Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a new type of dense mesh which can be automatically opened when encountering wind. Background Art

[0002] With the acceleration of urban construction and industrial development, the safety protection of aerial work has become a crucial link. Among them, the dense mesh safety vertical net is widely used in various scaffolding projects due to its good anti-fall and isolation effects. However, in the actual application process, especially in coastal areas or in strong wind environments, the traditional dense mesh net faces a significant problem: when the wind is strong, the safety net is easily blown up, torn or even blown off as a whole, which not only affects the construction safety, but also may cause environmental pollution, and also increase the subsequent maintenance costs. In traditional construction, in order to cope with the impact of wind on the dense mesh net, methods such as increasing the density of fixed points and using heavier mesh materials are usually adopted, but these measures are often only temporary solutions and fail to fundamentally solve the challenge of wind pressure to the stability of the net body, and also sacrifice a certain degree of aesthetics and economy. For example, although adding fixed points can improve stability, it also makes the construction process more cumbersome, and too many fixings may damage the base structure; although the use of heavy materials can enhance wind resistance, it increases the difficulty of installation and transportation costs. Therefore, the market is in urgent need of a new type of dense mesh that can not only ensure safety protection effectiveness, but also effectively resist strong winds, while taking into account economy, aesthetics and easy maintenance.

[0023] refer to Figure 1 and Figure 2, the present embodiment provides a new type of dense mesh net that can be opened automatically when encountering wind, and the new type of dense mesh net includes a movable dense mesh net 1 and a fixed dense mesh net 6, wherein the movable dense mesh net 1 and the fixed dense mesh net 6 are fixedly connected. Specifically, a fixed frame 4 is provided inside the fixed dense mesh net 6, and the movable dense mesh net 1 is arranged inside the fixed frame 4, and the upper end of the movable dense mesh net 1 and the lower end of the fixed dense mesh net 6 are integrally connected. Further, a connecting rod 7 is provided at the lower end of the movable dense mesh net 1, and the lower end of the movable dense mesh net 1 is fixedly connected to the connecting rod 7, and the connecting rod 7 and the lower end of the fixed frame 4 are fixedly connected through an adjustment component 2, and the adjustment component 2 is arranged inside the fixed frame 4. It is worth noting that the four ends of the fixed dense mesh net 6 are provided with connecting iron rings 5, and the outer surface of each connecting iron ring 5 is sleeved with a nylon sleeve 3, and the durability of the dense mesh net can be improved by wrapping the connecting iron ring 5 with the nylon sleeve 3. At the same time, the two adjacent dense mesh nets can be connected by passing the iron wire through the connecting iron ring 5 on the two adjacent dense mesh nets.

[0024] In this embodiment, the adjustment assembly 2 includes a middle fixed block 9, a lower connecting block 11 and an upper connecting block 14. The upper connecting block 14, the middle fixed block 9 and the lower connecting block 11 are arranged in sequence from top to bottom, and the upper connecting block 14, the middle fixed block 9 and the lower connecting block 11 are connected by a reset spring 10. At the same time, the upper connecting block 14 is connected to the connecting rod 7, and the lower connecting block 11 is connected to the lower end of the fixed frame 4. Further, a positioning block 13 is arranged at the upper end of the middle fixed block 9. The upper L-shaped connecting rod 8 and the lower L-shaped connecting rod 15 are arranged on opposite sides of the positioning block 13, specifically, the upper L-shaped connecting rod 8 is connected to the connecting rod 7, and the lower L-shaped connecting rod 15 is connected to the lower end of the fixed frame 4. That is to say, the upper end of the upper L-shaped connecting rod 8 and the upper connecting block 14 are located on the same horizontal line, and the lower end of the lower L-shaped connecting rod 15 and the lower connecting block 11 are located on the same horizontal line. Furthermore, the upper end of the middle fixed block 9 and the lower end of the upper L-shaped connecting rod 8 are connected by a movable connecting rod 12, and the end of the middle fixed block 9 and the inner side of the lower L-shaped connecting rod 15 are connected by the movable connecting rod 12, wherein the lower end of the upper L-shaped connecting rod 8 and the inner side of the lower L-shaped connecting rod 15 are both provided with a slide groove, and the inside of the slide groove is connected to the end of the movable connecting rod 12. In other words, the movable connecting rod 12 can slide on the slide groove.

[0025] Furthermore, the new dense mesh in this embodiment is used during the process, including initial installation, response under wind force and reset after the wind stops, and the specific process is as follows:

[0026] First, install the fixed dense mesh 6 according to the engineering requirements, and ensure that it is firmly connected to the external support structure through the connecting iron ring 5 on all sides, and then place the movable dense mesh 1 inside the fixed frame 4, and the upper end is integrally connected to the fixed dense mesh 6. Then install the adjustment component 2, that is, the upper L-shaped connecting rod 8 is connected to the connecting rod 7, and the lower L-shaped connecting rod 15 is connected to the lower end of the fixed frame 4. Then set the preload force of the reset spring 10, that is, pre-set the initial tension state of the movable dense mesh 1. When adjusting, the distance between the upper connecting block 14 and the lower connecting block 11 can be adjusted to control the compression degree of the reset spring 10 to adapt to different wind conditions.

[0027] Furthermore, when encountering wind, the wind pressure acts on the movable dense mesh 1. Due to the presence of the reset spring 10, the movable dense mesh 1 can be opened upward, thereby increasing the contact area between the mesh surface and the wind, and then dispersing the wind force to prevent the mesh surface from being subjected to excessive impact. At the same time, the middle fixed block 9 and the upper L-shaped connecting rod 8 and the lower L-shaped connecting rod 15 connected thereto, in conjunction with the sliding of the movable connecting rod 12 in the slide groove, can enable the entire adjustment component 2 to flexibly adapt to wind force changes and achieve dynamic balance.

[0028] Furthermore, as the wind weakens or disappears, the reset spring 10 will begin to release the stored energy, that is, push the movable dense mesh 1 downward to reset until it returns to or approaches the initial setting position. It is worth noting that the smooth sliding of the movable connecting rod 12 in the slide groove can further ensure the smoothness of the reset process, thereby reducing the impact on the entire structure, thereby improving the stability and durability of the entire system.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
