DETAILED DESCRIPTION

[0030] The following will be combined with the 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 without making creative efforts are within the scope of protection of the present invention.

[0031] The purpose of this utility model is to provide a fire isolation device and a new energy vehicle parking space fire protection system to solve the problems existing in the above-mentioned prior art, so as to achieve the goal of isolating the fire point when a fire occurs, preventing adjacent flammable materials from being ignited, and preventing the fire from spreading.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] like Figures 1 to 8As shown, this embodiment provides a fire isolation device, including a horizontally extending protective shell 2 and a fireproof cloth 4 collected in the protective shell 2. Preferably, the protective shell 2 is installed on one side or the outer peripheral side of the flammable equipment by hoisting; one end of the fireproof cloth 4 is connected to the inner top wall of the protective shell 2, and the other end is connected to a limit rod 5 extending in the same direction as the protective shell 2; the protective shell 2 is provided with through holes at both ends along its extension direction for the two ends of the limit rod 5 to extend respectively, and the bottom end of the protective shell 2 is provided with a strip opening for releasing the limit rod 5 and the fireproof cloth 4, and the strip opening is in the same direction as the protective shell 2 The protective shell 2 extends in the direction of extension and passes through the protective shell 2; the protective shell 2 is provided with a locking end cover 6 on the outer side of both ends along the extension direction, one end of the locking end cover 6 is hinged at the top position of the through hole, and the other end extends downward to the position of the strip opening, at least one locking end cover 6 can be popped open in the direction away from the through hole, and a fireproof rope 10 that can be disconnected is connected between the ends of the strip openings corresponding to the two locking end covers 6. The fireproof rope 10 tightens the two locking end covers 6 for fixing them to the two ends of the limit rod 5. Preferably, the fireproof rope 10 tightens the two locking end covers 6 so that the two locking end covers 6 are respectively pressed against the two ends of the limit rod 5. Through the fire isolation device 1 disclosed by the present invention, when no fire occurs, the locking end cover 6 is in a locked state. Under the tension of the fireproof rope 10, the two locking end covers 6 are pressed against the two ends of the limit rod 5 to form a stable locking structure, so that the limit rod 5 with the fireproof cloth 4 is stored in the protective shell 2. When a fire occurs, the fireproof rope 10 is disconnected, the locking structure is destroyed, and at least one locking end cover 6 bounces open in the opposite direction away from the through hole, so that the limit rod 5 is in an unlocked state. The limit rod 5 and the fireproof cloth 4 release the strip opening under the action of gravity and unfold, forming a fireproof isolation barrier at the fire point to isolate the fire point and prevent the fire from spreading.

[0034] In this specific embodiment, both locking end covers 6 can pop open, and after the fire rope 10 is disconnected, the two locking end covers 6 pop open synchronously to release the limiting rod 5, and then the fireproof cloth 4 and the limiting rod 5 fall through the strip opening synchronously, and the fireproof cloth 4 is unfolded; or one locking end cover 6 can pop open, and the position of the other locking end cover 6 is fixed, so that after the fire rope 10 is disconnected, one locking end cover 6 pops open, and the other locking end cover 6 remains stationary, which can also release the limiting rod 5, and then the fireproof cloth 4 and the limiting rod 5 fall through the strip opening synchronously, and the fireproof cloth 4 is unfolded.

[0035] In a specific embodiment, the fireproof cloth 4 is wound or stacked on the limiting rod 5. No matter whether the fireproof cloth 4 is wound on the limiting rod 5 or stacked on the limiting rod 5, after the locking end cover 6 pops open, the width of the strip opening can release the wound or stacked fireproof cloth 4 as a whole, and the fireproof cloth 4 passing through the strip opening can be unfolded as a whole.

[0036] In one embodiment, the fire rope 10 includes a plurality of sequentially connected connecting segments and at least one disconnection mechanism 9 that is disconnected by temperature control or electrical signal control. The disconnection mechanism 9 is connected between two corresponding adjacent connecting segments. When the ignition point temperature reaches a predetermined value, the disconnection mechanism 9 melts or disconnects upon receiving a corresponding electrical signal, causing the entire fire rope 10 to disconnect and thereby causing the locking end cap 6 to spring open. Preferably, a disconnection mechanism 9 is connected between each adjacent connecting segment to fully ensure that the entire fire rope 10 can be fully disconnected under predetermined conditions. Preferably, the electrical signal includes a smoke sensor signal, a temperature sensor signal, a pressure sensor signal, an infrared sensor signal, an image recognition signal, and a central control signal, so that the disconnection mechanism 9 can disconnect under the conditions of various electrical signals, effectively ensuring that the entire fire rope 10 is in a disconnected state after a fire occurs.

[0037] The temperature-controlled separation mechanism 9 is composed of two or more connecting pieces welded together by a hot-melt alloy. When the ignition temperature reaches the melting temperature set for the hot-melt alloy, the hot-melt alloy melts and the connecting pieces separate, thereby realizing the separation action of the separation mechanism 9. The separation action of the temperature-controlled separation mechanism 9 can also be controlled by other heat-sensitive components, such as a temperature memory alloy or a temperature-sensitive glass ball. At room temperature, the temperature memory alloy, the temperature-sensitive glass ball and other auxiliary accessories form a stable connection structure. When the ignition temperature reaches the set value, the temperature memory alloy deforms or the temperature-sensitive glass ball breaks, causing the stable connection structure to become unstable and disintegrate and separate, thereby realizing the separation action of the separation mechanism 9.

[0038] The separation mechanism 9 is controlled by a motor and an electromagnet controlled by an electrical signal. At room temperature, the positioning structure or the magnetic attraction structure connected to the motor puts the separation mechanism 9 in a locked state. When the electrical signal is received, the motor is activated and the electromagnet is magnetized or demagnetized to release the locked state, thereby realizing the separation action of the separation mechanism 9.

[0039] Preferably, a plurality of separation mechanisms 9 of various types are provided on the same fireproof rope 10, and each separation mechanism 9 is respectively connected between two adjacent connecting sections. A plurality of separation mechanisms 9 are designed to be connected in series, which ensures that when a temperature-sensitive separation mechanism 9 is used, no matter the fire occurs in the front, middle or rear of the vehicle, the fireproof cloth 4 can be unlocked and released in the shortest time to effectively block the fire. At the same time, a signal separation mechanism 9 is used to achieve multiple protections, which avoids the failure of the separation mechanism 9 to release the fireproof cloth 4 to the greatest extent.

[0040] In a specific embodiment, one end of the fireproof rope 10 is fixed on a locking end cover 6, and the other end is connected to a safety pin 7 for manual unlocking. The safety pin 7 is detachable and plugged into the other locking end cover 6. Under normal conditions, the fireproof cloth 4 is stored in the protective shell 2, and the two locking end covers 6 are in a locked state and clamp the limit rod 5. When the safety pin 7 is pulled out, the locking end cover 6 is in an unlocked state and pops open to the side away from the protective shell 2. The fireproof cloth 4 is released and unfolded vertically to the ground, so that the entire fireproof rope 10 is disconnected by manually pulling out the safety pin 7, so that the entire fireproof rope 10 has both a preset disconnected state and can be disconnected manually.

[0041] In a specific embodiment, an adjustment mechanism 8 for adjusting the tension of the fire-proof rope 10 is connected between the end of the fire-proof rope 10 that is not connected to the safety pin 7 and the corresponding locking end cover 6. The preferred adjustment mechanism 8 uses a tensioning adjustment bolt, one end of the tensioning adjustment bolt is connected to the fire-proof rope 10, and the other end is connected to the corresponding locking end cover 6.

[0042] In one embodiment, two thermal hoods 3 are connected to the outer surface of the protective housing 2. The thermal hoods 3 are arranged on either side of the strip-shaped opening in a direction perpendicular to the extension of the protective housing 2. The thermal hoods 3 ensure that the protective housing 2 quickly reaches a predetermined temperature. This ensures that when a temperature-sensitive separation mechanism 9 is employed, the separation mechanism 9 can be promptly separated, unlocking and releasing the fireproof cloth 4 in the shortest possible time to effectively block the fire. The thermal hoods 3 can be either part of the protective housing 2 or removably mounted on the protective housing 2. Preferably, the thermal hoods 3 extend in the same direction as the protective housing 2 and match the extended length of the protective housing 2.

[0043] In a specific embodiment, at least one locking end cover 6 is provided with a slope for supporting the limit rod 5. The slope is located on the inner wall of the locking end cover 6 close to the limit rod 5, and the slope gradually tilts downward in the direction close to the through hole, so that after the fire rope 10 is disconnected, the locking end cover 6 no longer clamps the limit rod 5. The limit rod 5 moves downward under the action of its own weight and the fireproof cloth 4. The two ends of the limit rod 5 slide along the slope and push the locking end cover 6 away from the protective shell 2, so that the limit rod 5 and the fireproof cloth 4 can quickly pass through the strip opening and unfold.

[0044] In a specific embodiment, at least one locking end cover 6 is connected to a rotating shaft installed at the top position of the through hole, and a torsion spring is provided at the rotating shaft for popping open the locking end cover 6, so that after the fire rope 10 is disconnected, the locking end cover 6 no longer clamps the limit rod 5, and under the action of the torsion spring, the locking end cover 6 rotates open in the direction away from the protective shell 2, and the limit rod 5 moves downward under the action of its own weight and the fireproof cloth 4, so that the limit rod 5 and the fireproof cloth 4 quickly pass through the strip opening and unfold.

[0045] Furthermore, a new energy vehicle parking space fire protection system is provided, comprising at least one group of fire isolation devices 1, preferably four groups. The protective shells 2 of each fire isolation device 1 are hoisted on the building roof above the parking space 16. The two protective shells 2 are respectively installed at the two long sides of the parking space 16 and extend along the long side direction of the parking space 16. The other two protective shells 2 are respectively installed at the two short sides of the parking space 16 and extend along the short side direction of the parking space 16. To match different parking spaces 16, the protective shells 2 are in the form of long strips with a length of 1m to 18m, a width of 5cm to 25cm, and a height of 5cm to 35cm. It can meet the requirements of parking spaces of different sizes such as cars and buses, and is preferably used in a parking lot with a group of fire isolation devices 1 set between two adjacent parking spaces 16. When a fire occurs in the new energy vehicle 17 in the parking space 16, the fireproof rope 10 of each fire isolation device 1 is disconnected under manual or induction conditions, causing the locking end cover 6 to pop open, and then the limit rod 5 and the fireproof cloth 4 are released from the strip opening and unfolded vertically to the ground. Each fireproof cloth 4 surrounds to form a relatively independent fire isolation space, thereby isolating the new energy vehicle 17 in a burning state and preventing the fire from spreading.

[0046] In a specific embodiment, the protective shell 2 is equipped with a lifting assembly 11, which includes a load-bearing beam 12, a sliding ring 13, a sliding ring fastening pin 14, and a top plate hanging rod 15. The load-bearing beam 12 is connected to the sliding ring 13, and the sliding ring 13 is installed on the roof of the building through the top plate hanging rod 15. The protective shell 2 is set between the building roof and the ground above the edge of the parking space 16 through the load-bearing beam 12. The preferred protective shell 2 is detachably mounted on the load-bearing beam 12, and the locking end cover 6 can be hinged at the top position of the through holes at both ends of the protective shell 2, or can be hinged to the load-bearing beam 12.
