Description

Technical Field

[0002] Gravity anchors are the most traditional underwater anchoring method, securing equipment to the seafloor through their own weight. Typically made of metal and often conical or flat in shape, they rely on their own weight to insert into the seafloor sediments and provide a secure hold.

[0003] However, traditional gravity anchors still have certain defects. For example, they are easily impacted by water flow, resulting in unstable equipment fixation or position displacement. Secondly, common fixing methods are complicated to operate, and in underwater environments, due to factors such as water flow and sediment deposition, the fixing device is difficult to recover and adjust after long-term use, which increases the difficulty of maintenance and operation.

[0009] According to the underwater fixing device based on the working principle of the anchor, the limiting arc hole is 120 degrees, which is used to provide a 60-degree movable angle for the anchor as a whole.

[0011] According to the underwater fixing device based on the working principle of the ship anchor, the number of the anchor rods is two.

[0012] According to the underwater fixing device based on the working principle of the ship anchor, the anchor rod is slightly curved, and the front end of the anchor rod is pointed, so that the anchor can be inserted into the riverbed easily.

[0013] According to the underwater fixing device based on the working principle of the ship anchor, the outer surface of the mud and sand baffle is in an arc shape, which reduces the impact force of the water flow.

[0025] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0026] Reference Figure 1-4 The outer surface of the anchor body 1 is in contact with the limiting arc plate 3, and the number of limiting arc plates 3 is two, and the number of anchor rods 8 is two, and the anchor rods 8 are slightly curved, and the front end of the anchor rods 8 is pointed, and the outer surface of the mud and sand baffle 4 is cambered.

[0027] Working principle: When in use, the device is sunk to the bottom of the water, and is gradually pressed into the riverbed or the mud and stones on the bottom of the water by its own weight. During the sinking process, the chain buckle 6 first contacts the surface of the riverbed. With its slightly curved and pointed design, the water flow gives a force to the anchor tip, so that the anchor rod 8 can gradually penetrate the riverbed, forming a stable grip effect. At this time, the limiting arc plate 3 is inside the limiting arc hole 9, and at the same time limits the overall rotation angle of the anchor rod 8, thereby ensuring that the tip of the anchor rod 8 always remains at the best grip angle, thereby preventing excessive movement or rotation caused by water flow impact or external force, thereby ensuring the device The stability and firmness of the fixation are such that when the anchor rod 8 is fully inserted into the mud and stones on the riverbed or the bottom of the water, it can remain fixed for a long time under strong water flow. When the entire device needs to be recovered, the operator only needs to pull the chain at the tail of the anchor to connect it to the device through the chain buckle 6 for recovery. The chain makes the pulling direction parallel to the gripping direction of the anchor rod 8 through the limiting arc plate 3, thereby reducing the friction resistance between the anchor rod 8 and the riverbed. Then the anchor rod 8 will easily break away from the riverbed during the pulling process. The whole process realizes the efficient combination of stable fixation and low-resistance recovery, ensuring the convenience and safety of operation of the device in complex underwater environments.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
