The traditional through-hull device is made of steel and is usually connected to the hull by welding and flange connection methods, which will increase the weight of the hull and is very inconvenient for the staff to operate;
[0004] With the development of yacht lightweighting, the pipeline system is changed to PVC plastic pipes, but it is difficult to directly communicate with the aluminum alloy bulkhead or deck, and a certain through-hull device needs to be used as an auxiliary to meet the connection conditions. In the prior art, for pipe bodies with different diameters, through-hull devices with different inner diameters need to be matched, and the through-hull devices with different inner diameters also need to be matched with holes with different diameters on the bulkhead or deck for installation. Therefore, multiple hole punching and multiple welding are required to complete the installation, with poor adaptability and high usage costs. Summary of the Utility Model

[0042] Referring to Figure 1 and Figure 2 , Figure 1 is a three-dimensional schematic diagram of a metal sleeve in a pipeline fireproof penetration device of the present application, Figure 2 is a three-dimensional schematic diagram of a pipe locking mechanism in a pipeline fireproof penetration device of the present application. As shown in Figure 1 and Figure 2 shown, a pipeline fireproof penetration device includes a variable-diameter fixing mechanism 20 arranged inside a metal sleeve 10 and a pipe locking mechanism 50 sleeved outside a pipe body 40;
[0043] Reference Figure 3 、 Figure 4 and Figure 5 , Figure 3 is a schematic cross-sectional structure view of another perspective of the metal sleeve in a pipeline fireproof penetration device of the present application Figure 1 , Figure 4 is a schematic cross-sectional structure view of yet another perspective of the metal sleeve in a pipeline fireproof penetration device of the present application Figure 2 , Figure 5 is Figure 3 the enlarged view of the circled area A shown in Figure 3 、 Figure 4 and Figure 5 ,there is a first gap L1 between the metal sleeve 10 and the fixing mechanism 20, and a first fixing block 11 is provided on the inner side wall of the metal sleeve 10; the fixing mechanism 20 includes at least three fixing pieces 21; a second fixing block 211 is provided on the outer side wall of the fixing piece 21, and the first fixing block 11 and the second fixing block 211 are connected by an adjusting piece 30.
[0044] Here, the connection manner between the first fixing block 11, the second fixing block 211 and the adjusting piece 30 is bolt connection or pin connection, as long as it can enable the first fixing block 11, the second fixing block 211 and the adjusting piece 30 to perform axial movement around the bolt or pin.
[0045] Continue to refer to Figure 5 ,there is a second gap L2 between the first fixing block 11 and the second fixing block 211, and L1 is greater than L2 to satisfy the relative movement between the first fixing block 11, the second fixing block 211 and the adjusting piece 30. Among them, there is also a third gap L3 between adjacent fixing pieces 21.
[0046] Here, the material of the metal sleeve 10 may include but is not limited to aluminum, iron, and copper. The shape of the fixing piece 21 may be an arc shape, a square shape, a spherical shape, etc. that can closely fit the outer side wall of the pipe body 40. The shape of the adjusting piece 30 may be a waist shape, a rectangular shape, an elliptical shape, etc., as long as it can satisfy the relative movement after the first fixing block 11 and the second fixing block 211 are connected by the adjusting piece 30.
[0047] Among them, by arranging a variable-diameter fixing mechanism 20 inside the metal sleeve 10, each fixing piece 21 in the fixing mechanism 20 performs relative movement under the mutual cooperation between the first fixing block 11, the second fixing block 211 and the adjusting piece 30, and is mutually extruded under the action of bolts or pins to complete preliminary fixing, thereby realizing that within a certain range, the pipe body 40 with different diameters can be fixed at the penetration position, effectively improving the adaptability of the pipeline fireproof penetration device and reducing the use cost.
[0048] Continue to refer to Figure 2 and refer to together Figure 6 , Figure 6 is a schematic cross-sectional structure view of another perspective of the lock sleeve in a pipeline fireproof cabin-piercing device of the present application. As Figure 2 and Figure 6 shown, the lock tube mechanism 50 includes a lock head 51 and a lock sleeve 52. The lock head 51 is provided with a through hole 51A along the F1 direction. The diameter of the through hole 51A is adaptively matched with the outer diameter of the tube body 40, and the inner side wall of the lock head 51 is also provided with a thread; the lock sleeve 52 is an annular sleeve, one end of which is provided with at least three intermittent grooves 52A. At the same time, its outer side wall is also provided with a thread, realizing the threaded connection between the lock head 51 and the lock sleeve 52 to adjust the inner diameter of one end of the lock sleeve 52, so as to lock the tube body 40 passing through the lock sleeve 52.
[0049] Continue to refer to Figure 3 and refer to together Figure 7 , Figure 7 is Figure 6 the enlarged view of the circle B shown in Figure 3 and Figure 7 shown. As Figure 3 and Figure 7 shown, the inside of the lock sleeve 52 is provided with a first sleeve part 521 and a second sleeve part 522. An included angle α is formed between the first sleeve part 521 and the second sleeve part 522, wherein the included angle α is 90°-180°; the first sleeve part 521 is a flat sleeve part, and the second sleeve part 522 is an inclined sleeve part. The inner diameter of the flat sleeve part is adaptively matched with the outer diameter of the tube body 40, so as to be directly sleeved on the outer side wall of the tube body 40. The inclined sleeve part is matched with the fixing mechanism 20 to realize the abutment of the inclined sleeve part against the fixing structure, promote the movement between the fixing mechanisms 20, change the fixable inner diameter of the fixing mechanism 20, and fix the tube body 40.
[0050] Here, through the mutual cooperation of the lock head 51 and the lock sleeve 52 in the lock tube mechanism 50, after being locked at the end of the cabin-piercing distance of the tube body 40, during the cabin-piercing process of the tube body 40, the lock sleeve 52 is abutted against the fixing piece 21, and finally the fixing mechanism 20 clamps the tube body 40.
[0051] Refer to Figure 8 , Figure 8 is a schematic cross-sectional structure view of a pipeline fireproof cabin-piercing device of the present application. As Figure 8 shown, a fireproof sealing strip 60 is provided between the metal sleeve 10, the fixing mechanism 20 and the tube body 40, and a fireproof sealing glue 61 is provided between the end parts of both ends of the metal sleeve 10 and the tube body 40.
[0052] Here, by stuffing sufficient fireproof sealing strip 60 and filling fireproof sealing glue 61 in a limited space, the sealing performance and fireproof performance of the pipeline fireproof cabin-piercing device are enhanced.
[0053] For ease of understanding, the working principle of the present application is further described as follows: For the pipeline fireproof penetration device, during use, the operator first needs to adjust the accommodating space of the fixing mechanism 20 to the maximum, open a hole on the bulkhead 62 or deck that is adapted to the outer sidewall of the metal sleeve 10, and fix it on the bulkhead 62 or deck by welding. At this time, it is necessary to calculate in advance the penetration distance of the pipe body 40. At the end of the penetration distance of the pipe body 40, by using the pipe locking mechanism 50, the locking sleeve 52 is sleeved on the outer side of the pipe body 40, wherein the intermittent groove 52A faces away from the bulkhead 62 or deck, and then the locking head 51 is threadedly connected with the locking sleeve 52 to lock the pipe body 40; thereafter, the pipe body 40 is passed through the bulkhead 62 or deck for penetration until the second sleeve portion 522 of the locking sleeve 52 completely abuts against the fixing mechanism 20 and drives the fixing piece 21 in the fixing mechanism 20 to contract, so that the fixing mechanism 20 clamps the pipe body 40 up to this point; finally, sufficient fireproof sealing tape 60 is stuffed and fireproof sealant 61 is filled.
