This technology is not only effective against bacteria, but also can kill various pathogens such as viruses and parasites. At present, the research and application of ultraviolet disinfection technology have been further emphasized in fields such as hospitals, laboratories, and food processing.

[0003] Chinese Patent Publication No.: CN115978693A discloses a two-purpose vehicle for direct ultraviolet lamp irradiation and circulating air ultraviolet purification and disinfection, including a direct ultraviolet lamp irradiation device and a circulating air ultraviolet disinfection device; the direct ultraviolet lamp irradiation device includes a direct ultraviolet lamp irradiation auxiliary component, an ultraviolet lamp, a control box, and a trolley component; the circulating air ultraviolet disinfection device includes a circulating air component, an ultraviolet lamp, a lamp box, a control box, and a trolley component; the direct ultraviolet lamp irradiation auxiliary component includes a lamp box and a lamp arm; the circulating air component includes an air box, a filter screen, and two or more blowers; its characteristics are that the direct ultraviolet lamp irradiation device and the circulating air ultraviolet disinfection device share the same ultraviolet lamp. It can be seen that the two-purpose vehicle for direct ultraviolet lamp irradiation and circulating air ultraviolet purification and disinfection has problems such as the decrease in the stability of the ultraviolet lamp tube due to the increase in the center of gravity of the disinfection vehicle during the ultraviolet disinfection process and the weakening of the ultraviolet irradiation intensity by dust in the disinfected air environment. Summary of the Invention

[0004] Therefore, the present invention provides an ultraviolet disinfection vehicle with an adjustable irradiation device to overcome the problems in the prior art that the stability of the ultraviolet lamp tube decreases due to the increase in the center of gravity of the disinfection vehicle during the ultraviolet disinfection process and the dust in the disinfected air environment weakens the ultraviolet irradiation intensity.

[0005] To achieve the above object, the present invention provides an ultraviolet disinfection vehicle with an adjustable irradiation device, including:

[0006] A disinfection vehicle body;

[0007] An ultraviolet disinfection mechanism, which is connected to the disinfection vehicle body and is used to disinfect a target disinfection area, including an ultraviolet lamp tube for emitting ultraviolet light to the target disinfection area and a rotation assembly connected to the ultraviolet lamp tube for changing the rotation speed of the ultraviolet lamp tube;

[0008] A moving mechanism, which is connected to the main body of the disinfection vehicle and is used to change the target disinfection area and the traveling angle of the disinfection vehicle;

[0009] A detection mechanism, which is connected to the main body of the disinfection vehicle, including an ultraviolet intensity detection component arranged below the rotating component for detecting the ultraviolet intensity of the target disinfection area and an air humidity sensor partially arranged below the ultraviolet intensity detection component for detecting the air humidity of the target disinfection area;

[0010] A control mechanism, which is respectively connected to the ultraviolet disinfection mechanism, the moving mechanism and the detection mechanism, and is used to determine the stability of the ultraviolet disinfection mechanism according to the variance of the ultraviolet intensity of several points at the same height in the target disinfection area, so as to determine whether to adjust the traveling angle,

[0011] Or, determine the interference degree of dust on ultraviolet disinfection and the dust interference adjustment method according to the change amount of the ultraviolet intensity of the ground area. The interference adjustment method includes adjusting the moving speed of the disinfection vehicle, or adjusting the rotation speed of the rotating component according to the maximum difference amount of air humidity.

[0012] Further, it further includes a power supply mechanism respectively connected to the main body of the disinfection vehicle for supplying power to the moving mechanism, the ultraviolet disinfection mechanism, the detection mechanism and the control mechanism.

[0013] Further, the moving mechanism includes:

[0014] A universal wheel set, which is arranged below the main body of the disinfection vehicle and is used to drive the main body of the disinfection vehicle to move;

[0015] A power motor, which is connected to the universal wheel set and is used to drive the universal wheel set to rotate.

[0016] Further, the ultraviolet intensity detection component includes:

[0017] A first ultraviolet sensor, which is arranged on the side surface of the main body of the disinfection vehicle close to the rotating component and is used to detect the ultraviolet intensity of several points at the same height in the target disinfection area;

[0018] A second ultraviolet sensor, which is arranged below the first ultraviolet sensor and is used to detect the ultraviolet intensity of the ground area.

[0019] Further, the control mechanism is respectively connected to the first ultraviolet sensor and the rotating assembly, and is used to obtain the ultraviolet intensities at several points with the same height in the target disinfection area, and calculate the variance according to the ultraviolet intensities at several points with the same height in the target disinfection area. If the variance is greater than a preset second variance, it is determined that the stability of the ultraviolet disinfection mechanism does not meet the requirements, and the traveling angle is increased;

[0020] Wherein, the traveling angle is an obtuse angle formed by the disinfecting vehicle body and the forward direction.

[0021] Further, the increase amplitude of the traveling angle is positively correlated with the variance.

[0022] Further, the control mechanism is respectively connected to the first ultraviolet sensor and the second ultraviolet sensor, and is used to initially determine that the interference degree of the dust on the ultraviolet disinfection exceeds the allowable range when the variance is greater than a preset first variance and less than or equal to the preset second variance, and obtain the ultraviolet intensity of the ground area, and calculate the change amount of the ultraviolet intensity of the ground area per unit time. If the change amount is greater than a preset second change amount, it is secondarily determined that the interference degree of the dust on the ultraviolet disinfection exceeds the allowable range, and the moving speed of the disinfecting vehicle is reduced;

[0023] Wherein, the change amount of the ultraviolet intensity of the ground area per unit time is the absolute value of the difference between the ultraviolet intensity detected by the second ultraviolet sensor at the start moment of the unit time and the ultraviolet intensity detected at the end moment of the unit time.

[0024] Further, the reduction amplitude of the moving speed of the disinfecting vehicle is positively correlated with the change amount of the ultraviolet intensity.

[0025] Further, the control mechanism is respectively connected to the air humidity sensor and the moving mechanism, and is used to obtain the air humidity at the start moment and the end moment of the monitoring period under the condition that the change amount is greater than a preset first change amount and less than or equal to the preset second change amount, and calculate the difference amount of the air humidity, and screen out the maximum difference amount. If the maximum difference amount is greater than or equal to the preset maximum difference amount, the rotation speed of the rotating assembly is increased;

[0026] Wherein, the difference amount of the air humidity is the absolute value of the difference between the air humidity at the start moment of the monitoring period and the air humidity at the end moment of the monitoring period.

[0027] Further, the increase amplitude of the rotation speed of the rotating assembly is positively correlated with the maximum difference amount.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows. The system of the present invention is provided with an ultraviolet disinfection mechanism, a moving mechanism, a detection mechanism and a control mechanism. By setting a rotatable ultraviolet lamp tube to change the irradiation direction, ultraviolet rays can evenly cover all corners of the disinfection area, improving the comprehensiveness and uniformity of disinfection; by setting a detection mechanism to detect the ultraviolet intensity, the effectiveness of ultraviolet output during the disinfection process is improved, thereby improving the disinfection effect; by setting a control mechanism to determine the stability of the ultraviolet disinfection mechanism. Since the center of gravity of the disinfection vehicle is unstable during the movement of the disinfection vehicle and the rotation of the ultraviolet lamp tube, the stability of the ultraviolet disinfection mechanism decreases. By adjusting the traveling angle, the influence of the forward resistance on the stability is weakened, and the improvement of the stability of the ultraviolet lamp tube is achieved. By determining the degree of interference of dust on the detection, due to the movement of dust carried by bacteria or the movement of dust caused by environmental changes, the interference of dust in the air on the ultraviolet intensity detection increases. By determining the dust interference adjustment method, the improvement of the stability of ultraviolet disinfection and the improvement of the accuracy of ultraviolet disinfection are achieved.

[0029] Furthermore, the system of the present invention is provided with a first ultraviolet sensor and a second ultraviolet sensor. By detecting the ultraviolet intensity in different regions, it helps to discover the problems of instability of the ultraviolet disinfection mechanism and the decrease of ultraviolet output caused by dust accumulation, thereby achieving the improvement of the disinfection effect of the ultraviolet mechanism.

[0030] Furthermore, the system of the present invention is provided with a preset first variance and a preset second variance. Since the center of gravity of the disinfection vehicle is unstable when the disinfection vehicle moves forward and the ultraviolet lamp tube is lifted, and affected by air resistance, when it is determined that the stability of the ultraviolet disinfection mechanism does not meet the requirements, by increasing the traveling angle to weaken the influence of air resistance during the forward movement on the stability of the disinfection vehicle, the improvement of the stability of the ultraviolet disinfection mechanism is further achieved.

[0031] Furthermore, the system of the present invention is provided with a preset first change amount and a preset second change amount. Since the movement of dust caused by environmental changes during the forward movement of the disinfection vehicle interferes with the ultraviolet rays, resulting in a decrease in the disinfection intensity of the ultraviolet rays reaching the disinfection area, by reducing the moving speed of the disinfection vehicle to reduce the dust movement state, the increase in the accuracy of the detection mechanism is achieved, and further the reduction of the interference degree of dust on ultraviolet disinfection is achieved.

[0032] Furthermore, by setting a preset maximum difference amount, the system of the present invention can detect the influence degree of dust on the ultraviolet intensity by detecting the air humidity, because the humidity difference in different disinfection areas is large, and the air fluidity and dust fluidity in the disinfection areas with different humidities are strong, which will increase the dust on the ultraviolet lamp tubes. When the maximum difference amount of air humidity does not meet the requirements, the rotation speed of the rotating component is increased to shake off the aging particles and dust on the lamp tubes, thereby reducing the influence of the dust attached to the lamp tubes on the ultraviolet lamp tubes, and improving the accuracy of ultraviolet disinfection.

[0042] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 as shown, which are respectively the overall structural schematic diagram, the overall structural block diagram, the detection mechanism block diagram, and the moving mechanism block diagram of the ultraviolet disinfection vehicle of the adjustable irradiation device according to the embodiments of the present invention. An ultraviolet disinfection vehicle with an adjustable irradiation device of the present invention includes:

[0043] A disinfection vehicle body 6;

[0044] An ultraviolet disinfection mechanism, which is connected to the disinfection vehicle body 6 and is used to disinfect the target disinfection area, including an ultraviolet lamp tube 1 for emitting ultraviolet rays to the target disinfection area and a rotation assembly connected to the ultraviolet lamp tube 1 for changing the rotation speed of the ultraviolet lamp tube 1;

[0045] A moving mechanism, which is connected to the disinfection vehicle body 6 and is used to change the traveling angle of the target disinfection area and the disinfection vehicle;

[0046] A detection mechanism, which is connected to the disinfection vehicle body, including an ultraviolet intensity detection component arranged below the rotation assembly for detecting the ultraviolet intensity of the target disinfection area and an air humidity sensor 3 partially arranged below the ultraviolet intensity detection component for detecting the air humidity of the target disinfection area;

[0047] A control mechanism, which is respectively connected to the ultraviolet disinfection mechanism, the moving mechanism, and the detection mechanism, and is used to determine the stability of the ultraviolet disinfection mechanism according to the variance of the ultraviolet intensities of several same-height points in the target disinfection area to determine whether to adjust the traveling angle,

[0048] or, determine the interference degree of dust on ultraviolet disinfection and the dust interference adjustment method according to the change amount of the ultraviolet intensity of the ground area, and the interference adjustment method includes adjusting the moving speed of the disinfection vehicle or adjusting the rotation speed of the rotation assembly according to the maximum difference amount of the air humidity.

[0049] In implementation, the system of the present invention is provided with an ultraviolet disinfection mechanism, a moving mechanism, a detection mechanism and a control mechanism. By setting a rotatable ultraviolet lamp tube 1 to change the irradiation direction, ultraviolet rays can evenly cover all corners of the disinfection area, improving the comprehensiveness and uniformity of disinfection; by setting a detection mechanism to detect the ultraviolet intensity, the effectiveness of ultraviolet output during the disinfection process is improved, thereby enhancing the disinfection effect; by setting a control mechanism to determine the stability of the ultraviolet disinfection mechanism. Since during the movement of the disinfection vehicle and the rotation of the ultraviolet lamp tube 1, the center of gravity of the disinfection vehicle is unstable, resulting in a decrease in the stability of the ultraviolet disinfection mechanism, by adjusting the traveling angle to weaken the influence of the forward resistance on the stability, the improvement of the stability of the ultraviolet lamp tube 1 is achieved. By determining the degree of interference of dust on the detection, due to the movement of dust carried by bacteria or the movement of dust caused by environmental changes, the interference of dust in the air on the ultraviolet intensity detection increases. By determining the dust interference adjustment method, the improvement of the stability of ultraviolet disinfection and the improvement of the accuracy of ultraviolet disinfection are realized.

[0050] Specifically, the control mechanism is a PLC controller.

[0051] Specifically, the rotating assembly includes:

[0052] A lamp tube connecting member 7, which is fixedly connected to the disinfection vehicle body 6 and is respectively connected to the ultraviolet lamp tube 1 and the disinfection vehicle body 6, for fixing the ultraviolet lamp tube 1 on the disinfection vehicle body 6;

[0053] A rotating shaft 8, which is arranged between the lamp tube connecting member 7 and the ultraviolet lamp, for transmitting a rotational torque from the vertically downward direction to the horizontal direction perpendicular to the forward direction to the ultraviolet lamp tube 1;

[0054] A rotating motor (not shown in the figure), which is connected to the rotating shaft 8 for providing the rotational power of the rotating shaft 8.

[0055] Specifically, the size, shape and material of the lamp tube connecting member 7 can be changed without affecting its realization of the above functions. The preferred embodiment of the material of the lamp tube connecting member 7 is composite plastic.

[0056] Specifically, it further includes a power supply mechanism respectively connected to the disinfection vehicle body 6 for supplying power to the moving mechanism, the ultraviolet disinfection mechanism, the detection mechanism and the control mechanism.

[0057] Specifically, the preferred embodiment of the power supply mechanism is a lithium battery (not shown in the figure).

[0058] Specifically, on the surface of the disinfection vehicle body 6 below the rotating shaft 8 connected to the ultraviolet sensor assembly, there is a groove larger than the outer contour size of the ultraviolet lamp tube 1.

[0059] Specifically, the moving mechanism includes:

[0060] Five sets of universal wheels, which are arranged below the disinfection vehicle body 6 to drive the disinfection vehicle body 6 to move;

[0061] A power motor (not shown in the figure), which is connected to the five sets of universal wheels to drive the five sets of universal wheels to rotate.

[0062] Specifically, the bottom surface of the disinfection vehicle is square, and four universal wheels 5 with the same size and specification are arranged at the four top corner positions of the bottom of the disinfection vehicle body 6.

[0063] Specifically, the ultraviolet intensity detection component includes:

[0064] A first ultraviolet sensor 2, which is arranged on the side surface of the disinfection vehicle body 6 close to the rotating component to detect the ultraviolet intensity at several points with the same height in the target disinfection area;

[0065] A second ultraviolet sensor 4, which is arranged below the first ultraviolet sensor 2 to detect the ultraviolet intensity of the ground area.

[0066] In implementation, the system of the present invention sets the first ultraviolet sensor 2 and the second ultraviolet sensor 4, and by detecting the ultraviolet intensity in different areas, helps to discover the problems of unstable ultraviolet disinfection mechanism and decreased ultraviolet output caused by dust accumulation, thereby improving the disinfection effect of the ultraviolet mechanism.

[0067] Specifically, the control mechanism is respectively connected to the first ultraviolet sensor 2 and the rotating component to obtain the ultraviolet intensity at several points with the same height in the target disinfection area, and calculate the variance according to the ultraviolet intensity at several points with the same height in the target disinfection area. If the variance is greater than the preset second variance, it is determined that the stability of the ultraviolet disinfection mechanism does not meet the requirements, and the traveling angle is increased;

[0068] Wherein, the traveling angle is an obtuse angle formed by the disinfection vehicle body 6 and the forward direction.

[0069] Specifically, the increase amplitude of the traveling angle is positively correlated with the variance.

[0070] In implementation, the general value range of the preset first variance is [0.065 μW 2 / cm 4 , 0.088 μW 2 / cm 4 , and the general value range of the preset second variance is [0.94 μW2 / cm 4 ,1.05 μW 2 / cm 4 。

[0071] Preferably, a preferred embodiment of the preset first variance is 0.8 μW 2 / cm 4 ,and a preferred embodiment of the preset first variance is 0.96 μW 2 / cm 4 。

[0072] Specifically, when the difference between the variance of the ultraviolet intensity at several points with the same height in the target disinfection area and the preset second variance is within 0.01 μW 2 / cm 4 , the traveling angle increases by 5°; when the difference between the variance of the ultraviolet intensity at several points with the same height in the target disinfection area and the preset second variance exceeds 0.01 μW 2 / cm 4 ,for every 0.01 μW 2 / cm 4 exceeded, the traveling angle increases by 3°. For example, if the variance of the ultraviolet intensity at several points with the same height in the target disinfection area is 1 μW 2 / cm 4 and the traveling angle is 90° at this time, the traveling angle increases to 90° + 5° + 3°×3 = 104°.

[0073] In implementation, the system of the present invention sets the preset first variance and the preset second variance. Since the disinfection vehicle moves forward and the ultraviolet lamp tube 1 is lifted, and the influence of air resistance causes the center of gravity of the disinfection vehicle to be unstable. When it is determined that the stability of the ultraviolet disinfection mechanism does not meet the requirements, the traveling angle is increased to weaken the influence of air resistance during the forward movement on the stability of the disinfection vehicle, and further improve the stability of the ultraviolet disinfection mechanism.

[0074] Specifically, the control mechanism is respectively connected to the first ultraviolet sensor 2 and the second ultraviolet sensor 4, and is used to initially determine that the interference degree of the dust on the ultraviolet disinfection exceeds the allowable range when the variance is greater than the preset first variance and less than or equal to the preset second variance, and obtain the ultraviolet intensity of the ground area, and calculate the change amount of the ultraviolet intensity of the ground area per unit time. If the change amount is greater than the preset second change amount, it is secondarily determined that the interference degree of the dust on the ultraviolet disinfection exceeds the allowable range, and the moving speed of the disinfection vehicle is reduced;

[0075] Wherein, the change amount of the ultraviolet intensity in the ground area per unit time is the absolute value of the difference between the ultraviolet intensity detected by the second ultraviolet sensor 4 at the start time of the unit time and the ultraviolet intensity detected at the end time of the unit time.

[0076] Specifically, the reduction amplitude of the moving speed of the disinfection vehicle is positively correlated with the change amount of the ultraviolet intensity.

[0077] In implementation, the general value range of the preset first change amount is [3 μW / cm 2 , 6 μW / cm 2 , and the general value range of the preset second change amount is [7 μW / cm 2 , 10 μW / cm 2 .

[0078] Preferably, the preferred embodiment of the preset first change amount is 5 μW / cm 2 , and the preferred embodiment of the preset second change amount is 8 μW / cm 2 .

[0079] Specifically, if the difference between the change amount of the ultraviolet intensity in the ground area per unit time and the preset second change amount is within 1 μW / cm 2 , the moving speed of the disinfection vehicle is reduced by 0.1 m / s; if the difference between the change amount of the ultraviolet intensity in the ground area per unit time and the preset second change amount exceeds 1 μW / cm 2 , for every 1 μW / cm 2 exceeded, the moving speed of the disinfection vehicle is reduced by 0.2 m / s. For example, if the change amount of the ultraviolet intensity in the ground area per unit time is 10 μW / cm 2 , and the current moving speed of the disinfection vehicle is 5 m / s, the moving speed is reduced to 5 m / s - 0.1 m / s - 0.2 m / s = 4.7 m / s.

[0080] In implementation, by setting the preset first change amount and the preset second change amount in the system of the present invention, due to the interference of dust movement caused by environmental changes during the forward movement of the disinfection vehicle on the ultraviolet rays, the disinfection intensity of the ultraviolet rays reaching the disinfection area is reduced. By reducing the moving speed of the disinfection vehicle to reduce the dust movement state, the accuracy of the detection mechanism is increased, and further, the interference degree of dust on ultraviolet disinfection is reduced.

[0081] Specifically, the control mechanism is respectively connected to the air humidity sensor 3 and the moving mechanism, and is used to obtain the air humidity at the start time and the end time of the monitoring period under the condition that the change amount is greater than the preset first change amount and less than or equal to the preset second change amount, calculate the difference amount of the air humidity, screen out the maximum difference amount, and if the maximum difference amount is greater than or equal to the preset maximum difference amount, increase the rotation speed of the rotating assembly;

[0082] Wherein, the difference amount of the air humidity is the absolute value of the difference between the air humidity at the start time of the monitoring period and the air humidity at the end time of the monitoring period.

[0083] Specifically, the increase amplitude of the rotation speed of the rotating assembly is positively correlated with the maximum difference amount.

[0084] Specifically, the air humidity is the relative air humidity detected by the air humidity sensor 3.

[0085] In practice, the general value range of the preset maximum difference amount is [0.5%, 0.9%].

[0086] Preferably, a preferred embodiment of the preset maximum difference amount is 0.8%.

[0087] Specifically, if the difference between the maximum difference amount of the air humidity and the preset maximum difference amount is within 0.1%, the rotation speed of the rotating assembly is increased by 0.08 rpm; if the difference between the maximum difference amount of the air humidity and the preset maximum difference amount exceeds 0.1%, for every 0.1% exceeded, the rotation speed of the rotating assembly is increased by 0.05 rpm. For example, the maximum difference amount of the air humidity is 1.2%, the current rotation speed of the rotating assembly is 0.5 rpm, and the rotation speed is increased to 0.5 rpm + 0.08 rpm + 0.05 rpm × 3 = 0.73 rpm.

[0088] In practice, by setting the preset maximum difference amount in the system of the present invention, due to the large humidity difference in different disinfection areas, the air fluidity and dust fluidity in the disinfection areas with different humidities are strong, which in turn leads to an increase in dust on the ultraviolet lamp tube 1. By detecting the air humidity, the influence degree of the dust on the ultraviolet intensity is determined. When the maximum difference amount of the air humidity does not meet the requirements, by increasing the rotation speed of the rotating assembly, the aging particles and dust on the lamp tube are shaken off, thereby reducing the influence of the dust attached to the lamp tube on the ultraviolet lamp tube 1, and realizing the improvement of the accuracy of ultraviolet disinfection.

[0089] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
