Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold storage technology, and in particular to a biomedical cold storage with a fire detection agency. Background Technology
[0002] A biomedical cold storage facility is a specialized cold storage unit used to store biological samples, vaccines, pharmaceuticals, and other medical supplies that require preservation at extremely low temperatures, typically around -70°C. This type of cold storage has wide applications in the biomedical field, ensuring the long-term stability and safety of stored items.
[0003] Most existing biomedical cold storage facilities use relatively traditional fire detection systems, such as ordinary smoke detectors and temperature sensors. These devices are easily affected by the temperature inside the cold storage, resulting in low sensitivity. Due to the low sensitivity of the devices, the smoke or temperature changes generated in the early stages of a fire may not be enough to trigger an alarm, leading to a delay in fire detection. This will make it difficult for personnel evacuation and fire fighting, and increase the losses caused by the fire. Utility Model Content
[0004] The purpose of this invention is to provide a biomedical cold storage facility with a fire detection mechanism. This device facilitates fire detection inside the cold storage facility, thus solving the problem of inconvenient fire detection inside cold storage facilities in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A biomedical cold storage with a fire detection mechanism includes a storage body, a shell fixedly connected to the top of the storage body, a smoke sensor and a temperature sensor fixedly connected to the top of the shell, an air inlet through one side of the shell, and an exhaust outlet through the other side of the shell; two pipes, with two protrusions fixedly connected to the upper ends of the pipes, the upper ends of the protrusions being fixedly connected to the top of the storage body, the two pipes being located on opposite sides of the shell, one pipe port communicating with the air inlet, and the other pipe port communicating with the exhaust outlet, and a heater fixedly connected inside one of the pipes.
[0007] Preferably, a side door is rotatably connected to the side wall of the storage body, and a handle is fixedly connected to the side wall of the side door.
[0008] Preferably, a first insulation layer is fixedly connected to the inside of the shell sidewall, and a second insulation layer is fixedly connected to the inside of the pipe sidewall.
[0009] Preferably, a controller is fixedly connected to the bottom of the housing, and the controller is electrically connected to the smoke sensor and the temperature sensor respectively.
[0010] Preferably, one of the pipes has multiple rods fixedly connected in a ring array on its inner wall, and the ends of the multiple rods are fixedly connected to a mounting plate, with a motor fixedly connected to the side wall of the mounting plate.
[0011] Preferably, a crossbar is rotatably connected through the side wall of the mounting plate, and multiple blades are fixedly connected to the side wall of the crossbar. The multiple blades are arranged in a circular array, and the motor output end is fixedly connected to the end of the crossbar.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. Cold air inside the storage tank is guided into the tank through an airflow pipe. The air is heated to a temperature below the set value of the temperature sensor by an internal heater. The heated air then enters the housing through the air inlet. Smoke and temperature sensors detect smoke particles and temperature in the air, enabling real-time fire monitoring inside the storage tank. By monitoring smoke particles and temperature inside the storage tank in real time, an alarm can be issued quickly once an anomaly is detected, providing valuable time for personnel evacuation and fire fighting.
[0014] 2. The cold air is heated to a temperature below the set value of the temperature sensor by a heater inside one of the pipes. Heating the cold air prevents it from directly affecting and damaging the smoke sensor and temperature sensor when it enters the housing later. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A biomedical cold storage with a fire detection mechanism includes a storage body 001, a shell 002 fixedly connected to the top of the storage body 001, a smoke sensor 202 and a temperature sensor 203 fixedly connected to the top of the shell 002, an air inlet 204 penetrating one side of the shell 002 and an exhaust 205 penetrating the other side of the shell 002; two pipes 003, two protrusions 308 fixedly connected to the upper end of the pipes 003, the upper ends of the protrusions 308 being fixedly connected to the top of the storage body 001, the two pipes 003 being located on both sides of the shell 002, one pipe 003 having its port connected to the air inlet 204, and the other pipe 003 having its port connected to the air inlet 204. The air is connected to the exhaust port 205. A heater 301 is fixedly connected inside one of the pipes 003. The cold air inside the storage body 001 is guided into the body through the airflow inside one of the pipes 003. The heater 301 inside the body heats the cold air to a temperature below the set value of the temperature sensor 203. Then the hot airflow enters the housing 002 through the air inlet 204. The smoke sensor 202 and the temperature sensor 203 detect the smoke particles and temperature in the air, thereby performing real-time fire detection inside the storage body 001. The detected air flows through the exhaust port 205 into another pipe 003 and is discharged.
[0023] A side door 101 is rotatably connected to the side wall of the storage body 001. A handle 102 is fixedly connected to the side wall of the side door 101. By holding the handle 102 with one's hand and then pulling or pushing the handle 102, the side door 101 is rotated, thereby opening or closing the opening end of the storage body 001.
[0024] The inner side wall of the shell 002 is fixedly connected to the insulation layer 201, and the inner side wall of the pipe 003 is fixedly connected to the insulation layer 302. Both the insulation layer 201 and the insulation layer 302 are made of polyurethane foam.
[0025] A controller 206 is fixedly connected to the bottom of the housing 002. The controller 206 is electrically connected to the smoke sensor 202 and the temperature sensor 203 respectively. An external alarm is fixedly connected to the rear side of the storage body 001. The external alarm is electrically connected to the controller 206. When the smoke sensor 202 and the temperature sensor 203 detect that there is a large amount of smoke in the air and the temperature is greater than the rated value, they send a signal to the controller 206. Then the controller 206 sends a signal to the external alarm, causing the external alarm to sound an alarm.
[0026] One of the pipes 003 has multiple rods 303 fixedly connected in a ring array on its inner wall. The ends of the multiple rods 303 are fixedly connected to a mounting plate 304. A motor 305 is fixedly connected to the side wall of the mounting plate 304. The motor 305 is supported by the multiple rods 303 and the mounting plate 304.
[0027] A crossbar 306 is rotatably connected through the side wall of the mounting plate 304. Multiple blades 307 are fixedly connected to the side wall of the crossbar 306. The multiple blades 307 are arranged in a ring array. The output end of the motor 305 is fixedly connected to the end of the crossbar 306. The output end of the motor 305 drives the crossbar 306 to rotate. At the same time, the crossbar 306 drives the multiple blades 307 to rotate, thereby generating a guiding airflow inside one of the pipes 003.
[0028] In this invention, the output end of the motor 305 drives the crossbar 306 to rotate, and the crossbar 306 drives multiple blades 307 to rotate, causing a guiding airflow to be generated inside one of the pipes 003. The -70°C cold air inside the storage body 001 is guided into its interior through the airflow inside one of the pipes 003. The heater 301 inside the storage body heats the -70°C cold air to a temperature below the set value of the temperature sensor 203. Then, the hot airflow enters the interior of the housing 002 through the air inlet 204. The smoke sensor 202 and the temperature sensor 203 detect the smoke particles and temperature in the air, thereby performing real-time fire detection inside the storage body 001. The detected air flows into another pipe 003 through the exhaust port 205 and is discharged.
[0029] When the smoke sensor 202 and the temperature sensor 203 detect that there is a large amount of smoke in the air and the temperature is greater than the rated value, they send a signal to the controller 206. Then the controller 206 sends a signal to the external alarm, causing the external alarm to sound an alarm.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
