Description

Technical Field

[0001] This utility model belongs to the field of fishery-solar complementary industries, and in particular relates to a photovoltaic power generation panel operation and maintenance platform based on fishery-solar complementary industries. 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 utilization of land resources, allowing for both power generation above and fish farming below. However, this model also presents significant challenges to the daily operation and maintenance of photovoltaic power plants. Currently, maintenance work mainly relies on manual labor using small boats. Maintenance personnel operate on shaky water, which is not only inefficient but also poses serious safety risks such as falling into the water and electric shock. Furthermore, small boats cannot provide a stable and spacious working surface, making tasks such as replacing large components difficult. In addition, the dense photovoltaic arrays also affect traffic and operations in the water below, hindering 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. Utility Model Content

[0014] As described above, the photovoltaic power generation panel operation and maintenance platform based on fishery-solar complementary technology of this utility model has at least the following beneficial effects:

[0015] 1. Creates efficient maintenance and fishing conditions: When the platform is on the water, the sub-maintenance platforms in the same row combine to form a unified maintenance platform, facilitating the positioning of maintenance personnel. When the sub-maintenance platforms in the same row are deployed and partially submerged in the water, they form a continuous "water barrier," automatically separating fish schools below the photovoltaic panels. The "water passage" formed between adjacent rows of maintenance platforms provides a clear and convenient area for net fishing, greatly improving the efficiency of fishing operations.

[0016] 2. Compact structure and high degree of automation: The entire platform integrates multiple functions such as rotation and locking onto the uprights.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0029] 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 this invention. Therefore, they have no substantial technical significance.

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 this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0030] 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.

[0031] Please see Figure 1-2This utility model provides a photovoltaic power generation panel operation and maintenance platform based on fishery-solar complementary systems, including multiple sub-operation and maintenance platforms, each installed on a photovoltaic power generation panel column 1. In the fishery-solar complementary mode, the bottom of the column 1 is located below the water surface, and the top is located above the water surface. The photovoltaic power generation panel and its associated cables are mounted on the column 1 and are located above the water surface. In this embodiment, each column 1 is equipped with a sub-operation and maintenance platform. The sub-operation and maintenance platforms on columns 1 in the same row or column can be combined to form a complete operation and maintenance platform for maintenance personnel to walk on, facilitating routine maintenance or repair. For ease of explanation, the following description uses the example of sub-operation and maintenance platforms on columns 1 in the same row combining to form a complete operation and maintenance platform.

[0032] Each sub-maintenance platform includes two mounting bases 2, two foot pedal platforms 3, and a rotation drive mechanism 4.

[0033] Each of the left and right sides of the column 1 is rotatably equipped with a mounting base 2. The mounting base 2 is mounted on the column 1 via a rotating shaft and bearings. Specifically, the rotating shaft is fixed to the column 1 by welding or other methods. 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 achieving a rotatable connection between the mounting base 2 and the column 1. Each mounting base 2 is equipped with a foot platform 3.

[0034] A rotation drive mechanism 4 is located on the front side of the column 1, and its output end is connected to two mounting bases 2. It drives the two mounting bases 2 to rotate synchronously around the corresponding sides of the column 1, causing the platform 3 to partially submerge underwater. Because the entire platform 3 extends underwater, it forms a water-retaining wall. A water passage is formed between adjacent rows of platform 3, automatically separating the fish located below the photovoltaic panels, facilitating the casting of nets by personnel in the water passage to complete the fishing operation.

[0035] The rotation drive mechanism 4 may include a fixed base 41, a connecting rod assembly 42, a guide seat 43, a telescopic drive member 44, and a guide member 45. The fixed base 41 is disposed on the front side of the column 1, 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 42 is rotatably connected to the two mounting seats 2, and its second end is rotatably connected to the guide seat 43. The telescopic drive member 44 and the guide member 45 are disposed on the front side of the column 1, and the guide seat 43 is slidably connected to the guide member 45 and connected to the output end of the telescopic drive member 44. The telescopic drive member 44 drives the guide seat 43 to slide up and down, so as to synchronously drive the two mounting seats 2 to rotate around the corresponding sides of the column 1 via the connecting rod assembly 42.

[0036] The telescopic drive component 44 can be a telescopic drive element such as a cylinder or an electric cylinder, the guide component 45 can be a guide rail, and the guide seat 43 is slidably connected to the guide component 45 through a slider.

[0037] like Figure 1-4 As shown, when the upper side of the fixed seat 41 abuts against the lower side of the mounting seat 2, due to the downward force of the telescopic drive component 44 and the upward force of the fixed seat 41 on the mounting seat 2, the mounting seat 2 will not rotate relative to the connection point with the column 1, thus ensuring the stability of the maintenance platform.

[0038] Specifically, the linkage assembly 42 may include a first linkage 421, two second linkages 422, two third linkages 423, and a tension spring 424. The mounting base 2 is provided with a first through hole 21; the upper side of the fixed base 41 is provided with a U-shaped groove 411 for accommodating the two mounting bases 2. Second through holes 412 are respectively provided on the two side walls of the U-shaped groove 411, and the portions of the two side walls of the U-shaped groove 411 above the second through holes 412 are inclined surfaces facing the telescopic drive component. The lower side of the mounting base 2 abuts against the upper side of the fixed base 41, that is, when the mounting base 2 is located within the U-shaped groove 411 and abuts against the bottom of the U-shaped groove 411, the first through hole 21 and the second through hole 412 are coaxially arranged.

[0039] The first end of the first connecting rod 421 is rotatably connected to the guide seat 43, specifically by a hinge, and the second end is rotatably connected to the two second connecting rods 422, also by a hinge. The first connecting rod 421 and the two second connecting rods 422 form a "Y"-shaped structure; the third connecting rod 423, the second connecting rods 422, and the mounting seat 2 are arranged in a one-to-one correspondence.

[0040] Each third link 423 has its first end simultaneously fitted with the first through hole 21 and the second through hole 412 with clearance, and its second end rotatably connected to the corresponding second link 422. The second end of the third link 423 and the corresponding second link 422 can be hinged. The first end of the third link 423 is hemispherical. Two ends of a tension spring 424 are respectively connected to the second end of one of the third links 423. The tension spring 424 is used to give the two third links 423 a tendency to exit the second through hole 412.

[0041] The guide seat 43 has a first position and a second position, with the first position located below the second position. In the first position, the first end of the third link 423 is inserted into the corresponding first through hole 21 and second through hole 412; the two second links 422 are in an "open" state, the plane containing the first link 421 and the second link 422 is not parallel to the front side of the column 1, and the tension spring 424 is in a stretched state. It can be understood that the downward force exerted by the telescopic drive member 44 on the guide seat 43 at this time can keep the retaining spring stretched, ensuring that the second end of the third link 423 remains inserted into the second through hole 412.

[0042] When the telescopic drive 44 moves the guide seat 43 from the first position to the second position, that is, when the telescopic drive 44 moves the guide seat 43 upward, the first end of the first link 421 rotates relative to the guide seat 43, and the first ends of the two second links 422 rotate relative to the second end of the first link 421, with the second ends of the two second links 422 rotating towards each other. This causes the second link 422 to drive the third link 423 to overcome the restoring force of the tension spring 424 and exit the second through hole 412. After the third link 423 exits the second through hole 412, when the telescopic drive 44 continues to move the guide seat 43 upward, it causes the mounting base 2 to rotate relative to the column 1, thus submerging part of the platform 3 underwater. It can be understood that when the mounting base 2 rotates, after the third link 423 disengages from the side wall of the U-shaped groove 411, the two third links 423 move in opposite directions due to the restoring force of the tension spring 424.

[0043] When the telescopic drive 44 moves the guide seat 43 from the second position to the first position, the first end of the third link 423 first abuts against the inclined surface of the U-shaped groove 411, compressing the tension spring 424. As the guide seat 43 continues to move downward, the first end of the third link 423, under the restoring force of the tension spring 424, extends into the second through hole 412, and at this time, the mounting seat 2 abuts against the fixed seat 41. This fixes the mounting seat 2 to the guide seat 43, ensuring the stability of the maintenance platform.

[0044] The second end of the first link 421 is also provided with a limiting stop 4211 for limiting the opening angle of the two second links 422, such as Figure 5-6 As shown, there are two limiting blocks 4211. One limiting block 4211 is located on the left side of the second end of the first connecting rod 421, used to limit the rotation angle of the second connecting rod 422 on the left. The other limiting block 4211 is located on the right side of the second end of the first connecting rod 421, used to limit the rotation angle of the second connecting rod 422 on the right. By setting the limiting blocks 4211, it can be ensured that under the action of the restoring force of the tension spring 424, the two third connecting rods 423 extend into the first through hole 21 and the second through hole 412 to the same length.

[0045] To prevent the third link 423 from disengaging from the first through hole 21 during the upward movement of the guide seat 43 driven by the telescopic drive member 44, in one implementation, after the third link 423 exits from the second through hole 412, the second ends of the two third links 423 abut together, at which point the second ends of the two second links 422 will not continue to rotate towards each other. Specifically, each third link 423 has a receiving hole 4231 at its second end, and the two ends of the tension spring 424 are respectively connected to the bottom of the receiving hole 4231. When the second ends of the two third links 423 abut together, the tension spring 424 is accommodated within the space formed by the two receiving holes 4231.

[0046] In another implementation, the third link 423 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 412. The diameter of the second through hole 412 is greater than or equal to the diameter of the T-shaped end of the first through hole 21. Thus, after the third link 423 exits from the second through hole 412, it is contained and blocked by the T-shaped end of the first through hole 21, thereby preventing the third link 423 from detaching from the first through hole 21.

[0047] The sub-maintenance platform provided in this embodiment also includes multiple sets of ladder mechanisms 5 that are spaced apart in the vertical direction and rotatably arranged on the rear side of the column 1. The telescopic drive member 44 is also used to drive the ladder mechanisms 5 to rotate, so as to avoid interference between the ladder mechanisms 5 and the platform 3 when it is rotated. The ladder mechanisms 5 are used for maintenance personnel to climb upwards, so that maintenance personnel can perform maintenance on the photovoltaic panels located at the top of the column 1.

[0048] The ladder mechanism 5 includes a fixed post 51, a ladder plate 52, a torsion spring, and a lower limit block 53. The fixed post 51 and the lower limit block 53 are spaced apart on the column 1. The fixed seat 41 and the lower limit block 53 can be fixedly mounted on the rear side of the column 1 by welding or other means. One end of the ladder plate 52 is rotatably connected to the fixed post 51. Specifically, a rotating hole can be provided on one end of the ladder plate 52, into which the fixed post 51 is inserted to achieve a rotatable connection between the ladder plate 52 and the fixed seat 41. The upper side of the lower limit block 53 is used to abut against the lower side of the end of the ladder plate 52 away from the fixed post 51. The torsion spring (not shown in the figure) is sleeved on the fixed post 51, with one end abutting against the ladder plate 52 and the other end abutting against the column 1. It is used to maintain the abutment between the ladder plate 52 and the lower limit block 53.

[0049] To facilitate maintenance personnel stepping on it, the end of the ladder 52 away from the fixed column 51 will extend out from the side of the column 1. This is to prevent the ladder 52 from interfering with the platform 3 when it rotates.

[0050] like Figure 2 , 7 As shown in Figure 9, there are three ladder plate mechanisms 5. The end of the ladder plate 52 in each mechanism 5, away from the fixed column 51, protrudes from the right side of the column 1. The guide seat 43 is equipped with a first abutment block 431 and a connecting plate 432, each corresponding to a ladder plate 52. The connecting plate 432 and the first abutment block 431 are located on the right side of the column 1. The first abutment block 431 protrudes from the rear side of the column 1 and abuts against the lower side of the ladder plate 52. The guide seat 43, the first abutment block 431, and the connecting plate 432 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.

[0051] When the telescopic drive 44 drives the guide seat 43 to move from the first position to the second position, that is, when it moves upward, the first abutting block 431 abuts against the lower side of the end of the ladder plate 52 away from the fixed column 51, so that the ladder plate 52 rotates relative to the fixed column 51, thereby avoiding interference between the ladder plate 52 and the stepping platform 3.

[0052] The sub-maintenance platform provided in this embodiment also includes an upper limit mechanism 6. The upper limit mechanism 6 is installed on the column 1 and is used to abut against the upper side of the end of the ladder plate 52 away from the fixed column 51 to restrict the ladder plate 52 from rotating relative to the fixed column 51, thereby preventing the ladder plate 52 from rotating relative to the fixed column 51 when maintenance personnel step on the rotating end of the ladder plate 52 and the fixed column 51.

[0053] When the telescopic drive 44 drives the guide seat 43 to move from the first position to the second position, the guide seat 43 first releases the upper limit mechanism 6 from restricting the ladder plate 52, and then the first abutting block 431 abuts against the lower side of the ladder plate 52 at the end away from the fixed column 51, so that the ladder plate 52 rotates relative to the fixed column 51.

[0054] Specifically, the upper limit mechanism 6 includes an upper limit block 61, an elastic element 62, a sliding groove 63 disposed on the column 1, and a cover plate 64. The sliding groove 63 is specifically disposed on the right side of the column 1, and has a first opening facing the rear side of the column 1 and a second opening facing the left side of the column 1. The cover plate 64 is used to close the second opening, and a third opening 641 is provided on the cover plate 64.

[0055] The upper limit block 61 includes an upper limit block body 611 and a second abutting block 612. The second abutting block 612 is disposed on one side wall of the upper limit block body 611 and extends out of the slide groove 63 through a third opening 641.

[0056] The elastic element 62 is a spring. One end of the spring abuts against the side wall of the slide groove 63 facing away from the front side of the column 1, and the other end abuts against the upper limit block body 611. The elastic element 62 is used to make the upper limit block body extend out of the first opening so that the upper limit block body 611 abuts against the upper side of the end of the ladder plate 52 away from the fixed column 51.

[0057] The guide seat 43 also includes an unlocking block 433 corresponding to the second abutment block 612, the unlocking block 433 being used to abut against the second abutment block 612. Specifically, as shown... Figure 2 , 7 As shown in Figure 9, there are three unlocking blocks 433, which are integrally formed with the connecting plate 432. The unlocking blocks 433 are located on the front side of the connecting plate 432, and the first abutment block 431 is located on the rear side of the connecting plate 432. The upper end of the unlocking block 433 is an inclined surface, and the lower side is a side parallel to the front side of the column 1. The side of the second abutment block 612 facing the rear side of the column 1 is at least partially inclined and is inclined downward.

[0058] When the telescopic drive 44 moves the guide seat 43 from the first position to the second position, the inclined surface of the unlocking block 433 first abuts against the inclined surface of the second abutting block 612. Then, as the unlocking block 433 continues to move upward, it drives the second abutting block 612 to move towards the front side of the column 1, thereby releasing the restriction on the ladder plate 52. At this time, the elastic member 62 is compressed. As the guide seat 43 continues to move upward, the first abutting block 431 abuts against the lower side of the ladder plate 52, thereby driving the ladder plate 52 to rotate around the fixed column 51 to avoid interference between the ladder plate 52 and the stepping platform 3.

[0059] When the telescopic drive member 44 moves the guide seat 43 from the second position to the first position, the first abutment block 431 moves downward. At this time, the ladder plate 52 is reset under the action of the torsion spring until the lower side of the ladder plate 52 abuts against the upper side of the lower limit block 53. Then, under the action of the elastic member 62, the upper limit block 61 moves towards the rear side of the column 1 until part of the upper limit block 61 extends out of the slide groove 63 through the first opening, thereby realizing that the upper limit block 61 and the lower limit block 53 jointly restrict the rotation of the ladder plate 52.

[0060] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0061] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
