Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Referring to the attached drawings of the specification Figures 1-4 , a solar seawater desalination device for tracking the sun's azimuth of the present invention includes an equipment main body 1. For details, see Figure 4 , a first motor 2 is fixedly installed inside the equipment main body 1. The output shaft of the first motor 2 is fixedly connected to a gear 3. The outer wall of the gear 3 is engaged with a toothed ring 4. The toothed ring 4 is rotatably connected to the top of the equipment main body 1. The top of the toothed ring 4 is fixedly connected to a mounting plate 5. The inside of the mounting plate 5 is rotatably connected to a fixed frame 6. A photovoltaic panel 7 is fixedly installed inside the fixed frame 6. The outer wall of the fixed frame 6 is rotatably connected to a connecting rod 8. The outer wall of the connecting rod 8 is rotatably connected to a slider 9. The slider 9 is slidably connected inside the mounting plate 5. The inside of the slider 9 is threadedly connected to a threaded rod 10. The threaded rod 10 is rotatably connected inside the mounting plate 5. A second motor 11 is fixedly installed inside the mounting plate 5. The threaded rod 10 is fixedly connected to the end of the output shaft of the second motor 11;

[0022] , a water inlet pipe 12 is fixedly connected inside the equipment main body 1. One end of the water inlet pipe 12 communicates with a collecting member 13. The collecting member 13 is fixedly installed inside the equipment main body 1. For details, see Figure 3 , a connecting member 14 communicates with the outer wall of the collecting member 13. A sealing block 15 is slidably connected inside the connecting member 14. A spring 16 is fixedly installed at the bottom of the sealing block 15. The spring 16 is fixedly installed inside the connecting member 14. The outer wall of the connecting member 14 is fixedly connected to an evaporation tank 17. A plurality of heating plates 18 (there is a gap between the heating plates 18 and the bottom surface of the inner wall of the evaporation tank 17 for seawater to flow through) are fixedly installed inside the evaporation tank 17. A guiding member 19 is arranged at the top of the evaporation tank 17. The evaporation tank 17 and the guiding member 19 are arranged at the bottom of the collecting member 13. A drain pipe 20 communicates with the outer wall of the guiding member 19. The drain pipe 20 is fixedly installed inside the equipment main body 1.

[0023] It should be noted that when the photovoltaic panel 7 generates electricity under the sun's irradiation, after the sun changes its position over time, the control board inside the device main body 1 will control the first motor 2 and the second motor 11 to work. The first motor 2 drives the gear 3 to rotate, and then the gear 3 drives the toothed ring 4 to rotate, enabling the toothed ring 4 to finally drive the photovoltaic panel 7 to rotate and change its direction through the mounting plate 5. When the second motor 11 works, it drives the threaded rod 10 to rotate, causing the threaded rod 10 to drive the connecting rod 8 to move through the slider 9, and then the connecting rod 8 pushes the fixed frame 6 to rotate, enabling the fixed frame 6 to drive the photovoltaic panel 7 to change its pitch angle. By changing the direction and angle of the photovoltaic panel 7, the photovoltaic panel 7 can always follow the sun's trajectory, keep aiming at the sun, maintain a high power generation efficiency, increase the power generation of the photovoltaic panel 7, thereby saving the external power supply of the seawater purification device and achieving an energy-saving effect. It should be noted that when night falls, the control board inside the device main body 1 will control the first motor 2 and the second motor 11 to reset, and finally reset the mounting plate 5 and the photovoltaic panel 7 to prevent the mounting plate 5 and the photovoltaic panel 7 from rotating continuously, resulting in the connection wires of the seawater desalination device being twisted off;

[0024] Furthermore, when encountering strong winds, the detector on the device main body 1 will transmit a signal to the control board, causing the control board to control the second motor 11 to work and reset. The second motor 11 drives the threaded rod 10 to reverse, and then the threaded rod 10 pulls the connecting rod 8 to reset through the slider 9, enabling the connecting rod 8 to drive the photovoltaic panel 7 to be retracted to the top of the mounting plate 5 through the fixed frame 6, preventing the photovoltaic panel 7 from being blown by the strong wind and causing damage;

[0025] Furthermore, when the staff fills the seawater desalination device with seawater through the water inlet pipe 12 by an external water pipe, the seawater will first enter the inside of the collecting member 13 through the water inlet pipe 12. When the seawater desalination device is working, the heating plate 18 will heat the seawater inside the evaporation tank 17, causing the seawater to heat up and evaporate. Then, the evaporated water vapor rises and adheres to the bottom of the collecting member 13. The heat in the water vapor will be transferred to the seawater inside the collecting member 13 to heat the seawater inside the collecting member 13, thereby achieving the effect of preheating the seawater using waste heat and causing the water vapor temperature to drop and condense. After the water vapor temperature drops and condenses, it will slide down along the arc surface at the bottom of the collecting member 13 into the inside of the guiding member 19, enabling the guiding member 19 to drain the water through the drain pipe 20 out of the inside of the seawater desalination device to achieve the effect of desalinating the seawater;

[0026] Further, when the amount of seawater in the evaporation tank 17 is insufficient, the staff can continue to drain seawater into the interior of the collection member 13 through the water inlet pipe 12, so that the heated seawater in the collection member 13 enters the interior of the connecting member 14 to squeeze the sealing block 15. As a result, the sealing block 15 descends along the interior of the connecting member 14 to open the opening and squeeze the spring 16 to contract, allowing the heated seawater in the collection member 13 to be discharged into the interior of the evaporation tank 17 for continuous evaporation. When the staff stops pouring in seawater, the pressure inside the collection member 13 drops, and the spring 16 will push the sealing block 15 upward to reseal the opening, preventing the seawater inside the collection member 13 from being discharged into the interior of the evaporation tank 17 through the opening of the connecting member 14.

[0027] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense.
