Description

Technical Field

[0001] This utility model relates to the field of waterborne photovoltaic operation platforms, specifically to a detachable waterborne photovoltaic operation platform. Background Technology

[0002] With the rapid development of my country's photovoltaic industry, in order to save land resources, photovoltaic power stations are gradually expanding into water areas, with many projects located in fishponds, lakes, reservoirs, and other water bodies. However, the operation and maintenance of these floating photovoltaic power stations face multiple challenges:

[0003] 1. Low efficiency in cross-area access: Solar panels in power plants are often distributed across hundreds of isolated water units, such as separated fishponds, requiring frequent cross-area operations for maintenance. Traditional transport vehicles such as rubber boats are bulky and cannot be directly transported by power plant maintenance vehicles. Each use requires a cumbersome process of inflation, deflation, and dredging, taking several hours and severely restricting maintenance efficiency. If a separate boat is deployed for each water area, maintenance costs will skyrocket, and there is also a risk of equipment theft.

[0004] 2. Insufficient working height and safety: The photovoltaic panel installation base is usually 2-3 meters above the water surface. Traditional vessels lack stable lifting and lowering equipment, making it difficult for maintenance personnel to safely reach the work area. Especially in windy and wavy environments, the vessel is easily affected by water currents and pitches, further increasing the risks of working at height.

[0005] 3. The equipment compatibility contradiction is prominent, and existing transportation tools are difficult to balance portability and functionality: small portable boats have limited carrying capacity and cannot carry large maintenance equipment; while engineering vessels with working platforms are limited by size and are difficult to be flexibly dispatched in dispersed waters.

[0006] In existing technologies, such as Chinese utility model patent CN220701325U, a foam board type floating photovoltaic operation platform is disclosed, including a bottom frame and several foam boards. The bottom frame includes a receiving space for fixing the foam boards, and the foam boards are fixed in the receiving space. A footboard is fixedly laid on the bottom frame, and a fence is provided along the edge of the bottom frame. A drive paddle is provided at one end of the bottom frame. The drive paddle propels the operation platform to move in the water. However, in practical applications, this method is difficult to use across ponds / water areas. A separate operation platform is required for each separated body of water, and the utilization efficiency is low, resulting in waste. Furthermore, the foam boards are easily damaged during operation and maintenance, affecting their service life. Utility Model Content

[0007] In order to overcome the technical defects of the above-mentioned floating photovoltaic power station in daily operation and maintenance, such as the inconvenience of building and transporting the floating operation platform, which makes it impossible to use it in multiple water areas and multiple ponds, this utility model provides a detachable floating photovoltaic operation platform.

[0008] To solve the above problems, this utility model is implemented according to the following technical solution:

[0009] A detachable floating photovoltaic operation platform is used for the operation and maintenance of photovoltaic modules on water. The photovoltaic operation platform includes a base and a main body of the operation platform built on the base. The base includes several pontoons and several fasteners. The pontoons have a cubic structure. Each vertical edge of the four outer sides of the pontoons is equipped with a buckle. The vertical distance between the buckle on each vertical edge and the bottom surface of the pontoon on the same side decreases or increases sequentially. After the buckles between adjacent pontoons overlap, the fasteners pass through the overlapping position of the buckles to splice the adjacent pontoons together to form the base.

[0010] Preferably, the main body of the work platform is built on the base, and a number of ladders and support columns are provided at the edge of the lower surface of the main body of the work platform. The ladders and support columns are hinged to the main body of the work platform. A fence is provided at the upper edge of the main body of the work platform. The main body of the work platform is provided with a number of through holes for fixing the main body of the work platform to the base. The through holes are used to fix the main body of the work platform to the base through cables.

[0011] Preferably, a drive device is connected to one side of the base, and the drive device is used to control the movement of the base.

[0012] Preferably, the four sides of the cube structure in the float are provided with concave and convex structures, and the concave and convex structures of each adjacent float can be adapted to each other.

[0013] Preferably, the pontoon and the fastener are integrally formed from polyethylene material by blow molding.

[0014] Preferably, the float is provided with a water inlet on its side, which is used to adjust the buoyancy of the float.

[0015] Preferably, the vertical ridge is provided with a connecting groove, a notch and a retaining ring from top to bottom; the fastener is adapted to each of the connecting groove, the notch and the retaining ring on the vertical ridge by insertion.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model discloses a detachable floating photovoltaic operation platform, applied to the operation and maintenance of photovoltaic modules on water. The base size can be adjusted according to actual operating conditions, providing an adjustable platform for floating photovoltaic operations. The floats are designed as cubic structures, and a suitable number of floats are assembled to form the base. The floats can be disassembled for transport, improving transportation convenience. Each of the four vertical edges on the four sides of the cubic structure is equipped with a buckle. The height of the buckles on the vertical edges decreases sequentially in a clockwise direction, and the spacing of the buckles during actual installation is appropriate, allowing different floats to be connected. The buckles on adjacent floats overlap; fasteners are inserted into the buckles on adjacent floats to fix the floats in place. This makes the base of the photovoltaic operation platform easy to assemble and more stable. It is easy to assemble and disassemble, facilitating transportation.

[0018] Therefore, this application ensures the ease of assembly and disassembly, stability and portability of the operating platform, effectively solving the problem that the floating photovoltaic operating platform can only be used in one body of water and cannot be used across water bodies and fishponds. This results in a photovoltaic power station being built in many bodies of water, requiring the construction of multiple operating platforms, which leads to low utilization efficiency, waste and high costs. This application saves a lot of costs in building floating photovoltaic operating platforms. Attached Figure Description

[0029] like Figures 1-4 As shown, the present invention discloses a detachable waterborne photovoltaic operation platform, which is used for the operation and maintenance of photovoltaic modules on water. The photovoltaic operation platform includes a base 1 and an operation platform body 2 built on the base 1. The base 1 includes several floats 11 and several fasteners 12. The floats 11 are cubic structures. Each vertical edge 13 on the four outer sides of the floats 11 is equipped with a buckle 14. The vertical distance between the buckle 14 on each vertical edge 13 and the bottom surface of the float 11 on the same side decreases or increases sequentially. After the buckles 14 between adjacent floats 11 overlap, the fasteners 12 pass through the overlapping position of the buckles 14 to splice the adjacent floats 11 together to form the base 1.

[0030] Understandably, such as Figure 2As shown, the float 11 has a cubic structure, and each of the four vertical edges 13 on the four sides of the cubic structure is provided with a buckle 14 of different height. In one embodiment, the height of the buckle 14 on the vertical edge 13 decreases sequentially in a clockwise direction, and the spacing of the buckle 14 during actual installation is appropriate; the connecting buckles 14 are of the same size, but the heights of each connecting buckle 14 are different, and the buckles 14 can be staggered when the floats 11 are arranged and connected. This allows every four floats 11 to be spliced ​​together, and four cubic floats 11 can also be spliced ​​together to form a cubic base 1. According to the actual operation of the floating photovoltaic power station, multiple cubic floats 11 can be arranged and spliced ​​in an orderly manner, with the buckles 14 overlapping and staggered, and fasteners 12 are inserted into the spliced ​​buckles 14 to fix them and form a floating base 1.

[0031] Furthermore, the main body 2 of the work platform is built on the base 1. Several ladders 21 and several support columns 22 are provided at the edge of the lower surface of the main body 2 of the work platform. The ladders 21 and the support columns 22 are hinged to the main body 2 of the work platform. A fence 23 is provided at the upper edge of the main body 2 of the work platform. Several through holes 24 are provided on the main body 2 of the work platform. The through holes 24 are used to fix the main body 2 of the work platform to the base 1. The through holes 24 are used to fix the main body 2 of the work platform to the base 1 through cables 25.

[0032] Understandably, such as Figure 1 As shown, the main body 2 of the work platform is built on the base 1. Several ladders 21 and several support columns 22 are provided along the edge of the lower surface of the main body 2. The main body 2 is hinged to the ladders 21 and support columns 22 to form a foldable work platform. The lower ends of the support columns 22 are equipped with silicone anti-slip pads to increase stability. The support columns 22 and ladders 21 support the main body 2, making it easy for maintenance personnel to climb to the top. Through holes 24 are welded to the four corners of the foldable work platform 2. Cables 25 secure the main body 2 to the base 1 through these through holes 24. In one embodiment, the cable 25 is a windproof pull rope. Tightening the cable 25 to the through holes 24 and the four corner buckles 14 of the base 1 stably fixes the main body 2 to the base 1. The top surface of the foldable work platform 2 has an anti-slip pattern for maintenance personnel to walk and work on. A railing 23 is provided along the upper edge of the main body 2 to ensure the safety of maintenance personnel.

[0033] Furthermore, a drive device 15 is connected to one side of the base 1, and the drive device 15 is used to control the movement of the base 1.

[0034] A drive unit 15 is provided on one side of the base 1. The drive unit 15 includes a drive motor 151, a blade 152, and a control lever 154. Specifically, the drive unit 15 has a control module inside. The drive motor 151 and the blade 152 are fixed on a rotatable bracket 153. The control module is activated by the control lever 154 to control the deflection of the bracket 153, thereby controlling the movement direction of the base 1. In one embodiment, the operator can activate the control module through the control lever 154 of the drive unit 15 to control the running speed of the drive motor 151, thereby controlling the movement speed of the base 1.

[0035] Furthermore, the four sides of the cube structure in the float 11 are provided with concave and convex structures 16, and the concave and convex structures 16 of each adjacent float 11 can be adapted to each other.

[0036] Understandably, the four sides of the cube structure of the float 11 are provided with concave and convex structures 16, and the concave and convex structures 16 of every two floats 11 can be adapted to each other. In one embodiment, the concave and convex structures 16 on the sides of the cube structure float 11 are set as mutually adaptable arcs. The two floats 11 are arranged to form an arc shape to adapt to each other and match the shape, making the connection of the floats 11 more stable. This adaptable arc shape stability can also be achieved in a variety of ways, such as gear-type fitting, puzzle-type fitting, etc.

[0037] Furthermore, the pontoon 11 and the fastener 12 are integrally formed from polyethylene material by blow molding.

[0038] Blow molding is a rapid molding process that can process polyethylene material into the required shape and size in a short time, resulting in high production efficiency and suitability for large-scale production. This process can adapt to molds of different shapes and sizes, thus producing products with various complex shapes. Polyethylene material has good thermoplasticity and flowability, making it well-suited for blow molding and less prone to decomposition or discoloration during the molding process. Blow molding allows the polyethylene material to fit tightly into the mold, forming an integral structure with high structural strength and good sealing performance. It effectively makes the base suitable for water use, as it is not easily corroded. Polyethylene material itself has excellent chemical corrosion resistance and environmental stress cracking resistance; products made through blow molding can better utilize these properties, maintaining good performance under harsh environmental conditions and extending service life. Regarding cost and efficiency...

[0039] In one embodiment, the floats 11 and fasteners 12 are made primarily of high-molecular-weight polyethylene and are integrally formed by blow molding, resulting in strong buoyancy. Multiple floats 11 are arranged in an orderly manner and spliced ​​together with fasteners 12 to fix the floats 11 into a floating base 1. During the integral blow molding process, material utilization is high, waste is minimal, and production costs are effectively reduced. Compared with traditional injection molding and extrusion molding processes, integral blow molding has a shorter production cycle, enabling rapid response to market demands and improving production efficiency. Polyethylene is a recyclable plastic, and integrally blow-molded products can be recycled and reused after use, meeting the requirements of environmental protection and sustainable development.

[0040] Furthermore, a water inlet 17 is provided on the side of the float 11, which is used to adjust the buoyancy of the float 11.

[0041] Understandably, such as Figure 3 As shown, the water inlet 17 is used to adjust the operating range and buoyancy of the float 11.

[0042] The principle of adjusting buoyancy by filling the float 11 with water is mainly based on Archimedes' principle and the conditions for floating and sinking of objects. Archimedes' principle states that an object immersed in a liquid experiences an upward buoyant force, the magnitude of which is equal to the weight of the liquid displaced by the object. When water is filled into the float 11, the overall weight of the float 11 increases, and its displaced volume also changes, thus affecting the magnitude of the buoyancy.

[0043] When water is added to the float 11, the overall weight of the float 11 increases. If the float 11 remains afloat, according to the conditions for floating and sinking, the buoyant force on the float 11 must be equal to its increased weight, thus the buoyant force will also increase accordingly. After being filled with water, the increased weight of the float 11 causes it to sink deeper in the water, thereby displacing more water. According to Archimedes' principle, the more water displaced, the greater the buoyant force. Filling with water can also change the position of the center of gravity of the float 11. If the center of gravity of the float 11 is lower, its stability in the water will be better, which helps to maintain the balance of buoyancy and makes the float 11 float more stably on the water surface.

[0044] Furthermore, the vertical ridge 13 is provided with a connecting groove 18, a notch 19 and a buckle 14 from top to bottom; the fastener 12 is adapted to each of the connecting groove, the notch 19 and the buckle 14 on the vertical ridge 13 by insertion.

[0045] Understandably, such as Figure 4As shown, the fastener 12 has a column head 121 at its upper end, which is adapted to the connecting groove 18 on the vertical edge 13. This is used to connect the joints of the various floats 11 on the base 1 when the floats 11 are assembled into the base 1. A buckle 122 is provided below the column head 121, which is adapted to the recess 19. A hook 123 is provided at the lower end of the fastener 12, which passes through the retaining ring 14. The buckle 122 and the hook 123 fix the various floats 11, making the assembly of the base 1 convenient and ensuring the stability of the base 1. In one embodiment, when the floats 11 are assembled into the base 1, there are retaining rings 14 on the four vertical edges 13 of the floats 11 for connecting the retaining rings on the four floats 11. The four floats 14 overlap and align the buckles 14. There are connecting grooves 18 at the four corners of the upper part of the floats 11, and notches 19 below the connecting grooves 18. Fasteners 12 are inserted into the gaps at the connection points of the four floats 11. The post head 121 on the fastener 12 matches the shape and curvature of the connecting groove 18, filling the gaps. The buckles 122 on the fastener 12 and the hooks 123 at the lower end of the fastener 12 secure the four floats 11, ensuring the stability of the floats 11 when assembled into the base 1. The upper surface of the floats 11 has anti-slip patterns to increase surface friction and prevent people from slipping and falling into the water. The lower part of the floats 11 is placed in the water.

[0046] The working principle of the detachable waterborne photovoltaic operation platform described in this utility model is as follows:

[0047] Based on the actual operating environment of the floating photovoltaic power station, several pontoons 11 are spliced ​​together to form a base 1. The quickly assembled base 1 facilitates operation and maintenance. A fastener 12 can be inserted into every four pontoons 11. After the base 1 is assembled, the foldable work platform body 2 is unfolded. The work platform body 2 is supported and erected on the base 1 using ladders 21 and support columns 22. After fixing the position, the through holes 24 are tightened and bound to the buckles 14 on the base using cables 25 to ensure the stability of the structure. The drive device 15 is fixed in the middle of one side of the base 1 to control the movement of the work platform, improving the efficiency of operation and maintenance of the floating photovoltaic power station.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
