Abstract

The utility model relates to a bicycle water pump which is characterized in that the utility model comprises a volute pump body, a pump cover, a closed four-stage speed-increasing box, a shaft seal, an impeller and a pump shaft, wherein, the pump cover is connected with the speed-increasing box whose box cover is provided with a concave semicircular fixing device. The complete machine of the water pump is fixed on the rake-forward girder of a bicycle by the fixing device. The aim that unpowered force drives the water pump to operate is realized by the gearing-up which is progressively generated by the engagement of a cylindrical gear which is arranged on the middle shaft of the bicycle and the inner gear of the speed-increasing box which is connected with the water pump. The utility model has the advantages of labor saving and time saving, and causes the water pump to obtain the positive effects of high rotating speed, deep distance, high lift distance and big flow.

Description

Bicycle water pump

The utility model belongs to the pump technology field, be a kind of be the water pump of power with the bicycle.

At present, existing small pump on the market all is by motor driving, and deficiency is not have electricity, having a power failure, voltage all can not make the water pump work done when low, and this water pump must be furnished with motor, and cost is higher, adds power transmission and transformation, vertical rod, drag funds such as line, expensive too high, the user bears and feels difficulty deeply.

In recent years, the little water pumps such as foot-operated, hand, hand that occur on the market with chain transmission, though not electricity consumption, great majority exist the suction journeys low, and flow is little, and lift is not high, and labor intensity is bigger, and manpower work can not wait shortcoming lastingly.

The purpose of this utility model is to provide a kind of not electricity consumption, oil firing not, and energy-conservation repacking bicycle is the water pump of power, the bicycle after the repacking still can keep the instinct of the original traffic tool; And can just can make water pump obtain to be higher than the rotating speed of three times in motor by people's legpower more easily.Whereby, realize water pump dark suction, soar the good effect of big flow.

The purpose of this utility model is such realization: a kind of repacking is the vehicle water pump voluntarily, by the pump housing, pump cover, pump shaft, and seal ring, impeller and a level Four speedup box constitute.Its feature: water pump is fixed on the oblique crossbeam of bicycle front, by improve the rotating speed of water pump in its multi pack all-in-one-piece level Four speeder.On the bicycle middle shaft of the transformation of the way, install the big column gear, get for of the chain-driven of bicycle large toothed disk with this gear with minor sprocket on the speedup box transmission ＂ I ＂ axle, changing chain-driven is gear transmission, can overcome friction and jiggly shortcoming of chain transmission polygon effect.

Advantage of the present utility model is: the drought that is mainly used in farmland, vegetable garden, orchard, terraced fields is irritated, waterlogging is arranged, pesticide is murdered worm, with replace that existing sprayer and low-lift pump are used for pesticide and irrigation and drainage can not have, do not carry out work under the oil firing situation, the peasant need not be invested greatly just can guarantee to obtain good harvest yet in drought, waterlogging, plague of insects year.

The utility model also can be used for the water pump field of other use simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a scheme of installation, and Fig. 2 is transmission principle figure.

Shown in the figure: speedup box 1, belt pulley 2, fastening screw trip bolt 3, shape fixed base 4, oblique crossbeam 5, axis 6.

The purpose of this utility model is achieved in that speedup box of one of flow passage components of water pump pump cover multi pack, speedup box is realized the level Four speedup by four phase axle cogged transmissions, water pump spindle is bearing on speedup box and the pump cover with two rolling bearings, the logical armored pump lid of the other end, the center hole of the pump housing, stretch into dress seal ring and impeller on the spindle nose of pump housing inner chamber, form the overcurrent system of pump, constitute the final assembly of single stage single suction volute pump.

The small gear that is exposed at outside the case at speedup box ＂ I ＂ axle is meshed with reequiping the big garden post tooth of adorning on the bicycle middle shaft, realize by moving up and down fixing device along the oblique crossbeam of bicycle in the third gear meshing gap, after the gap of 0.25 modulus is adjusted, again fixing device is fixed.Will make pump working need prop up the cycling start ladder this moment, and the people rides over and steps on bicycle on the bike saddle, but just pump water.

When the pump water conservancy project is done to finish by bike, at this moment need four Luo Yuan nails on the fixing device are unclamped, last moving device makes it gear and breaks away from engagement, and at this moment fixing device has just recovered the instinct of bicycle as the traffic tool again.Needn't move the chaining bar, people ride over the bicycle contact field of loading onto pump, or visit and all do not have overslaugh.

Alleged repacking bicycle is meant: the external gear of bicycle middle shaft and transmission is special accessory at random, the axis of this axis on original bicycle roughly the same, difference is for increasing system one place with transmission gearwheel internal diameter phase interference fit and be shaped on the diameter of axle of two keys conduction in a side of axle, other size of axle with former bicycle middle shaft roughly the same remains in its part in addition.

The gearwheel of adorning on the axis, the reinforcement nylon 66 that the material selection light weight is wear-resisting is made, and replaces chain transmission with gear, is in order to increase velocity ratio, to improve revolution speed and alleviate people's legpower, increasing endurance.

Driving gear in the speedup box adopts little modulus, the narrow flank of tooth, and moderate velocity ratio engagement keeps its stable drive, noise free, light, flexible.

The main part pump housing of water pump is selected the water conservancy diversion of scroll casing type for use, the impeller of middle specific speed, and the blade of twisted shape has good dark suction, soars, the characteristic of big flow, efficient, energy-conservation, anti-cavitation.

Claims

1, a kind of voluntarily, be by the pump housing, pump cover, the axle envelope, impeller, pump shaft and a level Four speedup box constitute, it is characterized in that: the pump cover two ends are shaped on positioning spigot, one end connects speedup box, the other end multi pack pump housing, pump shaft is bearing on casing and the pump cover by two rolling bearings, the other end of pump shaft passes through pump cover, the center hole of the pump housing, stretch into the axle head dress axle envelope and the impeller of pump housing inner chamber, form pump overcurrent system, a diameter of axle that is shaped on two key conduction and same big column gear phase interference fit is arranged on the bicycle middle shaft of Transform Type design, be contained on the change gear spindle nose of cylindrical gears with speedup box transmission ＂ I ＂ axle on the Transform Type design bicycle middle shaft, 13 kinds of same moduluses can be installed, the pick-off gear of the different numbers of teeth is meshed, constitute 13 kinds of disposable speed of pump shaft, and form the level Four speedup of pump shaft simultaneously, make water pump spindle obtain to be higher than motor, diesel engine 3-5 high rotating speed doubly.
