Description

Technical Field

[0001] The invention belongs to the technical field of substation flood control design and construction, and particularly relates to a substation area flood control structure. Background Art

[0002] Substations with voltage levels of 35 kV and above are a crucial component of power grid construction, fulfilling crucial tasks such as voltage change, power distribution, and protection and control. Current substation design often follows conventional civilian design, encompassing power facilities, buildings, cable trenches, and walls. Waterproofing and flood control primarily rely on walls, sandbags, and pumps. While this design generally ensures adequate protection for power facilities during normal rainfall, its inadequacy can be easily exposed during more severe storms. Some new substations, to mitigate flooding and waterproofing, are considered to be located on elevated terrain, effectively preventing flooding during extreme weather conditions. However, for most existing substations, if they were not originally constructed on elevated terrain, their flood resistance is significantly weakened, posing a serious safety hazard. In the event of a flood, this can severely damage power facilities.

[0003] Therefore, it is urgent to develop a new substation area flood control structure, which can be used for flood control design and construction of new stations, as well as for flood control renovation of existing substation areas, to effectively improve the waterproof and flood resistance capabilities of substations as power grid hubs and maximize the safety of the power grid. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A substation flood control structure comprises a substation enclosure wall arranged outside the substation enclosure, at least one circle of outer protective wall, multiple circles of moats and one circle of slope protection arranged in sequence outside the substation enclosure wall, a plurality of retractable ditch covers provided on the top of each circle of moats, and at least one independent drainage device provided in each circle of moats, the drainage device being used to divert accumulated water in the moat to a drainage system outside the substation enclosure or directly to the ground outside the slope protection.

[0006] Preferably, the station area wall adopts a circular ring structure to increase the wall's ability to withstand external flood pressure.

[0007] Preferably, two circles of guard walls are provided outside the station area wall, and each circle of the guard walls is an independent wall. The station area wall and the two circles of guard walls are superimposed on each other, which can greatly enhance the flood resistance of the station area wall.

[0008] Preferably, the moat is provided with 3 to 5 circles to achieve multi-circle interception and water storage.

[0009] Preferably, the depth of each circle of the moat is 3 to 5 meters, with a certain water storage and interception capacity, and the width is greater than 1 meter, which facilitates personnel to regularly enter the moat to inspect and maintain the drainage system, and also facilitates regular cleaning of debris at the bottom of the moat. A trench cover is provided above the moat, and the trench cover is clamped on the trench cover. The trench cover can be opened in heavy rain to achieve water storage and interception.

[0010] Preferably, the slope protection is in the shape of an arch bridge, which is convenient for vehicles or pedestrians to pass through.

[0011] Preferably, the height of the slope protection is ≥500 mm, so as to intercept flood water as much as possible on the periphery of the slope protection.

[0012] Preferably, the drainage device includes a drainage pump and a sewage pipe. The drainage pump is arranged at the bottom of the moat. The water inlet end of the sewage pipe is connected to the water outlet of the drainage pump. The water outlet end of the sewage pipe of each set of the drainage device is connected to the outside of the slope protection through a drainage main pipe, and the water outlet end of the sewage pipe and the water outlet end of the drainage main pipe are both provided with a one-way valve, which can effectively block rainwater from approaching the substation area and prevent rainwater from flowing back into the moat along the sewage pipe and the drainage main pipe.

[0013] The present invention also includes other devices or components that can enable the substation flood control structure to be used normally, all of which are conventional technical means in this field; in addition, the devices and components not limited in the present invention all adopt conventional technical means in this field, such as trench covers, drainage systems outside the station area, drainage pumps, sewage pipes, sewage main pipes, etc.

[0014] The invention works by creating a protective slope, a protrusion from the flat ground, that acts as a wall, effectively forming the first barrier between the substation and the surrounding ground, separating the substation from the outside world. Multiple moats are located between the outer protective wall and the protective slope, each equipped with an independent drainage system. In normal weather, the moats are covered by trench covers, preventing traffic from interrupting movement. In rainy weather, the trench covers can be opened, serving as trenches to prevent flooding. Each outer moat buys time for the inner moat, and the independent drainage systems within each moat delay and effectively block rainwater from reaching the substation. The station wall, serving as the final line of defense, adopts a circular structure to increase its resistance to external flooding. Furthermore, at least one outer protective wall surrounds the outer perimeter of the substation wall, each forming an independent wall. Together, these walls significantly enhance the flood control capabilities of the station wall.

[0015] Compared with the existing technology, the present invention has the following beneficial effects: the present invention can be used for the flood control design and construction of newly built station areas, and can also be used for the flood control renovation of existing substation areas. It can form a strong protective net and realize three-in-one safety protection. When flooding occurs, it can add a layer of safety protection to the station area, effectively improve the waterproof and flood resistance ability of the substation as a power grid hub, and maximize the safety of the power grid.

[0020] The present invention is described below in conjunction with the accompanying drawings and specific embodiments of the present invention. The description herein is only used to explain the present invention and is not intended to limit the present invention. Based on the embodiments of the present invention, any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without creative work based on all other embodiments obtained in the present invention should be included in the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1 to 3 As shown, the present invention provides a substation area flood control structure, including a station area wall 2 arranged outside the substation area 1, and two circles of arch guard outer walls 3, four circles of moat 4 and one circle of slope protection 5 are sequentially arranged outside the station area wall 2, the top of each circle of the moat 4 is provided with a plurality of openable and closable groove covers, and two sets of independent drainage devices are symmetrically provided along the substation area 1 in each circle of the moat 4, the drainage device includes a drainage pump 6 and a sewage pipe 7, the drainage pump 6 is arranged at the bottom of the moat 4, the water inlet end of the sewage pipe 7 is connected to the water outlet of the drainage pump 6, the water outlet end of the sewage pipe 7 of each set of the drainage device is connected to the outside of the slope protection 5 through a drainage main pipe 8, and the water outlet end of the sewage pipe 7 and the water outlet end of the drainage main pipe 8 are both provided with a one-way valve 9, which can effectively block rainwater from approaching the substation area 1 and prevent rainwater from flowing back into the moat 4 along the sewage pipe 7 and the drainage main pipe 8.

[0023] The station enclosure wall 2 adopts a circular ring structure to increase its resistance to external flooding. Two rings of protective walls 3 are installed outside the station enclosure wall 2, each of which is a separate wall. The combined effect of the station enclosure wall 2 and the two rings of protective walls 3 significantly enhances the flood resistance of the station enclosure wall 2. The moat 4 is provided with four rings, enabling multi-ring interception and water storage. Each ring of the moat 4 is 5 meters deep, providing sufficient water storage and interception capacity. Its width is greater than 1 meter, facilitating regular access to the moat 4 for inspection and maintenance of drainage systems and regular cleaning of debris from the bottom of the moat. A ditch cover is positioned above the moat 4, which snaps onto the ditch cover and can be opened during heavy rain to achieve water storage and interception. The slope protection 5 is an arched bridge structure, facilitating the passage of vehicles and pedestrians. The slope protection 5 is ≥500 mm in height, ensuring that floodwater is diverted to the outer edges of the slope protection 5 as much as possible.

[0024] The working principle of this invention is that the retaining wall 5, as a protrusion on the flat ground, acts as a fence, which is equivalent to building a first fence between the substation area 1 and the ground, separating the substation area 1 from the outside world. Multiple circles of moats 4 are set between the outer protective wall 3 and the retaining wall 5, and each circle of moats 4 is equipped with an independent drainage device. In normal weather, the moats 4 are covered by a trench cover to prevent people and vehicles from passing through. In rainy weather, the trench cover can be opened to serve as a trench to prevent rainwater from flooding. Each outer circle of moats 4 can buy time for the inner circle of moats 4. The independent drainage device in each circle of moats 4 can delay and effectively block the approach of rainwater to the substation area 1. The station area wall 2, which serves as the last line of defense, adopts a circular ring structure to increase the wall's ability to withstand external flood pressure. In addition, two circles of arched outer walls 3 are wrapped around the outside of the station area wall 2 of the substation area 1. Each circle of arched outer walls 3 is an independent wall, and when stacked together, they can greatly enhance the flood resistance of the station area wall 2.

[0025] While the embodiments of the present invention have been described above, the above description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
