Description

Technical Field

[0001] The present invention relates to the technical field of ultraviolet disinfection equipment detection, and particularly to a test device for ultraviolet disinfection lamps. Background Art

[0002] Medical ultraviolet lamps are devices that use ultraviolet rays for medical purposes such as sterilization and disinfection, and use ultraviolet rays to disinfect the air and the surfaces of objects in key departments such as operating rooms, delivery rooms, and intensive care units. Regularly turning on the ultraviolet lamp for a certain period of time can effectively kill bacteria and viruses in the air and reduce the risk of surgical infections; because the ultraviolet lamp is turned on for a long time and it is strictly prohibited for people to enter, it is generally turned on when getting off work at night. For the surfaces of objects such as hospital beds and desks and chairs in the ward, the ultraviolet lamp can also play a good disinfection role; however, the ultraviolet lamp is damaged as the usage time increases, which in turn affects the ultraviolet radiation intensity it can output. Therefore, it is necessary to regularly use an ultraviolet intensity detector to detect its radiation intensity. When the intensity is lower than the effective sterilization intensity, the ultraviolet disinfection lamp needs to be replaced in time.

[0003] Currently, there are two commonly used methods for detecting the irradiation intensity of ultraviolet lamps, namely the irradiance meter method and the indicator card method; however, no matter which method is used, it needs to be placed 1 meter directly below the ultraviolet lamp for irradiation; generally speaking, the installation height of the ultraviolet lamp is usually about 2 - 2.5 meters from the ground. When detecting the ultraviolet lamp, the irradiance meter or the indicator card is placed approximately 1 meter directly below the ultraviolet lamp. This 1-meter distance is an estimated value and cannot be verified, resulting in a certain error in the detection result. In order to detect the irradiation intensity of the ultraviolet lamp more accurately, a device for detecting the irradiation intensity of the ultraviolet lamp is needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide a test device for ultraviolet disinfection lamps.

[0005] The technical solution of the present invention is: a test device for ultraviolet disinfection lamps, which is placed below the ultraviolet disinfection lamp, including a lifting top plate and a laser pen; there are two laser pens, which are symmetrically arranged on both sides of the center of the lifting top plate. The axes of the two laser pens are coplanar and inclined towards the center of the lifting top plate; the included angle between the laser pen and the lifting top plate is α, and the distance between the two laser pens is L meters, and cotα = L / 2. Calculating the included angle between the laser pen and the lifting top plate according to the distance between the two laser pens and fixing it can directly mark and position the height, thus facilitating the adjustment of the device.

[0006] Preferably, mounting seats are arranged on both sides of the lifting top plate; the laser pen is installed in the mounting seat through an adjusting bolt, and the mounting seat clamps the laser pen; the mounting seat is a frame made of an elastic material; the laser pen is arranged inside the frame; a protractor is also arranged on the mounting seat; the adjusting bolt passes through the center of the protractor and the laser pen and then is connected to a nut; the axis of the adjusting bolt intersects with the axis of the laser pen; angle scales are arranged on the protractor; readings are provided beside the angle scales; the reading is the distance from the intersection point of the light rays of the two laser pens at the corresponding angle to the center of the lifting top plate. This facilitates adjusting the distance between the lifting top plate and the ultraviolet disinfection lamp as needed.

[0007] Preferably, a lifting adjusting rod and a base are arranged below the lifting top plate; the bottom of the lifting adjusting rod is vertically installed at the center of the base, and the top is connected to the lower bottom surface of the lifting top plate. This can facilitate adjusting the height of the lifting top plate.

[0008] Furthermore, a locking mechanism is arranged on the lifting adjusting rod. This can prevent the lifting adjusting rod from retracting by itself and enhance the structural stability of the device.

[0009] Preferably, a circular ring protruding upward is arranged at the center of the lifting top plate, and the inside of the circular ring is a detection area. This can place the indicator card or the irradiance meter in the detection area at the center of the lifting top plate, facilitating determining the straight-line distance between the indicator card or the irradiance meter and the ultraviolet disinfection lamp.

[0010] Preferably, a transition disk is arranged below the lifting top plate; the bottom of the transition disk is fixedly connected to the top of the lifting adjusting rod; a ball bearing is arranged between the transition disk and the lifting top plate; the inner ring of the ball bearing is fixed to the transition disk, and the outer ring is fixed to the bottom of the lifting top plate. This can rotate the lifting top plate for multiple positionings, ensuring the positioning accuracy of the device.

[0011] Furthermore, a number of radial slideways are arranged at the bottom of the lifting top plate. The slideways include two relatively parallel slide rails, and a number of slideways are circumferentially distributed around the center of the lifting top plate; a horizontally arranged U-shaped slider is slidably arranged in the slideways; a square radially arranged fixing block is arranged between the two slide rails, and the fixing block is fixed to the lifting top plate by screws, and the square fixing block is slidably matched with the U-shaped slider; a number of radially arranged adjusting blocks are fixed to the top surface of the transition disk, and the number of adjusting blocks is evenly arranged along the circumference and is opposite to the fixing block; the bottom of the U-shaped slider abuts against the top surface of the transition disk, and the lower part of the U-shaped slider is matched with the adjusting block; the sliding range of the U-shaped slider corresponds to the length of the adjusting block; the closed end of the U-shaped slider faces outward. By restricting the adjusting block and the square fixing block through the U-shaped slider, the structural stability of the device can be ensured, and after the U-shaped slider releases the restriction on the adjusting block and the square fixing block, the lifting top plate can be rotated and adjusted relative to the transition disk.
