DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The photovoltaic power collection line collecting device, as shown in Figure 1 , comprises connecting rods 1, longitudinal plates 2, wire tubes 3, pullers 4 and locking rods 5. The two connecting rods 1 are fixed on the support of the photovoltaic module by bolts. The two longitudinal plates 2 are fixedly connected between the two parallel connecting rods 1 at intervals. The wire tubes 3 are adhered on the longitudinal plates 2 at intervals and in parallel. The puller 4 is slidingly connected in the wire tube 3 to pull the cable of the photovoltaic module into the wire tube 3. The locking rod 5 is connected with the longitudinal plate 2 to press the wire tube 3 towards the longitudinal plate 2.

[0027] In combination with Figure 1 , Figure 4 , the connecting rod 1 is a grooved square tube. A bolt pair is slidingly connected in the groove to fix the connecting rod 1 on the support of the photovoltaic module. Two semi-open clamping blocks 11 are fixedly connected on the connecting rod 1 at intervals. The open end of the clamping block 11 is a circular groove. The puller 4 can be clamped on the clamping block 11 to serve as a storage for the puller 4. The longitudinal plate 2 is a strip-shaped plate. The longitudinal plate 2 is connected with the connecting rod 1 by welding. A boss is welded on the longitudinal plate 2. A plurality of arc-shaped lower circular grooves 21 are provided on the boss at intervals. The radius of the lower circular groove 21 is the same as the outer diameter of the wire tube 3. The wire tube 3 is embedded in the lower circular groove 21 to facilitate the arrangement, positioning and installation of the wire tube 3.

[0028] In combination with Figure 1 , Figure 2The conduit 3 is a plastic cylindrical tube, and its length is adapted to the mountainous environment and the distribution of photovoltaic modules. A long, narrow groove 31 is provided on one side of the conduit 3, with the groove 31 being half the length of the conduit 3. Several identification holes 32 are spaced apart at the end of the conduit 3 away from the groove 31. These identification holes 32 are all blind holes and are coated with watercolor. Connectors 7 are attached to both ends of the conduit 3, and cables also pass through the connectors 7. A connector 71 is fixedly connected to the end of the connector 7 where it connects to the conduit 3. The inner diameter of the connector 71 is the same as the outer diameter of both the conduit 3 and the connector 7. The connector 71 is fitted over the ends of the conduit 3 and the connector 7 to connect them and prevent the cables from being exposed.

[0029] Combination Figure 1 , Figure 2 The cable puller 4 includes a flexible rod 41, a cable reel 42, and a handle 43. The flexible rod 41 is a cylindrical rod with a length greater than half the length of the cable tube 3. The cable reel 42 has a multi-layered disc structure, and its outer diameter is larger than that of the flexible rod 41. The cable reel 42 is fixed to one end of the flexible rod 41 that extends out of the cable tube 3. The handle 43 has a sheet-like structure and is fixed to the other end of the flexible rod 41. The handle 43 passes through a groove 31 to extend out of the cable tube 3.

[0030] Before installation, use watercolor pen colors to represent the horizontal coordinates according to the array distribution of the photovoltaic modules, and place different numbers of watercolor dots in the identification holes 32 to represent the vertical coordinates. During installation, first thread the cable into the connector 7 directly below each photovoltaic module. When it extends to the connecting rod 1, thread the cable puller 4 into the conduit 3, then tie the cable to the reel 42. Next, pull the handle 43 to pull the cable from one end of the conduit 3 to the other end, while the connector 71 is about to be put onto the conduit 3 to fix the conduit 3 and the connector 7. After using the cable puller 4, it can be slid out of the conduit 3 and embedded in the clamp 11 to prevent the cable puller 4 from being lost when threading into other conduits 3. The cable puller 4 can also be threaded into the connector 7 to facilitate cable threading.

[0031] Combination Figure 3 , Figure 4 The locking rod 5 is a long, strip-shaped member. Several semi-circular upper grooves 51 are spaced apart at the bottom of the locking rod 5. The radii of the lower grooves 21 and the upper grooves 51 are the same as the outer radius of the conduit 3. The conduit 3 is embedded within the lower grooves 21 and the upper grooves 51. A bolt 6 passes through the middle of the locking rod 5, and a nut 61 is fixedly connected to the longitudinal plate 2. The bolt 6 passes through the locking rod 5 and the longitudinal plate 2 and is threadedly connected to the nut 61, so that the locking rod 5 and the longitudinal plate 2 clamp multiple conduits 3.

[0032] When the plurality of line pipes 3 on the columnar plate 2 are all inserted into the cable, a small amount of glass glue is applied in the lower circular groove 21, and then the corresponding line pipe 3 is inserted into the lower circular groove 21 from top to bottom according to the mark on the identification hole 32, and the line pipe 3 is preliminarily fixed by the viscosity of the glass glue. After all the line pipes 3 are placed in the lower circular groove 21, the locking rod 5 is placed on the line pipe 3 and the bolt 6 is screwed with the nut 61, so that the line pipe 3 is stably fixed under the clamping of the locking rod 5 and the longitudinal plate 2. Finally, the connector 71 is sleeved on the other end of the cable and is sleeved with the line pipe 3 at the sliding groove 31, which is convenient for butt joint with other connecting pipes 7. The exposed sliding groove 31 is relatively narrow, which not only can avoid the entry of sand and dust, but also can play a heat dissipation effect.

[0033] In summary, the utility model can not only straighten the cable, but also protect the cable itself, thereby prolonging the service life of the cable. After the photovoltaic module fails, the line pipe 3 and the connecting pipe 7 corresponding to the problematic photovoltaic module can be easily distinguished, and only the line pipe 3 and the connecting pipe 7 need to be removed during replacement. The connector 71 can not be glued to the line pipe 3 and the connecting pipe 7, which facilitates subsequent insertion of the replaced cable.

[0034] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the utility model embodiments.
