Description

Technical Field

[0001] This utility model belongs to the field of pipeline emergency repair technology, and more specifically, it relates to a quick-repair connection pipe fitting for preventing leakage in water supply pipelines of water conservancy projects. Background Technology

[0002] During the operation of water pipelines in water conservancy projects, pipeline leakage is a common fault. To address this type of fault, the industry currently mostly uses emergency repair clamps for emergency repairs. The core structure consists of two semi-circular clamps. By wrapping the clamps around the damaged part of the pipeline and then tightening the clamps with multiple bolts, the clamps form a sealed fit with the outer wall of the pipeline, thereby achieving the effect of preventing leakage.

[0003] For example, existing application number CN202422628110.4 relates to the field of pipe fittings, and in particular to a ring-clamp sealing mechanical pipe fitting, including a pipe fitting with a plug hole, a ring-clamp connector inserted into the plug hole, a pressure plate fixed on the ring-clamp connector, a sealing gasket between the pressure plate and the pipe fitting, and a back plate detachably connected to the pressure plate. By making the pipe fitting and the ring-clamp connector detachably connected, compared with conventional tee fittings, the flexibility of operation and use is greatly increased. It can be used as a tee, and during pipeline installation, modification and upgrading, branch pipes can be directly connected to the system pipeline, which is convenient to install. During pipeline emergency repair, the on-site construction speed is fast, no water interruption is required, and the construction excavation is small, requiring only a small working pit to operate, saving a lot of manpower, material resources and time, and achieving the purpose of rapid leak sealing.

[0004] Based on the above, after the emergency repair clamps are wrapped around the damaged part of the water pipeline, the pipeline is highly susceptible to instantaneous fluctuations caused by the start-up and shutdown of the water pump and the impact of water flow. These fluctuations not only cause pipeline vibration, but also, if there is erosion or settlement of the surrounding soil, can lead to pipeline displacement. This displacement can then cause the emergency repair clamps wrapped around the pipeline to shift synchronously. Once the clamps shift, their sealed fit with the pipeline is compromised, which can easily lead to high-pressure water leakage. Leakage not only wastes water resources, but also easily causes the surrounding soil to collapse and roads to be damaged. Furthermore, when emergency repairs are carried out in confined spaces or near electrical equipment, the leaking water can easily cause electric shock, slips, and other safety accidents, posing a significant threat to the operation of the project and the safety of personnel. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a rapid repair connection fitting for water supply pipelines in water conservancy projects. This fitting solves the problem that when repair clamps are wrapped around damaged sections of the pipeline, they are highly susceptible to momentary fluctuations caused by pump start-ups and shutdowns, water flow impacts, and other operating conditions. These fluctuations not only cause pipeline vibration but also, if the surrounding soil experiences erosion or settlement, lead to pipeline displacement. This displacement causes the repair clamps wrapped around the pipeline to shift synchronously, disrupting the seal between the clamps and the pipeline and easily leading to high-pressure water leakage. Such leakage not only wastes water resources but also easily causes surrounding soil collapse and road damage. Furthermore, when repairs are carried out in confined spaces or near electrical equipment, the leaking water can easily cause electric shocks, slips, and other safety accidents, posing a significant threat to project operation and personnel safety.

[0006] The purpose and effectiveness of this utility model for a rapid repair connection fitting for preventing leakage in water conveyance pipelines of water conservancy projects are achieved through the following specific technical means: A rapid repair connection fitting for leak-proof water transmission pipelines in water conservancy projects includes a first arc-shaped frame, a second arc-shaped frame, a pressure relief pipe, a positioning and locking mechanism, positioning studs, and an installation auxiliary mechanism. The second arc-shaped frame is connected to the top end face of the first arc-shaped frame; the pressure relief pipe is fixedly connected to the lower end of the first arc-shaped frame; the positioning and locking mechanism is disposed between the mating surfaces of the first and second arc-shaped frames on the left and right sides; sealing auxiliary gaskets are fixedly connected to the mating surfaces of the first and second arc-shaped frames and the pipeline; multiple installation through holes are evenly arranged on the left and right sides of the first and second arc-shaped frames; multiple positioning studs are provided, and each positioning stud is threadedly connected to a multiple installation through hole; the installation auxiliary mechanism is disposed inside the left and right ends of the first arc-shaped frame; the installation auxiliary mechanism includes: multiple positioning support rings, which are rotatably connected to the left and right ends of the first arc-shaped frame, and are coaxially arranged with the multiple installation through holes.

[0007] Furthermore, the positioning and locking mechanism includes: docking brackets, there are two docking brackets, the two docking brackets are respectively fixedly connected to the left and right sides of the contact area between the second arc frame and the first arc frame; docking guide grooves adapted to the docking brackets are opened on the left and right sides of the contact area between the first arc frame and the second arc frame.

[0008] Furthermore, the positioning and locking mechanism also includes: an assist bracket and a locking bracket. There are two assist brackets, which are fixedly connected to two docking brackets respectively. There are two sets of locking brackets, which are elastically connected to the left and right sides of the first arc-shaped frame by multiple return springs. The contact surfaces of the assist brackets and the two sets of locking brackets on both sides are sloped structures.

[0009] Furthermore, a sealing stud is threadedly connected to the inner side of the pressure relief pipe; the inner wall of the pressure relief pipe is provided with a thread adapted to the sealing stud; and a sealing tape is wrapped around the thread of the sealing stud.

[0010] Furthermore, the installation auxiliary mechanism also includes: a limiting protrusion, wherein there are multiple limiting protrusions, and the multiple limiting protrusions are respectively fixedly connected to multiple positioning support rings; a limiting groove adapted to the limiting protrusion is provided at the connection between the positioning stud and the mounting through hole.

[0011] Furthermore, the installation auxiliary mechanism also includes: a transmission helical gear and a drive helical gear. There are multiple transmission helical gears, which are coaxially and fixedly connected to multiple positioning support rings respectively. There are multiple drive helical gears, which are evenly arranged at the left and right ends of the second arc-shaped frame. The drive helical gears on the same side are rotatably connected to the second arc-shaped frame through connecting support shafts. The drive helical gears on the same side mesh with the transmission helical gears.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In use, this utility model, through the cooperation of the positioning and locking mechanism and the positioning stud, not only achieves dual restriction on the two arc-shaped frames in both the lateral and longitudinal directions to prevent displacement of the arc-shaped frames, but also realizes the quick docking and locking of the first arc-shaped frame and the second arc-shaped frame. Furthermore, through the reverse clamping force of the locking bracket on the auxiliary bracket, it can resist the displacement tension caused by pipeline vibration, water flow impact and soil settlement, and prevent the arc-shaped frame from failing to seal due to pipeline displacement. Moreover, through the cooperation of the positioning stud, the fixing effect between the arc-shaped frame and the pipeline is further strengthened, which greatly avoids the risk of leakage of high-pressure water flow. When in use, this utility model can quickly discharge residual water pressure and air in the pipeline before installation through the pressure relief pipe. This not only avoids the phenomenon of residual pressure pushing open the arc frame or pushing the pipe fittings to shift, thus reducing the difficulty of installation, but also reduces the instantaneous impact of high pressure on the sealing auxiliary gasket, avoids the sealing component from being deformed by pressure and thus extends the service life of the seal. When in use, this utility model, with the cooperation of the installation auxiliary mechanism, enables the synchronous rotation of multiple positioning studs. The operator only needs to rotate any one positioning stud to drive all positioning studs on the same side to be tightened synchronously through gear transmission. This ensures that the preload of each stud is uniform and consistent, avoiding the gap caused by uneven local force, and also saves the tedious step of aligning and tightening the studs one by one, significantly shortening the repair time. This utility model enhances the anti-leakage effect, reduces water waste, and avoids engineering accidents such as soil subsidence and road damage caused by seepage. Especially in emergency repair scenarios in confined spaces or near electrical equipment, the reliable anti-leakage performance can eliminate the risk of electric shock caused by water contacting electrical equipment, as well as the risk of slipping and falling due to wet ground, providing dual protection for the safety of repair personnel and the stable operation of the project.

The contact surfaces of the assist brackets 401 and the two sets of locking brackets 402 are all sloped structures.

[0024] The pressure relief pipe 3 has a threaded connection to a sealing stud 301 on its inner side; the inner wall of the pressure relief pipe 3 has a thread that matches the sealing stud 301; and a sealing tape is wrapped around the thread of the sealing stud 301.

[0025] The specific usage and function of this embodiment are as follows: In use, after the first arc-shaped frame 1 and the second arc-shaped frame 2 are wrapped around the leak in the water pipe, and the positions of the docking bracket 4 and the docking guide groove 101 are aligned, the first arc-shaped frame 1 and the second arc-shaped frame 2 are pushed towards the pipe.
