Description

Technical Field

[0001] This utility model relates to the field of helium cylinder processing technology, specifically a support for cleaning the inner liner of a helium cylinder. Background Technology

[0002] In the field of industrial gases, helium cylinders are the core containers for storing and transporting high-purity helium, and the cleanliness of their inner liner directly affects the gas quality and filling safety.

[0003] Traditional cleaning of helium cylinder liners relies heavily on manual operation. Operators need to hold a nozzle and reach into the cylinder to rinse it, which is not only inefficient but also poses safety hazards such as limited working space and the risk of bumps and scratches. In addition, manual operation makes it difficult to ensure the consistency of cleaning pressure and angle, resulting in cleaning blind spots in areas such as inner wall corners and cylinder shoulders, which affects the reusability of the cylinder. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bracket for cleaning the inner liner of a helium cylinder, which solves the problems of low cleaning efficiency and poor adaptability of traditional helium cylinder inner liners.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bracket for cleaning the inner liner of a helium cylinder, comprising: a housing, a rotating device slidably connected to the inner wall of the housing, the rotating device being adjustable by sliding, a rinsing device fixedly connected to the inner wall of the housing, and a door rotatably connected to the outer wall of the housing. The rotating device includes a one-way screw, an adjusting rod threadedly connected to the outer wall of the one-way screw, and a pulley assembly rotatably connected to the outer wall of the adjusting rod. The one-way screw and the adjusting rod are threadedly engaged, allowing the adjusting rod to slide by rotating the screw, thereby changing the spacing of the triangular pulley assembly. This design can quickly adapt to helium cylinders of different diameters without replacing parts, improving the bracket's versatility and reducing usage costs.

[0006] Preferably, the bottom end of the one-way screw is symmetrically rotatably connected to the outer wall of the housing, and the outer wall of the adjusting rod is slidably connected to the inner wall of the housing through a sliding groove, wherein the sliding groove is formed on the inner wall of the housing.

[0007] Preferably, a fixed rod is fixedly connected to the end of the pulley assembly away from the adjusting rod, and a sliding rod is fixedly connected to the end of the pulley assembly away from the fixed rod. The pulley assembly is triangular in shape. The outer wall of the fixed rod is rotatably connected to the inner wall of the box through a fixed block, and the outer wall of the fixed block is symmetrically fixed to the outer wall of the box. The outer wall of the sliding rod is slidably connected to the inner wall of the box. The pulley assembly drives the fixed rod and the sliding rod, and combined with the elastic support of the compression spring, it can form a stable clamp for the helium cylinder when adjusting the distance.

[0008] Preferably, a compression spring is fixedly connected to the outer wall of the sliding rod via a connecting block, and the outer wall of the connecting block is rotatably connected to the outer wall of the sliding rod. The end of the compression spring away from the sliding rod is symmetrically fixedly connected to the outer wall of the housing.

[0009] Preferably, the outer walls of the fixed rod and the sliding rod are symmetrically rotatably connected with folding plates. The outer wall of the folding plate is slidably connected to the inner wall of the box. The slidable connection between the folding plate and the box makes the loading and unloading process of the gas cylinder smoother and reduces operation time and manpower consumption.

[0010] Preferably, the rinsing device includes a diversion pipe, with nozzles fixedly connected to the outer wall of the diversion pipe. The outer wall of the diversion pipe is fixedly connected to the inner wall of the housing, and the outer wall of the diversion pipe is arranged in a linear array along the inner wall of the housing. The diversion pipes of the rinsing device are arranged in a linear array along the inner wall of the housing. Multiple nozzles can spray cleaning fluid simultaneously to achieve thorough rinsing of the helium cylinder liner. In conjunction with the rotating device, the cylinder is rotated, further improving cleaning efficiency and cleanliness. Beneficial effects

[0011] This invention provides a support for cleaning the inner liner of a helium cylinder. It has the following advantages: This utility model incorporates a rotating device in which a one-way screw and an adjusting rod are threaded together. Rotating the screw allows the adjusting rod to slide, thereby driving a triangular pulley assembly to change the spacing. This design can quickly adapt to helium cylinders of different diameters without replacing any parts. The pulley assembly drives the fixed rod and the sliding rod, combined with the elastic support of the compression spring, to form a stable clamp on the helium cylinder when adjusting the spacing. At the same time, the sliding connection between the folding plate and the housing makes the loading and unloading of the cylinder smoother. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Please see Figure 1-5 This utility model provides a technical solution: a support for cleaning the inner liner of a helium cylinder, comprising: The inner wall of the box 1 is connected to a rotating device 2, which is adjusted by sliding. The inner wall of the box 1 is fixedly connected to a rinsing device 3, and the outer wall of the box 1 is rotatably connected to a door 4. The object to be cleaned is placed on the outer wall of the rotating device 2 inside the box 1, and then the door 4 is closed and the rinsing device 3 is turned on for rinsing. The rotating device 2 includes a one-way screw 20, an adjusting rod 21 is threadedly connected to the outer wall of the one-way screw 20, a pulley group 22 is rotatably connected to the outer wall of the adjusting rod 21, the bottom end of the one-way screw 20 is symmetrically rotatably connected to the outer wall of the housing 1, and the outer wall of the adjusting rod 21 is slidably connected to the inner wall of the housing 1 through a sliding groove. The sliding groove is opened on the inner wall of the housing 1. When it is necessary to clean helium cylinders of different diameters, the one-way screw 20 can be rotated. The bottom end of the one-way screw 20 is symmetrically rotatably connected to the outer wall of the housing 1. Its threaded transmission characteristics drive the adjusting rod 21 to slide precisely along the sliding groove opened on the inner wall of the housing 1. A fixed rod 23 is fixedly connected to the end of the pulley assembly 22 away from the adjusting rod 21, and a sliding rod 24 is fixedly connected to the end of the pulley assembly 22 away from the fixed rod 23. The pulley assembly 22 is triangular in shape. The outer wall of the fixed rod 23 is rotatably connected to the inner wall of the box 1 through a fixed block, and the outer wall of the fixed block is symmetrically fixed to the outer wall of the box 1. The outer wall of the sliding rod 24 is slidably connected to the inner wall of the box 1. The movement of the adjusting rod 21 will drive the triangular pulley assembly 22 to deform, thereby expanding or shrinking the distance between the fixed rod 23 and the sliding rod 24. This design can be adapted to helium cylinders of different specifications, and no parts need to be replaced during the adjustment process. A compression spring 25 is fixedly connected to the outer wall of the sliding rod via a connecting block, and the outer wall of the connecting block is rotatably connected to the outer wall of the sliding rod. The end of the compression spring 25 away from the sliding rod is symmetrically fixedly connected to the outer wall of the housing 1. A folding plate 26 is symmetrically rotatably connected to the outer walls of the fixed rod 23 and the sliding rod 24. The outer wall of the folding plate 26 is slidably connected to the inner wall of the housing 1. During the spacing adjustment process, the movement of the sliding rod 24 will compress the compression spring 25 connected to its outer wall. The compression spring 25 is rotatably connected to the sliding rod 24 via the connecting block. This connection method ensures that the spring can freely extend and retract, while the fixed rod 23... An elastic clamping force is formed between the fixed rod 23 and the sliding rod 24 to hold the helium cylinder. The folding plate 26, which is symmetrically rotated on the outer wall of the fixed rod 23 and the sliding rod 24, will unfold or retract as the sliding rod 24 moves to prevent water from being discharged from the side wall. The motor on the end face of the fixed rod 23 is started. The output shaft of the motor is coaxially fixedly connected to the fixed rod 23. The motor drives the fixed rod 23 to rotate smoothly. Since the pulley group 22 connects the fixed rod 23 and the sliding rod 24, the rotation of the fixed rod 23 will drive the sliding rod 24 to rotate synchronously through the transmission of the pulley group 22, thereby making the inner liner of the helium cylinder rotate at a set speed.

[0016] The rinsing device 3 includes a diversion pipe 30, with a nozzle 31 fixedly connected to its outer wall. The outer wall of the diversion pipe 30 is fixedly connected to the inner wall of the housing 1, and the outer wall of the diversion pipe 30 is arranged in a linear array along the inner wall of the housing 1. The high-pressure cleaning fluid is sprayed into the inner liner of the gas cylinder through the nozzle 31. The multi-angle layout of the nozzle 31, combined with the annular array of the diversion pipe 30, ensures that the cleaning fluid covers the entire surface of the inner wall of the gas cylinder.

[0017] When in use, place the object to be cleaned on the outer wall of the rotating device 2 inside the box 1, then close the box door 4 and turn on the rinsing device 3 to rinse. First, when it is necessary to clean helium cylinders of different diameters, the one-way screw 20 can be rotated. The bottom end of the one-way screw 20 is symmetrically connected to the outer wall of the housing 1. Its threaded transmission characteristics drive the adjusting rod 21 to slide precisely along the groove opened on the inner wall of the housing 1. The movement of the adjusting rod 21 will drive the triangular pulley group 22 to deform, thereby expanding or shrinking the distance between the fixed rod 23 and the sliding rod 24. This design can be adapted to helium cylinders of different specifications, and no parts need to be replaced during the adjustment process. During the spacing adjustment process, the movement of the sliding rod 24 will compress the compression spring 25 connected to its outer wall. The compression spring 25 is rotatably connected to the sliding rod 24 through the connecting block. This connection method ensures that the spring can freely extend and retract, forming an elastic clamping force on the helium cylinder between the fixed rod 23 and the sliding rod 24. The folding plate 26, which is symmetrically rotatably connected to the outer walls of the fixed rod 23 and the sliding rod 24, will unfold or retract as the sliding rod 24 moves, preventing water from being discharged from the side wall.

[0018] After the gas cylinder is secured, start the motor on the end face of the fixing rod 23. The motor output shaft is coaxially and fixedly connected to the fixing rod 23. The motor drives the fixing rod 23 to rotate smoothly. Since the pulley group 22 connects the fixing rod 23 to the sliding rod 24, the rotation of the fixing rod 23 will drive the sliding rod 24 to rotate synchronously through the transmission of the pulley group 22, thereby making the inner liner of the helium cylinder rotate at a set speed.

[0019] Meanwhile, the diversion pipes 30 are arranged in a linear array along the inner wall of the housing 1, and the high-pressure cleaning fluid is sprayed into the inner liner of the gas cylinder through the nozzles 31. The multi-angle layout of the nozzles 31, together with the annular array of the diversion pipes 30, ensures that the cleaning fluid covers the entire surface of the inner wall of the gas cylinder.
