Description

Technical Field

[0001] The utility model relates to the field of penetration devices, in particular to a novel detachable penetration device. Background Art

[0002] During the shipbuilding and construction process, our cables often need to pass through the walls in the separation areas between rooms and cabins. In order to meet the requirements of fire prevention, smoke prevention and dust prevention, our cables need to be blocked and filled in the penetration pieces during the passage (usually AB blocking material, which has the same properties as cement). This is also the requirement of classification societies and specifications.

[0003] During the blocking process of penetrations, after the cable is laid, the gaps between penetrations, the gaps between cables, and the parts where cables are not laid need to be blocked with AB plugging materials, so that the requirements of fire prevention, smoke prevention, and dust prevention can be met. However, the plugging materials are like cement, and they are very hard after drying. When we need to replace or add cables, there is no way to drill through them. This is a problem we often encounter. In addition, after the AB plugging materials are poured into the traditional penetrations, they are easy to flow out before they dry up, and there is a pungent smell, which is harmful to the health of personnel. For this reason, we propose a new type of detachable penetration device. Utility Model Content

[0004] The main purpose of the utility model is to provide a novel detachable penetration device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A novel detachable penetration device includes a wall. The detachable penetration device is composed of a first stuffing box, a second stuffing box, a steel plate and a welding bracket. A hole is opened on the wall, and cables pass through the wall. The first stuffing box and the second stuffing box are filled according to the number of cables. The first stuffing box and the second stuffing box are screwed onto the steel plate. The detachable penetration device is welded to the wall via a welding bracket.

[0007] Preferably, the top and side walls of the wall are both installed with a first stuffing box, a second stuffing box and a steel plate.

[0008] Preferably, threads matching the first stuffing box and the second stuffing box are punched on the steel plate, and the number of threads selected is consistent with the calculated number of threads of the first stuffing box and the second stuffing box.

[0009] Preferably, the first stuffing box and the second stuffing box are both screwed onto the steel plate.

[0010] Preferably, a hole the same size as the steel plate is opened on the path where the cable needs to pass, and the steel plate with the stuffing box locked is welded to the wall to seal the wall with the hole.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the new detachable penetration device can save construction time, reduce construction costs, and improve progress. It can solve the problem that after the traditional penetration parts are filled with AB plugging materials, they are easy to flow out before they are dried, and have a pungent odor, which is harmful to the health of personnel. After using this new penetration device, the construction is simple and convenient, and it is simple and quick to add cables later. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-5 As shown, a novel detachable penetration device includes a wall 4. The detachable penetration device is composed of a first stuffing box 1, a second stuffing box 2, a steel plate 3 and a welding bracket 5. A hole is opened on the wall 4, and the cables pass through the wall 4. The first stuffing box 1 and the second stuffing box 2 are filled according to the number of cables. The first stuffing box 1 and the second stuffing box 2 are screwed onto the steel plate 3. The detachable penetration device is welded to the wall 4 by the welding bracket 5.

[0020] The top and side walls of the wall 4 are both installed with a first stuffing box 1 , a second stuffing box 2 , and a steel plate 3 .

[0021] The steel plate 3 is punched with threads matching the first stuffing box 1 and the second stuffing box 2 , and the number of threads selected is consistent with the calculated number of the first stuffing box 1 and the second stuffing box 2 .

[0022] The first stuffing box 1 and the second stuffing box 2 are both screwed onto the steel plate 3 .

[0023] In which, a hole of the same size as the steel plate 3 is opened on the path where the cable needs to pass, and the steel plate 3 with the stuffing box locked is welded to the wall 4 to seal the wall 4 with the hole.

[0024] It should be noted that in conventional ship applications, we often use penetrations to lay cables in the middle, and use AB plugging materials to plug the gaps and spare parts of the cables. The plugging materials are very strong after drying. For this reason, we have designed a new type of detachable penetration device. On the cable path where the cables need to be laid, the number and type of cables are estimated, the outer diameter of the cables is confirmed, and then the matching stuffing box is selected according to the number of cables.

[0025] The stuffing box is a screw-tight type. 10% of the stuffing box needs to be reserved for later cable supplementation. The stuffing box can be locked. Select a steel plate 3, and punch threads matching the stuffing box on the steel plate 3. The number needs to be selected and consistent with the calculated amount of stuffing box, and then tighten the stuffing box on the steel plate 3. On the path where the cable needs to pass, open a hole of the same size as the steel plate 3, weld the steel plate with the locked stuffing box to the wall 4, block the hole in the wall 4, and then lay the cable and pass the cable through the stuffing box through the wall 4. Since the stuffing box is a spiral type, it can be easily disassembled. When additional cables are needed later, unscrew the spare stuffing box, and after the cable passes through the stuffing box, install the stuffing box and the cable together on the steel plate 3.

[0026] It is necessary to increase the stuffing box by 10% as spare. When laying the cable, pass the cable through the first stuffing box 1 and the second stuffing box 2, so that it is sealed. If additional cables are needed later, use the spare 10% stuffing box. After all the installation is completed, perform smoke test and other tests to confirm the tightness of the penetration.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
