Description

Technical Field

[0001] The utility model relates to the technical field of radiation detection, in particular to a portable radiation detection device. Background Art

[0002] Radiation refers to the phenomenon that energy diffuses outward in the form of electromagnetic waves or particles. Radiation can be divided into two categories: non-ionizing radiation and ionizing radiation. Non-ionizing radiation includes visible light, radio waves, microwaves, etc. These radiations have low energy and usually do not change the atomic structure of matter. Ionizing radiation, such as X-rays, gamma rays, and alpha and beta particles released by radioactive substances, has high energy and can ionize the atoms of matter, that is, remove electrons and change the structure of atoms. High doses of ionizing radiation may cause cell damage or even cancer.

[0018] See also Figure 1-3 The utility model provides a technical solution: a portable radiation detection device, comprising a detector body 1, a protective shell 2 and a cover plate 3, the detector body 1 and the protective shell 2 are both arranged in a square structure, and the interior of the protective shell 2 is hollow, and the detector body 1 is arranged in cooperation with the protective shell 2; the upper part of the protective shell 2 is arranged open, the cover plate 3 is arranged above the detector body 1, and the cover plate 3 is arranged in cooperation with the open part of the protective shell 2; a display screen 11 is arranged on one side of the detector body 1, and an operation button 12 is arranged on the detector body 1 below the display screen 11; toothed belts 21 are arranged on the inner walls on both sides of the protective shell 2, and gears 13 are arranged at the bottom ends of both sides of the detector body 1, and the gears 13 and the toothed belts 21 are meshed with each other.

[0019] Furthermore, an annular clamping strip 31 is provided on the lower side of the cover plate 3, and the clamping strip 31 is clamped on the outer side of the upper edge of the protective shell 2; a sealing strip 32 is provided on the inner side of the clamping strip 31, and the sealing strip 32 is in contact with the upper edge of the protective shell 2, and the sealing strip 32 is made of rubber material.

[0020] Furthermore, a pull rod 33 is provided at the lower part of the cover plate 3 , and a sleeve 14 is provided at the upper part of the detector body 1 . The pull rod 33 is docked in the sleeve 14 and connected to a spring in the sleeve 14 .

[0021] Furthermore, a fixing belt 24 is provided on the side of the protective shell 2 facing away from the display screen 11, and the fixing belt 24 is made of nylon cloth; a T-shaped limiting slide 22 is provided on the inner wall of the protective shell 2 away from the display screen 11, and a limiting slide groove is correspondingly provided on the detector body 1, and the limiting slide groove is engaged with and stuck on the outside of the limiting slide 22 and slides along the limiting slide 22.

[0022] Furthermore, a detection element and a controller are provided inside the detector body 1, and switch buttons 23 are provided on the outside of both sides of the protective shell 2; the gear 13 is driven by a servo motor embedded in the bottom of the detector body 1, and the servo motor, detection element, display screen 11, operation button 12, and switch button 23 are all electrically connected to the controller.

[0023] Working principle: In actual use, the user holds the protective shell 2, and the fixing belt 24 on the back of the protective shell 2 can be clamped on the outside of the palm, so that the user can hold the protective shell 2 more stably. By pressing the switch button 23, a signal can be sent to the controller to turn on the servo motor of the gear 13, and the gear 13 rotates to engage with the toothed belt 21; the gears 13 on both sides work synchronously, thereby driving the detector body 1 to move up and down, and move out of the protective shell 2 for use, or retract it into the protective shell 2.
