Description

Technical Field

[0001] This invention relates to the field of container cleaning technology, and in particular to a container cleaning system. Background Technology

[0002] Traditional container interior cleaning mainly relies on manual rinsing or a combination of manual and cleaning truck cleaning, which is not only costly but also inefficient. In addition, the different degrees of dirt on different container walls require different cleaning focuses, and the residue after cleaning still needs to be handled separately. Traditional container cleaning trucks need auxiliary tracks for positioning when entering the container, which increases the cumbersome steps and costs. Furthermore, the collection of information on cracks in the container's interior top wall after cleaning, as well as the collection and treatment of wastewater after cleaning, all need to be carried out separately. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the varying cleaning requirements for different container walls, the need for separate handling of cleaning residue, the need for track-assisted positioning for container cleaning vehicles to enter the container, the need for information on cracks in the container's internal top wall, and the collection and treatment of wastewater after cleaning. This invention provides a container cleaning system that improves cleaning efficiency, adapts to the different cleaning requirements of different container walls, reduces the power requirements of water pumps and labor costs, allows for the reuse of treated wastewater, avoids water waste, uses a simple structure for positioning without track assistance, and can accurately collect information on cracks in the container's internal top wall.

[0004] This invention provides a container cleaning system, comprising: a placement platform, a container, a cleaning vehicle, a cleaning platform, a water storage platform, and a pumping device; the container is placed on the placement platform, the placement platform is in contact with the cleaning platform, the cleaning vehicle is installed on the cleaning platform, the cleaning platform is in contact with the water storage platform, and the water storage platform is in contact with the pumping device. The cleaning vehicle includes: a box body and a top and side cleaning water pipe, a bottom cleaning water pipe, a waste scoop, and a positioning device disposed on the box body; the top and side cleaning water pipe, the bottom cleaning water pipe, and the waste scoop are disposed at the front end of the box body, and a rolling brush is disposed at the side end of the box body; The positioning device includes: a hollow plate, a rolling bearing, a connecting rod, a caster wheel, a connecting plate, a high-pressure spring, and an infrared camera; the hollow plate is provided with a rolling bearing, the rolling bearing is provided with a connecting rod, the connecting rod is provided with a caster wheel, the side end of the box is provided with a connecting plate, the connecting plate is provided with a high-pressure spring, the high-pressure spring is connected to the connecting rod, and the upper end of the box is provided with an infrared camera; The top surface of the cleaning table includes a flat surface and a third inclined surface. The side of the cleaning table is provided with a door and a first water outlet. The third inclined surface is provided with a groove. The cleaning table is provided with a first inclined surface and a second inclined surface. The first inclined surface is provided with a solid-liquid separation plate. The solid-liquid separation plate is provided with a liquid outlet. The first inclined surface is connected to a water storage tank. The water storage platform has a first water inlet on its side and a second water outlet at its rear. The water storage platform has a water storage tank inside, and the first water inlet and the first water outlet are connected by a first bend pipe. The pumping device has a third and a fourth water outlet at its front. The third water outlet is connected to the top side cleaning water pipe via a first flexible hose, and the fourth water outlet is connected to the bottom cleaning water pipe via a second flexible hose. A second water inlet is located on the side of the pumping device, and the second inlet is connected to the second water outlet via a second bend. The top side cleaning water pipe and the bottom cleaning water pipe are connected to the first and second flexible hoses respectively, allowing the cleaning truck to enter containers of different lengths. The pumping device remains stationary, drawing water from the water storage platform via the second bend. During the cleaning process, only the first and second flexible hoses extend laterally to minimize the impact of the cleaning truck's movement on the second flexible hoses and the bend.

[0005] Furthermore, a first fixing frame is provided inside the box, and a rolling brush is provided on the side end of the first fixing frame.

[0006] Furthermore, the hollow plate is located at the side end of the box body, and the hollow plate serves as the base for the positioning device.

[0007] Furthermore, a second fixing frame is provided at the upper end of the box, and the infrared camera is mounted on the second fixing frame.

[0008] Furthermore, both the top and bottom cleaning water pipes are equipped with fan-shaped nozzles.

[0009] Furthermore, the fan-shaped nozzles on the bottom cleaning water pipe form a ° angle with the vertical direction. Therefore, when moving, the water jets generated by the fan-shaped nozzles have a pushing effect on the residue inside the container. When the cleaning truck reaches the bottom of the container, the residue is simultaneously pushed to the bottom of the container by the water jets, and the waste scoop can collect the residue.

[0010] Furthermore, traditional container cleaning trucks require auxiliary tracks for positioning when entering the container, which is not only cumbersome to install but also greatly affects the container cleaning efficiency. In this invention, after the cleaning truck enters the container, the universal wheels at both ends of the cleaning truck contact the side walls of the container, and at the same time, the high-pressure springs are compressed to balance the forces at both ends of the container, so that the container is positioned in the middle 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 truck can be centered inside different containers.

[0011] Furthermore, after the container cleaning is completed, the waste scoop is removed along with the cleaning vehicle from the container. The wastewater and a small amount of residue not collected by the waste scoop are carried out of the container by the rear baffle of the waste scoop and flow to the third inclined plane. On the third inclined plane, the wastewater and a small amount of residue enter the trough due to gravity. After passing through the first inclined plane, the wastewater and a small amount of residue are separated by the solid-liquid separation plate. The solid-liquid separation plate is equipped with oil-absorbing material to further remove oil from the wastewater. The separated wastewater flows through the solid-liquid separation plate and then through the second inclined plane into the water storage tank. The water storage tank continues to settle the residue that has been subjected to secondary treatment. Finally, the wastewater after the residue has settled flows to the water storage tank through the first outlet.

[0012] Furthermore, the cleaning vehicle is equipped with top and side cleaning water pipes and bottom cleaning water pipes, with different diameters for the two types of pipes to accommodate different cleaning requirements for different surfaces of the container.

[0013] Furthermore, since the bottom surface of the container is dirtier than the top and sides, the top and bottom cleaning water pipes can clean different surfaces of the container with different focuses. The container is equipped with rolling brushes at both ends, which can absorb water from the sides of the container after cleaning.

[0014] Compared with the prior art, the present invention has the following advantages: (1) This container cleaning truck achieves fully automatic cleaning and waste collection of different wall surfaces of the container during the cleaning process inside the container. At the same time, the physical positioning device of the mobile cleaning truck enables the mobile cleaning truck to maintain its center position when entering the container, reducing the power requirements of the water pump and labor costs. The universal wheels at both ends of the cleaning truck contact the side walls of the container, and the compression springs balance the forces at both ends of the cleaning truck, so that the cleaning truck is positioned in the middle of the container. The container cleaning truck has a top side cleaning water pipe and a bottom cleaning water pipe running through it. The two types of water pipes have different diameters to adapt to the different cleaning requirements of different wall surfaces of the container.

[0015] (2) The container cleaning vehicle is equipped with two rotatable infrared cameras on the top. After the container top is cleaned, it can collect images of the container top. The collected images can be processed to determine whether there are cracks on the container top and where the cracks are located. The accuracy of crack detection using the improved YOLOv5 is improved by about 20%.

[0016] (3) The cleaning platform is divided into an inclined section and a flat section. The inclined section can send the wastewater and uncollected residue generated after container cleaning to the trough through water flow. After entering the cleaning platform, the wastewater and residue are separated by a solid-liquid separation device. The residue inside the cleaning platform can be removed by opening the box doors on both sides of the cleaning platform.

[0017] (4) The treated wastewater can be reused, avoiding waste of water resources. The solid-liquid separation plate inside the cleaning station separates the small amount of uncollected residue and the wastewater generated after cleaning. The doors on both sides of the cleaning station can be opened to facilitate the disposal of residue. The fan-shaped nozzles on the bottom cleaning water pipe are at a 45° angle to the vertical direction. Therefore, when moving, the water jet generated by the fan-shaped nozzles has a pushing effect on the residue inside the container. When the cleaning vehicle reaches the bottom of the container, the residue is pushed to the bottom of the container by the water jet. The waste scoop can collect the residue.

[0018] (5) The cleaning vehicle uses a simple structure for positioning and does not require track assistance. After the cleaning vehicle enters the container, the universal wheels at both ends of the cleaning vehicle contact the side walls of the container. At the same time, the high-pressure spring is compressed to balance the force at both ends of the container, so that the container is in the middle position of the container. The different curvatures 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 position inside different containers.

The top side cleaning water pipe 302 and the bottom cleaning water pipe 303 are connected to the first flexible hose G2 and the second flexible hose G3, respectively, allowing the cleaning vehicle 3 to enter containers of different lengths. The pumping device 6 remains stationary, and water is pumped from the water storage platform 5 via the second bend G4. During the cleaning process, only the first flexible hose G2 and the second flexible hose G3 extend laterally to reduce the impact of the cleaning vehicle 3 on the second flexible hose G3 and the second bend G4 during its movement.

[0023] In a specific embodiment, a first fixing frame 306 is provided inside the housing 301, and a rolling brush 307 is provided on the side end of the first fixing frame 306.

[0024] In a specific embodiment, the hollow plate 308 is disposed on the side end of the box body 301, and the hollow plate 308 serves as the base of the positioning device.

[0025] In a specific embodiment, a second fixing frame 314 is provided on the upper end of the housing 301, and the infrared camera 315 is mounted on the second fixing frame 314.

[0026] In a specific embodiment, both the top side cleaning water pipe 302 and the bottom cleaning water pipe 303 are equipped with fan-shaped nozzles 304.

[0027] In a specific embodiment, the fan-shaped nozzle 304 on the bottom cleaning water pipe 303 forms a 45° angle with the vertical direction. Therefore, when moving, the water jet generated by the fan-shaped nozzle 304 has a pushing effect on the residue inside the container 2. 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 scoop 305 can collect the residue.

[0028] In a specific implementation, traditional container cleaning vehicles require auxiliary tracks for positioning when entering the container. This not only makes track installation cumbersome but also significantly affects container cleaning efficiency. In this invention, after the cleaning vehicle 3 enters the container 2, the universal wheels 311 at both ends of the cleaning vehicle 3 contact the side walls of the container 2. At the same time, the high-pressure springs 313 are compressed to balance the forces at both ends of the container body 301, so that the container body 301 is positioned in the middle of the container 2. The different curvatures of the high-pressure springs 313 can adapt to the cleaning of containers of different widths, ensuring that the cleaning vehicle 3 can be centered inside different containers 2.

[0029] In a specific implementation, after the container 2 is cleaned, the waste hopper 305 exits along with the cleaning vehicle 3. The wastewater and a small amount of residue not collected by the waste hopper 305 are carried out of the container by the rear baffle of the waste hopper 305 and flow to the third inclined surface 402. On the third inclined surface 402, the wastewater and a small amount of residue enter the trough 404 due to gravity. After passing through the first inclined surface 408, the wastewater and a small amount of residue are separated by the solid-liquid separation plate 406. The solid-liquid separation plate 406 is equipped with oil-absorbing material to further remove oil from the wastewater. The separated wastewater flows through the solid-liquid separation plate 406 and then through the second inclined surface 409 before entering the water storage tank 410. The water storage tank 410 continues to settle the residue that has been subjected to secondary treatment. Finally, the wastewater after the residue has settled flows to the water storage tank through the first outlet 405.

[0030] In a specific implementation, the cleaning vehicle 3 has a top and side cleaning water pipe 302 and a bottom cleaning water pipe 303 running through its interior. The two types of water pipes have different diameters to adapt to the different cleaning requirements of different walls of the container 2.

[0031] In a specific implementation, 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 rinse different surfaces of the container with different focuses. The container body 301 is equipped with rolling brushes 307 at both ends, which can absorb water from both sides of the container 2 after cleaning.

[0032] Components not described in detail in this embodiment are all existing components that can be purchased through public channels.
