Description

Technical Field

[0001] The utility model belongs to the technical field of power exchange cabinets, and specifically relates to a cone-shaped fire sprinkler device suitable for an intelligent power exchange cabinet. Background Art

[0002] Amid the current trend of energy transition and green mobility, electric vehicles are becoming increasingly popular due to their significant advantages, such as environmental friendliness and energy efficiency. To meet the demand for convenient and efficient energy replenishment for electric vehicles, smart battery swap cabinets have emerged as an innovative solution. However, with the widespread use of smart battery swap cabinets, safety concerns, particularly fire hazards, have become increasingly prominent, becoming a key factor hindering their further development and widespread adoption.

[0003] Batteries, the core components of smart battery swap cabinets, can malfunction and potentially cause fires due to a variety of complex factors during frequent charging and discharging. For example, chemical imbalances within the battery, electrode aging, circuit shorts, overcharging or discharging can cause the battery temperature to rise sharply, exceeding safety thresholds and potentially causing a fire.

[0004] When a fire occurs in a battery within a smart battery swap cabinet, the high temperature and smoke generated by the fire spread rapidly due to the relatively closed interior of the cabinet and the tightly packed batteries. On the one hand, the high temperature is quickly transferred to adjacent batteries through heat conduction and radiation, exposing these previously healthy batteries to high temperatures and making them susceptible to overheating and combustion, leading to secondary fires and even chain reactions, causing the fire to spread further. On the other hand, the smoke generated by the fire not only affects the observation and judgment of the fire, but may also contain toxic and hazardous substances, posing a serious threat to the surrounding environment and the lives and health of people.

[0005] Existing firefighting technologies for smart battery swap cabinets have numerous shortcomings in common firefighting methods and devices. While some traditional firefighting methods, such as dry powder firefighting, can extinguish flames to a certain extent, dry powder can corrode and damage the batteries and electronic equipment within the cabinet, impacting the subsequent normal operation of the battery swap cabinet. Furthermore, conventional water sprinkler systems often fail to precisely extinguish the burning battery, resulting in a waste of water resources. Furthermore, their firefighting speed and effectiveness are insufficient to quickly extinguish a fire and prevent its spread.

[0006] At the same time, existing firefighting measures often lack effective cooling mechanisms for batteries that haven't caught fire. In the event of a fire, relying solely on the cabinet's own insulation is insufficient to protect against the high temperatures. Prolonged exposure to high temperatures can cause performance degradation or even damage to batteries that haven't caught fire, increasing subsequent repair costs and safety risks.

[0007] To this end, we have proposed a conical fire sprinkler device suitable for smart battery swap cabinets. This device can quickly extinguish fires by isolating oxygen and cooling water. At the same time, it can cool down and seal the remaining batteries to prevent secondary fires, improve the cooling effect, and reduce cost losses. Utility Model Content

[0008] The purpose of this utility model is to provide a conical fire sprinkler device suitable for an intelligent battery exchange cabinet, which can achieve the effect of rapid fire extinguishing by isolating oxygen and cooling water, and at the same time can cool down and seal the remaining batteries to prevent secondary fire, thereby improving the cooling effect and reducing cost losses.

[0009] The technical solutions adopted in this application are as follows:

[0010] A conical fire sprinkler device suitable for an intelligent battery swap cabinet comprises a rectangular cabinet, wherein the rectangular cabinet is provided with a water inlet pipe and a rectangular cavity, the water inlet pipe is provided with a first water pump, and the water inlet pipe is connected to the rectangular cavity, a plurality of U-shaped frames for supporting batteries are provided inside the rectangular cabinet, each of the U-shaped frames is provided with a mounting hole, a telescopic tube is provided inside the mounting hole, a connecting pipe connected thereto is provided at the bottom of the telescopic tube, a rectangular sealing frame for sealing the battery is provided on the connecting pipe, and a conical nozzle located inside the rectangular sealing frame is provided at the bottom of the connecting pipe, a water conduit connected to the rectangular cavity is provided at the top of the telescopic tube, and an electric control valve is provided on the water conduit;

[0011] A first connecting rod is provided between every two rectangular sealing frames, a telescopic component is provided on the top U-shaped frame, a second connecting rod is provided at the telescopic end of the telescopic component, and the bottom of the second connecting rod is connected to the top rectangular sealing frame.

[0012] Furthermore, a temperature sensor is provided inside the U-shaped frame.

[0013] Furthermore, a heat absorbing layer is provided on the inner wall of the rectangular cabinet.

[0014] Furthermore, a shielding plate is provided on the rectangular cabinet.

[0015] Furthermore, the U-shaped frame is hinged with a sealed door.

[0016] Furthermore, the telescopic assembly includes an electric telescopic rod arranged on the U-shaped frame, and the electric telescopic rod is connected to the second connecting rod.

[0017] The technical effects achieved by this utility model are:

[0018] When a fire occurs in the battery swap cabinet (for example, when a battery inside one of the U-shaped frames catches fire), the first water pump provides power at this time, and the outside water enters the rectangular cavity through the water inlet pipe, so that the rectangular cavity is filled with cooling water. This setting can cool the batteries inside the entire rectangular cabinet to prevent temperature transfer, which may cause the remaining batteries that have not caught fire to catch fire again due to excessive temperature. At the same time, the telescopic component is activated, and the telescopic component drives the second connecting rod to move the top rectangular sealing frame downward. The top rectangular sealing frame drives the other rectangular sealing frames of the first connecting rod to seal the corresponding batteries (at this time, the rectangular sealing frame moves by the telescopic action of the telescopic tube), thereby preventing the batteries that have not caught fire from being affected and catching fire. At the same time, the batteries that have caught fire are sealed by the rectangular sealing frame, thereby isolating oxygen and achieving the effect of rapid fire extinguishing. At the same time, the temperature sensor inside the U-shaped frame where the fire has occurred senses the fire and controls the corresponding electric control valve to open. The pressure generated by the first water pump causes the cooling water to enter the telescopic tube and the connecting pipe through the opened water guide pipe, and then spray the cooling water through the conical nozzle to extinguish the fire, thereby achieving the effect of rapid fire extinguishing. The device can quickly extinguish fires by isolating oxygen and cooling water, while also cooling and sealing the remaining batteries to prevent secondary fires, thereby improving the cooling effect and reducing cost losses.

[0025] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0026] like Figure 1-4 As shown, the technical solution adopted in this utility model is as follows: a conical fire sprinkler device suitable for an intelligent battery swap cabinet, comprising a rectangular cabinet 1, a water inlet pipe 2 and a rectangular cavity 3 are provided on the rectangular cabinet 1, a first water pump is provided on the water inlet pipe 2, and the water inlet pipe 2 is connected to the rectangular cavity 3, a plurality of U-shaped frames 4 for carrying batteries are provided inside the rectangular cabinet 1, each U-shaped frame 4 is provided with a mounting hole, a telescopic tube 5 is provided inside the mounting hole, a connecting pipe 6 connected thereto is provided at the bottom of the telescopic tube 5, a rectangular sealing frame 7 for sealing the battery is provided on the connecting pipe 6, and a conical nozzle 8 located inside the rectangular sealing frame 7 is provided at the bottom of the connecting pipe 6, a water guide pipe 9 connected to the rectangular cavity 3 is provided at the top of the telescopic tube 5, and an electric control valve is provided on the water guide pipe 9;

[0027] A first connecting rod 10 is provided between every two rectangular sealing frames 7 , a telescopic assembly is provided on the top U-shaped frame 4 , a second connecting rod 11 is provided at the telescopic end of the telescopic assembly, and the bottom of the second connecting rod 11 is connected to the top rectangular sealing frame 7 .

[0028] Its working principle is: when a fire occurs in the battery exchange cabinet (for example, when a fire occurs in a battery inside one of the U-shaped frames 4), power is provided by the first water pump at this time, and the water from the outside enters the rectangular cavity 3 through the water inlet pipe 2, so that the rectangular cavity 3 is filled with cooling water. This setting can cool down the batteries inside the entire rectangular cabinet 1 to prevent temperature transfer, which causes the remaining batteries that have not caught fire to catch fire again due to excessive temperature. At the same time, the telescopic component is started, and the telescopic component drives the second connecting rod 11 to move the top rectangular sealing frame 7 downward, and the top rectangular sealing frame 7 drives the first connecting rod 10 and the rest of the rectangular The sealing frame 7 seals the corresponding battery (at this time, the rectangular sealing frame 7 moves through the telescopic effect of the telescopic tube 5), thereby preventing the battery that has not caught fire from being affected and catching fire. At the same time, the battery that has caught fire is sealed by the rectangular sealing frame 7, thereby isolating oxygen and achieving the effect of rapid fire extinguishing. At the same time, the temperature sensor inside the U-shaped frame 4 where the fire has occurred senses the fire and controls the corresponding electric control valve to open. The pressure generated by the first water pump causes the cooling water to enter the telescopic tube 5 and the connecting pipe 6 through the opened water pipe 9, and then the cooling water is sprayed out through the conical nozzle 8 to extinguish the fire, thereby achieving the effect of rapid fire extinguishing. This device can achieve the effect of rapid fire extinguishing by isolating oxygen and cooling water. At the same time, it can cool the remaining batteries and seal them to prevent secondary fires, improve the cooling effect, and reduce cost losses.

[0029] A temperature sensor is provided inside the U-shaped frame 4 , and the temperature sensor can be used to determine which U-shaped frame 4 has a fire.

[0030] At the same time, a heat-absorbing layer is provided on the inner wall of the rectangular cabinet 1, through which the heat generated by the battery can be transferred to the inside of the rectangular cavity 3, thereby being absorbed by the incoming cooling water, cooling down the batteries inside the entire rectangular cabinet 1, and preventing temperature transfer, which would cause the remaining batteries that did not catch fire to catch fire again due to excessive temperature.

[0031] The telescopic tube 5 is a rubber telescopic hose in the prior art. This arrangement can drive the telescopic tube 5 to move downward when the rectangular sealing frame 7 moves, thereby meeting the displacement requirement.

[0032] A baffle 12 is provided on the rectangular cabinet 1 to prevent the rectangular sealing frame 7 and the entire spray assembly (connecting pipe 6, telescopic end, water pipe 9, electric control valve, conical nozzle 8) from being exposed to the air and causing damage.

[0033] It should be noted that the present invention provides one group of rectangular cabinets 1, and may also provide two or three groups, which belongs to the prior art and will not be described in detail here.

[0034] The U-shaped frame 4 is hinged with a sealing door (not shown in the figure), through which the battery can be sealed.

[0035] The telescopic assembly includes an electric telescopic rod 13 provided on the U-shaped frame 4 . The electric telescopic rod 13 is connected to the second connecting rod 11 . The electric telescopic rod 13 drives the second connecting rod 11 to move.

[0036] It also includes a controller, which is a programmable PLC controller. The controller is electrically connected to electrical components such as the electric control valve, the electric telescopic rod 13, and the first water pump. The connection of the controller realizes intelligent control, which belongs to the existing technology and will not be described in detail here.

[0037] The electric control valve, the electric telescopic rod 13 and the first water pump are started and shut down by the controller.

[0038] The electric control valve uses a solenoid valve as a pilot valve and controls the opening and closing of the valve through hydraulic operation. Its model is 600X-16Q electric control valve.

[0039] The working principle of the utility model is as follows: when a fire occurs in the battery exchange cabinet (for example, a fire occurs in a battery inside one of the U-shaped frames 4), power is provided by the first water pump at this time, and water from the outside enters the rectangular cavity 3 through the water inlet pipe 2, so that the rectangular cavity 3 is filled with cooling water. This setting can cool down the batteries inside the entire rectangular cabinet 1 to prevent temperature transfer, which causes the other batteries that have not caught fire to catch fire again due to excessive temperature. At the same time, the telescopic component is started, and the telescopic component drives the second connecting rod 11 to move the top rectangular sealing frame 7 downward, and the top rectangular sealing frame 7 drives the first connecting rod 10 and the rest The rectangular sealing frame 7 seals the corresponding battery (at this time, the rectangular sealing frame 7 moves due to the telescopic effect of the telescopic tube 5), thereby preventing the battery that is not on fire from being affected and catching fire. At the same time, the battery that is on fire is sealed by the rectangular sealing frame 7, thereby isolating oxygen, achieving the effect of rapid fire extinguishing. At the same time, the temperature sensor inside the U-shaped frame 4 where the fire is occurring senses the fire and controls the corresponding electric control valve to open. The pressure generated by the first water pump causes the cooling water to enter the telescopic tube 5 and the connecting pipe 6 through the opened water pipe 9, and then the cooling water is sprayed out through the conical nozzle 8 to extinguish the fire, thereby achieving the effect of rapid fire extinguishing. This device can achieve the effect of rapid fire extinguishing by isolating oxygen and cooling water. At the same time, it can cool the remaining batteries and seal them to prevent secondary fires, improve the cooling effect, and reduce cost losses.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
