Description

Foot-operated motor-driven dual-purpose vortex type negative pressure suction pump

The utility model relates to the improvement and the raising of irrigation and water conservancy equipment.

The whole nation has been popularized in kill-job (claiming foreign well again), basically replaced the primitive method of pulling out water with rope for drawing water from a well, yet the power that it consumed, the overwhelming majority are applied to wall friction and sky and return on the stroke, so slowly the amount of drawing water is little for rhythm, only adapt to the domestic water needs, and can not satisfy the process water needs, in addition this device all be fixed on certain a bit on, can not move, needing in addition all needs to build in addition on other ground, especially to river, half congealed, lake ... surface water draws then powerless.

The purpose of this utility model is to have ready conditions locally with motor-driven for farmland-use water provides a kind of, and foot-operated moving in unconditional local personnel selection, at any time movably, drought is then irritated, and waterlogs and then arranges vortex type negative pressure suction pump technological scheme.

The purpose of this utility model is achieved in that

Overall structure is by the body of work device, and drive transmission device and binding frames device three part tectonic associations form.Wherein the body of work device is by cylindric pump chamber, spiral wheel and transmission shaft constitute, wherein the spiral wheel is integrally-built core apparatus, be to constitute by some reverse tilt angle blades that are, its diameter equates with the pump chamber internal diameter, together install the central position at pump chamber, the pump chamber inner chamber divides A, B, three working zones of C, A is the water reserve, B is spiral wheel working area, C is a negative pressuren zone, drives the mouth of a river in its bottom, mouthful one section water service pipe of outer fixing, the end is provided with a butt plate, dock with embedding underground bailing pipe or with drawing the flexible nylon tube of surface water, the construction system water drawing device is provided with an automatic valve in the middle of butt plate.When water body in the tube chamber that promotes to draw water by atmospheric pressure when tube wall rises, valve can be opened under gas flow pressure automatically, when current stopped, valve can be closed under action of gravity automatically; Open a water outlet that exceeds the indoor water surface at the top in A district, current are discharged thus, and prevent that atmosphere from entering in the chamber, makes complete machine malfunctioning; The overall structure of pump chamber is that lateral means is on the frame front frame that is made of the rectangular frame seat.The needed power of spiral wheel rotation, available electrical energy or mechanical energy obtain when conditions being possessed, otherwise stepping the driving rocking arm with manpower obtains, its structure: drive rocking arm and can follow the bicycle middle shaft package unit, transmission device then follows bicycle chain, flywheel part, through twice increment: by big (gear) and little, again by little and big, by big and little, act at last on the transmission shaft again, make the speedup coefficient become square multiple to increase.For alleviating operator's fatigue, also at the uniform velocity turn round for the crop rotation of workpiece spiral, add a flying wheel at an end of speedup switch transition axle, utilize the inertial force of its on-stream generation and manpower to be combined into to make a concerted effort to achieve the goal.

Concrete structure of the present utility model is provided by accompanying drawing:

Accompanying drawing 1 is foot-operated motor-driven dual-purpose vortex type negative pressure suction pump overall structure plan view;

Accompanying drawing 2 is foot-operated motor-driven dual-purpose vortex type negative pressure suction pump pump chamber device front elevation;

Accompanying drawing 3 is foot-operated motor-driven dual-purpose vortex type negative pressure suction pump spiral wheel schematic representation.

Now be following embodiment in conjunction with the accompanying drawings:

Before start, must perform following work:

1, fills with water in pump chamber 12 is thrown out air in the pump chamber with it, because water is to have this not have that material to air, vice versa.So water is indispensable interactional a kind of medium.

2, the other end of bailing pipe 20 inserts in the water in the district that draws water in advance, and perform the filtration measure, and prevent that impurity from entering in the tube chamber, still can not work done as finding start back a period of time, this explanation water level has ventilative place with upper part link bad sealing, should check and remedy.

3, the water lift height can not reach and surpass 10m, because test the high water column pressure of 10m factually, equals the pressure of atmospheric action in the water surface just, so barometric pressure also just loses the ability of work done.If in the time of must promoting the above height of 10m, that only takes ladder relay method that water is smash step by step to put on.

The start back is under powered, spiral wheel 13 rotates, 24 in the blade of rake angle is pushed the A district being located in the pump chamber 12 WATER AS FLOW MEDIUM to by the C district, make C district gradually reducing along with WATER AS FLOW MEDIUM, its atmospheric pressure value is also along with progressively reducing, by equipressure, low pressure, zero-pressure is so that negative pressure, thereby bring out the water body that the pressure of atmospheric action on the water surface promotes to retain in the bailing pipe 20 by the light of nature and rise along tube wall, going to make up the people is the imbalance that causes, replace the WATER AS FLOW MEDIUM role up to merging with WATER AS FLOW MEDIUM, and as long as the spiral wheel rotates not to be stopped, this situation also can continue forever.The size of the amount of drawing water depends on spiral wheel running speed, and both are directly proportional.

After the utility model was implemented, because the spiral wheel is continuous operation, the coefficient of impact that consumes in friction was minimum, thereby it is low to have energy consumption, the amount of drawing water is big, can adapt to general agriculturally to draw underground water surface water water-saving irrigation (sprinkling irrigation, drip irrigation) needs, and can be applicable to drain flooded fields.Also because it is a packaged type, as long as dock with former embedding underground bailing pipe, can carry out work, so need only embedding in advance bailing pipe 20 in the farmland, where need where just can be transported to, and currently can use plastic tube fully, nylon tube replaces expensive steel pipe, I once played the useful kill-job of a glance with bamboo trunk, thereby invested very to lack and just can achieve the goal.
