Description

Technical Field

[0001] This utility model relates to the field of cable installation equipment technology, and in particular to a cable bracket. Background Technology

[0002] A cable support is a device used to support cables. During the laying and use of cables, cable supports play a vital role. They can fix the cables, prevent them from sagging due to their own weight, and ensure that the cables are laid according to the designed path. For example, in the cable trenches of large factories or buildings, many cables are neatly arranged by cable supports, so that they will not be tangled or piled up due to their weight.

[0003] The existing cable supports are relatively conventional; for example, high-voltage cables will generate heat during operation on the cable supports, and prolonged heating can lead to cable damage / burning. In order to reduce the occurrence of cable faults or cable damage, corresponding measures need to be taken on the basis of the existing ones. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a cable bracket.

[0008] The bracket has a third through hole that mates with the first through hole. The bracket is connected to the column by a bolt assembly that passes through the first through hole and the third through hole. The top surface of the bracket has multiple heat dissipation holes and grooves for filling heat dissipation fluid along the extension direction.

[0009] Preferably, the heat dissipation agent is a phase change energy storage material layer, which is filled into the groove by injection molding, and its thickness is 0.8-0.9 times the depth of the groove.

[0013] Base layer: Zinc-aluminum based anti-corrosion layer with a thickness of 50-80μm;

[0014] Intermediate layer: a ceramicized fireproof layer with a thickness of 100-150μm;

[0015] Surface layer: 20-30μm thick hydrophobic layer of fluoropolymer.

[0016] Preferably, the ceramicized fireproof layer is composed of silicate base material and ceramic fiber in a mass ratio of 3:1, and the fluoropolymer hydrophobic layer is a polytetrafluoroethylene dispersion coating.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 As shown, this embodiment provides a cable bracket, including:

[0027] The column 1 has a plurality of first through holes 12 arranged at equal intervals along its extension direction, and second through holes 13 located at the position of the reinforcing rib 11 of the column 1.

[0028] The bracket 2 has a third through hole 22 that mates with the first through hole 12. The bracket 2 is connected to the column 1 by a bolt assembly 3 that passes through the first through hole 12 and the third through hole 22. The top surface of the bracket 2 has a plurality of heat dissipation holes 23 and a groove 24 for filling heat dissipation agent along the extension direction.

[0029] Overall, the bracket 2 is connected to the column 1 by bolt assembly 3 through the first through hole 12 and the third through hole 22, and the column 1 is fixed by fixing assembly through the second through hole 13. When the cable is placed on the top surface of the bracket 2, the top surface heat dissipation hole 23 and groove 24 are designed to improve the overall thermal management capability of the bracket 2 through dual-path coordinated heat dissipation, avoid damage / burning of the cable due to prolonged heat generation, reduce the occurrence of cable failures, and improve the safety of cable use.

[0030] The height of the bracket 2 is adjustable by using the first through holes 12 that are set at equal intervals to adapt to different cable layout requirements.

[0031] like Figures 3-4 As shown, in this embodiment, the heat dissipation agent is a phase change energy storage material layer, which is filled into the groove 24 by injection molding, and its thickness is 0.8-0.9 times the depth of the groove 24.

[0032] Specifically, the heat dissipation agent is a phase change energy storage material layer, and the thickness retains 10%-20% expansion space, which can avoid the deformation of the support structure caused by the thermal expansion of the material; and the injection molding process can ensure the bonding strength between the material and the substrate interface, forming a continuous heat conduction network.

[0033] like Figures 1-3 As shown, in this embodiment, the side of the bracket 2 is provided with symmetrically distributed weight-reducing grooves 21, and the bottom of the heat dissipation hole 23 passes through the weight-reducing grooves 21.

[0034] By using symmetrically arranged weight-reducing grooves 21, the bracket 2 is made lighter while ensuring its bending stiffness, thus improving the stability of the bracket 2 installation. Furthermore, by having the bottom of the heat dissipation hole 23 pass through the weight-reducing groove 21, an air convection channel can be formed, improving air circulation efficiency and thereby enhancing the heat dissipation effect of the cable.

[0035] like Figures 1-2 As shown, in this embodiment, the cable bracket is made of one of the following materials: galvanized flat steel, fiberglass, or concrete.

[0036] By providing multiple material options for bracket 2, users can select the appropriate material for bracket 2 based on its actual use and usage requirements, without any restrictions.

[0037] like Figures 1-2 As shown, in this embodiment, when fiberglass is selected, its surface is coated with a functional coating, which includes:

[0038] Base layer: Zinc-aluminum based anti-corrosion layer with a thickness of 50-80μm;

[0039] Intermediate layer: a ceramicized fireproof layer with a thickness of 100-150μm;

[0040] Surface layer: 20-30μm thick hydrophobic layer of fluoropolymer.

[0041] Specifically, the zinc-aluminum based anti-corrosion layer is formed into a dense anti-corrosion layer through thermal spraying, which can improve the anti-corrosion performance of the bracket 2 and thus extend its service life; the fireproof layer can effectively prevent the spread of fire and protect the cable in the event of a fire, preventing the cable from falling; the hydrophobic layer can effectively improve the hydrophobicity of the surface of the bracket 2, thereby preventing the cable from being damaged by moisture, extending the cable's service life, and also preventing the surface of the bracket 2 from rusting.

[0042] like Figures 1-3 As shown, in this embodiment, the ceramicized fireproof layer is composed of silicate base material and ceramic fiber in a mass ratio of 3:1, and the fluoropolymer hydrophobic layer is a polytetrafluoroethylene dispersion coating.

[0043] Specifically, the ceramicized fireproof layer is made of potassium silicate, a silicate-based material, and ceramic fiber mixed in a 3:1 ratio. When the support 2 is exposed to high temperatures, the ceramicized fireproof layer forms a porous fire-resistant structure after sintering, which can effectively improve the overall fire resistance of the support 2.

[0044] like Figures 1-3 As shown, in this embodiment, the heat dissipation holes 23 are cylindrical and arranged at equal intervals along the top surface of the support 2. A downwardly recessed guide groove 231 is provided between adjacent heat dissipation holes 23, and the inner wall of the weight reduction groove 21 has a gradually expanding frustum structure.

[0045] By setting a guide groove 231 between adjacent heat dissipation holes 23, the drainage speed of the bracket 2 can be improved, preventing water accumulation and avoiding water corrosion of the cable. By making the inner wall of the weight reduction groove 21 a gradually expanding frustum structure, excessive stress concentration can be avoided, the stress distribution can be uniform, and the overall stability of the bracket 2 can be improved.

[0046] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
