Detailed description of the invention
In radium radon analyser, location and force feedback design are most important to the reliable of instrumentation and comfortableness.Conventional analogous instrument uses spring marble coordinate location dimples to realize, but this mechanism is sliding friction, the most laborious when varying.Using the elastomeric element fit circular arc connected in star equipped with running roller in the present invention, during rotation, frictional resistance is rolling friction, so that operation is the lightest；And location is realized when running roller rolls into arc groove, force feedback is substantially and location is reliable.And in existing analogous instrument; for making the rotating part portion of being relatively fixed rotate freely; gap would generally be provided with between rotating part and fixed part; but multiple sample detection scintillation chambers are installed on rotating part simultaneously; the light that non-detection scintillation chamber is sent may arrive detector by gap reflection, affects certainty of measurement；When taking off certain non-detection scintillation chamber, sunlight or light can arrive detector through gap reflection equally, and probe produces greatly damage.To this end, scintillation chamber's bore is carried out mutually isolated by the present invention, carry out anti-tampering design, addition shading pad parts, effectively reach the purpose of shading.
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
The present embodiment provides a kind of radium radon analyser, as shown in Figure 1, 2, 3, including detector assembly 9 and scintillation chamber 8；Described scintillation chamber 8 is multiple, and the present embodiment is three.
Three described scintillation chambers 8 are arranged in mounting assembly；Described mounting assembly includes fixed part and the rotating part that can rotate relative to fixed part, and three described scintillation chambers are installed on described rotating part.
Described fixed part includes quiet dish 3, and described rotating part includes rotating disk 5 and rotating disk guard ring 4,

In the present embodiment, as shown in Figure 4,5, 6, described running roller elastic force unit is one, is arranged on described quiet dish 3, and described groove 100 is three, be arranged on described rotating disk guard ring 4 and with three described scintillation chamber 8 one_to_one corresponding.
Described running roller elastic force unit also includes the slide 105 being fixed on described quiet dish 3, and it is positioned at slide 105 sliding pin 103 that can slide at described slide, described running roller 101 is arranged on the front end of described sliding pin 103 by rolling axle 102, described spring 104 is arranged at the rear end of described sliding pin 103, and its two ends are respectively against described sliding pin 103 and slide 105.101 1 radially outer power of described running roller given by described spring 104, make the trend that the oriented radial outside of running roller 101 moves, when rotating disk 5 together rotates with rotating disk guard ring 4, running roller 101 withstands on the medial wall of described rotating disk guard ring 4 and rolls, during until the described groove 100 of the arc being positioned on rotating disk guard ring 4 moves to running roller 101 position, running roller 101 enters described groove 100 under the action of the spring, completing location and force feedback, now corresponding with this groove 100 scintillation chamber 8 is positioned at directly over detector assembly 9.When described rotating disk 5 is together rotated further with rotating disk guard ring 4, described running roller 101 rolls out in this groove 100, until next groove 100 moves to described running roller 101, completes the location of next scintillation chamber 8.
Certainly, the present embodiment is provided solely for a kind of location and the installation of force feedback mechanism and structural representation.Described location and force feedback mechanism can also use groove to be arranged at fixed part, running roller elastic force unit is arranged at the mode of rotating part；A groove, the mode of multiple running roller elastic force unit can also be used.It is of course also possible to arrange multiple groove and multiple running roller elastic force unit to realize the setting of multiple anchor point, as long as those skilled in the art are according to the actual needs, all can deform in the technology of the present embodiment.
As shown in Fig. 3,7,8, upper surface at described quiet dish 3, it is positioned at the position directly over described detector assembly 9, and when when multiple described scintillation chambers 8, one of them is positioned at directly over described detector assembly 9, position directly below in remaining scintillation chamber 8, being provided with the shading pad 11 of annular, the downside of described shading pad 11 is provided with flat spring 12.The depressed part 13 for placing described flat spring 12 and shading pad 11 is offered in the upper surface of described quiet dish 3.
Setting by shading pad, it is possible to avoid scintillation chamber's light interference, ensure that the shading pad compression to rotating disk by flat spring, also do not interfere with the rotation of rotating disk simultaneously.
Above described rotating part, axis being provided with central shaft 6, described central shaft 6 is provided with three hold assemblies 7, the position that described hold assembly 7 and described rotating part are installed described scintillation chamber 8 is oppositely arranged, and is used for clamping described scintillation chamber.
Being positioned at axial location in the lower section of described quiet dish 3 and be provided with bearing block 2, the lower section of described bearing block 2 is provided with mounting seat 1, and described quiet dish 3, bearing block 2 fix with mounting seat 1.Described central shaft 6 is arranged in described bearing block 2.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or variation still in the protection domain of the invention among.
