Description
Technical Field
[0001] This utility model relates to the technical field of nutrient analyzers, specifically a long-term online low-maintenance nutrient analyzer. Background Technology
[0002] A nutrient analyzer is an analytical instrument used to monitor the nutrient composition of water bodies. It primarily employs spectrophotometry and ion exchange column methods to detect various parameters such as phosphate, nitrate, nitrite, silicate, and ammonia nitrogen. This instrument is widely used in water quality analysis of various water bodies, including seawater, industrial wastewater, and groundwater, as well as in the fields of soil solutions and plant extracts. However, current nutrient analyzers generate a large amount of heat during prolonged use, which can easily damage internal components, leading to excessively high maintenance frequency. Therefore, we propose a long-term online, low-maintenance nutrient analyzer. Utility Model Content
[0003] The purpose of this invention is to provide a long-term online low-maintenance nutrient analyzer, which has the advantages of long-term online operation and low maintenance. It solves the problem that current nutrient analyzers generate a lot of heat during long-term use, which can easily damage internal components and lead to excessively high maintenance frequency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a long-term online low-maintenance nutrient analyzer, comprising a protective box, a storage groove on the top of the protective box, mounting grooves on both the left and right ends of the bottom of the storage groove, an electric telescopic rod fixedly connected to the front and rear ends of the bottom of the mounting groove, a mounting platform fixedly connected to the top of the electric telescopic rod, an analyzer body mounted on the top of the mounting platform, a motor fixedly connected to the back of the analyzer body's inner cavity, a fan blade fixedly connected to the motor's output shaft, heat dissipation holes on the top of the analyzer body's inner cavity, a filter screen inserted into the inner cavity of the analyzer body, and a temperature detector and an airflow detector fixedly connected to the top of the analyzer body's inner cavity.
[0005] Preferably, a display is fixedly connected to the front of the protective box, and the input terminal of the display is electrically connected to the output terminals of the temperature detector and the air flow rate detector.
[0006] Preferably, an alarm is fixedly connected to the center of the front of the protective box, and a PLC controller is fixedly connected to the right end of the front of the protective box. The output terminal of the PLC controller is electrically connected to the input terminal of the alarm, motor and electric telescopic rod, and the input terminal of the PLC controller is electrically connected to the output terminal of the temperature detector and the air flow rate detector.
[0007] Preferably, air inlets are provided on both the upper and lower sides of the back of the analyzer body, and a cover plate is hinged to the right end of the top of the storage slot.
[0008] Preferably, the front and rear ends of both sides of the protective box are fixedly connected to fixing blocks, and bolts are provided on the fixing blocks.
[0009] Preferably, a battery slot is provided at the middle of the lower part of the inner cavity of the protective box, and a storage battery is fixedly connected to the inner cavity of the battery slot.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The storage slot on the top of the protective box of this utility model provides a dedicated protective space for the analyzer body. With the hinged cover on the top, the storage slot can be closed when the equipment is not in operation, preventing the analyzer body from being damaged by external objects when not in use. The electric telescopic rod installed in the slot at the bottom of the storage slot can drive the mounting platform and the analyzer body on the top to rise and fall flexibly. When in operation, the analyzer body is raised; when not in use, the analyzer body is lowered. The motor on the back of the analyzer body drives the fan blades to rotate, and outside air enters through the air intake hole on the back. After being filtered by the filter screen, it forms a clean airflow, which carries away the internal heat and is discharged from the heat dissipation hole on the top, forming a complete cycle of "air intake-filtration-heat dissipation-exhaust". This can improve the heat dissipation effect and reduce the maintenance frequency. The filter screen adopts a plug-in design, which can be pulled out and replaced without tools, further reducing the difficulty of maintenance.
[0011] 2. The display on the front of the protective box of this utility model can display the internal temperature of the equipment monitored by the temperature detector and the airflow speed monitored by the airflow velocity detector in real time. Operators can intuitively grasp the status of the equipment without remote query, which is convenient for quick on-site judgment. The PLC controller on the front of the protective box can receive temperature and flow velocity data. If the temperature is too high or the airflow velocity is too low, the alarm will be activated immediately to issue an audible and visual warning, which can detect and deal with faults in advance and avoid long-term loss of monitoring data.

When in operation, the analyzer body 6 is raised; when not in use, it is lowered. The motor 19 on the back of the analyzer body 6 drives the fan blades 20 to rotate. Outside air enters through the rear air intake 18, is filtered by the filter 11 to form a clean airflow, carries away internal heat, and is exhausted through the top heat dissipation vent 7, forming a complete cycle of "intake-filtration-heat dissipation-exhaust," which improves heat dissipation and reduces maintenance frequency. The filter 11 adopts a plug-in design, allowing for easy replacement without tools, further reducing maintenance difficulty.
[0018] Example 2: Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, a display 2 is fixedly connected to the front of the protective box 1. The input terminal of the display 2 is electrically connected to the output terminals of the temperature detector 16 and the air velocity detector 17.

A battery slot 13 is provided in the middle of the lower part of the inner cavity of the protective box 1. A storage battery 15 is fixedly connected to the inner cavity of the battery slot 13.
[0019] The display 2 on the front of the protective box 1 in this technical solution can display the internal temperature of the equipment monitored by the temperature detector 16 and the airflow speed monitored by the airflow detector 17 in real time. Operators can intuitively grasp the status of the equipment without remote query, which is convenient for quick on-site judgment. The PLC controller 10 on the front of the protective box 1 can receive temperature and flow rate data. If the temperature is too high or the airflow speed is too low, the alarm 8 will be activated immediately to issue an audible and visual warning, which can detect and deal with faults in advance and avoid long-term loss of monitoring data.
[0020] The working principle of this utility model is as follows: The storage slot 5 at the top of the protective box 1 provides a dedicated protective space for the analyzer body 6.

The electric telescopic rod 21 in the mounting slot 14 at the bottom of the storage slot 5 can flexibly raise and lower the mounting platform 12 and the analyzer body 6 at the top. When in operation, the analyzer body 6 is raised; when not in use, it is lowered. The motor 19 on the back of the analyzer body 6 drives the fan blades 20 to rotate. Outside air enters through the rear air intake 18, and after being filtered by the filter screen 11 to form a clean airflow, it carries away internal heat and is discharged through the top heat dissipation vent 7. The system forms a complete cycle of "intake-filtration-heat dissipation-exhaust," which improves heat dissipation and reduces maintenance frequency. The filter 11 adopts a plug-in design, which can be pulled out for replacement without tools, further reducing maintenance difficulty. The display 2 on the front of the protective box 1 can display the internal temperature of the equipment monitored by the temperature detector 16 and the airflow speed monitored by the airflow detector 17 in real time. Operators can intuitively grasp the status of the equipment without remote query, which is convenient for quick on-site judgment. The PLC controller 10 on the front of the protective box 1 can receive temperature and flow rate data. If the temperature is too high or the airflow speed is too low, the alarm 8 will be activated immediately to issue an audible and visual warning, which can detect and deal with faults in advance and avoid long-term loss of monitoring data.
