Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power stations, in particular to a limiting device, a ferry vehicle, a photovoltaic cleaning system and a photovoltaic power station. Background Art

[0002] The shuttle bus is an auxiliary device for the photovoltaic module cleaning robot. It transforms the traditional cleaning mode of a single row of photovoltaic modules equipped with a separate cleaning robot into a mode in which multiple rows of photovoltaic modules are cleaned by a cleaning robot in cooperation with a shuttle bus. After cleaning a row of photovoltaic modules, the cleaning robot moves directly to the shuttle bus connected to the row of photovoltaic modules. This mode realizes the cleaning of multiple rows of photovoltaic modules, thereby improving the utilization rate of the cleaning robot.

[0003] At present, a limiting device is usually fixed on one side of the shuttle bus, so that the cleaning robot is limited to this side, and there is no obstruction on the other side of the shuttle bus, so that the cleaning robot can get on and off the shuttle bus. Although the setting of the limiting device has achieved the limit of the cleaning robot on the shuttle bus, it occupies one side of the shuttle bus, so that the cleaning robot can only get on and off along one side of the shuttle bus. In other words, the shuttle bus can only be used in a single-side cross-row scenario. If you want to clean the photovoltaic panels on both sides of the shuttle bus, you need to build two sets of ferry systems and related tracks. On the one hand, this greatly increases the project cost and construction period. On the other hand, it also occupies more space. When the middle channel between adjacent photovoltaic panels is narrow, it cannot be arranged, resulting in greatly reduced adaptability. Utility Model Content

DETAILED DESCRIPTION

[0060] The following will be combined with the attached embodiment of the present utility model Figure 1-5 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel efforts are within the scope of protection of the utility model.

[0061] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0062] Combination Figure 1-Figure 5 As shown, the first aspect of the utility model provides a limiting device 100 for limiting the position of a cleaning robot on a shuttle vehicle 1000.

[0063] like Figure 1 As shown, the limiting device 100 includes a movable limiting structure 101, and the movable limiting structure 101 is retractably mounted on the load-bearing portion 200 of the shuttle bus 1000. It should be noted that the retractability here can be achieved by the movable limiting structure 101 moving itself to extend to the outside of the load-bearing portion 200 or shrinking to the inside of the load-bearing portion 200, or by the movable limiting structure 101 material deforming itself to extend to the outside of the load-bearing portion 200 or shrinking to the inside of the load-bearing portion 200, or by the movable limiting structure 101 moving itself in combination with the movable limiting structure 101 material deforming itself to extend to the outside of the load-bearing portion 200 or shrinking to the inside of the load-bearing portion 200.

[0064] When the movable limiting structure 101 extends out of the carrying part 200, the movable limiting structure 101 limits the cleaning robot carried on the carrying part 200; when the movable limiting structure 101 retracts into the carrying part 200, the movable limiting structure 101 releases the limit on the cleaning robot, so that the cleaning robot can move to either side of the shuttle bus 1000.

[0065] It should be noted that the movable limiting structure 101 limiting the position of the cleaning robot means that the movable limiting structure 101 at least limits the movement of the cleaning robot from one side to the other side of the shuttle bus 1000. The two sides of the shuttle bus 1000 refer to the two sides of the shuttle bus 1000 arranged along the vertical walking direction (i.e., the width direction of the carrying part 200).

[0066] like Figure 1 As shown, the bearing part 200 is a rectangular frame structure arranged obliquely, and the guide wheels of the cleaning robot slide along the side wall of the bearing part 200. The cleaning robot is provided with at least two guide wheels at the side walls of the bearing part 200 at both ends along the length direction of the bearing part 200. The setting of the guide wheels at both ends of the length direction of the bearing part 200 of the cleaning robot limits the movement of the cleaning robot along the length direction of the bearing part 200. The movable limiting structure 101 is limited between the two guide wheels to limit the movement of the cleaning robot along the width direction of the bearing part 200. The running wheels arranged on the cleaning robot are perpendicular to the guide wheels, and the running wheels are used for the cleaning robot to slide along the top surface of the bearing part 200.

[0067] like Figure 2 As shown, the width direction of the carrying portion 200 is taken as the X direction and the length direction is taken as the Y direction as an example.

[0068] The utility model realizes the limiting and contact limiting of the cleaning robot by the retractable movable limiting structure 101 relative to the bearing part 200, so that the cleaning robot can get on and off the shuttle bus 1000 along any side of the shuttle bus 1000, thereby realizing the cleaning of photovoltaic modules on both sides of the shuttle bus 1000, and improving the applicability of the shuttle bus 1000.

[0069] In the limiting device 100 provided in an embodiment of the present utility model, the movable limiting structure 101 includes a direct push limiting block 101-1 and a driving member 101-2, and the direct push limiting block 101-1 can be slidably installed in the bearing part 200. Specifically, a slide rail can be provided on one of the inner cavity wall of the bearing part 200 and the direct push limiting block 101-1, and a slide groove slidably connected to the slide rail can be provided on the other; the shape of the direct push limiting block 101-1 can also be adapted to the shape of the inner cavity of the bearing part 200, so that the direct push limiting block 101-1 can directly slide with the inner cavity of the bearing part 200, etc.

[0070] The driving member 101-2 is mounted on the bearing portion 200 and connected to one end of the direct push limit block 101-1. Specifically, the driving member 101-2 is mounted on the bearing portion 200 through the driving bracket 101-3, that is, the driving member 101-2 is mounted on the driving bracket 101-3, and the driving bracket 101-3 is mounted on the bearing portion 200. In order to facilitate the disassembly and assembly of the driving member 101-2 and the disassembly and assembly of the driving bracket 101-3, in this embodiment, the driving member 101-2 is detachably mounted on the driving bracket 101-3 through a fastener, and the driving bracket 101-3 is detachably mounted on the bearing portion 200 through a fastener. When the driving member 101-2 needs to be disassembled and assembled, only the driving bracket 101-3 needs to be disassembled and assembled, thereby avoiding multiple direct disassembly and assembly of the driving member 101-2, which may cause damage to the driving member 101-2.

[0071] It can be understood that the connection between the driving member 101-2 and one end of the direct push limit block 101-1 means that the driving end of the driving member 101-2 is connected to one end of the direct push limit block 101-1. The driving member 101-2 can be a cylinder, a hydraulic cylinder, or an electric push rod or a gear rack structure.

[0072] The driving member 101-2 is used to drive the direct push limit block 101-1 to extend outside the bearing part 200 to limit the cleaning robot, or to retract into the bearing part 200 to release the limit on the cleaning robot. The driving member 101-2 drives the direct push limit block 101-1 to extend and retract, thereby avoiding manual adjustment of the direct push limit block 101-1 and saving manpower.

[0073] In the limiting device 100 provided in one embodiment of the present invention, the number of movable limiting structures 101 is at least one, and the movable limiting structure 101 is installed at least at one end of the carrying part 200 , that is, at least one end of the cleaning robot along the width direction of the carrying part 200 is limited.

[0074] In order to improve the limiting stability of the cleaning robot, at least one movable limiting structure 101 can be provided at both ends of the length direction of the bearing part 200. In order to reduce the number of required driving members 101-2, the movable limiting structure 101 at one end of the length direction of the bearing part 200 can be replaced by other structures, such as Figure 2As shown, in the limiting device 100 provided in one embodiment of the utility model, the limiting device 100 also includes an indirect limiting structure 102, a movable limiting structure 101 can be telescopically installed at one end of the bearing part 200, and the indirect limiting structure 102 can be telescopically installed at the other end of the bearing part 200. The indirect limiting structure 102 is transmission-connected with the movable limiting structure 101, and the indirect limiting structure 102 is driven to enter and exit the bearing part 200 by the movable limiting structure 101, thereby realizing the release of the limiting or limiting cleaning robot. That is, in this embodiment, the power of the indirect limiting structure 102 is provided by the movable limiting structure 101, and there is no need to set the driving member 101-2, which reduces the cost.

[0075] In the limiting device 100 provided in an embodiment of the utility model, the indirect limiting structure 102 includes an indirect limiting block 102-1 and a push rod 102-2, and the indirect limiting block 102-1 can be slidably installed on the bearing part 200. Specifically, a slide rail can be provided on one of the inner cavity wall of the bearing part 200 and the indirect limiting block 102-1, and a slide groove slidably connected to the slide rail can be provided on the other; the shape of the indirect limiting block 102-1 can also be adapted to the shape of the inner cavity of the bearing part 200, so that the indirect limiting block 102-1 can directly slide with the inner cavity of the bearing part 200, etc.

[0076] One end of the push rod 102-2 is connected to the indirect limit block 102-1. Specifically, the push rod 102-2 can be welded to the indirect limit block 102-1, or can be detachably connected by fasteners. The other end of the push rod 102-2 is transmission-connected to the movable limit structure 101. Specifically, the push rod 102-2 is transmission-connected to the driving member 101-2 of the movable limit structure 101. When the length of the bearing portion 200 is small, the driving member 101-2 can be set as a double-acting cylinder, one cylinder rod of the double-acting cylinder is connected to the push rod 102-2, and the other cylinder rod is connected to the direct push limit block 101-1. That is, the telescopic movement of the indirect limit block 102-1 and the direct push limit block 101-1 is realized by one driving member 101-2, which reduces the cost.

[0077] It can be understood that the above-disclosed one driving member 101-2 directly driving the indirect limit block 102-1 and the direct push limit block 101-1 to extend and retract is only a specific implementation of the present utility model. In actual applications, a transmission assembly 103 can also be set to transmit the power of the driving member 101-2 to the indirect limit block 102-1.

[0078] like Figure 3 As shown, in the limiting device 100 provided in one embodiment of the utility model, the limiting device 100 further includes a transmission assembly 103, and the push rod 102-2 is connected to the movable limiting structure 101 through the transmission assembly 103, thereby realizing power transmission.

[0079] An elastic reset member 102-3 is installed in the bearing part 200, and the elastic reset member 102-3 drives the indirect limit block 102-1 to extend out of the bearing part 200. The transmission assembly 103 includes a direct push pulley assembly 103-1, a transmission rope 103-3 and a steering wheel assembly 103-2, and the direct push pulley assembly 103-1 is installed on the movable limit structure 101. Specifically, the direct push pulley assembly 103-1 includes a direct push pulley fixing frame 103-1-1 and a direct push pulley 103-1-2, wherein the direct push pulley fixing frame 103-1-1 is detachably installed on the direct push limit block 101-1 by fasteners such as screws, and the direct push pulley 103-1-2 is installed on the direct push pulley fixing frame 103-1-1. One end of the transmission cable 103-3 is fixed on the movable limit structure 101. Specifically, a connecting frame 103-4 is installed on the direct push limit block 101-1, and the transmission cable is hinged on the connecting frame 103-4. The transmission cable 103-3 is wound around the direct push pulley assembly 103-1, and the other end is respectively wound around the direct push pulley assembly 103-1 and the steering wheel assembly 103-2, and is connected to the push rod 102-2, and is used to pull the push rod 102-2, thereby driving the indirect limit block 102-1 to retract into the bearing part 200. The power of the driving member 101-2 is transmitted to the indirect limit block 102-1 through the transmission cable 103-3, which reduces the number of required driving members 101-2 and facilitates the control of the driving member 101-2.

[0080] The steering wheel assembly 103-2 is installed on the bearing part 200. Specifically, the steering wheel assembly 103-2 includes a first steering wheel 103-2-1, a second steering wheel 103-2-2 and a steering fixing plate 103-2-3, wherein the steering fixing plate 103-2-3 is installed on the bearing part 200, the first steering wheel 103-2-1 is fixed on the steering fixing plate 103-2-3, and is arranged at the same height as the straight push pulley 103-1-2, so as to facilitate the movement of the transmission cable 103-3. The outgoing end of the transmission cable 103-3 bypassing the second steering wheel 103-2-2 is connected to the push rod 102-2, and the outgoing end of the transmission cable 103-3 bypassing the second steering wheel 103-2-2 is at the same height as the push rod 102-2, so as to facilitate the transmission cable 103-3 to pull the push rod 102-2.

[0081] In order to facilitate the guidance of the push rod 102-2 and the installation of the elastic reset member 102-3, in the limiting device 100 provided in an embodiment of the utility model, a push rod limiting plate 102-4 is provided in the bearing part 200, and a guide hole is provided on the push rod limiting plate 102-4 to be slidably connected to the push rod 102-2. The elastic reset member 102-3 is sleeved outside the push rod 102-2, and one end is abutted or connected to the indirect limiting block 102-1, and the other end is abutted or connected to the push rod limiting plate 102-4. Specifically, the elastic return member 102-3 is a spring in a compressed state. The setting of the elastic return member 102-3 drives the indirect limit block 102-1 to be in a state of extending out of the bearing part 200. The driving member 101-2 is only required to drive the indirect limit block 102-1 to retract into the bearing part 200, and the driving member 101-2 is not required to drive the indirect limit block 102-1 to extend out of the bearing part 200, thereby reducing the power required by the driving member 101-2 and saving energy.

[0082] It can be understood that the installation position of the elastic return member 102-3 disclosed above is only a specific embodiment of the present utility model. In actual applications, it can also be set to other positions. For example, the push rod limit plate 102-4 is not set, and an abutment plate is set at the end of the push rod 102-2 away from the indirect limit block 102-1, so that the abutment plate abuts against one end of the elastic return member 102-3, the elastic return member 102-3 is in a compressed state, and the other end is connected to the limit plate in the bearing part 200. The elastic return member 102-3 pushes the abutment plate, thereby realizing that the indirect limit block extends outside the bearing part 200.

[0083] In the limiting device 100 provided in one embodiment of the utility model, the limiting device 100 further includes a sensing structure 104, which is telescopically mounted on the movable limiting structure 101 or the indirect limiting structure 102. When the movable limiting structure 101 or the indirect limiting structure 102 extends out of the bearing portion 200, the sensing structure 104 extends to the movable limiting structure 101 or the indirect limiting structure 102, so that the cleaning robot can detect the sensing structure 104; when the movable limiting structure 101 or the indirect limiting structure 102 shrinks to the bearing portion 200, the sensing structure 104 shrinks into the movable limiting structure 101 or the indirect limiting structure 102. The setting of the sensing structure 104 facilitates the cleaning robot to sense the state of the movable limiting structure 101 or the indirect limiting structure 102, thereby facilitating the start and stop of the cleaning robot.

[0084] In the limiting device 100 provided in one embodiment of the utility model, the sensing structure 104 includes a telescopic sensing block 104-1 and an elastic telescopic member 104-2. The telescopic sensing block 104-1 can be slidably installed in the movable limiting structure 101 or the indirect limiting structure 102, and the elastic telescopic member 104-2 is installed in the movable limiting structure 101 or the indirect limiting structure 102, and one end is connected or abutted with the telescopic sensing block 104-1, so that the telescopic sensing block 104-1 extends to the outside of the movable limiting structure 101 or the indirect limiting structure 102. Specifically, the telescopic sensing block 104-1 can be slidably installed in the direct push limiting block 101-1 or the indirect limiting block 102-1.

[0085] The telescopic sensing block 104-1 is provided with an inclined pushing surface. When the movable limiting structure 101 or the indirect limiting structure 102 is retracted into the bearing part 200, the inclined pushing surface abuts against one end of the bearing part 200, so that the telescopic sensing block 104-1 compresses the elastic telescopic member 104-2 into the movable limiting structure 101 or the indirect limiting structure 102. The telescopic sensing block 104-1 is automatically extended and retracted by the interaction between the telescopic sensing block 104-1, the elastic telescopic member 104-2 and the bearing part 200, without the need to provide a power part such as a cylinder to drive the telescopic sensing block 104-1 to extend and retract, thereby reducing the cost.
