Abstract
The utility model discloses a device for casting a submarine seismograph, which comprises a framework for setting the seismograph, a support plate is arranged at the bottom of the framework, one end of the support plate is hinged with the bottom of the framework and the other end of that is provided with a hook, a groove matched with the hook is formed on the bottom surface of the framework, and a releasable hook suspension mechanism is arranged on the side surface of the framework. Since the seismograph is set in the framework, when the seismograph is cast into the sea, the support plate reaches sea level at first, so that direct impact of sea water to the seismograph is weakened, the posture of the seismograph cast into the sea is ensured, and the seismograph damage is avoided.
Description
Technical field
The utility model relates to oceanic earthquake observation technology field, relates in particular to a kind of device that is used to throw in submarine seismograph.
Background technology
Submarine seismograph more and more is widely used in oceanic earthquake observation technology fields such as oceanic earthquake observation, marine geologic survey.The working method of submarine seismograph all is by throwing on the ship to marine usually, and submarine seismograph relies on the gravity of himself to sink to the seabed to observe then.Because submarine seismograph inside comprises the observation instrument of a lot of precisions, broadband seismometer in particular for the observation earthquake, these instruments all compare responsive to violent rocking, vibrate, particularly when submarine seismograph in launch process with moment of contact with sea water, may produce unexpected high vibration, this might directly cause damage to these instruments.Therefore, when throwing in submarine seismograph, reducing that these rock is one of key link that is directly connected to instrument work.
At present, throwing in submarine seismograph and all be to use a U type clamp that submarine seismograph is connected with winch, is a rope on U type clamp, when submarine seismograph is placed to the sea, draws back U type clamp again submarine seismograph and winch wirerope are broken away from.There is a problem in this input mode, be exactly when winch apart from sea (deck of ship apart from the sea when higher) when higher, the wirerope of winch will be put very long, like this because rocking of ship makes rocking that wirerope do not stop, when especially surge was bigger on the sea, this rocking will be very big, the attitude when uncontrollable submarine seismograph enters seawater, also can't alleviate vibration, be very easy to the infringement submarine seismograph in this case.
Summary of the invention
The utility model provides a kind of device that is used to throw in submarine seismograph, and attitude alleviates vibration when having solved the uncontrollable seismograph of classic method and entering seawater, and the problem that seismograph is damaged.
A kind of device that is used to throw in submarine seismograph, comprise and be used to place seismographic framework, the framework bottom is provided with back up pad, back up pad one end and framework bottom-hinged, the other end is provided with a hook, the framework bottom surface is provided with and links up with the groove that cooperates, and described framework side is provided with releasable hook suspension gear.
Described hook suspension gear comprises that the U type ring that is fixed on the framework side, the release bolt that cooperates with U type ring and top are enclosed within the tensioned lines that is used to suspend in midair hook on the release bolt.
Described framework xsect is square, and the side is provided with suspension ring all around, can framework be put into magnanimity with the rope that passes suspension ring.
The dual-side edge that described framework end face is relative is provided with vertical support bar, is fixed with leading screw between the supporting bar top, is used to hang seismograph, prevents that support plate from can't bear.
The utility model device is by placing seismograph in the framework, and when putting into nautical mile, back up pad at first touches the sea level, weakens seawater to seismographic direct impact, and can guarantee that seismograph puts into attitude in the sea, avoids seismograph to damage.
Description of drawings
Fig. 1 is the structural representation of the utility model device;
Fig. 2 is the structural representation of device framework shown in Figure 1;
Fig. 3 is the structural representation of device back up pad shown in Figure 1.
Embodiment
As shown in the figure, a kind of device that is used to throw in submarine seismograph comprises framework 1, and this framework 1 is surrounded by angle bar, roughly is square, and size will be suitable for the instrument placed, and the side evenly is provided with suspension ring 101 all around.Framework 1 bottom is provided with back up pad 2, and back up pad 2 one end both sides are provided with rotational pin 201, and rotational pin 201 passes the angle bar of framework 1 bottom, and fixes with nut, makes that support plate 2 and framework 1 are hinged.Back up pad 2 other ends are provided with hook 3, and the angle bar of framework 1 bottom is provided with and links up with 3 grooves that cooperate 103.
The angle bar of the relative both sides of framework 1 end face is provided with two symmetrically arranged support bars 5, is provided with the leading screw 6 of a level between support bar 5 tops, and this leading screw can be used for temporarily supporting seismograph, prevents that support plate from can not bear.For preventing that seismograph from moving, spacing hole 202 can be set on support plate 2.
The principle of work of said apparatus is as follows:
At first seismograph is placed on the back up pad 2 in the framework 1, discharge bolt 402 usefulness simultaneously and discharge rope 404 pullings, make the tensioned lines tensioning hold back up pad 2, in addition for preventing that seismograph is overweight, seismograph can be connected with the rope slip-knot with leading screw, in addition with two ropes pass framework around suspension ring and end compile at framework 1 top, hang on the hook of winch.
Claims (4)
1. device that is used to throw in submarine seismograph, it is characterized in that, comprise and be used to place seismographic framework, the framework bottom is provided with back up pad, back up pad one end and framework bottom-hinged, the other end is provided with a hook, and the framework bottom surface is provided with and links up with the groove that cooperates, and described framework side is provided with releasable hook suspension gear.
2. device according to claim 1 is characterized in that, described hook suspension gear comprises that the U type ring that is fixed on the framework side, the release bolt that cooperates with U type ring and top are enclosed within the tensioned lines that is used to suspend in midair hook on the release bolt.
