Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically an automatic cleaning device for solar panels. Background Technology

[0002] The efficiency of photovoltaic power generation is closely related to the surface cleanliness of solar panels. Since solar panels are exposed to the outdoors for a long time, they are inevitably polluted by the external environment. The dust layer formed on the surface will affect the light transmittance, thereby reducing the conversion efficiency of solar energy.

[0003] The existing cleaning methods mainly include the following: 1. Manual cleaning, which is labor-intensive and limited to small-scale applications, such as rooftop solar panels in rural areas; 2. Equipping each solar panel with a cleaning mechanism, which is highly efficient but significantly increases costs; 3. Using cleaning robots to clean the solar panels. These robots are usually equipped with dust removal devices to remove dust and debris from the solar panels. However, the cleaning robot has a limited working area per cycle and requires multiple repetitions. Furthermore, the robot needs to move across the solar panels, and the rollers or cleaning components may scratch or damage the surface coating, affecting the power generation efficiency of the solar panels.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1 and 2This utility model provides a technical solution: an automatic cleaning device for solar panels, including a base frame 13 and a guide rail 1 fixed to the side wall of the base frame 13. The guide rail 1 is inclined, and a sliding sleeve 3 is slidably mounted on the guide rail 1. The sliding sleeve 3 can move linearly along the guide rail 1. A first spray seat 6 is fixedly connected to one end of the sliding sleeve 3. Multiple nozzles 10 are connected to the bottom of the first spray seat 6. A second spray seat 7 is provided on the rear side of the first spray seat 6. The second spray seat 7 can move linearly laterally. Multiple nozzles 11 are connected to the bottom of the second spray seat 7. The angle between the nozzles 11 and 10 and the surface of the photovoltaic panel is usually 30°-45°, which provides a good cleaning effect. A connecting pipe 15 is fixedly connected to the end of the first spray seat 6 near the second spray seat 7. A through hole 701 is opened on the side of the second spray seat 7 near the first spray seat 6. A rubber ring is fixedly connected to the through hole 701. The rubber ring can ensure improved gas sealing when the through hole 701 corresponds to the connecting pipe 15. An air pump 8 is fixedly installed on the top of the sliding sleeve 3 to provide power for cleaning. This is existing technology. In this application, a rotary vane air pump is used. The rotary vane air pump rotates within the pump body via several vanes on a rotor. As the rotor rotates, the vanes slide within the rotor's slots and contact the inner wall of the pump body, forming sealed chambers. The rotor's rotation draws in and compresses the gas, which is then discharged through the exhaust port. This provides a relatively stable airflow output and higher air pressure, suitable for cleaning photovoltaic panels to help blow away dust, sand, and other contaminants. Oil-free conversion typically employs more precise and durable sealing technologies, such as rubber sealing rings. These rubber sealing rings are usually installed in several key parts of the rotary vane air pump, such as between the pump housing and the rotor, and between the rotor and the end cover, to prevent gas leakage and ensure the airtightness and efficiency of the air pump 8. These seals can operate normally without oil lubrication. An exhaust pipe 9 is fixedly connected to the air delivery end of the air pump 8, and the other end of the exhaust pipe 9 is connected to the first spray seat 6.

[0027] Reference Figure 1 A cylinder 12 is fixedly installed on the side wall of the sliding sleeve 3. The output end of the cylinder 12 is fixedly connected to the side wall of the second spray seat 7. The cylinder 12 can drive the second spray seat 7 to move linearly. The movement of the cylinder 12 is controlled by a programmable logic controller, and a fixed stroke length is set to ensure that the through hole 701 and the connecting pipe 15 can be smoothly connected.

[0028] Reference Figure 6 and Figure 7In specific operations, the device is moved to the working position. When the solar panel area is small, the air pump 8 is directly started. The generated high-pressure gas enters the first spray seat 6 through the exhaust pipe 9. Through the multiple nozzles 10 at the bottom of the first spray seat 6, the high-pressure gas is discharged, blowing away the dust on the surface of the solar panel. At this time, the connecting pipe 15 is in contact with the side wall of the second spray seat 7, which is in a closed state. When the solar panel area is large, the cylinder 12 can be started to drive the first spray seat 6 to move linearly, so that the connecting pipe 15 is aligned with the through hole 701, achieving communication. At this time, the gas enters the second spray seat 7 through the connecting pipe 15 and is discharged through the multiple nozzles 11, also blowing away the dust on the surface of the solar panel. At this time, the nozzles 10 and 11 exhaust simultaneously, achieving the cleaning purpose. The cleaning area is increased; this device can be adjusted according to the area of ​​the solar panel, and can quickly clean the solar panel. Furthermore, this cleaning equipment does not move directly on the surface of the photovoltaic panel, so it will not scratch or damage the surface coating, thus preventing damage to the surface of the photovoltaic panel. High-pressure gas can effectively remove stubborn stains such as dust, bird droppings, and resin from the surface of the photovoltaic panel, especially in cases where they are difficult to remove manually or using traditional cleaning methods. A visual sensor is installed at the bottom of the first spray seat 6 to detect whether the stains have been cleaned, and to perform targeted blowing on the stains if cleaning is not complete. This is an effective way to improve cleaning efficiency and automation. To achieve this function, the visual sensor plays a crucial role, helping the cleaning device to more intelligently determine the condition of the cleaning area.

[0029] Reference Figure 2 A motor 4 is fixedly installed on the side wall of the sliding sleeve 3. A gear 5 is fixedly connected to the output end of the motor 4. A rack 2 is fixedly connected to the side wall of the guide rail 1. The gear 5 and the rack 2 mesh and contact each other.

[0030] Start motor 4 to drive gear 5 to rotate. Gear 5 rolls on the surface of rack 2, causing sliding sleeve 3 to move linearly on the surface of guide rail 1. This adjusts the position of nozzle 10 and nozzle 21, making it easier to clean different parts of the solar panel and thus expanding the cleaning area. It should be emphasized that the movement range of nozzle 10 and nozzle 21 can completely cover the longitudinal length of the solar panel.

[0031] Reference Figure 2 A base frame 13 is fixedly connected to the lower end of the guide rail 1, which can support the guide rail 1 and keep it stable. A roller 14 is fixedly installed at the bottom of the base frame 13. The roller 14 can realize the overall movement of the device, making it convenient to move to the working position for cleaning the solar panel.

[0032] This cleaning device is equipped with a positioning system and an intelligent driving system to obtain its current location in real time, enabling it to navigate autonomously based on a predetermined path or real-time conditions. The system uses sensors, cameras, lidar, and other technologies to perceive the environment, providing the cleaning device with real-time environmental information, which is then compared with a preset path to automatically adjust the driving direction.

[0033] Since the solar panels of a photovoltaic power station are placed in basically fixed positions and are arranged in neat rows or columns, the intelligent driving system of this device does not need to have a high level of intelligence. The cleaning device can also meet the needs of this device by being able to travel in a straight line along a row or column and position itself to perform blowing and sweeping.

[0034] The above-mentioned intelligent driving system is existing technology and will not be described in detail here. This photovoltaic cleaning device uses a battery to power the air pump 8, roller 14, motor 4, and cylinder 12, and drives the roller 14 through the electric motor; the electric motor has the advantages of fast response, high efficiency, and low noise.

[0035] Reference Figure 2 and 3 The guide rail 1 has a T-shaped cross section, and the slide sleeve 3 has a T-shaped sliding opening inside, which realizes the linear guidance of the slide sleeve 3 and prevents the slide sleeve 3 from detaching from the guide rail 1; and the surface of the guide rail 1 can be polished to minimize the wear of the slide sleeve 3 during the movement.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
