Description

Technical Field

[0001] The utility model relates to the field of cleaning the inner wall of a pipe body, in particular to a pipe cleaning device. Background Art

[0002] When cleaning a long metal pipe, such as a straightened copper pipe or steel pipe, a large amount of water droplets will adhere to the inner wall of the pipe after cleaning, which will not evaporate in a short time, and there is a risk of corrosion and oxidation. If natural air drying is used, the crystals precipitated after the cleaning liquid dries will leave water stains on the surface. The existing method is to manually scrape the water droplets from the inner wall of the pipe with a brush. Manual scraping is inefficient and easy to be not scraped clean. Moreover, when the pipe is long, such as when the length of the pipe exceeds 5m, it is difficult to find a suitable brush to completely scrape the water stains on the inner wall. Utility Model Content

[0003] Aiming at the disadvantage that the water droplets attached to the inner wall of the existing long pipe cannot be effectively removed after cleaning, the utility model aims to provide a pipe cleaning device which can effectively remove the water droplets attached to the inner wall of the pipe.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a pipeline cleaning device, comprising a launching tube and a flexible and water-absorbent cleaning ball, the launching tube comprising a boosting chamber and a power storage chamber, one end of the power storage chamber is provided with a launching port, and the other end is connected to the boosting chamber, the boosting chamber is connected to a high-pressure gas source, the cleaning ball located in the boosting chamber can be pushed into the power storage chamber by the high-pressure gas passed into the boosting chamber, and the power storage chamber gradually shrinks toward the launching port so that the cleaning ball can be launched from the launching port with power storage.

[0005] In the technical scheme, the cleaning ball is a flexible and water-absorbing structure, which can effectively remove the water droplets attached to the inner wall of the tube body when it contacts the inner wall of the tube body. The high-pressure gas source passes the high-pressure gas into the boosting chamber, pushing the cleaning ball in the boosting chamber to move forward quickly. The power storage chamber is a structure that is thin in the front and thick in the back, so the flexible cleaning ball collapses inward under the constraint of the inner wall of the power storage chamber. When the diameter of the cleaning ball collapses to the same as the inner diameter of the launch port, the cleaning ball is quickly ejected from the launch port into the inner channel of the tube body under the propulsion of the compressed high-pressure gas in the boosting chamber, forming a power storage launch, and the cleaning ball quickly sweeps the inner channel of the tube body under the action of inertia. The cleaning ball injected into the tube port at one end of the tube body is injected in a collapsed state. In the process of the flexible cleaning ball sweeping the inner wall of the tube body, its own volume will gradually expand. Therefore, while the cleaning ball continuously scrapes off the water droplets attached to the inner wall of the tube body, it also quickly absorbs the scraped water droplets to avoid water droplets from being retained, thereby achieving the purpose of effectively removing the water droplets attached to the inner wall of the tube body.

[0006] The utility model is further configured as follows: the launch device also includes a feeding mechanism, and the feeding mechanism is connected to the power-assisting chamber through an opening, so that the cleaning ball enters the power-assisting chamber through the opening. Through this configuration, the cleaning ball enters the power-assisting chamber from the opening, and the next cleaning ball is dropped after the previous cleaning ball is launched, so that the cleaning ball can be dropped multiple times and the water droplets on the inner wall of the tube body can be cleared. The launch device is not limited to one-time use, so that the supply of cleaning balls becomes automatic, and there is no need to manually place each cleaning ball. Through the feeding mechanism, the cleaning ball can enter the power-assisting chamber according to a predetermined trajectory, avoiding the problem of device failure or poor cleaning effect caused by improper operation or misplacement, and enhancing reliability.

[0007] The utility model is further configured that: the launching device also includes an opening and closing mechanism for opening or closing the opening, so that the boosting chamber behind the cleaning ball can form a closed chamber. The opening is opened and closed by the opening and closing mechanism, so that the boosting chamber behind the cleaning ball can form a relatively closed chamber, which is convenient for the cleaning ball to be ejected under the propulsion of the compressed high-pressure gas in the boosting chamber. The feeding mechanism and the boosting chamber are connected through the opening, so that a cleaning ball can smoothly enter the boosting chamber, reducing the possibility of multiple cleaning balls being blocked or stuck, and improving the launching efficiency of the cleaning balls.

[0008] The utility model is further configured as follows: the feeding mechanism includes a feeding pipe, a piston cavity for arranging the opening and closing mechanism, and a reduced diameter portion arranged between the piston cavity and the opening, and one end of the feeding pipe is connected to the side of the piston cavity. Through this configuration, the cleaning ball enters the power-assisting cavity from the feeding pipe, making it easier to put the cleaning ball in, and avoiding interference between the opening and closing mechanism and the feeding of the cleaning ball.

[0009] The utility model is further configured such that the inner diameter of the reduced diameter portion gradually decreases in the direction close to the opening. The design of the reduced diameter portion makes the opening and the reduced diameter portion as a whole present a bell-mouth shape, which can guide the flow direction of the cleaning ball, so that the cleaning ball can enter the power-assisting cavity more smoothly, reducing obstruction and friction during the flow process.

[0010] The utility model is further configured such that when the cleaning ball is launched with power accumulation, the stroke of the cleaning ball in the boosting chamber is greater than the stroke in the power accumulation chamber. With this configuration, the stroke of the boosting chamber is longer, and the cleaning ball can accumulate enough kinetic energy in the boosting chamber, collapse inwards under the constraint of the inner wall of the power accumulation chamber, and still be launched from the launch port with power accumulation.

[0011] The utility model is further configured that: the launch device also includes a driving mechanism for driving the opening and closing mechanism to open or close the opening. Through this configuration, the driving mechanism controls the opening and closing mechanism to open or close the opening, making the operation of the launch device more automated.

[0012] The utility model is further configured as follows: the feeding mechanism is arranged above the launching tube, and the driving mechanism is arranged above the opening and closing mechanism. The cleaning balls are fed from above, and the driving mechanism is arranged above the opening and closing mechanism to drive the opening and closing mechanism to open or close the opening, making the overall structure more compact and simple.

[0013] The utility model is further configured as follows: the launching device also includes a controller, one end of the boosting chamber is provided with an air intake connector for connecting to a high-pressure gas source, and the driving mechanism and the air intake connector are both connected to the controller. After the cleaning ball enters the boosting chamber, the controller controls the driving mechanism to drive the opening and closing mechanism, so that the opening and closing mechanism closes the opening, and a relatively closed chamber can be formed in the boosting chamber behind the cleaning ball, and high-pressure gas is injected through the air intake connector, so that the cleaning ball can be ejected under the propulsion of the compressed high-pressure gas.

[0014] The utility model is further configured such that the distance between the opening and the air inlet connector is smaller than the distance between the opening and the launch port. With this configuration, the opening is closer to the air inlet connector, the length of the boosting chamber is reduced, thereby reducing the overall length of the launch tube, saving materials, and being more conducive to the boosting chamber behind the cleaning ball to form a relatively closed chamber.

[0015] The advantages of the utility model are: (1) as the cleaning ball sweeps across the inner wall of the tube body, its own volume will gradually expand, so that while the cleaning ball continuously scrapes off the water droplets attached to the inner wall of the tube body, it will also quickly absorb the scraped water droplets, thereby avoiding the retention of water droplets, thereby achieving the purpose of effectively removing the water droplets attached to the inner wall of the tube body; (2) the force storage chamber is a structure that is thin at the front and thick at the back, so that the flexible cleaning ball collapses inwardly under the constraint of the inner wall of the force storage chamber. When the diameter of the cleaning ball collapses to the same diameter as the inner diameter of the launch port, the cleaning ball is rapidly ejected from the launch port into the inner channel of the tube body under the propulsion of the compressed high-pressure gas in the power-assisting chamber, and the cleaning ball rapidly sweeps across the inner channel of the tube body under the action of inertia; (3) the cleaning ball is a flexible and water-absorbent structure, and can effectively remove water droplets attached to the inner wall of the tube body when in contact with the inner wall of the tube body.

[0019] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] In one embodiment of the present invention, the pipeline cleaning device, referring to Figure 1 and Figure 2 , including a launching tube 7 and a flexible and water-absorbent cleaning ball 9, the launching tube 7 including a power-assisting chamber 8 and a power-storing chamber 11, one end of the power-storing chamber 11 is provided with a launching port 12, and the other end is connected to the power-assisting chamber 8, the power-assisting chamber 8 is connected to a high-pressure gas source, the cleaning ball 9 located in the power-assisting chamber 8 can be pushed into the power-storing chamber 11 by the high-pressure gas passed into the power-assisting chamber 8, and the power-storing chamber 11 gradually shrinks toward the launching port 12, so that the cleaning ball 9 can be launched from the launching port 12 with power storage.

[0022] In this embodiment, the cleaning ball 9 is a flexible and water-absorbing structure, and can effectively remove water droplets attached to the inner wall of the tube body 15 when in contact with the inner wall of the tube body 15. The high-pressure gas source passes high-pressure gas into the boosting chamber 8, pushing the cleaning ball 9 in the boosting chamber 8 to move forward rapidly. The power storage chamber 11 is a structure that is thin in the front and thick in the back, so the flexible cleaning ball 9 collapses inward under the constraint of the inner wall of the power storage chamber 11. When the diameter of the cleaning ball 9 collapses to the same diameter as the inner diameter of the launch port 12, the cleaning ball 9 is rapidly ejected from the launch port 12 into the inner channel of the tube body 15 under the propulsion of the compressed high-pressure gas in the boosting chamber 8, and the cleaning ball 9 rapidly sweeps through the inner channel of the tube body 15 under the action of inertia. The cleaning ball 9 injected into the tube opening at one end of the tube body 15 is injected in a collapsed state. During the process of the flexible cleaning ball 9 sweeping across the inner wall of the tube body 15, its own volume will gradually expand. Therefore, the cleaning ball 9 will continuously scrape off the water droplets attached to the inner wall of the tube body 15 while also quickly absorbing the scraped water droplets to avoid the retention of water droplets, thereby achieving the purpose of effectively removing the water droplets attached to the inner wall of the tube body 15.

[0023] It can be understood that the cleaning ball 9 is a sponge ball or other flexible and water-absorbing structure.

[0024] It can be understood that a launching port 12 is provided at one end of the boosting chamber 8 to form a launching end, and the other end forms a boosting chamber tail end 6 , and an air inlet connector 5 is provided on the boosting chamber tail end 6 .

[0025] In one embodiment of the present invention, reference Figure 2 The launching device further includes a feeding mechanism 13, which is connected to the power-assisting chamber 8 through an opening, so that the cleaning ball 9 enters the power-assisting chamber 8 through the opening. The cleaning ball 9 enters the power-assisting chamber 8 from the opening, and the next cleaning ball 9 is released after the previous cleaning ball 9 is launched, so that the cleaning ball 9 can be released multiple times and remove the water droplets on the inner wall of the tube body 15. The launching device is not limited to one-time use, so that the supply of the cleaning ball 9 becomes automatic, and there is no need to manually place each cleaning ball 9. Through the feeding mechanism 13, the cleaning ball 9 can enter the power-assisting chamber 8 according to a predetermined trajectory, avoiding the problem of device failure or poor cleaning effect caused by improper operation or misplacement, and enhancing reliability.

[0026] It can be understood that the inner diameter of the power storage chamber 11 near the launch port 12 is smaller than the diameter of the cleaning ball 9 , and the inner diameter of the power storage chamber 11 near the power assisting chamber 8 is larger than the diameter of the cleaning ball 9 .

[0027] In one embodiment of the present invention, reference Figure 2 The launching device further includes an opening and closing mechanism 14 for opening or closing the opening, so that the boosting chamber 8 behind the cleaning ball 9 can form a closed chamber. By opening and closing the opening by the opening and closing mechanism 14, the boosting chamber 8 behind the cleaning ball 9 can form a relatively closed chamber, which facilitates the ejection of the cleaning ball 9 under the propulsion of the compressed high-pressure gas in the boosting chamber 8. The feeding mechanism 13 and the boosting chamber 8 are connected through the opening, so that a cleaning ball 9 can smoothly enter the boosting chamber 8, reducing the possibility of multiple cleaning balls 9 being blocked or stuck, and improving the launching efficiency of the cleaning balls 9.

[0028] In one embodiment of the present invention, reference Figure 2 The feeding mechanism 13 includes a feeding pipe 3, a piston cavity for arranging an opening and closing mechanism 14, and a reduced diameter portion 4 arranged between the piston cavity and the opening, and one end of the feeding pipe 3 is connected to the side of the piston cavity. The cleaning ball 9 enters the boosting cavity 8 from the feeding pipe 3, making it easier to put the cleaning ball 9, and avoiding interference between the opening and closing mechanism 14 and the feeding of the cleaning ball 9.

[0029] In one embodiment of the present invention, reference Figure 2 The inner diameter of the reduced diameter portion 4 gradually decreases in the direction close to the opening. The design of the reduced diameter portion 4 makes the opening and the reduced diameter portion 4 as a whole in a bell-mouth shape, which can guide the flow direction of the cleaning ball 9, so that the cleaning ball 9 can enter the power-assisting chamber 8 more smoothly, reducing obstacles and friction during the flow process.

[0030] Preferably, when the power is stored and launched, the stroke of the cleaning ball 9 in the boosting chamber 8 is greater than the stroke in the power storage chamber 11. With this arrangement, the stroke of the boosting chamber 8 is longer, and the cleaning ball 9 can accumulate enough kinetic energy in the boosting chamber 8, collapse inward under the constraint of the inner wall of the power storage chamber 11, and still be able to be launched from the launch port 12 with power stored.

[0031] Preferably, the distance between the opening and the air inlet connector 5 is smaller than the distance between the opening and the launch port 12. With this arrangement, the opening is closer to the air inlet connector 5, the length of the boosting chamber 8 is reduced, thereby reducing the overall length of the launch tube 7, saving materials, and being more conducive to the boosting chamber 8 behind the cleaning ball 9 to form a relatively closed chamber.

[0032] In one embodiment of the present invention, reference Figure 2 The launching device further comprises a driving mechanism 1 for driving the opening and closing mechanism 14 to open or close the opening. The driving mechanism 1 controls the opening and closing mechanism 14 to open or close the opening, thereby realizing the automation of the automatic delivery and launching process of the cleaning ball 9, and improving the automation degree and efficiency of the device.

[0033] In one embodiment of the present invention, reference Figure 2 The launching device further includes a controller. One end of the boosting chamber 8 is provided with an air inlet connector 5 for connecting to a high-pressure gas source. The opening and closing mechanism 14 and the air inlet connector 5 are both connected to the controller. After the cleaning ball 9 enters the boosting chamber 8, the controller controls the driving mechanism 1 to drive the opening and closing mechanism 14, so that the opening and closing mechanism 14 closes the opening, and a relatively closed chamber can be formed in the boosting chamber 8 behind the cleaning ball 9. High-pressure gas is injected through the air inlet connector 5, so that the cleaning ball 9 is ejected under the propulsion of the compressed high-pressure gas.

[0034] Preferably, the feeding mechanism 13 is arranged above the launching tube 7, and the driving mechanism 1 is arranged above the opening and closing mechanism 14. The cleaning ball 9 is fed from above, and the driving mechanism 1 is arranged above the opening and closing mechanism 14 to drive the opening and closing mechanism 14 to open or close the opening, making the overall structure more compact and simple.

[0035] Preferably, the feed pipe 3 is arranged tilted downward, and the lower end of the feed pipe 3 is connected to the side of the feed mechanism 13. Due to the tilted design of the feed pipe 3, it is easier to put the cleaning ball 9. The user only needs to put the cleaning ball 9 into the feed pipe 3, and the cleaning ball 9 will slide into the feed mechanism 13 under the action of its own gravity, which simplifies the operation process.

[0036] It can be understood that the driving mechanism 1 can be a telescopic device, or a driving structure such as a cylinder, an electric cylinder, or a motor driving a lead screw.

[0037] In one embodiment of the present invention, reference Figure 1 The end of the tube body 15 close to the launch port 12 is provided with a tube body opening 16, and the inner diameter of the tube body opening 16 is greater than or equal to the inner diameter of the launch port 12. It is convenient for the cleaning ball ejected from the launch port 12 to pass through the tube body opening 16 and enter the tube body 15.

[0038] It can be understood that when the tube body 15 is a copper tube, the cleaning ball 9 can also clean the copper chips in the tube.

[0039] It is understandable that the opening and closing mechanism 14 is a piston. The piston has a simple structure and is easy to maintain and replace.

[0040] It can be understood that the upper end of the feeding mechanism 13 is provided with a piston chamber upper surface 2 , and the driving mechanism 1 passes through the piston chamber upper surface 2 and is connected to the opening and closing mechanism 14 .

[0041] Working principle: the launching port 12 of the launching device is connected and aligned with the tube opening 16 of the tube body 15 to be cleaned, and a dry cleaning ball 9 falls from the feed pipe 3 into the feed mechanism 13 under the action of gravity. The dry cleaning ball 9 leaks from the feed mechanism 13 through the reduced diameter part 4 into the boosting chamber 8 under the action of gravity; the opening and closing mechanism 14 is controlled to descend to the reduced diameter part 4; the high-pressure gas is introduced into the boosting chamber 8 through the air intake joint 5 through an external high-pressure gas source, such as a gas compressor, so that the air pressure between the cleaning ball 9 and the air intake joint 5 rises rapidly, thereby pushing the cleaning ball 9 in the boosting chamber 8 to move forward rapidly. Since the inner diameter of the launching port 12 is smaller than the diameter of the cleaning ball 9, the cleaning ball 9 will be stuck in the launching port 12 during the forward movement and will not move forward further. The cleaning ball 9 stuck in the launching port 12 temporarily forms a relatively closed chamber in the boosting chamber 8. Since the air intake joint 5 is still injecting high-pressure gas The cleaning ball 9 is compressed and then sucked away by the suction force of the suction chamber 11. The suction force of the suction chamber 11 is applied to the suction chamber 12, and the suction force of the suction chamber 12 is applied to the suction chamber 15. The suction force of the suction chamber 11 is applied to the suction chamber 15, and the suction force of the suction chamber 11 is applied to the suction chamber 15.

[0042] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
