Description

Technical Field

[0001] This invention relates to the field of underwater acoustic repulsion technology in marine engineering, and particularly to a split electrode structure. Background Technology

[0002] In the high-intensity acoustic repulsion device, electrodes are used to generate a strong sound in seawater to drive away frogmen. An extremely high voltage is applied to the positive and negative poles of the electrodes, causing a momentary discharge, thus achieving the effect of a strong sound.

[0003] The current electrode scheme has the following problems: 1. In order to achieve a better discharge effect, the electrode is made of tungsten copper alloy. However, the alloy contains copper, which is not conducive to corrosion in seawater, resulting in a short electrode life, generally only about six months.

[0004] 2. To ensure electrode safety under high voltage conditions, a 50m long watertight cable is installed between the electrode and the charging / discharging equipment. If the electrode is damaged by corrosion, seawater will simultaneously enter the cable, causing damage and resulting in excessively high replacement costs. Summary of the Invention

[0005] The purpose of this invention is to provide a novel solution for a detachable electrode, which can effectively solve the problem of water leakage after multiple discharges of the electrode. The solution incorporates redundant protection design, which ensures both safety in use and ease of replacement, while also being more cost-effective.

[0006] The technical solution proposed in this invention is implemented as follows: A separable electrode structure includes an electrode structure (100), an electrode sealing cylinder (200), a high-intensity acoustic separation sealing chamber (300), a water leakage detector (24), a positive electrode wire (201), a negative electrode wire (203), a coaxial cable (202), multiple mounting components and sealing components. The electrode structure (100) is mounted on one end face of the electrode sealing cylinder (200), and the two are sealed by a small sealing ring (205). The water leakage detector (24) is mounted as a whole on the other end face of the electrode sealing cylinder (200). The positive electrode wire (201) is mounted on the other end face of the electrode sealing cylinder (200). 1) The negative electrode line (203) is installed in the cavity of the electrode sealing cylinder (200). The electrode sealing cylinder (200) is installed in the cavity of the strong sound expulsion sealing chamber (300). The coaxial cable (202) is placed outside the electrode sealing cylinder (200) and inside the cavity of the strong sound expulsion sealing chamber (300), and is connected to the electrode sealing cylinder (200) to achieve spatial isolation between the electrode structure (100) and the coaxial cable (203). The electrode sealing cylinder (200) and the strong sound expulsion sealing chamber (300) are sealed with a large sealing ring (204). The electrode structure (100) includes a positive electrode (1), a negative electrode (2), a negative electrode ring (3), a positive electrode pad (4), a negative electrode pad (5), a sealing cover plate (6), a positive electrode stud (7), a negative electrode screw (8), a terminal block (9), and insulating rubber (10). The positive electrode (1) and the negative electrode (2) are coaxial, and the negative electrode (2) and the negative electrode ring (3) are interference-fitted. Insulating rubber (10) is wrapped between the positive electrode (1), the negative electrode (2), and the negative electrode ring (3). The positive electrode (1) and the negative electrode (2) are left with only one side exposed to seawater. A positive electrode pad (4) is placed on the positive electrode (1), and a negative electrode pad (5) is placed on the negative electrode ring (3). Both the positive electrode pad (4) and the negative electrode pad (5) are made of insulating and elastic materials. The positive electrode (1) and the sealing cover (6) are fastened by the positive electrode stud (7), and the negative electrode ring (3), the terminal (9) and the sealing cover (6) are fixed by the negative electrode screw (8). The electrode sealing cylinder (200) includes a cylinder body (21), a positive electrode needle (22), a sealing O-ring (23), a small terminal block (25), and a negative electrode needle (26). The cylinder body (21) is made of non-metallic material. The positive electrode needle (22), the small terminal block (25), and the negative electrode needle (26) are all installed on one end face of the cylinder body (21). The positive electrode needle (22) and the negative electrode needle (26) are sealed to the cylinder body (21) by the sealing O-ring (23). The positive electrode (1), the negative electrode (2), the sealing cover plate (6), the positive electrode needle (22), and the negative electrode needle (26) are all provided with grooves to ensure the reliability of the connection of the insulating rubber (10) or the sealant (35).The leak detector (24) includes a small cover (31), a leak detection positive electrode (32), a leak detection negative electrode (33), a small sealing ring (34), and sealant (35). The small cover (31) is sealed with the leak detection positive electrode (32) and the leak detection negative electrode (33) by the sealant (35), and sealed with the cylinder (21) by the small sealing ring (34). The leak detector (24) is installed on one end face of the electrode sealing cylinder (200). The continuity between the leak detection positive electrode (32) and the leak detection negative electrode (33) can be used to determine whether the electrode sealing cylinder (200) is leaking seawater. One end of the positive electrode wire (201) in the cavity of the electrode sealing cylinder (200) is connected to the positive electrode stud (7), and the other end is connected to the positive electrode needle (22). One end of the negative electrode wire (203) is connected to the negative electrode screw (8), and the other end is connected to the negative electrode needle (26), so as to realize the electrical connection between the electrode structure and the coaxial cable (202). The coaxial cable (203) contains two core cables, which serve as positive and negative cables respectively. The positive cable is connected to the positive pin (22), and the negative cable is connected to the negative pin (26). After the connection is made, the coaxial cable (202) is wrapped around the outside of the cylinder (21).

[0007] The beneficial effects of the present invention are as follows: (1) Compared with the traditional electrode structure, except for the area that needs to be discharged, the rest of the electrode is vulcanized and sealed with insulating rubber, which greatly reduces the risk of material corrosion.

[0008] (2) Even if the electrode is corroded and leaks, it can be predicted and warned by water leakage detection to prevent the risk of internal circuit short circuit caused by high current discharge.

[0009] (3) The corrosion of the electrode will not cause damage to the cable. Only the electrode needs to be replaced, which greatly reduces the maintenance cost. Attached Figure Description

[0015] The technical solutions and advantages of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Referring to the accompanying drawings, the present invention provides a detachable electrode structure, including an electrode structure (100), an electrode sealing cylinder (200), a high-intensity acoustic eliminator sealing chamber (300), a positive electrode wire (201), a coaxial cable (202), a negative electrode wire (203), a large O-ring (204), and a medium O-ring (205). The positive electrode stud (7) is connected to the positive electrode needle (22) via the positive electrode wire (201); the negative electrode needle (26) is connected to the negative electrode screw (8) via the negative electrode wire (203). The positive and negative electrodes of the coaxial cable (202) are connected to the positive electrode needle (22) and the negative electrode needle (26), respectively. After connection, the coaxial cable (202) is wound around the outside of the cylinder (21), saving space. As an example, the insulating rubber used is neoprene rubber. The electrode structure (100) and the electrode sealing cylinder (200) are sealed by a small sealing ring (205). At the same time, the electrode structure (100) and the electrode sealing cylinder (200) are also sealed by a large sealing ring (204) to the high-intensity acoustic repulsion sealing chamber (300). This double sealing prevents the electrode structure (100) from being severely corroded or leaking water, allowing for quick and convenient replacement of the electrode structure (100) without the need to disassemble and adjust the high-intensity acoustic repulsion sealing chamber (300), saving time and making maintenance more convenient.

[0017] The positive electrode (201) and negative electrode (202) are connected to both the electrode structure (100) and the electrode sealing cylinder (200). The coaxial cable (203) contains two core cables and is connected to the electrode sealing cylinder (200). The coaxial cable (203) can minimize interference when a large current is applied. Since the coaxial cable (203) is placed inside the acoustic evacuation sealing chamber (300), the coaxial cable (203) does not need to be watertight.

[0018] In the electrode structure (100), the positive electrode (1) and the negative electrode (2) are coaxial to ensure uniformity during discharge. The negative electrode (2) and the negative electrode ring (3) are interference-fitted to ensure tightness of connection and reliability of conductivity. A positive electrode pad (4) is placed on the positive electrode (1), and a negative electrode pad (5) is placed on the negative electrode ring (3). Both the positive electrode pad (4) and the negative electrode pad (5) are made of insulating and elastic materials to reduce the damage to internal equipment vibration caused by instantaneous high voltage surge of the electrode. The positive electrode (1) is fastened to the sealing cover plate (6) by a positive electrode stud (7). The negative electrode ring (3), the terminal (9), and the sealing cover plate (6) are fixed by a negative electrode screw (8).

[0019] Neoprene rubber is wrapped between the positive electrode (1), the negative electrode (2), and the negative electrode ring (3), but only one side of the positive electrode (1) and the negative electrode (2) is left to contact seawater. In this way, the neoprene rubber can ensure that the non-discharge end of the positive and negative electrodes will not come into contact with seawater, thereby greatly reducing the possibility of corrosion and slowing down the corrosion rate of the positive electrode (1) and the negative electrode (2). In addition, it will not affect the contact area required for discharge between the positive electrode (1) and the negative electrode (2).

[0020] The electrode sealing cylinder (200) is mainly composed of a cylinder body (21), which is made of non-metallic material. The positive electrode needle (22) and the negative electrode needle (26) are sealed with the cylinder body (21) by a sealing O-ring (23), which not only ensures the normal power supply function of the positive electrode needle (22) and the negative electrode needle (26), but also prevents seawater leakage.

[0021] For the leak detection (24), it is sealed to the cylinder (21) by a small sealing ring (34). The small cover (31) is sealed to the leak detection positive electrode (32) and the leak detection negative electrode (33) by sealant (35). The leak detection (24) is located at the bottom of the cylinder. If the electrode structure (100) leaks seawater due to repeated discharges or seawater corrosion, the continuity between the leak detection positive electrode (32) and the leak detection negative electrode (33) of the leak detection (24) can be used to determine the leak. This effectively protects the electrode structure (100) from discharge in the event of water ingress, ensuring safety during use.

[0022] The electrode structure (100) is spatially isolated from the coaxial cable (203) by the electrode sealing cylinder (200), which effectively ensures that even if the electrode structure (100) leaks water, it will not enter the coaxial cable (203), thus effectively protecting the coaxial cable (203).

[0023] The positive electrode (1), negative electrode (2), sealing cover plate (6), positive electrode needle (22) and negative electrode needle (26) are all provided with grooves to ensure the reliability of the connection of neoprene rubber (10) or sealant (35).
