[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides two technical solutions:

[0024] Figures 1-5The first embodiment is shown: a water inlet anti-clogging submersible axial flow pump, comprising an axial flow pump machine 1, the water inlet of the axial flow pump machine 1 is provided with a filter assembly 2, the outer surface of the axial flow pump machine 1 is provided with a silt removal assembly 3, a linkage assembly 4 is arranged between the filter assembly 2 and the silt removal assembly 3, and a collection assembly 5 is arranged on the silt removal assembly 3; the filter assembly 2 comprises a filter cylinder 21 in communication with the water inlet of the axial flow pump machine 1, a thrust ball bearing 22 is arranged at the top end of the filter cylinder 21, and the thrust ball bearing 22 is connected with the end surface of the water inlet of the axial flow pump machine 1; the silt removal assembly 3 comprises a silt removal pipe 31, a silt inlet 32 is arranged on the outer wall of the silt removal pipe 31 near the bottom, a silt scraping plate 36 is arranged on the outer wall of the silt removal pipe 31 near the bottom and connected with the silt inlet 32, and the silt scraping plate 36 is in contact with the outer wall of the filter cylinder 21; a motor 33 is arranged at the top end of the silt removal pipe 31, the output end of the motor 33 is movably penetrated through the top end of the silt removal pipe 31 and extends into the interior, a shaft 34 is arranged on the output end of the motor 33, a helical blade 35 is fixedly sleeved on the outer wall of the shaft 34, a silt outlet pipe 37 is fixedly communicated with the silt removal pipe 31 near the top, and a fixed block 38 is fixedly sleeved on the outer surface of the silt removal pipe 31 near the middle, and the fixed block 38 is fixedly connected with the outer surface of the axial flow pump machine 1.

[0025] Specifically, the motor 33 is started to drive the shaft 34 to rotate, and the helical blade 35 rotates accordingly. Since the silt scraping plate 36 is in contact with the outer wall of the filter cylinder 21, and the filter cylinder 21 rotates synchronously with the shaft 34 through the linkage assembly 4, when the helical blade 35 rotates, the silt scraping plate 36 can scrape off the possible silt on the outer wall of the filter cylinder 21. The scraped silt enters the silt removal pipe 31 through the silt inlet 32. With the rotation of the helical blade 35, the silt is pushed along the silt removal pipe 31 to the top by the helical blade 35, and finally discharged through the silt outlet pipe 37, thereby realizing the removal of the silt and avoiding the silt from gathering near the water inlet of the axial flow pump machine 1 to cause clogging, thereby improving the anti-clogging effect.

[0026] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the linkage assembly 4 comprises a protective shell 41, a plurality of fixed columns 42 are arranged on the top surface of the protective shell 41, and the top end of the fixed column 42 is fixedly connected with the bottom end of the silt removal pipe 31. Two synchronous wheels 43 are arranged in the protective shell 41, a synchronous belt 45 is arranged between the two synchronous wheels 43, and a connecting shaft 44 is arranged at the top end of each of the two synchronous wheels 43. The outer wall of the connecting shaft 44 is movably penetrated through the inner top surface of the protective shell 41 and extends upward. The top end of one of the connecting shafts 44 is fixedly connected with the bottom end of the filter cylinder 21, and the other connecting shaft 44 penetrates through the bottom end of the silt removal pipe 31 and is fixedly connected with the shaft 34.

[0027] Specifically, the protective shell 41 in the linkage assembly 4 plays a role in protecting the internal structure, avoiding interference of the synchronous wheels 43 and the synchronous belt 45 during operation by silt, and is fixedly connected with the silt discharge pipe 31 through the fixing column 42, so as to ensure the stability of the installation position of the protective shell 41. The two synchronous wheels 43 are connected through the synchronous belt 45. When the shaft rod 34 rotates, the connecting shaft 44 fixedly connected with the shaft rod 34 rotates, and the synchronous rotation and synchronous transmission of the two synchronous wheels 43 and the connecting shaft 44 are realized through the synchronous belt 45, so as to drive the filter cartridge 21 to rotate synchronously, and ensure the coordination between the filter cartridge 21 and the silt discharge pipe 31, thereby further improving the silt prevention effect and working efficiency of the submersible axial flow pump.

[0028] In the embodiment, the collecting assembly 5 includes a filter box 51, and the filter box 51 is arranged below the silt discharge pipe 37. A plurality of filter holes are arranged on the inner bottom of the filter box 51, and a connecting block 52 is arranged on the outer surface of the filter box 51 and is fixedly sleeved on the outer wall of the silt discharge pipe 31.

[0029] Specifically, when the silt in the silt discharging assembly 3 is discharged through the silt discharge pipe 37 under the pushing of the spiral blade 35, the silt enters the filter box 51. When the silt enters the filter box 51, part of the liquid contained in the silt can flow out through the filter holes, so that the liquid is returned to the external environment. Since the particles of the silt are large, the silt cannot pass through the filter holes, so the silt is trapped in the filter box 51, thereby realizing effective collection of the silt and avoiding reflow of the silt.

[0030] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0031] When the axial flow pump machine 1 starts to work, water first passes through the filter cartridge 21 of the filter assembly 2, and the filter cartridge 21 filters the silt in the water. At the same time, the motor 33 of the silt discharging assembly 3 starts to work, and the motor 33 drives the shaft rod 34 and the spiral blade 35 to rotate. When the shaft rod 34 rotates, the filter cartridge 21 is driven to rotate through the linkage assembly 4. Since the silt scraping plate 36 is in contact with the outer wall of the filter cartridge 21, the silt scraping plate 36 scrapes the silt on the surface of the filter cartridge 21 during the rotation of the filter cartridge 21, and the scraped silt enters the silt discharge pipe 31 through the silt inlet 32. With the rotation of the spiral blade 35, the scraped silt moves upward along the silt discharge pipe 31 under the pushing of the spiral blade 35, and is discharged through the silt outlet 37. The discharged silt enters the filter box 51 of the collecting assembly 5. The excess water in the silt is discharged through the filter holes on the inner bottom of the filter box 51, so that the liquid is returned to the external environment. The silt is trapped in the filter box 51, thereby completing the collection and filtration of the silt, effectively avoiding the secondary silt caused by the silt lingering near the water inlet of the axial flow pump machine 1, and improving the silt prevention effect.
