[0001] This utility model relates to the field of liquid conveying equipment technology, and in particular to a retractable pipeline liquid injection device. Background Technology

[0002] In many fields such as industrial production, construction, and healthcare, pipeline liquid injection is a common process. Traditional pipeline liquid injection devices typically use fixed-length pipes for liquid transport, a design with several limitations. For example, when injecting liquid into target containers of varying depths or heights, fixed-length pipes often fail to meet requirements, forcing operators to frequently change pipes of different lengths or adjust equipment positions, significantly reducing work efficiency. Furthermore, traditional devices lack effective stroke monitoring and collision protection measures during liquid injection, making them susceptible to damage from excessive pipe expansion or contraction or collisions, potentially leading to safety accidents, unnecessary economic losses, and personal injury.

[0024] Example 1

[0025] Please refer to Figure 1This utility model provides a retractable pipeline injection device, including a vertically arranged fixed pipe 1. The fixed pipe 1 is a hollow tubular structure, serving as the fixing base of the device, and is made of 304 stainless steel, possessing corrosion resistance and structural stability. A movable pipe 2 is movably sleeved at the bottom end of the fixed pipe 1. The movable pipe 2 is also made of 304 stainless steel, and its inner diameter is slightly larger than the outer diameter of the fixed pipe 1. A drive mechanism 3, which is pulsatorically connected to the movable pipe 2, is provided at the top of the fixed pipe 1 to drive the movable pipe 2 to move up and down along the fixed pipe 1.

[0026] A monitoring mechanism 4 is fixedly installed on one side of the fixed tube 1 to monitor the maximum upward and downward strokes of the movable tube 2, ensuring that the movable tube 2 moves within a safe range and preventing equipment damage caused by excessive extension or retraction. An anti-collision mechanism 5 is installed at the bottom of the fixed tube 1, which effectively prevents the movable tube 2 from colliding with the target container or other objects during descent, protecting the equipment and operators. The drive mechanism 3, monitoring mechanism 4, and anti-collision mechanism 5 are all electrically connected to a local control box 6, which integrates a controller and a touchscreen.

[0027] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0028] Example 2

[0029] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in:

[0030] like Figure 1 As shown, the driving mechanism 3 includes a lead screw 31, which is coaxially disposed within the fixed tube 1 and the movable tube 2. The diameter of the lead screw 31 is much smaller than the inner diameter of the fixed tube 1 and the movable tube 2. A support plate 32 is fixedly disposed at the top end of the fixed tube 1, completely covering the opening at the top end of the fixed tube 1, and it plays an important supporting and positioning role. A first bracket 33 is fixedly disposed at the bottom end of the movable tube 2 to support and fix the bottom end of the lead screw 31. The bottom end of the lead screw 31 is rotatably connected to the first bracket 33 through a bearing, which ensures that the lead screw 31 can rotate freely within the first bracket 33 while maintaining stability and accuracy. The top end of the lead screw 31 passes through the support plate 32 and extends out from above the support plate 32.

[0031] A turbine is rotatably connected to the support plate 32 via a bearing seat. The turbine is threadedly connected to the lead screw 31. When the turbine rotates, the interaction of the threads drives the lead screw 31 to rotate as well. A worm gear is meshed with one side of the turbine. The rotation of the worm gear drives the turbine to rotate through the meshing relationship. A drive motor 34 that drives the worm gear is fixedly installed on one side of the support plate 32. Specifically, when the drive motor 34 starts and runs, it drives the worm gear to rotate, which in turn drives the turbine gear to rotate through the meshing transmission between the worm gear and the turbine gear. Finally, the rotation of the lead screw 31 is achieved through the threaded connection between the turbine gear and the lead screw 31. The entire drive mechanism 3 converts the power of the motor into the rotational motion of the lead screw 31 through this mechanical transmission method, thereby realizing the driving and control of the movable tube 2.

[0032] A casing 35, covering the turbine and worm gear, is fixedly mounted on the support plate 32. Its main function is to completely enclose the turbine and worm gear, forming a closed protective space. The casing 35 has a compact design and excellent sealing performance, preventing external dust, impurities, and liquids from entering the transmission area of ​​the turbine and worm gear, thereby ensuring the normal operation and service life of the transmission components. The casing 35 is typically made of high-strength metal or engineering plastic, possessing good wear resistance and corrosion resistance. The top end of the lead screw 31 extends through the casing 35. A through hole is provided at the top of the casing 35 for the lead screw 31 to pass through. The through hole is specially treated to ensure sealing while allowing the lead screw 31 to rotate freely.

[0033] A sealing sleeve 36 is fitted onto the lead screw 31 inside the fixed tube 1. The inner diameter of the sealing sleeve 36 is slightly larger than the diameter of the lead screw 31, and the outer diameter of the sealing sleeve 36 is much smaller than the inner diameter of the fixed tube 1. A second bracket 37 is fixedly installed at the bottom end of the fixed tube 1. The bottom end of the sealing sleeve 36 is fixedly connected to the second bracket 37. The second bracket 37 is an important support component fixed at the bottom of the fixed tube 1. It not only provides stable support for the sealing sleeve 36, but also plays a role in positioning and fixing it. By firmly connecting the bottom end of the sealing sleeve 36 to the second bracket 37, the stability and reliability of the sealing sleeve 36 within the entire fixed tube 1 are ensured.

[0034] The top end of the sealing sleeve 36 is fixedly connected to the support plate 32, which can prevent other impurities from entering the gap between the lead screw 31 and the sealing sleeve 36. A sealing ring is provided between the bottom end of the sealing sleeve 36 and the lead screw 31. The sealing ring is used to prevent liquid in the fixed tube 1 from flowing into the gap between the lead screw 31 and the sealing sleeve 36, causing the lead screw 31 to rust. The sealing ring is usually made of high-performance elastic material with good wear resistance, corrosion resistance and elastic recovery ability. This material can maintain a tight sealing contact when the lead screw 31 rotates, without causing excessive wear to the lead screw 31.

[0035] The parts of the lead screw 31 that slide in contact with the sealing ring are all smooth, meaning their surfaces are free of threads or other protrusions. This smooth design reduces frictional resistance between the lead screw 31 and the sealing ring, ensuring smooth rotation of the lead screw 31 and facilitating better contact between the sealing ring and the lead screw 31 surface for a superior seal. This design allows the lead screw 31 to maintain efficient and stable operation during rotation, thus ensuring the sealing performance and reliability of the entire drive mechanism 3.

[0036] Example 3

[0037] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in:

[0038] The monitoring mechanism 4 includes a high-position switch 41 and a low-position switch 42. A vertical rod 43 is provided on the outside of the fixed tube 1 and the movable tube 2. The vertical rod 43 is parallel to the axis of the fixed tube 1 and provides a basis for the setting position of the high-position switch 41 and the low-position switch 42. The top of the vertical rod 43 is fixedly connected to the fixed tube 1 through a horizontal rod 44. This connection not only provides sufficient support but also ensures that the relative position between the vertical rod 43 and the fixed tube 1 is stable and will not be shifted due to external force.

[0039] The high-position switch 41 is fixedly installed at the top of the vertical rod 43 near the fixed tube 1. When the movable tube 2 moves upward to the highest position, the high-position switch 41 can be triggered, thereby sending a signal to the controller and immediately stopping the rotation of the drive motor 34 to prevent the movable tube 2 from colliding or other accidents due to excessive rising.

[0040] The low-position switch 42 is fixedly installed at the bottom end of the vertical rod 43 near the fixed tube 1. When the movable tube 2 moves down to the lowest position, the low-position switch 42 can be triggered, thereby sending a signal to the controller and immediately stopping the rotation of the drive motor 34, preventing the movable tube 2 from colliding or other accidents due to excessive descent.

[0041] Through the coordinated action of the high-position switch 41 and the low-position switch 42, precise monitoring and control of the movement range of the movable tube 2 are achieved, thereby improving the safety and reliability of the entire device.

[0042] The anti-collision mechanism 5 includes an anti-collision ring 51 located below the movable tube 2. The main function of the anti-collision ring 51 is to act as the first line of defense, preventing the movable tube 2 from directly colliding with other components during its descent. Several fixing blocks 52 are evenly distributed around the outer periphery of the bottom end of the movable tube 2. There are four fixing blocks 52, which are uniformly fixed to the outer wall of the movable tube 2, providing support and connection. Each fixing block 52 is slidably fitted with a sliding rod 53, which can slide up and down within the fixing block 52, thus providing a certain amount of movement space for the anti-collision ring 51. A limit cap 54 is fixedly installed at the top of each sliding rod 53. The limit cap 54 prevents the sliding rod 53 from slipping out of the fixing block 52, ensuring the stability of the sliding rod 53. The bottom end of each sliding rod 54 is fixedly connected to the anti-collision ring 51, allowing the anti-collision ring 51 to move up and down with the movement of the sliding rod 53.

[0043] An anti-collision switch 55 is fixedly installed on the outer wall of the movable tube 2 above any of the limiting end caps 54. When the movable tube 2 descends to a certain extent and the anti-collision ring 51 contacts other components, the slide rod 53 will be subjected to an upward force, thereby driving the limiting end cap 54 to move upward. When the limiting end cap 54 contacts the anti-collision switch 55, the anti-collision switch 55 will be triggered, sending a signal to the controller and controlling the stop of the rotation of the drive motor 34, so that the movable tube 2 will no longer move downward. The anti-collision mechanism 5 can form an effective buffer and protection between the movable tube 2 and other components, greatly reducing the risk of collision and improving the safety and service life of the device.

[0044] Example 4

[0045] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in:

[0046] A horizontally extending water inlet pipe 7 is provided on one side of the top end of the fixed pipe 1. The water inlet pipe 7 introduces external water into the fixed pipe 1, providing the necessary liquid medium for the device. The free end of the water inlet pipe 7 is the water inlet 71, which is the inlet position of the liquid water inlet pipe 7. The water inlet pipe 7 is connected to the fixed pipe 1 and is welded together to ensure that the liquid can flow smoothly from the water inlet pipe 7 into the fixed pipe 1, while also preventing liquid leakage at the connection point.

[0047] An electric valve 72 is installed on the water inlet pipe 7. The electric valve 72 is opened and closed by a controller. A liquid level sensor 8 is fixedly installed on one side of the bottom end of the movable pipe 2. The liquid level sensor 8 is used to monitor the liquid level in the target container in real time. Both the electric valve 72 and the liquid level sensor 8 are electrically connected to the local electrical control box 6. When the liquid level in the target container triggers the liquid level sensor 8, the liquid level sensor 8 sends a signal to the controller and controls the electric valve 72 to close.

[0048] A flow meter 73 is installed on the water inlet pipe 7 between the electric valve 72 and the water inlet 71. The flow meter 73 is used to measure the liquid flow rate entering the fixed pipe 1 in real time. The operator can accurately control the liquid inflow rate to ensure that the liquid supply meets the capacity standard of the target container.

[0049] The operation of the pipeline injection device is as follows: The operator starts the device through the local electrical control box 6. The drive motor 34 starts rotating, which drives the worm gear to rotate. Through the meshing connection between the worm and the worm, the lead screw 31 rotates, causing the movable tube 2 to move downwards into the target container. When the movable tube 2 moves to the predetermined position, the low-position switch 42 is triggered, and the low-position switch 42 sends a signal to the controller. The controller then stops the rotation of the drive motor 34 and opens the electric valve 72 to start injection. The liquid level sensor 8 monitors the liquid level in the target container in real time. When the liquid level reaches the preset height, the controller controls the electric valve 72 to close, thus stopping the injection. During the injection process, the flow meter 73 measures the liquid flow rate in real time and transmits the data to the controller. The controller adjusts the opening of the electric valve 72 according to the flow rate data to ensure that the injection speed meets the requirements. When it is necessary to adjust the position of the movable tube 2, the controller controls the rotation direction and speed of the drive motor 34 according to the data from the liquid level sensor 8, causing the movable tube 2 to move up and down. After completing the liquid injection task, the operator stops the operation of the device through the local electrical control box 6, closes the electric valve 72 and the drive motor 34, and the device enters the standby state.
