Description

Technical Field

[0001] The utility model belongs to the technical field of charging pile fire prevention equipment, and particularly relates to a charging pile device capable of extinguishing fire. Background Art

[0002] Charging piles are essential equipment for providing power to electric vehicles. Charging piles operate at high voltages and currents, and internal electronic components and wiring can pose a risk of electrical fires due to overload, short circuits, or aging. Furthermore, heat buildup during charging, along with prolonged charging periods or charging in high-temperature environments, can cause internal temperatures to rise, increasing the likelihood of fire. With the increasing popularity of electric vehicles in recent years, the number of charging piles has continued to grow, necessitating the installation of fire-extinguishing devices on charging piles to mitigate potential safety hazards such as fires.

[0003] In the prior art, Chinese patent document CN220764127U, for example, provides a fireproof charging pile comprising a charging pile body enclosed within a fireproof housing, a charging gun disposed outside the fireproof housing, and a blasting fire extinguishing device installed on top of the fireproof housing. This fireproof charging pile, by installing a blasting fire extinguishing device, addresses the fire safety issues associated with existing charging piles to a certain extent. However, the blasting fire extinguishing device installed on this charging pile is fixed in place, lacking the flexibility of traditional fire extinguishers for immediate use, potentially delaying the optimal time to extinguish a fire. Furthermore, existing automatic fire extinguishing devices require a fire to be close to the ground to trigger. Charging piles are prone to fires due to electrical faults, overloads, and other factors. Existing automatic fire extinguishing devices are unable to quickly respond and extinguish flames in the early stages of an electrical fault, increasing the risk of damage to the charging pile itself, the charging vehicle, and surrounding facilities.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a charging pile device that can extinguish fires to meet the configuration requirements of the charging pile fire safety. Summary of the Invention

[0005] In response to the problems in the related technology, the present invention proposes a charging pile device that can extinguish fires to solve technical problems such as the relatively fixed position of existing charging pile fire extinguishing devices, poor flexibility, and inability to quickly extinguish initial fires.

[0006] The technical solution of the utility model is implemented as follows: a charging pile device capable of extinguishing fire includes a charging pile body, the charging pile body includes a housing, the housing has a built-in charging module, the charging module is connected to a charging gun via a cable, and the charging gun is inserted outside the housing;

[0007] A metal bracket is fixedly provided on the back of the housing, and a fire extinguishing body is accommodated on the metal bracket; the fire extinguishing body includes a container for containing a fire extinguishing agent, a valve is provided at the top outlet of the container, the valve is connected to a switch handle for controlling the opening and closing of the valve output end, and the valve output end is connected to a telescopic nozzle;

[0008] The device further comprises a tension and compression module, the tension and compression module comprising a drive unit, the output end of the drive unit being detachably connected to the switch handle via a pull rope; the charging module being placed on one side of the housing, the ejection direction of the telescopic nozzle being directed toward the charging module; the fire extinguishing body being provided with a guide rail near the charging module, the guide rail being slidably connected to a slider, the slider being detachably connected to the telescopic nozzle;

[0009] It also includes a control unit. A plurality of flame detectors are provided on the outside of the casing near the charging module. The control unit is electrically connected to the flame detectors and the tension and compression modules respectively.

[0010] In this utility model, a fire extinguishing device is installed on the charging pile body, and the pull-and-press module realizes automatic fire extinguishing function, meeting the requirements of on-site fire protection configuration. At the same time, the fire extinguishing device and the charging pile body are configured to be detachable, compatible with handheld fire extinguishing. By separating the fire extinguishing device from the charging pile body, it can be used at any time. In addition, multiple flame detectors are installed on the charging pile body to realize fire monitoring during the charging process. This allows the fire extinguishing device to quickly respond and extinguish the flames in the early stage of a fire, effectively reducing damage to the charging pile itself, the charging vehicles, and surrounding facilities, thereby significantly reducing economic losses.

[0011] As a further improvement of the above solution, the charging gun is arranged on one side of the housing, and the charging module and the charging gun are on the same side; the telescopic nozzle faces the side where the charging module is located.

[0012] As a further improvement to the above solution, the charging guns are arranged on both sides of the housing, and the charging modules are provided with two, which are arranged corresponding to the charging guns; the valve output end is also connected to a diverter, and the diverter is respectively connected to a first telescopic nozzle and a second telescopic nozzle; the first telescopic nozzle and the second telescopic nozzle are respectively oriented toward the side where the corresponding charging module is located. The location of the charging interface of different vehicles or equipment may vary depending on the design. The dual charging gun layout allows the corresponding charging interface to be quickly found regardless of which side the vehicle is parked on the charging device. The first telescopic nozzle and the second telescopic nozzle are respectively oriented toward the side where the corresponding charging module is located to ensure that the output end of the fire extinguishing body is oriented toward the charging module, which can quickly extinguish the initial fire caused by electrical failure during the charging process.

[0013] As a further improvement to the above solution, the switch handle includes a pressing portion, which controls the opening and closing of the valve output end by pressing down or lifting the pressing portion; the end of the extended pull rope is provided with a pressure block, which presses against the upper end surface of the pressing portion. Traditional fire extinguishing methods often rely on manual detection of the fire and manual activation of the fire extinguishing device, which involves time delays and uncertainty due to human factors. However, this design uses a drive unit to drive the pull rope, pulling down the pressure block to form an automatic trigger mechanism, ensuring that the fire extinguishing system can be quickly activated in the early stages of a fire, effectively curbing the spread of the fire and improving the success rate of fire extinguishing. Its advantages of automatic fire extinguishing are particularly significant in unmanned or nighttime situations.

[0014] As a further improvement to the above solution, a U-shaped notch is provided on the outward side of the pressing portion. A curved guide surface is provided at the entrance of the U-shaped notch, through which the pull cord can be inserted or removed. The U-shaped notch facilitates the detachment of the pressing block and the pull cord, enabling the switch from automatic to manual fire extinguishing, meeting the need for on-the-go use.

[0015] As a further improvement to the above solution, the output end of the drive unit is pivotally connected to a drive sprocket, around which a chain is wound. One end of the chain is fixed to the drive sprocket, and the other end is connected to the pull rope. This design allows the chain to maintain a stable shape when subjected to tension, preventing malfunctions caused by loosening or falling off. It also makes regular inspection and replacement of the chain relatively easy, further improving the durability of the system.

[0016] As a further improvement to the above solution, the switch handle also features a lifting handle fixed to the top of the container. The pressing portion pivots relative to the lifting handle about a pivot, and a return spring is provided at the pivot. The drive unit drives the pressure block downward to press the pressing portion, opening the valve output; the return spring drives the pressing portion upward to close the valve output. The lifting handle facilitates lifting the fire extinguisher during manual fire extinguishing, and the return spring facilitates the return of the pressing portion after being pressed downward, thereby improving the reliability of automatic fire extinguishing.

[0017] As a further improvement of the above solution, the driving unit is fixed on the back of the housing and placed below the handle.

[0018] As a further improvement to the above solution, the guide rail extends vertically, and the slider is provided with an elastic bayonet into which the telescopic nozzle engages. This engagement facilitates quick removal of the telescopic nozzle from the slider, making it compatible with handheld firefighting and providing increased flexibility.

[0019] As a further improvement to the above solution, the guide rail is equipped with transmission wheels at each end, one of which is driven by a transmission motor. A transmission belt is also included, which is wound around the transmission wheels at each end of the guide rail, and the slider is fixed to the transmission belt. The transmission wheels and transmission belt on the guide rail facilitate the upward and downward movement of the telescopic nozzle when the flame detector of the charging pile device senses a flame, achieving precise fire extinguishing.

[0020] Beneficial effects of the utility model:

[0021] (1) A fire extinguishing body is configured on the charging pile body, and the automatic fire extinguishing function is realized through the pull-press module to meet the on-site fire protection configuration requirements; at the same time, the fire extinguishing body and the charging pile body are set to be detachably connected, compatible with the handheld fire extinguishing method, and by separating the fire extinguishing body from the charging pile body, the use requirements of taking it with you are met;
