Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1-Figure 3, a kind of hydroturbine water intake device, comprise intake pipe 1, outlet pipe 2, housing 3 and impeller 4, the peripheral circumference of described impeller 4 is evenly provided with the shower nozzle 5 equal with the blade quantity of impeller 4, described shower nozzle 5 afterbody is all communicated with circular water pipe 6, described circular water pipe 6 one end is fixedly connected with shower nozzle 5, circular water pipe 6 the other end is communicated with square water pipe 7, the cross section of described each square water pipe 7 is identical, the diameter of each circular water pipe 6 is all less than the length of side of the cross section of square water pipe 7, centered by impeller 4, with 12 o'clock direction for starting point, in the counterclockwise direction, the diameter of each circular water pipe 6 increases gradually.
Particularly, described square water pipe 7 has 9, and 7 point three, 9 square water pipes are stacked to be put, and the cross section of described intake pipe 1 is square, and the cross section that described 9 square water pipes 7 are formed mates with the cross section of intake pipe 1.
Particularly, described square water pipe 7 is provided with filter screen 8 with the joint of circular water pipe 6.
Particularly, be connected by horn mouth 9 between described circular water pipe 6 with square water pipe 7.
Horn mouth 9 is set between circular water pipe 6 and square water pipe 7, is mainly used for transitional function.Because the cross-section area of circular water pipe 6 is less than the cross-section area of square water pipe 7, and the cross section of circular water pipe covers by the cross section of square water pipe 7 completely, so in order to prevent joint hydraulic pressure excessive, and the connection of circular water pipe 6 and square water pipe 7 is loosened, carry out transition and buffering with horn mouth 9.
Filter screen 8 is set between circular water pipe 6 and square water pipe 7, mainly prevents solid particle polluter from entering into water turbine inside, affect the running of whole equipment.
Because square water pipe has 9, so corresponding, circular water pipe 6 has 9, and shower nozzle 5 has 9, and the blade of impeller 4 has 9.When outside water is introduced in intake pipe 1, 9 circular water pipes 6 are entered in the joint of circular water pipe 6 and square water pipe 7, because 12 o'clock centered by impeller 4, square shower nozzle 5 was nearest apart from horn mouth 9, so corresponding, the diameter being connected to the circular water pipe 6 of this shower nozzle 5 is also minimum, according to this, along counterclockwise, the shower nozzle 5 of relevant position increases gradually from the water flow distance of horn mouth 9, and the diameter of circular water pipe 6 also increases gradually, the hydraulic pressure of 9 shower nozzles 5 so just can be made equal, namely the power acted on water wheels 4 is equal, thus realize the overall stress balance of water wheels 4.
Compared with prior art, the free-standing water flowing out structure design of this hydroturbine water intake device by adopting caliber different, reduce influencing each other between each shower nozzle 5, also make the pressure uniform of each shower nozzle 5 pairs of impellers 4, ensure that the persistency of the stable of whole hydraulic turbine structure and work.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
