[0016] An intelligent cleaning method based on the intelligent cleaning mechanism of the spherical solar power generation device is carried out according to the following steps:

[0017] Step 1: During the day, the single-chip microcomputer chip controls the second rotating mechanism to make the second semicircular orbit track the sun, and at the same time, the single-chip microcomputer chip controls the tracking motor to make the photosensitive plate align with the sun;

[0018] Step 2: The first photoreceptor on the photosensitive plate focuses sunlight and transmits light energy to the first photoelectric conversion module. The first photoelectric conversion module charges the battery on the one hand and transmits the first electric energy information to the single-chip microcomputer chip for recording on the other hand.

[0019] Step 3, while the single-chip microcomputer chip obtains different first electric energy information, it controls the second rotating motor, and by rotating the bracket, the second photoreceptor is rotated out of the controller box to receive direct sunlight, and the light energy is converted into the current second electric energy information through the second photoelectric conversion module to be recorded by the single-chip microcomputer chip. After obtaining the current second electric energy information, the single-chip microcomputer chip controls the second rotating motor to rotate the second photoreceptor back into the controller box;

[0020] Step 4, the single-chip microcomputer chip obtains the current first electric energy information and the current second electric energy information, takes the current second electric energy information as a search condition, finds the corresponding current first electric energy reference value from a set table, and compares them;

[0021] Step 5: If the first electric energy critical value ≤ the current first electric energy information < the current first electric energy reference value, the glass ball or the photosensitive plate is judged to be uncontaminated or slightly contaminated, and no automatic cleaning operation is required at this time; if the first electric energy threshold value ≤ the current first electric energy information < the first electric energy critical value, the glass ball or the photosensitive plate is judged to be slightly contaminated, and step 6 is executed; if the current first electric energy information < the first electric energy threshold value, the glass ball or the photosensitive plate is judged to be heavily contaminated, and step 7 is executed;

[0022] Step 6, when light pollution occurs, every other night of the week, the single-chip microcomputer chip controls the first rotating mechanism to rotate 360 ​​degrees around the glass ball, and at the same time controls the water inlet pipe solenoid valve to make multiple first nozzles spray cleaning liquid to the outer surface of the glass ball, and the brush on the first semicircular track and the first scraper simultaneously perform circumferential cleaning on the outer surface of the glass ball without dead angles; the single-chip microcomputer chip controls the first rotating motor and the soft water pipe solenoid valve to make the second nozzle spray cleaning liquid to the photosensitive plate, and the two second scrapers perform alternate cleaning on the surface of the first photoreceptor;

[0023] Step 7, after the cleaning is completed, the single-chip microcomputer chip controls the second rotating mechanism to stop the second semicircular track near the bottom of the circular floating platform on one side of the glass ball; the single-chip microcomputer chip controls the first rotating mechanism to make the first semicircular track swing up and down around the circular floating platform on the other side of the glass ball, and at the same time controls the water inlet pipe solenoid valve to make multiple first nozzles spray clean water to the circular floating platform, and the brush and the first scraper are soaked in clean water and scraped by the circular floating platform to throw out the pollutants;

[0025] Step 9, after the single-chip microcomputer chip obtains the current first power information, if the current first power information does not change, there is no need to collect the current second power information; if the current first power information changes, the current first power information is recorded, and the current second power information is collected accordingly, and steps 3 to 8 are executed; if there is no first power information at present, it means that there is no sunlight, and there is no need to collect the current second power information;

[0026] Step 10, the MCU chip transmits the power generation information and electric energy information to the remote terminal through the power grid or wireless network. The technicians can obtain the power generation information and electric energy information from the remote terminal through the mobile phone APP, conduct manual intervention, and command the MCU chip at any time to perform cleaning operations.

[0027] In summary, the technical solution of the present invention has the following beneficial effects:

[0028] This solution solves the problem that the existing spherical solar power generation devices have no automatic cleaning function and need to be cleaned manually, which is difficult to clean and has a high risk factor, low work efficiency, high labor cost, and no intelligent pollution identification capability, making it difficult to clean in time and difficult to judge when to clean best. This solution has the ability to intelligently analyze the degree of pollution on the surface of the glass ball and the photosensitive plate. When there is light pollution, it can be automatically cleaned once a week at night. When there is heavy pollution, it can be automatically cleaned at night on the same day.

The brush 10 and the first scraping strip 11 are attached to the outer surface of the glass ball 1. The first semicircular track 3 is elastic.

[0041] The glass ball 1 is provided with a circular floating platform 5 along the horizontal plane, and the brush 10 and the first scraper strip 11 can pass over the circular floating platform 5.

[0042] The tracking photosensitive mechanism includes a photosensitive plate 16 equipped with a first photoreceptor 15. A tracking motor 17 is provided on one side of the photosensitive plate 16. The tracking motor 17 is rotationally connected to a sliding gear on the photosensitive plate 16.

The controller box 7 controls the clean water source and the cleaning liquid tank through electromagnetic valves (not shown in the figure).

[0045] An intelligent cleaning method based on the intelligent cleaning mechanism of the spherical solar power generation device is carried out according to the following steps:

[0046] Step 1, during the day, the single-chip microcomputer chip 32 controls the second rotating mechanism 31 to make the second semicircular track 4 track the sun, and at the same time, the single-chip microcomputer chip 32 controls the tracking motor 17 to make the photosensitive plate 16 align with the sun;

[0047] Step 2, the first photoreceptor 15 on the photosensitive plate 16 focuses the sunlight and transmits the light energy to the first photoelectric conversion module 33. The first photoelectric conversion module 33 charges the battery 34 on the one hand, and transmits the first electric energy information to the single-chip microcomputer chip 32 for recording on the other hand;

[0048] Step 3, the single-chip microcomputer chip 32 obtains different first electric energy information and controls the second rotating motor 26, and rotates the bracket 28 to rotate the second photoreceptor 27 out of the controller box 7 to receive direct sunlight, and converts the light energy through the second photoelectric conversion module 35 into the current second electric energy information for the single-chip microcomputer chip 32 to record. After obtaining the current second electric energy information, the single-chip microcomputer chip 32 controls the second rotating motor 26 to rotate the second photoreceptor 27 back into the controller box 7;

[0049] Step 4, the single-chip microcomputer chip 32 obtains the current first power information and the current second power information, takes the current second power information as a search condition, finds the corresponding current first power reference value from the set table, and compares them;

[0050] Step 5: If the first electric energy critical value ≤ the current first electric energy information < the current first electric energy reference value, the glass ball 1 or the photosensitive plate 16 is judged to be uncontaminated or slightly contaminated, and no automatic cleaning operation is required at this time; if the first electric energy threshold value ≤ the current first electric energy information < the first electric energy critical value, the glass ball 1 or the photosensitive plate 16 is judged to be slightly contaminated, and step 6 is executed; if the current first electric energy information < the first electric energy threshold value, the glass ball 1 or the photosensitive plate 16 is judged to be heavily contaminated, and step 8 is executed;

[0051] Step 6, when light pollution occurs, every other night of the week, the single chip microcomputer chip 32 controls the first rotating mechanism 30 to rotate 360 ​​degrees around the glass ball 1, and controls the electromagnetic valve of the water inlet pipe 25, so that the multiple first nozzles 29 spray cleaning liquid onto the outer surface of the glass ball 1, and the brush 10 and the first scraper 11 on the first semicircular track 3 simultaneously perform circumferential cleaning of the outer surface of the glass ball 1 without dead angles (the number of circumferential circles is determined by the single chip microcomputer chip according to the degree of pollution); the single chip microcomputer chip 32 controls the first rotating motor 20 and the electromagnetic valve of the soft water pipe 22, so that the second nozzle 21 sprays cleaning liquid onto the photosensitive plate 16, and the two second scrapers 19 perform alternate cleaning of the surface of the first photoreceptor 15;

[0052] Step 7, after the cleaning is completed, the single-chip microcomputer chip 32 controls the second rotating mechanism 31 to stop the second semicircular track 4 near the bottom of the circular floating platform 5 on one side of the glass ball 1; the single-chip microcomputer chip 32 controls the first rotating mechanism 30 to make the first semicircular track 3 swing up and down around the circular floating platform 5 on the other side of the glass ball 1, and at the same time controls the electromagnetic valve of the water inlet pipe 25 to make the multiple first nozzles 29 spray clean water to the circular floating platform 5, and the brush 10 and the first scraper 11 are soaked in clean water and scraped by the circular floating platform 5 to throw out the pollutants;

[0053] Step 8: When severe contamination occurs, the glass ball 1 and the photosensitive plate 16 are automatically cleaned in the evening according to the method of steps 6 to 7;

[0054] Step 9, after the single-chip microcomputer chip obtains the current first power information, if the current first power information does not change, there is no need to collect the current second power information; if the current first power information changes, the current first power information is recorded, and the current second power information is collected accordingly, and steps 3 to 8 are executed; if there is no first power information at present, it means that there is no sunlight, and there is no need to collect the current second power information;

[0055] Step 10, the single-chip microcomputer chip 32 transmits the power generation information (including the duration, strength, power generation, etc. of receiving sunlight) and the electric energy information (power generation efficiency, pollution level) to the remote terminal 36 through the power grid or wireless network. The technicians can obtain the power generation information and electric energy information from the remote terminal 36 through the mobile phone APP, conduct manual intervention, and command the single-chip microcomputer chip 32 at any time to perform cleaning operations. In addition, the patented technicians can also obtain the operating status, automatic cleaning records, various data records and other parameters of the power generation device from the remote terminal 36 through the mobile phone APP, such as whether the cleaning fluid is used up, whether the equipment has a fault, etc., to facilitate remote daily maintenance of the power generation device. As a user, you can install the APP according to actual needs, or not install it, and it will not affect the intelligent analysis and automatic cleaning functions of this solution. The remote terminal 36 is set at the control end of the power supply bureau.

[0056] The first electric energy threshold of this scheme is taken in the following way: the power generation efficiency at this time is seriously low, and the value of the electric energy loss caused by the power generation efficiency is equal to the cost of cleaning the glass ball and the surface of the photosensitive plate at this time (including the cleaning liquid, water, electricity costs and the mechanical loss of the cleaning mechanism, glass ball and photosensitive plate). When the current first electric energy information is greater than the first electric energy critical value, it is judged that the glass ball or the photosensitive plate is basically uncontaminated, and no automatic cleaning operation is required at this time. When the current first electric energy information is equal to the first electric energy critical value, it is judged that the glass ball or the photosensitive plate is in a critical state. At this time, an automatic cleaning operation is taken, and the cost of cleaning the glass ball and the surface of the photosensitive plate is just equal to the newly added power generation value after cleaning. As the current first electric energy information gradually decreases, when the first electric energy threshold ≤ the current first electric energy information < the first electric energy critical value, the power generation efficiency gradually decreases. At this time, an automatic cleaning operation is taken, and the cost of cleaning the glass ball and the surface of the photosensitive plate will be exchanged for an additional power generation value greater than the cost. The unique rotating sunlight detection mechanism design of the present solution effectively protects the second photoreceptor 27 from various external pollutions, thereby ensuring that the detected sunlight energy value is accurate.

[0057] In summary, the technical solution of the present invention has the following beneficial effects:

[0058] This solution solves the existing spherical solar power generation device, which has no automatic cleaning function and needs manual cleaning, which is difficult to clean, has a high risk factor, low work efficiency, high labor cost, and no intelligent pollution identification capability, making it difficult to clean in time and difficult to judge when to clean best. This solution has the ability to intelligently analyze the pollution degree of the glass ball 1 and the photosensitive plate 16. When it is slightly polluted, it can be automatically cleaned once a week at night. When it is heavily polluted, it can be automatically cleaned at night on the same day. In addition, through the mobile phone APP, the pollution situation (pollution degree analysis based on electric energy information) can be grasped at any time, and manual intervention can be performed for cleaning. Compared with the existing technology, this solution saves the cost of manual cleaning, and there is no danger problem for operators. Without manual participation, it intelligently analyzes the pollution degree of the power generation device and automatically cleans it, which improves the cleanliness of the glass ball 1 and the photosensitive plate 16, maximizes the light energy obtained, and maximizes the efficiency of power generation, achieves the best cleaning benefits, and stabilizes the power output of the power generation device.

[0059] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
