Description

Technical Field

[0001] This invention relates to the field of dredging engineering technology, and in particular to a modular floating device for use in sludge discharge pipelines and a method for installing sludge discharge pipelines. Background Technology

[0002] Sludge discharge pipelines are crucial equipment in dredging projects, serving to transport sludge. These pipelines, typically several kilometers long, are equipped with buoys at the bottom to maintain buoyancy and stability. With technological advancements and the continuous upgrading of dredging equipment, the inner diameter of sludge discharge pipelines used in recent years has been steadily increasing, from a maximum of 900mm to 1000mm, 1100mm, and even 1200mm. This has led to a proliferation of different pipe diameters, ranging from a minimum of 450mm to over ten different sizes. Furthermore, considering the varying soil conditions, each pipe diameter has a different wall thickness, resulting in approximately thirty different types of support clamps. This necessitates the construction team preparing a wide variety of clamps, which is time-consuming and labor-intensive.

[0003] Chinese Patent Publication No. CN219952093U discloses a float applicable to sludge discharge pipes of different sizes, including an upper float and a lower float. The inner walls of the upper and lower floats are provided with support plates, and multiple sets of springs are provided on the inner walls of the support plates. The compression of the springs adapts to sludge discharge pipes of different sizes. Since this device clamps the sludge discharge pipe by compressing the springs, if the springs are longer, the compression force in the later stages will be very large, which will easily cause difficulties in installing the upper and lower floats. Therefore, the spring length cannot be too long, and it can only adapt to a small range of sludge discharge pipe size changes, which makes it impossible to meet the needs of large-size pipe diameter changes from 450mm to 1200mm. Chinese patent publication number CN220337625U discloses a modular pontoon for subsea pipelines, which has a detachable connecting accessory installed on its upper part. The wedge block is selected according to the outer diameter of the subsea pipeline, and then the wedge block is fixed into the groove by bolts. This method requires manual replacement of the wedge block for different pipe diameters, which is time-consuming and labor-intensive. Moreover, the pontoons corresponding to various pipe diameters are also different. The length of the pontoons is more than 4m, 5m, 6m, and even 7m. The size is getting larger and larger, which is not convenient for transportation. The types of pontoons are also increasing, which brings management difficulties to the project management party.

[0004] In addition, existing pontoons are generally made of welded steel, and some welds are of poor quality. Coupled with long-term immersion in water, they will rust and easily cause the pontoons to leak. Furthermore, the existing pontoons cannot change their buoyancy. When the sludge discharge pipelines are connected to each other, there will be a misalignment between the pontoons. At this time, the axes of the sludge discharge pipelines are not on the same plane, making it difficult to connect the flange bolts. Summary of the Invention

[0027] Example Please see Figures 1-9 This embodiment provides a modular floating device for sludge discharge pipelines, including a floating body assembly, a sludge discharge pipe support mechanism 3, a clamping strap 2, and a hydraulic pump station 8. The floating body assembly is composed of multiple floating body modules 6 spliced ​​together. Depending on the diameter, length, and concentration of the medium within the sludge discharge pipeline 1 (i.e., different load-bearing capacities), the floating body modules 6 can be spliced ​​together to form various floating body assemblies, resulting in different configurations. The sludge discharge pipe support mechanism 3 is installed above the floating body modules 6 to support the sludge discharge pipeline 1. The clamping strap 2 connects the sludge discharge pipeline 1 to the floating body modules 6. The sludge discharge pipeline 1 is mounted on the floating body assembly via at least two sludge discharge pipe support mechanisms 3 and at least one clamping strap 2.

[0028] The sludge discharge pipe support mechanism 3 is adjustable, capable of adapting to sludge discharge pipelines 1 with different diameters and wall thicknesses.

The supporting telescopic rod 3-2 of the adjusting cylinder is rotatably connected to the support roller 3-1. The hydraulic quick connector 3-7 on the cylinder body 3-5 is connected to the hydraulic quick connector 8-12 of the hydraulic pump station 8. The adjusting cylinder controls the distance between the two support rollers 3-1. The length of the supporting telescopic rod 3-2 is adjusted according to the diameter and wall thickness of the sludge discharge pipeline 1 to adapt to pipelines with different diameters and wall thicknesses, thus providing support.

[0029] In a preferred embodiment, the top of the float module 6 is provided with an upper float mounting seat 6-3, and the bottom of the support body 3-10 is provided with a lower support mounting seat 3-11. The upper float mounting seat 6-3 and the lower support mounting seat 3-11 are sleeved together and connected and locked by a pin 7, which is convenient for installation. After the clamping strap 2 clamps the sludge discharge pipeline 1, it is connected to the upper float mounting seat 6-3. The clamping strap 2 cooperates with the sludge discharge pipeline support mechanism 3 to ensure that the sludge discharge pipeline 1 is stably installed.

[0030] In a preferred embodiment, the floating module 6 has a cubic structure and is made of HDPE (high-density polyethylene) material, which has high tensile strength, enabling it to withstand high stress or high force without breaking or deforming, reducing the risk of rust and leakage, and improving service life.

[0031] In a preferred embodiment, the floating module 6 includes a splicing plate 6-1 on its top, and bosses 6-5 and grooves 6-6 on its sides. When two adjacent floating modules 6 are connected, the top splicing plate 6-1 is connected by bolts, and the bosses 6-5 and grooves 6-6 on the sides cooperate. The top of the floating module 6 is also provided with a water inlet 6-2 and lifting lugs 6-4. The water inlet 6-2 is used to inject or pump water to adjust the attitude of the floating assembly. A cover plate 4 is provided at the water inlet 6-2, which serves as a protective cover for the water inlet 6-2 and closes the water inlet 6-2 when no water injection is needed. The lifting lugs 6-4 are used to lift the floating module 6. Specifically, splicing plates 6-1 are provided on all four sides of the top of the floating module 6, bosses 6-5 and grooves 6-6 are provided on two sides, and a water inlet 6-2 and four lifting lugs 6-4 are provided on the top, with the four lifting lugs 6-4 located near the four corners of the floating module 6.

[0032] In a preferred embodiment, the float assembly is equipped with a bollard 5 for towing the float assembly on water. In this embodiment, for ease of installation, the bollard 5 is installed at the water inlet 6-2, and the cover plate 4 is then installed on the bollard 5.

[0033] In a preferred embodiment, the support further includes a locking component for locking the support telescopic rod 3-2. The locking component includes a clamping sleeve 3-4 and a locking nut 3-5. One end of the clamping sleeve 3-4 is annular, passing through the support telescopic rod 3-2 and connecting to the cylinder body 3-5 of the adjusting cylinder. The other end is a conical plastic body, which is compressed under the turning of the locking nut 3-5, thereby clamping the support telescopic rod 3-2 to complete the mechanical locking and ensure stable support.

[0034] In a preferred embodiment, the two ends of the support roller 3-1 are rotatably connected to the support rods 3-9, and the support rods 3-9 are rotatably connected to the support body 3-10; the cylinder body 3-5 of the adjusting cylinder is rotatably mounted on the adjusting device base 3-8 via the cylinder body support shaft 3-6, and the adjusting device base 3-8 is mounted on the support body 3-10. Specifically, the two ends of the support roller 3-1 are rotatably connected to one end of the support rod 3-9, and the other end of the support rod 3-9 is rotatably connected to the support body 3-10; the middle part of the cylinder body 3-5 of the adjusting cylinder is rotatably mounted on the adjusting device base 3-8 via the cylinder body support shaft 3-6; the adjusting device base 3-8 is mounted on the support body 3-10; the end of the supporting telescopic rod 3-2 of the adjusting cylinder is rotatably connected to the middle of the support roller 3-1; and the hydraulic oil pipe quick connectors 3-7 are located near both ends of the cylinder body 3-5 of the adjusting cylinder. The reasonable size design of each component makes it easier to adjust the support roller 3-1 over a wide range, thereby adapting to sludge discharge pipelines 1 with different diameters.

[0035] In a preferred embodiment, the hydraulic pump station 8 is used to drive the adjusting cylinder of the mud discharge pipe support mechanism 3, thereby adjusting the distance between the two support rollers 3-1. The hydraulic pump station 8 includes both electric and manual systems. The electric system includes a motor pump group 8-1, a one-way valve 8-6, a safety valve 8-8, a speed regulating valve 8-9, a solenoid directional valve 8-5, and a hydraulic lock 8-10 connected in sequence. The manual system includes a hand-cranked pump group 8-2, a one-way valve 8-7, a manual directional valve 8-4, and a hydraulic lock 8-11 connected in sequence. Both the motor pump group 8-1 and the hand-cranked pump group 8-2 draw hydraulic oil from the hydraulic oil tank 8-3. Both the hydraulic lock 8-10 and the hydraulic lock 8-11 are connected to the hydraulic oil pipe quick connector 8-12.

[0036] In dredging projects, the diameter, length, and concentration of the medium inside the sludge discharge pipe vary, resulting in different load-bearing capacities and requiring various types of floats. Therefore, this invention designs various floats composed of different numbers of float modules 6, used to bear weight on the water. A sludge discharge pipe support mechanism 3 is connected above the float module 6, supporting the sludge discharge pipe 1 at its upper part and connecting to the float module 6 at its lower part via a pin 7. The sludge discharge pipe support mechanism 3 is adjustable to accommodate sludge discharge pipes 1 of different diameters. A hydraulic pump station 8 drives the adjusting cylinder of the sludge discharge pipe support mechanism 3 to adjust the distance between the two support rollers 3-1. A clamping strap 2 is used to secure the sludge discharge pipe 1 to the float module 6, preventing it from swaying. A detachable bollard 5 can be installed at an appropriate position in the assembled float assembly for towing the float assembly on the water. The cover plate 4 is installed on the floating module 6 or on the bollard 5, serving as a protective cover for the water inlet 6-2, and closing the water inlet when no water is needed. This invention standardizes the size of the floating module, allowing it to be assembled into various floating assemblies to adapt to sludge discharge pipelines of different sizes and weights, facilitating management by the user; at the same time, compared with the traditional large-diameter sludge pipe floats, it greatly reduces the volume, making it easier to transport.

[0037] A method for installing a sludge discharge pipeline includes the following steps: S1. Calculate the buoyancy requirements based on the diameter, length, and concentration of the medium in the sludge discharge pipeline 1. Then design the number and combination of the floating modules 6 to form a floating group. S2. Install the sludge discharge pipe support mechanism 3 above the floating body module 6; then connect the hydraulic oil pipe quick connector 8-12 of the hydraulic pump station 8 to the hydraulic oil pipe quick connector 3-7 of the sludge discharge pipe support mechanism 3, control the adjusting cylinder to adjust the extension length of the support telescopic rod 3-2, and adjust the distance between the two support rollers 3-1 to adapt to the outer wall of the sludge discharge pipe 1. S3. Hoist the sludge discharge pipeline 1 onto the upper part of the sludge discharge pipe support mechanism 3, and then use the clamp 2 to connect the sludge discharge pipeline 1 to the floating body module 6, so that the sludge discharge pipeline 1 is stably installed above the floating body assembly.

[0038] In one preferred embodiment, after the support roller 3-1 is adjusted into place, the locking nut 3-5 is turned to compress the clamping sleeve 3-4, thereby clamping the support telescopic rod 3-2 and completing the mechanical locking.

[0039] To better understand the technical solution of the present invention, the present invention will be further described in detail below: The modular floating device applied to the sludge discharge pipeline 1 includes the sludge discharge pipeline 1, the clamping belt 2, the sludge discharge pipeline support mechanism 3, the cover plate 4, the cable bollard 5, the floating module 6, the pin shaft 7, and the hydraulic pump station 8.

[0040] The floating module 6 can be assembled into various floating groups, and different shapes can be combined according to the different pipe diameter, pipe length, and medium concentration in the pipe of the sludge discharge pipeline 1, i.e. different load-bearing capacities.

[0041] The floating module 6 has a cubic structure and is made of HDPE material.

[0042] The floating module 6 includes a splicing plate 6-1 at the top, a water inlet 6-2, a floating upper mounting base 6-3, a lifting lug 6-4, and a boss 6-5 and a groove 6-6 on the side.

[0043] The water inlet 6-2 is used for filling or pumping water to adjust the attitude of the float assembly, and a cover plate 4 is installed at the water inlet. The lifting lug 6-4 is the lifting point when lifting the float module 6.

[0044] The bollard 5 is installed on the float assembly and is used to tow the float assembly on the water.

[0045] The sludge discharge pipe support mechanism 3 is connected above the float module 6. Its upper part is used to support the sludge discharge pipe 1, and its lower part is connected to the float module 6 via a pin 7. The sludge discharge pipe support mechanism 3 is adjustable and can adapt to sludge discharge pipes 1 with different pipe diameters and wall thicknesses.

[0046] The sludge discharge pipe support mechanism 3 has a symmetrical structure and is installed above the floating module 6 to support the sludge discharge pipe 1. The sludge discharge pipe support mechanism 3 is adjustable and can adapt to sludge discharge pipes 1 with different pipe diameters and wall thicknesses.

[0047] The mud discharge pipe support mechanism 3 includes a support roller 3-1, a support telescopic rod 3-2, a locking nut 3-3, a clamping sleeve 3-4, a cylinder body 3-5 of the adjusting cylinder, a cylinder body support shaft 3-6, a hydraulic oil pipe quick connector 3-7, an adjusting device base 3-8, a support connecting rod 3-9, a support body 3-10, and a lower mounting seat 3-11 for the support body 3-10. The two ends of the support roller 3-1 are rotatably connected to one end of the support connecting rod 3-9, and the other end of the support connecting rod 3-9 is rotatably connected to the support body 3-10. The middle part of the cylinder body 3-5 of the adjusting cylinder is rotatably mounted on the adjusting device base 3-8 through the cylinder body support shaft 3-6. The adjusting device base 3-8 is fixedly mounted on the support body 3-10. The end of the support telescopic rod 3-2 of the adjusting cylinder is rotatably connected to the middle of the support roller 3-1. The hydraulic oil pipe quick connector 3-7 is located near both ends of the cylinder body 3-5 of the adjusting cylinder. The reasonable size design of each component makes it easier to adjust the support roller 3-1 over a wide range, thereby adapting to sludge discharge pipelines 1 with different diameters.

[0048] The support body 3-10 is the load-bearing body of the entire sludge discharge pipe support mechanism 3. It has a long rectangular structure and is made of steel plate. The bottom of the support body 3-10 is provided with a lower support mounting seat 3-11. The lower support mounting seat 3-11 is fitted onto the upper floating body mounting seat 6-3. The sludge discharge pipe support mechanism 3 and the floating body module 6 are connected and locked together by a pin 7.

[0049] The clamping sleeve 3-4 is a conical plastic body. One end is an annular shape and is connected to the cylinder body 3-5 of the adjusting cylinder. The other end is a conical plastic body, which is compressed under the turning of the locking nut 3-3, thereby clamping the support telescopic rod 3-2 and completing the mechanical locking.

[0050] The length of the support telescopic rod 3-2 can be adjusted according to the different pipe diameters and wall thicknesses of the sludge discharge pipeline 1 to adapt to different pipe diameters and wall thicknesses and play a supporting role.

[0051] The clamp 2 cooperates with the mud discharge pipe support mechanism 3 to clamp the mud discharge pipe 1 and then connects to the upper mounting seat 6-3 of the float.

[0052] The hydraulic pump station 8 is used to drive the adjusting cylinder of the mud discharge pipe support mechanism 3, thereby adjusting the distance between the two support rollers 3-1. The hydraulic pump station 8 includes both electric and manual systems. The electric system includes a motor pump group 8-1, a one-way valve 8-6, a safety valve 8-8, a speed regulating valve 8-9, a solenoid directional valve 8-5, and a hydraulic lock 8-10 connected in sequence. The manual system includes a hand-cranked pump group 8-2, a one-way valve 8-7, a manual directional valve 8-4, and a hydraulic lock 8-11 connected in sequence. Both the motor pump group 8-1 and the hand-cranked pump group 8-2 draw hydraulic oil from the hydraulic oil tank 8-3. Both the hydraulic lock 8-10 and the hydraulic lock 8-11 are connected to the hydraulic oil pipe quick connector 8-12.

[0053] The hydraulic hose quick connector consists of two parts, both of which are externally controlled check valves. One part is hydraulic hose quick connector 3-7, which is installed on the oil ports A and B of the adjusting cylinder body; the other part is hydraulic hose quick connector 8-12, which is installed on the outlet hose of the hydraulic pump station 8. In the disengaged state, both function as check valves, pressing the balls under the action of the spring to seal the oil and prevent oil leakage. In the connected state, the externally controlled pin simultaneously opens the balls of the check valves at both ends, thereby compressing the spring and creating a gap between the balls and the valve seats, thus opening the oil passage and completing the quick connection.

[0054] The specific implementation process of this invention is as follows: First, based on the diameter, length, and concentration of the medium inside the sludge discharge pipe 1, the weight and buoyancy requirements are calculated. Then, the number and combination of the floating body modules 6 are designed. The lower part of the floating body modules 6 is connected by the side bosses 6-5 and grooves 6-6, and the upper part is connected by bolts through the splicing plate 6-1 to form a floating body group.

[0055] Table 1. Weight of some types of sludge discharge pipelines and number of matching floating modules

[0056] Then, after the float modules 6 are connected to form the float group, the mud discharge pipe support mechanism 3 is installed above the float modules 6. The lower mounting seat 3-11 of the support body is fitted into the upper mounting seat 6-3 of the float body, and then it is connected and locked by the pin 7. Next, the position of the support roller 3-1 of the mud discharge pipe support mechanism 3 is adjusted, and the hydraulic oil quick connector 8-12 of the hose outlet of the hydraulic pump station 8 is connected to the hydraulic oil quick connector 3-7 of the mud discharge pipe support mechanism 3. After the connection is completed, the pressure oil output by the hydraulic pump station 8 enters the A port or B port of the cylinder body 3-5 of the regulating cylinder. The hydraulic pump station 8 has both electric and manual systems. When there is an external power supply, the motor pump unit 8-1 is started to draw hydraulic oil from the hydraulic oil tank 8-3. The oil then passes through the check valve 8-6, safety valve 8-8, speed control valve 8-9, solenoid directional valve 8-5, hydraulic lock 8-10, and hydraulic quick connector 8-12 in sequence, finally entering port A or B of the regulating cylinder 3-5 to drive the support telescopic rod 3-2 to extend or retract. When there is no external power supply, the hand pump unit 8-2 can be manually cranked to draw hydraulic oil from the hydraulic oil tank 8-3. The oil then passes through the check valve 8-7, manual directional valve 8-4, hydraulic lock 8-11, and hydraulic quick connector 8-12 in sequence, finally entering port A or B of the regulating cylinder 3-5 to drive the support telescopic rod 3-2 to extend or retract. The remote control adjustment cylinder adjusts the extension length of the support telescopic rod 3-2, thereby causing the support roller 3-1 to change position and adjust the distance between the two support rollers 3-1 to adapt to the outer wall of the mud discharge pipe 1.

[0057] Once the support roller 3-1 is in position, tighten the locking nut 3-3 to compress the clamping sleeve 3-4, thereby clamping the support telescopic rod 3-2 to complete the mechanical locking.

[0058] Finally, the sludge discharge pipeline 1 is hoisted onto the upper part of the sludge discharge pipe support mechanism 3, with the outer wall of the sludge discharge pipeline 1 tightly attached to the support roller 3-1 of the sludge discharge pipe support mechanism 3. Then, the clamp 2 is used to connect the sludge discharge pipeline 1 to the upper mounting seat 6-3 of the float module 6, so that the sludge discharge pipeline 1 is securely installed on the upper part of the float assembly. The bollard 5 is a detachable type and can be installed at an appropriate position in the assembled float assembly for towing the float assembly on water.

[0059] In the same project, if other types of dredging equipment also need to use this batch of floating body assemblies for their sludge discharge pipeline 1, and the diameter, wall thickness, and length of the sludge discharge pipeline 1 change, the floating body assembly can be locally spliced ​​or dismantled according to the new buoyancy requirements. At the same time, the position of the support roller 3-1 of the sludge discharge pipe support mechanism 3 can be adjusted to match the sludge discharge pipeline 1. This modular floating body device can be flexibly combined and makes full use of the floating body modules 6 already used on site. Only local modifications are needed to match different sludge discharge pipelines 1, eliminating the need for remote transportation of floating body modules 6 and improving construction efficiency.

[0060] When applied to actual construction and production, this invention will bring significant economic benefits and has great potential for widespread application.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
