Technical Field

[0001] This utility model relates to the field of marine photovoltaic system technology, and in particular to a cable management device for marine photovoltaic construction. Background Technology

[0002] Offshore photovoltaic (PV) connection cables are a crucial component of offshore PV systems. Their primary function is to transmit the electricity generated by the offshore PV modules to land or other power-consuming locations. The offshore PV modules convert solar energy into direct current (DC), which is then converted into alternating current (AC) by an inverter and transmitted via the connection cables to offshore or onshore substations. Cable assembly typically requires multiple cables to be installed simultaneously. When dragging the cables, specialized personnel are needed to remove them from the cable reel, which is time-consuming, labor-intensive, and prone to tangling and cross-linking.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1-2 As shown, a cable management device for offshore photovoltaic construction includes a cable management platform 1, a fixing frame 5, and multiple sets of cable management units, wherein:

[0030] The fixing frame 5 is fixed on the cable management platform 1. Each cable management unit includes a rotating rod 3 and a pulley 6. The rotating rod 3 includes a vertical rod 3-1 and a horizontal rod 3-2, which are integrally formed. The vertical rod 3-1 can be inserted into the central cylinder of the cable shaft 2. The length of the horizontal rod 3-2 is greater than the diameter of the cable shaft 2. The end of the horizontal rod 3-2 is fixed with a positioning ring 4 for the cable to pass through. The top of the pulley 6 is rotatably connected to the fixing frame 5 through a rotating component 7. This provides more room for movement when dragging the cable. The pulley 6 rotates with the dragging direction to ensure that the cable passes smoothly through the pulley 6 and avoids jamming.

[0031] like Figure 3 As shown, the rotating component 7 includes a first ring 7-1 fixed below the fixing frame 5 and a second ring 7-2 fixed on the top of the pulley 6. The second ring 7-2 is perpendicular to the slide rail on the pulley 6. The first ring 7-1 and the second ring 7-2 are perpendicular to each other. The first ring 7-1 and the second ring 7-2 are connected to form a double-ring structure, so that the pulley 6 can rotate in both the horizontal and vertical planes, so that multiple cables from different directions can be smoothly gathered together without getting stuck.

[0032] In use, place the cable spool 2 with the cable wound on it on the cable management platform 1, insert the upright 3-1 of the rotating rod 3 into the central cylinder of the cable spool 2, remove one end of the cable from the cable spool 2, pass it through the positioning ring 4, and then around the pulley 6. When the worker drags the cable, the cable spreads out around the cable spool 2. During the spreading process, the rotating rod 3 rotates along with the spreading cable, which plays the role of managing the cable. At the same time, the setting of the pulley 6 makes the whole dragging process time-saving and labor-saving.

[0033] Example 2

[0034] This embodiment is a further detailed description based on Embodiment 1.

[0035] like Figure 1As shown, the cable management platform 1 is equipped with two to six sets of cable management units. The number of sets of units can be selected based on the number of cables required for the offshore photovoltaic system, making it widely applicable. Workers can simultaneously remove six cables from the cable reel 2 and drag them to the offshore photovoltaic system without the cables becoming tangled.

[0036] Preferably, the fixing frame 5 includes a portal frame 5-1 fixed to opposite sides of the cable management platform 1 and a crossbeam 5-2 fixed between the two portal frames 5-1. The top of the pulley 6 is rotatably connected to the crossbeam 5-2 through a rotating component 7. This structure of the fixing frame 5 has high structural stability.

[0037] Preferably, the cable management unit has six groups, and the six groups of cable management units are arranged in two rows, with three cable management units in each row, and three pulleys 6 on each crossbeam 5-2.

[0038] Preferably, the cable management platform 1 is equipped with guardrails (not shown in the figure) around its four edges to prevent workers from falling off the cable management platform 1 during auxiliary operations.

[0039] Example 3

[0040] This embodiment is a further limitation based on embodiment 1 or 2.

[0041] Preferably, the intersection of the upright 3-1 and the crossbar 3-2 is rounded, which can provide good support and ensure smooth rotation, making the movement more flexible.

[0042] Preferably, the rotating rod 3 is made of PVC or aluminum alloy, which has both strength and deformation capacity, thus extending its service life.

[0043] Preferably, the length of the upright 3-1 is 2 / 3 of the height of the cable shaft, which can ensure that the upright 3-1 will not come out of the cable shaft 2 during the process of pulling back the cable.

[0044] Preferably, the included angle between the upright 3-1 and the crossbar 3-2 is 60~85°, which ensures that the crossbar 3-2 has a certain downward tilt angle, so as to press down the cable.

[0045] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0046] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
