Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, and more specifically, it relates to a slope protection net for agricultural water conservancy projects. Background Art

[0002] With the development and progress of modern agriculture, the construction of supporting agricultural water conservancy projects has also been implemented and promoted. Slope protection tools in water conservancy projects refer to the general term for various paving and planting on the slope surface to prevent the slope from being eroded. Now, after the slope protection construction is completed, in order to reinforce and protect the slope, slope protection nets are usually laid and installed on the outside of the slope.

[0003] A search revealed, for example, patent CN213173561 U, which discloses a slope protection net for water conservancy projects, relating to the field of slope protection construction. It includes a slope protection net body, fixing rods, and fixing components. The slope protection net body comprises a protective net and an installation frame. The protective net is disposed within the installation frame. Multiple slope protection net bodies are spliced ​​together to form the slope protection net. Multiple fixing rods are provided, spaced apart on the lower surface of the installation frame. Adjacent installation frames are fastened together, and the intersections of four installation frames arranged in a grid pattern are detachably connected by the fixing components. This application has the advantage of allowing for partial replacement of the slope protection net based on its damage condition, thus saving materials.

[0004] The slope protection netting described in the aforementioned patent still has the following shortcomings:

[0005] In the practical application of slope protection netting, a special fixing structure is usually used to wedge into the ground to secure the netting. However, during long-term use, the fixing structure may loosen due to various external influences. Currently, it is difficult to effectively remind maintenance personnel when the netting fixing structure becomes loose, which may lead to workers neglecting to notice the loosening during maintenance. This can result in the netting falling off during subsequent use, which is detrimental to reducing safety hazards during the use of the netting. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a protective net for the slope protection of dams in agricultural water conservancy projects. This addresses the issue mentioned in the background section where the fixed structure may loosen due to various external influences during prolonged use. Furthermore, current protective net fixing structures often fail to effectively alert maintenance personnel when loosening occurs, leading to negligence during maintenance and increasing the risk of the net falling off during subsequent use. This, in turn, hinders efforts to reduce safety hazards during the use of the protective net.

[0007] The purpose and effectiveness of this utility model of a protective net for the slope protection of agricultural water conservancy engineering embankments are achieved by the following specific technical means:

[0008] A protective net for the slope protection of an agricultural water conservancy dam includes: a fixing base; the fixing base adopts a rectangular block structure, and a rectangular cavity structure is opened in the middle of the fixing base. The top of the fixing base has four sets of through circular slot structures in a rectangular array. A cylindrical top rod is rotatably installed in the middle of the top of the fixing base. Four sets of air scoops are fixedly installed on the outer side of the top of the top rod. The air scoops adopt a hollow hemispherical structure and are fixedly installed in a ring array on the outer side of the top rod. A set of cylindrical striking rods is fixedly installed on both sides of the top rod. A set of cylindrical detection rods is slidably installed in each of the four sets of circular slots on the top of the fixing base. There are four sets of detection rods in total, and a spring structure is sleeved on the outer side of the bottom of the detection rod. A bell is suspended on one side of the top of the detection rod.

[0009] Furthermore, a tapered fixed cone is fixedly installed at the bottom center of the fixed base; four sets of take-up rollers are rotatably arranged in a rectangular array inside the rectangular cavity in the middle of the fixed base.

[0010] Furthermore, each of the four sets of take-up rollers is fixedly equipped with a set of T-shaped operating rods, and the top of the operating rods extends to the top of the fixed base; an inner ratchet is fixedly equipped on the outer side of the operating rod, and an arc-shaped groove structure is formed on the outer side of the inner ratchet; a cylindrical sliding rod is fixedly equipped in the arc-shaped groove of the inner ratchet, and a spring is sleeved on the outer side of the sliding rod; a wedge-shaped ratchet tooth is slidably equipped on the outer side of the sliding rod, and a spring is provided between the ratchet tooth and the inner ratchet; four sets of annular outer ratchets are fixedly equipped in a rectangular array on the top of the fixed base, and four sets of inner ratchets are respectively located on the inner side of the four sets of outer ratchets.

[0011] Furthermore, a set of connecting ropes is wound and connected to the outer side of each of the four sets of winding rollers; a protective net is fixedly connected to one end of the connecting rope, and a set of connecting ropes is fixedly connected to the outer side of each of the four corners of the protective net.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this application, after the fixed base becomes loose from the ground, each set of detection rods slides synchronously along the fixed base, thereby causing the bell to shift. When the loosening reaches a certain degree, the bell can move to the same height as the striking rod. At this point, when the wind causes the top rod and striking rod to rotate, they can collide with the bell and produce a sound. When staff are performing maintenance, this effectively reminds them, allowing them to more promptly and accurately identify the loose areas and take appropriate action, greatly improving the maintenance efficiency of the staff. At the same time, it can also effectively monitor the overall usage and reduce the occurrence of accidents.

[0014] During installation, the protective net is fixed with mounting brackets. This allows for flexible adjustment of the tightness between the net and the ground according to terrain conditions. It also facilitates the setting of a corresponding number of mounting brackets based on the number of net sections and makes adjustments according to the protected area, thus greatly improving the flexibility and ease of use of the device.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1:

[0025] As attached Figure 1 To the attached Figure 6 As shown:

[0026] This utility model provides a protective net for the slope protection of an agricultural water conservancy project dam, comprising: a fixing base 1; the fixing base 1 adopts a rectangular block structure, and a rectangular cavity structure is opened in the middle of the fixing base 1; the top of the fixing base 1 has four sets of through circular slot structures in a rectangular array; a cylindrical top rod 108 is rotatably installed in the middle of the top of the fixing base 1; four sets of air scoops 109 are fixedly installed on the outer side of the top of the top rod 108, the air scoops 109 adopt an internally hollow hemispherical structure, and the air scoops 109 are fixedly installed in a ring array on the outer side of the top rod 108; a set of cylindrical striking rods 110 are fixedly installed on both sides of the top rod 108; a set of cylindrical detection rods 2 are slidably installed in each of the four sets of circular slots on the top of the fixing base 1; a total of four sets of detection rods 2 are provided, and a spring structure is sleeved on the outer side of the bottom of the detection rods 2; a bell 201 is suspended on one side of the top of the detection rod 2.

[0027] The fixed base 1 has a fixed cone 101 with a conical structure fixed in the middle of its bottom; four sets of take-up rollers 102 are arranged in a rectangular array in the rectangular cavity in the middle of the fixed base 1.

[0028] The specific usage and function of this embodiment are as follows:

[0029] By wedging the fixing cone 101 into the ground, the fixing seat 1 is fixed, ensuring that the bottom surface of the fixing seat 1 is in close contact with the ground. Under the pressure of the ground, each set of detection rods 2 can be pushed to slide upwards along the circular grooves on the top of the fixing seat 1, causing the bell 201 to move to its highest point. At this point, the bell 201 will not contact the striking rod 110. During the use of the fixing seat 1, if the fixing seat 1 and fixing cone 101 become loose due to external influences or other factors, the bottom surface of the fixing seat 1 will first become loose and exposed to the ground. As the distance between them increases, the bottom of the detection rod 2 remains in close contact with the ground due to the action of the spring on the outside of the detection rod 2. At this time, the detection rod 2 will slide down along the circular groove of the fixed base 1, thereby lowering the height of each set of bells 201. When the wind drives the wind scoop 109 and the top rod 108 to rotate, it will simultaneously drive the striking rod 110 to rotate and contact one or more sets of bells 201, producing a loud sound. During later maintenance, this can remind the staff on site, making it easier for them to find and handle the problem.

[0030] Example 2:

[0031] Based on Example 1, as shown in the appendix Figure 1 To the attached Figure 6 As shown:

[0032] Each of the four sets of take-up rollers 102 has a set of T-shaped operating rods 103 fixedly installed on its top, and the top of the operating rods 103 extends to the top of the fixed base 1; an inner ratchet 104 is fixedly installed on the outer side of the operating rods 103, and an arc-shaped groove structure is opened on the outer side of the inner ratchet 104; a cylindrical slide rod 105 is fixedly installed in the arc-shaped groove of the inner ratchet 104, and a spring is sleeved on the outer side of the slide rod 105; a wedge-shaped ratchet 106 is slidably installed on the outer side of the slide rod 105, and a spring is installed between the ratchet 106 and the inner ratchet 104; four sets of annular outer ratchet 107 are fixedly installed in a rectangular array on the top of the fixed base 1, and the four sets of inner ratchet 104 are respectively installed on the inner side of the four sets of outer ratchet 107.

[0033] Among them, a set of connecting ropes 111 are wound and connected to the outer side of each of the four sets of winding rollers 102; a protective net 112 is fixedly connected to one end of the connecting rope 111, and a set of connecting ropes 111 are fixedly connected to the outer side of each of the four corners of the protective net 112.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, during use, the protective net 112 is first laid in the protected area, and the four corners of the protective net 112 are respectively connected to four sets of winding rollers 102 by four sets of connecting ropes 111. After the protective net 112 is laid, a set of fixing seats 1 connected to each set of winding rollers 102 is inserted into the ground around the protective net 112 for fixation. Then, the winding rollers 102 can be rotated by rotating the operating lever 103, thereby winding and tightening the connecting ropes 111. Through the cooperation of the four sets of winding rollers 102, the middle set of protective net 112 can be tightened and fixed, and the tightness of the protective net 112 can be selected according to the actual terrain conditions, facilitating... When used under different terrain protrusions, during the rotation of the take-up roller 102 via the operating lever 103, the inner ratchet 104 and ratchet 106 are simultaneously rotated inside the outer ratchet 107. Through the cooperation of the ratchet 106 and the outer ratchet 107, the reverse rotation of the operating lever 103 and the take-up roller 102 can be avoided, thereby ensuring the stability of the tightness adjustment of the protective net 112. When reverse rotation is required, the ratchet 106 can be slid upward along the slide bar 105, so that the ratchet 106 is disengaged from the inner box of the outer ratchet 107, and the operating lever 103 and the take-up roller 102 can be rotated in the opposite direction to complete the entire installation and adjustment process of the protective net 112.
