DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given. However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating directions or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0018] The embodiment discloses a rope-type self-induction fire extinguishing device, such as Figure 1-Figure 11 As shown, it includes a rope-type fire extinguishing member 1, such as Figure 1-Figure 3 As shown, in this embodiment, the rope-type fire extinguisher 1 is arranged inside the electrical cabinet 2 for self-induction fire extinguishing when the electrical components inside the electrical cabinet 2 catch fire. Specifically, the rope-type fire extinguisher 1 includes a sleeve 101 and a fire extinguishing agent 102 filled inside the sleeve 101; In this embodiment, the sleeve 101 is made of glass fiber material. The glass fiber material is used because the glass fiber sleeve rope is flexible and the position of the device can be reasonably arranged according to the shape of the electrical cabinet 2, thereby achieving the best fire extinguishing effect, and it occupies a small space and is flexible to install. In addition, the fire extinguishing agent 102 is filled inside the sleeve 101, and the fire extinguishing agent 102 is filled tightly, and both ends of the sleeve 101 are sealed; It should be noted that the fire extinguishing agent 102 is specifically a temperature-sensitive fire extinguishing agent. Specifically, in this embodiment, the injected fire extinguishing agent 102 uses thermosol particles and fluorine-containing microcapsule particles. The thermosol particles will produce a large amount of N2 and CO2 gas under certain temperature conditions, which can suffocate the protection space for fire extinguishing, while the fluorine-containing microcapsule particles will release fluorine-containing fire extinguishing agents 102 such as perfluorohexanone under certain temperature conditions, which can cool the environment space and extinguish the fire; Through the above-mentioned arrangement, during actual installation, the device can be linearly arranged inside the protected space, specifically in a snake shape. Then, after a fire occurs in the electrical cabinet 2, by setting the rope-shaped fire extinguishing device in the electrical cabinet 2, the fire extinguishing agent 102 can quickly sense the temperature change and generate fire extinguishing gas in the first time, thereby quickly extinguishing the fire, effectively eliminating the hidden danger of fire and avoiding the expansion of the accident.

[0019] A cabinet door 6 is provided at the front end of the electrical cabinet 2, and the rope-type fire extinguisher 1 can be installed inside the electrical cabinet 2 by means of a cable tie, and specifically presents a snake shape, so that the rope-type fire extinguisher 1 is evenly distributed inside the electrical cabinet 2, thereby performing multi-point triggering fire extinguishing inside the electrical cabinet 2.

[0020] Considering that in actual use, electrical components in the electrical cabinet 2, such as transformers, power filters, contactors, relays, etc., will generate heat when working. If the heat dissipation is poor, it will seriously affect the working state of the equipment. Therefore, if Figure 4 As shown, generally in the prior art, heat dissipation holes 3 are provided on the outer wall of the electrical cabinet 2 so that the electrical cabinet 2 can be cooled when the electrical cabinet 2 is in operation. When the rope-type fire extinguisher 1 is triggered, a large amount of N2 and CO2 gas is released, which can suffocate and extinguish the fire in the protection space. Considering that the heat dissipation holes 3 are provided on the outer wall of the electrical cabinet 2, the gas released by the rope-type fire extinguisher 1 may be discharged from the heat dissipation holes 3, thereby affecting the fire extinguishing effect. Furthermore, in this embodiment, Figure 1-Figure 2 As shown, a sealing member 4 is provided on the outer wall of the electrical cabinet 2, and a trigger member 5 is provided inside the electrical cabinet 2, so that when a fire occurs inside the electrical cabinet 2, after the rope-type fire extinguishing member 2 is triggered, the trigger member 5 can be triggered to control the sealing member 4 outside the electrical cabinet 2 to seal the heat dissipation hole 3, thereby sealing the interior of the electrical cabinet 2, preventing the gas released by the rope-type fire extinguishing member 1 from being discharged, and further improving the fire extinguishing effect.

[0021] Specifically, the blocking member 4 includes a blocking plate 401 and a clearance hole 402 arranged outside the electrical cabinet 2, wherein the blocking plate 401 can move longitudinally outside the electrical cabinet 2, and the heat dissipation hole 3 of the electrical cabinet 2 is covered or made way by the longitudinal movement of the blocking plate 401, thereby controlling the closing and opening of the heat dissipation hole 3, and the clearance hole 402 is used to make way for the heat dissipation hole 3 for smoke discharge; More specifically, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the blocking plate 401 is configured as a concave frame, which is mainly composed of a horizontal plate 411 arranged on the top of the electrical cabinet 2 and vertical plates 412 on both sides fixedly arranged below the horizontal plate 411, and the vertical plates 412 on both sides are respectively located on both sides of the electrical cabinet 2, and the inner side surfaces of the vertical plates 412 on both sides are in contact with the outer walls of the electrical cabinet 2 on both sides and slide in cooperation. It should be noted that in actual use, a sealing layer can be selected to be provided on the inner side surfaces of the vertical plates 412 on both sides, and then a sliding seal is achieved with the end surfaces of the two sides of the electrical cabinet 2 through the sealing layer, and the two sides are sealed. The side vertical plate 412 is also provided with a clearance hole 402 for making way for the heat dissipation holes 3 on both sides of the electrical cabinet 2. The clearance hole 402 penetrates the two side end surfaces of the vertical plate 412, so that the heat dissipation holes 3 on both sides of the electrical cabinet 2 can be ventilated through the clearance hole 402 when they overlap horizontally with the clearance hole 402. When the clearance hole 402 and the heat dissipation hole 3 are staggered with each other, the vertical plate 412 can block the heat dissipation hole 3 on one side, so that the heat dissipation hole 3 is closed, thereby preventing the smoke released by the rope-type fire extinguishing element 1 inside the electrical cabinet 2 from being discharged from the heat dissipation hole 3.

[0022] Correspondingly, a triggering member 5 is arranged inside the electrical cabinet 2, and the triggering member 5 includes a triggering rope 501, a winding rod 502 and a connecting rod 503. The triggering rope 501 is arranged inside the electrical cabinet 2, and the material of the triggering rope 501 is a material that melts when it encounters fire. The triggering rope 501 is arranged in a serpentine shape inside the electrical cabinet 2 in the same manner as the rope-type fire extinguishing member 1. Specifically, a winding rod 502 is fixedly arranged inside the panel of the electrical cabinet 2, and a plurality of winding rods 502 are arranged, and the plurality of winding rods 502 are arranged in a serpentine shape along the vertical and horizontal directions of the electrical cabinet 2, and the rope-type fire extinguishing member 1 and the triggering member 501 are arranged in a serpentine shape. The ropes 501 can be fixed on the multiple winding rods 502 by cable ties, so that the rope-type fire extinguishing element 1 and the trigger rope 501 are evenly distributed inside the electrical cabinet 2, so that the triggering positions of the rope-type fire extinguishing element 1 and the trigger rope 501 inside the electrical cabinet 2 cover a wider range. It should be noted that the trigger rope 501 and the rope-type fire extinguishing element 1 can be arranged front and back along the Z direction of the electrical cabinet 2 and are close to each other (not shown in the figure), so that when a fire occurs at a certain point inside the electrical cabinet 2, the same section of the trigger rope 501 and the rope-type fire extinguishing element 1 can be triggered in time to react; In addition, a connecting rod 503 is fixedly provided near the end of the trigger rope 501 and the top wall of the electrical cabinet 2, and the connecting rod 503 slides through the top wall of the electrical cabinet 2 and extends to the top of the outside of the electrical cabinet 2 and is fixedly connected to the cross plate 411 of the blocking plate 401, and the bottom end of the trigger rope 501 is fixedly connected to the bottom wall of the electrical cabinet 2, and the trigger rope 501 is in a taut state, and an elastic member 7 is arranged between the cross plate 411 and the top wall of the electrical cabinet 2, and the cross plate 411 of the blocking plate 401 is rebounded upward by the elastic member 7, and then the trigger rope 501 is in a taut state by the rebound of the elastic member 7, so that when a fire occurs inside the electrical cabinet 2, the trigger rope 501 is melted, so that the traction force of the trigger rope 501 on the cross plate 411 disappears, and then the elastic member 7 rebounds, so that the blocking plate 401 moves upward, and then the yield hole 402 can be controlled to be staggered with the heat dissipation hole 3, and then the heat dissipation hole 3 is covered and closed, thereby further improving the fire extinguishing effect of the rope-type fire extinguishing element 1.

[0023] Specifically, the elastic member 7 includes a limiting rod 701, an upper spring 702 and a limiting disk 703, wherein the limiting rod 701 is fixedly arranged on the top of the electrical cabinet 2, and a hole is provided on the horizontal plate 411 of the blocking plate 401 to be plugged and matched with the limiting rod 701, the limiting rod 701 is slidably plugged into the inside of the hole to be plugged and matched with the hole, and the upper spring 702 is sleeved on the outside of the limiting rod 701, and the upper spring 702 is located between the horizontal plate 411 and the top plate of the electrical cabinet 2, and the limiting disk 703 is fixedly arranged on one end of the limiting rod 701 located above the horizontal plate 411, and the upward movement of the horizontal plate 411 is limited by the limiting disk 703; It should be noted that, under normal conditions, the clearance hole 402 is overlapped and connected with the heat dissipation hole 3, and at this time, the elastic member 7 is compressed and the trigger rope 501 is taut. When the trigger rope 501 is melted, the top spring 702 causes the horizontal plate 411 to move upward. When the horizontal plate 411 contacts the limit plate 703, the clearance hole 402 is offset from the heat dissipation hole 3, and the clearance hole 402 is blocked by the vertical plate 412. In addition, a safety valve 17 is also installed on one side of the electrical cabinet 2. According to actual conditions, a matching size of the safety valve 17 is selected, and a plurality of safety valves 17 can also be provided. By providing the safety valve 17, so that when the internal pressure of the electrical cabinet 2 is relatively large and reaches the upper limit value, it can be automatically discharged. It should be noted that the safety valve 17 can be set as a safety pressure relief valve in the prior art, or it can be set as a pressure relief structure with the same principle as the safety pressure relief valve. For example, in other embodiments, a pressure relief hole can be opened on the outer wall of the electrical cabinet 2, and the pressure relief hole is covered and sealed by an elastic plate (equivalent to a valve flap). When the internal pressure increases to exceed the limited value, the elastic plate is opened to release the pressure. After the pressure returns to normal, the elastic plate continues to seal the pressure relief hole to prevent a large amount of internal fire extinguishing gas from leaking out.

[0024] In addition, considering that after the rope-type fire extinguisher 1 completes the fire extinguishing, a large amount of smoke will exist inside the electrical cabinet 2, and the sealed smoke inside the electrical cabinet 2 cannot be discharged quickly. If the staff directly opens the cabinet door 6 to discharge the smoke, a large amount of smoke will be discharged directly to the staff, which is not safe. In addition, when dealing with some electrical cabinets 2 with larger capacity, after the staff arrives at the scene, opening the cabinet door 6 and waiting for the smoke to be discharged will affect the maintenance efficiency. Therefore, in this embodiment, the blocking section of the vertical plate 412 is set to an active state, specifically, as Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the vertical plate 412 includes a fixed section 421 and a movable section 422, wherein the fixed section 421 is fixedly connected to the horizontal plate 411, and the clearance hole 402 is opened on the fixed section 421, the movable section 422 is arranged at the bottom of the fixed section 421, and the plug-in block 8 is fixedly arranged on the top of the movable section 422, and the bottom of the interior of the fixed section 421 is correspondingly provided with a plug-in groove 9, and the plug-in groove 9 runs through the lower end surface of the fixed section 421, and the plug-in block 8 is slidably plugged into the interior of the plug-in groove 9, and the outer wall of the plug-in block 8 is fitted with the inner wall of the plug-in groove 9, and the movable section 422 can move longitudinally below the fixed section 421 through the plug-in block 8 and the plug-in groove 9; It should be noted that, when the horizontal plate 411 rises to contact the limiting plate 703, the movable section 422 moves to one side of the heat dissipation hole 3 to cover and close it, that is, the movable section 422 is used to close the heat dissipation hole 3, and a rebound member 11 is further provided between the fixed section 421 and the movable section 422, and the rebound member 11 is used to rebound the movable section 422 downward. In addition, the movable section 422 and the fixed section 421 are also positioned by the positioning member 13; Specifically, a rebound member 11 is provided at the front and rear ends of the vertical plate 412, and the rebound member 11 includes a base plate 111, a base plate 2 112, a slide bar 113 and a lower top spring 114, wherein the base plate 111 is fixedly provided on the outer wall of the fixed section 421, and the base plate 2 112 is fixedly provided on the outer wall of the movable section 422, the slide bar 113 is fixedly provided on the bottom of the base plate 111, and the slide bar 113 passes through the base plate 2 112 and extends to the bottom of the base plate 2 112, a positioning plate 12 is fixedly provided on one end of the slide bar 113 located below the base plate 2 112, and the slide bar 113 is slidably plugged with the base plate 2 112, a lower top spring 114 is provided between the base plate 111 and the base plate 2 112, and the lower top spring 114 is sleeved on the outside of the slide bar 113, and then the movable section 422 can be moved downward by the lower top spring 114; The positioning member 13 includes a positioning rod 131, a positioning socket 132, a through hole 133 and a positioning plate 134, wherein a positioning socket 132 is provided at the top of the plug-in block 8, and the positioning socket 132 passes through the rear end face of the plug-in block 8, and correspondingly, a through hole 133 is provided at the rear end of the plug-in slot 9, and the through hole 133 is provided inside the fixed section 421, and the through hole 133 is arranged on the same axis as the positioning socket 132, and the positioning rod 131 is slidably inserted inside the through hole 133, and the two ends of the positioning rod 131 extend to the plug-in slot respectively. 9 and the rear end of the fixed section 421, one end of the positioning rod 131 located in the plug-in slot 9 is slidably plugged into the inside of the positioning hole 132, and the one end of the positioning rod 131 located at the rear end of the fixed section 421 is fixedly provided with a positioning plate 134, and the plug-in of the plug-in block 8 and the plug-in slot 9 is limited by the plug-in of the positioning rod 131, and it should be noted that when the positioning rod 131 is plugged into the inside of the positioning hole 132, the facing surfaces of the fixed section 421 and the movable section 422 are fitted to each other, and the lower top spring 114 is compressed; In addition, a through hole 10 is provided inside the plug-in block 8, and the through hole 10 passes through the two side end surfaces of the plug-in block 8. It should be noted that when the base plate 112 of the movable section 422 contacts the positioning plate 12, the through hole 10 and the heat dissipation hole 3 overlap laterally, and then the heat dissipation hole 3 is connected to the outside through the through hole 10 for smoke discharge; Therefore, after the fire is extinguished, when the smoke inside the electrical cabinet 2 needs to be discharged, the positioning rod 131 can be pulled out, and then the lower top spring 114 rebounds to make the movable section 422 move downward, so that the through hole 10 overlaps with the heat dissipation hole 3 for exhaust. In order to discharge the smoke from the heat dissipation hole 3 after the rope-type fire extinguisher 1 is released, and in order to avoid the power components from being unable to start due to the fire, the withdrawal of the positioning rod 131 is set to be driven by the electric drive component without the need for driving. In addition, the withdrawal of the positioning rod 131 needs to be delayed. Therefore, the movement of the positioning rod 131 is delayed by setting the delay control mechanism 14. like Figure 5 and Figure 8 As shown, the delay control mechanism 14 includes a slow rebound component 141 and a control component 142, wherein the slow rebound component 141 is used to slowly pull out the positioning rod, so that after the rope-type fire extinguishing element 1 is released and the fire extinguishing process is completed, the through hole 10 and the heat dissipation hole 3 are overlapped for exhaust, and the control component 142 is used to control the triggering of the slow rebound component 141, so that after the horizontal plate 411 moves up and the movable section 422 blocks the heat dissipation hole 3, the slow rebound component 141 is triggered again.

[0025] Specifically, Figure 5 , Figure 8-Figure 10As shown, the slow rebound component 141 includes a cylinder 1411, a piston 1412, a chamber 1413, a chamber 2 1414, a rebound shaft 1415, a rebound spring 1416, an oil circuit 1417 and a top plate 1418, wherein the cylinder 1411 is fixedly arranged on the outer wall of the fixed section 421, and the cylinder 1411 and the positioning plate 134 are on the same axis along the axial direction, and the piston 1412 is arranged in a sliding seal inside the cylinder 1411, and the interior of the cylinder 1411 is respectively separated by the piston 1412 with chamber 1413 and chamber 2 1414, the piston 1412 is facing the positioning plate 134 direction for chamber 1413, and the other direction for chamber 2 1414, and the piston 1412 is also fixedly arranged with a rebound shaft 1415 in the direction of the positioning plate 134, and the rebound The other end of the shaft 1415 passes through one end wall of the cylinder 1411 and extends to the outside of the cylinder 1411, and a top plate 1418 is fixedly provided at one end of the rebound shaft 1415 located outside the cylinder 1411, and the top plate 1418, the rebound shaft 1415 and part of the outer wall of the positioning plate 134 are on the same axis. In addition, there is a distance between the top plate 1418 and the positioning plate 134. In other words, when the top plate 1418 moves toward the positioning plate 134, it will contact the outer wall of the positioning plate 134 and push the positioning plate 134. A section of the outer wall of the rebound shaft 1415 located outside the cylinder 1411 is sleeved with a rebound spring 1416, and the rebound spring 1416 is located between the top plate 1418 and the end wall of the cylinder 1411. In addition, the chamber 1413 and the chamber 2 1414 are connected through the oil passage 1417. The oil circuit 1417 specifically includes a channel 1 4171 and a channel 2 4172, wherein the channel 1 4171 is provided on the piston 1412 and passes through both end surfaces of the piston 1412, the channel 1 4171 is used to connect the chamber 1 1413 with the chamber 2 1414, and a one-way flow direction is set at the channel 1 4171 through a one-way valve, and the specific flow direction is set to flow from the chamber 2 1414 toward the chamber 1 1413; The second channel 4172 is disposed on the outer wall of the cylinder 1411, and one end opening of the second channel 4172 is disposed in the first chamber 1413, and the other end opening is disposed in the second chamber 1414, so as to make the first chamber 1413 and the second chamber 1414 communicate with each other; In addition, it should be noted that when the rebound spring 1416 is fully released and unfolded, the top plate 1418 can push the positioning plate 134 and separate the positioning rod 131 from the positioning hole 132, thereby allowing the movable section 422 to move downward.

[0026] Through the above arrangement, under normal conditions, the rebound spring 1416 is compressed, and the control member 142 positions the top plate 1418. When the horizontal plate 411 moves upward, the movable section 422 closes the heat dissipation hole 3, and at the same time, the rope-type fire extinguishing member 1 inside the electrical cabinet 2 releases gas to extinguish the fire. At this time, the control member 142 is triggered to unlock the top plate 1418, and the rebound spring 1416 rebounds, so that the rebound shaft 1415 drives the piston 1412 to move toward the direction of chamber 1413 under the action of the rebound spring 1416. At the same time, when the piston 1412 moves, hydraulic oil is set inside the chamber 1413, and the hydraulic oil is squeezed by the piston 1412. The hydraulic oil flows from the second channel 4172 to the first channel 4171, so that when the piston 1412 moves, the hydraulic oil in the chamber 1413 can be damped, so that the piston 1412 moves slowly, and the top plate 1418 rebounds slowly, and the top plate 1418 moves slowly toward the positioning plate 134. It should be noted that a throttle valve 15 is also provided in the second channel 4172, and the moving speed of the piston 1412 can be adjusted by the throttle valve 15. In other words, the timing of overlapping communication between the through hole 10 and the heat dissipation hole 3 can be adjusted by the throttle valve 15 to ensure that the rope-type fire extinguishing element 1 releases gas, and then after the fire extinguishing process, the through hole 10 is connected with the heat dissipation hole 3 for smoke discharge; After the electrical cabinet 2 is repaired, the staff can reset the piston 1412. The reset movement of the piston 1412 can allow the oil in the chamber 2 1414 to re-enter the chamber 1 1413 through the channel 1 4171, and the top plate 1418 can be locked through the control part 142.

[0027] Specifically, Figure 8 and Fig.11 As shown, the control member 142 includes a locking rod 1421, a locking hole 1422, a pressure plate 1423, a return spring 1424, a fixing plate 1425 and a bottom plate 1426, wherein the locking rod 1421 is arranged below the top plate 1418, and a locking hole 1422 is provided on the outer circumferential outer wall of the top plate 1418 at a point at the bottom, and one end of the locking rod 1421 is inserted into the locking hole 1422, and in addition, a fixing plate 1425 is fixedly arranged on the outer wall of the fixing section 421, and the bottom end of the locking rod 1421 slides through the fixing plate 1425, and One end of the locking rod 1421 located at the bottom of the fixing plate 1425 is fixedly provided with a chassis 1426 for limiting, and a pressure plate 1423 is also fixedly provided on the outer wall of the locking rod 1421, and the pressure plate 1423 is arranged above the fixing plate 1425, and a return spring 1424 is also arranged between the pressure plate 1423 and the fixing plate 1425, and the return spring 1424 is sleeved on the outer wall of the locking rod 1421, and in addition, a connecting rope 16 is fixedly provided at the bottom of the chassis 1426, and the other end of the connecting rope 16 is fixedly connected to the outer wall of the electrical cabinet 2, and the connecting rope 16 is in a relaxed state; It should be noted that, when the horizontal plate 411 rises and contacts the limiting plate 703 , the connecting rope 16 is tightened and pulls the locking rod 1421 downward so that the locking rod 1421 is separated from the locking hole 1422 .

[0028] The present invention arranges the rope-type fire extinguishing element 1 in a serpentine shape inside the electrical cabinet 2, and then after a fire occurs in the electrical cabinet 2, the fire extinguishing agent 102 can quickly sense the temperature change and generate fire extinguishing gas in the first time. The injected fire extinguishing agent 102 uses thermosol particles and fluorine-containing microcapsule particles. The thermosol particles will generate a large amount of N2 and CO2 gas under certain temperature conditions, which can suffocate the protection space for fire extinguishing, while the fluorine-containing microcapsule particles will release fluorine-containing fire extinguishing agents 102 such as perfluorohexanone under certain temperature conditions, which can extinguish the surrounding The surrounding space is cooled and the fire is extinguished, so that the fire is quickly extinguished, the hidden danger of fire is effectively eliminated, and the expansion of the accident is avoided. In addition, the blocking member 4 and the trigger member 5 are arranged to cooperate with each other, so that when a fire occurs inside the electrical cabinet 2, the trigger rope 501 will be burned off. At this time, the traction force of the trigger rope 501 on the cross plate disappears, and the cross plate is bounced up by the action of the spring, so that the giving hole 402 is staggered with the heat dissipation hole 3, and then the heat dissipation hole 3 is closed, so as to prevent the gas released by the rope-type fire extinguishing component 1 from leaking from the heat dissipation hole 3, thereby improving the fire extinguishing effect of the rope-type fire extinguishing component 1.
