Description

Technical Field

[0001] The utility model relates to the technical field of liquid detection, in particular to an aquaculture monitoring system. Background Art

[0002] An aquaculture monitoring system integrates multiple sensors, data acquisition devices, and information processing technologies to monitor and manage the health of the aquaculture environment and organisms in real time. The system aims to improve the efficiency, sustainability, and economic benefits of aquaculture, ensure optimal growth conditions for aquatic organisms, and reduce risks.

[0003] When it comes to water quality testing for aquaculture, the detection of ammonia nitrogen and nitrite is particularly important. Ammonia nitrogen is a common harmful substance in water, primarily derived from fish excrement, unconsumed feed, and the decomposition of organic matter. Ammonia nitrogen is toxic to aquatic organisms, especially at high concentrations, causing poisoning in fish and other aquatic organisms, impacting their growth and survival. Nitrite is an intermediate product in the nitrogen cycle, typically converted from ammonia nitrogen by nitrifying bacteria. Nitrite is also toxic to aquatic organisms, particularly the blood system of fish, potentially causing hypoxia and death. Excessive concentrations of ammonia nitrogen and nitrite can disrupt the ecological balance of the water body, leading to deterioration of water quality and affecting the living environment of aquatic organisms. Monitoring these indicators through an aquaculture monitoring system allows timely measures to maintain the ecological stability of the water body.

[0004] However, existing water sample analyzers, such as the universal high-precision automatic analyzer disclosed in Patent Publication No. CN105974148B, extract water samples through a peristaltic pump, and the sample liquid enters a fluid meter for sampling, and then the liquid is passed through a sample detection device to measure the component values in the liquid.

[0005] However, most existing aquaculture monitoring systems conduct a comprehensive test on water samples. The single test data has accidental errors, and the reliability and accuracy of the test data are low. In order to solve the above-mentioned problems, an aquaculture monitoring system is now provided. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 This embodiment provides an aquaculture monitoring system, including a mounting plate 1 of the device, which is fixedly installed inside the water sample analyzer and is used to fix and install the components of the analyzer. A peristaltic pump 2, a photoelectric meter 3, a multi-way valve 4, and a photoelectric detector 5 are fixedly installed on the end surface of the mounting plate 1. The peristaltic pump 2 pipeline is connected to the upper ends of the photoelectric meter 3 and the photoelectric detector 5, and the multi-way valve 4 pipeline is connected to the lower ends of the photoelectric meter 3 and the photoelectric detector 5. Figure 1 and Figure 2As shown, the peristaltic pump 2, the photoelectric meter 3, the multi-way valve 4 and the photoelectric detector 5 form an annular passage.

[0028] During use, the peristaltic pump 2 draws the water sample and transports it to the photoelectric meter 3. The photoelectric meter 3 quantitatively transports the water sample to the inside of the multi-way valve 4. The multi-way valve 4 then transports the water sample to the photoelectric detector 5 for detection. The detection principle of the photoelectric detector 5 refers to the multi-parameter water quality analyzer model JH-TD400, which detects the water quality by spectrophotometry. Spectrophotometry is a commonly used water quality detection method, which is widely used to determine the concentration of various solutes in water, including heavy metal ions, nutrients such as nitrogen, phosphorus, organic matter, etc. Its basic principle is to use the absorption characteristics of light to quantitatively analyze specific components in the water sample. Therefore, by injecting the water sample into the photoelectric detector 5, ammonia nitrogen and nitrite in the water sample can be detected.

[0029] Photoelectric detector 5 first tests the water sample for ammonia nitrogen, then transfers the sample through a pipeline to peristaltic pump 2. Peristaltic pump 2 then sequentially passes the sample through photoelectric meter 3 and multi-way valve 4 before finally transferring it to photoelectric detector 5 for a secondary test to determine the nitrite content. This cycle, where the sample passes through peristaltic pump 2, photoelectric meter 3, multi-way valve 4, photoelectric detector 5, and then is transferred back to peristaltic pump 2, constitutes one cycle. Multiple cycles can be used for multiple tests, and calculating the average value of these multiple tests can reduce accidental errors and improve the reliability of the results.

[0030] The top end of the multi-way valve 4 is connected to the photoelectric meter 3 by piping. Twelve drainage ports are defined on the side of the multi-way valve 4. Three of these ports are connected to the photoelectric detector 5, the water sample, and the cleaning solution, respectively. The remaining nine ports are connected to various detection reagents. The detection reagents are similar to those connected to the multi-way injection valve in the universal high-precision automatic analyzer disclosed in Patent Publication No. CN105974148B. The drainage ports through which the water sample passes can be controlled by controlling the multi-way valve 4.

[0031] The lower end of the multi-way valve 4 is connected to a waste liquid bucket. By controlling the multi-way valve 4 to open the lower end opening, the tested water sample can be discharged into the waste liquid bucket for collection. The pipeline between the peristaltic pump 2 and the photoelectric detector 5 is connected to an overflow bottle 51, which is used to collect the water sample overflowing when the photoelectric detector 5 is testing the water sample.

[0032] like Figure 2 As shown, three solenoid valves 6 are installed on the end surface of the mounting plate 1. The three solenoid valves 6 are respectively installed on the pipeline between the multi-way valve 4 and the waste liquid bucket, the pipeline between the multi-way valve 4 and the photoelectric detector 5, and the pipeline between the photoelectric detector 5 and the overflow bottle 51. The opening and closing of the pipeline is controlled by the solenoid valve 6, thereby controlling the flow of the water sample.

[0033] like Figure 1As shown, a cam 7 for promoting liquid flow is installed on the pipeline between the peristaltic pump 2 and the photoelectric detector 5, wherein two cams 7 are provided, and the two cams 7 can be located on both sides of the connecting pipeline between the photoelectric detector 5 and the upper solenoid valve 6, on both sides of the connecting pipeline between the upper solenoid valve 6 and the overflow bottle 51, and on both sides of the connecting pipeline between the overflow bottle 51 and the peristaltic pump 2.

[0034] Two cams 7 are rotatably mounted on the end faces of the mounting plate 1, with the outer sidewalls of the cams 7 closest to the center of rotation abutting against the sides of the pipeline. Gears 71 are fixedly sleeved on the outer sidewalls of the cams 7, and the two gears 71 mesh with each other. A motor is mounted on the mounting plate 1, and the motor's output shaft is fixedly connected to one cam 7. By starting the motor, one cam 7 rotates, and the other cam 7 rotates synchronously via the two meshing gears 71.

[0035] The rotation direction of the two cams 7 is as follows Figure 5 As shown by the middle arrow, after cam 7 rotates, the outer wall of cam 7 farthest from the center of rotation will squeeze the pipeline, thereby driving the water flow in the pipeline toward peristaltic pump 2. To maintain the stability of the pipeline, the pipeline can be fixed by two fixing rings. The two fixing rings are symmetrically arranged around the two cams 7 as the axis of symmetry. They fix the pipeline squeezed by cam 7 and prevent the cam 7 from causing the pipeline to move and deviate.

[0036] When the cam 7 squeezes the pipeline, in order to prevent the pipeline from escaping from between the two cams 7, the end of the cam 7 away from the mounting plate 1 is fixedly connected to a limit head 72, and the gap between the two limit heads 72 is smaller than the diameter of the pipeline, thereby preventing the pipeline from escaping from between the cams 7 through the gap between the two limit heads 72.

[0037] When the cams 7 rotate, the pipeline moves between the cams 7. When the pipeline moves and contacts the gears 71, the rotating gears 71 will wear the pipeline. To prevent the pipeline from being worn, the outer walls of the two cams 7 are sleeved with a cover 73. The cover 73 is threaded onto the mounting plate 1 and covers the two gears 71, isolating the gears 71 from the pipeline and preventing wear from the rotating gears 71.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
