Specific embodiment
Below in conjunction with drawings and Examples, the technical scheme in the present invention is clearly and completely described.
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of waste barrel surface dose rate detection means, including rotating mechanism,
Side detector movement mechanism, top detector motion mechanism and its corresponding fault reset device and support.
The rotating mechanism is by motor 5, reduction box 4, turntable, pivoting support 1 and support 2, wherein motor 5 and reduction box 4
Composition driving means, pivoting support 1 are located at the lower section of turntable, and both gears are engaged；The detector 3 being fixed on support is used for surveying
Amount waste bucket bottom close rate level, pivoting support 1 are provided with guide plate 7 and alignment pin 6；Pail for used dressings is from top to bottom put into turntable
During, after being first directed to 7 Primary Location of plate, continue to be accurately positioned by 3 alignment pins 6 when declining again, it is ensured that pail for used dressings
Turntable central authorities are put in accurately.
Side detector movement mechanism is divided into motor 16, screw mandrel and guide rail 18, sliding plate 19 and support 20；It is fixed on sliding plate 19
Have for measuring pail for used dressings side close rate level detector 3, sliding plate 19 is arranged on guide rail and is connected with motor by screw mandrel, with
Realize the movable purpose of detector.The fault reset device of the motion is made up of rotating shaft 8 and spring 17, the guide rail
It is fixed on support, support one end is set in rotating shaft 8, the support other end is connected with spring 17；In mechanism malfunction, detection
When device cannot withdraw, detector 8 can be swung around the shaft, occur to contact firmly with detector, damage during preventing pail for used dressings from lifting by crane
Hinder detector；When spring 17 is to ensure normally to use, detector is located at correct position.
Top detector motion mechanism is divided into motor 12, reduction box 10, pivoted arm 11, electromagnetic clutch 9, steel wire 13, pulley
14 and the spring that is placed in spring protecting jacket 15.It is fixed with the pivoted arm 11 for measuring close rate level at the top of pail for used dressings

It is illustrated in figure 3 the schematic diagram that this waste barrel surface dose rate detection means uses example, waste in this schematic diagram
Bucket 21 is in working position, and each detector is measuring waste barrel surface dose rate level.Its workflow is as follows：Pail for used dressings is by upper
Turntable → side detector movement mechanism is put into lower lifting drives detector to be moved to working position by rest position so as near useless
Thing barrel side surface → top detector motion mechanism drives detector to turn to working position by rest position so as near pail for used dressings top
After portion surface → start measurement → measurement process terminates, top detector motion mechanism drives detector to be turned to not by working position
Breath position so as to drive detector to be moved to rest by working position away from pail for used dressings top surface → side detector movement mechanism
Position so as to hung away → end-of-job away from pail for used dressings side surface → pail for used dressings.
The content not being described in detail in this specification, belongs to prior art known to those skilled in the art.
