Description

Technical Field

[0001] This application relates to the field of thermal convection simulation technology, and in particular to a horizontal thermal convection test device. Background Technology

[0002] In the ocean system, seawater movement follows specific physical laws and forms complex circulation patterns. In the high-latitude waters near Iceland, surface seawater increases in density due to intense cooling, and salt precipitation occurs during condensation, further increasing the salinity of the surrounding waters. This cold, high-salinity seawater, due to its high density, forms a sinking current, which becomes a significant driving force for the flow of warm surface currents (such as the Gulf Stream and the North Atlantic Current). Simultaneously, bottom seawater gradually rises back to the surface in specific regions (mainly in the Indian Ocean and the North Pacific), forming cold subsurface currents. These vertical seawater movements, combined with the resulting horizontal circulation, constitute the largest-scale dynamic processes in the ocean, playing a crucial role in the distribution of marine ecological resources, global heat balance, and climate regulation, such as regulating CO2 concentration distribution. In-depth research into these ocean circulation phenomena is crucial for understanding the mechanisms of matter and energy transport in the ocean, elucidating the impact of horizontal convection on ocean heat distribution, revealing the ocean's role in climate change, mastering the transport patterns of nutrients to maintain marine ecological health, and exploring their connection with extreme weather events (such as hurricanes) to improve climate event prediction capabilities. However, current technologies lack models capable of effectively simulating and studying these complex ocean circulation processes, particularly their driving mechanisms and matter and energy transport, making it difficult to meet the needs of in-depth research and accurate prediction. Therefore, a new solution is urgently needed to address these shortcomings. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a horizontal thermal convection experimental device as a model device that can effectively simulate and study complex ocean circulation processes, especially their driving mechanisms, material and energy transport and climate and ecological effects.

[0004] To achieve the above-mentioned technical objectives, this application provides a horizontal thermal convection testing device, including a device body, at least one first temperature control device, at least one second temperature control device, a detection device, and a heat insulation partition.

[0017] The guide rod is vertically connected to the connecting block;

[0018] The first vertical displacement mechanism is fixedly connected to a guide block through which the guide rod moves.

[0019] Furthermore, both the first temperature control device and the second temperature control device also include a first horizontal displacement mechanism;

[0020] The first horizontal displacement mechanism is connected to the first vertical displacement mechanism and is used to drive the first vertical displacement mechanism to move along the length direction of the test chamber.

[0021] Furthermore, the temperature control unit has a first splicing structure on one side and a second splicing structure on the other side that splices and cooperates with the first splicing structure;

[0022] Alternatively, the heat-conducting unit may have a third splicing structure on one side and a fourth splicing structure on the other side that is spliced ​​and cooperates with the third splicing structure.

[0023] Furthermore, the first splicing structure and / or the second splicing structure are extendable and adjustable so that the splicing distance between adjacent temperature control units is adjustable;

[0024] Alternatively, the third splicing structure and / or the fourth splicing structure may be adjustable to make the splicing distance between adjacent heat-conducting units adjustable.

[0025] Furthermore, a plurality of second horizontal displacement mechanisms are installed on the main body of the device;

[0026] The detection device includes several temperature sensors that extend into the test chamber;

[0027] Each of the second horizontal displacement mechanisms is connected to the temperature sensor in a one-to-one manner, and can drive the connected temperature sensor to move along the length of the test chamber.

[0028] Furthermore, a second vertical displacement mechanism is installed on the second horizontal displacement mechanism;

[0046] 1. By designing a first temperature control device and a second temperature control device with a first vertical displacement mechanism, cold and heat sources can be arranged at the same horizontal height, thereby accurately simulating the horizontal convection process in ocean circulation. This provides an effective model for studying the driving mechanism of ocean circulation (such as the power source of surface warm current driven by high-latitude sinking water flow), and helps to understand the transport mechanism of matter and energy in the ocean and the impact of horizontal convection on ocean heat distribution.

[0047] 2. Both the first and second temperature control devices adopt detachable and independently controllable temperature control units, which can realize multi-size constant temperature fields or gradual temperature fields. They can simulate the temperature distribution characteristics of different latitudes and regions in the ocean (such as the temperature gradient between high-latitude low-temperature areas and low-latitude high-temperature areas), meet diverse experimental needs, and help to study in depth the impact of temperature fields on the distribution of marine ecological resources, global heat balance and climate regulation (such as CO2 concentration regulation).

[0048] 3. By designing heat-insulating partitions, the test chamber can be divided into at least two (same or different lengths) independent chambers, enabling two tests to be conducted simultaneously and each chamber to independently arrange heat and cold sources, significantly improving test efficiency. It can simultaneously compare the horizontal convection effects under different conditions (such as different heat and cold source intensities, different temperature field distributions, and different lengths), accelerate the revelation of the ocean's role in climate change, nutrient transport patterns, and its connection with extreme weather events (such as hurricanes), and improve the ability to predict climate events.

[0049] In summary, this technology solves the problem that existing technologies cannot effectively simulate complex ocean circulation processes (driving mechanisms, material and energy transport, etc.), providing a more comprehensive and efficient experimental device for marine science research and meeting the needs for in-depth exploration and accurate prediction of ocean circulation phenomena.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

[0065] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0067] This application discloses a horizontal thermal convection test apparatus.

[0068] Please see Figures 2 to 4 One embodiment of the horizontal thermal convection test apparatus provided in this application includes:

[0069] The device body, at least one first temperature control device 201, at least one second temperature control device 202, a detection device 400, and a heat insulation partition 300.

[0070] The device body is provided with a rectangular test chamber 101; the first temperature control device 201 and the second temperature control device 202 both include a first vertical displacement mechanism 21 and a temperature control module; the temperature control module includes several temperature control units 22 that can be separated and assembled along the length direction of the test chamber 101 and independently controlled; the first vertical displacement mechanism 21 is installed on the device body and connected to the temperature control module, and is used to drive the temperature control module to move and extend into the test chamber 101 along the height direction of the test chamber 101.

[0071] The first vertical displacement mechanism 21 can be a lifting actuator such as a lifting cylinder, which realizes the precise lifting and lowering of the temperature control module in the height direction of the test chamber 101 through telescopic movement, thereby flexibly adjusting the contact position or distance between the temperature control module and the medium in the test chamber 101.

[0072] The detection device 400 is installed on the main body of the device and is used to detect the temperature of the test chamber 101. The heat insulation partition 300 is detachably installed on the test chamber 101 and is used to divide the test chamber 101 into at least two independent chambers along its length. Taking one heat insulation partition 300 as an example, two independent chambers can be divided; taking two heat insulation partitions 300 as an example, three independent chambers can be divided, and so on without limitation.

[0073] The temperature control module of the first temperature control device 201 can be used as a heat source module, while the temperature control module of the second temperature control device 202 can be used as a cold source module. The number of the first temperature control device 201 and the second temperature control device 202 can be varied according to the number of chambers in the actual test. For example, if no partition is set, then only one first temperature control device 201 and one second temperature control device 202 are set. If a partition is set, then two of each of the first temperature control device 201 and the second temperature control device 202 can be set, and so on without limitation.

[0074] The horizontal thermal convection experimental device designed in this application has the following beneficial effects:

[0075] 1. By designing a first temperature control device 201 and a second temperature control device 202 with a first vertical displacement mechanism 21, cold and heat sources can be arranged at the same horizontal height, thereby accurately simulating the horizontal convection process in ocean circulation. This provides an effective model for studying the driving mechanism of ocean circulation (such as the power source of surface warm current driven by high-latitude sinking water flow), and helps to understand the transport mechanism of matter and energy in the ocean and the impact of horizontal convection on ocean heat distribution.

[0076] 2. Both the first temperature control device 201 and the second temperature control device 202 adopt temperature control units 22 that can be separated and assembled and independently controlled, which can realize constant temperature fields or gradual temperature fields of multiple sizes. They can simulate the temperature distribution characteristics of different latitudes and regions in the ocean (such as the temperature gradient between low temperature areas in high latitudes and high temperature areas in low latitudes), meet diverse experimental needs, and help to study in depth the impact of temperature fields on the distribution of marine ecological resources, global heat balance and climate regulation (such as CO2 concentration regulation).

[0077] 3. By designing the heat insulation partition 300, the test chamber 101 can be divided into at least two (same or different lengths) independent chambers, enabling two tests to be carried out simultaneously and each chamber to independently arrange cold and heat sources, significantly improving test efficiency. It can simultaneously compare the horizontal convection effect under different conditions (such as different cold and heat source intensities, different temperature field distributions, and different lengths), accelerate the revelation of the role of the ocean in climate change, the laws of nutrient transport, and its connection with extreme weather events (such as hurricanes), and improve the ability to predict climate events.

[0078] In summary, this technology solves the problem that existing technologies cannot effectively simulate complex ocean circulation processes (driving mechanisms, material and energy transport, etc.), providing a more comprehensive and efficient experimental device for marine science research and meeting the needs for in-depth exploration and accurate prediction of ocean circulation phenomena.

[0079] The above is Embodiment 1 of the horizontal thermal convection test apparatus provided in this application. The following is Embodiment 2 of the horizontal thermal convection test apparatus provided in this application. Please refer to the following for details. Figures 1 to 12 .

[0080] Based on the solution of Embodiment 1 above:

[0081] Furthermore, such as Figure 6 as well as Figure 7 As shown, the temperature control module also includes a heat conduction unit 23. The heat conduction unit 23 can enhance the stability and uniformity of heat exchange between the temperature control unit 22 and the medium in the test chamber 101.

[0082] Specifically, such as Figure 6As shown, several temperature control units 22 can be installed on the heat-conducting unit 23 along the length of the test chamber 101. Specifically, they can be attached to the top surface of the heat-conducting unit 23 or embedded in the top surface of the heat-conducting unit 23. In this case, the heat-conducting unit 23 acts as a whole heat-conducting substrate, uniformly transferring the heat or cold from the multiple temperature control units 22 to the test medium. It can be understood that the heat-conducting unit 23 serves as a support platform for assembling the temperature control units 22, making the assembly of the temperature control units 22 more convenient. The heat-conducting unit 23 can be a heat-conducting copper plate or a plate structure made of other heat-conducting materials. The number of heat-conducting units 23 can be one or more, and the maximum number of temperature control units 22 that can be spliced ​​on a single heat-conducting unit 23 can also be varied according to actual needs, without any specific limitation.

[0083] Or such as Figure 7 As shown, the number of heat-conducting units 23 is the same as that of temperature control units 22. Several temperature control units 22 are correspondingly installed on the heat-conducting units 23. Specifically, they can be attached to the top surface of the heat-conducting unit 23, embedded in the top surface of the heat-conducting unit 23, or embedded inside the heat-conducting unit 23. In this design, each temperature control unit 22 is paired with an independent, combinable heat-conducting unit 23. When combinating, the combination requirements of the temperature control units 22 can be met not only by assembling the heat-conducting units 23, but also by assembling the temperature control units 22 themselves.

[0084] Based on the above design, when simulating adjacent areas in the ocean with large differences in temperature characteristics, a steeper or gentler temperature gradient transition (gradual temperature gradient) can be achieved by adjusting the spacing and power between the temperature control units 22.

[0085] Furthermore, in this application, the number of first vertical displacement mechanisms 21 can be one or more. One first vertical displacement mechanism 21 can drive one temperature control unit 22 or heat conduction unit 23 to move up and down, or one first vertical displacement mechanism 21 can drive multiple temperature control units 22 or heat conduction units 23 to move up and down. Taking a one-to-many design as an example, the lifting end of the first vertical displacement mechanism 21 can be connected via... Figure 5 The connecting bracket 24 shown is connected to the temperature control unit 22 or the heat conduction unit 23.

[0086] The connecting bracket 24 is detachably connected to the temperature control unit 22, the first vertical displacement mechanism 21, or the heat conduction unit 23. This detachable design allows the connecting bracket 24 to be flexibly replaced or adjusted according to the number and size of the temperature control unit 22 or the heat conduction unit 23, enhancing the versatility and ease of maintenance of the device. For example, when it is necessary to replace the temperature control unit 22 with a different specification, it is only necessary to disassemble the connection between the connecting bracket 24 and the original temperature control unit 22 to install the new temperature control unit 22 and re-fix it, without the need for complex modifications to the first vertical displacement mechanism 21 itself.

[0087] Furthermore, such as Figure 5 As shown, taking the connection frame 24 connecting a temperature control unit 22 as an example, the connection frame 24 can be designed to include a connecting block 241 and a guide rod 242; the connecting block 241 is connected to the drive end of the first vertical displacement mechanism 21; the guide rod 242 is vertically connected to the connecting block 241; the first vertical displacement mechanism 21 is fixedly connected to a guide block 213 through which the guide rod 242 moves. The cooperative arrangement of the guide rod 242 and the guide block 213 can provide precise guidance for the lifting and lowering movement of the temperature control module, effectively preventing the temperature control module from shifting or shaking during the lifting and lowering process, ensuring that it can stably and accurately extend into the predetermined position in the test chamber 101, thereby ensuring the accuracy of the cold and heat source application position and improving the reliability of the test results. For example, when simulating the temperature boundary of a specific sea area, the accurate positioning of the temperature control module is crucial for reproducing the real temperature field distribution. The guiding effect of the guide rod 242 and the guide block 213 can effectively eliminate the positional deviation caused by the gap of the lifting mechanism itself or uneven load.

[0088] The design of the first vertical displacement mechanism 21 may include a first vertical actuator 211 and a first mounting bracket. The first mounting bracket may include two first mounting profiles 212, and the first vertical actuator 211 is fixed between the two first mounting profiles 212. The guide block 213 may also be fixed between the two first mounting profiles 212. Preferably, there are multiple guide rods 242, such as two, and the corresponding number of guide blocks 213 is also two, to improve guiding stability. The first vertical actuator 211 may be a telescopic cylinder, an electric push rod, or other telescopic actuator, and there is no specific limitation.

[0089] The connecting block 241 can be detachably connected to the temperature control unit 22 or the heat conduction unit 23 by fasteners such as screws, and can also be detachably connected to the drive end of the first vertical driver 211 by a threaded connection. No specific restrictions are imposed.

[0090] Taking the connecting bracket 24 as an example, which is designed to connect multiple heat-conducting units 23 or multiple temperature control units 22, as follows: Figure 9 As shown, the connecting frame 24 can also be designed to include a fixed rod 243, a first connecting rod 244, and several second connecting rods 245; the fixed rod 243 is arranged along the length direction of the test chamber 101; the first connecting rod 244 is arranged vertically, with one end connected to the fixed rod 243 and the other end connected to the lifting end of the first vertical displacement mechanism 21; the bottom of the fixed rod 243 is provided with a guide rail groove arranged along its own length direction; the second connecting rod 245 is arranged vertically, with one end provided with a sliding fit structure that extends into the guide rail groove and slides with the guide rail groove (the guide rail groove can be a T-shaped groove, and the sliding fit structure can be a T-shaped block that slides with it, and there is no specific limitation), and the other end is used to connect to the temperature control unit 22 or the heat conduction unit 23.

[0091] This structural design allows the second connecting rod 245 to slide flexibly along the length of the fixed rod 243, thereby adjusting the position of the temperature control unit 22 or the heat conduction unit 23 along the length of the test chamber 101 according to experimental requirements. For example, when simulating temperature differences between different latitudes in the ocean, the spacing between each temperature control unit 22 can be changed by sliding the second connecting rod 245 to form a specific temperature field distribution. The sliding fit structure can be a slider, and a positioning screw or clip can be set between the slider and the guide rail groove. After being adjusted to a suitable position, the second connecting rod 245 can be fixed to ensure that the temperature control unit 22 maintains a stable position during the test and avoids affecting the test accuracy due to displacement.

[0092] The sliding fit structure and the guide rail groove can be locked together with locking screws. After adjustment, tightening the locking screws will fix the second connecting rod 245 at a specific position on the fixed rod 243, preventing it from sliding due to vibration or other external forces during the test. In addition, the guide rail groove can be set with scale marks, which makes it easy for operators to accurately control the distance between each second connecting rod 245, and achieve precise control of the temperature field distribution. For example, the position of the temperature control unit 22 can be adjusted according to a preset gradient value (such as a temperature change of 2°C every 10cm), thereby more realistically simulating the temperature gradient characteristics of different areas in the ocean.

[0093] Furthermore, the "one belt, multiple" design can also be implemented without setting up such... Figure 9 Instead of the connecting frame 24 shown, it only drives one of the temperature control units 22 or heat conduction units 23, while the other temperature control units 22 or heat conduction units 23 are rigidly connected to the driven temperature control unit 22 or heat conduction unit 23 through splicing and cooperation, thereby realizing another one-to-many design.

[0094] Specifically, the temperature control unit 22 has a first splicing structure on one side and a second splicing structure that is spliced ​​and cooperates with the first splicing structure on the other side; or, the heat conduction unit 23 has a third splicing structure on one side and a fourth splicing structure that is spliced ​​and cooperates with the third splicing structure on the other side.

[0095] For example, the first splicing structure can be a protrusion, and the second splicing structure can be a groove that fits the protrusion. The engagement of the protrusion and the groove enables the rapid splicing of adjacent temperature control units 22. Alternatively, the first splicing structure can be a snap-fit, and the second splicing structure can be a slot that engages with the snap-fit. The snap-fit ​​is fixed by its elastic deformation engaging into the slot. For the heat conduction unit 23, the third and fourth splicing structures can also adopt similar mechanical matching methods, such as mortise and tenon structures, magnetic components (with positioning guides), etc., to ensure that the connection between each unit is stable after splicing, and to avoid relative displacement caused by the movement of the displacement mechanism or the flow of the medium during the test, which would affect the stability of the temperature field. This splicing design allows the number and arrangement of temperature control units 22 or heat conduction units 23 to be flexibly adjusted according to the length of the test chamber 101 and the required temperature field range to be simulated. For example, when it is necessary to simulate a larger scale of ocean temperature distribution, the number of temperature control units 22 can be increased without replacing the entire temperature control module, effectively reducing the test cost and improving the utilization rate of the device.

[0096] Furthermore, the first splicing structure and / or the second splicing structure are adjustable to make the splicing distance between adjacent temperature control units 22 adjustable;

[0097] Alternatively, the third and / or fourth splicing structures can be extended and adjusted to make the splicing distance between adjacent heat-conducting units 23 adjustable.

[0098] This scalable and adjustable splicing structure allows for a continuously adjustable spacing range between the temperature control unit 22 or the heat conduction unit 23. Combined with the independent temperature control function of each temperature control unit 22, it is possible to flexibly construct temperature fields with different spatial resolutions. For example, it can simulate the complex temperature distribution characteristics in the ocean, where the temperature changes gently near the equator (large unit spacing) and the temperature changes dramatically near the polar regions (small unit spacing), further enhancing the device's ability to simulate real marine environments.

[0099] Taking the scalable design of the second and fourth splicing structures as an example, the following is an application example:

[0100] Specifically, such as Figure 8 As shown, both the first and third splicing structures can be sockets 31, and both the second and fourth splicing structures can be rods 32. One end of the rod 32 can be inserted into the socket 31 and has an interference fit with it. The telescopic design of the rod 32 can be in two ways: one is to adjust the distance at which one end extends out of the temperature control unit 22 or heat conduction unit 23 through its own telescopic control; the other is to adjust the distance at which one end extends out of the temperature control unit 22 or heat conduction unit 23 by moving it. Figure 6As shown, taking mobility as an example, a fixing block 33 can be designed on one side of the top or bottom of a temperature control unit 22 or a heat conduction unit 23. The fixing block 33 has a threaded hole 34, and the insertion rod 32 passes through the threaded hole 34 and is threadedly connected to the threaded hole 34.

[0101] like Figure 8 As shown, the extension length of the insert rod 32 can be adjusted by rotating it, thereby changing the splicing distance between adjacent temperature control units 22 or heat conduction units 23. For example, when simulating a small temperature gradient in a certain area of ​​the ocean, the insert rod 32 can be unscrewed to increase the unit spacing; when simulating a large temperature gradient, the insert rod 32 can be screwed in to decrease the unit spacing. This threaded connection method is not only convenient to adjust, but also maintains a stable spacing through thread self-locking after adjustment, ensuring the accuracy of the temperature field during the experiment. In addition, an elastic washer can be set on the inner wall of the insertion hole 31. When the insert rod 32 is inserted, the washer is compressed to generate friction, further enhancing the stability after splicing and preventing the insert rod 32 from loosening due to vibration during device operation, which would cause changes in the spacing.

[0102] Furthermore, such as Figure 3 As shown, both the first temperature control device 201 and the second temperature control device 202 further include a first horizontal displacement mechanism 26; the first horizontal displacement mechanism 26 is connected to the first vertical displacement mechanism 21 and is used to drive the first vertical displacement mechanism 21 to move along the length direction of the test chamber 101. Through the arrangement of the first horizontal displacement mechanism 26, the temperature control module can not only adjust the contact depth with the test medium in the vertical direction, but also adjust its overall position along the length direction of the test chamber 101. This design greatly expands the flexibility of temperature field simulation to adapt to the needs of different test section lengths.

[0103] like Figure 4 as well as Figure 5 As shown, taking the example of having rails 13 on both sides of the top of the test chamber 101 on the main body of the device, the first horizontal displacement mechanism 26 can be designed to include a second mounting frame and a first horizontal slider. The second mounting frame can include two second mounting profiles 261, and two first mounting profiles 212 are vertically mounted on the two second mounting profiles 261. The number of first horizontal sliders 262 can be four, which are arranged in pairs at the bottom ends of the second mounting profiles 261 and slidably mounted on the rails 13 to realize manual horizontal displacement adjustment. Of course, a first horizontal driver, such as an electric push rod, can be added to connect to the second mounting frame and drive the second mounting frame to slide on the rails 13 to realize electric horizontal displacement adjustment. The specific design is not limited.

[0104] The manual horizontal displacement adjustment can be achieved by adding a tightening screw. The tightening screw is threaded onto the first horizontal displacement mechanism 26. After the sliding adjustment is in place, the tightening screw is rotated to tighten the device body, thereby locking the position of the first horizontal displacement mechanism 26. This prevents the temperature control module from undergoing horizontal displacement due to factors such as vibration or medium flow during the test, and ensures the stability of the temperature field application position.

[0105] like Figure 2 As shown, both the first temperature control device 201 and the second temperature control device 202 may further include a first protective housing 25. The first protective housing 25 is mounted on the second mounting bracket and can cover and protect the first vertical displacement mechanism 21, thereby improving the protection effect.

[0106] In this application, the temperature control unit 22 of the first temperature control device 201, which serves as a heat source, can be a programmable temperature-controlled heating element, an electric heating wire, or a flow channel heat exchange plate, etc. Its temperature control range can be set according to the test requirements, such as from room temperature to 150℃, and the temperature control accuracy can reach ±0.05℃, ensuring the stability of the heat source output.

[0107] The temperature control unit 22 of the second temperature control device 202, which serves as the cold source, can be a cooling chip, a flow-channel heat exchange plate, etc. The design of the flow-channel heat exchange plate allows for more precise temperature regulation and more uniform heat exchange by controlling the flow rate and temperature of the fluid, making it particularly suitable for experimental scenarios requiring the simulation of large-scale, stable temperature fields. For example, when simulating the convergence of the equatorial warm current and the polar cold current, using a flow-channel heat exchange plate as the cold / heat source temperature control unit 22 allows for the precise reproduction of the complex temperature distribution and energy exchange process at the confluence of ocean currents by adjusting the temperature and flow rate of the fluid in different regions of the flow channel.

[0108] Of course, the above-mentioned temperature control types are not the only ones that can be modified or adjusted according to actual needs.

[0109] Furthermore, such as Figure 11As shown, the device also includes a thermal insulation cover assembly 700; the thermal insulation cover assembly 700 includes an adjusting frame 41 and a cover plate 42; the cover plate 42 is disposed in the test chamber 101 and is located above the static water level or in contact with the water surface (the static water level refers to the equilibrium liquid level height of the free surface of the test medium in the test chamber 101 when it is not disturbed by external forces); the adjusting frame 41 is connected between the cover plate 42 and the device body and is used to adjust the height of the cover plate 42. The cover plate 42 is preferably made of a thermal insulation material with low thermal conductivity, such as polycarbonate sheet, which is covered with a heat insulation film (porous vacuum silicon super heat insulation film). The cover plate 42 can effectively block the heat exchange between the inside and outside of the test chamber 101 and reduce the interference of ambient temperature on the temperature field of the test medium. For example, during long-term horizontal thermal convection tests, the thermal insulation cover assembly 700 can significantly reduce the heat loss in the test chamber, ensure that the temperature boundary conditions applied by the cold and heat sources remain stable, thereby improving the accuracy and repeatability of the test data.

[0110] Multiple insulation cover components 700 can be designed and can be detachably connected to the device body. This allows for the selection of an appropriate number based on the assembly length of the temperature control module, covering and insulating the area outside the temperature control module. The detachable design also facilitates installation and disassembly.

[0111] Two cover plates 42 can be provided in the heat insulation cover assembly 700. The two cover plates 42 are arranged at intervals along the width direction of the test chamber 101, and the gap formed in the middle can provide passage for the detection device to facilitate temperature detection inside the test chamber 101.

[0112] Multiple adjustment frames 41 are provided, with at least one installed on each cover plate 42. The adjustment frame 41 can be a manually operated lifting frame, such as including a first L-shaped frame 411 and a second L-shaped frame 412. The first L-shaped frame 411 and the second L-shaped frame 412 are fixed to the cover plate 42. The first L-shaped frame 411 has an elongated hole, and the second L-shaped frame 412 has a through hole that mates with the elongated hole. Bolts pass through the through hole and the elongated hole and are connected with nuts to fasten the first L-shaped frame 411 and the second L-shaped frame 412 together. The first L-shaped frame 411 is detachably connected to the device body. By loosening the nuts and moving the second L-shaped frame 412 up and down along the elongated hole, the height of the cover plate 42 can be adjusted so that it is above the static water level of the test medium or in contact with the water surface, ensuring the heat preservation effect without interfering with the natural convection of the test medium. The length of the elongated orifice can be designed according to the maximum liquid level variation range of the test chamber 101, for example, by setting an adjustment stroke of 10cm to adapt to the liquid level adjustment requirements under different test conditions.

[0113] Furthermore, such as Figure 2 , Figure 3 as well as Figure 10As shown, a track 13 is provided on the main body of the device along the length direction of the test chamber 101; a plurality of second horizontal displacement mechanisms 14 that move along the track 13 are installed on the track 13; the detection device 400 includes a plurality of temperature sensors 401 that extend into the test chamber 101; each of the second horizontal displacement mechanisms 14 is connected to the temperature sensor 401 in a one-to-one correspondence, and can drive the connected temperature sensor 401 to move along the length direction of the test chamber 101.

[0114] The second horizontal displacement mechanism 14 moves the temperature sensor 401 along the track 13, enabling dynamic monitoring and acquisition of temperatures at different locations within the test chamber 101. This allows for precise capture of the spatial distribution characteristics and temporal variations of the temperature field. For example, in simulating horizontal convection in ocean circulation, it can track in real-time temperature gradient changes, heat diffusion rates, and temperature stratification at different depths (adjusted by combining the height of the temperature sensor 401 with the first vertical displacement mechanism 21). This provides detailed data support for analyzing the intensity, range, and impact of horizontal convection on the surrounding environment. Simultaneously, multiple second horizontal displacement mechanisms 14 can independently control different temperature sensors 401, enabling multi-point synchronous measurement. This avoids the limitations of single-point measurement, providing a more comprehensive view of the temperature field within the entire test chamber 101 and further improving the accuracy and reliability of the experimental data.

[0115] The second horizontal displacement mechanism 14 can be a linear trolley that can slide controllably on the track 13. Its sliding control system can be driven by a high-precision servo motor and used in conjunction with a grating ruler or encoder for position feedback to achieve precise control with a displacement accuracy of ±0.1mm, ensuring that the temperature sensor 401 can be accurately positioned at the preset measurement point.

[0116] like Figure 10 As shown, the linear trolley can also be a manual trolley structure, which specifically includes a trolley frame 141 and a pulley 142 installed at the bottom of the trolley frame 141 and slidingly engaged with the track 13. The trolley frame 141 can be manually slid to achieve horizontal displacement adjustment. After sliding, the trolley frame 141 can also be locked on the track 13 by tightening screws or buckles to prevent it from moving accidentally during the test.

[0117] The temperature sensor 401 can be a high-precision miniature thermistor. Its compact size allows it to penetrate the gap between the temperature control module and the test chamber 101, or between adjacent temperature control modules, or between adjacent cover plates 42, to measure temperatures at specific points within the test chamber 101. It also features a fast response time, capturing minute temperature changes in a short period, meeting the monitoring requirements for transient temperature fields during horizontal convection. The thermistor's measurement accuracy reaches ±0.05℃, ensuring the accuracy of temperature data and providing reliable parameters for analyzing heat transport and temperature gradient distribution in ocean circulation. Simultaneously, it exhibits good stability and anti-interference capabilities, maintaining stable measurement performance even when the medium flows within the test chamber 101 or external environmental factors fluctuate, preventing fluctuations in sensor characteristics from affecting the accuracy of experimental results. Furthermore, high-precision miniature thermistors typically have a wide measurement range, such as -50℃ to 150℃, adapting to different temperature conditions that may occur in marine environment simulations. Whether simulating the high-temperature environment of tropical seas or the low-temperature environment of polar seas, it can accurately sense and report temperature information.

[0118] In addition, the track 13 of this application can be arranged in a variety of ways. One way is to lay it on the edge of the opening of the test chamber 101, and the first temperature control device 201, the second temperature control device 202 and the second horizontal displacement mechanism are all installed on the track 13.

[0119] The track 13 can also be suspended above the opening edge of the test chamber 101 and supported and fixed by another bracket. Of course, it is not limited to the above method. Those skilled in the art can make changes according to actual needs without restriction.

[0120] Alternatively, two sets of tracks 13 can be provided, arranged vertically. The upper set is used to slide and mount the first temperature control device 201 and the second temperature control device 202. This design allows the second horizontal displacement mechanism 14 to move the temperature sensor 401 freely along the entire length of the test chamber 101, achieving comprehensive monitoring of the temperature field within the test chamber 101 without blind spots. For example, when simulating the temperature distribution of a narrow sea area, the track 13, which extends the entire length, allows the temperature sensor 401 to move from one end of the test chamber 101 to the other, continuously collecting temperature data from different locations, thereby plotting a complete temperature field distribution curve. This is crucial for studying the temperature variation patterns of long-distance ocean currents.

[0121] In addition, the design of the two sets of tracks 13 also ensures that the horizontal movement adjustment of the first temperature control device 201 and the second temperature control device 202 is not affected by the second horizontal displacement mechanism 14. When it is necessary to move the temperature field as a whole to the left or right side of the test chamber 101, there is no need to disassemble part of the second horizontal movement mechanism, which greatly simplifies the adjustment process of the test setup.

[0122] Furthermore, such as Figure 10 As shown, a second vertical displacement mechanism 15 is mounted on the second horizontal displacement mechanism 14; the second vertical displacement mechanism 15 is connected to the temperature sensor 401 and is used to adjust the height of the temperature sensor 401 in the test chamber 101. Figure 2 As shown, a second protective shell 152 can also be provided and installed on the second horizontal displacement mechanism 14 to cover and protect the second vertical displacement mechanism 15. No specific restrictions are imposed.

[0123] The second vertical displacement mechanism 15 can be an electric cylinder, telescopic rope, or other mechanism capable of lifting and lowering control. Taking the telescopic rope mechanism as an example, a servo motor-driven winding wheel structure can be used. By precisely controlling the number of rotations of the winding wheel, the length of the rope can be adjusted, thereby achieving precise positioning of the temperature sensor 401 in the height direction of the test chamber 101. The adjustment accuracy can reach ±0.1mm, meeting the simulation monitoring needs of different water depth temperature environments. For example, when studying the vertical temperature stratification phenomenon in the ocean, the temperature sensor 401 can be gradually lowered through the second vertical displacement mechanism 15 to collect temperature data layer by layer from the surface seawater to the deep sea area, clearly showing the law of water temperature change with increasing depth, such as the specific depth and temperature change range of the thermocline. The rope can be made of high-strength, low-elastic deformation nylon rope or stainless steel wire rope to ensure that it is not easily stretched or deformed under long-term use and load, ensuring the accuracy of the height measurement of the temperature sensor 401. Meanwhile, a guide wheel 151 can be installed on the second vertical displacement mechanism 15 to change the direction of force on the rope and reduce friction, ensuring that the temperature sensor 401 moves smoothly and without shaking during the lifting and lowering process. In addition, the second vertical displacement mechanism 15 can also be equipped with a length encoder to provide real-time feedback on the lowering depth of the temperature sensor 401 and transmit the data synchronously to the control system, realizing precise closed-loop control of the three-dimensional spatial position of the temperature sensor 401, and providing strong support for the spatial positioning analysis of experimental data.

[0124] Furthermore, such as Figure 2 As shown, the device body design includes a test tank 100; the test tank 100 includes a tank frame 11 and a heat insulation plate 12 installed on the tank frame 11; the heat insulation plate 12 installed on the tank frame 11 forms a test chamber 101.

[0125] Specifically, the heat insulation panel 12 is vacuum glass; the vacuum layer of the vacuum glass is provided with a support structure.

[0126] The vacuum glass insulation panel 12 effectively blocks heat exchange between the inside and outside of the test chamber 101, minimizing the impact of ambient temperature on the water temperature inside the chamber and providing a stable temperature environment for the study of temperature stratification. The supporting structure cleverly bears the load between the glass panes, preventing deformation or damage due to atmospheric pressure under vacuum conditions. This ensures the integrity of the vacuum layer, guarantees the long-term stability of the insulation performance, and enhances the structural strength and service life of the insulation panel 12, enabling the test chamber 100 to operate stably for extended periods.

[0127] Furthermore, such as Figure 1 As shown, the device body also includes a protective cover 600; the protective cover 600 covers the outside of the test tank 100.

[0128] The protective cover 600 serves several purposes. First, it reduces air exchange between the inside and outside of the cover, preventing disturbances such as movement of people or air conditioning from affecting the air inside. This maintains a relatively stable internal environment within the cover 600 and further reduces the potential interference of external airflow with the temperature field inside the test chamber 101.

[0129] Secondly, the protective cover 600 can also be made of insulating material, forming an air insulation layer between it and the test chamber 100. Together with the heat insulation plate 12 of the vacuum glass, it constitutes a double heat insulation barrier, further improving the insulation performance of the device and effectively preventing the temperature inside the test chamber 101 from escaping through the chamber wall or the external ambient temperature fluctuations from interfering with the test chamber 101. The protective cover 600 can be made of high-efficiency insulating materials such as polyurethane foam or polystyrene foam board, and a reflective layer (such as aluminum foil) can be added to its inner side to reduce heat transfer by reflecting heat radiation. The protective cover 600 can be equipped with an observation window, which adopts a double-layer vacuum glass structure. Under the premise of ensuring the insulation effect, it is convenient for operators to observe the situation inside the test chamber 101 in real time, such as the medium flow status and the working status of the temperature control unit 22.

[0130] Of course, the protective cover 600 can also be a frame + glass design. The above design facilitates observation of the situation inside the test chamber 101. An insulation film or insulation cotton layer can be added to the outer layer of the glass to meet observation needs while also ensuring insulation performance. For example, using Low-E low-emissivity coated glass as the glass part of the protective cover 600 can effectively reflect infrared heat radiation and reduce the transfer of heat from the test chamber 101 to the outside. The insulation film can be a multi-layered nano-insulation film to further improve the heat insulation coefficient of the glass. This frame + glass design allows the entire device to provide a comprehensive visual observation perspective while having good insulation performance. This makes it easy for researchers to intuitively observe the formation and evolution of the temperature field and the flow state of the medium inside the test chamber 101, providing convenience for the analysis and recording of experimental phenomena.

[0131] In addition, water supply pipes can be added to connect the test chamber. There can be multiple water supply pipes to ensure that each chamber separated by the heat insulation partition 300 can be connected to a water supply pipe, thereby achieving water replenishment and drainage control.

[0132] Furthermore, such as Figure 1 , Figure 2 As shown, the device body also includes a support platform 500; a heat insulation pad (not shown in the figure) is provided on the support platform 500; and the test tank 100 is disposed on the heat insulation pad.

[0133] The support platform 500 provides a stable foundation for the entire device, ensuring the stability of the device itself during the test and preventing the uniformity of the temperature field and the accuracy of the measurement data from being affected by device shaking. The heat insulation pad is made of high-temperature resistant, low thermal conductivity materials, such as silicone heat insulation pads or asbestos boards. It is placed between the support platform 500 and the test tank 100, which can effectively block heat transfer between the support platform 500 and the test tank 100. It prevents heat from the bottom of the test tank 100 from being lost to the outside through the support platform 500, or heat from the outside environment from being conducted to the test tank 100 through the support platform 500, further optimizing the thermal insulation performance of the device and providing a more reliable guarantee for the precise control of the temperature field inside the test chamber 101.

[0134] Furthermore, such as Figure 12 As shown, an airbag-type sealing strip 301 is provided on the side of the heat insulation partition 300 that contacts the inner wall of the test chamber 101.

[0135] The airbag-type sealing strip 301 is made of elastic rubber material resistant to high and low temperatures and filled with inert gas. When the heat insulation partition 300 is installed, the airbag-type sealing strip 301 fits tightly against the inner wall of the test chamber 101, filling the tiny gaps between them through its own elastic deformation, forming the first sealing barrier. Simultaneously, the inert gas inside the airbag further hinders heat convection, working synergistically with the heat insulation performance of the heat insulation partition 300 to significantly reduce heat exchange between different areas of the test chamber 101, ensuring the independence and stability of the temperature in each area and providing a more precise temperature environment for the test. The heat insulation partition 300 is a partition plate and can be made of vacuum glass or other heat insulation materials; there are no restrictions.

[0136] The horizontal thermal convection test apparatus provided in this application has been described in detail above. For those skilled in the art, there may be changes in the specific implementation method and application scope based on the ideas of the embodiments of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
