[0002] In water conservancy projects, pipeline connection is a crucial link in the water conveyance system. Existing technologies offer various pipeline connection methods, such as welding, flange connections, and socket connections. However, these methods have certain drawbacks in practical applications: while welding offers high strength, the construction process is complex and subsequent maintenance is inconvenient; although flange connections offer high connection strength and convenient maintenance, during long-term use, factors such as water flow impact and pipeline vibration can cause bolts to loosen, leading to a decrease in the sealing performance of the connection; for large-diameter pipelines or high-pressure conditions, socket connections lack sufficient stability and are prone to disengagement. With the continuous expansion of water conservancy projects, higher requirements are placed on the stability, sealing, and construction convenience of pipeline connections. Therefore, the development of a new type of pipeline connection reinforcement structure for water conservancy projects has important practical significance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 The present invention provides the following technical solution: a reinforcement structure for connecting water conservancy engineering pipelines, including a reinforcement structure body 2 for reinforcing the connecting flange 11 of two pipeline bodies 1. The reinforcement structure body 2 includes: two combinable reinforcement parts, fastening components and sealing components.

[0021] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, two reinforcing members enclose a circular positioning space for accommodating the connecting flange 11. A fastening assembly is used to fix the reinforcing member to the connecting flange 11. A sealing assembly is disposed between the reinforcing member and the connecting flange 11, and between the connecting flanges 11 of the two pipe bodies 1. The reinforcing member includes a reinforcing base 21 and a semi-circular reinforcing plate 22. The top surface of the reinforcing base 21 has a lower positioning groove 211 for the lower half of the connecting flange 11 to be embedded in. The semi-circular reinforcing plate 22 has an upper positioning groove 221 for the upper half of the connecting flange 11 to be embedded in. Both ends of the reinforcing base 21 are connected to both ends of the semi-circular reinforcing plate 22 via fastening assemblies. The fastening assembly includes two threaded posts 212, two fixing blocks 222, and a locking nut 23. The two threaded posts 212 are symmetrically fixed to the top surface of the reinforcing base 21, and the two fixing blocks 222 are symmetrically fixed to both ends of the semi-circular reinforcing plate 22. The fixing blocks 222 are provided with notches 2221 for the threaded posts 212 to pass through. The locking nut 23 is provided at the protruding end of the threaded post 212 by threaded engagement. After adopting the above scheme, when using it, the initial docking of the two pipe bodies 1 must be completed first, so that their connecting flanges 11 are aligned and fitted. At this time, the sealing assembly has been pre-placed between the two connecting flanges 11 to prepare the foundation for subsequent sealing.

[0022] Next, the reinforcement structure body 2 is installed. First, the reinforcement seat 21 of the two reinforcement parts is placed below the connecting flange 11, so that the lower half of the connecting flange 11 is embedded in the lower positioning groove 211 on the top surface of the reinforcement seat 21. The lower positioning groove 211 can play a preliminary positioning and support role for the connecting flange 11, preventing it from shifting during the installation process.

[0023] Subsequently, the semi-circular reinforcing plate 22 is fastened onto the upper part of the connecting flange 11, so that the upper part of the connecting flange 11 is embedded in the upper positioning groove 221 on the inner side of the semi-circular reinforcing plate 22. The upper positioning groove 221 and the lower positioning groove 211 cooperate with each other to further restrict the position of the connecting flange 11 and ensure that it is in the correct enclosure space. When the semi-circular reinforcing plate 22 is fastened, the threaded posts 212 at both ends of the reinforcing seat 21 will pass through the notches 2221 on the fixing blocks 222 at both ends of the semi-circular reinforcing plate 22.

[0024] Subsequently, the reinforcement components are fixed by fastening the fastening components. The locking nut 23 is screwed onto the protruding end of the threaded post 212. As the locking nut 23 is tightened, it will drive the semi-circular reinforcement plate 22 to move downward. Together with the reinforcement seat 21, it will apply a clamping force to the connecting flange 11, so that the two reinforcement components are tightly spliced ​​together and form a stable circular positioning space, which firmly fixes the connecting flange 11 in it. This effectively enhances the overall strength and stability of the pipeline connection and prevents the pipeline connection from loosening due to factors such as water flow impact during the operation of the water conservancy project.

[0025] Meanwhile, the sealing components installed between the reinforcing member and the connecting flange 11, as well as between the two connecting flanges 11, will deform under the clamping force of the reinforcing member, tightly filling the gaps between the components, thereby achieving a good sealing effect, preventing water leakage, and ensuring the normal operation of the water conservancy project pipeline system.

[0026] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the sealing assembly includes a rubber sealing sleeve 24 and a rubber sealing ring 25. The rubber sealing sleeve 24 is fitted onto the connecting flange 11, and a groove 241 for the connecting flange 11 to be inserted is provided on the inner wall of the rubber sealing sleeve 24. The rubber sealing ring 25 is disposed between the connecting flanges 11 of the two pipe bodies 1.

[0027] After adopting the above solution, when using it, first put the rubber sealing sleeve 24 on the connecting flange 11 to ensure that the outer edge of the connecting flange 11 is accurately embedded in the groove 241 of the inner wall of the rubber sealing sleeve 24. The size of the groove 241 matches the connecting flange 11 and can firmly hold the connecting flange 11, so that the rubber sealing sleeve 24 and the connecting flange 11 fit tightly together, initially forming a sealing barrier to prevent moisture from seeping out from the gap between the connecting flange 11 and the reinforcement.

[0028] Next, before the connecting flanges 11 of the two pipe bodies 1 are aligned and fitted, the rubber sealing ring 25 is placed between the connecting flanges 11 of the two pipe bodies 1. When the two connecting flanges 11 are mated, the rubber sealing ring 25 is in the middle position.

[0029] As the locking nuts 23 of the fastening components in the reinforced structure body 2 are tightened, the reinforcing seat 21 and the semi-circular reinforcing plate 22 apply clamping force to the connecting flange 11. The connecting flange 11 will compress the rubber sealing ring 25. The rubber sealing ring 25 has good elasticity and deforms under the compression, tightly filling all the tiny gaps between the two connecting flanges 11, effectively preventing moisture from leaking from the joint of the two connecting flanges 11.

[0030] At the same time, the rubber sealing sleeve 24 will also be compressed under the clamping force of the reinforcement, making it fit more tightly with the connecting flange 11 and the inner wall of the reinforcement. The elasticity of the rubber sealing sleeve 24 allows it to adapt to the slight deformation of the reinforcement and connecting flange 11 after being subjected to force, maintaining a continuous sealing state and further enhancing the overall sealing effect. It works in conjunction with the rubber sealing ring 25 to form a double sealing guarantee, ensuring the tightness of the connection parts of the water conservancy project pipeline and preventing water leakage.

[0031] Preferably, by Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, this embodiment also includes: two first clamping plates 4, a first bolt 5, two second clamping plates 6, and a second bolt 7. The two first clamping plates 4 are symmetrically arranged in the lower positioning groove 211. The first bolt 5 is screwed onto the reinforcing seat 21 and corresponds to the first clamping plate 4. The two second clamping plates 6 are symmetrically arranged in the upper positioning groove 221. The second bolt 7 is screwed onto the semi-circular reinforcing plate 22 and corresponds to the second clamping plate 6. With the above scheme, in use, after the installation of the rubber sealing sleeve 24 and the rubber sealing ring 25 is completed, and the reinforcing seat 21 and the semi-circular reinforcing plate 22 are initially fastened to the connecting flange 11, the two first clamping plates 4, the first bolt 5, the two second clamping plates 6, and the second bolt 7 can be used for further reinforcement to accommodate connecting flanges 11 with different thicknesses.

[0032] For the first clamping plate 4 in the lower positioning groove 211, after the reinforcing seat 21 is placed and the lower half of the connecting flange 11 is embedded in the lower positioning groove 211, the operator can rotate the first bolt 5. Since the first bolt 5 is set on the reinforcing seat 21 by thread engagement and corresponds to the first clamping plate 4, as the first bolt 5 is tightened, its end will push the first clamping plate 4 closer to the connecting flange 11. The two symmetrically arranged first clamping plates 4 apply clamping force to the lower half of the connecting flange 11 from both sides, further enhancing the connection stability between the connecting flange 11 and the reinforcing seat 21 and preventing the connecting flange 11 from shaking in the reinforcing seat 21.

[0033] As for the second clamping plate 6 in the upper positioning groove 221, after the semi-circular reinforcing plate 22 is fastened in place, the second bolt 7 is rotated. The second bolt 7 is also set on the semi-circular reinforcing plate 22 and corresponds to the second clamping plate 6 by thread engagement. During the tightening process, the second bolt 7 will push the second clamping plate 6 to move towards the connecting flange 11. The two symmetrical second clamping plates 6 apply clamping force to the upper half of the connecting flange 11 from both sides, which cooperates with the force of the first clamping plate 4 to firmly fix the connecting flange 11 in the space enclosed by the reinforcing seat 21 and the semi-circular reinforcing plate 22 from the upper and lower parts.

[0034] Through the coordinated action of the first clamping plate 4, the first bolt 5, the second clamping plate 6, and the second bolt 7, the connection flange 11 can be finely adjusted according to its actual size, ensuring that the connection flange 11 is stably clamped. This greatly improves the adaptability of the reinforcement structure to connection flanges 11 of different specifications, while further strengthening the firmness of the pipeline connection and effectively resisting the impact of external forces such as water flow impact on the pipeline connection.

[0035] Preferably, by Figure 1 and Figure 3As shown, in this embodiment, it further includes: an adjustable support assembly 3, which is disposed at the bottom of the reinforcement base 21 to provide support for the reinforcement base 21. The adjustable support assembly 3 includes a support plate 31 and an adjustment mechanism disposed between the support plate 31 and the reinforcement base 21. The adjustment mechanism is used to adjust the height of the reinforcement base 21. The adjustment mechanism includes: two movable seats 32, two sets of flip support rods 33, two fixed plates 34, a bidirectional threaded screw 35, a knob 36 fixed to the end of the bidirectional threaded screw 35, and two guide rods 37. The two movable seats 32 are symmetrically distributed and movably connected to the support plate 31. The two sets of flip support rods 33 are symmetrically distributed and flip support rods 37. One end of rod 33 is hinged to reinforcing seat 21, and the other end is hinged to movable seat 32. Two fixed plates 34 are symmetrically fixed to the top surface of support plate 31. Two bidirectional threaded screws 35 are rotatably installed between the two fixed plates 34. Two movable seats 32 are respectively engaged with the two reverse threads of the bidirectional threaded screws 35. Two guide rods 37 are symmetrically fixed between the two support plates 31 and pass through the movable seats 32. With the above scheme, when using the adjustable support assembly 3, its core function is to form a stable support for the reinforcing seat 21 and flexibly adjust the height of the reinforcing seat 21 according to the actual installation environment and pipeline height requirements, thereby ensuring that the entire reinforcement structure is in the best working state.

[0036] First, the support plate 31, as the basic component of the adjustable support assembly 3, is in direct contact with the ground or other support surfaces, providing a stable bottom support for the entire assembly. When it is necessary to adjust the height of the reinforcing seat 21, the operator can do so by rotating the knob 36 fixed at the end of the bidirectional threaded rod 35.

[0037] The bidirectional threaded screw 35 is rotatably mounted between two fixed plates 34 symmetrically fixed to the top surface of the support plate 31, and the two movable seats 32 respectively engage with the two reverse threads of the bidirectional threaded screw 35.

[0038] Since the two guide rods 37 are symmetrically fixed between the two support plates 31 and pass through the movable seat 32, the guide rods 37 can restrict the rotation of the movable seat 32, so that it can only move along the axial direction of the guide rods 37. When the rotating knob 36 drives the bidirectional threaded screw 35 to rotate, the two movable seats 32 will move in a straight line along the guide rods 37 towards or away from each other under the action of the reverse thread.

[0039] When the two movable seats 32 approach each other, the two sets of flip support rods 33 hinged to the movable seats 32 will flip, and the position of their hinge points with the reinforcing seat 21 and the movable seat 32 will change, so that the included angle between the flip support rods 33 decreases, thereby lifting the reinforcing seat 21 upward and increasing the height of the reinforcing seat 21; conversely, when the two movable seats 32 move away from each other, the included angle between the flip support rods 33 increases, the reinforcing seat 21 descends, and the height decreases.

[0040] Through this adjustment process, the adjustable support assembly 3 can precisely adjust the height of the reinforcement seat 21 to ensure that the connecting flange 11 is in a horizontal or suitable position, thereby enhancing the stability and adaptability of the entire pipeline connection reinforcement structure and enabling it to work reliably under different terrain and installation conditions.

[0041] Components not described in detail in this article are existing technologies.

[0042] The working principle and usage process of this utility model: When using the reinforcement structure of this utility model, the first step is to prepare and connect with the foundation. Align the connecting flanges 11 of the two pipe bodies 1 and place a rubber sealing ring 25 between the mating surfaces. This is the key to ensuring the initial seal at the pipe connection. At the same time, put the rubber sealing sleeve 24 on the connecting flange 11 to ensure that the connecting flange 11 is accurately embedded in the groove 241 on the inner wall of the rubber sealing sleeve 24. With the limiting effect of the groove 241, the rubber sealing sleeve 24 and the connecting flange 11 are tightly fitted to form the first line of sealing defense and initially block the water leakage path. For large-diameter drainage pipes, due to the weight of the pipes and the high vibration during water transport, bolts and nuts can be used to pre-reinforce the two connecting flanges 11 after they are joined together. Next, the reinforcement components are installed and initially fixed. The reinforcement base 21 is placed below the connecting flange 11, so that the lower half of the connecting flange 11 is embedded in the lower positioning groove 211 on the top surface of the reinforcement base 21. The lower positioning groove 211 provides initial positioning and support for the connecting flange 11, preventing it from shifting in subsequent operations. Then, the semi-circular reinforcement plate 22 is fastened above the connecting flange 11, so that the upper half of the connecting flange 11 is embedded in the upper positioning groove 221 on the inner side of the semi-circular reinforcement plate 22. The upper positioning groove 221 and the lower positioning groove 211 cooperate to further restrict the position of the connecting flange 11. At this time, the threaded posts 212 at both ends of the reinforcement base 21 pass through the notches 2221 on the fixing blocks 222 at both ends of the semi-circular reinforcement plate 22. By tightening the locking nuts 23 at the protruding ends of the threaded posts 212, the semi-circular reinforcement plate 22 is moved downward, and together with the reinforcement base 21, it applies a clamping force to the connecting flange 11, so that the two reinforcement components are tightly spliced ​​together to form a stable circular positioning space, thus initially fixing the connecting flange 11. The fixing effect is then strengthened by the clamping plate and bolt assembly. For the two symmetrical first clamping plates 4 in the lower positioning groove 211, the corresponding first bolts 5 on the reinforcing seat 21 are rotated. The first bolts 5 push the first clamping plates 4 closer to the connecting flange 11, clamping the lower half of the connecting flange 11 from both sides. Similarly, the second bolts 7 on the semi-circular reinforcing plate 22 are rotated, pushing the two symmetrical second clamping plates 6 in the upper positioning groove 221 to clamp the upper half of the connecting flange 11. The first clamping plates 4 and the second clamping plates 6 work together to form an all-round clamping of the connecting flange 11 from the top and bottom. The clamping force is finely adjusted according to the actual size of the connecting flange 11, which significantly improves the connection stability between the connecting flange 11 and the reinforcing member and prevents the connecting flange 11 from shaking in the reinforcing space. Meanwhile, the sealing components enhance the sealing performance under the clamping force. The rubber sealing ring 25 undergoes elastic deformation under the compression of the two connecting flanges 11, tightly filling the tiny gaps between the mating surfaces and preventing moisture from leaking from the mating joint of the connecting flanges 11. The rubber sealing sleeve 24 is compressed under the clamping force of the reinforcement, making it fit more tightly with the connecting flanges 11 and the inner wall of the reinforcement. Its elastic properties can adapt to the tiny deformation of the components after being subjected to force, continuously maintaining the sealing state, forming a double sealing guarantee with the rubber sealing ring 25 to ensure the tightness of the pipeline connection. Finally, the adjustable support assembly 3 achieves height adjustment and stable support. The support plate 31 contacts the ground or support surface, providing the bottom foundation support for the entire structure. When it is necessary to adjust the height of the reinforcement seat 21 to adapt to the terrain or pipeline installation requirements, the knob 36 at the end of the bidirectional threaded screw 35 is rotated. Since the bidirectional threaded screw 35 is installed between the two fixed plates 34, and the two movable seats 32 are respectively engaged with the two reverse threads of the bidirectional threaded screw 35, under the limiting action of the guide rod 37, the movable seats 32 will move closer or further away along the guide rod 37. The movement of the movable seats 32 drives the flip support rod 33 hinged to it to flip. When the movable seats 32 move closer, the included angle of the flip support rod 33 decreases, lifting the reinforcement seat 21; when the movable seats 32 move further away, the included angle of the flip support rod 33 increases, and the reinforcement seat 21 descends. Through this adjustment, the connecting flange 11 is ensured to be in a horizontal or suitable position, further enhancing the stability and environmental adaptability of the entire reinforcement structure, so that the pipeline connection can remain stable and reliable under the action of external forces such as water flow impact.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
