Description

Technical Field

[0001] The utility model relates to the technical field of cable protection components, in particular to a power cable protection tube with strong pressure resistance. Background Art

[0002] At present, there are two common problems with cables in the process of power transmission. On the one hand, cables, especially power cables with relatively large capacity (such as power lines above 6 kilovolts), will objectively generate a large amount of heat during the power-on operation. Moreover, due to the constraints of cable structure, materials, external environment, etc., the generated heat is difficult to dissipate quickly, causing the cable to temperature rise rapidly. The temperature rise of the cable will not only lead to a decrease in the current carrying capacity of the cable, but also cause thermal breakdown of the cable in severe cases, accelerate the aging of the cable, and greatly affect the service life of the cable. On the other hand, the cable is squeezed externally during use, which can easily cause the wire core to break, thereby affecting signal and power transmission.

[0003] In order to prevent the cable from being damaged by external squeezing, a protective tube is usually installed outside the cable, and compression ribs are arranged inside the protective tube. The compression ribs are used to improve the strength of the protective tube, so that the cable is not easily damaged when the protective tube is squeezed. However, when the cable is squeezed, the force is usually applied from the upper part, that is, the upper half of the protective tube is easily damaged. The protective tubes in the prior art are all one-piece structures, which makes it impossible to partially replace the protective tube after it is damaged, increasing the cost of using the protective tube.

[0004] Therefore, there is a technical problem in the prior art that the power cable protection tube cannot be partially replaced. Summary of the invention

[0005] The utility model provides a power cable protection tube with strong pressure resistance, which solves the technical problem that the power cable protection tube cannot be partially replaced in the prior art.

[0006] Some implementation plans adopted to solve the above technical problems include:

[0007] A power cable protection tube with strong pressure resistance, comprising a tube body and a pressure-resistant component arranged outside the tube body;

[0008] The anti-pressure assembly includes a support seat and an anti-pressure seat arranged on the support seat, an installation space for installing the pipe body is formed between the anti-pressure seat and the support seat, the pipe body is installed on the support seat, and a buffer gap is arranged between the pipe body and the anti-pressure seat;

[0009] The anti-pressure seat is plugged into the support seat;

[0010] A compression-resistant beam is inserted in the compression-resistant seat.

[0011] Preferably, the compression seat comprises a transverse plate and a vertical plate arranged on the transverse plate, the vertical plates are arranged on both sides of the transverse plate, supporting ribs are arranged between the two vertical plates and the transverse plate, and connecting ribs are arranged between the two supporting ribs.

[0012] Preferably, the compression beam includes a side beam, and side mounting holes for mounting the side beam are formed between the support ribs and the transverse plate and the vertical plate.

[0013] Preferably, the side beam comprises a frame body and auxiliary ribs arranged in the frame body, and the frame body and the auxiliary ribs are an integrated structure.

[0014] Preferably, a middle mounting hole is formed between the connecting rib, the transverse plate and the two supporting ribs, and the compression beam further comprises a middle beam, which is inserted into the middle mounting hole.

[0015] Preferably, the middle beam is provided with a weight-reducing groove for reducing the weight of the middle beam, and the weight-reducing groove is arranged along the length direction of the middle beam.

[0016] Preferably, there are four weight-reducing grooves, and the four weight-reducing grooves form cross-shaped extrusion ribs in the middle beam, and the middle beam and the extrusion ribs are an integrated structure.

[0017] Preferably, the vertical plate is provided with an inserting plate, the inserting plate and the vertical plate are an integrated structure, and the support seat is provided with a slot that cooperates with the inserting plate.

[0018] Preferably, the tube body and the support seat are an integrated structure, the support seat includes a frame, a portion of the tube body is located in the frame, and a portion of the tube body protrudes from the frame and extends into the anti-compression seat.

[0019] Preferably, ribs for improving the strength of the support seat are arranged in the frame, the ribs and the frame are an integrated structure, and the tube body is not in contact with the ribs.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. By arranging a pressure-resistant component outside the tube body, and the pressure-resistant component includes a support seat and a pressure-resistant seat, the pressure-resistant seat is located above the support seat, and after the pressure-resistant seat is damaged by external extrusion force, the pressure-resistant seat can be replaced independently, and the support seat and the tube body do not need to be replaced together, so that the damaged part of the power cable protection tube can be partially replaced, reducing the use cost of the power cable protection tube.

[0022] 2. By setting up the compression beam, the compression beam is used to improve the strength of the compression seat, so that the compression seat can withstand a greater force, thereby optimizing the performance of the power cable protection tube.

[0023] 3. By setting the buffer gap, the anti-pressure seat does not contact the tube body. After the anti-pressure seat is deformed, it will not squeeze the tube body immediately, thereby preventing the anti-pressure seat from squeezing the tube body after slight deformation, further optimizing the performance of the power cable protection tube.

[0024] 4. The anti-pressure seat is plugged into the support seat. The anti-pressure seat and the support seat are easy to assemble or disassemble. When the anti-pressure seat needs to be replaced, the anti-pressure seat can be conveniently removed for replacement, thereby improving the maintenance efficiency of the power cable protection tube.

[0038] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0039] Reference Figures 1 to 6 As shown, a power cable protection tube with strong pressure resistance comprises a tube body 1 and a pressure-resistant component 2 arranged outside the tube body 1;

[0040] The anti-pressure assembly 2 includes a support seat 21 and an anti-pressure seat 22 disposed on the support seat 21, an installation space for installing the tube body 1 is formed between the anti-pressure seat 22 and the support seat 21, the tube body 1 is installed on the support seat 21, and a buffer gap 221 is provided between the tube body 1 and the anti-pressure seat 22;

[0041] The anti-pressure seat 22 is plugged into the support seat 21;

[0042] The anti-compression seat 22 is inserted with an anti-compression beam 3 .

[0043] The power cable protection tube with pressure resistance function is usually installed below the ground and is subjected to pressure from the ground during actual use. That is, one half of the power cable protection tube is subjected to the force, while the lower half usually does not need to withstand the extrusion force. Therefore, the upper half of the power cable protection tube is easily damaged, while the lower half is usually not easily damaged. After the upper half is damaged, the upper half can be directly replaced without replacing the entire power cable protection tube.

[0044] The anti-pressure component 2 includes a support seat 21 and an anti-pressure seat 22. The anti-pressure seat 22 is located above the support seat 21. The support seat 21 is used to support the anti-pressure seat 22 so that the anti-pressure seat 22 is in the correct position. At the same time, the support seat 21 is also used to position the tube body 1 so that the tube body 1 has a correct position relative to the anti-pressure component 2.

[0045] The anti-pressure seat 22 is plugged into the support seat 21. After the anti-pressure seat 22 is deformed by the force, the anti-pressure seat 22 can be easily replaced separately, thereby reducing the use cost of the power cable protection tube.

[0046] Since the anti-compression seat 22 usually needs to withstand a larger force, in order to improve the strength of the extrusion seat, an anti-compression beam 3 is arranged in the anti-compression seat 22 so that the anti-compression seat 22 can withstand a larger force.

[0047] Reference Figures 1 to 6 As shown, in some embodiments, the anti-compression seat 22 includes a horizontal plate 222 and a vertical plate 223 arranged on the horizontal plate 222, both sides of the horizontal plate 222 are provided with the vertical plates 223, support ribs 224 are arranged between the two vertical plates 223 and the horizontal plate 222, and connecting ribs 225 are arranged between the two support ribs 224.

[0048] The supporting ribs 224 are used to increase the strength between the vertical plate 223 and the horizontal plate 222, and the connecting ribs 225 are used to increase the bending strength of the horizontal plate 222. The horizontal plate 222 is deformed downward after being subjected to the extrusion force. At this time, the connecting ribs 225 tighten the two vertical plates 223 through the two supporting ribs 224, so that the horizontal plate 222 and the entire anti-compression seat 22 are not easily deformed, thereby improving the strength of the anti-compression seat 22.

[0049] In some embodiments, the compression beam 3 includes a side beam 31 , and a side mounting hole 226 for mounting the side beam 31 is formed between the support rib 224 and the transverse plate 222 and the vertical plate 223 .

[0050] The side beam 31 includes a frame body 311 and a secondary rib 312 disposed in the frame body 311 . The frame body 311 and the secondary rib 312 are an integrated structure.

[0051] The provision of the secondary ribs 312 further improves the strength of the side beam 31 , thereby improving the strength of the anti-compression seat 22 .

[0052] Reference Figures 1 to 6 As shown, in some embodiments, an intermediate mounting hole 227 is formed between the connecting rib 225 , the cross plate 222 , and the two supporting ribs 224 , and the compression beam 3 also includes an intermediate beam 32 , which is inserted into the intermediate mounting hole 227 .

[0053] The middle beam 32 is provided with a weight-reducing groove 321 for reducing the weight of the middle beam 32 , and the weight-reducing groove 321 is provided along the length direction of the middle beam 32 .

[0054] There are four weight-reducing grooves 321 , and the four weight-reducing grooves 321 form cross-shaped extrusion ribs 322 in the middle beam 32 . The middle beam 32 and the extrusion ribs 322 are an integrated structure.

[0055] When the extrusion seat is deformed, the cross beam often bears the extrusion force, that is, the two sides of the cross plate 222 are squeezed toward the middle of the cross plate 222, causing the cross plate 222 to deform. Usually, an intermediate beam 32 is provided, which can effectively improve the strength of the cross plate 222. The cross plate 222 is not easy to deform when subjected to the force, thereby further improving the strength of the compression seat 22.

[0056] The provision of the support ribs 224 and the connection ribs 225 can not only improve the strength of the anti-compression seat 22 , but also position the middle beam 32 and the side beam 31 , thereby simplifying the structure of the anti-compression seat 22 and reducing the manufacturing cost of the anti-compression seat 22 .

[0057] Reference Figures 1 to 6 As shown, in some embodiments, the vertical plate 223 is provided with an inserting plate 2231 , the inserting plate 2231 and the vertical plate 223 are an integrated structure, and the support seat 21 is provided with a slot that cooperates with the inserting plate 2231 .

[0058] In some embodiments, the tube body 1 and the support seat 21 are an integrated structure, the support seat 21 includes a frame 211, a portion of the tube body 1 is located in the frame 211, and a portion of the tube body 1 protrudes from the frame 211 and extends into the anti-pressure seat 22.

[0059] The frame 211 is provided with ribs 212 for increasing the strength of the support seat 21 . The ribs 212 and the frame 211 are an integrated structure, and the tube body 1 is not in contact with the ribs 212 .

[0060] The provision of the ribs 212 increases the strength of the support base 21 , and the support collar is less likely to deform during long-term use.

[0061] When the anti-compression seat 22 is subjected to the extrusion force, the transverse plate 222 is usually deformed, that is, the transverse plate 222 bends downward. However, the downward bending of the transverse plate 222 does not form a large bending angle at one time, but is slightly bent. When the transverse plate 222 is slightly bent downward, since a buffer gap 221 is provided between the tube body 1 and the anti-compression seat 22, the buffer gap 221 serves to compensate for the slight lateral bending. When the transverse plate 222 is slightly bent or the bending amplitude of the transverse plate 222 is less than the thickness of the buffer gap 221, the transverse plate 222 does not contact the tube body 1, and the tube body 1 will not be damaged by the transverse plate 222. In other words, the slight bending of the transverse plate 222 does not cause the transverse plate 222 to contact the tube body 1, thereby preventing the tube body 1 from being damaged.

[0062] The arrangement of the ribs 212 and the buffer gaps 221 allows more spaces to be provided around the tube body 1, which can accelerate air convection, so that the tube body 1 has better heat dissipation performance, thereby allowing the power cable to operate within a reasonable temperature range, thereby extending the service life of the power cable.

[0063] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.

[0064] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.

Obviously, these details still fall within the scope covered by the subject technical solution of the utility model without departing from the subject technical solution of the utility model.
