Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, specifically relating to an outdoor switchgear. Background Technology

[0002] With the comprehensive transformation and development of power transmission, distribution, and transformation networks, the number of switching stations has increased significantly across various regions. Located one level below substations in the power system, switching stations are power facilities that distribute high-voltage electricity to surrounding power-consuming units. They are not only the most basic unit at the bottom of the distribution network but also a crucial link in the transmission of electricity from high voltage to low voltage. A switching station consists of a housing with a door opening. The door is rotatably connected to the housing, and for easy closing, the inner wall of the door opening has a ring-shaped stop that limits the movement of the door.

[0003] Switchgear is typically installed outdoors. The outdoor environment is less stable than the indoor environment. Existing outdoor switchgear usually has a roof that provides some rain protection, but on windy, rainwater will fall at an angle due to the wind. There is a gap between the existing door and the doorway. During prolonged rainfall, the falling rainwater may seep into the cabinet through this gap, creating a damp environment inside and affecting the normal operation of the internal components. Under gravity, the side of the door furthest from its connection to the cabinet will sag, not only affecting the opening and closing of the door but also increasing the gap between the door and the doorway, making it easier for rainwater to penetrate. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an outdoor opening and closing device that prevents rainwater from easily seeping into the interior of the box through the gap between the box door and the door opening during long-term rainfall.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an outdoor opening and closing device, including a box body, the box body having a top cover and a door opening, the door opening having a door rotatably connected to the box body, the inner wall of the door opening having an annular stop, the surface of the stop facing away from the inside of the box body having an annular protrusion, the protrusion having an annular sealing gasket between the annular gasket and the inner wall of the door opening, and the edge of the door having an annular fixing part.

[0006] Using the above solution, the sealing gasket 1 abuts against the inner wall of the protrusion and the door opening under its own elastic force. When the door is closed, the fixing part is located between the protrusion and the inner wall of the door opening, and abuts against the sealing gasket 1. This effectively reduces rainwater seepage between the door and the door opening during prolonged rainy weather.

[0007] As a further feature of this invention, an annular limiting part is provided on the surface of the protrusion facing the inner wall of the doorway, and a sealing gasket is provided between the limiting part and the blocking part.

[0008] By adopting the above solution, the limiting part can prevent the sealing gasket from shifting during use, thus providing a good sealing effect.

[0009] As a further feature of this utility model, the limiting part includes a strip-shaped upper limiting part near the top cover, and the fixing part includes a strip-shaped upper fixing part near the top cover; when the upper fixing part is located on the side of the upper limiting part near the top cover and in contact with the upper limiting part surface, the upper fixing part is parallel to the inner wall of the door opening facing away from the top cover.

[0010] With the above solution, when the door is closed, the upper fixing part and the upper limit part are in contact. The upper limit part can prevent the door from tilting under the action of gravity and ensure that the door opens and closes normally.

[0011] As a further feature of this utility model, the doorway is provided with two mirror-shaped box doors, and a protruding strip and a limiting step that limit the protruding strip are respectively provided between the two box doors. The protruding strip extends away from the top cover, and a sealing gasket is fixed on the surface of the protruding strip facing the limiting step.

[0012] Using the above method, the second sealing gasket can be fixed to the raised strip with adhesive. When the door is closed, the second sealing gasket is tightly attached to the limiting step to prevent rainwater from seeping in from the gap between the two doors.

[0013] As a further feature of this utility model, the fixing part includes side fixing parts located on both sides of the upper fixing part and a lower fixing part parallel to the upper fixing part; when one door is provided in one doorway, the two ends of the side fixing part are respectively connected to the upper fixing part and the lower fixing part; when two doors are provided in one doorway, the two ends of the side fixing part near the inner wall of the doorway are respectively connected to the upper fixing part and the lower fixing part, and there are gaps between the side fixing part near the other door and the upper fixing part, as well as between the side fixing part and the lower fixing part.

[0014] When the above scheme is adopted, if there are two box doors in the doorway, the notch allows the protrusion and the limiting part to pass through, so that when the box doors in the same doorway are closed, the surfaces of the two box doors facing away from the inside of the box are on the same plane.

[0015] As a further feature of this utility model, a plane and an arc-shaped surface are provided between the surface of the upper limit position part facing away from the stop part and the surface of the upper limit position part facing the top cover. The plane is provided between the arc-shaped surface and the surface of the upper limit position part facing away from the stop part. A guide surface is provided between the surface of the upper fixing part facing away from the top cover and the surface of the upper fixing part facing away from the door.

[0016] The above solution facilitates the movement of the upper fixed part and its contact with the upper limit position part.

[0017] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0022] Specific embodiments of this utility model are shown in the accompanying drawings.

[0023] An outdoor switch includes a housing 1 with a doorway 12. A door 2, rotatably connected to the housing 1, is located at the doorway 12. An annular stop 13 is provided on the inner wall of the doorway 12. An annular protrusion 14 is provided on the side of the stop 13 facing away from the interior of the housing 1. An annular sealing gasket 3 is provided between the protrusion 14 and the inner wall of the doorway 12. An annular fixing part is provided at the edge of the door 2. An annular limiting part 15 is provided on the side of the protrusion 14 facing the inner wall of the doorway 12. The sealing gasket 3 is positioned between the limiting part 15 and the stop 13. The sealing gasket 3, under its own elastic force, abuts against the protrusion 14, the limiting part 15, and the inner wall of the doorway 12. The limiting part 15 prevents the sealing gasket 3 from shifting during use, providing a good sealing effect. When the door 2 is closed, the fixing part is located between the protrusion 14 and the inner wall of the door opening 12, and abuts against the sealing gasket 3. This can effectively reduce rainwater seepage between the door 2 and the door opening 12 during prolonged rainy weather.

[0024] In this embodiment, the doorway 12 is provided with two mirror-image cabinet doors 2. A protruding strip 22 and a limiting step 23 forming a limit with the protruding strip 22 are respectively provided between the two cabinet doors 2. The protruding strip 22 extends away from the top cover 11, and a sealing gasket 4 is fixed to the surface of the protruding strip 22 facing the limiting step 23. The sealing gasket 4 is fixed to the protruding strip 22 with adhesive. When the cabinet doors 2 are closed, the sealing gasket 4 is pressed tightly against the limiting step 23 to prevent rainwater from seeping into the gap between the two cabinet doors 2.

[0025] The limiting part 15 includes a strip-shaped upper limiting part 151 near the top cover 11, and the fixing part includes a strip-shaped upper fixing part 211 near the top cover 11, side fixing parts 212 located on both sides of the upper fixing part 211, and a lower fixing part 213 parallel to the upper fixing part 211.

[0026] When the upper fixing part 211 is located on the side of the upper limit position part 151 near the top cover 11 and in contact with the surface of the upper limit position part 151, the upper fixing part 211 is parallel to the inner wall of the door opening 12 facing away from the top cover 11. In this embodiment, when the box door 2 is in the closed state, there is a gap between the box door 2 and the inner wall of the door opening 12 away from the top cover 11, which facilitates the opening and closing of the box door 2. The upper fixing part 211 is in contact with the surface of the upper limit position part 151, and the upper limit position part 151 can prevent the box door 2 from tilting under the action of gravity, ensuring that the box door 2 opens and closes normally.

[0027] A flat surface 152 and an arc-shaped surface 153 are provided between the surface of the upper limit stop 151 facing away from the stop 13 and the surface of the upper limit stop 151 facing the top cover 11. The flat surface 152 is disposed between the arc-shaped surface 153 and the surface of the upper limit stop 151 facing away from the stop 13. A guide surface 2111 is provided between the surface of the upper fixing part 211 facing the lower fixing part 213 and the surface of the upper fixing part 211 facing away from the door 2. This facilitates the upper fixing part 211 to move to contact the surface of the upper limit stop 151.

[0028] In this embodiment, the two ends of the side fixing part 212 near the inner wall of the doorway 12 are connected to the upper fixing part 211 and the lower fixing part 213, respectively. There are gaps 24 between the side fixing part 212 near the other door 2 and the upper fixing part 211, as well as between the side fixing part 212 and the lower fixing part 213. The gaps 24 allow the protrusion 14 and the limiting part 15 to pass through, so that when the doors 2 in the same doorway 12 are closed, the surfaces of the two doors 2 facing away from the inside of the box body 1 are located on the same plane 152.
