Description

TECHNICAL FIELD

[0001] The utility model relates to radiation detection technical field, concretely is a kind of radiation dosimeter. BACKGROUND

[0002] Radiation dosimeter can convert radiation energy into quantifiable electric signal, is used for monitoring environmental radiation level, helps to prevent radiation accident, guarantees personnel safety and health.

[0003] Existing radiation dosimeter is mostly handheld and bulky, and the user may need to carry other operating equipment or tools when using the radiation dosimeter, and long-time handheld radiation dosimeter can cause fatigue. Secondly, when needing to operate other equipment with both hands, handheld radiation dosimeter can not be simultaneously considered, affecting work efficiency.

[0004] Therefore, how to make the radiation dosimeter convenient to carry when the operator performs multiple tasks is a problem to be solved. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a kind of radiation dosimeter, by setting clasp on shell, to clamp external product, free both hands of operator, so that operator can consider radiation measurement and other work.

[0006] The utility model mainly realizes the purpose by the following technical solutions:

[0007] A kind of radiation dosimeter, including shell, the shell is formed by the combination of upper shell and lower shell;

[0008] The circuit board is installed in the shell, and the two sides of the circuit board are respectively spaced apart from the upper shell and the lower shell to form two electric device mounting cavities;

[0009] The outer side of the shell is provided with clasp.

[0010] Radiation dosimeter in prior art is bulky and mostly handheld, when operator needs to perform other work simultaneously, if needing to operate other equipment with both hands, handheld radiation dosimeter can not be simultaneously considered, affecting work efficiency. In addition, long-time carrying handheld radiation dosimeter is prone to fatigue, and in narrow or complex environment, handheld instrument can be difficult to keep stable, thereby affecting the accuracy of monitoring result.

[0011] This application addresses the inconvenience of operating handheld radiation dosimeters in the prior art by incorporating a clip on the housing, creating a clipping space between the clip and the housing. This space is used to clip external products, such as other instruments that need to be operated simultaneously, or the wrist, pocket, or other suitable location for clipping. Clipping the radiation dosimeter described in this application to an external product makes operation more convenient than handheld use, freeing the operator's hands and allowing them to perform radiation measurements and other tasks simultaneously, thus improving work efficiency and quality and reducing the time spent in radiation-affected areas.

[0012] A circuit board is installed within the mounting cavity inside the housing to provide a stable mounting and support platform for other electrical components, ensuring that these components do not move or get damaged during installation and use. Simultaneously, the circuit board forms a connection with each electrical component and can process or transmit signals emitted by those components.

[0013] The device is equipped with clips that allow it to be held in place on the operator's work hat, work clothes, or other instruments, eliminating the need for handheld use and allowing the operator to perform other tasks simultaneously.

[0014] While setting the clips, the various electronic components are rationally distributed, reducing the overall size of this utility model. The interior of the housing is divided into two parts by a circuit board, and the electrical accessories paired with the circuit board are respectively installed in the mounting cavities on both sides of the circuit board. Compared with all electrical accessories being located on one side of the circuit, this solution can better utilize the space between the electrical accessories and the circuit board, reducing the overall size. This makes the structure compact, easy to clip, and easy to carry.

[0015] Furthermore, the clip extends along the length of the housing, with one end of the clip fixed to the housing near the top and the other end of the clip close to the housing and near the bottom of the housing.

[0016] The length of the clip is the same as the length of the housing, and the two ends of the clip are close to the two ends of the housing. This ensures the clip has sufficient length to better hold the object, preventing the radiation dosimeter from easily slipping off. Because the clip is fixed to the housing near the top, the tighter the grip under gravity, the less likely the radiation dosimeter will slip off.

[0017] Furthermore,

[0018] The two mounting cavities for the electrical components are respectively the first mounting cavity and the second mounting cavity;

[0019] It also includes a radiation detection module and a battery, which are independently installed in the first mounting cavity and the second mounting cavity, respectively, and are both electrically connected to the circuit board.

[0020] Radiation detection modules convert radiation energy into visible signals, thereby monitoring radiation levels in the environment, ensuring environmental safety, and protecting the health of personnel working in that environment.

[0021] To further improve the portability of this instrument and facilitate repeated use, this solution is battery powered and the radiation detection module and battery are placed in different mounting cavities, connected and communicated via a circuit board.

[0022] The radiation detection module and the battery are separately housed in two separate electrical component mounting cavities, maximizing the use of space within the housing and reducing wasted internal space. This results in a more compact overall structure and a smaller device size. Furthermore, the housing is equipped with heat dissipation holes corresponding to the battery's location.

[0023] To prevent the battery inside the casing from overheating, heat dissipation holes are provided on the casing at the location corresponding to the battery to dissipate heat and ensure the safety of the device during operation.

[0024] Furthermore, a display screen is also provided on the outside of the housing, and the display screen is electrically connected to the circuit board;

[0025] The display screen and the clip are located on opposite sides of the housing.

[0026] A display screen is installed on the upper casing to visually show the radiation dose, making it easy for staff to monitor the radiation level in their environment.

[0027] After the clip is fastened to the external product, the display screen on the upper housing is located on the outside, making it convenient for operators to observe.

[0028] Furthermore, the outer side of the housing is also provided with a X-ray machine switch cap, which is electrically connected to the circuit board.

[0029] A switch cap for the X-ray machine is installed on the outside of the housing. When the radiation level displayed on the screen exceeds the normal range, the switch cap can be opened to send a wireless signal from the circuit board to shut down the X-ray machine, thereby ensuring the user's safety.

[0030] Furthermore, an alarm is provided on the outside of the housing, and the alarm is electrically connected to the circuit board.

[0031] Because operators may overlook changes in radiation levels on the display screen, this solution includes an alarm on the upper casing to provide voice and light alerts, ensuring users are not in a dangerous environment.

[0032] Furthermore, a switch is provided on the outside of the housing, and the switch is electrically connected to the circuit board.

[0033] A switch is installed on the surface of the housing to control the start and stop of this device.

[0034] In summary, this utility model has the following advantages compared with the prior art:

[0035] 1. The present invention provides a clip on the housing, which changes the radiation dosimeter described in this application from a handheld type to a clip type, allowing the operator to perform radiation measurement and other tasks at the same time, thereby speeding up work efficiency and quality and reducing the time spent in the radiation zone; the installation cavity is divided into upper and lower parts by using a circuit board, and the electronic components are distributed on the upper and lower sides of the circuit board respectively, making better use of the vertical space, reducing the overall volume, and further increasing the portability of the present invention.

[0036] 2. Install the X-ray machine switch cap. When the radiation level displayed on the screen exceeds the normal range, the operator can immediately use the wireless signal of the X-ray machine switch cap to turn off the radiation machine, thereby ensuring the health of the user.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0043] Example:

[0044] like Figs. 1-3 As shown,

[0045] A radiation dosimeter includes a housing 3, which is assembled from an upper housing 301 and a lower housing 302;

[0046] A circuit board 5 is installed inside the housing 3. The two sides of the circuit board 5 are respectively spaced apart from the upper housing 301 and the lower housing 302 to form two electrical component mounting cavities.

[0047] The outer side of the housing 3 is provided with a clip 6.

[0048] Existing radiation dosimeters are large and mostly handheld. When operators need to perform other tasks at the same time, they may not be able to operate other equipment with both hands at the same time, which affects work efficiency. In addition, carrying a handheld radiation dosimeter for a long time can easily lead to fatigue. In confined or complex environments, handheld instruments may be difficult to keep stable, thus affecting the accuracy of monitoring results.

[0049] This application addresses the inconvenience of operating handheld radiation dosimeters in the prior art by incorporating a clip 6 on the housing 3. This clip 6 creates a space between the clip 6 and the housing 3, allowing for the clipping of external products, such as other instruments requiring simultaneous operation, or the wrist, pocket, or other suitable location for clipping. Clipping the radiation dosimeter 6 onto an external product, compared to handheld operation, is more convenient, freeing the operator's hands and enabling them to perform radiation measurements and other tasks simultaneously, thus improving work efficiency and quality and reducing the time spent in radiation-affected areas.

[0050] A circuit board 5 is installed inside the mounting cavity of the housing 3 to provide a stable mounting and support platform for other electrical components, ensuring that these components do not move or get damaged during installation and use. Simultaneously, the circuit board 5 can form a connected circuit with each electrical component and can be used to process or transmit signals emitted by each component.

[0051] The device is equipped with a clip 6, which allows it to be clamped onto the operator's work hat, work clothes, or other instruments, eliminating the need for hand-holding and facilitating the operator to perform other tasks simultaneously.

[0052] While setting the clip 6, the various electronic components are rationally distributed, reducing the overall size of this utility model. The interior of the housing 3 is divided into two parts by the circuit board 5, and the electrical accessories paired with the circuit board 5 are respectively installed in the mounting cavities on both sides of the circuit board 5. Compared with all electrical accessories being set on one side of the circuit, this solution can make better use of the space between the electrical accessories and the circuit board, reducing the overall size, making the structure of this solution compact, easy to clip, and easy to carry.

[0053] As one possible implementation of the above scheme, the housing 3 is a cuboid, and the housing 3 is divided into two parts, an upper housing 301 and a lower housing 302, from the middle of the side of the housing 3. The circuit board 5 is fixed on the lower housing 302 and close to the connection between the lower housing 302 and the upper housing 301.

[0054] 2 Furthermore, the clip 6 extends along the length of the housing 1, one end of the clip 6 is fixed to the housing 3 near the top, and the other end of the clip 6 is close to the housing 3 and near the bottom of the housing 3.

[0055] The length direction of the clip 6 is the same as that of the housing 3, and the two ends of the clip 6 are close to the two ends of the housing 3, so the clip has sufficient length to better hold the object and prevent the radiation dosimeter from easily falling off the object clipped to the clip 6. Because the fixed part of the clip 6 to the housing 3 is close to the top of the housing 3, the tighter the clamping under the action of gravity, the less likely the radiation dosimeter will slip off.

[0056] Furthermore, the two electrical component mounting cavities are respectively a first mounting cavity and a second mounting cavity;

[0057] It also includes a radiation detection module 2 and a battery 4, which are independently installed in the first mounting cavity and the second mounting cavity, respectively, and are both electrically connected to the circuit board.

[0058] Radiation detection module 2 converts radiation energy into a visible signal, thereby monitoring the radiation level in the environment, ensuring environmental safety, and protecting the health of personnel in the environment.

[0059] Specifically, in practical applications, the radiation detection module 2 can utilize existing gas detectors, using gas as the detection medium. When radiation particles enter the detector, ionization or excitation occurs in the gas, generating a measurable signal. Alternatively, it can utilize changes in the conductivity of existing semiconductor materials to detect radiation. Furthermore, it can utilize existing scintillators to convert radiation energy into optical signals, which are then converted into electrical signals via photomultiplier tubes (PMTs) or photodiodes (APDs).

[0060] To further improve the portability of this instrument and facilitate repeated use of this solution, this solution uses battery 4 for power supply and places the radiation detection module 2 and battery 4 in different mounting cavities, which are connected and communicated through circuit board 5.

[0061] By placing the radiation detection module 2 and the battery 4 separately in two electrical component mounting cavities, more space can be utilized within the housing 3, thereby reducing wasted space and making the overall structure more compact, thus reducing the size of the device.

[0062] Furthermore, the housing 3 is provided with heat dissipation holes 10 at the position corresponding to the battery 4.

[0063] To prevent the battery 4 inside the casing 3 from overheating, a heat dissipation hole 10 is provided on the casing 3 at the position corresponding to the battery 4 for heat dissipation and to ensure the safety of the device operation.

[0064] Furthermore, a display screen 1 is also provided on the outside of the housing 3, and the display screen 1 is electrically connected to the circuit board 5;

[0065] The display screen 1 and the clip 6 are located on opposite sides of the housing 3.

[0066] A display screen 1 is installed on the upper housing 301 to visually display the radiation dose, making it convenient for staff to visually monitor the radiation level in the environment.

[0067] After the clip 6 is fastened to the external product, the display screen 1 on the upper housing 301 is located on the outside, making it convenient for operators to observe.

[0068] Specifically, the display screen 1 adopts an organic light-emitting diode display screen, which has high brightness, high contrast and fast response.

[0069] Specifically, the display screen 1 can also be an LCD display screen with relatively low cost and power consumption, or a high-brightness LED display screen suitable for outdoor display, which are already available in the technology.

[0070] Furthermore, the outer side of the housing 3 is also provided with a X-ray machine switch cap 7, which is electrically connected to the circuit board 5.

[0071] A X-ray machine switch cap 7 is installed on the outside of the housing 3. When the radiation level displayed on the display screen 1 is observed to be outside the normal range, the X-ray machine switch cap 7 can be turned on, so that the circuit board 5 can send a wireless signal to shut down the X-ray machine that emits radiation, thereby ensuring the personal safety of the user.

[0072] As one possible implementation of the above solution, the X-ray machine switch cap 7 is located on the side of the housing 3, making it easier for the user to access and operate.

[0073] Furthermore, an alarm 9 is provided on the outside of the housing 3, and the alarm 9 is electrically connected to the circuit board 5.

[0074] Since operators may overlook changes in radiation levels on display screen 1 during work, this solution includes an alarm 9 on the upper housing 301 to provide voice and light alerts and ensure that users are not in a dangerous environment.

[0075] As one possible implementation of the above solution, the alarm 9 is located on the side of the housing opposite to the clip 6, and will not be obstructed by the clip 6 or the clipped object, ensuring that the user can see the warning immediately.

[0076] As one possible implementation of the above solution, the alarm 9 is a light guide column in the prior art that transmits light emitted from inside the product to indicate the radiation level and to warn of excessive radiation.

[0077] As one possible implementation of the above solution, the alarm 9 is a voice device or similar device in the prior art, which issues a voice reminder so that the user can turn off the radiation source and leave the environment with excessive radiation in a timely manner.

[0078] Furthermore, a switch 8 is provided on the outside of the housing 3, and the switch 8 is electrically connected to the circuit board 5.

[0079] A switch 8 is provided on the surface of the housing 3 to control the start and stop of the device.

[0080] In practical use, the clip 6 of the device is fastened to the worker's upper pocket. Before entering the work area, switch 8 is turned on. After entering the work area, the radiation detection module 2 receives the radiation signal and converts it into a visible electrical signal, which is then transmitted to the display screen 1 via circuit board 5 to display the specific radiation dose. When the radiation dose in the work area exceeds the standard, circuit board 5 triggers alarm 9, reminding the worker to operate the X-ray machine switch cap 8. This causes the wireless signal transmitting structure on circuit board 5 to emit a wireless signal, remotely shutting down the emitting X-ray machine, thus ensuring the worker's safety. After work is completed, the device is removed and switch 8 is turned off.

[0081] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
