Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic pneumatic wave generator, in particular to an automatic pneumatic wave generator applied to the field of wave generator. BACKGROUND

[0002] The wave generator is a device for artificially simulating waves in a laboratory environment, which drives water movement through machinery, hydraulic pressure or air pressure to generate waves of different wavelengths, wave heights and forms. Its core function is to reproduce the marine wave environment to provide controllable physical simulation conditions for model tests in the fields of ships, coastal engineering and offshore platforms. The wave generator can generate regular waves (such as sine waves and elliptical cosine waves) and irregular waves (based on P-M spectrum and B spectrum), covering wave forms from light wind to extreme typhoon weather. By simulating the impact of waves on structures such as ships, breakwaters and wharfs, key data such as fluid dynamic parameters and structural stability can be measured to provide a basis for engineering design and support mooring tests, seakeeping tests, coastal erosion prevention research and reliability testing of offshore resource development facilities.

[0003] The wave generator has become the core equipment of the marine engineering laboratory, ensuring the scientificity, safety and economy of engineering design.

[0004] Currently, the existing automatic pneumatic wave generator does not have a protection mechanism when it is moved to the use position, so it is difficult to protect the outer end and internal elements when it collides with external objects, which can easily damage the outer end and internal elements. UTILITY MODEL CONTENT

[0005] In view of the above prior art, the technical problem to be solved by the utility model is that the existing automatic pneumatic wave generator is difficult to protect the outer end and internal elements when it collides with external objects during movement.

[0007] In the above-mentioned automatic pneumatic wave generator, the outer end of the wave generator body and its internal elements can be protected, so that they are not easily damaged by collision with external objects, thereby improving the service life of the wave generator body.

[0011] As a further improvement of the present application, the ends of the threaded pipes away from each other are fixedly connected with screwing pipes, and the outer end of the screwing pipe is provided with anti-skid lines.

[0012] As a further improvement of the present application, the upper and lower ends of the insertion rod are provided with a plurality of outer end grooves, and the inner part of the outer end groove is rotatably connected with a ball.

[0013] As a further improvement of the present application, the outer end of the insertion rod is fixedly connected with a pair of connecting blocks, the upper and lower ends of the connecting block are fixedly connected with scrapers, the conical end of the scraper is in contact with the inner wall of the moving track, and the upper and lower ends of the insertion rod are flush with the end of the scraper with the conical surface.

DETAILED DESCRIPTION

[0023] The two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0024] First embodiment:

[0025] Figures 1-5 An automatic pneumatic wave generator is shown, which comprises a wave generator body 1, a moving track 2 is formed at the outer end of the wave generator body 1, an plug-in rod 3 is rotatably connected inside the moving track 2 by an electric roller, an electric push rod 4 is fixedly connected to the side end of the plug-in rod 3, a mounting block 5 is fixedly connected to the telescopic end of the electric push rod 4, a sleeve plate 6 is movably sleeved at the outer end of the mounting block 5, and a rubber plate 7 is fixedly connected to the end of the sleeve plate 6 away from the mounting block 5;

[0026] A mounting groove 8 movably inserted with the mounting block 5 is formed at the side end of the sleeve plate 6, the plug-in rod 3 is in contact with the moving track 2, a pair of reinforcing grooves 9 are formed on the inner wall of the mounting groove 8, and a reinforcing block 10 movably inserted with the reinforcing groove 9 is fixedly connected to the upper and lower ends of the mounting block 5;

[0027] After the sleeve plate 6 is sleeved on the mounting block 5, the reinforcing block 10 will enter the reinforcing groove 9, and the sleeve plate 6 is limited by the reinforcing block 10, preventing the sleeve plate 6 from rotating on the mounting block 5;

[0028] A pair of threaded pipes 11 are threadedly connected inside the sleeve plate 6, a limiting groove 12 threadedly connected with the threaded pipe 11 is formed at the end of each of the pair of reinforcing blocks 10 away from each other, and a twisting pipe 13 is fixedly connected to the end of each of the pair of threaded pipes 11 away from each other;

[0029] When the sleeve plate 6 and the rubber plate 7 are damaged and need to be removed for maintenance or replacement, the twisting pipe 13 needs to be manually rotated to drive the threaded pipe 11 to rotate together, so that the threaded pipe 11 is removed from the sleeve plate 6 and the reinforcing block 10, thereby releasing the limiting of the threaded pipe 11 to the sleeve plate 6, and then the sleeve plate 6 is removed from the mounting block 5, and the sleeve plate 6 and the rubber plate 7 can be maintained or replaced;

[0030] The outer end of the twisting pipe 13 is engraved with anti-skid lines, and the upper and lower ends of the insertion rod 3 are provided with a plurality of outer end grooves, and the inner ends of the outer end grooves are rotatably connected with the balls 14. By using the balls 14, the frictional force suffered by the insertion rod 3 when moving in the moving track 2 can be reduced.

[0031] The application is divided into the following steps when in use:

[0032] Step one: when in use, during the process of pushing the wave generator body 1 to move to the use position, the electric push rod 4 can be started to push the mounting block 5, the sleeve plate 6 and the rubber plate 7 to move away from the wave generator body 1, thereby adjusting the distance between the mounting block 5, the sleeve plate 6, the rubber plate 7 and the wave generator body 1;

[0033] When moving, the sleeve plate 6 and the rubber plate 7 not only can protect the wave generator body 1, but also can buffer external force, so as to protect the outer end of the wave generator body 1 and the internal elements, so as not to be easily damaged by collision with external objects, thereby prolonging the service life of the wave generator body 1;

[0034] Step two: when in use, the electric roller can be started according to the forward direction of the wave generator body 1 to drive the insertion rod 3 and all the mechanisms connected therewith to rotate around the wave generator body 1 until the sleeve plate 6 and the rubber plate 7 are moved to the position consistent with the moving direction of the wave generator body 1, and then the operation in step one is repeated to protect the wave generator body 1 by the sleeve plate 6 and the rubber plate 7, thereby improving the flexibility of the protection mechanism and facilitating the use of personnel when moving the wave generator body 1.

[0035] Second embodiment:

[0036] Based on the first embodiment, the following structure is added, and the remaining parts remain the same as the first embodiment, which is as follows:

[0037] Figure 3 The outer end of the insertion rod 3 is fixedly connected with a pair of connecting blocks 15, the upper and lower ends of the connecting blocks 15 are fixedly connected with scraper plates 16, the tapered end of the scraper plate 16 is in contact with the inner wall of the moving track 2, and the upper and lower ends of the insertion rod 3 are flush with one end of the scraper plate 16 with a taper.

[0038] The electric roller is started, and the plug rod 3 drives the scraper 16 to move along the inner wall of the moving track 2 during the movement of the plug rod 3 in the moving track 2, and the end with the tapered surface is used for scraping the foreign matters and dust adhered to the top wall and the bottom wall of the moving track 2, so that the cleanliness of the inner wall of the moving track 2 is improved, and the inconvenience caused by the large amount of dust and foreign matters adhered to the inner wall of the moving track 2 to the movement of the plug rod 3 is reduced.

[0039] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to the above, and various changes made within the knowledge range of the skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
