Description

Technical Field

[0001] This application relates to the field of power equipment technology, specifically to a power cable connection structure. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, and internal power supply in industrial and mining enterprises. The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system, including power cables of various voltage levels from 1 to 500KV and above, and various types of insulation.

[0003] An existing patent (publication number: CN211046397U) discloses a power cable connection structure, including a wiring part. Both sides of the wiring part are provided with integrally formed protrusions. The wiring part is provided with a cable groove communicating with the two protrusions. A lead screw is inserted into the top wall of each of the two protrusions. A fixing groove is provided inside each of the two protrusions. A fixing block is fixedly installed on the inner top wall of the fixing groove. The lead screw passes through the fixing block. A stop plate is fixedly connected to the end of the lead screw away from the fixing block. Two symmetrical rotating rods are rotatably connected to the inner top wall of the fixing groove.

[0004] The aforementioned comparative document points out that the device uses a lead screw and ball nut to drive two rotating rods to push the clamping ring inward, thereby clamping the cable tightly and preventing it from slipping due to tension. By placing the cable joint part in the cable trough and fixing the cables at both ends of the joint, the stress position of the cable under tension is transferred, effectively preventing the cable joint from loosening or even falling off. However, the device does not provide sufficient protection for the connection end between the two cables and cannot effectively prevent the ingress of moisture and dust. In power systems, the cable connection end is an extremely critical part, and its performance and stability are directly related to the safe operation of the entire system. If the connection end is corroded by moisture and dust, it may lead to a series of problems such as poor connection, short circuit, and decreased insulation performance, and in severe cases, it may even cause safety accidents such as fires. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a power cable connection structure that offers advantages such as protecting the cable connection ends. This solves the problem that the existing device does not provide sufficient protection for the connection ends between two cables and cannot effectively prevent the ingress of moisture and dust. In power systems, cable connection ends are extremely critical components, and their performance and stability directly affect the safe operation of the entire system. If the connection ends are corroded by moisture and dust, it may lead to a series of problems such as poor connection, short circuit, and decreased insulation performance. In severe cases, it may even cause safety accidents such as fires.

[0006] To achieve the above objectives, this application provides the following technical solution: a power cable connection structure, comprising a first cable and a second cable, wherein a first connector is fixedly connected to the outer wall of the first cable, a first baffle is fixedly connected inside the first connector, straight tubes are arranged in a circular array on the surface of the first baffle, a temperature sensor is fixedly connected to the surface of the first baffle, a threaded ring is fixedly connected to one end of the outer wall of the first connector, a first slide rail is fixedly connected to the outer wall of the first connector, a rotating plate is slidably arranged on the outer wall of the first slide rail, and two through holes are opened inside the rotating plate; a second connector is fixedly connected to the outer wall of the second cable, a second baffle is fixedly connected inside the second connector, a plurality of plug pins are fixedly connected to the surface of the second baffle in a circular array, a second slide rail is fixedly connected to the outer wall of the second connector, a threaded sleeve is slidably connected to the outside of the second slide rail, and two fixed seats are fixedly connected to the outer wall of the threaded sleeve in a mirror-shaped arrangement, each fixed seat having a threaded hole inside.

[0007] The above solution utilizes a temperature sensor installed inside the first connector to monitor temperature changes at the cable connection in real time, preventing safety issues such as cable overheating and short circuits. The temperature sensor also allows maintenance personnel to promptly detect and address potential overheating problems, ensuring the stable operation of the power system. This connection structure, through the combination of threaded rings and threaded sleeves, along with the fixing method of the mounting base and threaded holes, achieves a dual connection structure, enhancing connection stability and improving sealing performance. This prevents moisture, dust, and other impurities from entering the cable connection, avoiding cable failures caused by environmental factors and extending cable lifespan. Furthermore, its strong tensile strength ensures the stability and reliability of the cable connection even under harsh environmental conditions such as strong winds and heavy rain, preventing cable loosening or breakage due to tensile forces. The device features real-time monitoring and early warning functions, and its dual connection and strong sealing performance increase the service life of the cable connection.

[0008] Furthermore, three sealing rings are fixedly connected to the inner wall of the threaded ring.

[0009] The above solution effectively prevents moisture, dust, and other impurities from entering the cable connection through the tiny gap between the threaded ring and the cable. The sealing ring not only provides a sealing function but also increases the friction between the threaded ring and the cable, thereby improving the stability of the connection.

[0010] Furthermore, each of the two through holes is slidably connected with a fixing bolt, and a section of the thread of each fixing bolt passing through the through hole is set inside the threaded hole.

[0011] With the above solution, the fixing bolt passes through the through hole and is threaded into the threaded hole, which realizes the tight connection between the first connector and the second connector, preventing the cable connection from loosening or falling off when subjected to external force, thereby enhancing the stability of the connection.

[0012] Furthermore, a communication interface is fixedly connected to the outer wall of the first connector, and a sealing cap is provided on the external thread of the communication interface.

[0013] The addition of a communication interface through the above scheme makes the connection structure more intelligent. By connecting with devices such as remote monitoring systems, the temperature at the cable connection can be monitored in real time, and the data can be transmitted to the remote monitoring system. This helps to detect and deal with potential faults in a timely manner, and improves the reliability and safety of the power system.

[0014] Furthermore, all of the aforementioned connector pins are slidably disposed inside the straightening tube.

[0015] With the above solution, the plug pins are slidably disposed inside the straight tube, making it easier for the second connector to mate with the first connector. The plug pins can achieve tight contact in the straight tube, which helps to reduce the resistance at the connection point, improve the current transmission efficiency, and enhance the stability of the connection.

[0016] Furthermore, the second connector is slidably disposed inside the threaded ring, and all three sealing rings are disposed between the threaded ring and the second connector.

[0017] The above solution simplifies the installation process by using a sliding second connector, making it easier for maintenance personnel to connect cables. The sealing ring on the threaded ring and the second connector prevents moisture, dust, and other impurities from entering the cable connection.

[0018] Furthermore, the threaded sleeve is threaded on the outer wall of the threaded ring.

[0019] The above solution provides a reliable connection between the threaded sleeve and the threaded ring. By rotating the threaded sleeve, it can be tightly fixed on the threaded ring, thereby ensuring a firm connection between the second connector and the first connector and helping to prevent the cable connection from loosening due to vibration or external force.

[0020] Furthermore, all of the aforementioned straight tubes and pins are made of copper.

[0021] The above solution utilizes copper, a material with high electrical conductivity and low resistivity, to ensure smooth current transmission between the straight tube and the pin, thereby reducing energy loss, improving power transmission efficiency, and ensuring the stable operation of the power system.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This power cable connection structure utilizes a temperature sensor installed inside the first connector to monitor temperature changes at the cable connection point in real time. This prevents safety issues such as cable overheating and short circuits. The temperature sensor allows maintenance personnel to promptly detect and address potential overheating problems, ensuring the stable operation of the power system. The connection structure achieves a dual connection through the combination of a threaded ring and threaded sleeve, along with the fixing method of a mounting base and threaded holes. This enhances the connection's stability and improves sealing performance, preventing moisture, dust, and other impurities from entering the cable connection point. This avoids cable failures caused by environmental factors, extends the cable's service life, and, through strong tensile strength, ensures the stability and reliability of the cable connection even under harsh environmental conditions such as strong winds and heavy rain, preventing cable loosening or breakage due to tensile forces. The device features real-time monitoring and early warning functions, and its dual connection and strong sealing performance further extend the service life of the cable connection.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a power cable connection structure includes a first cable 1 and a second cable 2. A first connector 3 is fixedly connected to the outer wall of the first cable 1. A first baffle 4 is fixedly connected inside the first connector 3. Straightening tubes 5 are arranged in a ring array on the surface of the first baffle 4. A temperature sensor 6 is fixedly connected to the surface of the first baffle 4. The temperature sensor 6 inside the first connector 3 can monitor the temperature change at the cable connection in real time to prevent safety problems such as cable overheating and short circuits. Through the temperature sensor 6, maintenance personnel can promptly detect and handle potential overheating problems, thereby ensuring the stable operation of the power system. A threaded ring 7 is fixedly connected to one end of the outer wall of the first connector 3. A first slide rail 9 is fixedly connected to the outer wall of the first connector 3. A rotating plate 10 is slidably arranged on the outer wall of the first slide rail 9. The rotating plate 10 has two through holes 11 arranged in a mirror pattern inside. The second cable 2... A second connector 12 is fixedly connected to the outer wall. A second baffle 13 is fixedly connected inside the second connector 12. Multiple plug pins 14 arranged in a ring array are fixedly connected to the surface of the second baffle 13. The straight tube 5 and the plug pins 14 are used to connect the connection ends of the two cables and maintain power transmission. A second slide rail 15 is fixedly connected to the outer wall of the second connector 12. A threaded sleeve 16 is slidably connected to the outside of the second slide rail 15. Two fixed seats 17 arranged in a mirror distribution are fixedly connected to the outer wall of the threaded sleeve 16. Each fixed seat 17 has a threaded hole 18 inside. Through the cooperation of the threaded ring 7 and the threaded sleeve 16, and the fixing method of the fixed seat 17 and the threaded hole 18, a double connection structure is realized, which enhances the stability of the connection, improves the sealing performance, prevents moisture, dust and other impurities from entering the cable connection, avoids cable failure caused by environmental factors, and extends the service life of the cable.

[0032] Please see Figure 1 , Figure 2 and Figure 4Three sealing rings 8 are fixedly connected to the inner wall of the threaded ring 7. The sealing rings 8 can effectively prevent moisture, dust and other impurities from entering the cable connection through the tiny gap between the threaded ring 7 and the cable. The sealing rings 8 not only have a sealing function, but also increase the friction between the threaded ring 7 and the cable, thereby improving the stability of the connection. Fixing bolts 19 are slidably connected inside the two through holes 11. The threaded part of the two fixing bolts 19 passes through the through holes 11 and is set inside the threaded hole 18. The fixing bolts 19 pass through the through holes 11 and are threadedly connected inside the threaded hole 18, realizing the tight connection between the first connector 3 and the second connector 12, preventing the cable connection from loosening or falling off when subjected to external force, thereby enhancing the stability of the connection. A communication interface 20 is fixedly connected to the outer wall of the first connector 3. A sealing cover 21 is set on the external thread of the communication interface 20. The addition of the communication interface 20 makes the connection structure more intelligent. Through connection with equipment such as remote monitoring systems, the temperature of the cable connection can be monitored in real time and the data can be transmitted to the remote monitoring system, which helps to detect and deal with potential faults in a timely manner and improve the reliability and safety of the power system.

[0033] Please see Figure 2 , Figure 3 and Figure 4 Multiple connector pins 14 are slidably disposed inside the straightening tube 5. This slidable placement of the connector pins 14 within the straightening tube 5 allows the second connector 12 to more easily mate with the first connector 3. The connector pins 14 achieve tight contact within the straightening tube 5, helping to reduce resistance at the connection point, improve current transmission efficiency, and enhance connection stability. The second connector 12 is slidably disposed inside the threaded ring 7, with three sealing rings 8 disposed between the threaded ring 7 and the second connector 12. This slidable placement of the second connector 12 simplifies the installation process, making it easier for maintenance personnel to complete cable connection work. The sealing rings 8 between the threaded ring 7 and the second connector 12 prevent moisture, dust, and other impurities from entering. The material enters the cable connection point, and the threaded sleeve 16 is threaded onto the outer wall of the threaded ring 7. The threaded connection between the threaded sleeve 16 and the threaded ring 7 provides a reliable connection method. By rotating the threaded sleeve 16, it can be tightly fixed on the threaded ring 7, thereby ensuring a firm connection between the second connector 12 and the first connector 3. This helps prevent the cable connection from loosening due to vibration or external force. The multiple straight tubes 5 and the plug pins 14 are all made of copper. Copper is a material with strong conductivity and low resistivity, which can ensure smooth current transmission between the straight tubes 5 and the plug pins 14, helping to reduce energy loss, improve power transmission efficiency, and ensure the stable operation of the power system.

[0034] In this embodiment, the power cable connection structure uses a temperature sensor 6 installed inside the first connector 3 to monitor temperature changes at the cable connection in real time. This helps prevent safety issues such as cable overheating and short circuits. The temperature sensor 6 allows maintenance personnel to promptly detect and address potential overheating problems, ensuring the stable operation of the power system. The connection structure achieves a dual connection through the cooperation of the threaded ring 7 and the threaded sleeve 16, and the fixing method of the fixing seat 17 and the threaded hole 18. This enhances the stability of the connection, improves sealing performance, and prevents moisture, dust, and other impurities from entering the cable connection, avoiding cable failures caused by environmental factors and extending the cable's service life. Furthermore, its strong tensile strength ensures the stability and reliability of the cable connection even under harsh environmental conditions such as strong winds and heavy rain, preventing cable loosening or breakage due to tensile forces. This device features real-time monitoring and early warning functions and increases the service life of the cable connection through dual connections and strong sealing performance.

[0035] It should be noted that multiple wires in the first cable 1 are fixedly connected to the straightening tube 5, and multiple wires in the second cable 2 are fixedly connected to the plug pin 14.

[0036] The working principle of the above embodiments is as follows:

[0037] First, the first connector 3 and the second connector 12 are aligned. The second connector 12 is inserted into the threaded ring 7, while ensuring that multiple insertion pins 14 are aligned with the corresponding straight tubes 5. The threaded sleeve 16 is rotated to connect and secure it along the outer wall of the threaded ring 7, and the multiple insertion pins 14 are inserted into the straight tubes 5 to establish power transmission between the first cable 1 and the second cable 2. The sliding adjustment plate 10 is used to allow the fixing bolt 19 to pass through the through hole 11 and be ready to connect with the threaded hole 18. The fixing bolt 19 is inserted through the through hole 11 and rotated to connect it to the threaded hole 18, thereby tightening the first connector 3 and the second connector 12. The sealing ring 8 is placed between the threaded ring 7 and the second connector 12 to ensure good sealing performance. The sealing cover 21 is removed and connected to the remote monitoring system through the communication interface 20. Temperature data is transmitted to the remote monitoring system through the communication interface 20 so that maintenance personnel can promptly detect and handle potential overheating problems. If the remote monitoring system issues an alarm, indicating that there is overheating or other potential problems at the cable connection, the maintenance personnel should immediately go to the site to check and handle the fault.
