Abstract
Description
Technical Field
[0001] This application relates to the technical field of control cabinets, and in particular to a modular environmental control cabinet for a plant factory. Background Technology
[0002] Modular environmental control cabinets for plant factories are intelligent control devices designed specifically for plant factory environments. Based on a modular concept, they possess multiple functions. For ease of control, existing designs typically employ modularity, dividing the control cabinet into ventilation control modules, supplemental lighting control modules, sprinkler control modules, and central control modules. Each module is relatively independent yet works in tandem, facilitating installation, maintenance, and upgrades. They can be flexibly combined according to the scale and needs of the plant factory.
[0003] A search revealed Chinese patent application CN202222758555.5, which discloses an intelligent environmental controller that facilitates protection, improves work efficiency, and enhances practicality. The controller includes a main body and a protective assembly, with the main body mounted on the protective assembly. The protective assembly includes a protective shell, two sets of switch doors, side baffles, and two sets of T-blocks. A protective cavity is provided inside the protective shell, with an inlet / outlet penetrating through the front end of the cavity. The outer ends of the two sets of switch doors are hinged to the left and right ends of the inlet / outlet, respectively. The main body is installed inside the protective cavity. Ventilation holes are provided through the left and right ends of the protective cavity, and filter components are installed in each of the two ventilation holes. The two sets of baffles are fixedly installed on the left and right ends of the protective shell, respectively. T-slots are provided on the left and right sides of the front end of the protective cavity, and the two sets of T-blocks are slidably connected to the two sets of T-slots. Placement slots are provided on the top of each set of T-blocks, containing desiccants. A ventilation assembly is provided on the top of the protective cavity.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The existing technologies use micro fans to dissipate heat from the inside of the cabinet. However, in actual use, when the outdoor temperature is too high in summer, the temperature difference between the outside environment and the inside of the cabinet becomes smaller. According to the laws of heat transfer, the smaller the temperature difference, the weaker the heat transfer force and the slower the heat transfer speed. This makes it difficult for the heat inside the cabinet to be quickly and effectively dissipated to the outside environment, resulting in unsatisfactory heat dissipation. Utility Model Content

[0015] 1. This utility model, by setting up components such as adjustment ports, drive slots, linkage rods, and semiconductor cooling chips, enables the following: when the external air temperature is high and air cooling cannot achieve the corresponding heat dissipation effect, the temperature sensor can detect the high temperature and transmit the signal to the control module.

[0016] 2.

This causes the semiconductor cooling chip to flip, bringing the heat dissipation surface closer to the fan. This provides appropriate heating to the inside of the cabinet, preventing performance degradation of components in low-temperature environments and further ensuring the effectiveness of the modular control device under special conditions.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.
[0023] This application discloses a modular environmental control cabinet for a plant factory. For example... Figure 1-4As shown, the device includes a cabinet shell 1. A modular control device 2 is fixedly connected to one side of the inner wall of the cabinet shell 1. A sealing door 3 is rotatably fitted to the front side of the cabinet shell 1. Flow ports 22 are opened on both sides of the inner wall of the cabinet shell 1. An L-shaped air guide duct 4 is fixedly connected to one side of the inner wall of the two flow ports 22. A fan 5 is installed on the inner wall of the L-shaped air guide duct 4. An adjustment port 6 is opened on one side of the L-shaped air guide duct 4. A drive groove 7 is opened on the lower side of the inner wall of the adjustment port 6. A linkage rod 8 is rotatably fitted to the lower side of the inner wall of the drive groove 7. A semiconductor cooling chip 9 is fixedly connected to the upper end of the linkage rod 8. The semiconductor cooling chip 9 realizes the cooling or heating function based on the Peltier effect, which is the prior art. A cooling fan 10 is fixedly connected to one side of the semiconductor cooling chip 9.
[0024] Please see Figure 2 A protective net 16 is fixedly connected to the inner wall of the other of the two flow ports 22, and a dustproof net 17 is fixedly connected to the lower side of the inner wall of the L-shaped air duct 4. The protective net 16 can easily protect one of the flow ports 22, reducing the possibility of animals crawling into the cabinet shell 1 and causing damage. The dustproof net 17 can filter the flowing air.
[0025] Please see Figure 1 An alarm 18 is fixedly connected to the upper side of the cabinet shell 1. The alarm 18 and the control module 12 are electrically connected. When the temperature inside the cabinet shell 1 is too high and cannot be lowered, the control module 12 transmits the signal to the alarm 18 to trigger an alarm and remind personnel to handle the situation in a timely manner.
[0026] Please see Figure 2 A placement frame 19 is fixedly connected to the lower side of the inner wall of the cabinet shell 1. A moisture-absorbing block 20 is provided on the inner wall of the placement frame 19. By placing the moisture-absorbing block 20 inside the placement frame 19, the moisture-absorbing block 20 can absorb moisture from the inside of the cabinet shell 1, thereby improving the overall dryness of the interior.
[0027] Please see Figure 2 and Figure 4 A locking groove 14 is provided on one side of the inner wall of the cabinet shell 1, and a closing lock 15 is provided on the sealing door 3 to cooperate with the locking groove 14. The closing lock 15 and the locking groove 14 cooperate with each other. When the cabinet shell 1 is closed, the sealing door 3 can be fixed by the cooperation of the closing lock 15 and the locking groove 14.
[0028] A drive mechanism 11 is provided on the lower side of the inner wall of the drive slot 7. A control module 12 that cooperates with the drive mechanism 11 is fixedly connected to one side of the inner wall of the cabinet 1. A temperature sensor 13 that cooperates with the control module 12 is fixedly connected to the upper side of the inner wall of the cabinet 1.
[0029] Please see Figure 3The drive mechanism 11 includes a micro motor 111 fixedly connected to the lower side of the inner wall of the drive groove 7, a drive gear 112 fixedly connected to the output end of the micro motor 111, and a driven gear 113 fixedly connected to the linkage rod 8 and meshing with the drive gear 112.
[0030] Please see Figure 2 Both sides of the semiconductor cooling chip 9 are fixedly connected with heat-resistant rubber 21. The opposite end of the heat-resistant rubber 21 abuts against both sides of the inner wall of the adjustment port 6. When the semiconductor cooling chip 9 is rotated, the heat-resistant rubber 21 will fit against the inner wall of the adjustment port 6 for sealing. The heat-resistant rubber 21 not only has heat protection but also has a certain degree of flexibility.
[0031] The implementation principle of a modular environmental control cabinet for a plant factory in this application embodiment is as follows: When in use, the modular control device 2 inside the cabinet shell 1 is connected to the ventilation, supplemental lighting, and sprinkler systems in the plant engineering, and can be controlled by the corresponding modular control device 2. During use, the fan 5 is started and rotates inside the L-shaped air duct 4 to blow air into the inside of the cabinet shell 1, and the rest is discharged from another flow port 22 to achieve heat dissipation.
[0032] When the outside air temperature is high, and the air cooling cannot achieve the corresponding heat dissipation effect, the temperature sensor 13 can detect the high temperature and transmit the signal to the control module 12. The control module 12 can control the side of the semiconductor cooling chip 9 close to the fan 5 to cool, and the cooling fan 10 dissipates heat on the heat dissipation surface of the semiconductor cooling chip 9. The air flowing inside the L-shaped air duct 4 is cooled down, improving the heat dissipation effect when the weather is hot and ensuring the stability of the operation of the internal modular control device 2.
[0033] When used in winter, if the internal temperature of the cabinet 1 is too low, the temperature sensor 13 will detect this and control the micro motor 111 to drive the drive gear 112 to rotate, which will drive the driven gear 113 and the linkage rod 8 to flip, thereby causing the semiconductor cooling chip 9 to flip over so that the heat dissipation surface is close to the fan 5. This is used to appropriately heat the inside of the cabinet 1, avoiding the possible performance degradation of components in special low-temperature environments, and further ensuring the effectiveness of its modular control device 2 in special situations.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
