Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet detection, in particular to an ultraviolet illumination inspection bracket. Background Art

[0002] Ultraviolet disinfection is a common disinfection method. As ultraviolet lamps are used frequently, the ultraviolet light will decay, resulting in insufficient illumination. According to the requirements of the domestic ultraviolet intensity indicator card, it is necessary to be 1m under the ultraviolet lamp, and after turning on the light for 5 minutes, irradiate with ultraviolet light for one minute. During the inspection, the radiation intensity value of the new ultraviolet lamp should be ≥90μW / cm2, and the radiation intensity value of the old ultraviolet lamp in use should be ≥70μW / cm2, otherwise, the ultraviolet lamp should be replaced.

[0003] At present, when testing ultraviolet lamps, it is necessary to hang them above the lamp tube through a bracket, wait for a period of time, and then read the ultraviolet intensity value. During this period, the measurement personnel are usually under direct exposure to ultraviolet rays, which seriously endangers their health, and the detection parameters are difficult to guarantee.

[0004] After searching, a Chinese patent with publication number CN205403949U discloses an auxiliary bracket for monitoring the irradiation intensity of ultraviolet lamps. The structure places the indicator card on a pallet for monitoring. The telescopic rod is composed of multiple sets of rods that are sequentially assembled. When not in use, the sets of rods at each level are connected together, which greatly reduces the length and facilitates storage. When in use, pull the hook hard to expand the sets of rods at each level to the maximum extent, thereby realizing the detection of ultraviolet lamps.

[0005] However, in actual use, since the indicator card needs to be placed one meter from the bottom of the ultraviolet lamp and tested for one minute during the detection process, the structure only achieves height adjustment by stretching the multi-stage sleeve rod, but it is difficult to control the irradiation distance of the ultraviolet lamp, the detection accuracy of the ultraviolet lamp is not high, and the stability is low. In view of this, the utility model proposes an ultraviolet illumination inspection bracket. Utility Model Content

[0006] The utility model provides an ultraviolet illumination inspection bracket to solve the technical problems existing in the prior art.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultraviolet illumination inspection bracket, comprising a vertical pole, an outer sleeve of the vertical pole is provided with a triangular bracket for supporting the vertical pole, an inner pole is provided inside the vertical pole, a placement box is provided at the top end of the inner pole, a bearing plate is provided inside the placement box, shaft pins are provided at both ends of the bearing plate, a servo motor is provided at one end of the placement box, a connecting rod is provided at the bottom of the placement box, and a timer is provided at the bottom end of the connecting rod, and a distance measuring structure is provided at one end of the placement box.

[0011] In order to be able to place and clamp the ultraviolet illumination test paper, preferably, an embedding groove is opened on the surface of the supporting plate, and the ultraviolet illumination test paper is placed inside the embedding groove. Two elastic paddles are provided on the surface of the supporting plate on both sides of the ultraviolet illumination test paper, and a protrusion is provided at the bottom of the elastic paddle, and the protrusion is on the surface of the ultraviolet illumination test paper.

[0012] In order to ensure that the detection height of the ultraviolet illumination test paper meets the detection requirements, preferably, the ranging structure includes a support plate, the support plate is installed on the side wall of the placement box, the surface of the support plate is provided with a T-slot, a T-block is slidably arranged inside the T-slot, and a ranging ruler is arranged on the top of the T-block.

[0015] 1. By setting up the distance measuring structure, the distance measuring ruler can be connected to the inside of the T-slot opened on the support plate through the T-block, so as to realize the vertical installation of the distance measuring ruler. The distance measuring ruler is used to measure whether the distance between the placement box and the ultraviolet lamp meets one meter, which meets the detection value of the ultraviolet lamp, improves the detection accuracy, and can facilitate the operator to assemble and dismantle the distance measuring ruler without affecting the occupied area;

[0016] 2. The ultraviolet illumination test paper is clamped in the embedded groove of the carrier plate through the elastic pick, so as to install the ultraviolet illumination test paper, and the inner rod slides inside the vertical rod, so as to adjust the height of the ultraviolet illumination test paper inside the placement box according to the situation. The servo motor drives the shaft pin to rotate so that the flip plate flips inside the placement box, and the ultraviolet illumination test paper can be flipped and adjusted to ensure that the ultraviolet lamp can irradiate the surface of the ultraviolet illumination test paper for testing;
