Description

Technical Field

[0001] This utility model relates to the technical field of installation and disassembly tools for power transmission line testing equipment, and in particular to an installation and disassembly tool for an intelligent sensor. Background Technology

[0002] During power system operation, it is necessary to monitor the voltage and current on transmission lines. This is achieved by installing equipment on the transmission lines to collect electrical signals. As users' requirements for power supply reliability increase, power outages should be avoided during installation and removal. Therefore, it is necessary to install and remove equipment while it is energized. Currently, the commonly used monitoring equipment is the intelligent sensor. By utilizing the electromagnetic induction between the transmission line and the intelligent sensor, the corresponding voltage, current, and other parameters are obtained, and the data can be transmitted back. On-site, only the installation or removal of the intelligent sensor on the transmission line is required.

[0003] Traditional installation methods mainly rely on springs to hang the equipment on the power transmission line. Tools such as pry bars are used to manually open the springs and lock them with the installation tools. After the equipment is close to the line, the springs are unlocked. Once the equipment is installed, special tools are used to lock the equipment during disassembly. The operator applies a large downward force to make the springs fall off by themselves. This often requires multiple operations to remove the equipment and can easily cause additional tension on the power transmission line, affecting the stability of the installation. Utility Model Content

[0005] The purpose of this utility model is to provide a tool for installing and removing smart sensors, which solves the problem in the prior art that the sensor is clamped and secured on the power transmission line by a compression spring, and a large pulling force is applied during disassembly to remove it from the power transmission line, which to some extent causes poor installation stability.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tool for installing and removing a smart sensor includes a main structure with a receiving cavity for accommodating the smart sensor, the upper end of which is open. A linkage mechanism for opening or closing the top cover of the smart sensor is mounted on one side of the main structure. An opening / closing drive motor for driving the linkage mechanism to swing is mounted on the main structure. A locking drive motor is mounted at the bottom of the main structure, and a coupling is mounted on the shaft of the locking drive motor. Limiting posts are spaced apart on the coupling, and these limiting posts are used to extend into the locking structure of the smart sensor. A battery and a control circuit board electrically connected to the opening / closing drive motor and the locking drive motor are mounted at the bottom of the main structure. A remote control for wireless communication with the control circuit board is also included.

[0009] Preferably, the bottom of the main structure is provided with a mounting flange, and an operating lever is detachably mounted on the mounting flange.

[0010] Preferably, a camera is mounted on the main structure below the bottom surface of the receiving cavity, the camera is located in the middle of the receiving cavity, and the camera is electrically connected to the control circuit board.

[0011] Preferably, the main structure is equipped with a switch for connecting the battery and the control circuit board.

[0012] Preferably, the main structure is provided with a wedge-shaped structure located at the opening of the receiving cavity.

[0013] Preferably, the main structure has Y-shaped positioning notches on both sides of the opening of the receiving cavity, and the bottom of the positioning notches has an arc notch, the central axis of the arc notch being coaxial with the axis of the wire hole of the smart sensor.

[0014] Preferably, the main structure is provided with multiple shaped holes that connect to the receiving cavity.

[0015] Preferably, the linkage mechanism includes a swing rod, with a first swing arm rotatably mounted at both ends of the swing rod.

[0018] (III) Beneficial Effects

[0019] The smart sensor is placed in the cavity. The opening and closing drive motor drives the linkage mechanism to open or close the top cover of the smart sensor. After the smart sensor is placed on the power transmission cable, the top cover is closed. Then, the locking drive motor drives the coupling to rotate, so that the limit post rotates with the locking structure inside the smart sensor, thereby locking the top cover and locking the entire smart sensor onto the power transmission cable. Then the main structure can be lowered and detached.

[0020] Because the power cables at the installation or disassembly points are quite high, in order to facilitate remote control of the opening and closing drive motor and the locking drive motor, the main structure integrates a battery and control circuit board to achieve the corresponding control. A remote control is also provided so that the remote control signal is sent to the control circuit board for corresponding control. This reduces the number of connecting cables, lightens the weight of the entire tool, and makes it easier to operate. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] See Figures 1-5 As shown in the figure, an embodiment of this utility model proposes an installation and removal tool for a smart sensor 100, used for installing or removing the smart sensor 100 on a power transmission line. Specifically, it includes a main structure 1, which has a receiving cavity 2 for accommodating the smart sensor 100. The upper end of the receiving cavity 2 is open. Moving the main structure 1 allows the smart sensor 100 to be placed into the receiving cavity 2, or detached from the smart sensor 100 and clamped onto the power transmission line. A linkage mechanism 3 for opening or closing the top cover of the smart sensor 100 is installed on one side of the main structure 1. An opening / closing drive motor 4 is installed on the main structure 1 to drive the linkage mechanism 3 to swing. The opening / closing drive motor 4 drives the linkage mechanism 3 to open or close the top cover of the smart sensor 100. The top cover needs to be opened during clamping onto or removal from the power transmission line to allow the power transmission line to be placed into or detached from the smart sensor 100. The linkage mechanism 3 includes a swing rod 31, with a first swing rod 32 rotatably mounted at both ends of the swing rod 31. The first swing rod 32 is rotatably mounted on the main structure 1. Two second swing rods 33 are spaced apart on the swing rod 31, and a drive block 34 is rotatably mounted at the end of each of the second swing rods 33. The opening and closing drive motor 4 is a dual-axis motor, and the rotating shaft of the opening and closing drive motor 4 is fixedly connected to the drive block 34. When the opening and closing drive motor 4 swings with the drive block 34, it pulls the second swing rods 33 to follow the swing and pull the swing rod 31 to move. The movement of the swing rod 31 is simultaneously limited by the range of the first swing rods 32. Therefore, the swing rod 31 can perform an arc swinging action when the opening and closing drive motor 4 rotates forward or backward, thereby realizing the opening or closing operation of the top cover of the smart sensor 100.

[0030] Specifically, a mounting bracket 17 is installed on the main structure 1, and the opening and closing drive motor 4 is installed on the mounting bracket 17. After the opening and closing drive motor 4 is stably installed on the main structure 1 through the mounting bracket 17, it has an installation height relative to the main structure 1, so that the swing range of the drive block 34 is not interfered with by the main structure 1.

[0031] To protect this part, a protective cover 18 is installed on the main structure 1 to shield the opening and closing drive motor 4 and the drive block 34. The protective cover 18 has a swing groove 19 for avoiding the reciprocating swing of the second swing rod 33. Thus, after the protective cover 18 is installed, it will not interfere with the action of the linkage mechanism 3, and effectively protect the opening and closing drive motor 4.

[0032] The top cover of the smart sensor 100 is locked by an internal locking structure using a threaded connection. The top cover is locked or unlocked by rotating the locking structure. Specifically, a locking drive motor 5 is installed at the bottom of the main structure 1. A coupling 6 is mounted on the shaft of the locking drive motor 5. Limiting posts 7 are spaced apart on the coupling 6. The limiting posts 7 extend into the locking structure of the smart sensor 100. When the locking drive motor 5 rotates the coupling 6, the locking structure rotates relative to the limiting posts 7, thereby locking or unlocking the top cover.

[0033] To avoid using long power and control wires, a battery 8 and a control circuit board 9 are electrically connected to the opening / closing drive motor 4 and the locking drive motor 5, respectively, are installed at the bottom of the main structure 1. The battery 8 provides power, while the control circuit board 9 controls the rotation direction and number of rotations of the opening / closing drive motor 4 and the locking drive motor 5 according to instructions. A remote control wirelessly communicates with the control circuit board 9. During installation or disassembly, the tool raised to the power cable can be operated by operating the remote control from the ground, primarily controlling the actions of the opening / closing drive motor 4 and the locking drive motor 5 to close, lock, unlock, or open the top cover of the smart sensor 100. Mature technologies can be used for the electrical control components. This embodiment mainly focuses on enabling the operation of the top cover of the smart sensor 100 in open, closed, locked, or unlocked states to facilitate clamping or disassembly on the power transmission line.

[0034] To facilitate operation by personnel standing on the ground and to adapt to the inspection of power transmission lines at different heights, a mounting flange 10 is provided at the bottom of the main structure 1. An operating rod 11 is detachably mounted on the mounting flange 10. The operating rod 11 of different lengths can be replaced according to the different heights of the power transmission lines and then fixed by the mounting flange 10.

[0035] Specifically, in order to facilitate the alignment of the main structure 1 with the smart sensor 100 at a higher position and ensure that the smart sensor 100 can enter the receiving cavity 2, a camera 12 is installed on the main structure 1 below the bottom surface of the receiving cavity 2. The camera 12 is located in the middle of the receiving cavity 2 and is electrically connected to the control circuit board 9. By adding the camera 12 to collect image information, it is possible to check whether the smart sensor 100 is aligned with the receiving cavity 2 at one end of the remote control, and then move the position of the main structure 1 to improve the convenience of operation.

[0036] To facilitate the guidance during the insertion of the smart sensor 100, a wedge-shaped structure is provided on the main structure 1 at the opening of the receiving cavity 2. The wedge-shaped structure guides the smart sensor 100 as it enters the receiving cavity 2.

[0037] Meanwhile, the main structure 1 is provided with Y-shaped positioning notches 14 on both sides of the opening of the receiving cavity 2. The bottom of the positioning notch 14 is provided with an arc notch 15. The central axis of the arc notch 15 is coaxial with the axis of the wire hole of the smart sensor 100. The positioning notch 14 is used to guide the installation on the power transmission line and ensures that the clamping cavity of the smart sensor 100 is reliably clamped on the power transmission line after the power transmission line is positioned within the arc notch 15.

[0038] In order to shut off the conductivity between the internal battery 8 and the control circuit board 9 when not in use and to avoid accidental operation, a switch 13 for connecting the battery 8 and the control circuit board 9 is installed on the main structure 1. Before each installation or removal of the smart sensor 100, the power supply circuit of the battery 8 must be turned on by the switch 13 before operation can continue. After use, the switch 13 must also be turned off to avoid accidental operation caused by continuous power supply.

[0039] Specifically, the main structure 1 is provided with multiple shaped holes 16 that connect to the receiving cavity 2, which can reduce the weight of the main structure 1, and at the same time, the intelligent sensor 100 can be observed through the shaped holes 16 to see whether it is placed in the receiving cavity 2.
