[0027] Example 1 will be described in conjunction with Figure 1 as follows:

[0028] An earthquake-resistant and wind-proof green environmental protection fence for construction projects includes: a fence installation frame 1, a wind-proof net assembly 2, a counterweight 3, an earthquake-resistant arch beam 4, and a support plate 5. The wind-proof net assembly 2 is arranged on the fence installation frame 1, and the fence installation frame 1 is fixedly connected to the wall. The counterweight 3 is arranged at the bottom of the fence installation frame 1, the earthquake-resistant arch beam 4 is fixedly installed on the lower side of the counterweight 3, the support plate 5 is arranged on the lower side of the earthquake-resistant arch beam 4, and the support plate 5 is fixedly connected to the wall.

[0029] By setting the counterweight 3, the earthquake-resistant arch beam 4, and the support plate 5 to form a "tumbler" structure, when the device is tilted under the action of an external force, its center of gravity will shift accordingly. Due to the shift of the center of gravity, the earthquake-resistant arch beam 4 will generate a resistance moment, which will prompt the device to return to its original equilibrium position, thereby improving the earthquake resistance performance and avoiding the use of support rods. By setting the wind-proof net assembly 2, the wind-proof performance is improved.

[0030] Example 2 will be described on the basis of Example 1 in conjunction with Figure 2 as follows:

[0031] The fence installation frame 1 includes: a left vertical rod 11, a right vertical rod 12, an upper cross beam 13, and a lower cross beam 14. The upper cross beam 13 and the lower cross beam 14 are arranged between the left vertical rod 11 and the right vertical rod 12 and are fixedly connected to the left vertical rod 11 and the right vertical rod 12. The left vertical rod 11 and the right vertical rod 12 are fixedly connected to the wall. The wind-proof net assembly 2 is arranged within the area surrounded by the left vertical rod 11, the right vertical rod 12, the upper cross beam 13, and the lower cross beam 14. The counterweight 3 is arranged on the lower side of the lower cross beam 14 and is fixedly connected to the left vertical rod 11 and the right vertical rod 12.

[0032] Through the fixed connection of the left vertical rod 11, the right vertical rod 12, the upper cross beam 13, and the lower cross beam 14, a strong frame structure is formed, which can improve the stability of the entire fence system and enable it to better resist external forces such as wind pressure or other impacts. The wind-proof net assembly 2 is arranged within the area surrounded by the vertical rods and the cross beams, which can effectively block strong winds, reduce the impact of wind on the building, and improve the safety of the building.

[0033] Example 3 will be described on the basis of Example 2 in conjunction with Figure 3 as follows:

[0034] The windbreak net assembly 2 includes: a windbreak net plate 21 and a reinforcing cross rib 22. The outer sides of the windbreak net plate 21 are respectively fixedly connected to the left vertical pole 11, the right vertical pole 12, the upper cross beam 13 and the lower cross beam 14. The reinforcing cross rib 22 is fixedly installed on the windbreak net plate 21, and the end parts of the reinforcing cross rib 22 are respectively fixedly connected to the left vertical pole 11, the right vertical pole 12 and the upper cross beam 13. Multiple groups of air inlet mesh holes are evenly arranged on the windbreak net plate 21.

[0035] The windbreak net plate 21 is fixedly connected to the vertical poles and cross beams of the guardrail, forming a closed windbreak surface, which can effectively reduce the impact of strong winds on the building and protect the safety of the building structure. The setting of the reinforcing cross rib 22 increases the stiffness and strength of the windbreak net plate 21, enabling the windbreak net assembly 2 to better maintain its shape and stability when subjected to wind pressure or other external forces, and it is not easily deformed or damaged. The design of multiple groups of air inlet mesh holes allows the wind to pass through, which can reduce the impact force of the wind on the windbreak net plate, evenly disperse the wind force at the same time, reduce the local pressure, and thus improve the windbreak performance of the entire guardrail.

[0036] Example 4, based on Example 3, is described in combination with Figure 4 as follows:

[0037] The counterweight block 3 is made of lead or lead-antimony alloy or iron-nickel alloy. Lead, lead-antimony alloy and iron-nickel alloy all have relatively high densities, which means that they can provide greater weights under the same volume, thereby enhancing the stability of the guardrail system and improving its earthquake resistance and wind resistance. Due to the high density, the counterweight block can be smaller, which is beneficial for use in cases where space is limited.

[0038] The cross-section of the seismic arch beam 4 is semi-circular, the lower part of the seismic arch beam 4 is an arc surface, and the lowest point of the lower surface of the seismic arch beam 4 is arranged in fit with the upper surface of the support plate 5. The semi-circular cross-section and the arc surface design of the lower part enable the seismic arch beam to better withstand and disperse external forces.

[0039] Example 5, based on Example 4, is described in combination with Figure 5 as follows:

[0040] The device further includes: a green plant rack 6. The green plant rack 6 is fixedly installed on the upper part of the guardrail installation rack 1, and the green plant rack 6 is provided with water leakage holes. The green plant rack 6 is fixedly installed on the upper part of the guardrail installation rack 1 and can be used to place green plants, which not only beautifies the appearance of the building, but also improves the urban greening level and environmental quality. The water leakage holes can ensure the smooth discharge of excess water on the green plant rack, avoid water accumulation from damaging the green plants, and the water leakage holes also help to maintain the air permeability of the soil in the green plant rack, which is beneficial to the respiration and growth of plant roots.

[0041] Example 6, based on Example 5, is described in combination with Figure 6 as follows:

[0042] The device further includes: a guard plate 7, which is fixedly installed inside the guardrail mounting frame 1. An empty area for the ventilation path of the windproof net assembly 2 is provided on the guard plate 7, and the lower surface of the guard plate 7 is in contact with the ground. The design of the guard plate 7 can be coordinated with the appearance style of the building, enhancing the aesthetics of the building. At the same time, it hides the internal structure, making the whole more tidy. An empty area for the ventilation path of the windproof net assembly 2 is provided on the guard plate 7, which can keep the air flowing, reduce the negative impact of wind pressure on the guardrail, and avoid reducing the effect of the windproof net assembly due to poor ventilation.

[0043] The working principle of the present utility model: During use, first fix the left vertical rod 11, the right vertical rod 12, the upper cross beam 13, and the lower cross beam 14 to the wall. Subsequently, install the windproof net plate 21 within the enclosed area formed by the left vertical rod 11, the right vertical rod 12, the upper cross beam 13, and the lower cross beam 14. Then, fixedly connect the reinforcing cross ribs 22 to the windproof net plate 21, and further fixedly connect the reinforcing cross ribs 22 and the guardrail mounting frame 1 to ensure the strength of the windproof net plate 21. Subsequently, install the counterweight 3 on the lower side of the lower cross beam 14, and then install the seismic arch beam 4 on the lower side of the counterweight 3. Then, fixedly install the support plate 5 on the ground, making the upper surface of the support plate 5 in contact with the lowest point of the seismic arch beam 4. The present utility model forms a "tumbler" structure by setting the counterweight 3, the seismic arch beam 4, and the support plate 5. When the device is tilted under the action of an external force, its center of gravity will shift accordingly. Due to the shift of the center of gravity, the seismic arch beam will generate a resisting moment, which will prompt the device to return to its original equilibrium position, thereby improving the seismic performance.
