Problems solved by technology

Though this device does not need working power supply or battery under normal circumstances, due to environmental reasons, or thermal initiator 13 is set unreasonably, thermal initiator 13 just may not feel when so breaking out of fire, at this moment, will wait until automatic If the fire is started, the fire may already be large, and even if the device is activated by the electric initiator 10 to extinguish the fire by manual electric start, the fire may expand due to untimely detection, resulting in greater losses.
In addition, the above-mentioned fire alarm devices can only monitor the temperature, so the detection results are relatively simple, so the reliability of the alarm is low

Embodiment 1

[0037] Such as figure 2As shown, the point-type composite fire detector based on the mechanical temperature sensing element provided in this embodiment includes a housing 1, a mechanical temperature sensing sensor 2, a smoke sensor 3, an indicator light 4, an alarm 5, a control device 6 and Power supply; where the front face 7 of the housing 1 is formed with a plurality of smoke inlets 8; the mechanical temperature sensor 2 and the smoke sensor 3 are installed inside the housing 1; the indicator light 4 and the alarm 5 are installed in the housing On the front end surface 7 of the body 1; the control device 6 is electrically connected with the mechanical temperature sensor 2, the smoke sensor 3, the indicator light 4 and the alarm 5; For powering the entire fire detector.

[0038] Such as image 3 As shown, the control device 6 includes a microprocessor 10, a photoelectric conversion unit 11, a signal output unit 12 and an external control unit 13; wherein:

Embodiment 2

[0055] Such as Figure 4 , Figure 5 As shown, the difference between the point composite fire detector based on the mechanical temperature sensing element provided in this embodiment and the point composite fire detector based on the mechanical temperature sensing element provided in Embodiment 1 is that the gas sensor 15 is used instead of the smoke sensor sensor 3. The gas sensor 15 adopts catalytic combustion type, electrochemical or semiconductor type, and is used to detect the gas concentration produced when a fire occurs. Meanwhile, the photoelectric conversion unit 11 in the control device 6 becomes a concentration conversion unit 16 accordingly, and other structures are the same.

Embodiment 3

[0057] Such as Figure 6 , Figure 7 As shown, the difference between the point-type composite fire detector based on the mechanical temperature sensing element provided in this embodiment and the point-type composite fire detector based on the mechanical temperature sensing element provided in Embodiment 1 is that the flame sensor 17 is used instead of the smoke sensor sensor 3. The flame sensor 17 adopts an infrared flame type, an ultraviolet flame type or a dual-band image type, and is used to detect the flame intensity and energy generated when a fire occurs, and the photoelectric conversion unit 11 in the control device 6 correspondingly becomes a flame intensity and energy conversion unit 18 , and the other structures are the same.

Abstract

The invention relates to a point-type complex fire detector based on a mechanical type temperature sensing element and an alarm method thereof. The detector comprises a shell, a mechanical type temperature-sensing sensor, a smoke-sensing sensor, a gas sensor or a flame sensor, an indicating lamp, an alarm, a control device and a power supply. The point-type complex fire detector based on a mechanical type temperature sensing element starts the smoke-sensing sensor, the flame sensor, the gas sensor and an electronic type temperature sensor by utilizing the passive action of the mechanical type temperature sensing element, thereby saving power and greatly improving the alarm reliability of the temperature sensing or smoke sensing or flame or gas fire detector under the condition of single use; and the invention can accurately and reliably finish all functions of detection, alarm, control and extinguishment of a small fire automatic extinguishing system particularly without utilizing alarm control of a fire alarm control host machine in a place without a power supply or with difficult power supply connection. The alarm method is simple and convenient.

Description

technical field [0001] The invention relates to a point type composite fire detector and an alarm method thereof, in particular to a point type composite fire detector based on a mechanical temperature sensing element and an alarm method thereof. Background technique [0002] Most of the commonly used fire alarm systems are composed of fire detectors, manual alarm buttons and alarm control hosts. When the fire detector detects a fire, or someone finds a fire and presses the manual alarm button, these devices immediately transmit the detection or induction signal to the alarm control host, and the alarm control host immediately links the fire extinguishing device to extinguish the fire after receiving the signal . However, this kind of fire alarm system needs to monitor the status of the detection elements and linkage elements in the system from time to time, so it needs to be equipped with a reliable power supply and consumes electric energy. Therefore, the system cannot be...
