Technical Field

[0001] This application relates to the field of photovoltaic power plant technology, and in particular to a maintenance and operation platform. Background Technology

[0002] When a photovoltaic (PV) power station is built on water, maintenance personnel need to maintain it through an operation and maintenance platform. However, PV power stations are often large in scale, and the existing maintenance platform can only inspect a limited area when docked. If maintenance is required on PV equipment in different locations within the power station, the maintenance platform needs to be frequently activated, leading to inconvenience in operation and maintenance. Utility Model Content

[0003] The main purpose of this application is to propose a maintenance and repair platform that aims to solve the problem of inconvenience in the operation and maintenance of existing maintenance and repair platforms.

[0004] To achieve the above objectives, this application proposes a maintenance and operation platform for photovoltaic power plants, the maintenance and operation platform comprising:

[0005] Float assembly;

[0006] A mobile carrier is movably and switchably disposed on the pontoon assembly at least between two positions;

[0007] The top of the mobile carrier serves as a work surface.

[0008] In one embodiment, the float assembly includes a first float and a second float disposed opposite to each other along a first direction;

[0009] The mobile carrier is slidably and switchably disposed between the first pontoon and the second pontoon along a second direction, the second direction intersecting the first direction.

[0010] In one embodiment, a sliding component is provided between the mobile carrier and the float assembly, and the mobile carrier slides relative to the first float and / or the second float via the sliding component.

[0011] In one embodiment, the sliding assembly is provided between the mobile carrier and the first pontoon, and the mobile carrier and the second pontoon slide relative to the first pontoon;

[0012] Alternatively, the sliding assembly is provided between the mobile carrier and the second pontoon, and the mobile carrier and the first pontoon slide relative to the second pontoon;

[0013] Alternatively, the sliding assembly may be provided between the mobile carrier and the first pontoon, and between the mobile carrier and the second pontoon, and the mobile carrier may slide relative to the first pontoon and the second pontoon.

[0014] In one embodiment, the pontoon assembly further includes a connecting plate, with the first pontoon and the second pontoon disposed opposite each other on both sides of the connecting plate.

[0015] In one embodiment, the sliding assembly includes a first slider and a second slider, one of which is a slide rail, and the other is a slider that is slidably adapted to the slide rail. The slider is slidably mounted on the slide rail and slides back and forth along the slide rail.

[0016] The mobile carrier is provided with the first sliding member, and the first float and / or the second float is provided with the second sliding member;

[0017] And / or, the mobile carrier is provided with the first sliding member, and the connecting plate is provided with the second sliding member.

[0018] In one embodiment, the maintenance platform further includes a ladder, which is rotatably mounted on the float assembly, and the ladder is used to adjust the opening angle accordingly during rotation;

[0019] The maintenance and repair platform also includes a rotating base, which is connected to the mobile carrier and is used to drive the ladder to rotate.

[0020] In one embodiment, the maintenance platform further includes a pedal, and the mobile carrier is provided with a mounting slot for the pedal to be detachably installed.

[0021] In one embodiment, the photovoltaic power station includes a column, and a limiting part is provided on the periphery of the float assembly. A limiting space is formed in the middle of the limiting part to constrain the column.

[0040] When a photovoltaic power station is built on a body of water, it can be used as a surface photovoltaic power station. Surface photovoltaic power stations, as a type of photovoltaic power generation system built on water, can be constructed on ponds, fishponds, small to medium-sized lakes, reservoirs, water storage ponds, and lakes formed by coal mining subsidence areas. Generally, surface photovoltaic power stations are mainly divided into two categories: pile-based fixed type and floating type. Among them:

[0041] Pile-foundation type: Suitable for waters with shallow water levels, no risk of geological disasters such as subsidence, and minimal water level fluctuations. This type of power station uses underwater piles to fix the photovoltaic modules.

[0042] Floating type: Suitable for waters deeper than 3 to 5 meters, with relatively stable water bodies and minimal impact from typhoons. Floating power stations use specially designed floats to support the photovoltaic modules, allowing them to float on the water surface.

[0043] Maintenance and repair platforms are used for the maintenance of floating photovoltaic (PV) power stations. Generally, maintenance personnel need to use these platforms to perform maintenance. However, most existing maintenance and repair platforms are ship-shaped structures, while floating PV power stations are typically large. When the platform is docked, maintenance personnel can only access the side of the PV power station that is in contact with the platform's hull. This limits the area that can be inspected when the platform is docked. Furthermore, when maintenance is required on PV equipment in different locations within the power station, the platform needs to be frequently activated, leading to inconvenience in maintenance and repair.

[0044] Reference Figures 1 to 5 This application proposes a maintenance and operation platform for photovoltaic power plants. The maintenance and operation platform includes a float assembly 100 and a mobile carrier 200. The mobile carrier 200 is movably and switchably disposed on the float assembly 100 at least between two positions, and the top of the mobile carrier 200 serves as a work surface.

[0045] In the embodiments of this application, the float assembly 100 can be a large float, or the float assembly 100 can be a structure composed of multiple floats such as a first float 110 and a second float 120. When the float assembly 100 is a large float, the moving carrier 200 is disposed on one side of the float via sliding components such as slide rails, or the moving carrier 200 is embedded in the middle of the float via sliding components such as slide rails. When the float assembly 100 is a structure composed of multiple floats such as a first float 110 and a second float 120, the moving carrier 200 can be disposed between the multiple floats via sliding components such as slide rails and other structures. A float is a device that can float on water, generally including: a non-metallic float made of lightweight materials such as plastic or rubber, having good buoyancy and impact resistance; and a metallic float made of sealed metal, capable of floating on water.

[0046] The top of the mobile carrier 200 serves as a work surface, primarily for supporting maintenance personnel. In certain scenarios, it can also be used as an installation carrier, which may include, but is not limited to, movable plates; floats made of buoyancy materials or other floating structures; or other movable structures with load-bearing functions; no specific limitations are imposed here.

[0047] Optionally, the mobile carrier 200 is movably and switchably disposed on the float assembly 100 along a first direction a and / or a second direction b, where the second direction b intersects the first direction a. Specifically, the first direction a can be set to correspond to the width direction of the float assembly 100, the second direction b to correspond to the length direction of the float assembly 100, and the second direction b and the first direction a are perpendicular to each other. The mobile carrier 200 is movably and switchably disposed on the float assembly 100 at least between two positions along the second direction b, or the mobile carrier 200 is movably and switchably disposed on the float assembly 100 at least between two positions along the first direction a.

[0048] In related technologies, when the maintenance platform is locked to the current module pillar of a photovoltaic power station, the float is fixed. If maintenance personnel want to move to target modules on either side of the pillar, the maintenance platform needs to be released from the current pillar, and then locked back to the pillar corresponding to the target module after moving to its vicinity, resulting in inconvenience. In the embodiments of this application, when the maintenance platform is locked, if maintenance personnel want to move to target modules on either side of the pillar, they only need to adjust the moving carrier 200. By changing the position of the moving carrier 200 on the float assembly 100, the position of the moving carrier 200 relative to the photovoltaic power station can be adjusted accordingly, thus helping maintenance personnel move to the target module. Therefore, a secondary locking and releasing of the maintenance platform is unnecessary. Specifically, this application can also divide the photovoltaic power station into multiple inspection areas along its perimeter. The moving carrier 200 is movably switchable between at least two positions on the float assembly 100, allowing it to proceed to at least one of the multiple inspection areas of the photovoltaic power station for inspection when moved to different positions.

[0049] The position of the mobile carrier 200 is flexibly adjustable, allowing for adjustments and changes to its position on the float assembly 100 during adjustments, and correspondingly adjusting its position relative to the photovoltaic power station. Since the mobile carrier 200 carries maintenance personnel, its movable design increases the maintenance area of ​​the maintenance platform and facilitates flexible movement of personnel across the water surface. This not only improves maintenance efficiency and flexibility but also effectively addresses maintenance inconveniences, avoiding frequent startups of the maintenance platform and further reducing maintenance costs. The movable design of the mobile carrier 200 also helps the maintenance platform adapt to complex environmental requirements, enabling smooth maintenance work under various conditions.

[0050] Reference Figure 1Taking a float assembly 100 comprising multiple floats as an example, in one embodiment, the float assembly 100 includes a first float 110 and a second float 120 disposed opposite to each other along a first direction a; the structure, shape, size, etc. of the first float 110 and the second float 120 may be the same or different. When using a first float 110 and a second float 120 with the same structure, shape, size, etc., the first float 110 and the second float 120 may optionally be symmetrically disposed; when the float assembly 100 also includes other floats besides the first float 110 and the second float 120, the other floats may optionally be disposed at any directional position of the first float 110 and the second float 120, and the specific arrangement can be determined according to actual conditions, and is not limited here.

[0051] In this application, the first pontoon 110 and the second pontoon 120 are arranged opposite each other on the left and right sides along the first direction a; the mobile carrier 200 is slidably and switchably arranged between the first pontoon 110 and the second pontoon 120 along the second direction b, and the second direction b intersects with the first direction a.

[0052] As can be seen from the foregoing, when the first direction a corresponds to the width direction of the float assembly 100 and the second direction b corresponds to the length direction of the float assembly 100, the second direction b is perpendicular to the first direction a, and the moving carrier 200 can slide and switch between the first float 110 and the second float 120.

[0053] Specifically, it can be implemented using any one or more of the following methods:

[0054] As an example, the first pontoon 110 and the second pontoon 120 are connected together by a connecting plate 130 or other structure, and the first pontoon 110 and the second pontoon 120 are relatively fixed:

[0055] Optionally, either the first pontoon 110 or the second pontoon 120 may be fixed to the photovoltaic module's support column via a limiting part, positioning stake, or other limiting device, so that the maintenance platform is fixed to the support column corresponding to the current photovoltaic module; or, both the first pontoon 110 and the second pontoon 120 may be fixed to the photovoltaic module's support column via limiting parts, positioning stakes, or other limiting devices, so that the maintenance platform is fixed to the support column corresponding to the current photovoltaic module. A sliding component is provided between the mobile carrier 200 and at least one of the first pontoon 110 and the second pontoon 120. In this case, if it is necessary to move to the location of the target photovoltaic module, the first pontoon 110 and the second pontoon 120 remain stationary. By adjusting the position of the mobile carrier 200, the mobile carrier 200 can move relative to the first pontoon 110 and the second pontoon 120, further assisting maintenance personnel in moving to the location of the target photovoltaic module.

[0056] As another example, the first pontoon 110 and the second pontoon 120 are connected together by a connecting plate 130 or other structure, but the first pontoon 110 and the second pontoon 120 can move relative to each other:

[0057] Optionally, both the first pontoon 110 and the second pontoon 120 can be fixed to the photovoltaic module's support column via limiting parts, positioning stakes, or other limiting devices, so that the maintenance platform is fixed to the support column corresponding to the current photovoltaic module. A sliding component is provided between the mobile carrier 200 and at least one of the first pontoon 110 and the second pontoon 120. In this case, if it is necessary to move to the location of the target photovoltaic module, the first pontoon 110 and the second pontoon 120 remain stationary. By adjusting the position of the mobile carrier 200, the mobile carrier 200 can move relative to the first pontoon 110 and the second pontoon 120, further assisting maintenance personnel in moving to the location of the target photovoltaic module.

[0058] Alternatively, either the first float 110 or the second float 120 can be fixed to the photovoltaic module's support column via a limiting part, positioning stake, or other limiting device, so that the maintenance platform is fixed to the support column corresponding to the current photovoltaic module. Taking the case where the first float 110 is fixed to the photovoltaic module's support column, and a sliding component is provided between the moving carrier 200 and the first float 110 as an example: In this case, if it is necessary to move to the location of the target photovoltaic module, the first float 110 remains stationary. By adjusting the position of the moving carrier 200, the moving carrier 200 can move relative to the first float 110. If the moving carrier 200 and the second float 120 are connected together via a connector or connecting structure, adjusting the position of the moving carrier 200 will simultaneously move the second float 120. If the moving carrier 200 and the second float 120 are connected together via a slide rail or other sliding component, in addition to adjusting the moving carrier 200, the second float 120 can also be adjusted, allowing the second float 120 to move relative to the moving carrier 200. The embodiment in which the second float 120 is fixed to the column of the photovoltaic module can be referred to accordingly, and will not be repeated here.

[0059] This allows maintenance personnel to move flexibly over a wide area on the water surface along the length of the float assembly 100, enabling them to handle maintenance work over a larger area more flexibly.

[0060] Reference Figure 1 When the float assembly 100 includes a first float 110 and a second float 120, in order to ensure the stability of the overall structure, the float assembly 100 also includes a connecting plate 130, with the first float 110 and the second float 120 disposed on opposite sides of the connecting plate 130.

[0061] Understandably, the first pontoon 110 and the second pontoon 120 are disposed opposite each other on both sides of the connecting plate 130. Specifically, the connecting plate 130 can be a connecting structure used to firmly connect adjacent pontoons together, so as to form a stable floating platform together with the first pontoon 110, the second pontoon 120, etc., and further improve the stability and load-bearing capacity of the entire pontoon assembly 100. The connecting plate 130 has a first side and a second side disposed opposite each other along the first direction a, specifically implemented in any one or more of the following ways:

[0062] The first float 110 and the second float 120 are respectively connected to the first and second sides of the connecting plate 130; or, the first float 110 is connected to the first side of the connecting plate 130, and the second float 120 is connected between the first and second sides of the connecting plate 130; or, the second float 120 is connected to the second side of the connecting plate 130, and the first float 110 is connected between the first and second sides of the connecting plate 130; or, the first float 110 and the second float 120 are connected between the first and second sides of the connecting plate 130, wherein the first float 110 is positioned closer to the first side of the connecting plate 130, and the second float 120 is positioned closer to the second side of the connecting plate 130. When the float assembly 100 is placed in water, the first float 110 and the second float 120 are respectively subjected to the buoyancy of the water, and the connecting plate 130 is used to ensure that the float assembly 100 as a whole remains balanced and stable. When it is required that the maintenance and operation platform be fixed to the column corresponding to the current photovoltaic module, a limiting part, positioning stake or other limiting device can be set on one or both of the first float 110 and the second float 120, so that the maintenance and operation platform can be fixed to the column corresponding to the photovoltaic module by the limiting device set on the float; or, a limiting part, positioning stake or other limiting device can be set on the connecting plate 130, so that the maintenance and operation platform can be fixed to the column corresponding to the photovoltaic module by the limiting device set on the connecting plate 130.

[0063] Optionally, the connecting plate 130 is typically made of a robust and durable material and is located on the side of the float assembly 100 near the water surface (or, the connecting plate 130 is located on the lower surface of the float assembly 100). The movable carrier 200 is generally located on the upper surface of the connecting plate 130. The movable carrier 200 and the connecting plate 130 may not be directly connected, or the movable carrier 200 and the connecting plate 130 may be connected together by a sliding assembly.

[0064] Additionally, it should be noted that if the first pontoon 110 and the second pontoon 120 are structurally stable enough, and the mobile carrier 200 can still stably provide support for maintenance personnel when moving between different positions, the mobile carrier 200 can be used as a connecting structure to connect the first pontoon 110 and the second pontoon 120, without additionally setting the aforementioned connecting plate 130; the specific configuration can be determined according to actual conditions, and is not limited here.

[0065] The mobile carrier 200 is movably and switchably disposed on the float assembly 100 at least two positions. Optionally, the float assembly 100 has opposing front and rear ends along its length direction. Specifically, at least two positions can be provided along the length direction of the float assembly 100, including a first position and a second position. The first position is located near the front end of the float assembly 100, and the second position is located near the rear end of the float assembly 100. The mobile carrier 200 moves along the length direction of the float assembly 100. In addition, limiting structures for fixing the mobile carrier 200 can be provided at one or more positions, including the first position, the second position, and one or more positions between the first and second positions, for fixing the mobile carrier 200 between the first float 110 and the second float 120 by means of snapping, locking, or other methods when the mobile carrier 200 moves to the corresponding position.

[0066] In this application, a sliding component is provided between the float assembly 100 and the mobile carrier 200. When maintenance of the water surface photovoltaic power station is required, the float assembly 100 drives the maintenance platform to move to a position close to the photovoltaic power station. Maintenance personnel can then enter the photovoltaic power station through the maintenance platform to carry out maintenance work. When maintenance is required at other locations of the photovoltaic power station, the sliding component drives the mobile carrier 200 to move relative to the float assembly, thereby moving the maintenance personnel carried by the mobile carrier 200 to other locations of the photovoltaic power station.

[0067] Reference Figure 2 Specifically, a sliding assembly is provided between the mobile carrier 200 and the float assembly 100, allowing the mobile carrier 200 to move relative to the first float 110 and / or the second float 120 via the sliding assembly. This can be achieved using any one or more of the following methods:

[0068] As an example, a sliding assembly is provided between the mobile carrier 200 and the first pontoon 110, but no sliding assembly is provided between the mobile carrier 200 and the second pontoon 120, allowing the mobile carrier 200 to move relative to the first pontoon 110. If the mobile carrier 200 and the second pontoon 120 are not connected, the first pontoon 110 and the second pontoon 120 remain relatively stationary when the mobile carrier 200 moves; if the mobile carrier 200 and the second pontoon 120 are connected, the mobile carrier 200 drives the second pontoon 120 to move synchronously (i.e., the mobile carrier 200 and the second pontoon 120 slide relative to the first pontoon 110) when the mobile carrier 200 moves.

[0069] As another example, a sliding assembly is provided between the mobile carrier 200 and the second pontoon 120, but no sliding assembly is provided between the mobile carrier 200 and the first pontoon 110, allowing the mobile carrier 200 to move relative to the second pontoon 120. If the mobile carrier 200 and the first pontoon 110 are not connected, the second pontoon 120 and the first pontoon 110 remain relatively stationary when the mobile carrier 200 moves; if the mobile carrier 200 and the first pontoon 110 are connected, the mobile carrier 200 drives the first pontoon 110 to move synchronously when the mobile carrier 200 moves (i.e., the mobile carrier 200 and the first pontoon 110 slide relative to the second pontoon 120).

[0070] As another example, sliding components are provided between the mobile carrier 200 and the first pontoon 110, and between the mobile carrier 200 and the second pontoon 120, allowing the mobile carrier 200 to slide relative to the first pontoon 110 and the second pontoon 120. If the first pontoon 110 and the second pontoon 120 are connected together and relatively fixed by a connecting structure such as a connecting plate 130, then when the mobile carrier 200 moves, the first pontoon 110 and the second pontoon 120 remain stationary; if the first pontoon 110 and the second pontoon 120 can move relative to each other, then when the mobile carrier 200 moves, the one of the first pontoons 110 and the second pontoon 120 that is not fixed to the column can move relative to the one that is fixed to the column.

[0071] As another example, a sliding assembly is provided between the mobile carrier 200 and the connecting plate 130. The connecting plate 130 connects the first pontoon 110 and the second pontoon 120. The first pontoon 110 and the second pontoon 120 are connected together and relatively fixed through the connecting plate 130. The mobile carrier 200 can move relative to the first pontoon 110 and the second pontoon 120. When the mobile carrier 200 moves, the first pontoon 110 and the second pontoon 120 are relatively stationary.

[0072] In this application, the sliding assembly includes a first sliding member 310 and a second sliding member 320. One of the first sliding member 310 and the second sliding member 320 is a slide rail, and the other is a slider that is slidably adapted to the slide rail. The slider is slidably mounted on the slide rail and moves back and forth along the slide rail. The sliding of the slider along the slide rail will drive the moving carrier 200 to move together, thereby realizing the displacement of the moving carrier 200 relative to the float assembly 100.

[0073] When the moving carrier 200 needs to be moved, it can be manually pushed or pulled to make the slider slide along the slide rail; or, the slider can be pushed or pulled by a drive device (such as a motor, hydraulic cylinder, etc.) to make the slider slide along the slide rail as an electric slider. When power is provided by a drive device, corresponding control circuits (such as sensors, controllers, etc.) may be required to precisely control the position and speed of the moving carrier 200. The sliding component itself may have power (i.e., the sliding component includes a drive device) or may not have power (i.e., a separate drive device is required), depending on the actual setup, and is not limited here.

[0074] Reference Figure 1 , Figure 2 Based on the aforementioned embodiments, when a sliding assembly is provided between the mobile carrier 200 and the first float 110 (and / or the second float 120), the mobile carrier 200 is provided with a first sliding member 310, and the first float 110 (and / or the second float 120) is provided with a second sliding member 320.

[0075] When a sliding assembly is provided between the mobile carrier 200 and the connecting plate 130, the mobile carrier 200 is provided with a first sliding member 310 and the connecting plate 130 is provided with a second sliding member 320.

[0076] The sliding component serves as a connection, support, and guide. The slider and the slide rail are slidably adapted. As the slider slides along the slide rail, the relative position between the float assembly 100 and the moving carrier 200 can be changed by adjusting the relative position between the slide rails. The sliding adaptation between the slider and the slide rail also reduces friction, allowing the moving carrier 200 and the float assembly 100 to slide smoothly relative to each other, thereby improving motion efficiency and accuracy. The overall structure is simple and easy to assemble.

[0077] Optionally, in the embodiments of this application, the sliding component can be, but is not limited to, any one or a combination of other structures as described below: the guide rail is configured as a long strip, the slider is configured as an annular slider, and the slider is sleeved on the guide rail to achieve a sliding connection; the surface of the guide rail is designed with continuous grooves (or tracks), and the slider is designed with protrusions (or convex rails) that are adapted to the grooves (or tracks) of the guide rail, which can be precisely embedded in the grooves (or tracks) of the guide rail to achieve a sliding connection; the slider has grooves, and the guide rail has protrusions that are adapted to the grooves of the slider, which can be precisely embedded in the grooves of the slider to achieve a sliding connection; rolling elements (such as balls, rollers, etc.) are designed between the guide rail and the slider. These rolling elements are located between the contact positions of the guide rail and the slider and are usually installed in a retainer. When the slider slides along the guide rail, the balls will roll between the guide rail and the slider to achieve a sliding connection and reduce friction and wear through rolling; the specific configuration can be determined according to actual conditions and is not limited here.

[0078] Reference Figure 1 Based on the aforementioned embodiment, the mobile carrier 200 is movable relative to the first float 110 and the second float 120. To improve stability, a handrail 440 is installed on the mobile carrier 200; specifically, the handrail 440 is installed on the upper surface of the mobile carrier 200. When the mobile carrier 200 is moved by an electric slider, maintenance personnel can hold the handrail 440 to ensure balance during movement.

[0079] In addition, without limiting this application, a handrail 440 may be provided on the side of the first pontoon 110 near the mobile carrier 200 (and / or on the side of the second pontoon 120 near the mobile carrier 200). The specific arrangement can be determined according to the actual situation and is not limited here.

[0080] Taking the float assembly 100 as an example, which uses a large float, a sliding assembly is provided between the float assembly 100 and the moving carrier 200. Specifically, a slide rail can be provided in the middle of the float, and a slider adapted to slide along the slide rail can be provided at the bottom and / or periphery of the moving carrier 200; or, a slide rail can be provided at the bottom and / or periphery of the moving carrier 200, and a slider adapted to slide along the slide rail can be provided in the middle of the float. The specific implementation method can refer to the aforementioned embodiment of providing a sliding assembly between the moving carrier 200 and the first float 110 (and / or the second float 120), which will not be described in detail here.

[0081] In the technical solution of this application, in order to simplify the structure of the maintenance and operation platform and further expand the application scenarios of the maintenance and operation platform, the maintenance and operation platform may include, but is not limited to, structures such as guardrail 410 and ladder 420, and the aforementioned structures may be further set on the float assembly 100 and / or the mobile carrier 200.

[0082] Reference Figure 1 In one embodiment, when the maintenance platform also includes multiple guardrails 410, they can be used to provide safety protection for maintenance personnel during the movement of the maintenance platform.

[0083] Specifically, in the technical solution of this application, multiple guardrails 410 are arranged around at least a portion of the mobile carrier 200 on the pontoon assembly 100. Specifically, guardrails 410 can be respectively arranged on the first pontoon 110 and the second pontoon 120, and the guardrails 410 are arranged around at least one side of the pontoon assembly 100. The arrangement of guardrails 410 can improve the safety of the maintenance platform, provide support for maintenance personnel, and effectively isolate maintenance personnel from the water area, reducing the risk of falling into the water. The guardrails 410 also play a certain buffering role, preventing impact on the pontoon assembly 100 when approaching photovoltaic power stations or ships and other water equipment, thereby extending the service life of the pontoons.

[0084] Reference Figure 1 , Figure 3 , Figure 4 For photovoltaic power plants, regular inspections and maintenance are essential. When the maintenance platform includes a ladder 420, it helps maintenance personnel leave the platform and access the shore. The ladder 420 is rotatably mounted on the float assembly 100, and its opening angle is adjusted accordingly during rotation. The design of the ladder 420 allows maintenance personnel to more easily reach higher parts of the photovoltaic power plant to perform necessary inspections, repairs, and maintenance. The rotatable structure of the ladder 420 facilitates storage and installation, and also allows for easy adjustment of the opening angle.

[0085] Specifically, a first mounting groove 140 for mounting the ladder 420 can be provided on the upper surface of the first float 110 and / or the second float 120. Furthermore, the maintenance platform also includes a rotating base 421, which is connected to the mobile carrier 200 and is used to drive the ladder 420 to rotate.

[0086] Optionally, the rotating seat 421 is specifically disposed in the first mounting groove 140. The rotating seat 421 is provided with a hinge structure (such as a rotary hinge, universal hinge, etc.), and the rotating seat 421 is hinged to the first mounting groove 140 via the hinge structure. In related technologies, although ladders are provided on the maintenance platform, maintenance personnel need to find support points on the pontoon for support when in use, which is inconvenient to use, unsafe to use, and inconvenient to store. In the embodiment of this application, when the ladder 420 is stored in the first mounting groove 140 and the ladder is needed (such as when maintenance personnel need to leave the maintenance platform and go ashore), the ladder 420 is rotated in a way that it rotates towards the shore or other destination, which opens the ladder 420. The rotating seat disposed in the first mounting groove 140 provides support for the ladder 420, without the need to find additional support points, effectively improving safety and convenience of use. When the ladder 420 is in the open state and needs to be stored, it is stored by rotating towards the first mounting slot 140, effectively solving the problem of inconvenient storage. This application uses a rotating base 421 to rotate the ladder 420 stored in the first mounting slot 140, and the ladder 420 is stored through the first mounting slot 140. Specifically, when maintenance personnel need to go ashore, since the shore position is not fixed, the rotating base 421 is used to rotate the ladder 420 to adjust its opening angle. Using the side of the ladder 420 away from the first mounting slot 140 as the ladder surface, when maintenance personnel need to leave the maintenance platform and go ashore, they pull the ladder 420 with the ladder surface facing the shore, causing the rotating base 421 to rotate the ladder 420 until the end of the ladder 420 away from the rotating base 421 rests on the shore, thus facilitating the maintenance personnel's access ashore. When maintenance personnel do not need to use the ladder in daily operations or when they need to retract the ladder 420 back into the first mounting slot 140, they can rotate the ladder 420 toward the first mounting slot 140 to retract the ladder 420 back into the first mounting slot 140.

[0087] Reference Figure 4In some specific embodiments of this application, the rotating seat 421 is provided with locking structures such as locking pin 422. Taking locking pin 422 as an example, locking pin 422 is used to realize the locking function and is specifically used to fix the rotating seat 421 inside the first mounting groove 140 to prevent the rotating seat 421 from moving. Specifically, the locking pin 422 passes through the rotating seat 421 and is connected to the first mounting groove 140 by means of threaded connection, snap-fit, etc. The locking pin 422 is used to limit the rotating seat 421. When the locking pin 422 is connected to the first mounting groove 140, and specifically when the ladder 420 needs to be retracted into the first mounting groove 140, the locking pin 422 is used to connect and fix the rotating seat 421 to the first mounting groove 140, so that the rotating seat 421 cannot rotate by limiting the rotating seat 421. When the locking pin 422 is not connected to the first mounting groove 140 (or does not completely pass through the rotating seat 421), and specifically when the maintenance personnel need to leave the maintenance platform, the locking pin 422 is used to release the restriction on the rotating seat 421, so that the rotating seat 421 can rotate, and thus drive the ladder 420 to rotate.

[0088] In other embodiments of this application, it is not excluded that the hinge structure corresponding to the rotating seat 421 is provided with a locking structure such as a locking pin 422. The locking structure is used to limit the rotating seat 421 when it is engaged with the hinge structure, and to release the restriction on the rotating seat 421 when the connection with the hinge structure is released.

[0089] When maintenance personnel approach the photovoltaic power station, to ensure the safe parking and stability of the maintenance platform, it needs to be secured to one side of the photovoltaic power station.

[0090] Reference Figure 1 , Figure 5 In one embodiment, the photovoltaic power station includes a column, and a limiting part 450 is provided on the periphery of the float assembly 100. A limiting space 451 is formed in the middle of the limiting part 450 for restraining or locking the column. The limiting part 450 on the periphery of the float assembly 100 not only restrains the column but also enables the safe docking of the maintenance platform. This ensures that the maintenance platform remains stably in a fixed position during docking, facilitating maintenance personnel to perform maintenance, upkeep, or other operations on the photovoltaic power station. It also prevents the maintenance platform from drifting and colliding with other facilities, thus improving safety.

[0091] Reference Figure 5 Specifically, the limiting part 450 includes a first fixing rod 452, a second fixing rod 453 and a connecting pin 454. The first fixing rod 452 and the second fixing rod 453 are connected to the float, and the connecting pin 454 is connected between the first fixing rod 452 and the second fixing rod 453. The connecting pin 454 can be detachably connected to the first fixing rod 452 and the second fixing rod 453 by means of threaded connection, snap-fit, fastening, magnetic attraction and other methods.

[0092] The limiting space 451 is used to restrict the space in which the maintenance platform can move relative to the photovoltaic power station's support column. In this application, the limiting space 451 is formed between the first fixed rod 452, the connecting pin 454, the second fixed rod 453, and the float. When maintenance personnel approach the photovoltaic power station, they remove the connecting pin 454 from between the first fixed rod 452 and the second fixed rod 453, move the two fixed rods to both sides of the photovoltaic power station's support column, and then connect and fix the connecting pin 454 between the first fixed rod 452 and the second fixed rod 453. This restricts the photovoltaic power station's support column within the limiting space 451 formed by the first fixed rod 452, the connecting pin 454, the second fixed rod 453, and the float, thereby fixing the maintenance platform to one side of the photovoltaic power station, completing the docking, and preventing the maintenance platform from shifting position or even being lost.

[0093] In addition, in other embodiments of this application, it is not excluded that the limiting part 450 is configured as a limiting buckle or other limiting structure, so that the limiting space 451 is formed in the limiting hole in the middle of the limiting buckle or other positions, which is not limited here.

[0094] Taking floating photovoltaic power stations as an example, these types of photovoltaic power stations include multiple floating bodies such as pontoons. Photovoltaic modules are connected and fixed through floating bodies. Sometimes there is no suitable passage between floating bodies, and maintenance personnel face difficulties and inconvenience when they need to work across floating bodies.

[0095] Reference Figure 1 In one embodiment, when the maintenance platform further includes a footrest 430, the mobile carrier 200 is provided with an installation slot for the footrest 430 to be detachably installed; this installation slot is defined as a second installation slot 210, and the footrest 430 is detachably installed in the second installation slot 210. When maintenance personnel enter the photovoltaic power station and need to work across the floating bodies, the footrest 430 can be removed from the second installation slot 210 and placed between the floating bodies of the photovoltaic power station. The footrest 430, as a connecting bridge between the floating bodies, can provide support for maintenance personnel to work across the floating bodies, facilitating their operations.

[0096] Since the handrail 440 used to help maintenance personnel maintain balance during movement is provided on the mobile carrier 200, the aforementioned handrail 440 and pedal 430 can be provided at different positions on the mobile carrier 200, or, in order to save space, the aforementioned handrail 440 can be provided close to the second mounting slot 210.

[0097] Reference Figures 1 to 5 The specific implementation plan of this application is as follows:

[0098] The maintenance and repair platform for photovoltaic power plants includes a float assembly 100 and a mobile carrier 200. The mobile carrier 200 is movably switchable between at least two positions on the float assembly 100. The float assembly 100 includes a first float 110, a second float 120, and a connecting plate 130. The connecting plate 130 is located on the side of the float assembly 100 closest to the water surface (or on the lower surface of the float assembly 100). The first float 110 and the second float 120 are located opposite each other on both sides of the connecting plate 130. The mobile carrier 200 is located on the upper surface of the connecting plate 130. When a sliding assembly is provided between the mobile carrier 200 and the connecting plate 130, the mobile carrier 200 is provided with a slide rail, and the connecting plate 130 is provided with a slider that is adapted to slide along the slide rail. The slider is pushed or pulled by an external drive device (such as a motor, hydraulic cylinder, etc.), causing the slider to slide along the slide rail as an electric slider.

[0099] When maintenance is required at a photovoltaic power station, the maintenance platform is moved to the photovoltaic power station by the floating assembly 100, allowing maintenance personnel to enter the photovoltaic power station for repairs.

[0100] When maintenance is required at other locations within the photovoltaic power station, the mobile carrier 200 is moved along the slide rail by an electric slider, thereby relocating the maintenance personnel to other locations within the photovoltaic power station. Guardrails 410 are fixedly installed on the upper surfaces of both the first pontoon 110 and the second pontoon 120, providing safety protection for maintenance personnel during the movement of the maintenance platform.

[0101] A handrail 440 is fixedly installed on the upper surface of the mobile carrier 200. When the mobile carrier 200 moves, maintenance personnel can hold the handrail 440 to maintain balance while moving through the mobile carrier 200.

[0102] The upper surface of the first buoy 110 and / or the second buoy 120 is provided with a first mounting groove 140 for mounting the ladder 420. A rotating seat 421 is rotatably connected inside the first mounting groove 140, and the ladder 420 is hinged to the upper surface of the rotating seat 421. The rotating seat 421 is provided with a locking pin 422, which passes through the rotating seat 421 and is connected to the first mounting groove 140 by a threaded connection. When maintenance personnel need to leave the maintenance platform, the locking pin 422 is not connected to the first mounting groove 140, and the restriction on the rotating seat 421 is released, allowing the rotating seat 421 to rotate. When the ladder 420 is stored in the first mounting groove 140 and the ladder needs to be used (e.g., when maintenance personnel need to leave the maintenance platform), since the landing position is not fixed, the rotating seat 421 is used to rotate the ladder 420 to adjust the opening angle of the ladder 420. Using the side of ladder 420 furthest from the first mounting slot 140 as the ladder surface, when maintenance personnel need to leave the maintenance platform and go ashore, they pull ladder 420 with the ladder surface facing the shore, causing the rotating seat 421 to rotate ladder 420 until the end of ladder 420 furthest from the rotating seat 421 rests on the shore, facilitating the maintenance personnel's ascent. When maintenance personnel do not need to use the ladder regularly or need to retract ladder 420 back into the first mounting slot 140, they rotate ladder 420 with the ladder facing the first mounting slot 140 to retract ladder 420 back into the first mounting slot 140. Locking pin 422 connects to the first mounting slot 140 and is used to limit the rotation seat 421.

[0103] The mobile carrier 200 has a second mounting slot 210 on its upper surface, and a footrest 430 is installed inside the second mounting slot 210. When maintenance personnel enter the photovoltaic power station and need to work across the floating bodies, they can remove the footrest 430 from the second mounting slot 210 and place it between the floating bodies of the photovoltaic power station. The footrest 430 acts as a connecting bridge between the floating bodies, providing support for maintenance personnel to work across the floating bodies and facilitating their operations.

[0104] A limiting part 450 is fixedly installed on one side of the outer wall of the float assembly 100. The limiting part 450 includes a first fixing rod 452, a second fixing rod 453, and a connecting pin 454. The first fixing rod 452 and the second fixing rod 453 are connected to the float assembly 100, and the connecting pin 454 is connected between the first fixing rod 452 and the second fixing rod 453. When maintenance personnel approach the photovoltaic power station, they remove the connecting pin 454 from between the first fixing rod 452 and the second fixing rod 453, move the two fixing rods to both sides of the photovoltaic power station's column, and then connect and fix the connecting pin 454 between the first fixing rod 452 and the second fixing rod 453. This restricts the photovoltaic power station's column within the limiting space 451 formed by the first fixing rod 452, the connecting pin 454, the second fixing rod 453, and the float, thereby fixing the maintenance platform to one side of the photovoltaic power station and completing the docking.
