Description

Technical Field

[0001] This utility model relates to the field of pipe technology, specifically to a PE power pipe that is resistant to external extrusion. Background Technology

[0002] PE power conduit is a type of pipe made from high-density polyethylene (HDPE) and is widely used for the protection of power cables. This type of pipe has excellent physical and mechanical properties, such as corrosion resistance, aging resistance, impact resistance, high mechanical strength, good electrical insulation properties, and a long service life.

[0003] However, the current PE power pipes still need to be improved in terms of their ability to withstand external extrusion. Moreover, PE power pipes are usually connected using traditional electrofusion or hot fusion methods, which is time-consuming, labor-intensive, and inconvenient.

[0004] The utility model discloses a multi-porous PE power pipe that is resistant to torsion and deformation and is waterproof. It includes a pipe body with an outer functional layer inside, an elastic rubber body on the inner wall of the outer functional layer, five inner tubes inside the elastic rubber body, an inner functional layer on each inner tube, an outer waterproof membrane inside the outer functional layer, and an outer waterproof layer on the inner wall of the outer waterproof membrane. This multi-porous PE power pipe, with its outer waterproof membrane and outer waterproof layer preventing water vapor from eroding the pipe body, and its inner waterproof layer and inner waterproof membrane preventing water vapor from eroding the inner tubes, and its drying layer absorbing water vapor that penetrates the inner tubes, achieves good waterproofing. The use of elastic rubber body, buffer layer, elastic buffer ball, and buffer springs to buffer external forces, and connecting body, arc-shaped buffer body, and spaced springs to prevent the inner tubes from being squeezed together by external forces, greatly improves the compressive strength and prevents the power pipe from being torsion and deformed by external forces.

[0005] While the aforementioned patent achieves good waterproofing by using an external waterproof membrane with the waterproof properties of PTFE material to initially prevent water vapor from corroding the pipe body, using an external waterproof layer with the waterproof properties of modified asphalt material to further prevent water vapor from corroding the pipe body, using an internal waterproof layer and an internal waterproof membrane with the waterproof properties of modified asphalt material and PTFE material to prevent water vapor from corroding the inner pipe, and using a drying layer with the water-absorbing properties of silica gel to absorb water vapor that has seeped into the inner pipe, the device lacks a connection mechanism, making it not quick and convenient to connect PE power pipes.

[0006] Therefore, it is necessary to invent a PE power pipe that is resistant to external compression to solve the above problems. Utility Model Content

[0007] The technical problem to be solved by this utility model is as follows: to provide a PE power pipe with high practicality and simple structure that can be operated easily and is resistant to external extrusion. This solves the problem mentioned in the background art that the current PE power pipe still needs to improve its ability to withstand external extrusion, and that the PE power pipe is usually connected by traditional electrofusion or hot fusion, which is time-consuming, labor-intensive and inconvenient.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A PE power pipe resistant to external compression includes a PE power pipe A. Multiple sets of pressure-resistant components are fixedly connected to the surface of the PE power pipe A. Each set of pressure-resistant components includes a steel wire mesh layer and a reinforcing ring. A connecting mechanism is inserted into one end of the PE power pipe A. The connecting mechanism includes a pipe cap A, a limiting ring A, a pipe clamp sleeve A, a rubber gasket A, and a double-threaded pipe. A pipe cap B is threaded to one end of the double-threaded pipe. A rubber gasket B is inserted into the inner wall of the double-threaded pipe, and the PE power pipe B is inserted into the inner wall of the rubber gasket B.

[0010] As a further embodiment of this utility model: multiple sets of the steel wire mesh layers are fixedly connected to the surface of the PE power pipe A, and reinforcing rings are fixedly connected to the surface of the multiple sets of steel wire mesh layers. By setting the reinforcing rings, the strength of the PE power pipe against external extrusion is improved.

[0011] As a further embodiment of this utility model: the pipe cap A is inserted into the surface of the PE power pipe A, a limiting ring A is inserted inside the pipe cap A, a pipe clamp sleeve A is attached to one end of the limiting ring A, a rubber pad A is attached to one end of the pipe clamp sleeve A, and a double-threaded pipe is inserted into the surface of the rubber pad A. The inner walls of the limiting ring A, the pipe clamp sleeve A, and the rubber pad A are all inserted into one end of the surface of the PE power pipe A. The double-threaded pipe serves to connect the pipe cap A and the pipe cap B.

[0012] As a further embodiment of this utility model: one end of the rubber pad B is connected to the pipe clamp sleeve B, and one end of the pipe clamp sleeve B is connected to the limiting ring B. The inner walls of the limiting ring B, the pipe clamp sleeve B, and the rubber pad B are all inserted into one end of the surface of the PE power pipe B. The setting of the limiting ring B and the pipe clamp sleeve B plays the role of limiting the position of the pipe cap B.

[0013] As a further embodiment of this utility model: both PE power pipe A and PE power pipe B are fixedly connected to a reinforcing layer inside, and glass fiber is added inside the two sets of reinforcing layers. The reinforcement layer improves the strength of the PE power pipe.

[0014] As a further embodiment of this utility model: a steel pipe layer is fixedly connected to the inner wall of the reinforcing layer, and a rubber layer is fixedly connected to the inner wall of the steel pipe layer. The steel pipe layer serves to enhance the strength of the PE power pipe.

[0015] As a further embodiment of this utility model: the rubber layer is fixedly connected with a separator tube, and there are five sets of separator tubes. The separator tubes serve to separate the wires laid inside the PE power pipe.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up a reinforcing layer and pressure-resistant components, when using this device, the reinforcing layer inside the PE power pipe A is firstly reinforced with glass fiber, which effectively enhances the strength of the PE power pipe A. At the same time, the steel wire mesh layer improves the strength of the reinforcing ring. The distribution of the reinforcing ring gives the surface of the PE power pipe A a corrugated shape, which can increase the rigidity of the pipe and help to disperse external pressure, thereby increasing the pipe's resistance to external extrusion.

[0018] 2. By using the pipe cap B and the connecting mechanism, when connecting two pipe sections, first insert the pipe cap A into one end of the PE power pipe A. At the same time, put the limiting ring A, pipe clamp sleeve A, and rubber gasket A onto one end of the PE power pipe A, allowing the pipe cap A to slide a certain distance on the surface of the limiting ring A. The limiting ring A also prevents the pipe cap A from falling off. Insert the double-threaded pipe onto the rubber gasket A. Similarly, install the pipe cap B, limiting ring B, pipe clamp sleeve B, and rubber gasket B onto one end of the PE power pipe B. Rotate the pipe cap A and pipe cap B, and the PE power pipe A and PE power pipe B can be connected through the double-threaded pipe. This is convenient, quick, and saves time and effort.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, a PE power pipe resistant to external extrusion includes a PE power pipe A1. Multiple sets of pressure-resistant components 2 are fixedly connected to the surface of the PE power pipe A1. The rigidity of the pipe can be increased by the setting of the reinforcing layer 9 and the pressure-resistant components 2, which is conducive to dispersing external pressure and increasing the pipe's resistance to external extrusion. The multiple sets of pressure-resistant components 2 include a wire mesh layer 201 and a reinforcing ring 202. One end of the PE power pipe A1 is connected to a connecting mechanism 3. The connecting mechanism 3 includes a pipe cap A301, a limiting ring A302, a pipe clamp sleeve A303, a rubber gasket A304, and a double-threaded pipe 305. One end of the double-threaded pipe 305 is threadedly connected to a pipe cap B4. Through the setting of the pipe cap B4 and the connecting mechanism 3, the PE power pipe A1 and the PE power pipe B6 can be connected through the double-threaded pipe 305, which is convenient, quick, time-saving and labor-saving. A rubber gasket B5 is inserted into the inner wall of the double-threaded pipe 305, and the PE power pipe B6 is inserted into the inner wall of the rubber gasket B5.

[0027] like Figure 2 As shown, multiple sets of steel wire mesh layers 201 are fixedly connected to the surface of PE power pipe A1, and reinforcing rings 202 are fixedly connected to the surface of the multiple sets of steel wire mesh layers 201. By setting the reinforcing rings 202, the strength of PE power pipe against external extrusion is improved.

[0028] like Figure 3As shown, the pipe cap A301 is inserted into the surface of the PE power pipe A1. A limiting ring A302 is inserted inside the pipe cap A301. One end of the limiting ring A302 is connected to a pipe clamp sleeve A303. One end of the pipe clamp sleeve A303 is connected to a rubber gasket A304. A double-threaded pipe 305 is inserted into the surface of the rubber gasket A304. The inner walls of the limiting ring A302, the pipe clamp sleeve A303, and the rubber gasket A304 are all inserted into one end of the surface of the PE power pipe A1. The double-threaded pipe 305 serves to connect the pipe cap A301 and the pipe cap B4.

[0029] like Figure 3 As shown, one end of the rubber pad B5 is connected to the pipe clamp sleeve B7, and one end of the pipe clamp sleeve B7 is connected to the limit ring B8. The limit ring B8, the pipe clamp sleeve B7 and the inner wall of the rubber pad B5 are all inserted into one end of the surface of the PE power pipe B6. The limit ring B8 and the pipe clamp sleeve B7 are used to limit the pipe cap B4.

[0030] like Figure 4 As shown, both PE power pipe A1 and PE power pipe B6 have a reinforcing layer 9 fixedly connected inside. Glass fiber is added inside the two sets of reinforcing layers 9. The setting of the reinforcing layer 9 plays the role of improving the strength of the PE power pipe.

[0031] like Figure 4 As shown, a steel pipe layer 10 is fixedly connected to the inner wall of the reinforcing layer 9, and a rubber layer 11 is fixedly connected to the inner wall of the steel pipe layer 10. The steel pipe layer 10 serves to enhance the strength of the PE power pipe.

[0032] like Figure 4 As shown, five sets of partition tubes 12 are fixedly connected inside the rubber layer 11. The partition tubes 12 serve to separate the wires laid inside the PE power pipe.

[0033] The working principle of this utility model is as follows: When using this device, firstly, the reinforcing layer 9 inside the PE power pipe A1 is filled with glass fiber, which effectively enhances the strength of the PE power pipe A1. At the same time, the steel wire mesh layer 201 improves the strength of the reinforcing ring 202. The distribution of the reinforcing ring 202 makes the surface of the PE power pipe A1 corrugated.

[0034] Secondly, when connecting the two pipe sections, first insert the pipe cap A301 into one end of the PE power pipe A1, and at the same time, put the limiting ring A302, pipe clamp sleeve A303, and rubber gasket A304 onto one end of the PE power pipe A1, so that the pipe cap A301 can slide a certain distance on the surface of the limiting ring A302. The limiting ring A302 can also prevent the pipe cap A301 from falling off. Insert the double-threaded pipe 305 onto the rubber gasket A304. Similarly, install the pipe cap B4, limiting ring B8, pipe clamp sleeve B7, and rubber gasket B5 onto one end of the PE power pipe B6, and rotate the pipe cap A301 and pipe cap B4.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
