Description

Technical Field

[0001] This application relates to the field of municipal engineering technology, and in particular to a drainage and flood control structure for municipal engineering. Background Technology

[0002] Traditional drainage and flood control structures are often designed with a focus on simple water flow guidance, and their filtration devices typically use rudimentary filter plates. When extreme weather events such as torrential rains occur, the rainwater flow increases dramatically and carries large amounts of debris from the urban surface, such as branches, garbage, and silt. This debris easily accumulates at the filter plates. Because the pore size of the filter plates is relatively fixed and lacks an effective self-cleaning or anti-clogging mechanism, once debris adheres, it is difficult to remove, quickly leading to filter plate blockage.

[0003] Meanwhile, existing drainage and flood control structures have extremely limited means to address drainage blockages. They typically rely on periodic manual cleaning or simple mechanical dredging tools, methods that are not only inefficient but also ineffective in handling urgent drainage needs. For example, in the event of urban flooding, manual cleaning is often insufficient, and mechanical dredging tools may be ineffective due to the complex layout of drainage pipes and the stubborn nature of blockages, severely impacting drainage efficiency. This leads to severe flooding on urban roads, traffic paralysis, significant disruption to residents' lives, and even potential damage to urban infrastructure and buildings, endangering urban safety. Utility Model Content

[0004] To address the problem that traditional drainage and flood control structures are prone to filter plate blockage due to heavy rain and debris, and lack effective dredging measures, thus failing to resolve drainage issues in a timely manner, this application provides a drainage and flood control structure for municipal engineering.

[0005] The drainage and flood control structure for municipal engineering provided in this application adopts the following technical solution:

[0006] A drainage and flood control structure for municipal engineering includes a vertical shaft. A side-drainage assembly is provided on the outside of the vertical shaft. The side-drainage assembly includes a sleeve provided on the outside of the vertical shaft. A filter screen is provided between the sleeve and the vertical shaft. Water inlets are provided on both the upper and lower sides of the filter screen on the vertical shaft. A filter assembly is provided inside the vertical shaft. The filter assembly includes a filter plate provided inside the vertical shaft, and the filter plate can move along the axial direction of the vertical shaft. A dredging assembly is provided on the lower side of the filter plate. The dredging assembly includes a support frame provided on the lower side of the filter plate. A plurality of dredging pipes adapted to the filter plate are provided on the support frame.

[0007] Preferably, a rain grate is provided at the top of the shaft.

[0008] Preferably, the bottom of the filter plate is provided with a sealing sleeve, which is slidably connected to the inside of the vertical shaft. The height of the sealing sleeve is greater than the height of a single water inlet and less than the vertical distance between the upper and lower water inlets.

[0009] Preferably, the bottom of the support frame is provided with a plurality of columns, and the lower end of the columns is provided with a bracket. The bracket is detachably installed on the inner wall of the shaft and is located above the lower water inlet.

[0010] Preferably, the bracket is provided with a support assembly, the support assembly including a telescopic sleeve disposed on the bracket, the movable end of the telescopic sleeve slidingly passing through the support frame and detachably connected to the filter plate, and a spring being disposed on the inner side of the telescopic sleeve.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By using a combination of vertical shafts, rainwater grates, side drainage components, filter components, unblocking components, and support components, when the filter plate is blocked or the water flow is low, resulting in water accumulation above the filter plate, the pressure of the accumulated water on the filter plate compresses the telescopic sleeve and spring. The sealing sleeve is located between the upper and lower water inlets, and the filter plate continues to move downward, exposing the upper water inlet, achieving side drainage and preventing blockage and flooding. If the water level above the sealing sleeve still rises, the filter plate continues to move downward, allowing the unblocking pipe to pass through the filter plate's filter holes to clean and unclog the filter plate. The simultaneous drainage by the filter plate and filter screen can further prevent blockage and flooding. Compared with existing technologies, it has the advantages of better drainage and flood prevention effects and the ability to promptly unclog drainage blockages. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0018] This application discloses a drainage and flood control structure for municipal engineering. (Refer to...) Figure 1-3 The drainage and flood control structure used in municipal engineering mainly consists of vertical shafts, rainwater grates, side drainage components, filter components, dredging components, and support components, which can promptly dredge drainage blockages and ensure efficient operation of drainage and flood control.

[0019] Reference Figure 2 Vertical shaft 1, as the core of the entire drainage and flood control structure, is made of high-strength concrete, possessing excellent sealing and stability. The rainwater grate 2, installed at the top of vertical shaft 1, is made of metal, offering strength and corrosion resistance. Its function is to prevent debris from entering the vertical shaft, avoiding the accumulation of larger debris that could affect drainage. Simultaneously, the rainwater grate allows rainwater to flow smoothly into the vertical shaft, acting as a preliminary filter.

[0020] Reference Figure 2 The side drainage component 3 includes a sleeve 301 and a filter screen 301, installed on the outside of the shaft 1. A filter screen 302 is installed between the sleeve 301 and the shaft 1. The filter screen is made of corrosion-resistant metal material, and its arc-shaped structure design better conforms to the outer surface of the shaft, increasing the filtration area. The mesh size of the filter screen is designed according to actual drainage needs to ensure filtration effectiveness. The connection method between the sleeve 301 and the shaft 1 ensures the stability of the side drainage component, allowing rainwater to enter the shaft through the filter screen while preventing debris from entering the shaft.

[0021] Reference Figure 2 The filter assembly 4, installed inside the vertical shaft 1, includes a filter plate 401 and a sealing sleeve 402. The filter plate is an inverted arc-shaped plate or a conical cylinder, a design that effectively increases the filtration area and improves filtration efficiency. The bottom of the filter plate 401 is fitted with a sealing sleeve 402, which slides within the vertical shaft 1, providing excellent sealing and sliding performance. The height of the sealing sleeve is greater than the height of a single water inlet and less than the vertical distance between the upper and lower water inlets, ensuring that the filter plate effectively seals the upper and lower water inlets during movement, preventing water accumulation above the filter plate from leaking through the water inlets, while also providing stable support for the movement of the filter plate.

[0022] Reference Figure 3The unblocking component 5 includes a support frame 501, an unblocking pipe 502, a column 503, and a bracket 7. The support frame 501 is located below the filter plate 401. Its structural design supports the filter plate 401 and, when the filter plate moves downwards, drives the unblocking pipe to clean and unclog it. The support frame has filter holes, allowing accumulated water on the filter plate to flow into the shaft. The unblocking pipe is a hollow pipe with an inclined top that fits with the filter plate. Its design allows the unblocking pipe to pass through the filter holes of the filter plate when it moves downwards, cleaning and unclogging it and ensuring the filtration effect. A bracket 7 is installed at the lower end of the column 503. The bracket 7 is detachably installed on the inner wall of the shaft 1 and is located above the lower water inlet. The function of the bracket 7 is to support the support frame and the filter plate, ensuring their stable position within the shaft.

[0023] Reference Figure 3 The support assembly 6 includes a telescopic sleeve 601 and a spring 602. The movable end of the telescopic sleeve 601 slides through the support frame 501 and is detachably connected to the filter plate 401. The spring 602 is located inside the telescopic sleeve 601. When water accumulates above the filter plate, the water exerts pressure on the filter plate, compressing the telescopic sleeve 601 and the spring 602, allowing the filter plate to move stably downwards under the water pressure. The elastic coefficient of the spring 602 is designed according to the pressure and movement requirements of the filter plate, ensuring that the filter plate can move smoothly under the water pressure, while providing a certain buffering force to prevent the filter plate from being subjected to excessive impact during movement.

[0024] The implementation principle of a drainage and flood control structure for municipal engineering in this application embodiment is as follows: In a municipal engineering drainage and flood control scenario, when rainwater enters the vertical shaft 1 through the rainwater grate 2, the filter plate 401 filters the rainwater. When the filter plate is clogged or the water flow is small, the accumulated water above the filter plate 401 will exert pressure on the filter plate 401.

[0025] Because the height of the sealing sleeve 402 is greater than the height of a single water inlet and less than the vertical distance between the upper and lower water inlets, under the pressure of accumulated water, the filter plate 401 compresses the telescopic sleeve 601 and the spring 602, causing the filter plate 401 to move downward. When the filter plate 401 moves down to a certain extent, the upper inlet is exposed, and rainwater is discharged from the side, achieving drainage and flood prevention.

[0026] As the water level continues to rise, the filter plate 401 moves further downward, and the unblocking pipe 502 passes through the filter holes of the filter plate 401 to clean and unclog the filter plate. The filter plate and the filter screen drain water simultaneously, improving drainage efficiency and preventing blockages and flooding.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
