Abstract

The utility model provides a turbine pump with natural flow. The utility model is dipped and installed in seas and rivers, and the hydraulic power of the natural flow is directly used to achieve the purpose of raising water through the turbine pump which is composed of a flow collector 10, a dynamic rotary impeller 1, the speed increasing box 2 of a gear and a centrifugal pump. The pump has the advantages of simple structure, small size, light weight, easy installation (an anchoring method or a fixing method can be used), wide adaptive range, less investment and low cost, when the turbine pump is installed, a dam and a machine pit are not needed to be built, places for installing the turbine pump can be selected randomly, the gears and the bearings used by the utility model adopt water to lubricate, and multiple turbine pumps can be connected in series or parallel for use.

Description

Turbine pump with natural flow

The utility model relates to a kind of waterpower equipment that pumps up water, and especially directly utilizes the natural flows turbine pump in Haihe River.

Known waterpower pumping-up project or appliance arrangement, machine hole all will be built a dam or build to installation, and engineering, investment are big, consumptive material, even can cause public hazards such as flooding farmland, village, directly utilize Haihe River natural flows turbine pump to pump up water so far and do not see that precedent is arranged.

Task of the present utility model just provides the natural flows turbine pump.As long as this pump soaks in the Haihe River that is contained in certain flow and flow velocity, flowing water is realized pumping up water by mechanism's effect in this pump.Its advantage is: machine hole need not be built a dam, be built to installation, scope can choose at random, and volume Xiao Yi installs (method of casting anchor or fixation all can), and used gear, bearing adopt water lubrication, the efficient height, and cost is low.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a cut-away view of the present utility model, wherein: 1. power rotary impeller, 2. gear speedup case, 3. initial velocity gearing shaft, 4. overdrive gear transmission shaft, 5. centrifugal pump impeller, 6. inspiration water pipe, 7. raise outlet pipe, 8. speedup box bearing support, 9. honeycomb duct, 10. slip ring, 11. draft tube, 12 drain gratings, 13. flowing water power;

As shown in Figure 1: its structure is by conical slip ring 10, honeycomb duct 9 and conical draft tube 11 constitute a waist drum profile, at the fixing gear speedup case 2 of the useful bearing support of honeycomb duct 9 inwalls 8, case 2 bodies (help afflux conical, supercharging, the speedup effect) end of slip ring 10, the initial velocity gearing shaft 3 of loading onto power rotary impeller 1 is arranged, the other end has the impeller 5 coaxial overdrive gear transmission shafts 4 that connect with centrifugal pump, initial velocity gearing shaft 3 in gear speedup case 2 is moving with overdrive gear transmission shaft 4 teeth, case 2 shells and centrifugal pump housing are affixed with bolt, centrifugal pump has inspiration water pipe 6, one sides to raise outlet pipe 7.

Working principle is referring to Fig. 1: the natural flows power 13 that certain flow, speed (1 meter per second～0.5 meter per second) are arranged, by drain grating 12, through conical slip ring 10, stream rushes at power rotary impeller 1, push away the initial velocity gearing shaft 3 and overdrive gear transmission shaft 4 of gear speedup case 2, and driving centrifugal pump impeller 5 rotations coaxial with axle 4, water just by inspiration water pipe 6 inspirations of centrifugal pump, is raised out from raising outlet pipe 7; As with many natural flows turbine pump by raising outlet pipe 7 serial connection or in parallel, can realize many extraordinarily effect and the functions of water-outlet quantity extraordinarily of water outlet lift, test through separate unit, the water outlet lift reaches more than 7 meters.
