Description

Technical Field

[0001] This utility model relates to the field of coral temperature control experimental technology, specifically a coral temperature control experimental device. Background Technology

[0002] Indoor temperature stress simulation technology is an important tool for studying the response of marine organisms to temperature changes. Especially in the context of climate change and marine ecological protection, the reliability of its experimental results directly affects the depth of scientific research and its application value. However, current technology still has a series of key shortcomings, such as insufficient temperature control accuracy, inadequate dynamic temperature simulation capabilities, and insufficient real-time monitoring of temperature indicators.

[0003] Corals are cnidarians that are highly sensitive to temperature. Under the influence of global climate change, corals are prone to bleaching due to heat stress, with the optimal temperature generally considered to be 26°C. Long-term research has revealed that some corals can survive at temperatures ranging from 12.6°C to 32°C, but the precision of these temperature ranges is not high. Modern temperature control systems (such as PID controllers) can achieve an accuracy of ±0.1°C, which is particularly insufficient for corals, which are extremely sensitive to temperature. Further improvements in temperature control precision are needed to obtain more accurate experimental data on the effects of temperature.

[0004] Meanwhile, in natural environments, temperature changes often exhibit either periodicity (such as diurnal temperature variations) or abruptness (such as heat waves). However, existing equipment has limited temperature regulation rates; for example, raising the temperature from 15°C to 25°C may take several hours, making it difficult to simulate rapid temperature fluctuations over short periods. This difference between "gradual" and "abrupt" changes can lead to discrepancies between experimental data on biological stress responses and actual conditions. For instance, if the temperature rise rate in coral bleaching experiments is lower than that during natural heat waves, it may underestimate their heat tolerance threshold. Therefore, a multi-control approach is needed to more accurately simulate natural environmental temperatures.

[0005] During the experiment, the sampling frequency and spatial resolution of existing sensors (such as temperature recorders and dissolved oxygen probes) are limited, making it difficult to capture the instantaneous response of organisms to temperature changes. It is necessary to create a better human-computer interaction interface to achieve real-time and accurate control of temperature changes during the experiment. Utility Model Content

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Example

[0031] Please refer to Figures 1 to 3As shown, this embodiment provides a coral temperature control experimental device, including: a temperature control system, which includes a shell 1, gas filters installed on both sides of the shell 1, a temperature control module 4 fixedly installed on one side of the inner wall of the shell 1, a temperature control component 6 fixedly installed on the inner bottom of the shell 1, the temperature control component 6 being controlled by the temperature control module 4, a heat sink installed on the top of the shell 1, and a power module 5, a communication connector 8, and a power connector 9 fixedly installed on the inner wall of the shell 1; and an experimental tank system, which includes a glass tank 25 for placing corals, insulation components fixedly installed on the outer side and bottom of the glass tank 25, an insulation cover 27 snapped onto the top of the glass tank 25, and a temperature control circulation pump 32 fixedly installed on the inner bottom of the glass tank 25, the water inlet of the temperature control circulation pump 32 being connected to the interior of the glass tank 25. The outlet of the temperature-controlled circulating pump 32 is connected to the temperature control component 6 via a pipe; and the overall control system, the temperature control system and the experimental cylinder system are both controlled by the overall control system. The gas filters on both sides of the outer shell 1 can effectively block harmful gases and impurities from the outside, creating a stable operating environment for the internal temperature control module and temperature control component, extending the service life of the equipment. The temperature control module 4 precisely controls the temperature control component 6 to achieve precise temperature control, meeting the temperature-sensitive experimental needs of corals. The top heat sink promptly dissipates the heat generated by the system operation, ensuring system temperature stability and improving the stability of the device operation. The setting of the power module 5, communication connector 8 and power connector 9 respectively solves the problems of power supply, data communication and power access of the device, ensuring energy supply and information exchange between the systems.

[0032] The glass tank 25 provides a stable growth space for corals. The insulation components on its outer wall and bottom, as well as the insulation cover 27 on the top, effectively reduce heat loss, maintain a stable water temperature in the tank, and reduce energy consumption. The temperature control circulation pump 32 realizes water circulation between the experimental tank and the temperature control components, and can adjust the water temperature in the tank in a timely manner to create a suitable temperature environment for corals.

[0033] The unified control of the temperature control system and the experimental cylinder system by the central control system makes the operation of the entire device more intelligent and efficient, facilitates centralized management and control by operators, and improves the operability of the experiment and the accuracy of the experimental results.

[0034] The temperature control component 6 includes a water-cooled plate 11 and a heat sink 12 mounted on the water-cooled plate 11. A cooling fan 13 is fixedly connected to the top of the heat sink 12 by a second screw 19. A heat insulation pad 14 is fixedly installed between the water-cooled plate 11 and the heat sink 12. A thermoelectric cooler 20 is embedded in the middle of the heat insulation pad 14, and the hot end of the thermoelectric cooler 20 contacts the bottom of the heat sink 12. The water-cooled plate 11 includes a cold water plate base 24. The heat sink 12 is fixedly connected to the cold water plate base 24 by a first screw 18. A cold water plate heat-conducting plate 22 is fixedly connected to the cold water plate base 24 by a third screw 21. A cold water plate sealing ring 23 is fixedly installed at the bottom of the cold water plate heat-conducting plate 22. The cold end of the thermoelectric cooler 20 contacts the top of the cold water plate heat-conducting plate 22. Two cold water plate supply pipes 16 are fixedly connected to one side of the seat 24. One end of one cold water plate supply pipe 16 is connected to the outlet of the temperature control circulation pump 32 through a pipe, and the other end of the cold water plate supply pipe 16 is connected to the inside of the glass tank 25 through a pipe. The temperature control module 4 is electrically connected to the temperature control sensor 10, the cooling fan 13, and the semiconductor cooling chip 20 respectively. The detection end of the temperature control sensor 10 is placed inside the glass tank 25. Through the structural design of the temperature control component, the water-cooled plate 11 and the heat sink 12 are tightly fitted together, and the heat insulation pad 14 and the semiconductor cooling chip 20 are installed in the middle to form an efficient heat exchange and cooling / heating mechanism. The cooling fan 13 further enhances the heat dissipation effect, ensuring that the heat generated by the semiconductor cooling chip 20 during operation can be dissipated in time to maintain the stable operation of the system.

[0035] The design of components such as the cold water plate base 24, the cold water plate heat conduction plate 22, and the cold water plate sealing ring 23 ensures the good sealing and heat conduction performance of the water-cooled plate 11. The connection between the cold water plate water supply pipe 16 and the glass cylinder 25 and the temperature control circulation pump 32 constructs a complete water circulation path, enabling the temperature control component to accurately adjust the water temperature in the experimental cylinder and improve the temperature control accuracy.

[0036] By electrically connecting the temperature control module 4 to the temperature control sensor 10, the cooling fan 13, and the thermoelectric cooler 20, real-time monitoring and precise control of temperature are achieved. The temperature control sensor 10 feeds back the actual water temperature in the glass tank 25 to the temperature control module 4. The temperature control module 4 adjusts the working state of the thermoelectric cooler 20 and the cooling fan 13 in a timely manner according to the feedback signal to ensure that the water temperature is stable within the range required for the experiment.

[0037] The bottom of the outer casing 1 is fitted with a condensate collection tray 3. The base of the heat sink 12 is provided with a condensate collection groove. The opening of the condensate collection groove is fixedly connected to a conduit 15. The lower end of the conduit 15 extends into the condensate collection tray 3. By fitting the condensate collection tray 3 at the bottom of the outer casing 1, in conjunction with the condensate collection groove and the conduit 15 on the heat sink 12, the condensate generated during the operation of the semiconductor cooling chip 20 can be collected in a timely manner. This prevents the condensate from accumulating inside the device and prevents it from causing short circuits, corrosion and other damage to electrical components. This greatly improves the safety and stability of the device operation and extends the service life of the equipment. In addition, when the condensate collection tray 3 collects too much condensate, the condensate collection tray 3 can be pulled out from the front of the outer casing 1 to pour out the collected condensate.

[0038] The cold water plate water supply pipe 16 is made of POM material. The low thermal conductivity of POM material can reduce the influence of external temperature on the water inside the water-cooled plate 11. The cold water plate heat conduction plate 22 is made of 316L material that is resistant to seawater corrosion. The heat sink 12 is made of copper material with good thermal conductivity. During installation, both the hot and cold sides of the semiconductor cooling chip 20 are coated with thermal grease to improve the heat conduction efficiency.

[0039] Among them, a spring 17 is fitted on the first screw 18. The spring 17 is compressed on the substrate of the heat sink 12. By fitting the spring 17 on the first screw, the elasticity of the spring 17 plays a buffering role when fastening the heat sink 12 and other components, avoiding excessive compression of the thermoelectric cooler 20 due to excessive screw tightening force. This effectively protects the thermoelectric cooler 20, a key component, and ensures its normal operation, thereby guaranteeing the stable operation and temperature control effect of the entire temperature control component.

[0040] The filter element includes two filter screens 2, which are made of glass fiber filter cotton. The two filter screens 2 are respectively fitted and snapped onto both sides of the outer shell 1. By using the glass fiber filter cotton filter screens 2 as the gas filter element, it has good filtration performance and can effectively filter salt spray particles, dust and other impurities in the air, preventing these impurities from entering the temperature control system and avoiding corrosion and damage to precision components such as the temperature control module 4 and temperature control component 6, thereby improving the reliability and service life of the device.

[0041] The heat dissipation component is an exhaust fan 7. The top of the outer casing 1 has a ventilation opening, and the exhaust fan 7 is fixedly installed inside the ventilation opening. By setting the exhaust fan 7 as a heat dissipation component and installing it inside the ventilation opening at the top of the outer casing 1, the heat generated by the operation of the temperature control system can be quickly dissipated, the air circulation can be accelerated, the internal temperature of the system can be reduced, and the temperature control system can be maintained within a suitable temperature range. This helps to ensure the stability and temperature control accuracy of the system and provide a stable and reliable temperature control environment for coral experiments.

[0042] The insulation component is insulation board 26, which is made of rock wool. The insulation cover 27 is made of translucent double-layer acrylic board. The rock wool insulation board 26 has excellent thermal insulation performance, which can effectively reduce the heat loss from the glass tank 25, maintain the water temperature in the tank, and reduce energy consumption. The translucent double-layer acrylic insulation cover 27 not only ensures good insulation effect, but also does not affect the light entering, meeting the light requirements for coral growth, creating suitable environmental conditions for coral experiments, and promoting the healthy growth of corals and the smooth progress of experiments.

[0043] The glass tank 25 is equipped with a circulating filtration assembly, which includes a filter box 28 and a filter circulation pump 29. The filter circulation pump 29 is fixedly installed inside the glass tank 25, with its inlet connected to the interior of the glass tank 25 and its outlet connected to the inlet of the filter box 28 via a pipe. The filter box 28 includes a box body with an inlet at the top and an outlet at the bottom. A ceramic filter plate is fixedly installed on the inner wall of the middle section of the box body. Multiple sets of positioning glass plates 33 at different heights are vertically fixedly installed on one side of the inner wall of the glass tank 25. A support glass plate 34 is snapped in place, and a filter box 28 is installed on top of the support glass plate 34. By installing a circulating filter assembly inside the glass tank 25, the water in the tank is transported to the filter box 28 by a circulating pump 29. The ceramic filter plate in the middle of the filter box 28 can effectively filter impurities in the water, purify the water quality, and provide a clean living environment for corals. In addition, by positioning the glass plate 33 and the support glass plate 34 at different heights, the installation height of the filter box 28 can be flexibly adjusted to meet different experimental needs, such as the different requirements of corals at different growth stages for water flow and water quality, thus improving the applicability of the device and the adjustability of the experiment.

[0044] The glass tank 25 has a protein separator 30 fixedly installed on its inner wall by a suction cup. By installing the protein separator 30 on the inner wall of the glass tank 25, the protein separator 30 can effectively remove organic matter such as protein from the water, prevent it from decomposing and producing harmful substances, further purify the water quality, promote the healthy growth of corals, reduce the occurrence of diseases, improve the survival quality of corals in the experimental environment, and improve the accuracy and reliability of the experimental results.

[0045] A wave-making pump 31 is fixedly installed on the inner wall of the glass tank 25. By installing the wave-making pump 31 on the inner wall of the glass tank 25, the natural water flow environment can be simulated, creating a living condition for corals that is closer to nature. The circulation of water helps to distribute oxygen evenly, promote water mixing, and remove impurities, meeting the physiological needs of corals for water flow, improving the adaptability of corals in the experimental environment, making the experimental results more reflective of the true state of corals in the natural environment, and enhancing the scientificity and effectiveness of the experiment.

[0046] The main control system is a PLC controller, using a PLC touch screen all-in-one machine with an RS485 external communication port as the host computer. Its model is Siemens S7-1200. The main control system uses the Modbus RTU protocol to control the temperature control system and the experimental cylinder system in real time. The temperature control module 4 can be RC-2104H, the power supply module 5 can be LRS-600-12, the temperature sensor 10 can be MF52B, the semiconductor refrigeration chip 20 can be TEC3-22908, the protein separator 30 can be AC-2000, and the wavemaker pump 31 can be the Laoyujiang fourth generation 55W wavemaker pump.

[0047] As is well known to those skilled in the art, the working principles and wiring methods of the main control system, temperature control module 4, power supply module 5, exhaust fan 7, communication connector 8, power connector 9, temperature control sensor 10, cooling fan 13, semiconductor cooling chip 20, filter circulation pump 29, protein separator 30, wave generator pump 31, and temperature control circulation pump 32 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can arbitrarily select and match their models according to their needs or convenience.

[0048] Working principle:

[0049] By connecting the power connector 9, the power module 5 starts to work, providing stable power to the entire device and ensuring that the temperature control module 4, temperature control circulation pump 32, wave generator pump 31, circulation pump 29, protein separator 30 and other equipment are powered on.

[0050] Through communication connector 8, the central control system establishes a communication connection with the temperature control system and the experimental cylinder system to obtain the initial status information of each device and set the overall parameters of the device, such as the target water temperature required for the experiment, the water flow mode and intensity of the wave generator pump, and the working time of the filter components.

[0051] The air entering the outer casing 1 is continuously filtered by the filter screen 2 to prevent impurities from entering and to create a clean operating environment for the internal equipment.

[0052] The temperature sensor 10 monitors the water temperature in the glass tank 25 in real time and transmits the data to the temperature control module 4. The temperature control module 4 compares the current water temperature with the preset target temperature. If the water temperature is higher than the target value, the temperature control module 4 activates the semiconductor cooling chip 20. Its cold end absorbs the heat from the water sent by the temperature control circulation pump 32 through the cold water plate heat conduction plate 22, and the hot end transfers the heat to the heat sink 12. The cooling fan 13 turns on to accelerate the heat dissipation of the heat sink 12. At the same time, the temperature control circulation pump 32 draws out the hot water in the glass tank 25 and sends it through the pipe to the cold water plate water supply pipe 16 of the cold water plate base 24. After absorbing the cold energy and cooling down, it flows back to the glass tank 25 through another cold water plate water supply pipe 16 to achieve a decrease in water temperature. If the water temperature is lower than the target value, the temperature control module 4 can control and adjust the working state of the semiconductor cooling chip 20 to reduce the cooling capacity. At the same time, it works with the temperature control circulation pump 32 to circulate the water and make the water temperature rise.

[0053] The exhaust fan 7 continuously operates to expel the heat generated by the equipment operation inside the outer casing 1, maintain the stable internal temperature of the temperature control system, and ensure the normal operation of each piece of equipment. The condensate generated during this period is collected through the condensate collection groove at the base of the heat sink 12 and flows into the condensate collection tray 3 through the conduit 15.

[0054] The heat loss inside the glass tank 25 is reduced by the heat insulation plate 26 and the heat insulation cover plate 27, thus maintaining a stable water temperature and reducing energy consumption.

[0055] The water is continuously circulated by the temperature-controlled circulation pump 32 to ensure a uniform water temperature in the glass tank 25, and the water temperature is adjusted in conjunction with the temperature control component 6.

[0056] Water in glass tank 25 is pumped into filter box 28 by circulating pump 29. After being filtered by ceramic filter plate to remove impurities, the water flows back to glass tank 25 from the outlet, thus purifying the water. The installation height of filter box 28 can be flexibly adjusted by positioning glass plate 33 and supporting glass plate 34 to meet different experimental needs.

[0057] The protein separator 30 works continuously, using the principle of air flotation to remove organic matter such as proteins from the water, further purifying the water quality.

[0058] The wave pump 31 generates a high-intensity water flow to simulate a strong natural water flow, providing a suitable environment for corals that require strong water flow stimulation, while also helping to remove impurities.

[0059] In summary, the central control system monitors the operating status and parameters of each device in the temperature control system and experimental tank system in real time, such as temperature, water flow intensity, and equipment operating time. According to changes in experimental requirements, control commands are sent to the temperature control system and experimental tank system through communication connector 8 to adjust the operating status of the equipment, ensure that the experiment proceeds as planned, and record various data during the experiment, such as temperature change curves and changes in water quality parameters, to facilitate subsequent analysis of experimental results.
