Description

Technical Field

[0002] Big data communication fiber optic switch cabinet is a professional equipment used to store, protect and manage network equipment such as fiber optic switches. It is usually made of metal structure, with dustproof, waterproof, fireproof and other functions, and can be installed in environments such as computer rooms or data centers.

[0003] Existing fiber optic switch cabinets are mostly placed in power wells on each floor. These weak wells are mostly interconnected. In buildings with basements and in areas with high groundwater levels or heavy rain, the weak wells on the lower floors will become damp, which may cause damage to the equipment in the fiber optic switch. In addition, salt and other chemicals in a humid environment may also cause equipment failure or performance degradation in the fiber optic switch, and may even cause safety issues such as short circuits or fires. Therefore, a fiber optic switch cabinet that can dehumidify the incoming air is needed. Summary of the invention

The inner side of the torsion disc spring is affixed with a humidity-sensitive cellulose material. The humidity-sensitive cellulose material refers to a cellulose-based material that changes in size, shape or performance under humidity changes. This sensitivity is mainly caused by the hygroscopic properties of the cellulose material. Cellulose is a natural polymer compound composed of cellulose chains and has good hygroscopic properties. When the humidity increases, the cellulose material can absorb moisture in the surrounding environment, causing it to expand by moisture absorption. On the contrary, when the humidity decreases, the cellulose material will release the absorbed moisture, causing its size to shrink.

[0010] The secondary limit platform is fixedly connected to the adjacent side of the L-shaped sliding rod, and the secondary limit platform is fixedly connected to a wedge-shaped platform on the side close to the guide rod.

[0013] The limiting device includes a limiting plate fixed on the two corners of the front side of the placement frame, an auxiliary limiting plate fixedly connected to the side of the limiting plate away from the working equipment, limiting holes equidistantly arranged on the surface of the limiting plate, a manual feedback plate fixedly connected to the side of the auxiliary limiting plate close to the working equipment, a waist-shaped long groove arranged in the middle of the manual feedback plate, circular holes equidistantly arranged on the surface of the manual feedback plate, and a limiting semicircular table rotatably clamped on the inner wall of the circular hole, the spacing of the circular holes is set corresponding to the spacing of the limiting holes, the auxiliary limiting plate is provided with a groove connected to the waist-shaped long groove, the limiting plate is provided with a plurality of equidistantly distributed limiting holes, and the auxiliary limiting plate is fixedly connected to the side close to the working equipment with a manual feedback plate.

[0015] The technical effects achieved by the present invention are:

[0016] According to the present invention, when the humidity of the external air is low, the moisture-sensitive cellulose material on the surface of the torsion spring absorbs less moisture, and the bending degree of the torsion spring is smaller, thereby allowing the external air to flow through the dust filter net 1, the square through hole 1, and the wind shield plate through the air inlet fan and enter the cabinet. When the humidity of the external air exceeds the safety threshold, the moisture-sensitive cellulose material on the surface of the torsion spring absorbs more moisture, causing the bending degree of the torsion spring to increase. At this time, the convex block acts on the adjusting square frame and under the guidance of the connecting rods 1 and 2, the wind shield plate swings and completes the sealing of the top of the square through hole 1. At this time, the external air flows through the dust filter net 1, the square through hole 1, the air guide support plate, the desiccant placement drawer, the vent hole 2, and enters the cabinet, thereby realizing automatic adjustment of the humidity in the air and ensuring the normal operation of the optical fiber switch.

[0017] The present invention drives the elliptical block to rotate by rotating the height-adjusting shaft, so that the primary limit platform is engaged with the limit hole to complete the height limitation, drives the circumferential rod to swing by rotating the cam, and drives the secondary limit platform to engage with the guide rod by the L-shaped sliding rod to complete the height limitation, thereby realizing the load-bearing capacity of the lifting support frame, drives the rack and the air guide frame to move by rotating the gear, and fixes the moving position of the air guide frame under the limitation of the pull piece, realizes the fitting of the air inlets on both sides of the working equipment, facilitates the cooling of the internal components of the working equipment, and realizes the fixation of the working equipment at the same time.

[0018] The present invention completes dust removal on the outer surface of the second dust filter by continuously pulling the pull piece to drive the sliding plate and the dust brush plate to swing. At this time, the air guide frame moves in the opposite direction under the action of the second spring and squeezes the folded airbag, so that the folded airbag blows air to the second dust filter, thereby achieving the purpose of assisting the dust removal of the second dust filter. The operation is simple and convenient for personnel to operate.

[0019] The present invention provides position feedback to the operator's hand through elastic vibration generated when the spherical block on the waist-shaped platform corresponds to the spherical groove on the limiting semicircular platform when the adjustable placement frame is slid, so as to facilitate the operation of the operator.

[0035] See attached Figure 8-11 The air intake dehumidification device 2 includes a fan placement plate 201 fixed to the bottom of the cabinet 1, an air intake fan 202 fixed to the middle of the fan placement plate 201, an air guide frame 203 fixed to the bottom of the fan placement plate 201, a partition plate 204 fixed to the bottom of the air guide frame 203, a vent 205 opened in the middle of the partition plate 204 and connected to the inner wall of the air guide frame 203, vents 206 opened on the left and right sides of the vent 205 of the partition plate 204, a dehumidification block 214 fixed to the bottom of the partition plate 204, a square through hole 207 opened in the middle of the dehumidification block 214, square grooves 208 opened on the left and right sides of the dehumidification block 214, a dust filter 209 slidably inserted at the bottom of the square through hole 207, and a suction cup 209 snapped into the square groove 208. Drawer rack 211, wind guide support plates 212 equidistantly distributed at the bottom of the inner wall of drawer rack 211, desiccant drawer 210 slidably connected to drawer rack 211, wind blocking plates 213 hinged on the left and right sides of square through hole 1 207, adjustment square frame 215 sliding in the middle of the rear side of dehumidification block 214, convex block 217 rotating in the middle of the adjustment square frame 215, torsion disc spring 216 clamped at the rotation axis of convex block 217, wind shield plate 221 rotatably hinged at the top opening of square through hole 1 207, connecting rod 219 fixedly connected to one end of drawer rack 211 near adjustment square frame 215, connecting rod 1 218 hinged at the top of adjustment square frame 215, spring 1 220 fixed on the left and right sides of adjustment square frame 215;

[0036] See attached Figure 8 The second vent hole 206 is connected to the inner wall of the air guide frame 203, the vent hole 1 205 and the vent hole 206 are both connected to the inner wall of the air guide frame 203, the square through hole 1 207 is correspondingly arranged with the vent hole 1 205, the vent hole 206 is correspondingly arranged with the square groove 208, the square through hole 1 207 is connected with the square grooves 208 on both sides, the wind blocking plate 213 blocks the connection between the square through hole 1 207 and the square groove 208 under normal conditions, and the wind blocking plate 213 can only swing from one side of the square through hole 1 207 to the side of the square groove 208.

[0037] Refer to the attached Figure 10-11 The middle part of the torsion spring 216 is fixedly connected to the rotation axis of the protrusion 217, and the end of the torsion spring 216 away from the protrusion 217 is fixedly engaged with the dehumidification block 214. The inner side of the torsion spring 216 is affixed with a humidity-sensitive cellulose material, and the outer wall of the protrusion 217 is in contact with the inner wall of the adjustment square frame 215. Limit blocks are set at the two corners of the adjustment square frame 215. The spring 1 220 applies a downward force to the adjustment square frame 215. The adjacent ends of the connecting rod 1 218 and the connecting rod 2 219 are hinged. The number of the wind shield plate 221 is multiple, and when the wind shield plate 221 is in a horizontal state, the wind shield plate 221 blocks the bottom of the square through hole 1 207, and the desiccant placement drawer 210 is filled with reusable water-absorbing particles.

[0038] In order to alleviate the problems caused by humidity, people often take measures to adjust the moisture sensitivity of cellulose materials. For example, by chemical treatment or adding surface coatings, the hygroscopic properties of cellulose materials can be changed to reduce their response to humidity changes. In addition, reasonable storage and use conditions, such as controlling humidity and temperature, can also help reduce the size and performance changes of moisture-sensitive materials.

[0039] According to the above structure, when the humidity of the outside air is low, the humidity-sensitive cellulose material on the surface of the torsion disc spring 216 absorbs less moisture in the air. Since this material expands when absorbing moisture, the bending degrees of the materials on both sides of the torsion disc spring 216 are different, so that the bending degree of the torsion disc spring 216 as a whole changes, and further causes the protrusion 217 connected to the torsion disc spring 216 to rotate to a certain extent. Therefore;

[0040] Since the torsion disc spring 216 absorbs less moisture, the bending degree of the torsion disc spring 216 is small, so that the torsion force on the protrusion 217 is small, and the adjustment square frame 215 cannot be pushed to contact the limit position set on the surface of the dehumidification block 214;

[0041] When the humidity of the outside air exceeds the safety threshold, the humidity-sensitive cellulose material on the surface of the torsion spring 216 absorbs more moisture, which increases the bending degree of the torsion spring 216, thereby increasing the torsional force on the protrusion 217, and driving the protrusion 217 to apply an upward force to the adjustment square frame 215, so that the adjustment square frame 215 moves up and contacts the limit block on the adjustment square frame 215. At this time, the upward movement of the adjustment square frame 215 drives the connecting rod 1 218 to swing, and then drives the connecting rod 219 to swing, so that the connecting rod 219 drives the wind shield 221 to swing, and completes the blocking of the top of the square through hole 1 207. When the external air humidity drops from a high value to a safe value, the bending degree of the torsion spring 216 decreases with the air humidity. At the same time, under the support of the spring 1 220, the adjustment square frame 215 moves down, so that the wind shield 221 rotates in the opposite direction to reset, thereby ensuring the connection between the square through hole 1 207 and the air guide frame 203.

[0042] At the same time, when the humidity of the outside air is low, the external air is driven by the air inlet fan 202, so that the external air flows into the square through hole 207 through the dust filter 209, flows through the wind shield 221, and is discharged into the cabinet 1. When the humidity of the outside air exceeds the safety threshold, the wind shield 221 blocks the square through hole 207. At this time, driven by the air inlet fan 202, the wind blocking plates 213 blocking the two sides of the square through hole 207 swing, so that the external air flows through the square through hole 207, and then passes between the wind guide support plates 212 of the drawer placement rack 211, and passes through the desiccant placement drawer 210 from bottom to top, and flows into the vent 206, and finally enters the cabinet 1, thereby completing the dehumidification effect of the humid air. At the same time, the water absorption state of the water-absorbing particles can be checked by extracting the desiccant placement drawer 210, so as to facilitate the replacement of the water-absorbing particles.

[0043] Furthermore, the wind guide support plate 212 is provided to divert the air introduced into the square through hole 207, thereby increasing the contact area between the desiccant placement drawer 210 and the humid air, improving the dehumidification effect, and at the same time allowing the water-absorbing particles in the desiccant placement drawer 210 to absorb water more evenly.

[0044] Furthermore, the wind blocking plate 213 is a thin plate, and the density of the material is low, so that its overall weight is light and it can swing under the action of wind.

[0045] Refer to the attached Figure 4 and attached Figure 6The adjustable placement frame 5 includes a placement frame 501 slidably connected to the outer wall of the guide rod 8, a second square through hole 502 opened on the side close to the support frame 10, an air guide frame 503 slid into the second square through hole 502, a sealed circular air cushion 504 fixed to the side of the air guide frame 503 close to the support frame 10, a second spring 505 fixed to the outer wall of the air guide frame 503, a rack 506 fixed to the top of the air guide frame 503, a cooling fan 507 fixed to the inner wall of the air guide frame 503 away from the support frame 10, a second dust filter 508 fixed to the side of the waist-shaped platform 510 away from the support frame 10, and a rotating connection between the placement frame 501 and the air guide frame 503. The setting frame 501 includes a height adjustment shaft 509 at one end away from the guide rod 8, a waist-shaped platform 510 fixed on the transmission shaft of the height adjustment shaft 509, an elliptical block 511 fixed on the transmission shaft of the height adjustment shaft 509, a cam 515 fixed on the elliptical block 511, a circumferential rod 516 fixed on the cam 515, an L-shaped sliding rod 514 slidably connected to the inner wall of the setting frame 501, a secondary limiting platform 513 sliding on the inner wall of the setting frame 501 close to the guide rod 8, a primary limiting platform 517 slidably connected to the inner wall of the setting frame 501 away from the guide rod 8, and a spherical block 518 elastically clamped on the left and right planes of the waist-shaped platform 510.

[0046] See attached Figure 6 The spring 2 505 applies a force to the air guide frame 503 away from the support frame 10, and a limiting platform is provided at the end of the sealed circular air cushion 504 away from the support frame 10. The secondary limiting platform 513 is fixedly connected to the adjacent side of the L-shaped slide bar 514, and the secondary limiting platform 513 is fixedly connected to a wedge-shaped platform on the side close to the guide rod 8. The outer wall of the guide rod 8 is provided with a wedge-shaped groove, and the wedge-shaped groove is correspondingly arranged to the wedge-shaped platform. The end of the L-shaped slide bar 514 away from the guide rod 8 is provided with a vertical waist-shaped groove, and the circumferential rod 516 is clamped in the waist-shaped groove. The primary limiting platform 517 fits with the adjacent surface of the elliptical block 511 and is magnetically connected.

[0047] According to the above structure, by rotating the height adjustment shaft 509, the height adjustment shaft 509 drives the elliptical block 511 to rotate, so that the elliptical block 511 squeezes the primary limit platform 517, so that the primary limit platform 517 is engaged with the limit device 7 to complete the height limit. At the same time, the rotation of the height adjustment shaft 509 will also drive the cam 515 to rotate, and then drive the circumferential rod 516 to swing, so as to achieve the purpose of dragging the L-shaped slide bar 514 to move, and push the wedge-shaped platform on the secondary limit platform 513 to engage with the wedge-shaped groove on the guide rod 8 to complete the height limit, thereby increasing the load-bearing capacity of the support frame 10;

[0048] The rack 506 is driven to move by the dust removal device 6, and then the air guide frame 503 is moved until it fits with the air inlets on both sides of the working equipment 9, and the working equipment 9 is fixed at the same time. The cooling fan 507 allows the air on the outside of the adjustable mounting frame 5 to flow into the air guide frame 503 through the dust filter 508, and finally flows into the working equipment 9 from both sides of the working equipment 9 to achieve cooling of the internal components of the working equipment 9.

[0049] When in use, by rotating the height adjustment shaft 509 to a vertical state, then sliding the placement frame 501 to a suitable height, then placing the equipment and connecting the lines, and then adjusting the adjustable placement frame 5 to the installation position, this method facilitates work operations and has an optimization effect compared to traditional equipment that is inconvenient for workers to install at a lower height. At the same time, the adjustable placement frame 5 can also be flexibly adjusted according to equipment of different thicknesses, thereby improving the applicability of the equipment.

[0050] Furthermore, the rotating end of the height adjustment shaft 509 is in the shape of an elongated strip, and the height adjustment shaft 509 and the elliptical block 511 are both arranged vertically or horizontally, which is convenient for staff to observe and operate.

[0051] Furthermore, the sealed circular air cushion 504 can better fit the outer wall of the working equipment 9, thereby improving the sealing performance of the connection between the working equipment 9 and the air guide frame 503.

[0052] See attached Figure 5-6 The dust removal device 6 includes a manual turntable 601 rotatably connected to the top of the placement frame 501, a ratchet 602 fixed to the bottom of the manual turntable 601, a gear 608 fixed to the bottom of the manual turntable 601, a lever 603 rotatably connected to the top of the placement frame 501 through a torsion spring, a swing rod 604 fixed to the outer wall of the lever 603, a sliding plate 605 slidably connected to the outside of the placement frame 501, a dust brush plate 606 fixed to the bottom side of the sliding plate 605, and a folding airbag 607 fixed to the inner wall of the placement frame 501;

[0054] According to the above structure, the manual turntable 601 is rotated to drive the gear 608 to rotate to achieve the purpose of controlling the air guide frame 503 to slide in the second square through hole 502, and the pull piece 603 is used to achieve the purpose of fixing the moving position of the air guide frame 503. The pull piece 603 can be driven to disengage from the ratchet 602 by moving the swing rod 604, and under the elastic action of the second spring 505, the air guide frame 503 slides backward to reset;

[0055] By continuously pulling the lever 603, the sliding plate 605 is driven to slide, so that the sliding plate 605 drives the dust brush plate 606 to scrape the outer wall of the dust filter net 2 508, thereby achieving the purpose of dust removal on the surface of the dust filter net 2 508. When the air guide frame 503 moves toward the working equipment 9, it will drive the folded airbag 607 to stretch, so that the folded airbag 607 is inflated. When the rocker arm 604 is pulled, the limit of the ratchet 602 is disengaged, so that the air guide frame 503 moves in the opposite direction under the action of the spring 2 505, so that the folded airbag 607 blows air to the dust filter net 2 508, thereby achieving the purpose of assisting the dust removal of the dust filter net 2 508.

[0056] Furthermore, a waist-shaped through groove is provided at the hinge between the swing rod 604 and the sliding plate 605 , and the pull piece 603 has a tendency to swing toward the ratchet wheel 602 under the action of the torsion spring.

[0057] See attached Figure 7 The limiting device 7 includes a limiting plate 701 fixed to the two corners of the front side of the placement frame 501, an auxiliary limiting plate 707 fixedly connected to the limiting plate 701 away from the working device 9, limiting holes 702 equidistantly provided on the surface of the limiting plate 701, a manual feedback plate 703 fixedly connected to the auxiliary limiting plate 707 on the side close to the working device 9, a waist-shaped long groove 706 provided in the middle of the manual feedback plate 703, circular holes 705 equidistantly provided on the surface of the manual feedback plate 703, and a limiting semicircular table 704 rotatably connected to the inner wall of the circular hole 705, and the spacing of the circular holes 705 corresponds to the spacing of the limiting holes 702. The auxiliary limiting plate 707 is provided with a groove connected to the waist-shaped long groove 706, the limiting plate 701 is provided with a plurality of equally spaced limiting holes 702, the auxiliary limiting plate 707 is fixedly connected with a manual feedback plate 703 on the side close to the working equipment 9, a waist-shaped table 510 is slidably connected in the waist-shaped long groove 706, the primary limiting table 517 is provided with a limiting circular table corresponding to the limiting hole 702, a spherical groove is provided on the adjacent side of the limiting semicircular table 704, and the spherical blocks 518 on both sides of the waist-shaped table 510 are arranged corresponding to the spherical groove opened on the adjacent side of the limiting semicircular table 704.

[0058] According to the above structure, when the height adjustment shaft 509 is dragged to slide up and down, the waist-shaped table 510 is driven to slide in the waist-shaped long groove 706. When the spherical block 518 on the waist-shaped table 510 corresponds to the position of the spherical groove on the limiting semicircular table 704, the elastic vibration of the spherical block 518 generates feedback to the operator's hand, thereby achieving the purpose of facilitating the operation of the personnel. At the same time, the rotation of the waist-shaped table 510 will also drive the limiting semicircular table 704 to rotate in the circular hole 705, and it cannot rotate at the position of the non-circular hole 705, which can not only improve the stability of the installation of the adjustable mounting frame 5, but also simplify the operation of the staff.

[0059] The working principle of the present invention is:

[0060] When the humidity of the outside air is low, the moisture-sensitive cellulose material on the surface of the torsion coil spring 216 absorbs less moisture, so that the torsion coil spring 216 absorbs less moisture and the bending degree of the torsion coil spring 216 is smaller, thereby making the torsion force on the protrusion 217 smaller. At this time, the adjustment square frame 215 cannot be pushed to contact the limit position set on the surface of the dehumidification block 214. At this time, the wind shield plate 221 cannot block the square through hole 207, so that the external air is driven by the air inlet fan 202 and passes through the dust filter 207. 9 flows into the square through hole 1 207, flows through the wind shield plate 221, and is discharged into the cabinet 1. When the humidity of the outside air exceeds the safety threshold, the moisture-sensitive cellulose material on the surface of the torsion coil spring 216 absorbs more moisture, which increases the bending degree of the torsion coil spring 216, thereby increasing the torsional force on the protrusion 217, and drives the protrusion 217 to apply an upward force to the adjustment square frame 215, so that the adjustment square frame 215 moves up and contacts the limit block on the adjustment square frame 215. At this time, the adjustment square frame The upward movement of 215 drives the connecting rod 1 218 to swing, and then drives the connecting rod 219 to swing, so that the connecting rod 219 drives the wind shield plate 221 to swing, and completes the blocking of the top of the square through hole 1 207. At this time, driven by the air inlet fan 202, the wind blocking plates 213 blocking both sides of the square through hole 1 207 swing, so that the external air flows through the square through hole 1 207, passes between the air guide support plates 212 of the drawer placement rack 211, passes through the desiccant placement drawer 210 from bottom to top, and flows into the through hole 207. The air hole 206 finally enters the cabinet 1, thereby completing the dehumidification effect of the humid air. At the same time, the water absorption state of the water-absorbing particles can be checked by extracting the desiccant and placing the drawer 210, which is convenient for replacing the water-absorbing particles. When the humidity of the external air drops from a high value to a safe value, the bending degree of the torsion coil spring 216 decreases with the air humidity. At the same time, under the support of the spring 1 220, the adjustment square frame 215 moves downward, so that the wind shield plate 221 rotates in the opposite direction to reset, ensuring the connection between the square through hole 1 207 and the air guide frame 203;

[0061] By rotating the height adjustment shaft 509, the height adjustment shaft 509 drives the elliptical block 511 to rotate, and then the elliptical block 511 squeezes the primary limit platform 517, so that the primary limit platform 517 is engaged with the limit device 7 to complete the height limitation. At the same time, the rotation of the height adjustment shaft 509 will also drive the cam 515 to rotate, and then drive the circumferential rod 516 to swing, so as to achieve the purpose of dragging the L-shaped slide bar 514 to move, and push the wedge-shaped platform on the secondary limit platform 513 to engage with the wedge-shaped groove on the guide rod 8 to complete the height limitation, thereby increasing the load-bearing capacity of the support frame 10. During use, the placement frame 501 can be slid to a suitable height first, and then the equipment can be placed and the line can be connected, and then the adjustable placement frame can be adjusted. 5 to the installation position, this method is convenient for work operation, compared with the traditional equipment at a lower height, which is inconvenient for the staff to install, it has an optimization effect, and the adjustable mounting frame 5 can also be flexibly adjusted according to the equipment of different thicknesses, which improves the applicability of the equipment, and at the same time, the gear 608 can drive the rack 506 to move, and then bring the air guide frame 503 to move until it fits with the air inlet on both sides of the working equipment 9, and at the same time completes the fixation of the working equipment 9, and the cooling fan 507 works to make the air outside the adjustable mounting frame 5 flow into the air guide frame 503 through the dust filter 508, and finally flow into the working equipment 9 through the two sides of the working equipment 9 to achieve the cooling of the internal components of the working equipment 9;

[0062] The purpose of fixing the moving position of the air guide frame 503 is achieved by using the pull piece 603. The pull piece 603 can be driven to disengage from the ratchet 602 by moving the swing rod 604, and the air guide frame 503 can slide backward and reset under the elastic action of the second spring 505.

[0063] By continuously pulling the lever 603, the sliding plate 605 is driven to slide, so that the sliding plate 605 drives the dust brush plate 606 to scrape the outer wall of the dust filter 508, so as to achieve the purpose of dust removal on the surface of the dust filter 508. When the air guide frame 503 moves toward the working equipment 9, the folded air bag 607 is stretched, so that the folded air bag 607 is inflated. When the swing rod 604 is pulled, the limit of the ratchet wheel 602 is disengaged, so that the air guide frame 503 moves in the opposite direction under the action of the spring 505, so that the folded air bag 607 blows air to the dust filter 508, so as to achieve the purpose of assisting the dust removal of the dust filter 508.

[0064] When the height adjustment shaft 509 is dragged to slide up and down, the waist-shaped platform 510 is driven to slide in the waist-shaped long groove 706. When the spherical block 518 on the waist-shaped platform 510 corresponds to the position of the spherical groove on the limiting semicircular platform 704, the elastic vibration of the spherical block 518 generates feedback to the operator's hand, thereby achieving the purpose of facilitating the operation.

[0065] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
