Water quality monitoring device for aquaculture

Abstract

This utility model relates to the field of aquaculture equipment technology, specifically disclosing a water quality monitoring device for aquaculture, including a sampler; it also includes a collection mechanism, which is set on one side of the sampler. The collection mechanism collects water samples and performs self-cleaning of the inlet. In this utility model, the gill plates are made of fine stainless steel wire mesh, and the naturally formed 0.5-1mm gaps can play a preliminary filtering role for larger particles of impurities. When impurities touch the gill plates, the gill plates are subjected to force and undergo slight deformation, which temporarily narrows the gaps and further blocks the entry of large particles of impurities. At the same time, during the impurity removal stage triggered every 1-2 samplings, the first electromagnet and the second electromagnet are alternately energized, causing the gill plates to contract rapidly inward and generate high-frequency vibration, which can shake off algae, fine silt and other impurities attached to the surface of the gill plates back into the water, thus achieving self-cleaning of the inlet.

Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to a water quality monitoring device for aquaculture. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It is a crucial industry in my country's agriculture, providing people with abundant aquatic food products. In recent years, during the research and promotion of aquaculture methods suitable for the current aquaculture industry, utilizing technological means to collect real-time data on aquaculture water quality and adjusting the water quality based on this data has become one of the most important methods for improving aquaculture technology and enhancing the overall production capacity of the aquaculture industry.

[0003] Existing aquaculture water quality monitoring devices are prone to clogging of sampling pipes due to the presence of large amounts of impurities such as silt, algae, and plankton in the water, leading to sampling failure or data deviation. Plastic components are also prone to aging at high temperatures, and the performance of electronic components may be affected, resulting in decreased sampling accuracy or equipment failure. Furthermore, water samples are easily affected by fluctuations, causing inaccurate data collection. Therefore, we propose a new aquaculture water quality monitoring device. Utility Model Content

[0004] The purpose of this utility model is to provide a water quality monitoring device for aquaculture, in order to solve the problems mentioned in the background art, such as the presence of a large amount of impurities such as silt, algae, and plankton in the water, which easily clog the sampling pipeline, leading to sampling failure or data deviation; the easy aging of plastic parts at high temperatures, resulting in decreased sampling accuracy or equipment failure; and the water sample being easily affected by fluctuations, causing inaccurate collection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality monitoring device for aquaculture, comprising: a sampler;

[0006] It also includes: a collection mechanism, which is located on one side of the sampler, collects water samples, and performs self-cleaning at the inlet;

[0007] The cooling mechanism is located inside the sampler and cools the sampler.

[0008] The collection mechanism includes a peristaltic pump fixedly connected to one side of the sampler. One end of the peristaltic pump is fixedly connected to a first connecting tube, and one end of the first connecting tube is fixedly connected to a placement box. The placement box has an opening and closing mechanism inside. One side of the placement box is fixedly connected to a first fixing tube, and one end of the first fixing tube is fixedly connected to a sampling head.

[0009] The opening and closing mechanism includes a first support ring fixedly connected to the placement box, a first electromagnet fixedly connected inside the first support ring, a first connecting plate magnetically connected to one end of the first electromagnet, a second support ring fixedly connected to the side of the placement box away from the first support ring, a second electromagnet fixedly connected inside the second support ring, a second connecting plate magnetically connected to one end of the second electromagnet, gill plates fixedly connected to one end of both the first and second connecting plates, and a flow guide groove provided inside the placement box, which is adapted to the gill plates.

[0010] Each of the first and second connecting plates has a spring rod fixedly connected to one side, and a support plate is fixedly connected to one end of the spring rod. The support plate is fixedly connected inside the placement box.

[0011] The cooling mechanism includes a first water outlet pipe connected to the sampler by a fixed pipe, a heat exchanger fixedly connected to one end of the first water outlet pipe, a first water inlet pipe fixedly connected to one end of the heat exchanger, a second water inlet pipe fixedly connected to the end of the heat exchanger away from the first water outlet pipe, a second water outlet pipe fixedly connected to the end of the heat exchanger away from the first water inlet pipe, and a second fixed pipe fixedly connected to one side of both the second water inlet pipe and the second water outlet pipe.

[0012] The sampler has a first slot inside that is compatible with the first water inlet pipe, and a second slot inside that is compatible with the first water outlet pipe.

[0013] One end of the peristaltic pump is fixedly connected to a second connecting pipe, which is fixedly connected to one side of the sampler.

[0014] This utility model has at least the following beneficial effects:

[0015] This invention utilizes a collection mechanism where the gill plates are made of fine stainless steel wire mesh. The naturally formed 0.5-1mm gaps can provide initial filtration for larger particles of impurities. When impurities touch the gill plates, the gill plates undergo slight deformation under force, temporarily narrowing the gaps and further preventing large particles of impurities from entering. Simultaneously, during the impurity removal stage triggered every 1-2 samplings, the first and second electromagnets are alternately energized, causing the gill plates to rapidly contract inward and generate high-frequency vibrations. This shakes off algae, fine silt, and other impurities attached to the surface of the gill plates and returns them to the water, achieving self-cleaning of the inlet.

[0016] This invention utilizes a cooling mechanism where a heat exchanger forms a medium circulation with the sampler's internal cooling area via a first inlet and a first outlet pipe. Simultaneously, it circulates with an external cooling source via a second inlet and a second outlet pipe, achieving efficient heat exchange to cool the sampler's interior. This process ensures that the sampler and sample are within a suitable temperature range, effectively preventing the impact of high temperatures on water sample properties, reducing aging of plastic components and performance fluctuations of electronic components, and guaranteeing stable operation of the monitoring equipment and reliable monitoring results.

[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] Please see Figures 1 to 6 This utility model provides a technical solution: a water quality monitoring device for aquaculture, comprising: a sampler 1;

[0027] It also includes: a collection mechanism 2, which is located on one side of the sampler 1. The collection mechanism 2 collects water samples and performs self-cleaning of the inlet.

[0028] Cooling mechanism 3 is located inside sampler 1 and cools sampler 1.

[0029] The collection mechanism 2 includes a peristaltic pump 21 fixedly connected to one side of the sampler 1. One end of the peristaltic pump 21 is fixedly connected to a first connecting tube 22. One end of the first connecting tube 22 is fixedly connected to a placement box 23. The placement box 23 is provided with an opening and closing part 24. One side of the placement box 23 is fixedly connected to a first fixing tube 25. One end of the first fixing tube 25 is fixedly connected to a sampling head 26.

[0030] The opening and closing component 24 includes a first support ring 241 fixedly connected to the placement box 23. A first electromagnet 242 is fixedly connected inside the first support ring 241. One end of the first electromagnet 242 is magnetically connected to a first connecting plate 243. A second support ring 244 is fixedly connected to the side of the placement box 23 away from the first support ring 241. A second electromagnet 245 is fixedly connected inside the second support ring 244. One end of the second electromagnet 245 is magnetically connected to a second connecting plate 246. One end of both the first connecting plate 243 and the second connecting plate 246 is fixedly connected to a gill plate 247. A flow guide groove 27 is provided inside the placement box 23, and the flow guide groove 27 is adapted to the gill plate 247.

[0031] A spring rod 28 is fixedly connected to one side of both the first connecting plate 243 and the second connecting plate 246. A support plate 29 is fixedly connected to one end of the spring rod 28. The support plate 29 is fixedly connected inside the placement box 23.

[0032] The placement box 23 serves as a temporary storage and control component for water samples during collection. It contains an opening / closing mechanism 24. Made of high-strength, transparent plastic, the placement box 23 facilitates observation of the internal water sample and the operational status of the opening / closing mechanism 24. When the water sample flow path needs to be opened, energizing the first electromagnet 242 and the second electromagnet 245 generates a magnetic field that attracts the first connecting plate 243 and the second connecting plate 246, causing the gill plates 247 to open. When the first electromagnet 242 and the second electromagnet 245 are not energized, the first connecting plate 243 and the second connecting plate 246 remain in their initial positions under the action of the spring rod 28. The spring rod 28 is made of stainless steel, possessing excellent elasticity and corrosion resistance. Its elastic coefficient has been precisely calculated and tested to ensure that, under normal operating conditions, the first connecting plate 243 and the second connecting plate 246 can quickly reset when the first electromagnet 242 and the second electromagnet 245 are de-energized. Simultaneously, the first electromagnet 242 and the second electromagnet 246... 5. When energized, it can be smoothly attracted and moved. The gill plates 247 are made of fine stainless steel wire mesh, which can ensure the normal flow of water samples and also filter larger particles in the water sample. A gap of 0.5-1mm is naturally formed between the gill plates 247 (which can be finely adjusted according to the size of impurities in the water). When impurities touch the gill plates, the gill plates undergo slight deformation due to the force, and the gap temporarily narrows, blocking large particles from entering. During water intake, the first electromagnet 242 and the second electromagnet 24... 5. When energized, the gill plate 247 opens to overcome the restoring force of the spring rod 28, and the water sample enters the first connecting tube 22 through the gap. During the impurity removal stage (triggered once every 1-2 samplings), the first electromagnet 242 and the second electromagnet 245 are alternately energized, and the gill plate 247 quickly contracts inward (similar to the gill cover closing), and the gap is completely closed. At the same time, a high-frequency vibration of 0.1 seconds (amplitude 0.5mm) is generated, which shakes the impurities (such as algae and fine silt) attached to the surface of the gill plate back into the water.

[0033] The cooling mechanism 3 includes a first water outlet pipe 31 fixedly connected to the sampler 1. A heat exchanger 32 is fixedly connected to one end of the first water outlet pipe 31. A first water inlet pipe 33 is fixedly connected to one end of the heat exchanger 32. A second water inlet pipe 34 is fixedly connected to the end of the heat exchanger 32 away from the first water outlet pipe 31. A second water outlet pipe 35 is fixedly connected to the end of the heat exchanger 32 away from the first water inlet pipe 33. A second fixed pipe 4 is fixedly connected to one side of both the second water inlet pipe 34 and the second water outlet pipe 35.

[0034] The sampler 1 has a first slot inside that is compatible with the first water inlet pipe 33, and a second slot inside that is compatible with the first water outlet pipe 31.

[0035] The first inlet pipe 33 and the first outlet pipe 31 are used for the circulation of the medium between the cooling area inside the sampler 1 and the heat exchanger 32. The second inlet pipe 34 and the second outlet pipe 35 are used for the circulation of the medium between the external cooling source and the heat exchanger 32. The heat exchanger 32 is the core component of the cooling mechanism 3. Through the heat exchange of hot and cold media, it achieves the cooling of the sampler 1, ensuring that the temperature of the sampler 1 and the sample is within a suitable range, and avoiding excessive temperature from affecting the properties of the water sample or the normal operation of the device components. The second fixed pipe 4 circulates the medium inside the heat exchanger 32 to ensure its stability during operation and prevent heat exchange effect. It provides installation space for the first inlet pipe 33 and the first outlet pipe 31, so that the pipes can be reasonably arranged inside the sampler 1 without affecting the operation of other components, and at the same time protects the pipes from external interference.

[0036] Example 2

[0037] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that one end of the peristaltic pump 21 is fixedly connected to a second connecting pipe 5, which is fixedly connected to one side of the sampler 1.

[0038] The second connecting pipe 5 connects the peristaltic pump 21 and the sampler 1. The peristaltic pump 21 transports the water sample from the outside through the second connecting pipe 5 into the sampler 1 for sampling.
