Description

Technical Field

[0001] This utility model relates to the field of impeller tube technology, and in particular to an irregularly shaped outer impeller tube. Background Technology

[0002] Existing double-wall corrugated pipes, as shown in patent application number CN202110720023.X, include a double-wall corrugated pipe body and corrugations disposed on the outer side of the double-wall corrugated pipe. The corrugations on the outer side of the double-wall corrugated pipe body increase the ring stiffness of the double-wall corrugated pipe. Although the existing double-wall corrugated pipes generally meet the ring stiffness specifications, on-site quality inspectors often need to press the double-wall corrugated pipe with their fingers to feel its ring stiffness. The cross-section of the corrugations in existing double-wall corrugated pipes is basically a single-corrugated arc-shaped structure. When quality inspectors press down on the corrugations with their fingers, the corrugations are easily deformed downwards by elasticity, forming indentations. Although the overall ring stiffness of the double-wall corrugated pipe actually meets the requirements, it is easy to give the illusion that the ring stiffness is unqualified. Utility Model Content

[0003] In order to solve the defect that the crests of existing double-walled corrugated pipes are prone to deformation after being pressed, this utility model provides an irregularly shaped outer wheel impeller pipe, which is less prone to deformation after being pressed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An irregularly shaped outer impeller tube includes a tube body and multiple outer wheels arranged sequentially along the length of the tube body. One end of the tube body is provided with a socket and the other end is provided with a spigot. The outer wheels are hollow. A first groove is provided circumferentially at the center of the top of the outer wheel. Annular ribs are formed on both sides of the first groove on the top of the outer wheel. The width of the annular ribs is w1, where w1 <= 2cm. Multiple second grooves are provided circumferentially along the annular ribs, and the second grooves penetrate into the first groove. The width of the top of the outer wheel is w2, and the depth of the first groove is d1. When w2 <= 5cm, the cross-section of the first groove is arc-shaped, and d1 / w1 < 1 / 3. When w2 > 5cm, the cross-section of the first groove is U-shaped, and d1 / w1 > 1 / 2.

[0006] With the above-mentioned design, firstly, a first groove is provided circumferentially at the center of the top of the outer wheel. On the one hand, the first groove itself is a groove, so it is not easy to sink when pressed on it. On the other hand, the design of the first groove makes the top of the outer wheel form a narrow annular rib. The width of the annular rib is smaller than the width of the crest of the traditional impeller tube, and the rigidity is greater. It is also not easy to sink when pressed on the annular rib. In summary, when quality inspectors press the outer wheel with their fingers, the outer wheel will basically not sink, giving them more confidence in the product. Secondly, the second groove further increases the surface area of ​​the impeller tube. When the impeller tube is used underground, the contact area with the soil is larger, which can better prevent soil erosion.

[0007] Furthermore, the width of the second groove is w3, and the distance between two adjacent second grooves is w4; when w2 <= 5cm, w4<w3;w2> At 5cm, w4 > w3.

[0008] Furthermore, the depth of the second groove is less than or equal to d1.

[0009] Furthermore, when w2 <= 5cm, the depth of the second groove = d1; when w2 > 5cm, the depth of the second groove... <d1。

[0010] Furthermore, the second grooves on opposite sides of the first groove are aligned with each other or staggered.

[0011] Furthermore, the sidewall of the outer wheel is inclined towards the first groove, and the angle between the sidewall of the outer wheel and the tube body is α, 95°. <a<100°。 Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] like Figures 1 to 13 As shown, an irregularly shaped outer wheel impeller tube includes a tube body 2 and multiple outer wheels 3 arranged sequentially along the length of the tube body 2. One end of the tube body 2 is provided with a socket 4, and the other end is provided with a spigot 5. The outer wheels 3 are hollow structures. A first groove 6 is provided circumferentially at the center of the top of the outer wheel 3. Annular ribs 7 are formed on both sides of the top of the outer wheel 3 on the first groove 6. The width of the annular ribs 7 is w1, where w1 <= 2cm. Multiple second grooves 8 are provided circumferentially along the annular ribs 7, and the second grooves 8 penetrate into the first groove 6. The width of the top of the outer wheel 3 is w2, and the depth of the first groove 6 is d1. When w2 <= 5cm, the cross-section of the first groove 6 is arc-shaped, and d1 / w1 < 1 / 3.

[0027] When w2>5cm, the cross-section of the first groove 6 is U-shaped, and d1 / w1>1 / 2.

[0028] Through the above-mentioned design, firstly, a first groove 6 is provided circumferentially at the top center of the outer wheel 3. On the one hand, the first groove 6 is itself a groove, so it is not easy to sink when pressed on it. On the other hand, the design of the first groove 6 makes the top of the outer wheel 3 form a narrow annular rib 7. The width of the annular rib 7 is smaller than the width of the crest of the traditional impeller tube, and the rigidity is greater. It is also not easy to sink when pressed on the annular rib 7. In summary, when quality inspectors press the outer wheel 3 with their fingers, the outer wheel 3 will basically not sink, giving them more confidence in the product. Secondly, the second groove 8 further increases the surface area of ​​the impeller tube. When the impeller tube is used underground, the contact area with the soil is larger, which can better prevent soil erosion.

[0029] In this application, multiple outer wheels 3 are evenly arranged along the length of the tube body 2; the side of the outer wheel 3 away from the tube body 2 is the top of the outer wheel 3; a first groove 6 extends along the center line of the top of the outer wheel 3, so that each outer wheel 3 forms two annular ribs 7 at the top, one annular rib 7 is located on the side of the first groove 6 near the socket 4, and the other annular rib 7 is located on the side of the first groove 6 near the insertion port 5; the shape of the first groove 6 is designed according to the width w2 of the top of the outer wheel 3; in one embodiment, such as Figures 1 to 6 As shown, when w2 <= 5cm, the top width w2 of the outer wheel 3 is relatively small, the cross-section of the first groove 6 is arc-shaped, and the width of the first groove 6 is the distance w6 between the two ends of the arc. At this time, the width w1 of the annular rib 7 is (w2-w6) / 2, specifically w1 = 1.5cm, and d1 / w1 is specifically taken as 1 / 4. The depth of the first groove 6 is relatively small, which is convenient for processing; in another embodiment, as Figures 7 to 11 As shown, when w2 > 5cm, the top width w2 of the outer wheel 3 is larger, and the density of the outer wheel 3 along the length of the tube 2 is smaller. That is, there are fewer outer wheels 3 per unit length of tube 2, and the ring stiffness of the impeller tube is smaller. The cross-section of the first groove 6 is set as U-shaped, the groove width of the first groove is w6, the width of the annular rib 7 is w1 = (w2-w6) / 2, specifically w1 = 1.5cm, and d1 / w1 is specifically taken as 2 / 3. The depth d1 of the first groove 6 is relatively large. On the one hand, because the top width of the outer wheel 3 is large at this time, it is relatively easy to process the first groove 6 with a larger depth. On the other hand, the greater depth The first groove 6 increases the radial support performance of the outer wheel 3. That is, the deeper first groove 6 can reinforce the ring stiffness of the impeller tube. The first groove 6 in this application is itself a groove, so when the quality inspector's finger presses on the first groove 6, the first groove 6 is not easy to sink again. The width w1 of the annular rib 7 in this application is specifically taken as 1.5cm, which limits the width of the annular rib 7 and ensures the stiffness of the annular rib 7. When the quality inspector's finger presses on the annular rib 7, the annular rib 7 will not sink. Overall, no matter where the quality inspector presses on the top of the outer wheel 3, the top of the outer wheel 3 will not sink, making the product more reliable in terms of appearance.

[0030] The socket 4 and spigot 5 of this application refer to existing impeller pipes and will not be described in detail. The impeller pipe of this application is buried underground for use. When in use, the spigot 5 of one impeller pipe is inserted into the socket 4 of the adjacent impeller pipe. The impeller pipe of this application has a second groove 8 on the annular rib 7. The second groove 8 further increases the surface area of ​​the impeller pipe. Some small stones underground can be easily embedded in the second groove 8, making the contact area between the impeller pipe and the soil larger. Compared with traditional impeller pipes, it can better prevent soil erosion.

[0031] As an implementation, the width of the second groove 8 is w3, and the distance between two adjacent second grooves 8 is w4; when w2 <= 5 cm, w4 < w3;

[0032] when w2 > 5 cm, w4 > w3.

[0033] As shown in Figures 4 to 6 When the width w2 of the top of the outer wheel 3 <= 5 cm, the depth of the first groove 6 is small, and the contribution of the first groove 6 to the increase in the surface area of the wave wheel tube is not large enough. The distance w4 between two adjacent second grooves 8 < w3. At this time, the arrangement density of the second grooves 8 is greater and the number is more, which can further greatly increase the outer surface area of the wave wheel tube, so that the wave wheel tube has a good ability to prevent soil erosion; as shown in Figures 9 to 11 When the width w2 of the top of the outer wheel 3 > 5 cm, the depth of the first groove 6 is large, and the contribution of the first groove 6 to the increase in the surface area of the wave wheel tube is relatively large. The distance w4 between two adjacent second grooves 8 > w3. At this time, the arrangement density of the second grooves 8 is small, and the number does not need to be many, reducing the processing difficulty and improving the processing efficiency.

[0034] As an implementation, the depth of the second groove 8 <= d1.

[0035] As an implementation, when w2 <= 5 cm, the depth of the second groove 8 = d1; when w2 > 5 cm, the depth of the second groove 8 < d1.

[0036] As an implementation, the second grooves 8 on the opposite sides of the first groove 6 are aligned with each other or offset from each other.

[0037] As shown in Figures 1 to 11 For the wave wheel tube of the present application, the second grooves 8 on the left and right sides of each outer wheel 3 are symmetrically arranged; in another embodiment, as shown in Figure 12 For the wave wheel tube, the second grooves 8 of two adjacent outer wheels 3 are offset; in another embodiment, as shown in Figure 13 For the wave wheel tube, the second grooves 8 on the left and right sides of each outer wheel 3 are offset.

[0038] As an implementation, the side wall of the outer wheel 3 inclines towards the first groove 6, and the included angle between the side wall of the outer wheel 3 and the tube body 2 is a, 95° < a < 100°.

[0039] As shown in Figure 6 For the outer wheel 3 of the present application, the side close to the tube body 2 is the bottom of the outer wheel 3, the width of the bottom of the outer wheel 3 is w5, the cross-section of the outer wheel 3 is substantially an isosceles trapezoid, and the distance from the top of the outer wheel 3 to the tube body 2 is h. According to the included angle a between the side wall and the tube body 2 and geometric knowledge, the width w2 of the top of the outer wheel 3 is calculated.

[0040] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
