The support body frame 1 is used for fixed mounting, for example, on the hull 9 (see fig. 12) to fix the underwater equipment retracting device 100 at a desired position. The form of the support body frame 1 is not limited so that the linkage assembly 3, the power assembly 2 and the underwater equipment 8 can be accommodated after the underwater equipment 8 is recovered.

And, the number of the linkage assembly 3, the power assembly 2 and the underwater equipment 8 can be one or more. For example, in the present embodiment, the number of the power assemblies 2 is two, each power assembly 2 is used for connecting one underwater device 8, and the two underwater devices 8 may be the same or different, please refer to fig. 7 to 10 in combination. Therefore, the practicability of the underwater equipment retracting device 100 can be improved, and different underwater detection requirements can be met.

As shown in fig. 2 and 3, the number of the hatches 12 may be two, and the hatches are respectively connected to one linkage assembly 3, at this time, the power assemblies 2, the linkage assemblies 3, the underwater devices 8 and the hatches 12 correspond to each other one by one, and each hatche 12 can be opened and closed corresponding to the underwater device 8 to be deployed and recovered.

Of course, in other alternative embodiments, the number of hatches 12 may be one, i.e. the hatches 12 are open, allowing both subsea equipment 8 to be raised and lowered. At this time, the number of the linkage assemblies 3 can be one, and the linkage assemblies are driven by one of the power assemblies 2 to close the cabin door 12; the number of the linkage assemblies 3 can also be two, the two linkage assemblies 3 are simultaneously connected to the cabin door 12 and correspondingly driven by the two power assemblies 2, and the two power assemblies 2 simultaneously act to drive the two linkage assemblies 3 to act simultaneously, so that the cabin door 12 is closed.

Referring to fig. 1, 3 and 5, in one embodiment, the fixed frame 11 includes a lower chamber 112 and two upper chambers 111 respectively communicating with the lower chamber 112, the hatch 12 is disposed at the bottom of the lower chamber 112, and the two upper chambers 111 and the lower chamber 112 are respectively provided with two power assemblies 2 and two linkage assemblies 3, and referring to fig. 2 and 4, the underwater equipment 8 extends from the lower chamber 112 and is retracted into the lower chamber 112.

Referring to fig. 4, 5 and 7, in an embodiment, the power assembly 2 includes a telescopic power rod 21, an upper end of the telescopic power rod 21 is fixedly connected to the fixed frame 11, a lower end of the telescopic power rod 21 is used for connecting the underwater equipment 8, and the telescopic power rod 21 can extend and shorten in a vertical direction, so as to drive the underwater equipment 8 to lift. The form of the telescopic power rod 21 is not limited, and may be a pneumatic rod, a hydraulic rod, or an electric rod.

Specifically, as shown in fig. 5 and fig. 7 to 10, the telescopic power lever 21 includes a fixed shaft 211 and a sliding shaft 212 coaxially connected, and the sliding shaft 212 is slidably inserted into and removed from the fixed shaft 211. As such, when the sliding shaft 212 slides along the inside of the fixed shaft 211 by pneumatic power, hydraulic power, or electric power, the total length of the fixed shaft 211 and the sliding shaft 212 changes, that is, the telescopic power rod 21 as a whole achieves elongation and contraction.

In one embodiment, referring to fig. 4, 5 and 7, the power assembly 2 further includes a fixed guide sleeve 23 fixedly disposed in the fixed frame 11, and the telescopic power rod 21 slides through the fixed guide sleeve 23. Specifically, the fixed guide sleeve 23 is disposed at a lower position in the upper cabin 111. The fixed guide sleeve 23 is used for limiting the telescopic power rod 21 in the horizontal direction, so that the telescopic power rod 21 is always kept telescopic in the vertical direction, and the telescopic power rod 21 is prevented from deviating to influence the lifting of the underwater equipment 8.

Referring to fig. 6 and 11, in one embodiment, the linkage assembly 3 includes a linkage rod 31 and an upper limiting block 32 formed on the linkage rod 31, the linkage rod 31 is connected between the fixed frame 11 and the door 12, the linkage rod 31 can move downward in a vertical direction, so that the door 12 opens downward after being flipped, and the power assembly 2 can also push the upper limiting block 32 to ascend, so that the linkage rod 31 is lifted, and the door 12 closes after being flipped reversely.

Specifically, as shown in fig. 5 and 7, the power assembly 2 further includes a limit plate 22 connected to the telescopic power rod 21 and extending and retracting along with the telescopic power rod to be raised and lowered, and the limit plate 22 is located below the upper limit block 32. Therefore, when the limiting plate 22 descends along with the extension of the telescopic power rod 21, the upper limiting block 32 of the linkage rod 31 also descends along with the limiting plate 22, and thus the linkage rod 31 can move downwards under the action of self gravity. When the limit plate 22 moves upwards along with the shortening of the telescopic power rod 21, the limit plate 22 drives the upper limit block 32 and the linkage rod 31 to move upwards, so that the cabin door 12 is closed. Through setting up the connected mode between gangbar 31 and the fixed support body 11, can confirm the biggest displacement volume of gangbar 31 in the vertical direction, the displacement volume that gangbar 31 can take place in the vertical direction can be greater than, be less than or equal to the biggest flexible volume of flexible power rod 21.

In the present embodiment, the displacement amount of the linkage rod 31 in the vertical direction is smaller than the maximum telescopic amount of the telescopic power rod 21, which may make: when the underwater equipment 8 is laid, when the telescopic power rod 21 extends, the limiting plate 22 and the linkage rod 31 descend, when the cabin door 12 is opened in place, the linkage rod 31 does not descend any more, the upper limiting block 32 is positioned above the limiting plate 22, the telescopic power rod 21 cannot be influenced to continue to extend, and the underwater equipment 8 can continue to descend into the water body; when the underwater equipment 8 is recovered, when the telescopic power rod 21 is shortened, the underwater equipment 8 of the limiting plate 22 rises, and only when the telescopic power rod 21 is shortened to a position where the underwater equipment 8 is close to the cabin door 12, the limiting plate 22 is abutted against the upper limiting block 32, so that the telescopic power rod 21 is continuously shortened, and then the cabin door 12 can be driven to be closed.

Referring to fig. 11, the linkage rod 31 includes a main rod body 311, a first hinge rod body 312 and a second hinge rod body 313, wherein one end of the first hinge rod body 312 is hinged to the inner sidewall of the fixed frame 11, the other end of the first hinge rod body 312 is hinged to the upper end of the main rod body 311, one end of the second hinge rod body 313 is hinged to the lower end of the main rod body 311, and the other end of the second hinge rod body 313 is hinged to the door 12. Thus, after the first hinge rod 312 rotates downward, the main rod 311 is allowed to move downward, and then the second hinge rod 313 is driven to rotate downward, and finally, the door 12 is turned downward and opened, otherwise, the door 12 is turned upward and closed. The upper limit block 32 is formed on the main lever body 311.

Further, the first and second hinge rods 312 and 313 have the same length and are parallel to each other, so that the horizontal displacement of the upper and lower ends of the main rod 311 caused by the hinge rotation of the first and second hinge rods 312 and 313 is always the same, that is, the main rod 311 can always keep vertical during the movement of the main rod 311 along with the first and second hinge rods 312 and 313.

Further, the first hinge rod 312 is hinged to the fixed frame 11 in a vertical plane, and the second hinge rod 313 is hinged to the door 12 in a vertical plane.

Thus, the vertical displacement and the horizontal displacement of the stopper rod are determined by the lengths of the first and second hinge rod bodies 312 and 313 and the rotatable angle.

In other alternative embodiments, at least one of the first and second hinge rods 312 and 313 may be replaced by a flexible connector (not shown). The flexible connecting member only limits the maximum displacement of the main rod body 311 in the vertical direction, and can freely deform in the horizontal direction, thereby being capable of adapting to the displacement of the main rod body 311 in the horizontal and vertical directions. The flexible connecting piece can be specifically a rope, a spring and the like.

The upper limit block 32 may be a protrusion structure integrally formed with the main lever body 311, or may be a structure additionally fixed to the main lever body 311, which is not particularly limited. In an alternative embodiment, the upper limiting block 32 is detachably fixed to the main rod 311, which is advantageous in that the position of the upper limiting block 32 on the main rod 311 can be set according to specific needs, for example, to adapt to different forms and lengths of the supporting body frame 1, different lifting and lowering displacement requirements of the underwater device 8, and the like, thereby improving the adaptability of the linkage assembly 3.

Referring to fig. 11, in an embodiment, the limiting plate 22 is formed with an elongated sliding slot 220, and the main rod 311 of the linkage rod 31 slides in the sliding slot 220. The extending direction of the sliding slot 220 is consistent with the displacement direction of the main rod body 311 in the horizontal plane, so that the horizontal displacement of the main rod body 311 is guided by the sliding slot 220 in the moving process, and is not hindered by other positions of the limiting plate 22.

Further, referring to fig. 11, in an embodiment, the linkage assembly 3 further includes a lower limiting block 33 formed on the main rod body 311 of the linkage rod 31, and an elastic member 34 disposed on the main rod body 311 and located between the lower limiting block 33 and the limiting plate 22. This has the advantage that, when the length of the telescopic power rod 21 approaches its maximum length, the distance between the limit plate 22 and the lower limit block 33 decreases, thereby compressing the elastic member 34, and the pressure generated by the elastic member 34 acts on the lower limit block 33, and further acts on the main rod body 311 and the door 12, so that the door 12 maintains a downward-turned open state, and thus, even in high sea conditions, the door 12 does not shake and collide with the telescopic power rod 21; conversely, when the underwater equipment 8 is recovered, the elastic member 34 can prevent the cabin door 12 from being closed in advance due to shaking, so that the underwater equipment 8 cannot enter the fixing frame body 11.

Similarly, the lower limit block 33 may be a protrusion structure integrally formed with the main lever body 311, or may be a structure additionally fixed to the main lever body 311, which is not particularly limited. In an alternative embodiment, the lower limiting block 33 is detachably fixed to the main rod 311, which is advantageous in that the position of the lower limiting block 33 on the main rod 311 can be set according to specific needs, for example, to adapt to different forms and lengths of the supporting body frame 1, different lifting displacements of the underwater device 8, and the like, thereby improving the adaptability of the linkage assembly 3.

The elastic element 34 may be a spring, which is sleeved on the main rod 311.

Referring to fig. 3 and 11, in one embodiment, the door 12 includes two panels 120 (only one panel 120 is shown in fig. 11), and the edges of the two panels 120 that are far away from each other are respectively close to the edge of the lower cabin 112. In each linkage assembly 3, the number of the linkage rods 31 and the chutes 220 is four, and the chutes 220 are two by two in one set and extend oppositely, so that the horizontal displacement directions of every two linkage rods 31 are opposite, that is, every two linkage rods 31 with the same horizontal displacement direction are correspondingly hinged with one door panel 120 and drive the one door panel 120 to turn over, and the mutually close edges of the two door panels 120 simultaneously turn over downwards or upwards, so that the opening and closing of the cabin door 12 are realized.

In one embodiment, referring to fig. 5, 7 and 9, the power assembly 2 further includes a guide rod 24 disposed in the fixing frame 11 and connected to the fixing guide sleeve 23, wherein the guide rod 24 is vertically disposed, that is, the guide rod 24 is also fixedly disposed opposite to the fixing frame 11. The guide rod 24 slides through the stopper plate 22. The advantage of this is that, this guide arm 24 can carry on spacingly to limiting plate 22, guarantees that limiting plate 22 slides on vertical direction all the time, avoids limiting plate 22 to take place the displacement in the horizontal direction and influence the removal of mobile jib body 311.

In one embodiment, the underwater equipment retracting device 100 further includes a sensing assembly, which is disposed in the fixing frame 11 and is used for detecting the position of the underwater equipment 8, for example, detecting the ascending limit position and the descending limit position of the underwater equipment 8, so as to feed back to the power assembly 2, stop the power assembly 2, and the like.

Specifically, in the present embodiment, as shown in fig. 7 and 9, the sensing assembly includes at least two sensors 41, the sensors 41 are respectively disposed at the upper end and the lower end of the guide rod 24, and the limiting plate 22 slides between the upper end and the lower end of the guide rod 24, so that the sensors 41 at the upper end and the lower end can respectively sense the telescopic state of the telescopic power rod 21, and further the lifting position of the underwater device 8 can be reflected.

Referring to fig. 12, the embodiment of the present application further provides a navigation device 200, which includes a hull 9 and the underwater device retraction device 100 described in the above embodiments, wherein a moon pool 90 is disposed at the bottom of the hull 9, and a door 12 is disposed corresponding to the moon pool 90. After the hatch door 12 is opened, the underwater equipment 8 is extended out of the moon pool 90 for deployment and is recovered into the moon pool 90 and into the stationary frame 11.

The embodiment of the application provides a navigation equipment 200, the hatch door 12 of its underwater equipment collecting and releasing device 100 only needs the action of gravity can overturn downwards when opening, and need not power component 2 and additionally provide power, the hatch door 12 is driven by power component 2 that is used for driving underwater equipment 8 lift when closing, need not additionally to set up other power structures again, the form of opening and closing of hatch door 12 of this underwater equipment collecting and releasing device 100 is simpler, the holistic structure of underwater equipment collecting and releasing device 100 is also simpler, and then its cost of making and assembling can be lower, the energy consumption is also lower.
