Description

Technical Field

[0001] This invention relates to the field of photovoltaic carport technology, and in particular to a photovoltaic carport with automatic snow removal function. Background Technology

[0002] Photovoltaic carports, as a new type of facility combining parking and photovoltaic power generation, are widely used in various locations. However, in cold winter regions, the roofs of photovoltaic carports are prone to snow accumulation. Snow covering the photovoltaic panels not only blocks solar radiation, leading to a significant decrease in photovoltaic power generation efficiency or even a complete halt in power generation, but the melting snow and subsequent freezing or long-term accumulation can also cause corrosion or damage to the photovoltaic panel surface. Existing snow removal methods mostly rely on manual sweeping, which is not only labor-intensive and inefficient, but also poses significant safety hazards due to the height of photovoltaic carports, where manual work at height is typically required. Although some snow removal devices have emerged on the market, they are often complex in structure and struggle to ensure effective snow removal while avoiding scratches on the photovoltaic panel surface.

[0003] Therefore, it is particularly important to develop a photovoltaic carport with automatic snow removal function that is highly automated, has good snow removal effect, and is safe and reliable. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a photovoltaic carport with automatic snow removal function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic carport with automatic snow removal function includes multiple columns, the top of which is jointly equipped with a photovoltaic carport, and the bottom of the columns is fixed to the ground by fixing seats and anchor rods. The photovoltaic carport includes two symmetrical inclined canopies. The top surface of the photovoltaic carport is covered with photovoltaic panels. The photovoltaic panels are mounted on bases at both their high and low points. Pressure sensors are mounted on the top surface of the bases. A movable snow removal assembly is installed between the two bases. The snow removal assembly is driven by a lateral drive assembly, which moves along the length of the base and in contact with the photovoltaic panels. The top surfaces of the two bases are fixed with guide rails, and a carriage is slidably mounted on the guide rails. The carriage is detachably mounted to both ends of the snow removal assembly.

[0007] Furthermore, the snow removal assembly includes a central heating box, with side boxes symmetrically fixed on both sides of the heating box. A cleaning roller is rotatably installed inside the side box, and the cleaning roller makes frictional contact with the top surface of the photovoltaic panel.

[0008] Furthermore, a fan drive motor is mounted on the inner side of the heating box via a bracket, and a fan is mounted on the drive shaft of the fan drive motor. Multiple air holes are opened on the side of the heating box near the top, and an electric heating wire is installed inside the heating box.

[0009] Furthermore, the cleaning roller is rotatably mounted to the side box via both ends of the roller shaft; the lateral drive assembly includes gears mounted at the ends of the roller shaft, and both ends of the roller shaft extend to the outside of the heating box and are equipped with gears; a rack is fixed to the side of the base, and the gears mesh with the rack; the two roller shafts are connected and driven by a belt drive assembly.

[0010] Furthermore, a transverse drive motor is installed at one end of the side box, and the drive shaft of the transverse drive motor is connected to the roller shaft for transmission via a belt drive assembly.

[0011] Furthermore, the slide has an L-shaped structure, with a limit slider fixed at one end. The limit slider is slidably disposed inside the guide rail. A second bolt is installed at the other end of the slide, and the slide is detachably installed to the end of the heating box via the second bolt.

[0012] Furthermore, a fixing plate is installed at both ends of the base, and a first bolt is installed at the lower end of each fixing plate, and the base is detachably installed to the bottom surface of the photovoltaic carport via the first bolt.

[0013] Furthermore, the cleaning roller includes a plurality of elongated roller brushes detachably mounted to the roller shaft, and the roller brushes make frictional contact with the top surface of the photovoltaic panel.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a movable snow removal component, uses a transverse drive component to drive the snow removal component to move on the surface of the photovoltaic panel. In conjunction with the rotation of the sweeping roller, it can automatically remove the snow accumulated on the surface of the photovoltaic panel without manual intervention, thus improving snow removal efficiency and safety.

[0015] 2. The present invention has a heating box in the center of the snow removal component, which integrates heating wire and fan.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0021] Reference Figure 1-7 A photovoltaic carport with automatic snow removal function includes multiple columns 1, with a photovoltaic carport 2 installed on the top of the multiple columns 1, and the bottom of the columns 1 is fixed to the ground by fixing seats and anchor rods.

[0022] The photovoltaic carport 2 includes two symmetrical inclined canopies. The top surface of the photovoltaic carport 2 is covered with photovoltaic panels 21. The photovoltaic panels 21 are equipped with bases 3 on the top surface at both the high and low points. Pressure sensors are installed on the top surface of the bases 3. A movable snow removal component 4 is installed between the two bases 3. The snow removal component 4 is driven by a lateral drive component to move along the length of the bases 3 and in contact with the photovoltaic panels 21. The top surfaces of the two bases 3 are fixed with guide rails 5, and a carriage 6 is slidably mounted on the guide rails 5. The carriage 6 is detachably mounted to both ends of the snow removal assembly 4.

[0023] The snow removal assembly 4 includes a heating box 41 located in the center, and side boxes 42 are symmetrically fixed on both sides of the heating box 41. A cleaning roller 43 is rotatably installed inside the side box 42, and the cleaning roller 43 is in frictional contact with the top surface of the photovoltaic panel 21.

[0024] A fan drive motor 46 is mounted on the inner side of the heating box 41 via a bracket 45. A fan 47 is mounted on the drive shaft of the fan drive motor 46. Multiple air holes 49 are opened on the side of the heating box 41 near the top. An electric heating wire 48 is installed inside the heating box 41.

[0025] The cleaning roller 43 is rotatably mounted to the side box 42 via both ends of the roller shaft 44; the transverse drive assembly includes gears 9 mounted on the ends of the roller shaft 44, and both ends of the roller shaft 44 extend to the outside of the heating box 41 and are equipped with gears 9; a rack 7 is fixed to the side of the base 3, and the gears 9 and rack 7 mesh with each other; the two roller shafts 44 are connected and driven by a belt drive assembly 10.

[0026] A transverse drive motor 8 is installed at one end of the side box 42, and the drive shaft of the transverse drive motor 8 is connected to the roller shaft 44 for transmission through the belt drive assembly 10.

[0027] The slide 6 has an L-shaped structure, with a limiting slider 62 fixed at one end. The limiting slider 62 is slidably disposed inside the guide rail 5. A second bolt 61 is installed at the other end of the slide 6, and the slide 61 is detachably installed to the end of the heating box 41 through the second bolt 61.

[0028] Both ends of the base 3 are equipped with fixing plates 31, and the lower ends of the fixing plates 31 are equipped with first bolts 32, which can be detachably installed to the bottom surface of the photovoltaic carport 2 through the first bolts 32.

[0029] The cleaning roller 43 includes a plurality of elongated roller brushes that are detachably mounted to the roller shaft 44, and the roller brushes make frictional contact with the top surface of the photovoltaic panel 21.

[0030] The core principle of this device lies in the "coordinated operation of mechanical sweeping and hot air snow melting", supplemented by "automatic triggering by pressure sensing".

[0031] Composite snow removal mechanism: The heating box installed in the center of the snow removal component generates heat through internal heating wires, and the hot air driven by the fan blows out from the air holes to preheat the snow on the surface of the photovoltaic panel or melt the ice in real time; at the same time, the sweeping rollers rotating in the side boxes on both sides remove the snow or melted snow water through physical friction.

[0032] Transmission and guiding mechanism: The drive method of gear and rack meshing is adopted, and the belt drive component is used to realize the synchronous rotation of the two rollers; the sliding cooperation between the L-shaped carriage and the guide rail ensures that the snow removal component runs stably along a straight line on the inclined canopy and always keeps in contact with the surface of the photovoltaic panel.

[0033] Intelligent control mechanism: Based on the pressure sensor on the base, the system monitors the snow load in real time and automatically starts when the preset threshold is reached, realizing unattended automated operation.

[0034] The complete workflow of this device can be divided into three stages: status monitoring, snow removal operation, and reset / standby.

[0035] Status monitoring and triggering

[0036] Snow accumulation sensing: During winter snowfall, pressure sensors installed on the high and low points of the photovoltaic panel base monitor the weight of snow accumulation on the photovoltaic panel surface in real time.

[0037] Signal triggering: When the weight of the accumulated snow reaches the system's preset threshold, the sensor sends a signal to the control system to automatically start the snow removal program.

[0038] Snow removal operation

[0039] Component startup: The transverse drive motor starts, and the fan drive motor starts working at the same time.

[0040] Hot air snow melting: The fan-driven motor rotates the fan, and the airflow is heated by the heating wire and blown onto the surface of the photovoltaic panel through the air holes on the side of the heating box, which accelerates the melting of snow and prevents ice from sticking together.

[0041] Mechanical cleaning:

[0042] The transverse drive motor drives the roller shaft and cleaning roller to rotate through the belt drive assembly, and performs friction cleaning on the surface of the photovoltaic panel.

[0043] At the same time, the belt drive assembly transmits power to the roller on the other side, ensuring that the two cleaning rollers work synchronously.

[0044] Lateral movement:

[0045] The gear at the end of the roller meshes with the rack on the side of the base. As the roller rotates, the gear travels on the rack, driving the entire snow removal assembly to move smoothly from one end of the photovoltaic panel to the other along the length of the base.

[0046] During this process, the limit slider on the carriage slides within the guide rail, providing stable support and guidance to prevent component displacement.

[0047] Loop and Reset

[0048] Reciprocating operation: After the snow removal component moves to the end of the photovoltaic panel, the control system controls the motor to reverse and drive the component back to the initial position. It can perform multiple reciprocating cleaning operations according to the snow thickness.

[0049] Operation complete: When the pressure sensor detects that the snow weight has dropped below the safety threshold, or after the preset number of cleaning cycles has been completed, the system automatically stops heating and cleaning, the device resets and enters standby mode.
