Embodiment
Be described further below in conjunction with drawings and Examples.
Building drainage pipe potential energy power generation system comprises at least one electricity generating device 10 as shown in Figure 1, and electricity generating device is made up of drainage pipe 4, casing A 3, impeller 1, Gear combination transmission device and generator 8.Shown in Fig. 2 and 3, casing A 3 adopts slightly larger in diameter in the cylindrical shape of drainage pipe 4, casing A 3 and drainage pipe 4 vertical phase embeddings, and impeller 1 places in the space of casing A 3 and drainage pipe 4 intersections, and impeller 1 slightly larger in diameter is in drainage pipe 4.
As depicted in figs. 1 and 2, Gear combination transmission device and generator are arranged among the casing B 5.
The Gear combination transmission device comprises a secondary gear group, on the impeller shaft 2 of impeller, first order gearwheel 6 is set, first order gear drives generator interlock 9 by 7 transmissions of second level small gear, utilization is carried out a certain proportion of expansion with the rotating speed of impeller, thereby drive generator 8 high speed rotating, realize the function of generating.Being linked and packed of gear and gear shaft, mode are adopted gluing method.
Power loss in the gear transmission process mainly contains the friction of gear engagement, and the friction between the axle system is stirred oil and windage loss and (divided damage influence when high speed rotating bigger, can consider when the slow-speed of revolution.For native system,, divide the influence of decreasing to ignore because its rotating speed is not very high), the energy that vibration and noise are consumed.Wherein.The meshing power loss is a major component wherein, is the key that influences efficient.When load value must be, modulus is obvious to the influence of efficient, in general, the gear pair decrease in efficiency that modulus is big is more serious, its reason is under the situation of high loading, it mainly is that the sliding friction merit is decreased that the gear engagement merit is decreased, and the number of teeth of the first order of this device and second level gear is set at 64 and 16, and the public damage of sliding friction is less.In addition, the gear that diameter is more little, the sliding friction merit is decreased also big, and velocity ratio is big more, and merit is decreased big more.Consider tank-volumes, the consideration on cost and the efficient, the size design of gear is diameter 12cm and 3cm, adopts the combination of 3 secondary gear groups, the transmission effect is best.Overall calculation comes, and the efficient of gear can reach 96%, belongs to than higher efficient, sees Table 1.
When sewage flowed into drainage pipe, water will have certain gravitational potential energy aloft, and the size of gravitational potential energy then depends on the height of floor, supposes with ground to be reference level.When sewage fell from eminence, a part directly fell in the middle of sewer, and this part when dropping to certain height, will have a bigger kinetic energy only with the viscous resistance of considering between its resistance of air and the water.Some sewage falls along tube wall, and for this part influence that will consider an on-way resistance, the kinetic energy that obtains also can be littler than previous more.According to different floors, the electricity generating device of native system is installed, in general, in low floor building, electricity generating device is installed in the bottom, and for tall building, is in the consideration of optimum efficiency, the form that then adopts multi-layer classification to handle.When current touch impeller, the kinetic energy that current have will impact impeller, and impeller is rotated, thereby cause the impeller shaft rotation.Consider the strength problem of impeller, impeller will adopt high-intensity material, thereby avoid long-time impact and break impeller.Transmission device will adopt gear transmission, and in general, the transmission efficiency of gear can reach 96%, almost noenergy loss.
For generator, because generator for electricity generation needs high rotational speed, transmission device will be used the mode of multistage transmission, improve rotating speed step by step by the large gear turn the small gear, reach the rotating speed requirement of the required generating of generator.
The generator of electricity generating device 10 can adopt the direct current formula, output voltage is 12V, because the sewerage blowdown flow exists uncertain, the electric current that generating produces is very unstable, electric energy can not directly store, thereby after generating a rectifying device is installed, after the current stabilization, the current parallel that each independent power generating device is produced becomes network, and unification stores and utilization in accumulators collection.
The drainage pipe generated energy relies on the amount of high-rise row sewage down, when the sewage emissions amount is big, the generating efficiency height, sewage flow rate hour, generating efficiency is low, owing to the displacement size of sewage have period, so generating environment of this device and wind-power electricity generation environment facies are seemingly.On the generator speed problem, wind-power electricity generation has run into the problem of slow-speed of revolution generating, draws through scientific research personnel's experiment, rely on present generator techniques, even under the slow-speed of revolution, also can produce considerable voltage, below rated speed, also higher generating efficiency can be arranged.Test records, and the generating efficiency of this low-speed generator is not less than 74%, and when 72.5% rated speed, generating efficiency can reach more than 83%.
Wind generating unit generally adopts permanent magnet alternator, drives generator by wind wheel and produces Ac, becomes direct current and be stored in the storage battery behind over commutation.The utility model is similar in appearance to wind generating unit, simple the and easy realization than wind-power electricity generation again.So the utility model also can be used for reference wind-power electricity generation, adopt permanent magnet alternator, utilize the fluid impact impeller, the impeller transmission drives generator for electricity generation.The utility model can be used for reference wind power generating set fully at speed control system, commutation system and accumulating system, can be convenient to more like this produce and promote.
