Description

Technical Field

[0001] This invention belongs to the field of water surface photovoltaic installation technology, and more specifically, relates to an auxiliary device and its usage method suitable for the batch installation of water surface photovoltaic brackets. Background Technology

[0002] In recent years, floating photovoltaic (PV) systems have developed rapidly as a form of renewable energy utilization that combines land conservation and ecological benefits. Project sites have gradually expanded from early fishponds to natural or artificial water bodies with more complex hydrological conditions, and installed capacity has also shown a trend of large-scale growth. Against this backdrop, the floating PV support system, as a key infrastructure supporting PV modules and ensuring structural stability, directly affects the overall project's construction cycle and economic efficiency through its installation efficiency and construction safety.

[0003] Currently, the installation of photovoltaic (PV) brackets mainly relies on land-based construction equipment and manual labor. Existing PV bracket installation tools, transport equipment, and positioning fixtures are designed for flat, dry, and solid land surfaces with open working areas. Land-based bracket assembly, hoisting, and fixing equipment, for example, are based on land-based construction conditions in their structure, power configuration, and operation. They have high requirements for site flatness, foundation bearing capacity, and operating space, making them difficult to adapt directly to aquatic construction scenarios. In actual waterborne bracket installation, factors such as the small working area of ​​the floating platform, slippery platforms, dynamic changes in water depth, wind and wave disturbances, and high requirements for underwater foundation positioning accuracy limit the stable deployment and efficient operation of conventional land-based installation equipment. On-site construction can only be carried out primarily by manual labor, supplemented by simple tools. During construction, workers need to transport the support columns, beams, diagonal braces, connectors and other components to the work site one by one. Then, the assembly is completed by manual positioning, manual calibration and point-by-point tightening. The installation of a single support usually requires 4 to 5 workers to work together and make repeated adjustments in the same narrow work area. The process is complicated and the overall operation is highly dependent on manual operation and experience judgment.

[0004] The aforementioned existing technologies have inherent drawbacks in aquatic environments, such as high manpower input, high labor intensity, and low levels of mechanization and standardization. They are difficult to meet the engineering requirements of large-scale and complex floating photovoltaic power stations, directly resulting in low installation efficiency of floating photovoltaic supports, extended construction periods, and high engineering costs. This restricts the upgrading of construction technology and large-scale promotion in the floating photovoltaic industry. Therefore, developing an auxiliary device for the installation of floating photovoltaic supports that is adaptable to aquatic conditions, easy to operate, safe, and efficient has become an urgent technical problem to be solved in this field.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1 Please refer to Figures 1 to 7 This invention provides an auxiliary device suitable for the batch installation of photovoltaic brackets on water surfaces, comprising: Two floating bodies 1, each of which is composed of several detachable pontoons 101, are used to provide a platform for water operations and buoyancy support; Two drive components 2, each of which is located at the bottom of the corresponding float 1, are used to realize the movement, turning and parking of the corresponding float 1 on the water surface; Two vertical telescopic support components 3 are provided, each of which is located at the middle of the upper end of the corresponding float 1, for adjusting the overall height of the hoisting assembly 4; The hoisting assembly 4 has its two ends connected to the movable ends of the two vertical telescopic support assemblies 3, respectively, for hoisting the photovoltaic bracket 5.

[0026] Understandably, during use, the float 1 is composed of several detachable pontoons 101, which not only facilitates transportation and rapid on-site assembly, but also allows for flexible adjustment of platform size and load-bearing capacity according to the conditions of the working water area, providing a stable and reliable foundation for construction personnel and equipment to operate on water. The drive component 2 is located at the bottom of the float 1, giving the whole machine the ability to move autonomously, turn precisely, and stop reliably, effectively overcoming the problems of inaccurate positioning and low efficiency caused by relying on manual rowing or external towing in the past. The vertical telescopic support component 3 is located at the middle of the upper end of the float 1, and can adjust the working height of the hoisting component 4 in real time according to changes in water depth or the required height of the bracket installation, ensuring the vertical accuracy and operational adaptability of the installation process. The two ends of the hoisting component 4 are respectively connected to the movable ends of the two sets of vertical telescopic support components 3 to form a stable bridging structure, which can efficiently and smoothly hoist the entire photovoltaic bracket 5, avoiding component collisions, falling into the water, or assembly errors caused by manual handling.

[0027] In an optional embodiment, the float 101 further includes: a side nut 101a and a side bolt 101b adapted to the side nut 101a; The float 101 has an internal cavity, and its four vertical corners are recessed inward to form vertical arc-shaped grooves. Each arc-shaped groove is provided with a horizontally arranged side nut 101a. The four side nuts 101a of each float 101 are staggered at different heights in the vertical direction. One of the side bolts 101b is threadedly connected to at least two side nuts 101a at adjacent corners of two adjacent floats 101, thereby achieving an efficient, stable and detachable connection between adjacent floats 101.

[0028] Understandably, during use, the pontoon 101 has an internal cavity to provide buoyancy, and its four vertical corners are recessed inward to form vertical arc-shaped grooves. Each groove is provided with horizontally arranged side nuts 101a. Among them, the side nuts 101a of two opposite corners are located on the same horizontal plane, while the side nuts 101a of two adjacent corners are not on the same horizontal plane. Thus, a side bolt 101b is simultaneously threaded to the non-coplanar side nuts 101a on two adjacent pontoons 101. This not only enhances the torsional and shear resistance of the overall structure, but also effectively avoids loosening or misalignment of the connection, significantly improving the stability and assembly accuracy of the float 1 in complex waters, and facilitating rapid on-site assembly and subsequent maintenance and disassembly.

[0029] In an optional embodiment, the upper surface of the float box 101 is uniformly provided with anti-slip textures to increase the friction coefficient of the contact surface, significantly enhance the adhesion between the shoe sole and the upper surface of the float box 101, and reduce the risk of slippage.

[0030] Furthermore, the drive assembly 2 includes: a propeller 201, a waterproof motor 202, a connecting column 203, and a drive connector 204; The drive connector 204 is fixedly disposed at the bottom end of the float 1; The connecting column 203 is fixedly disposed at the middle of the bottom end of the driving connector 204; The output shaft of the waterproof motor 202 is connected to the propeller 201, and the upper end of the waterproof motor 202 is fixedly connected to the bottom end of the connecting column 203. The thrust axis of the propeller 201 is parallel to the axis of the float 1, so that the overall steering, movement or precise parking of the auxiliary equipment can be completed by controlling the rotation direction and rotation speed of the two propellers 201 respectively.

[0031] Understandably, during use, the drive connector 204 is fixed to the bottom of the float 1, and the connecting column 203 is located in the middle of its bottom, providing stable support for the waterproof motor 202; the output shaft of the waterproof motor 202 drives the propeller 201, and its thrust axis is parallel to the axis of the float 1, so that when the equipment is equipped with two symmetrically arranged drive components 2, differential thrust can be generated by adjusting the rotation direction and speed of the two sets of propellers 201 respectively, thereby efficiently completing forward, backward, turning in place and precise parking actions.

[0032] It should be noted that in this embodiment, the waterproof motor 202 is a common waterproof motor in the prior art, such as D70L165. In other embodiments, other types of waterproof motors and rotating connection structures may also be used, which are not specifically limited here.

[0033] Furthermore, the vertical telescopic support assembly 3 includes: a lower support base 301, a vertical telescopic member 302, a diagonal brace 303, and an upper connecting base 304; The lower support 301 is cross-shaped and is detachably located at the middle of the upper end of the float 1. The vertical telescopic component 302 includes a fixed column 302a and a movable column 302b. The fixed column 302a is a hollow column, which is fixedly installed at the middle of the upper end of the lower support 301. One end of the movable column 302b passes through the fixed column 302a and is axially slidably connected to the fixed column 302a. The upper connecting seat 304 is a hollow columnar structure, which is movably sleeved on the outside of the movable column 302b and slides in cooperation with the movable column 302b. There are four diagonal braces 303, and one end of each diagonal brace 303 is fixedly connected to one end of the lower support 301, and the other end is fixedly connected to the corresponding side of the upper connecting seat 304.

[0034] Understandably, during use, the lower support 301 is cross-shaped and detachably installed at the upper middle part of the float 1, which facilitates transportation and on-site assembly; the fixed column 302a serves as the fixing part of the vertical telescopic component 302 and is vertically set at the center of the lower support 301, providing a basis for height adjustment; the four diagonal braces 303 respectively connect the corresponding parts of each end of the lower support 301 and the upper connecting seat 304, forming a spatial truss-type reinforced structure, which significantly improves the overall resistance to lateral forces and overturning.

[0035] In an optional embodiment, the vertical telescopic member 302 further includes: a hydraulic cylinder piston rod 302c, a hydraulic cylinder piston 302d, a hydraulic pump 302e, and a control motor 302f; The piston rod 302c of the hydraulic cylinder is located inside the fixed column 302a, and its upper end is connected to the bottom end of the movable column 302b. The cylinder piston 302d is slidably and sealed inside the fixed column 302a, and is coaxially and fixedly sleeved on the bottom end of the cylinder piston rod 302c; The hydraulic pump 302e is connected to the sealed chamber located below the piston 302d of the cylinder in the fixed column 302a via a hydraulic pipeline. The output shaft of the control motor 302f is connected to the hydraulic pump 302e via a transmission connection.

[0036] Understandably, during use, the upper end of the cylinder piston rod 302c is connected to the bottom end of the movable column 302b, and the lower end is coaxially fixedly fitted with the cylinder piston 302d, which is sealed and slidably located in the inner cavity of the fixed column 302a; the hydraulic pump 302e connects the sealed chamber between the fixed column 302a and the cylinder piston 302d through hydraulic pipelines, and is driven by the control motor 302f to supply pressure, thereby pushing the cylinder piston 302d and the cylinder piston rod 302c to move axially, driving the movable column 302b to extend and retract precisely.

[0037] Furthermore, the hoisting assembly 4 also includes: a hoisting beam 401, a guide rail 402, a slider 403, a crossbeam 404, and a photovoltaic bracket connector 405; The two ends of the lifting beam 401 are detachably connected to the upper ends of the two movable columns 302b by bolts. The guide rail 402 is fixedly disposed at the middle of the bottom end of the lifting beam 401 along the length direction of the lifting beam 401; The slider 403 is slidably disposed on the guide rail 402, and there are two of them; There are two crossbeams 404, and they correspond one-to-one with the sliders 403; the middle of the upper end of the crossbeam 404 is fixedly connected to the bottom end of the slider 403, and the horizontal projection of the crossbeam 404 is perpendicular to the horizontal projection of the suspension beam 401. Each of the crossbeams 404 has a photovoltaic bracket connector 405 at both ends.

[0038] Understandably, during use, the detachable connection between the lifting beam and the movable column can effectively reduce the overall size, facilitating land or water transportation. Furthermore, upon arrival at the work site, precise repositioning and tightening can be achieved using only conventional tools, ensuring the reliability and rigidity of the structural connection. The upper middle part of the crossbeam 404 is fixed to the slider 403, and its horizontal projection is perpendicular to the lifting beam 401, forming a cross-shaped layout that effectively expands the support span. Each crossbeam 404 has photovoltaic bracket connectors 405 at both ends for quick connection and fixation of the photovoltaic bracket 5, allowing for flexible adjustment of the distance between the two crossbeams 404 according to the bracket size, enabling compatible installation of brackets of various specifications.

[0039] It should be noted that, in this embodiment, the photovoltaic bracket connector 405 includes: a steel wire rope 405a and a photovoltaic bracket hook 405b; the steel wire rope 405a connects the crossbeam 404 and the photovoltaic bracket hook 405b respectively, and the two photovoltaic bracket hooks 405b under each crossbeam 404 are at the same height, and the photovoltaic bracket hooks 405b under the two crossbeams 404 are provided with a certain height difference according to the tilt angle of the photovoltaic bracket 5; the photovoltaic bracket hook 405b is provided with a C-shaped groove on the side facing the photovoltaic bracket 5.

[0041] Understandably, through the above design, the rigidity and vibration resistance of the hoisting component 4 in the dynamic environment of water are enhanced during use. It also ensures the positioning accuracy and consistency of repetitive operations when installing the photovoltaic bracket 5, taking into account both ease of operation and structural reliability, and significantly improving the safety and efficiency of waterborne photovoltaic construction.

[0042] Furthermore, the auxiliary equipment also includes a controller and two sets of lithium battery packs; The two sets of lithium battery packs are respectively located at the middle of the upper end of the two floats 1 (not shown in the figure).

The wireless processing module is used to receive the integrated control commands and parse them into thrust control signals, speed and steering control signals, and send the thrust control signals to the control motor driver and the speed and steering control signals to the waterproof motor driver, respectively, so as to coordinate the control of the operating status of the control motor 302f and the waterproof motor 202.

[0043] Understandably, during use, the two sets of lithium battery packs are respectively located at the upper middle part of the two floats 1, providing power to the actuators in their respective areas nearby, effectively balancing the center of gravity of the whole machine and reducing power transmission losses over long distances; the waterproof motor driver and control motor driver built into each set of lithium battery packs are electrically connected to the waterproof motor 202 and control motor 302f on the corresponding float 1, respectively, to achieve localized power drive; its matching wireless calculation module is responsible for receiving comprehensive control commands from the controller and parsing them in real time into thrust control signals for vertical adjustment and speed and steering control signals for navigation, which are then sent to the corresponding drivers; in addition, the controller is installed on any fixed column 302a, which facilitates intuitive monitoring and intervention by the operator, and communicates with the two wireless calculation modules simultaneously via wireless means, completely eliminating the bottleneck of cross-body wiring and realizing synchronous and coordinated control of the dual float system.

[0044] In an optional embodiment, the lithium battery pack is housed in a waterproof enclosure, thereby completely isolating it from moisture, splashes, and corrosive environments, significantly extending battery life and eliminating the risk of short circuits.
