Abstract
The utility model relates to equipment antiseptic device which can be widely applied to corrosion prevention for all kinds of equipment in a protective housing, and comprises a protective housing (1), equipment (3), a gas displacement device (4) and other parts. For the antiseptic device, the protective housing (1) is internally installed with the gas displacement device (4) for displacing corrosive gases generated in the protective housing (1) due to self degradation, environmental factors, high frequency radiation and the like of a subspace (2) and the equipment (3), thus avoiding or reducing corrosion of the subspace (2) and the equipment (3) in the protective housing (1), and further improving the service life and reliability of the subspace (2) and the equipment (3).
Description
Technical field
The utility model relates to a kind of equipment anticorrosion device, can be widely used in the anticorrosion of all kinds of protection box equipments.
Background technology
Existing equipment when mounted, be waterproof and dustproof when installing especially in the open air, prevent the corrosion of corrosive goods confrontation equipment in the external environment, prevent that purpose such as outside electromagnetic interference from carrying out protective treatment, promptly equipment is installed in the protective housing this protective housing and extraneous no obvious convection current.
And the protection box equipment is behind long-play, because the high frequency electromagnetic radiation that is produced during the equipment self operation, halide that the degraded of circuit board in the equipment and other accessories produces and organic compound etc. cause local corrosion to assemblies such as the metal of electrical equipment or electrical equipment, plastics, PCB, thereby cause the problems such as fault, reduction in service life, reliability decrease of electrical equipment.
The utility model content
The problem that the corrosive gas that is subjected to produce in the protective housing for the service life that solves existing protection box equipment and reliability etc. influences, the technical solution of the utility model is: by the gas displacement mode corrosive gas in the protective housing is replaced, thereby inhibition or corrosion mitigation gas are to the corrosion of protection box equipment, and its step is divided into:
1. determine the startup of gas displacement and close condition;
Start gas displacement when 2. satisfying entry condition;
3. satisfy and close gas displacement when closing condition.
The startup of gas displacement, the condition of closing can be the concentration values of corrosive gas, operation hours, calendar date, external environmental condition or protective housing related side's requirement condition etc.
The startup of gas displacement, the condition of closing can be the combinations of a plurality of conditions of single conditioned disjunction.
The gas of replacing with protective housing internal corrosion gas can be external environment gas, also can be that gas also can be the specific gas that is used to replace through the gas of processing such as purifying in external environment gas or the protective housing.The gas displacement mode can be the gas communication exchange, also can be gaseous transfer, also can be to vacuumize the back to replenish clean gas.
The utility model proposes equipment anticorrosion device in a kind of protective housing, it comprises protective housing 1, is installed in the equipment 3 in the protective housing, is installed in the protective housing or the parts such as gas displacement device 4 on the protective housing.Can comprise one or more subspaces 2 in the protective housing.Protective housing can be airtight, do not have obvious convection current with external environment.Can have between the subspace and be communicated with or independent closed.Can place one or more equipment in the subspace.The gas displacement device is the device that the corrosive gas that will protective housing be produced in 1 and substitution gas are replaced, and this installs the not safeguard function of tamper protection case itself.
This device is simple to operation, not only can improve the service life of protection box equipment, has also improved the reliability of protection box equipment to a certain extent.
Description of drawings
Below in conjunction with accompanying drawing 1 and embodiment the utility model is described further:
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a gas displacement device gas circuit schematic diagram.
The specific embodiment
As Fig. 1 is the enforcement structure of equipment anticorrosion method in a kind of protective housing, and it comprises protective housing 1, subspace 2, equipment 3, parts such as gas displacement device 4.Can comprise one or more subspaces 2 in the protective housing.Protective housing can be airtight, do not have obvious convection current with external environment.Can have between the subspace to be communicated with or independent closed, can place one or more equipment in the subspace.With the device that the corrosive gas that produced in the protective housing 1 and substitution gas are replaced, wherein gas displacement mode can be automatic or manual.Substitution gas can be an external environment gas, or in external environment gas or the protective housing gas through purifying the gas that waits processing, or the specific gas that is used to replace.
With the concentration value of corrosive gas is that startup, the condition of closing of replacement process is example, and the concrete steps of this anti-corrosion method are described:
During concrete operations, the sensor in the protective housing 1 can be measured in the protective housing 1 corrosive gas automatically and open air exchange system automatically and carry out gas displacement when reaching the predetermined concentration value as the concentration of (halogenation gas etc.).During gas displacement, external environment gas enters air inlet storehouse 6 through air inlet 5 by the scavenger pump driving and purifies through air inlet processing storehouse 7, enters protective housing 1 after the processing such as dehumidifying.In the protective housing 1 gas through pump-down process storehouse 10 purified treatment after exhaust storehouse 9 directly drain in the ambient atmosphere by exhaust outlet 8.When the detected gas concentration of sensor was lower than the particular concentration value, gas displacement device 4 was closed.Gas displacement device gas circuit schematic diagram as shown in Figure 2.
The above, only be in order to concrete case study on implementation of the present utility model to be described, but be not in order to limit practical range of the present utility model, such as those skilled in the art must be covered by the scope of the utility model claim not breaking away from all equivalence changes of being finished under indicated spirit of the utility model and the principle or modifying.
