The central axis of the through hole on the swing plate 42 is perpendicular to the adjacent filter elements 45, so as to make the filter elements 45 evenly contact with the sea air.

A filter sponge located between the adjacent filter screens 191 and the adjacent electric blinds 13 is fixedly connected in the air inlet duct 11, and a second driving element 46 is arranged on the rear side of the air guide 12. The driving shaft of the second driving element 46 is fixedly connected with a first gear 47, and the two first racks 40 are meshed with the first gear 47. An auxiliary cleaning component is arranged in the air guide 12 to assist in processing all the filter elements 45.

[0023] like Figure 7-10As shown, the auxiliary cleaning component includes a baffle plate 50 with the same number as the swing plate 42, the baffle plate 50 is slidably connected to the adjacent swing plate 42, the baffle plate 50 and the adjacent swing plate 42 are limited and matched, a spring is arranged between the baffle plate 50 and the adjacent swing plate 42, the spring is used to drive the adjacent baffle plate 50 to reset and move, the baffle plate 50 is provided with through holes distributed in a rectangular array, the through holes on the baffle plate 50 are connected and matched with the adjacent through holes on the adjacent swing plate 42, when the through holes on the baffle plate 50 are connected with the adjacent through holes on the adjacent swing plate 42, the sea air can enter the air inlet duct 11 through the through holes of the baffle plate 50 and the adjacent swing plate 42, the connecting seat 43 is provided with a V-shaped liquid guide groove, when the upper sides of the two adjacent swing plates 42 swing toward each other, the two adjacent filter elements 45 are squeezed After the filter element 45 is squeezed, the moisture absorbed in it flows into the V-shaped liquid guide groove in the adjacent connecting seat 43.

A connecting rope connecting the rotating shell 54 and the adjacent baffle plate 50 is fixedly connected between the two.

[0024] When it is necessary to use this device to provide fresh air to the cabin, the staff installs this device on the LNG transport ship. When it is necessary to provide fresh air to the cabin, the staff controls the electric shutter 13 on the air inlet duct 11 through the control terminal to block the left side of the air inlet duct 11, so that the sea air will not enter it from the left side of the air inlet duct 11. Then the staff controls the exhaust member 14 of the control terminal, and the exhaust member 14 draws sea air, so that the sea air enters the air inlet duct 11 from the lower side of the air guide member 12 and is transported to the subsequent processing equipment (not shown in the figure) from the right side. The purpose of adopting the lower side air intake in the present invention is: extracting sea air from below can prevent water droplets and salt mist splashed by waves from directly entering the air inlet duct 11 with the sea breeze.

[0025] When the sea air enters the air guide 12, it passes through the adjacent filter 191, and the filter 191 filters the impurities and plankton in the sea air, so that the sea air passing through the lower part of the air guide 12 is in a clean state. The sea air filtered by the filter 191 then contacts the lower side of all the baffles 50.

[0026] When the sea air contacts all the baffles 50, taking one of the baffles 50 as an example, the sea air contacting the baffle 50 then enters the through holes distributed in the rectangular array thereon, and under the action of the through holes on the baffle 50 being connected with the adjacent through holes on the adjacent swing plate 42, the sea air flows through the through holes on the baffle 50 and the swing plate 42, and the sea air contacts the adjacent filter element 45 after passing through the through holes on the swing plate 42, and the filter element 45 filters and absorbs the moisture in the sea air (because the central air conditioning fresh air system is installed on the ship, the ship sails on the sea and is surrounded by moisture. When the sea surface is evaporated, a large amount of water vapor will be emitted to the surroundings, which will cause the air humidity on the sea surface to be higher), so that the sea air passing through the middle part of the air guide 12 is in a dry state, thereby reducing the burden of subsequent moisture treatment.

[0027] The purified sea air enters the air inlet duct 11 through the upper part of the air guide 12, thereby realizing the transmission of sea air. During the transmission of sea air, the air volume detection module in the air inlet duct 11 monitors the air volume of sea air flowing through the air inlet duct 11 in real time.

[0028] In the process of treating the sea air, the sea air is filtered and purified when it flows through the filter 191 located on the lower side. Under the action of the central axis of the through hole on the swing plate 42 being perpendicular to the adjacent filter element 45, the sea air is evenly contacted with the filter element 45. Under the action of several swing plates 42 being combined into a folded shape, the treatment area of ​​the sea air is increased.

[0029] When the wind volume of sea air flowing through the air inlet duct 11 is reduced, the wind volume detection module in the air inlet duct 11 transmits an electrical signal to the control terminal, and the control terminal controls the electric shutter 13 on the lower side to block the upper side of the air guide 12, so that the air guide 12 is not connected to the air inlet duct 11, and then the control terminal controls the electric shutter 13 on the upper side to remove the obstruction on the left side of the air inlet duct 11, so that the sea air enters the air inlet duct 11 from the left side, so as to achieve the effect of changing the air inlet position of the air inlet duct 11.

[0030] After the sea air no longer enters the air inlet duct 11 through the air guide 12, the control terminal starts the first driving member 20 located on the lower side, and the first driving member 20 located on the lower side drives the adjacent fixed rod 18 and the roller 19 to rotate. During the rotation of the roller 19, the adjacent filter screen 191 is rolled up, so that the filter screen 191 in contact with impurities and plankton is rolled up onto the left roller 19. During the rotation of the left roller 19, the filter screen 191 moves to the left, and the filter screen 191 drives the two adjacent fixed rings 31 to rotate (the above descriptions are all the movement states of the lower roller 19, the filter screen 191 and their attached parts).

[0031] Taking the rotation process of one of the fixing rings 31 as an example, the fixing ring 31 drives the adjacent first extrusion blocks 32 distributed in a ring array to rotate, and the first extrusion blocks 32 squeeze the adjacent limiting members 30, so that the limiting members 30 slide to the side away from the fixing rod 18 (the adjacent tension spring is stretched during the sliding process of the limiting members 30). As the fixing ring 31 rotates, the first extrusion blocks 32 squeeze the adjacent limiting members 30, and the limiting members 30 are separated from the contact with the adjacent limiting grooves on the adjacent fixing rods 18, thereby releasing the limiting of the fixing ring 31 and the adjacent filter screen 191, so that the filter screen 191 can be stretched and wound onto the left roller 19 (the above descriptions are all the movement states of the lower roller 19, the filter screen 191 and their attached parts).

[0032] When the left roller 19 has rolled up the filter screen 191 in contact with impurities and plankton, the filter screen 191 is no longer stretched, and the two fixed rings 31 stop rotating at this time. Under the action of the adjacent tension springs of the limiting member 30, the two adjacent first extrusion blocks 32 drive the adjacent fixed rings 31 to reset and rotate. During the reset and rotation of the fixed ring 31, the adjacent sides of the filter screen 191 are stretched in the opposite direction. Under the action of the adjacent tension springs, the limiting member 30 is reinserted into the adjacent limiting grooves on the adjacent fixed rods 18 to limit the fixing ring 31 and the adjacent filter screen 191, so as to prevent the fixing ring 31 from driving the adjacent sides of the filter screen 191 to rotate arbitrarily, thereby reducing the filtration efficiency (the above descriptions are all the movement states of the lower roller 19, the filter screen 191 and their accessory parts).

[0033] After the filter screen 191 is rolled up, the control terminal closes the first driving member 20 on the lower side, and then starts the second driving member 46. The second driving member 46 drives the first gear 47 to rotate. During the rotation of the first gear 47, the two first rack racks 40 drive the adjacent sliding seats 41 to move toward each other. During the movement of the two sliding seats 41 toward each other, all the swing plates 42 are retracted.

[0034] Taking the swinging process of one of the swinging plates 42 as an example, during the swinging process, the swinging plate 42 swings along the adjacent connecting seat 43 and the adjacent connecting frame 44 or the adjacent sliding seat 41. When the lower side of the swinging plate 42 swings along the adjacent connecting seat 43, the elastic rope 53 pulls the adjacent shielding plate 50 downward, so that the shielding plate 50 slides along the lower side of the adjacent swinging plate 42 and squeezes the adjacent spring. During the downward movement of the shielding plate 50, the through hole in the lower half of the adjacent swinging plate 42 is blocked. During the rotation of the upper side of the swinging plate 42 along the adjacent connecting frame 44 or the adjacent sliding seat 41, the rotating shell 54 pulls the adjacent shielding plate 50 through the connecting rope, so that the shielding plate 50 slides along the upper side of the adjacent swinging plate 42 and squeezes the adjacent spring. During the upward movement of the shielding plate 50, the through hole in the upper half of the adjacent swinging plate 42 is blocked.

[0035] When the swing plate 42 continues to swing along the adjacent connecting seat 43, the elastic rope 53 is stretched, and the shielding plate 50 on the lower side has slid to fit the lower side of the adjacent swing plate 42. When the swing plate 42 continues to swing along the connecting frame 44 or the adjacent sliding seat 41, the rotating shell 54 drives the adjacent torsion spring to be gradually tightened, and the shielding plate 50 on the upper side has slid to fit the upper side of the swing plate 42, so as to prevent the swing plate 42 from sliding. Fig. 9 Taking the process of the two swinging plates 42 swinging toward each other as an example, the two adjacent filter elements 45 are squeezed during the swinging process of the two swinging plates 42, so that the water vapor absorbed by the filter elements 45 is squeezed (under the effect of the two shielding plates 50 blocking the rectangular array distribution through holes on the adjacent swinging plates 42, the water vapor will not fall downward when the filter elements 45 are squeezed), and then flows into the V-shaped groove in the adjacent connecting seat 43, and the V-shaped groove in the connecting seat 43 then transfers the water vapor to the adjacent liquid guide tube 51. Through the above operation, the water vapor in the filter element 45 is processed, and the above process is completed without delaying the normal air intake of the air intake duct 11.

[0036] When the position of the filter 191 is replaced and the water vapor in the filter element 45 is processed, the control terminal controls the second driving member 46 to drive the first gear 47 to rotate in the opposite direction. During the reverse rotation of the first gear 47, the two first rack racks 40 drive the adjacent sliding seats 41 to move in opposite directions. During the opposite movement of the two sliding seats 41, all the swing plates 42 are expanded.

[0037] by Fig. 9 Taking the process of the two swinging plates 42 swinging back to back as an example, during the process of the lower side of the swinging plate 42 swinging in the opposite direction along the adjacent connecting seat 43, the elastic rope 53 returns to the state before being stretched, and the lower side shielding plate 50 moves to the upper side of the shielding plate 50 under the action of the adjacent spring and contacts the middle part of the adjacent swinging plate 42. At this time, the through holes in the lower half of the adjacent swinging plate 42 are connected with the through holes distributed in a rectangular array on the adjacent shielding plate 50. During the process of the upper side of the swinging plate 42 continuing to swing along the connecting frame 44 or the adjacent sliding seat 41, the rotating shell 54 rotates under the action of the torsion spring and returns to the state before being stretched, and the upper side shielding plate 50 moves to the lower side of the shielding plate 50 under the action of the adjacent spring and contacts the middle part of the adjacent swinging plate 42. At this time, the through holes in the upper half of the adjacent swinging plate 42 are connected with the through holes distributed in a rectangular array on the adjacent shielding plate 50.

[0038] After the swinging state of several swing plates 42 is restored to the state before swinging, the control terminal closes the second driving member 46, and then the control terminal controls the upper electric shutter 13 to block the left side of the air inlet duct 11, and finally the control terminal controls the lower electric shutter 13 to release the blocking of the air guide member 12, so that the air intake of the air inlet duct 11 is restored to the lower side intake. When the sea air is no longer needed to be transferred, the control terminal closes the exhaust member 14.

[0040] like Figure 11-13 As shown, the second driving assembly includes an L-shaped frame 70, which is fixedly connected to the first rack frame 40 located on the right side, and the L-shaped frame 70 is fixedly connected to the second rack frame 71 that passes through the air guide 12. The upper side of the fixed frame 63 is rotationally limited and connected to the second gear 72, and the second gear 72 is in transmission cooperation with the second rack frame 71. The sliding rod 64 is fixedly connected to a fixing member 73, and the fixing member 73 is located below the second gear 72. A spring is arranged between the fixing member 73 and the second fixing plate 62, and this spring is used to drive the fixing member 73 to slide. The fixing frame 63 is fixedly connected to one side facing the second fixing plate 62 with a second extrusion block 74 distributed in a ring array, and the cross-section of the second extrusion block 74 is triangular, and the second extrusion block 74 is extruded and cooperated with the adjacent fixing member 73. A stress buffer component for buffering the stress of the adjacent filter screen 191 is arranged on the L-shaped frame 70.

[0041] like Figure 11-13As shown, the stress buffer assembly includes a second elastic telescopic rod 8, which is fixed to the right side of the air guide 12 and is located above the first elastic telescopic rod 16. The telescopic end of the second elastic telescopic rod 8 is fixedly connected to a first oil storage member 80, and a first piston rod 81 is sealed and slidably connected in the first oil storage member 80. The right end of the first piston rod 81 is fixedly connected to the adjacent side of the L-shaped frame 70, and a second oil storage member 82 is fixedly connected to the right side of the L-shaped block 65. Hydraulic oil is stored in the second oil storage member 82 and the first oil storage member 80. The first oil storage member 80 and the second oil storage member 82 are connected to each other. A connecting pipe for connecting the two is fixedly connected to the opposite side of the oil piece 82, and a second piston rod 83 is sealingly and slidably connected inside the second oil storage piece 82. The diameter inside the first oil storage piece 80 is larger than the diameter inside the second oil storage piece 82, and the volumes inside the first oil storage piece 80 and the second oil storage piece 82 are consistent, which is used to amplify the movement stroke of the second piston rod 83. A spring that is squeezed and matched with the second piston rod 83 is provided in the second oil storage piece 82. This spring is used to drive the second piston rod 83 to reset and slide. The second piston rod 83 is fixedly connected to the second magnetic attraction piece 66 via a connecting rod.

[0042] When processing the filter screen 191 on the lower side, this embodiment will not directly drive the adjacent fixing rod 18 and the roller 19 to rotate through the first driving member 20 on the lower side, and will not preferentially reel up the adjacent filter screen 191.

[0043] During the process of the two first rack racks 40 moving toward each other, the first rack rack 40 on the right side drives the second rack rack 71, the first piston rod 81 and the adjacent second U-shaped rack 17 to move to the left side, and the first piston rod 81 transports the hydraulic oil in the first oil storage part 80 to the second oil storage part 82 through the adjacent connecting pipe, so that the second piston rod 83 drives the connecting rod and the second magnetic member 66 to move to the left side (the adjacent spring is squeezed during the movement of the second piston rod 83), and the second magnetic member 66 drives the first magnetic member 61 to slide to the left side along the sliding frame 60 and squeeze the adjacent spring. Under the comparison of the inner diameters of the first oil storage part 80 and the second oil storage part 82, the moving speed of the second piston rod 83 is faster than that of the first piston rod 81, so as to realize the movement of the second piston rod 83 and the second magnetic member 66 in a short time. After the first piston rod 81 moves to its left side and fits into the first oil storage part 80, the telescopic end of the second elastic telescopic rod 8 is compressed.

[0044] During the movement of the second magnetic member 66 and the first magnetic member 61 to the left, the left side of the adjacent filter screen 191 becomes loose. During the movement of the second U-shaped frame 17 to the left, the telescopic portion of the adjacent second elastic telescopic rod 8 is squeezed. Then, the right side of the filter screen 191 is driven by the second U-shaped frame 17 to move, so that the right side of the adjacent filter screen 191 becomes loose. Through the above-mentioned actions, the adjacent filter screen 191 becomes loose, thereby facilitating the treatment of impurities and plankton on the filter screen 191.

[0045] When the second rack 71 moves with the L-shaped frame 70 to contact the second gear 72, the second rack 71 drives the second gear 72 to rotate, and the second extrusion blocks 74 distributed in the annular array are driven to rotate by the second gear 72, the sliding rod 64 and the fixing member 73. During the rotation of the second extrusion block 74, the inclined surface on the second extrusion block 74 squeezes the fixing member 73, so that the fixing member 73 drives the sliding rod 64, the L-shaped block 65, the second magnetic member 66, the first magnetic member 61 and the adjacent filter 191 to slide downward, and the fixing member 73 and the first When the magnetic component 61 drives the sliding frame 60 to slide downward, the adjacent springs are squeezed respectively. After the fixing component 73 is no longer in contact with the inclined surface of the adjacent second squeezing block 74, under the action of the fixing component 73 and the adjacent springs of the sliding frame 60, the first magnetic component 61 and the second magnetic component 66 drive the adjacent filter screen 191 to move upward to reset. The adjacent filter screen 191 is cleaned by the vibration force generated by the up and down sliding of the first magnetic component 61 and the second magnetic component 66, so as to realize daily cleaning without replacing all the adjacent filter screens 191.

[0046] When the daily cleaning of the filter 191 is completed, the first rack rack 40 on the right side drives the L-shaped rack 70 and its attached parts to reset and slide. When the second rack rack 71 moves with the L-shaped rack 70 to no longer contact the second gear 72, the telescopic parts of the two second elastic telescopic rods 8 are gradually reset. The second U-shaped rack 17 on the right side pulls the right side of the adjacent filter 191 to restore the right side of the adjacent filter 191 to a flat state. After the telescopic end of the upper second elastic telescopic rod 8 is reset, the L-shaped rack 70 and the first piston rod 81 continue to move to the right, so that the hydraulic oil in the second oil storage part 82 is transferred to the first oil storage part 80 through the adjacent connecting pipe. The second piston rod 83 drives the second magnetic suction part 66 to reset and move through the connecting rod under the action of the adjacent spring, so that the second magnetic suction part 66 and the first magnetic suction part 61 drive the left side of the adjacent filter 191 to move. When the left side of the adjacent filter 191 moves to a flat state, the first rack rack 40 on the right side has moved to Fig.11 The basic state in .
