Description

Technical Field

[0001] The present invention relates to the technical field of parking lots, in particular to a parking space barrier and a parking lot. Background Art

[0002] With the increasing popularity of electric vehicles, fire protection in parking lots is gaining increasing attention. Traditional parking blockers only block vehicles and are unable to effectively cool down the bottom of electric vehicles in the event of a fire.

[0003] The battery packs of electric vehicles are usually installed at the bottom of the vehicle. Once a fire occurs, the fire often spreads rapidly from the bottom, and traditional fire-fighting equipment is difficult to effectively extinguish the fire source directly at the bottom.

[0004] In addition, electric vehicle fires have the characteristics of fast burning speed, high temperature, and easy re-ignition. If the fire cannot be controlled in time, it may trigger a chain reaction and cause greater losses.

[0005] Therefore, there is an urgent need for a device that combines vehicle blocking and fire prevention functions to improve parking lot safety. This device must not only provide basic vehicle blocking capabilities but also be able to quickly respond to fires and precisely extinguish the underside of vehicles, effectively controlling the fire and minimizing losses. To address these issues, existing technologies urgently need improvement. Summary of the Invention

[0006] The purpose of the embodiments of the present invention is to provide a parking space blocker and a parking lot, so as to cool down the bottom of electric vehicles and extinguish fires, thereby facilitating fire control in electric vehicles and improving parking lot safety. The specific technical solutions are as follows:

[0007] The first embodiment of the present application provides a parking space stopper, comprising:

[0012] The water supply assembly includes a water supply pipe, and the water supply pipe is connected to the storage vertical pipe;

[0013] Under the water pressure of the fire-fighting water provided by the water supply pipe, the fire-fighting water enters the water spraying pipeline through the receiving vertical pipe, pushes the water spraying pipeline out of the receiving vertical pipe, and enables at least one first fire-fighting sprinkler to spray water on the bottom of the vehicle.

[0014] In some embodiments, the water spray pipeline is a multi-stage telescopic nozzle, and at least one first fire sprinkler head is provided on each stage of the telescopic nozzle;

[0015] Under the water pressure of the fire water provided by the water supply pipe, each stage of the telescopic nozzle extends from the storage vertical pipe along the length direction of the parking space.

[0019] In some embodiments, the horizontal bar is a horizontal tube;

[0020] The water supply pipe is directly connected to one end of the horizontal pipe, and the vertical storage pipe is directly connected to the horizontal pipe and the water spray pipe respectively. The fire water provided by the water supply pipe passes through the horizontal pipe, the vertical storage pipe and the water spray pipe in sequence to supply water to at least one first fire sprinkler.

[0021] In some embodiments, the horizontal pipe and / or the receiving vertical pipe is provided with at least one second fire sprinkler;

[0022] The fire-fighting water provided by the water supply pipe is supplied to at least one second fire-fighting sprinkler through the horizontal pipe and / or the vertical receiving pipe, so that the at least one second fire-fighting sprinkler sprays water to the bottom of the vehicle.

[0023] In some embodiments, the water supply assembly further includes an electrically controlled valve and a water supply pump, and the electrically controlled valve and the water supply pump are both disposed on the water supply pipe;

[0024] The fire monitor is electrically connected to the electric control valve and the water supply pump. When the fire monitor determines that the fire condition in the parking space is a fire, the fire monitor opens the electric control valve and the water supply pump.

[0025] In some embodiments, the fire monitor includes a temperature sensor and a gas sensor, the temperature sensor and the gas sensor are arranged on the vehicle stop body, and the gas sensor is used to detect the concentration of at least one gas among hydrogen, carbon monoxide, and volatile organic compounds;

[0026] When the temperature sensed by the temperature sensor is greater than a first threshold value, and the concentration of the gas sensed by the gas sensor is greater than a second threshold value, the fire monitor determines that a fire has occurred in the parking space.

[0027] A second embodiment of the present application provides a parking lot, comprising:

[0033] Beneficial effects of the embodiments of the present invention:

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of the present invention.

[0048] The difference between electric vehicles and traditional fuel vehicles is that the batteries of electric vehicles are usually installed in the vehicle chassis. When a fire occurs in the battery of an electric vehicle, it is difficult to control the fire in time if the battery cannot be cooled down in a timely and effective manner.

[0049] The embodiments of the present application are mainly intended to provide a parking space blocker and a parking lot, which are devices that can combine vehicle blocking functions and fire prevention and control functions. They not only need to have basic vehicle blocking functions, but also should be able to respond quickly when a fire occurs, cool the bottom of the vehicle and extinguish the fire, thereby facilitating the control of electric vehicle fires, reducing losses, and improving the safety of parking lots.

[0050] To address this issue, the inventors installed fire sprinklers on the vertical poles of parking blockers, located adjacent to the electric vehicle chassis. This effectively provides spray coverage for the underside of the vehicle. Furthermore, by integrating a fire monitor into the blocker's main body, fire detection and extinguishing actions can be triggered simultaneously. This breakthrough, transcending the traditional single-function approach of blockers, combines the physical blocker structure with a firefighting system. By utilizing the longitudinal extension of the vertical poles to arrange the sprinklers, the inventors have created a system capable of autonomously cooling and extinguishing the underside of electric vehicles.

[0051] Figure 1 This is a schematic diagram of the structure of a parking space blocker after it is deployed, provided in an embodiment of the present application. Figure 2A schematic diagram of the structure of a parked vehicle after a parking space barrier is deployed according to an embodiment of the present application is provided. Figure 1 and Figure 2 As shown, a parking space stopper includes: a stopper body 10, a water supply assembly 20 and a fire monitor 30. The stopper body 10 includes a horizontal bar 11 and a vertical bar 12. The horizontal bar 11 extends along the width direction X of the parking space and is used to limit the offside of the vehicle when entering the parking space. The vertical bar 12 is connected to the horizontal bar 11 and extends along the length direction Y of the parking space. The vertical bar 12 is provided with at least one first fire sprinkler 13; the water supply assembly 20 is used to provide fire water to at least one first fire sprinkler 13 so that at least one first fire sprinkler 13 sprays water on the bottom of the vehicle; the fire monitor 30 is provided on the stopper body 10 and is used to judge the fire condition of the parking space. The fire monitor 30 is electrically connected to the water supply assembly 20. When the fire condition of the parking space is a fire, the water supply assembly 20 provides fire water to at least one first fire sprinkler 13.

[0052] The horizontal bar 11 is a rigid structural member arranged along the width direction X of the parking space. It can be made of rubber, high-strength aluminum alloy, or stainless steel, and has excellent corrosion resistance and mechanical strength. Specifically, the horizontal bar 11 can be implemented as a hollow steel pipe or profile. It not only serves to block vehicles but also serves as a mounting support for the water supply pipe for the first fire sprinkler 13. Of course, the horizontal bar 11 can also be a rubber block, with the water supply pipe for the first fire sprinkler 13 installed on the outside of the rubber block or within a pipe channel arranged within the rubber block.

[0053] The vertical bar 12 may refer to a supporting structure extending perpendicular to the horizontal bar 11 and may be made of the same material as the horizontal bar 11. The horizontal bar 11 and the vertical bar 12 form a "T"-shaped integrated structure. The entirety of the parking block body 10 is fixed to the parking space floor via embedded components, which provides a strong sense of integrity for the parking block body 10 and ensures a stable and reliable installation. The vertical bar 12 is located between the left and right tires of the vehicle. The longitudinal extension of the vertical bar 12 enables the first fire sprinkler 13 installed thereon to cover the longitudinal depth of the vehicle chassis. When there are multiple first fire sprinklers 13, the multiple first fire sprinklers 13 are spaced apart along the extension direction of the vertical bar 12.

[0054] The first fire sprinkler 13 may be an atomizing nozzle arranged on the vertical rod 12. The water source of the water supply assembly 20 may be connected to a building fire protection pipe network or an independent water tank, and the water flow may be controlled by a solenoid valve.

[0055] The fire monitor 30 may be a detection device including integrated temperature and gas.

[0056] During application, the horizontal bar 11 is fixed at the tail end of the parking space to form a physical barrier, and the vertical bar 12 can extend along the parking direction of the vehicle to the area under the vehicle near the battery. When the vehicle is parked, the nozzle on the vertical bar 12 maintains an appropriate spraying distance from the vehicle chassis. The fire monitor 30 continuously monitors the ambient temperature and combustible gas concentration. When the detection value exceeds the preset threshold, it immediately sends a start signal to the water supply component 20. The water supply pipeline transports fire water to the nozzle, and the water flows through the nozzle and is atomized and directly acts on the bottom of the vehicle. The entire fire extinguishing process can be completed automatically when the vehicle is parked without the need for human intervention.

[0057] Compared to existing technologies, traditional car blockers only achieve passive blocking through metal structures, lacking fire detection capabilities and active fire extinguishing devices. This solution innovatively utilizes the car blocker body as a mounting platform for the firefighting system. The extended nature of the vertical rod 12 allows the first fire sprinkler 13 to cover the high-risk area under the vehicle, which is difficult for firefighters to extinguish. Compared to solutions with separate fire extinguishing devices, this design eliminates the need for additional parking space, and the structural integration of the car blocker and the firefighting system reduces equipment complexity.

[0058] The device is particularly suitable for parking lots with a high concentration of electric vehicles. It can implement precise and rapid fire extinguishing in the early stages of battery thermal runaway, facilitate cooling the bottom of electric vehicles, speed up fire extinguishing of electric vehicles, improve the safety of parking lots, and avoid secondary damage caused by the spread of fire.

[0059] In some embodiments, the vertical rod 12 includes a storage vertical pipe 121 and a water spray pipe 122, the water spray pipe 122 is retractably arranged in the storage vertical pipe 121, the water spray pipe 122 is connected to the storage vertical pipe 121, and at least one first fire sprinkler 13 is arranged in the water spray pipe 122; the water supply assembly 20 includes a water supply pipe 21, and the water supply pipe 21 is connected to the storage vertical pipe 121; under the water pressure of the fire water provided by the water supply pipe 21, the fire water enters the water spray pipe 122 through the storage vertical pipe 121, and pushes the water spray pipe 122 to extend out of the storage vertical pipe 121, and enables at least one first fire sprinkler 13 to spray water on the bottom of the vehicle.

[0060] The vertical receiving pipe 121 refers to a vertical pipe structure for accommodating the water spray pipe 122 , which can be made of metal or high-temperature resistant composite materials to play a supporting and guiding role, so that the water spray pipe 122 can be extended and retracted along a straight line.

[0061] The retractable setting of the water spray pipe 122 means that the water spray pipe 122 is nested inside the storage vertical pipe 121, which can be specifically achieved by adopting a multi-stage sleeve structure or a bellows structure. When there is no external force, it is in a retracted state, reducing the overall volume of the equipment.

[0062] The water inlet of the water supply pipe 21 is connected to the fire water pipe 40, and the fire water is sequentially delivered into the water supply pipe 21 and the water spray pipe 122 by the fire water pipe 40. The water pressure of the fire water pushes the water spray pipe 122 to extend, which refers to the mechanical thrust generated by the high-pressure water flow input by the water supply pipe 21. Specifically, it can be achieved through the pressure difference generated when the water flow enters the internal cavity of the water spray pipe 122. The automatic extension of the water spray pipe 122 can be completed without the need for an additional power device.

[0063] In the event of a fire, the water supply pipe 21 delivers high-pressure firefighting water to the storage standpipe 121. The water then flows through the standpipe 121 and into the spray pipe 122. Because the front end of the spray pipe 122 is closed and the sidewalls are equipped with first fire sprinkler heads 13, the water pressure creates a thrust at the end of the spray pipe 122, propelling it out of the storage standpipe 121 along the length direction Y of the parking space. As the spray pipe 122 extends, the multiple sprinkler heads installed on it become exposed, forming a linear spray area covering the bottom of the vehicle.

[0064] In some embodiments, the water spray pipe 122 may have a built-in spring return device. When the water pressure is maintained, the water spray pipe 122 remains in an extended state. After the water pressure is removed, the water spray pipe 122 can be returned to the storage standpipe 121 through the built-in spring return device.

[0065] This solution directly drives the water spray pipe 122 to expand and contract through water pressure, which avoids the need for an external power device and ensures the compactness of the equipment under normal conditions through the nested structure.

[0066] Through the above technical solution, the present application can maintain the structural integrity of the vehicle barrier when the vehicle is parked normally. Only in the event of a fire can the water spray pipe 122 be automatically deployed by water pressure, allowing the fire sprinkler to be precisely directed at the vehicle chassis area. The extension length of the water spray pipe 122 can be automatically adjusted according to the water pressure, for example, fully extended under high pressure conditions, ensuring that the water spray coverage area matches the vehicle size.

[0067] Figure 3 This is a schematic diagram of the structure of a parking space blocker after it is stored, provided in an embodiment of the present application. Figure 4 A schematic diagram of a structure of a parked vehicle after a parking space barrier is stored provided in an embodiment of the present application, combined with Figure 3 and Figure 4 As shown, when there is no fire in the parking space, the water spray pipe 122 can be retracted into the storage vertical pipe 121, reducing the space occupied by the parking space blocker in the length direction Y of the parking space, so as to reduce the impact of vehicles entering the parking space.

[0068] Combine Figure 1As shown, the length of the horizontal bar 11 along the parking space width direction X can be L1, the length of the storage vertical tube 121 along the parking space length direction Y can be L2, and the height of the horizontal bar 11 can be H. L1 can be between 1 meter and 2 meters, and H can be between 0.05 meter and 0.15 meter. This size range allows the horizontal bar 11 to prevent vehicles from running off the road while avoiding excessive lateral space. L2 can be between 0.5 meter and 2.5 meters. This size range allows the vertical tube to remain compact under normal conditions, providing sufficient space for extension when spraying water.

[0069] Furthermore, the water spray pipe 122 is a multi-stage telescopic nozzle, and at least one first fire sprinkler head 13 is arranged on each stage of the telescopic nozzle; under the water pressure of the fire water provided by the water supply pipe 21, each stage of the telescopic nozzle extends from the storage vertical pipe 121 along the length direction Y of the parking space.

[0070] The water spray pipe 122 adopts a multi-stage telescopic nozzle structure, and each stage of the telescopic nozzle is equipped with a fire extinguishing nozzle. When the water supply pipe 21 outputs fire water, the telescopic nozzles at each stage are extended layer by layer along the longitudinal direction of the parking space under the action of water pressure, forming a stepped extension state.

[0071] The multi-stage telescopic nozzle is a retractable pipe formed by nesting two or more pipe sections of decreasing diameter, with stoppers between adjacent sections to prevent over-extension. This structure remains compact and stowed in normal operation. In the event of a fire, it is hydraulically driven to extend in multiple stages, effectively spraying the entire vehicle chassis.

[0072] Specifically, the horizontal bar 11 is a horizontal pipe; the water supply pipe 21 is directly connected to one end of the horizontal pipe, and the storage vertical pipe 121 is directly connected to the horizontal pipe and the water spray pipe 122 respectively. The fire water provided by the water supply pipe 21 passes through the horizontal pipe, the storage vertical pipe 121 and the water spray pipe 122 in sequence to supply water to at least one first fire sprinkler 13.

[0073] The horizontal pipe has a through cavity inside to form a fire water flow channel, serving as the main water supply channel for horizontal water flow. The storage vertical pipe 121 is a vertical pipe arranged along the length direction Y of the parking space. It is used to accommodate the spray pipe 122 and guide its expansion and contraction. It also serves as a longitudinal connection between the horizontal pipe and the spray pipe 122 to ensure water flow transmission.

[0074] Specifically, the horizontal pipe and / or the vertical receiving pipe 121 is provided with at least one second fire sprinkler 14; the fire water provided by the water supply pipe 21 is supplied to the at least one second fire sprinkler 14 through at least one of the horizontal pipe and the vertical receiving pipe 121, so that the at least one second fire sprinkler 14 sprays water on the bottom of the vehicle.

[0075] When multiple second fire sprinklers 14 are installed on the transverse pipe, they are arranged along the width direction X of the parking space, covering the transverse underbody area of the vehicle. When multiple second fire sprinklers 14 are installed on the surface of the storage vertical pipe 121, they are distributed along the length direction Y of the parking space. Together with the multiple first fire sprinklers 13, they cover the longitudinal underbody area of the vehicle. After fire water is input into the transverse pipe and storage vertical pipe 121 through the water supply pipe 21, the multiple first fire sprinklers 13 and the multiple second fire sprinklers 14 together form a spatial spray network, spraying a large area under the vehicle.

[0076] Figure 5 A schematic diagram of the electrical connection structure of a parking space blocker provided in an embodiment of the present application, combined with Figure 5 As shown, the water supply component 20 also includes an electric-controlled valve 22 and a water supply pump 23, and the electric-controlled valve 22 and the water supply pump 23 are both arranged on the water supply pipe 21; the fire monitor 30 is electrically connected to the electric-controlled valve 22 and the water supply pump 23. When the fire monitor 30 determines that the fire condition of the parking space is a fire, the fire monitor 30 opens the electric-controlled valve 22 and the water supply pump 23.

[0077] The electric control valve 22 refers to a device that controls the on / off of the water channel through an electrical signal. Specifically, it can be implemented by a solenoid valve or an electric ball valve. Its function is to replace the traditional manual valve and realize the automatic opening of the water supply pipeline when a fire occurs.

[0078] The water supply pump 23 is a mechanical device used to increase water pressure. Specifically, it can be implemented as a centrifugal pump or a plunger pump. Its function is to actively build up firefighting water pressure, ensuring effective spraying from the sprinkler heads even when the external water supply pressure is insufficient. The fire monitor 30 is electrically connected to the electronically controlled valve 22 and water supply pump 23 through electrical wiring or wireless communication modules. When a fire occurs, the fire detection signal generates control instructions to open the electronically controlled valve 22 and start the water supply pump 23.

[0079] The fire monitor 30 includes a temperature sensor 31 and a gas sensor 32. The temperature sensor 31 and the gas sensor 32 are provided on the vehicle stopper body 10. The gas sensor 32 is used to detect the concentration of at least one gas selected from hydrogen, carbon monoxide, and volatile organic compounds.

[0080] When the temperature sensed by the temperature sensor 31 is greater than a first threshold (eg, 65 to 125 degrees), and the concentration of the gas sensed by the gas sensor 32 is greater than a second threshold, the fire monitor 30 determines that a fire has occurred in the parking space.

[0081] Traditional fire monitoring devices rely solely on temperature detection or single gas detection, making them susceptible to interference from vehicle exhaust, high temperatures, or sensor failures in parking lots, leading to misjudgments or missed detections. This solution uses a dual-parameter detection system, temperature and gas. When a fire occurs in a parking space, temperature sensor 31 monitors ambient temperature changes in real time, while gas sensor 32 simultaneously detects the concentration of at least one of hydrogen, carbon monoxide, and volatile organic compounds. If the temperature exceeds a first threshold and the gas concentration exceeds a second threshold, a dual-threshold triggering mechanism prevents both false triggering of temperature sensor 31 due to high ambient temperatures and false alarms of gas sensor 32 due to brief gas leaks.

[0082] In addition, the electric control valve 22 and the water supply pump 23 also have a manual operation function so as to be manually opened or closed in an emergency.

[0083] The parking space blocker of the embodiment of the present application can be widely used in places such as parking lots, charging stations, etc. Taking a parking lot as an example, the embodiment of the present application proposes a parking lot, including a parking space and a parking space blocker arranged in the parking space, and the parking space blocker adopts the parking space blocker of the above embodiment.

[0084] In the embodiments of this application, a parking blocker simultaneously blocks vehicles from crossing the road and provides fire prevention and control functions. This contrasts with existing technologies, which typically utilize separate blockers and fire sprinkler systems. These sprinkler heads are attached to the roof or walls of the building, failing to effectively cover the enclosed space beneath the vehicle. This solution integrates firefighting functionality directly into the parking blocker, positioning the first fire sprinkler head 13 on a vertical rod 12 positioned closer to the vehicle chassis. This allows for rapid and effective cooling and fire extinguishing under the vehicle, shortening firefighting response time.

[0085] Through the above technical solution, this application can monitor the fire risk in the chassis area in real time when the vehicle is parked, effectively suppressing the spread of fire caused by battery thermal runaway. The integration of parking blockers and fire protection systems reduces the space occupied by the installation of additional fire protection equipment and maintains the original layout and functional integrity of the parking lot.

[0086] Figure 6 A schematic diagram of the electrical connection structure of a parking lot provided in an embodiment of the present application, combined with Figure 6 As shown, the parking lot further includes a fire control system 100. The fire control system 100 is electrically connected to the water supply assembly 20 and the fire monitor 30. When the fire monitor 30 determines that a fire has occurred in the parking space, it sends an alarm signal to the fire control system 100, causing the fire control system 100 to control the water supply assembly 20 to supply fire water to at least one first fire sprinkler 13.

[0087] Specifically, when a fire occurs under the vehicle, the temperature sensor 31 and gas sensor 32 mounted on the parking barrier transmit detection data to the fire monitor 30. When the monitoring data exceeds a preset threshold, the fire monitor 30 sends an alarm signal to the fire control system 100 via wired or wireless communication. Upon receiving this alarm signal, the fire control system 100 automatically activates the electric valve 22 and water pump 23 on the water supply pipe 21, allowing firefighting water to be delivered through the pipe to the first fire sprinkler 13 of the parking barrier. The parking barrier of this embodiment of the present application can be integrated with the parking lot's fire control system 100, enabling coordinated control of fire detection, alarm signal transmission, and the water supply component 20.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
