Description

Technical Field

[0001] The present invention relates to the technical field of disinfection devices, and in particular to a multifunctional disinfection device for square cabin hospitals. Background Art

[0002] As a medical facility that can flexibly respond to public health incidents, Fangcang shelter hospitals are widely used in epidemic prevention and control and emergency treatment due to their rapid deployment, high space utilization, and flexible adjustment of functional zoning. However, Fangcang shelter hospitals are prone to become high-risk areas for pathogen transmission due to their relatively closed space, high mobility of personnel, and complex environment. Therefore, it is particularly important to carry out timely and effective disinfection of Fangcang shelter hospitals.

[0003] Chinese patent (Announcement No.: CN114712540A), the scheme specifically includes a shell, a base is installed at the bottom of the shell, a protective shell is connected to the upper end of the shell, a rotating cross support mechanism is connected to the front side of the protective shell, and two spraying mechanisms are connected to the outer ends of the support mechanism. The spraying mechanism and the support mechanism are supported by the protective shell, so that the support mechanism drives the spraying mechanism to slide and rotate on the sliding frame, changing the spacing and placement angle between the first sprayer and the second sprayer, facilitating the adjustment of the disinfection position and disinfection angle of the first sprayer and the second sprayer, increasing the comprehensiveness of the disinfection of the device, and facilitating the use of the device, and the first sprayer and the second sprayer are connected to the liquid storage tank through an infusion pump, and the large-capacity disinfectant is filled and stored through the liquid storage tank, which is convenient for increasing the working efficiency of the device during disinfection.

[0004] The disinfection device in the above patent can improve the disinfection efficiency when used. However, when used in a square cabin hospital where beds are placed, since the area under the beds is usually a blind area for disinfection, traditional disinfection methods are difficult to effectively cover the area under the bed, resulting in the inability to completely remove pathogens at this location, thereby increasing the potential risk of infection in the environment. At the same time, during the operation of existing mobile disinfection equipment in multiple areas, its body inevitably contacts surfaces in different areas, which may carry pathogens and form secondary transmission media inside the square cabin hospital. If the disinfection equipment itself is not disinfected synchronously, the pathogens may spread back to the disinfected area as the equipment moves, further exacerbating the risk of cross-infection. Therefore, a multifunctional disinfection device for square cabin hospitals is proposed. Summary of the invention

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 10 The present invention provides a technical solution: a multifunctional disinfection device for a square cabin hospital, comprising a vehicle body 1 and a directional nozzle 11 and a disinfection box arranged thereon, the vehicle body 1 is provided with a three-way pipe 43 for connecting the directional nozzle 11 and the disinfection box, the three-way pipe 43 is provided with a three-way valve for controlling the flow direction of the disinfectant, and the vehicle body 1 is provided with a multiple disinfection structure for gradient disinfection at different levels in the square cabin hospital;

[0043] The multiple disinfection structure includes a central mounting plate 2 fixedly connected to the vehicle body 1, a directional nozzle 11 is arranged above the central mounting plate 2, and a swing assembly is provided on the central mounting plate 2 to drive the directional nozzle 11 to perform multi-angle disinfection on the air of the cabin hospital;

[0044] The vehicle body 1 is fixedly connected with a circular step seat 23, on which a spray-blocking assembly for disinfecting the vehicle body 1 itself is arranged, the spray-blocking assembly comprising a plurality of groups of V-shaped directional rods 29 freely rotating in the horizontal direction, and a lateral spray head 30 in gas communication with the liquid outlet end of the three-way pipe 43 is fixedly connected to the V-shaped directional rods 29;

[0045] A bottom nozzle 40 for performing disinfection operations under the beds in the cabin hospital is provided below the circular step seat 23. The bottom nozzle 40 is gas-connected with the side nozzle 30, and a side extension component is provided on the vehicle body 1 to drive the bottom nozzle 40 to move freely in the horizontal direction.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, when performing disinfection operations on the cabin hospital, the vehicle body 1 is moved into the cabin. In the initial state, under the action of the three-way valve, the disinfection box and the directional nozzle 11 are connected, and the swing assembly is used to adjust the vertical direction of the directional nozzle 11, that is, the horizontal angle of the directional nozzle 11 is repeatedly changed, and the direction of the directional nozzle 11 can be adjusted synchronously under the drive of the swing assembly, so as to achieve disinfection operations with the vehicle body 1 as the center to the periphery, thereby maximizing the coverage capacity of the device and improving the uniformity of disinfection.

[0047] At the same time, the flow direction of the disinfectant is changed by the three-way valve so that the disinfectant flows to the side nozzle 30 and the bottom nozzle 40. Driven by the side extension assembly, the bottom nozzle 40 can be driven away from the vehicle body 1 in the horizontal direction, so that the bottom nozzle 40 is located under the bed, and the disinfectant is sprayed to the bottom of the bed through the bottom nozzle 40, thereby realizing the disinfection process of the bottom of the bed.

[0048] Among them, the air in the square cabin hospital may be full of germs, viruses and bacteria, especially in a closed environment. By disinfecting the air first, the pollution sources in the air can be effectively reduced and the risk of cross-infection caused by air transmission can be reduced. After the air is disinfected, the bottom of the bed is disinfected to ensure that the environmental conditions for the disinfection operation are cleaner, thereby improving the effectiveness of subsequent disinfection work.

[0049] Moreover, driven by the swing assembly, multiple groups of V-shaped directional rods 29 can be driven to rotate in the horizontal direction, and the V-shaped directional rods 29 are facing the vehicle body 1 in the initial state. When the V-shaped directional rods 29 rotate, they can swing back and forth in the vertical direction at a certain angle, thereby changing the direction of the lateral nozzle 30, so that the disinfectant sprayed from the lateral nozzle 30 can disinfect the vehicle body 1 itself.

[0050] It should be noted that, in actual use, the vehicle body 1 will come into contact with various areas during the movement and operation in multiple cabins, and may easily become a carrier of pathogens. If the vehicle body 1 itself is not disinfected, the pathogens may spread back into the hospital environment through the movement of the vehicle body 1. By adding the disinfection of the vehicle body 1 itself to the disinfection sequence, this secondary contamination can be avoided, and by changing the direction of the lateral nozzle 30, the comprehensiveness of the disinfection of the vehicle body 1 can be ensured.

[0051] In one of the more preferred embodiments, the swing assembly includes a central column 5 that rotates on a fixed axis on a vehicle body 1, a hollow cylinder 3 is provided on the outer periphery of the central column 5, a vertical slide groove is provided on the central mounting plate 2 for the hollow cylinder 3 to be slidably connected in a vertical direction, a transverse axis 6 is provided on the top of the central column 5 that rotates on a fixed axis, and a special-shaped rod 10 and a turning column 7 are fixedly connected at both ends of the transverse axis 6;

[0052] The directional nozzle 11 is fixedly connected to the special-shaped rod 10, the end of the turning column 7 away from the transverse axis 6 is fixedly connected to the positioning ball 8, the upper part of the hollow cylinder 3 is fixedly connected to the annular seat 4, and the annular seat 4 is provided with an annular positioning groove 9 for the positioning ball 8 to be slidably connected;

[0053] The central mounting plate 2 is provided with a longitudinal swing assembly for adjusting the horizontal pitch angles of the shaped rod 10 and the directional nozzle 11.

[0054] like Figure 1-Figure 3 As shown, the central column 5 is driven by a motor fixedly connected to the vehicle body 1 to rotate in the horizontal direction, thereby driving the transverse axis 6 arranged thereon and the special-shaped rod 10 and the turning column 7 at the end of the transverse axis 6 to rotate horizontally synchronously, wherein the directional nozzle 11 is arranged on the special-shaped rod 10, so that the horizontal direction of the directional nozzle 11 can be changed through the rotation process of the central column 5.

[0055] At the same time, the positioning sphere 8 fixedly arranged at the end of the turning column 7 is slidably connected to the annular seat 4 through the annular positioning groove 9. Therefore, no matter what the pitch angle of the directional nozzle 11 is, the central column 5 can drive the turning column 7 and the positioning sphere 8 to slide in the annular positioning groove 9 when the transverse axis 6 rotates, and when the horizontal height of the annular seat 4 changes, the transverse axis 6 can be driven to rotate a certain angle in the vertical direction by changing the height of the positioning sphere 8, thereby changing the pitch angle of the special-shaped rod 10 and the directional nozzle 11.

[0056] Based on the embodiment of the swing assembly, the longitudinal swing assembly includes a swing cylinder 15 that rotates on a fixed axis on the central mounting plate 2, a fork frame 12 is fixedly connected to the outer peripheral surface of the swing cylinder 15, and a limit pin 13 is fixedly connected to the side of the fork frame 12 facing the hollow cylinder 3;

[0057] Two groups of limiting rings 14 are fixedly connected to the hollow cylinder 3 , the limiting pin 13 is located between the two groups of limiting rings 14 , and the limiting pin 13 is in sliding contact with the opposite surfaces of the two groups of limiting rings 14 .

[0058] The longitudinal swing assembly also includes a connecting rod 16 that rotates on the central mounting plate 2 and is transmission-connected to the central column 5. A freely swinging swing rod 18 is provided on the connecting rod 16. The swing rod 18 and the swing tube 15 are coaxially fixed.

[0059] The connecting rod 16 is fixedly connected with a positioning pin 17 , and the swing rod 18 is provided with a positioning groove 19 for the positioning pin 17 to be slidably connected.

[0060] like Figure 2-Figure 4 As shown, the connecting rod 16 is transmission-connected to the center column 5. When the center column 5 rotates, the connecting rod 16 can be driven to rotate in the vertical direction. The positioning pin 17 arranged at the end of the connecting rod 16 is slidingly connected to the rocker arm 18 through the positioning groove 19. Therefore, when the connecting rod 16 rotates freely, the rocker arm 18 can be driven to drive the rocker tube 15 to reciprocate in the vertical direction in a fan-shaped trajectory.

[0061] Among them, a fork frame 12 is fixedly connected to the swing cylinder 15, and a limit pin 13 fixedly arranged at the end of the fork frame 12 abuts against two groups of limit rings 14. Therefore, when the swing cylinder 15 rotates, the fork frame 12 arranged thereon rotates synchronously, and the horizontal height of the end limit pin 13 is changed, and the horizontal height of the limit ring 14 and the hollow cylinder 3 is changed by the limit pin 13. In addition, the hollow cylinder 3 is fixedly connected to the annular seat 4. When the annular seat 4 moves in the vertical direction following the hollow cylinder 3, it can drive the transverse axis 6 and the directional nozzle 11 to deflect by changing the height of the positioning sphere 8, thereby changing the pitch angle of the directional nozzle 11.

[0062] Among them, the directional nozzle 11 is driven to swing back and forth in the vertical direction, and the horizontal direction of the directional nozzle 11 is changed under the drive of the swing assembly, thereby further increasing the disinfection area in the cabin to ensure the comprehensiveness of the disinfection process and improve the disinfection efficiency of the cabin hospital.

[0063] On the basis of the embodiment of the pitch assembly, the side extension assembly comprises a bottom gear 34 which is rotated on the vehicle body 1 and is transmission-connected to the center column 5, and the bottom gear 34 is provided with two sets of transverse extension racks 35 which move synchronously toward or away from each other in the horizontal direction, and the two sets of transverse extension racks 35 are meshedly connected with the bottom gear 34, and a transverse slide groove for the transverse extension racks 35 to slide horizontally is provided on the vehicle body 1;

[0064] The transversely extending rack 35 slides through the vehicle body 1 and is fixedly connected to an end plate 39. A rectangular horizontal groove 101 is provided at a position of the vehicle body 1 corresponding to the end plate 39. A side of the end plate 39 away from the vehicle body 1 is fixedly connected to the bottom nozzle 40.

[0065] The transversely extending rack 35 is provided with a blocking component for limiting the horizontal movement distance of the transversely extending rack 35 .

[0066] like Figure 1 , Figure 8 and Fig.10As shown, the bottom gear 34 is connected to the center column 5 by transmission, and when the center column 5 rotates, the bottom gear 34 is driven to rotate synchronously, wherein the bottom gear 34 is meshingly connected with two sets of transverse racks 35 arranged opposite to each other. Therefore, when the bottom gear 34 rotates, the two sets of transverse racks 35 drive the end plate 39 at the end to move away from the vehicle body 1 or approach the vehicle body 1 synchronously.

[0067] Among them, when the air in the other cabin is disinfected, the two groups of annular positioning grooves 9 are away from the vehicle body 1, and when in use, the vehicle body 1 can be moved between the two groups of beds. Through the horizontal movement of the annular positioning grooves 9, the bottom nozzles 40 arranged at the ends of the annular positioning grooves 9 are located below the two groups of beds. At this time, the flow direction of the disinfectant is adjusted by the three-way valve. Under the pumping equipment, the disinfectant can be sprayed to the bottom of the bed through the bottom nozzles 40, and then the blind area of ​​the bottom of the bed is disinfected to ensure the thoroughness of the disinfection of the space in the other cabin.

[0068] Based on the embodiment of the side extension assembly, the blocking assembly includes a tooth 36 arranged at the end of the transverse extension rack 35, a side ear block is fixedly connected to the tooth 36, a guide column 37 is slidably penetrated through the side ear block, and the end of the guide column 37 away from the tooth 36 is fixedly connected to the transverse extension rack 35;

[0069] The outer circumference of the guide column 37 is sleeved with a return spring 38 , and the two ends of the return spring 38 are fixedly connected to the side ear seat and the transversely extending rack 35 respectively.

[0070] like Figure 1 , Figure 8 and Fig. 9 As shown, the bottom gear 34 is connected to the center column 5 by transmission, and the center column 5 drives the swing assembly to operate. Therefore, when the swing assembly is operating, the rotation process of the bottom gear 34 can drive the two sets of transverse racks 35 to move away from the vehicle body 1, and after the end plate 39 is at the end of the horizontal stroke, the disinfection box can be connected with the bottom nozzle 40 under the action of the three-way pipe 43, thereby performing disinfection operations on the area under the bed.

[0071] It should be noted that in actual use, the spray-blocking assembly and the side-extending assembly operate synchronously. In order to ensure that there is no interference between the two during operation, teeth 36 are provided at the end of the transverse rack 35. When the transverse rack 35 is in the terminal position, the distance between it and the vehicle body 1 reaches a maximum value. At this time, the bottom gear 34 is engaged with the teeth 36, and the continued rotation of the center column 5 will only drive the teeth 36 to fluctuate repeatedly on the transverse rack 35, and will no longer drive the horizontal position of the bottom nozzle 40 to change, and can ensure that the rotation process of the bottom gear 34 is not hindered.

[0072] Furthermore, the spray blocking assembly further comprises a central gear 20 fixedly sleeved on the central column 5, the central gear 20 is meshedly connected with a side gear 21, the side gear 21 is fixedly rotated on the central mounting plate 2, the side gear 21 is meshedly connected with an inner gear ring 22, and an incomplete circular groove for sliding connection of the inner gear ring 22 is provided on the central mounting plate 2;

[0073] A plurality of groups of the V-shaped directional rods 29 are arranged in a circular array on the inner gear ring 22 , and a fixed spray assembly for adjusting the direction of the lateral spray head 30 is provided on the circular step seat 23 .

[0074] The fixed spray assembly includes a plurality of axial rods 24 fixedly connected to the inner gear ring 22, a transverse rod 25 is provided on the axial rod 24, and a groove body 1 for the transverse rod 25 to slide and connect in the horizontal direction is opened on the axial rod 24, an axial pin 26 is fixedly connected to the transverse rod 25, and a V-shaped ring groove 27 for the axial pin 26 to slide and connect is opened on the circular step seat 23;

[0075] The end of the transverse rod 25 away from the axial rod 24 is fixedly rotated with a yield rod 28, and the end of the yield rod 28 away from the transverse rod 25 is fixedly rotated on the end of the V-shaped directional rod 29. A homonymous seat 31 is provided on the circular step seat 23, and the middle part of the V-shaped directional rod 29 is fixedly rotated on the homonymous seat 31. A homonymous pin 32 is fixedly connected to the homonymous seat 31, and a homonymous groove 33 for sliding connection of the homonymous pin 32 is opened on the circular step seat 23.

[0076] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, when the center column 5 rotates, it can drive the center gear 20 connected to it to rotate synchronously, and the center gear 20 is meshed with the side gear 21. When the side gear 21 rotates with the center gear 20, it can drive the inner ring gear 22 to rotate in the horizontal direction, and the incomplete circular groove opened on the center mounting plate 2 can ensure the stability of the inner ring gear 22 during the rotation process.

[0077] At the same time, the axial rod 24 fixed on the inner gear ring 22 drives the transverse rod 25 to rotate synchronously, and then drives the V-shaped directional rod 29 and the lateral nozzle 30 fixed thereon to rotate around the center of the circular step seat 23 through the transverse rod 25, thereby disinfecting the viruses attached to the outer surface of the vehicle body 1.

[0078] Among them, the axial pin 26 arranged on the transverse rod 25 is slidably connected to the circular step seat 23 through a V-shaped ring groove 27. When the transverse rod 25 rotates, the horizontal position of the transverse rod 25 can be changed through the axial pin 26, and the end of the transverse rod 25 is rotatably connected to the V-shaped directional rod 29 through the yield rod 28. Since the distance between the same position seat 31 and the center of the circular step seat 23 remains unchanged, when the horizontal position of the transverse rod 25 changes, the V-shaped directional rod 29 can be deflected on the same position seat 31, thereby changing the direction of the lateral nozzle 30, so that the lateral nozzle 30 can spray disinfectant on different positions of the outer surface of the vehicle body 1, thereby avoiding the risk of cross infection when the vehicle body 1 is rolled over multiple cabins.

[0079] Based on the embodiment of the anti-spray assembly, the three-way valve includes an integrally formed valve stem, and a valve position gear 42 is coaxially fixed on the valve stem. The valve position gear 42 rotates on the vehicle body 1 on a fixed axis, and a drive rack 41 meshing with the valve position gear 42 is fixedly connected to the transverse rack 35.

[0080] like Figure 8 As shown, when the transverse rack 35 gradually moves horizontally away from the vehicle body 1, the driving rack 41 can be driven to move toward the valve position gear 42 and make the two mesh. Subsequently, as the transverse rack 35 moves, the valve position gear 42 and the valve stem coaxially fixed thereon can be driven to rotate, thereby changing the flow direction of the disinfectant, wherein the inlet end of the three-way pipe 43 is connected with the disinfection box through a pumping setting, one group of outlet ends of the three-way pipe 43 is connected with the directional nozzle 11, and the other group of outlet ends of the three-way pipe 43 is connected with the lateral nozzle 30, and the gas between the lateral nozzle 30 and the bottom nozzle 40 is connected.

[0081] Therefore, through the rotation process of the valve position gear 42, the flow direction of the disinfectant can be changed. When the disinfectant flows to the directional nozzle 11, the air in the cabin can be disinfected through the swing assembly.
