Description

Technical Field

[0001] This invention relates to the field of power operation and maintenance technology, specifically to a dehumidifier drainage device for a substation terminal box and a substation terminal box. Background Technology

[0002] Dehumidifiers are typically used in outdoor terminal boxes of substations to prevent condensation. The bottom of the dehumidifier is connected to a water outlet pipe. The operator forcefully loops the drain hose onto the water outlet pipe. The hose is fixed and sealed by the elastic deformation of the material and the friction and interference fit between the hose and the outer wall of the water outlet pipe, ensuring smooth drainage.

[0003] However, during use, manually forcibly fitting the hose onto the outlet requires considerable force to ensure the hose is inserted to the correct depth. Furthermore, the hose relies solely on its own elastic deformation to hold the connection in place, resulting in limited connection strength. Additionally, adjusting the hose's direction inevitably applies torsional or pulling forces, which are directly transmitted to the connection between the hose and the outlet, disrupting the original interference fit and causing the connection to loosen or even partially detach, thus affecting subsequent drainage operations. Summary of the Invention

[0004] This invention aims to at least partially address the problem of insufficient connection strength in the connection method of the drain hose of the dehumidifier in the outdoor terminal box of the substation in related technologies. To this end, this invention provides a drain device for the dehumidifier in the substation terminal box and a substation terminal box, which is simple and convenient to operate and ensures the long-term stable operation of the drain device.

Detailed Implementation

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 8As shown, the present invention provides a dehumidifier drainage device for a substation terminal box, which includes an outlet pipe 11, a drain pipe 12, and an installation assembly 13. One end of the outlet pipe 11 is connected to the dehumidifier 100, and the other end of the outlet pipe 11 is provided with an outlet 111. The drain pipe 12 is used to connect to the outlet 111 of the outlet pipe 11, and a positioning block 121 is provided on the outer side of the drain pipe 12. The installation assembly 13 includes a positioning seat 131, a sliding member 132, a contact plate 133, and a sliding block 134. The positioning seat 131 is connected to the dehumidifier 100. The sliding member 132 is slidably disposed on the positioning seat 131 along the axial direction of the drain pipe 12. The contact plate 133 is rotatably disposed on the sliding member 132. The sliding block 134 is slidably disposed on the positioning seat 131 along the axial direction of the drain pipe 12 and is disposed between the contact plate 133 and the sliding member 132. As the sliding member 132 moves toward the outlet pipe 11 along the axial direction of the drain pipe 12, the sliding member 132 pushes the sliding block 134 to move relative to the positioning seat 131 until the sliding block 134 abuts against the contact plate 133, so that the contact plate 133 abuts against the positioning block 121, thereby realizing the positioning and installation of the drain pipe 12.

[0028] Specifically, the outlet pipe 11 is used to connect to the dehumidifier 100 to discharge the liquid water produced by the dehumidifier 100. The shape and size of the outlet 111 can be adapted to the drain pipe 12 to achieve precise connection, ensuring that liquid water can flow smoothly from the outlet pipe 11 into the drain pipe 12. The drain pipe 12 is used to receive the outlet pipe 11 to discharge the liquid water in the outlet pipe 11. The positioning seat 131 is used to connect to the housing of the dehumidifier 100. During the process of connecting the drain pipe 12 to the outlet pipe 11, the sliding member 132 can move towards the outlet pipe 11. During the movement of the sliding member 132, the sliding member 132 will contact the sliding block 134 and gradually push the sliding block 134 relative to the positioning seat 131. Since the sliding block 134 is located between the abutment plate 133 and the sliding member 132, as the sliding block 134 moves, it gradually approaches the abutment plate 133 and eventually abuts against it. After the sliding block 134 abuts against the abutment plate 133, it continues to push the sliding member 132, causing the abutment plate 133 to rotate under the pushing force of the sliding block 134 and gradually abut against the positioning block 121 on the outside of the drain pipe 12. As the contact force between the abutment plate 133 and the positioning block 121 continuously increases, the drain pipe 12 will be firmly fixed in the installation position, achieving the positioning and installation of the drain pipe 12.

[0029] In summary, the substation terminal box dehumidifier drainage device provided by this invention, through the cooperation of the sliding member 132, the sliding block 134, and the contact plate 133, can achieve precise positioning and stable installation of the drain pipe 12. During installation, the operation is simple and convenient; simply pushing the sliding member 132 is sufficient to complete the installation of the drain pipe 12. Furthermore, the installed drain pipe 12 can withstand certain external impacts without easily shaking or shifting, ensuring the long-term stable operation of the drainage device.

[0030] like Figure 2 As shown, in some embodiments, the outlet pipe 11 has a first shaft section 112 and a second shaft section 113 connected to each other. The diameter of the second shaft section 113 is larger than the diameter of the first shaft section 112. One end of the drain pipe 12 is inserted into the second shaft section 113 and abuts against the end of the first shaft section 112, thereby realizing the receiving of liquid in the outlet pipe 11.

[0031] Furthermore, the dehumidifier drainage device in the substation terminal box also includes a sealing assembly 15. The sealing assembly 15 includes a first sealing ring 151 and a second sealing ring 152. The first sealing ring 151 is located at the end of the drain pipe 12 and abuts against the end of the first shaft segment 112. The second sealing ring 152 is sleeved on the outside of the drain pipe 12 and abuts against the end of the second shaft segment 113, thereby achieving a seal at the connection between the drain pipe 12 and the outlet pipe 11. The first sealing ring 151 and the second sealing ring 152 cooperate to achieve a double seal, which helps to improve the sealing effect.

[0032] like Figure 4 As shown, in some embodiments, the sliding member 132 includes a sliding ring 1321 and a support plate 1322 connected together. The sliding ring 1321 is sleeved on the outside of the drain pipe 12, and the support plate 1322 extends radially along the sliding ring 1321. The abutment plate 133 is rotatably mounted on the support plate 1322. The sliding ring 1321 is sleeved on the outside of the drain pipe 12 to ensure smooth sliding. The support plate 1322 extends radially toward the center of the sliding ring 1321 and is connected to it. One end of the abutment plate 133 can be rotatably connected to the support plate 1322, and the other end of the abutment plate 133 has a contact surface for abutting against the positioning block 121.

[0033] Furthermore, the sliding member 132 also includes a connecting plate 1323, which is L-shaped with the support plate 1322. The connecting plate 1323 is used to push against the sliding block 134, giving it better mechanical properties and stability when pushing the sliding block 134. The surface of the connecting plate 1323 is smooth to reduce friction with the sliding block 134 and ensure smooth pushing. In some embodiments, the connecting plate 1323 and the support plate 1321 may be integrally formed.

[0034] Furthermore, multiple support plates 1322 and contact plates 133 are provided. Multiple support plates 1322 are spaced apart along the circumferential direction of the sliding ring 1321. The contact plates 133 are connected to the support plates 1322 one by one to apply a uniform force to the positioning block 121 and avoid the positioning block 121 from deflecting or misaligning due to uneven force.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments, the mounting assembly 13 further includes a first spring 135, one end of which is connected to the abutment plate 133, and the other end of which is connected to the sliding member 132. The first spring 135 has a certain elastic restoring force, which can buffer the impact force of the sliding block 134 on the abutment plate 133, preventing the abutment plate 133 from being damaged due to excessive impact.

[0036] Furthermore, the first spring 135 is configured as a torsion spring, and a rotating shaft 136 is provided between the contact plate 133 and the support plate 1322 of the sliding member 132, with the torsion spring sleeved on the rotating shaft 136. The spring force of the torsion spring allows for a more stable and uniform contact between the contact plate 133 and the positioning block 121, improving installation stability. When disassembling the drain pipe 12, the spring force also helps the contact plate 133 quickly separate from the positioning block 121, making the disassembly process easier.

[0037] like Figures 1 to 5 As shown, in some embodiments, the mounting assembly 13 further includes a threaded sleeve 137, which is threadedly connected to the positioning seat 131. A connecting post 138 is provided between the threaded sleeve 137 and the sliding member 132. The positioning seat 131 has a first through hole 1311, and the connecting post 138 is movably inserted into the first through hole 1311. An operator can rotate the threaded sleeve 137 relative to the positioning seat 131. The engagement of the connecting post 138 with the first through hole 1311 converts the rotational motion of the threaded sleeve 137 into the linear motion of the sliding member 132, thereby moving the sliding member 132.

[0038] In some embodiments, the positioning seat 131 has a guide rod 1312 extending along the axial direction of the drain pipe 12. A sliding block 134 is slidably disposed on the guide rod 1312, and a second spring 139 is provided between the sliding block 134 and the positioning seat 131. The second spring 139 can provide a certain restoring force to the sliding block 134, so that the sliding block 134 can quickly return to its original position after being subjected to external force.

[0039] Furthermore, multiple guide rods 1312, sliding blocks 134, and second springs 139 can be provided, and they are arranged corresponding to the support plate 1322.

[0040] Furthermore, the second spring 139 is sleeved on the guide rod 1312, and the two ends of the second spring 139 are connected to the sliding block 134 and the positioning ring 1318 respectively. The end of the guide rod 1312 away from the positioning ring 1318 is also provided with a limiting piece 13121, which is used to limit the maximum movement stroke of the sliding block 134.

[0041] In this embodiment, the positioning seat 131 includes a threaded cylindrical section 1313 and a hollow section 1314 connected to each other. The hollow section 1314 has a receiving cavity 1315, and a sliding ring 1321 is movably disposed within the receiving cavity 1315. The inner sidewall of the hollow section 1314 has a first guide groove 1316, which corresponds one-to-one with the support plate 1322. The first guide groove 1316 extends along the axial direction of the drain pipe 12 to limit the movement direction of the support plate 1322. The sliding ring 1321 can abut against the inner wall (inner sidewall and outer sidewall) of the receiving cavity 1315 to make the movement of the sliding ring 1321 more precise.

[0042] Furthermore, a limiting rod 1317 is provided in the accommodating cavity 1315. The limiting rod 1317 extends along the axial direction of the drain pipe 12. A second through hole 1324 is provided on the support plate 1322. The limiting rod 1317 passes through the second through hole 1324, so that it can work together with the first guide groove 1316 to limit the movement direction of the support plate 1322, ensuring that the movement of the support plate 1322 is more reliable.

[0043] Of course, it is conceivable that the setting of the limit rod 1317 and the first guide groove 1316 can be selected as needed, or they can be used in combination.

[0044] Furthermore, the positioning seat 131 also includes a positioning ring 1318, which is fixedly disposed within the accommodating cavity 1315. Multiple guide rods 1312 are spaced apart along the circumferential direction of the positioning ring 1318, and each guide rod 1312 corresponds to a support plate 1322. A first through hole 1311 is located at the axial end of the hollow section 1314 to limit the movement direction of the sliding member 132.

[0045] During use, the threaded sleeve 137 is rotatably connected to the threaded cylinder section 1313. The operator can rotate the threaded sleeve 137, which can drive the sliding ring 1321 to move within the accommodating cavity 1315 via the connecting post 138. The sliding ring 1321 drives the support plate 1322 and its abutment plate 133 to move along the first guide groove 1316. When the connecting plate 1323 on the support plate 1322 abuts against the sliding block 134, the support plate 1322 will move along the first guide groove 1316 via the connecting plate 1328. 323 pushes the sliding block 134 to move until the sliding block 134 pushes against the contact plate 133 so that the contact plate 133 abuts against the positioning block 121. At this time, due to the threaded connection between the threaded sleeve 137 and the threaded cylinder section 1313, the position of the threaded sleeve 137 is fixed, and the positions of the sliding ring 1321, the support plate 1322 and the contact plate 133 are fixed, thereby realizing the positioning of the positioning block 121 on the drain pipe 12, and thus realizing the fixing of the drain pipe 12.

[0046] like Figure 6 , Figure 7 As shown, in some embodiments, the dehumidifier drainage device of the substation terminal box further includes an anti-detachment component 17. The anti-detachment component 17 includes a positioning member 171, a movable member 172, and a guide member 173. The guide member 173 is disposed on the positioning seat 131, and the positioning member 171 is disposed on the outer periphery of the drain pipe 12. A third spring 174 is provided between the movable member 172 and the guide member 173. The movable member 172 is slidably disposed on the guide member 173. The sliding ring 1321 is connected to the movable member 172 in a transmission manner to drive the movable member 172 to slide relative to the guide member 173, so that the movable member 172 is engaged with the positioning member 171 to prevent the drain pipe 12 from detaching from the outlet pipe 11.

[0047] Specifically, the guide 173 is a plate-like structure, and the movable part 172 is a sleeve-like structure. The movable part 172 is sleeved on the outside of the guide 173. The third spring 174 is located inside the cavity of the movable part 172, and its two ends are connected to the movable part 172 and the guide 173 respectively. Both the guide 173 and the movable part 172 are located within the accommodating cavity 1315 of the hollow cylindrical section. The inner sidewall of the hollow cylindrical section is provided with a second guide groove, through which the movable part 172 can be movably inserted to engage with the positioning part 171. The guide 173 can be connected to the outer sidewall of the hollow cylindrical section.

[0048] Furthermore, the movable part 172 is provided with two third springs 174, which are arranged side by side to provide sufficient force for the restoration of the movable part 172.

[0049] Furthermore, the movable part 172 is provided with a slot 1721, which is adapted to the external shape of the positioning part 171 to ensure that the positioning part 171 can be accurately positioned and fixed.

[0050] In some embodiments, the movable member 172 has a push plate 1722, which is inclined along the radial direction of the sliding ring 1321. The sliding ring 1321 is provided with a support frame 1325, which is used to push the push plate 1722 to move, thereby realizing the transmission connection between the sliding ring 1321 and the movable member 172.

[0051] Furthermore, the support frame 1325 is provided with a pulley 1326, which is connected to the push plate 1722, which helps to reduce friction.

[0052] In some embodiments, the anti-detachment component 17 can be configured in multiple groups, such as 2 groups, 3 groups, etc. In this embodiment, two groups of anti-detachment components 17 are provided, and the two groups of anti-detachment components 17 are symmetrically arranged on opposite sides of the drain pipe 12. The positioning member 171 is configured as an annular plate, which is sleeved on the outside of the drain pipe 12 and located below the positioning block 121.

[0053] like Figure 1 , Figure 8 As shown, in some embodiments, the dehumidifier drainage device of the substation terminal box further includes a limiting component 19. The limiting component 19 includes a positioning shell 191, a plug-in plate 192, a pull rod 193, and a fourth spring 194. The positioning shell 191 is located outside the dehumidifier 100. The plug-in plate 192 is slidably connected to the positioning shell 191. The pull rod 193 is connected to the plug-in plate 192. The two ends of the fourth spring 194 are correspondingly connected to the plug-in plate 192 and the positioning shell 191. The positioning seat 131 is provided with a positioning groove 1319. The plug-in plate 192 is used to be inserted into the positioning groove 1319.

[0054] Specifically, the positioning housing 191 includes an annular body 1911 and a guide frame 1912. The annular body 1911 is fixed to the housing of the dehumidifier 100. The guide frame 1912 has a sliding cavity 1913. One end of the plug-in plate 192 has a sliding plate 195, which is movably disposed in the sliding cavity 1913. The two ends of the fourth spring 194 are correspondingly connected to the inner wall of the sliding cavity 1913 and the sliding plate 195. The pull rod 193 has a rod body 1931 and a pull ring 1932. The rod body 1931 is movably inserted through the sliding cavity 1913 and connected to the sliding plate 195.

[0055] When the positioning seat 131 needs to be detached from the dehumidifier 100, the operator can pull the pull ring 1932. The pull ring 1932 can drive the sliding plate 195 and the plug plate 192 to move, so that the plug plate 192 moves away from the positioning seat 131 and the fourth spring 194 undergoes elastic deformation, which facilitates the detachment of the positioning seat 131 from the dehumidifier 100. Then the operator releases the pull ring 1932. Under the action of the elastic deformation force of the fourth spring 194, the fourth spring 194 will drive the sliding plate 195 and the plug plate 192 to return to their original positions.

[0056] When the positioning seat 131 needs to be installed, the operator can pull the pull ring 1932. The pull ring 1932 can drive the sliding plate 195 and the plug plate 192 to move, so that the plug plate 192 moves away from the positioning seat 131 and the fourth spring 194 undergoes elastic deformation, which facilitates the positioning seat 131 to be connected to the liquid outlet of the dehumidifier 100. Then the operator releases the pull ring 1932. Under the action of the elastic deformation force of the fourth spring 194, the fourth spring 194 will drive the sliding plate 195 and the plug plate 192 to return to their original position and be inserted into the positioning groove 1319 on the positioning seat 131, realizing mechanical interlock and realizing the positioning and installation of the positioning seat 131.

[0057] Furthermore, the plug plate 192 has a wedge 1921, which has a flat surface 1922 and an inclined surface 1923. The inclined surface 1923 is located on the side of the flat surface 1922 away from the dehumidifier 100. The positioning groove 1319 has a shape that matches the wedge 1921, thereby facilitating the installation of the positioning seat 131. For example, during installation, the operator can apply force to the positioning seat 131, causing it to move toward the liquid outlet of the dehumidifier 100. The positioning seat 131 can abut against the inclined surface 1923 of the wedge 1921. The positioning seat 131 can push against the inclined surface 1923, causing the plug plate 192 to move until the positioning groove 1319 moves to the position corresponding to the wedge 1921. Under the elastic restoring force of the fourth spring 194, the plug plate 192 inserts the wedge 1921 into the positioning groove 1319, thereby achieving the positioning and installation of the positioning seat 131. This also facilitates the inspection and cleaning of the positioning seat 131.
