[0036] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0037] AsFigures 1 to 4 As shown in the figure, an embodiment of the present utility model provides a balanced drive system for a traction type photovoltaic panel cleaning machine, including:

[0038] A drive motor 1 electrically connected to the cleaner assembly of the traction type photovoltaic panel cleaning machine;

[0039] A traction wheel 2 connected to the drive motor 1;

[0040] The traction wheel 2 is provided with a first groove 3 and a second groove 4;

[0041] The drive motor 1 is arranged on one side of a fixed bracket 5;

[0042] The other side of the fixed bracket 5 is respectively provided with the traction wheel 2, a first auxiliary pulley 6 and a second auxiliary pulley 7;

[0043] A rope 8 for connecting the traction wheel 2, the first auxiliary pulley 6, the second auxiliary pulley 7, and a plurality of steering pulleys 9 to form a closed-loop running path.

[0044] In this embodiment, the drive motor 1 serves as the power source of the entire drive system, driving the traction wheel 2 to rotate, and being electrically connected to the cleaner assembly to ensure that power can be provided as needed during the cleaning operation.

[0045] The traction wheel 2 has a first groove 3 and a second groove 4, and these two grooves are used to accommodate ropes or chains in different directions to achieve a complex drive path. By rotating, it drives the rope 8 to move, and further drives the cleaner assembly to move on the surface of the photovoltaic panel.

[0046] The fixed bracket 5 provides a stable installation foundation for the drive motor 1, the traction wheel 2, the first auxiliary pulley 6, and the second auxiliary pulley 7.

[0047] The drive motor 1 is installed on one side of the fixed bracket 5, and the traction wheel 2, the first auxiliary pulley 6, and the second auxiliary pulley 7 are installed on the other side to ensure the compactness and efficiency of the drive path.

[0048] The first auxiliary pulley 6 and the second auxiliary pulley 7 change the drive direction of the rope 8 to assist the traction wheel 2 in achieving a closed-loop running path.

[0049] The rope 8 should be made of wear-resistant, corrosion-resistant, and high-strength materials, such as steel wire ropes or synthetic fiber ropes; the rope 8 connects the traction wheel 2, the first auxiliary pulley 6, the second auxiliary pulley 7, and the steering pulleys 9 to form a closed-loop running path, and the movement of the rope 8 drives the cleaner assembly to perform cleaning operations on the surface of the photovoltaic panel.

[0050] The steering pulley 9 further changes the drive direction of the rope 8 to ensure the integrity and continuity of the drive path, and is arranged at the turning point of the drive path or at the position where the direction needs to be changed.

[0051] When the drive motor 1 starts, the traction wheel 2 rotates accordingly. Through the first groove 3 and the second groove 4 of the traction wheel 2, the rope 8 is driven and moves along a preset path. Guided by the first auxiliary pulley 6 and the second auxiliary pulley 7, and redirected by the steering pulley 9, the rope 8 finally forms a closed-loop running path. In this closed-loop path, the movement of the rope 8 drives the cleaner assembly to perform reciprocating or specific trajectory cleaning operations on the surface of the photovoltaic panel.

[0052] In this technical solution, by adopting a new winding method of the steel wire rope on the traction wheel, not only is the problem of insufficient traction power of the steel wire traction transmission system for ultra-wide or overweight cleaners well solved, but also a large traction force is obtained, effectively solving the problem of the steel wire rope crossing at the drive end, which is particularly beneficial for snow removal operations on photovoltaic panels.

[0053] In an alternative embodiment of the present utility model, the plurality of steering pulleys 9 include a first steering pulley 10, a second steering pulley 11, a third steering pulley 12, a fourth steering pulley 13, a fifth steering pulley 14, and a sixth steering pulley 15;

[0054] The first steering pulley 10, the second steering pulley 11, the third steering pulley 12, the fourth steering pulley 13, the fifth steering pulley 14, and the sixth steering pulley 15 are respectively installed at the four corners of the frame 17.

[0055] In this embodiment, the steering pulley system includes six steering pulleys (i.e., the first steering pulley 10, the second steering pulley 11, the third steering pulley 12, the fourth steering pulley 13, the fifth steering pulley 14, and the sixth steering pulley 15). Each pulley plays an important role in changing the transmission direction of the rope 8. This multi-pulley design allows the rope 8 to undergo multiple direction changes during transmission, thereby enabling the construction of a more complex and precise transmission path.

[0056] All six steering pulleys are installed at the four corners of the frame 17. This layout can maximize the utilization space of the frame 17 and ensure the continuity and stability of the transmission path; specifically, one or more steering pulleys may be installed at each corner, and the specific number depends on the requirements of the transmission path and the design of the frame.

[0057] The frame 17 serves as the installation base for the steering pulleys 9 and other possible components (such as the drive motor 1, the traction wheel 2, etc.), ensuring the stability of the entire transmission system; the design of the frame 17 should consider the overall layout, weight distribution, and stability requirements of the transmission system. At the same time, it also needs to provide sufficient installation points and space to accommodate all necessary components.

[0058] This design of the multi-steering pulley 9 is particularly suitable for large-scale photovoltaic panel arrays that require high-precision and high-coverage cleaning. By constructing a complex transmission path, the cleaning robot can more flexibly cover all corners of the photovoltaic panels, improving the cleaning effect.

[0059] In summary, by adding multiple steering pulleys 9 and specifically installing them at the four corners of the frame 17, this embodiment provides higher flexibility and the possibility of a more complex transmission path for the balanced transmission system of the traction-type photovoltaic panel cleaning machine.

[0060] In an alternative embodiment of the present utility model, the drive motor 1 drives the first groove 3 to drive the rope 8 through the first auxiliary pulley 6 to the first steering pulley 10, and then the rope 8 sequentially passes through the second steering pulley 11, the third steering pulley 12, the second groove 4, the second auxiliary pulley 7, the fourth steering pulley 13, the fifth steering pulley 14, and the sixth steering pulley 15 and then returns to the first groove 3 to form a closed-loop operation.

[0061] In this embodiment, when the drive motor 1 starts, it drives the first groove 3 of the traction wheel 2 to rotate, and the rope 8 is driven by the first groove 3 to start moving; after the rope 8 leaves the first groove 3, it first passes through the first auxiliary pulley 6, where a direction adjustment or tension adjustment is performed; subsequently, the rope 8 reaches the first steering pulley 10 for the first steering; after passing through the first steering pulley 10, the rope 8 continues to move and sequentially passes through the second steering pulley 11 and the third steering pulley 12. These two pulleys further adjust the transmission direction or height of the rope 8; then, the rope 8 enters the second groove 4 of the traction wheel 2, which is an important turning point in the transmission path; after coming out of the second groove 4, the rope 8 passes through the second auxiliary pulley 7 for another direction or tension adjustment; then, the rope 8 sequentially passes through the fourth steering pulley 13, the fifth steering pulley 14, and the sixth steering pulley 15. These pulleys ensure that the rope 8 can smoothly return to near the starting position. Finally, the rope 8 returns to the first groove 3 of the traction wheel 2 to complete a closed-loop operation. At this time, the drive motor 1 can continue to drive the first groove 3 to rotate, thereby continuously driving the rope 8 and the cleaning robot to perform the cleaning operation.

[0062] The closed-loop operation design ensures the stability of the transmission system, reducing vibrations and noises caused by discontinuous transmission paths or sudden direction changes; by optimizing the transmission path and pulley layout, the transmission efficiency is improved, enabling the cleaning robot to complete the cleaning task more quickly and accurately; the design of the multi-steering pulley allows the transmission path to be adjusted according to the shape and size of the photovoltaic panels, increasing the adaptability and flexibility of the cleaning robot.

[0063] In an alternative embodiment of the present utility model, the fixed bracket 5 includes an integrally formed first part 51 and a second part 52.

[0064] In this embodiment, as Figure 5 shown, the first branch 51 and the second branch 52 are made by an integral molding process, which ensures the strength and stability of the bracket. At the same time, integral molding also reduces the connection points between components, reducing the risk of failure due to loose or broken connections.

[0065] The fixing bracket 5 can be any one of an L shape, a rectangle, a triangle, etc. The optimal choice is an L shape, and various shapes can also be set according to actual needs.

[0066] The L-shaped structure allows the fixing bracket 5 to provide multiple mounting points in a limited space. For example, the first branch 51 may be used to mount the drive motor 1, while the second branch 52 is used to mount the traction wheel 2, the first auxiliary pulley 6, and the second auxiliary pulley 7;

[0067] The L-shaped structure provides a stable mounting foundation, which can effectively support and fix each component of the transmission system; through integral molding and the L-shaped layout, the fixing bracket 5 makes the most of the space, making the entire transmission system more compact and efficient; the integral molding design reduces the number of components and connection points during installation, thus simplifying the installation process and reducing the installation difficulty.

[0068] In an alternative embodiment of the present utility model, the first branch 51 is provided with a first through hole 511 and at least one second through hole 512;

[0069] The first through hole 511 is used for connecting the drive motor 1 and the traction wheel 2;

[0070] The second through hole 512 is used for fixing the fixing bracket 5 to the first auxiliary pulley 6 and the second auxiliary pulley 7.

[0071] In this embodiment, as Figure 5 shown, the first through hole 511 is used to connect the drive motor 1 and the traction wheel 2, usually through some form of coupling, bearing or transmission shaft, which will pass through the first through hole 511 to ensure that the power of the drive motor 1 can be smoothly transmitted to the traction wheel 2; the position of the first through hole 511 is usually determined according to the relative positions of the drive motor 1 and the traction wheel 2 to ensure that they can be accurately aligned and effectively transmit power.

[0072] At least one second through hole 512 is provided, but the specific number will be determined according to actual needs and the design of the fixing bracket 5. More second through holes 512 can provide more fixing points, thereby increasing the stability of the fixing bracket 5.

[0073] The second through-hole 512 is used to fix the first auxiliary pulley 6 and the second auxiliary pulley 7 (as well as other components that may need to be fixed). These pulleys are usually fixed to the fixing bracket 5 by bolts, pins or other fasteners passing through the second through-hole 512.

[0074] The position of the second through-hole 512 is determined according to the installation positions of the first auxiliary pulley 6 and the second auxiliary pulley 7 and the requirements of the transmission path. They need to be accurately positioned to ensure that the pulleys can run smoothly and effectively change the transmission direction of the rope 8.

[0075] In an optional embodiment of the present utility model, at least one third through-hole 521 is provided on the second part 52;

[0076] The third through-hole 521 is used for connecting the fixing bracket 5 and the frame 17.

[0077] In this embodiment, according to the size, shape of the fixing bracket 5 and the structure of the frame 17, the number of the third through-holes 521 can be one or more. Multiple through-holes can provide more connection points, thereby dispersing the connection force and improving the connection stability.

[0078] The main function of the third through-hole 521 is to allow fasteners (such as bolts, screws, etc.) to pass through and firmly fix the second part 52 of the fixing bracket 5 on the frame 17; in this way, the fixing bracket 5 can not only support the key components of the transmission system, but also firmly install the entire transmission system in the working environment through the frame 17.

[0079] The position of the third through-hole 521 is determined according to the structure and layout of the frame 17 to ensure that the fixing bracket 5 can be firmly connected to the frame and meet the operation requirements of the transmission system.

[0080] Firmly connecting the fixing bracket 5 to the frame 17 through the third through-hole 521 can significantly enhance the stability of the entire transmission system and reduce the risk of loosening or damage caused by vibration or impact; a firm connection can ensure that the transmission system maintains stable performance during operation, thereby improving its reliability and service life; the design of the third through-hole 521 makes the installation and maintenance process simpler and faster.

[0081] Nor is it limited to using the third through-hole 521 to fix the fixing bracket 5 to the frame 17. When using a fixing bracket 5 with other shapes, the second through-hole 512 can also be used to fix the fixing bracket 5 to the side wall of the box body.

[0082] In an optional embodiment of the present utility model, the fourth steering pulley 13 and the sixth steering pulley 15 are vertically aligned and set at a preset height;

[0083] The first steering pulley 10 and the third steering pulley 12 are vertically aligned and set at a preset height.

[0084] In this embodiment, the fourth steering pulley 13 and the sixth steering pulley 15 are set to be vertically aligned, and there is a preset height difference between them. This setting can ensure that the rope 8 can maintain a relatively stable transmission direction when passing through these two pulleys, reducing vibrations and noises caused by sudden changes in direction.

[0085] The specific value of the preset height difference will be determined according to the overall design and operating requirements of the transmission system. It may be calculated and selected based on factors such as the diameter of the rope 8, the size of the pulleys, the length of the transmission path, and the required transmission efficiency.

[0086] The first steering pulley 10 and the third steering pulley 12 are also set to be vertically aligned and have a preset height difference. This setting helps to maintain the continuity and stability of the rope 8 during transmission, especially in cases where the transmission direction needs to be changed multiple times.

[0087] Similarly, the specific value of the preset height difference will also be accurately calculated and selected according to the specific requirements of the transmission system.

[0088] By setting the vertical alignment and preset height, the transmission path of the rope 8 can be optimized, reducing unnecessary bending and friction, thereby improving the transmission efficiency; the stable transmission path and pulley layout help to reduce vibrations and noises during transmission, improving the stability of the entire transmission system; the reasonable pulley setting can reduce the risk of failures caused by unreasonable transmission paths or improper pulley layouts, thereby enhancing the reliability of the transmission system.

[0089] In an alternative embodiment of the present utility model, a steering device for the rope 8 is provided on the first steering pulley 10, the second steering pulley 11, the third steering pulley 12, the fourth steering pulley 13, the fifth steering pulley 14, and the sixth steering pulley 15.

[0090] In this embodiment, the main function of the steering device is to guide the rope 8 to turn along a predetermined path and direction when passing through the pulley. They achieve precise control of the transmission direction of the rope 8 by changing the contact point and contact angle between the rope 8 and the pulley.

[0091] The specific structure of the steering device may vary depending on the design of the pulley and the requirements of the transmission system. Generally speaking, they may include some special grooves, recesses, or protrusions and other structures that can closely cooperate with the rope 8 to provide stable steering support; in addition, some steering devices may also include lubricating elements to reduce friction and wear between the rope 8 and the pulley during steering.

[0092] Steering devices are installed on each steering pulley to ensure that the rope 8 is correctly guided when passing through each pulley. Their positions and angles are precisely adjusted according to the design of the transmission path to ensure that the rope 8 can run along the predetermined route.

[0093] By setting up the steering devices, it can be ensured that the rope 8 can be steered along the predetermined path and direction during transmission, thereby improving the transmission accuracy; the lubricating elements in the steering devices help reduce the friction and wear between the rope 8 and the pulleys, extending the service life of the transmission system; the stable steering support can reduce the vibration and fluctuation of the rope 8 during transmission, enhancing the stability of the transmission system.

[0094] In an optional embodiment of the present utility model, the rope 8 can be selected from steel wire ropes or nylon ropes, and the two ends of the rope 8 are tensioned and connected through externally connected elastic materials.

[0095] In this embodiment, the steel wire rope has high strength and wear resistance and can withstand large tensile forces and impacts. It is suitable for application scenarios that require high load-bearing capacity and high reliability, such as heavy machinery and equipment, lifting devices, etc.

[0096] The nylon rope, on the other hand, has a lighter weight, good flexibility and corrosion resistance. It is suitable for application scenarios that require relatively light weight, easy bending and not easy to rust, such as photovoltaic panel cleaning robots, outdoor adventure equipment, etc.

[0097] The externally connected elastic materials achieve the tensioned connection at both ends. This connection method connects the two ends of the rope 8 through the use of elastic materials (such as springs, rubber hoses, etc.) and provides a certain amount of tension at the connection. This tension helps to keep the rope 8 in a taut state during transmission, reducing the risk of reduced transmission efficiency or failure caused by slack.

[0098] The selection of the elastic material should be determined according to the material, diameter of the rope 8 and the specific requirements of the transmission system. They need to have sufficient elasticity and durability to ensure that a stable tension can be maintained during long-term use.

[0099] By selecting different materials of the rope 8 and connection methods, the requirements in different application scenarios can be met, improving the flexibility and adaptability of the transmission system; the tensioned connected rope 8 helps to reduce the energy loss and frictional resistance during transmission, thereby improving the transmission efficiency.

[0100] The stable connection method and the selection of appropriate materials can enhance the reliability of the transmission system, reducing the risk of failure caused by loosening, breakage or wear.

[0101] In an optional embodiment of the present utility model, a support device is provided between the fourth steering pulley 13 and the sixth steering pulley 15;

[0102] A support device is provided between the first steering pulley 10 and the third steering pulley 12.

[0103] In this embodiment, support devices are provided between the fourth steering pulley 13 and the sixth steering pulley 15, and between the first steering pulley 10 and the third steering pulley 12, aiming to improve the stability and reliability of the entire transmission system.

[0104] The support device can effectively fix and support the steering pulley, preventing it from shaking or shifting during the transmission process, so as to ensure that the rope 8 can be stably transmitted along the predetermined path and direction.

[0105] In the transmission system, the steering pulley 9 needs to bear the tensile force from the rope 8 and other external forces. The support device can share these loads, reduce the pressure on a single steering pulley, and extend its service life; the support device can reduce vibrations and noises during the transmission process, improving the running smoothness and comfort of the system.

[0106] The material of the support device should have sufficient strength and stiffness. It can be a rectangular box or other support devices to withstand the loads from the steering pulley and the influence of the external environment. At the same time, the material should also have good corrosion resistance and wear resistance to ensure the reliability of long-term use.

[0107] The structure of the support device should be reasonable to be able to tightly fix and support the steering pulley. When designing, factors such as the size, shape, and installation position of the pulley need to be considered to ensure a tight and stable fit between the support device and the pulley.

[0108] The installation of the support device should be convenient and fast, and facilitate subsequent adjustment and maintenance. During the installation process, it is necessary to ensure the fitting accuracy and coordination between the support device and other parts of the transmission system.

[0109] The driving motor 1 drives the traction wheel 2 to drive the steel wire rope 8 through the upper part of the first groove 3 near the motor to the first steering pulley 10, then to the second steering pulley 11 and then to the third steering pulley 12, and then through the lower part of the second groove 4 near the motor of the traction wheel 2 to the second auxiliary pulley 7 to the fourth steering pulley 13, then to the fifth steering pulley 14 and then to the sixth steering pulley 15 to form a closed-loop operation of the drive system.

[0110] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
