Description

Technical Field

[0001] The present application relates to a pressure sensor installation device, and in particular to a pressure sensor installation device for all-round measurement of dock berthing force. Background Art

[0002] The design life of the wharf is relatively long. During long-term use, the stress performance of the wharf also changes accordingly due to problems such as component aging. At present, the full life health monitoring of the wharf structure has been proposed and is increasingly being implemented. The full life health monitoring of the wharf is to bury a corresponding number of pressure sensors in each structural component of the wharf and analyze the measured pressure sensor data to determine the stress performance of the wharf as a whole and each component, providing a basis and guidance for the repair, maintenance and management decisions of the structure.

[0003] The impact force of ships during berthing has a great impact on the safety of the dock structure. With the rapid development of the water transport industry, the trend of large-scale ships has become more and more obvious, and the frequency of large ships entering and leaving the port has increased. The increase in the berthing impact force caused by the large-scale ships has increased the probability of dock damage. With the increase in the frequency of ships entering and leaving the port, the fatigue damage of the dock has gradually accumulated, reducing the safety of the structure and shortening the service life of the dock. When the ship is berthing, improper speed control and human operational errors will cause excessive impact force of the ship, resulting in damage to one or more components of the dock structure and reducing the safety of the structure. The impact force of berthing ships has become a prominent problem affecting the safety of the dock structure.

[0004] Therefore, monitoring of the berthing impact force of ships is a major part of health monitoring. In order to measure the berthing impact force more accurately, it is necessary to install a force pressure sensor between the rubber fender of the dock and the berthing structure to directly measure the impact force. However, adding a pressure sensor between the dock and the rubber fender will increase the torque generated by the vertical component of the berthing force, which will cause problems such as damage to the fender and connecting screws. In addition, the area of ​​the dock berthing structure is large, and the direction and position of the ship impact are variable, making it difficult to ensure the accuracy of the measurement. In addition, the health monitoring takes a long time, and the durability and maintenance of the pressure sensor are also very prominent. Therefore, there is currently a lack of mature methods for measuring berthing impact force. Summary of the invention

[0005] In view of the shortcomings or deficiencies of the above-mentioned prior art, the technical problem to be solved by the present application is to provide a pressure sensor installation device for measuring the berthing impact force of the dock, which can not only accurately measure the berthing force of the dock, but also ensure the stress performance of the dock-related components, and ensure the durability of the pressure sensor, and ensure the continuity of monitoring, which is of great significance for monitoring the berthing force of the dock.

The multiple pressure sensors 6 provided in this embodiment can monitor the force values ​​of various parts in an all-round manner. By measuring the magnitude and change of the force through each pressure sensor 6, not only the magnitude of the force can be measured, but also the direction of the force can be analyzed. Therefore, this embodiment can achieve the effect of accurately measuring the dock berthing force.

[0030] In this embodiment, if Figure 2 As shown, a plurality of first connecting bolts 3 are reserved on the positioning plate 7, and bolt holes matching and connected with the connecting bolts of the fender 2 are provided on the protective plate 5 and the fender 2. The protective plate 5 and the fender 2 are pressed together by the first connecting bolts 3, wherein the first connecting bolts 3 can prevent the fender 2 from falling off, and the first connecting bolts 3 themselves are not subjected to positive stress. When the fender 2 is under pressure, the first connecting bolts 3 are in a loose state.

[0031] At the position connected to the pressure sensor 6 , the positioning plate 7 is further provided with a second positioning groove 42 described below.

[0032] The first connecting bolt 3 can be connected along Figure 2 The circumferentially uniform arrangement shown is on the positioning plate 7, and the above-mentioned circumferentially uniform arrangement is evenly and stably stressed. Of course, in the specific implementation process, multiple first connecting bolts 3 can also be arranged in different arrangements according to actual needs. The specific setting number and arrangement method of the first connecting bolts 3 disclosed above do not limit the protection scope of this application.
