Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated substation technology, and more specifically to a prefabricated substation with drainage function. Background Technology
[0002] Prefabricated substations have replaced traditional civil engineering power distribution rooms and substations, becoming a new type of complete power distribution device. They are suitable for residential communities, urban public utilities, bustling city centers, construction power supplies, mines, factories, oil and gas fields, and wind power stations. Users can choose prefabricated substations according to different usage conditions and load levels.
[0003] When a prefabricated substation is used outdoors and encounters rain, rainwater will drip down the wind onto the side walls of the substation and flow down the side walls. When it flows through gaps such as door seams and ventilation holes, some rainwater will seep into the interior of the prefabricated substation, which can easily cause dampness inside the substation. This can lead to short circuits or burnout of electrical components, affecting the normal use of the prefabricated substation and posing a safety hazard. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safe and reliable box-type substation that can drain water in a timely manner.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a box-type substation with drainage function, comprising a box bottom and a box shell positioned above the box bottom. The upper surface of the box bottom is provided with a water collection trough concentric with the edge contour of the box bottom, and the lower surface of the box bottom is provided with a water flow trough coaxial with the water collection trough. The bottom of the water collection trough is provided with a plurality of drainage holes distributed along the contour of the water collection trough and communicating with the water flow trough. The side wall of the box bottom is provided with a plurality of side holes communicating with the water flow trough. Rainwater entering the box shell flows through the water collection trough, drainage holes, water flow trough and side holes in sequence and is discharged from the box shell.
[0006] As a further improvement of this utility model, multiple load-bearing plates are provided at the opening of the water collection tank.
[0007] As a further improvement of this utility model, the height of the upper surface of the plurality of load-bearing plates is less than the height of the upper surface of the bottom of the box.
[0008] As a further improvement of this utility model, the water channel is provided with a plurality of reinforcing plates distributed along the outline of the water channel.
[0009] As a further improvement of this utility model, the height of the lower surface of the plurality of reinforcing plates is greater than the height of the bottom surface of the box.
[0010] The beneficial effects of this utility model are as follows: Rainwater entering the casing flows sequentially through the water collection trough, drain holes, water channel, and side holes on the bottom of the casing before being discharged. Compared with existing technologies, this design effectively isolates rainwater around electrical components and allows rainwater to be discharged from the water collection trough in a timely manner, thereby preventing rainwater from directly contacting electrical components and causing short circuits, thus improving safety. At the same time, the timely discharge of rainwater from the water collection trough can reduce the humidity inside the casing, ensuring that electrical components operate normally in a suitable environment.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.
[0018] Reference Figures 1 to 5 As shown, a box-type substation with drainage function in this embodiment includes a box bottom 1 and a box shell 2 positioned above the box bottom 1;
[0019] Based on the aforementioned prior art, a water collection trough 3 is machined into the bottom 1 of the box on the upward surface. The water collection trough 3 is a rectangular ring and concentric with the bottom 1 of the box. A water flow trough 4 is machined into the bottom 1 of the box on the downward surface. The water flow trough 4 is also a rectangular ring and concentric with the bottom 1 of the box. The edge contour dimensions of the water collection trough 3 and the water flow trough 4 are similar. Multiple drainage holes 5 are machined along the contour of the water collection trough 3 on the bottom of the water collection trough 3 by drilling. The multiple drainage holes 5 are all vertically downward and connected to the water flow trough 4. Several side holes 6 are machined on the side wall of the bottom 1 of the box and connected to the inner cavity of the water flow trough 4. The relevant electrical components are all located on the part of the bottom 1 of the box surrounded by the water collection trough 3.
[0020] In rainy weather, rainwater enters the shell 2 through gaps such as door seams and ventilation holes and flows down the inner wall of the shell 2. The rainwater flows to the upper surface of the bottom 1 of the shell and then flows into the water collection trough 3. As the rainwater accumulates locally and spreads to the surroundings, the rainwater spreads to the drain hole 5 and flows into the water trough 4. The rainwater drips onto the ground at the opening of the water trough 4. If the ground has water absorption function, the rainwater is absorbed. If the ground is a smooth and closed tile or other non-water-absorbing material, the rainwater spreads to the surroundings until it spreads to the side hole 6. The rainwater flows through the side hole 6 and is discharged from the bottom 1 of the shell.
[0021] Compared to existing technologies, this design effectively isolates rainwater around electrical components and promptly drains it from the water collection tank 3, thus preventing rainwater from directly contacting electrical components and causing short circuits, thereby improving safety. At the same time, the timely drainage of rainwater from the water collection tank 3 reduces the humidity inside the housing 2, ensuring that electrical components operate normally in a suitable environment. The design with multiple drainage holes 5, compared to a single drainage hole 5, avoids the situation where water cannot be drained in time due to blockage of the drainage hole 5, ensuring the continuity and stability of the drainage function, while also improving drainage efficiency. Water can be discharged from the water collection tank 3 in time through the adjacent drainage holes 5, effectively slowing down the rate at which rainwater evaporates due to the high temperature inside the housing 2 during the flow process.
[0022] As one specific implementation method of the improvement, refer to Figure 2 and Figure 4 As shown, multiple pairs of grooves can be machined on the opposing walls of the water collection trough 3. The two ends of the load-bearing plate 7 are placed in the paired grooves so that the load-bearing plate 7 is snapped or inserted into the opening of the water collection trough 3. The part of the load-bearing plate 7 that is not snapped into the groove is suspended above the bottom of the water collection trough 3. Alternatively, the two ends of the load-bearing plate 7 can be welded to the opposing walls of the water collection trough 3. The installation method of the load-bearing plate 7 can be determined according to the actual design requirements. This design can improve the bending resistance of the side wall of the water collection trough 3 when subjected to external impact, effectively improve the structural stability of the water collection trough 3, and at the same time ensure the smooth flow of rainwater into the water collection trough 3.
[0023] As one specific implementation method of the improvement, refer to Figure 2 and Figure 4 As shown, the height of the upper surface of the multiple load-bearing plates 7 is less than the height of the upper surface of the bottom 1 of the box. After rainwater flows from the inner wall of the box shell 2 to the load-bearing plates 7, it accumulates on the load-bearing plates 7 and spreads to the surroundings. The spread of rainwater along the length of the load-bearing plates 7 is blocked by the opposing walls of the water collection troughs 3 and cannot continue to spread. The rainwater spreads along the width of the load-bearing plates 7 and drips into the water collection troughs 3. This design, compared with the design of making the upper surface of the load-bearing plates 7 flush with the upper surface of the bottom 1 of the box, can effectively prevent rainwater from flowing through the upper surface of the load-bearing plates 7 and reaching the center of the bottom 1 of the box, thus ensuring the normal use of electrical components.
[0024] As one specific implementation method of the improvement, refer to Figure 3 and Figure 5 As shown, multiple reinforcing plates 8 are provided inside the water tank 4, which are distributed along the outline of the water tank 4. The bottom of the water tank 4 and the two opposing walls are connected to the reinforcing plates 8. This design can compensate for the defect that the outer wall of the water tank 4 will be pushed outward and break due to the load of the bottom 1, and effectively improve the connection stability between the two opposing walls of the water tank 4.
[0025] To further explain, if the lower surface of the reinforcing plate 8 is flush with the lower surface of the bottom of the box 1, the number of side holes 6 is the same as the number of drainage holes 5 and they are set accordingly. If there is a height difference between the lower surface of the reinforcing plate 8 and the lower surface of the bottom of the box 1 and it is located in the water trough 4, the number of side holes 6 can be less than the number of drainage holes 5. Rainwater entering the water trough 4 through the drainage holes 5 will diffuse on the ground and flow through the gap directly below the reinforcing plate 8. The rainwater will eventually be discharged from the side holes 6. The latter is preferred in the above two cases. This reduces the number of side holes 6 that need to be processed in the bottom of the box 1, reduces the complexity of the process, and improves production efficiency. At the same time, the reduction in the number of side holes 6 can greatly slow down the decrease in the strength of the outer wall structure of the water trough 4, and indirectly ensure the stability of the bottom of the box 1 structure.
[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
