Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning, and in particular relates to a ball collecting cylinder buffer device for a natural gas pipeline. Background Art

[0002] Natural gas pipeline rubber ball cleaning is a technology used to remove dirt and sediments in natural gas pipelines. This technology uses a special rubber ball to pass through the inside of the pipeline, and uses the friction and elasticity between the rubber ball and the pipe wall to remove dirt from the pipe wall, thereby achieving the purpose of cleaning the pipeline.

[0003] For example, the Chinese patent with the announcement number CN219851198U discloses a pipeline ball collector, wherein a ball-blocking pipe joint is detachably mounted on the bottom of the ball collector, and a blocking plate is provided between the ball-blocking pipe joint and the ball collector, and a buffer and a first through hole for discharging liquid are provided on the blocking plate, and the buffer is a buffer pad, and a second through hole opposite to the first through hole is provided on the buffer pad. The technical solution in this patent can reduce shock by using the blocking plate and the buffer, but because the speed of cleaning the rubber ball is relatively fast, the rubber ball is only blocked by the blocking plate while the buffer pad is used for shock reduction. After shock reduction, the rubber ball will rebound and reciprocate against the inner wall of the ball collector, resulting in the inability to quickly discharge the ball collector. In view of this, we propose a buffer device for a natural gas pipeline ball collector. Utility Model Content

[0023] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0024] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0025] The embodiment of the present application discloses a natural gas pipeline ball collecting cylinder buffer device, comprising a connecting pipe 1, a buffer box 2, the buffer box 2 is connected to and passes through the rear end of the connecting pipe 1, an articulated shaft 3 is fixedly installed at one end of the buffer box 2 away from the connecting pipe 1, a symmetrically arranged articulated rod 4 is articulated on the outer surface of the articulated shaft 3, and a roller 5 is rotatably connected to the articulated rod 4 close to the end of the connecting pipe 1, a support platform 6 is fixedly installed at one end of the buffer box 2 away from the connecting pipe 1, an annular elastic telescopic sleeve 7 is fixedly installed at the front end of the support platform 6, and the free ends of the annular elastic telescopic sleeve 7 are respectively fixedly connected to the articulated rod 4, and an outlet 13 is opened at the bottom end of the buffer box 2.

[0026] Based on the above structure,

[0027] In one of the embodiments, electromagnetic blocks 8 are fixedly installed on both sides of the support platform 6, a magnetic plate 9 is fixedly installed on the side where the hinged rods 4 are close to each other, a coil 10 is fixedly installed on the front end of the support platform 6, and a magnetic needle 11 is fixedly installed on the side where the hinged rods 4 are close to each other. The magnetic needle 11 is sleeved inside the coil 10. Through such an arrangement, when the hinged rod 4 swings, the magnetic needle 11 moves in the coil 10 to generate an electrical signal. After a period of time, the electromagnetic block 8 is driven to be energized, thereby increasing the distance between the two rollers 5 to avoid the rubber ball from being unable to squeeze the roller 5 due to low power and resulting in accumulation in the connecting tube 1.

[0028] Based on the above structure,

[0029] In one of the embodiments, a baffle 12 is fixedly installed in the middle of the outer surface of the hinge shaft 3. The baffle 12 is semi-circular in shape, and the middle of the baffle 12 is fixedly connected to the hinge shaft 3. The baffle 12 can achieve a certain shock-absorbing effect.

[0030] Specifically, a flange plate 14 is fixedly installed at one end of the connecting pipe 1 away from the buffer box 2. The diameters of the flange plate 14 and the connecting pipe 1 are the same as the diameter of the rubber ball. The diameter of the outlet 13 is larger than the diameter of the connecting pipe 1. Through this arrangement, there is enough space for the rubber ball to be discharged.

[0031] Based on the above structure,

[0032] In one embodiment, a separation tube 15 is fixedly installed at the bottom end of the outlet 13, an arc-shaped filter plate 16 is inserted at the bottom end of the separation tube 15, and a collecting sleeve 17 is inserted below the outer surface of the separation tube 15. This arrangement can achieve separation of the rubber ball and the liquid brought out by the rubber ball.

[0033] Specifically, the center line of the upper roller 5 is located below the upper tangent line of the inner diameter of the connecting tube 1, and the two rollers 5 are symmetrically arranged. Such an arrangement can ensure that the rollers 5 can hinder the movement of the rubber ball.

[0034] Specifically, the distance between the roller 5 and the baffle 12 is greater than the inner diameter of the connecting tube 1 , and the distance between the two symmetrical hinge rods 4 is greater than the inner diameter of the connecting tube 1 . This arrangement can prevent the rubber ball from getting stuck in the space.

[0035] Specifically, the annular elastic telescopic sleeve 7 includes a fixed ring 701, and grooves 702 are provided at both ends of the fixed ring 701. The interior of the groove 702 is slidably connected to a semi-ring block 703, and the semi-ring block 703 is fixedly connected to the hinge rod 4. The semi-ring block 703 is fixedly connected to the inner wall of the groove 702 by a reset spring 704. Such an arrangement can ensure that the hinge rod 4 can be reset under the action of the reset spring 704.

[0036] When a natural gas pipeline ball collecting cylinder buffer device of the present embodiment is used, the device is connected to the cleaning pipeline. When the rubber ball passes through the connecting pipe 1, it can impact the roller 5, thereby squeezing the hinged rod 4 to swing. When the kinetic energy of the rubber ball is large enough, it rushes through the two rollers 5 and collides with the baffle 12 and falls from the outlet. When the kinetic energy of the rubber ball is not large enough, it only squeezes the hinged rod 4 to swing in a small range but is not enough to pass through the two rollers 5. Due to the squeezing of the hinged rod 4 to swing in a small range, the magnetic needle 11 moves in the coil 10 to generate an electrical signal, and the driving electromagnetic block 8 is energized to squeeze the magnetic plates 9 on both sides, thereby increasing the distance between the two rollers 5 to facilitate the passage of the rubber ball, thereby effectively buffering the rubber ball.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
