Description

Technical Field

[0001] The embodiments of this utility model belong to the field of optical radiation measurement technology, and more specifically, relate to an ultraviolet intensity testing device. Background Technology

[0002] Ultraviolet (UV) lamps are widely used in hospitals, laboratories, schools, food processing plants, and other places due to their effective disinfection and sterilization capabilities. To ensure their disinfection effect, the UV intensity should be tested regularly using a UV intensity test card at a vertical distance of 1 meter below the lamp tube.

[0003] Currently, most known methods for testing ultraviolet (UV) intensity rely on simple fixed stands or temporary handheld test cards by the user. These existing methods have significant drawbacks: First, most fixed stands are bulky and lack telescopic or folding structures, making storage and carrying extremely inconvenient. Second, their operation is often not simple enough, making it difficult to accurately control and maintain the required 1-meter standard distance for testing, affecting measurement accuracy. Third, common stands are single-function and lack cleaning capabilities, while UV lamps require regular wiping to maintain light transmittance, requiring additional work from staff and increasing their workload. Furthermore, many stands have poorly designed clamping structures that cannot accommodate different types of UV lamps and lack scratch protection, posing a risk of lamp damage. Therefore, it is necessary to develop a testing device that integrates precise positioning, convenient operation, easy storage, and cleaning functions to solve the above problems.

[0013] In one embodiment of this utility model, a hook is provided at the suspension end of the tube body to cooperate with the operating ring to keep the movable clamp in a normally open state.

[0014] In one embodiment of this utility model, the test paper clip includes a connecting ring and a paper clip, wherein the connecting ring is disposed at the suspension end of the tube body; the paper clip is fixedly disposed on the outside of the connecting ring for holding the ultraviolet test paper.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see Figures 1 to 2 This utility model provides an ultraviolet intensity testing device, which includes: a tube body 100, a connecting base 200, a movable clamp, and a test paper clamp 400. The tube body 100 includes a clamping end and a suspension end, with a first transmission through hole 120 provided on the suspension end. The clamping end and the suspension end are divided by the center line of the long axis of the tube body 100. The connecting base 200 is threadedly connected to the clamping end of the tube body 100. The movable clamp is connected to the connecting base 200 via a rotating shaft 211. The test paper clamp 400 is movably disposed at the suspension end of the tube body 100 for clamping ultraviolet test paper. Note that some structural numbers are not shown in the figures, but this does not mean that the corresponding structures are not shown.

[0025] Typically, existing colorimetric methods based on UV test paper require the device to be mounted on the ground below the UV source. Controlling the distance between the UV test paper and the UV source is achieved using lifting devices or similar mechanisms. This method demands a certain level of ground flatness and stability, and requires manual adjustment through measurement. Even within acceptable error ranges, the process still involves a significant amount of work. To address these issues, and considering that existing UV sources are typically UV lamps, this invention, in one embodiment, abandons placing the testing device on the ground and instead uses a UV intensity testing device to suspend the UV test paper directly below the UV source. The process is as follows: The movable clamp is held on the ultraviolet lamp tube. Due to gravity, the suspension end of the tube body 100 is vertically suspended below the ultraviolet lamp tube. The length of the tube body 100 is set to the length required for testing, or a length scale from the top of the movable clamp is set on the tube body 100. The test paper clip 400 is set at the suspension end of the tube body 100 and can be adjusted according to the length scale and actual needs. The test paper clip 400 holds ultraviolet test paper, thus realizing the setup and use process without contacting the ground and without additional measurement of the distance between the ultraviolet source and the ultraviolet test paper. The workload is small and the accuracy is high.

[0026] Furthermore, since the ultraviolet intensity testing device is used by suspension, all materials used in the entire ultraviolet intensity testing device are lightweight materials, such as aluminum alloy, which ensures strength without damaging the ultraviolet lamp tube due to excessive weight.

[0027] To facilitate the opening and closing of the movable clamp during use, in one embodiment of this utility model, the movable clamp includes: a first clamping arm 310, a second clamping arm 320, an elastic connector 330, and a transmission rope 340. The first clamping arm 310 and the second clamping arm 320 are respectively connected to the connecting base 200 via a rotating shaft 211, and each is provided with a transmission connection through hole 311 and an elastic connection through hole 312. The elastic connector 330 is fixedly connected to the elastic connection through hole 312 and is used to provide tension for the clamping of the first clamping arm 310 and the second clamping arm 320; Transmission rope 340 includes: The first transmission rope 341 is fixedly connected at both ends to the transmission connection through holes 311 of the first clamping arm 310 and the second clamping arm 320, respectively; The second transmission rope 342 is disposed inside the tube 100. One end of the rope is fixedly connected to the middle of the first transmission rope 341, and the other end passes through the first transmission through hole 120 and is fixedly provided with an operating ring 343.

[0028] The movable clamp is powered by an elastic connector 330, which keeps the first clamping arm 310 and the second clamping arm 320 normally closed. The elastic connector 330 can be made of any elastic material to achieve the same purpose. In one embodiment of this invention, a spring is chosen as the elastic connector 330. Its elastic coefficient needs to be selected based on the material tolerance of the movable clamp and the compressive strength of the ultraviolet lamp, ensuring that it can safely hold the ultraviolet lamp without falling due to gravity. Furthermore, in this embodiment, the movable clamp can be opened via a transmission rope 340. When in use, pulling the operating ring 343 transmits the pulling force from the second transmission rope 342 to the first transmission rope 341. The two ends of the first transmission rope 341 then drive the first clamping arm 310 and the second clamping arm 320 to rotate outwards, thus opening the movable clamp.

[0029] To further ensure smooth pulling operation, the first clamping arm 310 and the second clamping arm 320 are symmetrically arranged about the axis of the tube body 100. This design ensures that the tension of the transmission rope 340 on the movable clamp is uniform. At the same time, the first clamping arm 310 and the second clamping arm 320 are arc-shaped claw structures. When closed, there is a protruding structure at the top of the first clamping arm 310 and the second clamping arm 320 to form a space to accommodate the ultraviolet lamp tube. At this time, the tension of the elastic connector 330 is borne by the existing protruding structure, and no additional pressure is exerted on the ultraviolet lamp tube.

[0030] Furthermore, since the opening and closing of the movable clamp is achieved by the tension of the transmission rope 340, in order to further save effort, in one embodiment of this utility model, the connecting base 200 further includes: auxiliary shafts 210, which are symmetrically distributed at both ends of the connecting base 200 about the axis of the tube body 100. The distance between the two auxiliary shafts 210 is greater than the distance between the transmission connection through holes 311 of the first clamping arm 310 and the second clamping arm 320. In this way, the second transmission rope 342 bypasses the auxiliary shaft 210 and connects to the transmission connection through holes 311, ensuring that the first clamping arm 310 and the second clamping arm 320 always act as effort-saving levers during outward rotation under the tension of the second transmission rope 342. This also increases the opening degree between the first clamping arm 310 and the second clamping arm 320, making it easier to clamp the ultraviolet lamp tube during use.

[0031] Meanwhile, the length of the entire ultraviolet intensity testing device can be inconvenient to carry. Therefore, this utility model embodiment provides two optimization methods: First, the clamping end and the suspension end are connected by threads or sleeves. When not in use, the clamping end and the suspension end of the tube body 100 can be separated to shorten the length for easy carrying. When in use, the two parts can be reconnected, and the workload is not large. The location where the clamping end and the suspension end are separated can be selected according to actual needs, with a preferred position being the middle of the long axis of the tube body 100.

[0032] Secondly, the clamping end is connected to the suspension end via a folding structure. Since a transmission rope 340 is provided inside the tube 100, the tube 100 can be folded and shortened by setting up the folding structure.

[0033] In addition, based on the second method, the folding mechanism can be further optimized into a retractable structure, which can be folded up and stored like an umbrella, making it more convenient.

[0034] Furthermore, since the ultraviolet intensity testing device provided in this embodiment of the present invention is fixed by clamping the ultraviolet lamp tube, it is inevitable that the ultraviolet lamp tube will be squeezed. To avoid damaging the ultraviolet lamp tube, in one embodiment of the present invention, the inner side of the first clamping arm 310 and the second clamping arm 320 also includes a buffer pad 360. The buffer pad 360 can be made of a soft material, such as a soft rubber strip. This invention does not limit the material. At the same time, to better adapt to actual needs, the material of the buffer pad 360 can be replaced with a lint-free cloth or other cleaning material, which can relieve pressure and clean both sides of the ultraviolet lamp tube. For the lower part of the ultraviolet lamp tube, in one embodiment of the present invention, the top of the first clamping arm 310 and the second clamping arm 320 also includes an arc-shaped cleaning structure 350. In use, the movable clamp is kept closed, and the lower part of the ultraviolet lamp tube can be cleaned by holding the tube body 100 directly. To further improve the use effect, this arc-shaped cleaning structure 350 can be combined with Velcro sponge and a cleaning cloth as a new cleaning structure, which is convenient to replace and will not affect other functions.

[0035] Furthermore, the movable clamp remains closed without external force. If it needs to remain open for an extended period, a continuous external force is required. To further reduce effort, in one embodiment of this invention, a hook 110 is provided at the suspension end of the tube 100 to cooperate with the operating ring to keep the movable clamp in a normally open state. When the movable clamp needs to be normally open, simply hook the operating ring 343 at one end of the first transmission rope 341 onto the hook 110 to achieve normal opening.

[0036] Please see Figures 1 to 3In one embodiment of this utility model, the test paper clip 400 includes a connecting ring and a paper clip 410, wherein the connecting ring is disposed at the suspended end of the tube 100; the paper clip 410 is fixedly disposed on the outside of the connecting ring for holding the ultraviolet test paper. In actual use, the distance between the test paper clip 400 and the ultraviolet lamp is a preset distance, usually 1m. However, since the diameters of different ultraviolet lamps are slightly different, the tube 100 is provided with a distance scale from the top of the movable clip, and the connecting ring can be moved to a more precise position on the tube 100. At the same time, the connecting ring can be fixed to the tube 100 in various ways, such as clamping structures, bolts, and elastic structures. Furthermore, since the ultraviolet intensity testing device irradiates the ultraviolet test paper held on the paper clip 410 by suspending it under the ultraviolet lamp, the position of the test paper clip 400 should avoid the obstruction of the movable clip and be placed on the unobstructed sides of the tube 100. Alternatively, a counterweight can be placed on the tube 100 on the other side of the paper clamp 410 to tilt the suspended end of the tube 100 toward the paper clamp 410, thereby further improving the irradiation effect. Considering the issue of gravity tilting, under normal circumstances, the weight of the test paper clamp will not cause significant tilting of the tube. If adjustment is required, it can be done by placing a level at the suspended end of the tube and moving the counterweight up and down with the tube.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
