Description

Technical Field

[0001] This utility model relates to the field of water conservancy channel joint sealing technology, and in particular to an adjustable water conservancy channel joint sealing device. Background Technology

[0002] Mountain irrigation canals typically use circular pipes, primarily for transporting water to meet irrigation and drainage needs. During pipe splicing, joint sealing devices are usually used to seal the pipe joints, thereby preventing fluid leakage or external impurities from entering the pipe.

[0003] According to the search, the Chinese patent "A sealing device for water pipe splice joints" authorized announcement number "CN221943462U" uses a plug pipe and a water pipe cover pipe fixed on the outer surface of the plug pipe to cooperate with each other to make a double threaded connection of the water pipe, thereby achieving a simple installation method and a strong sealing effect.

[0004] In the aforementioned application, the flow of liquid in the connector and the water pipe will cause vibration at the connection between the connector and the water pipe, which may easily lead to loosening at the connection between the connector and the water pipe, thereby affecting the sealing effect of the pipe joint. Utility Model Content

[0005] Therefore, it is necessary to provide an adjustable sealing device for the joints of water conservancy channels to address the problem of loosening at the connection between the connector and the water pipe.

[0006] The system includes: a first pipe, a second pipe, bolts, and nuts; and a leak-proof mechanism. The leak-proof mechanism includes two semi-pressure rings that engage with the inner wall of the first pipe. Both ends of each semi-pressure ring are fixedly connected to annularly distributed limiting brackets. A sealing ring is slidably connected to the inner wall of the first pipe. The surface of the sealing ring engages with the inner wall of the second pipe. One end of the sealing ring is fixedly connected to a corrugated gasket, and the other end of the corrugated gasket is fixedly connected to one end of the inner wall of the first pipe. Through the cooperation of the bolts and nuts, the sealing rings are tightly engaged with the second pipe, thus sealing the connection between the first and second pipes. The cooperation of the semi-pressure rings and the limiting brackets locks the bolts and nuts in place, ensuring a tight connection between the first and second pipes and preventing the nuts from loosening, thus guaranteeing a good seal at the pipe joint.

[0007] In one embodiment, two pressure blocks are fixedly connected to the inner surface of the semi-pressure ring, and the ends of the pressure blocks contact the surface of the sealing ring. By pressing the sealing ring with the pressure blocks, it is ensured that the sealing ring fits tightly inside the second pipe, thereby ensuring the sealing effect at the connection between the first pipe and the second pipe.

[0008] In one embodiment, the inner wall of one of the semi-pressure rings is rotatably connected to two limiting rods, the surfaces of which are slidably connected to the inner wall of the other semi-pressure ring.

[0009] In one embodiment, a magnetic block is fixedly connected to the upper surface of the limiting rod.

[0010] In one embodiment, one of the semi-pressure rings is fixedly connected to the end of two magnetic rings, and the magnetic block and the magnetic rings are attracted to each other by opposite poles.

[0011] In one embodiment, a rubber block is slidably connected to the inner wall of the magnetic ring, and the surface of the rubber block is engaged with the upper end of the inner wall of the limiting rod. The interaction between the magnetic block and the magnetic ring restricts the rotation angle of the limiting rod, ensuring that the lower end of the limiting rod surface abuts against the end of one of the half-pressure rings. This ensures that the rubber block is precisely engaged within the limiting rod, thereby guaranteeing a stable connection between the two half-pressure rings and ensuring stable locking of the bolt and nut.

[0012] In one embodiment, the surface of the limiting rod is provided with two arc-shaped grooves.

[0013] In one embodiment, two arc-shaped pads are fixedly connected to the inner wall of one of the semi-pressure rings, and the surfaces of the arc-shaped pads are engaged with the inner wall of the arc-shaped groove. The interaction between the arc-shaped groove and the arc-shaped pads increases the resistance to the rotation of the limiting rod, thereby ensuring that the lower end of the surface of the limiting rod stably abuts against the end of one of the semi-pressure rings.

[0014] Beneficial effects

[0015] 1. By using bolts and nuts together, the sealing ring is tightly fitted into the second pipe, thereby sealing the connection between the first and second pipes. By using a semi-pressure ring and a limiting bracket together, the bolts and nuts are locked, ensuring a tight connection between the first and second pipes and preventing the nuts from loosening, thus ensuring the sealing effect at the pipe joint.

[0016] 2. The sealing ring is pressed by the pressure block, which ensures that the sealing ring fits tightly inside the second pipe, thereby ensuring the sealing effect at the connection between the first pipe and the second pipe. Attached Figure Description

[0029] The following is combined Figures 1-4 This invention describes an adjustable sealing device for joints in water conservancy channels.

[0030] In one embodiment, an adjustable water conservancy channel joint sealing device includes: a first pipe 100, a second pipe 200, a bolt 300, and a nut 400; a leak-proof mechanism 500, which includes two semi-pressure rings 501 that are snapped onto the inner wall of the first pipe 100. Both ends of the semi-pressure rings 501 are fixedly connected to a ring-shaped limiting frame 502. A sealing ring 504 is slidably connected to the inner wall of the first pipe 100. The surface of the sealing ring 504 is snapped onto the inner wall of the second pipe 200. One end of the sealing ring 504 is fixedly connected to a corrugated gasket 503, and the other end of the corrugated gasket 503 is fixedly connected to one end of the inner wall of the first pipe 100.

[0031] In this embodiment, when the pipe joint needs to be sealed, the end of the first pipe 100 is aligned and abutted with the end of the second pipe 200, so that the sealing ring 504 is snapped into the second pipe 200. Multiple bolts 300 are respectively inserted into the reserved holes on the first pipe 100 and the second pipe 200. An electric wrench is used to thread the nut 400 onto the surface of the bolt 300, thereby installing the first pipe 100 and the second pipe 200 together. Both half-pressure rings 501 are snapped into the first pipe 100 and the second pipe 200, so that the end of one of the limiting brackets 502 contacts one end of the bolt 300, and the end of the other limiting bracket 502 contacts one end of the nut 400, thereby making the first pipe 100 and the second pipe 200 tightly connected.

[0032] After connecting multiple pipe sections in the above manner, water can be pumped into the pipes to facilitate drainage.

[0033] like Figure 3 As shown, two pressure blocks 505 are fixedly connected to the inner surface of the semi-pressure ring 501, and the ends of the pressure blocks 505 contact the surface of the sealing ring 504.

[0034] like Figure 4 As shown, two limiting rods 506 are rotatably connected to the inner wall of one of the half-pressure rings 501. The surface of the limiting rod 506 is slidably connected to the inner wall of the other half-pressure ring 501. A magnetic block 507 is fixedly connected to the upper end of the surface of the limiting rod 506. Two magnetic rings 508 are fixedly connected to the end of one of the half-pressure rings 501. The magnetic block 507 and the magnetic ring 508 attract each other with opposite poles. A rubber block 509 is slidably connected to the inner wall of the magnetic ring 508. The surface of the rubber block 509 is engaged with the upper end of the inner wall of the limiting rod 506. Two arc-shaped grooves 511 are formed on the surface of the limiting rod 506. Two arc-shaped pads 510 are fixedly connected to the inner wall of one of the half-pressure rings 501. The surface of the arc-shaped pads 510 is engaged with the inner wall of the arc-shaped grooves 511. The sealing ring 504, the corrugated pad 503, the half-pressure ring 501, and the arc-shaped pads 510 are all rubber components.

[0035] In this embodiment, one end of the half-pressure ring 501 abuts against the end of the other half-pressure ring 501, causing the limiting rod 506 to slide into the other half-pressure ring 501. The magnetic block 507 is moved, causing its side to magnetically attract the side of the magnetic ring 508. The limiting rod 506 is rotated at an angle, causing the lower end of its surface to abut against the end of the other half-pressure ring 501. The surface of the arc-shaped pad 510 is engaged in the arc-shaped groove 511, and the rubber block 509 is pushed to move within the magnetic ring 508 and engage with the upper end of the inner wall of the limiting rod 506, thus installing the two half-pressure rings 501 together.

[0036] Working principle: Align the end of the first pipe 100 with the end of the second pipe 200, causing the sealing ring 504 to engage inside the second pipe 200. Insert multiple bolts 300 into the pre-drilled holes on the first pipe 100 and the second pipe 200 respectively, and thread them onto the nuts 400. Engage both half-pressure rings 501 into the first pipe 100 and the second pipe 200. Move the magnetic block 507, causing its side to magnetically attract the side of the magnetic ring 508. The lower end of the surface of the limiting rod 506 abuts against the end of the other half-pressure ring 501, causing the surface of the arc-shaped pad 510 to engage with the arc-shaped groove 511, pushing the rubber block 509 to engage with the upper end of the inner wall of the limiting rod 506, causing the end of one side of the limiting bracket 502 to contact one end of the bolt 300, and the end of the other side of the limiting bracket 502 to contact one end of the nut 400, causing the end of the pressure block 505 to abut against the surface of the sealing ring 504, thereby making the first pipe 100 and the second pipe 200 tightly connected.

[0037] It should be noted that the first pipe 100, the second pipe 200, the bolt 300, the nut 400, the magnetic block 507, and the magnetic ring 508 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
