Description

Technical Field

[0001] This invention relates to the technical field of fire hydrant boxes for rooftop parking lots, specifically to a fire hydrant box for a rooftop parking lot. Background Technology

[0002] Rooftop parking is parking on the roof of a building. Parking lots are places for vehicles to park; some are simple parking lots with only marked parking spaces and no management or payment, while others are paid parking lots with entrances / exits, parking attendants, and hourly cashiers. Rooftop parking utilizes the unused space on the roof, solving most parking problems. Fire hydrant boxes are boxes used to store fire hydrants for extinguishing fires. They need to be equipped with hoses, nozzles, etc., and can be installed in exposed, concealed, or semi-concealed ways. Fire hydrant boxes can also hold multiple fire extinguishers for extinguishing temporary, localized fires. The outer door panel is fitted with a transparent acrylic panel for easy monitoring of the lifespan of the fire extinguishers and other components inside the hydrant.

[0003] The use of existing fire hydrant boxes in rooftop parking lots presents the following technical problems: Rooftop parking lots are typically found only in large shopping malls and supermarkets, resulting in a large roof area and the capacity to accommodate more vehicles, thus increasing the probability of vehicle fires. Fires of different sizes can be handled by connecting fire hydrants to spray nozzles or fire extinguishers. However, with existing fire hydrant boxes, regardless of the size of the fire, the door must be opened first before accessing a fire hose or fire extinguisher. When using both fire hoses and fire extinguishers, the area in front of the fire hydrant box... First, the fire hydrant box door needs to be opened outwards around the hinge connecting the door and the fire hydrant box. After opening, the area in front of the fire hydrant is limited by the opening of the door, making it difficult for multiple firefighters to quickly retrieve both items from the fire hydrant box at the same time, increasing the time wasted. Furthermore, when using the fire hose, it needs to be completely removed, stretched out, and laid flat. It is important to ensure that one end of the fire hose is connected to the quick-connect coupling, and then the quick-connect coupling is connected to the water outlet on the fire hydrant before proceeding with the proper operation, further increasing the time wasted in firefighting operations. Summary of the Invention

[0004] This invention proposes a fire hydrant box for rooftop parking lots, which allows the door panel to be opened quickly and fully. When the door panel falls, one end of the fire hose automatically engages with the fire hydrant outlet, shortening the time for connecting fire-fighting equipment and further reducing the loss of fire-fighting time.

[0005] The technical solution of the present invention is as follows:

[0006] A fire hydrant box for a rooftop parking lot includes a door panel and a fire hydrant box. The fire hydrant box contains nozzles and fire hoses, and a fire hydrant is connected to the bottom wall of the box. Several fire extinguishers are installed on both sides of the fire hydrant box. The key feature is that a transmission assembly automatically engages one end of the fire hose with the fire hydrant interface between the door panel and the fire hydrant box. A screw-in assembly is connected to the lower side of the transmission assembly, which is driven by the downward movement of the door panel. A pressure block is fixedly connected to the door panel to drive the screw-in assembly. A threaded blind hole is provided on the side of the door panel facing the fire hydrant box, driving a component of the transmission assembly. A sliding assembly connects the door panel and the fire hydrant box, allowing the door panel to move relatively smoothly relative to the fire hydrant box. Pins are slidably connected to the door panel to limit and fix the door panel and the fire hydrant box.

[0007] The transmission assembly includes a transmission column, one side of which has an external threaded surface. The transmission column is threaded into a blind hole. A transmission gear slides and abuts against the other side of the transmission column. A linkage column is slidably connected to the end of the transmission column away from the door panel. A top plate is fixedly connected to the end of the linkage column away from the transmission column. A locking block is rotatably connected to the other end of the top plate. A locking ring is fixedly connected to the locking block. The other end of the fire hose is fixedly connected between the locking ring and the locking block.

[0008] A top column is fixedly connected to the end of the transmission column away from the door panel. An ejector hole is provided on the top plate. The top column abuts against the side of the top plate. A pressure spring abuts inside the transmission column. The two ends of the pressure spring abut against the inner wall of the transmission column and the linkage column, respectively.

[0009] The screw-in assembly includes two sets of limiting plates. Each set of limiting plates consists of two limiting plates, both of which are fixedly connected to the bottom wall of the fire extinguishing box. A reset post is fixedly connected between each set of limiting plates. A sliding block is slidably connected to each set of limiting plates. A sliding post is fixedly connected to each sliding block. A transmission rack is slidably connected to the two sliding posts. A flipping block is fixedly connected to one side of the sliding block. A transmission plate is hinged to the flipping block. The end of the transmission plate away from the flipping block abuts against the outer wall of the fire extinguishing box and is fixedly connected to a receiving block.

[0010] Furthermore, each of the sliding columns is fitted with a sliding spring, the two ends of which abut against the transmission rack and the sliding block, respectively. A reset spring is fitted on the reset column away from the receiving block, the two ends of which abut against the limiting plate and the sliding block, respectively.

[0011] Furthermore, the sliding assembly includes two slide rails, both of which are fixedly connected to the side of the fire extinguisher box facing the door panel. Each slide rail is slidably connected to a slider, and each slider is fixedly connected to the door panel. A limit block is fixedly connected to one end of the lower side of each slide rail.

[0012] Furthermore, two placement compartments are fixedly connected to the outer walls on both sides of the fire extinguishing box, and each fire extinguisher is placed in its respective placement compartment. The fire extinguishing box is provided with snap-fit ​​holes, and the pins abut against the inner walls of the snap-fit ​​holes.

[0013] Furthermore, a limiting groove is provided on the fire extinguishing box, and the end of the transmission plate near the limiting groove abuts against the inner wall of the limiting groove. A handle is fixedly connected to the side of the door panel away from the fire extinguishing box.

[0014] The working principle and beneficial effects of this invention are as follows:

[0015] In this invention, the transmission component works in conjunction with the screw-in component to automatically engage the fire hose with the fire hydrant outlet as the door panel moves downward. This reduces the time spent operating fire-fighting equipment in case of fire. After use, the fire hose is wound up and placed on the reel. After repairing the outlet switch, the door panel is reset, and the connection between the fire hose and the fire hydrant automatically separates, reducing the need for manual operation of the fire-fighting equipment and facilitating maintenance for both personnel and users. Fire extinguishers are placed on both sides of the fire extinguisher box, separating their access from the fire hose and making them easier to retrieve, further reducing the time wasted when using fire-fighting equipment.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1-7 As shown, this embodiment proposes a fire hydrant box for a rooftop parking lot. A transmission assembly 2, which automatically engages one end of the fire hose 152 with the corresponding outlet of the fire hydrant 154, is connected between the door panel 13 and the fire hydrant box 15. A screw-in assembly, which drives the transmission assembly 2 by the downward movement of the door panel 13, is connected to the lower side of the transmission assembly 2. The transmission assembly 2, in conjunction with the screw-in assembly, automatically engages the fire hose 152 with the outlet of the fire hydrant 154 as the door panel 13 moves downward. This reduces the time cost associated with operating fire-fighting equipment in the event of a fire. After use, the fire hose 152 is wound up and placed on a reel. After repairing the water outlet switch, the door panel 13 is reset. The connection between the fire hose 152 and the fire hydrant 154 is automatically separated, reducing the need for operation of fire-fighting equipment and facilitating maintenance by maintenance personnel and users. The pressure block 131 that drives the screw-in assembly is fixedly connected to the door panel 13. The threaded blind hole 133 that is linked with the transmission assembly 2 is opened on the side of the door panel 13 facing the fire box 15. The sliding assembly that allows the door panel 13 to move relatively smoothly with the fire box 15 is connected between the door panel 13 and the fire box 15. The door panel 13 slides against the pin 11 that limits and fixes the door panel 13 and the fire box 15. The pin 11 can be quickly pulled out, allowing the door panel 13 to be opened quickly, further reducing the time wasted in retrieving fire-fighting equipment.

[0027] like Figures 4-7As shown, one side of the transmission column 23 has an external thread surface. The transmission column 23 is threadedly connected to the threaded blind hole 133. The other side of the transmission column 23 slides against the transmission gear 24. The end of the transmission column 23 away from the door panel 13 is slidably connected to the linkage column 28. The top plate 25 is fixedly connected to the end of the linkage column 28 away from the transmission column 23. The other end of the top plate 25 is rotatably connected to the latch block 21. The latch block 21 is fixedly connected to the locking ring 26. The other end of the fire hose 152 is fixedly connected between the locking ring 26 and the latch block 21. The rotation of the transmission gear 24 can drive the transmission column 23 to rotate, thereby causing the transmission column 23 to move towards the latch block 21 through the threaded connection with the threaded blind hole 133. At the same time, because the center of gravity of the latch block 21 is downward, the latch block 21 will only move with the transmission column 23 and will not rotate.

[0028] like Figures 4-7 As shown, the top column 22 is fixedly connected to the end of the transmission column 23 away from the door panel 13. The ejection hole 251 is opened on the top plate 25. The top column 22 abuts against the side of the top plate 25 and the ejection hole 251. The transmission column 23 abuts against the pressure spring 27. The two ends of the pressure spring 27 abut against the inner wall of the transmission column 23 and the linkage column 28, respectively. When the other end of the fire hose 152 has abutted against the water outlet of the fire hydrant 154, the transmission column 23 will continue to move under the action of the pressure spring 27, so that the top column 22 is ejected from the ejection hole 251, and then the top column 22 lifts the side of the latch block 21, so that the latch block 21 can rotate with the transmission column 23, and then the fire hose 152 is engaged with the water outlet of the fire hydrant 154.

[0029] like Figure 3 and Figure 4 As shown, a set of limiting plates 34 consists of two limiting plates 34, both of which are fixedly connected to the bottom wall of the fire extinguishing box 15. Each reset post 32 is fixedly connected between each set of limiting plates 34. Each set of limiting plates 34 is slidably connected to each sliding block 36, limiting the movement of the sliding block 36 and making the sliding of the sliding block 36 more stable. Each sliding block 36 is fixedly connected to each sliding post 35. The two sliding posts 35 slide against the transmission rack 33, allowing the transmission rack 33 to slide up and down on the two sliding posts 35. A flipping block 39 is fixedly connected to one side of the sliding block 36. The flipping block 39 is hinged to the transmission plate 37. The end of the transmission plate 37 away from the flipping block 39 abuts against the outer wall of the fire extinguishing box 15 and is fixedly connected to the receiving block 38.

[0030] like Figure 2 and Figure 3As shown, the sliding spring 351 is sleeved on each sliding post 35. The two ends of the sliding spring 351 abut against the transmission rack 33 and the sliding block 36 respectively, so that after the transmission gear 24 moves down with the door panel 13, the transmission rack 33 can also move down and mesh with the transmission gear 24. The movement of the transmission rack 33 drives the transmission gear 24 to rotate. The return spring 31 is sleeved on the return post 32 on the side away from the receiving block 38. The two ends of the return spring 31 abut against the limit plate 34 and the sliding block 36 respectively, so that after the door panel 13 is reset, the transmission rack 33 is also reset under the action of the return spring 31, which is convenient for the next operation.

[0031] like Figures 1-4 As shown, both slide rails 14 are fixedly connected to the side of the fire extinguisher box 15 facing the door panel 13. Each slide rail 14 is slidably connected to each slider 132. Each slider 132 is fixedly connected to the door panel 13. One end of the lower side of each slide rail 14 slides and abuts against each limiting block 16, making the falling of the door panel 13 more stable and limiting the sliding of the door panel 13.

[0032] like Figure 1 and Figure 2 As shown, two storage compartments 155 are fixedly connected to the outer walls of the fire extinguisher box 15 on both sides. Each fire extinguisher 153 is placed in its respective storage compartment 155. The locking hole 156 is opened on the fire extinguisher box 15. The pin 11 abuts against the inner wall of the locking hole 156. When the pin 11 penetrates the door panel 13 and abuts against the inner wall of the locking hole 156, it means that the door panel 13 is flush with the fire extinguisher box 15. The fire extinguishers 153 are placed on both sides of the fire extinguisher box 15, so that the access position of the fire extinguisher 153 is separated from the fire hose 152, which can better retrieve these items and further reduce the time loss when retrieving fire equipment.

[0033] like Figures 1-3 As shown, the limiting groove 157 is formed on the fire box 15. The end of the transmission plate 37 near the limiting groove 157 abuts against the inner wall of the limiting groove 157. The limiting groove 157 allows the receiving block 38 to move up and down only along the Z-axis, thus limiting the position of the receiving block 38. The side of the door panel 13 away from the fire box 15 is fixedly connected to the handle 12. The handle 12 is used to better apply force when resetting the door panel 13 after use.

[0034] The working principle of this embodiment is as follows:

[0035] When taking fire extinguisher 153, it can be taken from both sides of fire extinguisher box 15 without obstructing the operation of fire hydrant;

[0036] When the fire hydrant hose is needed, pull out the pin 11, causing the door panel 13 to move down. After moving down a certain distance, the pressure block 131 contacts the receiving block 38, causing the receiving block 38 to move down. This causes the sliding block 36 to move to one side, which in turn moves the transmission rack 33. At this time, the transmission gear 24 has also moved down a certain distance and is engaged with the transmission rack 33. Therefore, the movement of the transmission rack 33 will cause the transmission gear 24 to rotate, thereby causing the transmission column 23 to unscrew from the threaded blind hole 133. Because the center of gravity of the locking block 21 is downward, the locking block 21 will only move with the transmission column 23 and will not rotate. When one end of the fire hose 152 abuts against the outlet interface of the fire hydrant 154, the locking block 21 stops moving, and the transmission column 23 continues to move. The top post 22 will be pushed out from the top hole 251, and the top post 22 will push against the side of the latch block 21, so that the latch block 21 will rotate with the transmission post 23, and then the fire hose 152 will be engaged with the water outlet of the fire hydrant 154. Since the rotation of the transmission gear 24 is driven by the downward movement of the door panel 13, the transmission rack 33 is also capable of moving up and down on the two sliding posts 35. Under the action of the sliding spring 351, the meshing of the transmission rack 33 and the transmission gear 24 will be more stable. Take the other end of the fire hose 152 off the reel, lay it flat on the open ground, and engage the nozzle 151 with this end. Break the water outlet switch, and then ensure that the fire hose 152 is placed without any corners. Unscrew the turntable on the fire hydrant and wait for the water to come out. The water will come out through the fire hose 152 to extinguish the fire.

[0037] After finishing the work, squeeze out the remaining water from the fire hose 152, coil it into a circle and place it on the reel. Repair the water outlet switch, reset the door panel 13, and place the nail pin 11 on it. The reset of the door panel 13 will cause the transmission gear 24 to reverse, thereby resetting all parts and waiting for the next work.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
