fixed rod 1 and movable rod 11 are respectively fixed to the photovoltaic mounting bracket 13 using fixing bolts 12. This prevents the fixed rod 1 from shifting when adjusting the included angle of the photovoltaic mounting bracket 13. Then, the lever 23 is moved downwards, releasing the restraining block 25 and the locking block 26 from the rotating shaft 15. Simultaneously, the rotating rod 22 rotates, causing the torsion spring 24 to deform. At the same time, the lever 23 contacts the inclined surface of the limiting block 33, pressing the limiting block 33 and causing it to slide inwards into the fixed frame 31, compressing the spring 32. When the lever 23 rotates downwards to a certain position, it no longer obstructs the limiting block 33. At this point, under the action of the spring 32, the limiting block 33 slides out from inside the fixed frame 31 and blocks the lever 23, preventing it from rotating upwards. Then, the photovoltaic mounting bracket 13 can be rotated, causing the movable rod 11 to rotate synchronously. 11 drives the rotating shaft 15 and pointer 16 to rotate. The angle of the photovoltaic mounting bracket 13 is determined by the scale indicated by pointer 16, and then the installation tilt angle of the photovoltaic panel is determined. After the angle is determined, the lever 34 is moved to compress the spring 32 and make the limiting block 33 slide into the fixed frame 31, thereby removing the restriction on the lever 23. Then, under the action of the torsion spring 24, the lever 23 returns to its original position and the abutting block 25 is attached to the outer wall of the rotating shaft 15. The locking block 26 engages with the slot opened on the rotating shaft 15, thereby restricting the rotating shaft 15 and preventing it from rotating. In summary, the fixed rod 1, the movable rod 11 and the photovoltaic mounting bracket 13 are fixed by the fixing bolt 12, which facilitates the subsequent adjustment of the angle of the photovoltaic mounting bracket 13. During the subsequent adjustment process, the restriction on the rotating shaft 15 can be released by the cooperation of the positioning component 2 and the limiting component 3, and the angle of the photovoltaic mounting bracket 13 can be adjusted.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
