Description

Technical fields:

[0001] This invention belongs to the field of container technology and relates to an open-top container made of composite materials to prevent icing. Background technology:

[0002] Containers are modular tools capable of transporting packaged or unpackaged goods, facilitating loading and unloading with mechanical equipment. They offer convenient, fast, environmentally friendly, and low-carbon transportation. In the transportation of bulk commodities such as coal and sand, they reduce repeated loading and unloading, lower operating costs, and achieve clean transportation throughout the entire process—"no coal touching the ground," "point-to-point," and "door-to-door"—changing the traditional transportation model, significantly reducing cargo damage and environmental pollution, and achieving the goal of green freight. Based on the materials of the main components (side walls, end walls, roof, etc.), containers are mainly divided into three types: steel containers, aluminum alloy containers, and fiberglass containers. In addition, there are wooden containers, stainless steel containers, etc. Among them: Steel containers are made of steel, with advantages such as high strength, robust structure, excellent weldability, good watertightness, and low price; disadvantages such as heavy weight and poor corrosion resistance. Aluminum alloy containers are made of aluminum alloy, with advantages such as light weight, attractive appearance, corrosion resistance, good elasticity, easy processing, low processing and repair costs, and long service life; disadvantages such as high cost and poor weldability. Fiberglass containers are made of fiberglass, with advantages such as high strength, good rigidity, large internal volume, good heat insulation, corrosion resistance, chemical resistance, easy cleaning, and simple repair. Disadvantages such as heavy weight, susceptibility to aging, and reduced strength at bolt joints.

[0003] Currently, traditional open-top container trucks generally use metal materials. For example, Chinese Patent 202211202956 discloses a lithium battery energy storage container, which includes a container, battery clusters, combiner cabinets, fire cabinets, and air conditioners installed inside the container, with several channels between the air conditioner and the battery clusters. It also includes: multiple opening doors, located on the outside of the battery clusters, combiner cabinets, fire cabinets, and air conditioners, with the doors opening outwards; a coating applied to the container and the inner walls of the opening doors; and multiple fireproof components, also multiple, installed on the top of the container, corresponding to each... A novel container disclosed in Chinese Patent 202221853122 includes a container body and a rotating door. The rotating door is rotatably connected to one side of the container body. The interior of the container body is provided with storage space for accommodating goods. The rotating door opens or closes the storage space. A pull rod is provided on one side of the rotating door, and the pull rod is arranged vertically and fixed to the rotating door by multiple fastening seats. A support unit is provided on the rotating door. The support unit includes a pressure arm and a mounting bracket. Two mounting brackets are respectively provided on both sides of the pressure arm. One end of the pressure arm is connected to... The pull rod is fixedly connected, and a recess is provided in the middle of the pressure arm. The recess protrudes towards the surface of the revolving door. A notch is provided on the card seat, and the recess is accommodated in the notch. The notches on the card seats on both sides of the pressure arm are respectively pressed against the two sides of the recess. Chinese Patent 201820322193 discloses a detachable and combinable energy storage container structure, including a box body. The box body includes a front panel, a rear panel, a base frame, an upper left side beam, an upper right side beam, a left side plate, a right side plate, and a top plate. The base frame, the upper left side beam, the upper right side beam, the upper left side beam, the upper right side beam, the upper right side beam, and the top plate are all connected. The right-side beams are all positioned between the front and rear panels. The upper left and upper right beams are parallel and horizontally positioned, and both are located above the base frame. The left side plate is positioned between the upper left beam and the base frame, the right side plate is positioned between the upper right beam and the base frame, and the top plate is positioned between the upper left and upper right beams. All connections between the front panel, rear panel, base frame, upper left beam, upper right beam, left side plate, right side plate, and top plate are detachable. When transporting bulk goods such as coal and sand in winter, metal containers are prone to icing on their inner walls, which is extremely difficult to clean. Furthermore, the corrosion resistance and load-bearing capacity of open-top metal containers do not meet current technical requirements. Therefore, developing a new type of open-top container made of a novel material has significant social and economic benefits. Summary of the Invention:

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and to design an open-top container to solve the problems of icing and corrosion in the container compartment.

[0005] To achieve the above objectives, the main structure of the open-top container of the present invention includes a container body formed by a frame, a front wall panel, a left wall panel, a right wall panel, a bottom panel and a door panel, a tie rod between the left and right wall panels, and a reinforcing beam on the bottom panel; the inner wall of the container is flat and the joints are rounded, which effectively avoids problems such as cargo residue, and the service life is improved based on the high corrosion resistance of the composite material.

[0006] The invention relates to a front wall panel, a left wall panel, and a right wall panel, the outer surfaces of which are provided with structural columns with a design; a number of forklift openings are provided at equal intervals on the bottom plate; and a door lock is provided on the door panel.

[0007] The frame involved in this invention is formed by welding several metal beams to meet the load requirements of container use; the front wall panel, left wall panel, right wall panel, bottom plate, and reinforcing beams are all integrally molded from composite materials and are respectively bonded or bolted to the frame; the door panel is made of metal and is connected to the frame by hinges, and is equipped with a sealing strip to prevent cargo from spilling out; the tie rod is a detachable structure, set according to the nature of the transported goods. When transporting heavier goods such as coal and sand, it ensures that the left and right wall panels do not deform outwards, and can be omitted when transporting lighter goods; the forklift opening facilitates forklift transportation; the door lock has a handle on the lock rod and a cam at the bottom, which works in conjunction with the cam seat on the frame.

[0008] Compared with existing technologies, this invention uses a metal frame and door panels that meet the requirements for strength and load-bearing capacity. The inner surface of the container is flat, and the corners are rounded. When transporting bulk goods such as coal and sand, it avoids freezing and piling up, unlike traditional metal containers. The outer surface of the container features structural columns with unique designs, which enhance aesthetics while strengthening the front, left, and right wall panels. Through finite element analysis and other auxiliary calculations and simulation tests, the reliability and safety of the product are guaranteed to the greatest extent. Its reasonable structure and one-piece molding process reduce its weight, improve its load-bearing capacity and corrosion resistance, and extend its service life. It features antifreeze properties, easy installation and operation, an attractive appearance, and convenient maintenance. Attached image description:
