[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. An evaporation and condensation component is provided. Seawater is automatically transported into the evaporation pot. The focused sunlight heats the evaporation pot. The water in the seawater is heated to become water vapor and rises. The high-temperature water vapor rises and touches the low-temperature condensation cover to condense into water droplets. The absorbent mesh cotton quickly absorbs the condensed water droplets. Under the action of gravity, the absorbed water flows through the water-drawing cotton strip into the U-shaped groove. The seawater is desalinated by using sunlight, and sunlight is effectively utilized. The absorbent mesh cotton and the water-drawing cotton strip can quickly transfer the condensed water to prevent the water droplets from falling into the evaporation pot, thereby speeding up the preparation of fresh water.

[0021] Under the rotating connection of the universal joint and the rotating seat, the adjusting motor and the adjusting electric push rod are intermittently controlled according to the position of the sun. The adjusting electric push rod can drive the reflective focusing mirror to tilt at multiple angles, and the adjusting motor can drive the reflective focusing mirror to rotate, thereby realizing the multi-angle adjustment of the reflective focusing mirror, so that the sunlight reflected and focused by the reflective focusing mirror is always within the bottom surface of the evaporator, and the utilization rate of sunlight is higher. When there is no sunlight or the sunlight is weak, the supporting electric heating ring can assist in heating the evaporator to ensure the stable operation of the device.

[0022] The stirring motor drives the stirring rod and the scraper rod to stir the seawater inside the evaporator to prevent the precipitated crystal salt from covering the water surface and hindering the evaporation of water, thereby ensuring the operating stability of the device and accelerating the preparation of fresh water. Stirring the seawater will increase the contact area between water and surface air, further improving the efficiency of seawater desalination. When the water in the seawater inside the evaporator is completely evaporated, the rotating motor drives the supporting electric heating ring and the evaporator to rotate 180 degrees, and the residues remaining in the evaporator can be removed without manual cleaning, thereby reducing the intensity of manual labor. The scraper rod fits the inner wall of the evaporator, and can prevent residues such as crystal salt from sticking to the inner wall of the evaporator during the stirring process, thereby improving the cleaning effect.

[0023] 2. A resource recovery component is provided. During the evaporation process, the cold motor transports the cold water in the condensation pool into the cold water hood. The cold water entering the cold water hood can cool down the condensation hood and accelerate the condensation speed of water vapor. The top surface of the condensation hood is evenly welded with heat exchange plates. The heat exchange plates increase the heat conduction area, further accelerate the condensation speed, and accelerate the fresh water preparation speed. Under the action of heat conduction, the cold water temperature rises, and the water after heat exchange flows through the return cold branch pipe into the sealed box. The water after heat exchange can heat the seawater flowing through the heat exchange tube. When the seawater is transported to the inside of the evaporator, the initial temperature of the seawater is higher, and the sunlight can heat the water to the boiling point more quickly, which accelerates the fresh water preparation speed and also recycles the heat energy;

[0024] When the water in the seawater inside the evaporator is completely evaporated, the rotating cylinder drives the supporting tube and the evaporator to rotate forty-five degrees, and the lifting electric push rod drives the condensation hood to rise. The electric moving seat drives the conveyor belt to the bottom of the evaporator. The evaporator rotates to pour the residual crystallized salt and other residues inside into the top of the conveyor belt. The electric moving seat cooperates with the conveyor belt to transfer the residues, which is convenient for recycling.

[0025] In summary, the heat of sunlight is effectively utilized by using reflective focusing mirrors in the evaporation and condensation components, and the heat of hot water is utilized in the resource recovery components. The two components cooperate with each other, and the energy utilization rate of the device is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the condensation cover 216 is bonded with a water-absorbing mesh cotton 219, and the outer side of the water-absorbing mesh cotton 219 is connected to a plurality of water-inducing cotton strips 220. The bottom of the water-inducing cotton strips 220 is located at the top of the U-shaped groove 217. The water-absorbing mesh cotton 219 can quickly absorb the condensed water droplets. Under the action of gravity, the absorbed water can flow through the water-inducing cotton strips 220 into the U-shaped groove 217. The fresh water inside the U-shaped groove 217 flows through the fresh water drain pipe 218 into the fresh water collection box 221, and is finally discharged through the discharge pipe 222. The discharged water is the prepared fresh water. The seawater is desalinated by using sunlight, and there is no need to use electricity to heat the evaporator 211 in real time.

[0054] During the evaporation process, the cold water supply motor 311 delivers the cold water in the condensation pool 310 into the cold water supply box 309, and then flows through the cold water supply branch pipe 314 into the cold water cover 313. The cold water entering the cold water cover 313 can cool down the condensation cover 216 and accelerate the condensation speed of water vapor. The top surface of the condensation cover 216 is evenly welded with heat exchanger plates 315. The heat exchanger plates 315 increase the heat conduction area, further accelerate the condensation speed, and accelerate the fresh water preparation speed. Under the action of heat conduction, the cold water temperature rises, and the water after heat exchange flows through the return cold water cover 216. The branch pipe 316 enters the sealed box 302. When the seawater subsequently flows through the heat exchange tube 304, the water after heat exchange can heat the seawater flowing through. When the seawater is transported to the evaporator 211, the initial temperature of the seawater is higher. The sunlight can heat the water to the boiling point more quickly, which speeds up the preparation of fresh water and recycles the heat energy. When there is no sunlight or the sunlight is weak, the support electric heating ring 210 is energized, and the support electric heating ring 210 can assist in heating the evaporator 211 to ensure the stable operation of the device.

[0055] When evaporating seawater, the condensation cover 216 covers the top of the evaporation pot 211, and the stirring motor 223 is started. The stirring motor 223 drives the stirring shaft 224, the stirring rod 225 and the scraper rod 226 to rotate. The stirring rod 225 and the scraper rod 226 can stir the seawater inside the evaporation pot 211 to prevent the precipitated crystal salt from covering the water surface and hindering the evaporation of water, thereby accelerating the evaporation rate. At the same time, stirring the seawater will increase the contact area between the water and the surface air, further accelerating the evaporation rate, thereby further accelerating the fresh water preparation rate. The scraper rod 226 is in contact with the inner wall of the evaporation pot 211. During the stirring process, it can prevent the residue from adhering to the inner wall of the evaporation pot 211, and prevent the residue from being retained inside the evaporation pot 211 when the residue is discharged later;

[0056] When the water in the seawater inside the evaporator 211 is completely evaporated, the rotating cylinder 321 drives the support tube 201 and the evaporator 211 to rotate forty-five degrees. Here, the evaporator 211 is separated from the focused sunlight spot, and the lifting electric push rod 213 drives the condensation cover 216 to rise, and the scraper rod 226 is separated from the inside of the evaporator 211. Then, the lifting cylinder 324 drives the conveyor belt 325 to rise, and the electric moving seat 323 drives the conveyor belt 325 to move to the bottom of the evaporator 211. The rotating motor 209 drives the supporting electric heating ring 210 and the evaporator 211 to rotate one hundred and eighty degrees. The crystallized salt and other residues remaining in the evaporator 211 are poured into the top of the conveyor belt 325, without manual cleaning, reducing the labor intensity. After all the residues are poured out, the rotating cylinder 321 drives the evaporator 211 to return to its original position, and the conveyor belt 325 transfers the residues for the next step of processing;

[0057] The reflective focusing mirror 230 is used in the evaporation condensation component 2 to effectively utilize the heat of sunlight, and the heat of the hot water exchange is utilized in the resource recovery component 3. The two components cooperate with each other, and the energy utilization rate of the device is higher.
