Description

Technical Field

[0001] This utility model relates to the field of emergency repair technology for urban water supply networks, specifically an emergency repair device for leaking elbows in urban water supply networks. Background Technology

[0002] Currently, urban water supply networks are divided into main pipelines, branch pipelines, and minor branch pipelines. These pipelines, at various levels, form a water supply network providing tap water services for urban residents, businesses, and other daily needs. Most existing water supply pipelines are made of PE (polyethylene) material, buried deep underground, secured with fine sand and soil, and covered by city roads or sidewalks. With current technology, damage and leaks in water supply pipelines are inevitable due to road surface wear or years of neglect. In such cases, water outages are necessary for emergency repairs to plug the leaks, which inevitably causes significant inconvenience to urban production and daily life. Therefore, pipeline repairs must be swift, aiming to plug the leaks and restore normal urban water supply in the shortest possible time.

[0003] During emergency repairs of urban water supply pipelines, leaks at pipe bends are frequently encountered. Due to the internal water pressure, bends bear greater pressure than straight sections. During repairs, even after using spare bends, leaks may still occur if the bends do not properly connect to the straight sections at both ends or if the pipes detach. This leads to the undesirable consequences of secondary repairs and prolongs water outages. Leaks at bends are a difficult and challenging aspect of emergency water supply repairs. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide an emergency repair device for leaking elbows in urban water supply networks, which can effectively fix the spare elbow to the straight pipes at both ends, ensure that the pipe connection is firm and does not fall off or leak, shorten the water outage time, and improve the repair efficiency.

[0005] To achieve the above-mentioned invention objectives, the water pipe in the inlet direction of this utility model is connected to the water pipe in the outlet direction via a half-joint elbow. The water pipe in the inlet direction is bolted with a fixing clamp one, and the water pipe in the outlet direction is bolted with a fixing clamp two. The fixing clamp one is bolted to the fixing clamp two via a connecting rod.

[0006] Furthermore, the inlet water pipe, outlet water pipe, and elbow are made of PE material, while the fixing clamp one, fixing clamp two, and connecting rod are made of stainless steel.

[0007] Furthermore, the elbow joint is one of the following: a straight pipe elbow joint, an elbow elbow joint, a tee elbow joint, or a reducing elbow joint.

[0008] Furthermore, the half-section elbow is composed of an upper shell body and a lower shell body connected by connecting bolts, and a rubber sealing gasket is provided between the upper shell body and the lower shell body.

[0009] Furthermore, the fixing clamp 1 includes a pair of mutually closed semicircular rings 1, each of which has a round hole 1 at both ends of the semicircular ring 1 for mounting ears, and a connecting bolt 2 passes through the round hole 1 to fix the fixing clamp 1 to the water pipe in the direction of water inlet; the top of the fixing clamp 1 is also provided with a connecting plate 1 that is connected to the connecting rod bolt; the fixing clamp 1 is fixed at the water pipe in the direction of water inlet located at the half joint elbow, and is pressed against one end of the half joint elbow;

[0010] The fixing clamp 2 includes a pair of mutually closed semicircular rings 2. The two ends of the semicircular rings 2 are respectively provided with opposing circular holes 2. The connecting bolts 3 pass through the circular holes 2 to fix the fixing clamp 2 to the water pipe in the direction of water flow. The top of the fixing clamp 2 is also provided with a connecting plate 2 that is connected to the connecting rod bolt. The fixing clamp 2 is fixed at the water pipe in the direction of water flow at the half-joint elbow and is pressed against the other end of the half-joint elbow.

[0011] Furthermore, the connecting rods are in three sets, located on both sides and the top of the first and second fixing clamps, respectively.

[0012] Furthermore, the connecting rod has waist-shaped holes at both ends, and the connecting bolts pass through the waist-shaped holes at both ends to connect the connecting rod to the connecting plate one at the top of the fixing clamp one and the connecting plate two at the top of the fixing clamp two, respectively.

[0013] Furthermore, the second connecting bolt on the first fixing clamp passes through the oblong hole at one end of the connecting rod to connect one end of the connecting rod to one side of the first fixing clamp; the third connecting bolt passes through the oblong hole at the other end of the connecting rod to connect the other end of the connecting rod to one side of the second fixing clamp.

[0014] Furthermore, one of the three sets of connecting rods is connecting rod one, which is composed of two connecting rods spliced ​​together, and its splicing angle is adapted to the angle of the half joint elbow.

[0015] Compared with existing technologies, this utility model, during emergency repairs of urban water supply systems, first replaces the leaking half-joint elbow, connecting it to the incoming and outgoing water pipes. Fixing clamps one and two are then tightened at both ends of the half-joint elbow. Three sets of connecting rods in different positions are then used to bolt the upper and lower fixing clamps together, further securing the half-joint elbow to the incoming and outgoing water pipes. This effectively prevents the elbow from detaching, cracking, and leaking due to the impact of high water pressure at the elbow joint, shortening repair time and improving efficiency. After the emergency repair device is installed, backfilling and hardening the road surface restores normal water supply. This utility model has a simple, reliable, economical, practical, and highly operable structure. Attached Figure Description

Stainless steel fixing clamps and connecting rods are corrosion-resistant, high-strength, and suitable for underground environments.

[0030] Preferably, the elbow 3 is one of a straight pipe elbow, a bend elbow, a tee elbow, or a reducing elbow. Different types of elbows are suitable for different water supply scenarios, and the emergency repair device of this utility model can be used to fix the elbow in all of them. As a different embodiment, when applied to a tee elbow, three sets of water pipe fixing clamps are used to fix and connect to three sets of water pipes respectively. The connecting rod on each set of fixing clamps is connected to the other two sets of fixing clamps in pairs to form a whole, ensuring that the tee elbow is fixedly connected to the three sets of water pipes and that the tee elbow does not fall off.

[0031] Preferably, the half-joint elbow 3 is composed of an upper half-shell body 3-1 and a lower half-shell body 3-2 connected by connecting bolts 3-3, which makes installation convenient. A rubber sealing gasket 3-4 is provided between the upper half-shell body 3-1 and the lower half-shell body 3-2 to ensure that the upper and lower half-shell bodies are tightly connected and there is no leakage.

[0032] Preferably, the fixing clamp 4 includes a pair of mutually closed semicircular rings 4-1. The two ends of the semicircular rings 4-1 are respectively provided with opposing circular holes 4-2. The connecting bolts 4-3 pass through the circular holes 4-2 to fix the fixing clamp 4 to the water pipe 1 in the direction of water flow. The top of the fixing clamp 4 is also provided with a connecting plate 4-4 that is bolted to the connecting rod 6. The fixing clamp 4 is fixed at the water pipe 1 in the direction of water flow at the half-joint elbow 3 and is pressed against one end of the half-joint elbow 3.

[0033] The fixing clamp 25 includes a pair of mutually closed semicircular rings 25-1. The two ends of the semicircular rings 25-1 are respectively provided with opposing circular holes 25-2. The connecting bolts 35-3 pass through the circular holes 25-2 to fix the fixing clamp 25 to the water pipe 2 in the direction of water flow. The top of the fixing clamp 25 is also provided with a connecting plate 25-4 that is bolted to the connecting rod 6. The fixing clamp 25 is fixed at the water pipe 2 in the direction of water flow of the split elbow 3 and is pressed against the other end of the split elbow 3.

[0034] Preferably, the connecting rod 6 is in three sets, located on both sides and top of the first fixing clamp 4 and the second fixing clamp 5 respectively, connecting and fixing the first fixing clamp 4 and the second fixing clamp 5 together from three different angles.

[0035] Preferably, the connecting rod 6 has oblong holes 6-1 at both ends. The oblong holes 6-1 facilitate the installation and adjustment of the connecting rod 6, adapting to different assembly scenarios. The connecting bolts 6-2 pass through the oblong holes 6-1 at both ends to connect the connecting rod 6 to the connecting plate 4-4 at the top of the fixing clamp 4 and the connecting plate 5-4 at the top of the fixing clamp 5, respectively.

[0036] Preferably, the connecting bolt 4-3 on the fixing clamp 4 passes through the waist-shaped hole 6-1 at one end of the connecting rod 6 to connect one end of the connecting rod 6 to one side of the fixing clamp 4; the connecting bolt 5-3 passes through the waist-shaped hole 6-1 at the other end of the connecting rod 6 to connect the other end of the connecting rod 6 to one side of the fixing clamp 5.

[0037] Preferably, one of the three sets of connecting rods 6 is connecting rod 6-3, which is composed of two connecting rods spliced ​​together, and the splicing angle is adapted to the angle of the half-joint elbow 3.

[0038] In the application of this utility model, during emergency repairs of the city's main water supply system, the damaged and leaking elbow 3 is first replaced. The replaced elbow 3 is then connected to the incoming water pipe 1 and the outgoing water pipe 2. Next, fixing clamps 1 and 2 are bolted to the incoming and outgoing water pipes 1 and 2 respectively, ensuring they are firmly pressed against both ends of the elbow 3. Three sets of connecting rods 6 are used to secure the clamps 1 and 2, preventing the elbow 3 between the incoming and outgoing water pipes from detaching or leaking due to high water pressure. After the repairs are completed, the area around the pipeline is backfilled with sand, the road surface is hardened, and normal water supply is restored.

[0039] In actual maintenance, although leaks at pipe bends can be addressed by replacing large sections of the leaking pipe, constructing concrete blocks to support the bends, and improving the overall strength of the pipeline, these methods inevitably involve large-scale earthwork excavation and prolonged cement setting time. This results in lengthy project cycles, high maintenance costs, and extended water outages, which are detrimental to the fast pace of urban life. This invention can quickly resolve pipe leaks, especially at bends, shortening maintenance time, reducing water outages, and rapidly restoring urban water supply.
