Description

Technical Field

[0001] This utility model relates to the field of anti-seepage and water-stopping structure technology, specifically to an anti-seepage and water-stopping structure for hydraulic buildings. Background Technology

[0002] Hydraulic engineering structures are engineering facilities built around the development, utilization, control, and protection of water resources. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed. Hydraulic engineering projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals. In the construction of hydraulic engineering projects, water pipes need to be seeped and sealed to prevent water leakage during use.

[0003] Utility model patent CN214947247U discloses a seepage-proof and water-stopping structure for hydraulic structures, including a pipe body. A water-stop sealing gasket is fixedly connected to the inner wall of the pipe body. Multiple guide plates are symmetrically fixedly connected to the inner wall of the water-stop sealing gasket. Two connecting plates are symmetrically fixedly connected to the inner wall of the water-stop sealing gasket. A rotating rod is rotatably connected to the side walls of the two connecting plates. A rotating plate is fixedly sleeved on the rod wall. An arc-shaped diverting plate is fixedly connected to the top of the rotating plate. This utility model, through the design of the guide plates and arc-shaped diverting plate, allows the multiple guide plates to initially reduce the kinetic energy of the water entering the pipe. The water also experiences secondary energy reduction after passing through the arc-shaped diverting plate, reducing the impact force between the water flow and the inner wall of the pipe. This not only improves the service life of the pipe but also prevents pipe rupture and seepage.

[0004] While existing water-stopping structures for hydraulic structures prevent water seepage caused by pipe rupture by reducing the impact of water flow on the inner wall of the pipe, in practical applications, impurities such as silt carried by the water flow will accumulate at the bottom of the pipe because the water-stopping structure is directly installed on the bottom wall of the pipe. This accumulation will not only cause the water-stopping structure to gradually lose its original buffering performance, but may also cause pipe blockage, thus seriously affecting the water-stopping effect of the hydraulic structure. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a seepage prevention and water-stopping structure for hydraulic structures, which can effectively solve the problem that impurities such as silt carried by water flow tend to accumulate at the bottom of the seepage prevention and water-stopping structure, resulting in reduced buffering performance, pipe blockage, and thus affecting the seepage prevention and water-stopping effect of hydraulic structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a water-proof and waterproof structure for hydraulic structures, including: a connecting bend and a connecting structure. The two ends of the connecting bend are fixedly connected to the connecting structure. A support and buffer assembly is fixedly connected to the inner wall of the connecting bend. The support and buffer assembly includes several sets of elastic plates. An elastic connecting strip is fixedly connected to the inner side of the elastic plate. An inclined plate is fixedly connected to the inner side of the elastic connecting strip. A flow groove is opened on the inner side of the inclined plate.

[0008] The inner wall of the connecting bend is equipped with a flow guiding and buffering assembly, which includes a flow guiding plate. A flow guiding support plate is installed on the bottom surface inside the connecting bend. A buffer plate is fixedly connected to the top of the flow guiding support plate. A hydrophobic layer is fixedly connected to the top of the buffer plate.

[0009] Furthermore, a reinforcing rod is fixedly connected inside the elastic connecting strip. The reinforcing rod is rotatably connected to the inclined plate. Two sets of connecting rods are fixedly connected to the side of the reinforcing rod away from the inclined plate. A fixing plate is installed at the other end of the connecting rod. The fixing plate is fixedly connected to the inner wall of the connecting bend.

[0010] Furthermore, the inner wall of the buffer plate has a cavity, and a buffer column is fixedly connected to the bottom surface inside the cavity, and the top of the buffer column is fixedly connected to the top surface inside the cavity.

[0011] Furthermore, a sealing layer is fixedly connected inside the connecting bend, and a wear-resistant layer is fixedly connected to the inner side of the elastic plate.

[0012] Furthermore, a spiral guide vane is fixedly connected inside the flow channel, and a buffer pad is installed on the top of the inclined plate.

[0015] Furthermore, a sponge block is fixedly connected inside the cavity, and a connecting groove is formed on the top of the sponge block, with the buffer column located inside the connecting groove.

[0016] Beneficial effects

[0019] II. This utility model, by setting components such as a flow guide support plate, a hydrophobic layer, a buffer pad, and a flow guide channel, and by using the inclined structure of the flow guide support plate and the buffer plate in conjunction with the smooth surface of the hydrophobic layer, allows water to flow quickly through the flow guide channel.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] See attached document Figure 1-4 A water-stopping and seepage-proof structure for hydraulic structures includes: a connecting bend 1 and a connecting structure 2. Both ends of the connecting bend 1 are fixedly connected to the connecting structure 2. A support and buffer assembly 3 is fixedly connected to the inner wall of the connecting bend 1. The support and buffer assembly 3 includes several sets of elastic plates 31. An elastic connecting strip 32 is fixedly connected to the inner side of each elastic plate 31. An inclined plate 33 is fixedly connected to the inner side of each elastic connecting strip 32. A flow groove 34 is formed on the inner side of the inclined plate 33. A flow-guiding and buffer assembly 4 is installed on the inner wall of the connecting bend 1. The flow-guiding and buffer assembly 4 includes a flow-guiding plate 41. A flow guide support plate 42 is installed on the bottom surface inside the connecting bend 1. A buffer plate 43 is fixedly connected to the top of the flow guide support plate 42. A hydrophobic layer 44 is fixedly connected to the top of the buffer plate 43. The elastic plate 31, elastic connecting strip 32, inclined plate 33 and flow channel 34 in the support buffer assembly 3 can buffer the impact force of water flow. The flow guide plate 41, flow guide support plate 42, buffer plate 43 and hydrophobic layer 44 in the flow guide buffer assembly 4 can guide water flow and enhance seepage prevention performance, realize the buffering, flow guidance and seepage prevention of water flow, and reduce the accumulation of silt.

[0030] A reinforcing rod 5 is fixedly connected inside the elastic connecting strip 32. The reinforcing rod 5 is rotatably connected to the inclined plate 33. Two sets of connecting rods 6 are fixedly connected to the side of the reinforcing rod 5 away from the inclined plate 33. A fixing plate 7 is installed at the other end of the connecting rod 6. The fixing plate 7 is fixedly connected to the inner wall of the connecting bend 1. The reinforcing rod 5 inside the elastic connecting strip 32 is rotatably connected to the inclined plate 33. The reinforcing rod 5 is fixed to the inner wall of the connecting bend 1 through the connecting rod 6 and the fixing plate 7, which enhances the stability of the fixed buffer. A cavity 8 is opened in the inner wall of the buffer plate 43. A buffer column 9 is fixedly connected to the bottom surface of the cavity 8. The top of the buffer column 9 is fixedly connected to the top surface of the cavity 8. A buffer column 9 is set in the cavity 8 of the inner wall of the buffer plate 43. The buffer column 9 is connected to the bottom of the cavity 8. The top and bottom surfaces provide buffering force when water flows. A sealing layer 10 is fixedly connected inside the connecting bend 1, and a wear-resistant layer 11 is fixedly connected inside the elastic plate 31. The sealing layer 10 inside the connecting bend 1 improves the overall sealing performance and prevents water leakage. The wear-resistant layer 11 inside the elastic plate 31 enhances wear resistance and extends the service life of the components, avoiding the situation where the elastic plate 31 fails and is damaged, resulting in poor buffering effect of the inclined plate 33. A spiral guide vane 12 is fixedly connected inside the flow channel 34, and a buffer pad 13 is installed on the top of the inclined plate 33. The spiral guide vane 12 in the flow channel 34 guides the water flow in a spiral, reducing water flow resistance. The buffer pad 13 on the top of the inclined plate 33 further buffers the water flow impact force and improves the buffering effect.

[0031] A flow guide groove 14 is provided on the top of the buffer pad 13. A sealing strip 15 is fixedly connected to the top edge of the flow guide support plate 42. The sealing strip 15 is fixedly connected to the outer side of the buffer plate 43 and the inner wall of the connecting bend 1. The flow guide groove 14 on the top of the buffer pad 13 guides the water flow. The sealing strip 15 on the top edge of the flow guide support plate 42 connects the buffer plate 43 and the inner wall of the connecting bend 1, enhancing the sealing of the connection and preventing water leakage. Several sets of reinforcing blocks are installed at the bottom of the reinforcing rod 5. 16. The reinforcing block 16 is fixedly connected to the fixing plate 7. The reinforcing block 16 at the bottom of the reinforcing rod 5 is fixedly connected to the fixing plate 7, which further reinforces the reinforcing rod 5 and ensures the stability of the support. A sponge block 17 is fixedly connected inside the cavity 8. A connecting groove 18 is opened on the top of the sponge block 17. The buffer column 9 is located inside the connecting groove 18. The sponge block 17 in the cavity 8 absorbs the impact energy. The connecting groove 18 on the top of the sponge block 17 accommodates the buffer column 9. The two work together to improve the buffering effect of the buffer plate 43.

[0032] Working principle: When water flows into the connecting bend 1, it first impacts the inclined plate 33. The inclined plate 33 absorbs the impact force of the water flow through the elastic deformation of the elastic plate 31 and the elastic connecting strip 32. At the same time, the flow groove 34 on the inner side of the inclined plate 33, together with the spiral guide plate 12, guides the water flow in a spiral shape, thereby reducing the direct impact force of the water flow. The elastic plate 31 buffers the impact of the water flow on the wall of the connecting bend 1. During this process, the reinforcing rod 5 is fixed to the inner wall of the connecting bend 1 through the connecting rod 6 and the fixing plate 7. The reinforcing block 16 further enhances the stability, so that the inclined plate 33 remains stable during the buffering process, thereby effectively reducing the impact of the water flow on the connecting bend 1 and preventing the pipe from rupturing and leaking due to impact.

[0033] Next, the guide plate 41 initially guides the water flow, while the inclined structure of the guide support plate 42 and the buffer plate 43, combined with the smooth surface of the hydrophobic layer 44, allows the water flow to be quickly guided through the guide channel 14 on the top of the buffer pad 13. The buffer column 9 and the sponge block 17 in the cavity 8 of the inner wall of the buffer plate 43 work together to provide buffering force and absorb energy when the water flow impacts, further reducing the impact of the water flow. This guide design makes it difficult for impurities such as mud and sand carried by the water flow to accumulate at the bottom of the pipe, avoiding the problems of decreased buffering performance and pipe blockage, and ensuring the seepage prevention and water-stopping effect of the hydraulic structure.

[0034] In addition, the sealing layer 10 inside the connecting bend 1, the sealing strip 15 at the top edge of the flow guide support plate 42, and the wear-resistant layer 11 on the inner side of the elastic plate 31 work together to form a multi-layer sealing system with the sealing layer 10 and the sealing strip 15 to prevent water leakage. The wear-resistant layer 11 enhances the wear resistance of the elastic plate 31 and extends the service life of the components. The sponge block 17 absorbs impact energy and works with the buffer column 9 to improve the buffering effect, ensuring the long-term stable operation of the entire seepage prevention and water-stopping structure, thereby effectively improving the reliability of seepage prevention and water-stopping in hydraulic structures.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
