Description

Technical Field

[0001] The invention belongs to the technical field of water quality detection, in particular to a water quality detection device for water pollution control. Background Art

[0002] Water is the source of life, and the quality of water directly affects human health, ecosystem balance, and social and economic development. With the rapid development of social economy and the acceleration of urbanization and industrialization, water shortage and water pollution are becoming increasingly serious. People's requirements for the quality of drinking water are constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly. This demand has promoted the continuous advancement of water quality testing technology.

[0003] In recent years, water quality monitoring technology has made significant progress. A variety of physical, chemical and biological methods are widely used in water quality testing. The maturity of these technologies provides a technical basis for the research and development of water quality testing equipment. In different application scenarios, water quality testing equipment needs to meet different needs.

[0004] Existing water quality detection equipment usually uses water pumps or motors to drive the collection of water. Although such equipment has shown corresponding advantages in improving detection efficiency, it also has some shortcomings. When collecting water, such equipment needs to consume a certain amount of electricity or other energy. Mechanical parts such as water pumps and motors are prone to wear and aging after long-term operation. They need to be regularly maintained and replaced, which increases the cost of use. Therefore, it is necessary to propose a water quality detection device for water pollution control. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a water quality detection equipment for water pollution control, which detects the turbidity of water by light reflection, avoids the use of water pumps and motors, reduces energy utilization, reduces the frequency of equipment maintenance, and thus reduces the maintenance cost of the equipment.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a water quality detection device for water pollution control, comprising a detection system and a detection component, the detection system is connected to the detection component by signal; the detection component comprises a reflection cavity and a detection cavity, the detection cavity is fixedly connected to the outside of the reflection cavity, and the detection cavity is used to detect the water quality information of the water body; a convex lens is fixedly connected to the top of the reflection cavity, and a plurality of reflection plates are fixedly connected to the inner wall of the reflection cavity, and the reflection plates are staggered; receiving components for receiving reflected light are provided between adjacent reflection plates; an opening is provided at the bottom of the reflection cavity, and a filtering component for filtering particulate matter is provided at the opening.

[0007] The principle of the basic solution is: the particulate matter in the water is removed by the filter assembly at the bottom of the reflective cavity, and then the water enters the reflective cavity due to its negative pressure environment. When the external light source shines on the convex lens, the external light source will be further concentrated, and then enter the reflective cavity.

[0008] In the reflective cavity, when the external light source passes through the water, the suspended matter in the water will scatter the light. After the light is scattered, it passes through the reflective plates and receiving components staggered in the reflective cavity, so that the light is reflected and focused multiple times to improve the detection accuracy. The receiving component receives the light signal and converts it into an electrical signal, which is analyzed and processed by the detection system to obtain relevant information about the pollutants in the water.

[0009] The beneficial effects of the basic scheme are: 1. This device uses an external light source that emits natural light, a convex lens and staggered reflective plates to achieve multiple reflections and focusing of light, which can effectively increase the path length of light in the water sample and the intensity of the light signal, thereby improving the detection accuracy. The application of this optical principle enables the device to more accurately capture the characteristic information of pollutants in the water.

[0010] 2. This device detects the turbidity of water through light reflection, avoiding the use of water pumps and motors, reducing energy utilization, reducing the frequency of equipment maintenance, and thus reducing the maintenance cost of the equipment; increasing the durability of the equipment, in line with the goal of sustainable development.

[0011] 3. This detection method is non-destructive to water bodies, can better preserve the original samples, and has little impact on the environment. By combining the detection system with wireless communication, remote data transmission is realized, which is convenient for environmental managers and scientific researchers to obtain water quality information anytime and anywhere, and conduct remote monitoring and data analysis.

[0012] Furthermore, the receiving component includes a photoelectric converter, and the detection system is used to receive the photoelectric converter signal; the photoelectric converter is fixedly connected to the inner wall of the reflective cavity, and the photoelectric converter is located between adjacent reflective plates; the photoelectric converter is electrically connected to a battery, and the battery is fixedly connected to the outside of the reflective cavity.

[0013] The beneficial effect of the basic solution is that when scattered light or reflected light reaches the photoelectric converter, the photon energy will be converted into electron transition, resulting in changes in current or voltage, and the received light signal will be converted into an electrical signal. Its installation position corresponds to the reflector, which can maximize the reception of light scattered or reflected from the water body, further increase the light collection efficiency, and thus improve the sensitivity of turbidity detection.

[0014] Furthermore, the filter assembly includes a filter plate, which is detachably connected to the bottom of the reflective cavity; the filter plate material is selected from one or more of quartz sand, ceramsite, sponge, coarse sand and gravel.

[0015] The beneficial effects of the basic solution are: the filter plate can effectively intercept and absorb large particles of impurities in the water sample, such as sediment, algae, plant debris, etc., reduce the interference of these substances on light scattering, and increase the accuracy of turbidity detection. It can effectively protect the core components of the detection equipment and reduce mechanical wear and performance degradation caused by particle accumulation.

[0016] Furthermore, the surfaces of the reflective plates are fixedly connected with reflective materials, and the reflective materials are selected from one or more of reflective films, reflective cloths, reflective lattices and reflective coatings.

[0017] The beneficial effects of the basic solution are: the reflective plate can combine several materials through fixedly connected reflective materials to achieve the refraction effect of different light sources, can adapt to various detection environments and application scenarios, can efficiently reflect light back into the water, and increase the number of interactions between light and suspended matter in the water.

[0018] Furthermore, a light source transmitter is detachably connected to one end of the reflective cavity near the convex lens. The light source transmitter includes a laser diode. The laser diode is electrically connected to a battery. The detection system is used to control the operation of the laser diode.

[0019] The beneficial effect of the basic solution is: when it is cloudy or in the evening when the light source is insufficient, you can choose to install the light source transmitter on the top of the reflective cavity, and then transmit the light source of the laser diode through a convex lens. The laser diode can adjust the intensity and frequency of the light according to the different concentrations of suspended matter. When the reflected light is weak, it means that the concentration of suspended matter is high, and the light intensity can be further increased; when the reflected light is strong, it means that the concentration of suspended matter is low, and the current light intensity can be retained or adjusted down appropriately. This enables the equipment to adapt to a wider range of detection environments and water sample types, improving the flexibility and application range of the equipment.

[0020] Furthermore, the detection cavity includes a plurality of detection chambers, adjacent detection chambers are fixedly connected, the bottom of the inner wall of the detection chamber is respectively fixedly connected with a pH sensor, a conductivity sensor, a dissolved oxygen sensor and a heavy metal sensor, and the detection system is used to receive signals from the pH sensor, the conductivity sensor, the dissolved oxygen sensor and the heavy metal sensor;

[0021] The bottom of the detection chamber is connected to a water outlet, and the output end of the water outlet is removably connected with a plug cover; the width of the detection chamber increases from left to right; a number of M-shaped straws are embedded and installed at the connection between the detection chamber and the reflection cavity, the height of the input end of the M-shaped straw is lower than the height of the output end, and the detection chamber and the reflection cavity are connected to each other through the M-shaped straw.

[0022] The beneficial effects of the basic scheme are as follows: when water flows into the reflection cavity, due to the special design of the M-shaped straw and the placement position of the input end of the M-shaped straw is lower than the output end, the M-shaped straw is placed at an angle, and the vertex close to the input end will be lower than the vertex close to the output end, so when the water level rises to the lower vertex of the M-shaped pipette for the first time, the water will be forced to turn and fall, and this falling process is an accelerated motion process under gravity operation; at this time, the speed of the water flow will become faster and faster, forming a certain impact force; when the water flows to the turning point at the bottom of the M-shaped straw, it will continue to pass the highest point of the M-shaped straw upwards due to the impact force, and then flow downward after passing the highest point of the M-shaped straw, and thus flow to the output end of the M-shaped straw; and due to the cohesive force of water, the water will continue to be transported to the output end of the M-shaped straw until the water level is lower than the output end of the M-shaped straw, and then the flow stops.

[0023] In this way, water can be transported to the detection chamber. Compared with the traditional method of using a water pump for transmission, it does not require additional power drive and relies entirely on gravity, so it has advantages in energy consumption. In addition, this method of smoothly transmitting water can reduce bubbles and turbulence in the water, further ensuring the accuracy and stability of each sensor reading. The pH sensor, conductivity sensor, dissolved oxygen sensor and heavy metal sensor can detect the pH value, conductivity, dissolved oxygen concentration and heavy metal ion content of the water, respectively, and provide comprehensive water quality information.

[0024] At the same time, multiple parameters in the water sample are independently tested. The sensor in each test chamber focuses on a specific water quality parameter, reducing mutual interference between parameters and improving the accuracy and reliability of the test. In addition, the width of the test chamber increases from left to right, which can effectively control the liquid level difference between each test chamber.

[0025] Furthermore, the output ends of the M-type straws are all connected to solenoid valves, and the detection system is used to control the operation of the solenoid valves; the M-type straws are distributed at equal intervals, and the number of installed M-type straws decreases from left to right; a number of partitions are bolted and connected in the detection chamber, and the partitions are all located above the output ends of the M-type straws adjacent to them; the partitions are all provided with leakage holes, and the leakage holes are all connected to one-way valves.

[0026] The beneficial effect of the basic scheme is: because the M-shaped straws are evenly spaced in the detection chamber, and partitions are installed above the output ends of the M-shaped straws, the corresponding capacities between adjacent partitions are equal. In each detection chamber, the water capacity corresponding to a scale value between adjacent partitions, combined with the corresponding sensor in the detection chamber, can obtain the water with the corresponding capacity according to actual needs. Each M-shaped straw is connected to a specific detection chamber. When the sample detection and sampling of one layer of water is completed, the corresponding solenoid valve is closed, and then the sample of the next layer of water is detected and sampled, so as to realize the detection and sampling of water samples at different depths. After the water is taken, it can be taken out from the outlet.

[0027] Through this precise detection and sampling method, it is possible to ensure that the water volume used for each test is consistent, and collect water samples at different depths, thereby reducing the capacity error that may be caused by traditional manual sampling. According to different detection requirements, the opening of the solenoid valve can be flexibly adjusted to obtain the water volume of the corresponding concentration value to meet the needs of various detection projects.

[0028] Furthermore, the inner top wall of the detection chamber is detachably connected with a gas adsorption plate, and the material of the gas adsorption plate is selected from one or more of activated carbon, silica gel, molecular sieve, porous ceramic and nano mineral crystal.

[0029] The beneficial effect of the basic scheme is that the design of the gas adsorption plate can determine whether there is odor or pollution in the water body, based on the high affinity and adsorption capacity of the adsorption material for specific pollutants. When the water body contains volatile organic compounds (VOCs), ammonia, hydrogen sulfide and other gases that may produce odor or indicate the presence of pollution, these gas molecules will be adsorbed on the gas adsorption plate, and by detecting the changes in the adsorbed substances on the adsorption plate, the pollution status of the water body can be indirectly determined.

[0030] Furthermore, a telescopic rod is fixedly connected to the outer side of the top of the detection cavity, and the telescopic rod includes a first rod and a second rod. The first rod is slidably matched with the inner wall of the second rod; the side of the first rod away from the detection cavity is rotationally matched with a limiting bolt.

[0031] The beneficial effects of the basic scheme are as follows: the telescopic rod is composed of two sections, and a sliding fit is adopted between the first rod and the second rod, allowing the first rod to be telescoped inside the second rod, thereby changing the overall length. The function of the limit bolt is to fix the telescopic rod by tightening the limit bolt after it is adjusted to the required length, to prevent accidental expansion or contraction due to external forces during use, and to ensure the stable positioning of the detection equipment in the water body. The adjustability of the telescopic rod enables the detection equipment to flexibly adapt to water bodies of different depths, ensuring the representativeness of the detection point.

[0032] Further, the detection system includes a data collection module, a data transmission module, a data analysis module, a control module and an early warning module;

[0033] A data collection module is used to collect water quality information, including pH value, conductivity, dissolved oxygen concentration, heavy metal ion content and turbidity information;

[0034] A data transmission module, used to transmit the collected water quality information to the detection system via wireless transmission;

[0035] The data analysis module is used to analyze and mine water quality information after receiving it, extract key information, and provide processing solutions based on the key information;

[0036] A control module for controlling the operation of the laser diode and the solenoid valve in the device;

[0037] Early warning module, when the water quality information exceeds the preset threshold, the early warning module automatically sends an early warning signal to the detection system through wireless transmission.

[0038] The beneficial effects of the basic scheme are: through the mutual cooperation between the modules, the detection system is automatically controlled, and the water quality changes are discovered in time. Once the water quality information exceeds the safe range, the early warning module will immediately issue an alarm to ensure rapid response and reduce the expansion of environmental pollution. Through data analysis and processing, algorithms and models are used to analyze data, identify patterns, and formulate effective pollution control strategies based on accurate water quality data to maintain the ecological balance of water bodies.

[0042] The figure marks in the drawings of the specification include: reflection cavity 1, detection cavity 2, convex lens 3, reflection plate 4, photoelectric converter 5, battery 6, filter plate 7, laser diode 8, plug cover 9, M-shaped straw 10, solenoid valve 11, gas adsorption plate 12, telescopic rod 13, limit bolt 14, partition 15, and one-way valve 16. DETAILED DESCRIPTION

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1: basically as attached Figure 1-Figure 3As shown: A water quality detection device for water pollution control includes a detection system and a detection component, the detection system is connected to the detection component by signal; the detection component includes a reflection cavity 1 and a detection cavity 2, the detection cavity 2 is fixedly welded to the outside of the reflection cavity 1, and the detection cavity 2 is used to detect water quality information of the water body.

[0045] A convex lens 3 is fixedly bonded to the top of the reflective cavity 1, and a plurality of reflective plates 4 are fixedly bonded to the inner wall of the reflective cavity 1, and the reflective plates 4 are staggeredly distributed; reflective materials are fixedly bonded to the surfaces of the reflective plates 4, and the reflective materials are selected from one or more of reflective films, reflective cloths, reflective lattices and reflective paints. In this embodiment, reflective paints are selected.

[0046] First, the light is gathered by the convex lens 3, and then the fixed reflective paint can efficiently reflect the light back into the water, increasing the number of interactions between the light and the suspended matter in the water. It can respond more sensitively to changes in suspended matter in the water and provide reliable detection results even under slight turbidity fluctuations.

[0047] A receiving assembly for receiving reflected light is installed between adjacent reflective plates 4. The receiving assembly includes a photoelectric converter 5, and the detection system is used to receive the signal of the photoelectric converter 5; the photoelectric converter 5 is screwed and fixedly connected to the inner wall of the reflective cavity 1, and the photoelectric converter 5 is located between adjacent reflective plates 4; the photoelectric converter 5 is electrically connected to a battery 6, and the battery 6 is bolted and fixedly connected to the outside of the reflective cavity 1. When scattered light or reflected light reaches the photoelectric converter 5, the photon energy will be converted into an electron transition, generating a change in current or voltage, and converting the received light signal into an electrical signal. Its installation position corresponds to the reflective plate 4, which can maximize the reception of light scattered or reflected from the water body, further increase the light collection efficiency, and thus improve the sensitivity of turbidity detection.

[0048] The bottom of the reflective cavity 1 is provided with an opening, and a filter assembly for filtering particulate matter is provided at the opening. The filter assembly includes a filter plate 7, and the filter plate 7 is threadedly connected to the bottom of the reflective cavity 1; the material of the filter plate 7 is selected from one or more of quartz sand, ceramsite, sponge, coarse sand and gravel, and quartz sand is selected in this embodiment. The filter plate 7 can effectively intercept and adsorb large particles of impurities in the water sample, such as mud, algae, plant debris, etc. Reduce the interference of these substances on light scattering and increase the accuracy of turbidity detection. It can effectively protect the core components of the detection equipment, reduce mechanical wear and performance degradation caused by the accumulation of particulate matter, reduce the frequency of regular cleaning or replacement, reduce maintenance costs and workload, and thus extend the service life of the equipment.

[0049] The specific implementation process is as follows: first, when the device is in use, the device is placed in the area to be detected, and the particles in the water are removed through the filter plate 7 provided at the bottom of the reflective cavity 1, and then the water enters the reflective cavity 1 due to its negative pressure environment. When the external light source is irradiated on the convex lens 3, due to the special design of the convex lens 3, the external light source will be further concentrated, and then enter the reflective cavity 1 after being concentrated.

[0050] In the reflective cavity 1, when the external light source passes through the water, the suspended matter in the water will scatter the light. There are two main types of scattering. When the size of the suspended matter is much smaller than the wavelength of light, the scattering follows the Rayleigh scattering law, and the intensity of the scattered light is inversely proportional to the fourth power of the wavelength; when the size of the suspended matter is close to or larger than the wavelength of light, the scattering follows the more complex Mie scattering law. At this time, the intensity distribution of the scattered light is related to the size, shape and refractive index of the suspended matter. After the light is scattered, it passes through the reflective plates 4 and the photoelectric converter 5 that are staggered in the reflective cavity 1, so that the light is reflected and focused multiple times to improve the detection accuracy. The photoelectric converter 5 receives the light signal and converts it into an electrical signal, which is analyzed and processed by the detection system to obtain relevant information about pollutants in the water.

[0051] This device detects the turbidity of water through light reflection, avoiding the use of water pumps and motors, reducing energy use, reducing the frequency of equipment maintenance, and thus reducing the maintenance cost of the equipment; increasing the durability of the equipment, in line with the goal of sustainable development. This detection method is non-destructive to the water body, can better preserve the original water sample, and has little impact on the environment. By combining the detection system with wireless communication, remote data transmission is achieved, which makes it easy for environmental managers and scientific researchers to obtain water quality information anytime and anywhere, and conduct remote monitoring and data analysis.

[0052] Embodiment 2:

[0053] The difference from the above embodiment is that a light source emitter is snap-connected to one end of the reflective cavity 1 close to the convex lens 3 , the light source emitter includes a laser diode 8 , the laser diode 8 is electrically connected to the battery 6 , and the detection system is used to control the operation of the laser diode 8 .

[0054] The specific implementation process is as follows: When it is cloudy or in the evening when the light source is insufficient, the laser diode 8 of the light source transmitter can be installed on the top of the reflective cavity 1, and then the light source of the laser diode 8 is transmitted through the convex lens 3. The laser diode 8 emits higher energy and more directional light that can penetrate deeper water layers and interact more strongly with suspended particles in the water, thereby producing stronger scattered light. And the intensity and frequency of the light can be adjusted according to the different concentrations of suspended matter. When the reflected light is weak, it means that the concentration of suspended matter is high, and the light intensity can be further increased; when the reflected light is strong, it means that the concentration of suspended matter is low, and the current light intensity can be retained or adjusted appropriately. This enables the equipment to adapt to a wider range of detection environments and water types, improves the flexibility and application range of the equipment, and provides convenience for water quality detection and water pollution control.

[0055] Embodiment 3:

[0056] The difference from the above embodiment is that the detection chamber 2 includes several detection chambers, adjacent detection chambers are fixedly welded, and the bottom of the inner wall of the detection chamber is screwed to the pH sensor, conductivity sensor, dissolved oxygen sensor and heavy metal sensor, and the detection system is used to receive signals from the pH sensor, conductivity sensor, dissolved oxygen sensor and heavy metal sensor.

[0057] The bottom of the detection chamber is connected to a water outlet, and the output end of the water outlet is threadedly connected to a plug 9; the width of the detection chamber increases from left to right; a number of M-shaped straws 10 are embedded and installed at the connection between the detection chamber and the reflection cavity 1, and the height of the input end of the M-shaped straw 10 is lower than the height of the output end. The detection chamber and the reflection cavity 1 are interconnected through the M-shaped straw 10, and adjacent detection chambers are interconnected through the M-shaped straw 10.

[0058] The specific implementation process is as follows: first, when the water flows into the reflection cavity 1, due to the special design of the M-shaped straw 10 and the placement position of the input end of the M-shaped straw 10 is lower than the output end, the M-shaped straw 10 is placed at an angle, and the vertex close to the input end will be lower than the vertex close to the output end. Therefore, when the water level rises to the lower vertex of the M-shaped straw 10 for the first time, the water will be forced to turn and fall. This falling process is an accelerated motion process under gravity operation; at this time, the speed of the water flow will become faster and faster, forming a certain impact force; when the water flows to the turning point at the bottom of the M-shaped straw 10, it will continue to pass the highest point of the M-shaped straw 10 upwards due to the impact force, and then flow downward after passing the highest point of the M-shaped straw 10, and thus flow to the output end of the M-shaped straw 10; and due to the cohesive force of water, the water will continue to be transported to the output end of the M-shaped straw 10 until the water level is lower than the output end of the M-shaped straw 10, and then the flow stops.

[0059] In this way, water can be transported to the detection chamber. Compared with the traditional method of using a water pump for transmission, it does not require additional electric drive and relies entirely on gravity, so it has significant advantages in energy consumption. In addition, this method of smoothly transmitting water can reduce bubbles and turbulence in the water, further ensuring the accuracy and stability of each sensor reading. The pH sensor, conductivity sensor, dissolved oxygen sensor and heavy metal sensor can detect the pH value, conductivity, dissolved oxygen concentration and heavy metal ion content of the water, respectively, provide comprehensive water quality information, and evaluate the chemical properties, biological suitability, self-purification ability and potential pollution of the water.

[0060] At the same time, multiple parameters in the water sample are tested independently. The sensors in each test chamber focus on specific water quality parameters, reducing mutual interference between parameters and improving the accuracy and reliability of detection. In addition, the width of the test chamber increases from left to right, which can effectively control the liquid level difference between the test chambers, ensure that the flow speed and pressure of the water sample between different chambers remain consistent, and avoid detection errors caused by liquid level differences.

[0061] Embodiment 4:

[0062] The difference from the above embodiment lies in that the output end of the M-type straw 10 is connected to the solenoid valve 11, and the detection system is used to control the operation of the solenoid valve 11; the M-type straws 10 are distributed at equal intervals, and the installation height of the M-type straws 10 decreases from left to right; a number of partitions 15 are bolted and fixed in the detection chamber, and the partitions 15 are located above the output end of the M-type straw 10 adjacent to it; the partitions 15 are opened with leakage holes, and the leakage holes are connected to the one-way valve 16.

[0063] The specific implementation process is as follows: Because the M-shaped straws 10 are distributed at equal intervals in the detection chamber, and partitions 15 are installed above the output ends of the M-shaped straws 10, the corresponding capacities between adjacent partitions 15 are equal. In each detection chamber, the water volume corresponding to a scale value between adjacent partitions 15 can be obtained according to actual needs in combination with the corresponding sensor in the detection chamber. Through the precise control of the solenoid valve 11, a highly automated fluid delivery and metering system is formed. Each M-shaped straw 10 is connected to a specific detection chamber. When the sample detection and sampling of a layer of water is completed, the corresponding solenoid valve 11 is closed, and the sample of the next layer of water is detected and sampled, so as to realize the detection and sampling of water samples at different depths. After the water is taken, it can be taken out from the water outlet; if the sample taken is a multi-layer capacity liquid, the required sample can be obtained by opening the corresponding one-way valve 16.

[0064] For example, if the capacity of the scale value corresponding to the adjacent partitions 15 is 10mL, the water samples required are 10mL of liquid with pH values ​​of 6.5 and 7.0, respectively. At this time, the detection chambers are in communication with each other. When the pH sensor detects that the pH value is 6.5, the solenoid valve 11 of the first layer of the M-shaped straw 10 at the water input end of the corresponding pH detection chamber is opened, so that the capacity of the water flowing into the pH detection chamber is 10mL. After completing the detection and sampling of one layer of water, when the equipment continues to probe downward for detection, the pH sensor detects that the pH value is 7.0, and at this time, the solenoid valve 11 of the second layer of the M-shaped straw 10 is opened, so that the capacity of the water flowing into the second layer of the detection chamber is 10mL. By analogy, the capacity of water quality information of different concentration values ​​can be accurately detected and sampled.

[0065] Through this precise detection and sampling method, it is possible to ensure that the water volume used for each test is consistent, and water samples at different depths are collected, thereby reducing the capacity error that may be caused by traditional manual sampling. According to different detection requirements, the opening of the solenoid valve 11 can be flexibly adjusted to obtain the water volume of the corresponding concentration value to meet the needs of various detection projects. Accurate capacity control can effectively reduce the waste of water, which is crucial for assessing the degree of pollution, detecting water quality change trends, and formulating effective governance strategies. It not only improves the accuracy and efficiency of water quality detection, but also promotes the rational use of resources and the realization of environmental protection goals.

[0066] Embodiment 5:

[0067] The difference from the above embodiment is that the top wall of the detection chamber is snap-connected with a gas adsorption plate 12, and the material of the gas adsorption plate 12 is selected from one or more of activated carbon, silica gel, molecular sieve, porous ceramic and nano-mineral crystal.

[0068] The specific implementation process is as follows: The gas adsorption plate 12 can determine whether there is odor or pollution in the water body, based on the high affinity and adsorption capacity of the adsorption material for specific pollutants. When the water body contains volatile organic compounds VOCs, ammonia, hydrogen sulfide and other gases that may produce odor or indicate the presence of pollution, these gas molecules will be adsorbed on the gas adsorption plate 12. By detecting the changes in the adsorbed substances on the adsorption plate, the pollution status of the water body can be indirectly judged. The pollutant information on the gas adsorption plate 12 can help track the source of pollution, provide data support for pollution control and environmental remediation, help to timely discover potential sources of pollution in the water body, and provide a basis for early pollution warning and control.

[0069] Embodiment 6:

[0070] The difference from the above embodiment is that a telescopic rod 13 is fixedly connected with bolts on the outer side of the top of the detection chamber 2. The telescopic rod 13 includes a first rod and a second rod. The first rod is slidably fitted on the inner wall of the second rod. The side of the first rod away from the detection chamber 2 is rotatably fitted with a limiting bolt 14.

[0071] The specific implementation process is as follows: the telescopic rod 13 is composed of two sections, and the first rod and the second rod are slidably matched, allowing the first rod to be telescoped inside the second rod, thereby changing the overall length. The function of the limit bolt 14 is to fix the telescopic rod 13 by tightening the limit bolt 14 after it is adjusted to the required length, to prevent accidental expansion or contraction due to external force during use, and to ensure the stable positioning of the detection equipment in the water body. The adjustability of the telescopic rod 13 enables the detection equipment to flexibly adapt to water bodies of different depths, ensure the representativeness of the detection point, avoid detection deviations caused by water stratification or local pollution, and improve the accuracy and reliability of water quality parameter detection.

[0072] Embodiment 7:

[0073] The difference from the above embodiment is that the detection system includes a data collection module, a data transmission module, a data analysis module, a control module and an early warning module;

[0074] A data collection module is used to collect water quality information, including pH value, conductivity, dissolved oxygen concentration, heavy metal ion content and turbidity information;

[0075] A data transmission module, used to transmit the collected water quality information to the detection system via wireless transmission;

[0076] The data analysis module is used to analyze and mine water quality information after receiving it, extract key information, and provide processing solutions based on the key information;

[0077] A control module, used to control the operation of the laser diode 8 and the solenoid valve 11 in the device;

[0078] Early warning module, when the water quality information exceeds the preset threshold, the early warning module automatically sends an early warning signal to the detection system through wireless transmission.

[0079] The specific implementation process is as follows: The present invention realizes the automatic control of the detection system through the mutual cooperation between the modules, and timely detects the changes in water quality. Once the water quality information exceeds the safe range, the early warning module immediately issues an alarm. The early warning module of this embodiment includes a buzzer to ensure rapid response and reduce the expansion of environmental pollution. In addition, the detection system can predict equipment failure or water quality deterioration trend, which is convenient for arranging maintenance in advance, reducing operating costs and downtime. Through data analysis and processing, algorithms and models are used to analyze data, identify patterns, and formulate effective pollution control strategies based on accurate water quality data to maintain the ecological balance of water bodies and protect biodiversity.
