Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and in particular to a vibration and noise reduction device for a water pump. Background Art

[0002] A water pump is a mechanical device that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is primarily used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. Water pumps are essential equipment in hydropower stations and are typically mounted on a base assembly in a designated location for operation. Existing water pump base assemblies have the following disadvantages:

[0003] 1) The vibration generated by the water pump during operation cannot be effectively eliminated. Long-term severe vibration will cause damage to the water pump;

[0004] 2) The noise generated by the water pump during vibration cannot be effectively eliminated, which makes people uncomfortable and will harm human health in the long run. Summary of the Invention

[0028] Figures 1 to 5 An embodiment of the vibration reduction and noise reduction device for a water pump of the present invention is shown. The vibration reduction and noise reduction device for a water pump of this embodiment includes a mounting base 1 and a support vibration reduction mechanism 2. A mounting platform 3 for mounting the water pump and an adjustment mechanism 4 for adjusting the horizontal position of the mounting platform 3 are slidably provided on the top of the mounting base 1. The support vibration reduction mechanism 2 includes an elastic vibration reduction component 5 and two support legs 6. The mounting base 1 is movably mounted on the two support legs 6, and the elastic vibration reduction component 5 is arranged between the mounting base 1 and the two support legs 6.

[0029] The water pump uses a vibration and noise reduction device, and the water pump is installed on the mounting platform 3. The adjustment mechanism 4 can adjust the horizontal position of the mounting platform 3 on the mounting base 1 so that the center of gravity of the water pump is at the center position of the mounting base 1, which is convenient for reducing vibration of the water pump. The water pump will vibrate during operation, causing the mounting base 1 to slide down along the support legs 6, compressing the elastic vibration reduction component 5 located between the mounting base 1 and the support legs 6. The elastic vibration reduction component 5 rebounds to cushion the mounting base 1, so as to achieve buffering and vibration reduction of the water pump, avoid damage to the water pump due to long-term vibration, and alleviate the noise generated by the vibration of the water pump to a certain extent, so as to avoid damage to human health.

[0030] In this embodiment, Figure 1 、 2 As shown in Figure 3, the elastic vibration damping assembly 5 includes two hinged seats 51 and an elastic member 52 disposed between the two hinged seats 51. A first connecting rod 53 is hinged between each of the two hinged seats 51 and the two support legs 6, and a second connecting rod 54 is hinged between each of the two hinged seats 51 and the mounting seat 1. Specifically, one hinged seat 51 is hinged to one support leg 6 by a first connecting rod 53 and to the mounting seat 1 by a second connecting rod 54. The other hinged seat 51 is hinged to the other support leg 6 by a first connecting rod 53 and to the mounting seat 1 by a second connecting rod 54. When the mounting seat 1 slides down the support leg 6 under the vibration of the water pump, the first connecting rod 53 and the second connecting rod 54 bring the two hinged seats 51 closer together, thereby compressing the elastic member 52 between the two hinged seats 51. The elastic member 52 rebounds, causing the two hinged seats 51 to move away from each other. The first connecting rod 53 and the second connecting rod 54 then act to cushion and reduce vibrations of the mounting seat 1. Preferably, the elastic member 52 is a spring.

[0031] More preferably, Figure 1 、 2 As shown in FIG3 , in this embodiment, a sliding sleeve 11 is provided at the bottom of the mounting base 1 corresponding to each support leg 6. The sliding sleeve 11 is movably mounted on the support leg 6, and the second connecting rod 54 is hinged between the hinge base 51 and the sliding sleeve 11. When the water pump vibrates, the mounting base 1 slides on the support leg 6 via the sliding sleeves 11.

[0032] In this embodiment, Figure 4 and Figure 5 As shown, an elastic force adjustment component 7 for adjusting the expansion and contraction of the elastic member 52 is further provided between the two hinged seats 51. The elastic force adjustment component 7 can adjust the expansion and contraction of the elastic member 52 according to the vibration amplitude of the water pump, thereby adjusting the rebound and buffering effect of the elastic member 52 to adapt to the vibration of different water pumps, with strong adaptability.

[0033] In this embodiment, Figure 4 and Figure 5As shown, the elastic force adjustment component 7 includes a double-headed screw 71, two guide rods 72 and two adjustment seats 73. The two guide rods 72 are movably arranged in the two hinged seats 51 respectively. The double-headed screw 71 is arranged in one guide rod 72 and is connected to the other guide rod 72. The two adjustment seats 73 are respectively connected to two sections of the double-headed screw 71 with opposite spiral directions. Elastic parts 52 are respectively provided between the two adjustment seats 73 and the two hinged seats 51. Specifically, the guide rod 72 is slidably connected to the articulated seat 51, and the double-headed screw 71 is rotatably connected to the guide rod 72. The elastic member 52 is sleeved on the double-headed screw 71. The vibration of the water pump causes the mounting seat 1 to slide down along the support leg 6. The two articulated seats 51 are slid close to each other on the guide rod 72 through the first connecting rod 53 and the second connecting rod 54, thereby compressing the elastic member 52. At the same time, by screwing the double-headed screw 71, the two adjustment seats 73 can be moved in the direction of approaching the articulated seat 51, further compressing the elastic member 52 to increase the resilience of the elastic member 52 and adapt to water pumps with large vibration amplitudes. If the double-headed screw 71 is screwed in the opposite direction, the two adjustment seats 73 will move in the direction away from the articulated seat 51 to reduce the resilience of the elastic member 52 and adapt to water pumps with small vibration amplitudes. It has a simple structure and good adaptability.

[0034] In this embodiment, Figure 4 and Figure 5 As shown, one end of the double-headed screw 71 extends outside the guide rod 72 and is provided with a rotating handle 74. The double-headed screw 71 can be rotated by screwing the rotating handle 74, which is convenient and labor-saving.

[0035] In this embodiment, Figure 1 and 2 As shown, the adjustment mechanism 4 includes a screw 41 and a rotating member 42 for rotating the screw 41. The screw 41 is disposed in the mounting platform 3 and is threadedly connected to the mounting platform 3. The rotating member 42 rotates the screw 41, driving the mounting platform 3 to slide on the mounting base 1, adjusting the water pump to the center position of the mounting base 1, thereby facilitating the buffering and vibration reduction of the water pump.

[0036] In this embodiment, Figure 1 and 2 As shown, two screw rods 41 are provided, located on either side of the mounting platform 3. A transmission gear 43 is fixedly connected to each screw rod 41, and a synchronization chain 44 is wound around the two transmission gears 43. Rotating one of the screw rods 41 drives the transmission gear 43 on that screw rod 41, which in turn drives the other transmission gear 43 and screw rod 41 via the synchronization chain 44, allowing both sides of the mounting platform 3 to slide simultaneously on the mounting base 1. This provides good synchronization and facilitates position adjustment of the mounting platform 3.

[0037] In this embodiment, Figure 1 and 2As shown, the mounting base 1 is provided with a chute 12, and the bottom of the mounting platform 3 is provided with a slider 31. The slider 31 slides in the chute 12, and a screw rod 41 passes through the slider 31 and is threadedly connected to the slider 31. The screw rod 41 rotates, driving the slider 31 to slide in the chute 12, thereby adjusting the horizontal position of the mounting platform 3 on the mounting base 1. Preferably, the chute 12 is a T-shaped chute, and the slider 31 is a T-shaped slider. This structure is simple and converts the rotational motion of the screw rod 41 into horizontal linear motion.

[0038] In this embodiment, multiple groups of support and vibration reduction mechanisms 2 are provided, and the multiple groups of support and vibration reduction mechanisms 2 are arranged at intervals along the length direction of the mounting base 1, thereby further increasing the buffering and vibration reduction of the water pump.

[0039] The vibration reduction process of the present invention is described below: First, the water pump is installed on the mounting platform 3, and the screw rod 41 is rotated to drive the slider 31 to slide in the slide groove 12, and the horizontal position of the mounting platform 3 on the mounting seat 1 is adjusted so that the center of gravity of the water pump is located at the center of the mounting seat 1; then, the water pump is turned on, and the water pump vibrates continuously during operation, causing the sliding sleeve 11 on the mounting seat 1 to slide down along each support leg 6, and through the first connecting rod 53 and the second connecting rod 54, the hinged seat 51 is moved on the guide rod 72 to a direction close to the adjustment seat 73. The elastic member 52 slides in the direction of compression, and the elastic member 52 rebounds, causing the hinged seat 51 to move away from the adjusting seat 73, and then the mounting seat 1 is buffered and vibration-reduced through the first connecting rod 53 and the second connecting rod 54, thereby achieving the purpose of buffering and vibration-reducing the water pump; at the same time, by screwing the double-headed screw 71, the adjusting seat 73 is moved closer to or away from the hinged seat 51 to adjust the expansion and contraction amount of the elastic member 52, thereby adjusting the rebound force of the elastic member 52 and the buffering and vibration-reducing effect on the mounting seat 1 to adapt to water pumps with different vibration amplitudes.

Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
