[0022] 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.

[0023] Example

[0024] Please see Figures 1 to 5 The present invention provides a technical solution: a manhole safety net, including a fixing ring 1, a safety net body 2 is provided inside the fixing ring 1, the safety net body 2 is a honeycomb mesh structure, a connecting ring 3 is provided on the outer surface of the fixing ring 1, a connecting plate 4 is provided on the upper side of the connecting ring 3, and a limiting cross plate 5 is provided on the side of the connecting plate 4 away from the connecting ring 3.

[0025] Specifically, by setting the main body 2 of the fall arrest net to a honeycomb mesh structure, the honeycomb structure is composed of tightly arranged hexagonal units. This geometry can form the largest space with the least amount of material, and the force on each side is evenly distributed. At the same time, the porous nature of the honeycomb structure allows it to absorb energy through unit deformation when subjected to external force, reducing the force borne by a single point on the fall arrest net when heavy objects fall, and greatly improving the fall arrest net's load-bearing capacity.

[0026] Please see Figure 1-2 The fall protection net body 2 and the fixing ring 1 have several connection points, which are evenly distributed inside the fixing ring 1.

[0027] Specifically, the setting of multiple connection points improves the connection strength between the fall protection net body 2 and the fixing ring 1, thereby enhancing the overall integrity of the fall protection net.

[0028] Please see Figure 1-2 A connecting rib 6 is provided between the fixing ring 1 and the connecting plate 4. There are several connecting ribs 6, which are evenly distributed between the connecting ring 3 and the fixing ring 1.

[0029] Specifically, the multiple sets of connecting ribs 6 between the connecting ring 3 and the fixing ring 1 greatly reduce the overall weight of the fall protection net while improving the structural strength between the fixing ring 1 and the connecting plate 4.

[0030] Please see Figure 1 A reinforcing rib 7 is provided between the connecting ring 3, the connecting plate 4, and the limiting horizontal plate 5.

[0031] Specifically, the reinforcement rib 7 improves the connection strength between the connecting ring 3, the connecting plate 4, and the limiting cross plate 5.

[0032] Please see Figure 1 There are several connecting plates 4 and limiting cross plates 5, which are evenly distributed on the outer surface of the connecting ring 3, and there are three reinforcing ribs 7 at each connecting plate 4.

[0033] Specifically, the installation of multiple sets of connecting plates 4 and limiting horizontal plates 5 improves the stability of the fall protection net.

[0034] Please see Figure 1 The limiting horizontal plate 5 has a cavity structure, and a fixing connecting plate 8 is provided on the inner wall of the cavity of the limiting horizontal plate 5.

[0035] Specifically, the cavity structure limiting plate 5 reduces the overall mass of the fall protection net, while the fixed connecting plate 8 improves the structural strength of the limiting plate 5.

[0036] In use, the fall arrestor net is installed at the corresponding well edge via the limiting horizontal plate 5 and the connecting plate 4. The fall arrestor net body 2 features a honeycomb mesh structure, composed of tightly arranged hexagonal units. This geometry allows for the creation of the largest space with minimal material, and the stress is evenly distributed on each side. Furthermore, the porous nature of the honeycomb structure enables it to absorb energy through unit deformation when subjected to external forces, reducing the force borne by a single point on the fall arrestor net when a heavy object falls, thus greatly improving its load-bearing capacity. Multiple sets of connecting ribs 6 connect the connecting ring 3 and the fixing ring 1. While improving the structural strength between the fixing ring 1 and the connecting plate 4, the overall mass of the fall protection net is greatly reduced. By setting the reinforcing rib 7, the connection strength between the connecting ring 3, the connecting plate 4 and the limiting horizontal plate 5 is improved. The setting of the limiting horizontal plate 5 with a cavity structure reduces the overall mass of the fall protection net. The setting of the fixing connecting plate 8 improves the structural strength of the limiting horizontal plate 5. Thus, this kind of manhole fall protection net has the effect of maximizing material efficiency and strong impact and seismic performance, and it also has the effect of increasing the structural strength of the fall protection net while reducing its mass.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
