[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The object of the present invention is to provide a shipborne underwater obstacle-breaking equipment and an obstacle-breaking method, which can flexibly implement underwater obstacle-breaking operations and at the same time can meet the requirements of expelling aquatic organisms and destroying potential threat objects in the water during the navigation of the ship.

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] Embodiment 1

[0040] The embodiment of the present invention provides a shipborne underwater obstacle-breaking equipment, including: a capacitor discharge device, a launching device, and a plurality of electrodes 6. The capacitor discharge device, the launching device, and the plurality of electrodes 6 are all carried on the hull 8. The launching device is respectively connected to the plurality of electrodes 6, and the launching device is used to launch the electrodes 6 to underwater obstacles. The capacitor discharge device is respectively connected to the plurality of electrodes 6, and the capacitor discharge device is used to transmit high-voltage electricity to the electrodes 6 after the electrodes 6 are launched to underwater obstacles, and discharge through the electrodes 6 in the liquid, so as to blast or expel the underwater obstacles.

[0041] The high-voltage electricity discharges through the electrodes 6 in the liquid. According to the liquid-electric effect, that is, discharging in the liquid will generate destructive force on the surrounding medium. The action principle of the liquid-electric effect can be divided into three processes: generating a precursor breakdown, forming a discharge channel, and bubble pulsation according to time. The high-voltage electricity can break down the liquid medium, generate high temperature and high pressure in a short time, and be accompanied by a large amount of energy and shock waves. At the same time, a large amount of charge will remain on the outer shell of the hull 8, which can actively break through the obstacles during the navigation of the ship and corona the aquatic organisms near the ship.

[0042] The present invention adopts the electro-blasting technology as a means of underwater obstacle-breaking for ships. Since no toxic and harmful gases are generated during the electro-blasting process, it is green and environmentally friendly. At the same time, when the hull 8 is sailing in the water, the liquid discharge medium can be easily obtained. Since the traditional underwater obstacle-breaking means will pollute the environment and there are safety hazards in manual operation, the electro-blasting underwater obstacle-breaking has advantages compared with it.

[0043] Embodiment 2

[0044] Refer to Figure 1, an embodiment of the present invention provides a more specific shipborne underwater obstacle-breaking equipment, including: an AC power supply 1, a capacitor 4, a boost rectifier 3, a discharge switch 2, a transmitting device, and a plurality of electrodes 6.

[0045] The boost rectifier 3 is respectively connected to the AC power supply 1 and the capacitor 4. The boost rectifier 3 is used to boost the alternating current of the AC power supply 1 and convert it into a direct high-voltage current, and transmit the direct high-voltage current to the capacitor 4 for storage. The capacitor 4 is connected to the plurality of electrodes 6 through the discharge switch 2. The capacitor 4 is used to output all the stored energy and turn on the discharge switch 2 when the energy of the stored direct high-voltage current reaches the operating energy threshold of the discharge switch 2, and transmit the stored electrical energy to the electrodes 6 for release. For the positional relationship, connection relationship, and functions of the transmitting device and the plurality of electrodes 6, please refer to Embodiment 1 for details.

[0046] The AC power supply 1 charges the capacitor 4, stores it at a low voltage for a long time, and releases it at a high voltage for a short time to reach the breakdown voltage, activates the discharge switch 2, and all the energy stored in the capacitor 4 is released through the electrodes 6 within a short time (100 ms - 10 ns). Using high-voltage electrical pulses, the electrical energy is converted into internal energy and mechanical energy based on the liquid-electric effect. The electrical energy breaks down the discharge channel to generate high temperature, high pressure, explosion, electromagnetic field, and shock wave. The high temperature, high pressure, and shock wave can clear the obstacles during the navigation of the hull 8. The strong flash, strong sound, and electromagnetic field generated by the explosion can drive away the potentially threatening underwater creatures during the driving of the hull 8.

[0047] The boost rectifier 3 is connected to the capacitor 4 through a cable 5. The capacitor 4 is connected to the discharge switch 2 through a cable 5. The discharge switch 2 is connected to the electrodes 6 through a cable 5. One end of the cable 5 is connected to the electrodes 6 by crimping. The cable 5 is a 40 kV DC high-voltage coaxial cable with shielding, and the electrode 6 is a high-voltage stainless steel electrode 6.

[0048] Refer to Figure 2 , when using the shipborne underwater obstacle-breaking equipment, first, control the plurality of electrodes 6 to protrude from the hull 8 to an appropriate height so that the discharge effect range of the plurality of electrodes 6 can cover the target object.

[0049] Generally, the voltage for the AC power supply 1 to charge the capacitor 4 is 220 V or 380 V. Therefore, the boost rectifier 3 can boost 220 V or 380 V alternating current and convert it into 15 kV direct high-voltage current.

[0050] Among them, as Figure 3As shown, the launching device includes: a wireless remote control receiving system 9, a control switch 10, at least one catapult 11 and at least one retractor 12. The total number of catapults 11 and retractors 12 is equal to the number of electrodes 6. The wireless remote control receiving system 9 is connected to the control switch 10, and the wireless remote control receiving system 9 is used to remotely receive a trigger signal and transmit the trigger signal to the control switch 10. The control switch 10 is connected to each catapult 11 and each retractor 12 respectively, one catapult 11 is connected to one electrode 6 correspondingly, and one retractor 12 is connected to one electrode 6 correspondingly; the control switch 10 is used to control the catapult 11 to launch the electrode 6 onto the underwater obstacle to blast the underwater obstacle after receiving the trigger signal, and / or control the retractor 12 to transmit the electrode 6 to the target position to expel the aquatic organisms.

[0051] The catapult 11 can launch the electrode 6 to 30-100m, and the high electric energy is instantly released in the water between the two tips of the high-voltage electrode 6, causing the water to vaporize and expand to generate high temperature, high pressure, and explosion, mainly to blast obstacles. The telescope 12 can transmit the electrode 6 to 0-30m, and the discharge generates a magnetic field, an electric field, and an electrostatic protection layer, mainly to expel large organisms in the water.

[0052] The transmitting device further comprises: a power supply 7. The power supply 7 is connected to a wireless remote control receiving system 9. The power supply 7 is also an AC power supply 1, which provides energy for the transmitting device.

[0053] In order to make it easier to fix the electrode 6 on the fulcrum of the underwater obstacle, a claw-shaped hook is provided at the tip of the electrode 6 .

[0054] Compared with traditional underwater obstacle removal equipment, it has the following advantages:

[0055] 1) The electric blasting device relies on electrical energy and is an electromechanical device. There are no safety hazards during storage and transportation.

[0056] 2) It can discharge repeatedly, with the maximum discharge energy reaching 675KJ. The energy can be adjusted in stages, has a large range of action, low energy consumption, low cost, little impact from the underwater environment, and is suitable for various blasting conditions.

[0057] 3) Underwater electric blasting and obstacle removal operations do not release chemical substances, have low harm to aquatic organisms, and are environmentally friendly.

[0058] 4) Remote operation and control can be realized to ensure the safety of ship personnel during the discharge process.
