Description

Technical Field

[0001] This utility model belongs to the technical field of nuclear radiation detectors, specifically, it relates to a portable nuclear radiation detector. Background Technology

[0002] With the widespread application of nuclear technology in energy, medical, and industrial fields, the demand for nuclear radiation monitoring is increasing. Portable nuclear radiation detectors, due to their flexibility and real-time monitoring capabilities, are widely used in nuclear power plant inspections, radiation environment monitoring, emergency response, and personal protection. However, existing portable radiation detectors still have many shortcomings in terms of wearing stability, ease of operation, and battery life management, as detailed below;

[0003] Traditional detectors often use simple straps or buckles for fixation, which are prone to displacement or detachment when the user moves or during operation, affecting the accuracy of the monitoring data. Some designs use rigid buckles for fixation, which can enhance stability, but are inconvenient to disassemble and may cause discomfort after prolonged wear. Some detectors use a hard shell that is directly fixed to the arm, lacking cushioning design, which may compress the skin and affect blood circulation after prolonged wear. On the other hand, relying solely on elastic straps cannot guarantee the stability of the instrument during strenuous exercise.

[0004] To address the aforementioned issues, this application proposes a portable nuclear radiation detector. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a portable nuclear radiation detector to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable nuclear radiation detector includes a liner, bandages on both sides of the liner with Velcro straps, a storage box on the top of the liner, a detector body slidably connected inside the storage box, a gas injection box on the bottom inner wall of the storage box that cooperates with the detector body, and a push-up airbag on the bottom of the liner that communicates with the gas injection box.

[0008] The jacking and fixing mechanism includes two piston plates, which are slidably fitted onto the inner wall of the gas injection box. Two arc-shaped top packs are installed on the top of the gas injection box, and the gas injection box and the two arc-shaped top packs are interconnected. A push rod is slidably connected to the gas injection box, and the push rod is drivenly connected to the two piston plates.

[0009] The charging mechanism includes a battery, which is mounted on one side of a storage box. A connector is slidably connected to the inner wall of one side of the storage box and is connected to the battery.

[0010] Preferably, the push-fixing mechanism further includes four wedge-shaped pads, which are respectively fixedly installed on the side of the two piston plates that are close to each other. Two connecting blocks are fixedly installed on the push rod, and wedge-shaped top blocks are fixedly installed on both sides of the connecting blocks. The wedge-shaped top blocks cooperate with the corresponding wedge-shaped pads. A buckle is fixedly installed on one side of the storage box, and a push handle is fixedly installed on one end of the push rod. The push handle cooperates with the buckle.

[0011] The moving push rod drives two connecting blocks to move, which in turn drives two wedge-shaped top blocks to move. The wedge-shaped top blocks, in cooperation with the wedge-shaped pads, drive the piston plate to move, thereby compressing the gas in the injection box and introducing it into the arc-shaped top package, causing the arc-shaped top package to expand.

[0012] Preferably, two positioning rods are fixedly installed on the inner wall of the gas injection box. The two positioning rods are slidably connected to the two piston plates, and two return springs are sleeved on the positioning rods. The two return springs are located on the side of the two piston plates that are far apart from each other.

[0013] The positioning rod is slidably connected to the two piston plates, and the return spring is located on the side of the two piston plates that are far apart from each other, so that the positioning rod can limit the piston plates and automatically reset under the action of the return spring.

[0014] Preferably, the bottom of the detector body has two notches that cooperate with the corresponding arc-shaped top cover, and two rubber pads are installed on the top inner wall of the storage box, which cooperate with the detector body.

[0015] The notch on the main body of the detector allows the arc-shaped top pack to be pushed into the notch during expansion, thus securing the main body of the detector.

[0016] Preferably, the charging mechanism further includes a concave plate, which is fixedly installed on one side of the detector body. A metal spring is installed on the inner top of the concave plate, and two electrical contacts are installed on the top of the connector, which cooperate with the metal spring.

[0017] The concave clamping plate allows for the mounting of the connector, and the interaction between the connector head and the metal spring ensures stable charging of the detector body.

[0018] Preferably, a wedge plate is fixedly installed at the bottom of the connector, and the wedge plate cooperates with the push rod.

[0019] By setting the wedge plate, when the push rod moves, it can push the connector to move, thereby driving the connector to push and charge the detector body.

[0020] In summary, the technical effects and advantages of this utility model are as follows:

[0021] By using the gas injection box and the curved top pack together, the gas pressure causes the flexible top pack to expand precisely and embed into the recess at the bottom of the detector, forming a three-dimensional curved surface engagement. The rubber pad provides cushioning friction, achieving a combination of rigidity and flexibility for shockproof fixation, which is more adaptable to different dimensional tolerances than traditional spring clips.

[0022] By connecting the push-up airbag to the air injection box to form a closed-loop air pressure system, pressure is automatically delivered to the bandage when the device is secured, enabling real-time adaptive adjustment of the tightness. After the Velcro is initially secured, the pneumatic system can make secondary fine adjustments to the pressure distribution, avoiding the localized pressure problems of traditional purely mechanical straps.

[0023] A wedge-shaped plate integrated at the end of the push rod pushes the connector to slide during the final stroke of the fixing action, allowing the contact head to make progressive contact with the metal spring. The concave guide structure of the retaining plate ensures that the charging interface remains aligned during movement, avoiding wear from repeated plugging and unplugging.

[0034] Reference Figure 1 and Figure 4The push-fixing mechanism 5 also includes four wedge-shaped pads 55, which are respectively fixedly installed on the side of the two piston plates 51 that are close to each other. Two connecting blocks 53 are fixedly installed on the push rod 52. Wedge-shaped top blocks 54 are fixedly installed on both sides of the connecting blocks 53. The wedge-shaped top blocks 54 cooperate with the corresponding wedge-shaped pads 55. A buckle 59 is fixedly installed on one side of the storage box 2. A push handle 58 is fixedly installed on one end of the push rod 52. The push handle 58 cooperates with the buckle 59. Two positioning rods 56 are fixedly installed on the inner wall of the air injection box 4. The two positioning rods 56 are slidably connected to the two piston plates 51. Two return springs 57 are sleeved on the positioning rods 56. The two return springs 57 are located on the side of the two piston plates 51 that are far from each other. The bottom of the detector body 3 is equipped with two notches 512. The notches 512 cooperate with the corresponding arc-shaped top package 510. The top of the storage box 2 is also fixedly installed. Two rubber pads 511 are installed on the inner wall. The rubber pads 511 cooperate with the detector body 3. The moving push rod 52 drives the two connecting blocks 53 to move. The connecting blocks 53 drive the two wedge-shaped top blocks 54 to move. The wedge-shaped top blocks 54 cooperate with the wedge-shaped pads 55 to drive the piston plate 51 to move, thereby compressing the gas in the gas injection box 4 and introducing it into the arc-shaped top package 510, thereby causing the arc-shaped top package 510 to expand. Through the setting of the notch 512 on the detector body 3, the arc-shaped top package 510 can be pushed into the notch 512 when it expands, thereby fixing the detector body 3. The positioning rod 56 is slidably connected with the two piston plates 51, and the return spring 57 is located on the side of the two piston plates 51 that are far away from each other, so that the positioning rod 56 can limit the piston plate 51 and automatically reset under the action of the return spring 57.

The moving push rod 52 moves the two connecting blocks 53, which in turn move the two wedge-shaped top blocks 54. The wedge-shaped top blocks 54, in cooperation with the wedge-shaped pads 55, move the piston plate 51, thereby compressing the gas in the gas injection box 4 and introducing it into the arc-shaped top pack 510. This causes the arc-shaped top pack 510 to expand. The notch 512 on the detector body 3 allows the arc-shaped top pack 510 to push into the notch 512 during expansion, thus securing the detector body 3 in place. Gas is injected into the push airbag 9, and the inflated push airbag 9 tightens the bandage 7, thereby stably fixing the detector body 3 to the arm. The positioning rod 56 is slidably connected to the two piston plates 51, and the return spring 57 is located on the side of the two piston plates 51 that are far apart from each other, so that the positioning rod 56 can limit the piston plate 51 and automatically reset under the action of the return spring 57.
