Description

Technical Field

[0001] The present invention relates to the field of surface radioactive contamination detection, and in particular to a throw-type radiation detector. Background Art

[0002] Radioactive radiation poses a serious threat to living things. Radiation damage can be acute or chronic. If a person is exposed to large doses of X-rays, gamma rays, and neutrons over a short period of time, acute damage can occur. Mild symptoms include hair loss and infection. Higher doses can cause gastrointestinal damage such as diarrhea and vomiting. Extremely high doses can cause central nervous system damage and even death. High-intensity radiation can burn the skin, cause leukemia and various cancers, disrupt reproductive functions, and, in severe cases, cause death within a short period of time.

[0003] Nuclear explosion areas, nuclear leakage accident areas, nuclear fuel mining areas and other places have extremely strong radioactivity. In order to avoid unnecessary harm to the human body due to radioactive radiation, it is very necessary to use a throw-type radiation detector to collect data on the radiation intensity and range of the radioactive area, demarcate the radioactive area, set up radioactive signs, and prevent people from accidentally entering the radioactive area and getting hurt.

[0004] The development of drone-based aerial surveying technology has laid the foundation for drop-type radiation detection. However, using drones to drop conventional radiation detectors can lead to serious problems such as incorrectly pointing the detector's wireless antenna, resulting in the inability to transmit and return detection data. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the prior art, ordinary radiation detectors, when dropped by drones, suffer from a serious problem in which the detection data cannot be transmitted and sent back due to incorrect pointing of the detector's wireless antenna.

[0006] The purpose of the present invention is to provide a throw-type radiation detector. The present invention designs a throw-type radiation detector with a double-shell floating fixed pointing structure, so that no matter whether the detector is thrown by a drone or other throwing methods, no matter whether it is thrown in a desert, next door, mountain or grassland, the inner shell and antenna of the detector always point to the set direction, laying a solid foundation for the transmission and return of radiation detection signals.

[0007] The present invention is achieved through the following technical solutions:

[0008] A projectile-type radiation detector, comprising a spherical inner shell and a spherical outer shell, wherein the spherical inner shell is arranged inside the spherical outer shell;

[0009] A radiation detection module is provided in the spherical inner shell, and the radiation detection module is used to complete the radiation detection and data transmission tasks of the radioactive area within a predetermined time;

[0010] A first medium - pure water - is provided at the lower part between the spherical outer shell and the spherical inner shell, and a second medium - air is provided at the upper part. The radiation detection module always floats in the first medium and points in a set direction, with the upper part facing upward, so that the antenna of the radiation detection module always points to the Beidou satellite.

[0011] As a further preferred solution, the radiation detection module includes a magnetic counterweight, a battery, a wireless transmission module, an industrial control mainboard, an antenna, and a detector;

[0012] The magnetic counterweight is provided at the bottom of the spherical inner shell, and the two ends of the magnetic counterweight are respectively an S pole and an N pole, so that the radiation detection module floating in the first medium has a set direction that always points to the south;

[0013] The battery is located directly above the magnetic counterweight and provides power to the wireless transmission module and the industrial control mainboard;

[0014] The wireless transmission module, industrial control mainboard, and detector are connected as a whole by a micro connector and are arranged directly above the battery. The antenna is arranged outside the top of the spherical inner shell and inside the spherical outer shell, and the antenna is connected to the wireless transmission module.

[0015] The detector collects information at the radiation site, processes it through the industrial control mainboard, and then transmits it remotely to a predetermined external receiving device via an antenna via a wireless transmission module for use by emergency personnel.

[0016] Specifically, after the processing and debugging of the radiation detection module is completed, the overall specific gravity of the radiation detection module is slightly lower than that of the first medium. The upper part of the radiation detection module is relatively light and the lower part is relatively heavy. Under the magnetic effect of the magnetic counterweight, it can not only float in the first medium of the spherical outer shell, but also the antenna is always facing upward and located in the second medium. The upper part of the radiation detection module is always facing upward and the antenna is always pointing to the Beidou satellite.

[0017] As a further preferred solution, the magnetic counterweight is made of a permanent magnet with magnetism, and its weight is carefully calculated so that the overall specific gravity of the radiation detection module is slightly lower than the first medium, and it can float in the first medium of the spherical outer shell.

[0018] As a further preferred solution, the antenna and the wireless transmission module are connected via a specially made coaxial cable; the coaxial cable passes through the top of the spherical inner shell, and the through hole is sealed.

[0019] As a further preferred solution, a foam sealing body is filled between the spherical inner shell and the radiation detection module, and the foam sealing body is used to completely wrap, fix and protect all components of the radiation detection module.

[0020] As a further preferred solution, the foam sealing body is formed by injecting a polyurethane foaming agent into the spherical inner shell, and the foaming agent forms an elastic solid foam sealing body after curing.

[0021] As a further preferred solution, the spherical inner shell and the spherical outer shell are both composed of two threaded hemispheres, and after the internal components are installed, they are connected by threads to form a complete sphere; and the threaded connection part is reinforced, bonded and sealed with a special adhesive, so that the connection part of the spherical shell has super connection and sealing performance.

[0022] As a further preferred embodiment, the spherical inner shell and the spherical outer shell are both made of high-strength polyurethane plastic. High-strength polyurethane plastic has low specific gravity, high tensile strength, certain elasticity, and is non-blocking to electromagnetic waves. Once formed into a sphere or a flying saucer, it cannot be smashed or broken, and does not affect radio signal transmission.

[0023] As a further preferred solution, the throwable radiation detector is suitable for the following throwing and spreading methods:

[0024] The first method of dropping and spreading: drones are airlifted to the radiation site for aerial dropping and spreading, forming a huge radiation detection network that can cover a huge radioactive contaminated area, detect radioactive data in the radioactive contaminated area, and transmit the data back to the command center via wireless transmission for use by radiation detection personnel.

[0025] The second method of spreading is spreading with a flying saucer projectile. When the throwing radiation detector is spread with a flying saucer projectile, a spherical throwing radiation detector is installed in a butterfly-shaped shell. It is more suitable for radioactive contaminated areas with relatively small areas and low radioactivity values. It is spread using a special flying saucer projectile or directly by humans.

[0026] The third method of throwing and spreading: direct manual spreading. When spread directly by hand, the butterfly-shaped throwing radiation detector can fly farther, cover a wider area, and be more efficient than the spherical throwing radiation detector. When thrown, it can fly farther like a flying saucer and land more steadily, which greatly cushions the impact force during landing and effectively protects the radiation detection module from damage.

[0027] The double-shell floating fixed-pointing structure throwable radiation detector of the present invention has a radiation detection module that always floats in the water, regardless of whether it is spread by a drone, a flying saucer projectile, or directly by humans, with the upper part facing upward and the antenna always pointing to the Beidou satellite. This solves the serious problem of the inability to transmit and send back detection data due to incorrect pointing of the detector's wireless antenna.

[0028] As a further preferred solution, the first medium is pure water, and the second medium is compressed air.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] 1. The present invention provides a throwable radiation detector, which is a double-shell floating throwable radiation detector with a fixed pointing structure. Regardless of whether the detector is thrown by a drone or other throwing methods, and regardless of whether it is thrown in a desert, next door, mountain or grassland, the inner shell and antenna of the detector always point to the set direction, and the antenna of the radiation detection module always points to the Beidou satellite, effectively avoiding the serious problem of the inability to transmit detection data due to incorrect antenna pointing.

[0031] 2. The present invention provides a throw-type radiation detector with a magnetic radiation detection module and antenna floating in a spherical outer shell. The radiation detection module and antenna are not only effectively protected by the elastic spherical outer shell, but also have extremely high horizontal stability and directional directivity.

[0032] 3. The throwable radiation detector of the present invention can be applied to various other equipment that require precise directional positioning, ultra-precision static level, good sealing performance, super strong structural strength, excellent bounce performance, and special use locations, and provides a solution for equipment with similar design requirements.

[0033] 4. The present invention provides a throw-type radiation detector having an elastic solid foam sealed spherical inner shell - a radiation detection module. It has high structural strength, good toughness, strong sealing performance, light weight, and super anti-fall ability. It is not afraid of being thrown from high altitudes, soaked in sewage, or exposed to wind, frost, rain, or snow.

[0034] 5. The present invention provides a throw-type radiation detector equipped with a butterfly-shaped housing, which has the advantages of being thrown farther, flying higher, landing more steadily, and providing better protection.

[0035] 6. The present invention provides a throw-type radiation detector that can collect data on radiation intensity and range in places such as nuclear explosion areas and nuclear leakage accident areas and transmit the data outside the nuclear contaminated area, providing a basis for calibrating the radiation intensity of the nuclear contaminated area and demarcating the scope of the nuclear contaminated area.

The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1

[0049] like Figures 1 to 3 As shown, the present invention provides a throw-type radiation detector, which includes a spherical inner shell 7 and a spherical outer shell 8. The spherical inner shell 7 is arranged inside the spherical outer shell 8.

[0050] The spherical inner shell 7 is provided with a radiation detection module, which is used to complete the radiation detection and data transmission tasks of the radioactive area within a predetermined time;

[0051] A first medium 11 is disposed below the spherical outer shell 8 and the spherical inner shell 7, and a second medium 10 is disposed above the spherical outer shell 8. The radiation detection module always floats in the first medium 11, pointing in a predetermined direction, with its upper portion facing upward, ensuring that the radiation detection module's antenna is always pointed toward the Beidou satellites. In practice, the first medium 11 is pure water, and the second medium 10 is compressed air.

[0052] In this embodiment, the radiation detection module includes a magnetic counterweight 1, a battery 2, a wireless transmission module 3, an industrial control mainboard 4, an antenna 5, and a detector 6;

[0053] The magnetic counterweight 1 is provided at the bottom of the spherical inner shell 7. The two ends of the magnetic counterweight 1 are respectively an S pole and an N pole, so that the radiation detection module floating in the first medium 11 has a set direction that always points to the south.

[0054] The battery 2 is located directly above the magnetic counterweight 1 and provides power to the wireless transmission module 3 and the industrial control mainboard 4;

[0055] The wireless transmission module 3, the industrial control mainboard 4, and the detector 6 are connected as a whole by a micro connector and are arranged directly above the battery 2. The antenna 5 is arranged outside the top of the spherical inner shell 7 and inside the spherical outer shell 8, and the antenna 5 is connected to the wireless transmission module 3.

[0056] The detector 6 processes the information collected at the radiation site through the industrial control mainboard 4 and then transmits the information remotely to a predetermined external receiving device through the wireless transmission module 3 and the antenna 5 for use by emergency personnel.

[0057] Through the above scheme, the radiation detection module and antenna with magnetism and floating in the spherical outer shell of the present invention are not only effectively protected by the elastic spherical outer shell, but also have extremely high horizontal stability and directional directivity.

[0058] Specifically, after the processing and debugging of the radiation detection module is completed, the overall specific gravity of the radiation detection module is slightly lower than that of the first medium 11. The upper part of the radiation detection module is relatively light and the lower part is relatively heavy. Under the magnetic effect of the magnetic counterweight 1, it can not only float in the first medium 11 of the spherical outer shell 8, but also the antenna 5 is always upward and located in the second medium 10. The upper part of the radiation detection module is always facing upward, and the antenna is always pointing to the Beidou satellite.

[0059] In this embodiment, the magnetic counterweight 1 is made of a permanent magnet with magnetism. Its weight is carefully calculated so that the overall specific gravity of the radiation detection module is slightly lower than the first medium 11 and it can float in the first medium 11 of the spherical outer shell 8.

[0060] In this embodiment, the antenna 5 is connected to the wireless transmission module 3 via a specially made coaxial cable; the coaxial cable passes through the top of the spherical inner shell 7, and the through hole is sealed.

[0061] In this embodiment, a foam sealing body 9 is filled between the spherical inner shell 7 and the radiation detection module. The foam sealing body 9 is used to completely wrap, fix and protect all components of the radiation detection module.

[0062] Through the above scheme, the elastic solid foam sealed spherical inner shell - radiation detection module has high structural strength, good toughness, strong sealing performance, light weight, and super anti-fall ability. It is not afraid of being thrown from high altitude, soaked in sewage, or wind, frost, rain or snow.

[0063] In this embodiment, the foam sealing body 9 is formed by injecting a polyurethane foaming agent into the spherical inner shell 7, and the foaming agent is cured to form an elastic solid foam sealing body.

[0064] In this embodiment, the spherical inner shell 7 and the spherical outer shell 8 are both composed of two threaded hemispheres, and after the internal components are installed, they are connected by threads to form a complete sphere; and the threaded connection part is reinforced, bonded and sealed with a special adhesive, so that the connection part of the spherical shell has super connection and sealing performance.

[0065] The radiation detection module is wrapped in the second medium 10 and the first medium 11 in the spherical outer shell 8, and is cushioned to a certain extent when it lands on the ground. In addition, the spherical outer shell 8, the spherical inner shell 7 and the foam sealing body 9 also have a certain elasticity and cannot be smashed or broken, thereby protecting the various components in the radiation detection module from damage.

[0066] The working principle is as follows: Conventional radiation detectors in the prior art, when dropped from drones, suffer from a serious problem where the detector's wireless antenna is incorrectly pointed, resulting in a failure to transmit and return detection data. The present invention provides a drop-type radiation detector, featuring a dual-shell floating fixed-pointing structure. A radiation detection module is housed within a spherical inner shell 7, configured to detect radiation in radioactive areas and transmit data within a predetermined timeframe. The radiation detection module comprises a magnetic counterweight 1, a battery 2, a wireless transmission module 3, an industrial control motherboard 4, an antenna 5, and a detector 6. The overall specific gravity of the radiation detection module is slightly lower than that of the first medium, allowing it to float within the first medium 11 of the spherical outer shell 8. The magnetic counterweight 1 has two ends, one of which is an S pole and the other is a N pole, respectively, allowing the radiation detection module, floating within the first medium 11, to function as a compass. The antenna 5 is always upward, located within the second medium 10. The radiation detection module always faces upward, with one side pointing south (the set direction), ensuring that the radiation detection module's antenna is always pointed toward the Beidou satellites.

[0067] The present invention provides a throwable radiation detector with a double-shell floating fixed-pointing structure. The detector's inner shell and antenna consistently point in the set direction, effectively resolving the problem of the antenna's inability to consistently point toward Beidou satellites. This provides a solid foundation for the transmission and return of radiation detection signals. The present invention can collect radiation intensity and range data from locations such as nuclear explosion zones and nuclear leak accident sites, and transmit this data outside the contaminated area, providing a basis for calibrating radiation intensity and demarcating the contaminated area.

[0068] During implementation, the components involved in the radiation detection module are first installed within the spherical inner shell 7. After the magnetic counterweight 1, battery 2, wireless transmission module 3, industrial control motherboard 4, antenna 5, and detector 6 are all installed and secured in their designated locations within the spherical inner shell 7, a polyurethane foam is injected. Once the foam cures, it forms an elastic, solid foam seal 9, which completely encapsulates, secures, and protects the aforementioned components, forming the radiation detection module. Next, after the radiation detection module is processed and debugged, its overall specific gravity is slightly lower than that of pure water. The upper portion of the module is relatively light, while the lower portion is relatively heavy. Due to the magnetic effect of the magnetic counterweight 1, it not only floats in the pure water within the spherical outer shell 8, but also maintains its upper portion facing upward, with the antenna 5 always pointing toward the Beidou satellites, within the compressed air. Next, the spherical outer shell 8 is assembled. Both the spherical inner shell 7 and the spherical outer shell 8 consist of two threaded hemispheres. After the internal components are installed, they are then threaded together to form a complete sphere. This completes the assembly, allowing subsequent casting and detection.

[0069] Example 2

[0070] like Figures 1 to 3 As shown, the difference between this embodiment and embodiment 1 is that the throwable radiation detector of the present invention is applicable to the following throwing and spreading methods:

[0071] The first method of dropping and spreading: drones are airlifted to the radiation site for aerial dropping and spreading, forming a huge radiation detection network that can cover a huge radioactive contaminated area, detect radioactive data in the radioactive contaminated area, and transmit the data back to the command center via wireless transmission for use by radiation detection personnel.

[0072] The second method of spreading by throwing: spreading by a flying saucer projectile. When the throwing radiation detector is spread by a flying saucer projectile, a spherical throwing radiation detector is installed in a butterfly-shaped shell 12. It is more suitable for radioactive contaminated areas with relatively small areas and low radioactivity values. It is spread by a special flying saucer projectile or directly by humans.

[0073] The third method of throwing and spreading: direct manual spreading. When spread directly by hand, the butterfly-shaped throwing radiation detector can fly farther, cover a wider area, and be more efficient than the spherical throwing radiation detector. When thrown, it can fly farther like a flying saucer and land more steadily, which greatly cushions the impact force during landing and effectively protects the radiation detection module from damage.

[0074] The double-shell floating fixed-pointing structure throwable radiation detector of the present invention has a radiation detection module that always floats in the water and points to the south, regardless of whether it is spread by a drone, a flying saucer projectile, or manually. The upper part faces upward, and the antenna always points to the Beidou satellite. This solves the serious problem of the inability to transmit and send back detection data due to incorrect pointing of the detector's wireless antenna.

[0075] In this embodiment, the spherical inner shell 7, the spherical outer shell 8, and the butterfly-shaped outer shell 12 are all made of high-strength polyurethane plastic. High-strength polyurethane plastic has the characteristics of low specific gravity, high tensile strength, certain elasticity, and no barrier to electromagnetic waves. After being made into a sphere or flying saucer, it cannot be smashed or broken, and does not affect radio signal transmission.

[0076] The present invention discloses a throwable radiation detector featuring a double-shell floating fixed-pointing structure. This allows the detector to be dropped from a drone or other drop methods, regardless of location, from a desert, a neighboring area, a mountain, or even a grassland. The detector's inner shell and antenna always point in the designated direction, and the radiation detection module's antenna always points toward the Beidou satellite. This effectively avoids the serious problem of incorrect antenna pointing preventing the transmission of detection data. In particular, the present invention's throwable radiation detector, equipped with a butterfly-shaped shell, offers the advantages of being thrown farther, flying higher, landing more stably, and providing enhanced protection.

[0077] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
