Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet dehumidification component and a power distribution cabinet. Background Art

[0002] As an important part of the power system, the normal operation of the distribution cabinet is crucial to the stability and reliability of power supply. Since the distribution cabinet is in a closed state for a long time, if the humidity inside is too high and cannot be dehumidified, it is easy to cause internal components to get damp, insulation performance to deteriorate, and short circuits and other adverse effects, and even cause fires. Therefore, it is necessary to dehumidify the interior of the distribution cabinet in time to ensure that it is dry inside.

[0003] However, at present, when dehumidifying the distribution cabinet, an exhaust fan is usually used to exhaust the air inside the distribution cabinet, but the dehumidification effect is not good, and the inside of the distribution cabinet cannot be dehumidified quickly. With the development of science and technology, technical personnel in related fields have also carried out a lot of optimization on the dehumidification of the distribution cabinet. In order to make a more accurate comparison, a Chinese patent with publication number CN115364633A discloses a distribution cabinet dehumidification device and a distribution cabinet, including a containing box, a supply unit and a recovery unit. The containing box includes a mesh structure, and a plurality of adsorption balls are arranged in the containing box. The supply unit includes a guide cylinder and a pushing mechanism. The pushing mechanism can push the adsorption balls in the guide cylinder into the containing box, and the recovery unit can dry the adsorption balls in the containing box and transport them to the guide cylinder.

[0004] When the above-mentioned prior art is in use, the adsorption balls are ejected into the storage box through the supply unit. The irregular collision of the adsorption balls in the storage box can fully absorb the water vapor in the distribution cabinet, thereby keeping the distribution cabinet dry. The water vapor adsorbed by the adsorption balls can be heated and dried through the recovery unit, and then the adsorption balls are transported to the supply unit to achieve repeated use of the adsorption balls.

[0005] However, the above-mentioned prior art still has some shortcomings in the process of dehumidifying the inside of the power distribution cabinet: 1. Since the adsorption ball can only absorb water vapor in the storage box, its dehumidification range is limited. It cannot fully dehumidify the inside of the distribution cabinet and the components. There are dead corners, which makes it impossible to reduce the humidity in the space outside the storage box. The components are still susceptible to moisture, thus affecting the dehumidification effect.

[0006] 2. Although the adsorption balls can be repeatedly used to adsorb water vapor inside the distribution cabinet, when the adsorption balls enter the storage box again after being heated and dried, the adsorption balls will heat the air in the distribution cabinet through the heat of their bodies, causing the water vapor in the air to evaporate and rise to the top of the distribution cabinet. However, the above-mentioned prior art cannot discharge the heated air in the distribution cabinet, which causes the rising water vapor to condense into water on the top wall of the distribution cabinet. Therefore, it not only affects the dehumidification effect, but also causes water droplets to fall on components, causing short circuits and safety hazards.

[0007] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing dehumidification methods of distribution cabinets. Summary of the invention

[0015] As a preferred technical solution of the present invention, the linkage part includes a transmission bevel gear, and the outer wall of the transmission shaft is sleeved with multiple transmission bevel gears corresponding to the positions of the dehumidification fans.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 12 Embodiments of the present invention are described in detail.

[0036] The embodiment of the present application discloses a distribution cabinet dehumidification component and a distribution cabinet. It should be noted that the present application is mainly used in the process of dehumidifying the distribution cabinet. In terms of technical effect, it can monitor the humidity inside the distribution cabinet in real time, and can adaptively dehumidify according to the humidity conditions, which can effectively save energy. The dehumidification fan 53 cooperates with the horizontal cylinder 51 to blow air into the distribution cabinet in an internal circulation manner, and the air inside the distribution cabinet is sucked into the horizontal cylinder 51 for drying, thereby achieving dehumidification inside the distribution cabinet to ensure the dryness inside the distribution cabinet; especially when the dehumidification fan 53 blows air into the distribution cabinet, it can It is capable of heating the air inside the horizontal cylinder 51, so that the dehumidification fan 53 blows out the hot air to fully dehumidify the interior of the distribution cabinet, and the air can be dehumidified when entering the horizontal cylinder 51 and the hot air inside the horizontal cylinder 51 is blown out, thereby enhancing the dehumidification effect; further, the present application can also control the reciprocating swing of the dehumidification fan 53 to change the blowing direction of the dehumidification fan 53, which can increase the dehumidification range of the dehumidification fan 53 inside the distribution cabinet, thereby achieving comprehensive dehumidification of the interior of the distribution cabinet and its internal equipment and components, thereby further enhancing the dehumidification effect inside the distribution cabinet. Embodiment 1:

[0037] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the first aspect, the present invention provides a dehumidification component for a distribution cabinet, which is applied to a distribution cabinet, and includes two vertical brackets 4 respectively installed on the inner walls on both sides of the width direction of the cabinet body 1, and a dehumidification mechanism 5 is arranged on the opposite sides of the two vertical brackets 4. The dehumidification mechanism 5 includes a horizontal cylinder 51 installed between the two vertical brackets 4, and a dehumidification fan 53 is arranged on the horizontal cylinder 51. A heating branch chain 52 for drying moisture in the air is installed inside the horizontal cylinder 51. The dehumidification mechanism 5 also includes a control branch chain 54 for controlling the dehumidification fan 53 to move to the middle of the cabinet body 1, and the control branch chain 54 includes a mounting plate 541 installed at both ends of the horizontal cylinder 51 and slidably arranged on the opposite sides of the two vertical brackets 4.

[0038] During the specific implementation process, when the cabinet door 2 is closed, the interior of the distribution cabinet is in a closed state. At this time, the horizontal cylinder 51 and the dehumidification fan 53 are controlled by controlling the branch chain 54 to move down to the middle of the cabinet 1 as a whole. Then, the dehumidification fan 53 is operated to blow the air inside the horizontal cylinder 51 to the interior of the distribution cabinet and suck the air in the cabinet 1 into the horizontal cylinder 51. The air inside the horizontal cylinder 51 is heated by the heating branch chain 52 to dry the moisture therein, thereby realizing the internal circulation of the air in the cabinet 1, and being able to dry the moisture in the air in the cabinet 1, thereby effectively reducing the humidity inside the distribution cabinet.

[0039] Reference Figure 2 , Figure 3 and Figure 4As shown, in order to prevent the horizontal cylinder 51 from interfering with the maintenance personnel in operating or maintaining the internal equipment of the power distribution cabinet, a control branch chain 54 is provided in this embodiment for controlling the adaptive up and down movement of the horizontal cylinder 51 and the dehumidification fan 53. Specifically, the control branch chain 54 also includes a vertical slide groove, and vertical slide grooves are provided on the opposite sides of the two vertical brackets 4. The mounting plate 541 is slidably docked in the vertical slide groove through the supporting block 542. A pull rope 543 is installed on the upper ends of the two supporting blocks 542. The end of the pull rope 543 away from the supporting block 542 passes upward through the vertical bracket 4 and the cabinet body 1 in turn and is connected to the cabinet door 2. A counterweight block 544 is provided at the lower end of the supporting block 542.

[0040] Furthermore, in this embodiment, a connecting block 545 is installed on the side of the cabinet door 2 opposite to the cabinet body 1, and the connecting block 545 is located on the side of the middle of the cabinet door 2 away from the connection between it and the cabinet body 1. The ends of the two pull ropes 543 away from the supporting block 542 are both passed through the side of the cabinet body 1 away from the connection between it and the cabinet door 2 and are connected to the connecting block 545. It should be noted that the two pull ropes 543 have different lengths, but when the two pull ropes 543 are subjected to tension, they can pull the supporting blocks 542 at their ends upward to the same height.

[0041] In the specific implementation process, when the cabinet door 2 is opened, the cabinet door 2 applies a pulling force to the pull rope 543 through the connecting block 545, so that the pull rope 543 drives the mounting plate 541, the horizontal cylinder 51 and the dehumidification fan 53 to move to the highest position as a whole (at Figure 2 ), thereby preventing the horizontal cylinder 51 from affecting the operation or maintenance of the equipment inside the distribution cabinet by maintenance personnel; when the cabinet door 2 is closed, the cabinet door 2 no longer applies tension to the pull rope 543, so that the supporting block 542 drives the horizontal cylinder 51 and the dehumidification fan 53 to move down to the middle position of the cabinet body 1 as a whole under the action of the counterweight block 544, so that when the dehumidification fan 53 blows air into the distribution cabinet, it can ensure that the internal space is affected by the blowing effect, so that balanced dehumidification can be achieved, and then the interior of the distribution cabinet can be fully dehumidified, effectively preventing the dehumidification fan 53 from being too high or too low and affecting the dehumidification effect inside the distribution cabinet.

[0042] Reference Figure 6 As shown, in order to effectively remove moisture from the air during the internal air circulation of the distribution cabinet to ensure the dryness inside the distribution cabinet, based on this, in the present embodiment, a heating branch chain 52 is provided. Specifically, the heating branch chain 52 includes a through hole 521 opened on the upper and lower sides of the horizontal cylinder 51, and the upper and lower side walls of the horizontal cylinder 51 are both equipped with a plurality of air inlet scoops 522 covered on the outside of the through hole 521, and the upper and lower inner walls of the horizontal cylinder 51 are both equipped with supporting mesh plates 523, and the opposite sides of the two supporting mesh plates 523 are respectively provided with electric heating plates 524 and heat-resistant filter pads 525, and the heat-resistant filter pads 525 are abutted against the inner wall of the horizontal cylinder 51 and block the through hole 521.

[0043] It should be noted that, on both vertical side walls of the horizontal cylinder 51, there are installed multiple dehumidification fans 53 which are evenly distributed along its length direction, and a sealing frame 531 is arranged between the dehumidification fan 53 and the horizontal cylinder 51; the sealing frame 531 can compensate for the gap between the dehumidification fan 53 and the horizontal cylinder 51 to prevent air from being discharged from the gap and affecting the blowing effect of the dehumidification fan 53.

[0044] During the specific implementation process, when the dehumidification fan 53 blows air into the distribution cabinet, the air in the horizontal cylinder 51 is extracted, so that a negative pressure is generated inside the horizontal cylinder 51, and the air inside the distribution cabinet passes through the air inlet hopper 522 and the through hole 521 and enters the horizontal cylinder 51; at the same time, the electric heating plate 524 is started, and the electric heating plate 524 heats the air in the horizontal cylinder 51 so as to heat and dry the moisture in the air, and then the dehumidification fan 53 can further heat and dry the moisture in the air inside the distribution cabinet when blowing out the hot air.

[0045] When the air inside the distribution cabinet enters the horizontal cylinder 51, it first passes through the heat-resistant filter pad 525, so that the heat-resistant filter pad 525 can initially filter out the moisture in the air. Then, when the air passes through the electric heating plate 524, the moisture can be further removed. In this way, it can play a dehumidifying role when the air enters the horizontal cylinder 51 and the hot air inside the horizontal cylinder 51 is blown out, thereby enhancing the dehumidification effect inside the distribution cabinet.

[0046] It should be noted that the electric heating plate 524 used in this embodiment is only used to heat the air, and the heat it generates is no more than 30 degrees Celsius, so it cannot have any adverse effects on the components and equipment inside the distribution cabinet; in addition, in hot summer weather, the outdoor temperature is higher than the internal temperature of the distribution cabinet. In order to ensure the normal operation of the internal equipment and components of the distribution cabinet, the internal temperature of the distribution cabinet should not be too high. At this time, turn off the electric heating plate 524, and only use the heat-resistant filter pad 525 to remove moisture from the air entering the horizontal cylinder 51.

[0047] Reference Figure 5 , Figure 7 and Figure 8 As shown, in order to save energy, in this embodiment, the dehumidification fan 53 can be controlled to perform dehumidification only when the humidity inside the distribution cabinet is high. Based on this, in this embodiment, the dehumidification mechanism 5 also includes a drive branch chain 55 for controlling the operation of the dehumidification fan 53. The drive branch chain 55 includes a hygrometer 551 and a controller 552 installed at the upper end of the horizontal cylinder 51. The hygrometer 551 and the controller 552 are electrically connected, and the controller 552 and the electric heating plate 524 are electrically connected.

[0048] Furthermore, in this embodiment, the driving branch chain 55 also includes a positioning motor 553 installed on any inner wall in the length direction of the horizontal cylinder 51 through a motor seat, and the output shaft of the positioning motor 553 is installed with a transmission shaft 554, and a linkage 555 is arranged between the transmission shaft 554 and the dehumidification fan 53.

[0049] It should be noted that the hygrometer 551 controller 552 used in this embodiment is a prior art, which is mainly used to receive the humidity signal of the hygrometer 551 and transmit the start and stop signals to the electric heating plate 524 and the positioning motor 553, which will not be repeated here.

[0050] Furthermore, in order to facilitate the operation of the dehumidification fan 53 within the specified time, in the present embodiment, the linkage 555 includes a transmission bevel gear 556, and the outer wall of the transmission shaft 554 is provided with a plurality of transmission bevel gears 556 corresponding to the position of the dehumidification fan 53, and the inner walls on both sides of the horizontal cylinder 51 on which the dehumidification fan 53 is installed are provided with fixing frames 557, and a positioning shaft 558 is rotatably provided on the fixing frame 557, and the end of the positioning shaft 558 is provided with an auxiliary bevel gear 559 meshing with the transmission bevel gear 556, and the end of the positioning shaft 558 away from the auxiliary bevel gear 559 is connected to the rotating shaft in the middle of the dehumidification fan 53.

[0051] During the specific implementation process, when the cabinet door 2 is in a closed state, the hygrometer 551 is started, and the humidity inside the distribution cabinet is monitored in real time through the hygrometer 551. When the humidity inside the distribution cabinet is high, the hygrometer 551 transmits a signal to the controller 552, and the controller 552 controls the electric heating plate 524 and the positioning motor 553 to be energized, so that the electric heating plate 524 heats and dries the air inside the horizontal cylinder 51. At the same time, the positioning motor 553 drives the transmission shaft 554 and the transmission bevel gear 556 to rotate, and the transmission bevel gear 556 drives the rotating shaft in the middle of the dehumidification fan 53 to rotate through the auxiliary bevel gear 559, thereby realizing the automatic operation of the dehumidification fan 53 to automatically dehumidify the inside of the distribution cabinet.

[0052] When the humidity inside the distribution cabinet drops to a standard, the controller 552 controls the electric heating plate 524 and the positioning motor 553 to cut off the power, so that the dehumidification fan 53 stops running, thereby effectively saving energy and being able to adaptively dehumidify according to the humidity inside the distribution cabinet.

[0053] Reference Fig. 9As shown, in the second aspect, the present invention further provides a power distribution cabinet, comprising a cabinet body 1 and a cabinet door 2 hinged to each other by hinges, and the outer wall at the connection between the cabinet body 1 and the cabinet door 2 is jointly provided with a plurality of self-locking mechanisms 3 equidistantly distributed from top to bottom. It should be noted that the self-locking mechanism 3 adopted in this embodiment is an existing technology for locking the cabinet door 2 after opening to prevent rebound, which will not be repeated here. Through the setting of the self-locking mechanism 3, the cabinet door 2 can be limited after opening to prevent it from rebounding at will and affecting the normal work of the maintenance personnel. Embodiment 2:

[0054] Reference Fig.10 , Fig.11 and Fig.12 As shown, on the basis of the first embodiment, in order to further enhance the dehumidification effect inside the power distribution cabinet, based on this, in this embodiment, the dehumidification fan 53 can be controlled to reciprocate when blowing out the hot air, so as to increase the blowing area of ​​the dehumidification fan 53. Specifically, a corresponding swing mechanism 6 is provided in this embodiment, and the swing mechanism 6 is specifically as follows: The swing mechanism 6 includes a plurality of sleeves 61 sleeved on the outer wall of the transmission shaft 554, and the plurality of sleeves 61 are arranged at intervals with the plurality of dehumidification fans 53. The outer wall of the sleeve 61 is provided with two groups of threads that are interconnected and rotate in opposite directions. The outer wall of the sleeve 61 is sleeved with a reciprocating ring 62 by means of a threaded connection. The fixed frame 557 is provided with a plurality of horizontal slide grooves 63 corresponding to the positions of the reciprocating ring 62. The outer wall of the reciprocating ring 62 is provided with two connecting rods 64 that slide through the horizontal slide grooves 63. The rotation direction of the reciprocating ring 62 can be limited by the connecting rods 64 and the horizontal slide grooves 63, so that the reciprocating ring 62 can only move back and forth along the length direction of the horizontal slide grooves 63. A linkage plate 65 is installed at one end of the connecting rod 64 away from the reciprocating ring 62. Two control slide grooves 66 are symmetrically provided on the side of the linkage plate 65 away from the connecting rod 64, and the spacing between the two control slide grooves 66 on the same linkage plate 65 gradually increases from one side to the other.

[0055] Furthermore, in the present embodiment, cross bars 67 are installed on the upper and lower sides of the opposite sides of the two adjacent sealing frames 531 close to the linkage plate 65, and a telescopic rod 68 is provided on the side of the cross bar 67 close to the linkage plate 65. The end of the telescopic rod 68 close to the linkage plate 65 is rotatably connected to an ear seat 69 through a pin shaft. The ear seat 69 has an opening for accommodating the telescopic rod 68, and the opening passes through from top to bottom. A sliding rod 70 that is slidably docked in the control slide groove 66 is provided on the side of the ear seat 69 away from the telescopic rod 68.

[0056] Furthermore, in the present embodiment, the upper and lower sides of the sealing frame 531 are arc-shaped structures, and a support shaft 71 rotatably penetrated in the interior of the horizontal cylinder 51 is installed between two adjacent sealing frames 531 .

[0057] During the specific implementation process, the transmission shaft 554 drives the sleeve 61 to rotate synchronously during its rotation. The sleeve 61 drives the reciprocating ring 62 to move back and forth along the horizontal slide groove 63 through the threaded groove, so that the reciprocating ring 62 drives the linkage plate 65 to move synchronously. During this period, the telescopic rod 68 can be limited by the setting of the ear seat 69 and the opening, so that the ear seat 69 and the telescopic rod 68 can only rotate in the up and down directions, and cannot move along the vertical direction of the opening, that is, when the linkage plate 65 moves along the horizontal slide groove 63, the sliding rod 70 and the ear seat 69 can only move up and down, and cannot move synchronously with the linkage plate 65. At the same time, the telescopic rod 68 adaptively retracts and retracts and adaptively rotates with the ear seat 69.

[0058] The linkage plate 65 can drive the sliding rods 70 on its two adjacent sealing frames 531 to move up and down through the control slide groove 66, and the two sliding rods 70 on the same linkage plate 65 can move relative to each other or move away from each other synchronously under the action of the control slide groove 66, so that the sliding rod 70 drives the ear seat 69, the telescopic rod 68 and the cross bar 67 to move synchronously, so that the cross bar 67 drives the dehumidification fan 53 to rotate adaptively along the support shaft 71 through the sealing frame 531, thereby controlling the reciprocating swing of the dehumidification fan 53 to change the blowing direction of the dehumidification fan 53, which can increase the dehumidification range of the dehumidification fan 53 inside the distribution cabinet, and then achieve comprehensive dehumidification, thereby further enhancing the dehumidification effect inside the distribution cabinet.

[0059] It should be noted that, in the present embodiment, a ball bearing (not shown in the figure) is installed on the inner wall of the reciprocating ring 62 so as to roll and abut against the thread groove. The ball bearing can reduce the friction between the reciprocating ring 62 and the thread groove, so as to improve the smoothness of the reciprocating movement of the reciprocating ring 62 during the rotation of the sleeve 61. In addition, in order to ensure that the dehumidification fan 53 can operate normally during the smooth reciprocating swing along the support shaft 71, based on this, the side of the positioning shaft 558 close to the dehumidification fan 53 is a telescopic shaft 560, and the telescopic shaft 560 and the side of the positioning shaft 558 close to the auxiliary bevel gear 559 are connected by a universal coupling 561. Through the arrangement of the telescopic shaft 560 and the universal coupling 561, the auxiliary bevel gear 559 will not be affected or interfered by the reciprocating swing of the dehumidification fan 53, and during the swing of the dehumidification fan 53, the auxiliary bevel gear 559 can still drive the dehumidification fan 53 to operate normally through the universal coupling 561 and the telescopic shaft 560.

[0060] During operation: Step 1: When closing the cabinet door 2, the cabinet door 2 will not apply tension to the pull rope 543, so that the supporting block 542 drives the horizontal cylinder 51 and the dehumidification fan 53 to move down to the middle position of the cabinet body 1 under the action of the counterweight block 544, preventing the position of the dehumidification fan 53 from being too high or too low and affecting the dehumidification effect inside the distribution cabinet.

[0061] Step 2: When the cabinet door 2 is in the closed state, start the hygrometer 551, and monitor the humidity inside the distribution cabinet in real time through the hygrometer 551. When the humidity inside the distribution cabinet is high, the hygrometer 551 transmits a signal to the controller 552. The controller 552 controls the electric heating plate 524 and the positioning motor 553 to be energized, so that the electric heating plate 524 heats and dries the air inside the horizontal cylinder 51. At the same time, the positioning motor 553 drives the transmission shaft 554 and the transmission bevel gear 556 to rotate. The transmission bevel gear 556 drives the rotating shaft in the middle of the dehumidification fan 53 to rotate through the auxiliary bevel gear 559, thereby realizing the automatic operation of the dehumidification fan 53 to automatically dehumidify the inside of the distribution cabinet.

[0062] Step 3: When the dehumidification fan 53 blows air into the distribution cabinet, the air in the horizontal cylinder 51 is extracted, so that negative pressure is generated inside the horizontal cylinder 51, and the air inside the distribution cabinet enters the horizontal cylinder 51; at the same time, the electric heating plate 524 heats the air in the horizontal cylinder 51 to heat and dry the moisture in the air, and then the dehumidification fan 53 can further heat and dry the moisture in the air inside the distribution cabinet when blowing out the hot air.

[0063] When the air inside the distribution cabinet enters the horizontal cylinder 51, it first passes through the heat-resistant filter pad 525, so that the heat-resistant filter pad 525 can initially filter out the moisture in the air. Then, when the air passes through the electric heating plate 524, the moisture can be further removed. In this way, it can play a dehumidifying role when the air enters the horizontal cylinder 51 and the hot air inside the horizontal cylinder 51 is blown out, thereby enhancing the dehumidification effect inside the distribution cabinet.

[0064] Step 4: During the rotation of the transmission shaft 554, the sleeve 61 is driven to rotate synchronously, and the sleeve 61 drives the reciprocating ring 62 and the linkage plate 65 to move back and forth. The linkage plate 65 drives the sliding rods 70 on its two adjacent sealing frames 531 to move up and down through the control slide groove 66, and the two sliding rods 70 on the same linkage plate 65 move synchronously relative to each other or synchronously move opposite to each other under the action of the control slide groove 66, so that the sliding rod 70 drives the ear seat 69, the telescopic rod 68 and the cross bar 67 to move synchronously, so that the cross bar 67 drives the dehumidification fan 53 to rotate adaptively along the support shaft 71 through the sealing frame 531, so as to change the blowing direction of the dehumidification fan 53, which can increase the dehumidification range of the dehumidification fan 53 inside the distribution cabinet, and then achieve comprehensive dehumidification, thereby further enhancing the dehumidification effect inside the distribution cabinet.

[0065] Step 5: When the humidity inside the power distribution cabinet drops to the standard, the controller 552 controls the electric heating plate 524 and the positioning motor 553 to cut off the power, so that the dehumidification fan 53 stops running, thereby effectively saving energy and being able to adaptively dehumidify according to the humidity inside the power distribution cabinet.

[0066] Step 6: When the cabinet door 2 is opened, the cabinet door 2 applies tension to the pull rope 543 through the connecting block 545, so that the pull rope 543 drives the mounting plate 541, the horizontal cylinder 51 and the dehumidification fan 53 to move to the highest position as a whole through the supporting block 542, thereby preventing the horizontal cylinder 51 from affecting the maintenance personnel's operation or maintenance of the equipment inside the distribution cabinet.
