Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, a kind of filter automatic dialing unit, comprise disc holder 1, disc holder 1 is provided with disk 2, periphery at disk 2 is evenly distributed with several mounting holes 3, being located at the swing pinion 5 at disk middle part is connected by driving belt 9 with driven wheel 8 on the stepper motor 7, on disc holder 1, be fixed with magnetic induction sensor 12, on disk 2, be provided with magnet 10, magnetic induction sensor 12 is connected with control computer 14, and control computer 14 is connected with stepper motor 7 by motor driver 13.In the mounting hole from the inside to surface, it is different that thickness is installed, and according to the tactic filter combination of lead, tin, copper, aluminium, combined situation and thickness are iso standard and recommend, filter is installed in the mounting hole of reserving on the disk, compresses filter with hold-down ring.Described several mounting holes that are evenly distributed on disc circumference have 40, comprise that successively 1 conduct determines the hole, room of initial position, 1 as preformed hole, 10 holes corresponding respectively the filter of 10 kinds of standard low-to-medium altitude gas kerma rate series, 13 holes corresponding respectively the filters of 13 kinds narrow pedigree row, 7 holes corresponding respectively the filter of 7 kinds of wide range series, 8 holes corresponding respectively the filter of 8 kinds of high kerma rate series.Computer-controlled stepper motor by gear drive, drives the disk rotation, reaches the purpose of selecting different filters.In experiment, elder generation's rotating circular disk, seek initial position, when magnetic induction sensor detects the magnet position, send signal and give computing machine, the control disk stops operating, and this moment, the hole, room faced toward shutter, and the position in hole, room is an initial position, then according to the needed radiation field of experiment, correspond to the hole site number at disk place, input purpose hole site number, computing machine calculates purpose hole site number and present hole site gap automatically, with the rotation minimum stroke is purpose, the drive stepping motor that uses a computer forward or reverse is to desired location, and the filter of needs is loaded into soon in front of the door, generates the radiation field that needs.10 filters with low air kerma rate series are given an example, and the combined situation of lead, tin, copper, aluminium and filter gross thickness are as follows:
As shown in Figure 2, described each mounting hole is the hole that anterior diameter is big, the rear portion diameter is little, is provided with the step that is used to install filter in the mounting hole, compresses filter by hold-down ring 4.The structure of hold-down ring as shown in Figure 3.
In x-ray bombardment amount (protection level) standard set-up, use this filter automatic dialing unit, add other automatic control and supervisory system, operating personnel by computing machine, just can realize the Automatic Control of x-ray bombardment amount (protection level) standard set-up between control.
Device described in the utility model is not limited to the described embodiment of embodiment, so long as those skilled in the art draw other embodiment according to the utility model scheme, belongs to the scope of technological innovation of the present utility model and protection equally.
