Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of photoelectric sunshine recorders, and particularly relates to an automatically cleanable photoelectric sunshine recorder. Background Art

[0002] After the existing photoelectric digital sunshine recorder works for a long time, the mirror surface of the sunshine recorder is easily covered with dust and impurities due to external factors, resulting in a significant reduction in the working efficiency of the sunshine recorder. Especially in corresponding rainy and snowy weather, the covered snow will directly cause the sunshine recorder to fail to work. The existing cleaning method generally involves manually wiping and cleaning with a cleaning cloth multiple times, with low working efficiency and high labor intensity, and cannot meet the actual use requirements.

[0003] Chinese Patent Publication No. CN218411437U discloses a calibration structure of a photoelectric digital sunshine recorder, including that two connecting rings are welded on the surface of the support column of the photoelectric digital sunshine recorder, a control box is fixedly installed on the left side of the two connecting rings, a base one is welded on the top of the connecting ring, a plurality of threaded columns are welded on the top of the base one, a calibration nut is threadedly connected to the middle of the surface of the threaded column, a base two is arranged on the top of the base one, the base two slides on the surface of the three threaded columns, a mounting plate is welded on the top of the base two, a photoelectric digital sunshine recorder body is rotatably connected to the rear side of the mounting plate, light inlet holes are arranged on the front side and the rear side of the photoelectric digital sunshine recorder body, and a bubble level is fixedly installed on the front side of the top of the base two.

[0004] However, the sunshine recorder in the above device needs to be manually cleaned after long-term use, and the cleaning efficiency is low. Moreover, when the temperature is too low in winter, the frozen snow or rainwater on the sunshine recorder cannot be eliminated in time. Content of the Utility Model

[0005] The utility model aims to overcome the disadvantages that after the sunshine recorder in the above-mentioned prior art is used for a long time, it needs to be manually cleaned with low cleaning efficiency, and when the temperature is too low in winter, the frozen snow or rainwater on the sunshine recorder cannot be eliminated in time.

[0006] A photoelectric sunshine recorder capable of automatic cleaning is proposed, which includes a photoelectric sunshine recorder, and also includes a mounting plate for mounting the photoelectric sunshine recorder, a cleaning device for cleaning the surface of the photoelectric sunshine recorder, a water storage component for cleaning the photoelectric sunshine recorder together with the cleaning device, a hot air component for heating the surface of the photoelectric sunshine recorder, and a transmission device for driving the cleaning device to move horizontally. The photoelectric sunshine recorder is arranged at the center position of the upper surface of the mounting plate. The cleaning device is sleeved on the photoelectric sunshine recorder, and the cleaning device is connected to the water storage component and the hot air component. The water storage component is arranged on the mounting plate and is located on one side of the photoelectric sunshine recorder. The hot air component is arranged at the center position of the top end of the water storage component. The transmission device passes through the bottom end of the cleaning device and is fixed at the bottom end of the photoelectric sunshine recorder along the length direction of the photoelectric sunshine recorder.

[0007] In the technical solution of the present utility model, when it is necessary to clean the sunshine recorder, the transmission device can drive the cleaning device to move horizontally. While the cleaning device is moving horizontally, the motor inside the gearbox can drive the driven gear to rotate through the driving gear. A cleaning brush is arranged on the inner wall of the driven gear. Therefore, the surface of the sunshine recorder can be cleaned while the driven gear is rotating. Before the cleaning brush cleans the sunshine recorder, clean water can be sprayed on the surface of the sunshine recorder through the water injection ring to ensure the cleaning quality of the cleaning brush, so as to solve the disadvantages mentioned in the technical background that after long-term use, manual cleaning is required and the cleaning efficiency is low.

[0008] Before cleaning the surface of the sunshine recorder in winter, the cleaning ring will first push down the snow or accumulated water on the surface of the sunshine recorder. If the rain and snow falling on the sunshine recorder have been frozen into ice due to too low temperature, before the cleaning brush cleans the sunshine recorder, hot air can be sprayed on the surface of the sunshine recorder through the hot air ring to heat the temperature of the surface of the sunshine recorder, thereby melting the rain and snow frozen on the surface of the sunshine recorder. At the same time, after cleaning, the water sprayed on the surface of the sunshine recorder by the cleaning device during cleaning can also be dried by the hot air ring, avoiding the water sprayed on the surface of the sunshine recorder being frozen into ice due to too low temperature, so as to solve the disadvantages mentioned in the technical background that when the temperature is too low in winter, the frozen snow or rain on the sunshine recorder cannot be eliminated in time.

[0009] For the optimization of the technical solution of the present utility model, the water storage assembly includes a water storage tank, a water pump and a diversion pipe. The water storage tank is fixedly connected to the mounting plate. The water pump is arranged on the top plate of the water storage tank. The water inlet of the water pump is connected to the inside of the water storage tank by a pipe. One end of the diversion pipe is connected to the water outlet of the water pump, and the other end of the diversion pipe is connected to the water injection ring of the cleaning assembly. In summer, clean water can be added to the inside of the water storage tank regularly. When cleaning the sunshine recorder, the clean water can be pumped out by the water pump and transported to the inside of the water injection ring through the water diversion pipe. Then, the clean water is sprayed on the surface of the sunshine recorder by the water injection ring to soften the impurities on the surface of the sunshine recorder, so as to ensure that when the cleaning device cleans the sunshine recorder, the cleaning device can completely wash off the impurities on the surface of the sunshine recorder.

[0010] For the optimization of the technical solution of the present utility model, the hot air assembly includes a hot air blower and a duct. The hot air blower is fixedly connected to the top plate of the water storage tank. One end of the duct is connected to the air outlet of the hot air blower, and the other end of the duct is connected to the hot air ring of the cleaning assembly. After the cleaning device finishes cleaning the sunshine recorder, the hot air generated by the hot air blower can be transported to the inside of the hot air ring through the duct, and the hot air is sprayed on the surface of the sunshine recorder through the hot air ring to dry the water on the surface of the sunshine recorder, avoiding the formation of drip marks when the clean water evaporates on the surface of the sunshine recorder. And in winter, before the cleaning device cleans the sunshine recorder, the snow and rain frozen on the surface of the sunshine recorder can be melted first through the hot air ring, so as to improve the cleaning efficiency of the cleaning device. At the same time, the water remaining on the surface of the sunshine recorder can be dried after cleaning, avoiding it from freezing on the surface of the sunshine recorder again.

[0011] For the optimization of the technical solution of the present utility model, a snow shield is provided on the hot air blower. The snow shield can block the falling snow or rain outside the hot air blower, avoiding the hot air blower from being eroded by rain or falling snow, and the snow shield does not affect the normal operation of the hot air blower.

[0012] For the optimization of the technical solution of the present utility model, the cleaning device includes a cleaning ring, a gear box, a motor, a main gear, a sub-gear, a cleaning brush, a water injection ring and a hot air ring. The bottom end of the cleaning ring is connected to the transmission device, and the gear box is connected to one side of the cleaning ring. The motor is horizontally connected inside the gear box. The main gear is fixed on the output end of the motor, and the main gear passes through the cleaning ring and meshes with the sub-gear inside the cleaning ring. The sub-gear is arranged at one end inside the cleaning ring, and the cleaning brush is connected to the inner wall of the sub-gear. The water injection ring is arranged at the other end inside the cleaning ring, and the hot air ring is also arranged inside the cleaning ring and is located on one side of the water injection ring. While the cleaning ring is driven by the transmission device to move horizontally, the motor drives the sub-gear and the cleaning brush on the inner wall of the sub-gear to rotate by rotating the main gear. Since the cleaning brush is sleeved on the sunshine recorder, when the cleaning brush rotates, it can better clean the outer wall of the sunshine recorder.

[0013] For the optimization of the technical solution of the present utility model, a plurality of through holes are provided on the inner wall of the cleaning ring. After clear water and hot air enter the interior of the water injection ring and the hot air ring respectively, they can directly contact the surface of the sunshine recorder, so as to improve the cleaning and drying efficiency of the cleaning device.

[0014] For the optimization of the technical solution of the present utility model, the transmission device is an electric lead screw. The electric lead screw has excellent repeatability and can repeatedly and precisely execute the same linear motion task without cumulative error. Moreover, the electric lead screw can provide very high linear position control accuracy and will not leave dead corners when cleaning the sunshine recorder.

[0015] The beneficial effects of the present utility model compared with the prior art are as follows:

[0016] 1. When it is necessary to clean the sunshine recorder, the cleaning device can be driven by the transmission device to move horizontally. When the cleaning device moves horizontally, the rotation of the secondary gear can drive the cleaning brush to rotate together.

Detailed implementation mode

[0024] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-5 to describe in detail the technical solutions in the embodiments of the present utility model.

[0025] As Figure 1 shown, a photoelectric sunshine recorder capable of automatic cleaning includes a photoelectric sunshine recorder 1. The photoelectric sunshine recorder 1 is fixedly connected to the center position at the top end of the mounting plate 2. The cleaning device 3 is sleeved on the photoelectric sunshine recorder 1. The transmission device 6 passes through the bottom end of the cleaning device 3 and is arranged at the bottom end of the photoelectric sunshine recorder 1 along the length direction of the photoelectric sunshine recorder 1. When the transmission device 6 is started, the cleaning device 3 can move horizontally by using the transmission device 6. While the cleaning device 3 is moving horizontally, it starts to clean the outer surface of the photoelectric sunshine recorder 1.

[0026] As Figure 1 shown, since the transmission device 6 is fixedly connected to the photoelectric sunshine recorder 1, when the photoelectric sunshine recorder 1 adjusts the angle, the transmission device 6 and the cleaning device 3 will move together with the photoelectric sunshine recorder 1 to ensure that the photoelectric sunshine recorder 1 can be correctly cleaned. On one side of the photoelectric sunshine recorder 1 on the mounting plate 2, a water storage assembly 4 is further provided. The water storage assembly 4 is fixedly connected to the top end of the mounting plate 2, and the water storage assembly 4 is connected to the cleaning device 3 by a water pipe. A snow shield 7 is fixedly connected to the top plate of the water storage assembly 4, and a hot air assembly 5 is arranged inside the snow shield 7.

[0027] As Figure 2 shown, the water storage assembly 4 includes a water storage tank 41, a water pump 42 and a diversion pipe 43. The water storage tank 41 is located on one side of the photoelectric sunshine recorder 1 and is fixedly connected to the top end of the mounting plate 2. The water pump 42 is fixedly connected to the top plate of the water storage tank 41. The hot air blower 51 of the hot air assembly 5 is located on one side of the water pump 42. The water inlet of the water pump 42 is connected to the inside of the water storage tank 41 through a pipe passing through the top plate of the water storage tank 41. The clear water regularly added to the inside of the water storage tank 41 through the water inlet of the water storage tank 41 is pumped out by the water pump 42 through the pipe and transported through the diversion pipe 43.

[0028] As Figure 2As shown in the figure, one end of the diversion pipe 43 is connected to the water outlet of the water pump 42, and the other end of the diversion pipe 43 is connected to the water injection ring 37 inside the cleaning device 3. The clear water pumped out from the inside of the water storage tank 41 by the water pump 42 can be transported through the diversion pipe 43 to the inner wall of the water injection ring 37 and sprayed on the surface of the photoelectric sunshine recorder 1 through the water injection ring 37 to soften the impurities on the photoelectric sunshine recorder 1, so as to ensure the cleaning efficiency and quality of the cleaning device 3.

[0029] As Figure 2 shown in the figure, the hot air component 5 includes a hot air blower 51 and a duct 52. The hot air blower 51 is located on one side of the water pump 42 and is fixedly connected to the top plate of the water storage tank 41. A snow shield 7 is covered on the hot air blower 51, and the snow shield 7 is also fixedly connected to the top plate of the water storage tank 41. Therefore, when the hot air blower 51 is working, the snow shield 7 can block the falling snow or rain outside the hot air blower 51 to avoid the hot air blower 51 being eroded by rain or snow, and at the same time the snow shield 7 will not affect the normal operation of the hot air blower 51.

[0030] As Figure 2 shown in the figure, one end of the duct 52 is connected to the air outlet of the hot air blower 51, and the other end of the duct 52 is connected to the hot air ring 38 inside the cleaning component. Therefore, after the cleaning device 3 finishes cleaning the surface of the photoelectric sunshine recorder 1, the hot air blown out through the hot air ring 38 can quickly dry the surface of the photoelectric sunshine recorder 1 to avoid forming drip marks when the clear water on the surface of the photoelectric sunshine recorder 1 dries.

[0031] As Figure 2 shown in the figure, the used transmission device 6 is an electric lead screw. The electric lead screw has excellent repeatability, can repeatedly and precisely execute the same linear motion task without cumulative error, and the electric lead screw can provide very high linear position control accuracy. Therefore, when the electric lead screw controls the cleaning device 3 to clean the sunshine recorder, the cleaning device 3 will not leave dead corners. One end of the electric lead screw passes through the cleaning device 3 and is connected to the bottom end of the photoelectric sunshine recorder 1. Therefore, when the transmission device 6 is started, the electric lead screw rotates forward or backward to drive the cleaning device 3 to move horizontally.

[0032] As Figure 3 shown in the figure, the cleaning device 3 includes a cleaning ring 31, a gear box 32, a motor 33, a main gear 34, a sub-gear 35, a cleaning brush 36, a water injection ring 37 and a hot air ring 38. The gear box 32 is fixedly connected to one side of the cleaning ring 31. Therefore, when the cleaning device 3 is driven by the transmission device 6 to rotate, the gear box 32 will move together with the cleaning ring 31. The motor 33 is arranged inside the gear box 32, and the motor 33 is horizontally fixedly connected inside the gear box 32. The main gear 34 is fixedly connected to the output end of the motor 33. Therefore, when the motor 33 is started, the main gear 34 will rotate together with the output end of the motor 33.

[0033] As shown Figure 3 in Figure Figure 3 , the main gear 34 passes through the cleaning ring 31 and meshes with the secondary gear 35 inside the cleaning ring 31. The secondary gear 35 is located at one end of the cleaning ring 31 and is rotatably connected inside the cleaning ring 31. Therefore, when the main gear 34 is driven by the motor 33 to rotate, the secondary gear 35 will be driven by the main gear 34 to rotate together. At the same time, since the cleaning ring 31 is sleeved on the photoelectric sunshine recorder 1, the secondary gear 35 and the cleaning ring 31 are sleeved on the photoelectric sunshine recorder 1 together. So when the main gear 34 is driven to rotate, the secondary gear 35 will rotate around the photoelectric sunshine recorder 1.

[0034] As shown Figure 4 in Figure Figure 4 , the water injection ring 37 is arranged inside the cleaning ring 31 and is located at the other end of the cleaning ring 31. The hot air ring 38 is also arranged inside the cleaning ring 31 and is located on one side of the water injection ring 37. A plurality of through holes are formed on the inner wall of the cleaning ring 31. After the clear water and hot air are transported to the inside of the water injection ring 37 and the hot air ring 38 through the air duct 52 and the diversion pipe 43, they can directly contact the outer wall of the photoelectric sunshine recorder 1 inside the cleaning ring 31 through the through holes on the inner wall of the cleaning ring 31, so as to improve the cleaning and drying efficiency of the photoelectric sunshine recorder 1.

[0035] As shown Figure 5 in Figure Figure 5 , a cleaning brush 36 is fixedly connected to the inner wall of the secondary gear 35. Therefore, when the secondary gear 35 is driven by the main gear 34 to rotate, the cleaning brush 36 will be driven to rotate together with the secondary gear 35. The cleaning brush 36 is in direct contact with the outer wall of the photoelectric sunshine recorder 1. Therefore, when the cleaning brush 36 is driven to rotate, the cleaning brush 36 can quickly brush off the impurities on the outer wall of the photoelectric sunshine recorder 1, so as to improve the brushing efficiency of the cleaning brush 36.

[0036] The movement process of this embodiment: When cleaning the surface of the photoelectric sunshine recorder 1, the clear water inside the water storage tank 41 can be first pumped out by the water pump 42 through the pipeline, and then the clear water can be transported to the inside of the water injection ring 37 of the cleaning assembly through the diversion pipe 43, and the clear water can be sprayed onto the surface of the photoelectric sunshine recorder 1 through the through holes on the inner wall of the cleaning ring 37 by the water injection ring 37. When the water injection ring 37 sprays water, the motor 33 inside the gearbox 32 is started. After the motor 33 is started, it will drive the main gear 34 at the output end of the motor 33 to rotate.

[0037] Since the secondary gear 35 inside the cleaning ring 31 meshes with the main gear 34, when the main gear 34 is driven by the motor 33 to rotate, the secondary gear 35 will rotate together with the main gear 34. A cleaning brush 36 is connected to the inner wall of the secondary gear 35. So when the secondary gear 35 is driven to rotate by the main gear 34, the cleaning brush 36 will rotate together with the secondary gear 35 to clean the surface of the photoelectric sunshine recorder 1.

[0038] When the cleaning brush 36 rotates, the transmission device 6 drives the cleaning device 3 to move horizontally, so as to ensure that the cleaning brush 36 can clean the entire surface of the photoelectric sunshine recorder 1. After the cleaning brush 36 finishes cleaning, the motor 33 stops rotating, and the water pump 42 also stops delivering clean water into the water injection ring 37. Then the hot air blower 51 is started. The hot air generated when the hot air blower 51 works is also transported through the air duct 52 to the inside of the hot air ring 38. After the hot air enters the inside of the hot air ring 38, it directly contacts the photoelectric sunshine recorder 1 through the through holes on the inner wall of the cleaning ring 31, and dries the surface of the photoelectric sunshine recorder 1.

[0039] Then the transmission device 6 is started again to ensure that the hot air ring 38 can dry the entire surface of the photoelectric sunshine recorder 1. In winter, before the cleaning ring 31 cleans the surface of the photoelectric sunshine recorder 1, the hot air blower 51 can be started first, and the hot air is sprayed on the surface of the photoelectric sunshine recorder 1 through the hot air ring 38. After melting the rain and snow frozen on the surface of the sunshine recorder, the cleaning ring 31 is started to clean the surface of the photoelectric sunshine recorder 1. And after the cleaning brush 36 finishes cleaning the surface of the photoelectric sunshine recorder 1, the hot air blower 51 needs to be started again to dry the surface of the photoelectric sunshine recorder 1, so as to avoid the clean water remaining on the surface of the photoelectric sunshine recorder 1 from being frozen again due to too low temperature.

[0040] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention fall within the protection scope of the present invention.
