Description

Technical Field

[0001] This utility model relates to the technical field of power pump bases, specifically a multi-functional shock-absorbing base for power pumps. Background Technology

[0002] Power pumps are typically fixed with bolts and a rigid base. The base is connected to the power pump or the ground for shock absorption using rubber material. However, power pumps vibrate during use due to the combined effects of mechanical and fluid excitation. Existing shock-absorbing bases are not very effective at damping power pumps, which can easily lead to physical damage and performance degradation of the equipment, thus affecting the normal use of the power pump in the long run.

[0003] Therefore, this utility model provides a multi-functional shock-absorbing base for a power pump to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing shock-absorbing base for power pumps has poor shock absorption performance, which can easily affect the long-term use of the power pump.

[0005] This utility model provides the following technical solution: a multi-functional shock-absorbing base for a power pump, including a pump body and a shock-absorbing component. The shock-absorbing component is installed at the bottom of the pump body. The shock-absorbing component includes a shell, a top plate, a piston, and an elastic element. The shell has a U-shaped structure and the top plate is longitudinally slidably installed at the opening. One end of the piston is fixedly installed at the lower end of the top plate. The other end of the piston is fixedly connected to the bottom of the shell. An elastic element is installed on the outer surface of the piston.

[0006] As an optional embodiment of this utility model, a first airbag is fixedly installed on the top of the base plate.

[0007] As an optional embodiment of this utility model, the piston component includes a cylinder and a plug body, with an inlet and an outlet respectively opened on both sides of the cylinder, and a one-way valve installed on both the inlet and the outlet.

[0008] As an optional embodiment of this utility model, the elastic element includes an upper limit body, a shock-absorbing spring, and a lower limit body. The upper limit body is fixedly installed on the top of the plug body, and the lower limit body is fixedly installed on the bottom of the cylinder body above the inlet or outlet. The shock-absorbing spring is fixedly installed above the lower limit body.

[0009] As an optional embodiment of this utility model, the one-way valve includes a plug, the inlet and outlet are both isosceles trapezoidal structures, the plug is installed at the inlet and outlet, and the stop is fixedly installed at the inlet and outlet.

[0010] As an optional embodiment of this utility model, an air pipe is fixedly installed at the outlet, and an air hole is opened on the surface of the top plate, with the air pipe communicating with the air hole.

[0011] As an optional embodiment of this utility model, a piezoelectric ceramic is fixedly installed below the upper limit body, and an annular pressure body is fixedly installed above the shock-absorbing spring.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the synergy between the piston and the elastic element. First, the elastic element absorbs kinetic energy and stores energy to rapidly reduce the peak impact force. Then, the pressure difference generated by the piston generates continuous resistance to continuously consume energy, thus forming a buffer gradient that is first gentle and then stable, thereby making the shock absorption more stable and improving the shock absorption effect.

[0014] 2. In this utility model, the piston component, while working with the elastic component to reduce vibration, can also utilize the airflow generated by the piston component to cool the heat source of the power pump by blowing air, thereby ensuring the normal operation of the power pump; furthermore, while the piston component works with the elastic component to reduce vibration, it can also use the piston component to drive the piezoelectric ceramic to intermittently contact the annular pressure body to apply pressure for power generation, which is beneficial to saving energy and improving energy utilization.

[0024] Based on the existing problem of poor vibration damping performance of power pump shock absorber bases, which can easily affect the long-term use of power pumps, such as... Figures 1 to 3 As shown, this embodiment of the present disclosure provides a multi-functional shock-absorbing base for a power pump, including a pump body 1 and a shock-absorbing assembly. The shock-absorbing assembly is installed at the bottom of the pump body 1. The shock-absorbing assembly includes a housing 2, a top plate 3, a piston 4, and an elastic element 5. The housing 2 has a U-shaped structure and the top plate 3 is longitudinally slidably installed at the opening. One end of the piston 4 is fixedly installed at the lower end of the top plate 3, and the other end of the piston 4 is fixedly connected to the bottom of the housing 2. An elastic element 5 is installed on the outer surface of the piston 4.

[0025] The housing 2 has a longitudinal groove 21, and the top plate 3 is slidably installed in the groove 21 and can slide longitudinally along the groove 21.

[0026] During the use of the power pump, the power pump is fixed above the top plate 3 by existing fixing methods, such as bolts or welding. When the power pump vibrates after starting, the power pump drives the top plate 3 to slide longitudinally, and the top plate 3 drives one end of the piston 4 to move longitudinally. When one end of the piston 4 moves longitudinally, it works with the elastic element 5 to reduce the longitudinal kinetic energy of the top plate 3, thereby reducing the vibration of the power pump above the top plate 3.

[0027] like Figure 1 As shown, a first airbag 6 is fixedly installed above the base plate. When the power pump and the top plate 3 move longitudinally downward, the top plate 3 also presses down the piston 4 or the elastic element 5, thereby pressing down the first airbag 6. This allows the piston 4, the elastic element 5, and the first airbag 6 to work together to dampen the power pump, which helps to improve the damping effect.

[0028] like Figure 2 and 3 As shown, the piston component 4 includes a cylinder 41 and a piston 42. An inlet 43 and an outlet 44 are respectively opened on both sides of the cylinder 41, and both the inlet 43 and outlet 44 are equipped with a one-way valve 45. When the power pump and the top plate 3 move longitudinally, the piston 42 reciprocates longitudinally within the cylinder 41. During this reciprocating movement, the piston 42 draws in external air through the inlet 43 and discharges air through the outlet 44, thereby damping the top plate 3 and the power pump through the resistance of the air pressure difference.

[0029] During the damping process, the compression spring first absorbs kinetic energy and stores energy to quickly reduce the peak impact force. Then, the pressure difference generated by the movement of cylinder 41 and piston 42 generates continuous resistance to continuously consume energy, thereby covering the entire stroke of damping and forming a buffer gradient that is first gentle and then stable, which makes the damping more stable and improves the damping effect.

[0030] It should be noted that, in this embodiment, the speed of air intake and exhaust can also be controlled, thereby generating a pressure difference in the cylinder 41 and using the pressure difference to dampen the top plate 3 and the power pump.

[0031] like Figure 2 As shown, the elastic element 5 includes an upper limit body 51, a shock-absorbing spring 52, and a lower limit body 53. The upper limit body 51 is fixedly installed on the top of the plug body 42, and the lower limit body 53 is fixedly installed on the bottom of the cylinder body 41 and above the inlet 43 or outlet 44. The shock-absorbing spring 52 is fixedly installed above the lower limit body 53.

[0032] During the process of the power pump and top plate 3 driving the plug 42 to move in the cylinder 41, the plug 42 drives the upper limit body 51 to move longitudinally back and forth, so that the upper limit body 51 intermittently contacts and squeezes the shock-absorbing spring 52 during the longitudinal movement.

[0033] like Figure 3 As shown, the one-way valve 45 includes a plug 451 and a block 452. The inlet 43 and the outlet 44 are both isosceles trapezoidal structures. The plug 451 is installed at the inlet 43 and the outlet 44, and the block 452 is fixedly installed at the inlet 43 and the outlet 44.

[0034] When the plug 42 reciprocates within the cylinder 41, its upward movement creates negative pressure within the cylinder 41, causing the plug 451 at the inlet 43 to move away from the inlet 43 and draw in external air. Simultaneously, it causes the plug 451 at the outlet 44 to come into contact with the outlet 44 and seal it. When the plug 42 moves downward, it compresses the air within the cylinder and causes the plug 451 at the inlet 43 to come into contact with the inlet 43 and seal it. Simultaneously, it causes the plug 451 at the outlet 44 to move away from the outlet 44 and discharge air. As the plug 451 moves to close or moves away from the inlet 43 or outlet 44, the resistive element 452 limits its movement, ensuring stable movement.

[0035] It should be noted that the position of the resist 452 can control the size of the opening of the plug 451 at the inlet 43 or outlet 44, thereby controlling the speed of air intake or exhaust, and thus facilitating the control of the pressure difference for shock absorption. In this embodiment, the resist 452 should be close to the inlet 43 or outlet 44 to maintain a stable distance between the plug 451 and the opening or outlet 44.

[0036] like Figure 1 and 2 As shown, an air pipe 46 is fixedly installed at the outlet 44, and an air hole 47 is opened on the surface of the top plate 3. The air pipe 46 is connected to the air hole 47. When the plug 42 moves down in the cylinder 41 to discharge air, the air enters the air hole 47 along the air pipe 46 and is blown towards the motor at the power pump along the air hole 47. This achieves both vibration damping by the shock absorption component and heat dissipation for the power pump, thereby enabling multi-functional vibration damping.

[0037] It should be noted that the air vent 47 can also be opened at other locations where the power pump is severely overheated. In this embodiment, the common heat source of the power pump, namely the motor, is cooled by blowing air.

[0038] like Figure 2 As shown, a piezoelectric ceramic 54 is fixedly installed below the upper limit body 51, and an annular pressure body 55 is fixedly installed above the shock-absorbing spring 52.

[0039] During the reciprocating movement of the upper limit body 51 driven by the plug body 42, the piezoelectric ceramic 54 moves back and forth with the upper limit body 51 and intermittently contacts the annular pressure body 55 above the compression spring to apply pressure. Thus, when the plug body 42 reciprocates and uses the air pressure difference to form a buffer gradient with the elastic element 5, which is first gentle and then stable, the vibration force of the power pump can also be used to make the piezoelectric ceramic 54 intermittently contact the annular pressure of the shock-absorbing spring 52 to apply pressure for power generation, which is beneficial to saving energy and improving energy utilization.

[0040] During the use of the power pump and vibration damping components, after the power pump starts, it drives the top plate 3 to move longitudinally within the slide groove 21. As the top plate 3 moves longitudinally, it drives the plug 42 to reciprocate longitudinally within the cylinder 41. When the plug 42 reciprocates within the cylinder 41, its upward movement creates negative pressure within the cylinder 41, causing the plug 451 at the inlet 43 to move away from the inlet 43 and draw in external air. Simultaneously, it causes the plug 451 at the outlet 44 to come into contact with the outlet 44 and seal it. When the plug 42 moves downward, it compresses the air within the cylinder and causes the plug 451 at the inlet 43 to come into contact with the inlet 43 and seal it. Simultaneously, it causes the plug 451 at the outlet 44 to move away from the outlet 44 and discharge air. Thus, the resistance of the air pressure difference dampens the top plate 3 and the power pump. Furthermore, when the piston 42 moves downward in the cylinder 41 to discharge air, the air enters the air hole 47 along the air pipe 46 and is blown towards the motor at the power pump along the air hole 47, thereby achieving heat dissipation of the power pump while the shock absorption component performs shock absorption, thus enabling multi-functional shock absorption.

[0041] When the top plate 3 moves the plug 42, the plug 42 moves the upper limit body 51 longitudinally back and forth. This causes the upper limit body 51 to intermittently contact and squeeze the damping spring 52 during its longitudinal movement, absorbing kinetic energy and storing energy to quickly reduce the peak impact force. Then, the pressure difference generated by the movement of the cylinder 41 and the plug 42 generates continuous resistance to continuously consume energy. This allows the elastic element 5 and the piston element 4 to work together to form a buffer gradient that is first soft and then stable, thus making the damping more stable and improving the damping effect.

[0042] Furthermore, during the reciprocating movement of the upper limit body 51 driven by the plug body 42, the piezoelectric ceramic 54 reciprocates with the upper limit body 51 and intermittently contacts the annular pressure body 55 above the compression spring to apply pressure. Thus, when the plug body 42 reciprocates and uses the air pressure difference to form a buffer gradient with the elastic element 5, which is first gentle and then stable, the vibration force of the power pump can also be used to make the piezoelectric ceramic 54 intermittently contact the annular pressure of the shock-absorbing spring 52 to apply pressure for power generation, which is beneficial to saving energy and improving energy utilization.

[0043] At the same time, the top plate 3, while driving the piston body 42 to move and absorbing shock through the piston component 4 and the elastic component 5, squeezes the first airbag 6, further improving the shock absorption effect through the flexible force of the first airbag 6.
