Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and in particular to a drawer-type distribution box with a dehumidification structure. Background Art

[0002] Drawer-type distribution boxes are modular power distribution equipment primarily used for power distribution, circuit protection, and load control. Their core advantage lies in their use of removable modular units (such as circuit breakers and contactors), enabling rapid maintenance, replacement, and capacity expansion. They also offer high reliability, a compact structure, and excellent isolation performance, making them widely used in industrial, commercial, and large-scale building power distribution systems.

[0003] Humidity is a significant factor affecting the reliability and lifespan of drawer-type distribution boxes, especially in humid, rainy environments or those with large temperature fluctuations. High humidity or condensation can adversely affect the box's electrical performance, mechanical structure, and safe operation. Traditional drawer-type distribution boxes either lack dehumidification mechanisms, which can easily lead to condensation inside the cabinet in high-humidity environments. This can cause metal components to rust, degrade insulation performance, and potentially lead to safety hazards such as short circuits and leakage. Alternatively, they employ simple dehumidification mechanisms, which are unable to monitor humidity in real time and automatically intervene, posing the risk of electrical failure in long-term humid environments. Summary of the Invention

[0004] The purpose of the present invention is to provide a drawer-type distribution box with a dehumidification structure. The elastic closing component can be used to make the drawer boxes arranged and slidably connected in the inner cavity of the main box be in an elastic normally closed state. In conjunction with the use of the vertical moving component and the pushing component, the pushing block can be used to form the action of pushing the passive column, so as to achieve the purpose of automatically pulling out any group of drawer boxes, thereby improving the automation efficiency. The automatic rotation of the centrifugal fan blades can not only form a dehumidified air circulation action, but also drive the rotation of the dehumidification filter cylinder of the cylindrical structure through the transmission mechanism, so as to efficiently perform dehumidification work.

[0005] The object of the present invention is achieved through such a technical solution, a drawer-type distribution box with a dehumidification structure, comprising a box assembly, an elastic closing assembly, a vertical movement assembly, a push assembly and a dehumidification assembly, wherein the box assembly comprises a main box body, the elastic closing assembly comprises an opening and closing connecting rod and a passive column, the vertical movement assembly comprises a slide, the push assembly comprises a push block, and the dehumidification assembly comprises a dehumidification filter cartridge and a moisture adsorption cartridge; The inner cavity of the main box is vertically arranged and slidably connected to the drawer box, and the back of the main box is elastically slidably connected to the sliding sleeve. One end of the opening and closing connecting rod is screwed to one side of the rear part of the drawer box, and the other end is screwed to the sliding sleeve. The passive column is fixed to one side of the sliding sleeve. The slide that can automatically rise and fall is located at the back of the main box. A movable toothed belt is installed on the top of the slide, and the push block is fixed to one side of the toothed belt. A centrifugal fan is installed at the inner bottom of the main box body. The dehumidification filter cartridge is also fixed to the inner bottom of the main box body and is located on one side of the centrifugal fan. The moisture adsorption cartridge is screwed into the inner cavity of the dehumidification filter cartridge. The centrifugal fan outlet is connected to the inner cavity of the dehumidification filter cartridge, and the inlet is connected to the inner cavity of the main box body. The rotating shaft of the moisture adsorption cartridge is transmission-connected to the rotating shaft of the centrifugal fan.

[0006] The use process of the technical solution of the present invention is as follows: In this distribution box, each group of functional units is installed in a different drawer box, and the functional units installed in each group of drawer boxes can be independently withdrawn; Under the action of the lateral elastic supporting force of the sliding sleeve itself, the opening and closing connecting rod screwed between the sliding sleeve and the rear part of the drawer box can form a normally closed working state of the drawer box; Since each group of drawer boxes is provided with a slot for installing electrical components, the groups of drawer boxes arranged and installed in the main box are in an air-connected state. After starting the rotary drive mechanism connected to the centrifugal fan, the inlet of the centrifugal fan can be connected to the air of each group of drawer boxes. The air extraction force generated by the centrifugal fan can extract the moist air in each group of drawer boxes and enter the inner cavity of the dehumidification filter cartridge. The air is then adsorbed and dried by the moisture adsorption cylinder installed in the dehumidification filter cartridge and discharged to the outside. Moreover, after the centrifugal fan blades rotate, they can also drive the rotation of the cylindrical moisture adsorption cylinder, so that different positions of the moisture adsorption cylinder dynamically contact the outlet end of the centrifugal fan. This not only utilizes the cylindrical structure of the moisture adsorption cylinder to increase the usable area of the moisture adsorption cylinder, but also realizes that different positions of the moisture adsorption cylinder are in direct contact with the outlet end of the centrifugal fan. When a certain group of drawer boxes needs to be pulled out to inspect or maintain the electrical components in the group of drawer boxes, the toothed belt and the push block are moved to a position facing the group of drawer boxes by the automatically lifting slide; The automatic movement of the toothed belt can drive the push block to form a lateral movement, so that the push block can overcome the supporting elastic force of the set of sliding sleeves after contacting the passive column, push the sliding sleeves, and the sliding sleeves can push the set of drawer boxes outward through the opening and closing connecting rods.

[0007] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) The present invention not only has a drawer box arranged in a sliding connection in the inner cavity of the main box body, but also has a sliding sleeve elastically slidably connected to the back of the main box body, and uses an opening and closing connecting rod screwed to the sliding sleeve and the rear side of the drawer box to enable each group of drawer boxes to be in an elastic normally closed state. Moreover, since the drawer box is in the elastic normally closed state, the screw connection position of the opening and closing connecting rod and the rear side of the drawer box and the sliding sleeve are far away from each other. Only when the drawer box is pulled out, the opening and closing connecting rod can be rotated open under the push of the sliding sleeve, thereby achieving the purpose of providing a transmission structure for the pulling out and closing action of the drawer box on the basis of reducing the occupied space; (2) The present invention also provides a sliding frame that can automatically move up and down on the back of the main box body, which can drive the toothed belt and the push block to move to a position opposite to each group of passive columns. The toothed belt drives the lateral movement of the push block, which can form a lateral pushing action of the push block on the passive columns at different positions, thereby forming an automatic extraction action of each group of drawers, with a high degree of automation; (3) The present invention not only provides a centrifugal fan and a moisture adsorption cylinder at the bottom of the inner cavity of the main box body, but also arranges the moisture adsorption cylinder into a cylindrical structure, and screws it into the inner cavity of the dehumidification filter cylinder, and drives the rotating shaft of the moisture adsorption cylinder to connect with the rotating shaft of the centrifugal fan blade, thereby not only realizing the dehumidification effect of each group of drawer boxes in the inner cavity of the main box body, but also utilizing the cylindrical structure formed by the moisture adsorption cylinder to improve the utilization rate of the moisture adsorption cylinder larger than the connection position of the centrifugal fan outlet and the dehumidification filter cylinder, and furthermore, when the moisture adsorption cylinder and the centrifugal fan blade rotate synchronously, different positions of the moisture adsorption cylinder can be connected to the connection position of the centrifugal fan outlet and the dehumidification filter cylinder in a surrounding manner, thereby achieving the purpose of improving the utilization efficiency of the moisture adsorption cylinder.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] like Figures 1-18 As shown, a drawer-type distribution box with a dehumidification structure, the main box 101 in the box assembly 1 is set as the basis, the inner cavity of the main box 101 is vertically arranged and slidably connected with a drawer box 107, and each group of drawer boxes 107 can form an independent modular functional unit, the back of the main box 101 is elastically slidably connected with a sliding sleeve 204, and each group of sliding sleeves 204 is directly opposite to the drawer box 107, one end of the opening and closing connecting rod 207 is screwed to one side of the rear part of the drawer box 107, and the other end is screwed to the sliding sleeve 204, which can form an elastic normally closed state of the drawer box 107, and the passive column 208 is fixed to one side of the sliding sleeve 204; The slide 302, which can automatically rise and fall, is located at the back of the main box 101. A movable toothed belt 404 is installed on the top of the slide 302. A push block 409 is fixed to one side of the toothed belt 404, which can drive the push block 409 to form a linear movement within a certain range. The carriage 302 can drive the toothed belt 404 to move up and down, so that the push block 409 moves to a position facing each set of passive columns 208; A centrifugal fan 502 is installed at the inner bottom of the main box 101. The dehumidification filter cartridge 512 is also fixed to the inner bottom of the main box 101 and is located on one side of the centrifugal fan 502. The moisture adsorption cartridge 514 is screwed into the inner cavity of the dehumidification filter cartridge 512. The outlet of the centrifugal fan 502 is connected to the inner cavity of the dehumidification filter cartridge 512, and the inlet is connected to the inner cavity of the main box 101. The rotating shaft of the moisture adsorption cartridge 514 is connected to the rotating shaft of the centrifugal fan 502 by transmission, so that the blades of the centrifugal fan 502 and the moisture adsorption cartridge 514 can rotate synchronously. Here's how it works: Each group of functional units in the distribution box is installed in a different drawer box 107. The functional units installed in each group of drawer boxes 107 can be independently withdrawn, which is convenient for maintenance or replacement and reduces downtime. Under the action of the lateral elastic support force of the sliding sleeve 204 itself, the opening and closing connecting rod 207 screwed between the sliding sleeve 204 and the rear part of the drawer box 107 can form a normally closed working state of the drawer box 107; Since each group of drawer boxes 107 is provided with a slot for installing electrical components, the groups of drawer boxes 107 arranged and installed in the main box 101 are in an air-connected state. After starting the rotary drive mechanism connected to the centrifugal fan 502, the inlet of the centrifugal fan 502 can be made to be in an air-connected state with each group of drawer boxes 107. The air extraction force generated by the centrifugal fan 502 can extract the moist air in each group of drawer boxes 107 and enter the inner cavity of the dehumidification filter cartridge 512. The moist air is adsorbed and dried by the moisture adsorption cartridge 514 installed in the dehumidification filter cartridge 512 and then discharged to the outside. Moreover, after the blades of the centrifugal fan 502 rotate, they can also drive the rotation of the cylindrical moisture adsorption cylinder 514, so that different positions of the moisture adsorption cylinder 514 can dynamically contact the outlet end of the centrifugal fan 502. This not only utilizes the cylindrical structure of the moisture adsorption cylinder 514 to increase the usable area of the moisture adsorption cylinder 514, but also realizes that different positions of the moisture adsorption cylinder 514 are in direct contact with the outlet end of the centrifugal fan 502, which not only improves the dehumidification efficiency of the moisture adsorption cylinder 514, but also increases its service life. When it is necessary to pull out a certain group of drawer boxes 107 to inspect or maintain the electrical components in the group of drawer boxes 107, the toothed belt 404 and the push block 409 are moved to a position facing the group of drawer boxes 107, that is, facing the group of passive columns 208, by the automatically elevating slide 302; The automatic movement of the toothed belt 404 drives the push block 409 to move horizontally, so that after the push block 409 contacts the passive column 208, it can overcome the supporting elastic force of the set of sliding sleeves 204 and push the sliding sleeves 204. The sliding sleeves 204 can push the set of drawer boxes 107 outward through the opening and closing connecting rods 207. Furthermore, when the slide 302 drives the toothed belt 404 and the push block 409 to move up and down, each group of passive columns 208 will not interfere with the push block 409 .

[0014] The specific structure of the box assembly 1 and the elastic closing assembly 2 is as follows Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, a rear shell plate 102 is fixedly installed on the back of the main box body 101, and a rear cover body 103 is connected to the rear back of the rear shell plate 102 to provide space for the vertical moving component 3 and the pushing component 4; A front connecting frame 104 is arranged and fixedly connected to the front opening of the main box body 101. Each group of drawer boxes 107 passes through the gaps between different adjacent front connecting frames 104 and is inserted into the inner cavity of the main box body 101. The front connecting frame 104 can not only improve the supporting strength and stability of the main box body 101, but also facilitate the separation of each group of drawer boxes 107. Drawer slide rails 105 are arranged and fixed on both sides of the inner cavity of the main box body 101, and the drawer box 107 is slidably connected to the main box body 101 through the drawer slide rails 105; The rear shell 102 has air holes 106 arranged in the main body, which can provide movement space for the opening and closing connecting rod 207 and facilitate air circulation. The front cover of the drawer box 107 is connected to the drawer plate 108; The dehumidification chamber 109 is located at the bottom of the inner cavity of the main box 101 and is used to provide an installation space for the dehumidification component 5. The front end cover of the dehumidification chamber 109 is connected to the chamber cover 110; Component mounting slots 111 are provided on different drawer surfaces of the drawer box 107 for installing electrical components. A humidity sensor 112 is also installed in the inner cavity of each group of drawer boxes 107 to monitor the humidity of the environment inside different drawer boxes 107; The outer bottom of the drawer box 107 is fixedly connected to a bottom rack 113, and an electric cylinder 114 is fixedly installed inside each group of front connecting frames 104. The locking teeth 115 are fixedly connected to the top of the telescopic rod of the electric cylinder 114. Driven by the movement of the telescopic rod of the electric cylinder 114, the locking teeth 115 cooperate with the locking action of the bottom rack 113 to form a lock, which can not only make each group of drawer boxes 107 stay in the pulled-out position stably, but also make each group of drawer boxes 107 stably locked in the closed position, thereby improving the safety effect; The transverse columns 201 are fixed to the rear back of the rear shell 102 through the column seats 202 at both ends, and the transverse columns 201 are staggered with the air holes 106. The sliding sleeves 204 on the same side are slidably connected to the transverse columns 201. The top of each set of sliding sleeves 204 is vertically fixedly connected to the vertical shaft 206. The rear side of the drawer box 107 is fixedly connected to the opening and closing rotary seat 203. One end of the opening and closing connecting rod 207 is screwed to the opening and closing rotary seat 203, and the other end is screwed to the vertical shaft 206. Each set of transverse columns 201 is sleeved with a top spring 205. One side of the top spring 205 is fixed to the sliding sleeve 204, and the other side is fixed to the column base 202. The elastic support formed by the top spring 205 can make the sliding sleeve 204 be located away from the opening and closing rotary seat 203 in the natural state, and the opening and closing connecting rod 207 screwed between the opening and closing rotary seat 203 and the vertical shaft 206 is used to form an elastic normally closed state of the drawer box 107; Moreover, since a bottom rack 113, an electric cylinder 114 and a locking tooth 115 are provided between the bottom of the drawer box 107 and the front connecting frame 104, in conjunction with the use of the vertical moving component 3 and the pushing component 4, not only can each group of drawer boxes 107 be automatically drawn out, but each group of drawer boxes 107 can also form a stable stopping action after being drawn out. Moreover, since a humidity sensor 112 is installed in each group of drawer boxes 107, the humidity of the local space formed by each group of drawer boxes 107 can be independently monitored, and the monitoring results can be displayed. Real-time feedback is given to the external automatic control system, which can control the automatic lifting and movement of the slide 302 and the automatic movement of the toothed belt 404 to automatically pull out the drawer box 107 with the humidity meeting the standard. After the drawer box 107 with the humidity meeting the standard is pulled out, the air circulation rate between the other groups of drawer boxes 107 remaining in the inner cavity of the main box body 101 will increase, so that according to the monitoring conditions of the humidity sensor 112 in each group of drawer boxes 107, the drawer box 107 with excessively high humidity can be dehumidified in a targeted and rapid manner.

[0015] The specific structure of the vertical moving component 3 and the pushing component 4 is as follows Figure 10 、 Figure 11 and Figure 12 As shown, vertical sliding posts 301 are symmetrically and vertically fixedly connected in the inner cavity of the rear cover 103, and both ends of the slide 302 are slidably connected to different vertical sliding posts 301 respectively; A lead screw slide 303 is fixedly mounted in the middle of the slide 302. A lead screw motor 307 is fixedly connected to the inner bottom end of the rear cover 103 via a U-shaped frame 306. A lead screw top rotating seat 304 is fixedly mounted on the inner top end of the rear cover 103. One end of the lead screw 305 is screwed to the lead screw top rotating seat 304, and the other end is fixedly connected to the rotating shaft of the lead screw motor 307. The lead screw slide 303 is cooperatively connected to the lead screw 305. After the screw motor 307 is started, it can drive the screw 305 to rotate and form a transmission with the screw slide 303, so that the slide 302 moves vertically guided by the sliding cooperation formed with the vertical slide column 301; A photoelectric reflection sensor 308 is mounted on one side of the top surface of the slide 302, and a photoelectric receiving piece 309 is fixedly mounted on one side of the inner cavity of the rear cover 103. The photoelectric reflection sensor 308 and the photoelectric receiving piece 309 together constitute a photoelectric sensing module. The photoelectric reflection sensor 308 senses the photoelectric receiving pieces 309 at different positions as the slide 302 moves, thereby facilitating the accurate movement of the slide 302 to a position where the push block 409 and different passive columns 208 are horizontally opposite each other. Both sides of the main body of the slide 302 are fixedly installed with push shaft seats 401. Each set of push shaft seats 401 is rotatably connected to a push shaft 402. The top of each set of push shaft 402 is fixed with a toothed pulley 403. The toothed belt 404 is sleeved between different toothed pulleys 403. A push motor 405 is fixedly mounted on the bottom end of one side of the slide 302. The rotating shaft of the push motor 405 is fixedly connected to the bottom end of one set of push shafts 402, which can drive the toothed belt 404 to form an automatic movement. The top surface of the carriage 302 is further fixedly connected to a pair of inner support plates 406. The inner support plates 406 on the same side contact the inner straight surface of the toothed belt 404. This prevents the toothed belt 404 from deforming due to its own elasticity during movement, thereby improving the lateral movement stability of the push block 409. A grating decoder 408 is fixedly installed on the outside of the other side of the toothed belt 404, and a grating ruler 407 is installed on the top surface of the slide 302 and is located between the two sets of inner support plates 406. The grating ruler 407 and the grating decoder 408 together constitute a grating measurement system to achieve high-precision measurement of the lateral movement position of the toothed belt 404 and the push block 409, and achieve high-precision lateral displacement of the push block 409 by feeding back to the external automatic control system. By pushing the passive column 208 by the push block 409, the drawer box 107 can be pulled out to any position with high precision.

[0016] The specific structure of the dehumidification component 5 and the circulation component 6 is as follows Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 As shown, the dehumidification assembly 5 is entirely located in the inner cavity of the dehumidification chamber 109, the outer end of the integrated cover 501 is connected between a group of front connecting frames 104 and the rear shell plate 102 at the bottom, the drive motor 503 is fixedly installed at the bottom of the inner cavity of the main box 101, and the top body of the drive motor 503 is arranged and fixed with a fixed column 511.

The adapter pulley 506 and the adapter bevel gear 508 are both plugged and fixed in the adapter shaft 505. A drive pulley 510 is plugged and fixed in the rotating shaft of the drive motor 503. A belt 507 is sleeved between the drive pulley 510 and the adapter pulley 506. When the drive motor 503 drives the blades of the centrifugal fan 502 to rotate, the adapter shaft 505 and the adapter bevel gear 508 are synchronously driven to rotate. The interior of the moisture adsorption cylinder 514 is fixedly connected to the inner frame 515, and the middle part of the inner frame 515 is fixedly connected to the inner shaft 516 in the horizontal direction. The inner end of the inner shaft 516 is screwed to the bottom end of the inner cavity of the dehumidification filter cylinder 512, and the outer end surface is fixedly connected to the convex seat 517, which can form an internal circulation space when the moisture adsorption cylinder 514 rotates. The middle part of the filter plate 521 is fixedly connected to the plug-in shaft 518, and the middle part of the plug-in shaft 518 is provided with an inner plug hole 519. The inner surface of the inner plug hole 519 is provided with a concave groove 520. The plug-in shaft 518 forms a sliding plug-in fit with the inner shaft 516 and the convex seat 517 through the inner plug hole 519 and the concave groove 520 without twisting. After the plug-in shaft 518 is inserted into place, the inner end surface of the filter plate 521 contacts the outer end of the inner frame 515, and the filter plate 521 is squeezed and contacted in the inner hole of the moisture adsorption cylinder 514; The outer end opening of the dehumidification filter cartridge 512 is covered with a side cover 522, and a central rotary seat 523 is fixedly installed in the middle of the side cover 522. The plug-in shaft 518 is rotatably connected to the central rotary seat 523.

When the adapter bevel gear 508 rotates, the coordinated transmission formed by the adapter bevel gear 508 and the rotating bevel gear 509 drives the rotation of the plug-in shaft 518, thereby driving the synchronous rotation of the dehumidification filter cartridge 512 and the moisture adsorption cartridge 514. An air outlet duct 524 with a corner structure is connected to one side of the main body of the side cover 522. The inlet of the air outlet duct 524 is within the filtering range of the filter plate 521 and does not interfere with the transmission formed by the rotating bevel gear 509 and the adapter bevel gear 508. The outlet end of the air outlet pipe 524 passes through the side wall of the main housing 101 and extends to the outside thereof. The air sucked into the inner cavity of the dehumidification filter cartridge 512 by the centrifugal fan 502 is dehumidified by the moisture adsorption cartridge 514 and then filtered by the filter plate 521. The dry and clean air is discharged through the air outlet pipe 524. The lower end of the side wall of the rear cover 103 is connected to a conical pipe seat 602, and the inlet end of the conical pipe seat 602 and the outlet end of the air outlet pipe 524 are connected to a blowing connecting pipe 601; The blowing cylinder 603 is fixedly connected to the bottom surface of the carriage 302 in a transverse direction. The air inlet seat 605 is fixedly connected to the middle part of the bottom end of the blowing cylinder 603. A spiral air pipe 604 is connected between the outlet end of the conical tube seat 602 and the inlet end of the air inlet seat 605. A long blowing slot 606 is transversely opened on the side of the blowing cylinder 603 opposite to the rear shell plate 102. The dry clean air discharged through the air outlet pipe 524 can enter the interior of the blowing horizontal cylinder 603 and be blown out horizontally through the blowing long slot 606; Since the slide 302 can automatically move up and down, the air holes 106 are arranged in the main body of the rear shell 102. As the slide 302 automatically moves up and down, the blowing horizontal cylinder 603 can be driven to move to different vertical positions, blowing clean and dry air into the drawer boxes 107 at different positions, accelerating air circulation and improving dehumidification efficiency. Furthermore, the spiral air tube 604 is a spiral telescopic structure, which can not only telescope along with the movement of the slide 302 but also will not interfere with the push fit formed by the push block 409 and the passive column 208 .
