Description

Technical Field

[0001] This utility model specifically relates to a rapid sealing device for water pipelines, belonging to the technical field of water pipeline sealing mechanisms. Background Technology

[0002] Water pipelines are a core component of modern water conservancy projects and urban infrastructure, undertaking the crucial task of transporting water resources from the source to users. They are known as underground lifelines. Through a systematic pipeline network layout, they realize long-distance transportation, regional allocation, and terminal supply of water resources. Pipe jacking is a type of water pipeline. During construction and maintenance, it is necessary to seal the inside of the jacking pipe. For example, the pipe end sealing device mentioned in the authorization announcement number CN214999381U includes an air pipe. The air pipe is a hollow, sealed circular tube, and a sealing device is installed on the surface of the air pipe.

[0003] However, existing technologies still have the following problems:

[0004] This sealing device uses an air nozzle to inflate the support airbag for assisted sealing. However, in actual application, it requires external tools, making it difficult to complete the sealing operation quickly and conveniently, which hinders its widespread use. Furthermore, dirt and impurities on the inner wall of the pipeline will cause severe friction with the insertion plate and contact soft layer during the insertion and removal of the sealing device, accelerating the wear of the insertion plate and contact soft layer, making cleaning difficult. This not only shortens the service life of the sealing device and increases the cost of use, but may also lead to a decrease in sealing performance due to wear, making it impossible to effectively seal the pipeline.

[0005] To address the aforementioned problems, the inventors have proposed a rapid sealing device for water pipelines. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a rapid sealing device for water pipelines, which better solves the problems of the difficulty in conveniently cleaning the inner wall of the pipeline and the difficulty in quickly performing the sealing operation.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a rapid sealing device for water supply pipelines, comprising an insertion disc, a contact soft layer fixedly connected to the outer surface of the insertion disc, a rotating rod movably connected to the top surface of the insertion disc via a bearing, a follower disc fixedly connected to the outer surface of one end of the rotating rod, a brush layer fixedly connected to the outer surface of the follower disc, a limiting mechanism provided on the outer side of the rotating rod, the limiting mechanism comprising a limiting box fixedly connected to the outer surface of the rotating rod, a movable plate slidably connected to the inner cavity of the limiting box, a limiting rod fixedly connected to the top surface of the movable plate, a limiting spring provided in the inner cavity of the limiting box, a support mechanism provided at the end of the rotating rod away from the follower disc, an inflation mechanism provided on the top surface of the insertion disc, the inflation mechanism comprising an inflation tube fixedly connected to the top surface of the insertion disc, a pressing airbag fixedly connected to the top end of the inflation tube, and a one-way valve fixedly connected to the top end of the pressing airbag.

[0008] Preferably, in order to better pull the insertion disk, a pull handle is fixedly connected to the top surface of the insertion disk, and the outer diameter of the insertion disk is larger than the outer diameter of the follower disk.

[0009] Preferably, in order to better pull the limiting rod by the pull ring, the top end of the limiting rod is fixedly connected to the pull ring, and the end of the limiting rod away from the pull ring is movably connected to the limiting box.

[0010] Preferably, in order to better limit the position of the rotating rod, a limiting hole is provided on the top surface of the insertion disk, the limiting hole is matched with the structural size of the limiting rod, and the bottom surface of the limiting box is slidably connected to the insertion disk.

[0011] Preferably, in order to ensure that the limiting spring is compressed when the moving plate moves, one end of the limiting spring is fixedly connected to the moving plate, and the other end of the limiting spring away from the moving plate is fixedly connected to the limiting box.

[0012] Preferably, in order to better define the position of the sealing device, the support mechanism includes a sleeve box that is movably connected to the outer surface of the rotating rod, a receiving tube that is fixedly connected to the outer surface of the sleeve box, a telescopic rod that is threaded to the inner surface of the receiving tube, and a contact plate that is movably connected to one end of the telescopic rod via a bearing.

[0013] Preferably, in order to better define the position of the support mechanism, a clamping screw is threaded through the outer surface of the sleeve box, and a threaded hole matching the structural size of the clamping screw is opened at the top of the rotating rod, and a rotating rod is fixedly connected to the outer surface of the clamping screw.

[0014] Preferably, in order to better deflate, an exhaust pipe is fixedly connected to the outer surface of the inflation pipe, and a switch valve is provided on the outer side of the exhaust pipe.

[0015] The beneficial effects of this utility model are:

[0016] By incorporating a rotating rod, a follower disc, a brush layer, and a limiting mechanism, when cleaning the inner wall of the pipe is required, rotating the rotating rod causes the follower disc to rotate, which in turn causes the brush layer to rotate, thus scrubbing the inner wall of the pipe and removing dirt and impurities. This avoids wear between the insertion disc used for sealing and the contact soft layer, extending the service life of the sealing device. Furthermore, the limiting mechanism effectively restricts the rotation of the rotating rod. When the rotating rod is not needed, inserting the limiting rod into the limiting hole fixes its position, preventing it from rotating arbitrarily in non-operating conditions and ensuring the stability and safety of the device.

[0017] By incorporating a contact soft layer and an inflation mechanism, rapid sealing can be achieved. A pressure bladder is fixedly connected to the top of the inflation tube, and a one-way valve is fixedly connected to the top of the pressure bladder. By simply squeezing and pressing the pressure bladder multiple times, the contact soft layer can be made to fit more tightly against the inner wall of the pipe through the inflation tube, achieving rapid sealing. The operation is simple and convenient, saving time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, a rapid sealing device for water supply pipelines includes an insertion plate 1. A pull handle 9 is fixedly connected to the top surface of the insertion plate 1. The outer diameter of the insertion plate 1 is larger than the outer diameter of the follower plate 4. The operator holds the pull handle 9 on the top of the insertion plate 1 and can easily move the sealing device to the position where sealing is required. A contact soft layer 2, which is made of rubber, is embedded and fixedly connected to the outer surface of the insertion plate 1. A rotating rod 3 is movably connected to the top surface of the insertion plate 1 through a bearing. A follower plate 4 is fixedly connected to the outer surface of one end of the rotating rod 3. A brush layer 5 is fixedly connected to the outer surface of the follower plate 4. As the rotating rod 3 rotates, the follower plate 4 drives the brush layer 5 to rotate, brushing and cleaning the inner wall of the water supply pipeline to remove dirt, impurities, etc.

[0025] A limiting mechanism 6 is provided on the outer side of the rotating rod 3. The limiting mechanism 6 includes a limiting box 61 fixedly connected to the outer surface of the rotating rod 3. A movable plate 62 is slidably connected to the inner cavity of the limiting box 61. A limiting rod 63 is fixedly connected through the top surface of the movable plate 62. A limiting hole 10 is opened on the top surface of the insertion plate 1. The limiting hole 10 matches the structural dimensions of the limiting rod 63. The bottom surface of the limiting box 61 is slidably connected to the insertion plate 1. A pull ring 65 is fixedly connected to the top of the limiting rod 63. The end of the limiting rod 63 away from the pull ring 65 is movably connected through the limiting box 61. A limiting spring 64 is provided in the inner cavity of the limiting box 61. The limit rod 63 is fixedly connected to the movable plate 62 at one end, and the limit spring 64 is fixedly connected to the limit box 61 at the other end away from the movable plate 62. The operator hooks the pull ring 65 at the top of the limit rod 63 with his finger and pulls the limit rod 63 upward. Since the limit rod 63 is fixedly connected to the movable plate 62 in the inner cavity of the limit box 61, and the limit box 61 is equipped with a limit spring 64, one end of the limit spring 64 is fixedly connected to the movable plate 62, and the other end is fixedly connected to the limit box 61, pulling the limit rod 63 will cause the movable plate 62 to slide upward in the limit box 61, compressing the limit spring 64. At this time, the limit spring 64 deforms and generates elastic force.

[0026] A support mechanism 7 is provided at the end of the rotating rod 3 away from the follower disk 4. The support mechanism 7 includes a sleeve box 71 that is movably connected to the outer surface of the rotating rod 3. A clamping screw 75 is threadedly connected to the outer surface of the sleeve box 71. The top of the rotating rod 3 has a threaded hole that matches the structural dimensions of the clamping screw 75. The rotating rod 3 is fixedly connected to the outer surface of the clamping screw 75. The sleeve box 71 of the support mechanism 7 is movably connected to the outer surface of the rotating rod 3. The operator first rotates the clamping screw 75, which is threadedly connected to the outer surface of the sleeve box 71, so that the clamping screw 75... Unscrew the sleeve box 71 from the threaded hole at the top of the rotating rod 3 that matches the structural dimensions of the clamping screw 75. Install the sleeve box 71 on the outer surface of the rotating rod 3. The outer surface of the sleeve box 71 is fixedly connected to the receiving tube 72. The inner surface of the receiving tube 72 is threadedly connected to the telescopic rod 73. One end of the telescopic rod 73 is movably connected to the contact plate 74 through the bearing. Then rotate the telescopic rod 73 threadedly connected to the inner surface of the receiving tube 72 to adjust the length of the telescopic rod 73 so that one end of the telescopic rod 73, which is movably connected to the contact plate 74 through the bearing, contacts the inner wall of the pipe to provide support for the device.

[0027] An inflation mechanism 8 is provided on the top surface of the insertion plate 1. The inflation mechanism 8 includes an inflation tube 81 that is fixedly connected to the top surface of the insertion plate 1. The inflation tube 81 is in communication with the contact soft layer 2. An exhaust pipe 84 is fixedly connected to the outer surface of the inflation tube 81. A switch valve is provided on the outer side of the exhaust pipe 84. When the operator opens the switch valve on the outer side of the exhaust pipe 84, the gas between the insertion plate 1 and the inner wall of the pipe is discharged from the exhaust pipe 84, and the contact soft layer 2 is separated from the inner wall of the pipe. A pressing airbag 82 is fixedly connected to the top of the inflation tube 81. When the operator squeezes the pressing airbag 82 fixedly connected to the top of the inflation tube 81 in the inflation mechanism 8 on the top surface of the insertion plate 1 multiple times, air enters the pressing airbag 82 through the one-way valve 83, and then enters the space between the insertion plate 1 and the inner wall of the pipe through the inflation tube 81, thereby causing the contact soft layer 2 to expand and adhere to the pipe wall. The one-way valve 83 is fixedly connected to the top of the pressing airbag 82.

[0028] Working principle: When in use, the operator holds the pull handle 9 fixedly connected to the top surface of the insertion plate 1 and uses the pull handle 9 to easily move the entire water pipeline quick sealing device to the position of the water pipeline that needs to be sealed.

[0029] Furthermore, the operator hooks the pull ring 65 at the top of the limiting rod 63 with their finger and pulls the limiting rod 63 upward. Pulling the limiting rod 63 will cause the moving plate 62 to slide upward in the limiting box 61, compressing the limiting spring 64. At this time, the limiting spring 64 deforms and generates elastic force. At the same time, the end of the limiting rod 63 away from the pull ring 65 is pulled out from the limiting hole 10 on the top surface of the insertion plate 1, which matches the structural size of the limiting rod 63, thus releasing the rotation restriction on the rotating rod 3.

[0030] Furthermore, the operator rotates the rotating rod 3, which is movably connected through the bearing on the top surface of the insertion disc 1. A follower disc 4 is fixedly connected to the outer surface of one end of the rotating rod 3, and a brush layer 5 is fixedly connected to the outer surface of the follower disc 4. As the rotating rod 3 rotates, the follower disc 4 drives the brush layer 5 to rotate, brushing and cleaning the inner wall of the water supply pipe. At this time, the insertion disc 1 assembly is inserted into the pipe.

[0031] Furthermore, after cleaning, the operator releases the pull ring 65. Under the elastic force of the limit spring 64, the moving plate 62 slides downward in the limit box 61, driving the limit rod 63 to move downward, so that the limit rod 63 is re-inserted into the limit hole 10, fixing the position of the rotating rod 3 and preventing it from rotating arbitrarily in the non-operational state, thus ensuring the stability and safety of the device.

[0032] Furthermore, the sleeve box 71 of the support mechanism 7 is movably connected to the outer surface of the rotating rod 3. The operator rotates the clamping screw 75 so that one end of it is screwed into the threaded hole at the top of the rotating rod 3, thus fixing the sleeve box 71 on the rotating rod 3.

[0033] Furthermore, the operator rotates the telescopic rod 73, which is threadedly connected to the inner surface of the storage tube 72 fixedly connected to the outer surface of the sleeve box 71, and adjusts the length of the telescopic rod 73 so that one end of the telescopic rod 73 contacts the inner wall of the pipe through the contact plate 74 movably connected by the bearing, thereby providing support for the device.

[0034] Furthermore, the operator repeatedly squeezes the pressure airbag 82 fixedly connected to the top end of the inflation tube 81 in the inflation mechanism 8 on the top surface of the insertion plate 1. Since the top end of the pressure airbag 82 is fixedly connected to the one-way valve 83, air enters the pressure airbag 82 through the one-way valve 83, and then enters the space between the insertion plate 1 and the inner wall of the pipe through the inflation tube 81, thereby causing the contact soft layer 2 to expand and fit more tightly against the pipe wall, achieving rapid sealing.

[0035] Furthermore, when it is necessary to remove the seal, the operator opens the switch valve on the outside of the exhaust pipe 84, which is fixedly connected to the outer surface of the air inflator 81, so that the gas between the insertion disc 1 and the inner wall of the pipe is discharged from the exhaust pipe 84, the contact soft layer 2 is separated from the inner wall of the pipe, and then the operator pulls the insertion disc 1 out of the water supply pipe by pulling the handle 9.
