Description

Technical Field

[0001] The invention relates to the technical field of fire safety, and in particular to a cold storage fire detection device. Background Art

[0002] Cold storage can usually be divided into fresh-keeping storage, freezer and refrigerated storage. The temperature range of freezer is -20℃~-35℃, and the temperature range of refrigerated storage is -10℃~-20℃. If common point smoke and reflected smoke fire alarm systems are used within the above temperature range, fires are very likely to occur due to electrical equipment, low temperature environment, insulation materials, packaging materials, refrigerants and other reasons in the above environment. Therefore, fire safety of cold storage is the top priority of cold storage safety.

[0003] Chinese patent application No. 2023105832520 discloses an electrical fire alarm for cold storage, the technical solution of which is only applicable to the temperature monitoring and leakage detection of the electric heating of the cold storage door and the electric heating of the evaporator defrost drain pipe, and cannot be applied to fire detection and disaster prevention in extremely cold storage environments.

[0004] Chinese patent application No. 2022107341393 discloses a smoke fire detection system. This technical solution conducts self-organizing networking in a specific area and monitors building fires without the need for network infrastructure. It is also not suitable for fire detection in cold storage.

[0005] Chinese patent application No. 2023106176745 discloses a wireless smoke fire detection alarm device for firefighting, which uses a physical mechanical structure for smoke detection. The detection accuracy is low, and it cannot effectively detect the fire and minimize the loss. It may cause a large delay and cause greater losses, and cannot be used in practice.

[0006] Due to the extremely low temperature of the cold storage itself, ordinary point-type smoke detectors and through-type smoke detectors (the lowest operating temperature can only reach -10°C) are not suitable for this special occasion. Therefore, it is necessary to develop a fire detection device suitable for the special environment of the cold storage. Utility Model Content

[0007] In order to improve the deficiencies of the prior art, the present invention proposes a cold storage fire detection device, and the technical solution is as follows:

[0008] A cold storage fire detection device comprises a detector, a control unit, a display unit and a fire extinguishing unit. The detector is integrated with a built-in filter, a temperature sensor and a smoke detection module. The control unit receives the collected data of the detector, analyzes and issues relevant instructions. The control unit is integrated with Bluetooth, network and RS485 communication interfaces, and is linked to an audible and visual alarm device and a fire extinguishing device. The display unit displays fault, warning and fire alarm indication signals according to the instructions of the control unit.

[0009] Furthermore, the detector further includes a sampling unit, a detection unit, a command unit and an alarm unit.

[0010] Furthermore, the sampling unit further includes a sampling tube, a sampling hole, an antifreeze clamp, an external filter, a purge device and a condensate separator.

[0011] The cold storage fire detection device of the present invention can overcome the shortcomings that ordinary point-type smoke sensors and reflected-type smoke sensors are not applicable in this special occasion. The cold storage fire detection device of the present invention has high detection accuracy, a wide applicable working temperature range, and can better detect and identify potential fire risks.

[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] Please refer to Figure 1 The schematic diagram of the composition of the cold storage fire detection device of the present invention comprises a detector 10, a control unit 20, a display unit 30 and a fire extinguishing unit 40. The detector is integrated with a built-in filter, a temperature sensor and a smoke detection module (not shown in the figure). The control unit 20 receives the collected data of the detector, analyzes and issues relevant instructions. The control unit 20 is integrated with Bluetooth, network and RS485 communication interfaces, and links the sound and light alarm device and the fire extinguishing device. The display unit 30 displays fault, warning, fire alarm and other indication signals according to the instructions of the control unit 20.

[0017] refer to Figure 2 Schematic diagram of the detector composition of the cold storage fire detection device, the detector 10 further includes a sampling unit 101, a detection unit 102, a command unit 103 and an alarm unit 104.

[0018] refer to Figure 3 Schematic diagram of the sampling unit composition of the detector, the sampling unit 101 further includes a sampling tube 1011, a sampling hole 1012, an antifreeze clamp 1013, an external filter 1014, a purge device 1015 and a condensate separator 1016.

[0019] The working principle of the cold storage fire detection device of the present invention is as follows: the sampling unit 101 in the detector 10 continuously collects air samples from the protected area, which are filtered by the filtering device and then transmitted to the detection unit 102 for analysis. The analysis results are synchronously transmitted to the control unit 20. When the smoke concentration in the detected air sample reaches the preset alarm threshold, the command unit 103 and the alarm unit 104 in the detector 10 transmit signals to the control unit 20, which further send signals to send out sound and light alarms through the display unit 30, and can link the fire extinguishing system according to the alarm level.

The cold storage fire detection device of the present invention has high detection accuracy, a wide applicable working temperature range, and can better detect and identify potential fire risks.
