Description

Technical Field

[0001] This utility model relates to the field of water transportation technology, specifically to a water-based photovoltaic equipment transportation device. Background Technology

[0002] As an emerging form of clean energy utilization, floating photovoltaic power generation has significant advantages such as saving land resources, reducing water evaporation, and improving power generation efficiency. In recent years, it has been widely used in lakes, reservoirs and other water bodies.

[0003] During project construction, standardized transport vessels are typically used as the primary mode of transportation to move various equipment, such as photovoltaic brackets, battery modules, and inverters, from the shore to the floating installation platform. These transport vessels are mostly manufactured and sold by the same company, characterized by fixed specifications and batch supply.

[0004] However, due to the wide construction area, diverse equipment models, and significant size differences in various equipment types involved in floating photovoltaic projects, the existing transport vessels are limited in size and specifications, making it difficult to adapt to the transportation needs of equipment of different sizes. Construction units often need to purchase multiple vessels of different capacities to meet the diverse transportation tasks on site. This not only increases equipment procurement costs but also leads to low vessel utilization and complex on-site scheduling, thus restricting the overall economic benefits and construction efficiency of the project. Utility Model Content

[0005] This utility model provides a waterborne photovoltaic equipment transportation device to solve the problem of insufficient adaptability caused by the fixed specifications of traditional standardized vessels.

[0006] The floating photovoltaic equipment transport device provided by this utility model includes a frame structure, multiple buoyancy components, a cargo platform, and a power unit. The frame structure is assembled from multiple rods via detachable connectors; multiple buoyancy components are detachably installed on the frame structure to provide buoyancy; the cargo platform is positioned above the frame structure to support the floating photovoltaic equipment; the power unit is installed on the frame structure and provides power for movement in the water; wherein the number and / or installation position of the buoyancy components can be adjusted as needed to change the cargo capacity of the floating photovoltaic equipment transport device.

[0007] Beneficial effects: By assembling the frame structure with detachable connectors, the frame size can be flexibly expanded or reduced according to the size and weight requirements of the equipment to be transported. Furthermore, the number and installation position of buoyancy components can be adjusted as needed, achieving dynamic matching of cargo capacity by adding or removing buoyancy components. This adapts to the transportation needs of different specifications of equipment such as photovoltaic brackets and inverters, avoiding the inadequacy of traditional standardized vessels due to their fixed specifications. For example, when transporting large equipment, buoyancy components can be added or positioned further out to provide a larger and more stable load-bearing platform; when transporting small parts, buoyancy components can be reduced to decrease operating resistance and save energy.

[0008] In one alternative embodiment, the frame structure includes multiple steel pipes and connecting clips for connecting adjacent steel pipes.

[0009] Beneficial effects: By configuring the frame structure with multiple steel pipes and connecting clips, stable connections between the steel pipes can be achieved simply by locking the clips during installation, shortening the on-site deployment and retrieval time of the transport device. Simultaneously, it allows for lateral, longitudinal, and diagonal connections at any node, enabling on-demand expansion and installation to adapt to different loading requirements.

[0010] In one alternative embodiment, the buoyancy component is selected as a sealed oil drum.

[0011] Beneficial effects: By using sealed oil drums as buoyancy components, existing resources can be fully utilized and procurement costs reduced. Simultaneously, the cylindrical structure of the oil drums exhibits isotropic stress distribution characteristics, which can uniformly transfer dynamic loads to the frame structure when encountering water flow impacts, thereby improving the stability of the transport equipment.

[0012] In one alternative implementation, the loading platform includes wooden formwork laid on the frame structure.

[0013] Beneficial effects: By laying wooden formwork on top of the frame structure, the procurement cost is far lower than that of specially customized metal gratings or fiberglass platforms, due to the common availability and low price of wooden formwork. Furthermore, the lightweight nature of wooden formwork makes it easy to handle and cut. During on-site assembly, it can be quickly cut and spliced ​​using common tools (such as a handsaw) according to the specific dimensions and shape of the frame structure, perfectly covering frames of any size and shape. This allows for the continuous laying of the loading platform, ensuring that it can quickly adapt to different loading needs.

[0014] In one alternative embodiment, the surface of the wooden template is provided with anti-slip protrusions.

[0015] Beneficial effects: By providing anti-slip protrusions on the surface of the wooden template, the coefficient of friction between the template and the equipment can be increased, limiting the tendency of the equipment to slide horizontally above the loading platform and reducing the risk of equipment damage and falling into water.

[0016] In one optional embodiment, the power unit includes a steering input mechanism, a propulsion mechanism, a steering actuator, and a controller. The steering input mechanism is configured to receive steering commands from a user; the propulsion mechanism is rotatably mounted on a steering bracket, which is rotatably mounted about a vertically positioned steering axis, and includes a propeller that generates thrust and a power source that drives the propeller; the steering actuator includes a steering drive and a transmission assembly, the steering drive being fixed to the platform, and its output end being connected to the steering bracket via the transmission assembly; the controller is electrically connected to the steering input mechanism and the steering drive, and is configured to control the movement of the steering drive according to steering commands; wherein the steering drive is configured to drive the steering bracket to rotate about the axis of the steering axis via the transmission assembly, thereby changing the orientation of the propulsion mechanism as a whole to switch the thrust direction of the propeller.

[0017] Beneficial effects: By receiving commands through the steering input mechanism and executing them through the controller's electrically controlled steering drive, and by rotating the entire propulsion mechanism, including the propeller and power source, around the vertical axis, the thrust direction of the propeller can be changed, thereby changing the direction of movement of the device.

[0018] In one alternative embodiment, the transmission assembly includes a linkage structure, one end of which is hinged to the output end of the steering drive member, and the other end of which is hinged to a rocker arm fixed to the steering bracket.

[0019] Beneficial effects: By using a linkage structure with its two ends hinged to the output end of the steering drive and the rocker arm on the steering bracket, the linear or rotary motion output by the steering drive can be efficiently and accurately and reliably converted into the rotary motion required by the steering bracket, thereby driving the propulsion mechanism to change its orientation and switch the thrust direction of the propeller.

[0020] In one alternative implementation, the steering input mechanism includes a steering wheel and an encoder, the encoder being disposed on the steering wheel for detecting the rotation angle of the steering wheel and generating steering commands.

[0021] Beneficial effects: By using a steering wheel as an input device and installing an encoder on it, the physical quantity of the steering wheel's mechanical rotation angle is converted into steering commands (i.e., digital or analog electrical signals representing steering intentions) in real time and with precision. This provides the controller with a standard, quantifiable input signal for receiving and processing steering commands. Simultaneously, it enables continuous, smooth, and precise control of the transport device's heading.

[0022] In one alternative embodiment, the floating photovoltaic equipment transport device further includes a protective fence surrounding the cargo platform.

[0023] Beneficial effects: By installing protective railings on the loading platform, a physical barrier is formed to prevent personnel and equipment on the platform from falling into the water during swaying, thus improving the safety performance of the device. At the same time, the railings themselves can also be used as handrails, making it easier for personnel to maintain their balance in bumpy environments, thereby indirectly improving the stability and efficiency of the operation.

[0024] In one alternative implementation, the protective fence is constructed from multiple steel pipes.

[0025] Beneficial effects: The use of steel pipes allows for flexible adjustments based on actual needs. For example, when transporting oversized equipment, sections of the fence can be temporarily raised; when loading and unloading openings are required, certain sections can be quickly removed. Furthermore, the excellent mechanical strength of steel pipes ensures that the protective fence not only effectively prevents equipment and personnel from falling, but also serves as a robust rigid structure. When firmly connected to the main frame, it further enhances the overall rigidity and stability of the entire transport device, better resisting the impact of wind and waves.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0031] According to an embodiment of this utility model, a waterborne photovoltaic equipment transportation device is provided, such as... Figure 1 As shown, it includes a frame structure 1, multiple buoyancy components 2, a cargo platform 3, and a power unit 4.

[0032] The frame structure 1 is assembled from multiple rods via detachable connectors; multiple buoyancy components 2 are detachably installed on the frame structure 1 to provide buoyancy; a cargo platform 3 is positioned above the frame structure 1 to support the floating photovoltaic equipment; a power unit 4 is installed on the frame structure 1 and provides power for movement in the water; the number and / or installation position of the buoyancy components 2 can be adjusted as needed to change the cargo capacity of the floating photovoltaic equipment transport device, thereby adapting to the transportation needs of floating photovoltaic equipment of different sizes and weights.

[0033] This configuration, by assembling frame structure 1 with detachable connectors, allows for flexible expansion or reduction of the frame size according to the size and weight requirements of the equipment to be transported.

[0034] Furthermore, the quantity and installation position of the buoyancy components 2 can be adjusted as needed. By increasing or decreasing the buoyancy components 2, the cargo capacity can be dynamically matched, thereby adapting to the transportation needs of different specifications of equipment such as photovoltaic brackets and inverters, and avoiding the phenomenon of insufficient adaptability caused by the fixed specifications of traditional standardized ships.

[0035] For example, when transporting large equipment, the number of buoyancy components 2 can be increased and / or they can be placed in a more outer position to provide a larger and more stable bearing platform; when transporting small parts, the number of buoyancy components 2 can be reduced and / or they can be placed in a more inner position to reduce running resistance and save energy.

[0036] It can be noted that the frame structure 1 includes multiple steel pipes 11.

[0037] Furthermore, the frame structure 1 also includes a connecting buckle 12, which is used to connect adjacent steel pipes 11 at any connection node.

[0038] This configuration, by setting the frame structure 1 to be connected by multiple steel pipes 11 and connecting buckles 12, allows for a stable connection between the steel pipes 11 during installation simply by locking the buckles, thus shortening the on-site deployment and recovery time of the transportation device.

[0039] At the same time, it allows for horizontal, vertical, and diagonal connections at any node, enabling on-demand expansion and installation to adapt to different loading requirements.

[0040] It should be noted that the connecting buckle 12 is selected as follows: Figure 3 The standard scaffolding fixing cross buckle shown is not described in detail here.

[0041] It can be noted that the buoyancy component 2 is a sealed oil drum.

[0042] This setup, by using a sealed oil drum as the buoyancy component 2, can make full use of existing resources and reduce procurement costs.

[0043] Meanwhile, the cylindrical structure of the oil drum has isotropic stress distribution characteristics, which can uniformly transfer dynamic loads to the frame structure 1 when it encounters water flow impact, thereby improving the stability of the transportation equipment.

[0044] It can be noted that the loading platform 3 includes wooden formwork laid on the frame structure 1.

[0045] With this setup, wooden formwork is laid on top of frame structure 1. Since wooden formwork is common and inexpensive, its procurement cost is much lower than that of customized metal grilles or fiberglass platforms.

[0046] Meanwhile, the wooden template is lightweight and easy to handle and cut. During on-site assembly, it can be quickly cut and spliced ​​using ordinary tools (such as a hand saw) according to the specific size and shape of the frame structure 1, so as to perfectly cover any size and shape of the frame, realize the continuous laying of the loading platform 3, and ensure that the loading platform 3 can quickly adapt to different loading needs.

[0047] Furthermore, such as Figure 3 As shown, the surface of the wooden template is provided with anti-slip protrusions 311.

[0048] This design, with anti-slip protrusions 311 on the surface of the wooden template, increases the coefficient of friction between the template and the equipment, limiting the tendency of the equipment to slide horizontally above the loading platform 3, and reducing the risk of equipment damage and falling into water.

[0049] This can be achieved by purchasing building templates with embossed or textured surfaces, or by on-site mechanical processing (such as grooving or nailing anti-slip wooden strips).

[0050] In one embodiment, such as Figure 4 As shown, the power unit 4 includes a steering input mechanism, a propulsion mechanism, a steering actuator, and a controller 48.

[0051] The steering input mechanism is configured to receive steering commands from the user; the propulsion mechanism is rotatably mounted on a steering bracket 42, which is rotatably mounted around a vertically mounted steering shaft 43. The propulsion mechanism includes a propeller 44 that generates thrust and a power source 45 that drives the propeller 44; the steering actuator includes a steering drive 46 and a transmission assembly 47. The steering drive 46 is fixed to the loading platform 3, and its output end is connected to the steering bracket 42 via the transmission assembly 47; the controller 48 is electrically connected to the steering input mechanism and the steering drive 46 and is configured to control the movement of the steering drive 46 according to the steering command; wherein the steering drive 46 is configured to drive the steering bracket 42 to rotate around the axis of the steering shaft 43 via the transmission assembly 47, thereby changing the orientation of the propulsion mechanism as a whole to switch the thrust direction of the propeller 44.

[0052] With this configuration, commands are received through the steering input mechanism and executed by the controller 48 via the electrically controlled steering drive 46. By rotating the entire propulsion mechanism, including the propeller 44 and the power source 45, around the vertical axis, the thrust direction of the propeller 44 can be changed, thereby changing the direction of movement of the device.

[0053] It can be noted that in the above embodiment, the steering shaft 43 is the core component that bears and rotates.

[0054] It can be noted that in the above embodiment, the steering drive component 46 is selected as a servo motor. The servo motor is connected to the steering linkage via a push-pull rod and a ball joint drive. The steering linkage is connected to the steering bracket 42 via a push-pull rod and a ball joint drive. The steering bracket 42 rotates around the steering shaft 43 via a bearing.

[0055] Furthermore, the transmission assembly 47 includes a linkage structure, one end of which is hinged to the output end of the steering drive 46, and the other end is hinged to a rocker arm fixed to the steering bracket 42.

[0056] With this configuration, by using a linkage structure, and with its two ends respectively hinged to the output end of the steering drive 46 and the rocker arm on the steering bracket 42, the linear or rotary motion output by the steering drive 46 can be efficiently and accurately and reliably converted into the rotary motion required by the steering bracket 42, thereby driving the propulsion mechanism as a whole to change its orientation, so as to switch the thrust direction of the propeller 44.

[0057] It can be explained that the steering input mechanism includes a steering wheel 41 and an encoder. The encoder is mounted on the steering wheel 41 and is used to detect the rotation angle of the steering wheel 41 and generate steering commands.

[0058] With this configuration, by using the steering wheel 41 as an input device and setting an encoder on the steering wheel 41, the physical quantity of the mechanical rotation angle of the steering wheel 41 is converted into steering commands (i.e., digital or analog electrical signals representing steering intentions) in real time and accurately, providing a standard and quantifiable input signal for the controller 48 to receive and process steering commands.

[0059] At the same time, it can achieve continuous, smooth and precise control over the course of the transport device.

[0060] The encoder is electrically connected to the controller 48, and the steering wheel 41 is mounted on the frame structure 1 via a support rod (such as a steel pipe 11).

[0061] Similarly, the power source 45 is selected as an electric motor, and the output end of the motor is connected to the transmission shaft through a coupling. The transmission shaft is fixedly installed at the rotation center of the propeller 44 by a key and a nut.

[0062] In this way, the power of the motor can be transmitted to the propeller 44, so that the propeller 44 can generate thrust after rotating in the water.

[0063] It should be noted that, as Figure 4 As shown, the power source 45, drive shaft, and propeller 44 are all mounted on the frame structure 1.

[0064] like Figure 1 As shown, the waterborne photovoltaic equipment transport device also includes a protective fence 5 set up around the cargo platform 3.

[0065] This setup, by providing a protective fence 5 on the cargo platform 3, forms a physical barrier to prevent personnel and equipment on the cargo platform 3 from falling into the water during swaying, thus improving the safety performance of the device.

[0066] At the same time, the fence itself can also be used as a handrail, making it easier for people to maintain their balance in bumpy environments, thereby indirectly improving the stability and efficiency of the operation.

[0067] It can be noted that the protective fence 5 is also constructed from multiple steel pipes 11.

[0068] This setup, constructed using steel pipes (11), allows for flexible adjustments based on actual needs. For example, when transporting oversized equipment, sections of the fence can be temporarily raised; and when loading and unloading openings are required, certain sections can be quickly removed.

[0069] Meanwhile, the steel pipe 11 itself has excellent mechanical strength. The protective fence 5 constructed from it can not only effectively prevent equipment and personnel from falling, but also, as a sturdy rigid structure, after being firmly connected with the main frame, further enhance the overall rigidity and stability of the entire transportation device, and can better resist the impact of wind and waves.

[0070] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
