[0032] like Figure 1 , 2 As shown, Figure 1 This is a structural schematic diagram of an exemplary embodiment of the cable laying and fixing system in the offshore photovoltaic field disclosed in the present invention. Figure 2 for Figure 1 A side view of the cable laying and fixing system in an offshore photovoltaic field is shown.

[0033] The cable laying and fixing system in the offshore photovoltaic field area includes: a box-type transformer support platform 1, a first cable climbing frame 2, an operation and maintenance channel 3, and a second cable climbing frame. The box-type transformer support platform 1 is used to support the box-type transformer substation; the first cable climbing frame 2 is fixed on the box-type transformer support platform 1, the first cable climbing frame 2 extends in the vertical direction, and the first cable climbing frame 2 is used to support the cable; the operation and maintenance channel 3 is fixed on the grid, and the operation and maintenance channel 3 forms a pedestrian channel; the second cable climbing frame 4 is fixed on the operation and maintenance channel 3, the second cable climbing frame 4 extends in the vertical direction, and the second cable climbing frame 4 is used to support the cable; wherein, the first cable climbing frame 2 and the second cable climbing frame 4 are arranged at intervals in the vertical direction Y.

[0034] In the cable laying and fixing system in the offshore photovoltaic field provided by this exemplary embodiment, the cables on the operation and maintenance channel 3 can pass through the first cable climbing frame 2, the second cable climbing frame 4, and the box-type transformer support platform 1 in sequence, so as to be connected to the box-type substation. The first cable climbing frame 2 and the second cable climbing frame 4 can support and fix the cables, thereby achieving stable routing of the cables. At the same time, this exemplary embodiment fixes the first cable climbing frame 2 and the box-type transformer support platform 1, and fixes the second cable climbing frame 4 and the operation and maintenance channel 3. This setting can reduce the length of a single cable climbing frame, thereby increasing the strength of a single cable climbing frame, reducing the weight of a single cable climbing frame, and facilitating the installation and maintenance of a single cable climbing frame.

[0035] In this exemplary embodiment, Figure 1 , 2As shown, in the vertical direction Y, the first cable rack 2 and the second cable rack 4 are spaced apart on the same straight line. The cables fixed on the first cable rack 2 and the second cable rack 4 extend in the vertical direction. This arrangement can prevent the cables from turning laterally between the first cable rack 2 and the second cable rack 4, thereby reducing the probability of damage caused by horizontal and vertical bending of the cables.

[0036] In this exemplary embodiment, Figure 1 , 2 As shown, in the vertical direction Y, the spacing distance between the first cable climbing frame 2 and the second cable climbing frame 4 is S3, the size of the first cable climbing frame 2 in the vertical direction is S1, and S3 / S1 is greater than or equal to 1 / 15 and less than or equal to 1 / 5. S3 / S1 can be equal to 1 / 15, 2 / 15, 3 / 15, etc. If S3 / S1 is too large, S3 is too large, the cable hanging length is too long, and the cable is easily damaged. If S3 / S1 is too small, S3 is too small, the first cable climbing frame 2 and the second cable climbing frame 4 are prone to interference. This exemplary embodiment sets S3 / S1 to an appropriate size, which can not only avoid mutual interference between the first cable climbing frame 2 and the second cable climbing frame 4, but also reduce the risk of cable damage.

[0037] In this exemplary embodiment, Figure 1 , 2 As shown, the vertical dimension of the first cable climbing frame 2 is S1, and the vertical dimension of the second cable climbing frame 4 is S2, and S1 / S2 is greater than or equal to 0.8 and less than or equal to 1.2. For example, S1 / S2 can be equal to 0.8, 0.9, 1, 1.1, 1.2, etc. In this exemplary embodiment, the first cable climbing frame 2 and the second cable climbing frame 4 are set to be of similar lengths, which can prevent the length of one of the first cable climbing frame 2 and the second cable climbing frame 4 from being too long and the length of the other from being too short, thereby ensuring the strength of the first cable climbing frame 2 and the second cable climbing frame 4.

[0038] In this exemplary embodiment, Figure 1 , 2 As shown, the first cable climbing frame 2 can be welded to the box-type transformer support platform 1, and the second cable climbing frame 4 can be welded to the operation and maintenance channel 3. It should be understood that in other exemplary embodiments, the first cable climbing frame 2 and the box-type transformer support platform 1 can be fixedly connected in other ways, and the second cable climbing frame 4 and the operation and maintenance channel 3 can also be fixedly connected in other ways. For example, the first cable climbing frame 2 and the box-type transformer support platform 1 can be fixedly connected by bolts or the like, and the second cable climbing frame 4 and the operation and maintenance channel 3 can also be fixedly connected by bolts or the like.

[0039] In this exemplary embodiment, Figure 1 , 2As shown, the first cable climbing frame 2 is fixed to the corner position of the box-type transformer support platform 1. This arrangement can prevent the first cable climbing frame 2 from affecting the placement of the box-type transformer substation.

[0040] In this exemplary embodiment, Figure 1 , 2 As shown, the box-type transformer support platform 1 includes a first support bottom 11, and the first cable climbing frame 2 is fixed on the first support bottom 11. The first support bottom 11 has a relatively stable structure, and this arrangement can ensure the stability of the first cable climbing frame 2.

[0041] In this exemplary embodiment, Figure 1 , 2 As shown, the operation and maintenance channel 3 includes a second support bottom 32, and the second cable climbing frame 4 is fixed on the second support bottom 32. The second support bottom 32 has a relatively stable structure, and this arrangement can ensure the stability of the second cable climbing frame 4.

[0042] In this exemplary embodiment, Figure 1 , 2 As shown, the cable laying and fixing system in the offshore photovoltaic field area also includes: pile foundation 5, the pile foundation 5 is fixed on the sea surface, and the pile foundation 5 is used to support the box-type transformer support platform 1. There can be multiple pile foundations 5, for example, there can be 4 pile foundations 5, and the 4 pile foundations 5 are fixed at the four corners of the box-type transformer support platform 1.

[0043] In this exemplary embodiment, Figure 1 , 2 The first cable climbing frame 2 includes a first main rod body 21, and the second cable climbing frame 4 includes a second main rod body 42; the first main rod body 21 and the second main rod body 42 both extend in the vertical direction, and the first main rod body 21 and / or the second main rod body 42 are hollow structures. For example, the first main rod body 21 and / or the second main rod body 42 can be a hollow cylindrical structure. The first main rod body 21 and the second main rod body 42 of the hollow structure have a relatively small weight. This setting can not only meet the supporting function of the cable climbing frame for the cable, but also reduce the load of the cable laying and fixing system in the offshore photovoltaic field.

[0044] In this exemplary embodiment, Figure 1 , 2 The box-type transformer support platform 1 and the operation and maintenance channel 3 may be grid structures, and the box-type transformer support platform 1 and the operation and maintenance channel 3 may be composed of a plurality of reinforcing ribs cross-fixed.

[0045] In this exemplary embodiment, Figure 1 , 2The operation and maintenance channel 3 may also include a side rail, the side rail may include a vertical support rib 31, and the vertical support rib 31 may include a first support rib 311 located above the second support bottom 32 and a second support rib 312 located below the second support bottom 32. The operation and maintenance channel 3 may also include a reinforcing bar 33, and the reinforcing bar 33 may be connected between the second support rib 312 and the second support bottom 32. The reinforcing bar 33, the second support bottom 32, and the second support rib 312 may form a triangular structure, and this arrangement may improve the strength of the operation and maintenance channel 3. Among them, the reinforcing bar 33 may be fixed to the midpoint of the second support bottom 32 in the width direction.

Different cable clamps 6 in the same cable clamp group 22 can fix cables respectively, and this arrangement can increase the number of fixed cables on the first cable climbing frame 2. In addition, the cables in the plurality of cable clamps 6 in the same cable clamp group 22 will exert forces on the first main pole body 21 in different directions, and this arrangement can reduce the risk of the first main pole body 21 tipping over.

The cables in the centrally symmetrical cable clamps 6 may balance the center of gravity of the first cable climbing frame 2, so that the center of gravity of the first cable climbing frame 2 is located at the central axis position of the first main pole body 21 or near the central axis, thereby further reducing the risk of tipping over of the first main pole body 21.

[0049] In this exemplary embodiment, the cable clamp 6 includes: an extension rod 61, a first half clamp part 62, and a second half clamp part 63.
