[0009] Preferably, a rack is meshingly connected below the gear, and a sliding groove is provided on the surface of the rack opposite to the bracket, and a slider on the surface of the bracket is placed in the sliding groove, thereby enabling the rack to slide and displace at a specific lateral position.

[0010] Preferably, a worm gear is arranged on the outer circumference of the dust removal cylinder opposite to the rack, and a rotating shaft is integrally fixed after penetrating the wall of the dust removal cylinder from one side of the worm gear, and a telescopic cylinder is fixed at the other end of the rotating shaft, and one end of the telescopic cylinder opposite to the rack is open.

[0011] Preferably, a telescopic column is extended from one end of the rack into the telescopic cylinder, a reciprocating groove is provided on the inner ring wall of the telescopic cylinder, and one end of an insert provided on the outer circumference of the telescopic column extends into the reciprocating groove.

[0012] Preferably, a worm is meshingly connected below the worm wheel, and the rotation of the worm is supported by a rotating frame provided on the outer circumference of the dust removal cylinder, and a pulley is fixed to one end of the worm.

[0013] Preferably, the fan is composed of rotatable blades, a second pulley is fixed to one end of the blade opposite to the surface of the filter cotton, and a belt is sleeved between the first pulley and the second pulley.

[0014] Preferably, both side ends of the rotating arm 1 are respectively provided with a telescopic groove 1 inwardly, a guide column capable of telescopic displacement is also provided inside the telescopic groove 1, and a spring 1 for the guide column to rebound is also sleeved on the outer circumference of the telescopic groove 1.

[0015] Preferably, a scraper for scraping dust off both sides of the inner ring wall of the dust removal cylinder is fixed to the other end of the guide column, and guide plates capable of guiding the displacement of the scraper are arranged on both sides of the inner ring wall of the dust removal cylinder.

[0016] Preferably, movable groove 1 and movable groove 2 are respectively provided on the surface of the guide plate opposite to one end of the scraper, and movable groove 1 is close to the inner ring wall of the dust collector. The two ends of movable groove 1 and movable groove 2 form a connecting loop, and the movable groove 1 above the guide plate is not fixed with a magnetic block 3 for magnetically attracting the scraper, and the magnetic block 2 provided at one end of the scraper extends to movable groove 1, and the pull-out box for collecting dust below the dust collector is slidably inserted in the opening, and the opening passes through and is opened below the filter baffle.

[0017] The ship display and control console of the present invention has the following advantages:

[0018] 1. A ship display and control console. When the fan blades rotate, they guide the air through the filter baffle and filter cotton for preliminary purification. At the same time, the negative ion generator produces negative ions to remove particles in the air. The fan blades also drive a series of mechanical parts through the belt: first the pulley 1, then the worm and worm gear. This causes the reciprocating groove in the telescopic cylinder to drive the rack to move horizontally, which in turn causes the gear 1 and the rotating arm 1 to rotate around the axis. This process expands the range of the negative ion generator and improves the purification efficiency.

[0019] 2. In this ship display and control console, when the negative ion generator is running, the dust dropped during the purification process accumulates on both sides of the inner ring wall of the dust removal cylinder. The rotating arm 1 is driven to swing back and forth by the rack, and the scraper at its end is lifted by the action of the moving groove 2, and is tightly attached to the inner wall of the dust removal cylinder through the magnetic adsorption of the magnetic block 3 and the magnetic block 2. As the rotating arm 1 rotates, the scraper scrapes off the dust on the inner wall, and the dust is collected in the pull-out box. When the scraper moves upward in the opposite direction, the elastic force of the spring 1 keeps it away from the inner wall, ready for the next cleaning.

[0020] 3. In this ship display and control console, when the filter cotton has been used for a long time, the fan blades will rotate in the opposite direction for cleaning. At this time, pull out the pull-out box, and the airflow blows in the opposite direction to the filter cotton, so that the impurities adhering to its surface fall off. As the fan blades rotate in the opposite direction, the rotating wheel also starts to rotate in the opposite direction through the magnetic effect. In this process, the ratchet drives the rotating arm 2 to rotate continuously. The brush shaft rotates with the drive of the crown gear, and the soft brush on its outer circumference touches the filter cotton to help further remove residual impurities. This design can not only effectively remove dirt on the filter cotton, but also extend the service life of the filter cotton. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1-Figure 5 As shown, a ship display console of the present invention includes a display component 11 for display, and a cabinet 1 for protection under the display component 11. The interior of the cabinet 1 is a hollow structure, and a baffle 12 is fastened by bolts on one side of the outer surface of the cabinet 1. The display console can be repaired or maintained by disassembling and assembling the baffle 12. A filter baffle 121 for air intake and heat dissipation is also installed on the surface of the baffle 12, and a filter cotton 22 for filtering air is fixed at the air outlet end of the filter baffle 121. The gas entering the cabinet 1 can be filtered through the filter cotton 22 to prevent a large amount of dust from affecting the normal operation of the display console.

[0043] A dust collector 2 is fixed to the surface of the filter baffle 121 on the same side as the filter cotton 22. At the same time, the filter cotton 22 is fixedly installed coaxially with the dust collector 2, and a fan 3 for exhausting air is arranged opposite to the air outlet surface of the filter cotton 22. After the fan 3 is running, its airflow can be filtered by the filter cotton 22 and then blown into the cabinet 1, thereby achieving a filtering effect.

[0044] like Figure 4-Figure 9As shown, negative ion generators 21 for dust removal are fixed on both sides of the outer circumference of the dust removal tube 2, and an extension line 211 extends from one end of the negative ion generator 21 to the inside of the dust removal tube 2. The emission end 212 of the extension line 211 can be used to remove the air passing through the filter cotton 22, thereby achieving the effect of dust removal and extending the service life of the filter cotton 22.

[0045] A bracket 24 is provided on the bottom surface of the inner ring wall of the dust collecting cylinder 2 and extends to the top. The center of the bracket 24 overlaps with the axis of the dust collecting cylinder 2. The rotating arm 4 that can rotate is coaxially arranged with the center of the bracket 24 through a rotating shaft. The gear 41 provided on the other side of the bracket 24 is connected to the rotating arm 4, so that the gear 41 can be driven to rotate together after the rotating arm 4 rotates. The transmitting end 212 at the end of the extension line 211 is fixed to both sides of the rotating arm 4, so that a certain distance is formed between the two transmitting ends 212.

[0046] A rack 523 is meshed and connected below the gear 1 41. A sliding groove 521 is provided on the surface of the rack 523 opposite to the bracket 24, and a slider 241 on the surface of the bracket 24 is placed in the sliding groove 521, so that the rack 523 can slide and move to a specific lateral position. After the rack 523 slides and moves, the gear 1 41 can rotate.

[0047] A worm wheel 5 is arranged on the outer circumference of the dust collecting cylinder 2 opposite to the rack 523. A rotating shaft 51 is fixed integrally after penetrating the wall of the dust collecting cylinder 2 from one side of the worm wheel 5. A telescopic cylinder 511 is fixed on the other end of the rotating shaft 51. One end of the telescopic cylinder 511 opposite to the rack 523 is open. A telescopic column 52 extends from one end of the rack 523 to the inside of the telescopic cylinder 511. A reciprocating groove 512 is arranged on the inner ring wall of the telescopic cylinder 511. The reciprocating groove 512 is composed of two thread grooves with the same pitch and opposite rotation directions, and is connected at both ends by a transition curve. In addition, one end of the insert block 522 arranged on the outer circumference of the telescopic column 52 extends to the inside of the reciprocating groove 512. Therefore, after the telescopic cylinder 511 rotates, the rack 523 can be moved back and forth horizontally.

[0048] A worm 232 is meshedly connected below the worm wheel 5, and the rotation of the worm 232 is supported by a rotating frame 23 provided on the outer circumference of the dust removal cylinder 2, and a pulley 231 is fixed to one end of the worm 232. As the pulley 231 rotates, the worm wheel 5 meshed above can be driven by the worm 232.

[0049] The fan 3 for exhausting air is composed of rotatable blades 31, and a pulley 2 311 is fixed to one end of the blades 31 opposite to the surface of the filter cotton 22. The pulley 2 311 is arranged parallel to the pulley 1 231 on the same side, and a belt 313 is sleeved between the pulley 1 231 and the pulley 2 311. Therefore, when the display and control console is used on a ship, the fan blade 31 can rotate at this time. As the fan blade 31 rotates, the airflow outside the display and control console can slowly pass through the filter baffle 121 and the filter cotton 22. When the airflow passes slowly, dust is removed by the negative ion generator 21. When the fan blade 31 rotates, the pulley 231 can be driven by the belt 313. After the pulley 231 rotates, the worm 232 can drive the worm wheel 5 meshing above. At the same time, when the worm wheel 5 rotates, the reciprocating groove 512 on the inner ring wall of the telescopic cylinder 511 can drive the rack 523 to continuously move back and forth horizontally. As the rack 523 moves back and forth, it can push the gear 41, and then the rotating arm 4 can rotate with the axis as the axis, thereby expanding the purification range of the negative ion generator 21, improving its purification effect, and extending the service life of the filter cotton 22.

[0050] like Figure 2 and Figure 11-Figure 15 As shown, telescopic grooves 42 are respectively opened inwardly at the two side ends of the rotating arm 4, and one end of a guide column 43 capable of telescopic displacement is placed inside the telescopic groove 42, so that the guide column 43 can be displaced along the depth of the telescopic groove 42, and a spring 431 for the guide column 43 to rebound is also sleeved on the outer circumference of the telescopic groove 42.

[0051] A scraper 432 for scraping dust on both sides of the inner ring wall of the dust removal cylinder 2 is fixed at the other end of the guide column 43. At the same time, a guide plate 6 capable of guiding the displacement of the scraper 432 is arranged on both sides of the inner ring wall of the dust removal cylinder 2. A movable groove 1 61 and a movable groove 2 62 are respectively provided on the surface of the guide plate 6 opposite to one end of the scraper 432. The movable groove 1 61 is close to the inner ring wall of the dust removal cylinder 2. The two ends of the movable groove 1 61 and the movable groove 2 62 form a connecting loop. A magnetic block 3 611 for magnetically attracting the scraper 432 is not fixed inside the movable groove 1 61 above the guide plate 6, and the magnetic block 2 433 provided at one end of the scraper 432 extends to the movable groove 1 61.

[0052] The pull-out box 13 for collecting dust located below the dust collecting cylinder 2 is slidably inserted into the opening 14, and the opening 14 is opened below the filter baffle 121. Therefore, when the negative ion generator 21 is running to remove dust, the dust that falls at this time will fall to both sides of the inner ring wall of the dust collecting cylinder 2, and when the rotating arm 14 is driven by the rack 523 to swing back and forth, the scraper 432 at one end of the rotating arm 14 is moved to the high end by the moving groove 2 62, and the magnetic block 3 611 can magnetically absorb the magnetic block 2 433, so that one end of the scraper 432 can contact the inner ring wall of the dust collecting cylinder 2, and then when the rotating arm 14 rotates, the scraper 432 on one side can scrape the inner ring wall of the dust collecting cylinder 2, and then be collected by the pull-out box 13, and when the scraper 432 moves upward in the opposite direction, due to the elastic force of the spring 1 431, the scraping end of the scraper 432 can be pushed back away from the inner ring wall of the dust collecting cylinder 2.

[0053] like Figure 8-Figure 18 As shown, after the filter cotton 22 is used, some impurities will accumulate on its filtering side, and these impurities will affect the filtering effect of the filter cotton 22. A second rotating frame 242 is fixed to the upper end of one side of the outer surface of the bracket 24, and the axis of the second rotating frame 242 is concentrically arranged with the axis of the bracket 24, and a second rotating arm 7 that can rotate is coaxially arranged on one side of the second rotating frame 242, and a certain rotational friction resistance is formed at the rotation point of the second rotating arm 7 and the second rotating frame 242, and the rotational friction resistance is used to overcome the rotation of the rotating wheel 74.

[0054] Two pairs of rotating frames 3 71 are fixed on the surface of the rotating arm 2 7 facing the filter cotton 22, and the brush shaft 72 that can rotate and lightly sweep the surface of the filter cotton 22 is arranged in the interval between the two rotating frames 3 71. A gear 2 721 is fixed on one end of the brush shaft 72 close to the inner ring wall of the dust removal cylinder 2, and the gear 2 721 is meshed and connected with the crown gear 25 provided on the inner ring wall of the dust removal cylinder 2. Therefore, when the rotating arm 2 7 rotates, the gear 2 721 at one end of the brush shaft 72 is meshed with the crown gear 25, so that the brush shaft 72 can rotate, and then the brush shaft 72 gently sweeps to assist in removing impurities on one side of the filter cotton 22.

[0055] A rotating chamber 73 on the same side as the rotating frame three 71 is coaxially arranged on the surface of the rotating arm two 7, and the rotating chamber 73 is an open structure at one end, and a rotatable rotating wheel 74 is coaxially arranged at the opening of the rotating chamber 73, and a ratchet 742 extends from the outer surface of the rotating wheel 74 to the inside of the rotating chamber 73, and a pawl 751 engaged with the ratchet 742 is arranged inside the rotating chamber 73, and one end of the pawl 751 is placed inside the telescopic groove two 75 provided on the outer peripheral surface of the rotating chamber 73, and a spring two 752 is arranged between the top of the pawl 751 and the top of the telescopic groove two 75. Through the cooperation between the ratchet 742 and the pawl 751, the rotating wheel 74 can be rotated in the correct direction to drive the rotating arm two 7 to rotate.

[0056] A magnetic block 4 741 is distributed on the surface of the rotating wheel 74, and a magnetic block 1 312 that attracts the magnetic block 4 741 is distributed on the surface of the pulley 2 311. Therefore, when the fan blade 31 rotates in the normal wind direction, the ratchet 751 will continuously move upward, and only the rotating wheel 74 rotates alone. After the filter cotton 22 rotates for a long time, when the fan blade 31 rotates in the reverse direction to remove dust, the pull-out box 13 is pulled out, and the airflow will blow in the reverse direction to the filter cotton 22, and then the impurities on the side of the filter cotton 22 that are adhered to the impurities will fall off, and through magnetism, the rotating wheel 74 rotates in the reverse direction at this time, and under the drive of the ratchet 742, the rotating arm 2 7 can be continuously rotated, and then the brush shaft 72 is driven by the crown gear 25, and the soft brush on the outer peripheral surface of the brush shaft 72 can touch the filter cotton 22 lightly, assisting in removing impurities and extending the service life of the filter cotton 22.

[0057] Working principle of a ship display and control console:

[0058] First, when it is applied on a display and control console ship, the fan blade 31 can rotate at this time. As the fan blade 31 rotates, the airflow outside the display and control console can slowly pass through the filter baffle 121 and the filter cotton 22. When the airflow passes slowly, the negative ion generator 21 is used for dust removal. When the fan blade 31 rotates, the pulley 231 can be driven by the belt 313. After the pulley 231 rotates, the worm 232 can drive the meshing worm wheel 5 above. At the same time, when the worm wheel 5 rotates, the reciprocating groove 512 on the inner ring wall of the telescopic cylinder 511 can drive the rack 523 to continuously move back and forth horizontally. As the rack 523 moves back and forth, it can push the gear 41, and then the rotating arm 4 can rotate with the axis as the axis, thereby expanding the purification range of the negative ion generator 21, improving its purification effect, and extending the service life of the filter cotton 22.

[0059] Secondly, when the negative ion generator 21 is running to remove dust, the dust that falls at this time will fall to both sides of the inner ring wall of the dust removal cylinder 2. When the rotating arm 14 is driven by the rack 523 to swing back and forth, the scraper 432 at one end of the rotating arm 14 is moved to the high end by the moving groove 2 62, and the magnetic block 3 611 can magnetically absorb the magnetic block 2 433, so that one end of the scraper 432 can be against the inner ring wall of the dust removal cylinder 2. Then, under the rotation of the rotating arm 14, the scraper 432 on one side can scrape the inner ring wall of the dust removal cylinder 2 and is immediately collected by the pull-out box 13. When the scraper 432 moves upward in the opposite direction, the scraper end of the scraper 432 can be pushed back by the elastic force of the spring 1 431, so that the scraping end of the scraper 432 can be away from the inner ring wall of the dust removal cylinder 2.

[0060] Finally, when the fan blade 31 rotates in the normal wind direction, the ratchet 751 will continue to move upward, and only the rotating wheel 74 will rotate alone. After the filter cotton 22 rotates for a long time, when the fan blade 31 rotates in the opposite direction for dust removal, the pull-out box 13 is pulled out, and the airflow will blow in the opposite direction to the filter cotton 22. Then the impurities on the side of the filter cotton 22 adhered to will fall off, and through magnetism, the rotating wheel 74 will rotate in the opposite direction, and under the drive of the ratchet 742, the rotating arm 27 can be continuously rotated, and then the brush shaft 72 is driven by the crown gear 25, and the soft brush on the outer peripheral surface of the brush shaft 72 can lightly touch the filter cotton 22 to assist in removing impurities and extend the service life of the filter cotton 22.

[0061] It should be noted that the specific models and specifications of the display component 11, the negative ion generator 21 and the fan 3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0062] The power supply and principle of the display assembly 11, the negative ion generator 21 and the fan 3 are clear to those skilled in the art and will not be described in detail here.
