[0023] The utility model provides a ROV salvage bracket and an unmanned remote-controlled submersible, wherein the first cable and the second cable jointly bear the weight of the salvaged object.

Therefore, the portion of the first cable arranged along the first vertical beam is kept vertical due to the force, and no horizontal force is applied to the first vertical beam. The vertical force is borne by the first cable itself, and the force on the first vertical beam is very small. Similarly, the force on the second vertical beam is also very small. The first cable passes through one end of the horizontal beam, and the second cable passes through the other end of the horizontal beam. The two ends of the horizontal beam only bear the horizontal force of the first cable and the horizontal force of the second cable.

[0038] like Figure 1 As shown, this embodiment provides an unmanned remote-controlled submersible. The unmanned remote-controlled submersible includes an ROV body and an ROV salvage bracket arranged on the ROV body.

[0039] like Figure 1As shown, the ROV body includes a shell 101 and a bearing head 102 arranged on the top of the shell 101. Specifically, the bearing head 102 is connected with a bearing rope 500, and the unmanned remotely operated submersible is pulled up and down by the bearing rope 500 to dive or float.

[0040] Combination Figure 1 and Figure 2 As shown, the ROV salvage support includes a horizontal beam 200, a first vertical beam 300, a second vertical beam 400, a first cable 303, and a second cable 403. The upper end of the first vertical beam 300 is connected to one end of the horizontal beam 200, and the upper end of the second vertical beam 400 is connected to the other end of the horizontal beam 200. The horizontal beam 200 is configured to be arranged on the top of the housing 101, the first vertical beam 300 is configured to be arranged on one side of the housing 101 in the horizontal direction, and the second vertical beam 400 is configured to be arranged on the other side of the housing 101 in the horizontal direction. The upper ends of the first cable 303 and the second cable 403 are both configured to be connected to the bearing head 102. The first cable 303 passes through one end of the horizontal beam 200 and extends downward along the first vertical beam 300 to the bottom of the first vertical beam 300. The second cable 403 passes through the other end of the horizontal beam 200 and extends downward along the second vertical beam 400 to the bottom of the second vertical beam 400. The lower end of the first cable 303 and the lower end of the second cable 403 are both configured to be connected to the salvaged object 700, the horizontal component of the tension acting on the upper end of the first cable 303 and the horizontal component of the tension acting on the upper end of the second cable 403 are balanced with each other, and the horizontal component of the tension acting on the lower end of the first cable 303 and the horizontal component of the tension acting on the lower end of the second cable 403 are balanced with each other.

[0041] The horizontal beam 200 refers to a structural beam extending in a straight line in the horizontal direction, and the first vertical beam 300 and the second vertical beam 400 refer to structural beams extending in a straight line in the vertical direction. The shear strength and compressive strength of the horizontal beam 200, the first vertical beam 300 and the second vertical beam 400 are designed according to the adaptability of the salvage load. In this embodiment, the length of the horizontal beam 200 is the same as the width of the shell 101, and the length of the first vertical beam 300 and the second vertical beam 400 is the same as the height of the shell 101.

[0042] The first cable 303 and the second cable 403 can both be steel cables, which have high structural strength and are strong and durable.

[0043] In the unmanned remote-controlled submersible provided in this embodiment, the first cable 303 and the second cable 403 jointly bear the weight of the salvaged object 700. Since the horizontal force on the lower end of the first cable 303 and the horizontal force on the lower end of the second cable 403 are balanced, the horizontal force on the upper end of the first cable 303 and the horizontal force on the upper end of the second cable 403 are balanced, therefore, a portion of the first cable 303 arranged along the first vertical beam 300 is kept vertical due to the force, and no horizontal force is applied to the first vertical beam 300, while the vertical force is borne by the first cable 303 itself, and the force on the first vertical beam 300 is very small. Similarly, the force on the second vertical beam 400 is also very small. The first cable 303 passes through one end of the horizontal beam 200, and the second cable 403 passes through the other end of the horizontal beam 200. The two ends of the horizontal beam 200 only bear the horizontal force of the first cable 303 and the horizontal force of the second cable 403. Therefore, the lateral force of the horizontal beam 200 is also significantly smaller. Through the guidance of the first cable 303 and the second cable 403 by the horizontal beam 200, the first vertical beam 300 and the second vertical beam 400, the gravity of the salvaged object 700 is distributed on the first cable 303 and the second cable 403, and is concentratedly transmitted to the bearing head 102 through the first cable 303 and the second cable 403. The force acting on the horizontal beam 200, the first vertical beam 300 and the second vertical beam 400 is significantly reduced, thereby protecting the outer shell 101 from being damaged by the huge external pulling force.

[0044] Optionally, a first limiting portion is arranged on the first vertical beam 300 along its length direction, and the first cable 303 passes through the first limiting portion, and a second limiting portion is arranged on the second vertical beam 400 along its length direction, and the second cable 403 passes through the second limiting portion. In other words, the first limiting portion is used to limit the first cable 303, so that the first cable 303 is kept at the first vertical beam 300, and the second limiting portion is used to limit the second cable 403, so that the second cable 403 is kept at the second vertical beam 400, so as to avoid the first cable 303 and the second cable 403 from being offset and affecting the stress of the overall structure, thereby avoiding damage to the ROV body and maintaining a high salvage capability.

[0045] like Figure 2 As shown, specifically, the first limiting portion is a first limiting groove 301 that runs through the length direction of the first vertical beam 300, and the first cable 303 runs through the first limiting groove 301 along the length direction of the first limiting groove 301. The first cable 303 is limited by the first limiting groove 301, the structure is simple, the first cable 303 is easy to arrange, and the limiting effect is good.

[0046] The second limiting portion is a second limiting groove that runs through the length direction of the second vertical beam 400. The first cable 303 passes through the first limiting groove 301 along the length direction of the first limiting groove 301, and the second cable 403 passes through the second limiting groove along the length direction of the second limiting groove. The second cable 403 is limited by the second limiting groove, which has a simple structure, is convenient for arranging the second cable 403, and has a good limiting effect.

[0047] In this embodiment, the first vertical beam 300 and the second vertical beam 400 can both be channel steels, and the grooves of each channel steel directly serve as the first limiting groove 301 and the second limiting groove. Moreover, the channel steel has high structural strength and is not easily damaged.

[0048] Optionally, the ROV salvage support further includes a first stopper (not shown) disposed on the first vertical beam 300, the two ends of the first stopper are respectively connected to the two side walls of the first limiting groove 301, and the first cable 303 is located between the first stopper and the first limiting groove 301. The first stopper cooperates with the first limiting groove 301 to completely limit the first cable 303, and the limiting effect of the first cable 303 is good.

[0049] The ROV salvage support also includes a second stopper (not shown) disposed on the second vertical beam 400, the two ends of the second stopper are respectively connected to the two side walls of the second limiting groove, and the second cable 403 is located between the second stopper and the second limiting groove. The second stopper cooperates with the second limiting groove to completely limit the second cable 403, and the limiting effect of the second cable 403 is good.

[0050] In this embodiment, the first stopper and the second stopper can both be cable ties. The channel walls on both sides of the channel steel are provided with through holes, and the cable ties pass through the through holes and are connected to the channel steel.

[0051] like Figure 2 As shown, optionally, the horizontal beam 200 is provided with a third limiting groove 201 that runs through along its length direction, and the first cable 303 starts from the load-bearing head 102 and passes through the third limiting groove 201 to enter the first limiting groove 301, and the second cable 403 starts from the load-bearing head 102 and passes through the third limiting groove 201 to enter the second limiting groove. The third limiting groove 201 limits the direction of the first cable 303 and the second cable 403 to avoid the imbalance of force in the horizontal direction caused by the deviation. The horizontal beam 200 is a channel steel with high structural strength, and the groove of the channel steel serves as the third limiting groove 201.

[0052] Preferably, the first vertical beam 300 and the second vertical beam 400 are symmetrical about the vertical axis, the first cable 303 and the second cable 403 are symmetrical about the vertical axis, the horizontal beam 200 is symmetrical about the vertical axis, and the bearing head 102 is located on the vertical axis. In other words, the ROV salvage bracket is symmetrical about the vertical axis as a whole, so that the horizontal components of the first cable 303 and the second cable 403 are mutually balanced, significantly reducing the force directly acting on the ROV body.

[0053] In this embodiment, the ROV salvage bracket further includes a hanging member 600, the lower end of the first cable 303 and the lower end of the second cable 403 are both connected to the hanging member 600, the hanging member 600 is located on the vertical axis, and the hanging member 600 is configured to be connected to the salvage 700. Specifically, the hanging member 600 is a swivel, which limits the lower ends of the first cable 303 and the second cable 403 on the vertical axis, so as to achieve the balance of the horizontal force component of the first cable 303 and the horizontal force component of the second cable 403. Further, in order to facilitate the connection of the salvage 700, a salvage hook is also connected under the swivel, and the salvage hook is connected to the salvage 700.

[0054] Combination Figure 1 and Figure 2 As shown, in order to realize reliable connection between the ROV salvage bracket and the ROV body, optionally, the ROV salvage bracket further includes a plurality of first connecting members 302 arranged along the first vertical beam 300, the first connecting members 302 are bolted to the first vertical beam 300, and the first connecting members 302 are configured to be bolted to the housing 101. The ROV salvage bracket further includes a plurality of second connecting members 402 arranged along the second vertical beam 400, the second connecting members 402 are bolted to the second vertical beam 400, and the second connecting members 402 are configured to be bolted to the housing 101. In this embodiment, the first connecting members 302 and the second connecting members 402 are both fixed angle irons, which are convenient to connect.

In other words, the first beam 202 and the second beam 203 are two independent sections, which are convenient for assembly and fixation on the shell 101 of the ROV body. The lengths of the first beam 202 and the second beam 203 are equal, so that the bearing head 102 is completely centered on the horizontal beam 200.

[0056] The unmanned remote-controlled submersible and its ROV salvage bracket provided in this embodiment are provided with horizontal beams 200 on both sides of the bearing head 102 at the top of the shell 101, the first vertical beam 300 and the second vertical beam 400 are respectively fixed on both sides of the horizontal beam 200, and the first cable 303 and the second cable 403 are arranged, so as to transfer and concentrate the force point on the bearing head 102, and the bearing head 102 is pulled by the bearing rope 500, and the components of the first cable 303 and the second cable 403 in the horizontal direction offset each other. The shell 101 and other components (buoyancy materials) of the ROV body are protected, and the salvage bearing capacity of the unmanned remote-controlled submersible is enhanced. The structure of the ROV salvage bracket is simple and reliable, and it is convenient to disassemble and assemble, and it is easy to switch according to the operation requirements. The ROV salvage bracket has a simple structure and has little effect on the weight, volume and appearance of the unmanned remote-controlled submersible itself.
