Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and more specifically, to a fire protection device. Background Technology

[0002] In recent years, Automated Guided Vehicles (AGVs) have been widely used in the warehousing and logistics industry due to their automatic and intelligent features, undertaking heavy-load and long-term material handling tasks. Currently, most mainstream AGVs on the market use lithium batteries as their power source. During operation, they continuously send their status (such as position, battery level, task completion status, fault information, etc.) to the control system. When their battery level drops to a certain point, the control system will arrange for them to automatically go to a charging station for "contactless charging" or "manual charging." However, during lithium battery charging, if there are problems such as short circuits or overcharging, there is a high risk of fire and explosion.

[0003] Therefore, in order to solve the above problems, fire prevention devices are often added to the area where the automated guided vehicles are charged. Specifically, when the automated guided vehicle is being charged, it is placed inside the fire prevention device. If a fire or explosion occurs, the fire prevention device will isolate the ignition source and ensure the safety of personnel and other items.

[0004] However, the relevant technology has at least one problem: the size of the existing fire protection device can only be adapted to the size of the actual automated guided vehicle, which reduces the versatility of the fire protection device. Utility Model Content

[0005] The technical problem solved by this invention is that the dimensions of existing fire protection devices can only be adapted to the actual dimensions of automated guided vehicles, which reduces the versatility of fire protection devices.

[0006] To address the aforementioned problems, this utility model provides a fireproof device, which includes a frame and fireproof components. The fireproof components cooperate with the frame to form a receiving space for enclosing mobile handling equipment. The frame includes multiple connecting plates and multiple support frames. At least one of the multiple support frames is detachably engaged with at least one of the multiple connecting plates.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: Specifically, fire protection devices in related technologies have fixed dimensions, making them difficult to adapt to different sizes of automated guided vehicles (AGVs), thus reducing their versatility. Therefore, this solution allows for the selection and assembly of different numbers and / or sizes of connecting plates and support frames according to actual needs, resulting in a frame of predetermined dimensions, thereby improving the versatility of the fire protection device. Furthermore, the frame in this solution is detachable, reducing the difficulty of handling and storage.

[0008] In one embodiment of this utility model, either the support frame or the adjacent connecting plate is provided with a snap-fit ​​protrusion, and the other is provided with a snap-fit ​​groove that mates with the snap-fit ​​protrusion.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: the structure of the snap-fit ​​protrusion and snap-fit ​​groove is simple, reducing the difficulty of assembling the frame.

[0010] In one embodiment of this utility model, a snap-fit ​​protrusion is disposed on the side of the support frame; a limiting angle is formed between the snap-fit ​​protrusion and the snap-fit ​​groove to restrict the connecting plate from disengaging; and / or a limiting angle is formed between the snap-fit ​​protrusion and the side to restrict the connecting plate from disengaging; and / or the snap-fit ​​protrusion includes a mating part and a limiting part, the mating part being used to mate with the snap-fit ​​groove, and the limiting part being formed at the end of the mating part away from the side; wherein, when the support frame and the connecting plate are snapped together, the connecting plate is clamped between the limiting part and the side.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: For example, the snap-fit ​​protrusion is set on the side of the support frame, and the snap-fit ​​groove is set at an angle to the horizontal installation direction of the connecting plate on the side of the connecting plate. When the connecting plate is adjusted and assembled to the side of the corresponding support frame, the snap-fit ​​groove is adapted to the snap-fit ​​protrusion, and under the action of the connecting plate's own weight, the snap-fit ​​between the connecting plate and the support frame is ensured.

[0012] In another example, the snap-fit ​​protrusion is angled upwards on the side of the support frame, so that the upper end of the snap-fit ​​protrusion forms an acute angle of less than 90 degrees with the side, while the lower end of the snap-fit ​​protrusion forms an obtuse angle of greater than 90 degrees with the side. Therefore, when the connecting plate is assembled to the corresponding side of the support frame, the snap-fit ​​groove fits onto the snap-fit ​​protrusion. Combined with the fit between the snap-fit ​​protrusion and the side, the weight of the connecting plate ensures a tight snap-fit ​​between the connecting plate and the support frame.

[0013] In another example, the snap-fit ​​protrusion consists of a mating part and a limiting part. During the assembly of the support frame and the mating connecting plate, the position of the connecting plate relative to the support frame is adjusted to ensure that the part of the connecting plate with the snap-fit ​​groove fits onto the mating part. At this time, due to the presence of the limiting part, the connecting plate is effectively prevented from coming off the snap-fit ​​protrusion. Furthermore, to ensure a tight fit between the connecting plate and the support frame, the limiting part extends towards the side so that the mating gap formed between the limiting part and the side is no greater than the thickness of the connecting plate, thereby ensuring that the connecting plate can be stably clamped between the side and the limiting part.

[0014] In one embodiment of this utility model, the fireproof component is made of a flexible fireproof material.

[0015] In one embodiment of this utility model, an assembly gap is formed between any two adjacent support frames; the fireproof component includes at least one fireproof part, which is used to encapsulate the corresponding assembly gap.

[0016] In one embodiment of this utility model, any support frame is provided with a plurality of first mating holes arranged at intervals from each other; the fireproof component is provided with a plurality of second mating holes at positions corresponding to the plurality of first mating holes; wherein, any first mating hole and the corresponding second mating hole are connected by a detachable connector.

[0017] Compared with existing technologies, the technical effect achieved by adopting this technical solution is to improve the flexibility of installing fireproof components onto the frame.

[0018] In one embodiment of this utility model, the fireproof component is integrally formed; or, the fireproof component is made of flexible fireproof materials of the same or different materials spliced ​​together.

[0019] In one embodiment of this utility model, two adjacent fireproof parts among a plurality of fireproof parts are defined as the first fireproof part and the second fireproof part; the first fireproof part is provided with a hook surface, and the second fireproof part is provided with a hook surface for adhering to the hook surface; or the first fireproof part and the second fireproof part are connected to the frame by adhesive; or the first fireproof part and the second fireproof part are connected by sewing; or the first fireproof part and the second fireproof part are fitted by overlapping; and / or a wire harness is provided on one side of the fireproof part located in the receiving space.

[0020] Compared with existing technologies, the technical effects achieved by this solution are as follows: the method of connecting multiple fireproof components through the use of hook and loop surfaces, stitching, or overlapping improves the flexibility of the fireproof components to the frame. Specifically, when a certain number of connecting plates and support frames are selected to fit the actual size of the automated guided vehicle, the number of fireproof components can be flexibly adjusted. In addition, the installation of the fireproof components to the frame by applying adhesive also improves the flexibility of assembly.

[0021] In one embodiment of this utility model, it further includes a fire extinguisher disposed within the frame; and / or an alarm disposed outside the frame; and / or a sensor disposed within the frame and electrically connected to the alarm.

[0022] In one embodiment of this utility model, the fireproof device further includes a rear plate, which is engaged with the support frame via a locking mechanism; and / or the rear plate has a cross-shaped cable pass through which the power supply line passes; and / or The fire protection device also includes a fire door and a control module that are electrically connected to each other. The fire door is movably installed at the assembly opening enclosed by the frame, and the control module is housed in the receiving space. The control module is used to control the fire door to open or close the assembly opening.

[0023] By adopting the technical solution of this utility model, the following technical effects can be achieved: Fire protection devices in related technologies have fixed dimensions, making them difficult to adapt to different sizes of automated guided vehicles (AGVs), thus reducing their versatility. Therefore, this technical solution allows for the assembly of connecting plates and support frames of varying quantities and / or sizes according to actual needs, resulting in a frame of predetermined dimensions and improving the versatility of the fire protection device. Furthermore, the frame in this technical solution is detachable, reducing the difficulty of handling and storage. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 This is a structural schematic diagram of a fire prevention device 100 provided in an embodiment of this utility model. Specifically, in conjunction with... Figures 2-8 The fireproof device 100 includes a frame 10 and fireproof components 20. The fireproof components 20 cooperate with the frame 10 to form a receiving space 11 for surrounding the mobile handling equipment. The frame 10 includes multiple connecting plates and multiple support frames 13. At least one of the multiple support frames 13 is detachably engaged with at least one of the multiple connecting plates. Specifically, fireproof devices in related technologies have fixed dimensions, making it difficult to adapt to different sizes of automated guided vehicles, thus reducing the versatility of the fireproof device. Therefore, in conjunction with this technical solution, different numbers and / or sizes of connecting plates and support frames 13 can be selected and spliced ​​according to actual needs to obtain a frame 10 of a preset size, thereby improving the versatility of the fireproof device 100. In addition, the frame 10 in this technical solution is detachable, reducing the difficulty of handling and storage.

[0028] Preferably, either the support frame 13 or the adjacent connecting plate is provided with a snap-fit ​​protrusion 131, and the other is provided with a snap-fit ​​groove 124 that mates with the snap-fit ​​protrusion 131. The structure of the snap-fit ​​protrusion 131 and the snap-fit ​​groove 124 is simple, which reduces the difficulty of assembling the frame 10.

[0029] Preferably, the snap-fit ​​protrusion 131 is connected to the side 132 of the support frame 13; a limiting angle is formed between the snap-fit ​​protrusion 131 and the snap-fit ​​groove 124 to restrict the connection plate from dislodging; and / or a limiting angle is formed between the snap-fit ​​protrusion 131 and the side 132 to restrict the connection plate from dislodging.

[0030] For example, the snap-fit ​​groove 124 has a first end and a second end that are disposed opposite to each other. The first end is closer to the top of the fireproof device 100 than the second end, and the second end extends to the side of the connecting plate in a direction away from the top, so as to form a snap-fit ​​opening into which the snap-fit ​​protrusion 131 extends.

[0031] The snap-fit ​​protrusion 131 includes a mating part and a limiting part. The mating part is used to mate with the snap-fit ​​groove 124, and the limiting part is formed at the end of the mating part away from the side 132. When the support frame 13 is snapped with the connecting plate, the connecting plate is sandwiched between the limiting part and the side 132.

[0032] For example, the snap-fit ​​protrusion 131 is obliquely upward on the side surface 132, so that the upper end of the snap-fit ​​protrusion 131 forms an acute angle of less than 90 degrees with the side surface 132, and conversely, the lower end of the snap-fit ​​protrusion 131 forms an obtuse angle of more than 90 degrees with the side surface 132. Thus, when the adjusting connecting plate is assembled to the side surface 132 of the corresponding support frame 13, the snap-fit ​​groove 124 is adapted to the snap-fit ​​protrusion 131. Combined with the mating relationship between the snap-fit ​​protrusion 131 and the side surface 132, under the action of the connecting plate's own weight, it is ensured that the connecting plate and the support frame 13 are tightly snapped together.

[0033] In another example, the snap-fit ​​protrusion 131 consists of a mating part and a limiting part. During the assembly of the support frame 13 and the mating connecting plate, the position of the connecting plate relative to the support frame 13 is adjusted to ensure that the part of the connecting plate with the snap-fit ​​groove 124 is fitted onto the mating part. At this time, due to the presence of the limiting part, the connecting plate is effectively prevented from coming off the snap-fit ​​protrusion 131. Furthermore, to ensure a tight fit between the connecting plate and the support frame 13, the limiting part extends towards the side 132 so that the mating gap formed between the limiting part and the side 132 is not greater than the thickness of the connecting plate, thereby ensuring that the connecting plate can be stably clamped between the side 132 and the limiting part.

[0034] Furthermore, the snap-fit ​​protrusion 131 can be made of one-piece steel. Of course, the snap-fit ​​protrusion 131 can also be composed of different materials, with the limiting part being elastic rubber. In another embodiment, the snap-fit ​​protrusion 131 can be integrally formed with the support frame 13. Of course, the snap-fit ​​protrusion 131 can also be screwed onto the support frame 13. Thus, the distance between the limiting part and the side 132 can be adjusted by adjusting the degree of screwing between the snap-fit ​​protrusion 131 and the support frame 13.

[0035] Preferably, the fireproof component 20 is made of a flexible fireproof material, such as ceramic fiber cloth, glass fiber cloth, ceramicized silicone rubber-glass fiber composite material, or other commercially available flexible fireproof materials.

[0036] Preferably, an assembly gap 14 is formed between any two adjacent support frames 13; the fireproof component 20 includes at least one fireproof part, which is used to encapsulate the corresponding assembly gap 14.

[0037] Preferably, each support frame 13 has a plurality of first mating holes spaced apart from each other; the fireproof component 20 has a plurality of second mating holes corresponding to the positions of the plurality of first mating holes; wherein, each first mating hole and the corresponding second mating hole are connected by a detachable connector. For example, the detachable connector may be a screw or a cable tie.

[0038] Preferably, the fireproof component 20 can be integrally molded. Of course, the fireproof component 20 can also be made of flexible fireproof materials of the same or different materials spliced ​​together.

[0039] Preferably, two adjacent fireproof parts among the multiple fireproof parts are defined as the first fireproof part and the second fireproof part; the first fireproof part is provided with a hook surface, and the second fireproof part is provided with a textured surface for adhering to the hook surface; or the first fireproof part and the second fireproof part are connected to the frame 10 by adhesive; or the first fireproof part and the second fireproof part are connected by stitching; or the first fireproof part and the second fireproof part are connected by overlapping, and the overlapping method can ensure the effectiveness of the fireproof material in blocking the ignition source; and / or the fireproof component 20 is provided with a cable tie on one side within the receiving space 11.

[0040] For example, by setting cable ties, it is easy to constrain the routing of wires inside the fire protection device 100. Specifically, the wires can be power supply lines and communication lines of charging devices that pass through the fire protection device 100.

[0041] Preferably, the fire protection device 100 includes a fire extinguisher 31 disposed within the frame 10; and / or, the fire protection device 100 includes a sensor disposed within the frame 10, and the sensor is electrically connected to an alarm. For example, the sensor may specifically be a smoke sensor and / or a temperature sensor; and / or, the fire protection device 100 includes an alarm 32 disposed outside the frame 10. For example, a hook 37 is provided at the top of the inner wall of the frame 10, and the fire extinguisher 31 is suspended in the receiving space 11 by the hook 37. The smoke sensor and / or temperature sensor are electrically connected to the alarm.

[0042] Preferably, the fireproof device 100 further includes a rear plate 38, which is engaged with the support frame 13 by a latch 33; and / or, the rear plate 38 has a cross-shaped cable pass 36 through which the power supply line passes. And / or, the fire protection device 100 also includes a fire door 34 and a control module that are electrically connected to each other. The fire door 34 is movably disposed at the assembly opening 35 enclosed by the frame 10, and the control module is disposed in the receiving space 11. The control module is used to control the fire door 34 to open or close the assembly opening 35.

[0043] In a specific example, the control module includes an electromagnetic suction module. When the electromagnetic suction module is powered on, it generates an electromagnetic force on the fire door 34, keeping the fire door 34 open to allow mobile handling equipment to enter and exit the assembly opening 35. When the smoke sensor or temperature sensor installed in the containment space 11 detects a fire inside the fire protection device 100, it controls the electromagnetic suction module to be de-energized. As a result, the fire door 34 closes the assembly opening 35 after losing the electromagnetic force, preventing the fire from spreading outward from the containment space 11.

[0044] Furthermore, to ensure that the fire door 34 can close the assembly opening 35 smoothly, a pulley group 39 is provided on the frame 10 at the position corresponding to the assembly opening 35 to cooperate with the fire door 34. Specifically, when the electromagnetic suction module is de-energized, the fire door 34 reduces the difficulty of closing the assembly opening 35 due to its own weight under the action of the pulley group 39.

[0045] In one specific embodiment, any of the support frames 13 has an inverted U-shaped structure. For ease of understanding, the connecting plate located at the front end of the fireproof device 100 is defined as the front end plate 121. The front end plate 121 cooperates with one of the support frames 13 located at the first end. The fire door 34 is located inside the front end plate 121. Considering the actual scenario where the fireproof device 100 is installed on the target ground, once a fire occurs inside the fireproof device 100, the fire door 34 will descend via the pulley block 39 until the lower end of the fire door 34 touches the ground. At this time, the upper end of the fire door 34 is at least partially blocked by the front end plate 121, thereby changing the containment space 11 into a relatively sealed space and limiting the spread of fire. In daily use, the front end plate 121 is also provided with an observation window 125 for easy observation of the situation inside the containment space 11.

[0046] Furthermore, the connecting plate located at the rear end of the fireproof device 100 among the multiple connecting plates is defined as the rear end plate 123. The rear end plate 123 cooperates with one of the multiple support frames 13 located at the tail end to form a rear plate 38. The rear end plate 123 has a cross-shaped cable pass 36 near its lower end for the power supply cable to pass through. Thus, by means of the cross-shaped cable pass 36, the power cable and / or communication cable can be guided into the receiving space 11. Then, a charging device that cooperates with the charging interface at the tail end of the mobile transport equipment can be installed in the receiving space 11. The mobile transport equipment can be charged by connecting the charging device with the power cable.

[0047] Based on the above, a fireproof component 20 is encapsulated on one side of the rear end plate 123 located within the receiving space 11. The fireproof component 20 is specifically a fireproof flexible material. Of course, the fireproof component 20 can also be a cover on the outer side of the rear end plate 123 facing away from the receiving space 11, or the fireproof component 20 can be wrapped around the rear end plate 123.

[0048] In another specific example, the rear panel 38 can also be composed of a support frame 13, a crossbar, and a fireproof component 20. Specifically, the fireproof component 20 is connected within the installation space enclosed by the support frame 13 and the crossbar.

[0049] To improve assembly efficiency and the firmness of the fireproof device 100 after assembly, a latch 33 is provided between the rear plate 38 and the adjacent support frame 13. The latch 33 specifically includes a mating plate and screws. The mating plate has a first screw hole for screwing into the support frame 13 and a second screw hole for screwing into the rear plate 38. Thus, the assembly is completed by screwing the mating plate, the rear plate 38 and the support frame 13 together with multiple screws.

[0050] Furthermore, the connecting plate located between the front end plate 121 and the rear end plate 123 among the multiple connecting plates is defined as a side plate 122, and multiple side plates 122 are arranged between multiple support frames 13. Among them, the fireproof component 20 is provided inside the inner surface of the frame 10, of course, the fireproof component 20 can also be covered on the outer surface of the frame 10.

[0051] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
