Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering pump station technology, and in particular to a submersible pump lifting device for underground water conservancy pump stations. Background Technology

[0002] Submersible pumps, as core devices in water pumping stations, play a crucial role in deep well water intake, farmland irrigation, and the delivery of drinking water for residents. However, since submersible pumps operate underwater, they must be submerged for use. Traditional methods, such as manual shallow-lifting or crane hoisting, generally suffer from problems such as wasted labor, high equipment failure rates, insufficient mechanization and automation, and swaying during submersible pump descent affecting normal operation. Therefore, with technological advancements, achieving labor-saving and stable operation during the submersible pump lifting process has become a key focus of research on lifting devices.

[0003] Existing underground pumping stations, as shown in the publication CN215595651U, entitled "A Drainage System for a Vertical Shaft Working Face," have the following problems:

[0004] 1. There is only one submersible pump, which cannot achieve the "one-use-multiple-backup" situation. It cannot be used during maintenance and cannot meet the high flow rate requirements in special situations.

[0005] 2. The submersible pump is lifted by the motor driving the cable to bend. Under the impact of the water flow in the underground layer of the pumping station, it is prone to instability and collision with the inner wall, which may cause damage to the pump or cause it to fall off in the event of shaking, resulting in unstable lifting.

[0006] 3. The device's diving depth and pump flow rate cannot be controlled, and it is inconvenient to maintain. Overall, its self-control and ease of use are poor.

[0007] 4. The lack of a filter device can easily cause the pump inlet to become clogged and burn out the pump. Utility Model Content

[0008] This utility model provides a submersible pump lifting device for underground water pumping stations, aiming to solve the problems mentioned above, such as the lack of "one-use-multiple-backup" capability, unstable lifting, poor self-control and ease of use, and lack of filtration devices in existing pumping stations.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A submersible pump lifting device for an underground pumping station includes an underground pumping station, which has an above-ground layer and an underground layer. The above-ground layer is equipped with a measurement system for monitoring pump flow and pumping station liquid level, and a control panel is provided on one side of the measurement system.

[0011] The underground level is equipped with several underground pump modules. Each underground pump module includes a submersible pump that is telescopically connected to the bottom of the underground level through a lifting mechanism. Several inclined supports are provided between the lifting mechanism and the top of the underground level. Lifting cages are provided on the outside of each submersible pump. A corresponding maintenance platform is provided on one side of each submersible pump. The above-ground level is connected to the maintenance platform through a platform ladder.

[0012] Preferably, the measurement system includes a water supply pipe installed on the ground floor, the outlet of the submersible pump is connected to the telescopic pipe through a reducing pipe, the other end of the telescopic pipe is connected to the water supply pipe through a conversion joint, and a flow meter is installed on the side of the water supply pipe near the outlet.

[0013] More preferably, the measurement system also includes a level gauge with the gauge head located on the ground floor and the level gauge probe extending vertically downwards into the underground floor.

[0014] Furthermore, the flow meter, level gauge, submersible pump, and lifting mechanism are all electrically connected to the control panel.

[0015] Preferably, there are at least two underground pump modules, and the two underground pump modules are arranged symmetrically about the middle position of the underground layer.

[0016] More preferably, the lifting mechanism includes a vertically arranged hydraulic telescopic rod, which is driven by a hydraulic rod drive motor on one side. The fixed part of the hydraulic telescopic rod is detachably fixed to the top of the underground floor by bolts, and the output part of the hydraulic telescopic rod is fixedly installed with a lifting section. The top of the submersible pump is suspended and installed on the lifting section by a lifting ring.

[0017] Furthermore, the diagonal supports are arranged in pairs and are symmetrical about the intermediate axis of the hydraulic telescopic rod.

[0018] Furthermore, the hydraulic telescopic rod is provided with a first docking part on the side near the fixed part, and a second docking part corresponding to the first docking part is provided at the top of the underground layer. One end of the inclined support is fixedly installed with the first docking part by a fastening pin, and the other end of the inclined support is fixedly installed with the second docking part by a fastening pin.

[0019] Preferably, the lifting cage is a hollow cubic basket structure, the submersible pump is embedded in the middle of the lifting cage, and a lifting basket frame is provided at the top opening of the lifting cage. The two ends of the lifting basket frame are respectively fixed to the top middle positions of the opposite sides of the lifting cage, and the lifting basket frame passes through the lifting section and forms a fixed suspension connection with the lifting section.

[0020] More preferably, there are two basket frames, both of which are arranged horizontally and are perpendicular to each other in the vertical direction and overlap in the middle of the lifting cage. The two basket frames pass through the lifting section along their respective arrangement directions, and the through holes are perpendicular to each other and overlap. The two basket frames and the lifting section form a limiting and fixing fit.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model has a simple structure, and multiple underground pump modules can form a "one-use-multiple-backup" situation. When one of them fails or needs maintenance, other underground pump modules can be started to ensure the continuous operation of the pumping station. They can be alternately maintained, and multiple pumps can be used at the same time to cope with ultra-large flow demand in special circumstances.

[0023] 2. The lifting mechanism allows for free setting of the submersible pump's lifting height. The inclined support improves the installation stability of the lifting mechanism, reduces the impact of water flow, and ensures a smooth and reliable pump lifting process. The cage structure of the lifting cage can create a relatively stable working environment, reducing the impact of water flow and buoyancy, and also serves as a safety structure to prevent the submersible pump from falling.

[0024] 3. The measurement system can monitor the flow rate of the submersible pump and the water level of the underground pumping station in real time. It is easy to install and can be controlled locally and remotely through the control panel. It also has the functions of monitoring the pumping station liquid level and flow rate. It is equipped with a maintenance platform for convenient maintenance and repair.

[0025] 4. At the same time, the basket-shaped hollow structure of the lifting cage can also act as a filter screen to reduce clogging at the pump inlet. Attached Figure Description

[0028] The embodiments will be further described below with reference to the accompanying drawings.

[0029] like Figure 1As shown in the preferred embodiment 1, a submersible pump lifting device for an underground pumping station includes an underground pumping station. The underground pumping station has an above-ground layer and an underground layer. The above-ground layer is equipped with a measurement system 17 for monitoring pump flow and pumping station liquid level. A control panel 9 is provided on one side of the measurement system 17.

[0030] The underground level is equipped with several underground pump modules. Each underground pump module includes a submersible pump 16 that is telescopically connected to the bottom of the underground level through a lifting mechanism 13. Several inclined supports 20 are provided between the lifting mechanism 13 and the top of the underground level. Lifting cages 19 are provided on the outside of each submersible pump 16. A corresponding maintenance platform 11 is provided on one side of each submersible pump 16. The above-ground level is connected to the maintenance platform 11 through a platform ladder 10.

[0031] The arrangement of the platform ladder 10 facilitates maintenance personnel to reach the maintenance platform 11 to perform daily maintenance and troubleshooting on the pump and lifting mechanism 13. The maintenance platform 11 is also equipped with railings to prevent personnel from slipping off the platform and ensure their safety.

[0032] This lifting device has a simple structure, and multiple underground pump modules can form a "one-use-multiple-backup" configuration. When one module fails or needs maintenance, other underground pump modules can be started to ensure the continuous operation of the pumping station. Alternating maintenance is also possible, and simultaneous operation of multiple pumps can handle ultra-high flow demands in special circumstances. The measurement system 17 can monitor the flow rate of the submersible pump 16 and the water level in the underground layer of the pumping station in real time. Installation is convenient, and the control panel 9 enables local and remote control, while also providing pumping station level and flow monitoring functions. A maintenance platform 11 is provided for convenient maintenance and repair. The lifting mechanism 13 allows for free setting of the lifting height of the submersible pump 16. The inclined support 20 improves the installation stability of the lifting mechanism 13, reducing the impact of water flow and ensuring a smooth and reliable pump lifting process. The lifting cage 19's cage structure creates a relatively stable working environment, reducing the impact of water flow and buoyancy, and also serves as a safety structure to prevent the submersible pump 16 from falling. The basket-shaped perforated structure of the lifting cage 19 also acts as a filter, reducing clogging at the pump inlet.

[0033] As a preferred embodiment 2, the measurement system 17 includes a water supply pipe 8 located on the ground floor. The outlet of the submersible pump 16 is connected to the telescopic pipe 12 via a reducer 18. The other end of the telescopic pipe 12 is connected to the water supply pipe 8 via a conversion joint 6. A flow meter 5 is provided on the side of the water supply pipe 8 near the outlet. The telescopic pipe 12 can be a corrugated pipe to accommodate the height changes of the submersible pump 16. The water drawn by the submersible pump 16 is transported through the reducer 18, the telescopic pipe 12, and the conversion joint 6 in sequence into the water supply pipe 8. During the transportation process, the flow rate data delivered by the pump is measured in real time by the flow meter 5.

[0034] In a preferred embodiment 3, the measurement system 17 also includes a level gauge, with the level gauge head 7 located on the ground floor and the level gauge probe 1 extending vertically downwards into the underground floor. The level gauge allows for real-time measurement of the liquid level data within the pumping station, which can be displayed in real-time or connected to the control panel 9 for display.

[0035] In a preferred embodiment 4, the flow meter 5, level gauge, submersible pump 16, and lifting mechanism 13 are all electrically connected to the control panel 9. The control panel 9 can display the pump flow rate, station level, and submersible pump operating status, and can be controlled locally or remotely on the ground floor.

[0036] In a preferred embodiment 5, there are at least two underground pump modules, and the two underground pump modules are symmetrically arranged about the middle position of the underground layer. This ensures at least one module in use and one in standby, guaranteeing continuous operation while ensuring the structural stability of the pump station.

[0037] In a preferred embodiment 6, the lifting mechanism 13 includes a vertically arranged hydraulic telescopic rod 2. The hydraulic telescopic rod 2 is driven by a corresponding hydraulic rod drive motor 3 on one side. The fixed part of the hydraulic telescopic rod 2 is detachably fixed to the top of the underground floor by bolts 4. The output part of the hydraulic telescopic rod 2 is fixedly installed with a lifting section 14. The top of the submersible pump 16 is suspended and installed on the lifting section 14 by a lifting ring 15. The lifting mechanism 13 is the core of this device. It adopts the existing hydraulic lifting rod mechanism, which is more stable in operation. The hydraulic telescopic rod 2 is driven to extend and retract by the hydraulic rod drive motor 3, which has a larger lifting torque, supports the lifting of large submersible pumps, is safe and stable in operation, and has fewer parts, which greatly reduces the failure rate.

[0038] The hydraulic drive motor and hydraulic rod are fixed to the top of the pump house by pre-embedded anchor bolts, which is simple to install. The hydraulic drive motor and hydraulic rod can adapt to the long-term underwater operation environment and there is no risk of leakage.

[0039] The lifting section 14 is a columnar metal assembly installed at the end of the telescopic rod for hoisting the submersible pump 16 and the lifting cage 19.

[0040] Preferably, a liquid level sensor can be installed on the top of the submersible pump 16 to monitor the pump's submersion depth.

[0041] In a preferred embodiment 7, the diagonal supports 20 are arranged in pairs and symmetrical about the central axis of the hydraulic telescopic rod 2. This ensures the stability of the hydraulic telescopic rod 2 under stress and guarantees the stability of the supports after they are fixed.

[0042] The hydraulic telescopic rod 2 has a first connecting piece near the fixed part, and a second connecting piece corresponding to the first connecting piece is provided at the top of the underground floor. One end of the inclined support 20 is fixedly installed with the first connecting piece by a fastening pin 21, and the other end of the inclined support 20 is fixedly installed with the second connecting piece by a fastening pin 21. Using the existing pin fastening structure, the installation structure of the fastening pin 21 can achieve a stable connection between the inclined support 20 and the hydraulic rod, and can also achieve quick disassembly for inspection and maintenance.

[0043] In a preferred embodiment 8, the lifting cage 19 is a hollow cubic basket-shaped structure. The submersible pump 16 is embedded in the middle of the lifting cage 19. A basket frame is provided at the top opening of the lifting cage 19. The two ends of the basket frame are respectively fixed to the top middle positions of opposite sides of the lifting cage 19. The basket frame passes through the lifting section 14 and forms a fixed suspension connection with the lifting section 14. The lower part of the round steel suspension structure of the lifting cage 19 is a square three-dimensional structure, and a stainless steel square hole filter screen is installed on the surface of the structure. The hollow basket-shaped stainless steel square hole filter screen structure of the lifting cage 19 can reduce the impact of water flow and prevent the suction inlet of the submersible pump 16 from being blocked by debris, thereby further ensuring the safe operation of the submersible pump and preventing it from being burned out.

[0044] In a more preferred embodiment 9, there are two basket frames, both horizontally arranged and vertically overlapping in the middle of the lifting cage 19. Each basket frame passes through the lifting section 14 along its corresponding direction, with the through holes perpendicular and overlapping. The two basket frames and the lifting section 14 form a limiting and fixing fit. At this time, the lifting section 14 is exactly located in the middle of the lifting cage 19. Through the double basket frame structure, which is both perpendicular and horizontally arranged, the two basket frames can form a cross shape with the lifting section 14 to limit and fix them, ensuring secure hoisting.

[0045] Preferably, the basket frame includes a horizontally arranged steel pipe that penetrates and limits the lifting section 14. Connecting steel is welded to both ends of the steel pipe, and the vertical connecting steel is welded and fixed to the top middle position of the corresponding two sides of the lifting cage 19.

[0046] Preferably, the position of the basket frame penetrating the lifting section 14 is located above the position of the lifting ring 15, which avoids conflict between the installation of the cage and the pump and facilitates installation.

[0047] The working principle of this utility model:

[0048] This lifting device has a simple structure, and multiple underground pump modules can form a "one-use-multiple-backup" configuration. When one module fails or needs maintenance, other underground pump modules can be started to ensure the continuous operation of the pumping station. Alternating maintenance is also possible, and simultaneous operation of multiple pumps can handle ultra-high flow demands in special circumstances. The measurement system 17 can monitor the flow rate of the submersible pump 16 and the water level in the underground layer of the pumping station in real time. Installation is convenient, and the control panel 9 enables local and remote control, while also providing pumping station level and flow monitoring functions. A maintenance platform 11 is provided for convenient maintenance and repair. The lifting mechanism 13 allows for free setting of the lifting height of the submersible pump 16. The inclined support 20 improves the installation stability of the lifting mechanism 13, reducing the impact of water flow and ensuring a smooth and reliable pump lifting process. The lifting cage 19's cage structure creates a relatively stable working environment, reducing the impact of water flow and buoyancy, and also serves as a safety structure to prevent the submersible pump 16 from falling. The basket-shaped perforated structure of the lifting cage 19 also acts as a filter, reducing clogging at the pump inlet.
