[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a mining wear-resistant, corrosion-resistant and anti-corrosion pipeline, including a steel pipe 1. An anti-oxidation material layer 2 is fixedly connected to the outer surface of the steel pipe 1. A corrosion-resistant rubber layer 3 is fixedly connected to the inner wall of the steel pipe 1. Flow guiding grooves 301 are formed in the inner wall of the corrosion-resistant rubber layer 3. The flow guiding grooves 301 are uniformly distributed in a spiral shape from right to left, and the cross-sectional shape of the flow guiding grooves 301 is a continuous sine curve. The liquid flow flows along the spiral-shaped flow guiding grooves 301 in the corrosion-resistant rubber layer 3, thereby enhancing the impact force of the liquid flow and impacting the particulate impurities that sink to the lower inner wall, carrying the impurities to flow and being blocked by the filtering holes 401 on the end cover 4, thereby reducing the impurities deposited on the lower inner wall of the pipeline, reducing the probability of the impurities sticking together, being more convenient for cleaning, thus ensuring the normal use of the pipeline, and further ensuring the work progress. A left side surface of the steel pipe 1 is provided with an end cover 4. Filtering holes 401 are formed in the left side surface of the end cover 4. An operating handle 5 is fixedly connected to the left side surface of the end cover 4. A plugging rod 6 is fixedly connected to the right side surface of the end cover 4. By rotating the operating handle 5, the plugging rod 6 and the plugging groove 101 are separated, and then the end cover 4 can be separated from the steel pipe 1, and then the impurities blocked by the filtering holes 401 inside the steel pipe 1 can be cleaned, further reducing the number of impurities inside the pipeline, thus ensuring the normal use of the pipeline, and further ensuring the work progress. A plugging groove 101 is formed in the left side surface of the steel pipe 1. Vibration fins 7 are fixedly connected to the right side surface of the end cover 4.
[0019] In the present utility model, in order to facilitate the operation of the operating handle 5, a rubber layer is wrapped on the outer surface of the operating handle 5. Friction anti-slip patterns are formed on the outer surface of the rubber layer. The rubber layer with the friction anti-slip patterns can further increase the friction force between the human hand and the outer surface of the operating handle 5, reducing the probability of slipping, thereby facilitating the operation of the operating handle 5.
[0020] In the present utility model, in order to ensure the connection strength between the end cover 4 and the steel pipe 1, the plugging rod 6 is set to be composed of a plugging column and a blocking piece. The diameter of the blocking piece is larger than that of the plugging column. The larger diameter of the blocking piece than that of the plugging column can reduce the probability of the plugging rod 6 and the plugging groove 101 being disengaged, thereby ensuring the connection strength between the end cover 4 and the steel pipe 1.
[0021] In the present utility model, in order to ensure the connection strength between the end cover 4 and the steel pipe 1, the number of the plugging rods 6 and the plugging grooves 101 is set to be three groups. The three groups of plugging rods 6 and the three groups of plugging grooves 101 are uniformly distributed around the centers of the end cover 4 and the steel pipe 1 respectively, and the plugging rods 6 and the plugging grooves 101 are adapted to each other. The three groups of uniformly distributed plugging rods 6 and plugging grooves 101 can ensure the connection strength between the end cover 4 and the steel pipe 1.
[0022] In the present utility model, in order to prevent the oxidation of the pipeline and ensure the corrosion resistance of the pipeline, an anti-oxidation material layer is provided on both the inner and outer surfaces of the steel pipe 1, and the corrosion-resistant rubber layer 3 is made of polyisobutylene rubber material. Through this arrangement, the oxidation of the pipeline is prevented and the corrosion resistance of the pipeline is ensured.
[0023] In the present utility model, in order to reduce the number of impurities inside the pipeline, the number of vibration fins 7 is ten groups. The ten groups of vibration fins 7 are axially symmetrically distributed on the right side surface of the end cover 4, and the directions of the ten groups of vibration fins 7 are vertically downward. The vertically downward vibration fins 7 can reduce the adhesion of impurities. The liquid flow impacts the vibration fins 7, causing the vibration fins 7 to vibrate, thereby shaking off the impurities attached to the right side surface of the end cover 4, which facilitates the cleaning of the impurities, and further reduces the number of impurities inside the pipeline.
[0024] During use, the pipeline is installed and the liquid flow is introduced. The liquid flow moves forward spirally along the diversion groove 301. The liquid flow carries the impurities, and the impurities are filtered by the filter holes of the end cover 4. The liquid flow impacts the vibration fins 7, and the vibration of the vibration fins 7 drives the end cover 4 to vibrate. The impurities on the right side surface of the end cover 4 are shaken off. After a period of time, the liquid flow is disconnected, and the operation handle 5 is rotated counterclockwise. The operation handle 5 drives the end cover 4 to rotate, and the end cover 4 drives the insertion rod 6 to rotate and separate from the insertion slot 101, so as to clean the impurities inside the pipeline. After the cleaning is completed, the insertion rod 6 is aligned with the insertion slot 101 and inserted, and the operation handle 5 is rotated clockwise. The operation handle 5 drives the end cover 4 to rotate, and the end cover 4 drives the insertion rod 6 to rotate so that the end cover 4 is connected to the steel pipe 1.
[0025] In summary, for this mining wear-resistant, corrosion-resistant, and anti-corrosion pipeline, the liquid flow flows along the spiral-shaped diversion groove 301 in the corrosion-resistant rubber layer 3, thereby enhancing the impact force of the liquid flow to impact the particulate impurities that sink to the lower inner wall, carrying the impurities to flow and being blocked by the filter holes 401 on the end cover 4, thereby reducing the impurities deposited on the lower inner wall of the pipeline, reducing the probability of the impurities sticking together, being more convenient for cleaning, ensuring the normal use of the pipeline, and further ensuring the work progress.
[0026] For this mining wear-resistant, corrosion-resistant, and anti-corrosion pipeline, by rotating the operation handle 5, the insertion rod 6 and the insertion slot 101 are separated, and further, the end cover 4 can be separated from the steel pipe 1, and then the impurities blocked by the filter holes 401 inside the steel pipe 1 can be cleaned, further reducing the number of impurities inside the pipeline, ensuring the normal use of the pipeline, and further ensuring the work progress.
