Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to a support structure for pipeline installation in water conservancy projects and its usage method. Background Art

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and bringing benefits. Most of the existing water resource allocations are transported through pipelines. The pipelines for transporting water sources are either directly buried underground or fixed on the ground through support devices. The pipelines placed on the ground are generally supported by support devices to ensure the stability of the pipelines.

[0003] However, the following disadvantages still exist in the support structure in the prior art during the connection of two adjacent pipelines:

[0004] 1. When the support structure connects pipelines, its connection end is relatively fragile, which easily leads to an insecure connection of the pipelines and causes vibration during water transportation, resulting in leakage at the connection.

[0005] 2. When connecting two pipelines, it is impossible to clean the connection ends of the pipelines, resulting in impurities attached to the ends affecting the sealing performance of the pipeline connection.

[0006] In view of the above problems, the present invention document proposes a support structure for pipeline installation in water conservancy projects and its usage method. Summary of the Invention

[0007] The purpose of the present invention is to solve the disadvantages of the insecure connection between existing pipelines and the inability to clean the connection ends of the pipelines, and to propose a support structure for pipeline installation in water conservancy projects and its usage method.

[0008] To achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A support structure for pipeline installation in water conservancy projects includes a base. Two moving seats are slidably provided on the top of the base. Pipe supports are fixed at the tops of the two moving seats for supporting pipelines. Four connecting arms are slidably penetrated through each of the two pipe supports, and the four connecting arms are used for clamping and fixing the pipelines.

[0010] It further includes a first support plate slidably fitted on the top of the base, and the first support plate is located at the central position between the two moving seats. A rotating ring is rotatably connected to the top of the first support plate. A cylindrical steel brush is provided inside the rotating ring for cleaning the ends of the pipelines, and cleaning brush plates are provided on both sides of the rotating ring for cleaning the outer walls of the pipelines.

[0011] The clamping structure is arranged inside the moving seat and is used to control the downward movement of the connecting arm to clamp and fix the pipeline.

[0012] The cleaning structure is arranged inside the rotating ring and is used to clean the end and outer wall of the pipeline.

[0013] In a possible design, the clamping structure includes a lifting groove arranged inside the moving seat. A lifting plate is slidably connected inside the lifting groove. Two of the four connecting arms are in a group and are respectively fixed on both sides of the top of the lifting plate. A threaded rod is longitudinally rotatably connected inside the lifting groove. The threaded rod is threadedly connected with the lifting plate. A first bevel gear is fixedly sleeved on the outer wall of the threaded rod and is located below the lifting plate. The bottom inner wall of the lifting groove is rotatably connected with a rotating rod through a fixed block. A second bevel gear meshing with the first bevel gear is fixed at one end of the rotating rod. The rotation of the threaded rod is driven by the cooperation of the first bevel gear and the second bevel gear to control the lifting of the lifting plate and the connecting arm. The second bevel gear is driven to rotate by the rotating rod, and the cooperation of the second bevel gear and the first bevel gear drives the lifting plate and the connecting arm to move downward. As the connecting arm descends, the roller abuts against the outer wall of the pipeline and cooperates with the pipe support to complete the clamping of the pipeline.

[0014] In a possible design, the clamping structure further includes a fixed shaft fixed inside the connecting arm. A clamping plate is rotatably sleeved on the outer wall of the fixed shaft. Two torsion springs are sleeved on the outer wall of the fixed shaft. One ends of the two torsion springs close to each other are respectively fixed to both sides of the clamping plate. The other ends of the two torsion springs far from each other are both fixed to the outer wall of the fixed shaft. The torsion spring is used to drive the clamping plate to rotate to a horizontal state. The top inner wall of the connecting arm cooperates with the top of the clamping plate to limit the rotation of the clamping plate. A roller is rotatably arranged inside the clamping plate and is used to abut against the outer wall of the pipeline. When the lifting plate and the connecting arm move downward, the clamping plate is horizontally placed under the action of the torsion spring, and the top inner wall of the connecting arm brakes the top of the clamping plate, so that the clamping plate is in a horizontal state. As the connecting arm descends, the roller abuts against the outer wall of the pipeline and cooperates with the pipe support to complete the clamping of the pipeline.

[0015] In a possible design, the cleaning structure includes an inner ring groove provided on the inner wall of the rotating ring. The bottom inner wall of the inner ring groove is rotatably connected to a rotating shaft. The top end of the rotating shaft is fixedly connected to the bottom end of a cylindrical steel brush. A double-groove synchronous pulley is fixedly sleeved on the outer wall of the rotating shaft. First bases are fixed on both sides of the rotating ring. A rotating cylinder rotatably penetrates through each of the two first bases. First synchronous pulleys are fixedly sleeved on the outer walls of the two rotating cylinders. The first synchronous pulley and the double-groove synchronous pulley are connected by a synchronous belt for transmission. Slide rods are slidably connected in the two rotating cylinders. The top ends of the two slide rods are respectively fixedly connected to the bottoms of two cleaning brush plates. Springs sleeved on the outer walls of the two slide rods and fixedly connected to the bottoms of the cleaning brush plates have their bottom ends fixed to the top ends of the corresponding rotating cylinders, for making the cleaning brush plates closely adhere to the outer wall of the pipeline. The cleaning brush plates and the cylindrical steel brush are connected by the first synchronous pulley, the double-groove synchronous pulley and the synchronous belt for transmission to clean the pipeline. When two pipelines are inserted into the rotating ring, the rotating ring starts to rotate. The third bevel gear meshes with the bevel gear ring to drive the rotating cylinder to rotate. The rotating cylinder drives the cleaning brush plate to rotate through the slide rod. And the cleaning brush plate closely adheres to the outer wall of the pipeline under the action of the slide rod. Therefore, the cleaning brush plate can clean the outer wall of the pipeline. The rotating cylinder drives the double-groove synchronous pulley, the rotating shaft and the cylindrical steel brush to rotate synchronously through the synchronous belt. When the two pipelines approach each other and both are in contact with the cylindrical steel brush, the rotating cylindrical steel brush can clean one end of the pipeline.

[0016] In a possible design, the cleaning structure further includes an annular groove provided on the outer wall of the rotating ring. A straight-tooth ring is fixed in the annular groove. A placement groove is provided at the top of the first support plate. A motor is fixed on the bottom inner wall of the placement groove. A straight gear meshing with the straight-tooth ring is fixed to the output shaft of the motor. The motor drives the rotating ring to rotate through the cooperation of the straight gear and the straight-tooth ring. Third bevel gears are fixed to the bottom ends of the two rotating cylinders. A bevel gear ring is rotatably connected to one side of the rotating ring, and the bevel gear ring meshes with the third bevel gear. The bottom of the bevel gear ring is fixed with an L-shaped support plate, and the L-shaped support plate is fixed to one side of the first support plate. When the rotating ring rotates, it drives the cleaning brush plate and the cylindrical steel brush to rotate through the cooperation of the third bevel gear and the bevel gear ring. By driving the straight gear to rotate by the motor, the cooperation of the straight gear and the straight-tooth ring drives the rotating ring to rotate on the top of the first support plate. The rotating ring drives the first base, the cleaning brush plate and the third bevel gear to rotate. The third bevel gear meshes with the bevel gear ring. The bevel gear ring drives the rotating cylinder to rotate through the third bevel gear. The rotating cylinder drives the cleaning brush plate to rotate. The cleaning brush plate closely adheres to the outer wall of the pipeline under the action of the slide rod. Therefore, the cleaning brush plate can clean the outer wall of the pipeline.

[0017] In a possible design, two movable grooves are provided on the top of the base, and the same bidirectional screw rod is rotatably connected in the two movable grooves, and one end of the bidirectional screw rod rotates and extends to one side of the base, and a T-shaped slider threadedly connected to the bidirectional screw rod is slidably connected in the two movable grooves, and the two T-shaped sliders are respectively located on the positive and negative thread sections of the bidirectional screw rod, and the top ends of the two T-shaped sliders are respectively fixedly connected to the bottom ends of the corresponding movable seats, and the cooperation between the bidirectional screw rod and the T-shaped slider is used to control the two movable seats to move toward each other.

[0018] In a possible design, two positioning grooves are provided at the top of the base, and the two positioning grooves are respectively located on both sides of the first support bracket, and a second base is fixed on both sides of the first support bracket, and vertical rods are slid through the two second bases, and the outer walls of the two vertical rods are sleeved with tension springs fixedly connected to the top of the second base, and the top ends of the two tension springs are respectively fixedly connected to the outer walls of the corresponding vertical rods, and the bottom ends of the two vertical rods are fixed with mounting seats, and the bottoms of the two mounting seats are embedded with balls, and the balls cooperate with the positioning grooves to position the first support bracket; the first support bracket is slid on the base until the balls enter the positioning grooves under the tension of the tension springs to position the first support bracket, and at this time the first support bracket is located on the center line between the two movable seats, and when the two movable seats are close to each other, the two pipes can be inserted into the rotating ring.

[0019] In one possible design, the rotating ring is provided with a plurality of inclined holes connected to the inner ring groove, and one end of the inclined hole extends to one side of the rotating ring, which is used to discharge the slag in the inner ring groove to the outside. The outer wall of the rotating ring is provided with a plurality of T-shaped ring grooves, and a plurality of T-shaped arc plates are fixed on the top of the first support plate, and the T-shaped arc plates are slidably matched with the T-shaped ring grooves to increase the stability of the rotating ring on the top of the first support plate.

[0020] In one possible design, the top of the base is slidably engaged with a movable platform, and the top of the movable platform is slidably penetrated by a lead screw, and the top of the lead screw is fixed with a second support plate for lifting the two pipe connection ends, and the top of the movable platform is rotatably connected to a nut threadedly connected to the lead screw, and the outer wall of the nut is fixed with multiple levers; when the two pipes are docked and welded, the movable platform is moved to the bottom of the pipe connection, and the nut is rotated by the lever, and the nut drives the lead screw and the second support plate to move up, and the second support plate lifts the two pipe connection ends, thereby increasing the stability of the connection ends and avoiding pipeline vibration during water transportation.

[0021] In this application, a method for using a support structure for pipe installation in a water conservancy project comprises the following steps:

[0022] S1. Pipe clamping: Place two pipes on two pipe supports, respectively. Rotate the rotating lever to drive the second bevel gear, which cooperates with the first bevel gear to drive the lifting plate and connecting arm downward. The clamping plate is placed horizontally under the action of the torsion spring, and the inner wall of the top of the connecting arm brakes the clamping plate to keep it horizontal. When the connecting arm descends, the roller contacts the outer wall of the pipe and cooperates with the pipe support to complete the clamping.

[0023] S2. Preparation for pipe docking: Rotate the bidirectional screw rod to drive the two pipe supports closer to each other through the T-shaped slider, so that the two pipes are close to each other;

[0024] S3. Positioning the first support plate: Slide the first support plate onto the base until the ball enters the positioning groove under the tension of the tension spring, thereby positioning the first support plate. At this time, the first support plate is located on the center line between the two movable seats. When the two movable seats approach each other, the two pipes are driven to insert into the rotating ring.

[0025] S4. Cleaning the outer wall of the pipeline: The motor drives the spur gear to rotate, which cooperates with the spur gear ring to drive the rotating ring to rotate on the top of the first support plate. The rotating ring drives the first base, the cleaning brush plate and the third bevel gear to rotate. The third bevel gear meshes with the bevel gear ring to drive the rotating drum to rotate. The rotating drum drives the cleaning brush plate to rotate via the sliding rod, closely following the outer wall of the pipeline for cleaning.

[0026] S5. Cleaning the pipe ends and discharging debris: The rotating drum drives the double-grooved synchronous wheel, rotating shaft, and cylindrical steel brush to rotate synchronously via a synchronous belt. When two pipes approach each other and are both in contact with the cylindrical steel brush, the rotating cylindrical steel brush cleans one end of the pipe. As the rotating ring rotates, the debris generated by the cylindrical steel brush is discharged to the outside through the inclined hole. After cleaning, the pipe is removed and the first support plate is taken out.

[0027] S6. Lifting the pipe connection ends: After the two pipes are butt-jointed and welded, move the movable platform to the bottom of the pipe connection; rotate the nut by using the lever to drive the lead screw and the second support plate to move up, thereby lifting the two pipe connection ends.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, a clamping plate is rotatably sleeved on the outer wall of the fixed shaft, and the top inner wall of the connecting arm cooperates with the top of the clamping plate to place the clamping plate horizontally. A roller is rotatably provided in the clamping plate to abut against the outer wall of the pipe. Four connecting arms are fixed in groups of two on both sides of the top of the lifting plate, and a threaded rod is connected to the lifting groove for longitudinal rotation. The threaded rod rotates to drive the lifting plate and the connecting arm to move downward, and the roller abuts against the outer wall of the pipe and cooperates with the pipe support to complete the clamping of the pipe, which not only facilitates the insertion of the pipe into the rotating ring for cleaning later, but also increases the stability of the pipe.

[0030] In the present invention, a lead screw slidably penetrates through the top of the mobile station. The top end of the lead screw is fixed with a second support plate. The top of the mobile station is rotatably connected with a nut threadedly connected to the lead screw. After the two pipes are docked and welded, the mobile station is moved below the pipe connection. The rotation of the nut drives the lead screw and the second support plate to move upward, and the second support plate lifts the two pipe connection ends, increasing the stability of the connection ends and avoiding the vibration of the pipes during water transportation.

[0031] In the present invention, the bottom inner wall of the inner ring groove is rotatably connected with a rotating shaft. The top end of the rotating shaft is fixedly connected with the bottom end of the cylindrical steel brush. A rotating cylinder rotatably penetrates through the first base. The rotating cylinder and the rotating shaft are connected by a double-groove synchronous pulley, a first synchronous pulley and a synchronous belt. A sliding rod is slidably connected in the rotating cylinder. The top end of the sliding rod is fixedly connected with the bottom of the cleaning brush plate. When the rotating ring starts to rotate, the third bevel gear meshes with the bevel gear ring to drive the rotating cylinder to rotate. The rotating cylinder drives the rotating shaft to rotate. Thus, the cleaning brush plate and the cylindrical steel brush can rotate synchronously to clean the outer wall and the end of the pipe, facilitating the subsequent docking between the two pipes.

[0032] In the present invention, through the cooperation of the pipe support, the connecting arm and the second support plate, the middle part and the docking end of the pipe can be lifted, greatly increasing the stability of the pipe. And when one end of the pipe is inserted into the rotating ring, through the rotation of the rotating ring, the cleaning brush plate and the cylindrical steel brush can be driven to clean the outer wall and the end of the pipe, facilitating the subsequent docking between the two pipes.

[0046] 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.

[0047] Embodiment 1: Refer to Figures 1 - 3 , a support structure, which relates to the technical field of water conservancy projects. Its structure includes a base 1. Two moving seats 2 are slidably arranged on the top of the base 1. Pipe supports 3 are fixed to the tops of the two moving seats 2 for supporting pipelines. Four connecting arms 9 are slidably penetrated through both of the two pipe supports 3, and the four connecting arms 9 are used for clamping and fixing the pipeline.

[0048] Refer to Figure 1 , Figure 6 , Figure 8 and Figure 9 , further, the support structure further includes a first support plate 18 slidably fitted on the top of the base 1, and the first support plate 18 is located at the central position between the two moving seats 2. A rotating ring 19 is rotatably connected to the top of the first support plate 18. A cylindrical steel brush 37 is arranged inside the rotating ring 19 for cleaning the end of the pipeline. Cleaning brush plates 32 are arranged on both sides of the rotating ring 19 for cleaning the outer wall of the pipeline.

[0049] Refer to Figure 3 and Figure 5 , in order to realize the clamping and fixing of the pipeline by the connecting arms 9, a clamping structure is provided in this embodiment, which specifically includes a lifting groove 7 arranged in the moving seat 2. A lifting plate 8 is slidably connected in the lifting groove 7. The four connecting arms 9 are fixed to both sides of the top of the lifting plate 8 in two groups. A threaded rod 14 is longitudinally rotatably connected in the lifting groove 7, and the threaded rod 14 is threadedly connected to the lifting plate 8. A first bevel gear 15 is fixedly sleeved on the outer wall of the threaded rod 14 and is located below the lifting plate 8. A rotating rod 17 is rotatably connected to the bottom inner wall of the lifting groove 7 through a fixed block. A second bevel gear 16 meshing with the first bevel gear 15 is fixed to one end of the rotating rod 17. By rotating the rotating rod 17, the second bevel gear 16 can be driven to rotate. The cooperation between the second bevel gear 16 and the first bevel gear 15 drives the threaded rod 14 to rotate, thereby controlling the lifting of the lifting plate 8 and the connecting arms 9.

[0050] Refer to Figure 3 and Figure 4, Further, the clamping structure further includes a fixed shaft 10 fixed inside the connecting arm 9, and a clamping plate 12 is rotatably sleeved on the outer wall of the fixed shaft 10. Two torsion springs 11 are sleeved on the outer wall of the fixed shaft 10. One end of the two torsion springs 11 close to each other is fixedly connected to both sides of the clamping plate 12 respectively, and the other end of the two torsion springs 11 away from each other is fixedly connected to the outer wall of the fixed shaft 10. The torsion spring 11 is used to drive the clamping plate 12 to rotate to a horizontal state. The inner wall of the top of the connecting arm 9 cooperates with the top of the clamping plate 12 to limit the rotation of the clamping plate 12. A roller 13 is rotatably arranged inside the clamping plate 12 for abutting against the outer wall of the pipeline. When the lifting plate 8 and the connecting arm 9 move downward, the clamping plate 12 is horizontally placed under the action of the torsion spring 11, and the inner wall of the top of the connecting arm 9 forms a brake on the top of the clamping plate 12, so that the clamping plate 12 is in a horizontal state. As the connecting arm 9 descends, the roller 13 abuts against the outer wall of the pipeline and cooperates with the pipe support 3 to complete the clamping of the pipeline.

[0051] Refer to Figures 6 - 9 , In order to clean the end and outer wall of the pipeline, a cleaning structure is provided in this embodiment, and this structure is arranged inside the rotating ring 19. When the pipeline is clamped, the rotating ring 19 can be rotated to make the cylindrical steel brush 37 clean the end of the pipeline. At the same time, the cleaning brush plates 32 on both sides of the rotating ring 19 clean the outer wall of the pipeline.

[0052] Refer to Figures 6 - 9 , The cleaning structure mainly includes parts such as a rotating ring 19, an inner ring groove 39, a rotating shaft 36, a cylindrical steel brush 37, a double-groove synchronous pulley 38, a first base 29, a rotating cylinder 30, a sliding rod 31, a cleaning brush plate 32, a spring 33, etc. The inner wall of the rotating ring 19 is provided with an inner ring groove 39, and the bottom inner wall of the inner ring groove 39 is rotatably connected to a rotating shaft 36. The top end of the rotating shaft 36 is fixedly connected to the bottom end of the cylindrical steel brush 37. In this way, when the rotating shaft 36 rotates, it will drive the cylindrical steel brush 37 to rotate together. A double-groove synchronous pulley 38 is fixedly sleeved on the outer wall of the rotating shaft 36. On both sides of the rotating ring 19, two first bases 29 are fixed. A rotating cylinder 30 is rotatably penetrated through both of the first bases 29, and a first synchronous pulley 35 is fixedly sleeved on the outer wall of the rotating cylinder 30. The first synchronous pulley 35 and the double-groove synchronous pulley 38 are connected by a synchronous belt. In this way, when the rotating cylinder 30 rotates, it will drive the double-groove synchronous pulley 38, the rotating shaft 36, and the cylindrical steel brush 37 to rotate synchronously through the synchronous belt.

[0053] Refer to Figure 9 , Inside the rotating cylinder 30, a sliding rod 31 is slidably connected, and the top end of the sliding rod 31 is fixedly connected to the bottom of the cleaning brush plate 32. A spring 33 fixedly connected to the bottom of the cleaning brush plate 32 is sleeved on the outer wall of the sliding rod 31, and the bottom end of the spring 33 is fixed to the top end of the corresponding rotating cylinder 30. In this way, the spring 33 will generate an upward thrust on the cleaning brush plate 32 to make the cleaning brush plate 32 closely adhere to the outer wall of the pipeline.

[0054] Refer to Figure 7 and Figure 8 In addition, we have provided an annular groove 22 on the outer wall of the rotating ring 19, and a straight-tooth ring 23 is fixed in the annular groove 22. A placement groove 24 is provided at the top of the first support plate 18, and a motor 26 is fixed to the inner wall of the bottom of the placement groove 24. A spur gear 25 meshing with the straight-tooth ring 23 is fixed to the output shaft of the motor 26. In this way, when the motor 26 drives the spur gear 25 to rotate, the rotating ring 19 will be driven to rotate through the cooperation of the spur gear 25 and the straight-tooth ring 23.

[0055] Refer to Figures 7 - 9 At the bottom ends of both rotating cylinders 30, a third bevel gear 34 is fixed. One side of the rotating ring 19 is rotatably connected to a bevel-gear ring 28, and the bevel-gear ring 28 meshes with the third bevel gear 34. At the bottom of the bevel-gear ring 28, an L-shaped support plate 27 is fixed, and the L-shaped support plate 27 is fixed to one side of the first support plate 18. In this way, when the rotating ring 19 rotates, the rotating cylinder 30 will be driven to rotate through the cooperation of the third bevel gear 34 and the bevel-gear ring 28, thereby driving the cleaning brush plate 32 and the cylindrical steel brush 37 to rotate.

[0056] In actual use, when two pipes are inserted into the rotating ring 19, we start the motor 26. The motor 26 drives the spur gear 25 to rotate, and the cooperation between the spur gear 25 and the straight-tooth ring 23 drives the rotating ring 19 to rotate. The rotating ring 19 drives the first base 29, the cleaning brush plate 32, and the third bevel gear 34 to rotate. The third bevel gear 34 meshes with the bevel-gear ring 28, and the bevel-gear ring 28 drives the rotating cylinder 30 to rotate through the third bevel gear 34. The rotating cylinder 30 drives the cleaning brush plate 32 to rotate through the sliding rod 31, and the cleaning brush plate 32 is closely attached to the outer wall of the pipe under the action of the sliding rod 31 and the spring 33; therefore, the cleaning brush plate 32 can clean the outer wall of the pipe. At the same time, the rotating cylinder 30 drives the double-groove synchronous pulley 38, the rotating shaft 36, and the cylindrical steel brush 37 to rotate synchronously through the synchronous belt. When the two pipes approach each other and are both in contact with the cylindrical steel brush 37, the rotating cylindrical steel brush 37 can clean one end of the pipe.

[0057] Refer to Figure 2 On the top of the base 1, we have provided two moving grooves 4. A bidirectional lead screw 5 is rotatably connected in these two moving grooves 4, and one end of the bidirectional lead screw 5 rotatably extends to one side of the base 1 for convenient external operation. In the moving grooves 4, two T-shaped sliders 6 are slidably connected, and these two T-shaped sliders 6 are respectively threadedly connected to the positive and negative threaded sections of the bidirectional lead screw 5. In this way, when the bidirectional lead screw 5 rotates, the two T-shaped sliders 6 will move towards or away from each other along the moving grooves 4. The top ends of the T-shaped sliders 6 are respectively fixedly connected to the bottom ends of the two moving seats 2. Therefore, through the cooperation of the bidirectional lead screw 5 and the T-shaped sliders 6, we can control the two moving seats 2 to move towards each other, thereby adjusting the distance between the two support structure bodies to adapt to pipes of different lengths.

[0058] Referring to Figure 2 、 Figure 8 and Figure 10 ,On the top of the base 1, two positioning grooves 46 are designed, and these two positioning grooves 46 are respectively located on both sides of the first support plate 18. In order to increase the positioning accuracy and stability of the first support plate 18 on the base 1, we have fixed second bases 41 on both sides of the first support plate 18. A vertical rod 42 is slidably penetrated through each second base 41. A tension spring 43 is sleeved on the outer wall of the vertical rod 42. The bottom end of the tension spring 43 is fixedly connected to the top of the second base 41, while the top end of the tension spring 43 is fixedly connected to the outer wall of the vertical rod 42. In this way, when the first support plate 18 slides on the base 1, the vertical rod 42 will move along with the movement of the first support plate 18, and at the same time, the tension spring 43 will be stretched or compressed.

[0059] Specifically, when the first support plate 18 slides to a suitable position, due to the pulling force of the tension spring 43, the mounting seat 44 at the bottom end of the vertical rod 42 will bring the ball 45 into the positioning groove 46, thereby positioning the first support plate 18. At this time, the first support plate 18 is located on the center line between the two moving seats 2. When the two moving seats 2 approach each other, the two pipes can be smoothly inserted into the rotating ring 19.

[0060] Referring to Figure 7 and Figure 8 ,In the rotating ring 19, we have designed a plurality of inclined holes 40 communicating with the inner ring groove 39. One end of these inclined holes 40 extends to one side of the rotating ring 19 for discharging the slag in the inner ring groove 39 to the outside. In this way, when the rotating ring 19 rotates, the slag in the inner ring groove 39 can be smoothly discharged through the inclined holes 40, avoiding the slag from hindering the rotation of the rotating ring 19. At the same time, on the outer wall of the rotating ring 19, we have designed a plurality of T-shaped ring grooves 20, and on the top of the first support plate 18, we have fixed a plurality of T-shaped arc plates 21 that are slidably matched with the T-shaped ring grooves 20. In this way, when the rotating ring 19 is placed on the first support plate 18, the T-shaped arc plates 21 will slide into the T-shaped ring grooves 20, thereby increasing the stability of the rotating ring 19 on the top of the first support plate 18.

[0061] Through the above implementation manner, the support structure for pipeline installation in water conservancy projects provided by this embodiment can conveniently clamp and fix the pipeline. At the same time, it can also clean the end and outer wall of the pipeline, improving the efficiency and quality of pipeline installation.

[0062] Embodiment 2: Refer to Figure 11 and Figure 12, on the basis of Embodiment 1, an improvement is made: on the top of the base 1, we designed a slidable moving platform 47. On the top of the moving platform 47, we slid a lead screw 49 through it, and a second supporting plate 48 for lifting the two pipe connection ends is fixed at the top of the lead screw 49. On the top of the moving platform 47, we also rotatably connected a nut 50 that is threadedly connected to the lead screw 49. A plurality of lever rods 51 are fixed on the outer wall of the nut 50, which is convenient for us to manually turn the nut 50. After the two pipes are docked and welded, we can move the moving platform 47 to the lower part of the pipe connection. Then, by turning the nut 50 with the lever rod 51, the nut 50 will drive the lead screw 49 and the second supporting plate 48 to move upward. When the second supporting plate 48 rises to a suitable position, it will lift the connection ends of the two pipes, thereby increasing the stability of the connection ends and avoiding pipe vibration during water transportation.

[0063] The usage method of the support structure for pipe installation in water conservancy projects includes the following steps:

[0064] S1. Place the two pipes on the two pipe supports 3 respectively. When it is necessary to clamp the pipes, rotate the rotating rod 17 to drive the second bevel gear 16 to rotate. The cooperation between the second bevel gear 16 and the first bevel gear 15 drives the lifting plate 8 and the connecting arm 9 to move downward. In addition, the clamping plate 12 is horizontally placed under the action of the torsion spring 11, and the inner wall of the top of the connecting arm 9 forms a brake on the top of the clamping plate 12, so that the clamping plate 12 is in a horizontal state. As the connecting arm 9 descends, the roller 13 abuts against the outer wall of the pipe and cooperates with the pipe support 3 to complete the clamping of the pipe;

[0065] S2. When it is necessary to dock the two pipes, rotate the bidirectional lead screw 5. The bidirectional lead screw 5 drives the two pipe supports 3 to approach each other through the T-shaped slider 6, so that the two pipes can approach each other;

[0066] S3. Before the two pipes approach each other, slide the first supporting plate 18 on the base 1 until the ball 45 enters the positioning groove 46 under the pulling force of the tension spring 43 to position the first supporting plate 18. At this time, the first supporting plate 18 is located on the center line between the two moving seats 2. When the two moving seats 2 approach each other, drive the two pipes to be inserted into the rotating ring 19;

[0067] S4. To ensure the sealing performance when two pipes are connected, it is necessary to clean the butt ends and outer walls of the two pipes. Specifically, the motor 26 drives the spur gear 25 to rotate. The cooperation between the spur gear 25 and the spur gear ring 23 drives the rotating ring 19 to rotate on the top of the first support plate 18. The rotating ring 19 drives the first base 29, the cleaning brush plate 32 and the third bevel gear 34 to rotate. The third bevel gear 34 meshes with the bevel gear ring 28. The bevel gear ring 28 drives the rotating cylinder 30 to rotate through the third bevel gear 34. The rotating cylinder 30 drives the cleaning brush plate 32 to rotate through the slide bar 31. And the cleaning brush plate 32 closely adheres to the outer wall of the pipe under the action of the slide bar 31. Therefore, the cleaning brush plate 32 can clean the outer wall of the pipe.

[0068] S5. In addition, the rotating cylinder 30 drives the double-groove synchronous pulley 38, the rotating shaft 36 and the cylindrical steel brush 37 to rotate synchronously through the synchronous belt. When the two pipes approach each other and both are in contact with the cylindrical steel brush 37, the rotating cylindrical steel brush 37 can clean one end of the pipe, ensuring the cleanliness of the approaching ends of the two pipes and facilitating the subsequent docking of the two pipes. In addition, when the rotating ring 19 rotates, the debris generated during the cleaning process of the cylindrical steel brush 37 can be discharged to the outside through the inclined holes 40. After the outer wall and the end of the pipe are cleaned, the two pipes are removed from the rotating ring 19, and then the first support plate 18 is taken out from the base 1 for convenient subsequent use.

[0069] S6. When the two pipes are docked and welded, the mobile platform 47 is moved below the pipe connection. The nut 50 is rotated by the lever 51. The nut 50 drives the lead screw 49 and the second support plate 48 to move upward. The second support plate 48 lifts the connection ends of the two pipes, increasing the stability of the connection ends and avoiding the vibration of the pipes during the water transportation process.

[0070] However, as is well known to those skilled in the art, the working principle and wiring method of the motor 26 are common knowledge, and they both belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0071] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
