Description

PORTABLE STRUCTURAL SAFETY DIAGNOSIS EQUIPMENT FOR FIXED BEACON STRUCTURES AND THEREOF METHOD}

The present invention relates to a safety check equipment and method for portable top structure, in particular, these facilities are installed on the underwater reef, such as a mark or a bidding in the route sign facility that helps to ensure the safety of navigation for a navigational vessel The present invention relates to a portable isostructure safety diagnosis equipment and method for evaluating whether the performance is not conducted under the same extreme conditions.

In general, route marking facilities, such as a mark or a bidding, are facilities that can guarantee the operational safety of a sailing vessel by acting as a traffic light to ships sailing the coast. These facilities are not only the information about the route at the time of entry and departure, but also the difference between tides such as the west coast of Korea, and when there are a lot of reefs in the sea area, they can be installed on these reefs to prevent the sailing ship from hitting the reefs and be stranded. It is doing the function together.

At present, more than 100 route marking facilities such as markings and biddings are installed and operated in Korea, and most of these route marking facilities are formed by stacking concrete blocks with gravity type structures.

In addition, in the present invention, the corresponding part of the back structure 130 to which the base part 100 is fixedly installed is the upper surface of the base portion or the top surface of the back structure 130 provided on the bottom of the back structure 130. The interior of the battery compartment is provided in the appropriate, and the top surface structure 130 is difficult to access the surrounding tourists is more preferable the upper surface of the base portion relatively less impact of the elastic behavior of the tower.

However, when tourists are frequently approached due to the surrounding tourist attractions, or when the top surface of the foundation is narrow and the tower portion is not long compared to the diameter, that is, when the elastic behavior of the tower portion is not dominant, the upper surface of the top structure 130 or the battery compartment. Inside can be a good place.

On the other hand, the process for diagnosing the structural safety of the plurality of top structures installed in the sea management area using the portable back structure safety diagnostic equipment configured as described above are as follows.

First, in order to diagnose the structural safety of the back structure 130, as shown in FIG. 6 in step S100 to diagnose in a state in which the base portion 100 is fixed to a plurality of top structures 130 installed in the management sea area The diagnostic apparatus 110 is coupled to the base portion 100 of the contour structure 130.

Next, in step S110, the position information of the contour structure 130 to be diagnosed by the GPS receiver 111 is acquired from the GPS satellite and compared with previously stored information to determine which safety structure 130 is currently being evaluated for safety. Confirm and save.

Next, in step S120, the temperature is measured at the position of the contour structure 130 to be diagnosed by the temperature measuring unit 112, and is output to the display unit 115 and stored in the memory unit 116 at the same time. That is, since the behavior of the isotop structure 130 is affected by the atmospheric temperature, information on this is necessary.

Next, in step S130, by measuring the static inclination of the contour structure 130 by the inclination measuring unit 113 to confirm and store. In this case, the memory unit 116 stores the allowable range of the static inclination from the initial inclination and the existing diagnosis result through several diagnosis of the contour structure 130. If the range is satisfied, it is stored in the memory unit 116. If the range is not satisfied, the external conditions such as the state of the base unit 100 and the state of close contact between the diagnostic apparatus 110 and the base unit 100 are again restored. After checking, re-measure.

Here, when there is no change of the static inclination even when the static inclination measurement of the contour structure 130 by the inclination measuring unit 113 is repeated a predetermined number of times, for example, three times of remeasurement, the memory unit 116 is stored in the memory unit 116.

In this case, the static inclination by the inclination measuring unit 113 measures the static inclination in two orthogonal directions on the plane of the back structure 130, for example, the N-S and the E-W directions.

Next, in step S140, the dynamic acceleration along with the dynamic tilt of the contour structure 130 is measured for a predetermined time, for example, 10 minutes, and stored in the memory unit 116.

At this time, when measuring the dynamic slope and dynamic acceleration of the contour structure 130, the dynamic slope and the dynamic acceleration, as shown in Figure 7, reads the value for a particular axis on the plane of the longitudinal structure of the contour structure 130. , The dynamic gradient and the dynamic acceleration consist of two axes orthogonal to each other in various cross-sections on the plane with respect to the longitudinal direction of the isotop structure 130.

That is, if the isostructure 130 has a symmetrical cross section in a plane such as a circle, a square, a regular hexagon, a regular octagon, or the like in the longitudinal direction, the value in any direction may be measured, but between two axes of dynamic slope and dynamic acceleration, It is preferable to maintain orthogonality with each other because it can improve orthogonality and independence of measurement data.

In this way, the comprehensive information of the contour structure 130 stored in the memory unit 116 is read in a separate operating system to analyze the more strict behavior characteristics in detail and manage the history information therefor.

As described above, the present invention provides only the base unit 100 in the isotopic structure 130 by carrying out the above-described procedure, carrying the diagnostic apparatus 110, and checking the light register and battery, cleaning the battery compartment, and cleaning the solar panel. When performing, it is possible to easily measure the items related to the structural safety of the back structure 130, and also can be efficiently managed by easily diagnosing a plurality of the back structure 130 installed in the sea management area.

In addition, the present invention can be applied to the structure of the general gravity-type offshore structure, for example, gravity caisson quay wall, gravity caisson breakwater, etc. in addition to the back surface structure 130 can increase its utilization.

In the above, the present invention has been described as an embodiment, but the present invention is not limited to the above-described embodiments, and those skilled in the art without departing from the gist of the present invention claimed in the claims. Anyone can make a variety of variations.
