Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic cleaning technology, and in particular relates to an adjustable water spray device for photovoltaic cleaning equipment. Background Technology

[0002] With the continuous development and application of photovoltaic power generation technology and the widespread deployment of photovoltaic modules in various environments, photovoltaic cleaning has gradually become an important part of ensuring the efficient operation of photovoltaic systems. The surface of photovoltaic panels usually accumulates dust, sand, bird droppings, dirt, and other pollutants. The presence of these pollutants not only affects the light transmittance of photovoltaic modules but may also have adverse effects on their long-term operation. Therefore, it is crucial to clean photovoltaic modules regularly to maintain their high-efficiency power generation performance. Photovoltaic cleaning robots play an important role in the cleaning and maintenance of photovoltaic power plants. Existing photovoltaic cleaning robots are generally equipped with water spraying devices to wash away dust and dirt on the surface of photovoltaic panels through water flow, so as to maintain the high efficiency of photovoltaic panels and extend their service life.

[0003] However, existing photovoltaic cleaning robot water spraying devices generally have the following problems: Firstly, the rinsing angle is fixed. Current photovoltaic cleaning robots use fixed-angle water spraying devices, which lack flexibility and cannot adjust the angle of the rinsing nozzles according to the dust accumulation on the photovoltaic panel surface, resulting in reduced rinsing effectiveness. Secondly, they cannot automatically adjust the water volume. Existing water spraying systems can only provide a fixed water volume and cannot intelligently adjust it according to the degree of contamination of the photovoltaic panels. Since the nature of dirt and the degree of dust accumulation on different photovoltaic panel surfaces vary greatly, a fixed water volume often leads to water waste. For example, for slightly contaminated photovoltaic panels, using too much water for cleaning is not only ineffective but also wasteful of water resources; while for severely contaminated photovoltaic panels, a fixed water volume may not be sufficient for thorough cleaning, affecting the cleaning quality.

[0004] To address these issues, we provide an adjustable water spray device for photovoltaic cleaning equipment. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable water spray device for photovoltaic cleaning equipment. By combining the rinsing component and the adjustment component, it solves the problems of fixed rinsing angle, which leads to reduced rinsing effect and non-adjustable water volume, which leads to resource waste in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an adjustable water spray device for photovoltaic cleaning equipment, comprising a mobile robot with a walking track at its bottom and a cleaning roller on one side. A rinsing assembly is located on top of the cleaning roller, including a rinsing tank at the top of the cleaning roller, a rinsing pipe movably connected inside the rinsing tank via a bearing, and a nozzle connected to the bottom of the rinsing pipe. The rinsing assembly enables the rinsing of the photovoltaic panel surface. An adjustment assembly is located on top of the mobile robot, including a laser sensor at the top of the mobile robot, a delivery pipe at the top of the mobile robot, and a self-regulating valve connected to the surface of the delivery pipe. The adjustment assembly allows for the adjustment of the water spray volume.

[0008] The present invention is further configured such that there are two rinsing pipes, which are longitudinally staggered and distributed in the rinsing box.

[0009] The present invention is further configured such that a dual-axis motor is fixedly connected to one side of the rinsing tank, a rotating rod is fixedly connected to the output end of the dual-axis motor, a drive chain wheel is fixedly connected to the end of the rotating rod away from the dual-axis motor, the drive chain wheel is connected to a driven chain wheel through chain drive, and the driven chain wheel is fixedly connected to the surface of the rinsing pipe.

[0010] The present invention is further configured such that a support plate is fixedly connected to one side of the rinsing box, and a tilt sensor is fixedly connected to the top of the rinsing pipe.

[0011] The present invention is further configured such that a fixed plate is fixedly connected to the top of the mobile robot, and a hollow tube is fixedly connected to the top of the fixed plate by bolts. A water supply pipe is placed inside the hollow tube, one end of the water supply pipe is connected to a rotary joint, and the other end of the rotary joint is connected to an external delivery pump.

[0012] The present invention is further configured such that one end of the conveying pipe is connected to a three-way valve, and a flow sensor is fixedly connected inside the conveying pipe and on the side away from the three-way valve and the self-control valve.

[0013] The present invention is further configured such that a hose is connected to the top of the flushing pipe, and the top of the hose is connected to the delivery pipe.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model achieves real-time monitoring and precise response to the amount of dust accumulation on the surface of photovoltaic panels through an intelligent adjustment system integrating laser sensors and self-control valves. When a large amount of dust is detected, the system automatically opens the dual flushing pipes and links the dual-axis motor to drive the chain transmission mechanism, so that the nozzle angle is dynamically adjusted to the optimal flushing range of 15°-25°. At the same time, the three-way valve and flow sensor are matched with the optimal water pressure to form a multi-dimensional three-dimensional flushing mode. Compared with the traditional fixed-angle spraying method, this design effectively solves the problem of cleaning blind spots caused by the fixed angle of traditional equipment through the coordinated control of software and hardware.

[0016] 2. This utility model constructs a three-dimensional, fully covered flushing system by adopting a double-layer flushing pipe structure with an alternating upper and lower layout, combined with a vertically staggered nozzle array and real-time angle data fed back by an tilt sensor. When local contamination is detected, the single / double pipe switching can be achieved through an independent opening and closing self-control valve, and the nozzle pitch angle can be adjusted by a drive motor, thereby adjusting the water flow coverage area, ensuring the flushing effect while reducing resource consumption.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-4 This utility model is an adjustable water spray device for photovoltaic cleaning equipment, including a mobile robot 1, a walking track 2 at the bottom of the mobile robot 1, a cleaning roller 3 on one side of the mobile robot 1, and a rinsing assembly at the top of the cleaning roller 3. The rinsing assembly includes a rinsing box 4 at the top of the cleaning roller 3, a rinsing pipe 5 movably connected to the rinsing box 4 via a bearing, and a nozzle 6 connected to the bottom of the rinsing pipe 5. The rinsing assembly can rinse the surface of the photovoltaic panel. An adjustment assembly is set on the top of the mobile robot 1, including a laser sensor 7 at the top of the mobile robot 1. The laser sensor 7 can detect that the dust layer accumulated on the surface of the photovoltaic panel will affect the reflection of the laser beam. A thicker dust layer will weaken the intensity of the reflected light because the dust layer will absorb or scatter more laser beams. Therefore, the change in the intensity of the reflected light can reflect the degree of dust accumulation. A conveying pipe 8 is set on the top of the mobile robot 1, and a self-control valve 9 is connected to the surface of the conveying pipe 8. The adjustment assembly can adjust the water spray volume according to the amount of dust accumulation.

[0027] Example 2

[0028] Please see Figures 1-4Based on Example 1, two rinsing pipes 5 are arranged longitudinally and staggered within the rinsing tank 4. The two staggered rinsing pipes 5 improve the rinsing effect. A dual-axis motor 10 is fixedly connected to one side of the rinsing tank 4. A rotating rod 11 is fixedly connected to the output end of the dual-axis motor 10. A drive chain wheel 12 is fixedly connected to the end of the rotating rod 11 away from the dual-axis motor 10. The drive chain wheel 12 is connected to a driven chain wheel 13 via chain drive. The driven chain wheel 13 is fixedly connected to the surface of the rinsing pipes 5. The dual-axis motor 10 drives the drive chain wheel 12 and the driven chain wheel 13. The driven chain wheel 13 rotates, which in turn drives the flushing pipe 5 to rotate, adjusting the flushing angle of the nozzle 6. A support plate 14 is fixedly connected to one side of the flushing box 4, and a tilt sensor 15 is fixedly connected to the top of the flushing pipe 5. The rotating rod 11 is movably connected to the support plate 14 via a bearing. The support plate 14 supports the rotating rod 11. The tilt sensor 15 determines the rotation angle of the pipe by measuring the deviation of the pipe from the direction of gravity, thereby determining the tilt angle of the flushing pipe 5. The top of the mobile robot 1... A fixed plate 16 is fixedly connected, and a hollow tube 17 is bolted to the top of the fixed plate 16. A water supply pipe 18 is placed inside the hollow tube 17. One end of the water supply pipe 18 is connected to a rotary joint 19, and the other end of the rotary joint 19 is connected to an external delivery pump. The fixed plate 16 and the hollow tube 17 allow the delivery pipe 8 to be mounted on the top of the mobile robot 1. The water supply pipe 18 allows external flushing water to be delivered to the delivery pipe 8. The rotary joint 19 prevents the pipes from twisting together during movement. A three-way valve 20 is connected to one end of the delivery pipe 8. A flow sensor is fixedly connected inside the delivery pipe 8 and away from the three-way valve 20 and the self-control valve 9. The other end of the three-way valve 20 is connected to the water supply pipe 18. The three-way valve 20 can be used to divert the flushing water into the two delivery pipes 8. The flow sensor can detect the water flow inside the delivery pipe 8. A hose 21 is connected to the top of the flushing pipe 5. The top of the hose 21 is connected to the delivery pipe 8. The hose 21 is elastic. When the flushing angle of the flushing pipe 5 is adjusted, the flushing water can still be delivered normally due to the presence of the hose 21.

[0029] The working principle of this utility model is as follows: The mobile robot 1 moves on the surface of the photovoltaic panel via the walking track 2. During the movement, the laser sensor 7 detects the amount of dust on the surface of the photovoltaic panel. When the amount of dust on the surface of the photovoltaic panel is large, the self-control valves 9 on the surface of the two conveying pipes 8 are opened. At this time, the nozzles 6 at the bottom of the two flushing pipes 5 spray flushing water, and the dual-axis motor 10 is started. The dual-axis motor 10 drives the rotating rod 11 to rotate, the rotating rod 11 drives the drive chain wheel 12 to rotate, the drive chain wheel 12 drives the driven chain wheel 13 to rotate, and the driven chain wheel 13 drives the flushing pipe 5 to rotate. The flushing pipe 5 adjusts the flushing of the nozzles 6. The angle is adjusted so that the nozzle 6 is between 15° and 25° with the photovoltaic panel, so that the rinsing water sprayed by the nozzle 6 is evenly sprayed onto the surface of the photovoltaic panel within a certain range, thereby increasing the rinsing effect on dust. By increasing the water volume and adjusting the water angle, the cleaning effect can be improved when the amount of dust is large. When the amount of dust on the surface of the photovoltaic panel is small, one of the automatic control valves 9 is closed, and the rinsing work can be completed by using the nozzle 6 on the surface of a single rinsing pipe 5. The tilt angle between the rinsing pipe 5 and the photovoltaic panel is adjusted to increase the tilt angle, thereby increasing the spraying area. At this time, the water consumption can be reduced while meeting the cleaning effect.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
