Description

Technical Field

[0001] This utility model relates to the field of shielded control cable technology, and in particular to a high-temperature resistant shielded control cable. Background Technology

[0002] In the field of blasting engineering, shielded control cables are cables specifically designed to ensure the accurate transmission of various control signals during blasting operations. Their main components include a conductor, an insulation layer, a shielding layer, and a protective outer layer, ensuring that blasting control signals can be transmitted accurately even in complex electromagnetic environments, and guaranteeing that blasting operations are carried out safely and precisely according to the predetermined plan.

[0003] High-temperature shielded control cables are a type of cable specially designed for use in high-temperature environments, based on ordinary shielded control cables. In addition to the shielding function of ordinary shielded control cables, the insulation and sheathing materials have been optimized and improved, enabling them to maintain good electrical and physical properties in high-temperature environments. They can work stably in high-temperature workplaces and provide reliable protection for equipment control and signal transmission in high-temperature environments.

[0004] Traditional cables use high-temperature resistant insulation materials to cope with high-temperature environments. However, when exposed to high temperatures for a long time, the insulation materials will gradually age and their insulation performance will decline. Existing technologies slow down the aging rate of insulation materials by setting heat dissipation channels inside the insulation layer. However, in actual use, the heat dissipation mechanism of existing high-temperature shielded control cables is a narrow gap reserved between the insulation layer and the shielding layer. This single channel cannot effectively cope with the large amount of heat generated by the cable during operation, resulting in heat accumulation inside the cable and an increase in temperature.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 2 Figure 3 and Figure 4This utility model provides an embodiment of a high-temperature shielded control cable, comprising a conductor 1, which serves as a current transmission carrier, providing conductivity for the cable. A heat dissipation mechanism 2 is provided on the outside of the conductor 1 to dissipate the heat generated during cable operation, ensuring stable cable operation. The heat dissipation mechanism 2 includes a first heat dissipation channel 201, which initially guides the heat generated by the conductor 1, forming a heat dissipation path. The inner wall of the first heat dissipation channel 201 is fixedly connected to the outer wall of the conductor 1, closely fitting the conductor 1 and effectively conducting heat. Multiple hollow heat-conducting pipes 202 are equidistantly fixedly connected to the inner wall of the first heat dissipation channel 201. The hollow heat-conducting pipes 202 accelerate air convection through their hollow structure, rapidly transferring heat. Multiple heat dissipation fins 203 are equidistantly fixedly connected to the outer walls of the multiple hollow heat-conducting pipes 202, increasing the heat dissipation area and accelerating heat dissipation. Heat dissipation holes 204 are provided on the left and right sides of the multiple heat dissipation fins 203, further promoting air circulation and enhancing the heat dissipation effect. A second heat dissipation channel 205 is fixedly connected to the outer wall of channel 201. The second heat dissipation channel 205 further optimizes the heat dissipation path and enhances the heat dissipation capacity. A spiral heat dissipation strip 206 is fixedly connected to the inner wall of the second heat dissipation channel 205. The spiral heat dissipation strip 206 guides heat transfer with a spiral structure, prolongs the heat dissipation time, and improves the heat dissipation efficiency. The heat dissipation mechanism 2 is used to dissipate heat from the cable. By integrating various components, it achieves a high-efficiency heat dissipation function. A shielding protection component 4 is set on the outside of the heat dissipation mechanism 2. The shielding protection component 4 blocks external electromagnetic interference and protects the internal signal transmission of the cable. The shielding protection component 4 includes a shielding composite layer 401. The shielding composite layer 401 mainly undertakes the function of shielding external electromagnetic signals. The inner wall of the shielding composite layer 401 is fixedly connected to the outer wall of the second heat dissipation channel 205 to provide shielding protection. A reinforcing layer 402 is fixedly connected to the outer wall of the shielding composite layer 401. The reinforcing layer 402 enhances the overall mechanical strength of the cable and protects the internal structure. Heat conduction mechanisms 5 are set on both the left and right sides of the conductor 1. The heat conduction mechanisms 5 assist the conductor 1 in conducting heat and optimize the heat dissipation layout.

[0036] Reference Figure 1 and Figure 6The heat conduction mechanism 5 includes two heat conduction blocks 501, which quickly conduct heat away from the conductor 1. The adjacent sides of the two heat conduction blocks 501 are fixedly connected to the left and right sides of the conductor 1, respectively, making close contact with the conductor 1 and efficiently absorbing heat. Heat dissipation blocks 502 are fixedly connected to the opposite sides of the two heat conduction blocks 501, which further diffuse the conducted heat. Multiple corrugated fins 503 are fixedly connected at equal intervals to the opposite sides of the two heat dissipation blocks 502, which increase the heat dissipation area and allow heat to be quickly dissipated to the surrounding environment. The heat conduction mechanism 5 is used for heat conduction. Through the cooperation of various components, a good heat conduction function is achieved. Sealing mechanisms 3 are provided on the left and right sides of the shielding and protection component 4. Sealing mechanisms 3 prevent external moisture and dust from entering and protect the internal structure of the cable. Sealing mechanisms 3 are used to seal the cable and ensure the stability of the internal environment of the cable.

[0037] Specifically, during cable operation, conductor 1 generates heat due to current flow. At this time, the heat dissipation mechanism 2 plays a crucial role. The hollow heat-conducting pipe 202 in the first heat dissipation channel 201 accelerates air convection due to its hollow structure, quickly transferring the heat generated by conductor 1 to the heat dissipation fins 203. The heat dissipation fins 203 increase the heat dissipation area, and the heat dissipation holes 204 on its left and right sides further promote air circulation and accelerate heat dissipation. At the same time, the spiral heat dissipation strip 206 in the second heat dissipation channel 205 guides heat along the spiral path through its unique spiral structure, increasing the heat dissipation path and time, and enhancing the heat dissipation effect. The heat-conducting mechanism 5 on the left and right sides of conductor 1, with two heat-conducting blocks 501 directly connected to conductor 1, can quickly conduct heat to the heat dissipation block 502. The wave fins 503 on the heat dissipation block 502 further expand the heat dissipation area and dissipate heat to the surrounding environment. The shielding and protection component 4 not only plays a shielding role, but the reinforcing layer 402 also enhances the overall mechanical properties of the cable, effectively dealing with the large amount of heat generated during cable operation, avoiding heat accumulation, reducing the internal temperature of the cable, and ensuring stable cable operation.

[0038] Reference Figure 5 Figure 6 and Figure 7The sealing mechanism 3 includes two fixing rings 301, providing an installation position. The inner walls of the two fixing rings 301 are respectively fixedly connected to the left and right sides of the outer wall of the reinforcing layer 402, securing the sealing mechanism 3 to the reinforcing layer 402 of the cable and enhancing the overall sealing performance. Positioning blocks 303 are fixedly connected to the upper and lower sides of the two fixing rings 301, providing positioning and engagement positions to ensure accurate connection. Locking grooves 304 are provided on the outer sides of the multiple positioning blocks 303, cooperating with locking blocks 3061 to achieve a locking connection between the fixing rings 301 and the sealing caps 302. Sealing caps 302 are slidably connected to the outer walls of the two fixing rings 301, directly blocking external moisture and dust, thus achieving a sealing effect. Fixing blocks 305 are fixedly connected to the upper and lower sides of the sealing caps 302, providing a sealing effect. Provided with installation space, the inner walls of the two sealing caps 302 are fixedly connected to the corresponding heat sinks 502, connecting the sealing mechanism 3 to the heat sink mechanism 2, enhancing the overall structural stability. Each of the two fixing blocks 305 has a locking component 306 inside to lock the sealing cap 302 to the fixing ring 301, ensuring sealing reliability. Each of the two fixing blocks 305 has an unlocking component 307 on its opposite side to release the lock, facilitating disassembly and adjustment of the sealing mechanism 3. The locking component 306 includes two locking blocks 3061 that cooperate with the locking grooves 304 of the positioning block 303 for a fixed connection. The outer walls of the two locking blocks 3061 are slidably connected to the inner walls of the corresponding positioning blocks 303, allowing for flexible locking and unlocking actions. Each locking block 3061 has a pull rod 3062 fixedly connected to its opposite side to control the movement of the locking block 3061, thus enabling locking and unlocking operations. Springs 3063 are slidably connected to the outer walls of both pull rods 3062 to provide elastic force to the locking block 3061, keeping it locked. The outer walls of the two springs 3063 are slidably connected to the inner walls of their respective fixed blocks 305 to ensure stable operation and provide stable elastic force. The unlocking assembly 307 includes two moving blocks 3071 as trigger components for the unlocking operation, driving other components to move. One side of each moving block 3071 is slidably connected to the other end of its corresponding pull rod 3062 to transmit the unlocking force, causing the locking block 3061 to disengage from the locking groove 304. Each movable block 3071 has an unlocking slider 3072 fixedly connected to one of its adjacent sides to guide the unlocking action and ensure accurate operation. The bottom of each unlocking slider 3072 has a locking groove 3075 that engages with a locking block 3074 to fix the position of the unlocking slider 3072. The right ends of the opposite sides of each of the two fixed blocks 305 have sliding grooves 3073 to provide a sliding track for the unlocking slider 3072, allowing it to move smoothly. The inner walls of the two sliding grooves 3073 are slidably connected to the outer walls of the corresponding unlocking sliders 3072 to ensure smooth sliding. The opposite sides of each of the two locking grooves 3075 are fixedly connected with locking blocks 3074 that engage with the locking grooves 3075 to fix the unlocking slider 3072 and stabilize the unlocked state.The outer walls of the two locking blocks 3074 engage with the inner walls of their corresponding locking slots 3075 to secure the unlocking slider 3072.

[0039] Specifically, during cable sealing installation, firstly, the two fixing rings 301 are respectively fitted onto the left and right sides of the outer wall of the reinforcing layer 402. At this time, the positioning blocks 303 on the upper and lower sides of the fixing rings 301 are in the corresponding positions. The sealing cap 302 with fixing blocks 305 is slid along the outer wall of the fixing rings 301, so that the locking components 306 in the upper and lower fixing blocks 305 of the sealing cap 302 are aligned with the positioning blocks 303. Under the elastic force of the spring 3063, the locking block 3061 slides outward and is locked into the locking groove 304 on the inner wall of the positioning block 303, thereby tightly connecting the sealing cap 302 and the fixing rings 301. At the same time, the inner wall of the sealing cap 302 is fixed to the heat sink 502, so that the entire sealing mechanism 3 is stably connected to the other structures of the cable, achieving a seal on the cable, effectively preventing external moisture and dust from entering, and protecting the internal structure of the cable. When it is necessary to disassemble and adjust the cable components, the unlocking component 307 is opened. When the mechanism begins to function, it pushes the moving block 3071 from the side away from the fixed ring 301. The moving block 3071 drives the unlocking slider 3072 connected to it to slide within the slide groove 3073. During the movement of the unlocking slider 3072, it pulls the pull rod 3062 that is slidably connected to it. The pull rod 3062 overcomes the elastic force of the spring 3063, causing the locking block 3061 to disengage from the locking groove 304 of the positioning block 303, thereby releasing the locking connection between the sealing cap 302 and the fixed ring 301. During this process, the locking block 3074 engages with the engaging groove 3075, which can fix the position of the unlocking slider 3072 and ensure that the unlocking operation is stable. After the operation is completed, the moving block 3071 is released, the locking block 3074 separates from the engaging groove 3075, and the spring 3063 pushes the pull rod 3062 and the locking block 3061 to reset, so that they can be used for sealing next time. This realizes the convenience and reliability of cable sealing and ensures the stable operation of the cable.

[0040] Reference Figure 6 and Figure 7 The inner walls of the two locking grooves 304 are fixedly connected with sealing rings 6 to enhance the sealing performance of the sealing mechanism 3 and prevent external moisture and dust from entering. The left side of the two sealing rings 6 respectively fits with the right side of the corresponding fixing ring 301 to ensure that the sealing rings 6 and the fixing ring 301 are in close contact and effectively block external substances. The two pull rods 3062 are fixedly connected with limit sliders 7 at their opposite ends to limit the movement range of the pull rods 3062. The outer walls of the two limit sliders 7 are slidably connected with the inner walls of the corresponding moving blocks 3071 so that the pull rods 3062 can slide stably within the moving blocks 3071 and ensure the smooth progress of the unlocking operation.

[0041] Specifically, when the sealing mechanism 3 is assembled, the sealing ring 6 and the fixed ring 301 fit tightly together to achieve a good seal. The limiting slider 7 at the end of the pull rod 3062 slides within the moving block 3071 to limit the stroke of the pull rod 3062, ensuring that the unlocking and locking operations are stable and reliable.

[0042] Working principle: During cable operation, conductor 1 generates heat due to current flow. At this time, heat dissipation mechanism 2 plays a key role. The hollow heat-conducting pipe 202 in the first heat dissipation channel 201 accelerates air convection due to its hollow structure, quickly transferring the heat generated by conductor 1 to heat dissipation fins 203. Heat dissipation fins 203 increase the heat dissipation area, and the heat dissipation holes 204 on its left and right sides further promote air circulation and accelerate heat dissipation. At the same time, the spiral heat dissipation strip 206 in the second heat dissipation channel 205 guides heat along the spiral path through a unique spiral structure, increasing the heat dissipation path and time, and enhancing the heat dissipation effect. The heat conduction mechanism 5 on the left and right sides of conductor 1 has two heat conduction blocks 501 directly connected to conductor 1, which can quickly conduct heat to heat dissipation block 502. The wave fins 503 on heat dissipation block 502 further expand the heat dissipation area and dissipate heat to the surrounding environment. The shielding and protection component 4 not only plays a shielding role, but the reinforcing layer 402 also enhances the overall mechanical properties of the cable, effectively copes with the large amount of heat generated during cable operation, avoids heat accumulation, reduces the internal temperature of the cable, and ensures stable cable operation.

[0043] Furthermore, during cable sealing installation, firstly, the two fixing rings 301 are respectively fitted onto the left and right sides of the outer wall of the reinforcing layer 402. At this time, the positioning blocks 303 on the upper and lower sides of the fixing rings 301 are in the corresponding positions. The sealing cap 302 with the fixing block 305 is slid along the outer wall of the fixing ring 301, so that the locking component 306 in the upper and lower fixing blocks 305 of the sealing cap 302 is aligned with the positioning block 303. Under the elastic force of the spring 3063, the locking block 3061 slides outward and is locked into the locking groove 304 on the inner wall of the positioning block 303, thereby tightly connecting the sealing cap 302 and the fixing ring 301. At the same time, the inner wall of the sealing cap 302 is fixed to the heat sink 502, so that the entire sealing mechanism 3 is stably connected to the other structures of the cable, achieving a seal on the cable, effectively preventing external moisture and dust from entering, and protecting the internal structure of the cable. When it is necessary to disassemble and adjust the cable components, the unlocking component 307 is activated. The mechanism functions by pushing the movable block 3071 away from the fixed ring 301. The movable block 3071 drives the unlocking slider 3072 connected to it to slide within the slide groove 3073. During the movement of the unlocking slider 3072, it pulls the pull rod 3062 that is slidably connected to it. The pull rod 3062 overcomes the elastic force of the spring 3063, causing the locking block 3061 to disengage from the locking groove 304 of the positioning block 303, thereby releasing the locking connection between the sealing cap 302 and the fixed ring 301. During this process, the locking block 3074 engages with the engaging groove 3075, which can fix the position of the unlocking slider 3072 and ensure that the unlocking operation is stable. After the operation is completed, the movable block 3071 is released, the locking block 3074 separates from the engaging groove 3075, and the spring 3063 pushes the pull rod 3062 and the locking block 3061 to reset, so that they can be used for sealing next time. This realizes the convenience and reliability of cable sealing and ensures the stable operation of the cable.
