[0002] A rectifier cabinet is a power electronic device that converts alternating current (AC) into direct current (DC), and is widely used in industries, transportation, power and other fields. Its core function is to realize the conversion of electrical energy forms through rectifying elements (such as diodes, thyristors, IGBTs, etc.) to supply power to DC loads or charge batteries.

[0003] Based on different application scenarios, some rectifier cabinets need to be installed outdoors. During the operation of the rectifier cabinet, its internal components will generate heat. To ensure normal operation, a ventilation device is usually set on the cabinet body for heat dissipation. However, in actual applications, when it is rainy, the humidity in the air is high, and water vapor can easily enter the rectifier cabinet through the ventilation device. As a power electronic device, the rectifier cabinet contains a large number of precision electronic components and circuit boards. If it is in a humid environment for a long time, it may lead to problems such as a decrease in insulation performance, corrosion of metal parts, and short circuits in the circuit, which will affect the normal operation of the device and even cause safety accidents.

[0010] Preferably, the drying module includes a condensation chamber arranged in the drying box body. A plurality of groups of condensation pipes are evenly arranged in the condensation chamber. The condensation pipes are connected to a condenser fixedly arranged outside the drying box body.

[0015] The beneficial effects of the present invention: In the present invention, when the external environment is a non-rainy day and the humidity inside the rectifier cabinet body is within the normal range, the air inlet hood and the air inlet groove of the present invention are in a misaligned state. At this time, the distance between the two air inlet hoods is the smallest, and outdoor air can directly enter the rectifier cabinet body through the air inlet groove. Since the outdoor temperature is lower than the temperature inside the rectifier cabinet body, the heat dissipation effect of the rectifier cabinet body can be improved; when the external environment is a rainy day and the humidity inside the rectifier cabinet body exceeds the preset threshold, the present invention can drive the two air inlet hoods to move away from each other through the driving module, so that the air inlet hood covers the air inlet groove, and outdoor air cannot enter the rectifier cabinet body through the air inlet groove. Therefore, external water vapor cannot enter the rectifier cabinet body either. At this time, the rectifier cabinet body can perform internal air circulation. After the heat dissipation fan conveys the air to the drying box body, it can be input into the rectifier cabinet again through the air inlet hood and the air inlet groove. In the present invention, when the two air inlet hoods and the air inlet groove are in a misaligned state, the dust-proof plate on the air inlet hood just covers the air inlet groove, so that outdoor air can only pass through the dust-proof holes and enter the air inlet groove. Therefore, the dust-proof effect can be achieved, effectively preventing dust from directly entering the rectifier cabinet body through the air inlet groove. In the present invention, when it is not rainy, the dust-proof plate is vertically arranged and covers the air inlet groove for dust prevention. When it is rainy, the driving module drives the air inlet covers on both sides to move towards the air inlet groove. The air inlet covers synchronously drive the dust-proof plate to move. During the movement of the dust-proof plate, the first gear at its end will engage with the first rack. When the air inlet covers completely cover the air inlet groove, under the meshing action of the first gear and the first rack, the first gear drives the dust-proof plate to rotate to a horizontal state through the support shaft. Since it is rainy at this time, the attached dust on the dust-proof plate can be washed by rainwater, thereby achieving the effect of cleaning dust and avoiding excessive dust on the dust-proof holes from affecting its dust-proof effect. Correspondingly, when the driving module drives the air inlet covers on both sides to reset, the dust-proof plate can be synchronously driven to reset. In this embodiment, it is not necessary to use manual or other dust removal equipment to remove dust from the dust-proof plate, and the degree of automation is higher, ensuring the dust-proof effect of the rectifier cabinet body.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Embodiment 1 Please refer to Figures 1 - 3 As shown, the present invention is a moisture-proof and dust-removing structure for an outdoor rectifier cabinet, including two groups of air inlet grooves 101 opened on the rectifier cabinet body 1. The two groups of air inlet grooves 101 are symmetrically arranged on one side plate of the rectifier cabinet body 1. On the other side plate of the rectifier cabinet body 1 opposite to the air inlet grooves 101, a group of air outlet grooves 102 are provided; specifically, in this embodiment, by providing the air inlet grooves 101 and the air outlet grooves 102 on the rectifier cabinet body 1, the rectifier cabinet body 1 can be ventilated and cooled through the air inlet grooves 101 and the air outlet grooves 102 to ensure the stable operation of each electronic component inside the rectifier cabinet body 1.

[0021] In this embodiment, an air outlet cover 2 is fixedly installed at the air outlet slot 102, and the air outlet cover 2 is connected to the heat dissipation fan 201 through an air outlet pipe 202; it should be noted that when dissipating heat from the rectifier cabinet body 1 in this embodiment, the heat dissipation fan 201 is started, and the heat dissipation fan 201 can quickly extract the hot air in the rectifier cabinet body 1 (which can be referred to Figure 10 ), so as to improve the heat dissipation efficiency of the rectifier cabinet body 1; wherein, the other end of the heat dissipation fan 201 is connected to the drying box body 4, and a drying module for drying air is provided in the drying box body 4; specifically, a humidity sensor can be set in the rectifier cabinet body 1 in this embodiment, and the humidity sensor can adopt a capacitive or resistive humidity sensor. The specific model of the humidity sensor in this embodiment is not limited, as long as it can monitor the humidity inside the rectifier cabinet body 1; When it is rainy, as the outdoor water vapor enters the rectifier cabinet body 1 through the air inlet slot 101, the humidity sensor monitors the humidity inside the rectifier cabinet body 1. When the monitored humidity exceeds the preset threshold, the drying module can be started to dry the air extracted by the heat dissipation fan 201, so as to avoid excessive humidity inside the rectifier cabinet body 1 affecting the normal operation of electronic components.

[0022] The two air inlet slots 101 are respectively connected to the air inlet box 103 fixed on the rectifier cabinet body 1. An air inlet cover 3 is slidably arranged outside the air inlet box 103, and the two air inlet covers 3 are connected to a driving module that drives them to approach or move away from each other. The other end of the drying box body 4 is connected to the two air inlet covers 3; it can be explained that when the external environment is not rainy and the humidity inside the rectifier cabinet body 1 is within the normal range, the air inlet cover 3 and the air inlet slot 101 in this embodiment are in a misaligned state. At this time, the distance between the two air inlet covers 3 is the smallest, and the outdoor air can directly enter the rectifier cabinet body 1 through the air inlet slot 101. Since the outdoor temperature is lower than the temperature inside the rectifier cabinet body 1, the heat dissipation effect of the rectifier cabinet body 1 can be improved; when the external environment is rainy and the humidity inside the rectifier cabinet body 1 exceeds the preset threshold, the two air inlet covers 3 can be driven by the driving module to move away from each other, so that the air inlet cover 3 covers the air inlet slot 101 (which can be referred to Figure 11 ), and the outdoor air cannot enter the rectifier cabinet body 1 through the air inlet slot 101. Therefore, the external water vapor cannot enter the rectifier cabinet body 1 either. At this time, the rectifier cabinet body 1 can perform internal air circulation. After the heat dissipation fan 201 transports the air to the drying box body 4, it can be input into the rectifier cabinet body 1 again through the air inlet cover 3 and the air inlet slot 101, which can not only effectively isolate the water vapor, but also ensure the heat dissipation effect of the rectifier cabinet body 1.

[0023] As a further solution of this embodiment, it can be referred to Figure 4 And Figure 5, at the mutually remote ends of the two side air inlet covers 3, dust-proof plates 301 are fixedly arranged, and a number of groups of dust-proof holes 302 are formed in the dust-proof plates 301; it can be explained that when the two side air inlet covers 3 are in a misaligned state with the air inlet groove 101, the dust-proof plates 301 on the air inlet covers 3 can just cover the air inlet groove 101, so that the outdoor air can only enter the air inlet groove 101 through the dust-proof holes 302 (reference can be made to Figure 12 ), so the dust-proof effect can be achieved, effectively preventing dust from directly entering the rectifier cabinet body 1 through the air inlet groove 101.

[0024] Embodiment 2 On the basis of Embodiment 1, reference can be made to Figures 4 - 5 , one end of the drying box body 4 away from the air outlet pipe 202 is communicated with the return air pipe 305, the return air pipe 305 is arranged vertically, the two side air inlet covers 3 are respectively communicated with the L-shaped air pipes 304, and the two side L-shaped air pipes 304 are both slidably inserted into the return air pipe 305; specifically, when the driving module drives the two side air inlet covers 3 to lift and lower, the air inlet covers 3 can slide synchronously on both sides of the return air pipe 305, and the pipe walls of the L-shaped air pipes 304 and the return air pipe 305 are slidably attached to ensure the sealing performance of their connection. The gas in the drying box body 4 can flow to the air inlet covers 3 through the return air pipe 305 and the L-shaped air pipes 304; In addition, the return air pipe 305 and the L-shaped air pipes 304 in this embodiment can also be replaced by telescopic pipes, and this embodiment does not limit this.

[0025] Please refer to Figures 7 - 8, when the driving module drives the air inlet hood 3 to move towards the air inlet slot 101, the dust-proof plate 301 is in a misaligned state with the air inlet slot 101. To facilitate the cleaning of the dust-proof plate 301, in this embodiment, two groups of supports 7 are symmetrically and fixedly arranged on the air inlet hood 3. The dust-proof plate 301 is rotatably arranged between the two side supports 7 through a support shaft. A first gear 701 is fixedly arranged at the end of the support shaft. Among them, a first rack 702 for meshing with the first gear 701 is correspondingly and fixedly arranged on the rectifier cabinet body 1. It can be explained that when it is not rainy, the dust-proof plate 301 is arranged vertically and covers the air inlet slot 101 for dust prevention. When it is rainy, the driving module drives the two side air inlet hoods 3 to move towards the air inlet slot 101. The air inlet hood 3 synchronously drives the dust-proof plate 301 to move. During the movement of the dust-proof plate 301, the first gear 701 at its end will mesh with the first rack 702. When the air inlet hood 3 completely covers the air inlet slot 101, under the meshing action of the first gear 701 and the first rack 702, the first gear 701 drives the dust-proof plate 301 to rotate to a horizontal state through the support shaft. Since it is rainy at this time, the attached dust on the dust-proof plate 301 can be washed by rainwater, thereby achieving the effect of cleaning dust and avoiding excessive dust on the dust-proof holes 302 from affecting its dust-proof effect. Correspondingly, when the driving module drives the two side air inlet hoods 3 to reset, the dust-proof plate 301 can be synchronously driven to reset. In this embodiment, there is no need to use manual or other dust removal equipment to remove dust from the dust-proof plate 301, and the automation degree is higher, ensuring the dust-proof effect of the rectifier cabinet body 1.

[0026] Further, when the first gear 701 and the first rack 702 are not meshed, in order to prevent the dust-proof plate 301 from rotating freely, a sleeve 703 is fixedly arranged at the end of the first gear 701 away from the dust-proof plate 301. A plurality of groups of strip-shaped card slots 704 are circumferentially arrayed on the inner wall of the sleeve 703. A telescopic rod 705 is slidably inserted into the sleeve 703. A plurality of groups of strip-shaped card seats 706 corresponding to and slidably engaged with the strip-shaped card slots 704 are fixedly arranged on the telescopic rod 705. An L-shaped bracket 707 is fixedly arranged on the air inlet hood 3. A fastening screw rod 708 fixed to the telescopic rod 705 is spirally arranged in the L-shaped bracket 707. Specifically, since the fastening screw rod 708 is spirally arranged in the L-shaped bracket 707, a certain torque and rotational force are required to drive the fastening screw rod 708 to rotate. Therefore, through the cooperation of the telescopic rod 705 and the sleeve 703, it can achieve a positioning effect on the dust-proof plate 301, prevent the phenomenon of self-rotation of the dust-proof plate 301, and have higher stability.

[0027] Please refer to Figure 4, the driving module includes a screw rod 105 rotatably arranged on one side of the rectifier cabinet body 1. The screw rod 105 is fixed to the driving end of a first motor fixedly arranged on the rectifier cabinet body 1. The thread directions on both sides of the screw rod 105 are opposite. Nuts are symmetrically sleeved on the screw rod 105 in a spiral manner, and the nuts are fixed to the air inlet hood 3 through connecting rods. Specifically, in this embodiment, when adjusting the distance between the two air inlet hoods 3, the first motor can be driven to rotate the screw rod 105. During the movement of the nuts on the screw rod 105, the two air inlet hoods 3 can be driven to approach or move away from each other through the connecting rods. By setting the waterproof shell 104, the normal driving of the servo motor can be prevented from being affected by rainwater.

[0028] Please refer to Figures 5 - 6 and Figure 10 , the drying module includes a condensation chamber 401 arranged in the drying box body 4. A number of groups of condensation pipes 404 are uniformly arranged in the condensation chamber 401. The condensation pipes 404 are connected to a condenser 501 fixedly arranged outside the drying box body 4. Specifically, in this embodiment, through the condensation pipes 404 and the condenser 501, when the water vapor in the rectifier cabinet body 1 passes through the condensation chamber 401, the water vapor condenses into water droplets and falls, thereby achieving the drying effect. The condensation pipes 404 and the condenser 501 are both prior arts, and the specific structures and principles thereof are not elaborated in this embodiment. Wherein, heat dissipation fins 403 can be arranged on one side of each condensation pipe 404 to further improve the heat dissipation effect.

[0029] In this embodiment, in order to collect the condensed water, a water collection box 504 is arranged at the bottom of the condensation chamber 401. The condensed liquid can be discharged into the water collection box 504 for collection. A liquid level sensor and a drain valve can be arranged in the water collection box 504. When the liquid level sensor monitors that the water volume in the water collection box 504 reaches a preset threshold, the drain valve is adjusted to open through the controller to automatically discharge the water in the water collection box 504.

[0030] It should also be noted that since the water vapor in this embodiment is dried by condensation, the temperature of the dried air decreases. Therefore, when it is re-input into the rectifier cabinet body 1 through the air inlet hood 3, the electronic components can be further cooled. Therefore, even if the rectifier cabinet body 1 is in an internal circulation state, its normal heat dissipation will not be affected, and the cooled air can be fully utilized.

[0031] As a further solution of this embodiment, please refer to Figures 5 - 6 , an adsorption chamber 402 is also arranged in the drying box body 4. Two groups of adsorption plates 408 are respectively arranged in the adsorption chamber 402. A number of groups of adsorption grooves are uniformly opened on the adsorption plates 408, and adsorption fillers for adsorbing moisture are filled in the adsorption grooves. Specifically, in order to further dry the water vapor, after the water vapor is condensed, it can enter the adsorption chamber 402. Air can pass through the pores of the adsorption packing. During this process, the adsorption packing can adsorb moisture. The adsorption packing in this embodiment can be made of materials such as activated alumina or silica gel, which is not limited herein, as long as the actual moisture adsorption requirements are met.

[0032] After the adsorption packing adsorbs for a period of time, due to the increase in its saturation, please refer to Figure 3 , Figures 5 - 6 and Figure 10 , in order to avoid affecting the adsorption effect and adsorption efficiency, two sets of first chutes 405 and two sets of second chutes 415 are respectively opened on the box wall of the adsorption chamber 402. The two sets of first chutes 405 are symmetrically opened on the upper and lower box walls, and the two sets of second chutes 415 are symmetrically opened on the upper and lower box walls. On both sides of the chute on the upper box wall close to the inside of the box, first baffles 406 are fixedly arranged, and on both sides of the chute on the lower box wall close to the inside of the box, second baffles 407 are fixedly arranged. An adsorption channel 411 for passing air is formed between the first baffle 406 and the second baffle 407. The adsorption plate 408 is embedded in the adsorption channel 411, and the height of the adsorption plate 408 is the same as the height of the adsorption channel 411; specifically, when the adsorption plate 408 is embedded in the adsorption channel 411, the adsorption channel 411 can be completely filled, so that air can only flow through the adsorption plate 408.

[0033] In this embodiment, a first sealing plate 409 and a second sealing plate 410 are respectively fixedly arranged on the upper and lower sides of the adsorption plate 408. The sizes of the first sealing plate 409, the second sealing plate 410 and the adsorption plate 408 are equal. When the adsorption plate 408 is in the state of being embedded in the adsorption channel 411, the first sealing plate 409 is in sliding fit with the two first baffles 406 on both sides, and the second sealing plate 410 is in sliding fit with the two second baffles 407 on both sides. Among them, two sets of positioning plates 412 are symmetrically fixedly arranged at one end of the second sealing plate 410 far from the adsorption plate 408. The other end of the positioning plate 412 is fixed to the third sealing plate 414. The size of the third sealing plate 414 is equal to that of the adsorption plate 408. A ventilation port 413 is formed between the third sealing plate 414 and the second sealing plate 410; among them, a drying box body 5 is fixedly arranged on the drying box 4. A second gear 601 is rotatably arranged on the drying box body 5. The second gear 601 is fixed to the driving end of the servo motor. The two sides of the second gear 601 are respectively meshed with a third rack 602 and a fourth rack 603. The two sides of the first sealing plates 409 are respectively fixed to lifting plates. The two lifting plates slide through the top wall of the drying box body 5 and are respectively fixed to the third rack 602 and the fourth rack 603. One side opening of the drying box body 5 is arranged on one side of the condenser 501. A drying fan 502 is arranged on the side of the condenser 501 far from the drying box body 5. An air outlet 503 is opened at one end of the drying box body 5 far from the condenser 501; Specifically, in this embodiment, initially, when one set of adsorption plates 408 is in a state of being embedded in the adsorption channel 411, the other set of adsorption plates 408 is located in the drying box body 5. During the actual application process, there is a heat release process when the condenser 501 is operating (this part is prior art and will not be elaborated here). In this embodiment, a drying fan 502 is arranged on one side of the condenser 501. The drying fan 502 can blow the heat generated by the condenser 501 towards the drying box body 5, thereby heating the adsorption plates 408 to eliminate the moisture in the adsorption filler. This embodiment can not only quickly cool down the condenser 501 to ensure its normal operation, but also heat the adsorption plates 408 with the dissipated heat to reduce the saturation of the adsorption filler, so that it always maintains an efficient dehumidification effect and achieves an energy-saving effect.

[0034] Correspondingly, when one set of adsorption plates 408 recovers its saturation, the second gear 601 can be driven to rotate by the servo motor. The second gear 601 can drive the adsorption plates 408 on both sides to move in opposite directions through the third rack 602 and the fourth rack 603. One set of adsorption plates 408 slides towards the drying box body 5, and the other set of adsorption plates 408 moves from the drying box body 5 towards the adsorption channel 411, so that the positions of the two sets of adsorption plates 408 are interchanged, and the treatment of the saturation of the adsorption filler can be alternately carried out to ensure the adsorption effect on the moisture in the air. It should be noted that in this embodiment, by setting the third sealing plate 414, when the adsorption plate 408 moves into the drying box body 5, the third sealing plate 414 can seal the channel between the second baffles 407 on both sides to prevent air leakage, and at the same time, air can flow through the ventilation openings 413 to avoid blocking the air flow (please refer to Figure 6 )

[0035] In addition, the servo motor connected to the second gear 601 is arranged in the waterproof box 6, and the waterproof box 6 is fixed on the rectifier cabinet body 1 to achieve the waterproof effect and ensure its stable operation.

[0036] Furthermore, when the two side air inlet covers 3 and the air inlet box 103 are in a misaligned state, since the dried air will flow through the return air duct 305 and the L-shaped air duct 304 to the air inlet cover 3, in order to allow the air to be discharged from the air inlet cover 3, please refer to Figure 4 、 Figure 8 、 Figures 11 - 12, the two side air inlet boxes 103 are fixed by the connecting plate 106. Two groups of ejector rods 303 are symmetrically and fixedly arranged on the connecting plate 106. On one side of the two side air inlet covers 3 close to each other, air discharge openings 306 are formed. A plug plate 310 is slidably embedded in the air discharge openings 306. Guide shafts 308 are respectively fixedly arranged on both sides of the air discharge openings 306. An L-shaped guide plate 307 fixed to the plug plate 310 is slidably arranged on the guide shafts 308. A telescopic spring 309 is arranged on the guide shafts 308. One end of the telescopic spring 309 is fixed to the L-shaped guide plate 307, and the other end is fixed to the air inlet cover 3. It can be explained that when the air inlet cover 3 is in a communicating state with the air inlet box 103, the plug plate 310 is just in a state of being embedded in the air discharge opening 306 to prevent the air entering the air inlet cover 3 from being discharged through the air discharge opening 306. Correspondingly, when the two side air inlet covers 3 are driven to approach each other, the cover openings of the air inlet covers 3 slide and fit with the connecting plate 106. As they continue to move, the plug plate 310 abuts against the ejector rod 303. Under the abutting action, the plug plate 310 can be driven to slide towards the inner side of the air inlet cover 3 to open the air discharge opening 306, so that the air in the air inlet cover 3 can be discharged through the air discharge opening 306.

[0037] A rectifier cabinet includes a waterproof shell 104 fixed to one side of the rectifier cabinet body 1. A screw rod 105 and a first motor are arranged in the waterproof shell 104. Among them, a waterproof box 6 is also fixedly arranged on the rectifier cabinet body 1. A second motor is fixed in the waterproof box 6. Specifically, the waterproof shell 104 and the waterproof box 6 in this embodiment can effectively improve the waterproof effect of the first motor and the second motor.
