Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically a submerged water quality monitoring and sampling device with automatic sand removal and cleaning function. Background Technology

[0002] With the increasing sophistication of water resource protection and water environment management, the demand for water quality monitoring of natural water bodies is urgent, and the accuracy and continuity of monitoring data directly affect management decisions. Submerged water quality monitoring sampling devices, capable of obtaining accurate water samples from deep within the water body, have become core equipment for long-term field monitoring and are widely used in hydrological stations and environmental monitoring sites. However, existing devices face significant technical bottlenecks in complex water bodies, especially in rivers with high sediment content and areas with abundant floating debris. Their operational stability and sampling accuracy are greatly affected, with the main problems being as follows: First, sediment accumulation leads to sampling and equipment failure. After entering the device, sediment easily accumulates in the storage chamber, pipelines, and pumps, both contaminating the water sample and altering indicators such as turbidity, leading to data distortion, and also clogging pipelines, damaging pumps, shortening equipment lifespan, and increasing maintenance costs, making it difficult to meet long-term monitoring needs. Second, floating debris interferes with sampling. Leaves, aquatic plants, and other debris easily clog the sampling inlet and may also entangle the filter and pump, causing sampling interruptions; decaying debris can further introduce pollutants, contaminating the water sample. While existing devices are equipped with simple filters, they lack self-cleaning capabilities and require manual cleaning after clogging. Maintenance is difficult at remote sites or in severe weather, making it hard to guarantee continuous operation. Thirdly, manual maintenance is costly and limited. Existing solutions rely on manual inspection, cleaning, and component replacement. Field sites are remote and difficult to access, resulting in high inspection costs. Maintenance under high water levels or in severe weather poses safety risks, and device shutdown during maintenance leads to data gaps. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a submerged water quality monitoring and sampling device with automatic sand removal and cleaning functions.

[0018] 1.

[0024] 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.

[0025] Example 1:

[0026] like Figures 1 to 2 As shown in the figure, the submerged water quality monitoring and sampling device with automatic sand removal and cleaning function provided in this embodiment includes a water storage tank 1, a float 2 is provided inside the water storage tank 1, a float ring 10 is fitted on the top of the outer ring of the float 2, and a sliding rod assembly is provided inside the float 2.

[0027] Understandable Figure 1 The diagram only schematically illustrates some of the components of the water quality monitoring sampling device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, water quality monitoring sampling devices can also include, compared to... Figure 1 More or fewer parts.

[0028] In this embodiment, the float 2 is used for preliminary filtration and sediment separation of water samples, suitable for sampling in shallow water bodies less than 0.3 meters deep. The float ring 10 at the top of the outer ring of the float 2 can move the float 2 up and down with changes in water level, ensuring that the inlet 3 is always at a suitable water level and avoiding sampling interruptions caused by water level fluctuations. The sliding rod assembly inside the float 2 provides guidance for the up and down movement of the float 2, preventing the float 2 from deviating and affecting the accuracy of the sampling position. The water storage tank 1 and the float 2 work together to ensure that the entire sampling process can be carried out continuously, avoiding interruptions or contamination of water samples during transmission.

[0029] Specifically, the upper end of the float 2 is provided with a water inlet 3, and a net 4 is fixed to the water inlet 3 by screws.

[0030] In this embodiment, the inlet 3 at the upper end of the float 2 is the main channel for water to enter the float 2. Its orientation is consistent with the upstream water flow direction, allowing water to flow smoothly into the interior of the float 2. A barrier net 4, fixed to the inlet 3 with screws, can intercept debris such as leaves, weeds, and gravel in the water, preventing these debris from entering the float 2 and clogging subsequent filtration structures or sampling pipelines, thereby reducing the possibility of device malfunction. The barrier net 4 is fixed with screws, allowing it to be removed for cleaning or replacement at any time, preventing debris from accumulating on the net surface and affecting water flow efficiency. Furthermore, the disassembly and assembly process requires no special tools, and on-site personnel can complete the operation, reducing the difficulty of daily maintenance.

[0031] Specifically, a filter plate 5 is installed inside the float 2.

[0032] As a preferred implementation, the filter plate 5 inside the float 2 is used to filter the river water entering the float 2, which can intercept some sediment particles, reducing the sediment content in subsequent water samples. The pore size of the filter plate 5 is set according to the common particle size of sediment in shallow water, which can effectively filter sediment without excessively obstructing the water flow into the float 2, ensuring that the water level inside the float 2 changes synchronously with the water level of the external water body, maintaining a stable sampling state. Preliminary filtration can reduce the wear of sediment on the water sampling pump, extend the service life of the water sampling pump; at the same time, it can also reduce the amount of sediment settling in the subsequent water storage stage, reduce the frequency of silt removal operations, improve the overall operating efficiency of the device, ensure the clarity of the final collected water sample, and make the water sample more representative.

[0033] Specifically, the float 2 is funnel-shaped, and a water pipe 8 is connected to the bottom of the float 2.

[0034] It should be noted that the float 2 adopts a funnel-shaped structure with a converging bottom, allowing the sediment not trapped by the filter plate 5 to naturally settle to the bottom of the float 2, preventing sediment from accumulating and occupying effective space. The water pipe 8 connected to the bottom of the float 2 can promptly discharge the settled sediment, achieving automatic sediment removal, reducing the workload of manual cleaning, and lowering on-site maintenance costs. The funnel-shaped structure accelerates the convergence of sediment to the bottom, and combined with the pumping action of the water pipe 8, it quickly removes sediment from the float 2, preventing sediment from stagnating and reducing the effective volume, ensuring the float 2 can continuously and stably perform its sampling pretreatment function.

[0035] Specifically, a sampling pipe 6 is installed between the float 2 and the water storage tank 1. One end of the sampling pipe 6 is connected to the lower end of the float 2, and the other end of the sampling pipe 6 is positioned above the water surface. The sampling pipe 6 is connected to a water pump.

[0036] As a preferred implementation method, the water intake position of sampling tube 6 avoids the sediment deposition area at the bottom of float 2, ensuring that the collected sample is the supernatant that has undergone preliminary filtration and settling, thereby improving the purity of the water sample and reducing the interference of sediment on subsequent test results. Sampling tube 6 is sealed to prevent the water sample from coming into contact with external contaminants during transmission, ensuring the scientific validity of the water sample and meeting the stringent requirements for sampling accuracy in water quality monitoring.

[0037] Example 2:

[0038] Specifically, the float 2 is fixedly installed above the bottom of the water storage tank 1 by the float fixing seat 7.

[0039] It should be noted that the float 2 is installed above the bottom of the water storage tank 1 through the float fixing seat 7. The fixing seat can restrict the horizontal movement of the float 2, avoid the float 2 from shifting due to water flow impact, ensure that the water inlet 3 is always aligned with the upstream water direction, maintain a stable water intake state, and make the float 2 less likely to tip over under the action of water flow. Especially in the slight water flow disturbance that may exist in shallow water, it can maintain the overall structural stability of the float 2, avoid the failure of filtering, sand removal and other functions due to the tilting of the float 2, and ensure that the sampling process is carried out normally.

[0040] Specifically, the water storage tank 1 is oval-shaped, and a second water pipe 9 is installed above the bottom of the water storage tank 1. Both the second water pipe 9 and the first water pipe 8 are connected to the water pump.

[0041] In this embodiment, the water storage tank 1 adopts an elliptical structure, which is more conducive to the concentrated settling of silt at the bottom compared to a circular structure, reducing the amount of silt adhering to the tank wall and lowering the difficulty of subsequent cleaning. Water pipe 2 (9) and water pipe 1 (8) are both connected to a water pump at the bottom of the water storage tank 1. Water pipe 2 (9) is used to extract the silt settled at the bottom of the water storage tank 1, realizing automatic silt removal from the water storage tank 1; water pipe 1 (8) is responsible for discharging the silt from the bottom of the float 2. The two work together to complete the automatic sand removal and cleaning operation of the entire device.

[0042] During use, the outer float ring 10 of the float 2, in conjunction with the internal sliding rod assembly, achieves adaptive water level adjustment to ensure stable water intake at the inlet. The water first passes through the inlet 3 and the net 4 to intercept large debris, and then passes through the filter plate 5 inside the float 2 to retain most of the silt. Subsequently, the funnel-shaped float 2 guides the remaining silt to converge at the bottom, and the elliptical water storage tank 1 settles the fluctuating water and silt. The water pump extracts the supernatant through the sampling pipe to ensure the scientific validity of the water sample. After sampling, the water pump switches modes and discharges the settled silt through the bottom water pipe 1 of the float and the bottom water pipe 2 of the water storage tank, achieving automatic sand removal and cleaning, greatly reducing manual maintenance and avoiding gaps and distortions in monitoring data.

[0043] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
