Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module handling and lifting devices, and particularly to a handling and lifting device for photovoltaic module installation. Background Art

[0002] Photovoltaic modules are the core part of a solar power generation system and also the most important part. Their function is to convert solar energy into electrical energy, which is then sent to a storage battery for storage or used to drive a load.

[0003] Currently, when installing photovoltaic modules, sometimes installations at a certain height are required. Since photovoltaic modules themselves are relatively heavy, when installing at a high place, a lifting device is needed to handle them. Commonly, a winch is used in combination with a lifting rope to lift and handle photovoltaic modules. The winch is driven by a motor to rotate, thereby winding and unwinding the lifting rope to handle the photovoltaic modules. However, when the photovoltaic module is lifted to a certain height, if the motor fails and the winch cannot be locked, the winch will rotate freely under the weight of the photovoltaic module, and then the photovoltaic module will fall, resulting in damage to the photovoltaic module. If there are workers standing below at this time, the falling photovoltaic module may injure the workers, thus triggering a safety accident.

Detailed implementation manners

[0018] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0019] Refer to Figures 1-9 , a handling and lifting device for installing photovoltaic modules, including a base 1, a lifting frame 2 is fixedly connected to the upper end of the base 1, two mounting plates 3 are symmetrically and fixedly connected to the upper end of the lifting frame 2, a rotating shaft 4 is rotatably connected to the side walls of the two mounting plates 3 close to each other, a winch 5 is fixedly connected to the side wall of the rotating shaft 4, a lifting rope 6 is wound around the side wall of the winch 5, a plurality of fixing ropes 7 are fixedly connected to the lower end of the lifting rope 6, a handling plate 8 is fixedly connected to the lower ends of the plurality of fixing ropes 7, a lifting motor 34 is fixedly connected to the side wall of the mounting plate 3, and the output end of the lifting motor 34 penetrates through the side wall of the mounting plate 3 and is fixedly connected to the rotating shaft 4; Falling prevention mechanism, the falling prevention mechanism includes a box body 9 fixedly connected to the side wall of one of the mounting plates 3. A sliding plug 10 is hermetically and slidably connected to the inner wall of the box body 9. The upper end of the lifting frame 2 is fixedly connected with a vertical cylinder 11. The box body 9 is communicated with the vertical cylinder 11 through a communicating pipe 15. The inside of the box body 9 is filled with non-Newtonian fluid. A sliding block 12 is slidably connected to the inner wall of the box body 9. Two push rods 13 are symmetrically and fixedly connected to the side wall of the sliding block 12 close to the sliding plug 10. The other ends of the two push rods 13 are both fixedly connected to the sliding plug 10. A reciprocating lead screw 14 is rotatably connected to the inner wall of the box body 9. The side wall of the reciprocating lead screw 14 is threadedly connected to the sliding block 12. One end of the reciprocating lead screw 14 penetrates through the side wall of the mounting plate 3 and is fixedly connected to the rotating shaft 4.

[0020] Further, when the photovoltaic module is lifted to a high altitude, if the lifting motor 34 fails and is damaged at this time, making the rotating shaft 4 unable to be locked, under the gravity of the photovoltaic module, the winch 5 rotates freely, so that the photovoltaic module quickly falls. At this time, the winch 5 drives the rotating shaft 4 to rotate quickly, and then drives the sliding block 12 to slide back and forth quickly, making the sliding plug 10 slide back and forth hermetically quickly. Since the photovoltaic module lacks the self-locking of the lifting motor 34 at this time and the lifting motor 34 cannot share the gravity of the photovoltaic module, the gravity of the photovoltaic module is all converted into kinetic energy acting on the sliding plug 10, making the kinetic energy of the sliding plug 10 greatly increase, and then a huge pressure will be instantly generated on the non-Newtonian fluid, making the non-Newtonian fluid change from a liquid state to a solid state. At this time, the non-Newtonian fluid cannot be discharged through the communicating pipe 15, so that the sliding plug 10 and the sliding block 12 cannot slide, and the reciprocating lead screw 14 cannot rotate, so that the rotating shaft 4 is quickly locked and cannot rotate, and the winch 5 cannot rotate, and the suspension rope 6 will immediately stop moving. Then the carrying plate 8 will quickly hover, making the photovoltaic module unable to continue to fall. Therefore, when the lifting motor 34 is damaged, it can prevent the photovoltaic module from falling quickly and causing impact damage, and also avoid the falling photovoltaic module from injuring workers, and the safety performance is higher.

[0021] A rust removal mechanism is installed on the lifting frame 2. The rust removal mechanism includes a mounting groove 16 opened at the inner top of the lifting frame 2. The suspension rope 6 passes through the mounting groove 16. A first annular T-groove 17 is opened at the inner top of the mounting groove 16. Two first T-shaped rods 18 are symmetrically and slidably connected to the inner wall of the first annular T-groove 17. The lower ends of the two first T-shaped rods 18 are fixedly connected together with a friction ring 19. The inner wall of the friction ring 19 is attached to the side wall of the suspension rope 6.

[0022] A driving mechanism is installed in the mounting groove 16. The driving mechanism includes a circular groove 20 opened on the inner wall of the mounting groove 16. A second annular T-groove 21 is opened at the inner top of the circular groove 20. Two second T-shaped rods 22 are symmetrically and slidably connected to the inner wall of the second annular T-groove 21. The lower ends of the two second T-shaped rods 22 are fixedly connected together with a first gear 23. A second gear 24 is fixedly connected to the side wall of the friction ring 19. The first gear 23 is meshed with the second gear 24.

[0023] The driving mechanism further includes a sliding plate 25 that is hermetically slidably connected to the inner wall of the vertical cylinder 11. A rifled rod 26 is fixedly connected to the lower end of the sliding plate 25. The lower end of the rifled rod 26 extends into the circular groove 20. The side wall of the rifled rod 26 is threadedly connected to the first gear 23. A vertical groove 27 is opened at the bottom of the circular groove 20. The lower end of the rifled rod 26 extends into the vertical groove 27.

[0024] Further, during the lifting process, the rotation of the rotating shaft 4 will synchronously drive the reciprocating lead screw 14 to rotate, thereby driving the slider 12 to reciprocate in the box body 9. The slider 12 will drive the sliding plug 10 to reciprocate and seal in the box body 9 through the push rod 13. At this time, the non-Newtonian fluid in the box body 9 will circulate into and out of the vertical cylinder 11 through the connecting pipe 15, so that the sliding plate 25 reciprocates and seals. At this time, the sliding plate 25 will drive the rifled rod 26 to move up and down reciprocally, thereby driving the first gear 23 to rotate forward and backward reciprocally, driving the second gear 24 to rotate forward and backward, and then driving the friction ring 19 to rotate forward and backward reciprocally, so that friction is generated between the friction ring 19 and the suspension rope 6, thereby grinding off the rust on the surface of the suspension rope 6 and avoiding the influence of rust on the strength of the suspension rope 6.

[0025] A maintenance mechanism is installed in the friction ring 19. The maintenance mechanism includes an oil inlet cavity 28 opened in the friction ring 19. A plurality of oil outlet holes 29 are opened on the inner wall of the oil inlet cavity 28. An oil storage cavity 30 is opened in the lifting frame 2. The vertical cylinder 11 is communicated with the oil storage cavity 30 through a one-way oil inlet pipe 31. The one-way oil inlet pipe 31 only allows the lubricating oil in the oil storage cavity 30 to enter the vertical cylinder 11. The vertical cylinder 11 is communicated with the oil inlet cavity 28 through a one-way oil supply pipe 32. The one-way oil supply pipe 32 is made of a flexible pipe, and the one-way oil supply pipe 32 only allows the lubricating oil in the vertical cylinder 11 to enter the oil inlet cavity 28.

[0026] It should be noted that one end of the connecting pipe 15 is communicated with the upper space of the sliding plate 25 in the vertical cylinder 11, while one ends of the one-way oil inlet pipe 31 and the one-way oil supply pipe 32 are both communicated with the lower space of the sliding plate 25 in the vertical cylinder 11 (as Figure 5 、 Figure 6 shown).

[0027] The oil storage cavity 30 is filled with lubricating oil, and an oil injection pipe 33 is fixedly connected to the inner wall of the oil storage cavity 30. An electromagnetic valve is installed on the inner wall of the oil injection pipe 33. By energizing the electromagnetic valve to open it, lubricating oil can be replenished into the oil storage cavity 30 through the oil injection pipe 33.

[0028] Further, when the skateboard 25 reciprocates and seals and slides, the lubricating oil in the oil storage cavity 30 will be pumped into the vertical cylinder 11 through the one-way oil inlet pipe 31. Then, the lubricating oil in the vertical cylinder 11 will enter the oil inlet cavity 28 through the one-way oil supply pipe 32. Finally, the lubricating oil will flow out through multiple oil outlet holes 29 and be applied to the surface of the suspension rope 6. With the friction of the friction ring 19, the rust removal effect can be improved, and the lubricating oil can also play a maintenance role for the suspension rope 6 and reduce the generation of rust.

[0029] An auxiliary mechanism is installed on the mounting plate 3. The auxiliary mechanism includes a cross plate 35 fixedly connected to the side wall of one of the mounting plates 3. A hollow rotating shaft 36 is rotatably connected to the side wall of the cross plate 35. A third gear 37 is fixedly connected to the side wall of the hollow rotating shaft 36. A fourth gear 38 is fixedly connected to the side wall of the rotating shaft 4. The third gear 37 is meshed with the fourth gear 38.

[0030] The auxiliary mechanism further includes an auxiliary motor 39 fixedly connected to the upper end of the cross plate 35 through a bracket. The output end of the auxiliary motor 39 is fixedly connected with a rotating rod 40. The rotating rod 40 extends into the hollow rotating shaft 36. Two grooves 41 are symmetrically opened on the side wall of the rotating rod 40 located in the hollow rotating shaft 36. Magnetic rods 42 are slidably connected to the inner walls of the two grooves 41. A plurality of clamping grooves 43 matched with the magnetic rods 42 are opened on the inner wall of the hollow rotating shaft 36. A first spring 45 is fixedly connected between the inner wall of the groove 41 and the magnetic rod 42.

[0031] The auxiliary mechanism further includes a rectangular plate 46 sealingly and slidably connected to the inner wall of the box body 9. A plurality of second springs 47 are fixedly connected between the rectangular plate 46 and the inner wall of the box body 9. An extrusion block 48 is fixedly connected to the side wall of the rectangular plate 46. A delay switch 49 is fixedly connected to the inner wall of the box body 9. An electromagnet 44 is fixedly connected to the inner wall of the groove 41. The auxiliary motor 39, the delay switch 49, the electromagnet 44 and an external power supply are electrically connected through wires.

[0032] It should be noted that the second spring 47 has a relatively large stiffness coefficient. When the non-Newtonian fluid is in a liquid state, when the non-Newtonian fluid is reciprocally extruded and pumped out under the action of the sliding plug 10, the pressure generated at this time cannot compress the second spring 47. When the photovoltaic module drops and generates a huge pressure to make the non-Newtonian fluid become solid, the pressure at this time can compress the second spring 47.

[0033] Further, in addition, when the non-Newtonian fluid becomes solid, when the sliding plug 10 extrudes the non-Newtonian fluid, it will cause the non-Newtonian fluid to extrude the rectangular plate 46, causing the rectangular plate 46 to move a certain distance to the right (such as Figure 7As shown in the figure, it drives the extrusion block 48 to move to the right, causing the extrusion block 48 to squeeze the delay switch 49. At this time, the delay switch 49 is turned on (it will automatically turn off after a three-minute delay after being turned on), thereby enabling the auxiliary motor 39 and the electromagnet 44 to be energized. When the electromagnet 44 is energized, it generates a magnetic repulsive force, pushing the magnetic rod 42 to move into the card slot 43. And when the auxiliary motor 39 is energized, it drives the rotating rod 40 to rotate, thereby driving the hollow rotating shaft 36 to rotate, driving the third gear 37 to rotate, driving the fourth gear 38 to rotate, and thus driving the rotating shaft 4 and the winch 5 to rotate. Due to the intervention of the auxiliary motor 39 at this time, part of the gravity of the photovoltaic module will be shared by the output shaft of the auxiliary motor 39. Furthermore, at this time, the pressure of the sliding plug 10 on the non-Newtonian fluid decreases and returns to the pressure during normal lifting. At this time, the non-Newtonian fluid will change from a solid state back to a liquid state due to the decrease in pressure and can flow normally. Furthermore, the sliding plug 10 can slide reciprocally normally, enabling the winch 5 to rotate normally under the drive of the auxiliary motor 39. At this time, the auxiliary motor 39 drives the winch 5 to pay out the suspension rope 6, causing the hovering photovoltaic module to fall to the ground. Furthermore, it can avoid the situation that the photovoltaic module hovers at a high altitude all the time during the maintenance of the lifting motor 34, increasing the risk of the photovoltaic module falling, and can also further improve the safety of the working environment.

[0034] In the present invention, the photovoltaic module is placed on the upper end of the handling plate 8, and then the lifting motor 34 is driven to operate, driving the rotating shaft 4 to rotate uniformly, thereby driving the winch 5 to rotate uniformly, and thus retracting the suspension rope 6. The suspension rope 6 will drive the handling plate 8 to move upward uniformly through the fixed rope 7, thereby lifting and handling the photovoltaic module to make it reach the specified installation height.

[0035] During the lifting process, the rotation of the rotating shaft 4 will synchronously drive the reciprocating lead screw 14 to rotate, thereby driving the slider 12 to slide reciprocally in the box body 9. The slider 12 will drive the sliding plug 10 to slide reciprocally and seal in the box body 9 through the push rod 13. At this time, the non-Newtonian fluid in the box body 9 will circulate into and out of the vertical cylinder 11 through the connecting pipe 15, thereby causing the sliding plate 25 to slide reciprocally and seal. At this time, the sliding plate 25 will drive the rifled rod 26 to move up and down reciprocally, thereby driving the first gear 23 to rotate forward and backward reciprocally, driving the second gear 24 to rotate forward and backward, and thus driving the friction ring 19 to rotate forward and backward reciprocally, causing friction between the friction ring 19 and the suspension rope 6, thereby grinding off the rust on the surface of the suspension rope 6 and avoiding the influence of rust on the strength of the suspension rope 6.

[0036] In addition, when the sliding plate 25 slides reciprocally and seals, the lubricating oil in the oil storage cavity 30 will be pumped into the vertical cylinder 11 through the one-way oil inlet pipe 31. Then, the lubricating oil in the vertical cylinder 11 will enter the oil inlet cavity 28 through the one-way oil supply pipe 32. Finally, the lubricating oil will flow out through multiple oil outlet holes 29 and be applied to the surface of the suspension rope 6. In cooperation with the friction of the friction ring 19, it can improve the rust removal effect, and the lubricating oil can also play a role in maintaining the suspension rope 6 and reducing the generation of rust.

[0037] When the photovoltaic module is lifted to a high altitude, if the lifting motor 34 fails and is damaged at this time, making the rotating shaft 4 unable to be locked, under the gravity of the photovoltaic module, the winch 5 rotates freely, causing the photovoltaic module to fall rapidly. At this time, the winch 5 drives the rotating shaft 4 to rotate rapidly, and then drives the slider 12 to slide back and forth rapidly, making the sliding plug 10 slide back and forth and seal rapidly. Since the photovoltaic module lacks the self-locking of the lifting motor 34 at this time and the lifting motor 34 cannot share the gravity of the photovoltaic module, all the gravity of the photovoltaic module is converted into kinetic energy acting on the sliding plug 10, greatly increasing the kinetic energy of the sliding plug 10. Then, a huge pressure will be instantly generated on the non-Newtonian fluid, causing the non-Newtonian fluid to change from a liquid state to a solid state. At this time, the non-Newtonian fluid cannot be discharged through the connecting pipe 15, and then the sliding plug 10 and the slider 12 cannot slide, and the reciprocating lead screw 14 cannot rotate, so that the rotating shaft 4 is quickly locked and cannot rotate, and the winch 5 cannot rotate, and the lifting rope 6 immediately stops moving. Then, the handling plate 8 will quickly hover, making the photovoltaic module unable to continue to fall. Therefore, when the lifting motor 34 is damaged, it can prevent the photovoltaic module from falling rapidly and causing impact damage, and also avoid the falling photovoltaic module from injuring workers, with higher safety performance.

[0038] In addition, when the non-Newtonian fluid becomes solid, when the sliding plug 10 squeezes the non-Newtonian fluid, it will cause the non-Newtonian fluid to squeeze the rectangular plate 46, causing the rectangular plate 46 to move a certain distance to the right (as Figure 7 shown), driving the extrusion block 48 to move to the right, making the extrusion block 48 squeeze the delay switch 49. At this time, the delay switch 49 is turned on (the delay switch 49 will automatically turn off after a three-minute delay after being turned on), and then the auxiliary motor 39 and the electromagnet 44 are energized. The energized electromagnet 44 will generate a magnetic repulsive force, pushing the magnetic rod 42 to move into the card slot 43. And the energized auxiliary motor 39 will drive the rotating rod 40 to rotate, then drive the hollow rotating shaft 36 to rotate, drive the third gear 37 to rotate, drive the fourth gear 38 to rotate, and thus drive the rotating shaft 4 and the winch 5 to rotate. Due to the intervention of the auxiliary motor 39 at this time, part of the gravity of the photovoltaic module will be shared by the output shaft of the auxiliary motor 39. Then, the pressure of the sliding plug 10 on the non-Newtonian fluid decreases and returns to the normal pressure during lifting. At this time, the non-Newtonian fluid will change from a solid state to a liquid state again due to the decrease in pressure and can flow normally. Then, the sliding plug 10 can slide back and forth normally, making the winch 5 rotate normally under the drive of the auxiliary motor 39. At this time, the auxiliary motor 39 drives the winch 5 to pay out the lifting rope 6, making the hovering photovoltaic module fall to the ground. Then, it can be avoided that the photovoltaic module hovers at a high altitude all the time during the maintenance of the lifting motor 34, increasing the risk of the photovoltaic module falling, and can also further improve the safety of the working environment.
