Description

Technical Field

[0001] This invention relates to the field of fire safety technology, and in particular to a passive active fire protection device based on microencapsulation of perfluorohexanone. Background Technology

[0002] With the rapid development of new energy power generation, smart grids and data centers, power distribution cabinets, as key equipment for power distribution and management, have integrated energy storage batteries, which have become a common configuration for achieving power buffering, uninterrupted power supply and peak load management. However, lithium-ion batteries are prone to thermal runaway under conditions such as overcharging, over-discharging, internal short circuits or mechanical abuse, which can cause fires or even explosions, posing a serious threat to the safe and stable operation of power distribution systems.

[0003] Currently, perfluorohexanone fire extinguishing agent is mostly used for fire protection of energy storage batteries inside distribution cabinets. In practical applications, fire extinguishing patches containing perfluorohexanone are usually applied to the outside of the battery bracket to form a covering for the battery pack, so that the fire extinguishing agent can be released when a fire occurs.

[0004] However, perfluorohexanone fire extinguishing patches require regular inspection and replacement during actual use. If they are found to be ineffective or substandard, they must be replaced in time. The existing installation method mostly uses adhesive to fix the fire extinguishing patch directly to the surface of the bracket. Although the installation is convenient, it brings certain problems to the later maintenance. Maintenance personnel often need to apply a lot of external force during the disassembly process, and the small gap between the battery and the bracket makes the operation inconvenient, which makes the replacement and disassembly work difficult for the staff. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that it is difficult to replace the existing perfluorohexanone fire extinguishing patch that is adhered to the battery holder.

[0006] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a self-sensing active fire prevention device based on perfluorohexanone microencapsulation, which includes a storage bracket.

[0007] A crossbeam is fixedly connected to the storage bracket, and the crossbeam is arranged parallel to the long axis of the storage bracket.

[0008] The mounting component includes a mounting plate and a buckle for fixing the mounting plate. The buckle engages with the edge of the crossbeam, and a fire extinguishing sticker is adhered to the surface of the mounting plate.

[0009] The pressing component includes a connecting rope connected to the buckle and a pressure sleeve connected to the end of the connecting rope;

[0010] The movement of the pressure sleeve can cause the end of the buckle connected to the connecting rope to deform, thereby realizing the separation between the buckle and the crossbeam.

[0011] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: the crossbeam includes a notch formed in its side wall and an edge portion that is inlaid in the inner wall of the crossbeam;

[0012] The buckle includes a bent portion formed therein and a connecting portion adapted to the edge portion;

[0013] The connecting part abuts against the edge part, thereby fixing the buckle to the crossbeam.

[0014] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation of the present invention: the buckle is squeezed by the edge portion and bent inward along the bending portion;

[0015] The number of mounting components is multiple sets, and the multiple sets of mounting components cover the outer perimeter of the battery pack.

[0016] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: a through hole is provided on the side wall of the connecting part;

[0017] The pressure sleeve includes a first housing and a second housing that cooperates with the first housing, and the first housing and the second housing are detachably connected;

[0018] The number of connecting ropes is one set, and the connecting ropes of the set are symmetrically arranged on both sides of the pressure sleeve.

[0019] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: the connecting rope includes a first limiting block and a second limiting block respectively disposed at its two ends;

[0020] The second limiting block is located between the first housing and the second housing;

[0021] The first limiting block abuts against the inner wall of the through hole, and the connecting rope passes through the through hole and extends to its outer side.

[0022] In a preferred embodiment of the self-sensing active fire suppression device based on perfluorohexanone microencapsulation described in this invention: the pressure sleeve moves toward the mounting plate, and the connecting rope can pull the buckle sidewall to bend and deform toward the center position.

[0023] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: a push rod is sleeved in the center of the second housing;

[0024] The push rod and the pressure sleeve are in a sliding fit;

[0025] The push rod is provided with an elastic element at one end, and the other end of the push rod abuts against the first housing.

[0026] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: the push rod can have a certain gap with the buckle.

[0027] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: the pressure sleeve can push the push rod to abut the buckle, and the pressure sleeve can compress the elastic element under the reverse force of the buckle;

[0028] The elastic element is compressed and pushes the push rod to move synchronously with the pressure sleeve;

[0029] The push rod pushes the buckle away from the inside of the crossbeam.

[0030] In a preferred embodiment of the self-sensing active fire prevention device based on perfluorohexanone microencapsulation described in this invention: the notch facilitates the tool to penetrate to the inside of the crossbeam so that the tool abuts against the pressure sleeve.

[0031] The beneficial effects of this invention are as follows: by connecting the connecting rope to the connecting part, the maintenance personnel can push the pressure sleeve to move closer to the mounting plate. The movement of the pressure sleeve can pull the connecting rope to move, and the movement of the connecting rope can drive the side wall of the buckle to bend inward, thereby releasing the fixation between the buckle and the crossbeam. This makes it easier for the maintenance personnel to disassemble the mounting plate and replace the perfluorohexanone patch. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0041] Reference Figures 1-6 This embodiment provides a self-sensing active fire prevention device based on perfluorohexanone microencapsulation, including a storage bracket 1 and a crossbeam 2, which are fixedly connected to the storage bracket 1. The crossbeam 2 is arranged in a direction parallel to the long axis of the storage bracket 1.

[0042] It should be noted that the storage bracket 1 is made of aluminum alloy and is fixedly installed inside the power distribution cabinet, mainly for supporting the energy storage battery; the storage bracket 1 has a rectangular structure, the crossbeam 2 is formed by bending a metal mounting plate, and the crossbeam 2 is fixedly connected to the storage bracket 1 by bolts, and the crossbeam 2 is set along the long axis of the storage bracket 1.

[0043] Furthermore, the mounting component 3 includes a mounting plate 31 and a buckle 32 fixedly connected to the mounting plate 31. The buckle 32 engages with the edge of the crossbeam 2, and a fire extinguishing sticker is adhered to the surface of the mounting plate 31.

[0044] It should be noted that the mounting plate 31 and the buckle 32 are fixedly connected by bolts, and the mounting plate 31 is a metal mounting plate with good bending deformation capability; the buckle 32 is engaged with the edge of the crossbeam 2, thereby fixing the position between the buckle 32 and the crossbeam 2, thus fixing the mounting plate 31 to one side of the crossbeam 2.

[0045] Specifically, the mounting plate 31 and the clip 32 are fixedly connected by bolts, and the mounting plate 31 is a metal mounting plate with good performance. The surface of the mounting plate 31 away from the clip 32 is bonded with perfluorohexanone fire extinguishing tape by adhesive, and the adhesive can ensure that the perfluorohexanone fire extinguishing tape does not detach from the mounting plate 31 under high temperature conditions; moreover, the cost of the mounting plate 31 is low, and when the fire extinguishing tape needs to be replaced, the mounting plate 31 and the perfluorohexanone fire extinguishing tape can be replaced at the same time.

[0046] Furthermore, the pressing component 4 includes a connecting rope 41 connected to the buckle 32 and a pressure sleeve 42 connected to the end of the connecting rope 41; the movement of the pressure sleeve 42 can pull the end of the buckle 32 connected to the connecting rope 41 to deform, thereby realizing the separation between the buckle 32 and the crossbeam 2.

[0047] It should be noted that the buckle 32 is connected to the connecting rope 41. The buckle 32 can be bent and deformed by moving the connecting rope 41, so that the buckle 32 can be separated from the inner wall of the crossbeam 2. This makes it easier for workers to remove the mounting plate 31 from the side wall of the crossbeam 2.

[0048] Specifically, the connecting rope 41 is connected to the pressure sleeve 42. Maintenance personnel can push the pressure sleeve 42 to drive the connecting rope 41 to pull the side wall of the buckle 32 to the center position, thereby achieving the separation between the buckle 32 and the crossbeam 2.

[0049] When staff need to replace the expired perfluorohexanone fire extinguishing patch during the inspection, they can use a thin tool to push the pressure sleeve 42 towards the mounting plate 31. The movement of the pressure sleeve 42 can pull the connecting rope 41 and cause the side wall of the buckle 32 to bend towards the center position, thereby separating the buckle 32 from the crossbeam 2, which makes it easier for maintenance personnel to remove the perfluorohexanone patch.

[0050] After disassembly, a new perfluorohexanone patch is installed, and the clip 32 is pushed close to the crossbeam 2, causing the inner wall of the end of the crossbeam 2 to press the side wall of the clip 32 inward, so that the clip 32 can enter the inner side of the crossbeam 2. Then, as the clip 32 continues to enter the inner side of the crossbeam 2, the clip 32 and the side wall of the crossbeam 2 engage and lock together, thus forming a fixed connection between the clip 32 and the crossbeam 2, thereby completing the replacement of the new perfluorohexanone patch.

[0051] Reference Figures 1-6 As an optional embodiment, the crossbeam 2 includes a notch 21 formed in its side wall and an edge portion 22 that is fastened to the inner wall of the crossbeam 2; the buckle 32 includes a bent portion 321 formed inside it and a connecting portion 322 that is adapted to the edge portion 22; the connecting portion 322 abuts against the edge portion 22, thereby fixing the buckle 32 to the crossbeam 2.

[0052] Furthermore, the notch 21 allows the tool to penetrate to the inside of the crossbeam 2 so that the tool comes into contact with the pressure sleeve 42.

[0053] It should be noted that the cross-section of the beam 2 is a rectangular structure with one side facing the opening, and the end of the beam 2 facing the opening is provided with an edge portion 22, the cross-section of the edge portion 22 is an arc-shaped surface; in order to facilitate maintenance personnel to use tools to push the pressure sleeve 42 to move, a notch 21 is also provided on the side wall of the beam 2, through which the tool can be made to contact the surface of the pressure sleeve 42.

[0054] The buckle 32 is composed of a bottom straight plate and two side inclined plates. A bending part 321 is provided at the connection between the straight plate and the inclined plate. When the maintenance personnel push the pressure sleeve 42 to drive the connecting rope 41 to pull the side wall of the buckle 32 to bend, the side wall of the buckle 32 can deform along the bending part 321.

[0055] Specifically, the connecting part 322 is located at the end of the inclined plate of the buckle 32, and the connecting part 322 is bent outward to form a "C" shaped curved surface; and the connecting part 322 can cooperate with the edge part 22 of the opening section of the crossbeam 2 to fix the position between the buckle 32 and the crossbeam 2.

[0056] Furthermore, the buckle 32 is pressed by the edge portion 22 and bent inward along the bending portion 321; there are multiple sets of mounting parts 3, and multiple sets of mounting parts 3 cover the outer periphery of the battery pack.

[0057] It should be noted that when the buckle 32 is installed on the inner side of the crossbeam 2, the buckle 32 is squeezed by the edge part 22, so that the side wall of the buckle 32 can be bent and deformed along the position of the bending part 321 to reduce the opening size of the buckle 32 and ensure that the buckle 32 can be moved to the inner side of the crossbeam 2.

[0058] Specifically, there are multiple sets of mounting components 3, all of which are fitted with the crossbeam 2 and fixed at the outer edge of the battery to form a battery enclosure; in the event of a fire, the perfluorohexanone fire extinguishing patch can respond quickly.

[0059] Furthermore, the connecting part 322 has a through hole 323 on its side wall; the pressure sleeve 42 includes a first housing 421 and a second housing 422 that cooperates with the first housing 421, and the first housing 421 and the second housing 422 are detachably connected; the number of connecting ropes 41 is one set, and the set of connecting ropes 41 are symmetrically arranged on both sides of the pressure sleeve 42.

[0060] It should be noted that, in order to facilitate the connection between the connecting rope 41 and the buckle 32, a through hole 323 is provided at the position of the connecting part 322, and a knot is provided at one end of the connecting rope 41 to fix the position between the connecting rope 41 and the buckle 32; the other end of the connecting rope 41 is fitted with the pressure sleeve 42. The first housing 421 and the second housing 422 are both formed by mold casting, and the first housing 421 and the second housing 422 are connected by bolts. The connecting rope 41 can be pressed between the first housing 421 and the second housing 422 by bolts.

[0061] Furthermore, the connecting rope 41 includes a first limiting block 411 and a second limiting block 412 respectively disposed at its two ends; the second limiting block 412 is located between the first housing 421 and the second housing 422; the first limiting block 411 abuts against the inner wall of the through hole 323, and the connecting rope 41 passes through the through hole 323 and extends to its outer side.

[0062] It should be noted that a first limiting block 411 is fixedly provided at one end of the connecting rope 41, and a second limiting block 412 is fixedly provided at the other end. The first limiting block 411 is located inside the through hole 323. The second limiting block 412 is fixed between the first housing 421 and the second housing 422. Since the length of the connecting rope 41 is fixed and the pressure sleeve 42 is connected to the two connecting ropes 41, the connecting rope 41 is in a taut state under normal conditions.

[0063] Furthermore, as the pressure sleeve 42 moves closer to the mounting plate 31, the connecting rope 41 can pull the side wall of the buckle 32 to bend and deform towards the center position.

[0064] It should be noted that maintenance personnel use tools to push the pressure sleeve 42 towards the mounting plate 31. The movement of the pressure sleeve 42 can simultaneously pull the connecting rope 41, and the pulling of the connecting rope 41 can cause the side wall of the buckle 32 to bend inward along the bending part 321; thus reducing the opening of the buckle 32 to release the fixation between the buckle 32 and the crossbeam 2.

[0065] Reference Figures 1-6 In one embodiment provided in this application, a push rod 43 is sleeved in the center of the second housing 422; the push rod 43 is slidably engaged with the pressure sleeve 42; an elastic element 44 is provided at the end of the push rod 43, and the other end of the elastic element 44 abuts against the first housing 421.

[0066] It should be noted that the push rod 43 has a hollow internal structure and slides between the push rod 43 and the pressure sleeve 42; the elastic element 44 is a spring, and the elastic potential energy released by the elastic element 44 can push the push rod 43 to move away from the pressure sleeve 42 in the opposite direction.

[0067] Furthermore, there is a certain gap between the push rod 43 and the latch 32.

[0068] It should be noted that, in order to avoid the push rod 43 and the buckle 32 from colliding at the beginning of the movement of the pressure sleeve 42, there is a certain gap between the push rod 43 and the buckle 32; this gap is sufficient to push the push rod 43 to collide with the buckle 32 only after the pressure sleeve 42 moves a certain distance toward the mounting plate 31.

[0069] Furthermore, the pressure sleeve 42 can push the push rod 43 to abut against the buckle 32, and the pressure sleeve 42 can compress the elastic element 44 under the reverse force of the buckle 32; the elastic element 44 is compressed and pushes the push rod 43 to move synchronously with the pressure sleeve 42; the push rod 43 pushes the buckle 32 away from the inside of the crossbeam 2.

[0070] It should be noted that during the process of the pressure sleeve 42 moving towards the mounting plate 31 under the thrust, the connecting rope 41 can be pulled along as the pressure sleeve 42 moves. The connecting rope 41 can drive the side wall of the buckle 32 to bend towards the center position. As the bending deformation of the side wall of the buckle 32 increases, the end of the push rod 43 begins to abut against the buckle 32. The end of the push rod 43 is limited by the buckle 32, so that the movement of the pressure sleeve 42 can push the push rod 43 to compress the elastic element 44 inward. When the connecting part 322 is completely separated from the crossbeam 2, the position of the buckle 32 will no longer be restricted. At this time, the elastic element 44 releases elastic potential energy and can push the buckle 32 to move away from the crossbeam 2, thereby realizing the separation between the buckle 32 and the crossbeam 2.

[0071] After the maintenance personnel release the limit between the buckle 32 and the crossbeam 2, they can continue to use tools to push the pressure sleeve 42 to move. At this time, the pressure sleeve 42 moves synchronously with the push rod 43, and then the tool can be used to push the push rod 43 to push the mounting plate 31 away from the crossbeam 2; the buckle 32 can be unlocked by pushing the pressure sleeve 42 to move.

[0072] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.

[0073] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
