Description

Technical Field

[0001] This utility model relates to the field of surface photovoltaic equipment technology, and in particular to a mobile maintenance mechanism and a marine photovoltaic platform. Background Technology

[0002] The ocean provides a favorable environment for photovoltaic power generation due to its unobstructed and vast area. However, to reduce the drift of surface photovoltaic platforms, it is usually necessary to set up large-area photovoltaic platforms and cover them with photovoltaic modules to improve power generation efficiency. However, the maintenance and operation of the marine environment are complex. After the photovoltaic system has been running on the water for a long time, it is necessary to clean, repair and replace some photovoltaic modules. Since the area inside the platform is covered with photovoltaic modules, maintenance personnel have to step on the photovoltaic modules to reach the target location. This not only makes the maintenance process complicated, but also poses a risk of damaging the photovoltaic modules during the maintenance process, thus increasing the power generation cost of surface photovoltaic modules.

[0003] Therefore, how to reduce the maintenance difficulty and damage risk of photovoltaic modules on offshore photovoltaic platforms is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a mobile maintenance mechanism to reduce the maintenance difficulty and damage risk of photovoltaic modules on a marine photovoltaic platform.

[0005] Another objective of this invention is to provide a marine photovoltaic platform that includes the aforementioned mobile maintenance mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides a mobile maintenance mechanism for providing a path to any location on a target platform, comprising:

[0008] A fixed staircase is arranged around the edge of the target platform to form a closed passageway structure;

[0009] The movable escalator is slidably configured relative to the fixed escalator. The movable escalator is capable of reciprocating in a first direction, and the sliding sweep area of ​​the movable escalator along the positive or negative direction of the first direction covers the closed area of ​​the fixed escalator.

[0010] Preferably, the mobile maintenance mechanism further includes a guide rail, the guide rail being guided along the first direction; the mobile ladder includes a plurality of sets of rollers arranged along its length, the rollers being slidably engaged with the guide rail.

[0011] Preferably, in the above-mentioned mobile maintenance mechanism, the guide rail is fixedly mounted on the mounting profile of the target platform.

[0012] Preferably, in the above-mentioned mobile maintenance mechanism, at least three sets of guide rails are provided along the second direction, and at least one set of guide rails is located at the middle position of the target platform in the second direction; the second direction is perpendicular to the first direction.

[0013] Preferably, in the above-mentioned mobile maintenance mechanism, the mobile ladder further includes several blocking bars, which are arranged in a vertical direction and abut against or are higher than the upper surface of the mounting profile.

[0014] Preferably, the mobile maintenance mechanism further includes a drive unit, which is connected to the mobile elevator and drives the mobile elevator to slide in the positive and negative directions of the first direction.

[0015] Preferably, in the above-mentioned mobile maintenance mechanism, the fixed ladder has a rectangular configuration, the length of the first side of the mobile ladder is equal to that of the fixed ladder, the sliding path of the mobile ladder covers the second side of the fixed ladder, and the first side and the second side are adjacent.

[0016] Preferably, in the above-mentioned mobile maintenance mechanism, the fixed escalator is set based on the extension of the target platform, and the two ends of the mobile escalator are intersected and connected to the two second sides of the fixed escalator.

[0017] Preferably, in the above-mentioned mobile maintenance mechanism, the fixed ladder is circular, the length of the mobile ladder is not less than the diameter of the fixed ladder, and the sliding path of the mobile ladder covers the diameter of the fixed ladder in the direction perpendicular to the mobile ladder.

[0018] Secondly, this utility model provides a marine photovoltaic platform, which includes multiple photovoltaic modules and a mobile maintenance mechanism as described in any of the above.

[0019] As can be seen from the above technical solution, the mobile maintenance mechanism provided in this disclosure has fixed ladders arranged around the edge of the target platform, and the fixed ladders form a closed passage structure. During the inspection and maintenance of photovoltaic modules at the edge of the target platform, operators can directly reach the target position on the fixed ladders and perform the inspection and maintenance operations. At the same time, the mobile maintenance mechanism is equipped with a mobile ladder, which is a structure that slides relative to the fixed ladder. The sliding direction of the mobile ladder is a reciprocating sliding in a first direction to achieve position adjustment, and the mobile ladder sweeps across the area along the positive or negative direction of the first direction. When a target location within the target platform requires maintenance, the mobile elevator can slide in the first direction to directly above the target location, covering the closed area of ​​the fixed elevator. Operators can then use the mobile elevator to move directly above the target location and reach the target platform for subsequent maintenance. This process does not require contact with the photovoltaic modules on the target platform, thus reducing the risk of damage to the photovoltaic modules and the difficulty of maintenance movement for operators. At the same time, when maintenance is not required, the mobile elevator can also slide to avoid the photovoltaic modules on the target platform, thus preventing shading and affecting the power generation efficiency of the photovoltaic modules.

[0030] The core of this utility model lies in disclosing a mobile maintenance mechanism to reduce the maintenance difficulty and damage risk of photovoltaic modules on a marine photovoltaic platform.

[0031] Another objective of this invention is to provide a marine photovoltaic platform that includes the aforementioned mobile maintenance mechanism.

[0032] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0033] like Figures 1-7 As shown, the mobile maintenance mechanism provided in this embodiment of the present disclosure is used to provide a path for personnel to reach any location on the target platform 40 and avoid trampling on the photovoltaic modules 420 on the target platform 40.

[0034] Specifically, the mobile maintenance mechanism mainly includes a fixed escalator 10 and a mobile escalator 20, both of which are stepped passage structures that allow at least one person to pass through smoothly. The fixed escalator 10 is located at the edge of the target platform 40, specifically surrounding the edge of the target platform 40 and forming a closed passage structure. This allows operators to directly reach the target location and perform maintenance operations by moving along the fixed escalator 10 when inspecting and maintaining the photovoltaic modules 420 located at the edge of the target platform 40.

[0035] Based on the above structure, the mobile escalator 20 is slidably set relative to the fixed escalator 10, which can change its position relative to the target platform 40. The mobile escalator 20 can slide back and forth in the first direction to achieve position adjustment. It should be noted that the unidirectional reciprocating sliding structure is simple and easy to assemble, and the risk of structural failure can be reduced by simplifying the sliding structure.

[0036] Simultaneously, the sliding sweep area of ​​the mobile escalator 20 along the first direction, either positively or negatively, covers the closed area of ​​the fixed escalator 10. It should be noted that the sliding sweep area specifically refers to the area of ​​a quadrilateral formed by the length of the mobile escalator 20 as one side and the maximum movement path of the mobile escalator 20 along the first direction being the area of ​​the other adjacent side. The fact that the sliding sweep area of ​​the mobile escalator 20 along the first direction covers the closed area of ​​the fixed escalator 10 allows the mobile escalator 20 to pass through the closed area of ​​the fixed escalator 10 along its movement path, i.e., directly above any position on the target platform 40. Based on this, when there is a maintenance requirement at a target location inside the target platform 40, the position of the mobile escalator 20 in the first direction can be adjusted so that the mobile escalator 20 is directly above the target location. Operators can then use the mobile escalator 20 to move to directly above the target location and reach the target platform 40 for subsequent maintenance, reducing the risk of damage to the photovoltaic modules 420 and the difficulty of operators moving to the target platform 40 for maintenance.

[0037] It should be noted that, in some embodiments, when the mobile elevator 20 is used to reach the middle area of ​​the target platform 40, the operator can move from the fixed elevator 10 to the position where the mobile elevator 20 intersects after the mobile elevator 20 has moved, and reach the target position by moving on the mobile elevator 20; while in other embodiments, the operator can also directly board the mobile elevator 20 at a convenient location and move with the mobile elevator 20 to the middle area of ​​the target platform 40.

[0038] Furthermore, it should be noted that in the mobile maintenance mechanism provided in this embodiment, when no maintenance is required, the mobile ladder 20 can also slide to avoid the photovoltaic module 420 on the target platform 40, thereby avoiding shading and affecting the power generation efficiency of the photovoltaic module 420.

[0039] Furthermore, the stable sliding of the mobile elevator 20 in the first direction is the basis for providing a path to any position on the target platform 40. The mobile elevator 20 can achieve a sliding structure through methods such as planar docking sliding and wheel system sliding. In some embodiments, the mobile elevator 20 adopts a wheel system sliding structure to achieve relative sliding with the fixed elevator 10. Specifically, the mobile elevator 20 includes several sets of rollers 210 arranged along its length to improve the running stability of the mobile elevator 20 by having low sliding friction. At the same time, since the rollers 210 will have large pressure due to the small contact surface, in order to avoid damage to the sliding structure of the mobile elevator 20, the mobile maintenance mechanism also includes a guide rail 30 with the guide direction along the first direction, and the rollers 210 slide with the guide rail 30 to achieve reciprocating movement in the first direction.

[0040] It should be noted that the slide rail can be fixedly installed on one side of the fixed escalator 10 or fixedly installed on the target platform 40, both of which can meet the requirement of providing a stable sliding path for the mobile escalator 20. Considering that the fixed escalator 10 has lower strength than the target platform 40, and the target platform 40 has a larger load-bearing foundation and installation space, in some embodiments of this disclosure, the guide rail 30 is fixedly installed on the target platform 40. In order to provide sufficient load-bearing strength, the target platform 40 is provided with mounting profiles 410 for the guide rail 30 to be assembled, and provides sufficient support foundation for the guide rail 30 and the mobile escalator 20.

[0041] Furthermore, it should be noted that the sliding process of the mobile elevator 20 can be achieved by manual pushing by the operator or by automatic drive. In order to reduce the difficulty of operation, in some embodiments of this disclosure, the mobile maintenance mechanism also includes a drive unit, which can be a motor, cylinder or motor, and is connected to the mobile elevator 20 for transmission, and has at least a forward and reverse drive mode, so as to drive the mobile elevator 20 to slide in the forward and negative directions of the first direction, thereby reducing the difficulty of the operator to inspect and maintain the photovoltaic module 420 on the target platform 40.

[0042] Furthermore, in the mobile maintenance mechanism provided in this embodiment, in order to ensure the stable operation of the mobile elevator 20, at least three sets of guide rails 30 are arranged at intervals along the second direction, and each set of guide rails 30 is equipped with rollers 210. That is, for the mobile elevator 20, it has at least three support positions in the second direction to reduce the risk of tilting and improve the stability of the sliding process.

[0043] It should be noted that the second direction is preferably perpendicular to the first direction. In some embodiments, the second direction is the length direction of the moving elevator 20.

[0044] Furthermore, at least one set of guide rails 30 is located in the middle of the target platform 40 in the second direction, and preferably two sets of guide rails 30 are arranged on both sides of the target platform 40 in the second direction, and are symmetrically arranged about the guide rail 30 located in the middle of the target platform 40, so that the moving elevator 20 in the upper region of the target platform 40 has uniform support points on the target platform 40, thereby improving the support strength of the target platform 40 for the moving elevator 20 and reducing the risk of the moving elevator 20 falling off.

[0045] To further enhance the operational safety of the mobile maintenance mechanism, in some embodiments of this disclosure, the mobile ladder 20 also includes a blocking bar 220. Several blocking bars 220 are provided and arranged on the same plane, and preferably at least two blocking bars 220 are provided as backups for each other. The blocking bars 220 abut against the upper surface of the mounting profile 410 on the target platform 40 in the vertical direction, or are higher than the upper surface of the mounting profile 410. When the mobile ladder 20 is at risk of falling off due to damage or abnormal operation of the rollers 210, the blocking bars 220 can directly support the mobile ladder 20 by abutting against the upper surface of the mounting profile 410, and prevent the mobile ladder 20 from falling off further, thus avoiding safety accidents. It can also protect the photovoltaic modules 420 on the target platform 40 and reduce the risk of economic loss.

[0046] Furthermore, in the mobile maintenance mechanism provided in the embodiments of this disclosure, the fixed ladder 10 needs to be arranged around the edge of the target platform 40 to form a closed passage structure. Its external structure can be larger than the target platform 40, or the same as the target platform 40, only needing to cover the effective installation area of ​​the photovoltaic modules 420 of the target platform 40. In some embodiments of this disclosure, the fixed ladder 10 is rectangular in shape, which is suitable for the rectangular target platform 40. Specifically, the rectangular fixed ladder 10 includes adjacent first and second sides to form the length and width of the rectangle, while the movable ladder 20 has the same length as the first side of the fixed ladder 10, and the two ends of the movable ladder 20 are connected to the two second sides of the fixed ladder 10. The sliding path of the movable ladder 20 in the first direction covers the second side of the fixed ladder 10, so that the movable ladder 20 can cover the target platform 40 and meet the movement requirements to reach any position on the target platform 40.

[0047] Based on the above embodiments, the fixed elevator 10 is set on the outer extension of the target platform 40 so as not to occupy the space of the target platform 40 and improve the space utilization rate on the target platform 40.

[0048] In other embodiments of this disclosure, the fixed ladder 10 is circular in shape, which is suitable for the circular target platform 40 to achieve a surrounding arrangement of the target platform 40. Correspondingly, the length of the movable ladder 20 is not less than the diameter of the fixed ladder 10 to ensure that the movable ladder 20 can cross the fixed ladder 10. In the direction perpendicular to the movable ladder 20, the sliding path of the movable ladder 20 covers the diameter of the fixed ladder 10, so that the rectangular area of ​​the sliding operation of the movable ladder 20 can cover the circular fixed ladder 10, and realize the movement requirement to reach any position on the target platform 40.

[0049] Furthermore, this disclosure also provides a marine photovoltaic platform, on which multiple photovoltaic modules 420 are mounted on top. The platform also includes a mobile maintenance mechanism as described in any of the above embodiments, providing a movement path for the photovoltaic modules 420 at any location to achieve maintenance and repair. It should be noted that since this mobile maintenance mechanism possesses the technical effects provided in any of the above embodiments, the marine photovoltaic platform also possesses the technical effects provided in any of the above embodiments, and will not be elaborated upon further here.
