Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cleaning, in particular to a photovoltaic cleaning device capable of supporting walking on a large slope. Background Art

[0002] In photovoltaic power stations, bridges are usually set up between different photovoltaic panels in the same row to create passage conditions for cleaning robots and save the number of cleaning robots used. However, there are angular deviations, horizontal deviations, and front-to-back errors between photovoltaic panels of different arrays. For example, in photovoltaic power stations that use tracking brackets, different tracking brackets have different drives, which may cause front-to-back errors and horizontal deviations during installation. There is also a certain angle of torsion between the two ends of the tracking bracket and the drive. As a result, the connecting bridge between the two photovoltaic bracket arrays presents a state of one end uphill and the other end downhill. When the cleaning robot passes through the bridge, it is more likely to get stuck or detach from the frame of the photovoltaic panel, seriously affecting the smooth implementation of the cleaning work.

[0003] The existing publication number CN117220586 A, "A twisting photovoltaic cleaning robot with adjustable running posture", provides a solution for the photovoltaic cleaning robot to twist while walking, but in this technical solution, the photovoltaic cleaning robot includes two structures. The first one: there is no mounting cover, and the cleaning roller brush is directly set in the upper assembly and the lower assembly. This method will cause the cleaning roller brush to be exposed to the sun for a long time, and the sunlight rays will reduce the service life of the bristles of the cleaning roller brush; the second one: a mounting cover is set above the cleaning roller brush, and the mounting cover also needs to be connected to the upper assembly and the lower assembly through a connecting shaft, and under this connection method of the mounting cover, when the upper assembly and the lower assembly are twisted, there is still a problem of the mounting cover getting stuck.

The first connecting side plate 32 and the second connecting side plate are respectively arranged at two ends of the connecting main frame 33. The first connecting side plate 32 has a first connecting groove 321 and a first rotating hole 322. The first rotating shaft 13 and the first connecting side plate 32 are slidably connected in the first connecting groove 321.

[0049] In this embodiment, the first walking component 1 is also the upper module in the photovoltaic cleaning device, the second walking component 2 is also the lower module in the photovoltaic cleaning device, and the cleaning component 3 is also the cleaning roller brush 31 and related components in the photovoltaic cleaning device. The specific structure of the above components can be understood by referring to the commercially available photovoltaic cleaning devices.

[0050] Specifically, in some embodiments, the first walking component 1 also includes a first driving unit and a first walking wheel group, the first driving unit is arranged on the first frame 11; the first walking wheel group is arranged on the first frame 11, and the output end of the first driving unit is transmission connected with the first walking wheel group; wherein, the first driving unit can be a servo motor, and the first walking wheel group includes at least two first walking wheels 14, the two first walking wheels 14 are transmission connected with the output end of the first driving unit, the first walking wheel 14 is in contact with the upper surface of the photovoltaic panel, and the first driving unit drives the first walking wheel 14 to rotate, and can drive the first walking component 1 to rotate relative to the photovoltaic panel by means of friction.

[0051] Optionally, the first walking assembly 1 further includes a hanging wheel group, which is arranged on the first frame 11 and is drivingly connected to the output end of the first driving unit. The hanging wheel group includes at least two hanging wheels 15 arranged in parallel, and the hanging wheels 15 are drivingly connected to the first driving unit. The hanging wheels 15 and the first walking wheel 14 can be as follows: Figure 2 In the structural arrangement shown, the hanging wheel 15 corresponds to the outer side wall of the photovoltaic panel, that is, the hanging wheel 15 can move relatively along the outer side wall of the photovoltaic panel to enable the first traveling component 1 to travel on the photovoltaic panel.

[0052] Similarly, in some embodiments, the second walking assembly 2 further includes a second driving unit and a second walking wheel set, the second driving unit is arranged on the second frame; the second walking wheel set is arranged on the second frame, and the output end of the second driving unit is connected to the second walking wheel set in a transmission manner.

[0053] In this embodiment, the first walking component 1 and the second walking component 2 can be equipped with driving devices separately. When the photovoltaic cleaning device is twisted, the first walking component 1 can be driven separately and the second walking component 2 can also be driven separately to reduce the probability of the entire photovoltaic cleaning device getting stuck during the twisting process.

[0054] Furthermore, the first walking assembly 1 also includes a first frame 11, a first connecting shaft 12 and a first rotating shaft group, wherein the first frame 11 can be understood as a component that plays a supporting role in the first walking assembly 1, and the first connecting shaft 12 is movably connected to the first frame 11, that is, the first connecting shaft 12 can be connected to the first frame 11 through a bearing, and the first connecting shaft 12 can rotate relative to the first frame 11, and the first connecting shaft 12 is connected to the roller of the cleaning roller brush 31 through a transmission, which can be specifically achieved by pin locking, universal coupling, etc. The first rotating shaft group includes at least one first rotating shaft 13, and the first rotating shaft 13 is fixedly connected to the first frame 11; it can be understood that in some preferred embodiments, the number of the first rotating shaft 13 can be multiple. In this embodiment, the first rotating shaft 13 and the first connecting shaft 12 both protrude toward the side where the cleaning assembly 3 is located.

[0055] The second walking component 2 also includes a second frame, a second rotating axis group and a second connecting axis. The second rotating axis group includes at least one second rotating axis. A second rotating axis and a first rotating axis 13 can be set correspondingly, and the second connecting axis and the first connecting axis 12 are set correspondingly. The specific structure distribution of the first walking component 1 can be referred to for understanding.

[0056] The cleaning assembly 3 includes a cleaning roller brush 31, a first connecting side plate 32, a second connecting side plate and a connecting main frame 33, wherein the roller shaft of the cleaning roller brush 31 is provided with cleaning bristles on the outside, and the cleaning roller brush 31 can be rotated under the drive of the driving unit so that the bristles contact the upper surface of the photovoltaic panel, thereby removing dirt or impurities on the photovoltaic panel. The cleaning roller brush 31 is arranged between the first walking assembly 1 and the second walking assembly 2, and the roller shaft of the cleaning roller brush 31 is connected to the first connecting shaft 12 by transmission with the first walking assembly 1, and the roller shaft of the cleaning roller brush 31 is connected to the second walking assembly 2 by transmission with the second connecting shaft.

[0057] Furthermore, the connecting main frame 33 shown in this embodiment is arranged above the cleaning roller brush 31, and the connecting main frame 33 can provide a top cover for the cleaning roller brush 31 to reduce the probability of direct sunlight on the cleaning roller brush 31. At the same time, other required components, such as sensors, etc., can be arranged on the connecting main frame 33 according to actual needs to increase the use function of the entire photovoltaic cleaning device. The first connecting side plate 32 and the second connecting side plate are correspondingly arranged at both ends of the connecting main frame 33. The first connecting side plate 32 is movably connected to the roller shaft of the cleaning roller brush 31, and the first connecting side plate 32 is also movably connected to the first rotating shaft 13. Similarly, the second connecting side plate is movably connected to the roller shaft of the cleaning roller brush 31, and the second connecting side plate is also movably connected to the second rotating shaft.

[0058] Specifically, the first connecting side plate 32 is provided with a first connecting slot 321 and a first rotating hole 322. The first rotating hole 322 is coaxially arranged with the roller shaft of the cleaning roller brush 31, that is, the roller shaft of the cleaning roller brush 31 can pass through the first rotating hole 322 and then be connected to the first connecting shaft 12. The first rotating shaft 13 protrudes out of the first frame 11 and is placed in the first connecting slot 321. When the first walking component 1 is twisted, the first rotating shaft 13 moves in the first connecting slot 321 relative to the first connecting side plate 32. The end of the first connecting slot 321 is also the limit position of the movement of the first rotating shaft 13, which corresponds to the limit position of the twisting of the first walking component 1.

[0059] In this embodiment, this layout can achieve that when the first walking component 1 is twisted, the connection main frame 33 and the cleaning roller brush 31 always maintain a stable relative position relationship. Similarly, when the second walking component 2 is twisted, it also has this effect. When both the first walking component 1 and the second walking component 2 are twisted, the connection main frame 33 and the cleaning roller brush 31 always maintain a relatively fixed connection relationship. The connection between the entire connection main frame 33 and the first walking component 1 and the second walking component 2 is more flexible, and the connection main frame 33 always maintains a coaxial twisting relationship with the cleaning roller brush 31, which greatly reduces the problem of the connection main frame 33 getting stuck during the twisting process.

[0060] See also Figure 3 and Figure 4 In some embodiments, the first connecting groove 321 is an arc-shaped groove with a first preset length, the first connecting groove 321 has a first curvature, and the first connecting side plate 32 can rotate by a first preset angle relative to the first rotation axis 13; the second connecting groove is an arc-shaped groove with a second preset length, the second connecting groove has a second curvature, and the second connecting side plate can rotate by a second preset angle relative to the second rotation axis.

[0061] In this embodiment, the first connecting slot 321 is an arc slot having a first preset length. Figure 4 In some embodiments, the radial cross section of the main frame 33 is an arc structure. The radial cross section of the main frame 33 can also be made into an arc shape, making the overall shape more beautiful and generous.

[0062] The first preset length corresponds to the first arc, that is, the first preset length can be set according to actual needs, and the setting of the first preset length also changes the first arc synchronously. This actual need can be set from the maximum torsion angle that the photovoltaic cleaning device may encounter. Similarly, the second connecting chute can also be an arc chute, and the second connecting chute has a second arc. It can be understood that the first arc and the second arc can be different. For example, in some application scenarios, the torsion angle of the bridge corresponding to the first walking component 1 is 60 degrees, and the torsion angle of the bridge corresponding to the second walking component 2 is 30 degrees. In this case, the first arc and the second arc can be changed to the corresponding torsion angle values.

[0063] It should also be noted that the first connecting side plate 32 can rotate relative to the first rotating shaft 13 by a first preset angle, and the first connecting side plate 32 and the first rotating shaft 13 are in a mutually movable relationship. The first preset angle may not be the same as the first arc. In other words, the first preset angle is distinguished by direction and can have positive and negative angle values. The first arc is always positive and has no direction distinction. Similarly, the second preset angle and the second arc are two different concepts.

[0064] In some embodiments, the first arc is 45 degrees, and the first preset angle is ±22.5 degrees; the second arc is 45 degrees, and the second preset angle is ±22.5 degrees. For example, clockwise rotation is a positive value, and counterclockwise rotation is a negative value, then the first rotation axis 13 rotates +22.5 degrees, and the second rotation axis rotates -22.5 degrees, then the torsion angle between the first walking component 1 and the second walking component 2 is 45 degrees. The angle values ​​shown in this embodiment can meet the torsion requirements between the connecting bridges on the photovoltaic panels with large slopes.

[0065] See also Figure 2 and Figure 3In some embodiments, the number of the first rotation axes 13 is two, and the two first rotation axes 13 are arranged in parallel on the first frame 11; the number of the second rotation axes is two, and the two second rotation axes are arranged in parallel on the second frame.

[0066] The two first rotating shafts 13 can strengthen the connection stability between the first connecting side plate 32 and the first walking component 1. There are two supporting points between the first connecting side plate 32 and the first walking component 1. At the same time, when the first rotating shaft 13 rotates, one first rotating shaft 13 will only be impacted by the end point of the first connecting slot 321 in a single direction, thereby extending the service life of the first rotating shaft 13. Similarly, the two second rotating shafts can strengthen the connection stability between the second connecting side plate and the second walking component 2. There are two supporting points between the second connecting side plate and the second walking component 2. At the same time, when the second rotating shaft rotates, one second rotating shaft will only be impacted by the end point of the second connecting slot in a single direction, thereby extending the service life of the second rotating shaft.

[0067] In some embodiments, the first connecting shaft 12 is disposed on the central axes of the two first rotating shafts 13 , and the second connecting shaft is disposed on the central axes of the two second rotating shafts.

[0068] In some embodiments, the cleaning assembly 3 further includes a third driving unit 34 , which is disposed on the first frame 11 or the second frame, and an output end of the third driving unit 34 is drivingly connected to a roller shaft of the cleaning roller brush 31 .

[0069] In this embodiment, the third drive unit 34 is a drive device for driving the cleaning roller brush 31 to rotate, and can be a servo motor. Specifically, the third drive unit 34 can be arranged on the first walking assembly 1, or the third drive unit 34 can be arranged on the second walking assembly 2, and this embodiment does not limit this. In some embodiments, when the third drive unit 34 is arranged on the first frame 11, the third drive unit 34 is connected to the roller shaft of the cleaning roller brush 31 through the first connecting shaft 12; or when the third drive unit 34 is arranged on the second frame, the third drive unit 34 is connected to the roller shaft of the cleaning roller brush 31 through the second connecting shaft.
