Description

Technical Field

[0001] The utility model belongs to the technical field of water quality sampling, and in particular relates to an intelligent unmanned water quality sampling station equipment integration mode and system. Background Art

[0002] Unmanned water sampling stations can remotely monitor water quality parameters such as pH, dissolved oxygen, conductivity, turbidity, ammonia nitrogen, nitrates, and phosphates in real time. If water quality is abnormal or exceeds preset thresholds, an alarm will be immediately issued, initiating appropriate emergency plans and measures to reduce potential environmental impacts. These parameters can also be regularly recorded and transmitted to terminals, allowing them to summarize water quality conditions in various areas and support subsequent water quality assessment, trend analysis, and decision-making.

[0003] Environmental factors such as meteorological conditions can significantly impact water quality. For example, temperature can affect vertical stratification and density gradients in water, thereby impacting dissolved oxygen distribution and water circulation. However, existing unmanned water sampling stations typically sample water quality based on preset intervals and remote control, rather than based on meteorological conditions. This limitation prevents timely and effective monitoring and feedback of water quality changes.

[0004] Therefore, this application proposes an intelligent unmanned water quality sampling station equipment integration mode and system. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated model and system for intelligent unmanned water sampling stations, thereby overcoming the drawbacks of existing unmanned water sampling stations, which generally perform water sampling based on preset intervals and remote command control, rather than on meteorological conditions. This limitation results in the inability to monitor and provide feedback on water quality changes in a timely and effective manner. The specific technical solution is as follows:

[0006] The intelligent unmanned water quality sampling station equipment integration mode and system include a water quality sensor, a water quality sampler, a data recording unit, a data transmission unit, a positioning device, a remote control unit and a meteorological sensor. The water quality sensor includes a pH sensor, a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, a turbidity sensor and a COD sensor. The water quality sensor is used to test the data of the sampled water; the water quality sampler includes a mounting plate, a water pump, a sampling tube, a retractable roller and a motor. The mounting plate is equipped with a water pump, one end of the sampling tube is connected to the water pump inlet, and the other end of the sampling tube is located below the water surface. The retractable roller is rotatably mounted on the mounting plate, one end of the retractable roller is connected to the output end of the motor, and the sampling tube is wound around the retractable roller; the meteorological sensor is connected to the data transmission unit, and the meteorological sensor includes a temperature sensor, a humidity sensor, an air pressure sensor, a wind speed sensor, a wind direction sensor, a precipitation sensor and a radiation sensor.

[0007] Preferably, it also includes a distance sensor and an angle sensor. The distance sensor is installed on the side of the mounting plate close to the water surface and is used to monitor the water surface height to adjust the depth of the sampling tube. The angle sensor is installed on the mounting plate and is used to measure the inclination angle of the sampling tube.

[0008] Preferably, it also includes an Internet server, which is electrically connected to the positioning device and is used to obtain real-time information from the Meteorological Bureau.

[0009] Preferably, a shielding plate is installed on the top of the wind speed sensor, and the vertical projection area of ​​the shielding plate completely covers the wind speed sensor.

[0010] Preferably, the meteorological sensor is electrically connected to the water quality sampler, and when the rate of change of the value measured by the meteorological sensor is greater than a threshold value, the water quality sampler is triggered to take a sample.

[0011] Preferably, it further includes a camera, which is electrically connected to the data transmission unit and is used to observe the external environment.

[0012] An intelligent unmanned water quality sampling station system includes a cloud server, a mobile terminal, a fixed terminal and the above-mentioned unmanned water quality sampling station equipment integration mode, wherein the mobile terminal and the fixed terminal provide a connection between the cloud server and the data transmission unit and the remote control unit.

[0013] Compared with the existing technology, the utility model has the following beneficial effects:

[0014] 1. This utility model combines a meteorological sensor with a water quality sampler. When the rate of change of the value measured by the meteorological sensor exceeds a threshold, the water quality sampler triggers sampling, thereby timely monitoring the impact of meteorological parameters on water quality. Compared with existing unmanned water quality sampling stations, this application can effectively monitor and provide feedback on water quality changes in a timely manner.

[0015] 2. This utility model uses a distance sensor to promptly detect water level changes and an angle sensor to measure the sampling tube's tilt angle, deriving a compensation length. This activates a motor to adjust the sampling tube's retraction and extension, thereby obtaining water quality samples at precise underwater depths. Simultaneously, a remote control unit controls the motor's rotation of the retraction rollers based on the distance sensor to adjust the retraction and extension of the sampling tube, thereby obtaining water quality samples at the target depth. This improves the integrated model and system practicality of the intelligent unmanned water sampling station. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Next, the embodiments are described in detail. Figures 1 to 3 To enable those skilled in the art to better understand the present invention:

[0024] The intelligent unmanned water quality sampling station equipment integration mode and system includes a water quality sensor 1, a water quality sampler 2, a data recording unit 3, a data transmission unit 4, a positioning device 5, a remote control unit 6 and a meteorological sensor 7. The water quality sensor 1 includes a pH sensor, a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, a turbidity sensor and a COD sensor. The water quality sensor 1 is used to test the data of the sampled water. At regular intervals, the water quality sampler will extract samples for water quality testing. The data recording unit 3 is used to collect and record the data detected by the water quality sensor 1, and then the data transmission unit 4 and the cloud server send it to the mobile terminal and the fixed terminal for the convenience of staff to view. The positioning device 5 is used to determine the location of the water quality sampling station. In conjunction with the Internet server 8, it can obtain real-time meteorological information of the positioning area, which can be mutually verified with the meteorological sensor 7.

[0025] The water sampler 2 includes a mounting plate 201, a water pump 202, a sampling tube 203, a retractable roller 204, and a motor 205. The water pump 202 is mounted on the mounting plate 201. One end of the sampling tube 203 is connected to the inlet of the water pump 202, and the other end of the sampling tube 203 is located below the water surface. The retractable roller 204 is rotatably mounted on the mounting plate 201. One end of the retractable roller 204 is connected to the output end of the motor 205, and the sampling tube 203 is wound around the retractable roller 204. The sampling tube 203 is generally provided with a counterweight to prevent the sampling tube 203 from swinging significantly due to the water flow, which affects the accuracy of the sampling depth and the stability of the sample. For water quality samples of different depths, a starting motor 205 can be provided to drive the retractable roller 204 to rotate and adjust the retractable amount of the sampling tube 203, so that the port of the sampling tube 203 reaches the accurate water depth and obtains accurate water quality parameters.

[0026] The distance sensor 206 is mounted on the side of the mounting plate 201 close to the water surface and is used to monitor the water surface height to adjust the depth of the sampling tube 203. The angle sensor is mounted on the mounting plate 201 and is used to measure the tilt angle of the sampling tube 203. The distance sensor 206 promptly detects changes in the water level, and the angle sensor measures the tilt angle of the sampling tube 203 to determine the compensation length, thereby starting the motor 205 to adjust the retraction and extension of the sampling tube 203 to obtain a precise underwater water quality sample. At the same time, the remote control unit 6 can control the motor 205 to rotate the retraction roller 204 based on the distance sensor 206 to adjust the retraction and extension of the sampling tube 203 to obtain a water quality sample at the target depth, thereby improving the practicality of the intelligent unmanned water quality sampling station equipment integration model and system.

[0027] Meteorological sensor 7 is connected to data transmission unit 4 and includes a temperature sensor, humidity sensor, air pressure sensor, wind speed sensor, wind direction sensor, precipitation sensor, and radiation sensor. Meteorological environment parameters are closely related to various water quality parameters. For example, wind speed can affect the surface agitation and mixing of water. Strong winds may cause water mixing to be more uniform, affecting the depth of the vertical mixing layer, thereby altering physical, chemical, and biological processes within the water. Warmer water is typically located at the surface, while colder water is often located at depth. This vertical stratification affects the distribution of dissolved oxygen in the water and its circulation. Precipitation events can increase the volume of runoff and rivers, potentially changing the depth and flow rate of the water, and thus affecting the concentration distribution of suspended matter, dissolved matter, and nutrients within the water. Meteorological sensor 7 is electrically connected to water quality sampler 2. When the rate of change of the value measured by meteorological sensor 7 exceeds a threshold, water quality sampler 2 triggers sampling. Compared to existing unmanned water sampling stations, this application can effectively monitor and provide feedback on water quality changes in a timely manner.

[0028] A shield is installed on top of the wind speed sensor. The shield's vertical projection area completely covers the wind speed sensor. This reduces the amount of rainwater hitting the fan blades on the wind speed sensor, thereby reducing wind speed detection errors.

[0029] The camera is electrically connected to the data transmission unit 4. The camera is used to observe the external environment. When the staff observes the situation outside the meteorological sensor 7, they can remotely control and continue sampling and analysis.

[0030] An intelligent unmanned water quality sampling station system includes a cloud server, a mobile terminal, a fixed terminal and the above-mentioned unmanned water quality sampling station equipment integration mode, the mobile terminal and the fixed terminal provide a connection between the cloud server and the data transmission unit 4 and the remote control unit 6.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention.
