Description

Technical Field

[0001] The utility model belongs to the field of electric power pipeline equipment, and in particular relates to a pipeline with a built-in pressure-bearing structure. Background Art

[0002] The power pipeline is a pipeline system used to lay and protect power cables. Although the current power pipeline itself has a certain pressure resistance, adding a pressure-bearing structure can further enhance the pressure-bearing capacity of the pipeline to cope with higher pressure situations that may occur and ensure the safe operation of the power system. In actual use, the current power pipeline has the problem of no built-in pressure-bearing structure. Once faced with greater pressure, the pipeline is prone to deformation or even rupture, which will not only affect the normal transmission of electricity, but may also cause safety accidents and threaten people's lives and property. This is because of the lack of a pressure-bearing structure. The lack of a pressure-bearing structure will not only lead to the above problems, but there may also be power pipelines without a built-in pressure-bearing structure, whose pressure resistance is limited. In some special environments or emergencies, such as geological disasters, construction damage, etc., the pipeline may not be able to withstand external pressure and be damaged, resulting in power supply interruption, which brings inconvenience and losses to production and life. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a pipeline with a built-in pressure-bearing structure, comprising: an external pressure-bearing component 100, a pipeline body 200 and an internal pressure-bearing component 240, the external pressure-bearing component 100 comprises: an outer shell 110, a rubber pad 110, a fixing rod 130 and an arc plate 131, the outer surface of the outer shell 110 is installed with a rubber pad 110, the inner part of the outer shell 110 is installed with a fixing rod 130, and the end of the fixing rod 130 away from the outer shell 110 is installed with an arc plate 131 ... A pipe body 200 is installed inside the pressure-bearing component 100, and the pipe body 200 includes: an external layer 210, a buffer layer 220 and a tensile layer 230. An internal pressure-bearing component 240 is installed inside the tensile layer 230. The internal pressure-bearing component 240 includes: a column 241, a movable column 243, a buffer 242 and an arc plate 244. The movable column 243 is movably installed inside the column 241, and the arc plate 244 is installed on the upper end of the movable column 243. The buffer 242 is installed inside the column 241.

[0021] See also Figures 1 to 4 As the first embodiment of the utility model: the shell 110 is in a U-shaped structure, the corners of the shell 110 are designed with arc chamfers, and a fixing rod 130 is installed at each of the four corners inside the shell 110. The fixing rod 130 is vertical relative to the pipe body 200, and the curvature of the side surface of the arc plate 131 away from the fixing rod 130 matches the curvature of the outer surface of the pipe body 200.

[0022] The pipe body 200 is composed of an outer layer 210, a buffer layer 220 and a tensile layer 230 from outside to inside. A plurality of twisted compression cables 211 are evenly installed inside the outer layer 210. The buffer layer 220 is made of natural rubber, and the tensile layer 230 is made of compression fiber. The thickness of the outer layer 210, the buffer layer 220 and the tensile layer 230 are the same.

[0023] During use, when the pipe body 200 is subjected to external pressure, the outer shell 110 on the outer surface of the pipe body 200 and the rubber pad 110 on the surface of the outer shell 110 can protect the pipe body 200, firstly transmit the external pressure to the outer shell 110, and then the outer shell 110 transmits the pressure to the fixing rod 130, and then the fixing rod 130 transmits the pressure to the arc plate 131, and then transmits it to the pipe body 200. At this time, the outer shell 110, together with the fixing rod 130 and the arc plate 131, can share and withstand more external pressure, thereby improving the overall pressure-bearing performance of the pipe. At the same time, the fixing rod 130 and the arc plate 131 can firmly fix the pipe body 200 in the outer shell 110 to prevent the pipe from shaking or shifting during the pressure-bearing process.

[0024] See also Figures 1 to 4 As the second embodiment of the utility model: the inner surface of the tensile layer 230 is evenly and annularly mounted with a plurality of built-in pressure-bearing components 240, and the end of the built-in pressure-bearing component 240 away from the tensile layer 230 is mounted with an electric inner core through an arc plate 244;

[0025] The inner surface of the tensile layer 230 is evenly mounted with a plurality of cylinders 241 in an annular shape, and a buffer 242 is mounted inside the cylinder 241. The buffer 242 is a spring buffer, and one end of the buffer 242 away from the cylinder 241 is connected to the lower end of the movable column 243;

[0026] The end of the movable column 243 away from the buffer 242 is installed with a second arc plate 244, and the side surface of the second arc plate 244 away from the movable column 243 abuts against the outer surface of the power inner core, and the curvature of the side surface of the second arc plate 244 away from the movable column 243 matches the outer surface of the power inner core;

[0027] During use, when the pressure is transmitted to the pipe body 200, the outer layer 210, the buffer layer 220 and the tensile layer 230 inside the pipe body 200 can absorb part of the pressure. The pressure-resistant cable 211 inside the outer layer 210, the rubber material inside the buffer layer 220 and the pressure-resistant fiber inside the tensile layer 230 can all absorb the pressure, thereby protecting the safety of the power core inside the pipe body 200. When the pressure is transmitted to the innermost part of the pipe body 200, the pressure will be transmitted to the column 241, the movable column 243 and the arc plate 244. At this time, The buffer 242 inside the column 241 (the buffer 242 is a spring buffer, which is a prior art and whose working principle and specific structure are not described in detail here) will absorb the pressure, thereby achieving the purpose of bearing pressure inside the pipeline body 200. The buffer 242 between the column 241 and the movable column 243 can evenly disperse the external pressure to each built-in pressure-bearing component 240, which improves the pressure-bearing effect, thereby reducing the impact of pressure fluctuations on the electric core and protecting the safety of the inner core. In combination with the external pressure-bearing component 100, the pipeline body 200 can achieve a good pressure-bearing effect by bearing pressure inside and outside at the same time.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
