the splicing blocks 1 are used for splicing to form a cylindrical structure with a target length, a circumferentially closed cable through hole 3 is formed in the inner side of the cylindrical structure, and the cable through hole 3 extends along the axial direction of the cylindrical structure; it can be understood that the purpose of circumferential closing of the cable perforation is to completely wrap the outer surface of the cable to be fixed, and the gap at the joint of the adjacent rubber plates can be squeezed to form a closed space.

The splice 1 comprises a body; the main body comprises a sealing component 11 with a sector-shaped cross section, and the cable through hole 3 is positioned on the inner side of the sealing component 11;

the sealing assembly 11 comprises a plurality of flexible sealing plates which are arranged in a stacked mode and have arc-shaped cross sections, and the number of the flexible sealing plates is adjusted to enable the cable through hole 3 to be matched with the outer diameter of a cable to be fixed.

The protection device that this application embodiment provided adopts the mode of components of a whole that can function independently concatenation to form the protection in the outside corresponding part of treating fixed cable, guarantees crossing similar concrete wall and is, can form the protection to the cable, can also guarantee simultaneously that crossing of cable contact site is wrapped up in the inside of device completely, reaches good sealed effect.

It can be understood that the device provided by the embodiment of the application is different from the traditional protection device in actual use. When the traditional protection device is used, the wall body needs to be poured at first, and after the wall body is punched, the protection device is placed in a wall hole and then is threaded. The device provided by the embodiment of the application needs to be firstly connected with the cable to be fixed before the wall body is poured.

When the flexible sealing plate splicing device is used, the wall penetrating position of a cable is firstly measured, the number of the required flexible sealing plates is determined according to the outer diameter of the cable, and the number of the flexible sealing plates protected by each splicing block is adjusted to be the same, so that the inner diameter of a cable through hole formed after splicing is not larger than the outer diameter of the cable. Then, the splicing blocks are sequentially arranged on the outer side of the cable through-wall part, the splicing blocks are fixed along the circumferential direction of the splicing blocks through external fastening components, and the splicing blocks can be fixed by adopting metal binding bands, pipe clamp fastening components or iron wires and the like. After being fixed, each splicing block can ensure that the contact parts of the sealing components of the adjacent splicing blocks are closely contacted, so that the cable is perforated to form a closed structure, and the cable through-wall part is completely wrapped. After each splicing block is fixed, the device and the cable can be fixed together with a steel reinforcement cage for wall pouring, and the device is prevented from shifting in the wall pouring process. The device can carry out the wall body and pour after being connected with the steel reinforcement cage. And the cable wall-penetrating construction is also completed while the wall body pouring is completed.

Through the mode that sets up multilayer flexible sealing plate, can guarantee that the device can use by the cable of multiple different diameters altogether, improved the range of application of device.

In order to further improve the service life of the device and simultaneously prevent the sealing assembly from being damaged when the wall body is poured, the embodiment of the application may provide that the main body includes a hard shell 12 with a sector-shaped cross section, and the sealing assembly 11 is located inside the hard shell 12. The shell made of hard materials can well protect the sealing assembly inside the shell.

Because each splicing block of the sealing assembly provided by the embodiment of the application can be subjected to pressure along the radial direction from outside to inside in the splicing process, local wrinkle deformation can occur on the sealing assembly which is difficult to keep perfect sector structures under the action of the pressure, especially once the sealing assemblies at two ends of the main body generate larger deformation, gaps can be generated on local contact positions of the sealing assembly and a cable, in order to ensure that the parts of the sealing assembly at the two ends keep arc structures as much as possible and reduce the deformation such as wrinkles and the like, the splicing block also can provide flange assemblies at two ends of the main body, each flange assembly comprises a flange plate 13 with an arc structure and a plastic plate 14, the flange plate 13 is fixedly connected with the hard shell 12, and the plastic plates 14 are detachably connected with the flange plates 13 through a plurality of bolts; the end of the sealing assembly 11 extends to the outside of the hard casing 12, so that the inner side surface of the shaping plate 14 is lower than the outer side surface of the sealing assembly 11 after the shaping plate 14 is connected with the flange plate 13.

The main part is set up behind the outside of cable, links to each other the shaping plate with the flange board, because the shaping plate adopts stereoplasm materials such as metal material to make, and its inboard has the arc structure simultaneously, consequently can provide even radial pressure to the seal assembly rather than the contact for take place the position of deformation such as fold and resume deformation under this pressure. It can be understood that the shaping plate provided by the embodiment of the application adopts a mode that two arc-shaped plate bodies are spliced to form a circular structure, and in practical application, the plate body with an integral circular ring-shaped structure can be used as the shaping plate. When the flange plate is applied specifically, only through holes corresponding to the flange plate need to be formed in the annular plate body, and the annular plate body is fastened by bolts. The annular shaping plate can also ensure that the sealing assembly is close to a circle as much as possible in an inner side circular structure of the sealing assembly, and reduce the occurrence of deformation such as folds and the like, thereby achieving the effect of improving the sealing effect.

Since the outer surface of the housing provided by the embodiment of the present application generally has a smooth structure in practical applications, in order to prevent the device from rotating circumferentially after being disposed in a wall, the embodiment of the present application may further provide that a plurality of limiting rods 15 are disposed on the flange plate 13, and the ends of the limiting rods 15, which are far away from the flange plate 13, extend to the outside of the outer surface of the hard housing 12. Through the arrangement of the limiting rod, the device can be guaranteed not to rotate in the circumferential direction after being poured in a wall body, and the stability of the device after being installed is improved.

In order to ensure that all the splicing blocks are accurately positioned after being spliced and no transverse and longitudinal dislocation occurs, the embodiment of the application can provide that the surfaces of the flange plates which are spliced with each other are provided with a limiting block 16 and a limiting groove 17 or one of the limiting block 16 and the limiting groove 17;

after two adjacent splicing blocks are spliced, a limiting block 16 on one flange plate is inserted into a limiting groove 17 on the adjacent flange plate. When splicing, the accurate connecting position can be ensured through the limiting blocks and the limiting grooves.

In one embodiment, only the limiting block 16 is arranged on one flange plate, and only the limiting groove 17 is arranged on one flange plate. In one embodiment, a flange plate is provided with both the limiting blocks 16 and the limiting grooves 17, as shown in fig. 2. The latter is advantageous to simplify the part variety.

In order to further improve the accuracy of the position after connection, the embodiment of the present application may further provide that the cross-sectional shape and size of the limiting block 16 is matched with the cross-sectional shape and size of the limiting groove 17, and the two are in male-female fit. The purpose of further improving the connection positioning precision is achieved through the adaptive insertion mode.

It will be appreciated that embodiments of the present application provide that after the seal assembly is initially installed in a wall, the flexible sealing sheet is in a compressed state and provides a radially outward force to the housing which causes the housing to engage the aperture formed in the wall. However, as time goes on, the stress provided by the flexible sealing plate gradually disappears, and the shells may be inwardly closed and finally separated from the wall, so that a gap is formed between the shells and the wall, and the sealing effect of the wall is affected. In addition, the flexible sealing plate is subjected to all the pressure, so that the aging deformation speed is increased, and the shaft sealing performance is reduced. In order to solve the problem, in the embodiment of the present application, a spring 18 and a movable block 19 may be disposed in the limiting groove 17, one end of the spring 18 is connected to the bottom surface of the limiting groove 17, and the other end of the spring 18 is connected to the movable block 19; after two adjacent splicing blocks 1 are spliced, the limiting block 16 is abutted to the movable block 19, and the spring 18 is in a compressed state. Further, in order to improve the elastic performance, the spring 18 includes a plurality of strips arranged in parallel. The spring provides an acting force opposite to the pressure born by the flexible sealing plate, so that the stress of the flexible sealing plate can be greatly reduced, and the flexible sealing plate is not easy to deform. In addition, because the aging speed of the spring is lower than that of rubber, the flexible sealing plate can provide longer supporting force for the shell to ensure that the shell cannot be separated from the wall.

In order to further improve the sealing performance of the cable through hole end, as shown in fig. 5, the present embodiment may further provide that the cable through hole further includes auxiliary sealing assemblies 2 disposed at two ends inside the cable through hole 3; the auxiliary sealing component 2 is flatly distributed on the inner side of the cable perforation 3 in an unstressed state; after the cable 4 to be fixed is arranged in the cable through hole 3, the auxiliary sealing component 2 is distributed in the circumferential direction of the cable 4 to be fixed under the action of external force applied by the cable 4 to be fixed. As shown in fig. 6. The auxiliary sealing assembly has a smaller width relative to the sealing assembly, is arranged at a position close to the end face of the cable through hole, and can be dispersed outwards around the cable under the action of the cable after the cable is installed in the cable through hole, so that a gap between the cable and the innermost flexible sealing plate is closed.

Specifically, the auxiliary sealing assembly 2 comprises a flexible sealing sheet connected with the inner side surface of the innermost flexible sealing plate of the sealing assembly; the surface of the flexible sealing sheet is parallel to the end face of the cable perforation. The number of the rubber sheets can be the same as that of the splicing blocks, and can also be different from that of the splicing blocks. The material is soft rubber material, which is beneficial to deformation.

In practical applications, the flexible material may be selected in various ways. For example, in one implementation, the flexible sealing plate and the flexible sealing sheet may be made of rubber.

In a word, the cable that this application provided passes through contact site protector, simple structure is reasonable, installation convenient to use. The split combination mode is favorable for transportation, and meanwhile, the requirement on the technical level of workers can be reduced when the cable is connected. The number of the flexible sealing plates which are arranged in a stacked mode can be increased or decreased according to the diameter of the cable, and therefore the cable perforation which is suitable for the cable is assembled. So that the device has wider application range. Meanwhile, the device can obtain a good sealing effect. Is worthy of large-area popularization and application.
