Description

Technical Field

[0001] The present invention relates to the field of disinfection equipment, and in particular to an intelligent ultraviolet cabin disinfection device. Background Art

[0002] With the global outbreak of the novel coronavirus in December 2019, more and more cities have entered a state of emergency. The spread between people has made people inadvertently spread and carry the virus. As railways and aviation occupy an important position in people's travel, the virus will also spread around the world with people traveling by railways and aviation. The risk of being invaded by the virus in a confined space is greatly increased. According to relevant data, the probability of passengers and crew members being infected is more than 4 times that of ordinary employees. Infectious bacteria and viruses can survive on untreated surfaces for more than 7 days.

[0003] UVC lamps are trusted by hospitals. They can quickly kill bacteria on exposed surfaces and are a very efficient and convenient way to disinfect. Unfortunately, there is no use of UVC lamps in domestic railways and civil aviation. The current disinfection measures are still traditional spraying of disinfectants, which is time-consuming and inefficient. There is an irritating smell after spraying, and it cannot be operated immediately, and the effect is not very satisfactory. Summary of the invention

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Combination Figures 1 to 5 As shown, an intelligent ultraviolet cabin disinfection device includes a movable body 1, which adopts a frame structure and is designed according to the appearance of a push dining car for railways, high-speed railways or civil aviation. A lifting frame 2 is provided in the middle of the body 1, and the lifting frame 2 is connected to a first driving mechanism for driving the lifting frame 2 to rise or fall. A foldable wing frame 3 is provided on the left and right sides of the lifting frame 2 respectively, and the foldable wing frames 3 are connected to a second driving mechanism for driving the foldable wing frames 3 to be laterally unfolded or folded. A plurality of ultraviolet lamp tubes 4 are installed on the body 1, the lifting frame 2 and the foldable wing frames 3; the ultraviolet lamp tubes 4 are UVC ultraviolet lamps. In the specific arrangement, a total of six ultraviolet lamp tubes 4 are installed on the left and right sides of the body, one is installed on the left and right sides of the top of the lifting frame 2, and nine are installed on each foldable wing frame 3, thereby realizing all-round irradiation and disinfection of the surfaces of objects such as plastics, metals, leathers and fabrics in the cabin.

[0029] A controller 5 is also provided on the vehicle body 1, and the controller 5 is connected to and controls the first driving mechanism, the second driving mechanism and the ultraviolet lamp 4. The controller 5 is specifically composed of a control button and a STC90C514RD single chip microcomputer, and the signal output end of the control button is connected to the signal input end of the single chip microcomputer, so as to realize the control of the device through the control button.

[0030] The first driving mechanism includes an electric push rod 6, a sprocket 7 and a chain 8. The electric push rod 6 is arranged at the base of the vehicle body 1, and the output end of the electric push rod 6 is vertically upward. The sprocket 7 is installed at the top of the electric push rod 6. One end of the chain 8 is connected to the base of the vehicle body 1, and the other end of the chain 8 is connected to the bottom side of the lifting frame 2 after bypassing the sprocket 7. The signal output end of the controller 5 is connected to the control end of the electric push rod 6. When the controller 5 controls the electric push rod 6 to extend, the lifting frame 2 rises at twice the speed and displacement. When the controller 5 controls the electric push rod 6 to shorten, the lifting frame 2 falls naturally under the action of gravity. The electric push rod 6 has upper and lower limit functions, which can limit the rising and falling positions of the lifting frame 2.

[0031] In addition, the vehicle body 1 is provided with a supporting guide angle iron 9, and the lifting frame 2 moves up and down along the supporting guide angle iron 9, thereby increasing the stability of lifting.

[0032] Specifically, the foldable wing frame 3 is a scissor-type multi-link structure, a sliding rod 10 is vertically provided on the lifting frame 2, a sliding sleeve 11 is provided on one of the connecting rods at the inner end of the foldable wing frame 3, and the connecting rod is movably connected to the sliding rod 10 through the sliding sleeve 11, and a hinge 12 is provided on the other connecting rod, which is movably connected to the lifting frame 2 through the hinge 12.

[0033] The second driving mechanism includes a micro motor 13, a drum 14, a fixed pulley 15 and a traction rope 16. The micro motor 13 is installed on the lifting frame 2, the drum 14 is installed on the output shaft of the micro motor 13, the fixed pulley 15 is suspended on the top of the lifting frame 2, the traction rope 16 is wound on the drum 14, and one end of the traction rope 16 is directly connected to the sliding sleeve 11, and the other end is connected to the sliding sleeve 11 after bypassing the fixed pulley 15; the signal output end of the controller 5 is connected to the control end of the micro motor 13, when the controller 5 controls the micro motor 13 to rotate forward, the sliding sleeve 11 moves downward along the sliding rod 10, and the foldable wing frame 3 is laterally unfolded, when the controller 5 controls the micro motor 13 to reverse, the sliding sleeve 11 moves upward along the sliding rod 10, and the foldable wing frame 3 is folded and retracted.

[0034] In particular, a first limit switch 17 is provided at the bottom of the sliding rod 10, and a second limit switch 18 is provided at the top of the sliding rod 10. The signal output ends of the first limit switch 17 and the second limit switch 18 are connected to the signal input end of the controller 5, and the controller 5 is connected to a timer 19; when the controller 5 controls the micro motor 13 to rotate forward so that the sliding sleeve 11 moves downward to the first limit switch 17, the controller 5 controls the ultraviolet lamp 4 on the foldable wing frame 3 to turn on, and starts the timer 19 to start timing. After reaching a predetermined time, the controller 5 controls the ultraviolet lamp 4 on the foldable wing frame 3 to turn off, and controls the micro motor 13 to reverse so that the sliding sleeve 11 moves upward to the second limit switch 18 and stops.

[0035] When performing disinfection work, the device can be fully extended and raised to cover every row of seats and luggage rack area, and can also be extended to the bathroom on one side for disinfection. The specific operation process is as follows:

[0036] Taking manual operation as an example, by pressing the corresponding control button, the controller 5 controls the electric push rod 6 to extend, so that the lifting frame 2 rises to the working plane, turns on the car body 1 and the ultraviolet lamp tube 4 on the lifting frame 2, and then pushes the car body 1 to move. When the car body 1 moves to the side of the seat of the train passenger car, press the corresponding button. At this time, the micro motor 13 works to drive the sliding sleeve 11 to move along the sliding rod 10, and the foldable wing frame 3 gradually unfolds. When the sliding sleeve 11 moves to the first limit switch position, the switch is triggered. At this time, the foldable wing frame 3 is fully unfolded laterally, and the controller 5 will control the ultraviolet lamp tube 4 on the foldable wing frame 3 to turn on. Each ultraviolet lamp tube 4 will carry out disinfection operations at a specific angle. The ultraviolet lamp tubes 4 irradiate together to cover the disinfection area at all angles. At the same time, the timer 19 is started to start timing. After reaching a predetermined time (generally 6-8s), the micro motor 13 is controlled to reverse and move the sliding sleeve 11 upward, and the ultraviolet lamp tube 4 is gradually folded. While folding, the ultraviolet lamp tube 4 on the foldable wing frame 3 is controlled to be turned off to prevent the operator from misoperating and causing unnecessary ultraviolet radiation, while saving battery energy. When the sliding sleeve 11 moves upward to the second limit switch 18, it stops. At this time, the foldable wing frame 3 is completely folded and folded, thereby completing the disinfection of one seat. After returning to the original state, the car body 1 can continue to move forward in the aisle of the passenger car until it reaches the next disinfection position, and repeat the above process. According to calculations, within 3 minutes, a Boeing 737 cabin or a high-speed rail interior compartment can be disinfected to kill 99% of harmful bacteria, with high disinfection efficiency and good effect.

[0037] In addition, the foldable wing frames 3 and the ultraviolet lamp tubes 4 on both sides are controlled separately. The ultraviolet lamp tubes 4 on one side can be turned on to disinfect the bathroom on one side. The foldable wing frames 3 can also be folded at the same time, and the ultraviolet lamp tubes 4 on the vehicle body 1 and the lifting frame 2 can be used to disinfect the kitchen area.

[0038] The bottom of the vehicle body 1 is provided with a wheel set 20 with a suspension function and a brake function and a remote control tractor 25. The wheel set 20 at the bottom needs not only a load-bearing wheel set but also a spring suspension function to ensure a stable movement ability when passing through an uneven carriage floor. During the disinfection work, the vehicle body 1 can be manually pushed for disinfection, or the movement of the vehicle body 1 can be electrically controlled by remote control.

[0039] When the device is idle, the train is running. When the vehicle is shaking, the vehicle body 1 must remain stationary at the designated position and avoid accidents such as rollover and overturning. The wheel set 20 of the vehicle body 1 must have a brake function to prevent the vehicle from moving autonomously. Considering the slender and tall structure of the vehicle body 1, a foldable support rod (not shown in the figure) can be added to the four sides of the vehicle body 1. When the device is idle, the support rod can ensure the stability of the vehicle body 1.

[0040] A rechargeable lithium battery 21 is provided on the base of the car body 1, and the device is powered by the lithium battery 21 or connected to an AC 110-220V wide voltage power supply. The weight of the lithium battery 21 itself also helps to provide a solid chassis stability for the tall and thin car body 1 to prevent accidents such as the car body 1 tipping over or overturning. A design similar to a vacuum cleaner cable shaft is installed at the bottom of the car body 1. When the car body 1 reaches the charging position, the operator can pull out the cable for charging, and the cable will automatically retract into the cable shaft after charging. Wireless charging equipment can be deployed at both ends of the train with wireless charging function, so that disinfection and charging can be carried out without going back.

[0041] Push rods 22 are installed on the front and rear sides of the vehicle body 1, and a protective cover 23 is provided at the upper position corresponding to the push rod 22. The protective cover 23 is made of transparent acrylic glass that is UV-proof. A warning light 24 is installed on the top of the vehicle body 1, and the control end of the warning light 24 is connected to the signal output end of the controller 5. During the disinfection process, the operator is always at the rear of the vehicle body 1, and uses both hands to push the push rod 22 on the vehicle body 1 to control the forward movement of the vehicle body 1. At the same time, long-term exposure to ultraviolet rays will have adverse health effects on the human body. The protective cover 23 can achieve the greatest protection of personnel without blocking the operator's sight. At the same time, the warning light 24 on the top of the cart can light up when the ultraviolet lamp 4 is turned on to warn other personnel to stay away from the disinfection site.

[0042] Preferably, the controller 5 is provided with a human-machine interface, and relevant operation information can be input on the device, and a disinfection record report can be printed through a wireless or wired connection to a printer, or it can be transmitted to a corresponding storage device via USB or wirelessly for centralized printing.

[0043] 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.
