[0002] The filling device for transport pipelines is a special device designed to fill liquids, gases or other media in transport pipelines. This device is usually installed at a specific location in the transport pipeline. By accurately controlling the filling amount, speed and time, it can effectively supplement or treat the transport medium. The application scenarios of the filling device for transport pipelines are very wide. In the field of environmental protection, the filling device can also be used to add treatment agents to wastewater or exhaust gas in the pipeline.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1-Figure 5 , a filling device for a transportation pipeline, comprising:

[0038] A filling container 1; an outer tube 2, one end of which is installed at the bottom of the filling container 1 and is connected to the filling container 1; an inner tube 3, which is installed in the outer tube 2 and is configured to move only toward one end of the filling container 1 in the outer tube 2; a switch part 4, which is installed in the inner tube 3 and is configured to rotate in the inner tube 3 when the inner tube 3 moves, for controlling the inner tube 3 to open and close.

[0039] Through the combination of the outer tube 2 and the inner tube 3, fast and efficient filling operations can be achieved, and the filling device can also flexibly switch to different transport pipelines for filling. The design of the inner tube 3 allows it to move to one end close to the filling container 1 when needed, which ensures the smoothness and stability of the filling process. The switch part 4 is arranged in the inner tube 3, and it can rotate when the inner tube 3 moves, so as to control the opening and closing of the inner tube 3, making the filling operation more flexible, and the filling speed and amount can be adjusted at any time according to actual needs, avoiding the problem of waste and over-filling. The design of the inner tube 3 in the outer tube 2 can effectively prevent leakage and splashing during the filling process, thereby improving the safety of the operation. The setting of the switch part 4 makes the filling process more controllable and reduces the risks caused by improper operation.

[0040] Reference Figure 2 and Figure 5 The pressurizing part 13 is installed in the filling container 1 and is configured to pressurize the filling container 1 when the inner tube 3 moves; two first sealing members 11 are installed on the outer ring of the inner tube 3 and contact the inner wall of the outer tube 2 to seal between the inner tube 3 and the outer tube 2; the second sealing member 12 is installed on the inner ring of the outer tube 2 to provide a sealed connection for the outer tube 2.

[0041] When the inner tube 3 moves, the pressurizing part 13 will pressurize the inside of the filling container 1, which can significantly improve the filling efficiency and ensure that the filling task is completed in a shorter time. Through the precise control of the pressurizing part 13, the pressure stability during the filling process can be ensured. The device adopts two first seals 11, which are installed on the outer ring of the inner tube 3 and in close contact with the inner wall of the outer tube 2, effectively preventing liquid leakage between the inner tube 3 and the outer tube 2, and ensuring the reliability of the filling process. The setting of the second seal 12 further enhances the sealing of the connection of the outer tube 2, and effectively prevents the influence of external factors on the filling process.

[0042] Reference Figure 5 The inner tube 3 includes: a moving block 9, which is installed on the outer ring of the inner tube 3. A moving groove 8 is opened on the inner wall of the outer tube 2, and the moving block 9 is connected to the moving groove 8; an elastic member 10, one end of which is installed on the moving block 9, and the other end is installed on the inner wall of the moving groove 8, which is used to provide a force for the moving block 9, and the direction of the force points to the original position of the moving block 9. The elastic member 10 adopts a stainless steel spring, and can also adopt an elastic rope; a connecting shaft 5, one end of which is connected to the outer ring of the switch part 4, and the other end passes through the inner tube 3 and extends to the moving groove 8, and is connected to a gear 6. The bottom wall of the moving groove 8 is connected to a rack 7, and the rack 7 is meshed with the gear 6.

[0043] By arranging a moving block 9 on the outer ring of the inner tube 3 and connecting it to the moving groove 8 on the inner wall of the outer tube 2, this design ensures the stability of the inner tube 3 during movement, effectively prevents the inner tube 3 from shaking or deflecting during movement, thereby improving the accuracy and reliability of the filling operation. The setting of the elastic member 10 enables the moving block 9 to automatically return to its original position after being acted upon by an external force, ensuring that the inner tube 3 can return to its initial state after each filling operation and be ready for the next operation. The stainless steel spring has high strength and corrosion resistance and is suitable for harsh working environments, while the elastic rope has better flexibility and is suitable for occasions with high space requirements. The switch part 4 is connected to the moving block 9 through the connecting shaft 5, and a meshing mechanism of the rack 7 and the gear 6 is arranged in the moving groove 8, thereby realizing precise control of the switch part 4. When the inner tube 3 moves, the interaction between the gear 6 and the rack 7 can ensure that the switch part 4 rotates in a predetermined manner, thereby realizing precise control of the opening and closing of the inner tube 3, improving the accuracy and reliability of the filling operation, and avoiding problems such as leakage or insufficient filling caused by improper operation.

[0044] Reference Figure 2 and Figure 3 The pressurizing part 13 includes: a connecting rod 15, one end of which is installed on the top of the inner tube 3, and the other end passes through the pressurizing part 13; a piston plate 14, which is installed in the pressurizing part 13, and the end of the connecting rod 15 away from the inner tube 3 is connected to the bottom of the piston plate 14; an air inlet pipe 16, which is installed at the bottom of the pressurizing part 13, and the bottom end of the air inlet pipe 16 passes through the filling container 1; an air inlet check valve 17, which is installed on the piston plate 14 and is configured to allow gas to enter the pressurizing part 13 through the air inlet check valve 17 only when the piston plate 14 moves close to the air inlet pipe 16; an air outlet check valve 18, which is installed at the top of the pressurizing part 13 and is configured to allow gas to enter the filling container 1 through the air outlet check valve 18 only when the piston plate 14 is close to the air outlet check valve 18.

[0045] The design of the pressurizing part 13 enables the connecting rod 15 to drive the piston plate 14 to move in the pressurizing part 13 when the inner tube 3 moves, thereby realizing pressure regulation in the filling container 1. Through the coordinated action of the inlet check valve 17 and the outlet check valve 18, it is ensured that the gas can enter or be discharged from the pressurizing part 13 in one direction when the piston plate 14 moves in a specific direction, thereby realizing precise control of the pressure in the filling container 1. The setting of the inlet check valve 17 and the outlet check valve 18 effectively prevents the backflow of gas during the filling process. The inlet check valve 17 ensures that external gas can enter the pressurizing part 13 only when the piston plate 14 moves close to the inlet pipe 16; and the outlet check valve 18 ensures that the gas in the pressurizing part 13 can enter the filling container 1 only when the piston plate 14 is close to the outlet check valve 18. By pressurizing the filling container 1, the filling gas in the filling container 1 can be quickly injected into the transportation pipeline.

[0046] During use, when filling operation is required, the operator sets the outer tube 2 on the transport pipe that needs to be filled, and presses the outer tube 2, so that the transport pipe pushes the inner tube 3 to move in the outer tube 2. As the inner tube 3 moves, the moving block 9 installed on the outer ring of the inner tube 3 also moves in the moving groove 8 on the inner wall of the outer tube 2. During the movement of the moving block 9, the elastic member 10 will be compressed or stretched, thereby providing the moving block 9 with a force pointing to its original position. When the inner tube 3 is disturbed by the outside or the external force disappears, the restoring force of the elastic member 10 can restore the inner tube 3 to its original position. As the inner tube 3 moves further, the connecting rod 15 installed at the top end of the inner tube 3 also moves. The movement of the inner tube 3 will drive the connecting rod 15 and the piston plate 14 to move in the pressurizing part 13. When the piston plate 14 moves toward the direction close to the gas outlet one-way valve 18, the space between the piston plate 14 and the inner wall of the pressurizing part 13 is reduced, and the gas in the pressurizing part 13 is squeezed into the filling container 1, so as to pressurize the filling container 1. During the movement of the inner tube 3, the switch part 4 also rotates, and the connecting shaft 5 drives the gear 6 to roll on the rack 7, so that the switch part 4 rotates in the inner tube 3. This rotation can control the opening and closing of the inner tube 3, and then control the filling operation. After the inner tube 3 is opened, the filling gas in the filling container 1 enters the transport pipeline and completes the filling.

[0047] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0048] By moving the inner tube 3 in the outer tube 2 and combining the rotation control of the switch part 4, the device can achieve precise control of the filling process. The movement of the inner tube 3 can ensure that the filling material enters the filling container 1 stably and continuously, while the rotation of the switch part 4 can accurately control the opening and closing of the filling, thereby improving the efficiency and accuracy of the filling, and the filling device can also be flexibly switched to different transport pipelines for use.

[0049] By the movement of the piston plate 14 in the pressurizing portion 13, automatic pressurization of the filling container 1 is achieved, which ensures that the pressure in the filling container 1 is stable and can provide continuous air supply, thereby ensuring the smooth progress of the filling process.
