Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way.

[0026] As Figures 1-2In the embodiment, the intelligent radioactive waste barrel comprises a structural unit and a measurement and control unit; the structural unit comprises an outer barrel 1 and a barrel cover 2 matched with the outer barrel 1, an electric control lock 3 is arranged between the barrel cover 2 and the outer barrel 1, a weighing device 4 is arranged in the outer barrel 1, an inner barrel 5 capable of sleeving a garbage bag 17 is arranged on the weighing device 4, an activity detection probe 6 for detecting the radioactive activity of garbage is arranged between the inner barrel 5 and the outer barrel 1, a garbage throwing opening corresponding to the inner barrel 5 is arranged on the barrel cover 2, an inner small cover 7 and an outer small cover 8 are arranged on the barrel cover 2 and matched with the garbage throwing opening, the inner small cover 7 and the outer small cover 8 are alternately sealed with the garbage throwing opening through a driving element 9, so that a garbage temporary storage cavity 10 is formed above the inner small cover 7 when the inner small cover 7 is matched with the garbage throwing opening, and the garbage in the garbage temporary storage cavity 10 falls into the inner barrel 5 when the outer small cover 8 is matched with the garbage throwing opening, the outer barrel 1, the barrel cover 2, the outer small cover 8, the inner small cover 7 and the garbage temporary storage cavity 10 are all protected by lead plates, and a throwing switch 11 for controlling the driving element 9 and a detection switch 12 for controlling the activity detection probe are arranged on the outer barrel 1 or the barrel cover 2.

[0027] The measurement and control unit comprises a controller, and the electric control lock 3, the weighing device 4, the activity detection probe 6, a weight alarm 13 and an activity alarm 14 connected with the controller, the weight alarm 13 is used for alarming when the garbage reaches a certain amount, and the activity alarm 14 is used for alarming when the garbage decays to a set value or below. In specific application, the weighing device 4 and the weight alarm 13 are linked to alarm when the throwing amount reaches the upper limit, the activity detection probe 6 and the electric control lock 3 are linked to lock the barrel cover 2 during detection and unlock the barrel cover 2 during non-detection, and the activity detection probe 6 and the activity alarm 14 are linked to alarm when the garbage reaches a decay standard value or below.

[0028] Working principle:

[0029] Before use, the barrel cover 2 is opened, a garbage bag is sleeved on the inner barrel 5, and then the barrel cover 2 is covered, so that the activity detection probe 6 starts to work, and at the same time, the barrel cover 2 and the outer barrel 1 are locked through the electric control lock 3, so as to avoid the barrel cover 2 from being opened by mistake during use, and reduce the risk of radiation leakage of radioactive garbage.

[0030] Before garbage is thrown in, the weight of the garbage is zero, and at this time, the activity alarm 14 does not alarm; when radioactive garbage is thrown in, the driving element 9 is started through the throwing switch 11, the outer small cover 8 is first opened to expose the garbage temporary storage cavity 10 for garbage throwing, and then the outer small cover 8 is closed and the inner small cover 7 is opened, so that the garbage in the garbage temporary storage cavity 10 falls into the inner barrel 5, thereby completing a garbage throwing process. In this way, the risk of radiation leakage of the garbage in the barrel during the garbage throwing process can be effectively reduced.

[0031] With the increase of the weight of the garbage, the activity data will be detected by the activity detection probe 6, and the probe measurement range can be 0.01 μSv / h-100 mSv / h, and the type can be selected. When the weight of the garbage measured by the weigher 4 exceeds the upper limit value, the weight alarm 13 will alarm and timely inform the staff that no new garbage will be put in; before the garbage exceeds the upper limit value, the activity data of the new garbage will increase, and the activity data of the already put-in garbage will decrease, so the activity data is always changing in this process. If the activity data of the garbage decays below the standard value before the weight of the garbage exceeds the upper limit value, the activity alarm 14 can be set to alarm at this time to inform the staff that the garbage can be taken out at any time, and of course it can also be set to the form that the activity alarm will alarm only after the garbage reaches the upper limit value.

[0032] When the garbage meets the safety standard and can be taken out, the activity detection probe 6 is closed, the electric control lock 3 is unlocked, and the barrel cover 2 is opened to take out the garbage.

[0033] In one specific embodiment, the weight alarm 13 can specifically adopt an indicator light, that is, when the weight reaches the upper limit, the indicator light can be turned on to know that the garbage in the waste barrel is full, which is more intuitive. The activity alarm 14 can adopt an indicator light or a buzzer, which is convenient for close-range observation, and the buzzer is convenient for some distance notification.

[0034] In one specific embodiment, the measurement and control unit further comprises a touch screen 15 connected to the controller, which can output garbage putting records, putting frequency, real-time activity data of the garbage and other parameters. The staff can find and view at any time according to needs.

[0035] In one specific embodiment, the measurement and control unit further comprises a driving member 9 connected to the controller, and the driving member 9 is linked with the weigher 4 to lock the driving member when a certain amount of garbage is put in, so as to lock the outer small cover 8 and the inner small cover 7, which is more secure.

[0036] In one specific embodiment, the putting switch 11 can adopt a pedal switch, which is more convenient. When putting, the pedal is stepped on to make the driving member 9 open the outer small cover 8 to put in the garbage; after the putting is completed, the pedal is released, the outer small cover 8 closes the inner small cover 7 to open to realize the garbage falling into the cylinder.

[0037] In one specific embodiment, the structure of the driving member 9 can specifically comprise a rotating shaft rotatingly arranged on the barrel cover 2, the outer small cover 8 and the inner small cover 7 are eccentrically fixed on the rotating shaft, and the two are staggered, and the rotating shaft is driven by a servo motor and a gear set arranged on the barrel cover. When the pedal is stepped on, the motor drives the rotating shaft to rotate forward, and then drives the outer small cover 8 to open and the inner small cover 7 to close; when the pedal is released, the motor drives the rotating shaft to rotate reversely, and then drives the outer small cover 8 to close and the inner small cover 7 to open.

[0038] In one of the specific embodiments, the activity detection probe 6 is arranged at the bottom of the outer barrel 1 below the inner barrel 5 to monitor the surface dose rate of the waste in real time and automatically transmit the real-time value to the touch screen to facilitate the intelligent reminding of the staff to timely handle the waste that has decayed to the standard.

[0039] In one of the specific embodiments, the barrel cover 2 is hinged to the outer barrel 1, and the top of the barrel cover 2 is provided with an opening handle 16 to facilitate the opening and closing of the barrel cover.

[0040] In one of the specific embodiments, the waste barrel can be used in cooperation with a radioactive monitoring platform to remotely and comprehensively monitor the on-site waste barrel, so as to reduce the radioactive irradiation caused by repeated close-range viewing and measurement of personnel, ensure the effective storage and disposal of radioactive waste, and be suitable for multiple fields such as customs, environmental protection and medical treatment. The remote communication mode can be any one of RS485, LAN and WiFi.

[0041] The above specific embodiments cannot be regarded as a limitation on the protection scope of the utility model, and any alternative improvement or change made by the person skilled in the art to the embodiments of the utility model falls within the protection scope of the utility model.

[0042] The parts not described in the utility model are the known technology of the person skilled in the art.
