[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-Figure 5 The utility model provides a technical solution: a fixing device for anchoring a submarine cable, comprising a fixing frame 1, a fixing frame 2, a fixing plate 3 and an anchor rod assembly 4, a fixing frame 2 is provided at the bottom of the fixing frame 1, two sets of fixing plates 3 are welded on the left and right sides of the fixing frame 2, and an anchor rod assembly 4 is inserted into each of the two sets of fixing plates 3, a limiting plate 401 is provided at the top of the anchor rod assembly 4, a nut 1 402 is sleeved on the top of the limiting plate 401, a screw rod 405 is connected to the inside of the anchor rod assembly 4, a rotating head 404 is provided at the top of the screw rod 405, a nut 2 403 is sleeved on the top of the screw rod 405, grooves 408 are provided on the left and right sides of the bottom of the anchor rod assembly 4, hinges 409 are provided on the left and right sides of the bottom of the screw rod 405, the outside of the hinge 409 is inserted into one side of a supporting claw 406, a latch is penetrated on the surface of the supporting claw 406, and the latch passes through the surface of the hinge 409, and a limiting column 407 is provided inside the anchor rod assembly 4.

[0022] As the first embodiment of the present invention: the interior of the groove 408 matches the exterior of the support claw 406, connecting rods are passed through both sides of the bottom of the anchor assembly 4, and the connecting rods pass through the surface of the support claw 406 and are inserted into the interior of the groove 408. This design allows the support claw 406 to open by moving the screw 405 upward, which is beneficial for the support claw 406 to grasp the interior of the seabed mud layer. A group of fixing columns are provided at the bottom of the fixing plate 3, and a group of fixing columns and a group of matching fixing holes are provided at the top of the limiting plate 401. This design is beneficial for fixing the fixing frame 22 and preventing the fixing frame 22 from shaking. An external thread is provided on the outside, and the external thread is meshed with a nut 402. This design can fix the fixing plate 3 and the anchor assembly 4 by tightening the nut 402. An internal thread is provided on the inside of the anchor assembly 4, and the internal thread is meshed with a screw 405. This design can drive the support claw 406 to open by rotating the screw 405. A limiting groove is provided on one side of the screw 405, and the limiting groove is inserted on the outside of the limiting column 407. This design is conducive to the support claw 406 to grasp the seabed mud layer. The overall structure of the anchor assembly 4, the fixing frame 1 and the fixing frame 2 is zinc, and this design has an anti-corrosion effect.

[0023] As a second embodiment of the present invention: first, take two groups of anchor rod assemblies 4 and knock the top of the rotating head 404 with a tool hammer. When the bottom of the limit plate 401 is connected to the top of the seabed mud layer, the rotating head 404 is rotated by a special tool to drive the screw 405 to rotate. At this time, the screw 405 is meshed with the internal thread provided in the anchor rod assembly 4, so that the screw 405 will move upward. The hinge 409 provided at the bottom of the screw 405 is connected to the support claw 406 through a latch, so an upward force of the screw 405 will be given to the support claw 406, and then through the connecting rod inserted at the bottom of the anchor rod assembly 4, the upward movement of the screw 405 will drive the support claw 406 to disengage from the inside of the groove 408, so that the support claws 406 on both sides of the bottom of the screw 405 can be grasped inside the mud layer. At this time, the limiting column 407 inside the anchor rod assembly 4 and the limiting groove provided on one side of the screw 405 are inserted to perform the operation. The support claw 406 is prevented from being perpendicular to the whole of the anchor assembly 4 and will not cause the support claw 406 to lose its grip on the mud layer. At this time, the nut 403 is turned by a wrench to tighten it to the top of the anchor assembly 4, thereby playing a secondary fixing role to prevent the screw 405 from slipping. At this time, the two groups of fixing plates 3 provided on the left and right sides of the fixing frame 2 are inserted into the tops of the two groups of anchor assemblies 4, and a group of fixing holes provided at the bottom of the fixing plates 3 are inserted into the outside of a group of fixing columns provided at the top of the limiting plate 401, thereby increasing the stability of the fixing plates 3 and the anchor assembly 4. At this time, the submarine cable is placed on the top of the fixing frame 2, and fixed to the top of the fixing frame 2 by inserting two groups of bolts on the top of the fixing frame 1, thereby completing the installation of the submarine cable. The design adds a support claw 406 at the bottom of the anchor assembly 4, which makes the support claw 406 conducive to grasping the inside of the seabed mud layer and preventing the anchor assembly 4 from detaching from the inside of the mud layer.
