In view of this, alternative embodiments of the present disclosure are described in detail below with reference to the drawings.

Fig. 1 is a schematic view showing a structure of a door body in a closed state according to an exemplary embodiment. Fig. 2 is a schematic view showing a structure of a door body in an opened state according to an exemplary embodiment.

The disclosed embodiments provide a radiation shield 1000 for assembly to a hot cell, the radiation shield 1000 comprising: the door body 100, the door handle 110, the controller 200, and the driving motor 300.

In some embodiments, the door body 100 isolates the interior cavity of the radiation shield 1000 from the exterior space. The inner chamber is a radioactive working area, so that the door body 100 is used for separating the inner chamber from the outside space in order to reduce the damage of radioactive elements to workers in the field, and the safety of radiation biology is ensured for the workers in the field.

In some embodiments, the door handle 110 is disposed on an outer side surface of the door body 100, and a control button for controlling the movement of the door body 100 is disposed on the door handle 110. The controller 200 is connected to the control button, and the controller 200 receives a control signal generated from the control button and generates a driving signal.

In some embodiments, the driving motor 300 is connected to the controller 200 and receives the driving signal generated by the controller 200, where the driving signal makes the driving motor 300 work to provide power for the control button to control the movement of the door body 100.

Specifically, when the door body 100 of the radiation-proof door 1000 provided by the present disclosure needs to be moved, only a worker presses a control button on the door control handle 110, the control button transmits a control signal to the controller 200, and analysis is processed in the controller 200, and further, a driving signal is formed and transmitted to the driving motor 300. The driving motor 300 drives the door body 100 to move according to the received driving signal.

Compared with a hot chamber in the related art, the door body 100 of the radiation protection door 1000 provided by the disclosure can realize that the driving motor 200 drives the door body to open or close under the combined action of the controller 200, the control button and the driving motor 300, thereby saving a large amount of manpower and improving the working efficiency of staff to a certain extent.

In some embodiments, the control button comprises: a door opening button 111 for controlling the opening of the door body 100, and a door closing button 112 for controlling the closing of the door body 100.

When the door opening button 111 or the door closing button 112 continuously receives an external force, the controller 200 receives the door opening control signal or the door closing control signal and generates the driving signal, and the driving motor 300 performs a door opening or door closing operation on the door body 100 according to the received driving signal.

In some embodiments, a door opening signal line 101 and a door closing signal line 102 are disposed within the radiation shield 1000.

When the door opening button 111 is continuously subjected to an external force, a door opening control signal is generated, the door opening control signal is transmitted to the controller 200 through the door opening signal line 101, the controller 200 receives the door opening control signal and generates the door opening driving signal, and the driving motor 300 receives the door opening driving signal to perform a door opening operation on the door body 100.

When the door closing button 112 is continuously subjected to an external force, a door closing control signal is generated, the door closing control signal is transmitted to the controller 200 through the door closing signal line 102, the controller 200 receives the door closing control signal and generates the door closing driving signal, and the driving motor 300 receives the door closing driving signal to perform a door closing action on the door body 100.

In some embodiments, when the door body 100 is in the closed state, the door opening button 111 may be pressed for a long time to open the door body 100.

Specifically, when the door body 100 is in the closed state, the door opening button 111 is pressed for a long time, the door opening signal line 101 transmits a door opening control signal to the controller 200, and analysis is processed in the controller 200, and further, a door opening driving signal is formed to be transmitted to the driving motor 300. The driving motor 300 drives the door body 100 to switch from the closed state to the open state according to the received door opening driving signal.

In some embodiments, when the door 100 is in an open state, the door closing button 112 may be pressed for a long time to close the door 100.

Specifically, when the door body 100 is in the open state, the long-pressing door-closing button 112 transmits a door-closing control signal from the door-closing signal line 102 to the controller 200, and the controller 200 processes the door-closing control signal to analyze the door-closing control signal, and further, transmits a door-closing driving signal to the driving motor 300. The driving motor 300 drives the door body 100 to switch from the open state to the closed state according to the received door closing driving signal.

It should be noted separately that, if the external force applied to the control button is turned off during the movement of the door body 100, the control button no longer generates the control signal, that is, the driving motor 300 cannot receive the driving signal to drive the door body 100 to move continuously.

In some embodiments, when the door opening button 111 is continuously pressed, the driving motor 300 rotates forward to drive the door body 100 to open; when the door closing button 112 is continuously pressed, the driving motor 300 is reversed to drive the door body 100 to be closed.

In some embodiments, when the door body 100 is in the closed state, the door opening button 111 is pressed for a long time, and the door opening signal line 101 transmits the door opening control signal to the controller 200, and analysis is processed in the controller 200.

Further, a door opening driving signal is formed to be transmitted to the driving motor 300. The driving motor 300 receives the door opening driving signal, and then the driving motor 300 rotates forward to drive the door body 100 to switch from the closed state to the open state.

In some embodiments, when the door body 100 is in an open state, the door closing button 112 is pressed for a long time, a door closing control signal is transmitted to the controller 200 through the door closing signal line 102, and analysis is processed in the controller 200.

Further, a door closing driving signal is formed to be transmitted to the driving motor 300. The driving motor 300 is rotated reversely after receiving the door closing driving signal, so as to drive the door body 100 to switch from the open state to the closed state.

In some embodiments, the radiation shield 1000 further includes a radiation detection probe 400 disposed within the interior chamber, the radiation detection probe being coupled to the controller 200 for detecting radiation dose of the interior chamber.

Because the inner chamber of the radiation-proof door 1000 is a radioactive operation area, in order to avoid serious damage to staff caused by radioactive elements, a radiation monitoring probe for detecting the radiation dose of the inner chamber is arranged in the inner chamber, so that the door body 100 can be opened when the radiation dose in the inner chamber is kept within a safe range, and the radiation biosafety assurance is provided for the staff.

In some embodiments, the controller 200 has a preset radiation dose threshold.

When the radiation dose detected by the radiation monitoring probe is less than the radiation dose threshold, the controller 200 will receive the control signal and generate the drive signal, and the drive motor 300 receives the drive signal to move the door body 100.

When the radiation dose detected by the radiation monitoring probe is greater than or equal to the radiation dose threshold, the controller 200 receives the control signal but does not generate the driving signal, and at this time, the driving motor 300 is powered off and stopped, and the door body 100 does not move.

In some embodiments, when the door body 100 is in the closed state, the door opening button 111 is pressed for a long time, the door opening control signal is transmitted to the controller 200 through the door opening signal line 101, and analysis is processed in the controller 200. If the radiation dose detected by the radiation monitoring probe is less than the radiation dose threshold, the controller 200 will receive the door opening control signal and generate a door opening driving signal,

further, the driving motor 300 rotates forward after receiving the door opening driving signal to drive the door body 100 to switch from the closed state to the open state.

In some embodiments, the door 100 is self-locking when the door 100 is in a closed state, if the radiation dose detected by the radiation monitoring probe is greater than or equal to the radiation dose threshold.

Specifically, when the door body 100 is in the closed state, the door opening button 111 is pressed for a long time, and the door opening signal line 101 transmits a door opening control signal to the controller 200, and the analysis is processed in the controller 200.

If the radiation dose detected by the radiation monitoring probe is greater than or equal to the radiation dose threshold, the controller 200 receives the door opening control signal but does not generate the door opening driving signal, and the driving motor 300 is powered off and stopped at this time, and the door body 100 still keeps in a closed state and does not move.

In some embodiments, when the door body 100 is in an open state, the door closing button 112 is pressed for a long time, and the door closing signal line 102 transmits a door closing control signal to the controller 200, and analysis is processed in the controller 200. If the radiation dose detected by the radiation monitoring probe is less than the radiation dose threshold, the controller 200 will receive a door closing control signal and generate a door closing drive signal.

Further, the driving motor 300 rotates forward after receiving the door closing driving signal to drive the door body 100 to switch from the open state to the closed state.

In some embodiments, the radiation shield further comprises: a lead glass window 120 and the handle aperture 130.

The lead glass window 120 is provided on the door body 100 for viewing the inner chamber; the operating hand hole is arranged on the outer side surface of the door body and is used for entering the working area of the inner chamber to operate.

The door body 100 is provided with a lead glass window 120 and an operation hand hole 130 for entering the working area of the inner chamber, and a worker can extend both hands into the inner chamber from the operation hand hole 130 to perform work.

The lead glass window 120 is disposed at a central position of the door body 100, and when the door body 100 is in a closed state, the radiation monitoring probe 400 is located within an observation range of the lead glass window 120.

In practical application, if the radiation monitoring probe 400 is shifted, the monitoring result is easily biased, and a worker can directly observe the state of the radiation monitoring probe 400 in the inner cavity through the lead glass window 120, and when the radiation monitoring probe 400 is found to be shifted, the position of the radiation monitoring probe 400 is timely adjusted for opening the door body 100. When a worker works in the inner chamber through the operation hand hole 130, the inner chamber of the radiation-proof door 1000 can be seen through the lead glass window 120, so that the worker can work in the inner chamber, meanwhile, the radiation of the inner chamber to the worker can be reduced, and the radiation biosafety of the worker is ensured.

In some embodiments, the door body 100 is movably provided with a shutter 140 movably hinged to the outside of the door body 100 by a hinge structure and configured to be switched between an open position and a closed position.

In some embodiments, the hinge structure is provided with a resilient member configured to cause the shutter 140 to have a tendency to move toward the closed position.

The shutter 140 has an open position and a closed position on the door body 100, the shutter 140 being in the open position when the worker is performing a job; when the worker finishes his work, and pulls out both hands from the hand hole 130, the shutter 140 can be returned from the open position to the closed position due to the elastic member provided on the hinge structure 150.

In some embodiments, the door body 100 is a radiation-shielding door for shielding a radiation source inside the door body 100.

In some embodiments, the radiation shield also includes a seal 160, the seal 160 being disposed on an outer edge of the radiation shield for blocking radiation from escaping inside the radiation shield.

The outer edge of the radiation-proof shielding door is provided with a sealing structure 160 in a circumferential direction. Avoiding radiation leakage from the edges of the door body 100 provides a guarantee of radiation biosafety for workers in the field.

The material of the sealing structure 160 is not limited in this disclosure, and may be a sealing tape, or may be any sealing material other than a sealing tape, which can seal the edge of the door body 100.

Compared with the radiation-proof door assembled in the hot chamber in the related art, the door body 100 of the radiation-proof door 1000 provided by the disclosure can realize that the driving motor 200 drives the door body to open or close under the combined action of the controller 200, the door opening button 111, the door closing button 112 and the driving motor 300, thereby saving a great deal of manpower and improving the working efficiency of staff to a certain extent.
