Abstract
The invention relates to a fixture device of a deepwater floating platform rib anchor chain sensor. The device is characterized by comprising a T-shaped fixture body, self-locking devices and a sensor bearing cylinder; three ends of the T-shaped fixture body are respectively provided with one self-locking device; and the sensor bearing cylinder is horizontally fixed on the wing plate of the T-shaped fixture body. The device disclosed by the invention is not only used for effectively preventing the installed sensor from sliding along a chain ring but also used for preventing the sensor from rotating relative to the chain ring and ensuring the good in-place working state of the sensor. Simultaneously, a diver serves as an installation carrier; the diver can sufficiently play subjective initiative; more complex works can be completed; and installation risks resulted from reasons, such as improper operation, ocean current disturbance and the like, can be reduced.
Description
Technical field
The present invention relates to a kind of grip device, the grip device of rib anchor chain sensor is particularly arranged about a kind of deepwater floating platform.
Background technology
The field monitoring of deepwater floating platform is significant for the design that ensures platform safety operation, evaluation platform and verification model test.For platform property being carried out monitoring reliably and with long-term, need to guarantee monitoring sensor installation in place reliably and with long-term.The deepwater floating platform monitoring comprises Floating System, mooring system and riser systems.Wherein install at the scene of mooring system and riser systems sensor needs underwater operation.The existence must face water environment is installed under water, the scene of sensor install can only rely on the frogman or under water ROV finish.Because the impact of diving physiology and diving outfit, the safety work degree of depth of conventional diving be about 60 meters, and adopt have an appointment 650 meters working depth of the saturation diving of underwater vehicle.Along with the development of deep diving technology, it is under water dark that the frogman can slip into hundreds of rice by various diving apparatuses, finishes the work such as installation, salvaging.Finish to install under water with simple dependence ROV and compare, the frogman can give full play to its subjective initiative, can finish more complicated work, reduces the installation risk that produces owing to reasons such as misoperation, ocean current disturbances.
Anchor clamps are to be used for fixing processing object in the machine-building process, make it to occupy correct position, with the device of accepting construction or detecting.In broad terms, any operation in technological process is used for rapidly, the device of convenient, safe installation workpiece, can be called anchor clamps, such as weld jig, assembling jig, jig etc.Anchor clamps are comprised of setting element, clamp device, Connection Element and clamp body etc. usually.Because anchor clamps have rapidly, make things convenient for, reliable characteristics, obtained widely application in the oceanographic engineering field, such as anode block anchor clamps, submarine pipeline reparation anchor clamps with pressure of the anticorrosion middle use of submarine pipeline etc.Anchor clamps have also been brought into play important effect in installation of sensors in deep water monitoring field, and a lot of engineering application cases have abroad also been arranged, and have proved that anchor clamps can satisfy precision and the fiduciary level requirement of installation of sensors.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide the grip device that a kind of deepwater floating platform has the rib anchor chain sensor, thereby this device as being installed, carrier reaches monitoring sensor installation purpose take the frogman.
For achieving the above object, the present invention takes following technical scheme: a kind of deepwater floating platform has the grip device of rib anchor chain sensor, it is characterized in that: it is comprised of T-shaped clamp body, self-locking device and sensor carrying cylinder; Three ends at described T-shaped clamp body all arrange a described self-locking device; Described sensor carrying cylinder is horizontally fixed on the wing plate of described T-shaped clamp body.
Described self-locking device comprises the locking member of three lobe annulars and the elastic component of two arcs, described locking member is connected through the hinge by a semi arch and two 1/4 circular arcs and forms, and two described elastic component symmetries are installed in the outside of described locking member.
Described sensor carrying cylinder is a tubular construction, is provided with the installation of sensors guide rail on the described sensor carrying cylinder and sensor shirks button.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention is according to the design feature that the T-shaped connection in middle part of rib anchor chain is arranged, adopt T-shaped clamp body arrangement form, not only respectively form unidirectional hinged-support at vertical anchor chain chain link with along the chain link direction, and formed a unidirectional hinged-support at the anchor chain flank.By being arranged in the hinged constraint of three ends of T-shaped clamp body, not only can effectively prevent from rear sensor being installed along the slip of chain link simultaneously, also can prevent from having guaranteed the good working state that sensor is in place relative to the rotating of chain link.2, the present invention makes the frogman can give full play to its subjective initiative take the frogman as carrier is installed, and can finish more complicated work, reduces the installation risk that produces owing to reasons such as misoperation, ocean current disturbances.

Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention is comprised of T-shaped clamp body 1, self-locking device 2 and sensor carrying cylinder 3.Wherein T-shaped clamp body 1 rigid connector that is whole grip device makes whole grip device become a rigid unitary.Design feature according to the T-shaped connection in middle part of rib anchor chain is arranged all arranges a self-locking device 2 in three ends of T-shaped clamp body 1.Sensor carrying cylinder 3 is sealable tank devices of placing the self-tolerant sensor, and it is horizontally fixed on the wing plate of T-shaped clamp body 1.
In above-described embodiment, self-locking device 2 comprises the locking member 21 of three lobe annulars and the elastic component 22 of two arcs, locking member 21 is connected through the hinge by a semi arch and two 1/4 circular arcs and forms, and two elastic component 22 symmetries are installed in the outside of locking member 21.
In above-described embodiment, sensor carrying cylinder 3 is a tubular construction, be provided with installation of sensors guide rail 31 and sensor on the sensor carrying cylinder 3 and shirk button 32, the location when installation of sensors guide rail 31 can guarantee replacing sensor, thereby the accuracy of assurance measurement result; Sensor shirks button 32 plays snap close when working sensor effect, avoids sensor to come off from sensor carrying cylinder 3, and is convenient to change when emat sensor more.
During the on-the-spot installation of the present invention, at first on the water the elastic component 22 of forced locking device 2 is opened, hung to be carried into by the frogman afterwards under water and subscribe the installation site; Then with grip device according to T-shaped placement and with have rib anchor chain middle part parallel, according to the three-point fix principle locking member 21 is inserted with the rib anchor chain inner, finish the location work before fastening; Press respectively at last the elastic component 22 in three locking member 21 outsides, get final product auto lock and grip device has been installed in (as shown in Figure 3) on the rib anchor chain.
The present invention only describes with above-described embodiment; the structure of each parts, setting position and connection thereof all can change to some extent; on the basis of technical solution of the present invention; all improvement and equivalents of individual component being carried out according to the principle of the invention all should not got rid of outside protection scope of the present invention.
