Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a slope protection net for water conservancy projects. Background Technology

[0002] A type of protective equipment used to protect geological structures such as hillsides and slopes is called a slope protection net. It is mainly used to prevent damage caused by natural disasters such as debris flows and landslides. Slope protection nets are usually made of high-strength steel wire mesh or steel wire rope mesh, and have the characteristics of high flexibility and high protective strength. They are easy to lay and install. There are various types of slope protection nets, including SNS flexible protective nets and active protection systems. SNS flexible protective nets are mainly composed of high-strength steel wire rope mesh. They prevent slope rock collapses and rolling down by covering and fastening. Active protection systems prevent slope rock collapses, rolling down, and flying rocks from blasting by covering and fastening.

[0003] Chinese Utility Model Patent Publication Number: CN 221523464 U discloses a slope protection net for water conservancy projects. This slope protection net allows for the upward pulling of a limiting block, simultaneously engaging the groove of another slope protection net body from one end of a protrusion. The limiting block is then released, and the telescopic rod and spring return to their original positions, thus limiting the engagement of the protrusion and side rod. Next, fixing bolts are screwed into the corresponding bolt holes, fixing the protrusion to the corresponding side rod of the other slope protection net body. Simultaneously, the other side can also engage with another slope protection net body. This facilitates splicing slope protection nets according to actual needs, allows for flexible size adjustment, and is easy to connect, improving utilization. However, while this slope protection net allows for quick connection of adjacent slope protection net bodies, it lacks a limiting structure. In harsh environments, adjacent slope protection net bodies are prone to separation, resulting in poor stability. Furthermore, adjacent slope protection net bodies can only be connected in a straight line, making it unsuitable for stepped slopes. Its adaptability is low, its practicality is poor, and it is not convenient for widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a slope protection net for water conservancy projects. It can effectively solve the problems of existing technologies, which can quickly connect adjacent slope protection net bodies, but do not have a limiting structure. In harsh environments, adjacent slope protection net bodies are prone to separation, have poor stability, and can only be connected in a straight line. They are not suitable for stepped slopes, have low adaptability, poor practicality, and are not easy to promote and use.

[0005] The technical solution adopted by this utility model is: a slope protection net for water conservancy projects, including a slope protection net body, a first installation frame and a second installation frame. A connecting component is provided between the first installation frame and the second installation frame. A limiting component is provided on the outer surface of the connecting component. A threaded hole is opened on the outer surface of the connecting component. A threaded hole is opened at one end of the first installation frame near the second installation frame. A fixing bolt is threadedly connected to the outer surface of the connecting component. An expansion bolt is threadedly connected to the outer surface of the first installation frame.

[0006] Preferably, the slope protection net body includes a corrosion-resistant layer, a high-toughness layer, a reinforcement layer, and a wear-resistant layer. The outer surface of the corrosion-resistant layer is provided with a high-toughness layer. The side of the high-toughness layer away from the corrosion-resistant layer is provided with a reinforcement layer. The side of the reinforcement layer away from the high-toughness layer is provided with a wear-resistant layer. The corrosion-resistant layer is a high-strength polypropylene fiber layer, and the high-toughness layer is a geosynthetic material layer.

[0007] Through the above technical solutions, the high-strength polypropylene fiber layer is corrosion-resistant, acid and alkali-resistant, and anti-aging. It is lightweight but has high strength and is suitable for preventing slope collapse and landslides. The geosynthetic material layer has high tensile strength and stability, which can enhance the stability and erosion resistance of the slope structure.

[0008] Preferably, the reinforcing layer is a steel wire layer, and the wear-resistant layer is a high-strength polyester fiber layer.

[0009] Through the above technical solutions, the steel wire layer has high tensile strength and corrosion resistance, which can effectively enhance the stability of the slope and prevent landslides and collapses. The high-strength polyester fiber layer has high strength and high durability, which can resist the impact of the slope and the erosion of water flow, and prevent slope erosion and collapse.

[0010] Preferably, the slope protection net body is located on the inner surface of the first mounting frame, the first mounting frame and the second mounting frame have the same structure, and the cross-section of the slope protection net body has a honeycomb structure.

[0011] Through the above technical solution, the slope protection net body is designed with a "honeycomb" structure in its cross section. This structure can interlock with each other, increasing its stability and making it less susceptible to damage from external forces. This structure makes the slope protection net body more robust and durable when facing water flow impact, strong wind and rain erosion.

[0012] Preferably, the connecting assembly includes a rotating shaft, a first connector, a second connector, a first positioning groove, and a second positioning groove. The first connector and the second connector are rotatably mounted on the outer surface of the rotating shaft. The first connector has a first positioning groove on the side near the first mounting frame. The first mounting frame has a second positioning groove on the end near the first connector. The first connector and the second connector have the same structure. The first mounting frame and the first connector are plugged into each other. The cross-section of the first connector is U-shaped.

[0013] Through the above technical solution and the design of the connecting components, the workers insert the connector one into the interior of the positioning groove two, so that the mounting frame one is submerged in the interior of the positioning groove one. This enables quick positioning between adjacent mounting frames one, which is convenient for subsequent fixing. Furthermore, the adjacent mounting frames one can rotate after being connected, making it suitable for stepped slopes and highly adaptable.

[0014] Preferably, the limiting component includes a groove, a fixed shaft, a rotating plate, a torsion spring, a first baffle, a second baffle, a limiting block, an arc-shaped groove, and a limiting groove. The fixed shaft is fixedly installed on the inner surface of the groove, the rotating plate is rotatably installed on the outer surface of the fixed shaft, and a torsion spring is provided on the outer surface of the fixed shaft. The first baffle is fixedly installed on the outer surface of the first baffle, the second baffle is fixedly installed on the inner surface of the groove, and a limiting block is fixedly installed on the outer surface of the first baffle. An arc-shaped groove and a limiting groove are provided at one end of the mounting frame near the first connector. The limiting block is adapted to the arc-shaped groove and the limiting groove. The first baffle and the second baffle abut against each other. One end of the torsion spring is fixedly installed to the fixed shaft, and the other end of the torsion spring is fixedly installed to the rotating plate.

[0015] Through the above technical solution and the design of the limiting component, when the connecting piece 1 is inserted into the interior of the positioning groove 2, the limiting block is squeezed when it comes into contact with the arc groove, the torsion spring is twisted, causing the rotating plate to rotate upward. When the mounting frame 1 is inserted into the interior of the positioning groove 1, the torsion spring rebounds and pushes the limiting block into the interior of the limiting groove, which can achieve initial fixation between adjacent mounting frames 1, and has high practicality.

[0016] Preferably, the fixing bolt extends through the first threaded hole and into the second threaded hole, and the first threaded hole and the second threaded hole are close to each other.

[0017] Through the above technical solution, by cooperating with the fixing bolts, threaded hole one and threaded hole two, after the adjacent mounting frames are initially fixed, the workers then extend the fixing bolts through threaded hole one into the interior of threaded hole two, making the connection between the adjacent mounting frames more secure. In harsh environments, this prevents the adjacent mounting frames from separating and affecting the normal use of the whole, resulting in high stability.

[0018] Compared with the prior art, this utility model provides a slope protection net for water conservancy projects, which has the following characteristics:

[0019] Beneficial effects:

[0020] 1. The slope protection net used in this water conservancy project, through the design of the connecting components, can achieve rapid positioning between adjacent installation frames, which is convenient for subsequent fixing.

[0021] 2. The slope protection net used in this water conservancy project can achieve initial fixation between adjacent installation frames through the design of the limiting components, which is highly practical. Through the cooperation of the fixing bolts, threaded hole one and threaded hole two, the connection between adjacent installation frames is more secure.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-5 As shown, the present invention provides a slope protection net for water conservancy projects, including a slope protection net body 1, a first installation frame 2 and a second installation frame 9. A connecting component 3 is provided between the first installation frame 2 and the second installation frame 9. A limit component 4 is provided on the outer surface of the connecting component 3. A threaded hole 5 is opened on the outer surface of the connecting component 3. A threaded hole 6 is opened at one end of the first installation frame 2 near the second installation frame 9. A fixing bolt 7 is threadedly connected to the outer surface of the connecting component 3. An expansion bolt 8 is threadedly connected to the outer surface of the first installation frame 2.

[0031] Specifically, the slope protection net body 1 includes a corrosion-resistant layer 101, a high-toughness layer 102, a reinforcement layer 103, and a wear-resistant layer 104. The high-toughness layer 102 is disposed on the outer surface of the corrosion-resistant layer 101. The reinforcement layer 103 is disposed on the side of the high-toughness layer 102 away from the corrosion-resistant layer 101, and the wear-resistant layer 104 is disposed on the side of the reinforcement layer 103 away from the high-toughness layer 102. The corrosion-resistant layer 101 is a high-strength polypropylene fiber layer, and the high-toughness layer 102 is a geosynthetic material layer. The advantages are that the high-strength polypropylene fiber layer is corrosion-resistant, acid and alkali-resistant, and anti-aging; it is lightweight yet high-strength, suitable for preventing slope collapse and landslides. The geosynthetic material layer has high tensile strength and stability, enhancing the stability and erosion resistance of the slope structure.

[0032] Specifically, the reinforcement layer 103 is a steel wire layer, and the wear-resistant layer 104 is a high-strength polyester fiber layer. The advantages are that the steel wire layer has high tensile strength and corrosion resistance, which can effectively enhance the stability of the slope and prevent landslides and collapses, while the high-strength polyester fiber layer has high strength and durability, which can resist the impact of the slope and the erosion of water flow, preventing slope erosion and collapse.

[0033] Specifically, the slope protection net body 1 is located on the inner surface of the mounting frame 2. The mounting frame 2 has the same structure as the mounting frame 9, and the cross-section of the slope protection net body 1 has a honeycomb structure. The advantage is that, through the honeycomb structure design of the cross-section of the slope protection net body 1, the structure can interlock with each other, increasing its stability and making it less susceptible to damage from external forces. This structure makes the slope protection net body 1 more robust and durable when facing water flow impact, strong winds, and rainwater erosion.

[0034] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the connecting component 3 includes a rotating shaft 301, a first connector 302, a second connector 303, a first positioning groove 304, and a second positioning groove 305. The first connector 302 and the second connector 303 are rotatably mounted on the outer surface of the rotating shaft 301. The first connector 302 has a first positioning groove 304 on the side near the first mounting frame 2. The second mounting frame 2 has a second positioning groove 305 on the end near the first connector 302. The first connector 302 and the second connector 303 have the same structure. The first mounting frame 2 and the first connector 302 are plugged in. The cross-section of the first connector 302 is U-shaped. The advantage is that, through the design of the connecting component 3, the workers insert the first connector 302 into the second positioning groove 305, so that the first mounting frame 2 is submerged in the first positioning groove 304. This allows for quick positioning between adjacent first mounting frames 2, which is convenient for subsequent fixing. Furthermore, the adjacent first mounting frames (2) can rotate after being connected, which is suitable for stepped slopes and has high adaptability.

[0036] Specifically, the limiting component 4 includes a groove 401, a fixed shaft 402, a rotating plate 403, a torsion spring 404, a first baffle 405, a second baffle 406, a limiting block 407, an arc-shaped groove 408, and a limiting groove 409. The fixed shaft 402 is fixedly installed on the inner surface of the groove 401, the rotating plate 403 is rotatably installed on the outer surface of the fixed shaft 402, the torsion spring 404 is provided on the outer surface of the fixed shaft 402, and the first baffle 405 is fixedly installed on the outer surface of the first baffle 405. A second baffle 406 is fixedly installed on the surface of the first baffle 405. A limiting block 407 is fixedly installed on the outer surface of the first baffle 405. An arc groove 408 and a limiting groove 409 are opened at one end of the mounting frame 2 near the connector 302. The limiting block 407 is adapted to the arc groove 408 and the limiting groove 409. The first baffle 405 and the second baffle 406 abut against each other. One end of the torsion spring 404 is fixedly installed with the fixed shaft 402, and the other end of the torsion spring 404 is fixedly installed with the rotating plate 403. The advantage is that, through the design of the limiting component 4, during the process of inserting the connector 302 into the positioning groove 305, when the limiting block 407 contacts the arc groove 408, the limiting block 407 is squeezed, the torsion spring 404 is twisted, causing the rotating plate 403 to rotate upward. When the mounting frame 2 is inserted into the positioning groove 304, the torsion spring 404 rebounds, pushing the limiting block 407 into the limiting groove 409, which can achieve initial fixation between adjacent mounting frames 2, and has high practicality.

[0037] Specifically, the fixing bolt 7 extends through threaded hole 5 to the interior of threaded hole 6, with threaded hole 5 and threaded hole 6 being close to each other. The advantage is that, through the cooperation of fixing bolt 7, threaded hole 5, and threaded hole 6, after the adjacent mounting frames 2 are initially fixed, the worker then extends fixing bolt 7 through threaded hole 5 to the interior of threaded hole 6, making the connection between adjacent mounting frames 2 more secure. This prevents the adjacent mounting frames 2 from separating in harsh environments, thus avoiding affecting the normal use of the entire system and ensuring high stability.

[0038] Working principle: During installation, the operator inserts connector 302 into the positioning groove 305, so that mounting frame 2 is submerged in the positioning groove 304. This allows for quick positioning between adjacent mounting frames 2, facilitating subsequent fixing. Furthermore, adjacent mounting frames (2) can rotate after connection, making it suitable for stepped slopes with high adaptability. During the process of inserting connector 302 into the positioning groove 305, when the limiting block 407 contacts the arc groove 408, the limiting block 407 is compressed, and the torsion spring 4... 04. Twisting causes the rotating plate 403 to rotate upwards. When the mounting frame 12 is inserted into the positioning groove 304, the torsion spring 404 rebounds, pushing the limiting block 407 into the limiting groove 409. This achieves initial fixation between adjacent mounting frames 12, which is highly practical. After the initial fixation between adjacent mounting frames 12 is completed, the worker then extends the fixing bolt 7 through the threaded hole 15 to the threaded hole 26, making the connection between adjacent mounting frames 12 more secure. This prevents adjacent mounting frames 12 from twisting in harsh environments. Separation of the soil and water layers can affect the normal use of the entire structure. While maintaining high stability, the design incorporates a corrosion-resistant layer (101) consisting of a high-strength polypropylene fiber layer and a high-toughness layer (102) consisting of a geosynthetic material layer. The high-strength polypropylene fiber layer is corrosion-resistant, acid and alkali-resistant, and anti-aging, lightweight yet high-strength, suitable for preventing slope collapse and landslides. The geosynthetic material layer possesses high tensile strength and stability, enhancing the stability and erosion resistance of the slope structure. This is further reinforced by a reinforcing layer (103) consisting of a steel wire layer and a wear-resistant layer (104) consisting of high-strength polyester fiber. The design incorporates multiple layers: a steel wire layer with high tensile strength and corrosion resistance, effectively enhancing slope stability and preventing landslides and collapses; a high-strength polyester fiber layer with high strength and durability, resisting slope impact and water erosion, preventing slope erosion and collapses; and a honeycomb structure in the cross-section of the slope protection net body 1, which interlocks with each other, increasing stability and making it less susceptible to damage from external forces. This structure makes the slope protection net body 1 more robust and durable in the face of water impact, strong winds, and rain erosion.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
