Description

Technical Field

[0001] The present invention relates to the technical field of desert control devices, and specifically to a sand fixation and water conservation device for soil and water conservation. Background Art

[0002] Desertification and drought are one of the main environmental problems faced by the world today. Wind erosion and soil and water loss in desert areas are severe, leading to the deterioration of the ecological environment and the decline of land productivity, which have a great impact on the lives of local residents and agricultural production. In order to contain the spread of desertification and improve the water use efficiency of land, the research and development of sand fixation and water conservation technologies are particularly important;

[0003] After investigation, the publication (announcement) number; CN107820909B discloses a sand fixation and water conservation device. This technology discloses "a container in the shape of a cone with an upper opening and a lower opening. The inside of the container is divided into a counterweight layer, a heat insulation layer, and a water conservation layer from top to bottom. An outwardly extending and obliquely upward water collecting groove is provided around the outer side wall of the container. A number of water passing holes are provided around the side wall of the container in the water collecting area of the water collecting groove. A rainwater channel connected to the water passing holes and leading to the water conservation layer is provided inside the container and other technical solutions. Under the action of its own gravity of the counterweight, the bottom of the device is tightly pressed against the desert surface, achieving the effect of sand fixation; at the same time, the upper end of the device is open and a water collecting groove is provided on the outer side wall, which facilitates the collection of rainwater, and the conical container also facilitates the condensed water on the side wall of the container to flow back to the bottom of the container; since the lower end of the device is open, the collected water can directly enter the desert surface through the water conservation layer and other technical effects";

[0004] Although the above device can receive rainwater through the upper opening, the water collecting groove is prone to intrusion of sand over a long time and accumulates in the water collecting groove, affecting the water collection effect. At the same time, due to the small precipitation in desert areas and the upper opening of the above device being in an open state, the water inside the device will still evaporate under long-term sunlight. Therefore, its water conservation effect is not good and its applicability is low. So we propose a sand fixation and water conservation device for soil and water conservation to solve the above existing problems. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1-6 shown:

[0038] A sand-fixing and water-retaining device for soil and water conservation, including a frame 101, an inclined surface 110 is provided on the upper surface of the frame 101, and the inclined surface 110 is inclined downward from the outside to the inside;

[0039] Bolts 102, four groups are provided and are respectively arranged at the four corners of the frame 101. Circular holes are opened at the four corners of the frame 101, and the bolts 102 are fixed at the circular holes opened in the frame 101. The bottom end of the bolt 102 is designed with a conical structure;

[0040] The first frustum-shaped housing 103 is fixedly installed on the inner side wall of the frame 101;

[0041] The second frustum-shaped housing 104 is arranged below the first frustum-shaped housing 103 and is fixedly connected to the inner side wall of the frame 101;

[0042] Multiple groups of drain outlets 105 are provided and are opened at the edge of the second frustum-shaped housing 104;

[0043] The baffle 106 is arranged inside the frame 101, and the upper surface of the baffle 106 is fixedly connected to the bottom side wall of the second frustum-shaped housing 104;

[0044] The water retention layer 107 is fixedly installed between the frame 101 and the baffle 106, and the water retention layer 107 is composed of sponge and synthetic fiber materials;

[0045] Two groups of geotextiles 109 are provided and are respectively fixed at the openings between the first frustum-shaped housing 103 and the second frustum-shaped housing 104;

[0046] Two groups of sealing strips 108 are provided and are respectively fixed at the openings between the first frustum-shaped housing 103 and the second frustum-shaped housing 104. The two groups of sealing strips 108 and the two groups of geotextiles 109 together form a square frame;

[0047] The first frustum-shaped housing 103, the second frustum-shaped housing 104 and the frame 101 form a first water storage cavity 111, and the second frustum-shaped housing 104, the frame 101, the water retention layer 107 and the baffle 106 form a second water storage cavity 112;

[0048] A cleaning member 2 for cleaning the geotextile 109 is installed on the frame 101. The cleaning member 2 includes two groups of brush rods 201 rotatably installed on the frame 101 near the geotextile 109 through bearings. At the mutually remote ends of the two groups of brush rods 201, fan wheels 202 are fixedly installed. The brushes of the brush rods 201 are in contact with the geotextile 109 and the first frustum-shaped housing 103.

[0049] In this implementation scheme: When the soil and water conservation and sand fixation and water retention device is in use, the frame 101 is inserted into the sand by means of the bolt 102 to fix the frame 101 and carry out sand fixation operations. The space inside the frame 101 can be used to plant green plants to resist wind erosion. It is particularly suitable for desertified and arid regions. This structure helps to reduce the occurrence of sandstorms and protect the surrounding environment from sand and wind damage. The frame 101 provides a relatively stable growth environment for green plants, reduces the damage to plant roots caused by the fluidity of sandy soil, thereby improving the survival rate and growth rate of plants. At the same time, with the help of the roots of green plants, the sand fixation effect is further enhanced;

[0050] When the bolt 102 penetrates deep into the inner layer of the desert, the lower surface of the frame 101 is in close contact with the desert surface, and the water retention layer 107 also fits the desert surface;

[0051] When the rainy season comes, rainwater falls on the first frustum-shaped shell 103. Due to the inclined structure of the first frustum-shaped shell 103, the rainwater will be guided to the position of the geotextile 109. At the same time, an inclined surface 110 is provided on the upper surface of the frame 101, which increases the guiding area of the rainwater. The geotextile 109 has water permeability, and the rainwater can penetrate through the geotextile 109 and be discharged into the first water storage cavity 111. Subsequently, the rainwater passes through the drain port 105 of the second frustum-shaped shell 104 and then is discharged into the second water storage cavity 112. The water retention layer 107 is composed of sponge and synthetic fiber materials, which can absorb and retain a certain amount of water, and at the same time allow the water to pass through at a slower speed. The water retention layer 107 can slow down the speed of water seeping from the second water storage cavity 112 into the sand, prevent the rapid loss of water. In this way, the water can be more evenly distributed in the sand, avoiding the situation of local over-wet or over-dry, helping the sand to maintain a certain humidity, being beneficial to the absorption and retention of water by the sand, thereby enhancing the water retention capacity of the sand. Part of the rainwater will gather in the middle of the frame 101, which can irrigate the green plants inside the frame 101;

[0052] As Figure 5 shown, an inclined plate 307 is provided inside the bolt 102. The inclined plate 307 is designed with an inclined structure, which can more effectively guide the water flow. For the back surface of the inclined plate 307, when the sand inside the bolt 102 needs to be discharged from the sand inlet 113 in the later stage, the back surface side of the inclined plate 307 can play a role in guiding the sand, making the inclined plate 307 have a dual function;

[0053] The rainwater enters the first water storage cavity 111 through the geotextile 109. As a filtering material, the geotextile 109 has good water permeability and filtering performance. It can allow the water to pass through while preventing sand and other larger particulate matters from passing through. The combined use of the geotextile 109 and the sealing strip 108 can ensure that the rainwater passes through while the sand is blocked, thereby preventing the sand from entering the first water storage cavity 111 and the second water storage cavity 112. Such a design can more effectively collect rainwater, increase the storage capacity of rainwater, and ensure the water retention effect of the sandy soil;

[0054] At the same time, the synergistic effect of the first frustum-shaped shell 103, the sealing strip 108 and the geotextile 109 can also play a role in shading, effectively reducing the evaporation rate of water and improving the water retention efficiency. Even in desert areas with less precipitation, this system can achieve efficient water collection and preservation;

[0055] In a wind environment, the fan wheel 202 can be driven to rotate. The fan wheel 202 drives the brush rod 201 to rotate. The brush on the brush rod 201 contacts the surface of the geotextile 109 and the first frustum-shaped housing 103, and can sweep away the sand remaining on these surfaces, maintaining the cleanliness of the geotextile 109, thereby improving the water permeability effect of the geotextile 109 and the use effect of the entire device, meeting the actual use requirements.

[0056] It should be noted that: at the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0057] Furthermore;

[0058] In an alternative embodiment, a sand inlet 113 is provided on the surface of the plug 102. The plug 102 is designed with a hollow open structure. A dredging and anti-blocking mechanism 3 for dredging the sand inlet 113 is installed on the plug 102. The dredging and anti-blocking mechanism 3 includes a pressing cover plate 301 arranged at the open end of the plug 102 and a guide hook 305 fixed to the bottom end of the pressing cover plate 301. One end of the guide hook 305 is located at the position of the sand inlet 113 of the plug 102. A partition plate 303 is arranged below the pressing cover plate 301. The partition plate 303 is fixed to the inner side wall of the plug 102. The partition plate 303 is provided with a moving hole adapted to the guide hook 305. The guide hook 305 and the partition plate 303 are slidably connected through this moving hole. A spring 302 is wound around the surface of the guide hook 305. The two ends of the spring 302 are respectively fixed to the pressing cover plate 301 and the partition plate 303. A limiting strip 304 is fixed to the inner side wall of the plug 102. A limiting groove adapted to the limiting strip 304 is provided on the edge surface of the pressing cover plate 301. The pressing cover plate 301 can slide on the limiting strip 304 through the provided limiting groove;

[0059] A sealing gasket 306 is fixed to the outer surface of the pressing cover plate 301. The sealing performance between the pressing cover plate 301 and the plug 102 is increased through the sealing gasket 306. An inclined plate 307 is fixed at a position inside the plug 102 near the sand inlet 113. A sliding hole adapted to the guide hook 305 is provided on the inclined plate 307. The guide hook 305 can slide in the sliding hole provided on the inclined plate 307;

[0060] The plug 102, the inclined plate 307 and the partition plate 303 form a third water storage cavity. The plug 102 is provided with a second diversion hole 309 at the top of the third water storage cavity, and the plug 102 is provided with a first diversion hole 308 at the bottom of the third water storage cavity. The frame 101 is provided with a water inlet hole communicating with the second diversion hole 309, and the frame 101 is also provided with a drain hole communicating with the first diversion hole 308. The water inlet hole and the drain hole are both communicated with the second water storage cavity 112.

[0061] In this embodiment: The sand inlet 113 provided on the bolt 102 is exposed. Then, the sand is pushed towards the position of the sand inlet 113, so that the sand accumulates at the sand inlet 113 and enters the inner cavity of the bolt 102 through this opening;

[0062] During the process of pushing the sand, the pressing cover plate 301 is simultaneously pressed, causing it to slide within the bolt 102 and guiding the guide hook 305 to move downward, thereby compressing the spring 302. The guide hook 305 slides on the partition plate 303. By pressing or releasing the pressing cover plate 301, under the synergistic action of the spring 302, the guide hook 305 can move up and down. When one end of the guide hook 305 moves at the sand inlet 113, it can effectively reduce the blockage that occurs when the sand enters, thereby improving the efficiency of the sand entering the bolt 102;

[0063] During the process of pressing the pressing cover plate 301, the pressing cover plate 301 can slide on the limiting strip 304 through the provided limiting groove, thereby positioning the pressing cover plate 301 to ensure that the guide hook 305 corresponds to the sand inlet 113;

[0064] As the sand continuously fills the inside of the bolt 102, the weight of the sand increases the overall stability, making the frame 101 more firmly fixed in the sandy soil, thereby improving the ability to resist wind erosion. The hollow structure of the bolt 102 reduces the material usage and lowers the production cost. In addition, using the on-site sand as the filling material further saves transportation and material costs;

[0065] When the water volume in the second water storage cavity 112 is full, the excess water can flow into the third water storage cavity (not shown in the figure) through the water inlet hole and the second diversion hole 309. This can increase the water storage capacity and extend the water retention time for the sandy soil. At the same time, through the first diversion hole 308 and the drain hole, the water can be discharged into the second water storage cavity 112.

[0066] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
