Description

Technical Field

[0001] The invention relates to the technical field of container cleaning, and in particular to a container cleaning system. Background Art

[0002] Traditional container interior cleaning mainly relies on pure manual flushing and a combination of manual and cleaning vehicles, which is not only costly but also inefficient. In addition, due to the different degrees of stains on different container walls, the focus of cleaning should also be different, and the residues after cleaning still need to be handled separately. Traditional container cleaning vehicles need auxiliary tracks for positioning when entering the container, which adds cumbersome steps and costs. In addition, the collection of crack information on the top wall of the container after cleaning and the collection and treatment of wastewater after cleaning all need to be done separately. Summary of the invention

[0003] The purpose of the present invention is to provide a container cleaning system to overcome the defects of the above-mentioned prior art, such as different cleaning degrees required for different wall surfaces of containers, separate treatment of residues after cleaning, the need for track-assisted positioning of container cleaning vehicles entering the container, collection and treatment of crack information on the top wall surface inside the container and waste water after cleaning, etc., to improve the cleaning efficiency, adapt to the different cleaning requirements of different wall surfaces of the container, reduce the power requirements and labor costs of the water pump; the treated waste water can be reused to avoid the waste of water resources; a simple structure is used for positioning without the need for track assistance; and the crack information on the top wall surface inside the container can be accurately collected.

[0004] The present invention provides a container cleaning system, comprising: a placement platform, a container, a cleaning vehicle, a cleaning platform, a water storage platform, and a water pumping device; the container is arranged on the placement platform, the placement platform is in contact with and connected to the cleaning platform, the cleaning vehicle is arranged on the cleaning platform, the cleaning platform is in contact with and connected to the water storage platform, and the water storage platform is in contact with and connected to the water pumping device;

[0005] The cleaning vehicle comprises: a box body and top and side cleaning water pipes, bottom cleaning water pipes, a waste dustpan, and a positioning device arranged on the box body; the top and side cleaning water pipes, bottom cleaning water pipes, and a waste dustpan are arranged at the front end of the box body, and a rolling brush is arranged at the side end of the box body;

[0006] The positioning device comprises: a hollow plate, a rolling bearing, a connecting rod, a universal wheel, a connecting plate, a high-pressure spring, and an infrared camera; a rolling bearing is arranged on the hollow plate, a connecting rod is arranged on the rolling bearing, a universal wheel is arranged on the connecting rod, a connecting plate is arranged at the side end of the box body, a high-pressure spring is arranged on the connecting plate, the high-pressure spring is connected to the connecting rod, and an infrared camera is arranged at the upper end of the box body;

[0007] The top surface of the washing table includes a plane and a third inclined surface, a box door and a water outlet are arranged on the side of the washing table, a notch is arranged on the third inclined surface, a first inclined surface and a second inclined surface are arranged inside the washing table, a solid-liquid separation plate is arranged on the first inclined surface, a liquid outlet is arranged on the solid-liquid separation plate, and the first inclined surface is connected to a water storage tank;

[0008] A first water inlet is provided on the side of the water storage platform, a second water outlet is provided at the rear of the water storage platform, a water reservoir is provided inside the water storage platform, and the first water inlet is connected to the first water outlet through a first elbow;

[0009] The front of the pumping device is provided with a third water outlet and a fourth water outlet. The third water outlet is connected to the top and side cleaning water pipes through a first hose, and the fourth water outlet is connected to the bottom cleaning water pipe through a second hose. The side of the pumping device is provided with a second water inlet, and the second water inlet is connected to the second water outlet through a second elbow. The top and side cleaning water pipes and the bottom cleaning water pipes are connected to the first hose and the second hose respectively, so that the cleaning vehicle can enter containers of different lengths. The pumping device is fixed and pumps water from the water storage platform through the second elbow. During the cleaning process, only the first hose and the second hose are extended horizontally to reduce the impact of the cleaning vehicle on the second hose and the second elbow during the forward movement.

[0010] Furthermore, a first fixing frame is arranged inside the box, and a rolling brush is arranged on the side end of the first fixing frame.

[0011] Furthermore, the hollow plate is arranged at the side end of the box body, and the hollow plate serves as a base for the positioning device.

[0012] Furthermore, a second fixing frame is provided at the upper end of the box body, and the infrared camera is provided on the second fixing frame.

[0013] Furthermore, the top and side cleaning water pipes and the bottom cleaning water pipes are both provided with fan-shaped nozzles.

[0014] Furthermore, the fan-shaped nozzle on the bottom cleaning water pipe forms an angle of 0 with the vertical direction. Therefore, the water jet generated by the fan-shaped nozzle has a pushing effect on the residue in the container during movement. When the cleaning vehicle reaches the bottom of the container, the residue is simultaneously pushed to the bottom of the container by the water jet, and the waste dustpan can collect the residue.

[0015] Furthermore, traditional container cleaning vehicles need auxiliary tracks for positioning when entering the container. Not only is the track installation cumbersome but it also greatly affects the container cleaning efficiency. In the present invention, after the cleaning vehicle enters the container, the universal wheels at both ends of the cleaning vehicle contact the walls on both sides of the container, and at the same time, the high-pressure springs are compressed to balance the forces at both ends of the box body, so that the box body is in the middle position of the container. The different curvatures of the high-pressure springs can adapt to the cleaning of containers of different widths, ensuring that the cleaning vehicle can be in the center position inside different containers.

[0016] Furthermore, after the container is cleaned, the waste dustpan is withdrawn together with the cleaning vehicle when it exits the container. The waste water and a small amount of residue not collected by the waste dustpan are carried out of the container by the rear baffle of the waste dustpan and flow to the third slope. On the third slope, the waste water and a small amount of residue enter the slot due to gravity, and pass through the first slope. The waste water and a small amount of residue are separated by the solid-liquid separation plate. The solid-liquid separation plate is provided with oil-absorbing material to further remove oil from the waste water. The separated waste water passes through the solid-liquid separation plate and flows through the second slope into the water storage tank. The water storage tank continues to precipitate the secondary residue. The waste water after the residue is precipitated finally flows to the water reservoir through the first outlet.

[0017] Furthermore, the top and side cleaning water pipes and the bottom cleaning water pipes are passed through the interior of the cleaning vehicle, and the apertures of the two water pipes are different to adapt to different cleaning requirements for different wall surfaces of the container.

[0018] Furthermore, since there is more dirt on the bottom of the container and less dirt on the top and sides, the top and side cleaning pipes and the bottom cleaning pipes can flush different surfaces of the container with different emphases. Rolling brushes are provided at both ends of the container to absorb water on both sides of the container after cleaning.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] (1) The container cleaning vehicle realizes fully automatic cleaning and waste collection of different wall surfaces of the container during the cleaning process. At the same time, the physical positioning device of the mobile cleaning vehicle realizes the function of keeping the mobile cleaning vehicle centered when entering the container, reducing the power requirements and labor costs of the water pump. The universal wheels at both ends of the cleaning vehicle are in contact with the walls of the container on both sides, and the compression spring makes the forces at both ends of the cleaning vehicle balanced, so that the cleaning vehicle is in the middle of the container; the top and side cleaning water pipes and the bottom cleaning water pipes run through the interior of the container cleaning vehicle, and the apertures of the two water pipes are different to adapt to the different cleaning requirements for different wall surfaces of the container.

[0021] (2) Two rotatable infrared cameras are installed on the top of the container cleaning vehicle. After the top of the container is cleaned, the image of the top of the container can be collected. The collected images can be subsequently processed to determine whether there are cracks on the top of the container and the location of the cracks. The accuracy of crack detection using the improved YOLOv5 is improved by about 20%.

[0022] (3) The cleaning table is divided into an inclined part and a flat part. The inclined part can send the wastewater and uncollected residues generated after container cleaning to the slot through water flow. After entering the cleaning table, the wastewater and residues are separated by a solid-liquid separation device. The residues inside the cleaning table are removed by opening the door on both sides of the cleaning table.

[0023] (4) The treated wastewater can be reused, avoiding the waste of water resources. The solid-liquid separation plate inside the cleaning station separates the small amount of uncollected residue from the wastewater generated after cleaning. The door on both sides of the cleaning box can be opened to facilitate the treatment of the residue. The fan-shaped nozzle on the bottom cleaning water pipe is at an angle of 45° to the vertical direction. Therefore, the water jet generated by the fan-shaped nozzle has a pushing effect on the residue in the container when moving. When the cleaning vehicle reaches the bottom of the container, the residue is also pushed to the bottom of the container by the water jet, and the waste dustpan can collect the residue.

[0024] (5) Use a simple structure for positioning without the need for track assistance. After the cleaning vehicle enters the container, the universal wheels at both ends of the cleaning vehicle contact the walls of the container on both sides, and at the same time compress the high-pressure spring to balance the forces at both ends of the container, so that the container is in the middle of the container. The different bends of the high-pressure spring can adapt to the cleaning of containers of different widths, ensuring that the cleaning vehicle can be in the center of different containers.

The pumping device 6 is provided with a second water inlet 603 on the side. The second water inlet 603 is connected to the second water outlet 502 through the second elbow G4. The top and side cleaning water pipe 302 and the bottom cleaning water pipe 303 are connected to the first hose G2 and the second hose G3 respectively, so that the cleaning vehicle 3 can enter containers of different lengths.

During the cleaning process, only the first hose G2 and the second hose G3 are extended horizontally to reduce the impact of the cleaning vehicle 3 on the second hose G3 and the second elbow G4 during the forward movement.

[0048] In a specific implementation, a first fixing frame 306 is disposed inside the box body 301 , and a rolling brush 307 is disposed at a side end of the first fixing frame 306 .

[0051] In a specific implementation, the top and side cleaning water pipes 302 and the bottom cleaning water pipes 303 are both provided with fan-shaped nozzles 304 .

[0052] In a specific embodiment, the fan-shaped nozzle 304 on the bottom cleaning water pipe 303 forms an angle of 45° with the vertical direction. Therefore, the water jet generated by the fan-shaped nozzle 304 has a pushing effect on the residue in the container 2 during movement. When the cleaning vehicle 3 reaches the bottom of the container 2, the residue is simultaneously pushed to the bottom of the container 2 by the water jet, and the waste dustpan 305 can collect the residue.

[0053] In a specific embodiment, a traditional container cleaning vehicle needs an auxiliary track for positioning when entering a container. Not only is the track installation cumbersome, but it also greatly affects the container cleaning efficiency. In the present invention, after the cleaning vehicle 3 enters the container 2, the universal wheels 311 at both ends of the cleaning vehicle 3 contact the walls of the container 2 on both sides, and at the same time, the high-pressure spring 313 is compressed to balance the forces at both ends of the box body 301, so that the box body 301 is in the middle position of the container 2.

[0054] In a specific embodiment, after the cleaning of the container 2 is completed, the waste dustpan 305 is withdrawn together with the cleaning vehicle 3 when it exits the container 2. The waste water and a small amount of residue not collected by the waste dustpan 305 are carried out of the container by the rear baffle of the waste dustpan 305 and flow to the third slope 402. On the third slope 402, the waste water and a small amount of residue enter the slot 404 due to gravity, and pass through the first slope 408. The waste water and a small amount of residue are separated by the solid-liquid separation plate 406. The solid-liquid separation plate 406 is provided with oil absorbing material to further remove oil from the waste water. The separated waste water passes through the solid-liquid separation plate 406, flows through the second slope 409, and then enters the water storage tank 410. The water storage tank 410 continues to precipitate the secondary residue. The waste water after the residue is precipitated finally flows to the water reservoir through the first water outlet 405.

[0055] In a specific embodiment, the top and side surface cleaning water pipes 302 and the bottom surface cleaning water pipes 303 are penetrated inside the cleaning vehicle 3 , and the apertures of the two water pipes are different to adapt to different cleaning requirements for different wall surfaces of the container 2 .

[0056] In a specific embodiment, since there is more dirt on the bottom surface of the container 2 and less dirt on the top and sides, the top and side cleaning water pipes 302 and the bottom cleaning water pipes 303 can wash different surfaces of the container with different emphases. Rolling brushes 307 are provided at both ends of the box body 301, which can absorb water on both sides of the container 2 after cleaning.
