Description

Technical Field

[0001] The utility model relates to the field of gate water seals, in particular to a submerged arc gate water seal. Background Art

[0002] The selection and specific layout design of the waterstop type for high-head radial gates is a core issue in gate design. Poor design, poor manufacturing and installation quality control, and especially poor gluing of the gate water seal can cause water to leak through the gate gaps, leading to gate vibration and cavitation damage to embedded components. The higher the gate's design head, the greater the required waterstop rubber compression and the wider the required sealing surface. However, excessive water seal compression and an overly wide sealing surface not only increase the friction of the water seal and the capacity of the gate hoist, but also easily wear the water seal itself, causing it to fail and leak, potentially damaging the gate and gate slot embedded components. Therefore, simply increasing water seal compression and widening the sealing surface are insufficient to resolve the sealing issue.

[0003] The higher the gate head, the more difficult it is to stop water flow and the greater the likelihood of leakage. Furthermore, as the gate head increases, tighter water sealing is required to prevent the water seal from failing and damaging, ensuring safe gate operation. Currently, most water seals have spliced ​​corners, with the top and side water seals overlapped or cold-glued together using rubber blocks. This connection is weak and prone to tearing and leakage during gate raising and lowering. Furthermore, the overlapping or cold-glued connections between different water seals are prone to leakage. Utility Model Content

[0004] The purpose of the utility model is to address the defects of the existing technology and provide a submerged arc gate water seal, which adopts an integrated corner water seal to connect the side water seal and the top water seal, and performs good sealing at the corner position. It has high lightness and the integrated corner water seal can resist the pulling effect of the corner position, reduce the water leakage caused by the cracking of multiple parts at the corner position, and improve its sealing performance.

[0005] In order to achieve the above objectives, the following technical solutions are adopted:

[0007] The corner water seal includes an integrally formed side docking part, a corner part and a top docking part. The side docking part is connected to the side water seal and is arranged along the distribution direction of the side water seal. The top docking part is connected to the top water seal and is arranged along the distribution direction of the top water seal. One side of the corner part extends to the side docking part, and one end of the top docking part extends to the end face of the corner part. A through hole is provided on the corner part to cooperate with the fastener.

[0008] Furthermore, a plurality of through holes are provided on the side docking portion and are sequentially spaced along the distribution direction of the side water seal. The through holes cooperate with fasteners to connect the side docking portion to the side water seal.

[0010] Furthermore, the cross-section of the side docking portion is L-shaped.

[0011] Furthermore, a plurality of through holes are provided on the top docking portion and are sequentially spaced along the distribution direction of the top water seal. The through holes cooperate with fasteners to connect the top docking portion to the top water seal.

[0012] Furthermore, one end of the top butt joint away from the corner portion is glued to the top water seal.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0029] In traditional water seal structures, the corners are usually made up of multiple components, which are prone to cracking due to weak bonding or long-term tension, leading to water leakage. In addition, when the structure of multiple components is subjected to water pressure and the pulling effect of the gate opening and closing, it is easy to be damaged due to gaps between components or loose connections. Figure 1-Figure 7 As shown, this embodiment provides a submerged arc gate water seal, which realizes continuous sealing at the corner position through the integrated corner water seal, reduces the risk of water leakage, and the one-piece corner water seal can withstand greater pulling force, thereby improving the overall strength and stability of the structure.

[0030] In addition, the number of interfaces and connection points between components is reduced, the installation process is simplified, and maintenance costs are reduced; through-holes and fasteners are established to achieve connections between various water seal parts, which enhances the sealing and strength of the water seal and improves the overall performance and reliability of the submerged hole radial gate.

[0031] like Figure 1As shown, the submerged-hole radial gate water seal consists of four key components: side water seals, a bottom water seal 6, a top water seal 5, and corner water seals. The bottom water seal 6 is connected to a side water seal at each end, while the top water seal 5 is connected to the side water seal's end away from the bottom water seal 6 via corner water seals, forming a frame-shaped water seal structure. The bottom water seal 6 is located at the bottom of the structure, with both ends connected to the side water seals. The side water seals extend along both sides of the gate, connecting to the bottom water seal 6 at one end and to the top water seal 5 via corner water seals at the other end. The two side water seals are the first side water seal 3 and the second side water seal 4. The top water seal 5 is located at the top of the structure, with both ends connected to the side water seals via corner water seals. The corner water seals are key components connecting the side water seals and the top water seal 5, responsible for providing a good seal at the corners. The two corner water seals are the first corner water seal 1 and the second corner water seal 2. The first corner water seal 1 is connected to the first side water seal 3, and the second corner water seal 2 is connected to the second side water seal 4.

[0032] The corner water seal is made of one piece. Figure 2 、 Figure 3 As shown, the corner water seal is integrally formed from side butt joints 8, corner joints 9, and top butt joints 7, reducing the number of inter-component interfaces and improving overall strength and sealing. Side butt joints 8 are connected to the side water seals and arranged along the distribution direction of the side water seals. Corner joints 9 connect the side butt joints 8 and top butt joints 7, forming a smooth corner transition and featuring through-holes for fasteners. Top butt joints 7 are connected to the top water seal 5 and arranged along its distribution direction.

[0033] In the use scenario of a submerged radial gate, the gate needs to be stably mounted on the door frame or bracket to ensure that it can be opened and closed normally while maintaining good sealing performance. The corner portion 9 connects the side docking portion 8 and the top docking portion 7 and is provided with a through hole to accommodate fasteners. The through hole on the corner portion 9 is mainly used for connecting to the external door frame, gate bracket or other fixed structure.

[0034] Corner portion 9 is provided with a groove, and the through-holes are located within the groove, with the axes of the through-holes parallel to the distribution direction of the top docking portion 7. The grooves are located at the end of corner portion 9 away from the top docking portion 7. The multiple through-holes on corner portion 9 are arranged in a rectangular array. This rectangular array of through-holes ensures a more uniform and stable connection between corner portion 9, side docking portion 8, and top docking portion 7. This arrangement also facilitates the installation and removal of fasteners, improving maintenance convenience.

[0035] The groove helps reduce stress concentration at the corner portion 9 and improves the strength and durability of the corner portion 9. At the same time, the through hole in the groove facilitates the installation and fixation of fasteners, and the through hole axis is parallel to the distribution direction of the top docking portion 7, which is conducive to maintaining the stability and sealing of the corner portion 9.

[0036] Through the through holes and fasteners on the corner portion 9, the corner water seal can be integrated with the door frame, bracket and other structures, thereby enhancing the stability and strength of the entire gate structure.

[0037] The integrated corner water seal creates a continuous sealing surface at the corner, reducing the risk of water leakage caused by bonding multiple components. The integrated corner water seal can resist the pulling effect at the corner, improving the overall strength and stability of the structure.

[0038] In the traditional connection method, welding or simple mechanical connection is used to connect the top water seal 5 and the side water seal, which has the problem of loose connection, easy loosening or damage. Figure 4 As shown, the length of the docking portion is no less than 750 mm. Multiple through-holes are provided on the side docking portion 8, spaced sequentially along the distribution direction of the side water seal. Fasteners (such as bolts and nuts) securely connect the side docking portion 8 to the side water seal. The combination of through-holes and fasteners ensures a reliable connection between the side docking portion 8 and the side water seal, improving the overall strength and stability of the structure.

[0039] like Figure 1 As shown, the end of the side butt joint 8, away from the corner portion 9, is glued to the side water seal. Relying solely on mechanical connections cannot fully guarantee sealing, especially under long-term water pressure and gate opening and closing. Therefore, in this embodiment, gluing is used to enhance the sealing between the side butt joint 8 and the side water seal, reducing the risk of water leakage.

[0040] The cross section of the side docking portion 8 is designed to be L-shaped. Figure 4 and Figure 5 As shown, the side L-shaped section increases the contact area between the side butt joint 8 and the side water seal, thereby improving the stability and sealing of the connection. At the same time, the L-shaped section also facilitates the installation and fixing of fasteners.

[0041] It is understandable that the cross section of the side butt joint 8 adopts the P60B water seal recommended in the "Design Specifications for Steel Gates of Hydropower Projects", and other forms of side water seals, such as P45B water seals, etc., can also be used. Figure 5 shown.

[0042] Similar to the side docking portion 8, Figure 6 and Figure 7 As shown, the top butt joint 7 is no less than 750 mm long and is provided with a plurality of through-holes, which are sequentially spaced along the distribution direction of the top water seal 5. Fasteners securely connect the top butt joint 7 to the top water seal 5, thus achieving a reliable connection between the top butt joint 7 and the top water seal 5, and improving the overall strength and stability of the structure.

[0043] The end of the top butt joint 7 away from the corner portion 9 is also glued to the top water seal 5. A first seam 10 is formed between the top water seal 5 and the top butt joint 7 of the first corner water seal 1. The gluing at first seam 10 creates a second seam 11 between the top water seal 5 and the top butt joint 7 of the second corner water seal 2. This second seam 11 is also glued, enhancing the seal between the top butt joint 7 and the top water seal 5 and reducing the risk of water leakage.

[0044] like Figure 6 and Figure 7 As shown, the cross-section of the top abutment portion 7 is designed to be P-shaped. This P-shaped cross-section increases the contact area and sealing performance between the top abutment portion 7 and the top water seal 5, while also facilitating the installation and securing of fasteners. Furthermore, the P-shaped cross-section offers a certain degree of elasticity, better accommodating minor deformations of the top water seal 5 under load.

[0045] It is understandable that the cross section of the top butt joint 7 adopts the P60A water seal recommended in the "Design Specifications for Steel Gates of Hydropower Projects", and other forms of side water seals, such as P45A water seals, etc., can also be used. Figure 7 shown.

[0046] In summary, in response to the problems existing in the existing submerged radial gate water seal in terms of connection strength, sealing, stability and maintenance convenience, the performance of the submerged radial gate water seal is optimized and improved by adopting more advanced and reasonable structures and components.

[0047] like Figure 1 As shown, the connection position of the first side water seal 3 and the bottom water seal 6 forms a third seam 12, which is connected by gluing. The connection position of the second side water seal 4 and the bottom water seal 6 forms a fourth seam 13, which is connected by gluing. This enhances the sealing between the side water seal and the bottom water seal 6 and reduces the risk of water leakage.

[0048] The above detailed description of the specific embodiments of the utility model is intended to be illustrative only, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions made to the utility model are also within the scope of the utility model. Therefore, equivalent changes, modifications, and improvements made without departing from the spirit and scope of the principles of the utility model should be included within the scope of the utility model.
