Description

Technical Field

[0001] The invention relates to a permanent magnet submersible sewage electric pump for mines, in particular to a flow guide mechanism of a permanent magnet submersible sewage electric pump for mines. Background Art

[0002] Submersible sewage pumps are used for underwater operations. Due to the complex underwater conditions, underwater foreign objects often block the submersible sewage pumps or the turbulent water flow collides with foreign objects to damage the submersible sewage pumps. Therefore, a deflector is installed to protect the submersible sewage pumps. The deflector is generally set outside the submersible sewage pumps to protect the submersible sewage pumps from underwater turbulence erosion, reduce the occurrence of foreign object blockage, and extend the maintenance cycle and service life of the submersible sewage pumps.

[0003] During the use of the existing submersible sewage electric pump guide cover, larger foreign objects in the sewage will flow into the guide cover, which may easily cause the sewage flow channel in the guide cover to be blocked by the foreign objects, causing the submersible sewage electric pump to idle when working. If the submersible sewage electric pump idles for a long time or idles frequently, the service life of the submersible sewage electric pump will be shortened or even burn out. If larger foreign objects in the sewage flow into the submersible sewage electric pump, the service life of the submersible sewage electric pump will be shortened, and it will affect the continuity of the submersible sewage electric pump during operation and the efficiency of sewage discharge.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the submersible sewage pump body is in the sewage and discharges the sewage, the guide cover body guides the sewage at the liquid inlet end of the submersible sewage pump body. When the foreign matter in the sewage flows to the bottom of the guide baffle plate under the suction of the water flow, the guide baffle plate can block the larger foreign matter in the sewage. The sewage will drive the guide impeller to rotate during the flow into the submersible sewage pump body, thereby driving the first rotating shaft, the hollow rotating shaft, the hollow scraper and the arc-shaped crushing knife on the cutting assembly to rotate. When the hollow scraper rotates, the foreign matter adsorbed on the lower surface of the guide baffle plate will be scraped off, avoiding the situation that the foreign matter is adsorbed on the lower surface of the guide baffle plate and the sewage is not smooth from entering the guide hole to the inside of the guide cover body. When the arc-shaped crushing knife rotates, the foreign matter in the guide hole and the foreign matter adsorbed on the lower surface of the guide baffle plate can be crushed, avoiding the situation that the larger foreign matter blocks the guide hole and the larger foreign matter covers the guide baffle plate to cause blockage.

[0018] 2. In the present invention, when the first bevel gear on the slitting assembly rotates, it will drive the second bevel gear on the reciprocating assembly to rotate, thereby driving the gear teeth on the rotating wheel to rotate. When the gear teeth on the rotating wheel rotate, they will mesh with the gears on the front end wall and the rear end wall inside the reciprocating frame for transmission. At this time, the reciprocating frame will make reciprocating linear motion, driving the L-shaped connecting rod to make reciprocating linear motion, thereby driving the rubber piston on the piston rod to make reciprocating piston motion in the piston cylinder, indirectly making the through hole on the hollow scraper in a reciprocating water absorption and drainage state, and then under the cooperation of the rotation of the hollow scraper and the reciprocating water absorption and drainage at the through hole, foreign matter adsorbed on the guide baffle plate can be effectively removed, avoiding the situation that foreign matter is adsorbed on the lower surface of the guide baffle plate, causing sewage to enter the guide cover body from the guide hole.

[0019] 3. When sewage flows into the body of the submersible sewage pump, it will drive the guide impeller to rotate, which not only guides the flow of sewage, but also drives the toggle plate to rotate, so that foreign matter flows to the outside of the guide mechanism body, further avoiding the situation where foreign matter is adsorbed on the lower surface of the guide blocking plate, causing sewage to enter the guide cover from the guide hole.

[0020] Therefore, the present invention avoids the situation where larger foreign objects in the sewage block the sewage flow channel on the guide mechanism body or the submersible sewage electric pump body, causing the submersible sewage electric pump body to run idle, thereby shortening the service life of the submersible sewage electric pump body or even burning out the machine, thereby improving the continuity and efficiency of the submersible sewage electric pump body in discharging sewage.

When the submersible sewage pump body 100 is in the sewage and discharges the sewage, the guide cover 240 guides the sewage at the liquid inlet end of the submersible sewage pump body 100. When foreign matter in the sewage flows to the bottom of the guide baffle 230 under the suction of the water flow, the guide baffle 230 can block foreign matter with a larger volume in the sewage.

When the first bevel gear 2514 on the cutting assembly 251 rotates, it will drive the second bevel gear on the reciprocating moving assembly 252 2527 rotates, thereby driving the gear 2524 on the rotating wheel 2525 to rotate. When the gear 2524 on the rotating wheel 2525 rotates, it will mesh with the gears on the front end wall and the rear end wall inside the reciprocating frame 2521 for transmission. At this time, the reciprocating frame 2521 will make a reciprocating linear motion, driving the L-shaped connecting rod 2523 to make a reciprocating linear motion, thereby driving the rubber piston 2534 on the piston rod 2531 to make a reciprocating piston motion in the piston cylinder 2535, indirectly making the through hole 2517 on the hollow scraper 2516 in a reciprocating water absorption and drainage state, and then reciprocating water absorption and drainage are performed at the rotation of the hollow scraper 2516 and the through hole 2517. With the cooperation of , foreign matter adsorbed on the guide baffle plate 230 can be effectively removed, avoiding the situation that foreign matter is adsorbed on the lower surface of the guide baffle plate 230, causing the sewage to be blocked from entering the guide cover body 240 from the guide hole 231. In the process of sewage flowing into the submersible sewage electric pump body 100, the guide impeller 223 will be driven to rotate, which not only guides the flow of sewage, but also drives the toggle plate 224 to rotate, so that the foreign matter flows to the outside of the guide mechanism body 200, further avoiding the situation that foreign matter is adsorbed on the lower surface of the guide baffle plate 230, causing the sewage to be blocked from entering the guide cover body 240 from the guide hole 231.Therefore, the present invention avoids the situation in which larger foreign objects in the sewage clog the sewage flow channel on the guide mechanism body 200 or the submersible sewage electric pump body 100, causing the submersible sewage electric pump body 100 to idle, thereby shortening the service life of the submersible sewage electric pump body 100 or even burning out the machine, thereby improving the continuity and efficiency of the submersible sewage electric pump body 100 in sewage discharge.
