Description

Technical Field

[0001] The invention relates to the technical field of metal grinding and polishing, in particular to a device for removing rust from the inner wall of a water conservancy water supply pipeline. Background Art

[0002] Water pipelines are infrastructure used to transport drinking water, industrial water, or other fluid media. They are widely used in urban water supply systems, agricultural irrigation, industrial production, and other fields. Selecting appropriate materials and technologies is crucial to ensuring the reliability, safety, and economy of the pipeline system.

[0003] Water supply pipes are mostly made of metal. After long-term use, the anti-rust coating on the inner wall will fall off to varying degrees. After contact with water and air, rust will appear in different positions. By taking appropriate preventive maintenance measures, not only can the negative effects of corrosion be effectively prevented, but the reliability and stability of the water supply system can also be enhanced.

[0004] However, the existing water conservancy water pipeline inner wall rust removal device has the following shortcomings:

[0005] Since the objects to be rusted are used metal pipes, and under such conditions, the pre-treated pipes are buried inside the soil layer, and the pipes are fixed with mechanical parts, the traditional rust removal method requires first removing the pipes from the soil layer, and then using adapter equipment to complete the subsequent rust removal. The rust removal work cannot be completed without disassembly, resulting in a large amount of manpower and material resources required for pipeline rust removal, which not only causes the implementation cost to be too high, but also takes a long time to rust.

[0006] Therefore, we have proposed a water conservancy water pipeline inner wall rust removal device to solve the above-mentioned problems. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides an adaptive travel component. When the device body is inserted from one end of the combined pipe, the multiple steel brushes on the plastic hollow frame deform under pressure. Due to the strong elasticity of the steel brushes themselves, they can fully fill part of the inner cavity of the combined pipe during the recovery process. The high-pressure air generated by the compressor unit is then transported through the pipe and injected into the folded airbags in sequence, causing the structure to expand and stretch, exerting thrust on the connected expansion arms. By utilizing the relevant coordination of the various components, the expansion arms are expanded in angle, allowing the connected rollers at the end to contact the inner wall of the pipe. The drive motor can provide travel power for some of the rollers, driving the connected polishing parts to slowly move within the pipe cavity. The strong friction applied by the steel brushes to the inner wall of the pipe achieves continuous rust removal. The method is mainly set according to the actual condition of the water supply pipe. When the treatment standard is met, the device body can penetrate into the interior of the combined pipe to treat the rust, eliminating the need to disassemble the combined pipes one by one. This optimizes the many disadvantages of traditional methods, reduces labor input costs, and improves rust removal efficiency.

[0022] 2. The present invention sets a processing adsorption component. The copper cover and the aluminum sieve cover can independently construct a storage space. When the equipment is running, the annular electromagnetic part is energized. Since the materials selected for the copper cover and the aluminum sieve cover are non-magnetic materials, the magnetic interference range of the annular electromagnetic part can be maximized and locked to the constructed storage space. When the fan blades are driven to rotate at high speed, the air in the storage space can be continuously extracted and an adsorption force can be formed at each hole of the aluminum sieve cover. Since the steel brushes are densely distributed, the friction strength and frequency with the pipe wall are also high, ensuring that the iron under peeling is The volume of rust is relatively small, so the adsorption force of each hole in the aluminum sieve cover is sufficient to act on the falling rust. The rust drawn into the storage space will be attracted by the magnetic force on the surface of the annular electromagnetic component again and continue to lock its surface. This method enables the equipment to have the ability to collect rust. By using airflow and electromagnetic adsorption, the collection can be completed at the moment of rust peeling, and the position can be quickly locked. The main effect is that the collected rust will not be scattered into the pipe cavity again due to the shaking of the equipment. Timely rust treatment can avoid the frequent appearance of rust residue in the discharged water after the subsequent pipeline is passed through, thereby affecting the water quality.

The end of each air intake pipe 120 and the return pipe 121 is respectively connected to the outer wall of a corresponding folding airbag 109.

[0034] The effect achieved by the entire embodiment 1 is: by presetting the above components, the use conditions of the equipment need to ensure the dryness of the inside of the pretreatment pipeline, and then before the treatment plan is implemented, the water supply at the beginning of the pipeline needs to be shut down in advance and wait for a period of time. The purpose is to ensure that the peeled rust can fall off freely and is not disturbed by water stains. The equipment body is inserted from one end of the combined pipeline. At this time, the multiple steel brushes 305 on the plastic hollow frame 304 are deformed under pressure. Since the steel brush 305 itself has strong elasticity, it can fully fill the inner cavity of the combined pipeline during the recovery process. The high-pressure air induced by the compressor unit 116 is further transported through the pipeline and injected into the folded airbag 109 in sequence, causing its structure to expand. Expansion and stretching, applying thrust to the connected expansion arm 106, and utilizing the relevant coordination of each component to complete the angular expansion of the expansion arm 106, so that the roller 114 connected at the end can contact the inner wall of the pipe, and the drive motor 115 can provide travel power for some rollers 114, driving the connected polishing parts to move slowly in the pipe cavity, and utilizing the strong friction force applied to the inner wall of the pipe by the steel brush 305 to achieve continuous shedding of rust. This method is mainly set according to the actual state of the water supply pipeline. When the treatment standard is met, the main body of the equipment can penetrate into the interior of the combined pipeline for rust treatment, and there is no need to disassemble the combined pipeline one by one, optimizing the many disadvantages brought about by the traditional method, reducing labor input costs, and improving rust removal efficiency.

[0035] Example 2, according to Figure 1 、 Figure 3-Figure 4 and Figure 6-Figure 7As shown, the processing adsorption component 300 includes a copper cover 301 and an annular electromagnetic component 302, the annular electromagnetic component 302 is embedded in the inside of the copper cover 301, the annular electromagnetic component 302 is used for rust adsorption, the outer periphery of the copper cover 301 is wrapped with an aluminum sieve cover 303, the outer wall of the aluminum sieve cover 303 is equipped with a plastic hollow frame 304, and a plurality of steel brushes 305 are evenly installed on the surface wall of the plastic hollow frame 304, the outer wall of the copper cover 301 and the inner wall of the aluminum sieve cover 303 are connected to two edges 306, and an annular sealing member 307 is installed between the outer walls of each two edges 306 through a group of bolts, a hollow cylinder sleeve 308 is inserted into the interior of the associated support plate 2, and a lifting frame 309 is installed above the hollow cylinder sleeve 308, and the top of the lifting frame 309 is connected to an electric motor 310, and the output end of the electric motor 310 is connected to a transmission rod 311, and the outer wall of the transmission rod 311 is provided with an energizing The fan blades 312 are movably placed inside the hollow sleeve 308, and the interior of the associated support plate 2 is locked with an intersection cavity 314. The lower cover 313 is encapsulated below the hollow sleeve 308. The upper and lower interfaces of the intersection cavity 314 are connected with square tubes 315, and the end of each square tube 315 is connected with a shunt joint 316. The joints of each shunt joint 316 are equidistantly connected with a group of adsorption pipes 317. One end of each group of adsorption pipes 317 passes through the copper cover 301 and the annular electromagnetic component 302. The interface of the lower cover 313 is connected with a group of second connecting pipes 318. The end of a group of second connecting pipes 318 is connected to the bottom of the intersection cavity 314. Two splicing frames 319 are installed on the top and bottom of the associated support plate 2. Four docking strips 320 are added to the interior of the copper cover 301, and each splicing frame 319 is connected to a corresponding docking strip 320.

[0036] The effect achieved by the entire embodiment 2 is as follows: by presetting the above components, the copper cover 301 and the aluminum sieve cover 303 can independently construct a storage space. When the equipment is running, the annular electromagnetic part 302 is energized. Since the materials selected for the copper cover 301 and the aluminum sieve cover 303 are non-magnetic materials, the magnetic interference range of the annular electromagnetic part 302 can be maximized and locked into the constructed storage space. When the fan blades 312 are driven to rotate at high speed, the air in the storage space can be continuously extracted, and an adsorption force can be formed at each hole of the aluminum sieve cover 303. Since the steel brushes 305 are densely distributed, the friction force with the pipe wall is increased. The number of times is also high, ensuring that the volume of the peeled rust is small, so that the adsorption force at each hole of the aluminum sieve cover 303 is sufficient to act on the falling rust, and the rust drawn into the storage space will be attracted by the magnetic force on the surface of the annular electromagnetic component 302 again, and its surface will be continuously locked. This method enables the equipment to have the ability to collect rust, and utilizes airflow and electromagnetic adsorption to complete the collection at the moment of rust peeling, and quickly lock the position. The main effect is that the collected rust will not be scattered into the pipe cavity again due to the shaking of the equipment. Timely rust treatment can avoid the frequent appearance of rust residues in the discharged water after the subsequent pipeline is passed through, thereby affecting the water quality.

[0037] The working principle of the entire equipment is as follows: before the equipment is used, the water supply of the pretreatment pipeline is shut down first, and appropriate methods are used to accelerate the removal of retained water stains in the pipe to maximize the dryness of the pipe. When the treatment conditions are met, the equipment is manually transported and inserted from the end of the pipe. The expansion arms 106 in the initial state are parallel to the inner wall of the pipe, and thus will not restrict the placement of the equipment. When the steel brush 305 on the plastic hollow frame 304 contacts the inner wall of the pipe, it will be squeezed to force the steel brush 305 structure to deform, forcing it to fully disperse, and the steel brush 305 will further enhance the contact strength with the inner wall of the pipe under the action of its own elasticity. Then the compressor unit 116 is turned on, and air enters from the end. After being pressurized by the machine body, the continuously discharged high-pressure air continues to flow into the diversion cavity 117, and then advances through the connected first connecting pipe 119 After the delivery is completed, when each two-way valve body 118 is in the open state, the air intake pipe 120 connected thereto will deliver high-pressure air to the folding airbag 109, causing its interior to gradually expand and stretch. The generated external thrust directly acts on the expansion arm 106. By utilizing the movable connection between the first crossbar 104 and the solid sleeve 105 as well as the movable joint 110 and the docking head 111, the end of the expansion arm 106 is gradually raised, and the angle continues to increase, eventually making the roller 114 fully contact with the inner wall of the pipe. Then the compressor unit 116 and the two-way valve body 118 are closed, the former stops the high-pressure delivery, and the latter prevents the backflow of high-pressure air, so that the high-pressure air is temporarily locked inside the folding airbag 109. The drive motor 115 is turned on to provide power to the connected roller 114, and the device body begins to move slowly in the channel inside the pipe.

[0038] Prior to this, the electric motor 310 is turned on and acts on the transmission rod 311, driving the fan blades 312 to rotate at high speed inside the hollow cylinder sleeve 308, which is used to extract the trapped air between the copper cover 301 and the aluminum sieve cover 303. The trapped air is transported through the adsorption pipe 317, the square tube 315 and the second connecting pipe 318. The extracted trapped air is discharged from the top of the hollow cylinder sleeve 308, and the air between the copper cover 301 and the aluminum sieve cover 303 is continuously discharged. The inside is in a negative pressure environment, utilizing the characteristic of high-pressure airflow flowing to low-pressure air. , so that each hole on the aluminum mesh cover 303 will generate an external adsorption force. At the same time, the annular electromagnetic component 302 is in an energized state. When the equipment is moving, the multiple steel brushes 305 fully rub the inner wall of the tube, and the rust attached to the inner wall will continue to fall off. The smaller rust will be captured in time by the adsorption force at the holes of the aluminum mesh cover 303 and quickly sucked between the copper cover 301 and the aluminum mesh cover 303. When it is within the range covered by the magnetic force on the surface of the annular electromagnetic component 302, the rust will be fully locked to the surface of the annular electromagnetic component 302;

[0039] After the pipeline processing is completed, take out the equipment first, use tools to twist the bolts on the annular sealing part 307 to complete the separation of the edge 306 and the annular sealing part 307, and disconnect the power supply of the annular electromagnetic part 302, then separate the aluminum sieve cover 303 from the copper cover 301, and complete the cleaning of the rust on the annular electromagnetic part 302.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. 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.
