[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The “plurality” mentioned herein generally means more than two; and when “plurality” is used to indicate the number of certain components, it does not indicate the relationship between the quantities of these components.

[0023] Please refer to Figure 1-Figure 2 , Figure 1 A structural schematic diagram of a specific embodiment of an offshore wind power foundation with a scour panoramic monitoring function is provided for the utility model; Figure 2 for Figure 1 Schematic diagram of the structure of an offshore wind power foundation with panoramic scour monitoring function from the second angle.

[0024] The utility model provides an offshore wind power foundation with a panoramic scour monitoring function, comprising a pile foundation 1 and a sensor device, wherein the pile foundation 1 comprises a first foundation section 11, the first foundation section 11 is located below the sea level A, and a part of the first foundation section 11 is buried below the seabed surface B;

[0025] The sensing device includes a plurality of sensing components 2, which are distributed at intervals along the circumference of the first foundation section 11. The sensing components 2 include at least one of a vibration sensor, a force sensor, a position sensor and a light sensor. The vibration sensor, the force sensor and the position sensor are attached to the peripheral wall of the pile foundation 1, and the light sensor is buried below the seabed surface B.

[0026] The offshore wind power foundation of the present invention monitors the scouring state around the pile foundation 1 by arranging a sensing device, wherein the sensing device includes a plurality of sensing components 2, and the plurality of sensing components 2 are distributed at intervals along the circumference of the pile foundation 1, and each sensing component 2 is responsible for the monitoring task of the corresponding area, and the sensing components 2 cooperate with each other to ensure that the seabed around the pile foundation 1 is within the monitoring range to avoid the occurrence of blind spots in monitoring; each sensing component 2 includes at least one of a vibration sensor, a force sensor, a position sensor and a light sensor, and the vibration sensor, the force sensor and the position sensor are used to detect the vibration, force and inclination information of the pile foundation, and the light sensor is buried below the seabed surface B, and the formation of the scouring pit is judged by receiving the change of light, so as to monitor the scouring state around the pile foundation 11. It can be seen that the present invention realizes panoramic monitoring of the seabed around the pile foundation 1 through a variety of monitoring means, and gives early warning, so as to facilitate timely measures to reduce losses and ensure the stable operation of the wind turbine and the booster station.

[0027] Furthermore, the offshore wind power foundation of the utility model also includes a panoramic imaging device, which is located between the sea level A and the seabed surface B, and is used to collect 360° images around the pile foundation 1.

[0028] As configured above, the panoramic imaging device can more intuitively reflect the real state of the seabed surface through image information, so as to monitor the scouring state around the pile foundation 11.

[0029] Among them, Figure 2 As shown, in this embodiment, the panoramic imaging device includes three image acquisition components 3, and the three image acquisition components 3 are distributed at intervals along the circumference of the first foundation segment 11. The angle between two adjacent image acquisition components 3 is 120°, and the monitoring angle range of each image acquisition component 3 is not less than 120°. In this way, the three image acquisition components 3 cooperate with each other to perform 360° image acquisition on the surroundings of the pile foundation 1.

[0030] Of course, in practice, the number of image acquisition components 3 included in the panoramic imaging device is not limited, and the number of image acquisition components 3 included in the panoramic imaging device can be at least one. For example, when the panoramic imaging device includes one image acquisition component 3, the image acquisition component 3 can rotate around the first basic segment 11 to achieve 360° image acquisition. The number of image acquisition components 3 is defined as N, N = 1, 2, 3..., the image acquisition components 3 are distributed at intervals along the circumference of the first basic segment 11, and the monitoring angle of each image acquisition component 3 is α, and the value range of α is: In this way, the various image acquisition components 3 cooperate with each other to ensure that the seabed around the pile foundation 1 is within the monitoring range, avoiding monitoring blind spots.

[0031] In this embodiment, the number of sensor components 2 is also three, and the three sensor components 2 are distributed at intervals along the circumference of the first basic segment 11. The angle between two adjacent image acquisition components 3 is 120°, that is, the three sensor components 2 are distributed at equal intervals along the circumference of the first basic segment 11.

[0032] In practice, there is no limit to the number of sensor components 2, and the number of sensor components 2 can be more than two. For example, when the number of sensor components 2 is two, the two sensor components 2 can be located at the radial ends of the first base segment 11, and the number of sensor components 2 is defined as M, M=2, 3, 4..., and the angle between two adjacent sensor components 2 is β.

[0033] In addition, in practice, the sensor components 2 are not limited to the above-mentioned equally spaced distribution. For example, it is also feasible to distribute the three sensor components 2 at unequal intervals along the circumference of the first base segment 11.

[0034] like Figure 1 As shown, in this embodiment, the number of sensor components 2 and image acquisition components 3 is equal, and the sensor components 2 are installed at the lower side of the corresponding image acquisition components 3.

[0035] In this way, the corresponding sensor component 2 and image acquisition component 3 can be pre-installed to form a whole, and then the whole can be installed on one side of the pile foundation, which is convenient for operation. Of course, in practice, it is also feasible to install the sensor component 2 and the image acquisition component 3 separately. At this time, the installation positions of the two are not limited. For example, it is also feasible to install the sensor component 2 on the upper side of the image acquisition component 3, or on one side of the circumference.

[0036] Furthermore, in this embodiment, the sensor assembly 2 also includes an analysis module, and the analysis module and each sensor are electrically connected. The analysis module can receive monitoring signals from each sensor and determine the scouring state around the pile foundation 1 based on the monitoring signals.

[0037] In practice, the sensor assembly 2 further includes an electrically connected signal receiver and a signal transmitter, the signal receiver and each sensor are electrically connected, and the signal transmitter and the analysis module are electrically connected.

[0038] In this way, the signal receiver is used to receive the monitoring results of each sensor. After receiving the transmission signal from the signal receiver, the signal transmitter transmits these transmission signals to the analysis module. The signal receiver and the signal transmitter play the role of signal transmission between the sensor and the analysis module. The analysis module can analyze and identify the scouring status of the pile foundation based on the received information, and determine whether remedial measures need to be taken in time to avoid the occurrence of hazards.

[0039] Among them, the structures and working principles of the signal receiver, signal transmitter and analysis module are all existing technologies well known to those skilled in the art and will not be described in detail here.

[0040] In addition, in this embodiment, the sensor device further includes a protective housing, and the sensor component 2 is arranged inside the protective housing. The protective housing should at least have a waterproof function to protect the sensor component 2 and ensure the normal operation of the sensor component 2.

[0041] Please continue to refer to Figure 1 In this embodiment, a portion of the peripheral wall of the first foundation section 11 buried below the seabed surface B is provided with a depth mark 11a.

[0042] As set above, in the initial state, the seabed surface B is at the zero scale line position. If the mud and sand on the seabed around the pile foundation 1 are washed away by the tide, current, ocean current and waves, the seabed surface B will gradually move downward. The depth mark 11a as above can more accurately indicate the degree of subsidence of the seabed surface B, thereby exerting a high warning effect.

[0043] In this embodiment, the depth mark 11a is in the form of a scale line. In practice, the depth mark 11a can also be a depth value, such as an initial value of 0, and the values ​​from top to bottom are -5, -10, etc.

[0044] In this embodiment, the peripheral wall of the first foundation section 11 is provided with a depth mark 11a only in the portion buried below the seabed surface B, that is, in the initial state, the seabed surface B is at the zero scale line position. In practice, it is also feasible to provide the depth mark 11a on the peripheral wall of the first foundation section 11. In this case, in the initial state, the zero scale line position is located on the upper side of the seabed surface B.

[0045] In addition, in this embodiment, the offshore wind power foundation also includes a monitoring unit, and the sensor device and the panoramic imaging device are connected to the monitoring unit via optical fibers.

[0046] In this way, the data and image information of the sensor device and the panoramic imaging device can be transmitted to the monitoring unit, and the operator can timely grasp the scouring status around the pile foundation 1 through the monitoring unit, so as to take timely remedial measures, reduce losses, and ensure the stable operation of the wind turbine and the booster station.

[0047] The structure and working principle of the monitoring unit are prior art well known to those skilled in the art and will not be described in detail here.

[0048] The above is a detailed introduction to an offshore wind power foundation with a panoramic scour monitoring function provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
