Description

Technical Field

[0001] The utility model relates to the technical field of soil and water loss control, in particular to a soil and water loss prevention device for soil and water conservation. Background Art

[0002] Soil and water conservation is an important means to maintain the ecological environment and ensure the sustainable development of agriculture. Preventing soil and water loss has become an urgent task. At present, we mainly adopt two methods, comprehensive management and chemical management, to deal with this problem. Among them, comprehensive management has been widely used in practice due to its comprehensiveness and sustainability. This method covers many aspects such as vegetation restoration, slope management, and channel management. Especially in the slope management on both sides of the river, its importance is self-evident.

[0003] However, existing slope protection devices have exposed some problems in practical applications. At present, most devices use a whole piece of protective net directly laid on the slope. Although this method seems simple and effective in the early stage, its disadvantages gradually become apparent over time. The long-term erosion of rainwater not only weakens the stability of the protective net, but also accelerates its aging process. In addition, the activities of wild animals such as birds often cause partial damage to the protective net. Once these damages occur, the prevention and control effects are often greatly reduced, or even completely fail in some areas.

[0004] What is even more troublesome is that once the protective net is damaged, the operation of disassembling and replacing the entire piece is not only cumbersome but also costly. This not only increases the difficulty and cost of maintenance, but also affects the sustainability and efficiency of prevention and control work. Therefore, developing a more advanced, durable and easy-to-maintain device to prevent soil and water loss has become an urgent problem to be solved. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution for a device for preventing soil and water loss for soil and water conservation:

[0024] according to Figure 1-5As shown, the soil and water conservation device for preventing soil and water loss comprises a first locking frame 1, a plurality of positioning shafts 4 are evenly fixedly connected to the upper surface of the first locking frame 1, and a protective net 5 is assembled on the upper surface through the positioning shafts 4, an A support ear 2 is fixedly connected in the middle of the left side wall, a B support ear 3 is fixedly connected to the front and rear ends of the right side wall, an A support ear 2 is fixedly connected in the middle of the front side wall, a B support ear 3 is fixedly connected to the front and rear ends of the rear side wall, a positioning hole 11 is correspondingly provided on the plurality of positioning shafts 4, and the positioning holes 11 are evenly provided on the second locking frame 8, a C support ear 9 is fixedly connected to the front and rear ends of the left side wall of the second locking frame 8, a D support ear 10 is fixedly connected in the middle of the right side wall, a C support ear 9 is fixedly connected to the front and rear ends of the front side wall, a D support ear 10 is fixedly connected in the middle of the rear side wall, and the A support ear 2, the B support ear 3, the C support ear 9, and the D support ear 10 are all fixedly connected. A locking hole 12 of the same size is provided, and a locking bolt 13 is installed in the locking hole 12. The protective net 5 is composed of a edging 6 and a protective blanket 7. A plurality of circular holes are opened on the edging 6 and it is movably mounted on the positioning shaft 4. A protective blanket 7 is sewn on the inner edge, so that the protective net 5 is clamped more firmly in the first locking frame 1 and the second locking frame 8 and is not easily damaged. The protective blanket 7 has two layers, and vegetation seeds are evenly wrapped in the middle to prevent the seeds from being washed away by water and are easier to take root in the soil, thereby promoting the prevention and control of soil erosion. The locking bolt 13 is composed of a connecting rod 14, a threaded rod 15 and a hexagonal head 16. The connecting rod 14 passes through the locking hole 12, and a threaded hole is opened at the upper end, and the threaded rod 15 is threadedly connected. The top of the threaded rod 15 is fixed with a hexagonal head 16. The sizes of the A ear 2, the B ear 3, the C ear 9 and the D ear 10 are all the same.

[0025] During specific use, the protective net is placed on the first locking frame through the positioning shaft, and then the second locking frame is placed on the first locking frame through the positioning hole. At this time, the A ear and the two C ears form a "concave" cross-section, and the D ear and the two B ears form a "convex" cross-section, thus forming a locking unit. When four more locking units are placed around, the "concave" and "convex" are spliced ​​together, and then the locking bolts are inserted to lock multiple locking units together. When the protective net of a locking unit is damaged, the second locking frame can be removed by loosening the locking bolts, and a new protective net can be replaced. When the entire locking unit needs to be replaced, the second locking frames around the locking unit can be removed, and the first locking frame of the locking unit can be taken out, and then a new locking unit can be replaced. The operation is simple, maintenance costs are reduced, and the continuity and efficiency of prevention and control work are improved.
