Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a cable protection hose at a device connection. Background Art

[0002] Cable protection conduits are mechanically strong metal tubes installed over cables to protect them from damage. Currently, the most common cable protection conduits on the market are PP corrugated tubes and metal hoses, all of which are fully enclosed. Outdoor electrical equipment operates in relatively harsh environments. For example, during prolonged rainy weather, simply plugging the conduit openings is ineffective at providing adequate protection. Prolonged accumulation of water can cause water to accumulate within the conduit, potentially leaking into the equipment through the conduit terminals and causing damage.

[0003] Therefore, it is of great practical significance to develop a cable protection tube that can solve the problem of water accumulation in the tube. Utility Model Content

[0004] Due to the above-mentioned defects in the prior art, the utility model provides a cable protection tube that can solve the problem of water accumulation in the tube. By modifying the protection tube, the design is changed from a fully sealed form to a microporous structure. The microporous design can essentially solve the problem of water accumulation in the tube. On the other hand, it can also reduce the loss of sealing materials in the on-site pipe mouth part, reduce the cost of use, and overcome the defect of the existing cable protection tube that is prone to water accumulation.

[0005] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0006] A cable protection hose for equipment connection, which is a tubular structure and includes a plurality of corrugated sections and a plurality of corrugated microporous connecting sections that are sequentially arranged and connected to each other;

[0007] Micropores are formed on the wall surface of the corrugated microporous connection section;

[0008] A cylindrical stress reinforcement net is arranged in the protective hose, and the stress reinforcement net is fixedly connected to the inner walls of the corrugated section and the corrugated microporous connecting section.

[0009] The cable protection hose at the equipment connection of the utility model has a reasonable structural design and adopts a design form of a corrugated section and a corrugated microporous connection section interval. The corrugated section can give the hose flexibility and the ability to freely expand and contract. The micropores on the corrugated microporous connection section can provide the hose with a water-conducting function to avoid water accumulation in the pipe. In order to avoid the influence of the micropores on the overall structural strength, a fixed cylindrical stress reinforcement net is laid in the pipe to play the role of a reinforcing rib, which is used to reduce the force borne by the external structure and the load of the corrugated section to extend the service life. It has good application prospects.

[0010] As the preferred technical solution:

[0011] In the cable protective hose at the equipment connection as described above, the corrugated microporous connection section is a cylindrical structure.

[0012] In the cable protective hose at the equipment connection as described above, the micropores are evenly distributed around the wall surface of the corrugated micropore connection section.

[0013] In the cable protection hose at the equipment connection as described above, the stress reinforcement net is bonded to the inner wall of the cable protection hose at the equipment connection by integral quick dissolution.

[0014] In the cable protection hose at the equipment connection as described above, the stress reinforcement net is a nylon net, which serves as the inner skeleton of the hose.

[0015] In the cable protective hose at the equipment connection as described above, the corrugated section is a polypropylene corrugated section, which mainly has a buffering and protective effect on the cable and has significant effects in chemical corrosion resistance, heat resistance and electrical insulation.

[0016] As described above, in the cable protective hose at the equipment connection, the corrugated microporous connection section is a nylon corrugated microporous connection section, a polyphenylene sulfide corrugated microporous connection section or a polyethersulfone corrugated microporous connection section, which has high mechanical strength and good high temperature resistance.

[0017] The cable protection hoses at the connection points of the above-mentioned equipment and the equipment connection points can be fixed with various types of pipe joints and box joints commonly found in the market, which are widely used.

[0018] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0019] The above utility model has the following advantages or beneficial effects:

[0020] (1) The cable protection hose at the equipment connection of the utility model has a reasonable structural design and adopts a design form in which a corrugated section and a corrugated microporous connection section are spaced apart. The corrugated section can give the hose flexibility and the ability to freely expand and contract. The micropores on the corrugated microporous connection section can provide the hose with a water-conducting function to avoid water accumulation in the hose.

[0021] (2) In order to avoid the influence of micropores on the overall structural strength of the cable protection hose at the equipment connection of the utility model, a fixed cylindrical stress reinforcement net is laid inside the tube to play the role of reinforcement ribs, which is used to reduce the stress borne by the external structure and reduce the load of the corrugated joint to extend the service life. It has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
