DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application and are not used to limit the present application. In the present application, unless otherwise stated, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0029] The present application provides a cleaning robot, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0030] See also Figure 1 The present application provides a cleaning robot for cleaning the inclined surface of an object to be cleaned (the photovoltaic panel is used as an example in this embodiment). When a plurality of photovoltaic panels are arranged to form a photovoltaic panel array, metal frames are provided at the edges of adjacent photovoltaic panels. In the present application, the photovoltaic panel array is formed by arranging one or two photovoltaic panels into a unit along their length, and then arranging the above units along the width direction of the photovoltaic panel.

[0031] See also Figure 1 The cleaning robot includes a vehicle body 100, which can move on an array of photovoltaic panels, and the moving direction of the vehicle body 100 is defined as the front. At the same time, a cleaning system, a driving system and a pipeline system are arranged inside or outside the vehicle body 100.

[0032] The driving system is used to adjust the moving direction and speed of the vehicle body 100 on the photovoltaic panel. The cleaning system can clean the surface of the photovoltaic panel while the vehicle body 100 is moving. The pipeline system is used to spray cleaning liquid (such as water or cleaning liquid, etc.) onto the surface of the photovoltaic panel and cooperate with the cleaning system to clean the surface of the photovoltaic panel.

[0033] The drive system includes two sets of track devices, which are symmetrically arranged on both sides of the vehicle body 100. Each track device includes a wheel body, a track and a drive motor. The track is wound around the outside of the wheel body, and the drive motor is used to drive the wheel body to rotate and drive the track to move along the surface of the photovoltaic panel.

[0034] See also Figure 1 and Figure 4 The cleaning system includes a cleaning shell 600, a roller brush 610 and a cleaning motor. The cleaning shell 600 is a cylindrical object. The outer wall of the cleaning shell 600 is connected to the front side of the vehicle body 100. In the present application, the cleaning shell 600 is rotatably connected to the vehicle body 100 so that the cleaning shell 600 has a certain floating range to improve the cleaning effect and obstacle crossing ability of the cleaning system.

[0035] See also Figure 1 and Figure 3 Two mounting arms 110 are symmetrically arranged on the front side of the vehicle body 100 about its center line, and each mounting arm 110 is provided with a first pin hole 111 and a second pin hole 112. In the present application, the second pin hole 112 is located below the first pin hole 111. Two extension arms 630 are correspondingly arranged on the rear side wall of the cleaning housing 600, and each extension arm 630 is L-shaped. One end of the extension arm 630 is connected to the side wall of the cleaning housing 600 by a fastening screw, so that the extension arm 630 is fixedly connected to the cleaning housing 600; the other end of the extension arm 630 is provided with a third pin hole 631 and a fourth pin hole 632 along the thickness direction thereof, and correspondingly, the fourth pin hole 632 is located below the third pin hole 631.

[0036] When the end of the extending arm 630 is in contact with the mounting arm 110, and the first pin hole 111 is aligned with the third pin hole 631, and the second pin hole 112 is aligned with the fourth pin hole 632, the first pin shaft 710 can be inserted into the first pin hole 111 and the third pin hole 631, so that the cleaning shell 600 can rotate relative to the vehicle body 100; at the same time, the second pin shaft 720 can be detachably inserted into the second pin hole 112 and the third pin hole 631.

[0037] Since the first pin shaft 710 is always inserted into the first pin hole 111 and the third pin hole 631, the cleaning shell 600 can rotate at an angle around the first pin shaft 710, so that the cleaning shell 600 has a certain floating range, so that the roller brush 610 can always contact the surface of the photovoltaic panel to improve the cleaning effect; at the same time, the roller brush 610 can be lifted by obstacles such as the frame and cross the obstacle during movement, thereby increasing the obstacle-crossing ability of the cleaning system.

[0038] See also Figure 1 and Figure 3 When the second pin shaft 720 is inserted into the second pin hole 112 and the fourth pin hole 632, the first pin shaft 710 and the second pin shaft 720 jointly exert a force to fix the cleaning housing 600 and the vehicle body 100 relatively. When the second pin shaft 720 is pulled out, the cleaning housing 600 and the vehicle body 100 are rotatably connected only through the first pin shaft 710.

[0039] See also Figure 1-Figure 4 When the cleaning robot moves on the surface of the photovoltaic panel, the second pin shaft 720 is pulled out from the second pin hole 112 and the fourth pin hole 632, so that the cleaning shell 600 is rotatably connected to the vehicle body 100 through the first pin shaft 710, thereby improving the moving and obstacle crossing performance of the cleaning robot. When the cleaning robot is not in use, the second pin shaft 720 is inserted into the second pin hole 112 and the fourth pin hole 632, so that the cleaning shell 600 is lifted to a certain height and remains fixed relative to the vehicle body 100, thereby avoiding the influence of gravity that causes the bristles on the lower side of the roller brush 610 to be squeezed, so as to ensure the cleaning effect of the roller brush 610. At the same time, after the cleaning shell 600 is relatively fixed to the vehicle body 100, it can be avoided that the position of the roller brush 610 swings randomly during the process of picking, transporting, and storing.

[0040] See also Figure 1-Figure 4 The bottom wall of the extending arm 630 is provided with a limiting groove 633, and the surface of the mounting arm 110 is correspondingly provided with a limiting pin 113, which is matched with the limiting groove 633. When the limiting pin 113 is inserted into the limiting groove 633, the cleaning housing 600 rotates to the limit position, thereby ensuring that the roller brush 610 is lifted to a certain height by the cleaning housing 600 during the movement, so as to avoid interference between the roller brush 610 and the photovoltaic panel.

[0041] See also Figure 4 The roller brush 610 is installed in the cleaning housing 600 along its axial direction, and the two ends of the roller brush 610 are connected to the two ends of the cleaning housing 600 through rolling bearings, so that the roller brush 610 is rotatably connected to the cleaning housing 600. At the same time, a cleaning motor is provided at one end of the cleaning housing 600, and the extended shaft of the cleaning motor is connected to the end of the roller brush 610 to drive the roller brush 610 to rotate.

[0042] See also Figure 4 and Figure 5 A support frame 620 is provided in the middle of the cleaning housing 600, the support frame 620 is connected to the side wall of the cleaning housing 600 by fastening screws, and the top of the support frame 620 is in contact with the inner side wall of the cleaning housing 600. The support frame 620 can apply a supporting force to the cleaning housing 600, thereby increasing the strength of the cleaning housing 600 and reducing the deformation of the cleaning housing 600.

[0043] The middle part of the support frame 620 includes an assembly hole, and the roller brush 610 passes through the assembly hole, so that the middle part of the roller brush 610 is rotatably connected to the support frame 620 through a rolling bearing. The support frame 620 applies a supporting force to the roller brush 610, which can increase the stability of the roller brush 610 during cleaning and improve the cleaning effect; at the same time, it can also reduce the deformation of the roller brush 610 during long-term use, ensuring the accuracy and stability of the assembly of the roller brush 610 and the cleaning housing 600.

[0044] See also Figure 5 and Figure 6 The top of the support frame 620 is concave to form a slot 621. Since the top of the support frame 620 is in contact with the inner wall of the cleaning shell 600, the cleaning shell 600 can close the top of the slot 621, making the slot 621 a through channel.

[0045] See also Figure 1 , Figure 4 and Figure 8 The pipeline system includes a rotary joint 200, a support arm 310, a water inlet pipe 300, a water delivery pipe and at least one nozzle 530. The rotary joint 200 is connected to the top of the vehicle body 100 and includes a liquid inlet and a liquid outlet. One end of the water inlet pipe 300 is connected to the liquid inlet, and the other end thereof can be connected to an external water delivery system. At the same time, multiple nozzles 530 are connected to the water delivery pipe and can be connected to the liquid outlet of the rotary joint 200 through the water delivery pipe.

[0046] By using the water inlet pipe 300 to connect the water delivery system, the existing water tank design can be simplified, the weight of the cleaning robot can be reduced, and the power consumption rate during cleaning can be reduced, thereby improving the cleaning efficiency; at the same time, the cleaning robot can be reduced from slipping and falling due to weight and inertia when moving and turning, thereby ensuring the safety and stability of its work. At the same time, by using the rotary joint 200 to connect the water inlet pipe 300 and the water delivery pipe, the water inlet pipe 300 can be prevented from getting entangled when the cleaning robot moves and turns.

[0047] See also Figure 1 , Figure 7 and Figure 8The rotary joint 200 includes a bottom plate 210, a mounting seat 220, a joint body 230, an L-shaped tube 240 and a pipe joint 250. The bottom plate 210 is connected to the top of the vehicle body 100 by fastening screws. At the same time, the bottom plate 210 is bent away from the vehicle body 100 to form two protrusions 211. The two sides of the mounting seat 220 are connected to the two protrusions 211 by fastening screws, so that the protrusions 211 can assist the mounting seat 220 to lift a certain height. The joint body 230 is fixedly connected to the top of the mounting seat 220. The mounting seat 220 is provided with a receiving cavity inside. The L-shaped tube 240 is arranged in the receiving cavity. One end of the L-shaped tube 240 is connected to the bottom end of the joint body 230, and the other end thereof is connected to the water pipe. One end of the pipe joint 250 is rotatably connected to the top of the joint body 230, and the other end thereof is connected to the water inlet pipe 300.

[0048] The cleaning liquid in the external water supply system flows into the water inlet pipe 300, and passes through the pipe joint 250, the joint body 230 and the L-shaped pipe 240 in sequence, and then flows into the water supply pipe, so that multiple nozzles 530 spray the cleaning liquid in the water supply pipe onto the surface of the photovoltaic panel.

[0049] See also Figure 1 and Figure 8 The outer wall of the rotary joint 200 is rotatably provided with a support arm 310, which is a square tube structure. One end of the support arm 310 is provided on the outer wall of the joint body 230, and the other end thereof extends in a direction away from the vehicle body 100. The side wall of the support arm 310 is provided with a mounting groove 311, and one end of the water inlet pipe 300 can pass through the mounting groove 311 and be inserted into the support arm 310. In the present application, there is a maximum distance between the rotary joint 200 and the end of the vehicle body 100, and the length of the support arm 310 is greater than the maximum distance.

[0050] The support arm 310 is a rigid structure, and part of the water inlet pipe 300 can be inserted into the support arm 310, so that the support arm 310 can be used to lift the end of the water inlet pipe 300 above the vehicle body 100 to avoid interference between the vehicle body 100 and the water inlet pipe 300 during the movement of the cleaning robot.

[0051] See also Figure 1 , Figure 4 and Figure 8The water delivery pipe includes a first pipe body 510 and a second pipe body 520, wherein one end of the first pipe body 510 is connected to the end of the L-shaped pipe 240, and the other end thereof is inserted into the cleaning housing 600 and connected to the middle of the second pipe body 520 along the slot 621 of the support frame 620. The two ends of the second pipe body 520 are respectively connected to the two end surfaces of the cleaning housing 600, so that the second pipe body 520 is relatively fixed to the cleaning housing 600, and the central axis of the second pipe body 520 is parallel to the central axis of the cleaning housing 600.

[0052] The second tube body 520 is disposed at the front side of the roller brush 610, and the aforementioned multiple nozzles 530 are all connected to the second tube body 520 and can be arranged along the axial direction of the second tube body 520. The water outlet of the nozzle 530 is disposed toward the front side of the roller brush 610, and the multiple nozzles 530 are used to spray cleaning liquid onto the surface of the photovoltaic panel, thereby improving the cleaning effect of the cleaning robot.

[0053] See also Figure 1-Figure 4 The front side of the vehicle body 100 is provided with a scraper 400, the bottom of which can be attached to the surface of the photovoltaic panel, and the scraper 400 can remove the cleaning liquid attached to the photovoltaic panel. At the same time, the roller brush 610 and the cleaning shell 600 have a certain floating range during the movement, so the scraper 400 arranged on the front side of the vehicle body 100 can always be attached to the surface of the photovoltaic panel during the movement, thereby ensuring the cleaning effect of the cleaning robot.

[0054] See also Figure 1 and Figure 2 The scraper 400 includes a mounting frame 410, a first plate 420, a second plate 430 and a partition 440. The top of the mounting frame 410 is connected to the front side of the vehicle body 100 by fastening screws, so that the scraper 400 is relatively fixed to the vehicle body 100. The bottom of the mounting frame 410 is concave to form a mounting groove. The top of the first plate 420, the top of the second plate 430 and the top of the partition 440 are all arranged on the bottom wall of the mounting groove, and the partition 440 is located between the first plate 420 and the second plate 430, and is used to separate the first plate 420 and the second plate 430.

[0055] The center plane of the first plate body 420 is parallel to the center plane of the second plate body 430, and the bottom ends of the first plate body 420 and the second plate body 430 are both inclined at an angle toward the vehicle body 100, so that the first plate body 420 and the second plate body 430 are inclined along the moving direction when the vehicle body 100 is moving, which can not only improve the cleaning effect of the scraper 400, but also avoid interference between the scraper 400 and obstacles when the vehicle body 100 is moving over obstacles.

[0056] The bottom end of the first plate 420 is a slope, and the bottom end of the second plate 430 is also a slope. Therefore, when the vehicle body 100 moves, the bottom ends of the first plate 420 and the second plate 430 can be attached to the surface of the photovoltaic panel to improve the cleaning effect of the cleaning robot.

[0057] See also Figure 1 and Figure 4 The length of the roller brush 610 is adapted to the width of at least one photovoltaic panel. The length of the cleaning side in the present application matches the unit formed by the photovoltaic panels arranged along the length direction, so that when the cleaning robot moves along the width direction of the photovoltaic panel, it can clean the entire photovoltaic panel array, avoiding the cleaning robot from turning back and forth, thereby improving the cleaning efficiency.

[0058] See also Figure 1 A warning light 120 is provided at the top of the vehicle body 100 to assist in indicating the position of the cleaning robot, thereby improving the convenience of using the cleaning robot.
