Description

Technical Field

[0001] The invention belongs to the technical field of solar cells, and in particular relates to a solar panel maintenance device and a maintenance method. Background Art

[0002] Solar panels are an important part of the development of new energy. They use sunlight to generate electricity and are a clean, renewable way of using energy. Against the backdrop of increasingly serious global climate change and environmental problems, solar panels are increasingly being used and have become an important force in the field of new energy. Cleaning solar panels is an important part of ensuring their efficient operation and extending their service life. In harsh environments, in order to prevent damage to solar panels, it is also very important to store and maintain solar panels.

[0003] Therefore, it is necessary to design a device that can store, maintain and clean solar panels. Summary of the invention

[0004] The invention discloses a solar panel maintenance device and a maintenance method, which are intended to solve the technical problem that the existing device cannot well store, maintain and clean the solar panel.

[0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A solar panel maintenance device includes a storage box, a bracket, a moving component and a cleaning component;

[0007] A connecting rod is provided on the inner wall of the storage box, the bracket is sleeved on the connecting rod and is rotatably connected to the connecting rod, the bracket can be adjusted in inclination after being pulled out, and the side wall of the bracket can be fixedly matched with the side wall of the storage box after the bracket is pulled out;

[0008] The moving component is arranged inside the storage box, the cleaning component is arranged between the moving component and the bracket, and the cleaning component is connected to the moving component;

[0009] The cleaning assembly includes a scraping part, a brushing part and a water washing part. The brushing part includes a first cleaning member and a second cleaning member. The water washing part is connected to the scraping part. The solar panel is cleaned by the scraping part, the brushing part and the water washing part.

[0010] After adopting this technical method, it should be noted that the connecting rod is fixedly connected to the inner wall of the storage box. When the bracket is pulled out, the connecting rod can provide certain support for the bracket. When the bracket needs to be stored due to the influence of the external environment or other factors, the bracket is adjusted to a vertical state and pushed horizontally into the storage box, saving the space occupied by the overall device; after the storage is completed, the solar panel can be cleaned. According to the actual situation of the solar panel, the cleaning component can be controlled to move back and forth along the moving component for repeated cleaning. In the present invention, the cleaning component can achieve three cleaning modes and three-level cleaning effects. The three cleaning modes are scraping, brushing and washing, and the three-level cleaning effect is achieved through the three cleaning modes, and finally the solar panel can be completely cleaned when the solar panel is stored.

[0011] Furthermore, the cleaning component includes a shell, a groove is provided on a side of the shell away from the movable component, a connecting plate is provided in the groove, a plurality of elastic members are provided between the connecting plate and the groove, the first cleaning member and the second cleaning member are provided in sequence on a side of the connecting plate away from the movable component, the scraping part is provided on a side of the shell close to the first cleaning member, the scraping part includes a scraping bar, and the scraping bar is inclined toward the bracket side.

[0012] After adopting this technical method, it should be noted that the scraper bar is made of rubber material, the first cleaning member is made of hard brush material, and the second cleaning member is made of sponge material. In the present invention, when the elastic member is in a free state, the front end of the scraper bar will be in close contact with the surface of the solar panel. Since the scraper bar is made of rubber material, it can effectively scrape out most of the dust or smaller impurities. After the scraper bar scrapes, the first cleaning member will brush away the impurities that the scraper bar has not scraped away, and finally the second cleaning member will perform further brushing. On the one hand, the elastic member makes the scraper bar close to the solar panel. On the other hand, when there are larger impurities on the solar panel and the scraper bar is difficult to scrape away, in order to protect the solar panel, the elastic member can shrink when the scraper bar is scraping, so that the scraper bar passes over the impurities to prevent scratches on the solar panel.

[0013] Furthermore, the water washing part includes a water chamber, which is arranged inside the shell, and the side of the water chamber close to the scraper is connected to the outside world, and the side of the water chamber close to the second cleaning member is connected to the outside world. The lower end of the water chamber is connected to a pipe, and one end of the pipe is connected to a water tank through a water pump.

[0014] After adopting this technical method, it should be noted that the water tank is located inside the storage box, and a water inlet pipe is connected to the water tank, which passes through the storage box to connect to the external water source. When the water pump pumps the water in the water tank into the outer shell, the water will flow out from the scraping bar and the outer shell near the second cleaning part through the water tank. Therefore, when the scraping bar is scraping, the water flow will soften the impurities, making it easier for the scraping bar to scrape. After the second cleaning part completes the final brushing, the water flows out for further cleaning.

[0015] Preferably, when the bracket is in the storage state, the distance between the end of the scraper strip and the bracket and the distance between the first cleaning member and the second cleaning member and the bracket decrease successively.

[0016] After adopting this technical method, it should be noted that, because the scraper strip will be close to the solar panel under the action of the elastic member, and in order to make the cleaning effect of the first cleaning member and the second cleaning member better, the distance between the first cleaning member and the second cleaning member and the bracket is smaller than the distance between the scraper strip and the bracket, so that the first cleaning member and the second cleaning member have a certain pressure on the solar panel, which is convenient for brushing.

[0017] Furthermore, the moving component includes a driving motor, the output end of the driving motor is connected to a screw, the screw is laterally arranged inside the storage box, and the end of the screw is rotatably connected to the inner wall of the storage box, a guide rod is provided below the screw, a slider is connected to the screw and the guide rod, the side wall of the slider is connected to the outer shell, and the outer wall of the storage box is provided with control buttons to respectively control the water pump and the driving motor.

[0018] After adopting this technical method, it should be noted that the guide rod is arranged directly below the screw rod, and the surface of the guide rod is smooth. A threaded hole and a through hole are provided on the slider, and the threaded hole and the through hole are respectively matched with the screw rod and the guide rod. Under the limitation of the guide rod, the rotation of the screw rod will drive the slider to move, thereby driving the cleaning component to follow the movement, so as to realize the cleaning component moving along the solar panel for cleaning; the control button is electrically connected to the water pump and the drive motor respectively.

[0019] Preferably, a movable rod is connected between the connecting rod and the bracket, and a first limiting ring and a second limiting ring are respectively provided at both ends of the movable rod. The first limiting ring is slidably placed inside the connecting rod, and the second limiting ring is slidably placed inside the bracket.

[0020] After adopting this technical method, it should be noted that since the bracket needs to be stretched outward for an additional distance during the unfolding process in order to cooperate with the side wall of the storage box when rotating, in order to further enhance the stability of the bracket, a movable rod is set between the bracket and the connecting rod, and the first limiting ring and the second limiting ring are set to prevent the movable rod from being pulled off. Therefore, when the bracket is pulled out or the bracket is pushed into the storage box, the movable rod will slide with it, and after the bracket is pulled out, the movable rod will provide support to increase strength.

[0021] Preferably, the bracket includes a first bracket and a second bracket, two movable components are provided in the storage box, driving motors of the two movable components are arranged on the left and right inner walls of the storage box, and the two movable components are connected to the cleaning device through the slider.

[0022] After adopting this technical solution, it should be noted that the first bracket and the second bracket are pulled out from the right end and the left end of the storage box respectively, and are pushed to the left end and the right end of the storage box respectively when stored, and the driving motor of the moving component corresponding to the first bracket is located on the inner wall of the left end of the storage box, and the driving motor of the moving component corresponding to the second bracket is located on the inner wall of the right end of the storage box. Therefore, the present invention can choose to connect two solar photovoltaic panels to improve the power generation efficiency.

[0023] Furthermore, the left and right sides of the storage box are respectively provided with a first limiting groove and a second limiting groove, the side walls of the first bracket and the second bracket are correspondingly provided with limiting blocks, the first limiting groove and the second limiting groove are provided with a plurality of limiting holes, the limiting blocks are provided with bolts, and the bolts cooperate with the limiting holes for limiting.

[0024] After adopting this technical solution, it should be noted that when the first bracket and the second bracket are moved to the corresponding positions of the first limit groove and the second limit groove, different bracket inclination angles can be adjusted by cooperating with different limit holes to improve the power generation efficiency of the solar panel.

[0025] Furthermore, two guide grooves are transversely provided on the inner bottom surface of the storage box, and the bracket is slidably matched with the guide grooves.

[0026] After adopting this technical solution, it should be noted that the guide groove can cooperate with the bracket to keep the bracket stable when stored, and keep the solar panel stable without shaking when cleaning.

[0027] Preferably, a collecting groove is further provided inside the storage box, and the collecting groove is located at the lower end of the cleaning device. The collecting groove can collect dust and sewage brushed by the cleaning device, and the collecting groove can be pulled out for cleaning later.

[0028] Preferably, the control button includes a drive motor start / stop button, a water pump start / stop button and a drive motor control button; the drive motor start / stop button and the water pump start / stop button are electrically connected to the drive motor and the water pump, respectively; and the drive motor control button is electrically connected to the drive motor and controls the forward and reverse rotation of the drive motor.

[0029] Preferably, the connecting rod is an electric push rod, the telescopic end of the electric push rod is connected to the bracket, and the other end is connected to a reduction motor. An angle sensor is provided on the output shaft of the reduction motor, a displacement sensor is provided on the outer shell, and a processing unit is also provided inside the storage box. The angle sensor, the electric push rod and the displacement sensor are all electrically connected to the processing unit.

[0030] Preferably, the storage box is also provided with a meteorological sensor and / or a light sensor and / or a clock module, and the meteorological sensor, the light sensor and the clock module are electrically connected to the processing unit respectively.

[0031] After adopting this technical solution, it should be noted that the drive motor, water pump, clock module and sensors are electrically connected to the processing unit respectively, and the drive motor, water pump, reduction motor, electric push rod, sensors, clock module and processing unit are all connected to an external power supply; the meteorological sensor is used to sense the external weather and transmit the weather information to the processing unit for processing, the light sensor is used to sense the external light conditions and transmit the light information to the processing unit for processing, the clock module is used to transmit time information to the sensor, the meteorological sensor and the light sensor are both arranged at the upper end of the storage box to improve the detection accuracy, and the clock module, meteorological sensor and the light sensor are all prior art;

[0032] After adopting this scheme, when the meteorological sensor detects abnormal external weather, the processing unit can control the reduction motor and the electric push rod to start and store the bracket. Conversely, when the meteorological sensor detects that the external weather is normal, the processing unit controls the bracket to unfold. When the light sensor detects that the external light is weak, the processing unit controls the reduction motor and the electric push rod to start and store the bracket. Conversely, when the light sensor detects that the external light is strong, the processing unit controls the bracket to unfold. The clock module can also be used to enable the processing unit to control the reduction motor and the electric push rod at a fixed time to store or unfold the bracket.

[0033] A solar panel maintenance method comprises the following steps:

[0034] S1. Storage of solar panels

[0035] When the solar panel needs to be stored, the bracket is rotated until the bracket can be matched with the corresponding guide groove, and the bracket is retracted inward until the bracket is retracted to the innermost end to complete the storage;

[0036] S2. Solar panel cleaning

[0037] First, the water pump is started, and the water is sent into the housing by the water pump, and flows out through the connection between the water cavity and the outside. After 5 seconds, the driving motor is started, and the driving motor drives the screw to rotate. Under the action of the guide rod and the screw, the slider drives the cleaning component to move, and the scraper, the first cleaning component and the second cleaning component cooperate with the water pump to clean;

[0038] S3, Secondary cleaning

[0039] The driving motor is controlled to reverse, and the second cleaning member and the first cleaning member will brush the solar panel in turn, and water will flow out from both ends of the water chamber for flushing;

[0040] S4, Solar Panel Unfolding

[0041] Extend the bracket, then rotate the bracket and adjust it to a suitable angle.

[0042] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0043] 1. A solar panel maintenance device and maintenance method provided by the present invention can vertically store the bracket by setting a connecting rod sleeved on the bracket, thereby reducing the space occupied by the device, and adjusting the inclination angle by cooperating between the bracket and the outer wall of the storage box;

[0044] 2. A solar panel maintenance device and maintenance method provided by the present invention can realize three cleaning modes and three-level cleaning effects by setting a scraper bar, a first cleaning member and a second cleaning member in cooperation with a water pump. The three cleaning modes are scraping, brushing and washing, and the three-level cleaning effects are achieved through the three cleaning modes, and finally the solar panel can be completely cleaned when the solar panel is stored;

[0045] 3. The present invention provides a solar panel maintenance device and maintenance method, by setting the distance between the first cleaning member and the second cleaning member and the bracket to be smaller than the distance between the scraper and the bracket, so that the first cleaning member and the second cleaning member have a certain pressure on the solar panel, which is convenient for brushing.

The clock module 25 can also be used to enable the processing unit 21 to control the reduction motor 20 and the electric push rod at a fixed time to retract or unfold the bracket.

[0093] In this embodiment, the angle sensor is used to detect the rotation angle of the output shaft of the reduction motor 20. When the bracket is in a vertical state, the processing unit 21 first controls the reduction motor 20 to stop, and then controls the electric push rod to retract, driving the bracket to retract into the storage box 1. When the electric push rod is fully retracted, the processing unit 21 controls the electric push rod to stop, and controls the drive motor 201 and the water pump 16 to start, so as to clean the solar panel. The displacement sensor 22 is used to detect the moving distance of the cleaning component 3. When the displacement sensor 22 detects that the displacement length of the cleaning component 3 is consistent with the length of the bracket, the processing unit 21 controls the drive motor 201 to reverse or stop.

[0098] S2. Solar panel cleaning

[0099] First, press the water pump start / stop button 1202 to start the water pump 16. The water pump 16 delivers water into the housing 301 and flows out through the water cavity 307 where it is connected to the outside. After 5 seconds, press the drive motor start / stop button 1201 to start the drive motor 201. The drive motor 201 drives the screw 202 to rotate. Under the action of the guide rod 203 and the screw 202, the slider 204 drives the cleaning component 3 to move. The scraper bar 304, the first cleaning component 3 and the second cleaning component 3 cooperate with the water pump 16 to clean.

[0100] S3, Secondary cleaning

[0101] Press the drive motor control button 1203 to control the drive motor 201 to reverse, and the second cleaning member 306 and the first cleaning member 305 will brush the solar panel in turn, and water will flow out from both ends of the water chamber 307 for flushing;

[0102] S4, Solar Panel Unfolding

[0103] Pull out the bracket until the limit block 7 is pulled out of the storage box 1, rotate the bracket to make the limit block 7 cooperate with the corresponding first limit groove 10 or second limit groove 11, adjust to a suitable angle, and tighten the bolt 18 to fix the bracket.

[0104] Example 8

[0105] The difference between this embodiment and embodiment 7 is that the following steps are included:

[0106] S1. Storage of solar panels

[0107] S1.1. Power on

[0108] Press the main power button to power on the drive motor 201, the water pump 16, the reduction motor 20, the electric push rod, the sensors, the clock module 25 and the processing unit 21.

[0109] S1.2. Determine storage conditions

[0110] When the meteorological sensor 23 detects abnormal external weather, such as rain or snow, the processing unit 21 can control the reduction motor 20 and the electric push rod to start and store the bracket. On the contrary, when the meteorological sensor 23 detects that the external weather is normal, the processing unit 21 controls the bracket to unfold. When the light sensor 24 detects that the external light is weak, the processing unit 21 controls the reduction motor 20 and the electric push rod to start and store the bracket. On the contrary, when the light sensor 24 detects that the external light is strong, the processing unit 21 controls the bracket to unfold. The clock module 25 can also be used to control the reduction motor 20 and the electric push rod at a fixed time to store or unfold the bracket. For example, the clock module 25 sends a signal to the processing unit 21 at 7 o'clock every evening, and the processing unit 21 controls the bracket to be stored.

[0111] In step S1.2, the light sensor 24 and the clock module 25 jointly determine the storage condition: when the clock module 25 does not reach the fixed setting time, if the light sensor 24 detects that the external light is weak, the processing unit 21 controls the reduction motor 20 and the electric push rod to store the bracket;

[0112] In step S1.2, the weather sensor 23 and the clock module 25 jointly determine the storage conditions: when the clock module 25 does not reach the fixed setting time, if the weather sensor 23 detects abnormal external weather, such as rain, snow and other severe natural weather, the processing unit 21 controls the reduction motor 20 and the electric push rod to store the bracket;

[0113] In step S1.2, the light sensor 24 and the meteorological sensor 23 jointly determine the storage condition: when the light sensor 24 detects that the external light is normal, if the meteorological sensor 23 detects that the external climate is abnormal, such as sudden severe convective weather causing hail, the processing unit 21 controls the reduction motor 20 and the electric push rod to store the bracket;

[0114] In step S1.2, the meteorological sensor 23, the light sensor 24 and the clock module 25 jointly determine the storage conditions: when the clock module 25 has not reached the set time, the meteorological sensor 23 detects abnormal weather or the light sensor 24 detects weak light, the processing unit 21 can control the reduction motor 20 and the electric push rod to store the bracket.

[0115] In step S1.2, when the bracket is stored, the processing unit 21 first controls the reduction motor 20 to start and rotate the bracket until the angle sensor detects that the bracket rotates to a vertical state. At this time, the processing unit 21 controls the reduction motor 20 to stop, and then the processing unit 21 controls the electric push rod to retract until the electric push rod is fully retracted, and the processing unit 21 controls the electric push rod to stop.

[0116] S2. Solar panel cleaning

[0117] When the electric push rod is fully retracted, the electric push rod transmits the retraction data to the processing unit 21. The processing unit 21 first controls the water pump 16 to start. The water pump 16 sends water into the housing 301 and flows out through the water cavity 307 connected to the outside. After an interval of 5 seconds, when the water cavity 307 is filled with water, the processing unit 21 controls the drive motor 201 to start. The drive motor 201 drives the screw 202 to rotate. Under the action of the guide rod 203 and the screw 202, the slider 204 drives the cleaning component 3 to move. The scraper 304, the first cleaning component 3 and the second cleaning component 3 cooperate with the water pump 16 to clean. During the cleaning, the displacement sensor 22 measures the displacement of the cleaning component 3.

[0118] In step S2, it also includes the conditions for determining whether to perform cleaning: the clock module 25 transmits instructions to the processing unit 21 at a specified time period, such as every 3 days or every week, and the processing unit 21 controls the drive motor 201 and the water pump 16 to clean the solar panel at a specified time point.

[0119] S3, Secondary cleaning

[0120] When the displacement sensor 22 detects that the displacement of the cleaning component 3 is consistent with the length of the bracket, the processing unit 21 controls the driving motor 201 to rotate in the opposite direction, and the cleaning component 3 will move in the opposite direction, thereby driving the second cleaning member 306 and the first cleaning member 305 to brush the solar panel in sequence, and at the same time, water flows out from both ends of the water cavity 307 for flushing, until the displacement sensor 22 detects that the displacement length of the cleaning component 3 is consistent with the length of the bracket again, and the processing unit 21 controls the driving motor 201 to stop;

[0121] S4, Solar Panel Unfolding

[0122] When the bracket deployment condition is met, the processing unit 21 controls the electric push rod to extend, and after the electric push rod is fully extended, the electric push rod transmits data to the processing unit 21, and the processing unit 21 controls the electric push rod to stop, and then the control unit controls the reduction motor 20 to start, and controls the rotation angle of the reduction motor 20 by setting the detection angle of the angle sensor in advance. When the bracket rotates to the preset position of the angle sensor, the processing unit 21 controls the reduction motor 20 to stop;

[0123] In step S4, the deployment condition includes: determining whether the deployment condition is met by the clock module 25 or the meteorological sensor 23 or the light sensor 24 alone, determining whether the deployment condition is met by the clock module 25, the meteorological sensor 23 and the light sensor 24 in pairs, and determining whether the deployment condition is met by the clock module 25, the meteorological sensor 23 and the light sensor 24 together;

[0124] When the meteorological sensor 23, the light sensor 24, or the clock module 25 is used to determine whether the deployment conditions are met, when the meteorological sensor 23 detects that the external weather is normal, the processing unit 21 first controls the electric push rod to extend, and then controls the reduction motor 20 to rotate, until it rotates to the preset position of the angle sensor and then the processing unit 21 controls the reduction motor 20 to stop; when the light sensor 24 detects that the external light is normal, the processing unit 21 first controls the electric push rod to extend, and then controls the reduction motor 20 to rotate, until it rotates to the preset position of the angle sensor and then the processing unit 21 controls the reduction motor 20 to stop; when the clock module 25 sends a signal to the processing unit 21 at a preset time point, such as 6 o'clock every morning, the processing unit 21 first controls the electric push rod to extend, and then controls the reduction motor 20 to rotate, until it rotates to the preset position of the angle sensor and then the processing unit 21 controls the reduction motor 20 to stop.

[0125] When the clock module 25, the meteorological sensor 23 and the light sensor 24 are combined in pairs to jointly determine whether the deployment conditions are met, the clock module 25 is at a preset time point. At this time, when the meteorological sensor 23 or the light sensor 24 detects that the weather is normal or the light is normal, the processing unit 21 first controls the electric push rod to extend, and then controls the reduction motor 20 to rotate. After it rotates to the preset position of the angle sensor, the processing unit 21 controls the reduction motor 20 to stop; when the meteorological sensor 23 and the light sensor 24 are combined to determine whether the deployment conditions are met, both need to determine that the conditions are normal at the same time, and then the processing unit 21 controls the electric push rod and the reduction motor 20 to start to deploy the bracket.

[0126] When the clock module 25, the meteorological sensor 23 and the light sensor 24 jointly determine whether the deployment conditions are met, when the clock module 25 is at the preset time point, the meteorological sensor 23 and the light sensor 24 jointly determine whether the weather and light are normal. If normal, the processing unit 21 first controls the electric push rod to extend, and then controls the reduction motor 20 to rotate, until it rotates to the preset position of the angle sensor, and then the processing unit 21 controls the reduction motor 20 to stop.
