Description

Technical Field

[0001] This application relates to the field of fire protection technology, and in particular to a fireproof putty anti-fall structure. Background Technology

[0002] Fireproof putty is a flexible flame-retardant material with excellent fire-retardant, smoke-blocking, oil-resistant, water-resistant, and corrosion-resistant properties. It is used to seal terminal boxes, mechanism boxes, outdoor cables entering the main control room, and cable trench exits of various voltage levels in substations to prevent fires from spreading to adjacent rooms through holes in wires and cables, thus reducing fire losses. It also prevents small animals from entering and causing secondary side grounding short circuits, which could lead to malfunctions in protection systems.

[0003] Existing cables are usually equipped with cable protection pipes. Currently, when fireproofing is used for sealing, personnel usually manually plug the holes at the ends of the cable protection pipes with fireproofing.

[0004] During use, fireproof putty is prone to softening at high temperatures, drying and weathering, and cable shaking, which reduces its adhesion and causes it to fall off, increasing maintenance costs. Utility Model Content

[0005] In view of this, this application provides a fireproof putty anti-fall structure to solve the problem that existing fireproof putty is prone to falling off due to reduced adhesion.

[0006] To achieve the above objectives, this application provides a fireproof putty anti-fall structure, which adopts the following technical solution: This application provides a fireproof putty anti-fall structure, including fixing components and a support net; The support net is connected to the fixing component. The support net is tubular and has a first opening and a second opening at both ends. The opening size of the first opening is larger than that of the second opening. The fixing component is located at the first opening and is used to fix it to the cable protection tube. The support net is configured to be fitted over the cable inside the cable protection tube to support the fireproof sealant between the cable protection tube and the cable.

[0007] Optionally, the support net includes a receiving section and a covering section connected to the receiving section. The receiving section is funnel-shaped to receive the fireproof putty, and the covering section is tubular with an opening size consistent with the second opening size. The covering section is used to be fitted onto the cable.

[0008] Optionally, the support mesh can be a metal mesh.

[0009] Optionally, the end of the net with the second opening abuts against the cable.

[0010] The optional fixing component includes at least two arc-shaped members, which are connected to the support net at the first opening, and the at least two arc-shaped members form a ring that matches the outer wall of the cable protection tube; The arc-shaped component is provided with at least one connecting part, and adjacent arc-shaped components are connected through the connecting part, so that the spacing between adjacent arc-shaped components is adjustable.

[0011] Optionally, adjacent arc-shaped members are provided with receiving grooves, and the connecting part includes at least two elastic members, the two ends of each elastic member being connected to the receiving grooves on the two adjacent arc-shaped members respectively.

[0012] Optionally, the connecting part further includes a telescopic sleeve, the two ends of which are connected to the receiving grooves on two adjacent arc-shaped members, and the elastic member passes through the telescopic sleeve.

[0013] The optional fixing assembly also includes at least two sets of connecting seats and at least two connecting bolts, wherein the connecting seats are mounted on the ends of the arc-shaped member, and the connecting seats on adjacent arc-shaped members are connected by the connecting bolts.

[0014] The optional fireproof putty anti-fall structure also includes at least two hooks, which are installed on the inner wall of the arc-shaped component; The hook is configured to engage with the end of the cable protection tube to mount the arc-shaped component onto the cable protection tube.

[0015] Optionally, a flexible layer is provided on the inner wall of the arc-shaped component.

[0016] Before filling with fireproof putty, a fireproof putty anti-fall-off structure needs to be installed. First, the support net is placed on the cable. The support net is then pulled up at the opening of the cable protection tube so that the second opening is located at the cable inside the cable protection tube. The support net is then fixed to the end of the cable protection tube from the first opening using the fixing components. The support net is then fixed between the cable protection tube and the cable. Subsequently, fireproof putty is filled into the support net until the end of the cable protection tube is sealed. The support net provides elastic support for the fireproof putty. Compared to directly filling the fireproof putty between the cable and the cable protection tube, the support net increases the bonding area of ​​the fireproof putty, reduces the probability of the fireproof putty falling off due to softening, weathering, cable shaking, etc., extends the service life of the fireproof putty, and reduces maintenance costs.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0023] Fireproof putty is a flexible flame-retardant material with excellent fire-retardant, smoke-blocking, oil-resistant, water-resistant, and corrosion-resistant properties. It is used to seal terminal boxes, mechanism boxes, outdoor cables entering the main control room, and cable trench exits of various voltage levels in substations to prevent fires from spreading to adjacent rooms through holes in wires and cables, thus reducing fire losses. It also prevents small animals from entering and causing secondary side grounding short circuits, which could lead to malfunctions in protection systems.

[0024] Existing cables are usually equipped with cable protection pipes. Currently, when fireproofing is used for sealing, personnel usually manually plug the holes at the ends of the cable protection pipes with fireproofing.

[0025] During use, fireproof putty is prone to softening at high temperatures, drying and weathering, and cable shaking, which reduces its adhesive strength and causes it to fall off, thus losing its protective function for the cables.

[0026] To address the aforementioned issues, this application provides a fireproof putty anti-fall structure to solve the problem that existing fireproof putty is prone to falling off due to reduced adhesion.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 4 As shown in the embodiment of this application, a fireproof mud anti-fall structure is provided, including a fixing component 100 and a support net 200.

[0029] The support net 200 is connected to the fixing component 100. The support net 200 is tubular. The two ends of the support net 200 are respectively provided with a first opening 200a and a second opening 200b. The opening size of the first opening 200a is larger than the opening size of the second opening 200b. The fixing component 100 is located at the first opening 200a and is used to fix it to the cable protection pipe 2000.

[0030] The support net 200 is configured to be fitted onto the cable 1000 inside the cable protection tube 2000 to support the fireproof sealant between the cable protection tube 2000 and the cable 1000.

[0031] Before filling with fireproof putty, a fireproof putty anti-fall structure needs to be installed. First, the support net 200 is placed on the cable 1000. The support net 200 is then pulled up at the opening of the cable protection tube 2000, so that the second opening 200b is located at the cable 1000 inside the cable protection tube 2000. The support net 200 is then fixed to the port of the cable protection tube 2000 through the fixing component 100 from the first opening 200a. The support net 200 is thus fixed to the cable protection tube 2000 and the cable 1000. Then, fireproof putty is filled at the support net 200 until the fireproof putty seals the port of the cable protection tube 2000. The support net 200 provides elastic support for the fireproof putty. Compared with directly filling the fireproof putty between the cable 1000 and the cable protection tube 2000, the support net 200 increases the bonding area of ​​the fireproof putty, reduces the probability of the fireproof putty falling off due to softening, weathering, or the shaking of the cable 1000, extends the service life of the fireproof putty, and reduces maintenance costs.

[0032] Furthermore, refer to Figure 1As shown, the support net 200 includes a receiving section 210 and a covering section 220 connected to the receiving section 210. The receiving section 210 is funnel-shaped and is used to receive fireproof putty. The covering section 220 is tubular and the opening size of the covering section 220 is the same as the size of the second opening 200b. The covering section 220 is used to be sleeved on the cable 1000.

[0033] The receiving section 210 is trumpet-shaped, and its opening size gradually decreases from the first opening 200a to the second opening 200b. The open design of the receiving section 210 improves the convenience of placing fireproof putty into the support net 200 from the first opening 200a, increases the bonding area between the fireproof putty and the support net 200, and reduces the probability of the fireproof putty falling off. At the same time, the receiving section 210 restricts the shape of the fireproof putty to be filled to a cone, which makes the bonding stability of the fireproof putty higher.

[0034] At the same time, the size of the covering section 220 is consistent with the opening size of the second opening 200b. Thus, when the covering section 220 is fitted onto the cable 1000 and the support net 200 is lifted, due to the mesh structure of the support net 200, the covering section 220 of the support net 200 will automatically shrink and adhere to the outer wall of the cable 1000. While the fixing component 100 fixes the first opening 200a of the support net 200 onto the cable protection tube 2000, the covering section 220 connects the second opening 200b of the support net 200 to the cable 1000, thereby improving the installation stability of the support net 200.

[0035] Optionally, the support net 200 can be made of metal mesh. Metal mesh has advantages such as corrosion resistance, high strength, and strong adaptability. At the same time, the metal material improves the reusability of the support net 200, making it energy-saving and environmentally friendly.

[0036] Preferably, the support net 200 is a metal braided mesh, which has a certain deformation capacity and is suitable for cables 1000 and cable protection tubes 2000 of different diameters.

[0037] In some examples, the end of the net 200 with a second opening 200b abuts against the cable 1000.

[0038] When the support net 200 is installed on the cable 1000, the support net 200 adheres to the outer wall of the cable 1000 through the second opening 200b, which reduces the probability of some of the fireproof putty falling off from the connection between the covering section 220 and the cable 1000 during filling, and improves the filling safety of the fireproof putty.

[0039] Furthermore, the fixing component 100 includes at least two arcuate members 110, which are connected to the support net 200 at the first opening 200a, and the at least two arcuate members 110 form a ring that matches the outer wall of the cable protection tube 2000.

[0040] The arc-shaped component 110 is provided with at least one connecting part 300, and adjacent arc-shaped components 110 are connected through the connecting part 300, so that the distance between adjacent arc-shaped components 110 is adjustable.

[0041] The arc-shaped component 110 is installed at the opening of the cable protection tube 2000 to fix the end of the support net 200 with the first opening 200a. The connecting part 300 ensures the connection and forming between the arc-shaped components 110. At the same time, under the elastic action of the support net 200, there is a certain tension force on the multiple arc-shaped components 110, so that the multiple arc-shaped components 110 are tightened on the outer wall of the cable protection tube 2000. The spacing between the arc-shaped components 110 is adjustable, so that the size and inner diameter of the ring formed by the arc-shaped components 110 are adjustable, which improves the adaptability of the fixing component 100 to cable protection tubes 2000 of different diameters.

[0042] Furthermore, refer to Figure 4 As shown, adjacent arc-shaped members 110 are provided with receiving grooves 111 opposite each other, and the connecting part 300 includes at least two elastic members 310, the two ends of each elastic member 310 being connected to the receiving grooves 111 on the two adjacent arc-shaped members 110.

[0043] By setting elastic elements 310 on two adjacent arc-shaped parts 110, the elastic tension between adjacent arc-shaped parts 110 is increased, thereby improving the installation tightness of the arc-shaped parts 110 and ensuring the stable installation of the arc-shaped parts 110; the setting of the receiving groove 111 provides receiving space for the elastic element 310. When two adjacent arc-shaped parts 110 abut against each other, the elastic element 310 is simultaneously located in the two opposite receiving grooves 111, improving the space utilization rate of the arc-shaped parts 110.

[0044] In addition, the connecting part 300 also includes a telescopic sleeve 320, the two ends of which are respectively connected to the receiving grooves 111 on the two adjacent arc-shaped members 110, and the elastic member 310 passes through the telescopic sleeve 320.

[0045] By providing a telescopic sleeve 320 outside the elastic member 310, when two adjacent arc-shaped members 110 are not in contact, the telescopic sleeve 320 protects the receiving groove 111 and the elastic member 310, preventing airborne debris from entering the receiving groove 111 and affecting the performance and service life of the elastic member 310.

[0046] In some examples, the telescopic sleeve 320 is an elastic cylinder that elastically deforms as the distance between two adjacent arcuate members 110 changes, protecting the receiving groove 111 and the elastic member 310.

[0047] In some other examples, not shown in the figure, the telescopic sleeve 320 includes a first cylinder and a second cylinder. The first cylinder is sleeved outside the second cylinder and the two are slidably disposed. The first cylinder and the second cylinder are respectively fixed in two opposite receiving grooves 111. The elastic element 310 is located inside the second cylinder. When the distance between two adjacent arc-shaped elements 110 changes, the first cylinder and the second cylinder slide relative to each other to increase or decrease the overall length of the telescopic sleeve 320.

[0048] In addition, the fixing assembly 100 also includes at least two sets of connecting seats 120 and at least two connecting bolts 130. The connecting seats 120 are installed at the ends of the arc-shaped members 110, and the connecting seats 120 on adjacent arc-shaped members 110 are connected by connecting bolts 130.

[0049] After the arc-shaped component 110 is fitted onto the cable protection tube 2000, the two adjacent connecting seats 120 are fixed by the connecting bolts 130, thus fixing the two adjacent arc-shaped components 110, preventing the arc-shaped components 110 from moving or misaligning during use, and improving the installation stability of the fixing component 100.

[0050] Furthermore, the fireproof putty anti-fall structure also includes at least two hooks 140, which are mounted on the inner wall of the arc-shaped member 110. The hooks 140 are configured to engage with the end of the cable protection tube 2000 to mount the arc-shaped member 110 onto the cable protection tube 2000.

[0051] By setting a hook 140 on the arc-shaped component 110, before the connecting bolt 130 connects to the connecting seat 120 on the adjacent arc-shaped component 110, the arc-shaped component 110 is first pre-connected to the cable protection pipe 2000 by the hook 140, thereby achieving the pre-positioning of the arc-shaped component 110 and improving the installation efficiency of the arc-shaped component 110.

[0052] In some embodiments, a flexible layer is provided on the inner wall of the arc-shaped member 110. When the arc-shaped member 110 is installed on the cable protection tube 2000, the inner wall of the arc-shaped member 110 abuts against the outer wall of the cable protection tube 2000. By providing the flexible layer, the friction between the arc-shaped member 110 and the cable protection tube 2000 is reduced, thereby extending the service life of both the arc-shaped member 110 and the cable protection tube 2000. In some examples, the flexible layer may be a sponge cloth.

[0053] The fireproof putty anti-fall structure provided in this application needs to be installed between the cable 1000 and the cable protection pipe 2000 before filling the fireproof putty. First, the support net 200 is placed on the cable 1000. Then, the support net 200 is pulled up at the opening of the cable protection pipe 2000, causing the covering section 220 to automatically retract and adhere to the outer wall of the cable 1000. Multiple arc-shaped pieces 110 are then hung at the opening of the cable protection pipe 2000 using hooks 140. The elastic tension of the elastic element 310 pulls each pair of arc-shaped pieces 110 together, ensuring that all arc-shaped pieces 110 are tightly secured to the outer wall of the cable protection pipe 2000. Subsequently, connecting bolts 130 are used to connect each group of two adjacent connecting seats 120, achieving connection between adjacent arc-shaped pieces 110. The position of the arc-shaped pieces 110 is fixed. Simultaneously, through… The fixing component 100 fixes the support net 200 to the port of the cable protection tube 2000 through the first opening 200a. The covering section 220 connects the second opening 200b of the support net 200 to the cable 1000. The receiving section 210 is fixed in an open state between the cable protection tube 2000 and the cable 1000. Then, fireproof putty is filled into the receiving section 210 until the fireproof putty seals the port of the cable protection tube 2000. The support net 200 provides elastic support for the fireproof putty. Compared with directly filling the fireproof putty between the cable 1000 and the cable protection tube 2000, the support net 200 increases the bonding area of ​​the fireproof putty, reduces the probability of the fireproof putty falling off due to softening, weathering, or cable 1000 shaking, extends the service life of the fireproof putty, and reduces maintenance costs.
