Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wharf structure, and more particularly to a powder unloading wharf structure based on a screw ship unloader. BACKGROUND

[0002] In port and wharf operations, especially when handling cement and other powdery materials, efficient, environmentally friendly and safe unloading operations have always been the focus of the industry. Traditional unloading methods, such as manual operation or the use of grab buckets and other mechanical tools, have many limitations. For example, these methods are often inefficient, time-consuming, and can cause material to scatter during unloading, not only causing environmental pollution, but also increasing material loss. Especially for cement and other powders, due to their fine particle characteristics and tendency to fly, if not controlled during unloading, a large amount of dust will be generated, not only affecting air quality, but also possibly posing a threat to the surrounding environment and human health.

[0003] In the wharf environment, facing different tonnage ships, complex weather conditions and different types of powder unloading demands, the traditional screw ship unloader often has difficulty in balancing efficient operation and good adaptability. Especially for cement and other powders, how to effectively control dust flying during unloading, prevent material scattering, and maintain operation efficiency has become a problem to be solved.

[0045] like Figures 1 to 4 As shown, this application provides a powder unloading terminal structure based on a screw unloader 3, including an unloading terminal and a screw unloader 3.

[0046] The unloading wharf comprises an offshore water jetty 1 and a canopy 2. The offshore water jetty 1, constructed within the water, not only avoids occupying shoreline resources but is also particularly suitable for special scenarios where land reclamation is strictly limited and the construction of impermeable structures is prohibited. Both sides of the offshore water jetty 1 are capable of berthing ships, simultaneously meeting the needs of two-way berthing and improving the utilization efficiency of the unloading wharf. There are at least two offshore water jetties 1, arranged parallel to each other, providing support for the canopy 2 structure. The canopy 2 spans two or more offshore water jetties 1, with the water below serving as the unloading area. The canopy 2 not only provides a sheltered space for unloading cargo ships, effectively resisting the effects of strong winds and heavy rains, but also provides a relatively stable working environment for unloading operations, freeing them from weather constraints. Simultaneously, the canopy 2 prevents dust generated during unloading from spreading to the outside environment, ensuring the environmental friendliness and efficiency of the cargo unloading process. The water area outside the canopy 2 serves as a barge area, enabling the orderly scheduling and berthing of vessels and further improving the operational efficiency of the wharf. The screw unloader 3 is located inside the canopy 2 and above the unloading area, and can directly unload powder materials from the hull.

[0047] like Figures 1 to 4 As shown in a specific embodiment of this application, the offshore water walkway 1 includes pile foundations 11 and a terrace 12. One end of the pile foundation 11 is inserted into the underwater strata, and the terrace 12 is connected to the other end of the pile foundation 11. The pile foundation 11 serves as the supporting foundation for the offshore water walkway 1. One end of the pile foundation 11 is inserted into the underwater strata, such as the seabed, riverbed, or lakebed, to effectively resist the impact of natural forces such as water flow and waves, ensuring the safety and reliability of the walkway during long-term use. Water flow can also pass through the gaps between the pile foundations 11, reducing the resistance of the offshore water walkway 1 in the water. The terrace 12 serves as the usage platform for the offshore water walkway 1 and is connected to the other end of the pile foundation 11. The terrace 12 is used to meet the needs of personnel walking and working, and its surface can accommodate various loading and unloading equipment and personnel activities.

[0048] like Figures 1 to 4As shown, in one specific embodiment of this application, the canopy 2 includes walls 21 and a roof 22. The walls 21 are erected on the terrace 12, serving as the supporting structure for the canopy 2; the roof 22 covers the walls 21, and the walls 21 and roof 22 together form a storage space for accommodating the unloading vessel. Under the sheltering effect of the walls 21 and roof 22, the unloading vessel is provided with a storage environment that offers a certain degree of wind and rain protection. To ensure the durability and corrosion resistance of the entire canopy 2 structure, the walls 21 can be made of high-strength, corrosion-resistant building materials, such as reinforced concrete or specially treated steel. The roof 22 can be made of lightweight, high-strength materials, such as color steel plates or aluminum-magnesium-manganese alloy plates. These materials not only have good waterproof and fireproof properties but can also effectively resist the attack of harsh weather.

[0049] like Figures 1 to 4 As shown, in one specific embodiment of this application, the wall 21 is provided with a skylight 211 and a roller shutter 212. The skylight 211 allows natural light to enter, providing good illumination for the interior space. Multiple skylights 211 are evenly distributed across the wall 21 to ensure uniform light distribution within the room. The skylights 211 are located above the roller shutters 212, avoiding interference with access passages. The wall 21 is also equipped with multiple roller shutters 212 to meet the traffic needs of the canopy 2's interior and exterior. During typhoons or hurricanes, the skylights 211 and roller shutters 212 can be opened to provide ventilation and pressure relief, reducing wind resistance and ensuring the structural safety of the canopy 2.

[0050] In one specific embodiment of this application, a dust removal device (not shown) is also provided inside the canopy 2. The dust removal device is used to spray the unloading ship and its surrounding environment to effectively suppress and remove dust, thereby improving the cleanliness and safety of the working environment.

[0051] During the unloading or transfer of materials on the unloading vessel, the dust removal device can automatically identify and respond to the dust generated during the operation, and promptly activate the spray mode. Fine water mist particles are evenly dispersed in the air, colliding and combining with suspended dust particles, which then settle under gravity, thereby achieving the purpose of dust removal.

[0052] like Figures 1 to 4 As shown, in one specific embodiment of this application, the canopy 2 further includes photovoltaic panels 23, which are installed on the roof 22. The photovoltaic panels 23 can convert sunlight into electrical energy, which can be directly used for lighting, dust removal, and other systems inside the canopy 2, and can also be stored through an energy storage device for unforeseen needs. The installation of photovoltaic panels 23 enhances the energy self-sufficiency of the powder unloading terminal structure, achieving emission reduction or zero emissions during operation.

[0053] like Figure 5As shown, in a specific embodiment of this application, the screw unloader 3 includes guide rails 31, crossbeams 32, a crossbeam moving device 33, a screw unloading device, and a screw unloading moving device 34. Specifically, the guide rails 31 are installed in pairs and parallel to each other on the columns of the canopy 2 to ensure the stability and safety of the entire screw unloader 3. The guide rails 31 not only serve as load-bearing and guiding structures but also define the basic operating path of the unloader. The crossbeams 32 span across and are erected between the paired guide rails 31. The shape and specifications of the crossbeams 32 must consider load-bearing capacity and structural strength to support the various equipment installed on them. The crossbeam moving device 33 is movably connected to the guide rails 31, and its function is to drive the crossbeams 32 and all the equipment mounted on them to move longitudinally along the guide rails 31, thereby enabling the unloader to adjust its position along the length of the cargo ship to adapt to cargo ships of different lengths. The crossbeam moving device 33 can specifically be a traveling crane. The screw unloading device is installed on the crossbeams 32. Since existing equipment can be used for the screw unloading device, its structure and working principle will not be described in detail. The screw unloading moving device is movably connected to the crossbeam 32 and carries the screw unloading device. Specifically, the screw unloading moving device can also be a traveling crane. Driven by the screw unloading moving device, the screw unloading device can move laterally along the crossbeam 32, thus covering the width direction of the cargo ship. With the coordinated action of the crossbeam moving device 33 and the screw unloading moving device, this screw unloader 3 can achieve free movement of the screw unloading device in the length and width directions of the cargo ship, thereby ensuring comprehensive unloading of the powder loaded on the cargo ship.

[0054] In one specific embodiment of this application, the screw unloader 3 further includes a first conveyor belt assembly (not shown) and a second conveyor belt assembly (not shown). The first conveyor belt assembly is mounted on a crossbeam 32, and the second conveyor belt assembly is mounted on a guide rail 31. One end of the first conveyor belt assembly is located at the discharge end of the screw unloader. The screw unloader, through its internal screw mechanism, conveys the material from the cargo ship onto the conveyor belt of the first conveyor belt assembly. The other end of the first conveyor belt assembly extends above the second conveyor belt assembly, thereby transferring the material from the first conveyor belt assembly to the conveyor belt of the second conveyor belt assembly for continued conveying to a designated location. The material starts from the discharge end of the screw unloader, undergoes initial conveying by the first conveyor belt assembly, and then further transfer by the second conveyor belt assembly, ultimately arriving at the predetermined stacking or processing location.

[0055] like Figure 5As shown, in one specific embodiment of this application, the screw unloading device includes an unloading arm 35. One end of the unloading arm 35 is vertically connected to the body of the screw unloading device, and a hydraulic cylinder is used as a driving element to realize the vertical lifting and lowering movement of the end of the unloading arm 35 to adapt to changes in the height of the material pile. The other end of the unloading arm 35 is connected to a suction head, which moves along the length of the crossbeam 32 under the swing of the unloading arm 35, expanding its working coverage. The suction head is specifically connected to the screw unloading device to realize the transportation of materials. Through the lifting and lowering movement of the unloading arm 35, the swing of the unloading arm 35, and the synergistic action of the crossbeam moving device 33 and the screw unloading moving device 34, the suction head can reach all corners of the material pile, thereby improving the comprehensiveness of material unloading.

[0056] like Figure 5 As shown, in one specific embodiment of this application, an infrared ranging device 4 is also included. The infrared ranging device 4 is installed on the suction head, or on the crossbeam 32, or both the suction head and the crossbeam 32 are equipped with infrared ranging devices 4. The infrared ranging device 4 installed on the suction head is used to monitor the dynamic changes in the height of the material pile surface in real time, so as to guide the suction head to make adaptive adjustments according to the fluctuations in the height of the pile surface, ensuring that the unloading process is uniform and continuous, effectively avoiding the formation of material pits due to excessive local digging. Once material pits are formed, not only may the material slump increase, increasing the risk of dust, but also the unloading efficiency may fluctuate greatly due to the uneven burial depth of the suction head. On the other hand, the infrared ranging device 4 installed on the crossbeam 32 is used to track the walking position of the negative pressure device or the suction head, so as to obtain the position information of the negative pressure device or the suction head in real time, and then adjust its walking speed to ensure that the suction head walks evenly on the material pile surface without leaving any untreated dead corners. Thus, while ensuring the unloading quality, it saves the extra steps of using a cleaning machine later, further improving the overall operating efficiency and economy.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
