Description

Technical Field

[0001] This application relates to the field of industrial-grade power supply waterproofing technology, and in particular to an industrial-grade power supply with waterproof components and its waterproof control system. Background Technology

[0002] With the rapid development of industrial automation and intelligent manufacturing, the requirements for the reliability and stability of power supply systems are becoming increasingly stringent. Especially in harsh industrial environments, such as high humidity, dust, and susceptibility to water splashes, the waterproof and dustproof performance of power supply systems is of paramount importance.

[0003] Currently, waterproofing technology for industrial power supplies is relatively advanced. Industrial power supplies meeting the highest IP protection level can operate normally even after being submerged in water exceeding one meter in depth. However, to achieve high waterproofing standards, most industrial power supplies employ special materials and sealing technologies, and the production of their waterproof casings utilizes a unibody manufacturing process. This requires high costs and large production lines, making it an unwise choice for cost-sensitive applications and manufacturers.

[0004] Furthermore, current waterproofing technologies largely rely on improvements in waterproofing materials, with structural improvements limited to creating sealed structures to enhance sealing performance. For most industrial power supplies, this sealed structure essentially closes off heat dissipation vents, which negatively impacts heat dissipation, leading to increased internal temperatures under high loads and affecting performance and lifespan.

[0005] Regarding the aforementioned technologies, existing waterproof structures for industrial power supplies can be improved from the perspective of low structural cost, taking into account both heat dissipation and waterproof performance of industrial power supplies. Summary of the Invention

[0006] To improve the heat dissipation and waterproofing performance of industrial power supplies, this application provides an industrial-grade power supply with waterproof components and its waterproof control system.

[0007] On the one hand, the industrial-grade power supply with waterproof components provided in this application adopts the following technical solution: An industrial-grade power supply with waterproof components includes a housing, inside which a core power component is housed, and further includes: A drainage chamber is located at the bottom of the housing. External heat dissipation holes are provided on the side wall of the drainage chamber, connecting the inner and outer spaces of the drainage chamber. Internal heat dissipation holes are provided on the top wall of the drainage chamber, connecting the space where the core power components are located. A scraping plate is disposed at the bottom of the two opposite side walls of the drainage chamber. A driving component is provided on the side wall of the drainage chamber to drive the scraping plate to slide. The bottom edge of the scraping plate abuts against the bottom wall of the drainage chamber. A sealing component is disposed inside the side wall of the drainage chamber, corresponding to the external heat dissipation hole, and is used to seal the external heat dissipation hole; A cooling component is installed on the inner wall of the drainage chamber to reduce the internal temperature of the drainage chamber.

[0008] By adopting the above technical solution, the housing is a shell structure that protects the core power components inside the industrial-grade power supply. A drainage chamber is set at the bottom of the housing, and waterproof and drainage components are installed in the drainage chamber to protect the core power components inside the housing. Under normal circumstances, the heat generated by the core power components is discharged into the drainage chamber through the inner heat dissipation holes, and then discharged through the outer heat dissipation holes of the drainage chamber. Therefore, a drainage chamber separates the core power components from the external environment of the housing, and the area where the core power components are located is directly connected to the external environment through the inner and outer heat dissipation holes. When the power supply is in a humid environment, the sealing component blocks the external heat dissipation holes, blocks the direct connection between the drainage chamber and the outside world, and prevents the moisture from the outside world from entering the drainage chamber, thus protecting the core power components inside the casing. The operation of the sealing component blocks the connection between the drainage chamber and the outside world, which affects the heat dissipation effect of the industrial-grade power supply. The cooling component lowers the temperature inside the drainage chamber to compensate for the reduced heat dissipation effect. When a sudden severe power supply condition causes external water to enter the drainage chamber through the external heat dissipation holes, the sealing component should be activated in advance to seal the drainage chamber. To prevent water from accumulating in the drainage chamber and causing it to become damp, the drive component inside the drainage chamber should be activated to drive the scraper to slide along the bottom wall of the drainage chamber and scrape off the water at the bottom of the drainage chamber. The scraped water will then flow out through the external heat dissipation holes. Furthermore, in all cases described above, the cooling components should be activated while the drainage chamber is sealed to ensure the heat dissipation of the industrial-grade power supply.

[0009] Optionally, the drainage chamber has an inner groove inside the chamber wall on the side corresponding to the external heat dissipation hole, and the sealing component is disposed in the inner groove; The enclosed component includes: A sealing block is horizontally positioned and vertically slidable within the inner groove, the length of which is greater than the length of the outer heat dissipation hole; A sealing membrane connects the sealing block to the bottom wall of the inner groove. As the sealing block slides, the sealing membrane seals the external heat dissipation hole.

[0010] By adopting the above technical solution, the sealing component needs to seal the external heat dissipation holes. Therefore, it is necessary to set up a space for installing the sealing component inside the drainage chamber, or to save the internal space of the drainage chamber, a groove for accommodating the sealing component can be opened inside the side wall of the drainage chamber corresponding to the sealing component. Even if the side wall of the drainage chamber is set as a double layer, the sealing component is placed inside the inner groove. Under normal conditions, the sealing block is located below the external heat dissipation hole, and the sealing membrane is piled up in the inner tank. The space between the sealing block and the bottom wall of the inner tank does not block the external heat dissipation hole, ensuring the opening area of ​​the external heat dissipation hole. When it is necessary to close the drainage chamber, the sealing block slides upward, and the sealing membrane unfolds until the sealing block slides above the external heat dissipation hole, so that the sealing membrane fully covers the external heat dissipation hole and closes it. On this basis, the length of the sealing block should be equal to the length of the inner tank and the sealing membrane to reduce the amount of moisture or water entering the drainage chamber. A small amount of liquid that enters the drainage chamber through the sealing membrane and the edge of the inner tank will be discharged from the drainage chamber after the sealing block and the sealing membrane are no longer sealing the drainage chamber or through other structures. The waterproof membrane in the above scheme is made of waterproof fabric.

[0011] Optionally, the top edge of the sealing block is flush with the bottom edge of the external heat dissipation hole.

[0012] By adopting the above technical solution, under normal conditions, when the external heat dissipation hole is not closed, the top side of the sealing block is flush with the edge of the external heat dissipation hole, which can seal the part of the inner tank below the external heat dissipation hole, thus preventing the space below the external heat dissipation hole from causing water to flow in and accumulate in the inner tank in case of an emergency. In addition, the external heat dissipation holes serve as heat dissipation holes for the power supply. When the power supply is working normally, hot air is discharged. If there is a gap between the top surface of the sealing block and the bottom surface of the external heat dissipation hole, dust and impurities in the air will accumulate in the gap between the bottom surface of the external heat dissipation hole and the top surface of the sealing block when the hot air is discharged, causing dust accumulation.

[0013] Optional, also includes: A drainage hole is provided in the drainage chamber on one side wall of the external heat dissipation hole and below the external heat dissipation hole, connecting the drainage chamber to the outside of the shell; The drainage plate has its top edge hinged to the top wall of the drainage hole, and its bottom edge is free. The drainage plate is provided with multiple permanent magnets corresponding to the wall of the drainage hole, so that the drainage plate is in contact with the bottom edge.

[0014] By adopting the above technical solution, considering structural issues, there is a certain height difference between the bottom edge of the external heat dissipation vent and the bottom of the casing. Therefore, when the water accumulation at the bottom of the drainage chamber is small, the water cannot be drained from the bottom of the drainage chamber in time. Therefore, drainage holes are opened in the drainage chamber wall below the external heat dissipation vent, allowing the water scraped by the scraper to flow out through the drainage holes in time, preventing accumulation in the drainage chamber. To close the drainage holes during normal operation of the industrial power supply without interfering with water flow, a drainage plate is hinged to the top edge of the drainage hole wall in the above solution. The size of the drainage plate fits the size of the drainage hole. Under normal operation of the industrial power supply, the side wall edge of the drainage hole fits the edge side wall of the drainage hole, keeping the drainage plate vertical, serving as one of the side walls of the drainage chamber. When the industrial power supply is in normal operation, i.e., the drainage plate is vertical, the edge of the drainage plate is magnetically fixed, ensuring stable fixation. The magnetic fixing method involves setting permanent magnets at the joints between the drainage plate surface and the drainage hole wall edge. The permanent magnets at the drainage hole wall edge attract the permanent magnets on the drainage plate, fixing it in place. When it is necessary to drain the water in the drain chamber, the drive mechanism of the scraper bar drives the scraper bar to slide towards the drain hole, and the drain plate rotates around the hinge side to discharge the water from the inside of the drain chamber.

[0015] Optionally, a slider is slidably connected to the inner wall of the drainage chamber corresponding to the scraper, the scraper is hinged to the slider, and the slider is provided with a driving component for driving the scraper to rotate.

[0016] By adopting the above technical solution, the sliding method of the scraper in the drainage chamber is restricted and explained. In the above solution, the sliding block is driven by the driving component to slide, which in turn drives the scraper hinged on the sliding block. For this purpose, guide grooves for guidance need to be opened on the inner walls of the two opposite sides of the drainage chamber. The guide groove is opened at one end near the drainage hole to prevent water from accumulating in the guide groove. The driving component drives the sliding block to slide along the guide groove toward the drainage hole. At the same time, the scraper abuts against the bottom wall of the drainage chamber, and the accumulated water on the bottom wall of the drainage chamber flows out from the drainage hole. Furthermore, the hinged connection between the scraper and the slider in the above solution enables the scraper to achieve a scraping effect similar to a "car windshield wiper," improving cleaning ability. More importantly, when the scraper slides to a position close to the drain plate, the rotation of the scraper can push the magnetically fixed drain plate to open the drain hole, eliminating the need for additional components specifically designed to open the drain hole.

[0017] Optionally, the bottom wall of the drainage chamber is inclined downward along the direction close to the drainage hole, and the side of the drainage chamber away from the external heat dissipation hole is higher than the bottom edge of the external heat dissipation hole.

[0018] By adopting the above technical solution, the bottom wall of the drainage chamber is inclined towards the drain hole, so that the water accumulated in the drainage chamber flows towards the drain hole under the action of gravity, thereby improving the ability to remove water accumulated in the drainage chamber; in order to adapt to the inclined bottom wall of the drainage chamber, the above-mentioned chute in the drainage chamber should be parallel to the inclined bottom wall surface of the drainage chamber, and the above-mentioned scraper should slide and rotate perpendicular to the inclined bottom wall surface of the drainage chamber. Based on this, the higher edge of the inclined bottom wall of the drainage chamber is higher than the bottom edge of the external heat dissipation hole. When water flows in from the external heat dissipation hole and accumulates in the drainage chamber, it can be ensured that a part of the bottom wall of the drainage chamber is exposed above the water surface. That is, the premise for external water to flow into the drainage chamber from the external heat dissipation hole is that the liquid level of the water in the external environment must be higher than the liquid level of the bottom edge of the external heat dissipation hole. Therefore, when the sealing component cannot operate effectively in time, after the drainage chamber is submerged, the liquid level in the drainage chamber is level with the liquid level of the external environment and higher than the bottom edge of the external heat dissipation hole. Therefore, in the above scheme, under normal operation of the industrial power supply, the initial state of the scraper is set at the higher edge of the inclined bottom wall of the drainage chamber to protect the scraper after the drainage chamber is submerged.

[0019] Optionally, the cooling component includes: A cold water tank is formed on the side of the shell near the drain compartment and is filled with cold water. A cold water tank is located inside the multiple side walls of the drainage compartment and is connected to the cold water tank. A heat exchange plate is disposed on the inner wall of multiple sides of the drainage chamber, and the portion of the heat exchange plate corresponding to the cold water tank is made of a heat-sensitive material.

[0020] By adopting the above technical solution, the cooling component is used to reduce the temperature of the drainage chamber after it is sealed, thus ensuring the cooling effect of the core power components. The main cooling structure consists of a cold water tank and a cold water bath. The cold water tank is directly connected to the water source through water pipes. Compared with traditional technical solutions, the additional water pipe structure connects to the water source, replacing the dedicated air-cooled or liquid-cooled components in a sealed state, which greatly reduces the structural cost. The power for water flow between the cold water tank and the water source is achieved by a water pump. After the drainage chamber is closed, the cooling components operate. The water pump draws cold water from the water source to the cold water tank. The cold water in the cold water tank is drawn from the water source into the cold water tank and then transported from the cold water tank to the cold water trough. Heat exchange is carried out by heat exchange plates made of heat-sensitive materials. The water in the cold water trough absorbs heat from the air in the drainage chamber, reducing the air temperature in the drainage chamber. During the heat exchange process, the cold water in the cold water tank and the cold water trough keeps flowing. The water circulation between the cold water tank and the cold water trough is driven by the water pump in the cold water tank. It should be noted that in the above scheme, the cold water tank and the inner tank must be separated, and the two tanks are independent and not connected.

[0021] Optionally, a door is provided on one side of the housing to open the internal space of the housing, and a sealing strip is provided on the housing corresponding to the edge of the door, the sealing strip being made of waterproof material.

[0022] By adopting the above technical solution, the hatch of the shell is used by technicians to open the shell and inspect the core electrical components inside. The hatch provides a channel for the inside of the shell to connect with the outside. When the power supply is operating normally, the hatch is closed, but there is still a risk of water ingress at the edge of the hatch. Therefore, waterproof sealing structures such as waterproof strips and rubber are attached to the edge of the hatch to prevent water vapor from corroding the inside of the shell in a humid environment.

[0023] On the one hand, the control system of an industrial-grade power supply with waterproof components provided in this application adopts the following technical solution: A control system for an industrial-grade power supply with waterproof components includes a central control module, a monitoring module, a display module, and a control module; The monitoring module is installed inside the drainage chamber and on the outer surface of the shell. It is used to monitor the ambient humidity and the humidity inside the drainage chamber, and upload the collected data to the central control module. When the shell is submerged in water, the monitoring module measures the water level of the shell and uploads the collected water level data to the central control module. The control module receives instructions from the central control module and controls the operation of the scraper, sealing component, and cooling component according to the instruction information; The central control module receives the collected data uploaded by the monitoring module, calculates and analyzes the environmental state of the industrial power supply, generates corresponding instruction information based on the calculation and analysis results, and controls the control module to take corresponding waterproof measures in different environments of the industrial power supply according to the corresponding instructions. The display module is connected to the central control module and displays the calculation and analysis results of the central control module, as well as the real-time surrounding environment of the industrial-grade power supply, so that the control personnel can obtain the operating status of the industrial-grade power supply waterproof system in a timely manner.

[0024] By adopting the above technical solution, the monitoring module is the front-end monitoring component of the system. It monitors the ambient humidity, the water level in the casing, the air humidity in the drainage chamber, and the water level in the drainage chamber in real time. It uploads the collected information related to humidity and water level to the central control system. The central control system processes the collected information and determines whether waterproofing measures need to be activated based on the current ambient humidity and the water level in the casing. The central control system prioritizes the processing of information on the water level inside and outside the power supply over the ambient humidity. When the monitoring module detects water levels inside and outside the power supply, the ambient humidity data is no longer used as the basis for determining whether the waterproofing components need to be activated. After processing the information, the central control module sends corresponding control commands to the control component to control the operation of the cooling component and the sealing component. The monitoring information of the monitoring module, the operating status of the cooling component and the sealing component, and the operating status of the scraper can all be displayed through the display component. The controller can obtain the operating status of the waterproof system based on the information displayed on the display component. The display module in the above solution can be integrated into the central control component of the industrial power supply.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By adding a drainage chamber, a scraper, a sealing component, and a cooling component, this invention successfully achieves a balance and optimization of both waterproof and heat dissipation performance, ensuring the stable operation of the power supply in harsh environments; 2. The unique design of the enclosed components effectively prevents moisture from entering the power supply through the external heat dissipation holes without affecting heat dissipation performance, greatly improving the power supply's waterproof capability; 3. The use of a scraper can promptly remove impurities that enter the drainage chamber; 4. The cooling component can reduce internal heat during sealed operation of the power supply, thereby avoiding performance degradation or lifespan reduction caused by temperature rise and extending the overall service life of the power supply.

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] This application first discloses an industrial-grade power supply with waterproof components. (Refer to...) Figure 1 and Figure 2 An industrial-grade power supply with waterproof components includes a housing 1 and an equipment compartment 11 inside the housing 1. The equipment compartment 11 houses a core power component, which serves as the core part of the industrial-grade power supply for power storage and conversion. A door is provided on the side of the housing 1 corresponding to the height of the core power component, and a sealing strip 12 is provided on the edge of the door. When the door is closed, the edge of the door is pressed tightly against the sealing strip 12 to prevent moisture from entering the interior of the housing 1 when the door is closed. A drainage compartment 2 is provided below the equipment compartment 11 on the housing 1. The drainage compartment 2 is equipped with a drainage structure that can promptly drain water entering the drainage compartment 2, protecting the core power component in the equipment compartment 11 and preventing the core power component in the equipment compartment 11 from being submerged in water.

[0036] Reference Figure 1 and Figure 2 The top wall of the drainage chamber 2 is provided with an internal heat dissipation hole 22 that connects to the equipment chamber 11, so that the heat generated by the operation of the power core component can be immersed into the drainage chamber 2 through the internal heat dissipation hole 22. An external heat dissipation hole 21 is provided on one side wall of the drainage chamber 2, which connects the drainage chamber 2 to the outside of the shell 1, so that the heat in the drainage chamber 2 can be discharged through the external heat dissipation hole 21. Thus, the heat generated by the power core component is discharged from the equipment chamber 11 to the outside of the shell 1 through the internal heat dissipation hole 22 and the external heat dissipation hole 21 in sequence.

[0037] Reference Figure 2 and Figure 3 A cooling fan 23 for providing airflow is fixedly connected to the inner wall of the drainage chamber 2 on the side opposite to the external heat dissipation hole 21. The cooling fan 23 rotates to increase the airflow speed and improve the efficiency of heat exchange. Reference Figure 2 and Figure 3A drainage hole 24 is provided on the side wall of the drainage chamber 2 below the external heat dissipation hole 21. A drainage plate 241 is hinged to the top of the top wall of the drainage hole 24. The top edge of the drainage plate 241 is hinged to the top wall of the drainage hole 24, and the bottom edge of the drainage plate 241 is the free side. The drainage plate 241 rotates around the top hinged side. When it rotates to a vertical position and fits against the edge of the drainage hole 24, it closes the drainage hole 24. When it rotates to an inclined position, it opens the drainage hole 24. Thus, the surface area of ​​the drainage plate 241 is larger than the opening area of ​​the drainage hole 24, so that when the drainage plate 241 rotates to a vertical position, it can close the drainage hole 24 and prevent water in the drainage chamber 2 from accumulating in the corner of the drainage chamber 2.

[0038] Reference Figure 2 and Figure 3 Since the bottom side of the aforementioned drainage plate 241 is a free end, under normal operation of the industrial power supply, the surface of the drainage plate 241 needs to be pressed against the edge of the drainage hole 24 to seal the drainage hole 24. In this embodiment, a magnetic fixing method is adopted, that is, multiple permanent magnet blocks are set as magnetic attracting components. The multiple permanent magnet blocks are evenly distributed and embedded in the side of the drainage plate 241 near the drainage hole 24, and are embedded in the hole wall of the drainage hole 24 one by one. When the surface of the aforementioned drainage plate 241 is in a vertical state, it is attracted by the two corresponding permanent magnets 242, and the surface of the drainage plate 241 is tightly attached to the hole wall of the drainage hole 24.

[0039] Reference Figure 3 The bottom wall of the drainage chamber 2 is inclined downwards towards the side near the drainage hole 24, so that the water flowing into and accumulating in the drainage chamber 2 will accumulate on one side of the drainage plate 241 under the action of gravity. The drainage chamber 2 has a sliding groove 25 on both sides adjacent to the external heat dissipation hole 21. A slider 251 is slidably connected in the sliding groove 25. The sliding groove 25 is symmetrically distributed on opposite sides along the center of the drainage chamber 2. The length direction of the sliding groove 25 is parallel to the inclined bottom wall of the drainage chamber 2, so that the sliding direction of the slider 251 is parallel to the inclined direction of the bottom wall of the drainage chamber 2. A driving component for driving the slider 251 to slide is provided in the sliding groove 25. In this embodiment, the slider 251 is driven by a screw. Therefore, a rotating motor 252 is provided inside the side of the sliding groove 25 away from the drainage hole 24, and a screw is rotatably connected in the sliding groove 25. The length direction of the screw is parallel to the length direction of the sliding groove 25. The screw passes through and is threadedly connected to the slider 251. The rotating motor 252 drives the screw to rotate, so that the slider 251 slides stably along the sliding groove 25.

[0040] Reference Figure 3Inside the drainage chamber 2, two sliders 251 are hinged to opposite sides with scraping plates 26. The surfaces of the scraping plates 26 are perpendicular to the inclined bottom wall of the drainage chamber 2, and the bottom edges of the scraping plates 26 abut against the inclined bottom wall of the drainage chamber 2. As the sliders 251 slide, the scraping plates 26 scrape away water, impurities, etc., adhering to the bottom wall of the drainage chamber 2. The two scraping plates 26 slide towards the side closer to the drainage hole 24, allowing the scraped impurities to flow out from the drainage hole 24. The two scraping plates 26 are hinged around the sliders 251. As the shaft rotates, the surface of the scraper 26 remains perpendicular to the bottom wall of the drainage chamber 2 during the rotation. When the scraper 26 is driven by the rotating motor 252 to slide downwards and approach the drainage plate 241, both scraper 26 rotate towards the drainage plate 241. The free ends of the scraper 26 abut against the surface of the drainage plate 241 and maintain the rotation trend until the pushing force of the scraper 26 is greater than the magnetic attraction force of the drainage plate 241, causing the drainage plate 241 to tilt, opening the drainage hole 24, and releasing the water accumulated in the drainage chamber 2.

[0041] Considering that the slider 251 and the scraper 26 may be submerged in water, the rotation of the scraper 26 is achieved by a waterproof micro motor 253.

[0042] Reference Figure 3 The bottom wall of the drainage chamber 2 has an edge opposite to the drainage hole 24, that is, the edge that slopes upward is higher than the bottom edge of the external heat dissipation hole 21. Therefore, when water flows into the drainage chamber 2, the external ambient water level needs to be higher than the bottom edge of the external heat dissipation hole 21. Since one side of the bottom wall of the drainage chamber 2 is higher than the bottom edge of the external heat dissipation hole 21, it is higher than the external water level. When water flows into the drainage chamber 2, the higher part of the bottom wall of the drainage chamber 2 is higher than the immersion liquid level in the drainage chamber 2, thus preventing this part from being submerged. The rotating motor 252 of the drive screw in the aforementioned slide groove 25 is located in this part, which can protect the rotating motor 252 when the drainage chamber 2 is submerged, so that the scraper 26 can continue to operate effectively.

[0043] Reference Figure 4 and Figure 5An inner groove 211 is formed on one side wall of the drainage chamber 2 where the external heat dissipation hole 21 is located, making this side wall of the drainage chamber 2 a double-layer structure. Correspondingly, the perforated plate installed in the external heat dissipation hole 21 should also be provided in two layers, but the bottom of the inner groove 211 is located above the drainage hole 24, and the inner groove 211 is not connected to the drainage hole 24; a sealing block 213 is horizontally arranged in the inner groove 211, and a drive cylinder 215 is provided on two opposite sides of the top wall of the inner groove 211. The piston rod of the drive cylinder 215 extends vertically downwards, and the drive cylinder 215... The bottom end of the piston rod is connected to both ends of the top wall of the sealing block 213. The drive cylinder 215 and its piston rod are located on both sides of the external heat dissipation hole 21 to avoid affecting the air outlet area of ​​the external heat dissipation hole 21. The two drive cylinders 215 retract their piston rods simultaneously, so that the sealing block 213 slides upward while maintaining a horizontal state. A sealing membrane 214 is connected between the bottom end of the sealing block 213 and the bottom wall of the inner groove 211. The sealing membrane 214 is a soft membrane structure made of waterproof material. In this embodiment, a polytetrafluoroethylene membrane (PTFE membrane) is used. The length of the sealing membrane 214 is... The length is greater than that of the external heat dissipation hole 21; when the aforementioned drive cylinder 215 is not running, the top edge of the sealing block 213 is flush with the bottom edge of the external heat dissipation hole 21, and the sealing film 214 is folded between the sealing block 213 and the bottom wall of the inner groove 211. At this time, the sealing block 213 is flush with the bottom edge of the external heat dissipation hole 21, and the top side of the sealing block 213 is the bottom end of the external heat dissipation hole 21, preventing hot air and dust blown out from the external heat dissipation hole 21 from accumulating in the inner groove 211; when the sealing component needs to be operated, the drive cylinder 215 drives the sealing... As block 213 moves upward, sealing membrane 214 unfolds under the action of sealing block 213, sealing the external heat dissipation hole 21 between the two layers of perforated plates, greatly reducing the amount of external water flowing into drainage chamber 2. However, external water can squeeze into drainage chamber 2 through the gap between sealing membrane 214 and the side wall of inner tank 211. Therefore, in order to further reduce the amount of water flowing into drainage chamber 2, the area of ​​sealing membrane 214 should be preset so that when sealing block 213 slides above external heat dissipation hole 21, sealing membrane 214 is in a taut and straight state.

[0044] It should be noted that in this embodiment, the length of the sealing membrane 214 should be equal to the length of the inner groove 211, and the gap width between the inner groove 211 and the sealing membrane 214 should be minimized as much as possible.

[0045] Reference Figure 4 After the sealing membrane 214 is opened to close the external heat dissipation hole 21, water from the external environment of the housing 1 may flow into the inner groove 211 along the sealing membrane 214 when it impacts the sealing membrane 214. In order to prevent water from accumulating in the inner groove 211 and not being able to drain, a perforation 212 is provided on the side wall of the inner groove 211 near the drainage chamber 2, so that the inside of the inner groove 211 is connected to the drainage chamber 2. The perforation 212 is opened at the bottom of the inner groove 211, so that the water accumulated in the inner groove 211 flows into the drainage chamber 2 through the perforation 212.

[0046] In this embodiment, the sealing block 213 and the sealing membrane 214 together form a sealing component, which is used to seal the drainage chamber 2 in humid or flooded environments.

[0047] Reference Figure 1 and Figure 4 After the drainage chamber 2 is closed, in order to ensure the cooling effect inside the drainage chamber 2, a cooling component needs to be installed so that its heat dissipation effect is not affected after the drainage chamber 2 is closed. In this embodiment, cold water tanks 27 are provided on the three side walls of the drainage chamber 2 that do not have external heat dissipation holes 21. The provision of cold water tanks 27 makes the side walls of the drainage chamber 2 double-layered. A cold water tank 3 is fixed or formed on the outer wall of the shell 1 opposite to the external heat dissipation holes 21. The cold water tank 3 is connected to a water source through a pipe. A water pump is installed in the cold water tank 3 to draw cold water from the water source and deliver it to the cold water tank 3. The cold water tank 3 is connected to the cold water tank 27, so that the cold water inside the cold water tank 3 is delivered to the cold water tank 27. Thus, in this embodiment, heat in the drainage chamber 2 is absorbed through heat exchange by the cold water in the cold water tank 27. To improve heat exchange efficiency, in this embodiment, the central part of the common side wall of the cold water tank 27 and the drainage chamber 2 is connected and a heat exchange plate is installed. One side of the heat exchange plate is the inner wall of the drainage chamber 2, and the other side is the inner wall of the cold water tank 27. The heat exchange plate is made of a heat-sensitive material, specifically, the heat exchange plate is made of a heat-sensitive ceramic.

[0048] It should be noted that the cold water tank 27 and the inner tank 211 are independent and not connected.

[0049] The implementation principle of an industrial-grade power supply with waterproof components according to an embodiment of this application is as follows: Under normal circumstances, the heat generated by the core power components is dissipated to the outside of the housing 1 through the internal and external heat dissipation holes 21. When the housing 1 is submerged in water due to weather factors such as heavy rain or high air humidity, the drainage, sealing, and cooling components in the drainage chamber 2 are activated.

[0050] First, the enclosed components operate when the outside is only relatively humid.

[0051] When the housing 1 is immersed in water and the water flows into the drainage chamber 2 from the external heat dissipation hole 21, the sealing component operates, sealing the inside and outside of the housing 1. The sealing membrane 214 is taut, greatly reducing the amount of water flowing into the drainage chamber 2. The cooling component operates, ensuring heat dissipation while the sealing membrane 214 is closed.

[0052] This application further discloses a waterproof control system for an industrial-grade power supply with waterproof components. (See also...) Figure 6 A waterproof control system for an industrial-grade power supply with waterproof components includes a central control module 4, a monitoring module 5, a display module 6, and a control module 7.

[0053] The monitoring module 5 is used to monitor the ambient humidity and the humidity inside the drainage chamber 2, and uploads the collected data to the central control module 4. When the shell 1 is immersed in water, the monitoring module 5 measures the immersion water level of the shell 1 and uploads the collected water level data to the central control module 4. In practical applications, sensors are usually selected. In this embodiment, the monitoring module 5 includes liquid level sensors, humidity sensors, liquid level sensors, and humidity sensors installed at the bottom of the outer walls of the shell 1 on multiple sides, and at the bottom of the inner walls of the shell 1 on multiple sides. Among them, a liquid level sensor must be installed at the bottom of the outer wall of the shell 1 on one side of the drainage plate 241.

[0054] The central control module 4 is the central processing device in this embodiment. In actual application, a DSP chip, CPU, etc. can be selected. It receives the collected data uploaded by the monitoring module 5, calculates and analyzes the environmental state of the industrial power supply, and generates corresponding instruction information based on the calculation and analysis results. It controls the control module 7 to take corresponding waterproof and moisture-proof measures in different environments where the industrial power supply is located, according to the corresponding instructions.

[0055] The control module 7 receives instructions from the central control module 4 and controls the operation of the sealing component and the cooling component according to the instructions. Specifically, it controls the rotation motor 252 that slides the scraper 26, the waterproof micro motor 253 that rotates the scraper 26, the water pump, and the drive cylinder 215.

[0056] Display module 6 is connected to central control module 4, displaying the calculation and analysis results of central control module 4 and the real-time surrounding environment of the industrial-grade power supply. This allows control personnel to promptly obtain the operating status of the industrial-grade power supply's waterproof system. When the enclosed components and cooling components are operating, display module 6 should promptly display and provide prompts, indicating to relevant control personnel that the industrial-grade power supply is in a waterproof state. The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
