AI Technical Summary
Existing fixed nails are prone to move outwards under the force of soil on the outward movement of the barbed wire mesh, resulting in loosening of the barbed wire mesh and poor slope protection effect.
The water conservancy slope protection net fixing nails with an outer cylinder structure are pushed out of the inside of the outer cylinder by tapping the rod, and the barbs are pierced into the soil, forming a stable fixed structure to prevent the fixing nails from moving outward.
The fixing effect of the slope protection net is improved, ensuring that the barbed wire mesh is firmly fixed to the ground, and enhancing the stability of the slope protection net.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a fixing nail for a water conservancy slope protection net and a water conservancy slope protection net. Background Technique
[0002] Dams are common water conservancy project buildings. In order to maintain the stability of the dam slope, a dam slope protection net can be used. The protection net generally uses a wire mesh, and plants such as turf can also be planted in the net to consolidate the soil. There is also a method of spraying mortar on the wire mesh for slope protection. The protection net is fixed to the slope ground through fixing nails.
[0003] Existing fixing nails generally use ordinary iron nails, or barbs are provided on the iron nails. However, due to the outward force of the soil on the wire mesh, the fixing nails move outward, resulting in the loosening of the wire mesh and poor slope protection effect; when the iron nails with barbs are driven into the soil, the barbs will also squeeze the soil to form a channel for the barbs to enter. Therefore, under the outward force of the soil on the wire mesh, the barbs will not play a role in restricting the loosening of the iron nails.
[0004] In summary, when the fixing nails for fixing the slope protection net are pushed by the outward force of the soil on the wire mesh, the fixing nails move outward, resulting in the loosening of the wire mesh and poor slope protection effect. Content of the Utility Model
[0005] Aiming at the technical problems existing in the prior art, the purpose of the utility model is: to provide a fixing nail for a water conservancy slope protection net, which solves the problem that the fixing nail moves outward under the action of the outward force of the soil on the wire mesh, resulting in the loosening of the wire mesh.

[0020] The present utility model will be further described in detail below in conjunction with the specific embodiments.
[0021] Embodiment 1
[0022] As Figures 1-3 shown, a water conservancy slope protection net fixing nail provided in this embodiment includes: an outer cylinder, an opening 21 and a movable opening 22 are provided at the top of the outer cylinder, the inside of the outer cylinder is a hollow structure, the opening 21 is communicated with the inside of the outer cylinder, and the movable opening 22 is communicated with the inside of the outer cylinder; a knocking rod 1, the knocking rod 1 can be inserted into the inside of the outer cylinder from the opening 21 and push the barb 4 out of the outside of the outer cylinder through the movable opening 22; the barb 4, the barb 4 is hinged to the inside of the outer cylinder, and the barb 4 can extend out of the outside of the outer cylinder through the movable opening 22 from the inside of the outer cylinder.
[0023] The outer cylinder includes a cylinder body 2 and a nail head 3, the cylinder body 2 and the nail head 3 are threadedly connected, the opening 21 and the movable opening 22 are both located in the cylinder body 2, and the barb 4 is hinged to the nail head 3. Specifically, an internal thread is provided at the position where the cylinder body 2 and the nail head 3 are connected, and an external thread is provided to the nail head 3, and the two are connected and fixed by thread cooperation, the barb 4 and the nail head 3 are hinged by a rotating shaft, the rotating shaft is rotatably connected to the nail head 3, and the barb 4 is fixed on the rotating shaft.
[0024] In some embodiments, the outer cylinder includes a cylinder body 2 and a nail head 3, the cylinder body 2 is provided with a socket, and the nail head is provided with a connecting hole. When the cylinder body and the nail head are docked, the socket and the connecting hole are connected, and the socket and the connecting hole are connected by a pin; the opening and the movable opening are both located in the cylinder body, and the barb is hinged to the nail head.
[0025] There are multiple active openings 22 , which are evenly distributed along the circumference of the outer tube. The number of barbs 4 is consistent with the number of active openings 22 , and the multiple barbs 4 correspond to the multiple active openings 22 one by one.
