Description

Technical Field

[0001] This utility model relates to the field of online water quality monitoring technology, and in particular to an online algal toxin detector with algal activity measurement function. Background Technology

[0002] With the increasing severity of eutrophication, cyanobacterial blooms are frequently occurring globally, and the algal toxins they produce pose a serious threat to drinking water safety and the ecological environment. Therefore, real-time, online monitoring of algal toxins in water bodies is crucial. Online algal toxin detectors with algal activity measurement capabilities are widely used at key monitoring points such as water sources and water plants, as they are devices that can automatically complete sample collection, processing, and analysis.

[0003] In the actual operation of these online detectors, in order to ensure the accuracy of the test results, the water sample must undergo pre-processing operations such as filtration, enrichment or homogenization before entering the core analysis unit. As a front-end component that comes into direct contact with the source water, the filter element or packing inside the pre-processor will frequently become clogged or saturated due to the interception of a large number of suspended solids and impurities. It is a consumable that needs to be replaced regularly.

[0004] However, existing online monitoring instruments often prioritize the accuracy of the analysis unit during design, neglecting the maintainability of the equipment. For consumables such as preprocessors, the fixing method generally uses flanges secured with multiple bolts or complex snap-fit ​​cavities. When replacing them on-site, maintenance personnel not only need to carry a variety of special tools, but also have to perform cumbersome disassembly and assembly operations in a confined space. The whole process is time-consuming and labor-intensive, reducing maintenance efficiency and increasing the risk of monitoring data interruption due to prolonged downtime for maintenance.

[0005] Therefore, this invention proposes an online algal toxin detector with algal activity measurement to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of complex preprocessor fixing structure and inconvenient disassembly and assembly in existing online algal toxin detectors with algal activity measurement, which lead to time-consuming, labor-intensive and inefficient on-site maintenance, this utility model aims to provide an online algal toxin detector with algal activity measurement whose structure has been improved and can effectively solve the above problems.

[0007] This invention provides an online algal toxin detector with algal activity measurement, comprising: a detector, a fixed support, a support component, a preprocessor, and a fixing mechanism.

[0008] The fixed bracket is fixedly connected to the detector, and a vertical slot is provided in the fixed bracket. The bearing assembly includes a T-shaped slider and a bearing frame. The T-shaped slider is slidably connected to the slot of the fixed bracket, and the bearing frame is fixedly connected to the T-shaped slider. The preprocessor is detachably housed in the bearing frame.

[0009] Furthermore, the fixing mechanism includes a mounting base, a rotating shaft, a pressure plate, at least one fixing block, and bolts. The mounting base is fixedly connected to the fixing bracket, the rotating shaft is rotatably connected to the mounting base, and the pressure plate is fixedly connected to the rotating shaft for pressing the pre-processor in the locked position. The fixing block is fixed to the lower surface of the pressure plate, and the pressure plate is locked in the locked position by means of the bolt passing through the pressure plate and being threadedly connected to the fixing block.

[0010] Preferably, the fixing mechanism further includes a limiting sleeve, which is sleeved on both ends of the rotating shaft and abuts against the mounting base. This structure can effectively prevent the rotating shaft from axially moving during rotation, ensuring the smoothness and reliability of the opening and closing action of the pressure plate.

[0011] Preferably, the slot of the fixing bracket has an upward opening for the T-shaped slider to slide out from the opening. This design forms a convenient top-pull-out structure, which facilitates the quick installation and removal of the load-bearing component as a whole module.

[0012] Preferably, the bottom of the support frame is hollow. This structure provides ample operating and installation space for various pipelines connected to the bottom of the preprocessor, effectively avoiding structural interference and simplifying pipeline layout and maintenance.

[0013] Preferably, the detector further includes a first sample inlet pipe and a second sample inlet pipe, the outlet of the second sample inlet pipe is connected to the preprocessor, and the first sample inlet pipe is connected between the outlet of the preprocessor and the inlet of the detector, thereby forming a complete sample pretreatment and detection analysis flow path.

[0014] Preferably, the detector is provided with an interface for connecting external data devices. Through this interface, the detection results and data can be easily transmitted to an external display terminal or central control system, realizing data sharing and remote monitoring functions.

[0015] Preferably, the T-shaped slider is fixedly connected to one side of the support frame. This lateral connection layout makes the structure compact and ensures that the main body of the support frame can fully accommodate the preprocessor, while facilitating the connection of pipelines on the other side.

[0016] Preferably, there are two fixing blocks, which are symmetrically arranged on the lower surface of the pressure plate and locked by two bolts respectively. This makes the pressure applied to the top of the pre-processor more evenly distributed, thereby improving the reliability and sealing of the fixing.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of complex fixing structure and inconvenient disassembly and assembly of preprocessor in the prior art, which leads to low maintenance efficiency, by setting a bearing component that can slide along the inner groove of the fixed bracket and cooperating with a rotatable pressure plate to press and lock the preprocessor in the bearing component. It achieves the technical effect of realizing quick disassembly and assembly of preprocessor, simplifying operation steps and improving maintenance efficiency.

[0019] 2. This utility model solves the problem of loosening or inaccurate positioning of the fixing mechanism in the prior art during long-term use by setting a pressure plate that can rotate around the shaft and locking the pressure plate in the working position with bolts, and setting limit sleeves at both ends of the shaft. This achieves the technical effect of ensuring uniform and stable clamping force on the pre-processor, while ensuring the smooth and reliable operation of the locking mechanism itself, and improving the overall operational stability of the equipment.

[0020] 3. This utility model, by housing the preprocessor in a support frame and having the support frame engage with the slot of the fixed bracket via a T-shaped slider, forms a modular structure that can be pulled out as a whole. This solves the problem in the prior art that multiple scattered parts need to be disassembled when replacing components, which is cumbersome and prone to losing parts. It achieves the technical effect of modularizing the preprocessor, making the replacement process as convenient as changing a drawer, reducing the difficulty of operation, and improving the user experience.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 4 This utility model provides an online algal toxin detector with algal activity measurement, which aims to solve the problem of low maintenance efficiency caused by the complex fixed structure and inconvenient disassembly and assembly when replacing consumables in the prior art.

[0029] like Figure 1 and Figure 2 As shown, the online algal toxin detector with algal activity measurement includes a detector 1. A fixed bracket 502 is fixedly connected to one side of the detector 1. The fixed bracket 502 has a vertical slot inside, which guides the support component 6 to slide up and down. The support component 6 includes a support frame 601 and a T-shaped slider 602. The T-shaped slider 602 is fixedly connected to one side of the support frame 601 and slidably connected inside the slot of the fixed bracket 502. The support frame 601 is used to detachably house the preprocessor 4, which is used for water sample pretreatment. The bottom of the support frame 601 is hollow to facilitate pipeline connection and maintenance. In order to stably fix the support component 6, which houses the preprocessor 4, on the fixed bracket 502, the detector also includes a fixing mechanism 5. The fixing mechanism 5 enables rapid clamping, locking, and releasing of the preprocessor 4. The fixing mechanism 5 includes a mounting base 507 fixedly connected to the fixing bracket 502. A rotating shaft 504 is rotatably connected to the mounting base 507, and a pressure plate 501 is fixedly connected to the rotating shaft 504. When it is necessary to fix the preprocessor 4, the pressure plate 501 rotates to the locking position. In this position, the upper surface of the pressure plate 501 will press against the upper surface of the preprocessor 4. In order to achieve stable locking of the pressure plate 501 in the locking position, at least one fixing block 505 is fixedly connected to the lower surface of the pressure plate 501. A bolt 506 passes through the pressure plate 501 and forms a threaded connection with the fixing block 505, thereby firmly locking the pressure plate 501 and preventing it from rotating accidentally, thus ensuring continuous clamping force on the preprocessor 4.

[0030] To enhance the structural stability of the rotating shaft 504 during rotation, the fixing mechanism 5 also includes a limiting sleeve 503. This limiting sleeve 503 is fitted onto both ends of the rotating shaft 504, with its end face abutting against the side wall of the mounting base 507. This arrangement provides axial limiting for the rotating shaft 504, effectively preventing it from shifting or dislodging when rotating the pressure plate 501. This ensures that the pressure plate 501 can always rotate smoothly around a preset axis, providing a reliable mechanical basis for unlocking and locking operations. Simultaneously, to facilitate the removal of the bearing component 6, the slot on the fixing bracket 502 has an upward-facing opening. In the assembled state, the T-shaped slider 602 of the bearing component 6 slides within the slot. When the pre-processor 4 needs to be removed for replacement, after loosening the bolt 506 and rotating the pressure plate 501 to open it, the operator... The support component 6 can be slid upwards, and the T-shaped slider 602 will slide completely out from the upward opening along the guide of the slot, thereby removing the support frame 601 together with the internal preprocessor 4 as a whole module from the top of the fixed bracket 502. This top-pull-out structural design simplifies the maintenance and replacement operation process. In order to form a complete detection flow path, the detector also includes a first sample inlet pipe 3 and a second sample inlet pipe 7. The outlet of the second sample inlet pipe 7 is connected to the preprocessor 4 for transporting the water sample to be tested. The water sample after being processed by the preprocessor 4 is led out from the outlet of the preprocessor 4 through the first sample inlet pipe 3 and connected to the inlet of the detector 1, forming a complete sample processing and detection channel. In addition, the detector 1 is also provided with an interface 2 for connecting external data devices. Through this interface 2, the detection data can be output to an external computer or central control system.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0032] As one specific implementation method, please refer to Figure 3 and Figure 4 In order to make the clamping force of the pressure plate 501 on the pre-processor 4 more uniform and stable, the number of fixing blocks 505 is preferably two. The two fixing blocks 505 are symmetrically fixedly connected to the lower surface of the pressure plate 501. When the bolts 506 pass through the pressure plate 501 and are threadedly connected to the two fixing blocks 505, it can ensure that the pressure plate 501 will not deflect in the locked position, thereby applying balanced pressure to the upper surface of the pre-processor 4.

[0033] Furthermore, in order to form a stable sliding guide structure, the T-shaped slider 602 is fixedly connected to one side of the support frame 601. This connection method can be integral molding or achieved by welding, screw fixing, etc., so that the support frame 601 can move up and down smoothly as a whole along the slot of the fixed bracket 502 under the drive of the T-shaped slider 602.

[0034] To facilitate the connection and layout of the pipelines at the bottom of the preprocessor 4, the bottom of the support frame 601 is specially designed as a hollow structure. This hollow structure provides ample operating space for the connection of the first sample inlet pipe 3 and the second sample inlet pipe 7, avoids interference between the pipelines and the bottom of the support frame 601, and simplifies the installation and maintenance process.

[0035] Working principle: During testing, the water sample to be tested is transported to the preprocessor 4 through the second inlet pipe 7 for pretreatment operations such as filtration and homogenization. After processing, the water sample enters the detector 1 through the first inlet pipe 3 for subsequent data analysis. During this process, the bearing component 6 stably supports the preprocessor 4, while the fixing mechanism 5 firmly presses and fixes the preprocessor 4 in the working position through the locking action of the pressure plate 501 and bolts 506, ensuring the stability and sealing of the testing process.

[0036] When the preprocessor 4 needs to be replaced or maintained, the operation process demonstrates the core advantages of this utility model. First, the operator loosens and removes the bolt 506 to release the lock on the pressure plate 501. Then, the pressure plate 501 can be easily rotated to the side under the drive of the rotating shaft 504, completely clearing the space at the top of the preprocessor 4. When the pressure plate 501 rotates, the limiting sleeves 503 set at both ends of the rotating shaft 504 ensure that the rotating shaft 504 will not move axially, ensuring the smooth and reliable rotation operation. After the clamping force is released, the entire... The bearing component 6 can slide freely in the slot of the fixed bracket 502. The operator can directly pull the bearing component 6 upward. The T-shaped slider 602 moves smoothly under the guidance of the slot until it is completely separated from the opening at the top of the slot. Thus, the bearing frame 601 together with the pre-processor 4 inside it can be easily taken out as a whole module. Through this structure that combines sliding extraction and rotation pressing, this utility model simplifies the originally complicated disassembly and assembly process into a few intuitive steps, improves maintenance efficiency, and solves the problem of inconvenient replacement of consumables in the prior art.
