detailed description

Below in conjunction with accompanying drawing, the effective mode of the technical scheme that the utility model solves the above-mentioned technical problem to take is described further:

A bicycle type water pump comprises a bicycle frame, a mechanical transmission part, a speed change part and a pump body.

The bicycle frame includes a vehicle seat 11, a handlebar 12, a vehicle body 13, and a support 14. Vehicle seat 11 is the seat when people step on pedal 21, and handlebar 12 can be supported by people when stepping on pedal 21, to increase riding comfort and stability, and variable speed controller 31 will be installed at 12 places of handlebar in addition. The body 13 is used to support the weight of the human body and provide installation space for the mechanical transmission part and the speed change part. The bracket 14 is used to support the vehicle body and maintain overall stability.

The mechanical transmission part includes a pedal 21 , a crank 22 , a crankset 23 , a chain 24 , a flywheel 25 , a crankshaft 26 , a rear axle 27 and a turntable 41 . The pedals 21 are for people to step on, and are symmetrically distributed on both sides of the vehicle body 13 . The crank 22 is connected to the pedal 21 and the crankset 23 . Chainset 23 is made up of a plurality of chainrings of different sizes, which can be adjusted with variable speed controller 31 . The crank 22 and the chainring set 23 are consolidated into one body, and the torque is transmitted to the chain 24 through the chainring shaft 26 . The chain 24 connects the chainring set 23 and the flywheel set 25, and plays the role of power transmission. Flywheel group 25 is installed on the rear wheel shaft 27, can unidirectionally rotate, and moment is delivered to rear wheel shaft 27; Two rotating discs 41 are fixed on the both sides of rear wheel shaft 27.

The speed change part is made up of a speed change controller 31, a rear speed changer 33, and a front speed changer 32. The speed change controller 31 is installed on the handlebar 12 and is responsible for controlling the front speed changer 32 and the rear speed changer 33. Front derailleur 32 is installed near the chainring of bicycle frame, is responsible for changing the chainring in the chainring group 23 of work, and rear derailleur 33 is installed near the rear axle 27 of bicycle frame, is responsible for changing the flywheel in the flywheel group 25 of work.

The pump body is made up of connecting rod 42, orifice plate 43, leather cup 44, pressure well 45, check valve 46, water inlet pipe 47, and water outlet pipe 48. Two turntables 41 are fixed on both sides of the rear axle 27. The turntables 41 are hinged to the connecting rod 42. The bottom of the connecting rod 42 is hinged to the orifice 43. A leather cup 44 is installed on the orifice 43. The leather cup 44 and the inner wall of the pressure well 45 are closely fitted. The water outlet pipe 47 is connected to the top of the pressure water well 45 , and the check valve 46 and the water inlet pipe 47 are at the bottom of the water pressure well 45 . The connecting rod 42 is hinged on one side of the rotating disc 41 with an eccentricity. The two rotating discs 41 on both sides are center-symmetrically fixed on the rear wheel shaft 27 , and the connecting line of the two hinge points passes through the rear wheel shaft 27 . Orifice plate 43 is the rigid plate of permeable water, and leather cup 44 is installed above, and water can enter the top of leather cup 44 from the below of leather cup 44, can not reverse flow. The pressure well 45 is a cylinder, the upper part is connected with the water outlet pipe 48, and the lower part is connected with the water inlet pipe 47. The outlet pipes 48 of two 45 pressurized wells finally converge into an outlet main pipe. The check valve 46 is positioned at the bottom of the pressure well 45, and water can flow from the check valve 46 bottom to the check valve 46 top without reverse flow.

In actual use, the water inlet pipe 47 is connected to the water source to be lifted. The person sits on the vehicle seat 11, holds the handlebar 12 with both hands, and steps on the pedals 21 on both sides in a cycle. The pedals 21 will drive the crank 22 to rotate, and the crank 22 passes through the teeth Disc shaft 26 drives crankset 23 to rotate, crankset 23 drives chain 24 to move, and chain 24 drives flywheel 25 to rotate, because flywheel 25 can only drive rear axle 27 to rotate in one direction, so will drive rear axle 27 to rotate, rear The wheel shaft 27 drives the turntables 41 on both sides to rotate, and the circular motion of the turntable 41 drives the two connecting rods 42 to do reciprocating planar movement, and then drives the orifice plate 43 and the leather cup 44 in the two pressurized wells 45 on both sides to move up and down. Because the turntables 41 on both sides are installed symmetrically in the center, so when the orifice plate 43 on one side moves downward, the orifice plate 43 on the other side will move upward, and then the water will be extracted from the water inlet pipe 47 alternately, and the water from the pressurized well 45 will be extracted. Water continuously flows out from the water outlet pipe 48, and finally gathers in a water outlet main pipe and flows out.

The utility model is not limited to the above-mentioned embodiments. Without departing from the essential content of the utility model, any deformation, improvement and replacement conceivable by those skilled in the art all fall within the scope of the utility model.
