Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically to an outdoor rainproof structure for power distribution cabinets. Background Technology
[0002] A distribution cabinet is a cabinet made of steel used to protect components and ensure their normal operation. Distribution cabinets have a wide range of applications, mainly in the chemical industry, environmental protection industry, power system, metallurgical system, industrial, nuclear power industry, fire safety monitoring, transportation industry, etc.
[0003] Publication No. CN221126604U discloses an outdoor rainproof power distribution cabinet. This device allows for internal and external heat exchange through ventilation holes during cabinet operation. Before entering the cabinet, external air passes through a filter screen, preventing dust and impurities from entering and affecting the heat dissipation of internal components. After a period of use, a motor drives a rotating wheel, and a striking rod, driven by the wheel and limited by the through-holes, intermittently strikes the filter screen, shaking off dust that falls into the inner box of the dust collection bin for easy cleaning later. The top plate provides overall rain protection, preventing moisture from entering the cabinet. Furthermore, in poor weather conditions, an extension plate can be extended to protect the dustproof components from rain. However, this patent still has the following problems in practical use:
[0004] When the device operates through the cabinet, it exchanges heat between the inside and outside through ventilation holes. Before entering the cabinet, the outside air first passes through a filter screen, which blocks dust and impurities carried in the air, preventing them from entering the cabinet and affecting the heat dissipation of internal components. However, the device does not have a waterproof filter screen. When the distribution cabinet is outdoors in windy or rainy weather, rainwater may tilt and pass through the extension plate and filter screen to enter the distribution cabinet, which may cause water damage inside the distribution cabinet. This greatly reduces the safety and lifespan of the device during use and causes inconvenience to the staff.
[0005] An outdoor rainproof structure for power distribution cabinets is proposed to address the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide an outdoor rainproof structure for a power distribution cabinet, in order to solve the problem mentioned in the background art. Currently, when the cabinet is in operation, heat exchange between the inside and outside is carried out through ventilation holes. Before entering the cabinet, the outside air first passes through a filter screen, thus blocking dust and impurities carried in the air and preventing them from entering the cabinet and affecting the heat dissipation of internal components. However, this device does not have a waterproof filter screen. When the power distribution cabinet is exposed to strong winds and heavy rain outdoors, rainwater may tilt and enter the power distribution cabinet through the extension plate and filter screen, which may lead to water ingress and damage to the power distribution cabinet, greatly reducing the safety and lifespan of the device during use.

Limit boxes are symmetrically fixedly installed inside the upper and lower ends of the mounting frame. A sliding rod is slidably connected inside the limit box, and a sliding plate is fixedly connected to one end of the sliding rod. Slots are symmetrically opened on both the upper and lower sides of the baffle. A plug is welded to the end of the sliding plate away from the sliding rod, and the plug is inserted into the slot. A fixing tube is symmetrically fixedly connected to one side of the limit box. A compression rod is slidably connected to one end of the fixing tube, and a first contraction spring is installed inside the fixing tube.
[0009] Preferably, the mounting frame has symmetrical grooves on both sides inside, and a slider is slidably connected inside the groove. A support rod is slidably connected inside the slider. The two ends of the support rod are fixedly connected to the inside of the groove, and the two sides of the baffle are fixedly connected to the slider. A second retraction spring is sleeved on the outside of the support rod.
[0010] Preferably, the moisture-proof component includes a mesh frame slidably connected to the inside of one side of the front of the connection box, and the inside of the mesh frame is filled with desiccant. The top of the distribution cabinet body is provided with a first air hole, and the inside of both sides of the connection box is symmetrically provided with a second air hole. A sliding box is fixedly installed on one side of the front of the connection box, and a bidirectional screw is rotatably connected inside the sliding box. Threaded sleeves are symmetrically threaded at both ends of the bidirectional screw. A movable plate is fixedly installed at the bottom of the threaded sleeve, and an insert plate is fixedly connected to the corresponding side of the movable plate. Grooves are symmetrically provided on both sides of the mesh frame, and the insert plate is inserted into the groove.
[0011] Preferably, a top plate is fixedly installed on the top of the threaded sleeve, and balls are rolledly connected to the upper interior of the top plate. A rolling groove is opened on the top side of the inner side of the sliding box, and the top of the balls is rolledly connected to the interior of the rolling groove.
[0012] Preferably, a rotating block is fixedly installed at one end of the bidirectional screw.
[0013] Preferably, the top of the movable plate extends through the sliding box and is slidably connected to the sliding box.
[0014] Preferably, the end of the extrusion rod away from the fixed tube is fixedly connected to the slide plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The outdoor rainproof structure for a distribution cabinet is as follows: Two sets of baffles are slid inside the mounting frame by the operator. At this time, the two sets of baffles approach and fit together, causing the two sets of rubber pads to deform under pressure. Then, the operator pulls two sets of sliding rods inside the limit box. The movement of the sliding rods drives the movement of the compression rods. At this time, one end of the compression rod slides inside the fixed tube, causing the first compression spring to contract. Utilizing the extension and reset properties of the first compression spring, the multiple inserts are inserted into the slots, thus achieving rapid adjustment of the fixed baffles. This allows the operator to easily adjust the position of the baffles according to the outdoor weather, effectively preventing external rainwater from directly impacting the filter. This design effectively reduces the probability of water entering the distribution cabinet and prevents dust from entering the cabinet due to outdoor dust. It significantly improves the flexibility, safety, and lifespan of the device. By rotating the bidirectional screw, the operator moves two sets of threaded sleeves, which in turn move the moving plate, which in turn moves the insertion plate. The insertion plate then engages with the groove, allowing for quick installation and removal of the mesh frame. The desiccant inside the mesh frame effectively removes moisture from the air inside the distribution cabinet, greatly reducing internal dampness. The quick-installation and quick-removal design of the mesh frame also facilitates easy replacement of the desiccant.
[0016] 1. The operator slides two sets of baffles inside the mounting frame, bringing them closer together and causing the rubber pads to deform under pressure. When the baffles are fully closed within the mounting frame, the operator pulls two sets of sliding rods inside the limiting box. The movement of the sliding rods moves the sliding plate, which in turn moves the pressing rod. At this point, one end of the pressing rod slides inside the fixing tube, causing the first compression spring to contract. The operator then releases the sliding rod, and the spring's extension and return properties allow the inserts to connect with the slots. Since two sets of slots are symmetrically located on both sides of the baffle, the system achieves limiting when the baffle is unfolded outwards and when it is folded together, enabling quick adjustment and fixing of the baffle. This allows the operator to easily adjust the baffle according to outdoor weather conditions. Adjusting the position of the baffle effectively prevents external rainwater from directly impacting the filter, thus greatly reducing the probability of water entering the distribution cabinet. It also prevents outdoor dust from entering the distribution cabinet, significantly improving the flexibility, safety, and lifespan of the device. This provides convenience for operators. The movement of the baffle causes the slider to slide outside the support rod, at which point the second contraction spring contracts or extends, thus buffering the movement of the baffle. Since the two ends of the second contraction spring are fixedly connected to the slider and the slide groove respectively, when the operator releases the restriction of the baffle by the insertion block, the contraction of the second contraction spring allows the two sets of baffles to quickly approach each other, greatly improving the efficiency of the device.
[0017] 2. The desiccant is filled into the mesh frame by the operator, who then inserts the mesh frame into the connection box. At this time, the air inside the distribution cabinet circulates through the first vent, the mesh frame, and the second vent. The desiccant absorbs the moisture in the air inside the distribution cabinet. The operator then rotates the bidirectional screw, which moves the two sets of threaded sleeves in a convergent-unfolding trajectory. The movement of the threaded sleeves moves the moving plate, which in turn moves the insertion plate. When the moving plate is in contact with both ends of the mesh frame, the insertion plate is inserted into the groove, thus achieving quick installation and removal of the mesh frame. The desiccant inside the mesh frame effectively removes moisture from the air inside the distribution cabinet, greatly reducing the chance of moisture accumulation inside the cabinet. Furthermore, the quick-installation and quick-removal design of the mesh frame makes it easy for operators to replace the desiccant, providing convenience during use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-7 The present invention provides a technical solution: an outdoor rainproof structure for a power distribution cabinet, comprising a power distribution cabinet body 1, a connection box 101 fixedly installed on the top of the power distribution cabinet body 1, and a waterproof plate 102 fixedly installed on the top of the connection box 101, and a ventilation component 103 provided on one side of the power distribution cabinet body 1; a waterproof mechanism 2 provided on the side of the power distribution cabinet body 1 near the ventilation component 103, and a moisture-proof component 3 provided inside the connection box 101;
[0028] The waterproof mechanism 2 includes a mounting frame 201 fixedly installed on one side of the distribution cabinet body 1. Baffles 202 are symmetrically slidably connected to the inside of both sides of the mounting frame 201. Rubber pads 203 are fixedly installed on the corresponding side of each baffle 202. Limit boxes 204 are symmetrically fixedly installed inside the upper and lower ends of the mounting frame 201. A sliding rod 205 is slidably connected inside the limit box 204, and a sliding plate 206 is fixedly connected to one end of the sliding rod 205. Slots 207 are symmetrically provided on both the upper and lower sides of the baffles 202. Insert blocks 208 are welded to the end of the sliding plate 206 away from the sliding rod 205, and the insert blocks 208 are inserted into the slots 207. A fixing tube 2 is symmetrically fixedly connected to one side of the inside of the limit box 204. 09, and a squeezing rod 210 is slidably connected inside one end of the fixed tube 209. The end of the squeezing rod 210 away from the fixed tube 209 is fixedly connected to the slide plate 206. The fixed tube 209 is provided with a first contraction spring 211, which can realize the effect of quickly adjusting the fixed baffle 202. This allows the staff to adjust the position of the baffle 202 according to the outdoor weather, thereby effectively preventing external rainwater from directly hitting the filter screen. This greatly reduces the probability of water entering the power distribution cabinet body 1 and also prevents outdoor dust from entering the power distribution cabinet body 1. This greatly improves the flexibility of the device during use, enhances the safety and service life of the device, and brings convenience to the staff during use.
[0029] The mounting frame 201 has symmetrically arranged sliding grooves 2121 on both sides inside, and a slider 212 is slidably connected inside the sliding groove 2121. A support rod 213 is slidably connected inside the slider 212, and both ends of the support rod 213 are fixedly connected to the inner side of the sliding groove 2121. The two sides of the baffle 202 are fixedly connected to the slider 212, and a second contraction spring 214 is sleeved on the outside of the support rod 213. This can achieve a buffering effect when the baffle 202 moves. Since both ends of the second contraction spring 214 are fixedly connected to the slider 212 and the sliding groove 2121 respectively, when the operator releases the restriction of the insert block 208 on the baffle 202, the contraction property of the second contraction spring 214 can make the two sets of baffles 202 quickly move closer to each other, greatly improving the efficiency of the device and bringing convenience to the operator.
[0030] The moisture-proof component 3 includes a mesh frame 301 slidably connected to the inside of one side of the front of the connecting box 101. The mesh frame 301 is filled with a desiccant 302. First air vents 303 are provided on the top of the distribution cabinet body 1, and second air vents 304 are symmetrically provided on both sides of the connecting box 101. A sliding box 305 is fixedly installed on one side of the front of the connecting box 101. A bidirectional screw 306 is rotatably connected inside the sliding box 305. Threaded sleeves 307 are symmetrically threaded onto both ends of the bidirectional screw 306. A movable plate 308 is fixedly installed at the bottom of the threaded sleeve 307. The top of the movable plate 308 passes through the sliding box 305 and is slidably connected to it. An insert plate 309 is fixedly connected to the corresponding side of the movable plate 308. Grooves 310 are symmetrically provided on both sides of the mesh frame 301, and the insert plate 309 is inserted into the grooves 310, thus enabling quick installation and removal of the mesh frame 301. The internal desiccant 302 effectively removes moisture from the air inside the distribution cabinet body 1, thereby greatly reducing the phenomenon of moisture inside the distribution cabinet body 1. The quick-installation and quick-removal design of the mesh frame 301 makes it easy for staff to replace the desiccant 302, bringing convenience to the staff during use. The top plate 311 is fixedly installed on the top of the threaded sleeve 307, and the upper interior of the top plate 311 is connected with rolling balls 312. The sliding box 305 has a rolling groove 313 on the inner top side, and the top of the rolling balls 312 is connected to the interior of the rolling groove 313. The movement of the threaded sleeve 307 drives the movement of the top plate 311. At this time, multiple sets of rolling balls 312 are connected to the rolling groove 313, which makes the movement of the threaded sleeve 307 stable and smooth. A rotating block 314 is fixedly installed on one end of the bidirectional screw 306. The design of the rotating block 314 makes it easy for the staff to operate the bidirectional screw 306.
[0031] Working principle: Before using this type of outdoor rainproof distribution cabinet, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, when the distribution cabinet body 1 encounters strong winds and heavy rain outdoors, the operator slides the two sets of baffles 202 inside the mounting frame 201. At this time, the two sets of baffles 202 approach and fit together, and the two sets of rubber pads 203 are squeezed and deformed. When the two sets of baffles 202 are completely closed inside the mounting frame 201, the operator pulls the two sets of sliding rods 205 to slide inside the limit box 204. The movement of the sliding rods 205 drives the movement of the sliding plate 206, and the movement of the sliding plate 206 drives the compression rod 21. When the movement is 0, one end of the compression rod 210 slides inside the fixed tube 209. At this time, the first contraction spring 211 contracts. Then, the operator releases the slide rod 205. Utilizing the extension and reset property of the first contraction spring 211, the multiple inserts 208 are inserted into the slots 207. Since two sets of slots 207 are symmetrically opened on both sides of the baffle 202, the baffle 202 achieves the effects of limiting its movement when unfolding outwards and limiting its movement when closing, thereby enabling quick adjustment of the fixed baffle 202. This allows staff to easily adjust the position of the baffle 202 according to outdoor weather conditions, effectively preventing rainwater from directly impacting the filter screen and significantly reducing the probability of water entering the power distribution cabinet 1. It also prevents dust from entering the power distribution cabinet 1 due to outdoor dust, greatly improving the flexibility, safety, and lifespan of the device. This provides convenience for staff during use. The movement of the baffle 202 causes the slider 212 to slide outside the support rod 213. At this time, the second contraction spring 214 contracts or extends, thus achieving a buffering effect when the baffle 202 moves. Since the two ends of the second contraction spring 214 are fixedly connected to the slider 212 and the slide groove 2121 respectively, when the staff releases the restriction of the baffle 202 by the plug 208, the contraction of the second contraction spring 214 allows the two sets of baffles 202 to quickly approach each other, greatly improving the efficiency of the device and providing convenience for staff during use.
[0032] Workers fill the mesh frame 301 with desiccant 302 and then insert it into the connection box 101. At this point, the air inside the distribution cabinet 1 circulates through the first vent 303, the mesh frame 301, and the second vent 304. The desiccant 302 absorbs moisture from the air inside the distribution cabinet 1. Then, workers rotate the bidirectional screw 306, causing the two sets of threaded sleeves 307 to move. The two sets of threaded sleeves 307 move in a convergent-spreading trajectory. The movement of the threaded sleeves 307 drives the movement of the moving plate 308, which in turn drives the movement of the insertion plate 309. When the moving plate 308 is in contact with both ends of the mesh frame 301, the insertion plate 309 and the groove 3... The mesh frame 301 is connected by a plug-in joint, which enables quick installation and disassembly. The desiccant 302 inside the mesh frame 301 can effectively remove moisture from the air inside the distribution cabinet body 1, thereby greatly reducing the phenomenon of moisture inside the distribution cabinet body 1. The quick-installation and quick-disassembly design of the mesh frame 301 makes it easy for staff to replace the desiccant 302, bringing convenience to the staff during use. The movement of the threaded sleeve 307 drives the movement of the top plate 311. At this time, multiple sets of balls 312 are located inside the roller groove 313 and are connected by rolling, which makes the movement of the threaded sleeve 307 stable and smooth. The design of the rotating block 314 makes it easy for the staff to operate the bidirectional screw 306.
