Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment design related to hydrodynamics and fluid mechanics, and relates to an adjustable portable wave height meter bracket suitable for a large pool. Background Art

[0002] In the field of shipbuilding and marine engineering, water tank simulation experiments are an important method to explore the impact of natural phenomena such as wind, waves, and tides on offshore structures. These experiments are usually conducted in water tank laboratories equipped with wave machines, circulating water tanks, wind-generating devices and other facilities to simulate real sea conditions. As a key device for measuring wave height, wave height meters are widely used in ship model experiments to monitor relevant ocean parameters and calibrate and analyze waves. In water tank tests, wave height meters are mainly used to measure the waves generated in the water tank. The wave height meter bracket is used to support and stabilize the wave height meter to ensure that it can accurately measure the height and characteristics of waves at different locations when simulating the marine environment or conducting hydrodynamic studies.

[0003] However, the existing installation methods of wave height meters have significant limitations. For example, the existing wave height meters often have cumbersome and time-consuming operations during installation and disassembly, which not only affects the test efficiency but also increases the operating cost. For different water depth conditions, the height adjustment of traditional wave height meters often requires re-adjustment of the entire equipment, which is not only time-consuming and labor-intensive, but may also affect the measurement accuracy and stability. When a wave sequence acts, the fixing method of the traditional wave height meter is prone to loosening, resulting in inaccurate measurement data or even equipment damage. The existing technology lacks special clamps that are compatible with the wave height meter, which makes the installation and adjustment process of the wave height meter more complicated, thereby increasing the time and money costs of the experiment.

[0004] In response to these problems, a series of patent technologies have been proposed, aiming to develop a wave height meter installation device that can automatically adjust the height and position. For example, CN204825774U discloses a universal lifting wave height meter bracket, which adopts a lifting rod provided with a plurality of second through holes with the same vertical spacing, fixed by screws and nuts, and the height of the bracket can be adjusted. At the same time, there are legs with different support methods for use on the ground and in the sink, but the operation of the screws and nuts is not convenient, and the legs used for support on the ground are L-shaped legs, and the bracket is not stable enough.

[0005] Another patent (CN114879749A) discloses an automatically adjustable wave height meter bracket control system and control method, which monitors the water depth through an ultrasonic level sensor and automatically adjusts the height of the wave height meter so that it is always in a suitable measurement position. This technology uses the method of automatically adjusting the height of the wave height meter to effectively reduce manpower and time costs, but does not involve the design of the bracket.
