Description

Technical Field

[0001] This utility model relates to the field of radiation dose rate meter technology, and in particular to a detachable probe for a radiation dose rate meter. Background Technology

[0002] Gamma dose rate meters, as important devices for measuring gamma-ray radiation dose rate in the environment, have wide applications in many fields such as nuclear energy utilization, radiation environment monitoring, medical radiation protection, and industrial non-destructive testing. Currently, commercially available gamma dose rate meters have several limitations in radiation dose measurement. Traditional gamma dose rate meters are mostly handheld or fixed in design. While handheld devices are convenient to carry, in some special scenarios, such as high-radiation areas, confined spaces, or environments containing hazardous materials, operators find it difficult to approach the measurement point. This not only affects the accuracy of the measurement results but may also pose a threat to the operator's health.

[0003] To address the aforementioned issues, some existing measuring instruments increase the measurement distance by extending the measuring rod, thus solving the problem of operators being unable to approach the measurement point. However, in existing long-rod dose rate meters, the probe is directly connected to the main unit via a data transmission cable, making it impossible to quickly change the probe with the appropriate range according to different working environments, and thus unable to adapt to different measurement loops. Utility Model Content

[0004] The purpose of this invention is to provide a detachable probe for a radiation dose rate meter, thereby solving the technical problem in existing radiation dose rate meters where it is inconvenient to quickly replace the probe as needed. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a detachable probe for a radiation dose rate meter, comprising a probe protective housing, a plug protective housing, a Geiger-Müller counter tube, a circuit board, a female connector, and a male connector. The probe protective housing includes a first housing and a second housing that are detachably connected. The Geiger-Müller counter tube is installed in the first housing, and the circuit board and the female connector are installed in the second housing. The Geiger-Müller counter tube and the circuit board are electrically connected via a connector port, and the circuit board is electrically connected to the female connector. The first end of the plug protective housing is detachably connected to the second housing. The male connector is rotatably installed in the plug protective housing so that it is inserted into the female connector. The end of the plug protective housing away from the probe protective housing is inserted into the measuring rod of the radiation dose rate meter, and the male connector is electrically connected to a first wire and a second wire in the measuring rod.

[0007] Preferably, a retaining ring connected by a thread is provided on the inner sidewall of the second housing, and the aircraft plug head is installed in the retaining ring.

[0008] Preferably, a plurality of operating holes are provided on the end face of the fixing ring.

[0009] Preferably, the plug protective housing includes a detachably connected first connecting part and a second connecting part, the male connector of the aircraft plug is installed in the first connecting part, the diameter of the second connecting part is smaller than that of the first connecting part, and the first wire passes through the second connecting part and connects to the measuring rod of the radiation dose rate meter.

[0010] Preferably, a bearing is provided between the male connector and the first connecting part.

[0011] Preferably, the first connecting part and the probe protective housing are connected by a thread or a plug.

[0012] Preferably, when the first connecting part and the probe protective housing are plugged in, a locking member connected by a thread is provided on the outside of the first connecting part and the probe protective housing.

[0013] The technical solution provided in this application document has the following beneficial effects:

[0014] This invention provides a detachable probe for a radiation dose rate meter, comprising a probe protective housing, a plug protective housing, a Geiger-Müller counter tube, a circuit board, a female connector, and a male connector. The Geiger-Müller counter tube, circuit board, and female connector are installed inside the probe protective housing, while the male connector is installed inside the plug protective housing. The first end of the plug protective housing is detachably connected to the second housing. During use, the male connector can be installed on the female connector, facilitating the replacement of different probe protective housings. This allows users to quickly change probe protective housings of different lengths to adapt to different measurement environments.

[0015] The probe protective housing includes a detachably connected first housing and a second housing. The first housing and the second housing can be connected by plug-in or threaded connection. The Geiger-Müller counter is installed in the first housing, and the circuit board and the female connector are installed in the second housing. The female connector is located at the end of the second housing away from the first housing. The Geiger-Müller counter, circuit board, and female connector are electrically connected in sequence. The Geiger-Müller counter and the circuit board are electrically connected through a connector. The probe protective housing is designed as a split structure to facilitate the assembly, maintenance, and replacement of internal components. However, the connection between the first housing and the second housing is not limited to these two methods. As long as they can be detached and connected, it is acceptable. This allows users to choose different lengths of the first housing to ensure accurate detection by the Geiger-Müller counter.

[0016] Furthermore, the male connector is rotatably installed inside the plug protective housing so that it can be inserted into the female connector. The end of the plug protective housing away from the probe protective housing is inserted into the measuring rod of the radiation dose rate meter.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This specific embodiment provides a detachable probe for a radiation dose rate meter, which solves the technical problem in the prior art that radiation dose rate meters are not convenient for quick probe replacement as needed.

[0025] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0026] Reference Figures 1-4 This utility model provides a detachable probe for a radiation dose rate meter, including a probe protective housing 1, a plug protective housing 2, a Geiger-Müller counter tube 3, a circuit board 4, a female connector 5, and a male connector 6. The Geiger-Müller counter tube 3, the circuit board 4, and the female connector 5 are installed inside the probe protective housing 1, and the male connector 6 is installed inside the plug protective housing 2. The first end of the plug protective housing 2 is detachably connected to the second housing 12. When in use, the male connector 6 can be installed on the female connector 5, which facilitates the replacement of different probe protective housings 1. This allows users to quickly replace probe protective housings 1 of different lengths according to different situations to adapt to different measurement environments.

[0027] The probe protective housing 1 includes a detachably connected first housing 11 and second housing 12. The first housing 11 and the second housing 12 can be connected by plug-in or threaded connection. The Geiger-Müller counter tube 3 is installed in the first housing 11, and the circuit board 4 and the female connector 5 are installed in the second housing 12. The female connector 5 is located at the end of the second housing 12 away from the first housing. The Geiger-Müller counter tube 3, the circuit board 4, and the female connector 5 are electrically connected in sequence, and the Geiger-Müller counter tube 3 and the circuit board 4 are electrically connected through a connector. The probe protective housing 1 is designed as a split structure to facilitate the assembly, maintenance, and replacement of internal components. However, the connection between the first housing 11 and the second housing 12 is not limited to these two methods. As long as they can be detached and connected, different lengths of the first housing 11 can be selected according to the situation so that the Geiger-Müller counter tube 3 can accurately detect.

[0028] Furthermore, the male connector 6 is rotatably mounted inside the plug protective housing 2 so that it is inserted into the female connector 5. The end of the plug protective housing 2 away from the probe protective housing 1 is inserted into the measuring rod of the radiation dose rate meter. The male connector 6 is electrically connected to the first wire and the second wire in the measuring rod. When the plug protective housing 2 and the probe protective housing 1 are threaded together, when the plug protective housing 2 rotates relative to the male connector 6, the male connector only moves forward, bringing the male connector 6 and the female connector 5 closer together, without causing the male connector 6 to rotate.

[0029] To further optimize the design, a retaining ring 8 connected by threads is provided on the inner wall of the second housing 12. The female connector 5 is installed inside the retaining ring 8. That is, the outer surface of the retaining ring 8 is set as the first external thread, and the inner wall of the second housing 12 is set as the first internal thread. The first external thread is installed on the first external thread, which can limit the position of the retaining ring 8. Since the external force applied manually when inserting or removing the male connector 6 is not along the axis of the male connector 6, but has a certain component perpendicular to the axis, the female connector 5 will bear a certain bending moment. If the bending moment is transmitted to the circuit board 4 and the Geiger-Müller counter tube 3 through the female connector 5, it may cause damage to the circuit board 4 or the Geiger-Müller counter tube 3. By setting the retaining ring 8 between the female connector 5 and the inner wall of the probe protective housing 1, the female connector 5 can transmit the force to the retaining ring 8, so that the bending moment of the female connector is borne by the retaining ring 8 and is not transmitted to the circuit board 4 or the Geiger-Müller counter tube 3, thereby protecting the internal components.

[0030] To further optimize the design, in order to facilitate the installation of the fixing ring 8 inside the second housing 12, several operating holes 81 are provided on the end face of the fixing ring 8. People can insert tools into the operating holes 81 and install the fixing ring 8 inside the second housing 12 by rotating the tools.

[0031] To further optimize the design, in order to facilitate the connection between the plug protective housing 2 and the measuring rod of the radiation dose rate meter, the plug protective housing 2 includes a detachably connected first connecting part 21 and a second connecting part 22. The male connector 6 is installed in the first connecting part 21. The diameter of the second connecting part 22 is smaller than that of the first connecting part 21. The first wire 7 passes through the second connecting part 22 and connects to the measuring rod of the radiation dose rate meter. That is, a wire hole 23 is designed between the first connecting part 21 and the second connecting part 22 for the first wire to pass through. The first wire transitions from the cavity of the first connecting part 21 to the cavity of the second connecting part through the wire hole 23, which facilitates electrical connection with the radiation dose rate meter.

[0032] To further optimize the design, in order to facilitate easy rotation between the male connector 6 and the first connecting part 21, a bearing 9 is provided between the male connector 6 and the first connecting part 21. That is, the male connector 6 is installed in the inner ring of the bearing 9, and the outer ring of the bearing 9 is installed in the cavity of the first connecting part 21. In this way, when the first connecting part 21 rotates, the male connector 6 will not rotate.

[0033] In a further optimized design, the first connecting part 21 and the probe protective housing 1 are connected by a thread or a plug. When the first connecting part 21 and the probe protective housing 1 are connected by a thread, a tight connection between the two can be ensured. When the first connecting part 21 and the probe protective housing 1 are plugged, a locking member 10 connected by a thread is provided on the outside of the first connecting part 21 and the probe protective housing 1. During assembly, the locking member 10 is installed on the outside of the probe protective housing 1 or the outside of the first connecting part 21, so that the first connecting part 21 and the probe protective housing 1 are locked together, ensuring the stability of the connection between the two.
