Description

Technical Field

[0001] The present invention relates to the technical field of rapid detection of environmental pollutants, and more particularly to a rapid detection device for environmental pollutants based on spectral characteristics. Background Art

[0002] In the existing technology, rapid detection devices for environmental pollutants based on spectral characteristics usually adopt optical detection principles, and realize qualitative and quantitative detection of pollutants by analyzing the absorption, scattering or fluorescence characteristics of water samples to light of specific wavelengths. However, such devices have obvious limitations in actual operation. During detection, a transparent detection tube containing a water sample needs to be placed in the light path of the optical detector, but the detection tube fixing structure design of the existing devices is often not reasonable. The common slot-type or threaded fixing methods are either difficult to achieve quick alignment or require cumbersome rotation operations. In field sampling or continuous detection scenarios, operators often need to repeatedly adjust the position of the detection tube to obtain stable readings, which not only reduces detection efficiency, but may also lead to unsatisfactory optical coupling and affect detection accuracy.

[0003] The fixing mechanism either lacks clamping force, causing the test tube to loosen during transportation, or clamps too tightly, causing the glass test tube to break. In addition, most devices do not have an integrated quick release mechanism, requiring two-handed operation to replace samples, and cannot adapt to emergency testing scenarios that require one-handed operation. These mechanical design defects greatly reduce the smoothness of the entire testing process, especially under harsh on-site testing conditions. The problem of inconvenient operation will be further magnified, seriously restricting the promotion and application value of the equipment in the field of environmental monitoring.

[0016] (3) Beneficial effects

[0017] Compared with the existing technology, the present invention provides a rapid detection device for environmental pollutants based on spectral characteristics, which has the following beneficial effects:

[0018] The device adopts a unique flip-up semicircular frame structure, which makes the installation and fixing process of the detection tube more efficient. In the initial state, the operator only needs to rotate the semicircular frame to a position aligned with the opening of the fixing frame to easily insert the detection tube. The fixing mechanism adopts a bidirectional compression spring and a one-way snap design. Just push the pull rod inward and the compression spring will automatically apply uniform pressure to firmly fix the detection tube on the optical detection path to avoid displacement due to vibration or improper operation. When the sample needs to be replaced, only the bidirectional plate needs to be pinched to quickly release the detection tube. The entire process does not require complicated operations, which greatly improves the convenience of on-site detection. It is especially suitable for continuous monitoring scenarios that require frequent sample replacement.

[0019] The device uses a motor-driven synchronous shaft and gear transmission system to drive the semicircular frame to rotate smoothly, allowing the detector to continuously scan along the outer wall of the detection tube. At the same time, the innovative acceleration belt and internal tooth meshing structure enable the detector to rotate along the fitting circle while revolving with the semicircular frame, achieving all-round coverage detection of the detection tube. This dual-motion mode ensures the comprehensive collection of spectral data and avoids the blind spot problem that may exist in traditional fixed detection, thereby improving the accuracy and reliability of the detection results. In addition, the meshing design of the fixed wheel and the acceleration belt further stabilizes the optical signal and reduces the interference of mechanical vibration, ensuring that the signal-to-noise ratio of the spectral data reaches the optimal level.

[0020] The overall structural design of the device fully considers the needs of human-computer interaction. The flip mechanism of the semicircular frame not only facilitates the installation of the detection tube, but also provides a stable motion trajectory during the detection process. The one-way buckle and progressive unlocking design of the fixing mechanism make the fixing and releasing operations of the detection tube intuitive and reliable, avoiding equipment damage caused by misoperation. At the same time, the linkage design of the bidirectional sleeve and variable pitch slot makes the unlocking process smoother. The operator only needs to pinch with one hand to complete the replacement of the detection tube.

[0021] This spectral-based rapid detection device for environmental pollutants achieves an efficient and accurate pollutant detection process through innovative mechanical transmission, dynamic scanning and convenient fixing design. Its advantages are not only reflected in the detection speed and accuracy, but also in simplifying the complex operating steps of traditional spectral detection equipment, making it more suitable for on-site rapid detection needs and providing reliable technical support for the field of environmental monitoring.

[0036] See also Figures 1 to 10, a rapid detection device for environmental pollutants based on spectral characteristics, includes a fixed frame 11 installed on the outside; it also includes a flipping mechanism, the flipping mechanism includes a follower groove 21 opened on the side wall of the fixed frame 11, a limit ring 22 is slidably installed in the follower groove 21, a follower wheel 23 is installed on the outer wall of the limit ring 22, a motor 24 is fixedly installed on the fixed frame 11, the protruding end of the motor 24 is connected to a synchronous shaft 25, two driving wheels 26 are fixedly installed on the synchronous shaft 25, the driving wheel 26 is meshed with the follower wheel 23, and two fixed wheels 27 are fixedly installed on the two fixed frames 11 respectively, and a semicircular frame 28 is installed on the limit ring 22. The flipping mechanism also includes a fitting groove 29 opened in the semicircular frame 28, an acceleration belt 210 is rotatably connected in the fitting groove 29, a fitting ring 211 is installed in the fitting groove 29, and the acceleration belt 210 is rotated. The inner wall is fitted on the fitting ring 211, and a plurality of external grooves 212 are provided on the outer wall of the acceleration belt 210. The fixed wheel 27 is engaged in the external groove 212. The fitting ring 211 is slidably connected with an acceleration block 213 at the upper limit. A plurality of internal teeth 214 are installed at equal intervals on the inner wall of the acceleration belt 210. The acceleration block 213 is installed with a follower tooth 215, and the follower tooth 215 is engaged with the internal tooth 214. Intermediate rods 216 are respectively installed at both ends of the semicircular frame 28, and a connecting wheel 217 is rotatably installed on the intermediate rod 216. The connecting wheel 217 is engaged with the internal tooth 214. An insertion rod 218 is installed on the acceleration block 213, and a detector 219 is installed on the insertion rod 218. An opening 220 is provided on the fixed frame 11, and a detection tube 221 is clamped and installed in the opening 220. The detector 219 is located on the side wall of the detection tube 221.

[0037] When fixing the detection tube 221, the semicircular frame 28 can be rotated to the same position as the opening 220 first. At this time, the detection tube 221 can be conveniently inserted into the fixing frame 11, and then the compression spring 35 is pressed on both sides of the detection tube 221. At this time, the detection tube 221 will be fixed. By rotating the semicircular frame 28, the detector 219 will be driven to perform detection along the detection tube 221, thereby completing the detection process.

[0038] When detection is required, it is necessary to drive the rotation of the semicircular frame 28. First, the motor 24 drives the rotation of the synchronous shaft 25. Since the driving wheel 26 is fixedly connected to the synchronous shaft 25 and the driving wheel 26 is engaged with the follower wheel 23, the semicircular frame 28 will be driven to rotate. At this time, the limit ring 22 will slide along the follower groove 21. Since the detector 219 is connected to the semicircular frame 28, it will rotate along the semicircular frame 28 to perform the detection process. A fixed wheel 27 is fixedly installed on the fixed frame 11, and the fixed wheel 27 is engaged with the external groove 212. Since the rotation of the semicircular frame 28 will drive the synchronous rotation of the acceleration belt 210, the fixed wheel 27 and the fixed frame 11 are in a fixed state, and the fixed wheel 27 is engaged with the external groove 212 on the outside of the acceleration belt 210. 2, thus causing the acceleration belt 210 to rotate on the two connecting wheels 217, and the follower gear 215 to engage with the internal gear 214, thereby driving the acceleration block 213 to slide along the fitting ring 211. At this time, the state is that the semicircular frame 28 rotates along the fixed frame 11, and the acceleration block 213 rotates along the fitting ring 211. Therefore, the detector 219 on the acceleration block 213 not only rotates along the semicircular frame 28 but also slides along the fitting ring 211. When the semicircular frame 28 rotates half a circle, the acceleration block 213 drives the detector 219 to rotate one circle. Therefore, it not only ensures that the detection tube 221 can be conveniently installed on the fixed frame 11, but also can completely drive the detector 219 to rotate and detect along the detection tube 221, thereby completing the spectral detection process.

[0039] The fixing mechanism includes a side sleeve 31 installed on the side wall of the fixing frame 11, and two two-way plates 32 are symmetrically slidably connected to the side sleeve 31, and a pull rod 33 is slidably connected in each side sleeve 31, and a pressure plate 34 is installed on the two pull rods 33. The fixing mechanism also includes two compression springs 35 installed on the pressure plate 34, and the two compression springs 35 are respectively pressed on the side wall of the detection tube 221, and a one-way rod 36 is slidably connected to the side wall of the side sleeve 31. A flat groove 37 is provided on the side wall of the pull rod 33, and the one-way rod 36 is stuck in the flat groove 37. A groove 38 is provided on the other side of each flat groove 37. A progressive groove 39 is provided on the other side of the one-way rod 36, and a top ball 310 is installed on each one-way rod 36, and a telescopic plate 311 is connected between the two top balls 310, and a return spring 312 is installed on the telescopic plate 311. The other end of the return spring 312 is connected to the side wall of the side sleeve 31, and each side sleeve 31 is symmetrically slidably connected with a two-way sleeve 313, and each two-way sleeve 313 is provided with a variable pitch groove 314, and each variable pitch groove 314 is respectively stuck on the top ball 310, and a plurality of tension springs 315 are installed at equal intervals between the two two-way sleeves 313, and the two-way plate 32 is pressed on the two-way sleeve 313.

[0040] When the detection tube 221 is installed on the fixing frame 11, the detection tube 221 needs to be fixed. First, the two pull rods 33 are respectively inserted into the side sleeves 31, and then the compression spring 35 is pressed on the side wall of the detection tube 221, and the flat groove 37 on the pull rod 33 is clamped on the one-way rod 36, thereby ensuring the one-way clamping effect and thus ensuring the fixing process. In simple terms, the pull rod 33 is inserted into the side sleeve 31 and pushed inward to complete the process of fixing the detection tube 221.

[0041] When it is necessary to unlock, pinch the two two-way plates 32. Since the two-way plates 32 are stuck on the two-way sleeves 313, the two symmetrical two-way sleeves 313 will be driven to move closer to each other. Then the pitch-changing groove 314 will press on the top ball 310 to push the top ball 310 outward, thereby unlocking the connection between the one-way rod 36 and the plane groove 37. At this time, the detection tube 221 can be taken out, and the unlocking process is completed. In simple terms, pinching the two two-way plates 32 will unlock the connection between the pull rod 33 and the side sleeve 31, and then pulling out the pull rod 33 to complete the unlocking process.

[0042] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one. In the above, all fixed connections are preferably considered to be welding. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
