[0044] Embodiment 1

[0045] Figure 1 A schematic diagram of the structure of a cable calibration tool provided in the first embodiment of the present invention is shown in FIG. Figure 1 and Figure 2 As shown, the cable calibration tool includes a first detection mechanism 1, a connecting line 2 and a second detection mechanism 3.

[0046] The first detection mechanism 1 includes a handheld portion 11, a detection probe 12 and a first insulating sleeve 13. The detection probe 12 is made of a conductive material. In some embodiments, the detection probe 12 is made of copper. In other embodiments, the detection probe 12 may also be made of other conductive materials, which are not specifically limited here. Therefore, when calibrating the cable, since the end of the cable usually has a terminal, the detection probe 12 only needs to be inserted into the terminal, and the detection probe 12 is electrically connected to the cable, which is convenient to connect.

[0047] The detection probe 12 is fixedly connected to the handheld portion 11, and the handheld portion 11 is specifically cylindrical, so that the staff can hold it comfortably. It can be understood that in other embodiments, the handheld portion 11 can also be other shapes, which are not specifically limited here, but are just examples. The first insulating sleeve 13 wraps the handheld portion 11, and the first insulating sleeve 13 is made of insulating material, so that the staff is not easy to get an electric shock when holding the handheld portion 11, which improves safety.

[0048] The second detection mechanism 3 includes a detection clamp 31 and a second insulating sleeve 32. The detection clamp 31 includes a clamping portion 312 and a pressing portion 311. The clamping portion 312 includes a clamping opening. The pressing portion 311 is used to be pressed to open or close the clamping opening of the clamping portion 312. Therefore, when connecting with the grounding component, only the pressing portion 311 needs to be operated to make the clamping portion 312 clamp the grounding component through the clamping opening, and the connection is more convenient.

[0049] The second insulating sleeve 32 wraps the pressing portion 311, and the first insulating sleeve 13 is made of insulating material, so that the worker is not easily electrocuted when pressing the pressing portion 311, thereby improving safety. The clamping portion 312 is made of a conductive material, preferably, the clamping portion 312 is made of copper, and in other embodiments, the clamping portion 312 may also be made of other conductive materials.

[0050] One end of the connecting wire 2 is electrically connected to the detection probe 12. Specifically, the connecting wire 2 is a copper wire, so that the connecting wire 2 has good insulation and low resistance, ensuring accurate test results and safety of testers. In some embodiments, the connecting wire 2 includes an insulating layer 21 and a conductor 22, the conductor 22 is located inside the insulating layer 21, and the conductor 22 inside the connecting wire 2 is welded and fixed to the detection probe 12. At the same time, the welding point of the two can be located inside the handheld part 11, so that the connection is relatively stable and not easily loosened by external force. The other end of the connecting wire 2 is electrically connected to the clamping part 312. Specifically, the conductor 22 inside the connecting wire 2 is welded and fixed to the clamping part 312. In some embodiments, the detection clip 31 is specifically an alligator clip, and the alligator clip includes an insulating handle. At this time, the pressing part 311 and the clamping part 312 are different parts on the alligator clip. The pressing part 311 is also made of conductive material, and the conductor 22 inside the connecting wire 2 can be welded and fixed to one end of the pressing part 311 away from the clamping part 312.

[0051] The above scheme, by setting the first detection mechanism 1, the connecting line 2 and the second detection mechanism 3, the first detection mechanism 1 has a handheld part 11, a detection probe 12 and a first insulating sleeve 13, the second detection mechanism 3 includes a detection clamp 31 and a second insulating sleeve 32, the detection clamp 31 includes a clamping part 312 and a pressing part 311, the clamping part 312 includes a clamping mouth, and the pressing part 311 is used to be pressed to open or close the clamping mouth of the clamping part 312. Therefore, when calibrating the cable, it is only necessary to insert the detection probe 12 into the cable terminal, and then clamp the grounding part with the clamping part 312 of the detection clamp 31, so that the end of the cable can be connected to the grounding part. Compared with the related art that needs to remove the insulating layer 21 at both ends of the wire, so that the conductors 22 at both ends of the wire are connected to the cable terminal and the grounding part respectively, this scheme can conveniently and reliably connect the cable and the grounding part, can effectively shorten the cable calibration time, and improve the accuracy of cable calibration. At the same time, by setting the first insulating sleeve 13 to wrap the handheld part 11 and setting the second insulating sleeve 32 to wrap the pressing part 311, the safety of cable calibration is effectively improved. In addition, the cable calibration tool can also be used as a discharge tool for ordinary equipment. Therefore, the problems of complex calibration environment and long calibration time are solved, and the cable calibration in the ship commissioning process is completed efficiently, safely and economically.

[0052] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the first insulating sleeve 13 also wraps the end of the detection probe 12 close to the hand-held part 11, thereby not only fixing the detection probe 12, but also eliminating the potential safety hazard caused by the excessive length of the detection probe 12.

[0053] In some embodiments, the length of the portion of the detection probe 12 not wrapped by the first insulating sleeve 13 is any value between 0.8 cm and 2 cm. Preferably, the length of the portion of the detection probe 12 not wrapped by the first insulating sleeve 13 is 1 cm. Preferably, the length of the portion of the detection probe 12 not wrapped by the first insulating sleeve 13 is 1.5 cm. Preferably, the length of the portion of the detection probe 12 not wrapped by the first insulating sleeve 13 is 2 cm. Thus, the detection probe 12 can be inserted into the terminal at the end of the cable, and less exposed portion not wrapped by the first insulating sleeve 13 after insertion, thereby preventing staff from contacting the portion of the detection probe 12 not wrapped by the first insulating sleeve 13, eliminating the potential safety hazard caused by the excessive length of the detection probe 12.

[0054] In some embodiments, Figure 1 and Figure 3 As shown, the second insulating sleeve 32 at least partially wraps the clamping portion 312, thereby preventing the conductive portion of the clamping portion 312 from being exposed and causing safety hazards.

[0055] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the diameter of the detection probe 12 is any value between 0.9 mm and 1.1 mm. Preferably, the diameter of the detection probe 12 is 1 mm. Preferably, the diameter of the detection probe 12 is 0.95 mm. Preferably, the diameter of the detection probe 12 is 1.05 mm. Thus, the detection probe 12 is easy to insert into the terminal at the end of the cable.

[0056] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the first insulating sleeve 13 is made of a heat shrink tube, which can shrink evenly after heating, closely fit the surface of the protected object, and form a dense insulating layer 21. Since the hand-held part 11 and the detection probe 12 are of different sizes, the first insulating sleeve 13 is made of a heat shrink tube, and the first insulating sleeve 13 can better fit the hand-held part 11 and the detection probe 12. At the same time, the heat shrink tube has excellent insulation, high temperature resistance, chemical corrosion resistance and aging resistance.

[0057] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the second insulating sleeve 32 is made of a heat shrink tube. Since the pressing portion 311 has an irregular shape, the second insulating sleeve 32 is made of a heat shrink tube, so that the second insulating sleeve 32 can better fit the pressing portion 311.

[0058] In an optional embodiment of the present invention, the length of the handheld portion 11 is any value between 7 cm and 9 cm. Preferably, the length of the handheld portion 11 is 8 cm. Preferably, the length of the handheld portion 11 is 7.5 cm. Preferably, the length of the handheld portion 11 is 8.5 cm. Thus, the user has a better experience when holding the handheld portion 11.

[0059] In an optional embodiment of the present invention, the diameter of the handheld portion 11 is any value between 0.8 cm and 1.2 cm. Preferably, the diameter of the handheld portion 11 is 1 cm. Preferably, the diameter of the handheld portion 11 is 0.9 cm. Preferably, the diameter of the handheld portion 11 is 1.1 cm. A handheld portion 11 that is too small or too large is not conducive to the staff holding it. By setting the diameter of the handheld portion 11 to any value between 0.8 cm and 1.2 cm, the staff has a better experience when holding it and it is easy to operate.

[0060] In an optional embodiment of the present invention, Figure 1 and Figure 2As shown, the length of the connecting wire 2 is any value between 15cm and 25cm. Preferably, the length of the connecting wire 2 is 20cm. Preferably, the length of the connecting wire 2 is 15cm. Preferably, the length of the connecting wire 2 is 22cm. Preferably, the length of the connecting wire 2 is 24cm. When the connecting wire 2 is too long, it is easy to cause problems such as signal attenuation, noise interference, and cost increase. When the connecting wire 2 is too short, it may be inconvenient to connect the grounding component and the terminal. By making the length of the connecting wire 2 any value between 15cm and 25cm, it is possible to control the cost and ensure the connection quality while facilitating the connection.

[0061] Embodiment 2

[0062] Embodiment 2 of the present invention provides a ship cable calibration system, which includes a ship body, a multimeter and a cable calibration tool according to any embodiment of the present invention, such as Figure 4 As shown, the ship body is provided with a cable to be tested and a grounding component 30. The cable to be tested refers to a cable that needs to be calibrated. The cable to be tested is usually buried inside the ship body and is relatively long. Therefore, during debugging, the cable to be tested needs to be calibrated to see whether the cable to be tested is normal without any disconnection faults. The grounding component 30 is a grounding component on the ship body. In some embodiments, the grounding component 30 includes a grounding bolt, a copper bar, an equipment housing, a hull component, etc.

[0063] The cable to be tested includes a first end and a second end opposite to each other, and the first end of the cable to be tested is provided with a terminal 20. The detection probe 12 of the cable calibration tool is inserted into the terminal 20, and the clamping portion 312 of the cable calibration tool clamps the grounding component 30, thereby achieving the connection between the terminal 20 and the grounding component 30. The multimeter is electrically connected to the second end of the cable to be tested, so that the multimeter can detect whether the cable to be tested is normal, so as to achieve the calibration of the cable to be tested.

[0064] The above scheme, through the cable calibration tool and the multimeter, only needs to insert the detection probe 12 of the cable calibration tool into the terminal 20, and the clamping part 312 of the cable calibration tool clamps the grounding component 30, so as to realize the connection between the terminal 20 and the grounding component 30. Then connect the multimeter to the other end of the cable to be tested away from the cable calibration tool, and the cable can be calibrated according to the detection value of the multimeter, so that the cable can be connected to the grounding component 30 conveniently and reliably, effectively shortening the cable calibration time, thereby effectively shortening the debugging hours, and in addition, it can also improve the safety and accuracy of cable calibration. After testing, the accuracy of cable calibration is improved by 20%, and the safety of cable calibration is improved by 30%.

[0065] Embodiment 3

[0066] Embodiment 3 of the present invention provides a ship cable calibration method, which is used in the ship cable calibration system described in any embodiment of the present invention, such as Figure 5 As shown, the ship cable calibration method includes:

[0067] S110, inserting a detection probe of the cable calibration tool into the wiring terminal of the first end of the cable to be tested on the ship body.

[0068] Since the detection probe is made of conductive material, when the detection probe is inserted into the wiring terminal, the detection probe is electrically connected to the cable to be tested.

[0069] S120, pressing the pressing portion of the cable calibration tool so that the clamping portion of the cable calibration tool clamps the grounding component on the ship body.

[0070] Among them, since the clamping part is made of conductive material, when the clamping part clamps the grounding component, the clamping part is grounded, and the clamping part is electrically connected to the detection probe through the connecting wire, so the cable to be tested is grounded at this time.

[0071] S130, electrically connecting the multimeter to the second end of the cable to be tested.

[0072] The cable to be tested is usually buried inside the ship, and the multimeter is connected to the second end of the cable to be tested. Since the first end of the cable to be tested is grounded, the multimeter can calibrate the cable at this time.

[0073] S140, obtaining resistance information detected by the multimeter.

[0074] The resistance value information refers to the resistance value detected by the multimeter when the second end of the cable to be tested is connected.

[0075] S150. Determine cable calibration information based on the resistance information.

[0076] The cable calibration information is information reflecting whether the cable to be tested is normal. The resistance of the cable to be tested will be different when it is faulty and normal. Therefore, by obtaining the resistance information, the cable calibration information can be determined based on the resistance information.

[0077] The above scheme is to insert the detection probe of the cable calibration tool into the terminal block at the first end of the cable to be tested on the ship body; press the pressing part of the cable calibration tool so that the clamping part of the cable calibration tool clamps the grounding component on the ship body; then electrically connect the multimeter to the second end of the cable to be tested; obtain the resistance information detected by the multimeter; and finally determine the cable calibration information based on the resistance information. In this way, the cable can be connected to the grounding component conveniently and reliably, effectively shortening the cable calibration time, thereby effectively shortening the debugging hours. In addition, it can also improve the safety and accuracy of cable calibration. After testing, the accuracy of cable calibration is improved by 20%, and the safety of cable calibration is improved by 30%.

[0078] In an optional embodiment of the present invention, determining the cable calibration information based on the resistance information includes: when the resistance information is 0, determining that the cable calibration information indicates that the cable to be tested is normal.

[0079] Among them, when the cable to be tested is normal and not broken, since the cable to be tested has been grounded through the cable calibration tooling at this time, the loop resistance should be 0. Therefore, when the resistance information detected by the multimeter is 0, it means that the cable calibration information shows that the cable to be tested is normal, and the calibration of the cable to be tested is achieved.

[0080] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0081] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
