On the one hand, the arc-shaped hanging rail 501 can be slid on the top of the intensive care unit 1, so that the ultraviolet disinfection range below the arc-shaped hanging rail 501 is larger. On the other hand, it plays a guiding and limiting role on the arc-shaped hanging rail 501 to prevent deviation. An arc-shaped guide groove 502 is provided on the inner side of the arc-shaped hanging rail 501, and the lower side of the arc-shaped guide groove 502 runs through the arc-shaped hanging rail 501. The arc-shaped hanging rail 501 adopts a "U"-shaped structure, which is convenient for disinfecting the outside and the middle of the bed and improving the disinfection range. The inner wall of the arc-shaped guide groove 502 is fixedly provided with a second rack 503, and one end of the arc-shaped hanging rail 501 is fixedly connected to a fan-shaped hanging rail 506. The fan-shaped hanging rail 506 adopts a 1 / 4 arc structure, and a fan-shaped guide groove 507 connected to the arc-shaped guide groove 502 is provided on the inner side of the fan-shaped hanging rail 506. A transition rack 508 cooperating with the second rack 503 is fixedly provided on the inner side of the fan-shaped guide groove 507.

[0031] like Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, a linear hanging rail mechanism 3 is provided at the top of the intensive care unit 1, and the linear hanging rail mechanism 3 includes a linear hanging rail 301 fixedly arranged at the top of the intensive care unit 1, and the linear hanging rail 301 is installed on the outer side of the partition 2, that is, the linear hanging rail 301 is arranged above the aisle area of ​​the intensive care unit 1, and a linear guide groove 302 is opened on the inner side of the linear hanging rail 301, and the lower side of the linear guide groove 302 passes through the lower side of the linear hanging rail 301, and the width of the lower side of the linear guide groove 302 is smaller than the width of the upper side of the linear guide groove 302, so that the lower end of the linear hanging rail 301 can be provided with a protrusion inwardly, and a first rack 303 is fixedly provided on the inner side of the linear guide groove 302.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 7As shown, a plurality of rail block reset mechanisms 4 are slidably arranged on the linear hanging rail mechanism 3, and the rail block reset mechanism 4 includes a splicing rail block 405 which is slidably arranged on the top of the intensive care unit 1 and is slidably connected with the linear hanging rail 301. The linear hanging rail 301 adopts a multi-section structure, and the splicing rail block 405 is arranged between two adjacent sections of the linear hanging rail 301, and is used to connect the two adjacent sections of the linear hanging rail 301. A splicing guide groove 407 which is connected and matched with the linear guide groove 302 is opened on the inner side of the splicing rail block 405, and a splicing rack 406 which is matched with the first rack 303 is fixedly arranged on the inner side of the splicing guide groove 407. A reset slide rod 404 is fixedly arranged on one side of the splicing rail block 405, and a reset cylinder 402 is slidably sleeved on one end of the reset slide rod 404, and a reset cylinder 402 is fixedly arranged on the inner side of the reset cylinder 402. A reset spring 403 is fixedly connected to one end of the reset slide bar 404, and a fixed plate 401 fixedly connected to the top of the intensive care unit 1 is fixedly provided on one side of the reset cylinder 402. When the splicing hanging rail block 405 is connected with both sides of the linear hanging rail 301, the reset spring 403 pushes one end of the reset slide bar 404 and completely slides out of the reset cylinder 402, so that the two adjacent linear hanging rails 301 are connected together. When the splicing hanging rail block 405 is separated from the linear hanging rail 301 by external force, the reset slide bar 404 will slide into the interior of the reset cylinder 402, thereby compressing the reset spring 403 inside the reset cylinder 402. When the external force disappears, the splicing hanging rail block 405 can be automatically reset by the reset spring 403, that is, the splicing hanging rail block 405 is automatically connected to the linear hanging rail 301.

When in use, the first servo motor 603 drives the first screw rod 602 to rotate, drives the push block 604 to slide on the inner side of the guide sleeve 601, and the push block 604 The push rod 605 is driven to slide, and the arc-shaped hanging rail 501 at the other end of the push rod 605 is driven to slide on the top surface of the intensive care unit 1 in the direction of the straight hanging rail 301, thereby squeezing the spliced ​​hanging rail block 405, so that the spliced ​​hanging rail block 405 is pushed out from the straight hanging rail 301. During the pushing process, the spliced ​​hanging rail block 405 drives the reset slide bar 404 to slide into the interior of the reset cylinder 402, thereby compressing the reset spring 403 inside the reset cylinder 402. When the horizontal port at one end of the fan-shaped hanging rail 506 is connected with the straight hanging rail 301, the first servo motor 603 stops working, so that one end of the fan-shaped hanging rail 505 can be connected with the straight hanging rail 301, so as to facilitate moving the ultraviolet lamp tube 803 on the straight hanging rail 301 to the arc-shaped hanging rail 501, so as to facilitate the fixed-point disinfection of the hospital bed.

[0034] Embodiment 2: Based on embodiment 1, further improvement is made in that Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6As shown, a suspension-driven lifting mechanism 10 is arranged on the linear hanging rail 301, and the suspension-driven lifting mechanism 10 includes a suspension cylinder 1001 slidably suspended below the linear hanging rail 301, and a limiting rubber block 1003 slidably clamped at the lower end opening of the linear guide groove 302 is fixedly arranged on the upper end of the suspension cylinder 1001, and the width of the limiting rubber block 1003 is consistent with the width of the lower end opening of the linear guide groove 302, and is used to limit the self-rotation of the suspension cylinder 1001, and a suspension plate 1005 slidably arranged on the inner surface of the lower side of the linear hanging rail 301 is fixedly arranged on the upper side of the limiting rubber block 1003, and the lower surface of the suspension plate 1005 abuts against the inner side of the protrusion at the lower end of the linear hanging rail 301, and is used to The suspension tube 1001 is suspended on the lower side of the linear hanging rail 301, and a second servo motor 1002 is fixedly arranged on the inner side of the upper end of the suspension tube 1001. The output end of the second servo motor 1002 rotates through the limiting rubber block 1003 and the suspension plate 1005 and is fixedly connected with a gear 1004 meshing with the first rack 303. When in use, the second servo motor 1002 drives the gear 1004 to rotate, so that the gear 1004 can be meshed with the first rack 303 on the inner side of the linear hanging rail 301, thereby driving the suspension tube 1001 to slide on the lower side of the linear hanging rail 301, so that the suspension tube 1001 moves to the fixed bed area 7 to perform fixed-point disinfection on the bed.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a third servo motor 1006 is fixedly provided on the inner side of the suspension tube 1001, and a second screw rod 1007 rotatably connected to the inner side of the suspension tube 1001 is fixedly provided on the output end of the third servo motor 1006, and a threaded sleeve 1008 slidably connected to the inner side of the suspension tube 1001 is threadedly sleeved on the second screw rod 1007, and a lifting rod 1009 slidingly penetrating the lower end of the suspension tube 1001 is fixedly provided on the lower side of the threaded sleeve 1008, and an ultraviolet disinfection mechanism 8 is fixedly provided on the lower end of the lifting rod 1009, and the ultraviolet disinfection mechanism 8 includes a base 801 fixedly provided on the lower end of the lifting rod 1009, a reflective tube 802 is fixedly provided on the inner side of the base 801, and the reflective tube 802 is slidably sleeved on the lower end of the suspension tube 1001, and a plurality of ultraviolet light-emitting diodes circumferentially arranged on the outer side of the reflective tube 802 are fixedly provided on the outer side of the base 801 The linear lamp tube 803 can improve the range of ultraviolet disinfection by circumferentially arranged multiple ultraviolet lamp tubes 803. The outer side of the reflective tube 802 is attached with a reflective film, which can reflect the ultraviolet rays irradiated by the ultraviolet lamp tube 803 onto the reflective tube 802, thereby improving the utilization rate of ultraviolet rays and further improving the ultraviolet disinfection effect. The bottom of the base 801 is installed with an ozone generator 9 by screws. When in use, the second screw rod 1007 is driven to rotate by the third servo motor 1006, so that the threaded sleeve 1008 can be lifted and lowered under the action of the second screw rod 1007, thereby driving the lifting rod 1009 on the lower side of the threaded sleeve 1008 to lift and lower, and then driving the base 801 at the lower end of the lifting rod 1009 to lift and lower, so that the multiple ultraviolet lamp tubes 803 outside the base 801 can be lifted and lowered, and the areas at different heights of the bed can be disinfected.

[0036] It should be noted that, when the ultraviolet disinfection robot for ICU fixed beds is in use, when it is necessary to disinfect a certain bed area 7, it is only necessary to slide the arc-shaped hanging rail 5 above the corresponding bed area 7. The specific steps are: the first servo motor 603 drives the first screw rod 602 to rotate, drives the push block 604 to slide on the inner side of the guide sleeve 601, and the push block 604 drives the push rod 605 to slide, drives the arc-shaped hanging rail 501 at the other end of the push rod 605 to slide on the top surface of the intensive care unit 1 in the direction of the linear hanging rail 301, and then squeezes the spliced ​​hanging rail block 405, so that the spliced ​​hanging rail block 405 is pushed out from the linear hanging rail 301. During the pushing process, the spliced ​​hanging rail block 405 drives the reset slide bar 404 to slide into the reset cylinder 402. The reset spring 403 inside the reset cylinder 402 is compressed. When the horizontal port at one end of the fan-shaped hanging rail 506 is connected to the linear hanging rail 301, the first servo motor 603 stops working, so that one end of the fan-shaped hanging rail 505 can be connected to the linear hanging rail 301, and then the second servo motor 1002 drives the gear 1004 to rotate, so that the gear 1004 can be meshed with the first rack 303 inside the linear hanging rail 301, thereby driving the suspension cylinder 1001 to slide on the lower side of the linear hanging rail 301. Since the fan-shaped hanging rail 506 is connected to the linear hanging rail 301, when the gear 1004 rotates to one side of the fan-shaped hanging rail 506, the gear 1004 will mesh with the transition rack 508 inside the fan-shaped hanging rail 506. The second servo motor 1002 then drives the gear 1004 to rotate, so that the gear 1004 engages with the second rack 503 on the inner side of the arc-shaped hanging rail 501, so that the suspension cylinder 1001 is transferred from the lower side of the fan-shaped hanging rail 506 to the lower side of the arc-shaped hanging rail 501, and the ultraviolet lamp 803 on the lower side of the suspension cylinder 1001 is transferred to the corresponding bed area 7, and then the third servo motor 1006 drives the second screw rod 1007 to rotate, so that the threaded sleeve 1008 can be lowered on the inner side of the suspension cylinder 1001, thereby driving the lifting rod 1009 on the lower side of the threaded sleeve 1008 to descend, thereby driving the lifting rod 1009 on the lower side of the threaded sleeve 1008 to descend, and then driving the lifting rod 1009 on the lower side of the threaded sleeve 1008 to descend. The base 801 at the lower end of 009 descends, so that the multiple ultraviolet lamps 803 on the outside of the base 801 descend, and the multiple ultraviolet lamps 803 suspended above can be lowered to the side of the bed to perform ultraviolet disinfection on the upper side of the bed, and when the base 801 descends, the ozone generator 9 at the bottom of the base 802 will descend to the bottom of the side of the bed, so that the bottom of the bed is disinfected with ozone, thereby making the upper and lower sides of the bed disinfected at the same time, thereby improving the disinfection efficiency, and the second servo motor 1002 drives the gear 1004 to rotate, so that the suspension tube 1001 moves along the linear hanging rail 301 and the spliced ​​hanging rail block 405 to the corresponding bed area 7, and then through the pushing mechanism 6 of the corresponding bed area 7,The arc-shaped hanging rail 501 corresponding to the bed area 7 can be connected to the straight hanging rail 301, so that the ultraviolet lamp 803 and the ozone generator 9 can be moved to the designated bed area 7 to achieve fixed-point disinfection.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
