Description

[0002] In the fields of chemical industry, petroleum, natural gas, etc., circular pipes are often used to transport oil, gas and other substances. However, since the pipes are not only slender and narrow, but also have curved parts, it is inconvenient to inspect and repair the pipes (rust and paint repair). At present, the diameter-changing mechanisms of pipeline devices on the market are generally simple, and most pipeline peristaltic devices do not even have diameter-changing mechanisms, which means that they can only deal with pipes of a single diameter, greatly limiting the scope of application and passability. Even for three-phase stereoscopic devices with a certain diameter-changing mechanism, generally an integrated drive mechanism is built into the device, and the entire line, power supply, circuit board, etc. are integrated into one. The structure is relatively limited, assembly is inconvenient, and the subsequent maintenance and use costs are high. If problems occur in the pipe for a long time, it is easy to shut down inside and difficult to remove.

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] See attached Figure 1 As shown, a robot for repairing the inner wall of a bent pipe based on external driving force operation, wherein the repairing device 2 is built into and applied to a thin tube 1, and its external driving force is driven by a simple water pressure, which is pumped into one side of the thin tube 1 through a water pump 1 01, and the remaining water from the repairing device 2 is quickly pumped out to a water tank 3 on the other side of the thin tube 1 through a water pump 2 02, and the two form a water circulation.

[0026] See attached Figure 2-4 As shown, the repair device 2 includes a connecting main pipe 31, and the front side of the connecting main pipe 31 is sleeved with a blocking member through a support rod 16 connected circumferentially to the periphery, which is used to block the water pumped in by the water pump and form an external driving force to propel the entire repair device 2 while being subjected to the impact force of the water.

[0027] The rear side of the connecting main pipe 31 is connected to the wind rotor frame 11, wherein a sleeve 14 is pivotally connected to the connecting main pipe 31, and a plurality of long rods 13 are circumferentially connected to the sleeve 14, and the long rods 13 are respectively connected to the circumferential edge of the rear side of the wind rotor frame 11. The rear end of the connecting main pipe 31 is connected to a transverse pipe 32, and the side end of the transverse pipe 32 is connected to an L-shaped water outlet pipe 33, and the water outlet end of the L-shaped water outlet pipe 33 is located at the built-in side of the wind rotor frame 11, and the water outlet of the L-shaped water outlet pipe 33 to the wind rotor frame 11 can drive it to rotate along the axial direction of the connecting main pipe 31 by discharging water from the L-shaped water outlet pipe 33 to the wind rotor frame 11.

[0028] The wind wheel frame 11 adopts a conventional structural design, and the principle can be referred to as a waterwheel. The function of the horizontal pipe 32 is to stagger the position of the L-shaped water outlet pipe 33 so that the falling water can fall into the edge of the wind wheel frame 11 to stagger the center of gravity and realize driving. It should be noted that the entire wind wheel frame 11 is light in weight and can rotate under the drive of the water flow. In addition, a through groove 12 is provided on the wind wheel frame 11, which can quickly drain water into the capillary 1 during the rotation process.

[0029] A spraying mechanism 10 is circumferentially provided on the outer peripheral wall of the wind wheel frame 11. The spraying mechanism 10 is used for repairing and adopts conventional components, such as a micro pump, a nozzle, a liquid storage chamber and a battery.

[0030] In order for the spray mechanism 10 to spray the inner wall of the capillary 1 , the axial outer diameter of the wind wheel frame 11 is smaller, specifically, the radius of the wind wheel frame 11 plus the height of the spray mechanism 10 is smaller than the radius of the inner wall of the capillary 1 .

[0031] From the above, it can be seen that the rear side of the entire repair device 2 is suspended relative to the inner wall of the pipe. Taking into account the rear wind wheel frame 11, the spraying mechanism 10 and the water flow, it is easy for the rear side to be heavier than the front side and flip down. Therefore, a sleeve frame 15 is set in the middle of the connecting main pipe 31, and brackets 9 are connected to both sides of the bottom of the sleeve frame 15. Rollers are set on the bracket 9 to achieve support and smooth movement.

[0032] When in use, the water pressure pumped by the water pump 1 01 should not be too large, and it is sufficient to drive the repair device 2 to move forward as a whole. Part of the water source is pumped into the connecting main pipe 31 and output to the L-shaped water outlet pipe 33, forming a water flow to drive the wind wheel frame 11 to rotate. At the same time, the water pump 2 02 needs to be turned on all the time to keep the pipe section that the repair device 2 has not passed through as dry as possible.

[0033] See attached Figure 5 As shown, the blocking member includes a blocking frame 4, on which sleeves 17 are fixed at equal intervals in the circumferential direction, and a rotating seat 7 is rotatably connected to the sleeve 17, and a U-shaped rod 8 is hinged between two adjacent rotating seats 7. By rotating one of the rotating seats 7, the entire rotating seat 7 is linked to rotate, and the U-shaped rod 8 is driven to gradually expand outward to the periphery of the blocking frame 4. The front side of the U-shaped rod 8 is wrapped with a flexible curtain 5, which is made of conventional flexible material and has elastic deformation force. Driven by the U-shaped rod 8, it is stretched outward to block the water flow and indirectly form the propulsion force of the repair device 2 as a whole. Secondly, the inner periphery of the curtain 5 is wrapped around the outer pipe wall of the connecting main pipe 31.

[0034] Since the curtain 5 is easily deformed and spread backwards due to water pressure, a support rod 16 slightly inclined forward is arranged on the inner circumference of the blocking frame 4 to form a buffer for the front blocking force of the curtain 5 .

[0035] The arrangement of the rotating seat 7, the U-shaped rod 8 and other structures can indirectly drive the curtain 5 to expand its circumferential dimension to fit the inner wall of the capillary 1 as closely as possible, thereby achieving the adaptation and use of capillary 1 with different diameters.

[0036] See attached Figure 6As shown, a gear 18 is arranged at a rotating seat 7 at the bottom, a hole slot is opened on the blocking frame 4, a spring 21 is arranged on the hole slot, and a connecting column 19 is connected to the upper end of the spring 21, a limit block 20 is sleeved on the connecting column 19, and the limit block 20 is normally pressed into the adjacent tooth groove on the gear 18. When rotation is required, the connecting column 19 can be pulled up to drive the limit block 20 to disengage from the gear 18, thereby realizing the rotation adjustment of the rotating seat 7.

[0037] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
