Description

Technical Field

[0001] The present invention relates to the technical field of power cable fixing, and in particular to a power cable fixing device that prevents loosening. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. 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 trunk lines of the power system.

[0003] Cables are composed of multiple parts such as conductors, insulation materials, filling materials, and sheaths. They have a complete structural design, so they have strong anti-interference capabilities and high current transmission efficiency. Ordinary wires are composed of a single core and have no structures such as filling materials and sheaths. Therefore, they have poor anti-interference capabilities and limited power transmission. Therefore, cables are more suitable for long-distance power transmission and high-power power transmission, improving the efficiency and reliability of the power system.

[0004] However, the existing power cable fixing device has the following shortcomings: Power cable fixing equipment is mainly suitable for two scenarios. First, the equipment is installed on the tower to complete the routing and fixing of multiple cables. Second, due to the long high-voltage transmission distance, in order to cope with the insufficient length of a single cable, multiple cables need to be docked in pairs. However, the grafting point cannot provide the original wire harness strength, and fixing equipment is needed to assist to avoid falling off. Because high-voltage transmission cables are long and arranged in areas higher than the ground, they will be blown by strong airflow for a long time, which indirectly increases the working load of the fixing equipment. If the outer layer of the cable is oxidized and corroded, the contact strength with the fixing equipment will also decrease. However, the existing cable reinforcement fixing equipment is limited by its own structure and can only provide a relatively single physical support. It is unable to capture the loosening signal generated by the cable grafting in real time, resulting in relevant personnel unable to repair the damaged cables in time, increasing the probability of power accidents.

[0005] Therefore, we propose an anti-loosening power cable fixing device to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an anti-loosening power cable fixing device. When two cables are separated, their outer walls will rub against the corresponding arc-shaped friction-increasing pads from two directions. The large friction force generated will impact the connection strength of the solid rod and the impact rubber sleeve until the impact rubber sleeve body is broken. Each solid rod will generate an outward pulling force, and the tension signal generated by each inductive threaded joint will be captured by a miniature tension sensor. The external force signal is quickly introduced into the receiving electronic controller through the first information line, and the received signal is then introduced into the signal transmitter through the second information line. Finally, the signal transmitter builds a virtual transmission channel with the target terminal, and the induction signal is sent out in time through the enhanced antenna, so that relevant personnel can quickly formulate solutions and perform maintenance to solve the problems raised by the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-loosening power cable fixing device, comprising two groups of cable arc frames, and each group of cable arc frames has two, each of the cable arc frames is welded with a first external plate on both sides of the outer wall, and every two opposite first external plates form a group, every two of the cable arc frames are welded with a second external plate on the opposite side, a micro-tension sensor is provided between the opposite sides of every two of the second external plates, each of the micro-tension sensors is fixedly connected to a group of inductive threaded joints on the two rear sides, each of the outer walls of the inductive threaded joints is rotatably connected to a solid rod, every two of the second external plates are fixedly installed on the opposite sides of the second external plates, and each group The number is equal to that of a group of inductive threaded joints, one end of the outer wall of each solid rod is movably inserted into the interior of a corresponding second external plate, and fixed to a corresponding impact rubber sleeve, a transverse bracket is fixedly installed between the opposite sides of the two groups of the first external plates, a load-bearing support plate is fixedly installed on the top of each transverse bracket, a rectangular frame is fixedly installed inside the load-bearing support plate, a receiving electronic controller is fixedly installed inside the rectangular frame, a signal transmitter is fixedly installed on the top of the load-bearing support plate, a locking joint is fixedly installed on the top of the signal transmitter, an enhanced antenna is fixedly inserted inside the locking joint, and the input end of the enhanced antenna is fixedly connected to the output end of the signal transmitter.

[0008] Preferably, the tops and bottoms of the two miniature tension sensors are fixedly connected to a wiring base, and the top of the receiving electronic controller and one side of the outer wall of the signal transmitter are respectively provided with a first wiring slot and a second wiring slot, and the interior of each wiring base is fixedly connected to a group of first information lines, and the output ends of each group of first information lines are respectively connected to a corresponding first wiring slot, and the interior of the second wiring slot is fixedly connected to a group of second information lines, and the output ends of a group of second information lines are all connected to the wiring terminals of the receiving electronic controller.

[0009] Preferably, a storage battery is fixedly installed on the bottom of one of the load-bearing support plates, and the terminal of the storage battery is connected to the internal wiring of the equipment. A sealed protective shell is fixedly installed on the bottom of one of the load-bearing support plates, and the energy storage battery is placed inside the sealed protective shell.

[0010] Preferably, an annular frame is fixedly mounted on the outer wall of each of the wire harness arc frames, a photovoltaic panel is fixedly mounted inside each of the annular frames, and the connection terminals of each of the photovoltaic panels are connected to the internal wiring of the equipment.

[0011] Preferably, an extended edge is fixedly mounted on the outer surface wall of each of the cable arc frames, and an arc-shaped friction-increasing pad is covered between the inner surface wall of each of the cable arc frames and the extended edge.

[0012] Preferably, a group of connecting studs are fixedly inserted inside the four first external plates, and each group of connecting studs is movably inserted inside a corresponding connecting stud. A group of self-tapping nuts is provided at the bottom of the four first external plates, and the number of self-tapping nuts in each group is equal to that of a group of connecting studs. Each of the self-tapping nuts is rotatably connected to the outer wall of a corresponding connecting stud.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the cable is placed in the outside world for a long time, its surface material will undergo oxidation corrosion, resulting in loose connection with the equipment. At the same time, the strong airflow at high altitude will continuously impact the cable body, forcing it to swing. The generated pulling force will directly act on the cable grafting. When the two cables are separated, their outer walls will rub against the corresponding arc-shaped friction-increasing pads in two directions. The large friction force generated will impact the connection strength of the solid rod and the impact rubber sleeve until the impact rubber sleeve body breaks. Then each solid rod will generate outward pulling force. The pulling force signal generated by each inductive threaded joint is captured by the micro tension sensor and quickly transmitted to the outside through the first information line. The force signal is introduced into the receiving electronic controller, and then the received signal is introduced into the signal transmitter by the second information line. Finally, the signal transmitter builds a virtual transmission channel with the target terminal, and the induction signal is sent out in time through the enhanced antenna. The equipment uses the large friction generated by the cable displacement to force the relevant components to break, and the components capture the tension signal generated by the component offset in real time. The signal is fed back to the target terminal in time through wireless transmission. Relevant personnel can quickly formulate and implement maintenance plans based on the location of the equipment, and can solve the problem before the cable is completely detached, so as to reduce the scope of the accident and avoid large-scale and long-term power outages caused by high-voltage lines.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0017] Please see the attached Figure 1 -Attached Figure 4As shown, the present invention provides a technical solution: an anti-loosening power cable fixing device, comprising two groups of cable arc frames 1, and the number of each group of cable arc frames 1 is two, and a first external plate 2 is welded on both sides of the outer wall of each cable arc frame 1, and every two opposite first external plates 2 form a group, and a second external plate 3 is welded on the opposite side of every two cable arc frames 1, and a micro-tension sensor 5 is provided between the opposite sides of every two second external plates 3, and each micro-tension sensor 5 is fixedly connected to a group of inductive threaded joints 6 on both sides of the rear, and the outer wall of each inductive threaded joint 6 is rotatably connected to a solid rod 4, and a group of impact rubber sleeves 26 are fixedly installed on the opposite sides of every two second external plates 3, and the number of each group is the same as that of a group of inductive threaded joints. The threaded joints 6 are equal, and one end of the outer wall of each solid rod 4 is movably inserted into the interior of a corresponding second external plate 3 and fixed to a corresponding impact rubber sleeve 26. A transverse bracket 7 is fixedly installed between the opposite sides of the two groups of first external plates 2, and a load-bearing support plate 8 is fixedly installed on the top of each transverse bracket 7. A rectangular frame 9 is fixedly installed inside a load-bearing support plate 8, and a receiving electronic controller 10 is fixedly installed inside the rectangular frame 9. A signal transmitter 13 is fixedly installed on the top of a load-bearing support plate 8, and a locking joint 16 is fixedly installed on the top of the signal transmitter 13. An enhanced antenna 17 is fixedly inserted into the interior of the locking joint 16, and the input end of the enhanced antenna 17 is fixedly connected to the output end of the signal transmitter 13.

[0018] according to Figure 1 、 Figure 2 and Figure 3 As shown, the top and bottom of the two miniature tension sensors 5 are fixedly connected to a wiring base 27, and the top of the receiving electronic controller 10 and the outer wall side of the signal transmitter 13 are respectively provided with a first wiring slot 11 and a second wiring slot 14. A group of first information lines 12 are fixedly connected to the inside of each wiring base 27, and the output end of each group of first information lines 12 is respectively connected to a corresponding first wiring slot 11, and a group of second information lines 15 are fixedly connected to the inside of the second wiring slot 14, and the output ends of a group of second information lines 15 are all connected to the wiring terminals of the receiving electronic controller 10. By presetting the above components, using multiple wiring harnesses to cooperate with each other, and constructing an independent information channel, the loosening information captured by the miniature tension sensor 5 can be transmitted to the receiving electronic controller 10 in real time, and then the signal transmitter 13 uses a wireless transmission method to promptly feed back the signal to the target terminal for relevant personnel to view and quickly formulate a maintenance plan.

[0019] according to Figure 3 and Figure 4As shown, a storage battery 18 is fixedly installed at the bottom of a load-bearing tray 8, and the terminal of the energy storage battery 18 is connected to the internal wiring of the equipment. A sealed protective shell 19 is fixedly installed at the bottom of a load-bearing tray 8, and the energy storage battery 18 is placed inside the sealed protective shell 19. By presetting the above components, the sealed protective shell 19 can completely wrap the energy storage battery 18, thereby achieving a sealing effect, preventing the entry of external rainwater and moisture, eroding and damaging the sealed protective shell 19 body, and extending the functional operation life of the equipment.

[0020] according to Figure 1 and Figure 3 As shown, an annular frame 20 is fixedly mounted on the outer wall of each wire harness arc frame 1, and a photovoltaic panel 21 is fixedly mounted inside each annular frame 20. The connection terminals of each photovoltaic panel 21 are connected to the internal wiring of the equipment. By presetting the above components, the equipment takes advantage of the sufficient light intensity at high altitude and adopts the energy supplement method of photoelectric conversion to keep the energy storage battery 18 in a state of sufficient power at all times, thereby ensuring the stable energy supply to the relevant electrical components.

[0021] according to Figure 1 and Figure 4 As shown, the outer wall of each cable arc frame 1 is fixedly installed with an extended edge 22, and the inner wall between each cable arc frame 1 and the extended edge 22 is covered with an arc-shaped friction-increasing pad 23. By presetting the above components, when the equipment is assembled, each arc-shaped friction-increasing pad 23 is in full contact with the corresponding cable wall. Since the arc-shaped friction-increasing pad 23 is consistent with the outer material of the cable, the friction strength between the cable arc frame 1 and the cable can be increased, thereby avoiding position displacement during equipment operation, which leads to detection errors.

[0022] according to Figure 1 and Figure 4 As shown, a group of connecting studs 24 are fixedly inserted into the interior of the four first external plates 2, and each group of connecting studs 24 are movably inserted into the interior of a corresponding connecting stud 24. A group of self-tapping nuts 25 are provided at the bottom of the four first external plates 2, and the number of self-tapping nuts 25 in each group is equal to that of a group of connecting studs 24. Each self-tapping nut 25 is rotatably connected to the outer wall of a corresponding connecting stud 24. By presetting the above components, the longitudinal height between each two first external plates 2 can be flexibly adjusted synchronously according to the cable diameter to reduce the limitations of equipment use.

[0023] The effect achieved by the entire mechanism is as follows: the device is placed between two cables, the grafting point of the two cables is located in the middle of the device, and the processing of the grafting point of the two cables is completed inside the frame. After the process is completed, the combined cable can be in a relatively straight state, determine the position of the equipment, use the specified tool, twist each self-tapping nut 25 in turn, and reduce the distance between each cable arc frame 1 until each arc-shaped friction pad 23 is tightly attached to the target cable, reasonably control the tightening force, assemble the energy storage battery 18 and the various lines set up in the equipment, so that each electrical component is in a powered-on state. When each impact rubber sleeve 26 is not damaged, the corresponding micro-tension sensor 5 will not be pulled by external force. When the equipment is working at high altitude, external sunlight can continuously shine on each photovoltaic panel 21. The energy generated by photoelectric conversion can continuously supplement the power lost inside the energy storage battery 18. The cable is placed in the outside world for a long time. Its surface material will undergo oxidation corrosion, resulting in loose connection with the equipment. At the same time, strong airflow at high altitude will continuously impact the cable body, forcing it to swing. The resulting pulling force will directly act on the cable grafting point. When the two cables are separated, their outer walls will rub against the corresponding arc-shaped friction-increasing pads 23 from two directions. The large friction force generated will impact the connection strength between the solid rod 4 and the impact rubber sleeve 26 until the impact rubber sleeve 26 body breaks. Then, each solid rod 4 will generate an outward pulling force. The tension signal generated by each inductive threaded joint 6 is captured by the micro tension sensor 5, and the external force signal is quickly introduced into the receiving electronic controller 10 through the first information line 12. The received signal is then introduced into the signal transmitter 13 by the second information line 15. Finally, the signal transmitter 13 constructs a virtual transmission channel with the target terminal, and the induction signal is sent out in time through the enhanced antenna 17.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
