Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a drainage pipeline repair device. Background Art

[0002] Pipeline repair refers to the use of various technologies to restore damaged and leaking transmission pipelines to their normal function. The repair includes two technologies: external anti-corrosion layer repair and internal repair. There are many ways to repair pipelines. Before planning the repair, it is necessary to evaluate the effectiveness, long-term, reliability, safety and cost of different pipeline repair plans based on the condition of your own pipeline, so as to determine the most suitable repair plan.

[0003] Through searching, it was found that Chinese patent announcement number: CN213089145U discloses a drainage pipe repair device, which belongs to the field of pipe repair technology, including a connecting pipe, an air bag and a pouring pipe. Two limit plates are arranged on the connecting pipe at intervals, and multiple rollers are installed on the two limit plates. The air bag is arranged around the outside of the connecting pipe and is located between the two limit plates; a material storage part is arranged along the outer periphery of the air bag, and the material storage part is recessed toward the inner side of the air bag; the material storage part is used to cover the felt cylinder; the material storage part is used to form a pouring cavity with the inner wall of the pipe, and an air outlet groove connected to the pouring cavity is opened on the top of the air bag. The pouring pipe is passed through the connecting pipe, and the pouring pipe The end of the utility model passes through the connecting pipe and is connected to the pouring cavity, which is used to transport the coagulant to the pouring cavity. In the drainage pipe repair device provided by the utility model, after the airbag drives the felt cylinder to move to the specified position, the pouring pipe transports the coagulant, thereby avoiding immersing the felt cylinder in the coagulant in advance, resulting in the loss of the coagulant and the premature solidification of the coagulant, thereby improving the maintenance effect. However, after the repair of the utility model, when the roller passes through the felt cylinder, it will be squeezed by the felt cylinder, so that the position of the roller will change, so that it can be taken out.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 A drainage pipe repair device in this embodiment includes a drainage pipe body 1. An airbag 2 is provided in the inner cavity of the drainage pipe body 1. A felt tube 3 is sleeved in the middle of the outer surface of the airbag 2. A removal mechanism 4 for facilitating the removal of the airbag 2 is provided on the left and right sides of the airbag 2. A protective mechanism 5 for improving the surface strength of the airbag 2 is provided on the outer surface of the airbag 2.

[0028] In this embodiment, a connecting tube is fixed to the inner cavity of the airbag 2, and a casting tube is provided in the inner cavity of the connecting tube. The other end of the casting tube passes through the airbag 2 and extends to the outside of the airbag 2. Sealing rings are provided at the connections between the connecting tube, the casting tube and the airbag 2.

[0029] See also Figures 2 to 3 In order to facilitate the removal of the airbag 2, the removal mechanism 4 in this embodiment includes a fixing plate 41, a double-axis motor 42, two screws 43, two screw sleeves 44, two connecting plates 45, two rubber blocks 46 and two rollers 47. The fixing plate 41 is fixed to one side of the airbag 2, the double-axis motor 42 is fixed to the middle of the inner back wall of the fixing plate 41, the screw 43 is fixedly connected to the output shaft of the double-axis motor 42, the screw sleeve 44 is threadedly connected to the screw 43, the double-axis motor 42 is started, the output shaft of the double-axis motor 42 rotates and drives the two screws 43 to rotate, and the rotation of the two screws 43 causes the threaded connection The screw sleeve 44 connected to its surface moves, and the connecting plate 45 is fixed on one side of the screw sleeve 44. The side of the connecting plate 45 away from the screw sleeve 44 penetrates the fixing plate 41 and extends to the side away from the fixing plate 41. Two rubber blocks 46 are fixed on the opposite sides of the connecting plates 45 at the upper and lower ends. The set rubber blocks 46 can reduce the impact of the roller 47 on the drainage pipe body 1 when rolling. The roller 47 is fixed on the opposite sides of the two rubber blocks 46. The movement of the two screw sleeves 44 drives the connecting plate 45 to move. The movement of the connecting plate 45 can drive the rubber block 46 and the roller 47 to move until they are adjusted to a suitable distance.

[0030] Among them, the fixing plate 41 is located on the rear side of the connecting pipe, and sliding holes are opened on the top and bottom of the opposite sides of the left and right fixing plates 41. The size of the connecting plate 45 is adapted to the size of the inner cavity of the sliding hole. The screw 43 is rotatably connected to the opposite side of the inner bottom wall or the inner top wall of the fixing plate 41 through a bearing, and the threads at the upper and lower ends of the screw 43 are of opposite structure.

[0031] In this embodiment, the top and bottom of the inner wall on the opposite side of the fixed plate 41 are fixed with limit strips, and the opposite sides of the left and right screw sleeves 44 are fixed with limit rods. The limit rods make linear up and down motions in the inner cavity of the limit strips. The two screw sleeves 44 are symmetrically distributed at the upper and lower ends of the transverse center axis of the screw rod 43, and the two screw sleeves 44 make relative or opposite motions on the outer surface of the screw rod 43.

[0032] It can be understood that the airbag 2 is brought into the ruptured part of the inner cavity of the drainage pipe body 1 by the roller 47, at which time the felt tube 3 is located on the outside of the airbag 2, and then the coagulant is introduced into the depression on the outer surface of the airbag 2 through the pouring tube and solidified with the felt tube 3. After the felt tube 3 is fixed, the distance between the rollers 47 can be adjusted and then the airbag 2 can be shrunk and taken out to avoid touching the felt tube 3.

[0033] See also Figure 4 In order to enhance the strength of the airbag 2, the protective mechanism 5 in this embodiment includes an adhesive layer 51, a corrosion-resistant layer 52 and a wear-resistant layer 53. The adhesive layer 51 is arranged on the outside of the airbag 2, the corrosion-resistant layer 52 is arranged on the outside of the adhesive layer 51, and the wear-resistant layer 53 is arranged on the outside of the corrosion-resistant layer 52. The wear-resistant layer 53 is a polyurethane layer. The polyurethane layer has extremely high wear resistance, which makes it very suitable for applications that need to withstand friction, such as the outer surface of the airbag 2.

[0034] In this embodiment, the bonding layer 51 is a cyanoacrylate layer. Cyanoacrylate is usually called super glue or instant glue. It is a fast-curing adhesive. The cyanoacrylate monomer contained in it quickly polymerizes when exposed to moisture to form a strong bonding layer 51. The corrosion-resistant layer 52 is an epoxy resin layer. The epoxy resin layer is a widely used protective coating. The epoxy resin layer has high wear resistance and is suitable for use on surfaces that are often subject to friction or wear. The epoxy resin layer has good weather resistance and aging resistance, and can provide long-term protection.

[0035] The working principle of the above embodiment is:

[0036] (1) When in use, the distance between the rollers 47 can be adjusted to a suitable distance. First, the dual-axis motor 42 is started. The output shaft of the dual-axis motor 42 rotates and then drives the two screws 43 to rotate. The rotation of the two screws 43 causes the screw sleeves 44 threadedly connected to their surfaces to move. At this time, the two screw sleeves 44 make relative motion or move away from each other. The movement of the two screw sleeves 44 drives the connecting plate 45 to move. The movement of the connecting plate 45 can drive the rubber block 46 and the roller 47 to move until the distance is adjusted to a suitable distance. Then, the airbag 2 is brought into the rupture of the inner cavity of the drainage pipe body 1 by the roller 47. At this time, the felt tube 3 is located on the outside of the airbag 2. Then, the coagulant is introduced into the depression on the outer surface of the airbag 2 through the casting tube and solidified with the felt tube 3. After the felt tube 3 is fixed, the distance between the rollers 47 can be adjusted and then the airbag 2 is shrunk and taken out to avoid touching the felt tube 3.

[0037] (2) The adhesive layer 51 is a cyanoacrylate layer. Cyanoacrylate is usually called super glue or instant glue. It is a fast-curing adhesive. The cyanoacrylate monomer contained in it quickly polymerizes when it comes into contact with moisture to form a strong adhesive layer 51. The corrosion-resistant layer 52 is an epoxy resin layer. The epoxy resin layer is a widely used protective coating. The epoxy resin layer has high wear resistance and is suitable for use on surfaces that are often subjected to friction or wear. The epoxy resin layer has good weather resistance and aging resistance and can provide long-term protection. The wear-resistant layer 53 is a polyurethane layer. The polyurethane layer has extremely high wear resistance, which makes it very suitable for applications that need to withstand friction, such as the outer surface of the airbag 2.
