Description
Technical Field
[0001] This invention relates to the field of stormwater and sewage diversion technology, and in particular to a temporary diversion device for stormwater and sewage pipe networks in municipal engineering. Background Technology
[0002] In the construction and maintenance of municipal engineering projects and pipeline networks, temporary diversion of stormwater and sewage pipe networks is a crucial step in ensuring smooth construction and preventing sewage overflow and environmental pollution. Currently, most existing temporary diversion devices for stormwater and sewage pipe networks in municipal engineering projects use fixed-connection diversion pipes to divert upstream sewage to downstream pipe networks or temporary discharge points.
[0003] After each diversion, the water level of the upstream sewage remains at the lower end of the fixed-connection diversion pipe. As sewage continuously enters from the upstream, the diversion pipe needs to remain operational. During continuous diversion, energy is constantly consumed, resulting in high energy consumption. Furthermore, impurities may enter the diversion pipe during the upstream sewage diversion process. If not cleaned in time, these impurities will cause blockages, affecting the continuous diversion effect. Therefore, a temporary diversion device for municipal engineering stormwater and sewage pipe networks needs to be designed. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a temporary drainage device for municipal engineering stormwater and sewage pipe networks that can ensure continuous drainage without consuming a lot of energy.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a temporary diversion device for municipal engineering stormwater and sewage pipe networks, comprising a diversion box, wherein the diversion box is provided with a water storage cavity with a sealing cover plate on the top, and a diversion pipe is provided on the sealing cover plate, and further comprising: The drainage seat is connected to the drainage pipe, and has an internal cavity and a corrugated pipe at the bottom for connecting with the upstream of the rainwater and sewage pipe network. A siphon assembly is disposed within the drainage seat and is used to open or close the connection between the drainage tube and the corrugated tube. A discharge pipe, connected to the water storage chamber, is installed on the side wall of the water storage chamber.
[0006] Furthermore, the siphon assembly includes a sealing plate that is slidably disposed within the drainage seat, a float ball disposed at the bottom of the sealing plate, a fixing rod disposed at the top of the sealing plate and passing through the upper end of the drainage seat, and a fixing plate disposed at the top of the fixing rod, wherein a tension spring is disposed between the fixing plate and the drainage seat.
[0007] Furthermore, it also includes a telescopic assembly for extending the bellows. The telescopic assembly includes a rotating seat fixed to the side wall of the drainage seat, a lead screw rotatably mounted on the rotating seat, a side rod disposed at the bottom of the rotating seat and sleeved on the lead screw, a fixing ring sleeved on the bellows, and a driving member disposed on the fixing plate for driving the lead screw to rotate. The bottom end of the side rod is fixedly connected to the fixing ring.
[0008] Furthermore, the driving component includes a fixed rack fixed to the side wall of the fixed plate, a rotating rod rotatably mounted on the side wall of the drainage seat, and a fixed gear disposed on the rotating rod and meshing with the fixed rack. A driving bevel gear is disposed on the rotating rod, and a driven bevel gear meshing with the driving bevel gear is disposed at the top end of the lead screw.
[0009] Furthermore, the lower end face of the corrugated pipe after elongation is located above the lower end face of the drainage pipe, and the length of the side rod is greater than the height difference between the drainage seat and the sealing plate.
[0010] Furthermore, the guide box is also provided with a sludge chamber with a sealing cover plate on the top. A drain pipe communicating with the corrugated pipe is provided on one side of the sludge chamber. A filter screen is provided inside the corrugated pipe above the drain pipe. A pressure box for providing negative pressure to the drain pipe is provided on the other side of the sludge chamber.
[0011] Furthermore, the bottom of the discharge pipe is provided with a pressure regulating component for adjusting the pressure inside the pressure box. The pressure regulating component includes a piston plate that is sealed and slidably disposed in the pressure box, a connecting post disposed at one end of the piston plate, a reciprocating screw threadedly connected in the connecting post, and a drive component for driving the reciprocating screw to rotate.
[0012] Furthermore, the drive assembly includes a round rod fixedly connected to the reciprocating screw and a discharge seat disposed at the bottom end of the discharge pipe. The discharge seat has a cavity for receiving water discharged from the discharge pipe. The round rod passes through the discharge seat and is provided with multiple impellers. The impellers are used to drive the round rod to rotate under the drive of the water discharged from the discharge pipe.
[0013] Furthermore, the bottom of the discharge pipe is configured as a funnel shape, and the connection position between the bottom of the discharge pipe and the discharge seat is radially staggered with the round rod.
[0014] Furthermore, a one-way exhaust port is provided at the end of the pressure box away from the discharge seat.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a diversion pipe on the diversion box, which is connected to a corrugated pipe for insertion into the upstream of the stormwater and sewage pipe network. A siphon assembly is provided on the diversion seat to open or close the connection between the corrugated pipe and the diversion pipe.

No additional energy consumption is required, and the energy consumption can be greatly reduced through the siphon assembly. 2. This invention features a drain pipe for extracting impurities trapped by the filter screen inside the corrugated pipe, and a pressure box to provide negative pressure to the drain pipe. This allows the impurities on the filter screen to be cleaned through the drain pipe during the drainage process, preventing blockage and ensuring the normal operation of the drainage process. In addition, the pressure box is powered by the sewage upstream of the rainwater and sewage pipe network extracted by the siphon assembly, eliminating the need for an additional power source, effectively reducing energy consumption, and ensuring the drainage effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1-12 The present invention relates to a temporary diversion device for municipal engineering stormwater and sewage pipe networks, comprising a diversion box 1, wherein the diversion box 1 is provided with a water storage chamber 11 having a sealing cover plate 12 on its top, and a diversion pipe 13 is provided on the sealing cover plate 12, and further comprising: The drainage seat 2 is connected to the drainage pipe 13, and has an internal cavity 21 and a corrugated pipe 22 for connecting to the upstream of the rainwater and sewage pipe network at the bottom. The siphon assembly 3 is disposed in the drainage seat 2 and is used to open or close the connection between the drainage tube 13 and the corrugated tube 22. The discharge pipe 14 is connected to the water storage chamber 11 and is disposed on the side wall of the water storage chamber 11.
[0020] By inserting a corrugated pipe 22 into the upstream of the stormwater and sewage pipe network, when the sewage volume in the upstream stormwater and sewage pipe network increases, the siphon component 3 inside the diversion seat 2 will open under the action of sewage, sending sewage from the corrugated pipe 22 through the diversion seat 2 and the diversion pipe 13 into the water storage chamber 11. Under the action of the siphon component 3, the water flow in the corrugated pipe 22, the diversion seat 2 and the diversion pipe 13 will form a siphon phenomenon, thereby automatically completing the diversion action without additional energy consumption, which greatly reduces the energy consumption of diversion treatment.
[0021] In one embodiment, the siphon assembly 3 includes a sealing plate 31 that is slidably disposed within the drainage seat 2, a float 32 disposed at the bottom of the sealing plate 31 via a connecting rod 36, a fixing rod 33 disposed at the top of the sealing plate 31 and passing through the upper end of the drainage seat 2, and a fixing plate 34 disposed at the top of the fixing rod 33. A tension spring 35 is disposed between the fixing plate 34 and the drainage seat 2. This design allows the float 32 to rise with the water level in the upstream of the stormwater and sewage pipe network. As the float 32 rises, it drives the fixing rod 33 and the fixing plate 34 upwards, thereby connecting the corrugated pipe 22, the drainage seat 2, and the drainage pipe 13, causing the water within them to flow and forming a siphon effect. This automatically completes the drainage action without requiring additional energy, significantly reducing the energy consumption of the drainage process.
[0022] In one embodiment, a telescopic assembly 4 for extending the corrugated pipe 22 is also included. The telescopic assembly 4 includes a rotating seat 41 fixed to the side wall of the drainage seat 2, a lead screw 42 rotatably mounted on the rotating seat 41, a side rod 43 disposed at the bottom of the rotating seat 41 and threaded onto the lead screw 42, a fixing ring 44 sleeved on the corrugated pipe 22, and a driving member 45 disposed on the fixing plate 34 for driving the lead screw 42 to rotate. The bottom end of the side rod 43 is fixedly connected to the fixing ring 44. With this design, by setting the driving member 45, the corrugated pipe 22 can be driven to extend and retract. Thus, during the siphoning process, the bottom of the corrugated pipe 22 can be moved downward by the driving member 45, allowing the corrugated pipe 22 to be inserted deeper into the upstream sewage during the drainage process, and increasing the space inside the corrugated pipe 22, enabling a larger capacity drainage treatment.
[0023] In one embodiment, the driving component 45 includes a fixed rack 451 fixed to the side wall of the fixed plate 34, a rotating rod 452 rotatably mounted on the side wall of the diversion seat 2, and a fixed gear 453 disposed on the rotating rod 452 and meshing with the fixed rack 451. A driving bevel gear 454 is disposed on the rotating rod 452, and a driven bevel gear 455 meshing with the driving bevel gear 454 is disposed at the top of the lead screw 42. With this design, by setting the fixed rack 451 on the side wall of the fixed plate 34, when the upstream sewage level rises, the siphon assembly 3 moves upward, driving the fixed rack 451 to move upward. Through the meshing of the fixed gear 453 with the fixed rack 451, the rotating rod 452 rotates. With the cooperation of the driving bevel gear 454 and the driven bevel gear 455, the lead screw 42 rotates, thereby driving the side rod 43 downward, achieving the extension of the bellows 22.
[0024] In one embodiment, the lower end face of the extended corrugated tube 22 is located above the lower end face of the drainage tube 13, and the length of the side rod 43 is greater than the height difference between the drainage seat 2 and the sealing plate 31. This design, by positioning the lower end face of the extended corrugated tube 22 above the lower end face of the drainage tube 13, ensures the normal operation of the siphon process. Furthermore, the greater length of the side rod 43 than the height difference between the drainage seat 2 and the sealing plate 31 ensures an effective connection between the side rod 43 and the lead screw 42, preventing separation.
[0025] In one embodiment, the guide box 1 is further provided with a sludge chamber 16 with a sealing cover plate 17 on the top. A drain pipe 18 communicating with the corrugated pipe 22 is provided on one side of the sludge chamber 16. A filter screen 23 is provided inside the corrugated pipe 22 above the drain pipe 18. The other side of the sludge chamber 16 is connected to a pressure box 5 for providing negative pressure to the drain pipe 18 through a one-way air outlet pipe 52. With this design, by setting up the sludge chamber 16, impurities inside the corrugated pipe 22 extracted by the drain pipe 18 can be stored. By setting up the pressure box 5, negative pressure can be provided to the drain pipe 18, thereby facilitating the extraction of impurities inside the corrugated pipe 22 by the drain pipe 18. The sludge chamber 16 is connected to the pressure box 5 through the one-way air outlet pipe 52, so that the pressure box 5 can only extract air from the sludge chamber 16 and will not send air into the sludge chamber 16.
[0026] In one embodiment, the bottom of the discharge pipe 14 is provided with a pressure regulating component 6 for adjusting the pressure inside the pressure box 5. The pressure regulating component 6 includes a piston plate 61 that is slidably disposed in the pressure box 5, a connecting post 62 disposed at one end of the piston plate 61, a reciprocating screw 63 threadedly connected in the connecting post 62, and a drive component 64 for driving the reciprocating screw 63 to rotate. With this design, by providing the drive component 64, the reciprocating screw 63 can be driven to move back and forth, thereby driving the connecting post 62 and the piston plate 61 to move back and forth. During the outward movement of the piston plate 61, the pressure inside the pressure box 5 decreases, thereby providing negative pressure to the drain pipe 18, realizing the extraction of impurities accumulated inside the bellows 22 and drawing them into the sludge chamber 16.
[0027] In one embodiment, the drive assembly 64 includes a round rod 641 fixedly connected to the reciprocating screw 63 and a discharge seat 642 disposed at the bottom end of the discharge pipe 14. The discharge seat 642 has a cavity 643 for receiving water discharged from the discharge pipe 14. The round rod 641 passes through the discharge seat 642 and is provided with a plurality of impellers 644. The impellers 644 are used to drive the round rod 641 to rotate under the drive of the water discharged from the discharge pipe 14. With this design, by setting the impellers 644, they can rotate under the impact of water when water is discharged into the discharge pipe 14, thereby driving the round rod 641 to rotate. The round rod 641 is fixedly connected to the reciprocating screw 63, thus driving the reciprocating screw 63 to rotate, realizing the reciprocating movement of the piston plate 61 in the pressure box 5.
[0028] In one embodiment, the bottom of the discharge pipe 14 is configured as a funnel shape, and the connection position between the bottom of the discharge pipe 14 and the discharge seat 642 is radially staggered with that of the round rod 641. This design, by setting the bottom of the discharge pipe 14 to a funnel shape, can utilize the potential energy of the falling water to impact the impeller 644 with a greater force, facilitating the rotation of the impeller.
[0029] In one embodiment, a one-way vent 51 is provided at the end of the pressure box 5 away from the discharge seat 642. With this design, when the piston plate 61 moves inward in the pressure box 5, excess gas can be discharged to the outside of the pressure box 5 through the one-way vent 51, thereby preventing impurities extracted from the drain pipe 18 from being sent back into the bellows 22.
[0030] Preferably, multiple filter frames 15 are fixedly installed at the bottom of the sealing cover plate 12. This design enables multiple filtration of the water discharged through the discharge pipe 14, ensuring the cleanliness of the water discharged from the discharge pipe 14 and thus preventing impurities in the water discharged from the discharge pipe 14 from affecting the rotation of the impeller 644.
[0031] Preferably, the middle portion of both the drainage pipe 13 and the sewage pipe 18 is made of flexible tubing. This design allows for adjustment of the drainage pipe 13 and the sewage pipe 18 without interfering with the extension and retraction of the corrugated pipe 22.
[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
