Description

Technical Field

[0001] This invention relates to the field of fireproof sealing technology for cable laying, and more specifically to a fireproof sealing device for cable laying. Background Technology

[0002] With the widespread application of power, communication, and network systems, the laying of cables in buildings is becoming increasingly complex. Cable fires can have serious consequences, thus fireproof sealing technology has emerged. Early methods used materials such as cement and gypsum to seal cable holes, but these materials are prone to cracking at high temperatures, resulting in limited fireproofing effectiveness. Modern fireproof sealing devices use intumescent fire-retardant materials, fire-retardant coatings, and specialized sealing modules, which can expand at high temperatures to form a heat insulation layer, effectively preventing the spread of fire and possessing good sealing and durability. However, existing technologies still have shortcomings, as detailed below:

[0003] 1. Existing fire-stopping devices lack adjustable fixing mechanisms, making them unable to flexibly adapt to cable layouts of different sizes or quantities. When the number or size of cables changes, the size of the sealing device cannot be adjusted as needed, which may result in poor sealing performance or reduced fire resistance. The lack of adjustable fixing mechanisms also makes the installation process more cumbersome, especially when the cable layout is irregular, as the fixing device may not be able to accurately fix the cables, which may result in the device not being able to be installed securely.

[0004] Second, fire-stopping materials such as intumescent graphite and refractory paste may expand at uneven rates at high temperatures, resulting in incomplete sealing. Flames, smoke, or harmful gases may spread through some gaps that are not completely sealed. Different fire-stopping materials have different fire resistance limits, and some materials may fail prematurely at high temperatures, thus failing to achieve the expected fire-stopping effect.

[0005] Therefore, the present invention urgently needs a fireproof sealing device for cable laying. Summary of the Invention

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The present invention provides a fireproof sealing device for cable laying, including a support mechanism 1, a fireproof mechanism 2, a clamping mechanism 3 and a fixing mechanism 4. The inner side of the support mechanism 1 is connected to the side of the fireproof mechanism 2, and a cable 5 is fixedly connected to the inner side of the fireproof mechanism 2. The inner side of the support mechanism 1 is fixedly connected to the side of the fixing mechanism 4, the inner side of the fixing mechanism 4 is connected to the side of the clamping mechanism 3, and the inner side of the clamping mechanism 3 is fixedly connected to the side of the cable 5.

[0032] The fireproof mechanism 2 includes a first fixed frame 21 and a second fixed frame 213. A slider 211 is fixedly connected to the side of the first fixed frame 21. The side of the slider 211 is connected to the inner side of the support mechanism 1. A magnetic block 212 is fixedly connected to the side of the first fixed frame 21. The side of the magnetic block 212 is fixedly connected to the side of the second fixed frame 213. The side of the second fixed frame 213 is connected to the inner side of the support mechanism 1.

[0033] The clamping mechanism 3 includes a first guide plate 31 and a rotating plate 322. The bottom end of the first guide plate 31 is connected to the side of the rotating plate 322. A T-shaped sliding groove 311 is provided at the top end of the first guide plate 31. A first I-shaped plate 33 is connected to the inner side of the T-shaped sliding groove 311. A first connecting groove is provided at the bottom end of the first guide plate 31. The inner side of the first connecting groove is connected to the side of the connecting rod 332. The side of the first guide plate 31 is fixedly connected to the inner side of the fixing mechanism 4.

[0034] The support mechanism 1 includes an outer protective frame 101, with a movable annular groove 102 on the inner side of the outer protective frame 101. The inner side of the movable annular groove 102 is connected to the side of the second fixed frame 213. A positioning groove 103 is provided at the top of the movable annular groove 102. The inner side of the positioning groove 103 is connected to the side of the slider 211. A placement groove 104 is provided on the side of the outer protective frame 101. The inner side of the placement groove 104 is fixedly connected to the bottom of the clamping mechanism 3. A movable groove 105 is provided on the side of the outer protective frame 101. The inner side of the movable groove 105 is connected to the side of the clamping mechanism 3.

[0035] The first fixed frame 21 is fixedly connected to the inner side of the first fireproof layer 22, the top of the first fireproof layer 22 is connected to the second fireproof layer 221, the side of the second fireproof layer 221 is fixedly connected to the inner side of the second fixed frame 213, the side of the first fireproof layer 22 is fixedly connected to the elastic ring 222, the side of the elastic ring 222 is fixedly connected to the side of the cable 5, and the side of the first fixed frame 21 is connected to the inner side of the movable ring groove 102.

[0036] The slider 211, fixed to the sides of the first fixed frame 21 and the second fixed frame 213, slides inside the positioning groove 103 on the side of the outer protective frame 101. This causes the first fireproof layer 22 and the second fireproof layer 221 to move to the inside of the moving annular groove 102, providing flame protection to both ends of the outer protective frame 101. During its movement inside the moving annular groove 102, the slider 211 is less likely to pull the first fixed frame 21 out of the groove, thus serving a limiting function. The first fireproof layer 22 and the second fireproof layer 221 divide the incoming flames into multiple smaller flames, thereby reducing the concentrated temperature of the flames and protecting the electrical components at the other end. Cable 5 is no longer affected by high temperature. The first fireproof layer 22 and the second fireproof layer 221 are both made of high temperature resistant and non-flammable materials. The cable 5 is fixed to the inner side of the outer protective frame 101 by the elastic ring 222. Since the elastic ring 222 is elastic, multiple cables 5 can be fixed together. Magnetic blocks 212 are fixed on the sides of the first fixing frame 21 and the second fixing frame 213. The frames on both sides of the elastic ring 222 are fixed by the mutual approach of the two. The sides of the first fireproof layer 22 and the second fireproof layer 221 are fixed to the sides of the elastic ring 222, so they can be slightly changed according to the size of the first fireproof layer 22.

[0037] Reference Figures 4 to 8 The clamping mechanism 3 includes a second guide plate 313, a first auxiliary groove 314 is provided on the side of the second guide plate 313, the top of the second guide plate 313 is connected to the bottom of the rotating plate 322, a second connecting groove is provided on the top of the second guide plate 313, and the side of the second guide plate 313 is fixedly connected to the inner side of the fixing mechanism 4.

[0038] The rotating disk 322 has a rotating tooth 32 fixedly connected to its side. The rotating disk 322 has a telescopic groove 321 on its side. The inner side of the telescopic groove 321 is connected to the side of the clamping mechanism 3. The top of the rotating disk 322 has a second auxiliary groove 324. The inner side of the second auxiliary groove 324 is connected to a sliding ball 323. The side of the sliding ball 323 is connected to the inner side of the first auxiliary groove 314. The side of the rotating disk 322 is connected to the inner side of the fixing mechanism 4.

[0039] The top end of the connecting rod 332 is fixedly connected to the bottom end of the first I-shaped plate 33, the side of the connecting rod 332 is connected to the inner side of the telescopic groove 321, the bottom end of the connecting rod 332 is fixedly connected to the second I-shaped plate 331, the side of the second I-shaped plate 331 is connected to the side of the second guide plate 313, the bottom end of the second I-shaped plate 331 is fixedly connected to the pressure plate 334, the side of the pressure plate 334 is fixedly connected to the cleaning ball 335, the side of the cleaning ball 335 is connected to the side of the cable 5, the top end of the first I-shaped plate 33 is fixedly connected to the expansion plate 333, and the side of the expansion plate 333 is connected to the side of the cable 5.

[0040] The clamping mechanism 3 includes a drive gear 34, the side of the drive gear 34 meshes with the side of the rotating gear 32, the bottom end of the drive gear 34 is fixedly connected to a rotating shaft 342, the bottom end of the rotating shaft 342 is fixedly connected to a rotating motor 341, the side of the rotating motor 341 is fixedly connected to the inner side of the mounting groove 104, and the side of the drive gear 34 is connected to the inner side of the mounting groove 104.

[0041] The fixing mechanism 4 includes a fixing ring 401, a through groove 402 on the side of the fixing ring 401, the inner side of the through groove 402 being connected to the side of the first I-shaped plate 33, an annular groove 403 on the side of the fixing ring 401, the inner side of the annular groove 403 being fixedly connected to the side of the first guide plate 31, and a rotating groove 404 on the side of the fixing ring 401, the side of the rotating groove 404 being connected to the side of the rotating tooth 32.

[0042] The inner side of the expansion plate 333, which is fixed at the top of the first I-shaped plate 33, contains an expandable material. When the inner side of the expansion plate 333 contacts the side of the cable 5, it will expand and fill the gap between the cables 5. After the impurities on the surface of the cable 5 are brushed off by the cleaning ball 335, it does not affect the subsequent filling effect of the expansion plate 333. Moreover, the positions of the first I-shaped plate 33 and the second I-shaped plate 331 at both ends of the connecting rod 332 are flush. The cleaning ball 335 on the inner side of the pressure plate 334 has a certain length, which can clean the cable 5 without affecting the fixing effect of the expansion plate 333. Therefore, when the connecting rod 332 drives the first I-shaped plate 33 and the second I-shaped plate 331 to move synchronously, the cleaning and clamping do not affect each other.

[0043] When the cable 5 needs to be moved, the size of the expansion plate 333 is slightly larger than the size of the cable 5, and the cleaning ball 335 inside the pressure plate 334 also has cleaning pressure. When the cable 5 needs to be fixed, the moving connecting rod 332 is moved by the meshing action between the drive gear 34 and the rotating gear 32, so that the expansion plate 333 expands when it comes into contact with the cable 5, filling the gaps on its side. If the cable 5 needs to be replaced, the expansion plate 333 can be replaced with a new one for the next use.

[0044] The working principle of this invention is as follows: the cable 5 is inserted into the inner side of the fireproof mechanism 2 and the clamping mechanism 3, and the inner side of the wall is fixed by the outer side of the outer protective frame 101, which also protects the cable 5. The fireproof mechanism 2 is fixed to its inner side by the movable annular groove 102 on the inner side of the outer protective frame 101. Similarly, the inner side of the outer protective frame 101 fixes the side of the fixing mechanism 4, making its clamping effect on the cable 5 more stable.

[0045] The cable 5 passes through the inner side of the elastic ring 222. The elastic ring 222 has a certain degree of elasticity, allowing it to adhere tightly to the side of the cable 5. The second fireproof layer 221 and the first fireproof layer 22 on the side of the elastic ring 222 change with the elastic ring 222, allowing for a better fit to the side of the cable 5. When flames appear at the end of the outer protective frame 101, they are blocked by the first fireproof layer 22 and the second fireproof layer 221, thus extinguishing the flames approaching the side of the second fireproof layer 221. This improves the effectiveness of the fire-resistant mechanism 2. The effect can be achieved by increasing the number of the first fireproof layer 22 and the second fireproof layer 221 to protect the inner side of the outer protective frame 101. The first fireproof layer 22 is fixed on the side of the elastic ring 222 by the first fixing frame 21 and the second fixing frame 213. The first fixing frame 21 is placed into the inner side of the moving ring groove 102 by sliding the slider 211 against the side of the positioning groove 103. When the sides of the first fixing frame 21 and the second fixing frame 213 are connected, they are fixed by the magnetic block 212 to better protect the cable 5.

[0046] When the cable 5 enters the inner side of the outer protective frame 101, it first passes through the inner side of the second guide plate 313. The pressure plate 334 and the cleaning ball 335 are placed inside the second guide plate 313. Therefore, the cable 5 is cleaned first when it is installed and fixed, and then it is fixed in a suitable position. The rotating shaft 342 is rotated by starting the rotating motor 341, which in turn drives the drive gear 34 to rotate. The side of the drive gear 34 meshes with the side of the rotating gear 32, which drives the rotating plate 322 to rotate. The connecting rod 332 placed inside the telescopic groove 321 slides inside the rotating plate 322, which drives the pressure plate 334 at the top of the second I-shaped plate 331 to move to the side of the cable 5 to clean the cable 5.

[0047] At the same time, the first I-shaped plate 33 at the top of the connecting rod 332 also moves to the side of the cable 5 as the rotating disk 322 rotates. When the cable 5 has reached the required length and is no longer moving, the expansion plate 333 at the top of the first I-shaped plate 33 begins to release expansion agent. Under the pressure of the first I-shaped plate 33 and the cable 5, the expansion agent inside the expansion plate 333 fills the gap on the surface of the cable 5, ensuring the clamping effect of the first I-shaped plate 33 on the cable 5. Moreover, after the gap between the first I-shaped plate 33 and the cable 5 is filled, the risk of the cable 5 being corroded is reduced.

[0048] During the rotation of the rotating disk 322, the connecting rod 332 slides inside the telescopic groove 321 and changes the distance between the multiple expansion plates 333 and the distance between the multiple pressure plates 334. During the sliding of the connecting rod 332 inside the telescopic groove 321, the first I-shaped plate 33 and the second I-shaped plate 331 fixed at both ends of the connecting rod 332 also slide inside the T-shaped sliding groove 311, thereby driving the expansion plates 333 and the pressure plates 334. The rotating disk 322 is provided with a second auxiliary groove 324 on both sides, and the bottom end of the first guide disk 31 is also provided with a first auxiliary groove 314. A sliding ball 323 is placed between the two to reduce the friction between the first guide disk 31 and the rotating disk 322. Through the action of the sliding ball 323, the frictional sliding between the rotating disk 322 and the first guide disk 31 is changed to rolling, so as not to affect the relative movement between the second guide disk 313 and the rotating disk 322. Moreover, the sliding of the first I-shaped plate 33 on the side of the first guide disk 31 is directionally slid through the connection of the T-shaped sliding groove 311.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
