Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction, and in particular to a pipe connection component for water conservancy engineering construction. Background Technology

[0002] In water conservancy engineering construction, the performance of pipeline connection components directly affects water conveyance efficiency, system stability, and maintenance costs. At present, traditional pipeline connection technologies have obvious limitations. On the one hand, although commonly used flange connections, welding, or threaded connections can fix the pipeline, the installation process relies on bolt tightening, welding equipment, and professional technicians. The operation is cumbersome and time-consuming, making it difficult to meet the needs of rapid installation in emergency rescue, temporary construction, and other scenarios. At the same time, the sealing of these connection structures is greatly affected by human operation. Long-term operation is prone to loosening due to water flow impact and foundation settlement, posing a risk of leakage. In particular, the reliability is insufficient under high pressure and vibration environments.

[0003] On the other hand, existing pipe connection components generally lack internal cleaning functions. During the water conveyance process of water conservancy projects, sediments such as silt, scale, and algae tend to accumulate inside the pipes, leading to a reduction in the pipe flow area, a decrease in water conveyance efficiency, and even blockages. Traditional cleaning methods rely on manual periodic disassembly of the pipes or high-pressure flushing. In addition, although some projects have attempted to add cleaning devices to the pipes, they are not integrated with the connection structure, resulting in complex installation and difficult maintenance, making it difficult to effectively promote and apply them. Therefore, the development of pipe connection components that combine quick snap-fit ​​connection and internal cleaning functions has become a key technical requirement for improving the construction efficiency and system reliability of water conservancy projects. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a pipe connection component for water conservancy engineering construction that can solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipe connection assembly for water conservancy engineering construction, comprising an inlet pipe, a connecting pipe fixedly connected to one end of the inlet pipe, an outlet pipe fixedly connected to one end of the connecting pipe, a fixed rod fixedly connected inside the connecting pipe, a rotating rod fixedly connected to one end of the fixed rod, and fan blades arrayed on the rotating rod;

[0006] A cleaning plate is fixedly connected to one end of the rotating rod, a filter screen is fixedly connected inside the connecting pipe, a drain pipe is fixedly connected to the bottom of the connecting pipe, a drain valve is threaded to one end of the drain pipe, the cleaning plate and the filter screen are in contact with each other, and the drain pipe passes through the bottom of the connecting pipe.

[0007] Preferably, one end of the inlet pipe and the outlet pipe are respectively fixedly connected to a fixing block, and a sliding rod is slidably connected to the fixing block. The sliding rod extends into the interior of the fixing block, and a spring is provided on the sliding rod. The two ends of the spring are respectively fixedly connected to the inner wall of the fixing block and the surface of the sliding rod.

[0008] Preferably, each end of the connecting tube is fixedly connected to a connecting rod, a movable rod is slidably connected inside the connecting rod, and a slider is slidably connected on the movable rod.

[0009] Preferably, the fixing block has a groove, the slider is annular, one end of the moving rod is hemispherical, and the hemispherical end is inclined and fits with one end of the slider.

[0010] Preferably, the fan blades are evenly distributed in an array on the rotating rod, and the number of fan blades is at least three.

[0011] Preferably, when the spring is in its natural state, the length of the sliding rod extending beyond the fixed block is not less than one-third of the length of the fixed block itself.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The pipeline connection components used in this water conservancy project have a unique feature: when the filter screen becomes clogged with impurities and needs cleaning, water flows in from the inlet pipe. The high-speed flow impacts the fan blades, causing them to rotate. This rotation, in turn, drives the cleaning blades to clean the surface of the filter screen. The removed impurities fall into the drain pipe due to their own weight. Therefore, the drain valve is periodically opened to remove impurities, allowing water to flow through the connection pipe and then through the outlet pipe. Simultaneously, the cleaning blades mechanically scrape away the deposits, breaking down their adhesion to the filter screen and maintaining the pipe's flow area. This cleaning process avoids the need for traditional manual water outages for maintenance. The cleaning not only ensures water delivery efficiency but also achieves extended benefits such as reduced wear, less maintenance, and improved water quality, thus controlling costs throughout the entire lifecycle.

[0014] This water conservancy project uses a pipe connection assembly. When pipes need to be connected and fixed, a movable rod is inserted into the fixed block, causing a sliding rod to engage between the movable rod and the slider, thus fixing the pipes. Simultaneously, pressing the other end of the movable rod causes it to move inwards towards the fixed block. The sliding rod then slides on one end of the slider, moving to the other end. Pulling the other end of the movable rod with external force causes the sliding rod to move the slider, eventually sliding to the other end of the movable rod, thus disconnecting the pipes. The snap-fit ​​structure, through mechanical engagement, eliminates the need for bolt tightening, welding preheating, and other cumbersome procedures. Disassembly only requires loosening the snap-fit ​​lock, without damaging the interface structure, facilitating pipe cleaning, sealing ring replacement, and other maintenance work. Compared to traditional flange connections and welding, the snap-fit ​​connection, with its unique design and high efficiency, effectively solves problems related to construction efficiency and maintenance costs.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a pipe connection assembly for water conservancy engineering construction, including an inlet pipe 1, a connecting pipe 2 fixedly connected to one end of the inlet pipe 1, an outlet pipe 3 fixedly connected to one end of the connecting pipe 2, and a fixing rod 7 fixedly connected inside the connecting pipe 2.

[0027] A rotating rod 8 is fixedly connected to one end of the fixed rod 7. Fan blades 6 are arranged on the rotating rod 8. A cleaning plate 9 is fixedly connected to one end of the rotating rod 8. A filter screen 10 is fixedly connected inside the connecting pipe 2. A drain pipe 11 is fixedly connected to the bottom of the connecting pipe 2. A drain door 12 is threadedly connected to one end of the drain pipe 11.

[0028] The cleaning plate 9 is attached to the surface of the filter screen 10, and the drain pipe 11 passes through the bottom of the connecting pipe 2;

[0029] When the filter screen 10 is clogged with impurities and needs to be cleaned in the connecting pipe 2, water flows in from the inlet pipe 1. The high-speed water flow impacts the fan blade 6, which drives the fan blade 6 to rotate the rotating rod 8. The rotating rod 8 then drives the cleaning plate 9 to clean the surface of the filter screen 10. The impurities that are cleaned fall into the drain pipe 11 due to their own gravity. Therefore, the drain door 12 is opened periodically to clean the impurities, and then the water flows through the connecting pipe 2 and the outlet pipe 3.

[0030] Meanwhile, the cleaning plate 9 mechanically scrapes away the deposits, breaking their attachment to the filter screen 10 and maintaining the flow area of ​​the pipe. The cleaning plate 9 cleans the filter screen 10, avoiding the need for traditional manual water outage maintenance. The cleaning plate 9 cleans the filter screen 10, not only ensuring water delivery efficiency, but also achieving full life cycle cost control by reducing wear, reducing maintenance, and optimizing water quality.

[0031] Furthermore, a fixing block 4 is fixedly connected to one end of the water inlet pipe 1 and the water outlet pipe 3 respectively. A sliding rod 15 is slidably connected to the fixing block 4. The sliding rod 15 extends into the interior of the fixing block 4. A spring 16 is provided on the sliding rod 15. The two ends of the spring 16 are fixedly connected to the inner wall of the fixing block 4 and the surface of the sliding rod 15 respectively.

[0032] Furthermore, connecting rods 5 are fixedly connected to both ends of the connecting tube 2, and a movable rod 13 is slidably connected inside the connecting rod 5, and a slider 14 is slidably connected on the movable rod 13;

[0033] The fixed block 4 has a groove, the slider 14 is annular, one end of the moving rod 13 is hemispherical, and the hemispherical end is inclined and fits with one end of the slider 14. The other end of the moving rod 13 is semi-cylindrical.

[0034] When it is necessary to connect and fix the pipes, the moving rod 13 is inserted into the inside of the fixing block 4, so the sliding rod 15 is locked between the moving rod 13 and the slider 14, thereby achieving the fixation between the pipes;

[0035] At the same time, press the other end of the moving rod 13. The moving rod 13 is forced to move into the fixed block 4. At this time, the sliding rod 15 slides on the surface of one end of the slider 14. Then the sliding rod 15 moves to the other end of the slider 14. Therefore, by pulling the other end of the moving rod 13 by external force, the sliding rod 15 drives the slider 14 to move, and then the sliding rod 15 slides to one end of the moving rod 13, thus realizing the disconnection between the pipes.

[0036] Furthermore, the snap-fit ​​structure uses mechanical interlocking, eliminating the need for cumbersome procedures such as bolt tightening and welding preheating. Disassembly only requires loosening the snap-fit ​​lock without damaging the interface structure, facilitating maintenance operations such as pipe cleaning and sealing ring replacement. Compared with traditional flange connections and welding methods, the snap-fit ​​connection effectively solves problems such as construction efficiency and operation and maintenance costs due to its unique design and high efficiency.

[0037] Working principle: When the filter screen 10 is clogged with impurities and needs to be cleaned in the connecting pipe 2, water flows in from the inlet pipe 1. The high-speed water flow impacts the fan blade 6, which drives the fan blade 6 to rotate the rotating rod 8. The rotating rod 8 then drives the cleaning plate 9 to clean the surface of the filter screen 10. The impurities that are cleaned fall into the drain pipe 11 due to their own gravity. Therefore, the drain door 12 is opened periodically to clean the impurities, and then the water flows through the connecting pipe 2 and the outlet pipe 3.

[0038] Meanwhile, the cleaning plate 9 mechanically scrapes away the deposits, breaking their attachment to the filter screen 10 and maintaining the flow area of ​​the pipe. The cleaning plate 9 cleans the filter screen 10, avoiding the need for traditional manual water outage maintenance. The cleaning plate 9 cleans the filter screen 10, not only ensuring water delivery efficiency, but also achieving full life cycle cost control by reducing wear, reducing maintenance, and optimizing water quality.

[0039] When it is necessary to connect and fix the pipes, the moving rod 13 is inserted into the inside of the fixing block 4, so the sliding rod 15 is locked between the moving rod 13 and the slider 14, thereby achieving the fixation between the pipes;

[0040] At the same time, press the other end of the moving rod 13. The moving rod 13 is forced to move into the fixed block 4. At this time, the sliding rod 15 slides on the surface of one end of the slider 14. Then the sliding rod 15 moves to the other end of the slider 14. Therefore, by pulling the other end of the moving rod 13 by external force, the sliding rod 15 drives the slider 14 to move, and then the sliding rod 15 slides to one end of the moving rod 13, thus realizing the disconnection between the pipes.

[0041] Furthermore, the snap-fit ​​structure uses mechanical interlocking, eliminating the need for cumbersome procedures such as bolt tightening and welding preheating. Disassembly only requires loosening the snap-fit ​​lock without damaging the interface structure, facilitating maintenance operations such as pipe cleaning and sealing ring replacement. Compared with traditional flange connections and welding methods, the snap-fit ​​connection effectively solves problems such as construction efficiency and operation and maintenance costs due to its unique design and high efficiency.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
