[0038] Working principle: The structure of the wave-breaking bank is designed symmetrically along the longitudinal direction, so that the deadweight and buoyancy are symmetrical and uniform, and the rated power of the motor is appropriately increased;

[0039] The wave-breaking device installed on the pool wall is equipped with a mounting plate for installation transition. Each component is installed on the mounting plate through studs and locking nuts. The mounting plate is welded to the embedded plate of civil engineering, which is convenient for adjusting the pad during installation to eliminate civil engineering errors and for later disassembly and maintenance. During installation, the first piece of the end should be installed first, and then installed one by one in sequence to ensure that the gap between the plates and the center lines of all the bracket hinge fulcrums are on the same straight line. Skipping the installation sequence is not allowed.

[0040] The long side lifting and wave-breaking device is a necessary equipment for large-scale integrated water pools with wave resistance and maneuverability. The long side lifting and wave-breaking device is installed on the pool wall on one side of the long side of the pool. The long side lifting and wave-breaking device can rotate and swing around the fixed hinge 2, with a maximum swing angle of 87°. When in working state, it can be used to withstand the wave force generated by the wave maker. The wave-breaking device relies on the locking device, upper and lower stops and screw nuts to lock in the vertical direction, and uses the concave slide and fixed hinge 2 to lock in the horizontal direction. ;

[0041] Lifting and lowering time of wave-breaking device: the rising (falling) time of a single wave-breaking bank is 8 minutes. If several wave-breaking banks are electrically controlled to rise (fall) simultaneously, the total rising (falling) time of the wave-breaking device is 8 minutes, which meets the technical indicator requirement that the rising (falling) of the wave-breaking device can be completed within 1 hour; the lifting and lowering frequency of the wave-breaking device is about 150 times / year.

[0042] When the wave-breaking device is raised, the surface of the wave-breaking device within 800mm of the pool edge is smooth. In order to shorten the bracket structure 3 on the pool wall and increase the effective working width of the pool, the 800mm panel of the pool edge of the wave-breaking device is tilted upward by about 3° in the horizontal position; when the wave-breaking device is lowered, the smooth surface is exposed above the water surface for about 400mm and is perpendicular to the water surface, and the smooth surface is 400mm below the water surface;

[0043] When the wave-breaking device is lowered, the clearance between the end above the water surface and the pool edge is 1990mm;

[0044] When the wave-breaking device is in the raised state, there is a 400mm gap between the end of the wave-breaking device and the edge of the pool. When the wave-breaking device is in the raised state, the double amplitude of vibration at the intersection of the wave-breaking device and the water surface is theoretically not greater than 5mm (including the deformation deflection and shaking value of the body of the wave-breaking device under the action of waves).

[0045] When the wave-breaking device is raised, the stress state is: wave force in the vertical direction of the pool length ±12.5t / 10m wide, wave force in the vertical direction ±25.0t / 10m wide, wave force along the length of the pool ±12.5t / 10m wide

[0046] When the wave-breaking device is in the lowered state, the force in the direction perpendicular to the length of the water pool is ±0.5t / m (the force action area is within the wave height range of wave propagation, that is, ±0.34m from the water surface), and the vibration amplitude of the waterline part of the wave-breaking device is not greater than ±3mm.

[0047] The control system of the wave-breaking device is composed of PLC and touch-screen industrial computer. The PLC adopts the mainstream series PLC, and the touch-screen industrial computer adopts a 17-inch touch screen with an Ethernet interface. The PLC can monitor the operating status of the circuit system. When the system fails, the PLC will start the protection function and send out sound and light signals or touch screen warning information to remind the user.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
