Description

Technical Field

[0001] This invention relates to the field of river dredging technology, and in particular to a floating device for river dredging and its method of use. Background Technology

[0002] River dredging is a fundamental project for maintaining river ecology and improving flood control and drainage capacity. Its main purpose is to remove accumulated silt from the riverbed, restore the normal cross-section of the river channel, and ensure smooth water flow. Existing technologies include the following aspects: 1. During the dry season, the river channel is partially blocked, the water is drained, and the silt is directly dredged out. This method is suitable for situations where the silt is deep and mechanical operations are difficult.

[0003] 2. Using excavators, dredging boats and other mechanical equipment to directly dredge or suck out silt from the riverbed is suitable for waterways with large silt accumulation and easy access by machinery.

[0004] 3. The silt is dispersed by a high-pressure water gun and then pumped away, which is suitable for narrow or sensitive water areas.

[0005] For example, patent CN211285757U discloses auxiliary equipment for floating dredging of river channels, including a hull. The hull has an upward-facing support surface in the middle of its chamber, which supports the dredging equipment. A fixing device for fixing the dredging equipment is provided on the support surface, and a positioning device for fixing the hull is arranged on the hull. The positioning device is movable with the hull. During the dredging process, the dredging equipment is driven into the chamber of the hull and fixed by the fixing device. Then, under the action of the bucket of the dredging equipment, the hull is towed into the section of the river that needs to be cleaned. At this time, the fixing device fixes the hull in this section of the river, thereby realizing the construction operation of the river silt. After the cleaning is completed, the dredging equipment can be transferred without the need for other transfer equipment, thereby effectively increasing the operability of the dredging equipment, reducing the dredging cost, and having strong practicality.

[0006] However, in existing technologies, dredging equipment is carried on ships, but in order to ensure the stability of the dredging equipment, the ships used are generally large and the applicable waterways are narrow. Summary of the Invention

[0007] The purpose of this invention is to provide a floating device for river dredging and its usage method, thereby solving the aforementioned technical problems.

[0008] To achieve the above objectives, the present invention provides a floating device for river dredging, including a shore guiding mechanism, a telescopic connecting mechanism, and a buoyancy mechanism. The buoyancy mechanism is connected to the telescopic connecting mechanism on both sides through an adjustment mechanism, and the telescopic connecting mechanism is connected to the shore guiding mechanism. The shore guiding mechanism includes a first guiding unit and a second guiding unit respectively disposed on both sides of the shore. The first guiding unit is provided with a filter press for sludge treatment, and the second guiding unit is provided with an overlapping plate for the passage of dredging equipment.

[0009] Preferably, the first guiding unit includes a first traveling chassis, which is set on a guide rail on the shore. A first mounting platform is connected to the first traveling chassis via a first lifting platform, and a filter press is mounted on the first mounting platform.

[0010] Preferably, the second guiding unit includes a second traveling chassis, which is set on a guide rail on the shore. A second mounting platform is connected to the second traveling chassis via a second lifting platform, and the middle of the second mounting platform is hinged to one end of the overlapping plate.

[0011] Preferably, the buoyancy mechanism includes a main float, with a multi-stage telescopic rod in the middle of the main float, and the telescopic ends of the multi-stage telescopic rod are connected to a secondary float.

[0012] Preferably, at least two adjustment slots are provided on both sides of the main float, and a U-shaped protective sleeve is fixed in the adjustment slot. At least one guide limiting bend is provided on the inner side of the U-shaped protective sleeve, and an installation block is provided on the guide limiting bend.

[0013] Preferably, the adjustment mechanism includes two adjusting springs arranged vertically, which are mounted on mounting plates at both ends of the adjustment sleeve and connected to the mounting block.

[0014] Preferably, the telescopic connection mechanism includes a drive screw and a telescopic sleeve sleeved on the drive screw. One end of the telescopic sleeve is hinged to the mounting block, and one end of the drive screw is connected to a telescopic drive motor via a universal joint.

[0015] Preferably, the top of the main float is provided with a protective surface, the protective surface is provided with a positioning and clamping mechanism, and the bottom of the main float is provided with a trigger switch for detecting the positioning of the radial float.

[0016] Preferably, the positioning and clamping mechanism includes a positioning drive motor, the output shaft of which is provided with a drive gear, and the first positioning rack and the second positioning rack both mesh with the drive gear. The first positioning rack and the second positioning rack are respectively provided on the guide strips on the protective surface, and the first positioning rack and the second positioning rack are respectively fixed with a first L-shaped positioning plate and a second L-shaped positioning plate.

[0017] Based on the above-mentioned method of using a floating device for river dredging, the specific steps are as follows: Step S1: Foundation fixing installation; According to the location of the construction section, guide rails are installed on the shore, and the first guide unit and the second guide unit are set on the guide rails; Step S2: Device assembly; The telescopic connecting mechanism on one side is assembled with the first guide unit, and then the telescopic connecting mechanism on one side, the buoyancy mechanism and the telescopic connecting mechanism on the other side are connected in sequence. The telescopic connecting mechanism on the other side is pulled to the second guide unit by the traction rope, and the telescopic connecting mechanism on the other side is assembled with the second guide unit. Step S3: Transfer of dredging equipment; The telescopic connecting mechanisms on both sides are retracted to their shortest length, so that the first guide unit, telescopic connecting mechanism, buoyancy mechanism and second guide unit are on the same horizontal plane. The multi-stage telescopic rod is activated so that the auxiliary float extends into the water surface to a set height. The overlapping plate is connected to the main float. The dredging equipment enters the main float in sequence through the second mounting platform and the overlapping plate, and the dredging equipment is positioned by the positioning clamping mechanism. Step S4: Dredging with dredging equipment; The telescopic connection mechanism adjusts the telescopic sleeve's extension and retraction degree through the telescopic drive motor. At the same time, the multi-stage telescopic rod returns to its initial position, causing the auxiliary float to contact and trigger the limit switch. This allows the main float and auxiliary float to jointly provide buoyancy, enabling the dredging equipment to perform dredging. The telescopic connection mechanism on both sides is adjusted according to the dredging progress to adjust the lateral position of the main float and auxiliary float. The longitudinal position of the first guide unit and the second guide unit is adjusted according to the dredging progress to adjust the longitudinal position of the main float and auxiliary float. Step S5: Sludge treatment; The dredging equipment grabs the silt and transfers it to a filter press for filtration and compression.

The two sides of the buoyancy mechanism 3 are connected to the telescopic connecting mechanism through the adjustment mechanism. The telescopic connecting mechanism is connected to the shore-based guiding mechanism. The guiding equipment is set on the shore, which greatly reduces the volume of the buoyancy device and has a wide range of applications.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] Example 1 like Figure 1 - Figure 2As shown, a floating device for river dredging includes a shore-based guiding mechanism 1, a telescopic connecting mechanism 2, and a buoyancy mechanism 3. The two sides of the buoyancy mechanism 3 are connected to the telescopic connecting mechanism 2 through an adjustment mechanism 4, and the telescopic connecting mechanism 2 is connected to the shore-based guiding mechanism 1.

[0025] The shore-based guiding mechanism 1 includes a first guiding unit 11 and a second guiding unit 12 respectively located on both sides of the shore. The first guiding unit 11 is equipped with a filter press 111 for sludge treatment. The first guiding unit 11 includes a first traveling chassis 112, which is mounted on a guide rail 5 on the shore. A first mounting platform 114 is connected to the first traveling chassis 112 via a first lifting platform 113, and the filter press 111 is mounted on the first mounting platform 114. The second guiding unit 12 includes a second traveling chassis 122, which is mounted on the guide rail 5 on the shore. A second mounting platform 124 is connected to the second traveling chassis 122 via a second lifting platform 123. The middle of the second mounting platform 124 is hinged to one end of the mounting platform 121. The longitudinal movement of the buoyancy mechanism 3 is achieved by driving the first traveling chassis 112 and the second traveling chassis 122.

[0026] The buoyancy mechanism 3 includes a main float 31, with a multi-stage telescopic rod 32 located in the middle of the main float 31. The telescopic ends of the multi-stage telescopic rod 32 are connected to auxiliary floats 33. A protective surface 313 is provided on the top of the main float 31 to protect its upper surface. A trigger switch is provided at the bottom of the main float 31 to detect the auxiliary float's position, preventing the internal motor from continuing to operate after the multi-stage telescopic rod 32 has retracted to its final position. The motor-driven multi-stage telescopic rod 32 is a common device in this field and will not be described in detail here. At least two adjustment slots 311 are provided on each side of the main float 31. A U-shaped protective sleeve 312 is fixed inside each adjustment slot 311. Two guide limiting bends are provided on the inner side of the U-shaped protective sleeve 312, such as... Figure 4 As shown, a mounting block 42 is provided on the guide limiting bend, allowing the mounting block 42 to move up and down along the guide limiting bend. Figure 3 As shown, the adjustment mechanism 4 includes two adjusting springs 41 arranged vertically. The two adjusting springs 41 are mounted on the mounting plates at both ends of the adjustment sleeve, and both adjusting springs 41 are connected to the mounting block 42.

[0027] The telescopic connection mechanism 2 includes a drive screw 21 and a telescopic sleeve 22 sleeved on the drive screw 21. One end of the telescopic sleeve 22 is hinged to the mounting block 42. One end of the drive screw 21 is connected to a telescopic drive motor 24 through a universal joint 23 to realize the rotational transmission with adjustable angle. Generally, the telescopic connection mechanism 2 on both sides has the same telescopic amount. However, when the river channel is wide, the telescopic connection mechanism 2 on both sides can have different telescopic amounts. The height can be adjusted by the first lifting platform 113 and the second lifting platform 123 to realize the adjustment of the lateral position.

[0028] Example 2 The difference between this embodiment and Embodiment 1 is that a positioning and clamping mechanism 6 is provided on the protective surface 313 for positioning and reinforcing the dredging equipment, such as... Figure 5 As shown, the positioning and clamping mechanism 6 includes a positioning drive motor 61, and the output shaft of the positioning drive motor 61 is provided with a drive gear 62. The first positioning rack 63 and the second positioning rack 64 are both meshed with the drive gear 62. The first positioning rack 63 and the second positioning rack 64 are respectively provided with guide strips 314 on the protective surface 313. The first positioning rack 63 and the second positioning rack 64 are respectively fixed with a first L-shaped positioning plate 65 and a second L-shaped positioning plate 66.

[0029] Based on the above-mentioned method of using a floating device for river dredging, the specific steps are as follows: Step S1: Foundation fixing installation; According to the location of the construction section, guide rail 5 is installed on the shore, and the first guide unit 11 and the second guide unit 12 are set on guide rail 5.

[0030] Step S2: Device assembly; The telescopic connecting mechanism 2 on one side is assembled with the first guide unit 11, and then the telescopic connecting mechanism 2 on one side, the buoyancy mechanism 3 and the telescopic connecting mechanism 2 on the other side are connected in sequence. The telescopic connecting mechanism 2 on the other side is pulled to the second guide unit 12 by the traction rope, and the telescopic connecting mechanism 2 on the other side is assembled with the second guide unit 12.

[0031] Step S3: Transfer of dredging equipment; The telescopic connecting mechanisms 2 on both sides are retracted to their shortest length, so that the first guide unit 11, telescopic connecting mechanism 2, buoyancy mechanism 3 and second guide unit 12 are on the same horizontal plane. The multi-stage telescopic rod 32 is activated so that the auxiliary float 33 extends into the water surface to a set height, and the overlapping plate 121 is overlapped with the main float 31. The dredging equipment enters the main float 31 in sequence through the second mounting platform 124 and the overlapping plate 121, and the dredging equipment is positioned by the positioning clamping mechanism 6.

[0032] Step S4: Dredging with dredging equipment; The telescopic connecting mechanism 2 adjusts the telescopic sleeve 22's extension degree via the telescopic drive motor 24. Simultaneously, the multi-stage telescopic rod 32 returns to its initial position, causing the main float 31 and the auxiliary float 33 to contact and trigger the limit switch. The multi-stage telescopic rod 32 stops retracting, allowing the main float 31 and the auxiliary float 33 to jointly provide buoyancy, enabling the dredging equipment to perform dredging. The lateral position of the main float 31 and the auxiliary float 33 is adjusted by adjusting the extension amount of the telescopic connecting mechanisms 2 on both sides according to the dredging progress. The longitudinal position of the main float 31 and the auxiliary float 33 is also adjusted by adjusting the longitudinal position of the first guide unit 11 and the second guide unit 12 according to the dredging progress.

[0033] Step S5: Sludge treatment; The dredging equipment grabs the sludge and transfers it to the filter press 111 for filtration and compression.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
