Description

Technical Field

[0001] This application relates to the field of power communication equipment technology, and in particular to a testing and maintenance device for power communication. Background Technology

[0002] The power communication network was created to ensure the safe and stable operation of the power system. Together with the power system's relay protection and safety and stability control system and dispatch automation system, it is known as the three pillars of the safe and stable operation of the power system. It is also the foundation for grid dispatch automation, network operation marketization and management modernization. In order to ensure the stability and reliability of communication, regular testing and maintenance of communication equipment are required in the power communication system.

[0003] The connection structure of existing testing and maintenance devices is not robust enough. When testing power communication equipment, the connection between the testing device and the equipment may loosen due to vibration or external force, which may affect the accuracy of the test data or even cause the test to be interrupted, requiring reconnection and testing, which wastes time and effort. Therefore, a testing and maintenance device for power communication is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a detection and maintenance device for power communication to solve the problem of unstable connection in the prior art.

[0005] The power communication testing and maintenance device provided in this application adopts the following technical solution:

[0006] A power communication testing and maintenance device includes a device housing, a testing module installed inside the device housing, and a cover hinged to the top edge of the device housing. An electrical connection socket is installed on one outer wall of the device housing. The electrical connection socket is electrically connected to the testing module. The outer wall of the electrical connection socket is provided with multiple interfaces, and connecting wires are inserted into the inner wall of the interfaces.

[0007] The outer wall of the electrical connection socket is equipped with multiple sets of fixing components, each including a guide rail, a rotating disk, and movable columns. Multiple guide rails are fixedly connected to the outer wall of the electrical connection socket, and sliders are slidably connected to the outer wall of the guide rails. The rotating disk is rotatably connected to the outer wall of the electrical connection socket through multiple connecting seats. Multiple arc-shaped grooves are formed on the outer wall of the rotating disk, and multiple movable columns are slidably connected to the inner wall of the multiple arc-shaped grooves. One end of each movable column is fixedly connected to the outer wall of the slider, and the other end is fixedly connected to an extension plate. Clamping blocks for holding connecting wires are fixedly connected to opposite ends of the multiple extension plates.

[0008] Preferably, the outer wall of the rotating disk has a clearance hole, which corresponds to the interface, and the end of the connecting line away from the interface passes through the clearance hole.

[0009] Preferably, the outer wall of the electrical connection socket is also equipped with a linkage locking mechanism for locking and driving multiple sets of fixing components to fix the connecting wires. The mechanism includes a worm gear and a locking rod. The locking rod is rotatably connected to the outer wall of the electrical connection socket through multiple shaft seats, and the worm gear is fixedly connected to the outer wall of the rotating disk through multiple connecting blocks.

[0010] Preferably, the locking rod includes multiple transmission rods and worm gears, with one end of each pair of worm gears fixedly connected to both ends of the transmission rods, and a knob fixedly connected to one end of the locking rod, and the multiple worm gears meshing with multiple worm wheels.

[0011] Preferably, a handle is fixedly connected to the outer wall of the box lid.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The fixed components can reliably fix the connecting wire. The clamping structure formed by the three clamping blocks can apply force evenly, avoiding damage or loosening of the connecting wire due to uneven local force, ensuring stable connection during testing, and preventing inaccurate data or test interruption.

[0014] 2. The linkage locking mechanism can realize the synchronous action of multiple sets of fixing components. By turning the knob, multiple sets of clamps can be clamped or released at the same time. When multiple devices or lines need to be connected for testing at the same time, it can greatly improve work efficiency, avoid the tedious operation of each one, and ensure that each connecting line is clamped evenly and stably.

[0015] 3. The linkage locking mechanism has a self-locking characteristic. After clamping the connecting wire, it can maintain a firm connection even if subjected to external vibration or external force pulling, without the need for additional fixing measures, simplifying the use process and improving the practicality and reliability of the device.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a detection and maintenance device for power communication. (Refer to...) Figure 1-4 A power communication testing and maintenance device includes a device housing 1, a housing cover 2, a testing module 3, and an electrical connection socket 4. The device housing 1 is made of sturdy metal material and has a certain level of protection, which can adapt to the complex environment of power communication sites. The housing cover 2 is hinged to the top edge of the device housing 1 and can be opened and closed easily. A handle 5 is fixedly connected to the housing cover 2 to facilitate carrying and moving the entire device.

[0023] The detection module 3 is installed inside the device housing 1. It is the core component for realizing the power communication detection function. Different types of detection modules can be selected according to specific detection needs, such as signal detection modules, fault diagnosis modules, etc. The electrical connection socket 4 is installed on one side of the outer wall of the device housing 1 and is electrically connected to the detection module 3 through internal wiring. It is used to connect external detection equipment or the power communication equipment under test.

[0024] The outer wall of the electrical connection socket 4 is provided with multiple interfaces 6. These interfaces 6 adopt the standard power communication interface type and can be adapted to various types of connection cables 7. Multiple sets of fixing components are also installed on the outer wall of the electrical connection socket 4 to fix the connection cables 7 and prevent them from loosening or falling off during the testing process.

[0025] Multiple guide rails 17 are arranged in an equally spaced circular array and fixedly connected to the outer wall around the interface 6 on the electrical connection socket 4. The cross-sectional shape of the guide rails 17 can be T-shaped or dovetail-shaped, etc. The slider 18 that cooperates with them can slide freely on the guide rails 17. The design of the slider 18 and the guide rails 17 enables the slider 18 to move stably on the guide rails 17, while restricting the displacement of the slider 18 in other directions, thus ensuring the stability and reliability of the entire fixed assembly.

[0026] The rotating disk 9 is rotatably connected to the outer wall of the electrical connection socket 4 via multiple connecting seats 8. The inner wall of the connecting seat 8 can adopt a ball bearing structure to allow the rotating disk 9 to rotate flexibly. The outer wall of the rotating disk 9 is provided with multiple arc-shaped grooves 10. The length, curvature, and inward inclination of the arc-shaped grooves 10 are designed according to actual needs. The movable column 11 is slidably connected to the inner wall of the arc-shaped groove 10. One end of the movable column 11 is fixedly connected to the slider 18, and the other end is fixedly connected to the extension plate 12. The arc-shaped groove 10 is designed to cooperate with the movement of the movable column 11. When the rotating disk 9 rotates, the movable column 11 can slide along the arc-shaped trajectory in the arc-shaped groove 10. There are three extension plates 12. The opposite ends of the three extension plates 12 are fixedly connected to clamping blocks 13. The clamping blocks 13 are made of elastic materials, such as rubber or silicone. The three clamping blocks 13 form a triangular clamping structure, which can better clamp the connecting wire 7 without damaging the connecting wire 7.

[0027] When the rotating disk 9 rotates, the movable column 11 is slidably connected to the arc groove 10 on the rotating disk 9, and one end of the movable column 11 is fixedly connected to the slider 18. Therefore, the rotation of the rotating disk 9 will cause the movable column 11 to slide in the arc groove 10. As the movable column 11 slides in the arc groove 10, the slider 18 will move linearly on the guide rail 17 accordingly. Because the extension plate 12 is fixedly connected to the movable column 11, the linear movement of the slider 18 will be transmitted to the extension plate 12 through the movable column 11, thereby driving the clamping block 13 to move. When the three clamping blocks 13 move towards the center at the same time, they will gradually approach and clamp the connecting line 7 placed in the middle. When the three clamping blocks 13 move away from the center, they will release the clamping of the connecting line 7.

[0028] The outer wall of the rotating disk 9 is provided with a clearance hole 14, which corresponds to the interface 6. Its size and shape can ensure that the end of the connecting wire 7 away from the interface 6 can pass smoothly through the clearance hole 14, which is convenient for connecting to external equipment.

[0029] In order to achieve synchronous locking and driving of multiple fixed components, a linkage locking mechanism is also installed on the outer wall of the electrical connection socket 4. The linkage locking mechanism includes a worm gear 15 and a locking rod 20. The worm gear 15 is fixedly connected to the outer wall of the rotating disk 9 through multiple connecting blocks 16, and the locking rod 20 is rotatably connected to the outer wall of the electrical connection socket 4 through multiple bearings 19.

[0030] The locking rod 20 includes multiple transmission rods 201 and worm gears 202. The opposite ends of every two worm gears 202 are fixedly connected to the two ends of the transmission rods 201 to form a whole locking rod 20. A knob 203 is fixedly connected to one end of the locking rod 20 to facilitate manual rotation of the locking rod 20 by the operator. Multiple worm gears 202 mesh with multiple worm wheels 15. When the knob 203 is rotated, the locking rod 20 rotates around the shaft seat 19, and the worm gears 202 drive the worm wheels 15 to rotate, thereby causing the rotating disk 9 to rotate. Through the linkage of components such as the movable column 11 and the slider 18, the clamping or loosening action of multiple sets of three clamping blocks 13 on the connecting line 7 is realized.

[0031] The meshing of the worm 202 and the worm wheel 15 has a unique self-locking characteristic. Due to the small helix angle of the worm 202, when the worm wheel 15 drives the worm 202 to rotate in the opposite direction, a large frictional resistance is generated, making it difficult for the worm wheel 15 to easily drive the worm 202 to rotate. When the locking rod 20 is rotated by the knob 203, the worm 202 drives the worm wheel 15 to rotate, thereby clamping the connecting wire 7. Even if the connecting wire 7 is subjected to external vibration or external force pulling, the worm wheel 15 will not easily rotate in the opposite direction, thus ensuring the continuous clamping state of the clamping block 13 on the connecting wire 7 and realizing the self-locking function. This self-locking characteristic effectively prevents problems such as inaccurate test data or test interruption caused by the loosening of the connecting wire 7 during the test process.

[0032] The implementation principle of the power communication testing and maintenance device in this application embodiment is as follows: When in use, open the box cover 2, connect the testing module 3 to the electrical connection socket 4, and connect the power communication equipment to be tested to the interface 6 of the electrical connection socket 4 through the connecting cable 7. Then, place the connecting cable 7 in the clamping area formed by the three clamping blocks 13, rotate the knob 203, and drive the fixing component to move through the linkage locking mechanism, so that the three clamping blocks 13 clamp the connecting cable 7 to prevent it from loosening. After the test is completed, rotate the knob 203 in the opposite direction to release the clamping blocks 13, unplug the connecting cable 7, and close the box cover 2.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
