Description

Technical Field

[0001] This invention relates to the field of water pipe technology, and more specifically, to an anti-wear composite elastic water pipe. Background Technology

[0002] Water pipes are an indispensable and important component in daily life and industrial production, and are widely used in many scenarios such as household water supply, agricultural irrigation, building construction, and industrial fluid transportation.

[0003] However, traditional water pipes often experience wear and tear, and breakage during use due to friction and compression, especially in complex environments such as outdoor operations, industrial workshops, and agricultural irrigation, where wear is more severe and their lifespan is significantly shortened. Furthermore, traditional water pipes have poor elasticity and are prone to permanent deformation after bending or stretching, thus affecting their performance. Therefore, there is an urgent need for a wear-resistant composite elastic water pipe to solve these problems. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes an anti-wear composite elastic water pipe to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] The technical solution of this invention is implemented as follows:

[0006] A wear-resistant composite elastic water pipe includes an inner sleeve, the outer circumferential wall of which is provided with a wear-resistant sheath, and the outer circumferential wall of the wear-resistant sheath is provided with a wear-resistant component to improve the wear resistance of the water pipe.

[0007] Both ends of the wear-resistant sheath are provided with threaded grooves to facilitate the connection and installation of water pipes.

[0008] The outer circumferential wall of the inner sleeve and the inner circumferential wall of the wear-resistant sheath surround a support cavity, and an elastic component for improving the elasticity of the water pipe is provided inside the support cavity.

[0009] The elastic component includes a second spring and an elastic strip wound around the outer circumference of the inner sleeve, wherein the second spring and the elastic strip are wound alternately around the outer circumference of the inner sleeve.

[0010] The interior of the support cavity is equipped with a support component to improve the pressure resistance of the water pipe.

[0011] Preferably, the second spring and the elastic strip are both spirally wound around the outer circumference of the inner sleeve, and the winding density of the second spring and the elastic strip at the end of the inner sleeve is greater than the winding density in the middle region of the inner sleeve.

[0012] Preferably, the elastic strip includes an upper ring portion, an arc portion, a stress node portion, and a lower ring portion. The cross-section of the elastic strip is in the shape of a Chinese character 'Wang'. The stress node portion is located in the middle of the upper ring portion and the lower ring portion. The cross-sections of the upper ring portion and the lower ring portion are arc-shaped. The arc portion is provided between the upper ring portion and the stress node portion or between the lower ring portion and the stress node portion. The arc portion is concave. Through holes are arranged in the elastic strip at equal distances.

[0013] Preferably, the support assembly includes a support ring plate arranged inside the support cavity. The number of the support ring plates is four. The four support ring plates are stacked on top of each other to form a circular ring. The circumferential inner wall of the support ring plate is closely attached to the circumferential outer wall of the inner sleeve. The circumferential outer wall of the support ring plate contacts the circumferential inner wall of the wear-resistant sheath.

[0014] Preferably, extension ring plates and assembly grooves are respectively arranged at both ends of the support ring plate. The extension ring plate of one support ring plate overlaps with the assembly groove of another support ring plate. A matching component for ensuring the stable overlap of the two support ring plates is arranged on one side of the extension ring plate and the assembly groove.

[0015] Preferably, the matching component includes a matching groove opened on one side of the extension ring plate. The cross-section of the matching groove is in the shape of a wave. The matching groove includes wave crests and wave troughs. The matching grooves on the extension ring plate and the assembly groove are engaged with each other. The specification of the wave crest is smaller than that of the wave trough.

[0016] Preferably, circular ring ribs are fixedly connected to the circumferential outer wall of the support ring plate and are distributed in an annular shape at equal distances. Radial spokes are arranged on the circumferential outer wall of the circular ring ribs. The spokes are pressed against the circumferential inner wall of the wear-resistant sheath.

[0017] Preferably, mounting holes are respectively opened on one side of the extension ring plate and the assembly groove. A first spring is fixedly connected inside the mounting hole. One support ring plate is fixedly connected to another support ring plate through the first spring.

[0018] Preferably, the wear-resistant component includes rubber strips and wear-resistant balls which are arranged on the circumferential outer wall of the wear-resistant sheath in an equally spaced circular distribution. Two rubber strips are in the shape of a Chinese character 'Ren'. The wear-resistant balls are fixedly connected to the ends of the two rubber strips. <G

[0019] Preferably, the rubber strip includes a front end portion, a middle portion, and a rear end portion. The middle portion is arranged between the front end portion and the rear end portion. The front end portion is fixedly connected to the wear-resistant ball. The rear end portion is fixedly connected to the circumferential outer wall of the wear-resistant sheath. The diameters of the front end portion and the rear end portion are larger than that of the middle portion.

[0020] The beneficial effects of the present invention:

[0021] An anti-wear composite elastic water pipe provided by the present invention, through the provided elastic component, which is composed of a second spring and an elastic strip wound in a spiral and staggered manner, enables the water pipe to have both the elasticity of the second spring and the flexibility of the elastic strip. Moreover, the spiral winding is highly adapted to the cylindrical structure of the water pipe, and can evenly wrap the circumferential outer wall of the inner sleeve to make the force more balanced. When the water pipe is in use, it is connected to the water delivery pipeline through the threaded grooves at both ends of the wear-resistant sheath. Since the water pressure in the pipeline has the characteristic of attenuating from both ends to the middle section, the water pressure received at both ends of the inner sleeve is greater than that in the middle area. At this time, inside the wear-resistant sheath, the winding density of the second spring and the elastic strip at the ends of the inner sleeve is greater than that in the middle area of the inner sleeve, so that the second spring and the elastic strip form a winding state with a dense middle and sparse ends on the outer wall of the inner sleeve. At this time, the relatively dense winding at the end of the water pipe can provide stronger elastic support, reduce the deformation at the connection, and effectively extend the service life of the entire water pipe. At the same time, the distance between the middle parts of the water pipe is slightly sparse, which can make the whole water pipe lighter, more flexible and easier to bend while ensuring a certain elastic force;

[0022] And when the water pipe is subjected to vibration or pressure during the laying process or use, the second spring plays a role of primary buffer protection. Subsequently, when the pressure is transmitted into the elastic strip, since the cross-section of the elastic strip is in a king shape, a stable upper and lower support and an intermediate strengthening structure are formed through the upper ring part, the lower ring part and the intermediate stress section part inside it, thereby enhancing the structural strength of the entire elastic strip and effectively resisting the impact force during deformation;

[0023] Since the cross-sections of the upper ring part and the lower ring part are in an arc shape, it can better adapt to the bending action of the water pipe, reduce the local stress concentration during bending, make the elastic strip smoother when bending with the water pipe, and reduce the risk of fracture. The arc part is concave, which can provide a buffer space for the elastic deformation of the elastic strip. When being stretched or compressed by force, the elastic recovery ability can be enhanced through the stretching and contraction of the concave structure, and the flexibility of the elastic strip can be improved. The stress section part in the middle further strengthens the anti-deformation ability of the elastic strip, avoids the situation of the elastic strip breaking in the middle during repeated deformation, and extends the service life. The equidistant through holes provided inside the elastic strip can provide more compression and stretching space when being deformed by force, make the elasticity of the elastic strip better, and at the same time can reduce the weight of the elastic strip, making the whole water pipe lighter.

[0024] This invention provides a wear-resistant composite elastic water pipe. Through its designed support components, it significantly improves the water pipe's pressure resistance. Furthermore, when the middle section of the water pipe is subjected to external pressure or bending, the support components effectively disperse concentrated stress, preventing excessive local deformation. The pipe consists of four overlapping ring-shaped support plates. The inner circumference of each support ring plate is tightly fitted to the inner sleeve, and the outer wall contacts the wear-resistant sheath, forming a stable support structure that evenly distributes external pressure, reducing the risk of pipe deformation under pressure. The extended ring plates at both ends of the support ring plates interlock with the assembly groove via a corrugated groove. The crest of the corrugation is smaller than the trough, ensuring the stability of the overlap while allowing for a certain degree of relative movement. This allows the support components to adaptively adjust to the deformation of the water pipe, avoiding rigid support that restricts the pipe's elastic movement. The corrugated groove also increases the contact area between the support ring plates, improving stress transmission efficiency. The extended ring plates and the assembly groove are connected by a first spring; the spring's elasticity buffers external impact, further enhancing pressure resistance while improving the flexibility of the support components.

[0025] When the support ring plate of the support assembly is subjected to external pressure or internal water pressure tension, the stress is not limited to the vicinity of the stress point, but is transmitted along the radially distributed spokes on the ring ribs, spreading from the local stress point to the entire ring structure of the support ring plate. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain local area, which could lead to deformation, cracking, and other problems in the support ring plate. This enhances the structural stability and damage resistance of the support assembly, thereby improving the pressure resistance and service life of the entire water pipe.

[0026] This invention provides an anti-wear composite elastic water pipe. Through the setting of wear-resistant components, when workers pull the water pipe to lay or move it, the wear-resistant balls set on the outside of the wear-resistant sheath act as the first line of defense, which first contact the ground directly to bear friction, reducing the direct wear between the wear-resistant sheath and the ground and effectively extending the service life of the water pipe body. At the same time, the two rubber strips fixedly connected to the wear-resistant balls are in a herringbone shape. During the movement of the water pipe, debris on the ground can slide over along the tilt angle of the herringbone shape, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant balls, avoiding jamming caused by local stress concentration.

[0027] The diameter of the front and rear ends of the rubber strip is larger than that of the middle part, which enhances the connection strength with the wear-resistant ball and the wear-resistant sheath and prevents the wear-resistant ball from falling off due to the easy breakage of the rubber strip. The middle part of the rubber strip is thinner, which gives the rubber strip a certain degree of elasticity. When the wear-resistant ball is impacted, the middle part can deform slightly to buffer the impact, reduce the vibration and impact on the wear-resistant sheath, and avoid secondary damage.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0043] Please see Figures 1-11 A wear-resistant composite elastic water pipe includes an inner sleeve 2, a wear-resistant sheath 1 is provided on the outer circumference of the inner sleeve 2, and a wear-resistant component 4 is provided on the outer circumference of the wear-resistant sheath 1 to improve the wear resistance of the water pipe.

[0044] Both ends of the wear-resistant sheath 1 are provided with threaded grooves 3 to facilitate the connection and installation of water pipes;

[0045] The outer circumferential wall of the inner sleeve 2 and the inner circumferential wall of the wear-resistant sheath 1 surround a support cavity 8, and the support cavity 8 is provided with an elastic component to improve the elasticity of the water pipe.

[0046] The elastic component includes a second spring 6 and an elastic strip 7 wound around the outer circumference of the inner sleeve 2. The second spring 6 and the elastic strip 7 are wound alternately around the outer circumference of the inner sleeve 2. The water pipe can combine the elasticity of the second spring 6 and the flexibility of the elastic strip 7 by the spiral winding of the second spring 6 and the elastic strip 7. Moreover, the spiral winding is highly compatible with the cylindrical structure of the water pipe and can evenly wrap around the outer circumference of the inner sleeve 2 to make the force more balanced.

[0047] The interior of the support cavity 8 is equipped with a support component 5 to improve the pressure resistance of the water pipe.

[0048] Furthermore, the second spring 6 and the elastic strip 7 are both spirally wound around the outer circumference of the inner sleeve 2. The winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle region of the inner sleeve 2. Since the pressure of the water flow in the pipe has the characteristic of decreasing from both ends to the middle section, the water pressure at both ends of the inner sleeve 2 is greater than that in the middle region. At this time, the winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle region of the inner sleeve 2. This results in the second spring 6 and the elastic strip 7 forming a winding state with denser ends and sparser middle on the outer wall of the inner sleeve 2. The denser winding at the ends of the water pipe can provide stronger elastic support, reduce deformation at the connection, and effectively extend the service life of the entire water pipe. At the same time, the slightly sparser spacing in the middle part of the water pipe can make the water pipe lighter and more flexible, and easier to bend, while ensuring a certain elasticity.

[0049] Furthermore, the elastic strip 7 includes an upper ring portion 701, an arc-shaped portion 702, a stress joint portion 703, and a lower ring portion 704. The cross-section of the elastic strip 7 is king-shaped. The stress joint portion 703 is located between the upper ring portion 701 and the lower ring portion 704. The cross-sections of the upper ring portion 701 and the lower ring portion 704 are arc-shaped. The arc-shaped portion 702 is disposed between the upper ring portion 701 and the stress joint portion 703 or between the lower ring portion 704 and the stress joint portion 703. The arc-shaped portion 702 is concave. The elastic strip 7 has through holes 705 evenly distributed inside. Because the cross-sections of the upper ring portion 701 and the lower ring portion 704 are arc-shaped, it can better adapt to the bending action of the water pipe, reduce local stress concentration during bending, and enhance elasticity. Strip 7 is smoother when bending with the water pipe, reducing the risk of breakage. The concave arc portion 702 provides a buffer space for elastic deformation of the elastic strip 7. Under tension or compression, the expansion and contraction of the concave structure enhances the elastic recovery ability and improves the flexibility of the elastic strip 7. The stress joint portion 703 located in the middle of the elastic strip 7 further strengthens the deformation resistance of the elastic strip 7, preventing breakage in the middle of the elastic strip 7 during repeated deformation and extending its service life. The equidistant through holes 705 inside the elastic strip 7 provide more compression and expansion space under stress, making the elastic strip 7 more elastic and reducing its weight, making the entire water pipe lighter.

[0050] Furthermore, the support assembly 5 includes four support ring plates 501 disposed inside the support cavity 8. These four support ring plates 501 are stacked together to form a ring. The inner circumferential wall of the support ring plate 501 is tightly attached to the outer circumferential wall of the inner sleeve 2, and the outer circumferential wall of the support ring plate 501 is in contact with the inner circumferential wall of the wear-resistant sheath 1. Extending ring plates 50103 and assembly grooves 50104 are respectively provided at both ends of the support ring plate 501. The extension ring plate 50103 of the support ring plate 501 overlaps with the assembly groove 50104 of another support ring plate 501. Both the extension ring plate 50103 and the assembly groove 50104 are provided with mating components on one side to ensure the stable overlap of the two support ring plates 501. The inner circumferential wall of the support ring plate 501 is in close contact with the inner sleeve 2 and the outer wall is in contact with the wear-resistant sheath 1, forming a stable support structure that can evenly distribute external pressure and reduce the risk of water pipe deformation due to pressure.

[0051] Furthermore, the mating assembly includes a mating groove formed on one side of the extension ring plate 50103. The mating groove has a wavy cross-section and includes a crest 50101 and a trough 50102. The mating grooves on the extension ring plate 50103 and the assembly groove 50104 interlock with each other. The size of the crest 50101 is smaller than that of the trough 50102. This ensures the stability of the stacking while allowing a certain degree of relative movement, enabling the support assembly 5 to adaptively adjust with the deformation of the water pipe. This avoids the rigid support restricting the elastic movement of the water pipe. In addition, the wavy mating groove increases the contact area between the support ring plates 501, improving the efficiency of stress transmission.

[0052] Furthermore, the outer circumferential wall of the support ring plate 501 is fixedly connected with equidistant, ring-shaped ribs 502. The outer circumferential wall of the ring ribs 502 is provided with radially distributed spokes 503. The spokes 503 abut against the inner circumferential wall of the wear-resistant sleeve 1. When the support ring plate 501 of the support assembly 5 is subjected to external pressure or internal water pressure tension, the stress is not limited to the vicinity of the stress point, but will be transmitted along the radially distributed spokes 503 on the ring ribs 502, spreading from the local stress point to the entire ring structure of the support ring plate 501. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain local area, which could lead to deformation, cracking, and other problems in the support ring plate 501. This enhances the structural stability and damage resistance of the support assembly 5, thereby improving the pressure resistance and service life of the entire water pipe.

[0053] Furthermore, mounting holes 505 are provided on one side of both the extension ring plate 50103 and the assembly groove 50104. A first spring 504 is fixedly connected inside the mounting hole 505. One support ring plate 501 is fixedly connected to another support ring plate 501 through the first spring 504. The elasticity of the first spring 504 can buffer external impact force, further enhance the compressive strength, and improve the flexibility of the support component 5.

[0054] Furthermore, the wear-resistant component 4 includes rubber strips 402 and wear-resistant balls 401 that are equidistantly distributed in a circular pattern on the outer circumference of the wear-resistant sleeve 1. The two rubber strips 402 are in a herringbone shape, and the wear-resistant balls 401 are fixedly connected to the ends of the two rubber strips 402. The wear-resistant balls 401, located outside the wear-resistant sleeve 1, act as the first line of defense and preferentially contact the ground to directly bear friction, reducing direct wear between the wear-resistant sleeve 1 and the ground and effectively extending the service life of the water pipe body. At the same time, the two rubber strips 402 fixedly connected to the wear-resistant balls 401 are in a herringbone shape. During the movement of the water pipe, debris on the ground can slide along the tilt angle of the herringbone shape, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant balls 401, avoiding jamming caused by local stress concentration.

[0055] Furthermore, the rubber strip 402 includes a front end 40201, a middle part 40202, and a rear end 40203. The middle part 40202 is disposed between the front end 40201 and the rear end 40203. The front end 40201 is fixedly connected to the wear-resistant ball 401, and the rear end 40203 is fixedly connected to the outer circumferential wall of the wear-resistant sleeve 1. The diameters of the front end 40201 and the rear end 40203 are larger than the diameter of the middle part 40202, thereby enhancing the connection strength with the wear-resistant ball 401 and the wear-resistant sleeve 1 and preventing the wear-resistant ball 401 from falling off due to the easy breakage of the rubber strip 402. The middle part 40202 of the rubber strip 402 is thinner, thereby giving the rubber strip 402 a certain degree of elasticity. When the wear-resistant ball 401 encounters an impact, the middle part 40202 can slightly deform to buffer, reduce the vibration impact on the wear-resistant sleeve 1, and avoid secondary damage.

[0056] In summary, by means of the above technical solution of the present invention, the elastic components in the entire water pipe are composed of the second spring 6 and the elastic strip 7 wound in a spiral and staggered manner, enabling the water pipe to have both the elasticity of the second spring 6 and the flexibility of the elastic strip 7. Moreover, the spiral winding is highly adaptable to the cylindrical structure of the water pipe, and can evenly wrap the outer circumferential wall of the inner sleeve 2 to make the force more balanced. When the water pipe is in use, it is connected to the water conveyance pipeline through the threaded grooves 3 at both ends of the wear-resistant sheath 1. Since the water pressure in the pipeline has the characteristic of attenuating from both ends to the middle section, the water pressure received at both ends of the inner sleeve 2 is greater than that in the middle area. At this time, inside the wear-resistant sheath 1, the winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle area of the inner sleeve 2, so that the second spring 6 and the elastic strip 7 form a winding state with a dense end and a sparse middle on the outer wall of the inner sleeve 2. At this time, the relatively dense winding at the end of the water pipe can provide stronger elastic support, reduce the deformation at the connection, and effectively extend the service life of the entire water pipe. At the same time, the spacing in the middle part of the water pipe is slightly sparse, which can make the whole water pipe lighter, more flexible and easier to bend while ensuring a certain elastic force;

[0057] Moreover, when the water pipe is subjected to vibration or pressure during the laying process or use, the second spring 6 plays a role of primary buffer protection. Subsequently, when the pressure is transmitted into the elastic strip 7, since the cross-section of the elastic strip 7 is in a king shape, a stable upper and lower support and a middle strengthening structure are formed through the upper ring part 701, the lower ring part 704 and the middle stress section part 703 inside it, thereby enhancing the structural strength of the entire elastic strip 7 and effectively resisting the impact force during deformation;

[0058] Since the cross-sections of the upper ring part 701 and the lower ring part 704 are in an arc shape, it can better adapt to the bending action of the water pipe, reduce the local stress concentration during bending, make the elastic strip 7 smoother when bending along with the water pipe, and reduce the risk of fracture. The arc part 702 is concave, which can provide a buffer space for the elastic deformation of the elastic strip 7. When being stretched or compressed by force, the elastic recovery ability can be enhanced through the expansion and contraction of the concave structure, improving the flexibility of the elastic strip 7. The stress section part 703 located in the middle part 40202 further strengthens the anti-deformation ability of the elastic strip 7, avoiding the fracture of the middle part 40202 during repeated deformation and extending the service life. The equidistant through holes 705 arranged inside the elastic strip 7 can provide more compression and expansion space during deformation under force, making the elastic strip 7 more elastic, and at the same time can also reduce the weight of the elastic strip 7, making the whole water pipe lighter;

[0059] The support components 5, located inside the support cavity 8, can be spaced evenly according to the length of the water pipe. These components significantly improve the water pipe's pressure resistance and effectively disperse concentrated stress when the middle section of the pipe is subjected to external pressure or bending, preventing excessive local deformation. The support components 5 consist of four overlapping ring plates 501. The inner circumference of each ring plate 501 is flush with the inner sleeve 2, and the outer wall is in contact with the wear-resistant sheath 1, forming a stable support structure that evenly distributes external pressure, reducing the risk of water pipe deformation under pressure. The extended ring plates 50103 at both ends of the support ring plates 501 connect with the assembly groove 501. 04 The corrugated assembly grooves 50104 interlock with each other, with the crest 50101 being smaller than the trough 50102. This ensures the stability of the stacking while allowing a certain degree of relative movement, enabling the support component 5 to adapt to the deformation of the water pipe. This avoids the rigid support restricting the elastic movement of the water pipe. Furthermore, the corrugated assembly grooves 50104 increase the contact area between the support ring plates 501, improving the efficiency of stress transmission. The extension ring plate 50103 and the assembly grooves 50104 are connected by the first spring 504. The elasticity of the spring can buffer external impact forces, further enhancing the compressive strength while improving the flexibility of the support component 5.

[0060] When the support ring plate 501 of the support component 5 is subjected to external pressure or internal water pressure tension, the stress is not limited to the vicinity of the stress point, but will be transmitted along the radially distributed spokes 503 on the circular rib 502, spreading from the local stress point to the entire annular structure of the support ring plate 501. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain local area, which could lead to deformation, cracking and other problems in the support ring plate 501. This enhances the structural stability and damage resistance of the support component 5, thereby improving the pressure resistance and service life of the entire water pipe.

[0061] When workers pull the water pipe to lay or move it, the wear-resistant ball 401 set outside the wear-resistant sleeve 1 acts as the first line of defense and directly contacts the ground to bear friction, reducing the direct wear between the wear-resistant sleeve 1 and the ground and effectively extending the service life of the water pipe body. At the same time, the two rubber strips 402 fixedly connected to the wear-resistant ball 401 are in a herringbone shape. During the process of moving the water pipe, debris on the ground can slide over along the tilt angle of the herringbone shape, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant ball 401 and avoids jamming caused by local stress concentration.

[0062] The diameters of the front end 40201 and the rear end 40203 of the rubber strip 402 are both larger than those of the middle part 40202, thereby enhancing the connection strength with the wear-resistant ball 401 and the wear-resistant sleeve 1 and preventing the wear-resistant ball 401 from falling off due to the easy breakage of the rubber strip 402. The middle part 40202 of the rubber strip 402 is thinner, which can give the rubber strip 402 a certain degree of elasticity. When the wear-resistant ball 401 encounters an impact, the middle part 40202 can deform slightly to buffer the impact, reduce the vibration and impact on the wear-resistant sleeve 1, and avoid secondary damage.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
