Description

Technical Field

[0001] The present invention relates to the field of electric power technology, in particular to a moisture-proof sealing device for electric equipment. Background Art

[0002] In a switching power supply, a rectifier diode converts AC mains power into DC power to power subsequent circuits, ensuring unidirectional current conduction and preventing backflow. During the diode production process, in order to prevent the diode from getting damp, it needs to be stored in a dedicated sealing device.

[0003] According to Chinese patent publication number "CN115395375B," a moisture-proof sealing device for electrical equipment includes a housing, a fan fixedly connected to the interior of the housing, an air outlet duct fixedly connected to the housing relative to the fan, the air outlet duct connecting the interior of the housing with the outside world, and a cardboard vertically disposed on the housing near the fan near the air outlet duct. The cardboard completely shields the end of the air outlet duct near the fan. The air outlet duct includes a coaxially arranged inner tube and an outer tube sleeved outside the inner tube. The inner and outer tubes are slidably connected. A first elastic member is fixedly connected to the outer tube relative to the inner tube. The inner tube abuts against the cardboard via the first elastic member. When the cardboard becomes damp, the first elastic member pushes the inner tube to break the cardboard, so that the inner tube faces the fan. The housing is provided with a dry sealing structure. This application has the effect of reducing damage to electrical control equipment caused by humid air inside a distribution box. The device can also store diodes.

[0004] The above patent can prevent moisture from entering the storage box through the heat dissipation holes when in use. However, if the diodes are stacked randomly, complex gaps and channels will be formed, which will hinder the normal flow of air in the sealed box, thereby affecting the dehumidification effect of the dehumidifier.

[0015] 2. This invention utilizes a spray mechanism that uses a push plate to drive a curved slide, allowing the nozzle to reciprocate back and forth, thereby improving the uniformity of moisture-proof paint spraying on diodes. As the diodes roll along the feed slide, the nozzle sprays in all directions. The circular motion drives the first rack, rotating the crown gear, vertical shaft, and stirring rod, stirring the moisture-proof paint and ensuring uniform composition. This further enhances the paint's adhesion to the diodes, strengthens their moisture-proof performance, and ensures more effective moisture-proofing.

[0016] 3. This invention utilizes a cleaning mechanism that utilizes an air pump, air pipe, and air nozzle to remove dust from the diode surface. As the push plate moves upward, the horizontal axis rotates the diode, allowing air from the air nozzle to cover all surfaces of the diode and thoroughly clean the dust. Furthermore, the rotation of the second gear pulls the air nozzle back and forth, further enhancing the cleaning effect of the air from the nozzle on the diode surface. This leaves the diode surface cleaner, thereby improving the adhesion of the moisture-proof paint, ensuring the quality of the moisture-proof treatment, and extending the diode's service life.

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.

An arc groove 44 is provided at the upper right corner of the push plate 43. A feeding slide 45 is provided on the top of the storage box 2. A feeding port 46 is provided through the top of the storage box 2, and the feeding port 46 is arranged above the two storage cavities 47. The inner wall of the storage box 2 is rotatably connected to a rotating shaft 49, and the middle part of the rotating shaft 49 is fixedly connected to a conical block 410. The conical block 410 is arranged inside the feeding port 46 and above the two storage cavities 47. The diodes falling into the feeding port 46 by setting the conical block 410 are sequentially introduced into the interior of the two storage cavities 47.

[0022] Working principle: first, pour the diodes to be stored onto the inclined plate 41, and then the diodes will roll from the inclined plate 41 to the lower right corner and fall into the arc groove 44 on the push plate 43. Then, open the hydraulic cylinder 42 to drive the push plate 43 and the diodes to move upward. When the diodes rise to the top of the storage box 2, they will slide to the right from the arc groove 44 into the feed chute 45, and then slide from the feed chute 45 to the lower right corner into the feed port 46. The first diode to enter the feed port 46 will slide from the right side of the conical block 410 to the right storage chamber 47, and slide down along the bottom arc partition of the right storage chamber 47, and fit the right inner wall of the right storage chamber 47. When the first diode to enter the feed port 46 slides to the bottom of the conical block 410, it will push the conical block 410 to the left by gravity. The lower right corner of the cone block 410 is driven by the cone block 410 to rotate clockwise, and the top of the cone block 410 will fit the right inner wall of the feed port 46.

When the second diode falls into the feed port 46, it will slide from the left side of the cone block 410 to the left storage chamber 47, and push the lower left corner of the cone block 410 to the right by gravity, and drive the cone block 410 to rotate counterclockwise, and the top of the cone block 410 will fit the left inner wall of the feed port 46. This is repeated, and each diode that falls into the storage box 2 will be evenly divided into the two storage chambers 47, thereby improving the dehumidification effect of the dehumidifier 3. The diode in the storage chamber 47 is suspended through the hollow cavity 48 and the partition, so that the dehumidifier 3 can remove the moisture at the bottom of the diode, further improving the dehumidification effect of the dehumidifier 3.
