[0002] The dam slope protection net is a slope protection material used in water conservancy projects. It is often used to protect and strengthen soil and rock slopes such as dams and levees. It is usually made of wire mesh or plastic mesh and has high strength and corrosion resistance. The dam slope protection net is mainly used to prevent erosion and landslides on soil and rock slopes, and plays a role in enhancing the stability of the slope. It can fix the soil and rock particles on the slope and reduce the slope collapse caused by water scouring. At the same time, the slope protection net can also effectively prevent the erosion of fine soil particles, slow down the soil erosion rate, and protect the safe and stable operation of water conservancy projects.

[0044] After the connecting buckle fixes the buckle inner core 1 through the positioning pin 4, the buckle outer core is rotated 220°-30° in one direction, and the four L-shaped locking wings 10 are used to lock the slope protection nets at the same time. The buckle outer core 2 cannot be rotated reversely after rotation. Not only is the operation simple and quick, but the stability after the fixed connection is also ensured.

[0045] like Figure 3 As shown, the pin head of the elastic latch pin 7 is a round head.

[0046] In order to reduce the wear between the pin head of the elastic latch pin 7 and the one-way ratchet gear 9, the pin head of the elastic latch pin 7 is designed to be a round head to reduce its friction force, thereby extending its service life.

[0047] like Figure 1 , Figure 3 As shown, a sealing cover 11 is installed above the cavity 5 by means of threaded engagement; wherein, the upper surface of the sealing cover 11 is provided with four rotating grooves 12 distributed in a circumferential array.

[0048] In order to achieve sealing of the cavity 5 , a detachable sealing cover 11 is provided, and a rotation groove 12 is provided to facilitate installation or removal of the sealing cover 11 .

[0049] like Figures 2 to 3 As shown, the upper and lower surfaces of the L-shaped locking wing 10 are both provided with anti-slip portions.

[0059] When installing the connecting buckle, the four L-shaped locking wings 10 are respectively placed in the installation grooves 16 of the four adjacent slope protection nets. Then, the positioning pin 4 is knocked in so that the positioning pin 4 is embedded in the dam body to complete the fixation of the buckle inner core 1; after that, the buckle outer core 2 is rotated clockwise by 20°-30°, and the four L-shaped locking wings 10 can be completely inserted into the installation slots 17. Due to the design of the elastic pin 7 and the one-way ratchet gear 9, the buckle outer core 2 cannot be reversed after clockwise rotation. Not only is the operation simple and quick, but it also ensures the stability after fixed connection.

[0060] In order to release the installation of the connecting buckle, the sealing cover 11 can be removed. At this time, the elastic pin 7 is exposed in the inner cavity. By stretching the elastic pin 7, the spring 8 can be compressed to release the interference between the elastic pin 7 and the two adjacent ratchet teeth on the one-way ratchet gear 9. At this time, the buckle outer core 2 can rotate in the opposite direction to release the installation of the connecting buckle.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
