The box beams 11 on both sides are not sealed as water tanks 111, with elliptical notches at the bottom and air holes at the top. The five groups of box beams 11 in the middle are sealed and serve as floating tanks 112 to reduce the weight of the lifting and wave-breaking body 1; the bottom of the rear side of the box beams 11 on both sides is provided with a protruding flat square box structure, and the bottom of the rear side of the five groups of box beams 11 located in the middle of the box beams 11 on both sides is provided with a slightly shorter protruding flat square box structure; the wave-blocking door is provided at the rear end of the wave-breaking device and is installed on the flat square box structure, the wave-blocking door and the pool side are provided with a drain trough, the bottom of the wave-blocking door is provided with an inclined wedge block 3 that can be inserted into the rear end of the wave-breaking device, and the middle end of the wave-blocking door is connected to the wave-breaking bank body by bolts.

[0023] The wave-breaking strip 12 is mounted on the box beam 11. The wave-breaking strip 12 is a stainless steel square tube with a wall thickness of 2 mm, a cross section of 60×60 mm, a spacing of 40 mm, and a distance of 20 mm from the curved surface. A number of pads 121 are pre-welded on the wave-breaking strip 12. A through hole is opened in the middle of the pad 121, and then the pad 121 is bolted to the box beam 11 with a countersunk screw nut 122. Then, the bolt hole is sealed with epoxy resin and polished to be smooth. There is no protrusion on the upper surface of the wave-breaking strip 12.

[0024] In this embodiment, the traction system 4 includes a winch and a movable pulley, wherein the movable pulley is arranged at the end of the lifting and wave-breaking body 1. The winch can pull the movable pulley at the end of the lifting and wave-breaking body 1, and enable the lifting and wave-breaking body 1 to swing up and down around the fixed hinge shaft 2 and perform lifting and lowering movements.

[0025] In this embodiment, the locking mechanism includes a horizontal locking assembly and a vertical locking assembly, wherein the horizontal locking assembly utilizes an inclined wedge block 3 and a front-end fixed hinge shaft 2 for horizontal locking, and the vertical locking assembly includes a rigging turn buckle 5 arranged on both sides of the lifting and wave-breaking body 1, and the vertical locking assembly is locked in the vertical direction through the rigging turn buckle 5 and the front-end fixed hinge shaft 2.

[0026] In this embodiment, the bottom support 6 is located at the lower side of the lifting wave-breaking body 1 , and a water-stopping rubber is provided on the bottom support 6 .

[0027] In this embodiment, semi-circular steel supports are installed on both sides of the rear end of the lifting wave-breaking body 1. The semi-circular steel supports are used to be placed on the bottom support 6 of the pool bottom when the lifting wave-breaking body 1 swings around the fixed hinge shaft 2 to the lowest limit position.

[0028] In this embodiment, when the device is in the raised state, the vertical wave force is borne by the rigging turn buckles 5 arranged on both sides of the wave-breaking bank body and the fixed hinge point at the front end of the wave-breaking bank, and the horizontal wave force parallel to the pool wall and perpendicular to the pool wall is borne by the inclined wedge device arranged on both sides of the wave-breaking bank body and the fixed hinge point at the front end of the wave-breaking bank.

[0029] In this embodiment, the wave-breaking bank has two working states: raised and lowered, so the wave-breaking bank needs to swing up and down at a fixed angle around the front hinge. Since most of the wave-breaking bank is submerged in the water and part is exposed above the water, after comparing multiple plans, the wave-breaking bank is lifted and lowered by a winch. The winch wire rope is wound around the movable pulley and horizontal guide wheel at the end of the wave-breaking bank body structure, driving the wave-breaking device to swing up and down around the front fixed hinge.

[0030] In this embodiment, the electric control system is used to control the opening and closing of the entire lifting and wave-breaking device.

[0031] In the specific implementation, the hoist drum is equipped with a lifting height limiter to position the lifting height of the wave-breaking bank; the pulley shaft is equipped with a load sensor. A load sensor is installed on the pulley shaft of a fixed pulley on the bank side of the pool to detect the stress of the steel wire rope of the wave-breaking device.

[0032] When implementing the wave-breaking device, the civil engineering interface construction needs to be completed first:

[0033] The civil engineering interface includes: embedded plates on the central columns of the pool, embedded plates on the bottom of the pool, and the winch foundation pit setting on the short side of the pool.

[0034] Embedded plates 7 on both sides of the dock pool wall are mainly used for the installation of the inclined wedge locking device and the rigging turn buckle 5 on both sides of the dock wave-breaking device.

[0035] Embedded plate on the center column of the pool: used for installing the fixed hinge point at the front end of the wave-breaking device.

[0036] Pool bottom embedded plate: used to install bottom support 6.

[0037] An embedded plate is set at the winch foundation pit on the short side of the pool: used to install the guide pulley and winch base. The edge of the winch foundation pit is protected by equilateral angle steel 50×5 and -20×50 plates. The top surface of the foundation pit cover is guaranteed to be flush with the floor of the pool bank.

[0038] The specific implementation parameters are as follows:

[0039] When the wave-breaking device is lowered, it is ensured that the wave-breaking device can be lowered to about 1.8m below the water surface to ensure that the ship model can enter and exit the pool normally;

[0040] When the wave-breaking device is raised, there is a 200mm gap between the wave-breaking device wave-blocking door and the pool edge;

[0041] When the wave-breaking device is in the raised state, the stress state is: wave force in the vertical direction of the pool length ±12.5t / 10m width, wave force in the vertical direction ±30.0t / 10m width, wave force along the length of the pool ±12.5t / 10m width (Note: When calculating the structure, according to the requirements of DL 5077-1997 "Load Design Code for Hydraulic Structures", the wave force is increased by 1.2 times the safety factor);

[0042] The dimensions of the wave-breaking strip 12 are as follows: the cross section is 60×60mm, the spacing is 40mm, and the distance from the curved surface is 20mm. The material is stainless steel and can withstand the load of people standing during installation.

[0043] It is worth noting that the entire device is controlled by a main control button. Since the device matched with the control button is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0044] 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.
