Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and more particularly to an intelligent integrated distribution box. Background Art

[0002] With the development of intelligent technology, traditional distribution boxes are gradually evolving towards integration and intelligence. Intelligent integrated distribution boxes integrate functions such as data acquisition, remote communication and intelligent control. They can provide real-time feedback on operating status, significantly improving the efficiency and accuracy of power management, and have become a key component of modern power systems.

[0003] Amid the rapid development of solar energy, desert regions, with their abundant sunshine, have become ideal locations for solar equipment. However, as essential universal connection equipment for power systems, distribution boxes face the erosion of the desert's changing day and night environments. Heat dissipation vents, serving as pathways connecting the inside and outside, are susceptible to daytime sand and dust carrying floating particles that invade the equipment. At night, the dramatic negative temperature difference induces condensation and moisture infiltration. This compound pollution not only contaminates electrical components but also causes insulation degradation, a surge in contact resistance, and the risk of arcing, seriously threatening the life of the equipment.

[0004] To this end, this application proposes an intelligent integrated distribution box to solve the above problems. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent integrated distribution box, comprising a cabinet body, a heat dissipation outlet opened on the side wall of the cabinet body, and a protective box covering the outside of the heat dissipation outlet, wherein a heat dissipation unit is provided at the heat dissipation outlet; a dust and moisture-proof component is installed in the protective box, and the dust and moisture-proof component is connected to the driving and rotating component installed on the top wall of the protective box; the dust and moisture-proof component comprises: a plurality of guide flaps arranged at equal intervals in the protective box and a central axis rod fixed with the guide flaps and connected to the driving and rotating component, the bottom of the protective box is connected to a sewage collecting and draining bucket for discharging dust and condensed water fallen on the guide flaps; the guide flaps have two working positions: when the external temperature is higher than the set threshold value, the guide flaps maintain an unfolded state, and the middle inclined surface thereof blocks the dust and guides it to slide; when the external temperature is lower than the set threshold value, the guide flaps deflect in the same direction, and the bent surfaces at both ends form a double water-blocking barrier to prevent moisture from invading the heat dissipation outlet.

[0007] In a new embodiment, the guide fold is provided with an auxiliary component that provides sand blocking and dehumidification for the guide fold, and the auxiliary component includes an aluminum panel and a hydrophilic breathable membrane: the guide fold includes an angled section in the middle and a bent section at the front and rear parts; an aluminum panel is installed on the windward side of the angled section, and a plurality of intercepting columns are installed at equal intervals on the wall surface of the aluminum panel, and a hydrophobic membrane is provided on the aluminum panel and the intercepting columns. The airflow containing sand and dust hits the gap between adjacent intercepting columns and is intercepted, and slides along the surface of the hydrophobic membrane; the same side wall surfaces of the front and rear bent sections are attached with a hydrophilic breathable membrane, and a heating plate is buried in the bent section, and the heating plate is in thermal contact with the hydrophilic breathable membrane, and the humid airflow passes through the front and rear hydrophilic breathable membranes twice in sequence to intercept moisture, and at the same time the heating plate maintains the membrane surface temperature.

[0008] In a new embodiment, the driving assembly includes: a worm gear, fixedly mounted on the top of the central shaft; a worm segment, horizontally arranged on one side of the worm gear, and meshingly connected with the corresponding worm gear; a connecting rod, rotatably mounted on the top of the protective box, and a plurality of worm segments are fixedly mounted on the connecting rod at equal intervals, and one end of the connecting rod is fixedly connected to the output end of the driving motor located at the top of the protective box.

[0009] In a new embodiment, the protective box is provided with a temperature control component that provides a trigger signal for the driving component, and the temperature control component includes a temperature detector and a microcontroller. An inclined outer shell cover is installed on the top of the protective box; a temperature detector is installed on the inclined outer shell cover, and a microcontroller is installed on the bottom wall of the inclined outer shell cover. The temperature detector and the microcontroller are electrically connected. The microcontroller compares the temperature with the set threshold and outputs a control signal to the driving motor to switch the working position of the guide flap.

[0010] In a new embodiment, a curved filter plate is installed on the outer side of the air inlet of the protective box, and the mesh surface of the curved filter plate is a continuously undulating wave-like structure.

[0011] In a new embodiment, the bottom surface of the protection box is provided with two discharge ports with its central axis as the axis of symmetry, and the discharge ports are connected to the inlet of the sewage collecting and draining bucket.

[0012] In a new embodiment, a sealing plate is rotatably installed on the side wall of the sewage collecting and draining bucket, the top contact surface of the sealing plate is covered with a polytetrafluoroethylene coating, and a rubber sealing strip is embedded in the top edge thereof. The bottom of the sealing plate is rotatably connected to the rod body of the hydraulic rod, and the cylinder body of the hydraulic rod is rotatably installed on the side wall of the sewage collecting and draining bucket.

[0013] In a new embodiment, the heat dissipation unit adopts the cooperation of a mounting frame, a heat dissipation fan and a filter to guide and discharge the heat in the cabinet, and a cabinet door with a sealed cover is installed at the front of the cabinet.

[0014] Beneficial effects: Compared with the existing technology, the advantages of the present invention are: 1. This application aims at the characteristics of significant differences in day and night environments in desert areas, with high temperatures and dust during the day and low temperatures and easy condensation at night, and provides a day and night dynamic protection mechanism for the heat dissipation outlet of the distribution box, achieving precise adaptation of dust protection during the day and moisture resistance at night, avoiding pollution of electrical components, reducing insulation degradation, contact resistance surge and arc risk, and extending equipment life. It not only gives full play to the unmanned management advantages of the intelligent distribution box and improves the autonomous operation efficiency of the equipment, but also significantly enhances the comprehensive adaptability of the distribution box to extreme environments, providing key guarantees for the stable operation of power equipment in special scenarios such as deserts.

[0015] 2. By setting up a protective box outside the heat dissipation port of the distribution box and combining it with the guide flaps inside the box, integrated moisture-proof and dust-proof treatment is achieved. The external ambient temperature is monitored in real time by relying on the temperature detector on the oblique outer cover of the top of the protective box. The microcontroller compares and analyzes the real-time temperature with the threshold value by presetting high and low temperature thresholds, and automatically controls the guide flaps to switch the working position, so that the guide flaps can switch to the anti-sand and dust mode or the moisture-proof mode according to the changes in the external temperature, realizing intelligent and automatic adjustment of the protection mode.

[0016] 3. When the external temperature is higher than the set threshold (anti-sand and dust mode), the airflow containing sand and dust first passes through the curved filter plate at the air inlet of the protective box. Its wavy mesh surface can initially filter out large particles of sand and dust. After the remaining airflow enters the protective box, it will hit the aluminum panel on the windward side of the angled section of the guide fold. The multiple intercepting columns on the aluminum panel form a strip-shaped blocking barrier to further intercept small and medium-sized particles of sand and dust. At the same time, the hydrophobic film on the surface of the aluminum panel and the intercepting columns can effectively reduce the adhesion of sand and dust, so that the intercepted sand and dust slide down the slope of the angled section under the action of gravity and airflow impact, and enter the sewage collection and drainage bucket through the discharge port at the bottom of the protective box for discharge, thereby improving the efficiency of sand and dust interception and discharge.

[0017] 4. When the external temperature is lower than the set threshold (moisture-proof mode), the humid air flow enters the protective box and first contacts the hydrophilic breathable membrane on the surface of the front bending section. The membrane layer absorbs water vapor by virtue of its hydrophilic properties, while retaining a small amount of air circulation space. The trace moisture not intercepted by the front membrane layer will be intercepted again by the hydrophilic breathable membrane of the rear bending section, forming a double-step water-blocking barrier, which greatly reduces the risk of moisture intrusion. In addition, the heating plate buried in the bending section is in thermal contact with the hydrophilic breathable membrane after being energized, so that the membrane surface temperature is always higher than the external environment, effectively preventing condensation on the membrane surface due to low temperature. After the intercepted water vapor condenses into liquid water on the membrane surface, it slides down along the inclined surface of the bending section under the action of gravity, and finally enters the sewage collection and drainage bucket through the discharge port for discharge, realizing the discharge treatment of condensed water.

[0018] 5. The sewage collecting and draining bucket drives the sealing plate to rotate through the hydraulic rod, which can realize the discharge on demand. It is especially suitable for remote desert areas and can significantly reduce the frequency of manual maintenance. The coordination between the discharge port and the sewage collecting and draining bucket forms a closed-loop processing process of collection, temporary storage and discharge. It can promptly remove the sand and condensed water intercepted by the guide flap, avoid the long-term accumulation of dirt in the protection box and cause reverse pollution, and ensure the continuous and stable operation of the protection system.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present application provides an intelligent integrated distribution box to solve the problem that the heat dissipation vents of the distribution box are invaded by dust during the day and penetrated by condensation moisture induced by the negative temperature difference at night under the difference between day and night environments of high temperature and dust and low temperature and easy condensation, leading to electrical component contamination, insulation degradation, contact resistance surge and arc risk, thereby threatening the life of the equipment. When in use, a dynamic protection mechanism is provided for the heat dissipation vents of the distribution box during the day and night, thereby avoiding contamination of electrical components, reducing insulation degradation, contact resistance surge and arc risk, and extending the life of the equipment.

[0034] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows.

[0035] For example 1, please refer to Figures 1-11 The embodiment of the present application provides an intelligent integrated distribution box, comprising a cabinet 1, a heat dissipation vent 2 opened on the side wall of the cabinet 1, and a protective box 3 covering the outside of the heat dissipation vent 2, wherein a heat dissipation unit 4 is provided at the heat dissipation vent 2; a dust and moisture proof component 5 is installed in the protective box 3, and the dust and moisture proof component 5 is connected to a driving and rotating component 6 installed on the top wall of the protective box 3; the dust and moisture proof component 5 comprises: a plurality of guide flaps 51 arranged at equal intervals in the protective box 3 and a central axis 52 fixedly connected to the guide flaps 51 and connected to the driving and rotating component 6; the bottom of the protective box 3 is connected to a sewage collecting and draining bucket 7 for removing sand, dust and condensed water falling on the guide flaps 51; the guide flaps 51 have two working positions: when the external temperature is higher than the set threshold, the guide flaps 51 remain in the unfolded state, and the central inclined surface thereof blocks sand and dust and guides it to slide down; when the external temperature is lower than the set threshold, the guide flaps 51 deflect in the same direction, and the bent surfaces at both ends thereof form a double water-blocking barrier to prevent moisture from invading the heat dissipation vent 2.

[0036] Furthermore, the heat dissipation unit 4 adopts the cooperation of a mounting frame, a heat dissipation fan and a filter to guide and discharge the heat in the cabinet 1. A sealed cabinet door is installed at the front of the cabinet 1.

[0037] The preferred implementation method of this scheme is to configure a protective box 3 for the heat dissipation port 2 of the distribution box in view of the difference between the day and night environment in the desert, which is high temperature and dusty during the day and low temperature and easy condensation at night. The protective box 3 can automatically switch the working mode and the protection effect according to the external temperature, and realize dynamic adaptation of preventing dust during the day and blocking moisture at night. It can not only reflect the intelligent unmanned management of the distribution box and improve the operation efficiency, but also reflect the comprehensive adaptability of the distribution box to different external environments.

[0038] The specific dust and moisture-proof operation process of the distribution box is as follows: First, a temperature detector 91 on the oblique outer cover of the protective box 3 monitors the external ambient temperature in real time and transmits the data to the microcontroller 92. The microcontroller 92 presets two temperature thresholds (e.g., a high temperature threshold of 30°C and a low temperature threshold of 15°C). By comparing the real-time temperature with the thresholds, the microcontroller 92 outputs a control signal to the driving assembly 6, thereby determining the operating position of the guide flap 51. Second, the microcontroller 92 activates the drive motor, which rotates the worm segment 62 on the connecting rod 63. The worm segment 62 engages with the worm wheel 61, which in turn drives the central shaft 52 to rotate, causing all the guide flaps 51 fixed to the central shaft 52 to rotate, thereby switching the guide flaps 51 between the dust and sand protection mode and the moisture protection mode. Anti-dust mode: When the external temperature is higher than the set threshold, the external dust-containing airflow first passes through the curved filter plate 10 at the air inlet of the protective box 3. The wavy mesh initially filters large particles of dust. After the remaining airflow enters the protective box 3, it hits the aluminum panel 81 on the windward side of the bevel section 511 on the guide fold 51. The multiple interception columns 811 installed on the aluminum panel 81 form a strip-shaped barrier to further intercept small and medium-sized particles of dust. At the same time, the hydrophobic film 812 on the surface of the aluminum panel 81 and the interception column 811 To reduce dust adhesion, the trapped dust slides down the inclined surface of the angled section 511 under the impact of gravity and airflow. The sliding dust enters the sewage collection and drainage bucket 7 through the discharge port 31 at the bottom of the protection box 3 and temporarily gathers on the sealing plate 71 on the sewage collection and drainage bucket 7. When cleaning is required, the hydraulic rod 74 pushes the sealing plate 71 to rotate and open (the polytetrafluoroethylene coating 72 reduces friction, and the rubber sealing strip 73 ensures sealing when closed), and the dust is discharged to the outside along the inclined surface of the sealing plate 71; Moisture-proof mode: When the external temperature is lower than the set threshold, the microcontroller 92 controls the drive motor to rotate in the reverse direction, driving the central shaft 52 through the drive assembly 6 to rotate, causing all the guide flaps 51 to deflect in the same direction (the front and rear bent sections 512 are retracted inward to form a relatively closed barrier), thereby switching to moisture-proof mode; When the external humid air flow (humidity formed by condensation at night) enters the protective box 3, it first contacts the hydrophilic breathable membrane 82 on the surface of the front bending section 512. The membrane layer absorbs water vapor due to its hydrophilic property, while allowing a small amount of air to circulate (to avoid complete sealing and heat dissipation failure). The trace moisture not intercepted by the front membrane layer will be intercepted again by the hydrophilic breathable membrane 82 of the rear bending section 512, forming a double stepped water barrier. At the same time, the heating plate 83 embedded in the bending section 512 is energized and heated (cooperating with the hydrophilic breathable membrane 82). Thermal contact), so that the membrane surface temperature is always higher than the external environment, to avoid condensation on the membrane surface due to low temperature (condensation will block the membrane pores and reduce the air permeability and moisture resistance). After the intercepted water vapor condenses into liquid water on the membrane surface, it slides downward along the inclined surface of the bending section 512 due to gravity. The condensed water also enters the sewage collection and drainage bucket 7 through the discharge port 31 and is temporarily stored on the sealing plate 71. When cleaning is needed, the hydraulic rod 74 pushes the sealing plate 71 to open, and the condensed water is discharged to the outside along the inclined surface of the sealing plate 71, to prevent the accumulated water from breeding mold in the protective box 3; It should be noted that in moisture-proof mode, trace amounts of dust-laden airflow may still infiltrate through the narrow flow channel between the bends 512, causing sand and dust to be passively trapped on the surface of the hydrophilic breathable membrane 82. If the remaining sand and dust mix with the condensed water, there is a risk of condensation and clogging the membrane pores. To eliminate this risk, the heating plate 83 maintains the membrane surface temperature at least 5°C above the dew point, accelerating the condensation and sliding of water vapor, minimizing the contact time between sand and water. The transitional mixture of the sliding sand and condensed water (which does not remain on the surface of the sealing plate 71, which has a polytetrafluoroethylene coating 72 with super-hydrophobic and oleophobic properties, and the mixture cannot infiltrate and adhere to the plate surface, so it will not be retained on the surface of the sealing plate 71) is discharged through the discharge port 31 at the bottom of the protective box 3 into the sewage collection and drainage hopper 7. When switching modes or for regular sewage discharge, the sealing plate 71 is forcibly opened by the hydraulic rod 74 to completely discharge the waste to the outside, eliminating the risk of membrane pore blockage.

[0039] Third, heat generated within the cabinet 1 is directed to the heat dissipation vents 2 via the heat dissipation unit 4 (primarily a cooling fan). In dust and sand protection mode, or when the guide flaps 51 are extended, hot air flows directly through the gaps between the guide flaps 51 and is smoothly discharged from the protective box 3. In moisture-proof mode, the inwardly contracted bends 512 create a tortuous channel between adjacent guide flaps 51, blocking the flow of hot air. This slows heat loss and provides a certain degree of insulation at night. Furthermore, the moderately confined hot air accumulates in the heat dissipation vent 2 area, forming a stable heat flow layer that helps block the intrusion of cold, humid air from the outside.

[0040] In summary, the distribution box intelligently switches the working mode of the dust and moisture proof component 5 through the temperature control component 9, supplemented by the arc filter plate 10, the sewage collection and drainage bucket 7 and the drive component 6, and accurately adapts to the desert day and night environment: efficient dust and sewage prevention in high temperature and dry conditions, strict moisture-proof dehumidification and anti-condensation in low temperature and humid conditions, and at the same time ensures continuous heat dissipation of the cabinet 1 through the heat dissipation unit 4.

[0041] See also Figures 6-10 As shown, the guide flap 51 is provided with an auxiliary component 8 for providing sand blocking and dehumidification for the guide flap 51, and the auxiliary component 8 includes an aluminum panel 81 and a hydrophilic breathable membrane 82: the guide flap 51 includes an oblique angle section 511 in the middle and a bending section 512 at the front and rear parts; an aluminum panel 81 is installed on the windward side of the oblique angle section 511, and a plurality of stop columns 811 are installed at equal intervals on the wall surface of the aluminum panel 81, and the aluminum panel 81 and the stop columns 811 are provided with hydrophobic Membrane 812, the airflow containing sand and dust hits the gap between the adjacent intercepting columns 811 and is intercepted, and slides down along the surface of the hydrophobic membrane 812; the same side walls of the front and rear bending sections 512 are attached with a hydrophilic breathable membrane 82, and a heating plate 83 is also buried in the bending section 512, and the heating plate 83 is in thermal contact with the hydrophilic breathable membrane 82. The wet airflow passes through the front and rear hydrophilic breathable membranes 82 twice in turn to intercept moisture, and at the same time the heating plate 83 maintains the membrane surface temperature.

[0042] In a preferred embodiment of this solution, when the dust-laden airflow hits the aluminum panel 81 on the windward side of the angled section 511, the evenly spaced stop bars 811 on the surface of the aluminum panel 81 form a physical grid barrier. Dust particles are trapped in the gaps between adjacent stop bars 811 due to inertial impact. The hydrophobic film 812 on the surface of the aluminum panel 81 and the stop bars 811 reduces the adhesion of the dust, causing the dust to slide down the inclined surface under the impact of gravity and airflow, achieving self-cleaning. Under the moisture-proof function, the humid air flow passes through the hydrophilic breathable membrane 82 on the wall of the front and rear bending sections 512 in turn. The front hydrophilic breathable membrane 82 absorbs part of the water vapor and allows a small amount of air to circulate (to ensure basic heat dissipation), forming the first interception. The rear hydrophilic breathable membrane 82 intercepts the residual moisture to form a double moisture barrier, forming the second interception. The heating plate 83 is buried in the bending section 512 and is in thermal contact with the hydrophilic breathable membrane 82 to maintain the membrane surface temperature always higher than the ambient temperature, preventing the membrane surface from clogging the micropores due to condensation due to low temperature (to ensure air permeability). After the adsorbed water vapor condenses into liquid water on the membrane surface, it slides down the inclined surface due to gravity and is discharged.

[0043] See also Figure 4 and Figure 5As shown, the driving assembly 6 includes: a worm gear 61, fixedly mounted on the top of the central shaft 52; a worm segment 62, horizontally arranged on one side of the worm gear 61, and meshingly connected with the corresponding worm gear 61; a connecting rod 63, rotatably mounted on the top of the protective box 3, and a plurality of worm segments 62 are fixedly mounted on the connecting rod 63 at equal intervals, and one end of the connecting rod 63 is fixedly connected to the output end of the driving motor located at the top of the protective box 3.

[0044] In a preferred implementation manner of this scheme, after the driving motor (located at the top of the protective box 3) is started, its output end drives the connecting rod 63 to rotate synchronously, and multiple worm segments 62 equidistantly fixedly installed on the connecting rod 63 rotate coaxially with the connecting rod 63. Each worm segment 62 is engaged with the worm wheel 61 at the top of the corresponding guide fold 51, and the rotational motion of the worm segment 62 is transmitted to the worm wheel 61 through the engagement, and the worm wheel 61 then drives the central axis 52 to rotate synchronously. All the guide folds 51 are rigidly linked through the central axis 52, and the rotation of the central axis 52 drives all the guide folds 51 to deflect synchronously, thereby realizing switching between the anti-sand and dust mode (expanded) and the moisture-proof mode (folded).

[0045] See also Figure 4 As shown, the protective box 3 is provided with a temperature control component 9 that provides a trigger signal for the driving component 6, and the temperature control component 9 includes a temperature detector 91 and a microcontroller 92; an inclined outer shell cover is installed on the top of the protective box 3; the temperature detector 91 is installed on the inclined outer shell cover, and the microcontroller 92 is installed on the bottom wall of the inclined outer shell cover. The temperature detector 91 and the microcontroller 92 are electrically connected, and the microcontroller 92 compares the temperature with the set threshold and outputs a control signal to the driving motor to switch the working position of the guide flap 51.

[0046] In a preferred embodiment of this solution, a temperature detector 91, installed obliquely on the top of the housing cover, is directly exposed to the external environment, eliminating interference from the housing structure on temperature measurement and allowing real-time acquisition of high-precision temperature data. A microcontroller 92 uses dual-threshold (high / low temperature) logic to determine the operating condition (e.g., dust protection mode is activated when the temperature is above 30°C, and moisture protection mode is activated when the temperature is below 15°C), enabling adaptive switching between day and night desert environments without manual intervention. The microcontroller 92 directly outputs a control signal to the drive motor, which, through the drive assembly 6 (worm gear 61, worm segment 62, and connecting rod 63), causes all guide flaps 51 to deflect synchronously. At the same time, dust / rainwater is prevented from accumulating on the surface of the temperature detector 91 to ensure long-term monitoring accuracy. The microcontroller 92 is built into the bottom wall of the cover to physically isolate external moisture / dust erosion, extend the life of the circuit, and support customized temperature thresholds according to different desert climates (for example, the high temperature threshold can be adjusted to 35°C), thereby improving regional adaptability.

[0047] See also Figure 4 As shown, a curved filter plate 10 is installed on the outer side of the air inlet of the protection box 3, and the mesh surface of the curved filter plate 10 is a continuously undulating wave-like structure.

[0048] In a preferred implementation manner of this scheme, the wavy mesh surface of the curved filter plate 10 forms a continuously undulating curved channel. When the airflow containing sand and dust passes through, large particles of sand and dust are directly intercepted due to inertia hitting the concave surface of the trough. At the same time, the tortuosity of the airflow path also prolongs the residence time of sand and dust on the surface of the curved filter plate 10, thereby improving the interception efficiency. The non-planar structure prevents sand and dust from being evenly accumulated on the filter surface, significantly reducing the risk of clogging of the curved filter plate 10. After the sand and dust hit the concave surface of the trough, they naturally slide down to the bottom of the curved filter plate 10 due to the action of gravity (non-horizontal surfaces are not easy to adhere). When the external airflow hits the convex surface of the wave peak, local turbulence is generated, which helps to shake off the attached sand and dust, thereby reducing the frequency of manual cleaning.

[0049] See also Figure 11 As shown, the bottom surface of the protection box 3 is symmetrically arranged with its central axis, and has two discharge ports 31 , which are connected to the inlet of the sewage collecting and draining bucket 7 .

[0050] For further information, see Figure 11 As shown, a sealing plate 71 is rotatably installed on the side wall of the sewage collecting and draining bucket 7, the top contact surface of the sealing plate 71 is covered with a polytetrafluoroethylene coating 72, and a rubber sealing strip 73 is embedded in the top edge thereof. The bottom of the sealing plate 71 is rotatably connected to the rod body of the hydraulic rod 74, and the cylinder body of the hydraulic rod 74 is rotatably installed on the side wall of the sewage collecting and draining bucket 7.

[0051] In a preferred implementation manner of this scheme, the sealing plate 71 is driven to rotate by the hydraulic rod 74, so that the sewage collecting and draining bucket 7 can be opened on demand (that is, the discharge is started once each time a mode of sand or condensate collection is completed), thereby avoiding the reverse intrusion of external sand and dust due to the long-term opening of the traditional fixed opening discharge port 31. It is particularly suitable for remote desert areas and reduces the frequency of manual maintenance. At the same time, the rubber sealing strip 73 on the top edge of the sealing plate 71 fits tightly against the inner wall of the sewage collecting and draining bucket 7 when closed, and cooperates with the polytetrafluoroethylene coating 72 on the contact surface to ensure the sealing performance (prevent moisture from flowing back from the discharge port 31 to the protective box 3 at night). The discharge port 31 cooperates with the sewage collecting and draining bucket 7 to process the sand and condensate intercepted by the guide flap 51 through a closed-loop process of collection, temporary storage and discharge, thereby avoiding the reverse pollution problem caused by long-term accumulation of dirt in the protective box 3.

[0052] In the second embodiment, based on the first embodiment, the overall structure of the guide flap 51 is optimized to be a continuous curved surface (such as Figure 12 As shown in FIG5 ), while retaining the functional divisions of the bevel section 511 and the bend section 512, structural integration is achieved through curved surface transition. The specific workflow is as follows: First, anti-sand and dust mode (such as Figure 12As shown in 12-1 , the middle part of the guide fold 51 is still the original aluminum panel 81, which directly serves as the impact surface (the independent aluminum panel 81 is eliminated). The surface is evenly spaced with intercepting columns 811 and is fully covered with a hydrophobic film 812 (omitted in the figure). The airflow is guided by the front bending section 512 and directly enters between the two guide folds 51. When it hits the aluminum panel 81, the sand and dust are retained in the trough due to inertia and slide down along the aluminum panel 81 due to gravity.

[0053] Second, moisture-proof mode (such as Figure 12 As shown in 12-2 in the figure), the front and rear bent sections 512 of adjacent guide flaps 51 are more tightly fitted, and the channels for the outside air and the internal hot air to be discharged are narrower, which is conducive to heat preservation at night. In addition, the front and rear bent sections 512 are curved, fully covering the hydrophilic breathable membrane 82, increasing the adsorption area and improving the moisture retention rate. At the same time, the heating plate 83 is changed to an internal curved flexible film (not shown in the figure, installed inside the front and rear bent sections 512), which fits the curved surface of the bent section 512 and improves the temperature uniformity of the membrane surface.

[0054] In summary, through the curved surface setting of the guide flap 51, on the basis of inheriting the advantages of intelligent temperature control switching and sewage discharge of the first embodiment, multiple advantages of increased protection efficiency, extended structural life and reduced production costs are achieved, which is particularly suitable for desert conditions with alternating strong sandstorms and high humidity.
