Description

Technical Field

[0001] The present invention relates to the technical field of power supply cabinets, and in particular to a DC power supply cabinet. Background Art

[0002] As the "heart protection unit" of the power system, the DC power supply cabinet provides uninterrupted power supply support for grid protection devices, communication dispatching terminals and automation equipment by converting AC power into highly reliable DC power. Its modular redundant architecture (N+1 hot backup) and intelligent monitoring technology (MODBUS protocol) can respond to dispatch instructions and isolate faults in real time. When the main power supply is abnormal, it automatically switches the battery pack to ensure the continuous operation of core equipment. At the same time, the anti-electromagnetic interference design supports the precise control of the intelligent dispatching system and the efficient linkage of the security defense system. Ultimately, it forms a full-chain technical support from fault warning, rapid isolation to emergency recovery, becoming the physical carrier of the "last line of power defense" in large-scale power grid security defense and intelligent dispatching.

[0003] However, as the "power center" of power grid security and intelligent scheduling, the operational reliability of DC power supply cabinets is directly related to system stability. Although existing technologies generally adopt active heat dissipation architectures (such as dual-channel axial fans + multi-directional air ducts) to achieve efficient thermal management, this architecture inevitably has the following problems during forced convection: while the dynamic airflow circulation between the air inlet and outlet can dissipate heat from high-heat components in the cabinet, it also simultaneously introduces humid air, resulting in increased oxidation rate of metal contacts, decreased insulation resistance of PCBs, and even local condensation leading to circuit shorts. To address this issue, we propose a DC power supply cabinet. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a DC power supply cabinet, including a power supply cabinet body 1, and also including:

[0035] Two air inlet channels 2 are symmetrically provided on the power cabinet body 1;

[0036] Two desiccant storage barrels 3 are detachably connected to the two air inlet passages 2. The desiccant storage barrels 3 include a barrel body 38 and a barrel cover 39. The barrel cover 39 is detachably connected to the barrel body 38. The barrel body 38 is provided with a plurality of air holes 41. The desiccant storage barrels 3 are filled with desiccant for drying the air passing through the air inlet passages 2, thereby dehumidifying the air entering the power supply cabinet body 1, thereby reducing the probability of damage to the electrical components in the power supply cabinet body 1.

[0037] The humidity detection element 4 is provided in the power cabinet body 1 and is used to monitor the humidity in the power cabinet body 1 in real time;

[0038] The switching and conducting component 5 is arranged on the power supply cabinet body 1. Specifically, in the initial state of the device, only one air inlet channel 2 is in the conducting state. At this time, the air entering the power supply cabinet body 1 from the outside will pass through a desiccant storage barrel 3. After the device has been operating for a period of time, the desiccant in the desiccant storage barrel 3 tends to be saturated and cannot absorb moisture in the air well, which will cause the humidity in the power supply cabinet body 1 to increase, which is detected by the humidity sensor 34. Then, it controls the two electric push rods 33 to work, push the rectangular blocking plate 3 28 in the previously conducting air inlet channel 2 to block the corresponding ventilation slot 23, and at the same time push the rectangular blocking plate 1 25 to open the connecting slot 24, so that the two circular slots 21 are guided. At the same time, the blocking plate 3 in the previously unconducted air inlet channel 2 is pushed to open the corresponding ventilation slot 23. After that, the air entering the power supply cabinet body 1 will pass through the two desiccant storage barrels 3 in turn, thereby completely utilizing the desiccant in the previously used desiccant storage barrel 3, while avoiding waste and extending the use time of the desiccant in the next desiccant storage barrel 3.

[0039] Subsequently, after the two desiccant storage barrels 3 have worked together for a period of time, the electric push rod 33 is started through program control, thereby driving the rectangular sealing plate 1 25 and the rectangular sealing plate 2 27 in the previously connected air inlet channel 2 to move, thereby blocking the corresponding air inlet channel 2, and at the same time moving the rectangular sealing plate 1 25 and the rectangular sealing plate 2 27 in the previously unconnected air inlet channel 2 to open, so that this air inlet channel 2 is connected to the power cabinet body 1. Then, the staff can directly pull the used desiccant storage barrel 3 out of the circular groove 21, and after replacing the new desiccant, install it into the circular groove 21, so that there is no need to cut off the ventilation when replacing the desiccant, thereby ensuring the safe and continuous operation of the equipment in the power cabinet body 1.

[0040] The power cabinet body 1 is symmetrically provided with a circular groove 21 for installing a desiccant storage barrel 3. The desiccant storage barrel 3 is slidably connected to the inner wall of the circular groove 21.

[0041] The air inlet channel 2 includes an air inlet slot 22 provided on the power cabinet body 1 , and a ventilation slot 23 communicating with the inner cavity of the power cabinet body 1 is provided on the power cabinet body 1 . The air inlet slot 22 is connected to the ventilation slot 23 via the circular slot 21 .

[0042] The switching conductive component 5 includes a connecting slot 24 provided on the power cabinet body 1. The two circular slots 21 are connected through the connecting slot 24. A rectangular blocking plate 1 25 is slidably connected to the power cabinet body 1 and is located between the two circular slots 21. A plurality of rectangular slots 26 are evenly spaced on the rectangular blocking plate 1 25. The rectangular blocking plate 1 25 is moved so that the rectangular slots 26 on it connect to the connecting slot 24, thereby connecting the two circular slots 21.

[0043] A rectangular blocking plate 27 and a rectangular blocking plate 3 28 are respectively provided on both sides of the circular groove 21. The rectangular blocking plate 27 and the rectangular blocking plate 3 28 are both slidably connected to the inner wall of the power cabinet body 1. Specifically, a sliding groove is provided in the power cabinet body 1 to cooperate with the rectangular blocking plate 1 25, the rectangular blocking plate 27 and the rectangular blocking plate 3 28. A plurality of rectangular grooves 26 are also evenly spaced on the rectangular blocking plate 27 and the rectangular blocking plate 3 28. A pushing member 29 is provided in the power cabinet body 1 to drive the rectangular blocking plate 27 and the rectangular blocking plate 3 28 to move so as to connect the air inlet slot 22 and the ventilation slot 23.

[0044] The pusher 29 includes a push plate 31 slidably connected to the power cabinet body 1. One end of the push plate 31 is fixedly connected to the rectangular blocking plate 3 28, and one end of the rectangular blocking plate 27 is fixedly connected to a round rod 32. One end of the round rod 32 slides through the other end of the push plate 31. The outer wall of the round rod 32 is designed with rubber material to provide friction resistance when the push plate 31 moves relative to the round rod 32.

[0045] One end of the rectangular blocking plate 1 25 is fixedly connected to a spring 1 35 fixed to the inner wall of the power cabinet body 1 , a rectangular block 36 is fixedly connected to the rectangular blocking plate 1 25 , and an L-shaped paddle 37 is fixedly connected to the rectangular blocking plate 3 28 , which is used to contact the rectangular block 36 and push it to move during the movement of the rectangular blocking plate 3 28 , and is used to compress the spring 1 35 to provide a self-restoring elastic force for the rectangular blocking plate 3 28 in the process of pushing the rectangular blocking plate 3 28 to move and open the communication slot 24 ;

[0046] Two electric push rods 33 are fixedly connected to the power cabinet body 1, and the extended ends of the two electric push rods 33 are fixedly connected to the two push plates 31;

[0047] Specifically, when the device is working, first insert the two unused desiccant storage barrels 3 into the two circular grooves 21 in sequence, and then complete the installation operation;

[0048] Subsequently, only one electric push rod 33 is started to push, thereby driving the push plate 31 to move, thereby driving the corresponding rectangular blocking plate 3 28 to move and open the ventilation slot 23. At the same time, the push plate 31 moves and uses friction to drive the round rod 32 to move, thereby driving the rectangular blocking plate 2 27 to move and open the air inlet slot 22. After that, when the outside air flows into the power cabinet body 1 through the air inlet channel 2, it needs to be dehumidified by the desiccant storage barrel 3 provided in the air inlet channel 2. Through this series of measures, the humidity level of the air entering the power cabinet body 1 can be significantly reduced, thereby effectively reducing the possibility of damage to the electronic equipment in the power cabinet body 1 due to humidity factors, ensuring that the electronic equipment continues to maintain an efficient and stable working state, and ultimately providing stable and reliable maintenance guarantee for the safety of the power grid;

[0049] As the device continues to operate, the desiccant in the desiccant storage barrel 3 gradually reaches saturation, causing its ability to adsorb moisture in the air to significantly decrease, thereby causing the humidity in the power cabinet body 1 to increase. When the humidity in the power cabinet body 1 exceeds the preset threshold of the humidity sensor 34, the device will trigger the subsequent switching process;

[0050] By starting the electric push rod 33 corresponding to the previously opened air inlet channel 2 to push, the push plate 31 is used to drive the rectangular blocking plate 3 28 to move and block the ventilation slot 23, and at the same time, the L-shaped dial plate 37 is used to push the rectangular block 36 and the rectangular blocking plate 1 25 to move to open the connecting slot 24. In this process, due to the obstruction of the inner wall of the sliding groove in the power cabinet body 1, the rectangular blocking plate 2 27 is limited, and the push plate 31 slides relative to the round rod 32 on the rectangular blocking plate 27, thereby maintaining the open state of the air inlet slot 22. At the same time, the electric push rod 33 corresponding to the previously unopened air inlet channel 2 is started to pull back, and the push plate 31 is used to drive The rectangular blocking plate 3 28 moves to open the connecting slot 24. During this process, the rectangular blocking plate 27 is limited due to the obstruction of the inner wall of the sliding slot in the power cabinet body 1. Then, the push plate 31 slides relative to the round rod 32 on the rectangular blocking plate 27, thereby maintaining the closed state of the air inlet slot 22. After that, the air entering the power cabinet body 1 will first pass through the desiccant storage barrel 3 in the previously opened air inlet channel 2, and then pass through the desiccant storage barrel 3 in the previously unopened air inlet channel 2, thereby fully utilizing the desiccant in the previously used desiccant storage barrel 3, avoiding waste while extending the use time of the desiccant in the next desiccant storage barrel 3.

[0051] Then, after the two desiccant storage barrels 3 have worked together for a period of time, the electric push rod 33 corresponding to the previously connected air inlet channel 2 is activated by program control to perform a pulling action, thereby driving the rectangular blocking plate 1 25 and the rectangular blocking plate 2 27 to move, and the corresponding air inlet channel 2 is blocked. In this process, the rectangular blocking plate 3 28 is pushed by the reset of the spring 1 35 to block the connecting slot 24. At the same time, the electric push rod 33 corresponding to the previously unconnected air inlet channel 2 is activated by program control to perform a pushing action, and the rectangular blocking plate 1 25 and the rectangular blocking plate 2 27 in the previously unconnected air inlet channel 2 are moved open, so that the air inlet channel 2 is connected to the power cabinet body 1; then the staff can directly pull the used desiccant storage barrel 3 out of the circular groove 21, and install the new desiccant into the circular groove 21 after replacing it, so that the ventilation does not need to be cut off when replacing the desiccant, thereby ensuring the safe and continuous operation of the equipment in the power cabinet body 1;

[0052] Furthermore, after switching the air inlet channel 2, if the humidity detected by the humidity sensor 34 still exceeds the standard, the device will connect both air inlet channels 2 to the power cabinet body 1 to dehumidify the incoming air.

[0053] The humidity detection component 4 is a humidity sensor 34 , which is fixedly connected to the inner wall of the inner cavity of the power cabinet body 1 and as close to the air inlet channel 2 as possible. The humidity sensor 34 is electrically connected to the controller of the electric push rod 33 through a wire.

[0054] A circular plate 42 is rotatably connected to the bottom of the barrel body 38, and a hollow rectangular dial plate 43 is fixedly connected to one end of the circular plate 42. The hollow rectangular dial plate 43 is located inside the barrel body 38. A driving member 44 is provided in the power cabinet main body 1, which is used to drive the hollow rectangular dial plate 43 to rotate when driving the circular plate 42 to rotate so as to dial the desiccant. By continuously rotating and dialing the desiccant, the flow speed of the desiccant in a specific space such as a desiccant storage or processing area can be accelerated, so that the desiccant can be more fully in contact with the surrounding environment, thereby improving the desiccant's absorption efficiency of moisture.

[0055] The driving member 44 includes a shaft 45 rotatably connected to the power cabinet body 1. One end of the shaft 45 is fixedly connected to a rotating plate 46. Both ends of the rotating plate 46 are fixedly connected to magnets 47. The circular plate 42 is made of iron and is used to be attracted by the magnets 47 to connect the rotating plate 46 and the circular plate 42.

[0056] A gear disc 1 48 is slidably connected to the shaft 1 45 , and the gear disc 1 48 is rotatably connected to the push plate 31 . A drive motor 49 is fixedly connected to the power cabinet body 1 , and a gear disc 2 51 is fixedly connected to the output end of the drive motor 49 . When the push plate 31 moves, the gear disc 1 48 is driven to move and engage with the gear disc 2 51 . Specifically, the gear disc 1 48 corresponding to the conductive air inlet channel 2 will engage with the gear disc 2 51 , thereby driving the hollow rectangular dial plate 43 to rotate.

[0057] A sliding groove 52 is provided on the shaft 1 45 , and a sliding protrusion 53 is fixedly connected to the gear disc 1 48 . One end of the shaft 1 45 passes through the gear disc 1 48 , and one end of the sliding protrusion 53 is located in the sliding groove 52 and is slidably connected to its inner wall.

[0058] Example 2: Please refer to Figures 1-10 , the present invention provides a technical solution: Example 2 is optimized based on Example 1:

[0059] An annular groove 54 is provided on the barrel cover 39, and a T-shaped latching protrusion 55 is slidably connected to the power cabinet body 1. The T-shaped latching protrusion 55 is provided with an oblique guide groove 56. One end of the rectangular blocking plate 3 28 is fixedly connected to a push rod 57, and one end of the push rod 57 is fixedly connected to a shaft 3 58 with one end located in the oblique guide groove 56. Specifically, when the rectangular blocking plate 1 25 moves to open the ventilation slot 23, the push rod 57 is driven to move, thereby driving the shaft 3 58 to slide along the oblique guide groove 56, thereby driving the T-shaped latching protrusion 55 to embed into the annular groove 54, thereby locking the desiccant storage barrel 3 in use, thereby preventing the staff from pulling out the desiccant storage barrel 3 in use when replacing it;

[0060] A straight guide groove 1 59 is provided on the T-shaped latch 55 and is connected to the oblique guide groove 56, so as to maintain the locked state of the T-shaped latch 55 when the rectangular blocking plate 3 28 continues to be moved. A straight guide groove 2 61 is provided on the T-shaped latch 55 and is connected to the oblique guide groove 56, so as to maintain the unlocked state of the T-shaped latch 55 when the rectangular blocking plate 3 28 is moved.
