Technical Field

[0001] This utility model relates to the field of sewage pumping station technology, and more specifically, to an intelligent sewage pumping station that is easy to ventilate. Background Technology

[0002] Wastewater pumping stations are an important component of wastewater systems. They are pumping stations installed within the wastewater pipeline system to pump up urban wastewater. Their main function is to lift and transport wastewater, ensuring that it can flow smoothly from lower to higher elevations or be transported over long distances to wastewater treatment plants for processing.

[0003] During the maintenance of sewage pumping stations, toxic gases often accumulate inside. To ensure the safety of maintenance personnel, exhaust fans are usually installed inside the pumping station to quickly expel these harmful gases from the pump body. However, these fans may experience various malfunctions during prolonged operation. If a fan fails, the toxic gases inside the pumping station cannot be expelled in a timely manner, delaying the fan's maintenance progress and consequently affecting the normal maintenance and operation of the entire sewage pumping station. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1-6 As shown, an intelligent sewage pumping station with easy ventilation includes a cylinder 1, a sealing cover 8, a hinge assembly, a ventilation assembly, and a drive assembly; the cylinder 1 has a through hole 2 on its side wall, and the inner side wall of the through hole 2 has symmetrically opened limit grooves 3; the sealing cover 8 is slidably connected to the inner wall of the through hole 2, and its outer side has a protrusion that cooperates with the limit groove 3.

[0029] The hinge assembly includes a hinge seat 9 fixed to the outer wall of the sealing cover 8 and a rotating shaft 13 fixedly connected to the hinge seat 9;

[0030] The ventilation assembly includes a housing 4 fixedly connected to the inner wall of the cylinder 1. The housing 4 is positioned facing the through hole 2. A fan 5 is fixedly installed on the inner wall of the housing 4. The exhaust end of the fan 5 is connected to an exhaust pipe 6 that passes through the housing 4 and the cylinder 1, and the intake end is connected to an intake pipe 7 that extends into the cylinder 1. Through the intelligent control system, the operating parameters of the fan 5 can be automatically adjusted according to the real-time monitoring data of the air quality inside the cylinder 1 to ensure that the ventilation effect is always at its best.

[0031] The drive assembly includes a bracket 10 fixed to the outer wall of the cylinder 1, a threaded sleeve 12 rotatably connected to the bracket 10, a screw 11 threadedly engaged with the threaded sleeve 12, and a rotating handle 14 fixedly installed at the end of the screw 11. The end of the screw 11 is rotatably connected to the rotating shaft 13. The electrical control cabinet 18 starts the fan 5, which draws out polluted air from inside the cylinder through the suction pipe 7 and discharges it to the outside through the exhaust pipe 6.

[0032] like Figure 3 As shown, a limiting plate 15 is fixedly connected to the outer wall of the cylinder 1. The limiting plate 15 is used to limit the sealing cover 8.

[0033] like Figure 1 As shown, the top of the cylinder 1 is equipped with an inspection port 17, the side wall with a water inlet 16, and the top outer surface with an electrical control cabinet 18, which is electrically connected to the blower 5. The electrical control cabinet 18 is the core control unit of the intelligent sewage pumping station, integrating a PLC and an intelligent communication module. It can collect various operating data of the pumping station in real time, such as liquid level, flow rate, pressure, and equipment status, and upload this data to the remote monitoring center. At the same time, it can also receive control commands issued by the remote monitoring center to realize remote control and intelligent scheduling of the pumping station equipment.

[0034] External sewage flows into the cylinder through the inlet 16 on the side wall of the cylinder 1. The sewage is temporarily stored at the bottom of the cylinder 1 and impurities are settled. Multiple liquid level sensors are installed inside the cylinder 1 to monitor the liquid level in the cylinder 1 in real time. When the liquid level reaches the set threshold, the electrical control cabinet 18 starts the vertical submersible pump 23. The vertical submersible pump 23 pressurizes and discharges the sewage through the pressure pipe 25. The water flows through the gate valve 26 and the check valve 27 in sequence, and finally is discharged to the external pipe network through the drain pipe 28.

[0035] like Figure 2 As shown, a vertically extending maintenance platform 20 is provided inside the cylinder 1, and a ladder 19 is connected between the maintenance platform 20 and the inspection port 17. Operators enter through the top inspection port 17, climb the ladder 19 to reach the maintenance platform 20, and complete the equipment inspection.

[0036] In some embodiments, the intelligent sewage pumping station is also equipped with a fault early warning function. When the equipment malfunctions or becomes abnormal, the electrical control cabinet 18 can promptly issue an alarm signal and upload the fault information to the remote monitoring center to notify maintenance personnel to handle the situation in a timely manner.

The drainage system includes multiple pressure pipes 25 connected to the outlet of a vertical submersible pump 23, a drain pipe 28 fixedly installed on the outer end of the pressure pipes 25, and a check valve 27 and a gate valve 26 sequentially installed on the pressure pipes 25 along the water flow direction. The end of the pressure pipe 25 passes through the cylinder 1 and extends to its outer side. A coupling device 24 is fixedly installed on the bottom of the inner wall of the cylinder 1. The vertical submersible pump 23 is detachably connected to the coupling device 24 through a coupling flange. The pressure pipe 25 is connected to the base of the coupling device 24. Multiple pump guide rails 21 extending to the bottom of the cylinder 1 are installed on the inner wall of the maintenance platform 20. A fixing bracket 22 for fixing the vertical submersible pump 23 is fixedly installed on the sliding part of the pump guide rail 21.

[0038] The submersible pump 23 is mounted on the pump guide rail 21 via the mounting bracket 22. During maintenance, it is raised along the pump guide rail 21 to the height of the maintenance platform 20.

[0039] A coupling flange is located at one end of the vertical submersible pump, and an annular groove is opened on the coupling flange, and a soft sealing gasket is tightly fixed thereon; the coupling device 24 includes a base, which is installed in the sump, and the inlet flange of the base has an annular groove that matches the coupling flange, and is equipped with a soft sealing gasket for tight fit with the coupling flange; the pump guide rail 21 guides the installation and removal of the vertical submersible pump 23; when the vertical submersible pump 23 slides down the pump guide rail 21 and couples with the base, the outlet of the vertical submersible pump 23 automatically connects with the pressure pipe 25.

[0040] Working principle: Rotating the rotating handle 14 drives the screw 11 to rotate, and the screw 11 moves spirally along the threaded sleeve 12. The screw 11 drives the hinge seat 9 to move through the rotating shaft 13, and the hinge seat 9 drives the sealing cover 8 to slide outward along the inner wall of the through hole 2. At this time, the screw 11 drives the threaded sleeve 12 to rotate, and with the movement of the sealing cover 8, the sealing cover 8 can be moved out of the cylinder 1. At this time, the operator can inspect the fan 5 in the casing 4 through the through hole 2.

[0041] Continue to rotate screw 11 to move sealing cover 8 to the position where cylinder 1 is below through hole 2, so that operators can easily carry out maintenance;

[0042] After maintenance, rotate screw 11 in the reverse direction to make the sealing cover 8 slide upward along the cylinder 1 to the limiting plate 15. At this time, due to the restriction of the limiting plate 15, rotating screw 11 can push the sealing cover 8 into the through hole 2 for sealing installation.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
