Description

Technical Field

[0001] The present application relates to the field of photovoltaic cleaning technology, and in particular to a photovoltaic power station cleaning robot system. Background Art

[0002] Photovoltaic array is a device that converts solar energy into electrical energy. The power generation efficiency and service life of photovoltaic array are greatly affected by dirt, so it is particularly important to clean the photovoltaic array regularly or on demand. In order to facilitate the cleaning of photovoltaic arrays, the industry has developed cleaning equipment such as photovoltaic cleaning robots.

[0003] In the prior art, there are usually two ways for a photovoltaic cleaning robot to move on a photovoltaic array: one is a trackless method, that is, there is no need to lay out additional tracks for the photovoltaic cleaning robot to walk on, but the photovoltaic cleaning robot walks on the frame of the photovoltaic array; the other is a tracked method, that is, an additional track for the photovoltaic cleaning robot to walk is laid on the outside of the photovoltaic array. The trackless method has a simple structure, but because the frame of the photovoltaic array is relatively smooth, especially when it snows or ices, the photovoltaic cleaning robot will slip; the tracked method requires additional track laying, and the structure and operation are complicated, and the cost is increased; moreover, for photovoltaic power stations set up in small areas such as rooftops and courtyards, the tracked method requires additional space, which makes the layout inconvenient or reduces the area that can be used to arrange the photovoltaic power station. These reasons have led to the lack of the use of cleaning robots in photovoltaic arrays in snowy areas in northern my country, especially rooftop photovoltaic power stations in northern my country, which has seriously affected the power generation efficiency.

[0004] Based on this, it is necessary to propose a new technical solution to overcome the shortcomings of the existing technology. Summary of the invention

In a preferred embodiment, the robot body 4 is fixed to the transmission chain 31.

[0029] The photovoltaic power station cleaning robot system provided in the present application is driven by a drive mechanism 2 to drive a transmission chain 31, so that the transmission chain 31 pulls the robot body 4 to move on the photovoltaic power station 1, without the need for additional track arrangement, and the drive mechanism 2 does not need to follow the operation of the robot body. The weight of the robot body 4 is greatly reduced from the overall design, and thus it is more suitable for operation on small-area photovoltaic power stations 1 such as roofs, and the robot is not prone to slipping during operation, making it more suitable for clearing accumulated snow.

[0030] See also Figures 1 to 4 As shown, the photovoltaic power station 1 includes a plurality of purlins 11 for supporting the photovoltaic panel array, the plurality of purlins 11 extend out of the photovoltaic panel array, the driving mechanism 2 and the transmission mechanism 3 are both installed on the purlins, the robot body 4 also runs on the purlins 11, and the robot body 4 is provided with a rubber strip for cleaning.

[0031] The driving mechanism 2 is fixedly installed at one end of the photovoltaic power station 1 relative to the photovoltaic power station 1. In this embodiment, the driving mechanism 2 is installed at one end of the robot body 4 in the running direction, and the transmission mechanism 3 is two sets, which are respectively arranged at both ends of the photovoltaic power station 1 parallel to the running direction of the robot body 4. The driving mechanism 2 pulls the robot body 4 to move back and forth in the direction of approaching and moving away from the end where the driving mechanism 2 is located through the transmission mechanism 3, and the transmission mechanism 3 is arranged at the opposite ends of the robot body 4.

[0034] The photovoltaic power station cleaning robot system is provided with a detection device, which includes a sensor 24 and a detection disk 23. The detection disk 23 is fixedly assembled on the drive shaft 22. The detection disk 23 is provided with a number of through holes arranged in a ring, and the sensor 24 is an infrared sensor. During the rotation of the detection disk 23, the through hole is detected by the sensor by the drive motor, and the sensor 24 measures the robot movement distance by counting and timing, and controls the movement of the robot according to the program setting. The drive motor 21 and the sensor 24 are powered by the power station self-generated electricity, or they can be connected to the mains power grid in the user's room and powered by the mains power grid. In the preferred embodiment of the present application, the mains power supply is adopted, and the mains power outputs 24V direct current through the AC-DC conversion circuit to power the cleaning system of the present application, so the robot of the present application can continue to work under various meteorological conditions such as light snow, moderate snow, heavy snow, blizzard and sleet, ensuring a better cleaning effect.

[0035] Please continue reading Figure 3 and Figure 4As shown, the robot body 4 includes a walking beam 40 and walking wheels arranged at both ends of the walking beam 40. The walking beam 40 spans across the photovoltaic power station 1 so that the photovoltaic power station 1 can be completely cleaned during one operation. A cleaning member is connected below the walking beam 40. In one embodiment, the cleaning member is, for example, a silicone scraper. In other embodiments, the cleaning member can also be a brush, a rag, etc. The walking wheel is used to roll with the photovoltaic power station 1 when the transmission chain 31 pulls the robot body 4 to move, so as to help the robot body 4 move. The walking wheel includes a positive pressure wheel 41 and a side pressure wheel 42 that are in contact with two vertical surfaces of the photovoltaic power station 1 respectively. In this embodiment, the positive pressure wheel 41 and the side pressure wheel 42 are both in contact with a purlin 11 of the photovoltaic power station 1, the positive pressure wheel 41 contacts the front of the purlin 11, and the side pressure wheel 42 contacts the side of the purlin 11. In actual application scenarios, the photovoltaic power station 1 is tilted up and down, and the side pressure wheel 42 is located on the upper side of the purlin 11 of the photovoltaic power station 1, and is used to hang the robot body 4 to limit the robot body 4 from sliding downward on the photovoltaic power station 1 due to gravity.

[0036] A connecting structure connected to the transmission chain 31 extends from one end of the walking beam 40. In this embodiment, the connecting structure is a connecting ring 43, and the transmission chain 31 also includes a plurality of rings. The connecting ring 43 can be sleeved on the rings of the transmission chain 31. Of course, in other embodiments, the connecting structure is not limited to the connecting ring 43, and it only needs to be able to achieve the connection and fixation between the robot body 4 and the transmission chain 31.

[0037] See also Figures 3 to 5 As shown, the transmission mechanism 3 is installed on the purlin 11 of the photovoltaic power station 1 through a plurality of mounting seats 34. The transmission mechanism 3 includes a transmission wheel 32 and a transmission chain 31. The transmission wheel 32 includes a driving wheel 321 and a driven wheel 322 located at both ends of the photovoltaic power station 1 in the running direction of the robot body 4. The transmission chain 31 is connected in a ring shape and is sleeved on the driving wheel 321 and the driven wheel 322. The driving wheel 321 is the transmission wheel 32 directly driven by the driving motor 21 and the driving shaft 22, and the driven wheel 322 is the transmission wheel 32 that is driven to rotate passively by the transmission chain 31 when the driving wheel 321 rotates. Figure 5 As shown, in this embodiment, the transmission wheel 32 further includes a tensioning wheel 33 disposed between the driving wheel 321 and the driven wheel 322. The tensioning wheel 33 is used to squeeze the transmission chain 31 to keep the transmission chain 31 in a tensioned state to prevent the transmission chain 31 from falling off the transmission wheel 32 due to relaxation.

[0038] Please refer to Figure 6As shown, in this embodiment, the transmission chain 31 is a chain formed by connecting a plurality of metal rings in a string. In this embodiment, the metal ring is a long strip-shaped ring, such as a runway-shaped ring or an elliptical ring. The metal rings are interlocked, and when in a tensioned state, the metal rings alternate between a horizontal posture and a vertical posture. That is, the metal rings on the chain have a horizontal ring 311 and a vertical ring 312, and the horizontal rings 311 and the vertical rings 312 are alternately arranged, wherein a tooth space is formed between the two ends of the two adjacent horizontal rings 311 that are close to each other and the side of the longitudinal ring 312 located therebetween, and the plurality of transmission teeth 320 arranged on the transmission wheel 32 mesh with the tooth space for transmission. In this application, the transmission chain 31 adopts a metal chain, which is a common product and can be directly purchased and applied, and is convenient to use and low in cost; moreover, this application cleverly uses the space between the horizontal and vertical rings of the metal chain as the space for the transmission teeth 320 of the transmission wheel 32 to mesh, and designs a transmission wheel 32 that cooperates with the chain. Please refer to Figure 3 or Figure 4 As shown, in this embodiment, the transmission gear 320 includes two tooth pieces spaced apart in the axial direction of the transmission wheel 32, and the two tooth pieces are respectively engaged in the tooth spaces on opposite sides of a longitudinal ring 312. Specifically, each transmission wheel 32 can be composed of two wheel plates combined together with a gap, for example, two wheel plates are welded together with a support block in the middle, so that there is a gap between the two tooth pieces of the two wheel plates to accommodate the longitudinal ring 312 of the chain, and the two tooth pieces are located on both sides of the longitudinal ring 312, respectively engaged in the tooth spaces on opposite sides of a longitudinal ring 312. In this embodiment, the two tooth pieces sandwich the longitudinal ring 312, so that the force is more balanced and the engagement is more reliable.

[0039] When in use, the driving motor 21 of the driving mechanism 2 is started, and the driving motor 21 outputs power to drive the two driving shafts 22 to rotate, and the driving shaft 22 drives the driving wheel 321 connected thereto to rotate, and the driving wheel 321 drives the transmission chain 31 and the driven wheel 322 to move; the robot body 4 connected to the transmission chain 31 is pulled and moved by the transmission chain 31 to operate on the photovoltaic power station 1 to clear snow, dust, fallen leaves, bird droppings and other debris on the photovoltaic power station 1; the forward and reverse reciprocating operation of the robot body 4 can be achieved through the forward and reverse rotation of the driving motor 21.

[0040] Through the above description of the specific embodiment, it can be known that the photovoltaic power station cleaning robot system provided by the present application includes a driving mechanism 2, a transmission mechanism 3 and a robot body 4, the robot body 4 is connected to the transmission chain 31 of the transmission mechanism 3, and the driving mechanism 2 drives the transmission chain 31 to transmit, so that the transmission chain 31 pulls the robot body 4 to move on the photovoltaic power station 1, without the need to arrange additional tracks, and the driving mechanism 2 and the photovoltaic power station 1 are relatively fixed in position, and do not need to follow the robot body 4 to run, thereby reducing the weight of the robot body.
