Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment, and in particular to a shock-absorbing water pump for water diversion engineering pumping stations. Background Technology

[0002] With the development of vibration-damping pumps for water diversion projects, more and more vibration-damping pumps are being used in fixed pumping stations of large-scale inter-basin water diversion projects, small and medium-sized pumping stations for regional water resource allocation, and mobile pumping stations for flood drainage. Reasonable use can protect equipment and engineering structures, extend service life, reduce noise pollution, meet environmental protection and human needs, ensure operational stability, and improve water diversion efficiency.

[0003] The water pumps commonly used in existing water diversion project pumping stations mainly consist of a pump body, impeller, pump shaft, and drive motor. The motor is connected to the pump shaft through a coupling, driving the pump shaft to rotate the impeller at high speed within the pump body, enabling the fluid to gain kinetic and potential energy, thereby achieving the water conveyance function. To reduce vibration, components such as rubber damping pads or spring dampers are often used. Rubber damping pads absorb the vibration energy generated during pump operation through their own elastic deformation, while spring dampers rely on the elastic expansion and contraction of springs to buffer the vibration transmitted by the pump, thereby weakening the transmission of vibration.

[0004] Existing vibration-damping pumps used in water diversion projects typically employ internal spring structures for vibration reduction. However, these structures have limitations in vibration reduction capabilities, including insufficient coverage of complex vibrations, limited noise control, inadequate environmental friendliness, complex installation and maintenance, and low efficiency. Therefore, a vibration-damping pump for water diversion projects is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibration-damping water pump for water diversion engineering pumping stations, aiming to improve the problems of insufficient vibration coverage, limited noise control capabilities, and complex installation in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A shock-absorbing water pump for a water diversion project pumping station includes a housing, a base fixedly connected to the top of the housing, a motor mounted on the top of the base, and a transmission assembly mounted on the drive end of the motor. The transmission assembly includes a sleeve 1, which is rotatably connected to the outer wall of the motor. A fixing plate 1 is fixedly connected to the top of the sleeve 1, a connecting plate 1 is fixedly connected to the top of the fixing plate 1, a fixing plate 2 is fixedly connected to the top of the connecting plate 1, and a sleeve 2 is fixedly connected to the top of the fixing plate 2. A guide post 1 is fixedly connected inside the connecting plate 1, a gasket 1 is fixedly connected to the outer wall of the guide post 1, a gasket 2 is fixedly connected to the outer wall of the guide post 1, and a spring is provided on the outer wall of the guide post 1. One end of the spring is fixedly connected to one end of the gasket 1, and the other end of the spring is fixedly connected to one end of the gasket 2.

[0007] As a further description of the above technical solution: A fixing column is fixedly connected to the top of the outer shell.

[0008] As a further description of the above technical solution: The base is equipped with a pump body on top.

[0009] As a further description of the above technical solution: The pump body is fixedly connected to an inner flange interface, and a bellows is fixedly connected to the outer wall of the inner flange interface.

[0010] As a further description of the above technical solution: Flange 2 is fixedly connected to the top of the corrugated pipe, and flange 1 is fixedly connected to the bottom of the corrugated pipe.

[0011] As a further description of the above technical solution: A second connecting plate is fixedly connected to the outer wall of flange one, and a third connecting plate is fixedly connected to the outer wall of flange two.

[0012] As a further description of the above technical solution: The connecting plate three is internally threaded with a guide post two, and the outer wall of the guide post two is threaded with a bolt.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the elastic deformation of the spring buffers the vibration, enabling the connection between the first fixed plate and the second fixed plate to have shock absorption capability. With the cooperation of components such as the ball and guide column, the coupling can absorb axial and radial offset when transmitting torque, achieving the effect of buffering and shock absorption. This improves the stability of the coupling operation and its adaptability to different installation errors, and solves the problem that traditional couplings are easily damaged by vibration or displacement due to rigid connection.

[0014] 2. In this utility model, the corrugated pipe absorbs the radial and axial vibrations and displacements generated during the operation of the water pump and the pipeline by utilizing the corrugated elastic deformation characteristics. At the same time, the use of bolts, adjusting screws and other components to assist in fixing ensures the accuracy and stability of the connection between the pipeline and the water pump. This achieves the effect of flexibly compensating for pipeline deformation, shock absorption and leak prevention, and improves the adaptability and reliability of pipeline connection. It also solves the problem that traditional rigid pipeline connections are prone to interface leakage and pipeline damage due to vibration or thermal expansion and contraction.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a shock-absorbing water pump for a water diversion project pumping station, including a housing 1, characterized in that: a base 3 is fixedly connected to the top of the housing 1, a motor 4 is provided on the top of the base 3, the motor 4 converts electrical energy into mechanical energy, drives the pump body 5 to rotate, provides power for the operation of the pump body 5, and ensures the water conveying efficiency of the water diversion project pumping station; a transmission component is provided at the drive end of the motor 4. The transmission assembly includes a sleeve 6, which is rotatably connected to the outer wall of the motor 4. A fixing plate 7 is fixedly connected to the top of the sleeve 6. The sleeve 6 and the second sleeve 10 cooperate to provide axial connection and positioning for power transmission, ensuring transmission coaxiality and reducing vibration and wear. The fixing plate 7 serves as the lower load-bearing foundation of the shock-absorbing structure, providing an installation and limiting platform for shock-absorbing components such as the spring 13 and guide post 14, improving the consistency of shock absorption. A connecting plate 8 is fixedly connected to the top of the fixing plate 7, and a fixing plate 9 is fixedly connected to the top of the connecting plate 8. The second sleeve 10 is fixedly connected to the top of the fixing plate 9. Inside plate 18, a guide post 14 is fixedly connected. A gasket 11 is fixedly connected to the outer wall of the guide post 14. A second gasket 12 is fixedly connected to the outer wall of the guide post 14. Gaskets 11 and 12 are placed between the spring 13 and adjacent components to buffer and level, reduce friction loss, and improve shock absorption stability. A spring 13 is provided on the outer wall of the guide post 14. One end of the spring 13 is fixedly connected to one end of the gasket 11, and the other end of the spring 13 is fixedly connected to one end of the second gasket 12. The spring 13 absorbs the vibration energy during equipment operation through elastic expansion and contraction, effectively attenuating the vibration amplitude, protecting the core components, and reducing noise. Reference Figure 1 and Figure 3 The outer casing 1 has a fixed column 2 fixedly connected to its top, and the base 3 has a pump body 5 fixedly mounted on its top. A flange inner interface 22 is fixedly connected to the outer wall of the pump body 5. The flange inner interface 22 optimizes the internal sealing of the flange and pipeline, reduces the risk of water leakage, and improves the sealing reliability of the water supply path. A bellows 18 is fixedly connected to the outer wall of the flange inner interface 22. The bellows 18 utilizes its corrugated elastic deformation to absorb the displacement and deflection of the pipeline caused by vibration and thermal expansion and contraction, alleviates stress concentration at the connection point, and prevents leakage and pipeline cracking. The top of the corrugated pipe 18 is fixedly connected to flange 19, the bottom of the corrugated pipe 18 is fixedly connected to flange 15, the outer wall of flange 15 is fixedly connected to connecting plate 26, the outer wall of flange 29 is fixedly connected to connecting plate 31, the inner thread of connecting plate 321 is connected to guide post 27, the outer thread of guide post 217 is connected to bolt 20, the bolt 20, in conjunction with the nut, achieves a tight connection of the flanges and connecting plates, providing a high-strength detachable connection, ensuring the component connection is firm and sealed, and facilitating installation and maintenance.

[0019] Working principle: When using the vibration-damping water pump for the water diversion project pumping station, the power is transmitted to the fixed plate 9 via the sleeve 10. When the system vibrates, the spring 13 absorbs the vibration energy through elastic extension and contraction. The guide column 14 and the matching gaskets 11 and 12 limit the deformation direction of the spring 13, preventing it from deflecting or getting stuck. At the same time, the fixed plate 7, the connecting plate 8 and the sleeve 6 work together to effectively buffer the vibration during the power transmission process, thereby achieving vibration damping protection for the connection parts and ensuring the stability of power transmission between components.

[0020] When using the vibration-damping water pump for the water diversion project pumping station, the installation height and pre-tightening state of flange 19 and flange 15 are adjusted by cooperating with guide column 2 17 and bolt 20, so that the bellows 18 can adapt to the connection scenario of the pipeline or pump body 5. When the pipeline vibrates due to the operation of the pump body 5, or when it is displaced due to thermal expansion and contraction, the bellows 18 absorbs the radial, axial displacement and angular deflection of the pipeline by relying on the elastic deformation of its own corrugations. At the same time, connecting plate 2 16 and connecting plate 3 21 provide stable support to prevent the device from shifting, thereby realizing vibration reduction, deformation compensation and sealing at the connection between the pipeline and the pump body 5, and ensuring the stable operation of the water conveyance system.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
