A salt water inlet 7 is arranged on the side wall of the evaporation box 1; the box cover 2 is sealed and arranged on the top of the evaporation box 1; the first condenser 3 is arranged on the box cover 2; the water collecting trough 4 is arranged obliquely in the evaporation box 1, and a salt water evaporation channel is left between the water collecting trough 4 and the evaporation box 1. The water collecting trough 4 is located below the box cover 2 and is used to collect water drops dripping from the box cover 2; the water collecting box 5 is arranged outside the evaporation box 1, and the lower end of the water collecting trough 4 is connected to the water collecting box 5; the inlet end of the infiltration irrigation main pipe 6 is connected to the water collecting box 5.

[0035] Furthermore, if Figure 1 As shown, it also includes a water guide pipe 8, which is located outside the evaporation box 1, and the lower end of the water collecting tank 4 is connected to the water collecting tank 5 by means of the water guide pipe 8. The water collecting tank 4 is connected to the water collecting tank 5 by means of the water guide pipe 8, so that the condensed fresh water falls into the water collecting tank 4 and then enters the water collecting tank 5 through the water guide pipe 8, which can reduce the requirements for the relative position of the evaporation box 1 and the water collecting tank 5, and is more convenient to install.

[0036] Furthermore, if Figure 1As shown, the second condenser tube 9 and the delivery pump 10 are also included. The second condenser tube 9 is wound around the outer periphery of the water pipe 8. The inlet end of the first condenser tube 3 is connected to the outlet end of the second condenser tube 9; the inlet end of the second condenser tube 9 is connected to the delivery pump 10. The delivery pump 10 delivers low-temperature water to the second condenser tube 9 and the first condenser tube 3, so that the box cover 2 and the water pipe 8 maintain a low temperature, ensuring that the evaporated water in the evaporation box 1 can smoothly enter the water collecting box 5, which can improve the desalination efficiency of salt water.

[0037] Furthermore, if Figure 1 As shown, a solar panel 11 is also included, and the solar panel 11 is electrically connected to the delivery pump 10. The electric energy generated by the solar panel 11 is used to power the delivery pump 10, which can make full use of solar energy and is more environmentally friendly and energy-saving.

[0039] Furthermore, if Figure 1 and Figure 3 As shown, the box cover 2 also includes a sealing cover 13, and a rainwater collection channel 14 is provided on the box cover 2. The sealing cover 13 is provided at the upper end of the rainwater collection channel 14. The sealing cover 13 and the box cover 2 are detachably connected, and the lower end of the rainwater collection channel 14 extends above the water collecting tank 4. When it is not raining, the sealing cover 13 is installed on the box cover 2, and the rainwater collection channel 14 is sealed by the sealing cover 13. In the closed evaporation box 1, the salt water evaporates under the solar radiation, and the evaporated water rises through the salt water evaporation channel between the water collecting tank 4 and the evaporation box 1. After encountering the box cover 2, it condenses into water on the inner surface of the box cover 2 under the condensation action of the first condensation tube 3. The water enriched on the inner surface of the box cover 2 drops and flows into the water collecting tank 4, and finally gathers in the water collecting tank 5. When it rains, the sealing cover 13 is separated from the box cover 2, so that the rainwater enters the rainwater collection channel 14 on the box cover 2, and then enters the water collecting tank 5 through the water collecting tank 4. This can not only make up for the low efficiency of salt water desalination in rainy weather, but also regulate rainwater to achieve the goal of "summer water for spring use", thereby achieving seasonal turnover of rainfall and improving water utilization rate.

[0040] Furthermore, if Figure 1 and Figure 3 As shown, a filter screen 15 is also included, which is arranged on the box cover 2 and located in the rainwater collection channel 14. The rainwater in the rainwater collection channel 14 is filtered by the filter screen 15 and then enters the water collection tank 4, which can reduce the probability of debris, dust, etc. entering the water collection tank 4.

[0041] Furthermore, if Figure 1 As shown, it also includes an infiltration irrigation branch pipe 16, the number of which is at least two, all of which are arranged along the length direction of the infiltration irrigation main pipe 6, and the inlet end of the infiltration irrigation branch pipe 16 is connected to the infiltration irrigation main pipe 6. The infiltration irrigation branch pipe 16 cooperates with the infiltration irrigation main pipe 6 to expand the coverage of infiltration irrigation and improve irrigation efficiency.

[0042] Furthermore, if Figure 1 As shown, it also includes a switch valve 17, and the inlet end of the infiltration irrigation main pipe 6 is connected to the water collecting box 5 by means of the switch valve 17. The switch valve 17 can be opened or closed according to actual needs, and the operation is simple and convenient.

[0043] Furthermore, if Figure 1 As shown, it also includes a flow meter 18 and a pressure regulator 19.

The flow meter 18 can detect the flow in the infiltration irrigation main pipe 6 in real time, and the pressure regulator 19 can be used to adjust the pressure in the infiltration irrigation main pipe 6 to better meet the irrigation demand.

[0044] In this embodiment, the evaporation box 1 is a barrel-shaped structure, the box cover 2 is funnel-shaped, the lower end of the box cover 2 is inserted into the evaporation box 1, and the upper end of the box cover 2 is placed on the evaporation box 1. The hollow structure of the funnel-shaped box cover 2 is the rainwater collection channel 14, and the sealing cover 13 can overlap and seal with the upper end opening of the funnel-shaped box cover 2. The salt water inlet 7 is located at the upper end of the side wall of the evaporation box 1. The water collecting tank 4 is a semi-open pipe, and a salt water evaporation channel is left between the water collecting tank 4 and the evaporation box 1. The water collecting tank 4 is located below the box cover 2. The water collecting tank 4 and the water guide pipe 8 are an integrated structure, and the lower end of the water collecting tank 4 is connected to the water collecting box 5 through the water guide pipe 8. In order to facilitate the disassembly and assembly of the first condenser tube 3, the box cover 2 includes an inner funnel and an outer funnel. The upper end of the inner funnel is placed on the evaporation box 1, and the outer funnel is located at the periphery of the side wall of the inner funnel. The first condenser tube 3 is located between the inner funnel and the outer funnel. The upper end of the inner funnel is provided with a through hole for passing the first condenser tube 3. The water collecting tank 5, the infiltration irrigation main pipe 6 and the infiltration irrigation branch pipe 16 are all buried in the soil. The top surface of the water collecting tank 5 is reserved with a water inlet and an air inlet 20 so that the water in the water collecting tank 5 can flow out smoothly. The inlet end of the infiltration irrigation main pipe 6 is connected to the water collecting tank 5 through a switch valve 17. The infiltration irrigation main pipe 6 is connected with a flow meter 18, a pressure regulator 19 and a group of infiltration irrigation branch pipes 16. The water collecting tank 5 is buried in the soil and the natural temperature difference is used to improve the efficiency of salt water desalination.

[0045] The temperature of the salt water in the field drainage ditch is lower than that of the water in the evaporation box 1. The inlet end of the delivery pump 10 and the outlet end of the first condenser tube 3 are both placed in the drainage ditch. Under the action of the delivery pump 10, the salt water in the drainage ditch passes through the second condenser tube 9 and the first condenser tube 3 in sequence and then returns to the drainage ditch. When flowing through the first condenser tube 3, the evaporated water in the evaporation box 1 is cooled and condensed, so that the salt water in the drainage ditch can be recycled and cost can be saved. When it is not raining, the solar water pump is used to absorb the salt water in the field drainage channel, and the salt water is transported to the evaporation box 1 through the salt water inlet 7, and then the salt water inlet 7 is closed, and the sealing cover 13 is installed on the box cover 2. The rainwater collection channel 14 is sealed by the sealing cover 13. In the closed evaporation box 1, the salt water evaporates under the solar radiation, and the evaporated water rises through the salt water evaporation channel between the water collecting tank 4 and the evaporation box 1. After encountering the box cover 2, it condenses into water on the inner surface of the box cover 2 under the condensation of the salt water in the first condensation pipe 3. The water enriched on the inner surface of the box cover 2 drops into the water collecting tank 4, and then passes through the water guide pipe 8 and finally collects in the water collecting box 5. When it rains, the sealing cover 13 is separated from the box cover 2, so that the rainwater enters the rainwater collection channel 14 on the box cover 2, and after being filtered by the filter screen 15, it enters the water collecting tank 4, and then enters the water collecting tank 5 through the water collecting tank 4 and the water guide pipe 8. When the weather is dry, the switch valve 17 is opened, and the fresh water in the water collecting tank 5 can be used to irrigate the fields through the infiltration irrigation main pipe 6 and the infiltration irrigation branch pipe 16.

[0046] The bottom diameter of the evaporation box is 1m, the height is 1.2m, the salt water inlet 7 is located on the side wall 1.0m from the bottom, and the inner diameter of the upper edge of the funnel-shaped box cover 2 is 1.0m, that is, the maximum rainwater collection area is 0.785m 2 The diameter of the funnel neck is 0.03m and the length is 0.1m. The water collecting tank 4 is a semi-open tube with a semicircular end face. The diameters of the water collecting tank 4 and the water guide pipe 8 are both 0.04m. The angle between the water collecting tank 4 and the horizontal plane is 10°. The first condenser tube 3 and the second condenser tube 9 are both thin hoses with a diameter of 0.01m. The size of the water collecting tank is 2.0m (length) × 2.0m (width) × 0.5m (height). When the water collecting tank is full, it can provide 60m 2 For example, in the case of emergency irrigation of wheat in spring, the main and branch irrigation pipes are buried at a depth of about 0.4m, and the water injection is stopped when the water level in the evaporation box is 0.7m. On sunny days, the average daily water production from June to August is 1.96kg / m 2 According to the comprehensive calculation of rainfall in Huanghua area from June to August in 2022 when the rainfall is greater than 1 mm, the infiltration irrigation device can collect at least 1.92m 3 rainwater.

[0047] Solar desalination technology is an ecological and energy-saving reliable way to alleviate the shortage of freshwater resources. It makes full use of the abundant saltwater resources in the coastal area in an environmentally friendly and energy-saving way. The area has sufficient sunlight and abundant saltwater resources. Relying on the simple infiltration irrigation devices available in the field, the sun can be used to evaporate water, and the solar energy can drive the flow of cold water to accelerate steam condensation, so as to maximize the use of solar energy. It can improve the utilization rate of saltwater resources in the saline-alkali area around the Bohai Sea, which is of great significance to alleviating spring drought and improving the utilization rate of water resources.

[0048] The spring in the saline-alkali area around Bohai Sea is dry and windy, which limits the growth of crops. In summer, it is hot and rainy, and 80% of the rainfall occurs from July to September. The excess rainwater cannot be fully utilized by crops, resulting in low utilization rate of freshwater resources. The infiltration irrigation device can not only make up for the low efficiency of salt water desalination in rainy weather, but also regulate rainwater to achieve the purpose of "summer water for spring use". In the spring drought period, timely root irrigation is carried out to achieve the purpose of seasonal turnover of rainfall, improve water utilization rate, and increase grain production.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
