During the lightning protection testing process, testing cables are usually used to transmit testing signals and data.

[0003] In the prior art, Chinese utility model patent with publication number CN223133752U discloses a multi-functional lightning protection detection auxiliary device. Although this prior art has achieved cable classification, winding, and surface cleaning to a certain extent, in actual use, the prior art uses a coil spring as the winding power source. However, the coil spring is in a state of repeated tension for a long time, which is prone to fatigue fracture or elastic decay, resulting in failure of the winding function and affecting the overall service life of the device. Moreover, the winding speed of the coil spring is uncontrollable, and the cable is prone to swinging, tangling, or friction damage with the wall of the through hole when it is retracted. In addition, the fixed bristles can only remove loose dirt on the surface of the cable, and the effect of removing dirt that is sticky or has dried is poor. In view of this, we propose a multi-functional lightning protection detection auxiliary device to solve the above problems. Utility Model Content

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A multifunctional lightning protection detection auxiliary device includes a housing 1. Inside the housing 1 are three winding rollers 2, arranged side-by-side and spaced apart along the width of the housing 1. Each winding roller 2 corresponds to an independent drive and transmission assembly. Since the three winding rollers 2 have the same structure and connection method, the following description focuses on one winding roller 2. Support rods 3 are fixedly connected to both the upper and lower ends of the winding roller 2. The winding roller 2 is rotatably connected to the bottom wall of the housing 1 via the lower support rod 3. An installation groove 4 is provided inside the upper support rod 3. A one-way bearing 5 is fixedly installed inside the installation groove 4. A drive shaft 6 is fixedly sleeved inside the one-way bearing 5. The upper end of the drive shaft 6 rotatably extends through the interior of the housing 1. A drive disc 7 is provided on the upper side of the drive shaft 6. A first rotating ring 8 is rotatably sleeved inside the front plate of the housing 1. A second rotating ring 9 is fixedly installed at the front end of the first rotating ring 8. Several bristles 10 are fixedly connected to the inner ring surface of the second rotating ring 9. A transmission mechanism is provided inside the housing 1.

[0030] The box 1 is also equipped with a partition (not shown in the figure) inside, which is mainly used to separate the three winding rollers 2, thereby forming different chambers and achieving the purpose of classified winding.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a ratchet mechanism 22 is provided on the outside of the upper support rod 3, and a detection cable 24 is provided inside the second rotating ring 9, which extends from the inside of the housing 1 and is wound around the outside of the take-up roller 2. A cable connector 23 extending into the inside of the housing 1 is provided on the top of the housing 1.

[0032] In addition, by using the one-way bearing 5, when the detection cable 24 is pulled outward, the winding roller 2, the support rod 3 and the one-way bearing 5 can be driven to move, but the drive shaft 6 cannot be driven to rotate. However, when the cable needs to be wound up, the drive shaft 6 is rotated in the opposite direction. At this time, the one-way bearing 5 can be used to drive the support rod 3 to rotate, thereby realizing the winding of the cable.

[0033] The ratchet mechanism 22 includes a ratchet body, a ratchet tooth body, a shaft, a torsion spring, and a knob. By fixing the ratchet tooth body to the outside of the upper support rod 3, the take-up roller 2 can only rotate when pulling the cable wound on the outside, and cannot rotate in reverse, thereby avoiding the accidental retraction of the cable. When it is necessary to retract the cable, the ratchet tooth body and the ratchet body can be separated by turning the knob. Since this is a conventional technical means in the field, it will not be described in detail in this article.

[0034] It should be noted that in this device, the ratchet mechanism 22 and the one-way bearing 5 perform different functions. Specifically, when the cable is pulled out to the required length, the ratchet mechanism 22 is used to lock the take-up roller 2 to prevent it from accidentally reversing under external force or vibration, which would cause the cable to come loose. It is a static locking mechanism. The one-way bearing 5, on the other hand, is a power transmission element between the drive shaft 6 and the support rod 3 during the active winding action. Its function is to ensure that the take-up roller 2 can rotate freely when the cable is unloaded (the drive shaft 6 does not rotate), and to transmit torque only when the cable is wound up (the drive shaft 6 rotates in the forward direction). The two do not overlap in function, but act on the two different working conditions of locking after unloading and transmission during winding. The two work together to ensure the stability and reliability of the device operation.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the transmission mechanism includes a transmission shaft 11, which is rotatably connected to the top wall of the housing 1, and a first bevel gear 12 is fixedly sleeved on the lower end of the transmission shaft 11.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second bevel gear 13 is fixedly sleeved on one end surface of the first rotating ring 8 located inside the housing 1, and the first bevel gear 12 and the second bevel gear 13 are meshed together.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a first synchronous pulley 14 and a second synchronous pulley 15 are respectively fixedly sleeved on the outside of the transmission shaft 11 and the drive shaft 6. A synchronous belt 16 is sleeved on the outside of the first synchronous pulley 14 and the second synchronous pulley 15. The rotation of the drive shaft 6 can drive the rotation of the second synchronous pulley 15. At this time, with the cooperation of the synchronous belt 16, the rotation of the first synchronous pulley 14 can be driven. The rotation of the first synchronous pulley 14 can drive the rotation of the transmission shaft 11. The rotation of the transmission shaft 11 and the transmission of the first bevel gear 12 and the second bevel gear 13 can drive the rotation of the first rotating ring 8. The rotation of the first rotating ring 8 can drive the rotation of the second rotating ring 9, thereby causing the bristles 10 inside the second rotating ring 9 to rotate on the surface of the detection cable 24, and to roll and wipe the detection cable 24, effectively improving the efficiency of removing dirt.

[0038] The synchronous belt 16 engages with the tooth grooves on the surfaces of the first synchronous pulley 14 and the second synchronous pulley 15 through its surface teeth, thereby effectively ensuring the stability of the transmission between the synchronous belt 16 and the first synchronous pulley 14 and the second synchronous pulley 15.

[0039] Example 2

[0040] The multifunctional lightning protection detection auxiliary device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a sliding groove 17 is provided inside the drive shaft 6. A rotating rod 18 is slidably connected inside the sliding groove 17. The rotating rod 18 slides through the upper end of the drive shaft 6, and the upper end of the rotating rod 18 is fixedly connected to the drive disk 7. The rotating rod 18 can be rotated by the operator rotating the drive disk 7, and the rotation of the rotating rod 18 can drive the rotation of the drive shaft 6.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a first toothed ring 20 is fixedly connected to the lower surface of the drive disk 7, and a second toothed ring 21 is fixedly connected to the upper surface of the housing 1. The diameter of the second toothed ring 21 is smaller than the diameter of the first toothed ring 20, and the first toothed ring 20 and the second toothed ring 21 mesh. When the first toothed ring 20 and the second toothed ring 21 mesh, the drive disk 7 cannot rotate because the second toothed ring 21 is fixed to the top of the housing 1, thus ensuring the stability of the drive shaft 6. When the drive disk 7 is pulled upward to separate the first toothed ring 20 and the second toothed ring 21, the drive disk 7 can then be rotated.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 As shown, a return spring 19 is fixedly connected between the lower end of the rotating rod 18 and the top wall of the sliding groove 17. The return spring 19 is movably sleeved on the outside of the rotating rod 18. The setting of the return spring 19 further ensures the stability of the drive disk 7 and the stability of the engagement of the first toothed ring 20 and the second toothed ring 21.

[0043] When the operator needs to rewind a certain test cable 24, they only need to operate the drive disc 7 corresponding to that cable. By pulling the drive disc 7 upward, its first toothed ring 20 is separated from the second toothed ring 21 on the housing 1. Then, the drive disc 7 is rotated in the forward direction. The drive disc 7 drives the drive shaft 6 to rotate in the inner ring of the one-way bearing 5 through the rotating rod 18. Due to the characteristics of the one-way bearing 5 (the inner ring can drive the outer ring when it rotates actively), the drive shaft 6 drives the support rod 3 and the winding roller 2 to rotate synchronously through the one-way bearing 5, thereby realizing the winding of the test cable 24.

[0044] As the drive shaft 6 rotates, the second synchronous wheel 15, which is fixedly sleeved outside the drive shaft 6, rotates accordingly. It drives the first synchronous wheel 14 to rotate via the synchronous belt 16. The first synchronous wheel 14 drives the transmission shaft 11 to rotate. Then, through the meshing of the first bevel gear 12 and the second bevel gear 13, it drives the first rotating ring 8 and the second rotating ring 9 to rotate on the front side plate of the housing 1. The bristles 10 on the inner ring surface of the second rotating ring 9 rotate accordingly, and roll and wipe the surface of the detection cable 24 that is passing through its interior and being wound up. Since the drive shaft 6, transmission shaft 11, synchronous wheel and bevel gear of each winding roller 2 are set independently and do not interfere with each other, the staff can perform independent winding and cleaning operations on the three winding rollers 2 as needed.

[0045] The usage process of the multifunctional lightning protection detection auxiliary device provided by this utility model is as follows:

[0046] First, the staff manually pulls out the test cable 24 from the corresponding cable winding chamber according to the required test cable 24. At this time, since the support rod 3 on the lower side of the winding roller 2 is rotatably connected to the bottom wall of the box 1, and the one-way bearing 5 is installed inside the upper support rod 3, the winding roller 2 can rotate freely during the cable pulling process, while the drive shaft 6 remains stationary under the action of the one-way bearing 5, preventing the drive disc 7 from rotating with it, and ensuring that the cable pulling operation is easy and smooth.

[0047] Once the test cable 24 is pulled out to the required length, the take-up roller 2 is locked by the ratchet mechanism 22 to prevent the cable from being accidentally retracted or loosened, ensuring that the cable position is stable during the test.

[0048] After the inspection is completed, when it is necessary to rewind the cable, the operator pulls the drive disc 7 upward to separate the first toothed ring 20 on its lower surface from the second toothed ring 21 fixed on the upper surface of the housing 1, thus releasing the locking state. Then, the drive disc 7 is rotated to drive the rotating rod 18 to rotate. The rotating rod 18 drives the drive shaft 6 to rotate through the sliding groove 17. The rotation of the drive shaft 6 is transmitted to the support rod 3 through the one-way bearing 5, which in turn drives the winding roller 2 to rotate, thereby realizing the manual winding of the inspection cable 24.

[0049] As the drive shaft 6 rotates, the second synchronous wheel 15, which is fixedly sleeved outside the drive shaft 6, rotates accordingly. It drives the first synchronous wheel 14 to rotate through the synchronous belt 16. The rotation of the first synchronous wheel 14 drives the transmission shaft 11 to rotate. The first bevel gear 12 and the second bevel gear 13 at the lower end of the transmission shaft 11 mesh, thereby driving the first rotating ring 8 to rotate. The first rotating ring 8 and the second rotating ring 9 are fixedly connected, so the second rotating ring 9 rotates accordingly. Several bristles 10 on its inner ring surface rotate and roll to wipe the surface of the detection cable 24, effectively removing dirt and other impurities from the surface of the cable.

[0050] After winding is completed, the drive disk 7 is released, and the reset spring 19 drives the drive disk 7 to reset, so that the first toothed ring 20 and the second toothed ring 21 re-engage, locking the drive shaft 6 to prevent the cable from coming loose due to misoperation.
