Description

Technical Field

[0001] The present invention belongs to the technical field of fire protection devices, and in particular relates to a multiple fire protection device for an automatic shelf and a protection method thereof. Background Art

[0002] Automatic shelves are a storage solution that integrates automation technology. They use motor drive and roller track systems to achieve the function of moving on preset tracks. This innovative design significantly improves the space utilization of warehouses and greatly improves the efficiency of goods storage and retrieval. Automatic shelves are usually used in high-density storage environments to maximize the use of limited space resources by closely arranging items on the shelves.

[0003] However, since the items on the shelves are stacked very closely, once a fire occurs, the fire can spread quickly. In order to ensure rapid response and effective fire extinguishing when a fire occurs, while protecting the safety of goods and warehouse facilities, the automatic shelf system is usually equipped with multiple fire protection devices. At present, the most common fire extinguishing method among fire protection measures is the use of a water sprinkler system;

[0004] The water sprinkler system is implemented by installing sprinklers above the shelves. Once a fire is detected, the sprinklers will automatically start and spray a large amount of water to extinguish the flames. However, the water after spraying will flow downward, which will not only pollute the environment, but may also cause damage to goods in other non-fire areas. Water penetration and immersion may cause damage to goods and even affect the normal operation of other equipment in the warehouse. Summary of the invention

[0005] The object of the present invention is to provide a multiple fire protection device for an automatic shelf and a protection method thereof to solve the problems raised in the above-mentioned background technology.

[0017] A protection method for multiple fire protection devices of an automatic shelf, comprising the following steps:

[0018] S1: When the automatic shelf is in use, the temperature and smoke alarm is used to monitor the storage chamber between each two partitions in real time. When the temperature and smoke alarm detects abnormal temperature or excessive smoke concentration, the water pump is started and the corresponding solenoid valve and motor are opened. At the same time, an alarm is issued and the alarm information is uploaded to the WMS system for warning;

[0019] S2: When the water pump is started, water is drawn from the water tank through the water pipe and enters the second connecting pipe through the first connecting pipe, and finally discharged from the nozzle to spray the goods in the shelf for fire protection. The sprayed water falls on the top of the partition and enters the partition through the recovery hole, and finally is discharged back into the water tank from the recovery pipe to recycle the used water.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention cooperates with each other through the spray component and the recovery component. When the automatic shelf is in use, real-time monitoring is performed through the temperature and smoke alarm. When the temperature and smoke alarm detects abnormal temperature or too high smoke concentration, it will sound an alarm and upload the alarm information to the WMS system. At the same time, the water pump is started and the solenoid valve is opened. The water source in the water tank is drawn through the water pipe and enters the second connecting pipe through the first connecting pipe, and is finally discharged from the nozzle to spray the goods in the shelf for fire protection. The sprayed water falls on the top of the partition and enters the partition from the recovery hole, and is finally discharged into the water tank from the recovery pipe. The used water is recycled to minimize the negative impact of water spraying on the environment and goods, so as to achieve a safer and more environmentally friendly warehousing solution.

[0023] 2. The present invention fully filters the recovered water by setting the second filter and the third filter to prevent key equipment such as nozzles and pipelines from being worn or blocked due to impurities in the water during long-term use. Through recycling and filtering, the erosion of impurities on these equipment can be reduced, thereby extending the life of the device.

[0024] 3. The present invention sets an isolation component. When the shelf is sprayed with fire protection, the threaded rod is driven to rotate by starting the motor. The rotation of the threaded rod drives the movement of the movable plate. The movement of the movable plate pulls the fireproof cloth to unfold from one side of the partition, and closes the space between every two partitions where the fire has started. When a fire occurs, the fire source is isolated to prevent the fire from spreading to other areas. It not only has a fire protection function, but also can block the spread of smoke and toxic gases to a certain extent, thereby improving the fire protection effect of the device.

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, in an embodiment of the present invention, a multiple fire protection device for an automatic shelf includes a shelf body 1, a partition 2 is fixedly installed inside the shelf body 1, the partitions 2 are evenly distributed, a spray assembly and a recovery assembly are arranged inside the partition 2, and a temperature and smoke alarm 11 is evenly installed inside the shelf body 1;

[0035] The spray assembly includes a second connecting pipe 10 arranged inside the partition 2, a nozzle 9 is evenly installed at the bottom end of the second connecting pipe 10, one end of the second connecting pipe 10 is fixedly connected to the first connecting pipe 7, an outer wall of the first connecting pipe 7 is installed with a solenoid valve 8, the first connecting pipe 7 is embedded in the interior of the partition 2, one end of the first connecting pipe 7 away from the second connecting pipe 10 is fixedly connected to the water pipe 6, the outer wall of the water pipe 6 is installed with a water pump 5, the bottom end of the water pipe 6 is embedded in the interior of the water tank 3, and the water tank 3 is installed on one side of the shelf body 1;

[0036] The recovery component includes recovery holes 12 opened inside the partition 2, and the recovery holes 12 are evenly distributed. A recovery pipe 13 is fixedly installed inside the partition 2, and one end of the recovery pipe 13 away from the partition 2 is embedded in the water tank 3. An isolation component is provided on one side of the partition 2.

[0037] By coordinating the spraying component and the recycling component, when the automatic shelf is in use, real-time monitoring is performed through the temperature and smoke alarm 11. When the temperature and smoke alarm 11 detects abnormal temperature or too high smoke concentration, it will sound an alarm and upload the alarm information to the WMS system. At the same time, the water pump 5 is started and the solenoid valve 8 is opened. The water source in the water tank 3 is drawn through the water pipe 6 and enters the second connecting pipe 10 through the first connecting pipe 7, and is finally discharged from the nozzle 9 to spray the goods in the shelf for fire protection. The sprayed water falls on the top of the partition 2 and enters the partition 2 from the recovery hole 12, and is finally discharged from the recovery pipe 13 back into the water tank 3, and the used water is recycled to minimize the negative impact of water spraying on the environment and goods, so as to achieve a safer and more environmentally friendly warehousing solution.

[0038] like Figure 3 and Figure 5 As shown, a one-way valve 14 is installed on the outer wall of the recovery pipe 13 , and the one-way valve 14 is installed inside the partition 2 .

[0039] The one-way valve 14 prevents the water in the water tank 3 from entering the partition 2 from the recovery pipe 13, so as to ensure the stability of the recovery of the spray water.

[0040] like Figures 1 to 5 As shown, a first filter screen 15 is installed at the top of the recovery hole 12 .

[0041] The spray water is filtered through the first filter screen 15 and then recycled to prevent the spray water from carrying away impurities on the surface of the goods or in the air when in use. Excessive or large impurities entering the recovery hole 12 will not only block the recovery hole 12, but also affect the cleanliness of the recycled water.

[0042] like Figures 1 to 7 As shown, a second filter screen 16 is disposed inside the water tank 3 , and the second filter screen 16 is disposed on one side of the one-way valve 14 .

[0043] The water recovered in the water tank 3 is filtered through the second filter screen 16 to remove impurities such as dust and particulate matter that may be mixed into the air during the spraying process, thereby improving the purity of the recovered water.

[0044] like Figure 3 and Figure 7 As shown, a third filter screen 17 is disposed inside the water tank 3 , and the third filter screen 17 is disposed at the bottom end of the first connecting pipe 7 .

[0045] like Figure 7As shown, the second filter screen 16 and the third filter screen 17 form an L shape.

[0046] The recycled water is fully filtered through the second filter 16 and the third filter 17 to prevent the nozzle 9, pipelines and other key equipment from being worn or blocked due to impurities in the water during long-term use. By recycling and filtering, the erosion of impurities on these equipment can be reduced, thereby extending the life of the device;

[0047] The water inlet end of the first connecting pipe 7 is located between the L-shapes, and when water is drawn to spray and extinguish a fire, clean water is drawn.

[0048] like Figure 1 and Figure 2 As shown, a cover plate 4 is mounted on the top of the water tank 3 via bolts 24 .

[0049] The cover plate 4 is disassembled and assembled by bolts 24 for maintenance inside the water tank 3 .

[0050] like Figure 1 and Figure 2 As shown, the cover plate 4 is provided with exhaust holes 23 inside, and the exhaust holes 23 are evenly distributed.

[0051] Due to the flow of water in and out of the water tank 3 and the temperature changes during use, a negative pressure state may be generated inside. Exhausting air through the exhaust hole 23 can effectively reduce this negative pressure state, avoid damage to the water tank 3 due to pressure imbalance, ensure that the water tank 3 operates in a normal working state, and thus improve the stability of the device during operation.

[0052] like Figure 1 , Figure 2 and Figure 6 As shown, the isolation assembly includes a movable plate 20 slidably mounted on one side of the partition 2, the internal thread of the movable plate 20 is connected to a threaded rod 21, one end of the threaded rod 21 is installed with a motor 22, and one side of the movable plate 20 is fixedly installed with a fireproof cloth 18, the fireproof cloth 18 is installed on the outer wall of the mounting roller 19, and the mounting roller 19 is embedded in the interior of the shelf body 1.

[0053] The fireproof cloth 18 is made of a material with good high temperature resistance and fireproof performance;

[0054] Through the setting of the isolation component, when the shelf is sprayed with fire protection, the threaded rod 21 is driven to rotate by starting the motor 22. The rotation of the threaded rod 21 drives the movement of the movable plate 20. The movement of the movable plate 20 pulls the fireproof cloth 18 to unfold from one side of the partition 2, and closes the space between every two partitions 2 that are on fire. When a fire occurs, the fire source is isolated to prevent the fire from spreading to other areas. It not only has a fire prevention function, but also can block the spread of smoke and toxic gases to a certain extent, thereby improving the fire protection effect of the device.

[0055] A protection method for multiple fire protection devices of an automatic shelf, comprising the following steps:

[0056] S1: When the automatic shelf is in use, the storage chamber between every two partitions 2 is monitored in real time through the temperature and smoke alarm 11. When the temperature and smoke alarm 11 detects abnormal temperature or excessive smoke concentration, the water pump 5 is started and the corresponding solenoid valve 8 and motor 22 are opened, and an alarm is issued at the same time and the alarm information is uploaded to the WMS system for warning;

[0057] S2: When the water pump 5 is started, the water in the water tank 3 is drawn through the water pipe 6 and enters the second connecting pipe 10 through the first connecting pipe 7, and finally discharged from the nozzle 9 to spray the goods in the shelf for fire protection. The sprayed water falls on the top of the partition 2 and enters the partition 2 through the recovery hole 12, and finally is discharged back into the water tank 3 from the recovery pipe 13 to recycle the used water. The water recovered in the water tank 3 is filtered by the second filter 16 and the third filter 17 and reused;

[0058] S3: When the motor 22 is started, it drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 drives the movement of the movable plate 20. The movement of the movable plate 20 pulls the fireproof cloth 18 to unfold from one side of the partition 2, and closes the space between every two partitions 2 that are on fire, providing precise fire protection.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
