[0002] Civil air defense engineering (hereinafter referred to as civil defense engineering) refers to underground protective buildings constructed separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue during wartime, as well as basements built in conjunction with above-ground buildings that can be used for air defense during wartime. In civil defense buildings, air radioactivity monitoring instruments are used to monitor the building environment in real time. Air radioactivity monitoring instruments are important equipment used to detect the level of radioactive substances in the air in real time. They are widely used in nuclear power plants, research institutes, hospitals, public safety, civil defense engineering and other fields. Their main function is to monitor possible radioactive pollution in the air and ensure the safety of the civil defense environment and public health.

[0003] However, existing radioactive monitoring instruments are large in size and are usually placed in fixed locations within civil defense facilities for use and monitoring. This makes it inconvenient for testing personnel to move quickly between different locations such as civil defense buildings and refuge sites. Moving and transporting the detection device is also quite troublesome, and it is not possible to reach areas that may have exceeded the radioactive material limit in a timely manner to conduct inspections and take safety measures. Therefore, we propose a portable real-time detection device for civil defense to solve the above problems. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a portable real-time detection device for civil defense, including a radioactive monitoring instrument body 1, an air inlet pipe 2, and an air outlet pipe 3. The air inlet pipe 2 is located at the top of the radioactive monitoring instrument body 1. A cavity 4 is provided in the radioactive monitoring instrument body 1, and the air outlet pipe 3 is located in the cavity 4. A sealing cover 5 is hinged to the top of the radioactive monitoring instrument body 1. A gas collecting pipe 6 is fixedly connected to the top of the sealing cover 5. The bottom end of the gas collecting pipe 6 passes through the bottom of the sealing cover 5 and is fixed with a first sealing ring 7. An air supply component 8 for drawing air is provided in the cavity 4.

[0022] The overall effect of embodiment 1 is that the gas collection tube 6 integrates functionality and practicality. Users can lift the main body 1 of the radioactivity monitor by holding the gas collection tube 6, and move the main body 1 of the radioactivity monitor directly by lifting it. It can also be used with the air inlet tube 2 to introduce outside air into the main body 1 of the radioactivity monitor. The sealing cover 5, which can be opened and closed by the hinge, makes it convenient for personnel to inspect and assemble the main body 1 of the radioactivity monitor, which is very practical.

[0023] Example 2: As Figures 1-4As shown, the gas delivery assembly 8 includes an air pump 801 fixed to the bottom of the cavity 4, with a connecting pipe 802 fixedly connected to one end of the air outlet pipe 3 at the input end of the air pump 801; an air outlet hood 803 is fixedly fixed to one surface of the cavity 4, and a conduit 804 is fixedly connected to the output end of the air pump 801, with one end of the conduit 804 fixedly connected to one surface of the air outlet hood 803; an air outlet 805 communicating with the cavity 4 is opened on one surface of the radioactivity monitor body 1, the air outlet 805 is adapted to the air outlet hood 803, and a protective device is fixed in the air outlet 805. The top of the air inlet pipe 2 is fixed with a second sealing ring 9, and the first sealing ring 7 is in close contact with the second sealing ring 9. The bottom end of the gas collecting pipe 6 is aligned with the air inlet pipe 2. The gas collecting pipe 6 is L-shaped and has a certain degree of rigidity. The inner wall of the top end of the gas collecting pipe 6 is set in an inverted bucket shape. The top surface of the gas collecting pipe 6 is connected to a cover 10 by threads. A filter screen 11 is set in the middle of the cover 10. Temperature and humidity detectors 12 are respectively set on one side wall of the radioactivity monitoring instrument body 1. A display controller 13 is installed on one surface of the radioactivity monitoring instrument body 1.

[0024] The overall effect of Embodiment 2 is as follows: the air pump 801 generates suction in the channel of the radioactivity monitor body 1 and the air inlet pipe 2 through the connecting pipe 802, guiding outside air in, and then discharging the detected gas back into the outside through the conduit 804, the air outlet hood 803 and the air outlet 805. With the locking ring engaged, when the sealing cover 5 is closed, the first sealing ring 7 and the second sealing ring 9 are in close contact, and the air inlet pipe 2 and the gas collecting pipe 6 are connected. When the sealing cover 5 is open, the first sealing ring 7 and the second sealing ring 9 are not in contact, and the air inlet pipe 2 is not connected to the gas collecting pipe 6. The "L"-shaped gas collecting pipe 6 is easy for personnel to hold. The filter screen 11 can filter and retain impurities in the air, preventing them from entering the radioactivity monitor body 1 and affecting its service life. With the cooperation of the cover 10 and the thread, the cover 10 and the filter screen 11 can be easily cleaned or replaced. The temperature and humidity detector 12 can detect the temperature and humidity of the surrounding environment of the device and display the values ​​on the display controller 13.

[0025] Working principle: When in use, if personnel activate the main body 1 of the radioactivity monitor to detect air, the detection unit and air pump 801 begin to work. The input end of the air pump 801 creates a suction force, drawing outside air into the main body 1 of the radioactivity monitor through the air collection pipe 6 and the air inlet pipe 2. The air passes through the channels within the main body 1 and through various detection modules before being discharged from the air outlet pipe 3. The detected gas is then transported to the air outlet hood 803 through the connecting pipe 802 and the conduit 804, and subsequently discharged to the outside from the air outlet 805. The detection modules... The measured data is fed back to the display controller 13 and displayed. When personnel need to carry the main body 1 of the radioactive monitor, they can directly hold the gas collecting tube 6 and lift the main body 1 of the radioactive monitor to move it. It should be noted that the sealing cover 5 and the main body 1 of the radioactive monitor are respectively equipped with matching buckles and locking rings for fastening and limiting the sealing cover 5. Since it is a known technology, it is only shown in the figure and not described in detail in the text. The sealing cover 5 and the buckle and locking ring are set for convenience. When the sealing cover 5 is;

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the air pump 801, temperature and humidity sensor 12, and display controller 13 will not be explained in detail.
