[0002] The average annual precipitation in my country's extremely arid areas is less than 50 mm. Water resources have become a decisive factor restricting the normal growth of vegetation in extremely arid areas. Developing an efficient, convenient, simple and low-cost water replenishment device is a key measure to solve the water shortage of vegetation in extremely arid areas. When carrying out grassland ecological restoration work in extremely arid areas, artificial grassland construction projects are generally used as the main measure.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] As attached Figure 1 To the attached Figure 8 As shown:

[0034] Example 1:

[0035] The present invention provides a drip irrigation device for replenishing water for vegetation in extremely arid areas, comprising a water supply barrel 1;

[0036] A faucet 2 is installed on the lower side of the outer wall of the water supply barrel 1, and a water divider 3 is installed on the lower side of the outer surface of the faucet 2. The function of the water divider 3 is to divert the water flowing out of the water supply barrel 1 into multiple paths to meet the water replenishment needs of vegetation in different areas. Three infusion tubes 4 are installed at the bottom end of the water divider 3. The infusion tubes 4 can be made of soft and durable rubber tubes or plastic tubes. A short drip irrigation mechanism 5 or a long drip irrigation mechanism 6 is installed at the other end of the three infusion tubes 4. The components of the short drip irrigation mechanism 5 and the long drip irrigation mechanism 6 are the same, but the length of the short drip irrigation mechanism 5 is set to a 20cm version, and the length of the long drip irrigation mechanism 6 is set to a 40cm version. A fixing bracket 7 is installed at the bottom end of the water supply barrel 1. The function of the fixing bracket 7 is to fix the water supply barrel 1 at a suitable height and position to ensure the stability of the equipment during use;

[0037] The short drip irrigation mechanism 5 includes a drip irrigation dripper 51, a drip observation tube 52, a flow adjustment knob 53, a nylon mesh 54, a rubber ring 55, a depth scale 56 and a tapered bevel head 57. The drip observation tube 52 is installed on the upper part of one end of the drip irrigation dripper 51, and the other end of the drip observation tube 52 is connected and communicated with the other end of the infusion tube 4. The flow adjustment knob 53 is set in the middle of the outer wall of the drip observation tube 52. The flow adjustment knob 53 can change the size of the channel inside the drip observation tube 52, thereby adjusting the flow of water to meet the water supply needs of different vegetation. The nylon mesh 54 is installed at the top of the drip irrigation dripper 51, and the rubber ring 55 is installed at the connection between the drip irrigation dripper 51 and the nylon mesh 54. The rubber ring 55 ensures good sealing of the connection. The depth scale 56 is set in the middle of the outer wall of the drip irrigation dripper 51. The depth scale 56 can help the operator accurately grasp the depth of the drip irrigation dripper 51 inserted into the soil to ensure the drip irrigation effect. The conical bevel head 57 is installed at the bottom of the drip irrigation dripper 51. The design of the conical bevel head 57 facilitates the insertion of the drip irrigation dripper 51 into the soil and reduces the resistance during insertion.

[0038] The drip irrigation dripper 51 is made of a transparent plastic material, which is convenient for observing and estimating the liquid flow rate of the drip observation tube 52 inside it. The drip irrigation dripper 51 also has certain strength and corrosion resistance. A 15mm diameter opening is opened in the middle of the top of the drip irrigation dripper 51. The opening facilitates the use of atmospheric pressure to smoothly input the liquid in the drip irrigation dripper 51 into a certain depth of soil layer. The drip observation tube 52 is located at one end inside the drip irrigation dripper 51 with an oblique cut design to make the water drip out more evenly and facilitate the counting of liquid drops. The nylon mesh 54 has a pore size of 1mm to prevent windblown sand or other impurities from falling into the drip irrigation dripper 51.

[0039] Working principle: First, the outflow of water in the water supply barrel 1 can be controlled by the faucet 2, and then the water is divided into three infusion pipes 4 through the water distributor 3. If short-distance drip irrigation is performed, the water flows into the short drip irrigation mechanism 5 through the infusion pipe 4. In the short drip irrigation mechanism 5, the water enters the drip irrigation dripper 51 through the drip observation tube 52, and then enters the soil of the plant root system through the conical bevel head 57. The opening at the top of the drip irrigation dripper 51 can use atmospheric pressure to push the liquid in the drip irrigation dripper 51 into the soil. The water can be smoothly input into the soil layer at a certain depth, and can directly penetrate into the root depth of plants in arid areas for precise depth control, thereby realizing water-saving drip irrigation. Since one end of the drip observation tube 52 is designed with an oblique cut, the water flow can be dripped into the drip irrigation dripper 51 more evenly. Since the drip irrigation dripper 51 is transparent, the dripping situation of the drip observation tube 52 can be observed. By rotating the flow adjustment knob 53, the water flow entering the drip irrigation dripper 51 can be accurately adjusted, thereby controlling the amount of water replenishment. In the process of drip irrigation, the nylon mesh 54 can prevent wind and sand or other impurities from falling into the drip irrigation dripper 51 and clogging the drip irrigation dripper 51. At the same time, the rubber ring 55 can seal the connection between the drip irrigation dripper 51 and the nylon mesh 54 to ensure the stability and reliability of the drip irrigation. If deep soil drip irrigation is carried out, the short drip irrigation mechanism 5 is replaced with the long drip irrigation mechanism 6. Its working principle is similar to that of the short drip irrigation mechanism 5, except that it can meet the drip irrigation needs of deeper soil. Therefore, according to the root growth characteristics of different vegetation, the short drip irrigation mechanism 5 or the long drip irrigation mechanism 6 that is easy to replace can be selectively used. The water replenishment depth and water replenishment amount can be accurately controlled, and the drought stress of vegetation can be alleviated efficiently and quickly, helping vegetation in arid areas to survive the drought period, increasing the biomass and vegetation coverage of vegetation in arid areas, and improving the growth and survival rate of vegetation, thereby enhancing the wind and sand fixation ability of vegetation and improving the restoration effect and efficiency of vegetation. Compared with surface drip irrigation water replenishment measures, it significantly reduces the water consumption of vegetation in desert areas and reduces the water cost of artificial restoration and management of vegetation in desert areas.

[0040] Example 2:

[0041] This embodiment is basically the same as the previous embodiment, except that the fixed bracket 7 includes a folding base frame 71, a supporting square steel 72, a drill hole 73 and a latch 74. There are four supporting square steels 72 and four latches 74. The four supporting square steels 72 are movably plugged into the four corners of the top of the folding base frame 71. The supporting square steels 72 can be hollow square steels to ensure strength while reducing weight, making it easy to carry and install. There are multiple drill holes 73, which are respectively opened in the middle of the outer walls of both sides of the four supporting square steels 72. The four latches 74 are respectively plugged into the corresponding drill holes 73 on the outer walls of both sides of the four supporting square steels 72.

[0042] The folding chassis 71 includes a first steel plate 711, a bolt 712, a second steel plate 713, a collar 714 and a nut 715. The bolt 712 is threadedly installed in the middle of the top of the first steel plate 711. The bolt 712 is made of high-strength, wear-resistant material to ensure the stability of the connection. The second steel plate 713 is inserted and installed in the middle of the outer surface of the bolt 712. The second steel plate 713 and the first steel plate 711 are both made of high-strength, corrosion-resistant alloy steel plates to ensure that they can withstand the weight of the water supply barrel 1 and the water inside. There are four collars 714, and the four collars 714 are respectively installed at both ends of the first steel plate 711 and the second steel plate 713. The collar 714 can be made of metal and welded to the steel plate. The four collars 714 are respectively sleeved and installed on the outer surfaces of the four supporting square steels 72. The nut 715 is threadedly installed on the outer surface of the bolt 712.

[0043] A receiving groove is provided in the middle of the top of the first steel plate 711, which can accommodate the head of the bolt 712 to ensure the flatness of the top surface of the first steel plate 711. The middle of the outer surface of the second steel plate 713 is set to a concave structure, which is conducive to the expansion and contraction between the second steel plate 713 and the first steel plate 711, and the top surface of the second steel plate 713 is flush with the top surface of the first steel plate 711, so that the first steel plate 711 and the second steel plate 713 support the water supply barrel 1 together. The bottom end surface of the supporting square steel 72 is set to a bevel. The design of the bevel facilitates the insertion of the supporting square steel 72 into the soil, reduces the resistance during insertion, improves the stability of the equipment, and facilitates the fixing of the supporting square steel 72 in the desert Gobi environment.

[0044] Working principle: first unfold the folding chassis 71, and preliminarily combine the first steel plate 711 and the second steel plate 713 by inserting the bolts 712. Use the nut 715 to tighten the outer surface of the bolt 712 to fix the relative positions of the first steel plate 711 and the second steel plate 713. At this time, the concave structure in the middle of the outer surface of the second steel plate 713 cooperates with the first steel plate 711, and the top surfaces of the two are flush, which is conducive to the subsequent placement of the water supply barrel 1. Since the bottom end surface of the supporting square steel 72 is set as a bevel, it can contact the ground more stably. Then, according to the actual terrain and the placement requirements of the water supply barrel 1, select the drill hole 73 of the appropriate height from the multiple drill holes 73 in the middle of the outer wall of both sides of the supporting square steel 72, and insert the four pins 74 into the corresponding ones on the outer walls of both sides of the four supporting square steels 72. Drill holes 73 to fix the height and position of the folding base frame 71. Afterwards, the four rings 714 are respectively sleeved on the outer surface of the supporting square steel 72 to fix the folding base frame 71 on the supporting square steel 72. Finally, the water supply barrel 1 is placed on the fixed bracket 7 constructed by the folding base frame 71 and the supporting square steel 72. This can achieve rapid installation of drip irrigation equipment in extremely arid areas. The installation and erection of the water supply barrel 1 is simple and not restricted by the terrain, which improves the equipment deployment efficiency, reduces the installation cost and time cost, and is suitable for vegetation water replenishment operations in various complex terrain environments. It is also convenient for subsequent drip irrigation operations. The fixed bracket 7 has the characteristics of quick installation, simple structure, low cost and easy use. It is not restricted by the terrain and can be quickly installed to provide stable support for the drip irrigation equipment.

[0045] Example 3:

[0046] This embodiment is substantially the same as the previous embodiment, except that three water diversion switches 31 are provided on the lower side of the outer wall of the lower water distributor 3. By rotating the water diversion switches 31, the water flow rate of each drip irrigation branch can be precisely controlled. In extremely arid areas, the water requirements of different vegetation may vary. The water diversion switches 31 can flexibly adjust the water flow of each branch according to actual needs, thereby achieving precise drip irrigation and avoiding waste of water resources. A connecting rope 8 is installed at one end of the water distributor 3, and a depth-setting auxiliary device 9 is installed at the other end of the connecting rope 8. A depth-setting auxiliary guide pipe 10 is sleeved and installed on the lower portion of the outer surface of the outermost short drip irrigation mechanism 5.

[0047] Handles 11 are installed on both sides of the outer wall of the water supply barrel 1. The handles 11 facilitate carrying the water supply barrel 1 in complex terrain in extremely arid areas. A barrel cover 12 is threadedly installed on the upper part of the outer surface of the water supply barrel 1. A heat-insulating film 13 is installed in the middle of the outer surface of the water supply barrel 1. The heat-insulating film 13 prevents the water supply barrel 1 from forming a convex lens effect in the outdoor lighting environment after being filled with water, which may cause a fire risk in the wild.

[0048] The depth-setting aid 9 is made of threaded steel with a diameter of 20 mm, and a conical head is provided on the lower side of the outer surface of the depth-setting aid 9, which facilitates the quick spiral insertion of the depth-setting aid 9 into the soil to complete the drilling operation. The outer surfaces of the depth-setting aid 9 and the depth-setting aid guide tube 10 are both provided with multiple scale lines, which can intuitively display the depth of insertion into the soil, making it convenient for operators to accurately adjust the drip irrigation depth according to the root depth of different vegetation, thereby achieving precise drip irrigation and further improving the utilization efficiency of water resources.

[0049] A conical cover is installed at the bottom end of the fixed-depth auxiliary guide pipe 10. The conical cover facilitates the rapid insertion of the fixed-depth auxiliary guide pipe 10 into the soil, and a plurality of diversion holes with a diameter of 5 mm are opened on the outer surface of the conical cover. The diversion holes facilitate the input of water in the fixed-depth auxiliary guide pipe 10 into the root soil of the plant. The fixed-depth auxiliary guide pipe 10 is set as a hollow metal pipe, and the inner diameter of the fixed-depth auxiliary guide pipe 10 is consistent with the outer diameter of the drip irrigation dripper 51, which facilitates the insertion of the drip irrigation dripper 51 into the fixed-depth auxiliary guide pipe 10;

[0050] The water supply barrel 1 is made of dark, opaque plastic material, which can prevent direct sunlight from entering the barrel, reduce the impact of photosynthesis on water quality, and also reduce the rate of water evaporation due to light. Its material can be corrosion-resistant and aging-resistant plastic to extend its service life. The capacity of the water supply barrel 1 is 20 to 40L. This capacity design takes into account the limited water resources in extremely arid areas and can meet the water replenishment needs of vegetation within a certain period of time. It is easy to carry and transport. The heat-insulating film 13 is set to an outer aluminum film and an inner heat-insulating cotton. The aluminum film can prevent the water temperature in the water supply barrel 1 from rising too high due to direct sunlight. The aluminum film has good heat-insulating and heat-insulating properties, which can reduce the influence of the external ambient temperature on the water temperature in the barrel, reduce the water evaporation rate, keep the water temperature relatively stable, and is conducive to the absorption of water by vegetation. The heat-insulating cotton can play an insulating role.

[0051] Working principle: The operator first opens the bucket cover 12 on the water supply bucket 1, injects an appropriate amount of water into the water supply bucket 1, and then lightly covers and does not completely tighten the bucket cover 12, which can prevent water evaporation and impurities from entering and facilitate water to flow out to subsequent mechanisms. Then, the water supply bucket 1 is carried to a suitable position through the handle 11 to drip irrigate plants in arid areas. During drip irrigation, if it is necessary to accurately control the drip irrigation depth, the depth-setting auxiliary component can be used. The operator holds the depth-setting auxiliary device 9 and inserts the depth-setting auxiliary device 9 into the soil near the root of the plant according to the multiple scale lines on the outer surface of the depth-setting auxiliary device 9 to determine the required depth. Then, the depth-setting auxiliary device 9 is pulled out, and the short drip irrigation mechanism 5 or the long drip irrigation mechanism 6 is inserted into the hole drilled for the fixed depth. The depth-setting auxiliary device 9 can accurately measure and control the depth of insertion into the soil, helping the operator to place the drip irrigation dripper 51 It is delivered to the root layer of plants in arid areas at a fixed depth to ensure the accurate water replenishment depth. When using the fixed-depth auxiliary diversion tube 10, the operator inserts the fixed-depth auxiliary diversion tube 10 into the soil through the conical cover. The multiple scale lines on the outer surface of the fixed-depth auxiliary diversion tube 10 can assist in positioning the depth. Then the drip irrigation dripper 51 is placed in the fixed-depth auxiliary diversion tube 10 with a determined depth position, so that water flows evenly through the drip irrigation dripper 51 through the diversion holes on the conical cover of the fixed-depth auxiliary diversion tube 10 around the roots of the plants. This approach can not only assist in depth setting, but also evenly disperse the water flow, further improve the accuracy and effect of drip irrigation, and ensure that the roots of vegetation obtain sufficient and appropriate water, effectively solving the problem of drip irrigation depth control, achieving precise depth and uniform drip irrigation, improving water resource utilization, and helping vegetation in extremely arid areas to grow better.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
