If the specific posture changes, the directional indication will also change accordingly.

[0026] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0027] The present embodiment discloses a waterproof structure, which is mainly used for various boxes, cabinets and other equipment with storage space inside, specifically some boxes, cabinets and the like for placing live equipment, such as energy storage cabinets, so that the outside of these boxes, cabinets and other equipment can be effectively waterproofed, especially in boxes and cabinets with structures such as switch doors, the waterproof structure can effectively prevent external water from entering through the gaps of the switch doors.

[0028] The waterproof structure of this embodiment is preferably suitable for boxes, cabinets, etc. in a rectangular shape.

[0029] For details, please refer to the following Figure 1As shown, the waterproof structure includes a column 2, a first plate 12 and a second plate 11. The column 2 is a columnar structure and is arranged in a vertical direction in space. The column 2 can be of any shape, but should include at least one vertical edge on its circumference, and the two sides of the edge are respectively a first side wall 21 and a second side wall 22. In this embodiment, the column 2 is preferably a columnar structure with a rectangular cross-section, and its circumference has four edges, and the two sides of one edge are respectively the first side wall 21 and the second side wall 22 which are perpendicular to each other.

[0030] The first plate 12 and the second plate 11 correspond to the first side wall 21 and the second side wall 22 respectively. The first plate 12 is parallel to the first side wall 21, and the second plate 11 is parallel to the second side wall 22 and abuts against the second side wall 22. The first plate 12 is perpendicular to the second plate 11, and one side of the second plate 11 connected with the first plate 12 extends forward so as to be flush with the front side of the second plate 11. Figure 1 The ab direction shown in represents the front-back direction.

[0031] The waterproof structure in this embodiment is based on the situation that the connection position between the first plate 12 and the second plate 11 cannot be completely closed. In actual application, this situation may be due to process limitations, and the first plate 12 and the second plate 11 cannot be completely seamless, or because the first plate 12 is set as a switch and is movable. In the case of being movable, a gap needs to be reserved to avoid interference. The above situations are all summarized as the situation where there is a gap between the first plate 12 and the second plate 11, and the waterproof structure is used to deal with water entering from the gap to prevent the water from further penetrating.

[0032] The first plate 12, the first side wall 21, the second side wall 22 and the second plate 11 are mutually surrounded to form a waterproof channel, and the waterproof channel is connected in the vertical direction. The setting of the waterproof channel is to maintain the water entering from the gap from the outside in the waterproof channel and prevent the water from further penetrating into other positions, so as to achieve a waterproof effect.

[0033] The end of the first plate 12 near the second plate 11 is bent backward, and the bending angle is preferably ninety degrees. The bent part is parallel to the second plate 11 and spaced apart by a certain distance, forming a first flow channel 13 with a certain length in the front-rear direction. The setting of the first flow channel 13 is essentially equivalent to the above-mentioned gap. On the one hand, if the first plate 12 is movably arranged in a specific application, for example, the first plate 12 is set as a switchable first plate 12, then the bent part of the first plate 12 will not interfere with the second plate 11 during its opening and closing. On the other hand, when water enters the first flow channel 13, the left and right side walls of the first flow channel 13 will adsorb most of the water and guide the water to flow downward along the left and right side walls instead of penetrating inward.

[0034] Since the angle, amount, and force of the water entering the first flow channel 13 from the outside are all uncertain factors, the first flow channel 13 cannot isolate all the invading rainwater. Further, a baffle 111 is extended and provided on the second plate 11. The baffle 111 is located at the rear side of the first flow channel 13 and is perpendicularly arranged to the first flow channel 13, so that the rear end of the first flow channel 13 forms a ninety-degree bend, and then the baffle 111 blocks the water further invading into the first flow channel 13, making the water flow downward along the baffle 111.

[0035] When the amount of water entering is too large and both the first flow channel 13 and the baffle 111 cannot prevent the further penetration of water, the water entering at this time may come into contact with the first side wall 21 and flow and spread around along the first side wall 21. Since the second plate 11 and the second side wall 22 are in contact with each other, and limited by the process and installation tolerance, the second plate 11 and the second side wall 22 cannot be closely attached, and there must be a certain gap. Then, these gaps will produce a siphon effect, enabling the water to further penetrate inward.

[0036] To further solve the above problems, in this embodiment, a water guide groove 112 is formed by partial depression at the position where the second plate 11 is in contact with the second side wall 22. The water guide groove 112 is in a U shape and has an opening with a certain width. The opening width of the water guide groove 112 is the range width from the front side to the rear side, and its rear side falls on the middle part of the second side wall 22, and the front side extends forward beyond the first side wall 21. There is a certain distance between the baffle 111 and the first side wall 21 to form a second flow channel 14. The straight direction of the second flow channel 14 faces the water guide groove 112, and in the front-rear direction, the second flow channel 14 falls within the width range of the water guide groove 112.

[0037] Water intruding onto the first side wall 21 will be siphoned by the second flow channel 14 to enter the second flow channel 14 from the left side, and flow downward along the front and rear side walls of the second flow channel 14. When the amount of water is large and causes water to overflow from the right side of the second flow channel 14, the water will be prevented from further contacting the second plate 11 due to the space enlarged by the water guide groove 112, thereby preventing the water from contacting and entering the gap between the second plate 11 and the second side wall 22. Similarly, due to the siphon effect of the second flow channel 14, water overflowing from the right side can also be maintained on the right side of the second flow channel 14 and will no longer spread further.

[0038] Furthermore, the first side wall 21 on the column 2 is bent toward the first plate 12 at the edge side away from the second side wall 22 to form a hook edge 23, and the hook edge 23 is formed by bending twice. A sealing strip is installed on the hook edge 23, and the sealing strip includes a slot 31 and an abutment 32. The end of the hook edge 23 is inserted into the slot 31, and the inner wall of the slot 31 is provided with a protrusion. When the end of the hook edge 23 is inserted into the slot 31, the protrusion will be deformed and tightly attached to the surface of the hook edge 23, thereby increasing the static friction between each other and ensuring that the sealing strip is fastened to the hook edge 23 and is not easy to fall off; the abutment 32 is arranged forward toward the first plate 12, and when the first plate 12 is closed, it will abut against the abutment 32, so that the abutment 32 is deformed and tightly attached to the first plate 12 to prevent water from passing through there and penetrating into other positions.

[0039] The waterproof structure described in the above embodiment is used as one of the components to form a box, cabinet and other equipment. Specifically, in one embodiment, a rectangular cabinet is provided, and the cabinet includes a top surface, a bottom surface, four peripheral side surfaces and four peripheral side edges. Figure 2 and Figure 3 , wherein the waterproof structure can be composed of one of the edges in the cabinet and the peripheral side surfaces on both sides of the edge, specifically, the first plate 12 and the second plate 11 are two peripheral side surfaces respectively, the right angle at the connection position of the first plate 12 and the second plate 11 is the edge, and the column 2 is a part of the supporting structure inside the cabinet.

[0040] Preferably, when the waterproof structure is set as a part of the above-mentioned cabinet, the second plate 11 can be a side sealing plate fixed on the cabinet, and the first plate 12 can be a switch door plate on the cabinet, and the switch door plate is in the form of a swing door, and one of the left and right sides thereof is provided with a hinge to connect with the cabinet.

[0041] Likewise, the waterproof structure can also be used for other edge positions on the cabinet.

[0042] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
