[0051] Please also read Figures 1 to 11 The ring main unit provided in the present application is now described. The ring main unit provided in the present application comprises a cabinet body 1 and a flow guide component 4.

[0052] The cabinet 1 adopts a vertical structure with a hollow interior, and the top of the cabinet 1 has a plurality of heat dissipation holes 11 connected to the interior of the cabinet 1. The cabinet 1 has a turntable 2 inside, the cross section of which is circular, the axial direction is parallel to the up-down direction, and the turntable 2 is connected to the inner top surface of the cabinet 1 in a rotatable manner in the up-down direction, and a driving structure 3 is provided between the turntable 2 and the cabinet 1.

[0053] In this embodiment, the aforementioned multiple heat dissipation holes 11 are arranged at intervals around the central axis of the turntable 2; the turntable 2 is provided with a plurality of air outlet holes 21 for correspondingly connecting with the multiple heat dissipation holes 11, and the upper side of the turntable 2 is also provided with a plurality of grooves 22 for correspondingly connecting with the multiple heat dissipation holes 11.

[0054] Based on this, in actual use, by manually adjusting the driving structure 3, the turntable 2 can be rotated so that the multiple air outlet holes 21 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence, or the multiple grooves 22 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence.

[0055] In this embodiment, each groove 22 is arranged to avoid the air outlet 21 to avoid liquid overflow due to the connection between the groove and the hole; and a water absorbent member 10 is embedded in the interior of each groove 22. The function of this water absorbent member 10 is to absorb the liquid entering the interior of the groove 22 to slow down the flow rate of the liquid, and at the same time act as a barrier to prevent the liquid from carrying moisture through.

[0056] The bottom of each groove 22 is provided with a plurality of through holes 23 penetrating to the lower side of the turntable 2 , so that the liquid seeping from the bottom of the water absorbing member 10 in the groove 22 is discharged to the inner space of the cabinet 1 below the turntable 2 through the through holes 23 .

[0057] The guide component 4 is arranged inside the cabinet 1, its inlet is connected to each through hole 23, and its outlet is located outside the cabinet 1; in actual use, this guide component 4 can recover the liquid discharged from each through hole 23, and can also discharge the liquid to the outside of the cabinet 1 to prevent the liquid from dripping onto the electrical equipment inside the cabinet 1 and affecting the normal use of the electrical equipment.

[0058] In the embodiment of the present application, the turntable 2 can be rotated by the driving structure 3 to adjust the position of the turntable 2 so that the multiple air outlet holes 21 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence, or the multiple grooves 22 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence; specifically, when the multiple air outlet holes 21 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence, the hot air inside the cabinet 1 can be discharged to the outside of the cabinet 1 through the interconnected air outlet holes 21 and the heat dissipation holes 11 to ensure timely and effective heat dissipation of the cabinet 1; when the multiple grooves 22 are connected to the multiple heat dissipation holes 11 in a one-to-one correspondence, the liquid (usually rainwater) falling from the top of the cabinet 1 will enter the grooves 22 through the heat dissipation holes 11 and be absorbed by the water absorbent 10; as the amount of liquid absorbed by the water absorbent 10 continues to increase, the liquid will gradually seep to the bottom of the groove 22 and be discharged into the guide component 4 through the through hole 23, so as to finally be discharged to the outside of the cabinet 1 through the guide component 4 to prevent the liquid from dripping onto the electrical equipment inside the cabinet 1.

[0059] It should be noted that the liquid that enters the heat dissipation holes 11 and is discharged by the guide component 4 is not only the liquid that falls directly into the heat dissipation holes 11, but also (based on the special structure adopted at the top of the cabinet 1) the liquid that was originally on the outer top surface of the cabinet 1 and then gradually flows into the heat dissipation holes 11; therefore, the ring network cabinet proposed in the present application not only has the ability to discharge the liquid that falls directly into the heat dissipation holes 11, but also has the ability to collect and discharge the liquid retained on the top of the ring network cabinet. The combination of the two can enable the ring network cabinet to be used stably in different rainy environments, thereby improving the versatility and safety of the ring network cabinet proposed in the present application.

[0060] Compared with the prior art, the ring main unit provided in this embodiment can prevent rainwater from entering the cabinet through the heat dissipation holes 11 while ensuring the heat dissipation performance of the ring main unit, thereby ensuring the normal use of electrical equipment.

[0061] In some embodiments, Figure 3As shown, a mounting groove 12 is formed on the inner top surface of the cabinet 1 , and each heat dissipation hole 11 penetrates from the top surface of the cabinet 1 to the bottom of the mounting groove 12 , and each heat dissipation hole 11 extends along the radial direction of the mounting groove 12 .

[0062] In this embodiment, the mounting groove 12 adopts a groove body structure with a circular cross-section, and the inner diameter of the mounting groove 12 is equal to the outer diameter of the turntable 2; when actually assembled, the turntable 2 is embedded in the interior of the mounting groove 12, and the turntable 2 is rotatably connected to the bottom of the mounting groove 12 in the up and down directions.

[0063] Based on this, the lower side of the turntable 2 is coplanar with the inner top surface of the cabinet 1, that is, the turntable 2 is installed in a sunken manner on the inner top surface of the cabinet 1, avoiding occupation of the internal space of the cabinet 1 and ensuring the reasonable arrangement of electrical equipment inside the cabinet 1.

[0064] In some embodiments, Figure 3 and Figure 5 As shown, a receiving groove 121 is provided on the inner peripheral wall of the aforementioned installation groove 12 , and a strip-shaped hole 13 communicating with the receiving groove 121 is also provided on the inner top surface of the cabinet body 1 .

[0065] In this embodiment, the driving structure 3 includes a plurality of tooth grooves 31 and a driving rack 32 .

[0066] The plurality of tooth grooves 31 are all formed on the outer peripheral wall of the turntable 2 . The plurality of tooth grooves 31 are arranged at intervals along the circumference of the turntable 2 . Each tooth groove 31 is adapted to face the receiving groove 121 and communicate with the receiving groove 121 .

[0067] The driving rack 32 is slidably disposed inside the accommodating groove 121 along the tangential direction of the rotating disk 2 , and the tooth portion of the driving rack 32 extends toward the mounting groove 12 and meshes with the tooth groove 31 .

[0068] The extension direction of the strip hole 13 is parallel to the sliding direction of the driving rack 32; and the driving rack 32 has a transmission part 321 that passes through the strip hole 13 and extends out, and the transmission part 321 is connected to a linear driving cylinder 322 for driving it to move along the extension direction of the strip hole 13.

[0069] By adopting the above-mentioned technical scheme, when the linear drive cylinder 322 is started, the power output end of the linear drive cylinder 322 can drive the driving rack 32 to move through the transmission part 321 (at this time, the strip hole 13 and the transmission part 321 cooperate to realize the sliding connection between the driving rack 32 and the cabinet 1 and limit the sliding direction of the driving rack 32), so as to achieve the technical purpose of rotating the turntable 2 to a certain angle through the meshing relationship between the driving rack 32 and the tooth groove 31.

[0070] It should be noted that, in order to achieve high efficiency in adjusting the ring main unit, the linear drive cylinder 322 is usually remotely controlled through a controller to facilitate network maintenance.

[0071] In some embodiments, Figure 7 and Fig. 9 As shown, the absorbent member 10 is a block structure made of sponge material. To ensure the use effect of the absorbent member 10 , the cross section of the absorbent member 10 is usually adapted to the cross section of the groove 22 , and the outer peripheral wall of the absorbent member 10 is connected to the inner peripheral wall of the groove 22 .

[0072] In this embodiment, a lifting plate 5 is provided between each water absorbing member 10 and the bottom of the groove 22;

[0073] In actual use, the lifting plate 5 is adapted to move in the up and down directions relative to the turntable 2 , and the outer peripheral wall of the lifting plate 5 is connected to the inner peripheral wall of the groove 22 to limit the liquid entering the groove 22 from the edge of the lifting plate 5 to flow into the lower side of the lifting plate 5 .

[0074] The lifting plate 5 has a plurality of drainage holes 51 correspondingly connected to the plurality of through holes 23 , and the lower side of the lifting plate 5 is also fixedly connected to a plurality of drainage pipes 52 correspondingly connected to the plurality of drainage holes 51 and plugged into the plurality of through holes 23 .

[0075] By adopting the above technical solution, the liquid entering the groove 22 will first pass through the water absorbent member 10 to be absorbed, blocked and slowed down by the water absorbent member 10; then, the liquid will fall on the upper side of the lifting plate 5, and then enter the drain pipe 52 through the drain hole 51, and finally enter the cabinet 1 through the through hole 23 and fall into the interior of the guide assembly 4.

[0076] In some embodiments, Figure 2 and Fig. 9 As shown, the lower side of the turntable 2 has a plurality of collectors 6 corresponding one-to-one to the plurality of grooves 22; wherein each collector 6 is connected to the lower end of the corresponding plurality of drain pipes 52, and the collector 6 adopts an internal hollow structure, and the interior of the collector 6 is connected to the corresponding plurality of drain pipes 52, so as to realize the convergence of liquid discharged from the plurality of drain pipes 52 in the same groove 22, making the device more convenient for directional discharge and recovery of the converged liquid.

[0077] In this embodiment, the lower side of each conduit 6 is connected to a positioning tube 61 that is connected to the interior thereof, that is, the liquid gathered by the conduit 6 will be discharged in a direction under the action of the positioning tube 61; based on this, the aforementioned guide assembly 4 is fixedly arranged on the inner top surface of the cabinet 1 and is connected to multiple positioning tubes 61 for recovering the liquid discharged from each positioning tube 61.

[0078] In some embodiments, Fig. 9 and Fig.11 As shown, each collector 6 is provided with an elastic reset member 7 between the turntable 2 , and the elastic reset member 7 is used to drive the collector 6 to move toward the turntable 2 , so that the lifting plate 5 moves upward relative to the water absorbing member 10 .

[0079] By adopting the above technical solution, when the water absorbent 10 is located inside the groove 22 and the lifting plate 5 and the water absorbent 10 are connected, the elastic reset member 7 is in an elastic deformation state, so that when the multiple air outlet holes 21 are connected with the multiple heat dissipation holes 11 in a one-to-one correspondence, the lifting plate 5 and the groove bottom of the groove 22 squeeze the water absorbent 10 to accelerate and ensure the water squeezing efficiency of the water absorbent 10; or, when the multiple grooves 22 are connected with the multiple heat dissipation holes 11 in a one-to-one correspondence, the water absorbent 10 blocks the corresponding heat dissipation holes 11 and part of the water absorbent 10 is embedded in the heat dissipation holes 11, thereby improving the stability of the water absorbent 10 in the process of absorbing liquid.

[0080] In some embodiments, Fig.11 As shown, the elastic reset member 7 includes a gate frame 71 and a spring 72 .

[0081] The door frame 71 is fixedly connected to the lower side of the turntable 2, and has a horizontal portion directly below the collector 6; that is, the door frame 71 includes two vertical portions and one horizontal portion; the two vertical portions are respectively arranged on both sides of the collector 6 along the circumference of the turntable 2, and are both fixedly connected to the lower side of the turntable 2 and extend downward, and the two ends of the horizontal portion are respectively fixedly connected to the lower ends of the two vertical portions to form a structure with a vertical cross-section in the shape of a gate, so that the horizontal portion is fixed to the lower side of the collector 6.

[0082] In actual use, the horizontal portion can also limit the downward movement of the collector 6; specifically, when the collector 6 moves downward to the bottom of the groove 22 where the lifting plate 5 abuts, the lower side surface of the collector 6 abuts against the upper side surface of the horizontal portion to support the lifting plate 5. At the same time, the aforementioned elastic reset member 7 also enables the lifting plate 5 to maintain an upward movement trend to ensure that the water absorbing member 10 on the upper side of the lifting plate 5 can gradually seep water outward.

[0083] The spring 72 is disposed between the aforementioned transverse portion and the current collector 6 , and two ends of the spring 72 are connected to the current collector 6 and the transverse portion respectively.

[0084] By adopting the above technical solution, when the water absorbent 10 is located inside the groove 22 and the lifting plate 5 and the water absorbent 10 are connected, the spring 72 is in an elastic contraction state, so that when the multiple air outlet holes 21 are connected with the multiple heat dissipation holes 11 in a one-to-one correspondence, the lifting plate 5 and the groove bottom of the groove 22 squeeze the water absorbent 10, or when the multiple grooves 22 are connected with the multiple heat dissipation holes 11 in a one-to-one correspondence, the water absorbent 10 blocks the corresponding heat dissipation holes 11 and part of the water absorbent 10 is embedded in the heat dissipation holes 11.

[0085] In some embodiments, Fig. 9 and Fig.11 As shown, each collector 6 has a limit rod 62 extending downward, and the limit rod 62 is inserted into the inside of the spring 72 to limit the bending deformation of the spring 72 along its own radial direction; and the limit rod 62 also passes through the corresponding horizontal part and extends out to limit the moving direction and distance of the collector 6.

[0088] The upper side of the guide plate 41 is also provided with an annular groove 412 which is open upwards. The annular groove 412 is located directly below each through hole 23 so as to receive liquid discharged from each through hole 23 .

[0089] The drain pipe 42 is disposed inside the cabinet 1 and located at the lower side of the guide plate 41 .

[0090] Among them, one end of the drain pipe 42 is connected to the bottom of the annular groove 412, and the other end of the drain pipe 42 is located below the guide plate 41, passes through the cabinet 1 and extends out, so that the liquid in the annular groove 412 can be discharged to the outside of the cabinet 1 under the action of its own gravity.
