Description

Technical Field

[0001] The utility model relates to the technical field of irradiation, in particular to a closing detection device for an irradiation container door. Background Art

[0002] Irradiation is a chemical technology that uses the radiation of radioactive elements to change the molecular structure. Through irradiation, the long linear macromolecules between polymer materials are connected by a certain form of chemical bonds to form a network structure, which can greatly enhance the binding force between polymers, thereby enhancing the thermal stability, flame retardancy, chemical stability, drip resistance, strength and stress cracking resistance of the material. There are many ways of irradiation, such as x-rays, high-speed electron flow, etc. In irradiation processing, a tray is often used in the irradiation device. If the tray door is not closed and the irradiation room is entered, when passing through the source mechanism, the open tray door collides with the radiation source rack, which will cause damage to the radiation source, or cause the radiation source rack to be blocked when descending, resulting in serious safety accidents.

[0003] The existing Chinese patent CN208366356U disclosed a closing detection device for an irradiation box door on January 11, 2019, including a box body, a box door, a processor, an indicator light, a first contact block and a second contact block. The box door is installed on one side of the box body, and one side of the box door is hinged to the box body through a first connecting member and a second connecting member. A closing lock is installed in the middle of one end of the box door, and a first contact block is installed at one end of the closing lock. A second contact block is installed on one side of the box body, and the first contact block and the second contact block are arranged correspondingly. A processor, an alarm and an indicator light are installed on one side of the box body, and the alarm and the indicator light, the first contact block and the second contact block are electrically connected to the processor. A supporting foot is installed on the lower side of the box body.

[0004] However, the above device uses two correspondingly installed contacts to perform inductive detection. During long-term use, the contacts are easily deformed and damaged due to contact between the two contacts, which may easily lead to inaccurate detection and make the device unsafe to use.

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a closing detection device for an irradiation tray door is proposed. During detection, the laser corresponding detection mechanism transmits the detection information to the control chassis.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A closing detection device for an irradiation box door comprises an irradiation box body, a placement support foot and a moisture-proof bottom plate, wherein the irradiation box body is installed and connected to the upper end position of the moisture-proof bottom plate, the lower end of the moisture-proof bottom plate is provided with a placement support foot, the upper end of the irradiation box body is provided with a control cabinet, the outer side of the control cabinet is provided with an audible and visual alarm on the irradiation box body, the front end of the irradiation box body is provided with an irradiation box door body, the left end of the irradiation box door body is movably connected to the irradiation box body through a door rotating block, the outer end of the door rotating block is provided with a closing rotating mechanism on the irradiation box body, and a laser corresponding detection mechanism is provided at the right end corner of the irradiation box door body, and the control cabinet, the laser corresponding detection mechanism, the closing rotating mechanism and the audible and visual alarm are electrically connected via a connecting line.

[0008] Through the above technical scheme: the irradiation tray box body can be supported and placed for use due to the supporting feet placed at the lower end of the moisture-proof bottom plate. When the closing rotating mechanism rotates in the forward direction, the closing rotating mechanism can drive the box door rotating block to rotate, and the box door rotating block drives the irradiation tray door body to close on the irradiation tray box body, and then the laser corresponding detection mechanism at the right corner of the irradiation tray door body performs laser corresponding closing detection, and the laser corresponding detection mechanism transmits the detection information to the control chassis. When the data received by the control chassis detects that the irradiation tray door body and the irradiation tray box body are not completely closed, the sound and light alarm emits sound and light for prompting, and when it is completely closed, the sound and light alarm stops, so that the overall closing detection is more accurate and convenient.

[0014] Through the above technical solution: due to the rotating block structure of the box door, it can be used in a limited rotation.

[0015] The utility model is further configured that the laser corresponding detection mechanisms are provided with two in total, and the laser corresponding detection mechanisms are symmetrically arranged at the right end corner of the irradiation box door body.

[0016] Through the above technical solution: because there are two laser corresponding detection mechanisms in total, and the laser corresponding detection mechanisms are symmetrically arranged on the right end corner of the irradiation box door body, corresponding sensing can be performed on both sides.

[0023] The beneficial effects of the utility model are:

[0024] 1. The detection information is transmitted to the control box through the laser corresponding detection mechanism. When the data received by the control box detects that the irradiation tray door body and the irradiation tray box body are not completely closed, the sound and light alarm will emit sound and light to prompt. When they are completely closed, the sound and light alarm will stop, so that the overall closure detection is more accurate and convenient.

The emitting body shell of the laser corresponding detection mechanism is adhered and connected to the irradiation tray box body, so that the emitting body shell is easy to install and place, and the receiving body shell is adhered and connected to the irradiation tray door body, so that the receiving body shell is easy to install and place. When the laser transmitter body on the inner side of the lower end of the emitting body shell emits a laser, if it is not received by the laser receiver body on the inner side of the upper end of the receiving body shell, it means that the irradiation tray door body is not tightly closed with the irradiation tray box body. Through the corresponding induction of the laser, the sensing error caused by deformation during long-term use can be effectively avoided, which is safer when used. BRIEF DESCRIPTION OF THE DRAWINGS
