Description

Technical Field

[0001] The utility model belongs to the technical field of cable bridges, and in particular relates to an outdoor cable bridge. Background Art

[0002] Cable trays are commonly used as supporting and protecting devices for laying cables in the power supply system of electrical equipment. They protect and guide the cables laid in the cable trays. Cable trays are mainly divided into trough type, tray type, ladder type, grid type and other structures. In public passages or outdoor crossing road sections, tray type cable trays are usually used. Tray type cable trays have the advantages of light weight, large load, beautiful appearance, simple structure and easy installation.

[0003] There are many types of outdoor cable trays in the prior art. For example, the Chinese utility model patent with application number CN201720894788.4 discloses "an outdoor cable tray". In this scheme, "it includes a cable trough box and a partition cover, the partition cover can be detachably installed on the bottom plate of the cable trough box, a channel for laying a first cable is formed between the partition cover and the bottom plate, a plurality of clamps for clamping and fixing a second cable are arranged at intervals on the top surface of the partition cover, a drainage groove is formed between the side of the partition cover and the side plate of the cable trough box, and a drainage hole is opened on the bottom surface of the drainage groove. The utility model divides the space in the cable trough box into two by arranging a partition cover in the cable trough box, so that two different cables can be laid at the same time. The first cable located in the channel can be effectively prevented from being eroded by dust, rainwater, etc. under the protective effect of the partition cover; the clamps arranged on the top surface of the partition cover can be used to fix the second cable, and when it rains, rainwater can flow into the drainage groove along the side of the partition cover and finally flow out through the drainage hole, so that it is suitable for laying cables that can be used in an open air environment";

[0004] The above solution solves the problem that "on rainy days, rainwater will gather in the cable tray, and the cable will be easily damaged when immersed in water, leading to safety accidents such as leakage and short circuit", and is practical, but the above solution still has inconveniences. The cable will generate heat. Although the above solution has good waterproof function, it is not convenient for the internal cable to ventilate and dissipate heat. Moreover, when multiple cable trays are spliced, the cables in the separation cover cannot be ventilated, and there is a possibility that the cable will overheat and burn out, which needs to be improved.

[0005] Therefore, the utility model provides an outdoor cable bridge to solve the above-mentioned shortcomings. Utility Model Content

[0020] See also Figure 1-Figure 3 The utility model provides the following technical solutions: an outdoor cable bridge, comprising a bridge body 1 and a top plate 2, the top plate 2 is installed on the top of the bridge body 1, main vents 4 are provided on the left and right sides of the bridge body 1, a trapezoidal groove 16 is provided on the inner ground of the bridge body 1, a water outlet 17 is provided in the middle of the bottom of the bridge body 1, and also comprises a water retaining plate 5 and a placement plate 6, both sides of the interior of the bridge body 1 are provided with a slide groove 61, the placement plate 6 is slidably installed in the slide groove 61, the water retaining plate 5 is fixed on the top of the placement plate 6, a secondary vent 14 is provided on the top of the water retaining plate 5, and a heat dissipation port 11 is provided on the placement plate 6, A heat dissipation port 11 is provided on the support plate 51, and a mounting foot 3 is fixed on the top of the top plate 2. During installation, the top plate 2 is first fixed with bolts through the mounting foot 3, and then the bridge frame body 1 can be slidably installed, and the wire is passed through the interlayer between the two partition plates 9. Since the bottom of the placement plate 6 is empty, the air volume will blow from the bottom of the placement plate 6 to the heat dissipation port 11, and will also blow from the main vent 4 to the auxiliary vent 14, thereby ventilating and dissipating heat. If rainwater enters from the main vent 4, it will slide down the water retaining plate 5 to the drain port 15, and then be discharged from the water outlet 17 at the bottom, thereby waterproofing and convenient use.

[0021] Specifically, by Figure 1 and Figure 2It can be seen that in this embodiment, a support plate 51 is fixed in the middle of the water retaining plate 5, and a plurality of equally spaced partition plates 9 are arranged on the top of the placement plate 6 and the support plate 51. A mezzanine is provided between every two partition plates 9. The partition plates 9 can facilitate the separate placement of multiple cables to avoid subsequent cables from being entangled with each other and causing interlacing, thereby affecting subsequent maintenance by staff.

[0022] Specifically, by Figure 1 and Figure 2 It can be seen that in this embodiment, a drain port 15 is opened on the side of the placement plate 6, and the water retaining plate 5 is located between the two drain ports 15. Rainwater is directly discharged from the drain port 15 and will not approach the cable, thereby avoiding the cable being affected by being soaked by rainwater.

[0023] Specifically, by Figure 1 and Figure 2 It can be seen that in this embodiment, one end surface of the bridge body 1 and the top plate 2 are provided with a mounting groove 8, and the other end surface corresponding to the mounting groove 8 is fixed with a mounting plate 12, and a screw hole 13 is provided on the mounting plate 12. The bridge body 1 is also provided with a positioning groove 7, and the positioning groove 7 is on the same side as the mounting groove 8. A positioning head 10 corresponding to the positioning groove 7 is fixed on the bridge body 1, and the positioning head 10 can be embedded in the positioning groove 7, and the mounting plate 12 can be embedded in the mounting groove 8. This setting can facilitate the connection and combination of multiple groups of cable bridges. The positioning head 10 and the mounting plate 12 are aligned and embedded in the positioning groove 7 and the mounting groove 8, and then the bolts are screwed into the screw holes 13 to fix them, which is convenient to use.

[0024] It should be noted that the parts not described in detail in this embodiment are all existing structural components in the relevant technical field, which are well known to technicians in the relevant fields, and the unique parts or slots in this embodiment can be purchased on the market or customized.

[0025] Working principle and use process of the utility model: When installing the outdoor cable bridge of the utility model, first use bolts to fix the top plate 2 through the installation feet 3, and then the bridge body 1 can be slid to install, and the wires are passed through the interlayer between the two partition plates 9. Since the bottom of the placement plate 6 is empty, the air volume will blow from the bottom of the placement plate 6 to the heat dissipation port 11, and will also blow from the main vent 4 to the auxiliary vent 14, so as to ventilate and dissipate heat. If rainwater enters from the main vent 4, it will slide down the water retaining plate 5 to the drain port 15, and then be discharged from the water outlet 17 at the bottom, so as to be waterproof and convenient to use.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
