Description

Technical Field

[0001] This utility model relates to a long-distance detonation device for marine applications and belongs to the field of blasting. Background Technology

[0002] Traditional detonation methods in offshore blasting operations suffer from numerous problems, such as susceptibility to signal transmission interference, low energy transfer efficiency, and difficulty in guaranteeing detonation accuracy and reliability. These problems are particularly pronounced in long-distance detonation scenarios, severely restricting the safety and efficiency of offshore blasting operations. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a long-distance detonation device for marine operations, which realizes efficient, accurate and safe control of long-distance detonation at sea, and provides reliable technical support for blasting operations in marine engineering.

[0004] Technical Solution: To solve the above-mentioned technical problems, this utility model provides a long-range marine detonation device, including a laser excitation device and a monitoring drone located on the shore. A sea surface stabilization device is installed on the sea surface far from the shore. The sea surface stabilization device includes a float, on which an attitude stabilization device is installed. A worktable is provided on the attitude stabilization device. An optical lens is installed on one side of the worktable, and a laser shielding rod is installed on the other side. A detonation transmission fixing device is installed on the laser shielding rod. A groove is provided on the worktable, and a motor is placed inside the groove. The motor is fixed in the groove by a cover plate. The groove is connected to a through groove. A movable boss is connected below the laser shielding rod. The movable boss has... The threaded hole connects the motor to the screw, and the screw and threaded hole work together. The monitoring drone is connected to the controller, and the controller is connected to the motor. When long-distance marine blasting is required, the drone monitors and captures the size of the spot where the laser beam focused by the optical lens illuminates the focal point. The motor drives the screw to rotate, thereby moving the laser blocking rod and adjusting the distance between the optical lens and the detonation device. The laser beam generated by the laser excitation device is directed towards the optical lens, and its energy is focused to the focal point. The detonator in the detonation device located at the focal point is burned and detonated when it receives the focused laser energy, which in turn triggers the detonating cord to transmit the detonation.

[0005] Preferably, the detonation transmission fixing device includes a support block, in which a detonating cord reserved hole and a detonator reserved hole are provided, and a detonation transmission gap is provided between the detonating cord reserved hole and the detonator reserved hole. A laser irradiation hole is provided on the side of the support block near the detonator reserved hole, and the laser irradiation hole is connected to the detonator reserved hole.

[0006] Preferably, a mounting block is provided at the end of the movable boss, and the movable boss is locked in the through groove by the mounting block.

[0007] Preferably, the inner surface of the mounting block is equipped with rollers, which are located on the surface of the worktable.

[0008] Preferably, the attitude stabilization device includes a support gantry mounted on the float, a gravity stabilizer mounted on the support gantry, a connecting rod mounted on the gravity stabilizer, a counterweight at one end of the connecting rod, and a yaw axis stabilizer at the other end. The yaw axis stabilizer is connected in sequence to a roll axis stabilizer and a pitch axis stabilizer, and the pitch axis stabilizer is connected to a worktable.

[0009] Beneficial effects: The long-distance marine detonation device of this invention uses a laser excitation device to generate a laser beam that is directed towards a directional energy focusing device. No matter where the laser beam hits the directional energy focusing device, its energy will be focused to the focal point. Through the cooperation of a motor and a drone, the focal length can be finely adjusted. When the detonator in the detonation propagation device located at the focal point receives the focused laser energy, it is burned and detonated, thereby triggering the detonating cord to propagate the detonation. Due to the fine-tuning of the focal length, the reliability of the burning and detonation is higher. Throughout the detonation process, the sea surface stabilization device works in real time to reduce the impact of sea surface swaying on the device and ensure the accuracy and reliability of the detonation.
