[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0038] As marine pollution becomes increasingly serious, a large number of seafood may be contaminated by nuclear radiation. When people mistakenly eat these contaminated foods, it will pose a threat to their health. Most of the seafood that users bring home is stored in the refrigerator, but because it is impossible to distinguish which are contaminated seafood and which are not, all seafood are usually mixed in the refrigerator, which will cause seafood that has not been contaminated before to be contaminated by nuclear radiation.

[0039] The related technology provides a radiation-proof refrigerator for refrigerating nuclear medicine. A nuclear radiation probe is arranged on the wall of the refrigeration cavity. The function of the nuclear radiation probe is to detect the nuclear radiation in the refrigeration cavity so that the user can discover the nuclear radiation status of the items in the refrigerator in time.

[0040] However, the radiation-proof refrigerator for nuclear medicine refrigeration provided by relevant technologies can only detect the overall nuclear contamination situation inside the refrigerator, and cannot accurately detect the nuclear contamination situation of individual items. There is no way to distinguish the items in the refrigerator by accurately detecting the nuclear radiation values ​​of the items.

[0041] Combination Figures 1 to 4 As shown, an embodiment of the present disclosure provides a refrigerator to accurately detect the nuclear radiation value of each item in the refrigerator.

[0042] Optionally, the refrigerator includes an isolation box 30 and a nuclear radiation detection device 40. The isolation box 30 is arranged in the refrigerator and defines an isolation space; the nuclear radiation detection device 40 is arranged in the isolation space.

[0043] According to the disclosed embodiment, the isolation box 30 is arranged in the refrigerator, and the nuclear radiation detection device 40 is arranged in the isolation box 30. Before placing seafood and the like in the refrigerator, the user places the items suspected of being nuclear-contaminated in the isolation box 30, activates the nuclear radiation detection device 40, and performs accurate nuclear radiation detection on the items to be detected 20, and determines whether to place them in the refrigerator according to the nuclear contamination situation, thereby being able to timely discover and remove the nuclear-contaminated items.

[0044] The isolation box 30 can isolate the external environment from the internal environment of the isolation box 30. The object to be detected 20 and the nuclear radiation detection device 40 are placed together in the isolation box 30, which can prevent the external environment from interfering with the nuclear radiation detection and ensure the accuracy of the detection result.

[0045] Optionally, the isolation box 30 is arranged inside the refrigerator or outside the refrigerator.

[0046] During the nuclear radiation detection process, the object to be detected 20 is placed in the isolation box 30 for detection. The isolation box 30 is set inside the refrigerator, and the objects in the refrigerator can be placed in the isolation box 30 for nuclear radiation detection at any time, reducing the contact between the object to be detected 20 and the external environment. The objects to be placed in the refrigerator can also be placed in the isolation box 30 first, and after the detection is completed, it is determined whether to put them in the refrigerator according to the detection results.

[0047] Optionally, the isolation box 30 is arranged outside the refrigerator.

[0048] The nuclear radiation detection device 40 has a power output port, and needs to be connected to the power supply through the line during detection. The isolation box 30 is set outside the refrigerator for easy wiring. The user first puts the object 20 to be detected into the isolation box 30 for nuclear radiation detection, and determines whether to put it into the refrigerator based on the detection result. If the nuclear radiation pollution is serious, the object is directly removed without opening and closing the refrigerator door, reducing the number of opening and closing the refrigerator door, achieving energy saving and emission reduction, and preventing contamination of the items in the refrigerator.

[0049] Optionally, combined Figure 2 As shown, the refrigerator further includes a cabinet and a door 10. The door 10 is openably disposed on the cabinet, and the isolation box 30 is disposed on a side of the door 10 away from the cabinet.

[0050] By setting the isolation box 30 on the door 10, it is convenient to take out the items 20 to be tested from the refrigerator and directly put them into the isolation box 30, and unqualified products can be taken out of the refrigerator in time; it is also convenient to put the purchased products into the isolation box 30 for nuclear radiation detection first, and then determine whether to put them into the refrigerator according to the detection results. The isolation box 30 is set on the door 10 to reduce the distance from the refrigerator, thereby reducing the contact between the items 20 to be tested and the external environment, so as to avoid affecting the detection results.

[0051] Optionally, the door body 10 is provided with a mounting groove, and the isolation box body 30 is embedded in the mounting groove to fix the isolation box body 30 to the door body.

[0052] Optionally, the refrigerator further comprises a limit block, which is arranged on a side wall of the installation groove to limit the isolation box body 30 in the installation groove.

[0053] Optionally, the refrigerator further includes a hanging rack, one end of which is connected to the door body 10 , and the other end of which is connected to the isolation box body 30 , so that the isolation box body 30 is hung on the door body 10 .

[0054] It is understandable that the installation position and installation method of the isolation box 30 can be adjusted according to actual usage.

[0055] Optionally, combined Figure 1 As shown, an isolation layer 34 is provided on the inner wall of the isolation box 30 so that the isolation layer 34 covers the isolation space.

[0056] The isolation layer 34 is made of radiation-proof material, which refers to materials used to prevent or weaken radiation damage caused by various radioactive radiation sources.

[0057] According to the function and use part of radiation protection materials, they can be divided into two categories: anti-penetrating radiation materials and surface radiation protection materials. Anti-penetrating radiation materials include radiation-proof concrete, heavy metal materials such as lead and steel, ordinary concrete, clay brick masonry, compacted soil, graphite, radiation-proof glass, and radiation-proof rubber and plastic. Surface radiation protection materials include organic sheets, coatings, metal materials and inorganic non-metallic materials. In actual production applications, the material selection of the isolation layer 34 can be comprehensively considered based on production costs, production efficiency and other aspects.

[0058] According to the disclosed embodiment, the isolation box 30 defines an isolation space, and the isolation layer 34 covers the isolation space to separate the object to be detected 20 and the nuclear radiation detection device 40 in the isolation space from the external environment, thereby avoiding the influence of the external environment on the detection value.

[0059] In addition, when the object to be detected 20 has been nuclear contaminated, placing the object to be detected 20 in a detection device with an isolation layer 34 can prevent the object to be detected 20 from causing nuclear radiation contamination to the detection personnel or the surrounding environment.

[0060] Optionally, the isolation box 30 includes a box body 31 and a box door 32; the box door 32 is openably disposed on the box body 31 to open or close the box body 31, and is locked to the box body 31 during nuclear radiation detection.

[0061] Optionally, the refrigerator further includes a locking member, which is disposed on the door body 32 .

[0062] Optionally, the box body 31 is provided with a lock, and the locking member includes a lock tongue, and the lock tongue cooperates with the lock buckle so that the box door body 32 blocks the box body 31.

[0063] Optionally, the locking member includes a magnetic attraction portion.

[0064] The box body 31 and the box door body 32 are provided with positive and negative magnetic attraction parts, and the box door body 32 closes the box body 31 through the magnetic attraction.

[0065] By using the embodiment of the present disclosure, the object to be detected 20 is placed in the isolation box 30, and the box door 32 is closed by a locking member to isolate the isolation space from the external environment. Therefore, when the nuclear radiation detection device 40 is used to perform nuclear radiation detection on the object to be detected 20, the external environment can be prevented from interfering with the detection result, thereby ensuring the accuracy of the detection result.

[0066] Optionally, the isolation box body 30 further includes a connecting piece 33 , which is disposed between the box body 31 and the box door body 32 , so that the box door body 32 is connected to the box body 31 through the connecting piece 33 .

[0067] Optionally, the connection member 33 comprises a hinge.

[0068] By providing a hinge, the box door body 32 can be rotatably connected to the box body 31, so that the box door body 32 can open or close the box body 31.

[0069] Optionally, the connecting piece 33 is correspondingly arranged on the side of the box body 31 to enable the box door 32 to open or close the box body 31 in the left and right direction; and / or, the connecting piece 33 is correspondingly arranged on the top or bottom of the box body 31 to enable the box door 32 to open or close the box body 31 in the up and down direction.

[0070] Optionally, a hinge is provided on a side of the box body 31 , and the box door 32 is connected to the box body 31 via the hinge, so that the box door 32 can open or close the box body 31 in the left-right direction.

[0071] Optionally, a hinge is provided at the top or the bottom of the box body 31 so that the box door 32 can open or close the box body 31 in the up and down direction.

[0072] It is understandable that the location of the connecting member 33 can be set according to actual conditions.

[0073] Optionally, the box door body 32 includes a slide plate, and the slide plate is provided with a grip portion. The box body 31 is provided with a slide groove adapted to the slide plate, and the slide plate slides along the slide groove relative to the box body 31 to open or close the box body 31 using the slide plate.

[0074] By adopting the embodiment of the present disclosure, when the movable space of the refrigerator door is small, the isolation box body 30 is embedded in the door body 10, and the box body 31 is opened or closed by sliding a slide relative to the box body 31, which can reduce the space occupied by the isolation box body 30.

[0075] Optionally, the nuclear radiation detection device 40 includes a nuclear radiation sensor, and the sensor is arranged in the isolation space.

[0076] Nuclear radiation is also called ionizing radiation or radioactive substances. The energy emitted by radioactive substances in the form of waves or particles is called nuclear radiation. It is colorless and odorless, which means it cannot be seen or touched. We cannot sense its existence. We must use special instruments to measure and sense it. Nuclear radiation sensors refer to sensors that use radioactive isotopes for measurement.

[0077] The nuclear radiation detection device 40 uses a nuclear radiation sensor, which can accurately detect the nuclear radiation value in the isolation box 30.

[0078] In addition, the volume of the nuclear radiation sensor is smaller than that of other nuclear radiation detectors, which reduces the space occupied in the isolation box 30, thereby reducing the volume of the isolation box 30. More volume can be reserved in the isolation box 30 for placing the object 20 to be detected.

[0079] Optionally, there are one or more nuclear radiation detection devices 40 .

[0080] The number of nuclear radiation detection devices 40 can be controlled according to actual detection requirements.

[0081] Optionally, combined Figure 3 As shown, the object to be detected 20 is placed in the isolation space. When there are multiple nuclear radiation detection devices 40, multiple nuclear radiation detection devices 40 are arranged around the object to be detected 20.

[0082] Nuclear radiation is a process of energy transfer, and factors that affect nuclear radiation energy transfer include irradiation dose, location, direction, etc. When the object to be detected 20 has been nuclear contaminated, the nuclear radiation energy will be propagated in all directions. Therefore, when the nuclear radiation detection devices 40 are distributed in different positions, the detected nuclear radiation values ​​are different.

[0083] A plurality of nuclear radiation detection devices 40 are arranged around the object to be detected 20. The nuclear radiation detection values ​​of the object to be detected 20 by the nuclear radiation detection devices 40 in different directions and dimensions may be different. The highest value among the detection values ​​is taken as the nuclear radiation value of the object to be detected 20 to avoid detection errors.

[0084] Optionally, a plurality of nuclear radiation detection devices 40 are arranged symmetrically relative to the object to be detected 20 .

[0085] Exemplarily, a nuclear radiation detection device 40 is disposed in the up-down direction and the left-right direction of the object to be detected 20, so that multiple nuclear radiation detection devices 40 simultaneously perform nuclear radiation detection on the object to be detected 20, and the highest value of the detection value is taken.

[0086] Optionally, combined Figure 1 As shown, the nuclear radiation detection device 40 is provided with a mounting hole 41, and the inner wall of the isolation box 30 is provided with a mounting matching hole. Fastening bolts are used to pass through the mounting hole 41 and the mounting matching hole in sequence to fix the nuclear radiation detection device 40 in the isolation box 30.

[0087] Optionally, combined Figure 3 As shown, the refrigerator further includes a rotating platform 35 , which is disposed in the isolation box 30 and at the middle of the bottom wall of the isolation box 30 .

[0088] The nuclear radiation detection device 40 is disposed on the inner wall of the isolation box 30 and is disposed around the rotating platform 35 .

[0089] The object to be detected 20 is placed on the rotating table 35 so that the object to be detected 20 can rotate relative to the inner wall of the isolation box 30. During the rotation, the nuclear radiation detection device 40 is used to perform nuclear radiation detection on the object to be detected 20, and the highest value of the detection value is taken. In this way, the nuclear radiation value of each direction dimension can be accurately obtained to avoid detection errors.

[0090] Optionally, combined Figure 1 and Figure 4 As shown, the refrigerator also includes a display module 11, an alarm module 12 and a control module; the control module is connected to the nuclear radiation detection device 40, the display module 11 and the alarm module 12; the control module is used to obtain the detection value of the nuclear radiation detection device 40, and control the display module 11 to display the detection value, and when the detection value exceeds the threshold, the alarm module 12 is controlled to issue an alarm indication.

[0091] Optionally, the display module 11 is disposed on the door 10 of the refrigerator to display the nuclear radiation detection value of the object 20 to be detected.

[0092] Optionally, the alarm module 12 includes an alarm indicator light and a buzzer, and the alarm indicator light and the buzzer are arranged on the door body. When the detection result is normal, the alarm indicator light emits a green light prompt, and the buzzer does not work; when the detection result is abnormal, the alarm indicator light emits a red light prompt, and the buzzer emits a buzzing sound.

[0093] According to the embodiment of the present disclosure, the object to be detected 20 is placed in the isolation box 30, and the control module controls multiple nuclear radiation detection devices 40 to start simultaneously. After the detection is completed, the detection results of each nuclear radiation detection device 40 are obtained, and the control display module 11 is controlled to display the highest detection value. When the detection value is higher than the threshold of the national standard, the control module controls the alarm module 12 to issue a warning to remind the user in time.

[0094] Optionally, the refrigerator further includes a wireless communication module, and the wireless communication module is connected to the control module.

[0095] By providing a wireless communication module, when the object to be detected 20 is placed in the isolation box 30, the user can remotely control the detection to prevent the object to be detected 20 contaminated by nuclear matter from causing harm to the user during the detection.

[0096] The refrigerator provided by the embodiment of the present disclosure can achieve the following technical effects:

[0097] The refrigerator includes an isolation box 30 and a nuclear radiation detection device 40. The isolation box 30 is arranged in the refrigerator, and the nuclear radiation detection device 40 is arranged in the isolation box 30. The isolation box 30 is provided with an isolation layer 34 to prevent the external environment from affecting the nuclear radiation detection result.
