Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and specifically to a distribution cabinet capable of reducing external pollution. Background Technique

[0002] A distribution cabinet is an electrical device integrating switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment, which realizes the distribution and management of electric energy through a standardized wiring scheme and is widely used in industries, buildings, medical care, transportation and other fields.

[0003] Among them, the distribution cabinets installed in communities and outdoors are designed specifically for outdoor environments and are used for distributing, controlling, and protecting the electricity consumption of residents and public facilities. Its core feature is to adapt to complex outdoor environments, ensure the safety and stability of community power supply, avoid low-lying waterlogged areas and green belts (to prevent plant roots from damaging cables), reserve a maintenance passage of more than 1 meter, and secondly, a concrete base is generally poured at the bottom of the distribution cabinet, and a cable trench or conduit is reserved and connected to the underground cable network.

[0004] Existing outdoor distribution cabinets in communities need to be maintained regularly. After extreme weather such as heavy rain, it is necessary to check whether the cabinet body has entered water. However, there is no good way to block rainwater during rain, and a certain amount of rainwater will enter the cabinet. Secondly, during the rainfall caused by the strong upward convection of air due to the ground heating in summer, the temperature inside the cabinet is generally relatively high, and there is no good way to cool the inside of the cabinet during the rain. Summary of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0034] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0035] Please refer to Figures 1 - 8, including a distribution box housing 1, with a driving motor 3 on the inner wall of the distribution box housing 1, and second screws 30 and rotating rods 31 are arranged at both ends of the driving motor 3. A belt 32 is arranged at the top of the rotating rod 31, and a limiting component 2 for guiding rainwater is arranged at the other end of the belt 32. The limiting component 2 includes a first screw 20, a nut 21, and a connecting rod 22. One end of the connecting rod 22 is provided with a contact block 23, and a limiting plate 27 is arranged at the top of the contact block 23. A sealing ring 24 is sleeved on the outer wall of the contact block 23, and a sleeve 25 is sleeved at the bottom of the sealing ring 24. One end of the limiting plate 27 is provided with a fixing block 4, and a first downpipe 41 is installed at the bottom of the fixing block 4, and a plurality of second downpipes 42 are arranged at the bottom of the first downpipe 41. The outer wall of the second screw 30 is sleeved with a belt 32, and a baffle 33 is installed at the bottom of the belt 32. Through the setting of the limiting component 2, the rainwater on the top of the distribution box housing 1 is guided, so that the rainwater passes through the first downpipe 41 and the second downpipes 42 and flows out from the water outlet pipe 14. Through the setting of the positions of the plurality of first downpipes 41 and the second downpipes 42, the periphery of the distribution box housing 1 is cooled, effectively collecting and discharging the rainwater. Secondly, it is also convenient for the owners or property management in the community to use external tools to collect and reuse the rainwater, reducing the waste of water resources. Through the setting of the baffle 33, the driving motor 3 drives the second screw 30 to rotate, so that the sleeve 36 and the connecting plate 34 drive the baffle 33 to move, blocking the air outlet 11, reducing the flow of air volume, and also reducing the possibility of rainwater entering the equipment, and can also reduce the entry of external impurities into the equipment, improving the service life of the equipment. Through the setting of the fixing frame 12, the fixing frame 12 is arranged on the outer wall of the distribution box housing 1 and the fixing frame 12 is located at the top of the water outlet pipe 14, and a receiving pipe 13 is arranged in the fixing frame 12. The receiving pipe 13 is communicated with the water outlet pipe 14, so that the rainwater in the fixing frame 12 flows into the water outlet pipe 14 from the receiving pipe 13 and converges with the rainwater of the first downpipe 41 and the second downpipes 42, reducing the accumulation of rainwater at the bottom of the distribution box housing 1, thereby extending the service life of the distribution box housing 1 and also reducing the workload of the staff for repairing and cleaning the rainwater.

[0036] In the above embodiment, specifically, please refer to again Figures 3 - 5 , a sleeve 36 is sleeved at the bottom of the second screw 30, and a connecting plate 34 is installed at the bottom of the sleeve 36. The connecting plate 34 is U-shaped, and a piston rod 35 is installed at the lower end of the baffle 33 at the other end of the connecting plate 34, and the bottom of the piston rod 35 is connected to the inner wall of the distribution box housing 1. The driving motor 3 drives the second screw 30 to rotate, so that the sleeve 36 drives the connecting plate 34 and the baffle 33 to move downward. The baffle 33 moves to one end of the air outlet 11, and the shape of the connecting plate 34 effectively enables the two baffles 33 to move synchronously.

[0037] In the above embodiment, specifically, please refer to againFigure 4 、 Figure 5 Both ends of the connecting plate 34 are provided with protrusions, and the inner wall of the distribution box shell 1 is provided with grooves, and the protrusions are engaged with the grooves on the inner wall of the distribution box shell 1. The engagement of the protrusions with the grooves on the inner wall of the distribution box shell 1 effectively improves the stability of the connecting plate 34 during movement, reduces the shaking generated during the movement of the connecting plate 34, and thereby improves the service life of the component.

[0038] In the above embodiment, please refer to Figures 1 - 5 A top cover 10 is provided on the top of the distribution box housing 1, and exhaust ports 11 are provided at both ends of the distribution box housing 1, and limit plates 27 and fixing blocks 4 are provided around the top cover 10. The top cover 10 is diamond-shaped, and the shape of the top cover 10 is used to better guide rainwater, so that rainwater flows into the top of the limit plate 27. The contact block 23 pulls the limit plate 27 to make the limit plate 27 sloped, which gathers rainwater and reduces the accumulation of rainwater on the surface of the top cover 10.

[0039] In the above embodiment, please refer to Figures 1 - 6 There are four groups of limit plates 27 and fixed blocks 4, and one end of the limit plate 27 is movably connected to the top cover 10, and a contact block 23 is provided at the bottom of the other end of the limit plate 27. The rotation of the first screw 20 drives the nut 21 to move downward, thereby causing the multiple groups of connecting rods 22 to move downward, driving the contact block 23 to move downward, so that the limit plate 27 is sloped. Secondly, the limit plate 27 is connected to the end of the fixed block 4 away from the through hole 40 through a torsion spring.

[0040] In the above embodiment, please refer to Figure 5 、 Figure 6 and Figure 8 The end of the limiting plate 27 close to the contact block 23 contacts the outer wall of the fixed block 4, and the end of the fixed block 4 close to the limiting plate 27 is provided with a through hole 40, and the bottom of the fixed block 4 is also provided with a through hole 40. Through the setting of the through hole 40, rainwater on the surface of the limiting plate 27 flows from the limiting plate 27 into the fixed block 4, and then flows into the first downpipe 41 and the second downpipe 42 through the diversion of the through hole 40, effectively collecting the rainwater, and also dissipating the heat of the inner wall of the distribution box shell 1 appropriately, thereby reducing the temperature inside the distribution box shell 1.

[0041] In the above embodiment, please refer to Figures 4 - 6, a first downpipe 41 is installed at the bottom of the fixed block 4, and a plurality of second downpipes 42 are installed at the lower end of the first downpipe 41, and the second downpipes 42 and the first downpipe 41 are communicated with each other. One end of the first downpipe 41 is provided with a hose 26, and the other end of the hose 26 is connected to the bottom of the sleeve 25. The first downpipe 41 is a longitudinal water pipe, and the second downpipe 42 is a transverse water tank, and the bottom of the communication between the first downpipe 41 and the second downpipe 42 is solid. Through the arrangement of the first downpipe 41 and the second downpipe 42, rainwater is collected centrally, and the solid bottom of the connection between the first downpipe 41 and the second downpipe 42 also effectively improves the stability of the first downpipe 41 on the inner wall of the distribution box housing 1. Secondly, the arrangement of the hose 26 also reduces the possibility of rainwater flowing into the distribution box housing 1.

[0042] In the above embodiment, specifically, please refer to Figures 4 - 6 , the heights of the plurality of second downpipes 42 are not on the same horizontal plane, and a water outlet pipe 14 is provided at the lowest point where the second downpipe 42 and the first downpipe 41 intersect. Through the different height settings of the second downpipe 42, the water on the inner wall of the first downpipe 41 is guided, so that the rainwater in the plurality of first downpipes 41 flows out from the water outlet pipe 14, which is convenient for the secondary utilization of rainwater.

[0043] In the above embodiment, specifically, please refer to Figures 2 - 5 , the driving motor 3 is a double-headed motor, and a baffle 33 and a connecting plate 34 are fixedly installed at the bottom of the sleeve 36. A plurality of through holes are provided in the inner wall of the baffle 33, and the through holes are arranged opposite to the air outlet 11. The model of the driving motor 3 is a double-headed micro low-speed permanent magnet synchronous motor with a forward and reverse function, so that the second screw 30 and the rotating rod 31 move synchronously, improving the working efficiency of the equipment. While the assembly blocks the rainwater, it also effectively collects the rainwater.

[0044] In the above embodiment, specifically, please refer to Figures 2 - 6 , the first screw 20 is movably connected to the inner wall of the distribution box housing 1, and a connecting rod 22 is sleeved on the outer wall of the first screw 20, and the connecting rod 22 meshes with the first screw 20. One end of the first screw 20 is sleeved with a belt 32, and the other end of the belt 32 is provided with a rotating rod 31. The first screw 20 and the distribution box housing 1 are connected by a bearing, and driven wheels are provided at both ends of the belt 32. The rotation of the first screw 20 is driven by the belt 32, so that a plurality of connecting rods 22 move, converting kinetic energy and saving energy consumption.

[0045] Please refer to Figure 2 , Figure 7, the difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, a fixing frame 12 is added to the outer wall of the distribution box housing 1 to collect the rainwater on the outer wall of the distribution box housing 1 and reduce the accumulation of rainwater at the bottom of the distribution box housing 1.

[0046] A fixing frame 12 is arranged on the outer wall of the distribution box housing 1, and a receiving pipe 13 is installed in the fixing frame 12. The bottom of the receiving pipe 13 is connected to the top of the water outlet pipe 14. The inside of the fixing frame 12 is inclined, and the receiving pipe 13 is located at the lowest position on the inner wall of the fixing frame 12. Secondly, one end of the top of the fixing frame 12 in contact with the distribution box housing 1 is in a slope shape. The fixing frame 12 effectively guides the rainwater flowing down the outer wall of the distribution box housing 1, reduces the rainwater flowing into the bottom of the distribution box housing 1, and further reduces the accumulation amount of rainwater at the bottom of the distribution box housing 1, thereby prolonging the service life of the distribution box housing 1.

[0047] When the present invention is working specifically: When the outdoor power distribution cabinet placed in the community encounters rainy days, the induction system in the equipment senses the rainwater, starts the driving motor 3 to drive the second screw rods 30 and the rotating rods 31 at both ends of the driving motor 3 to rotate synchronously. The second screw rod 30 drives the sleeve 36 to move downward, thereby driving the baffle 33 and the connecting plate 34 to move downward to block the air outlets 11 at both ends of the distribution box housing 1, greatly reducing the rainwater entering the cabinet. At the same time, the rotation of the rotating rod 31 drives the rotation of the belt 32, causing the first screw rod 20 to rotate and drive the nut 21 and the connecting rod 22 to move downward. Furthermore, the contact block 23 drives the limiting plate 27 to move downward. The limiting plate 27 is in a slope shape, so that the rainwater on the limiting plate 27 and the outer wall of the top cover 10 flows into the through hole 40. The through hole 40 is communicated with the first water outlet pipe 41. Through the setting of the angles of multiple groups of the first water outlet pipes 41 and the second water outlet pipes 42, the rainwater is gathered together and flows out from the water outlet pipe 14, which is convenient for transferring the water on the top of the top cover 10, reducing the accumulation of rainwater at the top cover 10, prolonging the service life of the distribution box housing 1. Secondly, it is also convenient for residents to use external tools to collect the rainwater for secondary utilization of the rainwater, reducing the waste of water resources; Furthermore, a sealing ring 24 is sleeved on the outer wall of the contact block 23, and a sleeve 25 is sleeved at the bottom of the sealing ring 24. One end of the sleeve 25 is provided with a hose 26. Secondly, the other end of the hose 26 is connected to the first water outlet pipe 41. When the sealing ring 24 ages and leaks water after long-term use, the sleeve 25 transfers the amount of water seeping from the bottom of the contact block 23 through the setting of the hose 26, reducing the possibility of rainwater entering the equipment; Furthermore, a fixed frame 12 is provided on the outer wall of the distribution box housing 1. One end of the fixed frame 12 is provided with a receiving pipe 13, and the bottom of the receiving pipe 13 is connected to the top of the water outlet pipe 14 to collect the rainwater in the fixed frame 12. The tight fit between the distribution box housing 1 and the fixed frame 12 effectively collects the rainwater flowing down the outer wall of the distribution box housing 1, reduces the amount of rainwater flowing into the bottom of the distribution box housing 1, and thus improves the service life of the distribution box housing 1.
