Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and more specifically, to a water pipe. Background Technology

[0002] Spiral wound pipe is a type of pipe made of high-density polyethylene or nylon through winding and welding. It can be divided into several categories, such as large-diameter spiral wound pipe, double-wall spiral wound pipe, and hollow-wall spiral wound pipe. Due to its excellent wear resistance, aging resistance, and corrosion resistance, it is widely used in the field of wire and cable protection for various engineering machinery and hydraulic equipment. Among them, hollow-wall spiral wound pipe has the most widespread application. The production of hollow-wall spiral wound pipe adopts a heat setting process. The raw material is heated and plasticized by a plastic extruder and extruded into thin strips. After the strips are extruded from the die head, they are wound by a winding machine and cooled and shaped by a cooling device. Then, they can be conveyed and cut.

[0003] Patent CN117325442A discloses a uniform cooling device for hollow-walled wound pipes, including an installation platform and a winding equipment body and a cooling water tank respectively disposed at its upper and lower ends; multiple sets of rotary drive mechanisms are arranged side by side on one side of the installation platform; a cooling device and a water pump are installed on the cooling water tank; a water supply pipe is provided on both sides of the winding equipment body, and a nozzle is connected to one end of the water supply pipe; a fan is also installed on the cooling water tank, and an annular nozzle is provided on the outside of the nozzle, with the output end of the fan connected to the annular nozzle; this achieves uniform cooling of the inner and outer walls of the pipe, resulting in good cooling effect. However, in the above solution, only the inner and outer surfaces of the pipe are cooled, and the interior of the pipe sidewall cannot be directly cooled, resulting in the internal temperature of the pipe sidewall not decreasing in time, uneven cooling of the pipe in the diameter direction, causing product shrinkage or even pores. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot directly cool the interior of the pipe sidewall, and to provide a water inlet pipe that can achieve uniform cooling of the pipe sidewall at different positions in the diameter direction.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A water supply pipe is provided, including a pipe body, a water supply pipeline and a water rod. The outer wall of the pipe body is provided with a plurality of cooling holes extending into the inner wall of the pipe body. The water rod is inserted into the cooling holes and is connected to the water supply pipeline.

[0006] In this utility model, when cooling the pipe body, a water rod is inserted into the cooling hole on the pipe body. Water is input into the water rod through the water supply pipeline, absorbs the heat of the pipe body, and then flows into the water supply pipeline. While cooling the inner and outer surfaces of the pipe body through methods such as blowing air and spraying water mist, the water flow in the water rod can directly cool the inside of the pipe body's sidewall, achieving uniform cooling of the pipe sidewall at different positions in the diameter direction. This makes the cooling of the pipe body more rapid and uniform, reducing the risk of internal shrinkage cavities caused by untimely cooling of the inside of the pipe sidewall.

[0007] Furthermore, the water supply pipeline includes a water delivery pipe, with an inlet and an outlet at each end, and multiple water rods connected to the water delivery pipe. When cooling the pipe body, water flows into the water delivery pipe through the inlet, passes through multiple interconnected water rods, absorbs heat from the pipe body, and then flows out of the water delivery pipe through the outlet.

[0008] Furthermore, the water rod is equipped with a water divider. One end of the water divider is fixedly connected to the inner wall of the water rod away from the axis of the tube body, while the other end of the water rod has a gap with the inner wall of the water rod near the axis of the tube body to allow water flow. The water divider can guide the water flow from the end of the water rod, that is, the end of the water divider away from the water supply pipe, thereby increasing the flow velocity of the water at the end of the water rod and generating turbulence at the end of the water divider. This improves heat exchange efficiency, avoids uneven local heat exchange caused by laminar flow of the cooling water, and enhances the cooling effect of the water flow on the interior of the tube body sidewall.

[0009] Furthermore, the cooling holes are evenly distributed along the circumference of the pipe body, and the water supply pipe is wrapped around the pipe body. A water rod on the water supply pipe is inserted into the cooling holes evenly distributed around the circumference of the pipe body, allowing the water rod to cool the pipe body more evenly.

[0010] Furthermore, the water supply pipe is a flexible hose. When installing the water supply pipe, simply bend it, wrap it around the pipe body, and insert the water rod into the cooling hole to complete the installation. The operation is simple, and it can be installed on pipe bodies with different outer diameters or different cooling hole spacings, making it flexible and convenient to use.

[0011] Furthermore, the water supply pipes are provided in two or more configurations, arranged along the axis of the pipe body, and connected in series or parallel. Providing two or more water supply pipes arranged along the pipe body axis enhances the cooling effect on the pipe body, making the cooling effect more uniform in the axial direction. Series connection between water supply pipes means that the outlet of one water supply pipe is connected to the inlet of another water supply pipe; parallel connection means that the water supply equipment supplies cooling water to the inlets of different water supply pipes.

[0012] Furthermore, the multiple water rods on two adjacent water pipes are staggered along the circumference of the pipe body. This makes the distribution of water rods on the circumference of the pipe body denser, and the cooling effect on the pipe body more uniform in the circumferential direction.

[0013] Furthermore, the pipe body includes a body section and an end section, with the end section connected to both ends of the body section. The wall thickness of the end section is greater than that of the body section, and the inner wall of the end section is flush with the inner wall of the body section. The cooling holes are located on the outer wall of the end section. The body section has a thinner wall, allowing for uniform cooling using traditional methods such as blowing air or spraying water mist. A water rod is inserted into the side wall of the end section through the cooling holes, enhancing the cooling effect on the end section and making the cooling effect on the end section and body section more similar, resulting in uniform cooling of the pipe body along its axial direction. The thicker end section also improves the connection strength of the pipe body.

[0014] Furthermore, the tube body section includes an inner layer, an outer layer, and a hollow ribbed tube, with the hollow ribbed tube disposed between the inner and outer layers. The tube end section has a single-layer solid wall structure. The hollow ribbed tube between the inner and outer layers of the tube body section reduces weight while improving the heat dissipation performance of the tube body section, making it easier to achieve radially uniform cooling.

[0015] Furthermore, the cooling hole is a blind hole, and the radial position of the bottom of the cooling hole is located between the outer layer and the inner layer of the tube body section. The water rod abuts against the bottom of the cooling hole. The water rod is inserted into the cooling hole until it abuts against the bottom of the cooling hole. After the water flows past the end of the water rod, it directly cools the bottom of the cooling hole, thereby enhancing the cooling effect on the radially positioned portion of the tube end section and the hollow ribbed tube. This makes the cooling effect of the tube end section and the interior of the tube body section similar, resulting in a more uniform cooling effect of the tube body in the axial direction.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The water inlet pipe of this utility model has the following characteristics: 1. The water flow in the water rod can directly cool the inside of the pipe sidewall, achieving uniform cooling of the pipe sidewall at different positions in the diameter direction, reducing the risk of internal shrinkage caused by untimely cooling of the inside of the pipe sidewall; 2. The water divider can guide the water flow from the end of the water rod, generating turbulence at the end of the water divider, improving heat exchange efficiency, avoiding uneven local heat exchange caused by laminar flow of cooling water, and enhancing the cooling effect of the water flow on the inside of the pipe sidewall; 3. Two or more water supply pipes are set to enhance the cooling effect on the pipe body. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] Example 1 like Figures 1 to 5 The first embodiment of the water pipe of this utility model is shown, including a pipe body 1, a water supply pipe 3 and a water rod 2. The outer wall of the pipe body 1 is provided with a plurality of cooling holes 121 extending into the inner wall of the pipe body 1. The water rod 2 is inserted into the cooling holes 121 and is connected to the water supply pipe 3.

[0022] When cooling the pipe body 1, the water rod 2 is inserted into the cooling hole 121 on the pipe body 1. Water is input into the water rod 2 through the water supply pipe 3. After absorbing the heat of the pipe body 1, the water flows into the water supply pipe 3. While cooling the inner and outer surfaces of the pipe body 1 by blowing air, spraying water mist, etc., the water flow in the water rod 2 can directly cool the inside of the side wall of the pipe body 1, realizing uniform cooling of the side wall of the pipe at different positions in the diameter direction. This makes the cooling of the pipe body 1 faster and more uniform, reducing the risk of internal shrinkage of the pipe body 1 caused by the inside of the side wall of the pipe body 1 not being cooled in time.

[0023] like Figure 1 and Figure 2 As shown, the water supply pipeline 3 includes a water delivery pipe 31, with an inlet 311 and an outlet 312 at each end. Multiple water rods 2 are connected to the water delivery pipe 31. When cooling the pipe body 1, water flows into the water delivery pipe 31 through the inlet 311, passes through multiple interconnected water rods 2, absorbs heat from the pipe body 1, and then flows out of the water delivery pipe 31 through the outlet 312.

[0024] The water rod 2 is equipped with a water divider 21. One end of the water divider 21 is fixedly connected to the inner wall of the water rod 2 away from the axis of the tube body 1, and the other end of the water rod 2 has a gap with the inner wall of the water rod 2 near the axis of the tube body 1 to allow water to flow through. The water divider 21 can guide the water flow from the end of the water rod 2, that is, the end of the water divider 21 away from the water supply pipe 31, to increase the flow velocity of the water at the end of the water rod 2, generate turbulence at the end of the water divider 21, improve heat exchange efficiency, avoid the problem of uneven local heat exchange caused by laminar flow of cooling water, and enhance the cooling effect of the water flow on the interior of the side wall of the tube body 1.

[0025] Cooling holes 121 are evenly distributed along the circumference of the pipe body 1, and water pipe 31 is wrapped around the pipe body 1. Water rods 2 on the water pipe 31 are inserted into the cooling holes 121 that are evenly distributed around the circumference of the pipe body 1, so that the water rods 2 can cool the pipe body 1 more evenly.

[0026] The water supply pipe 31 is a flexible hose. When installing the water supply pipe 31, bend the water supply pipe 31 and wrap it around the pipe body 1, then insert the water rod 2 into the cooling hole 121 to complete the installation. The operation is simple and it can be installed on pipe bodies 1 with different outer diameters or different spacing of cooling holes 121, making it flexible and convenient to use.

[0027] The working principle of the water inlet pipe in this embodiment is as follows: When cooling the pipe body 1, cooling holes 121 are opened on the pipe body 1 of the semi-finished water inlet pipe, the water delivery pipe 31 is bent and wrapped around the pipe body 1 so that the water rod 2 is aligned with the multiple cooling holes 121 evenly distributed on the circumference of the pipe body 1, the water rod 2 is inserted into the cooling holes 121 on the pipe body 1, and the cooling water is successively input into the multiple water rods 2 connected to the water delivery pipe 31 through the water supply pipe 3. When the cooling water flows through the water rod 2, the water flow is blocked by the water divider 21 and flows towards the end of the water rod 2 under the guidance of the water divider 21, forming turbulence at the end of the water rod 2, which enhances the cooling effect. After the cooling water flows past the end of the water rod 2, it flows into the water delivery pipe 31 from the other side of the water divider 21. While the cooling water flows in the water rod 2, it directly absorbs the heat inside the side wall of the pipe body 1, making the cooling effect of the pipe body 1 more rapid and uniform in the direction of the diameter of the pipe body 1.

[0028] Example 2 This embodiment is the second embodiment of the water inlet pipe of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 3 and Figure 4 As shown, there are two or more water supply pipes 31, arranged along the axis of the pipe body 1, and connected in series or parallel. Arranging two or more water supply pipes 31 along the axis of the pipe body 1 enhances the cooling effect on the pipe body 1, making the cooling effect more uniform in the axial direction. Series connection of water supply pipes 31 means that the outlet 312 of one water supply pipe is connected to the inlet 311 of another water supply pipe 31; parallel connection means that the water supply equipment supplies cooling water to the inlets 311 of different water supply pipes 31. In this embodiment, two or more water supply pipes 31 are connected in parallel.

[0029] Multiple water rods 2 on two adjacent water pipes 31 are staggered along the circumference of the pipe body 1. This makes the distribution of water rods 2 on the circumference of the pipe body 1 more dense, and the cooling effect on the pipe body 1 more uniform in the circumferential direction of the pipe body 1.

[0030] In this embodiment, as Figure 3 and Figure 4As shown, two water supply pipes 31 are wound around the pipe body 1, referred to as the first water supply pipe 313 and the second water supply pipe 314 respectively. Multiple water rods 2 connected to the first water supply pipe 313 are referred to as the first water rods 22, and multiple water rods 2 connected to the second water supply pipe 314 are referred to as the second water rods 23. Cooling holes 121 that cooperate with the first water rods 22 are referred to as the first cooling holes, and cooling holes 121 that cooperate with the second water rods 23 are referred to as the second cooling holes. At least one first water rod 22 on the first water supply pipe 313 is located circumferentially between the inlet 311 and the outlet 312 of the second water supply pipe 314, and at least one second water rod 23 on the second water supply pipe 314 is located circumferentially between the inlet 311 and the outlet 312 of the first water supply pipe 313. This prevents the part of the pipe body 1 located between the inlet 311 and the outlet 312 of the water supply pipes 31 from being uncooled by water rods 2, thereby ensuring uniform cooling of the pipe body 1 in the circumferential direction.

[0031] The working principle of the water inlet pipe in this embodiment is as follows: When cooling the pipe body 1, cooling holes 121 are opened on the pipe body 1 of the semi-finished water inlet pipe. The first water delivery pipe 313 and the second water delivery pipe 314 are bent, and the two water delivery pipes 31 are wrapped around the pipe body 1 so that the water rod 2 is aligned with the multiple cooling holes 121 evenly distributed on the circumference of the pipe body 1. The first water rod 22 is inserted into the first cooling hole on the pipe body 1, and the second water rod 23 is inserted into the second cooling hole on the pipe body 1. Cooling water is introduced into the two water delivery pipes 31. The water flows into multiple first water rods 22 and second water rods 23, which are respectively connected to the first water supply pipe 313 and the second water supply pipe 314. When the cooling water flows through the water rod 2, the water flow is blocked by the water divider 21. Under the guidance of the water divider 21, the water flows towards the end of the water rod 2. After passing the end of the water rod 2, it flows into the water supply pipe 31 from the other side of the water divider 21. While the cooling water flows in the water rod 2, it directly absorbs the heat inside the side wall of the pipe body 1, making the cooling effect on the pipe body 1 more rapid and uniform in the direction of the diameter of the pipe body 1.

[0032] Example 3 This embodiment is the third embodiment of the water inlet pipe of this utility model. This embodiment is similar to embodiment two, except that, as Figure 5 As shown, the tube body 1 includes a tube body section 11 and a tube end section 12. The tube end section 12 is connected to both ends of the tube body section 11. The wall thickness of the tube end section 12 is greater than that of the tube body section 11. The inner wall of the tube end section 12 is flush with the inner wall of the tube body section 11. Cooling holes 121 are provided on the outer wall of the tube end section 12. The wall thickness of the tube body section 11 is relatively thin, and it can be uniformly cooled by traditional cooling methods such as blowing air or spraying water mist. The water rod 2 is inserted into the interior of the side wall of the tube end section 12 through the cooling holes 121 to enhance the cooling effect on the tube end section 12, making the cooling effect on the tube end section 12 and the tube body section 11 more similar, so that the tube body 1 is uniformly cooled in the axial direction.

[0033] The tube body section 11 includes an inner layer 112, an outer layer 111, and a hollow finned tube 113. The hollow finned tube 113 is disposed between the inner layer 112 and the outer layer 111. The tube end section 12 has a single-layer solid wall structure. The hollow finned tube 113 between the inner layer 112 and the outer layer 111 of the tube body section 11 reduces weight while improving the heat dissipation performance of the tube body section 11, making it easier to achieve radial uniform cooling.

[0034] In this embodiment, the pipe body 1 is an HDPE pipe, and the pipe body section 11 is made by an integral winding molding process; the pipe end section 12 and the pipe body section 11 are connected by hot melt butt welding, and the tensile strength of the interface between the pipe end section 12 and the pipe body section 11 is greater than or equal to the tensile strength of the pipe end section 12 and the pipe body section 11, and the strength of the pipe end section 12 and the pipe body section 11 is greater than or equal to 18MPa.

[0035] like Figure 6 As shown, the cooling hole 121 is a blind hole. The radial position of the bottom of the cooling hole 121 is located between the outer layer 111 and the inner layer 112 of the tube body section 11. The water rod 2 abuts against the bottom of the cooling hole 121. The water rod 2 is inserted into the blind hole until it abuts against the bottom of the blind hole. After the water flows over the end of the water rod 2, it directly cools the bottom of the blind hole, thereby enhancing the cooling effect on the part of the tube end section 12 and the hollow rib tube 113 that are in the same radial position. This makes the cooling effect of the tube end section 12 and the interior of the tube body section 11 similar, and makes the cooling effect of the tube body 1 more uniform in the axial direction.

[0036] The working principle of the water pipe in this embodiment is as follows: 1. HDPE granules are used as raw materials. The inner layer 112, outer layer 111 and hollow rib tube 113 are extruded simultaneously by an extruder. The pipe body section 11 is wound into a pipe body section 11 by a winding machine. Then, the pipe end section 12 is extruded by an extruder. The two ends of the pipe body section 11 are heat-fused to the pipe end section 12.

[0037] 2. When the tube body 1 is formed and in a semi-molten state, a cooling hole 121 is opened at the tube end section 12 using a drilling device.

[0038] 3. Wrap the water pipe 31 around the pipe end section 12, align the water rod 2 with the cooling hole 121, insert the water rod 2 into the cooling hole 121 and abut it against the bottom of the cooling hole 121.

[0039] 4. Cool the inner and outer walls of the pipe body section 11 by means of blowing air, spraying water mist, etc., and at the same time, cool water is introduced into the water supply pipe 31. The cool water flows through multiple water rods 2 through the water supply pipe 31 to cool the pipe end section 12 until the pipe end section 12 and the pipe body section 11 are cooled and formed. 5. Remove the water rod 2 and the water pipe 31, and perform further processing on the pipe body 1 to produce the finished water pipe.

[0040] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
