Description

Technical Field

[0001] This utility model relates to the field of plateau afforestation technology, and in particular to a sand-prevention device for plateau afforestation suitable for special climates. Background Technology

[0002] In the global process of ecological protection and restoration, the ecological governance of plateau sandy areas has always been an extremely challenging issue. Plateau regions in my country, such as the Qinghai Lake sandy area and the edge of the Qinghai-Tibet Plateau, generally exceed 3,000 meters in altitude, belonging to typical high-altitude and cold zones. They not only suffer from thin air, strong winds, and frigid weather, but also face multiple natural constraints such as thin soil layers, strong ultraviolet radiation, and low ground temperatures. The combination of these unique climatic and geographical conditions makes plateau sandy areas vulnerable regions within the ecosystem, with severe desertification posing a serious threat to the surrounding ecological environment and human production and lives.

[0003] Afforestation, as one of the core means of sand control in plateau sandy areas, faces key bottlenecks in seedling survival and stable growth. First, frequent strong winds, with wind speeds reaching tens of meters per second, not only make it difficult for seedlings to take root but also accelerate surface water evaporation, exacerbating drought. Second, water resources are extremely scarce, with sparse and unevenly distributed rainfall, while traditional irrigation methods are difficult to implement due to terrain limitations, resulting in extremely high irrigation costs per unit area. Third, the soil has poor water and fertilizer retention capacity, and the thin soil layer cannot effectively store water, making seedling roots prone to withering due to lack of water and fertilizer, thus leading to a low survival rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sand-control device for high-altitude afforestation suitable for special climates.

[0015] As a further description of the above technical solution: the fixing component includes:

[0016] The slot is located on the support frame;

[0017] The fixing bolt is threaded through the main body and is used to fix the support frame after it is moved. One end of the fixing bolt is engaged in the slot.

[0018] As a further description of the above technical solution: the slots are provided in several groups, and every two groups of the slots are provided on one side of the support frame and arranged vertically.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1:

[0039] For reference Figures 1 to 5 This utility model provides a sand control device for high-altitude afforestation suitable for special climates. The main body 1 is used to support components; the water collection mechanism includes a net 203 arranged in the main body 1, which is used to condense the morning mist into water droplets; the water collection mechanism is also provided with a fixing component, which is used to fix the net 203 after it is unfolded or retracted.

[0040] It should also be understood that the mesh 203 is treated with hydrophilic polymer materials or nano-coatings to enhance the water mist adsorption and condensation efficiency. The pore size of the mesh 203 is designed to be 0.5-1mm, which ensures that water mist can pass through while preventing sand particles from penetrating. Micro-grooves are set on the surface of the mesh 203 to increase the condensate collection area. The back of the mesh 203 is a phase change material (such as paraffin wax), which actively cools down in the low temperature environment at night to accelerate water mist condensation.

[0041] In a preferred embodiment, the water collection mechanism further includes: a support frame 201, slidably connected to the main body 1, for moving the mesh 203, with the upper end of the mesh 203 fixedly arranged on the support frame 201; a drum 202, rotatably connected inside the main body 1, for winding the mesh 203, with the other end of the mesh 203 fixedly arranged on the drum 202; a torsion spring 204, with one end fixedly arranged on one side of the drum 202 and the other end fixedly arranged on the main body 1; and a collection trough 205, opened at the lower end inside the main body 1, for collecting condensed water and transferring it to the roots of the seedlings.

[0042] The collection trough 205 is located below the roller 202. Water droplets condensed on the mesh 203 flow through the mesh 203 onto the roller 202 and fall into the collection trough 205. The water then flows to the roots of the seedlings for irrigation due to the inclined bottom of the collection trough 205.

[0043] In a preferred embodiment, the mesh fabric 203 is provided in four groups, and the mesh fabric 203 is provided on the four sides of the main body 1.

[0044] In a preferred embodiment, the fixing component includes: a slot 206 formed on the support frame 201; and a fixing bolt 207 threadedly connected to the main body 1 for fixing the moved support frame 201, with one end of the fixing bolt 207 engaged in the slot 206.

[0045] It should be noted that there are four sets of fixing bolts 207, with each pair of fixing bolts 207 symmetrically arranged on both sides of the main body 1.

[0046] In a preferred embodiment, the slots 206 are provided in several groups, with each two groups of slots 206 located on one side of the support frame 201 and arranged vertically. The upper slot 206 serves as a limit for the support frame 201 after it is retracted, and the lower slot 206 serves as a limit for the support frame 201 after it is unfolded.

[0047] Example 2:

[0048] Based on Embodiment 1, in order to further improve the stability of the main body 1, a limiting structure is provided on the main body 1;

[0049] As a preferred embodiment, the limiting structure includes a ground nail 302 disposed on one side of the main body 1 for fixing the main body 1 to the ground.

[0050] It should be noted that the upper end of the ground stake 302 is designed with barbed teeth, which increases the friction of the ground stake 302 when it is inserted into the sand, thereby improving the stability of the main body 1.

[0051] In a preferred embodiment, the limiting structure further includes: a housing 301, fixedly arranged on one side of the main body 1, for housing the ground nail 302, and the lower end of the ground nail 302 is rotatably connected to the housing 301; a limiting hole 303, formed on one side of one end of the ground nail 302; and a limiting bolt 304, threadedly connected to the housing 301, for fixing the ground nail 302, and one end of the limiting bolt 304 is engaged in the limiting hole 303.

[0052] In a preferred embodiment, the ground nail 302 is provided in four sets, and each set of ground nail 302 is provided with two sets of limiting holes 303. The limiting holes 303 are symmetrically arranged at one end of the ground nail 302 at 180 degrees.

[0053] Working principle: When in use, first move this device to the sapling planting location in the sand. After the sapling is planted, turn the limiting bolt 304. The limiting bolt 304 moves to one side through the threaded connection on the outer shell 301. When one end of the limiting bolt 304 is disengaged from the limiting hole 303, turn the ground nail 302 to rotate on the outer shell 301. After all four sets of ground nails 302 have been adjusted, turn the limiting bolt 304 in the opposite direction. When one end of the limiting bolt 304 is re-engaged on the corresponding limiting hole 303, the fixing is completed. Then, put the main body 1 on the sapling planting site and insert the four sets of ground nails 302 into the sand. The barbed teeth on the upper end of the ground nail 302 make the main body 1 firmly fixed on the sand. When not in use, the ground nails 302 can be stored back into the outer shell 301, reducing the space occupied.

[0054] Then, the four sets of fixing bolts 207 are turned in sequence. The fixing bolts 207 move to one side on the main body 1 through the threaded connection. When one end of the fixing bolt 207 disengages from the slot 206, the support frame 201 is pulled upward by the handle on the support frame 201. The support frame 201 simultaneously drives the four sets of mesh fabric 203 to extend. The extension of the mesh fabric 203 causes the drum 202 to rotate on the main body 1 and torsion spring 204 to twist. After the support frame 201 moves to a certain height, the fixing bolts 207 are turned in the opposite direction. One end of the fixing bolt 207 is engaged with the lower end. The extended support frame 201 is fixed in the slot 206. The water mist in the early morning of the plateau is collected by four sets of extended nets 203. The collected water mist is condensed into water droplets by the temperature difference between day and night. The condensed water droplets flow through the nets 203 onto the roller 202 and drip into the collection trough 205. The water then drips around the roots of the planted seedlings. By converting water mist into water droplets, the seedlings are irrigated, reducing manual irrigation and water consumption, and improving the survival rate of the seedlings and their resistance to wind and sand movement.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
