Description

Technical Field

[0001] This utility model relates to the field of radiation energy technology, specifically to a radiation energy detection device. Background Technology

[0002] Radioactive energy refers to the energy emitted by radioactive materials in the form of waves or particles.

[0003] In the prior art, Chinese invention with publication number CN115040152A discloses a radiation protection performance testing device for radiological diagnostic and treatment equipment. The radiation protection performance testing device realizes the function of automatically adjusting the distance and height, and is suitable for testing equipment of different specifications, thereby improving the applicability of the device and providing high flexibility.

[0004] However, when the object to be tested is poured onto the carrier plate, its shape will be an upward convex arc. Since the detector can only move in a straight line, when testing the object on the carrier plate, the detection head will be at a certain angle to the surface of the object, making the distance between the detection head and each part of the surface of the object different, thus causing detection errors. Utility Model Content

[0005] The purpose of this invention is to provide a radiation detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a radiation detection device, the radiation detection device comprising:

[0007] A workbench, with a second motor fixed at its lower end, a bearing plate at the output end of the second motor, a rotating rod movably inserted through the side surface of the workbench, and a first belt movably sleeved on the outer surface of the rotating rod;

[0008] A fan-shaped bracket has a belt groove on its inner side surface. A second belt is movably mounted on the inner wall of the belt groove. A radiation detector is fixed on the upper surface of the second belt. A cloud laser rangefinder is mounted on the lower end of the radiation detector.

[0009] Preferably, the worktable has a through groove on its upper surface, the support plate is located at the upper end of the worktable, the rotating rod has two sets, the two sets of rotating rods are symmetrically distributed, and the outer surface of the rotating rod has threads.

[0010] Preferably, a transmission plate is fixed at the lower end of the fan-shaped bracket, and a threaded hole is opened inside the transmission plate. The transmission plate corresponds to the through groove and is movably engaged, and the thread corresponds to the threaded hole and is movably engaged.

[0011] Preferably, the first belt is sleeved on the outer surface of the two sets of rotating rods at their ends, one set of the rotating rods is fixed with a first motor, the inner surface of the fan-shaped bracket is provided with a slide rail, and the lower end surface of the fan-shaped bracket is movably provided with a rotating shaft.

[0012] Preferably, the two ends of the second belt are respectively movably sleeved on the outer surfaces of two sets of rotating shafts, one set of rotating shafts is fixed with a third motor at its end, and the side surface of the radiation detector is fixed with a fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Because the second belt is fixedly connected to the fixed block, the movement of the second belt in the belt groove will drive the radiation detector to move.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a radiation detection device.

[0025] In Example 1, a second motor 8 is fixed at the lower end of the workbench 1. A bearing plate 4 is provided at the output end of the second motor 8. A rotating rod 7 is movably inserted through the side surface of the workbench 1. A first belt 10 is movably sleeved on the outer surface of the rotating rod 7. When the first motor 6 is started, it drives one set of rotating rods 7 to rotate. Since the two sets of rotating rods 7 are connected by the first belt 10, the rotation of one set of rotating rods 7 will drive the other set of rotating rods 7 to rotate. Due to the threaded engagement, the rotation of the rotating rod 7 will drive the fan-shaped bracket 2 to move along its axial direction toward the center of the bearing plate 4.

[0026] A belt groove 16 is provided on the inner side surface of the fan-shaped bracket 2. A second belt 14 is movably provided on the inner wall of the belt groove 16. A radiation detector 3 is fixed on the upper surface of the second belt 14. A cloud laser rangefinder 20 is provided at the lower end of the radiation detector 3. Since the second belt 14 is fixedly connected to the fixed block 18, the second belt 14 will drive the radiation detector 3 to move when it moves in the belt groove 16. Since the trajectory of the belt groove 16 is arc-shaped and the axis of the arc is located at the center of the support plate 4, the movement of the radiation detector 3 and the cloud laser rangefinder 20 will be arc-shaped when the second belt 14 drives the radiation detector 3 to move. The distance between the radiation detector 3 and the cloud laser rangefinder 20 and the center of the support plate 4 will be the same no matter where they move. That is, the distance between the radiation detector 3 and the cloud laser rangefinder 20 and every surface of the object to be measured on the support plate 4 is the same.

[0027] Based on Embodiment 1, in order to ensure that the distance from the detection head to each surface of the object being tested is the same, a through groove 5 is provided on the upper surface of the worktable 1, the support plate 4 is located at the upper end of the worktable 1, and there are two sets of rotating rods 7, which are symmetrically distributed. The outer surface of the rotating rod 7 is provided with threads 9, and the lower end of the sector bracket 2 is fixed with a transmission plate 12. The transmission plate 12 is provided with a threaded hole 13 inside. The transmission plate 12 corresponds to the through groove 5 and is movably engaged. The threads 9 correspond to the threaded hole 13 and are movably engaged. Due to the threaded engagement, when the rotating rod 7 rotates, it will drive the sector bracket 2 to move towards the center of the support plate 4 along its axial direction.

[0028] The first belt 10 is fitted at both ends onto the outer surfaces of the two sets of rotating rods 7 near their ends. The first motor 6 is fixed to the end of one set of rotating rods 7. A slide rail 17 is provided on the inner surface of the fan-shaped bracket 2. The track of the slide rail 17 is arc-shaped and coaxial with the belt groove 16. Therefore, when the second belt 14 drives the radiation detector 3 to move, the roller 19 will not interfere. A rotating shaft 15 is movably provided on the lower side surface of the fan-shaped bracket 2. The two ends of the second belt 14 are movably fitted onto the outer surfaces of the two sets of rotating shafts 15. A third motor 11 is fixed to the end of one set of rotating shafts 15. A fixing block 18 is fixed to the side surface of the radiation detector 3.

[0029] The fixing block 18 is fixed to the uppermost surface of the second belt 14. The fixing block 18 is movably locked in the inner wall of the belt groove 16. The side surface of the radiation detector 3 is movably provided with a roller 19. The roller 19 corresponds to the slide rail 17 and is movably locked. The width of the slide rail 17 is greater than the diameter of the roller 19, so the roller 19 can roll inside the slide rail 17 without being interfered with.

[0030] In actual use, the object to be tested is first poured onto the support plate 4. Due to the influence of gravity, the object to be tested forms an upward convex slope on the support plate 4. Then, the first motor 6 is started to drive one set of rotating rods 7 to rotate. Since the two sets of rotating rods 7 are connected by the first belt 10, the rotation of one set of rotating rods 7 will drive the other set of rotating rods 7 to rotate. Due to the threaded engagement, the rotation of the rotating rods 7 will drive the sector bracket 2 to move along its axis towards the center of the support plate 4. When the sector bracket 2 is located at the center of the support plate 4, the first motor 6 is turned off.

[0031] At this time, the third motor 11 is started, which drives the second belt 14 to move in the belt groove 16 through the rotating shaft 15. Since the second belt 14 is fixedly connected to the fixed block 18, the second belt 14 will drive the radiation detector 3 to move when it moves in the belt groove 16. Since the trajectory of the belt groove 16 is arc-shaped and the axis of the arc is located at the center of the bearing plate 4, the second belt 14 will drive the radiation detector 3 to move, so that the movement trajectory of the radiation detector 3 and the cloud laser rangefinder 20 will be arc-shaped. No matter where the radiation detector 3 and the cloud laser rangefinder 20 move, they will be at the same distance from the center of the bearing plate 4. That is, the distance from the radiation detector 3 and the cloud laser rangefinder 20 to each surface of the object to be measured on the bearing plate 4 is the same.

[0032] When the radiation detector 3 makes an arc motion, it will drive the roller 19 to roll on the inner wall of the slide rail 17. The roller 19 supports the radiation detector 3 on the one hand, and rolls the relative movement between the radiation detector 3 and the sector bracket 2 on the other hand, thereby reducing friction. In addition, the trajectory of the slide rail 17 is arc-shaped and coaxial with the belt groove 16, so the roller 19 will not interfere when the second belt 14 drives the radiation detector 3 to move.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
