Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See Figures 1 to 2 This utility model provides a safety alarm system for a quick-freezing warehouse, characterized in that it includes:

[0024] A door sensor 1 is installed at the door of a quick-freezing warehouse and is used to sense the opening and closing status of the door.

[0025] The guide rail sensing device 2 is used to be installed at the joint of the guide rail and to sense the opening and closing state of the guide rail.

[0026] Control element 3, the door sensing device 1 is electrically connected to the control element 3, and the guide rail sensing device 2 is electrically connected to the control element 3;

[0027] Alarm module 4, which is electrically connected to the control element 3;

[0028] When the door sensor 1 detects that the door is open, the alarm module 4 issues an alarm signal; when the rail sensor 2 detects that the rail is closed, the alarm module 4 issues a safety signal.

[0029] This utility model provides a safety alarm system for a quick-freezing warehouse, including: a door sensor 1, a guide rail sensor 2, a control element 3, and an alarm module 4. During operation, when the quick-freezing warehouse door is opened, the door sensor 1 immediately triggers the alarm module 4 to issue an alarm signal. After the door is opened, the guide rail of the quick-freezing warehouse begins to close. The guide rail sensor 2 detects that the guide rail is in a closed state, and the alarm module 4 then issues a safety signal. Only after the alarm module 4 issues a safety signal can the operator proceed to the next step, improving safety and operational efficiency, and effectively preventing accidents.

[0030] In a further embodiment of this invention, the number of door sensing devices 1 is several, the number of door sensing devices 1 corresponds to the number of doors of the quick-freezing warehouse, the number of guide rail sensing devices 2 corresponds to the number of door sensing devices 1, and the number of alarm modules 4 corresponds to the number of door sensing devices 1.

[0031] In this embodiment, when there are multiple blast freezers or multiple doors within a blast freezer, each door is equipped with a corresponding door sensor 1, a corresponding guide rail sensor 2, and a corresponding alarm module 4, all operating independently to ensure accurate monitoring of the safety status of each door, all under unified management by the control element 3. This setup enables real-time monitoring of the status of multiple blast freezers or multiple doors and guide rails within a blast freezer, ensuring the safe operation of the blast freezers.

[0032] In a further embodiment of this invention, the door sensing device 1 is a waterproof and freeze-proof limit switch.

[0033] In this embodiment, the door sensing device 1 is a waterproof and freeze-proof limit switch, designed to work stably under extreme temperature conditions, ensuring good sensing performance in the low-temperature environment of the quick-freezing warehouse. The limit switch has high durability and reliability, and relatively low cost, which can effectively reduce maintenance costs.

[0034] In a further embodiment of this invention, the door sensing device 1 is used to be installed on the side of the door frame of the quick-freezing warehouse.

[0035] In this embodiment, the door sensor 1 is installed on the side of the door frame of the quick-freezing warehouse. During the opening and closing of the door, this location is less affected by the alternating hot and cold temperatures, thereby reducing condensation and extending the service life of the sensor. At the same time, this location facilitates installation and maintenance, ensuring stable system operation and long-term reliability.

[0036] In a further embodiment of this invention, the rail sensing device 2 is a low-temperature resistant proximity switch, and the rail sensing device 2 is used to be embedded in the joint end of the rail.

[0037] In this embodiment, the rail sensing device 2 is a low-temperature resistant proximity switch. This proximity switch can sense whether the rail is closed without direct contact, reducing mechanical wear and preventing false alarms caused by contact. Furthermore, the low-temperature resistance of the proximity switch ensures normal operation of the equipment at extremely low temperatures. The rail sensing device 2 is embedded inside the joint end of the rail; this design not only improves sensing accuracy but also reduces its surface area exposed to the low-temperature environment, thereby further enhancing the stability and reliability of the equipment.

[0038] In a further embodiment of this invention, a shock-absorbing structure 201 is provided on the outer side of the guide rail sensing device 2.

[0039] In this embodiment, a shock-absorbing structure 201 is provided on the outer side of the guide rail sensing device 2. The shock-absorbing structure 201 is a shock-absorbing pad made of soft material, which can effectively absorb the vibration generated during the connection of the guide rail, thereby extending the life of the entire guide rail sensing device 2. At the same time, the design of the shock-absorbing structure 201 also ensures the accuracy of the sensing device, avoids false alarms or missed alarms caused by vibration, and improves the stability and efficiency of the system.

[0040] In a further embodiment of this invention, the guide rail sensing device 2 is a waterproof and freeze-proof limit switch.

[0041] In this embodiment, the guide rail sensing device 2 can also be a waterproof and freeze-proof limit switch. Compared with proximity switches, it is more convenient to install and maintain, and has a lower cost, making the operation of the equipment more economical and efficient.

[0042] In a further embodiment of this invention, the alarm module 4 is an audible and visual alarm, the alarm signal is a red light flashing and a voice prompt, and the safety signal is a constantly lit green light.

[0043] In this embodiment, the alarm module 4 is an audible and visual alarm. During operation, when the freezer door is opened, the door sensor 1 immediately triggers the alarm module 4. The audible and visual alarm emits a red flashing light and a voice prompt to the operator to wait for the guide rails to close before commencing work. After the door opens, the freezer guide rails begin to close. The guide rail sensor 2 detects that the guide rails are in a closed state, and the audible and visual alarm switches to a solid green light and disables the voice prompt, thereby ensuring the correctness of the operation process and improving work efficiency. In addition, the alarm module 4 can also promptly inform the operator of the safety status of the guide rails, effectively preventing equipment damage or safety accidents caused by improper operation.
