However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figure 1-2 This is the first embodiment of the present utility model. This embodiment provides a take-up and put-down device, a rotating component 100, which includes a support plate 101, a fixing plate 102 disposed above the support plate 101, and a driving component 103 disposed above the support plate 101.

[0029] There are two support plates 101. The two support plates 101 are fixedly connected to both ends of the fixed plate 102 respectively. A part of the drive assembly 103 is located above the upper support plate 101. The other part of the drive assembly 103 passes through the upper support plate 101 and is fixedly connected to the lower support plate 101. The drive assembly 103 is used to enable the cable to be wound up.

[0030] The adjusting component 200 includes a linkage component 201 located above the support plate 101 and connected to the drive component 103, a synchronization component 202 located below the linkage component 201 and connected to the linkage component 201, and a lifting component 203 located inside the fixed plate 102 and connected to the lifting component 203.

[0031] When it is necessary to wind up the cable, the drive assembly 103 is activated first to wind up the cable. Through the cooperation between the linkage assembly 201, the synchronization assembly 202 and the lifting assembly 203, the cable can be guided and straightened at the same time as it is being wound up, so as to ensure that the cable will not get tangled during winding.

[0032] Furthermore, the drive assembly 103 includes a rotating shaft 102a disposed above the support plate 101, a turntable 102b disposed outside the rotating shaft 102a, and a rotating handle 102c disposed at one end of the rotating shaft 102a. The rotating shaft 102a is rotatably connected to the lower support plate 101 and is connected by ball bearings. The durability of the ball bearings improves the service life of the device. The turntable 102b is fixedly connected to the rotating shaft 102a. The cable is wound up above the turntable 102b. The rotating handle 102c is disposed above the upper support plate 101 and is fixedly connected to the rotating shaft 102a. The rotating handle 102c is provided with anti-slip texture. The rotation of the rotating handle 102c drives the rotating shaft 102a to start winding the cable.

[0033] Furthermore, the linkage component 201 includes a pulley 201a located below the rotating handle 102c, a rotating shaft 201d located above the fixed plate 102, a pulley 201b located outside the rotating shaft 201d, and a belt 201c located between the pulley 201a and the pulley 201b. The belt is fixedly connected to the rotating shaft 102a, and the rotating shaft 201d is connected to the synchronization component 202. The rotation of the rotating handle 102c drives the pulley 201a to rotate, and the belt 201c drives the pulley 201b to rotate, thereby driving the rotating shaft 201d to rotate, which in turn drives the synchronization component 202 to move. The linkage component converts the rotational force generated by the drive component 103 into the power for the synchronization component 202 to move.

[0034] Furthermore, the synchronization assembly 202 includes a first synchronous pulley 202a located below the rotating shaft 201d, a screw 202e located inside the support plate 101, a second synchronous pulley 202b located on one side of the first synchronous pulley 202a, a third synchronous pulley 202c located on the other side of the first synchronous pulley 202a, and a synchronous belt 202d located between the second synchronous pulley 202b and the third synchronous pulley 202c; wherein the first synchronous pulley 202a and the synchronous belt 202d cooperate with each other, and the screw 202e... There are two timing pulleys 202e, 202b and 202c, which are fixedly connected to the screw 202e. The rotating shaft 201d drives the timing pulley 202a to rotate, which in turn drives the timing pulleys 202b and 202c to rotate, which in turn drives the screw 202e to rotate. The above design ensures that the two screws 202e rotate at the same speed, thus ensuring that the lifting assembly 203 can lift vertically without deviation.

[0035] Furthermore, the lifting assembly 203 includes a sliding groove 203b on both sides of the fixed plate 102 and a lifting block 203a between the fixed plates 102; wherein, the two ends of the lifting block 203a are slidably disposed inside the sliding groove 203b, and the lifting block 203a is threadedly connected to the screw 202e, and the thread size and direction are the same.

[0036] Operating procedure: When it is necessary to wind up the cable, first rotate the handle 102c clockwise to drive the rotating shaft 102a to rotate. One end of the cable is fixed on the rotating shaft 102a, so the cable will rotate around the shaft, thereby winding up the cable. The rotation of the handle 102c drives the pulley 201a to rotate. Through the transmission of the belt 201c, the pulley 201b rotates, which drives the rotating shaft 201d to rotate. The rotating shaft 201d drives the synchronous pulley 202a to rotate, which in turn drives the synchronous pulleys 202b and 202c to rotate, which in turn drives the screw 202e to rotate, thereby causing the lifting block 203a to move upward inside the slide groove 203b.

[0037] When the cable is wound up to the top, rotate the handle 102c in the opposite direction. Following the same operating procedure, the lifting plate moves downward inside the slide 203b, thereby guiding the cable winding.

[0038] Example 2

[0039] Reference Figures 1-4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a neutral wire breakage fault monitoring device; it also includes a cleaning component 300, which includes a drive component 103 disposed inside the slide 203b, and a cleaning component 302 disposed inside the lifting block 203a and connected to the drive component 103. Through the design of the drive component 103, the cleaning component 302 can be driven to clean the outer surface of the cable during the lifting process.

[0040] Specifically, the drive assembly 103 includes a rack 301a mounted on the inner wall of the slide 203b, a drive shaft 301d mounted on one end of the lifting block 203a, a drive gear 301b mounted on the outer side of the drive shaft 301d, and a pulley 301c mounted on one end of the drive shaft 301d. The rack 301a is fixedly connected to the inner wall of the slide 203b, the drive shaft 301d is rotatably connected to the lifting block 203a, and the drive gear 301b meshes with the rack 301a. When the lifting block 203a moves downward, the drive gear 301b rotates due to the contact between it and the rack 301a, thereby driving the drive shaft 301d to rotate, which in turn drives the pulley 301c to rotate. The pulley 301c then drives the cleaning assembly 302 to clean the cable.

[0041] Furthermore, the cleaning component 302 includes a fixed block 302e located at the upper end of the lifting block 203a, a fixed shaft 302f located on one side of the fixed block 302e, a pulley 302a located outside the fixed shaft 302f, a belt 302b located between the pulley 302a and the pulley 301c, a linkage gear 302c located at one end of the fixed shaft 302f, a cylinder 203c located inside the lifting block 203a, and a cylinder 203c located outside the cylinder 203c. The external gear 302d, the fixed block 302e and the lifting block 203a are fixedly connected, the fixed shaft 302f and the fixed block 302e are rotatably connected, and the pulley 302a is fixedly connected to the fixed shaft 302f. The rotation of the pulley 301c drives the pulley 302a to rotate, thereby driving the linkage gear 302c to rotate. Thus, the external gear 302d drives the cylinder 203c to rotate in the lifting block 203a, thereby cleaning the outer surface of the cable.

[0042] The rest of the structure is the same as in Example 1.

[0043] Example 3

[0044] Reference Figures 1-5 This is the third embodiment of the present invention. Unlike the previous embodiment, the inside of the cylinder 203c is provided with a cleaning brush 303. The cleaning brush 303 is a soft brush used to protect the outer surface of the cable.

[0045] Specifically, a bidirectional drive motor 400 is provided at the upper end of the rotating shaft 102a. The bidirectional drive motor 400 is fixedly connected to the rotating shaft 102a, which can save manpower and ensure stable forward and reverse rotation through a set program.

[0046] The remaining structures are the same as those in Example 1 or 2.
