Description

Technical Field

[0001] This utility model relates to the technical field of pipeline anti-blocking devices, and in particular to an anti-blocking device for pre-buried water conservancy pipelines. Background Technology

[0002] In water conservancy projects, it is usually necessary to pre-bury pipelines to form an underground pipeline network, so that the pipelines can be directly connected for transportation after completion. The anti-blocking device for pre-buried pipelines in water conservancy projects is a device specially designed to prevent the pre-buried pipelines from being blocked, thus avoiding the extension of the construction period due to pipeline blockage.

[0003] Chinese patent document CN212317094U discloses an anti-clogging device for pre-buried water conservancy pipelines, including a ground surface and a groove. A pre-buried groove is formed at the lower end of the ground surface. A first pipeline is installed at the left end of the pre-buried groove. A second pipeline is fixedly connected to the right end of the first pipeline via a connecting ring. A first interface and a second interface are respectively provided at the right end of the first pipeline and the left end of the second pipeline. This invention connects a sludge removal pipe to the lower ends of the first and second pipelines via the first and second interfaces, respectively. When sewage flows from the first pipeline to the second pipeline, it passes through a double-layer filter screen, blocking a large amount of impurities at the right end of the first pipeline and flowing into the sludge removal pipe. Thus, the first and second pipelines are impeded by impurities during sewage flow, effectively preventing blockage of the water conservancy pipeline. This makes it a more practical and widely applicable anti-clogging device for pre-buried water conservancy pipelines.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model uses a double-layer filter screen for filtration, the filter screen needs to be manually removed for cleaning during use, which is inefficient. In addition, the uneven distribution of water flow inside the pipe results in a low filtration effect. Utility Model Content

[0006] This utility model provides an anti-clogging device for pre-buried water conservancy pipelines to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A device for preventing blockage of a pre-buried water conservancy pipeline includes a pipe body, a support mechanism movably connected to the inner side of the pipe body, a filter plate slidably connected to the right side of the inner cavity of the pipe body, and a drive mechanism fixedly connected to the middle of the filter plate.

[0009] The driving mechanism includes a slide rod, the middle of the outer periphery of which is fixedly connected to the middle of the filter plate. A flow guide block is fixedly connected to the left end of the slide rod, and a compression spring is fixedly connected to the middle of the right side of the flow guide block.

[0010] Preferably, a limiting plate is fixedly connected to the right end of the slide rod, and a compression spring is movably sleeved on the outer periphery of the left side of the slide rod.

[0011] Preferably, the support mechanism includes a support plate, which is fixedly connected to the middle of the inner side of the tube. A baffle is fixedly connected to the right side of the inner side of the tube. Four connecting rods arranged in a ring are fixedly connected to the opposite side of the support plate and the baffle. A compression spring arranged in a ring is fixedly connected to the right side of the support plate. The filter plate is slidably connected to the outer periphery of the connecting rods.

[0012] Preferably, a support frame is fixedly connected to the middle of the inner side of both the support plate and the baffle, and the outer periphery of the slide rod is slidably connected to the middle of the support frame.

[0013] Preferably, the left part of the drainage block is conical.

[0014] Preferably, the second compression spring is movably sleeved on the outer periphery of the connecting rod, and the right end of the second compression spring is fixedly connected to the left side of the filter plate.

[0015] Preferably, the right end of the compression spring abuts against the left side of the left support frame.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] This utility model provides an anti-clogging device for pre-buried water conservancy pipelines. Through the cooperation of a diversion block, a sliding rod, a compression spring, a limiting plate, and a filter plate, the pressure of the water flow and the elasticity of the compression spring are used to make the filter plate reciprocate inside the pipeline. This enhances the relative motion between the water flow and the filter plate, promotes the flushing and dispersion of impurity particles, achieves self-cleaning of the filter plate, significantly improves filtration efficiency, reduces the accumulation of impurities on the filter plate, extends the service life of the filtration system, and reduces the frequency and cost of manual cleaning.

[0018] This utility model provides an anti-clogging device for pre-buried water conservancy pipelines. Through the cooperation of a support plate, baffle, support frame, connecting rod, compression spring, diversion block, sliding rod, and filter plate, the water flow intensity varies in different areas inside the pipeline. The sliding rod slides in the middle of the support frame. Through the reciprocating movement of the diversion block, the water flow is more evenly distributed inside the pipeline, improving filtration efficiency and enhancing the stability of the entire system. The compression spring ensures that the diversion block and filter plate can maintain a stable position and posture when subjected to water flow impact, further improving the reliability and durability of the system.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, an anti-blocking device for a pre-buried water conservancy pipeline includes a pipe body 1, a support mechanism 3 movably connected to the inner side of the pipe body 1, a filter plate 4 slidably connected to the right side of the inner cavity of the pipe body 1, and a drive mechanism 2 fixedly connected to the middle of the filter plate 4.

[0027] The drive mechanism 2 includes a slide bar 22. The middle part of the outer periphery of the slide bar 22 is fixedly connected to the middle part of the filter plate 4. A flow guide block 21 is fixedly connected to the left end of the slide bar 22, and a compression spring 23 is fixedly connected to the middle part of the right side of the flow guide block 21.

[0028] It should be noted that pipe body 1 is a pre-buried pipe, and filter plate 4 is used to filter the water flow. Drive mechanism 2 is used to move filter plate 4 by the pressure of water flow. Slide rod 22 is used to connect diversion block 21 and filter plate 4. Water flow presses against diversion block 21, thereby moving filter plate 4. Compression spring 23 returns diversion block 21 to its original position when the pressure decreases, and at the same time, it also returns filter plate 4 to its original position, thereby allowing filter plate 4 to reciprocate inside pipe body 1.

[0029] like Figure 5 As shown, the right end of the slide rod 22 is fixedly connected to the limit plate 24, and the compression spring 23 is movably sleeved on the outer periphery of the left side of the slide rod 22.

[0030] It should be noted that the limiting plate 24 ensures that the movement range of the slide rod 22 within the pipe body 1 is restricted, preventing excessive movement that could lead to structural damage. Meanwhile, the compression spring 23, movably sleeved on the slide rod 22, provides stable elastic force, ensuring the stability of the diversion block 21 and the filter plate 4 when subjected to water flow impact.

[0031] like Figure 3 As shown, the support mechanism 3 includes a support plate 31, which is fixedly connected to the middle of the inner side of the tube body 1. A baffle 32 is fixedly connected to the right side of the inner side of the tube body 1. Four connecting rods 33 arranged in a ring are fixedly connected to the opposite side of the support plate 31 and the baffle 32. A compression spring 34 arranged in a ring is fixedly connected to the right side of the support plate 31. The filter plate 4 is slidably connected to the outer periphery of the connecting rods 33.

[0032] It should be noted that the support mechanism 3, through the support plate 31, baffle 32, and connecting rod 33, provides a stable sliding track for the filter plate 4, ensuring the smooth movement of the filter plate 4 within the pipe body 1. Simultaneously, the compression spring 34 provides additional support force when the filter plate 4 is subjected to water flow impact, preventing damage due to excessive pressure.

[0033] like Figure 3 As shown, a support frame 35 is fixedly connected to the middle of the inner side of the support plate 31 and the baffle 32, and the outer periphery of the slide rod 22 is slidably connected to the middle of the support frame 35.

[0034] It should be noted that the design of the support frame 35 provides a more stable sliding track for the slide rod 22, ensuring the stability and accuracy of the slide rod 22 when subjected to water flow impact. At the same time, the support frame 35 also prevents the slide rod 22 from deviating from the track during movement, thus preventing structural damage.

[0035] like Figure 2 As shown, the left part of the drainage block 21 is conical.

[0036] It should be noted that the conical guide block 21 can more effectively guide the water flow, making the water flow more evenly distributed on the filter plate 4, thereby improving the filtration efficiency. At the same time, the conical design can also reduce the impact force of the water flow on the guide block 21, extending its service life.

[0037] like Figure 4 As shown, compression spring 2 34 is movably sleeved on the outer periphery of connecting rod 33, and the right end of compression spring 2 34 is fixedly connected to the left side of filter plate 4.

[0038] It should be noted that the compression spring 34 is movably sleeved on the connecting rod 33, providing stable elastic support for the filter plate 4 and preventing it from moving excessively due to water flow impact. Simultaneously, the right end of the compression spring 34 is fixedly connected to the filter plate 4, ensuring that the filter plate 4 returns to its original position after the pressure is released.

[0039] like Figure 5 As shown, the right end of the compression spring 23 abuts against the left side of the left support frame 35.

[0040] It should be noted that the compression spring 23 abuts against the left side of the support frame 35 to limit the leftward movement of the slide bar 22 and the filter plate 4, preventing damage to the device due to excessive movement.

[0041] The working principle of this utility model is as follows: First, the pressure of the water flow inside the pipe changes every moment, which also changes the pressure on the diversion block 21 and the filter plate 4. The compression spring 24 provides elasticity so that the filter plate 4 can return to its original position when the pressure decreases. The compression spring 123 also provides elasticity so that the diversion block 21 can return to its original position. Therefore, the filter plate 4 moves back and forth inside the pipe body 1. The impurities on its surface are subjected to additional scouring force, making them easier to remove, thus enabling the filter plate 4 to achieve self-cleaning. The reciprocating movement of the filter plate 4 also drives the reciprocating movement of the diversion block 21, which disturbs the water flow inside the pipe body 1, making the water flow inside the pipe more evenly distributed inside the pipe, promoting the dispersion and suspension of impurity particles in the water flow, and reducing the particulate matter attached to the surface of the filter plate 4.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
