Description

Technical Field

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

[0002] Water pipelines are mainly used in water conservancy projects to transport water resources and ensure the normal operation of water conservancy facilities. They are classified into various types according to different uses and operating conditions, such as drainage pipelines and irrigation pipelines.

[0003] Existing irrigation pipes require water intake, and impurities easily accumulate inside. Cleaning these impurities is cumbersome. Simply adding a filter screen inside the pipe, as described in application number 202321405324.4, results in leakage between the valve and the filter element during filter replacement, even with a valve. This leads to poor performance. Therefore, an improved irrigation pipe design is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a water conservancy pipeline to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy pipeline, including an inlet pipe, an outlet pipe provided on one side of the inlet pipe, and a filter mechanism for filtering impurities provided between the inlet pipe and the outlet pipe. The filter mechanism includes a filter pipe, a filter element, a sealing ring, a sealing piston, a temporary storage tube, a screw, and a threaded sleeve. The filter pipe is fixedly provided between the inlet pipe and the outlet pipe. The filter element is provided inside the filter pipe. A sealing ring is fixedly provided at the lower end of the filter element. A sealing piston is provided at the upper end of the filter element. A temporary storage tube is fixedly provided at the lower end of the filter pipe. A screw is fixedly provided in the middle of the inner side of the sealing piston. A threaded sleeve is movably provided at the upper end of the filter pipe through a bearing.

[0006] Preferably, the threaded sleeve is movably fitted onto the outer surface of the screw via threads. By rotating the threaded sleeve, the screw, sealing piston, and filter element can be driven to move downwards under the action of the threads until a certain position is formed. Figure 4 As shown in the diagram, the sealing piston blocks both the inlet and outlet pipes, and the filter element is located inside the temporary storage tube. At this point, the operator can open the sealing cover through the flange to easily clean the impurities inside the filter element and the temporary storage tube. Since the sealing piston blocks both the inlet and outlet pipes, there is no need to worry about leakage.

[0007] Preferably, a fixing rod is fixedly provided on both sides of the lower end of the sealing piston. The fixing rod passes through the filter element and extends into the interior of the filter element. A fixing screw is provided on the outer surface of the fixing rod by means of a threaded screw. The filter element and the sealing piston are fixed together by the fixing screw. In this way, when it is necessary to disassemble and replace the new filter element, only the fixing screw needs to be removed, making the filter element replacement work of the device convenient and quick.

[0008] Preferably, a sealing cover is fixedly installed at the lower end of the temporary storage tube via a connecting flange. The sealing cover is made of elastic metal material, allowing filtered impurities to settle inside the temporary storage tube. When needed, the connecting flange can be opened to remove the sealing cover, and the remaining small amount of water inside the temporary storage tube can flush out any remaining waste. This allows for quick discharge of filtered waste. The elastic metal material sealing cover ensures sufficient structural strength while also providing some deformation buffering.

[0009] Preferably, a handwheel is fixedly provided at the upper end of the threaded sleeve. The threaded sleeve can be easily rotated by the handwheel, thereby driving the screw, sealing piston and filter element to move downward under the action of the thread.

[0010] Preferably, a limiting sleeve is fixedly provided on one side of the sealing piston, and a limiting rod is fixedly provided on one side of the upper end of the filter tube. The limiting sleeve is movably sleeved inside the limiting rod. The rotation of the sealing piston is restricted by the limiting rod and the inside of the limiting sleeve, thereby preventing the sealing piston from rotating together when the threaded sleeve rotates, which would prevent the sealing piston from moving up and down.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the filter element needs to be cleaned, the operator can turn the handwheel and threaded sleeve, and then drive the screw, sealing piston, and filter element to move down, so that the sealing piston blocks both the inlet and outlet pipes. Since the sealing piston blocks both the inlet and outlet pipes, there is no need to worry about water leakage when disassembling the filter element during subsequent maintenance. This device will only leak a small amount of water from the storage tube, and this water is just enough to flush out impurities. In addition, this device is equivalent to a two-way valve when in use, so there is no need to install a valve in both the inlet and outlet pipes.

[0013] 2. When cleaning this utility model, the filter element is exactly inside the temporary storage tube. At this time, the staff can open the sealing cover through the flange. Then, the small amount of water remaining inside the temporary storage tube can flush out the residual garbage inside the temporary storage tube. At this time, the staff can easily touch the inside of the filter element to clean the impurities inside the filter element and the impurities inside the temporary storage tube, or replace the filter element.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a water conservancy pipeline, including an inlet pipe 1, an outlet pipe 2 provided on one side of the inlet pipe 1, and a filter mechanism for filtering impurities provided between the inlet pipe 1 and the outlet pipe 2. The filter mechanism includes a filter pipe 3, a filter element 4, a sealing ring 5, a sealing piston 6, a temporary storage pipe 7, a screw 8, and a threaded sleeve 9. The filter pipe 3 is fixedly provided between the inlet pipe 1 and the outlet pipe 2. The filter element 4 is provided inside the filter pipe 3. The sealing ring 5 is fixedly provided at the lower end of the filter element 4. The sealing piston 6 is provided at the upper end of the filter element 4. The temporary storage pipe 7 is fixedly provided at the lower end of the filter pipe 3. The screw 8 is fixedly provided in the middle of the inner side of the sealing piston 6. The threaded sleeve 9 is movably provided at the upper end of the filter pipe 3 through a bearing.

[0022] The threaded sleeve 9 is movably fitted onto the outer surface of the screw 8 via threads. By rotating the threaded sleeve 9, the screw 8, sealing piston 6, and filter element 4 can be driven downwards by the threads until a certain position is formed. Figure 4 As shown, the sealing piston 6 blocks both the inlet pipe 1 and the outlet pipe 2, and the filter element 4 is also inside the temporary storage tube 7. At this time, the staff can open the sealing cover 12 through the flange to easily clean the impurities inside the filter element 4 and the temporary storage tube 7. Since the sealing piston 6 blocks both the inlet pipe 1 and the outlet pipe 2, there is no need to worry about water leakage.

[0023] The sealing piston 6 has a fixing rod 10 fixedly installed on both sides of its lower end. The fixing rod 10 passes through the filter element 4 and extends into the filter element 4. The outer surface of the fixing rod 10 is provided with a fixing screw 11 by threaded engagement. The filter element 4 and the sealing piston 6 are fixed together by the fixing screw 11. In this way, when it is necessary to disassemble and replace the new filter element 4, only the fixing screw 11 needs to be removed, making the replacement of the filter element 4 of the device convenient and quick.

[0024] The lower end of the temporary storage tube 7 is fixed with a sealing cover 12 via a connecting flange. The sealing cover 12 is made of elastic metal material. The filtered impurities can be deposited inside the temporary storage tube 7. When needed, the connecting flange can be opened to remove the sealing cover 12. Then, the remaining small amount of water inside the temporary storage tube 7 can flush out the remaining waste inside the temporary storage tube 7. This can quickly complete the discharge of filtered waste. The sealing cover 12, made of elastic metal material, can ensure sufficient structural strength while also providing a certain degree of deformation buffer.

[0025] A handwheel 13 is fixedly provided at the upper end of the threaded sleeve 9. The threaded sleeve 9 can be easily rotated by the handwheel 13, thereby driving the screw 8, sealing piston 6 and filter element 4 to move downward under the action of the thread.

[0026] A limiting sleeve 14 is fixedly provided on one side of the sealing piston 6, and a limiting rod 15 is fixedly provided on one side of the upper end of the filter tube 3. The limiting sleeve 14 is movably sleeved inside the limiting rod 15. The sealing piston 6 is restricted from rotating by the limiting rod 15 and the limiting sleeve 14, so as to prevent the sealing piston 6 from rotating together when the threaded sleeve 9 rotates, which would prevent the sealing piston 6 from moving up and down.

[0027] Working Principle: The filtration principle of this device is as follows: Water from the inlet pipe enters the filter pipe 3, then enters the filter element 4, passes through the holes in the filter element 4 to the outside of the filter element 4, and then enters the outlet pipe 2. Thus, the filter element 4 filters impurities from the water, trapping them inside. When the water flow is not flowing and there is no irrigation need, some impurities will settle inside the temporary storage pipe 7 under gravity, while others will become stuck in the inner sidewall of the filter element 4. When cleaning the filter element 4 is required, the operator can turn the handwheel 13 and the threaded sleeve 9, which will drive the screw 8 and the sealing piston 6, causing the filter element 4 to move downwards until a... Figure 4 As shown in the diagram, the sealing piston 6 blocks both the inlet pipe 1 and the outlet pipe 2. Since the sealing piston 6 blocks both the inlet pipe 1 and the outlet pipe 2, there is no need to worry about leakage when disassembling the filter element 4 during subsequent maintenance.

[0028] At this time, the filter element 4 is inside the temporary storage tube 7. At this time, the staff can open the sealing cover 12 through the flange. Then, the remaining small amount of water inside the temporary storage tube 7 can flush out the residual garbage inside the temporary storage tube 7. At this time, the staff can easily touch the inside of the filter element 4 to clean the impurities inside the filter element 4 and the impurities inside the temporary storage tube 7.

[0029] Furthermore, this device functions as a two-way valve during use, eliminating the need to install valves in both the inlet pipe 1 and the outlet pipe 2.

[0030] When cleaning filter element 4 in this device, it is necessary to shut off the upstream water supply, that is, to close the valve at the inlet pipe 1 to stop the water supply.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
