Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and more specifically, particularly relates to a slope protection net. Background Technique

[0002] Most water conservancy projects are in complex terrain environments. In these areas, complex situations such as high and steep slopes and crisscrossed gullies are common. In order to effectively prevent rock blocks on the slope from rolling down, people usually set up protection nets at the slope. The slope protection nets are mainly divided into two categories: active protection nets and passive protection nets. Among them, the passive protection net is an interception protection system. The passive protection net generally consists of components such as wire rope nets, ring nets, and high-strength steel wire grids. With the help of steel columns, support ropes, anchor ropes, etc., a solid three-dimensional protection structure is built. The main function of the passive protection net is to intercept falling rocks, soil bodies, etc. that roll or slide down from the slope, so as to block the danger outside the protection net and avoid damage to the water conservancy project facilities and the lives of personnel below.

[0003] A slope protection net disclosed according to the application number: CN202223065455.0, which relates to the technical field of protection nets, includes a first support member and a second support member. A sliding base is movably connected to the inner surface of the second support member. A top rod is inserted into the surface of the sliding base, and a connecting rod is arranged at one end of the top rod. By setting the first support member and the second support member, and setting a limiting member on the inner wall of the second support member, the connecting plate is moved by pushing the top rod, and then the insertion block fixedly connected to the connecting plate is inserted into the limiting member to fix the first support member; conversely, pulling the top rod enables the first support member to be movably adjusted, achieving the purpose of adjusting the heights of the first support member and the second support member, so that workers do not need to use heightening equipment to install a tightening device and a connecting rope on the top of the first support member by themselves, improving the technical problem that the existing protection net cannot use heightening equipment in special terrains, such as beside inclined geology, and the height of workers cannot reach the top of the support, so the protection net cannot be installed.

[0004] Based on the above, during the use of the existing slope protection net, once a rock rolls down from the slope and impacts the protection net, due to the huge impact force of the rock, it is easy to damage the protection net, which will not only cause economic losses, but also trigger safety hazards and pose a threat to the safety of surrounding personnel and facilities. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a slope protection net to solve the problem that during the use of the existing slope protection net, once a rock rolls down from the slope and impacts the protection net, due to the huge impact force of the rock, it is easy to damage the protection net, which will not only cause economic losses, but also trigger safety hazards and pose a threat to the safety of surrounding personnel and facilities.

[0006] The purpose and efficacy of a slope protection net of the utility model are achieved by the following specific technical means:

[0007] A slope protection net includes columns, bases, top shells, rotating shafts, high-strength elastic bands, fixing plates, protection components, installation mechanisms, and protection buffer mechanisms; there are two columns; there are two bases, and the two bases are respectively fixedly connected to the lower end faces of the two columns; there are two top shells, and the two top shells are respectively fixedly connected to the upper end faces of the two columns; there are two rotating shafts, and the two rotating shafts are respectively rotatably connected to the inner sides of the two columns; there are two high-strength elastic bands, and the two high-strength elastic bands are respectively wound around the outer sides of the two rotating shafts; there are two fixing plates, and the two fixing plates are respectively fixedly connected to the outer sides of the two high-strength elastic bands; the protection components are fixedly connected to the inner sides of the two fixing plates; the installation mechanisms are arranged at the front ends of the columns; the protection buffer mechanisms are arranged inside the top shells.

[0008] Furthermore, the installation mechanism includes: fixing frames, articulated frames, and steel wires; there are two fixing frames, and the two fixing frames are respectively fixedly connected to the front end faces of the two columns; there are two articulated frames, and the two articulated frames are respectively articulated inside the two fixing frames; there are two steel wires, and the two steel wires are respectively fixedly connected to the rear end faces of the two articulated frames.

[0009] Furthermore, the installation mechanism also includes: embedded anchor rods and articulated blocks; there are two embedded anchor rods, and the two embedded anchor rods are respectively installed at the rear ends of the two steel wires. The embedded anchor rods are of a structure that is thinner at the top and thicker at the bottom; there are two groups of articulated blocks, and the two groups of articulated blocks are respectively articulated at the lower ends of the two embedded anchor rods. A torsion spring is provided at the connection between the articulated blocks and the embedded anchor rods.

[0010] Furthermore, the protection buffer mechanism includes: fixed seats and buffer grooves; there are two groups of fixed seats, and the two groups of fixed seats are respectively fixedly connected to the inner sides of the two bases and the two top shells; there are two groups of buffer grooves, and the two groups of buffer grooves are respectively opened on the inner sides of the two groups of fixed seats.

[0011] Furthermore, the protection buffer mechanism also includes: square rods and rotating seats; there are two groups of square rods, and the two groups of square rods are respectively fixedly connected to the outer sides of the two rotating shafts; there are two groups of rotating seats, and the two groups of rotating seats are respectively slidably connected to the outer sides of the two groups of square rods.

[0012] Furthermore, the protection buffer mechanism also includes: buffer blocks and buffer springs; there are two groups of buffer blocks, and the two groups of buffer blocks are respectively fixedly connected to the outer sides of the two groups of rotating seats; there are two groups of buffer springs, and one ends of the two groups of buffer springs are respectively fixedly connected to the outer sides of the two groups of rotating seats, and the other ends of the two groups of buffer springs are respectively fixedly connected to the inner sides of the two bases and the two top shells.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the setting of the installation mechanism, the utility model achieves the stable installation of the slope protection net. After the base is installed on the slope, holes need to be drilled on the slope, then concrete is injected into the holes, and then the embedded anchor rod is inserted into the holes. During the process of inserting the embedded anchor rod into the holes, the hinged block will automatically open under the action of the torsion spring. After the concrete solidifies, the embedded anchor rod is firmly fixed. In this way, the installation stability of the slope protection net is greatly improved, and it can withstand greater impact force, thus effectively improving the safety factor; through the setting of the protection and buffering mechanism, the effective buffering of the impact force of the rolling rocks is realized. When a rock rolls on the slope, the protection part will first block the rock. When the rock impacts the protection part, the high-strength elastic band will be stretched. During this process, the high-strength elastic band will drive the rotation of the rotating shaft, and the rotation of the rotating shaft will cause the rotating seat to rotate through the square rod. At this time, the buffer groove and the buffer block will, under the action of the buffer spring, produce a buffering effect on the rotating seat, so as to consume the impact force brought by the rolling of the rock, avoid the damage of the slope protection net caused by excessive rock impact force, thus effectively reducing the impact force of the rock and preventing the protection net from being damaged by the strong rock impact force. This not only prolongs the service life of the protection net, reduces the economic loss, but also further improves the safety of the entire protection system; through the coordinated action of the above mechanisms, the utility model not only ensures the stable installation of the slope protection net, enhances its ability to resist impact force, improves the safety level, but also realizes the buffering of the impact force of the rolling rocks, achieving multiple effects of prolonging the service life, reducing the economic loss and improving the safety.
