Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural irrigation technology, in particular to a system for irrigating soil with frozen salt water. BACKGROUND

[0002] At present, in order to restore the ecology and realize the full use of saline-alkali land, it is necessary to wash salt in saline-alkali land and reduce the salt content in the soil. The conventional method is to wash salt with fresh water irrigation, but the fresh water resources are short in saline-alkali land, while the salt water resources are abundant. By extracting underground bitter salt water from saline-alkali land for irrigation in winter, the bitter salt water on the surface of the target soil is frozen into ice layer by using low temperature in winter, and the ice layer is formed. When spring comes, the ice layer with high salt content melts first and infiltrates underground, bringing the salt in the surface layer into the underground. In the process of gradually increasing air temperature, the fresh water ice layer melts last, and the soil surface is again driven by the infiltration of the melted fresh water ice layer, reducing the salt content in the soil surface.

[0003] In the process of underground bitter salt water irrigation, the floating impurities such as mud, salt particles and ice slurry in the water are easy to enter the nozzle of the sprinkler mechanism, which will cause the nozzle to be blocked and affect the smooth progress of irrigation. Although adding filter screen in the pipeline before the sprinkler mechanism can overcome this problem to some extent, if there are many impurities in the water, frequent shutdown is required for cleaning the filter screen, which will also seriously reduce the efficiency of irrigation.

Through the cooperation of the inclined surface block and the inclined surface ring, when the water pumping speed is increased, the water flow moves upward by impacting the inclined surface block, the gap between the inclined surface ring and the inclined surface block is increased, and at the same time, in the process of moving upward of the inclined surface block, the outer arc cover is driven to move upward through the sliding rod and the connecting disc, cooperates with the groove frame to increase the height of the blocked silt, and further optimizes the blocking effect.

[0051] The system for irrigating soil by using frozen brackish water provided by the above-mentioned embodiments of the present application is used in winter to extract underground brackish water from saline-alkali land for irrigation, and in winter, the low temperature in winter is used to make the brackish water on the target soil surface freeze and form an ice layer, and in spring, the ice layer with a high salt content melts first and infiltrates underground, bringing salt in the surface layer underground, and in the process of gradually increasing the air temperature, the freshwater ice layer melts last, and the soil surface is again driven by the infiltration after the melting of the freshwater ice layer, thereby reducing the salt content of the soil surface.

[0052] In the above-mentioned embodiments, when irrigating, the submersible pump 5 is placed in the underground brackish water, the underground brackish water is driven into the submersible pump 5 through the starting of the submersible pump 5 in winter, the brackish water storage mechanism 3 and the submersible pump 5 are connected through the communication pipe 6, the submersible pump 5 guides the underground brackish water into the brackish water storage mechanism 3 through the communication pipe 6, the underground brackish water enters the brackish water storage mechanism 3 for desilting, and the underground brackish water continuously stored in the brackish water storage mechanism 3 is finally sprayed out in cooperation with the sprinkling mechanism 2, thereby irrigating the land in winter, storing the underground brackish water on the target soil surface, and forming an ice layer on the target soil surface in cooperation with the low temperature in winter.

[0053] In the process of extracting underground brackish water by submersible pump 5, the underground brackish water enters through the water purification mechanism 4, and in the process of extracting underground brackish water, the underground brackish water enters the inside of the slot frame 410 from the oblique upper side of the outer arc cover 402 under the action of the submersible pump 5, and is preliminarily purified through the filter cover 411, blocking large impurities, so that the underground brackish water enters the inside of the filter cover 411, and is driven by the submersible pump 5 to surge upwards, entering the submersible pump 5 through the gap between the inclined block 408 and the inclined ring 407, and at the same time, when the submersible pump 5 increases the impulsive efficiency, the flow rate of the upward surging underground brackish water increases, so that the water flow impacts the inclined block 408, driving it upward, so that the gap between the inclined block 408 and the inclined ring 407 increases, and at the same time, in the process of moving upward on the inclined block 408, the connecting disc 404 is driven to slide along the outside of the slide column 405 through the slide rod 409, and in the process of moving upward on the connecting disc 404, the outer arc cover 402 is driven to move upward.

[0054] The extracted underground brackish water enters the water storage tank 31 through the connecting pipe 6, and impacts the inside of the water storage tank 31 from the bottom. In the process of the underground brackish water flowing into the water storage tank 31, the bottom plate 34 blocks the underground brackish water, so that the silt in the extracted brackish water is deposited downward during storage in the water storage tank 31, and the silt is driven by the deposition and impact flow of the underground brackish water to enter the sand storage box 32 for storage. At the same time, in the process of continuously storing the underground brackish water, the liquid level rises to the position of the grid plate 33, so that the grid plate 33 blocks the silt again, and the brackish water passes through the grid plate 33 to enter the gap between the inclined plate 37 and the grid plate 33, and then enters the other side of the top plate 35 and the bottom plate 34 through the water permeable groove in the center of the inclined plate 37.

When the brackish water passes over the top of the outer inclined cover 26, the brackish water enters the gap between the outer inclined cover 26 and the through-slot pipe 25 through the hollow slot on the surface of the hollow slot cover 27. When the liquid level is higher than the sealing ring 28, the buoyancy ring 29 in contact with the top of the sealing ring 28, and the buoyancy ring 29 is driven to move upward by the buoyancy after being in contact with the brackish water, opening the gap between the sealing ring 28 and the outer inclined cover 26, so that the brackish water flows downward through the gap, and then enters the through-slot pipe 25 through the through-slot on the outside of the through-slot pipe 25. In the process of continuously increasing the volume of the underground brackish water in the brackish water buffering mechanism 3, the brackish water surges upward from the through-slot pipe 25, and automatically enters the sprinkler 21 along the sleeve pipe 23 and the connecting pipe 22, so that the brackish water is sprayed out of the sprinkler 21, and the target soil is irrigated in winter without other power, saving cost.

[0056] In addition, the irrigation system of the present application is easy to maintain, for example, when the internal pipeline of the irrigation system is flushed with fresh water, the dead angle is small, the retention rate of silt is low, thus the problems such as pipeline corrosion caused by the residual salt-containing silt mixed in the salt water can be reduced or prevented, and the service life of the equipment is guaranteed.
