Fig. 2 is the Air conditioner cabinet embodiment electric connecting relation figure with emergency protection function described in the utility model.
Embodiment
Be easier to understand to make content of the present utility model, now adopt the mode of specific embodiment by reference to the accompanying drawings, clear, complete description is carried out to the technical solution of the utility model, it should be noted that, embodiment described herein is only section Example of the present utility model, but not whole implementation of the present utility model, described embodiment only has exemplary, instead of limits the exhaustive of technical scheme described in the utility model.Without departing from the concept of the premise utility; all those of ordinary skill in the art do not make creative work just other execution mode thinkable; and other is to the simple replacement of technical solutions of the utility model and various change, all belongs to protection range of the present utility model.
As Fig. 1 illustrates a kind of execution mode of the present utility model, comprise front rear cabinet door 1, cabinet 2, air-conditioning 3, electromagnetic lock armature 4, electromagnetic lock 5, door open button 6, supply unit 7, temperature relay 8, audible-visual annunciator 9, travel switch 10, enabling spring lever 11.Described front rear cabinet door is located at cabinet two ends respectively, is respectively equipped with electromagnetic lockset between cabinet and front rear cabinet door, travel switch and enabling spring lever; Cabinet sidewall is provided with cabinet air conditioner, supply unit, door open button, and cabinet inwall is provided with temperature relay, and described cabinet is also provided with audible-visual annunciator; Be electrically connected between described cabinet air conditioner, electromagnetic lockset, door open button, supply unit, temperature relay, audible-visual annunciator, travel switch; Described electromagnetic lockset comprises forward and backward cabinet door electromagnetic lockset, and described door open button comprises forward and backward cabinet door door open button, and described travel switch comprises forward and backward cabinet travel switch.Described front and back electromagnetic lockset comprises electromagnetic lock armature and electromagnetic lock respectively, and described magnetic padlock armature is arranged at cabinet door enabling end inwall, and described electromagnetic lock is arranged at the cabinet sidewall position corresponding with described magnetic padlock armature; Described front/rear door travel switch is arranged at cabinet sidewall and front rear cabinet door respectively and opens the door and hold intersection.Described front rear cabinet door is provided with two cover electromagnetic locksets separately.The optional 12V Switching Power Supply of described supply unit.Described cabinet, cabinet door adopt the included flame resistant heat insulation material of double-layer plate to make.
Fig. 2 discloses a kind of electric connecting relation realizing the technical program, and external power source connects cabinet air conditioner and supply unit respectively by air switch, and supply unit is electromagnetic lockset loop and alarm loop power supply; Described supply unit is connected to front rear cabinet door travel switch parallel with one another, and front rear cabinet door travel switch parallel with one another connects audible-visual annunciator respectively, and audible-visual annunciator connects supply unit and forms audible-visual annunciator loop; Described supply unit connects temperature relay, takes back supply unit after dividing two-way to connect front rear cabinet door door open button and front rear cabinet door electromagnetic lockset respectively afterwards, forms electromagnetic lockset loop.Specifically, the extraneous 220V AC power provided to Air conditioner cabinet is powered to air-conditioning and 12V Switching Power Supply respectively after air switch.Switching Power Supply provides 12V DC power supply respectively to electromagnetic lock loop and alarm loop.The power supply of supply electromagnetic lock first after temperature relay (normally closed node arrives after rated temperature and disconnects), then is divided into two-way and receives on electromagnetic lock through push-button switch (normally-closed contact, press after disconnection).The power supply of supply alarm branch road is connected to audible-visual annunciator after parallel join door 1 and door 2 travel switch (normally-closed contact closes and disconnects behind the door).
Cabinet designs, and cabinet wall, cabinet door adopt the included flame resistant heat insulation material of double-layer plate, and design of opening the door before and after adopting, side perforate embeds cabinet air conditioner.In technical scheme described in the utility model, when air-condition faults causes cabinet internal temperature to rise to protection value, control automatically to open front rear cabinet door, adopt Natural Heat Convection.Cabinet door is closed and is adopted electromagnetic lock adhesive: under normal circumstances; electromagnetic lock powers up; armature during closedown cabinet door on electromagnetic lock tight adhesive cabinet door; when air-condition faults cannot freeze; temperature rises to protection temperature; temperature relay disconnects electromagnetic lock power supply, and electromagnetic lock release cabinet door armature, between cabinet door and cabinet, cabinet door flicks by spring lever.Door in travel switch leaves sensor senses and opens to cabinet door, starts sound and light alarm, notifies that attendant overhauls air-conditioning.
During normal door, cabinet sidewall is provided with door open button, and door open button is normally closed button, and when pressing, the contact of button disconnects, and electromagnetic lock dead electricity, cabinet door flicks by elastic body.
The course of work of technical scheme described in the utility model describes:
Under normal operation, after powering up to rack, firmly close cabinet door, and when cabinet door is near cabinet, electromagnetic lock holds the armature above cabinet door, and the rubber weather strip at cabinet door edge is by the gap filling between cabinet door and cabinet, and isolating inner air and outer air circulates.When equipment normally works, when cabinet internal temperature rises to air conditioner refrigerating start-up temperature, compressor of air conditioner entry into service, cabinet internal temperature declines, and when temperature drops to set point, compressor quits work, by the time when next temperature rises to set point again, compressor starts work.
Work as air conditioner fault, cannot freeze, cabinet internal temperature is caused to raise rapidly, when temperature rises to temperature switch operating value (as 50 degree), temperature relay break contact, electromagnetic lock power failure, both sides cabinet door is after electromagnetic lock loses the suction-combining force, under the active force of bottom spring lever, open cabinet door, dispel the heat under natural convection air condition, thus cabinet internal unit still can normally be worked the short time.The travel switch being now arranged on cabinet body door edge edge loses the pressure of door, and switch closes, and connects acoustic-optic alarm, reminds staff to overhaul air-conditioning equipment in time.
When on-the-spot applied environment temperature 45 degree, set cabinet air conditioner 35 degree of startups, 30 degree of shutdown, 50 degree of automatic door openings.Test 24 hours, find that rack works well.Fault test: after closing air-conditioning, along with the lasting heat radiation of equipment, cabinet internal temperature progressively raises, after 1 hour, rack automatic door opening ventilates, and start audible-visual annunciator, the internal unit short time works on.
