Description

Technical Field

[0001] The utility model relates to the field of reef blasting boats, in particular to a reef blasting boat with a buffer structure. Background Art

[0002] As a mobile water operation platform, reef blasting vessels use the drilling tools they carry to drill holes in underwater reefs through the water layer and carry out blasting operations to widen and deepen the water area. They are one of the main means of developing, improving and maintaining waterways and port waters.

[0003] When a reef-blasting ship is sailing on the water, it has to get close to the reef to operate the drilling rig to drill holes in the reef. Therefore, there is a situation where the distance between the ship and the reef is not well controlled, resulting in the hull hitting the reef. Although the reef-blasting ship has a low sailing speed and the impact force is small, it will still cause a certain degree of damage to the hull.

[0004] Therefore, in view of the situation that the above-mentioned reef-blasting boat is prone to collide with reefs and cause damage to the hull when sailing on the water surface and close to reefs, a reef-blasting boat with a buffer structure hidden at the bottom of the hull can be designed. According to the navigation conditions of the ship, it is reasonable to choose whether to use the buffer structure to protect the hull from impact damage. Utility Model Content

[0005] In order to overcome the problem that reef-blasting boats are prone to collision with reefs and cause damage to the hull when sailing on the water surface close to reefs.

[0006] The technical solution of the utility model is: a reef blasting boat with a buffer structure, comprising a hull, a drilling rig installed on the bow, a slide rail, a buffer assembly, an axle head, a steering motor, a support assembly, an abutment assembly, a fastening bolt, and a propeller; the slide rails are symmetrically arranged in two groups and fixedly installed on the lower plane of the hull, a buffer assembly is arranged between the slide rails, a steering motor and an axle head fixedly connected to the transmission shaft of the steering motor are installed on the buffer assembly, a Y-shaped support assembly parallel to the bottom plane of the hull is fixedly installed on the axle head, the abutment assembly is installed in the middle of the support assembly and extends obliquely upward to the front of the bow, the support assembly and the abutment assembly are tightened and locked by a fastening bolt, and a propeller is installed on the upper end of the abutment assembly.

[0007] Preferably, the buffer assembly, the support assembly and the abutment assembly are arranged on the bottom plane of the hull of the reef blasting vessel, and the support assembly and the abutment assembly are controlled by a steering motor to rotate to the bow. When the vessel approaches the reef, the reef collides with the support assembly and the abutment assembly in advance, and the impact force generated is absorbed by the buffer assembly.

[0008] Preferably, the buffer assembly includes an axle seat, an end plate, and a sliding rod; the axle seat is arranged between two sliding rails and slides axially along the sliding rails, the rear end of the axle seat is fixedly connected to the end plate, the rear end of the end plate is fixedly connected to the sliding rod, the steering motor is installed on one side of the axle seat, the axle head is located in the middle of the axle seat and is fixedly connected to the transmission shaft of the steering motor, the steering motor controls the axle head to rotate in the axle seat, and the rotation angle is one hundred and eighty degrees, so as to rotate the support assembly and the abutment assembly to the bow or to the lower part of the hull to be hidden.

The spring has elastic elongation properties. In actual use, a layer of plastic bellows is also sleeved on the outside to prevent the spring from rusting. When the support assembly and the abutment assembly are subjected to the impact reaction force of the reef, the impact force is transmitted to the axle seat. While the compression spring contracts, the slide rod moves in the hole of the back plate, and absorbs the impact force with the help of the elastic deformation of the spring to provide a buffering effect.

[0010] Preferably, the support assembly includes a supporting fork and a connecting sleeve; the supporting fork is a steel rod with a Y-shaped structure, one end of the fork is facing the bow side of the hull, and the other end of the supporting fork is fixedly connected to the shaft head, and the outer side of the supporting fork is covered with a layer of rubber material with a thickness of 6cm-10cm. When facing a larger reef, the Y-shaped structure of the supporting fork will contact the reef before the abutting assembly, and the flexible contact between the rubber material on the surface of the supporting fork and the reef is utilized to further achieve a buffering effect.

[0011] Preferably, the abutment assembly includes a bracket, a connecting frame, and a protective ring; the bracket is composed of a hollow horizontal rod and an oblique rod, the outside of the bracket is covered with a layer of rubber material with a thickness of 6cm-10cm, the horizontal part of the bracket is fixedly connected to the connecting frame, the connecting frame is inserted into the connecting sleeve, and the top of the oblique rod of the bracket is welded and fixed with a protective ring.

[0013] Preferably, the propeller is composed of a drive module and turbine blades. The drive module is installed in the cavity of the oblique rod of the bracket, and the turbine blades are arranged in the middle of the guard ring and driven to rotate by the drive module. When the bracket rotates to the bottom of the hull, it is completely submerged in the water. In order to reduce the underwater resistance generated by it to the navigation of the ship, the propeller is used to push the water flow in the reverse direction at high speed to assist the ship to move forward. When the bracket rotates to the bow, the guard ring provides a surrounding protection for the propeller.

When the bracket 801 rotates to the bow, the guard ring 803 plays a surrounding and protective role on the propeller 10.

[0029] When working, the hull 1 sails on the water surface and gradually approaches the nearby reef. When it is about 30m away from the reef, the steering motor 6 is started to control the shaft head 5 to rotate 180 degrees in the shaft seat 401, so that the fork 701 and the bracket 801 rotate to the bow;

[0030] For larger reefs, the Y-shaped structure of the support fork 701 will contact the reef before the abutment assembly, transferring the impact force to the shaft seat 401, and the spring 405 is compressed, and the impact force is absorbed by the elastic deformation of the spring 405;

[0031] For smaller reefs, the reef enters from the fork of the support fork 701, the bracket 801 contacts the reef, and transmits the impact force to the shaft seat 401, and the spring 405 is compressed, and the impact force is absorbed by the elastic deformation of the spring 405;

[0033] Through the above steps, a buffer component, a support component and an abutment component are arranged on the bottom plane of the hull 1 of the reef blasting vessel. Before the vessel approaches the reef, the support component and the abutment component are propped up at the bow, and the impact force generated by the pre-collision between the reef and the support component and the abutment component is absorbed by the buffer component, thereby reducing the direct frontal impact damage to the vessel, so as to solve the problem that the reef blasting vessel is prone to collision with the reef and cause damage to the hull 1 when sailing on the water surface and approaching the reef.
