Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of water treatment, and more particularly to an underwater dredging device and river dredging equipment using the device. Background Art
[0002] To carry out ecological dredging of relatively small rivers or urban waterways while avoiding the stirring of large amounts of sludge and the release of large amounts of suspended solids into the water, there is currently a type of mobile underwater device that transfers the extracted sludge to a hull on the water surface through a pipe, eliminating the need for drainage during the dredging process. However, if the riverbed sludge is deep or the water flow resistance is high, the underwater device can easily become stuck in the sludge, making it difficult or unstable to move, preventing the dredging work from being carried out smoothly. In addition, if the mobile device used is large, it is difficult to lift the underwater dredging device from the riverbed to the surface using only ropes. Utility Model Content

[0017] Figure 1 A schematic view of a river dredging device according to an embodiment of the present disclosure is shown, which includes an underwater dredging device 1 and a ship body 2, wherein the underwater dredging device includes a walking mechanism 11, a sludge pumping mechanism 12, a buoyancy adjusting mechanism 13, an auxiliary traction mechanism 14, and a pushing device 15.
[0018] The walking mechanism 11 can move according to a set program or the control of a user, so as to enable the underwater dredging device to move on the river bottom. The walking mechanism 11 can have an underwater motor, a transmission mechanism, and a moving part connected with the transmission mechanism. The moving part can be, for example, a track-type structure or a structure of a crawler wheel, so as to be suitable for moving in the bottom mud. The crawler wheel does not have a tire, and can include a plurality of rod members radiating outward from a shaft part and a rod-shaped tooth part provided at the end of each rod member. The rod-shaped tooth part of the crawler wheel can increase the grip force, facilitate walking, and at the same time avoid stirring too much bottom mud to affect the water quality and visibility of the water body.
[0019] The sludge suction mechanism 12 can include a sludge pump 121 and a pipe 122 to suck the river bottom sludge into the ship body on the water surface. The sludge suction mechanism 12 can further include a cover 123, which is provided with an inlet at the part adjacent to the sludge below and an outlet connected with the pipe above, and the cover is relatively airtight so that the incoming sludge is stirred in the cover to avoid secondary pollution to the water body.
[0020] The buoyancy adjusting mechanism 13 adjusts the buoyancy of the air bag to realize the operation state of the underwater dredging device rising to the water surface and diving to the river bottom. In addition, when the sludge is deep, the buoyancy of the air bag can be adjusted to improve the walking condition of the underwater dredging device and prevent it from sinking into the sludge. The buoyancy adjusting mechanism 13 includes an air bag 131, a fixed cylinder 132 and a pipeline system 133. The air bag 131 is fixed in the fixed cylinder 132, and the fixed cylinder 132 is fixed to the upper part of the underwater dredging device. In order to make the structure compact, the air bag 131 can be arranged around the sludge pump.
[0021] The pipeline system 133 includes a gas source power 1331, a pressure stabilizing valve 1332 connected to the gas source power 1331, automatic valves A, B, C and D, and a gas pipeline 1333 connected to the air bag 131. The parts in the pipeline system 133 are connected by gas pipelines. The gas source power 1331, the pressure stabilizing valve 1332, the automatic valves A-D can be arranged in the water equipment such as the ship body.
[0022] The gas inlet is connected to the automatic valve B, the gas source power 1331, the pressure stabilizing valve 1332 and the automatic valve D in sequence to fill the air bag with gas. The gas outlet is connected to the automatic valve C, the pressure stabilizing valve 1332, the gas source power 1331 and the automatic valve A in sequence to discharge the gas in the air bag. One end of the automatic valve A is connected at the node where the automatic valve B and the gas source power 1331 are connected, and the other end is connected at the node where the automatic valve D and the gas pipeline 1333 are connected. One end of the automatic valve C is connected at the node between the pressure stabilizing valve 1332 and the automatic valve D, and the other end is connected to the gas outlet.
[0023] The gas source power 1331 can adopt an air compressor, and the pressure stabilizing valve 1332 connected at the rear end of the gas source power 1331 can ensure the pressure in the air bag 131, and ensure the stability of the buoyancy of the air bag 131 and the pressure safety.
[0024] As shown in the figure, when the pipeline system 133 is in the air intake state, the automatic valve B and the automatic valve D are in the connected state, and the automatic valve A and the automatic valve C are disconnected. When the air source power 1331 is turned on, the air bag 131 will be inflated, that is, the pipeline is in the air intake state, as shown by arrow ① in the figure. Inflating the air bag can increase the buoyancy of the underwater dredging device, helping it to rise to the water surface. When the automatic valve B and the automatic valve D are disconnected, and the automatic valve A and the automatic valve C are in the connected state, the air source power 1331 is turned on, and the air bag 131 will be deflated, that is, the pipeline is in the exhaust state, as shown by arrow ② in the figure. The exhaust state deflates the air bag, thereby reducing the buoyancy of the underwater dredging device and causing it to dive to the river bottom. Through the above connection structure of multiple automatic valves, a single air compressor can be used to inflate and deflate the air bag, without the need for a separate exhaust device, thereby simplifying the device structure and saving costs. The pipeline system 133 can be fixed to the ship body 2 or fixed to other devices floating on the water surface.
[0025] The auxiliary traction mechanism 14 is used to assist the underwater dredging device in advancing and lifting upward, and can prevent the underwater dredging device from sinking in the bottom mud or walking difficultly in the case of more bottom mud. In addition, the auxiliary traction mechanism 14 can help the underwater dredging device 1 to rise to the water surface faster on the basis of the buoyancy adjusting mechanism 13. The auxiliary traction mechanism 14 includes a winch 141, and can further include a fixed pulley 142. The winch 141 can be a one-way winch, which includes a reduction motor 1411, an electromagnetic clutch 1412 and a winding drum 1413 connected in sequence. When the underwater dredging device runs on the river bottom, the electromagnetic clutch 1412 of the winch is optionally in the connected state, and the reduction motor 1411 operates to drive the winding drum 1413 to rotate, thereby pulling the traction rope to drive the underwater dredging device to advance. When the underwater dredging device finishes processing the corresponding river bottom, the winch can assist it to rise. When the underwater dredging device rises to the water surface to run, in order to make the underwater dredging device return to the working position, the traction rope needs to maintain a certain tension to avoid slackening, and at the same time reduce the drag resistance of the traction rope of the winding drum 1413. At this time, the electromagnetic clutch 1412 is in the disconnected state, and the reduction motor 1411 is in the disengaged state with the winding drum 1413. The fixed pulley 142 can be located at the bottom of the ship body, so as to run as close to the river bottom as possible when the underwater dredging device dives to the river bottom to run. Since the electromagnetic clutch is in the disconnected state when the underwater dredging device is away from the ship body, the winch can omit the brake part, thereby simplifying the structure of the winch.
[0026] The pushing device 15 is arranged at the rear end of the underwater dredging device, i.e. close to the ship body, and is used to return the underwater dredging device to the working position. The pushing device 15 may, for example, be a propeller type pushing device, a water jet type pushing device, etc. used for the ship body to move forward. When the underwater dredging device is to be moved away from the ship body or the winch, the electromagnetic clutch 1412 is disconnected, the reduction motor 1411 is in a disengaged state with the drum 1413, and the pushing device 15 is used to push the underwater dredging device away from the ship body or the winch. In this way, the underwater dredging device can be quickly moved to other areas for sediment treatment after the corresponding area is processed.
[0027] In the above embodiment, the auxiliary traction mechanism 14 is used in cooperation with the buoyancy adjusting mechanism 13 to achieve smooth walking of the underwater dredging device on the river bottom and quick rising to the water surface, and is used in cooperation with the pushing device to achieve quick movement of the underwater dredging device to the working position or the designated area. The underwater dredging device can be lifted by the buoyancy adjusting mechanism and the auxiliary traction mechanism after the sediment at the current walking position is completely processed, and can be quickly pushed to the next working position by the pushing device to clean the sediment. The underwater dredging device can be circulated around the position where the water surface equipment (such as the ship body) is located to perform the step.
[0028] The above description is only exemplary embodiments of the present disclosure, and is not intended to limit the protection scope of the present disclosure, and the protection scope of the present disclosure is determined by the appended claims.
