Description

Technical Field

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

[0002] Water conservancy projects are used to control and regulate surface water and groundwater in nature. Water is a precious resource that is essential 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 and meet the water resource needs of people's lives and production. Water flow is guided by constructing slopes.

[0003] When protecting large slopes, protective nets are often used. These nets are installed and fixed by a series of carefully designed anchor rods that are deeply embedded in the soil or rock to ensure the stability of the nets. However, after being exposed to wind and sun, the nets are prone to weathering and need to be replaced. But because the nets are fixed in the soil by the anchor rods, they are not easy to pull out, making replacement difficult. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A slope protection mechanism for water conservancy and hydropower projects includes a fixed frame, one end of which is rotatably connected to the outer wall of a rotating shaft, and a protective net fixing mechanism is fixedly connected to the outer wall of the rotating shaft.

[0006] The protective net fixing mechanism includes a first fixing block, a sliding groove, a second fixing block, a second spring, a lifting plate, and a pull rod. One end of the first fixing block is fixedly connected to the outer wall of the rotating shaft. The sliding groove is opened at one end of the outer wall of the rotating shaft. The outer wall of one end of the second fixing block is engaged with the inner cavity of the sliding groove. The upper end of the second spring is fixedly connected to the upper end of the inner cavity of the first and second fixing blocks. The upper end of the lifting plate is fixedly connected to the lower end of the second spring. The lower end face of the lifting plate overlaps with the upper end face of the protective net, and the lower end face of the protective net overlaps with the inner cavity of the first and second fixing blocks. The outer wall of the pull rod is engaged with the inner wall of the first and second fixing blocks and rotatably connected to the upper end face of the lifting plate.

[0007] As an improvement to the above technical solution, the protective net fixing mechanism includes a screw, one end of which is rotatably connected to one end of the inner cavity of the slide groove, and the outer wall of the screw is threadedly connected to the inner cavity of one end of the second fixing block, and a knob is installed on one end of the screw.

[0008] As an improvement to the above technical solution, the lifting plate is equipped with a rack inside the first and second fixing blocks, and the rack overlaps with the outer wall of the protective net.

[0009] As an improvement to the above technical solution, a position fixing mechanism is provided on the outer wall of one end of the rotating shaft;

[0010] The position fixing mechanism includes a groove, a fixing plate, a first spring, and a fixing rod. The groove is formed on the outer wall of one side of the rotating shaft. One end of the fixing plate is fixedly connected to one end of the fixing frame. The upper end of the first spring is fixedly connected to the lower end face of the fixing plate. The outer wall of the fixing rod penetrates the inner wall of the fixing plate and engages with the inner cavity of the groove. A limiting plate is installed on the outer wall of the fixing rod, and the upper end of the limiting plate is fixedly connected to the lower end of the first spring.

[0011] As an improvement to the above technical solution, the inner cavity of the slide is rectangular and is engaged with the outer wall of one end of the second fixing block.

[0012] The beneficial effects of this utility model are:

[0013] By pulling a lever, the lever moves upward, which in turn moves a lifting plate upward. When the lifting plate moves upward, it loses its fixation to the protective netting, making it easier for personnel to replace the netting. After replacement, the lifting plate automatically moves downward using the elasticity of a second spring, thus automatically fixing the protective netting in place. This achieves the effect of facilitating the replacement of the protective netting. At the same time, the rotating shaft can be rotated according to the slope of the slope, and the rotating shaft drives the first and second fixing blocks to rotate, making the protective netting fit the slope more closely.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a slope protection mechanism for water conservancy and hydropower projects, including a fixed frame 1, one end of the fixed frame 1 being rotatably connected to the outer wall of the rotating shaft 2, and a protective net fixing mechanism 4 being fixedly connected to the outer wall of the rotating shaft 2;

[0023] The protective net fixing mechanism 4 includes a first fixing block 41, a sliding groove 42, a second fixing block 43, a second spring 45, a lifting plate 46, and a pull rod 47. One end of the first fixing block 41 is fixedly connected to the outer wall of the rotating shaft 2. The sliding groove 42 is opened at one end of the outer wall of the rotating shaft 2. The outer wall of one end of the second fixing block 43 is engaged with the inner cavity of the sliding groove 42. The upper end of the second spring 45 is fixedly connected to the upper end of the inner cavity of the first fixing block 41 and the second fixing block 43. The upper end of the lifting plate 46 is fixedly connected to the lower end of the second spring 45. The lower end face of the lifting plate 46 overlaps with the upper end face of the protective net 5, and the lower end face of the protective net 5 overlaps with the inner cavity of the first fixing block 41 and the second fixing block 43. The outer wall of the pull rod 47 is engaged with the inner wall of the first fixing block 41 and the second fixing block 43, and is rotatably connected to the upper end face of the lifting plate 46.

[0024] By pulling the lever 47, the lever 47 moves upward, which in turn moves the lifting plate 46 upward. When the lifting plate 46 moves upward, it loses its fixation to the protective netting 5, making it easier for personnel to replace the protective netting 5. After replacement, the lifting plate 46 automatically moves downward using the elastic force of the second spring 45, thus automatically fixing the protective netting 5. This achieves the effect of facilitating the replacement of the protective netting 5. At the same time, the rotating shaft 2 can be rotated according to the slope of the slope, and the rotating shaft 2 drives the first fixing block 41 and the second fixing block 43 to rotate, so that the protective netting 5 fits the slope better. The second fixing block 43 can also move in the inner cavity of the chute 42, so as to adjust according to the length of the slope, thereby achieving the effect of saving the protective netting 5.

[0025] Specifically, the protective net fixing mechanism 4 includes a screw 44, one end of which is rotatably connected to one end of the inner cavity of the slide groove 42, and the outer wall of the screw 44 is threadedly connected to the inner cavity of one end of the second fixing block 43, and a knob is installed on one end of the screw 44.

[0026] By rotating the screw 44, the second fixed block 43 can be moved within the cavity of the slide 42, allowing personnel to easily adjust it according to the length of the slope, thus achieving the effect of saving protective netting 5.

[0027] Specifically, the lifting plate 46 and the inner cavity of the first fixing block 41 and the second fixing block 43 are equipped with racks, and the racks overlap with the outer wall of the protective net 5.

[0028] The installation of the rack and pinion mechanism improves the fixation of the lifting plate 46 to the protective net 5.

[0029] Specifically, a position fixing mechanism 3 is provided on the outer wall of one end of the rotating shaft 2;

[0030] The position fixing mechanism 3 includes a groove 31, a fixing plate 32, a first spring 33, and a fixing rod 34. The groove 31 is formed on the outer wall of one side of the rotating shaft 2. One end of the fixing plate 32 is fixedly connected to one end of the fixing frame 1. The upper end of the first spring 33 is fixedly connected to the lower end face of the fixing plate 32. The outer wall of the fixing rod 34 penetrates the inner wall of the fixing plate 32 and is engaged with the inner cavity of the groove 31. A limit plate is installed on the outer wall of the fixing rod 34, and the upper end of the limit plate is fixedly connected to the lower end of the first spring 33.

[0031] By pulling the fixing rod 34, the fixing rod 34 is moved upward, thereby causing the fixing rod 34 to lose its inner cavity of the groove 31, which makes it convenient for personnel to rotate the rotating shaft 2. The rotating shaft 2 can be rotated according to the slope of the slope, and the rotating shaft 2 drives the first fixing block 41 and the second fixing block 43 to rotate, thereby making the protective net 5 fit the slope more closely.

[0032] Specifically, the inner cavity of the slide 42 is rectangular and engages with the outer wall of one end of the second fixing block 43.

[0033] By engaging the rectangular groove 42 with the second fixing block 43, the second fixing block 43 can be prevented from dislodging from the inner cavity of the groove 42, while also allowing the second fixing block 43 to move horizontally during movement.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
