Floating water pump

Abstract

The invention discloses a floating water pump, and belongs to the technical field of water pump equipment. An inner filtering screen barrel and an outer filtering screen barrel which are nested with each other are connected to a bearing ring arranged at the top end of a through-flow pipe, the inner filtering screen barrel is rotatably connected with a bearing inner ring, dispersing impellers are arranged on the inner wall of the inner filtering screen barrel, so that passing water flow drives the inner filtering screen barrel to rotate, a strip brush fixedly connected with the inner filteringscreen barrel is driven to slide along the outer side surface of the outer filtering screen barrel, large sundries attached to the surface of the outer filtering screen barrel are cleaned, accumulation and blocking are prevented, a filter screen is arranged at the connecting position of a drainage opening in the device and the through-flow pipe, a driven impeller is arranged at a same horizontal position of the interior of the through-flow pipe and the drainage opening, the water flow flowing from top to bottom drives the driven impeller to rotate, the strip brush at the outer end sweeps the filter screen surface, and the scraped sundries can be discharged to the outer end with water flow branch flow when rotate to a sundry-discharging opening of the right end of the through-flow pipe withthe strip brush; and the situation that the drainage efficiency is affected by sundry blocking is prevented, and the cleanliness of water pumping can further be improved.

Description

technical field [0001] The invention belongs to the technical field of water pump equipment, and in particular relates to a floating water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The floating water pump floats on the water surface, and the water inlet is generally 25~50 cm lower than the water surface. The advantage is that it is not affected by the mud and sand on the bottom of the water. It is used in aquaculture. Through the process of spraying the aquaculture water, the aquaculture water is fully contacted with the air, increasing the aquaculture water. oxygen content. [0003] At...
