Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering, and more specifically, to an anti-silting type sewage pipe for municipal engineering. Background Art

[0002] Sewage pipe refers to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants.

[0003] The sewage pipe network is composed of pipes and their ancillary structures for collecting and transporting urban sewage. The sewage flows from the branch pipes into the trunk pipes, then into the main pipes, and finally into the sewage treatment plant. The pipes are distributed from small to large, similar to rivers, in a tree-like shape, which is completely different from the circulation and penetration of the water supply network. Sewage generally flows from high to low in the pipes by relying on the water level difference at both ends of the pipes. The inside of the pipes is not under pressure, that is, it flows by gravity. The height difference of the sewage pipes in some sewage pipe networks that decreases with the flow direction is small, which makes it easy for solid impurities to accumulate at the bottom of the sewage pipes when they are in use. In order to ensure the normal discharge function of the sewage pipes, it is necessary to regularly desilt the sewage pipes that are prone to siltation. Therefore, a structure is set to solve the problem that some sewage pipes are prone to siltation when in use, affecting the sewage performance of the sewage pipes.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide an anti-siltation type sewage pipe for municipal engineering.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: the anti-siltation type sewage pipe for municipal engineering includes a plurality of auxiliary connecting pipes arranged in sequence along the water flow direction, and a main sewage pipe for connecting them is provided between two adjacent auxiliary connecting pipes, and the auxiliary connecting pipes and the main sewage pipe are provided with auxiliary dredging parts which are against their bottom walls and swing with changes in their internal flow rates.

[0007] The present invention is further configured such that: the swaying frequency of the dredging part is consistent with the flow rate change frequency in the auxiliary connecting pipe and the main sewage pipe, and the swaying amplitude of the auxiliary dredging part is proportional to the flow rate in the auxiliary connecting pipe and the main sewage pipe.

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The anti-siltation municipal engineering sewage pipe, such as Figure 1 As shown, it includes a plurality of auxiliary connecting pipes 1 arranged in sequence along the water flow direction, a main sewage pipe 2 for connecting the two adjacent auxiliary connecting pipes 1 is provided between them, and a structure for discharging sewage is formed by the joint action of the auxiliary connecting pipes 1 and the main sewage pipe 2, so that the structure as a whole can achieve stable drainage of sewage, and auxiliary dredging parts are provided in the auxiliary connecting pipes 1 and the main sewage pipe 2, which are against their bottom walls and swing with the change of internal flow, and the auxiliary dredging parts are set to swing when the sewage flows through the auxiliary connecting pipes 1 and the main sewage pipe 2, and the auxiliary dredging parts are connected with the auxiliary connecting pipes 1 and the main sewage pipe 2 is against the bottom wall, so that the auxiliary dredging part will exert a force on the solid deposited at the bottom of the auxiliary connecting pipe 1 and the main sewage pipe 2 when swinging, so as to stir the deposited solid impurities, so that the water flow flowing through the auxiliary connecting pipe 1 and the main sewage pipe 2 can drive the stirred solid impurities to flow together with the water flow, so as to achieve stable cleaning of the impurities deposited inside the auxiliary connecting pipe 1 and the main sewage pipe 2, and achieve stable dredging inside the auxiliary connecting pipe 1 and the main sewage pipe 2, thereby reducing the amount of impurities deposited inside the auxiliary connecting pipe 1 and the main sewage pipe 2 and the influence of the deposited impurities on the overall drainage performance of the structure.

[0025] like Figure 1As shown, the swaying frequency of the dredging part is consistent with the flow change frequency in the auxiliary connecting pipe 1 and the main sewage pipe 2. When the water flow and flow velocity in the auxiliary connecting pipe 1 and the main sewage pipe 2 are changed, the impact force and impact effect of the water flow on the dredging part will change, and the force and effect of the water flow on the dredging part will change, so that the auxiliary dredging part can realize different swaying and cleaning processes inside the auxiliary connecting pipe 1 and the main sewage pipe 2, so that the solid impurities accumulated in the auxiliary connecting pipe 1 and the main sewage pipe 2 are stirred up, and then the flowing water can realize the impurities accumulated in the auxiliary connecting pipe 1 and the main sewage pipe 2. Stable cleaning, the swing amplitude of the auxiliary dredging part is proportional to the flow rate in the auxiliary connecting pipe 1 and the main sewage pipe 2, and the auxiliary dredging part includes a first flexible part 3 with a length consistent with the sum of the lengths of several auxiliary connecting pipes 1 and several main sewage pipes 2. The first flexible part 3 is set to be a rope made of nylon material. The good weather resistance and high strength of the nylon material are used to ensure that the first flexible part 3 has good and stable structural strength and weather resistance, and ensure that the first flexible part 3 has better stability and service life, thereby ensuring better service life and stability of the auxiliary dredging part as a whole, and ensuring that the overall dredging function of the auxiliary dredging part is more stable.

[0026] like Figure 1-Figure 3 As shown, a swing rod 4 is hinged in the auxiliary connecting tube 1 and fixedly connected to the first flexible member 3 by means of adhesive. The swing rod 4 is made of aluminum alloy. The high structural strength, corrosion resistance and light weight of this type of material are utilized to ensure that the swing rod 4 has better strength and is lighter. A plug-in tube 5 with openings opposite and symmetrically arranged is fixedly connected to the auxiliary connecting tube 1 by means of adhesive. The plug-in tube 5 is made of aluminum alloy to ensure that the plug-in tube 5 is lighter and has better strength. A connecting rod 6 rotatably connected to the swing rod 4 is inserted between the two plug-in tubes 5. The connecting rod 6 is rotatably connected to the swing rod 4 and is inserted on the plug-in tube 5. This arrangement enables the swing rod 4 to swing better when subjected to external force, thereby ensuring that the driving function of the swing rod 4 can be stably realized.

[0027] like Figure 2-Figure 6The auxiliary connecting pipe 1 located at the bottom side is fixedly connected with a clearance groove 7 with a top opening and for the bottom of the swing rod 4 to penetrate. The set clearance groove 7 is used to provide a clearance effect during the swinging process of the swing lever, ensuring that the swing rod 4 can swing stably and drive the first flexible member 3 to move. The inner bottom surface of the clearance groove 7 is lower than the inner bottom surface of the auxiliary connecting pipe 1. The auxiliary connecting pipe 1 located at the top side is fixedly connected with a clearance pipe 8. The swing rod 4 is fixedly connected with a spring 9 symmetrically arranged and fixedly connected to the clearance pipe 8. The length direction of the spring 9 is consistent with the direction of the water flow. The top of the tube 8 is covered with a top cover 10, and the top cover 10 is used to achieve stable covering of the give way tube 8, thereby achieving stable shielding and protection of the spring 9, ensuring that the state of the spring 9 and the functions it can produce are more stable. The swing rod 4 will stretch the spring 9 for elastic deformation during the swinging process, and the spring 9 will generate elastic force during the elastic deformation. After the force exerted by the water flow on the swing rod 4 disappears, the swing rod 4 will be reset under the action of the elastic force generated by the elastically deformed spring 9, thereby driving the first flexible member 3 to be stably reset.

[0028] like Figure 4-Figure 6 As shown, a symmetrically arranged limit plate 11 is fixedly connected to the swing rod 4 near the bottom side by welding. The limit plate 11 is set to an aluminum alloy material. A first baffle block 12 is provided between the two limit plates 11 and is sleeved on the swing rod 4. The first baffle block 12 is set to a PE material. The set limit plate 11 is used to achieve stable limiting of the first baffle block 12, ensuring that the first baffle block 12 can be in a relatively stable position, so that the water flow can better exert an impact force on the first guide block, and then better exert an impact force on the swing rod 4, and then better drive the first flexible member 3 to desilt.

[0029] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the first flexible member 3 is provided with a plurality of knots 13 distributed in an array, the knots 13 are formed by knotting, and the first flexible member 3 located at the knots 13 is fixedly connected with a second flexible member 14 by bonding with an adhesive, and the second flexible member 14 is set to be a nylon rope material, and the high structural strength and good weather resistance of the nylon material are used to ensure that the second flexible member 14 has good and stable structural strength and weather resistance, and ensure that the second flexible member 14 has good and stable structural strength and service life, and the first flexible member 3 will drive the knots 13 to move during the movement, and the knots 13 will also drive the second flexible member 14 to move during the movement, and the amount of solid impurities deposited by the first flexible member 3 as a whole during the movement is increased by the provision of the knots 13 and the second flexible member 14, so as to enhance the overall dredging performance of the auxiliary dredging part, so that the dredging effect of the overall structure is better and more stable, and the inner bottom surface of the main sewage pipe 2 is fixedly connected with a plurality of limiters distributed in an array and used to limit the position of the knots 13. The U-shaped member 15 is provided with a limit U-shaped member 15, so that the knot 13 between the two limit U-shaped members 15 can be stably located between the two limit U-shaped members 15, so that the knot 13 can stably slide back and forth between the two limit U-shaped members 15, thereby realizing stable stirring of the sludge in the area between the two limit U-shaped members 15, and reducing the situation where the knot 13 fails to stir the corresponding rest due to the disorderly movement of the knot 13, so that the water flowing through can better carry away the deposited impurities, and reduce the siltation inside the structure. A second baffle block 16 is fixedly connected to the first flexible member 3 near the water outlet, and the second guide block is set to PE material. With the help of the second baffle block 16, the water flowing through can apply a flushing force to the first flexible member 3 with the help of the second baffle block 16, thereby driving the first flexible member 3 to move and realize stable stirring of the deposited impurities, so that the deposited impurities can be better washed away by the flowing water after being stirred, and the solid impurities deposited inside the structure are reduced.
