Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance power supply box technology, specifically to a smart moisture-proof mobile maintenance power supply box for hydropower stations. Background Technology
[0002] In the process of power generation, power supply is required for construction, testing, inspection and maintenance of power plants. Since power plants are fixed, the power supply is usually also fixed. When the power plant is under condition maintenance, the power supply needs to be tested. However, since the testing equipment is distributed throughout the power plant and there are too many testing personnel, the power supply boards may not be sufficient, sometimes resulting in tripping and power outages, which affects the efficiency and accuracy of the test. This requires the use of maintenance power supply devices. However, the existing maintenance power supply devices are generally fixed installations. If the interval between power plant maintenance is too long, it is necessary to lay long cables, which increases the complexity of the work, causes great inconvenience to the power supply maintenance work, wastes working time, and affects the progress of the work.
[0003] An existing patent (publication number: CN117410857A) discloses a mobile maintenance power supply box, including a lifting base, a maintenance power supply box body on the lifting base, a heat-conducting mounting plate inside the maintenance power supply box body, multiple electrical components for maintenance on the heat-conducting mounting plate, a heat dissipation mechanism on the upper side of the maintenance power supply box body, the lower part of the heat dissipation mechanism extending into the maintenance power supply box body, an opening on one side of the maintenance power supply box body, a door rotatably fitted inside the opening, an air outlet on one side of the maintenance power supply box body, four support legs at the bottom of the lifting base, a protective frame fixedly fitted on the upper part of the lifting base, and four casters at the bottom of the protective frame.
[0004] Although the aforementioned patent incorporates a heat dissipation mechanism to facilitate the blowing of filtered air onto the heat-conducting mounting plate or electrical components, thus promoting heat dissipation for the electrical components, for mobile maintenance power boxes installed in hydropower stations, the high humidity in the air due to the location of hydropower stations means that even with air filtration through the filter plate, condensation will still occur when the humid air enters the power box and comes into contact with the hot air. This poses a risk of moisture buildup inside the mobile maintenance power box, which could negatively impact its stability. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent moisture-proof mobile maintenance power supply box for hydropower stations, which has the advantages of stable moisture protection and solves the problems mentioned in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart moisture-proof mobile maintenance power supply box for hydropower stations, comprising a box body, an electrical component body being installed inside the box body, and cooling components for cooling being installed on the left and right inner side walls of the box body, the cooling components including air guide plates, the air guide plates being fixed to the inner wall of the box body, a fan being installed on the inner wall of the box body, the input end of the fan being connected to the outside through the box body, the output end of the fan being connected to the air guide plates, an exhaust port being provided on the side of the box body corresponding to the top of the air guide plates, and a guide opening being provided on the side of the air guide plates corresponding to the exhaust port.
[0007] Furthermore, an air inlet filter plate is provided on the side of the housing at the position corresponding to the fan input end.
[0008] The above solution filters the air entering the fan through the air inlet filter plate, preventing external debris from entering the fan and maintaining its stability.
[0009] Furthermore, an exhaust filter plate is installed at the location where the exhaust vent is opened on the side of the housing.
[0010] The above solution protects the exhaust vent with an exhaust filter plate, preventing external debris from entering the air guide plate.
[0011] Furthermore, heat dissipation fins are fixed to the inner wall of the air guide plate.
[0012] The above solution increases the contact area between the air guide plate and the outside air by using heat dissipation fins, thereby assisting the air guide plate to cool down quickly.
[0013] Furthermore, a fixing block is fixed to one side of each of the two air guide plates that are close to each other, a baffle is provided between the air guide plate and the housing, a connecting plate is fixed to the side of the baffle, and multiple insert rods are fixed to the side of the fixing block, with the insert rods passing through the corresponding connecting plate.
[0014] The above scheme uses the movement of the connecting plate to move the baffle, thereby changing the baffle's obstruction of the exhaust port and guide port.
[0015] Furthermore, a dual-axis motor is installed inside the housing. The dual-axis motor is fixed to the housing by a fixing rod. An adjusting threaded rod is installed at the output end of the dual-axis motor. The other end of the adjusting threaded rod passes through a corresponding connecting plate and is threadedly connected to the connecting plate.
[0016] The above scheme uses a dual-axis motor to drive the adjusting threaded rod to rotate, and the rotation of the adjusting threaded rod causes the connecting plate to move.
[0017] Furthermore, the front of the entire unit is equipped with a touch screen body, a face recognition access control machine body, a multi-function meter and a temperature and humidity display, and the upper surface of the housing is equipped with four lifting lugs.
[0018] The above method uses an external lifting device to lift the container by using the lifting lugs.
[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This intelligent moisture-proof mobile maintenance power supply box for hydropower stations uses a cooling component. During normal operation, a baffle blocks the guide opening, and a fan sends outside air to the air guide plate. The air then passes through the air guide plate and is discharged from the exhaust port. During this process, the temperature generated by the electrical components is transferred to the air guide plate, which cools the inside of the box. Since outside air does not enter the area where the electrical components are located, non-contact cooling is achieved, thus achieving stable moisture protection. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] Please see Figure 1 - Figure 6 The intelligent moisture-proof mobile maintenance power supply box for hydropower stations in this embodiment includes a box body 1. The box body 1 is equipped with electrical component bodies 2. The left and right inner side walls of the box body 1 are equipped with cooling components 3 for cooling. The cooling components 3 include air guide plates 301, which are fixed to the inner wall of the box body 1. A fan 302 is installed on the inner wall of the box body 1. The input end of the fan 302 is connected to the outside through the box body 1, and the output end of the fan 302 is connected to the air guide plate 301. An exhaust port is opened on the side of the box body 1 at the position corresponding to the top of the air guide plate 301, and a guide port 303 is opened on the side of the air guide plate 301 at the position corresponding to the exhaust port.
[0024] Please see Figure 2 , Figure 4 and Figure 5 An air inlet filter plate 4 is installed on the side of the housing 1 at the position corresponding to the input end of the fan 302. The air inlet filter plate 4 filters the air entering the fan 302 to prevent external debris from entering the fan 302 and maintain the stability of the fan 302. An exhaust filter plate 5 is installed at the position where the exhaust port is opened on the side of the housing 1. The exhaust filter plate 5 protects the exhaust port to prevent external debris from entering the air guide plate 301.
[0025] Please see Figure 2 , Figure 4 and Figure 5 The inner wall of the air guide plate 301 is fixed with heat dissipation fins 304. The heat dissipation fins 304 increase the contact area between the air guide plate 301 and the outside air, thereby assisting the air guide plate 301 to cool down quickly. The two air guide plates 301 are fixed with fixing blocks 6 on the side that are close to each other. A baffle 7 is provided between the air guide plate 301 and the box 1. A connecting plate 8 is fixed to the side of the baffle 7. Multiple insert rods 9 are fixed to the side of the fixing block 6. The insert rods 9 pass through the corresponding connecting plate 8. The movement of the connecting plate 8 drives the baffle 7 to move. The movement of the baffle 7 changes the obstruction of the baffle 7 to the exhaust port and the guide port 303.
[0026] Please see Figure 4 , Figure 5 and Figure 6The cabinet 1 is equipped with a dual-axis motor 10, which is fixed to the cabinet 1 by a fixing rod. The output end of the dual-axis motor 10 is equipped with an adjusting threaded rod 11. The other end of the adjusting threaded rod 11 passes through the corresponding connecting plate 8 and is threadedly connected to the connecting plate 8. The dual-axis motor 10 drives the adjusting threaded rod 11 to rotate, and the rotation of the adjusting threaded rod 11 drives the connecting plate 8 to move. The front of the cabinet is equipped with a touch screen body 12, a face recognition access control machine body 13, a multi-function meter 14, and a temperature and humidity display 15. The upper surface of the cabinet 1 is equipped with four lifting lugs 16. The lifting lugs 16 are driven by an external lifting device to lift and lower the cabinet 1.
[0027] It should be noted that when the temperature inside the housing 1 is too high, the dual-axis motor 10 is started, which drives the adjusting threaded rod 11 to rotate. The rotation of the adjusting threaded rod 11 drives the connecting plate 8 to move, which in turn drives the baffle 7 to move. The baffle 7 blocks the exhaust port, which in turn causes the fan 302 to drive the air out of the guide port 303 and blow it directly onto the electrical component body 2, thus directly cooling the electrical component body 2.
[0028] The working principle of the above embodiment is as follows: When the temperature inside the housing 1 is within the normal range and does not trigger the high temperature threshold, the dual-axis motor 10 does not start, and the baffle 7 remains in its initial position. At this time, the baffle 7 blocks the guide port 303. After the fan 302 starts, the outside air enters the fan 302 after being filtered by the air inlet filter plate 4 on the side of the housing 1. The fan 302 delivers the air to the inside of the air guide plate 301. The heat dissipation fins 304 on the inner wall of the air guide plate 301 increase the contact area between the air and the air guide plate 301, quickly absorbing the residual heat inside the housing 1. Then, the hot air is discharged from the housing 1 through the exhaust port. The exhaust filter plate 5 can prevent external debris from entering in reverse. During this process, the air always flows in the independent channel formed by the air guide plate 301 and the housing 1, without directly contacting the electrical component body 2, avoiding the contact between the high humidity air and the hot elements on the surface of the components to generate condensation, thus cutting off the risk of moisture return from the path.
[0029] When the temperature and humidity display 15 inside the enclosure 1 detects that the temperature is too high and exceeds the normal threshold, the dual-axis motor 10 outputs power stably through the fixed rod, driving the adjusting threaded rods 11 on both sides to rotate synchronously. The rotation of the adjusting threaded rods 11 drives the connecting plate 8 to move, which in turn drives the baffle 7 to move. When the baffle 7 moves to completely block the exhaust port, the airflow channel in the air guide plate 301 changes. The filtered air delivered by the fan 302 cannot be discharged through the exhaust port, but can only be blown directly onto the electrical component body 2 through the guide port 303 of the air guide plate 301, realizing point-to-point contact cooling and quickly removing the large amount of heat generated by the components. At the same time, since the air has been preliminarily filtered out by the air inlet filter plate 4, and the directional blowing can reduce the residence time of high humidity air in the enclosure 1, combined with the closed structure of the enclosure 1, it can limit the generation of condensate to the greatest extent while efficiently dissipating heat.
