Description

Technical Field

[0001] The utility model belongs to the technical field of radiation shielding performance detection devices, and particularly relates to a radiation protection door shielding performance detection device. Background Technique

[0002] Radiation protection is an important branch of atomic energy science and technology. It is a comprehensive interdisciplinary subject that studies how humans can be protected from or less exposed to the hazards of ionizing radiation. Its basic task is to protect the health and safety of personnel engaged in radioactive work, the public and their future generations, protect the environment, and promote the development of the atomic energy industry; the main contents of radiation protection research include radiation dosimetry, radiation protection standards, radiation protection technologies, radiation protection evaluations, and radiation protection management, etc.

[0003] At present, the radiation protection products on the market are mainly radiation protection doors. During the production and manufacturing process of radiation protection doors, multiple detections are required. However, the detection equipment for radiation protection doors on the market is rather troublesome to use, and it is difficult to comprehensively detect radiation protection doors during a single detection process, resulting in a reduction in detection efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a radiation protection door shielding performance detection device, which solves the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a radiation protection door shielding performance detection device, including a base. A blanking table is fixedly connected to the side of the base, and a detection chamber is fixedly connected to the top of the base. First detectors are arranged on the inner walls of the front end and the rear end of the detection chamber, and a second detector is arranged on the inner top of the detection chamber. Shielding curtains are arranged on both sides of the detection chamber. A rotating conveying mechanism is arranged inside the base. The rotating conveying mechanism includes a motor, a chute, and a toothed rod. The motor is fixedly installed on one side of the base away from the blanking table. The motor is fixedly connected to a threaded rod through its output shaft. The threaded rod is rotatably connected inside the base. The chute is opened on the top of the base. A slider is slidably connected inside the chute. The slider is threadedly connected to the threaded rod. A rotating shaft is rotatably connected to the top of the slider. A placement plate is fixedly connected to the top of the rotating shaft. A gear is fixedly connected to the middle end of the rotating shaft. The toothed rod is fixedly connected to the top of the base. An automatic clamping and blanking mechanism is arranged inside the placement plate.

[0007] Furthermore, the toothed rod is located inside the detection chamber, and the teeth on the toothed rod are adapted to the teeth on the gear. When the gear moves to the position of the toothed rod, it will engage with the teeth on the toothed rod, and at this time, the gear will rotate when it continues to move.

[0008] Furthermore, the length of the threaded rod is greater than the length of the sliding groove, and the length of the sliding groove is greater than the length of the detection chamber. When the threaded rod rotates, it drives the slider to move within the sliding groove, and the slider can move from the outside of one end of the detection chamber to the outside of the other end.

[0009] Furthermore, the overall material of the shielding curtain is a metal fiber mixed fabric material, and the shielding curtain made of the metal fiber mixed fabric material can reduce or shield the electromagnetic radiation and radio wave radiation emitted from within the detection chamber.

[0010] Furthermore, the automatic clamping and blanking mechanism includes a hydraulic chamber and a blocking block. The hydraulic chamber is fixedly connected inside the placement plate. A piston of one end inner wall of the hydraulic chamber is slidably connected to a pull rod. The end of the pull rod away from the hydraulic chamber is fixedly connected to a pull plate. Pistons of both ends inner walls of the hydraulic chamber away from the pull rod are slidably connected to clamping rods. The end of the clamping plate away from the hydraulic chamber is fixedly connected to a clamping plate. A compression spring is sleeved on the surface of the clamping rod, and the blocking block is fixedly connected to the top of the base.

[0011] Furthermore, both ends of the compression spring are in contact with the hydraulic chamber and the clamping plate in the initial state. When the clamping rod moves into the hydraulic chamber, the compression spring will be gradually tightened under extrusion.

[0012] Furthermore, the material of the clamping plate is rubber. The blocking block is located outside one end of the detection chamber close to the blanking table. When the rubber clamping plate clamps the radiation protection door, it is relatively stable. When the placement plate moves to the outside of one end of the detection chamber close to the blanking table, the pull plate will contact the blocking block.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting up a rotating conveying mechanism, the utility model achieves the effect that after the radiation protection door is placed upright on the placement plate, the motor can be started. At this time, through the cooperation of components such as the threaded rod, sliding groove, slider, gear, and tooth rod, the placement plate and the radiation protection door thereon will be driven to move leftward into the detection chamber for detection. At the same time, it will also rotate when moving within the detection chamber, achieving the effect of comprehensively detecting the radiation protection door.

[0015] 2. By setting up an automatic clamping and blanking mechanism, the utility model achieves the effect that through the cooperation of components such as the hydraulic chamber, pull rod, clamping rod, and clamping plate, the radiation protection door standing on the placement plate can be clamped. When the placement plate moves to the blanking table, the clamping plate will automatically release the radiation protection door. At this time, by gently colliding the slider with one end of the sliding groove close to the blanking table, the radiation protection door standing on the anti-collision placement plate can be unloaded, saving the time of manual blanking.

[0016] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figures 1-5, the utility model is a detection device for the shielding performance of a radiation protection door, which includes a base 1. A blanking table 2 is fixedly connected to the side of the base 1. A detection chamber 3 is fixedly connected to the top of the base 1. First detectors 4 are arranged on the inner walls of the front end and the rear end of the detection chamber 3. A second detector 5 is arranged at the top inside the detection chamber 3. Shielding curtains 6 are arranged on both sides of the detection chamber 3. A rotating conveying mechanism 7 is arranged inside the base 1. The rotating conveying mechanism 7 includes a motor 71, a chute 73 and a rack 78. The motor 71 is fixedly installed on one side of the base 1 away from the blanking table 2. The motor 71 is fixedly connected to a threaded rod 72 through its output shaft. The threaded rod 72 is rotationally connected inside the base 1. The chute 73 is opened on the top of the base 1. A slider 74 is slidably connected inside the chute 73. The slider 74 is threadedly connected to the threaded rod 72. The top of the slider 74 is rotationally connected to a rotating shaft 75. The top of the rotating shaft 75 is fixedly connected to a placement plate 76. The middle end of the rotating shaft 75 is fixedly connected to a gear 77. The rack 78 is fixedly connected to the top of the base 1. An automatic clamping and blanking mechanism 8 is arranged inside the placement plate 76.

[0027] The rack 78 is located inside the detection chamber 3, and the teeth on the rack 78 are adapted to the teeth on the gear 77. When the gear 77 moves to the position of the rack 78, it will engage with the teeth on the rack 78, and at this time, the gear 77 will rotate when it continues to move.

[0028] The length of the threaded rod 72 is greater than the length of the chute 73. The length of the chute 73 is greater than the length of the detection chamber 3. When the threaded rod 72 rotates, it will drive the slider 74 to move inside the chute 73, and the slider 74 can move from the outside of one end of the detection chamber 3 to the outside of the other end.

[0029] The overall material of the shielding curtain 6 is a metal fiber mixed fabric material. The shielding curtain 6 made of the metal fiber mixed fabric material can reduce or shield the electromagnetic radiation and radio wave radiation emitted from inside the detection chamber 3.

[0030] The automatic clamping and blanking mechanism 8 includes a hydraulic chamber 81 and a stopper 87. The hydraulic chamber 81 is fixedly connected inside the placement plate 76. A pull rod 82 is slidably connected to the piston on one end inner wall of the hydraulic chamber 81. The end of the pull rod 82 away from the hydraulic chamber 81 is fixedly connected to a pull plate 83. Clamping rods 84 are slidably connected to the pistons on both ends inner walls of the hydraulic chamber 81 away from the pull rod 82. The end of the clamping rod 84 away from the hydraulic chamber 81 is fixedly connected to a clamping plate 85. A compression spring 86 is sleeved on the surface of the clamping rod 84. The stopper 87 is fixedly connected to the top of the base 1.

[0031] Both ends of the compression spring 86 are initially in contact with the hydraulic chamber 81 and the clamping plate 85. When the clamping rod 84 moves into the hydraulic chamber 81, the compression spring 86 will be gradually tightened under extrusion.

[0032] The clamping plate 85 is made of rubber. The abutting block 87 is located outside one end of the detection bin 3 close to the blanking table 2. When the rubber clamping plate 85 clamps the radiation protection door, it is relatively stable. When the placing plate 76 moves to the outside of one end of the detection bin 3 close to the blanking table 2, the pull plate 83 will contact the abutting block 87.

[0033] A specific application of this embodiment is as follows: When performing detection work, place the radiation protection door upright on the placing plate 76, start the motor 71 to drive the threaded rod 72 to rotate. The rotation of the threaded rod 72 will drive the slider 74 to move to the right along the chute 73. The rightward movement of the slider 74 drives the placing plate 76 and the radiation protection door thereon to move to the right into the detection bin 3 through the rotating shaft 75. At this time, the first detector 4 and the second detector 5 will detect the radiation protection door. During the movement of the rotating shaft 75 in the detection bin 3, the gear 77 at the middle end thereof will mesh with the toothed rod 78 and thus rotate. The rotation of the gear 77 drives the rotating shaft 75 to rotate, and the rotation of the rotating shaft 75 drives the placing plate 76 and the radiation protection door thereon to rotate, so as to achieve the effect of comprehensively detecting the radiation protection door. When the radiation protection door needs to be clamped after being placed upright on the placing plate 76, the pull plate 83 can be pulled to the left first to drive the pull rod 82 to move to the left. The leftward movement of the pull rod 82 will drive the hydraulic pressure in the hydraulic bin 81 to drive the two clamping rods 84 to move into the hydraulic bin 81, so as to separate the two clamping plates 85, and the compression spring 86 is tightened. At this time, place the radiation protection door between the two clamping plates 85 and release the pull plate 83. At this time, the compression spring 86 will rebound to drive the two clamping plates 85 to move closer to clamp the radiation protection door, and the two clamping rods 84 move out of the hydraulic bin 81, and the pull rod 82 and the pull plate 83 move to the left. When the placing plate 76 moves out from the other end of the detection bin 3, the pull plate 83 will contact the abutting block 87 and stop moving. At this time, when the placing plate 76 continues to move towards the blanking table 2, it will cause the pull rod 82 to move out of the hydraulic bin 81. The movement of the pull rod 82 out of the hydraulic bin 81 causes the hydraulic pressure in the hydraulic bin 81 to drive the two clamping rods 84 and the clamping plate 85 to separate and release the radiation protection door. Subsequently, when the slider 74 gently collides with one end of the chute 73 close to the blanking table 2, the radiation protection door will fall onto the blanking table 2 due to inertia to complete blanking, saving the time of manual blanking.
