[0020] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] As Figures 1 to 3 shown, a fireproof structure of a stacker of the present utility model includes a load-carrying platform body 1, a fire extinguishing system 2, and a rolling shutter mechanism 3. The fire extinguishing system 2 is installed outside the load-carrying platform body 1, and the rolling shutter mechanism 3 is installed at the loading and unloading positions on both sides of the load-carrying platform body 1. The rolling shutter mechanism 3 includes a driving assembly 4, a fireproof cloth 5, and a counterweight assembly 6. The top end of the fireproof cloth 5 is connected to the driving assembly 4, and the driving assembly 4 drives the fireproof cloth 5 to rise or fall. The bottom of the fireproof cloth 5 is connected to the counterweight assembly 6. During fire extinguishing, the fireproof cloth 5 seals both sides of the load-carrying platform body 1 and forms a fire extinguishing area with the fire extinguishing system 2.

[0022] The rolling shutter mechanism 3 is mainly used to immediately close the fireproof cloth 5 inside the load-carrying platform when a fire occurs, forming a closed space to facilitate the operation of the fire extinguishing system 2. The counterweight assembly 6 is used to increase the downward pulling force and guiding of the fireproof cloth 5.

[0023] The load-carrying platform body 1 is mainly used to fix other mechanisms and is generally welded by square pipes and rectangular pipes. A fork mechanism 11 is installed inside the load-carrying platform body 1. The main function of the fork mechanism 11 is to pick up and place the battery cell assembly 12. The battery cell assembly 12 is placed on the fork mechanism 11. The battery cell assembly 12 is mainly composed of the main parts of the battery module in the new energy industry and can be generally divided into cylindrical, square, and soft-pack battery cells according to the shape. During the production process, when the battery cell assembly 12 malfunctions, it is prone to spontaneous combustion.

[0024] As Figure 2 shown, the driving assembly 4 includes a reel motor 41, a reel 42, a reel support plate 43, and a reel bearing seat 44. The reel bearing seat 44 is connected to the reel support plate 43. Both ends of the reel 42 are respectively connected to the reel bearing seat 44. The reel motor 41 is connected to the reel 42 through the reel bearing seat 44. The fireproof cloth 5 is wound around the reel 42, and the reel motor 41 drives the reel 42 to rotate. The reel motor 41 is preferably a reduction motor.

[0025] The rolling shutter door mechanism 3 further includes a top protective cover 31. The top protective cover 31 is connected to the top of the drum support plate 43 and extends downward to cover the drum 42. The top protective cover 31 protects the top of the drum 42 and the fireproof cloth 5. When the fireproof cloth 5 is retracted on the drum 42, the top protective cover 31 can also cover the position of the fireproof cloth 5, playing a role in protection and aesthetics.

[0026] The rolling shutter door mechanism 3 further includes side protective covers 32. The side protective covers 32 are installed on both sides of the fireproof cloth 5. Both ends of the counterweight assembly 6 are movably connected within the side protective covers 32. When the fireproof cloth 5 descends, the side protective covers 32 wrap around the sides of the fireproof cloth 5. The side protective covers 32 enclose the sides of the fireproof cloth 5 and seal the side areas of the fireproof cloth 5.

[0027] The rolling shutter door mechanism 3 further includes an upper limit detection optoelectronic sensor 33 and a lower limit detection optoelectronic sensor 34. The upper limit detection optoelectronic sensor 33 and the lower limit detection optoelectronic sensor 34 are respectively connected to the upper and lower ends of the side protective cover 32. The upper limit detection optoelectronic sensor 33 and the lower limit detection optoelectronic sensor 34 are used to detect the position of the counterweight assembly 6 relative to the side protective cover 32, thereby limiting the highest and lowest positions when the fireproof cloth 5 is retracted or lowered.

[0028] The rolling shutter door mechanism 3 consists of Figure 2 The key parts shown form a module. The entire module is installed on the load platform of the stacker crane, but is not limited to the stacker crane and can also be installed in places where automatic doors are required. The side protective cover 32, the drum support plate 43, the drum bearing seat 44, and the top protective cover 31 are bolted together to form a rolling shutter door frame. The drum bearing seat 44 is fixed to the entire frame structure. The counterweight mechanism is fixed to the fireproof cloth 5. The fireproof cloth 5 is fixed to the drum 42. The drum motor 41 is fixed to the drum 42 through the drum bearing seat 44. The drum motor 41 is the power drive for the entire mechanism. When the drum motor 41 receives a drive command, it will drive the drum 42 to rotate together. At this time, the fireproof cloth 5 fixed to the drum 42 will also rotate together. Since the fireproof cloth 5 is a flexible and heat-resistant fireproof material, it can rotate with the drum 42 and be wound together. In order to avoid jamming during the lifting process and ensure smooth winding, a counterweight assembly 6 is added to the fireproof cloth 5 to increase the downward pulling force and guiding of the fireproof cloth 5. When rising or falling, the upper limit detection optoelectronic sensor 33 and the lower limit detection optoelectronic sensor 34 detect the position of the counterweight assembly 6 and then stop, completing the opening or closing action.

[0029] As Figure 4As shown, the counterweight assembly 6 includes a counterweight fixing plate 61, a counterweight pressing plate 62, and a guide wheel 63. The counterweight fixing plate 61 is fixed to the bottom of the fireproof cloth 5 through the counterweight pressing plate 62. The guide wheels 63 are connected to both sides of the counterweight fixing plate 61, and the guide wheels 63 are slidably connected inside the side protective cover 32. The guide wheels 63 are divided into side guide wheels 64 provided on the sides of the counterweight fixing plate 61 and front and rear guide wheels 65 provided at the bottom of the counterweight fixing plate 61.

[0030] The counterweight assembly 6 consists of Figure 4 the key parts shown. Since the fireproof cloth 5 is relatively light in weight, it is prone to deformation and wrinkles during the process of descending or ascending. Therefore, it is necessary to perform edge pressing and guiding treatment on the fireproof cloth 5. The counterweight pressing plate 62 and the counterweight fixing plate 61 are attached to the fireproof cloth 5 (the body of the fireproof cloth 5 needs to be folded into an L shape) through screws. The side guide wheels 64 and the front and rear guide wheels 65 are fixed to the counterweight fixing plate 61 through brackets (two groups on each side). In this way, during the lifting and lowering process of the entire counterweight assembly 6, it can be guided and run through rolling friction, making the rolling door open or close more smoothly.

[0031] The fire extinguishing system 2 includes a fireproof armor 21 and a fire extinguisher 22. The fireproof armor 21 covers the outside of the loading platform body 1. The fireproof armor 21 and the rolling door mechanism 3 form a fire extinguishing area. The fire extinguisher 22 is connected to the fireproof armor 21, and the fire extinguishing spray port of the fire extinguisher 22 is docked to the fire extinguishing area.

[0032] The fire extinguishing system 2 is used for cooling, heat insulation, and air isolation of the battery cell assembly 12 to protect the internal parts and sensors of the loading platform. The main core component of the fire extinguishing system 2 is the fire extinguisher 22, and the fire extinguisher 22 is opened or closed through an electromagnetic valve. The fireproof armor 21 is mainly used to form a sealed environment and prevent the spread of fire, and is composed of carbon steel plates installed outside the loading platform.

[0033] The fire extinguishing system 2 further includes a smoke sensor 23, and the smoke sensor 23 is connected to the fireproof armor 21. The smoke sensor 23 is mainly used to detect whether a fire occurs in the battery cells inside the loading platform. If a fire occurs and the smoke sensor 23 receives a signal, it will send the fire signal to the controller, and the controller will issue corresponding instructions to immediately close the rolling door for fire extinguishing treatment.

[0034] The fire extinguishing system 2 further includes an infrared monitoring device 24, and the infrared monitoring device 24 is connected to the fireproof armor 21 and aligned with the loading and unloading positions of the loading platform body 1. The infrared monitoring device 24 is mainly used to monitor whether the battery cells in the automated storage and retrieval system are abnormal, and can also confirm the specific location where the fire occurs.

[0035] The present utility model also provides a stacker, including the fireproof structure of the above-mentioned stacker.

[0036] The fireproof structure of the stacker of the present utility model and the stacker. By directly fixing the fireproof cloth 5 on the reel 42, the winding diameter of the rolling shutter door is small, the occupied space is small, it is not deformed, the airtightness is good, and the standardization degree is high, which is suitable for storing goods of larger sizes; and only the reel 42 and the fireproof cloth 5 are fixedly connected, the installation structure is simple, the failure rate is reduced, and the installation and disassembly are more convenient; the rolling shutter is composed of a flexible fireproof cloth 5 (non-metal) with high temperature resistance, and there is basically no noise during winding, and at the same time, it is convenient to adjust the installation position, and it can be suitable for installing rolling shutters of different sizes, with wider adaptability; the reel bearing seat 44 and the reel motor 41 are both installed on the fixed frame, making the entire rolling shutter door modular and facilitating the overall installation and debugging of the rolling shutter door; the top protective cover 31 and the side protective cover 32 play a protective role for the fireproof cloth 5, making the rolling shutter door safer and tidier; the fireproof cloth 5 is wound in the direction of the outside of the frame, reducing the occupation of the internal space of the frame by the fireproof cloth 5, enabling the space range that can be blocked by the fireproof cloths 5 on both sides to be larger, and increasing the storage space for goods inside the frame.

[0037] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
