Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, and more specifically, to an automatic repair device for leaks in raw water supply pipelines. Background Technology

[0002] An automatic repair device for leaks in raw water supply pipelines is a specialized device that automates the entire process of sealing leaks (cracks, pinholes, loose joints, etc.) caused by corrosion, aging, or external damage to raw water supply pipelines.

[0003] A search revealed that Chinese patent CN217559360U discloses a "Natural Gas Pipeline Leak Repair Device," which includes a leak repair mounting frame. The mounting frame contains a lifting assembly, and an adjustable pipe fixing assembly is located on one side of the lifting assembly. The adjustable pipe fixing assembly contains a surrounding repair assembly. Furthermore, to achieve the purpose of adjusting and fixing the pipe, the adjustable pipe fixing assembly includes two fixing rings. This invention improves upon existing technology. In practical use, it not only features a novel design and ingenious structure, utilizing polymer repair materials for pipe repair, and convenient adjustment of the repair head position, allowing for repair at any position on the pipe, but it can also fix natural gas pipelines of different diameters, greatly improving its applicability and overcoming the limitations of existing technology. However, the following drawbacks still exist:

[0004] (1) If there are impurities on the outer wall of the pipe, the sealant will not adhere properly. If air is mixed in when the sealant is sprayed, or if the small pits and rust holes on the outer wall of the pipe are not fully filled, air bubbles or gaps will be formed. These gaps will become channels for water to seep in later, resulting in no leakage at first, but leakage caused by impurities falling off later.

[0005] (2) When repair materials are stored in the liquid storage tank for a long time, they are prone to deposit at the bottom of the tank due to density difference, forming a hard sediment layer. To address this, an automatic repair device for leaks in raw water supply pipelines is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that if impurities are present on the outer wall of a pipe, the sealant will not adhere properly. If air is mixed in during the spraying of the sealant, or if the small pits and rust holes on the outer wall of the pipe are not fully filled, air bubbles or gaps will form. These gaps will become channels for water to seep in later, resulting in no leakage initially, but leakage caused by impurities falling off later.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: an automatic repair device for leaks in raw water supply pipelines, comprising a gantry frame and a pipeline. A drive slide rail is provided on the inner wall of the gantry frame, and a fixing rod is fixedly installed on the inner wall of the gantry frame. A repair device is provided at the output end of the drive slide rail. The repair device includes an electric push rod, the fixed end of which is fixedly installed at the output end of the drive slide rail. A rotating frame is fixedly installed at the output end of the electric push rod. A hollow frame is slidably installed on the inner wall of the rotating frame, and a nozzle assembly is provided on the inner wall of the hollow frame. A spring seat is provided between the hollow frame and the rotating frame. The rotating frame is moved by the extension of the output end of the electric push rod, which in turn moves the hollow frame, causing the nozzle assembly to contact the leak point and spray sealant.

[0009] As a preferred technical solution of this utility model, the repair device includes a fixing frame, which is fixedly installed on the inner wall of the fixing rod. An installation frame is fixedly installed on the top of the fixing frame, and a drive wheel is rotatably installed on the inner wall of the installation frame. By placing the pipe on the drive wheel, the electric push rod is driven by the drive slide rail, and the rotation of the drive wheel causes the pipe to rotate.

[0010] As a preferred technical solution of this utility model, the number of the fixing frame, mounting frame and drive wheel is set to two, and they are symmetrical to each other along the vertical central axis of the pipe. The number of the spring seats is set to two, and they are symmetrical to each other along the vertical central axis of the hollow frame.

[0011] As a preferred technical solution of this utility model, a connecting frame is rotatably installed on the outer wall of the hollow frame, and a cleaning roller is rotatably installed on the inner wall of the connecting frame. A torsion spring is provided between the connecting frame and the hollow frame. The cleaning roller preferentially contacts the outer wall of the pipe, so that impurities on the surface of the pipe are cleaned.

[0012] As a preferred technical solution of this utility model, a connecting frame two is rotatably installed on the outer wall of the hollow frame, and a laying plate is fixedly installed on the inner wall of the connecting frame two. A guide rod is fixedly installed on the surface of the laying plate near the pipe. Excess sealant will be guided outward with the setting of the guide rod. The material in the liquid storage tank is injected into the nozzle assembly in the hollow frame through the hose by the booster pump set at the bottom.

[0013] As a preferred technical solution of this utility model, an auxiliary device is provided on the circumferential surface of the electric push rod. The auxiliary device includes a liquid storage tank, which is fixedly installed on the fixed end of the electric push rod. A booster pump is provided at the bottom of the liquid storage tank. The booster pump is connected to the hollow frame through a hose. By adding repair material to the injection port, the output end of the servo motor drives the rotating rod to rotate. The rotation of the rotating rod drives the spiral blade to rotate, and the rotation of the spiral blade mixes the material in the liquid storage tank.

[0014] As a preferred technical solution of this utility model, a fixed end of a servo motor is fixedly installed on the top of the liquid storage tank, a rotating rod is fixedly installed on the output end of the servo motor, a spiral blade is fixedly installed on the circumferential surface of the rotating rod, and an injection port is provided on the circumferential surface of the liquid storage tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The repair device is calibrated to the leak point in the pipeline. The nozzle assembly contacts the leak point and sprays sealant. With the spring seat, the spring force helps the sealing material to fully fill the leak gap, improving the long-term sealing effect. When rotating and repairing along the circumference of the pipeline, the cleaning roller first contacts the outer wall of the pipeline to clean the impurities on the pipeline surface, preventing the sealant from losing adhesion and causing the sealant layer to detach. After the nozzle assembly sprays, the sprayed area is leveled by a flat plate. The slight pressure of the flat plate squeezes the sealant and removes internal air bubbles. The pressure can push the sealant to penetrate deep into the crack and fill the internal gaps, avoiding surface sealing and internal leakage, achieving a complete seal inside and out. Excess sealant is guided outward by the guide rod.

[0017] 2. With the help of the auxiliary device, before repair, the repair material is added to the injection port. The rotating spiral blade mixes the material in the storage tank. When the repair material is stored in the storage tank for a long time, it is easy to deposit at the bottom of the tank due to density difference, forming a hard sediment layer. The spiral blade, whose radius gradually decreases upward, has the largest bottom radius and can spirally transport the material at the bottom of the tank upward, which can fully mix with the return material above, reducing sedimentation from the source. Even after the stirring stops, the gap between the bottom of the spiral blade and the bottom of the tank is very small, which can slightly adhere to the bottom of the tank, preventing the material from forming a static sedimentation zone at the bottom of the tank. When the stirring is started again, no additional stirring is required, and the material at the bottom of the tank can be quickly circulated, reducing the load impact when the stirring is started, thereby protecting the servo motor.

[0028] like Figure 1 - Figure 5As shown, this embodiment proposes an automatic repair device for leaks in raw water supply pipelines, including a gantry frame 1 and a pipeline 2. A drive slide rail 3 is provided on the inner wall of the gantry frame 1, and a fixing rod 4 is fixedly installed on the inner wall of the gantry frame 1. A repair device 5 is provided at the output end of the drive slide rail 3. The repair device 5 includes an electric push rod 53.

A hollow frame 55 is slidably installed on the inner wall of the rotating frame 54. A nozzle assembly 56 is provided on the inner wall of the hollow frame 55. A spring seat 57 is provided between the hollow frame 55 and the rotating frame 54. With the spring seat 57, the elastic force of the spring assists the sealing material to fully fill the leak gap, improving the long-term sealing effect.

[0029] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, the repair device 5 further includes a fixing frame 50, which is fixedly installed on the inner wall of the fixing rod 4. A mounting frame 51 is fixedly installed on the top of the fixing frame 50, and a drive wheel 52 is rotatably installed on the inner wall of the mounting frame 51. The electric push rod 53 is driven by the drive slide rail 3, and the rotation of the drive wheel 52 causes the pipe 2 to rotate.

[0030] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, the number of fixing brackets 50, mounting brackets 51 and drive wheels 52 is set to two, and they are symmetrical to each other along the vertical central axis of the pipe 2. The number of spring seats 57 is set to two, and they are symmetrical to each other along the vertical central axis of the hollow frame 55.

[0031] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, a connecting frame 58 is rotatably installed on the outer wall of the hollow frame 55, and a cleaning roller 59 is rotatably installed on the inner wall of the connecting frame 58. A torsion spring is provided between the connecting frame 58 and the hollow frame 55, so that impurities on the surface of the pipe 2 are cleaned, preventing the adhesion of the sealant from being reduced and causing the sealing layer to delaminate and fail.

[0032] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, a connecting frame 2 510 is rotatably installed on the outer wall of the hollow frame 55, and a laying plate 511 is fixedly installed on the inner wall of the connecting frame 2 510. A guide rod 512 is fixedly installed on the surface of the laying plate 511 near the pipe 2. The slight pressure of the laying plate 511 will squeeze the adhesive and expel the internal air bubbles. The pressure can push the adhesive to penetrate into the depth of the crack and fill the internal gap of the crack, avoiding the situation of surface sealing and internal leakage.

[0033] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, an auxiliary device 6 is further provided on the circumferential surface of the electric push rod 53. The auxiliary device 6 includes a liquid storage tank 60, which is fixedly installed on the fixed end of the electric push rod 53. A booster pump 61 is provided at the bottom of the liquid storage tank 60. The booster pump 61 is connected to the hollow frame 55 through a hose 62. The booster pump 61 at the bottom allows the material in the liquid storage tank 60 to be injected into the nozzle assembly 56 in the hollow frame 55 through the hose 62.

[0034] like Figure 1 - Figure 5 As shown, in a preferred embodiment, based on the above method, the top of the liquid storage tank 60 is further provided with a fixed end of a servo motor 63, the output end of the servo motor 63 is fixedly mounted with a rotating rod 64, a spiral blade 65 is fixedly mounted on the circumferential surface of the rotating rod 64, and an injection port 66 is provided on the circumferential surface of the liquid storage tank 60. The spiral blade 65, whose radius gradually decreases upward, has the largest bottom radius and can spirally transport the bottom material upward, fully mix it with the return material above, and reduce the generation of sediment from the source.

[0035] Specifically, when using the automatic repair device for leaks in the raw water supply pipeline: the pipeline 2 is placed on the drive wheel 52, and the electric push rod 53 is driven by the drive slide rail 3. The rotation of the drive wheel 52 causes the pipeline 2 to rotate, aligning the repair device 5 with the leak point. The output end of the electric push rod 53 extends and drives the rotating frame 54 to move. The movement of the rotating frame 54 drives the hollow frame 55 to move, so that the nozzle assembly 56 contacts the leak point and sprays sealant. With the spring seat 57 in place, the spring force assists the sealing material in fully filling the leak gap, improving the long-term sealing effect. When the circumferential surface of pipe 2 is rotated for repair, the cleaning roller 59 first contacts the outer wall of pipe 2 to clean the impurities on the surface of pipe 2, preventing the sealant from losing adhesion and causing the sealant layer to detach and fail. After the nozzle group 56 sprays, the sprayed area is leveled by the spreading plate 511. The slight pressure of the spreading plate 511 will squeeze the adhesive and expel internal air bubbles. The pressure can push the adhesive to penetrate into the crack and fill the internal gaps, avoiding the situation of surface sealing and internal leakage, and achieving a seal that is integrated inside and out. Excess sealant will be guided outward by the setting of the guide rod 512.

[0036] Before repair, repair material is added to the injection port 66. The output of the servo motor 63 drives the rotating rod 64 to rotate. The rotation of the rotating rod 64 drives the spiral blade 65 to rotate. The rotation of the spiral blade 65 mixes the material in the storage tank 60. When the repair material is stored in the storage tank 60 for a long time, it is easy to deposit at the bottom of the tank due to density difference, forming a hard sediment layer. The spiral blade 65, whose radius gradually decreases upward, has the largest bottom radius and can spirally transport the material at the bottom of the tank upward, fully mixing it with the return material above, reducing sedimentation from the source. Even after the stirring stops, the gap between the bottom of the spiral blade 65 and the bottom of the tank is very small, so it can slightly adhere to the bottom of the tank, preventing the material from forming a static sedimentation zone at the bottom of the tank. When the stirring is started again, no additional stirring is required, and the material at the bottom of the tank can be quickly circulated, reducing the load impact when the stirring is started, thereby protecting the servo motor 63. The booster pump 61 set at the bottom injects the material in the storage tank 60 into the nozzle group 56 in the hollow frame 55 through the hose 62.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
