Description

Technical Field

[0001] The utility model relates to the technical field of agricultural irrigation pipes, in particular to a two-color PVC pipe for agricultural irrigation. Background Art

[0002] With the modernization of agriculture and the emphasis on water resources management, agricultural PVC pipes with anti-algae function are suitable for various agricultural irrigation systems and water conservancy projects, such as drip irrigation systems, sprinkler irrigation systems and drainage systems.

[0003] During the use of existing PVC pipes, since the pipes are often exposed to water sources and sunlight, algae are easily grown inside and polluted. The pollution of the inner wall of the pipe will affect the circulation of water and the water quality, and it is easy to block the water outlet. Therefore, in order to advance the technology of the industry, better ensure the use of PVC pipes in agricultural irrigation, and improve the competitiveness of core technologies, this application proposes a new implementation plan that is different from the existing PVC pipe structure used in agricultural irrigation. Utility Model Content

[0004] The utility model aims to solve the problem that the existing PVC pipes are not well used in irrigation, and proposes a two-color PVC pipe for agricultural irrigation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A two-color PVC pipe for agricultural irrigation, including a pipe body, the pipe body including an inner layer pipe, the outer surface of the inner layer pipe is provided with an outer layer pipe, and the outer surface of the outer layer pipe is provided with a wear-resistant coating, the outer surface of the pipe body is provided with a plurality of connecting components, the connecting components include a connecting ring, the outer surface of the connecting ring is integrally formed with two side seats, one side of the side seat is provided with a mounting hole, and the inner thread of the mounting hole is inserted with a connecting screw.

[0007] Furthermore, the inner tube is a black PVC tube.

[0008] Furthermore, the outer tube is a white PVC tube.

[0009] Furthermore, the wear-resistant coating is a polyurethane coating.

[0010] Furthermore, a rubber ring is fixedly clamped on the inner surface of the connecting ring, and the rubber ring is sleeved on the outer surface of the pipe body.

[0011] Furthermore, connecting ribs are integrally formed between the connecting ring and the side seat.

[0012] The beneficial effects of the utility model are:

[0013] 1. The design of combining the outer tube and the inner tube can ensure the anti-algae property of the pipe body. Since the outer tube is a white PVC tube and the inner tube is a black PVC tube, the two-color pipe body has a good light-blocking effect. In this way, the black PVC tube is not light-transmitting, and the algae cannot photosynthesize and reproduce, thereby avoiding algae pollution inside the pipe body and clogging inside the pipe body.

[0014] 2. The design of the white PVC pipe outside the black PVC pipe makes it difficult for the sunlight temperature to be transmitted to the inside of the pipe body. In this way, the black PVC pipe inside the pipe body can be prevented from absorbing heat, and the temperature of the irrigation water flowing therein can be prevented from rising, thereby ensuring the water quality and the normal use of the pipe body for irrigating crops.

[0015] 3. The design of the connecting assembly can fix the pipe body during use. If the pipe body is set on the ground, the connecting screws can be inserted into the ground. If the pipe body is set at a high place, the connecting screws are installed with the connecting seat at the high place. In this way, the pipe body is fixed by the connecting assembly, ensuring the stability of the pipe body when used in agricultural irrigation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 , a two-color PVC pipe for agricultural irrigation, including a pipe body 1, the pipe body 1 includes an inner layer pipe 101, the inner layer pipe 101 is a black PVC pipe, the outer surface of the inner layer pipe 101 is provided with an outer layer pipe 102, the outer layer pipe 102 is a white PVC pipe, and the white and black PVC raw materials are sheared, extruded, melted, and pre-plasticized by a twin-screw extruder and finally produced in a mold in a co-extruded manner to form a combination of the inner layer pipe 101 and the outer layer pipe 102. The design of combining the outer layer pipe 102 and the inner layer pipe 101 can ensure the anti-algae performance of the pipe body 1. Since the outer layer pipe 102 is a white PVC pipe and the inner layer pipe 101 is a black PVC pipe, the two-color pipe body 1 has a good light blocking effect. In this way, the black PVC pipes are not light-transmitting, so algae cannot photosynthesize and reproduce, thereby avoiding algae pollution inside the pipe body 1 and clogging inside the pipe body 1. The design of the white PVC pipe outside the black PVC pipe makes it difficult for the sunlight temperature to be transmitted to the inside of the pipe body 1. In this way, the black PVC pipe inside the pipe body 1 can be prevented from absorbing heat, and the temperature of the irrigation water flowing therein can be prevented from rising, thereby ensuring the water quality and the normal use of the pipe body 1 for irrigating crops. The outer surface of the outer layer pipe 102 is provided with a wear-resistant coating 103, and the wear-resistant coating 103 is a polyurethane coating. The polyurethane coating has good wear-resistant effect, can protect the pipe body 1, avoid scratches on the surface of the pipe body 1, and ensure the service life of the pipe body 1.

[0023] The outer surface of the pipe body 1 is provided with a plurality of connection components 2, the connection components 2 include a connection ring 201, the outer surface of the connection ring 201 is integrally formed with two side seats 202, one side of the side seat 202 is provided with a mounting hole, and the inner thread of the mounting hole is inserted with a connection screw 203. The design of the connection component 2 can fix the pipe body 1 when it is used. If the pipe body 1 is set on the ground, the connection screw 203 can be inserted into the ground. If the pipe body 1 is set at a high place, the connection screw 203 is installed with the connection seat at the high place, so that the connection component 2 is used to fix the pipe body 1 when it is used. Part 2 fixes the pipe body 1 to ensure the stability of the pipe body 1 when used in agricultural irrigation. The inner surface of the connecting ring 201 is fixedly clamped with a rubber ring 204, and the rubber ring 204 is sleeved on the outer surface of the pipe body 1. The design of the rubber ring 204 ensures that the connecting component 2 is sleeved on the outer surface of the pipe body 1 to prevent shaking. A connecting rib 205 is integrally formed between the connecting ring 201 and the side seat 202. The design of the connecting rib 205 can reinforce the connection between the connecting ring 201 and the side seat 202, thereby improving the stability of the connecting component 2 when used.

[0024] Working principle of this embodiment: When in use, the operator installs the pipe body 1 in the water delivery system of agricultural irrigation. At this time, since the outer tube 102 of the pipe body 1 is a white PVC tube, the outer tube 102 is covered by the outer tube 102 to protect the inner tube 101. The combination of the white outer tube 102 and the black inner tube 101 makes the pipe body 1 have a good light-blocking effect on sunlight, while the black inner tube 101 is not light-transmissive, so that the algae cannot photosynthesize and cannot reproduce, thereby achieving the pipe body. 1 has an anti-algae effect; at the same time, due to the design of the white outer tube 102 outside the black inner tube 101, the sunlight temperature is not easy to be transmitted to the inside of the pipe body 1, so that the black inner tube 101 in the pipe body 1 can be prevented from absorbing heat and the temperature of the irrigation water flowing therein can be prevented from rising, thereby ensuring the use of the pipe body 1 for irrigating crops; and the wear-resistant coating 103 on the outside of the outer tube 102 can improve the wear resistance of the outer surface of the pipe body 1 and avoid scratches on its surface, thereby increasing the service life of the pipe body 1.

[0025] After the pipe body 1 is installed, it can be fixed by the connecting component 2. If the pipe body 1 is set on the ground, the connecting screw 203 can be inserted into the ground. If the pipe body 1 is set at a high place, the connecting screw 203 is installed with the connecting seat at the high place. In this way, the pipe body 1 is fixed by the connecting component 2, thereby ensuring the stable use of the pipe body 1 in agricultural irrigation.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
