Description

Technical Field

[0001] The invention relates to the technical field of pressure-resistant and wear-resistant water pipes, in particular to a pressure-resistant and wear-resistant water pipe. Background Art

[0002] Water pipes are pipes for water supply. According to the materials, they can be divided into metal pipes, plastic-coated metal pipes, plastic pipes, etc. Metal pipes have the advantages of no rust and long service life, but they are expensive and the connection method is not as convenient as plastic pipes. Plastic-coated metal pipes are metal pipes with another layer of plastic wrapped outside. Such pipes are more durable than metal pipes, but they are prone to cracking and aging. Plastic pipes are light and easy to install, but their service life is not as long as metal pipes. Water pipes can also be divided into water supply pipes and drainage pipes for different purposes. During the use of water pipes, regular maintenance and inspection are required to ensure their normal operation;

[0003] In the chemical industry, different chemical products are easily mixed in the drainage pipe to produce different particle sediments. These particle sediments are easy to contact with the inner wall of the pipe and collide and rub when flowing with water in the pipe, especially at the bends of the water pipe, which is more prone to wear. When water flows through the bend, it will generate a large centrifugal force, which will cause the pipe wall to bear greater pressure. In addition, the particle sediments constantly collide and rub with the inner wall of the bend of the water pipe, thereby accelerating the wear of the pipe wall. After a period of time, the bend of the water pipe is prone to leakage, which may cause the chemical products in the pipe to leak, bringing certain safety hazards. For this reason, we propose a pressure-resistant and wear-resistant water pipe. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-10The present invention provides a technical solution: a pressure-resistant and wear-resistant water pipe, comprising an inner pipe 1, a plurality of buffer plates 4 are fixedly installed in the inner pipe 1, the buffer plates 4 are arranged in an inclined shape and cross-arranged, and a plurality of water filtering holes 5 are arranged on each buffer plate 4. When the water flow in the inner pipe 1 flows through the buffer plates 4, since the inclination direction of the buffer plates 4 is opposite to the direction of the water flow, a part of the water flow is blocked, thereby slowing down the flow rate and pressure of the water, and reducing the wear on the bending part of the inner pipe 1. A pressure-resistant pipe 2 is arranged outside the inner pipe 1, and a plurality of elastic blocks 3 are fixedly installed on the inner wall of the pressure-resistant pipe 2. One end of each elastic block 3 is fixedly connected to the outer wall of the inner pipe 1. When the inner pipe 1 is subjected to a large pressure and When deformation and expansion occur, the pressure-resistant tube 2 provides a resistance, so that the elastic block 3 is compressed and deformed, and at the same time, an inward thrust is given to the inner tube 1 to prevent the pressure in the inner tube 1 from increasing and expanding and being damaged. A fixing frame 6 is fixedly installed on the inner wall of the inner tube 1, and a rotating shaft 7 is rotatably installed on the fixing frame 6. A propeller 8 is fixedly installed on the rotating shaft 7. A rotating ring 9 is fixedly installed at one end of the rotating shaft 7. A plurality of arc blocks 10 are fixedly installed on the rotating ring 9. The arc blocks 10 are arranged in a circular arrangement, and the number thereof is an integer multiple of four. When water flows through the propeller 8, it will drive the propeller 8 to rotate, and the propeller 8 drives the rotating shaft 7 and the rotating ring 9 to rotate, and at the same time, the arc blocks 10 also perform circular motion;

[0034] A filter disc 11 is fixedly installed on the inner wall of the inner tube 1, and an elastic membrane 16 is fixedly installed on the inner walls around the filter disc 11. A first filter layer 33 and a second filter layer 34 are arranged in the filter disc 11. The first filter layer 33 includes a plurality of first fixed bars 21 and a plurality of first sliding bars 22. The first fixed bars 21 correspond to the first sliding bars 22 one by one and are arranged in a longitudinal cross arrangement. The inclined surfaces on both sides of each first fixed bar 21 form a first filter groove 31 with the inclined surfaces of two adjacent first sliding bars 22. Both ends of each first fixed bar 21 and both ends of each first sliding bar 22 penetrate the corresponding elastic membrane 16. Both ends of each first sliding bar 22 are fixedly installed with a first connecting block 20. Two first sliding columns 12 are slidably installed on the filter disc 11. One end of each first sliding column 12 is fixedly installed with a first connecting plate 14. One end of each first connecting block 20 is fixedly connected to the corresponding first connecting plate 14. The second filter layer 34 includes a plurality of second fixed bars 23 and a plurality of second sliding bars 24. The second filter layer 34 includes a plurality of second fixed bars 23 and a plurality of second sliding bars 24. The fixed bars 23 correspond to the second sliding bars 24 one by one and are arranged to be cross-arranged in a transverse manner. The inclined surfaces on both sides of each second fixed bar 23 and the inclined surfaces of two adjacent second sliding bars 24 form a second filter slot 32. Both ends of each second fixed bar 23 and both ends of each second sliding bar 24 penetrate the corresponding elastic membrane 16. Both ends of each second sliding bar 24 are fixedly installed with a second connecting block 26. Two second sliding posts 13 are slidably installed on the filter disc 11. One end of each second sliding post 13 is fixedly installed with a second connecting plate 15. One end of each second connecting block 26 is fixedly connected to the corresponding second connecting plate 15. The width of the first filter slot 31 is greater than that of the second filter slot 32, and both are arranged in a wedge shape to facilitate the entry of particle sediments. When water flows through the filter disc 11, larger particle sediments in the water flow will be intercepted by the first filter layer 33 and collected in the first filter slot 31, and smaller particle sediments in the water flow will be intercepted by the second filter layer 34 and collected in the second filter slot 32.

[0035] During the rotation of the rotating ring 9, the arc block 10 on it will be driven to push the first slide post 12 and the second slide post 13. Since the number of the arc blocks 10 is an integer multiple of four, the rotating ring 9 will repeatedly drive the four arc blocks 10 on it to push the two first slide posts 12 and the two second slide posts 13 at the same time. The two first slide posts 12 will drive the corresponding first connecting plates 14 and the corresponding first connecting blocks 20 to move, and make all the first sliding bars 22 move backward, so that the width of all the first filter slots 31 will increase. The two second sliding posts 13 will drive the corresponding second connecting plates 15 and the corresponding second connecting blocks 26 to move, and make all the second sliding bars 24 move backward, so that the width of all the second filter slots 32 will increase. A plurality of elastic plates 25 are fixedly installed in the filter disc 11, which are used to assist the first sliding bar 22 and the second sliding bar 24 to reset, so that the first sliding bar 12 and the second sliding bar 13 are reset, so that the arc block 10 can push them again;

[0036] A plurality of upper scrapers 28 and a plurality of lower scrapers 29 are fixedly mounted on each first sliding bar 22. Each upper scraper 28 and each lower scraper 29 are made of elastic material and correspond to the second filter slots 32 one by one. Both sides of each second fixed bar 23 are fixedly mounted with convex strips 27 for assisting the deformation of the upper scrapers 28 and the lower scrapers 29. Each upper scraper 28 and each lower scraper 29 are arranged to be arc-shaped on one side and straight on the other side. The straight surface of each upper scraper 28 is tightly attached to the straight surface of the corresponding lower scraper 29, and one end of each upper scraper 28 and one end of each lower scraper 29 are attached to the corresponding convex strip 27. During the movement of the first sliding bar 22, the corresponding upper scraper 28 and the lower scraper 29 will be driven to move synchronously, and the upper scraper 28 and the lower scraper 29 will be flexed by the convex strips 27. 8 and the limit of the end of the lower scraper 29, the end of the upper scraper 28 will move upward in an arc shape to scrape the particle sediment in the corresponding area of ​​the second filter tank 32 outward along the arc, and the end of the lower scraper 29 will move downward in an arc shape to scrape the particle sediment in the corresponding area of ​​the second filter tank 32 outward along the arc, and the second sliding bar 24 will also move backward at the same time, so that the width of the second filter tank 32 becomes larger, reducing the friction between the particle sediment and the two sides of the second filter tank 32 during the scraping process, and at the same time, the particle sediment in the second filter tank 32 is intercepted by the convex strip 27, so that the upper scraper 28 and the lower scraper 29 can scrape the particle sediment, and finally fall into the first filter layer 33 and the second filter layer 34. When the first sliding bar 22 is reset, it will drive the upper scraper The upper scraper 28 and the lower scraper 29 are reset by their own elasticity. A plurality of transverse scrapers 30 are fixedly installed on each second sliding bar 24. Each transverse scraper 30 is made of elastic material and corresponds to the first filter tank 31 one by one. Both sides of each transverse scraper 30 are set to symmetrical arcs, and one end thereof is also set to an arc. When the second sliding bar 24 moves backward, it will drive the corresponding transverse scraper 30 to move backward. When the particle sediment in the water enters the first filter tank 31, it is limited by the arc surface at the end of the transverse scraper 30, so that a part of it enters between the two transverse scrapers 30, and a part of it enters the arc-shaped scraping area of ​​the transverse scraper 30. During the backward scraping process of the transverse scraper 30, a part of the particles The sediment is scraped to between the first filter layer 33 and the second filter layer 34. At the same time, due to the backward movement of the first sliding bar 22, the width of the first filter slot 31 becomes larger, which reduces the friction between the particle sediment and the two sides of the first filter slot 31, making it easier for the transverse scraper 30 to scrape. At the same time, the particle sediment between the two transverse scrapers 30 is moved by the water flow and is also scraped into between the first filter layer 33 and the second filter layer 34 by the transverse scraper 30. A collection slot 17 is provided on the elastic membrane 16 at the bottom of the filter disc 11. The collection slot 17 is located between the first filter layer 33 and the second filter layer 34. A storage slot 18 for storing particle sediment is provided at the bottom of the filter disc 11, and its upper end is configured to be wedge-shaped for easy entry of particle sediment. The storage slot 18 is located below the collection slot 17.A number of wedge blocks 19 are fixedly installed on the inner walls on both sides. The wedge blocks 19 are arranged in a vertical cross arrangement, and the inclined surfaces are all facing upwards. The particles are scraped to the space between the first filter layer 33 and the second filter layer 34 and are affected by gravity. Finally, they fall into the storage tank 18 through the collection tank 17. The inclined surfaces of the wedge blocks 19 do not prevent them from falling, and the straight surfaces of the wedge blocks 19 prevent them from moving upwards, so that the particle sediment in the storage tank 18 is not easily affected by the water flow and flows out.

[0037] Specifically, when water flows through the propeller 8, it will drive the propeller 8 to rotate, and the propeller 8 will drive the rotating shaft 7 and the rotating ring 9 to rotate, and at the same time make the arc block 10 also perform a circular motion. When water flows through the filter disc 11, the larger particle sediments in the water flow will be intercepted by the first filter layer 33 and collected in the first filter tank 31, and the smaller particle sediments in the water flow will be intercepted by the second filter layer 34 and collected in the second filter tank 32. During the rotation of the rotating ring 9, the arc block 10 on it will be driven to push the first sliding column 12 and the second sliding column 13. Since the number of arc blocks 10 is an integer multiple of four, the rotating ring 9 will repeatedly drive the four arc blocks 10 on it to push the two first sliding columns 12 and the two second sliding columns 13 at the same time. One slide post 12 will drive the corresponding first connecting plate 14 and the corresponding first connecting block 20 to move, and make all the first sliding bars 22 move backward, so that the width of all the first filter slots 31 will increase. The two second slide posts 13 will drive the corresponding second connecting plate 15 and the corresponding second connecting block 26 to move, and make all the second sliding bars 24 move backward, so that the width of all the second filter slots 32 will increase. The first sliding bar 22 and the second sliding bar 24 are reset by the elasticity of the elastic plate 25, and the first slide post 12 and the second slide post 13 are reset, so that the arc block 10 can push it again. During the movement of the first slide bar 22, the corresponding upper scraper 28 and the lower scraper 29 will be driven to move synchronously, and the upper scraper 28 and the lower scraper 29 will be pushed by the convex strip 27. 8 and the limit of the end of the lower scraper 29, the end of the upper scraper 28 will move upward in an arc shape to scrape the particle sediment in the corresponding area of ​​the second filter tank 32 outward along the arc, and the end of the lower scraper 29 will move downward in an arc shape to scrape the particle sediment in the corresponding area of ​​the second filter tank 32 outward along the arc, and the second sliding bar 24 will also move backward at the same time, so that the width of the second filter tank 32 becomes larger, reducing the friction between the particle sediment and the two sides of the second filter tank 32 during the scraping process, and at the same time, the particle sediment in the second filter tank 32 is intercepted by the convex strip 27, so that the upper scraper 28 and the lower scraper 29 can scrape the particle sediment, and finally fall into the first filter layer 33 and the second filter layer 34. When the first sliding bar 22 is reset, it will drive the upper scraper 28 and the end of the lower scraper 29 are reset, and the upper scraper 28 and the lower scraper 29 are reset by their own elasticity. When the second sliding bar 24 moves backward, it will drive the corresponding transverse scraper 30 to move backward. When the particle sediment in the water enters the first filter tank 31, it is limited by the arc surface at the end of the transverse scraper 30, so that part of it enters between the two transverse scrapers 30, and part of it enters the arc-shaped scraping area of ​​the transverse scraper 30. During the backward scraping process of the transverse scraper 30, part of the particle sediment is scraped to between the first filter layer 33 and the second filter layer 34. At the same time, due to the backward movement of the first sliding bar 22, the width of the first filter tank 31 becomes larger, which reduces the friction between the particle sediment and the two sides of the first filter tank 31, making it easier for the transverse scraper 30 to scrape.At the same time, the granular sediment between the two transverse scrapers 30 is moved by the water flow, and is also scraped into the space between the first filter layer 33 and the second filter layer 34 by the transverse scraper 30. After being scraped to the space between the first filter layer 33 and the second filter layer 34, it is affected by gravity and finally falls into the storage tank 18 through the collection tank 17. The inclined surface of the wedge block 19 does not prevent it from falling, and the straight surface of the wedge block 19 prevents it from moving upward, so that the granular sediment in the storage tank 18 is not easily affected by the water flow and flows out. When the water flow in the inner tube 1 flows through the buffer plate 4, since the inclination direction of the buffer plate 4 is opposite to the direction of the water flow, part of the water flow is blocked, thereby slowing down the flow rate and pressure of the water and reducing the wear on the bend of the inner tube 1. When the inner tube 1 is subjected to a large pressure and deforms and expands, the pressure-resistant tube 2 provides a resistance, so that the elastic block 3 is compressed and deformed, and at the same time, an inward thrust is given to the inner tube 1 to prevent the pressure in the inner tube 1 from increasing and expanding and being damaged.
