Referring to Figure 1 The energy-saving seawater desalination device comprises a high-pressure cleaning machine 1, a reverse osmosis membrane 2, a solar panel 3 and a storage battery 4. The high-pressure cleaning machine 1 comprises a cleaning machine body 11 and a connecting column 12 fixed on the cleaning machine body 11. The reverse osmosis membrane 2 is installed on the cleaning machine body 11, and the water inlet of the reverse osmosis membrane 2 and the water outlet of the cleaning machine body 11 are communicated.

[0035] Referring to Figures 1-4An elastic tube 5 is fixed on the main body 11 of the cleaning machine. The elastic tube 5 is connected to the water inlet of the main body 11 of the cleaning machine. A movable plate 6 is slidably connected to the connecting column 12. The movable plate 6 is located on the shaded side of the solar panel 3 and is parallel to the solar panel 3. The movable plate 6 includes a plate body 61 and an extension plate 62. The plate body 61 is sleeved on the outside of the connecting column 12 and slidably connected to the connecting column 12. The plate body 61 slides closer to or away from the solar panel 3. The elastic tube 5 is located on the side of the plate body 61 that is closer to the solar panel 3 and is connected to the movable plate 6. An adjusting block 7 is threadedly connected to the connecting column 12. The adjusting block 7 is located on the side of the plate body 61 that is away from the solar panel 3 and is sleeved on the outside of the connecting column 12. The adjusting block 7 and the plate body 61 are rotatably connected. The rotation axis of the adjusting block 7 and the plate body 61 is parallel to the sliding direction of the plate body 61.

[0036] See Figures 1-5 In this embodiment, the elastic tube 5 is made of silicone. A limiting block 8 is fixed on the plate 61. A limiting groove 121 for accommodating the limiting block 8 is provided on the outer side wall of the connecting column 12. The limiting block 8 slides along the sliding direction of the plate 61 and is connected to the limiting groove 121. The limiting block 8 is abutted against by the inner wall of the limiting groove 121 to prevent relative rotation between the plate 61 and the connecting column 12.

[0037] See Figures 1-6 The extension plate 62 is located above the solar panel 3 and fixed to one end of the plate body 61. The plate body 61 has an installation cavity 611, and a weight ball 9 is horizontally slidably connected in the installation cavity 611. The plate body 61 also has two cavities 612, which are located on both sides of the installation cavity 611 along the sliding direction of the weight ball 9 and are connected to the installation cavity 611. Several air outlets 621 are provided on the outer wall of the extension plate 62. The air outlets 621 are located on the side of the solar panel 3 away from the plate body 61 and are distributed at intervals along the length of the solar panel 3. The air outlets 621 are all connected to the cavities 612. The orientation of each air outlet 621 forms an angle of 30-45° with the surface of the solar panel 3.

[0038] See Figures 1-7 Each cavity 612 has a slidingly connected insert 10. The insert 10 fits against the inner peripheral wall of the cavity 612 and slides closer to or away from the heavy ball 9. An elastic element 13 is fixed on the plate 61. The elastic element 13 is located in the cavity 612 and on the side of the insert 10 closer to the heavy ball 9. The opposite ends of the elastic element 13 are fixedly connected to the insert 10 and the inner wall of the cavity 612 near the mounting cavity 611, respectively. The elastic element 13 pulls the insert 10 tight, so that the insert 10 tends to move closer to the heavy ball 9. In this embodiment, two elastic elements 13 are installed in each cavity 612. The two elastic elements 13 are located on both sides of the cavity 612, and the elastic element 13 is a spring.

[0039] See Figures 1-8A plurality of connecting components 14 are provided on the side of the plate 61 near the solar panel 3. The plurality of connecting components 14 are evenly spaced along the transverse and longitudinal directions. Each connecting component 14 includes a clamping band 141, a positioning element 142, and a plurality of positioning elements 143. One end of the clamping band 141 is hinged to the plate 61, and the hinge axis of the clamping band 141 is parallel to the rotation axis of the adjusting block 7 and the plate 61. The positioning element 142 includes a connecting part 1421 and a locking part 1422. The connecting part 1421 is fixed to the other end of the clamping band 141, and the locking part 1422 is fixed to the side of the connecting part 1421 away from the clamping band 141. The plurality of positioning elements 143 surround the clamping band 141. The outer periphery of 1 is evenly spaced in the circumferential direction, and the positioning component 2 143 is fixed on the plate 61. The outer side wall of the positioning component 2 143 away from the plate 61 is provided with a slot 1431 for the positioning component 1 142 to be inserted. When the positioning component 1 142 is inserted into the slot 1431, the connection part 1421 and the connecting band 141 are located in the slot 1431, and the connecting band 141 and the plate 61 are spliced ​​to form a through hole 15 for the elastic tube 5 to pass through. The connecting part 1422 abuts against the inner wall of the slot 1431 to position the connecting band 141. In this embodiment, the material of the connecting band 141 is suede, which has the ability to deform, and the positioning component 2 143 is a positioning block.

[0040] In actual use, when the elastic tube 5 is damaged, the movable positioning part 142 is removed from the slot 1431, releasing the positioning state of the clamping band 141. Then, the damaged elastic tube 5 is removed, and a new elastic tube 5 is taken. The elastic tube 5 is placed between the hinge point of the clamping band 141 and the positioning part 143. Then, the clamping band 141 is moved so that it presses the elastic tube 5 against the plate 61 and the positioning part 142 is inserted into the slot 1431 on the corresponding positioning part 143. The clamping part 1422 abuts against the inner wall of the slot 1431, thus positioning the clamping band 141. At this time, the elastic tube 5 is located in the through hole 15. After the positioning of the clamping band 141 on each connecting component 14 through which the elastic tube 5 passes is completed, the connection and shaping of the new elastic tube 5 on the movable plate 6 is completed.

[0041] The implementation principle of an energy-saving seawater desalination device according to an embodiment of this application is as follows:

[0042] The solar panel 3 charges the battery 4, and the battery 4, which is charged by the solar panel 3, continuously supplies power to the high-pressure washer 1. This allows the high-pressure washer 1 to pump seawater into the reverse osmosis membrane 2 under high pressure for filtration to obtain fresh water. By using solar energy instead of electricity, it is more energy-efficient and environmentally friendly, and reduces power consumption, which helps to reduce the cost of long-distance voyages.

[0043] Increased temperature will significantly reduce the power generation efficiency of solar panel 3. When the temperature is high, the adjusting block 7 can be twisted. The adjusting block 7 drives the movable plate 6 to move closer to solar panel 3, so that the elastic tube 5 is in close contact with solar panel 3. During the operation of the high-pressure cleaner 1, the seawater flowing in the elastic tube 5 carries away the heat of solar panel 3 to achieve cooling, thereby improving the power generation efficiency of solar panel 3.

[0044] Depending on the degree of temperature rise of the solar panel 3, the adjusting block 7 can be twisted further, so that the elastic tube 5 is squeezed by the solar panel 3 and the movable plate 6, increasing the contact area between the elastic tube 5 and the solar panel 3, and further improving the cooling effect of the elastic tube 5 on the solar panel 3.

[0045] If the temperature is low, the adjusting block 7 can be twisted. The adjusting block 7 will move the movable plate 6 away from the solar panel 3, so that the elastic tube 5 is away from the solar panel 3. The elastic tube 5 will recover under the action of elasticity, which will reduce the aging of the elastic tube 5 under long-term compression and help extend the service life of the elastic tube 5.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
