Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a sealing structure for a spliced ​​drainage ditch. Background Technology

[0002] Traditional interlocking drainage ditch seals are mostly flat, solid rubber sheets. The solid structure has a low compressibility, requiring numerous bolts to compress and deform the sheet during assembly to generate sufficient sealing force. Excessive bolts lead to low installation efficiency and increased labor and material costs. The limited thickness of the flat sheet results in a small compression space, making it prone to leaks when the drainage ditch vibrates or the medium pressure fluctuates. Furthermore, the sheet is located on the visible surface of the drainage ditch joints, affecting the overall aesthetics. The root cause lies in the structural and elastic defects of existing sealing sheets, which prevent them from providing a reliable seal with a small number of bolts and result in poor aesthetic integration. These problems urgently need to be addressed in the development and application of drainage ditch technology. Utility Model Content

[0003] The purpose of this invention is to provide a sealing structure for a spliced ​​drainage ditch that can overcome the shortcomings of existing sealing film structures and elasticity.

[0004] To achieve the above objectives, a sealing structure for a modular drainage ditch is provided, comprising a modular drainage ditch body, wherein both ends of the modular drainage ditch body are fixedly connected to a ditch body flange, and a sealing flange is fixedly connected to the outer wall of the modular drainage ditch body and the ditch body flange.

[0005] Each of the sealing flanges has a ring of fixing holes inside, and each fixing hole has a fixing bolt inside. Each sealing flange is fixed to the adjacent sealing flange by the fixing bolt, and a sealing strip is provided between the fixing bolt and the groove flange.

[0006] According to the sealing structure of the spliced ​​drainage ditch, the main body of the spliced ​​drainage ditch and the ditch body protrusion are made of integral molding technology, which improves the connection strength between the main body of the spliced ​​drainage ditch and the ditch body protrusion.

[0007] According to the aforementioned sealing structure of a spliced ​​drainage ditch, the sealing strip is set as a hollow cylinder and is made of elastic rubber material. The hollow sealing strip can improve the compression rate. After the two sections of the ditch are locked with bolts, the strip is flattened, resulting in better elasticity. It can achieve good sealing performance without the need for too many bolts, thus improving the installation efficiency of the device.

[0008] According to the sealing structure of the spliced ​​drainage ditch, one end of each fixing bolt is threaded with a fixing nut, and the two sealing flanges can be fixed by the fixing bolt and the fixing nut.

[0009] According to the sealing structure of the spliced ​​drainage ditch, the distribution density and specifications of the fixing holes are configured according to the size and pressure requirements of the spliced ​​drainage ditch body to improve the uniformity of the fixing pressure.

[0010] According to the sealing structure of the spliced ​​drainage ditch, the main body of the spliced ​​drainage ditch is one of a straight section of water ditch, a curved water ditch, an irregular water ditch, or a water ditch connector. The sealing structure is applicable to various types of spliced ​​drainage ditches and can maintain a good sealing effect at the splicing points of different types of water ditches.

[0011] According to the aforementioned sealing structure of a spliced ​​drainage ditch, the size of the sealing strip is adapted to the joint size of the drainage ditch to ensure the sealing effect, and the length of the sealing strip is matched with the length of the convex edge of the ditch body, so that the sealing strip can align with the convex edge of the ditch body.

[0012] According to the sealing structure of the spliced ​​drainage ditch, the sealing flange is perpendicular to the main body of the spliced ​​drainage ditch, which improves the fit between the main body of the spliced ​​drainage ditch and the adjacent spliced ​​drainage ditch bodies.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, this utility model uses a hollow cylindrical elastic rubber sealing strip, whose compression ratio is much higher than that of traditional flat solid rubber sheets. When the two drainage channels are tightened with bolts, the hollow sealing strip is compressed and deformed, generating a strong elastic sealing force. This effectively overcomes the problems of poor sealing and easy leakage caused by the low compression ratio of rubber sheets in existing technologies, significantly improving sealing performance. At the same time, due to the high elasticity of the hollow sealing strip, a good seal can be achieved without using a large number of bolts, greatly reducing the number of bolts used compared to traditional methods, lowering labor and time costs during installation, and significantly improving installation efficiency.

[0015] 2. After the drainage ditch is assembled, the joints are seamless, and the sealing strip is hidden between the ditch's raised edge and the bolts, making it invisible. This avoids the problem of exposed sealing strips affecting the overall aesthetics of the drainage ditch, as seen in existing technologies, thus enhancing its visual appeal and decorative quality. Furthermore, the seamless joints reduce water flow resistance during drainage, resulting in smoother drainage compared to traditional drainage ditches. This reduces the risk of blockages caused by poor drainage and improves the reliability and stability of the drainage system.

[0016] 3. The hollow rubber strip flange structure of this utility model has strong versatility and adaptability. It is not only suitable for splicing straight sections of drainage ditches, but also applicable to various types of drainage ditch scenarios such as curved ditches, irregular ditches, and ditch connectors. Compared with some existing sealing structures that are only suitable for drainage ditches of specific shapes, this utility model can maintain a good sealing effect in the splicing of drainage ditches of different types and complex shapes, greatly expanding its application range and meeting diverse drainage engineering needs.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides a sealing structure for a spliced ​​drainage ditch, which includes a spliced ​​drainage ditch body 1. Both ends of the spliced ​​drainage ditch body 1 are fixedly connected to a ditch body protrusion 101. The spliced ​​drainage ditch body 1 and the ditch body protrusion 101 are made using an integral molding technology, thereby improving the connection strength between the spliced ​​drainage ditch body 1 and the ditch body protrusion 101.

[0026] The main body 1 of the modular drainage ditch is fixedly connected to the outer wall of the ditch body protrusion 101 with a sealing flange 2. Each sealing flange 2 has a ring of fixing holes 201 inside. The distribution density and specifications of the fixing holes 201 are configured according to the size and pressure requirements of the main body 1 of the modular drainage ditch to improve the uniformity of the fixing pressure.

[0027] Each fixing hole 201 is equipped with a fixing bolt 4 inside, and one end of each fixing bolt 4 is threaded with a fixing nut 401. The two sealing flanges 2 can be fixed by fixing bolts 4 and fixing nuts 401.

[0028] Each sealing flange 2 is fixed to the adjacent sealing flange 2 by fixing bolts 4. A sealing strip 3 is provided between the fixing bolts 4 and the groove body flange 101. The sealing strip 3 is set as a hollow cylinder and is made of elastic rubber material. The hollow sealing strip 3 can improve the compression ratio. After the two sections of the water ditch are locked with bolts, the strip is flattened, which improves the elasticity. It can achieve good sealing without locking too many bolts, thus improving the installation efficiency of the device. The size of the sealing strip 3 is adapted to the joint size of the drainage ditch to ensure the sealing effect. The length of the sealing strip 3 matches the length of the groove body flange 101, so that the sealing strip 3 can fit the groove body flange 101.

[0029] The main body 1 of the spliced ​​drainage ditch is one of the following: straight section of water ditch, curved water ditch, irregular water ditch, or water ditch connector. The sealing structure is suitable for various types of spliced ​​drainage ditches and can maintain a good sealing effect at the splicing points of different types of water ditches. The sealing flange 2 is perpendicular to the main body 1 of the spliced ​​drainage ditch, which improves the fit between the main body 1 of the spliced ​​drainage ditch and the adjacent main body 1 of the spliced ​​drainage ditch.

[0030] Unless otherwise specified, the constituent units of this utility model are obtained from conventional commercial channels or manufactured by conventional methods. Their specific structure, working principle, and possible control methods and spatial arrangement methods can adopt conventional choices in the field and should not be regarded as the innovation of this utility model. This is understandable to those skilled in the art, and this utility model patent will not be further elaborated in detail.

[0031] Working Principle: When using the sealing structure of the spliced ​​drainage ditch of this utility model, first align the ends of the two sections of the spliced ​​drainage ditch body 1. The ditch body protrusions 101 at both ends of the spliced ​​drainage ditch body 1 and the sealing flanges 2 together form the basic frame of the sealing structure. Next, align the hollow cylindrical sealing strip 3 with the outer wall of the ditch body protrusion 101, and then align the fixing bolts 4 with the fixing holes 201 on the sealing flanges 2. When the fixing bolts 4 pass through the fixing holes 201 and the fixing nuts 401 are tightened, the sealing strip 3 is compressed between the ditch body protrusion 101 and the fixing bolts 4. Since the sealing strip 3 is made of elastic rubber material, its hollow structure will generate a strong elastic deformation force after being compressed, thereby tightly filling the tiny gaps between the drainage ditch joints, forming a reliable sealing barrier, and effectively preventing water leakage from the joints. During drainage, water flows along the main body 1 of the drainage ditch. When the water passes the joint, the sealing strip 3 prevents water from seeping out, ensuring smooth drainage and a tight system seal. Simultaneously, the mating structure between the ditch body flange 101 and the sealing flange 2 provides a limiting effect for the sealing strip 3, preventing displacement or deformation when the drainage ditch vibrates or is impacted by water flow, thus ensuring the stability of the seal. The splicing principle is the same for different types of drainage ditches, such as straight sections, curved sections, irregular sections, or ditch connectors; all can achieve a good sealing effect through this sealing structure, meeting the needs of various drainage scenarios.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
