As shown in fig. 5, 7 and 8, when the concentrated sulfuric acid solution seeps out of the first housing 200, a small amount of the concentrated sulfuric acid solution contacts with water, a large amount of heat is released during dilution of the concentrated sulfuric acid solution, after the wrapped paraffin 212 beside the seeped portion of the concentrated sulfuric acid solution is melted at a high temperature, the built-in effervescent tablet 213 sealed inside the wrapped paraffin 212 contacts with water and releases carbon dioxide gas, the internal pressure of the water cavity 410 becomes large, when the internal pressure of the water cavity 410 exceeds the set value of the pressure limiting valve 421, the pressure limiting valve 421 is opened, so that carbon dioxide or water in the water cavity 410 enters into the outer capsule 422, and the outer capsule 422 expands in a direction away from the second housing 400, thereby playing a role of warning.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
by adding the wrapping paraffin 212 wrapping the built-in effervescent tablet 213, when the concentrated sulfuric acid solution seeps out, the wrapping paraffin 212 contacts with water and releases a large amount of heat, so that the built-in effervescent tablet 213 contacts with water to generate a large amount of gas after the wrapping paraffin 212 is dissolved, and the outer capsule 422 plays a role in marking and alarming after being pressed and expanded; the process of generating gas after the built-in effervescent tablet 213 contacts with water plays a certain stirring role on the water, so that the concentrated sulfuric acid solution is diluted more fully and rapidly; the built-in effervescent tablet 213 releases gas, so that the internal pressure of the device is increased, and if the storage tube 110 is damaged, the concentrated sulfuric acid solution can be better extruded into the storage tube 110; the plurality of outer bladders 422 can play a role in shock absorption and protection after being inflated.
Example III
When the concentrated sulfuric acid solution in the inactivation chamber 310 in the above embodiment seeps out of the first housing 200 or the damaged storage tube 110 breaks through the first housing 200, it is difficult for a worker to identify the leakage position of the concentrated sulfuric acid solution by the appearance of the device; the embodiment of the application is optimized to a certain extent on the basis of the embodiment.
As shown in fig. 9, the preservation device of the nail emulsion surgical biopsy sample of the present application further includes a tubular film 500; the number of the paraffin components 210 is the same as that of the warning components 420, and the paraffin components and the warning components are in one-to-one correspondence; the number of the tubular membranes 500 is the same as that of the paraffin components 210 and the tubular membranes are in one-to-one correspondence with the paraffin components; the tubular membrane 500 is integrally in a circular tube shape, and the tubular membrane 500 is fixed between the outer wall of the first shell 200 and the inner wall of the second shell 400; the paraffin components 210 are positioned in the corresponding tubular membranes 500, and one end of the tubular membrane 500 far away from the first shell 200 is sleeved outside the pressure limiting valve 421 in the corresponding warning component 420, so that the tubular membrane 500 plays a role in isolation; the inside of the tubular membrane 500 is filled with water.
Preferably, the tubular membrane 500 is made of fluororubber.
As shown in fig. 10, after the wrapped paraffin 212 in the paraffin assembly 210 is melted, the built-in effervescent tablet 213 releases gas when meeting water, and the outer capsule 422 in the warning assembly 420 is correspondingly expanded under pressure, so that the exudation position of the concentrated sulfuric acid solution can be marked; the built-in effervescent tablet 213 reacts with water, so that the outer capsule 422 expands and vibrates, and can play a certain role in stirring water, thereby being beneficial to the dilution process of the exuded concentrated sulfuric acid solution.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
the paraffin components 210 are in one-to-one correspondence with the warning components 420 and are communicated through the tubular membrane 500, so that the paraffin components 210 are separated from water outside the tubular membrane 500, the built-in effervescent tablets 213 cannot contact with the water outside the tubular membrane 500, and the phenomenon that concentrated sulfuric acid solution exudes more seriously due to too severe reaction of the built-in effervescent tablets 213 in water is prevented; after the wrapped paraffin 212 in the paraffin assembly 210 is melted, the outer bag 422 in the corresponding warning assembly 420 is inflated, so that the approximate position of exudation of the concentrated sulfuric acid solution can be displayed; the built-in effervescent tablet 213 reacts with water to vibrate the outer capsule 422, thereby playing a certain role in stirring water and accelerating dilution of exuded concentrated sulfuric acid.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
