Technical Field

[0001] The utility model relates to the technical field of slope protection nets, in particular to a slope protection net for a water conservancy dam slope. Background Art

[0002] The slope protection net covers the surface of the slope of the water conservancy project, which can effectively protect the soil from erosion by water flow, wind erosion and other factors, and prolong the service life of the soil. At the same time, the slope protection net can also increase the anti-slip stability of the slope, prevent the soil from landslides, and ensure the safe operation of the water conservancy project. The slope protection net of the water conservancy dam slope is usually made of metal wire, plastic wire or composite material. Its structure mainly includes the slope protection net itself, connectors and support bodies. The slope protection net itself is usually in the form of a grid or mesh belt, with certain flexibility and tensile strength. The connectors are used to connect the various parts of the slope protection net to enhance the overall stability, and the support body is used to fix the slope protection net to prevent it from shifting or loosening during use;

[0003] After searching, a Chinese patent discloses a water-utilizing slope protection net (authorization announcement number CN220150219U), including a slope protection net mounting frame, the interior of the slope protection net mounting frame is detachably connected to a slope protection net replacement frame, the interior of the slope protection net replacement frame is provided with a slope protection net body, and a connecting mechanism is symmetrically provided on one side of the inner wall of the slope protection net mounting frame, the connecting mechanism includes a disassembly groove, the interior of the disassembly groove is fixedly connected to a limiting rod, the exterior of the limiting rod extends to the exterior of the slope protection net mounting frame and is slidably connected to a collar, and when splicing the slope protection net, first unscrew the second nut on the exterior of the first threaded rod on another slope protection net mounting frame above, and then move the collar to make the collar slide on the limiting rod while squeezing the spring to deform the spring, and then install the collar corresponding to the other slope protection net above The position of the frame is adjusted, the ring is loosened, and the ring can be rebounded under the rebound force of the spring, so that the ring is put on the first threaded rod, and then the second nut is re-tightened to the first threaded rod to complete the splicing. However, in this technical solution, the first threaded rod, the ring, and the second nut mainly provide the left and right side edges of the two adjacent slope protection net mounting frames to be limited and connected in the Z-axis direction, which means that the stability of the connection in the Z-axis direction is enhanced, but the stability in other directions will be affected, especially under complex terrain conditions of the slope, the movement of the soil is affected by multiple directions, and a single connection direction may be difficult to meet the multi-directional support required for soil stability, which will cause local stress concentration at the side connection of the slope protection net, increasing the risk of damage and destruction of the connection.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a slope protection net for a water conservancy dam slope, comprising a round-shaped protection frame 1 and a side frame 5 integrally formed on the outer wall of one side of the round-shaped protection frame 1, a slope protection net body 101 is installed inside the round-shaped protection frame 1, both ends of the surface of the side frame 5 are provided with positioning holes 6, two symmetrical protruding tongues 3 are integrally formed on the outer wall of the other side of the round-shaped protection frame 1, and a limiting column 4 for plugging with the positioning hole 6 is installed on the back of the protruding tongue 3, and the side portions between adjacent round-shaped protection frames 1 are limited in the Y-axis direction by the limiting column 4 and the positioning hole 6;

[0020] A hexagonal through hole 401 is provided on the outer wall of the limiting column 4, and hexagonal positioning bolts 9 are elastically installed at both ends of the inner side frame 5. The hexagonal positioning bolts 9 and the hexagonal through holes 401 are concentrically plugged, and the hexagonal positioning bolts 9 and the hexagonal through holes 401 are used to limit the side portions between adjacent circular protective frames 1 in the Z-axis direction;

[0021] Positioning feet 2 are fixed at the corners inside the circular protection frame 1. Through holes are arranged on the surface of the positioning feet 2. The dam slope protection net is fixed on the slope by the cooperation of the positioning feet 2 and the thread.

[0022] A cavity 501 is provided at one end of the inner part of the side frame 5, and an elastic positioning structure 10 is installed inside the cavity 501. The elastic positioning structure 10 is used to force the hexagonal positioning bolt 9 to move toward the center point of the positioning hole 6. A rectangular slide groove 7 is provided at one end of the surface of the side frame 5. A short shaft is slidably installed inside the rectangular slide groove 7. One end of the short shaft is fixedly connected to the surface of the hexagonal positioning bolt 9, and a sliding button 8 is fixed to the other end of the short shaft.

[0023] The staff manually slides the sliding button 8, so that the sliding button 8 drives the hexagonal positioning bolt 9 to slide toward the inside of the cavity 501, so that the hexagonal positioning bolt 9 no longer blocks the positioning hole 6. At this time, the limit column 4 and the positioning hole 6 can be smoothly plugged in;

[0024] The circular protection frame 1 is made of a hard plastic material, and the elastic positioning structure 10 is composed of a coil spring 1001 and a T-shaped cap 1002. The coil spring 1001 is fixed to the bottom of the cavity 501, and the T-shaped cap 1002 is fixed to the top of the coil spring 1001. The top of the T-shaped cap 1002 is fixedly connected to the bottom of the hexagonal positioning bolt 9.

[0025] After the limit column 4 and the positioning hole 6 are inserted into the connection, the staff can manually release the sliding button 8. At this time, the elastic positioning structure 10 is no longer manually compressed, and the spiral spring 1001 resets itself and makes the T-shaped cap 1002 and the hexagonal positioning bolt 9 move up until the hexagonal positioning bolt 9 is inserted into the hexagonal through hole 401. Compared with the solution of using special connecting parts, the design of components such as the limit column 4, positioning hole 6, hexagonal positioning bolt 9, and elastic positioning structure 10 is simpler, easier to install and maintain. If the slope net needs to be replaced or repaired, the operator can operate more conveniently, reducing maintenance costs and time costs.

[0026] When the embodiment of the present application is in use, the staff first takes out at least two of the dam slope protection nets. At this time, the left and right side edges between the two adjacent circular protection frames 1 are overlapped through the positioning hole 6 and the limiting column 4, that is, the limiting column 4 on the back of the tongue 3 is completely inserted into the positioning hole 6, and the side edges between the adjacent circular protection frames 1 are limited in the Y-axis direction by the limiting column 4 and the positioning hole 6. When the limiting column 4 and the positioning hole 6 are inserted to the extreme position, the hexagonal through hole 401 and the hexagonal positioning bolt 9 will be in a concentric state, and the hexagonal positioning bolt 9 will be automatically pushed into the hexagonal through hole 401 under the elastic action of the elastic positioning structure 10, so that the hexagonal positioning bolt 9 and the hexagonal through hole 401 are used to limit the side edges between the adjacent circular protection frames 1 in the Z-axis direction. At this time, the two The dam slope protection net is connected in the X-axis direction, and then the staff covers the connected dam slope protection net on the slope, and uses the positioning foot 2 and the thread to fix the dam slope protection net on the slope. The two adjacent slope protection net frames adopt Y-axis and Z-axis two-way limiters, which have higher stability compared to the limit in a single connection direction. The combination of Y-axis limit and Z-axis limit can effectively fix the position of the slope protection net to prevent it from shifting or tilting under external forces such as water flow impact and soil pressure, thereby enhancing the stability and reliability of the connection. At the same time, the use of multi-dimensional limiters can effectively disperse the stress on the connection part, reduce the problem of local stress concentration, reduce the fatigue damage and fracture risk of the connector, and extend the service life of the slope protection net.
