fig. 2 is a sectional structural view of the present invention in embodiment 2.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
Specific example 1:
as shown in fig. 1, the drip irrigation device comprises an inner pipe 1 and an outer pipe 2 which are coaxially arranged, wherein the outer pipe 2 is sleeved outside the inner pipe 1, a plurality of sealing partitions are uniformly arranged between the inner pipe 1 and the outer pipe 2 along the axial direction to form a plurality of repeatedly arranged drip irrigation units, each drip irrigation unit is formed by combining two adjacent sealing partitions and the middle part of each drip irrigation unit, namely the drip irrigation unit comprises a left sealing partition 3, a right sealing partition 7, an inner pipe section 4 and an outer pipe section 5, the left sealing partition 3 and the right sealing partition 7 are adjacent two sealing partitions, the inner pipe section 4 is a part of the inner pipe 1, the outer pipe section 5 is a part of the outer pipe 2, a buffer cavity 6 is arranged between the inner pipe section 4 and the outer pipe section 5, an inner water outlet 9 communicated with the buffer cavity 6 is arranged on the inner pipe section 4, and at least two outlet ports 8 communicated with the buffer cavity 6 are arranged on the outer pipe section 5.
Because the conveying distance is relatively far, the internal pressure is relatively large, and the water pressure resistant grade of the inner pipe section 4 is higher than that of the outer pipe section 5.
In order to ensure that the water flow in the inner pipe section 4 enters the buffer cavity 6 to have larger buffer and difference to generate larger pressure difference, the radius of the section 5 of the outer pipe is larger than that of the inner pipe section 4; on the other hand, the inner diameter of the outer tube 5 gradually increases from the left and right ends toward the middle a direction.
Further, the diameter of the outlet 8 is smaller than the diameter of the inner outlet 9; the inner tube 1, the outer tube 2 and the sealing partition are integrally formed.
When the invention is used, water flow with certain pressure is injected into one end of the inner pipe 1, when the water flow is filled into proper amount, the water flow with certain water pressure is sprayed into the buffer cavity 6 from the inner water outlet 9, and turbulence is formed in the buffer cavity 6 due to the different inner diameters of the outer pipe sections 5 of the buffer cavity 6, so that residual sediment and microorganisms in the buffer cavity 6 are washed out and cleaned, and the residual sediment and microorganisms are washed out of the pipe from the outlet 8; after the sprinkling irrigation is finished, the inner diameter of the outer pipe section 5 is different in size, so that the residual water is discharged in time, and the residues of sediment and the breeding of microorganisms are further avoided.
Through the programming structural design, the water yield and the drip irrigation time of each water outlet 8 can be controlled according to the diameter relation of the inner pipe 1 and the outer pipe 2, the cross-sectional area relation of the water outlet 8 and the inner water outlet 9 and the number of the water outlets 8.
Specific example 2:
the difference from embodiment 1 is that the inner wall of the outer pipe 5 is formed in a different manner, and as shown in fig. 2, the inner diameters of the outer pipe 5 on both sides of each outlet 8 are sequentially increased in the direction of the left and right sides B. In this way, when the water flow is sprayed into the buffer cavity 6 from the inner water outlet 9, turbulence is more easily formed to increase the scouring and cleaning effects, and on the other hand, residual water in the buffer cavity 6 flows out from the outlet 8 more easily after irrigation is finished, so that the cleaning and drying in the buffer cavity 6 are ensured.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be replaced with others, which may not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
