The carrier plate 30 is used to place in the groove body 10 to carry the cable, and the cross beam 20 is used to lift the carrier plate 30, and the cross beam 20 is also used to interface with the external connecting piece to realize the fixed installation of the bridge.
[0045] In the following, the heat dissipation type cable bridge 100 is further described in combination with Figures 1 to 9 .
[0046] As shown in Figure 3 and Figure 6 , in the present embodiment, the width direction cross section of the trough body 10 is U-shaped. The middle section of the trough body 10 is provided with two through holes 11 respectively on both sides, and the connecting line of the two through holes 11 is consistent with the width direction of the trough body 10. The upper end of both sides of the trough body 10 is provided with a plurality of first heat dissipation holes 12 which are sequentially distributed along the length direction of the trough body 10.
[0047] As shown in Figure 5 and Figure 7 , in the present embodiment, the crossbeam 20 is in a straight line type and penetrates through the through hole 11 along the width direction of the trough body 10. Both ends of the crossbeam 20 extend to the outside of the trough body 10 and are provided with lifting holes 21. When it is necessary to hoist the cable bridge under the building (such as under the bridge bottom, under the ceiling of the indoor, etc.), the lifting hole 21 is connected with the steel rope or the lifting rod. In addition, when it is necessary to install the cable bridge vertically close to the wall, the crossbeam 20 can be locked on the wall by the way of screw or expansion screw through the lifting hole 21. The crossbeam 20 is a hollow pipe body, and a plurality of second heat dissipation holes 22 are formed on both sides of the crossbeam 20 and are sequentially distributed along the width direction of the trough body 10.
[0048] As shown in Figure 4 , the carrier plate 30 is arranged on the crossbeam 20 to form an overhead layer between the carrier plate 30 and the bottom of the trough body 10. As shown in Figure 8 , the load bearing surface of the carrier plate 30 is provided with a plurality of uniformly distributed third heat dissipation holes 31.
[0049] As shown in Figure 8 and Figure 9 , both sides of the carrier plate 30 are provided with downwardly bent support portions 32.

The support portion 32 can provide auxiliary support for the carrier plate 30, reducing the risk of the two ends of the carrier plate 30 being crushed by the cable.
[0050] In addition, considering that in actual use scenarios, a plurality of cable bridges need to be connected together, and expansion joints need to be installed between adjacent two cable bridges. Combined with Figure 1 and Figure 8 , both sides of the two ends of the carrier plate 30 are provided with notched portions 33. As shown in Figure 8 , both sides of the two ends of the trough body 10 are provided with second connecting holes 14, for example, in the present embodiment, the second connecting hole 14 is a vertically arranged waist hole. The position of the second connecting hole 14 is opposite to the notched portion 33. The second connecting hole 14 is used to connect the expansion joint. The notched portion 33 can provide space for the installation of the expansion joint, reducing the installation difficulty. In addition, as shown in Figure 8 , in the present embodiment, the two ends of the trough body 10 are also provided with circular grounding holes 15, which are used to connect the grounding wire.
[0051] Combination Figure 2 and 5 As shown, the cover plate 40 is located at the top of the tank 10, and the cover plate 40 has an extension portion 41 on both sides. The extension portion 41 is located outside the first heat dissipation hole 12 to form a lateral baffle structure, and an movable gap is reserved between the inner side of the extension portion 41 and the first heat dissipation hole 12.
[0052] like Figure 5 As shown, the middle region of the cross-section of the cover plate 40 along the width direction of the tank 10 is an upward-arched angled structure or an arc-shaped structure. The upward-arched angled structure or arc-shaped structure can use gravity to discharge liquids or debris that fall on the cover plate 40 to both sides.
[0053] like Figure 5 and Figure 6 As shown, in this embodiment, the top ends of both sides of the groove 10 are provided with bent portions 13. The bent portions 13 abut against the sides of the cover plate 40 to support the cover plate 40. The bent portions 13 can provide stable support for the cover plate 40.
[0054] Furthermore, such as Figure 5 As shown, the outer side of the bent portion 13 abuts against the inner side of the extension portion 41. A sliding relationship can be formed between the bent portion 13 and the extension portion 41, which facilitates assembly and disassembly.
[0055] like Figure 6 As shown, the bent portion 13 is provided with a threaded hole 131, and the cover plate 40 is provided with a first connecting hole 42. The cover plate 40 is secured to the bent portion 13 by screws 50 passing through the first connecting hole 42 and the threaded hole 131. The screws 50 can be used to secure the cover plate 40 and the groove 10, improving the connection stability.
[0056] Brief description of working principle:
[0057] Combination Figures 3 to 5 As shown, during assembly, the crossbeam 20 is first inserted laterally into the through hole 11 of the tank 10 from the outside of one side. Next, the carrier plate 30 is placed into the tank 10 and placed on the crossbeam 20. Finally, the cover plate 40 is placed on top of the tank 10.
[0058] In use, the cable is laid on the carrier plate 30. See also... Figure 4 and Figure 5Since the cross beam 20 is a hollow tube, the two ends of the cross beam 20 can be used as ports for communicating with the outside. Meanwhile, the inner cavity of the cross beam 20 is in communication with the inner cavity of the groove body 10 through the second heat dissipation hole 22 and the third heat dissipation hole 31, so that the heat generated by the cable during operation can be quickly dissipated outward through the first heat dissipation hole 12 and the cross beam 20, and the airflow from the outside can also circulate in the groove body 10, which can also improve the heat dissipation efficiency. Moreover, the outer extension part 41 of the cover plate 40 and the cross beam 20 can block the dust, liquid and debris from the outside, which can improve the heat dissipation efficiency and protect the cable at the same time. In addition, the cable is arranged in the inner cavity of the groove body 10 through the carrier plate 30, which provides sufficient heat dissipation space above and below the cable, and is beneficial to improve the heat dissipation efficiency.
[0059] In order to reduce the risk of dust and debris invading the inner cavity of the groove body 10 from the first heat dissipation hole 12 and the cross beam 20, in some embodiments, the heat dissipation type cable bridge 20 can further comprise a first filter screen and a second filter screen. The first filter screen is attached to the side wall of the groove body 20 and covers the first heat dissipation hole 12. The second filter screen is arranged at the ports at the two ends of the cross beam 20.
[0060] In addition, based on the requirements of heat dissipation and structural stability, in the present scheme, the groove body 10, the carrier plate 30, the cross beam 20 and the cover plate 40 are preferably made of a galvanized sheet structure.
[0061] The heat dissipation type cable bridge 100 described above utilizes the groove body 10, the cross beam 20, the carrier plate 30 and the cover plate 40 to form a semi-closed bridge structure, which protects the cable and provides a heat dissipation channel for the cable to communicate with the outside environment, so as to improve the heat dissipation efficiency.
[0062] Embodiment two
[0063] As shown in Figure 10 and Figure 11 , it is another embodiment of the heat dissipation type cable bridge 100 of the present application.
[0064] The difference between the present embodiment and embodiment one is that, as shown in Figure 10 and Figure 11 , in the present embodiment, the number of carrier plates 30 is multiple and stacked together from top to bottom. As shown in Figure 11 , the carrier plate 30 at the bottom is connected with the cross beam 20, and the other carrier plates 30 are stacked together in the vertical direction. The multiple carrier plates 30 arranged in layers can form a multi-layer storage structure, which is convenient for layered wiring of the cables in the groove body 10, can realize vertical classification wiring to reduce the difficulty of wiring, or can make the spacing between the cables larger to improve the heat dissipation efficiency.
[0065] Further, in other embodiments, in order to let the carrier plates 30 can be fixed with each other, the carrier plates 30 can also be provided with detachable pins or bolts, and the relative fixation between the two carrier plates 30 adjacent to each other in the lateral direction is realized by the pins or bolts.
[0066] The other structures of the embodiment are the same as those of the first embodiment, and the beneficial effects of the first embodiment can also be achieved.
[0067] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the description.
[0068] The above embodiments only express the preferred implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
