Description

Technical Field

[0001] This utility model relates to the field of photovoltaic snow removal technology, and specifically discloses a snow removal device for photovoltaic carports. Background Technology

[0002] Photovoltaic modules generate electricity by relying on solar light. As the foundation of photovoltaic power generation, the photoelectric conversion efficiency of photovoltaic panels is closely related to the weather. The most concentrated areas of photovoltaic power generation in my country are located in plateau regions such as Xinjiang and Tibet. Due to their geographical location, Xinjiang and Tibet have an exceptionally long snow season of up to 7 months each year. When it snows, snowflakes accumulate on the panels, blocking direct sunlight. Since the snow cannot melt on its own, it may even freeze if it is not cleaned for a long time, requiring manual or robotic removal.

[0003] Because of the high location of the carport, traditional methods of clearing snow from the photovoltaic carport, such as manual sweeping, are inefficient, costly, and pose safety risks. When existing snow removal equipment is used, the snow freezes into ice, and there is both snow and ice on the photovoltaic carport, making it difficult for the equipment to remove the snow and ice, resulting in unsatisfactory cleaning results. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a snow removal device for photovoltaic carports, so as to solve the technical problem that existing snow removal equipment has difficulty in removing ice and snow from photovoltaic carports when clearing ice and snow mixtures, resulting in unsatisfactory cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a snow removal device for a photovoltaic carport, comprising several sets of photovoltaic panels, a traveling trolley disposed between two rows of photovoltaic panels, the traveling trolley being provided with two sets of cleaning mechanisms for cleaning adjacent photovoltaic panels; and the traveling trolley being provided with a control mechanism for controlling the movement of the cleaning mechanisms.

[0006] Furthermore, the cleaning mechanism includes a lifting device, which includes lifting blocks. One set of lifting blocks of the cleaning mechanism is provided with a rotatable first connecting frame, which is L-shaped. The other set of lifting blocks of the cleaning mechanism is provided with a rotatable second connecting frame, which is U-shaped. The traveling trolley is provided with a blower assembly, which includes an air outlet. The air outlet is fixedly connected to the first connecting frame / second connecting frame.

[0007] Furthermore, the blower assembly includes a drive unit, which is fixedly connected to the traveling trolley. The drive unit is provided with a connecting pipe, which is connected to the air outlet. The air outlet is parallel to the photovoltaic panel, and an auxiliary heating module is provided on the air outlet.

[0008] Furthermore, a mating column is fixedly connected to the first connecting frame / second connecting frame, and a mating sleeve is provided on the air outlet. The mating column and the mating sleeve are rotatably connected. A torsion spring is provided inside the mating sleeve and is fitted on the mating column. The two ends of the torsion spring are fixedly connected to the mating column and the mating sleeve, respectively.

[0009] Furthermore, a control mechanism is provided between the first connecting frame / second connecting frame and the traveling trolley. The control mechanism includes a cylinder, a first movable block is provided on the cylinder, and a fixed seat is provided on the traveling trolley. The first movable block is hinged to the fixed seat. A second movable block is provided at the telescopic end of the cylinder, and a fixed column is fixedly connected to the second movable block. The fixed column is mounted on the first connecting frame / second connecting frame.

[0010] Furthermore, the traveling trolley is equipped with a rotating device, and the output end of the rotating device is equipped with a limit rod.

[0011] The working principle and beneficial effects of this solution are as follows:

[0012] In use, the staff first controls the trolley to move between the two rows of photovoltaic panels, then starts the cylinder to move the first / second connecting frame and the air outlet, so that the air outlet is parallel to the photovoltaic panel. Then the lifting device is started, and the cylinder is simultaneously controlled to extend and retract to ensure that the air outlet is raised and lowered vertically, so that the air outlet is moved to a suitable height for easy snow removal.

[0013] When clearing snow, the drive device delivers airflow to the air outlet through the pipe to disperse the snow. If the snow is frozen, the heating auxiliary module can be activated to heat the airflow from the air outlet. At the same time, the air outlet is controlled to move vertically downward so that it is closer to the photovoltaic panel, making it easier to melt and remove the snow.

[0020] The following detailed description illustrates the specific implementation method:

[0021] Example

[0022] like Figures 1 to 4 As shown, a snow removal device for a photovoltaic carport is disclosed, including several sets of photovoltaic panels 1, a traveling trolley 2 is arranged between two rows of photovoltaic panels 1, and two sets of cleaning mechanisms are arranged on the traveling trolley 2. The two sets of cleaning mechanisms clean the two rows of photovoltaic panels 1 adjacent to the traveling trolley 2 respectively.

[0023] The cleaning mechanism includes a lifting device 3, which includes a lifting block. One set of lifting blocks of the cleaning mechanism is equipped with a first connecting frame 4, which is L-shaped. The other set of lifting blocks of the cleaning mechanism is equipped with a second connecting frame 5, which is U-shaped. One end of the first connecting frame 4 / second connecting frame 5 is rotatably connected to the lifting block. A blower assembly is provided on the traveling trolley 2. The blower assembly includes a drive device, which is fixedly connected to the traveling trolley 2 by bolts. A connecting pipe is connected to the drive device, and an air outlet 6 is provided on the connecting pipe. The air outlet 6 is connected to the drive device through the connecting pipe. The air outlet 6 is also rotatably connected to the first connecting frame 4 / second connecting frame 5. The air outlet 6 is parallel to the photovoltaic panel 1, and an auxiliary heating module is provided on the air outlet 6.

[0024] A mating column 7 is fixedly connected to the first connecting frame 4 / second connecting frame 5, and a mating sleeve 8 is provided on the air outlet 6. The mating column 7 is inserted into the mating sleeve 8, and a torsion spring 9 is provided inside the mating sleeve 8. The mating column 7 is inserted at the center of the torsion spring 9, and the two ends of the torsion spring 9 are fixedly connected to the mating column 7 and the mating sleeve 8 respectively.

[0025] A control mechanism is provided between the first connecting frame 4 / second connecting frame 5 and the traveling trolley 2. The control mechanism includes a cylinder 10, on which a first movable block 11 is provided. The fixed end of the cylinder 10 is fixedly connected to the first movable block 11 by bolts. A fixed seat 12 is provided on the traveling trolley 2. A sliding groove 13 is provided on the fixed seat 12. The first movable block 11 is hinged to the fixed seat 12 and slidably locked in the sliding groove 13. A second movable block 14 is provided at the telescopic end of the cylinder 10. A fixed column 15 is fixedly connected to the second movable block 14. A fixed groove 16 is provided on the first connecting frame 4 / second connecting frame 5, and the fixed column 15 passes through the fixed groove 16.

[0026] The traveling trolley 2 is equipped with a rotating device 17. The fixed end of the rotating device 17 is fixedly connected to the traveling trolley 2 by bolts. The output end of the rotating device 17 is equipped with a limit rod 18. The rotating device 17 and the limit rod 18 are located on the side close to the second connecting frame 5.

[0027] Among them, photovoltaic panel 1, traveling trolley 2, lifting device 3, cylinder 10, rotating device 17, driving device and auxiliary heating module are all technical means commonly used by those skilled in the art, and their structure, connection method and usage are well known to those skilled in the art.

[0028] In practice

[0029] In use, the operator first controls the traveling trolley 2 to move between the two rows of photovoltaic panels 1, then activates cylinder 10. The telescopic end of cylinder 10 extends, driving the second movable block 14 to move. The second movable block 14 then drives the fixed column 15 and the first connecting frame 4 /

[0030] When the second connecting frame 5 moves, the fixed column 15 drives the first connecting frame 4 / second connecting frame 5 to move. The fixed column 15 rotates in the fixed groove 16, and the second movable block 14 rotates relative to the first connecting frame 4 / second connecting frame 5. At the same time, the fixed end of the cylinder 10 drives the first movable block 11 to rotate on the fixed seat 12. The first movable block 11 slides in the sliding groove 13. When the first connecting frame 4 / second connecting frame 5 moves, one end rotates on the lifting device 3, driving the air outlet 6 to move until the air outlet 6 is parallel to the photovoltaic panel 1. Then the lifting device 3 is started, and the cylinder 10 is simultaneously controlled to extend and retract to ensure that the air outlet 6 is vertically raised and lowered, so that the air outlet 6 is moved to a suitable height to clear the snow.

[0031] When clearing snow, the drive unit is first started. The drive unit delivers airflow to the air outlet 6 through the pipe. At the same time, the wind speed and air volume of the drive unit are adjusted according to the thickness of the snow to adapt to different snow conditions. In particularly cold or icy conditions, the heating auxiliary module can be activated to heat the airflow blown out of the air outlet 6. At the same time, the lifting device 3 can be controlled to move vertically downward through cooperation with the cylinder 10, so that the air outlet 6 is closer to the photovoltaic panel 1, making it easier to melt and clear the snow.

[0032] After the snow on the photovoltaic panel 1 is cleared, the control cylinder 10 retracts. The cylinder 10, through the second movable block 14 and the fixed column 15, drives the first connecting frame 4 / second connecting frame 5 to rotate, causing the air outlet 6 to move away from the photovoltaic panel 1. This continues until the cylinder 10 moves the first connecting frame 4 / second connecting frame 5 to a vertical position. Then, the lifting device 3 is activated, simultaneously retracting the cylinder 10 until the first connecting frame 4 / second connecting frame 5 moves to the bottom of the lifting device 3. At the same time, the cylinder 10 cooperates with this, causing the first connecting frame 4 / second connecting frame 5 and the air outlet 6 to move away from the photovoltaic panel 1. The air outlet 6 moves vertically downwards, and then the rotating device 17 is activated. The output end of the rotating device 17 drives the limiting rod 18 to rotate. The limiting rod 18 first contacts the air outlet 6. At this time, since the air outlet 6 is inclined, when the limiting rod 18 rotates, it can drive the air outlet 6 to rotate around the second connecting frame 5. When rotating, the mating column 7 rotates in the mating sleeve 8, and at the same time drives the torsion spring 9 to twist, so that the torsion spring 9 is full of elastic potential energy until the limiting rod 18 moves to one end of the air outlet 6 and stops. At this time, the air outlet 6 is in a horizontal state, so that the air outlet 6 is located in the traveling trolley 2.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
