Description

Technical Field

[0001] This utility model belongs to the field of inductive electricity and relates to inductive electricity detection technology, specifically an inductive electricity detection pole for substation lines. Background Technology

[0002] The reference patent is titled: "A Substation Line Inductive Electricity Detection Rod" (Patent Publication No.: CN217404392U). It detects induced electricity data on the surface of the line by including a collection rod, a connector assembly, a step-down rod, and an independent substation line induced electricity data display device. The connector assembly includes two sawtooth-shaped collection connectors, which make contact with the line to achieve induced electricity contact, and then display the induced electricity value through the data display device.

[0003] However, the following problems exist when implementing the above technical solution: In the above solution, the upper and lower sawtooth-shaped acquisition connectors that contact the line are directly set on the surface of the acquisition rod. Therefore, if you want to change their spacing, you need to adjust the position of the detection rod before use. When adjusting in advance, in order to ensure that the line can be inserted between the two acquisition connectors, the gap between them needs to be slightly larger than the line diameter. Therefore, during the measurement process, you need to manually ensure the position of the acquisition rod to avoid instability between the detection rod and the line during measurement, which would affect the results. As a result, the acquisition rod and acquisition connectors are inconvenient to use.

[0004] Therefore, this utility model proposes a substation line induction detection rod. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a substation line inductive current detection rod, which solves the problem that the distance of the acquisition connector, which is in contact with the line on the surface of the inductive current detection rod, can only be adjusted at the top of the detection rod, making it inconvenient to use.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a substation line induced current detection pole is provided, comprising a data acquisition pole, a voltage reduction pole, and a telescopic pole; a clamping mechanism is provided between the data acquisition pole and the telescopic pole, the clamping mechanism comprising:

[0007] The upper connector is fixed to the surface of the collection rod;

A central rotating wheel is rotatably connected inside the support rod. The surface of the central rotating wheel is slidably connected to the connecting belt.

[0009] A winding rod is rotatably connected to a telescopic rod. An operating rod is slidably connected inside the telescopic rod. A reversing cone wheel is fixedly connected to both the end of the operating rod near the winding rod and the end of the winding rod away from the pressure reducing rod. The reversing cone wheels mesh with each other.

[0010] Optionally, a sliding shaft is fixedly connected to the surface of the lower connector, and a sliding groove is provided on the surface of the collecting rod, the sliding groove being adapted to the sliding shaft and the lower connector.

[0011] Optionally, the support rod has a cylindrical groove on its surface, the diameter of which is equal to the diameter of the central rotating wheel, and the central rotating wheel has a winding groove on its surface, the width of which is greater than the width of the connecting belt.

[0012] Optionally, the surface of the winding rod is provided with a guide groove, the guide groove is J-shaped, and the guide groove is adapted to the connecting belt.

[0013] Optionally, a limiting ring is slidably connected to the surface of the operating rod, and an arc-shaped groove is formed on the surface of the limiting ring.

[0014] Optionally, the operating lever has a moving groove on its surface, and a moving shaft is fixedly connected inside the limiting ring, the moving shaft being adapted to the moving groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: a fixed upper connector and a movable lower connector are set on the surface of the acquisition rod. The position of the overall inductive current detection rod can be initially defined by the contact between the upper connector and the line surface. A connecting belt is set on the surface of the lower connector. The connecting belt changes direction through the central rotating wheel and connects to the winding rod located on the surface of the telescopic rod. Thus, the position of the lower connector can be changed by the rotation of the lower winding rod. Furthermore, the operating direction and position can be changed by the reversing cone wheel on one side of the winding rod and the telescopic rod, which is more conducive to daily operation. The position of the operating rod can be set according to needs, making it more flexible. Attached Figure Description

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] like Figure 1-7 As shown, a substation line induction detection pole includes a data acquisition pole 1, a voltage reduction pole 2, and a telescopic pole 3;

[0031] It should be noted that all telescopic rods 3 are made of insulating material; and all collecting rods 1 are made of conductive material.

[0032] A clamping mechanism is provided between the collecting rod 1 and the telescopic rod 3, and the clamping mechanism includes:

[0033] Upper connector 41, which is fixed to the surface of the collection rod 1;

[0034] The lower connector 42 is slidably connected to the collection rod 1. A connecting belt 43 is fixedly connected inside the lower connector 42. The connecting belt 43 is slidably connected to the inside of the collection rod 1. A support rod 44 is fixedly connected to the side of the collection rod 1 away from the pressure reducing rod 2. A central rotating wheel 45 is rotatably connected inside the support rod 44. The surface of the central rotating wheel 45 is slidably connected to the connecting belt 43.

[0035] A take-up rod 46 is rotatably connected to a telescopic rod 3. An operating rod 47 is slidably connected inside the telescopic rod 3. A reversing cone wheel 48 is fixedly connected to both the end of the operating rod 47 near the take-up rod 46 and the end of the take-up rod 46 away from the pressure reducing rod 2. The reversing cone wheels 48 mesh with each other. The take-up rod 46 is a telescopic rod.

[0036] In practical application, the substation line inductive current detection rod has a fixed upper connector 41 and a movable lower connector 42 on the surface of the acquisition rod 1. The contact between the upper connector 41 and the line surface initially defines the position of the overall inductive current detection rod. The lower connector 42 is provided with a connecting belt 43, which changes direction through the central rotating wheel 45 and connects to the winding rod 46 located on the surface of the telescopic rod 3. Thus, the position of the lower connector 42 can be changed by the rotation of the lower winding rod 46. The operating direction and position can be changed through the reversing cone wheel 48 on the side of the winding rod 46 and the telescopic rod 3, which is more conducive to daily operation. The position of the operating rod 47 can be set according to needs, making it more flexible.

[0037] In some specific implementations, a sliding shaft 51 is fixedly connected to the surface of the lower connector 42, and a sliding groove 52 is provided on the surface of the collecting rod 1. The sliding groove 52 is adapted to the sliding shaft 51 and the lower connector 42.

[0038] In some specific implementations, the support rod 44 has a cylindrical groove 61 on its surface, the diameter of which is equal to the diameter of the central rotating wheel 45. The central rotating wheel 45 has a winding groove 62 on its surface, the width of which is greater than the width of the connecting belt 43. The cylindrical groove 61 and the winding groove 62 restrict the movement of the connecting belt 43, providing sufficient space for movement and sliding, and preventing the connecting belt 43 from detaching from the surface of the central rotating wheel 45 and causing the central rotating wheel 45 to become stuck.

[0039] In some specific implementations, the retractable rod includes a base rod, an intermediate rod, and a connecting rod. Both the base rod and the intermediate rod are rotatably connected with threaded rods, and the two threaded rods are slidably connected to each other. The intermediate rod is threadedly connected to the threaded rod inside the base rod, and the connecting rod is threadedly connected to the threaded rod inside the intermediate rod.

[0040] In a further embodiment, the take-up rod 46 includes a base shaft, an intermediate shaft, and a connecting shaft. The base shaft and the intermediate shaft are slidably connected, and the intermediate shaft and the connecting shaft are also slidably connected. One end of the base shaft away from the intermediate shaft is fixedly connected to the reversing cone wheel 48. A guide groove 71 is provided on the surface of the connecting shaft. The guide groove 71 is J-shaped and is adapted to the connecting belt 43. Rotary bearings (not shown in the figure) are fixedly connected inside the base rod, the intermediate rod, and the connecting rod. The surface of the base shaft engages with the inner ring of the rotary bearing (not shown in the figure) inside the base rod. The surface of the intermediate shaft engages with the inner ring of the rotary bearing (not shown in the figure) inside the intermediate rod. The surface of the connecting shaft engages with the inner ring of the rotary bearing (not shown in the figure) inside the connecting rod. The J-shaped guide groove 71 on the surface of the take-up rod 46 can keep the initial contact position of the connecting belt 43 and the take-up rod 46 away from the pressure reducing rod 2, avoiding long-term sliding contact between the connecting belt 43 and the pressure reducing rod 2, which could cause damage to the insulating material on the surface of the pressure reducing rod 2.

[0041] In some specific implementations, a limiting ring 81 is slidably connected to the surface of the operating rod 47, and an arc-shaped groove 82 is formed on the surface of the limiting ring 81. A plurality of limiting posts 83 are fixedly connected to the surface of the base rod, and the limiting posts 83 are adapted to the arc-shaped groove 82.

[0042] In a further embodiment, the operating lever 47 has a moving groove 84 on its surface, and a moving shaft 85 is fixedly connected inside the limiting ring 81, the moving shaft 85 being adapted to the moving groove 84;

[0043] The working principle of this utility model is as follows: When measuring the line, firstly, the upper connector 41 is brought into contact with the upper side of the line. Then, the sliding limit ring 81 is used to disengage the limit post 83 from the arc groove 82. At this time, the operating rod 47 can be rotated. The rotation of the operating rod 47 will drive the winding rod 46 to rotate through the reversing cone wheel 48. The rotation of the winding rod 46 will cause the connecting belt 43 to wrap around its surface. Then, the connecting belt 43 pulls the lower connector 42 to move the upper connector 41. After the lower connector 42 contacts the lower side of the line, the connecting belt 43 can no longer move. At this time, the limit ring 81 is pressed to make the limit post 83 slide into the arc groove 82, which can limit the rotation of the operating rod 47 again. Then, the position of the lower connector 42 is fixed. The lower connector 42 and the upper connector 41 clamp the line, ensuring that the position of the induced current detection rod and the line is fixed.

[0044] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
