Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic panel cleaning equipment, in particular to an anti-fall photovoltaic panel water circulation cleaning robot. Background Art

[0002] Photovoltaic panels are in outdoor environments all year round. Dust is easily adsorbed on the surface of the photovoltaic panels to form a dust layer, which affects the working efficiency of the photovoltaic panels. Therefore, the surface of the photovoltaic panels needs to be cleaned to ensure the working efficiency of the photovoltaic panels.

[0003] During the installation of photovoltaic panels, in order to achieve the best effect, the photovoltaic panels are generally installed at an angle. Although the cleaning equipment uses a large friction resistance during the cleaning process, the cleaning equipment will still slide and move during or after the photovoltaic panel cleaning process, affecting the use of the cleaning equipment and the cleaning efficiency of the photovoltaic panels.

[0004] Patent application number CN201711496164.8 proposes a curtain wall cleaning device based on rope parallel technology. The patent proposes to install retractable rope devices at the four corners of the wall, and install the cleaning equipment between the four ropes to achieve the movement of the cleaning equipment. However, in the background technology of this application, the photovoltaic panel does not have a place to retract and fix the four retractable ropes, so the technical solution in this document cannot solve the problem of sliding displacement of the current photovoltaic panel cleaning equipment during the cleaning process.

[0005] Patent application number CN200710047762.7 proposes a rope pulling device for an exterior wall cleaning machine. This patent tightens the rope to keep the cleaning equipment close to the cleaning surface to prevent the cleaning machine from rebounding. However, in the above-mentioned background technology, the cleaning of photovoltaic panels requires left and right and up and down movement. It can be seen in this application that it can only move up and down, not left and right. Therefore, the technical solution in this document cannot solve the problem of sliding displacement of current photovoltaic panel cleaning equipment during the cleaning process.

[0006] The technical problem to be solved by the utility model is to provide an anti-fall photovoltaic panel water circulation cleaning robot to solve the problem of sliding displacement in the current photovoltaic panel cleaning equipment during the cleaning process.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A water circulation cleaning robot for preventing photovoltaic panels from falling comprises a cleaning vehicle for cleaning the surface of the photovoltaic panels, a pendant arranged on the top of the photovoltaic panels, and a distance adjustment device arranged between the cleaning vehicle and the pendant, wherein the distance adjustment device is used to adjust the distance between the cleaning vehicle and the pendant.

One end of the wire rope is wound around the retractable reel, and the other end of the wire rope is fixedly connected to the positioning rod after passing around the positioning shaft.

[0010] Furthermore, a guide wheel is coaxially connected to the positioning shaft, and the other end of the wire rope is fixedly connected to the positioning rod after passing around the guide wheel.

[0011] Furthermore, the axis of the positioning shaft is perpendicular to the surface of the photovoltaic panel, and the axis of the positioning shaft and the axis of the reel are parallel.

[0012] Furthermore, the reciprocating motor is rotatably connected to the pendant.

[0013] Furthermore, the hanger includes a movable channel steel and rollers arranged on the movable channel steel. The movable channel steel cover is arranged on the top of the photovoltaic panel. The number of the rollers is at least three, and the rollers are evenly distributed on the three sides of the movable channel steel.

[0014] Furthermore, the pendant also includes a positioning switch and a positioning plate. There are two positioning switches and two positioning plates. The two positioning switches are respectively installed at the two ends of the movable channel steel, and the two positioning plates are respectively detachably connected to the two sides of the photovoltaic panel at the two ends of the movable channel steel.

[0015] Furthermore, the cleaning vehicle is provided with a controller for controlling the movement of the cleaning vehicle, and the controller is connected to the positioning switch signal.

[0016] Furthermore, the cleaning vehicle is provided with a power supply, the positioning shaft is provided with a conductive slip ring electrically connected to the power supply, and the reciprocating motor is electrically connected to the conductive slip ring.

One end of the cable is electrically connected to the conductive slip ring, and the other end of the cable is electrically connected to the retractable discharge motor and the drive motor. Both the retractable discharge motor and the drive motor are connected to the controller signal.

[0018] The significant beneficial effects achieved by this utility model are:

[0019] 1. This application stabilizes the cleaning vehicle on the surface of the photovoltaic panel by setting up a pendant and a distance adjustment device, preventing the cleaning vehicle from sliding along the inclined photovoltaic panel during the cleaning process, improving the cleaning efficiency and cleaning effect, and effectively solving the problem of sliding displacement of current photovoltaic panel cleaning equipment during the cleaning process.

[0020] 2. The setting of the guide wheel can avoid friction with the positioning shaft when the wire rope is retracted or released.

[0021] 3. The positioning axis and the axis of the reel are parallel and perpendicular to the surface of the photovoltaic panel, which can make the wire rope retract and release smoothly and prevent the wire rope from escaping from the guide wheel or the reel.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] Example 1

[0035] like Figures 1-4 As shown, a water circulation cleaning robot for preventing photovoltaic panels from falling comprises a cleaning vehicle 1 for cleaning the surface of the photovoltaic panels, a pendant mounted on the top of the photovoltaic panels, and a distance adjustment device mounted between the cleaning vehicle 1 and the pendant, the distance adjustment device being used to adjust the distance between the cleaning vehicle 1 and the pendant;

[0036] Specifically, the distance adjustment device includes a positioning rod 2, a retractable assembly and a positioning shaft 3. The positioning shaft 3 is vertically fixedly mounted on the upper end of the cleaning vehicle 1. The positioning rod 2 and the retractable assembly are both mounted on a hanger and are located on both sides of the positioning shaft 3. The retractable assembly includes a wire rope 4, a retractable motor 5 and a retractable reel 6. The retractable motor 5 and the retractable reel 6 are transmission-connected. The retractable reel 6 is driven to rotate by the rotation of the output shaft of the retractable motor 5. One end of the wire rope 4 is fixed and wound around the retractable reel 6. The other end of the wire rope 4 is fixedly connected to the positioning rod 2 after passing through the positioning shaft 3. The two ends of the wire rope 4 are V-shaped after being connected to the retractable reel 6 and the positioning rod 2 respectively.

[0037] In order to facilitate the reel 6 to retract and unreel the wire rope 4 and reduce the friction between the wire rope 4 and the positioning shaft 3, a guide wheel 7 is coaxially connected to the positioning shaft 3, and the other end of the wire rope 4 is fixedly connected to the positioning rod 2 after passing through the guide wheel 7 on the positioning shaft 3;

[0038] In this embodiment, in order to facilitate the steel wire rope 4 to restrain the cleaning vehicle 1, the axis of the positioning shaft 3 is perpendicular to the upper end of the cleaning vehicle 1 and perpendicular to the surface of the photovoltaic panel (working surface) when the cleaning vehicle 1 is working. The axis of the positioning shaft 3 and the axis of the reel 6 are parallel;

[0039] The hanger includes a movable channel steel 8 and a roller 9 rotatably installed on the movable channel steel 8. The movable channel steel 8 is covered at the top of the photovoltaic panel. There are at least three rollers 9, which are evenly distributed on the three sides of the movable channel steel 8. The rotation of the rollers 9 facilitates the movement of the movable channel steel 8 on the photovoltaic panel. By driving the roller 9 cover to be located at the top of the photovoltaic panel by the movable channel steel 8, the rollers 9 on the three sides of the movable channel steel 8 can be connected to the photovoltaic panel or the mounting frame on the photovoltaic panel, making it convenient for the movable channel steel 8 to move on the top of the photovoltaic panel.

[0040] In this embodiment, the cleaning vehicle 1 includes an electric crawler transport vehicle and a cleaning roller installed at the front end of the crawler transport vehicle. The electric crawler transport vehicle is equipped with a motor for driving the cleaning roller to rotate and clean.

[0041] Working principle: when the photovoltaic panel needs to be cleaned, the staff first installs the pendant on the top of the photovoltaic panel, and then places the cleaning vehicle 1 on the surface of the photovoltaic panel on one side of the pendant, passes the wire rope 4 around the guide wheel 7 to connect the cleaning vehicle 1 and the pendant, and cleans the photovoltaic panel by operating the cleaning vehicle 1. When the cleaning vehicle 1 moves, it will drive the pendant to move horizontally on the top of the photovoltaic panel to prevent the cleaning vehicle 1 from sliding along the inclined photovoltaic panel. When the cleaning vehicle 1 completes horizontal cleaning and needs to descend to continue cleaning, the staff operates the retractable motor 5 to drive the retractable reel 6 to loosen the wire rope 4, and at the same time the vehicle body moves downward to prepare for cleaning again, and so on, until the surface of the photovoltaic panel is cleaned; when cleaning large-area photovoltaic panels, the staff can install multiple sets of pendants and cleaning vehicles 1 on different photovoltaic panels for unified cleaning and unified change of cleaning positions.

[0042] In combination with the above, the present application stabilizes the cleaning vehicle 1 on the surface of the photovoltaic panel through the setting of the hanger and the distance adjustment device, thereby preventing the cleaning vehicle 1 from sliding along the inclined photovoltaic panel during the cleaning process, improving the cleaning efficiency and cleaning effect, and effectively solving the problem of sliding displacement of the current photovoltaic panel cleaning equipment during the cleaning process.

[0043] Example 2

[0044] like Figures 1-4 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. In this embodiment, in order to facilitate the steel wire rope 4 to remain in a tightened state during the retraction process and the steering process of the cleaning vehicle 1, the retracting and discharging motor 5 is rotatably connected to the movable channel steel 8 in the pendant.

[0045] In this embodiment, in order to prevent the cleaning vehicle 1 and the pendant from falling off the photovoltaic panel when moving left and right, the pendant further includes a positioning switch 10 and a positioning plate 11. The number of the positioning switches 10 and the positioning plates 11 are both two. The two positioning switches 10 are respectively mounted at both ends of the movable channel steel 8, and the two positioning plates 11 are detachably connected to both sides of the photovoltaic panel corresponding to the two ends of the movable channel steel 8.

[0046] The cleaning vehicle 1 is equipped with a controller 14 for controlling the movement of the cleaning vehicle 1. The controller 14 is connected to the positioning switch 10 by signal. In this embodiment, the positioning switch 10 includes a micro switch. The length of the movable channel steel 8 is greater than or equal to the side length of the cleaning vehicle 1. When the cleaning vehicle 1 drives the movable channel steel 8 to move to the side of the photovoltaic panel through the wire rope 4, the positioning switch 10 at the end of the movable channel steel 8 contacts the positioning plate 11 and transmits the signal to the controller 14. The controller 14 controls the cleaning vehicle 1 to stop moving and move down or turn according to the requirements of the staff.

[0047] Example 3

[0048] like Figures 1-4 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, in order to make the hanger and the cleaning vehicle 1 move synchronously, and at the same time make the retraction and extension of the wire rope 4 match the movement of the cleaning vehicle 1, and prevent the wire rope 4 from being loosened or overtightened, a power supply 12 is installed on the cleaning vehicle 1, a conductive slip ring 13 electrically connected to the power supply 12 is installed on the positioning shaft 3, and the retracting and discharging motor 5 is electrically connected to the conductive slip ring 13;

[0049] A drive motor 15 is installed on the movable channel steel 8, the drive motor 15 is electrically connected to the power supply 12, and the drive motor 15 is transmission-connected to one of the rollers 9;

[0050] In order to facilitate stable transmission between the power supply 12, the retractable discharge motor 5, and the drive motor 15 and avoid being affected by changes in the distance between the cleaning vehicle 1 and the hanger, a spring rewinding reel 17 is installed on the movable channel steel 8. The spring rewinding reel 17 is wound with a cable 16. One end of the cable 16 is electrically connected to the conductive slip ring 13, and the other end of the cable 16 is electrically connected to the retractable discharge motor 5 and the drive motor 15. The cable 16 is stored by the spring rewinding reel 17. When the distance between the cleaning vehicle 1 and the hanger changes, the spring rewinding reel 17 can retract and release the cable 16 accordingly without affecting the transmission between the power supply 12, the retractable discharge motor 5, and the drive motor 15. In this embodiment, the retractable discharge motor 5, the drive motor 15, the cleaning vehicle 1, and the positioning switch 10 are all connected to the controller 14 for signal connection, facilitating integrated control; the controller 14 is connected to the power supply 12 for signal connection.
