Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, in particular to a solar panel mounting frame for photovoltaic engineering. Background Art

[0002] In the context of the global shortage of non-renewable resources, building photovoltaic projects and using light energy to produce energy has become an important development method. Solar power generation generally uses mounting frames to support solar panels. There are various solar panel mounting frames for photovoltaic projects on the market, but there are still some shortcomings. For example, when solar panels are installed in remote areas such as jungles and grasslands, the weeds and shrubs outside the mounting frame are easily blocked by the solar panels, which cannot ensure that the solar panels can fully receive solar energy, thus affecting the conversion efficiency of solar power generation. It is time-consuming and laborious to manually arrive at the site to clean the weeds outside, which is very inconvenient. For example, the solar panels cannot adjust the angle of the solar panels according to the changes in the direct sunlight point in the four seasons, so that the solar panels cannot form the best light receiving angle, thereby reducing the light energy conversion rate.

[0003] The Chinese patent published with announcement number: CN218387352U is specifically a solar panel mounting frame for photovoltaic engineering with a cleaning function, including a mounting frame body, a driving motor, a supporting frame, a main fixing frame, a secondary fixing frame, a driving motor, a first adjusting rod, etc. The main blade and the secondary blade cut and clean the weeds on the outside of the mounting frame from three sides respectively, and the main blade and the secondary blade are driven to move horizontally by the driving motor and the first adjusting rod to prevent the weeds from blocking the solar panel and affecting the conversion efficiency of solar power generation.

[0004] However, the patent may have the following defects: using blades to cut weeds may cause wear and broken teeth during long-term use, resulting in a decrease in cutting force. In addition, the blades are exposed to the external environment for a long time, which is dangerous and can easily injure people and animals nearby. Each blade requires a motor to rotate and also requires a motor to move, which is not only complex in structure but also has high power costs. At the same time, the solar panels in the patent are fixed and cannot adjust the angle with the light, resulting in the inability to achieve the optimal conversion rate of light energy.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to solve the problems of unstable cutting force, low safety, complex structure, high power cost and inability to adjust the angle of solar panels in the prior art, the following technical solutions are provided. Please refer to Figure 1-5 ;

[0028] A solar panel mounting frame for photovoltaic engineering includes a bracket 1, a solar panel 2 is arranged above the bracket 1, one side of the solar panel 2 is hinged to the bracket 1, and the other side of the solar panel 2 is connected to the bracket 1 through an angle adjustment component 3. The bracket 1 includes a horizontal frame 11 and supporting legs 12 respectively arranged at four corners of the horizontal frame 11, a motor 4 is arranged below the horizontal frame 11, a flexible cutting device 5 is arranged on the supporting legs 12, and the flexible cutting device 5 is connected to the motor 4 through a transmission component 6.

[0029] The angle adjustment assembly 3 includes a telescopic rod 31 and a pivot 32 . A telescopic rod 31 is installed at each of the two corners of the opening and closing side of the solar panel 2 . The upper and lower ends of the telescopic rod 31 are respectively connected to the solar panel 2 and the horizontal frame 11 through the pivot 32 .

[0030] Specifically, by adjusting the length of the telescopic rod 31, one side of the solar panel 2 can be adjusted to a suitable height and fixed at this angle, so that the receiving surface of the solar panel 2 can be maintained at the optimal light energy conversion angle with the sunlight, thereby improving the light energy conversion rate; here, the telescopic rod 31 can adopt a manual adjustment rod, or the telescopic function can be realized by a hydraulic rod or a pneumatic rod.

[0031] The flexible cutting device 5 includes a rotating cylinder 51 and a cutting rope 52. A plurality of protruding rings 511 are provided on the inner wall of the rotating cylinder 51. A concave ring 121 matching the protruding ring 511 is correspondingly provided at the upper portion of the supporting foot 12. The rotating cylinder 51 is sleeved outside the supporting foot 12, and the protruding ring 511 is engaged in the concave ring 121 and can slide in the concave ring 121.

[0032] Specifically, the cooperation between the protruding ring 511 and the recessed ring 121 can not only install the rotating cylinder 51 on the supporting foot 12, but also support the rotating cylinder 51 to rotate on the supporting foot 12. The rotating cylinder 51 drives the cutting rope 52 to rotate during high-speed rotation. Under the action of strong centrifugal force, the cutting rope 52 remains in a straight state. When the cutting rope 52 is swung at high speed, a high-intensity lateral impact force and shear force are formed on the surrounding weeds, so that the weeds are broken in half, thereby achieving the purpose of cutting and preventing the weeds from blocking the light too high. Since the cutting rope 52 has no sharp or pointed objects, it will not cause great damage to the surrounding humans and animals even during operation, thereby ensuring safety. The cutting rope 52 is in a hanging state when it is in a rest state.

[0033] Specifically, the cutting rope 52 is made of a material with high strength and certain toughness, such as nylon rope or braided steel wire rope, so that it can ensure the cutting force while not being easy to break or get entangled. A certain degree of wear will not affect the shearing effect of the cutting rope 52, avoiding the problems that occur during traditional blade cutting, and the cutting force is stable; the cross-section of the cutting rope 52 is best to be circular, so that the cutting rope 52 can form a line contact when it rotates and contacts the weeds in front, and the impact force on the weeds is concentrated on the contact line, forming a cutting force on the weeds, thereby achieving a shearing effect on the weeds; in order to enable the cutting rope 52 to obtain sufficient tension to make it taut when it rotates and swings, a steel block 521 is fixed to the tail end of the cutting rope 52.

[0034] A connecting portion 512 is provided on the outer side wall of the rotating cylinder 51 , and one end of the cutting rope 52 is installed on the rotating cylinder 51 through the connecting portion 512 .

[0035] Specifically, a cavity is provided in the connection part 512 , and the end of the cutting rope 52 is inserted into the connection part 512 and is knotted in the cavity. The connection part 512 may also be a welding point between the cutting rope 52 and the rotating cylinder 51 .

[0036] The motor 4 is installed in the middle of the bottom surface of the horizontal frame 11, and the output end of the motor 4 faces downward and is installed with an output shaft; the transmission assembly 6 includes a transmission wheel 61 and a transmission belt 62, and there are four groups of transmission wheels 61 and transmission belts 62. The output shaft is connected to two of the rotating cylinders 51 through a group of transmission wheels 61 and transmission belts 62, and the above-mentioned two rotating cylinders 51 are each connected to the remaining two rotating cylinders 51 through a group of transmission wheels 61 and transmission belts 62.

[0037] Specifically, when the motor 4 drives the output shaft to rotate, the output shaft first drives the two rotating cylinders 51 to rotate through the transmission wheel 61 and the transmission belt 62. The above two rotating cylinders 51 then drive the remaining two rotating cylinders 51 to rotate synchronously through the transmission wheel 61 and the transmission belt 62. The rotating cylinder 51 drives the cutting rope 52 to rotate, hit the surrounding weeds and achieve a shearing effect.

[0038] The center points of two adjacent connecting parts 512 are not on the same horizontal plane; the length of the cutting rope 52 is smaller than the vertical distance from the output shaft to the rotating cylinder 51 .

[0039] Specifically, the rotational motion trajectories of adjacent cutting ropes 52 are not on the same horizontal plane, so that the cutting ropes 52 do not interfere with or conflict with each other during operation. Thus, the motion trajectories of adjacent cutting ropes 52 can overlap, thereby improving the comprehensiveness of the cutting coverage.

[0040] Working principle: by adjusting the length of the telescopic rod 31, one side of the solar panel 2 can be adjusted to a suitable height and fixed at the angle, so that the receiving surface of the solar panel 2 can maintain the best light energy conversion angle with the sunlight; when the motor 4 drives the output shaft to rotate, the output shaft first drives the two rotating cylinders 51 to rotate through the transmission wheel 61 and the transmission belt 62, and the above two rotating cylinders 51 each drive the remaining two rotating cylinders 51 to rotate synchronously through the transmission wheel 61 and the transmission belt 62, and the rotating cylinder 51 drives the cutting rope 52 to rotate at a high speed. When the cutting rope 52 is swung at a high speed, a high-intensity lateral impact force and shear force are formed on the surrounding weeds, so that the weeds are cut off in the middle, thereby forming a shearing effect.
