Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying machines, in particular to an anti-corrosion spraying machine for anti-corrosion pipelines. Background Art
[0002] Pipelines are key infrastructure for transporting various media. They are exposed to harsh natural environments for long periods of time and are also subject to corrosion from the media they transport. In water supply systems, microorganisms, dissolved oxygen and other components in the water can corrode metal pipes. Pipeline corrosion not only causes pipe walls to become thinner, but also reduces the strength and carrying capacity of the pipes, leading to leakage accidents. Therefore, effective anti-corrosion treatment of pipelines is a key link in ensuring pipeline safety and long-term operation.
[0003] Most traditional anti-corrosion sprayers adopt a single nozzle or a few nozzle designs. When spraying larger diameter or longer pipes, this design makes it difficult to ensure uniform distribution of the paint on the pipe surface. A single nozzle can only spray at a specific position and angle, which can easily cause the local coating of the pipe to be too thick or too thin, greatly reducing the uniformity of the spraying. To address the above problems, an anti-corrosion sprayer for anti-corrosion pipes is proposed. Utility Model Content
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide an anti-corrosion spraying machine for anti-corrosion pipelines.
[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an anti-corrosion sprayer for anti-corrosion pipes, comprising a chassis, a lifting rod fixedly connected to the inner surface of the bottom end of the chassis, a pipe tray fixedly connected to the top outer wall of the lifting rod, a driving motor fixedly connected to the outside of the top end of the chassis, a liquid storage pipe movably connected to the bottom of the driving motor, a discharge pipe fixedly connected to the bottom of the liquid storage pipe, a diverter plate fixedly connected to the bottom inner wall of the diverter plate, a base fixedly connected to the top outer surface of the base, a reset spring fixedly connected to the top of the reset spring fixedly connected to the buffer plate, a connecting pipe fixedly connected to the outer surface of the diverter plate, and a spray port fixedly connected to the outer side of the connecting pipe.
[0006] As mentioned above, the diverter plate is connected to the liquid storage tube through the discharge pipe, the buffer plate is arranged in a hollow cone shape, and the top of the buffer plate is a circular setting that fits the inner wall of the discharge pipe. The inner wall diameter of the bottom of the discharge pipe is the same as the outer wall diameter of the top of the buffer plate. The buffer plate is arranged inside the diverter plate through a reset spring.
[0007] As mentioned above, the buffer tray forms a telescopic structure with the feed tube through the return spring, the feed tube and the buffer tray are both arranged at the center of the diverter tray, and the connecting tube is arranged at the bottom end of the diverter tray.
[0008] As mentioned above, the connecting pipe and the spraying ports are distributed in a ring shape on the outer surface of the diverter plate, and three groups of spraying ports are provided. The spraying ports, the connecting pipe and the diverter plate are connected through and through.
[0009] As mentioned above, the top inner wall of the chassis is fixedly connected with a fixing plate, the top inner wall of the fixing plate is movably connected with a driving gear, the driving motor passes through the chassis and is fixed to the fixing plate and the driving gear, the outer surface of one side of the driving gear is movably connected with a driven gear, the top outer surface of the driven gear is movably connected with a slide rail, the bottom end surface of the driven gear is fixedly connected with a connecting pipe, the connecting pipe is fixedly connected to the top of the liquid storage tube, and a movable groove is provided at the bottom of the fixing plate.
[0010] As mentioned above, the driven gear and the driving gear are meshed with each other, the slide rail is provided on the top inner wall of the clamping plate, and the top end of the driven gear is slidably connected to the inner wall of the slide rail.
[0011] As mentioned above, the outer surface of the connecting tube is in contact with the inner wall of the movable groove, and the liquid storage tube forms a rotating structure with the movable groove through the cooperation of the driven gear, the driving gear and the slide rail.
[0012] Compared with the existing technology, this anti-corrosion spraying machine for anti-corrosion pipelines has the following beneficial effects:
[0013] 1. The utility model can effectively buffer the impact force of the paint through the conical shape of the buffer plate and the cooperation with the discharge pipe. When the paint flows out of the discharge pipe at high speed and impacts the buffer plate, the paint will disperse and flow along the conical surface, with part of it converging to the bottom and part of it spraying around, thereby dispersing the concentrated impact force of the paint into multi-directional flow, avoiding the excessive and uneven local pressure caused by the direct impact of the paint on the diverter plate. Three groups of spray ports are distributed in a ring on the outer surface of the diverter plate. This multi-spray port design can spray the inner wall of the anti-corrosion pipeline from different angles, effectively avoiding uneven coating thickness or spray leakage due to a single spraying angle.
[0014] 2. The utility model can make circular motion around the inside of the pipeline through the liquid storage tube driven by the driving motor, which makes it convenient for the spray nozzle to continuously change the spraying angle, so that the paint can be evenly sprayed on the inner wall of the pipeline from all directions, reducing the risk of local corrosion failure due to uneven coating.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1-4As shown, the utility model provides a technical solution: an anti-corrosion sprayer for anti-corrosion pipelines, comprising a chassis 1, a lifting rod 101 is fixedly connected to the inner surface of the bottom end of the chassis 1, a pipe tray 102 is fixedly connected to the top outer wall of the lifting rod 101, a driving motor 3 is fixedly connected to the top of the chassis 1, a liquid storage pipe 2 is movably connected to the bottom of the driving motor 3, a discharge pipe 201 is fixedly connected to the bottom of the liquid storage pipe 2, a diverter plate 202 is fixedly connected to the bottom inner wall of the diverter plate 202, a base 203 is fixedly connected to the top outer surface of the base 203, a return spring 204 is fixedly connected to the top of the return spring 204 is fixedly connected to the buffer plate 205, The outer surface of the diverter disk 202 is fixedly connected to a connecting pipe 206, the outer side of the connecting pipe 206 is fixedly connected to a spray port 207, the top inner wall of the chassis 1 is fixedly connected to a fixing disk 301, the top inner wall of the fixing disk 301 is movably connected to a driving gear 302, the driving motor 3 passes through the chassis 1 and is fixedly connected to the fixing disk 301 and the driving gear 302, one side outer surface of the driving gear 302 is movably connected to a driven gear 303, the top outer surface of the driven gear 303 is movably connected to a slide rail 304, the bottom end surface of the driven gear 303 is fixedly connected to a connecting pipe 305, the connecting pipe 305 is fixedly connected to the top of the liquid storage tube 2, and a movable groove 306 is provided at the bottom of the fixing disk 301.
[0023] According to the overall structure of the device, the staff places the pipes that need anti-corrosion spraying on the pipe tray 102 in the chassis 1. There is a special interface on the outside of the liquid storage pipe 2, which is convenient for the staff to add paint to the inside. Then the drive motor 3 is started, the motor shaft starts to rotate and drives the driving gear 302 to rotate. When the driving gear 302 rotates, the driven gear 303 starts to make circular motion along the slide rail 304 under the action of meshing, and at the same time drives the connecting pipe 305 and the liquid storage pipe 2 to rotate together. The outer wall of the connecting pipe 305 fits with the inner wall of the movable groove 306 to ensure that the liquid storage pipe 2 will not deviate during the rotation process. Under the action of pressure, the paint begins to flow downward through the discharge pipe 201. When the paint flows to the bottom of the discharge pipe 201, it will impact the top of the buffer tray 205. After the paint impacts the buffer tray 205, it will disperse along the conical surface of the buffer tray 205. Part of the paint flows to the bottom of the cone under the action of gravity, and part of it is sprayed around due to the impact of the buffer tray 205 and the discharge pipe 201, thereby making the flow rate and pressure of the paint To buffer and homogenize, when the impact force of the paint is large, the buffer plate 205 will compress the return spring 204 downward to buffer the impact force of the paint. When the paint flow and pressure decrease, the return spring 204 will push the buffer plate 205 upward to return to its original position, ensuring that the paint can be better buffered and adjusted under different flow rates and pressures. The evenly mixed paint flows along the buffer plate 205 into the connecting pipe 206 outside the diverter plate 202, and finally flows to the spray port 207. The paint passes through the buffer plate 205 and is evenly sprayed out from the three groups of spray ports 207 to form multiple spraying angles to spray the inner surface of the pipeline. At the same time, as the liquid storage tube 2 rotates, the spray port 207 continuously changes the spraying angle during the rotation process. Compared with traditional fixed position or single direction movement spraying equipment, it achieves all-round coverage of the pipeline circumference, making the paint more evenly distributed on the pipeline surface. During the spraying process, the lifting rod 101 drives the pipeline tray 102 to lift the pipeline, thereby achieving uniform spraying along the entire length of the pipeline.
[0024] like Figure 1-4 As shown, the diverter disk 202 is connected to the liquid storage tube 2 through the feed pipe 201, the buffer disk 205 is set in a hollow cone shape, and the top of the buffer disk 205 is a circular setting that fits the inner wall of the feed pipe 201. The inner wall diameter of the bottom of the feed pipe 201 is the same as the outer wall diameter of the top of the buffer disk 205. The buffer disk 205 is set inside the diverter disk 202 through the reset spring 204. The buffer disk 205 forms a telescopic structure with the feed pipe 201 through the reset spring 204. The feed pipe 201 and the buffer disk 205 are both set at the center of the diverter disk 202. The connecting pipe 206 is set at the bottom end of the diverter disk 202. The connecting pipe 206 and the spray port 207 are distributed in a ring about the outer surface of the diverter disk 202, and the spray port 207 is provided in three groups. The spray port 207, the connecting pipe 206 and the diverter disk 202 are connected through.
[0025] After the paint impacts the buffer plate 205, it will disperse and flow along the conical surface of the buffer plate 205. Part of the paint flows to the bottom of the cone under the action of gravity, and part of it is sprayed around due to the impact of the buffer plate 205 and the discharge pipe 201, so that the flow rate and pressure of the paint are buffered and uniformed. When the impact force of the paint is large, the buffer plate 205 will compress the return spring 204 downward to buffer the impact force of the paint. When the paint flow and pressure decrease, the return spring 204 will push the buffer plate 205 upward to return to its original position, ensuring that the paint can be better buffered and adjusted under different flow rates and pressures. The evenly mixed paint flows along the buffer plate 205 into the connecting pipe 206 outside the diverter plate 202, and finally flows to the spray port 207. The paint passes through the buffer plate 205 and is evenly sprayed out from the three groups of spray ports 207 to form multiple spraying angles.
[0026] like Figure 1-4 As shown, there is meshing transmission between the driven gear 303 and the driving gear 302, the slide rail 304 is opened on the top inner wall of the fixing plate 301, the top of the driven gear 303 is slidably connected to the inner wall of the slide rail 304, the outer surface of the connecting tube 305 is in contact with the inner wall of the movable groove 306, and the liquid storage tube 2 forms a rotating structure with the movable groove 306 through the cooperation of the driven gear 303, the driving gear 302 and the slide rail 304.
[0027] The driving motor 3 drives the driving gear 302 to rotate. When the driving gear 302 rotates, the driven gear 303 starts to make circular motion along the slide rail 304 under the action of meshing, and at the same time drives the connecting tube 305 and the liquid storage tube 2 to rotate together. The outer wall of the connecting tube 305 fits with the inner wall of the movable groove 306 to ensure that the liquid storage tube 2 will not deviate during the rotation process. As the liquid storage tube 2 rotates, the spraying angle of the spray port 207 continuously changes during the rotation process.
[0028] Working principle: The staff places the pipes that need anti-corrosion spraying on the pipe tray 102 inside the chassis 1. The liquid storage pipe 2 has a special interface on the outside, which is convenient for the staff to add paint inside. Then the drive motor 3 is started, and the motor shaft starts to rotate and drives the driving gear 302 to rotate. When the driving gear 302 rotates, the driven gear 303 starts to make a circular motion along the slide rail 304 under the action of meshing, and at the same time drives the connecting pipe 305 and the liquid storage pipe 2 to rotate together. The outer wall of the connecting pipe 305 fits with the inner wall of the movable groove 306 to ensure that the liquid storage pipe 2 will not deviate during the rotation process;
[0029] Under the action of pressure, the paint begins to flow downward through the discharge pipe 201. When the paint flows to the bottom of the discharge pipe 201, it will impact the top of the buffer plate 205. After the paint impacts the buffer plate 205, it will disperse and flow along the conical surface of the buffer plate 205. Part of the paint flows to the bottom of the cone under the action of gravity, and part of it is sprayed around due to the impact of the buffer plate 205 and the discharge pipe 201, thereby buffering and uniforming the flow rate and pressure of the paint. When the impact force of the paint is large, the buffer plate 205 will compress the return spring 204 downward to buffer the impact force of the paint. When the paint flow and pressure decrease, the return spring 204 will push the buffer plate 205 upward to return to its original position, ensuring that the paint can be obtained under different flow rates and pressures. To achieve better buffering adjustment, the evenly mixed paint flows along the buffer plate 205 into the connecting pipe 206 outside the diverter plate 202, and finally flows to the spray port 207. The paint passes through the buffer plate 205 and is evenly sprayed out from the three groups of spray ports 207, forming multiple spraying angles to spray the inner surface of the pipeline. At the same time, as the liquid storage tube 2 rotates, the spray port 207 continuously changes the spraying angle during the rotation process. Compared with traditional fixed-position or single-direction movement spraying equipment, it achieves all-round coverage of the pipeline circumference, making the distribution of paint on the pipeline surface more uniform. During the spraying process, the lifting rod 101 drives the pipeline tray 102 to lift the pipeline, thereby achieving uniform spraying along the entire length of the pipeline.
[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
