A leak-proof pipeline for water conservancy projects with strong structural stability

Abstract

The present invention provides a leak-proof pipeline for water conservancy projects with strong structural stability, which relates to the field of water conservancy pipelines and includes: an engineering water pipe. A central support bracket is arranged at the connection of the engineering water pipes. Flap pieces are arranged on the outer sides of the opposite pipe walls of the two engineering water pipes. Squeezing collar rings are threadedly connected to the left and right inner side walls of the central support bracket. A propulsion ring is arranged between the squeezing collar rings and the side walls of the central support bracket. By driving the rotation of the adjustment dial, the squeezing collar rings are driven to rotate. As the inner side of the squeezing collar rings extends into the connection groove, the propulsion rings connected to the inner side of the squeezing collar rings squeeze the airbag sealing ring, so that the airbag sealing ring fills the gaps of the entire connection groove. The squeezing force on the airbag sealing ring can be adjusted by driving the squeezing collar rings through the adjustment dial, further improving the sealing performance at the connection groove between the flap pieces of the engineering water pipes and the central support bracket, avoiding leakage, improving the leak-proof effect, and solving the problem that the structural stability is reduced due to leakage at the pipeline connection.

Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy pipelines, and particularly relates to a leak-proof pipeline for water conservancy projects with strong structural stability. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Only by building water conservancy projects can water flow be controlled, flood disasters be prevented, and water volume be regulated and distributed to meet the needs of people's lives and production for water resources. The water conveyance pipelines in water conservancy projects are essential.

[0003] However, for the existing leak-proof pipelines for water conservancy projects with strong structural stability, since the pipelines are connected by fusion welding or welding, leakage often occurs due to the lack of weld seams, resulting in poor structural stability at the pipeline joints and easily causing pipeline cracking. Summary of the Invention

[0004] In view of this, the present invention provides a leak-proof pipeline for water conservancy projects with strong structural stability. By rotating the adjustment dial to drive the extrusion collar to rotate, as the inner side of the extrusion collar extends into the connection groove, the propulsion ring connected to the inner side of the extrusion collar squeezes the airbag sealing ring, causing the airbag sealing ring to fill the gaps in the entire connection groove. As the usage time increases, the extrusion force on the airbag sealing ring can be adjusted by driving the extrusion collar through the adjustment dial, further improving the sealing performance at the connection groove between the baffle and the central support bracket of the project water pipe, avoiding leakage, and improving the leak-proof effect.

The transmission rod is horizontally rotatably connected to the middle of the central support bracket.

[0006] Further, two connection grooves are respectively opened in the left and right side walls of the central support bracket, external connection threads are opened on the arc-shaped end surfaces at the bottoms of the connection grooves near the outer circle of the left and right side walls of the central support bracket, the external connection threads are connected to the internal threads provided in the side walls of the extrusion collar, and connection rotation grooves are opened at the outermost circles of the left and right side walls of the central support bracket.

[0007] Further, the baffle on the outer wall of one side of the engineering water pipe is snap-fitted into the connecting groove near the inner ring on the left and right side walls of the central support bracket. An airbag seal ring is sleeved on the outer wall of the engineering water pipe, and the airbag seal ring is arranged on one side of the baffle.

[0008] Further, a rotation connection groove is formed in the inner ring side wall at the connection between the extrusion collar and the central support bracket. The rotation connection groove is connected to the rotation connection ring on one side of the propulsion ring. The propulsion ring is slidably connected in the connection groove near the inner ring of the central support bracket. An airbag seal ring is arranged between the propulsion ring and the baffle of the engineering water pipe.

[0009] Further, a guide groove is formed on the outer side wall of the extrusion collar. The adjusting scale disc is slidably connected in the guide groove through a guide block. A connection rotating ring is arranged on one side wall of the adjusting scale disc, and the connection rotating ring is rotatably connected in the connection rotating groove of the central support bracket.

[0010] Further, a longitudinal central column is arranged in the middle of the central support bracket. A central cross bar is arranged in the middle of the central column.

Thread grooves with opposite thread directions are arranged at the left and right ends of the transmission rod, and sliding seats are threadedly connected to the thread grooves.

[0012] Further, support rods are connected to the outer side walls of the four sides of the sliding seat and the hinge seats on the outer side wall of the central cross bar of the central support bracket. A support arc plate is arranged at the hinge joint of the two support rods, and the outer side wall of the support arc plate is arc-shaped.

[0013] Further, a seal sleeve is arranged on the outer side wall of the engineering water pipe, and the two seal sleeves are connected by magnetic attraction connection.

[0014] Beneficial effects

[0015] According to the embodiments of the present invention, the pipeline for water conservancy projects inserts the baffle end of the project water pipe into it through the connection groove near the inner ring of the central support bracket. Then, a special tool is used to drive the adjustment scale disk to rotate. The adjustment scale disk is rotationally connected to the connection rotating groove of the central support bracket through the connection rotating ring. Since the guide block of the adjustment scale disk is slidably connected to the guide groove, the rotation of the adjustment scale disk drives the extrusion collar to rotate. As the extrusion collar rotates, the internal thread of the extrusion collar is connected to the external connection thread, fixing the extrusion collar on the central support bracket, so as to fix the outer side wall of the connection between the project water pipe and the central support bracket through the extrusion collar, improve the structural stability of the connection between the project water pipe and the central support bracket, prevent the connection between the project water pipe and the central support bracket from breaking, and improve the connection strength.

[0016] In addition, as the adjustment scale disk rotates to drive the extrusion collar to rotate, as the inner ring side of the extrusion collar penetrates deeper into the connection groove, the propulsion ring connected to the inner ring side of the extrusion collar squeezes the airbag sealing ring, filling the gap of the entire connection groove with the airbag sealing ring. As the use time increases, the extrusion force on the airbag sealing ring can be adjusted by driving the extrusion collar with the adjustment scale disk, further improving the sealing performance at the connection groove between the baffle of the project water pipe and the central support bracket, avoiding leakage, and improving the anti-leakage effect.

[0017] In addition, insert the baffle ends of the two project water pipes into the connection grooves on the left and right sides of the central support bracket. Then, insert a special tool into the top end face of the adjustment rod and rotate it. Through the left end of the adjustment rod, the driving bevel gear at the bottom of the adjustment rod drives the transmission bevel gear in the middle of the transmission rod to rotate, causing the transmission rod to rotate. Through the rotation of the transmission rod, the threaded grooves at both ends of the transmission rod control the movement of the sliding seat. As the sliding seat moves, the distance between the two support rods is changed, and the support arc plate is pushed to support and fix from inside the project water pipe, ensuring that both project water pipes are in the central position and cooperating with the extrusion collar to fix the connection between the project water pipe and the central support bracket, ensuring the structural stability and high strength of the connection.

[0035] The present invention provides a leak-proof pipeline for water conservancy projects with strong structural stability, including an engineering water pipe 1. A central support bracket 2 is provided at the connection of the engineering water pipe 1. Flap pieces 101 are provided on the outer sides of the opposite pipe walls of the two engineering water pipes 1. An extrusion collar 5 is threadedly connected to the left and right inner side walls of the central support bracket 2. A propulsion ring 4 is provided between the outer side wall of the extrusion collar 5 and the side wall of the central support bracket 2. A regulating scale disc 6 is slidably connected to the outer side wall of the extrusion collar 5. A regulating rod 7 is longitudinally provided inside the central support bracket 2. The bottom of the regulating rod 7 is meshed with the middle of a transmission rod 8. Sliding seats 9 are threadedly connected to both ends of the transmission rod 8. The transmission rod 8 is horizontally rotatably connected to the middle of the central support bracket 2.

[0036] Among them, two connection grooves 201 are respectively opened in the left and right side walls of the central support bracket 2. External connection threads 202 are opened on the arc-shaped end surfaces at the bottoms of the connection grooves 201 near the outer circles of the left and right side walls of the central support bracket 2. The external connection threads 202 are connected to the internal threads 502 provided in the side walls of the extrusion collar 5. Connection rotation grooves 203 are opened at the outermost circles of the left and right side walls of the central support bracket 2. A guiding groove 503 is opened on the outer side wall of the extrusion collar 5. The regulating scale disc 6 is slidably connected to the guiding groove 503 through a guiding block 602. A connection rotating ring 601 is provided on one side wall of the regulating scale disc 6. The connection rotating ring 601 is rotatably connected to the connection rotation groove 203 of the central support bracket 2.

[0037] With the above technical solution, the flap piece 101 end of the engineering water pipe 1 is inserted into the connection groove 201 near the inner circle of the central support bracket 2, and then the regulating scale disc 6 is driven to rotate by a special tool. The regulating scale disc 6 is rotatably connected to the connection rotation groove 203 of the central support bracket 2 through the connection rotating ring 601. Since the guiding block 602 of the regulating scale disc 6 is slidably connected to the guiding groove 503, the rotation of the regulating scale disc 6 drives the extrusion collar 5 to rotate. As the extrusion collar 5 rotates, the internal threads 502 of the extrusion collar 5 are threadedly connected to the external connection threads 202, so that the extrusion collar 5 is fixed on the central support bracket 2, so as to fix the outer side wall at the connection of the engineering water pipe 1 and the central support bracket 2, so as to improve the structural stability at the connection of the engineering water pipe 1 and the central support bracket 2, thereby preventing fractures at the connection of the engineering water pipe 1 and the central support bracket 2 and improving the connection strength.

[0038] Embodiment 2:

[0039] Among them, a rotating connection groove 501 is provided in the inner ring side wall at the connection between the extrusion collar 5 and the central support bracket 2. The rotating connection groove 501 is connected to the rotating connection ring 401 on one side of the propulsion ring 4. The propulsion ring 4 is slidably connected in the connection groove 201 near the inner ring of the central support bracket 2. An airbag seal ring 3 is provided between the propulsion ring 4 and the baffle 101 of the engineering water pipe 1.

An airbag seal ring 3 is sleeved on the outer side wall of the engineering water pipe 1, and the airbag seal ring 3 is arranged on one side of the baffle 101.

[0040] With the above technical solution, by adjusting the rotation of the scale disk 6 to drive the rotation of the extrusion collar 5, as the inner ring side of the extrusion collar 5 penetrates into the connection groove 201, the propulsion ring 4 connected to the inner ring side of the extrusion collar 5 squeezes the airbag seal ring 3, so that the airbag seal ring 3 fills the gap of the entire connection groove 201. As the use time increases, the extrusion force on the airbag seal ring 3 can be adjusted by driving the extrusion collar 5 through the scale disk 6, further improving the sealing performance at the connection groove 201 between the baffle 101 of the engineering water pipe 1 and the central support bracket 2, avoiding leakage, and improving the leak prevention effect.

A support arc plate 11 is provided at the hinge of the two support rods 10. The outer side wall of the support arc plate 11 is arc-shaped. A seal sleeve 12 is provided on the outer side wall of the engineering water pipe 1. The two seal sleeves 12 are connected by magnetic attraction.

[0044] With the above technical solution, first insert the flap 101 ends of the two engineering water pipes 1 into the connection grooves 201 on the left and right sides of the central support bracket 2, then insert a special tool into the top end face of the adjusting rod 7 and rotate it. Through the left end of the adjusting rod 7, the driving bevel gear 701 at the bottom of the adjusting rod 7 drives the transmission bevel gear 801 in the middle of the transmission rod 8 to rotate, causing the transmission rod 8 to rotate. Through the rotation of the transmission rod 8, the threaded grooves 802 at both ends of the transmission rod 8 control the movement of the sliding seat 9. As the sliding seat 9 moves, the distance between the two support rods 10 is changed, and the support arc plate 11 is pushed to support and fix from inside the engineering water pipe 1, ensuring that both engineering water pipes 1 are in the central position and cooperating with the extrusion collar 5 to fix the connection between the engineering water pipe 1 and the central support bracket 2, ensuring the stability and high strength of the connection structure.

[0045] Specific usage method and function of this embodiment: In the present invention, first insert the flap 101 ends of the two engineering water pipes 1 into the connection grooves 201 on the left and right sides of the central support bracket 2, then insert a special tool into the top end face of the adjusting rod 7 and rotate it. Through the left end of the adjusting rod 7, the driving bevel gear 701 at the bottom of the adjusting rod 7 drives the transmission bevel gear 801 in the middle of the transmission rod 8 to rotate, causing the transmission rod 8 to rotate. Through the rotation of the transmission rod 8, the threaded grooves 802 at both ends of the transmission rod 8 control the movement of the sliding seat 9. As the sliding seat 9 moves, the distance between the two support rods 10 is changed, and the support arc plate 11 is pushed to support and fix from inside the engineering water pipe 1, ensuring that both engineering water pipes 1 are in the central position. Then, drive the adjusting scale disk 6 to rotate through the special tool. The adjusting scale disk 6 is rotationally connected to the connection rotating groove 203 of the central support bracket 2 through the connection rotating ring 601. Since the guiding block 602 of the adjusting scale disk 6 is slidably connected in the guiding groove 503, the rotation of the adjusting scale disk 6 drives the extrusion collar 5 to rotate. As the extrusion collar 5 rotates, the internal thread 502 of the extrusion collar 5 is threadedly connected to the external connection thread 202, fixing the extrusion collar 5 on the central support bracket 2, so as to fix the outer side wall of the connection between the engineering water pipe 1 and the central support bracket 2 through the extrusion collar 5. As the inner side of the extrusion collar 5 penetrates into the connection groove 201, the pushing ring 4 connected to the inner side of the extrusion collar 5 squeezes the airbag sealing ring 3, causing the airbag sealing ring 3 to fill the gap of the entire connection groove 201. As the usage time increases, the squeezing force on the airbag sealing ring 3 can be adjusted by driving the extrusion collar 5 through the adjusting scale disk 6, further improving the sealing performance at the connection groove 201 between the flap 101 of the engineering water pipe 1 and the central support bracket 2 and avoiding leakage.
