Description

Technical Field

[0001] This utility model relates to the field of power cable protection technology, and more specifically, to a cable protection pipe with good heat dissipation effect. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent them from being damaged. Cables generate a certain amount of heat during operation. If the heat cannot be dissipated in time, it will cause the cable temperature to rise, which will affect the performance and life of the cable.

[0003] A search revealed that Chinese Patent Publication No. CN214674085U discloses "an easy-to-install heat-dissipating cable protection pipe, relating to the field of cable protection pipe technology. Its key technical points are: it includes a base, a protection pipe, and a heat dissipation pipe; the top of the base has a groove matching the protection pipe; the protection pipe is placed in the groove; the base has a fixing bolt penetrating the top and bottom of the base; the heat dissipation pipe is sleeved inside the protection pipe; both the top of the protection pipe and the top of the heat dissipation pipe have mounting grooves, and each mounting groove has a matching connecting device, including a connecting seat, a connecting shaft, a connecting arm, a connecting buckle, and a connecting block; the inner wall of the bottom of the heat dissipation pipe has a cable fixing device, including a fixing seat, a fixing shaft, a fixing arm, a magnetic block, and a magnetic seat. This solves the problems of inconvenient installation and poor heat dissipation of existing cable protection pipes. Furthermore, the cable protection pipe is simple and convenient to install, improving construction efficiency." However, it still has the following drawbacks:

[0004] (1) Although the device can dissipate heat from the cable, the heat dissipation tube is installed inside the protective tube. This design may cause the heat to be hindered during the transfer process. The heat dissipation tube may not be able to quickly dissipate the heat to the external environment. After long-term use, dust or debris may accumulate inside the heat dissipation tube, affecting the heat dissipation effect and making it inconvenient to disassemble.

[0005] (2) Although the magnetic block and magnetic base of this device are convenient to fix, they may also cause the cable to loosen or shift when subjected to external forces, especially in environments with large vibrations or impacts. Therefore, a cable protection tube with good heat dissipation is proposed. Utility Model Content

[0006] The purpose of this utility model is to address the problem that while the existing cable protection pipe with good heat dissipation effect can dissipate heat from the cable, the heat dissipation pipe is installed inside the protection pipe. This design may cause some obstacles in the heat transfer process, and the heat dissipation pipe may not be able to quickly dissipate heat to the external environment. In addition, after long-term use, dust or debris may accumulate inside the heat dissipation pipe, affecting the heat dissipation effect and making it inconvenient to disassemble.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a cable protection tube with good heat dissipation effect, including a semi-circular tube, wherein a heat dissipation mechanism for facilitating the dissipation of cable heat is provided on one side of the semi-circular tube, and two fixing components for fixing the cable inside the tube are provided on the side wall of the semi-circular tube.

[0009] The heat dissipation mechanism includes a semi-circular component fixedly connected to the inner wall of a semi-circular tube. A rectangular plate is fixedly connected to the side wall of the semi-circular component. A heat dissipation hole is opened on the side wall of the rectangular plate. A heat dissipation fin is fixedly connected to one side of the rectangular plate. Fixing members are fixedly connected to the top and bottom of the semi-circular component. Fixing holes are opened on the side walls of the two fixing members. A fixing rod is threaded into the inside of the fixing hole. A positioning member is rotatably connected to the outside of the fixing rod. Holes are opened on the top and bottom side walls of the rectangular plate and the heat dissipation fin, and are threadedly connected to the fixing rod.

[0010] As a preferred technical solution of this utility model, the fixing component includes a connector fixedly connected to the side wall of the semi-circular tube. A bolt is threadedly connected to the side wall of the connector. A rotating handle is welded to the side wall of one end of the bolt. A through hole is opened on the outer wall of the semi-circular tube. A moving rod is slidably connected to the inner wall of the through hole. A limit block is fixedly connected to one end of the moving rod. An arc-shaped plate is fixedly connected to the other end of the moving rod. A spring is fixedly connected to the side of the arc-shaped plate near the bolt and is fixedly connected to the inner wall of the semi-circular tube.

[0011] As a preferred technical solution of this utility model, the outer wall of the semi-circular part is provided with a plurality of wire feeding holes, the inner wall of the wire feeding holes is provided with four rotating grooves, and ball bearings are rotatably connected to the inner walls of the four rotating grooves.

[0012] As a preferred technical solution of this utility model, a fireproof layer is provided on the inner wall of the semi-circular tube, and the fireproof layer is made of aluminum hydroxide.

[0013] As a preferred technical solution of this utility model, a temperature sensor is provided on the inner wall of the semi-circular tube, and an alarm is provided on the outer wall of the fixing member, and the temperature sensor is electrically connected to the alarm.

[0014] As a preferred technical solution of this utility model, an elastic pad is provided on the side wall of the arc plate away from the spring, and the elastic pad is made of silicone.

[0015] As a preferred technical solution of this utility model, the rectangular plate and the heat dissipation fins are made of aluminum alloy.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Through the heat dissipation mechanism, when the cable generates heat during operation, the heat is first transferred to the inner wall of the semi-circular tube that is in direct contact with the cable. The heat is then further conducted to the semi-circular component. The semi-circular component acts as an intermediate medium for heat conduction, dispersing the heat to the rectangular plate and heat dissipation fins connected to it. This increases the heat dissipation area, promotes air circulation, improves heat dissipation efficiency, enhances structural stability and installation convenience, and extends the service life of the cable.

[0018] 2. With the fixed components in place, the operator rotates the bolt by turning the handle. The end of the bolt gradually approaches the arc-shaped plate. As the bolt moves, it pushes the arc-shaped plate towards the cable, while simultaneously causing the moving rod to slide within the hole. During the movement of the arc-shaped plate, the spring is gradually compressed. The spring force and the thrust of the bolt work together to make the arc-shaped plate tightly clamp the cable, thus fixing the cable. This allows for flexible fixing and loosening of the cable, reducing the impact force on the cable and protecting it from damage. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0026] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 As shown, this embodiment proposes a cable protection pipe with good heat dissipation effect, including a semi-circular pipe 1. A heat dissipation mechanism 2 is provided on one side of the semi-circular pipe 1 to facilitate the dissipation of cable heat. Two fixing components 3 for fixing the cable inside the pipe are provided on the side wall of the semi-circular pipe 1.

[0030] like Figure 3As shown, the heat dissipation mechanism 2 includes a semi-circular component 201 fixedly connected to the inner wall of the semi-circular tube 1. A rectangular plate 202 is fixedly connected to the side wall of the semi-circular component 201. A heat dissipation hole 203 is provided on the side wall of the rectangular plate 202. The rectangular plate 202 provides an installation position for the heat dissipation hole 203. The heat dissipation hole 203 can increase air circulation and promote heat dissipation, thereby improving heat dissipation efficiency. A heat dissipation fin 204 is fixedly connected to one side of the rectangular plate 202. The heat dissipation fin 204 increases the heat dissipation area. When air flows through the heat dissipation fin 204, it will carry away more heat, further improving heat dissipation efficiency. Fixing members 205 are fixedly connected to the top and bottom of the semi-circular component 201. Fixing holes 206 are provided on the side walls of the two fixing members 205. A fixing rod 207 is threadedly connected inside the fixing hole 206. A positioning member 2 is rotatably connected to the outside of the fixing rod 207. 08. Holes 209 are provided on the top and bottom sidewalls of the rectangular plate 202 and the heat dissipation fins 204, and are threadedly connected to the fixing rods 207. The holes 209 allow the fixing rods 207 to pass through. Under the action of the fixing holes 206 and the fixing rods 207, the rectangular plate 202 and the heat dissipation fins 204 are firmly fixed to the fixing member 205. When the cable generates heat during operation, the heat is first transferred to the inner wall of the semi-circular tube 1, which is in direct contact with the cable. Since the semi-circular member 201 is fixedly connected to the inner wall of the semi-circular tube 1, the heat will be further conducted to the semi-circular member 201. The semi-circular member 201 acts as an intermediate medium for heat conduction, dispersing and transferring the heat to the rectangular plate 202 and the heat dissipation fins 204 connected to it. This increases the heat dissipation area, promotes air circulation, improves heat dissipation efficiency, enhances structural stability and installation convenience, and extends the service life of the cable.

[0031] like Figure 4 and Figure 5As shown, the fixing assembly 3 includes a connector 301 fixedly connected to the side wall of the semicircular tube 1. The connector 301 provides an installation and fixing platform. A bolt 302 is threaded onto the side wall of the connector 301. By rotating the bolt 302, its position on the connector 301 can be changed. A rotating handle 303 is welded to the side wall of one end of the bolt 302. The rotating handle 303 provides a convenient point of force application for the operator. A through hole 304 is opened on the outer wall of the semicircular tube 1. A moving rod 3 is slidably connected to the inner wall of the through hole 304. 05. The perforation 304 provides a guide track for the movement of the moving rod 305, ensuring that the moving rod 305 can move linearly in a specific direction. The moving rod 305 plays the role of transmitting power. One end of the moving rod 305 is fixedly connected to a limit block 306, which prevents the moving rod 305 from falling out of the perforation 304 during sliding. The other end of the moving rod 305 is fixedly connected to an arc-shaped plate 307. The arc-shaped plate 307 can better fit the outer surface of the cable, increasing the contact area with the cable, thereby providing... For a more stable and reliable fixing effect, a spring 308 is fixedly connected to the side of the arc-shaped plate 307 near the bolt 302, and is also fixedly connected to the inner wall of the semi-circular part 201. The spring 308 provides elastic restoring force and has a certain buffering effect. When it is necessary to put the cable into the protective tube and fix it, the operator rotates the bolt 302 by turning the handle 303. The end of the bolt 302 gradually approaches the arc-shaped plate 307. As the bolt 302 moves, it pushes the arc-shaped plate 307 towards the cable, and at the same time drives the moving rod 3. 05 Slides within the perforation 304. During the movement of the arc plate 307, the spring 308 is gradually compressed. When the arc plate 307 moves to close contact with the cable, under the continuous thrust of the bolt 302, the spring 308 is further compressed, thereby generating a reverse elastic force. This elastic force, together with the thrust of the bolt 302, makes the arc plate 307 tightly clamp the cable, thus fixing the cable. It can flexibly fix and loosen the cable, reduce the impact force on the cable, and protect the cable from damage.

[0032] like Figure 1 As shown, the outer wall of the semi-circular part 201 is provided with multiple cable release holes 4, and the inner wall of the cable release hole 4 is provided with four rotating grooves 5. The inner walls of the four rotating grooves 5 are rotatably connected with ball bearings 6. The cable release hole 4 allows multiple cables to pass through the protective tube independently, avoiding the cables from getting tangled or squeezed together. The ball bearings 6 reduce friction, making it easier to thread the cables, thus reducing construction time and labor costs.

[0033] like Figure 1 As shown, a fireproof layer 7 is provided on the inner wall of the semi-circular tube 1. The fireproof layer 7 is made of aluminum hydroxide. The fireproof layer 7 reduces the ambient temperature by absorbing heat and delays the thermal decomposition of the cable insulation material.

[0034] like Figure 2As shown, a temperature sensor 8 is installed on the inner wall of the semi-circular tube 1, and an alarm 9 is installed on the outer wall of the fastener 205. The temperature sensor 8 and the alarm 9 are electrically connected. The temperature sensor 8 can sense the surface temperature of the cable in real time during operation and convert it into an electrical signal to be transmitted to the alarm 9, ensuring that the risk is detected in time, improving maintenance efficiency and extending the service life of the cable.

[0035] like Figure 2 As shown, an elastic pad 10 is provided on the side wall of the arc plate 307 away from the spring 308. The elastic pad 10 is made of silicone. When the arc plate 307 is impacted by an external force, the elastic pad 10 can absorb the impact energy through elastic deformation, thus avoiding structural damage caused by hard contact.

[0036] like Figure 1 As shown, the rectangular plate 202 and the heat dissipation fins 204 are made of aluminum alloy. The aluminum alloy heat dissipation fins 204 can improve the heat transfer speed and accelerate the cooling of the cable.

[0037] Specifically, when using this cable protection pipe with good heat dissipation: the operator rotates the handle 303 to rotate the bolt 302. The end of the bolt 302 gradually approaches the arc-shaped plate 307. As the bolt 302 moves, it pushes the arc-shaped plate 307 towards the cable, simultaneously causing the moving rod 305 to slide within the through hole 304. During the movement of the arc-shaped plate 307, the spring 308 is gradually compressed. When the arc-shaped plate 307 moves to close contact with the cable, under the continuous thrust of the bolt 302, the spring 308 is further compressed, generating a reverse elastic force. This elastic force, together with the thrust of the bolt 302, causes the arc-shaped plate 307 to tightly clamp the cable, thus fixing the cable (e.g., ...). Figure 4 and Figure 5 As shown), when the cable generates heat during operation, the heat is first transferred to the inner wall of the semicircular tube 1, which is in direct contact with the cable. Since the semicircular component 201 is fixedly connected to the inner wall of the semicircular tube 1, the heat is further conducted to the semicircular component 201. The semicircular component 201 acts as an intermediate medium for heat conduction, dispersing the heat to the rectangular plate 202 and the heat dissipation fins 204 connected to it, thereby improving the heat dissipation efficiency (e.g., ...). Figure 3 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
