[0030] Reference is made to Figures 1 to 6As shown, the embodiment provides an electric box, which comprises a box body 10 and a box door 20, the front end of the box body 10 is provided with an opening, and the box door 20 is installed on the box body 10 to open or close the opening; the box body 10 comprises a water guide inclined top plate 11 and a bottom plate 12, the water guide inclined top plate 11 is arranged at an angle between the bottom plate 12, along the height direction of the box body 10, the front end of the water guide inclined top plate 11 is higher than the rear end of the water guide inclined top plate 11; the two side edges of the water guide inclined top plate 11 are provided with first water retaining edges 111, and the front side edge of the water guide inclined top plate 11 is provided with a second water retaining edge 112, the second water retaining edge 112 is connected between the two first water retaining edges 111, and the first water retaining edge 111 and the second water retaining edge 112 extend away from the bottom plate 12 from the water guide inclined top plate 11 to enclose a water guide groove with the top plate.

[0031] The electric box provided by the embodiment, because the two side edges of the water guide inclined top plate 11 are provided with the first water retaining edges 111, the front side edge of the water guide inclined top plate 11 is provided with the second water retaining edge 112, and the first water retaining edge 111 and the second water retaining edge 112 extend away from the bottom plate 12 from the water guide inclined top plate 11, so that the first water retaining edge 111, the second water retaining edge 112 and the water guide inclined top plate 11 enclose the water guide groove, and the water guide inclined top plate 11 serves as the groove bottom of the water guide groove, because along the height direction of the box body 10, the front end of the water guide inclined top plate 11 is higher than the rear end of the water guide inclined top plate 11, when rainwater or other liquid falls on the water guide inclined top plate 11, the rainwater can flow to the rear end of the box body 10 along the water guide groove, at the same time, the setting of the second water retaining edge 112 can reduce the risk of rainwater entering the inside of the box body 10 from the gap between the box door 20 and the box body 10, and the safety is improved.

[0032] For example, the water guide inclined top plate 11 can be a rectangular plate, one side edge of the water guide inclined top plate 11 close to the box door 20 is the front side edge of the water guide inclined top plate 11, and the side edge opposite to the front side edge is the rear side edge. The front end of the water guide inclined top plate 11 is higher than the rear end of the water guide inclined top plate 11, that is, the front side edge of the water guide inclined top plate 11 is higher than the rear side edge.

[0033] In the embodiment, referring to Figure 1 As shown, the box body 10 further comprises a first side plate 13 and a second side plate 14, the first side plate 13 and the second side plate 14 are connected between the water guide inclined top plate 11 and the bottom plate 12, the first side plate 13 and the second side plate 14 are oppositely arranged, the first water retaining edges 111 arranged on the two side edges of the water guide inclined top plate 11 are respectively a first sub-edge 111a and a second sub-edge 111b, and along the arrangement direction of the first side plate 13 and the second side plate 14, the first side plate 13 and the second side plate 14 are located between the first sub-edge 111a and the second sub-edge 111b.

[0034] The first side plate 13 and the second side plate 14 are each provided with a plurality of through holes. Exemplarily, a part of the through holes on the first side plate 13 can be air inlets, and another part of the through holes can be used for mounting cable joints and the like; a part of the through holes on the second side plate 14 can be air outlets, and another part of the through holes can be used for mounting cable joints and the like.

[0035] In the embodiment, the first water-blocking edge 111 arranged on the side of the water guide inclined roof plate 11 close to the first side plate 13 is named as a first sub-edge 111a, and the first water-blocking edge 111 arranged on the side of the water guide inclined roof plate 11 close to the second side plate 14 is named as a second sub-edge 111b. Along the arrangement direction of the first side plate 13 and the second side plate 14, the first side plate 13 and the second side plate 14 are located between the first sub-edge 111a and the second sub-edge 111b. In this way, the connection between the cable joints and the like and the cabinet 10 and the gap between the two sides of the cabinet 10 and the cabinet door 20 can be effectively blocked, and the risk of rainwater entering the inside of the cabinet 10 is reduced.

[0036] In an embodiment, as shown in Figure 4 The distance D1 between the first sub-edge 111a and the first side plate 13 is 15-40 mm, and the distance D2 between the second sub-edge 111b and the second side plate 14 is 15-40 mm. In this way, the connection between the cable joints and the like and the cabinet 10 and the gap between the two sides of the cabinet 10 and the cabinet door 20 can be effectively blocked, and the risk of rainwater entering the inside of the cabinet 10 is reduced, and the external volume of the electric cabinet is not significantly increased.

[0037] It should be understood that the distance between the first sub-edge 111a and the first side plate 13 and the distance between the second sub-edge 111b and the second side plate 14 can be equal or not equal.

[0038] It should be noted that the first sub-edge 111a and the first side plate 13 can be coplanar, and the second sub-edge 111b and the second side plate 14 can also be coplanar.

[0039] In an embodiment, as shown in Figure 2 The second water-blocking edge 112 includes a first edge 1121 and a second edge 1122. The first edge 1121 is connected with the front side of the water guide inclined roof plate 11, and the second edge 1122 is connected with the side of the first edge 1121 away from the water guide inclined roof plate 11. The second edge 1122 is arranged at an obtuse angle with the first edge 1121, and extends from the end connected with the first edge 1121 to the direction close to the rear side of the cabinet 10.

[0040] Exemplarily, the second water-blocking edge 112 and the water guide inclined roof plate 11 can be integrally formed, or can be welded. The first edge 1121 and the second edge 1122 can be integrally formed, or can be welded.

[0041] Due to the obtuse angle between the second edge 1122 and the first edge 1121, and the second edge 1122 extending from the end connected with the first edge 1121 to the direction close to the rear side of the cabinet 10, when rain falls on the second edge 1122, the inclined second edge 1122 can guide the rain to fall along the second edge 1122 away from the cabinet door 20, reducing the risk of rain flowing directly into the gap between the cabinet 10 and the cabinet door 20.

[0042] In an embodiment, the front side of the water guide inclined roof plate 11 protrudes from the front side surface of the cabinet door 20, which can block the gap between the upper edge of the cabinet door 20 and the cabinet 10, avoiding water flowing into the cabinet 10 from the gap. For example, the distance between the front side of the water guide inclined roof plate 11 and the front side surface of the cabinet door 20 is 15-35 mm. The relevant description in the embodiment is by default under the condition that the cabinet door 20 is closed.

[0043] In the embodiment, the front side of the water guide inclined roof plate 11 protrudes from the front side surface of the cabinet door 20, and the two sides of the water guide inclined roof plate 11 protrude from the first side plate 13 and the second side plate 14, which can block water from above and both sides of the cabinet 10, effectively blocking the connection between the cable joint and the cabinet 10 and the gap between the two sides of the cabinet 10 and the cabinet door 20, and at the same time, guiding the water to the rear end of the cabinet 10 through the water guide groove, reducing the risk of rain entering the cabinet 10.

[0044] For example, the electrical cabinet provided in the embodiment can be installed outdoors, or inside and / or outside a mobile device such as a boarding bridge.

[0045] In an embodiment, referring to Figure 1 As shown, the cabinet door 20 is provided with a sealing member 24 for sealing the gap between the cabinet door 20 and the cabinet 10, and the upper edge of the cabinet door 20 is provided with a first folded edge 21 located above the sealing member 24.

[0046] For example, the first folded edge 21 is generally parallel to the bottom plate 12 of the cabinet 10, and the first folded edge 21 can be bent from the edge of the cabinet door 20. The first folded edge 21 is located above the sealing member 24, which can block the sealing member 24 to prevent rain from directly entering the sealing part of the sealing member 24 and the cabinet.

[0047] For example, the sealing member 24 can be foamed glue or a sealing ring.

[0048] In an embodiment, referring to Figure 5 and Figure 6As shown, the opening edge of the cabinet 10 is provided with an outward flange 15, which is bent to form a drainage groove; the cabinet door 20 further comprises a second flange 22, which is connected with the first flange 21 and is located on the side of the sealing member 24 away from the cabinet door 20; the second flange 22 is used to guide water to the drainage groove; the lower edge of the cabinet door 20 is provided with a third flange 23, which is opposite to the first flange 21, and the third flange 23 is provided with a drainage hole 231, which is in communication with the drainage groove.

[0049] Specifically, the shape of the opening can be rectangular, and the outward flange 15 is formed around the opening. The outward flange 15 is in the shape of a bent plate, and the side of the outward flange 15 away from the opening forms a drainage groove. For example, referring to Figure 6 As shown, the drainage groove comprises a first transverse groove segment 151, a second transverse groove segment 152, and two vertical groove segments 153; the groove opening of the first transverse groove segment 151 faces the water guide inclined roof plate 11, the groove opening of the second transverse groove segment 152 is away from the water guide inclined roof plate 11, and the groove openings of the two vertical groove segments 153 are opposite and connected at the two ends of the first transverse groove segment 151 and the second transverse groove segment 152, respectively. For example, referring to Figure 1 As shown, the number of drainage holes 231 can be two, which correspond to the two vertical groove segments 153, respectively.

[0050] For example, the second flange 22 is generally perpendicular to the first flange 21, and the length of the second flange 22 is 5-20 mm along the height direction of the cabinet 10.

[0051] When the cabinet door 20 is in a closed state, the second flange 22 can be located above the first transverse groove segment 151, and the third flange 23 is located below the second transverse groove segment 152; if rainwater enters the gap between the cabinet door 20 and the cabinet 10, the rainwater will flow into the first transverse groove segment 151 along the second flange 22, then flow downward along the vertical groove segments 153 to the third flange 23, and then be discharged to the outside of the electrical cabinet through the drainage hole 231, thereby reducing the water accumulation at the bottom of the cabinet door 20.

[0052] For example, the cabinet door 20, the first flange 21, the second flange 22, and the third flange 23 are integrally formed.

[0053] For example, the drainage hole 231 can be a rectangular hole, and the length of the rectangular hole can be 18 mm and the width can be 8 mm.

[0054] In some embodiments, the depth of the drainage groove is relatively deep, which can block the rainwater from flowing to the sealing position of the sealing member 24 and the cabinet 10 to some extent, thereby reducing the waterproof problem of the sealing member 24 after aging.

[0055] In an embodiment, a gap is provided between the lower surface of the sealing member 24 and the third flange 23, which can reduce the contact between the sealing member 24 and the accumulated water.

[0056] For example, the distance between the lower surface of the sealing member 24 and the third fold 23 is 3-15 mm. In this way, not only can the contact between the sealing member 24 and the accumulated water be reduced, but also the opening of the box body 10 can be ensured to be large enough, and the size of the opening in the height direction of the box body 10 will not be significantly reduced due to the change of the position of the sealing member 24.

[0057] It should be noted that the first fold 21, the second fold 22 and the third fold 23 can be provided at the same time, as shown in Figure 5 It should be noted that the first fold 21, the second fold 22 and the third fold 23 can be provided at the same time, as shown in Figure 1 It should be noted that the first fold 21, the second fold 22 and the third fold 23 can be provided at the same time, as shown in

[0058] In an embodiment, the angle between the water guide inclined roof plate 11 and the bottom plate 12 is 2-10°. In this way, not only can a better drainage effect be achieved, but also the overall height of the box body 10 will not be significantly increased, and the internal space of the box body 10 will not be compressed due to the limitation of the height size.

[0059] Referring to Figure 3 It should be noted that the first fold 21, the second fold 22 and the third fold 23 can be provided at the same time, as shown in

[0060] In an embodiment, referring to Figure 3 It should be noted that the first fold 21, the second fold 22 and the third fold 23 can be provided at the same time, as shown in

[0061] In an embodiment, the electrical box further comprises a hinge (not shown in the figure), the hinge is welded with the box body 10, and the box door 20 is rotationally connected with the box body 10 through the hinge. By welding the hinge, the risk of water entering the box body 10 can be reduced.

[0062] For example, the hinge comprises a mounting portion and a pin shaft, the mounting portion is provided with a insertion hole; a sleeve is welded on one side of the box door 20 which is connected with the hinge, the sleeve is in communication with the insertion hole, the pin shaft is arranged in the insertion hole and the sleeve, and the box door 20 can rotate around the axis of the pin shaft relative to the box body 10 to open or close the opening of the box body 10.

[0063] It should be noted that the box body 10 can further comprise an inner roof plate, the inner roof plate is located below the water guide inclined roof plate 11, and the inner roof plate is fixedly connected between the first side plate 13 and the second side plate 14. The inner roof plate can be parallel to the bottom plate 12.

[0064] The embodiment also provides a boarding bridge, which comprises the electric box provided by the embodiment. The electric box can be installed inside or outside the boarding bridge. When the number of the electric boxes is multiple, the multiple electric boxes can be simultaneously installed inside or outside the boarding bridge, or a part of the electric boxes can be installed inside the boarding bridge and the other part of the electric boxes can be installed outside the boarding bridge.

[0065] The boarding bridge provided by the embodiment can reduce the risk of rainwater or other liquid entering the inside of the box body 10 from the gap between the box door 20 and the box body 10, and improve the safety, because the electric box provided by the embodiment is used, when rainwater or other liquid falls on the water guide inclined roof plate 11 of the electric box, the rainwater or other liquid can flow to the rear end of the box body 10 along the water guide groove, and the second water blocking edge 112 can reduce the risk of rainwater or other liquid entering the inside of the box body 10 from the gap between the box door 20 and the box body 10.
