[0002] Pipeline corrosion prevention usually refers to measures to slow down or prevent the corrosion and deterioration of pipelines under the chemical and electrochemical effects of internal and external media or the metabolic activities of microorganisms. In addition to the post-maintenance of pipelines, adding coatings to the pipeline surface is a major anti-corrosion method. However, for areas where corrosion has already occurred, the coating on the pipeline surface may accelerate the corrosion rate, so it is necessary to remove the old coating of the pipeline.

[0003] The existing methods for removing the anti-corrosion layer on the surface of pipelines are usually manual grinding or mechanical methods. Manual grinding relies on workers to hold grinding tools, which is extremely labor-intensive, and the grinding quality depends entirely on the workers' experience. It is very easy to have uneven grinding and low efficiency. Although mechanical grinding can improve efficiency, traditional grinding equipment is mostly single-function and can only perform grinding operations. During the grinding process, the high-speed rotating grinding disk and the pipeline anti-corrosion layer rub violently, which will generate a lot of heat, which not only accelerates the wear of the grinding disk, but may also cause changes in the material properties of the pipeline surface due to overheating. Therefore, there is an urgent need for a pipeline anti-corrosion construction device with an anti-corrosion layer removal component to solve this problem. Summary of the invention

[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] A pipeline anti-corrosion construction device with an anti-corrosion layer removal component comprises: a cleaning component 30, wherein the cleaning component 30 comprises a water storage tank 31 and a rotating shaft 34 coaxially rotatably plugged into the water storage tank 31, an expansion portion 38 is integrally formed on the surface of the rotating shaft 34 and located inside the water storage tank 31, and a plurality of groups of water inlet holes 381 corresponding to each other are provided on the top and bottom of the expansion portion 38, a crankshaft 33 is fixedly provided on one end of the rotating shaft 34 extending to the outside of the water storage tank 31, a mounting plate 36 is fixedly provided on the other end of the rotating shaft 34 extending to the outside of the water storage tank 31, a grinding plate 35 is fixedly provided on the bottom of the mounting plate 36, a cooling chamber connected to the cavity of the rotating shaft 34 is provided in the grinding plate 35, a plurality of groups of water outlet holes 37 connected to the cooling chamber are provided at the bottom of the mounting plate 36 and located around the grinding plate 35, and the internal cavity of the rotating shaft 34 connects the water storage tank 31 with the cooling chamber through the water inlet hole 381 to form a cooling water passage; A pumping assembly 40, the pumping assembly 40 comprises a cylinder 41 fixedly arranged on the top of the water storage tank 31, a pumping member movably inserted in the cylinder 41, and a connecting rod 44 arranged between the pumping member and the crankshaft 33, and a unidirectional air inlet pipe 48 and an air outlet pipe 47 are respectively arranged on the top of the cylinder 41 and away from the crankshaft 33, and the air outlet pipe 47 is communicated with the water storage tank 31; The crankshaft 33 is driven to rotate by an external force, and the pumping member is controlled to reciprocate in the cylinder 41 through the connecting rod 44, so that the cylinder 41 is filled with air through the air inlet pipe 48 and the gas in the cylinder 41 is compressed into the water tank 31 through the air outlet pipe 47.

[0016] Specifically, when an external force drives the crankshaft 33 to rotate, the crankshaft 33 drives the rotating shaft 34 to rotate together, and the rotating shaft 34 drives the grinding disc 35 to rotate together, and the rotating grinding disc 35 contacts the anti-corrosion layer of the pipeline, and grinds the anti-corrosion layer through friction, thereby achieving the purpose of removing the anti-corrosion layer; Before grinding, there is a proper amount of water in the water tank 31. During grinding, the internal cavity of the rotating shaft 34 connects the water tank 31 with the cooling chamber through the water inlet hole 381, forming a cooling water passage. During the operation of the device, the cooling water can flow in this passage to take away the heat generated during the grinding process. The cooling water in the cooling chamber finally flows out through the water outlet hole 37 and sprays onto the surface of the pipe, which can remove the waste on the surface of the pipe, improve the accuracy and uniformity of grinding, and reduce the heat generated by the friction between the grinding disc 35 and the surface of the pipe. Because the temperature is too high, the thermal stress will cause the material properties of the surface of the pipe to change, or even deform. The crankshaft 33 drives the pumping member to move. When the crankshaft 33 is driven to rotate by an external force, the crankshaft 33 is rotatably connected to the connecting rod 44 through a fixed sleeve. The other end of the connecting rod 44 is rotatably connected to the pumping member. The rotation of the crankshaft 33 causes the connecting rod 44 to swing, thereby controlling the pumping member to reciprocate in the cylinder 41. Cylinder filling process: reference Figure 6 as well as Figure 7 When the pumping member moves in the cylinder 41 toward the crankshaft 33, the space in the cylinder 41 and between the pumping member and the intake pipe 48 increases, the air pressure decreases, and a negative pressure is formed. Since the intake pipe 48 is a unidirectional flow, the outside air will enter the cylinder 41 through the intake pipe 48, and the cylinder 41 is filled with air. Cylinder deflation process: reference Figure 4 as well as Figure 5 When the pumping member moves in the cylinder 41 in a direction away from the crankshaft 33, the space in the cylinder 41 and between the pumping member and the air inlet pipe 48 decreases, and the air pressure increases. At this time, the one-way air inlet pipe 48 prevents the gas from flowing back, and the gas in the cylinder 41 is compressed into the water storage tank 31 through the air outlet pipe 47; The gas compressed into the water tank 31 increases the pressure in the water tank 31, causing the cooling water in the water tank 31 to enter the internal cavity of the rotating shaft 34 through the water inlet hole 381, then flow into the cooling chamber of the grinding disc 35, and finally flow out from the water outlet hole 37, forming a stable cooling water circulation to ensure continuous cooling during the grinding process. This cycle is repeated to continuously provide cooling water for the grinding process to ensure the normal operation of the device.

[0017] In one embodiment, the pumping member includes a pumping cylinder 42 movably disposed in the cylinder 41 and a piston 43 slidably disposed inside the pumping cylinder 42, the piston 43 is rotatably connected to the connecting rod 44, the end of the pumping cylinder 42 away from the crankshaft 33 passes through the end of the cylinder 41 and extends to the outside of the cylinder 41, the end of the pumping cylinder 42 extending to the outside of the cylinder 41 is respectively connected to a water inlet pipe 46 and a water outlet pipe 45 provided with unidirectional flow, and the end of the water outlet pipe 45 away from the pumping cylinder 42 is connected to the water storage tank 31; The friction between the piston 43 and the water pumping cylinder 42 is greater than the friction between the water pumping cylinder 42 and the cylinder 41. A limit ring 411 is provided inside the cylinder 41 and at one end close to the air inlet pipe 48. Specifically, the end of the water inlet pipe 46 away from the water pumping cylinder 42 is inserted into the water tank 50. When the crankshaft 33 rotates, the piston 43 is driven to move through the connecting rod 44. Since the friction between the piston 43 and the water pumping cylinder 42 is greater than the friction between the water pumping cylinder 42 and the cylinder 41, in the initial stage, the piston 43 will drive the water pumping cylinder 42 to move in the cylinder 41 in the direction away from the crankshaft 33. When the water pumping cylinder 42 moves to contact with the limit ring 411, the movement of the water pumping cylinder 42 is restricted and stops. At this time, since the crankshaft 33 continues to rotate, the connecting rod 44 will continue to drive the piston 43 to move in the water pumping cylinder 42 in the direction away from the crankshaft 33. Figure 4 as well as Figure 5 At this time, the space in the pumping cylinder 42 and between the piston 43 and the water inlet pipe 46 is reduced. At this time, the one-way valve of the water inlet pipe 46 prevents water from flowing out, and the water in the pumping cylinder 42 is pressed out through the water outlet pipe 45 and transported to the water storage tank 31 under the action of pressure; As the crankshaft 33 continues to rotate, the connecting rod 44 drives the piston 43 to move in the water pumping cylinder 42 toward the direction close to the crankshaft 33. Since the friction between the piston 43 and the water pumping cylinder 42 is greater than the friction between the water pumping cylinder 42 and the cylinder 41, in the initial stage, the piston 43 drives the water pumping cylinder 42 to move in the cylinder 41 toward the direction close to the crankshaft 33. When the end of the water pumping cylinder 42 contacts the cylinder 41 to limit the position, the piston 43 continues to move inside the water pumping cylinder 42, so that the area between the piston 43 and the water inlet pipe 46 increases, forming a negative pressure. Figure 6 as well as Figure 7 Since the water inlet pipe 46 is unidirectional, under the action of negative pressure, the water in the water tank 50 will be sucked into the water pumping cylinder 42 through the water inlet pipe 46. At this time, the one-way valve of the water outlet pipe 45 prevents water from flowing back, ensuring that water can only enter from the water inlet pipe 46. By continuously transporting the water in the water tank 50 to the water storage tank 31, it is ensured that there is always enough cooling water in the water storage tank 31, which provides a guarantee for the continuous operation of the cleaning component. The stable supply of cooling water can effectively reduce the heat generated during the grinding process and prevent the grinding disc from being damaged by overheating. At the same time, it can also promptly remove the debris and impurities generated by grinding, thereby improving the grinding quality and efficiency. The water pumping component is used to simultaneously realize the filling of the water storage tank 31 with air and water, and there is no need to set a complex reversing mechanism or multiple moving parts for different functions to control the inflation and flushing processes respectively, making the structure of the entire device more compact and simple. When the rotating shaft 34 starts, it means that the cleaning component 30 starts working. At this time, cooling water needs to be provided in time for cooling and cleaning during the grinding process. The crankshaft 33 rotates with the start of the rotating shaft 34, driving the pumping part to start working, and pressurizing water into the water tank 31 to ensure that there is enough cooling water supplied to the grinding disc 35. When the rotating shaft 34 stops, the crankshaft 33 also stops rotating, and the pumping part stops working, and no water is added or pressurized into the water tank 31 to avoid excessive flushing, which not only ensures the normal progress of the grinding process, but also reasonably controls the use of water resources; wherein, one end of the pumping cylinder 42 is slidably connected to the inner wall of the cylinder 41, and the main body of the pumping cylinder 42 and the inner wall of the cylinder 41 have a accommodating space to allow gas to enter the accommodating cavity.

[0018] In one embodiment, reference Figure 4 as well as Figure 6 The inner wall of the enlarged portion 38 is provided with a spring 310 that matches the position and number of the water inlet holes 381. The end of the spring 310 away from the inner wall of the enlarged portion 38 is provided with a sealing plug 39. When the rotating shaft 34 is in a stationary state, the spring 310 is in a naturally extended state, and the sealing plug 39 The water inlet hole 381 is blocked under the elastic force of the spring 310. This state can prevent the cooling water in the water tank 31 from flowing into the internal cavity of the rotating shaft 34 through the water inlet hole 381 when not needed, thereby avoiding cooling water leakage. When the rotating shaft 34 rotates at high speed, the sealing plug 39 compresses the spring 310 under the action of centrifugal force, so that the water inlet hole 381 is opened. At this time, the cooling water in the water tank 31 flows into the internal cavity of the rotating shaft 34 through the water inlet hole 381 under pressure. When the speed of the rotating shaft 34 decreases or stops rotating, under the action of the restorative elastic force of the spring 310, the spring 310 drives the sealing plug 39 to re-seal the water inlet hole 381, thereby cutting off the connection between the water tank 31 and the internal cavity of the rotating shaft 34, thereby avoiding continuous leakage of cooling water when the device is not working, thereby saving water resources.

[0019] In one embodiment, reference Figure 3 , further comprising a mounting frame 20, the mounting frame 20 being provided with a moving groove 21 for the cleaning assembly 30 to move, a motor 32 being fixedly mounted on the top of the crankshaft 33, the motor 32 being fixedly connected to the top of the water tank 31 through a bracket, a mounting rod being fixedly arranged on the top of the bracket, the top of the mounting rod passing through the moving groove 21 and extending to the outside of the moving groove 21, and a nut being threadedly sleeved on one end of the mounting rod extending to the outside of the moving groove 21; Specifically, when the motor 32 is started, the motor 32 drives the crankshaft 33 to rotate. Since the crankshaft 33 is fixedly connected to the rotating shaft 34, the rotating shaft 34 rotates accordingly, thereby driving the mounting disk 36 and the grinding disk 35 to rotate. The rotating grinding disk 35 contacts the pipeline anti-corrosion layer and uses the friction force generated by its high-speed rotation to grind and remove the anti-corrosion layer. During the grinding process, if the grinding position or angle needs to be adjusted, the cleaning assembly 30 can be moved in the movable groove 21 through the mounting rod by loosening the nut, and then the nut can be tightened again to fix it, thereby meeting different grinding requirements.

[0020] In one embodiment, reference Figure 1 as well as Figure 2 , also includes two groups of mounting frames 10 respectively arranged on both sides of the mounting frame 20, the top of the mounting frame 10 is fixedly provided with a fixing frame 11, and a bidirectional lead screw 12 is rotatably connected in the fixing frame 11, and threaded sleeves 13 are threadedly sleeved on both sides of the surface of the bidirectional lead screw 12, and a clamping plate 14 is fixedly connected to the bottom of the threaded sleeve 13, and the bottom of the clamping plate 14 passes through the mounting frame 10 and extends to the outside of the mounting frame 10. When the bidirectional lead screw 12 is driven to rotate, the threaded sleeves 13 on both sides will move along the axial direction of the bidirectional lead screw 12. Due to the bidirectional thread design of the bidirectional lead screw 12, the threaded sleeves 13 on both sides will move in opposite directions. By rotating the bidirectional lead screw clockwise, the threaded sleeves 13 on both sides approach each other to achieve the clamping and limiting of the pipeline, so that when the cleaning component 30 performs operations such as grinding the anti-corrosion layer of the pipeline, the pipeline will not shake easily, thereby ensuring the stability and accuracy of the construction; when the bidirectional lead screw 12 rotates counterclockwise, the threaded sleeves 13 on both sides The two threads will move away from each other to release the pipeline, wherein the top of the threaded sleeve 13 is slidably connected to the inner wall of the fixing frame 11 .

[0021] In one embodiment, reference Figure 1 The two groups of the mounting frame 10 and the mounting frame 20 are connected in series through a fixing rod 60, and the mounting frame 10 and the mounting frame 20 are fixedly connected to the fixing rod 60 by bolts. The fixing rod 60 plays a connecting role, connecting the two groups of mounting frames 10 and the mounting frame 20 into an integral structure. When the pipeline anti-corrosion construction device is working, through the connection of the fixing rod 60, the various parts of the entire device can work better together, prevent relative displacement between the various parts, and ensure the smooth progress of the construction process. The bolts are used for fixing, so that the connection between the mounting frame 10, the mounting frame 20 and the fixing rod 60 has a certain flexibility. When installing the device, the various components can be easily assembled; and when the device needs to be disassembled, transported or maintained, the bolts can be easily unscrewed to separate the various parts for easy operation. This connection method not only ensures the stability of the device when it is working, but also takes into account the convenience during actual use.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
