Description

Technical Field

[0001] This utility model belongs to the field of safety protection technology, specifically involving an emergency alarm safety device for personnel trapped in a cold storage. Background Technology

[0002] In today's industrial production and logistics systems, cold storage facilities, as crucial facilities for storing goods with strict temperature requirements, are widely used in numerous fields such as food and medicine. Cold storage facilities typically maintain a low, stable temperature to ensure the quality and safety of stored goods. However, despite their critical role in production operations, the risk of personnel being trapped inside always exists. If an accident occurs and personnel are trapped inside a cold storage facility, prolonged exposure to the low temperature environment can lead to serious problems.

[0003] The extremely low temperatures inside cold storage facilities are a major factor affecting the safety of trapped individuals. Because the temperature inside cold storage is typically very low, body heat is rapidly lost. If trapped individuals remain in a cold storage facility for an extended period, their body temperature will drop rapidly. This rapid loss of body temperature can trigger a series of adverse physical reactions, such as chills, confusion, and slowed movement; in severe cases, it can even be life-threatening. Currently, safety measures for people trapped in cold storage facilities are inadequate. While existing alarm systems can promptly send out distress signals to notify outside personnel for rescue, they lack effective solutions for keeping trapped individuals warm while awaiting rescue. Until rescue arrives, trapped individuals are forced to endure the physical harm caused by hypothermia. Utility Model Content

The camera 11 can also be used for video calls with external rescue personnel, allowing them to directly see the condition of the trapped individuals and the actual conditions inside the cold storage. In practical scenarios, such as whether there are obstacles affecting rescue and the physical condition of the trapped person, more accurate and effective rescue strategies can be formulated. The voice speaker 1 is responsible for realizing two-way voice communication. On the one hand, after an emergency alarm, it can play pre-recorded prompts to guide the trapped person to perform subsequent operations and stabilize their emotions. On the other hand, the trapped person can communicate with external rescuers in real time through the voice speaker 1, informing them of their specific situation and the difficulties they are facing. Rescuers can also use the voice speaker 1 to comfort the trapped person and convey rescue progress and instructions to the trapped person to cooperate with the rescue operation.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wireless communication box 10 is located at the top center of the emergency alarm host 7. A temperature detection probe 9 is located on the left side of the wireless communication box 10, and an oxygen content detection probe 13 is located on the right side of the wireless communication box 10.

The temperature detection probe 9 on the left side of the wireless communication box 10 monitors the temperature data inside the cold storage in real time, and the oxygen content detection probe 13 on the right side monitors the oxygen content data. This data is transmitted to the rescue personnel through the wireless communication box 10, enabling them to fully understand the environmental conditions inside the cold storage and formulate a reasonable rescue plan. At the bottom of the emergency alarm host 7, multiple connectors are also equidistantly arranged. These connectors can be electrically connected to external power lines, network cables, audio cables, and video cables, respectively. The power line provides stable power support for the device to ensure normal operation. The network cable is used to achieve high-speed data transmission and ensure the stable transmission of alarm information, video images, and other data. The audio and video cables are responsible for the transmission of voice and video signals, respectively, ensuring the quality of two-way communication and image transmission.

[0026] like Figure 1 , Figure 5 and Figure 6As shown, safety devices 4 are installed on the lower sides of the center of both the left and right ends of the emergency alarm host 7. The safety devices 4 include a blower box 17, an air inlet protective mesh 18, a cuboid electric heating box 19, a high-temperature resistant corrugated duct 20, and an electric heating wire mesh 21. The cuboid electric heating box 19 is fixed to the outer walls of both the left and right ends of the emergency alarm host 7, and is flush with the bottom outer wall of the emergency alarm host 7. Air inlets and outlets are respectively provided inside the upper and lower ends of the cuboid electric heating box 19. The blower box 17 is fixed to the top of the cuboid electric heating box 19 by flanges and screws. The blower box 17 has openings at both the upper and lower ends, with the openings being an air inlet and an air outlet, respectively. The diameter of the air outlet is larger than that of the air inlet at the top of the cuboid electric heating box 19. The blower box 17 communicates with the interior of the cuboid electric heating box 19 through the air outlet and air inlet. The device 4 also includes a control box 14, a fan speed and temperature adjustment knob 15, and a connecting wire 16. The control box 14 is fixed to the outer wall of the front end of the cuboid electric heating box 19.

A blower is fixed inside the blower box 17 by a frame, and the blower generates downward airflow when it is running. Air enters from the air intake at the top of the blower box 17 and is blown out through the air outlet. Since the diameter of the air outlet is larger than the air intake at the top of the cuboid heating box 19, this design helps the air to enter the cuboid heating box 19 smoothly, ensuring the high efficiency of air transmission. A high-temperature resistant corrugated air duct 20 is fixed to the outside of the air outlet at the bottom of the cuboid heating box 19. The corrugated duct 20 can be adjusted in any direction and at a large angle, which allows trapped personnel to flexibly adjust the direction of the hot air according to their own needs and actual location, directing the hot air towards the parts of their body that need warmth. In this way, warmth can be provided to trapped personnel more precisely and the warming effect can be improved. The cube-shaped electric heating box 19 is equipped with multiple electric heating wire meshes 21. When current passes through the electric heating wire meshes 21, electrical energy is converted into heat energy, thereby heating the air entering the cube-shaped electric heating box 19. The air inlet and air outlet are respectively set at the upper and lower ends of the cube-shaped electric heating box 19, realizing the orderly circulation of air, so that the heated air can be continuously discharged from the air outlet.
