Description

Technical Field

[0001] This invention relates to the field of snow removal technology for photovoltaic panels, specifically a snow removal device for marine photovoltaic panels. Background Technology

[0002] Offshore photovoltaic panels, also known as offshore photovoltaic power generation systems, refer to facilities that install photovoltaic modules (solar panels) in marine waters (including nearshore areas, tidal flats, bays, etc.) to generate electricity using solar energy. Offshore photovoltaic panels are mainly divided into pile-fixed type and floating type.

[0003] When offshore photovoltaic panels are in use, snow accumulation on the surface of the panels will directly block sunlight, resulting in a significant reduction in power generation efficiency. At the same time, snow and ice will increase the load on the floating platform, which may cause unbalanced load and the risk of overturning. In addition, the windy and snowy environment at sea will increase the risk of wind load and structural damage. Therefore, it is necessary to use snow removal equipment to remove snow from the offshore photovoltaic panels in a timely manner to ensure power generation efficiency, platform operation safety and equipment lifespan.

[0004] Snow removal robots, as a type of snow removal device for offshore photovoltaic panels, are used for snow removal operations on floating photovoltaic platforms at sea (as per the instruction manual). Figure 10 As shown in the diagram, the robot moves on the surface of the photovoltaic panel via a tracked chassis. A pusher plate on the front of the tracked chassis pushes the panel to remove snow. However, due to the uneven snow accumulation on the photovoltaic panel surface, there is a deviation in snow accumulation on both sides of the pusher plate during the snow removal process. This results in asymmetrical snow-pushing resistance and generates lateral torque. In situations where the floating photovoltaic platform sways with the waves and the panel surface is slippery with ice and snow, this lateral torque, combined with the platform's swaying tendency, can easily cause the robot to tip over or fall. Furthermore, the torque deviation on both sides of the pusher plate can cause deformation and jamming, severely hindering normal snow removal operations. Therefore, we propose a snow removal device for offshore photovoltaic panels. Summary of the Invention

The lifting assembly, mounted on the tracked chassis, is used to assist in the lifting and adjustment of the snow removal assembly. And a transmission component set between the two sets of push plates to drive the push plates when the two sets of push plates push snow at different times.

[0007] Preferably, the transmission assembly includes a connecting plate disposed between two sets of push plates. The connecting plate and the push plates are matched in shape.

[0008] Preferably, the mounting assembly includes a mounting plate fixed to the front side of the connecting plate, and an iron block and a magnetic block for magnetic fixation are respectively fixed on the side of the mounting plate opposite to the first plate body.

[0011] Preferably, the telescopic assembly includes multiple sets of sleeves fixed on the L-shaped frame, with a sliding rod slidably connected to each sleeve.

During the snow removal process, the coordinated operation of the telescopic component, sliding component, and transmission component allows for the reduction of the snow removal length and resistance on one side when snow removal is uneven. This quickly balances the snow removal resistance on both sides of the pusher, reducing the lateral overturning moment caused by the asymmetry in resistance between the two sides. This prevents the snow removal robot from veering off course, tilting, or getting stuck when performing snow removal operations on floating photovoltaic platforms, ensuring normal snow removal operations.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0019] Please see Figures 1-10 The snow removal device for marine photovoltaic panels shown in the figure includes a snow removal robot for walking and removing snow on the surface of marine photovoltaic panels. The snow removal robot includes a tracked chassis 1, which has a front side and a rear side arranged according to the direction of travel. It should be noted here that the tracked chassis 1 is a conventional component, and its structural composition, operating principle and control method are known technologies in this application, and will not be described in detail here. It also includes a snow removal component, which is set on the front side of the tracked chassis 1 and is used to push snow removal from the surface of the marine photovoltaic panel. The snow removal component includes two sets of push plates 202 symmetrically arranged on the front side of the tracked chassis 1. An L-shaped frame 201 for auxiliary connection is provided between the push plates 202 and the tracked chassis 1. The push plate 202 is composed of a first plate 2021 and a second plate 2023. A groove 2022 is provided on the first plate 2021. A sliding component for assisting the sliding connection of the second plate 2023 is provided between the groove 2022 and the second plate 2023. The length of the push plate 202 is adjusted by the telescopic sliding of the second plate 2023 on the groove 2022. A telescopic component for assisting the telescopic connection is provided between the first plate 2021 and the L-shaped frame 201. A lifting assembly, mounted on the tracked chassis 1, is used to assist in the lifting and adjustment of the snow removal assembly; And a transmission component disposed between the two sets of push plates 202 for transmitting the push plates 202 when the two sets of push plates 202 push snow at different times; It should be noted that: through the cooperation of the tracked chassis 1, the snow removal component, and the lifting component, the surface of the floating photovoltaic panels along the travel path is pushed to remove snow, thus achieving the effect of snow removal. During the snow removal process, through the cooperation of the telescopic component, the sliding component, and the transmission component, when the snow removal is uneven, the length of the push plate 202 is reduced to decrease the snow removal length and snow removal resistance on that side. This allows the snow removal resistance on both sides of the push plate 202 to quickly become balanced, reducing the lateral overturning moment caused by the asymmetry of the resistance on both sides of the push plate 202. This prevents the snow removal robot from running off course, tilting, or getting stuck when performing snow removal operations on the floating photovoltaic platform, ensuring normal snow removal operations. In addition, it should be noted that in the initial state, the two sets of push plates 202 have the same length.

[0020] Preferably, the transmission assembly includes a connecting plate 401 disposed between the two sets of push plates 202, and the shape of the connecting plate 401 matches that of the push plate 202. It should be noted here that by keeping the shape of the connecting plate 401 consistent with that of the pusher plate 202, the connecting plate 401 and the two sets of pusher plates 202 can form a relatively integrated plate during the snow pushing process, thus ensuring the snow pushing effect. An installation assembly for auxiliary installation connection is provided between the connecting plate 401 and the two sets of first plates 2021. Two sets of mounting brackets 402 are symmetrically arranged between the two sets of push plates 202. The mounting brackets 402 are fixed on the connecting plate 401. A pull rope 403 is connected to the mounting bracket 402. One end of the pull rope 403 is located inside the slide groove 2022 and fixed to the second plate 2023. A support assembly for supporting the pull rope 403 is provided inside the slide groove 2022. It should be noted here that when the snow accumulation on the front side of the two sets of push plates 202 differs significantly, the torque deviation caused by the different snow accumulation on the push plates 202 will cause the push plate 202 with more snow accumulation to further retract towards the L-shaped frame 201. The movements of the two sets of push plates 202 are not synchronized. During the asynchronous movement of the two sets of push plates 202, the push plate 202 with a smaller retraction amplitude remains in contact with the connecting plate 401, while the push plate 202 with a larger retraction amplitude, due to its continued movement, will no longer attract and resist the iron block 502 and the magnetic block 503 on the push plate 202. At this time, the push plate 202 separates from the connecting plate 401. During the separation process, the second plate 2023 on the push plate 202 at this position is pulled by the pulling action of the pull rope 403 of the mounting frame 402 on the connecting plate 401.

[0021] Preferably, the mounting assembly includes a mounting plate 501 fixed to the front side of the connecting plate 401. On the side of the mounting plate 501 opposite to the first plate 2021, an iron block 502 and a magnetic block 503 for magnetic fixation are respectively fixed. A positioning assembly for positioning during the installation process is provided between the first plate 2021 and the mounting plate 501. It should be noted here that during the installation process, the mounting plate 501 is connected to the first plate 2021 by the magnetic force between the iron block 502 and the magnetic block 503. In addition, after the first plate 2021 and the mounting plate 501 are installed by magnetic force, they can be separated from each other during subsequent pulling due to the limited magnetic attraction force.

[0022] Preferably, the positioning component includes multiple sets of positioning holes 601 formed on the mounting plate 501, and multiple sets of positioning pins 602 are fixed on the first plate 2021, which are respectively inserted into and positioned in each set of positioning holes 601. It should be noted here that: the multiple sets of positioning holes 601 and positioning pins 602 facilitate the positioning of the mounting plate 501 during the installation process; In addition, the positioning pin 602 is located on the side of the first plate 2021 away from the L-shaped frame 201. The position setting facilitates the effective separation of the push plate 202, which undergoes further contraction during the force-induced contraction movement, from the mounting plate 501.

[0023] Preferably, the sliding assembly includes multiple sets of fixing blocks 701 fixed on the inner wall of the slide groove 2022. A T-shaped rod 702 is slidably connected to the fixing block 701. One end of the T-shaped rod 702 is fixed to the second plate 2023. A first spring 703 is sleeved on the outer side of the T-shaped rod 702. The two ends of the first spring 703 are respectively abutted against the second plate 2023 and the fixing block 701. It should be noted here that: the multiple sets of fixing blocks 701 and T-shaped rods 702 facilitate the sliding guidance of the second plate 2023 after being subjected to force. During the movement of the second plate 2023, the first spring 703 is deformed by force to generate elastic force. Through the elastic force of the first spring 703, the second plate 2023 is easily reset after movement.

[0024] Preferably, the telescopic assembly includes multiple sets of sleeves 301 fixed on the L-shaped frame 201, with a sliding rod 302 slidably connected on the sleeve 301. One end of the sliding rod 302 is fixed to the first plate 2021, and a second spring 303 is sleeved on the outside of the sleeve 301. The two ends of the second spring 303 are respectively abutted against the first plate 2021 and the L-shaped frame 201. It should be noted that the connection between the multiple sets of sleeves 301 and the slide rods 302 facilitates the synchronous movement of the push plate 202 while the L-shaped frame 201 is moving up and down. In addition, the sliding of the slide rods 302 on the sleeves 301 facilitates the telescopic connection between the push plate 202 and the L-shaped frame 201. During the telescopic movement, the second spring 303 will deform and generate elastic force. The elastic force of the second spring 303 facilitates the reset of the push plate 202 and the L-shaped frame 201 after the telescopic movement.

[0025] Preferably, the support assembly includes two sets of mounting shafts 801 rotatably connected inside the slide 2022, with support rollers 802 fixed on the mounting shafts 801, and a pull rope 403 passing through the two sets of support rollers 802 and abutting against each other; It should be noted here that the support roller 802 on the mounting shaft 801 supports the pull rope 403, making it easier for the pull rope 403 to be pulled more stably.

[0026] Preferably, the lifting assembly includes a U-shaped frame 901 fixed to the front side of the tracked chassis 1, a lifting plate 902 is provided on the U-shaped frame 901, a connecting frame 903 is fixed on the lifting plate 902, the connecting frame 903 and the L-shaped frame 201 are detached and installed by bolts, and a drive assembly for driving the lifting plate 902 is provided on the U-shaped frame 901; the drive assembly includes a threaded sleeve 1001 fixed on the lifting plate 902, a threaded rod 1002 rotatably connected to the U-shaped frame 901, the threaded sleeve 1001 and the threaded rod 1002 are meshed with each other, a drive motor 1003 for driving the threaded rod 1002 is installed on the U-shaped frame 901, and two sets of guide rods 1004 are slidably connected to the lifting plate 902, the two sets of guide rods 1004 are symmetrically arranged on both sides of the threaded sleeve 1001, and the guide rods 1004 are fixed to the U-shaped frame 901; It should be noted here that: when the drive motor 1003 is started, the threaded rod 1002 is driven to rotate by the drive motor 1003. During the rotation of the threaded rod 1002, the lifting plate 902 is subjected to force and moves through the mutual meshing transmission between the threaded rod 1002 and the threaded sleeve 1001. During the movement of the lifting plate 902, the sliding guidance of the lifting plate 902 after being subjected to force is achieved through the two sets of guide rods 1004, so that the lifting plate 902 after being subjected to force moves down on the U-shaped frame 901. During the descent, the L-shaped frame 201 is driven to descend synchronously through the connecting frame 903. During the movement of the L-shaped frame 201, the two sets of push plates 202 are driven to descend synchronously through the connection between the multiple sets of sleeves 301 and the slide rods 302. In addition, the working principle and control method of the drive motor 1003 are common drive components, and will not be described in detail here.

[0027] This solution describes a snow removal device for offshore photovoltaic panels, comprising the following steps: When using a snow removal robot to remove snow from offshore photovoltaic panels, the snow removal robot is placed on the surface of the offshore photovoltaic panels. After placement, the snow removal robot moves on the surface of the offshore photovoltaic panels through the driving action of the tracked chassis 1. During the snow removal robot's movement, the drive motor 1003 is started, driving the threaded rod 1002 to rotate. As the threaded rod 1002 rotates, the meshing transmission between it and the threaded sleeve 1001 causes the lifting plate 902 to move under force. During this movement, two sets of guide rods 1004 guide the sliding motion of the lifting plate 902, causing it to descend on the U-shaped frame 901. During this descent, the connecting frame 903 drives the L-shaped... The frame 201 descends synchronously. During the movement of the L-shaped frame 201, the connection between multiple sets of sleeves 301 and slide rods 302 drives the two sets of push plates 202 to descend synchronously. Through the descent of the push plates 202, the first plate 2021 comes into contact with the surface of the marine photovoltaic panel. Through this contact, the first plate 2021 and the second plate 2023 on the push plates 202 can push snow away from the surface of the marine photovoltaic panel along the travel path when the snow removal robot is moving. Finally, the snow accumulated on the front side of the push plates 202 falls from the side of the marine photovoltaic panel, achieving the effect of snow removal. When snow removal is performed by moving the two sets of pushers 202, snow will accumulate on the front side of the pushers 202 as the tracked chassis 1 moves (see...). Figure 7 and Figure 8As snow accumulates, it exerts a torque on the first plate 2021 and the second plate 2023 of the pusher plate 202. With the continued movement of the L-shaped frame 201, the pusher plate 202 contracts relative to the L-shaped frame 201 as snow accumulates in front of it. During this contraction, when the amount of snow accumulated in front of the two sets of pusher plates 202 is relatively equal (with a small deviation), the degree of relative contraction of the two sets of pusher plates 202 towards the L-shaped frame 201 is relatively consistent, and the movement of the two sets of pusher plates 202 remains synchronized (see...). Figure 7 At this time, the first plate 2021 and the second plate 2023 on the two sets of push plates 202 are in the same state. During the synchronous movement of the two sets of push plates 202, due to the magnetic attraction between the mounting plate 501 on the connecting plate 401 and the two sets of first plates 2021 respectively, the connecting plate 401 moves with the synchronous movement of the two sets of push plates 202. When the snow accumulation on the front side of the two sets of pushers 202 differs significantly, the difference in torque exerted on the pushers 202 by the different snow accumulation causes the pusher 202 with more snow accumulation to undergo further contraction towards the L-shaped frame 201 (see...). Figure 8 The two sets of push plates 202 do not move synchronously. During this asynchronous movement, the push plate 202 with a smaller contraction amplitude remains in contact with the connecting plate 401, while the push plate 202 with a larger contraction amplitude, due to its continued movement, causes the iron block 502 and the magnetic block 503 on the push plate 202 to no longer attract and resist each other. At this time, the push plate 202 separates from the connecting plate 401 (see...). Figure 9 During the separation process, the second plate 2023 on the push plate 202 at that position is pulled by the pulling action of the pull rope 403 on the mounting bracket 402 on the connecting plate 401. During the pulling process, the second plate 2023 under force is guided by the sliding block 701 and the T-shaped rod 702 on the sliding assembly, causing the second plate 2023 under force to retract towards the inside of the sliding groove 2022 of the first plate 2021, reducing the snow-pushing length of the push plate 202 at that position. Therefore, the accumulation on the front side of the push plate 202... When the snow accumulation differs significantly, the transmission system causes relative movement between the two sets of push plates 202, reducing the length of the push plate 202 with more snow accumulation on the front side. By reducing the length, the snow-pushing length and snow-pushing resistance on that side are reduced, allowing the snow-pushing resistance on both push plates 202 to quickly become more balanced (with a relatively low deviation). This reduces the lateral overturning moment caused by the asymmetrical resistance of the push plates 202 on both sides, preventing the snow removal robot from running off course, tilting, or getting stuck when performing snow removal operations on floating photovoltaic platforms at sea, thus ensuring normal snow removal operations.
