Description

Technical Field

[0001] This utility model relates to the field of seabed exploration technology, and in particular to a synthetic aperture ROV underwater reconnaissance device. Background Technology

[0002] The synthetic aperture ROV underwater reconnaissance system mainly consists of surface equipment (including control console, cable winch, deployment equipment, power supply system, etc.) and underwater equipment (including repeaters, the submersible body and the thrusters, cameras, video cameras, lighting, depth sensors, and operational equipment mounted on it). The submersible body moves underwater using thrusters and is equipped with observation equipment and operational equipment such as robotic arms, cutters, and cleaners. The underwater movement and operation of the ROV are controlled and monitored by operators on the surface mother ship. Repeaters reduce interference from cables on the submersible body's movement.

[0003] ROV underwater reconnaissance devices require human intervention but do not have issues with endurance or communication. They obtain power from the mother ship via cable and receive and transmit signals bidirectionally. Therefore, the cable is as crucial to the ROV as the "umbilical cord" is to the fetus. However, the harsh marine environment means that the connection between traditional ROV underwater reconnaissance devices and cables is usually rigid. Waves can easily cause the connection between the underwater reconnaissance device and the cable to break, thus affecting the detection operation. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a synthetic aperture ROV underwater reconnaissance device to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a synthetic aperture ROV underwater reconnaissance device, comprising a cable connector body and a cable plug body. The cable connector body has an assembly support on one side and a circuit connection cavity inside. The cable plug body includes a circuit connection head end, which slides within the circuit connection cavity. Positive and negative circuit strips are located above and below the inner cavity of the circuit connection cavity. Circuit contact pieces are located at the upper and lower ends of the circuit connection head end, and these contact pieces slide against the corresponding positive and negative circuit strips. External circuit connection seats are located on the upper and lower sides of the outer wall of the cable connector body, and external circuit connection heads are connected to these external circuit connection seats. The positive and negative circuit strips are connected to... The cable connector has a first electrical contact that extends to make electrical contact with an external circuit connector. A buffer cavity is provided inside the cable connector body on one side of the circuit connection cavity. The cable connector body also includes a threaded connector connected to the circuit connector end. The threaded connector is connected to a rigid cable portion, which extends through the middle of the buffer cavity. A flexible cable portion is connected to the outer end of the rigid cable portion. A watertight slide is provided on the outer wall of the rigid cable portion located in the buffer cavity. The watertight slide slides in conjunction with the inner cavity of the buffer cavity. Buffer springs are provided on both sides of the inner cavity of the buffer cavity located on the watertight slide, and the buffer springs abut against the watertight slide and the inner wall of the buffer cavity, respectively.

[0007] Furthermore, the inner wall of the circuit connection cavity is provided with a guide strip, and the two sides of the circuit connection head are provided with sliding grooves that cooperate with the guide strip. The guiding direction of the guide strip is consistent with the length arrangement direction of the positive and negative circuit strips.

[0008] Furthermore, the outer wall of the watertight slide is provided with 2-3 piston ring grooves, and piston rings are fitted in the piston ring grooves. The piston rings are slidably connected to the inner wall of the buffer cavity.

[0009] Furthermore, the circuit connection contact is an elastic contact that is snapped into the end of the circuit connector. One end of the circuit connection contact is connected to a second electrical contact, and the second electrical contact is in electrical contact with the threaded electrical connector.

[0010] Furthermore, the end of the circuit contact piece away from the second contact terminal is provided with an anti-disconnection elastic part, which is an elastic sheet with a "Z" shaped cross-section.

[0012] The beneficial effects of this utility model are:

[0013] 1. When the flexible cable is pulled, the present invention uses the buffer spring to buffer the pulling force on the watertight slide when the flexible cable is pulled. At the same time, the circuit connector slides in the circuit connection cavity. The circuit connector and the positive and negative circuit strips in the circuit connection cavity are always in sliding contact through the circuit connection contact piece to ensure the continuity of the circuit and effectively avoid the circuit break caused by the flexible cable being pulled. The connection is stable and effective.

[0014] 2. This utility model provides effective protection for electrical contacts by providing 2-3 piston rings on the outer wall of the watertight slide to prevent external water from entering the circuit connection cavity along the buffer cavity. In the circuit connection head, one end of the circuit connection contact is provided with an anti-breakage elastic part. The anti-breakage elastic part is an elastic sheet with a "Z" shaped bend in cross-section. Under the structural action of the anti-breakage elastic part, the circuit connection contact tends to bulge outward, ensuring a stable and effective electrical connection between the circuit connection contact and the positive and negative circuit strips.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] A synthetic aperture ROV underwater reconnaissance device includes a cable connector body 1 and a cable plug body 2. The cable connector body 1 has an assembly support 104 on one side for assembling and fixing the cable connector body. The cable connector body 1 has an internal circuit connection cavity 101. The cable plug body 2 includes a circuit connection head end 201, which slides within the circuit connection cavity 101. Positive and negative circuit strips 1011 are located above and below the internal cavity of the circuit connection cavity 101. Circuit contact pieces 2011 are located at the upper and lower ends of the circuit connection head end 201, and these contact pieces 2011 slide in contact with the corresponding positive and negative circuit strips 1011. External circuit connection seats 103 are located on the upper and lower sides of the outer wall of the cable connector body 1, and external circuit connection seats 103 are connected to external circuits. The connector 1031 has a positive and negative circuit strip 1011 connected to a first electrical contact 1012, which extends to make electrical contact with the external circuit connector 1031. This ensures that the circuit connector end 201 maintains a circuit connection while sliding within the circuit connection cavity 101. The inner wall of the circuit connection cavity 101 is provided with a guide strip 1013, and the circuit connector end 201 has sliding grooves 2014 on both sides that cooperate with the guide strip 1013. The guide strip 1013 is aligned with the length arrangement of the positive and negative circuit strips 1011, guiding the sliding direction of the circuit connector end 201 and preventing the circuit connector end 201 from rotating. This ensures that the circuit connection contact piece 2011 on the circuit connector end 201 remains in contact with the positive and negative circuit strips 1011.

[0025] The cable connector body 1 has a buffer cavity 102 inside and on one side of the circuit connection cavity 101. The cable plug body 2 also includes a threaded connector 202 connected to the circuit connection head 201. The threaded connector 202 is connected to a rigid cable part 203. The rigid cable part 203 extends through the middle of the buffer cavity 102. The outer end of the rigid cable part 203 is connected to a flexible cable part 204. The outer wall of the rigid cable part 203 located in the buffer cavity 102 is provided with a watertight slide 205. The watertight slide 205 slides in cooperation with the inner cavity of the buffer cavity 102. The inner cavity of the buffer cavity 102 and both sides of the watertight slide 205 are provided with buffer springs 1021. The buffer springs 1021 abut against the watertight slide 205 and the inner wall of the buffer cavity 102, respectively. When the flexible cable section 204 is pulled, the buffer spring 1021 acts on the watertight slide 205 to buffer the pulling force on the flexible cable section 204. At the same time, the circuit connection head end 201 slides in the inner cavity of the circuit connection cavity 101. The circuit connection head end 201 maintains sliding contact with the positive and negative circuit strips 1011 in the inner cavity of the circuit connection cavity 101 through the circuit connection contact piece 2011, ensuring the continuity of the circuit.

[0026] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: When the flexible cable section 204 is pulled, the buffer spring 1021 acts on the watertight slide 205 to buffer the pulling force on the flexible cable section 204. At the same time, the circuit connection head end 201 slides in the inner cavity of the circuit connection cavity 101. The circuit connection head end 201 maintains sliding contact with the positive and negative circuit strips 1011 in the inner cavity of the circuit connection cavity 101 through the circuit connection contact piece 2011, ensuring the continuity of the circuit and effectively avoiding circuit breakage caused when the flexible cable section 204 is pulled, resulting in a stable and effective connection.

[0027] Example 2

[0028] The outer wall of the watertight slide 205 has 2-3 piston ring grooves, and piston rings are fitted in the piston ring grooves. The piston rings are slidably connected to the inner wall of the buffer cavity 102 to prevent external water from entering the circuit connection cavity 101 along the buffer cavity 102, thus effectively protecting the electrical contacts. A sealing ring 105 is provided between the circuit connection cavity 101 and the buffer cavity 102, and the sealing ring 105 is tightly fitted to the outer wall of the rigid cable part 203, further improving the watertightness.

[0029] like Figure 3As shown, the circuit connection contact 2011 is an elastic contact that snaps into the circuit connector end 201. One end of the circuit connection contact 2011 is connected to a second electrical contact 2012, and the second electrical contact 2012 is in electrical contact with the threaded electrical connector 202. The end of the circuit connection contact 2011 away from the second electrical contact 2012 is provided with an anti-breakage elastic part 2013. The anti-breakage elastic part 2013 is an elastic sheet with a "Z" shaped bend in cross-section. Under the structural action of the anti-breakage elastic part 2013, the circuit connection contact 2011 tends to bulge outward, ensuring a stable and effective electrical connection between the circuit connection contact 2011 and the positive and negative circuit strips 1011.

[0030] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: This utility model provides effective protection for electrical contacts by providing 2-3 piston rings on the outer wall of the watertight slide 205 to prevent external water from entering the circuit connection cavity 101 along the buffer cavity 102; In the circuit connection head end 201, one end of the circuit connection contact piece 2011 is provided with an anti-breakage elastic part 2013, which is an elastic sheet with a "Z" shaped bend in cross-section.
