Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering pipeline connection device. Background Technology

[0002] Water conservancy projects refer to various projects such as flood control, drainage, irrigation, hydropower generation, water diversion (supply), tidal flat management, soil and water conservation, and water resource protection. Water conservancy projects are constructed to eliminate water hazards and develop and utilize water resources. The construction of water conservancy projects not only controls water flow and prevents floods, but also regulates and distributes water to meet the needs of people's lives and production. During the long-term use of pipelines in water conservancy projects, pipelines may be damaged, and they need to be replaced.

[0003] Chinese Patent Publication No. CN220566812U discloses a pipe connection device for water conservancy projects, including a first pipe, a second pipe, a first flange, a second flange, and four fastening components. The first flange and the second flange are respectively located at adjacent ends of the first pipe and the second pipe. A guide tube is provided on the inner wall of the second flange, and the outer wall of the guide tube is sequentially fitted to the inner walls of the first flange and the first pipe. The outer wall of the guide tube has a tapered portion. Four square through holes are symmetrically opened on the front surface of the second flange, and two slots are symmetrically opened on the inner wall of the square through holes. This utility model, through the combined use of the first flange, the second flange, and the fastening components, allows for quick connection of pipes without the use of external tools, avoiding the use of bolts for fixing, thereby reducing the workload of relevant personnel and improving the work efficiency of relevant personnel in disassembling and replacing pipes.

[0004] The common problem with the pipe connection device in the aforementioned patent and similar devices on the market is that there is no buffer time when the pipe leaks. When the pipe leaks, liquid water will drip immediately, making it inconvenient for maintenance personnel to locate the leak and making it impossible to repair it in time. Utility Model Content

[0005] To address the aforementioned issues, a water conservancy engineering pipeline connection device is provided. When a pipeline leaks, liquid water enters the inlet cylinder through the inlet hole. At this time, the lifting rod rises under pressure, causing the contact point to rise as it rises. When the contact point reaches a designated position, an alarm is triggered, causing liquid water to overflow from the inlet cylinder and flow into the storage cylinder. The water can be discharged through a valve inside the drain pipe. Furthermore, the device facilitates maintenance personnel to arrive for repairs while the storage cylinder is accumulating water.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy engineering pipeline connection device, comprising a first pipeline, a second pipeline, a sealing ring, a lower positioning plate, an upper positioning plate, a lifting rod, a contact point, and an alarm. The second pipeline is disposed at one end of the first pipeline. The sealing ring is disposed on the outside of the connection between the first pipeline and the second pipeline. The lower positioning plate is disposed at the connection between the first pipeline and the second pipeline and is located on the side of the sealing ring. The upper positioning plate is disposed above the lower positioning plate. The lifting rod is disposed above the upper positioning plate. The contact point is disposed above the lifting rod. The alarm point is disposed above the contact point.

[0007] Furthermore, the groove is formed on the inner wall of the lower positioning plate and the upper positioning plate, the groove matches the sealing ring, and water storage tanks are formed on both sides of the inner wall of the lower positioning plate located in the groove.

[0008] Furthermore, the lower positioning plate and the upper positioning plate are connected by a locking screw, and one end of the locking screw is provided with a nut.

[0009] Furthermore, a water inlet cylinder is provided on the top of the upper positioning plate, and a water inlet hole communicating with the water storage tank is opened on the top of the upper positioning plate, with the central axis of the water inlet cylinder and the water inlet hole coinciding.

[0010] Furthermore, a water storage cylinder is provided at the top center of the upper positioning plate, a cylinder cap is threaded onto the top of the water storage cylinder, a drain pipe is connected to one side of the water storage cylinder, and a valve is provided on the outside of the drain pipe.

[0011] Furthermore, a hollow tube is provided at the top of the upper positioning plate and inside the water storage tank. A telescopic rod is slidably installed inside the hollow tube. A load-bearing plate connected to the lifting rod is provided at the top of the telescopic rod, and a return spring is provided at the bottom of the telescopic rod and inside the hollow tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the water conservancy engineering pipeline connection device is reasonable and has the following advantages:

[0013] The sealing ring is placed on the outside of the connection between the first and second pipes. Then, the sealing ring is tightly fixed by the cooperation of the lower positioning plate and the upper positioning plate. This can enhance the sealing performance of the pipe connection. In case of leakage, liquid water will first enter the water storage tank and then enter the water inlet cylinder under the action of the water inlet hole. At this time, the lifting rod will rise under the action of pressure. During the lifting process, the lifting rod will drive the contact point to rise. When the contact point rises to the designated position, an alarm will be triggered.

[0014] Liquid water flows into the water storage tank and can be discharged through the valve inside the drain pipe. During the water storage tank's water filling process, it is convenient for maintenance personnel to come and repair the device. After the device is repaired, the telescopic rod will retract into the hollow tube under the action of the return spring. When the telescopic rod retracts, it will drive the load-bearing plate and the lifting rod to rise and fall. At this time, the lifting rod is reinserted into the water inlet tank to seal it, allowing the device to be reused and enhancing its environmental performance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to the following: Figures 1 to 5A water conservancy engineering pipeline connection device includes a first pipeline 1, a second pipeline 2, a sealing ring 3, a lower positioning plate 4, an upper positioning plate 5, a lifting rod 6, a contact 7, and an alarm 8. The second pipeline 2 is located at one end of the first pipeline 1. The sealing ring 3 is located on the outside of the connection between the first pipeline 1 and the second pipeline 2. The lower positioning plate 4 is located at the connection between the first pipeline 1 and the second pipeline 2 and is located on the side of the sealing ring 3. The upper positioning plate 5 is located above the lower positioning plate 4. The lifting rod 6 is located above the upper positioning plate 5. The contact 7 is located above the lifting rod 6. The alarm 8 is located above the contact 7.

[0023] The sealing ring 3 is placed on the outside of the connection between the first pipe 1 and the second pipe 2. Then, the sealing ring 3 is tightly fixed by the cooperation of the lower positioning plate 4 and the upper positioning plate 5, which can enhance the sealing performance of the pipe connection. When the pipe leaks, the lifting rod 6 moves upward under the action of water. When the lifting rod 6 is raised to a certain height, the contact 7 at the top of the lifting rod 6 will trigger the alarm 8. At this time, the staff will receive a prompt and go to the site for maintenance. The liquid water will be stored inside the device and will not leak. The device has a high safety performance.

[0024] like Figure 1 and Figure 5 As shown, the groove 9 is formed on the inner wall of the lower positioning plate 4 and the upper positioning plate 5. The groove 9 matches the sealing ring 3. Water storage tanks 11 are formed on both sides of the inner wall of the lower positioning plate 4 and located in the groove 9.

[0025] The sealing ring 3 can be installed through the groove 9. Under the action of the sealing ring 3, the sealing performance at the connection between the first pipe 1 and the second pipe 2 can be enhanced. In the event of a leak, liquid water will preferentially enter the water storage tank 11, which is convenient for entering the next unit and is used to warn the staff.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the lower positioning plate 4 and the upper positioning plate 5 are connected by a locking screw 10, and a nut 12 is provided at one end of the locking screw 10.

[0027] The locking screw 10 passes through the lower positioning plate 4 and the upper positioning plate 5. The locking screw 10 cooperates with the nut 12 to facilitate the sealing connection at the connection between the first pipe 1 and the second pipe 2.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, a water inlet cylinder 13 is provided on the top of the upper positioning plate 5, and a water inlet hole 14 connected to the water storage tank 11 is opened on the top of the upper positioning plate 5. The central axis of the water inlet cylinder 13 and the water inlet hole 14 coincide. A water storage cylinder 15 is provided at the center of the top of the upper positioning plate 5. A cylinder cover 16 is threaded on the top of the water storage cylinder 15. A drain pipe 17 is connected to one side of the water storage cylinder 15. A valve is provided on the outside of the drain pipe 17. A hollow tube 18 is provided on the top of the upper positioning plate 5 and inside the water storage cylinder 15. A telescopic rod 19 is slidably installed inside the hollow tube 18. A load-bearing plate 20 connected to the lifting rod 6 is provided on the top of the telescopic rod 19. A return spring is provided at the bottom of the telescopic rod 19 and inside the hollow tube 18.

[0029] By cooperating with the cap 16, the water storage cylinder 15 can maintain a sealed performance. When a leak occurs in the pipeline, liquid water will enter the water inlet cylinder 13 through the inlet hole 14. At this time, the lifting rod 6 will rise under pressure. During the rising process, the lifting rod 6 will drive the contact 7 to rise. When the contact 7 rises to the designated position, an alarm will be triggered. At this time, liquid water will overflow from the water inlet cylinder 13 and flow into the water storage cylinder 15. The water can be discharged through the valve inside the drain pipe 17. During the water storage process, it is convenient for maintenance personnel to come for maintenance. After the device is repaired, the telescopic rod 19 will retract into the hollow tube 18 under the action of the return spring. When the telescopic rod 19 retracts, it will drive the load-bearing plate 20 and the lifting rod 6 to rise and fall. At this time, the lifting rod 6 will re-insert into the water inlet cylinder 13 to seal it.

[0030] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but 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.
