Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an energy metering box with monitoring and temperature control functions. Background Technology

[0002] With the rapid development of power Internet of Things (IoT) technology, electricity metering boxes, as key connection nodes between the power supply network and the user side, integrate high-precision electronic equipment such as smart meters, communication acquisition terminals, load control switches, and power communication modules. These devices have high requirements for the temperature and humidity of the operating environment. Traditional electricity metering boxes usually use simple metal or plastic boxes, achieving basic heat dissipation and ventilation through openings for natural ventilation or the addition of external cooling fans.

[0003] However, in practical applications, the above-mentioned traditional electricity metering boxes have the following problems: Outdoor power distribution environments are complex, with large temperature differences between day and night, and condensation is very likely to occur during humid seasons. If the enclosure is kept sealed to meet IP protection level requirements, internal heat cannot be dissipated, and heat accumulation will cause electronic components to age faster and communication modules to fail due to heat. If ventilation holes are opened for convection heat dissipation, a large amount of external dust, rainwater, insects and high humidity air can easily enter the enclosure, causing short circuits, leakage, or oxidation and corrosion of wiring terminals, which will seriously reduce the reliability and service life of the metering device.

[0004] Existing improved temperature control boxes mostly adopt a single logic of "electric heating" or "forced ventilation". In the high humidity environment of the south, simple heating is not only energy-intensive, but also cannot fundamentally remove water vapor from the box. In the hot and dry season, the fan heat dissipation efficiency is limited by the cross-section of the air duct. Under heavy load operation or strong sunlight exposure, the passive heat dissipation capacity is inadequate and it is difficult to cope with extreme climate conditions.

[0005] Therefore, there is an urgent need for an energy metering box that can ensure a high level of protection and achieve intelligent closed-loop regulation of temperature and humidity, so as to overcome the shortcomings of existing technologies in terms of environmental reliability and active temperature control efficiency. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects: This type of energy metering box with temperature monitoring and control function, through the setting of adjustment mechanism and monitoring sensor, can automatically use a single electric actuator to drive the first shielding component and the second shielding component to perform spatial reverse synchronous linkage according to the real-time temperature and humidity changes inside the box. It realizes intelligent adaptive switching between open window convection heat dissipation under normal climate and closed window physical sealing under harsh climate, improving the IP protection level of the metering box and the operational reliability of the internal high-precision electronic components in complex outdoor environments.

[0018] This type of energy metering box with monitoring and temperature control functions uses a heat transfer mechanism and partitioning components to force the condensation of moisture in the high-humidity air inside the box in a closed dehumidification mode by utilizing the temperature difference between the hot and cold ends formed by the semiconductor cooling chip. At the same time, the partitioning components safely guide and isolate the condensed liquid water into a separate second chamber at the bottom, effectively preventing the liquid water from being heated and evaporated again in the sealed component chamber, thus preventing humidity rebound. This solves the problem of condensation in traditional metering boxes that can easily lead to short circuits or oxidation.

[0019] This type of energy metering box with monitoring and temperature control functions realizes the "turning waste into treasure" of condensate by setting up lifting components and water absorption components in the liquid storage and drainage mechanism. Under high-load conditions such as extreme high temperature exposure during the day, it can drive the sponge with condensate to rise vertically and closely adhere to the heating side surface of the heat transfer mechanism. It utilizes the latent heat of vaporization of water to provide a powerful secondary auxiliary contact water cooling for the heat transfer mechanism, which greatly expands the heat dissipation limit of the passive energy metering box in high temperature and dry environment.

[0020] This type of energy metering box with temperature monitoring and control functions achieves highly integrated mechanical linkage by setting up a speed regulation mechanism and a linkage mechanism. Relying on only one power component as a unified mechanical power source, it successfully overcomes the transmission conflict between "small deflection angle of the damper louvers" and "large linear lifting stroke of the water absorption component". Utilizing a rigid transmission network of gears, racks, and bevel gears, it precisely synchronizes multiple complex tasks such as opening and closing of the ventilation vents, flow channel on / off control, and lifting of the sponges on both sides. This not only avoids the action misalignment caused by multiple actuators, but also greatly simplifies the internal space, significantly reducing the overall construction cost and subsequent maintenance rate of the machine.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Please see Figures 1-13 An energy metering box with temperature monitoring and control functions includes: Box 1, with a first opening 11 through both sides; Two L-shaped plates 6 are respectively disposed inside the box 1 on both sides near the two first openings 11, and the two L-shaped plates 6 separate the two sides of the box 1 into two first cavities 12 respectively. The surfaces of the two L-shaped plates 6 are provided with second openings 61, and the first openings 11, the first cavities 12 and the second openings 61 are connected. Two adjustment mechanisms 2 are respectively disposed in the two first cavities 12, and are used to adjust the opening size of the first port 11 and the second port 61 on the same side; Two heat transfer mechanisms 3 are respectively installed on two L-shaped plates 6 to condense the moisture inside the box 1; Monitoring sensor 8 is installed inside the enclosure 1 to detect the humidity and temperature inside the enclosure 1 in real time.

[0025] Also includes: Two liquid storage and discharge mechanisms 4 are respectively located below the two first cavities 12, for collecting and discharging condensate after being condensed by the heat transfer mechanism 3, and the liquid storage and discharge mechanism 4 has a lifting end that can rise to provide auxiliary cooling to the heat transfer mechanism 3. The speed regulating mechanism 7 has its power input end connected to the regulating mechanism 2 and its power output end connected to the lifting end of one of the liquid storage and discharge mechanisms 4, and is used to synchronously drive the liquid storage and discharge mechanism 4 when the regulating mechanism 2 is running. The linkage mechanism 5 is connected between the lifting end of the speed regulating mechanism 7 and the other liquid storage and discharge mechanism 4, and is used to synchronously drive the other liquid storage and discharge mechanism 4 when the speed regulating mechanism 7 is running.

[0026] It should be noted that, in order to clearly demonstrate the temperature control and monitoring dehumidification structure of the present invention, the accompanying drawings omit the high-precision electronic components such as smart meters, communication acquisition terminals, and load control switches conventionally installed inside the component cavity of the housing 1, as well as their mounting rails. The arrangement of these components is consistent with that of existing power metering boxes, and will not be described in detail here.

[0027] Furthermore, in order to switch between normal heat dissipation and heat preservation and dehumidification of the housing 1, as a preferred embodiment of the present invention, the adjustment mechanism 2 includes a first shielding component 21, a second shielding component 22, a power component 23, a fifth plate 24, and a connecting component 25. The first shielding component 21 is located in the first opening 11, the second shielding component 22 is located in the second opening 61, the two ends of the fifth plate 24 are fixedly connected to the inner wall of the housing 1 and the side wall of the L-shaped plate 6, respectively, one end of the power component 23 is connected to the middle of the L-shaped plate 6, and the other end of the power component 23 is connected to the connecting component 25, the first shielding component 21, and the second shielding component 22. More specifically, by setting the adjustment mechanism 2, it is possible to adaptively switch between the conventional convection heat dissipation mode and the sealed heat preservation and dehumidification mode. The effective air circulation cross-sectional area of ​​the first opening 11 and the second opening 61 is adjusted according to the real-time changes in temperature and humidity inside the box, thus resolving the technical contradiction between "convection heat dissipation and dust and water resistance" inside the outdoor power distribution box 1.

[0028] Furthermore, in order to keep the first opening 11 partially open during normal heat dissipation, and to close the first opening 11 during heat preservation or dehumidification, as a preferred embodiment of the present invention, the first shielding component 21 includes a plurality of first plates 211 and a plurality of first rods 212. Both ends of the plurality of first rods 212 are rotatably connected to the first opening 11, the middle part of the plurality of first rods 212 is fixedly connected to one end of the plurality of first plates 211, the plurality of first plates 211 are all located inside the first opening 11, and the sidewalls of the plurality of first plates 211 near the end of the first rods 212 are provided with a plurality of first grooves 213, and the plurality of first grooves 213 are all connected to the power component 23; More specifically, by setting the first shielding component 21, several first plates 211 can be tilted outward in normal sunny weather to maintain the maximum windward convection section. In rainy or snowy weather, winter low temperature or extreme high humidity environment, the first plates 211 can be driven to rotate and close, thereby physically sealing off the channel for the external harsh environment to invade the first cavity 12 and improving the IP protection level of the enclosure 1.

[0029] Furthermore, in order to keep the second opening 61 partially open during normal heat dissipation, and to fully open the second opening 61 after the first opening 11 is closed for heat preservation and dehumidification, as a preferred embodiment of the present invention, the second shielding component 22 includes a plurality of second plates 221, a plurality of second rods 222, and a plurality of half gears 223. Both ends of the plurality of second rods 222 are rotatably connected to the second opening 61, the middle part of the plurality of second rods 222 is fixedly connected to one end of the plurality of second plates 221, the plurality of second plates 221 are all located inside the second opening 61, the outer wall of one end of the plurality of second rods 222 is fixedly connected to the axis of the plurality of half gears 223, and the plurality of half gears 223 are all connected to the power component 23; More specifically, by setting a second shielding component 22, while the first shielding component 21 is closed to block external cold air or rainwater, several second plates 221 can be simultaneously driven to rotate to a vertically fully open state (90°), thereby maximizing the communication between the first cavity 12 and the inside of the element cavity, so as to smoothly guide the high humidity air accumulated in the element cavity to the heat transfer mechanism 3 for centralized condensation and dehumidification.

[0030] Furthermore, in order to enable switching between normal heat dissipation and heat preservation / dehumidification, as a preferred embodiment of the present invention, the power assembly 23 includes a sixth plate 232, an electric actuator 233, two first rack plates 231, a plurality of fourth blocks 236, a plurality of first spur gears 234, and a plurality of seventh rods 235. The number of fourth blocks 236 is the same as the total number of first plates 211 and second plates 221. The number of first spur gears 234 and seventh rods 235 is the same, and the number of both first spur gears 234 and seventh rods 235 is not less than the number of fourth blocks 236. The outer wall of 233 is fixedly connected to the middle of the fifth plate 24, the output end of the electric push rod 233 is fixedly connected to the middle of the sixth plate 232, the two ends of the sixth plate 232 are fixedly connected to the upper ends of the two first rack plates 231 respectively, one end of several fourth blocks 236 is fixedly connected to the inner wall of the box 1 and the side wall of the L-shaped plate 6 respectively, the other end of several fourth blocks 236 is fixedly connected to one end of several seventh rods 235 respectively, the other end of several seventh rods 235 is fixedly connected to the shaft of several first straight gears 234 respectively, and several first straight gears 234 mesh with the two first rack plates 231 respectively; More specifically, by setting up the power component 23, using a single electric actuator 233 as a unified mechanical power source, and with the rigid transmission of the first rack plate 231 and the first spur gear 234, the linear lifting and reciprocating motion of the electric actuator 233 is converted into the coaxial deflection motion of multiple plates, thereby realizing the reverse hard synchronous switching of the first blocking component 21 and the second blocking component 22 in space, avoiding the action lag or misalignment caused by independent electric control separate execution.

[0031] Furthermore, in order to drive the liquid storage and discharge mechanism 4 simultaneously using only the power source of the power assembly 23, as a preferred embodiment of the present invention, the connecting assembly 25 includes a sixth rod 251, a second rack plate 252, and a second spur gear 253. One end of the sixth rod 251 is fixedly connected to the side wall of the sixth plate 232, and the other end of the sixth plate 232 is fixedly connected to one end of the second rack plate 252. The second spur gear 253 is connected to the speed regulating mechanism 7, and the second rack plate 252 meshes with the second spur gear 253. More specifically, by setting up the connecting component 25, the rigid meshing transmission between the second rack plate 252 and the second spur gear 253 is used to mechanically divert the linear displacement energy generated when the power component 23 switches the air duct to the speed regulating mechanism 7. This realizes the composite mechanical task of simultaneously controlling the lifting and lowering of the liquid storage and discharge mechanism 4 by the same power source in a very short time when adjusting the valve opening, thereby improving the overall energy efficiency ratio of the machine.

[0032] Furthermore, in order to condense and discharge the high humidity in the part of the cabinet 1 where various components (such as power meters) are installed during dehumidification, as a preferred embodiment of the present invention, the heat transfer mechanism 3 includes a frame 32, two heat-conducting fins 31 and several semiconductor cooling chips 33. The surface of the L-shaped plate 6 is provided with a third opening 62 located below the second opening 61. The outer wall of the frame 32 is fixedly connected to the inner wall of the third opening 62. The two sides of the third opening 62 are respectively fixedly connected to one side of the two heat-conducting fins 31. The other sides of the two heat-conducting fins 31 are respectively located on both sides of the L-shaped plate 6. The outer walls of the several semiconductor cooling chips 33 are all fixedly connected to the inner wall of the frame 32. The cooling ends of the several semiconductor cooling chips 33 are all facing the heat-conducting fins 31 on the side close to the internal component cavity of the cabinet 1. The heating ends of the several semiconductor cooling chips 33 are all facing the heat-conducting fins 31 located inside the first cavity 12. More specifically, by setting up a heat transfer mechanism 3, the temperature difference between the hot and cold ends formed by several semiconductor cooling chips 33 under the power-on state is used to rapidly reduce the surface temperature of the heat-conducting fins 31 located on one side of the element cavity to below the dew point to force condensation and liquefaction of high-humidity air, while the heat-conducting fins 31 located on the side of the first cavity 12 release heat for convection drying, thereby achieving highly reliable, maintenance-free microenvironment "condensation dehumidification" and heat micro-balance.

[0033] Furthermore, in order to detect the temperature and humidity in the component mounting area of ​​the enclosure 1 in a timely manner, as a preferred embodiment of the present invention, the monitoring sensor 8 is a temperature and humidity sensor; More specifically, by setting the monitoring sensor 8 as a temperature and humidity sensor, the real-time collected internal temperature and relative humidity values ​​of the component cavity can be converted into standard electrical signals and uploaded to the control core. This serves as the decision-making basis for the closed-loop logic control of triggering the electric push rod 233 to change track and direction, starting and stopping the semiconductor cooling chip 33, and subsequently the periodic lifting and lowering of the water-absorbing sponge 472 to assist in heat dissipation.

[0034] It should be noted that, in order to achieve automated control, the power metering box of the present invention also includes a main control module (such as a PLC controller, a microcontroller or a microprocessor) and a power supply module. The monitoring sensor 8, the electric actuator 233 and the semiconductor cooling chip 33 are all electrically connected to the main control module. The main control module receives the real-time temperature and humidity signals collected by the monitoring sensor 8 and has built-in temperature and humidity threshold judgment logic. When the temperature and humidity data reach the preset severe weather or high humidity / high temperature threshold, the main control module outputs the corresponding control signal to the electric actuator 233 and the semiconductor cooling chip 33 to drive them to perform the corresponding opening, closing, lifting or cooling / heating actions. The power supply module is used to provide working voltage for the above-mentioned electrical equipment and the power metering components inside the box 1.

[0035] Furthermore, in order to collect and discharge the condensate after it has been condensed by the heat transfer mechanism 3, and also to use this condensate to assist in heat dissipation of the heat-conducting fins 31 of the heat transfer mechanism 3 at high temperatures, as a preferred embodiment of the present invention, the liquid storage and discharge mechanism 4 includes a liquid receiving hopper 41, a pipe body 42, a lifting assembly 43, a partitioning assembly 44, a pressing assembly 45, a water absorption assembly 47, a fifth block 48, an on / off assembly 49, and two reset assemblies 46. A fourth opening 63 located below the third opening 62 is provided through the surface of the L-shaped plate 6. One end of the liquid receiving hopper 41 is located below the heat-conducting fins 31 on the side away from the first opening 11. The outer wall of the other end of the liquid receiving hopper 41 is fixedly connected to the inner wall of the fourth opening 63. The lower end of the partitioning assembly 44 is fixedly connected to the bottom surface of the first cavity 12, and the partitioning assembly 44... A second cavity 401, which communicates with the inside of the liquid receiving hopper 41, is separated between the L-shaped plate 6 and the box body 1. One end of the water absorption component 47 is located inside the second cavity 401. The other end of the water absorption component 47 is connected to one end of the pressing component 45 and one end of the lifting component 43. The other end of the pressing component 45 is connected to the partition component 44. The other end of the lifting component 43 is connected to one end of the fifth block 48. The other end of the fifth block 48 is fixedly connected to the inner wall of the box body 1. The upper ends of the two reset components 46 are connected to the L-shaped plate 6. The lower ends of the two reset components 46 are connected to the upper end of the on / off component 49. The lower end of the on / off component 49 is located between the liquid receiving hopper 41 and the second cavity 401. One end of the tube body 42 is fixedly connected to the outer wall of the box body 1. The tube body 42 communicates with the second cavity 401, and a valve is provided inside the tube body 42. More specifically, by setting up the liquid storage and drainage mechanism 4, during the condensation and dehumidification stage, the condensate can be drained in one direction without power through the liquid receiving hopper 41 and stored offline in the independent second chamber 401 at the bottom. During the high-temperature heat dissipation cycle, this part of the condensate can be mechanically adsorbed and lifted and transported to the heat-generating side. The latent heat of vaporization of water is used to provide secondary auxiliary contact water cooling for the heat transfer mechanism 3, which greatly expands the heat dissipation limit of the box 1 in the dry and exposed environment.

[0036] It should be noted that, in order to achieve intelligent and automatic discharge of condensate, the valve installed inside the pipe body 42 is a solenoid valve, which is electrically connected to the main control module. A liquid level sensor is also installed on the bottom or side wall inside the second cavity 401, which is electrically connected to the main control module and is used to monitor the height of the condensate stored inside the second cavity 401 in real time.

[0037] In actual operation, the main control module has a built-in drainage control logic: when the liquid level sensor detects that the condensate level in the second chamber 401 has reached the preset liquid level value, and the monitoring sensor 8 does not send a high temperature heat dissipation signal, the main control module sends an opening electrical signal to the solenoid valve, the solenoid valve opens automatically, and the condensate in the second chamber 401 is automatically discharged to the outside of the box 1 through the pipe 42; when the liquid level sensor detects that the water level has dropped to the preset liquid level value, the main control module controls the solenoid valve to close, maintaining the sealing state of the second chamber 401 again to prevent external moisture from flowing back.

[0038] Furthermore, in order to collect the condensate after condensation by the heat transfer mechanism 3, as a preferred embodiment of the present invention, the partitioning component 44 includes a fourth plate 442 and two third plates 441. The lower ends of the two third plates 441 are fixedly connected to the bottom surface of the inner wall of the box 1, and the upper ends of the two third plates 441 are fixedly connected to the bottom surface of the fourth plate 442. A fifth port 443 and a sixth port 444 are provided through the upper surface of the fourth plate 442. The second cavity 401 is located between the fourth plate 442 and the two third plates 441. The sixth port 444 is connected to the liquid receiving hopper 41 and the second cavity 401. The switching component 49 is located at the connection between the sixth port 444 and the liquid receiving hopper 41. The lifting component 43 and the water absorption component 47 are located inside the fifth port 443. More specifically, by setting up the partition component 44, the fourth plate 442 separates a relatively independent and closed second cavity 401 as a water collection pool on the bottom surface of the first cavity 12, so that the precipitated liquid condensate is physically isolated from the main airflow channel, fundamentally preventing the liquid water from being heated and evaporated again in the sealed component cavity, thus preventing the humidity from rebounding.

[0039] Furthermore, in order to enable the water absorption component 47 to rise and assist the heat-conducting fins 31 located on one side of the first cavity 12 in order to dissipate heat when there is condensate inside the partition component 44 and the temperature inside the entire box 1 is high, as a preferred embodiment of the present invention, the lifting component 43 includes a threaded rod 431 and a second column 432. The upper end of the threaded rod 431 is connected to the speed regulating mechanism 7, and the upper end of the threaded rod 431 is also rotatably connected to the inner wall of the fifth block 48. The lower end of the threaded rod 431 is threadedly connected to the inner wall of the second column 432, and the side wall of the second column 432 is connected to the water absorption component 47. More specifically, by setting up the lifting component 43, the high-speed, low-torque rotational power output by the speed regulating mechanism 7 is stably converted into a large-stroke vertical linear displacement of the water-absorbing component 47 through the cooperation of the screw rod 431 and the second column 432. This provides sufficient and rigid mechanical lifting force to vertically push the water-absorbing sponge 472 to the precise fitting position.

[0040] Furthermore, in order to reduce the backflow of water vapor from the condensate inside the second cavity 401 to the components of the housing 1 during normal heat dissipation, and also to facilitate the collection of condensate when dehumidification is required, as a preferred embodiment of the present invention, the on / off assembly 49 includes a frame 491 and a sealing plate 492. One side of the upper surface of the sealing plate 492 is fixedly connected to the lower end of the frame 491. The upper end of the frame 491 passes through the sixth port 444 and is connected to the pressing assembly 45 and the two reset assemblies 46. The outer wall of the sealing plate 492 is slidably connected to the inner wall of the liquid receiving hopper 41 near the second cavity 401. More specifically, by setting the on / off component 49, the sliding displacement of the sealing plate 492 at the sixth port 444 is used to realize the physical on / off control of the water collection path under different climatic conditions. In the normal heat dissipation mode, the second cavity 401 is sealed by mechanical compression to block the backflow of external moisture and impurities. In the dehumidification mode, the channel is opened to ensure smooth flow of condensate.

[0041] Furthermore, in order to collect condensate into the second cavity 401 when the water-absorbing component 47 rises to assist in heat dissipation of the heat-conducting fins 31, and also to seal the channel between the liquid receiving hopper 41 and the second cavity 401 when the water-absorbing component 47 descends into the second cavity 401 to absorb water or stops operating, as a preferred embodiment of the present invention, the pressing component 45 includes a first block 451 and a second block 452. One end of the first block 451 is connected to the water-absorbing component 47, and one end of the second block 452 is fixedly connected to one end of the frame 491 that passes through the sixth opening 444. The adjacent ends of the first block 451 and the second block 452 abut against each other. More specifically, by setting up the pressing component 45, the mechanical interference between the first block 451 and the second block 452 in the vertical space counteracts each other. When the water absorption component 47 returns to the bottom water absorption position, the frame 491 of the on / off component 49 is mechanically pressed down to lock it, eliminating the need for additional electronic actuators and sensor components.

[0042] Furthermore, in order to automatically open the channel between the liquid receiving hopper 41 and the second cavity 401 when the water absorption assembly 47 rises from inside the second cavity 401 to assist in heat dissipation of the heat-conducting fins 31, as a preferred embodiment of the present invention, the reset assembly 46 includes a third block 461, a spring 462 and a sixth block 463. One side of the third block 461 is fixedly connected to one end of the frame 491 through the sixth opening 444, the other side of the third block 461 is fixedly connected to one end of the spring 462, the other end of the spring 462 is fixedly connected to one side of the sixth block 463, and one end of the sixth block 463 is fixedly connected to one side of the L-shaped plate 6. More specifically, by setting the reset component 46 and utilizing the pre-tightening restoring force of the spring 462, when the water absorption component 47 is lifted upward with the threaded rod 431 and disengages from the bottom interference position, the frame 491 can automatically slide upward under the tension of the spring 462, thereby achieving adaptive opening of the condensate flow channel without any external electronic command.

[0043] Furthermore, in order to absorb the condensate in the second cavity 401 during dehumidification and use it for subsequent auxiliary heat dissipation, as a preferred embodiment of the present invention, the water absorption assembly 47 includes a seventh plate 471 and a sponge 472. One side of the seventh plate 471 is fixedly connected to one side of the sponge 472, and the other side of the sponge 472 abuts against the heat-conducting fins 31 located on one side of the first cavity 12. The upper surface of the seventh plate 471 is fixedly connected to one end of the first block 451, and one side of the seventh plate 471 is fixedly connected to the side wall of the second column 432. The outer walls of both the seventh plate 471 and the sponge 472 abut against the inner wall of the fifth opening 443, and the outer wall of the seventh plate 471 abuts against the inner wall of the first cavity 12. More specifically, by setting up the water absorption component 47, the seventh plate 471 provides rigid limiting and guiding support for the back of the sponge 472 on the entire plane, ensuring that the sponge 472 will not twist, deform or slip during high-frequency reciprocating motion. Furthermore, when it rises to the top, the sponge 472, which has absorbed enough water, can be evenly and tightly spread and pressed onto the surface of the heat-conducting fins 31, thereby achieving efficient capillary phase change heat conduction.

[0044] Furthermore, since the first shielding component 21 and the second shielding component 22 rotate at a small angle during adjustment, while the water absorption component 47 needs to rise a large distance, in order to ensure the consistency of the stroke, as a preferred embodiment of the present invention, the speed regulating mechanism 7 includes a gear accelerator 71, a fourth bevel gear 72, a third bevel gear 73, and a first column 74. One end of the first column 74 is fixedly connected to the inner wall of the housing 1, and the other end of the first column 74 is fixedly connected to the outer wall of the gear accelerator 71. The input end of the gear accelerator 71 is fixedly connected to the shaft of the second spur gear 253, and the output end of the gear accelerator 71 is connected to the linkage mechanism 5. The other end of the linkage mechanism 5 is connected to the third bevel gear 73. The shaft of the fourth bevel gear 72 is fixedly connected to the upper end of the threaded rod 431, and the fourth bevel gear 72 meshes with the third bevel gear 73. More specifically, by setting up the speed regulation mechanism 7, the gear accelerator 71 converts the small angular displacement of the second spur gear 253 into the high-speed, multi-turn continuous rotation of the threaded rod 431, successfully overcoming and reconciling the transmission conflict between the small deflection angle of the damper louvers (only requiring fine-tuning of displacement) and the large linear lifting stroke of the water absorption component 47 (requiring long-distance lifting) under the same power source.

[0045] It is important to note here that the gear accelerator 71 is a commercially available, conventional multi-stage gear speed increaser or planetary gear speed increaser mechanism. Internally, it has a multi-stage meshing speed increaser gear set. Utilizing the mechanical principle of a large gear driving a small gear, it amplifies the small-angle, low-speed rotational power input from the second spur gear 253 according to a predetermined transmission ratio, converting it into high-speed, multi-turn rotational power at the output end. This satisfies the long-stroke lifting drive requirement of the threaded rod 431. This is a mature mechanical transmission component, and its specific internal gear arrangement will not be elaborated further. Furthermore, to eliminate the cost of a speed regulating mechanism 7, in a preferred embodiment of the present invention, the linkage mechanism 5 includes a third rod 51, a fourth rod 54, a fifth rod 55, two first bevel gears 52, and two second bevel gears 53. One end of the fifth rod 55 is fixedly connected to the output end of the gear accelerator 71. The fifth rod 55 and the fourth rod 54 are parallel and are located within the two first cavities 12, respectively. The same end of the fifth rod 55 and the fourth rod 54 is connected to the gear accelerator 71 within the two first cavities 12. The third bevel gear 73 is fixedly connected to the shaft. The other ends of the fifth rod 55 and the fourth rod 54 are rotatably connected to the housing 1. The shafts of the two second bevel gears 53 are fixedly connected to the ends of the two fifth rods 55 and the fourth rod 54 near the housing 1, respectively. The two ends of the third rod 51 are located in the two first cavities 12, respectively. The two ends of the third rod 51 are rotatably connected to the two L-shaped plates 6, respectively. The two ends of the third rod 51 are fixedly connected to the shafts of the two first bevel gears 52, respectively. The two first bevel gears 52 mesh with the two second bevel gears 53, respectively. More specifically, by setting up a linkage mechanism 5, the output torque of the single-sided speed regulating mechanism 7 is rigidly transmitted across the cavity to the fourth rod 54 on the other side by using the third rod 51 across the symmetrical bevel gear transmission chain at the bottom of the box 1. This achieves the synchronous operation of the double-sided water absorption components 47 symmetrically arranged on the left and right sides of the box 1 using only one set of gear accelerator 71 and electric push rod 233, which greatly simplifies the internal mechanical space and reduces the hardware construction cost.

[0046] Working principle: During normal weather use, several first plates 211 within the first shielding assembly 21 are tilted 45° outwards from the housing 1 with the first rod 212 as the axis. At the same time, several second plates 221 within the second shielding assembly 22 are also tilted 45° towards the component cavity inside the housing 1 with the second rod 222 as the axis. At this time, the external environment, the first opening 11, the first cavity 12, the second opening 61 and the inside of the component cavity are connected in sequence to form a smooth convection airflow channel, thereby meeting the normal heat dissipation requirements of the components inside the housing 1.

[0047] When it rains or the weather is cold, in order to prevent rainwater from entering or the performance of internal components from being affected by the low temperature, the electric push rod 233 in the power assembly 23 is activated. The electric push rod 233 moves downward and pushes the sixth plate 232 down. The sixth plate 232 carries the first rack plate 231 down and engages with it to drive the first spur gear 234 to rotate. The first spur gear 234 then drives the first plate 211 to rotate through the first groove 213, completely closing the first opening 11.

[0048] At the same time, another first rack plate 231, in conjunction with the remaining gear mechanism, synchronously drives the half gear 223 on the second plate 221 to rotate, so that the second plate 221 is fully extended to 90°. At this time, the first cavity 12 is isolated from the external environment, but the first cavity 12, the second port 61 and the inside of the component cavity are still connected.

[0049] When humidity is high during the rainy season, several semiconductor cooling chips 33 of the heat transfer mechanism 3 are activated. The semiconductor cooling chips 33, together with the heat-conducting fins 31 on both sides, absorb heat and condense moisture on one side of the element cavity, while simultaneously heating the heat radiated from one side of the first cavity 12, thereby ensuring that the interior of the box 1 is in a dry and suitable temperature state.

[0050] Furthermore, as the electric actuator 233 moves downward and the adjusting plate flips, the sixth plate 232 simultaneously moves downward along with the sixth rod 251 and the second rack plate 252 of the connecting assembly 25. The downward movement of the second rack plate 252 engages and drives the second spur gear 253 to rotate. Subsequently, after the speed-increasing processing of the gear accelerator 71 in the speed regulation mechanism 7, it drives the fifth rod 55 and the third bevel gear 73 at its end to rotate at high speed.

[0051] Next, the third bevel gear 73 meshes and drives the fourth bevel gear 72 to rotate, which in turn drives the threaded rod 431 to rotate. The threaded rod 431 drives the second column 432 to rise through the threaded transmission, thereby lifting the seventh plate 471, the sponge 472 and the first block 451 of the water absorption assembly 47 together upward.

[0052] As the first block 451 rises, it no longer presses down on the second block 452. At this time, the frame 491 of the switching component 49 springs upward under the pulling force of the two springs 462, pulling the sealing plate 492 away from the connection between the liquid receiving hopper 41 and the second cavity 401, automatically opening the water passage. The water droplets generated by the condensation of the heat transfer mechanism 3 fall into the liquid receiving hopper 41 under the action of gravity and flow into the second cavity 401 through the fourth port 63 for storage and later use.

[0053] During the rising process of the sponge 472, since the seventh plate 471 abuts against the inner wall of the box 1, the sponge 472 can only rise vertically and will not deflect. After the sponge 472 rises, it will closely adhere to the heat-conducting fins 31 that are heated on one side of the first cavity 12. The water adsorbed in the sponge 472 evaporates when heated, thereby providing forced auxiliary cooling and heat dissipation for the heat-conducting fins 31.

[0054] Furthermore, in the event of extreme high temperatures during the day, the electric actuator 233 can be periodically opened and closed by the control system to drive the sponge 472 to rise and fall periodically to assist the heat-conducting fins 31 in dissipating heat. If there is too much condensate inside the second cavity 401, some of the liquid can be discharged by manually opening the valve inside the tube 42.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended technical solutions and their equivalents.
