Description

Technical Field

[0001] The invention relates to the technical field of electric power protection, and in particular to an automatic installation fixture for overhead power transmission lines and an installation method thereof. Background Art

[0002] In recent years, there have been frequent casualties of rare wild birds such as black-necked cranes, swans, and gray cranes due to accidental collisions with power transmission lines, and this issue has attracted widespread attention. In order to protect these rare birds and reduce the damage they suffer from accidental collisions with power transmission lines, relevant institutions and researchers have begun to explore and implement a series of measures to prevent accidental bird collisions. At present, it is a common practice to install eye-catching bird-proofing devices on overhead transmission lines, which aims to attract the attention of flying birds through their unique appearance and thus avoid accidental collisions.

[0003] However, the traditional installation method has many shortcomings. First, the installation process is cumbersome. The installation of existing devices usually requires manual installation one by one on the overhead lines during a power outage, which is labor-intensive and inefficient. Second, the installation cost is high and the risk is high. Whether it is directly climbing up the tower for installation or using equipment such as helicopters for installation, there are high costs and risks. The former involves high-altitude operations, which poses a threat to the safety of operators, while the latter has strict requirements on driving skills and equipment safety, and is costly. Third, the installation time is limited. Since power outages are required for operation and power outage plans are subject to many factors, it is difficult to install the bird-proofing device in time.

As a result, the user can easily place the finger or tool between the two protrusions and pry open the clamping portion by applying force, thereby reducing the possibility of misoperation and enhancing the applicability, flexibility and convenience of the clamp.

[0040] In one embodiment, the elastic component includes a first axle pin, a second axle pin, a first spring and a second spring, the first axle pin is inserted into the first clamp arm component 11, the second axle pin is inserted into the second clamp arm 12, one end of the first spring is connected to one end of the first axle pin, the other end of the first spring is connected to one end of the second axle pin, one end of the second spring is connected to the other end of the first axle pin, and the other end of the second spring is connected to the other end of the second axle pin. It should be noted that the first spring and the second spring can work simultaneously to provide uniform elasticity and reset force for the clamping part. When the clamping part is opened by external force, the spring will be stretched and store energy. When the external force disappears, the spring will release energy and push the clamping part to reset. Therefore, the design of the double spring enables the clamping part to maintain better stability when subjected to external force, reduces shaking or deviation caused by vibration or impact, and at the same time, can more effectively disperse and relieve the stress and fatigue generated during the clamping process, thereby extending the service life of the clamp.

[0041] like Figure 6As shown, in one embodiment, it also includes a support frame 2, and a side wall of the first clamp arm assembly 11 away from the second clamp arm 12 and a side wall of the second clamp arm away from the first clamp arm assembly 11 are provided with a mounting groove 149, and the mounting groove 149 is connected with the mounting frame, and the support frame 2 is used to connect the mobile device. It should be noted that the mobile device can drive the clamp through the support frame 2 and the mounting groove 149; the mounting groove 149 is a groove located on the side wall of the first clamp arm assembly 11 and the second clamp arm 12, and its shape, size and position are determined according to the design of the support frame 2; the support frame 2 is any structure that can stably support the clamp, and the structure and size of the support frame 2 are designed according to different types of mobile devices. In this embodiment, preferably, the mounting frame is provided with two horizontal and parallel mounting rods, and the ends of the mounting rods are provided with spherical protrusions, and the mounting rods are used to connect the mounting groove 149; the mobile device can be remotely controlled or not remotely controlled. Preferably, in this embodiment, the mobile device used is a drone. As a result, the clamp can be stably installed on the mobile device, reducing the risk of shaking or falling off due to vibration or impact, improving the versatility and flexibility of the clamp, and at the same time, simplifying the installation process between the clamp and the mobile device, reducing the installation difficulty and cost, and improving the safety of the operation.

At the same time, it can be opened in time in an emergency, thereby enhancing the safety of operation; 6) The use of automated clamps reduces the demand for skilled workers and reduces labor costs, while improving installation speed and quality, thereby reducing the overall installation cost; 7) The modular design of the clamp makes it easy to replace and maintain each component, and also provides convenience for future technological upgrades; 8) The design of the support frame 2 enables the clamp to be easily connected to mobile devices, such as drones, climbing robots, etc., further broadening its application range in different environments and scenarios; 9) The clamp is operated by remote control or preset programs, reducing the risk of operators directly contacting high-voltage lines and dangerous environments, thereby improving the safety of operations.

[0042] A second aspect of the present invention provides an installation method for an automatic installation fixture for an overhead power transmission line, which is described in detail below.

[0043] A method for installing an automatic installation fixture for an overhead power transmission line, based on the automatic installation fixture for an overhead power transmission line provided by any of the above embodiments, comprises the following steps: The first clamp arm assembly 11 and the second clamp arm 12 are rotated so that the clamping portion is opened and the elastic component is stretched. When the clamping portion is opened until the elastic component completes the maximum stretching stroke and retracts, the flexible component is straightened and tightens the first clamp arm assembly 11 and the second clamp arm 12 so that the clamping portion remains in an open state. The side of the flexible component close to the opening of the clamping part is brought into contact with the overhead power transmission line, and the flexible component pulls the first clamp arm component 11 and the second clamp arm 12 to rotate so that the clamping part is closed and the elastic component is stretched. When the elastic component completes the maximum stretching stroke and retracts, the elastic component drives the clamping part to continue to close, so that the clamping part clamps the overhead power transmission line.

[0044] It should be noted that wireless communication technology and remote control technology can be combined to achieve remote operation and monitoring of the fixture. The operator can control the work of the fixture through a remote control or computer interface from a safe distance, thereby improving work safety.

[0045] Therefore, the installation method of the automatic installation fixture for overhead power transmission lines of the present invention solves the technical problems of the prior art such as cumbersome manual installation process, high installation cost, high risk, limited installation time, and limited installation methods, and achieves beneficial effects: 1) through the synergistic effect of the pulling of the flexible component and the retraction of the elastic component, the open state of the fixture is stably maintained and the clamping operation is completed quickly and firmly, which greatly improves the installation efficiency; 2) compared with the traditional manual installation method, the installation method is simpler and faster, reduces the requirements for the skills and experience of the operator, and at the same time, reduces the time of high-altitude operations, thereby reducing the installation risks and safety hazards caused by human factors; 3) the shortening of the installation time shortens the power outage time, thereby reducing the constraints caused by the power outage operation; 4) the mutual cooperation of the flexible component and the elastic component ensures the uniform distribution and stable transmission of the clamping force, which not only improves the stability of the installation, but also effectively avoids the line damage caused by uneven clamping force and the installation failure or line damage caused by inaccurate alignment, ensuring the accuracy and reliability of the installation; 5) it is suitable for the installation of overhead power transmission lines of different specifications and types.

[0046] like Figure 1-6 As shown, an optional working process of the automatic installation fixture for overhead power transmission lines and the installation method thereof in the present invention is as follows: In the initial state, under the action of the first spring, the second spring, the first shaft pin and the second shaft pin, the clamping portion formed by the first clamping arm assembly 11 and the second clamping arm 12 is closed, and the hook 13 is hooked in the hook slot 121; Hold the second protrusion 148 of the first clamp arm assembly 11 with the left hand, hold the second protrusion 148 of the second clamp arm 12 with the right hand, and carefully pry open the clamp so that the clamping part is opened and the first spring and the second spring are stretched. When the clamping part is opened to the point where the first spring and the second spring complete the maximum stretching stroke, continue to open the clamping part, and the angle formed by the first connecting hole 144 respectively located on the first clamp arm assembly 11 and the second clamp arm 12 and the first rotating shaft 16 in the opening direction close to the clamping part is greater than 180°, so that the first spring and the second spring retract along the angle away from the opening direction of the clamping part, and the rope is in a taut state and the first clamp arm assembly 11 and the second clamp arm 12 are tightened through the hook 13 and the hook slot 121, so that the clamping part remains in an open state; The support frame 2 is installed on the drone, and the clamping part is installed on the support frame 2 through the installation groove 149. The drone is controlled to drive the clamping part to reach under the overhead cable and align the opening of the clamping part with the overhead transmission line. The drone moves upward to drive the clamping part to move upward so that the overhead transmission line enters the clamping part, and the side of the rope close to the opening of the clamping part is abutted against the overhead transmission line. The rope pulls the first clamp arm assembly 11 and the second clamp arm 12 to rotate so that the clamping part is closed and the first spring and the second spring are stretched. When the first spring and the second spring complete the maximum stretching stroke and retract, the first spring and the second spring drive the clamping part to continue to close, so that the clamping part clamps the overhead transmission line.
