Description

Water-saving composite embedded infiltrating irrigation equipment

Technical Field

In order to solve the above problems, an infiltrating irrigation technique is proposed.

The infiltrating irrigation technology lays infiltrating irrigation pipes in the soil of the crop root system active layer in advance, irrigation water sources are directly sent to the crop root system soil through pipelines, water slowly and uniformly enters the plant root zone by virtue of the functions of capillary water absorption and water potential of the soil, the problems of water loss and the like caused by surface water evaporation and injection in the common irrigation technology can be solved, the soil can be loosened, pollution is reduced, crop growth is promoted, and the infiltrating irrigation technology is a novel water-saving irrigation technology with low cost, high income and environmental friendliness and convenience.

In the use process of the infiltrating irrigation equipment, when irrigation is needed, a water source switch is turned on, and water flows permeate out of the pipeline through the infiltrating irrigation pipeline and are absorbed by soil and crops. However, since the entire infiltrating irrigation facility is buried under the ground, it is difficult for an operator who performs irrigation work above the ground to determine the humidity of the soil, and thus it is difficult to grasp the opening and closing time of the water source switch. However, too early closing time of the water source switch can lead to poor infiltrating irrigation effect, too late closing can lead to too much water seepage and cause water source waste.

Therefore, it is necessary to provide a device capable of timely feeding back the infiltration amount of the infiltration irrigation, and timely judging the infiltration irrigation work.

Detailed Description

The present invention will be described in detail below with reference to specific embodiments for better explaining the present invention.

Example 1

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

As shown in fig. 1, the automatic regulating assembly is arranged inside the soil and outside the infiltrating irrigation pipeline 1. The infiltrating irrigation pipeline 1 comprises a plurality of infiltrating irrigation pipelines, and the length of the automatic adjusting component is smaller 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 the soil. In the embodiment, a plurality of infiltrating irrigation pipelines 1 can be selected at will, and an automatic adjusting component is arranged on the outer side of the infiltrating irrigation pipeline 1.

The automatic adjusting component comprises a pipeline body 2, a water body channel 3 is formed 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 first space 6 is formed inside the pipe body 2, and the infiltrating irrigation pipe 1 is arranged inside 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 7. The tank 7 may be of any shape as long as its bending direction is directed away from the first space, i.e. there is no contact between the opening of the tank 7 and the first space 6. Preferably, the groove 7 may be arc-shaped.

The second end 5 of the conduit body 2 forms a seal 8 which is capable of conforming to the channel 7 to close the body of water 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 channel 3 to be automatically opened and closed according to the soil environment between the tank 7 and the sealing body 8, the present embodiment provides an expansion and contraction member 9 in the tank 7.

The expansion and contraction member 9 is preferably made of a water-absorbent rubber material. Of course, the expansion and contraction member 9 in the present embodiment may be other expansion and contraction members. Since the bending direction of the tank 7 is away from the first space 6 in the present embodiment, the expansion and contraction member 9 provided in the tank 7 exchanges moisture only with the soil outside thereof. Before the infiltration irrigation starts, the humidity in the soil is low, the water in the expansion and contraction piece 9 is minimum, and the volume is also minimum. Along with the infiltrating irrigation of 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 piece 9 continuously absorbs water from the soil to expand; when the volume of the expansion and contraction member 9 expands to a certain extent, the groove body 7 is expanded and gradually approaches the sealing body 8 until the expansion and contraction member 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 an operator, the present embodiment further provides a first sensing assembly at a side of the tank body 7 facing the sealing body 8, and a second sensing assembly at a side of the sealing body 8 facing the tank body 7. So that the first sensing element will also be in contact with the second sensing element when the groove 7 and the sealing body 8 are in close contact.

The first sensing component and the second sensing component can be sensors, and the sensors are connected with external equipment through signals. After the first sensing assembly and the second sensing assembly are contacted, a signal of saturated soil humidity is transmitted to external equipment, and then an operator is reminded to close a water source switch to finish the infiltrating irrigation work.

This embodiment sets up inside the soil with automatically regulated subassembly, and expansion shrinkage subassembly sets up in the cell body of the outside crooked formation of first end of pipeline body for expansion shrinkage spare only can carry out the moisture exchange with soil, can not direct contact infiltration irrigation pipeline in the water that flows, can not be in the expansion state for a long time, and sensitivity is better. Along with the progress of infiltrating irrigation, the moisture in the soil increases, and soil humidity increases gradually, and expansion shrinkage body can absorb moisture from the soil for the volume constantly becomes big, and then drives the cell body and warp, and contact with the sealing body gradually, makes the water passageway close.

The groove body and the sealing body are respectively provided with a first induction component and a second induction component, when the first induction component and the second induction component are in contact, a closing signal can be sent out to remind an infiltrating irrigation operator of saturation of soil humidity, so that a water source switch is closed at a certain time, and infiltrating irrigation work is finished.

Therefore, the water-saving composite embedded infiltrating irrigation equipment of the embodiment can detect soil humidity through the first sensing assembly and the second sensing assembly, so that operators can better grasp the end time of infiltrating irrigation, optimize the irrigation effect of infiltrating irrigation and save water resources.

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 infiltrating irrigation pipeline 1 is fixedly connected with the automatic adjusting component through a connecting block 10 and a connecting groove. The shape of the connecting block can be trapezoid, boss shape and arbitrary bump shape.

Due to the effects of gravity and uniform speed such as arrangement of infiltrating irrigation holes, the water body oozed out of the infiltrating irrigation pipeline is more distributed in the deep position of the soil. Preferably, in order to ensure that the humidity of the soil contacted by the expansion and contraction member 9 is representative, the height of the tank 7 in this embodiment is at least higher than the height of the central axis of the infiltrating irrigation pipe 1, so that too low a height of the expansion and contraction member 9 can prevent premature expansion and deformation and make contact between the first sensing assembly and the second sensing assembly, and the infiltrating irrigation is finished prematurely, thereby influencing the irrigation effect.

As the moisture is absorbed and utilized by the crop, the humidity in the soil gradually decreases, and the moisture in the expansion and contraction member 9 is also reversely transferred to the soil, and the expansion and contraction member 9 itself is volume contracted. 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 piece 9 is reduced, a plurality of elastic reset pieces 11 are further arranged at the opening of the tank body 7 in the embodiment, so that the tank body 7 and the sealing body 8 are automatically separated after the soil humidity is reduced, and the water body 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 restoring element 11 can be in a block shape, a flake shape or a bar shape, and two ends of the elastic restoring element are respectively connected with two ends of the opening of the groove body 7, namely, two ends of the arc. When the expansion and contraction piece expands the groove body 7, the elastic restoring piece is also stretched and deformed; when the expansion and contraction piece dehydrates, the elastic reset piece recovers deformation, and drives the groove body to automatically reset and separate from the sealing body.

Further, in order to avoid the elastic restoring member 11 from affecting the water absorption and dehydration of the expansion and contraction member 9, a plurality of water permeable holes 111 are formed on the elastic restoring member 11.

Likewise, the automatic regulating assembly is arranged inside the soil and outside the infiltrating irrigation pipeline 1. The automatic adjusting component comprises a pipeline body 2, the same water body channel 3 is arranged on 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 first end 4 of the pipe body 2 is bent in a direction away from the first space 6 to form a groove 7, and the second end forms a sealing body 8.

This embodiment differs from embodiment 1 in that an anti-clogging structure 12 is also provided on the outside of the automatic adjustment assembly. The anti-clogging structure 12 may be a porous water permeable material such as a sponge, a non-woven fabric, or the like. 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.

The present embodiment also differs from embodiment 1 in that the present embodiment is provided with a plurality of water guiding structures 13 on the basis of the anti-clogging structure 12. Preferably, the water guiding structure 13 and the anti-blocking structure 12 are integrated, and the water guiding structure 13 and the anti-blocking structure 12 are made of the same material.
