Description

Technical Field

[0001] The present application relates to the field of seawater desalination, and in particular to a small seawater desalination device. Background Art

[0002] Fresh water resources are necessary for people to survive, especially for those who go out to sea. They need to reserve a large amount of fresh water to meet their needs. When the fresh water is insufficient or used up, it will directly cause many inconveniences for the sea workers and seriously affect people's lives and health. At present, the working process of the existing seawater desalination device is affected by the sea breeze and is unstable. When desalinating seawater, a large amount of energy is consumed, resulting in energy waste.

[0003] In order to solve the problem of insufficient energy at sea, the existing technology also sets up solar panels to collect solar energy, but the collection effect is not good, and the harsh environment at sea makes the solar panels easily damaged, resulting in increased costs. Summary of the invention

[0004] In order to solve the problem of insufficient offshore energy and reduce the probability of solar panels being easily damaged, the present application provides a small seawater desalination device.

[0005] The small-scale seawater desalination device provided in this application adopts the following technical solution: A small seawater desalination device comprises: a seawater desalination system, an energy collection system for providing energy to the seawater desalination system, and a fresh water storage system for storing water treated by the seawater desalination device; The seawater desalination system comprises: The seawater pretreatment mechanism has a multi-stage filter screen inside to filter out large particles of impurities in the seawater; Reverse osmosis membrane treatment mechanism, used to remove impurities from seawater; A mineralization mechanism for adding minerals to the filtered seawater; The energy collection system comprises: A solar energy collection mechanism, used for collecting solar energy; An adjusting mechanism, used for adjusting the installation angle of the solar energy collecting mechanism; The solar energy detection mechanism is used to detect the angle of the sun and drive the adjustment mechanism to operate according to the detected data, so that the solar energy collection mechanism always faces the sun; A wind collecting mechanism, used for collecting wind power; A retracting mechanism, connected to the wind collecting mechanism, and used to control the extension or retraction of the wind collecting mechanism; A wind force detection mechanism is used to detect the strength of the wind force and drive the retracting mechanism to operate according to the detected data, so as to control the wind force collection mechanism to extend to collect the wind force or control the wind force collection mechanism to retract to resist the strong wind force; A protective mechanism is arranged around the solar energy collecting mechanism and the wind power collecting mechanism, and is used to automatically cover the solar energy collecting mechanism and the wind power collecting mechanism when rain or snow occurs outside; The fresh water storage system has a detection element installed inside, which is used to control the seawater desalination system to start when the amount of water stored in the fresh water storage system is less than a set value, and control the seawater desalination system to stop when the amount of water stored in the fresh water storage system is higher than the set value.

[0006] By adopting the above technical solution, the solar energy can be collected by the solar energy collection mechanism, and the solar energy detection mechanism is set up so that the position information of the sun can be detected in real time, and the adjustment mechanism can be controlled to adjust the direction of the solar panel through the detected sun position information to ensure that the solar panel is always facing the sun, so that the collection efficiency of solar energy is higher; at the same time, the wind power collection mechanism can collect the wind power on the sea, and the wind power detection mechanism can detect the wind power on the sea surface, and control the wind power collection mechanism to retract when the external wind is strong, thereby reducing the probability of the wind power collection mechanism being damaged by the external strong wind. If there is rain or snow outside, the protective mechanism will automatically cover the solar power collection mechanism and the wind power collection mechanism to reduce the probability of damage to the solar power collection mechanism and the wind power collection mechanism. The electricity collected by the solar energy collection mechanism and the wind power collection mechanism will be supplied to the seawater desalination system, and the large particles of impurities in the seawater will be filtered and removed through the seawater pretreatment mechanism. The water with impurities removed will reach the reverse osmosis membrane treatment mechanism, thereby treating the suspended particles and salt in the water. The treated water will reach the mineralization mechanism, and minerals will be added through the mineralization mechanism to ensure that the minerals contained in the water meet the needs of the human body. The treated water will be stored in the fresh water storage system.

[0007] Optionally, the solar energy collection mechanism includes a solar panel for collecting solar energy and a first storage battery connected to the solar panel for storing electricity collected by the solar panel.

[0011] Optionally, the mounting plate is overall U-shaped, the back of the solar panel is hinged to two opposite sides of the mounting plate through a connecting plate, and the first driving assembly includes a first electric push rod hinged to the connecting plate and a closed end of the mounting plate; The second driving assembly includes a driving motor for driving the mounting plate to rotate.

[0012] By adopting the above technical solution, the first electric push rod can drive the solar panel to rotate around the hinge axis with the mounting plate, and the driving motor can drive the solar panel to rotate, thereby achieving adjustment at multiple angles.

[0013] Optionally, the solar energy detection mechanism includes a solar sensor, a linear displacement sensor for detecting the extension and retraction amount of the first electric push rod is installed on the first electric push rod, and an encoder for detecting the rotation amount of the output shaft of the drive motor is installed on the output shaft of the drive motor. The solar sensor, the first electric push rod, the linear displacement sensor, the drive motor, and the encoder are all connected to a controller. When the solar sensor detects the azimuth angle of the sun, the controller controls the extension and retraction of the first electric push rod to a set distance, and the linear displacement sensor is used to detect the extension and retraction distance of the first electric push rod; the controller controls the rotation of the drive motor to a set angle, and the encoder is used to detect the rotation angle of the drive motor.

[0014] By adopting the above technical solution, the angle of the solar panel can be automatically adjusted, so that the solar panel can always face the sun, making the solar energy collection efficiency higher.

[0015] Optionally, the wind collection mechanism includes a mounting rod, a plurality of support rod groups hinged on the outer wall of the mounting rod, and blades hinged on one end of the support rod group away from the mounting rod; the support rod group includes a first rod hinged between the mounting rod and the blade and a second rod hinged between the mounting rod and the blade, the first rod and the second rod are arranged in parallel, and the retraction mechanism includes a sliding cylinder slidably connected to the mounting rod, a retraction rod hinged between the sliding cylinder and the second rod, and a retraction assembly that drives the sliding cylinder to slide on the mounting rod.

[0016] By adopting the above technical solution, under normal circumstances, the external wind can directly drive the blades to rotate, thereby realizing the collection of wind force. When strong winds appear outside, the sliding cylinder can be driven to slide through the contraction component to realize the retraction of the blades, thereby reducing the probability of the blades being damaged by strong winds.

[0017] Optionally, the mounting rod includes a fixed rod fixed to the ground and a mounting tube slidably connected to the fixed rod, the sliding tube is slidably mounted on the mounting tube, the contraction assembly includes a driving ring rotatably connected to the sliding tube and a second electric push rod fixed to the driving ring for driving the driving ring to move, and a first fixing ring is fixed to the mounting tube to limit the sliding tube from sliding down to an extreme position.

[0018] By adopting the above technical solution, the installation rod can be retracted while the blades are folded, thereby reducing the overall floor space.

[0019] Optionally, a second fixing ring is fixedly connected to the mounting cylinder to limit the sliding cylinder from sliding to an extreme position, a blocking block is fixedly connected to one end of the second fixing ring facing the sliding cylinder, a slot for the blocking block to be embedded is provided on the end wall of the sliding cylinder, the wind collection mechanism also includes a generator and a second battery connected to the generator, a first driving bevel gear is fixedly connected to the sliding cylinder, a first driven bevel gear meshing with the first driving bevel gear is fixedly connected to the input shaft of the generator, when the blocking block is embedded in the slot, the first driving bevel gear is meshed with the first driven bevel gear; when the sliding cylinder abuts against the second fixing ring, the first driving bevel gear is separated from the first driven bevel gear.

[0020] By adopting the above technical solution, when the wind drives the blades to rotate, the mounting cylinder and the sliding cylinder will also rotate synchronously. When the sliding cylinder rotates, the engagement of the first active bevel gear and the first driven bevel gear will drive the generator to generate electricity. The electricity generated by the generator will be removed from the second battery to realize the collection of wind energy.

[0021] Optionally, the protection mechanism includes a placement plate placed on the ground, a support column fixed to the placement plate, a first protection curtain installed in the placement plate, two second protection curtains installed in the placement plate, and a protection drive component that simultaneously drives the first protection curtain and the second protection curtain to move to protect the solar energy collection mechanism and the wind collection mechanism, the two second protection curtains are located on opposite sides of the placement plate, and the first protection curtain is located at one end of the placement plate.

[0022] By adopting the above technical solution, the protection drive component can drive the first protection curtain and the second protection amount to cover the solar energy collection mechanism and the wind power collection mechanism, thereby protecting the solar energy collection mechanism and the wind power collection mechanism.

[0023] Optionally, the first and second reels are rotatably connected inside the opposite ends of the placement plate, one end of the first protective curtain is fixed to the first reel by a first coil spring, and the other end of the first protective curtain is wound around the second reel by a first pull rope, and the third and fourth reels are rotatably connected on both opposite sides of the placement plate, the third reel and the fourth reel are arranged in parallel, one end of the second protective curtain is fixed to the third reel by a second coil spring, and the other end of the second protective curtain is wound around the fourth reel by a second pull rope; the protection drive component includes a protection motor and a transmission gear fixed between the second reel and the fourth reel, the transmission gear includes a second active bevel gear fixed to the second reel and a second driven bevel gear slidably connected to the fourth reel, a fixed bevel gear capable of meshing with the second driven bevel gear is fixed to the ground, and a driving component for driving the second driven bevel gear to slide on the fourth reel to drive the second driven bevel gear to mesh with the second active bevel gear or to drive the second driven bevel gear to mesh with the fixed bevel gear is provided on the second reel and the fourth reel.

[0024] By adopting the above technical solution, it can be achieved that when the protection motor is started, the protection motor will drive the second reel and the fourth reel to rotate synchronously at the same time. When the second protection curtain is extended in place but the first protection curtain is not extended in place, the direction of the second driven bevel gear can be changed through the reversing member, so that the second reel and the fourth reel can rotate synchronously, or the protection motor can only drive the second reel to rotate, which makes the operation more flexible.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application, by setting up a solar energy collection mechanism and a wind power collection mechanism, can collect solar energy and wind power resources at sea to supply them to the seawater desalination system to meet the needs of the seawater desalination system. At the same time, the setting of the wind detection mechanism and the retraction mechanism enables the wind detection mechanism to detect the wind strength outside. When strong wind weather is detected outside, the retraction mechanism can be controlled to retract the wind power collection mechanism, thereby protecting the wind power collection mechanism; and when the outside encounters rainy and snowy weather, the protection mechanism can cover the solar energy collection mechanism and the wind power collection mechanism, thereby reducing the probability of the solar energy collection mechanism and the wind power collection mechanism being damaged by rainwater erosion; while solving the problem of insufficient energy at sea, it can also reduce the probability of damage to the solar panel; 2. The sliding fit between the fixing rod and the mounting tube enables the blades to be extended when in use, thereby collecting the wind at a high altitude. When the wind collection mechanism needs to be protected by a cover, the blades can also be lowered to reduce the overall floor space. 3. The second driven bevel gear adopts the setting of the composite gear, so that the meshing relationship of the second driven bevel gear can be changed by operating the sliding of the second driven bevel gear, thereby changing the driving force of the protective motor, and the operation is more flexible.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-14 This application is described in further detail.

[0042] The embodiment of the present application discloses a small-sized seawater desalination device, which includes a seawater desalination system, an energy collection system for providing energy to the seawater desalination system, and a storage system for storing seawater treated by the seawater desalination device.

[0043] Reference Figure 1 and Figure 2The energy collection system includes a solar energy collection mechanism 1 for collecting solar energy, an adjustment mechanism 2 for adjusting the installation angle of the solar energy collection mechanism 1, and a solar energy detection mechanism 31 for detecting the angle of the sun. The solar energy detection mechanism 31 is connected to the adjustment mechanism 2 through a controller. The solar energy detection mechanism 31 can detect the direction of the sun in real time and transmit the detected data to the controller in real time. The controller controls the action of the adjustment mechanism 2 according to the detected data, so that the solar energy collection mechanism 1 can always face the sun.

[0044] Specifically, the solar energy collection mechanism 1 includes a solar panel 11 for collecting solar energy and a first storage battery 12 connected to the solar panel 11 for storing the electricity collected by the solar panel 11 .

[0045] Reference Figure 2 and Figure 3 The adjustment mechanism 2 includes a U-shaped mounting plate 21 for mounting the solar panel 11, a first driving assembly 22 for driving the solar panel 11 to swing on the mounting plate 21, and a second driving assembly 23 for driving the solar panel 11 to rotate. The front of the solar panel 11 faces the sun for collecting solar energy, and the back is hinged to the opposite sides of the U-shaped mounting plate 21 through the connecting plate 13. The solar energy detection mechanism 3 is installed at the front of the solar panel 11.

[0046] The first driving assembly 22 includes a first electric push rod 221 hinged between the closed end of the mounting plate 21 and the connecting plate 13. One end of the first electric push rod 221 is hinged to the closed end of the mounting plate 21, and the other end is hinged to the end of the connecting plate 13 away from the solar panel 11. By controlling the first electric push rod 221 to extend or shorten, the connecting plate 13 can be driven to rotate around the hinge axis with the mounting plate 21, thereby adjusting the longitudinal installation angle of the solar panel 11.

[0047] The second driving assembly 23 includes a driving motor for driving the mounting plate 21 to rotate. The driving motor is placed vertically, and the output shaft of the driving motor is fixedly connected to the outer side of the closed end of the mounting plate 21, so that the mounting plate 21 and the solar panel 11 mounted on the mounting plate 21 can be driven to rotate, thereby adjusting the lateral installation angle of the solar panel 11.

[0048] Of course, a lifting assembly 24 can also be provided between the ground and the driving motor, and the lifting assembly 24 can be a cylinder or a scissor lift, so that the installation height of the solar panel 11 can be adjusted by the lifting assembly 24 to meet the needs of solar energy collection at different positions. This application takes the lifting assembly 24 as an example of using a scissor lift.

[0049] The solar energy detection mechanism 31 includes a solar sensor, which is an existing product and can detect the position of the sun relative to the solar sensor, thereby obtaining the position information of the sun.

[0050] Reference Figure 3 A linear displacement sensor 222 is also installed on the first electric push rod 221. The body of the linear displacement sensor 222 is fixedly connected to the body of the first electric push rod 221. The slide of the linear displacement sensor 222 is fixedly connected to the push rod of the first electric push rod 221, so that the telescopic length of the first electric push rod 221 can be detected in real time by the linear displacement sensor 222. The first electric push rod 221 and the linear displacement sensor 222 are both connected to the controller to control the extension or shortening of the first electric push rod 221 through the controller, and the linear displacement sensor 222 is for. At the same time, an encoder is installed on the output shaft of the drive motor. The encoder is used to collect the rotation amount of the output shaft of the drive motor in real time. The encoder and the drive motor are both connected to the controller to control the rotation amount of the output shaft of the drive motor through the controller.

[0051] Of course, the sun sensor is also connected to the controller. The sun sensor detects the real-time position of the sun relative to the sun sensor in real time, and transmits the detected data to the controller. It is understandable that the sun sensor transmits to the controller the horizontal and vertical azimuth angles of the sun relative to the sun sensor, thereby obtaining the angle data of the horizontal adjustment and the vertical adjustment of the solar panel. When the controller receives the data transmitted by the sun sensor, it will control the rotation of the drive motor according to the angle that the solar panel 11 needs to be adjusted horizontally. At this time, the encoder will detect the rotation angle of the rotating motor and transmit the detected data to the controller in real time. When the controller receives the data detected by the encoder reaching the set angle, the controller controls the drive motor to stop. At the same time, the controller will also control the first electric push rod 221 to extend or shorten according to the longitudinal angle that the solar panel 11 needs to adjust. At this time, the linear displacement sensor 222 will detect the value of the extension or shortening of the first electric push rod 221 and transmit the detected data to the controller. When the controller receives the data detected by the linear displacement sensor 222 reaching the set value, it will control the first electric push rod 221 to stop. At this time, the adjustment of the angle of the solar panel 11 is completed, so that the solar panel 11 is facing the sun. Of course, since the solar sensor will detect the position of the sun in real time and transmit the detected data to the controller in real time, the controller will also control the first electric push rod 221 and the drive motor to adjust the direction of the solar panel 11 in real time according to the data transmitted by the solar sensor, so that the solar panel 11 adjusts its angle as the sun moves and always faces the sun.

[0052] Reference Figure 2The energy collection system further includes a wind collection mechanism 4 for collecting wind power, a retracting mechanism 5 for controlling the extension or retraction of the wind collection mechanism 4, and a wind detection mechanism for detecting the strength of the wind. The wind detection mechanism and the retracting mechanism 5 are both connected to the controller to control the action of the retracting mechanism 5 according to the data detected by the wind detection mechanism, so as to control the wind collection mechanism 4 to extend to collect wind power, or to control the wind collection mechanism 4 to retract to protect the wind collection mechanism 4.

[0053] Reference Figure 4 and Figure 5 The wind collecting mechanism 4 includes a vertically placed mounting rod 41, a plurality of support rod groups 42 hinged on the outer wall of the mounting rod 41, and a blade 43 hinged on one end of each support rod group 42 away from the mounting rod 41. It can be understood that the shape of the blade 43 is consistent with the shape of the blade in the existing wind turbine, and it is necessary to realize the rotation around the axis of the mounting shaft 41 driven by the wind. The blade 43 in the drawings of the present application is only for illustration. Among them, a plurality of support rod groups 42 are arranged around the mounting rod 41 at intervals on the axis, and each support rod group 42 includes a first rod 421 hinged between the mounting rod 41 and the blade 43 and a second rod 422 hinged between the mounting rod 41 and the blade 43. The first rod 421 and the second rod 422 are arranged in parallel, so that a parallelogram-shaped connection structure is formed between the mounting rod 41, the first rod 421, the second rod 422, and the blade 43. The retracting mechanism 5 includes a sliding cylinder 51 slidably connected to the mounting rod 41, a retracting rod 52 hinged between the sliding cylinder 51 and the second rod 422, and a retracting assembly 53 for driving the sliding cylinder 51 to slide on the mounting rod 41. A triangular support structure is formed between the retracting rod 52, the second rod 422 and the mounting rod 41. Under normal conditions, the second rod 422 is supported by the retracting rod 52 to ensure the installation stability of the blade 43. When the outside world encounters severe weather such as typhoons, the retracting assembly 53 can drive the sliding cylinder 51 to slide on the mounting rod 41, so that the retracting rod 52 drives the second rod 422 to rotate around the hinge axis with the mounting rod 41 until the blade 43 fits on the mounting rod 41, thereby realizing the folding of the blade 43.

[0054] The mounting rod 41 includes a fixed rod 411 fixed on the ground and a mounting tube 412 slidably connected to the fixed rod 411, and the sliding tube 51 is slidably sleeved on the mounting tube 412. The contraction assembly 53 includes a driving ring 531 rotatably connected to the sliding tube 51 and a second electric push rod 532 fixed between the driving ring 531 and the ground. At the same time, a first fixing ring 44 is fixed to the mounting tube 412 to limit the sliding tube 51 from sliding down to the limit position, and a second fixing ring 45 is fixed to the mounting tube 412 to limit the sliding tube 51 from sliding up to the limit position. When the second electric push rod 532 drives the sliding tube 51 to slide downward on the mounting tube 412 through the driving ring 531, the contraction rod 52 will also drive the blades 43 to close until the blades 43 close, and at this time, the sliding tube 51 also abuts against the first fixing ring 44. As the second electric push rod 532 drives the sliding cylinder 51 to continue to slide down, the sliding cylinder 51 will also drive the mounting cylinder 412 to slide on the fixing rod 411 through the first fixing ring 44, thereby causing the entire wind collection mechanism 4 to shrink.

[0055] The wind detection mechanism may be an anemometer, which may be mounted on the mounting rod 41 or any other suitable position, as long as the wind speed can be detected. The anemometer is connected to the second electric push rod 532 through a controller. When the anemometer detects that the external wind is strong and strong wind weather occurs, the controller controls the second electric push rod 532 to retract, thereby retracting the blades 43 to protect the blades 43 and reduce the probability of damage to the wind collection mechanism 4 caused by strong wind weather.

[0056] Reference Figure 2 The wind collecting mechanism 4 also includes a generator 46 connected to the sliding cylinder 51 and a second battery 47 connected to the generator 46 for storing the electricity generated by the generator 46. A first active bevel gear 461 is fixedly connected to the sliding cylinder 51, and a first driven bevel gear 462 is fixedly connected to the input shaft of the generator 46. When the blades 43 are rotated by the wind, the blades 43 also drive the sliding cylinder 51 to rotate. At this time, the first active bevel gear 461 and the first driven bevel gear 462 are engaged to drive the generator 46 to generate electricity, and the electricity generated by the generator 46 will be stored in the second battery 47.

[0057] Reference Figure 5 At the same time, a block 451 is fixedly connected to the side of the second fixing ring 45 facing the sliding cylinder 51, and a plurality of blocks 451 are arranged at intervals around the axis of the sliding cylinder 51. At the same time, a slot 511 for the block 451 to be embedded is opened on the end wall of the sliding cylinder 51. Through the cooperation between the block 451 and the slot 511, the sliding cylinder 51 can be driven by the blade 43 to rotate synchronously with the mounting cylinder 412.

[0058] Reference Figure 1 and Figure 6 The energy collection system also includes a protective mechanism 6 for protecting the solar energy collection mechanism 1 and the wind power collection mechanism 4. The protective mechanism 6 is used to automatically cover the solar energy collection mechanism 1 and the wind power collection mechanism 4 when rain and snow occur in the outside world, so as to protect the solar energy collection mechanism 1 and the wind power collection mechanism 4. At the same time, a rain and snow transmitter 32 is also provided for detecting whether rain and snow occur in the outside world. The rain and snow transmitter 32 can detect whether rain and snow occur in the outside world. The rain and snow transmitter 32 is connected to the protective mechanism 6 through a controller. When the rain and snow transmitter 32 detects that rain and snow occur in the outside world, the protective mechanism 6 will automatically start to cover the solar energy collection mechanism 1 and the wind power collection mechanism 4 to protect the solar energy collection mechanism 1 and the wind power collection mechanism 4.

[0059] The protection mechanism 6 includes a placement plate 61, four support columns 62 fixedly connected to the placement plate 61, and a support frame 63 fixedly connected to one end of the four support columns 62 away from the placement plate 61. The placement plate 61, the four support columns 62 and the support frame 63 together surround and form a protection space 64. The solar energy collection mechanism 1 and the wind power collection mechanism 4 are both installed in the protection space 64, and the rain and snow transmitter 32 can be placed on the support frame 63. A first protection curtain 65, two second protection curtains 66, and a protection drive assembly 67 (refer to FIG. 1 ) for simultaneously driving the first protection curtain 65 and the second protection curtain 66 to cover the solar energy collection mechanism 1 and the wind power collection mechanism 4 through the first protection curtain 65 and the second protection curtain 66 are also installed inside the placement plate 61. Fig.12 ).

[0060] Reference Figure 7 and Figure 8 , the first protective curtain 65 is located at one end of the placement plate 61, and the two second protective curtains 66 are located on opposite sides of the placement plate 61 and are respectively located at the two ends of the first protective curtain 65. When in use, the free end of the first protective curtain 65 can be pulled from one end of the placement plate 61 to one end of the support frame 63 through the protection drive assembly 67, and then along the support frame 63 to the other end of the support frame 63, and finally to the other end of the placement plate 61, thereby covering the two ends and the upper part of the protection space 64. The protection drive assembly 67 also simultaneously pulls the free ends of the two second protective curtains 66 to the support frame 63, thereby covering the two sides of the protection space 64, and achieving sealing of the protection space 64.

[0061] Reference Figure 8 and Fig. 9Specifically, a first reel 681 and a second reel 682 are rotatably connected inside the opposite ends of the placement plate 61, a first coil spring 683 is fixedly connected to the first reel 681, one end of the first protective curtain 65 is fixedly connected to the first coil spring 683, and the other end is wound around the first coil spring 683 and then extends out of the placement plate 61, and a first pull rope 684 is fixedly connected to the free end of the first protective curtain 65, one end of the first pull rope 684 is fixedly connected to the first protective curtain 65, and the other end of the first pull rope 684 is fixedly connected to the second reel 682 after passing through the support column 62 and the support frame 63. At the same time, a first accommodating groove 685 for the first pull rope 684 to be inserted and slide is opened on the side of the support column 62 and the support frame 63 facing the first protective curtain 65. Among them, there are two first pull ropes 684, and the two first pull ropes 684 are respectively located on both sides of the first protective curtain 65. Two first accommodating grooves 685 are also opened accordingly. The openings of the two first accommodating grooves 685 are arranged opposite to each other, so that after the first protective curtain 65 is pulled by the first pull rope 684 to cover the protective space 64, the two sides of the first protective curtain 65 are also located in the two first accommodating grooves 685, so that the folding of the protective space 64 is tighter.

[0062] At the same time, in order to determine whether the first protective curtain 65 has completely covered the protective space 64, a first limiting plate 686 is fixed to one end of the first protective curtain 65 to which the first pull rope 684 is fixed. The first limiting plate 686 is located on one side of the first protective curtain 65, and first travel switches 687 are fixed on both opposite sides of the first limiting plate 686, so that under normal circumstances, the first travel switch 687 on one side of the first limiting plate 686 abuts against the placement plate 61, thereby fixing the initial position of the first protective curtain 65. When the first pull rope 684 drives the first protective curtain 65 to cover the protective space 64, the first protective curtain 65 will be pulled upward to the support frame 63 first, and then move to the other end of the placement plate 61. When it reaches the other end of the placement plate 61, it will move downward until it reaches the placement plate 61, thereby covering the protective space 64. When the free end of the first protective curtain 65 reaches the placement plate 61, the first travel switch 687 on the first limit plate 686 will abut against the placement plate 61, thereby indicating the state of the first protective curtain 65. At this time, stop pulling the first pull rope 684.

[0063] Reference Figure 6 and Fig.10 The second protective curtains 66 are located on two opposite sides of the protective space 64, and the structures of the second protective curtains 66 located on two opposite sides of the protective space 64 are the same. This application takes the structure of one of the second protective curtains 66 as an example for description.

[0064] Reference Figure 7 , Fig.10 and Fig.11A third reel 691 is fixedly connected to the inside of the placing plate 61 and a fourth reel 692 is rotatably connected thereto. The third reel 691 and the fourth reel 692 are located on the same side of the placing plate 61. A second coil spring 693 is fixedly connected to the third reel 691. One end of the second protective curtain 66 is fixedly connected to the second coil spring 693. The other end of the second protective curtain 66 is fixedly connected to a second pull rope 694. One end of the second pull rope 694 away from the second protective curtain 66 is fixedly connected to the fourth reel 692. At the same time, a second receiving groove 695 for the second pull rope 694 to be inserted is provided on the support column 62 at both ends of the second protective curtain 66, and a third receiving groove 696 for the second protective curtain 66 to be inserted is provided on the portion of the support frame 63 located just above the second protective curtain 66. Both ends of the third receiving groove 696 are connected to the second receiving groove 695, and a reversing roller 697 is rotatably connected in the third receiving groove 696, and the middle part of the second pull rope 694 is wound around the reversing roller 697. When the fourth reel 692 is operated to rotate, the third reel 691 will drive the second pull rope 694 to be wound around the fourth reel 692, and the second pull rope 694 will also drive the second protective curtain 66 to be released from the third reel 691, and drive the second coil spring 693 to be wound, until the second protective curtain 66 reaches the third receiving groove 696, so as to realize the protection of one side of the protection space 64.

[0065] At the same time, in order to automatically monitor the state of the second protective curtain 66, a second limit plate 698 is fixedly connected to the free end of the second protective curtain 66. The second limit plate 698 is located on one side of the second protective curtain 66, and second travel switches 699 are fixedly connected to the opposite sides of the second limit plate 698. Under normal conditions, the second travel switch 699 on one side of the second limit plate 698 abuts against the placement plate 61, thereby fixing the initial state of the second protective curtain 66. When the second pull rope 694 pulls the free end of the second protective curtain 66 to the third accommodating groove 696, the second travel switch 699 on the other side of the second limit plate 698 abuts against the support frame 63, thereby indicating that the second protective curtain 66 is in place, and at this time, the fourth reel 692 can be directly stopped from rotating.

[0066] Reference Fig.12 and Fig.13The protection drive assembly 67 includes a protection motor 671 fixedly connected to the end of the second reel 682 and a transmission gear 672 connected between the second reel 682 and the fourth reel 692, wherein the transmission gear 672 includes a second active bevel gear 6721 fixedly connected to the second reel 682 and a second driven bevel gear 6722 slidably connected to the fourth reel 692, and a fixed bevel gear 673 capable of meshing with the second driven bevel gear 6722 is also fixedly connected inside the placement plate 61, and the fixed bevel gear 673 is located on the side of the second driven bevel gear 6722 away from the second active bevel gear 6721. Under normal conditions, the second driven bevel gear 6722 is meshed with the second active bevel gear 6721. When the protection motor 671 is started, the protection motor 671 will simultaneously drive the second reel 682 and the fourth reel 692 to rotate through the transmission gear 672, thereby winding the first pull rope 684 around the second reel 682 and the second pull rope 694 around the fourth reel 692. When the free end of the second protection curtain 66 reaches the third accommodating groove 696, the second travel switch 699 also abuts against the support frame 63. At this time, the second driven bevel gear 6722 is operated to move on the fourth reel 692, so that the second driven bevel gear 6722 is disengaged from the second active bevel gear 6721 and meshed with the fixed bevel gear 673. At this time, the position of the second driven bevel gear 6722 can be fixed by the fixed bevel gear 673. The protection motor 671 will continue to drive the second reel 682 to rotate until the first travel switch 687 abuts against the placement plate 61 and the protection motor 671 stops.

[0067] The second driven bevel gear 6722 is a composite body formed by fixing two bevel gears on one side away from the teeth, so that the second driven bevel gear 6722 has teeth on both sides, that is, it can mesh with the second active bevel gear 6721 on one side and the fixed bevel gear 673 on the other side.

[0068] Reference Fig.14 In order to enhance the ability of the first protective curtain 65 and the second protective curtain 66 to resist external forces, the first protective curtain 65 and the second protective curtain 66 both adopt a composite layer structure. This application takes the specific structure of the first protective curtain 65 as an example for explanation.

[0069] The first protective curtain 65 includes a first waterproof cloth 651, a second waterproof cloth 652 fixedly connected to one side of the first waterproof cloth 651, and a reinforcing rib 653 fixedly connected between the first waterproof cloth 651 and the second waterproof cloth 652. A plurality of reinforcing ribs 653 are arranged at intervals along the length direction of the first waterproof cloth 651. The width of the reinforcing rib 653 is consistent with the width of the first protective curtain 65, so that the first protective curtain 65 can be bent while increasing the ability of the first protective curtain 65 to resist external forces, thereby preventing the first protective curtain 65 from slipping out of the first accommodating groove 685 under the influence of external rain or snow, resulting in poor protection.

[0070] Reference Fig.13 , a driving assembly 674 is also provided on the fourth reel 692 to drive the second driven bevel gear 6722 to slide on the fourth reel 692, and the driving assembly 674 includes a first electromagnet 6741 fixedly connected to the fourth reel 692 and a second electromagnet 6742 fixedly connected to the fourth reel 692, the first electromagnet 6741 and the second electromagnet 6742 are respectively located on both sides of the second driven bevel gear 6722, and the present application takes the first electromagnet 6741 close to the second active bevel gear 6721 as an example for explanation. When the first electromagnet 6741 is energized, the second driven bevel gear 6722 can be adsorbed to mesh with the second active bevel gear 6721; when the second electromagnet 6742 is energized, the second driven bevel gear 6722 can be adsorbed to mesh with the fixed bevel gear 673.

[0071] Reference Figure 1 The seawater desalination system includes a seawater pretreatment mechanism 71 , a reverse osmosis membrane treatment mechanism 72 connected to a water outlet of the seawater pretreatment mechanism 71 , and a mineralization mechanism 73 connected to a water outlet of the reverse osmosis membrane treatment mechanism 72 .

[0072] One end of the seawater pretreatment mechanism 71 extends into the sea through a pipeline to pump up seawater, and it includes a multi-stage filter screen and an ultrafiltration membrane processing unit arranged inside, wherein the ultrafiltration membrane processing unit includes an organic membrane and an inorganic ceramic membrane, which is mainly used to filter large particle impurities in seawater.

[0073] The reverse osmosis membrane treatment mechanism 72 is used to receive the water treated by the seawater pretreatment mechanism 71 and filter out the salt and the like in the seawater.

[0074] The mineralization mechanism 73 is used to receive the water treated by the reverse osmosis membrane treatment mechanism 72 and add minerals to the filtered water to ensure that the mineralized substances in the treated water can meet the needs of the human body.

[0075] The desalination system is connected to the first battery 12 and the second battery 47 through electric wires, so that the electricity stored in the first battery 12 and the second battery 47 provides energy for the operation of the desalination system. The specific structure of the desalination system and the method of treating water are prior art, and will not be repeated in this application.

[0076] Of course, a third battery is also provided, which is connected to the diesel generator on board to generate electricity and store electricity through the diesel generator on board. When the electricity stored in the first battery 12 and the second battery 47 is insufficient, the third battery can be used to power the desalination system, and when the power in the third battery is less than the set value, the diesel generator will generate electricity again and store the electricity in the third battery, ensuring that there is always sufficient electricity in the third battery. The third battery can be used as a backup battery for the desalination system to ensure the normal operation of the desalination system.

[0077] Of course, the first battery 12 and the second battery 47 can also be connected to electrical equipment on the ship, so that when the first battery 12 and the second battery 47 store a lot of electricity, the excess electricity will be supplied to the remaining electrical equipment on the ship to ensure full utilization of electricity.

[0078] Reference Figure 1 The fresh water storage system 8 includes a water tank connected to the water outlet of the mineralization mechanism 73, and the water desalinated by the seawater desalination system is stored in the water tank. A liquid level detector is provided in the water tank, and the liquid level detector is used to detect the liquid level in the water tank in real time. The liquid level detector is connected to the seawater desalination system through a controller. When the liquid level detector detects that the water in the water tank is lower than the set value, the controller will control the seawater desalination system to start desalinating the seawater. When the liquid level detector detects that the water level in the water tank is higher than the set value, the seawater desalination system will stop working, which can save energy while ensuring the supply of fresh water.

[0079] The implementation principle of a small seawater desalination device in the embodiment of the present application is as follows: under normal conditions, the solar panel 11 always faces the sun to collect solar energy, and the blades 43 drive the installation cylinder 412 to rotate under the action of wind force, and the installation cylinder 412 will also drive the sliding cylinder 51 to rotate through the cooperation of the block 451 and the slot 511, and the sliding cylinder 51 will drive the input shaft of the generator 46 to rotate through the first active bevel gear 461 and the first driven bevel gear 462 to achieve power generation. When the anemometer detects that the external wind force is greater than the set value, the second electric push rod 532 shrinks, thereby driving the sliding cylinder 51 to slide on the installation cylinder 412, so that the blades 43 gather on the installation cylinder 412. As the sliding cylinder 51 continues to slide, the sliding cylinder 51 will abut against the second fixing ring 45 and drive the installation cylinder 412 to slide until the installation cylinder 412 slides to the lowest position, and the wind collection mechanism 4 can be folded, reducing the probability of the blades 43 being damaged by the strong wind from the outside. When the rain and snow transmitter detects that the outside world is encountering rain and snow, it will control the wind collecting mechanism 4 to fold and the lifting assembly 24 to shrink, so that the solar energy collecting mechanism 1 and the wind collecting mechanism 4 reduce their footprint, and then control the protection motor 671 to start, so that the first protection curtain 65 and the second protection curtain 66 jointly cover the solar energy collecting mechanism 1 and the wind collecting mechanism 4, to achieve waterproof protection for the solar energy collecting mechanism 1 and the wind collecting mechanism 4, and reduce the probability of the solar energy collecting mechanism 1 and the wind collecting mechanism 4 being damaged by rain and snow.

[0080] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
