Description

Technical Field

[0001] This utility model relates to water conservancy projects, and more specifically, to water conservancy slope protection nets. Background Technology

[0002] Hydraulic slope protection netting is an important engineering material used for slope protection and reinforcement of riverbanks and embankments to prevent water erosion of the land. It has numerous advantages and applications, and is an effective method for land slope protection and soil erosion prevention.

[0003] Chinese patent CN212582594U discloses a slope protection net for water conservancy projects. Its key technical features include: an upper horizontal section, a lower horizontal section, a central inclined section, and several clamping mechanisms. The upper horizontal section is located at the top of the slope, and the lower horizontal section is located at the bottom. The central inclined section is integrally connected between the upper and lower horizontal sections. The bottom of each clamping mechanism passes through the upper horizontal section and connects to the top of the slope, while the bottom of the lower horizontal section also passes through the lower horizontal section and connects to the bottom of the slope. The inclined section includes several wire mesh sheets laid out at intervals. Each rectangular wire mesh sheet has connectors at its four corners. Adjacent wire mesh sheets are detachably connected to their corresponding connectors with steel wires. If a part of the slope protection net is damaged, only the damaged wire mesh sheet needs to be replaced, thus facilitating repair.

[0004] However, the connectors for this type of slope protection mesh are bolts and nuts. Therefore, when replacing the wire mesh, tools are needed to first remove the nuts from the bolts and then take out the steel wires that are sleeved on the bolts. Since the steel wires are connected to the screws of adjacent wire mesh, it means that in addition to the four nuts on the wire mesh to be replaced, the nuts on the adjacent wire mesh also need to be removed during disassembly. This results in the need to tighten a large number of nuts during the replacement of damaged wire mesh, which is time-consuming, laborious, and inconvenient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water conservancy slope protection net, which makes the replacement of wire mesh more convenient.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water conservancy slope protection net, comprising a main frame for fixing on a slope and several wire mesh sheets that can be detachably installed on the main frame. The main frame has several mounting grooves for installing the wire mesh sheets. A pressure plate is provided in the mounting groove to prevent the wire mesh sheets from falling out of the mounting groove. Several slots are provided on the inner side wall of the mounting groove. Sliding grooves are provided on both sides of the pressure plate. Both ends of the sliding groove are slidably connected to a locking block for locking into the slot. A rack is fixedly connected to the two locking blocks facing each other in the same sliding groove. A gear is meshed between the two racks. A knob is provided on the pressure plate for driving the gear to rotate.

[0008] The present invention is further configured such that: both sides of the pressure plate are provided with sliding grooves, the card block is slidably connected in the sliding grooves, and a driving component for driving the card block to slide is provided in the sliding grooves.

[0009] The present invention is further configured such that: the driving component includes a gear and two racks meshing with the gear; the gear is rotatably connected at the center of the slide groove; the two racks are located on both sides of the gear and slidably connected in the slide groove; the two racks are fixedly connected to a locking block; and the pressure plate is provided with a knob for driving the gear to rotate.

[0010] The present invention is further configured such that: protrusions are provided at both ends of the gear in the groove, and a spring is provided between the protrusions and the locking block to drive the locking block into the groove.

[0011] The present invention is further configured such that: a limiting post is provided on the card block, the spring is sleeved on the limiting post, and a through hole is provided on the protrusion for the limiting post to pass through.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figure 1-2As shown, the hydraulic slope protection net includes a main frame 1 for fixing on a slope and several wire mesh sheets 2 that can be detachably installed on the main frame 1. Several mounting grooves 3 are provided on the main frame 1 for installing the wire mesh sheets 2. Pressure plates 4 are provided in the mounting grooves 3 to prevent the wire mesh sheets 2 from detaching from the mounting grooves 3. Several slots 6 are provided on the inner sidewall of the mounting grooves 3. Sliding grooves 7 are provided on both sides of the pressure plate 4. Both ends of the sliding grooves 7 are slidably connected to locking blocks 5 for engaging with the locking grooves 6. Racks 9 are fixedly connected to the facing surfaces of two locking blocks 5 in the same sliding groove 7. Gears 8 mesh between the two racks 9. A knob 1 is provided on the pressure plate 4 to drive the gears 8 to rotate. 0. During the installation of slope protection netting on the slope, after clearing debris from the slope, the main frame 1 is fixed to the slope according to the design requirements. The wire mesh 2 is aligned with the installation groove 3 and then gently pushed in, ensuring that the wire mesh 2 completely covers the installation groove 3. Then, the pressure plate 4 is placed on top of the wire mesh 2. The construction worker can then operate the knob 10 on the pressure plate 4. As the knob 10 rotates, the gear 8 begins to rotate, which in turn drives the two gears 9 meshing with it to slide in the slide groove 7. The sliding of the gears 9 will synchronously drive the locking block 5 fixed on it to move. Under the synergistic action of the gear 8 and the gears 9, the locking block 5 will automatically slide to the locking groove 6 on the inner wall of the installation groove 3 and smoothly engage. Once the locking block 5 engages... Once fully engaged in slot 6, pressure plate 4 is securely fixed within mounting slot 3, simultaneously pressing wire mesh 2 tightly against the bottom wall of mounting slot 3. Wire mesh 2 is then clamped and confined within mounting slot 3. When wire mesh 2 in a specific area is damaged, it can be removed from the corresponding mounting slot 3 for replacement. Specifically, the knob 10 on pressure plate 4 is rotated in the opposite direction. This action causes gear 8 to rotate in the opposite direction. As gear 8 rotates in the opposite direction, rack 9 drives locking block 5 to slide in the sliding groove 7 in the opposite direction until locking block 5 completely slides out of slot 6. This releases the confinement of wire mesh 2 within mounting slot 3, allowing it to be lifted upwards and removed from mounting slot 3 for replacement. Applying pressure to the wire mesh 2 clamps and limits it within the mounting groove 3, ensuring its stable fixation and maintaining the integrity of the slope protection net. Simultaneously, by releasing the connector from the pressure plate 4, it can be removed from the mounting groove 3, thus releasing the restriction on the wire mesh 2 and allowing it to be easily detached. Then, by rotating the knob 10 to drive the gear 8, the racks 9 on both sides slide the locking blocks 5 within the sliding groove 7, enabling the locking blocks 5 to engage and disengage from the groove 6. This achieves the restriction and disengagement of the pressure plate 4 within the mounting groove 3, making the removal of the pressure plate 4 convenient and facilitating the replacement of the wire mesh.

[0021] See Figure 2-3As shown, protrusions 11 are provided at both ends of gear 8 within the slide groove 7. A spring 12 is provided between the protrusions 11 and the locking blocks 5 to drive the locking blocks 5 into the locking slot 6. During the installation of the pressure plate 4, turning the knob 10 causes the two locking blocks 5 on the same side to slide in the slide groove 7 in a direction facing each other, applying pressure to the spring 12, forcing the spring 12 to deform and be compressed. The compression of the spring 12 provides the power for the subsequent automatic locking into the locking slot 6. As the pressure plate 4 is further pressed down, the compression force of the spring 12 gradually increases. When the locking blocks 5 are aligned with the locking slot 6, turning the knob 10 is stopped, and the elastic force of the spring 12 quickly returns to normal. When released quickly, the locking block 5 slides rapidly into the slot 6. The spring 12 then rebounds, causing the locking block 5 to automatically engage in the slot 6, eliminating the need for manual operation. This makes installing the pressure plate 4 much easier. A limiting post 13 is provided on the locking block 5, and the spring 12 is fitted onto the limiting post 13. A through hole is provided on the protrusion 11 for the limiting post 13 to pass through. By setting the limiting post 13, it is ensured that the spring 12 always maintains the correct position and direction for deformation, avoiding displacement or bending. This helps to ensure the normal deformation of the spring 12 and prevents damage caused by excessive deformation.

[0022] See Figure 1-2 As shown, the wire mesh 2 is formed by several hot-dip galvanized steel wire ropes. The hot-dip galvanized steel wire ropes are high in strength and corrosion-resistant, giving the wire mesh 2 good strength and a long service life. Arc-shaped grooves 14 for accommodating the hot-dip galvanized steel wire ropes are provided on the bottom wall of the installation groove 3 and the bottom wall of the pressure plate 4. By providing arc-shaped grooves 14, the wire mesh 2 can be embedded into the arc-shaped grooves 14 after installation and fixation, achieving a tight fit. This not only enhances the connection stability between the wire mesh 2 and the installation groove 3 and pressure plate 4, but also effectively prevents the displacement or loosening of the hot-dip galvanized steel wire ropes. At the same time, the arc-shaped grooves 14 increase the contact area between the pressure plate 4, the bottom wall of the arc-shaped grooves 14 and the hot-dip galvanized steel wire ropes, which can disperse the pressure borne by the hot-dip galvanized steel wire ropes and reduce local stress concentration. This helps to extend the service life of the hot-dip galvanized steel wire ropes and improve the durability of the entire slope protection structure.
