A clamping groove 7 is formed on the surface of the installation groove 6. An installation frame 8 is clamped inside the clamping groove 7, and the installation frame 8 is arranged in a clamping manner with the installation groove 6. A protection net 9 is fixedly connected to the inner wall of the installation frame 8. Positioning holes 10 are formed at the four corners of the surface of the installation frame 8. Four positioning columns 11 are fixedly connected to the inside of the installation groove 6, and the four positioning columns 11 correspond to and cooperate with the four positioning holes 10 one by one.

[0023] Reference Figure 4 , a positioning groove 12 is formed at the top of the positioning hole 10. An extrusion cavity 13 is formed on the surface of the positioning column 11. A spring 14 is fixedly connected to the inside of the extrusion cavity 13. Positioning strips 15 are symmetrically and fixedly connected to both sides of the spring 14, and the positioning strips 15 are clamped with the positioning groove 12.

[0024] As a technical optimization scheme of the utility model, through the settings of the positioning groove 12, the extrusion cavity 13, the spring 14 and the positioning strips 15, the movement track of the positioning column 11 can be positioned, so that the positioning effect of the installation frame 8 can be realized, and the problem that it falls off automatically during use can be avoided.

[0025] Reference Figure 4 , limiting grooves 16 are formed at the top and bottom of the extrusion cavity 13. A limiting block 17 is fixedly connected to one end of the positioning strip 15 close to the spring 14, and the limiting block 17 is slidably connected with the limiting groove 16.

[0026] As a technical optimization scheme of the utility model, through the settings of the limiting groove 16 and the limiting block 17, the maximum displacement track of the positioning strip 15 can be limited, and the problem that it is lost due to its separation from the extrusion cavity 13 can be prevented.

[0027] Reference Figure 4 , the length of the positioning groove 12 is greater than the maximum extension position of the positioning strip 15.

[0028] As a technical optimization scheme of the utility model, through the setting that the length of the positioning groove 12 is greater than the maximum extension position of the positioning strip 15, when the staff disassembles the installation frame 8, the positioning strip 15 can be extruded through the gap between the positioning groove 12 and the positioning strip 15, thereby improving the convenience during disassembly.

[0029] Reference Figure 1 and Figure 2, a plurality of reinforcing anchor bolts 18 are fixedly connected to the back surface of the protection plate 1, and the plurality of reinforcing anchor bolts 18 are arranged evenly.

[0030] As a technical optimization scheme of the present utility model, through the arrangement of the plurality of reinforcing anchor bolts 18, the positioning effect of the protection plate 1 can be further enhanced, so that it can be more firm during protection.

[0031] Reference Figure 1 and Figure 3 , a protection rib 19 is fixedly connected to the surface of the protection plate 1.

[0032] As a technical optimization scheme of the present utility model, through the arrangement of the protection rib 19, standing support points can be added to the surface of the protection plate 1, thereby preventing the installation frame 8 from being on an inclined plane when the staff maintains it, which is not conducive to the maintenance operation.

[0033] The working principle and usage process of the present utility model: When using this protection device to protect the slope of a water conservancy and hydropower project, first, the protection plate 1 can be installed on the slope through the reinforcing anchor bolts 18, and then the installation strip 4 is rotated to a suitable angle by the rotation of the rotating bar 2 and the rotating shaft 3, and it is positioned at the edge of the slope through the fixed anchor bolts 5, so that the protection plate 1 can be applicable to different terrains. Then, the slope is protected by the installation frame 8 and the protection net 9 in the installation groove 6 and the clamping groove 7. When it is necessary to replace the installation frame 8 in the clamping groove 7 due to damage, first find the position of the damaged installation frame 8 and move to this clamping groove 7, press the positioning strip 15 on the positioning column 11 at this position, so that it is retracted into the extrusion cavity 13. At this time, the two symmetrical positioning strips 15 compress the spring 14, and then press the other three positioning strips 15 at this position in turn to make them retract into the extrusion cavity 13, and then the installation frame 8 can be pulled out upward to complete the disassembly operation of the protection net 9. Then, align the new installation frame 8 and the protection net 9 with the installation groove 6 and the clamping groove 7 at this position for clamping. At this time, it is necessary to make the positioning hole 10 slide along the positioning column 11 until it cannot move, and then the positioning strip 15 is ejected outward by the reaction force of the spring 14, so that the positioning strip 15 can be clamped into the positioning groove 12, thereby being able to position the position of the installation frame 8, and further being able to achieve the effect of quickly installing it, so that the staff can replace and maintain the protection net 9 alone, which is convenient for the staff to use and reduces resource waste.
