Therefore, no matter the fence system disclosed in CN101892767B or the mesh 10 of the present invention, the existing steel bar shears and pliers cannot be directly inserted into the mesh 10 to shear and damage the mesh 10, so that the steel bar shears and pliers need to be transversely inserted into the mesh 10 to be used as a picking tool or to be used by matching a prying bar with the steel bar shears and pliers alone, and the steel bar shears and pliers with a blade thickness of 6mm are enough to be inserted into the mesh 10 disclosed in CN101892767B and the mesh 10 of the present invention to pry, so that when the mesh 10 is pried enough to be inserted into the steel bar shears and pliers, the mesh 10 is damaged by the steel bar and pliers to achieve the time required for the invasion, the invasion table 1 is 8-inch steel bar shears and pliers to damage the mesh 10 disclosed in CN101892767B to achieve the time required for the invasion, the invasion table 2 is 8-inch steel bar shears and pliers to damage the mesh 10 of the present invention to achieve the time required for the invasion, this required time is the actual destruction time, excluding the test preparation time and the time delayed in the test process:

TABLE 1

TABLE 2

Note that the above-mentioned 600cm²Are close values and not exact values.

In the test process, the distance between the longitudinal second direction rib 12 in the utility model and the prior art (CN101892767B) is relatively large, so that the longitudinal second direction rib is not suitable for prying, and therefore only can be pried up and down, and, among them, it is found that the distance between the first direction beads 11 in the lateral direction of the present invention is shorter than the distance between the first direction beads 11 in the prior art, therefore, in the prying operation in the test, the degree of deformation of the prying first direction rib 11 of the present invention is found to be larger than that of the prior art, after the first prying, the deformed first-direction rib 11 is found to be closer to the other-direction rib than the prior art, so that the difficulty of the second prying is increased, the steel bar shears and the pliers are more difficult to extend into the mesh 10, the web 10 of the present invention is believed to be superior in protective performance and effectiveness to the prior art because it is extremely cumbersome to cut and requires more time to break.

Second, when the first direction rib 11 and the second direction rib 12 of the present invention and the related art (CN101892767B) are aligned in a space of 1000 × 100mm, it is found that:

the first direction ribs 11 of the present invention may be arranged: 100/12.6 ≈ 7.9

The second direction ribs 12 of the present invention may be arranged: 1000/110 ≈ 9 roots

The prior art first direction ribs 11 may be arranged: 100/15 ≈ 6.6

The prior art second direction ribs 12 may be arranged: 1000/75.5 ≈ 13.2

From the above analysis, the present invention only needs to arrange 16.9 direction ribs in the space to achieve the protection purpose. The prior art needs to arrange 18.8 direction ribs to achieve the purpose of protection. Thus, the present invention will certainly result in a lighter overall mesh 10, lower cost, and better safety performance.

Thirdly, the first direction ribs 11 are transversely arranged, and the second direction ribs 12 are longitudinally arranged, so that the formed grid is transversely long, which is beneficial for patrols and cameras or detection equipment to observe and warn foreign people for the following reasons:

on the one hand, according to psychologist's research, people's sight observation range is flat and is sectorial, when being horizontal setting and when being vertical setting in the face of first direction muscle, the discovery is in the face of the first direction muscle of horizontal setting, its horizontal visible range is great, the permeability is strong, observe for a long time and be difficult for taking place dizzy, nevertheless when the discovery is in the face of the first direction muscle of vertical setting, its horizontal visible range is narrow little, the permeability is poor in the vision, observe for a long time and easily take place dizzy, be unfavorable for patrol personnel and make a video recording or detection equipment observe the early warning to the foreigner.

Therefore, the prevention of the safety is improved by the transversely arranged first direction rib.

On the other hand, the distance (75.5mm) between the second direction ribs arranged in the prior art (CN101892767B) is smaller than the distance (110mm) between the second direction ribs arranged in the utility model, the distance between two eyes of a person is generally 70mm-80mm, and the sight line observation range is fan-shaped, when observing outside people, the first direction ribs transversely arranged are found to have little interference on the sight line, and the second direction ribs longitudinally arranged can interfere the sight line of the person to a certain extent, so that the arrangement of the second direction ribs with wider width is beneficial to improving the safety precaution.

Fourthly, the distance of the first gap a is less than or equal to 12.6mm, the thicknesses of the index finger, the middle finger and the ring finger of the fingers of a part of adults are not more than 12.6mm, and the toes of most adults are not more than 12.6mm generally, so that the climbing and crossing of foreign people can be effectively prevented, the invasion of the foreign people can be effectively resisted, and the safety performance is improved.

Fifth, the mesh sheet 10 disclosed in the prior art (CN101892767B) has a portion bent outward to form a convex portion for tensioning the mesh sheet 10, and although the bent convex portion enhances the strength and the aesthetic appearance of the mesh sheet 10, it also provides an impetus for the climbing of the foreign person, so that the foreign person is more likely to enter the mesh sheet, which is more disadvantageous, but the mesh sheet 10 of the present invention is planar, and this is prevented, so that it is advantageous to improve the safety of the mesh sheet 10.

The distance between the first gaps a of two adjacent first-direction ribs 11 in the mesh 10 is limited to be less than or equal to 12.6mm, and the distance between the second gaps b of two adjacent second-direction ribs 12 is limited to be less than or equal to 110 mm. The time required by artificial damage is greatly prolonged, the safety performance is improved, and on the basis, the weight is reduced and the cost is reduced by less materials in the same protection range compared with the prior art, so that the better damage resistance is achieved. In addition, through the first direction muscle that transversely sets up and the second direction muscle that vertically sets up, can also improve the permeability of observing, and then improve the security of prevention invasion, consequently, effectively solve among the prior art the destruction prevention and the not ideal problem of lightweight effect of net piece 10.

In addition, in a special occasion, the mesh 10 is usually exposed to collision and possible explosion during protection, and in order to test the safety protection performance of the utility model in this respect, the utility model fixes the mesh 10 and the upright column by mounting, and then piles stones on the flat car, so that the flat car collides with the mesh 10 at an acceleration to a proper speed to obtain the anti-collision and anti-stone-crossing data.

Firstly, a test field adopts a flat compacted ground with a transverse gradient not more than 2.5 percent, and the compacted ground has no accumulated water, accumulated snow and ice.

Secondly, the flat plate trolley carrying stone block is about 500kg, the diameter of a tire is more than or equal to 300mm, the distance between a front wheel axle and a rear wheel axle is more than or equal to 2500mm, and a bumper for dealing with impact is arranged in front of the trolley.

The diameter of the stone block then takes the range 5-50 mm.

Finally, the trolley is pulled or pushed to accelerate to a speed corresponding to the impact kinetic energy, the impact kinetic energy is 15 jacks or more, and the pulling or pushing force is removed before the trolley impacts the mesh 10.

After the experiment, compared with the mesh 10 of the prior art (CN101892767B), the mesh 10 of the present application has less deformation degree at the joint of the mesh 10 of the present application and the upright post compared with the prior art, and in the frontal collision of the mesh 10, the mesh 10 of the present application has bending and a small amount of cracks at the impact position, while the second direction ribs distributed at the impact position of the mesh 10 of the prior art are more than the present application, but the second direction ribs are less, therefore, the bending degree and the amount of cracks of the mesh 10 of the prior art are obviously more, so the mesh 10 of the present application is stronger than the prior art in the aspect of impact prevention, and the safety performance is stronger.

Further, by collecting different diameter rocks that fly from the car and pass through the mesh 10 after passing this test, compared to the total, the protection of the present and prior art meshes 10 against spattering debris as shown in tables 3, 4 below is obtained:

TABLE 3

Stone diameter (mm)	Mesh passage rate in the prior art
		5	84.5％
8.5	71.32％
		15.75	60.36％
23.35	33.328％
		32.3	7％
42.1	0％
		50	0％

TABLE 4

Stone diameter (mm)	Mesh sheet passing rate of the present application
		5	79.98％
8.5	64.76％
		15.75	33.33％
23.35	6％
		32.3	0％
42.1	0％
		50	0％

The stone diameters described in tables 3 and 4 above are approximate or average, not absolute.

From the above analysis, in the process of simulating the explosion to generate fragments, the present invention finds that the protection capability of the mesh sheet 10 in the prior art against fragments flying is not high, and particularly when the mesh sheet 10 in the prior art protects fragments of about 15mm, the protection performance of the mesh sheet 10 in the prior art against fragments splashing is far lower than that in the present application, and therefore, the safety of the mesh sheet 10 in the present application is better than that in the prior art.
