Abstract

The utility model discloses a pedal water pumping device. The pedal water pumping device comprises two folding sac bags, a pipeline, a valve and other parts which are matched with each other. By adopting the feet treading mode, the self-weight of the human body is used to make the water of the folding sac bags generate the pressure, so the water can be pressed into the water pumping device of the high position. The utility model can be used for the irrigation of the small scale and other water using situations, and the utility model can be used to instead of shoulder-taking, hand-carrying, dragon bone water wagon, etc. Compared with the shoulder-taking and hand-carrying mode, the pedal water pumping device has low labor intensity. Compared with the dragon bone water wagon, the pedal water pumping device has light weight and low cost.

Description

Pedal water pumping device

The utility model is that the foot-operated mode of a usefulness alternately steps toward the water lift that two folding capsule bags come water is sent to from lower eminence to body weight.

Often need rise to eminence to water from lower in production and the life, the lifting of big water gaging all drives machinery by power artificial or nature and finishes, as: motor, the water pump that motor drags, the hydraulic ram that current drive etc., but under the little motorless again situation of water lift amount, the manpower water lift is also using, as imperial water bone waterwheel, bail with bucket, choose, carry etc., the dragon-bone water lift materials are many, heaviness, efficient is low, and the water lift height is limited, bail highly lower, choose, though water lift is the limit for height degree not, when transporting water, the people must transport body weight for humans itself back and forth, and efficient is low and labor intensity is very big.

The utility model utilize human body weight be added on the sealing water body to generations pressure make the principle of water level rising, design a water pocket that can change volume when alternately supporting body weight with both feet and passing to the pressurized of two sealings, be equipped with pipeline, valve etc. and form a water lift, the people is alternately lifted the function that pin raises body weight to be done be converted into the potential energy that water is raise, reach the purpose of water lift.

Below in conjunction with description of drawings working principle of the present utility model, concrete structure and working condition:

As shown in Figure 1, foot-operated water pumper is by two capsule bags (1), (2), water inlet halter (3), inlet valve (4), (5), (6), intake pipe (7), flowing water Valve (8), (9), outlet conduit (10), add composition pumping systems such as water switch (11), its working principle is as follows: open earlier before the work and add water switch (11) and add water, make intake pipe (7) be full of water, close and add water switch (11), step on capsule bag (1), pull-up capsule bag (2), capsule bag (2) volume changes from small to big, produce negative pressure, water is washed inlet valve (4) open, (6) enter capsule bag (2), capsule bag (2) pull-up is stepped on to peak, water pressurized in the capsule bag (2) is closed inlet valve (6), flowing water Valve (9) is opened, water enters in the outlet conduit (10), capsule bag (1) pull-up simultaneously with it, the negative pressure that forms in the capsule makes inlet valve (4), (5) washed open by water, water enters in the capsule bag (1), owing to have negative pressure so flowing water Valve (8) to be in closed condition in the capsule bag (1), water in the outlet pipe (10) can not be back in the capsule bag (1), capsule bag (1) pull-up is stepped on to peak, capsule bag (2) pull-up simultaneously, the water pressurized in the capsule bag (1), hydraulic pressure is closed inlet valve (5), washing flowing water Valve (8) open makes water enter outlet conduit (10), water enters the capsule bag (2) of pull-up, capsule bag (1) simultaneously, (2) replacing pull-up mutually, stepping on, hydraulic pressure is gone into outlet conduit (10) and rise to certain altitude to overflow, reach water is taken out the purpose that hoists from lower.

Figure 2 shows that the structural representation of foot-operated water pumper, capsule bag (1) described in Fig. 1, (2), inlet valve (5), (6), flowing water Valve (8), (9), intake pipe (7), outlet conduit (10) etc. all is installed on the base plate (12), and intake pipe (7) is made up of suction sleeve (13) and water inlet valve cap (14), outlet conduit (10) is by following water outlet valve cap (15), and upper water-out valve cap (16) and outlet pipe (17) are formed.

Fig. 3 is the integral shaft mapping of foot-operated water pumper, Fig. 1, parts described in Fig. 2 mark with same sequence number in Fig. 3, as shown in Figure 3: the base plate (12) that each parts is housed is installed on the underframe (27), underframe has four holes on (27), squeeze into through this four hole in the soil so that foot-operated water pumper is firm with timber (28), the people stands on the pedal (18) during work, bipod is alternately trampled, make two capsule bags (1) of the pedal of ining succession (18), (2) alternately one press one liter, partially other for making the capsule bag depress Shi Buxiang, have borehole jack on the pedal (18) on guide rod (20), for the people can be stood firm and work at two pedals (18), on base plate (12), there are two holes to insert vertical rod (31), colligation grab bar (32) is gone up in vertical rod (31), be used as handrail during work, the capsule bag is depressed by body weight by foot pedal (18), but carrying on the pin of its lifting on stepping down in pedal loosens, need to make two pedals (18) traction mutually through traction gear (29) sheave block (30), depress on one side and draw the another side lifting simultaneously, promptly one of two capsule bags liter of one pressure all caused by people's body weight.Rope length in the height of grab bar (32) and the traction gear (29) can both be regulated easily.

Fig. 4 is folding capsule bag constructions axonometric drawing, circular or the rectangular folding cover that capsule bag (1), (2) make of canvas, leather, rubber etc., with pressing plate (19) two of folding cover is locked on pedal (18) and the base plate (12), for flanging in making the capsule bag inner pressurized not allowing when the setting-out outwards turns over drum, every layer interior flanging leads in the foot-operated water pumper in jail used valve with many on line (21) on the diametric(al) both sides can use homemade horizontal line, Figure 5 shows that the axle survey schematic representation of flat one-way valve.Inlet valve (5), (6) and outlet valve (8), (9) structure is identical, constitute by valve body (22) and valve seat (24), valve seat (24) is that of being loaded on the base plate (12) justifies cup, valve body (22) is equipped with the wooden plectane of an annulus (24) for the outer ring, opening and closing the valve opening hour offset or washing away for exempting from valve body (22), gib block (25) is housed on the valve body (22) and ends race circle (26), the proportion of valve body (22) should only be slightly larger than water, make it in water, can sink and cover on valve seat (24), can be washed open by very little hydraulic pressure because of only being slightly larger than water again because of overweighting water.Its working state is used to the inlet valve (4) in the water halter (3) into, because of can not guarantee to be in roughly level.Therefore be difficult to guarantee that valve body (22) by slightly fitting with valve seat (24) than depositing in water, needs to award pressure with elasticity such as elastic cords and fits, perhaps use homemade ball valve.

The utility model can make the people only with the action that is equivalent to go upstairs, by the pressure of body weight to the water generates in the water pocket hydraulic pressure is hoisted, complete machine structure is simple, and materials are few, to not having specific (special) requirements with material, timber, plastics, sheet iron etc. all can use, volume is little, in light weight, mobile, install and use all very convenient, than other manpower water lift and method, as bail, carry water, the labour intensity such as dragon-bone water lift is low, the efficient height.
