[0039] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] In order to make the description of the present disclosure more detailed and complete, the following provides an illustrative description of the implementation and specific embodiments of the present invention; however, this is not the only form of implementing or using the specific embodiments of the present invention. The implementation covers the features of multiple specific embodiments and the method steps and sequences used to construct and operate these specific embodiments. However, other specific embodiments can also be used to achieve the same or equivalent functions and step sequences.

[0041] Please see Figures 1 to 3 The dual-axis pipeline protection device provided by the embodiment of the present invention comprises a protection sleeve 1 and a keel 2 symmetrically arranged on both sides of the protection sleeve 1 along the longitudinal direction thereof. The protection sleeve 1 wraps the pipeline, and comprises an upper cover 11 and a lower cover 12 symmetrically arranged up and down. The upper cover 11 and the lower cover 12 are flexible corrugated hoses, and the surface of the corrugated hoses is formed by wave crests and troughs that appear alternately in sequence to form a corrugated profile. The corrugated profiles of the upper cover 11 and the lower cover 12 are not completely the same, wherein the wave crest height of the upper cover 11 is less than the wave crest height of the lower cover 12, and the spacing between adjacent wave crests of the upper cover 11 is less than the spacing between adjacent wave crests of the lower cover 12. By making the wave crest height of the upper cover 11 less than the wave crest height of the lower cover 12, the resistance encountered by the protection sleeve 1 when it bends toward the upper cover 11 can be reduced, and the spacing between adjacent wave crests of the upper cover 11 is less than the spacing between adjacent wave crests of the lower cover 12, which can reduce the resistance encountered by the pipeline protection device during reciprocating motion. In an optional embodiment, the corrugated profiles of the upper cover 11 and the lower cover 12 may also be completely the same.

[0042] The two sides of the upper cover 11 extend outward to form a first extension 111, and the two sides of the lower cover 12 extend outward to form a second extension 121. The first extension 111 and the second extension 121 fit together to form a closed space for wrapping the pipeline, and the height of the cross section of the closed space is not greater than its width. The first extension 111 and the second extension 121 fit together to form a first central axis aa of the protective sleeve 1, which is the movement central axis of the protective sleeve 1.

[0043] Along the longitudinal direction of the protective sleeve 1, keels 2 are symmetrically arranged on both sides thereof, and the keel 2 includes a second central axis fitted with the first extended edge 111 and / or the second extended edge 121, and a plurality of groups of upper stops and lower stops arranged in upper and lower positions on the surface of the second central axis along the longitudinal direction thereof; the second central axis moves synchronously and co-directionally with the first central axis aa, providing the protective sleeve 1 with a curvature not less than a limited curvature facing the side of the upper cover 11, when the protective sleeve 1 bends facing the side of the upper cover 11, the upper stops gradually approach until they conflict with each other, limiting the bending of the protective sleeve 1 within a fixed curvature radius; when the protective sleeve 1 tends to bend toward the side of the lower cover 12, the lower stops conflict with each other, limiting the bending of the protective sleeve 1 toward the side of the lower cover 12.

[0044] The second center axis of the keel 2 is made of flexible material. When the protective sleeve 1 bends, the second center axis deforms flexibly and moves synchronously and in the same direction as the first center axis aa. The structural design of the keel 2 varies according to the different positions of the keel 2 in contact with the first center axis aa of the protective sleeve 1.

[0045] Please see Figures 4 to 8 The second central axis 200 of the keel 2 is placed under the second extended edge 121 of the lower cover 12 and fits with the second extended edge 121. The second central axis 200 is provided with a plurality of groups of upper stop connection columns 203 and lower stop connection columns 204 in a vertically aligned manner on its surface along its longitudinal direction. The lower stop connection columns 204 are fixedly connected to the lower stop 202, and the upper stop connection columns 203 sequentially pass through the second extended edge 121 and the first extended edge 111, and are movably connected to the upper stop 201; the gap between adjacent upper stops 201 is larger than the gap between adjacent lower stops 202.

[0046] In the embodiment of the present invention, the lower stop connection column 204 of the keel 2 is fixedly connected to the lower stop 202, and the upper stop connection column 203 is movably connected to the upper stop 201. The second central axis 200 disposed under the second extended edge 121 of the lower cover 12 moves coaxially with the first central axis aa of the protective sleeve 1, providing the protective sleeve 1 with a curvature not less than a limited bending toward the side of the upper cover 11. When the protective sleeve 1 bends toward the side of the upper cover 11, the adjacent upper stops 201 gradually approach until they conflict with each other, limiting the bending of the protective sleeve 1 within a fixed curvature radius range, and when the protective sleeve 1 tends to bend toward the side of the lower cover 12, the adjacent lower stops 202 conflict with each other, thereby limiting the bending of the protective sleeve 1 toward the side of the lower cover 12.

[0047] The upper stopper 201 movably connected to the second central axis 200 of the keel 2 includes an upper stopper 2011 and an upper pressure foot 2012 connected to the upper stopper 2011. The upper stopper 2011 has an upper arc-shaped groove 20111 recessed on its surface facing the upper cover 11, the upper pressure foot 2012 has a first through hole 20121 formed along its longitudinal direction and connected to the upper arc-shaped groove 20111, and the upper stopper connecting column 203 has an upper arc-shaped hook portion 2031 recessed along its longitudinal direction. The upper stopper connecting column 203 is inserted into the first through hole 20121, so that the upper arc-shaped hook portion 2031 is buckled and fixed to the upper arc-shaped groove 20111. The upper stopper 2011 is also provided with an upper buckle hole 20112, which is offset from the center line of the upper stopper 2011, so that the force point of the upper stopper 201 deviates from the center line during the reciprocating motion of the pipeline protection device, thereby preventing the upper stopper 201 from falling off. A connecting line is also provided between adjacent upper stops 201, which not only facilitates the quick installation of the upper stopper 201, but also allows the upper stopper 201 to be quickly found when the upper stopper 201 falls off during the operation of the pipeline protection device due to the existence of the connecting line.

[0048] The lower stopper 202 fixedly connected to the second central axis 200 of the keel 2 is vertically connected to the lower stopper connecting column 204 and parallel to the second central axis 200. The lower stopper 202 has a convex portion on one end face along the longitudinal direction of the second central axis 200, and has a concave portion that fits with the convex portion on the other opposite end face. The bending of the protective sleeve 1 facing the lower cover 102 is limited by the fit of the convex portion and the concave portion on the adjacent lower stopper 202. In the embodiment of the present invention, the main body of the lower stopper 202 is a rectangular block. In an optional embodiment, the main body of the lower stopper 202 can be other shapes, and the two end faces of the lower stopper 202 can also be other shapes, which is not limited by the present invention.

[0049] The dual-axis pipeline protection device provided in the embodiment of the present invention forms dual-axis co-directional motion by synchronously and co-directionally moving the second central axis of the keel providing a stop function and the first central axis wrapping the pipeline protection sleeve, so that the pipeline protection device can simultaneously meet the requirements of full closure, higher overhead length, smaller bending radius, and stable performance, and is suitable for narrow spaces.

[0050] Please see Fig. 9 and Fig.10, the second central axis 210 of the keel 2 is placed on the first extended edge 111 of the upper cover 11, and fits with the first extended edge 111. The second central axis 210 is provided with a plurality of groups of upper stop connecting columns 213 and lower stop connecting columns 214 on its surface in the longitudinal direction thereof, the upper stop connecting columns 213 are fixedly connected to the upper stop 211, and the lower stop connecting columns 214 sequentially pass through the first extended edge 111 and the second extended edge 121, and are movably connected to the lower stop 212. The gap between adjacent upper stops 211 is greater than the gap between adjacent lower stops 212. In the embodiment of the present invention, the upper stop connecting column 213 of the keel 2 is fixedly connected to the upper stop 211, and the lower stop connecting column 214 is movably connected to the lower stop 213. Among them, the lower stop 212 and the lower stop connecting column 214 are respectively connected to the upper stop 211 and the lower stop 211. Figure 5 The upper stop 201 and the upper stop connecting column 213 in the keel of the illustrated embodiment have the same structure. The lower stop 212 includes a lower stop portion and a lower pressure foot portion connected to the lower stop portion. The surface of the lower stop portion facing the lower cover is recessed with a lower arc-shaped groove, and the lower pressure foot portion is provided with a second through hole along its longitudinal direction and is connected to the lower arc-shaped groove; the surface of the lower stop connecting column is recessed along its longitudinal direction to form a lower arc-shaped hook portion; the lower stop connecting column is inserted into the second through hole, so that the lower arc-shaped hook portion is buckled and fixed with the lower arc-shaped groove, and a lower buckle hole is also provided on the lower stop portion, and the lower buckle hole deviates from the center line of the lower stop portion, which can be referred to Figure 5 The keel in the illustrated embodiment shows the structure of the upper stopper 201 and the upper stopper connecting column 203 and the connection relationship therebetween. A connecting line is provided between adjacent lower stops 212, which not only facilitates the quick installation of the lower stops 212, but also allows the lower stops 212 to be found quickly when they fall during the operation of the pipeline protection device due to the existence of the connecting line.

[0051] In the embodiment of the present invention, the lower stopper 212 and the lower stopper connecting column 214 are respectively connected to Figure 5 The upper stopper 201 and the upper stopper connecting column 213 in the keel of the embodiment shown in the figure have the same structure, while the upper stopper 211 and the upper stopper connecting column 213 are respectively Figure 5 The structures of the lower stopper 202 and the lower stopper connecting column 204 in the keel of the embodiment shown are the same. It can be seen that the keel structure in the embodiment of the present invention can be obtained by Figure 5 The keel of the illustrated embodiment reduces the gap between adjacent lower stops 202 and expands the gap between adjacent upper stops 201, so that the gap between adjacent lower stops 202 is smaller than the gap between adjacent upper stops 201, and the bending radius of the pipeline protection device is smaller.

[0052] The dual-axis pipeline protection device provided in the embodiment of the present invention forms dual-axis co-directional motion by synchronously and co-directionally moving the second central axis of the keel providing a stop function and the first central axis wrapping the pipeline protection sleeve, so that the pipeline protection device can simultaneously meet the requirements of full closure, higher overhead length, smaller bending radius, and stable performance, and is suitable for narrow spaces.

[0053] Please see Fig.11 The second central axis 220 of the keel 2 is placed between the first extension 111 and the second extension 121, and fits with the first extension 111 and the second extension 121 respectively. The second central axis 220 is provided with a plurality of groups of upper stop connection columns 223 and lower stop connection columns 224 on its surface in the longitudinal direction thereof. The upper stop connection columns 223 pass through the first extension 111 to be movably connected to the upper stop 221, and the lower stop connection columns 224 pass through the second extension 121 to be movably connected to the lower stop 222. The gap between adjacent upper stops 221 is larger than the gap between adjacent lower stops 222. Connecting wires are provided between adjacent upper stops 221 and adjacent lower stops 222, which not only facilitates quick installation, but also facilitates quick finding of the upper stop 221 and the lower stop 222 when the upper stop 221 and the lower stop 222 fall off during the operation of the pipeline protection device due to the existence of the connecting wires.

[0054] In the embodiment of the present invention, the upper stopper connecting column 223 of the keel 2 is movably connected to the upper stopper 221, and the lower stopper connecting column 224 is movably connected to the lower stopper 222. Figure 5 The structure of the upper stopper 201 in the keel of the embodiment shown is the same, and the structures of the upper stopper connecting column 223 and the lower stopper connecting column 224 are the same as those of the embodiment shown in FIG. Figure 5 The structure of the upper stopper connecting column 203 in the keel of the embodiment shown is the same.
