Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a water supply and drainage pipeline connection mechanism. Background Technology

[0002] Water supply and drainage pipeline engineering is an important component of the water supply and drainage system, playing a key role in the entire system. It includes the pipeline system itself and various structures on the pipeline system, such as pumping stations, water storage tanks, pipe bridges, gate wells, sewage inspection wells, and rainwater inlets. Among them, the tee pipe plays a key role in the connection of water supply and drainage pipelines, which can realize the flexible turning and distribution of fluids in the pipeline, ensuring the smooth operation and efficient management of the water supply and drainage system.

[0003] However, in existing tee pipes, water often carries impurities. When water falls vertically from the top of the tee pipe and enters its interior, the water velocity increases dramatically due to gravity. This high-speed water flow carrying impurities will eventually violently impact the bottom of the tee pipe, causing continuous wear and reducing its service life. Furthermore, the impact on the bottom of the tee pipe will cause vibrations, which will propagate along the pipe structure to both sides. Over time, the connection between the tee pipe and adjacent pipes may gradually become damaged due to stress concentration, thereby reducing the strength and stability of the entire pipe connection mechanism and affecting its normal use, resulting in poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the tee pipe is used in the pipeline connection mechanism, its service life and connection strength are easily reduced due to the impact of water flow carrying impurities, thus affecting the normal use of the entire pipeline connection mechanism. Therefore, a water supply and drainage pipeline connection mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water supply and drainage pipe connection mechanism includes a spherical elbow and a support base. A second inlet pipe is installed at the top of the spherical elbow, and corrugated pipes are installed on both sides of the elbow. A first outlet pipe is installed at the outward-facing end of each corrugated pipe. The mechanism also includes:

[0007] A fluid buffer mechanism is provided on the second inlet pipe and the two first outlet pipes to reduce the impact force of the water flow entering the spherical elbow.

[0008] A flow guiding and buffering mechanism includes a rotating assembly, multiple first fan blades and multiple second fan blades. The multiple first fan blades and multiple second fan blades are all mounted on the rotating assembly. The first fan blades and the second fan blades are rotatably connected to the inner walls of two first water outlet pipes through the rotating assembly.

[0009] Preferably, the fluid buffer mechanism includes a diffuser and two converging tubes. The diffuser is installed at the top of the second inlet pipe, and a first inlet pipe is installed at the top of the diffuser. The two converging tubes are respectively installed at the outward ends of the two first outlet pipes. A second outlet pipe is installed at the outward end of the converging tube. The opening at the top of the diffuser is smaller than the opening at its bottom, and the opening at the end of the converging tube facing the first outlet pipe is larger than the opening at the end facing the second outlet pipe.

[0010] Preferably, a first rubber pad and two second rubber pads are fixedly installed on the top of the support base. The first rubber pad is located between the two second rubber pads, and the top of the first rubber pad is fixedly connected to the bottom of the spherical elbow. The top of the second rubber pad is fixedly connected to the corresponding first water outlet pipe, tapering pipe and second water outlet pipe.

[0011] Preferably, the first fan blade is located directly below the second water inlet pipe, and multiple second fan blades are evenly distributed on both sides of the first fan blade. Both the first and second fan blades are arranged in a curved structure, with the degree of curvature of the first fan blade being greater than that of the second fan blade, and the area of ​​the first fan blade being greater than that of the second fan blade.

[0012] Preferably, the first fan blade is provided with a plurality of through holes 1, and the second fan blade is provided with a plurality of through holes 2. The distribution density of the plurality of through holes 2 is greater than the distribution density of the plurality of through holes 1, and the diameter of the through holes 1 is greater than the diameter of the through holes 2.

[0013] Preferably, the rotating assembly includes two rotating rings, which are rotatably connected to the inner walls of two first water outlet pipes respectively. Multiple connecting rods are installed on the inner sidewalls of the rotating rings. Both rotating rings are fixedly connected to a transmission rod through their connecting rods. Multiple first fan blades and multiple second fan blades are evenly installed on the outer wall of the transmission rod.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. This utility model, through the cooperation of a spherical elbow, a corrugated pipe, a second inlet pipe, a first outlet pipe, a fluid buffer mechanism, and a flow guiding buffer mechanism, can not only effectively reduce the impact force of fluid on the spherical elbow and the second outlet pipe, as well as the erosion of the spherical elbow by impurities, by utilizing the characteristics of the expanding and contracting pipes and the shape of the spherical elbow itself, but also further reduce the impact force of fluid by utilizing the setting of the first and second fan blades, and make the distribution of impurities in the water flow and the water flow velocity more uniform. This ensures the service life of the entire pipeline connection mechanism, while also effectively improving the stability and durability of the entire pipeline system, thereby ensuring the normal use of the entire pipeline connection mechanism.

[0016] 2. By combining the second water inlet pipe and the fluid buffer mechanism, this utility model can effectively reduce the risk of pipe blockage caused by the accumulation of impurities in the water flow by utilizing the second water inlet pipe with a larger diameter, thereby ensuring the normal delivery of water flow and the normal use of the entire pipe connection mechanism.

[0017] 3. By incorporating the first and second rubber pads, this invention effectively reduces vibrations in the spherical elbow and its adjacent pipe structures when they vibrate due to water flow impact. This effectively prevents stress concentration damage at the connection points between the pipe structures on both sides of the spherical elbow and the external water pipe, thus ensuring the stability of the connection between the pipe structures on both sides and the water pipe. Furthermore, the corrugated pipe not only utilizes its elastic deformation characteristics to effectively reduce the impact force of the fluid directly acting on the first outlet pipe, but also uses its flexible structure to isolate the vibration of the spherical elbow caused by water flow impact to a certain extent, further ensuring the stability of the connection between the pipe structures on both sides and the water pipe, thereby further ensuring the normal use of the entire pipe connection mechanism.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 4 A water supply and drainage pipe connection mechanism includes a spherical elbow 8 and a support base 9. A second inlet pipe 3 is installed at the top of the spherical elbow 8, and corrugated pipes 4 are installed on both sides of it. A first outlet pipe 5 is installed at the outward end of the corrugated pipe 4. A fluid buffer mechanism is provided on the second inlet pipe 3 and the two first outlet pipes 5 to reduce the impact force of water flow entering the spherical elbow 8. The fluid buffer mechanism includes a diffuser 2 and two converging pipes 6. The diffuser 2 is installed at the top of the second inlet pipe 3, and a first inlet pipe 1 is installed at the top of the diffuser 2. The two converging pipes 6 are respectively installed on the two first outlet pipes 3. The outlet pipe 5 has an outward-facing end, and the converging pipe 6 has an outward-facing end with a second outlet pipe 7 installed on it. The opening at the top of the expanding pipe 2 is smaller than the opening at its bottom. The opening at the end of the converging pipe 6 facing the first outlet pipe 5 is larger than the opening at the end facing the second outlet pipe 7. The top of the support base 9 is fixedly installed with a first rubber pad 10 and two second rubber pads 11. The first rubber pad 10 is located between the two second rubber pads 11, and the top of the first rubber pad 10 is fixedly connected to the bottom of the spherical elbow 8. The top of the second rubber pad 11 is fixedly connected to the corresponding first outlet pipe 5, converging pipe 6, and second outlet pipe 7.

[0025] Two first outlet pipes 5 are equipped with flow guiding and buffering mechanisms to guide and buffer the water flow entering the spherical elbow 8. The flow guiding and buffering mechanisms include a rotating assembly, multiple first fan blades 14, and multiple second fan blades 15. The multiple first fan blades 14 and multiple second fan blades 15 are all mounted on the rotating assembly. The first fan blades 14 and second fan blades 15 are rotatably connected to the inner walls of the two first outlet pipes 5 via the rotating assembly. The rotating assembly enables the first fan blades 14 and second fan blades 15 to rotate. The first fan blade 14 is located directly below the second inlet pipe 3, and the multiple second fan blades 15 are evenly distributed on both sides of the first fan blade 14. Both the first fan blades 14 and second fan blades 15 are arranged in a curved structure. The first fan blade 14... The degree of curvature is greater than that of the second blade 15, and the area of ​​the first blade 14 is greater than that of the second blade 15. Multiple through holes 1 are provided through the first blade 14, and multiple through holes 2 are provided through the second blade 15. The distribution density of the multiple through holes 2 is greater than that of the multiple through holes 1. The diameter of the through holes 1 is greater than that of the through holes 2. The rotating assembly includes two rotating rings 12, which are rotatably connected to the inner walls of the two first water outlet pipes 5 respectively. Multiple connecting rods 16 are installed on the inner side wall of the rotating rings 12. Both rotating rings 12 are fixedly connected to the transmission rod 13 through the connecting rods 16. Multiple first blades 14 and multiple second blades 15 are evenly installed on the outer wall of the transmission rod 13.

[0026] In use, this invention first connects the first inlet pipe 1 at the top of the spherical elbow 8 to the water pipe at the inlet, and connects the second outlet pipes 7 on both sides of the spherical elbow 8 to the water pipe at the outlet. In a conventional tee pipe, when water flows vertically down from the top of the tee pipe, the water velocity increases rapidly due to gravity, and the water also carries impurities. This causes the water entering the tee pipe to impact the bottom of the tee pipe vertically with these impurities, resulting in wear on the bottom material. Furthermore, the vibration generated by the impact is transmitted through the pipe structure to both sides of the tee pipe. Over time, the connection between the tee pipe and adjacent pipes may gradually become damaged due to stress concentration, thus reducing the strength and stability of the entire pipe connection mechanism. Therefore, in this invention… In this new design, the first inlet pipe 1 and the second inlet pipe 3 are directly equipped with diffuser pipes 2. Under the action of the diffuser pipes 2, the diameter of the pipe through which the water flows gradually increases, thereby gradually reducing the water flow velocity. This design can effectively reduce the impact force of the water flow entering the spherical elbow 8 on its bottom, thereby enhancing the strength and stability of the entire pipe connection mechanism. At the same time, compared with the first inlet pipe 1, the second inlet pipe 3 with a larger diameter can accommodate more instantaneous flow (because the opening at the top of the diffuser pipe 2 is smaller than the opening at its bottom, the diameter of the second inlet pipe 3 is larger than that of the first inlet pipe 1), reducing the risk of pipe blockage caused by the accumulation of impurities in the water flow, thereby ensuring the normal delivery of water flow and the normal use of the entire pipe connection mechanism.

[0027] When water flows into the spherical elbow 8, its shape allows for smoother flow as the fluid turns and enters the first outlet pipe 5, reducing the impact force caused by the turn, i.e., reducing the impact force on the inner bottom wall of the spherical elbow 8, effectively ensuring its service life. Simultaneously, the shape of the spherical elbow 8 causes the water flowing inside to swirl, causing impurities within the water to swirl as well, further reducing erosion of the spherical elbow 8 by impurities and ensuring its service life. When the water flows out through the first outlet pipe 5, the flow velocity of the water in the first outlet pipe 5 is relatively low compared to that in the second outlet pipe 7 because the diameter of the first outlet pipe 5 is larger than that of the second outlet pipe 7. Therefore, when the water flows through the converging pipe 6 into the smaller diameter second outlet pipe 7, the increase in its flow velocity will be relatively gradual. Specifically, compared to the fluid directly impacting the second outlet pipe 7 from the spherical elbow 8, the impact force of the fluid on the second outlet pipe 7 will be significantly reduced through the buffering effect of the first outlet pipe 5 and the converging pipe 6, thereby reducing the risk of damage to the second outlet pipe 7 due to water flow impact.

[0028] Furthermore, the first blade 14 and the second blade 15 in the spherical elbow 8 can change the direction of the fluid, reducing the direct impact of the high-speed fluid on the spherical elbow 8 and the pipe structures on both sides (i.e., the bellows 4, the first outlet pipe 5, the tapered pipe 6, and the second outlet pipe 7). This helps to reduce the vibration and wear of the pipe structure caused by the fluid impact. At the same time, as the water flow impacts the first blade 14 and the second blade 15, they will rotate, which can effectively enhance the swirling motion of the water flow in the spherical elbow 8 and allow impurities to enter the side pipe structure more evenly with the water flow. This avoids the problem of excessive wear on the pipe wall caused by excessive accumulation of impurities in a certain place, thus effectively ensuring the service life of the entire pipe connection mechanism.

[0029] Since the flow velocity is usually highest in the central area of ​​the spherical elbow 8, the first blade 14 with a larger curvature (i.e., the first blade 14 with a larger curvature) located directly below the second inlet pipe 3 can force the high-speed fluid to diffuse outward, reducing the peak flow velocity in the core area. At the same time, when the fluid passes through the first blade 14, it will generate friction with its surface, thereby dissipating some energy. This helps to reduce the direct impact of the fluid on the pipe wall. The second blade 15 with a smaller curvature (i.e., the second blade 15 with a smaller curvature) guides the fluid to smoothly enter the pipe structure on both sides of the spherical elbow 8 with its relatively gentle curvature. This makes the flow velocity of the fluid entering the side pipe structure more uniform, reducing the additional stress on the side pipe structure caused by uneven flow velocity, thereby improving the stability and durability of the entire pipeline system.

[0030] Because the first blade 14, located directly below the second inlet pipe 3, has a large area and curvature, and the fluid velocity is high and easily forms concentrated impacts at this location, opening multiple large-diameter through holes on the first blade 14 can effectively divert the high-speed fluid and reduce the local flow velocity, thereby further reducing the direct impact of the fluid on the pipe wall. On the other hand, because the second blade 15 has a small area and curvature, and the impact of the fluid on it is relatively dispersed, opening multiple small-diameter and densely distributed through holes on the second blade 15 can reduce the frontal impact of the fluid on the second blade 15, thereby effectively ensuring the service life of the second blade 15.

[0031] Because a first rubber pad 10 is provided between the spherical elbow 8 and the support base 9, and a second rubber pad 11 is provided between the pipe structures on both sides of the spherical elbow 8 and the support base 9, when the spherical elbow 8 and the pipe structures on both sides vibrate due to water flow impact, the first rubber pad 10 and the second rubber pad 11 can be used to absorb the vibration energy, thereby achieving effective vibration reduction of the spherical elbow 8 and the pipe structures on both sides. This effectively prevents the pipe structures on both sides of the spherical elbow 8 from being damaged at the connection with the external water pipe due to stress concentration, thus effectively ensuring the connection stability of the pipe structures on both sides and the water pipe connection, and effectively ensuring the normal use of the entire pipe connection mechanism.

[0032] Furthermore, when fluid flows from the spherical elbow 8 into the pipe structures on both sides, the elastic deformation characteristics of the corrugated pipe 4 can effectively absorb and disperse some of the fluid impact energy, thereby effectively reducing the impact force directly acting on the first outlet pipe 5. Since the spherical elbow 8 is prone to vibration or slight displacement under fluid impact, the corrugated pipe 4 can use its flexible structure to isolate the vibration caused by the impact to a certain extent, thereby further ensuring the connection stability of the pipe structures on both sides and the water pipe connection.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
