Description
Technical Field
The utility model relates to a rubbish field of retrieving especially relates to a take dustbin of automatic fire extinguishing function.
Background
The public garbage can is an indispensable public facility in public places such as banks, airports, hotels, roads and the like, and is a close social and sanitary environment. However, the existing public trash can still has a great potential safety hazard, people cannot pay attention to throwing inflammable articles such as cigarette ends into the trash can, or some accidents cause flames in the trash can, fire disasters are easy to cause in public places, and if the inflammable articles are not disposed in time, disasters are likely to happen, and huge life and property losses are caused. In view of the above-mentioned factors, a trash can with a fire extinguishing apparatus has been developed to better secure life and property safety.
The dustbin of taking extinguishing device in the existing market, its mode of putting out a fire mainly has three kinds: the first is that the dry powder fire extinguisher is placed in the box body, and the dry powder fire extinguisher is automatically opened to extinguish fire when a fire disaster happens; the second is to use a water pipe to connect a water pool, and automatically open a faucet to extinguish a fire when a fire disaster happens; the third is to combine the two modes, when a fire breaks out, the dry powder fire extinguisher is automatically opened to extinguish the fire, and then the water tap is automatically opened to extinguish the fire. The above three fire extinguishing modes can theoretically meet the fire extinguishing requirement to a certain extent, but have the following disadvantages: the fire extinguishing range cannot be fully covered. As is known, the dustbin has small effective space and limited preparation amount of fire extinguishing materials, and if one-time fire extinguishing fails, part of fire seedlings can not be extinguished in time to cause secondary fire.

In order to make the movable top plate 6 drop smoothly, the movable top plate 6 is smaller than the transverse cross section in the box body, so that the movable top plate 6 cannot be guaranteed to be sealed with the side wall of the box body. In the technical scheme, the bearing plate 4 is in sealing fit with the movable top plate 6 so as to ensure that a closed cavity is formed. The support plate 4 is preferably an encapsulated plate. In a further preferred scheme, one end of the supporting plate 4 is hinged on the inner side wall of the box body 1, and the movable end of the supporting plate 4 is connected on the inner side wall of the box body 1 through an electric control hook 5. The controller 9 is connected with the electric control hook 5 in a control way, and when the movable end of the supporting plate 4 is separated from the electric control hook 5, the movable end of the supporting plate 4 is turned over to enable the supporting plate 4 to be horizontally arranged. In this solution, the support plate 4 is not always horizontally arranged, but is triggered by the controller 9 in the event of a fire. Therefore, the phenomenon that garbage or foreign matters are accumulated on the supporting plate 4 in daily use and influence on the sealing fit between the supporting plate 4 and the movable top plate 6 in case of fire can be avoided.
Above-mentioned technical scheme relates to a dustbin of area automatic fire extinguishing function, this dustbin embeds has fire extinguishing systems, wherein including smoke sensor 8 in the fire extinguishing systems, controller 9 and activity roof 6, detect feedback controller 9 behind the smoke signal when smoke sensor 8, controller 9 triggers activity roof 6 motion, make activity roof 6 fall to interior bucket 3 top, with interior bucket 3 inside covering completely, make the regional vacuum state of an approximation of formation of whole area of starting a fire, whole area of starting a fire is kept apart with the air completely, reach the fire extinguishing effect.
On the basis of the technical scheme, a more preferable scheme is to combine the dry powder extinguishing function.
Specifically, the inside of box 1 is equipped with fire extinguishing ball 11, fire extinguishing ball 11 can explode the fire extinguishing powder when contacting the naked light. As shown in the figure, the lower end face of the movable top plate 6 is provided with a groove for accommodating a fire extinguishing ball 11, and the fire extinguishing ball 11 is arranged in the groove. The lower end face of the movable top plate 6 is connected with a fire extinguishing ball support 13, one end of the fire extinguishing ball support 13 is hinged to the movable top plate 6, and the other end of the fire extinguishing ball support 13 is connected with an electric control lock 10 on the movable top plate 6. The fire extinguishing ball support 13 is used for arranging the fire extinguishing ball 11 in the groove. The controller 9 can open the electrically controlled lock 10 based on the smoke sensor 8 signal.
In the above scheme, on the basis that the movable top plate 6 falls to form the closed cavity, the fire extinguishing ball 11 is further arranged, and when the fire extinguishing ball 11 is in contact with open fire, dry powder can be burst to extinguish the fire. The fire extinguishing ball 11 is arranged on the movable top plate 6, and the dustbin with two fire extinguishing modes is used for extinguishing fire according to the following steps.
(1) The smoke sensor 8 gives out an early warning signal to the controller 9, the controller 9 controls the electric control lock 10 to be opened, the fire extinguishing ball 11 falls off, and the fire extinguishing ball is automatically exploded to extinguish fire for the first time when meeting open fire, so that the fire is extinguished as far as possible.
(2) The controller 9 controls the electric control hook 5 to open, so that the rubber-coated plate is pressed from a vertical state to a horizontal state. Then, the controller 9 controls the movable top plate 6 to fall down along the slide rails 12 of the movable top plate 6 to cover the garbage can. Therefore, the whole ignition area forms an approximate vacuum state, so that the ignition area is fully covered, the flame can be completely extinguished finally, and secondary ignition is effectively prevented.
As is known, combustion must be subject to three conditions: firstly, there is combustible, secondly, the combustible reaches the ignition point, and thirdly, the combustible contacts with oxygen (air). On the one hand, the dustbin and the suspended ceiling are made of metal objects and are non-combustible objects, and on the other hand, the whole fire area is completely isolated from air, so that oxygen in the fire area is exhausted. In conclusion, because the dustbin of taking this device can carry out the full coverage to the region of starting a fire, can put out the flame totally finally, the effectual emergence that prevents the secondary and start a fire.
In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Although embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the principles and spirit of the present invention.
