Background technology
Along with increasingly sharpening and the fast development of low-carbon economy of energy crisis, energy utilization rate more and more is subject to people's attention.When the pedestrian passes by the road surface, the road surface can deform and vibrate under pressure, these energy always slatterned in the past in vain, at the train station, the bus stop, large-scale shopping plaza, the place that flows of the people such as shopping mall are big, be used if the vibrational energy on road surface can be converted to electric energy, undoubtedly to energy-saving and cost-reducing significant.
The utility model content
The purpose of this utility model is to provide a kind of vibrational energy that the pedestrian can be trampled the road surface to be converted to the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of electric energy.
Problem described in the utility model realizes with following technical proposals:
A kind of stream of people tramples pressure generating set, it comprises tramples force transmission mechanism, piezoelectric ceramic power generation part, electric power generation part and energy storage section, the described force transmission mechanism of trampling is made up of pedal, spring support, drive link, bent axle, speed changer, described electric power generation partly is a generator, described piezoelectric ceramic power generation part is a piezoelectric ceramic, and described energy storage section is a storage battery; Described pedal is installed on underfloor, and one end and ground are hinged, and the other end drives bent axle through drive link; The power shaft of described speed changer is connected with bent axle, the output axle driven dynamo; The output of described generator connects storage battery through rectifier; Described spring supports and piezoelectric ceramic be installed on successively pedal below, the electrode of the output connection storage battery of piezoelectric ceramic.
The above-mentioned stream of people tramples pressure generating set, and described drive link is provided with two-stage, is in transmission connection by slide block between first order drive link and the second level drive link.
The above-mentioned stream of people tramples pressure generating set, and the output of described generator connects electrical appliance through transformer.

Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 1, spring supports; 2, first drive link; 3, second drive link; 4, bent axle; 5, piezoelectric ceramic; 6, storage battery; 7, rectifier; 8, transformer; 9, electrical appliance; 10, generator; 11, pinion; 12, gear wheel; 13, pedal; 14, slide block.
Embodiment
Piezoelectric ceramic 5 is to be under pressure to make voltage can appear in the time spent between both ends of the surface polycrystalline material.Piezoelectric ceramic has that macroscopical piezoelectricity is strong, dielectric constant is high, can be processed into arbitrary shape, but characteristics such as the mechanical quality factor is lower, electrical loss is big, poor stability.Adopt single piezoelectric ceramic to make the requirement that Blast Furnace Top Gas Recovery Turbine Unit (TRT) can not satisfy conventional electrical appliance.For this reason, the utility model will move and rotate switching mechanism and piezoelectric ceramic combination, constitute a kind of pressure generating set of practicality.
Referring to Fig. 1, in the utility model, the quantity of bent axle 4 and piezoelectric ceramic 5 can be provided with arbitrarily as the case may be, and Fig. 1 bent axle 4 and piezoelectric ceramic 5 respectively are provided with two.
Operation principle of the present utility model is as follows: with pedal 13, spring supports 1, piezoelectric ceramic 5 places below the gangway-floor, when trampling by human body, the floor produces the small amount of moving down δ (according to analysis of experiments, δ is about about 5mm, can not allow human body not feel well), the time pedal 13 rotate around the one end, first drive link 2 converts the rotation of pedal 13 to horizontal displacement, and promotion slide block 14 moves to right, making second drive link drive bent axle 4 rotates, the speed changer that is made of pinion 11 and gear wheel 12 is installed on the bent axle 4, gear wheel 12 and pinion 11 engagements, the rotation of bent axle 4 passes to pinion 11 by gear wheel 12, and the central shaft of pinion 11 links to each other with generator 10 by shaft coupling, pinion 11 drives generator 10 and rotates continuously, and system mechanics can be transformed into electric energy.Simultaneously, piezoelectric ceramic 5 generates electricity and under pressure to storage battery 6 charging.When electrical appliance 9 not electricity consumptions, generator 10 also can be to storage battery 6 chargings.
The utilization of this device output electric energy can be taked following manner: 1) can directly pass through current rectifying and wave filtering circuit, link to each other with storage battery, electrical power storage in storage battery, by charging and discharging of accumulator, is realized the utilization of electric energy.2) can pass through rectification circuit, utilize inverter then and boost, convert it into and be standard electric alternating current, electricity supply and use equipment uses, by circuit such as the detection control of electric voltage frequency, have the lasting stream of people by the time, with the electric energy power supply of directly being incorporated into the power networks.
