Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more specifically, to an intelligent integrated distribution box. Background Technology

[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, and can provide real-time feedback on operating status, significantly improving the efficiency and accuracy of power management. They have become a key component of modern power systems.

[0003] With the rapid development of solar energy, desert areas have become ideal locations for solar energy equipment due to their abundant sunshine. As an essential universal connection device in the power system, the distribution box faces the erosion of the desert's diurnal environmental changes in this environment. As a channel connecting the inside and outside, the heat dissipation vents are subject to sand and dust carrying floating particles intruding into the equipment during the day, while the severe negative temperature difference at night induces condensation and moisture penetration. This compound pollution not only contaminates electrical components, but also causes insulation deterioration, a surge in contact resistance, and the risk of electric arcing, seriously threatening the lifespan of the equipment.

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

[0005] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide an intelligent integrated distribution box, which solves the problem that under the day-night environmental difference of high temperature and dust and low temperature and easy condensation, the heat dissipation vents of the distribution box are affected by dust intrusion during the day and condensation and moisture penetration induced by negative temperature difference at night, which leads to electrical component contamination, insulation deterioration, surge in contact resistance and risk of electric arc, and thus threatens the life of the equipment.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent integrated distribution box, comprising a cabinet, a heat dissipation vent on the side wall of the cabinet, and a protective box covering the outside of the heat dissipation vent, wherein a heat dissipation unit is provided at the heat dissipation vent; a dustproof and wet protection component is installed inside the protective box, and the dustproof and wet protection component is connected to a drive component installed on the top wall of the protective box; the dustproof and wet protection component includes: multiple guide vanes arranged at equal intervals inside the protective box and a central shaft fixed to the guide vanes and connected to the drive component; the bottom of the protective box is connected to a sludge collection and drainage hopper for discharging sand and condensate falling from the guide vanes; the guide vanes have two working states: when the external temperature is higher than a set threshold, the guide vanes remain in the unfolded state, with the central inclined surface blocking sand and guiding it to slide down; when the external temperature is lower than the set threshold, the guide vanes deflect in the same direction, with the bent surfaces at both ends forming a double water-blocking barrier to prevent moisture from entering the heat dissipation vent.

[0007] In a new embodiment, the guide vane is provided with auxiliary components for sand blocking and dehumidification. The auxiliary components include an aluminum panel and a hydrophilic breathable membrane. The guide vane includes a central angled section and front and rear bent sections. An aluminum panel is installed on the windward side of the angled section. Multiple intercepting columns are equidistantly installed on the wall surface of the aluminum panel. Both the aluminum panel and the intercepting columns are provided with a hydrophobic membrane. The airflow containing sand and dust is intercepted by impacting the gap between adjacent intercepting columns and slides down along the surface of the hydrophobic membrane. The same side wall surface of the front and rear bent sections is attached with a hydrophilic breathable membrane. A heating plate is also embedded in the bent section, and the heating plate is in thermal contact with the hydrophilic breathable membrane. The humid airflow passes through the front and rear hydrophilic breathable membranes twice to intercept moisture, while the heating plate maintains the membrane surface temperature.

[0008] In a new embodiment, the drive assembly includes: a worm gear, fixedly mounted on the top of the central shaft; a worm segment, horizontally disposed on one side of the worm gear and meshing with the corresponding worm gear; and a connecting rod, rotatably mounted on the top of the protective box, on which multiple worm segments are fixedly mounted at equal intervals, and one end of the connecting rod is fixedly connected to the output end of the drive motor located on 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 drive assembly. The temperature control component includes a temperature detector and a microcontroller. The top of the protective box is equipped with an inclined outer shell cover. 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 a set threshold and outputs a control signal to the drive motor to switch the working state of the guide vanes.

[0010] In a new embodiment, an arc-shaped filter plate is installed on the outside of the air inlet of the protective box, and the mesh surface of the arc-shaped filter plate has a continuously undulating wave-like structure.

[0011] In a new embodiment, the bottom surface of the protective box has two discharge ports with its central axis as the axis of symmetry, and the discharge ports are connected to the inlet of the sewage collection and drainage hopper.

[0012] In a new embodiment, a sealing plate is rotatably installed on the side wall of the sewage collection and drainage hopper. The top contact surface of the sealing plate is coated with polytetrafluoroethylene, and a rubber sealing strip is embedded in its top edge. 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 collection and drainage hopper.

[0013] In a new embodiment, the heat dissipation unit uses a mounting bracket, a cooling fan, and a filter to guide and dissipate heat inside the cabinet, and a sealed cabinet door is installed at the front of the cabinet.

[0014] Beneficial effects: Compared with the prior art, the advantages of this invention are as follows: 1. This application addresses the significant differences between day and night environments in desert areas, where there is high temperature and sand and dust during the day and low temperature and easy condensation at night. It provides a dynamic day and night protection mechanism for the heat dissipation vents of the distribution box, achieving precise adaptation between sand and dust protection during the day and moisture blocking at night. This avoids contamination of electrical components, reduces insulation degradation, contact resistance surges and arc risks, and extends equipment life. It not only fully leverages 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 installing a protective box outside the heat dissipation vent of the distribution box, combined with the internal airflow guide vanes, integrated moisture and dust prevention is achieved. The temperature detector on the slanted outer shell of the protective box monitors the external ambient temperature in real time. The microcontroller compares and analyzes the real-time temperature with the preset high and low temperature thresholds, and automatically controls the airflow guide vanes to switch working states. This allows the airflow guide vanes to switch to anti-dust or anti-moisture mode according to changes in external temperature, realizing intelligent and automated adjustment of the protection mode.

[0016] 3. When the external temperature is higher than the set threshold (anti-dust mode), the dust-laden airflow first passes through the arc-shaped filter plate at the air inlet of the protective box. Its wavy mesh surface can initially filter large dust particles. After the remaining airflow enters the protective box, it will collide with the aluminum panel on the windward side of the inclined section of the guide vane. Multiple intercepting columns on the aluminum panel form a strip-shaped grid barrier to further intercept small and medium-sized dust particles. At the same time, the hydrophobic film on the surface of the aluminum panel and the intercepting columns can effectively reduce dust adhesion. Under the action of gravity and airflow impact, the intercepted dust slides down the inclined surface of the inclined section and is discharged into the dust collection hopper through the discharge port at the bottom of the protective box, improving the efficiency of dust interception and discharge.

[0017] 4. When the external temperature is lower than the set threshold (moisture-proof mode), the humid airflow enters the protective box and first comes into contact with the hydrophilic and breathable membrane on the surface of the front bending section. The membrane adsorbs water vapor due to its hydrophilic properties, while retaining a small amount of air circulation space. The trace amount of moisture that is not intercepted by the front membrane will be intercepted again by the hydrophilic and breathable membrane of the rear bending section, forming a double-step water barrier, which greatly reduces the risk of moisture intrusion. In addition, the heating plate embedded in the bending section makes thermal contact with the hydrophilic and breathable membrane after being powered on, so that the membrane surface temperature is always higher than the external environment, effectively preventing the membrane surface from condensing due to low temperature. The intercepted water vapor condenses into liquid water on the membrane surface and slides down the inclined surface of the bending section under the action of gravity, and finally enters the sewage collection and drainage hopper through the discharge port to achieve the discharge treatment of condensate.

[0018] 5. The sewage collection and drainage hopper is driven by a hydraulic rod to rotate the sealing plate, which can open and discharge materials as needed. It is especially suitable for remote desert areas and can significantly reduce the frequency of manual maintenance. The coordinated operation of the discharge port and the sewage collection and drainage hopper forms a closed-loop treatment process of collection, temporary storage and discharge. It can promptly remove sand and dust and condensate intercepted by the guide folds, avoid the long-term accumulation of dirt in the protective box and cause reverse pollution, and ensure the continuous and stable operation of the protection system.

[0040] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] This application provides an intelligent integrated distribution box that solves the problem of electrical component contamination, insulation degradation, increased contact resistance, and arcing risks caused by dust intrusion during the day and condensation at night due to negative temperature differences between day and night, which threaten the lifespan of the equipment. The solution addresses these issues by providing a dynamic day-night protection mechanism for the distribution box's heat dissipation vents.

[0042] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0043] Example 1, please refer to Figures 1-11This application provides an intelligent integrated power distribution box, including 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. A heat dissipation unit 4 is provided at the heat dissipation vent 2. A dustproof and wet protection component 5 is installed inside the protective box 3, and the dustproof and wet protection component 5 is connected to a drive component 6 installed on the top wall of the protective box 3. The dustproof and wet protection component 5 includes: multiple guide vanes 51 arranged at equal intervals inside the protective box 3 and a central shaft 52 fixed to the guide vanes 51 and connected to the drive component 6. The bottom of the protective box 3 is connected to a sludge collection and drainage hopper 7 for draining sand and condensate falling from the guide vanes 51. The guide vanes 51 have two working states: when the external temperature is higher than a set threshold, the guide vanes 51 remain in the unfolded state, and the middle inclined surface blocks the sand and guides it to slide down; when the external temperature is lower than the set threshold, the guide vanes 51 deflect in the same direction, and the bent surfaces at both ends form a double water barrier to prevent moisture from entering the heat dissipation vent 2.

[0044] Furthermore, the heat dissipation unit 4 uses a combination of mounting bracket, cooling fan and filter to guide and dissipate heat inside the cabinet 1. The front of the cabinet 1 is equipped with a sealed cabinet door.

[0045] The preferred implementation of this solution addresses the differences in desert day and night environments, where high temperatures and sandstorms occur during the day and low temperatures and condensation occur at night. The heat dissipation vent 2 of the distribution box is equipped with a protective box 3, which can automatically switch the working mode and protective effect according to the external temperature. This achieves dynamic adaptation between sandstorm protection during the day and moisture blocking at night, demonstrating the intelligent unmanned management of the distribution box, improving operational efficiency, and showcasing the comprehensive adaptability of the distribution box to different external environments.

[0046] The specific dust and moisture prevention procedures for the distribution box are as follows:

[0047] First, the temperature detector 91 on the slanted outer shell at the top 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 (such as a high temperature threshold of 30°C and a low temperature threshold of 15°C). By comparing the real-time temperature with the threshold, it outputs a control signal to the drive component 6, thereby determining the working position of the guide vane 51.

[0048] Second, the microcontroller 92 controls the start of the drive motor, which drives the worm section 62 on the connecting rod 63 to rotate. The worm section 62 meshes with the worm wheel 61, thereby driving the central shaft 52 to rotate, causing all the guide vanes 51 fixed to the central shaft 52 to rotate, thereby allowing the guide vanes 51 to switch between two modes: anti-dust mode and anti-moisture mode.

[0049] Anti-dust mode: When the external temperature exceeds the set threshold, the external airflow containing dust first passes through the curved filter plate 10 at the air inlet of the protective box 3. The wavy mesh surface initially filters out large dust particles. The remaining airflow enters the protective box 3 and impacts the aluminum panel 81 on the windward side of the inclined section 511 of the guide vane 51. Multiple intercepting columns 811 installed on the aluminum panel 81 form a strip-shaped barrier, further intercepting small and medium-sized dust particles. At the same time, the hydrophobic film 812 on the surface of the aluminum panel 81 and the intercepting columns 811... To reduce sand and dust adhesion, the trapped sand and dust slide down the inclined surface of the inclined section 511 under the impact of gravity and airflow. The sliding sand and dust enter the sewage collection and drainage hopper 7 through the discharge port 31 at the bottom of the protective box 3, and temporarily accumulate on the sealing plate 71 on the sewage collection and drainage hopper 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 the sealing when closed). The sand and dust are discharged to the outside along the inclined surface of the sealing plate 71.

[0050] Moisture-proof mode: When the external temperature is lower than the set threshold, the microcontroller 92 controls the drive motor to rotate in the opposite direction, which drives the central shaft 52 to rotate through the drive assembly 6, causing all the guide vanes 51 to deflect in the same direction (the front and rear bending sections 512 retract inward to form a relatively closed barrier), thus switching to the moisture-proof mode.

[0051] When external humid airflow (moisture formed by condensation overnight) enters the protective box 3, it first comes into contact with the hydrophilic and breathable membrane 82 on the surface of the front bending section 512. The membrane adsorbs moisture through its hydrophilic properties while allowing a small amount of airflow (to avoid heat dissipation failure due to complete sealing). The trace amount of moisture that is not intercepted by the front membrane is intercepted again by the hydrophilic and breathable membrane 82 of the rear bending section 512, forming a double-step water barrier. At the same time, the heating plate 83 embedded in the bending section 512 is energized and heats up (which interacts with the hydrophilic and breathable membrane 82). (The thermally conductive contact) ensures that the membrane surface temperature is always higher than the external environment, preventing condensation on the membrane surface due to low temperature (condensation will block the membrane pores and reduce air permeability and moisture barrier capacity). The intercepted water vapor condenses into liquid water on the membrane surface and slides down the inclined surface of the bending section 512 under gravity. The condensate also enters the sewage collection and drainage hopper 7 through the discharge port 31 and is temporarily stored on the sealing plate 71. When cleaning is required, the hydraulic rod 74 pushes the sealing plate 71 to open, and the condensate is discharged to the outside along the inclined surface of the sealing plate 71, preventing water accumulation in the protective box 3 from breeding mold.

[0052] It should be noted that even in the moisture-proof mode, trace amounts of dust-laden airflow may still seep in through the narrow channels between the bending sections 512, causing sand and dust to be passively trapped on the surface of the hydrophilic and breathable membrane 82. If the residual sand and dust mix with condensate, there is a risk of caking 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 temperature, accelerating the condensation and sliding of water vapor, minimizing the sand-water contact time. The transitional mixture of sliding sand and condensate (which will not be trapped on the surface of the sealing plate 71, as the sealing plate 71 has a polytetrafluoroethylene coating 72 with superhydrophobic and oleophobic properties, preventing the mixture from wetting the plate surface and thus not remaining on the sealing plate 71) flows into the sludge collection hopper 7 through the discharge port 31 at the bottom of the protective box 3. During mode switching or periodic sludge removal, the sealing plate 71 is forcibly opened by the hydraulic rod 74 to completely discharge the sludge to the outside, eliminating the risk of membrane pore blockage.

[0053] Third, the heat generated inside the cabinet 1 is guided to the heat dissipation vent 2 through the heat dissipation unit 4 (mainly a cooling fan). In the dustproof mode or when the airflow guide fins 51 are in the deployed state, hot air passes directly through the gaps between the airflow guide fins 51 and is smoothly discharged from the protective box 3. In the moisture-proof mode, the inwardly contracting bending section 512 creates a tortuous channel between adjacent airflow guide fins 51, which obstructs the flow of hot air: on the one hand, it slows down the rate of heat loss and plays a certain role in heat preservation at night; on the other hand, the moderately restricted hot air accumulates in the area of ​​the heat dissipation vent 2, forming a stable heat flow layer, which helps to block the intrusion of cold and humid external air.

[0054] In summary, this distribution box intelligently switches the working mode of the dustproof and wet component 5 through the temperature control component 9, and is supplemented by the arc filter plate 10, the sewage collection and drainage hopper 7 and the drive component 6, to accurately adapt to the desert day and night environment: it can efficiently prevent dust and discharge sewage when it is hot and dry, and strictly prevent moisture and dehumidify and prevent condensation when it is cold and humid. At the same time, the heat dissipation unit 4 ensures continuous heat dissipation of the cabinet 1.

[0055] Please see Figures 6-10 As shown, the guide vane 51 is provided with auxiliary components 8 for sand blocking and dehumidification. The auxiliary components 8 include an aluminum panel 81 and a hydrophilic and breathable membrane 82. The guide vane 51 includes a beveled section 511 in the middle and bent sections 512 at the front and rear. An aluminum panel 81 is installed on the windward side of the beveled section 511. Multiple intercepting columns 811 are equidistantly installed on the wall surface of the aluminum panel 81. Both the aluminum panel 81 and the intercepting columns 811 are provided with hydrophobic materials. Membrane 812: When the airflow containing sand and dust impacts the gap between the adjacent intercepting columns 811, it is intercepted and slides down the surface of the hydrophobic membrane 812. Hydrophilic and breathable membranes 82 are attached to the same side wall of the front and rear bending sections 512. A heating plate 83 is also embedded in the bending section 512, and the heating plate 83 is in thermal contact with the hydrophilic and breathable membrane 82. The humid airflow passes through the front and rear hydrophilic and breathable membranes 82 twice to intercept moisture. At the same time, the heating plate 83 maintains the membrane surface temperature.

[0056] In the preferred embodiment of this solution, under the sand and dust prevention function, when the sand and dust-laden airflow impacts the aluminum panel 81 on the windward side of the angled section 511, the intercepting columns 811 arranged at equal intervals on the surface of the aluminum panel 81 form a physical grid barrier. The sand and dust particles are intercepted by the gaps between adjacent intercepting columns 811 due to inertial impact. The hydrophobic film 812 on the surface of the aluminum panel 81 and the intercepting columns 811 reduces the adhesion of sand and dust, allowing the sand and dust to slide off the slope under the impact of gravity and airflow, thus achieving self-cleaning.

[0057] Under the moisture-proof function, the humid airflow passes sequentially through the hydrophilic and breathable membranes 82 on the walls of the front and rear bending sections 512. The front hydrophilic and breathable membrane 82 adsorbs some water vapor, allowing a small amount of air to circulate (ensuring basic heat dissipation), forming the first layer of interception. The rear hydrophilic and breathable membrane 82 traps residual moisture, forming a double moisture barrier, forming the second layer of interception. The heating plate 83 is embedded inside the bending section 512 and makes thermal contact with the hydrophilic and breathable membrane 82, maintaining the membrane surface temperature higher than the ambient temperature and preventing the membrane surface from condensing and clogging the micropores due to low temperature (ensuring breathability). The adsorbed water vapor condenses into liquid water on the membrane surface and slides down the slope due to gravity and is discharged.

[0058] Please see Figure 4 and Figure 5 As shown, the drive assembly 6 includes: a worm gear 61, which is fixedly installed on the top of the central shaft 52; a worm segment 62, which is horizontally arranged on one side of the worm gear 61 and meshes with the corresponding worm gear 61; and a connecting rod 63, which is rotatably installed on the top of the protective box 3. Multiple worm segments 62 are fixedly installed 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 drive motor located on the top of the protective box 3.

[0059] In the preferred embodiment of this solution, after the drive motor (located on top of the protective box 3) is started, its output end drives the connecting rod 63 to rotate synchronously. Multiple worm gear segments 62, which are fixedly installed at equal intervals on the connecting rod 63, rotate coaxially with the connecting rod 63. Each worm gear segment 62 meshes with the worm wheel 61 on the top of the corresponding guide vane 51. The rotational motion of the worm gear segment 62 is transmitted to the worm wheel 61 through meshing. The worm wheel 61 then drives the central shaft 52 to rotate synchronously. All guide vanes 51 are rigidly linked through the central shaft 52. The rotation of the central shaft 52 drives all guide vanes 51 to deflect synchronously, realizing the switching between the sand and dust prevention mode (expanded) and the moisture prevention mode (folded).

[0060] Please see Figure 4As shown, the protective box 3 is equipped with a temperature control component 9 that provides a trigger signal for the drive assembly 6. The temperature control component 9 includes a temperature detector 91 and a microcontroller 92. The top of the protective box 3 is equipped with an inclined outer cover. The temperature detector 91 is installed on the inclined outer cover, and the microcontroller 92 is installed on the bottom wall of the inclined outer cover. The temperature detector 91 and the microcontroller 92 are electrically connected. The microcontroller 92 compares the temperature with a set threshold and outputs a control signal to the drive motor to switch the working state of the guide vane 51.

[0061] In the preferred embodiment of this solution, the temperature detector 91 installed on the top of the inclined outer shell is directly exposed to the external environment, eliminating the interference of the box structure on temperature measurement, and collecting high-precision temperature data in real time. The microcontroller 92 judges the working conditions through dual threshold (high temperature / low temperature) logic (such as starting the anti-sand dust mode when the temperature is greater than 30℃ and starting the anti-moisture mode when the temperature is less than 15℃), realizing the adaptive switching of the desert day and night environment without manual intervention. The microcontroller 92 directly outputs control signals to the drive motor, which links all the guide vanes 51 to deflect synchronously through the drive assembly 6 (worm gear 61, worm section 62 and connecting rod 63).

[0062] Meanwhile, to prevent sand / rainwater from accumulating on the surface of the temperature detector 91 and ensure long-term monitoring accuracy, the microcontroller 92 is built into the bottom wall of the cover, physically isolating it from external damp heat / sand erosion, extending circuit life, and supporting custom temperature thresholds according to different desert climates (such as the high temperature threshold can be adjusted to 35℃), thus improving regional adaptability.

[0063] Please see Figure 4 As shown, an arc-shaped filter plate 10 is installed on the outside of the air inlet of the protective box 3. The mesh surface of the arc-shaped filter plate 10 has a continuous undulating wave-like structure.

[0064] In the preferred embodiment of this solution, the wavy mesh surface of the arc-shaped filter plate 10 forms a continuously undulating curved channel. When the airflow containing sand and dust passes through, large sand and dust particles are directly intercepted due to inertial impact on the concave surface of the trough. At the same time, the tortuous airflow path also prolongs the residence time of sand and dust on the surface of the arc-shaped filter plate 10, improving the interception efficiency. The non-planar structure avoids the uniform accumulation of sand and dust on the filter screen surface, significantly reducing the risk of blockage of the arc-shaped filter plate 10. After the sand and dust impact the concave surface of the trough, it naturally slides down the curved surface to the bottom of the arc-shaped filter plate 10 under the action of gravity (it is not easy to adhere to the non-horizontal surface). When the external airflow impacts the convex surface of the wave crest, it generates local turbulence, which helps to shake off the attached sand and dust, reducing the frequency of manual cleaning.

[0065] Please see Figure 11 As shown, the bottom surface of the protective box 3 has two discharge ports 31 with its central axis as the axis of symmetry. The discharge ports 31 are connected to the inlet of the sewage collection and drainage hopper 7.

[0066] Furthermore, please refer to Figure 11As shown, a sealing plate 71 is rotatably installed on the side wall of the sewage collection and drainage hopper 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 its top edge. The bottom of the sealing plate 71 is rotatably connected to the rod of the hydraulic rod 74, and the cylinder of the hydraulic rod 74 is rotatably installed on the side wall of the sewage collection and drainage hopper 7.

[0067] In the preferred embodiment of this solution, the sealing plate 71 is driven to rotate by the hydraulic rod 74, which enables the collection and drainage hopper 7 to be opened on demand (i.e., it is started to discharge once after each mode of sand or condensate collection is completed). This avoids the back intrusion of external sand and dust due to the long-term openness of the traditional fixed open discharge port 31. It is especially 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 collection and drainage hopper 7 when closed. With the polytetrafluoroethylene coating 72 on the contact surface, the sealing performance is guaranteed (preventing moisture from flowing back from the discharge port 31 to the protective box 3 at night). The cooperation between the discharge port 31 and the collection and drainage hopper 7 allows the sand and dust intercepted by the guide baffle 51 to be treated through a closed-loop process of collection, temporary storage and discharge, avoiding the back pollution problem caused by the long-term accumulation of dirt in the protective box 3.

[0068] Example 2: Based on Example 1, the overall structure of the guide vane 51 is optimized into a continuous curved surface (e.g., Figure 12 As shown), while retaining the functional partitions of the angled segment 511 and the bending segment 512, the structure is integrated through curved surface transition. The specific workflow is as follows:

[0069] First, the sandstorm protection mode (such as...) Figure 12 As shown in Figure 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 canceled). Its surface is equidistantly embedded with intercepting bars 811 and fully covered with a hydrophobic film 812 (omitted in the figure). When the airflow is guided by the front bending section 512 and directly enters between the two guide folds 51, it impacts the aluminum panel 81. Due to inertia, the sand and dust are trapped in the trough and slide down the aluminum panel 81 under gravity.

[0070] Second, moisture-proof mode (such as) Figure 12 As shown in Figure 12-2, the front and rear bending sections 512 of the adjacent guide flaps 51 are more closely attached, and the channels for external air and internal heat exhaust are narrower, which is beneficial for heat preservation at night. In addition, the front and rear bending sections 512 are curved and fully cover the hydrophilic and 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 bending sections 512), which fits the curved surface of the bending section 512, improving the uniformity of membrane surface temperature.

[0071] In summary, by using the curved surface design of the guide vane 51, the system achieves multiple advantages, including enhanced protective performance, extended structural lifespan, and reduced production costs, while inheriting the advantages of intelligent temperature control switching and sewage discharge from the first embodiment. It is particularly suitable for desert conditions characterized by alternating strong sandstorms and high humidity.
