Description

Technical Field

[0001] This utility model relates to the field of ultraviolet lamp technology, and in particular to an ultraviolet lamp tube irradiation intensity detection device. Background Technology

[0002] An ultraviolet (UV) lamp is a type of light fixture that emits ultraviolet light. It is an essential tool for observing the fluorescence and phosphorescence characteristics of samples and is also a physical means of sterilization and disinfection. The wavelength range is 10-400 nm. After the UV lamp tubes are manufactured, the emitted UV radiation needs to be tested to determine whether its irradiance intensity is within acceptable limits.

[0003] A device for detecting the irradiance of ultraviolet lamps, with publication number CN116678495B, relates to the field of ultraviolet lamp irradiance detection technology. The key technical features are: a housing, characterized in that: a detection chamber is provided inside the housing, and a rotating mechanism for fixing ultraviolet lamps is provided inside the detection chamber; a photometric measuring stage is also provided outside the housing, with the measuring end of the photometric measuring stage close to the ultraviolet lamps; the rotating mechanism includes two conductive slip rings, a rotating rod, multiple fixing plates, and multiple lamp fixing slots; the two conductive slip rings are respectively fixedly connected to the top and bottom of the detection chamber, the top and bottom of the rotating rod are respectively fixedly connected to the output ends of the two conductive slip rings, and the ends of the multiple fixing plates are all fixedly connected to the side walls of the rotating rod.

[0004] The aforementioned testing device addresses the issue of personnel being directly exposed to ultraviolet radiation. Furthermore, the testing mechanism can simultaneously test multiple ultraviolet lamps, improving testing efficiency. However, because the ultraviolet lamps are clamped and fixed by a spring-driven sealing sleeve, the elasticity of the spring makes the fixation of the lamp sleeve unstable. The lamps are easily displaced due to vibration, affecting the stability of the testing process. Moreover, replacing ultraviolet lamps requires stopping testing and opening the swing door, making it impossible to replace them simultaneously with testing, further impacting efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient stability in fixing the lamp tube and the inability to replace it during testing, by proposing a device for detecting the irradiance intensity of ultraviolet lamp tubes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an ultraviolet lamp irradiance detection device, including a box, a rotating frame is rotatably installed inside the box, a number of lamp slots are installed on the outside of the rotating frame, and a pair of lamp holders for clamping ultraviolet lamps are slidably installed inside the lamp slots through a clamping assembly.

[0008] The clamping assembly includes a pair of arc-shaped rods fixedly installed on the inner walls of both sides of the housing. The two ends of the arc-shaped rods are chamfered. The far ends of the pair of lamp holders are fixedly connected to a drive rod that passes through the lamp tube groove through a pop-out assembly. The end of the drive rod located outside the lamp tube groove is slidably connected to the housing and the arc-shaped rods.

[0009] The inner and outer sides of the box are respectively equipped with loading and unloading components and radiation detection components.

[0010] Furthermore, the pop-out assembly includes a baffle fixedly mounted on the outer end of the drive rod, and a spring located outside the lamp tube slot is sleeved on the outer wall of the drive rod, with the two ends of the spring abutting against the lamp tube slot and the baffle respectively;

[0011] The baffle has a spherical groove at the end away from the spring, and a ball bearing is rotatably installed inside the spherical groove. The end of the ball bearing away from the spring is rotatably connected to the housing and the arc-shaped rod.

[0012] Furthermore, the loading and unloading assembly includes a horizontal groove on the outer wall of the box, and an outer arc plate adapted to the lamp tube groove is fixedly installed inside the horizontal groove. The upper and lower ends of the outer arc plate are fixedly connected to the box by bending plates. The outer wall of the outer arc plate has two openings, and the upper and lower openings are respectively fixedly installed with a loading groove and a unloading groove.

[0013] Furthermore, the rotating frame includes a rotating shaft rotatably installed inside the housing, with both ends of the rotating shaft passing through and rotatably connected inside the housing. Several sets of connecting rods are fixedly installed on the outer wall of the rotating shaft, and the end of each set of connecting rods away from the rotating shaft is fixedly connected to the lamp tube slot.

[0014] The outer end of the rotating shaft is fixedly connected to a pulley, a drive pulley is rotatably mounted on the outer wall of the housing, a handle is fixedly mounted on the outer side of the drive pulley, and the pulley and the drive pulley are connected by belt drive.

[0015] Furthermore, the radiation detection component includes an ultraviolet irradiator fixedly installed inside the housing. An arc-shaped baffle adapted to the lamp tube slot is fixedly installed inside the housing. A through hole is opened on the outer wall of the arc-shaped baffle, and a photometric measuring station is fixedly installed inside the through hole. The other end of the photometric measuring station is connected to the ultraviolet irradiator.

[0016] Furthermore, a baffle plate is fixedly connected to the end of the lamp holder away from the lamp tube groove to prevent the lamp tube from detaching from the lamp tube groove.

[0017] The ultraviolet lamp irradiance detection device proposed in this utility model has the following advantages: when the lamp slot rotates to the unloading slot, the lamp holder can automatically detach from the ultraviolet lamp and be discharged through the unloading slot. When the empty unloading slot rotates to the loading slot, a new ultraviolet lamp is loaded. Loading and unloading can be carried out without stopping the detection, which effectively improves the detection efficiency. At the same time, when the loading slot continues to rotate upward, the chamfer can be raised to push the drive rod inward and drive the two lamp holders to move closer and clamp and fix the ultraviolet lamp. The arc rod prevents the drive rod from moving outward, making the clamping and fixing of the ultraviolet lamp by the lamp holder more stable. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4As one embodiment of this utility model, a device for detecting the irradiance intensity of an ultraviolet lamp tube is disclosed, including a housing 1. A rotating frame 2 is rotatably mounted inside the housing 1. Several lamp tube slots 3 are mounted on the outer side of the rotating frame 2. A pair of lamp holders 5 for clamping ultraviolet lamp tubes are slidably mounted inside the lamp tube slots 3 through a clamping assembly 4. Preferably, a rectifier is provided inside the housing 1. The lamp holders 5 are matched with the lamp heads of the ultraviolet lamp tubes. A pair of conductive slip rings are mounted on the rotating frame 2, and the conductive slip rings are used to connect the power supply and the several lamp holders 5.

[0025] The clamping assembly 4 includes a pair of arc-shaped rods 41 fixedly installed on the inner walls of both sides of the housing 1. The two ends of the arc-shaped rods 41 are chamfered 42. The far ends of the pair of lamp holders 5 are fixedly connected to a drive rod 43 that passes through the lamp tube groove 3 through the pop-out assembly 6. The end of the drive rod 43 located outside the lamp tube groove 3 is slidably connected to the housing 1 and the arc-shaped rods 41. Preferably, the arc-shaped rods 41 are formed by opening a notch in the ring.

[0026] The inner and outer sides of the box 1 are respectively provided with loading and unloading components 7 and radiation detection components 8;

[0027] The rotating frame 2 drives several lamp slots 3 to rotate. When the lamp slot 3 rotates to the notch, the drive rod 43 disengages from the arc rod 41 and moves outward under the action of the pop-out component 6 and abuts against the box 1, thereby driving the lamp holder 5 to move outward. The loading and unloading component 7 puts the ultraviolet lamps into the lamp slots 3 in sequence and aligns the pins of the ultraviolet lamps with the pin holes on the lamp holder 5.

[0028] Continue to rotate the rotating frame 2 to drive the lamp tube slot 3 to rotate, so that the drive rod 43 disengages from the notch and slides along the chamfer 42 to the inside of the arc rod 41, and is pressed inward by the chamfer 42, so that the drive rod 43 drives the two lamp holders 5 to approach and clamp and fix the ultraviolet lamp tube.

[0029] At the same time, the pin of the ultraviolet lamp tube is inserted into the pin hole on the lamp holder 5, so that the pin of the ultraviolet lamp tube is connected to the conductive slip ring and rectifier through the lamp holder 5 to connect the power supply. As to how the conductive slip ring, rectifier, power supply and lamp holder 5 are connected to other necessary components to form a circuit to power and control the ultraviolet lamp tube, this is existing technology for those skilled in the art, and will not be described in detail here.

[0030] The lamp holder 5 is powered by a power supply and a conductive slip ring, which enables the ultraviolet lamp tube to be connected to the power supply for preheating and emitting light. After preheating, the lamp tube rotates with the lamp tube slot 3 to the radiation detection component 8, and the radiation detection component 8 detects the irradiance intensity of the ultraviolet radiation emitted by the ultraviolet lamp tube.

[0031] After testing, when the UV lamp tube continues to rotate with the lamp tube groove 3 to the loading and unloading assembly 7, the lamp tube groove 3 rotates again to the notch, causing the lamp holder 5 to move outward again and detach from the UV lamp tube, so that it can be discharged through the loading and unloading assembly 7.

[0032] In some embodiments, the pop-out component 6 includes a baffle 61 fixedly mounted on the outer end of the drive rod 43, and a spring 62 located outside the lamp tube groove 3 is sleeved on the outer wall of the drive rod 43, with the two ends of the spring 62 abutting against the lamp tube groove 3 and the baffle 61 respectively.

[0033] Wherein, the end of the baffle 61 away from the spring 62 is provided with a spherical groove 63, and a ball bearing 64 is rotatably installed inside the spherical groove 63. The end of the ball bearing 64 away from the spring 62 is rotatably connected to the housing 1 and the arc rod 41.

[0034] Spring 62 applies an outward pushing force to baffle 61, causing it to abut against housing 1 after disengaging from arc rod 41. Ball bearings 64 replace drive rod 43 and roll to connect with housing 1 and arc rod 41. The rolling ball bearings 64 can reduce the friction between housing 1 and arc rod 41.

[0035] Specifically, the loading and unloading assembly 7 includes a horizontal groove 71 formed on the outer wall of the housing 1. An outer arc plate 72 adapted to the lamp tube slot 3 is fixedly installed inside the horizontal groove 71. The upper and lower ends of the outer arc plate 72 are fixedly connected to the housing 1 by bending plates 73 respectively. Two openings 74 are formed on the outer wall of the outer arc plate 72. The loading groove 75 and the unloading groove 76 are fixedly installed inside the two openings 74 respectively. Preferably, the included angle between the two openings 74 is the same as the included angle between two adjacent lamp tube slots 3. The shape of the two openings 74 is the same as the groove at the outer end of the lamp tube slot 3.

[0036] When the lamp tube slot 3 rotates to the front side, it slides and connects with the outer arc plate 72 and is blocked by the outer arc plate 72. When it just rotates into the notch, the slot tilts downward and aligns with the lower end opening 74 and the feeding slot 76, so that the ultraviolet lamp tube that is detached from the lamp holder 5 enters the feeding slot 76 through the lower end opening 74, thereby completing the automatic feeding.

[0037] The lamp tube slot 3 continues to rotate and its opening tilts upward and aligns with the upper opening 74 and the feeding slot 75, so that the ultraviolet lamp tube can be placed into the lamp tube slot 3 through the feeding slot 75.

[0038] It should be noted that the rotating frame 2 includes a rotating shaft 21 rotatably installed inside the housing 1, and both ends of the rotating shaft 21 pass through and are rotatably connected inside the housing 1. Several sets of connecting rods 22 are fixedly installed on the outer wall of the rotating shaft 21. The end of each set of connecting rods 22 away from the rotating shaft 21 is fixedly connected to the lamp tube slot 3. Preferably, a conductive slip ring is fixedly installed on the outer wall of the rotating shaft, and the outer end of the conductive slip ring is fixedly connected to the inner wall of the housing 1. Several sets of connecting rods 22 are arranged in a circumferential array on the outer wall of the rotating shaft 21.

[0039] Wherein, a pulley 23 is fixedly connected to the outer end of the rotating shaft 21, a drive pulley 24 is rotatably mounted on the outer wall of the housing 1, a handle 25 is fixedly mounted on the outer side of the drive pulley 24, and the pulley 23 and the drive pulley 24 are connected by a belt 26 for transmission. Preferably, a horizontal shaft is fixedly mounted on the outer wall of the housing 1, and the drive pulley 24 is rotatably mounted on the outer wall of the horizontal shaft through a bearing.

[0040] The handle 25 drives the pulley 24 to rotate, and the belt 26 drives the pulley 23 and the shaft 21 to rotate, thereby driving the lamp tube slots 3 to rotate through several sets of connecting rods 22.

[0041] In detail, the radiation detection component 8 includes an ultraviolet irradiator 81 fixedly installed inside the housing 1. An arc-shaped baffle 82 adapted to the lamp tube slot 3 is fixedly installed inside the housing 1. A through hole 83 is opened on the outer wall of the arc-shaped baffle 82, and a photometric measuring stage 84 is fixedly installed in the through hole 83. The other end of the photometric measuring stage 84 is connected to the ultraviolet irradiator 81.

[0042] Preferably, the angle between the photometric measuring stage 84 and the feeding trough 76 is the same as the angle between two adjacent lamp tube slots 3. The outer wall of the housing 1 is provided with a mounting hole, and an ultraviolet irradiator 81 is fixedly installed in the mounting hole. The photometric measuring stage 84 is a hollow round tube used to simulate a dark room, and the probe of the ultraviolet irradiator 81 is fixedly installed inside the lower end of the hollow round tube. The axis of the hollow round tube is perpendicular to the axis of the rotating shaft.

[0043] When the lamp tube slot 3 drives the preheated ultraviolet lamp tube to rotate to the middle position of the arc baffle 82, the upper end of the hollow round tube points vertically to the ultraviolet lamp tube, thereby guiding the ultraviolet rays emitted by the ultraviolet lamp tube to the probe of the ultraviolet irradiator 81, so that the ultraviolet irradiation intensity can be detected by the ultraviolet irradiator 81.

[0044] Meanwhile, the UV lamp tube after the previous test rotates with the lamp tube slot 3 to the unloading slot 76 and rolls down into the unloading slot 76. After a new UV lamp tube is loaded into the previous empty lamp tube slot 3 loading slot 75 through the loading slot 75, the tested UV lamp tube is taken out.

[0045] Furthermore, the end of the lamp holder 5 away from the lamp tube groove 3 is fixedly connected to a baffle 9 for preventing the lamp tube from detaching from the lamp tube groove 3.

[0046] Working method: Rotate the handle 25 to rotate the rotating frame 2, which will drive several lamp tube slots 3 to rotate. When three adjacent lamp tube slots 3 are respectively in the feeding slot 75, the unloading slot 76 and the hollow tube, the upper two lamp tube slots 3 rotate to the notch. When they rotate to the notch, the drive rod 43 disengages from the arc rod 41 and moves outward under the action of the pop-out component 6 and abuts against the box 1, thereby driving the lamp holder 5 to move outward.

[0047] Place the new UV lamp tube into the empty lamp tube slot 3 above and align the UV lamp tube's pin with the pin hole on the lamp holder 5. When the UV lamp tube in the middle lamp tube slot 3 rotates to the notch, the tested UV lamp tube rolls into the feeding trough 76. The ultraviolet radiation emitted by the UV lamp tube is guided to the probe of the ultraviolet irradiator 81 for testing through the hollow tube.

[0048] Continue to rotate the rotating frame 2 to drive the lamp tube slot 3 to rotate, so that the drive rod 43 on the lamp tube slot 3 into which the new ultraviolet lamp tube is placed rotates upward, slides along the chamfer 42 to the inside of the arc rod 41, and is squeezed inward by the chamfer 42, so that the drive rod 43 drives the two lamp holders 5 to approach and clamp and fix the ultraviolet lamp tube.

[0049] At the same time, the pin of the ultraviolet lamp is inserted into the pin hole on the lamp holder 5. The lamp holder 5 is powered by the power supply, conductive slip ring and rectifier, and the new ultraviolet lamp is connected to the power supply. The preheating is completed as the new ultraviolet lamp continues to rotate to the hollow tube.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
