Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a high-efficiency sand removal water conservancy pipeline cleaning device. Background Technology

[0002] Water conservancy pipelines refer to pipeline systems used to transport water resources. During the drainage process, some impurities and silt in the water flow will adhere to the inner wall of the pipeline. In order to ensure the normal drainage function of the pipeline, it is usually necessary to clean the inside of the pipeline regularly.

[0003] A search revealed that the Chinese patent "A Water Pipeline Cleaning Device" (authorization announcement number CN221657403U) uses a controller to turn on the motor and water pump. The motor drives the first telescopic cylinder, water supply tank, delivery pipe, and four brushes on its surface to rotate, facilitating the removal of impurities from the inner wall. Simultaneously, the water pump delivers clean water from the water supply tank to sixteen telescopic pipes through the delivery pipes, and then to four connecting cylinders. Finally, the water is sprayed onto the inner wall of the pipe through nozzles on one side of the four connecting cylinders. The combined use of four brushes and several nozzles effectively and completely cleans even stubborn stains from the inner wall of the pipe, resulting in a better cleaning effect.

[0004] Although the aforementioned application can clean the inner wall of the pipe, the brush bristles are somewhat soft. During the cleaning process, when the brush cleans the stubborn mud and impurities adhering to the inner wall of the pipe, the bristles will deform, thus affecting the cleaning effect on the inner wall of the pipe.

[0005] Therefore, a high-efficiency sand removal water conservancy pipeline cleaning device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an efficient sand-removing water conservancy pipeline cleaning device to solve the above-mentioned problems. It improves the problem that when the brush bristles are soft, they deform during the cleaning process, which affects the cleaning effect on the inner wall of the pipeline.

[0007] This utility model achieves the above objectives through the following technical solution: a high-efficiency sand removal type water conservancy pipeline cleaning device, comprising: a movable limiting cylinder, wherein a rotating rod is rotatably connected to the inner wall of the movable limiting cylinder, and one end of the rotating rod passes through the movable limiting cylinder and is provided with a cleaning mechanism;

[0008] The cleaning mechanism includes a mounting cylinder fixedly connected to the other end of a rotating rod. Four first electric push rods arranged in a ring are fixedly connected to the surface of the mounting cylinder. A mounting plate is fixedly connected to the other end of each first electric push rod. A first cleaning plate is fixedly connected to the end of the mounting plate away from the first electric push rod. A reciprocating screw is rotatably connected to the inner wall of the mounting plate. A movable plate is provided on the surface of the reciprocating screw. The end of the movable plate penetrates into the interior of the first cleaning plate and is fixedly connected to a second cleaning plate. One side of the second cleaning plate extends out of the first cleaning plate.

[0009] Preferably, the cleaning mechanism further includes a water inlet pipe embedded in the inner wall of the rotating rod. The other end of the water inlet pipe extends into the interior of the mounting cylinder and is connected to four connecting pipes. The other end of each connecting pipe extends out of the mounting cylinder. The positions of the four connecting pipes correspond one-to-one with the positions of the four first cleaning plates. A water wheel is rotatably connected to the inner wall of each connecting pipe. One end of the water wheel's rotating shaft extends into the interior of the corresponding mounting plate and is fixedly connected to one end of a reciprocating screw. This facilitates the moving plate driving the second cleaning plate to continuously reciprocate, colliding with the mud and impurities on the inner wall of the pipe, breaking down stubborn impurities, thereby allowing the second and first cleaning plates to better scrape away stubborn mud and impurities from the pipe.

[0010] Preferably, two round rods are fixedly connected to one side of the mounting plate, and brushes are slidably connected to the surface of the round rods. A fixing rod is fixedly connected to the other side of the second cleaning plate, and the other end of the fixing rod passes through the first cleaning plate and is fixedly connected to one side of the brushes. This facilitates the re-cleaning of the pipe inner wall after the first cleaning plate has cleaned it, making the cleaning more thorough. At the same time, the reciprocating movement of the brushes enhances the cleaning effect.

[0011] Preferably, the surface of the connecting pipe is connected to a plurality of nozzles, which are arranged at an angle. This helps to enhance the cleaning effect on the inner wall of the pipe.

[0012] Preferably, a motor is installed inside the movable limiting cylinder, and bevel gears are fixedly connected to both the surface of the rotating rod and the output shaft of the motor, with the two bevel gears meshing together. This facilitates a stable connection between the water inlet pipe and the rotating rod while ensuring the normal operation of the cleaning device.

[0013] Preferably, one side of the second cleaning plate has a V-shaped overall shape. This enhances the effect of the second cleaning plate repeatedly colliding with the stubborn mud and sand on the inner wall of the pipe.

[0014] Preferably, the end of the first cleaning plate furthest from the mounting plate is inclined. This ensures the cleaning effect of the first cleaning plate while reducing the friction between the first cleaning plate and the inner wall of the pipe during the cleaning process.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this application, the cleaning mechanism is driven to rotate by a drive rod, which helps the installation cylinder to drive the second cleaning plate to initially scrape and clean the mud and impurities on the inner wall of the pipe. The first cleaning plate rotates against the inner wall of the pipe to perform secondary scraping and cleaning, which reduces the cleaning pressure of the first and second cleaning plates while enhancing the cleaning effect on the inner wall of the pipe. During the cleaning process, under the action of the water flow, water wheel and reciprocating screw inside the connecting pipe, the moving plate drives the second cleaning plate to move back and forth continuously during the cleaning process, colliding with the mud and impurities on the inner wall of the pipe, breaking down stubborn impurities. This allows the second and first cleaning plates to better scrape away stubborn mud and impurities in the pipe, which is conducive to a more thorough cleaning of the inner wall of the pipe.

[0017] 2. It is beneficial to clean the smaller gaps in the inner wall of the pipe after the first cleaning plate has cleaned it, making the cleaning more thorough. At the same time, the cleaning effect of the brush is enhanced by the reciprocating movement of the brush. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-5 As shown, a high-efficiency sand removal type water conservancy pipeline cleaning device includes: a movable limiting cylinder 1, a rotating rod 2 rotatably connected to the inner wall of the movable limiting cylinder 1, and one end of the rotating rod 2 passing through the movable limiting cylinder 1 and equipped with a cleaning mechanism 3;

[0026] The cleaning mechanism 3 includes a mounting cylinder 31 fixedly connected to the other end of the rotating rod 2. Four first electric push rods 32, arranged in a ring, are fixedly connected to the surface of the mounting cylinder 31. A mounting plate 33 is fixedly connected to the other end of each first electric push rod 32. A first cleaning plate 34 is fixedly connected to the end of the mounting plate 33 away from the first electric push rods 32. A reciprocating screw 35 is rotatably connected to the inner wall of the mounting plate 33. A movable plate 36 is provided on the surface of the reciprocating screw 35. The end of the movable plate 36 extends into the interior of the first cleaning plate 34 and is fixedly connected to a second cleaning plate 37. One side of the second cleaning plate 37 extends out of the first cleaning plate 34. The movable limiting cylinder 1 includes a cylinder and four second electric push rods mounted on the surface of the cylinder. A movable wheel is mounted on the other end of each second electric push rod. When cleaning the inner wall of a pipe using this device, the device is placed inside the pipe, and the controller simultaneously activates the second electric push rods to push the movable wheel against the inner wall of the pipe, thus limiting the cleaning mechanism 3.

[0027] After completing the above steps, the controller simultaneously activates the four first electric push rods 32, causing the first electric push rods 32 to push the end of the first cleaning plate 34 to press against the inner wall of the pipe. At this time, the second cleaning plate 37 does not contact the inner wall of the pipe and the gap between it and the inner wall of the pipe is small. The cleaning mechanism 3 is driven to rotate by the drive rod 2.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, the cleaning mechanism 3 also includes a water inlet pipe 38 embedded in the inner wall of the rotating rod 2. The other end of the water inlet pipe 38 extends into the interior of the mounting cylinder 31 and is connected to four connecting pipes 39. The other end of each connecting pipe 39 extends out of the mounting cylinder 31. The positions of the four connecting pipes 39 correspond one-to-one with the positions of the four first cleaning plates 34. A water wheel 310 is rotatably connected to the inner wall of each connecting pipe 39. One end of the rotating shaft of the water wheel 310 extends into the interior of the corresponding mounting plate 33 and is fixedly connected to one end of the reciprocating screw 35. The middle section of the connecting pipe 39 is corrugated to ensure that the connecting pipe 39 can be stretched normally. The water inlet pipe 38 can be connected to an external aqueous solution delivery pipe via a sealed bearing.

[0029] During the cleaning process, the aqueous solution enters the connecting pipe 39 through the inlet pipe 38. The water wheel 310 is set at the eccentric position of the connecting pipe 39. When the water flows through the connecting pipe 39, it drives the water wheel 310 to rotate, thereby driving the reciprocating screw 35 to rotate. The reciprocating screw 35 is in the form of two threaded grooves with the same pitch and opposite directions of rotation, with the two ends connected by a transition curve. Through the rotation of the reciprocating screw 35, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. Therefore, when the reciprocating screw 35 rotates, it will drive the second cleaning plate 37 to move back and forth during the cleaning process through the moving plate 36, thereby continuously colliding with the more stubborn sand and gravel.

[0030] like Figure 4 As shown, two round rods 311 are fixedly connected to one side of the mounting plate 33, and a brush 312 is slidably connected to the surface of the round rods 311. A fixing rod 313 is fixedly connected to the other side of the second cleaning plate 37, and the other end of the fixing rod 313 passes through the first cleaning plate 34 and is fixedly connected to one side of the brush 312.

[0031] While the first cleaning plate 34 is in contact with the inner wall of the pipe, the bristles of the brush 312 are in contact with the inner wall of the pipe. When the second cleaning plate 37 moves back and forth, the brush 312 will move back and forth synchronously through the fixing rod 313.

[0032] like Figure 3 As shown, the surface of the connecting pipe 39 is connected to a plurality of nozzles 314, which are arranged at an angle.

[0033] The water flow in the connecting pipe 39 will be sprayed out through multiple nozzles 314 to rinse the inner wall of the pipe. It should be noted that after the first cleaning plate 34, the second cleaning plate 37, and the brush 312 clean the inner wall of the pipe, the nozzles 314 at the corresponding positions will rinse the cleaned inner wall.

[0034] like Figure 2As shown, a motor 21 is installed inside the movable limiting cylinder 1, and bevel gears 22 are fixedly connected to the surface of the rotating rod 2 and the output shaft of the motor 21. The two bevel gears 22 are meshed together.

[0035] When cleaning the inner wall of the pipe using the cleaning mechanism 3, the motor 21 is started by the controller. The output shaft of the motor 21 will drive the rotating rod 2 to rotate through two bevel gears 22. At this time, the rotating rod 2 will drive the cleaning mechanism 3 to rotate.

[0036] like Figure 5 As shown, the overall shape of one side of the second cleaning plate 37 is "V". During the cleaning process, the V-shaped side of the second cleaning plate 37 continuously collides with the mud and impurities on the inner wall of the pipe, and the inclined surface helps the impurities cleaned by the first cleaning plate 34 to fall off more effectively.

[0037] like Figure 5 As shown, the end of the first cleaning plate 34 furthest from the mounting plate 33 is inclined. During the rotation cleaning process, the highest point of the inclined surface of the first cleaning plate 34 contacts the inner wall of the pipe.

[0038] In use, the device is placed inside the pipe and the moving limiting cylinder 1 is driven to limit the cleaning mechanism 3. The inlet pipe 38 is then connected to the external aqueous solution delivery pipe via a sealed bearing. After this operation, the controller simultaneously activates four first electric push rods 32 to push the ends of the first cleaning plate 34 against the inner wall of the pipe. Simultaneously, the bristles of the brush 312 contact the inner wall of the pipe. The controller also activates the motor 21, which drives the rotating rod 2 through two bevel gears 22. This rotating rod 2 drives the cleaning mechanism 3 to rotate synchronously, causing the mounting cylinder 31 to drive the second cleaning plate 37 to perform initial scraping and cleaning of the mud and impurities on the inner wall of the pipe. The first cleaning plate 34 rotates against the inner wall of the pipe for secondary scraping and cleaning. The brush 312 then... The first cleaning plate 34 cleans the inner wall of the pipe again. At the same time, the external aqueous solution enters the connecting pipe 39 through the water inlet pipe 38 and is sprayed out through multiple nozzles 314 to rinse the inner wall of the pipe. When the water flows through the connecting pipe 39, it drives the water wheel 310 to rotate, which in turn drives the reciprocating screw 35 to rotate. When the reciprocating screw 35 rotates, it drives the second cleaning plate 37 to move back and forth during the cleaning process through the moving plate 36. This causes the V-shaped side of the second cleaning plate 37 to continuously collide with the mud and impurities on the inner wall of the pipe during the cleaning process, breaking up stubborn impurities. At the same time, under the action of the fixed rod 313, the second cleaning plate 37 drives the brush 312 to move back and forth synchronously to clean the inner wall of the pipe.

[0039] It should be noted that the motor 21, the first electric push rod 32, and the second electric push rod mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the motor 21, the first electric push rod 32, and the second electric push rod can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
