According to the automatic sealing device, moisture in the electrical cabinet can be automatically sensed to automatically prevent moisture from entering and actively protect in time, the damage to the electrical equipment in the electrical cabinet can be avoided, and the electrical equipment in the electrical cabinet can normally and stably operate.
Description
Technical field
The present invention relates to a kind of electrical control cubicles automatic sealing device.
Background technology
In the electrical control cubicles various electric component can be installed; such as circuit breaker, contactor, automatic switch, push-button switch, indicator light, earth leakage protective device, and sophisticated equipment such as control instrument instrument of some other automation, frequency converter, mini air conditioner, communication apparatus, computer installation, PLC.
Electrical control cubicles is of many uses, all is able to a large amount of uses indoor, outdoor.In the abominable place of service condition, requirements such as that electrical control cubicles design has is dustproof, waterproof, in the hope of the electric equipment in the electrical control cubicles can be normally, stable, according to the useful life work that designs.
Existing electrical control cubicles does not have the function that prevents that automatically moisture from entering, and can only can not accomplish in time, automatically carry out waterproofing protection to electrical control cubicles protection and protection by manually coming.Along with wearing out of electrical control cubicles, and the breakage of electrical control cubicles inner waterproofing facility, these situations can make the moisture and the moisture of outside enter electrical control cubicles, cause the damage of the electric equipment in the electrical control cubicles, thereby bring tremendous loss and inconvenience for production and life.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of sealing device, and it can seal electrical control cubicles water inlet place when having moisture to enter electrical control cubicles automatically.
For this reason, the present invention has adopted following technical scheme: the electrical control cubicles automatic sealing device comprises: sensor unit, in order to detect the humidity in the electrical control cubicles; Signal processing unit is handled in order to the signal to transducer; Performance element, the response signal processing unit is in order to external output switching manipulation; The foamed glue device is filled in order to form sealing; Wherein, sensor unit is connected with signal processing unit, and the output of signal processing unit is connected with performance element, and performance element is serially connected in the foamed glue output pipe that is connected with the foamed glue device.
Optionally, described performance element is an electromagnetic valve.
Further, described performance element is the motorized motions valve.
The present invention has following good technique effect:
The present invention can detect the moisture that enters in the electrical control cubicles automatically, prevents that moisture from entering, and in time, protect on one's own initiative, avoids causing the damage of the electric equipment in the electrical control cubicles, guarantees that the electric equipment in the electrical control cubicles can be normally, stable operation.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing is the theory diagram of one embodiment of the invention.
Among the figure: 1, sensor unit, 2, signal processing unit, 3, performance element, 4, the foamed glue output pipe, 5, the foamed glue device, 6, shower nozzle.
Embodiment
Referring to accompanying drawing, the electrical control cubicles automatic sealing device comprises sensor unit 1, in order to detect the humidity in the electrical control cubicles; Signal processing unit 2 is handled in order to the signal to transducer; Performance element 3, response signal processing unit 2 is in order to external output switching manipulation.Wherein, sensor unit 1 is connected with signal processing unit 2, and the output of signal processing unit 2 is connected with performance element 3, and performance element 3 is serially connected in the foamed glue output pipe 4 that is connected with foamed glue device 5.
Sensor unit 1 generally is installed in opening part, the heat dissipation ventilation place of electrical control cubicles, when flooded condition occurring in the electrical control cubicles, the perceptual signal of 2 pairs of sensor units 1 of signal processing unit carries out determination processing, make the performance element 3 that is connected with signal processing unit 2 be in open mode, foamed glue in the foamed glue device 5 from water inlet place that shower nozzle 6 sprays in the electrical control cubicles, reaches the purpose of sealing by foamed glue output pipe 4, performance element 3.
Sensor unit 1 can adopt humidity sensor commonly used, also can place two probes opening part, the person of heat dissipation ventilation place of electrical control cubicles, by detecting two resistance change rates between the probe, determines what of the size of humidity and moisture.More than detect two probes of humidity, also can be placed on the place that the opening part, below, heat dissipation ventilation place of electrical control cubicles can ponding.
Foamed glue polyurethane foam (OCF) is the product of aerosol technology and polyurethane foam technology cross coupled.It is a kind of components such as base polyurethane prepolymer for use as, blowing agent, catalyst to be filled in special polyurethane products in the withstand voltage aerosol jar.When material sprayed from the aerosol jar, the polyurethane material of foam shape can expand rapidly and form foam with moisture generation curing reaction in air or the matrix that touches.OCF foam after the curing has multiple effects such as joint filling, bonding, sealing, heat insulation, sound-absorbing, be a kind of environmental protection and energy saving, construction material easy to use, applicable to sealing and plugging, fill a vacancy squeegee, fixing bonding, heat preservation and soundproof is particularly useful for sealing and plugging and waterproof between plastic-steel or aluminum alloy doors and windows and body of wall.
In order to reach desirable effect, for the place of water inlet and moisture easily such as the opening part of electrical control cubicles, heat dissipation ventilation place, be designed to structure of two layers, and its external perforate is smaller as far as possible, shower nozzle 6 is installed in the above-mentioned structure of two layers space, shower nozzle 6 can be designed to a plurality of branches shower nozzle, is installed in the different places in the above-mentioned structure of two layers space simultaneously, to accelerate the jet velocity of foamed glue, form sealant rapidly.
Optionally, described performance element is an electromagnetic valve.
Further, described performance element is the motorized motions valve.
In the application of reality, performance element 3 is installed for convenience, a valve can be set in the outlet of foamed glue device 5.
