Description

Technical Field

[0001] This invention belongs to the field of solar-fishery integration, and in particular relates to a combined maintenance platform for photovoltaic power generation panels based on solar-fishery integration. Background Technology

[0002] "Solar-aquaculture complementarity" is a new industrial model that combines photovoltaic power generation with aquaculture. By installing photovoltaic panel arrays above fishponds, it achieves efficient use of land resources, allowing for both power generation above and fish farming below. However, this model also presents significant challenges to the daily maintenance and repair of photovoltaic power stations. Currently, the maintenance of such projects mainly relies on the following two methods:

[0003] First, large mobile machinery, such as cranes or lifting platforms, is used. This method has obvious drawbacks: First, the ground in fishpond areas is soft and has poor load-bearing capacity, making it difficult for large equipment to enter and posing a risk of tipping over; second, the space under the photovoltaic panel array is usually covered by water, making it difficult to position the equipment stably; third, the rental and operation costs of large machinery are high, and frequent use is not economical.

[0004] Secondly, maintenance personnel operate from small boats on the water. This method is not only inefficient but also poses serious safety hazards. Workers operating tools and maintaining balance while swaying in the small boat are highly susceptible to accidents such as falling into the water or being electrocuted. Furthermore, small boats cannot provide a stable and spacious working surface, making them unsuitable for maintenance tasks requiring the replacement of large components.

[0005] Furthermore, the dense photovoltaic arrays also affect traffic and operations in the waters below, causing inconvenience for the harvesting of adult fish. Therefore, a comprehensive solution that can simultaneously address the needs of photovoltaic array maintenance and aquaculture harvesting is particularly urgent. Summary of the Invention

When the guide seat is in the first position, the first end of the third link is inserted into the corresponding first and second through holes. When the guide seat is in the second position, the first end of the third link is inserted into the corresponding first through hole.

[0018] As described above, the photovoltaic panel combined maintenance platform based on fishery-solar complementary technology of the present invention has at least the following beneficial effects:

[0019] 1. Achieving a mutually beneficial relationship between maintenance and aquaculture: Through the foldable design of the platform mechanism, during non-maintenance periods, the platform can be folded back to the base, maximizing the water surface area exposed to sunlight. This ensures the photosynthesis of algae and the growth of fish in the pond, truly realizing the ecological and economic benefits of "fishery-solar complementarity." During maintenance or fishing periods, the platform unfolds to form a passageway, with each function operating without interference.

[0020] 2. Creates highly efficient fishing conditions: When the sub-maintenance platforms in the same row or column are deployed and partially submerged in the water, they form a continuous "water barrier" that automatically separates the fish schools below the photovoltaic panels. The "water passage" formed between adjacent or same-column platforms provides a clear and convenient area for net fishing, greatly improving the efficiency of fishing operations.

[0021] 3. Compact structure and high degree of automation: The entire platform integrates multiple functions such as telescopic, rotation, and locking onto the base. Through the coordinated work of the telescopic drive mechanism and the second rotation drive mechanism, the pedal mechanism can smoothly and reliably switch between the two states of "retracted above the water surface" and "partially deployed underwater," making operation simple and saving manpower.

[0035] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0036] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0037] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0038] Please see Figure 1-2 This invention provides a combined maintenance platform for photovoltaic power generation panels based on a fish-solar complementary system. The platform includes multiple sub-maintenance platforms, each mounted on a column 1 of a photovoltaic power generation panel. In the fish-solar complementary mode, the bottom of the column 1 is submerged in water, while the top is above water. The photovoltaic power generation panel and its associated cables are mounted on the column 1, also above water. In this embodiment, each column 1 has one sub-maintenance platform. Sub-maintenance platforms on columns 1 in the same row or column can be combined to form a single maintenance platform for maintenance personnel to walk on, facilitating routine maintenance and repairs.

[0039] Please see Figure 1-2 Each sub-maintenance platform includes two mounting bases 2, two telescopic drive mechanisms 3, two sets of pedal mechanisms 4, a first rotation drive mechanism 9, a base 8, and a second rotation drive mechanism 5. The base 8 is rotatably mounted on the column, and the first rotation drive mechanism is mounted on the column, with its output end connected to the base 8 to drive the base 8 to rotate around the column.

[0040] Mounting base 2, telescopic drive mechanism 3, and pedal mechanism 4 are arranged in a one-to-one correspondence. The base 8 has a rectangular structure, and a mounting base 2 is rotatably arranged on the left and right sides of the base 8. The mounting base 2 can be mounted on the base 8 via a rotating shaft and bearings. Specifically, the rotating shaft can be fixed to the base 8 by welding or other means. The inner ring of the bearing is fitted onto the rotating shaft, and the outer ring is connected to the mounting hole on the mounting base 2, thereby realizing the rotatable connection between the mounting base 2 and the base 8.

[0041] The column 1 is a cylindrical structure with a limiting step on its lower side. A through hole is provided at the center of the base 8, through which the base 8 is fitted onto the column. The lower end of the base 8 abuts against the limiting step to achieve positioning of the lower end of the base 8. Understandably, due to the weight of the base itself and the weight of the pedal mechanism and other structures mounted on it, the base will not move upwards along the axis of the column.

[0042] Lubricating grease can be provided on the inner wall of the through hole of the base 8 and the outer wall of the column 1 to facilitate the rotation of the base 8 around the column under the action of the first rotation drive mechanism. Of course, in other implementations, a bearing can also be provided between the base 8 and the column to achieve a rotational connection between the base 8 and the column.

[0043] The first rotation drive mechanism 9 includes a motor 91, a first gear 92, and a second gear 93. The motor 91 is mounted on the column 1. The first gear 92 is coaxially mounted with the output shaft of the motor 91. The second gear 93 is mounted on the base 8 and fixedly connected to it. The first gear 92 and the second gear 93 mesh. The motor 91 drives the first gear 92 to rotate, which in turn drives the second gear 93 to rotate, thereby causing the base 8 to rotate around the column 1. This allows the pedal mechanism to combine with the sub-maintenance platforms in the same row or column to form a complete maintenance platform, facilitating access for maintenance personnel to the bottom of any photovoltaic panel.

[0044] The telescopic drive mechanism 3 is mounted on the mounting base 2. Each set of pedal mechanisms 4 includes multiple pedals 41 connected in series via hinges. The innermost pedal 41 (closest to the column 1) in each set of pedal mechanisms 4 is rotatably connected to the fixed end of the telescopic drive mechanism 3 or to the mounting base 2. The outermost pedal 41 (farthest from the column 1) in each set of pedal mechanisms 4 is rotatably connected to the output end of the telescopic drive mechanism 3. The pedal mechanism 4 has a folded state and an extended state. In the folded state, the multiple pedals 41 of the pedal mechanism 4 overlap and fold together near the corresponding column 1, allowing the water surface to fully receive sunlight penetrating through the gaps between adjacent photovoltaic panels, thus promoting the growth and reproduction of algae in the water. In the extended state, the multiple pedals 41 of the pedal mechanism 4 unfold to form a plane for maintenance personnel to walk on. The telescopic drive mechanism 3 is used to drive the pedal mechanism 4 to move, so that the pedal mechanism 4 can switch between the folded state and the extended state.

[0045] The second rotation drive mechanism 5 is located on the front side of the base 8, and its output end is connected to two mounting seats 2. It is used to drive the two mounting seats 2 to rotate synchronously around the corresponding sides of the base 8, so that the pedal mechanism 4 is partially submerged underwater. In actual use, in order to reduce the resistance of the second rotation drive mechanism 5 during rotation, the second rotation drive mechanism 5 can first drive the pedal mechanism 4, which is in a folded state, to rotate, so that the pedal mechanism 4 is partially submerged underwater. At this time, one end of the pedal mechanism 4 abuts against the bottom of the water, and the other end is on the surface of the water. Then, the telescopic drive mechanism 3 drives the pedal mechanism 4 from the folded state to the unfolded state. At this time, the pedal mechanisms 4 in the same row or column combine to form a maintenance platform, and since the maintenance platform extends underwater, it forms a water barrier. A water passage is formed between adjacent rows or columns of pedal mechanisms 4. During the process of the pedal mechanism 4 changing from folded to unfolded, the fish located under the photovoltaic panels are automatically separated, making it easier for the fishing personnel to cast nets in the water passage to complete the fishing operation.

[0046] like Figure 1-2 As shown, the telescopic drive mechanism 3 includes a multi-stage telescopic rod 31, a scissor-type linkage mechanism 32, and a first telescopic drive member 33. The fixed end of the multi-stage telescopic rod 31 is connected to the mounting base 2, and the movable end is rotatably connected to the outermost pedal 41 of the pedal mechanism 4. The first end of the scissor-type linkage mechanism 32 is rotatably connected to the innermost pedal 41 of the pedal mechanism 4, and the second end is rotatably connected to the outermost pedal 41 of the pedal mechanism 4. The fixed end of the first telescopic drive member 33 is rotatably connected to the mounting base 2, and the movable end is rotatably connected to one of the hinge points in the middle of the scissor-type linkage mechanism 32.

[0047] In this embodiment, each pedal mechanism 4 includes eight pedals 41, with four pedals 41 forming a group. The four pedals 41 in each group are connected in series and hinged together. There are two multi-stage telescopic rods 31, which are spaced apart. Each multi-stage telescopic rod 31 includes a fixed sleeve and multiple telescopic rods slidably disposed within the fixed sleeve. The fixed sleeve and the mounting base 2 can be connected together by welding or bolts. The two middle pedals 41 in each group of pedals 41 are hinged to the telescopic rods in the middle of the multi-stage telescopic rods 31, and the outermost pedal 41 in each group of pedals 41 is hinged to the end of the outermost telescopic rod of the multi-stage telescopic rod 31 away from the fixed sleeve. A scissor linkage mechanism 32 is located between the two groups of pedals 41. The first end of the scissor linkage mechanism 32 is hinged to the innermost pedal 41 in the two groups of pedals 41, and the second end is hinged to the outermost pedal 41 in the two groups of pedals 41. The first telescopic drive component 33 can be a telescopic drive element such as an electric cylinder or a pneumatic cylinder. Its fixed end is hinged to the mounting base 2, and its output end is hinged to one of the hinge points in the middle of the scissor linkage mechanism 32. In this way, the first telescopic drive component 33 can drive the pedal mechanism 4 to change between the unfolded state and the folded state.

[0048] Please see Figure 2-3 The second rotation drive mechanism 5 may include a fixed base 51, a connecting rod assembly 52, a guide seat 53, a second telescopic drive member 54, and a guide member 55. The fixed base 51 is disposed on the front side of the base 8, and its upper side abuts against the lower sides of the two mounting seats 2 to restrict their rotation. The first end of the connecting rod assembly 52 is rotatably connected to the two mounting seats 2, and its second end is rotatably connected to the guide seat 53. The second telescopic drive member 54 and the guide member 55 are disposed on the front side of the base 8, with the guide seat 53 slidably connected to the guide member 55 and connected to the output end of the second telescopic drive member 54. The second telescopic drive member 54 drives the guide seat 53 to slide up and down, so as to synchronously drive the two mounting seats 2 to rotate around the corresponding sides of the base 8 via the connecting rod assembly 52.

[0049] The second telescopic drive component 54 can be a telescopic drive element such as a cylinder or an electric cylinder, the guide component 55 can be a guide rail, and the guide seat 53 is slidably connected to the guide component 55 through a slider.

[0050] Please see Figure 3 When the upper side of the fixed seat 51 abuts against the lower side of the mounting seat 2, due to the downward force of the second telescopic drive member 54 and the upward force of the fixed seat 51 on the mounting seat 2, the mounting seat 2 will not rotate relative to the connection point with the base 8, thus ensuring the stability of the maintenance platform.

[0051] Please see Figure 1-5 Specifically, the linkage assembly 52 may include a first linkage 521, two second linkages 522, two third linkages 523, and a tension spring 524. The mounting base 2 is provided with a first through hole 21; the upper side of the fixed base 51 is provided with a U-shaped groove 511 for accommodating the two mounting bases 2. Second through holes 512 are respectively provided on the two side walls of the U-shaped groove 511. The portions of the two side walls of the U-shaped groove 511 above the second through holes 512 are inclined surfaces facing the second telescopic drive member. The lower side of the mounting base 2 abuts against the upper side of the fixed base 51, that is, when the mounting base 2 is located within the U-shaped groove 511 and abuts against the bottom of the U-shaped groove 511, the first through hole 21 and the second through hole 512 are coaxially arranged.

[0052] The first end of the first connecting rod 521 is rotatably connected to the guide seat 53, specifically by a hinge, and the second end is rotatably connected to the two second connecting rods 522, also by a hinge. The first connecting rod 521 and the two second connecting rods 522 form a "Y"-shaped structure; the third connecting rod 523, the second connecting rods 522, and the mounting seat 2 are arranged in a one-to-one correspondence.

[0053] Each third link 523 has its first end simultaneously fitted with the first through hole 21 and the second through hole 512 with clearance, and its second end rotatably connected to the corresponding second link 522. The second end of the third link 523 and the corresponding second link 522 can be hinged. The first end of the third link 523 is hemispherical. Two ends of a tension spring 524 are respectively connected to the second end of one of the third links 523. The tension spring 524 is used to give both third links 523 a tendency to exit the second through hole 512.

[0054] The guide seat 53 has a first position and a second position, with the first position located below the second position. When the guide seat 53 is in the first position, the first end of the third link 523 is inserted into the corresponding first through hole 21 and second through hole 512; when the guide seat 53 is in the second position, the first end of the third link 523 is inserted into the corresponding first through hole 21. When the second telescopic drive member 54 moves the guide seat 53 from the first position to the second position, the first end of the third link 523 exits the second through hole 512.

[0055] When the guide seat 53 is in the first position, the first end of the third link 523 is inserted into the corresponding first through hole 21 and second through hole 512; the two second links 522 are in the "open" state, the planes of the first link 521 and the second link 522 are not parallel to the front side of the base 8, and the tension spring 524 is in a stretched state. It can be understood that at this time, the downward force of the second telescopic drive member 54 on the guide seat 53 can keep the tension spring in a stretched state, ensuring that the second end of the third link 523 can remain inserted into the second through hole 512.

[0056] When the second telescopic drive member 54 moves the guide seat 53 from the first position to the second position, that is, when the second telescopic drive member 54 moves the guide seat 53 upward, the first end of the first connecting rod 521 rotates relative to the guide seat 53, and the first ends of the two second connecting rods 522 rotate relative to the second end of the first connecting rod 521, and the second ends of the two second connecting rods 522 move towards each other. In this way, the second connecting rod 522 drives the third connecting rod 523 to overcome the restoring force of the tension spring 524 and exit the second through hole 512. After the third connecting rod 523 exits the second through hole 512, when the second telescopic drive member 54 continues to move the guide seat 53 upward, it drives the mounting base 2 to rotate relative to the base 8, thus submerging part of the pedal mechanism 4 underwater. It can be understood that when the mounting base 2 rotates, after the third connecting rod 523 disengages from the side wall of the U-shaped groove 511, due to the restoring force of the tension spring 524, the two third connecting rods 523 move in opposite directions.

[0057] When the second telescopic drive 54 moves the guide seat 53 from the second position to the first position, the first end of the third connecting rod 523 first abuts against the inclined surface of the U-shaped groove 511, compressing the tension spring 524. As the guide seat 53 continues to move downward, the first end of the third connecting rod 523, under the restoring force of the tension spring 524, extends into the second through hole 512, and at this time, the mounting seat 2 abuts against the fixed seat 51. This fixes the mounting seat 2 to the guide seat 53, ensuring the stability of the maintenance platform.

[0058] The second end of the first link 521 is also provided with a limiting stop 5211 for limiting the opening angle of the two second links 522, such as... Figure 7-8 As shown, there are two limiting blocks 5211. One limiting block 5211 is located on the left side of the second end of the first connecting rod 521, used to limit the rotation angle of the second connecting rod 522 on the left. The other limiting block 5211 is located on the right side of the second end of the first connecting rod 521, used to limit the rotation angle of the second connecting rod 522 on the right. By setting the limiting blocks 5211, it can be ensured that under the action of the restoring force of the tension spring 524, the two third connecting rods 523 extend into the first through hole 21 and the second through hole 512 to the same length.

[0059] To prevent the third link 523 from disengaging from the first through hole 21 during the upward movement of the guide seat 53 driven by the second telescopic drive member 54, in one implementation, after the third link 523 exits from the second through hole 512, the second ends of the two third links 523 abut together, at which point the second ends of the two second links 522 will not continue to rotate towards each other. Specifically, each third link 523 has a receiving hole 5231 at its second end, and the two ends of the tension spring 524 are respectively connected to the bottom of the receiving hole 5231. When the second ends of the two third links 523 abut together, the tension spring 524 is accommodated within the space formed by the two receiving holes 5231.

[0060] Please see Figure 5-6 In another implementation, the third link 523 has a T-shaped structure, with its T-shaped end corresponding to the first end; the first through hole 21 is a T-shaped hole, with its T-shaped end facing the second through hole 512. The diameter of the second through hole 512 is greater than or equal to the diameter of the T-shaped end of the first through hole 21. Thus, after the third link 523 exits from the second through hole 512, it is contained and blocked by the T-shaped end of the first through hole 21, thereby preventing the third link 523 from detaching from the first through hole 21.

[0061] Please see Figure 9-10The sub-maintenance platform provided in this embodiment also includes multiple sets of ladder mechanisms 6 that are spaced apart in the vertical direction and rotatably arranged on the rear side of the base 8. The second telescopic drive member 54 is also used to drive the ladder mechanism 6 to rotate, so as to avoid interference between the ladder mechanism 6 and the pedal mechanism 4 when they rotate. The ladder mechanism 6 is used for maintenance personnel to climb upwards, so that maintenance personnel can perform maintenance on the photovoltaic panels located at the top of the base 8.

[0062] The ladder mechanism 6 includes a fixed post 61, a ladder plate 62, a torsion spring, and a lower limit block 63. The fixed post 61 and the lower limit block 63 are spaced apart on the base 8. The fixed base 51 and the lower limit block 63 can be fixed to the rear side of the base 8 by welding or other means. One end of the ladder plate 62 is rotatably connected to the fixed post 61. Specifically, a rotating hole can be provided on one end of the ladder plate 62, into which the fixed post 61 is inserted to achieve a rotatable connection between the ladder plate 62 and the fixed base 51. The upper side of the lower limit block 63 is used to abut against the lower side of the end of the ladder plate 62 away from the fixed post 61. The torsion spring (not shown in the figure) is sleeved on the fixed post 61, with one end abutting against the ladder plate 62 and the other end abutting against the base 8. It is used to maintain the abutment between the ladder plate 62 and the lower limit block 63.

[0063] To facilitate stepping by maintenance personnel, the end of the ladder plate 62 away from the fixed post 61 extends out from the side of the base 8. This is to prevent the ladder plate 62 from interfering with the pedal mechanism 4 when it rotates.

[0064] like Figure 9 As shown, there are three ladder plate mechanisms 6, with one end of the ladder plate 62 away from the fixed post 61 protruding from the right side of the base 8. The guide seat 53 is provided with a first abutment block 531 and a connecting plate 532 corresponding to each ladder plate 62. The connecting plate 532 and the first abutment block 531 are located on the right side of the base 8, with the first abutment block 531 protruding from the rear side of the base 8 to abut against the lower side of the ladder plate 62. The guide seat 53, the first abutment block 531, and the connecting plate 532 can be integrally formed or separately manufactured and then connected together by welding or other methods; this embodiment does not impose any restrictions on this.

[0065] When the second telescopic drive member 54 drives the guide seat 53 to move from the first position to the second position, that is, when it moves upward, the first abutting block 531 abuts against the lower side of the end of the ladder plate 62 away from the fixed column 61, so that the ladder plate 62 rotates relative to the fixed column 61, thereby avoiding interference between the ladder plate 62 and the pedal mechanism 4.

[0066] Please see Figure 9-11The sub-maintenance platform provided in this embodiment also includes an upper limit mechanism 7. The upper limit mechanism 7 is disposed on the base 8 and is used to abut against the upper side of the end of the ladder plate 62 away from the fixed column 61 to restrict the ladder plate 62 from rotating relative to the fixed column 61, thereby preventing the ladder plate 62 from rotating relative to the fixed column 61 when maintenance personnel step on the rotating end of the ladder plate 62 and the fixed column 61.

[0067] When the second telescopic drive member 54 drives the guide seat 53 to move from the first position to the second position, the guide seat 53 first releases the upper limit mechanism 7 from restricting the ladder plate 62, and then the first abutting block 531 abuts against the lower side of the end of the ladder plate 62 away from the fixed column 61, so that the ladder plate 62 rotates relative to the fixed column 61.

[0068] Specifically, the upper limit mechanism 7 includes an upper limit block 71, an elastic element 72, a slide groove 73 disposed on the base 8, and a cover plate 74. The slide groove 73 is specifically disposed on the right side of the base 8, and has a first opening facing the rear side of the base 8 and a second opening facing the left side of the base 8. The cover plate 74 is used to close the second opening, and a third opening 741 is provided on the cover plate 74.

[0069] The upper limit block 71 includes an upper limit block body 711 and a second abutting block 712. The second abutting block 712 is disposed on one side wall of the upper limit block body 711 and extends out of the slide groove 73 through a third opening 741.

[0070] The elastic element 72 is a spring. One end of the spring abuts against the side wall of the slide groove 73 facing away from the front side of the base 8, and the other end abuts against the upper limit block body 711. The elastic element 72 is used to make the upper limit block body part extend out of the first opening so that the upper limit block body 711 abuts against the upper side of the end of the ladder plate 62 away from the fixed column 61.

[0071] The guide seat 53 also includes an unlocking block 533 corresponding to the second abutment block 712, the unlocking block 533 being used to abut against the second abutment block 712. Specifically, as shown... Figure 9-11 As shown, there are three unlocking blocks 533, which are integrally formed with the connecting plate 532. The unlocking blocks 533 are located on the front side of the connecting plate 532, and the first abutment block 531 is located on the rear side of the connecting plate 532. The upper end of the unlocking block 533 is an inclined surface, and the lower side is a side parallel to the front side of the base 8. The side of the second abutment block 712 facing the rear side of the base 8 is at least partially inclined and is inclined downward.

[0072] When the second telescopic drive member 54 moves the guide seat 53 from the first position to the second position, the inclined surface of the unlocking block 533 first abuts against the inclined surface of the second abutting block 712. Then, as the unlocking block 533 continues to move upward, it drives the second abutting block 712 to move towards the front side of the base 8, thereby releasing the restriction on the ladder plate 62. At this time, the elastic member 72 is compressed. As the guide seat 53 continues to move upward, the first abutting block 531 abuts against the lower side of the ladder plate 62, thereby driving the ladder plate 62 to rotate around the fixed column 61 to avoid interference between the ladder plate 62 and the pedal mechanism 4.

[0073] When the second telescopic drive member 54 moves the guide seat 53 from the second position to the first position, the first abutment block 531 moves downward. At this time, the ladder plate 62 is reset under the action of the torsion spring until the lower side of the ladder plate 62 abuts against the upper side of the lower limit block 63. Then, under the action of the elastic member 72, the upper limit block 71 moves towards the rear side of the base 8 until part of the upper limit block 71 extends out of the slide groove 73 through the first opening, thereby realizing that the upper limit block 71 and the lower limit block 63 jointly restrict the rotation of the ladder plate 62.

[0074] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
