Description

Technical Field

[0001] The present invention relates to the technical field of environmental radiation monitoring, and particularly to an adaptive vehicle-mounted γ radiation survey system. Background Art

[0002] With the wide application of nuclear technology, nuclear safety issues have attracted more and more attention. Especially under the emergency conditions of nuclear and radiation accidents, higher requirements are put forward for the rapid response of environmental radiation monitoring in order to provide monitoring data and decision-making suggestions for nuclear emergencies.

[0003] Existing vehicle-mounted radiation survey systems are divided into two types. One is that the whole system is installed on a specific survey vehicle and is not disassembled daily, dedicated to a special vehicle; the other can be disassembled and installed on an ordinary civilian car, and the installation positions are generally on the roof, inside the car, and at the rear of the car. The existing technologies have the following disadvantages:

[0004] 1. The measurement height is unreasonable. According to the requirements in "General Monitoring Procedures in Case of Nuclear or Radiation Emergency" (IAEA-TECD OC-1092) and "Technical Specifications for Emergency Monitoring of Radiation Accidents" (HJ 1155-2020), the proposed γ radiation operation intervention level is the measurement result at 1 meter above the ground. The γ radiation measurement results at other positions need to be corrected to 1 meter above the ground before they can be applied. The correction process is technically difficult and time-consuming, which does not meet the immediacy and efficiency required for emergencies.

[0005] 2. The adaptability is insufficient. Currently, the common installation positions of vehicle-mounted radiation survey devices are on the roof, inside the car, and at the rear of the car. The installation methods on the roof and inside the car are fixed installations, which cannot flexibly adjust the installation position or be installed on different vehicles, and cannot deduct the shielding brought by the vehicle body itself to the radiation measurement device; the installation at the rear of the car or the fixed split installation method cannot be installed on different vehicles and the installation height is not adjustable, or it is installed on a lifter controlled by a driving motor, which increases the complexity of the system.

[0006] 3. The influence of temperature on radiation measurement equipment is not considered. Currently, when the vehicle-mounted survey system is working, the influence of outdoor high temperature on the working stability of the detector is generally not considered, and the stability of the monitoring results is poor.

[0007] 4. The response speed of the γ radiation measurement equipment is slow, which affects the measurement point density at the preset survey speed.

[0008] 5. The data results of the vehicle-mounted γ radiation monitoring system are generally displayed in the form of a survey path, and it is difficult to clearly describe the overall situation of the regional γ radiation level.

[0009] 6. It mainly works independently with a single set of system, and it is difficult to cooperate with multiple sets, and it cannot meet the requirements of the development trend perception of nuclear and radiation accident emergency areas.

[0010] Upon retrieval, the publication number: CN206002151U discloses an in-vehicle environmental emergency monitoring system, which cannot cooperate in multiple sets, does not consider outdoor high-temperature conditions, and does not determine a reasonable measurement height; the publication number: CN207008088U discloses a radiation environmental monitoring management system with unreasonable measurement height and insufficient adaptability.

[0033] As Figure 3As shown in the figure, the adaptive adjustment bracket 2 includes a fixed rod kit. The fixed rod kit, the adjustment rod 16, and the support rod 17 are sequentially connected to form a triangular structure. The open ends of the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20 in the fixed rod kit are connected by an anti-slip wire wrench. A shock-absorbing ring 15 is arranged in the middle of the U-shaped ends of the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20. A plurality of polypropylene bands 13 are arranged on the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20. The polypropylene bands 13 are connected to the rear of the vehicle through fixed buckles 14, and the shock-absorbing ring 15 is closely attached to one end face of the rear of the vehicle. The second U-shaped fixed rod 20 is connected to the adjustment rod 16. The adjustment rod 16 is divided into an inclined section and a horizontal section. The U-shaped end of the inclined section of the adjustment rod 16 is connected to the open end of the second U-shaped fixed rod 20 and is located above the first U-shaped fixed rod 11. The other end of the inclined section of the adjustment rod 16 is movably connected to the support rod 17. The support rod 17 is movably connected to the U-shaped end of the second U-shaped fixed rod 20. The adjustment rod 16 is connected to the support rod 17 through a universal buckle 14. A γ-ray survey device 1 is arranged above the horizontal section of the adjustment rod 16.

[0034] The fixed rod kit includes a first U-shaped fixed rod 11, a second U-shaped fixed rod 20, an anti-slip wire wrench 12, polypropylene bands 13, fixed buckles 14, and a shock-absorbing ring 15. As Figure 4 shown, the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20 pass through the grooves 28 on the anti-slip wire wrench 12 and are fixed to adaptively adjust the inclination angle and can be installed on the rear of different ordinary civilian cars. The anti-slip wire wrench 12 includes a connecting rod 22. The connecting rod 22 passes through the central holes of two oppositely arranged tooth discs 23 and fixes the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20 on the tooth discs 23 through a top seat 25 and a tail seat 24 respectively. One end of the connecting rod 22 is connected to the tail seat 24. The diameter of the tail seat 24 is larger than the diameter of the central hole of the tooth disc 23. The tooth discs 23 are arranged in opposite meshing. The other end of the connecting rod 22 passes through the top seat 25 and is movably connected to a handle 27 through a pin shaft 26. The diameter of the top seat 25 is larger than the diameter of the central hole of the tooth disc 23. Specifically, when the connecting rod 22 and the handle 27 are on the same straight line, the anti-slip wire wrench 12 is in a loosened state. At this time, rotate the two tooth discs 23 to adjust the meshing angle. After adjustment, press the handle 27 down to make the handle 27 perpendicular to the connecting rod 22. The top seat 25 and the tail seat 24 respectively press on the first U-shaped fixed rod 11 and the second U-shaped fixed rod 20 to achieve the purpose of locking and adjustment.

[0035] A shock-absorbing ring 15 is installed in the middle of the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20 to prevent scratching the vehicle body and achieve flexible fastening to the vehicle body and shock-absorbing effect. The polypropylene belt 13 with a fixed buckle 14 fixes the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20 to the rear of the vehicle from four directions: up, down, left, and right. The fixed buckle 14 is connected to the rear of the vehicle. The adjusting rod 16 is an integrated U-shaped stainless steel pipe. The opening end is fixed to the heat dissipation plate 10 by screws to fix the γ radiation survey device 1. The U-shaped end of the adjusting rod 16 is fixed to the first U-shaped fixing rod 11 by screws 21, and the inclination angle can be freely adjusted. There are two support rods 17 in total, each fixed to the second U-shaped fixing rod 20 and the adjusting rod 16 by two universal buckles 18. The universal buckles 18 can be easily adjusted in position fixed to the second U-shaped fixing rod 20 and the adjusting rod 16 by loosening and tightening, so that no matter what angle the adjusting rod 16 is adjusted to, the support rod 17 can provide rigid support. The 1-meter height-fixed rod 19 is a physical scale for providing a height of 1 meter above the ground for the γ radiation fast response detector 5 in the radiation survey device when adjusting the inclination angle of the adjusting rod 16.

[0036] The 1-meter height-fixed rod 19 serves as a physical scale to ensure that after the adaptive adjustment bracket 2 is installed, the measurement height of the γ radiation fast response detector 5 is 1 meter above the ground. The side of the carbon plate 9 with the module faces downward, and the heat dissipation plate 10 is fixedly connected above the opening end of the adjusting rod 16. The power module 8 is a rechargeable lithium battery.

[0037] The result analysis module 3 is used to analyze and display the survey results in real time, including a server and data analysis software. The server is communicatively connected to the γ radiation survey device 1 through the Internet TCP protocol and receives and stores data. The data analysis software analyzes and processes the survey data and displays the survey trajectory and hotspot contour map.

[0038] The data acquisition and reception module is used to receive the data sent by the γ radiation fast response detector 5 and the positioning module 7, pack the data, and transmit it to the result analysis module 3 through the mobile network. During the survey process, multiple sets of γ radiation survey devices 1 can work together. Each set of devices can perform different survey tasks respectively, can display the real-time survey trajectory and results simultaneously, and can make a γ radiation level contour map of the emergency area in real time, providing real-time pollution situation and decision-making suggestions for nuclear and radiation accident emergencies; it has significant efficiency advantages in large-scale regional radiation surveys.

[0039] Its usage method is as follows:

[0040] Step S1, adjust the anti-slip wire wrench 12 to change the inclination angle between the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20, and press the U-shaped ends of the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20 against the rear of the vehicle. Tighten the polypropylene belt 13 and use the fixed buckle 14 to fix and install it on the rear of the vehicle.

[0041] Step S2: Loosen the universal buckle 18, place the height-fixing rod 19 vertically at the bottom of the gamma radiation survey device 1, press the gamma radiation survey device 1 against the top of the height-fixing rod 19, keep the bottom surface of the gamma radiation survey device 1 parallel to the ground, and lock the universal buckle 18.

[0042] Step S3: After removing the height-fixing rod 19, the installation is completed. Turn on the gamma radiation survey device 1 and the result analysis module 3, start running, and obtain the survey trajectory and hot spot isogram from the data analysis software.

[0043] Specifically, when installing the adaptive adjustment bracket 2, first loosen the anti-slip wire wrench 12 between the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20, adjust the inclination angle to a position convenient for installation at the rear of an ordinary civilian car, and then tighten the anti-slip wire wrench 12. Then, use the fixing buckle 14 on the polypropylene belt 13 to buckle into the car assembly gap, and tighten the polypropylene belt 13 to firmly install the first U-shaped fixing rod 11 and the second U-shaped fixing rod 20 on the car tail. Loosen the four universal buckles 18 as needed, vertically stand the 1-meter height-fixing rod 19 at the bottom of the radiation survey device, and adjust the position of the adjusting rod 16 so that the radiation survey device 1 presses against the top of the 1-meter height-fixing rod 19. At this time, the height of the gamma radiation fast response measuring instrument 5 from the ground is 1 meter. Tighten the universal buckle 18 to fix the relative positions of the support rod 17, the second U-shaped fixing rod 20, and the adjusting rod 16. Remove the 1-meter height-fixing rod 19, and the installation is completed.
