Description

Technical Field

[0001] The utility model relates to the technical field of fire protection facilities, in particular to a protection device for instantaneous spatial isolation of a parking lot fire. Background Art

[0002] With the development and popularization of electric vehicles, three-dimensional garages for electric vehicle parking and charging have been gradually built, making it more convenient to use electric vehicles. However, in recent years, the number of electric vehicle fires has been increasing. According to the characteristics of lithium batteries, overcharging during the charging process is most likely to cause the battery to catch fire, and the fire spreads extremely fast, endangering the safety of the parking lot. For the preventive measures against parking lot fires, commonly, a fire isolation and protection device is set on adjacent parking spaces in the parking lot. Among them, the fire retardant curtain is a relatively common one.

[0003] Most of the existing fire retardant curtains are driven by motors to descend and retract. They cooperate with various fire detectors and lower the fire retardant curtain in the initial stage of the fire to limit the spread area. However, there are still problems such as the descending speed of the fire retardant curtain driven by the motor not being fast enough, the fire having spread over a large area when the fire retardant curtain completes the descending action, the structure of the fire retardant curtain mechanism being relatively complex, the difficulty of subsequent replacement and maintenance being relatively large, and the operation being complex and cumbersome. Content of the Utility Model

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A protection device for instantaneous spatial isolation of a parking lot fire includes a frame and a fire retardant curtain fixed on the top of adjacent parking spaces in the parking lot. The frame consists of an upper frame and a bottom plate. The bottom plate covers or is hinged to the bottom of the upper frame. The upper frame is provided with several electric control locking mechanisms for fixing the bottom plate. The bottom plate and the upper frame form a storage space for storing the fire retardant curtain. One end of the fire retardant curtain is fixedly connected to the upper frame.

[0006] Further, the electric control locking mechanism is an electromagnetic snap formed by a power-off type electromagnet.

[0007] Further, in some embodiments, the bottom plate covers the bottom of the upper frame. The fire retardant curtain is stored in the frame, and the other end of the fire retardant curtain is fixedly connected to the bottom plate. At this time, the bottom plate functions as a counterweight to increase the weight of the fire retardant curtain.

[0008] Further, the bottom plate is made of a metal material that can be magnetically adsorbed.

[0009] Further, the electromagnetic snap is arranged on the inner side wall of the upper frame. The inner side wall of the upper frame is also provided with several spring components for assisting in opening the bottom plate.

[0010] Further, in some embodiments, one end of the bottom plate is hinged to the upper frame, and the other end of the bottom plate is connected to the upper frame through an electric control locking mechanism. The fireproof curtain is wound in the frame, and a counterweight shaft is provided at the other end of the fireproof curtain.

[0011] Further, a torsion spring is provided at the end of the bottom plate hinged to the upper frame, and both ends of the torsion spring are fixedly connected to the inner side wall of the upper frame and the bottom plate respectively.

[0012] Further, one end of the fireproof curtain is detachably and fixedly connected to the upper frame through a fixing component. Specifically, in some embodiments, the fixing component is a bolt.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When the present utility model is in use, the bottom plate of the frame is opened through the electric control locking mechanism, so that the fireproof curtain quickly descends in free fall under the action of gravity. The completion time of the whole action is significantly shorter than that of the conventional fireproof curtain mechanism driven by a motor to complete the descent, greatly improving its working efficiency.

[0015] 2. The present utility model adopts a frame composed of an upper frame and a bottom plate, and an electric control locking mechanism is arranged on the upper frame to fix the bottom plate. The electric control locking mechanism is an electromagnetic suction buckle composed of a power-off type electromagnet structure. When the present utility model is in use, the electromagnetic suction buckle is electrified and instantly loses magnetism, quickly lowering the bottom plate. This opening method can complete the action of opening the frame faster than other mechanical switches, enabling the fireproof curtain to quickly descend.

[0016] 3. The structure of the present utility model can be such that the end of the fireproof curtain that drops vertically is fixedly connected to the bottom plate, and the bottom plate also functions as a counterweight block of a conventional fireproof curtain, driving the fireproof curtain to descend when the bottom plate lands when it is opened.

[0017] 4. The structure of the present utility model is simple, facilitating the daily maintenance by staff, as well as the replacement and handling after a fire. The installation and operation processes are easy, improving the working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1

[0029] Refer to Figure 1 and Figure 2, A protection device for instantaneous spatial isolation of a parking lot fire, including a frame 10 and a fireproof curtain 20 arranged between the tops of adjacent parking spaces in the parking lot. The frame 10 includes an upper frame 11 and a bottom plate 12. In this embodiment, the bottom plate 12 is preferably covered on the bottom of the upper frame 11. The upper frame 11 is provided with a plurality of electric control locking mechanisms for fixing the bottom plate 12. Specifically, in this implementation, an electromagnetic suction buckle 121 composed of a power-off type electromagnet is used as the electric control locking mechanism to fix the bottom plate 12. The electromagnetic suction buckle 121 can be arranged on the outer side wall of the upper frame 11, and a metal sheet extending to the corresponding position of the electromagnetic suction buckle 121 is arranged on the bottom plate 12. The electromagnetic suction buckle 121 adsorbs the metal sheet to achieve the effect of fixing the bottom plate 12; the electromagnetic suction buckle 121 can also be arranged on the inner side wall of the upper frame 11, and the bottom plate 12 is made of a metal material that can be magnetically adsorbed, so that the electromagnetic suction buckle 121 can directly adsorb the bottom plate 12 to achieve the fixing effect. This embodiment preferably adopts the latter. In the unpowered state, the electromagnetic suction buckle 121 has magnetism and adsorbs the bottom plate 12 covering the bottom of the upper frame 11, so that the frame 10 is in a closed state. The upper frame 11 and the bottom plate 12 form a storage space 13. In this embodiment, the fireproof curtain 20 is folded and stored in this storage space 13. In the normal state, the storage space 13 can play a good role in preserving and dust-proofing the fireproof curtain 20.

[0030] Referring to Figure 1 and Figure 2 , One end of the fireproof curtain 20 is detachably and fixedly connected to the upper frame 11. In this embodiment, a plurality of bolt assemblies 21 are used as fixing components to lock the fireproof curtain 20 and the upper frame 11. When the fireproof curtain 20 needs to be replaced, the fireproof curtain 20 is disassembled by removing the bolt assemblies 21. The falling end of the fireproof curtain 20 is fixedly connected to the bottom plate 12. When the frame 10 is opened, the bottom plate 12 falls freely and takes the fireproof curtain 20 down together. The bottom plate 12 also acts as a counterweight in a conventional fireproof curtain 20 mechanism. A plurality of spring assemblies 111 for assisting the opening of the bottom plate 12 are also arranged on the inner side wall of the upper frame 11. Specifically, a plurality of spring bases 112 are arranged on the inner side wall of the upper frame 11. One end of the spring assembly 111 is fixedly connected to the spring base 112, and the other end faces the bottom plate 12. When the frame 10 is in a closed state, the bottom plate 12 covers the bottom of the upper frame 11 and compresses the spring assembly 111, so that the spring assembly 111 is in a state of storing energy; when the frame 10 is opened, the electromagnetic suction buckle 121 is powered on and loses magnetism, releasing the bottom plate 12. At the same time, the spring assembly 111 deforms and resets, and its elastic force assists the bottom plate 12 to move downward, so that the bottom plate 12 is affected by both gravity and the elastic force of the spring assembly 111 during reset, and quickly falls downward.

[0031] Referring to Figure 3 and Figure 4, in a specific implementation, the protection device further includes a zone controller 30 provided on the parking space in the parking lot, and a smoke sensor 31, a temperature sensor 32, a sprinkler head 33, and a smoke exhaust fan 34 that are electrically connected to the zone controller 30 respectively. The zone controller 30 has functions such as receiving, analyzing, processing data, and positioning, which are conventional existing products on the market. The smoke sensor 31 and the temperature sensor 32 serve as front-end detection mechanisms to detect the status of the parking lot in real time. When the data of the parking lot detected by the smoke sensor 31 and the temperature sensor 32 exceed the set threshold, they send abnormal signals to the zone controller 30 respectively. Specifically, two smoke sensors 31, one temperature sensor 32, one sprinkler head 33, and one smoke exhaust fan 34 can be set on each parking space, and racks 10 containing fire retardant curtains 20 are provided between the tops of adjacent parking spaces. It can also be reasonably arranged according to the actual size of the site. The zone controller 30 is also electrically connected to the electric control locking mechanism in the rack 10 and can control the power-on state of the electric control locking mechanism to open the bottom plate 12 of the rack 10.

[0032] During use, the smoke sensor 31 and the temperature sensor 32 judge whether there is an abnormality in the parking lot by whether the detected values exceed the set threshold. When detection devices such as the smoke sensor 31 and the temperature sensor 32 in the parking lot sense signs of a fire in the parking lot, they send abnormal signals to the zone controller 30. The zone controller 30 analyzes and processes the received signals, controls the electric control locking mechanism of the rack 10 to start, the electromagnetic suction buckle 121 on the upper frame 11 of the rack 10 is powered on and loses magnetism, releasing the bottom plate 12. The bottom plate 12 instantaneously drops to the ground under the dual action of gravity and the restoring force of the spring assembly 111. One end of the fire retardant curtain 20 fixedly connected to the bottom plate 12 is pulled along, unfolding the fire retardant curtain 20 to isolate the fire area. The zone controller 30 then selects to control the sprinkler head 33 to open based on the received abnormal signal to extinguish the fire at the fire location, and at the same time controls the smoke exhaust fan 34 to start to blow and exhaust smoke at the fire scene. In a specific implementation, the zone controller 30 can also be electrically connected to devices such as the fire door in the parking lot and control the start and stop of these devices according to the situation.

[0033] Embodiment 2

[0034] Refer to Figure 5 and Figure 6, this embodiment has basically the same structure as Embodiment 1 and will not be elaborated here. The difference lies in that the bottom plate 12 of this embodiment is hinged to the bottom of the upper frame 11, and the free end of the bottom plate 12 is fixed to the upper frame 11 through an electromagnetic suction buckle 121 provided on the inner side wall of the upper frame 11. Several hinges or pin shafts 122 can be used as connecting components at the end where the bottom plate 12 is hinged to the upper frame 11. Several torsion springs can also be provided at the hinged end. Specifically, both ends of the torsion spring are respectively fixed to the inner side wall of the upper frame 11 and the bottom plate 12. When the frame 10 is in the closed loading state and the bottom plate 12 is closed, the torsion spring is in a compressed deformation state. When the electromagnetic suction buckle 121 is energized and loses magnetism, releasing the bottom plate 12, the torsion spring resets and expands, enabling the bottom plate 12 to be simultaneously subjected to the tension of the torsion spring reset, assisting the bottom plate 12 to quickly open.

[0035] Referring to Figure 5 and Figure 6 , the fire-proof curtain 20 of this embodiment is wound in the storage space 13 inside the frame 10, and a counterweight shaft 22 is provided at one end where the fire-proof curtain 20 naturally hangs down, which can increase the gravity received by the fire-proof curtain 20. When the area controller 30 controls the electromagnetic suction buckle 121 to be energized and opens the bottom plate 12, the counterweight shaft 22 rolls to the ground under the action of gravity, unfolds the fire-proof curtain 20, and isolates the fire occurrence area.

[0036] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
