Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a nuclear waste barrel scanning monitoring device. Background Art

[0002] Nuclear waste refers to useless materials containing unstable elements that emit alpha, beta, and gamma radiation, accompanied by heat generation. Once released into the environment, nuclear waste can contaminate water, air, and soil, and enter the human body through various pathways. When radioactive radiation exceeds a certain level, it can kill cells, hinder normal cell division and regeneration, and cause genetic mutations within cells. Therefore, nuclear waste often requires specialized storage containers. Nuclear waste drums are used to reduce the volume of solid radioactive waste and solidify liquid radioactive waste from nuclear power plants. Radiation safety testing of the exterior of nuclear waste drums is required, primarily focusing on radiation dose measurements. Because the surface of nuclear waste drums can be highly radioactive, access to untested drums is strictly prohibited.

[0003] Patent number CN202121078662.2 is a radiation safety monitoring device for nuclear waste barrels. Its principle is to use a mechanical claw to grab the nuclear waste barrel onto a turntable, and then the motor drives the turntable to rotate, so that the nuclear waste barrel also rotates. The camera and radiation detection sensor then inspect and photograph the surface of the nuclear waste barrel. If there is any unqualified, the sensor will inform the staff.

[0004] However, existing cameras and radiation detection sensors can only detect the top of nuclear waste barrels, but cannot detect the sides and surrounding areas of nuclear waste barrels, resulting in incomplete detection and unsatisfactory results. To address the above problem, a device has been designed that can detect the sides around nuclear waste barrels. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the present invention provides a nuclear waste barrel scanning and monitoring device with the following beneficial effects:

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] A nuclear waste barrel scanning and monitoring device comprises: a conveyor belt 11, with a nuclear waste barrel 12 mounted on top of the conveyor belt 11; a rotating device 2 mounted on top of the nuclear waste barrel 12, the rotating device 2 comprising: a horizontal plate 21 mounted above the nuclear waste barrel 12; a motor 22 mounted on top of the horizontal plate 21, with its output shaft extending through the horizontal plate 21; a horizontal bar 23 mounted at the bottom of the output shaft of the motor 22; a vertical bar 24 mounted at the bottom of one end of the horizontal bar 23; and three detection devices 25, each extending through the outer wall of the vertical bar 24. The motor 22 is a reduction motor, operating at 0.5 revolutions per minute.

[0029] See Figure 1-2During use, the nuclear waste barrel 12 is transported to the bottom of the horizontal plate 21 by the conveyor belt 11, and the horizontal rod 23 is driven by the motor 22 to rotate, so that the vertical rod 24 also rotates. The detection device 25 on the vertical rod 24 can detect the outer wall of the nuclear waste barrel 12 all around. The motor 22 uses a reduction motor with a speed of 0.5 revolutions per minute, which can make the detection device 25 more accurate during the detection process and avoid omissions.

[0030] Example 2

[0031] The mobile function is added based on the first embodiment;

[0032] A nuclear waste barrel scanning and monitoring device comprises: a conveyor belt 11, with a nuclear waste barrel 12 disposed on top of the conveyor belt 11; a rotating device 2 disposed on top of the nuclear waste barrel 12, the rotating device 2 comprising: a horizontal plate 21 disposed above the nuclear waste barrel 12; a motor 22 disposed on top of the horizontal plate 21, with its output shaft extending through the horizontal plate 21; a horizontal bar 23 disposed at the bottom of the output shaft of the motor 22; a vertical bar 24 disposed at the bottom of one end of the horizontal bar 23; and three detection devices 25, each extending through the outer wall of the vertical bar 24. The motor 22 is a reduction motor with a speed of 0.5 revolutions per minute. A moving device 3 is disposed within the horizontal bar 23, comprising: a slide 31 disposed within the horizontal bar 23; a slider 32 slidably disposed within the slide 31; and a slide bar 33 disposed at the bottom of the slider 32, with the top of the vertical bar 24 connected to the slide bar 33. The moving device 3 also includes a rack 34 disposed at the bottom of the crossbar 23; a second motor 35 disposed at the bottom of the slide bar 33, with its output shaft extending through the slide bar 33; and a gear 36 disposed at the top of the output shaft of the second motor 35 and meshing with the rack 34. Ball bearings 37 are disposed at the bottom of both sides of the slider 32. A bump 38 is disposed at the top of one end of the slider 32, and a stopper 39 is disposed at the top of the crossbar 23. A proximity switch 1 41 is disposed on one side of the vertical bar 24, and a proximity switch 2 42 is disposed on one side of the vertical bar 24.

[0033] See Figure 1-2When in use, according to the proximity switch 1 41 detecting no signal, the motor 2 35 drives the gear 36 to engage the rack 34 so that the slider 32 slides in the slide groove 31 and the slide bar 33 slides in the direction of the nuclear waste barrel 12, so that the detection device 25 approaches the nuclear waste barrel 12. When the proximity switch 2 42 detects a signal, the motor 2 35 drives the gear 36 to rotate in the opposite direction to engage the rack 34, so that the slide bar 33 moves in the opposite direction of the nuclear waste barrel 12, so that the distance between the detection device 25 and the nuclear waste barrel 12 becomes farther. The proximity switch 1 41 and the proximity switch 2 42 can control the rotation of the motor 2 35 so that the detection device 25 is always at a distance of ten to twelve millimeters from the nuclear waste barrel 12, making the detection more accurate. Nuclear waste barrels 12 of different sizes can be used. The setting of the ball 37 can reduce the friction between the slider 32 and the cross bar 23 and reduce friction loss. The setting of the stop block 39 and the protrusion 38 can prevent the slider 32 from slipping out of the slide groove 31 and causing component separation.
