Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell installation technology, and in particular to a photovoltaic cell support bracket. Background Technology

[0002] With the continuous development of new energy technologies and the national strategic requirements for new energy, the scale of photovoltaic power generation is also increasing. The power generation efficiency of photovoltaic panels is related to the angle of direct sunlight, and the tilt angle of photovoltaic panels needs to be adjusted to adapt to direct sunlight in different seasons.

[0003] Currently, adjusting the tilt angle of photovoltaic (PV) panels mainly involves adjusting the support brackets. Taking PV panels installed on a hillside as an example, they are typically supported by a single tube. For single-tube supports, a common method is to install an arc-shaped plate under the support plate, with fixing holes drilled around the edge of the arc-shaped plate. The tilt angle of the PV panel is adjusted by changing the fixing holes used to tighten the bolts to the single tube. This results in cumbersome adjustments, requiring repeated testing and adjustments to the tightening of the single tube bolts, which is inconvenient for PV panel installation. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing technology involves setting an arc plate under a support plate and opening fixing holes on the circumference of the edge of the arc plate. The adjustment of the tilt angle of the photovoltaic panel is achieved by changing the fixing holes that are fastened to the single pipe bolts. However, the adjustment process is cumbersome. Therefore, a photovoltaic panel support is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A photovoltaic cell support is designed, including a base, a connecting frame at the top of the base, a lifting component at the bottom of the connecting frame, the lifting component being connected to the top of the base, support rods connected to both sides of the top of the connecting frame via bearings, a fixing frame between the tops of the two support rods, a photovoltaic cell panel being mounted on the fixing frame, and an adjustment mechanism between the two support rods, the adjustment mechanism being connected to the connecting frame to adjust the two support rods relative to the connecting frame; The adjustment mechanism includes sliding grooves formed on two support rods, a sliding rod disposed between the two sliding grooves, and a clamping block disposed at both ends of the sliding rod. When one of them is in working state, its clamping block presses against the connecting frame. A threaded rod is threadedly connected to the sliding rod, and one end of the threaded rod is connected to the bottom of the fixed frame through a bearing.

[0006] Preferably, the bottom of the clamping block is provided with a protruding clip, and the connecting frame is provided with a semi-toothed ring, which cooperates with the protruding clip.

[0007] Preferably, the side of the protruding clip that contacts the semi-toothed ring is provided with a nitrided hardening layer.

[0008] Preferably, the lifting assembly includes two movable seats slidably disposed at the bottom of the connecting frame. Each of the two movable seats has a connecting rod hinged to its bottom. One end of each of the two connecting rods is hinged to the base. A driving mechanism is provided on one side of the connecting frame. The driving mechanism is connected to the two movable seats, causing the two movable seats to move towards each other to adjust the distance between the two movable seats.

[0009] Preferably, the two movable seats are arranged symmetrically around the connecting frame.

[0010] Preferably, both the threaded rod and the sliding rod have a wear-resistant coating on their working surfaces.

[0011] The photovoltaic cell support proposed in this utility model has the following advantages: 1. After the angle of the fixed frame relative to the connecting frame is changed, the fixed frame can better adjust the angle of the photovoltaic panel, thereby improving the light-gathering effect of the photovoltaic panel. The sliding rod is driven by the threaded rod to move in the slide groove. During the movement of the sliding rod, the clamping blocks at both ends will move together, so that the two clamping blocks can press the connecting frame tightly. This achieves mechanical locking of the clamping blocks, sliding rod, threaded rod, and fixed frame relative to the connecting frame, and at the same time, the device is stable.

[0012] 2. By driving the two movable seats through the drive mechanism, the distance between the two movable seats is adjusted, and the connecting rod at the bottom of the two movable seats will be in a rotating state, thereby adjusting the height of the connecting frame relative to the base, and thus adjusting the height of the components at the top of the connecting frame, so as to facilitate the uniform adjustment of photovoltaic panels of different heights.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3 A photovoltaic cell support includes a base 1, a connecting frame 2 at the top of the base 1, a lifting assembly at the bottom of the connecting frame 2, the lifting assembly being connected above the base 1, support rods 3 connected to both sides of the top of the connecting frame 2 via bearings, a fixing frame 4 between the tops of the two support rods 3, a photovoltaic cell panel 5 mounted on the fixing frame 4, and an adjustment mechanism between the two support rods 3 connected to the connecting frame 2 to adjust the two support rods 3 relative to the connecting frame 2. The adjustment mechanism includes a sliding groove 6 formed on the two support rods 3, a sliding rod 7 between the two sliding grooves 6, and a clamping block 8 at both ends of the sliding rod 7. In the working state, the clamping block 8 of one of the sliding rods 7 is pressed against the connecting frame 2. A threaded rod 9 is threadedly connected to the sliding rod 7, and one end of the threaded rod 9 is connected to the bottom of the fixing frame 4 via a bearing.

[0019] Usage: Use a tool to rotate the threaded rod 9. The threaded rod 9 drives the sliding rod 7 to move within the groove 6. During the movement of the sliding rod 7, it will move along with the clamping blocks 8 at both ends, so that the two clamping blocks 8 can clamp the connecting frame 2. This allows the clamping blocks 8, sliding rod 7, threaded rod 9, and fixing frame 4 to achieve mechanical locking relative to the connecting frame 2. After the angle of the fixing frame 4 relative to the connecting frame 2 changes, the fixing frame 4 can better adjust the angle of the photovoltaic panel 5, thereby improving the light-gathering effect of the photovoltaic panel 5 and simplifying the installation process of the photovoltaic panel 5.

[0020] Example 2: In Example 1, the clamping block 8 and the connecting frame 2 have a sliding compression fit. When the contact between them is not tight, and the clamping block 8 is in an inclined state, the weight of the photovoltaic panel 5 and the fixing frame 4 will cause the clamping block 8 and the connecting frame 2 to slip, thus creating a hazard. An optimization is made based on Example 1, referencing... Figure 1-3 The bottom of the clamping block 8 is provided with a protruding clip 10, and the connecting frame 2 is provided with a half toothed ring 11. The half toothed ring 11 cooperates with the protruding clip 10. The side of the protruding clip 10 that contacts the half toothed ring 11 is provided with a nitriding hardening layer. The nitriding hardening layer improves the mechanical strength of the protruding clip 10 and the half toothed ring 11, thereby avoiding the probability of accidents during the cooperation of the protruding clip 10 and the half toothed ring 11, and thus improving the safety of the device.

[0021] Example 3: In Example 1, the height of the photovoltaic panel 5 is difficult to adjust, making it challenging to uniformly adjust the photovoltaic panels 5 in the same area. Based on Example 1, optimizations are made, referring to... Figure 1-3 The lifting assembly includes two movable seats 12 that are slidably disposed at the bottom of the connecting frame 2. Each of the two movable seats 12 has a connecting rod 13 hinged to its bottom. One end of each of the two connecting rods 13 is hinged to the base 1. A drive mechanism 14 is provided on one side of the connecting frame 12. The drive mechanism is connected to the two movable seats 12, so that the two movable seats 12 move toward each other to adjust the distance between the two movable seats 12.

[0022] Usage process: The two movable seats 12 are driven by the drive mechanism 14. After the distance between the two movable seats 12 is adjusted, the connecting rods 13 at the bottom of the two movable seats 12 will be in a rotating state. Both connecting rods 13 are located at one end of the base 1 and also rotate, thereby adjusting the height of the connecting frame 2 relative to the base 1, thereby adjusting the height of the components at the top of the connecting frame 2, so as to facilitate the uniform adjustment of photovoltaic panels 5 of different heights.

[0023] Example 4: An optimization based on Examples 1-3, with reference to... Figure 1-3 The two movable seats 12 are symmetrically arranged around the connecting frame 2, so that the connecting rod 13 at the bottom of the two movable seats 12 is subjected to more even force, thereby increasing the stability of the device. The working surfaces of the threaded rod 9 and the sliding rod 7 are both provided with wear-resistant coatings. The wear-resistant coatings are formed by arc spraying ceramic particles, which improves the wear resistance of the threaded rod 9 and the sliding rod 7, thereby increasing the service life of the device.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
