Description
Technical Field
[0001] This utility model belongs to the technical field of battery swapping cabinets, and in particular relates to a battery swapping cabinet with a spray-type fire extinguishing structure. Background Technology
[0002] Electric vehicles are typically equipped with stationary rechargeable batteries. For extended periods of use, the downtime caused by charging is inconvenient, such as in the food delivery industry where continuous use of electric vehicles is required. To eliminate this waiting time, removable rechargeable new energy batteries are ideal. Designated charging stations with multiple battery compartments are also necessary. Users can log in by scanning a code and then designate a specific battery for replacement, swapping depleted and fully charged batteries to achieve rapid full charging.
[0003] The battery swapping cabinets, placed in open-air locations along streets and roadsides, resemble parcel lockers in shape. Inside, there are battery compartments for storing battery boxes, each with its own charger. The charging is controlled by an electronic system on top, activating the corresponding charger. Users place the depleted battery into the compartment, insert the corresponding charger plug into the battery's charging port, and the battery begins charging for the next swap. Although the battery compartments are independent units equipped with a heat dissipation system, in high-temperature environments, the battery temperature rises due to repeated charging and discharging, and combined with battery and wiring aging, fires are highly likely. A fire in one battery compartment can potentially burn down multiple compartments simultaneously, with serious consequences. Utility Model Content
[0004] The purpose of this utility model is to provide a battery swapping cabinet with a spray-type fire extinguishing structure, equipped with a fire extinguishing system. A water tank is set at the bottom of the cabinet and connected to each battery compartment through pipelines. The battery compartment is equipped with a smoke alarm, which sprays water to extinguish the fire in the battery compartment at the initial stage of the fire to prevent the fire from spreading.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] A battery swapping cabinet with a spray-type fire extinguishing structure includes a cabinet body, which is a shell structure made of sheet metal. In the internal cavity, the upper layer is an electrical control compartment, the middle layer has multiple battery compartments arranged and installed, and the bottom layer has a water tank.
[0007] The battery compartment is a cubic structure with an opening on one side, and the opening side has a door corresponding to the front side of the cabinet. Each battery compartment is equipped with a nozzle on its top, and each nozzle is connected in parallel to the main pipe through branch pipes. The main pipe extends to the water tank and is connected in series with a micro diaphragm pump. Each branch pipe is independently connected in series with a solenoid valve for control.
[0008] A smoke detector is installed on the top of the cabinet.
[0009] Furthermore, the battery compartment sidewall has heat dissipation holes and is equipped with a cooling fan, and a charger is also independently installed on the battery compartment sidewall.
[0010] Furthermore, the nozzle is located at the top of the battery compartment, which has a mounting hole and a housing covering the mounting hole. One side of the housing is open, and the housing has an internal groove for accommodating the nozzle. The side of the housing corresponding to the open side has a folding plate for aligning with the mounting hole in the battery compartment and is secured with screws.
[0011] Furthermore, the battery compartment is installed at an angle within the cabinet, and the rear door of the cabinet is on the lower side. A drain hole is provided on the lower side of the battery compartment. A manifold is installed on the rear side of the cabinet, and it has a manifold channel. The drain holes corresponding to the battery compartment are all connected to the manifold channel, and the bottom of the manifold channel is connected to a water tank.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figures 1-4 The diagram shows a battery swapping cabinet with a spray-type fire extinguishing structure, comprising a cabinet body 1, which is a sheet metal shell structure. Inside the cavity, the upper layer is an electrical control compartment 2, housing electrical control equipment, a general-purpose distribution panel, etc. A closable door is located on the front of the cabinet, containing a camera, lighting components, etc. Multiple battery compartments 3 are arranged in the middle layer, and a water tank 4 is installed at the bottom. The battery compartments are arranged sequentially from top to bottom for storing batteries. The water tank stores water for fire extinguishing in case of fire.
[0021] The battery compartment 3 is a cubic structure with an opening on one side, and the opening side has a door corresponding to the front side of the cabinet 1. Each battery compartment 3 is equipped with a nozzle 7 on its top. Each nozzle 7 is connected in parallel to the main pipe through a branch pipe. The main pipe extends to the water tank 4. The main pipe is connected in series with a micro diaphragm pump 5. Each branch pipe is independently connected in series with a solenoid valve 6 for control. The attached figure shows the position of the branch pipe and the main pipe. Both the branch pipe and the main pipe are epoxy resin hoses.
[0022] A smoke detector 11 is installed on the top of cabinet 1.
[0023] Each battery compartment is equipped with a solenoid valve, which is installed on the rear panel of the battery compartment. The branch pipe is connected to the main pipe, which in turn is connected to the water tank. Power is supplied by a miniature diaphragm pump. When a fire occurs due to a battery problem or wiring issue in a single battery compartment, smoke will appear first. Once the smoke detector senses the smoke, it will activate the nozzle of the corresponding battery compartment to spray water into the battery compartment, providing timely cooling and fire extinguishing. This extinguishes the fire at the smoke stage and effectively prevents the fire from spreading and causing greater losses.
[0024] like Figure 3 As shown: The side wall of battery compartment 3 has ventilation holes and is equipped with a cooling fan 31. A charger 32 is also independently installed on the side wall of battery compartment 3. Each battery compartment is independently equipped with a charger and is charged independently. The charger has a cable and a charging interface, and the cable is introduced into the battery compartment through the ventilation holes in the side wall. The cooling fan cools the battery compartment by using unidirectional airflow.
[0025] The nozzle 7 is located on top of the battery compartment 3. The top of the battery compartment 3 has a mounting hole 33 and a housing 71 covering the mounting hole. One side of the housing 71 is open, and the interior has a groove to accommodate the nozzle 7. In the event of a fire alarm, the nozzle sprays atomized water droplets to cover the inside of the battery compartment. The housing 71 has a folding plate 72 on the side corresponding to the open side, which aligns with the mounting hole in the battery compartment 3 and is secured with screws. For convenient installation of the nozzle assembly, after the battery compartment is formed, the mounting hole is punched, and then the housing and nozzle are installed as a whole on top of the battery compartment.
[0026] like Figure 2 As shown: Battery compartment 3 is installed at an angle within cabinet 1, and its lower side corresponds to the rear door position of cabinet 1. A drain hole is provided on the lower side of battery compartment 3. The battery compartment is installed with a higher front and lower back, with the opening side being higher. This design prevents batteries from slipping and falling out after insertion, and also helps collected sprayed water at the rear of the battery compartment, allowing it to be drained through the drain hole in a timely manner, preventing the electronic components inside the battery compartment from becoming soaked and damaged. A manifold 8 with a manifold channel is installed on the rear side of cabinet 1. The drain hole corresponding to battery compartment 3 is connected to the manifold channel, and the bottom of the manifold channel is connected to the water tank 4. Sprayed water can be collected through the manifold channel and recycled into the water tank for reuse, conserving water.
[0027] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
