Description

Technical Field

[0001] The present invention relates to the technical field of cable sealing, and more particularly to a cable fireproof sealing device. Background Art

[0002] A cable fireproof sealing device is a sealing device used when multiple groups of cables pass through walls or roofs. For example, if a cable catches fire in one room, this sealing device can prevent the spread of the cable fire, prevent the fire from spreading to other areas after the cable catches fire, and reduce fire losses. Cable fireproof sealing devices are widely used in fields such as electricity, construction, chemical industry, and transportation, and are essential for daily electricity use safety;

[0003] During the daily use of existing cable fireproof sealing devices, the cable fireproof sealing devices will reserve multiple holes for direct use when adding cables. To prevent some rubber tubes or woolen cloth from being stuffed into the reserved cable holes for sealing when not in use, during the sealing process, the holes will not be used for a long time, and the sealing material will adhere to the inner wall of the holes. The cleaning process is not only cumbersome, but also easily causes damage to the inner wall of the holes, and easily scratches the cables, affecting the service life of the cables;

[0004] During the daily use of existing cable fireproof sealing devices, when a fire breaks out and the combustion temperature remains high due to a large fire, the outer protective sleeve of the cable will melt due to continuous high-temperature combustion. The cable holes inside the cable fireproof sealing device will also lack a sealing device, resulting in the leakage and diffusion of harmful gases generated by combustion through the hole gaps left by the cables, thus affecting the safety of the users. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable fireproof sealing device to solve the problems existing in the above-mentioned background art.

[0006] The present invention provides the following technical solutions: A cable fireproof sealing device includes a main body housing. A cable duct is movably sleeved inside the main body housing. A flame-retardant rubber tube is movably sleeved inside the cable duct. An arc-shaped metal rod is movably sleeved inside the flame-retardant rubber tube. One end of the arc-shaped metal rod is fixedly connected to an octagonal nut. The other end of the arc-shaped metal rod is fixedly connected to a left outer turntable. A rotary closing plate is movably sleeved inside the left outer turntable. A rotating bearing is movably sleeved outside the rotary closing plate. A right outer turntable is movably sleeved outside the rotary closing plate. An electromagnetic ultrasonic sensor is provided outside the right outer turntable.

[0007] Further, a pipe plugging block is fixedly connected to the outside of the electromagnetic ultrasonic sensor. A powder storage groove is opened inside the pipe plugging block. A powder inlet is opened outside the powder storage groove.

[0008] Furthermore, a left arc-shaped baffle is movably connected inside the powder storage groove. An arc-shaped gear bar is fixedly connected to the outside of the left arc-shaped baffle. A gear bearing is movably meshed with the outside of the arc-shaped gear bar. An inclined gear is fixedly connected to the outside of the gear bearing. A transmission bearing is fixedly connected to the outside of the inclined gear. The outside of the transmission bearing is movably connected to the internal machine box.

[0009] Furthermore, a right arc-shaped baffle is arranged outside the left arc-shaped baffle. The outside of the right arc-shaped baffle is movably connected to the internal machine box.

[0010] Furthermore, an electric telescopic device is fixedly connected to the outside of the pipeline plugging block. A telescopic column is movably sleeved inside the electric telescopic device. A powder pushing plate is fixedly connected to the outside of the telescopic column.

[0011] Furthermore, a bolt column is opened at the top of the main body shell. A bolt is movably sleeved on the temporal part of the bolt column. A first pressing plate is movably sleeved on the outside of the bolt. A sealing plug board is fixedly connected to the bottom of the first pressing plate. A sealing slot is arranged at the bottom of the sealing plug board.

[0012] Furthermore, a moisture-proof pad is movably sleeved on the outside of the bolt column. A pipeline hole is opened inside the moisture-proof pad. A cable pipeline is movably sleeved inside the pipeline hole.

[0013] Furthermore, an isolation baffle is fixedly connected inside the main body shell. An outer powder storage tank is opened on one side of the isolation baffle. An inner powder storage tank is opened on the other side of the isolation baffle. A powder extrusion channel is opened at the bottom of the inner powder storage tank.

[0014] The technical effects and advantages of the present invention:

[0015] 1. By using the flexibility of the flame-retardant rubber tube, the present invention squeezes and fixes the cable inserted into the cable pipeline. When the cable pipeline is not in use, the operator can rotate the octagonal nut, and the left outer turntable connected by the arc-shaped metal rod rotates. The left outer turntable rotates the closing plate and is connected to the right outer turntable. When the left outer turntable and the right outer turntable rotate, they drive the rotating bearing to rotate. Because the track of the rotating bearing is different from the tracks of the left outer turntable and the right outer turntable, the rotating closing plate is rotated to close and seal the cable pipeline, which is convenient for the operator to quickly insert the cable when using the reserved hole.

[0016] 2. The present invention drives the transmission bearing to rotate through the internal machine box. The transmission bearing drives the gear bearing by using an inclined gear. When the gear bearing rotates, it drives the left arc-shaped baffle to move by engaging with the arc-shaped gear bar, thereby blocking or opening the powder feed port. The pipe plugging block allows the flame retardant powder to flow from the powder feed port opened in the powder storage groove into the cable pipe. When harmful gases generated by combustion leak, the internal gaps of the pipe can be filled with the flame retardant powder to prevent the harmful gases from flowing.

One end of the arc-shaped metal rod 4 is fixedly connected to an octagonal nut 5. The other end of the arc-shaped metal rod 4 is fixedly connected to a left outer turntable 6. A rotary closing plate 7 is movably sleeved inside the left outer turntable 6. A rotating bearing 8 is movably sleeved outside the rotary closing plate 7. A right outer turntable 9 is movably sleeved outside the rotary closing plate 7. An electromagnetic ultrasonic sensor 10 is provided outside the right outer turntable 9. The flame retardant hose 3 uses its own flexibility to squeeze and fix the cable inserted into the cable duct 2. When the cable duct 2 is not in use, the operator can rotate the octagonal nut 5 and rotate the left outer turntable 6 connected by the arc-shaped metal rod 4. The left outer turntable 6 is connected to the right outer turntable 9 by the rotary closing plate 7. When the left outer turntable 6 and the right outer turntable 9 rotate, the rotating bearing 8 can be driven to rotate. Due to the different tracks of the rotating bearing 8 from those of the left outer turntable 6 and the right outer turntable 9, the cable duct 2 can be closed by rotation, facilitating the operator to quickly insert the cable when using the reserved hole and quickly plug the hole when not in use. And an electromagnetic ultrasonic sensor 10 is provided outside the right outer turntable 9 to detect whether there is harmful gas leakage.

[0027] In a preferred embodiment, a pipe plugging block 101 is fixedly connected to the outside of the electromagnetic ultrasonic sensor 10. A powder storage groove 102 is opened inside the pipe plugging block 101. A powder inlet 103 is opened outside the powder storage groove 102. The flame retardant powder flows from the powder inlet 103 opened in the powder storage groove 102 into the cable duct 2 through the pipe plugging block 101. When harmful gas leakage occurs during combustion, the internal gap of the cable duct 2 can be filled with the flame retardant powder to prevent the harmful gas from flowing.

[0028] In a preferred embodiment, a left arc-shaped baffle 104 is movably connected inside the powder storage groove 102. An arc-shaped gear bar 105 is fixedly connected to the outside of the left arc-shaped baffle 104. The outside of the arc-shaped gear bar 105 is movably engaged with a gear bearing 106. An inclined gear 107 is fixedly connected to the outside of the gear bearing 106. A transmission bearing 108 is fixedly connected to the outside of the inclined gear 107. The outside of the transmission bearing 108 is movably connected to an internal machine box 110. The internal machine box 110 drives the transmission bearing 108 to rotate.

When the gear bearing 106 rotates, it drives the left arc-shaped baffle 104 to move by engaging the arc-shaped gear bar 105, thereby blocking or opening the powder inlet 103.

[0029] In a preferred embodiment, a right arc-shaped baffle 109 is provided outside the left arc-shaped baffle 104. The outside of the right arc-shaped baffle 109 is movably connected to the internal machine box 110. The operation of the right arc-shaped baffle 109 is the same as that of the left arc-shaped baffle 104. The data detected by the electromagnetic ultrasonic sensor 10 is used to analyze whether there is harmful gas flow. When it exceeds a predetermined value, the motor will drive the transmission bearing 108 to rotate.

[0030] In a preferred embodiment, an electric telescopic device 201 is fixedly connected to the outside of the pipe plugging block 101. A telescopic column 202 is movably sleeved inside the electric telescopic device 201. A powder pushing plate 203 is fixedly connected to the outside of the telescopic column 202. The electric telescopic device 201 controls the rotation of the internal bolt, so that the telescopic column 202 is pushed by the thrust to push the powder pushing plate 203, enabling the existing flame retardant powder inside to be extruded into the cable duct 2 faster.

[0031] In a preferred embodiment, a bolt column 204 is opened at the top of the main body housing 1. A bolt 205 is movably sleeved on the temporal part of the bolt column 204. A first pressing plate 206 is movably sleeved on the outside of the bolt 205. A sealing plug plate 211 is fixedly connected to the bottom of the first pressing plate 206. A sealing slot 210 is provided at the bottom of the sealing plug plate 211. The bolt 205 sleeved on the bolt column 204 fixes the first pressing plate 206 and the second pressing plate 207 on the top of the moisture-proof plate at the top of the main body housing 1, and a sealing plug plate 211 is installed at the bottom of the first pressing plate 206 and the second pressing plate 207 to increase its sealing performance.

[0032] In a preferred embodiment, a moisture-proof pad 208 is movably sleeved outside the bolt column 204. A pipe hole 209 is formed inside the moisture-proof pad 208. A cable pipe 2 is movably sleeved inside the pipe hole 209. When the sealing plug 211 at the bottoms of the first pressing plate 206 and the second pressing plate 207 is nested inside the sealing slot 210, the moisture-proof pad 208 will also be squeezed inside the sealing slot 210, thereby increasing the moisture-proof effect and facilitating the operator to replace the new moisture-proof pad 208.

[0033] In a preferred embodiment, an isolation baffle 301 is fixedly connected inside the main body housing 1. An outer powder storage tank 302 is formed on one side of the isolation baffle 301, and an inner powder storage tank 303 is formed on the other side of the isolation baffle 301. A powder extrusion channel 304 is formed at the bottom of the inner powder storage tank 303. The inside of the main body housing 1 is divided into two outer powder storage tanks 302 and an inner powder storage tank 303 powder storage areas by the installed isolation baffle 301. A cable inlet fireproof plugging material (CN201910736707.1) is used inside the outer powder storage tank 302, and perlite flame retardant powder is stored inside the inner powder storage tank 303. The internal powder is extruded by the powder push plate 203 and quickly filled into the cable pipe 2.

[0034] The working principle of the present invention: A cable fireproof plugging device. The flame retardant hose 3 uses its own flexibility to squeeze and fix the cable inserted into the cable pipe 2. When the cable pipe 2 is not in use, the operator can rotate the octagonal nut 5 and rotate the left outer turntable 6 connected by the arc-shaped metal rod 4. The left outer turntable 6 is connected to the right outer turntable 9 by the rotating closing plate 7. When the left outer turntable 6 and the right outer turntable 9 rotate, the rotating bearing 8 can be driven to rotate. The rotating bearing 8 will close and seal the cable pipe 2 by rotation because its track is different from the tracks of the left outer turntable 6 and the right outer turntable 9, facilitating the operator to quickly insert the cable when using the reserved hole and quickly plug the hole when not in use. And an electromagnetic ultrasonic sensor 10 is provided outside the right outer turntable 9 to detect whether there is harmful gas leakage.

[0035] The pipeline plugging block 101 allows the flame retardant powder to flow from the powder feed port 103 opened in the powder storage groove 102 into the cable pipeline 2. When harmful gases generated by combustion leak, the internal gaps of the cable pipeline 2 can be filled with the flame retardant powder to prevent the harmful gases from flowing. The internal machine box 110 drives the transmission bearing 108 to rotate. The transmission bearing 108 drives the gear bearing 106 by means of the inclined gear 107. When the gear bearing 106 rotates, it drives the left arc-shaped baffle 104 to move by engaging with the arc-shaped gear bar 105, thereby plugging or opening the powder feed port 103. The operation of the right arc-shaped baffle 109 is the same as that of the left arc-shaped baffle 104. The data detected by the electromagnetic ultrasonic sensor 10 is analyzed to determine whether there is harmful gas flow. When the value exceeds the predetermined value, the motor drives the transmission bearing 108 to rotate. The electric telescopic device 201 controls the internal bolts to rotate, so that the telescopic column 202 is pushed by the thrust to drive the powder push plate 203 to squeeze the existing flame retardant powder inside into the cable pipeline 2 more quickly.

[0036] The bolts 205 sleeved on the bolt columns 204 fix the first pressing plate 206 and the second pressing plate 207 on the top of the moisture-proof board at the top of the main body housing 1. And a sealing plug plate 211 is installed at the bottoms of the first pressing plate 206 and the second pressing plate 207 to increase their sealing performance. When the sealing plug plate 211 at the bottoms of the first pressing plate 206 and the second pressing plate 207 is nested inside the sealing slot 210, the moisture-proof pad 208 is also squeezed inside the sealing slot 210, thereby increasing the moisture-proof effect and facilitating the operator to replace the new moisture-proof pad 208. The inside of the main body housing 1 is divided into two outer powder storage tanks 302 and an inner powder storage tank 303 for powder storage areas by the installed isolation baffle 301. A cable inlet fireproof plugging material (CN201910736707.1) is used inside the outer powder storage tank 302, and perlite flame retardant powder is stored inside the inner powder storage tank 303. The powder push plate 203 squeezes the internal powder to quickly fill it into the cable pipeline 2.
