Description

Technical Field

[0001] This application relates to the field of radioactive contamination detection technology, specifically to an automatic detection device for the degree of radioactive contamination. Background Technology

[0002] Radioactive contamination detection technology has significant applications in fields such as nuclear energy utilization and medical radiation. With the rapid development of the nuclear energy industry, the demand for radioactive contamination detection is increasing daily. Currently, technological development in this field mainly focuses on improving detection accuracy, reducing detection costs, and achieving automated detection.

[0003] Currently, the detection of radioactive contamination levels is usually done manually with handheld detection instruments, which can affect the health of the personnel being tested. The detection range is also limited, and automatic detection cannot be performed for extended periods. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automatic detection device for the degree of radioactive contamination. This device has the advantages of eliminating the need for manual handheld detection instruments to enter radioactive contamination areas, thus preventing harm to the health of detection personnel. It also has a wide detection range and can perform automatic detection for extended periods. This solves the problems that current methods for detecting the degree of radioactive contamination typically involve manual handheld detection instruments, which can harm the health of detection personnel, have a limited detection range, and cannot perform automatic detection for extended periods.

[0005] To achieve the aforementioned goals of eliminating the need for manual entry of detection instruments into radioactive contamination areas, preventing harm to the health of detection personnel, providing a wide detection range, and enabling long-term automatic detection, this application provides the following technical solution: an automatic detection device for the degree of radioactive contamination, comprising a detection module, wherein the detection module includes a radiation sensor, a signal transmitter is disposed on one side of the radiation sensor, the radiation sensor is electrically connected to the signal transmitter, the radiation sensor transmits signals to a signal receiver through the signal transmitter, the signal receiver is disposed on one side of a data processing host, the signal receiver is electrically connected to the data processing host, and the data processing host has a built-in data processor and memory.

[0006] The detection module is mounted on the bottom of the traveling vehicle via a connecting component. The traveling vehicle is located inside the suspended rail. Two traveling wheels are provided on both sides of the traveling vehicle. The outer surface of the middle part of the traveling wheel contacts the bottom of the inner wall of the suspended rail. The suspended rail is mounted on the indoor ceiling where the detection is required.

[0007] The above scheme uses a radiation sensor to detect radiation values. The detected values ​​are transmitted to a data processing host via a signal transmitter and receiver for analysis. A traveling trolley with wheels moves within a suspended rail to adjust the position of the detection module, enabling it to perform large-scale detection within the required area. This eliminates the need for manual personnel to enter radioactive contamination areas, preventing harm to the health of testing personnel. The system offers a wide detection range and allows for long-term automated detection.

[0008] Furthermore, a signal amplifier is provided on one side of the signal transmitter, and the signal transmitter is electrically connected to the signal amplifier.

[0009] The above solution enhances the signal strength acquired by the radiation sensor, preventing data transmission interruptions caused by the distance between the detection module and the data processing host or by electromagnetic interference indoors, thus ensuring the real-time performance and accuracy of the detection results.

[0010] Furthermore, the connecting assembly includes a connecting rod, one end of which is located at the bottom of the traveling vehicle, and the other end of which extends from the inside of the suspended rail through a through groove opened along the track at the bottom of the suspended rail to the bottom of the suspended rail. An electric telescopic rod is provided between the connecting rod and the radiation sensor. One end of the telescopic outer tube of the electric telescopic rod is located at the end of the connecting rod away from the traveling vehicle, and one end of the telescopic inner tube of the electric telescopic rod is located at the top of the radiation sensor.

[0011] The above solution allows the radiation sensor to move vertically via the operation of the electric telescopic rod, which adjusts the vertical height of the detection module and increases the detection range of the radiation sensor.

[0012] Furthermore, the walking wheel includes an inner support wheel, and an anti-slip sleeve is provided on the outer surface of the middle part of the inner support wheel. The anti-slip sleeve is made of anti-slip rubber material.

[0013] Through the above solution, the anti-slip sleeve made of anti-slip rubber material can increase the friction between the traveling wheel and the inner wall of the hanging rail, causing slippage between the traveling wheel and the bottom of the inner wall of the hanging rail, ensuring that the detection module can be stably adjusted in position by the traveling wheel and the traveling vehicle in conjunction with the hanging rail.

[0014] Furthermore, a display is provided on the top of the data processing host.

[0015] With the above solution, the display can show data such as radiation dose rate, detection point coordinates, and historical data curves in real time, making it convenient for on-site personnel to intuitively monitor the detection situation.

[0016] Furthermore, an alarm is installed on one side of the data processing host, and the alarm is an audible and visual alarm.

[0017] With the above scheme, when the radiation dose rate exceeds the preset threshold, the alarm can issue an audible and visual alarm and link the data processing host to start the emergency recording mode, which can quickly remind staff to carry out emergency plans.

[0018] Furthermore, the hanging rail is arranged in a serpentine pattern.

[0019] The above solution extends the movement trajectory of the trolley-driven detection module by using a serpentine arrangement of the overhead rails, increasing the detection range of the detection module within spaces requiring detection and ensuring the detection accuracy of the module within those spaces.

[0020] Furthermore, the top of the traveling vehicle is provided with a limit rod, and two limit discs are provided on the outer surface of one end of the limit rod. The outer surface of the two limit discs on opposite sides is slidably connected to the top and bottom outer surfaces of the limit strip. There are two limit strips, which are located on both sides of the limit rod and on both sides of the inner wall of the hanging rail.

[0021] The above solution, through the cooperation of two limiting discs and limiting strips, can prevent the vehicle from tipping over or shaking violently during movement, ensuring that the detection module always maintains a horizontal posture and avoiding the detection angle deviation of the radiation sensor due to tilting.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This automatic radioactive contamination detection device detects radiation values ​​using radiation sensors. The detected values ​​are transmitted to a data processing host via a signal transmitter and receiver for analysis. A trolley with wheels moves along a suspended rail to adjust the position of the detection module, allowing it to perform large-scale detection within the required area. This eliminates the need for manual entry of the detection instrument into the radioactive contamination zone, preventing harm to the health of the detection personnel. It offers a wide detection range and can perform automatic detection over extended periods. Attached Figure Description

The hanging rail 9 is set on the indoor ceiling where the detection is required.

[0034] Please see Figure 1 , Figure 2 and Figure 3A signal amplifier 103 is provided on one side of the signal transmitter 102. The signal transmitter 102 and the signal amplifier 103 are electrically connected. The signal amplifier 103 can enhance the signal strength collected by the radiation sensor 101, and avoid data transmission interruption when the detection module 1 is far away from the data processing host 2 or when there is electromagnetic interference indoors, so as to ensure the real-time performance and accuracy of the detection results.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The connecting component 5 includes a connecting rod 502. One end of the connecting rod 502 is located at the bottom of the traveling vehicle 6, and the other end of the connecting rod 502 extends from the inside of the hanging rail 9 through a through groove opened along the track of the hanging rail 9 to the bottom of the hanging rail 9. An electric telescopic rod 501 is provided between the connecting rod 502 and the radiation sensor 101. One end of the telescopic outer tube of the electric telescopic rod 501 is located at the end of the connecting rod 502 away from the traveling vehicle 6, and one end of the telescopic inner tube of the electric telescopic rod 501 is located at the top of the radiation sensor 101. The operation of the electric telescopic rod 501 can drive the radiation sensor 101 to move vertically, which can adjust the vertical height of the detection module 1 and improve the detection range of the radiation sensor 101.

[0036] Please see Figure 5 The traveling wheel 7 includes an inner support wheel 701. An anti-slip sleeve 702 is provided on the outer surface of the middle part of the inner support wheel 701. The anti-slip sleeve 702 is made of anti-slip rubber. The anti-slip sleeve 702 made of anti-slip rubber can increase the friction between the traveling wheel 7 and the inner wall of the hanging rail 9. Slippage occurs between the bottom of the traveling wheel 7 and the inner wall of the hanging rail 9, ensuring that the detection module 1 can be stably adjusted in position by the traveling wheel 7 and the traveling vehicle 6 in conjunction with the hanging rail 9.

[0037] Please see Figure 1 and Figure 2 The top of the data processing host 2 is equipped with a display 3, which can display data such as radiation dose rate, detection point coordinates, and historical data curves in real time, making it convenient for on-site personnel to intuitively monitor the detection situation.

When the radiation dose rate exceeds the preset threshold, the alarm 4 can issue a sound and light alarm and link the data processing host 2 to start the emergency recording mode, which can quickly remind the staff to carry out emergency plans.

[0039] Please see Figure 1 , Figure 2 and Figure 4The hanging rail 9 is designed in a serpentine pattern. The serpentine pattern of the hanging rail 9 can extend the movement trajectory of the traveling vehicle 6 driving the detection module 1, increase the detection range of the detection module 1 in the space where detection is required, and ensure the detection accuracy of the detection module 1 in the space where detection is required.

[0040] Please see Figure 2 , Figure 4 and Figure 5 The top of the traveling vehicle 6 is equipped with a limit rod 11. Two limit discs 12 are arranged vertically on the outer surface of one end of the limit rod 11. The outer surfaces of the two limit discs 12 on opposite sides are slidably connected to the top and bottom outer surfaces of the limit strips 10. There are two limit strips 10, which are located on both sides of the limit rod 11 and on both sides of the inner wall of the hanging rail 9. The cooperation between the two limit discs 12 and the limit strips 10 can prevent the traveling vehicle 6 from tipping over or shaking violently during movement, ensuring that the detection module 1 always maintains a horizontal posture and avoiding the detection angle deviation of the radiation sensor 101 due to tilting.

[0041] This embodiment of an automatic radioactive contamination detection device detects radiation values ​​using a radiation sensor 101. The detected values ​​are transmitted to a data processing host 2 via a signal transmitter 102 and a signal receiver 8 for analysis and processing. The device moves within a suspended rail 9 using a traveling trolley 6 and traveling wheels 7, adjusting the position of the detection module 1 to enable it to perform large-scale detection within the required area. This eliminates the need for manual entry of the detection instrument into the radioactive contamination zone, preventing harm to the health of the detection personnel. The device also offers a wide detection range and allows for long-term automatic detection.

[0042] The working principle of the above embodiment is as follows: The radiation value in the target area is detected by the radiation sensor 101 of the detection module 1. The detected value is transmitted through the signal transmitter 102. The signal amplifier 103 amplifies the intensity of the transmitted signal. The signal transmitter 102 transmits the detected value to the signal receiver 8. The data processing host 2 processes the signal received by the signal receiver 8. The data processor in the data processing host 2 processes and analyzes the detected value. The display 3 displays the real-time detected value of the target area. When the radiation value exceeds the preset threshold, the alarm 4 starts to sound and light alarm. During detection, the traveling vehicle 6 moves along the track of the hanging rail 9 through the traveling wheels 7. The traveling vehicle 6 drives the detection module 1 to move in the target area through the connecting component 5. The detection position of the detection module 1 in the target area is adjusted. When the traveling vehicle 6 moves, the outer surface of the opposite side of the upper and lower limit plates 12 slides on the top and bottom outer surfaces of the limit strip 10, which limits the angle of the traveling vehicle 6. The electric telescopic rod 501 can drive the detection module 1 to move vertically up and down. The detection height of the detection module 1 can be adjusted according to the detection requirements.
