Description

Technical Field

[0001] The utility model relates to the technical field of measuring instrument equipment, in particular to a neutron dose rate measuring instrument with a protection structure. Background Art

[0002] A neutron dose rate meter is a device used to measure the neutron radiation dose rate. Neutrons are uncharged particles that pose a radiation hazard to many materials and biological tissues. Therefore, monitoring and measuring neutron radiation is essential for radiation protection and safety. Neutron dose rate meters usually use the effects of the interaction between neutrons and nuclear material in the detector to measure the neutron radiation dose rate. These detectors can be solid-state nuclear material-based detectors or liquid or gas scintillator detectors. The measuring instrument converts the detected neutron radiation into an electrical signal, which is amplified, processed and converted through an internal electronics system to ultimately display the neutron radiation dose rate. These instruments usually have high sensitivity and accuracy and can be used to monitor neutron radiation levels in nuclear power plants, nuclear industry, medical radiation therapy and other fields to ensure the safety of workers and the public.

[0003] The existing neutron dose rate meters currently have certain limitations in terms of protection. Usually, these instruments are only protected by a simple metal shell. When the device is subjected to external forces, whether from accidental collisions, vibrations or other forms of impact, these forces will be transmitted to the delicate parts inside the instrument, which may cause damage to the internal parts. In this case, the sensitive parts and precision machinery inside the device are easily affected by external impacts, thereby causing equipment failure or damage. Since neutron dose rate meters usually need to maintain a high degree of accuracy and stability, any form of damage may affect its normal working performance and may even cause inaccurate data or equipment failure. In addition, since neutron radiation itself has certain penetration and energy, if the external protection of the measuring instrument is not sufficient to resist the influence of radiation, the delicate parts inside the device may also be damaged by neutron radiation, further exacerbating the vulnerability and failure risk of the device. Therefore, for key equipment such as neutron dose rate meters, how to improve their impact resistance and protection to ensure that the delicate parts inside the device are not affected by external forces is an urgent problem to be solved.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2 , the utility model provides an embodiment: a neutron dose rate measuring instrument with a protective structure, comprising a protective shell 1, a measuring hub 2 is arranged inside the protective shell 1, a top block 5 is slidably connected inside the protective shell 1, a fixed sleeve 7 is slidably connected to the bottom of the top block 5, a fixed frame 6 is fixedly connected to the bottom of the fixed sleeve 7, the fixed frame 6 is fixedly connected to the outer wall of the measuring hub 2, a fixed column 9 is slidably connected inside the fixed frame 6, a spring 10 is sleeved on the outer wall of the fixed column 9, a push-pull block 8 is fixedly connected to one end of the spring 10, a connecting rod 11 is arranged at the bottom of the fixed column 9, a plurality of connecting rods 11 are symmetrically distributed on the left and right, one side of the connecting rod 11 is rotatably connected to the bottom of the fixed column 9, and the other side of the connecting rod 11 is rotatably connected to the inside of the fixed frame 6, a slider 12 is rotatably connected between the connecting rods 11, a shock absorbing assembly is arranged inside the fixed frame 6, the shock absorbing assembly includes a damper 2 13 and a push-pull block 2 14, the damper 2 13 is arranged inside the slider 12, and the output end of the damper 2 13 is fixedly connected to one side of the push-pull block 2 14;

[0031] Specifically, when external force acts on the neutron dose rate meter, its internal structural design plays a vital role. By applying force to the protective shell 1, a series of complex and precise mechanical reactions are triggered. First, the top block 5 produces a small displacement, causing the top block 5 to apply a squeezing force to the push-pull block 8 on both sides. This process triggers a chain reaction, pushing the spring 10 to be stressed. The spring 10 uses the elastic potential energy generated by its own reduction to partially offset the external impact force and play a buffering role; at the same time, the fixed column 9 also starts to rotate with the movement of the push-pull block 8, causing the inclination angle between the connecting rods 11 to change synchronously. This chain reaction further pushes the slider 12 to apply a squeezing force to the push-pull block 14 on both sides. Finally, the damper 13 effectively buffers the external impact force through the displacement of the push-pull block 14, achieving a shock-absorbing effect; the subtlety of this design structure lies in its ability to convert external impact force into internal mechanical movement, and through the synergistic effect of multiple components, gradually slow down and disperse the impact of the impact force, protecting the precision parts inside the neutron dose rate meter from damage.

[0032] Reference Figure 1-Figure 3 , a push-pull block 18 is slidably connected inside the fixed frame 6, the other end of the spring 10 is fixedly connected inside the fixed frame 6, the top of the slider 12 fits with the bottom of the push-pull block 2 14, one side of the push-pull block 18 fits with one side of the top block 5, a sealing ring 2 17 is provided between the protective shell 1 and the measuring hub 2, a mounting buckle 18 is provided inside the sealing ring 2 17, a display screen 3 is provided on one side of the measuring hub 2, a button 4 is provided on one side of the measuring hub 2, a handle 15 is fixedly connected to the outer wall of the protective shell 1, the sealing ring 2 17 is connected to the protective shell 1 through the mounting buckle 18, a sealing ring 16 is fixedly connected to the outer wall of the measuring hub 2, and the sealing ring 16 fits with the sealing ring 2 17;

[0033] Specifically, through the mounting buckle 18, the sealing ring 2 17 can be firmly installed between the protective shell 1 and the measuring hub 2. At the same time, with the sealing ring 16 glued to the measuring hub 2 itself, a perfect combination between the sealing ring 16 and the sealing ring 2 17 is achieved. This design enables the gap at the joint between the protective shell 1 and the measuring hub 2 to be effectively sealed to prevent the intrusion of external environmental factors and ensure the safe operation of the internal components of the measuring instrument. Through the handle 15, we can carry this precision instrument easily and conveniently, which provides great convenience for portability in practical applications.

[0034] Working principle: When the device is subjected to external force, the protective shell 1 is subjected to force, and the top block 5 will produce a slight displacement at this time, so that the corresponding top block 5 squeezes the push-pull block 8 on both sides, so that it squeezes the spring 10, and the elastic potential energy generated by the spring 10 through its own reduction offsets part of the impact force. At the same time, the fixed column 9 will also start to move eastward due to the movement of the push-pull block 8, so that the inclination angle between the connecting rods 11 changes synchronously, and then push the slider 12 to squeeze the push-pull block 2 14 on both sides, so that the damper 2 13 buffers the impact force through the displacement of the push-pull block 2 14, so as to achieve the shock absorption effect, and the corresponding mounting buckle 18 can firmly install the sealing ring 2 17 at the position between the protective shell 1 and the measuring hub 2, and then cooperate with the sealing ring 16 glued to the measuring hub 2 itself, so that the sealing ring 16 and the sealing ring 2 17 can be sealed through the gap at the joint of the protective shell 1 and the measuring hub 2, and the device can be conveniently carried through the handle 15.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
