Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic modules, in particular to a roof photovoltaic module with a self-cleaning structure. Background Art

[0002] The roof consists of three parts: roofing, insulation layer and load-bearing structure. It must bear its own load and the load above it. The load above it includes wind, snow, and the load of equipment, components, vegetation and people who need to be placed on the roof, and these loads are transferred to the foundation through the walls or columns below it. Photovoltaic components are a component installed on the roof by people living in rural areas to reduce energy consumption. Solar panels are very common equipment in photovoltaic components. They are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame, and have the characteristics of long service life and strong mechanical resistance to external compressive force.

[0003] In order to reduce energy consumption, people living in rural areas install photovoltaic modules on their roofs to generate solar power, thereby reducing electricity consumption. Rooftop photovoltaic modules are basically installed outdoors. With the increase of working hours and the blowing of wind and sand, the outer wall of the solar panel is inevitably covered with dust, which affects the power generation efficiency of the solar panel. At this time, the solar panel needs to be cleaned. However, the daily maintenance and cleaning of rooftop photovoltaic modules basically relies on rainwater flushing, or people climb onto the roof and use towels and other tools to manually clean them. This cleaning method is relatively cumbersome, resulting in people not frequently cleaning the solar panels, which in turn causes the surface of the solar panel to be uncleaned for a long time, which in turn affects the light transmittance of the photovoltaic modules, thereby affecting the power generation effect of the solar panels. Summary of the invention

[0004] The purpose of the present invention is to provide a roof photovoltaic module with a self-cleaning structure to solve the problem that the roof photovoltaic module proposed in the above background technology is basically flushed by rainwater when in use, or people have to clean it manually, which is a cumbersome cleaning method and thus affects the light transmittance of the photovoltaic module, thereby failing to meet people's usage needs.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rooftop photovoltaic assembly with a self-cleaning structure, comprising a movable panel, a protective frame and a solar panel body, the movable panel is docked with the protective frame through a hinge mechanism, and the interior of the protective frame is docked with the solar panel body through a storage cavity, one side of the movable panel is docked with a motor mounting box, and a driving motor is installed inside the motor mounting box, and the output end of the driving motor is docked with a rotating rod, a side of the rotating rod away from the driving motor is rotatably connected to a transmission rod, and a side of the transmission rod away from the rotating rod is movably connected to a guide rod, and a side of the guide rod close to the transmission rod is rotatably connected to a first connecting rod, and a side of the guide rod away from the transmission rod is rotatably connected to a second connecting rod.

[0006] Preferably, a connecting shaft is butted inside the first connecting rod and the second connecting rod on a side away from the guide rod, and the first connecting rod and the second connecting rod are parallel to each other.

[0007] Preferably, the connecting shaft is connected to the movable plate, and the first connecting rod and the second connecting rod are both rotatably connected to a cleaning rod on one side close to the guide rod.

[0009] Preferably, an ejection block is butt-jointed to the top end of the ejection spring, and storage cavities are provided inside both sides of the movable plate.

[0010] Preferably, a linkage block is slidably connected inside the storage cavity, and a connecting cavity is opened inside the linkage block.

[0011] Preferably, a connecting rod is butted against the inside of the connecting cavity, and a threaded pin is fixedly connected to one side of the connecting rod close to the protective frame.

[0012] Preferably, a positioning pin is fixedly connected to the side of the linkage block close to the threaded pin, and a limiting pin is slidably connected internally to the side of the linkage block away from the threaded pin, and a threaded hole that docks with the threaded pin is opened on the side of the top of the protective frame close to the linkage block.

[0013] Preferably, a rubber pad is sleeved on the outer wall of the solar panel body, and a rubber pad is butted against a side of the movable panel close to the solar panel body.

[0014] Preferably, guide grooves are provided on both sides of the movable plate, and a guide groove is provided at the bottom end of the movable plate.

[0015] Compared with the prior art, the beneficial effect of the present invention is that when the roof photovoltaic assembly with a self-cleaning structure is in use, the driving motor is started to rotate the bottom end of the cleaning rod along the connecting shaft, thereby automatically cleaning the dust on the surface of the movable plate, and then preventing dust from accumulating on the movable plate, thereby having an automatic cleaning function, and the threaded pin is disengaged from the threaded hole by rotating the connecting rod. At this time, the ejection block drives the movable plate to move upward, making it convenient for people to open the movable plate to maintain the solar panel body, and there is no need to use special installation tools to disassemble the protective frame, thereby having the function of facilitating maintenance during the use of the roof photovoltaic assembly.

[0016] 1. In order to reduce energy consumption, people install photovoltaic modules on the roof for solar power generation. As the working time increases, the outer wall of the photovoltaic module is covered with dust, which affects the power generation efficiency of the solar panel. When the solar panel needs to be cleaned, the driving motor is first started to drive the rotating rod to rotate. The rotation of the rotating rod causes the transmission rod to move. Then the transmission rod moves through the guide rod to drive the first connecting rod and the second connecting rod to rotate, so that the bottom end of the cleaning rod rotates along the connecting shaft, and then the dust on the surface of the movable panel is automatically cleaned without manual cleaning, thereby preventing dust accumulation from affecting the light transmittance of the solar panel body, so that the roof photovoltaic module has an automatic cleaning function during use;

In the process of solar power generation, as the working time increases, when the solar panels need to be maintained, first rotate the connecting rod to move the linkage block along the limit pin until the positioning pin and the positioning hole, the threaded pin and the threaded hole are disconnected. At this time, the ejection spring resets to generate an upward thrust on the ejection block, and the movable plate is lifted. At this time, the movable plate is opened to perform regular maintenance on the main body of the solar panel. In addition, the protective frame can be disassembled to maintain the main body of the solar panel without using special installation tools such as wrenches, so that the roof photovoltaic module has the function of facilitating maintenance during use;

[0018] 3. When people install photovoltaic modules on the roof to generate solar power and reduce electricity consumption, when it is windy and rainy, the rubber plug and rubber pad cooperate with each other to absorb the impact of the wind and protect the main body of the solar panel. Then the rainwater is quickly guided through the diversion groove, so that the roof photovoltaic modules have the functions of protection and diversion during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In specific implementation, in order to reduce energy consumption, people install photovoltaic modules on the roof to generate solar power to reduce electricity consumption. As the working time increases, the outer wall of the photovoltaic module is covered with dust, which affects the power generation efficiency of the solar panel. When the solar panel needs to be cleaned, the drive motor 5 in the motor installation box 4 is first started. The drive motor 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 causes the transmission rod 7 to move. Then the transmission rod 7 moves to drive the first connecting rod 9 to rotate. The rotation of the first connecting rod 9 drives the second connecting rod 10 to rotate through the guide rod 8, so that the bottom end of the cleaning rod 12 rotates along the connecting shaft 11, and then the dust on the surface of the movable plate 1 is automatically cleaned without manual cleaning, thereby preventing dust from accumulating on the movable plate 1 and affecting the light transmittance of the solar panel main body 3. Therefore, during the use of the roof photovoltaic module, it has an automatic cleaning function.

[0029] See also Figure 2 , Figure 5 and Figure 6It can be seen that ejection cavities 15 are provided on both sides of the middle of the top of the protective frame 2, and an ejection spring 13 is connected to the inside of the ejection cavity 15; an ejection block 14 is connected to the top of the ejection spring 13, and storage cavities 16 are provided inside the two sides of the movable plate 1; a linkage block 17 is slidably connected to the inside of the storage cavity 16, and a connecting cavity 18 is provided inside the linkage block 17; a connecting rod 19 is connected to the inside of the connecting cavity 18, and a threaded pin 20 is fixedly connected to the side of the connecting rod 19 close to the protective frame 2; a positioning pin 21 is fixedly connected to the side of the linkage block 17 close to the threaded pin 20, and a limiting pin 22 is slidably connected to the inside of the linkage block 17 away from the threaded pin 20, and the top of the protective frame 2 close to the linkage block 17 A threaded hole 23 is provided on one side of the solar panel body 3 and is docked with the threaded pin 20; a rubber pad 24 is sleeved on the outer wall of the solar panel body 3, and the rubber pad 24 is docked on the side of the movable panel 1 close to the solar panel body 3; the linkage block 17 is symmetrically distributed about the vertical center line of the movable panel 1, and the limit pin 22 is connected to the movable panel 1, and an elastic telescopic mechanism is formed between the movable panel 1, the protective frame 2, the ejection spring 13 and the ejection block 14, and the ejection spring 13 is symmetrically distributed about the vertical center line of the protective frame 2, and a positioning hole docking with the positioning pin 21 is provided on the side of the top of the protective frame 2 close to the threaded hole 23, and the positioning pin 21 and the threaded pin 20 are parallel to each other.

[0030] During specific implementation, in order to reduce energy consumption, people install photovoltaic modules on the roof to generate solar power and thus reduce electricity consumption. As the working time increases, when the solar panel needs to be maintained, the connecting rod 19 is first rotated to move. The movement of the connecting rod 19 drives the linkage block 17 to move together through the connecting cavity 18, so that the linkage block 17 moves along the limit pin 22 and the storage cavity 16 until the positioning pin 21 is disconnected from the positioning hole and the threaded pin 20 is disconnected from the threaded hole 23. At this time, the ejection spring 13 in the ejection cavity 15 is reset, and an upward thrust is generated on the ejection block 14, driving the movable plate 1 to move upward a distance. At this time, the movable plate 1 is opened to perform regular maintenance on the solar panel main body 3, and then the protective frame 2 can be disassembled to maintain the solar panel main body 3 without using special installation tools such as wrenches, so that the roof photovoltaic module has the function of easy maintenance.

[0031] See also Figure 1 , Figure 3 and Figure 4 It can be seen that guide grooves 26 are opened on both sides of the movable plate 1, and a guide groove 27 is opened at the bottom of the movable plate 1; the guide grooves 27 are evenly distributed on the movable plate 1, and the guide grooves 26 are evenly distributed on the movable plate 1, the rubber plugs 25 are symmetrically distributed about the vertical center line of the movable plate 1, and the rubber pads 24 are connected to the protective frame 2.

[0032] In specific implementation, in order to reduce energy consumption, people install photovoltaic modules on the roof to generate solar power and thus reduce electricity consumption. When windy and rainy weather occurs, the bottom end of the rubber plug 25 is connected to the solar panel body 3 to limit the position of the solar panel body 3 to prevent the solar panel body 3 from moving at will. Then, the rubber pad 24 is used to protect the solar panel body 3 to absorb the impact force generated by the wind. Then, the guide groove 26 and the guide groove 27 cooperate with each other to divert rainwater, and then the rainwater is quickly guided, so that during the use of the roof photovoltaic module, it has the functions of convenient protection and diversion.

[0033] In summary, when the roof photovoltaic assembly with a self-cleaning structure is used, in order to reduce energy consumption, when people install the photovoltaic assembly on the roof, they first open the movable panel 1, then put the solar panel body 3 into the protective frame 2, and then close the movable panel 1. At this time, the photovoltaic assembly is installed on the roof, and solar power generation is performed in sunny weather, thereby reducing the daily electricity consumption of residents. By starting the driving motor 5 to cause the first connecting rod 9 and the second connecting rod 10 to rotate together, the bottom end of the cleaning rod 12 rotates along the connecting shaft 11, and then the dust on the surface of the movable panel 1 is automatically cleaned, and then the dust on the surface of the movable panel 1 is prevented. To prevent dust from accumulating on the movable plate 1 and affecting the light transmittance of the solar panel main body 3, the linkage block 17 is moved along the limit pin 22 by rotating the connecting rod 19 until the positioning pin 21 and the positioning hole, and the threaded pin 20 and the threaded hole 23 are disconnected. At this time, the ejection block 14 drives the movable plate 1 to move upward, making it convenient for people to open the movable plate 1 to maintain the solar panel main body 3, and then the protective frame 2 can be disassembled to maintain the solar panel main body 3 without using special installation tools such as wrenches.
