Description

Technical Field

[0001] This utility model belongs to the technical field of power line safety tools, specifically, it relates to a multi-purpose insulating pull rod. Background Technology

[0002] In the operation and maintenance of power systems, insulated rods (also known as insulated operating rods or link bars) are an essential safety tool used for indirect live-line operations on high-voltage electrical equipment, such as opening and closing high-voltage disconnect switches, installing or removing temporary grounding wires, and replacing fuses, to ensure that operators maintain a sufficient safe distance from live parts.

[0003] A document with publication number (CN204668172U) discloses a multi-purpose insulated pull rod, including a rod body and a pull rod head. One end of the rod body is an insulated handle, and the other end of the rod body is provided with a groove. The connecting end of the pull rod head is provided with a protrusion corresponding to the groove. The protrusion is inserted into the groove, and a pin passes through the groove and the protrusion to fix the rod body and the pull rod head. Through the insertion structure of the groove and the protrusion, and the movable connection of the pin, different pull rod heads can be replaced for different applications. One operating rod can be equipped with multiple pull rod heads, saving costs and making it easy to carry.

[0004] The aforementioned device is installed via a plug-in structure, but this installation method is unstable, leading to inconsistent installation and replacement, which threatens the use of the device. Furthermore, fixed connection methods, such as fasteners, can make device replacement cumbersome.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the problem of replacement technology, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A multi-purpose insulating pull rod includes a replacement assembly for quick replacement. The replacement assembly includes an insulating rod, a rod head, a mounting sleeve, a sliding sleeve, and a snap-fit ​​block. The mounting sleeve is fixedly connected to the insulating rod, the sliding sleeve is elastically connected to the mounting sleeve, the snap-fit ​​block is arranged around the mounting sleeve, and the snap-fit ​​block is drivenly connected to the sliding sleeve. The rod head is inserted into the mounting sleeve and snap-fitted into the snap-fit ​​block.

[0008] In a preferred embodiment of this utility model, the sliding sleeve and the mounting sleeve are slidably connected, the end of the sliding sleeve abuts against the end of the mounting sleeve, and a spring is fitted on the mounting sleeve.

[0009] In a preferred embodiment of this utility model, the ends of the springs abut against the corresponding ends of the sliding sleeves, and the front end of the sliding sleeves is provided with an annular groove.

[0010] In a preferred embodiment of this utility model, the annular groove is used to store the snap-fit ​​block, and a snap-fit ​​groove is provided on the rod head, and the snap-fit ​​block is snapped into place by the snap-fit ​​groove.

[0011] In a preferred embodiment of this utility model, a socket module is provided inside the mounting sleeve, the socket module extends into the insulating rod through a line, and a power interface is provided at the tail end of the insulating rod.

[0012] In a preferred embodiment of this utility model, the power interface is fixedly connected to the insulating rod, the power interface is electrically connected to the line, and a sealing gasket is provided at the tail end of the insulating rod.

[0014] In a preferred embodiment of this utility model, sealing rings are arranged in an array inside the mounting sleeve. The sealing rings are embedded in the inner wall of the mounting sleeve and fit against the wall surface of the rod head.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This multi-purpose insulating pull rod, through a purely mechanical locking mechanism consisting of a sliding sleeve, a spring, and a snap-fit ​​block, achieves "one-click" quick assembly and disassembly between the rod head and the insulating rod. The operation process is smooth, significantly improving the efficiency of tool head replacement. After locking, this mechanical connection can withstand huge pull-out force and torsional force, ensuring the strength of the operation.

[0017] 2. This multi-purpose insulating pull rod, along with the innovative "pre-connection" circuit connection scheme (pull out to connect with the plug module, and then push in as a whole), provides a stable and reliable power and signal channel for the intelligent tool head. The mechanical connection and electrical connection work together to form an efficient and reliable mechatronic quick interface.

[0018] 3. This multi-purpose insulating pull rod integrates a multi-layered safety protection mechanism. First, the mechanical locking is an "active locking" mechanism, effectively preventing the tool head from accidentally getting caught and falling off. Second, the electrical connection incorporates intelligent identification control, ensuring that power is only supplied after the control module verifies its legitimacy, fundamentally avoiding electrical damage caused by mis-insertion. Finally, the sealing ring inside the mounting sleeve and the sealing gasket at the end of the insulating rod form a complete sealing system, providing excellent dust and water resistance for the internal electrical module and ensuring long-term reliable operation of the quick-connect interface in harsh outdoor power operation environments such as humidity and dust.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5 A multi-purpose insulating pull rod includes a replacement assembly for quick replacement. The replacement assembly includes an insulating rod 1, a rod head 2, a mounting sleeve 3, a sliding sleeve 31, and a snap-fit ​​block 33. The mounting sleeve 3 is fixedly connected to the insulating rod 1, the sliding sleeve 31 is elastically connected to the mounting sleeve 3, the snap-fit ​​block 33 is arranged around the mounting sleeve 3, and the snap-fit ​​block 33 is drivenly connected to the sliding sleeve 31. The rod head 2 is inserted into the mounting sleeve 3, and the rod head 2 is snapped into the snap-fit ​​block 33.

[0029] In use, first push the sliding sleeve 31 backward, and the locking block 33 will be unrestricted. Then insert the rod head 2 into the mounting sleeve 3. After the rod head 2 is aligned with the locking block 33, release the force on the sliding sleeve 31. The sliding sleeve 31 will push the locking block 33 inward. Then, the rod head 2 will be tightly locked together by the locking block 33, thus realizing the replacement process. The extension of the rod head 2 is restricted and fixed by the mounting sleeve 3. The subsequent locking method improves the replacement efficiency while ensuring the stability of the connection.

[0030] The sliding sleeve 31 is slidably connected to the mounting sleeve 3, and the end of the sliding sleeve 31 abuts against the end of the mounting sleeve 3. A spring 32 is fitted on the mounting sleeve 3, and the ends of the spring 32 abut against the corresponding ends of the sliding sleeve 31. An annular groove is opened at the front end of the sliding sleeve 31, and the annular groove is used to store the snap-fit ​​block 33. A snap-fit ​​groove 21 is opened on the rod head 2, and the snap-fit ​​groove 21 is snap-fitted with the snap-fit ​​block 33.

[0031] First, push the sliding sleeve 31 away from the insertion port of the mounting sleeve 3; the sliding sleeve 31 then compresses the spring 32 behind it, causing the spring 32 to undergo elastic deformation and store potential energy; at this time, the annular groove on the inner wall of the sliding sleeve 31 is displaced, allowing the multiple locking blocks 33, which were originally constrained inside, to have radial movement space, and the interface is in an unlocked state; then, insert the rod head 2 at one end of the mounting sleeve 3 axially into the interior of the mounting sleeve 3; during the insertion process, the outer wall of the rod head 2 will contact and press the locking block 33, which is already in a movable state, pressing it radially outward, so that it is temporarily housed in the annular groove specially provided at the front end of the sliding sleeve 31; continue to insert the rod head 2 until the radial position of the locking groove 21 and the locking block 33 are completely aligned; after alignment, release the pushing force on the sliding sleeve 31; at this time, the compressed spring 32 releases its stored elastic potential energy, generating a strong The reverse thrust drives the sliding sleeve 31 to automatically reset and slide in the direction of the reverse thrust. During the reset process, the inner wall of the sliding sleeve 31 pushes the locking block 33, causing it to move radially inward and finally firmly lock into the slot 21 of the rod head 2. At the same time, the inner wall of the mounting sleeve 3 covers the extension of the rod head 2, providing the main axial bending resistance support. After connection, the rod head 2 is not only subjected to the radial wrapping force of the inner wall of the mounting sleeve 3, but more importantly, it withstands the continuous and strong radial locking force from the sliding sleeve 31 and the spring 32 through the engagement of the locking block 33 and the slot 21. This design enables the connection to withstand huge pull-out and torsional forces. The locking mechanism is an active locking mechanism, which can only be unlocked and pulled out by pushing the sliding sleeve 31. This effectively prevents the tool head from accidentally falling off due to accidental hooking or accidental contact during operation, constituting an important passive safety mechanism.

[0032] The installation sleeve 3 is equipped with a socket module 11, which extends into the insulating rod 1 through a line. The end of the insulating rod 1 is equipped with a power interface 12, which is fixedly connected to the insulating rod 1 and electrically connected to the line. The end of the insulating rod 1 is equipped with a sealing gasket 13, which abuts against the insulating rod 1. The end of the rod head 2 is fixedly connected with a plug module 22, which is plugged into the socket module 11. The socket module 11 and the plug module 22 are respectively equipped with control modules.

[0033] Before inserting the pole head 2, pull the socket module 11 out of the mounting sleeve 3 a certain distance. Then, after connecting the socket module 11 and the plug module 22, push the socket module 11 and the pole head 2 into the mounting sleeve 3. The control module in the socket module 11 and the plug module 22 identifies and controls whether the power is on. The power supply is provided to the front end through the connection between the line and the power interface 12. In the case of no power, the sealing gasket 13 seals the end of the insulating rod 1.

[0034] It is worth noting that the control module includes: a programmable power supply, a control module, a conversion module, an output port, and a data acquisition module. The programmable power supply is connected to the control module and the conversion module. The conversion module is connected to the output port. The data acquisition module is connected to both the control module and the output port. Specifically, the data acquisition module is used to acquire the voltage information of an external load connected to the output port and send it to the control module. The control module is also used to determine the output voltage of the programmable power supply to the conversion module based on the voltage information and preset reference information. The conversion module is used to convert the output voltage to the operating voltage required for the normal operation of the external load. Thus, by determining the actual situation of the external load through the data acquisition module and adjusting the output voltage of the programmable power supply through the conversion module, the output voltage of the programmable power supply can supply the external load with a voltage sufficient for normal operation. The control module has already been disclosed in the existing controller and detection system CN223427023U, and will not be elaborated upon here.

[0035] The mounting sleeve 3 is provided with an array of sealing rings 34, which are embedded in the inner wall of the mounting sleeve 3 and fit against the wall surface of the rod head 2.

[0036] The connection between the socket module 11 and the plug module 22 is sealed by the sealing ring 34 to prevent short circuits caused by water immersion.

[0037] Working principle: First, push the sliding sleeve 31 away from the insertion port of the mounting sleeve 3; the sliding sleeve 31 then compresses the spring 32 behind it, causing the spring 32 to undergo elastic deformation and store potential energy; at this time, the annular groove on the inner wall of the sliding sleeve 31 is displaced, allowing the multiple locking blocks 33, which were originally constrained inside, to gain radial movement space, and the interface is in an unlocked state; then, insert the rod head 2 at one end of the mounting sleeve 3 axially into the interior of the mounting sleeve 3; during the insertion process, the outer wall of the rod head 2 will contact and press the locking block 33, which is already in a movable state, pressing it radially outward, so that it is temporarily housed in the annular groove specially provided at the front end of the sliding sleeve 31; continue to insert the rod head 2 until the radial position of the locking groove 21 and the locking block 33 are completely aligned; after alignment, release the pushing force on the sliding sleeve 31; at this time, The compressed spring 32 releases its stored elastic potential energy, generating a strong reverse thrust that drives the sliding sleeve 31 to automatically reset and slide in the direction described above. During the reset process, the inner wall of the sliding sleeve 31 pushes the snap-fit ​​block 33, causing it to move radially inward and finally firmly snap into the slot 21 of the rod head 2. This allows for quick replacement. Before inserting the rod head 2, the socket module 11 is pulled out of the mounting sleeve 3 a certain distance. Then, the socket module 11 and the plug module 22 are connected. The socket module 11 and the rod head 2 are pushed into the mounting sleeve 3. The control module in the socket module 11 and the plug module 22 identifies and controls whether the power is on. The power supply is provided to the front end through the connection between the line and the power interface 12. In the case of no power, the sealing gasket 13 seals the end of the insulating rod 1.
