Abstract
The utility model relates to a water pump. The water pump comprises a pump body, a water inlet pipe, a water outlet pipe, a driving branch pipe, an impeller box, an impeller and a blade, wherein the water inlet pipe is connected with the pump body, the lower end of the water inlet pipe is provided with a filter screen, two ends of the driving branch pipe are respectively communicated with the water inlet pipe and the water outlet pipe through the side walls of the water inlet pipe and the water outlet pipe, the impeller box is fixedly arranged at one side of the driving branch pipe and is communicated with the driving branch pipe, the impeller is rotationally arranged in the impeller box, the impeller is connected with the blade through a transmission shaft, and the blade is located under the filter screen. According to the water pump disclosed by the utility model, the impeller is driven to rotate by a branch which is led out through the driving branch pipe, thus the blade can be driven to clean water plants at the lower end of the water inlet pipe, extra mechanism arrangement and an extra driving force are not needed, and the working efficiency of the water pump can be effectively increased.
Description
Technical field
The utility model relates to a kind of water pump.
Background technique
Water pump its intake pipe after the using process long period in inland river can cause the filter net jam that is arranged on intake pipe end due to foreign material such as pasture and water, because pasture and water are intricate, even if water pump has stronger suction also pasture and water can not be sucked to the pump housing, and for centrifugal pump, obstruction due to intake pipe, cause the negative pressure that the pump housing provides further to reduce, operating efficiency reduces greatly.
Summary of the invention
The utility model object is to address the above problem, and a kind of water pump with certain self-cleaning function is provided, and specifically by following technological scheme, is realized.
A kind of water pump, comprise the pump housing, the intake pipe being connected with the pump housing and outlet pipe, the lower end of described intake pipe is provided with filter screen, also comprise and drive arm, impeller box, impeller and blade, described driving arm two ends are communicated with intake pipe and outlet pipe by the sidewall of intake pipe and outlet pipe respectively, described impeller box is fixedly installed on and drives a side of arm and be communicated with driving arm, described impeller is arranged in impeller box rotationally, this impeller is connected with blade by transmission shaft, and described blade is positioned at described filter screen below.
Described water pump, it further designs and is, and described driving arm is provided with valve.
Described water pump, it further designs and is, and described valve is solenoid valve.
Thereby the utility model is cleared up the pasture and water of the lower end of intake pipe with cutting blade by driving arm to draw a tributary drives impeller rotation, without extra mechanism, arranges and driving force, can effectively improve the operating efficiency of water pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is further described.
This water pump, the intake pipe 2 that comprise the pump housing 1, is connected with the pump housing and outlet pipe 3, the lower end of intake pipe is provided with filter screen 4, also comprise and drive arm 5, impeller box 6, impeller 7 and blade 8, drive arm two ends by the sidewall of intake pipe and outlet pipe, to be communicated with intake pipe and outlet pipe respectively, impeller box is fixedly installed on and drives a side of arm and be communicated with driving arm, and impeller is arranged in impeller box rotationally, this impeller is connected with blade by transmission shaft, and blade is positioned at filter screen below.Valve is solenoid valve 9.
During normal operation, closed electromagnetic valve, now drives arm to be truncated, and its inside does not have current, thereby impeller and blade are not worked; When intake pipe stops up because of pasture and water, opens solenoid valve makes to drive arm to open, owing to driving the in succession intake pipe of bottom of arm one end,, there is negative pressure in intake pipe and in outlet pipe, have positive pressure in the in succession outlet pipe on top of one end, makes its inner current that form from top to bottom, current impeller is rotated, thereby blade starts to rotate, and gradually the pasture and water of intake pipe outside is cut off, and be positioned at the inner a small amount of residual pasture and water of intake pipe, can discharge smoothly with current.Also pressure transmitter can be set in rising pipe, pressure transmitter is connected with solenoid valve, when hydraulic pressure diminishes in rising pipe, start solenoid valve; When rising pipe hydraulic pressure is larger, solenoid valve cuts out automatically.
Thereby the utility model is cleared up the pasture and water of the lower end of intake pipe with cutting blade by driving arm to draw a tributary drives impeller rotation, without extra mechanism, arranges and driving force, can effectively improve the operating efficiency of water pump.
Claims (3)
1. a water pump, comprise the pump housing, the intake pipe being connected with the pump housing and outlet pipe, the lower end of described intake pipe is provided with filter screen, characterized by further comprising and drive arm, impeller box, impeller and blade, described driving arm two ends are communicated with intake pipe and outlet pipe by the sidewall of intake pipe and outlet pipe respectively, described impeller box is fixedly installed on and drives a side of arm and be communicated with driving arm, described impeller is arranged in impeller box rotationally, this impeller is connected with blade by transmission shaft, and described blade is positioned at described filter screen below.
