Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 10, the present invention provides a desert greening treatment system, which comprises a settling tank 100, a water reservoir 200, a water pipe 300 and a drip irrigation pipe 400; the water reservoir 200 is connected with the sedimentation tank 100, the water pipe 300 is connected with the water reservoir 200 through a water pump (not shown), the water pipe 300 is provided with a plurality of water conveying branch pipes 301, the water conveying branch pipes 301 are connected with drip irrigation pipes 400, the drip irrigation pipes 400 are buried under the soil layer, and the drip irrigation pipes 400 have an anti-blocking function.

The sedimentation tank 100 is used for draining water in a river, the water flowing in the river flows into the sedimentation tank 100 through a water channel, sediment is obtained in the sedimentation tank 100 due to the sediment contained in the water, and the water on the upper layer of the sedimentation tank 100 is conveyed to the water storage tank 200 through a pipeline for storage. Wherein, in order to improve the life of water pump, can also increase silt filter between sedimentation tank 100 and cistern 200 to the silt that water mix with in the cistern 200 is got into in more effective filtration. When irrigation water supply for plants is needed, water in the reservoir 200 is output through the water pump, and flows into each water delivery branch pipe 301 through the water delivery pipe 300, and finally drip irrigation is performed on the plants through the drip irrigation pipe 400.

In addition, in order to meet the anti-blocking requirement of burying water supply in the drip irrigation pipe 400 in the desert region, the drip irrigation pipe 400 adopts a drip irrigation pipe with an anti-blocking function, and comprises a water supply pipe 1, a cylindrical dripper 2 and an elastic sleeve 3, wherein the water supply pipe 1 is connected with the water delivery branch pipe 301; offer the delivery port 11 that matches with cylindrical water dropper 2 on the delivery pipe 1, the both ends mouth of cylindrical water dropper 2 is provided with first inner chamfer 24 respectively, the cylindrical water dropper is provided with and runs through the apopore 22 of the pipe wall of cylindrical water dropper, and the cover of elastic sleeve 3 is in on the cylindrical water dropper 2 and cover apopore 22.

Specifically, in the actual irrigation process, the water in the water supply pipe 1 utilizes the water pressure to jack up the elastic sleeve 3 that the cover set up on the cylindrical water dropper 2 so that the elastic sleeve 3 deforms and then forms a gap between the elastic sleeve 3 and the tank bottom of the cylindrical water dropper 2. In this way, the water output from the water outlet hole 22 can flow out through the gap between the elastic sleeve 3 and the cylindrical water dropper 2, and finally the water flows out of the water supply pipe 1 through the water outlet 11 to realize drip irrigation. And in the water supply process, because the two ports of the cylindrical dripper 2 are respectively provided with the first inner chamfers 24, the water resistance can be effectively reduced through the first inner chamfers 24, so that the smooth flowing degree of water flow in the water supply pipe 1 is improved.

And when the water supply is stopped or the water pressure is low, the elastic sleeve 3 tightly wraps the outside of the cylindrical dripper 2 again under the action of the elasticity of the elastic sleeve 3, and then the water outlet 22 is shielded. Therefore, mud blockage caused by that silt is sucked into the water outlet hole of the common drip irrigation head due to negative pressure caused by water cut-off can be avoided, and root blockage caused by that the roots of plants grow into the water outlet hole can also be avoided. And, under the elastic action of elastic sleeve 3, can also increase the water supply pressure through the short time, let the clearance between elastic sleeve 3 and cylindrical water dropper 2 obviously increase, rivers increase in the short time simultaneously, can wash off some plugs, more can avoid dirty stifled than the turbulent flow passageway of general drip irrigation head, have better anti-blocking ability. Because the aperture of the water outlet hole 22 is smaller and is very easy to be blocked, the elastic sleeve 3 is used for protecting, and the anti-blocking performance can be effectively improved. For the water outlet 11, the water outlet 11 cannot be completely blocked by soil due to the large aperture of the water outlet 11. Specifically, when water supply is stopped, the water outlet 11 of the underground water supply pipe 1 can be blocked by soil, and when water supply is carried out, the soil at the water outlet 11 can be flushed away under the action of water pressure, so that normal drip irrigation is realized. The water outlet 11 of the water supply pipe 1 laid on the ground is less likely to be blocked by soil.

Preferably, the cylindrical dripper 2 is provided with an annular groove 21, and the annular groove 21 is internally provided with a plurality of water outlet holes 22 penetrating through the cylindrical dripper 2; the elastic sleeve 3 is sleeved on the cylindrical dripper 2 and is positioned in the annular groove 21, the elastic sleeve 3 covers the water outlet hole 22, and the water outlet 11 is positioned outside the annular groove 21. Specifically, elastic sleeve 3 is arranged in annular groove 21 in order to carry out spacing in the position to elastic sleeve 3, supply pipe 1 sets up a plurality of delivery ports 11 on the outer periphery of every cylinder dripper 2 circles, through arranging a plurality of delivery ports 11, can go out water on the circumferencial direction on the one hand, on the other hand, communicate each other in supply pipe 1 inside between a plurality of delivery ports 11, when going out water, to the silt that covers in delivery port 11 department, because delivery port 11's size is great, the silt of delivery port 11 department can follow the discharge that water is smooth and easy. Also, in order to make the water discharge from the circumference uniform, a plurality of water outlet holes 22 may be provided in the annular groove 21.

Further, in order to more effectively improve the anti-blocking performance, two side walls of the annular groove 21 are respectively provided with a clamping groove 212; the elastic sleeve 3 is sleeved on the cylindrical dripper 2 and is positioned in the annular groove 21, the elastic sleeve 3 covers the water outlet hole 22, and the edge of the elastic sleeve 3 is positioned in the clamping groove 212 on the corresponding side. Since the water pressure inside the water supply pipe 1 varies with the increase of the water supply line, the water pressure is large especially for the area of the water supply pipe 1 having a large pressure near the water supply facility or the like. Under the condition of higher water pressure, the outward deformation degree of the elastic sleeve 3 is increased, and the water yield of the corresponding water outlet part is not increased all the time in the process of increasing the deformation amount of the elastic sleeve 3. Specifically, the water pressure in the water supply pipe 1 pushes the elastic sleeve 3 outwards, and the water in the water supply pipe 1 flows out along the gap between the elastic sleeve 3 and the clamping groove 212; after the water pressure is increased continuously, the distance between the outer surface of the elastic sleeve 3 and the outer side edge of the clamping groove 212 is gradually reduced, so that the water yield of the area with high water pressure can be automatically adjusted, the water yields of different areas of the water supply pipe 1 can be balanced, and the drip irrigation effect and the use reliability can be improved.

Preferably, for a better function of pressure compensation, the edge of the elastic sleeve 3 is provided with pressure compensation notches 31. Specifically, in the region where the pressure in the water supply pipe 1 is high, the outer surface of the elastic sleeve 3 in the region abuts against the surface of the clamping groove 212, so that water does not flow out due to the high pressure. For this reason, by providing the pressure compensation notch 31 at the edge of the elastic sleeve, an independent flow channel is formed between the pressure compensation notch 31 and the surface of the clamping groove 212, so that the water in the water supply pipe 1 can still flow out through the pressure compensation notch 31 under the condition of excessive water pressure.

Wherein, the outer surface of the elastic sleeve 3 is provided with a first diversion trench 32 connected with the pressure compensation notch 31. In particular, the first guide grooves 32 extend on the outer surface of the elastic sleeve 3, and further guide the water flowing out of the pressure compensation gap 31, so as to ensure the normal delivery of the water flow in the case of high water pressure. Meanwhile, the elastic sleeve 3 can deform per se; under the high water pressure condition, along with hydraulic continuation increase, first guiding gutter 32 also takes place deformation, and the cross section of first guiding gutter 32 will diminish thereupon, and then can play regulation flow compensation pressure again. For the first diversion trench 32, the free end portion thereof is exposed outside the slot 212, thereby ensuring that water can reliably and smoothly flow out of the slot 212.

In addition, the inner surface of the elastic sleeve 3 is provided with a second guide groove 33 connected with the pressure compensation notch 31. In particular, for the second guide groove 33, under high pressure conditions, the water flow can be guided to flow into the pressure compensation gap 31 via the second guide groove 33. Meanwhile, under the condition that the water pressure is lower, the flow of water flow can be increased by matching the second diversion trench 33 and the pressure compensation notch 31, so that the water distribution uniformity is more effectively improved, and a more comprehensive pressure compensation effect is obtained.

Of course, in the most preferred embodiment, the pressure compensation notch 31, the first guide groove 32 and the second guide groove 33 are disposed on the elastic sleeve 3 at the same time.

In terms of material selection, the elastic sleeve 3 can be made of elastic materials such as silica gel or rubber under the condition of meeting the elastic requirement of the elastic sleeve 3, and the materials can also meet the requirement of long service life under the conditions of being buried underground for a long time and being soaked by water. The cylindrical dripper 2 can be made of plastic material and processed by injection molding. The material of the water supply pipe 1 may be PP or PE.

Further, the surface of the cylindrical dripper 2 is formed with a concave structure or a convex structure, for example, a pattern structure 23 or a circular groove may be formed. Taking the case of forming a recessed pattern structure 23 on the circumferential surface of the cylindrical dripper 2, the pattern structure 23 is located on one side or both sides of the annular groove 21. Specifically, by forming the pattern structure on the surface of the cylindrical dripper 2, the pattern structure 23 can be connected with the inner wall of the water supply pipe 1 more closely during the extrusion process of the water supply pipe 1, so as to improve the assembling reliability of the cylindrical dripper 2.

Based on the above technical solution, optionally, in order to effectively reduce the manufacturing cost and the manufacturing difficulty of the water reservoir 200, the water reservoir 200 includes an evaporation prevention cover 201, a first impermeable layer 202, and a plurality of first reinforcing plates 203; the first reinforcing plate 203 is used for obliquely arranging the peripheral wall of a pit dug in the desert to form the side wall of the water reservoir 200, the first impermeable layer 202 is used for arranging the peripheral wall and the bottom of the pit, and the evaporation prevention cover 201 covers the upper port of the water reservoir 200.

Specifically, in order to effectively reduce the manufacturing cost and the construction difficulty, the reservoir 200 is constructed in a desert or other areas with severe environments, and in the actual construction process, a pit is first dug in the desert, then the first reinforcing plate 203 is attached to the peripheral wall of the pit to prevent the sand layer from collapsing, and then the first impermeable layer 202 is laid in the pit to form the water storage main body portion of the reservoir 200. Meanwhile, because the evaporation capacity of water is extremely large in the desert environment, in order to reduce the rapid evaporation of water in the water storage tank 200 due to high-temperature drought, an evaporation prevention cover 201 is built at the top of the pit, and under the action of the evaporation prevention cover 201, the water storage tank 200 forms a relatively closed structure so as to effectively slow down the evaporation of water.

The anti-evaporation cover 201 comprises a support 2011 and an anti-evaporation layer 2012, the support 2011 is arranged at the upper part of the pit, and the anti-evaporation layer 2012 covers the support 2011 and is used for shielding the pit. Specifically, during construction, the support 2011 is built around the pit, and then the evaporation-preventing layer 2012 is covered on the support 2011. The support frame 2011 has an arch structure to improve the strength of the overall structure.

In addition, a plurality of second reinforcing plates 204 may be disposed at the periphery of the pit, for being disposed on the ground surface and surrounding the periphery of the pit. Specifically, the plurality of second reinforcing plates 204 are arranged on the periphery of the pit, so that the whole water storage tank 200 has better structural strength and the service durability is improved. And for concrete entities of the first and second reinforcing plates 203 and 204, a prefabricated plate manner may be adopted. Wherein, for the first reinforcing plate 203, the pit is shaped like a funnel, and the first reinforcing plate 203 is a trapezoidal plate or a fan-shaped plate, so that the side wall of the pit can be better supported, and the edges of two adjacent first reinforcing plates 203 are connected together, for example: the gap may be filled by cement.

And, for the first waterproof layer 202, it may be a waterproof coating layer coated on the surface of the first reinforcing plate 203 and the bottom of the recess, or the first waterproof layer 202 may be a waterproof film coated on the surface of the first reinforcing plate 203 and the bottom of the recess.

Meanwhile, greening is realized for better planting in desert areas. The desert greening treatment system further comprises a plurality of planting areas 500, each planting area 500 comprises a planting groove 501 and a second anti-seepage layer 502, the second anti-seepage layers 502 are arranged in the planting grooves 501, planting soil layers 503 are filled in the planting grooves 501, and the drip irrigation pipes 400 are buried in the planting soil layers 503.

Specifically, in the actual planting process, taking a desert as an example, an operator digs the planting groove 501 in the desert, then lays the second impermeable layer 502 in the planting groove 501, fills the planting groove 501 with planting soil that is beneficial for plant growth, and buries the drip irrigation pipe 400 in the planting soil layer 503 during the process of filling the planting soil. Because the second impermeable layer 502 is paved in the planting groove 501, the water can be effectively kept in the planting soil layer 503, and the water loss is reduced, so as to meet the water supply requirement of the planted plants in the drought environment. In addition, the planting grooves 501 are filled with planting soil to meet the growth requirements of plants, and further, conventional plants (such as grapes and the like) can be planted in desert or saline-alkali soil and other areas, so that the problem that the varieties of the plants in the desert and other areas are single is solved, the desert quick greening is more favorably realized, the sediment loss is reduced, and the additional economic added value of crops is generated.

Further, in order to ensure good growth of the plants, in the process of adding the planting soil into the planting groove 501, a base fertilizer layer 504 may be embedded into the planting soil layer 503, the planting soil layer 503 is distributed on both the bottom and the upper part of the base fertilizer layer 504, and the base fertilizer layer 504 is located below the drip irrigation pipe 400. Specifically, the base fertilizer layer 504 is made of materials such as organic fertilizers and the like which help plants to grow, and nutrients can be effectively provided for the plants through the base fertilizer layer 504, so that the plants can grow well.

Based on the desert greening treatment system, the invention also provides a desert greening treatment method, which comprises the following steps: the water in the river flows into the sedimentation tank for sedimentation treatment, the water in the upper layer of the sedimentation tank 100 flows into the water storage tank for storage, the water in the water storage tank 200 is conveyed into the drip irrigation pipe, and the drip irrigation pipe 400 directly supplies water to the root system of the plant.

Specifically, when greening is performed on a desert area, desert greening treatment systems need to be built on two sides of a river in the desert area, and before the river is not dried and cut off, the desert greening treatment systems store irrigation water in advance and supply water to plants in a drought season by using the stored water.

The description is given below by taking the dry desert of Xinjiang tacrolimus.

The dry desert of tachama has the characteristics of small rainfall, more wind and sand activities, large day and night temperature difference and the like, and meanwhile, in the process of changing from winter to summer, snow on the Kunlun mountains is melted to form a river which continuously flows with water for a period of time; when the accumulated snow does not melt any more, the river is dried and flows off due to the influence of local environmental factors. A large amount of stored water is stored in a time period when a river flows by using the desert greening treatment system, and then the stored water is used for continuously irrigating plants after the river is dried.

The specific desert greening planting method comprises the following steps: soil in the planting area is changed to form a planting layer, a drip irrigation pipe is arranged in the planting layer, a planting pit is formed on the planting layer in an excavating mode, and the root of the plant is buried in the planting pit.

Because the desert geological conditions cannot meet the growth requirements of conventional plants, soil replacement treatment is required before planting. Specifically, a planting groove 501 is formed in a planting area by digging, then, second impermeable water layers 502 are arranged at two side parts and the bottom of the planting groove 501, planting soil is put into the planting groove 501, and a drip irrigation pipe is buried in the planting layer formed by the planting soil in the process of putting the planting soil. The planting groove 501 is formed by digging in the desert and the planting soil is filled to meet the growth requirement of conventional plants, thereby solving the problems of single variety of the plants and slow greening effect and efficiency in the desert area. With the increase of time, the planting grooves 501 can be gradually expanded outwards on the two banks of the river to gradually achieve the effect of greening the desert.

Preferably, for the formation of the planting soil layer 503, a first layer of planting soil is laid at the bottom of the planting groove 501, then a layer of fertilizer is laid on the planting soil to form a bottom fertilizer layer 504, a second layer of planting soil is laid into the planting groove again, and the drip irrigation pipe 400 is laid during the laying of the second layer of planting soil. Specifically, planting soil is filled twice to form a base fertilizer layer 504 in the planting soil layer 503, and the base fertilizer layer 504 can provide nutrients for plants more effectively, so that the plants can still grow well in a severe environment.

Further, in the process of digging the planting groove 501, soil dug out by the digging planting groove can be stacked on two sides of the planting groove to form two ridges 505 on the two sides of the planting groove. Specifically, the silt dug out in the desert is distributed on both sides of the planting groove 501 to form two ridges, so that the digging depth of the planting groove 501 can be reduced to reduce the labor intensity of field workers.

Furthermore, as the service life of the desert greening treatment system is prolonged, silt at the bottom of the sedimentation tank 100 can be used for planting soil required by the newly built planting area 500. Specifically, water in the river flows into a sedimentation tank to precipitate silt, upper-layer water in the sedimentation tank flows into a reservoir to be stored, and the water in the reservoir is conveyed to a drip irrigation pipe to supply water to the root system of the plant; when the sedimentation tank is cleaned, the sediment at the bottom is thrown into the planting tank as planting soil. Because the water flowing in the snow melting river flow contains a large amount of mud on the mountains, the mud is accumulated at the bottom of the sedimentation tank 100 for a long time to form sludge rich in nutrients, and after the sludge is obtained by cleaning the sedimentation tank 100 and dried, planting soil can be obtained on site, so that the greening area and range can be gradually expanded along the two sides of the river.
