Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Fig. 1-4 show an embodiment of the charging and replacing cabinet of the present invention, which is an immersed fire-fighting type charging and replacing cabinet. As shown in fig. 1, the battery charging and replacing cabinet comprises a cabinet body 9, two rows of partition openings 7 are arranged on the cabinet body 9, a fire-fighting chamber 13 is arranged at the upper part of the cabinet body 9, a rear cabinet door 16 is arranged at the rear part of the cabinet body 9, and an operation room is reserved between the rear cabinet door 16 and the rear wall of the partition opening 7.

Each partition 7 is divided into a bin opening 10 and a bin door 11, wherein seams inside the bin opening 10 are connected in a sealing mode, and in practice, complete sealing can be achieved through filling agents after welding seams. The sealing strip 12 is arranged on the inner side of the bin door 11, after the bin door 11 is locked, a gap between the bin door 11 and the bin opening 10 is in a sealed state, the lower part of the partition opening 7 is sealed, and the height of the sealing area exceeds the height of the battery pack 8 so as to meet the requirement of immersing the battery pack. The immersion system of the battery charging and replacing cabinet comprises a medicament bottle 1 positioned in a fire-fighting chamber 13, wherein in the embodiment, liquid contained in the medicament bottle is water, and in the embodiment, the interior of the medicament bottle is in a high-pressure state.

The medicament bottle 1 is provided with an infusion pipeline, and specifically comprises a main pipeline 2 connected with the mouth of the medicament bottle and branch pipelines 3 arranged on the main pipeline 2, wherein the mouths of the branch pipelines 3 extend into the inner tops of the partition ports 7, and nozzles 4 (shown in figure 4) are arranged at the mouths of the tail ends of the branch pipelines 3, and the nozzles 4 are temperature-sensitive glass nozzles. The battery package 8 is in the charging process, and normal conditions can produce certain heat, but when the battery package broke down (like burning or high temperature), the intraoral temperature in separate can continuously rise, adopts temperature sensing glass formula shower nozzle, can break immediately after the temperature reaches temperature sensing glass's the upper limit of bearing to start immersion system, immersion system starts the back, and the liquid in the medicament bottle 1 has flowed out till. Due to the adoption of a pure physical principle, the out-of-control condition cannot occur, the sensitivity is high, and the failure rate is low. After the temperature of the battery pack rises to the fragmentation temperature, the temperature sensing glass is broken, and the spray head 4 starts to spray water. Because the lower part of the partition 7 is in a sealed state, water is accumulated around the battery pack 8, and finally the battery pack 8 is immersed, so that the rapid cooling of the battery pack is realized.

In this embodiment, door 11 inboard is provided with sealing strip 12, closes door 11 after, and the lower part that separates mouth 7 is in airtight state, and after liquid got into and separates mouth 7, liquid can not separate the outflow of mouth 7 lower part, because battery package 8 occupies most space that separates the mouth, so separate the interior liquid level of mouth 7 and rise fast and submergence battery package to reach rapid cooling's purpose, can prevent effectively that the battery package from continuously generating heat the accident that leads to.

After the immersion system starts, water can remain always in separating mouthful 7, in order to discharge water before the staff opens door 11, set up drain pipe 5 in every bottom that separates mouthful 7, and set up the valve on drain pipe 5, the valve is in the closed condition at ordinary times, opens the valve, separates the water in mouthful 7 and passes through the drain pipe and discharge, after liquid has flowed, opens door 11 again, can take out the battery package this moment, carries out the later maintenance work.

For facilitating drainage, the water outlets of the same row of drainage pipes 5 are connected with the same drainage pipe 6, the tail outlet of the drainage pipe 6 is communicated with the outside of the cabinet 9, and as shown in fig. 3, the tail end of the drainage pipe 6 extends out of the side wall of the cabinet 9. Liquid flowing out of the drainage pipe 5 is discharged to the outside of the cabinet body 9 after passing through the flow guide pipe 6, and under the guiding action of the flow guide pipe 6, the liquid directly flows to the outside of the cabinet body 9, so that the liquid is prevented from falling into the cabinet body 1.

To meet the simultaneous submergence of all the compartments 7, the preset capacity of the bottle 1 can submerge the battery packs in all the compartments 7, and when only not all the spray heads 4 spray water, if one compartment 7 is in trouble, the total outflow of water will exceed the capacity of these compartments 7. Therefore, the rear air hole 19 is arranged on the upper part of the rear wall of the bin opening 10, the highest liquid level in the partition opening 7 is the rear air hole 19 at the lowest part, and the excessive water is discharged through the rear air hole 19 arranged on the rear wall of the partition opening 7, so that the immersion system can be normally stopped (the water in the medicine bottle 1 can normally flow out), and the aim of controlling the liquid level can be fulfilled.

In addition, the charging and replacing cabinet is provided with an exhaust device, and as shown in fig. 1, an exhaust fan is arranged on the rear wall of the fire-fighting chamber 13. In the embodiment, a hollow interlayer is arranged between two rows of partition ports 7; an inner air hole 18 is arranged on the side wall between the partition 7 and the hollow interlayer, a front air hole 17 is arranged on the front panel of the hollow interlayer, and the whole height of the inner air hole 18 is higher than that of a rear air hole 19 in order to prevent water from flowing into the hollow interlayer from the inner air hole 18; the air hole 17 gets into the cavity intermediate layer through preceding gas pocket after the air discharge fan starts, then gets into each through interior gas hole 18 and separates mouthful 7 to through back gas pocket 19 outflow and separate mouthful 7, the gaseous confluence of outflow is in the operation room, and upwards passes through the air discharge fan, discharges the cabinet body 9 through the air discharge fan at last.

As shown in fig. 3, the main line 2, the branch lines 3, the drain pipe 5, and the flow guide pipe 6 are all provided on the rear wall of the partition 7, and the valve on the drain pipe 5 can be operated by opening the rear cabinet door 16, and other lines and the like can be installed in the operating room.

In this embodiment, because the medicine bottle is located at the upper portion of the cabinet body, the medicine bottle can be set to be open, and water can also flow downwards normally under the action of water pressure. If the medicine bottle is disposed at the lower portion of the cabinet, it is necessary to use a high-pressure medicine bottle.

It should be noted that the charging and converting cabinet that has been laid should include various circuit systems, and the solution proposed by the present invention is only a new solution proposed for the cabinet body, and in the actual production, it is necessary to use the solution as a carrier for the cabinet body, and other various circuit systems are provided, and these circuit systems are the prior art, so these components are not described in this application.
