[0009] Preferably, the anti-seepage cover is provided with a plurality of circumferential array threaded holes on the side close to the first pipeline, and the shank portions of the plurality of locking screws are threadedly connected with the anti-seepage cover through the threaded holes.

[0013] Compared with the prior art, the building engineering water supply and drainage pipe anti-seepage device has the following advantages and beneficial effects:

[0014] 1. The building engineering water supply and drainage pipe anti-seepage device is completely wrapped around the connection part of the first flange ring and the second flange ring through the cooperation of the anti-seepage shell and the anti-seepage cover. During installation, the sealing ring is first placed between the two flange rings, and then the bolt and the nut are fastened, and then the anti-seepage shell is slid to move the arc-shaped limiting groove along the arc-shaped limiting strip to completely cover the flange connection, and then the splicing pin of the anti-seepage cover is inserted into the splicing sleeve, and finally the locking screw is tightened to complete the assembly.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0024] like Figures 1 to 6As shown, a seepage prevention device for water supply and drainage pipes in building engineering includes a first pipe 1 and a second pipe 2 connected end to end. A first flange ring 3 is fixedly connected to one end of the first pipe, and a second flange ring 4 is fixedly connected to one end of the second pipe 2. A sealing ring 5 is provided between the second flange ring 4 and the first flange ring 3. A plurality of circumferentially arranged bolts 6 are rotatably connected to one side of the first flange ring 3. The threaded portion of each of the bolts 6 passes through the sealing ring 5 and is slidably connected to the second flange ring 4. A nut 7 is threadedly connected to the threaded portion of each bolt 6. A seepage prevention shell 8 is slidably connected to the outer surface of the first pipe 1, and a seepage prevention cover 81 is slidably connected to the outer surface of the second pipe 2. The side of the seepage prevention cover 81 closest to the first pipe 1 is in contact with the seepage prevention shell 8. A plurality of circumferentially arranged locking screws 9 are rotatably connected to one side of the seepage prevention shell 8. The threaded portion of each of the locking screws 9 is threadedly connected to the seepage prevention cover 81.

[0025] As an optional technical solution of this utility model, a plurality of circumferentially arrayed splicing pins 10 are fixedly connected to the side of the seepage-proof cover 81 near the first pipe 1, and a plurality of circumferentially arrayed splicing sleeves 11 are fixedly connected to the outer surface of the seepage-proof shell 8. The plurality of splicing pins 10 are inserted into the splicing sleeves 11. Through the insertion and cooperation of the splicing pins 10 and the splicing sleeves 11, the seepage-proof cover 81 and the seepage-proof shell 8 can be quickly and accurately positioned and assembled, ensuring that the connection between the two is stable and the sealing performance is good, while facilitating disassembly and maintenance.

[0026] As an optional technical solution of this utility model, a blocking ring 12 is fixedly connected to the outer surface of the first pipe 1. A plurality of arc-shaped limiting strips 13 in a circular array are fixedly connected between the blocking ring 12 and the first flange ring 3. A plurality of arc-shaped limiting grooves 14 in a circular array are opened on the inner wall of the seepage-proof shell 8. The seepage-proof shell 8 is slidably connected to the arc-shaped limiting strips 13 through the arc-shaped limiting grooves 14. The sliding connection between the arc-shaped limiting strips 13 and the arc-shaped limiting grooves 14 provides precise installation guidance for the seepage-proof shell 8. The blocking ring 12 restricts the movement range of the seepage-proof shell 8, ensuring that the seepage-proof shell 8 can accurately cover the flange connection part, thereby improving installation efficiency and protection effect.

[0027] As an optional technical solution of this utility model, the anti-seepage cover 81 has a plurality of circumferentially arrayed threaded holes 15 on the side near the first pipe 1. The screws of a plurality of locking screws 9 are threadedly connected to the anti-seepage cover 81 through the threaded holes 15. The setting of the threaded holes 15 enables the locking screws 9 to firmly fix the anti-seepage cover 81, ensuring that the connection between the anti-seepage cover 81 and the anti-seepage shell 8 is tight and reliable, preventing the connection from loosening due to vibration or external force, and maintaining long-term stable sealing performance.

[0028] As an optional technical solution of this utility model, a rubber sealing ring 16 is fixedly connected to the side of the anti-seepage cover 81 near the first pipe 1, and a sealing groove 17 is opened on one side of the anti-seepage shell 8. The rubber sealing ring 16 is slidably connected to the anti-seepage shell 8 through the sealing groove 17. The tight cooperation between the rubber sealing ring 16 and the sealing groove 17 forms a reliable waterproof barrier, effectively preventing external moisture from seeping into the connection part, enhancing the overall anti-seepage effect, and at the same time having good elastic compensation ability to adapt to the thermal expansion and contraction of the pipeline.

[0029] As an optional technical solution of this utility model, the inner wall of the seepage-proof shell 8 is provided with a plurality of hexagonal limiting grooves 18 arranged in a circular array. The nut part of the bolt 6 is designed with hexagons. The nut part of the bolt 6 is slidably connected to the seepage-proof shell 8 through the hexagonal limiting grooves 18. The cooperation between the hexagonal limiting grooves 18 and the hexagonal head of the bolt 6 can not only prevent the bolt from rotating during installation and facilitate the tightening operation, but also quickly locate the bolt position during maintenance, simplify the disassembly process, and improve maintenance efficiency.

[0030] As an optional technical solution of this utility model, a number of circumferential array sealing covers 19 are fixedly connected to one side of the seepage-proof cover 81. A number of nuts 7 are located inside the number of sealing covers 19 respectively. The sealing covers 19 completely enclose the nuts 7 to form an independent sealing space, effectively isolating the nuts from external environmental corrosion, preventing loosening of the connection due to rust, and extending the service life of the pipe connection.

[0031] A seepage prevention device for water supply and drainage pipes in building engineering operates on the following principle:

[0032] 1) The connection between the first flange ring 3 and the second flange ring 4 is completely covered. During installation, first place the sealing ring 5 between the two flange rings, and then tighten it with bolts 6 and nuts 7.

[0033] 2): Slide the seepage-proof shell 8 so that its arc-shaped limiting groove 14 moves along the arc-shaped limiting strip 13 to completely cover the flange connection. Then insert the splicing pin 10 of the seepage-proof cover 81 into the splicing sleeve 11, and finally tighten the locking screw 9 to complete the assembly.

[0034] 3) The tight fit between the rubber sealing ring 16 and the sealing groove 17 forms the first waterproof barrier between the seepage-proof shell 8 and the seepage-proof cover 81, while the sealing cover 19 completely encloses the nut 7 to form the second layer of protection. When maintenance is required, the seepage-proof cover 8 can be removed simply by loosening the locking screw 9.

[0035] In summary, the seepage prevention device for water supply and drainage pipes in this building project, through the cooperative structure of the seepage prevention shell 8 and the seepage prevention cover 81, completely encloses the connection between the first flange ring 3 and the second flange ring 4. During installation, the sealing ring 5 is first placed between the two flange rings, and then tightened with bolts 6 and nuts 7. The seepage prevention shell 8 is then slid to move its arc-shaped limiting groove 14 along the arc-shaped limiting strip 13 until it completely covers the flange connection. Then, the splicing pin 10 of the seepage prevention cover 81 is inserted into the splicing sleeve 11, and finally the locking screw 9 is tightened to complete the assembly. This double protection design ensures that the bolts 6 and nuts 7 are completely protected by the sealing cover 19 and the seepage prevention shell 8, effectively isolating environmental factors such as rainwater and moisture, preventing fastener corrosion that could lead to loosening of the connection, and fundamentally solving the problem of easy water leakage in traditional flange connections. The hexagonal limiting groove 18 and the hexagonal head of bolt 6 prevent bolt rotation during maintenance, facilitating disassembly and maintenance. A modular sealing structure is employed; the tight fit between the rubber sealing ring 16 and the sealing groove 17 forms the first waterproof barrier between the seepage-proof shell 8 and the seepage-proof cover 81, while the sealing cover 19 completely encloses the nut 7, forming a second layer of protection. When maintenance is required, the seepage-proof cover 81 can be removed simply by loosening the locking screw 9, making operation convenient. The sliding connection between the arc-shaped limiting strip 13 and the arc-shaped limiting groove 14 ensures accurate positioning of the seepage-proof shell 8 during installation, while the blocking ring 12 restricts the movement range of the seepage-proof shell 8. This design not only provides comprehensive protection for the connection points, but its detachable structure also facilitates regular inspection of the flange connection status, significantly extending the service life of the pipeline system and reducing maintenance costs. The insertion fit between the splicing pin 10 and the splicing sleeve 11 further improves assembly accuracy, ensuring the sealing performance of the seepage-proof cover 81 and the seepage-proof shell 8.
