[0001] The invention relates to the technical field of solar heat collection, in particular to a solar heat collection system with self-cleaning and monitoring functions. Background Art

[0002] A solar collector is a device that converts the sun's radiation into heat. Since solar energy is relatively scattered, it must be concentrated. Therefore, the collector is a key part of various solar energy devices. Generally, solar collectors are fixedly installed outdoors, but there is a lot of dust in the outdoor air. This dust will fall on the solar collector, blocking the sunlight to a certain extent, thereby affecting the heat collection effect of the sunlight. Usually, the operator needs to clean the surface of the solar collector regularly, which increases the workload of the operator. The cleaning process is time-consuming and laborious. In addition, the operator needs to check the amount of dust on the solar collector from time to time to ensure that the solar collector can efficiently utilize sunlight. Summary of the invention

[0023] In the present invention, a portion of the upper end of the glass tube protrudes from the surface of the heat conducting plate, so that the sunlight irradiation area of ​​the heat collecting plate assembly is increased, thereby improving the absorption of solar heat. At the same time, the upper end of the glass tube directly exchanges heat with the solar heat through a heat medium, thereby improving the heat conversion efficiency. At the same time, the heat conducting fins in the heat conducting plate can improve the downward transfer of heat, thereby heating the lower end of the glass tube at the same time, further improving the heat conversion efficiency, thereby improving the heat collection efficiency.

[0024] During use, dust in the air will gradually fall onto the tempered glass, thereby blocking sunlight, reducing the intensity of sunlight on the solar collector assembly, and affecting the heat collection effect of the solar collector assembly. At this time, the dust on the surface of the tempered glass can be cleaned by the self-cleaning mechanism, and the light transmittance of the tempered glass can be increased again, thereby enhancing the heat collection effect of the solar collector assembly;

[0025] The amount of dust per unit area on the surface of tempered glass is roughly the same as the amount of dust per unit area on some glass sheets. By comparing the light intensity of several photosensitive sensors, the thickness of the dust can be roughly detected, so as to determine whether dust treatment is required, avoiding frequent cleaning and energy waste, and also achieving the purpose of automatic cleaning.

[0040] See also Figure 1-9A solar thermal collection system with a solar thermal collection mechanism having self-cleaning and monitoring functions, comprising a solar thermal collection mechanism, a self-cleaning mechanism and a monitoring mechanism. The upper end surface of the solar thermal collection mechanism is provided with a self-cleaning mechanism, the solar thermal collection mechanism is used to collect solar heat, the self-cleaning mechanism is used to wash away dust on the surface of the solar thermal collection mechanism, the self-cleaning mechanism is electrically connected to the monitoring mechanism through a data line, and the monitoring mechanism is used to monitor the amount of dust on the solar thermal collection mechanism in real time.

[0041] The solar thermal collection mechanism includes an installation frame 1, a heat collecting plate assembly, and a tempered glass 2. An upper side frame 3 is fixedly connected to the left side of the installation frame 1, and a lower side frame 4 is fixedly connected to the right side of the installation frame 1. When in use, the installation frame 1 is tilted according to the angle of sunlight exposure, and the upper side frame 3 is located at the upper end of the inclined surface, and the lower side frame 4 is located at the lower end of the inclined surface. The bottom of the installation frame 1 is fixedly connected to the heat collecting plate assembly, and the tempered glass 2 is fixedly connected to the frame opening at the upper end of the installation frame 1. The tempered glass 2 is used to protect the interior of the installation frame 1 and can allow sunlight to irradiate on the heat collecting plate assembly, so that the heat collecting plate assembly can absorb heat from the sunlight to achieve the purpose of heat collection.

[0042] The self-cleaning mechanism includes a translation block 5, a wiper, a brushing assembly, and a flushing assembly. The translation block 5 is slidably connected to the upper end of the tempered glass 2. A wiper is provided on one side of the translation block 5, and the wiper is used to scrape off water stains. A brushing assembly is provided at the lower end of the translation block 5, and the brushing device is used to brush the surface of the tempered glass 2. A flushing assembly is provided on the other side of the translation block 5, and the flushing assembly is used to spray water. Both ends of the translation block 5 are respectively connected to the upper frame 3 and the lower frame 4 through a transmission device.

[0043] like Figure 1 , Figure 5 As shown, the monitoring mechanism includes a photosensitive sensor 6, a timer 7 and a controller 8. A plurality of fixing grooves are respectively provided on the upper end faces of the upper frame 3. A mounting hole 9 is provided at the center of the bottom of the fixing groove. The photosensitive sensor 6 is fixedly installed in the mounting hole 9. A glass sheet 10 is embedded in the fixing groove. The photosensitive sensor 6 is installed in the mounting hole 9. Light can only pass through the glass sheet 10 and then shine on the photosensitive sensor 6 through the mounting hole 9. Therefore, when dust accumulates on the glass sheet 10, the light in the mounting hole becomes darker, and the dust on the glass sheet 10 is detected, so that the self-cleaning mechanism is started through the controller 8 to clean the dust.

[0044] The upper end surface of the glass sheet 10 is flush with the end surface of the upper frame 3, the photosensor 6 is connected to the controller 8 via a data line, the controller 8 is fixedly connected to the outer side wall of the mounting frame 1, the timer 7 is fixedly connected to one side of the controller 8, and the timer 7 is connected to the controller 8 via a data line. The timer 7 can perform dust cleaning on the tempered glass 2 at a regular time through the controller 8.

[0045] A fourth drive motor 46 is engaged and connected to the upper frame 3 on one side of the fixed groove, and a cleaning rod 47 is fixedly connected to the rotating shaft of the fourth drive motor 46. A cleaning brush 48 is fixedly connected to the lower end of the cleaning rod 47, and the cleaning brush 48 is in contact with the upper end of the glass sheet 10 for cleaning the dust on the glass sheet 10. When in use, a part of the fourth drive motors 46 automatically rotates every period of time, thereby driving the cleaning brush 48 to clean the dust on the glass sheet 10, and the remaining fourth drive motors 46 remain in an inoperative state, so that dust falls naturally on the glass sheet 10. The unit dust falling amount on the tempered glass 2 is roughly the same as that on the glass sheet 10. The photosensitive sensor 6 facing the dusty glass sheet 10 is compared with the photosensitive sensor 6 facing the non-dusted glass sheet 10, so that the unit dust falling amount can be roughly detected. When the value reaches the threshold, the self-cleaning mechanism is started by the controller 8 to clean the dust on the tempered glass 2, thereby improving the light transmittance of the tempered glass 2 and improving the heat collection efficiency of the heat collecting plate assembly.

[0046] like Figure 2 As shown, in some embodiments of the present invention, connecting grooves are respectively opened in the installation frame 1 on both sides and the bottom of the solar collector assembly, and the insulation layer 11 is fixedly connected in the connecting grooves. The gap between the tempered glass 2 and the solar collector assembly is vacuum or filled with inert gas to prevent heat loss.

[0047] like Figure 2 , Figure 4 , Fig. 9 As shown, the heat collecting plate assembly includes a heat conducting plate 12, heat conducting fins 13, glass tubes 14, and a heat absorbing coating 15. The heat conducting plate 12 is fixedly connected to the bottom of the insulation layer 11. A plurality of relatively parallel glass tubes 14 are embedded and connected to the upper end of the heat conducting plate 12. The heat absorbing coating 15 is evenly coated on the upper ends of the glass tubes 14 and on the heat conducting plates 12 between the glass tubes 14. The heat absorbing coating 15 is used to enhance the absorption of heat from sunlight. Heat conducting fins 13 are respectively fixedly connected in the heat conducting plates 12 between the glass tubes 14. The heat conducting fins 13 are used to transfer the heat from the upper end of the heat conducting plate 12 downward. Heat conducting strips 16 are respectively fixedly connected on both sides of the lower end of the heat conducting fins 13, which are used to evenly disperse the heat transferred downward to the bottom of the glass tubes 14, thereby improving the heat exchange efficiency of the heat medium in the glass tubes 14.

[0048] A cold water collecting chamber 17 is opened in the lower frame 4 and connected to the cold water collecting chamber 17, which is connected to the right end of the glass tube 14. A hot water collecting chamber 18 is opened in the upper frame 3, and the left end of the glass tube 14 is connected to the hot water collecting chamber 18. Both ends of the upper frame 3 and the lower frame 4 are fixedly connected to water receiving pipes 19.

[0049] Specifically, during use, sunlight passes through the tempered glass 2 and directly irradiates the heat-absorbing coating 15. The temperature of the heat-absorbing coating 15 rises after absorbing heat. The upper end of the glass tube 14 is in direct contact with the heat-absorbing coating 15. The heat medium in the glass tube 14 directly transfers the heat of the heat-absorbing coating 15 through heat exchange. The heat-absorbing coating 15 on the heat-conducting plate 12 transfers the heat to the heat-conducting plate 12. The heat-conducting fins 13 inside the heat-conducting plate 12 can improve the heat conduction efficiency of the heat-conducting plate 12, so that the heat is quickly transferred from the surface to the bottom of the heat-conducting plate 12. After the heat-conducting plate 12 is heated, the glass tube 14 wrapped inside the heat-conducting plate 12 is heated, so as to further improve the heat conversion efficiency of the heat medium, thereby improving the heat collection efficiency.

[0050] like Figure 6 , Figure 7 , Figure 8 As shown, the wiper includes a first drive motor 20, a linkage rod 21, a mounting strip 22, a guide strip 23, and a wiper strip 24. A plurality of evenly spaced limit grooves 25 are respectively provided on the left side surface of the translation block 5. The cross section of the limit groove 25 is a triangular structure. One end of the linkage rod 21 is rotatably connected to the bottom of the limit groove 25, that is, one end of the linkage rod 21 is located at a corner of the triangular structure, and the linkage rod 21 moves between the two adjacent sides of the corner. The other end of the limit groove 25 is fixedly connected to the upper end of the mounting strip 22. A guide strip is provided at the lower end of the mounting strip 22. The guide strip 23 is slidably connected in the guide strip. The lower end of the guide strip 23 is fixedly connected to the wiper strip 24. The wiper strip 24 is used to scrape off water stains.

[0051] The brushing device includes a sliding plate 26, a brush 27, a guide rod 28, a connecting rod 29, a second drive motor 30, and a rotating disk 31. A movable groove 32 is provided at the lower end of the translation block 5. The sliding plate 26 is slidably connected in the movable groove 32. The lower end surface of the sliding plate 26 is fixedly connected with a brush 27 for cleaning dust on the surface of the tempered glass 2. A plurality of transfer guide grooves 33 are provided at the upper end of the movable groove 32. The guide rod 28 is slidably connected in the transfer guide groove 33. The lower end of the guide rod 28 is fixedly connected to the upper end of the sliding plate 26. The middle part of the upper end of the sliding plate 26 is rotatably connected with a connecting rod 29. The other end of the connecting rod 29 is rotatably connected to the lower edge of the rotating disk 31. The middle part of the upper end of the rotating disk 31 is fixedly connected to the rotating shaft of the second drive motor 30. The second drive motor 30 is embedded and connected to the middle part of the right side of the translation block 5.

[0052] The flushing assembly includes a flushing pipe 34, a nozzle 35, and a submersible pump 36. The second driving motor 30 on the side of the translation block 5 is fixedly connected to the flushing pipe 34 on both sides through a bracket. A plurality of nozzles 35 are fixedly connected to the outer wall of the flushing pipe 34. The translation block 5 is respectively provided with symmetrical water storage chambers 37, and a submersible pump 36 is fixedly installed in the water storage chamber 37. The submersible pump 36 is used to transport clean water, and one end of the submersible pump 36 is fixedly connected to one end of the corresponding flushing pipe 34 through a water pipe.

[0053] The transmission device includes a third driving motor 39, a driving block 40, a transmission screw 41, a hook frame 42, and a limit rod 43. Slide groove openings 44 are respectively opened on the groove walls on both sides of the drainage groove 38. One end of the transmission screw 41 is rotatably connected to the inner side of the slide groove opening 44, and the other end of the screw is rotated on the fixed plate 45. The fixed plate 45 is fixedly connected to the upper frame 3. The hook frame 42 is fixedly connected to the lower end edge of the outer side of the driving block 40. The cross-section of the hook frame 42 is a J-shaped structure. The limit rod 43 is fixedly connected to the two side edges of the upper end of the installation frame 1, and the lower end of the limit rod 43 is respectively opened with a driving groove. The lower end of the hook frame 42 is slidably connected in the driving groove. The third driving motor 39 is embedded and connected to one side of the fixed plate 45, and the rotating shaft of the third driving motor 39 is fixedly connected to the transmission screw 41.

[0054] During the cleaning process, first, the fourth driving motor 46 drives the two sets of transmission screws 41 to rotate, and the transmission screws 41 drive the driving block 40 to slide along the upper edge of the mounting frame 1, and the driving block 40 drives the self-cleaning mechanism to slide translationally on the surface of the tempered glass 2. The hook frames 42 on both sides of the driving block 40 are hooked and connected with the limit rods 43 on the edges of both sides of the mounting frame 1, and the hook frames 42 can be slidably connected to the driving groove at the lower end of the limit rods 43, which can make the sliding of the driving block 40 more stable.

[0055] Driven by the driving block 40, the translation slider first slides out of the drainage groove 38 to the mounting frame 1, and moves from the lower frame 4 to the upper frame 3. During this process, the submersible pump 36 transports the clean water in the water storage chamber 37 to the flushing pipe 34 through the water pipe, and then the surface of the tempered glass 2 is sprayed with water through the nozzle 35 on the flushing pipe 34; at the same time, the second driving motor 30 drives the rotating disk 31 to rotate, and the connecting rod 29 at the lower end edge of the rotating disk 31 drives the sliding plate 26 to slide back and forth in the movable groove 32, so that the brush 27 at the lower end of the sliding plate 26 brushes the surface of the tempered glass 2.

[0056] The above process is driven by the driving block 40 to reciprocate between the upper frame 3 and the lower frame 4 2-3 times to thoroughly clean the surface of the tempered glass 2. The last time the driving block 40 drives the translation block 5 to move to the upper frame 3 and starts to move toward the lower frame 4, the first driving motor 20 drives the linkage rod 21 to rotate, and the other end of the linkage rod 21 drives the mounting strip 22 to rotate at a certain angle, so that the wiper strip 24 at the lower end of the mounting strip 22 is in conflict with the surface of the tempered glass 2. After that, when the translation block 5 moves toward the lower frame 4, the wiper strip 24 scrapes the water stains on the surface of the tempered glass 2 to the lower frame 4 until the translation block 5 is re-stored into the drainage groove 38.

[0057] During the whole process, the sewage flows along the tempered glass 2 toward the lower frame 4 and finally flows into the drainage trough 38. A drainage pipe is provided at the bottom of the drainage trough 38, and finally the sewage is discharged through the drainage pipe.

[0058] like Fig. 9 As shown, a drainage trough 38 is provided at the upper end of the lower frame 4 for collecting sewage flowing down from the tempered glass 2, and the self-cleaning mechanism is received and connected in the drainage trough 38 to prevent the cleaning device from blocking sunlight.

[0059] In some embodiments of the present invention, a threaded hole is provided on the outer side of the mounting strip 22. After the screw is threadedly connected to the threaded hole, the end of the screw is in contact with the opposite side of the sliding guide strip 23. The wiper strip 24 is made of rubber. When the wiper strip 24 is aged and cannot scrape off water stains, the screw is unscrewed, the sliding guide strip 23 is pulled out of the sliding guide groove, and a new sliding guide strip 23 is inserted along the sliding guide groove and fixed again with the screw.

[0060] In some embodiments of the present invention, the self-cleaning mechanism works at night to avoid affecting the collection of solar heat by the solar collector assembly during the day.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
