Two moving wheels are fixedly connected to the left and right sides of the bottom of the collection frame 8 and are symmetrically distributed front and back. Brake pads are installed inside the moving wheels. A weighing sensor is installed at the bottom of the collection frame 8. The weighing sensor is a Mettler Toledo ICS685, which can monitor the total weight of hazardous substances in the collection frame in real time and form a double verification with the weighing data of the weighing frame 66.

[0024] When using: Preparation stage

[0025] First, check that all components of the device are intact. Confirm that the electric slide rail 4 and electric slider 5 can slide smoothly, the servo motor 62 is operating normally, the traction rope 65 is undamaged and is well wound on the take-up roller 64, check whether the weighing device 7 and the weighing sensor at the bottom of the collection box 8 have been calibrated to ensure that the data is accurate and reliable, move the collection box 8 to the appropriate position using the bottom moving wheels, and press the brake pads to fix it.

[0026] Lifting weighing frame

[0027] Start the electric slide rail 4 and electric slider 5 to move the weighing frame 66 above the hazardous substance to be weighed. Then start the servo motor 62 to control the rotating rod 63 to rotate, which drives the take-up roller 64 to release the traction rope 65, so that the weighing frame 66 is lowered to a suitable height so that the hazardous substance can be loaded into the weighing frame 66.

[0028] Weighing process

[0029] The servo motor 62 is restarted, and the traction rope 65 is wound up to lift the weighing frame 66 containing hazardous substances above the weighing device 7. Then, it is slowly lowered so that the weighing frame 66 is placed on the weighing device 7 for weighing. The weighing device 7 collects data in real time and synchronizes the data to an external display terminal or monitoring platform. During the weighing process, because the servo motor is linked to the external control system, a suitable lifting speed can be preset, ensuring the weighing frame remains stable even if the ship sways, thus preventing collisions that could damage the sensors.

[0030] Unloading process

[0031] After weighing is completed, the electric slider 5 is controlled to move the weighing frame 66 to the top of the material discharge port of the connecting base plate 3. The locking rod 69 is pulled, the compression spring 611 is compressed, and the flip cover 67 rotates around the hinge under the action of gravity and opens. The rotation angle is between 0 and 90°. The harmful substances automatically slide into the collection frame 8 through the material discharge port and the guide plate 9.

[0032] Data validation and subsequent processing

[0033] The Mettler Toledo ICS685 load cell built into the collection box 8 re-weighs the collected hazardous substances, forming a double verification with the weighing data of the weighing box 66 to ensure data consistency. After unloading and data verification are completed, the brake pads of the bottom moving wheels of the collection box 8 can be released, and the collection box 8 can be moved to the subsequent processing stage, such as the classification, storage or transportation of hazardous substances.

[0034] It is worth noting that the electric slide rail 4, electric slider 5, servo motor 62, and weighing device 7 mentioned in this application are all externally connected to a drive power supply and a control switch. Furthermore, the electric slide rail 4, electric slider 5, servo motor 62, and weighing device 7 are all conventional and known devices. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected using conventional methods such as bolts, rivets, and welding that are mature in the prior art. Moreover, the machinery, parts, and equipment all use conventional models in the prior art. In addition, the circuit connection uses conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.

[0035] In summary, this ship hazardous substance detection and weighing device, through the cooperation of the electric slide rail 4 and the electric slider 5, and the servo motor 62 driving the rotating rod 63 to drive the winding roller 64 to wind and unwind the traction rope 65, realizes the automated lifting and moving of the weighing frame 66. This design completely replaces manual handling, avoids direct contact by operators, reduces the handling risk of barrelled and bagged hazardous materials, reduces weighing risk, and improves the practicality of the device. The material discharge port of the connecting base plate and the guide plate 9 form a flow channel. After weighing, the weighing frame 66 moves above the material discharge port, and then the locking rod 69 is pulled to the left limit position. Block 68 detaches, and the flip-top 67 opens with the help of the hinge. The hazardous substance automatically slides down to the collection frame 8 through the guide plate 9. At the same time, the weighing data from the weighing frame 66 and the weighing sensor inside the collection frame 8 form a double verification, eliminating the need for manual emptying and thus facilitating unloading. This further improves the practicality of the device and solves the problem of early static weighing equipment such as weighbridges and platform scales, which required manual handling of hazardous substances to the weighing platform. For barrelled or bagged hazardous materials, there was a high risk of handling and weighing, and manual handling and unloading were also inconvenient after weighing.
