Description

Technical Field

[0001] This application belongs to the field of experimental equipment technology, and more specifically, relates to a multi-environment field coupling experimental cabinet. Background Technology

[0002] In biological research, unconventional environmental conditions are often required to study the unique responses of organisms under different environments. For example, strong static magnetic fields have a wide-ranging impact on plant gene expression. [1] Electrostatic fields can affect the growth of microorganisms. [2,3] It can also directly affect the growth and development of plants. [4] Meanwhile, research on plant gravitropism has now penetrated to the cellular, genetic, and molecular levels. [5,6] Among these, there are instances where different growth stages and parts of the same plant respond differently to gravity. [7] Therefore, further research will also lead to the need to tilt or lay the plants horizontally.

[0003] For example, for aquatic organisms, especially those living in deep-water, high-pressure environments, people can now design and manufacture special devices to conduct deep-water sampling and even in-situ experiments, and have discovered their response to pressure changes. Researchers hope to conduct research while maintaining in-situ pressure. [8] Similarly, terrestrial organisms also exhibit response behaviors to changes in pressure; for example, studies have been conducted on the reactions of common crops under high pressure. [9] .

[0004] Because water is a conductor, electromagnetic waves are easily attenuated within it; for example, the depth limit of visible light in sunlight is only about 200 meters. Therefore, aquatic organisms rely primarily on sound waves to receive and react to information, except for direct contact with chemical substances in the water and, in a few cases, bioluminescence. This is especially true for complex and dense information flows; for example, whales use sound waves to precisely locate obstacles, food, and signs of danger. Furthermore, sound waves in water also have a certain impact on the metabolism, growth, and development of organisms.

[10] Therefore, studying the reactions of organisms to specific sound waves is a worthwhile environmental condition to explore. For terrestrial organisms, the effects of sound waves are even more prevalent, forming various complex environmental conditions together with light.

[0005] Existing experimental equipment makes it difficult to integrate the various experimental conditions described above. Testing organisms in different suitable environments requires multiple devices to conduct separate experiments for each environment, which is cumbersome. Furthermore, in actual experiments, it is often necessary to simultaneously combine multiple environments, such as electric fields and tilted gravitational fields, or high voltage and magnetic fields. Due to the high complexity of living organisms, the effects produced by simply combining the responses of a single condition with those produced by coupling multiple conditions often differ or are even completely different. Therefore, the preparation of complex environmental conditions is of great significance.

[0007] To address the shortcomings of existing technologies, this application provides a multi-environment field coupling experimental cabinet that can integrate various environmental conditions to study the response phenomena of experimental subjects under various single or composite environments.

[0008] To achieve the above objectives, the technical solution of this application provides a multi-environment field coupling experimental cabinet, including a cabinet, an electromagnetic field generator, a temperature control device, a sound wave generator, an irradiation lamp, a pneumatic pump, a power supply, and a human-machine interface; the cabinet has an experimental chamber with a sealed door, an experimental platform is installed inside the experimental chamber, the experimental platform is horizontally rotatably mounted on the bottom wall of the experimental chamber, the top of the experimental platform has a sample space for accommodating the sample to be tested, the electromagnetic field generator has electromagnetic coils arranged opposite to each other on both sides of the sample space and electrode plates arranged opposite to each other on both sides of the experimental platform, the temperature control device is installed in the experimental chamber, the sound wave generator and the irradiation lamp are both installed in the experimental chamber and oriented towards the sample space, and the port of the pneumatic pump is connected from the outside of the experimental chamber to the experimental chamber; the electromagnetic field generator, temperature control device, sound wave generator, irradiation lamp and pneumatic pump are all connected to the power supply and the human-machine interface.

[0009] The sample is fixed on the experimental stage and located within the sample space. The stage can be rotated to adjust the sample's orientation. The electric field, magnetic field, temperature, acoustic, light, and air pressure environments within the experimental chamber can be adjusted individually and coupled to each other, enabling the detection of sample responses under complex coupled conditions. However, it's important to note that not all environments can be coupled; for example, electric and magnetic fields may not occur simultaneously. The experimenter should selectively superimpose these environments based on the required detection conditions. This multi-environment coupling experimental chamber can be used for the detection of terrestrial, aquatic, and microbial organisms, as well as for non-biological samples such as the response of a substance under different environments.

[0010] Optionally, a water tank is also provided, placed on top of the experimental platform, with the sound generator placed inside. This allows for experiments on samples in the water. The electric field, magnetic field, temperature, light, and air pressure in the water can all be applied through corresponding equipment outside the water tank, but sound waves are difficult to propagate completely from the air into the water; therefore, the sound generator is placed inside the water tank.

[0011] Optionally, the sound generator is installed on the inner wall of the experimental chamber and positioned facing the experimental platform, so that sound waves can be applied to samples in non-aqueous bodies.

[0012] Optionally, the experimental platform is also equipped with a stage; the stage includes a base, a hinge shaft and a sample carrier stage. The sample carrier stage is rotatably mounted on the top of the base via the hinge shaft. The top of the experimental platform has several connecting screw holes, and the base is bolted to any of the connecting screw holes. The top of the sample carrier stage has several mounting screw holes.

[0013] The stage can be bolted to any of the connecting screw holes on the experimental platform, allowing for adjustment of its position. The sample support stage is used to hold the sample. The sample support stage can be hinged and tilted up and down to adjust its angle. This tilt adjustment, combined with the rotation of the experimental platform itself, allows for adjustment of the sample's position and angle in space to simulate different gravitational directions. This enables the study of the response phenomena of samples under different environmental conditions applied in an inclined gravitational direction.

[0014] Optionally, the experimental chamber is also equipped with a humidity control device, and a UV lamp facing the experimental table is installed inside the chamber. Both the humidity control device and the UV lamp are connected to a power supply and a human-machine interface. The humidity control device is used to regulate the ambient humidity to enhance the controllability of humidity conditions. The UV lamp emits ultraviolet light onto the sample to enhance the research conditions in the UV environment. The operator controls the intensity of the humidity control device and the UV lamp through the human-machine interface.

[0015] Optionally, the electromagnetic field generator includes four sets of electromagnetic field units, each with an electromagnetic coil and an electrode plate. Two sets of electromagnetic field units serve as horizontal electromagnetic field units, and the other two sets serve as vertical electromagnetic field units. The two sets of horizontal electromagnetic field units are located on both sides of the horizontal position of the sample space and are arranged opposite to each other. The two sets of vertical electromagnetic field units are located on the upper and lower sides of the sample space and are arranged opposite to each other. A hollow support is installed on the bottom wall of the experimental chamber, and a turntable is installed on the top of the hollow support. The experimental chamber is fixedly connected to the turntable. The vertical electromagnetic field units located at the bottom of the sample space are installed inside the hollow support and on the bottom wall of the experimental chamber, and the vertical electromagnetic field units located at the bottom of the sample space are installed on the top wall of the experimental chamber.

[0016] This setup allows the magnetic and electric fields to be configured in both horizontal and vertical directions, enabling the testing and study of different response phenomena of samples when subjected to electric or magnetic fields in two different directions under gravity. The perforated support not only ensures the installation of the experimental stage but also provides space for the installation of a vertical electromagnetic field unit located at the bottom of the sample space.

[0017] Optionally, in each electromagnetic field unit, a non-magnetically insulating plate is fixed to the end of the electromagnetic coil facing the sample support stage. The non-magnetically insulating plate is provided with a slot, and the end of the slot has a contact terminal for connection with the power supply and human-machine interface. The electrode plate can be detachably inserted into the slot and electrically connected to the contact terminal.

[0018] In actual experiments, electric and magnetic field environments will not occur simultaneously. In environments requiring a magnetic field, the electrode plate can be removed from its slot to avoid it affecting the magnetic field. Furthermore, the non-magnetically insulating plate will not affect the distribution of the magnetic field. In environments requiring an electric field, the electrode plate is inserted into its slot and a voltage is applied through the contact terminals. The non-magnetically insulating plate prevents the electrode plate from being electrically connected to the core of the electromagnetic coil and thus avoiding any interference.

[0019] Optionally, both sets of horizontal electromagnetic field units are horizontally slidably arranged within the experimental chamber. These units can be moved closer to or further away from the sample space by sliding, allowing adjustment of the distance between them to regulate the electric and magnetic field strengths. The magnitudes of the magnetic and electric fields can also be adjusted using current and voltage.

[0020] Optionally, telescopic devices are installed on both horizontal side walls of the experimental chamber. Each telescopic device includes a fixed sleeve and a sliding sleeve. One end of the fixed sleeve is fixedly installed on the side wall of the experimental chamber, and the sliding sleeve is slidably fitted onto the end of the fixed sleeve away from the side wall of the experimental chamber. The horizontal electromagnetic field unit is fixedly connected to the end of the sliding sleeve away from the fixed sleeve. A telescopic scale is provided along the extension direction of the sliding sleeve. By sliding the sliding sleeve along the fixed sleeve, the horizontal position of the horizontal electromagnetic field unit can be adjusted. The telescopic scale allows for quantitative adjustment of the position.

[0021] Optionally, the cabinet also includes an equipment compartment, and the temperature control device includes an outdoor air conditioner unit and an indoor air conditioner unit. The outdoor air conditioner unit is located in the equipment compartment, and the heat dissipation end of the outdoor air conditioner unit extends out of the cabinet. The indoor air conditioner unit includes evaporator pipes, which are distributed in a serpentine pattern on the inner wall of the experimental compartment. The side wall of the experimental compartment has a heat insulation layer. The air pressure pump is located in the equipment compartment.

[0022] The equipment compartment is used to install equipment not located within the experimental chamber. A temperature control device regulates the temperature inside the experimental chamber. Insulation reduces heat loss between the experimental chamber interior, evaporator piping, and the environment, improving thermal efficiency. Evaporator piping distributed along the inner wall of the experimental chamber ensures temperature uniformity within the chamber. A pressure pump allows for the regulation of the internal pressure environment of the experimental chamber.

[0023] The advantages of the technical solution in this application compared to the prior art are as follows: The sample is placed in the sample space and fixed on the experimental stage. The operator, via a human-machine interface, can control the electric field, magnetic field, temperature, sound, light, and air pressure environments within the experimental chamber through an electromagnetic field generator, temperature control device, sound wave generator, irradiation lamp, and air pressure pump. These experimental environments can be coupled to achieve multi-environment coupling, allowing for the detection of the sample's response under complex coupled conditions. Compared to existing separate tests, this method reduces the number of experimental devices and enables the observation of the combined effects of multiple coupled conditions on the sample.

[0024] This multi-environment coupling experimental cabinet can be used for the detection of terrestrial organisms, aquatic organisms, and microorganisms, as well as for the response phenomena of non-biological samples, such as a certain substance, under different environmental conditions. This multi-environment coupling experimental cabinet can also be used to test the stability of a device under specific environmental conditions, such as placing the device to be tested in a sample space to study whether the device can operate stably in high and low temperature, high and low pressure, electric field, and magnetic field environments.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] Example 1: This embodiment provides a multi-environmental field coupling experimental cabinet, based on... Figure 1As shown, the system includes a cabinet 1, an electromagnetic field generator, a temperature control device, a sound wave generator 2, an irradiation lamp 31, a pneumatic pump 4, a power supply, and a human-machine interface 5. The cabinet 1 has an experimental chamber 11 with a sealed door located on the front side of the cabinet 11 (not shown in the attached diagram). An experimental platform 12 is installed inside the experimental chamber 11, horizontally rotatably mounted on the bottom wall of the chamber 11. The top of the platform 12 has a sample space 14 for accommodating the sample to be tested. When the sample is placed on the platform 12, it is positioned in the sample space 14, and the platform 12 can be rotated to adjust the sample's orientation. The electromagnetic field generator has electromagnetic coils 611 positioned opposite each other on both sides of the sample space 14 and electrode plates 612 positioned opposite each other on both sides of the platform 12. The "both sides" can represent either horizontal or vertical directions. The opposing electromagnetic coils 611 generate a magnetic field during the experiment, exposing the sample to the magnetic field environment. The opposing electrode plates 612 generate an electric field during the experiment, exposing the sample to the electric field environment. The temperature control device is installed in the experimental chamber 11. The sound wave generator 2 and the irradiation lamp 31 are both installed in the experimental chamber 11 and are oriented towards the sample space 14. The port of the air pressure pump 4 is connected from the outside of the experimental chamber 11 to the experimental chamber 11. The electromagnetic field generator, temperature control device, sound wave generator 2, irradiation lamp 31 and air pressure pump 4 are all connected to the power supply and human-machine interface 5.

[0030] Operators can adjust the environment within the experimental chamber 11 via the human-machine interface 5. The electric and magnetic field environments within the experimental chamber 11 are adjusted via an electromagnetic field generator, the temperature environment via a temperature control device, the sound environment via a sound wave generator 2, the illumination environment via an irradiation lamp 31, and the pressure environment via a pressure pump 4. The electric, magnetic, temperature, sound, illumination, and pressure environments can be adjusted individually and coupled to achieve multi-environment coupling, allowing for the detection of sample response phenomena under complex coupled environments. However, it should be noted that not all environments can be coupled; for example, electric and magnetic field environments may not occur simultaneously. Experimenters should selectively superimpose these experimental environments according to the actual required detection conditions. This multi-environment coupling experimental cabinet can be used for the detection of terrestrial organisms, aquatic organisms, and microorganisms, as well as for the response phenomena of non-biological samples, such as a substance, under different environments. This multi-environment coupling experimental cabinet can also be used to test the stability of a device under specific environments. For example, the device to be tested can be placed in the sample space 14 to study whether the device can operate stably under high and low temperature, high and low pressure, electric field, and magnetic field environments. Correspondingly, the experimental chamber 11 needs to be equipped with a power outlet to provide a power interface for the device being tested.

[0031] Correspondingly, the experimental chamber 11 in this embodiment is equipped with an electric field strength sensor, a magnetic field strength sensor, a temperature sensor, a sound sensor, a light sensor, and a pressure sensor, all connected to the human-machine interface 5, so that operators can monitor the environment inside the experimental chamber 11 in real time through the human-machine interface 5. The electric field strength sensor, magnetic field strength sensor, sound sensor, and light sensor need to extend into the sample space 14 to ensure that the measured results are consistent with the corresponding field strength received by the sample. Since the temperature and pressure are relatively consistent throughout the experimental chamber 11, the temperature and pressure sensors can be directly mounted on the side wall of the experimental chamber 11. However, for better measurement accuracy, the temperature and pressure sensors can also be extended into the sample space 14.

[0032] In this embodiment, the multi-environmental field coupling experimental cabinet is used to study the reaction phenomena of aquatic organisms under various environmental field coupling conditions, and therefore a water tank 8 is also provided. The water tank 8 is placed on the top of the experimental platform 12. To ensure the stability of the water tank 8, it can also be fixed to the experimental platform 12 by bolts or clips. The sound wave generator 2 is placed inside the water tank 8. In this embodiment, the sound wave generator 2 is directly installed on the side wall of the water tank 8. In other embodiments, the sound wave generator 2 can also be installed on the top wall of the experimental chamber 11 by a telescopic rod. When the water tank 8 is placed on the experimental platform 12, the telescopic rod extends to lower the sound wave generator 2 into the water body of the water tank 8. The electric field environment, magnetic field environment, temperature, light environment and air pressure in the water body can be applied by corresponding equipment outside the water tank 8, but the sound wave environment is difficult to propagate completely from the air into the water body, so the sound wave generator 2 is placed inside the water tank 8. The electric field strength sensor, magnetic field strength sensor, sound sensor, light sensor, temperature sensor, and pressure sensor all extend out of the experimental chamber 11 via wires and are connected to the human-machine interface 5. After the water tank 8 is placed on the experimental platform 12, the detection ends of the electric field strength sensor and the magnetic field strength sensor can be attached and fixed to the outer wall of the water tank 8, while the detection ends of the sound sensor, light sensor, temperature sensor, and pressure sensor can be attached and fixed to the inner wall of the water tank 8 and submerged in the water.

[0033] To enable real-time observation of changes in the sample during the experiment, a camera 10 can be installed on the inner wall of the experimental chamber 11, facing the sample space 14. The camera 10 can be installed at any location, such as the top wall or the front and rear side walls of the experimental chamber 11, and its orientation and number can be arbitrarily set according to the actual experimental observation needs. The camera 10 is connected to the human-machine interface 5, and the image can be transmitted to the display of the human-machine interface 5 in real time.

[0034] Example 2: This embodiment provides a multi-environment field coupling experimental cabinet, which differs from Embodiment 1 in that it is used to detect samples in non-aquatic bodies. Therefore, based on Figure 2As shown, the water tank 8 is no longer set up. The sound wave generator 2 is installed on the inner wall of the experimental chamber 11 and is set towards the experimental platform 12, so that sound waves can be applied to samples in non-aqueous bodies.

[0035] In detail, based on Figures 2 to 4 As shown, the experimental platform 12 is also equipped with a stage 13. The stage 13 includes a base 131, a hinge shaft 132, and a sample support stage 133. The sample support stage 133 is used to place the sample, and its top serves as the sample space 14. The sample support stage 133 is rotatably mounted on the top of the base 131 via the hinge shaft 132. The sample support stage 133 can swing up and down via the hinge to adjust its tilt angle. This tilt angle adjustment, combined with the rotation of the experimental platform 12 itself, allows for adjustment of the sample's position and angle in space to simulate different gravitational directions, enabling the study of the response phenomena when different environmental conditions are applied to the sample under tilted gravitational direction conditions.

[0036] Specifically, in this embodiment, the top of the base 131 has two symmetrically arranged support walls 139, and the bottom of the sample support stage 133 has two symmetrically arranged hinge walls 1310. The two hinge walls 1310 are respectively attached to the two support walls 139 and are hinged through a hinge shaft 132. The hinge shaft 132 can be a bolt. After the tilt angle is adjusted, the support walls 139 and hinge walls 1310 are pressed together by screwing the clamping nut 135 on the hinge shaft 132 to ensure that the sample support stage 133 does not wobble. At the same time, a tilt angle scale 136 is provided around the hinge shaft 132 on the outer side of the hinge wall 1310, and a tilt angle pointer 137 pointing to the tilt angle scale 136 is provided vertically on the outer side of the support wall 139, so that the operator can accurately adjust the tilt angle of the sample support stage 133. Meanwhile, the top of the experimental platform 12 has several connecting screw holes 123, and the base 131 has connecting holes 138. The base 131 can be connected to any connecting screw hole 123 by bolts passing through the connecting holes 138, thereby fixing the stage 13 to the experimental platform 12. At the same time, the top of the sample support stage 133 has several mounting screw holes 134, which can be used to fix the container containing the sample to the top of the sample support stage 133 by bolt connection.

[0037] The experimental chamber 11 is also equipped with a humidity control device, and an ultraviolet lamp 32 facing the experimental table 12 is installed inside the experimental chamber 11. Both the humidity control device and the ultraviolet lamp 32 are connected to the power supply and the human-machine interface 5. The humidity control device is used to regulate the ambient humidity to increase the regulatory properties of humidity conditions, such as the corresponding phenomena of plants under high ambient humidity. The irradiation lamp 31 can simulate light environments of different intensities. In the entire electromagnetic spectrum, infrared rays and longer wavelengths can only produce simple thermal effects, while X-rays and gamma rays directly destroy most bioactive molecules. Only ultraviolet radiation can cause many active molecules to produce significant ionization or isomerization, while the destructive force is not too strong, thus producing special and diverse biological effects. However, this wavelength is strongly shielded by the ozone layer during the process of sunlight reaching the earth's surface. Therefore, in addition to the conventional irradiation lamp 31, this device is equipped with an ultraviolet lamp 32 to create an environment with strong ultraviolet radiation. In this embodiment, the ultraviolet lamp 32 is a dual-wavelength mercury lamp with wavelengths of 254nm and 365nm. The operator controls the humidity adjustment device and the intensity of the ultraviolet lamp 32 through the human-machine interface 5.

[0038] In this embodiment, the emitting ends of the irradiation lamp 31, ultraviolet lamp 32, and sound wave generator 2 are all mounted on the inner wall of the experimental chamber 11 via a rocker arm. The operator can control the rocker arm through the human-machine interface 5 to adjust the direction of the emitting ends of the irradiation lamp 31, ultraviolet lamp 32, and sound wave generator 2 to align them with the sample.

[0039] based on Figure 2 As shown, the humidity control device can be a common humidity regulator 93 with humidification and dehumidification functions. Both the humidification port and dehumidification port of the humidity regulator 93 extend into the experimental chamber 11. Solenoid valves controlled by the human-machine interface 5 are installed at the humidification port and dehumidification port to achieve on / off sealing control. Alternatively, based on... Figure 5 As shown, the humidity control device may also include a spray pipe 91 installed on the top side inside the experimental chamber 11, with atomizing nozzles 92 facing downwards. The spray pipe 91 is connected to a water tank or other water body via an external water pump. The water pump is controlled by the operator on the human-machine interface 5. The atomizing nozzles 92 can spray water into the experimental chamber 11 to simulate a high humidity environment and can operate normally under high or low pressure, but this method can only increase humidity. Correspondingly, a humidity sensor connected to the human-machine interface 5 is installed inside the experimental chamber 11 so that the operator can view the ambient humidity inside the experimental chamber 11 on the human-machine interface 5. The humidity sensor is installed on the inner wall of the experimental chamber 11.

[0040] Furthermore, based on Figure 2As shown, optionally, the electromagnetic field generator includes four sets of electromagnetic field units 61. Each set of electromagnetic field units 61 has an electromagnetic coil 611 and an electrode plate 612. Two sets of electromagnetic field units 61 are horizontal electromagnetic field units 61, and the other two sets are vertical electromagnetic field units 61. The two sets of horizontal electromagnetic field units 61 are located on both sides of the horizontal position of the sample space 14 and are arranged opposite to each other. The two sets of vertical electromagnetic field units 61 are located on the upper and lower sides of the sample space 14 and are arranged opposite to each other. In this way, electromagnetic field units 61 are arranged on both the horizontal and upper / lower sides of the sample space 14. The electromagnetic coils 611 of the two sets of horizontal electromagnetic field units 61 can generate a horizontal magnetic field in the sample space 14, and the electrode plates 612 of the two sets of horizontal electromagnetic field units 61 can generate a horizontal electric field in the sample space 14. The electromagnetic coils 611 of the two sets of vertical electromagnetic field units 61 can generate a vertical magnetic field at the sample space 14, and the electrode plates 612 of the two sets of vertical electromagnetic field units 61 can generate a vertical electric field at the sample space 14. With this setting, the magnetic field and electric field can be set to the horizontal and vertical directions, respectively, so as to realize the test and study of the different response phenomena of the sample when subjected to two electric or magnetic fields in two different directions under gravity.

[0041] based on Figure 2 As shown, to reserve space for installing the vertical electromagnetic field unit 61 located at the bottom of the sample space 14, a perforated bracket 121 is installed on the bottom wall of the experimental chamber 11. The top of the perforated bracket 121 has a turntable 122. The experimental chamber 12 is fixedly connected to the turntable 122. The vertical electromagnetic field unit 61 located at the bottom of the sample space 14 is disposed inside the perforated bracket 121 and installed on the bottom wall of the experimental chamber 11. The vertical electromagnetic field unit 61 located at the bottom of the sample space 14 is installed on the top wall of the experimental chamber 11. Meanwhile, based on... Figure 4 As shown, in order to more accurately adjust the rotation angle of the experimental platform 12, the top wall of the hollow support 121 is provided with a rotation scale 124 surrounding the experimental platform 12, and the edge of the experimental platform 12 is provided with a rotation pointer 125 pointing to the rotation scale 124.

[0042] In this embodiment, to prevent the hollow support 121, turntable 122, experimental stage 12, and sample stage 13 from affecting the electric and magnetic fields, all components on the hollow support 121, turntable 122, experimental stage 12, and sample stage 13 are made of non-magnetic insulating materials, such as PEEK. The bolts used to connect the experimental stage 12 and the base 131, as well as the bolts used to connect the sample container and the sample support stage 133, are also made of PEEK.

[0043] Furthermore, based on Figure 2 and Figure 6As shown, in each electromagnetic field unit 61, a non-magnetically insulating plate 613 is fixed to the end of the electromagnetic coil 611 facing the sample support stage 133. A slot 614 is provided on the non-magnetically insulating plate 613, and the end of the slot 614 has a contact terminal 615 connected to the power supply and human-machine interface 5. The electrode plate 612 can be detachably inserted into the slot 614 and electrically connected to the contact terminal 615. In actual experiments, electric and magnetic field environments will not occur simultaneously. In environments requiring a magnetic field, to avoid the electrode plate 612 affecting the magnetic field, it can be removed from the slot 614. The non-magnetically insulating plate 613 is also made of PEEK material and will not affect the distribution of the magnetic field. In environments requiring an electric field, the electrode plate 612 is inserted into the slot 614 and a voltage is applied through the contact terminal 615. The non-magnetically insulating plate 613 can prevent the electrode plate 612 from being mutually conductively affected by the iron core of the electromagnetic coil 611.

[0044] Meanwhile, to facilitate the wiring and installation of the electrode plate 612 and the electromagnetic coil 611, a mounting plate 620 is fixedly connected to the end of the electromagnetic coil 611 away from the non-magnetically insulating panel 613. The mounting plate 620 and the non-magnetically insulating panel 613 are connected to each other through a side plate 619 located to the side of the electromagnetic coil 611. Both the mounting plate 620 and the side plate 619 are made of PEEK material. The wiring led out from the contact terminal 615 passes through the interior of the non-magnetically insulating panel 613, the side plate 619, and the mounting plate 620 in sequence, and is led out to the side wall of the experimental chamber 11 and connected to the human-machine interface 5. The wiring of the electromagnetic coil 611 is led out from the interior of the mounting plate 620 to the side wall of the experimental chamber 11 and connected to the human-machine interface 5.

[0045] Furthermore, both sets of horizontal electromagnetic field units 61 are horizontally slidably disposed within the experimental chamber 11. These units can be moved closer to or further away from the sample space 14, allowing for adjustment of their distance from each other. For samples occupying less space, the two sets of electromagnetic field units 61 can be brought closer together to save power required for the same electric or magnetic field strength. The magnitudes of the magnetic and electric fields can be adjusted using current and voltage.

[0046] Specifically, in this embodiment, based on Figure 2As shown, telescopic devices are installed on both horizontal side walls of the experimental chamber 11. Each telescopic device includes a fixed sleeve 616 and a sliding sleeve 617. One end of the fixed sleeve 616 is fixedly installed on the side wall of the experimental chamber 11, and the sliding sleeve 617 is slidably fitted onto the end of the fixed sleeve 616 away from the side wall of the experimental chamber 11. The horizontal electromagnetic field unit 61 is fixedly connected to the end of the sliding sleeve 617 away from the fixed sleeve 616. A telescopic scale 618 is provided along the extension direction of the sliding sleeve 617. By sliding the sliding sleeve 617 along the fixed sleeve 616, the horizontal position of the horizontal electromagnetic field unit 61 can be adjusted. The telescopic scale 618 enables quantitative adjustment of the position.

[0047] In other embodiments, the horizontal position of the horizontal electromagnetic field unit 61 can also be adjusted in another way, based on Figure 5 As shown, the bottom wall of the experimental chamber 11 is provided with two sets of slide rails 111 located on both sides of the experimental platform 12. Both sets of slide rails 111 extend away from the experimental platform 12 and are located on the same straight line. Sliding seats 112 are fixedly installed at the bottom of each of the two sets of horizontal electromagnetic field units 61, specifically, the top of the sliding seat 112 is connected to the side plate 619. The two sets of horizontal electromagnetic field units 61 are slidably mounted on the two sets of slide rails 111 via corresponding sliding seats 112. The distance between the two sets of horizontal electromagnetic field units 61 can be adjusted by adjusting the position of the sliding seats 112 along the slide rails 111. The sliding of the sliding seats 112 along the slide rails 111 can be achieved by manual pushing, or by installing a horizontal electric push rod connected to the human-machine interface 5, which pushes and pulls the sliding seats 112.

[0048] Similarly, the two sets of vertical electromagnetic field units 61 can also be designed to be lifting-type to adjust the spacing between them. Lifting can be achieved by a vertical electric actuator or by a manually adjustable lifting bracket.

[0049] Furthermore, based on Figure 2As shown, the cabinet 1 also includes an equipment compartment 15, and the temperature control device includes an outdoor air conditioner unit 71 and an indoor air conditioner unit. The temperature control device is a commonly used device in test chambers for regulating temperature; its principle is the same as that of an air conditioner, capable of both cooling and heating. These are existing technologies, and their specific principles will not be elaborated further. The outdoor air conditioner unit 71 is located in the equipment compartment 15, with its heat dissipation end extending out of the cabinet 1. Specifically, the compressor, condenser, cooling fan, and four-way valve for switching between cooling and heating in the outdoor air conditioner unit 71 are located in the equipment compartment 15. The condenser connects to the cooling fan extending out of the cabinet 1 to achieve heat exchange with the environment. The indoor air conditioner unit includes an evaporator pipe 72, which is connected to the outdoor air conditioner unit 71 via a pressure reducing valve. The evaporator pipe 72 is distributed in a serpentine pattern along the inner wall of the test chamber 11 to ensure the uniformity of the internal temperature. The side walls of the test chamber 11 have a heat insulation layer 16. The insulation layer 16 can be a vacuum insulation layer 16 or filled with insulation material, which is an existing technology, to reduce the heat exchange between the interior of the experimental chamber 11 and the evaporator pipe 72 and the environment, and improve thermal efficiency.

[0050] In this embodiment, when the ambient temperature inside experimental chamber 11 is low, water droplets may condense on the inner wall of experimental chamber 11 and flow down the wall, collecting at the bottom. Therefore, drainage channels 113 are provided around the bottom wall of experimental chamber 11 to collect the condensed water. Drain valves can be provided on the side walls of experimental chamber 11 to drain the water from the drainage channels 113. Meanwhile, for some extremely high-temperature environments, heat exchange with refrigerant may be difficult to achieve. Therefore, an electric heating plate 114 can be installed on the inner side wall of the experimental chamber, connected to a power supply and a human-machine interface 5. Operators can heat the environment inside experimental chamber 11 using the electric heating plate 114.

[0051] based on Figure 2 and Figure 7As shown, the air pressure pump 4 is also located in the equipment compartment 15, and its port is connected to the experimental compartment 11. For the humidity control device, a humidity regulator 93 is used, and the main unit of the humidity regulator 93 is also located inside the equipment compartment 15. In this embodiment, the air pressure pump 4 has an air inlet 45 and an air outlet 45. Specifically, it also includes a three-way valve 41, a three-way valve 42, a vacuum valve 43, and a vacuum valve 44, all connected to the human-machine interface 5 via signals. The first port of the three-way valve 41 is connected to the air outlet 45, the second port of the three-way valve 41 is connected to the experimental compartment 11 via the vacuum valve 43, and the third port of the three-way valve 41 extends outside the equipment compartment and is connected to the atmospheric environment. The first port of the three-way valve 42 is connected to the experimental compartment 11 via the vacuum valve 44, the second port of the three-way valve 42 is connected to the air inlet 45, and the third port of the three-way valve 42 extends outside the equipment compartment and is connected to the atmospheric environment. When the pressure inside experimental chamber 11 needs to be increased, vacuum valve 43 opens, vacuum valve 44 closes, the port of three-way valve 41 connected to the environment is blocked, and the other two ports of three-way valve 41 open. The port of three-way valve 42 connected to vacuum valve 44 is blocked, and the other two ports of three-way valve 42 open. The air pump 4 is started, and ambient air is injected into experimental chamber 11 sequentially through three-way valve 42, inlet 45, outlet 45, three-way valve 41, and vacuum valve 43, increasing the pressure inside experimental chamber 11. When the pressure inside experimental chamber 11 needs to be decreased, vacuum valve 43 closes, vacuum valve 44 opens, the port of three-way valve 41 connected to vacuum valve 43 is blocked, and the other two ports of three-way valve 41 open. The port of three-way valve 42 connected to the environment is blocked, and the other two ports of three-way valve 42 open. When the air pump 4 is started, the gas in the experimental chamber 11 is discharged to the outside atmosphere through the vacuum valve 2 44, the three-way valve 2 42, the air inlet 45, the air outlet 45 and the three-way valve 1 41 in sequence, and the pressure in the experimental chamber 11 decreases.

[0052] In other embodiments, the air pressure pump 4 may be a vacuum pump that can both pressurize and evacuate, so that the pressure inside the experimental chamber 11 is higher or lower than atmospheric pressure.

[0053] The specific usage of the multi-environment coupling experimental cabinet in this embodiment is as follows: Before the experiment, depending on the required experimental environment, the sample support stage 133 is fixed to a specific position on the experimental stage 12 with bolts, and the container containing the sample is fixed to the sample support stage 133 with bolts. For terrestrial plants, they can be planted in experimental pots containing soil, with the experimental pot serving as the container. For terrestrial organisms, the organisms can be placed in experimental cages, with the experimental cage serving as the container. For microorganisms, they can be placed on glass slides, with clamps on the sample stage to clamp and fix the glass slides, with the clamps serving as the container.

[0054] Subsequently, the position of the sliding sleeve 617 is manually adjusted to determine the horizontal distance between the two sets of horizontal electromagnetic field units 61. The orientation of the experimental platform 12 is adjusted by manually rotating the turntable, and the tilt angle of the sample is adjusted by manually adjusting the pitch angle of the sample support platform 133. If an electric field needs to be applied in the experimental environment, the electrode plate 612 is inserted into the slot 614; otherwise, the electrode plate 612 is removed from the experimental chamber 11. After adjustment, the sealed chamber door is closed and locked.

[0055] Depending on the required environment for testing, the operator adjusts the necessary environmental parameters via the human-machine interface 5. For example, to study the effects of a terrestrial plant on a 5000V / m horizontal electric field under gravity conditions at a 20-degree angle to the horizontal, a low-pressure environment of 0.5 atmospheres, a high-temperature environment of 50 degrees Celsius, and a 10Hz infrasound environment for a duration of 3 hours, the angle of the sample support platform can be adjusted to a 20-degree tilt angle. The pressure in the experimental chamber 11 can be adjusted to the set value using the air pump 4, the temperature control device can be set to the set value, the sound generator 2 can apply a 10Hz infrasound wave to the sample, the irradiation lamp 31 can simulate a solar environment, and the electrode plates 612 in the two sets of horizontal electromagnetic field units 61 can apply a set value of horizontal electric field at the sample space 14 for a continuous 3-hour experiment.

[0056] For example, to study the changes in microorganisms under an ambient temperature of 25 degrees Celsius and an atmosphere of one atmosphere when subjected to a 20mT vertical magnetic field and ultraviolet irradiation for one hour, a temperature control device can be used to adjust the ambient temperature to 25 degrees Celsius. A vertical magnetic field of a set intensity is applied to the sample through the electromagnetic coils 611 in the two sets of vertical electromagnetic field units 61, and the sample is irradiated by an ultraviolet lamp 32. The entire process lasts for one hour.

[0057] For example, to study the working state of an electronic device under an ambient temperature of 40 degrees Celsius and a pressure of two atmospheres, and subjected to a horizontal electric field of 300V / m for 5 hours, the pressure of the experimental chamber 11 is adjusted to the set value by the air pressure pump 4, the ambient temperature is adjusted to the set value by the temperature control device, and the electrode plates 612 in the two sets of horizontal electromagnetic field units 61 apply the set value of horizontal electric field at the sample space 14 for 5 hours.

[0058] During the experiment, the operator can observe the parameters in real time through the human-machine interface 5 and observe the sample's reaction in real time through the images captured by the camera 10. After the experiment, the temperature and pressure in the experimental chamber 11 are restored to the ambient temperature and pressure. The electromagnetic field generator, sound wave generator 2, irradiation lamp 31, ultraviolet lamp 32 and driving device are turned off. The sealed chamber door is opened, and the operator takes out the sample to detect changes in the sample or to conduct further molecular or genetic studies on the biological sample.

[0059] This application's multi-environment coupling experimental cabinet can simulate inclined or horizontal gravity environments through an adjustable tilt and orientation sample support stage 133; simulate horizontal or vertical electric and magnetic field environments through an electromagnetic field generator; simulate different temperature environments through a temperature control device; simulate infrasound, audible sound, and ultrasonic environments through a sound wave generator 2; simulate sunlight and ultraviolet irradiation environments through irradiation lamps 31 and 32; simulate different pressure environments through a pressure pump 4; and simulate high humidity environments through a humidity control device. These experimental environments can be adjusted individually and coupled together to achieve multi-environment coupling, thereby detecting the response phenomena of samples under complex coupled environments. Compared to existing methods of testing different environments separately, this reduces the number of experimental devices and allows observation of the comprehensive effects produced by samples under multiple coupled conditions. This multi-environment coupling experimental cabinet can be used for the detection of terrestrial organisms, aquatic organisms, and microorganisms, as well as for the response phenomena of non-biological samples, such as certain substances, under different environments.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
