Good environmental hygiene can prevent people from being harmed by viruses. Nowadays, one of the most stringent environmental hygiene controls is the laboratory. The laboratory is where people practice theoretical knowledge.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a highly efficient disinfection device for laboratory exhaust duct is proposed, the device comprising: The main frame 1 includes a mounting platform 101 disposed on the main frame 1, and a fixing plate 102 is fixedly mounted on the surface of the mounting platform 101; The wiping mechanism 2 includes two wiping soft ropes 201 in a loose state installed on the main frame 1. The wiping soft ropes 201 are arranged in a closed loop shape and are water-absorbent. Revolution mechanism 3: drives the wiping soft rope 201 to revolve through the driving mechanism 5; Follow-up mechanism 4: drives the wiping soft rope 201 to circulate and rotate through the revolution mechanism 3; Disinfection mechanism 6: used to store disinfectant in contact with the wiping cord 201; Lifting mechanism 7: used to drive the wiping soft rope 201 to move in the vertical direction.

[0020] In practical application, when the vertical pipeline is sterilized, Figure 1 As shown, at this time, the lifting mechanism 7 drives the wiping soft rope 201 to move to the entrance of the pipeline, as shown in FIG. Figure 2 and Figure 4 As shown, at this time, the wiping soft rope 201 is driven to revolve through the revolution mechanism 3 under the driving action of the driving mechanism 5. At this time, the surface of the wiping soft rope 201 will be tightened under the action of the centrifugal force, and the wiping soft rope 201 is in an expanded state under the limiting action of the follower mechanism 4, as shown in FIG. Figure 3As shown, the follow-up mechanism 4 is also driven to move synchronously through the action of the revolution mechanism 3. Under the action of the follow-up mechanism 4, the wiping soft rope 201 is driven to perform circular rotation. During the circular rotation, the wiping soft rope 201 absorbs disinfectant in the disinfection mechanism 6. At this time, after the wiping soft rope 201 contacts the inside of the pipeline, its expanded part contacts the inner wall of the pipeline, so that the inner wall of the pipeline is fully wiped and disinfected by the disinfectant attached to it. At the same time, the disinfectant is replenished from the disinfection mechanism 6 through its own circulation, thereby improving the disinfection efficiency. When the wiping soft rope 201 moves to the bent part of the pipeline under the action of the lifting mechanism 7, it can still be wiped by the contouring energy of the wiping soft rope 201. The force fully disinfects the bending position, thereby increasing the flexibility of the device. At the same time, since the length of the wiping soft rope 201 can be changed with actual use, pipes of different diameters can be cleaned, thereby increasing the flexibility of the device. At the same time, when the follow-up mechanism 4 drives the wiping soft rope 201 to rotate and circulate, the excess disinfectant adsorbed from the disinfection mechanism 6 is synchronously squeezed back into the disinfection mechanism 6 through the squeezing action of the follow-up mechanism 4, thereby avoiding the waste of disinfectant when the wiping soft rope 201 wipes and disinfects the inner wall of the pipe. At the same time, if there is too much disinfectant, the disinfectant will condense and drip on the pipe, thereby affecting the working environment, thereby achieving the purpose of quickly recovering the disinfectant.

[0021] like Figure 2 As shown, as a preferred embodiment of the present invention, the revolution mechanism 3 includes a rotating cylinder 301 installed on the main frame 1, a T-shaped cylinder 302 is fixedly installed on the inner wall of the rotating cylinder 301, a linkage disk 303 is fixedly installed on the surface of the rotating cylinder 301, and a connecting rod 304 is fixedly installed on the surface of the linkage disk 303.

[0022] In actual application of the embodiment of the present invention, when wiping and disinfecting the pipeline, Figure 2 As shown, at this time, the driving mechanism 5 drives the T-shaped cylinder 302 to rotate, and then the rotating cylinder 301, the linkage disk 303 and the connecting rod 304 are driven to rotate synchronously through the connection of the mechanism, thereby driving the wiping soft rope 201 to revolve, and the wiping soft rope 201 is driven to be in an expanded state through the action of centrifugal force, thereby performing contour contact with the inner wall of the pipeline, thereby improving the efficiency and flexibility of disinfection.

[0023] like Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, as another preferred embodiment of the present invention, the follower mechanism 4 includes two follower gears 401 rotatably connected to the T-shaped cylinder 302, a bevel gear set 402 is coaxially fixedly installed on the surface of each follower gear 401, each follower gear 401 is meshed with a fixed gear ring 403, the other end of the bevel gear set 402 passes through the T-shaped cylinder 302 and is rotatably connected to the T-shaped cylinder 302, a driving transmission wheel 404 is fixedly installed on the other end of the bevel gear set 402, and the inner wall of the rotating cylinder 301 is rotatably connected to the driven transmission wheel 404. 05, the internal teeth of the active transmission wheel 404 and the driven transmission wheel 405 are set to inclined hard rubber, a guide rod 406 is fixedly installed on the inner wall of the rotating cylinder 301, a guide hole is opened on the guide rod 406, a transverse guide cylinder 407 is fixedly installed on the surface of the rotating cylinder 301, and a vertical guide cylinder 408 is fixedly installed on the surface of the connecting rod 304. The wiping soft rope 201 passes through the matching gap between the active transmission wheel 404 and the driven transmission wheel 405, the guide port on the guide rod 406, the transverse guide cylinder 407 and the vertical guide cylinder 408 in sequence.

[0024] In practical application, when the embodiment of the present invention is revolved through the driving mechanism 5, as shown in FIG. Figure 7 and Figure 8 As shown, at this time, the follower gear 401 is driven to revolve, and the follower gear 401 is driven to rotate by the meshing action of the gear ring. The rotation of the follower gear 401 drives the active transmission wheel 404 to rotate through the transmission action of the bevel gear set 402, as shown in FIG. Figure 3 As shown, from Figure 3 From the front view direction, the active transmission wheel 404 rotates counterclockwise, thereby driving the wiping soft rope 201 to rotate clockwise through the cooperation with the driven transmission wheel 405, and at the same time, the guiding effect of the guide rod 406 allows the wiping soft rope 201 to absorb the disinfectant in the disinfection mechanism 6, and at the same time, the extrusion effect of the active transmission wheel 404 and the driven transmission wheel 405 squeezes out the excess disinfectant and recovers it to the disinfection mechanism 6, so as to fully recover the disinfectant. Figure 5 and Figure 6 As shown, the expansion effect of the wiping soft rope 201 is maximized through the guiding and limiting effects of the horizontal guide cylinder 407 and the vertical guide cylinder 408, so that the disinfection and wiping of the pipeline is more sufficient through contour contact, thereby increasing the efficiency of disinfection.

[0025] like Figure 4As shown, as another preferred embodiment of the present invention, the driving mechanism 5 includes a driving motor 501 fixedly mounted on the lifting mechanism 7, the output end of the driving motor 501 passes through the lifting mechanism 7 and is rotatably connected to the lifting mechanism 7, the output end of the driving motor 501 is fixedly mounted with a driving bevel gear 502, the driving bevel gear 502 is meshed with a driven bevel gear disc 503, a T-shaped cylinder 302 is coaxially fixedly mounted on the surface of the driven bevel gear disc 503, and the driven bevel gear disc 503 is rotatably connected to the lifting mechanism 7.

[0026] In practical application, the embodiment of the present invention is as follows: Figure 4 As shown, when the wiping soft rope 201 is driven to move to the entrance of the pipeline by the lifting mechanism 7, the driving motor 501 starts to move. The operation of the driving motor 501 drives the driven bevel gear disc 503 to rotate through the meshing action of the bevel gear disc, and then drives the T-shaped cylinder 302 to rotate, thereby driving the wiping soft rope 201 to revolve and rotate through the revolution mechanism 3 and the follower mechanism 4.

[0027] like Figure 3 As shown, as another preferred embodiment of the present invention, the disinfection mechanism 6 includes a disinfection cylinder 601 fixed on the lifting mechanism 7, and a shielding circular plate 602 is fixedly installed on the surface of the disinfection cylinder 601.

[0028] In actual application of the embodiment of the present invention, when the wiping soft rope 201 rotates, Figure 3 As shown, from Figure 3 When viewed from the front direction, as the wiping cord 201 rotates clockwise, the wiping cord 201 absorbs the disinfectant in the disinfection cylinder 601 under the guidance of the guide rod 406. It should be noted that since the wiping cord 201 rotates while also revolving, the disinfectant in the disinfection cylinder 601 is stirred. The shielding circular plate 602 is provided to avoid splashing of the disinfectant, thereby increasing the stability of the device and achieving the purpose of automatically absorbing the disinfectant.

[0029] like Figure 7As shown, as another preferred embodiment of the present invention, the lifting mechanism 7 includes a lifting hydraulic cylinder 701 fixedly mounted on the fixed plate 102, the output end of the lifting hydraulic cylinder 701 passes through the fixed plate 102 and is slidably connected to the fixed plate 102, the output end of the lifting hydraulic cylinder 701 is fixedly mounted with a multi-section telescopic cylinder 702, the surface of the multi-section telescopic cylinder 702 is fixedly mounted with a main movable plate 703, the surface of the main movable plate 703 is fixedly mounted with a supporting circular plate 704, the surface of the main movable plate 703 is fixedly mounted with a driving motor 501, the output end of the driving motor 501 passes through the main movable plate 703 and is rotatably connected to the main movable plate 703, the driven bevel gear plate 503 is rotatably connected to the surface of the main movable plate 703, the surface of the supporting circular plate 704 is fixedly mounted with a disinfection cylinder 601, and the surface of the main movable plate 703 is fixedly mounted with a fixed gear ring 403.

[0030] In actual application of the embodiment of the present invention, when performing a pipeline disinfection operation, the device is placed directly below the pipeline, such as Figure 7 As shown, the lifting hydraulic cylinder 701 starts to move. The operation of the lifting hydraulic cylinder 701 drives the multi-section telescopic cylinder 702 to extend vertically, thereby driving the main movable plate 703 to move upward, thereby driving the wiping soft rope 201 to move upward, and coordinating with the rotation and revolution of the wiping soft rope 201 to fully disinfect and sterilize the inner wall and the bending part of the pipeline.

[0031] like Figure 1 As shown, as another preferred embodiment of the present invention, the device further includes an airflow mechanism 8, and the airflow mechanism 8 includes a plurality of rotating blades 801 fixedly mounted on the surface of the rotating cylinder 301.

[0032] In actual application of the embodiment of the present invention, when the rotating cylinder 301 rotates, the rotating fan blades 801 are driven to rotate synchronously. The movement of the rotating fan blades 801 accelerates the movement of the airflow in the pipeline, thereby quickly evaporating the residual disinfectant wiped on the inner wall of the pipeline, preventing the odor of the disinfectant from entering the laboratory.
