[0019] The irrigation device is further described below by means of specific embodiments with reference to the accompanying drawings, but the irrigation device is not limited thereto, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the irrigation device shall be included in the protection scope of the irrigation device.

[0020] EMBODIMENT

[0021] The irrigation device for farmland water conservancy projects described in the embodiment has the advantages that Figure 1 , Figure 2 and Figure 4As shown, the irrigation device body 1 is a conventional drip irrigation system, which mainly consists of a water pump, a filter, a pipeline (a main pipe, a branch pipe, a drip irrigation pipe), a dripper or a drip irrigation tape, a control valve and the like;

[0022] The irrigation device body 1 is independently provided with a plug-in pipe 5 communicating with the water outlet hole of the drip irrigation pipe, and a small gap exists between the plug-in pipe 5 and the water outlet hole, so that the plug-in pipe 5 can be inserted into and removed from the water outlet hole. After the plug-in pipe 5 is inserted into the water outlet hole, the water in the drip irrigation pipe can be transported into the plug-in pipe 5;

[0023] Further, as shown in Figure 1 and Figure 2 In the embodiment, two elastic clamps 2 are preferably provided, which are made of corrosion-resistant materials such as stainless steel, polyethylene and polyvinyl chloride, and have a certain elasticity. The plug-in pipe 5 is sleeved with a positioning sleeve 11 at one end outside the water outlet hole, and is sleeved with a sealing ring 4, which is located between the positioning sleeve 11 and the drip irrigation pipe. After the plug-in pipe 5 is inserted into the water outlet hole, the sealing ring 4 can seal the gap between the water outlet hole and the plug-in pipe 5, so as to prevent water leakage and waste of water resources. The two elastic clamps 2 are fixed on the positioning sleeve 11 in a mirror-symmetrical manner, and are clamped on the drip irrigation pipe, as shown in Figure 1 and Figure 4As shown, the two elastic clamps 2 are combined in a C-shaped structure. After the elastic clamps 2 are clamped on the pipe, they push the positioning sleeve 11 to move towards the pipe by their elasticity, thereby extruding the sealing ring 4 to make the sealing ring 4 deform to seal the gap. The elastic clamps 2 fix the insertion pipe 5 to prevent the insertion pipe 5 from coming out. Two blocking plates 3 are symmetrically fixed horizontally on the end of the insertion pipe 5 towards the inside of the pipe. The end of the blocking plate 3 is provided with a protrusion for preventing the insertion pipe 5 from coming out of the water outlet hole. The protrusion on the blocking plate 3 is in a semicircular structure. When the insertion pipe 5 is inserted into the water outlet hole of the pipe, the blocking plate 3 is extruded and bent. After the protrusion on the blocking plate 3 completely enters the pipe, the pipe wall blocks the protrusion, thereby preventing the insertion pipe 5 from easily coming out of the water outlet hole. The semicircular protrusion on the blocking plate 3 is convenient for guiding the bending of the blocking plate 3, thereby facilitating the insertion pipe 5 to enter and exit the water outlet hole. Of course, the protrusion on the blocking plate 3 can also be in a triangular structure. In use, the insertion pipe 5 is inserted into the water outlet hole, so that the blocking plate 3 is extruded and bent. After the protrusion on the blocking plate 3 completely enters the pipe, the pipe wall blocks the protrusion to prevent the insertion pipe 5 from easily coming out. At the same time, the two elastic clamps 2 are clamped on the pipe, thereby fixing the insertion pipe 5 by the protrusion on the blocking plate 3 and the two elastic clamps 2 to prevent the insertion pipe 5 from coming out of the water outlet hole. The whole scheme constitutes a fixing assembly for fixing the insertion pipe 5 on the pipe. Of course, the fixing assembly can also use a clamp. The clamp is a fixing member formed in a ring shape by two steel wires. One steel wire structure is fixed on the insertion pipe 5. When the insertion pipe 5 is inserted into the water outlet hole, the clamp is clamped on the pipe and connected by a screw, thereby effectively fixing the insertion pipe 5 on the pipe.

[0024] The end of the insertion pipe 5 towards the outside of the water outlet hole is connected with a soft pipe 6 communicating therewith. The other end of the soft pipe 6 is connected with a ground pipe 8 communicating therewith, as shown in Figure 1 The two ends of the soft pipe 6 are sleeved on the insertion pipe 5 and the ground pipe 8 respectively, and are fastened and connected by interference fit, thereby facilitating disassembly and replacement. During irrigation, the water in the pipe on the irrigation device body 1 can pass through the insertion pipe 5 and the soft pipe 6 in turn and be transmitted to the ground pipe 8.

[0025] The ground pipe 8 is provided with a plurality of water dripping holes 10. In use, the ground pipe 8 can be inserted into the soil at the root of the plant, so that the water in the ground pipe 8 can be directly injected into the soil at the root of the plant through the water dripping holes 10 on the ground pipe 8 when irrigation is needed, thereby reducing the waste caused by evaporation of water, improving the utilization rate of water, and achieving the effect of water saving.

[0026] The end of the ground pipe 8 is in a tapered structure, as shown in Figure 1 and Figure 3As shown, the tapered end of the insertion tube 5 can facilitate its insertion into the ground, and the tapered end will transmit the force more concentratedly to the contact point with the soil, and such concentrated force will help to cut or push away the soil particles;

[0027] A soil baffle 9 is fixed on the outer wall of the ground pipe 8 in a slanting manner corresponding to each drip hole 10 to prevent the soil from blocking the drip hole 10; in the embodiment, the drip holes 10 are arranged at equal intervals along the length direction of the ground pipe 8, and the drip holes 10 are directed towards the plant during use, so that directional irrigation is performed, water irrigation in useless directions is avoided, the utilization rate of water resources is improved, and water resources are saved; the number of the soil baffles 9 is the same as that of the drip holes 10, and the soil baffles 9 are fixed on the pipe wall of the ground pipe 8 below the drip holes 10, as shown in Figure 1 As shown, the soil baffle 9 is in a left-high right-low slanting manner, and the right-low end is fixed on the pipe wall of the ground pipe 8 below the drip hole 10; the soil baffle 9 shields the soil on the side of the ground pipe 8 to prevent the drip hole 10 from being blocked by the soil when the ground pipe 8 is inserted into the soil, thereby affecting the water outlet effect;

[0028] A plurality of positioning plates 7 are fixed on the outer wall of the ground pipe 8; in the embodiment, only one positioning plate 7 is used, and more positioning plates 7 can also be used according to the actual situation, as shown in Figure 1 As shown, the positioning plate 7 is fixed on the pipe wall along the length direction of the ground pipe 8; when the ground pipe 8 is inserted into the soil, the positioning plate 7 will also be inserted into the soil; when the weather with large temperature difference is encountered, the capillary tube will expand and contract due to heat, so that one end of the hose 6 will swing with the change of the position of the water outlet hole; the hose 6 will exert a pulling force and a torsional force on the ground pipe 8 during the swinging process, and the positioning plate 7 will position the ground pipe 8 through the contact area with the soil to prevent the ground pipe 8 from rotating or tilting to the side, keep the drip hole 10 directed towards the root of the plant, and prevent the irrigation direction of the drip hole 10 from deviating;

[0029] A chamfer is formed on the side wall of the positioning plate 7 towards the ground, so that the bottom of the positioning plate 7 is in a blade shape, thereby facilitating the insertion of the positioning plate 7 into the soil.

[0030] In actual use, the insertion tube 5 is inserted into the water outlet hole of the capillary pipe, so that the blocking plate 3 is pressed and bent, and after the protrusions on the blocking plate 3 completely enter the capillary pipe, the pipe wall of the capillary pipe will block the protrusions, preventing the insertion tube 5 from easily falling out, and at the same time, the two elastic clamps 2 will be clamped on the capillary pipe, thereby fixing the insertion tube 5 through the protrusions on the blocking plate 3 and the two elastic clamps 2, preventing the insertion tube 5 from falling out of the water outlet hole; then the ground pipe 8 is inserted into the soil, and the water dripping hole 10 faces the direction of the plant, thereby directional irrigation is carried out, avoiding irrigation in useless directions, improving the utilization rate of water resources, and saving water resources; when encountering weather with large temperature difference, the capillary pipe will expand and contract with heat, causing misalignment between the water outlet hole and the plant, but one end of the hose 6 can swing a distance with the water outlet hole due to its soft characteristics, and the water flow in the capillary pipe can still be transported to the ground pipe 8 through the insertion tube 5 and the hose 6, and the water in the ground pipe 8 can be directly injected into the soil at the root of the plant through the water dripping hole 10 thereon, without worrying about the thermal expansion and contraction of the capillary pipe affecting the irrigation effect.
