Description

Technical Field

[0001] The invention relates to the technical field of water environment monitoring equipment, and in particular to a water environment ecological heavy metal pollution monitoring equipment. Background Art

[0002] The heavy metal content in water is undoubtedly one of the important criteria for measuring water quality. In the current practice of monitoring the heavy metal content in water environment ecology, optical monitoring methods are usually widely used. Its specific working principle is: specific monitoring light is emitted on one side of the water sample, and a light receiving module is set on the other side to receive the filtered light. Due to the significant differences in the light absorption capacity of different types of metal ions, by comparing the difference between the radiated light and the received light, it is possible to achieve quantitative analysis of metal ions in the water body, and then complete the monitoring of heavy metals in the water environment ecology.

[0003] However, this optical monitoring method faces some key problems in practical applications. First, when the water sample is transported to the monitoring tube for monitoring, the overall monitoring state is static. In this case, the heavy metal ions in the water sample will appear unevenly distributed. This is because in static water samples, metal ions may gradually precipitate or aggregate in specific areas due to the influence of various factors such as gravity and intermolecular forces, resulting in large differences in metal ion concentrations at different locations. When performing optical monitoring, this uneven distribution will cause large errors in the monitoring results. Secondly, during the monitoring process, the monitoring position of the optical monitoring module is usually fixed, which means that only water samples in a specific area can be monitored, and the monitoring range is greatly limited.

[0004] To this end, we propose a water environment ecological heavy metal pollution monitoring device to solve the above problems. Summary of the invention

[0029] The optical monitoring unit 18 includes a light emitter 181 and a light receiving module 182. Both the light emitter 18 and the light receiving module 182 are fixedly mounted on the monitoring frame 17, and the light emitter 18 and the light receiving module 182 are arranged relative to each other. The light receiving module 182 is electrically connected to the PLC controller 21. By setting the light emitter 18 and the light receiving module 182, the light receiving module 182 can feed back the corresponding electrical signal changes to the PLC controller 21 for data recording based on the different heavy metal ion contents in different water samples, so as to obtain monitoring data.

[0030] A joint control mechanism 19 that cooperates with two reciprocating screws 16 is provided in the monitoring chamber 3. The joint control mechanism 19 includes a worm 191, a servo motor 192 and two worm wheels 193. The worm 191 is rotatably arranged in the monitoring chamber 3, and one end of the worm 191 is transmission-connected to the servo motor 192. The two worm wheels 193 are respectively fixedly sleeved on the corresponding reciprocating screws 16, and the two worm wheels 193 are meshed with the worm 191. Through the transmission cooperation between the worm 191 and the two worm wheels 193, the servo motor 192 can control the two reciprocating screws 16 to rotate synchronously, thereby avoiding the cost of adding additional driving equipment.

[0031] A reciprocating drive mechanism 20 matched with the drain pipe 6 is arranged in the drive chamber 4, a PLC controller 21 is arranged on the monitoring box 2, and the PLC controller 21 is used to control various electrical equipment, the reciprocating drive mechanism 20 includes an incomplete gear 201, a first gear 202, a second gear 203 and a spring 204, the incomplete gear 201 is rotatably arranged in the drive chamber 4, and the transmission shaft of the incomplete gear 201 is connected to the drive motor 22, the spring 204 is fixedly arranged in the drive chamber 4, and the force-bearing end of the spring 204 is fixedly sleeved with the first gear 202. The second gear 203 is fixedly sleeved on the discharge tube 6, the incomplete gear 201 is meshed with the first gear 202, and the first gear 202 is meshed with the second gear 203. Through the incomplete gear 201, the first gear 202 can be reciprocated for transmission. In conjunction with the transmission of the spring 204 and the second gear 203, the discharge tube 6 can be reciprocated, and then the transparent monitoring tube 7 can be reciprocated. Rotation, so that the heavy metal ions in the water sample in the transparent monitoring tube 7 can be evenly diffused to avoid gathering in one place and affecting the monitoring of the optical monitoring unit 18.

[0032] The operating steps of the present invention are: Sampling stage: First, the peristaltic pump 12 is used to quantitatively sample the water in the water environment. The peristaltic pump 12 uses its precise flow control capability to ensure that the amount of water sampled each time is accurate and consistent. After the sampling is completed, the water sample is transported to the transparent monitoring tube 7. The material design of the transparent monitoring tube 7 allows light to pass through well, providing the necessary conditions for subsequent light monitoring.

[0033] Stage of promoting uniform distribution of heavy metal ions: Start the drive motor 22. The drive motor 22 serves as a power source and provides initial power for the operation of the entire device. The drive motor 22 drives the incomplete gear 201 to rotate. The special design of the incomplete gear 201 enables it to intermittently mesh with the first gear 202 during rotation. Under the transmission cooperation of the spring 204 and the second gear 203, the drain pipe 6 drives the transparent monitoring tube 7 to reciprocate. The spring 204 plays a role in storing energy and transmitting power in this process. When the incomplete gear 201 is meshed with the first gear 202, the spring 204 is gradually tightened to store energy. When the incomplete gear 201 is disengaged from the first gear 202, the spring 204 releases energy and drives the first gear 202 to continue rotating, thereby realizing the reciprocating rotation of the drain pipe 6 and the transparent monitoring tube 7. This causes the water sample in the transparent monitoring tube 7 to shake, which promotes the good diffusion of heavy metal ions in the water body and realizes uniform distribution. The uniformly distributed heavy metal ions can ensure that the data monitored by the optical monitoring unit 18 is more accurate and reliable.

[0034] Light monitoring stage: The light transmitter 18 transmits monitoring light to the water sample. The light emitted by the light transmitter 18 has a specific wavelength and intensity, which can be partially absorbed by the heavy metal ions in the water sample. The light receiving module 182 on the other side receives the filtered light. The light receiving module 182 can accurately detect the changes in light intensity and wavelength after passing through the water sample. Since different metal ions have different light absorption abilities, the metal ions in the water body can be quantitatively analyzed based on the difference between the radiated light and the received light. This monitoring method based on optical principles has high sensitivity and accuracy. The light receiving module 182 feeds back the monitoring data in the form of electrical signals to the PLC controller 21 for recording. The PLC controller 21, as the core control unit of the entire monitoring equipment, can process and analyze the received electrical signals and store the monitoring data.

[0035] Multi-directional monitoring stage: After the servo motor 192 is started, the servo motor 192 controls the rotation of the worm 191 with its precise speed control and powerful torque output. The worm 191, as a transmission component, transmits the power of the servo motor 192 to the two worm wheels 193. Under the transmission cooperation of the two worm wheels 193, the two reciprocating screws 16 rotate synchronously. The transmission of the worm wheel 193 and the worm 191 is self-locking, which can ensure that after the servo motor 192 is stopped, the reciprocating screw 16 will not rotate arbitrarily due to external force. The two reciprocating screws 16 drive the optical monitoring unit 18 to reciprocate up and down through the monitoring frame 17. The design of the monitoring frame 17 enables the optical monitoring unit 18 to be stably installed thereon and rotate with the rotation of the reciprocating screw 16. By moving up and down and coordinating with the transparent monitoring tube 7, the optical monitoring unit 18 can perform multi-directional monitoring. This multi-directional monitoring can cover different positions in the transparent monitoring tube 7, thereby improving the comprehensiveness and accuracy of the monitoring. During the monitoring process, multiple groups of monitoring data will be generated. The light receiving module 182 in the optical monitoring unit 18 will feed back these data to the PLC controller 21 for recording. The PLC controller 21 can store and analyze these data in real time. After the monitoring is completed, the built-in calculation module of the PLC controller 21 adds the recorded groups of data and takes the average value to ensure the accuracy of the monitoring data. By averaging multiple groups of data, accidental errors can be reduced and the reliability of the monitoring results can be improved.

[0036] Cleaning stage: When the monitoring is completed, if the transparent monitoring tube 7 needs to be cleaned, the solenoid valve 27 on the discharge pipe 6 is opened, and the cleaning pump 13 is started. The solenoid valve 27 can accurately control the on-off of the discharge pipe 6 to ensure that the waste liquid can be discharged smoothly during the cleaning process. The cleaning pump 13 provides power for the cleaning process and transports the cleaning liquid in the cleaning box 14 to the transparent monitoring tube 7 for flushing. During the flushing process, the reciprocating drive mechanism 20 drives the transparent monitoring tube 7 to rotate to improve the flushing effect. The rotation of the transparent monitoring tube 7 can make the cleaning liquid fully contact the tube wall and various parts inside to ensure thorough cleaning. The waste liquid after flushing is discharged into the filter recovery chamber 5 through the drain pipe 6, and is filtered by the filter layer 8. The filter layer 8 can use multiple layers of filter materials of different materials, such as activated carbon, filter paper, etc., which can effectively remove impurities and heavy metal ions in the waste liquid. The filtered cleaning liquid is automatically replenished to the cleaning box 14 under the suction action of the cleaning pump 13 and the guiding action of the recovery pipe 15. The design of the recovery pipe 15 ensures that the filtered cleaning liquid can be smoothly returned to the cleaning box 14 for recycling. This process avoids the tedious operation of manual liquid addition and also avoids the waste of water resources.

[0037] Liquid level monitoring and alarm stage: When the level of the filtered liquid on the right side of the filter recovery chamber 5 reaches the limit value, the liquid level sensor 23 will feedback a signal to the PLC controller 21. The liquid level sensor 23 can monitor the liquid level in the filter recovery chamber 5 in real time. When the liquid level reaches the set limit value, it will send a signal in time, so that the PLC controller 21 controls the alarm 24 to start, so as to remind the staff to discharge the excess purified liquid in the filter recovery chamber 5. The alarm 24 can use sound and light alarms to ensure that the staff can promptly detect the situation of too high liquid level to prevent the purified and recovered cleaning liquid from exceeding the volume of the filter recovery chamber 5.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
