Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically to an external measuring pool device for a floating automatic water quality monitoring station. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. With the continuous development of science and technology, water quality monitoring has evolved from fixed-location monitoring to mobile automatic monitoring. Automatic monitoring floating stations have been applied in water quality monitoring. Floating vessels are used as carriers to carry automated water quality monitoring stations, which can move flexibly on the water surface to achieve automatic online monitoring of water quality in different areas.

[0003] In automatic water quality monitoring, the water quality probe is a core component, and its normal operation and service life are crucial to the accuracy and reliability of the monitoring data. However, the aquatic environment is complex and variable, and the water quality probe is directly exposed to the water, making it susceptible to damage from factors such as water flow impact, collision with impurities in the water, and biological adhesion, which can lead to probe damage or decreased measurement accuracy. Furthermore, because the probe is immersed in water for extended periods, maintenance and management are challenging. Regular calibration, cleaning, and replacement of the probe require significant manpower, resources, and time, and may cause secondary damage during these operations.

[0004] Existing floating automatic water quality monitoring stations mostly employ built-in or external probe structures. Built-in probes involve placing a detection chamber inside the floating vessel, fixing the probe within a specific chamber, and using a pump to draw water into the chamber for monitoring. While built-in probes offer good protection against damage, the extended sampling pipeline can lead to data lag, and water temperature and dissolved oxygen levels are easily affected by the chamber environment, particularly air temperature. Currently, floating automatic water quality monitoring stations commonly use directly external probes. External probes are fixed to the outside of the hull, directly contacting the water for better monitoring. However, probes directly exposed to the water are susceptible to water flow impacts, collisions with floating debris, or biological attachment, leading to shortened lifespan and data distortion. Fixed probes can only measure data from a single water layer and cannot dynamically acquire water quality parameters (such as dissolved oxygen, pH, and turbidity) at different depths. In addition, the external probes also present maintenance difficulties. Probe maintenance requires disassembling the floating station or climbing the outside of the hull, which poses safety hazards and is inefficient.

[0005] While existing technologies include liftable probe designs, they lack physical protection structures for the probes, making them susceptible to water flow interference and resulting in insufficient stability. Therefore, there is an urgent need to develop new solutions that balance protection, monitoring scope, and ease of operation and maintenance. Utility Model Content

[0028] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] like Figures 1-4As shown, a floating automatic water quality monitoring station with an external measuring pool includes a fixed support 2, a measuring pool 4, and a winch device 9. The fixed support 2 is fixedly installed on the outside of the floating body 1, and a vertical guide rail 3 is provided inside the fixed support 2. The measuring pool 4 is slidably installed between the vertical guide rails 3, and the measuring pool 4 is connected to the winch device 9 through a winch rope 12. Water passage holes 6 are evenly opened on the lower half of the outer wall of the measuring pool 4. A water quality probe 7 is installed inside the measuring pool 4. By adopting this device, the problems of probe damage, fixed monitoring depth, and inconvenient operation and maintenance can be effectively solved, realizing in-situ multi-depth in-situ monitoring and efficient maintenance of water quality. In the specific operation process, the floating body 1 moves the entire measuring pool 4, and the winch device 9 lowers the measuring pool 4 into the water, thus ensuring that water is delivered into the measuring pool 4 during the movement of the floating body 1, and then the water quality is detected by the water quality probe 7 inside the measuring pool 4.

[0030] Furthermore, the measuring cell 4 has a square hollow structure and is made of a corrosion-resistant alloy.

[0031] Furthermore, the measuring pool 4 is equipped with a probe mounting base 8, and the water quality probe 7 is fixedly mounted on the probe mounting base 8. The water quality probe 7 is electrically connected to the floating vessel body 1 via a wire to achieve online water quality monitoring. Multiple sets of multi-parameter water quality probes 7 can be installed simultaneously using the probe mounting base 8, with each probe 7 integrating pH / DO / conductivity parameters. This enables the measurement of different types of indicators.

[0032] Furthermore, a top cover 5 is provided on the top of the measuring pool 4 for opening and closing the measuring pool 4; a small-aperture protective net is suspended on the outer wall of the measuring pool 4 at the location of the water passage 6, forming a secondary protection system with the water passage 6. The secondary protection system blocks large floating objects while allowing water flow, enabling in-situ monitoring; the top is equipped with a quick-release top cover 5 for easy replacement of the probe or cleaning of sediment in the pool.

[0033] Furthermore, all of the fixed brackets 2 are made of galvanized steel. The use of galvanized steel ensures structural strength while providing excellent corrosion resistance, thus effectively extending their service life.

[0034] Furthermore, the winch device 9 includes a winch motor, which is fixed to the deck of the floating vessel hull 1. A winch drum is mounted on the output shaft of the winch motor, and a winch rope 12 is wound around the winch drum. The winch rope 12 passes over the fixed pulley 13 at the top of the fixed bracket 2 and is connected to the measuring pool 4. The winch device 9 described above can be used to control the lifting and lowering of the measuring pool 4. During operation, the winch motor drives the winch drum, which in turn drives the winch rope 12, which in turn drives the connected measuring pool 4, thereby causing the measuring pool 4 to be lifted and lowered along the vertical guide rail 3.

[0035] Furthermore, a limiting groove 11 is formed between the vertical guide rails 3, and pulley blocks 10 are installed on the two outer side walls of the measuring pool 4. The pulley blocks 10 and the limiting groove 11 form a sliding limiting engagement. The limiting groove 11 can be used to limit the lifting and lowering process of the measuring pool 4, thereby ensuring that it can only lift and lower in the vertical direction.

[0036] Furthermore, there are multiple sets of water quality probes 7, which are evenly arranged and installed on the probe mounting base 8. The probe mounting base 8 described above enables reliable fixed installation of the water quality probes 7, thereby ensuring the reliability of their installation and fixation.

[0037] Furthermore, the fixed bracket 2 is equipped with a position sensor for detecting the lifting height of the measuring pool 4. This position sensor allows for control of the lowering height of the measuring pool 4 according to the needs of in-situ water quality monitoring.

[0038] Furthermore, the diameter of the water passage 6 is 5-10mm. This diameter ensures that water can flow normally while blocking impurities in the water, thus providing excellent protection for the water quality probe 7.

[0039] Furthermore, a rubber ring is provided between the top cover 5 and the measuring pool 4. The top cover 5 can be easily opened to remove the water quality probe 7 for maintenance or replacement.

[0040] Example 2:

[0041] The floating-type automatic water quality monitoring station with an external measuring pool provided in this embodiment operates as follows:

[0042] The fixing bracket 2 is secured to the side wall of the floating vessel body 1 by welding or flange bolt connection, ensuring the verticality of the vertical guide rail 3. The measuring pool 4 integrates water quality probes 7 for pH, DO, and conductivity, with a water passage hole 6 having a diameter of 5-10mm. The top cover 5 is waterproofed with a rubber ring. The measuring pool 4 is placed into the guide rail 3 through the limiting groove 11, and the slider connector is locked. Simultaneously, the winch device 9 is installed on the floating vessel station deck, with the winch rope passing through the fixed pulley 13 at the top of the guide rail and connecting to the measuring pool 4. This completes the installation of the device.

[0043] According to the needs of in-situ water quality monitoring, the measuring pool 4 is driven down to the target depth, such as 0.5m, 2m, or 3m, by the winch device 9. Alternatively, the measuring pool 4 can be driven down to the target depth by manual control of the winch device 9. After the water quality data is collected, the measuring pool 4 rises to the designated position to standby, reducing the impact of water flow, and periodically monitoring water quality data at different depths.

[0044] Example 3:

[0045] This embodiment provides a method for using an external measuring pool device for a floating automatic water quality monitoring station. The device is fixedly installed on the outside of the floating body 1. During the daily operation and maintenance of the automatic monitoring equipment, the measuring pool 4 is driven to the highest position by the winch device 9, the top cover 5 is opened, and the water quality probe 7 is removed for repair or replacement. The measuring pool is cleaned by flushing to remove algae and some small-diameter sediments, which are discharged through the water outlet 6, thus achieving effective cleaning of the measuring pool. In addition, the external protective net can be removed or cleaned to remove algae or shellfish attached to the outside of the measuring pool and around the water outlet, effectively increasing the service life of the probe and the convenience of operation and maintenance.

[0046] In summary, the floating automatic water quality monitoring station with external measuring pool provided by this utility model is fixed to the outside of the floating vessel body. The measuring pool integrates multi-parameter water quality probes and features an impact-resistant structure. Driven by a motor, the measuring pool vertically rises and falls along a guide rail within the fixed support range, enabling continuous monitoring of water quality at multiple depths within the length of the fixed support. It achieves one-time installation and multiple uses, with a simple, efficient, and quick operation process and flexible adjustable monitoring depth. Furthermore, the device is easy to install and maintain, employing a sliding rail snap-fit ​​connection, allowing a single person to disassemble and replace the entire measuring pool module. A quick-release top cover facilitates probe maintenance and replacement, as well as cleaning sediment within the pool, reducing maintenance complexity and effectively saving manpower and material costs. Compared to existing technologies, this device features strong probe protection, expanded monitoring dimensions, and convenient maintenance, making it particularly suitable for long-term in-situ monitoring of dynamic water bodies such as lakes and reservoirs.
