Technical Field

[0001] This utility model relates to the field of irradiation box technology, specifically to an automatic metering and control irradiation box. Background Technology

[0002] An irradiation chamber is a device that uses radiation technology to treat objects. It has a wide range of applications in various fields. Generally, it treats objects by irradiating them with high-energy rays that can penetrate objects and interact with the matter. However, existing irradiation chambers have some shortcomings, such as:

[0003] Application No.: CN202020145920.3 describes a single-layer irradiation chamber. This equipment can be designed in multiple height models to accommodate materials of varying heights, achieving versatility. It is convenient for loading and unloading, easy to operate, and quick and easy to clean, making it suitable for irradiation treatment. However, in actual use, it is difficult to monitor the intensity of the radiation generated by the internal irradiation equipment, which may lead to uncontrollable problems when controlling the intensity of the irradiation equipment.

[0004] Therefore, we propose an automatic metering and control irradiation chamber to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an automatic metering and control irradiation box to solve the problem mentioned in the background art that current irradiation boxes on the market are difficult to monitor and adjust the irradiation intensity of irradiation equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic metering and control irradiation box, comprising a main body and a closed door hinged to the front end of the main body, a cooler installed on the top of the main body, and a ventilation valve installed on the left end of the main body.

[0007] The device body has a drive mechanism on the right side, and the top of the drive mechanism is connected to the irradiation mechanism, and the bottom of the drive mechanism is connected to the rotation mechanism. The device body has a protective mechanism inside, and the protective mechanism is located at both ends of the outer side of the rotation mechanism.

[0008] The irradiation mechanism includes a reciprocating threaded shaft, and a first threaded sleeve is provided on the outside of the reciprocating threaded shaft, and an irradiation device is installed at the bottom of the first threaded sleeve;

[0009] The bottom of the main body of the device is connected to the rotating mechanism, and an infrared camera is installed on the top of the protective mechanism. A radiation dosimeter is installed at the rear of the protective mechanism and is connected to the circuit of the irradiation equipment.

[0010] By installing infrared cameras and radiation dosimeters on the outside of the protective structure, the irradiation equipment can monitor the temperature on the outside of the object during irradiation operations. At the same time, the radiation dosimeter can monitor the irradiation intensity. This allows the equipment to be adjusted based on the feedback from the infrared cameras and radiation dosimeters when the irradiation is too strong or too weak, thus preventing the irradiation equipment from exceeding the preset range.

[0011] As a preferred technical solution of this utility model, the main body of the device is connected to the drive mechanism, and the drive mechanism includes a first motor, and a first sprocket is connected to the left end of the first motor. A chain is engaged on the outside of the first sprocket, and a second sprocket is engaged at the bottom end of the chain. Both the first sprocket and the second sprocket are provided with ratchet groups on their left ends.

[0012] The above technical solution makes it easier for the drive mechanism to move the irradiation equipment or rotate the rotary table, thereby increasing the controllability of the equipment during operation.

[0013] As a preferred technical solution of this utility model, the second sprocket is connected to the inside of the device body through a bearing seat, and the ratchet group includes a first ratchet, and the second ratchet is engaged at the left end of the first ratchet. A spring shaft is installed at the left end of the second ratchet, and the ratchet group at the left end of the first sprocket and the ratchet group at the left end of the second sprocket face opposite directions.

[0014] The above technical solution enables the drive mechanism to be more stable when controlling the irradiation mechanism or the rotation mechanism, thereby increasing the controllability of the equipment during operation.

[0015] As a preferred technical solution of this utility model, the left end of the first sprocket is connected to the reciprocating threaded shaft via a ratchet, and the main body of the device is provided with a first limiting rod, which is slidably connected to the first threaded sleeve.

[0016] The above technical solution enables the drive mechanism to be more stable when connected to the reciprocating threaded shaft, thereby increasing the stability of the equipment during operation.

[0017] As a preferred technical solution of this utility model, the left end of the second sprocket is connected to the rotating mechanism through a ratchet assembly, and the rotating mechanism includes a drive shaft, and the left end of the drive shaft is connected to a first bevel gear, the top of the first bevel gear meshes with a second bevel gear, and a rotating table is mounted on the top of the second bevel gear.

[0018] The above technical solution enables the drive mechanism to be more stable when rotating the turntable, thus making the turntable more stable when rotating the object.

[0019] As a preferred technical solution of this utility model, the second bevel gear is connected to the main body of the device through a bearing seat, and the protective mechanism includes a second motor, and a threaded rod is connected to the right end of the second motor. Two sets of second threaded sleeves are provided on the outside of the threaded rod, and a first limiting plate and a second limiting plate are respectively connected to the top of the two sets of second threaded sleeves. The first limiting plate is fixedly connected to the infrared camera and the radiation dosimeter, and the thread grooves inside the two sets of second threaded sleeves are in opposite directions.

[0020] The above technical solution enables the infrared camera and radiation dosimeter to observe the rotating object at close range while the first limiting plate protects the outside of the rotating object, thus avoiding the problem of difficulty in observation when the object is too large or too small.

[0021] As a preferred technical solution of this utility model, the bottom of the main body of the device is provided with a second limiting rod, and the second limiting rod is slidably connected to the second threaded sleeve. An integrated control board is provided at the front end of the closed door. The integrated control board is connected to the irradiation equipment and the radiation dosimeter. The radiation dosimeter is a GQGMC radiation dose rate meter.

[0022] The above technical solution enables the two sets of second threaded sleeves to slide more stably, and allows the irradiation equipment and radiation dosimeter to be controlled through an integrated control board.

[0023] Compared with the prior art, the beneficial effects of this utility model are: by setting an infrared camera and a radiation dosimeter on the outside of the protective mechanism, the irradiation equipment can monitor the temperature on the outside of the item through the infrared camera when irradiating the item, and the radiation dosimeter can also monitor the irradiation intensity. Thus, when the irradiation of the irradiation equipment is too strong or too weak, it can be adjusted through the information fed back by the infrared camera and the radiation dosimeter, thereby avoiding the situation where the irradiation equipment exceeds the preset range.

[0024] Furthermore, by setting up the drive mechanism, it becomes easier to move the irradiation equipment or rotate the rotary table, thereby increasing the controllability of the equipment during operation.

[0025] Furthermore, by fixing the infrared camera and radiation dosimeter with the first limiting plate, the infrared camera and radiation dosimeter can be observed at close range while the first limiting plate protects the outside of the rotating object, thus avoiding the problem of difficulty in observation when the object is too large or too small.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] To address the difficulty in controlling the irradiation dose of materials in existing technologies, the following solution is disclosed. Please refer to [link / reference]. Figures 1-6 This utility model provides a technical solution: an automatic metering and control irradiation box, including a device body 1 and a closed door 2 hinged to the front end of the device body 1. A cooler 28 is installed on the top of the device body 1, and a ventilation valve 26 is installed on the left end of the device body 1.

[0035] The device body 1 has a drive mechanism on the right side, and the top of the drive mechanism is connected to the irradiation mechanism, and the bottom of the drive mechanism is connected to the rotation mechanism. The device body 1 has a protective mechanism inside, and the protective mechanism is located at both ends of the outer side of the rotation mechanism.

[0036] The irradiation mechanism includes a reciprocating threaded shaft 10, and a first threaded sleeve 11 is provided on the outside of the reciprocating threaded shaft 10, and an irradiation device 13 is installed at the bottom of the first threaded sleeve 11.

[0037] The bottom of the main body 1 is connected to the rotating mechanism, and an infrared camera 24 is installed on the top of the protective mechanism. A radiation dosimeter 25 is installed at the rear end of the protective mechanism, and the radiation dosimeter 25 is electrically connected to the irradiation equipment 13.

[0038] The device body 1 is connected to the drive mechanism, and the drive mechanism includes a first motor 3. The left end of the first motor 3 is connected to a first sprocket 4. A chain 5 is engaged on the outside of the first sprocket 4, and a second sprocket 6 is engaged at the bottom end of the chain 5. Both the first sprocket 4 and the second sprocket 6 are provided with ratchet groups on their left ends.

[0039] The second sprocket 6 is connected to the inside of the device body 1 through a bearing seat, and the ratchet group includes a first ratchet 7, and the left end of the first ratchet 7 is engaged with a second ratchet 8. A spring shaft 9 is installed on the left end of the second ratchet 8, and the ratchet group on the left end of the first sprocket 4 and the ratchet group on the left end of the second sprocket 6 face opposite directions.

[0040] The left end of the first sprocket 4 is connected to the reciprocating threaded shaft 10 via a ratchet, and the main body 1 of the device is provided with a first limiting rod 12, and the first limiting rod 12 is slidably connected to the first threaded sleeve 11.

[0041] The left end of the second sprocket 6 is connected to the rotating mechanism via a ratchet assembly, and the rotating mechanism includes a drive shaft 14, and the left end of the drive shaft 14 is connected to a first bevel gear 15, the top of the first bevel gear 15 is engaged with a second bevel gear 16, and a rotating table 17 is mounted on the top of the second bevel gear 16.

[0042] The second bevel gear 16 is connected to the main body 1 of the device through a bearing seat, and the protective mechanism includes a second motor 18, and a threaded rod 19 is connected to the right end of the second motor 18. Two sets of second threaded sleeves 21 are provided on the outside of the threaded rod 19, and the top of the two sets of second threaded sleeves 21 are respectively connected to a first limiting plate 22 and a second limiting plate 23. The first limiting plate 22 is fixedly connected to the infrared camera 24 and the radiation dosimeter 25, and the thread grooves inside the two sets of second threaded sleeves 21 are in opposite directions.

[0043] The device body 1 has a second limiting rod 20 at the bottom, and the second limiting rod 20 is slidably connected to the second threaded sleeve 21. The front end of the closed door 2 has an integrated control board 27, which is connected to the irradiation equipment 13 and the radiation dosimeter 25. The radiation dosimeter 25 is a GQGMC radiation dose rate meter.

[0044] Working principle: When using this automatic metering and control irradiation chamber, first connect the equipment power supply and the power grid. Then, the cooler 28 transmits cold air to the interior of the main body 1 for ventilation, thereby reducing bacteria inside the main body 1. Next, place the item on top of the rotating mechanism. Simultaneously, the drive mechanism drives the irradiation mechanism, causing the reciprocating threaded shaft 10 to move the first threaded sleeve 11, which in turn moves the irradiation device 13 to the designated position. Then, the protective mechanism is activated, protecting the outside of the item. Simultaneously, the protective mechanism also protects the infrared camera 24 and the radiation agent. The dosimeter 25 moves to the outside of the object, thereby causing the drive mechanism to rotate the rotating mechanism, which in turn causes the irradiation equipment 13 to start irradiating the rotating object. At this time, the radiation dosimeter 25 will monitor the object, and the infrared camera 24 will also monitor the temperature of the object. When the irradiation threshold of the irradiation equipment 13 deviates (e.g., it is set to 20μSv / h-70μSv / h, but is lower than 20μSv / h or higher than 70μSv / h), the radiation dosimeter 25 will transmit the data to the irradiation equipment 13, so that the irradiation equipment 13 can increase or decrease the power through the central processing unit or other control equipment.

[0045] When the drive mechanism is running, the first motor 3 drives the first sprocket 4 to rotate, which in turn drives the second sprocket 6 to rotate via the chain 5. When the first sprocket 4 rotates in the forward direction, the ratchet assembly at the left end of the first sprocket 4 will engage, that is, the first ratchet 7 and the second ratchet 8 will engage. The second ratchet 8 will then drive the reciprocating threaded shaft 10 to rotate via the spring shaft 9. Since the ratchet assembly at the left end of the first sprocket 4 and the ratchet assembly at the left end of the second sprocket 6 face opposite directions, the ratchet assembly at the left end of the second sprocket 6 will disengage, that is, the first ratchet 7 and the second ratchet 8 will disengage. The second ratchet 8 will then retract under the drive of the spring shaft 9.

[0046] When the second sprocket 6 rotates in the opposite direction, it will drive the drive shaft 14 to rotate through the ratchet assembly, thereby causing the first bevel gear 15 to drive the second bevel gear 16 and the rotating table 17 to rotate, which enables the rotating table 17 to drive the item to rotate.

[0047] When the protective mechanism is in operation, the second motor 18 will drive the threaded rod 19 to rotate, which will cause the threaded rod 19 to drive the two sets of second threaded sleeves 21 to move towards each other, thereby causing the first limiting plate 22 and the second limiting plate 23 to move towards each other. The first limiting plate 22 will also drive the infrared camera 24 and the radiation dosimeter 25 to move to the outside of the object.

[0048] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
