Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a green and environment-friendly water supply and drainage pipeline repair device. Background Technique

[0002] During the long-term use of water supply and drainage pipelines, the pipelines are prone to electrochemical corrosion by the soil layer, resulting in damage or aging of some structures, and local repair of the pipelines is required. In traditional repair methods, the mixed glue is usually infiltrated on the glass fiber material and then closely attached to the inner wall of the pipeline at the damaged part. Due to the different positions of the damaged parts of the pipeline, when the glass fiber material moves on the inner wall of the pipeline, it is easy to come into contact with the inner wall of the pipeline, thereby affecting the repair effect of the glass fiber material on the damaged part of the pipeline.

[0003] The patent with the authorization announcement number CN217653503U discloses a local repair device for drainage pipelines. Through the buffer mechanism, the two upper pulleys are in contact with the inner wall of the sewage pipe, so that the device is convenient to adapt to sewage pipes of different sizes, and the glass fiber material on the airbag is not easy to come into contact with the inner wall of the sewage pipe, thereby ensuring the repair effect on the sewage pipe.

[0004] However, this device does not have a cleaning component. When the device moves to the damaged part of the pipeline, the dirt attached to the inner wall of the pipeline will still affect the fitting effect of the glass fiber material, and ultimately affect the repair quality. Content of the Utility Model

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a green and environment-friendly water supply and drainage pipeline repair device.

[0006] Technical Solution: A green and environment-friendly water supply and drainage pipeline repair device includes two connecting plates. An airbag one is arranged between the two connecting plates. A repair material is wound on the surface of the airbag one. A cleaning mechanism is installed on the left connecting plate. The cleaning mechanism is used to clean the dirt on the inner wall of the pipeline. An airbag two is installed on the right connecting plate. The airbag two is used to discharge the dirt after inflation. An elastic bag is sleeved outside the airbag one. The elastic bag is used to seal and protect the repair material. The left end of the elastic bag is fixedly connected to the left connecting plate. The right end of the elastic bag is provided with a bag mouth. A plurality of connecting pieces are arranged at intervals in the circumferential direction of the bag mouth of the elastic bag. A locking and retracting mechanism is arranged on the right connecting plate. The locking and retracting mechanism cooperates with the connecting pieces to keep the bag mouth of the elastic bag fixed at the right end of the airbag one. When the locking and retracting mechanism releases the fixation of the bag mouth of the elastic bag, the elastic force of the elastic bag is sufficient to make its bag mouth completely move to the left end of the airbag one.

[0007] Furthermore, the cleaning mechanism includes a cleaning rod and a motor one. A motor one is installed on the left connecting plate. The output shaft of the motor is fixedly connected with a mounting block. At least two cleaning rods are circumferentially installed on the mounting block.

[0008] Furthermore, a plurality of rollers are circumferentially arranged at intervals on both connecting plates. The rollers are connected to the connecting plates through telescopic rods, and the cleaning rod is connected to the mounting block through a telescopic rod.

[0009] Furthermore, the locking and retracting mechanism includes a plurality of fixing blocks. The plurality of fixing blocks are fixedly connected circumferentially at intervals on the right connecting plate. The fixing blocks correspond to the connecting members one by one. The connecting member includes a first connecting rope and a connecting rod. Two ends of the first connecting rope are respectively connected to the mouth of the elastic bag and the connecting rod. The connecting rod is slidably connected to its corresponding fixing block. A wedge-shaped block is slidably connected to each fixing block. A clamping groove matching the wedge-shaped block is formed on the connecting rod. An elastic member is connected between the wedge-shaped block and the fixing block.

[0010] Furthermore, a toothed rotating ring is rotatably connected to the right connecting plate. The wedge-shaped block is connected to the toothed rotating ring through a second connecting rope. A second motor is installed on the right connecting plate. A gear is fixedly connected to the output shaft of the second motor. The gear meshes with the teeth on the toothed rotating ring.

[0011] Furthermore, a push rod is connected to the right connecting plate.

[0012] The beneficial effects are as follows: Through the design of the cleaning mechanism, the dirt on the inner wall of the pipeline can be effectively removed, ensuring the fitting effect of the repair material. The design of the elastic bag and the locking and retracting mechanism can effectively protect the repair material and conveniently release the protection when needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] Please refer to Figures 1-4 , a green environmental protection type water supply and drainage pipeline repair device, including two connecting plates 1. An airbag 2 is arranged between the two connecting plates 1. A repair material 10 is wrapped on the surface of the airbag 2. A cleaning mechanism 3 is installed on the left connecting plate 1. The cleaning mechanism 3 is used to clean the dirt on the inner wall of the pipeline. An airbag 4 is installed on the right side of the right connecting plate 1. The airbag 4 is used to discharge the dirt after expansion. A push rod 9 is connected to the right connecting plate 1. The push rod 9 facilitates the movement of the device body. An elastic bag 5 is sleeved outside the airbag 2. The elastic bag 5 is used to enclose and protect the repair material 10. The left end of the elastic bag 5 is fixedly connected to the left connecting plate 1. The right end of the elastic bag 5 is provided with a bag opening. Three connecting pieces 6 are circumferentially arranged at intervals around the bag opening of the elastic bag 5. A locking and retracting mechanism 7 is arranged on the right connecting plate 1. The locking and retracting mechanism 7 cooperates with the connecting piece 6 to keep the bag opening of the elastic bag 5 fixed at the right end of the airbag 2. When the locking and retracting mechanism 7 releases the fixation of the bag opening of the elastic bag 5, the elastic force of the elastic bag 5 is sufficient to move its bag opening completely to the left end of the airbag 2.

[0020] The cleaning mechanism 3 includes a cleaning rod 301 and a motor 302. A motor 302 is installed on the left connecting plate 1. The output shaft of the motor is fixedly connected with a mounting block 303. Two cleaning rods 301 are circumferentially installed on the mounting block 303. Three rollers 8 are circumferentially arranged at intervals on both connecting plates 1. The rollers 8 are connected to the connecting plates 1 through telescopic rods. The cleaning rod 301 is connected to the mounting block 303 through a telescopic rod. The telescopic rods on the rollers 8 and the cleaning rod 301 are designed so that the device body can adapt to pipelines with different diameters.

[0021] The locking and retracting mechanism 7 includes three fixing blocks 701. The three fixing blocks 701 are circumferentially and fixedly connected to the right connecting plate 1. The fixing blocks 701 correspond to the connecting pieces 6 one by one. The connecting piece 6 includes a connecting rope 601 and a connecting rod 602. The two ends of the connecting rope 601 are respectively connected to the bag opening of the elastic bag 5 and the connecting rod 602. The connecting rod 602 is slidably connected to its corresponding fixing block 701. A wedge-shaped clamping block 702 is slidably connected to each fixing block 701. A clamping groove 603 matching the wedge-shaped clamping block 702 is opened on the connecting rod 602. An elastic member 703 is connected between the wedge-shaped clamping block 702 and the fixing block 701. A toothed rotating ring 704 is rotatably connected to the right connecting plate 1. The wedge-shaped clamping block 702 is connected to the toothed rotating ring 704 through a connecting rope 707. A motor 705 is installed on the right connecting plate 1. A gear 706 is fixedly connected to the output shaft of the motor 705. The gear 706 meshes with the teeth on the toothed rotating ring 704.

[0022] Working principle: Initially, both airbag 2 and airbag 4 are in their natural states. The repair material 10 is wrapped around the surface of airbag 2. The mouth of the elastic bag 5 is fixed to the right end of airbag 2 through the cooperation of the connecting member 6 and the locking and pushing mechanism, so that the elastic band forms a closed protection for the repair material 10. Specifically, the connecting rod 602 is inserted into the fixing block 701, and the wedge-shaped clamping block 702 is snapped into the card slot 603 of the connecting rod 602 under the elastic action of the elastic member 703, so as to maintain the stable connection between the connecting rod 602 and the first connecting rope 601 and the fixing block 701, and further maintain the mouth of the elastic bag 5 fixed to the right end of airbag 2.

[0023] During use, the device body is pushed into the pipeline to be repaired through the push rod 9. When the device body enters the area to be repaired in the pipeline, while continuing to push the device body forward, the cleaning rod 301 is driven to rotate by the first motor 302 to clean the inner wall of the pipeline. The impurities after cleaning naturally fall to the bottom. During this process, the elastic bag 5 can protect the repair material 10 from being contaminated by the dirt cleaned off. When the cleaning of the area to be repaired is completed, the device body is continuously pushed forward until the airbag 4 is at the end of the cleaning area, and then the airbag 4 is inflated so that the airbag 4 expands to fit the inner wall of the pipeline. Then, the device body is pulled backward, so that the airbag 4 discharges the dirt after cleaning to the beginning of the cleaning area. At this time, the dirt in the cleaning area has been all processed. Then, the second motor 705 is used to drive the gear 706 to rotate. Under the meshing action of the gear 706 and the teeth on the toothed rotating ring 704, the toothed rotating ring 704 rotates, so as to pull the wedge-shaped clamping block 702 through the second connecting rope 707, making it disengage from the card slot 603 of the connecting rod 602, and further releasing the fixation of the mouth of the elastic bag 5. At this time, the mouth of the elastic bag 5 will completely move to the left end of the airbag 2 under its own elastic force, releasing the closed protection of the repair material 10. The elastic member 703 provides a restoring force for the wedge-shaped clamping block 702. Finally, the airbag 2 is inflated so that the repair material 10 expands to contact the pipeline for repair. After the repair is completed, the airbag 2 and the airbag 4 are restored to their original states, and the device body is removed from the pipeline through the push rod 9.
