Description

Technical Field

[0001] This application relates to the field of steel dams, and particularly to a noise-reducing steel dam with a silt removal function. Background Art

[0002] In the field of water conservancy and hydropower construction, with the increase in urban water use, landscape construction, environmental improvement, irrigation, and power generation demands, various types of sluice gates have been widely used. Among them, rubber dams, flap gates, and flat plate lifting sluice gates are relatively common structural forms. These traditional sluice gates have their own advantages in different application scenarios. For example, due to its flexible structure, the rubber dam can, to a certain extent, adapt to the irregular shape of the river bottom. However, these traditional gate structures also have many limitations. For example, during the operation of the rubber dam, it is necessary to fill or inflate the dam to raise it, and to drain water or deflate it to collapse the dam, which is a time-consuming process and affects the rapid cut-off of water flow or the timely discharge of floods. In addition, due to the easy aging of rubber materials, quality accidents may occur during long-term use, resulting in higher maintenance costs and potential safety hazards.

[0003] To address the deficiencies of traditional rubber dams, a large number of steel structure gates and flap gates have gradually emerged on the market. These steel dam structures have shown certain advantages in wider river applications due to their high strength and durability. As a new type of adjustable air-controlled overflow gate, the steel dam gate usually consists of a civil structure, a steel gate body with a fixed shaft, and a hoisting device, and is particularly suitable for working conditions with a wider sluice opening and a smaller water level difference. However, despite the certain advantages in design, such as it can achieve a wider sluice opening layout, reduce civil engineering investment, have the ability of two-way water retaining and flexible opening and closing, and can improve the river landscape to form an artificial waterfall effect, there are still some problems in actual applications.

[0004] With the increasing application of steel dam gates in urban river landscapes, related problems have gradually emerged. Especially in the urban environment, the noise generated by night overflow has a greater impact on the rest of the surrounding residents, which has become an urgent problem to be solved.

[0005] In view of the existence of the above problems, it is of great practical significance and application value to develop a noise-reducing steel dam with a silt removal function and capable of effectively reducing noise. Utility Model Content

The steel dam includes a bottom plate, side piers on both sides of the bottom plate, a main dam assembly installed on the bottom plate and cooperating with the two side piers, and a secondary dam assembly installed on one side of the main dam assembly.

[0011] Furthermore, both the first driving unit and the second driving unit are hydraulic arms; the first driving unit drives the main shaft to rotate, thereby controlling the lifting of the gate leaf; the second driving unit drives the secondary shaft to rotate, thereby controlling the opening and closing of the secondary gate leaf for the secondary flow channel.

[0012] In some embodiments, a semi-circular support bearing cooperating with the main shaft is provided in the installation groove.

[0030] As Figures 1 to 6 shown, this embodiment details the structural composition of a noise-reducing steel dam with a silt removal function, the connection and cooperation relationships of its various components, and its working principle, and provides a detailed description in combination with specific usage scenarios, especially in preventing overflow and achieving noise reduction.

[0031] In terms of structural composition, the steel dam is composed of a bottom plate 1, side piers 2, a main dam assembly 3, and a secondary dam assembly 4. The bottom plate 1 is located in the central part of the steel dam, and side piers 2 are provided on both sides thereof. A main flow channel 5 is formed between the bottom plate 1 and the side piers 2 through tight cooperation for the control and guidance of water flow.

[0032] Both ends of the main dam assembly 3 are hermetically fitted with the side piers 2, so that the main dam assembly 4 is installed on the bottom plate 1 and cooperates with the side piers 2 on both sides to achieve controllable water blocking and sealing of the main flow channel 5.

[0033] The secondary dam assembly 4 is installed on one side of the main dam assembly 1 and is used to conduct a secondary flow channel 6 under specific circumstances to avoid or reduce the noise generated by water overflowing the main dam.

[0034] The main dam assembly 3 is the core part of this steel dam and is responsible for controlling and sealing the water flow in the main flow channel 5. This assembly includes key components such as a main shaft 301, a gate leaf 302, a sealing rotating shaft 303, and a water stop rubber strip 304. These components work together to achieve controllable water blocking and sealing of the water flow.

[0035] The main shaft 301 is fixed in the installation groove 101 of the bottom plate 1 through the sealed rotating shafts 303 arranged at both ends, which are usually made of high-strength stainless steel or alloy steel to ensure stability and durability under long-term operation and high water pressure environment. The two ends of the main shaft 301 cooperate with the two side piers 2 through sealed bearings, so that the main shaft 301 is in the installation groove 101 and is aligned with the edge of the installation groove 101. At the same time, it is auxiliaryly supported by the semicircular support bearings in the installation groove 101. The semicircular support bearing design reduces the structural stress of the sealed bearings at both ends when the main shaft is long, reduces friction and wear, and prolongs its service life.

[0036] The gate leaf 302 is the main water retaining component of the main dam assembly 3, which is connected to the main shaft 301 and is raised and lowered with the rotation of the main shaft 301, thereby controlling the passage or blocking of water flow. The gate leaf 302 is made of corrosion-resistant metal materials, such as stainless steel or aluminum alloy, to resist corrosive substances in the water flow.

[0037] The two sides of the gate leaf 302 and the inner side of the side pier 2 are sealed by the waterproof rubber strip 304 to ensure that the water flow in the main channel 5 will not leak or overflow. This sealing design not only effectively prevents the water flow from passing through the gaps on both sides of the main dam, but also avoids or reduces the overflow noise by conducting the secondary flow channel 6 when the main dam assembly 3 is closed, thereby achieving a noise reduction effect.

[0038] When it is necessary to block the water flow, the first drive unit 305 drives the main shaft 301 to rotate, and the door leaf 302 rotates downward with the main shaft 301, and finally seals with the bottom plate 1 and the side pier 2 to achieve complete closure of the main channel 5. When it is necessary to release the water flow or adjust the water level, the main shaft 301 rotates in the opposite direction, and the door leaf 302 rises accordingly, opening the main channel 5 and allowing the water flow to pass through.

[0039] The auxiliary dam assembly 4 is installed on one side of the main dam assembly 3, and is mainly used to conduct the auxiliary flow channel 6 under certain circumstances to avoid or reduce the noise caused by the overflow of water from the main dam, and at the same time has a certain silt removal function. The main components of the auxiliary dam assembly 4 include a secondary shaft 401, an auxiliary door leaf 402, a support rib 403 and a second drive unit 404.

[0040] The secondary shaft 401 is the core component of the secondary dam assembly 4, responsible for supporting and driving the secondary door leaf 402. The secondary shaft 401 is usually made of high-strength corrosion-resistant materials, such as stainless steel or wear-resistant alloy steel, to ensure durability and stability in long-term water flow scouring and corrosion environments. The secondary shaft 401 is controlled to rotate by the second drive unit 404, thereby realizing the opening and closing operations of the secondary door leaf 402.

[0041] More specifically, the auxiliary gate leaf 402 is connected to the auxiliary shaft 401, and is a component in the auxiliary dam assembly 4 that directly contacts the water flow, and is responsible for controlling the opening and closing of the auxiliary flow channel 6. The material of the auxiliary gate leaf 402 is usually selected from corrosion-resistant metals, such as stainless steel or aluminum alloy, to ensure that it is not corroded under the action of long-term water flow, while maintaining structural strength. When the auxiliary gate leaf 402 is in a closed state, the auxiliary flow channel 6 is sealed; when the auxiliary gate leaf 402 is opened, the auxiliary flow channel 6 is connected, allowing water to flow through, thereby reducing the overflow phenomenon at the top of the main dam and significantly reducing the generation of overflow noise. Especially at night or when the flow rate is large, the overflow is reduced by opening the auxiliary flow channel 6, which significantly reduces the noise generated by the overflow of water from the main dam.

[0042] At least one rubber strip is installed on the outer edge of the auxiliary door leaf 402 to form a seal with the opening of the auxiliary flow channel 6, and is usually made of a highly elastic and wear-resistant material, such as synthetic rubber or polyurethane. The role of the rubber strip is to ensure that the auxiliary door leaf 402 can effectively seal the auxiliary flow channel 6 when it is closed to prevent water leakage, thereby enhancing the sealing and reliability of the auxiliary dam assembly 4.

[0043] In order to enhance the structural rigidity of the auxiliary door leaf 402, the auxiliary door leaf 402 is connected to the auxiliary shaft 401 through a plurality of support ribs 403. These support ribs 403 help to maintain the stability of the auxiliary door leaf 402 under the impact of water flow and prevent deformation or damage caused by external forces. The support ribs 403 are usually made of the same metal material as the auxiliary door leaf 402 to ensure that the strengths of the two are matched and they can jointly resist the impact of water flow.

[0044] The implementation process and actions of this implementation are as follows: In the urban river landscape, the application scenarios of the noise reduction steel dam include landscape maintenance during the day and noise reduction needs at night. During the day, the steel dam is usually in a raised dam state, forming a beautiful artificial waterfall for citizens to enjoy. However, at night or when the water flow is large, the water may overflow from the top of the main dam, generating obvious noise and affecting the rest of the surrounding residents. At this time, the role of the auxiliary dam component is very important.

[0045] Or when the overflow noise exceeds the set environmental noise standard, the hydraulic drive unit of the auxiliary dam assembly 4 will start, drive the secondary shaft 401 to rotate, and gradually open the auxiliary gate leaf 402 to conduct the auxiliary flow channel 6. Through the opening of the secondary flow channel 6, part of the water flow is guided to flow out through the secondary flow channel 6, thereby reducing the overflow at the top of the main dam and significantly reducing the overflow noise.

[0046] In addition, the design of the secondary flow channel 6 is not only used for noise reduction, but also can effectively discharge silt when opened, preventing silt from accumulating in the main flow channel 5 or the secondary flow channel 6 and affecting the normal operation of the steel dam. Through the precise control of the secondary dam component 4, the steel dam can provide efficient noise reduction and silt removal functions without affecting the normal water flow control function.

[0047] In this embodiment, the noise-reducing steel dam with a silt drainage function realizes efficient water flow control, noise reduction, and silt drainage functions through the coordinated cooperation of the main dam component 3 and the auxiliary dam component 4.

[0048] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims.
