Description

Technical Field

[0001] This utility model belongs to the field of substations, and in particular relates to a rainwater sedimentation and infiltration tank for substations. Background Technology

[0002] Existing substation sites generally lack drainage points, and rainwater runoff does not meet soil and water conservation requirements. Therefore, infiltration ponds are typically installed outside the substation. Even in the few substations equipped with traditional rainwater infiltration ponds, which initially provide good infiltration, over the years, windy and sandy weather causes grass seeds to fall into the ponds, leading to vegetation growth and impairing infiltration. If a closed sedimentation tank is constructed, there is no evaporation during sunny days, but rainwater overflows easily during the rainy season. Utility Model Content

[0003] In view of this, the present invention aims to propose a rainwater sedimentation and infiltration tank for substations to solve the technical problems of traditional infiltration tanks being overgrown with plants and having poor infiltration effect.

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

[0005] A rainwater sedimentation and infiltration tank for a substation includes: a sedimentation tank, a sludge discharge well, and an infiltration tank;

[0006] The sedimentation tank is connected to the rainwater output from the substation through an inlet pipe, and the rainwater after sedimentation is fed into the infiltration tank, while the sedimented silt is discharged into the sludge discharge well.

[0007] The bottom of the sedimentation tank is connected to the sludge pump in the sludge discharge well via a sludge discharge pipe. The sludge discharge well is used to collect and discharge the sludge output by the sludge pump.

[0008] The inner wall of the sedimentation tank is connected to the infiltration tank, and the top of the sedimentation tank is provided with a sedimentation cover plate.

[0009] The top of the seepage pool has a seepage cover that can be opened and closed.

[0010] Furthermore, the bottom of the infiltration pool is provided with a plain soil layer, a 100mm graded crushed stone layer, and a 200mm graded crushed stone layer in sequence from bottom to top. The plain soil layer is compacted with a compaction coefficient of not less than 0.93.

[0011] Furthermore, the sediment cover plate is a reinforced concrete cover plate.

[0012] Furthermore, the bottom of the sedimentation tank is funnel-shaped.

[0013] Furthermore, the seepage cover is an electrically telescopic cover.

[0014] Furthermore, the cross-section of the infiltration pool is rectangular.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By placing a sedimentation tank and a sludge discharge well before the infiltration tank, and installing a seepage cover to prevent wind erosion and sand seeding, these design elements combined improve the water quality of the infiltration tank, extend its maintenance cycle, and maximize its infiltration effect. The sedimentation tank is connected to a sludge discharge pump, and the sludge discharge well allows for manual sludge removal based on the sediment level, extending the manual maintenance cycle of the infiltration tank. The addition of a seepage cover to the infiltration tank allows for increased evaporation under clear, calm weather conditions. During rainy or windy weather, the seepage cover is closed, reducing the amount of water entering the evaporation tank during heavy rain and minimizing the entry of grass seeds and airborne sediment into the infiltration tank during windy conditions. This further extends the maintenance cycle of the infiltration tank and ensures optimal infiltration performance. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0023] See Figure 1 The rainwater sedimentation and infiltration tank for a substation shown includes a sedimentation tank 1, a sludge discharge well 2, and an infiltration tank 3.

[0024] Sedimentation tank 1 is connected to the rainwater output from the substation via an inlet pipe. The settled rainwater is then fed into infiltration tank 3, where the settled sediment is discharged into sludge discharge well 2. The substation's rainwater is typically collected by the site's rainwater system during rainfall and transported to sedimentation tank 1. After filtering the sediment, sedimentation tank 1 discharges it into the infiltration tank. This pre-sedimentation tank facilitates sediment settling, significantly improving the water quality entering the rainwater infiltration tank.

[0025] The bottom of the sedimentation tank 1 is connected to the sludge pump 21 in the sludge discharge well 2 via a sludge discharge pipe. The sludge discharge well 2 is used to collect and discharge the sludge output by the sludge pump 21. Sludge can be manually discharged periodically, or the output port of the sludge pump can be connected to an external container for collecting sludge. The upper part of the inner wall of the sedimentation tank 1 is connected to the infiltration tank 3, and the top of the sedimentation tank 1 is equipped with a sedimentation cover plate 11.

[0026] Preferably, the bottom of the sedimentation tank 1 is funnel-shaped, which is conducive to the concentrated collection of sediment.

[0027] Preferably, the sedimentation cover 11 is a reinforced concrete cover. This saves costs.

[0028] The top of the infiltration pool 3 has an infiltration cover 31 that can be opened and closed, mainly serving to cover the infiltration pool 3. The shape of the top of the infiltration pool 3 is not limited, and is matched to the structure of the infiltration cover 31. Compared to using a closed infiltration pool, there is no evaporation on sunny days, and the overflow of rainwater is large during continuous rainy days. This new invention allows the infiltration cover 31 to be opened under sunny weather conditions, increasing rainwater evaporation and preventing rainwater overflow during the rainy season. The infiltration cover 31 is prior art; see Chinese invention patent application number CN202211090434.6, entitled "An Electric Telescopic Canopy Roof with Ventilation and Dust Removal Structure for Building Construction," and Chinese utility model patent application number CN202023329777.2, entitled "A New Type of Electric Telescopic Canopy Sealing Cover."

[0029] Preferably, the cross-section of the infiltration tank 3 is rectangular. This design reduces the project's land area, and the rectangular design also reduces the area of ​​land required for external acquisition.

[0030] Preferably, the seepage cover 31 is an electrically retractable cover. That is, there is no need to manually close or open the cover, thus improving efficiency.

[0031] Preferably, the bottom of the infiltration tank 3 is provided with a soil layer, a 100mm graded crushed stone layer, and a 200mm graded crushed stone layer from bottom to top. The soil layer is compacted, and the compaction coefficient is not less than 0.93. With this design, the top three layers of the infiltration tank 3 are a soil layer, a 100mm graded crushed stone layer, and a 200mm graded crushed stone layer, which makes the structure stable.

[0032] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not exhaustively describe all details, nor do they limit the present invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
