Description

Technical Field

[0001] This utility model relates to the field of power pipeline technology, specifically to a power cable conduit with a pipe opening protection structure. Background Technology

[0002] Cable protection pipes are mainly installed at intersections of communication cables and power lines to prevent short circuits caused by power line breaks, which could energize communication cables and steel wire ropes. This protects cables, switches, and circuit boards from burning out the entire device. They also provide some isolation against magnetic field interference from power lines. Power cable communication protection pipes are made of rigid polyvinyl chloride pipes of various specifications, primarily from PVC resin with added stabilizers. They are characterized by corrosion resistance, high temperature resistance, light weight, low project cost, and long service life. However, the pipe ends of existing power cable pipes are not protected during storage and transportation, making them susceptible to impact damage, which can lead to safety hazards and construction risks.

[0003] A search revealed a utility model patent with publication number CN211296047U, which specifically discloses a power cable conduit with a conduit opening protection function. The conduit includes a power cable conduit body and a conduit opening protector. The conduit opening protector is fitted onto the openings at both ends of the power cable conduit body. The conduit opening protector includes a plug-shaped protector body with outwardly extending peripheral sides forming a limiting part. The limiting part engages with the edge of the conduit opening of the power cable conduit body. Through the cooperation between the conduit opening protector and the power cable conduit body, the conduit opening is protected during transportation and storage, preventing damage due to impacts, thus effectively ensuring product and construction safety.

[0004] The aforementioned patent merely uses a pipe end protector fitted onto the pipe ends of the power cable conduit. The pipe end protector includes a plug-shaped protector body with a limiting part extending outward from the periphery of the protector body. The limiting part engages with the edge of the pipe end of the power cable conduit. Through the cooperation between the pipe end protector and the power cable conduit, the pipe end of the power cable conduit is protected during transportation and storage, preventing damage due to impacts. This effectively ensures product and construction safety. However, it cannot adequately protect the pipe end against pressure or shock, and it is not convenient for providing pressure and shock resistance protection. Furthermore, the adjustable nature of the protective structure is weak, making it unsuitable for use with various cable conduit specifications, resulting in low practicality.

[0005] Therefore, it is necessary to invent a power cable conduit with a pipe opening protection structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a power cable conduit with a pipe opening protection structure. Through a buffer structure composed of a first pressure-resistant airbag, a second pressure-resistant airbag, an air inlet, a ball plug, and an exhaust port, when the first outer pressure-resistant airbag is impacted, the gas inside the airbag pushes against the ball plug, causing it to detach from the air inlet and enter the second pressure-resistant airbag through the vent and air inlet, thus pressurizing the second pressure-resistant airbag to counteract the impact force. After the impact force disappears, the second pressure-resistant airbag returns to positive pressure, allowing the gas to slowly return to the first pressure-resistant airbag through the exhaust port, preparing for the next impact. This provides timely buffering. By increasing the contact area between the second and first pressure-resistant airbags, the support force of the second pressure-resistant airbag on the fixing frame is enhanced, significantly improving the overall pressure resistance of the fixing frame structure. This provides efficient pressure protection for the cable conduit, solving the problems of existing technologies that cannot adequately protect the pipe opening from pressure, are inconvenient for pressure and shock protection, have weak adjustability, are not applicable to various cable conduit specifications, and have low practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power cable conduit with a pipe opening protection structure, comprising a cable conduit body and a protector, wherein the protector is movably sleeved at the end of the cable conduit body, and the protector includes a fixing frame, wherein the number of fixing frames is set to two, the two fixing frames are symmetrically distributed about the central axis of the cable conduit body, and the ends of the two fixing frames are fixedly installed by fixing bolts; the outer walls of both fixing frames are each arranged in a ring array of pressure-resistant airbags, the pressure-resistant airbags being symmetrically distributed about the central axis of the cable conduit body. The inner walls of both fixed frames are arranged in a ring array of pressure-resistant airbags. The pressure-resistant airbags are symmetrically distributed about the central axis of the cable conduit. The fixed frames are fixedly connected to protective frames through the pressure-resistant airbags. A vent is connected between the pressure-resistant airbags and the pressure-resistant airbags. A partition is fixedly installed inside the vent. The partition has an air inlet and an air outlet. The air inlet is located in the middle of the partition. There are two air outlets, which are symmetrically distributed about the central axis of the partition. A ball plug is movably engaged inside the air inlet.

[0008] Preferably, a connecting plate is fixedly connected to the side of the ball plug, and two springs are provided on the connecting plate. The two springs are symmetrically distributed about the central axis of the connecting plate, and the springs are fixedly connected to the partition plate.

[0009] Preferably, the inner wall of the protective frame is hinged with an adjusting plate via a connecting seat. The number of adjusting plates is set to two, and the two adjusting plates are symmetrically distributed about the central axis of the protective frame. A spring connects the adjusting plate to the protective frame.

[0010] Preferably, the fixed frame has shock-absorbing silicone distributed in an annular array, and two adjacent shock-absorbing silicone materials are symmetrically distributed about the central axis of the pressure-resistant airbag.

[0011] Preferably, a support strip is fixedly provided inside the shock-absorbing silicone, and reinforcing ribs are evenly provided inside the support strip, with the reinforcing ribs being fixedly connected to the inner wall of the support strip.

[0012] Preferably, the side of the adjusting plate is fixedly connected with a wear-resistant baffle.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. The buffer structure, consisting of pressure-resistant airbag one, pressure-resistant airbag two, air inlet, ball plug, and exhaust port, enables the gas inside the outer pressure-resistant airbag one to push against the ball plug when impacted, causing it to detach from the air inlet and enter the pressure-resistant airbag two through the vent and air inlet, thus pressurizing the pressure-resistant airbag two to counteract the impact force. After the impact force disappears, the pressure-resistant airbag two returns to positive pressure, allowing the gas to slowly return to the pressure-resistant airbag one through the exhaust port in preparation for the next impact, thus playing a timely buffering role. By increasing the contact area between the pressure-resistant airbag two and the pressure-resistant airbag one, the support force of the pressure-resistant airbag two on the fixed frame is enhanced, significantly improving the overall pressure resistance of the fixed frame structure and effectively protecting the cable conduit from pressure.

[0015] 2. The distance between the two fixing frames can be adjusted by fixing bolts. The adjusting plate inside the fixing frame, which is used to contact the surface of the pipe opening, is kept in close contact with it by the expansion and rotation of spring 1. It can be used for cable pipes of different specifications, improving the practicality of the structure. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6The power cable conduit shown includes a cable conduit body 1 and a protector 2. The protector 2 is movably sleeved at the end of the cable conduit body 1. The protector 2 includes two fixing frames 3, symmetrically distributed about the central axis of the cable conduit body 1. The ends of the two fixing frames 3 are fixedly installed by fixing bolts 4. Pressure-resistant airbags 5 are arranged in a ring array on the outer walls of both fixing frames 3, symmetrically distributed about the central axis of the cable conduit body 1. Pressure-resistant airbags 6 are arranged in a ring array on the inner walls of both fixing frames 3, symmetrically distributed about the central axis of the cable conduit body 1. A protective frame 7 is fixedly connected to the fixing frames 3 through the pressure-resistant airbags 6. A vent 11 connects the pressure-resistant airbags 5 and 6, and a fixed part is provided inside the vent 11. The partition 12 has an air inlet 13 and an exhaust 17. The air inlet 13 is located in the middle of the partition 12, and there are two exhaust 17s. The two exhaust 17s are symmetrically distributed about the central axis of the partition 12. A ball plug 14 is movably engaged inside the air inlet 13. Two fixed frames 3 are connected by fixed bolts 4 and installed at the opening of the cable pipe 1. The first pressure-resistant airbag 5 is set on the outside, and the second pressure-resistant airbag 6 is set between the fixed frame 3 and the protective frame 7. The inner cavities of the first pressure-resistant airbag 5 and the second pressure-resistant airbag 6 are connected through the vent hole 11. The ball plug 14 can block the air inlet 13. The second spring 16 realizes the elastic engagement between the ball plug 14 and the air inlet 13, which is convenient for resetting and re-blocking the air inlet 13. The inner cavity structure of the exhaust 17 is set as conical, and the gas discharge speed is greater than the discharge speed.

[0027] A connecting plate 15 is fixedly connected to the side of the ball plug 14. Two springs 16 are provided on the connecting plate 15, and the two springs 16 are symmetrically distributed about the central axis of the connecting plate 15. The springs 16 are fixedly connected to the partition plate 12.

[0028] The inner wall of the protective frame 7 is hinged with an adjusting plate 9 via a connecting seat 8. There are two adjusting plates 9, which are symmetrically distributed about the central axis of the protective frame 7. A spring 10 connects the adjusting plate 9 to the protective frame 7. Due to the rotational connection of the connecting seat 8 and the elastic expansion of the spring 10, the two adjusting plates 9 are kept in close contact with the outer wall of the cable conduit 1, so that the structure can be used for pipe openings of different specifications.

[0029] The fixed frame 3 has shock-absorbing silicone 18 arranged in a ring array inside. Two adjacent shock-absorbing silicone 18 are symmetrically distributed about the central axis of the pressure-resistant airbag 5. The support bar 19 and the fixed frame 3 are provided with shock-absorbing silicone 18, which plays a good role in pressure resistance and shock absorption, improves the structural stability of the fixed frame 3, and better protects the pipe opening.

[0030] The shock-absorbing silicone 18 has a support strip 19 fixedly installed inside. The support strip 19 has reinforcing ribs 20 evenly arranged inside. The reinforcing ribs 20 are fixedly connected to the inner wall of the support strip 19. The setting of the reinforcing ribs 20 can ensure the maximum support capacity of the pipe body.

[0031] The side of the adjusting plate 9 is fixedly connected with an anti-wear strip 21. The anti-wear strip 21 can wrap around the side of the pipe opening with the adjusting plate 9, and play a good anti-wear role.

[0032] The working principle of this practical application is as follows:

[0033] Two fixing frames 3 are respectively attached tightly to the bottom and bottom of the cable conduit 1 and fixedly connected by fixing bolts 4. Two adjusting plates 9 and anti-wear baffles 21 are attached tightly to the outer wall and sides of the cable conduit 1 for effective protection, reducing contact with external objects and collisions. The buffer structure composed of pressure-resistant airbag 1 5, pressure-resistant airbag 2 6, air inlet 13, ball plug 14 and exhaust port 17 ensures that when the outer pressure-resistant airbag 1 5 is impacted, the gas inside the airbag pushes against the ball plug 14, causing it to detach from the air inlet 13 and pass through the vent 11 and into the air outlet. Air vent 13 enters the second pressure-resistant airbag 6, pressurizing it to counteract the impact. After the impact disappears, the second pressure-resistant airbag 6 returns to positive pressure, allowing gas to slowly return to the first pressure-resistant airbag 5 through the exhaust vent 17, preparing for the next impact. This provides timely buffering. By increasing the contact area between the second pressure-resistant airbag 6 and the first pressure-resistant airbag 5, the support force of the second pressure-resistant airbag 6 on the fixed frame 3 is enhanced, greatly improving the overall pressure resistance of the fixed frame 3 and the protection of the cable conduit 1's opening.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
