Description

Technical Field

[0001] This utility model relates to the field of offshore wind power engineering, specifically to an offshore wind power static cone penetration test device with a gripping system. Background Technology

[0002] With the continuous growth of global demand for renewable energy, offshore wind power, as an important component of clean energy, is gradually becoming a key direction for optimizing the energy structure of various countries. Marine geological exploration is the foundation of wind farm design, operation, and maintenance, and faces many challenges. Seabed static cone penetration testing (DCPT) is a commonly used geological exploration method in offshore wind power exploration. However, currently, the reaction force required to press the probe into the seabed can only be provided by the equipment's own weight. As the exploration depth increases, the method of providing the reaction force solely by its own weight is insufficient to meet the exploration requirements.

[0003] Based on this, this patent proposes an offshore wind power static cone penetration test device with a gripping system. The device is designed with a gripping system that can grip the seabed well and provide additional vertical reaction force for the equipment, thereby significantly increasing the exploration depth and reducing the equipment's counterweight, thus preparing for deep-sea exploration. Utility Model Content

[0004] The purpose of this invention is to provide a static cone penetration test device for offshore wind power with a gripping system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A static cone penetration test (SPT) device for offshore wind power with a holding system includes a static cone penetration test body. A holding system is arranged around the perimeter of the static cone penetration test body. The holding system includes a holding anchor mechanism and pulleys. The holding anchor mechanism includes a rope and a holding anchor body. The holding anchor body is connected to the static cone penetration test body via the rope and is used to anchor to the seabed. The pulleys are in contact with the rope and limit the direction of the tension force of the rope on the holding anchor body to the horizontal direction.

[0007] Furthermore, the holding anchor mechanism also includes a launching device, which is mounted on the static cone penetration test body. The holding anchor body is mounted on the launching device, and the launching device launches the holding anchor body.

[0008] Furthermore, the static cone penetration device body is surrounded by four gripping systems.

[0009] Furthermore, the static penetration testing device body is surrounded by six gripping systems.

[0010] Furthermore, the static penetration testing device body is surrounded by eight gripping systems.

[0011] Furthermore, when the static cone penetration test device is supported on the seabed, the pulley is located on one side of the bottom of the static cone penetration test device, making the rope L-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This utility model is equipped with a gripping system, which can grip the seabed during use, providing a greater reaction force for the probe to be pressed into the seabed, thereby improving the exploration depth and exploration performance of the equipment.

[0014] 2) Compared to the traditional method of relying solely on the equipment's own weight, the method of arranging gripping anchors around the equipment can better prevent the equipment from tilting during operation, thereby improving the quality of exploration.

[0015] 3) By providing gripping force through the gripping system, the counterweight of the equipment can be reduced, thereby reducing the structural and construction costs of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5A static cone penetration test (SPT) device for offshore wind power with a holding system includes a static cone penetration test body 1, with a holding system arranged around the perimeter of the static cone penetration test body 1. The holding system includes a holding anchor mechanism and a pulley 5. The holding anchor mechanism includes a rope 4 and a holding anchor body 2. The holding anchor body 2 is connected to the static cone penetration test body 1 through the rope 4 and is used to anchor to the seabed 3. The pulley 5 contacts the rope 4 and restricts the direction of the tension of the rope 4 on the holding anchor body 2 to the horizontal direction.

[0024] Furthermore, the holding anchor mechanism also includes an ejection device, which is mounted on the static cone penetration test body 1, and the holding anchor body 2 is mounted on the ejection device. The ejection device ejects the holding anchor body 2.

[0025] It should be noted that the catapult device is a well-known technology in the field of anchors, and will not be elaborated upon.

[0026] Furthermore, the static cone penetrometer body 1 is surrounded by four, six, or eight gripping systems, the specific number of which can be adjusted as needed.

[0027] Continue reading Figures 3-5 When the static cone penetration test device 1 is supported on the seabed 3, the pulley 5 is located on one side of the bottom of the static cone penetration test device 1, so that the rope 4 is L-shaped.

[0028] During construction, such as Figure 1 As shown, the static cone penetration test device body 1 is first lowered to the seabed 3, at which point the holding anchor body 2 is in a ready-to-launch state.

[0029] In use, the holding anchor body 2 is launched outward to the seabed 3 via a catapult device. The holding anchor body 2 is connected to the static cone penetration test equipment body 1 via a rope 4. Figure 2 As shown. Further release rope 4, bringing it to a slack state, as... Figure 3 As shown, the pulley 5 presses down on the rope 4, causing the rope 4 to be in a bent state, as... Figure 4 As shown, when rope 4 is tightened using a conventional retrieval device, the pulley 5 changes the direction of rope 4. Under the horizontal tension of rope 4, the holding anchor body 2 embeds itself into and grips the seabed 3, providing excellent horizontal tension. By further changing the direction of rope 4 using pulley 5, this horizontal tension is converted into a vertical tension, firmly securing the entire device to the seabed 3. This allows for geological exploration work.

[0030] After the survey work is completed, the equipment is recovered, such as Figure 5 As shown, first remove pulley 5, then further tighten rope 4. Since the pressure of pulley 5 is no longer applied, the force exerted by rope 4 on the holding anchor body 2 is not horizontal. The holding anchor body 2 can be easily pulled out of the seabed, thus completing the retrieval of the holding anchor body 2.

[0031] The innovation of this invention lies in adding a gripping system to the existing static cone penetration test equipment. This system provides an additional gripping force to firmly fix the equipment to the seabed, providing pressure for the probe to be pressed into the seabed. This changes the current situation where the equipment can only provide pressure through its own weight, thereby increasing the exploration depth of the static cone penetration test equipment and reducing the equipment's counterweight, thus reducing the structural and construction costs of the equipment.

[0032] The ingenuity of this technical solution lies in changing the direction of the rope by using a pulley, and using a gripping anchor that can only provide horizontal reaction force to provide vertical reaction force; and further utilizing this characteristic, the gripping anchor can be retrieved.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
