Description

TECHNICAL FIELD

[0001] The present application relates to the field of climate chamber technology, and in particular to an energy-saving artificial climate chamber installed in a room that can be sterilized and disinfected. BACKGROUND

[0002] An artificial climate chamber is an experimental device that can simulate meteorological conditions in nature indoors, and can be effectively regulated according to different needs. It mainly automatically controls and adjusts various environmental factors such as temperature, humidity, and light in a specific small environment to meet the needs of a specific plant growing environment. Because it is not limited by geographical and seasonal natural conditions and can shorten the research period, it has become an important device for scientific research and production. An artificial climate chamber is composed of a control panel, an air treatment room, and a plant growing room. The control panel indicates the set values of various environmental factors, compares the values collected by the sensors, feeds back the control and regulation device, and thus achieves the purpose of controlling the indoor environment.

[0003] China's artificial climate chamber started relatively late, built by the Institute of Botany, Chinese Academy of Sciences in 1969, but the development speed is relatively fast, and the artificial climate chamber is mainly divided into sunlight type artificial climate chamber, high-illumination artificial climate chamber and culture shelf artificial climate chamber, the sunlight type artificial climate chamber mainly relies on sunlight, and is supplemented by artificial light; although the Chinese patent "artificial climate chamber" (patent number: CN106288210A) has made certain improvements in technology, and added the cooling, heating and light supplementing device of the sunlight room, but because the main material of the library body is still glass, the heat preservation performance is poor, so the temperature control is relatively weak, and the low temperature and high temperature stress test of plants cannot be carried out; although the Chinese patent "a sunlight type artificial climate chamber with double-layer structure" (patent number: CN104067885B) proposes a double-layer structure containing an air treatment room, but because the air treatment room is located at the lower part of the indoor room of the artificial climate chamber, there is a certain requirement for the overall height of the artificial climate chamber, otherwise the height of the indoor room of the artificial climate chamber will be affected, and it cannot be well installed and applied in the room. When the limit temperature of the plant culture is controlled, the heat dissipation and cold dissipation of the library board of the high-illumination artificial climate chamber and the culture shelf artificial climate chamber are relatively rapid, which leads to low energy utilization rate of the artificial climate chamber and waste of too much electric power resource. Although the Chinese patent "indoor type plant growth artificial climate chamber fully utilizing sunlight" (patent number: CN102293132A) adopts polyurethane sandwich plate color steel plate as the library body, but because it fully utilizes sunlight as the plant growth energy, artificial light supplementing cannot be adopted in the season of continuous rain or in the city with poor applicability. Because the existing artificial climate chamber is used for cultivating plants for a long time, and is relatively airtight, indoor bacteria and insect pests are easy to harm plants, therefore, how to solve the problems of sterilization and disinfection of the artificial climate chamber, high energy consumption and narrow temperature control range is a problem to be solved by the technical personnel at present.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] As attached Figure 1 To be continued Figure 4 As shown:

[0034] Example 1:

[0035] This invention provides an energy-saving artificial climate chamber that can be installed indoors and sterilizes and disinfects. It includes a chamber body, which is a hexahedral structure and is composed of rigid polyurethane sandwich panel units with metal surfaces. The joints are sealed with engineering adhesive. The chamber body is horizontally divided into a larger plant growth chamber 1 and a smaller air handling chamber 2.

[0036] One side of the air handling room 2 is equipped with a maintenance window made of one-piece rigid polyurethane sandwich panel with a metal surface. The maintenance window is equipped with a sealing strip and an emergency door lock around its perimeter.

[0037] The air handling chamber 2 is equipped with a condenser 4 on the outside and an evaporator 5, a humidifier 11, and a dehumidifier 12 inside. A fresh air unit 7 is connected to the top, and a control box 10 is installed at the front end. The control box 10 has a built-in programmable logic controller (PLC).

[0038] The plant growth chamber 1 has air ducts 6 on both sides of the top, air outlets are evenly distributed on the sides of the air ducts 6, and return air inlets 8 are provided in the middle and lower part. Sensors 9 are installed near the return air inlets 8. A control panel 3, an ozone generator 14 and a mist sprayer 15 are installed on the side of the door of the plant growth chamber 1.

[0039] The air inlet of the air duct 6 is connected to the air handling chamber 2, and the air outlet of the air duct 6 is combined with the return air outlet 8 to form an air circulation, so that the temperature difference in all parts of the plant growth chamber 1 does not exceed 1℃.

[0040] The plant growth chamber 1 has an observation window 16 near the door on the front side. The observation window 16 has a built-in temperature control system that is linked with the sensing element 9. When the temperature difference between the indoor and outdoor temperatures is ≥10℃, it will automatically turn on the power to defog.

[0041] The mist sprayer 15 is equipped with an independent power supply, has an anti-corrosion coating on its body, is electrically connected to the control box 10, and can be started via the control panel 3. It is used in conjunction with insecticides or fungicides for pest control.

[0042] Several short-wave ultraviolet lamps 13 are installed on the top of the plant growth chamber 1, and the short-wave ultraviolet lamps 13 are electrically connected to the control box 10;

[0043] Control panel 3, evaporator 5, humidifier 11, dehumidifier 12, fresh air unit 7, sensor element 9, ozone generator 14, and mist sprayer 15 are all electrically connected to the PLC of control box 10.

[0044] Several full-spectrum incubator lamps 24 are arranged on the bottom surface of the support frame 17 near the two adjacent short-wave ultraviolet lamps 13. The control panel 3 also integrates a "full-spectrum illumination setting" module, which can control the start and stop and output power of the full-spectrum incubator lamps 24 according to the set value.

[0045] The full-spectrum cultivation lamp 24 and the short-wave ultraviolet lamp 13 are independently controlled and can be turned on or off separately to avoid damage to plants caused by ultraviolet rays during the sterilization process.

[0046] The plant growth chamber 1 is also equipped with a lifting mechanism at the top to adjust the height of the short-wave ultraviolet lamp 13.

[0047] Working Principle: First, the staff assembles the device. Based on the indoor space dimensions, the unit is constructed using rigid polyurethane sandwich panels with metal surfaces, horizontally dividing the larger plant growth chamber 1 into a smaller air handling chamber 2. The joints are filled with engineering adhesive and compacted to ensure a leak-proof seal. The condenser 4 is fixed to a designated position outside the air handling chamber 2. The evaporator 5, humidifier 11, and dehumidifier 12 are confirmed to be securely installed inside the air handling chamber 2 and accurately connected to the PLC. The fresh air unit 7 is connected to the top interface of the air handling chamber 2. The air inlet of the duct 6 is sealed to the side outlet of the air handling chamber 2. The outlets are distributed on both sides of the top of the plant growth chamber 1, and the return air inlet 8 is aligned with the connection between the two chambers. Then, the lifting mechanism components are assembled: First, the fixing plate 19 is fixed to the top of the plant growth chamber 1. Fixing hooks 20 are installed on both sides of the bottom of the fixing plate 19, and the winding frame 22 and drive unit 23 are assembled in the middle of the top. Then... Several short-wave ultraviolet lamps 13 are evenly installed on the upper surface of the support frame 17. At the same time, the full-spectrum cultivation lamp 24 is fixed to the bottom surface of the support frame 17 by clips and is located between two adjacent short-wave ultraviolet lamps 13 (ensuring that the light does not overlap or block the light). The wires of the short-wave ultraviolet lamps 13 and the full-spectrum cultivation lamp 24 are gathered to the junction box at the top of the support frame 17, and then connected to the control box 10 through the fixing hole 21 of the fixing plate 19 via flexible conduit to avoid wear or tangling of the wires during subsequent lifting. Finally, the pull ropes 18 at the four corners of the support frame 17 are passed through the through holes of the fixing hooks 20 and wound around the rotating shaft of the winding frame 22. The tension of the pull ropes 18 is adjusted to ensure that the support frame 17 is suspended stably. At the same time, it is confirmed that the emergency door lock on the inside of the plant growth chamber 1 can be released normally and that the maintenance window sealing strip is not damaged. The plants to be cultivated (such as crop seedlings) are placed on the cultivation rack, the sliding door is closed, and the rubber sealing strip around the door is used to ensure a tight seal.

[0048] Next, the staff started the device, connected the power supply to the control box 10, and entered the parameter setting interface by entering the operation password through the control panel 3; set the temperature and humidity according to the plant cultivation requirements (e.g., 25℃ and 65% for normal temperature seedling cultivation), and set the parameters through the "full spectrum light setting" module: light cycle 12 hours, intensity 8000 lux, and check the "independent control" function (to ensure that it does not interfere with the start and stop of the short-wave ultraviolet lamp 13). After the parameters are stored by the PLC, the PLC sends a detection command to the sensing element 9, and the sensing element 9 collects the real-time temperature and humidity of the return air vent 8 and feeds it back to the PLC;

[0049] Subsequently, the PLC compares the set value with the actual value. If the temperature is too high or the humidity is too low, it sends a cooling command to the evaporator 5 and condenser 4, and a humidifying command to the humidifier 11. The fresh air unit 7 starts to draw outdoor air into the air handling chamber 2, mixes it with the treated air, and sends it into the plant growth chamber 1 through the air duct 6. Then, it returns through the return air vent 8 to form a circulation. The insulation effect of the rigid polyurethane sandwich panel with metal surface, combined with the air circulation, keeps the indoor temperature difference ≤1℃. When the light start time is reached, the PLC sends a start command to the full-spectrum cultivation lamp 24. The lamp emits full-spectrum light of 400-700nm. The sensing element 9 monitors the light intensity in real time. If it is lower than the set value, it feeds back to the PLC to fine-tune the lamp power. If the light height needs to be adjusted... To accommodate plant growth (e.g., seedlings reaching 1.2m in height), the operator inputs the target height of 1.3m into the control panel 3. The PLC-controlled drive unit 23 then operates, the winding frame 22 releases the pull rope 18, and the support frame 17, carrying the short-wave ultraviolet lamp 13 and the full-spectrum cultivation lamp 24, descends smoothly and synchronously. The through-hole of the fixing hook 20 guides the pull rope 18, preventing the support frame 17 from tilting. When the height sensor detects that the full-spectrum cultivation lamp 24 has reached 1.3m, the PLC-controlled drive unit 23 self-locks, fixing the lamp height to ensure light coverage of the top of the plant. The full-spectrum cultivation lamp 24 and the short-wave ultraviolet lamp 13 are controlled independently. If sterilization is required, only the short-wave ultraviolet lamp 13 is activated, while the full-spectrum cultivation lamp 24 remains off to prevent ultraviolet damage to the plant.

[0050] During long-term operation and maintenance, the short-wave ultraviolet lamp 13 is periodically activated via the control panel 3 for sterilization (set time 30 minutes), during which the full-spectrum incubation lamp 24 is locked and turned off. If pest control is required, the mist sprayer 15 is activated to spray the agent. When the indoor and outdoor temperature difference is ≥10℃, the observation window 16 automatically defogs. During maintenance, first disconnect the power and check the full-spectrum incubation lamp 24 under the support frame 17: wipe the dust off the lamp surface with a lint-free cloth, check whether the buckles are secure and whether the wires are worn. If the lamp is faulty, it can be replaced by disassembling the buckles. At the same time, check the coupling status of the pull rope 18 and the winding frame 22 to ensure smooth subsequent lifting and lowering.

[0051] Example 2:

[0052] This embodiment is basically the same as the previous embodiment, except that the lifting mechanism includes a support frame 17, which is movably set at the top of the plant growth chamber 1. Multiple short-wave ultraviolet lamps 13 are installed on the support frame 17. Pull ropes 18 are fixedly connected to the four corners of the upper surface of the support frame 17. A fixing plate 19 is fixedly installed at the top of the plant growth chamber 1. Fixing hooks 20 are symmetrically fixed to the two sides of the bottom end of the fixing plate 19. A fixing hole 21 is opened through the middle of the bottom end of the fixing plate 19. A winding frame 22 is set at the middle of the top end of the fixing plate 19. One end of the multiple pull ropes 18 is wound around the rotating shaft of the winding frame 22. A drive part 23 is set on one side of the rotating shaft of the winding frame 22. The drive part 23 is a self-locking servo motor.

[0053] The bottom of the fixed hook 20 is integrally formed with a through hole. One side of the outer surface of the pull rope 18 is located inside the through hole. Multiple pull ropes 18 are located inside the winding frame 22. The pull ropes 18 and the winding frame 22 are coupled to each other.

[0054] The control panel 3 integrates a "UV lamp height adjustment" module, which can input a height value of 0.5 to 2.0m. The PLC controls the drive unit 23 to operate according to the input value, driving the short-wave UV lamp 13 to rise and fall to the target height.

[0055] Working principle: First, the staff determines the target height of the lamps based on the current height of the plant. For example, when cultivating vegetable seedlings that are 0.8m tall, the full-spectrum cultivation lamp 24 and the short-wave ultraviolet lamp 13 need to be adjusted to 0.9m (slightly higher than the top of the plant to ensure unobstructed light). The parameter of 0.9m is input through the "Ultraviolet Lamp - Cultivation Lamp Synchronous Lifting and Lowering" module of the control panel 3 and transmitted to the PLC.

[0056] Next, the PLC sends a forward rotation command to the drive unit 23 (self-locking servo motor), and the drive unit 23 outputs torque to drive the winding frame 22 to rotate clockwise. Since the pull rope 18 is coupled with the winding frame 22, the pull rope 18 is gradually released, and its end away from the winding frame 22 is fixed to the four corners of the support frame 17. Under the action of gravity, the support frame 17 moves downward synchronously with the short-wave ultraviolet lamp 13 on the upper surface and the full-spectrum incubation lamp 24 on the lower surface. When the pull rope 18 moves, it passes through the through hole of the fixed hook 20. The fixed hook 20 guides the pull rope 18 to prevent the support frame 17 from tilting and ensure that the two types of lamps move smoothly vertically. At the same time, the wires in the junction box at the top of the support frame 17 pass through the fixed hole 21 of the fixed plate 19 through the flexible conduit and extend and retract synchronously with the movement of the support frame 17 to avoid the wires from getting tangled or worn.

[0057] Subsequently, the height sensor (electrically connected to the PLC) next to the fixed plate 19 detects the height of the full-spectrum incubator lamp 24 in real time (using its bottom as the detection reference). When the actual height reaches 0.9m, it immediately sends a signal to the PLC. The PLC sends a stop command, the drive unit 23 stops operating and activates the self-locking function to lock the position of the winding frame 22, preventing the pull rope 18 from loosening and causing the lamp to slip. At this time, both the short-wave ultraviolet lamp 13 and the full-spectrum incubator lamp 24 are stably at a height of 0.9m. The full-spectrum incubator lamp 24 can be started independently according to the setting (such as turning on the light cycle of 12 hours), while the short-wave ultraviolet lamp 13 remains off, and the two do not interfere with each other.

[0058] If the plants grow to 1.5m, the staff only needs to re-enter the target height of 1.6m on the control panel 3. The PLC control drive unit 23 reverses, the winding frame 22 winds up the pull rope 18, and pulls the support frame 17 and the two types of lamps to rise synchronously. When the height sensor detects that the full-spectrum cultivation lamp 24 has reached 1.6m, the PLC control drive unit 23 locks itself, completing the height adjustment. During the entire lifting process, the relative positions of the full-spectrum cultivation lamp 24 and the short-wave ultraviolet lamp 13 remain unchanged (always kept on the upper and lower sides of the support frame 17) to avoid light angle deviation. If sterilization is required, only the short-wave ultraviolet lamp 13 is activated, and the full-spectrum cultivation lamp 24 remains off. If supplemental lighting is required, only the full-spectrum cultivation lamp 24 is activated, and the short-wave ultraviolet lamp 13 is locked.

[0059] During maintenance, after powering off, check the support frame 17: confirm whether the buckles of the full-spectrum cultivation lamp 24 are secure and whether the wires are worn due to lifting and lowering. If the lamp needs to be replaced, simply remove the buckles. At the same time, check the tension of the pull rope 18 to ensure that it is tightly coupled with the winding frame 22 to avoid jamming during the next lifting and lowering. Through this design, the synchronous height adaptation of the two types of lamps can be achieved, which simplifies the operation and ensures that the light always meets the needs of plant growth.

[0060] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
