Description
Technical field
The utility model relates to a kind of electric controller of boats and ships fire damper, belongs to a kind of induction controller of boats and ships fire damper.
Background technology
When occurring for preventing fire, enter the flame in air trunking, red-hot air-flow and smog and spread to the place do not caught fire from the place that catches fire, clean cross-sectional area should arrange fire damper more than the conduit of 0.075m2.SOLAS's (SOLAS pact) specifies, outside fire damper decapacitation is closed automatically, also manually must close from the both sides on bulkhead or deck.
It is generally that the temperature control closing device of 70 DEG C by carrying realizes that fire damper is closed automatically; Simple mechanical type closedown is difficult to the both sides met from bulkhead or deck and carries out artificial requirement of closing, therefore, artificial closedown adopts mechanical stay cord mode and electric remote control two kinds of modes to combine to realize usually, namely adopt mechanical stay cord to control shelves fire lock in the side on bulkhead or deck, at the opposite side on bulkhead or deck, a push button is set, start releasing device by remote control electric switch to control the power supply that fire damper closes electromagnet, realize the closedown of shelves fire lock.
This closedown mode also exists obvious drawback: need adopt machinery and Electronic control equipment simultaneously, and, for being provided with the large ship of multiple grades of fiery locks, adopt mechanical dragline type to control often because shelves fire lock is arranged comparatively discrete, cause closedown consuming time longer, cause potential safety hazard.
Utility model content
In order to overcome the deficiency that existing control device exists, the utility model provides a kind of electric control device, and being heated by liquid gas changes into gas and the volumetric expansion that occurs, and fire damper when breaking out of fire, can be closed automatically.
The utility model solves the technical scheme that its technical problem adopts:
An electric controller for boats and ships fire damper, comprises contact mechanism, heat-conducting mechanism, and described heat-conducting mechanism comprises expansion bucket; Wherein be provided with the slip cavity of a both-side opening in expansion bucket, described contact mechanism comprises two symmetries and is arranged on sliding shoe in slip cavity and the symmetrical contact making device being arranged on expansion bucket both sides, contact making device is arranged on the drive circuit of fire damper, sliding shoe adopts conductive material to make, contact making device is provided with positive pole and negative pole two connecting terminals, when slip cavity is heated, sliding shoe moves towards contact making device, connect positive pole and negative pole two connecting terminals, fire damper is closed.
As further innovation of the present utility model, the both sides of expansion bucket are provided with heat transmission fin.
As further innovation of the present utility model, in described slip cavity, be filled with nitrogen or liquid nitrogen.
As further innovation of the present utility model, be respectively provided with a rail brackets in described expansion bucket both sides, described rail brackets is provided with a sliding eye, be slidably connected between described sliding shoe outer wall and described sliding eye inwall.
As further innovation of the present utility model, in described sliding eye, be provided with needle bearing.
The beneficial effects of the utility model are:
1, the utility model is by an easy expanded by heating mechanism, when breaking out of fire, slip cavity is subject to thermal drivers sliding shoe make contact, compared to traditional automatically controlled and Mechanical course, the utility model automaticity is higher, and feedback is also more timely.
2, heat transmission fin of the present utility model can improve the heating surface area of slip cavity, improves the utility model to the sensitivity of the situations such as fire.
3, liquid nitrogen is drawn materials conveniently, and the more stable property of chemical property, long-term storage can not cause corrosion to slip cavity in slip cavity.
4, rail brackets can arrive sliding shoe and supports, and makes sliding shoe comparatively to contact mechanism, can improve the utility model stability by precise contact.
5, needle bearing has good radial support and axial lubricity, can improve the stability of sliding shoe when mobile further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model;
In figure: 1, expansion bucket; 2, sliding shoe; 3, contact making device; 4, heat pipe; 5, conducting strip; 6, liquid injection port; 7, rail brackets; 7a, sliding eye.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of electric controller of boats and ships fire damper, is located at airduct inside, comprises contact mechanism, heat-conducting mechanism, and described heat-conducting mechanism comprises expansion bucket 1; Wherein be provided with the slip cavity of a both-side opening in expansion bucket 1, described contact mechanism comprises two and symmetrical installs sliding shoe 2 in slip cavity and the symmetrical contact making device 3 being arranged on expansion bucket 1 both sides, contact making device 3 is arranged on the drive circuit of fire damper, sliding shoe 2 adopts conductive material to make, and contact making device 3 is provided with positive pole and negative pole two connecting terminals.
The both sides of expansion bucket 1 are provided with heat transmission fin, and heat transmission fin comprises the heat pipe 4 that some are embedded into expansion bucket 1 outer wall, and the positive and negative of heat pipe 4 is fixed with conducting strip 5;
Liquid nitrogen or nitrogen is filled with in described slip cavity, nitrogen expanded by heating or liquid nitrogen is utilized to be subject to the characteristic of thermal evaporation expansion, sliding shoe 2 is moved towards two ends, top is pressed on connecting terminal, positive pole and negative pole two connecting terminals are connected, positive pole and cathode contact connect the closed motor circuit of fire damper, fire damper is closed, expansion bucket 1 is also provided with the liquid injection port 6 for pouring into liquid nitrogen or nitrogen;
