Description

Technical Field

[0001] This invention belongs to the field of construction vessel technology, and in particular relates to a drainage ditch cleaning vessel. Background Technology

[0002] Environmental protection construction projects and dredging projects often involve the cleaning of drainage ditches. Drainage ditches are channels used for drainage, removing rainwater and other surface water, and guiding it to rivers and lakes. Over time, silt accumulates in drainage ditches, and garbage, aquatic plants, and other debris float on the surface. These factors reduce the drainage capacity of the ditches, necessitating regular cleaning. Cleaning work includes removing surface debris and vegetation, and appropriately dredging the bottom of the ditches to resolve blockages and expand the channel's capacity.

[0003] Unlike construction in open water, drainage ditches are typically narrow, making it difficult for large cleaning vessels to enter and operate. Therefore, there is a need to develop a smaller cleaning vessel system to meet construction requirements. On the other hand, existing cleaning facilities usually only have the ability to clean the surface of the water and do not have the ability to clean the silt at the bottom of the ditch. The dredging of the bottom of drainage ditches still uses equipment such as long-arm excavators, which has low cleaning efficiency and high construction costs.

[0004] In summary, a new type of drainage ditch cleaning vessel needs to be developed and designed to solve the aforementioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage canal cleaning vessel, which is an unmanned, miniaturized cleaning vessel used in drainage canal cleaning projects, and has the ability to clean the water surface and dredge the bottom of the canal.

The cleaning vessel is equipped with a cutting device at the front, enabling it to remove debris, especially floating weeds, during movement, preventing obstruction. A lifting conveyor belt and a tossing device at the front collect and clean floating debris such as garbage along the movement path, placing the cleaned debris into a collection box. A filter-type sludge removal device and two sets of lifting pipes and extraction devices at the rear of the vessel enable the breaking down and extraction of silt from the bottom of the water. The extracted silt chunks undergo mud-water separation within the filter-type sludge removal device before being transferred to another filter-type sludge removal device. Therefore, the cleaning vessel of this invention has the ability to clean both the water surface and the bottom of the canal. Attached Figure Description

[0022] Please see Figure 1 and Figure 2This invention provides a drainage ditch cleaning vessel, comprising a hull 1, with a notch at the front of the hull 1. An inclined lifting conveyor belt 3, driven by a lifting drive motor 7, is installed within the notch. A gantry frame 4 is installed above the notch, and two actuating devices 6 are installed on the gantry frame 4. A detachable and transferable collection box 2 is installed in the middle of the hull 1, behind the lifting conveyor belt 3.

[0023] During the forward movement, the two left and right actuating devices 6 move floating objects such as garbage on the water surface to the front of the lifting conveyor belt 3. As the lifting conveyor belt 3 moves, it lifts and moves the aforementioned debris, and finally the debris is sent into the collection box 2.

[0024] In this embodiment, the actuating device 6 includes an actuating motor mounted and fixed on the gantry frame 4. An actuating shaft is mounted at the lower end of the output shaft of the actuating motor, and actuating blades are mounted on the actuating shaft. The actuating shafts of the left and right actuating devices 4 rotate in opposite directions. Specifically, as follows... Figure 1 As shown, during operation, the actuating shaft of the upper actuating device 6 rotates counterclockwise, and the actuating shaft of the lower actuating device 6 rotates clockwise. In this way, during operation, the two actuating devices 6 transfer the floating objects on the water surface to the middle, which is beneficial for the concentration of the floating objects and their transfer to the lifting conveyor belt 3.

[0025] In this embodiment, a groove for accommodating the bottom of the collection box 2 is provided in the middle of the hull 1, and a locking mechanism is provided between the collection box 2 and the hull 1. A hanging connection hole is provided on the wall of the collection box 2. The locking mechanism can be a pressure plate, and a fixing plate is provided on the bottom side of the outer wall of the collection box 2. When the collection box 2 is placed in the groove in the middle of the hull 1, the pressure plate holds it against the fixing plate to ensure the stability of the collection box 2. When the collection box 2 is full, the cleaning vessel docks, and a shore crane is used to lift and transfer the collection box 2. After the contents of the collection box 2 are emptied onto the truck bed of a transport vehicle, the collection box 2 is then transferred to the hull 1.

[0026] A cutting device 5 driven by a cutting drive motor 11 is also installed at the bottom front of the hull 1. The cutting device 5 is used to cut debris, especially floating water plants, on the movement path to avoid obstruction of the cleaning vessel.

[0027] In this embodiment, the cutting device 5 includes a fixed cutting blade installed at the front of the hull 1 and a movable cutting blade driven by a cutting drive motor 11 to move back and forth. Both the fixed cutting blade and the movable cutting blade have cutting teeth at their front ends. When running, the movable cutting blade performs a reciprocating cutting action, and the interlaced cutting teeth generate a shearing effect.

[0028] A filter-type sludge removal device 8 is installed behind the collection box 2. A longitudinal through hole is provided on both sides of the rear of the hull 1, and a lifting pipe 10 is provided in the through hole. An extraction device 9 is installed at the lower end of the lifting pipe 10, and a bend is installed at the upper end of the lifting pipe 10. The bend sends the sludge extracted by the extraction device 9 and lifted by the lifting pipe 10 into the top opening of the filter-type sludge removal device 8. The filter-type sludge removal device 8 transfers the filtered and trapped debris into the collection box 2.

[0029] Since the lifting pipe 10 is located in the through hole on the rear side of the hull 1, the lifting pipe 10 can rise or fall within the through hole. Therefore, during the operation of the cleaning vessel in this drainage channel, the extraction device 9 rests on the mud surface at the bottom of the water. As the cleaning vessel moves, the extraction device 9 can rise and fall with the changes in the height of the mud surface at the bottom of the water, that is, it can track the terrain of the mud surface at the bottom of the water.

[0030] Please see Figure 3 and Figure 4 It can be seen that:

[0031] The filter-type sludge removal device 8 includes a support body 8-2 and a top frame 8-6 located above the support body 8-2. Multiple lower springs 8-3 are installed between the bottom of the support body 8-2 and the hull 1, and multiple upper springs 8-1 are installed between the support body 8-2 and the top frame 8-6.

[0032] A filter grille 8-5 is provided inside the top frame 8-6. A front electric actuator 8-7 is installed between the front of the support body 8-2 and the front of the filter grille 8-5. A rear electric actuator 8-8 is installed between the rear of the support body 8-2 and the rear of the filter grille 8-5. A conical bottom opening 8-9 is installed at the bottom of the top frame 8-6. Specifically, windows are provided on both the front and rear walls of the conical bottom opening 8-9, and the front electric actuator 8-7 and the rear electric actuator 8-8 are located in the front and rear windows, respectively.

[0033] The front electric actuator 8-7 and the rear electric actuator 8-8 are used to control the height and tilt of the filter grid 8-5. During the filtration stage, the filter grid 8-5 descends to... Figure 3 As shown in the low position, when the trapped material is transferred into the collection box 2, the telescopic rods of the front electric push rod 8-7 and the rear electric push rod 8-8 extend upwards. However, the piston rod of the front electric push rod 8-7 extends less than the piston rod of the rear electric push rod 8-8. Finally, the front edge of the filter grid 8-5 is approximately at the same height as the front of the top frame 8-6, while the rear edge of the filter grid 8-5 is higher than the rear of the top frame 8-6, forming a slope, and the trapped material gradually transfers into the collection box 2.

[0034] In this embodiment, vibration motors 8-4 are installed on both sides of the support 8-2 and the top frame 8-6. The vibration motors 8-4 provide a certain vibration effect to improve efficiency in the filtration and transfer stages.

[0035] In this embodiment, a notch is provided at the rear of the hull 1, and the conical bottom opening 8-9 of the filter-type sludge removal device 8 is located above the notch. The filtered tailwater is discharged through the conical bottom opening 8-9 and then falls back into the water through the notch at the rear.

[0036] In this embodiment, as shown Figure 3 As shown, there are also multiple guide ribs on the surface of the filter grid 8-5. When the filter grid 8-5 rises and forms an inclined surface, each guide rib helps the intercepted material to move into the collection box 2.

[0037] Please see Figure 5 It can be seen that:

[0038] The extraction device 9 includes a base 9-2, and a box 9-6 with a cover 9-4 is installed below the base 9-2. An electric push rod 9-3 for opening and closing the door is installed between the cover 9-4 and the box 9-6. The opening and closing of the cover 9-4 is controlled by the electric push rod 9-3.

[0039] A conveying auger 9-5 driven by an auger motor (not shown in the figure) is installed inside the housing 9-6. A mud pump 9-1 is installed inside the base 9-2. The inlet of the mud pump 9-1 is connected to the inner cavity of the housing 9-6, and the outlet of the mud pump 9-1 is connected to the lower end of the lifting pipe 10. During operation, the door opening and closing electric push rod 9-3 opens the housing cover 9-4, and the conveying auger 9-5 and mud pump 9-1 operate, creating a negative pressure environment inside the housing 9-6. The silt at the bottom of the drainage ditch moves towards the housing, and the conveying auger 9-5 provides movement and agitation to the silt. Finally, the mud-water mixture is lifted by the lifting pipe 10 and sent through a bend into the top opening of the filter-type sludge removal device 8.

[0040] When the cleaning vessel is moving, the extraction device 9 rests on the mud surface at the bottom of the water and tracks the undulations of the mud surface. At the same time, the lifting pipe 10 rises and falls within the through hole. The height of the bend will change, but it will not affect the injection of the mud-water mixture into the filter-type sludge removal device 8.

[0041] A shipboard controller 13 is installed at the front of the hull 1, a lighting lamp 12 is installed on the gantry 4, and a storage battery is installed inside the hull 1 to provide the electrical energy required for the operation of the cleaning vessel. The lighting lamp 12 is used to provide forward lighting in low light conditions, and the shipboard controller 13 is used to provide on-site control functions.

[0042] The travel motor, toggle motor, cutting drive motor 11, lifting drive motor 7, front electric push rod 8-7 and rear electric push rod 8-8, vibration motor 8-4, mud pump 9-1, auger motor, door opening and closing electric push rod 9-3, and lighting 12 are all connected to the shipboard controller 13. The shipboard controller 13 includes a controller module and a wireless communication module. Onshore operators send commands to the shipboard controller 13 via a handheld wireless remote control, and the shipboard controller 13 controls the start or stop of the various devices on the cleaning vessel.

[0043] Operating method:

[0044] The cleaning vessel is transferred to the drainage ditch by towing or hoisting and floats on the water surface. The two extraction devices 9 are placed on the mud surface at the bottom of the water. The shore operator sends instructions to the ship's controller 13 through a wireless remote control to start the motor, the cutting drive motor 11, and the lifting drive motor 7. The door opening and closing electric push rod 9-3 opens the box door 9-4, and the auger motor and mud pump 9-1 run. The operator controls the start, stop, forward and reverse rotation of the travel motor and controls the movement of the cleaning vessel in the drainage ditch.

[0045] During the movement of the cleaning vessel, the agitator 6 moves the floating debris along the path, while the lifting conveyor belt 3 lifts and transports the received debris. When the debris reaches a high position, it enters the collection box 2. The extraction device 9 extracts the mud from the bottom of the water, and the mud-water mixture is injected into the filter-type dredging device 8. Inside the filter-type dredging device 8, the mud-water mixture is filtered. After passing through the filter grid 8-5, the mud-water is discharged through the conical bottom opening 8-9 and falls back into the water below, allowing the drainage channel to flow. The water will carry away the amount of mud contained in this muddy water. The lumpy silt and some lumpy debris are intercepted by the filter screen 8-5. When it is observed that a certain amount of intercepted material has accumulated on the filter screen 8-5, operate the front electric push rod 8-7 and the rear electric push rod 8-8 to lift the filter screen 8-5 to a high position and form a slope that is lower in the front and higher in the back. With the vibration action of the vibration motor 8-4, the intercepted material is gradually transferred into the collection box 2. After the transfer, operate the front electric push rod 8-7 and the rear electric push rod 8-8 to reset.

[0046] When collection box 2 is full, control the cleaning vessel to move to shore, use a shore crane to lift collection box 2 and dump the contents into the truck bed of the transport vehicle, then reload collection box 2 and continue the aforementioned cleaning operation.
