Description

Technical Field

[0001] This utility model relates to the field of pipeline leak prevention technology, and more specifically, it relates to a pipeline leak prevention device. Background Technology

[0002] Pipes, as one of the common items in municipal and housing construction, are used to transport and discharge water. After long-term use, pipes will age and corrode, causing cracks in the outer wall of the pipe, which will lead to water seeping out of the pipe. At this time, workers will use leak-proof devices to seal the cracks in the pipe and extend the service life of the pipe.

[0003] Publication number CN219389016U discloses a pipe leak-proof device, the technical solution of which includes an installation plate, a fixing plate fixedly connected to the bottom of the installation plate, an anti-slip pad adhered to the bottom of the fixing plate, a pipe provided at the bottom of the fixing plate, a tightening device installed at the top of the installation plate, a leak-proof device provided at the bottom of the pipe, the tightening device including a movable plate, four connecting rods inserted through the top of the movable plate, a limit block fixedly connected to one end of the four connecting rods, a threaded rod threadedly connected through the top of the movable plate, a rotating disk fixedly connected to one end of the threaded rod, and slots opened on both sides of the movable plate.

[0004] The above technical solution, when sealing the crack in the pipeline, involves inserting the two ends of two steel wire ropes into the slots and rotating the threaded rod to gradually raise the moving plate. At the same time, the moving plate drives the two steel wire ropes to move upward, so that the sealing rubber layer on the clamp plate comes into contact with the crack in the pipeline, preventing the crack from coming into contact with the outside, thereby preventing water in the pipeline from seeping out through the crack and improving the service life of the pipeline.

[0005] However, when the above technical solution is used to seal pipes of different diameters, the clamp does not have the ability to deform. Therefore, when the sealing rubber layer on the clamp comes into contact with the surface of the pipe of different diameters, it will be difficult for the sealing rubber layer on the clamp to adhere to the surface of the pipe of different diameters. This will reduce the sealing performance between the sealing rubber layer and the pipe surface and affect the anti-leakage effect of the pipe.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pipeline leak prevention device, which solves the problem that when sealing pipelines of different diameters, the sealing rubber layer is difficult to adhere to the surface of the pipeline of different diameters, which reduces the sealing performance between the sealing rubber layer and the pipeline surface and affects the leak prevention effect of the pipeline.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe leak-proof device, including a sealing layer and a base, a fixing plate fixedly connected to the base, a flexible sheet one detachably connected to the side wall of the fixing plate, a cavity formed between the flexible sheet one and the fixing plate, a flexible sheet two fixedly connected to the flexible sheet one in the cavity, the side of the flexible sheet one and the flexible sheet two away from the base and the fixing plate being fixedly connected to the sealing layer, an adjustment component for adjusting the size of the cavity provided on the fixing plate, a movable plate slidably connected to the base, and a driving component for driving the movable plate to move along the side wall of the base.

[0009] By adopting the above structural configuration, when sealing the pipe surface, flexible sheet one and fixed plate are installed together, and the pipe is placed in the cavity formed between flexible sheet one and flexible sheet two. Then, the driving assembly drives the moving plate towards flexible sheet one. When the moving plate contacts one side wall of the flexible sheet, it continues to move in the same direction, causing flexible sheet one to deform. At this time, the pipe in the cavity is pushed by the flexible sheet one and moves towards flexible sheet two. When the pipe moves to abut against the sealing layer on flexible sheet two, the sealing layer on flexible sheet one... The sealing layer also abuts against the pipe. At this time, the pipe is restricted by the moving plate and the fixed plate, fixing the pipe between the moving plate and the fixed plate, thereby achieving the effect of fixing the pipe. After fixing the pipe, the size of the cavity is adjusted by the adjustment component to match the size of the pipe diameter, so that the sealing layer on the flexible sheet fits against the pipe surface, thereby completing the sealing effect of the pipe surface. By adjusting the component, the sealing performance between the sealing layer and the pipe surface can be increased, improving the leak-proof effect of the pipe and increasing the service life of the pipe.

[0010] The present invention is further configured such that: two mounting grooves are provided on the fixed plate for the flexible sheet to slide, and limit plates are fixedly connected to both sides of the flexible sheet.

[0011] By using the aforementioned limiting plate, when it is necessary to install the flexible sheet one and the fixed plate together, the flexible sheet one is inserted into one of the mounting slots, and one of the limiting plates and the side wall of the fixed plate come into contact with each other. Then, the flexible sheet one is deformed and bent to form a cavity between the flexible sheet one and the flexible sheet two, and then inserted into the other mounting slot. At this time, the flexible sheet one is restricted by the mounting slot and the limiting plate, so that the flexible sheet one cannot deform and recover, thereby achieving the effect of installing the flexible sheet one and the fixed plate together.

[0012] The present invention is further configured such that: the adjustment assembly includes an adjustment plate, the side wall of the adjustment plate has a through groove for sliding of a flexible sheet, and a plurality of screws are threadedly connected to the side wall of the adjustment plate, the screws passing through the adjustment plate and rotatably connected to the side wall of the fixed plate.

[0013] By using the above-mentioned adjustment components, when the size of the cavity needs to be adjusted, the flexible sheet is inserted into the through slot, and the limiting plate and the adjusting plate are brought into contact. Then, the screw is driven to rotate. The adjusting plate, affected by the screw, begins to move away from the fixed plate, causing the flexible sheet to move in the same direction. At this time, the flexible sheet located in the cavity is affected and begins to deform, causing the cavity to shrink. When it is necessary to enlarge the cavity, simply rotate the screw in the opposite direction to drive the adjusting plate towards the fixed plate. At this time, the flexible sheet deforms and recovers, enlarging the cavity space, thereby achieving the effect of adjusting the size of the space inside the cavity.

[0014] The present invention is further configured such that: a limiting groove is provided on the side wall of the fixing plate, a limiting ring is rotatably connected in the limiting groove, and the screw is fixedly connected to the inner wall of the limiting ring.

[0015] By using the aforementioned limiting ring, it is possible to prevent the screw from separating from the fixed plate during rotation, thus avoiding affecting the normal use of the adjusting plate.

[0016] The present invention is further configured such that: the driving component includes a moving block fixedly connected to the bottom of the moving plate; the base has a sliding groove for the moving block to slide; and a second screw is rotatably connected to the side wall of the base, the second screw passing through the base and the moving block and being threadedly connected to the moving block.

[0017] By adopting the above-mentioned drive component configuration, when the moving plate is driven to move, the second drive screw rotates, and the moving block is affected by the screw, causing the moving plate to move along the slide groove, thereby achieving the effect of driving the moving plate to move.

[0018] The present invention is further configured such that the flexible sheet two and the fixed plate are connected by a number of springs.

[0019] By using the above-mentioned spring configuration, when the pipe and the second flexible sheet come into contact with each other, several springs will be affected and deformed and compressed. At this time, the springs will release elastic potential energy, causing the second flexible sheet to deform, further making the second flexible sheet and the side wall of the pipe fit together, thus improving the sealing effect of the second flexible sheet on the pipe surface.

[0020] The present invention is further configured such that: two slide rails are fixedly connected to the side of the fixing plate near the mounting groove, a limiting plate is slidably connected between the two slide rails, and the through groove passes through the two slide rails.

[0021] By adopting the above-mentioned slide rail configuration, the stability between the flexible sheet and the mounting groove can be improved, and separation between the flexible sheet and the mounting groove can be avoided.

[0022] In summary, this utility model has the following beneficial effects: When sealing the surface of a pipe, the pipe is placed between flexible sheet one and flexible sheet two to form a cavity. Then, the driving component drives the pipe to abut against the sealing layers on the moving plate and the fixed plate respectively. The size of the cavity is then adjusted by the adjusting component to match the diameter of the pipe, thereby making the sealing layer on flexible sheet one fit against the pipe surface, thus achieving the effect of sealing the pipe surface. By adjusting the component, the sealing performance between the sealing layer and the pipe surface can be increased, improving the leak-proof effect of the pipe and increasing the service life of the pipe.

[0030] A pipe leak prevention device, such as Figures 1-3 As shown, the system includes a sealing layer 1 and a base 2. A fixing plate 3 is fixedly connected to the base 2. A flexible sheet 4 is detachably connected to the side wall of the fixing plate 3, forming a cavity 5 between the flexible sheet 4 and the fixing plate 3. A flexible sheet 6 is fixedly connected to the flexible sheet 4 in the cavity 5. The side of the flexible sheet 4 and the flexible sheet 6 away from the base 2 and the fixing plate 3 is fixedly connected to the sealing layer 1. Both the flexible sheet 4 and the flexible sheet 6 can be made of galvanized iron sheet, which has good flexibility and moisture-proof effect, and can improve the service life of the flexible sheet 4 and the flexible sheet 6. The fixing plate 3 is provided with an adjustment component for adjusting the size of the cavity 5. A movable plate 7 is slidably connected to the base 2. The base 2 is provided with a drive component for driving the movable plate 7 to move along the side wall of the base 2. When sealing the pipe surface, the flexible sheet 4 and the fixing plate 3 are installed together, and the pipe is placed in the cavity 5 formed between the flexible sheet 4 and the flexible sheet 6. Then, the movable plate is driven by the drive component. 7 moves towards the flexible sheet 4. When the moving plate 7 and the side wall of the flexible sheet 4 come into contact with each other, the moving plate 7 continues to move in the same direction, causing the flexible sheet 4 to deform. At this time, the pipe in the cavity 5 is pushed by the flexible sheet 4 and moves towards the flexible sheet 6. When the pipe moves to abut against the sealing layer 1 on the flexible sheet 6, the sealing layer 1 on the flexible sheet 4 also abuts against the pipe. At this time, the pipe is restricted by the moving plate 7 and the fixed plate 3, fixing the pipe between the moving plate 7 and the fixed plate 3, thereby achieving the effect of fixing the pipe. After fixing the pipe, the size of the cavity 5 is adjusted by the adjusting component to match the diameter of the pipe, thereby making the sealing layer 1 on the flexible sheet 4 fit against the pipe surface, thus completing the effect of sealing the pipe surface. By adjusting the component, the sealing performance between the sealing layer 1 and the pipe surface can be increased, improving the leak-proof effect of the pipe and increasing the service life of the pipe.

[0031] like Figures 1-3As shown, the fixed plate 3 has two mounting grooves 8 for sliding of the flexible sheet 4. Limiting plates 9 are fixedly connected to both sides of the flexible sheet 4. When it is necessary to install the flexible sheet 4 and the fixed plate 3 together, the flexible sheet 4 is inserted into one of the mounting grooves 8, and one of the limiting plates 9 and the side wall of the fixed plate 3 are in contact with each other. Then the flexible sheet 4 is deformed and bent to form a cavity 5 between the flexible sheet 4 and the flexible sheet 6, and then inserted into the other mounting groove 8. At this time, the flexible sheet 4 is restricted by the mounting groove 8 and the limiting plate 9, so that the flexible sheet 4 cannot deform and recover, thereby achieving the effect of installing the flexible sheet 4 and the fixed plate 3 together.

[0032] like Figure 2 As shown, the adjustment assembly includes an adjustment plate 10. The side wall of the adjustment plate 10 has a through groove 11 for sliding the flexible sheet 4. Several screws 12 are threadedly connected to the side wall of the adjustment plate 10. The screws 12 pass through the adjustment plate 10 and are rotatably connected to the side wall of the fixed plate 3. When the size of the cavity 5 needs to be adjusted, the flexible sheet 4 is inserted into the through groove 11, and the limiting plate 9 and the adjustment plate 10 are brought into contact. Then, the screws 12 are driven to rotate. Affected by the screws 12, the adjustment plate 10 begins to move away from the fixed plate 3, causing the flexible sheet 4 to move in the same direction. At this time, the flexible sheet 4 is located in the cavity. The flexible sheet 4 at point 5 is affected and begins to deform, causing the cavity 5 to shrink. When it is necessary to enlarge the cavity 5, simply rotate the screw 12 in the opposite direction to drive the adjusting plate 10 towards the fixed plate 3. At this time, the flexible sheet 4 deforms and recovers, and the cavity 5 is enlarged, thereby achieving the effect of adjusting the size of the space inside the cavity 5. A limiting groove 13 is opened on the side wall of the fixed plate 3, and a limiting ring 14 is rotatably connected in the limiting groove 13. The screw 12 and the inner wall of the limiting ring 14 are fixedly connected, which can prevent the screw 12 from separating from the fixed plate 3 when rotating, thus avoiding affecting the normal use of the adjusting plate 10.

[0033] like Figures 1-3 As shown, the driving assembly includes a movable block 15 fixedly connected to the bottom of the movable plate 7. A groove 16 is provided on the base 2 for the movable block 15 to slide. A screw 17 is rotatably connected to the side wall of the base 2. The screw 17 passes through the base 2 and the movable block 15 and is threadedly connected to the movable block 15. When the movable plate 7 is driven to move, the screw 17 is driven to rotate. At the same time, the movable block 15 is affected by the screw and drives the movable plate 7 to move along the groove 16, thereby achieving the effect of driving the movable plate 7 to move.

[0034] like Figure 2As shown, the flexible sheet 6 and the fixed plate 3 are connected by several springs 18. When the pipe and the flexible sheet 6 come into contact with each other, the springs 18 will be affected and deformed and compressed. At this time, the springs 18 will release elastic potential energy, causing the flexible sheet 6 to deform, further making the flexible sheet 6 and the side wall of the pipe fit together, thus improving the sealing effect of the flexible sheet 6 on the pipe surface.

[0035] like Figure 1 , Figure 3 As shown, two slide rails 19 are fixedly connected to the side of the fixed plate 3 near the mounting groove 8, and a limiting plate 20 is slidably connected between the two slide rails 19. The through groove 11 passes through the two slide rails 19, which can improve the stability between the flexible sheet 4 and the mounting groove 8 and prevent the flexible sheet 4 and the mounting groove 8 from separating.

[0036] The working principle of this utility model is as follows: When sealing the surface of a pipe, the flexible sheet 4 and the fixed plate 3 are installed together, and the pipe is placed in the cavity 5 formed between the flexible sheet 4 and the fixed plate 6. Then, the screw 17 is driven to rotate, and the moving block 15 is affected by the screw, causing the moving plate 7 to move along the slide groove 16. When the moving plate 7 and the side wall of the flexible sheet 4 come into contact with each other, the moving plate 7 continues to move in the same direction, causing the flexible sheet 4 to deform. At this time, the pipe in the cavity 5 is pushed by the flexible sheet 4 and moves towards the flexible sheet 6. When the pipe moves to abut against the sealing layer 1 on the flexible sheet 6, the sealing layer 1 on the flexible sheet 4 also abuts against the pipe. At this time, the pipe is restricted by the moving plate 7 and the fixed plate 3, so that the pipe is fixed to the moving plate 7 and the fixed plate 3. Between the fixed plates 3, the pipe is fixed. After the pipe is fixed, the flexible plate 4 is inserted into the through groove 11, and the limiting plate 9 and the adjusting plate 10 are brought into contact. Then, the screw 12 is driven to rotate. The adjusting plate 10 is affected by the screw 12 and begins to move away from the fixed plate 3, which drives the flexible plate 4 to move in the same direction. At this time, the flexible plate 4 located in the cavity 5 is affected and begins to deform, and the cavity 5 begins to shrink. When the size of the cavity 5 matches the diameter of the pipe, the sealing layer 1 on the flexible plate 4 is then attached to the pipe surface, thus sealing the pipe surface. By adjusting the components, the sealing between the sealing layer 1 and the pipe surface can be increased, the anti-leakage effect of the pipe can be improved, and the service life of the pipe can be increased.
