These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0028] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0029] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0030] In the prior art, in order to make the internal space of the cabinet neat and orderly, the transmission line is generally installed from the bottom of the cabinet and passed through the installation hole reserved at the bottom of the cabinet from bottom to top, so as to complete the laying of the transmission line. When installing the transmission line, the maintenance personnel usually directly pass the end of the transmission line through the installation hole by hand to complete the laying of the transmission line. However, with the subsequent laying of a large number of transmission lines, the space at the bottom of the cabinet becomes more and more limited, making it difficult for maintenance personnel to find the previously reserved installation hole from the front of the cabinet when adding or replacing network cables. Even if the installation hole can be found, the already laid transmission lines occupy a large amount of installation space, making it difficult to place the new transmission line into the installation hole for perforation installation. In addition, in this process, it is also easily obstructed by the already laid transmission lines, making the installation of the new transmission line more difficult.

[0031] In view of the above technical problems, the embodiment of the present application provides an auxiliary threading device, including a positioning member and a pulling member, wherein the positioning member can be connected to the end of the transmission line, and the pulling member includes a pulling tube and a probe seat provided at one end of the pulling tube. The pulling member can pass through the installation hole from top to bottom, so that the probe seat is connected to the positioning member, and then by pulling the pulling member, the transmission line can be passed through the installation hole of the cabinet from bottom to top, thereby realizing the rapid installation of the transmission line and reducing the difficulty of installation.

[0032] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0033] See also Figure 1 An embodiment of the present application provides an auxiliary threading device, which includes a positioning member 100 and a pulling member 200.

[0034] The positioning member 100 is provided with an installation groove 101, which is used to install the end of the transmission line; the pulling member 200 includes a pulling tube 210 and a probe seat 220, the probe seat 220 is arranged at one end of the pulling tube 210, the probe seat 220 is provided with a first connecting part 201, the positioning member 100 is provided with a second connecting part 102, and the first connecting part 201 can be detachably connected to the second connecting part 102, so that the probe seat 220 is connected to the positioning member 100.

[0035] The positioning member 100 is fixed to the end of the transmission line and can be connected to the pulling member 200 so that the pulling member 200 drives the transmission line through the mounting hole. The mounting groove 101 on the positioning member 100 is used to mount the end of the transmission line, and its diameter can be slightly larger than the outer diameter of the transmission line so that the transmission line can be easily placed and fixed in the mounting groove 101.

[0036] The pulling member 200 includes a pulling tube 210 and a probe seat 220. The pulling tube 210 is slender and its length can be adjusted according to actual needs. The pulling tube 210 can be made of a lightweight and elastic metal material to ensure that it can be flexibly bent and manipulated during the threading process, thereby adapting to various complex threading environments.

[0037] The first connection portion 201 of the probe base 220 is detachably connected to the second connection portion 102 of the positioning member 100 , so that the probe base 220 is connected to the positioning member 100 .

[0038] The first connection part 201 is the part where the probe base 220 is connected to the positioning member 100, and the second connection part 102 is the part where the positioning member 100 is connected to the probe base 220. The first connection part 201 and the second connection part 102 are connected by a detachable structure. Exemplarily, the detachable structure can be a buckle structure, a hook and slot structure, a threaded sleeve structure, etc. For example, the first connection part 201 is a buckle, and the second connection part 102 is a slot.

[0039] In actual use of this embodiment, during the maintenance and installation of the transmission line, the maintenance personnel can insert the end of the transmission line into the installation groove 101 to fix the transmission line. When threading is required, the maintenance personnel pass the probe seat 220 of the pulling member 200 from top to bottom under the installation hole, and then use the magnetic connection between the probe seat 220 of the pulling member 200 and the positioning member 100, and then drive the transmission line through the installation hole through the pulling tube 210. When the positioning member 100 and the transmission line reach the target position, the pulling member 200 and the positioning member 100 are manually separated, and then the transmission line is taken out of the installation groove 101 of the positioning member 100, and the threading work is completed.

[0040] This embodiment realizes a detachable connection between the positioning member 100 and the pulling member 200, thereby realizing that the positioning member 100 and the pulling member 200 can be quickly connected and separated, and can quickly and accurately complete the task of threading the transmission line, reducing the complexity and labor intensity of manual operation, and effectively reducing the difficulty of laying and installing the transmission line, and improving the installation efficiency.

[0041] In some embodiments, one of the first connection part 201 and the second connection part 102 is an adsorbent, and the other is an adsorbed part that can be adsorbed by the adsorbent; or, both the first connection part 201 and the second connection part 102 are adsorbents, and the magnetic properties of the first connection part 201 and the second connection part 102 are opposite.

[0042] The first connection part 201 and the second connection part 102 are connected and separated by magnetic attraction, thereby realizing a detachable connection. Specifically, one of the first connection part 201 and the second connection part 102 is an adsorbing part, and the other is an adsorbed part. The adsorbing part has sufficient magnetism and can firmly adsorb the adsorbed part. Exemplarily, the adsorbing part is a magnet or an electromagnet 225, and the adsorbed part is a ferromagnetic metal such as iron, nickel, and cobalt. In this way, the first connection part 201 and the second connection part 102 can be magnetically matched.

[0043] In another embodiment, the first connection part 201 and the second connection part 102 are both designed as adsorbents, but their magnetism is opposite. In this way, the two connection parts automatically align and adsorb together when they are close to each other, further simplifying the connection process. For example, if the first connection part 201 has N-pole magnetism and the second connection part 102 has S-pole magnetism, they will align and adsorb when they are close to each other, achieving a stable connection.

[0044] It can be understood that the first connection part 201 and the second connection part 102 are detachably connected by means of magnetic attraction and the detachable structure, which is beneficial to improving the connection strength.

[0045] In some embodiments, see Figure 2 and Figure 3 The positioning member 100 includes a positioning member body 110, a first shell 120 and a second shell 130, wherein the first shell 120 and the second shell 130 are disposed on the positioning member body 110, wherein the first shell 120 and the second shell 130 are disposed relatively spaced apart and surround a mounting groove 101.

[0046] The positioning member body 110 is the main structure of the positioning member 100, and is used to fix the first shell 120 and the second shell 130. The mounting groove 101 is formed by the first shell 120 and the second shell 130, and is used to install the end of the transmission line. The mounting groove 101 allows the end of the transmission line to be placed, and its diameter is slightly larger or slightly smaller than the outer diameter of the transmission line. The first shell 120 and the second shell 130 are arranged relatively spaced apart, and the first shell 120 and the second shell 130 can provide expansion space for larger-sized transmission lines through deformation, so that the positioning member 100 can adapt to transmission lines of various outer diameters.

[0047] Exemplarily, the positioning member 100 is cylindrical, the positioning member body 110, the first shell 120 and the second shell 130 are an integral structure, the first shell 120 and the second shell 130 are arranged oppositely on both radial sides of the positioning member 100, and the mounting groove 101 extends from between the two shells to the positioning member body 110 along the length direction of the positioning member 100. When in use, the positioning member 100 can be sleeved on the end of the transmission line through the mounting groove 101.

[0048] In some embodiments, a slide groove 140 is provided on at least one of the first shell 120 and the second shell 130, and the extension direction of the slide groove 140 is inclined relative to the extension direction of the installation groove 101; a clamping rod 150 is provided in the slide groove 140, and the clamping rod 150 moves along the extension direction of the slide groove 140 to abut against the transmission line located in the installation groove 101.

[0049] The extension direction of the slide groove 140 is inclined relative to the extension direction of the installation groove 101. When the positioning member 100 drives the transmission line to move, there is friction between the clamping rod 150 and the slide groove 140 in the extension direction of the slide groove 140, which is beneficial to ensure that the clamping rod 150 is fixed at the specified position and prevent the clamping rod 150 from loosening.

[0050] The clamping rod 150 can move freely in the slide groove 140. According to the size and shape of the transmission line, the maintenance personnel can adjust the position of the clamping rod 150 to ensure that the transmission line is effectively fixed and improve the fixing stability of the transmission line. Specifically, when the transmission line is placed in the installation groove 101, the clamping rod 150 moves to the position of the transmission line and abuts against it, providing additional fixing force to ensure the stability of the transmission line during the threading operation.

[0051] In some embodiments, the first housing 120 and the second housing 130 are both provided with a slide groove 140, and the slide grooves 140 on the first housing 120 and the second housing 130 are symmetrically arranged, and the clamping rods 150 in the two slide grooves 140 are used to jointly clamp the transmission line located in the installation groove 101. The two clamping rods on the first housing 120 and the second housing 130 clamp the transmission line in the installation groove 101 together, which is conducive to ensuring the installation stability of the transmission line and reducing the occurrence of the transmission line falling off, thereby improving the fixing strength of the positioning member 100 to the transmission line.

[0052] In some embodiments, not shown in the figures, the auxiliary threading device also includes a threaded sleeve, and the outer peripheral wall of the first shell 120 and the outer peripheral wall of the second shell 130 are both provided with external threads, and the threaded sleeve is arranged on the first shell 120 and the second shell 130, and is threadedly connected to the first shell 120 and the second shell 130.

[0053] By sleeve-fitting the threaded sleeve on the outer circumference of the first shell 120 and the second shell 130, the relative distance between the first shell 120 and the second shell 130 is fixed, and the size of the installation groove 101 between the first shell 120 and the second shell 130 is defined, which is conducive to ensuring the fit between the transmission line and the groove wall of the installation groove 101, thereby allowing the transmission line to be stably installed in the installation groove 101. At the same time, since the threaded sleeve connects the first shell 120 and the second shell 130 as a whole, the structural stability of the first shell 120 and the second shell 130 is enhanced, which is conducive to maintaining the stability of the positioning member 100 during the movement process.

[0054] Exemplarily, the external threads of the outer peripheral wall of the first shell 120 and the outer peripheral wall of the second shell 130 are both in a cone shape, and along the length direction of the positioning member 100, the outer diameters of the first shell 120 and the second shell 130 gradually decrease, and accordingly, the internal threads of the threaded sleeve are adapted to the external threads and are also in a cone shape. In this way, when the threaded connection depth between the threaded sleeve and the first shell 120 and the second shell 130 is greater, the first shell 120 and the second shell 130 are closer to each other, and the space of the installation groove 101 is relatively reduced, thereby increasing the clamping force of the first shell 120 and the second shell 130 on the transmission line, which is conducive to improving the installation stability between the transmission line and the positioning member 100. When the relative position of the first shell 120 and the second shell 130 needs to be adjusted, the maintenance personnel can achieve it by rotating the threaded sleeve, thereby adjusting the size and shape of the installation groove 101 to adapt to different transmission lines. In addition, when the size of the transmission line is large, the transmission line can be better fixed in the installation groove 101 by the threaded sleeve.

[0055] In some embodiments, due to the low light environment, in order to improve the detection and control performance of the threading operation, please refer to Figure 4 and Figure 5 The probe seat 220 includes a camera 221, a light source 222, a circuit board 223 and a seat body 224. The camera 221, the light source 222 and the circuit board 223 are all installed on the seat body 224, and the camera 221 and the light source 222 are electrically connected to the circuit board 223; an inner cavity is provided in the seat body 224, and an electromagnet 225 is provided in the inner cavity, and the electromagnet 225 is electrically connected to the circuit board 223.

[0056] The seat body 224 is the main structure of the probe seat 220, and is used to install the camera 221, the light source 222 and the circuit board 223. The circuit board 223 includes electronic components for controlling the camera 221 and the light source 222, and a circuit connected to the electromagnet 225. The camera 221 is used to capture real-time images during the threading process, so as to quickly find the positioning member 100. The camera 221 is electrically connected to the circuit board 223, so that the image captured by the camera 221 can be transmitted to an external display device through the circuit board 223, which is beneficial for maintenance personnel to observe and monitor the laying of the transmission line. The light source 222 can provide sufficient lighting so that the camera 221 can clearly capture images even in an environment with insufficient light. The light source 222 is electrically connected to the circuit board 223, and the opening and brightness adjustment of the light source 222 can be controlled by the circuit board 223. The inner cavity provides space for the electromagnet 225 and other electronic components, and the electromagnet 225 is electrically connected to the circuit board 223 to realize the magnetic connection between the probe seat 220 and the positioning member 100.

[0057] This embodiment enhances the monitoring and control capabilities of the threading operation through the integrated design of the probe holder 220, which helps to improve the maintenance quality and efficiency of the secondary cabinet equipment of the power system substation.

[0058] In some embodiments, a first switch 231 and a second switch 232 are provided at one end of the pulling tube 210 away from the probe base 220 . The first switch 231 is electrically connected to the electromagnet 225 , and the second switch 232 is electrically connected to the camera 221 and the light source 222 .

[0059] The first switch 231 allows the maintenance personnel to activate the electromagnet 225 before threading, ensuring a stable connection between the probe seat 220 and the positioning member 100, and conveniently disconnecting the connection after threading is completed. The second switch 232 allows the maintenance personnel to control the operation of the camera 221 and the light source 222 according to actual conditions, improve the monitoring efficiency of the threading process and adapt to different working environments. Of course, the first switch 231 and the second switch 232 can also be connected to the circuit board 223 to indirectly control the electromagnet 225, the camera 221 and the light source 222.

[0060] This embodiment not only improves the efficiency and stability of the threading process by setting the first switch 231 and the second switch 232 on the pulling tube 210, but also enhances the flexibility and controllability of the threading operation through centralized control of the switches, which helps to improve the maintenance quality and efficiency of the secondary cabinet equipment of the power system substation.

[0061] In some embodiments, see Figure 4 The pulling member 200 further includes a handle 230 , which is disposed at one end of the pulling tube 210 away from the probe seat 220 .

[0062] The handle 230 is disposed at one end of the pulling tube 210 away from the probe base 220, providing a gripping point for maintenance personnel during operation. Through the handle 230, maintenance personnel can more effectively transmit force to the pulling tube 210, so as to facilitate control of the pulling force of the transmission line. The shape and size of the handle 230 can be designed based on ergonomics to adapt to the hand shape and holding habits of different operators.

[0063] Exemplarily, the first switch 231 and the second switch 232 may be disposed on the handle 230 , so that the maintenance personnel may control the switch and the handle 230 simultaneously in a single-handed operation, thereby improving the convenience of operation.

[0064] In some embodiments, the pulling tube 210 is an elastic tube. The pulling tube 210 can be made of a material with good elasticity, such as spring steel, elastic plastic or other highly elastic materials, to ensure that it can provide appropriate elastic restoring force during use. During the threading process, the elastic pulling tube 210 can absorb part of the impact force and reduce potential damage to the transmission line and equipment.
