Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a stackable metal shelving unit. Background Technology

[0002] A tiered metal shelving unit is a type of furniture designed to provide storage space. Its main feature is that it has multiple shelves to divide the storage space. These shelves are usually made of metal materials, such as steel or aluminum, and are sturdy and durable, capable of bearing a certain weight. They are widely used in homes, offices, warehouses, and other places to store various items such as books, documents, decorations, and kitchenware.

[0003] In existing technologies, stacked metal shelving systems pose significant safety hazards when storing goods, especially flammable items. Because these shelving systems are typically designed with an open structure, flames and smoke can rapidly spread through each layer in the event of a fire, leading to a rapid spread of the fire. Furthermore, the multi-layered design makes early detection of flames difficult, particularly in large warehouse environments. Existing fire monitoring systems may fail to detect initial fires in time, delaying optimal firefighting efforts. Worse still, the effectiveness of automatic sprinkler systems may be limited during a fire, as metal partitions can obstruct the even distribution of water, preventing water from adequately and accurately covering all fire sources. This not only exacerbates the spread of the fire but can also lead to greater economic losses and safety hazards, including but not limited to structural damage to buildings, complete destruction of stored goods, and potential threats to personnel safety.

[0004] Therefore, a high-safety-performance stackable metal shelving unit is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stacked metal shelf.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stackable metal shelf includes: a base, a top plate, several vertically arranged support rods, and several partitions. The two ends of each support rod are fixed to the upper surface of the base and the lower surface of the top plate, respectively. The partitions are located between all the support rods and are fixedly connected to them. A monitoring module for monitoring fire is mounted on one of the partitions. A fireproof curtain with a U-shaped cross-section is fixed to the lower surface of the top plate, and all the support rods and partitions are located inside the fireproof curtain. A control assembly for controlling the descent of the fireproof curtain is mounted on the top plate.

[0008] As a preferred embodiment of this utility model, the control component includes: a counterweight block with a U-shaped cross-section, which is fixed to the bottom of the fireproof curtain; several pull ropes, one end of which is fixedly connected to the counterweight block, the top plate being hollow, and the other end of which is fixed to the inner top surface of the top plate; an electric telescopic rod fixedly connected to the inner side of the top plate; and a blade fixed to the telescopic end of the electric telescopic rod, with all the pull ropes corresponding to the blade.

[0009] As a preferred embodiment of this utility model, the top plate is provided with a protective assembly, which includes: a storage cylinder containing a water source, fixed to the inner side of the top plate; a push rod with a transverse T-shaped cross-section, one end of which is slidably and sealed to the inner side of the storage cylinder, and the other end of which is fixed to the telescopic end of an electric telescopic rod; a connecting pipe connected to the storage cylinder; several cavities respectively disposed in the top plate and the partition, the cavities being connected to the connecting pipe; and several air holes disposed on the inner top surface of the top plate and the bottom of the partition, the air holes being connected to the cavities.

[0010] As a preferred embodiment of this utility model, the fireproof curtain has several flexible hoses fixed on its inner side, and all of the flexible hoses are connected to the connecting pipe. Several air holes are provided on the flexible hoses.

[0011] As a preferred embodiment of this utility model, the inner side of the counterweight is provided with a plurality of pulleys, the support rod is provided with a groove facing the side wall of the counterweight, and the pulleys are located inside the groove.

[0012] As a preferred embodiment of this invention, a buffer pad is fixed to the bottom of the counterweight.

[0013] This utility model has the following beneficial effects:

[0014] 1. Enhance fire monitoring and response speed: By installing smoke detectors or temperature sensors in the middle of the shelving unit, the occurrence of fire can be detected more promptly and accurately. Especially for multi-layer shelving units, this design can effectively make up for the monitoring blind spots that may exist in traditional fire protection systems and achieve the goal of rapid fire isolation.

[0015] 2. Automatic fire curtain deployment: When a fire occurs, the electric telescopic rod is activated, the pull rope is cut, and the counterweight causes the fire curtain to descend rapidly and cover the entire shelf. This mechanism effectively prevents the fire from spreading to other shelves and reduces the risk of fire spread.

[0016] 3. Optimize water flow distribution and fire extinguishing efficiency: By setting up cavities and hoses, air vents one and two can spray water onto the top and sides of the goods, ensuring that water can evenly cover the fire source, improving the effectiveness and range of fire extinguishing, and solving the problem of insufficient fire extinguishing caused by the obstruction of partitions in traditional sprinkler systems;

[0017] 4. Enhance safety and reduce economic losses: The use of automated components such as electric telescopic rods, blades, and push rods enables rapid deployment of fire curtains and immediate release of water, reducing the need for manual intervention, improving the speed and reliability of response to emergencies, and thus enhancing the safety performance of the shelving unit, minimizing losses caused by fire.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-3A stackable metal shelving unit includes: a base 1, a top plate 2, several vertically arranged support rods 3, and several partitions 4. The partitions 4 are used to place goods. The two ends of the support rods 3 are fixed to the upper surface of the base 1 and the lower surface of the top plate 2, respectively. The partitions 4 are located between all the support rods 3, and the partitions 4 and the support rods 3 are fixedly connected by welding. A monitoring module 5 is used to monitor fire. The monitoring module 5 is set on one of the partitions 4. Further, the monitoring module 5 is a smoke detector or a temperature sensor, and the monitoring module 5 is located in the middle of the shelving unit, which can monitor the fire situation inside the shelving unit in a timely manner. A fireproof curtain 6 with a U-shaped cross-section is fixed to the lower surface of the top plate 2. All the support rods 3 and the partitions 4 are located inside the fireproof curtain 6. The fireproof curtain 6 is provided with horizontal pleats, which can be folded layer by layer along the pleats when stored. In the event of a fire, the fireproof curtain 6 can wrap the entire shelving unit to prevent the fire from spreading to other shelving units.

[0025] It also includes a control component for controlling the descent of the fire curtain 6. The control component is mounted on the top plate 2 and includes a counterweight 7. The counterweight 7 has a U-shaped cross-section and is fixed to the bottom of the fire curtain 6. The downward movement of the counterweight 7 can cause the fire curtain 6 to unfold rapidly, thereby achieving the purpose of wrapping the shelf. Several pulleys 18 are provided on the inner side of the counterweight 7. The support rod 3 has a groove 19 on its side wall facing the counterweight 7. The pulleys 18 are located inside the groove 19. The pulleys 18 can reduce the friction between the counterweight 7 and the support rod 3 when it moves downward. In addition, the pulleys 18 and the groove 19 can guide the movement of the counterweight 7. This allows the fireproof curtain 6 to be aligned with the edge of the upper surface of the base 1. The bottom of the counterweight 7 is fixed with a cushioning pad to protect the shelf. Several pull ropes 8 are attached, one end of which is fixed to the counterweight 7. The interior of the top plate 2 is hollow, and the other end of the pull ropes 8 is fixed to the inner top surface of the top plate 2. An electric telescopic rod 9 is fixed to the inner side of the top plate 2. Furthermore, the electric telescopic rod 9 is connected to the monitoring module 5. When the monitoring module 5 detects a fire, it will activate the electric telescopic rod 9. A blade 10 is used to cut the pull ropes 8. The blade 10 is fixed to the telescopic end of the electric telescopic rod 9, and all the pull ropes 8 correspond to the blade 10.

[0026] When the monitoring module 5 detects a fire inside the shelf, the electric telescopic rod 9 is activated. The telescopic end of the electric telescopic rod 9 extends and drives the blade 10 to move. The blade 10 can cut all the pull ropes 8. At this time, the counterweight 7 is no longer under the tension of the pull ropes 8 and will fall rapidly under its own weight. The downward movement of the counterweight 7 will pull the bottom of the fireproof curtain 6, causing the bottom of the fireproof curtain 6 to move onto the base 1, thereby wrapping the partition 4 and the goods together, effectively isolating the outside air, and thus quickly preventing the spread of fire, reducing safety hazards and economic losses.

[0027] Example 2

[0028] Reference Figure 2 and Figure 3 The top plate 2 is equipped with a protective assembly, which includes: a storage cylinder 11 containing a water source, fixed to the inside of the top plate 2; a push rod 12 with a transverse T-shaped cross-section, one end of which is slidably connected to the inside of the storage cylinder 11, and the other end of which is fixed to the telescopic end of the electric telescopic rod 9; a connecting pipe 13 connected to the storage cylinder 11; several cavities 14 respectively set in the top plate 2 and the partition 4, and the cavities 14 are connected to the connecting pipe 13; and several air holes 15 set on the top surface of the top plate 2 and the bottom of the partition 4, and the air holes 15 are connected to the cavities 14.

[0029] Furthermore, several flexible hoses 16 are fixed to the inner side of the fireproof curtain 6, and all the flexible hoses 16 are connected to the connecting pipe 13. Several air holes 17 are opened on the flexible hoses 16.

[0030] In the event of a fire, the telescopic end of the electric telescopic rod 9 moves, causing the blade 10 to cut the pull rope 8, which in turn causes the counterweight 7 and the fire curtain 6 to descend rapidly. At the same time, the movement of its telescopic end also pushes the push rod 12 to move. The push rod 12 can squeeze the water in the storage cylinder 11, allowing the water to enter the cavity 14 and the hose 16 through the connecting pipe 13. The water is then sprayed out through the first vent 15 and the second vent 17. The water in the first vent 15 can extinguish the fire on the top of the goods, and the water in the second vent 17 can extinguish the fire on the sides of the goods after the fire curtain 6 is deployed. This increases the fire extinguishing area and improves safety performance.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
