Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the present invention by way of specific embodiments thereof.

Example 1

As shown in fig. 1-3, the present embodiment provides a water-saving composite embedded infiltrating irrigation equipment, which comprises an infiltrating irrigation pipeline 1 and an automatic adjusting component.

As shown in fig. 1, the automatic adjusting assembly is disposed inside the soil and outside the infiltrating irrigation pipe 1. The infiltrating irrigation pipeline 1 comprises a plurality of sections, and the length of the automatic adjusting assembly is less than the length from each section of infiltrating irrigation pipe to 1, and is used for detecting the infiltrating irrigation degree of the infiltrating irrigation pipeline to soil. In the embodiment, a plurality of infiltrating irrigation pipelines 1 can be selected at will, and the automatic adjusting components are arranged on the outer sides of the infiltrating irrigation pipelines.

The automatic regulating assembly comprises a pipeline body 2, a water body channel 3 is arranged in the direction of the length of the pipeline body 2 along the pipeline body 2, and the water body channel 3 divides the pipeline body 2 into a first end 4 and a second end 5 which are integrally formed.

The interior of the pipe body 2 forms a first space 6, and the infiltrating irrigation pipe 1 is arranged in the first space 6. The first end 4 of the pipe body 2 is bent in a direction away from the first space 6 to form a groove body 7. The groove 7 may be of any shape as long as the bending direction thereof is directed away from the first space, i.e., there is no contact between the opening of the groove 7 and the first space 6. Preferably, the groove 7 may have a circular arc shape.

The second end 5 of the pipe body 2 forms a seal 8 which can be engaged with the trough body 7 to close the water passage 3. When the sealing body 8 is tightly contacted with the tank body 7, the water body channel 3 is closed; when the sealing body 8 is separated from the tank body 7, the water body channel 3 is opened.

In order to enable the water body channel 3 to be automatically opened and closed according to the soil environment between the tank body 7 and the sealing body 8, an expansion and contraction member 9 is arranged in the tank body 7.

The expansion and contraction member 9 is preferably made of water-absorbent rubber. Of course, the expansion and contraction member 9 in this embodiment may be other expansion and water absorption materials. Since the curved direction of the tank body 7 in this embodiment is away from the first space 6, the expansion and contraction member 9 provided in the tank body 7 performs moisture exchange only with the soil outside thereof. Before the infiltrating irrigation begins, the humidity in the soil is low, the moisture in the expansion and contraction part 9 is minimum, and the volume is also minimum. Along with the infiltrating irrigation pipeline 1, the infiltrating irrigation water yield is gradually increased, the soil humidity is also gradually increased, and at the moment, the expansion and contraction part 9 continuously absorbs water from the soil to expand; when the volume of the expansion and contraction piece 9 expands to a certain degree, the groove body 7 is expanded and gradually approaches to the sealing body 8 until the expansion and contraction piece pushes the groove body 7 and the sealing body 8 to be in close contact.

In order to further enable the signal of sufficient soil humidity to be obtained by the operator, the present embodiment further provides a first sensing component at one side of the tank body 7 facing the sealing body 8, and a second sensing component at one side of the sealing body 8 facing the tank body 7. Therefore, when the groove body 7 is tightly contacted with the sealing body 8, the first sensing component is also contacted with the second sensing component.

The first sensing component and the second sensing component may be sensors, and are connected to an external device through signals. After first response subassembly and second response subassembly contact, the signal of soil moisture saturation is transmitted to external equipment promptly, then reminds operating personnel to close the water source switch, finishes the filtration irrigation work.

Inside this embodiment set up soil with the automatically regulated subassembly, the setting of expansion contraction subassembly is in the cell body of the outside crooked formation of first end of pipeline body for the expansion contraction spare only can carry out moisture exchange with soil, and the water that can not flow in the direct contact infiltration irrigation pipeline can not be in the inflation state for a long time, and sensitivity is better. Along with the going on of filtration irrigation, the moisture in the soil increases, and soil humidity increases gradually, and the expansion contraction body can absorb moisture from soil for the continuous grow of volume, and then drive the cell body and warp, and gradually with the seal contact, make the water passageway close.

Set up first response subassembly and second response subassembly on cell body and the seal respectively, when first response subassembly and second response subassembly contact, can send off signal, remind filtration irrigation operating personnel soil moisture saturation, and then hold the opportunity and close the water source switch, finish filtration irrigation work.

Consequently, the water-saving compound embedded filtration irrigation equipment of this embodiment can detect soil moisture through first response subassembly and second response subassembly for operating personnel can grasp the end time of filtration irrigation better, optimizes the irrigation effect of filtration irrigation, and practices thrift the water resource.

Preferably, in order to make the structure of the whole infiltrating irrigation equipment more stable, the bottom of the infiltrating irrigation pipeline 1 is provided with a connecting block 10, and the bottom of the pipeline body 2 is provided with a connecting groove. The filtration irrigation pipeline 1 and the automatic adjusting assembly are fixedly connected through a connecting block 10 and a connecting groove. The connecting block can be in a trapezoid shape, a boss shape or any boss shape.

Due to the influence of the gravity, the arrangement of the filtration irrigation holes and the like at a constant speed, the water body seeped out from the filtration irrigation pipeline is distributed more at a deeper position of the soil. Preferably, in order to ensure that the humidity of the soil contacted by the expansion and contraction member 9 has certain representativeness, the height of the groove body 7 in the embodiment at least needs to be higher than the height of the central axis of the infiltrating irrigation pipeline 1, so as to prevent the expansion and contraction member 9 from being too low to cause premature expansion and deformation and contact the first sensing assembly and the second sensing assembly, so that the infiltrating irrigation is ended prematurely, and the irrigation effect is influenced.

As the crop absorbs and utilizes the moisture, the moisture in the soil is gradually reduced, the moisture in the expansion and contraction member 9 is also transferred to the soil, and the expansion and contraction member 9 is reduced in volume. In order to enable the tank body 7 and the sealing body 8 to be smoothly separated after the volume of the expansion and contraction part 9 is reduced, a plurality of elastic resetting parts 11 are further arranged at the opening of the tank body 7, so that the tank body 7 and the sealing body 8 are automatically separated after the soil humidity is reduced, and the water channel 3 is opened.

Specifically, the elastic restoring member 11 is made of an elastic material, such as rubber, silicone, or the like. The elastic reset piece 11 can be block-shaped, slice-shaped or bar-shaped, and two ends of the elastic reset piece are respectively connected with the opening of the groove body 7, namely two ends of the circular arc. When the expansion and contraction piece props the groove body 7, the elastic reset piece is also stretched and deformed; when the expansion and contraction piece is dehydrated, the elastic reset piece recovers deformation to drive the groove body to automatically reset and separate from the sealing body.

Furthermore, in order to avoid the elastic restoring member 11 from affecting the water absorption and dehydration of the expansion and contraction member 9, the elastic restoring member 11 is further provided with a plurality of water permeable holes 111.

The first end 4 of the pipe body 2 is bent in a direction away from the first space 6 to form a groove body 7, and the second end forms a sealing body 8.

The present embodiment differs from embodiment 1 in that an anti-clogging structure 12 is further provided on the outer side of the automatic adjusting assembly. The anti-clogging structure 12 may be a porous and water-permeable material such as sponge, non-woven fabric, etc. In this embodiment, prevent blockking up structure 12 and set up in the outside of whole automatically regulated subassembly for prevent that soil, grit etc. from blockking up water passageway 3, avoid influencing the timely contact between first response subassembly and the second response subassembly.
