Description
Technical field
The invention belongs to control devices, and in particular to dust-proof with the mutual switching device of radiating to a kind of emergency power supply cabinet.
Background technology
Centrally connected power supply with the development of society, people's living standard increasingly improves, public group more and more walks
In public arena, City complex, subway, gymnasium, hospital etc., public arena emergency service becomes the element that can not ignore,
Emergency power supply be building occur fire behavior or other in emergency circumstances, escape lighting or other fire-fightings, the state of emergency are badly in need of
Various power supply for electrical equipment power supply, however when emergency power supply is used to power, power-on time does not reach specification requirement far, should
Urgent telegram source is just stopped, and one of reason is that equipment internal temperature is excessively high, and power supply core component is caused to be stopped.
Emergency power plant is backup power product, only can just be powered in commercial power interruption, in alternating current normal condition
Under, i.e., under emergency power supply inoperation condition, temperature and room temperature are basically identical in equipment, and when commercial power interruption, emergency power supply starts
Work, the temperature in device is increased with the increase of working time at this time, emergency power supply radiator in the prior art
It punches using fan or on door-plate and radiates, it is impossible to according to the size of the transformation adjustment ventilation hole of temperature, if heat dissipation is not filled
Branch causes emergency power supply to be stopped, and causes the massive losses of equipment.
Invention content
A kind of emergency power supply cabinet provided by the invention is dust-proof with the mutual switching device that radiates, the electromagnet block used the power on
Surrounding can generate magnetic field, solve the dust-proof coordination problem between heat dissipation of emergency power supply cabinet.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of emergency power supply cabinet is dust-proof with the mutual switching device of radiating, including installation foundation component, screen net component, permanent magnetism
Iron block, electromagnet block, controller, current source；
Wherein, the installation foundation component, connect with emergency power supply rack enclosure, electromagnet is fixed in top cross bar
Mounting groove；
Wherein, the screen net component plays dustproof effect, and on the surface of the installation foundation component, top is set
There is permanent magnetic iron block mounting groove；
Wherein, the permanent magnetic iron block be mounted on the screen net component upper end mounting groove in, and the S poles of permanent magnetic iron block to
On；
Wherein, the electromagnet block is mounted in the mounting groove of the installation foundation component upper end, electromagnet block after energization
Lower end be N poles；
Wherein, the controller is mounted on one end of the electromagnet block, control current source work；
Wherein, the current source is mounted on the electromagnet block and on the right side of the controller, receives the control
The signal that device is sent makes the electromagnet block be powered.
Further, it according to Ampere's law, after the electromagnet block leads to direct current, is generated around the electromagnet block
Magnetic field, and the lower end of electromagnet block is N poles.
Further, when emergency power supply works, there are strong electromagnetic force between the permanent magnetic iron block and the electromagnet block,
The permanent magnetic iron block is moved upwardly together with the screen net component under the action of electromagnetic force.
Further, when city power recovery, emergency power supply is stopped, and the permanent magnetic iron block and the screen net component are in weight
The position before being powered is returned under power effect.
Beneficial effects of the present invention：Magnetic field can be generated around the electromagnet block that the present invention uses the power on, works as emergency power supply
During work, screen net component moves up under the action of electromagnetic force, plays heat dissipation effect, and when city power recovery, screen net component is in weight
Power effect under return to original state, rise dust-proof effect, realize it is dust-proof with heat dissipation between mutual conversion, and have it is simple in structure, into
The characteristics of this is low, usability is strong.
Description of the drawings
In order to facilitate the understanding of those skilled in the art, the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is that a kind of dust-proof dust-proof status architecture with the mutual switching device that radiates of emergency power supply cabinet of the present invention is illustrated
Figure；
Fig. 2 is a kind of dust-proof radiating state structural representation with the mutual switching device that radiates of emergency power supply cabinet of the present invention
Figure.
Specific embodiment
A kind of emergency power supply cabinet is dust-proof with the mutual switching device of radiating, as shown in Figure 1, including installation foundation component 1, yarn
Screen component 2, permanent magnetic iron block 3, electromagnet block 4, controller 5, current source 6；
Wherein, installation foundation component 1 is whole device immobilizing foundation, is connect with emergency power supply rack enclosure that top is horizontal
Electromagnet mounting groove is fixed on bar；
Wherein, dustproof effect is played in screen net component 2, and on the surface of installation foundation component 1, top is equipped with permanent magnetism
Iron block mounting groove；
Wherein, permanent magnetic iron block 3 is mounted in the mounting groove of 2 upper end of screen net component, and the S of permanent magnetic iron block is extremely placed upwards；
Wherein, electromagnet block 4 is mounted in the mounting groove of 1 upper end of installation foundation component, the lower end of electromagnet block after energization
For N poles；
Wherein, controller 5 is mounted on one end of electromagnet block 4, control current source work；
Wherein, current source 6 is mounted on electromagnet block 4 and on the right side of controller 5, and the signal of the reception hair of controller 5 makes
Electromagnet block 4 is powered.
When alternating current powers off, emergency power supply starts to provide power supply for equipment, and inside is inverse during emergency power supply works
Become device and transformer generates heat, the controller 5 of emergency power supply control at this time works, and the outflow control signal of controller 5 is to electricity
Stream source 6, current source 6 receives leads to direct current after signal for electromagnet block 4, according to Ampere's law, electromagnet block 4 after energization
Surrounding generates magnetic field, and the lower end of electromagnet block 4 is N poles.
The upper end of permanent magnetic iron block 3 is that the lower end of S poles and electromagnet block 4 is there are strong electromagnetic force, due to permanent magnetism between N poles
Iron block 3 is connected with screen net component 2, and permanent magnetic iron block 3 is moved upwardly together with screen net component 2 under the action of electromagnetic force, is led at this time
Air port area becomes larger, and result of ventilating heat dissipation becomes strong.
When city power recovery, emergency power supply is stopped, at this time 5 dead electricity of controller, it is impossible to send out control signal control electricity
Stream source 6 works on, and magnetic so as to electromagnet block 4 disappears, and permanent magnetic iron block 3 and screen net component 2 return to just under the effect of gravity
Beginning state, the device regain original dirt exclusion capabilities.
In conclusion a kind of emergency power supply cabinet is dust-proof with the mutual switching device of radiating, in alternating current and two kinds of differences of meeting an urgent need
Under state, in the case of emergency power supply cooling machine cabinet, the dust-proof of emergency power supply cabinet and heat dissipation intelligence switching are realized.
Above content is only the design example and explanation to the present invention, affiliated those skilled in the art
