Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel cleaning devices, specifically to a photovoltaic panel cleaning device and its steering locking structure. Background Technology

[0002] With the vigorous development of clean energy, various clean energy sources are gradually entering the public eye. Among them, photovoltaic power generation, one of the most important energy sources, is becoming increasingly widespread. As the photovoltaic industry continues to develop, many people are beginning to pay attention to and adopt photovoltaic power generation systems. Photovoltaic panels can now be seen on rooftops, in deserts, on hillsides, in rural farmland, and in fishponds.

[0003] In recent years, photovoltaic solar panels have been widely used and their numbers are increasing due to their advantages such as being clean and renewable. However, as their scale continues to expand, a series of related problems have gradually emerged, among which the cleanliness of photovoltaic panel arrays is particularly noteworthy. The large accumulation of dust and dirt on the surface of photovoltaic panels can significantly reduce their power generation efficiency.

[0004] To effectively address this issue, various photovoltaic panel cleaning robots have emerged and their numbers are gradually increasing in the market. However, these existing photovoltaic panel cleaning devices still exhibit some shortcomings that urgently need to be addressed, as follows:

[0005] 1. Poor compatibility with tilt angles. When the photovoltaic panels are at a large tilt angle, the robot often cannot complete the cleaning task smoothly, which greatly limits its application range.

[0006] 2. Poor cleaning stability: During actual cleaning of photovoltaic panels, the existing cleaning robot is prone to slippage when the trolley makes overall turning and changing positions due to the lack of an effective anti-slip and stable support mechanism, which seriously interferes with the normal progress of the cleaning work.

[0007] 3. Difficulty in Cross-Panel Turning: When the robot performs cross-panel turning maneuvers, the brushes are prone to colliding with or obstructing the edges of the photovoltaic panels or adjacent panels, making the overall turning process less smooth and fraught with difficulties. This problem not only significantly affects the cleaning effect but may also cause some degree of damage to the surface of the photovoltaic panels. In addition, this turning obstacle may indirectly cause the robot to wobble or become unstable during the turning process, further reducing the stability and efficiency of the cleaning work.

[0026] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 4As shown, this utility model embodiment provides a steering locking structure for a photovoltaic panel cleaning device, including a main shaft 1, which is rotatably connected to a lower plate 2 of the main body. The main shaft 1 is arranged through the lower plate 2 of the main body. Specifically, a lower bearing seat 7 is fixed on the upper side of the lower plate 2 of the main body, and the main shaft 1 is bearing connected in the bearing seat 7. The lower end of the main shaft 1 is used to install a dual-track walking mechanism 4. A locking sleeve 3 is fixed on the outer side of the main shaft 1 located above the lower plate 2 of the main body. Alternatively, the locking sleeve 3 can be integrally formed with the main shaft 1, and several locking grooves are provided on the outer side of the locking sleeve 3. A telescopic control component 5 is fixed on the lower plate 2 of the main body on one side of the main shaft 1. The telescopic control component 5 is preferably an electric push rod, and the telescopic control component 5 and the locking sleeve 3 are spaced apart. The front end of the telescopic control component 5 is fixedly connected to the spring locking pin assembly 6. The front end of the spring locking pin assembly 6 is adapted to the locking groove. When the telescopic control component 5 extends forward, and the front end of the spring locking pin assembly 6 is aligned with the locking groove, the front end of the spring locking pin assembly 6 can be inserted into the locking groove to achieve steering locking. When the telescopic control component 5 retracts backward, the front end of the spring locking pin assembly 6 can be pulled out of the locking groove to release the lock. Preferably, there are two locking grooves spaced apart at 90° intervals, which can achieve position locking in two 90° interval directions.

[0028] The spring locking pin assembly 6 of this embodiment includes a housing 61, a stop block 62, a spring 63, and a locking pin 64. The housing 61 is fixed to the front end of the telescopic control component 5. Specifically, a threaded groove can be provided at the front end of the telescopic control component 5, and an external thread structure can be provided on the outer side of the rear end of the housing 61, thereby threading the rear end of the housing 61 into the threaded groove. A through hole 65 is provided in the middle of the housing 61. The stop block 62 can be threadedly fixed to the inner side of the rear end of the housing 61. Adjusting the position of the stop block 62 at the rear end of the housing 61 can adjust the elastic force of the spring 63 acting on the positioning pin 64. The locking pin 64 is slidably connected within the through hole 65, with its front end extending outward from the outer side of the housing 61 through the through hole 65. Limiting protrusions 66 are provided at both the rear end of the locking pin 64 and the front end of the housing 61 to prevent the locking pin 64 from sliding out of the through hole 65. Spring 63 is positioned between the rear end of locking pin 64 and stop block 62. Spring 63 is in a compressed state, applying a certain pressure to locking pin 64 forward.

[0029] To improve locking stability, two locking blocks 8 are spaced apart on the upper side of the lower bearing seat 7. A locking rod 9 that cooperates with the locking blocks 8 is fixed on the outside of the locking sleeve 3. The position angle between the locking rod 9 and the two locking blocks 8, and the position angle between the locking pin 64 and the locking groove are adapted. When the locking rod 9 rotates with the locking sleeve 3 and the main shaft 1 to the position of the locking block 8, the locking block 8 and the locking rod 9 cooperate to prevent the main shaft 1 from rotating further, realizing the mechanical locking function. At this time, the locking pin 64 is aligned with one of the locking grooves, so that the locking pin 64 can be inserted into the locking groove. Furthermore, a guide sleeve 10 is fixed on the lower bearing seat 7. The guide sleeve 10 is provided with a guide hole, and the outer side of the housing 61 is slidably connected in the guide hole.

[0030] A main body upper plate 11 is fixedly fixed at intervals on the upper side of the main body lower plate 2. Multiple support columns 12 are provided between the main body upper plate 11 and the main body lower plate 2. The upper and lower ends of the support columns 12 can be bolted to the main body upper plate 11 and the main body lower plate 2 respectively, thereby fixing the main body upper plate 11 to the main body lower plate 2 at intervals. An upper bearing seat 13 is fixed on the lower side of the main body upper plate 11, and the upper bearing seat 13 is connected to the main shaft 1 bearing.

[0031] To facilitate the acquisition of the rotation angle of the spindle 1, the upper end of the spindle 1 is fixedly connected to the lower end of the angle sensor 14. The outer side of the angle sensor 14 is fixed to the upper side of the main body plate 11 by a fixing plate 15. Specifically, the angle sensor 14 includes a housing and a rotating shaft rotatably connected inside the housing. The rotating shaft is fixedly connected to the upper end of the spindle 1 and can rotate with the spindle 1. The housing is fixed to the upper side of the main body plate 11 by the fixing plate 15. When the rotating shaft rotates with the spindle 1, it can output a pulse signal, and then realize angle detection based on the pulse signal.

[0032] Based on the above embodiments, those skilled in the art can easily understand that the present invention also provides a photovoltaic panel cleaning device, which includes the steering locking structure of the photovoltaic panel cleaning device described above.

[0033] During operation, before the photovoltaic panel cleaning device needs to turn, the telescopic control component 5 is first controlled to retract backward, causing the housing 61 to move backward and pulling the locking pin 64 out of the locking groove to release the turning lock. Then, the two tracks of the dual-track walking mechanism are controlled to move in opposite directions. Since the brushes 16 on both sides of the photovoltaic panel cleaning device are in contact with the photovoltaic panel and have a certain friction, the lower plate 2 of the main body remains stationary, while the two tracks drive the dual-track walking mechanism 4 to rotate independently. During this period, the angle sensor 14 collects the rotation angle signal. When the main shaft 1 rotates to the set angle threshold (such as 10°), the telescopic control component 5 can be controlled to extend forward, causing the housing 61 to move forward and the locking pin 64 to press against the outside of the locking sleeve 3 under the action of the spring 63. Since the elasticity of the spring 63 is limited, it will not affect the continued rotation of the main shaft 1. When the main shaft 1 rotates to the preset angle (90°), the locking rod 9 abuts against the corresponding locking block 8, and at the same time the locking pin 64 automatically springs into the locking groove, thereby locking the dual tracked walking mechanism 4 onto the lower plate 2 of the main body. At this time, the dual tracked walking mechanism 4 can be controlled to move in a direction perpendicular to the original direction.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge. Several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
