Detailed Implementation

[0033] The core of this application is to provide a hoisting tool that improves the cleaning efficiency of photovoltaic modules while reducing the cleaning cost of photovoltaic modules.

[0034] Another core aspect of this application is to provide a photovoltaic cleaning system with the aforementioned hoisting tools.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] During the cleaning of photovoltaic (PV) modules, cable trays are typically used to transfer the cleaning equipment from one module to another. However, in practice, these cable trays require a significant amount of materials and time to construct, increasing costs and reducing cleaning efficiency. Furthermore, when there is a large height difference between adjacent PV modules, the cable trays connecting them may have a significant tilt angle, posing a risk of derailment for the cleaning equipment as it passes over them.

[0037] Meanwhile, in photovoltaic power plants, traditional photovoltaic panels are typically installed using fixed brackets, single-axis horizontal supports, or flexible brackets. Regardless of the method used, to ensure the highest power generation efficiency, the photovoltaic panels usually need to face the sun. For example, fixed brackets have an inclined structure, and single-axis horizontal supports use a tracking system to track the sun's movement in real time. Therefore, the photovoltaic cleaning equipment 300 is usually installed on the photovoltaic panels in an inclined position, and traditional transportation methods cannot meet the actual needs.

[0038] Therefore, such as Figure 1 and Figure 2 As shown in the illustration, this application discloses a hoisting tool 100, including a hoisting base 10, a hoisting device 200, an attitude adjustment component 20, and a clamping component 30. The attitude adjustment component is connected to the hoisting device 200 to adjust the attitude angle between the hoisting tool 100 and the hoisting device 200, thereby ensuring the stability of the photovoltaic cleaning device 300. Simultaneously, the clamping component 300 clamps the photovoltaic cleaning device 300, allowing it to be transferred via the hoisting device 200. This reduces the time required to build the cable tray, improves the cleaning efficiency of the photovoltaic modules, saves materials needed for building the cable tray, reduces the cleaning cost of the photovoltaic modules, and prevents the photovoltaic cleaning device from derailing when passing through the cable tray, ensuring the stability of the photovoltaic cleaning device 300 operation.

[0039] The following will combine Figures 1 to 8 The hoisting tool 100 disclosed in the embodiments of this application will be explained and described in detail.

[0040] Among them, such as Figure 1 and Figure 6 As shown, the hoisting base 10 serves as a connection platform between the hoisting tool 100 and the hoisting equipment 200. It can adopt a plate-like structure to facilitate the connection between the hoisting equipment 200 and the hoisting tool 100, thereby ensuring the stability of the transferred photovoltaic cleaning equipment 300.

[0041] like Figure 2 and Figure 6 As shown, the attitude adjustment component 20 can be installed on the lifting base 10. The lifting tool 100 can be connected to the bottom of the lifting equipment 200 or a dedicated mounting point through the attitude adjustment component 20. The attitude adjustment component 20 can adjust the attitude angle of the lifting tool 100 relative to the lifting equipment 200. This ensures that when the photovoltaic cleaning equipment 300 is in an inclined position, the attitude adjustment component 20 can adjust the attitude angle of the lifting tool 100 relative to the lifting equipment 200 to ensure that the lifting equipment 200 is always parallel to the horizontal plane, thereby ensuring the stability of the lifting equipment 200 in lifting the photovoltaic cleaning equipment 300.

[0042] It should be noted that the lifting equipment 200 can be a drone, allowing the attitude adjustment component 20 to adjust the attitude angle of the lifting tool 100 relative to the drone, ensuring the drone remains parallel to the horizontal plane and thus guaranteeing the stability of the drone in lifting the photovoltaic cleaning equipment 300. The drone can be a multi-rotor drone, such as a quadcopter, hexacopter, or octocopter, possessing sufficient load-bearing capacity and flight stability to carry and transport the photovoltaic cleaning equipment 300. Furthermore, the drone can have a built-in flight control system, power system, navigation and positioning system, and communication module, enabling it to receive commands from the ground station or operators to perform autonomous or remote-controlled flight missions. Alternatively, the lifting equipment 200 can be a mobile vehicle equipped with a robotic arm, using the robotic arm for lifting. The attitude adjustment component 20 can be used to adjust the gripping attitude of the photovoltaic cleaning equipment 300, thereby reducing the control requirements on the robotic arm.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the attitude adjustment assembly 20 may include at least one telescopic cylinder 21 capable of adjusting the pitch attitude of the lifting tool 100. The telescopic cylinder 21 may be hinged to the lifting base 10, and the telescopic rod of the telescopic cylinder 21 may be fixedly connected to the lifting equipment 200. The pitch attitude of the lifting tool 100 relative to the lifting equipment 200 can be adjusted by extending and shortening the telescopic rod of the telescopic cylinder 21. One telescopic cylinder 21 may be used, or two, three, four, or more may be used to achieve multi-attitude adjustment of the lifting tool 100 relative to the lifting equipment 200, thus making it suitable for lifting the photovoltaic cleaning equipment 300 under various working conditions.

[0044] In some embodiments, such as Figure 3 As shown, the attitude adjustment assembly 20 may further include at least one fixed rod 22, i.e., one, two, or more fixed rods 22 may be used, and one telescopic cylinder 21 may be used. The telescopic cylinder 21 may be spaced apart from the fixed rods 22 along a first direction, and one end of the fixed rod 22 is connected to the lifting base 10, while the other end of the fixed rod 22 can be hinged to the lifting equipment 200. This allows for adjustment of the pitch attitude of the lifting tool 100 relative to the lifting equipment 200 by extending and retracting the telescopic rod of the telescopic cylinder 21. It should be noted that the first direction is perpendicular to the direction of movement of the photovoltaic cleaning equipment 300, and the second direction is parallel to the direction of movement of the photovoltaic cleaning equipment 300.

[0045] In some embodiments, two telescopic cylinders 21 may be used, and in the first direction, the two telescopic cylinders 21 are respectively located on both sides of the fixed rod 22, so as to realize the multi-posture adjustment of the lifting tool 100 relative to the lifting equipment 200 by extending and shortening the telescopic rod of the telescopic cylinder 21, thereby being suitable for lifting the photovoltaic cleaning equipment 300 under various working conditions.

[0046] In some embodiments, the attitude adjustment assembly 20 may include a universal joint. Specifically, the attitude adjustment assembly 20 may employ a dual-axis universal joint. The dual-axis universal joint is mounted on the bottom of the lifting equipment 200, while the lifting base 10 of the lifting tool 100 is mounted on the output end of the dual-axis universal joint. Simultaneously, the dual-axis universal joint integrates at least two independent servo motors, which can respectively control the rotation of the lifting tool 100 around the pitch axis and roll axis, thereby enabling multi-attitude adjustment of the lifting tool 100 relative to the lifting equipment 200, thus making it suitable for lifting the photovoltaic cleaning equipment 300 under various working conditions.

[0047] like Figure 1 and Figure 6 As shown, the clamping assembly 30 can be mounted on the lifting base 10 to clamp the photovoltaic cleaning device 300. The clamping assembly 30 may include at least two clamping elements 31 and a power assembly 32. The at least two clamping elements 31 can be symmetrically arranged on the side of the lifting base 10 opposite to the attitude adjustment assembly 20; that is, two clamping elements 31 can be used, symmetrically arranged on both sides of the lifting base 10. Alternatively, four, six, or more clamping elements 31 can be used, thereby improving the stability and reliability of clamping the photovoltaic cleaning device 300. Simultaneously, the power assembly 32 is mounted on the lifting base 10 and can drive at least two clamping elements 31 to move synchronously towards or away from each other to clamp or release the photovoltaic cleaning device 300.

[0048] When the photovoltaic cleaning equipment 300 needs to be moved, the lifting tool 100 can be hoisted above the photovoltaic cleaning equipment 300 using a hoisting device 200 such as a drone. At this time, the power component 32 drives at least two clamping parts 31 of the hoisting tool 100 to clamp the crossbeam 303 of the photovoltaic cleaning equipment 300. Then, the photovoltaic cleaning equipment 300 can be lifted and transferred to the target location using the hoisting device 200 such as a drone. It should be noted that the target location can be the location of the photovoltaic modules that need to be cleaned, or it can be the location where the equipment is stopped for maintenance.

[0049] In some embodiments, such as Figure 1 and Figure 6As shown, the power assembly 32 may include a transmission component 321 and a drive component 322. The drive component 322 can be connected to the clamping component 31 through the transmission component 321, so that under the drive of the drive component 322, the transmission component 321 can drive at least two clamping components 31 to move synchronously towards or away from each other, thereby realizing the clamping or release of the crossbeam 303 of the photovoltaic cleaning device 300.

[0050] In some embodiments, such as Figure 1 and Figure 6 As shown, the power assembly 32 may also include a guide 323, and at least two clamping members 31 may move along the trajectory defined by the guide 323, thereby ensuring the stability and reliability of the clamping members 31 clamping the photovoltaic cleaning device 300.

[0051] In some embodiments, such as Figures 1 to 3 As shown, the clamping member 31 may include a first mating part 311, and at least two clamping members 31 have their first mating parts 311 arranged opposite each other. That is, the first mating parts 311 are provided on the inner side of at least two clamping members 31. The first mating parts 311 can be adapted to the crossbeam 303 on the photovoltaic cleaning device 300, so that the first mating parts 311 and the crossbeam 303 of the photovoltaic cleaning device 300 can cooperate in the clamping direction to generate a constraint force in at least one direction perpendicular to the clamping direction. That is, a constraint force can be generated in the direction parallel to the crossbeam 303 or in the direction perpendicular to the crossbeam 303. Thus, the constraint force can limit the swaying of the photovoltaic cleaning device 300 during hoisting. It should be noted that the clamping direction is consistent with the second direction, that is, the direction parallel to the movement direction of the photovoltaic cleaning device 300.

[0052] In some embodiments, such as Figures 1 to 3 As shown, the first mating part 311 may include a groove 312 with a strip-shaped structure that is adapted to the crossbeam 303 on the photovoltaic cleaning device 300, so that the groove 312 can have a larger contact area with the crossbeam 303, preventing the photovoltaic cleaning device 300 from shaking during the hoisting process due to its own slender structure, and ensuring the stability of the photovoltaic cleaning device 300 during the hoisting process.

[0053] In some embodiments, such as Figure 3 As shown, second mating parts 301 are respectively provided on both sides of the crossbeam 303 on the photovoltaic cleaning equipment 300, and the first mating part 311 can cooperate with the second mating part 301 in the clamping direction to generate a constraint force in at least one direction perpendicular to the clamping direction, thereby limiting the swaying of the photovoltaic cleaning equipment 300 during hoisting through the constraint force. Meanwhile, as... Figure 4 and Figure 5As shown, at least one of the first mating part 311 and the second mating part 301 may be provided with friction texture 33. Friction texture 33 can be provided on the first mating part 311 or the second mating part 301, or both the first mating part 311 and the second mating part 301 may be provided with friction texture 33 to improve the reliability of clamping. The friction texture 33 can be a fine mesh, knurled pattern, or parallel grooves to significantly increase the static friction coefficient between the contact surfaces, thereby generating greater frictional force under the same clamping force. This effectively prevents the photovoltaic cleaning device 300 from slipping in the vertical direction (i.e., the direction of gravity), further improving the safety and stability of lifting.

[0054] In some embodiments, such as Figures 3 to 5 As shown, the second mating part 301 may include a protrusion 302 that can mate with the groove 312. Simultaneously, a first inclined surface 3121 may be provided in at least one direction on the inner wall of the groove 312, that is, the first inclined surface 3121 may be provided in one direction on the inner wall of the groove 312, or it may be provided in two or more directions on the inner wall of the groove 312. At the same time, the protrusion 302 may be provided with a second inclined surface 3021 adapted to the first inclined surface 3121, that is, the second inclined surface 3021 may be provided in one direction on the protrusion 302, or it may be provided in two or more directions on the protrusion 302, so that the second inclined surface 3021 abuts against the first inclined surface 3121, thereby generating a restraining force that can limit the shaking of the photovoltaic cleaning device 300 during hoisting.

[0055] In some embodiments, such as Figure 4 As shown, the first inclined surface 3121 can be disposed at the end faces and sidewalls of both ends of the groove 312. Specifically, the cross-sectional area of ​​the end face of the groove 312 increases towards the middle region to form the first inclined surface 3121 at the end face of the groove 312, and the cross-sectional area of ​​the sidewall of the groove 312 decreases from the bottom wall of the groove 312 towards the direction away from the bottom wall to form the first inclined surface 3121 at the sidewall of the groove 312. That is, the cross-section of the sidewall of the groove 312 can be trapezoidal. Meanwhile, as... Figure 5As shown, the protrusions 302 can be located at both ends of the second mating part 301. On the inner side of the protrusions 302, that is, on the side opposite to the two protrusions 302, a second inclined surface 3021 adapted to the first inclined surface 3121 of the end face of the groove 312 can be provided. On both sides of the protrusions 302, a second inclined surface 3021 adapted to the first inclined surface 3121 of the side wall of the groove 312 can be provided. That is, the second inclined surface 3021 on the inner side of the protrusions 302 can be an isosceles trapezoid, with the short side located on the side of the protrusions 302 away from the crossbeam 303 and the long side located on the side of the protrusions 302 close to the crossbeam 303. Thus, constraint forces can be generated in the direction parallel to the crossbeam 303 and the direction perpendicular to the crossbeam 303, respectively. The constraint forces can limit the photovoltaic cleaning equipment 300 from swaying in the direction parallel to the crossbeam 303 and the direction perpendicular to the crossbeam 303 during hoisting.

[0056] In some embodiments, such as Figure 1 As shown, the transmission component 321 may include a transmission rod 3211, and the transmission rod 3211 has a first threaded section 3211a and a second threaded section 3211b with opposite directions of rotation. At least two clamping members 31 are respectively threadedly connected to the first threaded section 3211a and the second threaded section 3211b. Meanwhile, the driving component 322 may be a drive motor, so that the driving component 322 drives the transmission rod 3211 to rotate, thereby enabling at least two clamping members 31 to move synchronously towards or away from each other.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, two mounting seats 11 can be provided on the side of the hoisting base 10 away from the attitude adjustment assembly 20, and the two mounting seats 11 are symmetrically arranged on both sides of the hoisting base 10. The mounting seats 11 can adopt an L-shaped structure, that is, the mounting seats 11 have a first mounting part and a second mounting part arranged perpendicularly to each other. The first mounting part of the mounting seat 11 can be detachably connected to the hoisting base 10 by fasteners such as bolts. Simultaneously, both ends of the transmission rod 3211 are rotatably connected to the second mounting parts of the two mounting seats 11 respectively, and the driving member 322 can be fixed to the outside of any one of the mounting seats 11, that is, the side of the two mounting seats 11 facing away from each other, and is connected to the transmission rod 3211 for transmission, so that the driving member 322 can drive the transmission rod 3211 to rotate. Furthermore, the first threaded section 3211a and the second threaded section 3211b of the transmission rod 3211 can be threadedly connected to the movable seat 313, and the two movable seats 313 are respectively connected to the first mating parts 311 of at least two clamping members 31 through the connecting plate 314, so that the driving member 322 drives the transmission rod 3211 to rotate, thereby driving the first mating parts 311 of at least two clamping members 31 to move synchronously towards each other or away from each other through the movable seat 313.

[0058] In some embodiments, such as Figure 1As shown, the guide member 323 may include at least one guide rod 3231, that is, one, two or more guide rods 3231 may be used. The guide rod 3231 can pass through the two movable seats 313, and the two ends of the guide rod 3231 can be fixed to the second mounting part of the two mounting seats 11 respectively, so that the two movable seats 313 can move along the guide rod 3231, ensuring the stability and reliability of the clamping member 31 clamping the photovoltaic cleaning equipment 300.

[0059] In some embodiments, such as Figures 6 to 8 As shown, the clamping member 31 may include at least one hook 317, that is, one, two or more hooks 317 may be used, and the hooks 317 may have an L-shaped structure, that is, the hooks 317 may have a connecting part and a locking part arranged perpendicularly to each other. The connecting part of the hooks 317 may be connected to the transmission member 321 for transmission, so that under the drive of the driving member 322, the transmission member 321 can drive the locking parts of at least two oppositely arranged hooks 317 to extend into or out of the bottom of the crossbeam 303 of the photovoltaic cleaning device 300, so that the locking parts of the hooks 317 can abut against the bottom of the crossbeam 303, thereby lifting the photovoltaic cleaning device 300 and transferring it to the target position.

[0060] In some embodiments, such as Figure 6 and Figure 7 As shown, the transmission component 321 may include a gear 3212 and at least two racks 3213, i.e., there may be two, four or more racks 3213, the specific number of which can be determined according to the number of clamping components 31. The driving component 322 may be a drive motor, and the gear 3212 is driveably connected to the driving component 322. At the same time, the gear 3212 meshes with at least two racks 3213 respectively, and the racks 3213 are driveably connected to the clamping components 31, so that the driving component 322 drives the gear 3212 to rotate, thereby driving the two racks 3213 to move in opposite or opposite directions, and in turn driving the clamping components 31 to move in opposite or opposite directions.

[0061] In some embodiments, such as Figure 6 and Figure 7 As shown, the drive unit 322 can be installed on the hoisting base 10 and on the same side as the attitude adjustment component 20. The gear 3212 is located on the side of the hoisting base 10 away from the attitude adjustment component 20 and is connected to the output shaft of the drive unit 322. At the same time, at least two racks 3213 are respectively fixed with connecting seats 315. The connecting seats 315 can be connected to the connecting part of the hook 317 through the mounting plate 316. By driving the gear 3212 to rotate through the drive unit 322, the two racks 3213 are driven to move in opposite or opposite directions, thereby driving the hook 317 of the clamping member 31 to move in opposite or opposite directions.

[0062] In some embodiments, such as Figure 6and Figure 7 As shown, a support base 12 capable of supporting the transmission components 321 (gear 3212 and rack 3213) may be provided on the side of the hoisting base 10 away from the attitude adjustment assembly 20. The support base 12 may have a plate-like structure, and the support base 12 and the hoisting base 10 may be connected and fixed together by multiple connecting posts 13. Meanwhile, the guide member 323 may include a sliding hole 3232 provided on the support base 12, and the sliding hole 3232 is adapted to the rack 3213. A connecting seat 315 is located on the side of the support base 12 away from the hoisting base 10, so that the rack 3213 can extend out of the sliding hole 3232 and connect with the connecting seat 315, thereby allowing the rack 3213 to move along the sliding hole 3232, ensuring the stability and reliability of the clamping member 31 in holding the photovoltaic cleaning equipment 300. It should be noted that the sliding hole 3232 can be a strip-shaped hole with a certain length, such as an oblong hole or a rectangular hole, to ensure that the rack 3213 can move along the sliding hole 3232.

[0063] The hoisting tool 100 disclosed in this application embodiment can be connected to the hoisting equipment 200 through the attitude adjustment component 20 disposed on the hoisting base 10. The attitude adjustment component can adjust the attitude angle between the hoisting tool 100 and the hoisting equipment 200. At the same time, the power component 32 of the clamping component 30 can drive at least two clamping members 31 to move synchronously towards or away from each other to clamp or release the photovoltaic cleaning equipment 300. Then, the photovoltaic cleaning equipment 300 can be transferred by the hoisting equipment 200.
