It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0045] It should be noted that the diagrams provided in the embodiments of the present application only schematically illustrate the basic concept of the present application, and therefore only the components related to the present application are shown in the diagrams, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component when actually implemented can be arbitrarily changed, and the layout pattern of the components can also be more complex.

[0046] In the present application, it also needs to be explained that, as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, as the terms "first", "second" appear, they are only for description and differentiation purposes, and cannot be understood as indicating or implying relative importance.

[0047] The present application proposes a large offshore photovoltaic module support float-over installation system for transferring and installing photovoltaic module supports 200, the photovoltaic module supports 200 comprising photovoltaic panels 201, steel truss structures 202, load-bearing beams 203 and spurs 204, wherein the steel truss structures 202 have the photovoltaic panels 201 installed at the upper ends and are connected to the load-bearing beams 203 at the lower ends, the steel truss structures 202 serve as main support frames, the load-bearing beams 203 have greater span and higher strength for interfacing with the float-over installation system, and the spurs 204 are installed below the load-bearing beams 203 for interfacing with pile legs 300.

[0048] The float-over installation system comprises a single barge 10, a chassis trailer device 20 and a hydraulic support device 30. The deck of the single barge 10 is provided with longitudinal sliding rails 11 which can interface with the sliding rails on the wharf. The chassis trailer device 20 is used to quickly and conveniently transfer the photovoltaic module supports 200 to the predetermined position, as shown in Figure 6 The chassis trailer device 20 comprises longitudinally distributed longitudinal beams 21, transverse stabilizing trusses 22 fixed between the longitudinal beams 21, cross beams 23 installed on the longitudinal beams 21 and movable along the longitudinal beams 21, and all-terrain load-bearing rollers 25 installed below the longitudinal beams 21, the longitudinal beams 21 are arranged one-to-one with the longitudinal sliding rails 11, the all-terrain load-bearing rollers 25 can slide along the longitudinal sliding rails 11, and the cross beams 23 can move longitudinally respectively to adjust the spacing to adapt to different photovoltaic panels 201. As Figures 4-5As shown, the hydraulic support device 30 is installed on the cross beam 23, and is symmetrically distributed about the ship's centerplane, each group of hydraulic support device 30 includes a main support hydraulic rod 31, an auxiliary support hydraulic rod 32 and a hinged plate 35; the bottom of the main support hydraulic rod 31 is installed on the cross beam 23 through the hinged base 34, and the top is provided with a plug 33 for installing the load-bearing beam 203 of the photovoltaic module support 200; the bottom of the auxiliary support hydraulic rod 32 is installed on the cross beam 23 through the hinged base 34, and the top is connected to the middle part of the main support hydraulic rod 31 through the hinged plate 35, and the auxiliary support hydraulic rod 32 is used to adjust the angle of the main support hydraulic rod 31. The length and strength of the main support hydraulic rod 31 are greater than those of the auxiliary support hydraulic rod 32. The main support hydraulic rod 31 in the middle of the barge mainly plays a load-bearing role, as its inclination angle is close to the vertical plane and the elongation is small, so the bending moment it bears is small, and the pressure it can bear is larger; the main support hydraulic rod 31 on both sides of the barge has a large elongation of the hydraulic rod and a large inclination angle, so the limit value of the bending moment it bears is small, and at the same time, due to the large inclination angle, it plays a role in limiting the movement of the photovoltaic module support 200. The auxiliary support hydraulic rod 32 only bears axial pressure, and its main role is to adjust the inclination angle of the main support hydraulic rod 31, so the length is set to increase the range of the active angle of the main support hydraulic rod 31 as much as possible under the premise of meeting the structural load, and at the same time, during loading and unloading, it and the main support hydraulic rod 31 can be adjusted to the appropriate position to make the barge smoothly unload.

The load-bearing roller 25 is installed at the bottom of the longitudinal beam 21 and can rotate 360 degrees, and the power and control equipment is installed on the longitudinal beam 21 and the transverse stabilizing truss 22 and does not affect the movement of the cross beam 23, and can be remotely controlled.

The first rolling bearing 241 is driven by a motor to realize the movement of the cross beam 23 along the longitudinal beam 21, and the cross beam 23 is provided with a brake device to fix the position of the cross beam 23.

[0051] Further optimization, the longitudinal slide rail 11 is provided with a limiting block 12 at the front end of the bow direction, so as to avoid the chassis trailer device 20 from moving out of the longitudinal slide rail 11, and the limiting block 12 is provided with a rubber buffer pad on the surface in contact with the longitudinal beam 21, so as to play a buffering role.

[0052] Further optimization, the main support hydraulic rod 31 and the auxiliary support hydraulic rod 32 in the hydraulic support device 30 are independently controlled, so as to adapt to the support of photovoltaic module racks 200 of different structural types (such as inclined type or horizontal type).

[0053] Further optimization, the plug 33 is detachably installed at the top end of the main support hydraulic rod 31, so as to be convenient for replacement to adapt to the load-bearing beams 203 of different shapes and sizes. Figure 8 As shown in the figure, the plug 33 is U-shaped in the embodiment, the depth of the slot is greater than the diameter of the load-bearing beam 203, the surface of the plug 33 in contact with the load-bearing beam 203 is provided with an elongated rod type second rolling bearing 331, so as to reduce the friction force when the U-shaped plug 33 and the load-bearing beam 203 relatively rotate. The load-bearing beam 203 of the photovoltaic module rack 200 has greater strength and toughness compared with the beam unit of the steel truss structure 202, is subjected to strengthening treatment at the position in contact with the U-shaped plug 33, and is subjected to polishing and lubricating treatment to reduce the friction between the U-shaped plug 33 and the load-bearing beam 203.

[0054] Further optimization, the power positioning system 14 of the single barge 10 includes a bow propulsion device, a stern propulsion device, a stern side propulsion device and a middle side propulsion device, the propulsion devices at different positions are symmetrically arranged about the longitudinal section of the ship body, and the propulsion devices at different positions are independently controlled, so as to realize automatic adjustment of the position of the single barge 10.

[0055] Further optimization, the transverse fender 13 is installed on the left and right sides of the single barge 10, and the position of the transverse fender 13 is higher than the power positioning system 14 and can prevent the pile leg from colliding with the power positioning system 14.

[0056] Correspondingly, the application further provides a large-scale offshore photovoltaic module rack floating installation method, which adopts the floating installation system and includes the following steps:

[0057] The monomer barge 10 is driven into the dock, the longitudinal slide rails 11 on the hull deck are aligned with the longitudinal slide rails 11 of the dock, the chassis trailer device 20 is moved to a suitable position under the photovoltaic module support, the position of the cross beam 23 is adjusted so that the U-shaped plug at the top of the main support hydraulic rod on the cross beam 23 is aligned with the load-bearing beam 203 of the photovoltaic module support, then the main support hydraulic rod and the auxiliary support hydraulic rod 31 are adjusted to make the plug 33 fork the load-bearing beam 203, then the main support hydraulic rod and the auxiliary support hydraulic rod 31 are operated to lift the photovoltaic module support, the omnibearing load-bearing roller 25 is driven to move, the chassis trailer device 20 drives the photovoltaic module support 200 to be transferred from the longitudinal slide rails 11 of the dock to the longitudinal slide rails 11 of the monomer barge 10, and when the front end of the longitudinal beam 21 is in contact with the limiting block 12, the photovoltaic module support is fixed by binding.

[0058] The monomer barge 10 is driven to the designated installation position, the three degrees of freedom directions of fine bowing, yawing and pitching are adjusted through the power positioning system 14, the three degrees of freedom directions of fine yawing, heaving and rolling are adjusted through the hydraulic support device 30, when the plug 204 is aligned with the pile leg 300, the hydraulic support device 30 is adjusted to realize load transfer, all the hydraulic rods are retracted, the monomer barge 10 is retreated through the power positioning system 14, and the whole photovoltaic module support 200 installation process is completed.

If there is a positional error between the slot of the U-shaped plug 33 and the load-bearing beam 203 during the docking process, the U-shaped plug 33 can be adjusted in position by the universal load-bearing roller 25 and the hydraulic support device 30 to dock. At the same time, each group of main support hydraulic rods 31 and auxiliary support hydraulic rods 32 is independently controlled, and the real-time monitoring and adjustment of the hydraulic rods are realized according to the feedback of the pressure sensing device on the hydraulic rod to the control program, so as to realize the reasonable distribution of the load of the photovoltaic module support 200 on the hydraulic support device 30. Then the photovoltaic module support 200 is lifted, the cross beam 23 is fixed, the chassis trailer device 20 is transferred to the deck of the single barge 10 until the longitudinal beam 21 and the limiting block 12 are in contact, and the chassis trailer device 20 is bound and fixed to complete the loading. In this case, the insertion tip 204 of the photovoltaic module support 200 is in the vertical direction, and the hydraulic support device 30 only needs to adjust the hydraulic rod to realize the vertical and horizontal movement of the photovoltaic module support 200 to complete the loading, transportation and installation. In another case, the insertion tip 204 of the photovoltaic module support 200 is in the inclined direction, and the hydraulic support device 30 needs to additionally adjust the roll angle of the photovoltaic module support 200 until the insertion tip 204 is in the vertical direction, and then load, transport and install. The height of the photovoltaic module support 200 in all cases can ensure that the chassis trailer device 20 and the hydraulic support device 30 smoothly enter the predetermined position below the photovoltaic module support 200. The side wall of the wharf 400 is provided with a wharf fender 403.

[0061] Figure 3 is the state diagram of the insertion tip 204 and the pile leg 300 docking after the inclined photovoltaic module support 200 shown in the first embodiment of the present application is loaded to the installation position. At this time, the brake device of the universal load-bearing roller 25 and the cross beam 23 is in the locked state, the longitudinal slide rail 11 on the deck is used to limit the yawing and rolling movement of the universal load-bearing roller 25, the limiting block 12 at the bow direction of the longitudinal slide rail 11 is in close contact with the longitudinal beam 21 to limit the longitudinal movement of the chassis trailer device 20, and the chassis trailer device 20 is bound to ensure its stability during installation. The cross beam 23 and the support rib plate 24 are an integral whole, the cross beam 23 can slide on the longitudinal beam 21 through the first rolling bearing 241, the first rolling bearing 241 on both sides of the longitudinal beam 21 is a driving bearing, and the driving bearing and the brake device of the cross beam 23 are controlled by the power and remote control device located on the cross beam 23, and at the same time the cross beam 23 can be installed and detached. Figure 3The case shown is that the inclined photovoltaic module support 200 is connected to different height pile legs 300, at this time the plurality of insertion tips 204 fixed on the photovoltaic module support 200 are short in length, another installation case of the inclined photovoltaic module support 200 is that the pile legs 300 are of the same height, at this time the plurality of insertion tips 204 fixed on the photovoltaic module support 200 are long in length, and the installation process and Figure 3 are the same as shown.

[0062] Figure 9 and Figure 10 is a state diagram of the horizontal photovoltaic module support 200 of the second embodiment of the present application after reaching the installation position, the single barge 10 reaches the predetermined installation position between the pile legs 300 through the power positioning system 14, the horizontal photovoltaic module support 200 is slowly lowered through the system regulation of the hydraulic support device 30, if the insertion tips 204 and the pile legs 300 are not aligned during the connection process, the adjustment in the three degrees of freedom directions of the yaw, pitch and roll can be realized through the hydraulic support device 30, the adjustment in the three degrees of freedom directions of the yaw, pitch and roll can be realized through the power positioning system 14 (at this time the crossbeam 23 is bound and fixed and cannot slide). After the load transfer of the horizontal photovoltaic module support 200 is completed, the hydraulic support device 30 is retracted, the positions of the main support hydraulic rod 31 and the auxiliary support hydraulic rod 32 are adjusted, and the barge is withdrawn.
