[0002] Lightning protection detection is an important safety guarantee measure, aiming to evaluate the lightning protection capabilities of buildings, equipment, facilities, etc., so as to reduce the losses caused by lightning disasters. During the lightning protection detection process, detection cables are usually used to transmit detection signals and data.

[0003] However, in traditional lightning protection detection, there are many defects in the winding method of detection cables. Due to the lack of an effective winding device, the detection cables are often tangled together randomly, which not only affects the efficiency of the detection work, but also easily causes damage to the cables.

[0004] In addition, the detection cables cannot be wound separately by category, making it difficult to quickly and accurately find the specific cables when needed, increasing the complexity and time cost of the detection work.

[0005] More seriously, in some complex detection environments, the detection cables are easily wrapped with impurities such as soil. These impurities will not only affect the performance and service life of the cables, but may also interfere with the transmission of detection signals, resulting in inaccurate detection results.

[0031] The following further describes the present utility model in detail with reference to the drawings.

[0032] Combined with the attachedFigure 1 To the attached Figure 5 , a multifunctional lightning protection detection auxiliary device, including a housing 1. Inside the housing 1, a partition 2 is fixedly arranged to divide the internal space of the housing 1 into multiple cable winding chambers 3. Inside each of the cable winding chambers 3, a winding roller 4 is rotatably connected. A torsion spring 5 is connected between the bottom of the winding roller 4 and the bottom surface of the housing 1. A limiting mechanism is arranged in a matching manner between the upper end of the winding roller 4 and the top surface of the housing 1. The inside of the winding roller 4 is hollow and a detection cable 6 is threaded through it. At the upper end of each of the cable winding chambers 3, a conductive slip ring 7 is fixedly arranged. The upper end of the detection cable 6 is connected to the conductive slip ring 7 and the lower end passes out from the side of the winding roller 4 and is wound around the winding roller 4. On the front of each of the cable winding chambers 3, a through hole 8 for the detection cable 6 to pass through is provided, and a cable cleaning mechanism is fixedly arranged outside the through hole 8.

[0033] Refer to the attached Figure 4 , the limiting mechanism includes a limiting chuck 9 fixedly arranged at the upper end of the winding roller 4, and further includes a limiting pin 10 inserted into the upper end of the housing 1. The limiting pin 10 is clamped with the limiting chuck 9 in a matching manner. The limiting chuck 9 is disc-shaped and a number of semi-circular notches 11 are arranged along its circumferential direction. The limiting pin 10 is clamped with the semi-circular notches 11 in a matching manner.

[0034] Refer to the attached Figure 1 , the cable cleaning mechanism includes an annular sleeve 12 fixedly arranged on the front of the cable winding chamber 3. A number of evenly distributed bristles 13 are fixedly arranged on the inner wall of the annular sleeve 12. The detection cable 6 passes through the annular sleeve 12. The bristles 13 are made of rubber material.

[0035] In this embodiment, a cable connector 14 is connected to the upper end of the conductive slip ring 7. The cable connector 14 is connected to an external lightning protection detection instrument, and a detection probe is connected to the distal end of the detection cable 6.

[0036] The working principle of the present utility model is as follows: This multifunctional lightning protection detection auxiliary device mainly relies on the elastic potential energy of the torsion spring 5, the rotation of the winding roller 4, and the signal transmission of the conductive slip ring 7 to realize the retraction and extension of the detection cable and stable detection. The torsion spring 5 stores elastic potential energy when the detection cable 6 is pulled out. When the external force disappears, the torsion spring 5 releases the potential energy to drive the winding roller 4 to automatically wind up the cable. The hollow design of the winding roller 4 facilitates the threading and winding of the cable. The conductive slip ring 7 ensures the stable transmission of the detection signal during the winding and rotation of the detection cable, without being affected by cable entanglement.

[0037] The specific use process of the present utility model is as follows:

[0038] 1. Preparation work: Connect the external lightning protection detection instrument to the cable connector 14 to ensure a firm connection. Install the detection probe at the distal end of the detection cable 6 in place.

[0039] 2. Select the cable: According to the detection requirements, determine the cable winding chamber 3 where the detection cable 6 to be used is located.

[0040] 3. Pull out the cable: Pull out the corresponding limit pin 10 to release the restriction on the winding roller 4. Manually pull out the required length of the detection cable 6 from the through hole 8. At this time, the coil spring 5 is stretched to store elastic potential energy.

[0041] 4. Conduct the detection: Place the probe of the pulled-out detection cable 6 at the position to be detected. At this time, the limit pin 10 can be inserted back to fix the position of the winding roller 4, and start the lightning protection detection work.

[0042] 5. Retract the cable: After the detection is completed, remove the detection probe, pull out the limit pin 10, and no longer apply tension to the detection cable 6. The elastic potential energy of the coil spring 5 is released, driving the winding roller 4 to rotate automatically, and winding the detection cable 6 around and back onto the winding roller 4.

[0043] 6. Cable cleaning: During the process of retracting the detection cable 6, when passing through the annular sleeve 12, the brush bristles 13 will automatically clean the impurities such as soil wrapped on the cable surface.

[0044] 7. Limit and fixation: When the detection cable 6 is completely retracted, insert the limit pin 10 to engage with the semi-circular notch 11 of the limit chuck 9 to fix the winding roller 4 and prevent the cable from being accidentally released.

[0045] The above describes the present utility model and its implementation manners. This description is not restrictive.
