[0079] The parking space fire prevention device of the present application is designed for fire prevention of automobile parking spaces and is used for isolating new energy vehicles when a fire occurs. The new energy vehicle in which a fire occurs is isolated by an isolation method, thereby effectively preventing the fire from spreading and expanding the loss.

[0080] In addition, the parking space fire protection device is also equipped with a sprinkler pipe connected to the water network inside the parking garage. The sprinkler pipe can extend into the bottom of the new energy vehicle where a fire occurs, thereby spraying and cooling the new energy vehicle, playing a role in cooling and extinguishing the fire to a certain extent.

[0081] Example 1

[0082] like Figure 1-Figure 3 and Fig.11 The present embodiment provides a parking space fire prevention device, which includes a lower plate body 1, an upper plate body 2, a telescopic folding mechanism 3 and a fireproof cloth 4. The length direction of the upper plate body 2 or the lower plate body 1 is defined as a first direction, and the width direction is defined as a second direction. The upper plate body 2 is correspondingly arranged directly above the lower plate body 1. The telescopic folding mechanism 3 is connected between the upper plate body 2 and the lower plate body 1. The telescopic folding mechanism 3 is used to adjust the distance between the upper plate body 2 and the lower plate body 1.

[0083] The fireproof cloth 4 is arranged on one side of the telescopic folding mechanism 3, or the fireproof cloth 4 is arranged on both sides of the telescopic folding mechanism 3, and the top and bottom ends of the fireproof cloth 4 are respectively connected to the upper plate body 2 and the lower plate body 1.

[0084] The fireproof cloth 4 is stored between the upper plate body 2 and the lower plate body 1 in a stacked or rolled manner. When the upper plate body 2 and the lower plate body 1 are relatively lifted or lowered, the upper and lower ends of the fireproof cloth 4 are respectively driven to move and open. When the fireproof cloth 4 is opened to a set height (the set height is designed based on the maximum height of the vehicle body as a reference, and generally needs to be higher than the maximum height of the vehicle body), an isolation fireproof cloth wall is formed on each parking line of the parking space. Each parking space is surrounded by multiple fireproof cloth walls to form an isolated fireproof space, thereby isolating the vehicle on fire to prevent the fire from spreading and expanding losses.

[0085] It also includes a fire sensor and a controller. The fire sensor and the telescopic unit 304 are electrically connected to the controller respectively. The fire sensor is used to detect whether a fire occurs in the parking space. The fire sensor can be set in the parking space, or in the fire prevention device, or on the top of the parking space. Multiple fire sensors can also be set to achieve multi-point sensing. The controller can be installed in the fire prevention device or near the parking space, and can be flexibly installed according to needs.

[0086] During actual installation, the lower plate 1 is set corresponding to the rectangular parking line of the car parking space, and the device is set corresponding to one side of the parking line. Specifically, the lower plate 1 can be set on the top of the corresponding parking line to form a "ground design", and the lower plate 1 and the ground can be detachably connected by bolts; or, a rectangular ground groove can be dug at the corresponding parking line, so that the device is embedded in the rectangular ground groove as a whole, forming an "embedded design", and the rectangular ground groove can be dug according to the overall height of the device in the folded state, and the depth of the device embedded in the rectangular ground groove can be designed according to needs.

[0087] A first enclosure 101 may be provided on the four sides of the lower plate 1, and a second enclosure 201 may be provided on the four sides of the upper plate 2. When the device is in a folded state, the telescopic folding mechanism 3 and the fireproof cloth 4 are hidden in the first enclosure 101 and the second enclosure 201. A fluorescent coating or a reflective coating may also be provided on the top surface of the upper plate 2, such as by pasting a reflective film or a fluorescent film, or by painting a reflective paint or a fluorescent paint, so that the driver of the car can easily capture the distance information of the parking space edge when parking, so as to park safely in the parking space. When the above-mentioned "ground design" is adopted, not only a fluorescent coating or a reflective coating may be provided on the top surface of the upper plate 2, but also a fluorescent coating or a reflective coating may be provided on the periphery of the first enclosure and the second enclosure, so as to increase the fluorescent area or the reflective area, so as to facilitate the driver of the car to capture the parking space edge information in time. It should also be noted that when the device is completely embedded in the rectangular floor groove as a whole, it is a hidden design. When the car is parked, it can be directly driven over it, which is more convenient for parking. At the same time, a number of induction sensors and alarm devices for detecting whether there are objects on it can be set on the top of the upper plate body 2. The induction sensors and the alarm devices are electrically connected to the controller respectively. The induction sensors can be selected from infrared sensors, photoelectric sensors or proximity switches, etc., and the alarm devices can be selected from sound and light alarms. When the induction sensor detects that there is an object directly above it (it may be that the car is parked directly above the fire protection device), it may affect the normal expansion of the telescopic and folding mechanism 3, and thus send an alarm signal to the controller. The controller controls the sound and light alarm to send out a sound and light alarm, so as to promptly remind the car driver that he has not parked the car correctly or in a standard parking space. This can also facilitate the driver to park the car correctly in the parking space, play a role in supervision and urging, and is also conducive to more civilized parking. When the driver receives the alarm information but fails to park the car correctly and in time, the sound and light alarm can continue to send out alarm signals, and the controller can control the telescopic and folding mechanism 3 to stop working permanently until the sound and light alarm stops alarming. In addition, the parking space is a private parking space, and it can also be bound to the driver's mobile phone number or WeChat number to establish a connection. When the alarm device is in alarm mode all the time or is still in alarm mode after timing out within the set time, it will send a message or call the car owner to remind him again; the above-mentioned set time can be ten minutes, twenty minutes, etc., which is designed according to specific needs.

The two ends of the telescopic unit 304 can be respectively hinged to the upper support rod 302 and the lower support rod 301 through hinges. It should be noted that when the telescopic folding mechanism 3 is in operation, the upper support rod 302, the electric push rod and the lower support rod 301 all rotate around the second direction.

[0091] Preferably, the fireproof cloth 4 is respectively arranged on both sides of the telescopic folding mechanism 3, so that when the telescopic folding assembly is in the open state, double-sided fire protection can be performed through the fireproof cloth 4 on both sides. An upper reel and a lower reel 401 are respectively arranged at the top and bottom ends of the fireproof cloth 4, the lower reel 401 is installed on the top of the lower plate body 1, and the upper reel is installed on the bottom of the upper plate body 2.

[0092] When the fire sensor senses a fire in the parking space, the controller controls the two telescopic units 304 to operate synchronously to drive the two connecting rod assemblies to expand simultaneously, thereby driving the fireproof cloth 4 to expand, thereby blocking and protecting the fire in the parking space.

Preferably, the lock base assembly 52 and the electric lock tongue assembly 51 are respectively arranged on the top of the two cross beams 303, and the lock base assembly 52 also includes a pad 522. The lock plate 521 is arranged on the top of the second cross beam 3032 through the pad 522. The pad 522 can not only raise the height of the lock plate 521, so that the lock tongue insertion hole 5211 of the lock plate 521 corresponds to the lock tongue 514 hole and is at the same height, but also ensure the stability of the installation of the lock plate 521. The locking assembly 5 is specifically as follows Figure 7 and Figure 8 shown.

[0099] The transmission assembly 513 may be a gear assembly (gear transmission) or a pulley assembly (belt transmission), and in the present embodiment, the transmission assembly 513 is a gear assembly, the gear assembly includes a driving gear 5131 and a driven gear 5132 that are meshed and connected, the output shaft end of the motor 510 is connected to the driving gear 5131, and a rotating rod 516 is arranged on the side of the driven gear 5132 away from the upper motor 510, and the rotating rod 516 is coaxial with the driven gear 5132. The electric bolt assembly 51 also includes a bolt box 515, the bolt 514 is located in the bolt box 515, the rotating rod 516 penetrates the bolt box 515 and is connected to the bolt 514, the rotating rod 516 and the bolt 514 can be connected by a spring, the bolt 514 is in an extended state at the initial position, and then inserted into the bolt insertion hole 5211 for locking, and the bolt 514 can be pulled to retract and exit the bolt insertion hole 5211 by the rotation of the motor 510, thereby controlling the retraction of the bolt 514. When the fire protection device is in its initial state, it is in a folded state (such as Figure 1 As shown in FIG. 1 , when the telescopic folding mechanism 3 needs to be opened, the motor 510 controls the lock tongue 514 to exit the lock tongue insertion hole 5211, canceling the locking mode, and at the same time, the two beams 303 move relative to each other until they are fully opened. Fig.10 The structure shown.

[0100] Key technical points of this application:

[0101] (1) A push-pull fireproof cloth 4 is installed and fixed on the ground, and can be manually folded up and used multiple times.

[0102] (2) It does not generate additional floor space and does not affect the normal entry and exit of vehicles into parking spaces. The shell structure is strong and reliable, and is made of aluminum alloy. Even if it is accidentally run over by a vehicle, it will not affect subsequent use.

[0103] (3) The device is initially locked in a folded state by the locking assembly 5. After the fire sensor senses a danger signal, the controller opens the locking structure and the telescopic unit 304 pushes the fireproof cloth 4 to unfold.

[0104] (4) Semi-enclosed or fully enclosed protection scheme to protect vehicles around the dangerous vehicle from the spread of high-temperature fire.

[0105] (5) The size of the 4 ground-pull fireproof cloth units is adapted to the current parking space size, with 2 deployed on the side and 1 deployed on the back.

[0106] The fire prevention device is used to automatically pop out the fireproof cloth 4 structure when a fire is sensed, and provide semi-enclosed or fully enclosed protection measures for vehicles in danger to prevent the fire from spreading to other parking spaces.

[0107] The present solution is preferably designed as follows: a plurality of ground-pull fireproof cloths 4 are used to provide semi-enclosed protection for the parking space, such as Figure 1 , Fig. 9 and Fig.10 As shown, the overall effect of the ground-pull fireproof cloth 4 being folded and slowly opened is presented. Each ground-pull fireproof cloth 4 is fixed to the parking line on the ground by bolts. The width of each device is 200mm (equivalent to the width of the parking line), and it will not occupy additional area; the length is 2500mm, and the standard parking space is generally 2500*5000mm. When used, two ground-pull fireproof cloths 4 are deployed on each side, and one ground-pull fireproof cloth 4 is deployed on the back. The unfolded height of the fireproof cloth 4 is 1500mm, which can effectively isolate and protect common new energy vehicles from thermal runaway.

[0108] Example 3

[0109] This embodiment provides another parking space fire prevention device. The difference between this embodiment and embodiment 1 or embodiment 2 is that the telescopic folding mechanism 3 of this embodiment adopts a lifting mechanism, and a plurality of synchronously operated lifting mechanisms are connected between the upper plate body 2 and the lower plate body 1 to jointly lift the upper plate body 2. The lifting mechanism can adopt an electric push rod or a hydraulic rod.

[0110] Example 4

[0111] like Figures 18 to 22 As shown, a parking space fire prevention device of this embodiment is different from embodiments 1 to 3 in that the parking space fire prevention device is connected to an existing water network (not shown in the figure) in a garage (such as an underground parking lot, a ground parking room or a multi-story parking garage, etc.). When a fire is detected in a new energy vehicle on the corresponding parking space, the parking space fire prevention device opens to isolate the new energy vehicle on fire, and supplies water to the parking space fire prevention device through the water network, and sprays water on the corresponding new energy vehicle on fire through the parking space fire prevention device, thereby spraying and cooling the bottom of the vehicle.

[0112] Specifically, a spray device is provided on the inner side of the lower plate body 1 of the present embodiment, and both ends of the spray pipe 63 extend along the first direction, i.e., the length direction of the lower plate body 1. The spray device includes a fixed plate 61, a rotating plate 62, and a spray pipe 63. The fixed plate 61 is fixedly mounted on the inner side of the lower plate body 1, and one end of the rotating plate 62 is hinged to the outer end of the fixed plate 61. The spray pipe 63 is a hose and is arranged on the top surface of the fixed plate 61 and the rotating plate 62. The spray pipe 63 is connected to the water network and a plurality of water outlet holes 631 are provided on the top of the portion of the spray pipe 63 mounted on the rotating plate 62, so as to facilitate water spraying from bottom to top toward the bottom of the burning car through the spray pipe 63 to cool it down.

[0113] Further, in the initial state, the fixed plate 61 and the rotating plate 62 are on the same straight line, that is, both ends of the fixed plate 61 and the rotating plate 62 extend along the first direction (i.e., parallel to the length direction of the lower plate body 1), and the spray pipes 63 are sequentially arranged on the fixed plate 61 and the rotating plate 62. The fixed plate 61 is fixedly mounted on the inner side of the lower plate body 1, and the opposite ends of the fixed plate 61 and the rotating plate 62 are hinged by a spring, and the rotating plate 62 is also fixedly mounted on the inner side of the lower plate body 1 by a mechanical switch or a magnetic switch (not shown in the figure).

[0114] When a fire is detected, the fireproof cloth 4 is unfolded to form an isolation space for isolating the burning vehicle. After the mechanical switch or the magnetic switch is turned on, the rotating plate 62 drives the spray pipe 63 to rotate 90° toward the bottom of the burning vehicle under the action of the spring force. At the same time, the water network starts to supply water to the spray pipe 63 and sprays water through the spray pipe 63 toward the bottom of the burning vehicle to cool it down.

[0115] Since mechanical switches and magnetic switches belong to the prior art, structures such as clamping cylinders or electromagnets can be used to clamp and release the rotating plate 62, and the specific structure will not be described in detail here.

[0116] In order to prevent the spray pipe 63 from bending during the rotation process and reducing the fluidity of the water inside the spray pipe 63, the top of the hinge point 64 can be set to be higher than the fixed plate 61 and the rotating plate 62 by a certain height. When the spray pipe 63 is arranged, the middle part of the spray pipe 63 rotates around the hinge point 64 to form a circular pipe section 632. When the spray pipe 63 rotates with the rotating plate 62, the spray pipe 63 will not bend significantly, thereby ensuring the fluidity of the water inside the spray pipe 63.

[0117] In addition, after the rotating plate 62 is rotated 90 degrees relative to the fixed plate 61 to open, it can be reset by manually rotating the rotating plate 62 90 degrees in the opposite direction and clamped and fixed by a mechanical switch or a magnetic switch. Due to the existence of the pipe joint 632, the spray pipe 63 is gradually tightened during the resetting process, thereby eliminating the loosening of the spray pipe 63 during use.

[0118] Example 5

[0119] like Figure 23 to Figure 25 As shown, a parking space fire protection device of the present embodiment is different from that of embodiment 4 in that, in the present embodiment, a plurality of sprinkler pipes 63 are directly arranged on the inner side surface of the lower plate body 1, the plurality of sprinkler pipes 63 are arranged at equal intervals along the first direction, and each sprinkler pipe 63 is a corrugated pipe so that the sprinkler pipe 63 can be extended toward the bottom of the vehicle, and the plurality of sprinkler pipes 63 are driven to extend and retract by a telescopic driving device such as a telescopic cylinder and a plurality of water outlet holes 631 are arranged above the ends thereof extending into the bottom of the vehicle on fire.

[0120] When a fire is detected, the telescopic cylinder drives the spray pipe 63 to extend and then extend into the bottom of the burning vehicle. At this time, the water network supplies water to the spray pipe 63 and sprays water towards the bottom of the burning vehicle to cool it down, thereby achieving the purpose of cooling and extinguishing the fire.

[0121] The present application also provides a parking space fire prevention system, which includes the parking space fire prevention device described in any one of embodiments 1-5. The system can be applied to ground parking spaces or underground parking spaces, and at least one parking space fire prevention device can be provided. The overall length, width, and height of the parking space fire prevention device when fully extended can be flexibly designed according to needs.

[0122] The parking line of a parking space is generally rectangular and has four sides. When three sides of a parking space are wall structures, it is only necessary to set the fire prevention device on the fourth side of the parking space (embedded design, convenient for cars to enter the garage), and the parking space fire prevention device can be set as one. When two sides of a parking space are wall structures, it is only necessary to set the fire prevention device on the other two sides of the parking space (at least one side is "embedded design", convenient for cars to enter the garage), and the parking space fire prevention device can be set as two; when one side of a parking space is a wall structure, it is only necessary to set the fire prevention device on the other three sides of the parking space (at least one side is "embedded design", convenient for cars to enter the garage), and the parking space fire prevention device can be set as three; when there are no wall structures on all four sides of the parking space, the fire prevention device can be set on all four sides of the parking space, and the number of fire prevention devices is set to four (at least one side is "embedded design", convenient for cars to enter the garage), and the lengths of the four fire prevention devices can be designed according to the lengths of the parking lines on the four sides of the parking space. When the parking space is an underground parking space, the number of fire protection devices can be set to five. After four fire protection devices are set on the four sides of the parking line, a fire protection device is set on the wall above the parking space, and the fire protection device is horizontally spread to protect the parking space. It should be noted that when the length of the parking line on one side is long, more than two fire protection devices can be spliced ​​in sequence.

[0123] It should be noted that when the parking space is underground, the fire protection devices on the four sides of the parking space can also be correspondingly installed on the wall above the parking space, that is, the "suspension design", by fixing the upper plate 2 on the upper wall to achieve suspension. When the telescopic folding mechanism 3 is in operation, the upper plate 2 is fixed and the lower plate 1 is lowered. At this time, it is necessary to reasonably design the height of each fire protection device when it is fully extended, so that when the lower plate 1 is lowered to the lowest position, it can reach the ground to protect the vehicles in the surrounding parking spaces.

[0124] The fire protection system can also be used for regional fire protection of all parking spaces in an area, that is, it can be arranged for a row of parking spaces or several rows of parking spaces. For example, when it is for several rows of parking spaces in a rectangular area, fire protection devices are installed on the four sides of the area in turn to provide overall protection for the four sides of the area.

[0125] Preferably, the fire protection system is used to automatically pop out the fireproof cloth 4 structure when a fire is sensed, providing semi-enclosed or fully enclosed protection measures for vehicles in danger to prevent the fire from spreading to other parking spaces. The fire protection device composed of multiple ground-pulled fireproof cloths 4 is spliced ​​to complete the semi-enclosed protection of the parking space, such as Fig.16 and Fig.17As shown, it is the preferred design scheme in this embodiment (fireproof devices are arranged on the three sides of the parking space respectively), which presents the overall external effect of the floor-pull fireproof cloth 4 when it is folded and opened. Each floor-pull fireproof cloth 4 is fixed to the parking line on the ground by bolts. The width of each device is 200mm (equivalent to the width of the parking line), and it will not take up additional area; the length is 2500mm, and the standard parking space is generally 2500*5000mm. When used, two floor-pull fireproof cloths 4 are deployed on each side, and one floor-pull fireproof cloth 4 is deployed on the back. The unfolded height of the fireproof cloth 4 is 1500mm, which can effectively isolate and protect common new energy vehicles from thermal runaway. The single body size of the floor-pull fireproof cloth 4 adapts to the current parking space size, with 2 deployed on each side and 1 deployed on the back, for a total of 5.
