Description

Technical Field

[0001] The utility model relates to the technical field of wave-making equipment, in particular to an ocean wave test water tank. Background Art

[0002] Wave making is an important test technology. As an important laboratory device, wave makers occupy an important position in the fields of ships, ports, coastal engineering, and marine engineering. Wave makers are a kind of infrastructure that matches the wave test pool. Its function is to create waves of different wavelengths and wave heights in the test pool, simulate the impact of actual waves on ships or buildings, etc., to measure various technical data, and provide a basis for related designs. At present, most of the wave flumes used in water conservancy engineering scientific research and port river experimental teaching are fixed, made by connecting concrete, steel bars, angle steel and glass putty. The production cycle is long. Once completed, they will be scrapped after disassembly and cannot be installed removably. This form is increasingly unable to meet the current scientific research and teaching needs, and the length of the existing wave maker flume is fixed. The length of the test flume cannot be adjusted according to actual use needs, which is not convenient for simulating different waveforms and is inconvenient to use. Therefore, it needs to be improved. Utility Model Content

[0010] Figure 2 This is a three-dimensional schematic diagram of the middle water tank. DETAILED DESCRIPTION

[0011] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0014] like Figures 1-2As shown, an ocean wave test tank includes a first tank 1, a plurality of intermediate tanks 2 and a final tank 3. The plurality of intermediate tanks 2 are arranged between the first tank 1 and the final tank 3 and are detachably connected to form a straight line. A wave maker is installed in the first tank 1 for making waves in the first tank 1. A wave eliminating device is installed in the final tank 3 for eliminating waves in the final tank 3. The intermediate water tank 2 serves as a transition section of the wave, and includes a frame 21, a panel 22, a guide rail 23 and a track pulley 24. The two panels are mounted on the upper end of the frame 21 in a mirror-symmetrical manner. The two guide rails 23 are mounted side by side between the first water tank 1 and the last water tank 3. The lower end of the frame 21 is movably connected to the guide rail 23 through the track pulley 24. The frame 21 performs reciprocating linear motion along the guide rail 23. The front and rear ends of the frame 21 are respectively provided with a flange 211 and a sealing rubber pad 212. The cross section of the sealing rubber pad 212 is U-shaped. The flanges 211 and the sealing rubber pads 212 of the two adjacent frames 21 are fitted one by one. Specifically, in this embodiment, the first water tank 1 can be directly fixed on the ground, while the last water tank 3 is movable. Several intermediate water tanks 2 are connected in sequence by docking and installed between the first water tank 1 and the last water tank 3, so as to adjust the length of the intermediate water tank 2 according to the needs of the wave-making experiment. In order to prevent water from overflowing from the connection of the middle water tank 2 during wave making, we set flanges 211 and sealing rubber pads 212 at both ends of the frame 21. In this embodiment, the frame 21 is made of aluminum alloy, with high structural strength, light weight and easy to move. Two panels 22 are symmetrically installed on the upper part of the frame 21. The panels 22 cooperate with the bottom of the frame 21 to form a trough with a U-shaped cross section, which is convenient for water to pass through during wave making. The panels 22 are made of glass plates, which are convenient for staff to directly observe the waveform with the naked eye and then adjust the output power of the wave maker. In order to facilitate the displacement of the rack 21, we laid a guide rail 23 on the ground, and installed a track pulley 24 at the bottom of the rack 21, so that the operator can directly move the rack 21 along the guide rail 23, and the guide rail 23 can also play a limiting role, ensuring that the middle water tanks 2 remain in the same straight line without tilting, so that the ends of the front and rear racks 21 are aligned. After the ends of the front and rear racks 21 are aligned, the flange 211 or sealing rubber pad 212 of the front rack 21 cooperates with the sealing rubber pad 212 or flange 211 of the rear rack 21, so that the sealing rubber pad 212 is squeezed and interference fits between the two racks 21 to prevent water from overflowing from the connection of the middle water tank 2. The length of the tank body of the entire experimental water tank is adjustable, which is convenient for adapting to different waveforms for testing, and the test data is more accurate. It is understandable that the abutment between the middle water tank 2 and the first water tank 1 and the last water tank 3 can also be sealed by installing a rubber pad at the connection to prevent water from flowing out.

[0015] like Figures 1-2As shown, the two ends of the frame 21 are also provided with a tightening screw 213 and a plug hole 214, respectively, and the tightening screws 213 of two adjacent frames 21 are correspondingly plugged into the plug holes 214. Specifically, the tightening screw 213 is installed on the end side wall of the frame 21 and is arranged along the length direction of the frame 21. When splicing two intermediate water tanks 2, the ends of the front and rear frames 21 are aligned under the restriction of the guide rail 23, so that the tightening screw 213 can be accurately inserted into the plug hole 214, and then the operator screws the nut to tighten the two frames 21, so that the sealing rubber pad 212 between the two frames 21 is squeezed, interference fit, and stronger sealing.

[0016] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
