[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The protective structure disclosed in the present invention is mainly applied to the use of existing distribution boxes. If open flames or smoke appear inside the distribution box due to aging of the lines or other reasons, the staff will not be able to discover and cut off the power in time. The line equipment inside the distribution box will continue to burn, causing serious damage to the interior of the distribution box.

[0033] Reference Figure 1-Figure 4A protective structure includes a cutting protection component 1 and two bottom end seats 4. The cutting protection component 1 includes a placement plate 101, and the top of the placement plate 101 is fixedly connected to an upper rod 108. One side of the placement plate 101 is fixedly connected to a storage bag 109. The side walls of the placement plate 101 at both ends of the storage bag 109 are provided with limited sliding grooves 102. The insides of the two limited sliding grooves 102 are slidably connected to sliding rods 117, and the same side of the two sliding rods 117 is fixedly connected to a downward pressing link 116. The ends of the two downward pressing links 116 are fixedly connected to the same cutter. 110, two through holes 113 are opened on the storage cloth bag 109, and the cutter 110 passes through the two through holes 113. The top of the upper rod 108 above the downward pressure connecting rod 116 is fixedly connected to a top block 114, and the bottom of the top block 114 is fixedly connected to an electric telescopic rod 115, and the output end of the electric telescopic rod 115 is fixedly connected to the top of the downward pressure connecting rod 116. The bottom of the placement plate 101 is fixedly connected to two suspension rods 103, and the ends of the two suspension rods 103 are fixedly connected to the same cutting frame 104, and the cutting frame 104 is located directly below the cutter 110.

[0034] In a specific application scenario, when installing the cutting protection component 1, the cutter 110 and the grooving frame 104 are installed at the upper and lower ends of the line. During the use of the distribution box, the semicircular electric guide rail 106 drives the monitor 119 to rotate. When the monitor 119 detects an open flame or smoke inside the distribution box, the electric telescopic rod 115 drives the cutter 110 to slide down, and the storage bag 109 is cut open by the cutter 110. The fire extinguishing powder inside the storage bag 109 flows out to play an emergency fire extinguishing function. At the same time, the continuous downward pressure of the cutter 110 presses the line into the grooving frame 104, realizing the cutting operation, quickly cutting off the power, stopping the loss in time, and reducing the degree of damage to the electrical components inside the distribution box.

[0035] Specifically, after the cutter 110 cuts open the storage bag 109, the spring rod 105 is pulled to pull the outer part of the storage bag 109 upward to prevent the cut part of the storage bag 109 from blocking the spraying of the fire extinguishing powder. During the downward pressing process of the cutter 110, the spring arc plate 112 is pressed, so that the expansion spring rod 111 behind the spring arc plate 112 is compressed. When the cutter 110 is separated from the spring arc plate 112, the expansion spring rod 111 is reset to drive the spring arc plate 112 to deflect upward, thereby lifting the fire extinguishing powder on the spring arc plate 112 and sprinkling it to various positions inside the distribution box, thereby increasing the coverage range of the fire extinguishing powder and thus improving the fire extinguishing effect.

[0036] It should be noted that the monitor 119 is driven to rotate back and forth by the semicircular electric guide rail 106, thereby increasing the monitoring range of the monitor 119 and ensuring that when an open flame or smoke occurs, the monitor 119 can detect it in the first time, thereby improving the emergency treatment effect. At the same time, the operation of the monitor 119, the electric telescopic rod 115 and the semicircular electric guide rail 106 in the cut-off protection component 1 are all powered by the external electrical box 2, avoiding the situation where insufficient power supply and inability to operate are caused by damage to the distribution box.

[0037] Reference Figure 1-Figure 3 In a preferred embodiment, the placement plate 101 is located on one side of the storage bag 109 and is equidistantly connected to a spring-loaded arc plate 112 through a hinge, and each spring-loaded arc plate 112 is equidistantly fixedly connected to the side of the placement plate 101 facing the placement plate 101. One end of the deployment spring rod 111 is fixedly connected to one side of the placement plate 101, and a pulling spring rod 105 is equidistantly fixedly connected to one side of the upper rod 108. One end of the pulling spring rod 105 is fixedly connected to the outer side wall of the storage bag 109 near the bottom. Fire extinguishing powder is stored between the placement plate 101 and the storage bag 109. Both ends of the top of the upper rod 108 are fixedly connected to mounting rods 107, and the ends of the two mounting rods 107 are fixedly connected to the same semicircular electric guide rail 106. The interior of the semicircular electric guide rail 106 is slidably connected to an electric slider 118. One side of the electric slider 118 is fixedly connected to a mounting ring plate 120, and a monitor 119 is fixedly connected to the mounting ring plate 120.

[0038] Reference Figure 1 and Figure 4 In a preferred embodiment, the side of the placement plate 101 facing away from the storage bag 109 is fixedly connected to the external electrical box 2, and the placement plate 101 is fixedly connected to the docking tube 6 at both ends of the external electrical box 2. The docking tube 6 is in contact with the bottom end seat 4. The same positioning column 7 is inserted into the inside of the docking tube 6 and the bottom end seat 4. The top of the positioning column 7 is fixedly connected to the upper clamping frame 3, and a positioning slide groove is opened on one side of the bottom end seat 4. The lower clamping frame 5 is slidably connected to the inside of the positioning slide groove, and the upper clamping frame 3 and the lower clamping frame 5 are staggered and clamped.

[0039] Reference Figure 5-10 A distribution box includes the protective structure described above, and also includes a box body 8. External connection holes are opened on both sides of the box body 8 near the top. Exhaust frames 9 are fixedly connected to the inside of the two external connection holes. A connecting hole is opened at the bottom of the exhaust frame 9. Exhaust blades 12 are connected to the inner walls of both sides of the exhaust frame 9 at the connecting hole at equal distances through bearings.

[0040] Reference Figure 5 、 Figure 9 and Figure 10In a preferred embodiment, two external holes are opened on both sides of the box body 8 below the exhaust frame 9, and the two external holes are provided with a dust-proof and moisture-proof air intake group 10, and the dust-proof and moisture-proof air intake group 10 includes an air intake circular frame 1001, and the air intake circular frame 1001 is fixedly connected to the inside of the external hole 2. The open end of the air intake circular frame 1001 away from the box body 8 is fixedly connected to a sealing plate 1002, and the open end of the air intake circular frame 1001 close to the box body 8 is fixedly connected to a dust filter screen plate 1008, and one side of the sealing plate 1002 is fixedly connected to a drive motor 1005, and the output shaft of the drive motor 1005 is fixedly connected to a rotating shaft 1009 through a coupling, and the outer wall of the rotating shaft 1009 is equidistantly provided with elastic brush rods 1007, and the elastic brush rod 1 007 is in contact with the dust filter screen plate 1008, and the side of the sealing plate 1002 facing the elastic brush plate is fixedly connected with a matching impact arc plate 1012, and the matching impact arc surface is in contact with the dust filter screen plate 1008. The outer wall of the air inlet circular frame 1001 facing downward is provided with a dust collecting hole, and the inside of the dust collecting hole is fixedly connected with a dust collecting box 1004. The air inlet circular frame 1001 is provided with two adapter holes in the middle, and the inside of the two adapter holes are fixedly connected with a hollow connecting frame 1003, and the top of the hollow connecting frame 1003 is provided with a plug hole, and the inside of the plug hole is plugged with a water absorption plate 1006, and the top of the water absorption plate 1006 is fixedly connected with a pull rod 1010, and the hollow connecting frame 1003 is provided with air inlet holes 1011 on both sides of the water absorption plate 1006.

[0041] Specifically, during the daily operation of the distribution box, the external gas enters the hollow connecting frame 1003 through the air inlet 1011, and the water absorption plate 1006 inside the hollow connecting frame 1003 absorbs the water vapor carried in the gas. The gas then enters the air inlet circular frame 1001, and the dust filter plate 1008 filters the dust carried by the gas, thereby ensuring that the gas entering the distribution box is clean and dry gas, avoiding the gas carrying water vapor and dust to pollute the electrical components inside the distribution box, and avoiding the occurrence of such safety accidents.

[0042] It should be noted that the dust-proof and moisture-proof air intake group 10 starts the drive motor 1005 at regular intervals, and the drive motor 1005 drives each elastic brush rod 1007 to brush the dust attached to the dust filter screen 1008. When the rotating elastic brush rod 1007 carries dust and contacts the cooperating impact arc plate 1012, the impact between the two causes the elastic brush rod 1007 to elastically deform, and the dust carried on it falls off during the impact and vibration process, and the fallen dust gradually falls into the dust collecting box 1004 below, thereby extending the service life of the dust filter screen 1008. At the same time, after the water absorption plate 1006 has been used for a period of time, the staff can directly remove it from the hollow connecting frame 1003 through the pull rod 1010 and replace it, which is convenient and quick.

[0043] Reference Figure 5 、 Figure 7 and Figure 8 In a preferred embodiment, side protection assemblies 11 are provided on both sides of the box body 8 near the bottom end, and the side protection assemblies 11 include protective bent plates 1101, two shafts 1109 are fixedly connected to both sides of the box body 8, and the opposite sides of the two shafts 1109 on one side are connected to the same deflection shaft 1102 through bearings, and the protective bent plates 1101 are fixedly connected to the outer side walls of the deflection shaft 1102, and a buffer spring rod 1110 is fixedly connected to the side of the protective bent plate 1101 facing the box body 8 at equal distances, and one end of the buffer spring rod 1110 is fixedly connected to one side of the box body 8, and follower rods 1105 are fixedly connected to both sides of the protective bent plate 1101, and the ends of the two follower rods 1105 are fixedly connected to the side pressure plates 1113, and the protective bent plate 1101 faces A fixing rod 1107 is fixedly connected to the arc surface of the box body 8, an integration rod 1106 is fixedly connected to one side of the fixing rod 1107, an extrusion cylinder 1108 is fixedly connected to the side of the integration rod 1106 facing the box body 8 at an equal distance, a protective airbag 1104 is fixedly connected to the side of the box body 8 close to the extrusion cylinder 1108, an exhaust hole is opened on one side of the protective airbag 1104, an exhaust pipe 1112 is fixedly connected to the inside of the exhaust hole, an outer wall of the exhaust pipe 1112 is connected to an air valve 1114 through a flange, one side of one of the shafts 1109 is fixedly connected to a pump stand 1111, an air pump 1103 is fixedly connected to the pump stand 1111, an air delivery end of the air pump 1103 is fixedly connected to an air guide pipe 1115, one end of the air guide pipe 1115 is inserted into the inside of the protective airbag 1104.

[0044] Specifically, if the side of the distribution box is hit during use, the impactor will first hit the protective bent plate 1101. The protective bent plate 1101 will deflect under the action of the impact, and the buffer spring rod 1110 will play a role of single-layer buffering protection. When the extrusion cylinders 1108 at the upper end of the protective bent plate 1101 are squeezed onto the protective airbag 1104, the protective airbag 1104 will play a double-layer buffering protection. The double buffering reduces the impact damage to the distribution box caused by the impactor, thereby protecting the distribution box.

[0045] It should be noted that when the extrusion cylinder 1108 squeezes the middle position of the protective airbag 1104, the gas inside the protective airbag 1104 flows toward both ends, and the flowing gas causes the two ends of the protective airbag 1104 to bulge. During the deflection of the protective bent plate 1101, the side pressure plate 1113 pushes the two ends of the bulging protective airbag 1104, so that the two ends of the protective airbag 1104 are covered toward the other two surfaces of the box 8, thereby increasing the protection range of the protective airbag 1104.

[0046] Working principle: During use, when installing the cut-off protection component 1, place the placement plate 101 in the reserved hole opened on the box body 8. After the placement plate 101 is placed, insert the positioning column 7 into the docking tube 6 and the bottom end seat 4. The bottom end seat 4 is fixedly connected to the box body 8. Then slide the lower clip frame 5 into the positioning slide groove to complete the docking between the lower clip frame 5 and the upper clip frame 3, that is, complete the installation of the cut-off protection component 1. During normal use of the distribution box, the external gas enters the hollow connection frame 1003 through the air inlet hole 1011, and the water absorption plate 1006 inside the hollow connection frame 1003 absorbs the water vapor carried in the gas. The gas then enters the air inlet circular frame 1001, and the dust filter plate 1008 filters the dust carried by the gas, thereby ensuring that the gas entering the distribution box is The body is clean and dry gas, and the gas inside the distribution box is discharged through the gaps between the exhaust blades 12 to complete the heat dissipation operation inside the distribution box. At the same time, the semicircular electric guide rail 106 drives the monitor 119 to rotate back and forth, thereby improving the monitoring range of the monitor 119 and ensuring that when an open flame or smoke occurs, the monitor 119 can detect it at the first time. When the monitor 119 detects an open flame or smoke inside the distribution box, the electric telescopic rod 115 drives the cutter 110 to slide down, and the storage bag 109 is cut open by the cutter 110, and the fire extinguishing powder inside the storage bag 109 flows out to play an emergency fire extinguishing function. At the same time, the continuous downward pressure of the cutter 110 presses the line into the cutting groove frame 104, realizing the cutting operation, quickly cutting off the power, and realizing emergency processing before the staff arrives.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
