Description

Technical Field

[0001] This utility model relates to the technical field of energy storage cabinets, specifically to a cabinet structure for an energy storage electrical appliance. Background Technology

[0002] Currently, energy storage cabinets typically consist of a cabinet body, a top cover, and a door. They are waterproofed through a combination of sealing strips, door frame drainage channels, and a top cover. However, this design has the following problems: during rain, in post-rain weather, or in humid conditions, water accumulates on the underside of the top cover and the top of the door frame. When the door is opened for inspection, the water, due to the inertia of opening the door, rolls down the door and onto the inner side of the door panel. The inner side of the door panel often houses various electrical components and cables, posing a significant safety risk, such as short circuits. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an energy storage electrical cabinet structure.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] An energy storage electrical cabinet enclosure structure includes:

[0006] The cabinet includes a first side wall with an opening. A door frame protrudes from the edge of the opening towards the outside of the cabinet. A sealing part is provided on the circumferential edge of the door frame so that the first side wall, the door frame and the sealing part form a door frame drainage groove.

[0007] A cabinet door is rotatably mounted on the cabinet body for opening or closing the opening, so that the cabinet door has an open state and a closed state; a first shielding edge is provided on the periphery of the cabinet door, which is used to cover the door frame drainage groove; when the cabinet door is in the closed state, the side wall of the cabinet door is attached to the sealing part; the upper end surface of the first shielding edge is provided with a first inclined part for draining water droplets;

[0008] The top cover is installed on the upper part of the cabinet. The top cover includes mutually perpendicular length and width directions. The lower end face of the top cover is provided with a first drainage channel, which is located above the door frame drainage channel. The first drainage channel includes a first channel wall, a second channel wall, and a channel bottom to form a channel structure with a U-shaped cross-section. The channel bottom is provided with evaporation holes at intervals along the length direction, and there is a gap between the two ends of the evaporation holes and the first channel wall and the second channel wall, respectively, along the width direction. The channel bottom is provided with a second inclined part corresponding to the cabinet door. The second inclined part is inclined along the length direction and inclined downwards towards the outside of the cabinet along the width direction, so that a drainage area is formed between the channel bottom and the first channel wall. A first drainage hole is opened at the inclined lower end of the drainage area along its length direction.

[0009] Optionally, the upper surface of the first shielding edge has two first inclined portions, and the two first inclined portions form an inverted V-shaped structure.

[0010] Optionally, two second inclined portions are provided for each cabinet door, and the two second inclined portions form an inverted V-shaped structure.

[0011] Optionally, there are two openings, and correspondingly two cabinet doors.

[0012] Optionally, the top of the cabinet is provided with an installation frame, the periphery of the installation frame is provided with stepped grooves, the top cover is fixedly installed on the installation frame to cover and seal the installation frame, and the periphery of the top cover is engaged with the stepped grooves to form a waterproof labyrinth structure.

[0013] Optionally, the top cover includes two inclined panels, which are inclined downward along the length direction and form an inverted V-shaped structure; the top cover is provided with a second drainage channel at the lower inclined end of each of the two inclined panels, the second drainage channel is used to receive water flowing down from the inner wall of the inclined panel; a second drain hole is provided on the second drainage channel.

With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-10 This embodiment provides an energy storage electrical cabinet structure, including a cabinet body 1, a cabinet door 2, and a top cover 3.

[0031] The cabinet 1 includes a first side wall 11 with an opening 12. A door frame 13 is provided on the circumferential edge of the opening 12 of the first side wall 11 protruding outward from the cabinet 1. A sealing part 14 is provided on the circumferential edge of the door frame 13 so that the first side wall 11, the door frame 13 and the sealing part 14 form a door frame drainage groove 15.

[0032] The cabinet door 2 is rotatably mounted on the cabinet body 1 to open or close the opening 12, so that the cabinet door 2 has an open state and a closed state. A first blocking edge 21 is provided on the periphery of the cabinet door 2 to cover the door frame drainage groove 15. The upper end surface of the first blocking edge 21 is provided with a first inclined part 22 for draining water droplets.

[0033] The top cover 3 is installed on the upper part of the cabinet 1. The top cover 3 includes mutually perpendicular length direction X and width direction Y. The lower end surface of the top cover 3 is provided with a first drainage channel 31, which is a channel structure formed by folding the edge of the top cover 3 inward. Specifically, the first drainage channel 31 is located above the door frame drainage channel 15. The first drainage channel 31 includes a first channel wall 311, a second channel wall 312, and a channel bottom 313 to form a channel structure with a U-shaped cross-section. The first channel wall 311 is the channel wall away from the center of the top cover 3, and the second channel wall 312 is the channel wall closer to the center of the top cover 3. The channel bottom 313 is provided with evaporation holes 314 at intervals along the length direction, and there are gaps between the two ends of the evaporation holes 314 and the first channel wall 311 and the second channel wall 312 respectively along the width direction of the top cover 3. The bottom of the groove 313 is provided with a second inclined part 315 corresponding to the cabinet door 2. The second inclined part 315 is inclined along the length direction and inclined downwards at an angle P along the width direction towards the outside of the cabinet 1, such as... Figure 7 As shown, a drainage area 316 is formed at the junction between the bottom of the tank 313 and the first tank wall 311. A first drainage hole 317 is provided at the inclined lower end of the drainage area 316 along its length, as shown... Figure 8 and Figure 9 As shown.

[0034] With the door frame 13 and the sealing part 14, most of the accumulated water can be automatically discharged from both sides of the upper end of the door frame drainage groove 15. With the first inclined part 22, in rainy or humid weather, water droplets can be discharged along the first inclined part 22, thereby reducing water accumulation on the upper surface of the first shielding edge 21 of the cabinet door 2. With the second inclined part 315, water vapor can enter the first drainage groove 31 through the evaporation hole 314 after evaporation, and after condensation, form water droplets that flow out from the first drainage hole 317 at the lower end of the drainage area 316, thereby reducing the accumulation of water vapor on the lower surface of the edge of the top cover 3 after condensation. Furthermore, there is a gap between the two ends of the evaporation hole 314 and the first groove wall 311 and the second groove wall 312 along the width direction, so that the evaporation hole 314 does not interfere with the drainage area 316, preventing water droplets from flowing directly out of the evaporation hole 314 and dripping again onto the middle position of the upper surface of the first shielding edge 21, such as... Figure 4 As shown.

[0035] This reduces water accumulation on the top cover 3 and the upper surface of the cabinet door 2. When the cabinet door 2 is opened for maintenance, it reduces the likelihood of water droplets falling onto the electrical components inside the cabinet door 2 due to inertia, thus reducing safety hazards. Furthermore, regarding dust on the top of the cabinet door 2, the accumulated dust, positioned at an angle, is washed away by gravity and rainwater over time, reducing dust accumulation on the top of the cabinet door 2 and preventing dust from entering the electrical components inside the cabinet and affecting their creepage distance.

[0036] Furthermore, two first inclined portions 22 are provided on the upper surface of the first shielding edge 21, and the two first inclined portions 22 form an inverted V-shaped structure. In this way, water droplets can be guided and discharged to both sides by the two first inclined portions 22. In other embodiments, only one first inclined portion 22 can be provided, that is, it is inclined from one end of the upper surface of the first shielding edge 21 to the other end. In comparison, when having the same inclination angle, providing one first inclined portion 22 requires a longer inclination length; providing two first inclined portions 22 with opposite inclination directions can make reasonable use of the length of the cabinet door 2 and ensure that there is a sufficient inclination angle so that water droplets can be smoothly guided.

[0037] Similarly, two second inclined portions 315 are provided for each cabinet door 2, and the two second inclined portions 315 form an inverted V-shaped structure. The upper surface of the first drainage channel 31 of the top cover 3 and the upper surface of the first shielding edge 21 of the cabinet door 2 are designed with double parallel lines, which not only meets the drainage requirements, but also does not increase the gap between the cabinet door 2 and the top cover 3, and has no impact on the overall appearance of the energy storage cabinet structure. The gap between the cabinet door 2 and the top cover 3, when viewed up close, resembles a long wave, which also enhances the overall aesthetics; when viewed from a distance, it is almost a straight line parallel to the horizontal plane.

[0038] Furthermore, there are two openings 12, and two cabinet doors 2 are correspondingly provided. In this embodiment, the two openings 12 are of different sizes, the door frame drainage groove 15 has the same structure, and correspondingly, the two cabinet doors 2 are of different sizes, forming a double-door structure with one large and one small opening.

[0039] Furthermore, a mounting frame 4 is provided on the top of the cabinet 1. The mounting frame 4 has stepped grooves 41 on three sides, forming a "U"-shaped structure. The top cover 3 is fixedly mounted on the mounting frame 4 to cover and seal the mounting frame 4, and the peripheral edge of the top cover 3 is engaged with the stepped grooves 41 to form a waterproof labyrinth structure. In this way, water droplets left from the edge of the top cover 3 fall onto the stepped grooves 41 and flow out from the outside of the side wall of the cabinet 1.

[0040] Furthermore, the top cover 3 includes two inclined panels 32, which are inclined downwards along their length and have an inverted V-shaped structure. Each of the two inclined panels 32 has a second drainage groove 33 at its lower inclined end. The second drainage groove 33 is used to collect water flowing down from the inner wall of the inclined panel 32; a second drain hole 331 is provided on the second drainage groove 33. In humid weather or areas with high humidity, water vapor will condense on the inner wall of the inclined panel 32. Through the arrangement of the inclined panel 32, water droplets on its inner wall can flow to the second drainage groove 33 and then be discharged from the second drain hole 331 of the second drainage groove 33 to the stepped groove 41.

[0041] Furthermore, a third drainage channel 34 is provided on the side of the top cover 3 away from the first drainage channel 31, and a third drainage hole 341 is provided at intervals along the length of the top cover 3 at the bottom of the third drainage channel 34. As a preventive design, the third drainage channel 34 and the third drainage hole 341 may allow a small amount of water droplets to drain from the third drainage hole 341 into the stepped groove 41.

[0042] Furthermore, the sealing part 14 includes a rubber sealing strip 141. When the cabinet door 2 is closed, the rubber sealing strip 141 can press against the inner wall of the cabinet door 2, thereby preventing water from flowing into the inside of the cabinet door 2.

[0043] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
