Description

A quick connect location structure and ocean flotation tank for offshore flotation tank assembles

Technical Field

The invention relates to the technical field of buoyancy tank components, in particular to a quick connection positioning structure for assembling a marine buoyancy tank and the marine buoyancy tank.

Background

At present, a plurality of modules are assembled to form an offshore buoyancy tank, and adjacent buoyancy tank modules are connected by adopting joints. The general problems of the buoyancy tank module in the offshore assembling process mainly include: because the stable location of relative position is lacked between two adjacent flotation tank modules to cause the articulate operation degree of difficulty very big, both consumed plenty of time and consumed a large amount of manpower and materials.

In order to solve the above problems, the quick connection positioning structure for offshore buoyancy tank assembly, which is proposed by the publication No. CN104192278B, includes a connection positioning seat and a connection positioning component which are arranged on a buoyancy tank module; and at least two connecting and positioning seats are arranged corresponding to each connecting surface of the buoyancy tank module, and the two buoyancy tank modules are connected and close to each other through the connecting and positioning parts.

After the connection positioning is completed, the connection operation of the joint can be conveniently implemented, and the buoyancy tank modules are connected into a whole by adopting the joint.

However, the quick connection positioning structure has the following defects: after the buoyancy tank module is assembled with the joints, the positioning parts need to be connected reversely: firstly, the positioning pin shaft and the soft cable are drawn out from the pin shaft hole. However, the soft cable is generally long, so that it is time consuming to completely withdraw the connecting and positioning component, and because of the flexibility of the soft cable, the end far away from the positioning pin is twisted or knotted during the withdrawal (before) process, which will affect the withdrawal of the connecting and positioning component. Secondly, as the buoyancy tank modules are generally operated on the sea or in the lake, the buoyancy tank modules are greatly influenced by wind and waves, and if the soft cable slides in the operation process, the approach of the two buoyancy tank modules is influenced, so that the positioning connection operation is realized. Thirdly, the installation and connection positioning seat can be conveniently connected with a positioning part for use, although the connection of the buoyancy tank module is convenient, due to the fact that the installation and connection positioning seat is preassembled, the overall layout of the buoyancy tank module is influenced if the installation and connection positioning seat is not disassembled, manufacturing materials are added, and the installation and connection positioning seat at least protrudes out of the buoyancy tank module, so that the attractiveness is influenced.

In the present invention, in order to facilitate the formation of the holes, the connecting and positioning groove 2 has a tubular structure, which may be a circular tube or a square tube. The position of the connection positioning groove 2 in the vertical direction is located near the deck surface of the buoyancy tank module so as to facilitate the connection operation. As shown in the top view state of fig. 1 and the side view state of fig. 2, the notch 3 is reserved in the connection positioning slot 2, so that the rod body 5 and the connection positioning slot 2 can be very conveniently assembled and disassembled, or the free end of the flexible cable 6 penetrates through the notch 3 and penetrates into the connection positioning slot 2 of the opposite buoyancy tank module 1.

The step 4 is arranged at the same time, so that the strength of the connecting positioning groove 2 can be enhanced on the basis that the two buoyancy tank modules 1 can be gradually close to each other and positioned relatively by pulling the soft rope 6.

In the invention, as shown in fig. 3, after two buoyancy tank modules 1 are gradually close to each other and are relatively positioned, the end of the rod 5 far away from the anti-dropping block 11 can be inserted into the connecting positioning groove 2 of the opposite buoyancy tank module 1, that is, the sizes of the rod 5 and the connecting positioning groove 2 can be flexibly set according to actual conditions. The connecting and positioning grooves 2 are of an integrated structure on the buoyancy tank module 1 and are prefabricated when the buoyancy tank module 1 is manufactured. The connecting and positioning part 21 is movable and can be used repeatedly. And connect constant head tank 2 through setting up, can avoid additionally making the connection positioning seat among the prior art, and also avoided will connecting the positioning seat with trompil spiro union or weld/the mode of gluing fix to flotation tank module 1 on, can reduce the holistic weight of flotation tank module 1, make the installation degree of difficulty reduce, be convenient for pull, it can play hidden purpose to connect locating part 21 simultaneously when using, it exposes to flotation tank module 1 and takes place winding risk outward to have reduced the soft cable 6, it additionally increases the requirement like connecting the positioning seat among the prior art to have reduced to connect locating part 21 to needs. The whole buoyancy tank module 1 is also more aesthetically pleasing when in use.

According to the invention, one end of a flexible cable 6 is connected with a connector 9, a rod body 5 is provided with a channel 7, the end part of the flexible cable 6 and the connector 9 pass through the channel 7 to reach one side of an anti-drop block 11, then a pin 10 is inserted on the connector 9, then the free end of the flexible cable 6 passes through a connecting positioning groove 2 of another buoyancy tank module 1, and then force is applied to the free end, so that the two buoyancy tank modules 1 gradually approach each other and are relatively positioned. In order to facilitate the passage through the passage 7, the diameter of the connecting head 9 may be adapted to the inner diameter of the passage 7. As shown in fig. 4, after the buoyancy tank module completes the joint assembly, the pins 10 are removed from the joints 9, so that the joints 9 can slide out of the corresponding channels 7 and then exit from the connection positioning grooves 2.

According to the invention, the auxiliary positioning component 12 comprises an installation block 13 and clamping blocks 15, a threaded rod 23 is installed at the bottom of the installation block 13, a screw hole matched with the threaded rod 23 is reserved in the connection positioning groove 2, a hole 14 is formed in the middle of the installation block 13, the clamping blocks 15 are symmetrically installed on two sides of the hole 14 and are in sliding connection with the installation block 13, a plurality of positioning heads 8 distributed at intervals are arranged on the soft rope 6, and the positioning heads 8 can be matched with the holes 14 and are limited to retreat by the two clamping blocks 15. The mounting block 13 is provided with a groove 16 for enabling the fixture block 15 to slide, the end of the fixture block 15 is provided with an anti-falling plate 18, the anti-falling plate 18 is provided with an elastic member 17, and the end of the elastic member 17 is fixed on the groove 16. The side surface of the fixture block 15 is provided with a rolling element 19, and the rolling element 19 is in rolling connection with the side wall of the groove body 16. One side of the fixture block 15 is a round angle surface 20, and the other side is a right angle surface 22.

According to the invention, the auxiliary positioning component 12 is arranged to ensure that the soft rope 6 is pulled in one direction. Due to the hole 14, the positioning head 8 can be matched and passed through, and telescopic clamping blocks 15 are arranged on two sides of the hole 14. As shown in fig. 5, when the positioning head 8 is located on the auxiliary positioning component 12, it is initially described as being located on the left side of the auxiliary positioning component 12: at this moment, two fixture blocks 15 are in the state of stretching out into hole 14, and the fillet face 20 of fixture block 15 tip is close to the one side at location head 8, when location head 8 entered into hole 14 in, thereby can push back two fixture blocks 15 through fillet face 20, make its tip retract in cell body 16, thereby can make location head 8 reach the right side of auxiliary positioning component 12 through hole 14, at this moment under elastic component 17, preferably the effect of spring, make two fixture blocks 15 be in the initial condition before the arrival that stretches out again, and the right angle face 22 of fixture block 15 tip blocks the effect, can avoid location head 8 back to retreat in the hole 14.

In the invention, the anti-falling plate 18 and the fixture block 15 are approximately in a T shape, so the groove body 16 can be a T-shaped groove, and the anti-falling plate 18 can prevent the fixture block 15 from falling into the hole 14 when extending out. Moreover, due to the rolling elements 19, such as balls or rollers, the blocks 15 can be extended or retracted more easily, and the stability during extension and retraction can be ensured. So that the fixture block 15 has a good guiding function in sliding in the vertical direction. The rounded surface 20 reduces the resistance of the alignment head 8 to passing through the hole 14, thereby maximizing the throughput of the alignment head 8 and avoiding damage to the alignment head 8 by the end portions. The diameter of the positioning head 8 may be the same as the diameter of the connecting head 9. The channel 7 is arranged on the rod body 5, so that the disconnection of the soft cable has high reliability on the basis of reducing the self weight.

According to the invention, a plurality of positioning heads 8 are prefabricated on the soft rope 6 and are uniformly distributed at intervals, so that two buoyancy tank modules 1 can approach each other when the soft rope 6 is manually pulled. By the cooperation of the positioning head 8 with the auxiliary positioning element 12, for example, the following can be avoided: when the approaching buoyancy tank module 1 is affected by wind and waves, a large force is applied to the flexible cables 6, which may cause the approaching buoyancy tank module 1 to move away again or may cause the approaching buoyancy tank module 1 to move away again due to other situations in which the flexible cables 6 need to be loosened. And the positioning head 8 can also be used as a friction bump on the soft cable 6, so that the friction force when the soft cable 6 is dragged manually is enhanced, and the slipping phenomenon between the hand and the soft cable 6 can be effectively avoided. Furthermore, the positioning head 8 is arranged, so that the risk of knotting of the free end can be reduced on the basis of ensuring that the flexible cord 6 is flexible and can pass through the channel 7, the connecting positioning groove 2 and the notch and the hole 14 thereof. When the two buoyancy tank modules are dragged by the soft rope 6, the two buoyancy tank modules approach each other until the rod body 5 is inserted into the connecting positioning groove 2 of the opposite buoyancy tank module 1, and the connecting positioning is completed. After the connection and the positioning are finished, the connection of the buoyancy tank module joint can be conveniently carried out. After the joint assembly is completed, the rod body 5 and the soft rope 6 are disconnected, and the rod body 5 and the soft rope 6 respectively exit from the corresponding connecting positioning grooves 2. After the soft rope 6 is withdrawn, the rod body 5 and the mounting block 13 can be taken out or detached from the corresponding connecting positioning groove 2 respectively. It should be noted that the mounting block 13 is mounted and dismounted by a threaded rod 23 mounted at the bottom and a screw hole reserved in the connecting positioning groove 2.

In the invention, the rod body 5 and the soft rope 6 are disconnected, and the rod body 5 and the soft rope 6 are respectively withdrawn from the corresponding connecting positioning grooves 2 in opposite directions and independently withdrawn from each other, so that on one hand, the connecting positioning part 21 can be rapidly withdrawn and separated from the connection with the buoyancy tank module 1, and the connection limitation of the connecting positioning part 21 on the buoyancy tank module 1 is avoided, and on the other hand, the rod body 5 and the soft rope 6 can be rapidly discharged from the connecting positioning grooves 2 because the rod body 5 and the soft rope 6 are separated and independently and reversely detached, and the phenomenon that the free end (which can be rolled in advance) is knotted in the process that the soft rope 6 is withdrawn from the connecting positioning grooves 2 can be avoided.

The invention also provides a marine buoyancy tank which comprises the quick connection positioning structure. The detailed structure of the quick connection positioning structure can refer to the above embodiments, and is not described herein again; it can be understood that, because the above-mentioned quick connection positioning structure is used in the marine buoyancy tank of the present invention, the embodiment of the marine buoyancy tank of the present invention includes all technical solutions of all embodiments of the above-mentioned quick connection positioning structure, and the achieved technical effects are also completely the same, and are not described herein again.

After the connection and the positioning are completed, the connection of the joint of the buoyancy tank module can be conveniently carried out. After the connectors are assembled, the rod body 5 and the soft cable 6 are disconnected, the pin 10 is pulled out of the connector 9, so that the connector 9 can slide out of the corresponding channel 7 and then quit from the connecting positioning groove 2, and the rod body 5 and the soft cable 6 only need to quit from the connecting positioning groove 2 corresponding to the connector.

According to the invention, the free end of the soft rope 6 can firstly pass through the channel 7 of the rod body 5, the pin 10 is inserted into the connector 9, then the free end passes through the connecting positioning groove 2 of one buoyancy tank module 1 to the outside of the connecting positioning groove 2 of the opposite buoyancy tank module 1, and then the soft rope is manually pulled, so that the two buoyancy tank modules 1 are close to each other until the joint assembly is completed and the connecting positioning part 21 is withdrawn.

The invention can provide a quick buoyancy tank stable positioning function for the assembly operation of the offshore buoyancy tank module. By utilizing the assembling method, the two buoyancy tank modules 1 to be assembled can be quickly moved to the assembling connection position by adopting manual operation, and the relative positions of the two buoyancy tank modules 1 can be kept stable. After the connection and positioning are completed, the connection operation of the buoyancy tank joints can be conveniently implemented, and the buoyancy tank joints are adopted to connect the buoyancy tank modules 1 into a whole.

The invention can bear the impact force generated by the relative movement of the buoyancy tanks on two sides under the sea condition of buoyancy tank assembly operation, so that the relative positions of the two buoyancy tank modules 1 are kept still, and the operation of joint connection is greatly facilitated. After the joint connection is completed, the rod body 5 and the soft cable 6 which are connected with the positioning part face to the respective opposite directions and are independently withdrawn, and the device can be repeatedly used.
