Description

Technical Field

[0001] This application relates to the field of pipeline dredging technology, and in particular to an inverted siphon type urban sewage pipeline system. Background Technology

[0002] When a channel is at a similar elevation to a road or ditch and they intersect at the same level, a structure is needed to allow water to pass under the road or ditch. This structure is usually called an inverted siphon pipe.

[0003] Inverted siphon pipes are high at both ends and low in the middle. When the water flow velocity in the inverted siphon pipe is low, solid impurities such as mud and sand in the water flow are prone to accumulate in the inverted siphon pipe, causing blockage.

[0004] In existing technologies, to reduce sediment buildup in inverted siphon pipes, devices for sediment collection or filtration are typically installed at the inlet of the pipe. These devices filter the water before it enters the pipe, reducing the amount of sediment. However, these devices only reduce the amount of sediment; the water still carries sediment and accumulates, causing blockages that are difficult to clear.

[0005] Therefore, there is a need for an inverted siphon type urban sewage pipeline system. Summary of the Invention

[0006] To address the problem of difficult-to-clear blockages in inverted siphon pipes, this application provides an inverted siphon urban sewage pipe system.

[0007] The inverted siphon urban sewage pipeline system provided in this application adopts the following technical solution: An inverted siphon urban sewage pipeline system includes an inverted siphon pipe and a mobile sludge removal device disposed in the inverted siphon pipe; the inverted siphon pipe includes an inlet pipe, an outlet pipe and a flow pipe, one end of the flow pipe is connected to the inlet pipe and the other end is connected to the outlet pipe, and the flow pipe is located below the outlet of the inlet pipe and the outlet of the outlet pipe, a recessed sludge collection part is provided at the connection between the flow pipe and the outlet pipe, and a sludge suction pipe is provided in the sludge collection part, one end of the sludge suction pipe extends out of the inverted siphon pipe and is connected to a negative pressure suction device; the mobile sludge removal device can be placed in the flow pipe, and the mobile sludge removal device includes a movable base and a push plate connected to the movable base, the push plate moves under the drive of the movable base, and can push the sludge in the flow pipe toward the sludge collection part.

[0008] By adopting the above technical solution, regardless of the water flow rate in the inverted siphon pipe, the water flows upward from the inlet pipe to the outlet pipe. This upward flow is insufficient to lift all the sediment to the outlet pipe, easily leading to sediment accumulation and blockage at the connection between the inlet and outlet pipes. Therefore, the sediment collection section is designed to collect the sediment accumulated at the connection between the inlet and outlet pipes, and the collected sediment can be extracted from the inverted siphon pipe through the suction pipe under the action of a negative pressure suction device. Currently, sludge removal and blockage prevention are implemented. Furthermore, when the water flow in the inverted siphon pipe is low, the water can be pumped out through the sludge extraction pipe under the action of a negative pressure suction device, thus maintaining a low liquid level in the water passage pipe. This allows the mobile sludge removal device to be placed into the water passage pipe, where the push plate on the mobile sludge removal device pushes the sludge in the water passage pipe into the sludge collection section. Under the action of the negative pressure suction device, the sludge in the sludge collection section is then extracted through the sludge extraction pipe, thereby achieving the cleaning of the sludge in the inverted siphon pipe.

[0009] Furthermore, the sediment collection section is also provided with an air supply pipe and an air equalization ring. The air equalization ring is located at the bottom of the sediment collection section. The air supply pipe is connected to the air equalization ring, and the air equalization ring is provided with several air equalization holes. The other end of the air supply pipe extends out of the inverted siphon pipe and is connected to the air pump.

[0010] By adopting the above technical solution, air can be pumped into the sediment collection section through an air pump, and under the action of the equalizing ring, air bubbles can be sprayed upward from the bottom of the entire sediment collection section, making it difficult for the mud and water in the sediment collection section to settle, so that the mud and water can be easily extracted from the sludge extraction pipe.

[0011] Furthermore, the movable seat includes a base frame, driven wheels, a top frame, drive wheels, a drive unit, and a lifting unit; the base frame is connected to multiple driven wheels, which can abut against the wall of the water pipe via the driven wheels; the top frame is connected to the drive unit and multiple drive wheels, and the drive wheels are connected to the drive unit so that they can rotate under the drive of the drive unit, and the top frame abuts against the wall of the water pipe via the drive wheels; one end of the lifting unit is connected to the base frame, and the other end of the lifting unit is connected to the top frame, and the lifting unit can drive the top frame to move closer to or away from the base frame.

[0012] By adopting the above technical solution, placing the drive unit on the top frame makes it less likely for the drive unit to come into contact with water, thus preventing damage from water intrusion and ensuring the stability of the mobile dredging device. In addition, the lifting unit can adjust the height of the top frame, ensuring that the drive wheel is always in contact with the closed inverted siphon pipe, so that the mobile dredging device can move and carry out dredging operations.

[0013] Specifically, the base frame includes a pair of bottom longitudinal beams and a pair of bottom transverse beams connected to the pair of bottom longitudinal beams. Each bottom transverse beam has an upwardly bent portion at both ends, and each bent portion is provided with a driven wheel. The driven wheel is loosely fitted on the bent portion and can rotate about the bent portion as an axis.

[0014] By adopting the above technical solution, the driven wheel can better contact the wall of the circular inverted siphon pipe.

[0015] Specifically, the wheel distance between the two driven wheels on the same bottom crossbeam is greater than or equal to half the diameter of the water pipe but less than the diameter of the water pipe.

[0016] By adopting the above technical solution, the driven wheel is less likely to come into contact with the silt at the bottom of the water pipe, thus making the movement of the mobile sludge removal device less affected by the silt at the bottom of the water pipe.

[0017] Specifically, the top frame includes a pair of top longitudinal beams, a pair of top transverse beams connected to the pair of top longitudinal beams, and a pair of rotating shafts; the top transverse beams are located on the top longitudinal beams facing the base frame, and each top transverse beam has bearing seats at both ends extending away from the base frame; the rotating shafts are rotatably connected to the bearing seats, and each end of the rotating shafts is connected to the drive wheel; the drive unit includes a power battery, a drive motor, and a transmission shaft; the power battery and the drive motor are both connected to the top transverse beams; the drive motor is driven by the transmission shaft to drive the transmission shaft to rotate, and the transmission shaft is driven by the rotating shaft to drive the rotating shaft to rotate.

[0018] By adopting the above technical solution, there is no need to power the mobile dredging device through wires, thus eliminating the need for wires and wire receiving / receiving devices, making the structure of the inverted siphon urban sewage pipeline system simpler.

[0019] Specifically, the top frame also includes a waterproof shell, in which a waterproof cavity is formed. The top longitudinal beam, the top transverse beam, the power battery, the drive motor, and the transmission shaft are all located in the waterproof cavity. Both ends of each of the rotating shafts extend out of the waterproof cavity and are connected to the drive wheel. A lip seal is provided between the waterproof shell and the rotating shaft.

[0020] By adopting the above technical solution, the power battery and drive motor can be effectively waterproofed.

[0021] Specifically, the lifting unit includes a lifting driver, a sleeve, and a screw. The lifting driver is located inside the waterproof cavity and connected to the inner wall of the waterproof shell. The sleeve has an internal thread structure. One end of the screw is placed inside the sleeve, and the end of the screw located inside the sleeve has an external thread structure that matches the internal thread structure. The other end of the screw passes through the waterproof shell and is connected to the lifting driver. The lifting driver can drive the screw to rotate.

[0022] By adopting the above technical solution, the lifting and lowering adjustment of the top frame can be achieved.

[0023] Specifically, it also includes a power supply station, which comprises a power generation unit, a power supply electromagnetic resonator, and a power supply chamber. The power supply chamber is connected to the water inlet pipe, and the connection between the power supply chamber and the water inlet pipe is provided with an inlet and outlet for a sludge removal device. The water inlet of the water inlet pipe is located below the inlet and outlet of the sludge removal device. The power supply electromagnetic resonator is located in the power supply chamber, and the drive unit also includes a power receiving electromagnetic resonator, which is electrically connected to the power battery. The power generation unit includes a solar panel and a storage battery, with the solar panel electrically connected to the storage battery and the storage battery electrically connected to the power supply electromagnetic resonator.

[0024] By adopting the above technical solution, energy saving and environmental protection effects are achieved, it is easy to replenish power to the mobile dredging device, and there is no need to install power cords, and therefore no need to install a device for receiving and discharging power cords, making the structure of the inverted siphon urban sewage pipeline system simpler.

[0025] Specifically, the wheel spacing between the two driven wheels on the same bottom crossbeam is greater than or equal to the diameter of the inlet.

[0026] By adopting the above technical solution, it can be ensured that the mobile dredging device can pass through the water inlet and move upward to the power supply room for power supply.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] Regardless of the water flow rate in the inverted siphon pipe, the water flows upwards from the inlet pipe to the outlet pipe. This upward flow is insufficient to carry all the sediment to the outlet pipe, easily leading to sediment accumulation and blockage at the connection between the inlet and outlet pipes. Therefore, the sediment collection section is designed to collect the sediment accumulated at the connection between the inlet and outlet pipes. The collected sediment can then be extracted from the inverted siphon pipe through the suction pipe under negative pressure, thus achieving sludge removal and blockage prevention. Furthermore, when the water flow rate in the inverted siphon pipe is low, the water can be pumped out of the inverted siphon pipe through the sludge suction pipe under the action of the negative pressure suction device, thereby maintaining the liquid level in the water passage pipe at a low level. This allows the mobile sludge removal device to be placed into the water passage pipe, and the push plate on the mobile sludge removal device can push the sludge in the water passage pipe into the sludge collection section. Under the action of the negative pressure suction device, the sludge in the sludge collection section is then pumped out through the sludge suction pipe, thus achieving the cleaning of the sludge in the inverted siphon pipe.

[0038] Figure 1 This is a perspective view of an inverted siphon-type urban sewage pipeline system according to this application. Figure 2 yes Figure 1 A cross-sectional view along the pipe of an inverted siphon-type urban sewage pipeline system, showing the internal structure of the pipe and the mobile dredging device. See also Figure 1 and Figure 2 The inverted siphon urban sewage pipeline system provided in this application includes an inverted siphon pipe 1 and a mobile sludge removal device 2 installed in the inverted siphon pipe 1; wherein, the inverted siphon pipe 1 includes an inlet pipe 11, an outlet pipe 12 and a flow pipe 13, one end of the flow pipe 13 is connected to the inlet pipe 11 and the other end is connected to the outlet pipe 12, and the flow pipe 13 is located below the outlet of the inlet pipe 11 and the outlet of the outlet pipe 12. The inlet pipe 11, the outlet pipe 12 and the flow pipe 13 can all be set as pipes with a circular cross section, thereby making the inlet pipe 11, the outlet pipe 12 and the flow pipe 13 have high structural strength.

[0039] A recessed sludge collection section 14 is provided at the connection between the water supply pipe 13 and the water outlet pipe 12. A sludge suction pipe 15 is provided in the sludge collection section 14. One end of the sludge suction pipe 15 extends out of the inverted siphon pipe 1 and is connected to the negative pressure suction device 3 set on the ground, so that the mud or sludge in the sludge collection section 14 can be sucked out by the negative pressure suction device 3. The mobile sludge removal device 2 can be placed in the water supply pipe 13 and moved in the water supply pipe 13.

[0040] Figure 3 yes Figure 2 A magnified view of region B in the middle, as shown below. Figure 3 As shown, the mobile sludge removal device 2 includes a mobile base and a push plate 22 connected to the mobile base, so that the push plate 22 can move under the drive of the mobile base to push the sludge in the water pipe 13 to the sludge collection section 14 to clean the sludge in the water pipe 13.

[0041] Understandably, regardless of the water flow rate in the inverted siphon pipe 1, the lower-positioned water pipe 13 is a major area for siltation. In particular, the water flows upward from the water pipe 13 to the outlet pipe 12. The upward flow is insufficient to lift all the silt to the outlet pipe 12, making it easier for silt to accumulate and cause blockage at the connection between the water pipe 13 and the outlet pipe 12. Therefore, the design of the silt collection section 14 can collect the silt accumulated at the connection between the water pipe 13 and the outlet pipe 12, and the collected silt can be extracted from the inverted siphon pipe 1 through the silt extraction pipe 15 under the action of the negative pressure suction device 3, so as to achieve silt removal and blockage prevention.

[0042] Furthermore, when the water flow rate in the inverted siphon pipe 1 is low, the water can be drawn out of the inverted siphon pipe 1 through the sludge suction pipe 15 under the action of the negative pressure suction device 3, thereby keeping the liquid level in the water passage pipe 13 at a low level, so that the mobile sludge removal device 2 can be placed into the water passage pipe 13. Then, the sludge in the water passage pipe 13 can be pushed into the sludge collection section 14 by the push plate 22 on the mobile sludge removal device 2, and the sludge in the sludge collection section 14 can be drawn out through the sludge suction pipe 15 under the action of the negative pressure suction device 3, thereby realizing the cleaning of sludge in the inverted siphon pipe 1.

[0043] Figure 4 yes Figure 2 Enlarged view of region A in the middle. Figure 5 yes Figure 3 A cross-sectional view along the EE direction, such as Figure 4 and Figure 5 As shown, in order to facilitate the suction of mud from the sediment collection section 14, an air supply pipe 16 and an air equalization ring 17 can be installed in the sediment collection section 14. The air equalization ring 17 is located at the bottom of the sediment collection section 14, and the air supply pipe 16 is connected to the air equalization ring 17. The air equalization ring 17 is provided with several air equalization holes 171. The other end of the air supply pipe 16 extends out of the inverted siphon pipe 1 and is connected to the air pump 18, so that air can be blown into the sediment collection section 14 by the air pump 18. Under the action of the air equalization ring 17, air bubbles can be sprayed upward from the bottom of the entire sediment collection section 14, so that the mud in the sediment collection section 14 is not easy to settle, thus making it easier to extract the mud from the suction pipe 15.

[0044] like Figure 3As shown, the movable base includes a base frame 211, driven wheels 212, a top frame 213, drive wheels 214, a drive unit 215, and a lifting unit 216. Specifically, the base frame 211 is connected to multiple driven wheels 212, which can abut against the wall of the water pipe 13 via the driven wheels 212. The top frame 213 is connected to the drive unit 215 and multiple drive wheels 214, and the drive wheels 214 are tractively connected to the drive unit 215 so that they can rotate under the drive of the drive unit 215. The top frame 213 is connected to the water pipe 13 via the drive wheels 214. The pipe wall of pipe 13 abuts against the wall; one end of lifting unit 216 is connected to base frame 211, and the other end of lifting unit 216 is connected to top frame 213. Lifting unit 216 can drive top frame 213 to move closer to or away from base frame 211. When top frame 213 moves away from base frame 211, drive wheel 214 connected to top frame 213 can abut against the pipe wall of water pipe 13. Then, drive wheel 214 driven by drive unit 215 rotates to realize the movement of the moving seat in inverted siphon pipe 1, thereby enabling the sludge to be pushed for dredging operations.

[0045] In addition, it is understood that the drive wheel 214 can be set as a rubber wheel, so that the drive wheel 214 has a certain elastic deformation capability, thereby increasing the friction by increasing the contact area between the drive wheel 214 and the pipe wall of the water pipe 13 or increasing the contact force between the two, so as to ensure that the mobile sludge removal device 2 is not prone to slipping when moving in the inverted siphon pipe 1.

[0046] By mounting the drive unit 215 on the top frame 213, the drive unit 215 is less likely to come into contact with water, thus preventing damage from water intrusion and ensuring the stability of the mobile dredging device 2. In addition, the lifting unit 216 can adjust the height of the top frame 213, ensuring that the drive wheel 214 is always in contact with the wall of the inverted siphon pipe 1, so that the mobile dredging device 2 can move and carry out dredging operations.

[0047] Figure 6 yes Figure 5 A cross-sectional view along the FF direction, such as Figure 3 and Figure 6As shown, the base frame 211 is configured to include a pair of bottom longitudinal beams 2111 and a pair of bottom transverse beams 2112 connected to the pair of bottom longitudinal beams 2111. Each bottom transverse beam 2112 has an upwardly bent portion 21121 at both ends. Each bent portion 21121 is provided with a driven wheel 212. The driven wheel 212 is loosely fitted on the bent portion 21121 and can rotate about the bent portion 21121 as an axis. The wheel distance between the two driven wheels 212 on the same bottom transverse beam 2112 is greater than or equal to half the diameter of the water pipe 13 and less than the diameter of the water pipe 13. The above design allows the driven wheel 212 to be perpendicular to the wall of the circular inverted siphon pipe 1 after it comes into contact with the pipe wall. This makes the driven wheel 212 less prone to bending and damage. Furthermore, the wheel spacing makes it less likely for the driven wheel 212 to come into contact with the silt at the bottom of the water pipe 13. This makes the movement of the mobile sludge removal device 2 less affected by the silt at the bottom of the water pipe 13.

[0048] See Figure 3 Specifically, the top frame 213 may be configured to include a pair of top longitudinal beams 2131, a pair of top transverse beams 2132 connected to the pair of top longitudinal beams 2131, and a pair of rotating shafts 2133; wherein, the top transverse beams 2132 may be provided on the side of the top longitudinal beams 2131 facing the base frame 211, and each top transverse beam 2132 has bearing seats 21321 extending away from the base frame 211 at both ends, the rotating shafts 2133 are rotatably connected to the bearing seats 21321, and each rotating shaft 2133 has a drive wheel 214 connected to both ends; the drive unit 215 may be configured to include a power battery 2151 and a drive motor 21 52 and drive shaft 2153, wherein the power battery 2151 and drive motor 2152 can both be connected to the top crossbeam 2132. The drive motor 2152 is connected to the drive shaft 2153 to drive the drive shaft 2153 to rotate, and the drive shaft 2153 is connected to the rotating shaft 2133 to drive the rotating shaft 2133 to rotate, thereby realizing the movement of the mobile sludge removal device 2. The power battery 2151 can power the mobile sludge removal device 2 without the need for wires, thus eliminating the need for wires and wire receiving / receiving devices, making the structure of the inverted siphon urban sewage pipeline system simpler.

[0049] It is understandable that, such as Figure 3As shown, the top frame 213 should also include a waterproof shell 2134, within which a waterproof cavity is formed. The top longitudinal beam 2131, top transverse beam 2132, power battery 2151, drive motor 2152, and drive shaft 2153 are all housed within the waterproof cavity. Both ends of each rotating shaft 2133 extend from the waterproof cavity and connect to the drive wheel 214. A lip seal is provided between the waterproof shell 2134 and the rotating shaft 2133. A transmission bearing seat 21341 for connecting to the drive shaft 2153 can be provided within the waterproof shell 2134. Effective waterproof protection is provided for the power battery 2151 and the drive motor 2152; the output shaft of the drive motor 2152 passes through the top crossbeam 2132 and is connected to the transmission shaft 2153. A matching bevel gear can be provided between the output shaft of the drive motor 2152 and the transmission shaft 2153 to realize the transmission connection between the two. A matching bevel gear can also be provided at the connection between the transmission shaft 2153 and each rotating shaft 2133, so as to realize the transmission connection between the transmission shaft 2153 and each rotating shaft 2133, thereby realizing the rotation of the drive wheel 214.

[0050] See Figure 3 and Figure 6 The lifting unit 216 includes a lifting driver 2161, a sleeve 2162, and a screw 2163. The lifting driver 2161 (which may be a motor) is located in the waterproof accommodating cavity and can be connected to the inner wall of the waterproof shell 2134 through a connecting frame. The sleeve 2162 has an internal thread structure. One end of the screw 2163 is placed inside the sleeve 2162, and this end has an external thread structure that matches the internal thread structure of the sleeve 2162. The lifting driver 2161 is connected to the connecting frame, and the connecting frame has a through hole structure. The other end of the screw 2163 can pass through the waterproof shell 2134 and the through hole structure on the connecting frame and connect to the lifting driver 2161, so that the lifting driver 2161 can drive the screw 2163 to rotate, thereby realizing the lifting and adjustment of the top frame 213.

[0051] Figure 7 yes Figure 2 Enlarged view of region C in the middle. Figure 8 yes Figure 2 See the enlarged view of region D in the middle. Figure 7 and Figure 8 The inverted siphon urban sewage pipeline system of this application also includes a power supply station 4, which includes a power generation unit 41, a power supply electromagnetic resonator 42, and a power supply chamber 43. The power supply chamber 43 is connected to the inlet pipe 11, and a sludge removal device inlet / outlet 111 is provided at the connection between the power supply chamber 43 and the inlet pipe 11. The inlet 112 of the inlet pipe 11 is located below the sludge removal device inlet / outlet 111. The power supply electromagnetic resonator 42 is located inside the power supply chamber 43, and as... Figure 3As shown, the drive unit 215 also includes a powered electromagnetic resonator 2154, which is electrically connected to the power battery 2151; the power generation unit 41 includes a solar panel 411 and a battery 412, which are electrically connected to each other, and the battery 412 is electrically connected to the power supply electromagnetic resonator 42.

[0052] The mobile sludge removal device can move upward along the water inlet pipe 11 and enter the power supply chamber 43 through the sludge removal device inlet and outlet 111. Before the inverted siphon pipe 1 operates at full power, the mobile sludge removal device 2 needs to return to the power supply chamber 43. Since the water inlet 112 of the water inlet pipe 11 is below the sludge removal device inlet and outlet 111, water flow is difficult to penetrate into the power supply chamber 43, thus ensuring that the power supply electromagnetic resonator 42 is not damaged. After the mobile sludge removal device 2 returns to the power supply chamber 43, the receiving electromagnetic resonator 2154 can match the power supply electromagnetic resonator 42 to wirelessly charge the power battery 2151. The receiving electromagnetic resonator 2154 and the power supply electromagnetic resonator 42 are existing wireless power transmission technologies, which will not be described in detail here.

[0053] In addition, it is understood that the wheel distance between the two driven wheels 212 on the same bottom crossbeam 2112 is greater than or equal to the diameter of the inlet 112, so as to ensure that the mobile dredging device 2 can pass through the inlet 112 and move upward to the power supply chamber 43 for power supply.

[0054] The working principle of an inverted siphon-type urban sewage pipeline system disclosed in this application is as follows:

[0055] When water flows from the inlet pipe 13 to the outlet pipe 12, it rises. This rising water flow is insufficient to lift all the sediment to the outlet pipe 12, easily leading to sediment accumulation and blockage at the connection between the inlet pipe 13 and the outlet pipe 12. Therefore, the sediment collection section 14 is designed to collect the sediment accumulated at the connection between the inlet pipe 13 and the outlet pipe 12. The collected sediment can be extracted from the inverted siphon pipe 1 through the suction pipe 15 under the action of the negative pressure suction device 3, thus achieving sludge removal and blockage prevention. Furthermore, in the inverted siphon pipe... When the water flow rate in 1 is low, the water in the inverted siphon pipe 1 can be pumped out through the sludge suction pipe 15 under the action of the negative pressure suction device 3, so that the liquid level in the water passage pipe 13 is maintained at a low level, so that the mobile sludge removal device 2 can be put into the water passage pipe 13. The sludge in the water passage pipe 13 can be pushed into the sludge collection section 14 by the push plate 22 on the mobile sludge removal device 2, and the sludge in the sludge collection section 14 can be pumped out through the sludge suction pipe 15 under the action of the negative pressure suction device 3, thereby realizing the cleaning of sludge in the inverted siphon pipe 1.

[0056] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
