Description
Technical field
The present invention relates to elevator safety and energy-saving field, relate in particular to a kind of elevator outage automatic floor approaching mechanism.
Background technology
When elevator device meets with powering-off state in operational process, band-type brake can make car be parked in current location the rotor locking of elevator, avoids its free landing, guarantees the safety of personnel in car and railway carriage or compartment.But the position of car is uncertain, probably, between two layers of floor, this can bring very large difficulty to the rescue in the elevator personnel, increases the injured probability of trapped personnel.Common way is to install emergency battery additional, under the elevator powering-off state, with battery, drives cage operation to the flat bed state, opens the railway carriage or compartment door, the passenger by railway carriage or compartment out, guarantee safety.
Elevator motor, when the power consumption state, is to obtain energy from three phase network, and can consumes unnecessary energy by dead resistance when generating state.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of elevator outage automatic floor approaching mechanism with power saving function is provided, this device not only guarantees the safety of personnel in car and railway carriage or compartment, can also reach energy-conservation purpose simultaneously.
The present invention is achieved through the following technical solutions:
A kind of elevator outage automatic floor approaching mechanism, comprise motor, the first bridge-type inverter, the second bridge-type inverter, counterweight detection module, automatic floor-levelling controller, DC/DC module;
Described motor, the first bridge-type inverter and the second bridge-type inverter are connected successively;
Described motor also is connected with counterweight detection module, automatic floor-levelling controller and DC/DC module successively;
Described DC/DC module also with the first bridge-type inverter and the second bridge-type inverter between connection lead be connected;
Described automatic floor-levelling controller also connects the first bridge-type inverter.
Described DC/DC module also is connected with super electrode capacitance module.
With respect to prior art, the present invention has following advantage and beneficial effect:
Super capacitor is a kind of power supply between traditional capacitor and battery, can when elevator normally moves, as electric capacity, play the effect of burning voltage, can when elevator cuts off the power supply, as battery, provide energy to complete the work of flat bed to motor again.When motor, in the power consumption state and the energy of super capacitor module when enough, the energy of super capacitor module is by the DC/DC module, and inverter, arrive motor; When motor, in generating state and super capacitor module while also having redundancy charging space, the energy of motor is by inverter, and the DC/DC module is charged to the super capacitor module.During the three phase network outage, the energy stored in the super capacitor module, the operation of Guarantee control system, allow elevator under the Action of Gravity Field of car and counterweight, runs to level position.Thereby both guaranteed the safety of personnel in car and railway carriage or compartment, also reached energy-conservation purpose simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is more specifically described in detail.
Embodiment
As shown in Figure 1.Elevator outage automatic floor approaching mechanism of the present invention, comprise motor 4, the first bridge-type inverter 3, the second bridge-type inverter 1, counterweight detection module 7, automatic floor-levelling controller 6, DC/DC module 2;
Described motor 4, the first bridge-type inverter 3 are connected successively with the second bridge-type inverter 1;
Described motor 4 also is connected with counterweight detection module 7, automatic floor-levelling controller 6 and DC/DC module 2 successively;
Described DC/DC module 2 also with the first bridge-type inverter 3 and the second bridge-type inverter 1 between connection lead 8 be connected;
Described automatic floor-levelling controller 6 also connects the first bridge-type inverter 3;
Described DC/DC module 2 also is connected with super electrode capacitance module 5.
Electrical motor 4 is three-phase alternating current motor, electrical motor 4 and the first bridge-type inverter 3(three-phase) be connected, when motor 4, during in motoring condition, the first bridge-type inverter 3, by after the vdc inversion, is controlled start and stop and the rotating speed of motor 4.During in generating state, control start and stop and the rotating speed of motors 4 when motor 4 by the first bridge-type inverter 3, but this time, energy was to pass to DC side from motor 4.
The second bridge-type inverter 1(three-phase) with three phase network, be connected, when motor 4, in the power consumption state and super capacitor module 5 energy when inadequate, the three phasevoltage energy arrives motors 4 through the second bridge-type inverter 1, the first bridge-type inverter 3; When motor 4, in generating state and super capacitor module 6 while being full of, the energy of generation feeds back on three phase network by the first bridge-type inverter 3, the second bridge-type inverter 1.
When line voltage is normal, super capacitor module 5 is discharged and recharged by DC/DC module 2, and now super capacitor module 5 plays the effect of filtering direct current spike, burning voltage as electric capacity.When grid cut-off, super capacitor module 5 can be used as the power supply of emergency battery Guarantee control system.During outage, the band-type brake of elevator is locked by rotor, and lift car may be positioned at the optional position of floor, now by the electric weight of super capacitor module 5 interior storages, can maintain the work of control system.Automatic floor-levelling controller 6 is by the information of car, counterweight detection module 7, the direction rotation that makes rotor reduce along car, counterweight detection module 7 potential energy, the first bridge-type inverter 3 is controlled the speed of motor 4, motor 4 or the state in outside generating, the therefore required additional electrical energy minimum of flat bed in this way.When car safety while running to contiguous floor, open the railway carriage or compartment door.
Super capacitor module 5 is comprised of a lot of super capacitor monomer connection in series-parallel, the building form of the capacity of single super capacitor, withstand voltage and a plurality of monomers, will be according to the filtering requirements of DC voltage, and super capacitor module 5 releases energy and can not be less than under powering-off state needed ceiling capacity when elevator runs to the flat bed state and decide.
Just can realize preferably the present invention as mentioned above.
Above-described embodiment is better embodiment of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from the change of doing under Spirit Essence of the present invention and principle and should be equivalent substitute mode, is included in protection scope of the present invention.
