[0021] The following is a specific embodiment of the utility model and is combined with the drawings to further describe the technical scheme of the utility model, but the utility model is not limited to these embodiments.

[0022] As Figure 1 , Figure 2As shown, the high-performance shock-absorbing water pump includes a pump body 1, an installation base 2 arranged at the bottom of the pump body 1, a rubber pad 3 inlaid below the installation base 2 to reduce high-frequency vibration force, shock-absorbing devices 4 arranged at both ends of the pump body 1 to offset vibration force, the shock-absorbing devices 4 including a connecting lug 5 integrally formed with the pump body 1, a hydraulic base 6 with a hydraulic oil cavity, a piston column 7 movably connected to the hydraulic base 6, and an elastic member 8 for auxiliary buffering and shock absorption, the hydraulic oil cavity being filled with hydraulic oil, the piston column 7 penetrating into the hydraulic base 6 and movably and limitingly connected to the internal hydraulic oil cavity, the elastic member 8 being sleeved on the piston column 7 and abutting against the connecting lug 5 and the hydraulic base 6 at both ends, the shock-absorbing devices 4 being arranged in a relative structure and arranged at both sides of the pump body 1, and the hydraulic base 6 and the installation base 2 being fixed to the ground by bolt members.

[0023] The components of the shock-absorbing devices 4 work cooperatively to comprehensively suppress high-frequency, low-frequency and multi-directional vibration, and the efficiency of vibration transmission is reduced by more than 70%. By combining the variable stiffness spring with the hydraulic system, different loads and vibration frequencies are adapted, and the dynamic response capability is improved. The integrally formed connecting lug 5 and hydraulic base 6 enhance the structural strength, avoid fatigue fracture of the components caused by long-term vibration, and the anti-aging design of the silica gel damping pad 10 and the rubber pad 3 prolongs the service life and reduces the maintenance frequency.

[0024] The bottom of the rubber pad 3 has a plurality of auxiliary parts 9 for improving shock-absorbing performance, the auxiliary parts 9 being arranged in a horn-shaped structure and being arranged at the bottom of the rubber pad 3 in accordance with intervals, and the rubber pad 3 and the auxiliary parts 9 being integrally formed.

[0025] The elastic member 8 is a variable stiffness coil spring, the coil density of the side close to the hydraulic base 6 being greater than the side close to the connecting lug 5, forming a stepped buffering effect, the spring wire cross section being in a trapezoidal structure, and the trapezoidal bottom edge of the side with greater density being directed towards the installation direction of the hydraulic base 6. The bottom end of the hydraulic base 6 is provided with a silica gel damping pad 10 for auxiliary improvement of shock-absorbing efficiency.

[0026] The rubber pad 3 at the bottom of the pump body 1 increases the adsorption area with the ground through the horn-shaped auxiliary part 9, absorbs and disperses high-frequency vibration energy. The hydraulic oil in the hydraulic base 6 generates a damping effect through the reciprocating motion of the piston column 7, and converts low-frequency vibration into heat energy for dissipation. The coil density of the variable stiffness coil spring gradually increases from the connecting lug 5 to the hydraulic base 6, forming a stepped buffering effect to avoid rigid impact. The shock-absorbing devices 4 arranged symmetrically at both sides cooperatively offset multi-directional vibration through the flow of hydraulic oil, spring compression / rebound and the frictional resistance of the silica gel damping pad 10. The hydraulic base 6 and the installation base 2 are fixed by bolts to ensure overall stability, while allowing the shock-absorbing devices 4 to deform flexibly to absorb energy. The trapezoidal spring wire cross section of the elastic member 8 provides stable support when compressed to prevent lateral deviation. The silica gel damping pad 10 at the bottom end of the hydraulic base 6 further suppresses residual vibration transmission to the ground.
