[0002] The green outer membrane UV-cured in-situ repair hose is a technology used for pipeline repair. It uses a special hose material with a light-curing resin impregnated between the inner and outer membranes. During the construction process, the hose is pulled into the original pipeline and the resin is cured by ultraviolet light, thereby forming a new, strong and durable lining inside the pipeline to achieve the purpose of pipeline repair.

[0003] During the construction process, some key steps need to be paid attention to, such as hose curing. After the hose is pulled into the predetermined position, compressed air is used to expand the hose and make it close to the inner wall of the pipe. During the curing process, a certain compressed air pressure needs to be maintained to ensure that the hose is in close contact with the inner wall of the pipe. Before ventilation, the hose and the end need to be connected and fixed. The existing fixing method is that multiple staff members use multiple clips to clamp the end of the hose, and then several people cooperate to open the end of the hose, and then move the end of the hose close to the end to connect the hose and the end. This process is not only labor-intensive, but also cumbersome to operate, and it is more inconvenient to operate when encountering large hoses; at the same time, the sealing operation of the hose and the end after the connection is completed is also more troublesome.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a UV in-situ curing repair hose with a green outer film, comprising a hose body 1, a sealing end body 2 is installed at one end of the hose body 1, a ferrule 3 is installed at one end of the hose body 1, a branch connecting pipe 4 is fixedly connected to the ferrule 3, a one-way valve body 5 is installed on the side of the branch connecting pipe 4 close to the sealing end body 2, a connecting mechanism 6 is fixedly connected to the side of the one-way valve body 5 close to the sealing end body 2, an opening auxiliary mechanism, the opening auxiliary mechanism is used to open the opening of the hose body 1, the opening auxiliary mechanism is connected to the hose body 1, and a tightening mechanism is used to tighten the opening of the hose body 1, and the tightening mechanism is connected to the hose body 1. The ferrule 3 is annularly sleeved on the end of the hose body 1. The device can first bend the end of the hose body 1 to make the ferrule 3 The vent pipe 4 is placed at the bent part of the hose body 1, and then the branch connecting pipe 4 and the vent pipe opening on the sealing end head body 2 are connected through the connecting mechanism 6, and then the knob on the one-way valve body 5 is turned to open, so that the pipe opening on the sealing end head body 2 and the branch connecting pipe 4 are connected, and the sealing end head body 2 is ventilated, so that the airflow enters the ring 3 along the branch connecting pipe 4, and the opening of the hose body 1 is quickly expanded by utilizing the expansion of the ring 3, so that the end of the hose body 1 is quickly sleeved and installed on the sealing end head body 2, and after the installation is completed, the connection between the hose body 1 and the sealing end head body 2 can also be quickly sealed, as described below for details, the device is not only simple in structure, but also quick and convenient to operate, and saves a lot of manpower, effectively increases the work efficiency of installing the hose body 1 and the sealing end head body 2, and the practicability of the device is good.

[0041] like Figures 1 to 6As shown, the opening auxiliary mechanism includes a first skeleton 7 installed on the hose body 1, and anti-slip sheets 8 are fixedly connected to the upper and lower sides of the first skeleton 7, and the two side ends of the first skeleton 7 are fixedly connected to the first guide parts 9, and the two side ends of the first skeleton 7 are provided with reinforcement sheets 10. The first skeleton 7 is made of plastic material, and first lightweight grooves 11 are equidistantly provided on the first skeleton 7. The first skeleton 7 is three groups equidistantly arranged at the end of the hose body 1. The cross-section of the first skeleton 7 tends to be C-shaped, and the top length of the first skeleton 7 is greater than the bottom length of the first skeleton 7. By making the first skeleton 7 fit the user's hand mouth, the thumb of the hand is located on a group of anti-slip sheets 8 at the bottom of the first skeleton 7, and the other four fingers of the hand are located on a group of anti-slip sheets 8 at the top of the first skeleton 7, and then The first skeleton 7 is aligned with the end of the hose body 1, so that the first skeleton 7 is quickly installed to the edge of the hose body 1 along the guidance of the first guide part 9. Under the action of the extrusion force, the first guide part 9 and the reinforcing plate 10 are deformed, so that the first skeleton 7 is clamped more tightly on the end of the hose body 1, so that the ring 3 can be stably set on the bending part of the hose body 1, and the ring 3 will not be separated from the bending part of the hose body 1 during ventilation and expansion. The first lightweight groove 11 opened on the first skeleton 7 not only reduces the weight of the first skeleton 7, but also saves the production cost of the first skeleton 7, and makes the first skeleton 7 more likely to produce slight deformation when squeezed, so that the installation of the first skeleton 7 is faster, and the coordinated use of the structures further makes the use effect of the device better.

[0042] like Figures 5 to 10As shown, the tightening mechanism includes a second skeleton 12 installed on the hose body 1, the second skeleton 12 is fixedly connected to a limiting frame 13 on the upper part of one side away from the sealing end body 2, a tightening belt 21 is installed on the hose body 1, and a connecting ring 22 is fixedly connected to one end of the tightening belt 21, and an outer frame 23 is installed on the side of the hose body 1 close to the tightening belt 21, and a rotating component is arranged in the outer frame 23, and the rotating component is connected to the outer frame 23. The second skeleton 12 is divided into three groups, and its installation position corresponds to the installation position of the three groups of first skeletons 7, and the second skeleton 12 is located between the first skeleton 7 and the tightening belt 21, and is used to tighten the first skeleton 7 is associated with the tightening belt 21. The structure enables the second skeleton 12 to be quickly installed on the tightening belt 21 by using the second skeleton 12 in conjunction with the limiting frame 13, and then adjusts the distance between the three groups of second skeletons 12 to align the second skeleton 12 with the first skeleton 7, and then puts the side of the second skeleton 12 away from the tightening belt 21 in close contact with the first skeleton 7, so that the first skeleton 7 and the tightening belt 21 are associated together, so that the tightening belt 21 squeezes the first skeleton 7 when tightening, and utilizes the deformation of the first skeleton 7 to squeeze the ring 3 set in the bending part of the hose body 1, so that the ring 3 has a certain sealing effect on the opening of the hose body 1. The connecting ring 22 and the outer frame 23 on the tightening band 21 are both installed on one end of the tightening band 21. First, insert one end of the tightening band 21 into the connecting ring 22, and then use the outer frame 23 to clamp the end head. Then, by using the rotating assembly in the outer frame 23, the tightening band 21 can be tightened, thereby achieving the fixing and sealing of the connection between the hose body 1 and the sealing end body 2 by the tightening band 21. For details, see below. Not only can the connection between the hose body 1 and the sealing end body 2 be quickly sealed, but the operation is also quick and simple, and the sealing effect is good. In addition, the mutual cooperation between the structures further makes the use effect of the device better.

[0043] Furthermore, the second frame 12 is provided with a bending portion 14, a second guide portion 15 is provided on the side of the second frame 12 close to the sealing end head body 2, a third guide portion 18 is provided on the end of the second frame 12 close to the limiting frame 13, a third cavity 19 is provided on the end of the limiting frame 13, a first cavity 16 is provided on one side of the sealing end head body 2, a second cavity 17 is provided on the side of the second frame 12 close to the sealing end head body 2, and a second lightweight groove 20 is provided on the second frame 12 and the limiting frame 13. By pressing the second frame 12 against the first frame 7 and applying a force to the second frame 12 to approach the first frame 7, the bending portion 14 is bent by force, thereby causing the second frame 12 to produce a stronger complex Elastic force makes the second skeleton 12 have a better pressing effect on the first skeleton 7, further makes the first skeleton 7 deform more, and then the ring 3 is squeezed and deformed by the first skeleton 7, and the design of the first cavity 16 and the second cavity 17 makes the corresponding part of the second skeleton 12 deform better, so that this part of the second skeleton 12 has a further squeezing effect on the first skeleton 7, and by utilizing the principle of better stability of the triangle, the strength of the second skeleton 12 in the second cavity 17 is made greater than that in the first cavity 16, so that the second skeleton 12 is easier to deform corresponding to the first cavity 16, and the complex elastic force generated by the deformation of the second skeleton 12 is used to squeeze the first skeleton 7, so that the first skeleton 7 is better tightened. The use of the ring 3 in conjunction with the first skeleton 7 achieves a better sealing effect on the end portion of the hose body 1, and the design of the third guide portion 18 and the third cavity 19 allows the tightening band 21 to be installed more quickly into the second skeleton 12 and the limiting frame 13. After the installation is completed, the restorative elastic force of the second skeleton 12 and the limiting frame 13 clamps the tightening band 21, so that the tightening band 21 can be limited to a certain point on the tightening band 21 without being affected by external forces.

[0044] like Figures 8 to 10As shown, the rotating assembly includes a rotating shaft body 24 installed on the outer frame 23, a clip 25 is fixedly connected to the rotating shaft body 24, a gear body 26 is fixedly connected to the side of the rotating shaft body 24 away from the clip 25, a first bevel gear 27 is installed on the side of the outer frame 23 away from the rotating shaft body 24 through the rotating shaft, a second bevel gear 28 is installed on the top of the outer frame 23 through the rotating shaft, a rotating rod 29 is installed on the top of the second bevel gear 28, a limiting rod 30 is installed on the top of the outer frame 23, and a torsion spring body 31 is installed on the middle side of the limiting rod 30 close to the second bevel gear 28. The clip 25 and the rotating shaft body 24 are integrally constructed, the outer frame 23 is rotatably connected to the rotating shaft body 24, the clip 25 is narrow in the middle and wide on both sides, and this shape design makes it easier to fix the end of the tightening belt 21 in the outer frame 23, and the shape design of the outer frame 23 is used to squeeze the end of the tightening belt 21. The limiting effect is to rotate the rotating rod 29 so that the rotating rod 29 drives the second bevel gear 28 to rotate, thereby rotating the first bevel gear 27 meshing with the second bevel gear 28, and then rotating the gear body 26 meshing with the first bevel gear 27, so that the gear body 26 drives the rotating shaft body 24 and the outer frame 23 to rotate, so that the outer frame 23 tightens one end of the tightening band 21 to tighten the tightening band 21, so that the tightening band 21 seals the connection between the hose body 1 and the sealing end head body 2. During this period, when the tightening band 21 is tightened, it drives the second skeleton 12 to tighten, so that the extrusion force of the second skeleton 12 on the first skeleton 7 is further strengthened, and the extrusion of the first skeleton 7 on the ring 3 is further strengthened, so that the sealing strength of the ring 3 on the opening of the hose body 1 is better. With the use of the ring 3 and the tightening band 21, the device can quickly and effectively seal the connection between the hose body 1 and the sealing end head body 2, so that the practicability of the device is better.

[0045] Furthermore, the cross-section of the rotating rod 29 is circular, the outer wall of the rotating rod 29 is provided with an anti-skid pad, and the outer wall of the anti-skid pad is provided with a wavy anti-skid pattern, the size of the second bevel gear 28 is larger than the size of the first bevel gear 27, the size of the first bevel gear 27 is larger than the size of the gear body 26, and the adjacent two groups of the second bevel gear 28, the first bevel gear 27 and the gear body 26 are meshed with each other. Through the shape design of the rotating rod 29 and the wrapped protective pad, the touch of the rotating rod 29 is better, and it is not easy to slip sideways when the rotating rod 29 is rotated. In addition, the size design of the second bevel gear 28, the first bevel gear 27 and the gear body 26 makes it easier to rotate the rotating rod 29, solving the problem of cumbersome and laborious operation in the past. The end of the limiting rod 30 close to the second bevel gear 28 is meshed with the second bevel gear 28 in a natural state. The connection and working principle of the second bevel gear 28, the limiting rod 30 and the torsion spring body 31 is the ratchet principle. No further elaboration is given here. The limiting rod 30 and the torsion spring body 31 can produce a quick fixed limiting effect on the tightening belt 21 after the tightening belt 21 is tightened to the required length. The structure is simple and easy to use.

[0046] The workflow of the technical solution of the present invention is as follows:

[0047] When in use, first place the sealing end body 2 at the end of the hose body 1, then bend the end of the hose body 1 outward to form a cavity, then put the ring 3 on the outer wall of the hose body 1, and then place the ring 3 in the cavity formed by the bending of the hose body 1, so that the branch connecting pipe 4 extends along the edge of the hose body 1 to the vent pipe connection of the sealing end body 2, and then use the connecting mechanism 6 to connect the branch connecting pipe 4 and the vent pipe opening on the sealing end body 2.

[0048] Then, the user places the thumb of the hand on a group of anti-slip sheets 8 at the bottom of the first skeleton 7, and the other four fingers of the hand on a group of anti-slip sheets 8 at the top of the first skeleton 7, and then aligns the first skeleton 7 with the end of the hose body 1, so that the first skeleton 7 is quickly installed to the edge of the hose body 1 along the guidance of the first guide part 9. Under the action of the extrusion force, the first guide part 9 and the reinforcing sheet 10 are deformed, so that the first skeleton 7 is tightly clamped on the end of the hose body 1, so that the ring 3 can be stably set at the bending part of the hose body 1, and then the knob on the one-way valve body 5 is turned to open, so that the pipe opening on the sealing end body 2 and the branch connecting pipe 4 are connected, and air is ventilated into the sealing end body 2, so that the airflow enters the ring 3 along the branch connecting pipe 4, and the expansion of the ring 3 is used to quickly expand the opening of the hose body 1. After the opening of the hose body 1 is expanded to a diameter larger than the diameter of the sealing end body 2, the inflation is stopped, and the knob on the one-way valve body 5 is closed.

[0049] Then, the sealing end body 2 is moved closer to the hose body 1, so that the sealing end body 2 is quickly inserted into the hose body 1, and then the knob on the one-way valve body 5 is opened again, so that part of the gas in the ferrule 3 is discharged outward, and then the one-way valve body 5 is closed. At this time, the hose body 1 is subjected to the restorative elastic force and fits the outer wall of the sealing end body 2. Then the second skeleton 12 is aligned with the first skeleton 7, and the side of the second skeleton 12 away from the tightening band 21 is pressed against the first skeleton 7 by the guidance of the second guide part 15, so that the first skeleton 7 and the tightening band 21 are associated together, and the bending part 14 and the reinforcing plate 10 are aligned. Then the tightening band 21 is set around the outer wall of the hose body 1, and one end of the tightening band 21 is inserted into the connecting ring 22, and then the end is clamped by the outer frame 23, so that the tightening band 21 is annular.

[0050] The rotating rod 29 is rotated to make the rotating rod 29 drive the second bevel gear 28 to rotate, thereby rotating the first bevel gear 27 meshing with the second bevel gear 28, and then rotating the gear body 26 meshing with the first bevel gear 27, so that the gear body 26 drives the rotating shaft body 24 and the outer frame 23 to rotate, so that the outer frame 23 tightens one end of the tightening band 21 to tighten the tightening band 21 in an annular manner, so that the tightening band 21 squeezes and seals the connection between the hose body 1 and the sealing end head body 2. During the rotation of the second bevel gear 28, the limit rod 30 is subjected to force fluctuations, and the torsion spring body 31 is deformed by the force. When the tightening band 21 is tightened to the required length, the limit rod 30 and the torsion spring body 31 have a quick fixed limit effect on the tightening band 21. At the same time, when the tightening belt 21 is tightened, the second frame 12 is driven to tighten toward the side close to the center of the hose body 1, so that the second frame 12 is deformed, and the extrusion force of the second frame 12 on the first frame 7 is further strengthened, so that the tightening belt 21 squeezes the first frame 7 when tightened, and the deformation of the first frame 7 is used to squeeze the ferrule 3 set in the bending part of the hose body 1, so that the ferrule 3 has a further sealing effect on the opening of the hose body 1. The tightening belt 21 and the ferrule 3 are used to quickly double-seal the connection between the hose body 1 and the sealing end body 2, so that the sealing effect of the connection is better, the operation is simple, and the practicability of the device is better.
