Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of fire fighting technology for electric vehicles, and in particular to an electric vehicle parking station that can be used for fire fighting. Background Technology
[0002] Major fires caused by electric bicycles are occurring frequently, resulting in significant losses of life and property. Electric bicycle fires are characterized by their sporadic and rapid spread; without effective control measures, the fire can quickly escalate.
[0003] In the event of a fire in an existing electric bicycle charging shed, water spraying is generally used for extinguishing. For example, CN2022211343062 discloses "an intelligent detection-based automatic fire extinguishing device for electric bicycle sheds." During use, a system controller enables overall control of the system. Two cable-type fire detectors are connected via cables, and the two detectors use both infrared and visible light detection for dual monitoring. Visible light detection observes the visible light emitted during combustion to determine if an electric bicycle is on fire. This allows for precise location of the burning electric bicycle, enabling accurate extinguishing of areas with excessively high temperatures or flames. The two cable-type fire detectors issue audible and visual alarms, and simultaneously, a monitoring camera pushes information and video to a mobile phone. The system controller then cuts off the power supply to the electric bicycle shed's sockets and controls the corresponding fire extinguishing structures. Fire extinguishing foam is sprayed through nozzles to the corresponding fire location for extinguishing. Summary of the Invention
[0004] This utility model provides an electric vehicle parking station with a storage chamber for storing granular fire extinguishing material. The storage chamber has an openable or closable discharge port. In the event of a fire, the discharge port can be opened to release the granular fire extinguishing material for fire suppression. After the fire is extinguished, the discharge port can be closed to return the granular fire extinguishing material to the storage chamber. The granular fire extinguishing material can be reused.
[0005] The electric vehicle parking station provided by this utility model includes an upper storage chamber and a lower parking room, separated by a partition. The storage chamber is used to store granular fire extinguishing material. The partition is provided with a discharge port, and an opening and closing device is installed at the discharge port. The opening and closing device includes a sliding plate with a through hole, located above the partition. The sliding plate can move on the partition under the drive of a driving device, so that the through hole is aligned or misaligned with the discharge port, thereby opening or closing the discharge port. When a fire occurs in the parking room, the opening and closing device opens the discharge port, and the granular fire extinguishing material falls into the parking room to extinguish the fire.
[0006] Preferably, rollers are provided on both sides of the sliding plate, and slide rails adapted to the rollers are provided on both sides of the partition plate, and the rollers move along the slide rails.
[0007] Preferably, the sliding plate is provided with multiple rows of through holes, the partition plate is provided with multiple rows of feed ports, and triangular guides are provided between adjacent rows of through holes.
[0008] Preferably, the storage cavity and the parking room form a box-like structure. The parking room is an enclosed space with one or more automatic roller shutter doors on its four walls. These automatic roller shutter doors and their opening / closing mechanisms are connected to a controller. This box-like structure facilitates the installation of electric vehicle parking stations, requiring only a suitable space. The parking station is isolated from surrounding buildings, preventing a fire from spreading to nearby structures. In the event of a fire at the parking station, closing the automatic roller shutter doors isolates the fire source from the air, resulting in effective fire suppression and enhanced safety.
[0009] Preferably, a fire monitoring device connected to the controller is installed in the parking room; the fire monitoring device is used to monitor whether there is a fire in the parking room and send a signal to the controller, the controller controls the automatic roller shutter door to close, and controls the opening and closing device to open the unloading port.
[0010] Preferably, a grating detection device connected to the controller is installed at the automatic roller shutter door to detect whether there is an object obstructing the closing of the automatic roller shutter door. If an object is found, the controller will activate the alarm. The alarm serves as a reminder to electric vehicle users to park their vehicles indoors. Alternatively, the alarm can be installed in the property management office to remind property management personnel to strengthen management.
[0011] Preferably, the storage cavity is funnel-shaped or trumpet-shaped, wider at the top and narrower at the bottom.
[0012] Preferably, the storage cavity is provided with a top cover to seal the storage cavity and prevent rainwater from entering the storage cavity and leaking into the parking room, thus wetting the electric bicycle. A charging device for charging the electric vehicle is installed in the parking room.
[0013] Preferably, the granular fire extinguishing material is sand, gravel, perlite, or vitrified microspheres, which are commonly used granular fire extinguishing materials that can be reused.
[0014] Preferably, the driving device is a drive push rod.
[0015] This utility model provides an electric vehicle parking station where electric bicycles are placed inside a housing. The housing is divided into an upper storage chamber and a lower parking room by a partition. The storage chamber stores granular fire extinguishing material, while the parking room stores the electric bicycles. The partition has a discharge port equipped with an opening and closing device. At least one electric roller shutter door is installed on the side wall of the parking room. In the event of a fire involving an electric bicycle, the roller shutter door is first closed to isolate the fire source and create a sealed enclosure, preventing air from entering. Then, the closing device is opened, and the granular fire extinguishing material covers the fire source to extinguish it. Closing the roller shutter door before covering with the fire extinguishing material improves the effect, creating a relatively enclosed space that prevents large amounts of air from entering and also prevents the fire extinguishing material from escaping, resulting in a thicker covering. The fire extinguishing material of this utility model is reusable. The opening and closing device uses a push-pull type staggered hole structure, resulting in a shorter stroke, faster opening and closing speed, and evenly distributed through holes and discharge holes for more uniform material distribution.

Detailed Implementation
[0022] Example 1:
[0023] like Figure 1-3As shown, this utility model includes a housing 1, the main body of which is made of metal or other non-flammable materials. A partition 2 is installed inside the housing 1, mounted on a crossbeam. The partition divides the inner cavity of the housing into upper and lower layers; the upper layer is a storage chamber, and the lower layer is a parking chamber. The storage chamber is used to store granular fire extinguishing materials, such as sand, gravel, perlite, and vitrified microspheres. Dry powder is a powder, not the granular fire extinguishing material described in this embodiment. A discharge port is provided on the partition 2, and an opening and closing device 3 is installed at the discharge port. This device can connect or isolate the upper and lower layers. Under normal circumstances, the opening and closing device 3 is closed, sealing the discharge port. When fire extinguishing is needed, the opening and closing device is opened, and the granular fire extinguishing material falls through the discharge port into the parking chamber to extinguish the fire on the electric vehicle in the parking chamber. The size of the storage cavity for storing granular fire extinguishing materials is related to the size of the parking room. A larger parking room can accommodate more electric vehicles, so the storage cavity needs to be larger or deeper to store more granular fire extinguishing materials. Those skilled in the art can adjust the size of the storage cavity according to actual needs, as long as it can cover the fire location. The storage cavity can be made deeper in the vertical direction to store more granular fire extinguishing materials, which can be achieved without creative effort.
[0024] At least one of the four side walls of the parking compartment is equipped with an automatic roller shutter door 4, such as an electric roller shutter door. This can be achieved by installing an electric roller shutter door on one side wall and sealing the other three, or by installing an electric roller shutter door on two side walls and sealing the other two, or by installing an electric roller shutter door on three side walls and sealing the other one, or by installing electric roller shutter doors on all four side walls. The roller shutter door material must be fire-resistant. Under normal circumstances, when the roller shutter door is open, electric vehicles can freely enter and exit. The parking compartment is equipped with a fire detection device 5, such as a smoke sensor or a surveillance camera. The fire detection device 5, the automatic roller shutter door 4, the opening and closing device 3, and the controller (not shown in the diagram) are connected.
[0025] The specific working principle is as follows: When an electric vehicle catches fire in the parking compartment, the fire monitoring device 5 detects the fire and sends a signal to the controller. The controller first controls the automatic roller shutter door to close, sealing the parking compartment and preventing the fire from spreading to the sides, as well as reducing the amount of air entering. After the roller shutter door is completely closed, the opening and closing device is activated, and the discharge port opens. The granular fire extinguishing material stored in the storage chamber falls into the parking compartment through the discharge port. The granular fire extinguishing material covers the fire source, achieving the purpose of extinguishing the fire. After all the fire extinguishing material has fallen into the parking compartment, the opening and closing device is closed. The automatic roller shutter door and the opening and closing device can also work simultaneously, but the fire extinguishing effect is not as good as closing the roller shutter door first.
[0026] A light grating detection device 6 is installed at the roller shutter door to detect whether electric vehicles obstruct the closing of the roller shutter door. An audible and visual alarm (not shown in the diagram) is installed on the housing. The light grating detection device 6 and the audible and visual alarm are connected to the controller. When the light grating detection device continuously detects information within a set time, the controller activates the audible and visual alarm to remind people not to place electric bicycles at the roller shutter door and to place them properly. The audible and visual alarm turns off after the light grating detection device signal disappears. In the event of a fire, the controller can also activate the audible and visual alarm. The audible and visual alarm can also be installed in the property management office to remind property staff to strengthen management.
[0027] like Figure 2 , 4 As shown in Figure 5, the opening and closing device 3 includes a sliding plate 3.1 slidably mounted above the partition 2, and a drive push rod 3.2 mounted on the housing or partition 2 to drive the sliding plate 3.1 to move. The sliding plate 3.1 has a through hole 3.3 that matches the discharge port on the partition 2. The drive push rod 3.2 can drive the sliding plate 3.1 to align the through hole 3.3 on the sliding plate with the discharge port on the partition 2, forming a discharge channel, thereby opening the discharge port; or it can misalign the through hole 3.3 with the discharge port, i.e., the sliding plate blocks the discharge port. Specifically, the sliding structure of the sliding plate 3.1 consists of rollers 3.4 mounted on both sides of the sliding plate 3.1, and slide rails 3.5 matching the rollers 3.4 mounted on both sides of the partition 2, so that the drive push rod 3.2 drives the sliding plate 3.1 to move back along the slide rails 3.5. It is foreseeable that the sliding structure can also adopt a sliding groove and slider cooperation structure, a guide rail and slider cooperation structure, etc. A triangular guide 3.6 is provided between every two rows of through holes 3.3 on the sliding plate 3.1 to guide the extinguishing material to the through holes 3.3. The figure shows that the discharge port on the partition is a series of neatly arranged round holes in multiple rows; correspondingly, the through holes 3.3 on the sliding plate 3.1 are also round holes, with both the discharge port and the through holes evenly distributed. If the box is large and the partition is long, the sliding plate 3.1 can be segmented, i.e., as shown... Figure 5 As shown in the figure, two sliding plates 3.1 are set, one on the left and one on the right, and each sliding plate is driven by a drive push rod. The drive push rod can be driven by a cylinder, motor or other mechanism.
[0028] To facilitate the falling of granular fire extinguishing material into the storage compartment, the compartment is designed in a funnel or trumpet shape, wider at the top and narrower at the bottom. A top cover 7 is installed on the top of the storage compartment to prevent rainwater from entering and leaking into the parking compartment, thus wetting the electric vehicles. A charging device can also be installed inside the parking compartment for charging the electric vehicles.
