Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a solar street lamp that facilitates cleaning of solar panels. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, use maintenance-free valve-controlled sealed batteries (gel batteries) to store electrical energy, use ultra-bright LED lamps as light sources, and are controlled by intelligent charge and discharge controllers to replace traditional public electric lighting street lights.

[0003] During the use of solar street lights, the solar panels will be covered with dust and form a dust layer. The dust layer will block the sunlight and reduce the amount of solar radiation received by the solar panels. Therefore, the dust layer on the solar panels needs to be cleaned. The dust layer on existing solar panels is usually cleaned manually on a regular basis. However, the time when the dust layer is formed, which seriously affects the thickness of the solar panel power generation, is accidental and uncertain. Therefore, it is difficult to clean the dust layer in time by regular cleaning, resulting in inconvenience in the use of solar street lights. Summary of the invention

[0004] In order to improve the problem that it is difficult to clean the dust layer in time by regular cleaning, resulting in inconvenience in using solar street lights, the present application provides a solar street light that is easy to clean the solar panel.

[0005] The present application provides a solar street light that is easy to clean solar panels and adopts the following technical solutions: A solar street light for facilitating cleaning of solar panels, comprising a lamp frame, a solar panel and a lamp module arranged on the lamp frame, wherein the lamp frame is provided with a photovoltaic box for placing the solar panel, the photovoltaic box is provided with a light-transmitting plate above the light-receiving side of the solar panel, and the light-transmitting plate and the photovoltaic box can form a closed space; The photovoltaic box is provided with a processing control module, a cleaning unit and two groups of photoresistors, one group of which is arranged inside the photovoltaic box and is used to sense the sunlight passing through the light-transmitting plate, and the other group of which is arranged outside the photovoltaic box and is used to sense external sunlight; The two groups of photoresistors are electrically connected to the processing control module, and the processing control module is used to calculate the difference between the two groups of photoresistors, and when the difference exceeds the allowable value, output a control signal to the cleaning unit to control the cleaning unit to clean the light-transmitting plate.

[0006] By adopting the above technical solution, as the solar panels are used, dust adheres to the light-transmitting plate. As the dust increases, the two groups of photoresistors inside and outside the photovoltaic box feel different sunlight intensities, which is reflected in the resistance difference between the two groups of photoresistors. The processing and control module monitors the difference between the two groups of photoresistors. When the difference exceeds the allowable value, the processing and control module controls the cleaning unit to clean the light-transmitting plate. Compared with the existing regular cleaning method, this solution can clean the light-transmitting plate in time according to the obstruction of light by dust, thereby improving the convenience of using solar lamps.

[0007] In a specific possible implementation manner, the solar panel includes a plurality of photovoltaic panel modules, and the photoresistors located inside the photovoltaic box are a plurality of photoresistors arranged in a dot matrix between the plurality of photovoltaic panel modules.

[0008] By adopting the above technical solution, the photoresistors are arranged in a dot matrix, so that the photoresistors can more accurately reflect the shielding of light by the distribution of dust on the light-transmitting plate.

[0009] In a specific possible implementation scheme, the cleaning unit includes a driving motor, a driving screw and a movable cleaning member. The driving motor is arranged outside the photovoltaic box and is electrically connected to the processing control module. The driving screw is rotatably arranged outside the photovoltaic box and is coaxially fixed with the output shaft of the driving motor. The movable cleaning member can abut against the light-transmitting plate and be threadedly connected to the driving screw. The driving screw can drive the movable cleaning member to slide and clean the light-transmitting plate.

[0010] By adopting the above technical solution, when cleaning dust, the driving motor drives the driving screw to rotate, and the driving screw drives the movable cleaning member abutting against the light-transmitting plate to move, so as to clean the dust on the light-transmitting plate, thereby improving the convenience of dust cleaning.

[0011] In a specific possible implementation scheme, the movable cleaning member includes a support plate and a cleaning plate. The support plate is slidably arranged on the photovoltaic box and is connected to the driving screw through a connecting member. The support plate is provided with an extrusion spring connected to the cleaning plate, and the extrusion spring is used to squeeze the cleaning plate to abut against the light-transmitting plate.

[0012] By adopting the above technical solution, when cleaning dust, the support plate presses the cleaning plate against the light-transmitting plate through the squeezing spring, which can improve the stability of the cleaning plate in cleaning dust.

[0013] In a specific possible implementation manner, there are several cleaning plates, and the several cleaning plates are arranged at intervals along the cleaning direction of the support plate. The extrusion springs correspond to the cleaning plates one by one, and the extrusion force of the extrusion springs on the cleaning plates gradually decreases along the cleaning direction of the support plate.

[0014] By adopting the above technical solution, the cleaning plates can clean the dust in layers by applying different squeezing forces to different cleaning plates through the squeezing springs, thereby improving the cleaning effect of the cleaning plates on the dust.

[0015] In a specific possible implementation scheme, the photovoltaic box is provided with a guide plate, the guide plate is provided with a first guide groove and a second guide groove, and the support plate can slide along the first guide groove and the second guide groove; When the support plate slides in the first guide groove, the cleaning plate abuts against the light-transmitting plate, and when the support plate slides in the second guide groove, the cleaning plate is separated from the light-transmitting plate; The guide plate is provided with a first guide structure for guiding the support plate to slide from the first guide groove into the second guide groove, and the guide plate is provided with a second guide structure for guiding the support plate to slide from the second guide groove into the first guide groove; The connecting member includes a driving block and a connecting rod. The driving block is threadedly sleeved on the driving screw rod. The connecting rod is fixedly arranged on the support plate and passes through the driving block in a direction perpendicular to the light-transmitting plate. The connecting rod is slidably connected to the driving block.

[0016] By adopting the above technical solution, when the cleaning plate is cleaning the dust on the light-transmitting plate, the support plate slides along the first guide groove. When a cleaning process is completed, the driving motor flips over and drives the support plate to return. At this time, the support plate slides into the second guide groove under the guidance of the first guide structure. Therefore, in the return of the support plate, the support plate slides along the second guide groove, so that the cleaning plate is separated from the light-transmitting plate, effectively preventing the dust attached to the cleaning plate from attaching to the cleaned light-transmitting plate again, thereby improving the cleaning effect of the light-transmitting plate; when the support plate completes the return, the second guide structure guides the support plate to slide into the first guide groove, so that the support plate can continuously perform the cleaning process and return operation; when the support plate slides from the first guide groove into the second guide groove or from the second guide groove into the first guide groove, the connecting rod slides along the driving block, thereby adapting to the change of the position of the support plate in the first guide groove and the second guide groove when driving the support plate.

[0017] In a specific implementation scheme, the first guide structure includes a first guide groove and a guide plate, one end of the first guide groove is connected to the first guide groove, and the other end is connected to the second guide groove, and the guide plate is rotatably arranged on the guide plate to block the first guide groove and guide the support plate to slide from the first guide groove into the first guide groove.

[0018] By adopting the above technical solution, when the support plate slides from the first guide groove into the second guide groove, the guide plate blocks the first guide groove, so that the support plate slides into the first guide groove along the guide plate, and then slides into the second guide groove along the first guide groove, thereby improving the convenience of the support plate sliding from the first guide groove into the second guide groove.

[0019] In a specific implementation scheme, the second guide structure includes a second guide groove, one end of the second guide groove is connected to the second guide groove, and the other end is connected to the first guide groove, and the driving block is provided with a guide spring for pushing the support plate to slide from the second guide groove along the second guide groove into the first guide groove.

[0020] By adopting the above technical solution, when the support plate slides from the second guide groove into the first guide groove, the guide spring pushes the support plate to slide along the second guide groove into the first guide groove, thereby improving the convenience of the support plate sliding from the second guide groove into the first guide groove.

[0021] In a specific possible implementation mode, the photovoltaic box is provided with a nozzle for spraying water to clean the cleaning plate.

[0022] By adopting the above technical solution, the cleaning plate is cleaned by a nozzle, and the cleaning effect of the cleaning plate on the light-transmitting plate is improved while ensuring that the cleaning plate is clean.

[0023] In a specific possible implementation manner, the photovoltaic box is provided with a guide surface for guiding the cleaning plate to slide onto the light-transmitting plate.

[0024] By adopting the above technical solution, the cleaning plate is guided by the guide surface to slide onto the light-transmitting plate, so that the edge of the light-transmitting plate can be cleaned, thereby improving the cleanliness of the entire light-transmitting plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. With the use of solar panels, dust adheres to the light-transmitting plate. As the dust increases, the two groups of photoresistors inside and outside the photovoltaic box feel different sunlight intensities, which is reflected in the difference in resistance between the two groups of photoresistors. The processing control module monitors the difference between the two groups of photoresistors. When the difference exceeds the allowable value, the processing control module controls the cleaning unit to clean the light-transmitting plate. Compared with the existing regular cleaning method, this solution can clean the light-transmitting plate in time according to the dust blocking the light, thereby improving the convenience of using solar lamps; 2. When the support plate is in the cleaning process, the support plate slides along the first guide groove and abuts against the light-transmitting plate to clean the dust on the light-transmitting plate. When the support plate is in the return process, the support plate slides along the second guide groove, and the cleaning plate is separated from the light-transmitting plate, effectively preventing the dust attached to the cleaning plate from attaching to the cleaned light-transmitting plate again, thereby improving the cleaning effect of the light-transmitting plate.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a solar street lamp which is convenient for cleaning solar panels.

[0037] Reference Figure 1 , Figure 2 A solar street light that is easy to clean a solar panel includes a lamp frame 1 and a solar panel 2, a lamp module 3, and a photovoltaic box 4 arranged on the lamp frame 1. The lamp module 3 is arranged on the top of the lamp frame 1 and is electrically connected to the solar panel 2. The solar panel 2 converts solar energy into electrical energy for storage during the day, and generates electricity for the lamp module 3 at night to drive the lamp module 3 to emit light. The photovoltaic box 4 is a rectangular box structure with an opening on the top. The solar panel 2 in this embodiment includes a plurality of independent photovoltaic panel modules 21. The photovoltaic panel modules 21 are laid flat in the photovoltaic box 4. The photovoltaic box 4 is inclined with respect to the horizontal plane so that the photovoltaic panel modules 21 can receive the maximum amount of solar radiation. The photovoltaic box 4 is provided with a light-transmitting plate 41 above the light-collecting side of the solar panel 2. The light-transmitting plate 41 is a transparent glass plate. The light-transmitting plate 41 covers the opening of the photovoltaic box 4 and can form a closed space with the photovoltaic box 4, which can effectively prevent dust from entering the photovoltaic box 4.

[0038] Reference Figure 1 , Figure 2The photovoltaic box 4 is provided with a processing control module 42, a cleaning unit 5 and two groups of photoresistors 43, wherein the number of one group of photoresistors 43 is several and they are arranged in a dot matrix between several photovoltaic panel modules 21, so that the photoresistors 43 can more accurately reflect the light blocking caused by the dust distribution on the light-transmitting plate 41. The other group of photoresistors 43 is arranged outside the photovoltaic box 4. When the sunlight irradiates the photoresistors 43, the resistance of the photoresistors 43 will change according to the different light intensity, that is, the stronger the light intensity, the smaller the resistance of the photoresistors 43. As the dust gathers on the light-transmitting plate 41, the light transmittance of the light-transmitting plate 41 will be reduced, resulting in the two groups of photoresistors 43 under the same external lighting conditions. The resistance of the photoresistors 43 in the photovoltaic box 4 is greater than the resistance of the photoresistors 43 outside the photovoltaic box 4, which can avoid the cleaning unit 5 from cleaning the light-transmitting plate 41 by mistake on cloudy days or at night.

[0039] Reference Figure 1 , Figure 2 , the two groups of photoresistors 43 are electrically connected to the processing control module 42. The two groups of photoresistors 43 serve as the input end of the processing control module 42, and input signals to the processing control module 42. Initially, the processing control module 42 sets an allowable value of the resistance difference between the two groups of photoresistors 43. When the resistance difference between the two groups of photoresistors 43 is less than the allowable value, the dust on the light-transmitting plate 41 has little effect on the power generation efficiency of the solar panel 2. When the resistance of the two groups of photoresistors 43 is greater than the allowable value, the dust on the light-transmitting plate 41 has a greater effect on the power generation efficiency of the solar panel 2. The output end of the processing control module 42 is connected to the cleaning unit 5. The cleaning unit 5 serves as the output module of the processing control module 42. When the resistance of the two groups of photoresistors 43 is greater than the allowable value, the processing control module 42 outputs a control signal to control the cleaning unit 5 to clean the light-transmitting plate 41. The processing control module 42 controls the cleaning unit 5 to complete an integer number of finishing processes each time until the difference between the two groups of photoresistors 43 is less than the allowable value.

[0040] As the solar panel 2 is used, dust adheres to the light-transmitting plate 41. As the dust increases, the light transmittance of the light-transmitting plate 41 deteriorates, resulting in different sunlight intensities felt by the two groups of photoresistors 43 inside and outside the photovoltaic box 4. This is reflected in the resistance difference between the two groups of photoresistors 43. The processing and control module 42 monitors the difference between the two groups of photoresistors 43. When the difference exceeds the allowable value, the processing and control module 42 controls the cleaning unit 5 to clean the light-transmitting plate 41. Compared with the existing regular cleaning method, this solution can clean the light-transmitting plate 41 in time according to the obstruction of light by dust, thereby improving the convenience of using the solar lamp.

[0041] Reference Figure 3 , Figure 4Two relatively arranged guide plates 44 are fixedly provided on the end wall on the opening side of the photovoltaic box 4, and are arranged on both sides of the light-transmitting plate 41 along the inclination direction of the photovoltaic box 4. The cleaning unit 5 in this embodiment includes a driving motor 51, a driving screw 52 and a movable cleaning member 53. The driving motor 51 and the driving screw 52 are respectively corresponding to the guide plates 44. The driving screw 52 is rotatably arranged on the guide plate 44 through a rotating seat. The driving motor 51 is fixedly arranged on the guide plate 44. The driving motor 51 is electrically connected to the processing control module 42. The processing control module 42 controls the opening and closing of the driving motor 51 through a control signal. The output shaft of the driving motor 51 is coaxially fixed with the driving screw 52.

[0042] Reference Figure 3 , Figure 4 The movable cleaning member 53 in this embodiment includes a support plate 531 and a cleaning plate 532. The support plate 531 corresponds to the driving screw 52 one by one. Each support plate 531 is connected to the driving screw 52 through a connecting member 533. The connecting member 533 in this embodiment includes a driving block 5331 and a connecting rod 5332. The connecting rod 5332 is fixedly arranged on the support plate 531 along a direction perpendicular to the light-transmitting plate 41. The driving block 5331 is slidably arranged on the top wall of the guide plate 44. The driving screw 52 passes through the driving block 5331 and is threadedly connected to the driving block 5331. The connecting rod 5332 passes through the driving block 5331 and is slidably connected to the driving block 5331.

[0043] Reference Figure 3 , Figure 5 The two cleaning plates 532 are arranged parallel and spaced along a direction perpendicular to the sliding direction of the driving block 5331. Two guide seats 534 are fixedly provided at the bottom of each support plate 531. The guide seats 534 correspond to the cleaning plates 532 one by one. The top of the cleaning plate 532 is inserted into the guide seats 534 and slidably connected with the guide seats 534. The guide seats 534 can limit the separation from the cleaning plate 532. The bottom of the cleaning plate 532 can abut against the light-transmitting plate 41. The bottom of the cleaning plate 532 is made of rubber material, which can reduce the scratch between the cleaning plate 532 and the light-transmitting plate 41.

[0044] Reference Figure 3 , Figure 5Each guide seat 534 is provided with a pressing spring 535, one end of the pressing spring 535 abuts against the support plate 531, and the other end abuts against the top of the cleaning plate 532. The pressing force of the pressing spring 535 on the cleaning plate 532 gradually decreases along the sliding direction of the support plate 531 when cleaning. The pressing force is adjusted by the contraction length of the pressing spring 535 pressing the cleaning plate 532. Due to the different attachment time of dust on the light-transmitting plate 41, the dust attached first has a strong binding effect with the light-transmitting plate 41, and the dust attached later has a poor binding effect with the light-transmitting plate 41. When cleaning the dust on the light-transmitting plate 41, the cleaning plate 532 with a small pressing force cleans the dust with a poor attachment effect on the upper layer, and the cleaning plate 532 with a large pressing force cleans the dust with a strong attachment effect on the lower layer, thereby realizing layered cleaning of dust and improving the cleaning effect of the cleaning plate 532 on dust.

[0045] When cleaning the dust, the driving motor 51 drives the driving screw 52 to rotate, and the driving screw 52 drives the driving block 5331 to slide on the guide plate 44. The driving plate drives the cleaning plate 532 abutting against the light-transmitting plate 41 to slide through the connecting rod 5332 and the support plate 531, thereby cleaning the dust on the light-transmitting plate 41 and improving the convenience of dust cleaning.

[0046] Reference Figure 3 , Figure 4 , the two guide plates 44 are provided with a first guide groove 541 and a second guide groove 542 which are arranged parallel to the light-transmitting plate 41 on opposite sides, the first guide groove 541 and the second guide groove 542 are both longer than the length of the light-transmitting plate 41 in this direction, the second guide groove 542 is arranged above the first guide groove 541, and each support plate 531 is provided with a sliding column 543 which slides in the corresponding first guide groove 541 and the second guide groove 542, and the support plate 531 can slide along the first guide groove 541 and the second guide groove 542.

[0047] Reference Figure 3 When the sliding post 543 slides in the first guide groove 541, the cleaning plate 532 abuts against the light-transmitting plate 41, and when the sliding post 543 slides in the second guide groove 542, the cleaning plate 532 moves upward and separates from the light-transmitting plate 41. The guide plate 44 is provided with a first guide structure 544 for guiding the support plate 531 to slide from the first guide groove 541 into the second guide groove 542, and the guide plate 44 is provided with a second guide structure 545 for guiding the support plate 531 to slide from the second guide groove 542 into the first guide groove 541.

[0048] Reference Figure 3 , Figure 6The first guide structure 544 includes a first guide groove 5441 and a guide plate 5442. One end of the first guide groove 5441 is connected to the first guide groove 541, and the other end is connected to the second guide groove 542. The angle between the first guide groove 5441 and the second guide groove 542 is an obtuse angle, and the angle between the first guide groove 5441 and the first guide groove 541 is an acute angle. The guide plate 5442 is on the guide plate 44 through a rotating shaft 5443. The rotating shaft 5443 is fixedly connected to the guide plate 5442. The rotating shaft 5443 is located at the intersection of the first guide groove 541 and the first guide groove 5441. A torsion spring 5444 is provided on the rotating shaft 5443. One end of the torsion spring 5444 is fixedly connected to the guide plate 44, and the other end is fixedly connected to the guide plate 5442. The torsion spring 5444 applies an elastic force to the guide plate 5442 to rotate toward the first guide groove 541. When the cleaning plate 532 slides away from the light-transmitting plate 41, the sliding column 543 can push the guide plate 5442 to rotate, so that the first guide groove 541 opens. When the sliding column 543 passes over the guide plate 5442, the guide plate 5442 blocks the first guide groove 541 under the push of the torsion spring 5444, so that the sliding column 543 can slide into the first guide groove 5441 along the guide plate 5442 during the return stroke, and then slide into the second guide groove 542 along the first guide groove 5441.

[0049] Reference Figure 3 The second guide structure 545 includes a second guide groove 5451, one end of the second guide groove 5451 is connected to the second guide groove 542, and the other end is connected to the first guide groove 541. The second guide groove 5451 is arranged in a direction perpendicular to the light-transmitting plate 41. A guide spring 546 is sleeved on the connecting rod 5332, one end of the guide spring 546 abuts against the driving block 5331, and the other end abuts against the support plate 531. The guide spring 546 can push the sliding column 543 to slide into the first guide groove 541 along the second guide groove 5451, thereby improving the stability of the sliding column 543 sliding into the first guide groove 541 along the second guide groove 5451.

[0050] When the cleaning plate 532 is cleaning the dust on the light-transmitting plate 41, the sliding column 543 guides the support plate 531 to slide along the first guide groove 541. When a cleaning process is completed, the driving motor 51 reverses and drives the support plate 531 to return, and the sliding column 543 slides from the first guide groove 541 into the second guide groove 542. The torsion spring 5444 pushes the guide plate 5442 to block the first guide groove 541, so that the support plate 531 slides into the first guide groove 5441 along the guide plate 5442, and then slides into the second guide groove 542 along the first guide groove 5441, thereby improving the convenience of the support plate 531 sliding from the first guide groove 541 to the second guide groove 542. During the return stroke of the support plate 531, the support plate 531 slides along the second guide groove 542, so that the cleaning plate 532 is separated from the light-transmitting plate 41, effectively preventing the dust attached to the cleaning plate 532 from attaching to the cleaned light-transmitting plate 41 again, thereby improving the cleaning effect of the light-transmitting plate 41; when the support plate 531 returns to the initial position, the guide spring 546 pushes the sliding column 543 to slide into the first guide groove 541 along the second guide groove 5451, so that the support plate 531 can cycle through the cleaning process and the return stroke operation; when the support plate 531 slides from the first guide groove 541 into the second guide groove 542 or from the second guide groove 542 into the first guide groove 541, the connecting rod 5332 slides along the driving block 5331, so as to adapt to the change of the position of the support plate 531 in the first guide groove 541 and the second guide groove 542 when the support plate 531 is driven.

[0051] Reference Figure 7 , Figure 8 A nozzle 61 is provided on the guide plate 44, and the nozzle 61 corresponds to the cleaning plate 532 one by one. The nozzle 61 is arranged above the highest sliding point of the cleaning plate 532, and each nozzle 61 is provided with a nozzle 62 facing the cleaning plate 532. When the cleaning plate 532 completes the entire cleaning process and returns to the initial position, the nozzle 61 sprays water toward the cleaning plate 532 through the nozzle 62 to clean the cleaning plate 532. While ensuring that the cleaning plate 532 is clean, the cleaning effect of the cleaning plate 532 on the light-transmitting plate 41 is improved.

[0052] Reference Figure 7 , Figure 8 The photovoltaic box 4 is provided with a guide surface 7 for guiding the cleaning plate 532 to slide onto the light-transmitting plate 41. The highest end of the guide surface 7 extends to the light-transmitting plate 41. The guide surface 7 is arranged below the second guide groove 5451. When the sliding column 543 slides into the first guide groove 541 along the second guide groove 5451, both cleaning plates 532 are placed on the guide surface 7, and the squeezing spring 535 is in a free state. By guiding the cleaning plate 532 to slide onto the light-transmitting plate 41 through the guide surface 7, the edge of the light-transmitting plate 41 can be cleaned, thereby improving the cleanliness of the entire light-transmitting plate 41.

[0053] The implementation principle of a solar street light that is easy to clean solar panels in an embodiment of the present application is as follows: as the solar panel 2 is used, dust adheres to the light-transmitting plate 41. As the dust increases, the light transmittance of the light-transmitting plate 41 deteriorates, resulting in different sunlight intensities felt by the two groups of photoresistors 43 inside and outside the photovoltaic box 4, which is reflected in the photoresistors 43 as a resistance difference between the two groups of photoresistors 43. The processing and control module 42 monitors the difference between the two groups of photoresistors 43. When the difference exceeds the allowable value, the processing and control module 42 controls the driving motor 51 to rotate, and the driving motor 51 drives the cleaning plate 532 to slide on the light-transmitting plate 41 to clean the light-transmitting plate 41. Compared with the existing regular cleaning method, this solution can clean the light-transmitting plate 41 in time according to the obstruction of light by dust, thereby improving the convenience of using the solar lamp.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
