Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a foldable and portable temporary cofferdam for water conservancy projects. Background Technology

[0002] In the construction of water conservancy projects, temporary cofferdams play an irreplaceable and crucial role as temporary water-retaining structures. In various water conservancy projects such as river regulation and dam construction, the construction area is often located in a flowing environment. Temporary cofferdams can effectively cut off the water flow, isolating the construction area from external water bodies and creating a dry construction environment. This dry environment not only facilitates earthwork excavation, foundation pouring, and equipment installation for construction workers, but also ensures the normal operation of construction equipment, significantly improving construction efficiency and quality. Currently, traditional cofferdams cannot flexibly adjust their shape to fit the boundaries of irregular construction areas, resulting in poor water-retaining effects, potential seepage risks, and impacting the construction progress and quality of water conservancy projects.

[0003] Therefore, it is necessary to provide a new foldable and portable temporary cofferdam for water conservancy projects to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a foldable and portable temporary cofferdam for water conservancy projects is provided to solve the above-mentioned problems.

[0005] The foldable and portable temporary cofferdam for water conservancy projects provided by this utility model includes: two mounting brackets; the two mounting brackets are arranged opposite each other, and multiple barriers are provided between the two mounting brackets, with the side of the two edge barriers that are relatively far apart connected to the mounting brackets respectively; wherein, a rotating component is provided between each two adjacent barriers, and the angle between the two barriers can be adjusted by the rotating component; a locking component is provided above each rotating component, so that the barrier after the angle is adjusted can be fixed by the locking component.

[0006] Preferably, the rotating component includes two adjusting frames disposed between two enclosures. The two adjusting frames are arranged opposite to each other, and each adjusting frame is rotatably connected to an adjusting shaft on its relatively far side. The relatively far sides of the two adjusting shafts are respectively connected to the enclosures.

[0007] Preferably, a rotating shaft is provided between the two adjusting frames, and a rotating platform is connected to the top and bottom of the two rotating shafts. Guide blocks are connected to the top and bottom of the two adjusting frames on the relatively close side, and guide grooves corresponding to the guide blocks are opened on the outer side of the two rotating platforms.

[0008] Preferably, the two ends of the two adjustment frames that are relatively close to each other are connected to a protective cloth, and the protective cloth is located on both sides of the rotating shaft.

[0009] Preferably, the locking component includes two locking rods, both ends of which are provided with bent portions, and the top of each of the two adjusting frames is provided with multiple locking grooves corresponding to the two bent portions.

[0010] Preferably, both mounting brackets have multiple locking slots at their tops, and the two mounting brackets can be engaged with the locking slots via locking rods.

[0011] Compared with related technologies, the foldable and portable temporary cofferdam for water conservancy projects provided by this utility model has the following beneficial effects:

[0012] This invention allows the enclosure to be flexibly adjusted in angle by setting rotating parts between adjacent enclosures. The cofferdam can be quickly adjusted in shape according to the actual conditions of the construction site, such as terrain and water flow direction, to fit the irregular boundary of the construction area, greatly improving the water blocking effect. At the same time, this foldable design allows the cofferdam to be folded and stored when not in use, greatly reducing its volume, making it easy to transport and handle, reducing construction costs, and improving construction efficiency. It is especially suitable for scenarios where multiple construction sites are moved around.

[0013] This utility model, through the setting of locking components, can firmly fix the enclosure after the enclosure angle is adjusted by the locking rod engaging with the locking groove, preventing the enclosure from rotating or displacing under the impact of water flow or other external forces, thus ensuring the stability of the overall structure of the cofferdam and the reliability of its water-blocking function, and providing a safe and stable working environment for water conservancy project construction.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] This utility model provides a foldable and portable temporary cofferdam for water conservancy projects. The foldable and portable temporary cofferdam for water conservancy projects includes: two mounting brackets 1; the two mounting brackets 1 are arranged opposite each other, and multiple barriers 11 are arranged between the two mounting brackets 1, with the side of the two edge barriers 11 that is relatively far apart connected to the mounting brackets 1 respectively; wherein, a rotating component is provided between every two adjacent barriers 11, and the angle between the two barriers 11 can be adjusted by the rotating component; a locking component is provided above each rotating component, so that the barrier 11 after the angle is adjusted can be fixed by the locking component.

[0022] It should be noted that: Mounting bracket 1 is the basic support component of the entire temporary cofferdam. Two mounting brackets 1 are arranged opposite each other, stabilizing both ends of the temporary cofferdam and providing reliable end support for the entire cofferdam structure, allowing the entire cofferdam to be firmly placed in the construction area of ​​the hydraulic engineering project. The retaining wall 11 is the main water-blocking component of the temporary cofferdam. Multiple retaining walls 11 are set between two mounting brackets 1, collectively forming a barrier to block water flow. The relatively distant sides of the retaining walls 11 located at the two edges are connected to the mounting brackets 1, ensuring that the retaining walls 11 form a continuous water-blocking structure between the mounting brackets 1. Rotating components are installed between every two adjacent retaining walls 11, giving the retaining walls 11 rotatability. The angle between two retaining walls 11 can be adjusted through these rotating components. This feature allows the temporary cofferdam to be flexibly shaped according to the terrain and water flow conditions of the actual construction area. Locking components located above each rotating component play an important role after the retaining wall 11 has been adjusted to the correct angle through the rotating components. Once the enclosure 11 is adjusted to a suitable angle according to actual needs, it can be fixed in place by locking components. This prevents changes in the angle between the enclosure 11 due to water flow impact or other external forces during use, thus ensuring the stability of the temporary cofferdam structure and the reliability of its water-blocking effect.

[0023] In an embodiment of this utility model, the rotating component includes two adjusting frames 2 disposed between two enclosures 11. The two adjusting frames 2 are arranged opposite each other. An adjusting shaft 21 is rotatably connected to the relatively far side of each of the two adjusting frames 2. The relatively far side of each of the two adjusting shafts 21 is connected to the enclosure 11 respectively. A rotating shaft 22 is disposed between the two adjusting frames 2. A rotating platform 23 is connected to the top and bottom of each of the two rotating shafts 22. A guide block 24 is connected to the top and bottom of the relatively close side of each of the two adjusting frames 2. A guide groove 25 corresponding to the guide block 24 is opened on the outer side of each of the two rotating platforms 23. A protective cloth 26 is connected to both ends of the relatively close side of each of the two adjusting frames 2, and the protective cloth 26 is located on both sides of the rotating shaft 22.

[0024] It should be noted that the two adjusting frames 2 are arranged opposite to each other between the two enclosures 11, and are the basic structural components of the rotating parts. The function of the adjusting shaft 21 is to realize the rotational connection between the adjusting frame 2 and the enclosure 11, so that the enclosure 11 can rotate around the adjusting shaft 21 as the axis. This provides a basic rotational connection method for adjusting the angle between the enclosures 11, ensuring the flexibility and stability of the enclosure 11's rotation. The rotating shaft 22 allows the two adjusting frames 2 to rotate around it, thereby driving the connected enclosure 11 to change its angle. It plays a core rotational support role in the angle adjustment process of the enclosure 11, ensuring the smoothness and stability of the adjustment process. The function of the rotating table 23 is to provide a stable rotational connection structure for the rotating shaft 22, and through cooperation with the guide block 24 and the guide groove 25, it plays a guiding and limiting role in the rotation of the adjusting frame 2. The guide groove 25 cooperates with the guide block 24 to provide a guiding path for the rotation of the adjusting frame 2, enabling the adjusting frame 2 to rotate along a predetermined direction and angle. Protective cloth 26 is connected to both ends of the two adjusting frames 2 on opposite sides, and the protective cloth 26 is located on both sides of the rotating shaft 22. The protective cloth 26 mainly serves to protect and seal, and is made of elastic material. On the one hand, it prevents debris, mud, and other contaminants from entering the gaps between rotating components such as the rotating shaft 22, avoiding wear or jamming of these components and affecting the rotation adjustment of the enclosure 11; on the other hand, the protective cloth 26 can, to a certain extent, provide a seal, reducing water leakage from the gaps between the adjusting frames 2 and improving the water-blocking effect of the cofferdam.

[0025] In an embodiment of this utility model, the locking component includes two locking rods 3, both ends of which are provided with bent portions 31. The tops of the two adjusting brackets 2 are provided with multiple locking slots 32 corresponding to the two bent portions 31. The tops of the two mounting brackets 1 are provided with multiple locking slots 32, and the two mounting brackets 1 can be connected to the locking slots 32 by locking rods 3.

[0026] It should be noted that the locking rod 3 is the core component of the locking mechanism, serving to lock and fix the enclosure 11. Two locking rods 3 connect two adjacent adjusting frames 2, and the engagement of the bent portion 31 with the locking groove 32 achieves fixation after angle adjustment of the enclosure 11. After the enclosure 11 is adjusted to the desired angle, the locking rod 3 is inserted into the corresponding locking groove 32, thereby restricting the rotation of the enclosure 11, maintaining the stability of the cofferdam structure, and preventing changes in the angle of the enclosure 11 due to external forces such as water flow impact during use, ensuring the reliable water-blocking function of the cofferdam. The bent portion 31 is designed for better engagement with the locking groove 32. By setting multiple locking grooves 32 on the adjusting frame 2 and the mounting bracket 1, the appropriate locking groove 32 can be selected to insert the locking rod 3 according to different adjustment angles of the enclosure 11, thus achieving fixation of the enclosure 11 at different angles. This design allows the locking mechanism to adapt to the needs of various angle adjustments of the enclosure 11, increasing the flexibility and applicability of the cofferdam structure. Meanwhile, the cooperation between the locking groove 32 and the bending part 31 can effectively restrict the movement of the locking rod 3 and ensure the reliability of the lock.

[0027] The working principle of the foldable and portable temporary cofferdam for water conservancy projects provided by this utility model is as follows: First, two mounting brackets 1 are transported to the construction site of the water conservancy project and placed in predetermined positions as the support points at both ends of the cofferdam. Then, multiple barriers 11 are sequentially connected between the two mounting brackets 1, with adjacent barriers 11 connected by rotating parts. When it is necessary to adjust the shape of the cofferdam according to the terrain of the construction area, the operator can rotate the barriers 11 to make the adjusting frame 2 rotate around the rotating shaft 22. The adjusting shaft 21 ensures that the barriers 11 can rotate flexibly, while the guide block 24 slides in the guide groove 25, providing guidance and limiting for the rotation of the adjusting frame 2, ensuring that the angle adjustment between the barriers 11 is accurate and stable. After the cofferdam 11 is adjusted to a suitable angle so that its shape conforms to the boundary of the construction area, the bent part 31 of the locking rod 3 is inserted into the corresponding locking groove 32 at the top of the adjusting frame 2 and the mounting bracket 1. Through the interlocking action of the locking rod 3 and the locking groove 32, the angle-adjusted cofferdam 11 is firmly fixed, preventing it from rotating under the action of external forces such as water flow impact, ensuring the stability of the cofferdam structure, and forming an effective water barrier. When the water conservancy project is completed and the cofferdam needs to be moved or stored, the locking rod 3 is first pulled out of the locking groove 32 to release the lock on the cofferdam 11. Then, the cofferdam 11 is folded around the rotating part to reduce the overall volume of the cofferdam, making it convenient for transportation and storage, and preparing it for the next use.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
