The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides an embodiment: a double-suction axially split pump body with good noise reduction effect comprises a base 1 and a motor 2, wherein the motor 2 is fixedly installed at the upper end of the base 1, the input end of the motor 2 is electrically connected with a switch through a lead, the output end of the switch is electrically connected with an external power supply through a lead, the model of the motor 2 is Y90S-2, the output end of the motor 2 is fixedly provided with a rotating shaft 3, the rotating shaft 3 penetrates through the inner wall of a double-suction axially split pump main body 4, fixed blocks 5 are fixedly installed at the left side and the right side of the bottom end of the double-suction axially split pump main body 4, the fixed blocks 5 are in threaded connection with the base 1 through fixing bolts 6, a first supporting rod 7 is fixedly installed at the upper end of each fixed block 5, the inner wall of each first supporting rod 7 is provided with a sliding groove 8, the upper end of each sliding groove 8 is provided with, can be when dismantling open pump main part 4 and base 1 in the double suction, move away briquetting 11 from fixing bolt 6's upper end, the installation of open pump main part 4 in the double suction has been made things convenient for, can also avoid fixing bolt 6 in vibrations simultaneously, thereby lead to not hard up, make produce the gap between open pump main part 4 in the double suction and the base 1, thereby produce great noise, influence the environment of work, vibrations between the two still can lead to the problem of damage between open pump main part 4 in base 1 and the double suction simultaneously, the noise of device has been reduced, make the noise reduction effect of device better, the life of device has still been improved simultaneously.

The inner wall of the sliding chute 8 is inlaid with a pressing plate 9, one end of the pressing plate 9, which is embedded into the sliding chute 8, is semicircular, the sliding chute 8 is also semicircular correspondingly, the pressing plate 9 can drive the sliding chute 8 to rotate on the inner wall of the sliding chute 8 while the inner wall of the sliding chute 8 slides, so that looseness caused by vibration of the fixing bolt 6 is avoided, a gap is generated between the double-suction axially split pump main body 4 and the base 1, and larger noise is generated to influence the working environment, meanwhile, the problem of damage between the base 1 and the double-suction axially split pump main body 4 caused by vibration between the two is solved, the noise of the device is reduced, the noise reduction effect of the device is better, the service life of the device is prolonged, the pressing plate 9 is fixedly connected with the inner wall of the lower end of the sliding chute 8 through a first spring 10, and a pressing block 11 is fixedly installed at the lower end of, the lower end of the pressing block 11 is attached to the upper end of the fixing bolt 6.

The impeller 13 is fixedly installed on the outer wall of the part of the rotating shaft 3, which is positioned inside the double-suction split pump main body 4, the brush 14 is installed at one end of the impeller 13, which is close to the inner wall of the double-suction split pump main body 4, the right ends of the brush 14 are embedded into grooves on the left side and the right side of the impeller 13, and the brush 14 is circularly distributed, so that when the blades of the impeller 13 are blocked by garbage, the rotating speed of the impeller 13 is slow, the brush 14 can clean the garbage inside the impeller 13, and simultaneously when the impeller 13 drives water flow to rotate at a high speed, the support plate 15 can be pushed, so that the support plate 15 inclines to one side, thereby avoiding the problem that the brush 14 is damaged, improving the problem of cleaning the inside of the device, and simultaneously prolonging the service life of the device, the support plate 15 is fixedly installed at one end of the brush 14, which is close, the inner wall of spheroid 16 is inlayed in the inner wall of arc wall 17, and arc wall 17 is seted up on second bracing piece 18, and the other end fixed mounting of second bracing piece 18 opens pump body 4's inside wall in the double suction, and the front and back both sides of second bracing piece 18 are close to one side fixed connection of opening pump body 4 in the double suction through second spring 19 and backup pad 15.

The working principle is as follows: when opening pump main part 4 in will double suction and base 1 are fixed together, at first pass base 1 and base 1 threaded connection through fixing bolt 6, then rotate clamp plate 9, make clamp plate 9 rotate at the inner wall of fluting 12, when clamp plate 9 aligns with the upper end notch of clamp plate 9, because the effect of first spring 10, make first spring 10 take place elastic deformation, pulling clamp plate 9 lapse, thereby drive briquetting 11 lapse, when embedding the inner wall of fixing bolt 6 upper end to the lower extreme of briquetting 11, thereby fix fixing bolt 6, avoid fixing bolt 6 because vibrations, rotate, thereby make and produce the gap between base 1 and the double suction opening pump main part 4, lead to producing great noise.

When impeller 13's flabellum department is blockked up, because the jam of rubbish, impeller 13's slew velocity reduces, make rivers reduce the impact force of brush hair 14, thereby extrude second spring 19, make second spring 19 take place elastic deformation, make backup pad 15 rotate forward, thereby make brush hair 14 and impeller 13's flabellum contact, clear up the rubbish of impeller 13 flabellum department, after rubbish clears up, the impact force of rivers will increase, make backup pad 15 extrude second spring 19, make second spring 19 take place elastic deformation, thereby make backup pad 15 drive brush hair 14 backward sliding, do not contact with impeller 13, impeller 13 slew velocity has been avoided causing the damage of brush hair 14 too fast.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
