Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning robots, and specifically relates to a robot for cleaning photovoltaic panels. Background Art

[0002] A photovoltaic panel cleaning robot is a robot device that can autonomously clean the dust and dirt on the surface of photovoltaic panels. Compared with the traditional manual cleaning method, the photovoltaic panel cleaning robot has the advantages of high efficiency, time saving, safety, reliability, etc., and thus has been widely used in the photovoltaic industry.

[0003] Photovoltaic panels are usually set up on a large scale in remote areas. Mainly aiming at the problems of photovoltaic panels set up in mountainous and barren areas, the mountain body may be affected by certain factors (such as collapse, differential weathering, precipitation, water flow scouring, earthquake, etc.). After the gravel becomes unstable from the surface of the geological body, it will fall on the photovoltaic panels, affecting the normal operation of the photovoltaic panels. The existing photovoltaic panel cleaning robots have the following deficiencies in the use process, such as:

[0004] There is a lack of obstacle clearing effect for foreign objects on the photovoltaic panels. The volume of the gravel is larger than that of the dust and cannot be cleaned by the dust suction mechanism set on the robot, which will block the driving route of the robot and lead to poor cleaning effect of the robot.

[0005] Therefore, a robot for cleaning photovoltaic panels is proposed to solve the above-mentioned problems. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a robot for cleaning photovoltaic panels, which has the advantages of being able to clear obstacles for gravel, etc., and solves the problem that the existing photovoltaic panel cleaning robots lack the obstacle clearing effect for foreign objects on the photovoltaic panels, resulting in the gravel blocking the driving route of the robot and leading to poor cleaning effect of the robot.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A robot for cleaning photovoltaic panels includes a robot body for cleaning photovoltaic panels and a terminal device. A limiting cylinder is fixedly connected to the top of the robot body for cleaning photovoltaic panels. A limiting rod is slidably connected inside the limiting cylinder. A tripod is fixedly connected to the top of the limiting rod. A transmission column is rotatably connected inside the tripod. A clearing belt is externally meshed with the transmission column. Clearing strips are fixedly connected to the outside of the clearing belt.

[0008] Furthermore, the number of the limiting cylinder, the limiting rod, the tripod and the clearing belt is two and they are symmetrically distributed left and right. The number of transmission columns on each tripod is three and they are respectively distributed at three corners inside the tripod.

[0009] Further, the number of the obstacle clearing strips is greater than ten and they are evenly distributed on the obstacle clearing belt, and the two obstacle clearing belts are meshed with each other through the obstacle clearing strips.

[0010] Further, a return spring is fixedly connected to the inner bottom of each of the two limiting cylinders, the top of the return spring is fixedly connected to the limiting rod, and a displacement sensor is arranged at the inner bottom of each of the two limiting cylinders, and the displacement sensor is located directly below the limiting rod.

[0011] Further, a motor is arranged inside the robot body for cleaning the photovoltaic panel, a first gear is fixedly connected to the output shaft of the motor, a transmission belt is meshed outside the first gear, a second gear is fixedly connected to the front side of the transmission column, and the outside of the second gear is meshed with the transmission belt.

[0012] Further, the output shaft of the motor penetrates through the housing of the robot body for cleaning the photovoltaic panel, and the output shaft of the motor is rotatably connected to the housing of the robot body for cleaning the photovoltaic panel.

[0013] Further, a signal transceiver is fixedly connected to the front side of the robot body, the displacement sensor and the signal transceiver are electrically connected through a wire, and the signal transceiver is wirelessly connected to the terminal device.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] For the robot for cleaning the photovoltaic panel, the motor drives the first gear, the transmission belt, the second gear and the transmission column to rotate, the transmission column drives the obstacle clearing belt and the obstacle clearing strips to rotate, and the obstacle clearing strips push the gravel outside the moving route of the robot body for cleaning the photovoltaic panel, preventing the gravel from blocking the driving route of the robot body for cleaning the photovoltaic panel. When the robot contacts a relatively large gravel, the tripod and the limiting rod move towards the robot body for cleaning the photovoltaic panel due to the reaction force, the displacement sensor monitors the position change of the limiting rod and transmits the data to the terminal device through the signal transceiver, prompting the user that there is large-volume gravel on the photovoltaic panel so as to take corresponding measures.

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3 , an embodiment provided by the present invention:

[0022] A robot for cleaning photovoltaic panels includes a robot body 1 for cleaning photovoltaic panels and a terminal device 15. A limit cylinder 2 is fixedly connected to the top of the robot body 1 for cleaning photovoltaic panels. A limit rod 3 is slidably connected inside the limit cylinder 2. The top of the limit rod 3 is fixedly connected to a tripod 4. A transmission column 5 is rotatably connected inside the tripod 4. A clearing belt 6 is meshed with the outside of the transmission column 5. A clearing strip 7 is fixedly connected to the outside of the clearing belt 6.

[0023] Further, the robot body 1 for cleaning photovoltaic panels can clean the dust on the photovoltaic panels. The limit cylinder 2 is slidably connected to the limit rod 3 to maintain the stability of the limit rod 3. The limit rod 3 is fixedly connected to the tripod 4 to maintain the stability of the tripod 4.

[0024] Further, the tripod 4 is rotatably connected to the transmission column 5 to maintain the stability of the transmission column 5. The transmission column 5 is meshed with the clearing belt 6, so that when the transmission column 5 rotates, it can drive the clearing belt 6 to rotate. The clearing belt 6 is fixedly connected to the clearing strip 7, so that when the clearing belt 6 rotates, it can drive the clearing strip 7 to rotate.

[0025] Further, when the clearing strip 7 contacts the gravel during rotation, it can push the gravel to both sides of the robot body 1 for cleaning photovoltaic panels, and push the gravel outside the moving route of the robot body 1 for cleaning photovoltaic panels to prevent the gravel from blocking the moving route of the robot body 1 for cleaning photovoltaic panels.

[0026] Furthermore, there is a certain gap between the obstacle clearing belt 6 and the photovoltaic panel, and they do not contact each other, preventing the dust from being pushed away and affecting the cleaning of dust by the robot body 1 for cleaning the photovoltaic panel. Moreover, the two obstacle clearing belts 6 are engaged with each other through an obstacle clearing strip 7, enabling the two obstacle clearing belts 6 to rotate synchronously and in opposite directions.

[0027] Furthermore, the reset spring 8 can play a buffering role when the robot contacts larger gravel, preventing the robot from being damaged due to collision with the larger gravel. The displacement sensor 9 is located directly below the limit rod 3 to monitor the position of the limit rod 3 in real time.

[0028] Furthermore, the output shaft of the motor 10 is fixedly connected to the first gear 11, so that the motor 10 can drive the first gear 11 to rotate after starting. Both the first gear 11 and the second gear 13 are engaged with the transmission belt 12, enabling the first gear 11 to drive the second gear 13 to rotate when the first gear 11 rotates. The second gear 13 is fixedly connected to the transmission column 5, enabling the second gear 13 to drive the transmission column 5 to rotate synchronously when the second gear 13 rotates.

[0029] Furthermore, the terminal device 15 is wirelessly connected to the signal transceiver 14, and the signal transceiver 14 is electrically connected to the displacement sensor 9 through a wire, enabling the data monitored by the displacement sensor 9 to be transmitted to the terminal device through the signal transceiver 14.

[0030] Working principle: The motor 10 drives the first gear 11, the transmission belt 12, the second gear 13, and the transmission column 5 to rotate. The transmission column 5 drives the obstacle clearing belt 6 and the obstacle clearing strip 7 to rotate. The obstacle clearing strip 7 pushes the gravel outside the moving route of the robot body 1 for cleaning the photovoltaic panel. When the robot contacts larger gravel, the tripod 4 and the limit rod 3 move towards the robot body 1 for cleaning the photovoltaic panel due to the reaction force. The displacement sensor 9 monitors the position change of the limit rod 3 and transmits the data to the terminal device 15 through the signal transceiver 14, prompting the user that there is large-volume gravel on the photovoltaic panel so as to take corresponding measures, thereby achieving the effect of clearing obstacles for the gravel and solving the problem that the existing photovoltaic panel cleaning robot lacks the effect of clearing obstacles for foreign objects on the photovoltaic panel, resulting in the gravel blocking the driving route of the robot and poor cleaning effect of the robot.
