The torsion spring is fixed at the hinge point of the shovel plate 6 and the sliding block 5, and the tip of the shovel plate 6 always has upward rotation trend due to the torsion spring.
Each shell 4 on set up a cavity 13, there is a diaphragm 14 that can slide from top to bottom along cavity 13 in the cavity 13, diaphragm 14 enables cavity 13 to seal from top to bottom, diaphragm 14 lower extreme is fixed with bracing piece 15, bracing piece 15 runs through cavity 13 lower extreme face and fixes on base 1, cavity 13 lower extreme has seted up the feed liquor hole 16 with the outside intercommunication of shell 4, cavity 13 upper end has seted up the liquid outlet 17 with the outside intercommunication of shell 4, is provided with check valve 18 in the liquid outlet 17, check valve 18 makes liquid outlet 17 only can go out liquid unable feed liquor.
The lower end of each shell 4 is positioned at one end of the moving path of the sliding block 5, which is close to the vertical rod 2, a blind hole 19 is formed, a round head pin 20 is connected in the blind hole 19 in a sliding manner, a round hole 21 corresponding to the round head pin 20 is formed in the upper end face of the sliding block 5, the round head pin 20 is fixed in the blind hole 19 through a spring, and when the sliding block 5 is positioned at the innermost side, the spherical end of the round head pin 20 is arranged in the round hole 21 to limit the sliding of the sliding block 5.
Before the invention is used, all the shells 4 are positioned at the position with the largest distance from the base 1, all the sliding blocks 5 are positioned at the innermost side, the round head pins 20 are arranged in the round holes 21, the lower end surface of the shovel plate 6 is attached to the inclined surface of the inner side surface of the through groove 12 and cannot rotate, and the straight rod 7 cannot touch the switch 11;
when the device is used, the whole device is sunk into the sea floor along the vertical direction through the rope, at the moment when the base 1 contacts the sea floor, the base 1 stops descending, but the downward inertia force of the shell 4 and the torsion force of the torsion spring at the hinge point of the shovel plate 6 are combined to provide a pushing force for sliding outwards for the sliding blocks 5 through the decomposition action of the inclined plane at the inner side of the through groove 12, so that all the sliding blocks 5 overcome the blocking of the round head pin 20 and move outwards along with the downward movement of the shell 4, after the shovel plate 6 is separated from the inclined plane at the inner side of the through groove 12, under the torsion force of the torsion spring, the straight rod 7 touches the switch 11, the vibration motor 10 is started, and as the shell 4 slides downwards, the transverse plate 14 is supported by the supporting rod 15, the horizontal height is unchanged, liquid in the cavity 13 is discharged outwards through the liquid outlet hole 17, meanwhile, sea water cannot enter the cavity 13 from the air inlet hole 16, and the one-way valve 18 enables sea water to enter the upper part of the cavity 13 through the liquid outlet hole 17, so that when the upper part of the cavity 13 is compressed by the transverse plate 13, the transverse plate 13 cannot reset, the shell 4 can only move downwards relative to the base 1, and the shell 4 moves downwards under the vibration force of the vibration motor, and the sediment plate 6 is inserted downwards and is inclined downwards into the sea floor;
in the process of inserting the shovel plate 6 downwards, the inclined plane at the lower end of the sliding block 5 and the inclined plane at the inner side surface of the through groove 12 form an angle smaller than 45 degrees in the horizontal direction, so that the transverse displacement of the shovel plate 6 is larger than the longitudinal displacement, and along with the increase of the depth of inserting, the transverse resistance of sediment to the shovel plate 6 is gradually increased until the torsion of the torsion spring is overcome to lead the straight rod 7 to be separated from the switch 11, and the shovel plate at the side is firmly fixed;
after long-term fixed shooting, due to the fact that the horizontal water flow direction of the seabed is changeable, sediment around any side shovel plate 6 is possibly taken away by ocean current erosion, so that the shovel plate 6 is exposed on the seabed, the horizontal blocking force received by the side shovel plate 6 is reduced, the side straight rod 7 touches the switch 11 again under the torsion force of the torsion spring, and the vibrating motor 10 at the side is restarted to continuously jolt the shovel plate at the side downwards until the fixation is firm again;
the device can be easily pulled out of the seabed by only providing vertical upward force after being used.
The sliding block 5 is matched with the inner side surface of the through groove 12 through an inclined plane, so that the shell 4 drives the shovel plate 6 to be obliquely inserted into the seabed sediment in the descending process, a transverse fixing force is provided for the device, and the placing device is flushed away by the seabed transverse ocean current to influence shooting;
through the one-way valve 18, when the transverse plate 14 moves upwards, the upper part of the cavity 13 can only give out air and can not feed liquid, and the inertial force of the vibration motor 10 during vibration can only move the shell 4 downwards and can not move upwards;
before use, the round head pin 20 is arranged in the round hole 21, the lower end surface of the shovel plate 6 is attached to the inclined surface of the inner side surface of the through groove 12 and cannot rotate, the torsion force of the torsion spring at the hinge point of the shovel plate 6 cannot overcome the horizontal blocking force of the round head pin 20, the straight rod 7 cannot rotate the touch switch 11, after the base 1 stops moving downwards, the inertia force of the downward movement of the shell 4 and the torsion force of the hinge point of the shovel plate 6 can jointly provide a pushing force for the sliding block 5 to slide outwards through the decomposition action of the inclined surface of the inner side of the through groove 12, so that the sliding block 5 can overcome the resistance of the round head pin 20, once the sliding block 5 moves outwards until the shovel plate 6 is separated from the inclined surface of the through groove 12, the straight rod 7 is not limited to rotate by the inclined surface of the inner side of the through groove 12, and therefore the touch switch 11 is touched, and the vibration motor is started;
whether the straight rod 7 touches the switch 11 or not is controlled by torsion of the torsion spring, when the horizontal blocking force received by the shovel plate 6 is reduced due to the fact that surrounding sediment is carried away by ocean current erosion, the side straight rod 7 touches the switch 11 again under the action of torsion of the torsion spring, so that the vibration motor 10 at the side is restarted to continuously shake and press the shovel plate at the side downwards until the shovel plate is fixed firmly again, and the fixation of the sediment at the sea bottom can be firm again when the horizontal fixing force caused by ocean current erosion is reduced;
the device is fixed on the sediment on the seabed in a mode of obliquely downwards inserting the shovel plate 6, and can be easily pulled out of the sediment by only providing a pulling force in the vertical direction after the shooting work is completed, so that the device is convenient and quick to detach.
