Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, and in particular to a fire extinguishing device for charging stations at gas stations. Background Technology

[0003] To meet the charging needs of new energy vehicle users, traditional gas stations, as important nodes in transportation hubs, are gradually planning and adding charging stations to form a comprehensive "refueling + charging" service model. However, the introduction of charging stations has also brought new challenges to the safety management of gas stations, especially the significantly increased risk of fire during the charging process.

[0004] Traditional fire hydrants and fixed fire monitors are mostly set up in refueling areas, while charging stations are often scattered on the edge of gas stations or in newly added areas. Fixed facilities cannot cover all charging stations, and vehicles may block the fire extinguishing path after parking.

[0005] Therefore, it is necessary to provide a new fire extinguishing device for gas station charging stations to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a fire extinguishing device for charging stations, which solves the problems that traditional fire hydrants and fixed fire monitors are mostly set up for refueling areas, while charging stations are often scattered on the edge of the gas station or in newly added areas, and fixed facilities cannot cover all charging stations, and vehicles may block the fire extinguishing path after parking.

[0007] The fire extinguishing device for charging positions at gas stations provided by the present invention includes a platform, on which a plurality of charging pile installation positions are arranged at intervals, a fire water tank is arranged on one side of the platform, a track is fixed on the platform, a movable platform is slidably arranged on the track, and a first column is fixed on the movable platform. The first column is fixed to a base, a bearing gear platform is movably mounted on the base, a second column is fixed on the bearing gear platform, a top seat is fixed to the top of the second column, a boss is fixed on the top seat, and an adjustment platform is movably mounted on the boss via a mounting shaft. The adjustment platform is equipped with a DC water spray gun, one end of which can be connected to the fire pipe inside the fire water tank.

[0008] In a preferred embodiment, two lower ring seats are fixed at intervals on the adjustment platform, and an upper ring seat is provided above the lower ring seats. The DC water spray gun is located between the upper ring seat and the lower ring seat, and the upper ring seat and the lower ring seat are fixedly connected by several bolts.

[0009] In a preferred embodiment, an adjusting worm gear is mounted on the mounting shaft, and two first mounting seats are mounted at intervals on the top seat, with an adjusting worm gear movably disposed between the two first mounting seats via a bearing; A first motor is mounted on the top seat, and the output end of the first motor is connected to the adjusting worm gear via a coupling.

[0010] In a preferred embodiment, the adjusting worm and the adjusting worm wheel employ a closed transmission.

[0011] In a preferred embodiment, a second motor is installed on one side of the bottom of the base, a second mounting base is fixed on one side of the base, a rotating shaft is movably disposed on the second mounting base, the bottom of the rotating shaft is connected to the output end of the second motor through a coupling, and an adjusting gear is installed on the top of the rotating shaft, the adjusting gear meshing with the bearing gear table.

[0012] In a preferred embodiment, a displacement motor is mounted on the moving platform, and a displacement gear is mounted on the output end of the displacement motor; A support is installed on the platform, and a rack is installed on the top of the support. The rack meshes with the displacement gear.

[0013] In a preferred embodiment, the adjusting gear, the bearing gear platform, the displacement gear, and the rack are all galvanized.

[0014] In a preferred embodiment, a smoke alarm module and a wireless control module are installed on one side of the second column.

[0015] In a preferred embodiment, a plurality of inclined support rods are fixed between the first column and the mobile platform.

[0016] The beneficial effects of this invention are: 1. The device utilizes a sliding connection between a track and a mobile platform, combined with a displacement motor driving a displacement gear and rack transmission, enabling the mobile platform to move rapidly along the track to the vicinity of any charging pile installation location. Compared to fixed fire extinguishing facilities, this design overcomes spatial limitations, covering multiple dispersed charging locations and solving the problems of "limited coverage and vehicle obstruction" in traditional fixed fire extinguishing devices.

[0017] 2. Horizontal direction: The second motor drives the adjusting gear to mesh with the bearing gear table, which can drive the second column to rotate, flexibly adjusting the horizontal direction of the DC water spray gun to adapt to fire sources in different horizontal positions such as the side and front of the vehicle. Vertical direction: The first motor drives the adjusting worm gear and adjusting worm wheel to make the mounting shaft drive the adjusting platform to rotate, so as to realize the adjustment of the pitch angle of the DC water spray gun, which can cover the vertical range from the bottom to the top of the vehicle; The combination of the two enables precise targeting of the fire source, solving the problem that traditional devices have "limited adjustment range and cannot adapt to fire sources in different locations".

[0018] 3. The smoke alarm module can monitor the smoke concentration at the charging position in real time. Once a fire is detected, it can quickly trigger a signal. In conjunction with the wireless control module, the displacement motor, the first motor, and the second motor can be remotely controlled to start. The response speed of the entire process from fire detection to device arrival, adjustment, and water spraying is significantly improved, which helps to control the fire in the early stages of a fire and prevent it from spreading.

[0019] 4. The adjusting gear, bearing gear table, displacement gear and rack are all galvanized to enhance their resistance to oil and gas corrosion and rainwater corrosion, ensuring that the transmission structure is not prone to jamming in the humid and corrosive environment of the gas station. The first column is fixed with an inclined support rod between it and the moving platform, which improves the overall structure's resistance to overturning, and can remain stable even under the reaction force of high-pressure water flow. The adjusting worm and adjusting worm wheel adopt a closed transmission, which reduces the impact of dust and moisture on the transmission and ensures the adjustment accuracy.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in Figure 1 A schematic diagram of the overall structure of the fire extinguishing device for the charging position of a gas station provided by the present invention; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 This is a structural schematic diagram of the fire water tank provided by the present invention; Figure 4 A perspective view of the main structure of the fire extinguishing device for the charging station of the present invention; Figure 5 The main structural plan view of the fire extinguishing device for the charging position of a gas station provided by the present invention.

[0024] In the specific implementation process, such as Figures 1-5 As shown, the system includes a platform 1, on which a number of charging pile installation positions 2 are spaced apart. A fire water tank 3 is installed on one side of the platform 1. A track 4 is fixed on the platform 1. A movable platform 5 is slidably mounted on the track 4. A first column 6 is fixed on the movable platform 5. A number of inclined support rods 31 are fixed between the first column 6 and the movable platform 5. The angle between the support rods and the column and the movable platform is 45°, which improves the overall anti-overturning ability.

[0025] A base 7 is fixed to the top of the first column 6. A bearing gear platform 8 is movably mounted on the base 7. A second column 9 is fixed to the bearing gear platform 8. A top seat 10 is fixed to the top of the second column 9. A boss 11 is fixed to the top seat 10. An adjustment platform 13 is movably mounted on the boss 11 via an installation shaft 12. A DC water spray gun 14 is mounted on the adjustment platform 13. One end of the DC water spray gun 14 can be connected to the fire pipe inside the fire water tank 3. Pre-set installation positions 2 are arranged at intervals according to the charging pile layout on the surface of the platform 1. A concrete base is poured on one side of the platform 1 to fix the fire water tank 3, ensuring that the water tank capacity meets the fire extinguishing needs of at least 3 charging positions at the same time. The water tank capacity is recommended to be ≥500L. Two tracks 4 are laid parallel to each other along the length of the platform 1. The tracks 4 are fixed to the platform 1 with expansion bolts. The joints are sealed to prevent water accumulation.

[0026] Two lower ring seats 15 are fixed at intervals on the adjustment platform 13, and an upper ring seat 16 is provided above the lower ring seats 15. The DC water spray gun 14 is located between the upper ring seat 16 and the lower ring seat 15. The upper ring seat 16 and the lower ring seat 15 are fixedly connected by several bolts.

[0027] An adjusting worm gear 17 is mounted on the mounting shaft 12. Two first mounting seats 18 are installed at intervals on the top seat 10. An adjusting worm 19 is movably arranged between the two first mounting seats 18 via a bearing. The adjusting worm 19 and the adjusting worm gear 17 adopt a closed transmission to improve their service life. A first motor 20 is mounted on the top seat 10. The output end of the first motor 20 is connected to the adjusting worm 19 via a coupling. When the first motor 20 is started, the adjusting worm 19 and the worm gear 17 are in closed transmission, which is dustproof and has a transmission efficiency of ≥90%. The mounting shaft 12 drives the adjusting platform 13 to rotate, changing the pitch angle of the DC water spray gun 14 to achieve full coverage from ground (battery compartment) fire to vehicle top (cabin) fire.

[0028] A second motor 21 is installed on one side of the bottom of the base 7, and a second mounting base 22 is fixed on one side of the base 7. A rotating shaft 23 is movably mounted on the second mounting base 22. The bottom of the rotating shaft 23 is connected to the output end of the second motor 21 through a coupling. An adjusting gear 24 is installed on the top of the rotating shaft 23. The adjusting gear 24 meshes with the bearing gear table 8. The second motor 21 is remotely started through the wireless control module 30. The rotating shaft 23 drives the adjusting gear 24 to rotate. Because the adjusting gear meshes with the bearing gear table 8, the bearing gear table 8 drives the second column 9 to rotate, so that the DC water gun 14 is horizontally aimed at a fire source such as a charging interface or the side of the vehicle body.

[0029] A displacement motor 25 is installed on the moving platform 5, and a displacement gear 26 is installed at the output end of the displacement motor 25. A support 27 is installed on the base 1, and a rack 28 is installed on the top of the support 27. The rack 28 meshes with the displacement gear 26.

[0030] The adjusting gear 24, the bearing gear platform 8, the displacement gear 26, and the rack 28 are all galvanized to resist corrosion from oil and gas at gas stations and improve their service life.

[0031] A smoke alarm module 29 and a wireless control module 30 are installed on one side of the second column 9. The wireless control module 30 and the smoke alarm module 29 are installed together on one side of the second column 9 to facilitate receiving signals from the smoke alarm module and establishing communication connections with external control terminals and motors (first motor 20, second motor 21, displacement motor 25) in the device.

[0032] Its specific structure includes: Wireless transceiver unit: The core is a wireless communication chip (such as a 4G module, Bluetooth module or LoRa module, adapted to the communication distance and anti-interference requirements of the gas station environment), including a radio frequency antenna and a modem, used to realize wireless signal transmission with remote control terminals (such as duty room computers, handheld remote controls), receive remote control commands and provide feedback on the device's operating status.

[0033] Microcontroller Unit (MCU): As the core control component of the module (e.g., using an STM32 series microcontroller), it processes input signals (including alarm signals from the smoke alarm module and remote control commands) and outputs control signals according to preset logic. For example, upon receiving a smoke alarm signal, it can automatically trigger the start command of the displacement motor 25; upon receiving an angle adjustment command from a remote terminal, it outputs a signal to control the operation of the first motor 20 or the second motor 21.

[0034] Signal input interface: Connected to the alarm output interface of the smoke alarm module 29 via a wire to receive smoke concentration exceeding the standard; it may also include a status detection interface for collecting motor operating status (such as current, position feedback).

[0035] Control output interface: It is connected to the control terminals of the first motor 20, the second motor 21, and the displacement motor 25 through relays or drive circuits, and converts the weak electrical control signals output by the MCU into strong electrical signals that can drive the motors to run (such as forward and reverse control and start and stop control of DC motors).

[0036] Power supply module: Connects to the overall power supply system of the device (such as fire control circuit) to provide a stable DC power supply (such as 5V or 12V), including power protection circuits (such as overcurrent and overvoltage protection) to ensure that the module works reliably in emergency situations.

[0037] Working principle of the invention: When this fire extinguishing device is in use, when the smoke alarm module 29 detects that a car is burning, the displacement motor 25 is started to drive the displacement gear 26 to rotate. Under the transmission action of the displacement gear 26 and the rack 28, the moving platform 5 will move along the track 4 to the vicinity of the corresponding installation position 2. Then the staff will connect the pipes inside the fire water tank 3 to the DC water spray gun 14. Finally, the first motor 20 and the second motor 21 can be remotely controlled by the wireless control module 30. Starting the first motor 20 can drive the adjusting gear 24 to rotate. Under the action of the adjusting gear 24, the bearing gear table 8 will drive the second column 9 to rotate, ultimately changing the spray direction of the DC water gun 14. Starting the second motor 21, under the transmission action of the adjusting worm 19 and the adjusting worm wheel 17, the mounting shaft 12 will drive the entire adjusting platform 13 to rotate, thereby changing the spray height of the DC water gun 14.

[0038] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
