Description

Technical Field

[0001] This utility model relates to the field of river and lake water quality monitoring, specifically to an online monitoring device for in-situ water quality stratification in rivers and lakes. Background Technology

[0002] With the rapid development of the national economy and society, the continuous improvement of industrialization, and the gradual emergence of ecological and environmental problems, the urbanization process has accelerated significantly, and the total amount of sewage discharge has continued to increase. People are paying increasing attention to the water pollution of rivers and lakes, and accelerating the restoration and protection of river and lake water environments is one of the key tasks in my country at present. River and lake water environment restoration is a long-term and complex process. Studies have shown that changes in environmental conditions can significantly affect the effectiveness of water environment management projects. Therefore, carrying out water environment restoration and monitoring, improving water quality conditions, understanding the migration and change patterns of pollutants, and timely evaluating the water quality of rivers and lakes can provide reliable technical support for current management work such as water resource utilization, water environment protection, and water pollution control.

[0003] Currently, online water environment monitoring mainly includes two types: automatic monitoring and manual sampling monitoring. Due to limitations in timeliness and safety, manual sampling has been gradually replaced by automatic monitoring, except for specific indicators. Automatic monitoring is convenient and timely, and is widely used in water quality monitoring of lakes and rivers. However, automatic monitoring requires a stable power supply; for lakes and rivers, ensuring a stable and continuous power supply to the automatic monitoring devices is a crucial issue. Furthermore, automatic monitoring enables high-frequency data acquisition. Currently, the commonly used data export method is mainly through copying, which is time-consuming and laborious. Therefore, there is an urgent need for a simple and practical data transmission method to achieve the export and simple analysis of automatic monitoring data.

[0004] In actual monitoring, the water levels of rivers and lakes constantly change due to environmental conditions and hydrological and hydrodynamic factors. Especially in current river and lake management projects, certain technical means are often required to dynamically control water levels in order to achieve environmental restoration. During the flood and dry seasons, significant differences in water levels occur in lakes and rivers, with some areas experiencing differences exceeding 1 meter. Simultaneously, pollutants continuously diffuse and dissolve in the water, resulting in uneven concentrations of pollutants in rivers and lakes. Water quality varies not only in the planar dimension but also along depth, particularly in deep waters with high temperature differences and complex flow patterns. All these factors significantly impact water quality monitoring results. Existing water quality monitoring equipment primarily targets the surface water of rivers and lakes, and its monitoring depth cannot be arbitrarily changed, failing to meet the practical needs of stratified sampling at different depths along the sampling vertical in complex water environments. Therefore, improvements are needed to achieve accurate water quality monitoring under drastically changing water levels and to meet the requirements of stratified water quality monitoring.

[0040] Please see Figure 1 For example, an online monitoring device for in-situ water quality stratification in rivers and lakes includes:

[0041] Positioning pile 14, the lower end of which is inserted into the bottom mud of the water body and the upper end extends out of the water surface, and a floating slider 15 is movably sleeved on the outer surface of the positioning pile 14;

[0042] An ecological floating bed 11 is floated on the water surface, and the ecological floating bed 11 is flexibly connected to the floating slider 15;

[0043] The energy component includes a photovoltaic panel 21 and an energy storage component 22. The photovoltaic panel 21 is fixedly installed on the top of the positioning pile 14 to convert light energy into electrical energy. The energy storage component 22 is electrically connected to the photovoltaic panel 21 to provide power to each device.

[0044] The water quality monitoring device 33 and the displacement mechanism are fixedly installed on the ecological floating bed 11 or the floating slider. The displacement mechanism is at least partially located below the water surface. The displacement mechanism drives the water quality monitoring device 33 to rise or fall along the sampling vertical direction.

[0045] During monitoring, the photovoltaic panel 21 provides energy to various electrical devices through the energy storage component 22. The water quality monitoring device 33 uses the river and lake surface as a reference plane and monitors the changes in water quality values ​​at different water levels by rising or falling through a displacement mechanism. The water quality monitoring device 33 uploads the monitored water quality data to the cloud through a signal generator for users to view and download. The water quality information of multiple monitoring points on the monitoring vertical line is collected in sequence. After the collection is completed, the displacement mechanism drives the water quality monitoring device to rise vertically away from the water surface to avoid damage to the equipment due to long-term immersion.

[0046] The aforementioned in-situ stratified online water quality monitoring device for rivers and lakes integrates the water quality monitoring device 33 with the ecological floating bed 11 or a floating slider via a displacement mechanism. This ensures that the relative distance between the water quality monitoring device 33 and the water surface remains constant in the initial state, preventing the sampling points from changing with water level fluctuations. This guarantees long-term monitoring of river water quality changes under the restoration of the ecological floating bed 11. A photovoltaic panel 21 at the top of the positioning pile 14 provides power to the electrical equipment. The flexible connection between the positioning pile 14 and the ecological floating bed 11 prevents significant displacement of the floating bed and avoids inconsistencies between the ecological floating bed 11 and the river / lake water level due to the positioning pile 14. The displacement mechanism enables stratified monitoring by the water quality monitoring device 33, providing a more comprehensive understanding of water quality changes.

[0047] In one embodiment, the ecological floating bed 11 is connected to the floating slider 15 on the positioning pile 14 by a metal chain. The floating slider 15 is a hollow sleeve structure with a diameter of DN50 to 90, which is fitted around the positioning pile 14. The floating slider 15 is provided with multiple buckles for connecting with the metal chain of the floating bed platform. When the water level changes, the floating slider 15, as a sliding structure with a certain buoyancy, will rise or fall with the change of water level. Therefore, when the water level changes and causes the floating bed platform to rise or sink, the floating slider 15 can also slide up and down with the floating bed platform to ensure that the floating bed platform is flush with the current actual water surface.

[0048] In one embodiment, the positioning pile 14 is located in the hollow area in the middle of the ecological floating bed 11. The large ecological floating bed 11 is placed around the positioning pile 14 to prevent it from being inconspicuous and colliding with passing ships. The positioning pile 14 has a hollow internal structure, made of waterproof and rust-resistant materials such as stainless steel or galvanized steel pipe, with pipe sizes ranging from DN40 to 80. The external power cord is housed within this structure to reduce erosion from river and lake water and rainwater. A limiter 35 is also fixedly installed at the lower end of the positioning pile 14 to restrict the displacement of the floating body slider 15, preventing the ecological floating bed 11 from running aground.

[0049] In one embodiment, the ecological floating bed 11 platform has a modular structure with a shell made of PP material and an interior that can be filled with foam board or other materials with high buoyancy. The structure can be divided into modules according to actual needs, and the size of each module can be changed arbitrarily to facilitate splicing. However, the overall structure must be centrally symmetrical to avoid overturning due to instability.

[0050] Please refer to it again. Figure 1 The ecological floating bed 11 is circular in shape and has a centrally symmetrical structure. The floating plate of the ecological floating bed 11 is made of PP material with a thickness of 8-15 μm. The bottom of the ecological floating bed 11 is flat, and the top is sloping with an inclination angle of 15-30°. Figure 2As shown, the top of the ecological floating bed 11 is arranged with several planting areas 13 and several photovoltaic areas 12 along the circumferential direction. The planting areas 13 are used for planting plants. Each planting area 13 has a pile, and each pile is connected to the floating slider 15 by a metal chain to ensure that the floating slider 15 is subjected to uniform force. The photovoltaic areas 12 are used to convert solar energy into electrical energy. The planting areas 13 are adjacent to and alternate with the photovoltaic areas 12. The planting areas 13 are arranged on the surface of the ecological floating bed 11 at intervals, dividing the top of the ecological floating bed 11 into several equal-sized parts. The weight of each part may vary, but it needs to be centrally symmetrical to ensure stability. Small holes with a diameter of 2-4 cm are provided on the bottom floating plate of the planting area 13. The lower layer of the planting area 13 is a gravel layer with a diameter of 4-6 cm and a thickness of 2-4 cm. The upper layer of the planting area 13 is a clay layer with a thickness of 2-4 cm. The surface of the photovoltaic zone 12 is used to attach photovoltaic panels. The planting zone 13 intersects with the photovoltaic zone 12. When splicing, a water guide channel is provided at the splicing point. The floating bed is equipped with a suspension belt 16. When the overall volume of the ecological floating bed 11 is small and the area has large wind and waves, heavy objects can be suspended on the suspension belt 16 to improve the overall stability.

[0051] In one embodiment, the energy storage component 22 is a solar charge-discharge converter and an energy storage device. The modular photovoltaic panels are independent of each other and are each connected to the solar charge-discharge converter and the energy storage device, reducing the problem of automatic monitoring equipment malfunction due to damage to individual photovoltaic panels. The solar charge-discharge converter and the energy storage device are mounted on the positioning pile 14 and located below the photovoltaic panels. The photovoltaic panels on top of the positioning pile 14 can prevent external interference to the solar charge-discharge converter and the energy storage device while they are being charged.

[0052] In one embodiment, the in-situ water quality stratification online monitoring device for rivers and lakes further includes a wireless signal generator 34. The water quality monitoring device 33 uploads the monitored water quality data to the cloud through the wireless signal generator 34. The wireless signal generator 34 stores the data information read by the water quality monitoring device 33 to the cloud in real time through wireless signals, avoiding the problem of information loss or the need for manual on-site reading.

[0053] like Figure 4As shown, in one embodiment, the displacement mechanism is a telescopic device. The fixed end of the telescopic device is fixed to the side wall of the ecological floating bed 11 or the floating slider 15, and the movable end of the telescopic device is positioned facing the water surface to extend into the water. The movable end of the telescopic device is also fixedly connected to the water quality monitoring device 33. In another embodiment, the displacement mechanism includes a traction component and a lead screw. The lead screw is connected to the ecological floating bed 11 or the floating slider 15 via a bracket. The bracket is fixedly mounted on the ecological floating bed 11 or the floating slider 15, and its end extends into the water. The lead screw is rotatably mounted on the bracket and is vertically positioned. The traction component is a stepper motor, and a carrier is screwed to the outer surface of the lead screw. The carrier is fixedly connected to the water quality monitoring device 33. The stepper motor drives the lead screw to rotate, causing the water quality monitoring device 33 to rise or fall on the lead screw, thereby allowing the water quality monitoring device 33 to detect at different water levels.

[0054] Please see Figure 3 The water quality monitoring device 33 has a built-in probe, which includes various water quality monitoring probes. The housing 37 of the water quality monitoring device 33 is provided with a light-transmitting window 38 to facilitate the improvement of the accuracy of optical monitoring methods.

[0055] In one embodiment, to avoid insufficient energy supply to the energy storage component 22 due to continuous rainy weather, a storage battery is also installed on the ecological floating bed 11. The storage battery is equipped with a waterproof cover and is connected to the energy storage component 22. The storage battery is used to connect to various electrical devices. When the power is sufficient, the storage battery stores electrical energy as a backup power source.

[0056] Please see Figure 5 In one embodiment, the in-situ water quality stratification online monitoring device for rivers and lakes further includes a vision system and an information feedback analysis system. The vision system includes an underwater monitoring camera 31 and a light source supply device 32. The underwater monitoring camera 31 is used to detect the growth of plants at the bottom of the water and can provide feedback to the information feedback analysis system based on the plant growth and light source conditions monitored at the bottom. After receiving the information, the information feedback analysis system analyzes and makes decisions, and provides light source for bottom water quality monitoring and plant growth through the light source supply device 32 as needed.

[0057] The above description of the embodiments is provided to enable those skilled in the art to understand and use the present invention. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
