Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a safety net with adjustable feet. Background Technology

[0002] In the field of power equipment safety protection, the application of safety fencing is crucial, especially around power facilities such as substations, power plants, and high-voltage lines, to prevent personnel from accidentally entering high-voltage areas or to protect equipment from external interference. However, existing safety fencing technologies have several key problems in practical applications with power equipment: Insufficient angle adaptability: Traditional safety fencing is usually designed with a fixed angle, making it impossible to adjust the angle according to the specific placement of power equipment or changes in terrain. This fixed nature limits its application flexibility when facing complex power facility layouts or when the fencing needs to be installed at an angle to adapt to the height and position of equipment, resulting in poor performance in actual use; Complex installation and adjustment: The installation process of existing power safety fencing often requires specialized tools and a long time, especially when the angle of the fencing needs to be adjusted to adapt to different equipment or terrain. The operation process is cumbersome, affecting installation efficiency and ease of use. This inconvenience is particularly prominent during power equipment maintenance or emergency repairs, which may delay important operations; Stability and safety issues: Fixed-angle fencing is prone to stability problems on the ground around power equipment, especially when the ground is uneven or sloping. Especially in strong winds or when subjected to external impacts, the fencing may tilt or deform, increasing safety hazards for electrical equipment. While reinforcement measures can mitigate this, they typically increase costs and installation complexity. Utility Model Content

This fixing method provides a stable anchor point during the tension adjustment process of the steel rope 211, ensuring that the steel rope will not affect the accuracy of the adjustment due to movement when adjusting the tension of the metal mesh 3. At the same time, since the second hook 212 is directly fixed to the base plate 104, the overall structural rigidity is enhanced, reducing the risk of structural instability caused by tension changes or external forces. Through this design, the second hook 212 not only ensures that the steel rope 211 can effectively transmit tension, but also improves the stability and safety of the entire safety fence system.

[0030] In this invention, the centerline of the first rotating shaft 203 is perpendicular to the centerline of the second rotating shaft 205 and lies in the same plane.

[0031] In this embodiment, the axis of the first rotating shaft 203 is perpendicular to the axis of the second rotating shaft 205 and lies in the same plane. This axis design allows the ring 204 to rotate in two mutually perpendicular directions, providing a multi-degree-of-freedom adjustment mechanism. Through the perpendicular relationship between the axis of the first rotating shaft 203 and the axis of the second rotating shaft 205, the ring 204 on the adjustment plate 201 can rotate freely in the horizontal and vertical planes. This design greatly enhances the angle adjustment flexibility of the safety fence during installation, enabling it to adapt to various complex terrains or equipment layout requirements. At the same time, since the two rotating shafts are located in the same plane, it ensures that the angle adjustment is simple and intuitive, effectively avoiding complex spatial positioning problems and improving the efficiency and accuracy of installation and adjustment. This structural design significantly improves the adaptability and ease of installation of the safety fence in practical applications by providing multi-dimensional adjustment capabilities.
