[0002] In order to increase the service life of pipelines, they are generally protected against corrosion. That is, before use, a layer of anti-corrosion oil is applied to the surface of the pipeline to isolate the pipeline surface from the air and reduce the corrosion rate of the air on the pipeline. When applying anti-corrosion oil to the pipeline, it is generally done manually, that is, using an oil brush to dip the oil and then continuously apply the oil. When manually applying oil with an oil brush, it is necessary to continuously dip the oil brush into the anti-corrosion oil, and the operation back and forth will seriously reduce the speed of application and increase the complexity of the operation, resulting in low efficiency, time and effort.

[0003] In view of the above-mentioned problems, this technical solution proposes a pipeline anti-corrosion oil brushing auxiliary device. Utility Model Content

DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to 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.

[0012] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0013] like Figure 1-3The figure is a structural diagram of a pipeline anti-corrosion oil brushing auxiliary device provided by an embodiment of the utility model, comprising: a brush plate 10, bristles 11, and a brush handle 12; the bristles 11 are evenly installed on one side of the end of the brush plate 10, and the brush handle 12 is installed in the middle of the other side of the brush plate 10, that is, when in use, the brush handle 12 is held by hand to control the brush plate 10 and the bristles 11 to apply, and a handle column 13 is installed on the end of the brush handle 12 away from the brush plate 10, and a connecting valve port 14 is opened in the middle of the outer side of the handle column 13. The connecting valve port 14 is connected to the external anti-corrosion oil pipe in a snap-connected manner, and the inner end of the connecting valve port 14 is connected to an anti-corrosion oil main inlet pipe 16 arranged in the middle of the brush handle 12. The end of the anti-corrosion oil main inlet pipe 16 away from the connecting valve port 14 extends to the inside of the brush plate 10 and is connected to a diversion pipe 18 distributed along the length direction of the brush plate 10, and the diversion pipe 18 is connected to a plurality of branch pipes 2 at equal intervals toward the side of the bristles 11. 8. The end of the branch pipe 28 is connected to an oiling assembly for telescopic movement along the inside and outside of the brush plate 10. The oiling assembly is connected to a group of telescopic power assemblies arranged inside the brush plate 10. The telescopic power assembly is used to drive the oiling assembly to move along the inside of the brush plate 10 (that is, move between the brush plate 10 and the bristles 11 to oil the bristles 11, so that it can continuously oil the pipeline). A group of control buttons 15 are provided on the outer wall of the brush handle 12. At the same time, a solenoid valve 17 electrically connected to the control button 15 is provided at the input end of the solenoid valve 17, and the telescopic power assembly is electrically connected to the control button 15. When holding the brush handle 12 for use, the solenoid valve 17 and the telescopic power assembly are controlled directly by operating the control button 15, thereby controlling the start and stop of the solenoid valve 17 and the telescopic power assembly, thereby controlling the inflow and outflow of the anti-corrosion oil and the oiling of the bristles 11, realizing the auxiliary function of automatic and rapid oiling for uninterrupted application.

[0014] In an embodiment of the present utility model, when the oil filling assembly extends into the bristles 11, it sprays between the two sides of the corresponding position to ensure that the anti-corrosion oil is fully transferred to the bristles 11. The anti-corrosion oil pipe connected to the connecting valve port 14 adopts a stretchable or foldable pipe structure, so that while it transports the anti-corrosion oil toward the anti-corrosion oil main inlet pipe 16, it can be transferred synchronously with the movement of the brush handle 12, thereby reducing the resistance to the hands when manually operating the brush handle 12.

[0015] In one embodiment of the present invention, the oil filling assembly includes a telescopic sleeve 20 which is fitted and connected to the end of the branch pipe 28. The end of the branch pipe 28 placed inside the telescopic sleeve 20 is connected to a piston net 19. The piston net 19 slides along the inner wall of the telescopic sleeve 20 and the middle part of the piston net 19 is set as a mesh structure for the flow of liquid. The end of the telescopic sleeve 20 away from the branch pipe 28 is connected to the release pipe 21. The telescopic sleeve 20 and the release pipe 21 are provided with a through hole on the wall of the brush plate 10 corresponding to the release pipe 21. A circle of sealing buffer pads 23 are installed on the inner wall of the through hole. The outer side of the telescopic sleeve 20 close to the side of the branch pipe 28 is connected to the telescopic power assembly. At the same time, a side wall of the release pipe 21 facing the bristles 11 on both sides is provided. There is a side spray hole 22, which is driven by the telescopic power component to drive the telescopic sleeve 20 to move along the outside of the piston net 19, and then control the telescopic sleeve 20 and the release tube 21 to move through the through hole. When the release tube 21 extends to the inside of the bristles 11, the solenoid valve 17 is started to spray the anti-corrosion oil to be used along the anti-corrosion oil main input pipe 16, the diverter pipe 18, the branch pipe 28, the telescopic sleeve 20, the release tube 21 and then through the telescopic sleeve 20 onto the bristles 11, thereby realizing the function of automatically oiling the bristles 11. After the oiling of the bristles 11 is completed, the telescopic power component is started again to retract the release tube 21 to the inside of the brush plate 10. At this time, the solenoid valve 17 has closed the anti-corrosion oil main input pipe 16 in advance;

[0016] The telescopic power assembly includes a set of connecting rods 25 distributed parallel to the shunt pipe 18. A collar 26 is installed at the telescopic sleeve 20 corresponding to the connecting rod 25. The inner side of the collar 26 is fixedly connected to the outer side of the telescopic sleeve 20, and electric telescopic rods 24 are connected to both sides of the connecting rod 25 through connecting blocks 27. The electric telescopic rod 24 is fixed inside the brush plate 10 and is electrically connected to the control button 15. That is, under the control of the control button 15, the electric telescopic rod 24 is driven to operate, and then the electric telescopic rod 24 is used to extend and retract to drive the connecting rod 25 to move forward and backward, thereby driving the connecting rod 25 to control the movement of the telescopic sleeve 20, thereby realizing the position transfer of the release tube 21.

[0017] It should be noted that since the width of the brush plate 10 is smaller than the bristles 11, and the release tube 21 is placed inside the brush plate 10, the length of the release tube 21 will definitely be smaller than the length of the bristles 11. At this time, in order to ensure that the release tube 21 can spray a sufficient amount of oil for the bristles 11, the length of the release tube 21 is set to half of the bristles 11. After the release tube 21 injects oil to the roots of the bristles 11, the operator can hold the brush handle 12 and point the end of the bristles 11 downward. Then, under the action of gravity, the anti-corrosion oil at the roots of the bristles 11 will flow toward the bristles 11, thereby increasing the adequacy of the oil injection.

[0018] As a preferred embodiment of the present invention, in order to further increase the speed and amount of oil injection into the bristles 11, a permeable cotton layer 29 is provided at the connection between the bristles 11 and the brush plate 10. The roots of the bristles 11 are connected to the permeable cotton layer 29. A plurality of oil seepage pipes are connected to the inner side of the permeable cotton layer 29 at equal intervals along its length. The ends of the oil seepage pipes are connected to the diversion pipe 18. The diversion pipe 18 transports the anti-corrosion oil toward the branch pipe 28 while transporting it toward the oil seepage pipe, and then transfers it to the permeable cotton layer 29. By utilizing the connection between the permeable cotton layer 29 and the bristles 11, the oil gradually penetrates into the bristles 11 to inject oil into the bristles 11. The position of the seepage pipe corresponding to the connecting rod 25 is set to an arc structure to prevent distribution conflict with the connecting rod 25.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
