Description

Technical Field

[0001] This utility model belongs to the field of forestry and plant ecology technology, and specifically relates to an open-top box for simulating heat stress. Background Technology

[0002] Global warming has led to a sustained rise in average temperatures, significantly increasing the risk of plants suffering from heat stress. Furthermore, a warming and drying climate may increase the frequency and intensity of extreme weather events, such as heat waves. These extreme events cause severe heat stress to plants, affecting physiological processes such as photosynthesis, respiration, and transpiration, leading to physiological disorders, growth stunts, and even death. High-temperature heat stress disrupts normal plant metabolism, growth, development, and productivity, posing a significant threat to the stability of forest ecosystems. Plant adaptation to heat stress refers to the morphological, physiological, biochemical, and molecular-level adjustments and regulation processes initiated by plants when environmental temperatures exceed their optimal range during growth. Understanding the mechanisms of plant adaptation to heat stress is crucial for accurately predicting plant responses to global climate change and is of great significance for the conservation of plant resources and the maintenance of ecosystem stability. Analyzing the changes in plant physiological processes under simulated heat stress conditions is an essential approach to studying plant adaptation mechanisms to heat stress.

[0003] Existing heat stress simulation technologies lack outdoor simulation capabilities, limiting current heat stress simulations of plants to small seedlings in laboratory incubators, failing to fully simulate the in-situ growth environment of plants outdoors. While outdoor open-top chambers offer the option, current technology lacks automatic control over the opening size, hindering flexible temperature control and failing to meet the required simulation temperature range. Furthermore, high-temperature heat stress can be further categorized into humid and dry heat types, and conventional heat stress simulation devices neglect humidity control, limiting the application scenarios for heat stress simulation and research. To address these shortcomings, this invention designs an open-top heat stress simulation chamber. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, this utility model, by setting a rotating ring, when it is necessary to control the internal temperature of FRP polycarbonate sheet one, firstly, when the air temperature sensor detects that the internal temperature of FRP polycarbonate sheet one is too low, the motor drives the lead screw to rotate in the opposite direction, controlling the threaded slider to move closer to the motor. The moving threaded slider uses the connecting rod to push the connecting strip, causing the connecting block, connecting plate and rotating ring to rotate.

If the air temperature sensor detects that the internal temperature of FRP polycarbonate sheet one is too high, the motor needs to drive the lead screw to flip, thereby controlling the rotating ring and connecting ring one to rotate in the opposite direction, opening the tightening of FRP polycarbonate sheet two, increasing the amount of external air entering FRP polycarbonate sheet one to lower the temperature. This device facilitates the control of the internal temperature of FRP polycarbonate sheet one. Attached Figure Description

[0027] Further explanation is needed: the FRP sun panel 1 is supported by the support frame 101 and the circular frame 102 to facilitate covering the plants. A closing mechanism 3 and a transmission mechanism 4 are installed on the top of the FRP sun panel 1 via a fixing ring 2. The transmission mechanism 4 controls the size of the opening of the FRP sun panel 301 to facilitate the control of the internal temperature of the FRP sun panel 1.

[0028] Example 2

[0029] Please see Figure 2-5 The present invention provides the following technical solution:

[0030] The transmission mechanism 4 includes a rotating ring 401, a connecting plate 402, a connecting block 403, a connecting strip 404, a motor 405, a lead screw 406, a threaded slider 407, a connecting rod 408, and an air temperature sensor 409. The rotating ring 401 is located at the top of the FRP polycarbonate sheet 1. The bottom of the rotating ring 401 is fixedly connected to the connecting plate 402. The lower surface of the connecting plate 402 is fixedly connected to the connecting block 403. The connecting strip 404 is fixedly connected to one side of the connecting block 403. The motor 405 is located at the top of the FRP polycarbonate sheet 1. The lead screw 406 is located on one side of the motor 405. The outer surface of the lead screw 406 is threaded with the threaded slider 407. The upper surface of the threaded slider 407 is fixedly connected to the connecting rod 408. The air temperature sensor 409 is located inside the FRP polycarbonate sheet 1.

[0031] An annular groove 201 is provided on the upper surface of the fixing ring 2, and a limiting groove 202 is provided on one side of the fixing ring 2.

[0032] The closing mechanism 3 includes an FRP polycarbonate sheet 2 301, a connecting ring 1 302, a connecting ring 2 303, and a slot 304. The FRP polycarbonate sheet 2 301 is located on top of the FRP polycarbonate sheet 1. The connecting ring 1 302 is fixedly connected to one side of the rotating ring 401. The connecting ring 2 303 is fixedly connected to one side of the fixed ring 2. A slot 304 is provided on one side of the connecting ring 1 302.

[0033] The swivel ring 401 is rotatably connected to the top of the fixed ring 2, and the connecting plate 402 is rotatably connected to the top of the fixed ring 2.

[0034] The connecting block 403 is rotatably connected inside the annular groove 201, and the connecting strip 404 is rotatably connected inside the limiting groove 202.

[0035] The threaded slider 407 is slidably connected to the top of the FRP sun sheet 1, the connecting rod 408 is set inside the connecting strip 404, and the air temperature sensor 409 is fixedly installed inside the support frame 101.

[0036] FRP sun sheet 2 301 is fixedly connected inside the connecting ring 1 302, and FRP sun sheet 2 301 is fixedly connected inside the slot 304.

[0037] Further explanation is needed: The FRP polycarbonate sheet 1 also contains an intelligent temperature controller, an air humidity sensor, an intelligent humidity controller, a humidifier, a dehumidifier, and an air circulator. The air temperature sensor 409 is a VP3 air temperature sensor. Firstly, when the air temperature sensor 409 detects that the temperature inside the FRP polycarbonate sheet 1 is too low, the motor 405 drives the lead screw 406 to rotate in the opposite direction, controlling the threaded slider 407 to move closer to the motor 405. The moving threaded slider 407 uses the connecting rod 408 to move the connecting bar 404, which in turn drives the connecting block 403 and the connecting plate. 402 and the rotating ring 401 rotate. At this time, the rotating ring 401 and the connecting ring 302 drive the top of the FRP sun panel 301 to rotate one revolution, slowly twisting the center of the FRP sun panel 301 to control the loss of temperature inside the FRP sun panel 301. If the air temperature sensor 409 detects that the temperature inside the FRP sun panel 301 is too high, the motor 405 needs to drive the lead screw 406 to flip, thereby controlling the rotating ring 401 and the connecting ring 302 to rotate in the opposite direction to open the opening of the FRP sun panel 301, increasing the amount of external air entering the FRP sun panel 301 to reduce the temperature.

[0038] Working principle: When a heat stress simulation open-top box is used, the FRP sun panel 1 is first supported by the support frame 101 and the circular frame 102 to facilitate covering the plants. A closing mechanism 3 and a transmission mechanism 4 are installed on the top of the FRP sun panel 1 through the fixing ring 2. The size of the opening of the FRP sun panel 301 is controlled by the transmission mechanism 4 to facilitate the control of the internal temperature of the FRP sun panel 1.

[0039] When it is necessary to control the internal temperature of FRP polycarbonate sheet 1, the air temperature sensor 409 first detects that the internal temperature of FRP polycarbonate sheet 1 is too low. Then, the motor 405 drives the lead screw 406 to rotate in the opposite direction, controlling the threaded slider 407 to move closer to the motor 405. The moving threaded slider 407 uses the connecting rod 408 to actuate the connecting bar 404, causing the connecting block 403, connecting plate 402, and rotating ring 401 to rotate. At this time, the rotating ring 401 and connecting ring 302 cause the top of FRP polycarbonate sheet 301 to rotate. One rotation slowly tightens the center of FRP sun panel 2 301 to control the loss of temperature inside FRP sun panel 1. If the air temperature sensor 409 detects that the temperature inside FRP sun panel 1 is too high, the motor 405 drives the lead screw 406 to rotate, thereby controlling the rotating ring 401 and connecting ring 1 302 to rotate in the opposite direction to open the tightening of FRP sun panel 2 301, increasing the amount of external air entering FRP sun panel 1 to lower the temperature. This device facilitates the control of the temperature inside FRP sun panel 1.

[0040] When the air humidity sensor detects high humidity inside the FRP polycarbonate panel, the intelligent humidity controller activates a dehumidifier to lower the humidity. Conversely, when the humidity is low, the intelligent humidity controller activates a humidifier to increase the humidity. This device facilitates automatic control of the temperature and humidity inside the FRP polycarbonate panel, simulating hot and dry conditions and humid environments. It can be used to study the thermal stress response characteristics and adaptation mechanisms of plants under global change.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
