Description

Technical field:

[0001] The invention relates to a silt clearing system, and in particular to a decentralized energy-saving and environmentally friendly sediment clearing system. Background technology:

[0002] Due to natural or man-made reasons, a lot of silt is deposited at the bottom of rivers, lakes and reservoirs. In order to purify water quality, improve the environment and dredge waterways, people usually use dredging ships to clear silt, which is a water conservancy project. River siltation has increasingly affected the normal function of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal function of the river and promote the rapid and sustainable development of the economy and society, river dredging projects are carried out.

[0003] The existing dredging methods include using a water jetting river channel dredging ship for cleaning and a suction dredger for cleaning. The former uses the characteristics of the high flow rate of the river water, uses the power of the ship to drive the water pump, generates a high-pressure water flow into the water jet pipe, and shoots water through the water jet gun installed on the water jet pipe to stir the silt deposited on the riverbed into a turbid state, which flows away with the river water, thereby achieving the effect of dredging. However, this dredging method can only be used in river sections with a high flow rate, and the silt is eventually brought to the downstream of the river channel. In the river section with a relatively slow flow rate, it will still sink and accumulate, and it has not achieved thorough dredging. The dredging work is greatly restricted, and it is impossible to dredge the river channel, lakes and mudflats with a slow flow rate; the latter relies on the rotation, left and right swing of the auger at the front end of the auger bridge and the suction of the dredger pump to loosen the mud at a specified depth underwater and suck it to the designated mud unloading area. However, traditional cutter suction dredgers have a small cleaning area and need to be moved frequently. They are all powered by diesel, which consumes a lot of energy and causes certain pollution to rivers and lakes. In addition, the reamer-type mud dredging pumps installed on cutter suction dredgers have a weak conveying capacity. When dredging, areas close to the shore can be directly transported to designated areas on the shore, while areas far from the shore need to be ferried by transport ships, which increases the cost of dredging. In addition, the extra power consumed by transport ships will further pollute rivers and lakes. Summary of the invention:

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a decentralized energy-saving and environmentally friendly sediment desilting system.

[0005] The present invention is implemented by the following technical scheme: a decentralized energy-saving and environmentally friendly sediment desilting system, comprising a central floating platform and a plurality of decentralized floating platforms arranged around the central floating platform, wherein the central floating platform comprises a central platform body and a mud collection bin, a high-pressure mud pump and a mud delivery pipe arranged on the central platform body, wherein the inlet of the mud delivery pipe is placed at the inner bottom of the mud collection bin, and the mud delivery pipe is provided with the high-pressure mud pump;

[0006] Each of the dispersed floating platforms comprises a dispersed platform body and a reamer-type mud desilting pump disposed on the dispersed platform body;

[0007] Positioning devices are provided on both the central platform body and the dispersed platform body;

[0008] Each of the dispersed platform bodies is connected to the central platform body, and adjacent dispersed platform bodies are connected by a steel wire rope provided with a winch, and the winch is fixedly connected to the dispersed platform body or the central platform body; the outlet of each reamer-type mud dredging pump is connected to the mud collection bin through a silt conveying pipe.

[0009] Furthermore, the dispersed floating platform is a power platform, and a propeller is provided at the lower part of the dispersed platform body, and the propeller is rotatably connected to the dispersed platform body through a steering wheel.

[0010] Furthermore, the propeller is a ship electric propeller, and the ship electric propeller is mounted on the dispersion platform body.

[0011] Furthermore, the central floating platform is a power platform.

[0012] Furthermore, floating piers are provided on the mud conveying pipe and the silt conveying pipe.

[0013] Furthermore, a steel cable is provided on the mud conveying pipe, and the steel cable is fixed to the mud conveying pipe. One end of the steel cable is fixedly connected to the central platform body. When the dredging system is working, the two ends of the steel cable are respectively fixedly connected to the central platform body and the shore, which can further fix the mud conveying pipe and prevent it from being pulled.

[0014] Furthermore, the positioning device is a positioning anchor.

[0015] Furthermore, the positioning device is a positioning rod, and a positioning hole matching the positioning rod is vertically opened downward on the central platform body and / or the dispersed platform body, and the positioning rod is inserted into each of the positioning holes; a gear is also rotatably provided on the central platform body and / or the dispersed platform body, and a rack is fixed on the positioning rod, and the gear is meshed with the rack.

[0016] Furthermore, the positioning device also includes a motor arranged on the central platform body and / or the dispersed platform body, and each of the motors is connected to the corresponding gear transmission.

[0017] Advantages of the present invention:

[0018] 1. This dredging system increases the dredging area through the form of a central floating platform and a dispersed floating platform. There is no need to frequently move the entire system. Dredging can be achieved by simply using a winch or a propeller to drive the dispersed floating platform. Compared with the existing dredging method using a dredging ship, energy is saved.

[0019] 2. When this dredging system is used to dredge rivers and lakes, the central floating platform operates at a fixed point for a long time, so it can be powered by electricity from the shore, which is more environmentally friendly than the existing dredging boats that use diesel to provide power.

[0020] 3. This dredging system installs a reamer-type mud dredging pump with a weaker conveying capacity on the dispersed floating platform. The silt cleared by the dispersed floating platform is transported to the central floating platform, and then transported to the shore after secondary pressurization. It has a stronger processing capacity and solves the problem of increased dredging costs and pollution caused by the traditional cutter suction dredger relying on transport ships for dredging.

The central floating platform 1 comprises a central platform body 1.1 and a mud collecting bin 1.2, a high-pressure mud pump 1.3 and a mud delivery pipe 1.4 arranged on the central platform body 1.1. The central platform body 1.1 is an unpowered platform. The high-pressure mud pump 1.3 is placed at the inner bottom of the mud collecting bin 1.2. The inlet of the mud delivery pipe 1.4 is connected to the high-pressure mud pump 1.3. A steel cable 1.5 is fixedly provided on the mud delivery pipe 1.4. One end of the steel cable 1.5 is fixedly connected to the central platform body 1.1. When the dredging system is working, the other end of the steel cable 1.5 is fixedly connected to the shore, which can further fix the mud delivery pipe 1.4 to prevent it from being pulled.

[0031] Each dispersed floating platform 2 comprises a dispersed platform body 2.1 and a reamer type mud desilting pump 2.2 arranged on the dispersed platform body 2.1;

[0032] The central platform body 1.1 and the decentralized platform body 2.1 are provided with positioning devices 3. The positioning device 3 on the central platform body 1.1 is as follows: Figure 3 The positioning anchor 3.1 shown in the figure, the positioning device 3 on the dispersion platform body 2.1 is as follows Figure 4 and 5 As shown in the figure, a positioning hole matching the positioning rod 3.2 is vertically opened on the dispersion platform body 2.1, and a positioning rod 3.2 is inserted into each positioning hole; a gear 3.3 is also rotatably provided on the dispersion platform body 2.1, and the gear 3.3 is driven by a motor 3.5 fixed on the dispersion platform body. A rack 3.4 is provided on the positioning rod 3.2, and the gear 3.3 is meshed with the rack 3.4.

[0033] Each dispersed platform body 2.1 is connected to the central platform body 1.1, and adjacent dispersed platform bodies 2.1 are connected by a wire rope 2.4 provided with a winch 2.3. The winch 2.3 is fixedly arranged on the dispersed platform body 2.1 or the central platform body 1.1; the outlet of each reamer-type mud dredging pump 2.2 is connected to the mud collecting bin 1.2 through a silt conveying pipe 2.5.

[0034] In order to ensure the safety and stability of the mud conveying work, floating piers 4 are provided on the mud conveying pipe 1.4 and the silt conveying pipe 2.5.

[0035] Working principle:

[0036] When preparing for dredging, the dredging system uses a winch 2.3 to gather the dispersed floating platforms 2 to the opposite sides of the central floating platform 1, and then uses a tugboat to pull a dispersed floating platform 2, moves the dispersed floating platforms 2 and drives the central floating platform 1 forward. After the dredging system arrives at the dredging location, the positioning anchor 3 of the central floating platform 1 is dropped and fixed in position. The dispersed floating platforms 2 are dragged by the tugboat or driven by the electric propeller 2.6 to the sides of the central floating platform 1 and are positioned by the positioning device 3. Finally, the mud conveying pipe 1.4 is extended to the collection system on the shore, and the system is connected to electricity from the shore to provide power for dredging operations. In order to prevent the cable from being pulled after power is connected, the cable can be fixed on the steel cable 1.5.

[0037] When the dispersed floating platform 2 is positioned, the motor 3.5 drives the gear 3.3 to rotate, and through the meshing of the gear 3.3 and the rack 3.4, the positioning rod 3.2 is driven to move downward in the positioning hole until the bottom of the positioning rod 3.2 is inserted into the mud layer at the bottom of the river or lake, thereby achieving the positioning of the dispersed floating platform 2.

[0038] During dredging, the motor 3.5 on any dispersed floating platform 2 is reversed to drive the positioning rod 3.2 to rise, release the positioning of the dispersed floating platform 2, and repeatedly tighten and loosen the wire rope 2.4 between the dispersed floating platform 2 and two adjacent dispersed floating platforms 2 through the winch 2.3, so that the dispersed floating platform 2 performs a sweeping dredging operation on the water surface; the length of the wire rope 2.4 between the dispersed floating platform 2 and the central floating platform 1 is gradually controlled by the winch 2.3 to adjust the sweeping dredging radius of the dispersed floating platform 2.

[0039] During the dredging process, the swing dredging amplitude and dredging radius of a dispersed floating platform 2 can be controlled. After the silt within its coverage area is cleared, it is positioned, and then another adjacent dispersed floating platform 2 is started and controlled to dredge, and so on, to complete the dredging operation of all dispersed floating platforms 2; it is also possible to control the swing dredging amplitude of each dispersed floating platform 2 in turn, and after completing a round of dredging, adjust the dredging radius of each dispersed dredging platform 2, and then perform another round of dredging, and so on, to complete the dredging operation of all dispersed floating platforms 2.

[0040] The silt collected by the reamer type mud desilting pump 2.2 is transported to the mud collecting bin 1.2 through the silt conveying pipe 2.5, and finally transported to the shore by the high pressure mud pump 1.3 and the mud conveying pipe 1.4, so as to realize the cleaning and conveying operation of the silt.

The central platform body 1.1 is a ship-shaped power platform, and a high-power propeller (not shown in the figure) is arranged at the bottom thereof; the high-pressure mud pump 1.3 is placed at the inner bottom of the mud collecting bin 1.2, and the inlet of the mud delivery pipe 1.4 is connected to the high-pressure mud pump 1.3; a steel cable 1.5 is fixedly arranged on the mud delivery pipe 1.4, one end of the steel cable 1.5 is fixedly connected to the central platform body 1.1, and when the dredging system is working, the other end of the steel cable 1.5 is fixedly connected to the shore, which can further fix the mud delivery pipe 1.4 to prevent it from being pulled.

[0043] Each dispersed floating platform 2 comprises a dispersed platform body 2.1 and a reamer type mud desilting pump 2.2 arranged on the dispersed platform body 2.1;

[0044] The central platform body 1.1 and the decentralized platform body 2.1 are provided with positioning devices 3. The positioning device 3 on the central platform body 1.1 is as follows: Figure 3 The positioning anchor 3.1 shown in the figure, the positioning device 3 on the dispersion platform body 2.1 is as follows Figure 4 and 5 As shown in the figure, a positioning hole matching the positioning rod 3.2 is vertically opened on the dispersion platform body 2.1, and a positioning rod 3.2 is inserted into each positioning hole; a gear 3.3 is also rotatably provided on the dispersion platform body 2.1, and the gear 3.3 is driven by a motor 3.5 fixed on the dispersion platform body. A rack 3.4 is provided on the positioning rod 3.2, and the gear 3.3 is meshed with the rack 3.4.

[0045] Each dispersed platform body 2.1 is connected to the central platform body 1.1, and adjacent dispersed platform bodies 2.1 are connected by a wire rope 2.4 provided with a winch 2.3. The winch 2.3 is fixedly arranged on the dispersed platform body 2.1 or the central platform body 1.1; the outlet of each reamer-type mud dredging pump 2.2 is connected to the mud collecting bin 1.2 through a silt conveying pipe 2.5.

[0046] The dispersed floating platform 2 is a power platform, and a marine electric propeller 2.6 is provided on the side of the dispersed platform body. The marine electric propeller 2.6 is connected to the dispersed platform body. In this embodiment, the ET45L propeller produced by Taizhou Jusuo Industry and Trade Co., Ltd. is used. By hanging the suspension system of the electric propeller 2.6 on the side of the dispersed platform body 2.1, the control handle realizes the rotation direction of the propeller, and then controls the walking direction.

[0047] Floating piers 4 are provided on the mud conveying pipe 1.4 and the silt conveying pipe 2.5.

[0048] Working principle:

[0049] When preparing for dredging, the dredging system uses a winch 2.3 to gather the dispersed floating platforms 2 around the central floating platform 1, and then uses the power of the central floating platform 2 to move the dredging system. After arriving at the dredging location, the positioning device 3 of the central floating platform 1 is positioned, and the dispersed floating platforms 2 are dispersed to the sides of the central floating platform 1 under the push of the electric propeller 2.6 and positioned by the positioning device 3. Finally, the mud conveying pipe 1.4 is extended to the collection system on the shore, and the system is connected to electricity from the shore to provide power for dredging operations; in order to prevent the cable from being pulled after power is connected, the cable can be fixed on the steel cable 1.5, and the steel cable 1.5 is fixed to the mud conveying pipe 1.4.

[0051] During dredging, the motor 3.5 on any dispersed floating platform 2 is reversed to drive the positioning rod 3.2 to rise, release the positioning of the dispersed floating platform 2, and repeatedly tighten and loosen the wire rope 2.4 between the dispersed floating platform 2 and two adjacent dispersed floating platforms 2 through the winch 2.3, so that the dispersed floating platform 2 performs a sweeping dredging operation on the water surface; the length of the wire rope 2.4 between the dispersed floating platform 2 and the central floating platform 1 is gradually controlled by the winch 2.3 to adjust the sweeping dredging radius of the dispersed floating platform 2.

[0052] During the dredging process, the swing dredging amplitude and dredging radius of a dispersed floating platform 2 can be controlled. After the silt within its coverage area is cleared, it is positioned, and then another adjacent dispersed floating platform 2 is started and controlled to dredge, and so on, to complete the dredging operation of all dispersed floating platforms 2; it is also possible to control the swing dredging amplitude of each dispersed floating platform 2 in turn, and after completing a round of dredging, adjust the dredging radius of each dispersed dredging platform 2, and then perform another round of dredging, and so on, to complete the dredging operation of all dispersed floating platforms 2.

[0053] The dispersed floating platform 2 in the system can also be driven by the electric propeller 2.6 to perform sweeping and dredging operations. The electric propeller 2.6 is hung on the side of the dispersed platform body 2.1, and the hanging position can be adjusted as needed. During propulsion, the control handle adjusts the rotation direction of the propeller to control the walking direction.
