Description

Technical Field

[0001] This utility model belongs to the field of switchgear and relates to a novel waterproof top cover. Background Technology

[0002] High-voltage switchgear needs to operate indoors in substations or prefabricated warehouses, and has high environmental requirements. The cabinets are generally equipped with temperature and humidity controllers and heaters. Substations or prefabricated warehouses are also usually equipped with air conditioning and other equipment to control temperature and humidity to prevent accidents such as short circuits caused by condensation. However, in some areas with high humidity, indoor temperature and humidity cannot be well controlled to an ideal state, and dripping water from the top is difficult to avoid. Existing high-voltage switchgear's conventional top cover is limited by its structure and inevitably has gaps, such as the splicing seams between pressure relief covers. Therefore, there is a risk of water dripping into the cabinet, leading to accidents such as short circuits. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a new type of waterproof top cover.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel waterproof top cover includes a first water guide channel and a second water guide channel disposed on the top of a conventional top cover. At least one end of the first water guide channel forms a first outlet, and at least one end of the second water guide channel forms a second outlet. The first water guide channel and the second water guide channel are spliced ​​and connected at a set angle, and the first outlet communicates with the second water guide channel.

[0006] Furthermore, the first water guide channel includes a first base plate and first bent side plates disposed on opposite sides of the first base plate, and the first outlet is disposed at the end of the first bent side plate.

[0007] Furthermore, the second water guide channel includes a second bottom plate and second bent side plates disposed on opposite sides of the second bottom plate, and the second outlet is disposed at the end of the second bent side plate.

[0008] Furthermore, the first outlet is connected to the second bent side plate, and the first outlet is provided with a bent portion located at the end of the first bottom plate and the end of the first bent side plate, the bent portion abutting against the inner side wall of the second bent side plate respectively.

[0009] Furthermore, there are two first outlets located at opposite ends of the first water guide channel, and two second water guide channels located on both sides of the first water guide channel.

[0010] Furthermore, the first water guide channel and the second water guide channel are perpendicular to each other.

[0011] Furthermore, one of the second bending side plates of the second water guide channel has a water-blocking bending part on its top, which is bent laterally. When two adjacent second water guide channels are spliced ​​together, the water-blocking bending part is located above the two adjacent second bending side plates.

[0012] Furthermore, it also includes a third water guide channel, which is disposed on the adjacent side of the first water guide channel. The third water guide channel includes a third outlet and a baffle plate. The baffle plate abuts against the adjacent first bent side plate, and the top of the baffle plate is bent laterally.

[0013] In summary, the advantages of this utility model are as follows:

[0014] This utility model provides a modular waterproof top cover for conventional switchgear. The first water guide channel forms a barrier to seal the top gap, and the second water guide channel forms a backflow of condensate, thereby effectively preventing condensate from entering the cabinet. The waterproof top cover is modular and assembled with screws, which makes it easy to install and operate, highly applicable, and cost-effective. Attached Figure Description

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0023] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0024] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0025] This embodiment provides a novel waterproof top cover, including a first water guide channel and a second water guide channel. The waterproof top cover is installed on the conventional top cover 1 on the top of the cabinet to form a condensate drainage channel on the top of the cabinet.

[0026] Reference Figure 2 The cabinet's conventional top cover 1 includes multiple pressure relief covers 11, with joints 12 formed between adjacent pressure relief covers 11. When condensation occurs inside the substation or prefabrication chamber, water droplets may enter the cabinet through the joints 12, potentially causing short circuits or other accidents. (Refer to...) Figure 1 and Figure 3The first water guide channel is disposed between adjacent pressure relief covers 11. The first water guide channel includes a first base plate 21 and a first bent side plate 22. The first base plate 21 is laid at the bottom between two adjacent pressure relief covers 11, providing sufficient cover to the bottom of the splice seam 12. The first bent side plate 22 includes two plates, which are respectively disposed on both sides of the first base plate 21, forming an upward bend. The first bent side plates 22 on both sides abut against the sides of the pressure relief covers 11 on both sides. When water droplets fall, condensate falls onto the first base plate 21. The first water guide channel forms a first outlet 23 at the end perpendicular to the line connecting the two first bent side plates 22. The condensate flows to the first outlet 23 under the constraint and guidance of the first base plate 21 and the first bent side plate 22.

[0027] The second water guide channel is located on the side of the conventional top cover 1 of the cabinet and forms a set angle with the first water guide channel, preferably perpendicular to it. The second water guide channel includes a second base plate 31 and a second bent side plate 32. The second bent side plate 32 includes two plates and is respectively located on both sides of the second base plate 31, forming an upward bend. The first outlet 23 of the first water guide channel is connected to the corresponding second bent side plate 32 on the second water guide channel. Condensate flows from the first base plate 21 into the second base plate 31 through the first outlet 23, and preferably the height of the second base plate 31 is lower than the height of the first base plate 21.

[0028] The second water guide channel has a second outlet at one or both ends along its length. The condensate on the second water guide channel flows to the second outlet and is discharged to the outside of the cabinet under the restriction and guidance of the second base plate 31 and the second bent side plate 32.

[0029] Both the first and second water guide channels are fixedly connected to the conventional top cover 1 of the cabinet by bolts. The first outlet 23 of the first water guide channel is provided with a bending part, which is respectively located at the end of the first bottom plate 21 and the end of the first bending side plate 22. The bending part bends towards the second bending side plate 32 and abuts against the inner side wall of the second bending side plate 32, so that the first water guide channel and the second water guide channel are more tightly connected and the gap at the connection is covered to prevent condensate from leaking during the flow from the first water guide channel to the second water guide channel.

[0030] Preferably, the first water guide channel has a first outlet 23 on each side, and the second water guide channel has two outlets located on both sides of the conventional top cover 1 of the cabinet. One of the two second water guide channels has a horizontally outwardly bent water-blocking bend 33 on the top of the outermost second bent side plate 32. (Refer to...) Figure 4When two cabinets are joined together, the second water guide channels on the two cabinets become adjacent, and the second bent side plates 32 on both sides become adjacent and abut each other. The water-blocking bend 33 on one of the second bent side plates 32 is located above the gap formed between the two second bent side plates 32, guiding the condensate into the second water guide channel on either side, and preventing the condensate from flowing into the gap.

[0031] Furthermore, it also includes a third water guide channel 4, as shown in the reference. Figure 1 and Figure 5 The third water guide trough 4 is located on one side of the first water guide trough and is adjacent to the first bent side plate 22. The opposite sides of the third water guide trough 4 are provided with upward-facing third bent side plates. The opposite ends perpendicular to the line connecting the two third bent side plates are respectively provided with a third outlet and a baffle plate 41. The condensate falling on the third water guide trough 4 is discharged out of the cabinet through the third outlet. The baffle plate 41 is set upward on the third water guide trough 4. The baffle plate 41 abuts against one of the first bent side plates 22 of the adjacent first water guide trough. The top of the baffle plate 41 is bent laterally towards the first water guide trough, thereby blocking the top of the gap between the baffle plate 41 and the first bent side plate 22.

[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
