Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable protection pipes, in particular to an enhanced high-strength cable protection pipe. BACKGROUND

[0002] In today's society, electricity and communication are the core components of infrastructure, and their stability and reliability are directly related to economic development, social stability and people's daily life. As the key carrier of power transmission and signal transmission, cables have been widely used in various infrastructure construction. However, cables face many external challenges during operation, which requires excellent cable protection pipes to provide reliable protection.

[0003] In the prior art, most cable protection pipes are prone to softening and deformation in high-temperature environments, such as summer high-temperature periods, high-load cable operation generating a large amount of heat, or in special scenarios close to heat sources, which not only destroys the wrapping and supporting effect of the protection pipe on the cable, but also may expose the cable directly to a high-temperature environment, accelerate the aging of the cable insulation layer, shorten the service life of the cable, and even cause cable failure, affecting the normal transmission of electricity or communication; at the same time, most traditional protection pipes use insulation materials that are easily affected by factors such as moisture and chemical substances during long-term use; in addition, traditional connection methods such as threaded connection are prone to thread slipping after repeated disassembly and assembly, resulting in loose connection and gaps between protection pipes, which cannot effectively protect the cable, while flange connection requires the use of a large number of bolts and gaskets, the installation process is complex, time-consuming and labor-intensive, and is prone to problems such as poor sealing, allowing external moisture, dust, etc. to enter the inside of the protection pipe, affecting the normal operation of the cable; in addition, during cable laying, the protection pipe needs to be fixed and supported to ensure its stable position; however, the traditional fixing method of the protection pipe is simple, such as using a rope to tie or a simple support to fix, which cannot provide sufficient fixing force and supporting force, and when subjected to external forces such as earthquakes, vehicle collisions, or long-term vibrations, the protection pipe is prone to displacement or deformation, thereby affecting the protection effect of the cable and increasing the risk of cable damage; finally, the traditional cable protection pipe lacks effective cable clamping devices inside, and the cable inside the protection pipe is prone to shaking, which will cause the cable to frequently rub against the inner wall of the protection pipe, resulting in wear and tear of the cable sheath, reducing the insulation performance and mechanical strength of the cable, and at the same time, the shaking cable may also affect the stability of power transmission, causing voltage fluctuations, signal interference, etc. Therefore, we propose an enhanced high-strength cable protection pipe. SUMMARY

[0004] The purpose of the present application is to provide an enhanced high-strength cable protection pipe to solve the problems raised in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A protective tube body is included. A high-temperature resistant layer is fixedly installed on the inner wall of the protective tube body, and an insulating layer is fixedly installed on the inner wall of the high-temperature resistant layer. Connecting discs are fixedly installed at both ends of the protective tube body. A cavity is formed inside one of the connecting discs, and a sliding rod is slidably arranged inside the cavity. A limiting plate is fixedly installed at the bottom of the sliding rod, and a slider is fixedly installed at the outer end of the sliding rod. A locking block is fixedly installed on the inner wall of the slider. A slot for cooperating with the locking block is formed on the connecting disc on the other side. A first spring is sleeved on the outer side of the sliding rod. One end of the first spring is fixedly connected to the inner wall of the cavity, and the other end of the first spring is fixedly connected to the limiting plate at the bottom of the sliding rod. Limiting rods are symmetrically fixedly installed on the front and rear sides of the slider. A moving block is slidably arranged on the limiting rod, and an insert block is fixedly installed on the side wall of the moving block. A slot for cooperating with the insert block is formed on the side wall of the connecting disc. A second spring is sleeved on the outer side of the limiting rod. One end of the second spring is fixedly connected to the moving block, and the other end of the second spring is fixedly connected to the slider.

[0006] Preferably, the insulating layer is further provided with a plurality of slots, and a telescopic spring is fixedly installed inside the slot, with a clamping plate fixedly installed at one end of the telescopic spring.

[0007] Preferably, an installation block is also fixedly installed on the side wall of the protective pipe body. A fixing block is detachably installed on the installation block by fastening bolts. A support rod is fixedly installed on the fixing block. An installation plate is fixedly installed at the top end of the support rod. A plurality of threaded holes are evenly opened on the installation plate. Installation bolts are installed in the threaded holes by threaded connection.

[0008] Preferably, a handle is fixedly installed on the top of the movable block.

[0009] Preferably, one side of the connecting plate also has an installation cavity, a sliding plate is slidably disposed inside the installation cavity, an insertion rod is fixedly installed on the side wall of the sliding plate, and a limiting groove is provided on the card block to cooperate with the insertion rod.

[0010] Preferably, a telescopic rod is also fixedly installed inside the mounting cavity, and the end of the telescopic arm of the telescopic rod is fixedly connected to the slide plate.

[0011] Preferably, a third spring is sleeved on the outer side of the telescopic rod, one end of the third spring is fixedly connected to the slide plate, and the other end of the third spring is fixedly connected to the mounting cavity.

[0012] Preferably, the bottom of the mounting plate is symmetrically fixed with arc-shaped support blocks.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the protective tube body is provided with a high-temperature resistant layer and an insulating layer. The high-temperature resistant layer enables the protective tube to maintain stable physical properties in high-temperature environments, avoiding softening and deformation due to high temperatures that would affect the protection of the cable and extend the cable's service life. The insulating layer effectively ensures the insulation performance of the cable, prevents leakage accidents, ensures the safety of personnel and equipment, and has stable performance, making it resistant to moisture and chemical corrosion. Through the cooperation of the sliding rod, slider, and locking block in one side of the connecting plate with the locking groove of the other side of the connecting plate, as well as the elastic action of the first spring, a fast and reliable connection is achieved. The operation is simple, and the connection is stable and not easy to loosen. At the same time, the setting of the moving block and insertion block on the slider and the slot on the side wall of the connecting plate, in conjunction with the second spring, further enhances the reliability of the connection, providing double protection to prevent separation at the connection point. Furthermore, the installation cavity, sliding plate, insertion rod, and upper limit slot of the locking block inside the connecting plate on one side, as well as the setting of the telescopic rod and the third spring, add an additional locking mechanism to the connection, making the connection more stable and adaptable to various complex environments and external forces. In addition, the slots opened on the insulation layer and the installation of telescopic springs and clamping plates can automatically adjust the clamping force according to the thickness of the cable, stably clamp the cable, prevent the cable from shaking inside the protective tube, reduce the friction between the cable sheath and the inner wall of the protective tube, protect the insulation performance and mechanical strength of the cable, and ensure stable power transmission.

[0014] Furthermore, the protective pipe's sidewall mounting blocks, fixing blocks, support rods, and mounting plates allow for secure installation on various support structures via fastening bolts and mounting bolts. This flexible installation method adapts to different installation scenarios. The arc-shaped support block at the bottom of the mounting plate increases the contact area between the mounting plate and the support structure, improving installation stability, enabling it to withstand greater external forces, and ensuring the protective pipe remains in place during long-term use, providing continuous and reliable protection for the cable.
