Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and particularly relates to an outdoor waterproof distribution cabinet. Background Art

[0002] A distribution cabinet is a power distribution device used for power distribution, control, metering, and connecting cables in a power supply system. In the power system, distribution cabinets play a very important role. They are responsible for distributing the electric energy transmitted by the upper-level power distribution equipment or power source to the nearby loads.

[0003] A large amount of heat is generated by the electrical components in the distribution cabinet during operation. To ensure the heat dissipation of the distribution cabinet, ventilation openings are usually provided on both sides of the distribution cabinet. Therefore, for distribution cabinets used outdoors, the electrical components in the distribution cabinet are likely to get damp in rainy weather.

[0004] Currently, ventilation grooves are generally provided on the side walls of the distribution cabinet. To ensure the waterproof effect of the distribution cabinet in rainy weather, the ventilation grooves are often closed to prevent external rainwater from falling into the distribution cabinet through the ventilation grooves. At the same time, to keep the distribution cabinet dissipating heat in time during operation, the external rainwater is introduced into the distribution cabinet for heat dissipation. However, the existing distribution cabinets still need corresponding improvements.

[0005] Regarding collecting rainwater and flowing it into the distribution cabinet for heat dissipation to prevent external rainwater from entering the distribution cabinet, this protection measure only extends the heat dissipation pipe from the top of the distribution box and from the top or side of the distribution box. For example, in the patent with the publication number CN114122972A, a motor is used to drive the rainwater flow in the heat dissipation pipe. Although it can discharge the rainwater in the heat dissipation pipe, the residence time of the heat dissipation pipe in the distribution cabinet is short, and the rainwater cannot fully absorb the heat in the distribution cabinet, resulting in low heat dissipation efficiency of the distribution cabinet. Content of the Utility Model

[0006] To solve the above technical problems, the utility model solves the technical problem that the heat dissipation pipe at the top or side of the distribution box cannot fully utilize the rainwater to absorb the heat in the distribution cabinet. The specific technical solution is as follows:

[0007] An outdoor waterproof distribution cabinet includes a distribution cabinet. A plurality of air-permeable grooves are formed on the side wall of the distribution cabinet, and a wind baffle is further provided at the air-permeable grooves. The distribution cabinet further includes at least one drain pipe, which is coiled inside the distribution cabinet, and both the top and bottom ends of the drain pipe are located outside the distribution cabinet. Liquid can flow into the drain pipe from the top end and flow out from the bottom end; wherein, the electrical components in the distribution cabinet can be installed on the drain pipe.

[0008] In the above scheme, both the top and bottom ends of the drain pipe are located outside the distribution cabinet. Rainwater flows from the outside of the distribution cabinet into the top of the drain pipe. The rainwater in the drain pipe gradually flows into the distribution cabinet and is separated from the electrical components in the distribution cabinet. The electrical components are installed on the drain pipe to increase the heat dissipation effect of the electrical components when they are working, so that the rainwater absorbs heat but does not evaporate into the distribution cabinet until the rainwater absorbs heat and flows out from the bottom of the drain pipe, completing the heat dissipation effect of the distribution cabinet.

[0009] (1) An extension frame is slidably provided at the top of the power distribution cabinet, and a water storage tank connected to the top of the drain pipe is provided at the top of the extension frame. The water storage tank is used to store water on rainy days so that enough water can flow into the drain pipe, thereby improving the heat dissipation effect of the drain pipe on the power distribution cabinet.

[0010] (2) A butt joint is slidably provided at the top of the drainage pipe, and the butt joint is fixed to the water storage tank. An elastic member is also provided between the power distribution cabinet and the extension frame. The water in the water storage tank presses down on the elastic member, causing the extension frame to move downward, and the bottom end of the butt joint is located at the top of the drainage pipe and overlaps with it. The water in the water storage tank flows into the drainage pipe from the butt joint, and the water in the water storage tank is gradually discharged. The elastic member gradually drives the extension frame and the butt joint to rise by its own elastic force. A fold is also provided around the extension frame, which can shield the elastic member to reduce the contact between rainwater and the elastic member, so as to avoid accelerating the aging of the elastic member.

[0011] (3) A top rod is built into the top of the drainage pipe, and a sealing cap covering the water outlet at the top of the water tank is provided at the top of the top rod; wherein, if the water tank moves downward due to the gravity of the water, the water can flow into the drainage pipe from the water outlet. The elastic member drives the extension frame upward, so that the sealing cap completely covers the water outlet of the water tank, so that the water tank and the drainage pipe are no longer connected, and the rainwater in the water tank is not enough to overcome the supporting force of the elastic member due to its own weight, until the rainwater in the water tank is enough to drive the extension frame downward and press the elastic member downward, at which time the water in the water tank can flow into the water outlet through the gap between the sealing cap and the extension frame.

[0012] (4) The top rod is fixedly connected to the drain pipe.

[0013] (5) A second magnetic ring is installed at the top of the drain pipe, and a first magnetic ring is installed at one end of the top rod facing the second magnetic ring. The first magnetic ring is always under downward pulling force by utilizing the magnetic effect between the first magnetic ring and the second magnetic ring, so that the sealing cap seals the inlet at the top of the water outlet.

[0014] (6) The power distribution cabinet is provided with a cavity at the air permeation groove, and the cavity houses a side plate connected to the extension frame. The side plate is provided with an air permeation groove corresponding to the power distribution cabinet. When the extension frame moves downward under the weight of rainwater, the extension frame drives the side plate to move downward, so that the side plate and the air permeation groove are arranged in an alternating manner, thereby shielding and sealing the air permeation groove of the power distribution cabinet. At the same time, the water in the water storage tank can flow into the drain pipe through the water outlet, and the drain pipe dissipates heat from the electrical components in the power distribution cabinet, ensuring that even on rainy days, the electrical components in the power distribution cabinet can be timely cooled by rainwater.

[0015] (7) The drain pipe has a plurality of bent sections, so as to form a flow channel for the water body to flow inside. Among them, the bent sections of the flow channel can increase the flow travel of the water body and prolong the heat absorption time of the water body in the power distribution cabinet.

[0016] It can be seen from the above technical solutions that the present utility model has the following beneficial effects:

[0017] In this application, a U-shaped drain pipe is provided inside the power distribution cabinet, and the electrical components are arranged on both sides of the U-shaped drain pipe, so as to increase the contact area between the electrical components and the drain pipe. At the same time, the drain pipe is coiled inside the power distribution cabinet, further increasing the travel of rainwater in the power distribution cabinet, enabling the rainwater to fully absorb the heat in the power distribution cabinet and improving the heat dissipation effect on rainy days.

[0018] The power distribution cabinet is provided with an extension frame with a water storage tank, and vertical sliding side plates are arranged on both sides thereof. The top extension frame and the side plates are connected, and the extension frame and the side plates are supported by elastic members. The rainwater in the water storage tank is discharged through the drain pipe. At the same time, the rainwater is used to cool the electrical components in the power distribution cabinet. At the same time, the side plates block the ventilation openings on the sides of the power distribution cabinet, preventing rainwater from entering the power distribution cabinet and cooling the electrical components in the power distribution cabinet on rainy days.

Specific embodiments

[0025] The following combines the accompanying drawings and specific embodiments to elaborate on the present utility model in detail. Before elaborating on the technical solutions of each embodiment of the present utility model, the nouns and terms involved are explained. In this specification, components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0026] As described in the background art, heat dissipation through slots are provided on the power distribution cabinet. In rainy weather, rainwater may enter the interior of the power distribution cabinet through the heat dissipation through slots, causing damage to the components inside the power distribution cabinet.

[0027] To solve this technical problem, the present utility model provides an outdoor waterproof power distribution cabinet, which is applied to the waterproof and heat dissipation of outdoor power distribution cabinets.

[0028] As Figures 1 - 4 shown, an outdoor waterproof power distribution cabinet includes a power distribution cabinet 1. A plurality of ventilation slots 6 are provided on the side wall of the power distribution cabinet 1, and a wind baffle 7 is also provided at the ventilation slots 6. It also includes at least one drain pipe 8, which is coiled inside the power distribution cabinet 1, and both its top and bottom ends are located outside the power distribution cabinet 1. Liquid can flow into the drain pipe 8 from the top end and flow out from the bottom end; wherein, electrical components can be installed on the drain pipe 8. Among them, multiple drain pipes 8 can be provided, or a single drain pipe 8 can be provided. Preferably, multiple drain pipes 8 are provided. If multiple drain pipes 8 are provided, the heat dissipation effect inside the power distribution cabinet 1 can be improved, and at the same time, the electrical components between two adjacent drain pipes 8 can be separated to prevent heat accumulation. The drain pipe 8 is coiled inside the power distribution cabinet 1, and the coiling method increases the flow travel of rainwater inside the drain pipe 8, improving the heat exchange time of the water body inside the power distribution cabinet 1. Specifically, since both the top and bottom ends of the drain pipe 8 are located outside the power distribution cabinet 1, rainwater flows into the top end of the drain pipe 8 from outside the power distribution cabinet 1, and the rainwater inside the drain pipe 8 gradually flows into the power distribution cabinet 1 and is separated from the electrical components inside the power distribution cabinet 1. The electrical components are installed on the drain pipe 8, increasing the heat dissipation effect when the electrical components work, allowing the rainwater to absorb heat but not evaporate into the power distribution cabinet 1 until the rainwater absorbs heat and flows out from the bottom end of the drain pipe 8, completing the heat dissipation effect of the power distribution cabinet 1.

[0029] As Figures 1 - 3As shown in the figure, as an implementation manner in this embodiment, an extension frame 2 is slidably arranged at the top of the power distribution cabinet 1. A water storage tank 4 communicated with the top end of the drain pipe 8 is arranged at the top end of the extension frame 2. Among them, the water storage tank 4 is used to store water bodies in rainy days, so that enough water bodies can flow into the drain pipe 8, improving the heat dissipation effect of the drain pipe 8 on the power distribution cabinet 1.

[0030] As Figures 3 - 5 shown in the figure, since the extension frame 2 slides vertically at the top of the power distribution cabinet 1, in order to ensure that the water body in the water storage tank 4 can smoothly fall into the top end of the drain pipe 8, the following solution is adopted in this application. A docking pipe 13 is slidably arranged at the top end of the drain pipe 8, and the docking pipe 13 is fixed to the water storage tank 4. An elastic member 10 is also arranged between the power distribution cabinet 1 and the extension frame 2. Among them, the elastic member 10 adopts an elastic component, such as a spring, elastic rubber, elastic sheet, or spring telescopic cylinder. Due to the self-weight of the water body in the water storage tank 4, it presses down on the elastic member 10, causing the extension frame 2 to move downward. The bottom end of the docking pipe 13 coincides with the top end of the drain pipe 8. The water body in the water storage tank 4 flows into the drain pipe 8 from the docking pipe 13. The water body in the water storage tank 4 is gradually discharged, and the elastic member 10 gradually drives the extension frame 2 and the docking pipe 13 to rise through its own elastic force. A folded edge is also arranged around the extension frame 2, which can block the elastic member 10 to reduce the contact between rainwater and the elastic member 10, so as to prevent the acceleration of the aging of the elastic member 10. To ensure the service life of the elastic member 10, a spring or spring telescopic cylinder is adopted in this application. In addition to using the docking pipe 13, the docking pipe 13 can also be replaced with a flexible water pipe, and the flexible water pipe directly connects the water outlet of the water storage tank 4 to the top end of the drain pipe 8. Whether the extension frame 2 moves downward along the vertical direction or not, the water storage tank 4 is always communicated with the drain pipe 8.

[0031] As Figures 3 - 5 shown in the figure, as an implementation manner in this embodiment, a top rod 12 is built into the top end of the drain pipe 8, and a sealing cap 5 covering the top water outlet 11 of the water storage tank 4 is arranged at the top end of the top rod 12; among them, if the water storage tank 4 moves downward under the gravity of the water body, the water body can flow into the drain pipe 8 from the water outlet 11. Among them, the sealing cap 5 is circular and its size is larger than the water outlet 11. When the elastic member 10 drives the extension frame 2 to move upward, the sealing cap 5 completely blocks the water outlet 11 of the water storage tank 4, making the water storage tank 4 no longer communicate with the drain pipe 8. That is, in the gentle rain, the rainwater in the water storage tank 4 is not enough to overcome the supporting force of the elastic member 10 due to its own weight until the rainwater in the water storage tank 4 is enough to drive the extension frame 2 to move downward and press down on the elastic member 10. At this time, the water body in the water storage tank 4 can flow into the water outlet 11 through the gap between the sealing cap 5 and the extension frame 2, and the drain pipe 8 is filled with water body, that is, the heat dissipation in the power distribution cabinet 1 is realized.

[0032] As Figures 3 - 5As shown, as an implementation manner in this embodiment, the power distribution cabinet 1 is provided with a cavity at the air permeable groove 6, and the cavity houses a side plate 9 connected to the extension frame 2. The side plate 9 is provided with an air permeable groove 6 corresponding to the power distribution cabinet 1. Among them, when the extension frame 2 moves downward under the weight of rainwater, the extension frame 2 drives the side plate 9 to move downward, so that the side plate 9 and the air permeable groove 6 are staggered, thereby blocking and sealing the air permeable groove 6 of the power distribution cabinet 1. At the same time, the water body in the water storage tank 4 can flow into the drain pipe 8 through the water outlet 11, so that the drain pipe 8 dissipates heat from the electrical components in the power distribution cabinet 1, ensuring that even on rainy days, the electrical components in the power distribution cabinet 1 can be dissipated heat in time by rainwater.

[0033] As Figure 4 shown, as an implementation manner in this embodiment, the ejector rod 12 is fixedly connected to the drain pipe 8. Among them, there are various installation methods for the ejector rod 12, but as long as it is ensured that the ejector rod 12 is fixed at the top of the drain pipe 8. For this application, the ejector rod 12 and the drain pipe 8 can adopt the fixing methods of threading, clamping, gluing and welding. However, to ensure that the ejector rod 12 is detachable and increase its service life to avoid rust, the magnet adsorption method is preferably adopted. The specific scheme is as follows: a second magnetic ring 15 is installed at the top end of the drain pipe 8, and a first magnetic ring 14 is provided at one end of the ejector rod 12 facing the second magnetic ring 15. By using the magnetic action between the first magnetic ring 14 and the second magnetic ring 15, the first magnetic ring 14 is always under a downward pulling force, so that the sealing cap 5 seals the inlet at the top of the water outlet 11. In rainy weather, when the water storage tank 4 receives enough rainwater and the whole water storage tank 4 descends, through the supporting action of the second magnetic ring 15 on the first magnetic ring 14, the docking pipe 13 directly sinks into the inside of the drain pipe 8, and the sealing cap 5 moves away from the inlet of the water outlet 11. At this time, the rainwater will enter the inside of the drain elbow 8 through the water outlet 11.

[0034] As Figure 5 shown, as an implementation manner in this embodiment, the drain pipe 8 has a plurality of bent sections, so that a flow channel for the water body to flow is formed inside. The drain pipe 8 of this application can adopt a snake shape, an S shape, a U shape, a Z shape or a spiral shape, and it has a plurality of bent shapes to increase the travel of rainwater in the drain pipe 8 and improve the heat dissipation effect of the water body on the electrical components in the power distribution cabinet 1.

[0035] As an implementation manner in this embodiment, a drain hole 16 communicating with the bottom end of the drain pipe 8 is provided at the bottom end of the power distribution cabinet 1. For the drain pipe 8, a single water inlet can be provided at its top end, or multiple water inlets can be provided. And the drain hole 16 at its bottom end can also be provided as a single one or multiple ones, so that the water body falls due to gravity in the drain pipe 8 without a driving source, reducing energy consumption.

[0036] As an implementation mode in this embodiment, a rotating cabinet door 3 is installed on the front of the power distribution cabinet 1. After the cabinet door 3 is closed, it is sealed on the front of the power distribution cabinet 1, playing a protective role for the front of the power distribution cabinet 1, preventing people other than the staff from opening it, and at the same time preventing rainwater from entering it in rainy weather.

[0037] On sunny days, the ventilation slots 6 opened on both sides of the power distribution cabinet 1 can normally conduct ventilation and heat dissipation. At this time, the wind baffle 7 arranged outside the ventilation slots 6 always remains open under the action of the torsion spring. In windy weather, when strong wind blows to the side of the power distribution cabinet 1 and acts on the surface of the wind baffle 7, the wind baffle 7 will directly close, thereby preventing the strong wind from sending dust into the interior of the power distribution cabinet 1.

[0038] In rainy weather, when the rain is heavy, an extension frame 2 is provided at the top of the power distribution cabinet 1, and vertical sliding side plates 9 are provided on both sides thereof. The top extension frame 2 and the side plates 9 are connected, and the extension frame 2 and the side plates 9 are supported by elastic members 10. A U-shaped drain pipe 8 is provided inside the power distribution cabinet, and the electrical components are arranged on both sides of the U-shaped drain pipe 8. In rainy weather, when too much rainwater accumulates in the water storage tank 4, the water storage tank 4 will drop due to the gravity of the rainwater, so that the water outlet 11 of the water storage tank 4 is communicated with the top of the drain pipe. At the same time, the ventilation slots 6 on the side of the power distribution cabinet 1 are blocked by the side plates 9, so that the rainwater in the water storage tank 4 is discharged through the drain pipe 8, and at the same time, the rainwater is used to cool the electrical components in the power distribution cabinet 1. In rainy weather, it prevents rainwater from entering the power distribution cabinet 1 and at the same time cools the electrical components in the power distribution cabinet 1.

[0039] The above-described implementation modes are only descriptions of the preferred implementation modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
