Description

Technical Field

[0001] This invention relates to the field of water conservancy dredging equipment technology, and in particular to an adaptive amphibious dredging vehicle. Background Technology

[0002] Dredging and clearing of water bodies have the effects of preventing floods, increasing water storage capacity, and improving water body maintenance capabilities. They are of great significance to people's livelihood and ecological protection.

[0003] Currently, the commonly used water dredging methods mainly employ excavation and pump suction methods. Excavation typically involves draining the water or excavating on water. Draining requires first draining the water body and then using an excavator for dredging, which is not only energy-intensive but also severely damages the water body, making it only suitable for small bodies of water. On-water excavation requires bucket dredgers for dredging, such as the dredging vessel with patent number CN2038083U. This dredging vessel not only causes significant disturbance to the water body but also severely damages the aquatic ecosystem. Pump suction relies on shipboard equipment, such as the sludge cleaning vessel with patent number CN214097780U. This vessel is equipped with a sludge pump, which agitates the sludge at the pump inlet to dilute it before pumping it into the hull. This method is not very adaptable to the underwater geographical environment. It cannot operate in shallow or deep water areas due to grounding issues and the limited length of the pump. Furthermore, it is difficult to accurately control the pump's attitude to match the underwater environment, resulting in significant water disturbance and incomplete dredging.

[0004] Therefore, how to design a dredging device that can reduce water disturbance, protect aquatic ecosystems, and improve dredging efficiency is a problem that urgently needs to be solved by those skilled in the art.

[0005] Content of this invention

[0006] This invention provides an adaptive amphibious dredging vehicle that solves the technical problems of existing dredging equipment causing large water disturbances, damaging the aquatic ecosystem, and having poor dredging effects.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an adaptive amphibious dredging vehicle, comprising: a frame, a floating mechanism for driving the frame to rise and fall in water, a walking mechanism, a pump port posture adjustment mechanism, a dredging mechanism, and a terrain detection mechanism.

[0008] The vehicle frame includes a mounting frame and a movable frame, the movable frame being slidably connected to the mounting frame; there are two floating mechanisms, each fixed to the lower part of both sides of the mounting frame in the direction of travel; there are two traveling mechanisms, each mounted on one of the two floating mechanisms.

[0009] The pump port position adjustment mechanism includes a lifting cylinder, a swing cylinder, and a swing bracket. The lifting cylinder is fixed on the mounting frame and its piston rod is connected to the movable frame in a transmission manner. The swing cylinder is fixed on the movable frame. The swing bracket is located inside the mounting frame and is fixed on the output shaft of the swing cylinder.

[0010] The dredging mechanism is located inside the mounting frame and fixed to the swing bracket; the terrain detection mechanism is fixed to the front end of the mounting frame in the direction of travel.

[0011] The beneficial effects of this invention are: it changes the traditional method of dredging silt from the bottom of the water. First, a floating mechanism is used to submerge the dredging trolley to the bottom of the water body. Then, a terrain detection mechanism is used to explore the distribution of silt on the bottom of the water body. Since the lifting cylinder and swing cylinder of the adjustment mechanism can drive the swing support to move up and down and swing, it can drive the dredging mechanism to move up and down and swing, thereby adjusting the angle of the sludge inlet of the dredging mechanism and its position in the water body, reducing water disturbance, and improving the dredging effect and efficiency of the silt at the bottom of the water body.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the mounting frame includes a lower horizontal frame, an upper horizontal frame, and multiple vertical rods. The top and bottom ends of the multiple vertical rods are respectively vertically fixed to the edges of the upper horizontal frame and the lower horizontal frame. Two floating mechanisms are respectively installed on both sides of the lower horizontal frame in the direction of travel. There are two lifting cylinders, which are respectively fixed on both sides of the upper horizontal frame in the direction of travel. The terrain detection mechanism is fixed to the front end of the upper horizontal frame in the direction of travel. The swing bracket and the dredging mechanism are both located between the multiple vertical rods.

[0014] Furthermore, the movable frame consists of two sets, each including a sliding sleeve and a movable frame. The two sets of sliding sleeves are respectively slidably mounted on the vertical rods on both sides of the lower horizontal frame in the direction of travel. The movable frames are respectively fixed on the two sets of sliding sleeves. The piston rods of the two lifting cylinders are respectively fixed to the two movable frames. The swing cylinder is fixed on one of the movable frames.

[0015] The further beneficial effects of the above are: by using the sliding sleeve to slide on the vertical rod, when the piston rod of the lifting cylinder extends or retracts, the sliding sleeve and the moving frame can be easily driven to move up and down, thereby pushing the swing cylinder and the swing bracket to move up and down. Since the dredging mechanism is fixed on the swing bracket, it can also drive the dredging mechanism to move up and down at the same time.

[0016] Furthermore, the pump port position adjustment mechanism also includes a fixing block, which is fixed to another of the movable frames; one side of the swing bracket is fixed to the output shaft of the swing cylinder, and the other side is rotatably connected to the fixing block via a rotating shaft.

[0017] The further beneficial effect of adopting the above is that by fixing the fixed block and the swing cylinder to the two moving frames respectively, the stability of the swing bracket installation can be improved.

[0018] Furthermore, both of the aforementioned floating mechanisms include a buoyancy chamber, a partition, and a high-pressure gas tank equipped with an electromagnetic valve. The partition is vertically installed inside the buoyancy chamber and divides the interior of the buoyancy chamber into an independent water storage chamber and a gas tank mounting cavity. The partition has a vent hole connecting the water storage chamber and the gas tank mounting cavity. The outer wall of the buoyancy chamber corresponding to the water storage chamber has a water passage hole and a vent hole. Electromagnetic valves are installed at the vent hole, the vent hole, and the water passage hole. The high-pressure gas tank is installed in the gas tank mounting cavity, and its outlet is connected to the vent hole.

[0019] The further beneficial effects of the above-mentioned method are as follows: By installing a high-pressure air tank in the air tank installation cavity, when floating, the solenoid valves at the vent and water inlet are opened, and the solenoid valve at the exhaust port is closed. The gas generated by the high-pressure air tank enters the water storage chamber through the vent and discharges the liquid in the water storage chamber from the water inlet, raising the dredging trolley. When diving, the solenoid valve at the vent is closed, and the solenoid valves at the water inlet and exhaust port are opened. At this time, the water flow enters the buoyancy chamber under the water pressure, squeezing the gas in the water storage chamber and discharging it from the exhaust port, causing the dredging trolley to sink.

[0020] Furthermore, the outer wall of the buoyancy chamber corresponding to the gas tank mounting cavity has an air inlet, and an electromagnetic valve is installed at the air inlet.

[0021] The further beneficial effect of adopting the above is that it facilitates the inflation of the high-pressure gas tank in the gas tank installation cavity when the dredging trolley is not in operation.

[0022] Furthermore, each of the two traveling mechanisms includes a drive hydraulic motor, a traveling reducer, a drive sprocket, a driven sprocket, a track, and multiple scrapers. The two drive hydraulic motors are respectively fixed at one end of the two buoyancy chambers in the forward direction. The two traveling reducers are respectively driven and connected to the output shafts of the two drive hydraulic motors. The two drive sprockets are respectively driven and connected to the output shafts of the two traveling drive reducers. The two driven sprockets are respectively rotatably connected to the other end of the two buoyancy chambers in the forward direction via brackets. The two tracks are respectively fitted onto the outer sides of the two buoyancy chambers, and the two tracks are respectively driven and connected to the drive sprocket and the driven sprocket on one side. The multiple scrapers are respectively fixed at intervals to the outer walls of the two tracks along the forward direction of the two tracks.

[0023] The further beneficial effect of adopting the above is that by fixing multiple scrapers at intervals on the tracks, it can move on land and swim in water.

[0024] Furthermore, all of the aforementioned scrapers are made of rubber.

[0025] Furthermore, it also includes multiple lifting rings, which are fixed at intervals to the top of the upper horizontal frame.

[0026] The further beneficial effect of adopting the above is that the lifting ring can be connected to the crane on the shore, which makes it easier to quickly lift the dredging trolley and improve its floating and rising efficiency.

[0027] Furthermore, the dredging mechanism includes a slurry pump, a slurry hydraulic motor, and a delivery hose. The slurry pump is located inside the mounting frame and fixed on the swing bracket. The slurry pump has a sludge inlet at its bottom end and a sludge outlet on its rear side in the direction of travel. The slurry hydraulic motor is fixed on the slurry pump. One end of the delivery hose is fixed and connected to the sludge outlet of the slurry pump.

[0028] The further beneficial effect of adopting the above is that by fixing one end of the delivery hose and connecting it to the sludge outlet of the slurry pump, it is convenient to directly discharge sludge from the water body, thereby improving the dredging speed.

[0029] Furthermore, the terrain detection mechanism is a miniature sonar probe or a miniature laser 3D scanner. Attached Figure Description
