[0052] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0053] like Figure 1 and Figure 2As shown, the present application provides a negative pressure ship unloader, including a guide rail 1, a crossbeam 2, a crossbeam moving device 3, a negative pressure device 4 and a negative pressure moving device 5. Specifically, the guide rails 1 are installed in pairs on an external support structure, such as a column of a dock, to ensure the stability and safety of the entire ship unloader system. The guide rails 1 not only serve as a load-bearing and guiding structure, but also define the basic path for the operation of the ship unloader. The crossbeam 2 spans and is erected between the guide rails 1 arranged in pairs. The shape and specifications of the crossbeam 2 need to consider the bearing capacity and structural strength to support various types of equipment installed thereon. The crossbeam moving device 3 is movably connected to the guide rail 1, and its function is to drive the crossbeam 2 and all equipment mounted thereon to move longitudinally along the guide rail 1, so that the ship unloader can adjust its position along the length direction of the cargo ship to adapt to cargo ships of different lengths. The negative pressure device 4 is installed on the crossbeam 2. The negative pressure device 4 includes components such as an air lock unloader 41, a material-gas separator 42, a fan protection device 43 and a Roots vacuum pump 44. As a power source, the Roots vacuum pump 44 is responsible for generating the necessary negative pressure environment to provide power for the extraction of powder. The fan protection device 43 ensures the stable operation of the Roots vacuum pump 44 under harsh working conditions and extends its service life. The material-gas separator 42 is responsible for separating the material from the airflow to ensure the purity and efficiency of material collection. The air lock unloader 41 is used to maintain the stability of the negative pressure airflow to prevent leakage and blockage of the powder during transportation. Since the air lock unloader 41, the material-gas separator 42, the fan protection device 43 and the Roots vacuum pump 44 are all existing equipment, their specific structures and working principles will not be described in detail. The negative pressure moving device 5 is movably connected to the beam 2 and carries the negative pressure device 4. Driven by the negative pressure moving device 5, the negative pressure device 4 can move laterally along the beam 2 to cover the width direction of the cargo ship. Under the coordinated action of the crossbeam moving device 3 and the negative pressure moving device 5, the negative pressure ship unloader of the present application can realize the free movement of the negative pressure device 4 in the length and width directions of the cargo ship, thereby ensuring the full range of unloading operations for the powder loaded on the cargo ship.
[0054] like Figure 1 and Figure 2As shown, in a specific embodiment of the present application, the negative pressure device 4 includes a discharge arm 6. One end of the discharge arm 6 is connected to the negative pressure device 4 in a liftable manner, and a hydraulic cylinder is used as a driving element to realize the lifting and lowering movement of the end of the discharge arm 6 in the vertical direction to adapt to the change in the height of the pile surface of the material pile. The other end of the discharge arm 6 is connected to a suction head, which is hinged to the discharge arm 6, giving the suction head the ability to swing freely along the length direction of the beam 2, thereby expanding its working coverage. The suction head is specifically connected to the negative pressure device 4 to ensure that the suction force generated by the negative pressure device 4 can be transmitted to the suction head, thereby realizing effective adsorption and transportation of the material. Through the lifting and lowering movement of the discharge arm 6, the swinging of the suction head, and the coordinated action of the beam moving device 3 and the negative pressure moving device 5, the suction head can reach every corner of the material pile, thereby improving the comprehensiveness of material unloading.
[0055] like Figure 2 As shown, in a specific embodiment of the present application, the negative pressure ship unloader also includes an infrared distance measuring device 7. The infrared distance measuring device 7 is installed on the suction head, or installed on the crossbeam 2, or the suction head and the crossbeam 2 are both installed with the infrared distance measuring device 7. The infrared distance measuring device 7 installed on the suction head is used to monitor the dynamic changes of the pile surface height in real time, so as to guide the suction head to make adaptive adjustments according to the fluctuations of the pile surface height, ensure that the unloading process is uniform and continuous, and effectively avoid the formation of material pits due to local excessive excavation. Once a material pit is formed, it may not only cause the material slump to increase and increase the risk of dust, but also may cause a large fluctuation in the unloading efficiency due to the different buried depths of the suction head. On the other hand, the infrared distance measuring device 7 installed on the crossbeam 2 is used to track the walking position of the negative pressure device 4 or the suction head, so as to obtain the position information of the negative pressure device 4 or the suction head in real time, and then adjust its walking speed to ensure that the suction head walks evenly on the pile surface without leaving any unprocessed dead corners, thereby ensuring the unloading quality while eliminating the additional steps of using the subsequent warehouse cleaning machine, further improving the overall operation efficiency and economy.
[0056] like Figures 1 to 5 As shown, the present application also provides a powder material ship unloading dock structure, including a ship unloading dock and the negative pressure ship unloader in the above embodiment. Since the powder material ship unloading dock structure includes the negative pressure ship unloader in the above embodiment, it also has the advantages of the negative pressure ship unloader in the above embodiment.
[0057] like Figures 1 to 5As shown, in a specific embodiment of the present application, the unloading terminal includes an offshore water plank road 8 and a canopy 9. The offshore water plank road 8 is built in the water area, which not only avoids the occupation of shoreline resources, but is also particularly suitable for those scenarios where land reclamation is strictly restricted and the construction of non-permeable projects is prohibited. The structural feature of the offshore water plank road 8 is that both sides of it have the ability to dock ships. The number of offshore water planks 8 is at least two, and these planks are arranged parallel to each other to provide support for the canopy 9 structure. The canopy 9 is straddled on two or more offshore water planks 8, and the water area below the canopy 9 is the unloading area, which not only provides a sheltered space for the unloading cargo ship to effectively resist the influence of bad weather, such as strong winds, heavy rains, etc., but also provides a relatively stable working environment for the unloading operation of the cargo, so that the unloading operation is no longer affected by weather conditions; it can also prevent the dust generated during unloading from spreading to the outside world, ensuring the environmental protection and efficiency of the cargo unloading process. The water area outside the canopy 9 is used as a barge area (such as Figure 1 and Figure 4 The system can realize the orderly dispatch and berthing of ships.
[0058] like Figures 1 to 5 As shown, in a specific embodiment of the present application, the offshore underwater plank road 8 includes a pile foundation 81 and a terrace 82. Among them, one end of the pile foundation 81 is inserted into the underwater stratum, and the terrace 82 is connected to the other end of the pile foundation 81. The pile foundation 81 serves as the supporting foundation of the offshore underwater plank road 8. One end of the pile foundation 81 is inserted into the underwater stratum, such as the seabed, riverbed, lakebed, etc., to effectively resist the impact of natural forces such as water flow, wind and waves, and ensure the safety and reliability of the plank road in long-term use. The water flow can also pass through the gaps between the pile foundations 81 to reduce the resistance of the offshore underwater plank road 8 in the water. The terrace 82 serves as a use platform for the offshore underwater plank road 8 and is connected to the other end of the pile foundation 81. The terrace 82 is used to meet the needs of people walking and working, and its surface can accommodate various loading and unloading equipment and personnel activities.
[0059] like Figures 1 to 5 As shown, in a specific embodiment of the present application, the canopy 9 includes a wall 91 and a roof 92. The wall 91 is erected on the terrace 82 as a supporting structure of the canopy 9; the roof 92 is built on the wall 91, and the wall 91 and the roof 92 enclose a storage space for accommodating the unloading boat. Under the shielding effect of the wall 91 and the roof 92, a storage environment with certain wind and rain protection capabilities is provided for the unloading boat. In order to ensure the durability and corrosion resistance of the entire canopy 9 structure, the wall 91 can be made of high-strength, corrosion-resistant building materials, such as reinforced concrete or specially treated steel. The roof 92 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 also can effectively resist the invasion of bad weather.
[0060] like Figures 1 to 5 As shown, in a specific embodiment of the present application, a skylight 911 and a rolling door 912 are provided on the wall 91. The skylight 911 can introduce natural light to provide good lighting for the interior space. There are multiple skylights 911, which are evenly distributed on the wall 91 to ensure the uniformity of indoor light distribution. The skylight 911 is located above the rolling door 912 to avoid conflict with the entrance and exit passages. The wall 91 is also equipped with multiple rolling doors 912 to meet the traffic needs inside and outside the canopy 9. When a typhoon or hurricane comes, the skylight 911 and the rolling door 912 can be opened to ventilate and relieve pressure, reduce wind resistance, and ensure the safety of the canopy 9 structure.
[0061] In a specific embodiment of the present application, a dust removal device (not shown) is also provided in the cover 9, and the dust removal device is used to spray toward the unloading ship and its surrounding environment to achieve effective suppression and removal of dust, thereby improving the cleanliness and safety of the working environment.
[0062] During the unloading or transfer of materials by the unloading ship, the dust removal device can automatically identify and respond to the dust generated by the operation and start the spray mode in time. The fine water mist particles are evenly dispersed in the air, collide and combine with the suspended dust particles, and then settle under the action of gravity, thereby achieving the purpose of dust removal.
[0063] like Figures 1 to 5 As shown, in a specific embodiment of the present application, the canopy 9 also includes a photovoltaic panel 93, which is installed on the roof 92. The photovoltaic panel 93 can convert sunlight into electrical energy, which can not only be directly supplied to the lighting, dust removal and other systems inside the canopy 9, but can also be stored through an energy storage device for emergency use. The installation of the photovoltaic panel 93 improves the energy self-sufficiency of the powder unloading terminal structure and achieves emission reduction or zero emission during operation.
[0064] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
