Advantageous effects

Compared with the prior art, the wild animal protection isolation fence has the advantages that:

1. the lower section of the vertical rod is buried in the ground. When the wild animal collides the first hawser of protection isolated column, first hawser produces the pulling force, and this pulling force becomes the overdraft to the slide bar in the montant through the assembly pulley, and the slide bar pushes down and is ejecting from montant hypomere lateral wall with the nail through the inclined plane structure, and during convex nail pricked the soil, increased the frictional force between montant and the soil, made the montant more be difficult to extract. And when first hawser did not receive the pulling force, the nail can not follow the lateral wall protrusion of montant hypomere, makes things convenient for personnel to insert the montant in the soil, also makes things convenient for personnel to extract the montant from the soil, convenient operation.

2. The reset spring can reset the slide bar, and the nail is prevented from protruding out of the side wall of the lower section of the vertical rod when the first mooring rope is not pulled.

3. The nail is arranged from top to bottom along the montant hypomere, and the pulling force that receives when first hawser is big more, the slide bar is pressed lowly, and the height of inclined plane structure is also low more, and then the nail of being ejected is more, and the frictional force between montant and the ground is also big more, and the montant is difficult more pulled out.

4. Each nail is arranged around the central line of the vertical rod, and the friction force between the vertical rod and the ground is further increased when the nail protrudes.

5. Through the back taper structure of montant lower extreme, make things convenient for personnel to insert the montant ground.

6. The secondary cable does not cooperate with the nail, but increases the effective area and height of the protective barrier.

The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings, which illustrate embodiments of the invention.

Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings.

Examples

The specific implementation manner of the invention is as shown in fig. 1 to 4, and the wild animal protection isolation fence comprises at least two vertical rods 1 which are arranged at intervals, and further comprises a first cable 2, two ends of the first cable 2 respectively extend into inner cavities of two adjacent vertical rods 1, and a sliding rod 3 is slidably arranged in the inner cavity of each vertical rod 1. The lower section of the vertical rod 1 is provided with a nail 7 with one end capable of extending out of the side wall of the lower section of the vertical rod 1 in a transverse sliding way. The first cable 2 is linked with the upper end of the sliding rod 3 through a pulley block 4, and the lower end of the sliding rod 3 is linked with the nail 7 through an inclined surface structure 6.

In this embodiment, the pulley block 4 includes a movable pulley 41, a first fixed pulley 42, and a second fixed pulley 43. The first fixed pulley 42 and the second fixed pulley 43 are connected on the inner wall of the vertical rod 1, the movable pulley 41 is connected at the upper end of the sliding rod 3, and the sliding rod 3 is positioned between the first fixed pulley 42 and the second fixed pulley 43. The first rope 2 passes around the lower side of the first fixed sheave 42, the upper side of the movable sheave 41, and the lower side of the second fixed sheave 43 in this order. In this embodiment, after the two ends of the first rope 2 respectively wind around the first fixed pulley 42 and the second fixed pulley 43, the two ends of the first rope also respectively penetrate through the two side walls of the vertical rod 1, and one first rope 2 can sequentially penetrate through the plurality of vertical rods 1. In addition, after one end of the first cable 2 in the vertical rod 1 is wound around the first fixed pulley 42 or the second fixed pulley 43, the first cable can also be directly and fixedly connected with the inner wall of the vertical rod 1, and the other end of the first cable 2 extends out of the vertical rod 1.

The inclined plane structure 6 is connected to the lower end of the slide rod 3, and an inclined plane 61 is arranged on the side wall of the inclined plane structure 6. A return spring 8 is connected between the inclined plane structure 6 and the inner wall of the vertical rod 1, and the return spring 8 is vertically arranged. The number of the return springs 8 is at least two and is arranged around the central line of the vertical rod 1.

The number of the nails 7 is at least two and is arranged up and down along the lower section of the vertical rod 1. In this embodiment, the nails 7 are arranged in three layers from top to bottom. At least two nails 7 are arranged on the vertical rod 1 at the same height, and each nail 7 is arranged around the central line of the vertical rod 1. The inner wall of the vertical rod 1 is provided with a guide rail 11 which is horizontally arranged, and the side wall of the nail 7 is in sliding fit with the guide rail 11.

The rear end of the nail 7 is provided with a roller 71, and the roller 71 corresponds to the inclined surface 61 of the inclined surface structure 6. When the two contact each other, the roller 71 rolls on the inclined surface 61 along with the up-and-down movement of the inclined surface 61, thereby avoiding sliding friction, reducing resistance and reducing abrasion.

A guide groove 5 is arranged in the inner cavity of the vertical rod 1, and the slide rod 3 is in sliding fit with the guide groove 5. The lower extreme of montant 1 is equipped with back taper structure 12, makes things convenient for personnel to insert the montant ground. A plurality of second mooring ropes 10 are connected between two adjacent vertical rods 1. When the overall length of the wild animal protection isolation fence is longer, a plurality of first mooring ropes 2 can be adopted, and the adjacent first mooring ropes 2 are connected with each other through connectors 9. The connector 9 may adopt a screw coupling structure.

When the safety fence is used, wild animal protection isolation fences are arranged according to the range of an isolation area, personnel insert the lower sections of the vertical rods 1 into the ground, and unfold the first mooring ropes 2 and the second mooring ropes 10. When the first cable 2 is not under tension, the nail 7 will not extend out from the side wall of the lower section of the vertical bar 1. When the wild animal collides with the first mooring rope 2, the first mooring rope 2 is subjected to pulling force, the pulling force becomes downward force to the sliding rod 3 in the vertical rod 1 through the pulley block 4, the sliding rod 3 moves downward and ejects the nail 7 out of the side wall of the lower section of the vertical rod 1 through the inclined surface structure 6, and the convex nail 7 is pricked into the ground, so that the friction force between the vertical rod 1 and the ground is increased, and the vertical rod 1 is more difficult to pull out due to the collision of the wild animal. The greater the pulling force on the first cable 2, the greater the distance the ramp structure 6 moves down, the more nails 7 are ejected and the greater the friction between the vertical bar 1 and the ground.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made in accordance with the spirit of the present invention.
