Description

Technical Field

[0001] This invention relates to the field of reservoir construction, specifically to a device for cleaning the outer surface of pipelines used in reservoir construction. Background Technology

[0002] During the construction of reservoir projects, various water conveyance and drainage pipelines are important supporting infrastructure. The outer surface of the pipelines is exposed to the soil, sand, gravel and sewage environment of the construction site for a long time, which easily causes a large amount of dirt, rust, debris and other dirt to adhere to it. If it is not cleaned in time, it will not only affect the subsequent installation, welding and anti-corrosion treatment of the pipeline, but also accelerate the corrosion of the outer wall after the pipeline is put into use, reducing the service life and structural stability of the pipeline.

[0003] However, in practical applications, the existing sewage removal devices for reservoir construction pipelines have fixed positions for their cleaning components, making it difficult to adapt to pipelines of different diameters and resulting in poor versatility. Some adjustable sewage removal devices have low adjustment precision, and the various cleaning components cannot synchronously fit the outer wall of the pipeline, easily leading to cleaning dead zones and poor cleaning effect. Summary of the Invention

The synchronous drive unit includes an internal gear ring that is rotatably connected to the annular mounting groove wall. The annular mounting groove is also rotatably connected to a rotating shaft that corresponds to each rack. A second gear that meshes with the rack and the internal gear ring is fixed on the rotating shaft. A first motor is fixedly connected to the outside of the rotating ring.

A guide rod parallel to the double-threaded rod is fixedly installed in the second mounting slot. A second sliding sleeve is threaded onto both the positive and negative thread sections of the double-threaded rod, and both second sliding sleeves are slidably connected to the guide rod. A transmission rod is hinged to the bottom of each of the two second sliding sleeves, and the other end of each transmission rod is hinged to the top of the lifting ring.

[0013] Compared with the prior art, the present invention provides a device for cleaning the outer surface of pipelines used in reservoir construction, which has the following advantages: 1. This invention uses a synchronous drive unit to drive multiple sets of racks to move synchronously along the radial direction of a rotating ring.

[0017] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0018] Please refer to Figures 1 to 4As shown, a device for cleaning the outer surface of a reservoir construction pipeline includes a base 1. Two symmetrically distributed vertical rods 2 are fixedly connected to the top of the base 1. A top plate 3 is fixedly connected to the top of the two vertical rods 2. A lifting ring 4 is positioned between the two vertical rods 2 and located below the top plate 3. First sliding sleeves 5 are fixedly connected to both sides of the lifting ring 4, and the two first sliding sleeves 5 are slidably connected to the two vertical rods 2 respectively. A coaxially arranged rotating ring 6 is rotatably connected to one end of the lifting ring 4. A reciprocating rotation drive unit 7 is provided between the lifting ring 4 and the rotating ring 6. Several ring-shaped components are slidably connected radially along the rotating ring 6. The array of racks 9 and rotating rings 6 have annular mounting grooves 8 on the side of their rings away from the lifting rings 4. Each rack 9 passes through the annular mounting groove 8, and both ends of the rack 9 protrude from the annular mounting groove 8. A synchronous drive unit 10 connected to each rack 9 is installed in the annular mounting groove 8. A cleaning component 11 is installed at one end of each rack 9 located in the inner ring of the rotating ring 6. A limit plate is fixedly connected to the end of the rack 9 away from the cleaning component 11. A lifting mechanism 12 connected to the lifting rings 4 is installed on the top plate 3. Each vertical rod 2 is equipped with a scale line 13 that matches the outer diameter of the pipe.

[0019] Those skilled in the art will understand that the lifting ring 4 achieves vertical displacement adjustment through the sliding engagement of the first sliding sleeves 5 on both sides with the vertical rod 2. The rotating ring 6, which is rotatably connected to one end of the lifting ring 4, can perform reciprocating rotational motion through the reciprocating rotational drive unit 7. Several ring arrays of racks 9, which slide radially on the rotating ring 6, are inserted into the annular mounting groove 8. The synchronous drive unit 10 in the annular mounting groove 8 can drive all racks 9 to move radially synchronously. The cleaning component 11 at the inner ring end of the rack 9 moves with the rack 9 to achieve contact adjustment with the outer wall of the pipe. The limiting plate at the other end of the rack 9 can prevent the rack 9 from slipping. The lifting mechanism 12 on the top plate 3 provides vertical driving force for the lifting ring 4. The pipe diameter scale line 13 on the vertical rod 2 can achieve precise positioning of the radial movement of the rack 9. This structure realizes the basic functions of precise position adjustment and rotational cleaning of the cleaning component 11, laying a structural foundation for subsequent adaptation to pipes of different diameters and all-round cleaning. At the same time, the design of the limiting plate and the scale line 13 improves the stability of the device operation and the accuracy of adjustment.

[0020] Furthermore, the top of the base 1 is fixedly connected to a support frame 14 symmetrically distributed on both sides of the lifting ring 4. The top of the support frame 14 is provided with a V-shaped placement groove 15. The two inclined surfaces of the V-shaped placement groove 15 are provided with a first mounting groove 16. Several sliding rollers 17 are rotatably connected in the first mounting groove 16. The top of the sliding roller 17 protrudes from the inclined surface of the V-shaped placement groove 15, so that the pipe and the sliding roller 17 roll in contact.

[0021] Those skilled in the art will understand that the pipe is supported by the symmetrically distributed support frames 14 on the top of the base 1. The V-shaped placement groove 15 on the top of the support frame 14 can be adapted to the placement and positioning of pipes of different diameters. The top of the sliding roller 17 rotatably connected in the first mounting groove 16 on both sides of the V-shaped placement groove 15 protrudes from the inclined surface of the V-shaped placement groove 15, so that the pipe and the sliding roller 17 form a rolling contact. This structure can not only provide stable support for the pipe and prevent the pipe from shifting during the cleaning process, but also enable the pipe to move easily through the rolling of the sliding roller 17 without the need for heavy manual handling, which greatly reduces the labor cost of pipe positioning and displacement adjustment. At the same time, the design of the V-shaped placement groove 15 further improves the adaptability of the device to pipes of different diameters, and works in conjunction with the structure of Embodiment 1 to make the preliminary preparation for pipe cleaning more convenient.

[0022] Furthermore, the reciprocating rotary drive unit 7 includes a forward and reverse motor 701 fixedly connected to the inner ring of the lifting ring 4. The output end of the forward and reverse motor 701 is fixedly connected to a first gear 702, and the end of the rotating ring 6 near the lifting ring 4 is fixedly connected to an external gear ring 703 that meshes with the first gear 702.

[0023] Those skilled in the art will understand that the forward and reverse motor 701 outputs power, and the first gear 702 at its output end meshes with the outer gear ring 703 at one end of the rotating ring 6. The forward and reverse rotation of the forward and reverse motor 701 can drive the first gear 702 to rotate, and then drive the rotating ring 6 to reciprocate through the meshing outer gear ring 703. This drive structure has stable transmission and high power transmission efficiency. The precise reciprocating rotation of the rotating ring 6 is achieved through gear meshing, which drives the cleaning component 11 to perform circumferential reciprocating cleaning along the outer wall of the pipe. This effectively avoids the dead angle problem caused by cleaning in one direction and improves the comprehensiveness of cleaning. At the same time, the forward and reverse motor 701 has strong controllability and can adjust the rotation speed and angle according to the degree of dirt in the pipe, making the cleaning operation more flexible.

[0024] Furthermore, the synchronous drive unit 10 includes an internal gear ring 1001 rotatably connected to the inner wall of the annular mounting groove 8. The inner wall of the annular mounting groove 8 is also rotatably connected to a rotating shaft 1002 corresponding to each rack 9. Each rotating shaft 1002 is fixedly connected to a second gear 1003 that meshes with the corresponding rack 9. Each second gear 1003 meshes with the internal gear ring 1001. A first motor 1004 is fixedly connected to the outer side of the rotating ring 6, and the output end of the first motor 1004 is fixedly connected to one end of one of the rotating shafts 1002. A detachable end plate that closes the annular mounting groove 8 is mounted on the side of the rotating ring 6 away from the lifting ring 4, and the first motor 1004 is fixedly mounted on the end plate.

[0025] As will be understood by those skilled in the art, the first motor 1004 drives one of the rotating shafts 1002 to rotate, which in turn drives the corresponding second gear 1003 to rotate. This, in turn, drives all the second gears 1003 to rotate synchronously through the linkage of the internal gear ring 1001. Ultimately, all the racks 9 move synchronously along the radial direction of the rotating ring 6. This synchronous drive structure ensures the synchronicity and consistency of the movement of each rack 9 through the meshing linkage of the gears and the internal gear ring 1001. This allows all the cleaning components 11 to fit evenly against the outer wall of pipes of different diameters, avoiding the problem of incomplete cleaning caused by uneven fitting of the cleaning components 11. At the same time, the single-motor drive simplifies the structure, reduces the failure rate and maintenance cost of the device, and improves the stability of the device operation.

[0026] Furthermore, the cleaning component 11 includes a mounting frame 1101 fixedly connected to one end of the rack 9, a cleaning roller brush 1102 rotatably connected inside the mounting frame 1101, and a second motor 1103 fixedly connected to the outside of the mounting frame 1101. The output end of the second motor 1103 is fixedly connected to one end of the roller shaft of the cleaning roller brush 1102.

[0027] Those skilled in the art will understand that the mounting frame 1101 provides mounting support for the cleaning roller brush 1102, and the second motor 1103 outputs power and is fixedly connected to the roller shaft of the cleaning roller brush 1102, which can drive the cleaning roller brush 1102 to rotate at high speed. This cleaning component 11 forms active cleaning by driving the roller brush to rotate through the motor. Compared with the traditional passive cleaning method, it has a greater cleaning force and higher efficiency, and can effectively remove stubborn dirt such as mud and rust from the outer wall of the pipe. The independent second motor 1103 can also adjust the roller brush speed according to the dirt condition to adapt to different cleaning needs.

[0028] Furthermore, the lifting mechanism 12 includes a second mounting groove 1201 opened on the top plate 3. A double-threaded rod 1202 is rotatably connected in the second mounting groove 1201. A third motor 1203 is fixedly connected to the side wall of the top plate 3. The output end of the third motor 1203 is fixedly connected to one end of the double-threaded rod 1202. A guide rod 1204 parallel to the double-threaded rod 1202 is also fixedly connected in the second mounting groove 1201. A second sliding sleeve 1205 is threadedly connected to both the positive and negative thread sections of the double-threaded rod 1202. Both second sliding sleeves 1205 are slidably connected to the guide rod 1204. A transmission rod 1206 is hinged to the bottom of both second sliding sleeves 1205. The other end of both transmission rods 1206 is hinged to the top of the lifting ring 4.

[0029] As will be understood by those skilled in the art, the double-ended threaded rod 1202 is driven to rotate by the third motor 1203, and the guide rod 1204 in the second mounting groove 1201 guides the two second sliding sleeves 1205. The positive and negative threaded sections of the double-ended threaded rod 1202 drive the two second sliding sleeves 1205 to slide towards or away from each other along the guide rod 1204. Then, through the transmission rod 1206 hinged at the bottom, the lifting ring 4 is pushed or pulled to move vertically up and down along the vertical rod 2. This lifting structure achieves precise vertical displacement adjustment of the lifting ring 4 through screw transmission. It has high transmission accuracy and stable operation. It can flexibly adjust the vertical position of the cleaning component 11 according to the placement height of the pipeline and the cleaning requirements, so that the cleaning component 11 can be accurately aligned with the part of the pipeline to be cleaned. At the same time, the guiding effect of the guide rod 1204 avoids the offset between the second sliding sleeve 1205 and the lifting ring 4, improving the overall operational stability of the device. When combined with the scale line 13 on the vertical rod 2, the precise positioning of the lifting height can be achieved.

[0030] In this embodiment, the forward and reverse motor 701, the first motor 1004, the second motor 1103 and the third motor 1203 used in this application are all prior art, and the connections between the components are also prior art, so their connection relationships and principles will not be described in detail here; in addition, the gears, gear rings and lead screws and other mechanical meshing transmission components used in this application are all provided with protective components to ensure their normal and stable operation.

[0031] In this embodiment, the rotatable connection between the lifting ring 4 and the rotating ring 6, and between the rotating ring 6 and the internal gear ring 1001, can be achieved by providing T-shaped blocks along the circumferential direction on the lifting ring 4 and the internal gear ring 1001, and providing T-shaped grooves on the rotating ring 6, with the T-shaped blocks rotatably embedded in the T-shaped grooves to achieve rotational engagement between the two. In addition, to facilitate rotation between the lifting ring 4 and the rotating ring 6, and between the rotating ring 6 and the internal gear ring 1001, multiple balls can be provided in the T-shaped grooves, with the balls limited by retainers, and the T-shaped blocks abutting against the balls for easy rotation. The above method is one installation method provided in this application, and other existing solid line rotational connection methods can also be used, which will not be described in detail in this application.

[0032] The working principle and usage procedure of this device are as follows: First, start the third motor 1203 to drive the double-headed threaded rod 1202 to rotate, which in turn drives the two second sliding sleeves 1205 to slide along the guide rod 1204. Through the transmission rod 1206, push the lifting ring 4 to move vertically along the first sliding sleeve 5 on the vertical rod 2. The vertical height of the cleaning component 11 is precisely adjusted by the scale line 13, so that the lifting ring 4 is coaxially set with the pipe to be cleaned. Then, the pipe to be cleaned is placed in the V-shaped placement groove 15, and the pipe and the sliding roller 17 protruding from the inclined surface in the V-shaped placement groove 15 form rolling contact. According to the pipe diameter, start the first motor 1004 to drive the rotating shaft 1002 in the synchronous drive unit 10 and the second gear. When wheel 1003 rotates, all second gears 1003 rotate synchronously through the internal gear ring 1001, driving the rack 9 of the annular array to move radially synchronously along the rotating ring 6, so that the cleaning roller brush 1102 fits tightly against the outer wall of the pipe. Then, the second motor 1103 and the forward and reverse motors 701 are started at the same time. The second motor 1103 drives the cleaning roller brush 1102 to rotate at high speed to form active decontamination. The forward and reverse motors 701 drive the rotating ring 6 to reciprocate around the pipe through the meshing of the first gear 702 and the external gear ring 703, so that the cleaning roller brush 1102 performs circumferential reciprocating cleaning along the outer wall of the pipe. Then, by pushing the pipe to roll on the sliding roller 17, axial displacement is achieved, and the outer wall of the pipe is thoroughly cleaned.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
