In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0046] like Figure 1 and Figure 2 As shown, an underwater equipment capturing device 100 provided by an embodiment of the utility model is configured on a navigation device and is used to capture underwater equipment; specifically, the underwater equipment is connected to a cable 8 of an automatic winch on the navigation device, and the automatic winch adjusts the length of the cable 8 to achieve the deployment and recovery of the underwater equipment; the underwater equipment capturing device of this embodiment can fix the recovered underwater equipment, improve the stability of the underwater equipment, and reduce the possibility of the cable 8 and the underwater equipment being broken during recovery; the following is an explanation through a specific implementation method:

[0047] The underwater equipment capturing device 100 of this embodiment includes: a slide rail 1, a fixing member 2, a sliding member 3, an elastic member 4 and a driving member 5;

[0048] The slide rail 1 is used to be arranged on the navigation equipment body. Optionally, the length direction of the slide rail 1 is parallel to the length direction of the navigation equipment body, so that the length direction of the slide rail 1 is the same as the navigation direction of the navigation equipment body, which is conducive to the deployment of the underwater equipment;

[0049] The fixing member 2 is arranged at one end of the slide rail 1; it can be understood that the fixing member 2 is used to cooperate with the sliding member 3 to form a capture opening 6, so that when the guide member 7 of the underwater device enters the capture opening 6, the fixing member 2 and the sliding member 3 jointly limit the guide member 7 to fix the underwater device; specifically, the fixing member 2 can be in the shape of an axis structure, such as a fixed axis;

[0050] The sliding member 3 is arranged at the other end of the slide rail 1, and a capture opening 6 for the guide member 7 of the underwater device to pass through is formed between the sliding member 3 and the fixing member 2; it can be understood that the sliding member 3 is used to cooperate with the fixing member 2 to form the capture opening 6, specifically, the sliding member 3 and the fixing member 2 are respectively arranged at the two ends of the slide rail 1, and the sliding member 3 and the fixing member 2 are arranged relative to each other, so that the capture opening 6 can be formed between the two, and when the guide member 7 of the underwater device enters the capture opening 6, the sliding member 3 and the fixing member 2 jointly limit the guide member 7 to fix the underwater device; specifically, the shape of the sliding member 3 can be an axis structure, such as a sliding axis;

[0051] The elastic member 4 connects the fixed member 2 and the sliding member 3, and is used to drive the sliding member 3 to move on the slide rail 1 in a direction close to the fixed member 2, so that the capture opening 6 shrinks; here, it can be understood that the sliding member 3 is slidably arranged on the slide rail 1, so that the sliding member 3 can slide on the slide rail 1, and the elastic member 4 connects the fixed member 2 and the sliding member 3. In this embodiment, the fixed member 2 is fixedly arranged on the slide rail 1, and the sliding member 3 is slidably arranged on the slide rail 1, so that the elastic force of the elastic member 4 is used to drive the sliding member 3 to move in a direction close to the fixed member 2; it needs to be further explained that when the guide member 7 of the underwater equipment enters the capture opening 6, the elastic force of the elastic member 4 drives the sliding member 3 to move in a direction close to the fixed member 2, so that the capture opening 6 shrinks to limit the guide member 7, thereby fixing the underwater equipment;

[0052] The driving member 5 is used to drive the sliding member 3 to move in a direction away from the fixing member 2 to open the capture opening 6. Here, it can be understood that when deploying underwater equipment, the guide member 7 needs to be released from the capture opening 6; specifically, the driving member 5 is used to drive the sliding member 3 to move, and the sliding member 3 moves in a direction away from the fixing member 2, that is, the capture opening 6 is enlarged, at this time, the fixing member 2 and the sliding member 3 no longer limit the guide member 7, and the automatic winch releases the cable 8 to deploy the underwater equipment; specifically, the driving member 5 can be in the shape of a push rod.

[0053] The working principle of the underwater equipment capturing device 100 provided in this embodiment is as follows:

[0054] Recovering underwater equipment: The cable 8 of the automatic winch is arranged through the capture opening 6, and the cable 8 is connected to the underwater equipment and a guide 7 is provided at the connection between the two; when the navigation equipment recovers the underwater equipment, the automatic winch recovers the cable 8, and the cable 8 drags the underwater equipment toward the capture opening 6. When the cable 8 drags the guide 7 into the capture opening 6, the guide 7 squeezes the sliding member 3 to force the sliding member 3 to move in a direction away from the fixing member 2. When the guide 7 completely enters the capture opening 6, the sliding member 3 moves in a direction close to the fixing member 2 under the elastic force of the elastic member 4, that is, the sliding member 3 and the fixing member 2 jointly limit the guide 7, so that the underwater equipment is fixed relative to the navigation equipment;

[0055] Deploying underwater equipment: The driving member 5 drives the sliding member 3 to move in a direction away from the fixing member 2, so that the distance between the sliding member 3 and the fixing member 2 is enlarged, so that the capture opening 6 is opened. At this time, the fixing member 2 and the sliding member 3 no longer limit the guide member 7, that is, the guide member 7 can escape from the capture opening 6. At the same time, the automatic winch releases the cable 8 to realize the deployment of the underwater equipment.

[0056] By adopting the above technical solution:

[0057] First, the capture opening 6 formed between the fixing member 2 and the sliding member 3 can limit the guide member 7 of the underwater device under the elastic force of the elastic member 4, thereby fixing the underwater device and reducing the tension required at the connection between the underwater device and the cable 8 of the automatic winch, that is, reducing the possibility of the underwater device and the cable 8 being broken;

[0058] Secondly, the elastic member 4 can drive the sliding member 3 to automatically approach the fixing member 2, thereby automatically capturing the underwater equipment and improving the probability of safe recovery;

[0059] Finally, the sliding member 3 and the fixing member 2 are connected via the elastic member 4, so that the capture opening 6 therebetween can adapt to guide members 7 of different sizes, and thus can be adapted to capture underwater equipment of different types.

[0060] In one embodiment, the driving member 5 is provided with an abutment rod 51 for abutting the sliding member 3, and the position of the abutment rod 51 on the slide rail 1 is adjustable, so that the size of the capture opening 6 is adjustable; when the driving member 5 drives the abutment rod 51 to move in a direction away from the fixed member 2, the abutment rod 51 pushes the sliding member 3 to move in a direction away from the fixed member 2, so that the capture opening 6 is expanded; when the driving member 5 drives the abutment rod 51 to move in a direction close to the fixed member 2, the sliding member 3 moves in a direction close to the fixed member 2 under the elastic force of the elastic member 4, so that the capture opening 6 is reduced.

[0061] Here, it can be understood that the driving member 5 is provided with an abutment rod 51, and the abutment rod 51 abuts and cooperates with the sliding member 3, so that the abutment rod 51 and the sliding member 3 abut or separate in different states; specifically, when the guide member 7 enters the capture opening 6, the sliding member 3 is passively moved in a direction away from the fixing member 2 under the squeezing of the guide member 7, and the sliding member 3 is separated from the abutment rod 51; and when the sliding member 3 needs to actively move in a direction away from the fixing member 2 to open the capture opening 6, the driving member 5 drives the abutment rod 51 to move, and the abutment rod 51 pushes the sliding member 3 to move in a direction away from the fixing member 2.

[0062] It needs to be further explained that the abutment rod 51 can adjust its position relative to the slide rail 1 as the driving member 5 moves, thereby adjusting the size of the capture opening 6; specifically, the sliding member 3 moves in a direction close to the fixed member 2 under the elastic force of the elastic member 4, and stops moving when the sliding member 3 moves to abut against the abutment rod 51. At this time, the distance between the sliding member 3 and the fixed member 2 is the size of the capture opening 6, and the size of the capture opening 6 can be adjusted by adjusting the position of the abutment rod 51 relative to the slide rail 1.

[0063] By adopting the above technical solution, the applicability of the underwater equipment capturing device 100 is improved.

[0064] Please also read Figure 3 In one embodiment, the slide rail 1 includes a first slide rail unit 11 and a second slide rail unit 12 spaced parallel to the first slide rail unit 11, a first slide groove 13 slidably matched with the sliding member 3 is formed between the first slide rail unit 11 and the second slide rail unit 12, and a second slide groove 14 slidably matched with the driving member 5 is provided on the first slide rail unit 11 and the second slide rail unit 12, the second slide groove 14 is connected to the first slide groove 13, and the length direction of the second slide groove 14 is the same as the length direction of the first slide groove 13.

[0065] Here, it can be understood that the first slide rail unit 11 and the second slide rail unit 12 are arranged opposite to each other in the upper and lower parts, and a first slide groove 13 that can accommodate one end of the sliding member 3 is formed therebetween, one end of the sliding member 3 is accommodated in the first slide groove 13, and can slide along the length direction of the first slide groove 13 under the groove wall limit of the first slide groove 13; the first slide rail unit 11 and the second slide rail unit 12 are both provided with a second slide groove 14, the two ends of the driving member 5 are respectively accommodated in the second slide groove 14 of the first slide rail unit 11 and the second slide groove 14 of the second slide rail unit 12, and can slide along the length direction of the second slide groove 14 under the groove wall limit of the two second slide grooves 14; it needs to be further explained that the second slide groove 14 is connected to the first slide groove 13, so that the abutment rod 51 and the sliding member 3 are easy to cooperate with.

[0066] By adopting the above technical solution, the abutting rod 51 and the sliding member 3 are easy to cooperate with each other.

[0067] Please also read Figure 4 In one embodiment, the driving member 5 includes a first driving member unit 52 and a second driving member unit 53 spaced parallel to the first driving member unit 52, the first driving member unit 52 is arranged on the side of the first slide rail unit 11 away from the second slide rail unit 12, the second driving member unit 53 is arranged on the side of the second slide rail unit 12 away from the first slide rail unit 11, and the abutment rod 51 is arranged between the first driving member unit 52 and the second driving member unit 53.

[0068] Here, it can be understood that the first driving member unit 52 and the second driving member unit 53 are arranged opposite to each other in the upper and lower parts, and the abutment rod 51 is arranged between the first driving member unit 52 and the second driving member unit 53, and the two ends of the abutment rod 51 are respectively connected to the first driving member unit 52 and the second driving member unit 53, thereby improving the stability of the abutment rod 51 when pushing the sliding member 3.

[0069] By adopting the above technical solution, the stability of the abutment rod 51 during movement is improved.

[0070] In one embodiment, the underwater equipment capturing device 100 includes two slide rails 1 arranged opposite to each other, two ends of the fixing member 2 are respectively connected to the two slide rails 1 , and two ends of the sliding member 3 are respectively connected to the two slide rails 1 .

[0071] Here, it can be understood that the two slide rails 1 correspond to the two ends of the fixed member 2 and the sliding member 3 respectively, so that the two slide rails 1 respectively limit the sliding direction of the sliding member 3, thereby improving the stability of the sliding member 3 when moving.

[0072] By adopting the above technical solution, the stability of the sliding member 3 during movement is improved.

[0073] In one embodiment, the underwater equipment capturing device 100 includes two driving members 5 arranged opposite to each other, and the two driving members 5 are respectively connected to two ends of the sliding member 3 .

[0074] Here, it can be understood that the two driving members 5 push the two ends of the sliding member 3 synchronously, thus further improving the stability of the driving members 5 when moving.

[0075] By adopting the above technical solution, the stability of the driving member 5 during movement is improved.

[0076] In one embodiment, the underwater device capturing apparatus 100 further includes a power output member 9 for driving the driving member 5 to move, and a driving end of the power output member 9 is connected to two driving members 5 .

[0077] By adopting the above technical solution, the power output member 9 can drive the two driving members 5 to move at the same time, thus saving the number of power components.

[0078] Please refer again Figure 3 In one embodiment, the fixing member 2 is provided with a first rotating sleeve 21 , which can rotate freely around the fixing member 2 , and the sliding member 3 is provided with a second rotating sleeve 31 , which can rotate freely around the sliding member 3 .

[0079] Here, it can be understood that when the guide member 7 enters the capture opening 6, sliding friction will occur with the fixed member 2 and the sliding member 3. Therefore, a first rotating sleeve 21 is provided on the fixed member 2 and a second rotating sleeve 31 is provided on the sliding member 3. In this way, when the guide member 7 enters the capture opening 6, it can drive the first rotating sleeve 21 and the second rotating sleeve 31 to rotate around the axis, thereby reducing the friction of the guide member 7 when entering the capture opening 6, thereby reducing the resistance during entry, and improving the smoothness of the guide member 7 entering the capture opening 6.

[0080] By adopting the above technical solution, the smoothness of the guide member 7 entering the capture opening 6 is improved.

[0081] In the second aspect, a navigation device is provided, including a navigation device body, an underwater device and the underwater device capture device 100, wherein the underwater device capture device 100 is installed on the navigation device body, and the underwater device is provided with a guide member 7 cooperating with the underwater device capture device 100.

[0082] Here, it can be understood that the navigation equipment of this embodiment includes unmanned ships and manned ships.

[0083] It needs to be further explained that the navigation equipment of this embodiment solves the problem of low success rate of recovery of existing towing systems; solves the risk of losing the side scan sonar due to cable or rope breakage during the cooperation between the towing system and the automatic winch; solves the speed mismatch problem during the retraction and release of the swing cylinder of the towing system and the servo motor of the automatic winch; solves the problem of underwater equipment storage during the high-speed unmanned boat cruising; in addition, this embodiment realizes modular design, which is easy to quickly replace accessories; realizes no underwater sensor, and reduces the probability of failure of underwater equipment recovery due to water ingress to the sensor; the navigation equipment of this embodiment relies on the spring mechanism of the slide rail 1 during the recovery of underwater equipment to achieve automatic capture. Improve the probability of safe recovery.

[0084] By adopting the above technical solution, on the basis of having the advantages of the above underwater equipment capturing device 100, the navigation equipment of this embodiment also has the advantage of a high success rate in capturing underwater equipment.

[0085] Please refer again Figure 1 In one embodiment, the guide member 7 is a conical guide member 7, and the guide member 7 has a top end 71 and a bottom end 72 in the guiding direction, the diameter of the top end 71 is smaller than the distance between the fixed member 2 and the sliding member 3 when the capture opening 6 is in a locked state, and the diameter of the bottom end 72 is larger than the distance between the fixed member 2 and the sliding member 3 when the capture opening 6 is in a locked state.

[0086] Here, it can be understood that the guiding direction of the guide member 7 is the direction of entering the capture opening 6, and the top end 71 of the guide member 7 first enters the capture opening 6. The sliding member 3 is arranged close to the fixing member 2 under the action of the elastic member 4, and the capture opening 6 between the two is contracted to form a locked state. Therefore, the diameter of the top end 71 is smaller than the distance between the capture openings 6, so that the top end 71 can enter the capture opening 6, and in the process of entering, the guide member 7 as a whole squeezes the sliding member 3 to expand the capture opening 6, so that the entire guide member 7 enters the capture opening 6. When the bottom end 72 of the guide member 7 also completely enters the capture opening 6, the sliding member 3 moves along the direction close to the fixing member 2 under the elastic force of the elastic member 4, that is, the capture opening 6 is contracted again to form a locked state, and the limiting guide member 7 is thereby realized to fix the underwater equipment.

[0087] By adopting the above technical solution, the position limiting of the guide member 7 and the fixing of the underwater equipment are achieved.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
