Description

Technical Field

[0001] This utility model relates to the field of pump station technology, and in particular to an integrated device for heat dissipation and noise reduction of pump station motors. Background Technology

[0002] Large pump station motors are core power equipment in water conservancy projects, municipal water supply and drainage and industrial systems. Their design focuses on high efficiency, high torque and long service life, and they are adapted to harsh environments such as humid and dusty environments. They are widely used in flood control and drainage, water diversion projects and sewage treatment, and are key equipment to ensure the reliable operation of infrastructure.

[0003] However, existing technologies have some problems: In the existing technical solutions for pump station motors, traditional motors rely on heat dissipation fins on the casing for heat dissipation, which is difficult to effectively dissipate the dense heat generated during high-power operation, and is prone to causing excessive temperature rise. In addition, motors generally adopt a rigid mounting structure, with a rigid connection between the casing and the metal base, resulting in no attenuation of mechanical vibration energy transmission, which can easily induce resonance and collision noise of components. At the same time, rigid contact exacerbates the diffusion of high-frequency noise. Therefore, we propose an integrated heat dissipation and noise reduction device for pump station motors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated device for heat dissipation and noise reduction of pump station motors. By incorporating a cooler and vibration damping components, the device improves the heat dissipation and noise reduction effects on the motors.

[0005] The purpose of this utility model is achieved as follows: A pump station motor heat dissipation and noise reduction integrated device includes a base with a square groove.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] like Figures 1 to 4 As shown in the figure, the present invention provides an integrated device for heat dissipation and noise reduction of a pump station motor, including a base 1, a square groove 2 on the base 1, an assembly plate 3 inside the square groove 2, and a vibration damping component connecting the assembly plate 3 and the square groove 2. The vibration damping component can reduce motor vibration and thus reduce noise. A motor is mounted on the assembly plate 3, and a square box 4 located outside the motor is fixedly installed on the assembly plate 3. A cooler 5 is fixedly installed on the left side of the square box 4, and an air inlet pipe 6 is fixedly installed on the left side of the cooler 5. An air outlet pipe 7 is fixedly connected to the right end of the cooler 5, and the other end of the air outlet pipe 7 extends into the square box 4 and is rotatably connected to a sleeve 8. A nozzle 9 is fixedly connected to the sleeve 8, and a nozzle hole 10 is opened on the nozzle 9. The sleeve 8 and the square box 4 are also connected by a drive component, which enables the sleeve 8 to drive the nozzle 9 to rotate.

[0021] The sleeve 8 is rotatably connected to the air outlet pipe 7, usually using bearings, so that the sleeve 8 can rotate on the outer surface of the air outlet pipe 7. By starting the air cooler 5, the air inlet pipe 6 can draw in the outside air, convert it into cold air, and then deliver it to the inside of the sleeve 8 through the air outlet pipe 7. It then enters the nozzle 9 and is sprayed out from the nozzle 10, thereby cooling the motor. The vibration of the motor can be reduced by the vibration damping component, thereby reducing vibration noise.

[0022] Furthermore, the vibration damping assembly includes damping rods 15, with at least six damping rods 15. The damping rods 15 are fixedly installed at the bottom of the inner wall of the square groove 2, and the mounting plate 3 is fixedly installed on the top of the damping rods 15. Springs 16 are movably sleeved on the outer surface of the damping rods 15, and the two ends of the springs 16 are respectively fixedly connected to the inner wall of the square groove 2 and the surface of the mounting plate 3.

[0023] Through the design of damping rod 15 and spring 16, when the motor vibrates during operation, it will cause the assembly plate 3 to vibrate. The damping rod 15 and spring 16 can absorb and reduce the vibration force of the assembly plate 3, thereby reducing vibration and vibration noise.

[0024] Furthermore, the drive assembly includes a drive motor 11, which is fixedly installed on the left end of the square box 4. The output shaft of the drive motor 11 is fixedly sleeved with a round shaft 12. The other end of the round shaft 12 extends into the interior of the square box 4 and is fixedly connected to a drive gear 13. A driven gear 14 is fixedly sleeved on the outer surface of the sleeve 8, and the driven gear 14 and the drive gear 13 are meshed together.

[0025] By starting the drive motor 11, the round shaft 12 can drive the drive gear 13 to rotate, which in turn drives the sleeve 8 and the nozzle 9 to rotate through the driven gear 14. This allows the position of the nozzle 10 to be adjusted so that the nozzle 10 blows cold air to different positions on the outer surface of the motor, thereby improving the cooling effect on the motor.

[0026] Furthermore, two elastic pads 17 are fixedly connected between the bottom of the inner wall of the square groove 2 and the bottom surface of the assembly plate 3, and the two elastic pads 17 are arranged symmetrically.

[0027] The design of the elastic pad 17 can further enhance the support and vibration reduction effect of the assembly plate 3, thereby reducing vibration noise.

[0028] Furthermore, sound insulation panels 18 are fixedly installed on both sides and the top of the inner wall of the box 4, and sound-absorbing cotton 19 is fixedly installed on the sound insulation panels 18.

[0029] The design of the sound insulation panel 18 and the sound-absorbing cotton 19 can reduce the outward transmission of motor noise, thereby further improving the noise reduction effect.

[0030] Furthermore, through holes are provided on both sides of the bottom of the base 1, and a rubber pad 20 is fixedly installed on the bottom of the base 1.

[0031] The rubber pad 20 suppresses vibration transmission, reduces low-frequency noise during motor operation, and improves the working environment.

[0032] Working principle and usage process of this utility model:

[0033] When the motor is running, the operator can start the air cooler 5, which draws in external air through the air inlet duct 6, converts it into a cool airflow, and delivers it to the inside of the sleeve 8 through the air outlet duct 7. The air then enters the nozzle 9 and is sprayed out from the nozzle 10, thereby cooling the motor. At the same time, the operator can start the drive motor 11. The operation of the drive motor 11 causes the shaft 12 to drive the drive gear 13 to rotate, which in turn drives the sleeve 8 and the nozzle 9 to rotate through the driven gear 14. This allows the position of the nozzle 10 to be adjusted so that the nozzle 10 blows cool airflow to different positions on the outer surface of the motor, thereby improving the cooling effect on the motor. When the motor vibrates, it will cause the assembly plate 3 to vibrate. The damping rod 15 and the spring 16 can absorb and reduce the vibration force of the assembly plate 3, thereby reducing vibration and vibration noise. The design of the sound insulation plate 18 and the sound-absorbing cotton 19 can reduce the outward transmission of motor noise, thereby further improving the noise reduction effect, improving the stability of equipment operation and environmental friendliness.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
