In some embodiments of the invention, as shown in fig. 7, a barrier 405 extends around the rim of the opening of the cell body 4. Set up stopping part 405 through 4 top opening positions in cell body and can further prevent that the oil body of burning from leaking, the speed that the oil body of burning leaked can further be delayed in this kind of design, strives for the buffering time that the rescue was put out a fire.

In summary, embodiments of the present invention provide a flame retardant bracket for an oil reservoir and a system thereof;

in a first aspect, the present invention provides a flame-retardant support for an oil reservoir, including a housing 1 having an open bottom, a mesh member 3 installed in the housing 1, and flame-retardant particles 2 filled in the mesh member 3, wherein an oil discharge portion is provided at a top of the housing 1. The whole shell 1 can bear workers to walk; the burning oil body can flow into the shell 1 along an oil discharge hole at the top of the shell when flowing, and contacts with the flame-retardant particles 2 in the shell 1 to further realize fire insulation and flame retardance, and the oil body after fire extinguishment can continuously permeate and evacuate along the grid piece 3 at the bottom of the shell 1, the flame-retardant particles 2 in the device can replace natural stone cobblestones in the prior art, materials do not need to be obtained and long-distance transportation does not need, the cost brought by transportation capacity is greatly reduced, and the condition that the ecological environment is changed due to the large amount of mining of the goose warmer stones is avoided; the shape of the flame-retardant particles 2 is mostly prepared according to the industrial standard, the particle size is uniform, and gaps for oil to flow are formed between the adjacent flame-retardant particles 2, so that the design can ensure that the oil cannot be blocked in the shell 1, and the flame-retardant effect is reduced; meanwhile, the oil body can be ensured to continuously permeate and drain downwards, the cleaning and the maintenance are convenient, and the labor cost brought by the maintenance is greatly reduced; the device utilizes the grid member 3 in the shell 1 to fill the flame-retardant particles 2, and can ensure that the oil body after flame retardation is discharged along the mesh of the grid member 3; according to the invention, the oil unloading part at the top of the shell 1 is utilized to enable the burning oil body (or liquid) to flow rapidly and permeate downwards through the meshes of the grid piece 3, so that the oil body (or liquid) is not accumulated on the surface of the shell 1 or in a particle layer in the grid piece 3, when the oil body permeates into the flame-retardant particles 2 in the shell 1, the oil is rapidly permeated through gaps among the flame-retardant particles 2, and the flame-retardant particle 2 layer of the grid piece 3 in the cover plate 103 can play a certain flame-retardant and fire-insulating role; meanwhile, the device replaces the existing natural stone cobble flame-retardant material, the use cost of the whole device is greatly reduced, the practical value and the technical value are high, the social benefit and the economic benefit are obvious, and the device has the condition of large-scale popularization and use.

When in actual use, when the oil body of burning flows to casing 1 department, the oil body of burning can be followed oil discharge portion and get into inside casing 1 to with fire-retardant granule 2 contact, and then realize fire-retardant fire insulation, the oil body after putting out the fire can be followed the mesh outflow of net spare 3 and collected.

In a second aspect, the embodiment of the application provides an oil storage tank uses fire-retardant system, include a plurality of fire-retardant supports as above, still include cell body 4, install the support frame 401 that is used for erectting a plurality of fire-retardant supports in the cell body 4, have cavity 402 between support frame 401 and the 4 bottoms of cell body, row oil well 403 has been seted up to the 4 bottoms of cell body, fire-retardant layer has been laid to the 4 bottoms of cell body. The tank body 4 is an oil tank arranged on the periphery of the transformer; the support frame 401 is erected in the tank body 4, the flame-retardant support is fully paved at the top of the support frame 401, the support frame 401 can obviously improve the bearing capacity of the flame-retardant support, the flame-retardant support does not need other installation processes, only the flame-retardant support is placed at the top of the support frame 401, the period of field construction and laying is greatly shortened, the fully paved flame-retardant support can cover and seal the opening of the whole tank body 4, the design can ensure that the flame-retardant support in the path of the burning oil body can be subjected to primary fire extinguishing and then trickled into the tank body 4 for secondary fire extinguishing, the secondary fire extinguishing is realized by the flame-retardant layer paved at the bottom of the tank body 4, the burning oil body passing through the flame-retardant layer can be thoroughly extinguished and then discharged and collected through the oil discharge well 403, the fire extinguishing effect can be greatly improved by the design, and the occurrence of the re-burning situation of the oil body is avoided; the invention has the advantages of fire insulation, flame retardance, oil leakage, water seepage, skid resistance, easy maintenance and cleaning and stronger bearing capacity, and can effectively meet the requirements of installation, operation, maintenance, overhaul, safety and the like; when the transformer has a fault accident, the transformer is easy to explode due to combustion and the oil body leaks and burns, the oil body can irregularly leak and burn around, after fire-fighting equipment arranged around the transformer fails successively, along with the combustion of the transformer body and the continuous leakage of the burning transformer oil, continuous high-temperature oil pool fire or flowing fire overflowing out of the oil pool can be easily formed, and secondary disaster occurs, and certain difficulty is brought to fire rescue, the system realizes the functions of inflaming retarding, oil seepage and water seepage by utilizing the cooperation of the inflaming retarding support and the pool body 4, when the irregularly leaked oil body permeates the inflaming retarding support to the bottom of the pool body 4, if the oil body which is burnt with extremely low probability exists, the inflaming retarding layer laid at the bottom of the pool body 4 can realize secondary inflaming retarding in the pool body 4, the temperature of the integral cavity 402 at the bottom of the oil pool is reduced, and the oil body naturally flows into the oil discharge well 403, under the action of a double-layer fire extinguishing mechanism, the flow rate of oil bodies is greatly delayed, and a certain buffer time is strived for before fire rescue arrives, so that accidents are prevented from being further expanded, and the invention has higher safety protection performance.

In practical use, the burning oil body flows to the flame-retardant support, primary combustion extinguishing is realized through the flame-retardant support, the oil body which is not subjected to combustion extinguishing enters the pool body 4 to be accumulated, secondary combustion extinguishing is carried out through the flame-retardant layer, and the combusted oil body flows into the oil drainage well 403 to be collected.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
