Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing equipment, specifically to a device for monitoring the turbidity of healthy water flow in river and lake ecosystems. Background Technology

[0002] Turbid water poses significant risks. It increases suspended solids, blocks sunlight, disrupts photosynthesis in aquatic plants, leading to their death and ultimately damaging the entire aquatic ecosystem's food chain. It also reduces dissolved oxygen levels, causing aquatic organisms to suffer from respiratory distress or even suffocation. Furthermore, turbid water may carry large amounts of pathogens, heavy metals, and other harmful substances, polluting drinking water sources, threatening human health, and affecting the quality of water used in industrial production. This reduces product quality, causes economic losses to related industries such as fisheries and tourism, and hinders sustainable socio-economic development.

[0003] Therefore, it is necessary to check the turbidity of the water to avoid water pollution.

[0004] Traditional water quality monitoring methods often employ periodic sampling and analysis. This method not only consumes a lot of manpower, resources, and time, but also, due to the long sampling intervals, it is easy to miss key information about water quality changes, making it impossible to comprehensively and accurately reflect the true dynamic changes in water quality.

[0005] To address the aforementioned issues, we propose a monitoring device for the turbidity of healthy water flow in river and lake ecosystems. Utility Model Content

[0006] The purpose of this invention is to provide a monitoring device for the turbidity of healthy water flow in river and lake ecosystems, in order to address the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device for the turbidity of healthy water flow in a river and lake ecosystem, comprising a telescopic sleeve, a first sleeve, and a second sleeve. The first sleeve and the second sleeve are located on the same side of the telescopic sleeve, with the first sleeve located directly below the second sleeve. A vertically upward infrared flashlight is fixedly installed on the inner wall of the first sleeve. A first lens is installed on the top inner wall of the first sleeve. A downward-facing infrared photosensitive sensor is fixedly installed on the top inner wall of the second sleeve. A second lens is installed on the bottom inner wall of the second sleeve.

[0008] Preferably, a slip ring is fixedly provided on one outer wall of the first sleeve and the second sleeve, the outer wall of the slip ring has a vertical guide groove, the outer wall of the telescopic sleeve is fixedly provided with a vertically downward guide rail, the outer wall of the slip ring and the inner wall of the telescopic sleeve are slidably connected, and the outer wall of the guide rail and the inner wall of the guide groove are slidably connected.

[0009] Preferably, a first threaded tube is fixedly provided on one side of the outer wall of the two slip rings through an opening, and a first fastening bolt is screwed onto the inner wall of the first threaded tube.

[0010] Preferably, a positioning cover is fixedly provided on one side of the outer wall of the first sleeve, a waterproof retarder motor is installed on the inner wall of the positioning cover, a rotating rod is fixedly provided through the top outer wall of the positioning cover at the output end of the waterproof retarder motor, a lever is fixedly provided on the outer wall of the rotating rod, a brush is adhered to the bottom outer wall of the lever, and the bottom outer wall of the brush is attached to the top outer wall of the first lens.

[0011] Preferably, the infrared flashlight, the infrared photosensitive sensor, and the waterproof slow motor are connected to a controller via wires. The controller is connected to a digital converter via wires, and the controller is also connected to a power plug via wires.

[0012] Preferably, the inner wall of the telescopic sleeve is slidably connected with an insert rod, and the bottom side wall of the telescopic sleeve is fixedly provided with a second threaded tube through an opening, and the inner wall of the second threaded tube is screwed with a second fastening bolt.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] After the present invention is inserted into the bottom of the water by the insertion rod, it can be fixed at the bottom of the water for a long time. It emits infrared light through the infrared flashlight. The light passes through the first lens and shines vertically upward toward the water surface and into the water flow. It will be refracted and scattered to different degrees depending on the amount of suspended particles in the water. The infrared photosensitive sensor converts the received light signal into an electrical signal and transmits the electrical signal to the controller, which can monitor the turbidity of the water at the bottom of the water at all times.

[0015] By analyzing this continuous monitoring data, researchers can gain a deeper understanding of the patterns and trends in river and lake water quality changes, promptly detect water quality anomalies such as sudden pollution incidents or abnormal fluctuations in the ecosystem, and thus take rapid and appropriate measures to respond and address them, effectively preventing further deterioration of water quality and protecting the health and stability of river and lake ecosystems.

[0032] Example 4

[0033] Based on Embodiment 1, in terms of electrical control, the infrared flashlight 4, the infrared photosensitive sensor 6, and the waterproof slow-speed motor 9 are connected to a controller via wires. The controller is used to receive signals from the infrared photosensitive sensor 6 and control the switching on and off of the infrared flashlight 4 and the start and stop of the waterproof slow-speed motor 9 according to a preset program. The controller is connected to a digital converter via wires, which is used to convert the analog signals output by the controller into digital signals for subsequent data processing and analysis. The controller is also connected to a power plug via wires for connecting to an external power source to provide power for this invention.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-5 By sliding the slip ring 14 on the outer wall of the first sleeve 2 and the second sleeve 3, the distance between the first sleeve 2 and the second sleeve 3 outside the telescopic sleeve 1 is controlled. After adjusting the distance between the first sleeve 2 and the second sleeve 3, the first fastening bolt 17 is tightened. Then, by adjusting the position of the insertion rod 20 inside the telescopic sleeve 1, the entire monitoring device is made to reach a length suitable for monitoring the target water depth. After that, the second fastening bolt 19 is tightened to fix the insertion rod 20. Then, the device is slowly inserted into the bottom of the water, with the first sleeve 2 and the second sleeve 3 in a suitable water flow monitoring position. The power plug is turned on to supply power to the entire monitoring device. The power is converted by the digital converter to provide stable power to the controller. The controller then controls the infrared flashlight 4 to turn on. The infrared flashlight 4 emits infrared light, which passes through the first lens 5 and is projected vertically upward toward the water surface and into the water flow. In the process of light refraction and scattering, the amount of suspended particles in the water affects the infrared light. When the water turbidity is high, there are more suspended particles, and a large amount of infrared light is refracted and scattered. As a result, less light reaches the second sleeve 3 and is processed by the second lens 7 before being received by the infrared photosensitive sensor 6. Conversely, when the water turbidity is low, there are fewer suspended particles, and the degree of refraction and scattering of infrared light is lower, allowing more light to reach the infrared photosensitive sensor 6. The infrared photosensitive sensor 6 converts the received light signal into an electrical signal and transmits it to the controller. After receiving the electrical signal, the controller analyzes and processes the signal according to a preset algorithm and program, comparing the intensity of the electrical signal with the preset range of electrical signal intensity corresponding to different turbidities to determine the current turbidity of the water flow.

[0036] After prolonged use, impurities may accumulate on the surface of the first lens 5, affecting the transmittance of infrared light and consequently the accuracy of the monitoring results. In this case, the controller will activate the waterproof slow-speed motor 9 according to the preset maintenance program. The waterproof slow-speed motor 9 drives the rotating rod 10, the lever 11, and the brush 12 to rotate. The brush 12 cleans the surface of the first lens 5, removing the attached scale or impurities, allowing infrared light to pass through the first lens 5 normally. After monitoring is completed, the controller can further process and store the monitored turbidity data through a digital converter. It can also transmit the data to external devices as needed, so that staff can conduct subsequent analysis and research, providing a scientific basis for the health assessment and management of river and lake ecosystems.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
