Description

Technical Field

[0001] This utility model relates to the field of slope protection netting technology, and in particular to a slope protection mechanism for water conservancy projects. Background Technology

[0002] In water conservancy projects, slope protection nets are important facilities for preventing natural disasters such as soil collapse, siltation, landslides and debris flows. They are usually woven from high-strength steel wires and have the characteristics of corrosion resistance, wear resistance, waterproofing, water permeability and air permeability, which can effectively protect the stability of slope structures.

[0003] However, during the transportation and storage of slope protection netting, it needs to be bent and folded before stacking. Because the slope protection netting body is made of woven steel wire, it has strong elasticity. After being folded, it is easy to return to its original position and unfold under the action of elasticity, making it difficult to maintain the folded state. This not only increases the storage space occupied, but also causes inconvenience during transportation due to its loose shape. It may even damage the netting due to mutual friction and collision, affecting its subsequent performance. Utility Model Content

[0004] This utility model is a slope protection mechanism for water conservancy projects that is proposed to solve the problem that after the slope protection net is folded, it is easy for the slope protection net to return to its original position under the action of its own elasticity, which makes it inconvenient to store and transport.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slope protection mechanism for water conservancy projects, comprising a protective net body, a reinforcing frame surrounding the outer periphery of the protective net body, and a plurality of sets of protruding blocks symmetrically protruding on the left and right sides of the reinforcing frame along the horizontal direction;

[0006] Rigid ropes are provided on both sides of the reinforcing frame at the positions corresponding to the protruding blocks. One end of the rigid rope is fixed to the outer wall of one of the protruding blocks, and the other end moves horizontally through the inner wall of the other protruding block and extends to the outside.

[0007] An auxiliary support block is fixed at the position where the rigid rope passes through the protruding block. A hole block is symmetrically protruded on the left and right sides of the auxiliary support block. A first screw and a second screw are mounted between the two hole blocks. The first screw and the second screw are coaxially fixed and have opposite thread directions. They are respectively adapted to the threads of the hole blocks on the corresponding sides.

[0008] Both the first screw and the second screw have a clamping block threaded onto their outer circumferential surfaces. The clamping block is located between the protruding block and the perforated block, and the two clamping blocks can move towards or away from each other in the horizontal direction under the rotational drive of the first screw and the second screw to clamp or release the rigid rope.

[0009] Preferably, the clamping block has a sliding block protruding on the side facing the auxiliary support block, and the auxiliary support block has a sliding groove recessed at the position corresponding to the sliding block. The sliding block and the sliding groove are slidably adapted to each other in the horizontal direction to limit the movement trajectory of the clamping block.

[0010] Preferably, the outer ends of the first screw and the second screw, which are opposite to each other, are fixed with operating knobs. The outer peripheral surface of the operating knobs is provided with anti-slip protrusions to facilitate gripping and driving the screws to rotate.

[0011] Preferably, anti-slip rubber blocks are fixed to the inner sides of the two clamping blocks facing each other. The surface of the anti-slip rubber blocks is recessed with an arc-shaped groove adapted to the rigid rope to enhance the clamping stability of the rigid rope.

[0012] Preferably, a limiting disc is fixed to the end of the rigid rope away from the protruding block, and the outer diameter of the limiting disc is larger than the diameter of the rigid rope to prevent the rigid rope from slipping out of the protruding block.

[0013] Preferably, the protective net body has perforated blocks protruding at each of the four corners, and the reinforcing frame has stud pins fixed at the positions corresponding to the perforated blocks. One end of the stud pin moves vertically through the inner wall of the perforated block to achieve a detachable connection between the protective net body and the reinforcing frame.

[0014] Preferably, a fastening nut is threaded onto one end of the stud pin that protrudes from the through-hole block. The fastening nut can rotate along the axial direction of the stud pin and press against the surface of the through-hole block to lock and fix the through-hole block.

[0015] Preferably, a buffer washer is fitted on the stud pin, and the buffer washer is located between the fastening nut and the through block to relieve the squeezing and wear of the through block by the fastening nut.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] To solve the problem of folding and repositioning, and facilitate storage and transportation: By setting up structures such as rigid ropes, extension blocks, clamping blocks and screw assemblies, the slope protection net can be tightened by pulling the rigid ropes after folding, and the clamping blocks are used to clamp and fix the ropes, effectively limiting the repositioning tendency of the net due to its own elasticity, ensuring the stability of the folded state, reducing storage space occupation and improving transportation convenience.

[0018] Enhanced structural stability and durability: The reinforced frame provides effective support and protection for the edges of the protective netting body, preventing loosening or damage due to concentrated stress. The combination of studs, fastening nuts, and buffer washers ensures a firm connection between the protective netting body and the reinforced frame, while also relieving fastening pressure, preventing component wear, and extending the overall service life.

[0019] Easy to operate and highly adaptable: The clamping block is opened and closed by rotating the screw through the operating knob, which is simple and labor-saving; the anti-slip rubber block and rope fit design and the anti-detachment function of the limiting disc improve the fixation reliability; the overall structure can be adapted to different specifications of slope protection nets and is suitable for slope protection scenarios of various water conservancy projects.

[0024] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a slope protection mechanism for water conservancy projects, aiming to solve the problem that traditional slope protection nets, due to their elasticity, are prone to easy repositioning after folding, making them inconvenient to store and transport. Its specific structure is as follows: The water conservancy slope protection net includes a protective net body 1, which is woven from high-strength galvanized steel wire. This body effectively intercepts soil while not affecting water flow, maintaining the ecological balance of the water conservancy system.

[0025] A reinforcing frame 2 is provided around the outer periphery of the main body 1 of the protective net. The reinforcing frame 2 is made of alloy steel and has a rectangular cross-section. Its inner sidewall is pre-fixed to the edge of the main body 1 of the protective net by welding or bolts to enhance the overall structural strength and prevent the edge from loosening due to stress concentration.

[0026] Curling and fixing mechanism: Several sets of protruding blocks 7 are symmetrically protruding along the horizontal direction on the left and right side walls of the reinforcing frame 2. In this embodiment, each set has 2 blocks, symmetrically distributed at the front and rear ends of the same side of the reinforcing frame 2. The protruding blocks 7 are cuboid block structures integrally formed with the reinforcing frame 2, and have through holes along the horizontal direction inside for ropes to pass through.

[0027] For each set of protruding blocks 7, a rigid rope 8 is provided on both sides of the reinforcing frame 2. The rope can be made of steel wire or high-strength nylon with good UV resistance. One end of the rigid rope 8 is fixedly connected to the outer wall of one of the protruding blocks 7 using a rope clamp, and the other end moves horizontally through the through-hole of another protruding block 7 in the same set, extending outwards towards the outside of the reinforcing frame 2.

[0028] At the position where the rigid rope 8 passes through the protruding block 7, an auxiliary support block 9 in the shape of a cuboid plate is vertically fixed on its outer side wall. The left and right sides of the auxiliary support block 9 are symmetrically protruding with perforated blocks 10 in the horizontal direction. The axis of the two perforated blocks 10 is collinear, and internal threads are opened inside.

[0029] A first screw 11 and a second screw 12 are mounted between the two perforated blocks 10. The two are coaxial and integral. The thread direction of the first screw 11 is opposite to that of the second screw 12, and they are respectively adapted to the internal threads of the perforated blocks 10 on the corresponding side.

[0030] Both the first screw 11 and the second screw 12 have clamping blocks 13 threaded onto their outer circumferential surfaces. The clamping blocks 13 are located between the protruding block 7 and the perforated block 10, with their inner sidewalls facing the outer circumferential surface of the rigid rope 8. When the first screw 11 and the second screw 12 are rotated, because the threads are in opposite directions, the two clamping blocks 13 can move synchronously towards or away from each other in the horizontal direction: when moving towards each other, the rigid rope 8 can be clamped between the two clamping blocks 13; when moving away from each other, the rigid rope 8 is released.

[0031] Auxiliary limiting structure: In order to limit the movement trajectory of the clamping block 13, a sliding block 14 is provided on the side of the clamping block 13 facing the auxiliary support block 9. Correspondingly, a sliding groove 15 adapted to the sliding block 14 is recessed on the surface of the auxiliary support block 9 in the horizontal direction. The sliding block 14 can slide smoothly along the inner wall of the sliding groove 15 to prevent the clamping block 13 from circumferentially shifting as the screw rotates.

[0032] To facilitate the rotation of the screws, the outer ends of the first screw 11 and the second screw 12, which are opposite to each other, are respectively fixed with operating knobs 16. The outer circumferential surface of the operating knobs 16 is evenly distributed with anti-slip protrusions, which can increase the grip friction and facilitate manual rotation.

[0033] To enhance the clamping stability of the rigid rope 8, anti-slip rubber blocks 17 made of nitrile rubber are glued to the inner sidewalls of the two clamping blocks 13 facing each other. The blocks have an arc-shaped groove on their surface that is adapted to the outer circumference of the rigid rope 8. When the clamping blocks 13 are clamped, the arc-shaped groove can fit tightly with the rigid rope 8 to prevent the rope from slipping.

[0034] To prevent the rigid rope 8 from completely slipping out of the through hole of the protruding block 7, a limiting disc 18 is fixed to the free end of the rigid rope 8 away from the protruding block 7 by welding or riveting. The outer diameter of the limiting disc 18 is larger than the inner diameter of the through hole of the protruding block 7, which can mechanically limit the maximum pull-out distance of the rope.

[0035] Connection structure between the protective net and the reinforcing frame: At each of the four corners of the protective net body 1, a perforated metal block 3 is welded and fixed, with through holes inside. Correspondingly, each of the four corners of the reinforcing frame 2 has a vertically fixed stud pin 4 on its inner sidewall. The surface roughness of the thread reaches [specific value], and its axis is collinear with the axis of the through hole of the perforated block 3. Its outer diameter is slightly smaller than the inner diameter of the through hole, allowing it to be movably inserted through the through hole of the perforated block 3, thus achieving initial positioning of the protective net body 1 and the reinforcing frame 2.

[0036] To secure the protective net body 1 to the reinforcing frame 2, a hexagonal nut 5 is threaded onto one end of the stud pin 4 that protrudes from the perforated block 3. The nut 5 fits well with the external thread of the stud pin 4, allowing for smooth and unobstructed engagement. By tightening the nut 5, its end face moves axially along the stud pin 4 and presses against the surface of the perforated block 3, thus securing the perforated block 3.

[0037] To alleviate the direct crushing wear of the fastening nut 5 on the through block 3, a buffer washer 6 is fitted on the stud pin 4. This could be a metal spring washer or a rubber washer. The buffer washer 6 is located between the fastening nut 5 and the through block 3, and can absorb part of the locking force through its own elastic deformation, while preventing the nut from loosening.

[0038] Manufacturing Process and Quality Control: Protective Net Body 1. Weaving Process: A twisted weaving method is used to ensure each steel wire is tightly wound without loosening or unraveling. After weaving, a comprehensive inspection is conducted to check the uniformity of the mesh openings and the integrity of the galvanized layer on the steel wire surface, ensuring no defects such as incomplete plating or bubbles, and guaranteeing that the tensile strength meets design requirements.

[0039] Reinforcement frame 2 processing technology: Welding forming process is adopted. During welding, the current, voltage and welding speed are strictly controlled to ensure that the weld is uniform, firm and free from false welds and cracks.

[0040] Component manufacturing quality control: During the manufacturing process of components such as protruding block 7, auxiliary support block 9, and perforated block 10, control the casting temperature, cooling rate, casting process or machining accuracy to ensure the absence of defects such as sand holes and air holes, and verify dimensional accuracy and surface quality. Stud pin 4 and fastening nut 5 must pass hardness and engagement tests to ensure fastening performance.

[0041] Installation and Maintenance Instructions: Clean the slope surface according to design requirements, ensuring it is flat and free of debris. Unfold the main body 1 of the protective netting to cover the slope surface, adjust its position so that the edges are aligned with the slope boundary, and place the reinforcing frame 2 so that its inner wall fits against the edge of the protective netting. Align the through hole of the perforated block 3 with the stud pin 4 and insert it. Place the buffer washer 6 and the fastening nut 5 on the protruding end of the stud pin 4 in sequence, and tighten the nut with a wrench to complete the fixation. Pull the rigid rope 8 to make the protective netting roll and fold along the reinforcing frame 2 to the appropriate size. Rotate the operating knob 16 to drive the screw to rotate, so that the clamping block 13 clamps the rope through the anti-slip rubber block 17 to complete the fixation.

[0042] Maintenance points: Regular inspection is recommended once a month: Check the main body of the protective net 1 for broken wires and deformed mesh; check the reinforcing frame 2 for deformation and detachment; check the studs 4 and fastening nuts 5 for looseness. Address any problems promptly, such as replacing broken wires, correcting deformations, repairing welds, and tightening.

[0043] Rope and rubber block inspection: Check the wear and breakage of the rigid rope 8. If the wear is slight, apply protective paint; if the wear is severe, replace it. Check the wear of the anti-slip rubber block 17. If it is not tightly attached, replace it in time.

[0044] Lubrication and maintenance: Apply lithium-based grease to the contact parts of the operating knob 16, screw, sliding block 14 and sliding groove 15 regularly to ensure smooth rotation and sliding.

[0045] Work process

[0046] Folding and fixing operation: During storage or transportation, pull the free end of the rigid rope 8 to make it slide along the through hole of the protruding block 7. Under the action of tension, the main body 1 of the protective net is rolled up and folded along the length of the reinforcing frame 2. After folding to the preset size, turn the operation knob 16 to drive the screw to rotate, so that the clamping blocks 13 move towards each other and clamp the rope through the anti-slip rubber block 17. Finally, wrap the excess rope around the outer perimeter of the folded slope protection net to complete the fixing.

[0047] Unfolding Operation: When in use, rotate the operating knob 16 in the opposite direction to loosen the rope of the clamping block 13. After the restraint is released, the slope protection net will naturally unfold under its own elasticity, and can then be laid and installed.

[0048] This embodiment effectively solves the problem of traditional slope protection nets being easily reset after folding through the above-mentioned structural design and process control, improves the convenience of storage and transportation, and enhances the overall strength, making it suitable for various water conservancy engineering slope protection scenarios.
