[0002] As an important clean energy, solar energy has gradually been paid attention to in recent years, and converting solar energy into electric energy by using solar panels is a very important means of utilizing solar energy. With the passage of time, more and more solar power stations based on solar panels have been built. However, the power generation performance of solar panels is easily affected by external factors, and when the surface of a solar panel is covered with dust and other sundries, the power generation efficiency of the solar panel will be greatly reduced. If manual dust cleaning is used, a large amount of time and manpower will be wasted for a solar power station using large-scale solar panels.

DETAILED DESCRIPTION

[0028] The following is a specific embodiment of the present application and further describes the technical solution of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0029] A kind of mobile platform applied to solar panel cleaning, including: slide rail 1, bearing platform 2, interface track 3, power device 4.Slide rail 1 is arranged in the side of solar cell panel array, and the connecting block 11 for being connected with interface track 3 is arranged on slide rail 1.Interface track 3 is arranged between slide rail 1 and solar cell panel array, and the number of interface track 3 is multiple, and interface track 3 corresponds to solar cell panel array.Wherein, one interface track 3 at least includes three sub tracks 31, wherein two sub tracks 31 correspond to the end of solar cell panel array respectively, and another sub track 31 corresponds to the middle of solar cell panel array.One end of sub track 31 is fixedly connected by connecting block 11, and sub track 31 can be kept flat with the upper plane of bearing platform 2 by connecting block 11.Bearing platform 2 includes bearing rod 21, reinforcing rod 22, interface rod 23.The number of bearing rod 21 is two, and bearing rod 21 is arranged in parallel between bearing rod 21, and bearing rod 21 is slidably arranged on slide rail 1 by pulley 211 on bearing rod 21.Limiting wheel 212 is also arranged on bearing rod 21, and slide groove 12 corresponding to limiting wheel 212 is arranged on slide rail 1, and limiting wheel 212 is slidably embedded in slide groove 12.Wherein, pulley 211 and limiting wheel 212 are respectively placed on two mutually perpendicular planes on slide rail 1.By limiting wheel 212, on the one hand, the sliding range of bearing platform 2 can be limited, and on the other hand, bearing platform 2 can be effectively prevented from tilting under the influence of wind or other external forces.Reinforcing rod 22 is arranged between bearing rod 21, and the two ends of reinforcing rod 22 are fixedly connected with bearing rod 21 to strengthen the structural strength of bearing platform 2 itself.Interface rod 23 is connected with bearing rod 21, and interface rod 23 protrudes from one side of bearing rod 21, and the number of interface rod 23 is at least three, and interface rod 23 corresponds to sub track 31 one by one, when bearing platform 2 moves to interface track 3, interface rod 23 can correspond to sub track 31, at this time, interface rod 23 and sub track 31 are located on the same straight line.If the solar cell panel array to be cleaned is arranged in an inclined state, then the number of power device 4 is one, and power device 4 is arranged at one end of slide rail 1, when bearing platform 2 moves from the higher end of slide rail 1 to the lower end, power device 4 is released to make bearing platform 2 slide along slide rail 1 under the action of gravity, when bearing platform 2 moves from the lower end of slide rail 1 to the higher end, power device 4 pulls bearing platform 2 to slide.If the solar cell panel array to be cleaned is arranged in a horizontal state, then the number of power device 4 is two, and power device 4 is arranged at both ends of slide rail 1 to drive bearing platform 2 to move in two different directions, so that bearing platform 2 can move from one end of slide rail 1 to the other end.

[0030] In actual operation, the number of the docking tracks 3 can be two or more, and two docking tracks 3 are taken as an example, that is, there are six sub-tracks 31 to correspond to two rows of solar panel arrays respectively. The cleaning robot is placed on the bearing platform 2, and the wheels of the cleaning robot are in contact with the bearing rods 21. The cleaning robot can adopt the form described in the patent document with the application number CN201822020674.4, or other forms similar thereto. When the cleaning robot operates, it will move along the docking rod 23, and finally move to the solar panel array through the docking track 3. When the cleaning of the solar panel array is completed, the cleaning robot will move in the opposite direction, and finally return to the bearing platform 2 through the docking track 3. At this time, the manually controlled form can be adopted to start the power device 4, so that the bearing platform 2 carrying the cleaning robot moves to the next docking track 3. At this time, the docking rod 23 and the next docking track 3 are docked, and the cleaning robot is started again, so as to complete the cleaning of the next row of solar panel arrays. In this way, a single cleaning robot can clean two rows of solar panel arrays or multiple rows of solar panel arrays, so that it is not necessary to set a corresponding cleaning robot for each row of solar panel arrays, thereby greatly reducing the configuration cost of the solar power station. Specifically, the control mode related to the operation of the cleaning robot can be realized by using the existing technology, which is not the focus of the present application, and therefore will not be described herein.

[0031] The position detection device 13 is arranged on the slide rail 1 to detect whether the cleaning robot moves to the bearing platform 2. The installation position of the position detection device 13 should correspond to the docking rail 3, so that the position detection device 13 can be triggered when the cleaning robot moves to the bearing platform 2. Specifically, the position detection device 13 includes a swing part 131 and a mounting rod 132. The swing part 131 is swingably arranged at one end of the mounting rod 132, and the other end of the mounting rod 132 is fixedly connected with the slide rail 1. A small magnet is arranged on the swing part 131, and a magnetic induction sensor is arranged on the mounting rod 132. An arc-shaped docking interface 1311 is further arranged on the swing part 131. A push rod for pushing the swing part 131 to swing is arranged on the cleaning robot. During the movement of the cleaning robot to the bearing platform 2, the push rod will enter the arc-shaped docking interface 1311, and with the movement of the cleaning robot, the push rod will push the swing part 131 to swing, so that the small magnet moves to the sensing range of the magnetic induction sensor to trigger the magnetic induction sensor. At this time, the magnetic induction sensor outputs a corresponding electrical signal, indicating that the cleaning robot has moved to the bearing platform 2. When the cleaning robot is separated from the bearing platform 2, the push rod will be separated from the arc-shaped docking interface 1311, thereby pushing the swing part 131 to swing in the opposite direction, so that the swing part 131 swings in the opposite direction to the initial position. The swing part 131 further comprises a tension spring, one end of the tension spring is connected with the swing part 131, and the other end of the tension spring is connected with the mounting rod 132. The tension spring continuously applies a pulling force to the swing part 131, so that the swing part 131 is pulled to swing to the position during the swing of the swing part 131, so as to avoid the magnetic induction sensor misjudgment caused by the swing part 131 not swinging to the position.

[0032] The sensing device can also use a light sensor. When the swing part 131 blocks the light sensor, the light sensor outputs a corresponding electrical signal.

[0033] The power device 4 includes a wire rod 41, a power motor 42, and a transmission device 43. The power motor 42 is in transmission connection with the wire rod 41 through the transmission device 43. The wire rod 41 is wound with a steel wire, and the wire rod 41 is connected with the bearing platform 2 through the steel wire.

[0034] For example, when the solar panel array needs to be arranged in an inclined state, the power motor 42 is actuated to rotate the wire rod 41, so that the steel wire is unwound from the wire rod 41, and the bearing platform 2 slides along the slide rail 1 under the action of gravity. When the bearing platform 2 needs to be moved from the lower end of the slide rail 1 to the higher end, the power motor 42 is reversely actuated to reversely rotate the wire rod 41, so that the steel wire is wound on the wire rod 41, and the bearing platform 2 is reversely pulled to slide along the slide rail 1. The wire rod 41 is arranged in an inclined state, that is, an angle is formed between the rotation shaft of the wire rod 41 and the extension direction of the butt joint rail 3. When the steel wire is wound on the wire rod 41, the steel wire is uniformly wound from one end of the wire rod 41 to the other end, so that the steel wire is not wound in a bundle on the wire rod 41, and the normal operation of the power device 4 is effectively avoided.

[0035] The transmission device 43 comprises driving teeth 431 and driven teeth 432. The driving teeth 431 are connected with the power motor 42, and extend along the rotation shaft of the power motor 42. An interval is formed between two adjacent driving teeth 431. The driven teeth 432 are connected with the wire rod 41, and extend along the rotation shaft of the wire rod 41. An interval is formed between two adjacent driven teeth 432. The driven teeth 432 extend into the interval between the driving teeth 431, so that the driving teeth 431 and the driven teeth 432 are engaged with each other. Rubber is arranged between the driving teeth 431 and the driven teeth 432. Thus, the driving teeth 431 and the driven teeth 432 are not rigidly connected, and a certain space is formed between the driving teeth 431 and the driven teeth 432, so that a certain angle is formed between the rotation shaft of the power motor 42 and the rotation shaft of the wire rod 41. On the one hand, the requirement of the inclined arrangement of the wire rod is met, and on the other hand, a certain fault tolerance space is reserved for the rotation of the power motor 42 and the wire rod 41, so that when the power motor 42 and the wire rod 41 are loosened due to the increase of the operation time, the power motor 42 or the wire rod 41 is not seriously damaged. Meanwhile, the installation of the installation personnel is facilitated.

[0036] It is worth noting that the two rows of solar panels described in the specification refer to two rows that are independent of each other. In actual installation, a certain interval is arranged between the two rows of solar power generation devices. The two rows of solar panels are not parallelly arranged on the same solar power generation device.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
