Description

Technical Field

[0001] The invention relates to the field of photovoltaic power generation panels, and more particularly to a photovoltaic power generation panel with a rain collection function. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] The use of photovoltaic panels is very common nowadays, especially on civilian roofs. This is not only environmentally friendly but also can make full use of new energy, which can reduce the country's energy consumption for power generation to a certain extent.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 9 A photovoltaic power generation panel with a rain collecting function comprises a base 1, a photovoltaic power generation panel bracket 2 is fixedly connected to the upper surface of the base 1, a photovoltaic power generation panel body 3 is fixedly connected to the top of the photovoltaic power generation panel bracket 2, and an anti-evaporation component 4 is provided on the front side of the upper surface of the base 1 to prevent rainwater evaporation.

[0043] like Figure 2 and Figure 3 As shown, the anti-evaporation component 4 includes a collection box 41 fixed on the upper surface of the base 1, a limiting rod 46 is fixedly connected to the bottom of the collection box 41, a foam float 48 is slidably connected to the outer surface of the limiting rod 46, trapezoidal guide blocks 47 are fixedly connected on both sides of the inner surface of the collection box 41, and there is a certain gap between the four sides of the foam float 48 and the side of the collection box 41.

[0044] A side panel 42 is fixedly connected to one side of the collecting box 41, a mesh panel 44 for blocking debris is fixedly connected to one side of the side panel 42 at an angle, a shielding assembly 43 is fixedly connected to the side of the side panel 42 away from the mesh panel 44, a top rod 45 is fixedly connected to the upper surface of the foam floating plate 48, and a cooling assembly 5 is fixedly connected to the lower surface of the photovoltaic panel body 3.

[0045] When it rains, rainwater directly enters the collection box 41 through the mesh plate 44. Rainwater falling on the surface of the photovoltaic panel body 3 falls into the collection box 41 along the surface of the photovoltaic panel body 3. The water level inside the collection box 41 gradually rises, driving the foam float 48 to slide and rise on the surface of the trapezoidal guide block 47. When the water level gradually approaches the trapezoidal guide block 47, the foam float 48 contacts the bottom of the trapezoidal guide block 47, and seals and covers the entrance between the two trapezoidal guide blocks 47. In clear weather, the foam float 48 can block rainwater from the outside world, avoid direct contact between the high-temperature air outside and the rainwater, reduce the temperature of the rainwater, effectively slow down the evaporation rate of rainwater, reduce excessive rainwater loss inside the collection box 41, and also prevent some flying insects from entering the rainwater and polluting the rainwater.

[0046] like Figure 4 and Figure 5 As shown, the shielding assembly 43 includes two mounting plates 431 fixed on one side of the side plate 42 and electric slide rails 439 fixed on both sides of the mesh plate 44, the two mounting plates 431 are fixedly connected with coil springs 432 on the two sides away from each other, and the two mounting plates 431 are rotatably connected with reels 433 and wiping assemblies 434 on the sides close to each other, the two sides of the reels 433 pass through the interior of the mounting plates 431 and the coil springs 432, the outer surface of the reels 433 is wrapped with a sunshade cloth 4311, the two electric slide rails 439 are slidably connected with slide plates 435, one side of the sunshade cloth 4311 passes through the side plate 42 and is fixed to one side of the slide plate 435, and the side of the side plate 42 away from the reels 433 is fixedly connected with a trigger component for controlling the operation of the electric slide rail 439.

[0047] The trigger component includes two control switches 436 fixed on one side of the side panel 42. The two control switches 436 are fixedly connected with a slide rod 4310 near each other. A spring 437 is sleeved on the outer surface of the slide rod 4310. The outer surface of the slide rod 4310 is slidably connected with an L-shaped movable plate 438. The L-shaped movable plate 438 is located directly above the top rod 45.

[0048] A foam float 48 is provided to cover the surface of the rainwater, which can effectively slow down the evaporation rate of the rainwater. However, in clear weather, the sunlight will shine on the inside of the collection box 41, causing the temperature inside the collection box 41 to rise. The heat will be transferred to the rainwater through the collection box 41, affecting the effect of the foam float 48 in slowing down the evaporation rate of the rainwater.

[0049] On rainy days, the collection box 41 collects rainwater, and the water level of the rainwater rises. The foam floating plate 48 moves up synchronously with the rise of the water level, and the foam floating plate 48 drives the top rod 45 to move toward the L-shaped movable plate 438. When the top rod 45 contacts the L-shaped movable plate 438, the L-shaped movable plate 438 is pushed to move up synchronously, and the L-shaped movable plate 438 squeezes the slide bar 4310. When the foam floating plate 48 contacts the bottom of the trapezoidal guide block 47, the L-shaped movable plate 438 touches and opens the control switch 436 above, and the electric slide rail 439 is powered on. The slide plate 435 is driven by the driving force and moves inside the electric slide rail 439 away from the side plate 42, pulling the sunshade cloth 4311 to unfold from the outer surface of the reel 433. The reel 433 rotates synchronously and twists the coil spring 432. When the sunshade cloth 4311 covers the surface of the mesh plate 44, the sunshade cloth 4311 can shield the interior of the collection box 41, effectively blocking the sunlight and preventing the sunlight from directly irradiating the interior of the collection box 41. The setting of the sunshade cloth 4311 effectively reduces the temperature above the interior of the collection box 41, making the internal temperature of the collection box 41 lower than the surrounding external environment, further improving the effect of the foam float 48 on slowing down the evaporation rate of rainwater, and when the slide plate 435 moves on the surface of the mesh plate 44, it can push the debris on the surface of the mesh plate 44 away from the surface of the mesh plate 44, avoiding too much debris on the surface of the mesh plate 44 and affecting the efficiency of the collection box 41 in collecting rainwater.

[0050] When the rainwater inside the collection box 41 is in use and the water level of the rainwater inside drops, the water level inside the collection box 41 gradually drops, and the foam float 48 slides and drops on the outer surface of the limit rod 46 at the same time, driving the top rod 45 and the L-shaped movable plate 438 to separate from each other, and the slide rod 4310 pushes the L-shaped movable plate 438 to move downward, and the L-shaped movable plate 438 touches and opens with the control switch 436 below, and controls the electric slide rail 439 again, driving the slide plate 435 to move in the opposite direction, driving the sunshade cloth 4311 to move away from the surface of the mesh plate 44, and the reel 433 loses traction, and the winding spring 432 resets, driving the reel 433 to rotate in the opposite direction, and reeling the sunshade cloth 4311.

[0051] like Figure 5 As shown, the wiping assembly 434 includes a brush roller 4341 rotatably connected to the mounting plate 431 and second gears 4343 on both sides of the reel 433, and first gears 4342 are fixedly connected to both sides of the brush roller 4341 passing through the mounting plate 431, and the surface of the brush roller 4341 is in contact with the sunshade cloth 4311 wound on the reel 433.

[0052] Because the surface of the sunshade cloth 4311 will be covered with a lot of dust and debris when it is working, if it is not cleaned in time, the aging of the sunshade cloth 4311 will be accelerated and the service life of the sunshade cloth 4311 will be reduced.

[0053] When the reel 433 rotates and reels the sunshade cloth 4311, the reel 433 simultaneously drives the two second gears 4343 to rotate, the second gears 4343 drive the first gears 4342 meshing therewith to rotate, the two first gears 4342 drive the brush roller 4341 to rotate, and the brush roller 4341 wipes the surface of the sunshade cloth 4311 that is being reeled up by the reel 433, so as to wipe off the debris and dust adhering to the surface of the sunshade cloth 4311, thereby improving the cleanliness of the surface of the sunshade cloth 4311, delaying the aging of the sunshade cloth 4311, and increasing the service life of the sunshade cloth 4311.

[0054] like Figure 6 - Figure 8 As shown, the cooling component 5 includes a plurality of cooling frames 52 fixed on the lower surface of the photovoltaic panel body 3 and a fixed plate 514 at the middle of one side of the photovoltaic panel body 3, a connecting pipe 53 is connected between the two cooling frames 52, a water inlet pipe 54 is connected to one side of the leftmost cooling frame 52, the other end of the water inlet pipe 54 is connected to one side of the collecting box 41, a water outlet pipe 55 is connected to one side of the rightmost cooling frame 52, a piston cylinder 517 is fixedly connected to one side of the fixed plate 514, a second one-way valve 510 and a first one-way valve 56 are symmetrically provided on the outer surface of the piston cylinder 517, a piston 515 is slidably connected to the inside of the piston cylinder 517, and a driving component for driving the piston 515 to move back and forth is hinged on one side of the piston 515.

[0055] The flow direction of the first one-way valve 56 is from the outlet pipe 55 to the inside of the piston cylinder 517 , and the flow direction of the second one-way valve 510 is from the inside of the piston cylinder 517 to the second one-way valve 510 .

[0056] The driving component includes a third gear 58 rotating on the top of the fixed plate 514 and a guide rail 51 fixed on both sides of the photovoltaic panel body 3. The front side of a guide rail 51 is fixedly connected to a servo motor 512, and the output end of the servo motor 512 is fixedly connected to a threaded rod 513. The interior of the guide rail 51 is slidably connected to a dirt removal component 57. The threaded rod 513 penetrates the interior of the dirt removal component 57 and is connected by a thread. One side of the dirt removal component 57 is fixedly connected to a rack 511. The top of the third gear 58 is fixedly connected to a crank connecting rod 59. The outer surface of the crank connecting rod 59 is hinged with an articulated rod 516. One side of the articulated rod 516 is hinged to one side of the piston 515, and the third gear 58 is meshed with the rack 511.

[0057] In practice, the photovoltaic panel body 3 generates a certain amount of heat during operation. The power generation efficiency of the photovoltaic panel body 3 is affected by its internal temperature. High temperature will reduce the power generation efficiency of the photovoltaic panel body 3.

[0058] After the photovoltaic panel body 3 has been working for a period of time, the photovoltaic panel body 3 generates temperature inside, and the servo motor 512 is turned on to work, and the threaded rod 513 drives the dirt removal component 57 to reciprocate inside the guide rail 51, thereby driving the rack 511 to reciprocate, and the rack 511 drives the third gear 58 to rotate continuously, and the third gear 58 drives the crank connecting rod 59 to rotate, and the piston 515 is pulled to reciprocate inside the piston cylinder 517 through the hinged rod 516. When the piston 515 moves toward the third gear 58, the inside of the piston cylinder 517 is pulled, and the inside of the piston cylinder 517 is in a negative pressure state, and the first one-way valve 56 and the water outlet pipe 55 cooperate with each other to draw the air inside the cooling frame 52. Since the multiple cooling frames 52 are interconnected through the connecting pipe 53, when the gas inside the cooling frame 52 is exhausted, the rainwater inside the collection box 41 is transported to the inside of the cooling frame 52 through the water inlet pipe 54. The photovoltaic power generation panel body 3 transfers the heat through the cooling frame 52 to the water inside the cooling frame 52 through heat conduction. Since the third gear 58 continuously rotates, the piston 515 continuously moves back and forth, so that the water inside the cooling frame 52 continuously flows, and the water inside the collection box 41 continuously supplies to the inside of the cooling frame 52, effectively improving the cooling effect of the photovoltaic power generation panel body 3.

[0059] like Fig. 9 As shown, the dirt removal component 57 includes a cleaning plate 571 sliding inside the guide rail 51, a cleaning sponge 574 is fixedly connected to the front and rear sides of the lower surface of the cleaning plate 571, a spray pipe 573 is fixedly connected to the lower surface of the cleaning plate 571, and the outer surfaces of the spray pipe 573 are respectively connected to the first hose 572 and the second hose 575, one end of the first hose 572 is interconnected with the second one-way valve 510, and the other end of the second hose 575 is interconnected with the collecting box 41, a rack 511 is fixedly connected to one side of the cleaning plate 571, and the interior of the cleaning plate 571 is interconnected with the threaded rod 513 through threads.

[0060] When the photovoltaic panel body 3 is working in the outside world, it is in contact with sunlight, and the surface of the photovoltaic panel body 3 also has a very high temperature. In addition, dust on the surface of the photovoltaic panel body 3 will also have a certain impact on the efficiency of power generation.

[0061] When the third gear 58 drives the piston 515 to continuously reciprocate inside the piston cylinder 517 through the hinged rod 516, the water drawn from the water outlet pipe 55 will be transported to the inside of the first hose 572 through the second one-way valve 510 when the piston 515 is squeezed into the piston cylinder 517. The first hose 572 transports the water to the inside of the spray pipe 573, and the water is sprayed onto the surface of the photovoltaic panel body 3 through the spray pipe 573. Since the cleaning plate 571 continuously reciprocates on the surface of the photovoltaic panel body 3, the two cleaning sponges 574 wipe the surface of the photovoltaic panel body 3, and the water sprayed out by the spray pipe 573 Water can further improve the effect of cleaning the surface of the photovoltaic panel body 3. The cleaning sponge 574 can evenly wipe the rainwater on the surface of the photovoltaic panel body 3. The residual water can continuously absorb the heat of the photovoltaic panel body 3 and evaporate. It can not only further improve the cooling effect of the photovoltaic panel body 3, but also effectively avoid the influence of dust on the power generation efficiency of the photovoltaic panel body 3 by cleaning the dust. After wiping, the cleaning plate 571 is kept at a position away from the top of the photovoltaic panel body 3. Although the rainwater inside the cooling frame 52 stops moving, it still continues to absorb the heat generated by the operation of the photovoltaic panel body 3.

[0062] The diameter of the first hose 572 is greater than the diameter of the second hose 575 , and the water output of the spray pipe 573 is less than the flow rate delivered by the first hose 572 .

[0063] The rainwater sprayed from the spray pipe 573 will be directly discharged after cleaning the surface of the photovoltaic panel body 3, which will cause waste to a certain extent and is contrary to the concept of energy saving.

[0064] When the first hose 572 transports rainwater to the interior of the spray pipe 573, since the amount of rainwater sprayed out of the spray pipe 573 is less than the amount transported by the first hose 572, part of the rainwater flows directly back to the interior of the collecting box 41 through the second hose 575 for collection and recycling, while the rainwater sprayed out of the spray pipe 573 passes through the surface of the photovoltaic panel body 3 and enters the interior of the collecting box 41, thereby fully improving the utilization rate of the rainwater inside the collecting box 41.

[0065] Instructions for use: In rainy weather, the collection box 41 can collect rainwater on the surface of the photovoltaic panel body 3. As the water level rises, the foam float 48 can block the entrance between the two trapezoidal guide blocks 47, slowing down the evaporation rate of rainwater in the collection box 41. After the rainwater in the collection box 41 is collected, the L-shaped moving plate 438 contacts the control switch 436 above, and the electric slide rail 439 is turned on to work. The slide plate 435 is moved to cover the sunshade cloth 4311 on the mesh plate 44, effectively avoiding direct sunlight from shining into the collection box 41 and reducing the internal temperature of the collection box 41. When the sunshade cloth 4311 is recovered, the surface of the sunshade cloth 4311 can be wiped by the wiping component 434, thereby increasing the service life of the sunshade cloth 4311.

[0066] After the photovoltaic panel body 3 has been working for a period of time, the rainwater inside the collection box 41 can be transported to the inside of the cooling frame 52 through the water inlet pipe 54 through the cooperation of the various components of the cooling assembly 5, and the rainwater continuously absorbs the heat inside the photovoltaic panel body 3. After absorbing the heat, part of the water passes through the first hose 572, the spray pipe 573 and the second hose 575 in sequence, and finally enters the inside of the collection box 41, continuously replenishing the inside of the cooling frame 52 with low-temperature moisture, while the other part of the rainwater is sprayed out through the spray pipe 573 to wipe the surface of the photovoltaic panel body 3 and cool the surface of the photovoltaic panel body 3, thereby avoiding the influence of temperature on the power generation efficiency of the photovoltaic panel body 3. At the same time, the cleaned rainwater passes through the mesh plate 44 and enters the inside of the collection box 41 again, thereby improving the utilization rate of rainwater.

[0067] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
