Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 12 , the embodiments of the present invention provide a technical solution: a mobile cooling and filtering structural unit, including a bottom plate 1, a support rod 2, directional rollers 21 and universal rollers 3. One side of the bottom surface of the bottom plate 1 is rotatably connected to the support rod 2 through a bearing. The two ends of the support rod 2 are symmetrically fixed with directional rollers 21. The bottom of the bottom plate 1 is symmetrically fixed with universal rollers 3 on the side far from the support rod 2. The universal rollers 3 are used to operate the device for steering work, and the directional rollers 21 are used for support and for rolling;

[0038] An air cooling device 4 is fixed on the bottom plate 1. The air inlet end of the air cooling device 4 is connected to an air pump 5. The air pump 5 is fixed to the bottom plate 1. The air inlet end of the air pump 5 is fixed with an air delivery pipe 51 fixed to the bottom plate 1. A frame-shaped support portion 101 is formed on the bottom plate 1. The air cooling device 4, the air pump 5 and the air delivery pipe 51 are all fixed to the frame-shaped support portion 101. When the unit is in use, by driving the air pump 5 to work, the air in the site is sucked into the inner side of the air delivery pipe 51 through the air inlet end of the air delivery pipe 51 and then enters the air cooling device 4 through the air pump 5 for cooling work. The air cooling device 4 is a prior art, and its specific structure will not be elaborated here;

[0039] A push handle 10 is also fixed on the top of the bottom plate 1 near the frame-shaped support portion 101. When moving the entire unit, workers push it by holding the push handle 10, so that the entire device moves;

[0040] A support structure 6 for supporting a plurality of air filter cores 7 is slidably installed on the bottom plate 1. The plurality of air filter cores 7 are arranged equidistantly on the support structure 6, and the end of one of the plurality of air filter cores 7 is pressed against the air inlet end of the air delivery pipe 51. A pressing mechanism 8 capable of driving the support structure 6 to slide and pressing one of the air filter cores 7 against the end of the air delivery pipe 51 and mechanically linked to the support rod 2 is also installed on the bottom plate 1. A synchronous switching mechanism 9 for automatically switching the position of the air filter core 7 when the support structure 6 slides away from the air inlet end of the air delivery pipe 51 is also installed on the support structure 6;

[0041] During use, one air filter element 7 at the uppermost end is pressed against the support structure 6 by the pressing mechanism 8 and thus pressed against the intake end of the air delivery pipe 51. When air enters at the intake end of the air delivery pipe 51, it can suck in the air on the site, pass through the air filter element 7, and enter the inside of the air delivery pipe 51. The air filter element 7 filters the air. When the entire device moves a certain distance and the used air filter element 7 reaches the limit of its service life, the set synchronous switching mechanism 9, support mechanism, and pressing mechanism 8 can work simultaneously. The final effect is that the support structure 6 slides to the side away from the intake end of the air delivery pipe 51. During the sliding process, it can synchronously drive the six air filter elements 7 to rotate by 60 degrees, turning the failed filter element to one side and rotating the new filter element to the position for filtering work. As the entire unit continues to move, the pressing device after switching continues to press the support mechanism and one air filter element 7 at the uppermost end against the intake end of the air delivery pipe 51, completing the automatic switching work of the air filter element 7 without manual switching, ensuring the timeliness of switching, avoiding waste of the filter element caused by premature switching, and at the same time avoiding the phenomenon of a decrease in air filtration quality due to switching filtration.

[0042] The support structure 6 includes a support plate 61. The support plate 61 is slidably connected to the top surface of the bottom plate 1 through two symmetrically arranged first linear guide rails 62. The upper end of the support plate 61 is rotatably connected to a support rotating shaft 63 through a bearing. Six support sleeves 64 are fixedly arranged at equal angles at one end of the support rotating shaft 63 close to the air delivery pipe 51. Two connecting pieces 631 are symmetrically formed on one side of the support rotating shaft 63 close to the support sleeve 64. The two ends of the support sleeve 64 are respectively fixed to the two connecting pieces 631. The air filter element 7 is press-fitted into the inner side of the support sleeve 64. The air filter element 7 can just be inserted into the inner side of the support sleeve 64 and form an interference connection without being subjected to a large manual pulling force, so that the air filter element 7 will not slide out of the inner side of the support sleeve 64 at will, thus ensuring that the position of the air filter element 7 in the remaining support sleeves 64 will not be affected during the automatic switching process of the daily air filter element 7.

[0043] One end of the air filter element 7 at the uppermost end is pressed against the intake end of the air delivery pipe 51. Openings 641 are formed at equal intervals on the side wall of the support sleeve 64. The openings 641 are for air to smoothly enter the inner side of the support sleeve 64 and then pass through the air filter element 7. The end of the support sleeve 64 has no opening 641 so that the end of the air filter element 7 can be pressed against the end of the inner wall of the support sleeve 64 to form a seal. Most of the existing air filter elements 7 are sleeve-shaped with openings 641 at both ends. This setting ensures that the air on the site can smoothly pass through the filtering part of the air filter element 7.

[0044] The clamping mechanism 8 includes a reducer 81, a reducer 81 is fixed to the bottom of the base plate 1, a driven bevel gear 82 is fixed to the input end of the reducer 81, an active bevel gear 83 is fixed to the outer wall of the support rod 2, the active bevel gear 83 is meshed and connected with the driven bevel gear 82, the output end of the reducer 81 passes through the base plate 1 and extends to the top of the base plate 1, and a push plate 84 is fixed to the output end of the reducer 81, a notch 841 is formed on the outer periphery of the push plate 84, and the bottom of the support plate 61 is away from the side of the push plate 84 A first spring 85 is fixed, and the side of the first spring 85 away from the push plate 84 is fixed to the top of the bottom plate 1. A passive rod 86 is fixed to the side of the bottom of the support plate 61 close to the push plate 84. The end of the passive rod 86 is in compression contact with the outer periphery of the push plate 84. The passive rod 86 is arranged in a semicircular shape close to the outer periphery of the push plate 84. The semicircular shape is mainly to enable the end of the passive rod 86 to slide smoothly on the outside of the push plate 84 during daily use. In other words, it is to facilitate the smoother rotation of the push plate 84.

[0045] The specific use process of the clamping mechanism 8 is as follows: during daily use of the unit, the directional roller 21 rotates to rotate the support rod 2, driving the active bevel gear 83 to rotate and drive the driven bevel gear 82 to rotate, thereby rotating the input end of the reducer 81. After the deceleration of the reducer 81, the output end of the reducer 81 rotates slowly, and the push plate 84 rotates slowly until the push plate 84 completes a circle of rotation, and an air filter element 7 just reaches the limit of use. At this time, the notch 841 is facing the passive rod 86. Under the action of the rebound force of the first spring 85, the support plate 61 is pulled to drive the passive rod 86 to slide toward the inner side of the notch 841 on the push plate 84, and then the passive rod 86 is pressed against the inner side of the notch 841. In this process, the entire support structure 6 will slide to the side close to the notch 841, so that an air filter element 7 facing the end of the air supply pipe 51 is separated from the air supply pipe 51;

[0046] The synchronous switching mechanism 9 includes a six-slot wheel 91. One end of the support rotating shaft 63 away from the support sleeve 64 is fixedly provided with the six-slot wheel 91. One side of the support plate 61 close to the six-slot wheel 91 is rotatably connected with a connecting shaft 92 through a bearing. The end of the connecting shaft 92 is fixedly provided with a driving wheel 93. The driving wheel 93 is matched with the six-slot wheel 91. A driven gear 94 is also installed on the outer wall of the connecting shaft 92 through a one-way bearing. One side of the support plate 61 close to the driven gear 94 is slidably connected with a rack 95 through a second linear guide 96. The two ends of the second linear guide 96 are symmetrically fixedly provided with second limit blocks 97. The rack 95 is meshed and connected with the driven gear 94. A second spring 98 is fixedly provided on the outer wall of the rack 95 away from the driven gear 94. One end of the second spring 98 away from the rack 95 is fixedly connected with the outer wall of the support plate 61. A passive block 99 is fixedly provided at the lower end of the outer wall of the rack 95 close to the second spring 98. One side of the support plate 61 close to the passive block 99 is slidably connected with a driving block 911 through a third linear guide 910. The driving block 911 faces the passive block 99. The two ends of the third linear guide 910 are symmetrically fixedly provided with third limit blocks 912. A third spring 913 is fixedly provided on the upper outer wall of the driving block 911. The upper end of the third spring 913 is fixedly connected with the outer wall of the support plate 61. A cable 914 is fixedly provided at the lower end of the driving block 911. The lower end of the cable 914 extends to the lower surface of the support plate 61 and is fixedly connected with the surface of the bottom plate 1 after passing around the corner at the lower end of the support plate 61. A plurality of guide rings 915 are fixedly provided on the outer wall of the support plate 61 along the cable 914. The cable 914 passes through the guide rings 915;

[0047] The synchronous switching mechanism 9 is on the side where the entire support structure 6 slides toward the notch 841. Since the end of the cable 914 fixed on the bottom plate 1 cannot move, the support plate 61 slides toward the notch 841. The sliding in this direction causes the cable 914 to be pulled, thereby pulling the driving block 911 through the cable 914, so that the driving block 911 stretches the third spring 913 and slides downward. After sliding a certain distance, the driving block 911 contacts the passive block 99. In the process of continuing to slide, the driving block 911 pulls the passive block 99 together to overcome the second The elastic force of the spring 98 and the third spring 913 pulls the rack 95 downward to slide, and it should be emphasized that the rebound force of the first spring 85 is much greater than the sum of the rebound forces of the second spring 98 and the third spring 913. After the support structure 6 moves a certain distance, the rack 95 slides downward to turn the gear to rotate. Finally, when the passive rod 86 is pressed against the inner wall of the notch 841, the support plate 61 slides to the position closest to the push plate 84. At this time, the rack 95 drops to the lowest position, just turning the gear to rotate one circle. In this direction, the gear is made to rotate by the action of the one-way bearing. The rotation can drive the connecting shaft 92 to rotate, thereby driving the driving wheel 93 to rotate one circle, so that the six-way groove wheel 91 rotates 60 degrees, so that the support shaft 63 rotates and drives the six support sleeves 64 to rotate, thereby achieving the effect of switching the air filter element 7. After the switching is completed, the trolley continues to move a certain distance, so that the notch 841 rotates to stagger the passive rod 86 so that it is pressed against the outer periphery of the push plate 84 again. This process makes the support structure 6 reset and slide, and finally presses the air filter element 7 against the air inlet end of the air supply pipe 51 through the push plate 84. , and during the resetting process of the support structure 6, the rack 95 slides up and resets under the action of the rebound force of the second spring 98 and the third spring 913, and the drive block 911 slides up and resets. Finally, the rack 95 and the drive block 911 are respectively pressed against the second limit block 97 at the upper end and the third limit block 912 at the upper end. The rack 95 resets the gear and rotates. Under the action of the one-way bearing, it cannot drive the connecting shaft 92 to rotate. Therefore, the entire support shaft 63 will not rotate anymore, thereby completing the switching work, and then the air filtering and cooling work can continue.

[0048] The present invention also provides a filtering system with a mobile cooling filtering structural unit, comprising the mobile cooling filtering structural unit.

[0049] The present invention also provides a method for using a filtration system with a mobile cooling filtration structural unit. The filtration system with a mobile cooling filtration structural unit is used to filter and cool the air in a factory. The specific steps include the following:

[0050] 1) Pushing the bottom plate 1 to move along a fixed route in the factory;

[0051] 2) During the movement, the air pump 5 operates to suck air, so that the air passes through an air filter element 7 docked with the air delivery pipe 51 for filtration, and then enters the air cooling device 4 for cooling and is discharged;

[0052] 3) As the usage duration increases, the moving distance of the bottom plate 1 increases, and the automatic switching operation of the air filter element 7 can be completed by using the support structure 6, the synchronous switching mechanism 9 and the pressing mechanism 8, achieving the effect of automatically replacing the filter element.
