Description

Technical Field

[0001] This invention relates to the technical field of curtain wall cleaning, and more specifically to an intelligent cleaning system for building photovoltaic curtain walls. Background Technology

[0002] In today's society, with the continuous growth of energy demand and the increasing awareness of environmental protection, photovoltaic technology, as a renewable energy technology, has been widely used. Building photovoltaic (PV) curtain walls, as an innovative form that combines photovoltaic power generation technology with architectural aesthetics, not only provide electricity to buildings but also beautify their appearance. However, during long-term operation, dust, dirt, and other pollutants accumulate on the surface of PV curtain walls. This not only affects the power generation efficiency of the PV curtain wall and reduces its energy output but may also lead to localized overheating of the PV modules, thereby shortening their lifespan.

[0003] In addition, traditional manual cleaning methods have many drawbacks, such as low cleaning efficiency, difficulty in guaranteeing cleaning quality, and safety hazards associated with working at heights. Therefore, unmanned cleaning devices for building photovoltaic (PV) curtain walls have emerged. Workers can remotely control the operation to clean the PV curtain walls. However, the following problems still exist: When cleaning the PV curtain walls, some of the water sprayed by the unmanned cleaning device flows quickly down the PV curtain wall after use, softening some stubborn dirt on the surface. However, some wastewater falls directly down and is difficult to reuse, meaning the unmanned cleaning device still needs to remove a significant amount of unsoftened, stubborn dirt, resulting in low cleaning efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent cleaning system for building photovoltaic curtain walls to overcome the above-mentioned defects in the prior art.

[0005] A smart cleaning system for building photovoltaic (PV) curtain walls includes a cleaning robot body. The cleaning robot body is equipped with a cleaning unit for cleaning the PV curtain wall and a walking unit for driving the cleaning robot body to perform adsorption and movement. The top of the cleaning robot body is equipped with a monitoring camera for observing whether the PV curtain wall is clean and an environmental monitoring device for monitoring the ambient wind force, temperature, and humidity. The monitoring camera and environmental monitoring device are connected to a wireless communication module in the cleaning robot body, and the wireless communication module is connected to a remote control terminal. The bottom of the cleaning robot body is also equipped with a pre-cleaning mechanism for pre-cleaning the PV curtain wall.

[0006] Preferably, the pre-cleaning mechanism includes a sludge guide box, an impeller, and a scraping assembly. The sludge guide box is located at the bottom of the cleaning robot body. The impeller is rotatably connected to the drain outlet at the lower end of the sludge guide box via a rotating shaft. The scraping assembly is located on the sludge guide box. Driven by the sewage, the impeller drives the scraper on the scraping assembly to clean the photovoltaic curtain wall.

[0007] Preferably, the scraping assembly further includes a drive plate, a support plate, and a sliding plate. One end of the drive plate is connected to a rotating shaft. The support plate is located on the side of the cleaning robot body. The sliding plate is rotatably connected to the side of the support plate via a pin. One end of the scraper is hinged to the other end of the drive plate via a pin. The scraper is slidably connected to the sliding plate.

[0008] Preferably, the overall structure of the wastewater guide box is a triangular structure with openings at the top and inside.

[0009] Preferably, a rubber abutment is provided around the upper edge of the sewage guide box to abut against the surface of the photovoltaic curtain wall.

[0010] Preferably, the sewage guide box is provided with a guide bucket at the lower end of the sewage outlet.

[0011] Preferably, the guide hopper includes a side plate and an inclined plate. The side plates are provided in two and symmetrically arranged on both sides of the sludge guide box, and the inclined plate is arranged between the two side plates.

[0012] Preferably, the scraper is provided with a triangular rubber scraper strip.

[0013] Preferably, the support plate has a Z-shaped structure.

[0014] The beneficial effects achieved by this invention are as follows:

[0015] 1. This system achieves automated cleaning through the cleaning robot itself, reducing manual intervention and significantly improving cleaning efficiency. Operators can control the cleaning robot via a remote control terminal, eliminating the need for direct contact with the photovoltaic curtain wall and reducing the risks of working at heights. Simultaneously, monitoring cameras can observe the cleaning status of the photovoltaic curtain wall in real time, allowing operators to adjust cleaning strategies promptly based on the monitoring footage to ensure cleaning quality. Furthermore, environmental monitoring equipment can monitor environmental conditions such as wind speed, temperature, and humidity in real time and transmit the data to the remote control terminal. Operators can adjust cleaning plans based on this data, avoiding cleaning work in inclement weather conditions and improving the system's environmental adaptability.

[0016] 2. The wastewater guide box of this application can effectively collect the water sprayed by the cleaning unit and guide the wastewater to the drain outlet. The rubber edge design ensures that the wastewater guide box fits tightly against the photovoltaic curtain wall surface. The side plates and inclined plate structure of the guide bucket can guide the discharged wastewater to the photovoltaic curtain wall surface below the cleaning robot body, realizing the secondary utilization of water resources. Before the cleaning unit sprays water for cleaning, the pre-cleaning mechanism can soften the dirt on the photovoltaic curtain wall surface. During the discharge of wastewater from the wastewater guide box, the impeller is driven to rotate. The impeller drives the scraper and its rubber scraper strip on the scraping component to swing through the rotating shaft, pre-cleaning the dirt on the photovoltaic curtain wall surface. This pre-cleaning method can effectively soften the dirt, making it easier to be rinsed away by the water sprayed by the cleaning unit, thereby improving the cleaning effect. At the same time, the triangular structure design of the rubber scraper strip can better fit the photovoltaic curtain wall surface, ensuring the scraping effect. Attached Figure Description

[0027] like Figure 1-6 As shown, the present invention provides an intelligent cleaning system for building photovoltaic curtain walls, including a cleaning robot body 1. The cleaning robot body 1 is equipped with a cleaning unit 2 for cleaning the photovoltaic curtain wall and a walking unit 3 for driving the cleaning robot body 1 to perform adsorption and movement. The top of the cleaning robot body 1 is equipped with a monitoring camera 4 for observing whether the photovoltaic curtain wall is clean and an environmental monitoring device 5 for monitoring the ambient wind force, temperature and humidity. The monitoring camera 4 and the environmental monitoring device 5 are connected to a wireless communication module in the cleaning robot body 1. The wireless communication module is connected to a remote control terminal, so that workers can remotely operate the cleaning robot body 1.

[0028] It should be noted that the bottom of the cleaning robot body 1 is also provided with a pre-cleaning mechanism 6 for pre-cleaning the photovoltaic curtain wall. The pre-cleaning mechanism 6 includes a dirt guide box 61, an impeller 62 and a scraping component 65. The dirt guide box 61 is located at the bottom of the cleaning robot body 1. The dirt guide box 61 is a triangular structure with an opening at the top and inside. A rubber abutment 611 is provided around the edge of the top of the dirt guide box 61 to abut against the surface of the photovoltaic curtain wall, which can ensure that the dirt guide box 61 is in close contact with the surface of the photovoltaic curtain wall.

[0029] In addition, the impeller 62 is rotatably connected to the drain port 64 at the lower end of the sludge guide box 61 via the rotating shaft 63. The sludge guide box 61 is provided with a guide bucket 66 at the lower end of the drain port 64. The guide bucket 66 includes a side plate 661 and an inclined plate 662. There are two side plates 661, which are symmetrically arranged on both sides of the sludge guide box 61. The inclined plate 662 is located between the two side plates 661. The guide bucket 66 can guide the discharged sewage to the photovoltaic curtain wall surface below the cleaning robot body 1.

[0030] In addition, the scraping assembly 65 is mounted on the sewage guide box 61. The impeller 62 drives the scraper 651 on the scraping assembly 65 to clean the photovoltaic curtain wall under the drive of sewage. The scraping assembly 65 also includes a drive plate 653, a support plate 654 and a sliding plate 655. One end of the drive plate 653 is connected to the rotating shaft 63. The support plate 654 is located on the side of the cleaning robot body 1. The sliding plate 655 is rotatably connected to the side of the support plate 654 by a pin.

[0031] In addition, the scraper 651 is slidably connected to the slide plate 655, and the scraper 651 is provided with a triangular rubber scraper 652. The rubber scraper 652 can better fit the surface of the photovoltaic curtain wall and ensure the scraping effect.

[0032] Detailed implementation methods and principles:

[0033] When in use, the cleaning robot body 1 is placed on top of the surface of the building photovoltaic curtain wall. The vacuum suction cup on the walking unit 3 is used to adsorb the surface of the photovoltaic curtain wall. The environmental monitoring device 5 monitors the environmental wind force, temperature and humidity data at all times and transmits them to the remote control terminal. The cleaning unit 2 sprays water to clean the surface of the photovoltaic curtain wall. The monitoring camera 4 is used to observe whether the photovoltaic curtain wall is clean. Workers can remotely control the cleaning robot body 1 to walk on the surface of the photovoltaic curtain wall.

[0034] Water sprayed from cleaning unit 2 enters the sludge guide box 61 through rubber abutment 611 and is discharged through the drain port 64 of sludge guide box 61. Under the action of inclined plate 662 on the guide bucket 66, water is sprayed onto the surface of photovoltaic curtain wall below the cleaning robot body 1. At the same time, as the sewage is discharged from sludge guide box 61, it drives the impeller 62 on the rotating shaft 63 to rotate. The drive plate 653 on the rotating shaft 63 drives the scraper 651 and its rubber scraper 652 to swing and soften and pre-clean the dirt on the surface of photovoltaic curtain wall.

[0035] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention.
