Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a responsive flood control dike for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects established to reduce the harm of floods and to utilize water resources through development, storage, and drainage. Water conservancy projects rationally control and arrange water resources to achieve their full utilization and allocation. They play a vital role in people's daily production and lives. However, due to the influence and limitations of natural environmental factors, the consequences of a water conservancy project going wrong would be unimaginable. Therefore, we should rationally utilize water conservancy projects to solve a series of practical problems.

[0003] River-related projects refer to engineering projects that involve constructing a series of structures within a river channel, permitted by national flood control standards and other administrative authorities, within the scope of management. River-related projects impose very strict requirements on the structures and also stipulate numerous related safety protection measures and technical management requirements. The development of river-related projects in my country has been on the rise.

[0004] Flood control dikes are embankments built to prevent rivers from overflowing. Most existing flood control dikes along rivers and coastlines are fixed. They are usually set relatively high to prevent flooding caused by heavy rain. This is actually a waste during the non-flood season and affects people's sightseeing of the river environment. Moreover, when there are high floods that are not seen for many years, a lot of manpower and resources are needed to temporarily raise and reinforce the flood control dikes.

[0005] CN 112482303 B discloses a movable flood control dike for water conservancy projects, which can further increase the height of the flood control dike. However, the device requires manual lifting when a flood occurs, and the response speed is relatively slow. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a responsive flood control dike for water conservancy projects.

[0007] The present invention adopts the following technical solution:

[0008] A responsive flood control dike for water conservancy projects includes a flood control wall, a flood control shell, and an extension shell that are sequentially adjacent and slidably connected, a flood control dike base for supporting the flood control wall, and a lever system for operating the relative lifting and lowering of the flood control shell and the extension shell. The lever system has levers that are rotatably connected to a first support column about a joint.

[0009] The first support column is fixed on the flood control dike base and located below the flood control shell. It is slidably connected to the flood control shell, and its top end is located in the cavity inside the flood control shell. A transverse first slide rail is provided on the inner wall of the flood control shell. A first slider is slidably connected in the first slide rail. The first slider is connected to the first end of the lever.

[0010] The extended shell is slidably connected to the flood control shell. A second support column is provided below the extended shell. The second support column is slidably connected to the extended shell. The bottom end of the second support column is fixedly connected to the flood control dike base. The top end passes through the bottom wall of the extended shell and is located in the cavity inside the extended shell. A second slide rail is provided on the second support column. A third slide rail is provided at the second end of the lever. A second slider is slidably connected in both the second slide rail and the third slide rail. The second slider is fixedly connected to the extended shell.

[0011] With the joint as the fulcrum, the first end of the lever is denoted as the effort arm, and the second end is denoted as the resistance arm, where effort × effort arm < resistance × resistance arm.

[0012] Furthermore, the sidewalls of the flood control wall, the flood control shell, and the extended shell that are sequentially adjacent to each other are all parallel to the first support column and are inclined downwards, pointing towards the flood control wall.

[0013] Furthermore, the responsive water conservancy project flood control dike is also equipped with a third support column, which is located below the flood control shell and parallel to the first support column, and the third support column is slidably connected to the flood control shell.

[0014] Furthermore, the responsive water conservancy project flood control dike is also equipped with a U-shaped frame, which is fixedly connected to the inner wall of the flood control shell, and is slidably connected to the first support column and the second support column, with the first slide rail set on the frame.

[0015] Furthermore, the responsive flood control dike is also equipped with a telescopic rod, the top and bottom ends of which are hinged to the lever and the first support column, respectively, and the top end is located between the joint and the second end of the lever.

[0016] Furthermore, the joint is a bearing, with the inner ring of the bearing fixedly connected to the first support column and the outer ring fixedly connected to the lever.

[0017] Furthermore, the length of the resistance arm is greater than the length of the power arm.

[0018] Furthermore, the top wall of the flood control shell is stepped, and the steps point downwards towards the flood control wall.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the water level is shallow, only flood walls and flood-proof shells are needed to block the flood. Once the flood submerges the flood-proof shell, when the flood season arrives and the water level rises and submerges the flood-proof shell, the shell will move downwards due to the gravity of the water. According to the lever principle, the extended shell will be lifted upwards, increasing the height of the flood control. No manual operation is required, and it can respond quickly to the rise of the flood season water level. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments, but this should not be construed as limiting the invention. Unless otherwise specified, the technical means used in the following embodiments are conventional means well known to those skilled in the art, and the materials, reagents, etc. used in the following embodiments are commercially available unless otherwise specified.

[0028] Example 1

[0029] See Figure 1-2This embodiment of a responsive hydraulic engineering flood control dike includes a flood control wall 1, a flood control shell 2, and an extension shell 3 that are sequentially adjacent and slidably connected, a flood control dike base 4 for supporting the flood control wall 1, and a lever system for operating the relative lifting and lowering of the flood control shell 2 and the extension shell 3. The heights of the flood control wall 1, the flood control shell 2, and the extension shell 3 increase sequentially for tiered flood control. The lever system has a lever 5, which is rotatably connected to a first support column 6 around a joint 6. The joint 6 is a bearing, with the inner ring of the bearing fixedly connected to the first support column 6 and the outer ring fixedly connected to the lever 5.

[0030] The first support column 6 is fixed on the flood control dike base 4 and located below the flood control shell 2. It is slidably connected to the flood control shell 2, and its top end is located in the cavity inside the flood control shell 2. There are at least two first support columns 6, which are symmetrically arranged and slidably connected to the two inner walls opposite to the flood control shell 2 respectively. A transverse first slide rail 7 is provided on the inner wall of the flood control shell 2. A first slider 8 is slidably connected in the first slide rail 7. The first slider 8 is connected to the first end of the lever 5.

[0031] The extended shell 3 is slidably connected to the flood control shell 2. A second support column 9 is provided below the extended shell 3. The second support column 9 is slidably connected to the extended shell 3. The bottom end of the second support column 9 is fixedly connected to the flood control dike base 4. The top end passes through the bottom wall of the extended shell 3 and is located in the cavity inside the extended shell 3. There are at least two second support columns 9, which are symmetrically arranged and slidably connected to the two inner walls opposite to the extended shell 3 respectively. A second slide rail 10 is provided on the second support column 9. A third slide rail 11 is opened at the second end of the lever 5. A second slider 12 is slidably connected in the second slide rail 10 and the third slide rail 11. The second slider 12 is fixedly connected to the extended shell 3.

[0032] Using joint 6 as the fulcrum, the first end of lever 5 is denoted as the effort arm, and the second end as the resistance arm. Effort × Effort Arm < Resistance × Resistance Arm, meaning that in a static state without external force, the first end of lever 5 is in a high position, and the second end is in a low position. At this time, the bottoms of the flood control shell 2 and the extended shell 3 are at the same height, and there is a gap between them and the flood control dike base 4, the length of which is less than the height of the flood control wall 1. When the length of the effort arm equals the length of the extension shell 3, the weight of the extension shell 3 is increased to be greater than the mass of the flood control shell 2 by adding counterweights, thus ensuring that effort × effort arm < resistance × resistance arm.

[0033] Working principle:

[0034] During the non-flood season, the water level is low, and only the flood wall 1 and the flood shell 2 are needed to block it. When the flood season arrives, the water level rises and submerges the flood shell 2. The gravity of the water plus the gravity of the flood shell 2 constitutes the driving force. When the driving force × driving arm > resistance × resistance arm, the lever 5 will rotate, raising the extended shell 3. In this way, it can respond quickly when the water level rises during the flood season.

[0035] In this embodiment, a telescopic rod is also provided. The top and bottom ends of the telescopic rod 15 are hinged to the lever 5 and the first support column 6, respectively, and the top end is located between the joint 6 and the second end of the lever 5. The telescopic rod is preferably a damped telescopic rod, which is existing technology, and its specific structure will not be described in detail here. The purpose of providing the telescopic rod is to prevent rapid changes in water level from causing excessive rotational inertia of the lever 5, which could damage the connecting components.

[0036] Example 2

[0037] See Figure 3-4 This embodiment of a responsive flood control dike for water conservancy projects includes a flood control wall 1, a flood control shell 2, and an extension shell 3 that are sequentially adjacent and slidably connected, a flood control dike base 4 for supporting the flood control wall 1, and a lever system for operating the relative lifting and lowering of the flood control shell 2 and the extension shell 3. The heights of the flood control wall 1, the flood control shell 2, and the extension shell 3 increase sequentially for tiered flood control. The lever system has a lever 5, which is rotatably connected to a first support column 6 around a joint 6. The joint 6 is a bearing, with the inner ring of the bearing fixedly connected to the first support column 6 and the outer ring fixedly connected to the lever 5.

[0038] The first support column 6 is fixed on the flood control dike base 4 and located below the flood control shell 2. It is slidably connected to the flood control shell 2, and its top end is located in the cavity inside the flood control shell 2. There are at least two first support columns 6, which are symmetrically arranged and slidably connected to the two inner walls opposite to the flood control shell 2 respectively. A transverse first slide rail 7 is provided on the inner wall of the flood control shell 2. A first slider 8 is slidably connected in the first slide rail 7. The first slider 8 is connected to the first end of the lever 5.

[0039] The extended shell 3 is slidably connected to the flood control shell 2. A second support column 9 is provided below the extended shell 3. The second support column 9 is slidably connected to the extended shell 3. The bottom end of the second support column 9 is fixedly connected to the flood control dike base 4. The top end passes through the bottom wall of the extended shell 3 and is located in the cavity inside the extended shell 3. There are at least two second support columns 9, which are symmetrically arranged and slidably connected to the two inner walls opposite to the extended shell 3 respectively. A second slide rail 10 is provided on the second support column 9. A third slide rail 11 is opened at the second end of the lever 5. A second slider 12 is slidably connected in the second slide rail 10 and the third slide rail 11. The second slider 12 is fixedly connected to the extended shell 3.

[0040] With joint 6 as the fulcrum, the first end of lever 5 is denoted as the effort arm, and the second end is denoted as the resistance arm. Effort × effort arm < resistance × resistance arm.

[0041] In this embodiment, a telescopic rod is also provided. The top and bottom ends of the telescopic rod 15 are hinged to the lever 5 and the first support column 6, respectively, and the top end is located between the joint 6 and the second end of the lever 5.

[0042] The responsive flood control dike of this embodiment is also equipped with a third support column 13 and a U-shaped frame 14. The third support column 13 is located below the flood control shell 2 and parallel to the first support column 6. The third support column 13 is slidably connected to the flood control shell 2, and the frame 14 is fixedly connected to the inner wall of the flood control shell 2. The frame 14 is slidably connected to the first support column 6 and the second support column 9, and a first slide rail 7 is provided on the frame 14. This arrangement can increase the stability of the flood control shell 2 when it slides.

[0043] In this embodiment, the side walls of the flood control wall 1, the flood control shell 2, and the extension shell 3 are parallel to each other and inclined to the first support column 6, with the downward inclination pointing towards the flood control wall 1. This arrangement can decompose part of the force required to lift the extension shell 3 horizontally, so that the lever 5 can rotate even when the water level below the flood control shell 2 is low.

[0044] In this embodiment, the length of the resistance arm is greater than the length of the power arm. This arrangement allows the extension shell 3 to rise for a greater distance than the flood control shell 2 to descend, thus maximizing the height of the extension shell 3.

[0045] Example 3

[0046] See Figure 5 This embodiment of the responsive hydraulic engineering flood control dike is basically the same as that in embodiment 2, except that the top wall of the flood control shell 2 is stepped, and the downward direction of the steps points towards the flood control wall 1. This design can prevent the water level from rising too quickly and submerging the extended shell 3, thus preventing the lever 5 from rotating normally.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.
