Description

Title of the invention: storage element for electrical equipment

[0001] The technical context of the present invention is that of fire safety devices, and in particular those dedicated to electrical equipment operating with a lithium-ion type electric battery. More particularly, the invention relates to a storage element of such electrical equipment.

[0002] In the state of the art, the use of electrical equipment equipped with a lithium-ion electric battery is known in order to have a long operating autonomy. Unfortunately, electrical risks exist with such electrical equipment, and in the event of a short circuit, damage to the electric battery or even deterioration thereof, the risk of fire is very high. In particular, such lithium-ion electric batteries store such a quantity of energy that any fires that break out - for example in the event of thermal runaway - are then very difficult to control.

[0003] To this end, fire safety rules and standards are becoming increasingly restrictive for manufacturers of such electrical equipment.

[0004] More particularly, the transport or storage of such electrical equipment, such as for example in the maritime or aviation field, can be a source of concern, since the risks of fire in such circumstances can take on even more serious proportions.

[0005] The present invention addresses this fire safety issue in order to propose a new storage element for electrical equipment equipped with an electric battery in order to respond at least in large part to the preceding problems and to further lead to other advantages.

[0006] Another object of the invention is to reduce the spread of a fire occurring on electrical equipment.

[0007] Another aim of the invention is to emit an alert signal as quickly as possible in the event of detection of a fire.

[0008] Another object of the invention is to provide such a storage element which is easy to use and compatible with numerous fields of application.

[0009] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a storage element for electrical equipment equipped with an electric battery, the storage element comprising a housing delimiting a housing for the electrical equipment and a closing cover coupled in an articulated manner to the housing, the closing cover being configured to be able to close the housing, the housing and / or the closing cover being formed of at least one wall comprising:

[0010] - an outer face comprising fiberglass;

[0011] - an inner face comprising carbon fiber;

[0012] - a flame retardant material located between the outer face and the inner face.

[0013] In the context of the present invention, the housing delimits a housing whose dimensions and shapes can be arbitrary. Preferably, the housing delimits a rectangular-shaped housing. In particular, the housing has sufficient dimensions to allow the insertion of electrical equipment such as a diving scooter or a drone. Generally, a length of the housing is between 350 cm and 1250 cm, a width of the housing is between 250 cm and 525 cm, and a height of the housing is between 200 cm and 510 cm. According to a first exemplary embodiment, the housing has a length of 350 cm, a width of 250 cm and a height of 200 cm. According to a second exemplary embodiment, the housing has a length of 600 cm, a width of 450 cm and a height of 450 cm. According to a third embodiment, the housing has a length of 1250 cm, a width of 525 cm and a height of 510 cm.

[0014] In the context of the present invention, the closing cover allows either access to the housing or closing the housing, preferably in a sealed manner. The closing cover is advantageously connected to the housing by means of a hinge allowing the cover to pivot between an open configuration in which the housing is accessible from an access area and a closed configuration in which the closing cover bears against the housing and completely closes the housing and the access area. The hinge is preferably of the steel hinge type, for example a steel alloy of type 316 and / or 304.

[0015] In the context of the present invention, the notion of sealing is considered as sealing to a gaseous fluid and for pressures of the order of atmospheric pressure.

[0016] In the context of the present invention, the housing is delimited by a wall that extends peripherally to said housing. Similarly, the closure lid is delimited by the same wall that has a complementary shape to that of the housing. In the context of the present invention, the walls delimiting the housing and / or the closure lid have a sandwich structure, in which the fireproof material is sandwiched between the outer face and the inner face of said walls. Preferably, all the walls delimiting the closure lid and / or all the walls delimiting the housing have an outer face comprising glass fiber, an inner face comprising carbon fiber and the fireproof material between said inner face and said outer face.

[0017] In the context of the present invention, the inner face is located on the side of the housing, that is to say the inside of the case or the closing cover. Conversely, the outer face is located on the side of a part outside the housing. The outer face extends parallel to the inner face of a given wall. Of course, in the context of the present invention, the case comprises several walls assembled with respect to each other in order to delimit the housing. Similarly, the closing cover comprises several walls assembled with respect to each other in order to delimit and / or close the housing.

[0018] In the context of the present invention, the fireproof material is a material that has been treated or designed so as to be made incombustible or less flammable. The fireproof material is located between the inner face and the outer face of a given wall. Preferably, the fireproof material fills the space located between the outer face and the inner face of a given wall.

[0019] Thus, the storage element according to the first aspect of the invention makes it possible to have and store in its housing electrical equipment equipped with an electric battery. The design of the storage element makes it possible to reduce fire risks since the electrical equipment is then confined in the housing, and the construction of the walls delimiting the housing are such as to limit the spread of a fire which would break out in the housing, so as to make it possible to alert users who may be able to intervene as quickly as possible.

[0020] Finally, the storage element according to the first aspect of the invention is easy to use and compatible with numerous fields of application, and in particular those of maritime or air transport, or even the use of such a storage element on a pleasure boat.

[0021] Indeed, according to a particularly preferred field of application of the invention, the storage element according to the first aspect of the invention is intended to allow a drone or a diving scooter equipped with an electric battery - for example of the lithium-ion type - to be stored in the housing. In addition, the storage element according to the first aspect of the invention is intended to allow containers containing flammable liquids, such as for example petrol tanks, to be stored in the housing. Thus, the storage of this electrical equipment or these flammable fluids is made safer and reduces the risk of fire.
