The utility model discloses an application principle does:

fixed protection body and removal protection body are detachable construction, and wherein, support column and crossbeam are as the frame, can not replace, and baffle structures such as main baffle and side shield all through the fix with screw on support column or crossbeam, to the application scene of difference, its specification is selectable, the baffle of different material thickness, the effect of blockking to the ray is different. Therefore, before the device is used in a radioactive place, a baffle plate with a proper specification is selected after calculation according to the type and the intensity of rays, and then the baffle plate is installed on a frame consisting of supporting columns and cross beams.

The second main baffle 2 acts as a frontal shield, the lower edge of which is lower than the first cross member 15, close to the ground, with the aim of reducing as much as possible the radiation damage of the frontal rays.

When the height of the movable protection body is adjusted, the pulley 10 is beneficial to reducing the friction force, so that the adjustment process is easier; the U-shaped structure of the fourth supporting column 8 can play a limiting role and prevent the moving protection body from falling off.

The cross section of the first supporting column 5 is trapezoidal, and is as thin as possible on the premise of ensuring mechanical strength and blocking rays, so that the weight of the movable protective body is reduced, and the movable protective body is convenient to lift.

The outer side of the second supporting column 6 is outwards provided with an arc-shaped bulge, the design aims at thickening the second supporting column 6, otherwise, a pin hole 17 is formed in the middle of the second supporting column 6, so that the mechanical strength of the second supporting column is reduced, and a local area is at risk of being penetrated by rays; the pin holes 17 are angled obliquely downwards, as shown in fig. 8, in order to increase the effective thickness of the second support column 6 in the horizontal direction on the one hand and to help prevent the positioning pins 9 from falling out of the pin holes 17 on the other hand.

The first embodiment is as follows:

before the use, the user need adjust the height of removing the protection body again according to oneself height, and its principle makes the height of handle 11 unanimous basically with oneself face height, and after the height is confirmed, inserts locating pin 9 in the pinhole 17 that removes the protection body bottom border nearest, makes it hold and removes the protection body. The force acts on the first support column 5 and the second support column 6, and the mechanical strength of the support columns is far greater than that of the baffle, so that the baffle can be prevented from being deformed due to long-term use.

Example two:

in some cases, the protection object needs to know whether the radiation intensity is low enough to be acceptable to human body. It is therefore necessary to resort to the radiation sensor 13, of the type DH80-G, mounted on the mobile shielding body. The control box is fully charged in advance and placed on the control box bracket 12, a contact of the control box contacts a contact of the control box bracket 12, a power supply of the control box is turned on, a control chip in the control box is connected with the ray sensor 13 and the indicator lamp 14 through the contact, when the fact that a signal fed back by the ray sensor 13 still exceeds a safety value is detected, the indicator lamp is continuously turned on, the indicator lamp is turned off until the signal fed back by the ray sensor 13 is lower than the safety value, and a protection object can only be taken out of the protection body.

The control box is designed based on a C8051F340 industrial-grade single chip microcomputer, the C8051F340 single chip microcomputer is connected with a DH80-G type ray inductor through an MAX485 chip through a serial port, and data interaction is carried out, so that real-time monitoring on the radiation intensity is realized.

Example three:

the second embodiment is still relatively complicated and not straightforward in some cases. In this regard, the viewing window 20 may be added to the baffle.

The observation window 20 is covered with lead glass with lead equivalent of 2-3 mmPb, which not only has radiation protection function, but also provides a visual medium. Thus, the operator can directly observe the basic conditions of the ray device or the radiation source, the state of the patient, the instrument positioning and the like through the lead glass.
