Description

Technical Field

[0001] The present invention relates to the field of solar photovoltaic system cleaning technology, in particular to a cleaning rail vehicle platform system synchronized with multiple rows of solar photovoltaic systems. Background Art

[0002] In existing solar photovoltaic systems, in order to improve the photoelectric conversion efficiency, a diurnal system is generally installed for the solar photovoltaic panels so that the solar photovoltaic panels can shift in angle with the movement of the sun, thereby ensuring that they are always in a high light-receiving state. The solar photovoltaic system contains a large number of photovoltaic panels. If these photovoltaic panels are cleaned manually, it is not only inefficient but also unsafe. Therefore, a self-propelled cleaning robot is needed to assist in the cleaning operation.

[0003] Existing photovoltaic systems generally consist of several rows of photovoltaic panels, which work in rows. Each row of photovoltaic panels has its own diurnal system set up separately. Therefore, even if the solar photovoltaic panels are in the same row, their deflection angles may vary within the same period of time, making it difficult for self-propelled cleaning robots to accurately identify and align them, thereby affecting the efficiency of cleaning the photovoltaic system. In view of this, we propose a cleaning rail car platform system that is synchronized with multiple rows of diurnal photovoltaic systems. Summary of the Invention

[0016] 1. The cleaning rail vehicle platform system synchronized with multiple rows of solar photovoltaic systems is equipped with a synchronization component, which cooperates with the guide rails arranged under the photovoltaic panels and parallel to the photovoltaic panels and the multiple groups of contact cylinders arranged under the rotatable platform. As the rail vehicle body approaches the photovoltaic panels, it will gradually adapt to the deflection angle of the rotatable platform installed with the self-propelled cleaning robot, so that the rail vehicle body and the photovoltaic panels can be aligned in the horizontal direction and the angle can be synchronized, so as to ensure that the self-propelled cleaning robot can stably and accurately clean the surface of the photovoltaic panels, thereby improving the cleaning efficiency of the device for photovoltaic panels with different inclination angles.

[0030] In one embodiment of the present invention, a support frame 81 is fixedly mounted on the upper surface of the rail car body 1, and an articulated seat 82 is rotatably mounted on the top side wall of the support frame 81, and a rotatable platform 83 is fixedly mounted on the top of the articulated seat 82.

[0031] For further information, please refer to the attached manual. Figures 1-4The photovoltaic panel 4 and the rail car body 1 are separated, and the rail car body 1 is provided with an external adaptive running track to ensure that the rail car body 1 can operate in several rows of photovoltaic systems and realize the cleaning of the photovoltaic panel 4. At the same time, the sun-chasing system 6 includes a control seat 61, which is fixedly mounted on the top of the cement column 2. The side wall of the control seat 61 is fixedly mounted with a deflection frame 62 through a rotating shaft. The photovoltaic panel 4 is fixedly mounted on the upper surface of the deflection frame 62. The inner wall of the control seat 61 is fixedly mounted with a drive motor, and the output shaft of the drive motor is fixedly connected to the above-mentioned rotating shaft. A photoelectric sensor module and a single-chip microcomputer control module are provided inside the photovoltaic panel 4. The photoelectric sensor module detects the position and light intensity of the sun in real time, and sends the data to the single-chip microcomputer. The single chip control module calculates the current position of the sun and the angle that the solar panel should be adjusted according to the received data, and then sends a control signal to the drive motor to control the rotation of the shaft by starting the drive motor, thereby controlling the photovoltaic panel 4 on the cement column 2 to change the angle with the position of the sun, thereby improving the overall photoelectric conversion efficiency of the photovoltaic panel 4, thereby adjusting the angle of the photovoltaic panel 4. At the same time, a motor fixedly connected to the central axis of the track wheel 5 is provided in the rail car body 1, and a control terminal is provided in the control box 7. The control terminal is connected to the motor, the electric push rod 87 and the self-propelled cleaning robot 85 by telecommunications to control the movement of the rail car body 1 and the start and stop of related equipment, thereby realizing the alignment and cleaning operations of the photovoltaic panel 4.

[0032] At the same time, the support frame 81 is arranged in an H shape, and the number of articulated seats 82 is set in two groups, and the two groups of articulated seats 82 are mirror-imaged on the left and right inner surfaces of the support frame 81 to ensure the stability of the movement of the rotatable platform 83. In addition, the size of the self-propelled cleaning robot 85 is adapted to the top space of the rotatable platform 83, so that the self-propelled cleaning robot 85 can return to the rotatable platform 83 for retraction after the cleaning operation is completed, and then move to the next row of photovoltaic panels 4 with the rotatable platform 83 to continue the cleaning operation. At the same time, a self-propelled structure is provided at the bottom of the self-propelled cleaning robot 85 to drive the self-propelled cleaning robot 85 to move and clean synchronously on the photovoltaic panels 4. Furthermore, the number of calibration mounting plates 86 is set in four groups, and the four groups of calibration mounting plates 86 are evenly distributed on the rotatable The lower surfaces of the left and right sides of the platform 83, at the same time, the calibration mounting plate 86 and the rotatable platform 83 are arranged perpendicular to each other, and the inner wall of the calibration mounting plate 86 is provided with a hole for the installation of the electric push rod 87, so that the electric push rod 87 can be arranged horizontally inside the calibration mounting plate 86. In addition, the interior of the contact cylinder 88 is hollow, and the internal cavity of the contact cylinder 88 is adapted to the movable end of the electric push rod 87, so that the contact cylinder 88 can rotate freely on the outer surface of the movable end of the electric push rod 87 to avoid jamming or excessive friction when the rotatable platform 83 is aligned with the photovoltaic panel 4. Specifically, both ends of the guide rail 89 are arranged in an arc shape to avoid jamming of the contact cylinder 88, thereby facilitating the alignment work between the rotatable platform 83 and the photovoltaic panel 4.

[0033] In addition, please refer to the instructions attached Figure 5-Figure 6 The top side of the support frame 81 is provided with a deceleration assembly 9 that can slow down the inertia of the hinge seat 82 during rotation. The deceleration assembly 9 includes a connecting cylinder 91, which is rotatably mounted on the outer wall of the support frame 81 on the side close to the rail car body 1. The connecting cylinder 91 passes through and is fixedly connected to the hinge seat 82. A fixing block 92 is fixedly mounted on the arc-shaped inner wall of the connecting cylinder 91. A fixing rod 93 is passed through and fixedly mounted on the inner wall of the end of the fixing block 92. A shift block 94 is rotatably connected to the end of the fixing rod 93. A coil spring 95 is sleeved on the arc-shaped outer wall of the fixing rod 93. A mounting column 96 is fixedly mounted on the outer wall of the side of the support frame 81 close to the rail car body 1. A gear sleeve 97 is sleeved on the arc-shaped outer wall of the mounting column 96, and a spiral spring 98 is sleeved on the arc-shaped outer wall of the mounting column 96.

[0034] Specifically, a through hole is provided on the inner wall of the hinge seat 82 near the side of the connecting tube 91, which is adapted to the curved outer wall of the connecting tube 91, so as to facilitate the fixed installation between the connecting tube 91 and the hinge seat 82, so that the hinge seat 82 can rotate on the side wall of the support frame 81 with the connecting tube 91 as the rotation center. At the same time, there are multiple groups of fixing blocks 92, and the multiple groups of fixing blocks 92 are evenly distributed in a circular array on the curved inner surface of the connecting tube 91. Furthermore, a swing groove with a width adapted to the width of the fixing block 92 is provided at the center of the shift block 94, and circular holes with a diameter larger than the outer diameter of the coil spring 95 are provided on the inner walls at both ends of the swing groove, and the two ends of the coil spring 95 are fixedly connected to the bottom inner wall of the circular hole and the curved outer wall of the fixing rod 93 respectively, so that the shift block 94 always has a tendency to rotate in the opposite direction to achieve reset when it rotates with the fixing rod 93 as the rotation center.

[0035] At the same time, the mounting post 96 is arranged at the axis of the connecting cylinder 91, and a cylindrical transmission cavity is opened inside the gear sleeve 97, and a volute spring 98 is arranged in the cylindrical transmission cavity. Specifically, the two ends of the volute spring 98 are fixedly connected to the inner wall of the end of the cylindrical transmission cavity and the arc-shaped outer wall of the mounting post 96, so that when the gear sleeve 97 rotates with the mounting post 96 as the rotation center, it always has a movement tendency of reverse rotation to achieve reset. Therefore, when the rotatable platform 83 is guided and tends to rotate parallel to the photovoltaic panel 4, the articulated seat 82 drives the connecting cylinder 91 to rotate. At this time, through the connecting cylinder The relative rotation of 91 and the gear sleeve 97 causes the shift block 94 to engage with the tooth edges provided on the arc-shaped outer wall of the gear sleeve 97, thereby reducing the rotation speed of the connecting tube 91 and the hinge seat 82. At the same time, the arrangement of the coil spring 95 and the spiral spring 98 prevents the shift block 94 and the gear sleeve 97 from getting stuck. When the impact force is large, the shift block 94 rotates with the fixed rod 93 as the rotation axis and the gear sleeve 97 rotates with the mounting column 96 as the rotation axis to avoid direct collision, thereby making the rotation alignment process of the rotatable platform 83 smoother, ensuring the safety and stability of the device during use.

[0036] In the embodiments of the present invention, please refer to the attached Figure 7-Figure 9, a brake assembly 10 is provided on the top side of the support frame 81 to ensure the relative stability of the rotatable platform 83 during the cleaning operation. The brake assembly 10 includes a transmission column 101, which is rotatably connected to the top side wall of the support frame 81. A brake disc 102 is fixedly installed on the end of the transmission column 101 away from the support frame 81, and a driving seat 103 is fixedly installed on the outer wall of the side of the support frame 81 close to the rail car body 1. A positive electric push rod 104 is fixedly installed on the inner wall of the side of the drive seat 103 away from the support frame 81, and the output end of the positive electric push rod 104 is fixed. It is fixedly connected to an outer brake plate 105, and a counter-electric push rod 106 is fixedly installed on the inner wall of the driving seat 103 away from the support frame 81. The output end of the counter-electric push rod 106 is fixedly connected to an inner brake plate 107, and a rubber belt 108 is provided on the outer wall of the inner brake plate 107. A return spring 1010 is fixedly connected to the inner wall of the inner brake plate 107 away from the driving seat 103, and an end of the return spring 1010 away from the inner brake plate 107 is fixedly connected to an extrusion block 109, and a magnetic sheet 1011 is fixedly installed on the outer wall of the extrusion block 109 away from the inner brake plate 107.

[0037] It is worth noting that the brake assembly 10 is arranged on the side of the support frame 81 away from the deceleration assembly 9. Specifically, the deceleration assembly 9 and the brake assembly 10 are respectively arranged at the top ends of the left and right sides of the support frame 81 arranged in an H shape, so that the rotation of the rotatable platform 83 is more stable. At the same time, the positive electric push rod 104 is arranged below the reverse electric push rod 106, and the positive electric push rod 104 and the reverse electric push rod 106 are both connected to the control terminal in the control box 7 by telecommunication. When the rail car body 1 moves to approach the photovoltaic panel 4, the positive electric push rod 104 is driven to extend outward by the control terminal, and the reverse electric push rod 106 is controlled to retract inward, so that the outer brake plate 105 and the inner brake plate 107 are separated from the contact with the brake disc 102, thereby releasing the brake. The transmission column 101, the brake disc 102 and the articulated seat 82 are placed to prompt the articulated seat 82 to drive the rotatable platform 83 to rotate. After completing the alignment and calibration, the positive electric push rod 104 is driven inward by the control terminal, and the negative electric push rod 106 is controlled to extend outward, so that the outer brake plate 105 and the inner brake plate 107 are both close to the brake disc 102, and finally the brake disc 102 is clamped to limit the displacement of the brake disc 102 and the transmission column 101, so that the articulated seat 82 and the rotatable platform 83 no longer rotate. At this time, the rotatable platform 83 is aligned with the upper surface of the photovoltaic panel 4, and the electric push rod 87 is started again to cooperate with the self-propelled cleaning robot 85 to clean the surface of the photovoltaic panel 4.

[0038] In addition, a contraction groove smaller than the size of the extrusion block 109 is opened inside the inner brake plate 107, and the inner brake plate 107 is made of a rubber block on the side close to the brake disc 102, so that the extrusion block 109 will fill and expand the contraction groove when moving toward the contraction groove, so as to make the protrusion of the inner brake plate 107 fit the brake disc 102 more closely, thereby improving the locking effect of the inner brake plate 107 on the brake disc 102. Specifically, the outer brake plate 105 is arranged in the same manner on the side close to the inner brake plate 107, and another set of extrusion blocks are provided on the side close to the inner brake plate 107 of the outer brake plate 105. The pressure block 109 and the magnetic sheet 1011, and the magnetic properties of the magnetic sheets 1011 corresponding to the inner brake plate 107 and the outer brake plate 105 are opposite, so that the two magnetic sheets 1011 have attraction when they are close to each other, thereby promoting the inner brake plate 107 and the outer brake plate 105 to have a better adhesion effect when clamping the brake disc 102, and cooperating with the extrusion block 109 to squeeze and expand the shrinkage groove, so that the rubber belt 108 fits more closely to the outer surface of the brake disc 102, ensuring its stability during positioning, and then ensuring the stability of the rotatable platform 83 during the cleaning operation of the photovoltaic panel 4.

[0039] In the present invention, when in use, a command is issued by the control terminal in the control box 7 provided on the rail car body 1 to drive the motor provided in the rail car body 1 to start, so that it drives the track wheel 5 to rotate, so that the rail car body 1 slides on the pre-laid track to approach the photovoltaic panel 4 in the horizontal direction. In the process of the rail car body 1 approaching the photovoltaic panel 4, the electric push rod 87 is started by the control terminal, so that the electric push rod 87 pushes the contact cylinder 88 and extends it toward the side of the photovoltaic panel 4. At this time, as the rail car body 1 continues to move, the contact cylinder 88 first contacts the lower surface of the guide rail 89, and in the process of the rail car body 1 continuing to approach the photovoltaic panel 4, the multiple groups of contact cylinders 88 provided on the lower surface of the rotatable platform 83 are successively pressed against the guide rail 89. Until all the contact cylinders 88 are fully pressed against the guide rail 89, the control terminal sends a stop command to the motor in the rail car body 1, so that the track wheel 5 stops rotating. At this time, the rail car body 1 and the photovoltaic panel 4 are relatively stationary, and the rotatable platform 83 also maintains a flush state with the photovoltaic panel 4.

[0040] Afterwards, the control terminal drives the positive electric push rod 104 to extend outward, and controls the reverse electric push rod 106 to retract inward, so that the outer brake plate 105 and the inner brake plate 107 are out of contact with the brake disc 102, thereby releasing the transmission column 101 and the brake disc 102 and the articulated seat 82, so that the articulated seat 82 drives the rotatable platform 83 to rotate. After completing the alignment calibration, the control terminal drives the positive electric push rod 104 to retract inward, and controls the reverse electric push rod 106 to extend outward, so that the outer brake plate 105 and the inner brake plate 107 are both close to the brake disc 102, and finally the brake disc 102 is clamped to limit the displacement of the brake disc 102 and the transmission column 101, thereby making the articulated seat 82 and the rotatable platform 83 no longer rotate. Then, the control terminal sends an instruction to the self-propelled cleaning robot 85, so that the self-propelled cleaning robot 85 cleans the surface of the photovoltaic panel 4 on the side under the drive of its internal self-propelled structure.

[0041] After the cleaning operation is completed, the control terminal sends an instruction to the self-propelled cleaning robot 85, causing the self-propelled cleaning robot 85 to execute the retraction instruction. The self-propelled cleaning robot 85 moves along the surface of the photovoltaic panel 4 toward the upper surface of the rotatable platform 83, and at the same time, the electric push rod 87 is retracted, and finally the contact cylinder 88 is disengaged from the guide rail 89. After the above steps are completed, the control terminal sends an instruction to the motor to drive the track wheel 5 to rotate, driving the track car body 1 to move to the next row of photovoltaic panels 4, thereby completing the cleaning work of the next row of photovoltaic panels 4.

[0042] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
