Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, and in particular to a space-adjustable low-voltage withdrawable switch cabinet. Background Art

[0002] Low-voltage switchgear is a kind of power control cabinet. The external line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. It is widely used in many industries. There are many types of low-voltage switchgear: fixed, withdrawable and welded, etc. With the continuous progress of society, the national power grid and the people's electrical equipment are becoming more and more extensive, and the use of switchgear is also increasing.

[0003] Since there are usually many power control components arranged inside the switch cabinet, more heat will be generated inside when in use. In order to meet the heat dissipation requirements of the power switch cabinet, vents are opened on the surface of the power switch cabinet. However, since there are many locations where the power switch cabinet is installed, in some rainy areas, since the switch cabinet is exposed to water for a long time, some rainwater can easily enter the interior of the switch cabinet, which can easily cause the internal parts to be corroded and damaged. At present, most switch cabinet equipment has the vents set to an inclined shape with the inside higher and the outside lower to reduce the possibility of rainwater entering. However, the practical effect of this measure is often not good, and there is still the possibility that external environmental factors may affect the safety of internal components through the vents. Therefore, the existing switch cabinets are still insufficient in terms of auxiliary functions around the vents and protecting the safety of internal components, and the actual use effect needs to be improved.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention can change the position between the adjustment plate 1 and the adjustment plate 2 by setting structures such as the adjustment plate 1, the adjustment plate 2 and the adjustment threaded rod, thereby ensuring that the control elements in the drawer work normally without interfering with each other and improving the space utilization rate.

[0024] Second, the present invention cooperates with the limit rod, the slide plate and the displacement plate to make the three rubber plugs approach the vent until they are inserted into the vent, thereby completing the blocking of the vent and preventing rain from entering from the vent. At the same time, the three rubber plugs will also self-deflect during the process of displacement and insertion. This method can make the resistance encountered when blocking the vent smaller, make insertion more convenient, achieve better blocking effect, and make the structure safer and convenient for long-term use.

[0025] At the same time, compared with some traditional methods of directly using baffles to block the ventilation area, this measure is more effective in preventing rain and will not cause water stains to flow down from the gap between the baffle and the vent in the traditional way. It is more practical.

[0026] 3. The present invention cooperates with the fixed block, the pressing rod and the triangular tooth groove structure, so that the dustproof net is deflected when the displacement plate approaches the vent, so that the dustproof surface of the dustproof net is transformed into the rain-facing surface, so that the dust accumulated on the dustproof net on sunny days can be washed away by rainwater, and the dustproof net is self-cleaned, which is convenient for reuse and prevents external dust from entering the body from the vent to affect the safety of the line;

[0027] At the same time, when the dust-proof surface of the dust-proof net is transformed into the rain-facing surface, the dust-proof net vibrates. This measure can shake off the raindrops remaining on the dust-proof net due to its mesh-like characteristics, and prevent them from gathering at the air inlet of the vent.

[0028] Taking the above measures at the same time, when the dust-proof surface of the dust-proof net is turned into the rain-facing surface, the dust-proof net will not vibrate because dust is gathered on the dust-proof net at this time, making the structure more practical and dust will not enter from the vents that have not been completely blocked.

[0029] Fourth, the present invention cooperates with the structures such as the rotating shaft, the vibration spring and the spur cylinder to enable the vibration plate and the rubber plug to move back and forth, so that the rubber plug can seal the vent more smoothly, the structural strength of the connecting part is further reduced, and the sealing effect is further improved.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For example, see Figures 1 to 9 The present invention provides a space-adjustable low-voltage drawable switch cabinet, comprising a body 1, nine vents 2 are provided on the surface of the body 1, nine sets of mounting seats 3 are fixedly connected to the inner wall of the body 1, and drawers 4 are slidably connected to the inner walls of the nine sets of mounting seats 3, and adjustment components are provided in the nine drawers 4;

[0042] The surface of the body 1 is hinged with three groups of dustproof nets 5, the body 1 is provided with nine rubber plugs 6, the body 1 is provided with three groups of auxiliary components, the surface of the body 1 is fixedly connected with two shells 7, and the two shells 7 are provided with driving components;

[0043] The auxiliary components include a plugging component, and the low-voltage withdrawable switch cabinet also includes a self-cleaning component and a vibration component. The self-cleaning component is transmission-connected with the plugging component, and the vibration component is arranged on three groups of plugging components.

[0044] When the air inlet 2 is in the airtight state, the dust in the air passing through the air vent 2 is blocked, thereby preventing the dust from entering the main body 1 from the air vent 2. When the air inlet 2 is in the airtight state, the dust in the airtight state can be blocked by the dust net 5. When the air inlet 2 is in the airtight state, the dust in the airtight state can be blocked by the dust net 5.

[0045] When the rubber plug 6 performs the above-mentioned movement, the vibration component can be started to operate, so that the rubber plug 6 vibrates, so that it fills the vent 2 more densely, and the sealing effect is further improved.

[0046] See also Figures 1 to 4 The adjusting component includes an adjusting plate 1 8 and an adjusting plate 2 9. The adjusting plate 2 9 is fixedly connected to the inner wall of the drawer 4. The adjusting plate 1 8 is slidingly connected to the inner wall of the drawer 4. The inner wall of the adjusting plate 2 9 is rotatably connected with an adjusting threaded rod 10. The rod wall of the adjusting threaded rod 10 is threadedly connected to the inner wall of the adjusting plate 1 8. The rod wall of the adjusting threaded rod 10 is rotatably connected to the inner wall of the drawer 4.

[0047] In this embodiment, the adjusting threaded rod 10 can be rotated to make the adjusting plate 1 8 slide along the inner wall of the drawer 4, thereby changing the position between the adjusting plate 1 8 and the adjusting plate 2 9. This can ensure that the control elements in the drawer 4 work normally without interfering with each other, thereby improving the space utilization rate.

[0048] See also Figures 2 to 7The blocking component includes two limit rods 11, which are fixedly connected to the inner walls of the two shells 7 respectively, the rod walls of the two limit rods 11 are slidably connected with sliders 12, the inner walls of the two sliders 12 are rotatably connected with fixed shafts 13, the inner walls of the two shells 7 are slidably connected with slide plates 14, the surfaces of the two slide plates 14 are provided with a slide groove 1 for displacement of the fixed shaft 13, the shaft arms of the two fixed shafts 13 are rotatably connected with a displacement rod 15, and the surface of the body 1 is provided with a slide groove 2 for displacement of the displacement rod 15. The inner wall of the body 1 is slidably connected with two pressure rods 16, the rod walls of the two pressure rods 16 are jointly fixedly connected with a displacement plate 17, the inner wall of the displacement plate 17 is slidably connected with the rod wall of the displacement rod 15, the rod wall of the displacement rod 15 is fixedly connected with a rack row 18, the inner wall of the displacement plate 17 is rotatably connected with three rotating shafts 19, the shaft arms of the three rotating shafts 19 are fixedly connected with gears 20, and the three rubber stoppers 6 are respectively fixedly connected to the shaft arms of the three rotating shafts 19.

[0049] In this embodiment, the sliding plate 14 can be moved to drive the fixed shaft 13 to move synchronously. At this time, the fixed shaft 13 slides along the slide groove 1 on the sliding plate 14, that is, the sliding block 12 is displaced along the rod wall of the limiting rod 11, and then the displacement rod 15 is synchronously driven to move. In the process of displacement of the displacement rod 15, it also slides relatively with the body 1. Through the displacement of the displacement rod 15, the displacement plate 17 can be pushed to approach the direction of the vent 2. This process is limited by the pressing rod 16. In this way, the displacement plate 17 can drive the rack row 18, the three rotating shafts 19 and the gear 20 to approach the direction of the vent 2 synchronously, and then the three rubber plugs 6 can be approached to the direction of the vent 2 until they are inserted into the vent 2, thereby completing the blocking of the vent 2 and preventing external rainwater from entering from the vent 2.

[0050] In the above process, since the displacement rod 15 also slides relative to the body 1, the three gears 20 can be rotated by the rack row 18, so that the three rubber plugs 6 can be self-deflected during the displacement and insertion process through the transmission of the three rotating shafts 19. This method can make it less resistant when blocking the vent 2, making insertion more convenient, the structure safer, and convenient for long-term use;

[0051] At the same time, compared with some traditional methods of directly using baffles to block the ventilation area, this measure is more effective in preventing rain and will not cause water stains to flow down from the gap between the baffle and the vent in the traditional way. It is more practical.

[0052] See also Figures 2 to 8The self-cleaning component includes four fixed blocks 21, which are fixedly connected to the inner wall of the body 1, and the inner walls of the four fixed blocks 21 are fixedly connected with springs 22. The ends of the four springs 22 are fixedly connected with elastic plates 23. The surfaces of the four elastic plates 23 are respectively slidably connected to the inner walls of the four fixed blocks 21. The rod walls of the two pressure rods 16 are respectively provided with two groups of triangular tooth grooves 24. The ends of the four elastic plates 23 are respectively fitted with the groove walls of the four groups of triangular tooth grooves 24. The ends of the two pressure rods 16 are rotatably connected to the side walls of the dustproof net 5.

[0053] In this embodiment, when the displacement plate 17 approaches the vent 2, the pressure rod 16 is pushed to move synchronously. At this time, the dustproof net 5 can be pushed to deflect by the displacement of the pressure rod 16, so that the dustproof surface of the dustproof net 5 is transformed into the rain-facing surface. In this way, the dust accumulated on the dustproof net 5 on sunny days can be washed away by rainwater, and the dustproof net 5 is self-cleaned, which is convenient for reuse, and prevents external dust from entering the inside of the body 1 from the vent 2 to affect the safety of the line.

[0054] At the same time, during the displacement of the above-mentioned pressure rod 16, the triangular tooth groove 24 thereon will be displaced synchronously, and when the dustproof surface of the dustproof net 5 is pushed to be converted into the rain-facing surface, the end of the elastic plate 23 cooperates with the inclined surface of the triangular tooth groove 24. At this time, the displacement of the triangular tooth groove 24 will only cause the elastic plate 23 to press the spring 22, and this is repeated with the displacement of the pressure rod 16. When resetting to convert the rain-facing surface of the dustproof net 5 into the dustproof surface, the end of the elastic plate 23 cooperates with the straight edge of the triangular tooth groove 24. At this time, with the displacement of the pressure rod 16, the elastic plate 23 will be elastically deformed until it is separated from the straight edge and quickly hits the adjacent straight edge on the triangular tooth groove 24. In this way, the triangular tooth groove 24 can produce intermittent vibration in this process, and then the dustproof net 5 can be vibrated during the resetting process. This measure can shake off the raindrops remaining on the dustproof net 5 due to its mesh-like characteristics, and prevent them from gathering at the air inlet of the vent 2;

[0055] By taking the above measures at the same time, when the dustproof surface of the dustproof net 5 is transformed into the rain-facing surface, since dust is gathered on the dustproof net 5 at this time, the dustproof net 5 will not vibrate by utilizing the characteristics of the triangular tooth grooves 24, making the structure more practical and preventing dust from entering through the vent 2 that has not been completely blocked.

[0056] It is worth noting that the end of the elastic plate 23 is a spherical metal ball head.

[0057] Embodiment 2, based on the above embodiment:

[0058] See also Figures 5 to 9The vibration component includes a vibration shell 25, which is fixedly connected to the surface of the displacement plate 17. The ends of the three rotating shafts 19 are rotatably connected to the surface of the vibration shell 25. The shaft arms of the three rotating shafts 19 are rotatably connected to the vibration shafts 26. The shaft arms of the three vibration shafts 26 are slidably connected to the inner wall of the vibration shell 25. The ends of the three vibration shafts 26 are commonly fixedly connected to a tooth block plate 27. The shaft arms of the three vibration shafts 26 are all sleeved with vibration springs 28. The ends of the three vibration springs 28 are fixedly connected to the side walls of the tooth block plate 27. The inner wall of the vibration shell 25 is fixedly connected to a motor 29. The output end of the motor 29 is fixedly connected to a spur cylinder 30. The teeth of the spur cylinder 30 are meshed with the teeth of the tooth block plate 27. The ends of the three vibration shafts 26 are fixedly connected to vibration plates 31. The three vibration plates 31 are respectively located in three rubber stoppers 6.

[0059] In this embodiment, the motor 29 can be started to rotate the spur cylinder 30, so that the tooth plate 27 can be pushed to move under the limit of the vibration shell 25, so that the vibration spring 28 is compressed, and then the vibration shaft 26 is axially displaced. When the teeth of the tooth plate 27 are disengaged from the teeth of the spur cylinder 30, the tooth plate 27 can be quickly reset and re-engaged with the teeth of the spur cylinder 30 under the elastic reset of the vibration spring 28, so that the vibration shaft 26 can be moved back and forth in the axial direction, and then the vibration plate 31 and the rubber plug 6 can be moved back and forth, so that the rubber plug 6 can be more smoothly when blocking the vent 2, the structural strength of the connecting part is further reduced, and the blocking effect is further improved.

[0060] See also Figures 1 to 5 The driving component in the first embodiment is disclosed as follows: the driving component includes a driving motor 32, the driving motor 32 is fixedly connected to the inner wall of the shell 7, the output end of the driving motor 32 is fixedly connected to a driving threaded rod 33, the rod wall of the driving threaded rod 33 is threadedly connected to a driving plate 34, both ends of the driving plate 34 are slidably connected to the inner wall of the shell 7, and the surface of the driving plate 34 is fixedly connected to the side walls of the three slides 14.

[0061] In this embodiment, the driving motor 32 can be started to rotate the driving threaded rod 33, so that the driving plate 34 can be displaced under the limit of the shell 7, thereby pushing the three slide plates 14 to be displaced.

[0062] Embodiment 3, based on the above embodiment:

[0063] See also Figure 1 The surfaces of the nine drawers 4 are all fixedly connected with handles 35, and the surfaces of the nine handles 35 are all provided with anti-skid patterns. By setting the handles 35, the drawers 4 can be conveniently controlled, and by providing the anti-skid patterns, the operator can avoid slipping when holding the drawers.

[0064] See also Figure 1 The surface of the main body 1 is fixedly connected with a mounting frame 36, and the mounting frame 36 is made of L-shaped steel. Through the setting of the mounting frame 36, the main body 1 can be conveniently installed at any position outdoors, which is more convenient when the device is initially set up.

[0065] Working principle: When the space-adjustable low-voltage withdrawable switch cabinet is in use, the driving motor 32 can be started to make the three rubber plugs 6 deflect and move at the same time, so as to approach the direction of the vent 2 until the vent 2 is efficiently and comprehensively blocked to prevent rainwater from entering from here. At the same time, the dustproof net 5 will also be deflected, so that the windward side of the dustproof net 5 is turned into the rain-facing side, so that the dust intercepted on the dustproof net 5 can be washed away by rainwater. After waiting for the rain to stop, the clean dustproof net 5 can be reversed to cooperate with the vent 2 in the ventilation state. After the rubber plug 6 completes the above-mentioned movement, the motor 29 can be started to make the vibration plate 31 and the rubber plug 6 move back and forth. In this way, the rubber plug 6 can be smoother in sealing the vent 2, the structural strength of the connecting part is further reduced, and the sealing effect is further improved.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
