[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, the embodiment of the utility model proposes a fault cable locating device, which is installed on the cable body 1 and is characterized in that it includes:

[0025] Two clamping plates 2, the ends of the two clamping plates 2 are hinged and mutually buckled on the cable body 1;

[0026] A monitoring assembly, including a sensor 7 and a positioner 8 disposed on one of the clamping plates 2, so that a monitoring channel is formed between the two clamping plates 2; and

[0027] The fixing assembly includes two extrusion plates 3 slidably arranged on the peripheral side of the clamp plate 2 and extrusion pieces arranged at both ends of the clamp plate 2. When the extrusion plates 3 move axially along the monitoring channel, the extrusion pieces are pressed to move radially along the monitoring channel and abut against or separate from the cable body 1.

[0028] In the embodiment of the utility model, under the action of the two clamps 2, the two clamps 2 can be installed on the cable body 1 in a snap-fitting manner, synchronously with the laying of the cable 1, to form one of the monitoring points in the axial direction of the cable, and an elastic card block 6 is provided at the end of one of the clamps 2, and the other clamp 2 is provided with a card slot 10 corresponding to the elastic card block 6. When the two clamps 2 are snapped together, the elastic card block 6 is snapped into the card slot 10. After the two clamps 2 are snapped together, the elastic card block 6 on one of the clamps 2 is automatically snapped into the card slot 10 of the other clamp 2, ensuring that the two clamps 2 are in a ring state on the cable body 1. In the process of laying the cable, a combination of several two clamps 2 is installed at different points in the axial direction of the cable body 1, and multi-point monitoring is implemented on the cable body 1. When the cable is running, with the cooperation of the monitoring component, the sensor 7 and the locator 8 are installed inside one of the clamps 2, so that a monitoring channel for installing and monitoring the cable is formed between the two clamps 2. In the selection of the sensor 7 and the locator 8, the sensor 7 adopts the Lake Shore Hall sensor. When the current flows, the conductor is placed in the magnetic field, and a voltage is generated on the conductor sheet. The output voltage proportional to the magnetic flux density is provided for monitoring. The locator 8 is a GPS positioning system, which is electrically connected to each other and communicated with the external control system. With the cooperation of the batch monitoring components and the two clamps 2 adapted thereto, when a fault occurs at a certain stage of the cable body 1, the first monitoring component after the fault point senses the change in current, and the sensor 7 at this position transmits a signal to the locator 8, so that the locator 8 transmits the position where the cable fault occurs to the control center, so that the staff can quickly know the position where the problem occurs in the cable body 1, and accurately locate the fault point, saving time and improving work efficiency to a certain extent.

[0029] Secondly, since the installation of the clamp 2 is carried out along with the laying of the cable body 1, in order to increase the risk that the clamp 2 will not be affected by the swaying and displacement caused by the subsequent installation of the cable body 1 after installation, with the cooperation of the extrusion plate 3 and the extrusion piece in the fixing assembly, when the two clamps 2 are buckled on the cable body 1, the extrusion piece is subjected to the pressure of the extrusion plate 3 to move radially along the monitoring channel and abut against the cable body 1, which can improve the stability of the two clamps 2 installed on the cable body 1, making it less likely to shift during the laying of the cable body 1, thereby ensuring stability.

[0030] Based on the above scheme, Figure 2 and Figure 4 As shown, the extrusion piece includes a fixing plate 4 arranged at the end of the clamping plate 2 and a plurality of spring pieces 5 arranged on the fixing plate 4, the spring piece 5 is provided with an extrusion portion 11, and the extrusion plate 3 abuts against the extrusion portion 11 so that the end of the spring piece 5 protrudes out of the fixing plate 4 and abuts against the cable body 1. Specifically, when the two clamping plates 2 are fixed on the cable 1 by the cooperation of the extrusion piece and the extrusion plate 3, the movable extrusion plate 3 is used to make one end of the extrusion plate 3 gradually protrude from the end of the clamping plate 2 and gradually abut against the extrusion portion 11 of the spring piece 5. The inclined surface of the extrusion portion 11 has a certain angle with respect to the top surface of the spring piece 5, so after the extrusion portion 11 is subjected to the extrusion force of the extrusion plate 3, the spring piece 5 is deformed inwardly and gradually abuts against the cable body 1 to complete the fixation. By controlling the different deformation amounts of the spring piece 5 at different positions of the movable extrusion plate 3 on the clamping plate 2, the two clamping plates 2 can be fixed on the cable body 1 of different diameters. For the convenience of operation, the two clamping plates 2 are provided with fixing components of the same structure.

[0031] Specifically, the fixing plate 4 is an arc-shaped structure with the monitoring channel as the axis, and a plurality of spring pieces 5 are arranged at intervals along the circumference of the fixing plate 4, so that the distribution direction of the plurality of spring pieces 5 is arranged along the surface of the cable body 1, which is closer to the shape of the cable body 1, and ensures the stability of the fixation. In addition, a friction layer 12 is provided at the end of the spring piece 5, which can increase the friction between the end of the spring piece 5 and the cable body 1, and further improve the stability.

[0032] Specifically, Figure 5 As shown, both extrusion plates 3 are provided with threaded blocks 13, and the clamping plate 2 is provided with a bidirectional screw 14 for rotation. The two threaded blocks 13 are respectively connected to the two ends of the bidirectional screw 14. In order to avoid the position change of the extrusion plate 3 after the extrusion plate 3 is adjusted, the bidirectional screw 14 is rotated when the extrusion plate 3 is adjusted, so that the two extrusion plates 3 in one clamping plate 2 are synchronously extended from the two ends of the clamping plate 2. After the adjustment is stopped, the bidirectional screw 14 can realize self-locking, thereby ensuring the stability of the extrusion plate 3 after adjustment. The middle part of the bidirectional screw 14 is provided with an adjustment knob 9, which is convenient for manual adjustment of the bidirectional screw 14.

[0033] In summary, the present invention firstly fixes and buckles the two clamps 2 on the cable body 1 through the elastic clamp block 6 and the clamping groove 10, and then rotates the adjusting knob 9 to make the two extrusion plates 3 in one clamp 2 extend out of the two ends of the clamp 2 synchronously, so that the extrusion part 11 is subjected to the extrusion force of the extrusion plate 3, so that the spring piece 5 is deformed inward, and gradually abuts against the cable body 1 to complete the fixation, and then follows the above operation to install several combinations of two clamps 2 to different points of the cable body 1, and connect the sensor 7 and the locator 8 to electricity in turn, and monitor the current in the monitoring channel through the sensor 7. When a fault occurs and causes the current in the monitoring channel to change, the signal sent by the sensor 7 is received by the external control system connected to the sensor 7, and the specific fault location is informed by the locator 8, so that the fault point can be accurately located with higher efficiency.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
