Abstract
This utility model relates to Nuclear Instrument technical field, is specifically related to a kind of Nuclear Instrument photomultiplier tube damping device.It interior dielectric isolation layer including being surrounded on the outer surface of photomultiplier tube, the outside cladding of described interior dielectric isolation layer is provided with elastic shock attenuation layer, and the outside of described elastic shock attenuation layer is provided with external insulation fixed layer.This utility model is possible not only to play photomultiplier tube the protective effect of physics damping, it is possible to is prevented effectively from photomultiplier tube and collides with metal shell and damage, but also is prevented from high-voltage breakdown, is beneficial to improve the service life of instrument.
Description
Technical field
This utility model relates to Nuclear Instrument technical field, is specifically related to a kind of Nuclear Instrument photomultiplier tube damping device.
Background technology
In the installation that Nuclear Instrument (such as densimeter detector) is conventional connects, photomultiplier tube is to be directly placed into metal shell
In, certain space can be there is between itself and metal shell, cause always there will be vibrations in the use at transport or scene,
Thus easily make photomultiplier tube and metal shell collide then and damage, be unfavorable for stable detection, reduce service life.
For above-mentioned situation, it is necessary to prior art to be made improvement further.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure and designs simply, can be prevented effectively from photoelectricity times
Increase the Nuclear Instrument photomultiplier tube damping device that pipe collides with metal shell.
For realizing above-mentioned technical purpose, the technical scheme that this utility model employing is following:
Nuclear Instrument photomultiplier tube damping device, including the interior dielectric isolation layer of the outer surface being surrounded on photomultiplier tube,
The outside cladding of described interior dielectric isolation layer is provided with elastic shock attenuation layer, and it is solid that the outside of described elastic shock attenuation layer is provided with external insulation
Given layer.
As preferably, described interior dielectric isolation layer is the high pressure resistant adhesive tape of the outer surface being wound in photomultiplier tube.
As preferably, described elastic shock attenuation layer is elastic foam.
As preferably, described external insulation fixed layer is the high pressure resistant adhesive tape of the outer surface being wound in described elastic shock attenuation layer.
This utility model compared with prior art has the following beneficial effect:
After the outside of photomultiplier tube first uses high pressure resistant adhesive tape to isolate, then increase by one layer on high pressure resistant adhesive tape
Elastic foam, then be fixed with high pressure resistant adhesive tape, the protection being so possible not only to play photomultiplier tube physics damping is made
With, it is possible to it is prevented effectively from photomultiplier tube and collides with metal shell and damage, use high pressure resistant adhesive tape can also prevent height
Pressure punctures, and is beneficial to extend the service life of instrument.
Accompanying drawing explanation
The following drawings is only intended to, in schematically illustrating this utility model and explaining, not limit model of the present utility model
Enclose.Wherein:
Fig. 1 is the cross-sectional view of this utility model embodiment；
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: 1-photomultiplier tube；Dielectric isolation layer in 2-；3-elastic shock attenuation layer；4-external insulation fixed layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible
Recognize, in the case of without departing from spirit and scope of the present utility model, can be by various different modes to described
Embodiment is modified.Therefore, accompanying drawing and description are inherently protection that is the most illustrative rather than that be used for limiting claim
Scope.
As depicted in figs. 1 and 2, Nuclear Instrument photomultiplier tube damping device, including the outer surface being surrounded on photomultiplier tube 1
Interior dielectric isolation layer 2, described interior dielectric isolation layer 2 outside cladding be provided with elastic shock attenuation layer 3, described elastic shock attenuation layer 3
Outside be provided with external insulation fixed layer 4.
Wherein, described interior dielectric isolation layer 2 is preferably used high pressure resistant adhesive tape, is wound around easy to use, by high pressure resistant adhesive tape
It is dielectrically separated from, places the high pressure impact on material.
Described elastic shock attenuation layer 3 is preferably with elastic foam, with low cost, photomultiplier tube 1 can be played physics and subtract
The protective effect of shake, it is possible to be prevented effectively from photomultiplier tube 1 and collide with metal shell and damage.
It addition, described external insulation fixed layer 2 is it is also preferred that use high pressure resistant adhesive tape, not only it is fastened conveniently, additionally it is possible to anti-
Only high-voltage breakdown, improves instrument safety, stability.
With reference to Fig. 1, after the outside of photomultiplier tube 1 first uses high pressure resistant adhesive tape to isolate, then at high pressure resistant adhesive tape
One layer of elastic foam of upper increase, is finally fixed with high pressure resistant adhesive tape, is so possible not only to play the effect of damping, additionally it is possible to
Prevent high-voltage breakdown, it is possible to effectively extend instrument service life.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to model of the present utility model
Enclose.Any those skilled in the art, equivalent done on the premise of without departing from design of the present utility model and principle
Change and amendment, all should belong to the scope of this utility model protection.
