Description of drawings
Fig. 1 is the structural representation that pre-fixes spring structure of the special-purpose submarine pipeline leakage-baffling device of underwater robot of the present utility model.
Fig. 2 is the apparatus structure schematic representation that pre-fixes spring structure that comprises the special-purpose submarine pipeline leakage-baffling device of underwater robot of the present utility model.
Embodiment
The utility model provides the spring structure that pre-fixes of the special-purpose submarine pipeline leakage-baffling device of a kind of underwater robot, and is clearer, clear and definite for making the purpose of this utility model, technological scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Adopt underwater robot (ROV) operation leak stopping, the depth of water without limits, the submersible degree of depth that only depends on underwater robot, and the maximum diving depth 5000m of general underwater robot, and it is little that operation is influenced by sea situation, there is not the restriction of day and night, yet adopt ROV operation leak stopping, the ROV manipulator is difficult to one-time-reach-place, if leakage-baffling device and the extra large pipe of this moment can not finely be fitted, bump a little and will significantly rotate, almost do not have the possible accuracy location, the utility model namely is directed to the difficult fixing problem of leakage-baffling device of underwater robot manipulation and proposes.
As depicted in figs. 1 and 2, the special-purpose submarine pipeline leakage-baffling device of the utility model underwater robot comprises be used to the clamping plate 100 that snap fit onto on the submarine pipeline outer wall, be used for the plugging plate 200 of shutoff submarine pipeline leakage point and pass the rotating shaft 400 that clamping plate one axis hole connects plugging plate, the described spring structure that pre-fixes comprises be used to the many springs 310 that hold plugging plate, be used for being located at the fixed plate 320 of fixing described spring in clamping plate outside rotating shaft, described spring 310 is symmetricly set on rotating shaft 400 both sides and an end is fixed on the fixed plate 320, and the other end is fixed on the described clamping plate 100.Described plugging plate 200 is identical with the radius of curvature of described clamping plate 100, and not under the installment state, namely the spring in described preloading spring structure is under the relaxed state at leakage-baffling device, and described plugging plate 200 protrudes from the groove surface of described clamping plate 100 grooves.When the special-purpose submarine pipeline leakage-baffling device of described underwater robot is clamped on the submarine pipeline, because plugging plate 200 moves closer to diameter with the chord length of sea pipe point of contact, plugging plate is outwards mobile, it is and then outwards mobile to drive rotating shaft 400, the spring 310 of preloading spring structure is stretched, under the effect of recoil of spring power, plugging plate 200 obtains a power forward and is close to submarine pipeline, finishes the preliminary fixing of whole leakage-baffling device.
In the preferred embodiment, described spring 310 is two groups, and symmetry is installed in the both sides branch of rotating shaft 400 and be arranged in parallel with described rotating shaft 400, and described fixed plate 320 correspondences are arranged on the both sides of described rotating shaft.And the quantity of the spring 310 on described rotating shaft 400 corresponding both sides is identical and be that symmetry center is symmetrically distributed with described rotating shaft, and described rotating shaft number of springs on one side can be set to 3.In addition, the model of both sides spring also is the same, can guarantee the spring energized identical of the corresponding both sides of rotating shaft like this, guarantees that rotating shaft can obtain the maximum application of force longitudinally, avoids because the crooked situation of rotating shaft appears in two unbalance stress.
Because the spring pre-pressing structure of the special-purpose submarine pipeline leakage-baffling device of this underwater robot needs long period of soaking in briny environment, therefore described spring is the alloy material spring of seawater corrosion resistance, and described fixed plate is the alloy material fixed plate of seawater corrosion resistance.
As described in Figure 2 be the structural representation of the special-purpose submarine pipeline leakage-baffling device of underwater robot of the present utility model, leakage-baffling device is transferred to the setting of submarine pipeline by the handle 500 of the described leakage-baffling device of mechanical handgrip 700 clampings, groove with clamping plate 100 snaps fit onto on the submarine pipeline then, plugging plate 200 is received the extruding of submarine pipeline tube wall and is moved to groove walls at this moment, and then the fixed plate 320 of the preloading spring structure in the promotion rotating shaft 400 is to moving away from the clamping plate direction, the spring 310 that is arranged between clamping plate 100 and the fixed plate 320 is stretched, under the effect of recoil of spring power, plugging plate 200 has obtained the power of extruding submarine pipeline, it is preliminary fixing so just to make that whole submarine pipeline leakage-baffling device is able to, and underwater robot screws handle 600 and promotes rotating shaft 400 and realize promoting plugging plate by screw-thread fit and continue extruding applying submarine pipeline wall screwing by mechanism hand subsequently.The final shutoff that realizes the submarine pipeline leakage point.
The special-purpose submarine pipeline leakage-baffling device of underwater robot that the utility model provides pre-fix spring structure, adopt the submarine pipeline leakage-baffling device of this structure after snapping fit onto the submarine pipeline setting, provide pressure by pre-fixing spring structure to plugging plate, make this submarine pipeline leakage-baffling device tentatively to be fastened on the submarine pipeline, device not occurring slides, crooked situation, the firm connection of submarine pipeline leakage-baffling device has improved operating efficiency when guaranteeing follow-up underwater robot Robot actions.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
