Description

Technical Field

[0001] The utility model relates to the technical field of anechoic chambers, in particular to a movable assembled semi-anechoic chamber. Background Art

[0002] The semi-anechoic chamber is an anechoic chamber with the floor as the reflecting surface to simulate a semi-free space. It is designed based on the principle that the fully reflecting ground is used as a mirror to double the effective size. In the semi-anechoic chamber, as long as the sound source is placed on the reflecting ground, that is, when the sound source radiation surface and the ground are in a plane, the sound propagation is the same as in a conventional anechoic chamber. In fact, it is difficult to do this because the sound source has a certain scale, but as long as the sound source is as close to the reflecting surface as possible, when h < r (h is the distance between the sound radiation surface and the ground, and r is the distance between the receiving point and the sound source), the law of sound pressure changing with distance is the same as that in the full anechoic chamber, except that the received sound pressure value is twice that in the free field. Compared with the full anechoic chamber, it is low in cost and easy to use, and is suitable for acoustic testing of bulky industrial equipment and machine structures. The existing anechoic chamber is not easy to move after assembly. If it needs to be used in a designated place, it needs to be disassembled and transported to the designated place for reassembly, which is time-consuming and troublesome.

The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] According to an embodiment of the utility model, a movable assembled semi-anechoic chamber is provided.

[0026] Embodiment 1;

[0027] like Figure 1-6 As shown, the movable assembled semi-anechoic chamber according to the embodiment of the utility model includes a mobile base 1, a semi-anechoic chamber body 2 is provided on the top of the mobile base 1, a sealing door 3 is provided on one side of the semi-anechoic chamber body 2, a mobile component is provided in the mobile base 1, and symmetrically arranged pull rods 4 are provided on both sides of the semi-anechoic chamber body 2, and the pull rods 4 are connected to the semi-anechoic chamber body 2 through a fixed seat 20.

[0028] Embodiment 2:

[0029] like Figure 1-6As shown, it includes a mobile base 1, a semi-anechoic chamber body 2 is provided at the top of the mobile base 1, a sealing door 3 is provided on one side of the semi-anechoic chamber body 2, a mobile assembly is provided in the mobile base 1, and symmetrically arranged pull rods 4 are provided on both sides of the semi-anechoic chamber body 2, and the pull rods 4 are connected to the semi-anechoic chamber body 2 through a fixed seat 20. A plurality of evenly distributed shock-absorbing pads 5 are provided at the bottom end of the mobile base 1, and anti-slip grooves are provided at the bottom end of the shock-absorbing pads 5. The outer walls of the two sets of pull rods 4 are both covered with protective rubber sleeves. The mobile assembly includes a mounting plate 6 provided in the mobile base 1, a plurality of evenly distributed guide rods 7 are provided in the mobile base 1 and penetrate the mounting plate 6, a spring 8 is provided at the top of the mounting plate 6 and on the outer wall of the guide rod 7, the mounting plate 6 is connected to the mobile base 1 through the spring 8, a plurality of evenly distributed mounting frames 9 are provided at the bottom of the mounting plate 6, a roller 10 is provided at the bottom of the mounting frame 9, a guide rail 11 is provided at the top of the mobile base 1, a slide plate 12 matching therewith is provided at the bottom of the guide rail 11, a guide push block 13 is provided at the bottom of the slide plate 12, a plurality of evenly distributed mounting frames 14 are provided at the top of the mounting plate 6, and a roller 15 matching the guide push block 13 is provided at the top of the mounting frame 14. A guide slide hole 16 matching the guide rod 7 is provided at the top of the mounting plate 6. A through hole 17 matching the roller 10 is provided at the bottom of the mobile base 1.

By setting the mobile assembly, it is convenient to move the semi-anechoic chamber without disassembling and transporting it, making it more convenient to use. At the same time, when the semi-anechoic chamber is moved to the designated place, the roller 1 in the mobile assembly can be recovered to the inside of the mobile base, so that the bottom end of the mobile base contacts the ground to prevent sliding, and the use is more stable and safe.

[0031] To sum up, with the help of the above-mentioned technical solution of the utility model, the semi-anechoic chamber can be easily moved by setting up a mobile component, without the need to disassemble and transport it, making it more convenient to use. At the same time, when the semi-anechoic chamber is moved to a designated place, the roller in the mobile component can be recovered to the inside of the mobile base, so that the bottom end of the mobile base is in contact with the ground to prevent sliding, making it more stable and safe to use.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
