[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A pipeline safety protection device includes a pipeline body 1. Two groups of pipeline bodies 1 are provided, and welding parts 2 are distributed on the side where the two groups of pipeline bodies 1 are close to each other. Two groups of protective sleeves 3 are provided on the outer side of the welding parts 2, and the ends of the two groups of protective sleeves 3 are symmetrically connected with connecting plates 4. The connecting plates 4 are connected by bolts, and the connecting plates 4 where the two groups of protective sleeves 3 are close to each other are connected by bolts. By setting the connecting plates 4, the two groups of protective sleeves 3 can be quickly connected and disassembled.

[0023] Further, see Figure 2 and Figure 3 It can be seen that the inner side of the protective sleeve 3 is symmetrically distributed with abutment blocks 6, and the inner wall of the abutment blocks 6 is set as an arc structure. When in use, the setting of the abutment blocks 6 can effectively ensure the tightness of the two groups of protective sleeves 3 clamped on the outer side of the welding part 2.

[0024] Further, see Figure 3 and Figure 4 It can be known that rotating rollers 7 are evenly distributed on the outside of the two groups of protective sleeves 3, and the ends of the rotating rollers 7 are connected to connecting rods 8 through bearings. A support plate 9 is provided on the side of the connecting rod 8 away from the rotating rollers 7, and the support plate 9 and the side of the protective sleeve 3 are fixedly connected. Since the rotating rollers 7 are connected to the connecting rods 8 through bearings, the rotating rollers 7 rotate when subjected to force. In addition, by setting the support plate 9, the support work of the rotating rollers 7 can be achieved.

[0025] Further, see Figure 3 and Figure 4 It can be known that a protective block 10 is sleeved on the outer side of the rotating roller 7, and the longitudinal section of the protective block 10 is arranged as a ring structure. When in use, the protective block 10 arranged in the ring structure can achieve preliminary protection of the rotating roller 7.

[0026] Further, see Figure 4 It can be known that rectangular grooves are respectively provided inside the support plate 9, and a rotating shaft 11 is inserted inside the rectangular groove, a bevel gear set 12 is connected to the inner side of the rotating shaft 11, and a screw 13 is inserted inside the bevel gear set 12, and screw sleeves 14 are symmetrically distributed on the outer side of the screw 13, and the screw sleeves 14 extend to the outside of the rectangular groove and are connected to the limiting plate 15, and the rotating shaft 11 extends to the outside of the rectangular groove and is connected to a knob. When in use, the staff can turn the knob to drive the synchronous rotation of the bevel gear set 12. In addition, since the bevel gear set 12 is composed of two groups of bevel gears, and the two groups of bevel gears are respectively sleeved on the inner side of the rotating shaft 11 and the outer side of the screw 13, the screw 13 and the rotating shaft 11 can be reversed. Rotation, in addition, since two groups of screw sleeves 14 are provided on the outer side of the screw 13, and since two groups of external threads with opposite rotation directions are provided on the outer side of the screw 13, the two groups of limiting plates 15 can move in opposite directions when subjected to force.

[0027] Further, see Figure 4 It can be known that a rectangular rod is connected to the side of the limit plate 15 away from the rotating roller 7, and a slideway adapted to the rectangular rod is opened inside the support plate 9. Through the mutual cooperation of the rectangular rod and the slideway, the screw sleeve 14 and the limit plate 15 can be docked, and the rotating screw sleeve 14 can be guided to prevent the screw sleeve 14 from idling.

[0028] Further, see Figure 1 and Figure 2 It can be seen that the end of the protective sleeve 3 is symmetrically connected with the rubber sleeve 5, and the inner wall of the rubber sleeve 5 is tightly fitted with the outer surface of the pipe body 1. When in use, the two groups of rubber sleeves 5 set at the end of the protective sleeve 3 can reduce the gap between the protective sleeve 3 and the pipe body 1, and the sealing effect of the welding part 2 can be further achieved.

[0029] Working principle: When the utility model is used, the staff can first connect the pipe bodies 1 through welding, so that the side of the pipe bodies 1 that is close to each other will produce a welding part 2. After the pipe bodies 1 are spliced ​​together, the staff can sequentially cover the outer side of the welding part 2 with the protective cover 3, and make the connecting plates 4 at the ends of the protective cover 3 close to each other. Then the staff can use bolts to connect the protective cover 3 to achieve the limit of the protective cover 3. During the use of the pipe body 1, the protection of the welding part 2 can be achieved through the setting of the protective cover 3. In addition, when there is When a foreign object approaches the welding portion 2, the external force will first act on the rotating roller 7. At this time, the rotating roller 7 can be rotated under force to reduce the external force. When part of the rotating roller 7 is damaged, the staff can drive the screw 13 to reverse rotation by rotating the rotating shaft 11 and setting the bevel gear set 12. At this time, the screw 13 and the screw sleeve 14 are threadedly matched, so that the two sets of limit plates 15 are forced to move away from each other. At this time, the staff can remove the connecting rod 8 from the inner side of the limit plate 15 to replace the damaged rotating roller 7. The above is the entire working principle of the utility model.
