Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to an outdoor power distribution room with photovoltaic power generation function. Background Technology

[0002] Outdoor power distribution rooms refer to outdoor power distribution sites with low-voltage loads. They mainly distribute power to low-voltage users and are equipped with medium-voltage incoming lines, distribution transformers, and low-voltage distribution devices. They are used to install and protect various electrical equipment and realize the functions of power distribution, control, and protection.

[0003] Existing outdoor power distribution rooms are often at risk of flooding during use, especially in areas with heavy rainfall and during the rainy season. Municipal or rural drainage systems may be clogged with impurities, and the installation area of ​​the outdoor power distribution room may be lower than the overall terrain (the outdoor power distribution room cannot be too far from the power consumption site, and the power consumption site is located in a low-lying area, resulting in the outdoor power distribution room being in a low-lying environment). As a result, rainwater can easily accumulate and submerge the foundation of the outdoor power distribution room. If the IP protection level of the outdoor power distribution room is low or the seals are aging, rainwater can easily seep in from under the door of the outdoor power distribution room. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an outdoor power distribution room with photovoltaic power generation function to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outdoor power distribution room with photovoltaic power generation function, including a pre-embedded foundation, an above-ground foundation fixed on top of the pre-embedded foundation, a support base fixed on top of the above-ground foundation, and a base plate fixed on top of the support base; anti-fall railings are installed around the top of the base plate, and a notch is opened on one side of the anti-fall railing, a door is hinged in the notch, and a door pin is connected to one side of the door; an mounting plate is connected to one side of the base plate, and an anti-climbing rod is fixed to one side of the mounting plate.

[0006] By adopting the above technical solution, the main body of the distribution room is lifted by setting up the above-ground foundation, support base and bottom plate, avoiding the phenomenon of waterlogging at the bottom of the main body of the distribution room in the later stage when it is at a low-lying bottom end. Moreover, the interior of the support base is hollowed out, which plays a role in reducing weight and material consumption, avoiding a large increase in the overall weight and material consumption of the foundation due to raising the height of the main body of the distribution room. At the same time, the support base is relatively high, which can effectively reduce the possibility of surrounding personnel coming into contact with the main body of the distribution room, improving the safety of electricity use. Staff can climb up the bottom plate by erecting a ladder to enter the main body of the distribution room for maintenance work. When the staff walks on the bottom plate, the anti-fall fence reduces the risk of the staff falling. At the same time, the bottom of the anti-fall fence is hollowed out, facilitating the drainage of rainwater on the bottom plate, thus avoiding excessive water accumulation on the bottom plate and causing waterlogging in the main body of the distribution room. After the maintenance is completed, only need to close the door body, insert the door bolt, and finally hang the lock on the door bolt to prevent others from opening the door bolt. When someone wants to climb, due to the relatively high support base, the only climbing footholds are the bottom of the anti-fall fence and the edge of the bottom plate. When a person climbs and grabs these footholds, their palm or arm will very likely be in contact with the anti-climbing pole. Since the anti-climbing pole is conical, it will press painfully on the person's palm or arm. However, the shoulder of the anti-climbing pole is hemispherical, so it will only cause pain rather than stabbing, and stop people from climbing by causing pain, thus effectively reducing the phenomenon of people climbing to the top of the bottom plate.

[0007] Further, the cross-section of the support base is in the shape of a "field".

[0008] By adopting the above technical solution, the interior of the support base is hollowed out, which plays a role in reducing weight and material consumption, avoiding a large increase in the overall weight and material consumption of the foundation due to raising the height of the main body of the distribution room.

[0009] Further, a plurality of grooves are provided at the bottom of the anti-fall fence, and the plurality of grooves are equidistantly distributed in the shape of a "mouth".

[0010] By adopting the above technical solution, the bottom of the anti-fall fence is hollowed out, facilitating the drainage of rainwater on the bottom plate, thus avoiding excessive water accumulation on the bottom plate and causing waterlogging in the main body of the distribution room.

[0011] Further, the door body is rotatably connected to the anti-fall fence, and the door bolt is detachably connected to the anti-fall fence.

[0012] By adopting the above technical solution, after the maintenance is completed, only need to close the door body, insert the door bolt, and finally hang the lock on the door bolt to prevent others from opening the door bolt.

[0013] Further, a plurality of anti-climbing poles are provided, and the plurality of anti-climbing poles are all conical, and the tips of the plurality of anti-climbing poles are hemispherical.

[0014] By adopting the above technical solution, when someone wants to climb, because the support base is high, the only points of contact for climbing are the bottom of the fall arrest fence and the edge of the base plate. When a person climbs and grabs these points of contact, their palm or arm will most likely come into contact with the anti-climb pole. Since the anti-climb pole is conical, it will press and cause pain to the person's palm or arm. However, the shoulder of the anti-climb pole is hemispherical, so it will only cause pain rather than puncture. By causing pain, people are deterred from climbing, thus effectively reducing the occurrence of people climbing to the top of the base plate.

[0015] Furthermore, the height of the support base is 2m.

[0016] By adopting the above technical solution, the support base is relatively high, which can effectively reduce the possibility of people in the vicinity coming into contact with the main body of the power distribution room and improve electrical safety.

[0017] Furthermore, the main body of the power distribution room and a reinforced roof are installed on the top of the base plate, and photovoltaic panels are installed on the top of the reinforced roof. The main body of the power distribution room contains a power distribution room and a photovoltaic room.

[0018] By adopting the above technical solutions, the power distribution room is equipped with high-voltage / medium-voltage switchgear, transformers, low-voltage switchgear, heat dissipation systems, fire protection systems, cable trays, monitoring systems, etc., which can receive current from the municipal power grid and convert it into low-voltage current to power facilities such as residential communities and commercial shops. The photovoltaic room is equipped with static transfer switches, photovoltaic controllers, battery banks, inverters, DC distribution boxes, AC distribution boxes, battery management systems, monitoring systems, fire protection systems, cable trays, heat dissipation systems, etc., which can supply the current generated by the photovoltaic panels to the heat dissipation system, monitoring system and other power-consuming systems in the main body of the power distribution room, saving energy and protecting the environment. If the battery bank has low power, or if there is no sunlight to generate electricity in cloudy or rainy weather, the static transfer switch can be used to switch the circuit in the power distribution room to power the heat dissipation system, monitoring system and other power-consuming systems. In addition, the roof is reinforced to prevent the main body of the power distribution room from bearing the entire weight of the photovoltaic panels, and to prevent the roof of the power distribution room from collapsing after rain and snow.

[0019] Furthermore, the fall protection fence, mounting plate, anti-climb pole, gate body and door pin are all made of galvanized steel, 304 stainless steel or 316 stainless steel with anti-corrosion paint sprayed on the surface.

[0020] By adopting the above technical solutions, galvanized steel coated with anti-corrosion paint can achieve a more aesthetically pleasing effect through different colors of anti-corrosion paint, and the cost is low. However, the corrosion resistance is relatively long, and rust is still likely to occur after long-term use. 304 stainless steel has better corrosion resistance and can be used for a long time, but the cost is higher than that of galvanized steel. Although it can also be painted to change the color to increase the aesthetics, the cost will increase further. 316 stainless steel has the best corrosion resistance and can withstand long-term outdoor corrosion, but the cost is the highest.

[0021] Furthermore, the embedded foundation, the above-ground foundation, and the support base are all made of C40 concrete and epoxy resin coated HRB400E steel bars, and the bottom plate is made of C50 concrete and epoxy resin coated HRB500E steel bars.

[0022] By adopting the above technical solutions, C40 steel bars are widely used in beams, slabs, columns, and general foundations of buildings, exhibiting good durability, strength, and economy. C50 concrete has higher strength and durability than C40, effectively supporting the main body of the power distribution room and the equipment within it. HRB400E and HRB500E steel bars have high strength and good ductility, meeting seismic requirements. Furthermore, the surface of the steel bars is coated with epoxy resin to prevent chloride ion, sulfate, and electrochemical corrosion, extending the service life of the steel bars, while also having a relatively low cost.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model elevates the main body of the power distribution room by setting up a pre-embedded foundation, an above-ground foundation, a support base, and a base plate. This prevents the main body of the power distribution room from being located at a low-lying bottom, which could easily lead to water ingress later. Furthermore, the hollow interior of the support base reduces weight and material consumption, avoiding a significant increase in the overall weight and material consumption of the foundation due to the increased height of the main body of the power distribution room. At the same time, the higher height of the support base effectively reduces the possibility of people coming into contact with the main body of the power distribution room, improving electrical safety; it also increases the waterproofing effect and reduces the possibility of contact by non-professionals.

[0025] 2. This utility model, through the installation of a fall arrestor fence, a door, and a door latch, allows workers to climb a ladder onto the base plate to enter the main body of the power distribution room for maintenance work. When workers walk on the base plate, the fall arrestor fence reduces the risk of falls. Simultaneously, the bottom of the fall arrestor fence is perforated to facilitate the drainage of rainwater from the base plate, thus preventing excessive water accumulation and flooding of the main body of the power distribution room. After maintenance is completed, simply close the door, insert the door latch, and finally attach the lock to the door latch to prevent unauthorized access. This improves safety during maintenance, increases drainage capacity, and further prevents access by non-professionals.

[0026] 3. This utility model uses an installation plate and an anti-climb rod. The installation plate is fastened to the edge of the base plate with bolts to complete the installation of the anti-climb rod. When a person tries to climb, because the support base is high, the only points of force for climbing are the bottom of the fall protection fence and the edge of the base plate. When a person climbs and grabs these points of force, their palm or arm is very likely to come into contact with the anti-climb rod. Since the anti-climb rod is conical, it will press painfully on the person's palm or arm. However, the shoulder of the anti-climb rod is hemispherical, so it will only cause pain rather than puncture. By causing pain, it discourages people from climbing, thereby effectively reducing the occurrence of people climbing to the top of the base plate; effectively reducing the occurrence of climbing.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] An outdoor power distribution room with photovoltaic power generation function, such as Figures 1-5As shown in the figure, it includes a pre-buried foundation 1. A ground foundation 2 is fixed on the top of the pre-buried foundation 1. A support base 3 is fixed on the top of the ground foundation 2. The height of the support base 3 is 2m. The cross-section of the support base 3 is in the shape of a Chinese character '田' (field). A bottom plate 4 is fixed on the top of the support base 3; Anti-fall fences 10 are installed around the top of the bottom plate 4. Multiple grooves are provided at the bottom of the anti-fall fences 10. The multiple grooves are equidistantly distributed in the shape of a Chinese character '口' (square). A notch is provided on one side of the anti-fall fence 10. A door body 13 is hinged in the notch. The door body 13 is rotatably connected to the anti-fall fence 10. A door bolt 14 is connected to one side of the door body 13. The door bolt 14 is detachably connected to the anti-fall fence 10; An installation plate 11 is connected to one side of the bottom plate 4. An anti-climbing rod 12 is fixed on one side of the installation plate 11. There are multiple anti-climbing rods 12. The multiple anti-climbing rods 12 are all conical. The tips of the multiple anti-climbing rods 12 are hemispherical. By setting the ground foundation 2, the support base 3 and the bottom plate 4, the main body 5 of the distribution room is raised, avoiding the phenomenon that water is likely to accumulate at the bottom of the main body 5 of the distribution room in the later stage when it is at a low-lying bottom. Moreover, the interior of the support base 3 is hollow, which plays a role in reducing weight and material consumption, avoiding a large increase in the overall weight and material consumption of the foundation due to increasing the height of the main body 5 of the distribution room; At the same time, the height of the support base 3 is relatively high, which can effectively reduce the possibility of surrounding personnel contacting the main body 5 of the distribution room and improve the safety of electricity use. The staff can climb onto the bottom plate 4 through a ladder to enter the main body 5 of the distribution room for maintenance work. When the staff walks on the bottom plate 4, the anti-fall fence 10 reduces the risk of the staff falling. At the same time, the bottom of the anti-fall fence 10 is hollowed out, facilitating the drainage of rainwater on the bottom plate 4, thus avoiding excessive water accumulation on the bottom plate 4 and causing water to enter the main body 5 of the distribution room; After the maintenance is completed, just close the door body 13 and insert the door bolt 14, and finally hang the lock on the door bolt 14 to prevent others from opening the door bolt 14. And the installation plate 11 is fastened to the edge of the bottom plate 4 by bolts to complete the installation of the anti-climbing rod 12. When someone wants to climb, due to the relatively high support base 3, the only climbing着力点 are the bottom of the anti-fall fence 10 and the edge of the bottom plate 4. When the person climbs and grabs these着力点, their palm or arm will most likely be in contact with the anti-climbing rod 12. Since the anti-climbing rod 12 is conical, it will press painfully against the person's palm or arm. However, the shoulder of the anti-climbing rod 12 is hemispherical, so it will only cause pain rather than stabbing, stopping people from climbing by causing pain, thus effectively reducing the occurrence of the phenomenon that people climb to the top of the bottom plate 4.

[0037] Refer to Figure 1 and Figure 2 It should be noted that the text seems to have some unclear or inaccurate expressions in the original Chinese, especially the part about "着力点" which is not clearly defined. The translation tries to make sense of the overall context as accurately as possible.In the above embodiment, the main body of the power distribution room 5 and the reinforced roof 6 are installed on the top of the base plate 4. Photovoltaic panels 7 are installed on the top of the reinforced roof 6. The main body of the power distribution room 5 is equipped with a power distribution room 8 and a photovoltaic room 9. The power distribution room 8 is equipped with high-voltage / medium-voltage switchgear, transformers, low-voltage switchgear, heat dissipation systems, fire protection systems, cable trays, monitoring systems, etc., and can receive current from the municipal power grid and convert it into low-voltage current to power residential areas, commercial shops and other facilities. The photovoltaic room 9 is equipped with a static transfer switch, photovoltaic controller, battery pack, inverter, DC distribution box, etc. The AC distribution box, battery management system, monitoring system, fire protection system, cable tray, heat dissipation system, etc., can supply the current generated by the photovoltaic panel 7 to the heat dissipation system, monitoring system and other power-consuming systems in the main body of the power distribution room 5, saving energy and protecting the environment. If the battery pack has low power, or if there is no sunlight to generate electricity in cloudy or rainy weather, the circuit in the power distribution room 8 can be changed to supply power to the heat dissipation system, monitoring system and other power-consuming systems through a static transfer switch. In addition, the roof 6 is reinforced to prevent the main body of the power distribution room 5 from bearing the entire weight of the photovoltaic panel 7, and to prevent the roof of the main body of the power distribution room 5 from collapsing after rain and snow.

[0038] Example 2:

[0039] Based on the above embodiment one, in order to extend the service life of the protective structure, the following settings are now implemented.

[0040] See Figure 1 , Figure 3 and Figure 4 In the above embodiments, the fall arrest fence 10, mounting plate 11, anti-climb pole 12, gate body 13, and door pin 14 are all made of galvanized steel, 304 stainless steel, or 316 stainless steel with anti-corrosion paint sprayed on the surface. Galvanized steel with anti-corrosion paint spraying can achieve a more aesthetically pleasing effect through different colors of anti-corrosion paint, and the cost is low, but the corrosion resistance is relatively long, and it is still prone to rust after long-term use. 304 stainless steel has better corrosion resistance and can be used for a long time, but the cost is higher than that of galvanized steel. Although the aesthetics can be improved by spraying paint, the cost will increase further. 316 stainless steel has the best corrosion resistance and can withstand long-term outdoor corrosion, but the cost is the highest.

[0041] Example 3:

[0042] Based on the above embodiment one, in order to increase the structural strength of the foundation system, the following settings are now adopted.

[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 5In the above embodiments, the embedded foundation 1, the above-ground foundation 2 and the support base 3 are all made of C40 concrete and epoxy resin coated HRB400E steel bars, and the base plate 4 is made of C50 concrete and epoxy resin coated HRB500E steel bars. The structure has high strength and seismic resistance, which can effectively prevent the collapse of the raised foundation and ensure long-term use.

[0044] The implementation principle of this utility model is as follows: First, the embedded base, the ground foundation 2, the support plate and the bottom plate 4 are made of C40 or C50 concrete and epoxy resin coated HRB400E steel bars or epoxy resin coated HRB500E steel bars. The specific processing can be carried out by on-site segmented casting or by prefabrication and assembly on-site. If the environment has high requirements for corrosion resistance and waterproofing, materials with higher grades or other materials can be selected, such as stainless steel steel bars. Casting and prefabrication are existing technologies, and this technical solution will not be described in detail here. The main body of the power distribution room 5 is installed by hoisting, that is, the main body of the power distribution room 5 is hoisted to the top of the bottom plate 4 by using lifting equipment for installation. Hoisting is the most commonly used installation method in this field, so this solution will not be described in detail here either.

[0045] The power distribution room 8 is equipped with high-voltage / medium-voltage switchgear, transformers, low-voltage switchgear, a cooling system, a fire protection system, cable trays, and a monitoring system. It can receive current from the municipal power grid and convert it into low-voltage current to power residential areas, commercial shops, and other facilities. The photovoltaic room 9 is equipped with a static transfer switch, photovoltaic controller, battery bank, inverter, DC distribution box, AC distribution box, battery management system, monitoring system, fire protection system, cable trays, and a cooling system. It can supply the current generated by the photovoltaic panels 7 to the cooling system, monitoring system, and other power-consuming systems in the main body of the power distribution room 5, saving energy and protecting the environment. If the battery bank has low power or there is no sunlight to generate electricity during cloudy or rainy weather, the static transfer switch can be used to switch the circuit in the power distribution room 8 to power the cooling system, monitoring system, and other power-consuming systems. In addition, the reinforced roof 6 prevents the main body of the power distribution room 5 from bearing the entire weight of the photovoltaic panels 7, thus preventing the roof of the main body of the power distribution room 5 from collapsing after rain and snow.

[0046] By constructing a foundation 2, support base 3, and base plate 4, the main body of the power distribution room 5 is raised, preventing water from easily seeping into the bottom of the room due to its low-lying location. The hollow interior of the support base 3 reduces weight and material consumption, avoiding a significant increase in overall foundation weight and material costs associated with raising the main body of the power distribution room 5. Simultaneously, the higher support base 3 effectively reduces the possibility of personnel coming into contact with the main body of the power distribution room 5, improving electrical safety. Workers can climb the base plate 4 using ladders to access the main body of the power distribution room 5 for maintenance work. When workers walk on the base plate 4, the fall arrestor 10 reduces the risk of falls, and the hollow bottom of the fall arrestor 10 facilitates the drainage of rainwater from the base plate 4, thus preventing... Excessive water accumulation on the base plate 4 can cause water to flood the main body 5 of the power distribution room. After maintenance and repair, simply close the door 13, insert the door latch 14, and finally hang the lock on the door latch 14 to prevent others from opening it. When someone tries to climb, because the support base 3 is high, the only points of leverage for climbing are the bottom of the fall arrest fence 10 and the edge of the base plate 4. When a person climbs and grabs these points of leverage, their palm or arm is very likely to come into contact with the anti-climb pole 12. Since the anti-climb pole 12 is conical, it will press on the person's palm or arm, causing pain. However, the shoulder of the anti-climb pole 12 is hemispherical, so it will only cause pain rather than puncture. By causing pain, people are deterred from climbing, thus effectively reducing the occurrence of people climbing to the top of the base plate 4.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
