Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a waterproof and drainage device for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Only by building water conservancy projects can water flow be controlled, floods be prevented, and water volume be regulated and distributed to meet the needs of people's lives and production for water resources. There are many kinds of equipment in water conservancy projects, among which the waterproof and drainage device for water conservancy project construction is one of them, mainly used for waterproofing and drainage.

[0003] A search revealed that Chinese Patent CN213625425U discloses a waterproofing and drainage device for water conservancy engineering construction. The device includes a housing with an opening at the top center. Two racks are symmetrically fixed to the left and right sides of the upper housing wall, each housing a filter. A first drain pipe is fixedly connected to the middle of the left housing wall, and an electrically controlled valve is located in the middle of the first drain pipe. A sensor is fixedly connected to the front of the upper housing wall, positioned in front of the two racks and not in contact with them. A second drain pipe is fixedly connected to the lower right housing wall. This waterproofing and drainage device for water conservancy engineering construction, through its filter, can filter and collect impurities in the water, facilitating water reuse. The sensor allows for timely adjustment of the drainage volume, improving the device's drainage efficiency.

[0004] The aforementioned patent also has the following shortcomings: In the prior art, a filter plate is used to filter impurities in the water, but the filtered impurities will remain on the filter plate, hindering the water from entering. At the same time, the impurities need to be cleaned regularly to prevent them from becoming too numerous and spreading on the filter plate, making it difficult for water to flow in. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of impurities needing to be cleaned regularly to prevent excessive impurities from being laid on the filter plate and making it difficult for water to flow in. Therefore, a waterproof drainage device for water conservancy engineering construction is proposed.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A waterproofing and drainage device for water conservancy engineering construction, comprising:

[0008] The drainage cylinder has multiple discharge ports that are equidistantly distributed around its central axis on its outer side.

[0009] A filter assembly, comprising an annular plate, a vertical shaft, a dome cover, multiple scrapers, and multiple ejector plates;

[0010] The drainage cylinder is equipped with a support mechanism for supporting the annular plate. The bottom of the annular plate is located above the bottom of the discharge port. The dome cover is set inside the annular plate and is coaxially fixed with the annular plate. Multiple through holes are opened on the outer side of the dome cover. A rotating hole is opened at the middle position of the top of the dome cover. The vertical shaft is rotatably installed in the rotating hole. One end of the scraper is fixed to the top of the vertical shaft. The scraper is in contact with the dome cover and is inclined on the dome cover. One end of multiple scrapers is fixed to one end of multiple push plates one-to-one. The push plates are in contact with the annular plate and are inclined on the annular surface of the annular plate.

[0011] The bottom annular surface of the circular plate is provided with a drive assembly that enables the vertical axis to rotate axially.

[0012] Based on the above technical solution, the present invention can be further improved as follows:

[0013] Furthermore, the top of the drainage cylinder is provided with an inlet pipe that is integral with and connected to it, and the inlet pipe is axially connected to the drainage cylinder.

[0014] Furthermore, a first connecting flange, coaxially arranged with the water inlet pipe, is welded and fixed to one end of the inlet pipe.

[0015] Furthermore, the bottom of the drainage cylinder is provided with a drainage pipe that is integral with and connected to it, and the drainage pipe is coaxial with the drainage pipe. One end of the drainage pipe is welded and fixed with a second connecting flange that is coaxial with it.

[0016] Furthermore, the driving component includes:

[0017] Waterproof motors, the housings of the two waterproof motors are fixed to the annular plate;

[0018] Two fixing plates, which are fixed to the annular plate;

[0019] The transmission rod has a circular hole on the outer side of the fixing plate, and both ends of the transmission rod are rotatably installed in the two circular holes respectively. The output shaft of the waterproof motor is coaxially fixed with the transmission rod.

[0020] The main bevel gear is fixed coaxially with the transmission rod.

[0021] The secondary bevel gear is fixed coaxially with the vertical shaft, and the primary bevel gear meshes with the secondary bevel gear.

[0022] Furthermore, the support mechanism includes:

[0023] A double-section telescopic cylinder, one end of which is fixed to a circular plate;

[0024] Multiple fixing blocks, one side of each fixing block is fixed inside the drainage cylinder, and the other end of each double-section telescopic cylinder is fixed one-to-one with the fixing blocks;

[0025] Multiple springs are respectively sleeved on a double-section telescopic cylinder, and the two ends of the springs are respectively fixed to a circular plate and a fixing block.

[0026] Furthermore, a cam is fixed to one end of the transmission rod, and a fixed shaft is rotatably mounted on the inner wall of the drainage cylinder. A contact wheel is fixed to one end of the fixed shaft and is coaxially arranged with it, and the contact wheel is in contact with the cam.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0028] 1. This utility model employs a filter assembly and a drive assembly. Wastewater flows in from the top of the drainage cylinder, passes through a dome cover, and the water in the wastewater flows into the bottom of the drainage cylinder through the through-holes in the dome cover. Fixed impurities in the wastewater cannot pass through the through-holes and are thus blocked. The drive assembly is activated, causing the vertical shaft to rotate axially. The vertical shaft drives the scraper to rotate on the upper surface of the dome cover. Because the scraper is inclined on the dome cover, it pushes the impurities on the dome cover towards the annular plate. Furthermore, because the push plate on the scraper is inclined on the annular plate, it pushes the impurities outwards. When passing through the discharge port, the fixed impurities are pushed out of the drainage cylinder. Therefore, this technical method effectively solves the technical problem in existing water conservancy engineering construction waterproof drainage devices that require regular cleaning of impurities to prevent excessive impurities from being laid on the filter plate and hindering water flow. This achieves the technical effect of a self-cleaning filter assembly.

[0029] 2. This utility model employs a drive assembly, a cam, and a contact wheel. Specifically, the waterproof motor rotates the transmission rod via its output shaft. As the transmission rod rotates, the cam on the transmission rod rotates, and the cam's protrusion continuously passes through the contact wheel, causing the annular plate to vibrate up and down. This vibrates out impurities blocking the through holes, facilitating subsequent scraping by the scraper. Therefore, this invention effectively solves the technical problem of impurities clogging the filter's through holes in existing waterproof drainage devices for water conservancy projects, thereby achieving a smoother filtration process.

[0036] 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.

[0037] Combination Figures 1-5 As shown, this utility model discloses a waterproofing and drainage device for water conservancy engineering construction, comprising:

[0038] The drainage cylinder 1 has multiple discharge ports 2 that are equidistantly distributed around its central axis in a ring shape.

[0039] The filter assembly 7 includes an annular plate 8, a vertical shaft 9, a dome cover 12, multiple scrapers 10, and multiple ejector plates 11.

[0040] The drainage cylinder 1 is equipped with a support mechanism for supporting the annular plate 8. The bottom of the annular plate 8 is located above the bottom of the discharge port 2. The dome cover 12 is set inside the ring of the annular plate 8 and is coaxially fixed with the annular plate 8. Multiple through holes 16 are opened on the outer side of the dome cover 12. A rotating hole is opened at the middle position of the top of the dome cover 12. The vertical shaft 9 is rotatably installed in the rotating hole. One end of the scraper 10 is fixed on the top of the vertical shaft 9. The scraper 10 is in contact with the dome cover 12 and is inclined on the dome cover 12. One end of multiple scrapers 10 is fixed one-to-one with one end of multiple push plates 11. The push plates 11 are in contact with the annular plate 8 and are inclined on the annular surface of the annular plate 8.

[0041] Among them, the bottom ring surface of the annular plate 8 is provided with a drive component that enables the vertical shaft 9 to rotate axially;

[0042] Based on the above connection relationship, the technical solution of this utility model is as follows: sewage flows in from the top of the drain cylinder 1, passes through the dome cover 12, and the water in the sewage flows into the bottom of the drain cylinder 1 through the through hole 16 of the dome cover 12. However, the fixed impurities in the sewage cannot pass through the through hole 16 and are thus blocked. The drive assembly is activated, and the drive assembly causes the vertical shaft 9 to rotate axially. The vertical shaft 9 drives the scraper 10 to rotate on the upper surface of the dome cover 12. Since the scraper 10 is inclined on the dome cover 12, the scraper 10 pushes the impurities on the dome cover 12 toward the annular plate 8. Since the push plate 11 on the scraper 10 is inclined on the annular surface of the annular plate 8, the push plate pushes the impurities to the outside. When passing through the discharge port 2, the fixed impurities are pushed out of the drain cylinder 1. Thus, it can be seen that the entire filter assembly 7 has a self-cleaning function and will not affect the filtration due to the accumulation of impurities.

[0043] Based on the above technical solution, the present invention can be further improved as follows:

[0044] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 As shown: The top of the drainage cylinder 1 is provided with an inlet pipe 3 that is integral with and connected to it, and the inlet pipe 3 is axially aligned with the drainage cylinder 1. Here is a supplementary explanation of the inlet pipe 3: the diameter of the inlet pipe 3 is smaller than the spherical diameter of the dome cover 12, so that water will not come into contact with the annular plate 8 during the downward flow of water. One end of the inlet pipe 3 is welded and fixed with a first connecting flange 4 that is coaxially aligned with it. The first connecting flange 4 is used to connect with an external water source pipe.

[0045] In a preferred embodiment, this utility model can be further configured as follows: Figure 2As shown: The bottom of the drainage cylinder 1 is provided with a drainage pipe 5 that is integral with and connected to it, and the drainage pipe 5 is coaxially arranged with the drainage. One end of the drainage pipe 5 is welded and fixed with a second connecting flange 6 that is coaxially arranged with it. The connecting flange is used to connect with an external water supply pipe.

[0046] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 As shown: The driver components include:

[0047] Waterproof motor 17 is existing technology, and its specific structure and working principle will not be described in detail here. The outer shells of the two waterproof motors 17 are fixed on the annular plate 8.

[0048] Two fixing plates 13 are fixed to the annular plate 8 (either by welding or by using fixing bolts);

[0049] The transmission rod 18 has a round hole on the outside of the fixing plate 13. The two ends of the transmission rod 18 are rotatably installed in the two round holes respectively. The output shaft of the waterproof motor 17 is coaxially fixed with the transmission rod 18. The waterproof motor 17 causes the transmission rod 18 to rotate through the output shaft.

[0050] The main bevel gear 19 is coaxially fixed with the transmission rod 18. When the transmission rod 18 rotates, the main bevel gear 19 rotates synchronously with the transmission rod 18.

[0051] The secondary bevel gear 20 is fixed coaxially with the vertical shaft 9, and the main bevel gear 19 meshes with the secondary bevel gear 20. When the main bevel gear 19 rotates, the main bevel gear 19 causes the vertical shaft 9 to rotate through the secondary bevel gear 20 meshing with it.

[0052] In a preferred embodiment, this utility model can be further configured as follows: Figure 3 , Figure 4 , Figure 5 As shown: The support structure includes:

[0053] Double-section telescopic cylinder 15, one end of which is fixed to the circular ring plate 8;

[0054] Multiple fixing blocks 24, one side of each fixing block 24 is fixed inside the drainage cylinder 1, and the other end of each double-section telescopic cylinder 15 is fixed one-to-one with each fixing block 24;

[0055] Multiple springs 14 are respectively sleeved on the double-section telescopic cylinder 15, and the two ends of the springs 14 are respectively fixed to the annular plate 8 and the fixing block 24.

[0056] One end of the transmission rod 18 is fixed with a cam 23, and a fixed shaft 21 is rotatably mounted on the inner wall of the drainage cylinder 1. One end of the fixed shaft 21 is fixed with a contact wheel 22 coaxially arranged with it, and the contact wheel 22 contacts the cam 23. When the transmission rod 18 rotates, the cam 23 on the transmission rod 18 rotates, and the protrusion of the cam 23 continuously passes through the contact wheel 22, thereby causing the annular plate 8 to vibrate up and down, shaking out the impurities blocked in the through hole 16, which is convenient for subsequent scraping by the scraper 10.

[0057] The specific working principle of this utility model's waterproofing and drainage device for water conservancy engineering construction is as follows:

[0058] Wastewater flows into the drain cylinder 1 from the top through the inlet pipe 3. The wastewater flows into the drain cylinder 1 from the top and passes through the dome cover 12. The water in the wastewater flows into the bottom of the drain cylinder 1 through the through hole 16 of the dome cover 12. Fixed impurities in the wastewater cannot pass through the through hole 16 and are thus blocked.

[0059] The waterproof motor 17 is started, and the waterproof motor 17 causes the transmission rod 18 to rotate through the output shaft. When the transmission rod 18 rotates, the main bevel gear 19 rotates synchronously with the transmission rod 18. When the main bevel gear 19 rotates, the main bevel gear 19 causes the vertical shaft 9 to rotate through the secondary bevel gear 20 that meshes with it. The vertical shaft 9 drives the scraper 10 to rotate on the upper surface of the dome cover 12. Since the scraper 10 is inclined on the dome cover 12, the scraper 10 pushes the impurities on the dome cover 12 toward the annular plate 8. Since the push plate 11 on the scraper 10 is inclined on the annular surface of the annular plate 8, the push plate pushes the impurities to the outside. When passing through the discharge port 2, the fixed impurities are pushed out of the drain cylinder 1.

[0060] The above process also includes the following processes:

[0061] When the transmission rod 18 rotates, the cam 23 on the transmission rod 18 rotates. The protrusion of the cam 23 continuously passes through the contact wheel 22, thereby causing the annular plate 8 to vibrate up and down, dislodging the impurities blocked in the through hole 16, which is convenient for subsequent scraping by the scraper 10.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
