Description

Technical Field

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

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals.

[0003] Announcement No. CN220266428U: A slope protection net for water conservancy projects, comprising: a slope, on one side of which two mounting plates are fixedly installed, each mounting plate being rotatably connected to a rotating shaft, and threaded sleeves fixedly installed on both sides of the rotating shaft; and two connecting plates, each set on one side of the two mounting plates. When the slope protection net is damaged, simply rotate the limiting bolt to disassemble it from the threaded hole and threaded sleeve, thus releasing the limiting of the threaded sleeve. Then, rotating the protrusion drives the rotating shaft to rotate. Since the protrusion and threaded sleeve are parallel, the position of the threaded sleeve can be observed by checking the position of the protrusion. When the threaded sleeve rotates to the in-and-out position, the connecting plates can be disassembled from the mounting plates, thus completing the disassembly of the slope protection net and facilitating its replacement and maintenance.

[0004] The problem with the aforementioned patent is that it relies on additional limiting bolts to fix the slope protection net, which not only increases costs but may also lead to a decrease in the stability of the slope protection net due to loosening or damage of the bolts. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a slope protection net for water conservancy projects, which solves the problem of relying on additional limiting bolt auxiliary components for fixing the slope protection net. This not only increases costs, but may also lead to a decrease in the stability of the slope protection net due to loosening or damage of the bolts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a slope protection net for water conservancy projects, comprising a fixing plate, both ends of which are connected to an outer shell. Two sets of outer shells are parallel to the centerline of the fixing plate and are mirror images of each other. An installation assembly is provided inside the outer shell and connected to an installation plate. The installation assembly includes a worm gear, which meshes with a worm wheel, and the worm wheel is rotatably disposed on the bottom surface of the outer shell. The shaft of the worm wheel is connected to a first protrusion. A rotating rod is fixed at the center of the top surface of the first protrusion, and the rotating rod passes through and rotatably connects to the outer shell. A second protrusion is fixed at the end of the rotating rod. The second protrusion engages with a limiting cavity through a slot provided on the bottom surface of the installation plate. The limiting cavity is located at both ends of the installation plate. The installation plates are arranged in pairs, and the opposite side of one set of installation plates is connected to both ends of the protective net.

[0007] The beneficial effects of this utility model are:

[0008] The meshing principle of worm gear and worm wheel allows for quick installation and disassembly of the slope protection net through simple rotation. The worm gear and worm wheel mechanism has a self-locking function, ensuring the stability of the slope protection net without the need for additional limit bolts or other auxiliary components. This simplifies the structure, reduces costs, and improves the safety and reliability of the slope protection net.

[0009] To remove the mounting plate from the top surface of the housing:

[0010] As a further improvement to the above technical solution: a sliding rod is slidably installed through one side of the inner wall of the outer shell, and a protrusion is fixed to the end of the sliding rod facing into the outer shell. The end of the sliding rod away from the extrusion block is sprayed with red paint.

[0011] The beneficial effects of this improvement are as follows: when the protrusion one rotates and squeezes the extrusion block connected to the slide rod one, the slide rod one slides to the outside of the outer shell. The red paint sprayed at the end of the slide rod one is exposed as the slide rod one slides. The user can judge whether the state of the protrusion two coincides with the position of the limiting cavity based on whether the red paint of the slide rod one is exposed, so that the mounting plate can be removed from the top surface of the outer shell.

[0012] To ensure the mounting plate is securely mounted on the top surface of the housing:

[0013] As a further improvement to the above technical solution: a sliding rod 2 is slidably installed through the inner wall of the other side of the outer shell, and a pressing block is fixed to the end of the sliding rod 2 facing into the outer shell. The end of the sliding rod 2 away from the pressing block is sprayed with green paint.

[0014] The beneficial effects of this improvement are as follows: when the protrusion one rotates and squeezes the extrusion block connected to the slide rod two, the slide rod two slides to the outside of the outer shell. The green paint sprayed on the end of the slide rod two is exposed as the slide rod two slides. The user can judge whether the state of the protrusion two intersects with the position of the limiting cavity based on whether the green paint of the slide rod two is exposed, thereby limiting the installation plate to the top surface of the outer shell.

[0015] In order for slider one and slider two to slide into the outer casing:

[0016] As a further improvement to the above technical solution: springs are sleeved on the outer sides of both slide rod one and slide rod two, and the two ends of the springs are respectively connected to the inner wall of the outer shell and the extrusion block.

[0017] The beneficial effects of this improvement are: the elastic potential energy of the spring allows the first protrusion to release its pressure on the compression block, and the elastic potential energy of the spring allows the first and second slide rods to slide into the outer shell.

[0018] To secure the outer casing and fixing plate to the slope protection:

[0019] As a further improvement to the above technical solution: the fixing plate is provided with a number of mounting holes at equal intervals, and the anchor rod passes through the sliding connection mounting holes.

[0020] The beneficial effect of this improvement is that the outer shell and fixing plate can be fixed to the slope by means of the anchor rod passing through the installation hole.

[0021] To limit the movement of the mounting plate:

[0022] As a further improvement to the above technical solution: the bottom surface of the limiting cavity is provided with a slot through the bottom surface of the mounting plate, and the inner diameter of the slot is not less than the inner diameter of the second protrusion.

[0023] The beneficial effects of this improvement are as follows: the second protrusion slides into the limiting cavity through the slot, and the position of the second protrusion is staggered with the position of the slot by adjusting the mounting components, thereby limiting the mounting plate.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0031] like Figure 1-4 As shown, a slope protection net for water conservancy projects includes a fixing plate 2. Both ends of the fixing plate 2 are connected to an outer shell 1. Two sets of outer shells 1 are parallel to the centerline of the fixing plate 2 and are mirror images of each other. An installation assembly 6 is provided inside the outer shell 1 and is connected to an installation plate 4. The installation assembly 6 includes a worm gear 601, which meshes with a worm wheel 605. The worm wheel 605 is rotatably disposed on the bottom surface of the outer shell 1. The shaft of the worm wheel 605 is connected to a first protrusion 602. A rotating rod is fixed at the center of the top surface of the first protrusion 602. The rotating rod passes through and rotatably connects to the outer shell 1. A second protrusion 603 is fixed at the end of the rotating rod. The second protrusion 603 is engaged with a limiting cavity 401 through a slot 402 provided on the bottom surface of the installation plate 4. The limiting cavity 401 is opened in both ends of the installation plate 4. The installation plates 4 are in pairs, and the opposite side of one set of installation plates 4 is connected to both ends of a protective net 5.

[0032] A sliding rod 604 is slidably mounted through one side of the inner wall of the outer shell 1, and a protrusion 603 is fixed to the end of the sliding rod 604 facing the inner side of the outer shell 1. The end of the sliding rod 604 away from the extrusion block 607 is coated with red paint. When the protrusion 602 rotates and extrudes the extrusion block 607 connected to the sliding rod 604, the sliding rod 604 slides to the outside of the outer shell 1. The red paint sprayed at the end of the sliding rod 604 is exposed as the sliding rod 604 slides. The user can judge whether the state of the protrusion 603 coincides with the position of the limiting cavity 401 by whether the red paint of the sliding rod 604 is exposed, so that the mounting plate 4 can be removed from the top surface of the outer shell 1.

[0033] A sliding rod 606 is slidably mounted through the inner wall of the other side of the outer shell 1, and a pressing block 607 is fixed to the end of the sliding rod 606 facing the inner side of the outer shell 1. The end of the sliding rod 606 away from the pressing block 607 is sprayed with green paint. When the protrusion 602 rotates and presses the pressing block 607 connected to the sliding rod 606, the sliding rod 606 slides to the outside of the outer shell 1. The green paint sprayed at the end of the sliding rod 606 is exposed as the sliding rod 606 slides. The user can judge whether the state of the protrusion 603 intersects with the position of the limiting cavity 401 by whether the green paint of the sliding rod 606 is exposed, thereby limiting the mounting plate 4 to be installed on the top surface of the outer shell 1.

[0034] Springs are fitted on the outer sides of both slide rod 604 and slide rod 606. The two ends of the springs are connected to the inner wall of the outer shell 1 and the pressing block 607, respectively. The elastic potential energy of the springs allows slide rod 604 and slide rod 606 to slide into the outer shell 1 when the protrusion 602 releases its pressure on the pressing block 607.

[0035] The fixing plate 2 has several mounting holes equidistantly through it, and the anchor rod 3 slides through the mounting holes; the outer shell 1 and the fixing plate 2 can be fixed to the slope protection by the anchor rod 3 through the mounting holes.

[0036] The bottom surface of the limiting cavity 401 penetrates the bottom surface of the mounting plate 4 and has a slot 402. The inner diameter of the slot 402 is not less than the inner diameter of the second protrusion 603. The second protrusion 603 slides into the limiting cavity 401 through the slot 402. The mounting component 6 is adjusted to make the second protrusion 603 rotate and its position intersect with that of the slot 402, thereby limiting the mounting plate 4.

[0037] The working principle and usage process of this utility model are as follows: When using this device, the user can first insert the anchor rod 3 into the mounting hole to limit and install the outer shell 1 and the fixing plate 2 on the slope. Then, the slot 402 at the bottom of the mounting plate 4 is aligned with the second protrusion 603. In the initial state, the second protrusion 603 coincides with the slot 402, and the second protrusion 603 slides along the slot 402 into the limiting cavity 401. The user rotates the worm gear 601. The rotating worm gear 601 causes the meshing worm wheel 605 to drive the rotation of the first protrusion 602 and the second protrusion 603. As the first protrusion 602 rotates, when it rotates to press the pressing block 607 connected to the first slide rod 604, the slide rod 604... The red paint at the end slides out to the outside of the outer shell 1. The user can stop rotating when the second protrusion 603 is completely aligned with the position of the slot 402 to complete the installation of the mounting plate 4, i.e., the installation of the protective net 5. The worm 601 and worm wheel 605 have self-locking characteristics and do not require additional operation. Similarly, when the protective net 5 needs to be disassembled and replaced, the worm 601 can be rotated in the opposite direction to make the first protrusion 602 rotate and press the pressing block 607 connected to the second slide rod 606. The green paint at the end of the second slide rod 606 slides out to the outside of the outer shell 1. The user can determine that the second protrusion 603 is aligned with the position of the slot 402 and then remove the mounting plate 4 upwards to complete the disassembly of the protective net 5.
