A moisture-sensing and closed moisture-proof distribution cabinet

Abstract

The invention discloses a moisture-sensing and adjustable moisture-proof distribution cabinet, which belongs to the technical field of distribution cabinets. The invention adopts a square ventilation pipe to replace the traditional ventilation hole, and through the arrangement of the moisture-sensing and adjustable moisture-proof components, when the external environment is relatively humid, the moisture-sensing driving swelling particles will absorb water and expand, so that part of the driving and closing magnet balls will be squeezed out of the elastic magnetic isolation sphere. At this time, the magnetic isolation effect of the elastic magnetic isolation sphere on the driving and closing magnet balls will be greatly reduced, so that the pipe plug can move upward under the action of the magnetic attraction between the embedded iron block and the driving and closing magnet balls, so that the pipe plug blocks the ventilation pipe, thereby preventing humid air from entering the cabinet through the ventilation pipe, avoiding the cabinet from becoming humid, and greatly improving the safety performance. Moreover, if a small amount of humid air flows into the cabinet before the pipe plug blocks the ventilation pipe, the adjustable moisture-proof component can dry the humid air in the cabinet, thereby further preventing the cabinet from becoming humid.

Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and more specifically to a moisture-sensing and moisture-proof power distribution cabinet. Background Art

[0002] The power distribution cabinet is an important equipment in the power distribution automation system. The power distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. The power distribution cabinet is used in the occasion where the load is relatively dispersed and there are fewer circuits. The power distribution cabinet can distribute the power of a circuit in the upper-level power distribution equipment to the nearest load.

[0003] Since there are many electrical components inside the distribution cabinet, a lot of heat will be generated when it is working. If the heat cannot be dissipated in time, it will affect the normal operation of the distribution cabinet. Therefore, ventilation holes are usually set on the distribution cabinet to dissipate heat.

[0004] Since the ventilation holes directly connect the inside of the power distribution cabinet with the outside environment, when the outside environment is relatively humid, the humid air in the environment will enter the power distribution cabinet through the ventilation holes, causing the inside of the power distribution cabinet to become humid. The humidity inside the cabinet will not only affect the operation of electrical components, but also easily damage electrical components, and even cause safety accidents, posing a safety hazard. Therefore, we propose a moisture-sensing and closed moisture-proof power distribution cabinet. Summary of the invention

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a moisture-sensing and adjustable moisture-proof distribution cabinet. The present invention adopts square ventilation pipes to replace traditional ventilation holes, and through the setting of the moisture-sensing and adjustable components, when the external environment is relatively humid, the moisture-sensing expansion particles will absorb water and expand, so that part of the driving and closing magnet balls will be squeezed out of the elastic magnetic isolation sphere. At this time, the magnetic isolation effect of the elastic magnetic isolation sphere on the driving and closing magnet balls will be greatly reduced, so that the pipe plug can move upward under the action of the magnetic attraction between the embedded iron block and the driving and closing magnet balls, causing the pipe plug to block the ventilation pipe, thereby preventing humid air from entering the cabinet through the ventilation pipe, avoiding the cabinet from becoming humid, and greatly improving the safety performance. Moreover, through the setting of the joint adjustment moisture-proof component, if a small amount of humid air flows into the cabinet before the pipe plug blocks the ventilation pipe, the joint adjustment moisture-proof component can dry the humid air in the cabinet, thereby further preventing the cabinet from becoming humid.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A moisture-sensing and regulating moisture-proof distribution cabinet, comprising a cabinet body, wherein the outer walls on both sides of the cabinet body are connected with square ventilation pipes, and the two ventilation pipes are provided with moisture-sensing and regulating components, and the moisture-sensing and regulating components include a support box, and the ventilation pipe passes through the support box and is fixedly connected thereto, and a pipe plug matching the ventilation pipe is movably provided in the support box, and the pipe plug passes through the outer wall of the bottom end of the ventilation pipe, and the pipe plug is slidably and sealedly connected to the ventilation pipe, and an embedded iron block is embedded in the pipe plug, and the moisture-sensing and regulating components also include an elastic magnetic-insulating sphere arranged above the ventilation pipe, and a cavity is opened in the elastic magnetic-insulating sphere, and the elastic magnetic-insulating sphere is made of elastic magnetic-insulating material. The top of the elastic magnetic-isolating sphere is penetrated and embedded with a hard-connected sphere that matches it, and the hard-connected sphere is fixedly connected to the cabinet through a fixing rod. A driving-closing magnet ball is movably arranged in the elastic magnetic-isolating sphere, and an elastic material bag is movably placed on the top of the driving-closing magnet ball. The elastic material bag is filled with moisture-sensitive driving swelling particles, and the moisture-sensitive driving swelling particles are made of water-absorbing and expanding material. A moisture-sensitive water-conducting rod is penetrated and embedded in the middle of the hard-connected sphere, and the moisture-sensitive water-conducting rod penetrates the outer wall of the elastic material bag and extends and is inserted into the moisture-sensitive driving swelling particles. The moisture-sensitive water-conducting rod is made of water-absorbing and breathable material. A normally-closed seam for ball outlet is opened on the outer wall of the bottom end of the elastic magnetic-isolating sphere.

[0010] Furthermore, a pair of joint-adjustable moisture-proof components are arranged in the cabinet, and the pair of joint-adjustable moisture-proof components correspond to the two moisture-sensing and closing components respectively. The joint-adjustable moisture-proof components include a connecting tube fixedly installed on the inner wall of the top end of the cabinet, and a moisture-absorbing tube matching the connecting tube is fixedly connected to the inner side of the connecting tube. The moisture-absorbing tube is filled with a moisture-absorbing desiccant, and the moisture-absorbing desiccant is made of color-changing silica gel.

[0011] Furthermore, a linkage rod is provided through the outer wall of one side of the moisture absorption cylinder, and the linkage rod is slidingly and sealingly connected to the outer wall of the connecting cylinder. One end of the linkage rod is fixedly connected to a moisture absorption water guiding rod, and the other end of the moisture absorption water guiding rod is fixedly connected to a sealing connecting rod matching it.

[0012] Furthermore, the moisture absorbing and water guiding rod is made of a water absorbing material, the sealing connecting rod penetrates the outer wall of the moisture absorbing cylinder, and the sealing connecting rod is slidably and sealingly connected to the outer wall of the moisture absorbing cylinder.

[0013] Furthermore, the linkage rod passes through the cabinet body and the outer wall of the elastic magnetic-isolating sphere and extends to the interior of the elastic magnetic-isolating sphere, and the linkage rod is connected to the cabinet body and the outer wall of the elastic magnetic-isolating sphere in a sliding and sealing manner. The end of the linkage rod away from the moisture-absorbing water-guiding rod is fixedly connected to a linkage plate, and one end of the linkage plate is against the elastic material bag. Since the expansion of the elastic material bag and the moisture-sensing swelling particles takes a certain amount of time, when the pipe plug blocks the ventilation pipe, a small amount of humid air may have flowed into the cabinet body. Through the setting of the joint adjustment moisture-proof component, the expansion of the elastic material bag will also push the moisture-absorbing water-guiding rod and the sealing connecting rod through the linkage plate and the linkage rod, so that the moisture-absorbing water-guiding rod and the sealing connecting rod slide outside the moisture-absorbing cylinder until part of the moisture-absorbing water-guiding rod slides outside the moisture-absorbing cylinder, so that the moisture-absorbing water-guiding rod can absorb the moisture in the humid air flowing into the cabinet body into the moisture-absorbing desiccant, thereby drying the humid air, and further preventing the cabinet body from becoming humid.

[0014] Furthermore, a light-transmitting insert is arranged above the moisture-absorbing cylinder, and the light-transmitting insert is penetrated and embedded in the top outer wall of the cabinet, and the light-transmitting insert is made of transparent material.

[0015] Furthermore, a color recognition sensor is fixedly connected to the bottom end of the light-transmitting insert, and the top end of the moisture-absorbing cylinder is arranged to be open. Through the joint arrangement of the color recognition sensor, the light-transmitting insert, etc., light can pass through the transparent light-transmitting insert into the moisture-absorbing cylinder, so that the color recognition sensor can identify the color of the moisture-absorbing desiccant. When the moisture-absorbing desiccant absorbs a certain amount of moisture, it will change color. The drying capacity of the moisture-absorbing desiccant after the color change will be reduced. After the color recognition sensor detects the color change of the light-transmitting insert, it will light up a reminder light, thereby sending a reminder to the staff, prompting the staff to replace the moisture-absorbing desiccant in time.

[0016] Furthermore, a dust screen matching the ventilation duct is fixedly connected to the inner wall of the ventilation duct, which can intercept and filter dust in the air, thereby effectively reducing the entry of dust. The pipe plug is made of heat-conductive material, so that after the ventilation duct is blocked by the pipe plug, the heat in the cabinet can be dissipated to the external environment through the pipe plug, thereby reducing the impact of the blockage of the ventilation duct on the heat dissipation efficiency and improving the heat dissipation efficiency when the ventilation duct is blocked.

[0017] Furthermore, an elastic rod is fixedly connected between the bottom end of the pipe plug and the inner wall of the bottom end of the support box. The elastic rod is made of elastic material and can play a supporting role for the pipe plug.

[0018] Furthermore, a pair of elastic suspension ropes are fixedly connected to the driving and closing magnet ball, and the other ends of the pair of elastic suspension ropes are fixedly connected to the inner wall of the hard connection sphere. Through the arrangement of the elastic rod and the elastic suspension rope, when the driving and closing magnet ball moves downward, the elastic suspension rope will stretch and become longer, and when the pipe plug moves upward, the elastic rod will also stretch and become longer, so that when the humidity of the external environment decreases and becomes dry again, the moisture-sensitive driving swelling particles will gradually dry and shrink, so that the elastic suspension rope can gradually rebound, and then the driving and closing magnet ball can gradually move upward until the driving and closing magnet ball returns to the elastic magnetic isolation sphere. With the resetting of the driving and closing magnet ball, the magnetic attraction of the embedded iron block will gradually disappear, so that the elastic rod can rebound, thereby pulling back the pipe plug, resetting the pipe plug, and then the ventilation pipe can automatically resume conduction, thereby improving practicality.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This solution uses a square ventilation pipe to replace the traditional ventilation hole, and through the setting of the humidity sensing and closing component, when the external environment is relatively humid, the humidity sensing expansion particles will absorb water and expand, so that part of the closing magnet balls will be squeezed out of the elastic magnetic isolation sphere. At this time, the magnetic isolation effect of the elastic magnetic isolation sphere on the closing magnet balls will be greatly reduced, so that the pipe plug can move upward under the action of the magnetic attraction between the embedded iron block and the closing magnet balls, causing the pipe plug to block the ventilation pipe, thereby preventing humid air from entering the cabinet through the ventilation pipe, avoiding the cabinet from becoming humid, and greatly improving the safety performance.

[0022] (2) Through the setting of the joint adjustment moisture-proof component, the expansion of the elastic material bag will also push the moisture-absorbing water-guiding rod and the sealing connecting rod through the linkage plate and the linkage rod, so that the moisture-absorbing water-guiding rod and the sealing connecting rod slide outside the moisture-absorbing cylinder until part of the moisture-absorbing water-guiding rod slides outside the moisture-absorbing cylinder, so that the moisture-absorbing water-guiding rod can absorb the moisture in the humid air flowing into the cabinet into the moisture-absorbing desiccant, thereby drying the humid air and further preventing the cabinet from becoming humid.

[0023] (3) Through the combined arrangement of the color recognition sensor, the light-transmitting insert, etc., light can pass through the transparent light-transmitting insert and shine into the desiccant tube, so that the color recognition sensor can recognize the color of the desiccant. When the desiccant absorbs a certain amount of moisture, it will change color. After the color change, the drying capacity of the desiccant will be reduced. After the color recognition sensor detects the color change of the light-transmitting insert, it will light up the reminder light, thereby sending a reminder to the staff, prompting the staff to replace the desiccant in time.

[0024] (4) A matching dust screen is fixedly connected to the inner wall of the ventilation duct. The dust screen can intercept and filter dust in the air, thereby effectively reducing the entry of dust. The pipe plug is made of heat-conductive material, so that after the pipe plug blocks the ventilation duct, the heat in the cabinet can be dissipated to the external environment through the pipe plug, thereby reducing the impact of the ventilation duct blockage on the heat dissipation efficiency and improving the heat dissipation efficiency when the ventilation duct is blocked.

[0025] (5) By setting the elastic rod and the elastic hanging rope, when the driving and closing magnet ball moves downward, the elastic hanging rope will stretch and lengthen, and when the pipe plug moves upward, the elastic rod will also stretch and lengthen, so that when the humidity of the external environment decreases and becomes dry again, the moisture-sensitive driving swelling particles will gradually dry and shrink, so that the elastic hanging rope can gradually rebound, and then the driving and closing magnet ball can gradually move upward until the driving and closing magnet ball returns to the elastic magnetic isolation sphere. With the reset of the driving and closing magnet ball, the magnetic attraction of the embedded iron block will gradually disappear, so that the elastic rod can rebound, so that the pipe plug can be pulled back, so that the pipe plug is reset, and then the ventilation pipe can automatically resume conduction, thereby improving practicality.

[0044] Embodiment 1:

[0045] See also Figures 1-9 A moisture-sensing and regulating moisture-proof distribution cabinet comprises a cabinet body 101, and square ventilation pipes 102 are connected and arranged on the outer walls on both sides of the cabinet body 101, and humidity-sensing and regulating components are arranged on the two ventilation pipes 102, and the humidity-sensing and regulating components comprise a support box 201, and the ventilation pipe 102 passes through the support box 201 and is fixedly connected thereto, and a pipe plug 202 matching the ventilation pipe 102 is movably arranged in the support box 201, and the pipe plug 202 passes through the outer wall of the bottom end of the ventilation pipe 102, and the pipe plug 202 is slidably and sealedly connected to the ventilation pipe 102, and an embedded iron block 203 is embedded in the pipe plug 202, and the humidity-sensing and regulating components also comprise an elastic magnetic isolation sphere 205 arranged above the ventilation pipe 102, and a cavity is opened in the elastic magnetic isolation sphere 205, and the elastic magnetic isolation sphere 205 is made of elastic magnetic isolation material. The top of the elastic magnetic-isolating sphere 205 is penetrated and embedded with a hard-connected sphere 206 that matches it. The hard-connected sphere 206 is fixedly connected to the cabinet 101 through a fixing rod 207. A driving-closing magnet ball 208 is movably arranged in the elastic magnetic-isolating sphere 205. An elastic material bag 209 is movably placed on the top of the driving-closing magnet ball 208. The elastic material bag 209 is filled with moisture-sensitive driving swelling particles 210. The moisture-sensitive driving swelling particles 210 are made of water-absorbing and expanding material. A moisture-sensitive water-conducting rod 211 is penetrated and embedded in the middle of the hard-connected sphere 206. The moisture-sensitive water-conducting rod 211 penetrates the outer wall of the elastic material bag 209 and extends and is inserted into the moisture-sensitive driving swelling particles 210. The moisture-sensitive water-conducting rod 211 is made of water-absorbing and breathable material. A normally closed seam 212 for ball outlet is opened on the outer wall of the bottom end of the elastic magnetic-isolating sphere 205.

[0046] See also Figures 1-9 and Figures 11-12 By setting the humidity sensing and regulating component, the ventilation pipe 102 can replace the traditional ventilation holes to ventilate and dissipate heat. When the external environment is relatively humid, the humidity sensing water guide rod 211 can absorb part of the moisture in the air into the humidity sensing and driving swelling particles 210, so that the humidity sensing and driving swelling particles 210 absorb water and expand, thereby expanding the elastic material bag 209. Figures 11-12As shown, the expansion of the elastic material bag 209 will squeeze the driving and closing magnet ball 208 downward, causing the driving and closing magnet ball 208 to open the normally closed slit 212 for the ball outlet, and causing part of the driving and closing magnet ball 208 to extend out of the elastic magnetic isolation sphere 205 through the normally closed slit 212 for the ball outlet. At this time, the magnetic isolation effect of the elastic magnetic isolation sphere 205 on the driving and closing magnet ball 208 will be greatly reduced, so that the pipe plug 202 can move upward under the action of the magnetic attraction between the embedded iron block 203 and the driving and closing magnet ball 208, causing the pipe plug 202 to block the ventilation pipe 102, thereby preventing humid air from entering the cabinet 101 through the ventilation pipe 102, avoiding the cabinet 101 from becoming humid, and greatly improving the safety performance.

[0047] See also Figure 6 A dust screen 103 matching with the ventilation pipe 102 is fixedly connected to the inner wall thereof, and the dust screen 103 can intercept and filter the dust in the air, thereby effectively reducing the entry of dust. The pipe plug 202 is made of heat-conducting material, so that after the pipe plug 202 blocks the ventilation pipe 102, the heat in the cabinet 101 can be dissipated to the external environment through the pipe plug 202, thereby reducing the influence of the blockage of the ventilation pipe 102 on the heat dissipation efficiency and improving the heat dissipation efficiency when the ventilation pipe 102 is blocked.

[0048] See also Figures 6-8 An elastic rod 204 is fixedly connected between the bottom end of the pipe plug 202 and the inner wall of the bottom end of the support box 201. The elastic rod 204 is made of elastic material. The elastic rod 204 can play a supporting role for the pipe plug 202. A pair of elastic suspension ropes 213 are fixedly connected to the driving and closing magnet ball 208. The other ends of the pair of elastic suspension ropes 213 are fixedly connected to the inner wall of the hard connection sphere 206. Through the arrangement of the elastic rod 204 and the elastic suspension rope 213, when the driving and closing magnet ball 208 moves downward, the elastic suspension rope 213 will stretch and lengthen, and when the pipe plug 202 moves upward, the elastic rod 204 will also The elastic rod 204 can be stretched and lengthened, so that when the humidity of the external environment decreases and becomes dry again, the moisture-sensitive expansion particles 210 will gradually dry and shrink, so that the elastic suspension rope 213 can gradually rebound, and then the driving and closing magnet ball 208 can gradually move up, until the driving and closing magnet ball 208 returns to the elastic magnetic isolation sphere 205. With the reset of the driving and closing magnet ball 208, the magnetic attraction force on the embedded iron block 203 will gradually disappear, so that the elastic rod 204 can rebound, so that the pipe plug 202 can be pulled back and reset, and then the ventilation pipe 102 can automatically resume conduction, thereby improving practicality.

[0049] See also Figures 4-5 and Figure 10A pair of joint adjustment moisture-proof components are arranged in the cabinet 101, and the pair of joint adjustment moisture-proof components correspond to the two humidity sensing and closing components respectively. The joint adjustment moisture-proof components include a connecting tube 301 fixedly installed on the inner wall of the top of the cabinet 101, and a moisture absorption tube 302 matching it is fixedly connected to the inner side of the connecting tube 301. The moisture absorption tube 302 is filled with a moisture absorption desiccant 303, and the moisture absorption desiccant 303 is made of color-changing silica gel. A linkage rod 304 is penetrated on the outer wall of one side of the moisture absorption tube 302. The linkage rod 304 is slidably and sealedly connected to the outer wall of the connecting tube 301. One end of the linkage rod 304 is fixedly connected to a moisture absorption water guide rod 305. The other end is fixedly connected with a sealing connecting rod 306 that matches it. The moisture-absorbing and water-conducting rod 305 is made of water-absorbing material. The sealing connecting rod 306 penetrates the outer wall of the moisture-absorbing cylinder 302, and the sealing connecting rod 306 is slidingly and sealingly connected to the outer wall of the moisture-absorbing cylinder 302. The linkage rod 304 penetrates the outer wall of the cabinet 101 and the elastic magnetic-isolating sphere 205 and extends to the interior of the elastic magnetic-isolating sphere 205, and the linkage rod 304 is slidingly and sealingly connected to the outer wall of the cabinet 101 and the elastic magnetic-isolating sphere 205. The end of the linkage rod 304 away from the moisture-absorbing and water-conducting rod 305 is fixedly connected with a linkage plate 307, and one end of the linkage plate 307 is against the elastic material bag 209.

[0050] See also Figures 4-5 , Figure 10 and Figures 12-13 Since the expansion of the elastic material bag 209 and the moisture-sensing expansion particles 210 takes a certain amount of time, when the pipe plug 202 blocks the ventilation pipe 102, a small amount of humid air may have flowed into the cabinet 101. By setting the joint adjustment moisture-proof component, the expansion of the elastic material bag 209, such as Figures 12-13 As shown, the moisture absorbing water guiding rod 305 and the sealing connecting rod 306 are pushed by the linkage plate 307 and the linkage rod 304 to slide outside the moisture absorbing tube 302 until part of the moisture absorbing water guiding rod 305 slides outside the moisture absorbing tube 302, so that the moisture absorbing water guiding rod 305 can absorb the moisture in the humid air flowing into the cabinet 101 into the moisture absorbing desiccant 303, thereby drying the humid air, and further preventing the cabinet 101 from becoming humid.

[0051] Please refer to 1-2 and Figure 10A light-transmitting block 309 is arranged above the moisture-absorbing cylinder 302. The light-transmitting block 309 penetrates and is embedded in the top outer wall of the cabinet 101. The light-transmitting block 309 is made of transparent material. A color recognition sensor 308 is fixedly connected to the bottom end of the light-transmitting block 309. The top of the moisture-absorbing cylinder 302 is arranged in an open shape. Through the joint arrangement of the color recognition sensor 308, the light-transmitting block 309, etc., light can pass through the transparent light-transmitting block 309 and shine into the moisture-absorbing cylinder 302, so that the color recognition sensor 308 can identify the color of the moisture-absorbing desiccant 303. When the moisture-absorbing desiccant 303 absorbs a certain amount of moisture, it will change color. The drying capacity of the moisture-absorbing desiccant 303 after the color change will be reduced. After the color recognition sensor 308 detects the color change of the light-transmitting block 309, the reminder light 310 will be turned on, thereby reminding the staff and prompting the staff to replace the moisture-absorbing desiccant 303 in time.

[0052] The replacement of the moisture absorbing desiccant 303 can be achieved by setting a corresponding pipeline on the outer wall of the moisture absorbing cylinder 302. This is a well-known technology for those skilled in the art and will not be described in detail here.

[0053] The present invention adopts a square ventilation pipe 102 to replace the traditional ventilation hole, and through the setting of the humidity sensing and closing component, when the external environment is relatively humid, the humidity sensing driving swelling particles 210 will absorb water and expand, so that part of the driving and closing magnetic balls 208 will be squeezed out of the elastic magnetic isolation sphere 205. At this time, the magnetic isolation effect of the elastic magnetic isolation sphere 205 on the driving and closing magnetic balls 208 will be greatly reduced, so that the pipe plug 202 can be upward under the action of the magnetic attraction between the embedded iron block 203 and the driving and closing magnetic balls 208. Move, causing the pipe plug 202 to block the ventilation pipe 102, thereby preventing humid air from entering the cabinet 101 through the ventilation pipe 102, avoiding the cabinet 101 from becoming humid, and greatly improving the safety performance. Moreover, through the setting of the joint adjustment moisture-proof component, if a small amount of humid air flows into the cabinet 101 before the pipe plug 202 blocks the ventilation pipe 102, the joint adjustment moisture-proof component can dry the humid air in the cabinet 101, thereby further preventing the cabinet 101 from becoming humid.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
