Description

Technical Field

[0001] The present invention relates to the field of water conservancy pipeline cleaning equipment, and particularly to an automatic pipeline cleaning device for water conservancy projects. Background Technique

[0002] The pipeline system in water conservancy projects is a key component for transporting water flow, managing water resources, and realizing various water project functions. These pipeline systems can include pipelines of different types and materials, depending on their uses, environmental conditions, and the nature of the water being transported. Common steel pipes, cast iron pipes, concrete pipes, and plastic pipes, etc., can all be used in the water conveyance system. The pipelines need to have the characteristics of smooth drainage, prevention of blockage, corrosion resistance, and odor prevention, etc., to maintain environmental hygiene and prevent waterlogging.

[0003] In order to improve the service efficiency of pipelines, it is usually necessary to regularly clean the pipelines. The interior of the pipelines in water conservancy projects usually does not accumulate garbage and dirt. The main dirt comes from scale, oil stains, etc. on the inner wall of the pipelines. Conventional cleaning methods mostly involve workers holding cleaning brushes to scrub the inner wall of the pipelines, but the cleaning efficiency of the cleaning brushes is low, the cleaning effect is poor, and it is easy to have cleaning residues and breed bacteria, making it difficult to meet the cleaning requirements of the pipelines. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic pipeline cleaning device for water conservancy projects, which solves the problems that the conventional cleaning brushes have low cleaning efficiency, poor cleaning effect, and are prone to cleaning residues and breeding bacteria, making it difficult to meet the cleaning requirements of the pipelines.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An automatic pipeline cleaning device for water conservancy projects includes an automatic trolley. One end of the automatic trolley is fixedly connected with an annular mounting frame. A plurality of cleaning chambers are evenly and fixedly connected to the outer wall of the annular mounting frame. A short shaft is movably connected to the middle of each cleaning chamber. A turntable is fixedly connected to the outer end of each short shaft. A cross brush plate is fixedly connected to the outer end of each turntable. One end of the annular mounting frame away from the automatic trolley is fixedly connected with a U-shaped fixing frame. The two sides of the U-shaped fixing frame are respectively movably connected to the inner sides of both sides of a movable disc. A cleaning brush is fixedly connected to the outer diameter of the movable disc.

[0006] Preferably, driven bevel gears are fixedly installed at the inner ends of the short shafts. A DC motor is fixedly installed in the middle of the U-shaped fixing frame. The driving end main shaft of the DC motor penetrates through the inner side wall of the annular mounting frame and is fixedly connected with a driving bevel gear. The outer diameter of the driving bevel gear is meshed and connected to one side of all the driven bevel gears.

[0007] Preferably, a chuck is fixedly connected to the outer diameter of the main shaft at the driving end of the DC motor. Hemispherical protrusions are fixedly connected to one end of the chuck and the movable disk close to each other. One end of the movable disk close to the annular mounting frame is connected to one end of the annular mounting frame through a plurality of return springs.

[0008] Preferably, an annular water pipe is fixedly connected to the inner side of the annular mounting frame close to the automatic trolley. A plurality of short pipes are uniformly and fixedly connected to the inner side end of the annular water pipe. The inner side ends of the short pipes all extend into the corresponding cleaning chamber. A water pump is fixedly installed in the middle of the top end of the automatic trolley. The output end of the water pump is fixedly connected to a water delivery pipe, and the end of the water delivery pipe is communicated with the inside of the annular water pipe.

[0009] Preferably, the inner side ends of the adjacent cleaning chambers are communicated through a communicating pipe. A branch pipe is fixedly connected to the middle of the communicating pipe. The ends of the branch pipes are all fixedly connected to the outer diameter of the multi-way pipe and are communicated with the inside of the multi-way pipe.

[0010] Preferably, a sewage collection box is fixedly installed on one side of the top end of the automatic trolley close to the annular mounting frame. A sewage collection pipe is fixedly connected to one side of the multi-way pipe close to the automatic trolley. The end of the sewage collection pipe penetrates through one side of the bottom of the sewage collection box and extends into the inside of the sewage collection box.

[0011] Preferably, a negative pressure fan is fixedly installed on the top end of the sewage collection box, and an arc-shaped shield is fixedly connected to the upper side inside the sewage collection box.

[0012] Preferably, a water tank is fixedly connected to one side of the top end of the automatic trolley away from the annular mounting frame. A water suction pipe is fixedly connected to the input end of the water pump. The end of the water suction pipe penetrates through the top wall of the water tank and extends to the inner bottom of the water tank.

[0013] Working principle: Place the automatic trolley into the pipeline, start the automatic trolley to make it travel along the pipeline, then start the DC motor. The DC motor drives the main shaft to rotate, and the main shaft drives the chuck to rotate accordingly. Utilizing the toothed structure formed by the hemispherical protrusions between the chuck and the movable plate, and cooperating with the return spring, the movable plate is driven to vibrate rapidly back and forth, thereby driving the cleaning brush to vibrate accordingly. The inner wall of the pipeline is cleaned by the vibrating cleaning brush. At the same time, when the main shaft of the DC motor rotates, it also drives the driving bevel gear to rotate. Through the meshing transmission between the driving bevel gear and all driven bevel gears, all the short shafts are driven to rotate at high speed, thereby driving the turntable and the cross brush plate to rotate at high speed. At this time, turn on the water pump, and the water pump quickly pumps out the clear water in the water tank, sends it into the annular water pipe through the water delivery pipe, and then enters the cleaning chamber through the short pipe to wash the inner wall of the pipeline. Cooperating with the cross brush plate rotating at high speed, the water flow is slapped into fine water droplets, mixed with air to form a high-speed water-vapor fluid, bringing a powerful flushing force to the inner wall of the pipeline. The negative pressure fan at the top of the sewage collection tank generates a powerful suction force, instantly pumping the inside of the sewage collection tank to a vacuum state. The huge negative pressure sucks the dirt brushed down by the cross brush plate into the sewage collection tank through the connecting pipe, multi-way pipe and sewage collection pipe. The dirt falls to the bottom of the sewage collection tank under the influence of gravity after contacting the arc-shaped cover. By controlling the forward movement of the automatic trolley, the automatic cleaning of the inner wall of the pipeline is completed.

[0014] The present invention provides a pipeline automatic cleaning device for water conservancy projects. It has the following beneficial effects:

[0015] In the present invention, the clear water is pumped into the cleaning chamber by the water pump. Cooperating with the cross brush plate rotating at high speed, the water flow is slapped into fine water droplets, mixed with air to form a high-speed water-vapor fluid, bringing a powerful flushing force to the inner wall of the pipeline, and completing the cleaning work of the inner wall of the pipeline. Cooperating with the cleaning brush that vibrates continuously before cleaning to brush the inner wall of the pipeline, the cleaning work of the inner wall of the pipeline can be completed efficiently and with high quality. Compared with traditional brushes, it is hydrophobic and oleophobic, does not stick to stains, does not breed bacteria, is simple and convenient to operate, and has stronger practicability.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment:

[0023] Please refer to the attached Figure 1 - attached Figure 4 , the embodiment of the present invention provides an automatic pipeline cleaning device for water conservancy projects. As Figure 1 shown, it includes an automatic trolley 1, an electric trolley that can perform automatic driving, which belongs to the prior art and will not be described in detail here. One end of the automatic trolley 1 is fixedly connected to a ring mounting bracket 2, which is ring-shaped with both sides closed. A number of cleaning chambers 3 are evenly and fixedly connected to the outer wall of the ring mounting bracket 2. A short shaft 4 is movably connected to the middle of each cleaning chamber 3. The middle of the short shaft 4 is connected to the inner side wall of the cleaning chamber 3 through a bearing seat. The outer ends of the short shafts 4 are all fixedly connected to turntables 6, and the outer ends of the turntables 6 are all fixedly connected to cross brush plates 7, which are cross-shaped. One end of the ring mounting bracket 2 away from the automatic trolley 1 is fixedly connected to a U-shaped fixing bracket 8, which is U-shaped. On the one hand, it is convenient to install and fix the DC motor 9, and on the other hand, it can guide and limit the operation of the movable disk 11. The two sides of the U-shaped fixing bracket 8 are respectively movably connected to the inner sides of the two sides of the movable disk 11. A cleaning brush 12 is fixedly connected to the outer diameter of the movable disk 11, which is used to complete the main cleaning structure of the inner wall of the pipeline.

[0024] In this embodiment, driven bevel gears 5 are fixedly installed at the inner ends of the short shafts 4. A DC motor 9 is fixedly installed in the middle of the U-shaped fixing frame 8. The driving end of the DC motor 9 can be connected to a speed reducer. The main shaft of the driving end of the DC motor 9 penetrates through the inner side wall of the annular mounting frame 2 and is fixedly connected to a driving bevel gear 10. The outer diameter of the driving bevel gear 10 meshes with one side of all the driven bevel gears 5. By driving the driving bevel gear 10 to rotate through the DC motor 9, all the driven bevel gears 5 and the short shafts 4 can be driven to rotate, thereby driving all the turntables 6 and the cross brush plates 7 to rotate at high speed.

[0025] Furthermore, a chuck 13 is fixedly connected to the outer diameter of the main shaft of the driving end of the DC motor 9. A plurality of hemispherical protrusions 14 are fixedly connected to one end of the chuck 13 and the movable disk 11 close to each other. The hemispherical protrusions 14 on both sides are staggered from each other to form an intermeshing structure. One end of the movable disk 11 close to the annular mounting frame 2 is connected to one end of the annular mounting frame 2 through a plurality of return springs 15. When the hemispherical protrusions 14 on the chuck 13 rotate, they will squeeze the hemispherical protrusions 14 on the movable disk 11, forcing them to move. With the action of the return springs 15, rapid reciprocating vibration of the movable disk 11 is realized.

[0026] Specifically, by driving the main shaft to rotate through the DC motor 9, the main shaft will drive the chuck 13 to rotate accordingly. By using the intermeshing structure formed by the hemispherical protrusions 14 between the chuck 13 and the movable disk 11 and cooperating with the return springs 15, the movable disk 11 is driven to vibrate rapidly back and forth, thereby driving the cleaning brush 12 to vibrate accordingly, and the inner wall of the pipeline is cleaned by the vibrating cleaning brush 12.

[0027] Furthermore, an annular water pipe 16 is fixedly connected to the inner side of the annular mounting frame 2 close to the automatic trolley 1. It is annular in shape. A plurality of short pipes 17 are evenly and fixedly connected to the inner side end of the annular water pipe 16. The inner side ends of the short pipes 17 all extend into the corresponding cleaning chambers 3. Clear water is conveyed into the cleaning chambers 3 through the short pipes 17. A water pump 19 is fixedly installed in the middle of the top end of the automatic trolley 1. The output end of the water pump 19 is fixedly connected to a water delivery pipe 18 for conveying clear water. The end of the water delivery pipe 18 is connected to the inside of the annular water pipe 16. A water tank 27 is fixedly connected to the side of the top end of the automatic trolley 1 far from the annular mounting frame 2. The input end of the water pump 19 is fixedly connected to a water suction pipe 28. The end of the water suction pipe 28 penetrates through the top wall of the water tank 27 and extends to the inner bottom of the water tank 27. The clear water in the water tank 27 is pumped out through the water pump 19 and then sent into the cleaning chambers 3 through the water delivery pipe 18, the annular water pipe 16 and the short pipes 17.

[0028] Specifically, when the DC motor 9 drives the main shaft to rotate, it will also drive the driving bevel gear 10 to rotate. Through the meshing transmission between the driving bevel gear 10 and all the driven bevel gears 5, all the short shafts 4 are driven to rotate at high speed, thereby driving the turntable 6 and the cross brush plate 7 to rotate at high speed. At this time, the water pump 19 is turned on, and the water pump 19 quickly pumps out the clear water in the water tank 27, sends it into the annular water pipe 16 through the water supply pipe 18, and then enters the cleaning chamber 3 through the short pipe 17 to wash the inner wall of the pipe. Cooperating with the cross brush plate 7 rotating at high speed, the water flow is dispersed into fine water droplets, mixed with air to form a high-speed water-vapor fluid, bringing a strong washing force to the inner wall of the pipe and completing the high-quality cleaning work of the inner wall of the pipe.

[0029] Furthermore, the inner ends of the connected cleaning chambers 3 are connected through a communicating pipe 20. A branch pipe 21 is fixedly connected to the middle of the communicating pipe 20. The ends of the branch pipes 21 are fixedly connected to the outer diameter of the multi-way pipe 22 and are connected to the inside of the multi-way pipe 22. On the side of the top of the automatic trolley 1 close to the annular mounting frame 2, a sewage collection tank 24 is fixedly installed for collecting sewage and dirt generated during cleaning. A sewage collection pipe 23 is fixedly connected to the side of the multi-way pipe 22 close to the automatic trolley 1. The end of the sewage collection pipe 23 penetrates through the bottom side of the sewage collection tank 24 and extends into the inside of the sewage collection tank 24. The part of the sewage collection pipe 23 located inside the sewage collection tank 24 extends upward to facilitate the dirt to fall after being pumped into the sewage collection tank 24. A negative pressure fan 25 is fixedly installed at the top of the sewage collection tank 24. The negative pressure fan 25 can quickly pump the inside of the sewage collection tank 24 to a vacuum state, so that a huge negative pressure sucks the dirt into the inside. An arc-shaped baffle 26 is fixedly connected to the upper side inside the sewage collection tank 24 to block the dirt and facilitate collection.

[0030] Specifically, during the cleaning process, a strong suction force is generated by the negative pressure fan 25 at the top of the sewage collection tank 24, instantly pumping the inside of the sewage collection tank 24 to a vacuum state. The huge negative pressure sucks the dirt brushed off by the cross brush plate 7 into the sewage collection tank 24 through the communicating pipe 20, the multi-way pipe 22 and the sewage collection pipe 23. After the dirt contacts the arc-shaped baffle 26, it falls to the bottom of the sewage collection tank 24 under the influence of gravity.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
