Abstract
Description
Technical Field
[0001] This utility model relates to the field of power cabinet technology, specifically to a moisture-proof power cabinet. Background Art
[0002] A power cabinet is a type of electrical infrastructure that contains a large number of electrical components. When the power cabinet is working, it generates a lot of heat. In order to protect the electrical components, ventilation windows need to be opened on the power cabinet to effectively dissipate the heat. However, for power cabinets installed in rainy seasons or humid environments, appropriate moisture-proof measures need to be taken to prevent moisture from entering the power cabinet and causing short circuits in electrical components, which could lead to safety accidents.
[0003] To protect the internal electrical components from moisture, existing power cabinets place bags of desiccant at the ventilation windows to absorb moisture from the air. However, the desiccant's moisture absorption effect gradually decreases as it becomes saturated with moisture, requiring frequent replacement. If this is overlooked and the desiccant is not replaced in time, the moisture protection measures will fail, causing damage to the electrical components inside the power cabinet. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a moisture-proof power cabinet, which solves the problem of frequently replacing the desiccant after it has absorbed moisture when using it for moisture protection.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a moisture-proof power cabinet, including a power cabinet body, a moisture-proof box fixedly installed on the top of the power cabinet body, the moisture-proof box including a box body, a box door and an air supply channel, the box door being hinged to the left and right sides of the box body, ventilation openings being provided on the upper and lower sides of the box body, and an air supply channel being fixedly installed inside the box body, the air supply channel being located at the ventilation opening.
[0006] A top cover assembly is slidably installed on the top of the box, a rotating mechanism is rotatably installed inside the box, and a drive mechanism is provided inside the box;
[0007] The surface of the rotating mechanism is provided with a moisture-proof component. The moisture-proof component passes through the interior of the air supply channel. There are two sets of rotating mechanisms, which are symmetrically arranged inside the housing. The rotating parts of the drive mechanism are connected to the two sets of rotating mechanisms respectively. The two ends of the moisture-proof component are respectively wound around the surface of the two sets of rotating mechanisms.
[0008] The power cabinet body includes a cabinet body, a cabinet door, a partition, and a fan. The top of the cabinet body is connected to the bottom of the box body. The cabinet door is hinged to the front side of the cabinet body. A partition is fixedly installed inside the cabinet body. There are two sets of fans, which are located inside the cabinet body below the ventilation opening of the box body.
[0009] The surface of the air supply channel is provided with a groove, and the moisture-proof component passes through the inside of the groove.
[0010] The top cover assembly includes a sliding plate, a cover, and a pin. The sliding plate is fixedly installed on the top of the box, and a slot is provided on the surface of the sliding plate. The cover is slidably installed on the surface of the sliding plate, and a sealing ring is fixedly connected to the bottom of the cover. The pin is slidably inserted into the slot of the sliding plate and fits against the cover.
[0011] The rotating mechanism includes a rotating rod, protrusions, sleeves, and limiting bolts. The rotating rod is rotatably installed inside the housing. Protrusions are fixedly installed on the surfaces of the left and right ends of the rotating rod. The sleeves are slidably installed on the left and right ends of the rotating rod and are inserted into the protrusions. The limiting bolts are threaded on the left and right ends of the rotating rod and fit against the sleeves.
[0012] The drive mechanism includes a motor, a drive wheel, a transmission wheel, and a driven wheel. The motor is located at the bottom of the housing, and the output end of the motor is fixedly installed with the drive wheel through the bottom of the housing. There are two sets of transmission wheels, which are symmetrically arranged. Each set of transmission wheels consists of two transmission wheels connected coaxially. The driven wheel is fixedly installed on the surface of the rotating mechanism. The drive wheel and the transmission wheel are meshed together.
[0013] The moisture-proof component includes a winding belt, desiccant storage strips, and connecting belts. The winding belt is made of breathable material, and desiccant storage strips are fixedly installed inside the winding belt. The desiccant storage strips are filled with silica gel desiccant. The upper and lower sides of the desiccant storage strips have through grooves and are attached to the upper and lower inner walls of the winding belt. There are multiple sets of desiccant storage strips, which are arranged at equal intervals inside the winding belt. Connecting belts are fixedly connected to both ends of the winding belt, and the connecting belts are fixedly connected to the two ends of the two sets of rotating mechanisms.
[0014] The beneficial effects of the utility model are as follows:
[0015] This invention uses a drive mechanism to rotate a rotating mechanism inside the housing. As the rotating mechanism rotates, the moisture-proof components wrapped around the surface of one set of rotating mechanisms are transferred to the surface of another set, thus switching the moisture-proof components located inside the air supply channel. During the process of removing moisture from the gas entering the power cabinet, the moisture-proof components remove moisture. To avoid the inconvenience of frequently replacing the desiccant after it has absorbed moisture, the drive mechanism is periodically activated to control the rotation of the rotating mechanism. This transfers the moisture-proof components that have absorbed a large amount of moisture in the air supply channel from the surface of one set of rotating mechanisms to the surface of another set until the entire set of moisture-proof components is used up. Then, the staff replaces the components, reducing the frequency of desiccant replacement and the workload of the staff. Attached Figure Description

[0024] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.
[0025] A moisture-proof power cabinet includes a power cabinet body 1, a moisture-proof box 2 fixedly installed on the top of the power cabinet body 1, the moisture-proof box 2 including a box body 201, a box door 202, and an air supply channel 203, the box door 202 being hinged to the left and right sides of the box body 201, ventilation openings being provided on the top and bottom sides of the box body 201, and the air supply channel 203 being fixedly installed inside the box body 201, located at the ventilation openings; a top cover assembly 3 being slidably installed on the top of the box body 201, a rotating mechanism 4 being rotatably installed inside the box body 201, and a drive mechanism 5 being provided inside the box body 201; a moisture-proof component 6 being provided on the surface of the rotating mechanism 4, the moisture-proof component 6 passing through the interior of the air supply channel 203, and the number of rotating mechanisms 4 being [missing information]. Two sets of rotating mechanisms 4 are symmetrically arranged inside the housing 201. The rotating parts of the drive mechanism 5 are respectively connected to the two sets of rotating mechanisms 4. The two ends of the moisture-proof component 6 are respectively wound around the surface of the two sets of rotating mechanisms 4. Specifically, the electrical components are stored in the power cabinet body 1, the components inside the moisture-proof box 2 are used to prevent the air entering and leaving the power cabinet body 1 from getting damp, the top opening of the moisture-proof box 2 is sealed by the top cover assembly 3, and the drive mechanism 5 drives the rotating mechanism 4 to rotate inside the moisture-proof box 2, so that the rotating mechanism 4 drives the moisture-proof component 6 on it to be wound. As the rotating mechanism 4 rotates, the moisture-proof component 6 is wound from one set of rotating mechanisms 4 to the surface of the other set of rotating mechanisms 4.
[0026] The power cabinet body 1 includes a cabinet 101, a cabinet door 102, a partition 103, and a fan 104. The top of the cabinet 101 is connected to the bottom of the enclosure 201. The cabinet door 102 is hinged to the front of the cabinet 101. The partition 103 is fixedly installed inside the cabinet 101. There are two sets of fans 104, which are located inside the cabinet 101 and below the ventilation opening of the enclosure 201. Specifically, the partition 103 divides the internal space of the cabinet 101 into a U-shape, so that the heat dissipation airflow enters from the top side of the cabinet 101, passes through the inside of the cabinet 101, and is discharged along the top side, preventing a large amount of moisture near the ground from entering the cabinet 101. The fan 104 blows air to dissipate heat from the electrical components inside the cabinet 101.
[0027] The surface of the air supply channel 203 is provided with a groove, and the moisture-proof component 6 passes through the inside of the groove; specifically, the moisture-proof component 6 is limited by the groove of the air supply channel 203, so that the moisture-proof component 6 stably passes through the air supply channel 203 and is wound on the surface of the rotating mechanism 4.
[0028] The top cover assembly 3 includes a slide plate 301, a cover 302, and a pin 303. The slide plate 301 is fixedly installed on the top of the housing 201. A slot is provided on the surface of the slide plate 301. The cover 302 is slidably installed on the surface of the slide plate 301. A sealing ring is fixedly connected to the bottom of the cover 302. The pin 303 is slidably inserted into the slot of the slide plate 301 and fits against the cover 302. Specifically, the pin 303 limits and supports the cover 302. After the cover 302 slides along the surface of the slide plate 301 to adjust its position, it supports the cover 302 to separate from or fit tightly against the top of the housing 201.
[0029] The rotating mechanism 4 includes a rotating rod 401, a protrusion 402, a sleeve 403, and a limiting bolt 404. The rotating rod 401 is rotatably installed inside the housing 201. The protrusions 402 are fixedly installed on the surfaces of the left and right ends of the rotating rod 401. The sleeve 403 is slidably installed on the left and right ends of the rotating rod 401 and is inserted into the protrusions 402. The limiting bolt 404 is threadedly installed on the left and right ends of the rotating rod 401 and fits against the sleeve 403. Specifically, the sleeve 403 is stably slidably installed on both ends of the rotating rod 401 by means of the protrusions 402, and the rotating rod 401 is limited and fixed by means of the limiting bolt 404.
[0030] The drive mechanism 5 includes a motor 501, a drive wheel 502, a transmission wheel 503, and a driven wheel 504. The motor 501 is located at the bottom of the housing 201. The output end of the motor 501 passes through the bottom of the housing 201 and is fixedly installed with the drive wheel 502. There are two sets of transmission wheels 503, which are symmetrically arranged. Each set of transmission wheels 503 consists of two transmission wheels 503 connected coaxially. The driven wheel 504 is fixedly installed on the surface of the rotating rod 401. The drive wheel 502 and the transmission wheel 503 are meshed together. Specifically, the motor 501 drives the drive wheel 502 to rotate, and the transmission wheel 503 drives the driven wheel 504 to rotate. This causes the driven wheel 504 to drive the two sets of rotating mechanisms 4 to rotate in the same direction, controlling the moisture-proof component 6 to be wound from one set of rotating mechanisms 4 to the surface of the other set of rotating mechanisms 4.
[0031] The moisture-proof component 6 includes a winding belt 601, a desiccant storage strip 602, and a connecting belt 603. The winding belt 601 is made of breathable material. The desiccant storage strip 602 is fixedly installed inside the winding belt 601. The desiccant storage strip 602 is filled with silica gel desiccant. The upper and lower sides of the desiccant storage strip 602 have through grooves and are attached to the upper and lower inner walls of the winding belt 601. There are multiple sets of desiccant storage strips 602, which are arranged at equal intervals inside the winding belt 601. The two ends of the winding belt 601 are fixedly connected to the connecting belt 603, which is fixedly connected to the surface of the two sets of sleeves 403. Specifically, the silica gel desiccant inside the desiccant storage strip 602 adsorbs moisture in the air supply channel 203. The rotating mechanism 4 drives the moisture-proof component 6 to slide through the air supply channel 203, removing the desiccant that has adsorbed a large amount of moisture from the air supply channel 203 and replacing it with unused desiccant.
[0032] In summary: When using this utility model, if the power cabinet is in a humid environment or during the rainy season, the electrical components inside the power cabinet body 1 generate heat. The fan 104 blows air, causing outside air to flow from the ventilation openings of the cabinet 201 and the inside of the air supply channel 203 into the cabinet 101. The heat is carried away through the U-shaped space of the cabinet 101. Moisture in the air is filtered by the moisture-proof component 6 at the air supply channel 203, and the silica gel desiccant in the desiccant storage strip 602 absorbs the moisture. To prevent the desiccant from absorbing too much moisture and reducing its desiccant absorption effect, the motor 501 is periodically started to drive the drive wheel 502 to rotate. Through the transmission wheel 503, the driven wheel 504 drives the rotating rod 401 to rotate. The rotating rod 401 drives the protrusion 402 to rotate, thus rotating the protrusion 402, which in turn rotates the protrusion 402, causing the protrusion 402 to rotate. The surface of the winding belt 601 is transferred to the surface of another set of sleeves 403, pushing the winding belt 601 to slide through the air supply channel 203, so that the desiccant storage strip 602 that absorbs a large amount of moisture is replaced by the unused desiccant storage strip 602, until the moisture-proof component 6 is completely transferred from the surface of one set of sleeves 403 to the surface of another set of sleeves 403. The operator opens the box door 202, tightens the limit bolt 404 to remove the sleeve 403 and the moisture-proof component 6, replaces the moisture-proof component 6 and then resets it, reducing the frequency of desiccant replacement and reducing the workload. When the power cabinet is idle, the cover 302 can be lowered to fit against the top of the box 201, and the pin 303 is inserted to limit and fix the cover 302. The cover 302 seals the ventilation opening at the top of the box 201 to prevent moisture from entering the device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
