Description

Technical Field

[0001] The utility model relates to the technical field of door opening devices, in particular to a smoke temperature sensing automatic door opening device for a campus dormitory building. Background Art

[0002] Schools are typical crowded areas, and campus safety is a heavy responsibility. For students who live in schools, dormitories are their most important living places, and the safety management of dormitory buildings is extremely important. For boarding primary and secondary schools, usually, in order to facilitate the management of students, the main door of the school dormitory building is generally locked after the students go to bed at night. Although the school has arranged dormitory management teachers, due to various reasons, when a fire occurs, the main door of the dormitory building cannot be opened in time, which makes dormitory safety worrying.

[0003] The existing campus dormitory main door locks are mostly old-fashioned padlocks that need to be opened manually by the dormitory supervisor with a key. In the event of fire, earthquake and other dangerous situations, it is very easy to delay opening the door, thus missing the opportunity to escape. Summary of the invention

[0004] The utility model aims to provide a campus dormitory building smoke temperature sensing automatic door opening device which has a simple structure, high sensitivity and convenient opening.

[0005] The utility model adopts the following technical scheme to achieve its invention purpose: a smoke temperature sensing automatic door opening device for a campus dormitory building, comprising a door lock, on which an inner door opening switch and an outer door opening switch are arranged, the door lock is connected to a smoke temperature sensor and an audible and visual alarm arranged in the dormitory building, and the door lock is also provided with a remote control switch and an emergency alarm switch.

[0006] Furthermore, the door lock described in the utility model is an electromagnetic door lock, which is powered by a rechargeable lithium battery and is not affected by temporary power outages.

[0007] Furthermore, the inner door switch and the outer door switch described in the utility model are a six-pin two-speed switch, a momentary switch, a reset switch, a button switch, an electronic switch or a trigger relay switch for daily entry and exit use.

[0008] Furthermore, the remote control switch described in the utility model is a wireless remote control switch or a remote WIFI Bluetooth relay switch.

[0009] Furthermore, the smoke temperature sensor described in the utility model is one of an ion type smoke temperature sensor, a photoelectric type smoke temperature sensor, and a gas-sensitive type smoke temperature sensor, which can sense smoke and temperature signals, and process the signals and convert them into control actions.

[0010] Due to the adoption of the above technical scheme, the utility model has achieved the purpose of the invention better. The utility model is connected to the door lock with a smoke temperature sensor and an audible and visual alarm. When a fire or earthquake occurs, the relevant signal can be sensed and the door lock switch can be controlled to open automatically. By setting the remote control switch, people outside the building can open the door remotely by remote control, WIFI, or Bluetooth when they find a fire or earthquake. By setting the emergency alarm switch, manual control can be performed to start the audible and visual alarm and open the door lock at the same time. The utility model can also be used for emergency drills. Through manual control operation, the audible and visual alarm is started and the door lock is opened at the same time to simulate the occurrence of dangerous situations for emergency drills. The utility model has a simple structure, high sensitivity, and is easy to use. When a fire or earthquake occurs, the door lock can be automatically opened in multiple ways and directions, which is convenient for the evacuation and escape of people in the building.

[0012] Figure 2 It is a circuit schematic diagram of the utility model.

[0013] In the figure: 1 and 1' are smoke and temperature sensors; 2 and 2' are sound and light alarms; 3 is a lithium battery; 4 is an electromagnetic door lock; 5 is a voltage regulator module; 6 is a voltage regulator module; 7 is a WIFI Bluetooth dual-mode relay switch; S1 is an inner door switch; S2 is an outer door switch; S3 is an emergency alarm switch. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Depend on Figure 1 , Figure 2It can be seen that a smoke temperature sensing automatic door opening device for a campus dormitory building includes an electromagnetic door lock 4, which is powered by a rechargeable lithium battery 3. The electromagnetic door lock 4 is provided with an inner door opening switch S1 and an outer door opening switch S2 for daily opening from the inside and the outside. The inner door switch S1 and the outer door switch S2 are six-pin two-speed switches. The electromagnetic door lock 4 is connected with a smoke temperature sensor 1 and an acoustic and light alarm 2 set in various places in the dormitory building. The smoke temperature sensor 1 is an ion smoke temperature sensor, including a smoke sensing unit that can receive smoke signals, a temperature sensing unit that receives temperature signals, and a single-chip microcomputer that receives smoke temperature and temperature signals and converts them into control operations. After the smoke temperature sensor senses smoke or temperature signals, it drives the acoustic and light alarm 2 to control the opening and closing of the electromagnetic door lock 4; the electromagnetic door lock 4 is also provided with a remotely controllable WIFI Bluetooth dual-mode relay switch 7 and an emergency alarm switch S3. The setting of the WIFI Bluetooth dual-mode relay switch 7 allows people outside the dormitory to open the door lock remotely, winning precious evacuation time in an emergency. The setting of the emergency alarm switch S3 facilitates nearby people to manually control and start the acoustic and light alarm to open the door lock at the same time. In order to correct the influence of the line voltage on the lithium battery, the present embodiment is also provided with a voltage stabilizing module 5 and a voltage stabilizing module 6 on the smoke temperature sensor 1 and the electromagnetic door lock 4, respectively.

[0016] During daily use of the utility model, the inner door switch S1 and the outer door switch S2 are arranged in a locked device, together with the remote control key and the mobile phone equipped with the APP, and are controlled by the teacher. When the teacher and students enter and exit the gate at ordinary times, the inner door switch S1, the outer door switch S2, or the wireless remote control WIFI Bluetooth switch can be used to control the opening and closing of the door lock, and the alarm will not be triggered to sound an alarm. The utility model is powered by a 12v or 24v rechargeable lithium battery on a daily basis, and the operation is not affected by temporary power outages. In the event of a fire, the utility model detects smoke or temperature signals through the smoke and temperature sensor 1 arranged in the dormitory building, transmits the signal and activates the sound and light alarm 2, and automatically opens the door lock 4 at the same time, that is, opens the dormitory building gate; when the personnel outside the dormitory building discover a dangerous situation such as a fire, they can turn on the WIFI Bluetooth dual-mode relay switch 7 through remote control, open the door lock 4, and open the dormitory building gate, and the personnel in the dormitory building can quickly evacuate from the gate to escape from the fire scene.
