Abstract
The utility model relates to a fire proof structure for a tram. The utility model comprises an iron frame and a dust-proof cover 2, and a heat-radiating ventilation cavity 3 is arranged at an installing surface of the bottom of the iron frame 1. The iron frame 1 is installed at a tram top 7 by an upper molding element 4, a lower molding element 4 and a core-penetrating screw 6. An iron-made bracket 8 which is used for installing an electric appliance is arranged on the iron frame 1. When the utility model is adopted, the traditional mode that the load-bearing wood stand is utilized to realize supporting function is changed to use the iron frame to realize the supporting function; thus, the occupation space of the supporting member is decreased, and the heat-radiating space is increased; thereby, the fire alarm which is caused by the accumulation of the current heat or the climate heat can be reduced, and the reliability of the tram can be improved.
Description
The utility model relates to field of traffic facilities, is specifically related to the safety apparatus of traffic facilities, more particularly, relates to a kind of electric car fire alarm that is used to avoid or reduces electric car generation fire alarm and prevents and treats structure.
The connecting wire of electrical equipment equipment room is a copper conductor on the existing electric car, and the exposed part of copper conductor is easy to generate aerugo in use, and thickeies as time passes.Also may in the short time, produce very thick aerugo owing to bad contact.Aerugo has higher resistance.When electric current passed through, the part current transitions became heat energy, and electric current could pass through smoothly.End temperature can reach 200-300 degree centigrade.After temperature progressively raises, can follow the string by the plastic foreskin (comprising other combustible substances) of temperatures involved, progressively aging.Reach the degree that becomes fragile at last.Under the ignition action of the power spark of switch, produce burning, fire alarm appears.Can on existing structure, increase the brute spring ring and note to check remove and change the more parts of aerugo and prevent loosening and produce thicker aerugo and stop hi-heat generation, and then eliminate fire alarm.
The purpose of this utility model is to provide a kind of electric car fire alarm to prevent and treat structure, this electric car fire alarm prevents and treats structure can be by the improvement of structure, reduce because electrical equipment and the overheated local temperature that raises of connecting wire thereof by increasing to ventilate, make this temperature can not reach burning-point, thereby avoid and reduce the generation of fire alarm to greatest extent.
The purpose of this utility model is to realize like this, constructing a kind of electric car fire alarm prevents and treats structure and comprises brandreth, dust boot, it highly is 20 centimetres or higher vented cavity that the bottom attachment face of described brandreth is provided with, described brandreth on electric car pushes up, also is provided with the iron support that is used to install electrical equipment by last plastic and following plastic insulating mounting on described brandreth.
Implement electric car fire alarm of the present utility model and prevent and treat structure, can significantly reduce the fire alarm that produces of gathering, improve the safety and the reliability of electric car owing to electrical current heat or weather heat.
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:
Fig. 1 is the structure front view that electric car fire alarm of the present utility model prevents and treats structure.
Fig. 2 is the texture edge view that electric car fire alarm of the present utility model prevents and treats structure.
As depicted in figs. 1 and 2, electric car fire alarm of the present utility model prevents and treats structure and comprises brandreth 1, dust boot 2, it highly is 20 centimetres or higher heat dissipation ventilation chamber 3 that the bottom attachment face of described brandreth 1 is provided with, described brandreth 1 pushes up on 7 at electric car by last plastic 4 and following plastic 5 and adapter lug 6 insulating mounting, on described brandreth 1, also be provided with the iron support 8 that is used to install electrical equipment, place the electric car electric equipment at support.Owing to change traditional load-bearing flitch supporting for the retort stand supporting, reduced supporting member and taken up space, increased heat-dissipating space, and yoke has long-pending heat burning and weakness, and brandreth there are heat radiation and incombustible characteristics; Simultaneously, by making the electric insulating of brandreth and support and electric car roof, improved electrical security.By the cavity of brandreth bottom is set, the gap of raise brandreth and roof has been eliminated long-pending thermosphere and has been made it to become the heat dissipation ventilation device again.
Claims (1)
