[0002] A water conservancy project refers to the engineering construction activities carried out for the reasonable development, utilization, protection and management of water resources. In water conservancy construction, a large number of pipelines are required for water diversion work. Before laying the water conservancy pipelines, it is necessary to polish and remove rust on the outer wall of the pipelines at the work site to remove the rust on the pipeline surface, prevent further corrosion, ensure that the pipelines are not easily affected by environmental factors during use, and thus extend the service life of the pipelines.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments 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.
[0030] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: A pipeline rust removal device for water conservancy project construction, comprising:
[0031] A bracket 1, which serves as the basic installation component of the overall rust removal device. A first motor 3 is arranged on the left side of the outside of the bracket 1. The output end of the first motor 3 is fixedly connected with a driving wheel 4. A driven wheel 6 is arranged on the left side of the outside of the bracket 1. The driving wheel 4 is connected with the driven wheel 6 through a belt 5. A reciprocating lead screw 9 is fixedly connected inside the driven wheel 6. The reciprocating lead screw 9 is rotatably connected inside the bracket 1. A moving block 10 is threadedly connected to the outside of the reciprocating lead screw 9. An upper part of the moving block 10 is fixedly connected with a mounting frame 11. A turntable 7 is fixedly connected to the outside of the driving wheel 4. The turntable 7 is rotatably connected to the outside of the bracket 1. A fixed column 8 is fixedly connected to the outside of the turntable 7. An electric push rod 12 is fixedly connected inside the mounting frame 11. The output end of the electric push rod 12 is fixedly connected with a grinding block 13. A collection box 21 is installed in the middle of the bracket 1. A handrail 20 is fixedly connected to the right side of the outside of the bracket 1. A fixed frame 22 is fixedly connected to the left side of the outside of the bracket 1. The first motor 3 is fixedly connected inside the fixed frame 22. Four rollers 2 are installed around the lower part of the bracket 1;
[0032] When rust-removing a pipeline, first, start the electric push rod 12. The electric push rod 12 drives the grinding block 13 fixed to its output end to move downward, so that the grinding block 13 contacts the outside of the pipeline. At this time, start the first motor 3. The first motor 3 drives the driving wheel 4 fixed to its output end to rotate. The rotation of the driving wheel 4 drives the driven wheel 6 to rotate through the belt 5. When the driving wheel 4 rotates, it drives the turntable 7 fixed to its outside to rotate. The rotation of the turntable 7 drives the fixed column 8 fixed to its outside to rotate. The rotation of the fixed column 8 drives the pipeline fixed to its outside to rotate. Friction is generated between the rotating pipeline and the grinding block 13, thus completing the rust-removing operation. When the driven wheel 6 rotates, it drives the reciprocating lead screw 9 fixed to its inside to rotate. The rotation of the reciprocating lead screw 9 drives the moving block 10 connected with it by external threads to move left and right reciprocally. When the moving block 10 moves, it drives the mounting bracket 11 fixed to its upper part to move synchronously. The movement of the mounting bracket 11 drives the grinding block 13 fixed to the output end of the electric push rod 12 to move synchronously, realizing the automatic rust-removing operation of the pipeline and facilitating the adjustment of the position of the grinding block 13 during rust-removing, so that the grinding block 13 can move left and right reciprocally on the outside of the pipeline. The reciprocating grinding block 13 can disperse the grinding pressure, avoid applying excessive wear force at a certain fixed position, and thus reduce excessive wear or damage to the pipeline surface. The device is facilitated to move by setting the rollers 2.
[0033] Refer to Figure 1 、 Figure 4 and Figure 5 and Figure 5 , a fixing mechanism 14 is arranged inside the fixed column 8 and is used for fixing the pipeline to be rust-removed. The fixing mechanism 14 includes a second motor 1401. The second motor 1401 is fixedly connected to the left side inside the fixed column 8. The output end of the second motor 1401 is fixedly connected with a bidirectional lead screw 1402. The bidirectional lead screw 1402 is rotatably connected inside the fixed column 8. Both sides of the outside of the bidirectional lead screw 1402 are threadedly connected with mounting blocks 1403. One ends of adjusting plates 1404 are rotatably connected to the peripheries of the two mounting blocks 1403. Connecting blocks 1405 are arranged on the peripheries of the outside of the fixed column 8. The other ends of the plurality of adjusting plates 1404 are rotatably connected to the inside of the plurality of connecting blocks 1405. Arc-shaped clamping plates 1406 are fixedly connected to the outside of the plurality of connecting blocks 1405. Telescopic rods 17 are fixedly connected to the peripheries of the outside of the fixed column 8. The tops of the plurality of telescopic rods 17 are fixedly connected to the inside of the plurality of connecting blocks 1405. Through holes 15 are formed in the peripheries of the inside of the fixed column 8. The plurality of adjusting plates 1404 are slidably connected to the inside of the plurality of through holes 15. Protective pads 16 are arranged on the outside of the plurality of arc-shaped clamping plates 1406. The materials of the plurality of protective pads 16 are rubber materials.
[0034] When fixing the pipeline that needs to be rust-removed, first, put the pipeline that needs to be rust-removed outside the four arc-shaped clamping plates 1406. At this time, start the second motor 1401, and the second motor 1401 drives the bidirectional lead screw 1402 fixed to its output end to start rotating. The rotation of the bidirectional lead screw 1402 drives the mounting blocks 1403 connected by threads on both sides of the outside to move in the opposite direction. As the two mounting blocks 1403 move relatively, the adjusting plates 1404 rotatably connected to the inner circumference of them also move relatively synchronously. The relative movement of the adjusting plates 1404 further pushes the four connecting blocks 1405 rotatably connected to the other end to move around the outside of the fixed column 8. When the four connecting blocks 1405 move, they simultaneously drive the four arc-shaped clamping plates 1406 fixed to the outside to move synchronously. During the movement of these four arc-shaped clamping plates 1406, they push the four protective pads 16 arranged outside together, so that these protective pads 16 are in close contact with the inner circumference of the pipeline, thus realizing the stable fixation of the pipeline, ensuring the stability of the pipeline during the entire rust-removing process, enabling the rust-remover to always maintain uniform contact with the pipeline surface. This uniform contact greatly reduces problems such as uneven rust-removing and residual rust in some areas that may be caused by manual fixation, thereby improving the overall quality of pipeline rust-removing. The materials of the multiple protective pads 16 are rubber materials. The rubber materials have a relatively high friction coefficient. During the fixation process, the protective pads 16 can provide greater friction when contacting the inner wall of the pipeline, preventing the pipeline from sliding or displacing during the rust-removing operation, thereby ensuring the stability of the pipeline and improving the accuracy and uniformity of the rust-removing operation.
[0035] Refer to Figure 1 and Figure 6 Figure, a collection mechanism 18 is provided at the outer rear side of the bracket 1 for collecting the dust generated during rust-removing. The collection mechanism 18 includes a collection box 1801. The collection box 1801 is fixedly connected to the outer rear side of the bracket 1. An installation shell 1803 is fixedly connected to the outside of the collection box 1801. A blower 1804 is installed inside the installation shell 1803. A drawer 1802 is slidably connected inside the collection box 1801. One end of a hose 1805 is fixedly connected to the upper part of the collection box 1801. A dust collection hood 1806 is provided at the upper part of the bracket 1. The other end of the hose 1805 is fixedly connected to the inside of the dust collection hood 1806. A filter plate 1807 is installed on the left side inside the installation shell 1803. Installation rods 19 are fixedly connected to both sides of the outside of the dust collection hood 1806. The tops of the two installation rods 19 are fixedly connected to the outside of the installation frame 11.
[0036] When rust-removing the pipeline, first start the fan 1804. The fan 1804 starts to operate, generating a strong suction force. The dust generated during the rust-removing process is quickly sucked in through the dust hood 1806. The sucked dust is then conveyed through the connected hose 1805 and finally conveyed to the inside of the collection box 1801 for centralized collection and storage. At the same time, larger impurities or debris, due to their greater weight, cannot be sucked into the inside of the dust hood 1806 and will naturally fall into the collection box 21 installed in the middle of the bracket 1 for collection. When the dust inside the collection box 1801 accumulates to a certain amount, the drawer 1802 can be taken out from the inside of the collection box 1801 and emptied or processed. This realizes the efficient classified collection of dust and debris during the pipeline rust-removing process, effectively reduces the diffusion of dust and debris in the working area, prevents them from dispersing in the air or accumulating around the equipment, and keeps the work site clean. At the same time, the classified collection of dust and debris makes the cleaning work of the work site easier, greatly reduces the cleaning workload of the operators, improves the cleanliness of the working environment. By setting the filter plate 1807, it is convenient to filter the inhaled dust and extend the service life of the fan 1804.
[0037] Working principle: When rust-removing the outside of the pipeline, first, push the handrail 20 to move the bracket 1 to the construction site through the cooperation of the rollers 2. Then, put the pipeline to be rust-removed on the outside of the four arc-shaped clamping plates 1406. At this time, start the second motor 1401. The second motor 1401 drives the bidirectional lead screw 1402 fixed to the output end to rotate. The rotation of the bidirectional lead screw 1402 drives the mounting blocks 1403 threadedly connected to both sides of the outside to move relatively. The relative movement of the two mounting blocks 1403 drives the adjusting plates 1404 rotatably connected to the four sides inside to move relatively. The relative movement of the multiple adjusting plates 1404 drives the four connecting blocks 1405 rotatably connected to the other end to move towards the outside of the fixed column 8. The movement of the four connecting blocks 1405 drives the four arc-shaped clamping plates 1406 fixed to the outside to move. The movement of the four arc-shaped clamping plates 1406 drives the four protective pads 16 arranged on the outside to move, so that the four protective pads 16 are in contact with the inner circumference of the pipeline, and the fixation of the pipeline can be completed. It realizes the convenience of fixing the pipeline to be rust-removed, without the need for operators to manually fix the pipeline, ensures the stability of the pipeline during the rust-removing process, keeps the rust-removing device in uniform contact with the pipeline surface all the time, avoids problems such as uneven rust-removing and incomplete rust-removing in some areas caused by manual fixation, and improves the quality of pipeline rust-removing. Then, when rust-removing the pipeline, start the blower 1804, suck the dust generated during rust-removing through the dust collection cover 1806, then, convey it through the hose 1805, and finally, convey the dust into the interior of the collection box 1801 through the hose 1805. The large impurities generated during the rust-removing of the pipeline will fall into the interior of the collection box 21 installed in the middle of the bracket 1. When the interior of the collection box 1801 is full, take out the drawer 1802 from the interior of the collection box 1801. It realizes that during the rust-removing of the pipeline, it is convenient to classify and collect the generated dust and debris, reduce their diffusion in the working area, keep the work site clean, reduce the cleaning workload, and improve the cleanliness of the working environment.
