AI Technical Summary
When existing dredging ships blast underwater, blasting gravel is prone to hit the bottom of the ship, resulting in high maintenance costs and inability to effectively protect them. The existing technology cannot reduce the maintenance costs of the bottom of the ship.
A structure for anti-collision ship underwater blasting dredging is designed. By setting up multiple independent anti-collision boards at the bottom of the ship, and using a combined structure of guide frames, guide grooves, guide blocks and damping springs, it prevents gravel from hitting and during impact. Shock reduction is performed and allow for individual replacement of damaged bumper plates.
Effectively protecting the bottom of the ship reduces the maintenance cost of the dredged ship, avoids gravel directly hitting the bottom of the ship, and reduces the difficulty of replacing the anti-collision plate through simple disassembly and assembly structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figures 1 to 3 The utility model provides a technical solution: an underwater blasting and dredging anti-collision ship bottom structure, comprising a bottom plate 1, anti-collision plates 5 are equidistantly arranged at the bottom of the bottom plate 1, and first guide frames 6 are equidistantly fixedly connected to the bottoms of both sides of the longer sides of the bottom plate 1, wherein:
[0020] A second guide frame 7 is installed on the top of the inner side of the anti-collision plate 5 corresponding to the first guide frame 6, a guide groove 8 is opened on the inner side of the first guide frame 6, a guide block 9 is fixedly connected to the outer side of the second guide frame 7 corresponding to the guide groove 8, and damping springs 10 are symmetrically installed on the bottom of the bottom plate 1 corresponding to the four corners of the anti-collision plate 5;
[0021] When a dredging ship encounters reefs while dredging, widening or deepening rivers, lakes and other waters, the reefs are cleared by underwater blasting. When blasting the reefs, when the gravel rushes to the bottom of the dredging ship, the gravel is blocked by the anti-collision plate 5, so that the gravel hits the anti-collision plate 5, and the impact is reduced by the damping spring 10 to prevent the dredging ship from shaking violently. At the same time, the bottom of the ship is protected by a plurality of independent anti-collision plates 5 to prevent the gravel from hitting the bottom of the ship, effectively protecting the bottom of the ship, and when the anti-collision plate 5 is damaged, the damaged anti-collision plate 5 can be replaced separately, effectively reducing the maintenance cost of the dredging ship.

The damping spring 10 and the bottom end of the second guide frame 7 are fixedly connected to the anti-collision plate 5 by bolts 11. When the anti-collision plate 5 is hit, the anti-collision plate 5 drives the guide block 9 to move in the guide groove 8. The guide structure formed by the guide block 9 and the guide groove 8 guides the movement of the anti-collision plate 5 during shock absorption to avoid the movement of the anti-collision plate 5 from being offset. When it is necessary to disassemble the anti-collision plate 5, the bolts 11 connecting the second guide frame 7, the damping spring 10 and the anti-collision plate 5 are removed to complete the disassembly of the anti-collision plate 5.

Through the installation structure of the anti-collision plate 5, it is convenient to disassemble and assemble a single anti-collision plate 5 so as to replace the anti-collision plate 5.
[0024] Working principle: This is an underwater blasting dredging anti-collision ship bottom structure. When a dredging ship encounters reefs while dredging, widening or deepening rivers, lakes and other waters, the reefs are cleared by underwater blasting. When blasting the reefs, when the crushed stones rush to the bottom of the dredging ship, the crushed stones are blocked by the anti-collision plate 5, so that the crushed stones hit the anti-collision plate 5, and the damping spring 10 is used to reduce the shock to prevent the dredging ship from shaking violently. At the same time, the bottom of the ship is protected by a plurality of independent anti-collision plates 5 to prevent the crushed stones from hitting the bottom of the ship, effectively protecting the bottom of the ship, and when the anti-collision plate 5 is damaged, the damaged anti-collision plate 5 can be replaced separately, which effectively reduces the maintenance cost of the dredging ship, and when the anti-collision plate 5 is hit The anti-collision plate 5 drives the guide block 9 to move in the guide groove 8. The guide structure formed by the guide block 9 and the guide groove 8 guides the movement of the anti-collision plate 5 during shock absorption to avoid deviation of the movement of the anti-collision plate 5. When it is necessary to disassemble the anti-collision plate 5, the bolts 11 connecting the second guide frame 7, the damping spring 10 and the anti-collision plate 5 are removed to complete the disassembly of the anti-collision plate 5. When installing the anti-collision plate 5, the damping spring 10 and the anti-collision plate 5 are first connected, and then the second guide frame 7 drives the guide block 9 to enter the guide groove 8, and then the second guide frame 7 and the anti-collision plate 5 are installed.
