It can be used for cooling water, flushing water, drinking water, etc. depending on the degree of purification. However, traditional marine seawater purification equipment consumes onboard energy, resulting in increased energy consumption. Therefore, marine seawater purification equipment driven by wind energy has emerged, which can effectively solve the energy consumption problem.

[0027] 5. The present invention configures the energy storage unit to consist of a plurality of battery cells, cleverly utilizes the circuit connection relationship to connect the battery cells in series, and connects a plurality of mechanical switches in parallel, thereby achieving torque regulation of the motor that is completely adaptively regulated by the wind force, without the need for manual or algorithmic control.

DETAILED DESCRIPTION

[0038] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Example 1:

[0041] A wind-powered seawater filtration and purification device for ships, such as Figure 1-9 As shown, it includes a frame 1 fixed on the hull, a purification unit 3 arranged on the inner side of the frame 1 and a pump head 5 fixed to the inner wall of the frame 1 by bolts, and a wind energy drive unit 4 is provided on the top side wall of the frame 1. The wind energy drive unit 4 is transmission-connected to the input shaft of the pump head 5, and the water outlet of the pump head 5 is connected to the water inlet of the purification unit 3 through a pipeline, and the water inlet of the pump head 5 is connected to a counterweight ball head 7 through a hose 6.

[0042] The purification section 3 includes a filter box 8 and a water tank 13. A partition 9 is welded to the inner wall of the filter box 8, and the partition 9 divides the inner cavity of the filter box 8 into two parts. One part of the inner cavity of the filter box 8 is provided with a filter 10, and the other part of the inner cavity of the filter box 8 is provided with a connecting pipe 11 and an electric heating plate 12. The connecting pipe 11 is clamped to the inner wall of the partition 9, and a plurality of atomizing nozzles 15 are fixed to the outer wall of the connecting pipe 11 by bolts. The top of the filter box 8 is connected to the water tank 13 through a condenser pipe 14.

[0043] The inner wall of the filter box 8 is slidably connected to a scraper 16 through a guide rod. The scraper 16 contacts and cooperates with the surface of the electric heating plate 12, and a group of driving parts 20 for driving the position of the scraper 16 are respectively provided on the inner and outer sides of the filter box 8.

[0044] The driving member 20 includes a cylinder 17 , a piston 18 and a connecting rod 19 . The piston 18 is slidably connected to the inner wall of the cylinder 17 , and the side wall of the piston 18 is connected to the side wall of the scraper 16 through the connecting rod 19 .

[0045] When the device is in use, the wind energy drive unit 4 can drive the pump head 5 to move, thereby sucking in seawater through the hose 6 and transporting it to the filter box 8. First, the seawater is filtered through the filter 10, and then transported to the multiple atomizing nozzles 15 through the connecting pipe 11 for atomization and spraying onto the surface of the electric heating plate 12. After high-temperature evaporation on the electric heating plate 12, it enters the condenser 14 for condensation. After condensation, the clean water enters the water tank 13 for storage. In addition, when in use, since the temperature of the inner cavity of the filter box 8 is high and the temperature outside the filter box 8 is relatively low, the gas pressure in the inner cavity of the outer cylinder 17 is low, and the gas pressure in the inner cavity of the inner cylinder 17 is high, so that the scraper 16 is pushed to one side of the electric heating plate 12 by the air pressure. After a single use, the temperature of the inner cavity of the filter box 8 gradually decreases, causing the scraper 16 to move to the other side of the electric heating plate 12, scraping off the dirt on the surface of the electric heating plate 12 while moving.

[0046] This device purifies seawater by filtering first, evaporating, and then condensing, thereby increasing the purification effect. A scraper 16 is provided to scrape the surface of the electric heating plate 12, thereby preventing the decrease in heat conductivity caused by the accumulation of dirt and increasing the evaporation effect. The scraping power of the scraper 16 is achieved by the gas pressure difference caused by the temperature difference between the inside and outside of the filter box 8, thereby reducing the power source layout.

[0047] In order to solve the problem of wind energy drive; Figure 4 As shown, the wind energy drive unit 4 includes a turbine blade 21, a main shaft 22 and a bevel gear 24 rotatably connected to the inside of the frame 1. The main shaft 22 and the bevel gear 24 can be axially slidably matched, which can be specifically achieved through the clearance fit between the key and the keyway. This is common knowledge for those skilled in the art, so it is not described in detail in this embodiment. The turbine blade 21 is fixedly connected to the end of the main shaft 22, and the bottom of the bevel gear 24 is engaged with a bevel gear 26, which is connected to the input shaft of the pump head 5 through a key.

[0048] When there is sea breeze, it acts on the surface of the turbine blade 21, thereby driving the turbine blade 21 to rotate, thereby driving the bevel gear 1 24 to rotate, and then driving the bevel gear 2 26 to rotate, and then driving the pump head 5 to operate.

[0049] Since the structure of the purification unit 3 is fixed, the maximum or optimal water flow rate is certain during purification. When the water flow rate is fast, the purification unit 3 will be overloaded, reducing the purification effect. When the water flow rate is slow, load redundancy will occur, causing the seawater purification rate to decrease, resulting in resource waste. In order to solve the problem of constant water flow rate; Figure 4-8 As shown, the wind energy driving unit 4 further includes a speed increasing unit 23 and a speed reducing unit 25 .

[0050] The speed increasing part 23 includes a gear ring 27 fixed to the outer wall of the main shaft 22 and a motor 29 fixed to the side wall of the frame 1 by bolts. The outer wall of the output shaft of the motor 29 is fixed with a gear 30 that can mesh with the gear ring 27. The gear ring 27 and the opposite side of the bevel gear 24 are buckled with the same spring 28.

[0051] The deceleration unit 25 includes an outer shell 31 fixed to the side wall of the frame 1 by bolts, a winding stator 32 embedded and fixed to the inner wall of the outer shell 31, and a rotor core 33 fixed to the outer wall of the end of the main shaft 22.

[0052] An energy storage unit 2 is provided at the bottom of the frame 1 , and the power output end of the winding stator 32 is electrically connected to the charging end of the energy storage unit 2 .

[0053] When the wind force is moderate, the force acting on the surface of the turbine blade 21 is also moderate. At this time, the spring 1 28 is compressed to a certain extent, so that the gear ring 27 is separated from the gear 30, and the winding stator 32 is separated from the rotor core 33. At this time, the turbine blade 21 is driven to rotate by the wind, thereby providing driving force for the pump head 5. When the wind force is strong, the force acting on the surface of the turbine blade 21 increases, so that the main shaft 22 moves backward as a whole, and the rotor core 33 is inserted into the interior of the winding stator 32. The relative movement between the winding stator 32 and the rotor core 33 is the main force. The rotation of the shaft 22 provides resistance, thereby balancing the rotation speed of the main shaft 22, and while providing resistance, the winding stator 32 can convert mechanical energy into electrical energy and store it in the energy storage unit 2; when the wind force is relatively small, the force of the wind acting on the surface of the turbine blades 21 is reduced, so that the main shaft 22 is moved forward by the elastic force of the spring 28 until the gear 30 is engaged with the gear ring 27, and the motor 29 is started to assist in providing torque for the rotation of the main shaft 22, ensuring the uniformity of its rotation speed, and the torque provided by the motor 29 can be controlled by the input function of the motor 29.

[0054] The winding stator 32 is composed of a plurality of winding units arranged in a linear array.

[0055] When the wind force is stronger, the rotor core 33 is equipped with more winding units, thereby providing more resistance and converting more electricity.

[0056] This device is provided with a speed-increasing part 23, which can achieve the engagement of the gear ring 27 and the gear 30 through the displacement of the main shaft 22 when the wind force is small and the speed of the main shaft 22 is reduced, so that the motor 29 provides torque to the main shaft 22, thereby ensuring that the speed of the main shaft 22 is relatively constant, thereby ensuring that the input power of the pump head 5 is relatively constant, and ensuring the working effect and efficiency of the purification part 3.

[0057] In addition, the present device is provided with a deceleration part 25, which can realize damping deceleration by utilizing the cooperation between the rotor core 33 and the winding stator 32 when the wind force is strong, thereby ensuring that the rotation speed of the main shaft 22 is relatively constant, thereby ensuring that the input power of the pump head 5 is relatively constant, ensuring the working effect and efficiency of the purification part 3, and can convert the damping energy of the deceleration into electrical energy and store it in the energy storage unit 2 to achieve energy saving effect, and the winding stator 32 is composed of a plurality of winding units arranged in a linear array, which can also adaptively adjust the damping size according to the amplitude of the increase in wind speed.

[0058] In this embodiment, when there is sea breeze, it acts on the surface of the turbine blades 21, thereby driving the turbine blades 21 to rotate, thereby driving the bevel gear 1 24 to rotate, and then driving the bevel gear 2 26 to rotate, and then driving the pump head 5 to operate, thereby sucking seawater through the hose 6 and transporting it to the filter box 8. First, the seawater is filtered through the filter 10, and then transported through the connecting pipe 11 to the multiple atomizing nozzles 15 for atomization and spraying onto the surface of the electric heating plate 12. After evaporation at high temperature in the electric heating plate 12, it enters the condenser 14 for condensation. After condensation, the clean water enters the water tank 13 Storage, and, in the use state, since the temperature of the cavity of the filter box 8 is high, and the temperature outside the filter box 8 is relatively low, the gas pressure in the cavity of the outer cylinder 17 is small, and the gas pressure in the cavity of the inner cylinder 17 is large, thereby pushing the scraper 16 to one side of the electric heating plate 12 through the action of air pressure. After a single use is completed, the temperature of the cavity of the filter box 8 gradually decreases, thereby causing the scraper 16 to move to the other side of the electric heating plate 12, scraping off the dirt on the surface of the electric heating plate 12 while moving, and when the wind force is moderate, it acts on the turbine blades The force on the surface of the blade 21 is also moderate. At this time, the spring 1 28 is compressed to a certain extent, so that the gear ring 27 is separated from the gear 30, and the winding stator 32 is separated from the rotor core 33. At this time, the wind force drives the turbine blade 21 to rotate, thereby providing driving force for the pump head 5. When the wind force is strong, the force acting on the surface of the turbine blade 21 increases, causing the main shaft 22 to move backward as a whole. The rotor core 33 is inserted into the interior of the winding stator 32. The relative movement of the winding stator 32 and the rotor core 33 provides resistance to the rotation of the main shaft 22, thereby balancing. The rotation speed of the main shaft 22 is increased, and at the same time as providing resistance, the winding stator 32 can convert mechanical energy into electrical energy and store it in the energy storage unit 2; when the wind force is relatively small, the force of the wind acting on the surface of the turbine blades 21 is reduced, so that the main shaft 22 is moved forward by the elastic force of the spring 28 until the gear 30 is engaged with the gear ring 27. The motor 29 is started to assist in providing torque for the rotation of the main shaft 22 to ensure the uniformity of its rotation speed, and the torque provided by the motor 29 can be controlled by the input function of the motor 29, thereby controlling the input power of the pump head 5.

[0059] Example 2:

[0060] A wind-powered seawater filtration and purification device for ships, such as Figure 1-9 As shown, in order to solve the problem of adaptively adjusting the torque supply size according to the reduction amplitude of wind force when the wind force decreases, this embodiment makes the following improvements on the basis of embodiment 1: a connecting ring 41 is welded to the front side of the gear ring 27, and a double cone head 43 is provided on the outer wall of the connecting ring 41. The maximum outer diameter of the double cone head 43 is smaller than the diameter of the gear ring 27, and a support plate 40 is fixed to the outer wall of one side of the frame 1 by bolts, and a plurality of groups of mechanical switches 35 are provided on the inner wall of the support plate 40.

[0061] The mechanical switch 35 includes a slide rod 39 longitudinally connected to the support plate 40 and a spring 36 sleeved on the outer wall of the slide rod 39. A conductive sheet 38 is bonded to the bottom outer wall of the slide rod 39. Two independent electrode columns 37 are fixedly embedded on the outer wall of the support plate 40 located at the bottom of the conductive sheet 38, and a ball 34 is rolled on the top of the conductive sheet 38.

[0062] The energy storage unit 2 is composed of a plurality of battery cells 42 , and the number of the battery cells 42 is the same as the number of the mechanical switches 35 .

[0063] The battery cells 42 are connected in series with each other, one end of one of the battery cells 42 is electrically connected to one of the power terminals of the motor 29, multiple groups of mechanical switches 35 are connected in parallel to the other terminal of the motor 29, and the other ends of the multiple mechanical switches 35 are connected one-to-one to the discharge terminals of the multiple battery cells 42.

[0064] During use of this embodiment, when the wind force decreases and the gear ring 27 moves forward, the connecting ring 41 moves forward accordingly until the gear 30 engages with the gear ring 27. At this time, the ball 34 closest to the double-cone head 43 cooperates with the double-cone head 43 and moves downward due to the limit of the double-cone head 43, thereby causing the electrode column 37 to contact the conductive sheet 38. The two electrode columns 37 are connected through the conductive sheet 38, and the set of mechanical switches 35 is closed. At this time, one of the battery cells 42 supplies power to the motor 29. When the wind force continues to decrease, the double-cone head 43 will continue to move forward, thereby contacting the next set of mechanical switches 35, causing the next set of mechanical switches 35 to close. The previous set of mechanical switches 35 is disconnected by the elastic force of the second spring 36. At this time, two of the battery cells 42 are connected in series to supply power to the motor 29, increasing its input power and output torque. This cycle continues. Every time the wind force decreases by a certain amount, an additional battery cell 42 will be added to the power supply of the motor 29, increasing its torque output, thereby ensuring a relatively constant speed of the main shaft 22.

[0065] This device, by providing a connecting ring 41, a double-cone head 43 and multiple sets of mechanical switches 35, can control the mechanical switch 35 specifically coordinated with the double-cone head 43 according to the extent of wind force reduction, thereby achieving control of the output torque of the motor 29 according to the size of the wind force, thereby ensuring that the speed of the main shaft 22 is relatively constant.

[0066] In addition, the present device configures the energy storage unit 2 to consist of a plurality of battery units 42, and then cleverly utilizes the circuit connection relationship to connect the battery units 42 in series, and connects a plurality of sets of mechanical switches 35 in parallel, thereby enabling the torque regulation of the motor 29 to be completely adaptively adjusted by the wind force, without the need for manual and algorithmic control, and having high convenience and a fast response speed.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
