Description

Technical Field

[0001] This application relates to the technical field of cable branch boxes, and in particular to a cable branch box with dehumidification function. Background Technology

[0002] With the continuous development of cable-based power distribution networks, cable distribution boxes can be used to connect multiple branches of cables when independent loads of small capacity are concentrated in a relatively concentrated area. The main function of cable distribution boxes is to branch or transfer cables, and they are widely used in various types of power distribution networks.

[0003] In related technologies, cable distribution boxes include a box body, a door hinged to the box body, and cables installed inside the box body. Several ventilation holes are provided on the side walls of the box body, allowing heat generated by the cables during operation to be dissipated outwards through these holes.

[0004] However, when the aforementioned cable distribution boxes are used in areas with high air humidity, moisture can easily enter the interior of the box through the ventilation holes, leading to faster corrosion, shorter service life, and even short circuits and other safety accidents, which needs to be improved. Summary of the Invention

[0005] To effectively remove moisture from the enclosure, this application provides a cable branch box with dehumidification function.

[0006] The cable distribution box with dehumidification function provided in this application adopts the following technical solution: A cable distribution box with dehumidification function includes a box body and a door hinged to the box body. The box body has an installation cavity for accommodating cables. The cavity wall of the installation cavity has several sets of ventilation holes. The box body is provided with a dehumidification mechanism for removing moisture from the installation cavity. The dehumidification mechanism includes a mounting frame slidably mounted on the box body, several dehumidification plates rotatably mounted on the mounting frame, a pushing component for driving the mounting frame to move towards or away from the adjacent ventilation holes, and a rotating component for driving each dehumidification plate to rotate relative to the box body. The number of dehumidification plates is equal to the number of ventilation holes and they correspond one-to-one. Each dehumidification plate can be moved to the side of the adjacent ventilation hole facing the installation cavity.

[0007] By adopting the above technical solution, when the cable distribution box is used in humid areas with high air humidity, the dehumidifying plate can effectively absorb moisture in the installation cavity, thereby playing a role in drying and dehumidifying. When the horizontal component is working, the mounting bracket will move towards or away from the ventilation hole, thereby changing the distance between the dehumidifying plate and the ventilation hole to adapt to different dehumidification needs. When the rotating component is working, the dehumidifying plate will rotate relative to the box body, which not only expands the contact range between the dehumidifying plate and the moisture and enhances the dehumidification effect, but also allows the dehumidifying surface of the dehumidifying plate to be turned to the side facing the ventilation hole after the dehumidifying plate is saturated with moisture, so as to utilize sunlight or external wind to dry the dehumidifying plate. Compared with the traditional fixed placement of dehumidifying plates, the dehumidification method of this application has a larger dehumidification range and better effect. The side walls of the box are not easily corroded by moisture, resulting in a longer service life. Short circuits and other safety accidents are less likely to occur in the cable distribution box, reducing safety hazards.

[0008] Optionally, the mounting bracket is vertically slidably mounted on the housing, and the cross-sectional area of ​​the dehumidification plate is larger than the cross-sectional area of ​​the adjacent ventilation hole; the push assembly includes an extension block fixedly connected to the mounting bracket, a push block vertically slidably connected to the extension block, and a power component for driving the push block to move towards or away from the side wall of the housing. A bracket is fixedly connected to the housing, the power component is mounted on the bracket, and the extension block has a push groove that slides with the push block. The opening of the push groove on the side closer to the power component is smaller than the opening on the side away from the power component.

[0009] By adopting the above technical solution, during rainy weather, the power component first drives the push block to move towards the side wall of the enclosure, causing the extension block to simultaneously push the mounting bracket towards the ventilation hole. Then, the vertical sliding mounting bracket blocks the adjacent ventilation hole to prevent rainwater from entering the enclosure through the ventilation hole. After the rain ends, the power component drives the push block away from the side wall of the enclosure, and the extension block, mounting bracket, and dehumidifying plate move synchronously with the push block, opening the ventilation hole to facilitate heat dissipation.

[0010] Optionally, the mounting frame includes a mounting frame and a positioning rod fixedly connected to the middle of the mounting frame. The positioning rod has a vertically extending positioning groove. The rotating assembly includes a sliding rack slidably disposed in the positioning groove, a lifting member for driving the sliding rack to move vertically, and a plurality of rotating gears meshing on one side of the sliding rack. Each of the rotating gears is fixedly connected to an adjacent dehumidifying plate through a rotating shaft.

[0011] By adopting the above technical solution, when the lifting component is working, the sliding rack slides vertically along the positioning groove, causing each rotating gear to drive the dehumidifying plate connected to it to rotate circumferentially, thereby changing the orientation of the dehumidifying surface in the dehumidifying plate. The movement of each dehumidifying plate is driven by a set of lifting components as a power source, which has high synchronization and resource-saving efficiency.

[0012] Optionally, a support plate is abutted against the lower side of the mounting frame, and several sets of support members are provided between the bottom wall of the box and the support plate. The support members include guide sleeves and elastic members abutted against the support plate and the guide sleeves. The elastic members exert an upward force on the support plate, so that each dehumidifying plate can block the adjacent ventilation holes respectively.

[0013] By adopting the above technical solution, the elastic element tends to drive the dehumidification plate to block the ventilation hole, making the dehumidification plate less likely to move relative to the ventilation hole and providing a good rain-blocking effect.

[0014] Optionally, a connecting rod is fixedly provided on the upper side of the mounting frame. The connecting rod slides through the top wall of the box, and a material box located outside the box is provided at the top of the connecting rod. The material box is provided with a receiving slot for storing materials.

[0015] By adopting the above technical solution, since the material bin is located on the outside of the box, operators can place materials of different weights into the receiving slot during use of the cable branch box, causing the material bin to exert different degrees of pressure on the mounting frame. After being pressed, the mounting frame will drive the dehumidification plate to move vertically, causing the dehumidification plate to change the area of ​​obstruction of the ventilation holes, thereby adjusting the size of the ventilation hole openings to adapt to different ventilation needs, making it highly practical.

[0016] Optionally, a locking block is fixedly installed on the housing, and a locking bolt is threaded into the locking block. The connecting rod has a first locking hole and a second locking hole for the locking bolt to extend into, with the first locking hole located directly above the second locking hole.

[0017] By adopting the above technical solution, when the locking bolt is inserted into the first locking hole or the second locking hole, the connecting rod is limited by the locking bolt and cannot move, which helps to improve the stability of the dehumidification mechanism and prevent the dehumidification mechanism from shaking when the cabinet is vibrated.

[0018] Optionally, a fixing ring is provided on the circumferential side wall of the connecting rod, and a plurality of stop blocks are provided on the side of the fixing ring facing the housing. A stop groove is provided on the top wall of the housing for the stop blocks to extend vertically. When the locking bolt is inserted into the first locking hole, the stop block is inserted into the stop groove.

[0019] By adopting the above technical solution, when the locking bolt is inserted into the first locking hole, the stop block will engage with the stop groove, thereby further restricting the movement of the connecting rod and helping to further improve the stability of the mounting bracket and dehumidification plate.

[0020] Optionally, the top wall of the housing is provided with a clearance hole for the horizontal sliding of the connecting rod, and the wall of the clearance hole and the connecting rod are sealed with an elastic waterproof cloth.

[0021] By adopting the above technical solution, the waterproof cloth can prevent rainwater from seeping into the installation cavity through the clearance hole, thus avoiding safety accidents such as short circuits.

[0022] Optionally, the dehumidification plate includes a substrate and a drying plate detachably disposed on one side of the substrate. The drying plate is filled with a desiccant, and a plurality of drying holes are formed on the side wall of the drying plate away from the substrate.

[0023] By adopting the above technical solution, moisture in the chamber can enter the inner cavity of the drying plate through the drying holes and be adsorbed by the desiccant, thereby achieving the purpose of dehumidification. The drying plate is detachable rather than fixedly connected to the base plate, allowing the drying plate to be removed from the base plate for timely replacement of a saturated drying plate.

[0024] Optionally, the drying plate is a transparent plate, and the desiccant is a cobalt-free color-changing silica gel desiccant.

[0025] By adopting the above technical solution, the color of the cobalt-free color-changing silica gel desiccant changes depending on the degree of moisture absorption. When dry, it is orange; as it absorbs more moisture, the color gradually turns green and then dark green. The desiccant plate is transparent, allowing operators to observe its moisture absorption status and facilitate timely replacement.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A dehumidifying plate is installed in the cabinet at the position corresponding to the ventilation hole. The dehumidifying plate can slide and rotate relative to the cabinet, which has the advantages of large dehumidification range and good effect. 2. When materials of different weights are fed into the hopper, the mounting frame will undergo different degrees of vertical displacement, causing the area of ​​the dehumidifying plate covering the ventilation holes to change in order to adapt to different ventilation requirements; the elastic element has the tendency to drive the support plate to push the mounting frame upward, which helps to improve the stability of the dehumidifying plate when it covers adjacent ventilation holes. 3. When the locking bolt is connected to the first locking hole, the mounting bracket is in the lowest position, the dehumidifying plate and the ventilation hole are misaligned, and the heat generated by the cable during operation can be discharged outward along the ventilation hole; when the locking bolt is connected to the second locking hole, the mounting bracket is in the highest position, the dehumidifying plate and the ventilation hole are aligned, and rainwater is blocked by the dehumidifying plate and is not easy to enter the mounting cavity along the ventilation hole; the locking bolt can restrict the vertical sliding of the connecting rod, thereby improving the stability of the dehumidification mechanism.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a cable branch box with dehumidification function.

[0037] Reference Figure 1 The cable distribution box with dehumidification function includes a box body 1 and a door 2 hinged to one side of the box body 1. The box body 1 has an installation cavity 11 for accommodating cables. Several sets of ventilation holes 12 are respectively formed on the opposite side walls of the installation cavity 11. This embodiment illustrates its structure with two sets of ventilation holes 12 on the same cavity wall. The two sets of ventilation holes 12 are spaced apart horizontally, and each set of ventilation holes 12 has multiple holes distributed vertically.

[0038] Reference Figure 1 , Figure 2The housing 1 is equipped with a dehumidification mechanism 3 for removing moisture from the mounting cavity 11. The dehumidification mechanism 3 has two sets, which correspond to the two side walls of the housing 1 where ventilation holes 12 are provided. The dehumidification mechanism 3 includes a mounting frame 31, several dehumidification plates 32 rotatably mounted on the mounting frame 31, a horizontal pushing component 33 for driving the mounting frame 31 to move horizontally, and a rotating component 34 for driving the dehumidification plates 32 to rotate circumferentially. The mounting frame 31 is slidably mounted on the housing 1. The number of dehumidification plates 32 is equal to the number of ventilation holes 12 and they correspond one-to-one. The cross-sectional area of ​​the dehumidification plates 32 is larger than the cross-sectional area of ​​the ventilation holes 12, so that the dehumidification plates 32 can block the adjacent ventilation holes 12.

[0039] Reference Figure 2 , Figure 3 The mounting frame 31 includes a mounting frame 311 and a positioning rod 312 fixedly connected to the middle of the mounting frame 311. A connecting rod 35 is fixedly installed on the upper side of the mounting frame 311. A horizontally extending clearance hole 13 is provided on the top wall of the housing 1, and the connecting rod 35 slides through the clearance hole 13. To prevent rainwater from seeping into the mounting cavity 11 along the clearance hole 13, a waterproof cloth 14 is sealed between the hole wall of the clearance hole 13 and the connecting rod 35. The waterproof cloth 14 is made of a waterproof fabric that can produce elastic deformation. In this embodiment, it is preferably a four-way stretch fabric.

[0040] Reference Figure 2 , Figure 3 The top of the connecting rod 35 is fixedly connected to the material box 4, which is located on the outside of the box body 1 and has a receiving slot 41 for storing materials. When materials of different weights are put into the material box 4, the connecting rod 35 will be pushed downward by the pressure of the material box 4, which will cause the relative position of the dehumidification plate 32 and the ventilation hole 12 to change.

[0041] Reference Figure 3 , Figure 4 A locking block 15 is fixedly installed on the top wall of the housing 1. A locking bolt 151 is threaded into the locking block 15. The connecting rod 35 has a first locking hole 351 and a second locking hole 352 vertically distributed. The first locking hole 351 is located directly above the second locking hole 352, and the inner diameters of both the first locking hole 351 and the second locking hole 352 are larger than the diameter of the rod of the locking bolt 151. When the locking block 15 is inserted into the first locking hole 351, the mounting bracket 31 is in the lowest position, the dehumidifying plate 32 is misaligned with the ventilation hole 12, and the heat generated by the cable during operation can be discharged outward along the ventilation hole 12. When the locking block 15 is inserted into the second locking hole 352, the mounting bracket 31 is in the highest position, the dehumidifying plate 32 is aligned with the ventilation hole 12, and rainwater is blocked by the dehumidifying plate 32 and does not easily enter the mounting cavity 11 along the ventilation hole 12.

[0042] Reference Figure 3 , Figure 4A retaining ring 353 is fixed to the circumferential side wall of the connecting rod 35. Several stop blocks 354 are fixed to the side of the retaining ring 353 facing the housing 1. A stop groove 16 is provided on the top wall of the housing 1 for each stop block 354 to extend vertically. The depth of the stop groove 16 is less than the length of the stop block 354. When the locking bolt 151 is inserted into the first locking hole 351, the stop block 354 is inserted into the stop groove 16, which helps to further improve the stability of the connecting rod 35 and the mounting bracket 31. When the locking bolt 151 is inserted into the second locking hole 352, the stop block 354 is located on the upper side of the stop groove 16, and a gap is formed between the retaining ring 353 and the housing 1 for the locking bolt 151 to extend into.

[0043] Reference Figure 5 , Figure 6 To ensure that the dehumidifying plate 32 remains in the position blocking the ventilation hole 12 after the locking bolt 151 is pulled out of the connecting rod 35, a support plate 5 is abutted against the lower side of the mounting frame 311. Several sets of support members 6 are arranged between the support plate 5 and the bottom wall of the housing 1, and the support members 6 are spaced apart in the horizontal direction. The support member 6 includes a guide sleeve 61 fixed on the housing 1 and an elastic member 62 abutting between the support plate 5 and the guide sleeve 61. The elastic member 62 is preferably a spring. The elastic member 62 exerts an upward force on the support plate 5. After the material in the material box 4 is removed, the support plate 5 will push the mounting frame 31 upward under the action of the elastic member 62, so that each dehumidifying plate 32 blocks the adjacent ventilation hole 12.

[0044] Reference Figure 6 The dehumidification plate 32 includes a substrate 321 and a drying plate 322 detachably disposed on one side of the substrate 321. The drying plate 322 is made of a transparent material, such as acrylic sheet. The connection method between the drying plate 322 and the substrate 321 can be any one or more combinations of bolt connection, snap-fit ​​connection, or magnetic connection. In this embodiment, snap-fit ​​connection is preferred. When the drying plate 322 is connected to the substrate 321, the edges of the two are aligned with each other.

[0045] Reference Figure 6 The drying plate 322 is filled with a desiccant, preferably a cobalt-free color-changing silica gel desiccant. Multiple drying holes 323 are provided on the side wall of the drying plate 322 away from the substrate 321. Moisture in the housing 1 enters the inner cavity of the drying plate 322 through the drying holes 323 and is absorbed by the desiccant. After absorbing moisture, the color of the desiccant changes from orange to green and then to dark green.

[0046] Reference Figure 5 , Figure 7Each dehumidification mechanism 3 is connected to two sets of horizontal pushing components 33, which are located diagonally opposite each other on the mounting frame 31. Each horizontal pushing component 33 includes an extension block 331, a horizontal pushing block 332 vertically slidably mounted on the extension block 331, and a power component 333 for driving the horizontal pushing block 332 to move horizontally. The extension block 331 is fixedly connected to the mounting frame 311. The casing 1 has ventilation holes 12, and brackets 17 are fixedly mounted diagonally on its walls. The power component 333 includes a power cylinder mounted on the bracket 17, with the cylinder barrel fixed to the bracket 17 and the piston rod horizontally positioned and fixedly connected to the horizontal pushing block 332.

[0047] Reference Figure 7 The extension block 331 has a vertically extending flat push groove 334. The flat push block 332 is slidably disposed in the flat push groove 334. Specifically, the cross-sections of both the flat push block 332 and the flat push groove 334 are T-shaped, and the opening of the flat push groove 334 on the side closer to the power component 333 is smaller than the opening on the side farther from the power component 333. When the power component 333 is working, the flat push block 332 pushes the extension block 331 toward or away from the side wall of the housing 1, causing the mounting bracket 31 to drive the dehumidification plate 32 to move synchronously, thereby changing the distance between the dehumidification plate 32 and the ventilation hole 12. For example, on rainy days, the piston rod of the power cylinder can be extended so that the dehumidification plate 32 blocks the ventilation hole 12 to prevent rainwater from entering the housing 1 along the ventilation hole 12; on sunny days, the piston rod of the power cylinder can be shortened so that a ventilation gap is formed between the dehumidification plate 32 and the ventilation hole 12 to facilitate the dissipation of heat in the housing 1. Reference Figure 6 The rotating assembly 34 includes a sliding rack 341, a lifting member 342 for driving the sliding rack 341 to move vertically, and a plurality of rotating gears 343 meshing on one side of the sliding rack 341. A vertically extending positioning groove 313 is provided on the positioning rod 312, and the sliding rack 341 is slidably disposed in the positioning groove 313. The lifting member 342 includes a lifting cylinder disposed on the bottom wall of the positioning groove 313, with the piston rod of the lifting cylinder facing upwards and fixedly connected to the sliding rack 341.

[0048] Reference Figure 6 The number of rotating gears 343 is equal to the number of rows of ventilation holes 12, and each rotating gear 343 is fixedly connected to an adjacent dehumidifying plate 32 via a rotating shaft 344. To improve the linkage of each dehumidifying plate 32, in this embodiment, each rotating gear 343 is connected to two dehumidifying plates 32. When the lifting member 342 is working, the sliding rack 341 will slide vertically relative to the positioning rod 312, causing each rotating gear 343 to drive the dehumidifying plate 32 to rotate, thereby changing the orientation of the dehumidifying surface in the dehumidifying plate 32 to expand the dehumidification range and improve the dehumidification effect.

[0049] It should be noted that the aforementioned dehumidification surface refers to the side of the dehumidification plate 32 with drying holes 323. Before rotating the dehumidification plate 32, the mounting bracket 31 should be pushed away from the side wall of the housing 1 using the flat push assembly 33, so that a clearance space is formed between the mounting bracket 31 and the side wall of the housing 1 for the dehumidification plate 32 to rotate. The width of the clearance space should be greater than the maximum distance between the dehumidification plate 32 and the central axis of the rotating shaft 344.

[0050] The implementation principle of a cable distribution box with dehumidification function according to an embodiment of this application is as follows: When the cable distribution box is working normally, the locking bolt 151 passes through the first locking hole 351, and the dehumidification surface of the dehumidification plate 32 faces the inside of the mounting cavity 11. At this time, the ventilation hole 12 is in the open state, and the heat generated by the cable in the box 1 during operation can be discharged outward along the ventilation hole 12. The dehumidification plate 32 can effectively remove moisture from the box 1. In rainy weather, the locking bolt 151 passes through the second locking hole 352. After the mounting bracket 31 is pushed against the side wall of the box 1 by the flat pushing component 33, the dehumidification plate 32 can block the adjacent ventilation hole 12 to prevent rainwater from entering the mounting cavity 11 along the ventilation hole 12. The dehumidification plate 32 in this application can both slide relative to the box 1 and rotate relative to the box 1. The contact area between the dehumidification plate 32 and the moisture in the box 1 is large, and the dehumidification range is wide.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
