[0024] In this embodiment, Figure 1-4 A shock-absorbing base for a centrifugal pump is provided. The utility model comprises a cylinder 1 and a cylinder body 6. The upper end of the cylinder 1 and the lower end of the cylinder body 6 are both open. The upper end of the cylinder 1 extends to the interior of the cylinder body 6. A bracket 2 is provided at the bottom of the cylinder 1. A telescopic plate 3 is provided inside the cylinder 1. A shock-absorbing mechanism 4 is provided between the telescopic plate 3 and the cylinder 1. A limiting mechanism 5 is provided between the telescopic plate 3 and the cylinder 1. A connecting column 7 is provided between the top of the telescopic plate 3 and the inner top wall of the cylinder body 6. A cross plate 8 is provided on the top of the cylinder body 6. A plurality of mounting holes 9 are evenly provided on the top of the cross plate 8.
[0025] In this embodiment, the pump foot of the centrifugal pump is fixed on the transverse plate 8 by fasteners cooperating with the mounting holes 9 on the transverse plate 8. When the centrifugal pump generates vibration during operation, the vibration will be transmitted to the transverse plate 8, the cylinder 6, the connecting column 7 and the telescopic plate 3, and the centrifugal pump is subjected to shock absorption treatment by the shock absorbing mechanism 4 to keep the centrifugal pump in a normal working state and extend its service life. At the same time, the limiting mechanism 5 can limit the transverse plate 8, the cylinder 6, the connecting column 7 and the telescopic plate 3 to keep the transverse plate 8 and the centrifugal pump in a stable state without displacement.
[0026] Preferably, as another embodiment of the utility model, the bracket 2 includes a fixing hole 21, a circular plate 22 and a support column 23. The bottom of the cylinder 1 is provided with a support column 23, the bottom of the support column 23 is provided with a circular plate 22, and a plurality of fixing holes 21 are opened around the top of the circular plate 22.
[0027] In this embodiment, the fixing hole 21 on the circular plate 22 can be fixed at a desired position by fasteners, and the cylinder 1 can be supported by the cooperation of the circular plate 22 and the support column 23. At the same time, it is higher than the fixing hole 21 on the circular plate 22 to facilitate the disassembly and assembly of the fasteners.
[0028] Preferably, as another embodiment of the utility model, the shock absorbing mechanism 4 includes a damper 41, a limit rod 42 and a spring 43. The inner bottom wall of the cylinder 1 is provided with a limit rod 42 that penetrates to the top of the telescopic plate 3. The limit rod 42 is sleeved with a spring 43 whose two ends are connected to the inner bottom wall of the cylinder 1 and the top of the telescopic plate 3. A damper 41 is provided between the inner bottom wall of the cylinder 1 and the top of the telescopic plate 3. The limit mechanism 5 includes a slide groove 51 and a slider 52. The inner side wall of the cylinder 1 is provided with a plurality of slide grooves 51 extending vertically. The slide groove 51 is internally slidably connected to a slider 52 that extends to its outside and whose bottom is fixedly connected to the top of the telescopic plate 3.
[0029] In this embodiment, the slider 52 on the telescopic plate 3 slides in the slide groove 51 on the inner wall of the cylinder 1, so that the telescopic plate 3 cannot be deflected and can only move vertically, which plays a role of limiting. The cross plate 8, cylinder 6 and connecting column 7 connected to the telescopic plate 3 are also limited. When the centrifugal pump on the cross plate 8 generates vibration, it will be transmitted to the telescopic plate 3 and act on the spring 43, so that the spring 43 is stretched or compressed. At the same time, the telescopic plate 3 will slide vertically on the limiting rod 42, and the spring 43 mainly plays the role of buffering vibration energy. It can absorb and store energy and reduce impact force through its own expansion and contraction; the damper 41 is mainly used to consume vibration energy, convert mechanical energy into other forms of energy such as heat energy and dissipate it, thereby effectively suppressing the vibration during spring rebound, making the vibration decay and stabilize faster. The two complement each other and jointly achieve the shock absorption effect.
[0030] Preferably, as another embodiment of the utility model, the outer curved surface of the cylinder 1 is provided with a limiting ring 102 located below the cylinder body 6, a plurality of rubber gaskets 101 are evenly arranged on the top of the limiting ring 102, and a rubber layer 11 is applied on the top of the cross plate 8.
[0031] In this embodiment, the limit ring 102 can limit the cylinder 6 to prevent the telescopic plate 3 connected to the cylinder 6 from moving downward too far and exceeding the maximum compression distance of the spring 43, that is, the elastic limit, and can no longer return to its original state and perform its function. When the cylinder 6 moves downward, it hits the rubber gasket 101 on the limit ring 102. Since the rubber gasket 101 is made of rubber, and rubber has good elasticity and damping properties, it can effectively buffer and reduce shock. Among them, the rubber layer 11 is also made of rubber, and long arc grooves are evenly arranged on the top, thereby increasing the friction between the centrifugal pump foot, and the rubber layer 11 also has anti-slip, buffering and shock-absorbing properties, which can protect the centrifugal pump.
[0032] Preferably, as another embodiment of the utility model, the outer curved surface of the cylinder 6 is provided with a plurality of reinforcing blocks 13 which are distributed in a surrounding manner and the top is connected to the bottom of the horizontal plate 8, and the outer curved surface of the support column 23 is provided with a plurality of supporting legs 12 in a surrounding manner.
[0033] In this embodiment, the reinforcement block 13 enhances the strength of the connection between the cylinder 6 and the cross plate 8, enabling it to withstand greater external forces, pressures or loads to prevent deformation or damage, while the support legs 12 can support the equipment and provide stable support to ensure that the equipment can be firmly placed in a certain position to prevent tipping or shaking.
[0034] Working principle: The fixing hole 21 on the circular plate 22 can be fixed at the desired position by fasteners, and the cylinder 1 can be supported by the cooperation of the circular plate 22 and the support column 23, and the pump foot of the centrifugal pump is fixed on the horizontal plate 8 by the cooperation of the fasteners and the mounting hole 9 on the horizontal plate 8. When the centrifugal pump vibrates during operation, the vibration will be transmitted to the horizontal plate 8, the cylinder 6, the connecting column 7 and the telescopic plate 3. The slider 52 on the telescopic plate 3 slides in the slide groove 51 on the inner wall of the cylinder 1, so that the telescopic plate 3 cannot be deflected and can only move vertically, and the centrifugal pump on the horizontal plate 8 vibrates. When the vibration is transmitted to the telescopic plate 3, it will act on the spring 43, causing the spring 43 to stretch or compress. At the same time, the telescopic plate 3 will slide vertically on the limit rod 42, and the spring 43 mainly plays the role of buffering vibration energy. It can absorb and store energy and reduce the impact force through its own expansion and contraction; the damper 41 is mainly used to consume vibration energy, convert mechanical energy into other forms of energy such as heat energy and dissipate it, thereby effectively suppressing the vibration during spring rebound and making the vibration decay and stabilize faster. The two complement each other and jointly achieve the shock absorption effect to protect the centrifugal pump and extend its service life.
