Description

Technical Field

[0001] The utility model belongs to the technical field of coastal singing sand research, and particularly relates to a coastal singing sand sound exciting device. Background Art

[0002] Coastal singing sand is an extremely rare geological relic and natural landscape. The project team discovered several coastal singing sands along the coast of Hainan Island, filling a gap in research on coastal singing sands in my country. Currently, there is no reference technology or equipment for acoustic stimulation of coastal singing sands, and research in this area is limited. However, there is more research on desert singing sands, some of which have even become tourist attractions. A simple way to identify desert singing sand is to place sand in a wooden bowl and hammer it with a wooden pestle. If the sand in the bowl makes a "gurgling" sound, it is singing sand. If it only makes a friction sound, coastal singing sand can also be identified using this method. However, the sound stimulated by this method is discontinuous, making it difficult to study the acoustic mechanism of coastal singing sands.

[0003] To this end, we propose a coastal chirping sound excitation device to solve the above problems. Utility Model Content

[0015] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0016] See also Figure 1-2 The utility model provides a coastal singing sand sound excitation device, including a cylindrical coastal singing sand cylinder 1 and a manual rotating part. Specifically, a cylindrical column 2 is installed in the center of the interior of the coastal singing sand cylinder 1, and an axis 3 is installed in the center of the top of the column 2. A rotating shaft 6 is sleeved on the axis 3, and a crossbeam 4 is installed at both ends of the rotating shaft 6. A handle 5 is installed at the upper end of the crossbeam 4 on one side, and a scraping plate 7 is installed at the lower end of the crossbeam 4 on the other side. The bottom of the scraping plate 7 has plow teeth 14. Coastal singing sand 15 is filled between the outer periphery of the column 2 and the inner wall of the coastal singing sand cylinder 1. When the crossbeam 4 is manually shaken, the scraping plate 7 is driven to perform a circular motion along the axis 3. Under the pressure and friction of the plow teeth 14 of the scraping plate 7, the coastal singing sand 15 continues to make a "gurgling" sound.

[0017] Among them, the cylinder body, column and axis are integrated and made of fiberglass. The manual rotating part is made of stainless steel. The scraping plate 7 must have a certain weight.

[0018] In addition, the scraper plate 7 is connected to the beam 4 through a hanging plate 9, which passes through the beam 4 and has a slot 13 at one end thereof. The top of the scraper plate 7 has a scraper plate hanging portion 8, and the top of the scraper plate hanging portion 8 is inserted into the slot 13 and fixed by a scraper plate fixing bolt 12. The hanging plate 9 is movable through the beam 4, and the part of the hanging plate 9 at the upper end of the beam 4 is provided with a number of hanging up and down adjustment holes 10 arranged from top to bottom. A hanging fixing bolt 11 is movably passed through one of the hanging up and down adjustment holes 10 to limit the hanging plate 9 on the beam 4, so that the installation height of the scraper plate 7 can be changed.
