As shown in fig. 3, a first limiting groove 9 and a second limiting groove 10 are formed in the top wall of the third groove 38; the first limiting groove 9 is close to the first connecting hole 33 relative to the second limiting groove 10, a plurality of first limiting grooves 9 and second limiting grooves 10 are arranged corresponding to wave crests of the elastic elements 7 on two sides of the sliding piece 310, and gaps between adjacent first limiting grooves 9 are smaller than gaps between adjacent second limiting grooves 10. When the fire pump works, adjacent wave crests on the elastic element 7 on the extruded side are gradually close to each other and are gradually embedded into the first limiting groove 9 on the top wall in the third groove 38, so that the elastic element 7 has a supporting point in the continuous compression process, the fatigue stress of the elastic element 7 can be effectively relieved, and after the elastic element 7 on the compressed side is filled in the first limiting groove 9, the contact stability between the upper connecting plate 31 and the lower connecting plate 32 can be effectively improved, and the stability reduction of the fire pump body 1 caused by dislocation is avoided; although the elastic element 7 on the tension side correspondingly enters the second limiting groove 10, the elastic element 7 on the tension side has a certain vibration allowance, so that the elastic element 7 on the tension side can avoid the vibration to react on the fire pump body 1 in the vibration absorption process, and the installation stability of the fire pump body 1 is further improved.
The specific working process is as follows:
when the fire pump works, the damping mechanism 3 is arranged between the fire pump body 1 and the mounting seat 6, so that the shock influence of the motor 2 on the fire pump body 1 is reduced, the connection stability between the fire pump body 1 and the mounting seat 6 is prevented from being reduced, and the use stability of the fire pump body 1 is improved; the damping mechanism 3 also plays a role of a gasket and is used for improving the connection tightness between the fire pump body 1 and the mounting seat 6; in addition, the reinforcing seat 4 is arranged at the bottom of the fire pump body 1, so that the connection strength between the fire pump body 1 and the mounting seat 6 is further improved, and the connection stability between the fire pump body 1 and the mounting seat 6 is further improved by utilizing the first counter bores 41 and the second counter bores 42 which are arranged on the reinforcing seat 4 along the circumferential direction, so that the anti-falling function is realized;
with the installation of the fire pump body 1 on the installation seat 6, the upper connecting plate 31 and the lower connecting plate 32 enter the second groove 35, and the second groove 35 plays a role in limiting and positioning the upper connecting plate 31 and the lower connecting plate 32 firstly, so that the fire pump body 1 can be accurately and quickly installed; then, through the corresponding relation of a counter bore 41 and a connecting hole 33 and blind hole 36, use the stay bolt to install for damper 3 realizes leaning on the fastening connection of inside and mount pad 6, further avoids damper 3 to deviate from or skew the mounted position from fire pump body 1 and mount pad 6, and the condition that the relative mount pad 6 of fire pump body 1 that leads to takes place the slope appears, thereby improves the stability of the long-term use of fire pump body 1.
