Background
In recent years, the desire of human beings to explore the ocean and develop ocean resources is stronger, the requirement on ocean engineering equipment is higher and higher, and various novel floating ocean platforms come into play.
The ocean platform provides a structure of production and living facilities for activities such as drilling, oil extraction, collection and transportation, observation, navigation, construction and the like at sea. Because the self weight and construction cost of the fixed platform are increased sharply along with the increase of water depth, various floating platforms become the main force of offshore operation equipment and are widely used for offshore oil and gas exploitation, particularly oil and gas exploitation in deep water sea areas. The floating ocean platform is characterized in that the weight of the platform is mainly supported by the buoyancy of water, and the platform can be displaced and reused for many times. At present, the common floating ocean platforms in the world mainly comprise a semi-submersible platform, a tension leg platform, a single column type platform and a floating production oil storage and discharge device. The semi-submersible platform mainly comprises an upper structure, a buoyancy tank, a stand column and a cross brace, and is widely used as main equipment for deep sea operation because the semi-submersible platform has a large operating water depth and can better adapt to severe sea conditions. Different types of semi-submersible platforms have different requirements on performance, for example, in order to shorten the construction period and improve the working efficiency, the semi-submersible drilling platform needs to be capable of rapidly moving to a designated operation sea area on the sea, and meanwhile, the reliability of the platform in stormy waves and the safety and high efficiency of workers on the platform are ensured, so that the requirements on stability and dynamic positioning are higher when fixed-point operation is carried out; the semi-submersible production platform has the advantages that the requirements on dynamic positioning during operation are not as strict as that of a drilling platform, the operation sea area does not need to be frequently replaced, and the requirements on the stability of the platform are high.
The construction of the first deep and open sea all-weather resident floating research facility in the world leads the upgrading of high-end equipment in oceans, particularly major ocean science and technology infrastructures, drives the breakthrough and promotion of the research level in the ocean field, accelerates the promotion of understanding the ocean, developing the ocean, protecting the ocean ability construction, accelerates the fundamental change of the breadth and the depth from the shallow sea to the deep and open sea, realizes the ocean strong national strategy in the early days, and has great significance.
Slamming is a transient, highly nonlinear dynamic phenomenon created by the interaction of waves with structures, and the occurrence of transient structures is subject to dynamic loads of very high magnitude. The wave slamming principle is quite complex and is not well studied at present, especially for the problem of wave slamming in large marine structures. When the wave slamming load is too large, a significant safety hazard may occur. Therefore, a novel measuring device capable of measuring the slamming load borne by the key structural region of the ocean platform is designed, and the device is very important for accurate prediction and further research of the slamming load of the ocean platform.
There is currently no reliable numerical forecasting algorithm to determine wave slamming loads on ocean platforms. Model experiments are still a common method used to determine wave slamming loads. However, in the traditional experimental method, the slamming load is monitored by installing a pressure sensor on a drilling hole of the ocean platform structure. However, this method causes irreversible damage to the structure, the strength of the structure is reduced, and the water tightness of the structure cannot be ensured. In addition, in the prior art, the probe type pressure sensors are adopted, the pressure of a single point of the structure can be measured only, a plurality of pressure sensors are required to be arranged for monitoring the pressure distribution in a certain area, and each pressure sensor is difficult and inconvenient to arrange. In addition, pressure sensors are relatively precise, expensive, and, once damaged, lose a significant amount.

Detailed Description
The invention is further described with reference to the following figures and specific examples.
Referring to fig. 1-2, the marine wave slamming load survey device of the present invention is primarily comprised of an array of cell force modules 8 and a body plate 4 of the device. The unit force measuring module 8 is composed of a unit force measuring panel 1, a spring 2, an infrared distance measuring sensor 7 and a limiting protection device 3. The main body plate 4 acts as a cell force module 8 carrying the array and is mounted on the ocean platform in the area to be monitored by the attachment 5. The general concepts and schemes for the present embodiment are described below:
the platform is subject to wave slamming when operating in the actual sea and slamming load force monitoring is required for locations where the platform is subject to slamming and damage. The invention can be used for real-time monitoring of the slamming load condition of the ocean platform in the actual sea area when the ocean platform is slammed by waves.
The force measuring function of the unit force measuring module is realized mainly by a force measuring spring. The spring 2 is compressed and shortened when being pressed, and the spring is restored to be original length after the pressure disappears. The material and the rigidity of the spring in the actual measurement device are selected and determined according to the condition of the ocean platform and the condition of the working sea area, so that the rigidity k of the spring in each measurement unit is a known quantity.
The other main device of the unit force measuring module 8 in the invention is an infrared distance measuring sensor 7, and the infrared distance measuring sensor 7 utilizes the non-diffusion principle of infrared rays during transmission. The infrared distance measuring system is provided with a light emitting unit and a light receiving unit which are respectively used for emitting infrared laser and receiving reflected infrared laser. The distance measuring system is internally provided with a time recording module which can record the round trip time of the infrared laser. Half of the product of the speed of light and the round trip time of the infrared laser is the distance between the infrared distance measuring sensor 7 and the measured object. The force measuring units of the array are all provided with infrared distance measuring sensors, the distance from the force measuring panel of the unit to the device body is reduced along with the compression of the springs under the action of wave slamming force, the infrared distance measuring sensors can measure the change of the distance, namely the compression amount of the springs, and deformation amount signals are input into a data processing system.
The invention is provided with a data processing system and is matched with a computer terminal for use. The spring compression signal measured by the infrared distance measuring sensor 7 is transmitted to the data processing system through a data line, the data processing system processes the deformation signal according to Hooke's law to obtain a slamming force signal, and finally, the actual slamming condition of each measuring area is displayed in a visual mode through a computer, so that the real-time wave slamming load monitoring function is achieved.
Referring to fig. 3, still install connecting piece 5, connecting piece 5 installs actual measurement device on the platform stand, and the radian of junction is the same with the platform stand radian, but perfect adaptation.
Referring to fig. 1 and 2, the invention is also provided with a limit protection device 3, and the limit protection device 3 can prevent the overload damage phenomenon. When the slamming load is too large, the spring generates a large deformation amount, and the deformation amount is too large to easily cause the spring to be damaged. But the moving distance of the force measuring panel is limited due to the existence of the limit protection device. When the spring is greatly compressed, the force measuring panel touches the limiting protection device, so that the force measuring panel can not move any more, and the spring connected with the force measuring panel can not be continuously compressed, thereby preventing the overload damage condition caused by overlarge slamming load.
The invention is further illustrated by the following specific examples:
as shown in fig. 1, the marine wave slamming load actual measurement device comprises a slamming force cell panel 1, a spring 2, a limit protection device 3, a main body plate 4, a connecting piece 5 and a computer terminal 6.
As shown in fig. 2, the marine wave slamming load measuring device is also equipped with an infrared distance measuring sensor 7 mounted inside the single load cell.
The whole actual measurement device comprises the force measurement unit of array and device main part, when carrying out the reality, the main part board 4 of the actual measurement device who has installed the measuring unit is installed in the region that the platform needs to monitor through connecting piece 5 at first, and connecting piece one side is the plane and links to each other with main part board 4, and the opposite side is the curved surface that curvature radius is the same with the platform stand, and the mountable is fixed on the platform upright post. As the waves in the sea continue to act on the platform, the area to be measured is also subject to wave slamming. When the slamming load acts on the unit force measuring panel 1 at each measuring point position, the unit force measuring panel 1 transmits the slamming load force to the spring 2 connected below the unit force measuring panel 1, and the spring 2 is compressed after being stressed and then drives the unit force measuring panel 1 connected with the end part of the spring to move. At this time, the infrared distance measuring sensor 7 can measure the amount of distance the unit load cell 1 moves, that is, the amount Δ x of compression of the spring 2. The deformation quantity signal is transmitted to the computer terminal 6 through a data line, and then the data processing system processes the deformation quantity signal delta x according to Hooke's law to obtain a slamming force signal F. And finally, the computer terminal 6 displays the actual slamming condition of each measuring area as a visual result, thereby realizing the real-time monitoring function of the wave slamming load.
For each force measuring unit on the main body of the actual measurement device, the rigidity k of the spring is a known quantity, the compression quantity of the spring measured by the infrared distance measurement device is delta x, and the wave slamming force measured by the force measuring unit is as follows:
F＝k·Δx (1)
in addition, the limit protection device 3 can also prevent the overload damage phenomenon. When the slamming load is too large, the spring 2 of the measuring device is compressed a lot, and the spring 2 is damaged due to the compression. Because the limit protection device 3 is installed in the design of the embodiment, the moving distance of the force measuring panel 1 of the unit is limited, the force measuring panel cannot move any more when touching the limit protection device 3, and the spring 2 connected with the limit protection device cannot be compressed any more, so that the overload damage condition caused by overlarge slamming load is prevented.
The innovation points of the invention are summarized below:
