Description

Technical Field

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

[0002] A distribution box is generally an electrical equipment that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment as needed. Various devices in the distribution cabinet will generate a lot of heat during operation. In order to ensure the normal operation of the distribution cabinet, the existing technology often opens open heat dissipation holes on the side of the box for heat dissipation. The application places of distribution boxes are mostly in outdoor environments. Therefore, when the distribution cabinet performs heat dissipation work by exchanging internal and external air, outdoor air can enter the distribution box through the heat dissipation holes. The external air itself contains water vapor, which can easily cause moisture inside the distribution box, resulting in electrical short circuits and moisture accumulation in cable trenches. However, the distribution box in the existing technology lacks measures that take into account both heat dissipation and moisture-proofing. Therefore, it is impossible to ensure that the inside of the box remains dry and at a low temperature for a long time, thereby failing to ensure the safe use of the distribution box and thus failing to meet the use requirements. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the existing distribution box with a dehumidification structure, the present invention is proposed.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: a distribution box with a dehumidification structure, comprising a receiving unit and a dehumidification unit, wherein the receiving unit comprises two sets of symmetrically arranged side panels and a back panel arranged on one side of the side panels; A storage compartment is provided on the inner side of the side panel, and multiple sets of side exhaust pipes are provided inside the side panel, and the two ends of the side exhaust pipes are respectively connected to the outer side of the top end and the inner side of the bottom end of the side panel; The back panel is provided with a plurality of positive exhaust pipes, and the positive exhaust pipes are provided with a plurality of positive exhaust ports, and the positive exhaust ports penetrate the back panel and are connected to the storage compartment; The dehumidification unit includes a fixed component located at the top of the side plate, a dehumidification component disposed in the fixed component, a driving component disposed in the fixed component, and a plurality of partition components disposed below the driving component; The fixed component includes a fixed frame surrounding the dehumidification component, a side through groove opened on the fixed frame, and a connecting groove opened at the center of the fixed frame and connected to the fixed ring.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1 Reference Figures 1 to 4 , which is a first embodiment of the present invention, provides a distribution box with a dehumidification structure, including a receiving unit 100 and a dehumidification unit 200, wherein the receiving unit 100 includes two sets of symmetrically arranged side panels 101 and a back panel 104 arranged on one side of the side panels 101; A storage compartment 1011 is provided on the inner side of the side panel 101. Multiple sets of side exhaust ducts 1012 are provided inside the side panel 101, and the ends of the side exhaust ducts 1012 extend to the outer side of the top end and the inner side of the bottom end of the side panel 101, respectively. The storage compartment 1011 is located between the two sets of side panels 101, providing a place for installing electrical equipment. The side exhaust ducts 1012 are used to discharge air from the storage compartment 1011. Air enters through the air intake grille 103 and flows out through the side exhaust ducts 1012, allowing air to circulate between the interior and exterior of the storage unit 100, thereby achieving a heat dissipation effect. The back panel 104 has multiple sets of positive exhaust ducts 1041, and multiple positive exhaust ports 1042 are provided on the positive exhaust ducts 1041. The positive exhaust ports 1042 penetrate the back panel 104 and communicate with the storage compartment 1011. The positive exhaust ducts 1041 are provided inside the back panel 104, and their top ends communicate with the fixing member 201. The positive exhaust ports 1042 are evenly distributed on the positive exhaust ducts 1041, and their openings face inward and communicate with the storage compartment 1011. If air enters the positive exhaust ducts 1041, it can be discharged through the positive exhaust ports 1042 provided on the positive exhaust ducts 1041. The dehumidification unit 200 includes a fixed component 201 located at the top of the side panel 101, a dehumidification component 202 disposed in the fixed component 201, a driving component 203 disposed in the fixed component 201, and a plurality of partition components 205 disposed below the driving component 203; The fixed component 2011 includes a fixed frame 20111 that surrounds the dehumidification component 202, a side groove 20112 opened on the fixed frame 20111, and a connecting groove 20113 opened at the center of the fixed frame 20111 and connected to the fixed ring 2012. One side of the side groove 20112 is connected to the positive exhaust duct 1041. The dehumidification unit 200 as a whole is connected to the interior of the receiving unit 100. The fixed component 201 is non-fixedly connected to the top of the side plate 101. The dehumidification component 202 is arranged in the fixed component 201 with its opening downward. It absorbs external humid air and dehumidifies it, and then drives the air flow in the box by blowing. The driving component 203 can cut off the connection between the dehumidification unit 200 as a whole and the receiving unit 100.

[0031] During use, one side of the fixing part 201 is communicated with the inside of the back panel 104. When the cabinet door 102 is closed and abutted against the side of the side panel 101, the partition component 205 expands outward, and the dehumidification unit 200 is communicated with the receiving unit 100 as a whole. Then the dehumidification component 202 will inhale the external humid air through the air intake grille 103, and then absorb the water vapor in the air and blow the no longer humid air downward to the receiving unit 100. By accelerating the air flow, the components inside the device are cooled. When the cabinet door 102 is opened, the partition component 205 is gathered inward. The vertical connection between the dehumidification unit 200 and the receiving unit 100 is cut off. At this time, the airflow blown out by the dehumidification component 202 will be transported into the back panel 104 through the side of the fixing component 201, and blown out from the side of the side panel 101 through the back panel 104. The direction of the airflow at this time is from the back panel 104 to the notch of the receiving unit 100 where the cabinet door 102 is rotated to open. The method of blowing toward the notch can prevent the external moist air that has not been dehumidified from entering the interior of the device, further preventing the moist air from corroding the components in the device and ensuring the safe use of the device.

[0032] Among them, reference Figure 2 The storage unit 100 further includes a cabinet door 102 disposed on one side of the side panel 101, and an air intake grille 103 disposed on the side panel 101 and located at the top end on the same side of the cabinet door 102. The cabinet door 102 and the back panel 104 are symmetrically disposed on either side of the side panel 101. The two sets of symmetrically disposed side panels 101 cooperate with each other to form a complete cabinet. One side of the cabinet door 102 is rotatably connected to the side panel 101. The air intake grille 103 has multiple air flow channels for circulating air within the device. A connecting block 1021 is disposed on the inner side of the cabinet door 102.

[0033] Further, refer to Figure 3 The side exhaust duct 1012 includes an exhaust pipe 10121 located inside the side panel 101 and arranged vertically, an internal interface 10122 arranged at the bottom end of the exhaust pipe 10121 and opening inward to communicate with the storage bin 1011, and an external interface 10123 arranged at the top end of the exhaust pipe 10121 and opening outward to communicate with the outside. The position of the external interface 10123 is relatively high because under normal circumstances, moisture is usually in a position close to the ground in the air. Because moisture is saturated with water, its density is greater than that of air without moisture, so it will be relatively close to the ground. The higher position of the external interface 10123 can effectively prevent moisture from low places from entering the interior of the device, further ensuring the safety of the device.

[0034] During use, when the driving component 203 blows the dehumidified air from the top of the storage bin 1011 downward, the blown air will take away the heat generated by the components in the device, and be transported and discharged to the outside of the storage unit 100 through the internal interface 10122 at the bottom, thereby playing a certain heat dissipation role. The external interface 10123 is set at a higher position on the side panel 101, and the air discharged from the device can be placed at a higher position. At this time, the discharged air has undergone a dehumidification treatment, and its humidity is much lower than the air that has not been dehumidified. In the process of going out to the outside, the contact between the hot air it contains and the outside will gradually decrease. At the same time, the air at a higher position is closer to the dehumidification unit 200, and will be absorbed and transported into the device first, continuing the work of circulating air inside and outside the device.

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 2 Reference Figures 5 to 13 , which is the second embodiment of the present invention. This embodiment is different from the second embodiment in that the direction of the air flow inside the switching device is obtained, and external moisture can be prevented from entering the interior of the device when the device is closed or open.

[0037] Compared with Example 2, further, referring to Figure 7 The dehumidification unit 200 also includes a reset component 204 arranged above the driving component 203, a bearing component 206 arranged below the partition component 205, and a connecting rope 207 connected between the driving component 203 and the cabinet door 102 and passing through one side of the bearing component 206. One end of the connecting rope 207 is connected to the connecting block 1021 on the inner side of the cabinet door 102, and the other end is connected to the driving component 203. The two ends of the reset component 204 are respectively fixedly connected to the driving component 203 and the bearing component 206, and can drive the driving component 203 to rotate by contraction or expansion.

[0038] Among them, reference Figure 10 The fixing component 201 includes a fixing assembly 2011 located at the top of the side panel 101, within which the dehumidifying assembly 202 is mounted, and a fixing ring 2012 disposed below the fixing assembly 2011. The fixing assembly 2011 is used to mount and secure the dehumidifying assembly 202. The fixing ring 2012 is fixedly disposed below the fixing assembly 2011 and has a circular ring structure. The driving component 203 is sleeved on the fixing ring 2012.

[0039] Further, refer to Figure 10The fixed component 2011 includes a fixed frame 20111 that surrounds the dehumidification component 202, a side groove 20112 opened on the fixed frame 20111, and a connecting groove 20113 opened at the center of the fixed frame 20111 and connected to the fixed ring 2012. One side of the side groove 20112 is connected to the positive exhaust duct 1041, and the air flowing through the side groove 20112 can flow downward through the positive exhaust duct 1041.

[0040] Among them, reference Figure 7 The dehumidification component 202 includes a dehumidifier 2021 located in the fixed component 2011, and an exhaust fan 2022 arranged below the dehumidifier 2021. The dehumidifier 2021 is a device for removing moisture from the air and is a more common dehumidification device in the prior art. The exhaust fan 2022 is arranged below the dehumidifier 2021. It can roll up the air after dehumidification by the dehumidifier 2021 and transport it into the interior of the housing unit 100, thereby cooling the components installed inside the housing unit 100.

[0041] Among them, reference Figure 12 The driving component 203 includes a driving component 2031 located below the fixing component 2011, and a connecting component 2032 disposed above the driving component 2031 and sleeved on the outer side of the fixing ring 2012. The driving component 2031 and the connecting component 2032 are fixedly connected, and both are circular ring structures, with a central hollow groove communicating with the fixing component 201.

[0042] Further, refer to Figure 13 The driving component 2031 includes a circular driving plate 20311 and a plurality of driving grooves 20312 arranged on the driving plate 20311, and the top of the partition component 205 extends into the driving groove 20312. The driving groove 20312 is an arc-shaped structure as a whole, and its two ends are respectively located at the center position of the driving plate 20311 and the outer circle position surrounding the driving plate 20311.

[0043] Further, refer to Figure 13 The connecting component 2032 includes a connecting ring 20321 fixedly connected to the driving component 2031, and a connecting ear 20322 fixedly arranged on the outer edge of the connecting ring 20321, and one end of the connecting rope 207 is fixedly connected to the connecting ear 20322. In the initial state, the connecting rope 207 will be wound around the connecting ring 20321.

[0044] During use, when the device as a whole is in a closed state, the four groups of partition components 205 are in a dispersed state of outward expansion below the driving component 2031, and the end of the partition component 205 is located at the end of the driving groove 20312 close to the outside. When the driving component 203 rotates as a whole and the partition component 205 is limited and fixed by the supporting component 206, the position of the driving groove 20312 gradually changes, and the outer end of the partition component 205 will gradually move to the end of the driving groove 20312 located on the inside. Similarly, when the end of the partition component 205 moves, the partition component 205 as a whole will also move with it, and the four groups of partition components 205 all move along the corresponding driving groove 20312, and eventually gather together to form a disc structure that can separate the airflow.

[0045] Among them, the reset component 204 includes a spiral spring 2041 that surrounds the outside of the driving component 203, an internal fixed head 2042 arranged at the inner end of the spiral spring 2041, and an external fixed head 2043 arranged at the outer end of the spiral spring 2041. The spiral spring 2041 is a spiral structure that surrounds the outside of the connecting component 2032. The internal fixed head 2042 is fixedly connected to the connecting component 2032, and the external fixed head 2043 is fixedly connected to the bearing component 206.

[0046] During use, when the driving component 203 rotates, it will drive the reset component 204 to move accordingly as a whole. Since the external fixing head 2043 is fixed on the bearing component 206, the reset component 204 can only be wound or unwound on the outside of the connecting component 2032. In addition, due to its own elasticity, once the external force disappears, the reset component 204 will quickly rebound and reset, thereby driving the driving component 203 to perform the reset work.

[0047] Among them, reference Figure 7 The partition assembly 205 includes a partition 2051 located below the driving component 203, and a limiting rod 2052 arranged at the outer end of the partition 2051, and the top of the limiting rod 2052 extends into the driving component 203. The top of the limiting rod 2052 is a cylindrical structure, extending into the driving groove 20312. The bottom of the limiting rod 2052 is a rectangular structure, extending into the bearing component 206. The partition 2051 is a fan-shaped structure. The four groups of partitions 2051 cooperate with each other to form a complete disc structure. The size of the disc structure is consistent with the size of the empty groove at the center position of the fixing ring 2012.

[0048] Among them, reference Figure 7The bearing component 206 includes a bearing assembly 2061 located at the top of the side plate 101, a tapered groove 2062 provided at the center of the bearing assembly 2061, and a plurality of bases 2063 provided on the fixing component 201. The partition assembly 205 is slidably connected to the base 2063. The tapered groove 2062 is a frustum structure with a thin top and a thick bottom. The bottom thereof is connected to the interior of the receiving unit 100. The top of the base 2063 is connected to the connecting groove 20113, and the partition assembly 205 is located between the channels connecting the two. Among them, the supporting assembly 2061 includes a supporting seat 20611, a guide groove 20612 arranged on one side of the supporting seat 20611, and two sets of guide wheels 20613 arranged in the guide groove 20612. The connecting rope 207 passes through the guide groove 20612 from the side of the supporting seat 20611, and is guided by the two sets of guide wheels 20613 and passes out from the other side of the supporting component 206.

[0049] Furthermore, the base 2063 includes a wide groove 20631 for accommodating the sliding and extension of the partition 2051, and a narrow groove 20632 opened in the wide groove 20631. The narrow groove 20632 is a rectangular structure, and the lower part of the limiting rod 2052 extends into the narrow groove 20632. The two rectangular structures cooperate with each other to limit the partition assembly 205 so that it can only move horizontally along the narrow groove 20632.

[0050] During use, when the cabinet door 102 is rotated outward and opened, the outward folded cabinet door 102 will stretch the connecting rope 207, and the connecting rope 207 will pull the connecting component 2032 to rotate. At this time, the reset component 204 surrounding the outside of the connecting component 2032 will be stretched and elastically expanded outward. Rotating the connecting component 2032 will drive the partition component 205 to rotate, but the partition component 205 is limited by the base 2063 and cannot rotate accordingly. Therefore, the partition component 205 can only move in a translational manner within the base 2063. The four groups of partition components 205 move inward in a translational manner at the same time, which will cut off the connection between the connecting groove 20113 and the tapered groove 2062. At this time, the air blown downward by the exhaust fan 2022 is blocked by the partition component 205 and will be discharged from the side of the fixed component 201 The air flows through the side groove 20112 into the positive exhaust duct 1041, and finally changes the air that was originally blown vertically downward to be blown horizontally outward through the positive exhaust port 1042, that is, blows in the direction of the opening of the cabinet door 102, thereby preventing external moisture from entering the interior of the device through the opened outlet of the cabinet door 102; on the contrary, when the cabinet door 102 is closed, the pulling force of the connecting rope 207 on the connecting component 2032 disappears, and the reset component 204 will elastically retract inward, thereby driving the connecting component 2032 to rotate in the reverse direction. The reverse rotating connecting component 2032 will reel in the previously extended connecting rope 207, and push the closed four groups of partition components 205 to move outward horizontally, so that the conical groove 2062 continues to be connected with the connecting groove 20113. At this time, the airflow direction triggered by the exhaust fan 2022 is vertically downward.

[0051] The remaining structures are the same as those of Example 1.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
