The fixing component 2 includes a fixing belt 21 arranged on the surface of the fixed shell 11, and a fixing head 22 arranged at the end of the fixing belt 21. The fixing belt 21 can be a common linen bandage, and the fixing head 22 can also be a locking structure on a common belt. When the acoustic emitter needs to be fixed, the mounting base 1 can be tied to the rock as a whole via the fixing belt 21 to achieve rapid fixation of the acoustic emitter.

[0031] The surface of the fixed shell 11 is provided with a plurality of limiting grooves adapted to the fixing belt 21 , and the mounting shell 12 is located at a position on the surface of the fixed shell 11 away from the limiting grooves. The surface of the mounting shell 12 is provided with an opening communicating with the outside at a position away from the limiting grooves.

[0032] Further, such as Figure 3 As shown, the limiting grooves provided on the surface of the fixed shell 11 are generally strip-shaped, and all the limiting grooves coincide at the center of the top surface of the fixed shell 11. The number of limiting grooves can be adjusted according to actual needs. The number of limiting grooves is preferably two. In order to facilitate the connection of the sound emitter with the external control equipment after installation, the mounting shell 12 and the fixed shell 11 are both provided with openings for the sound emission device connection line to pass through, and the surface of the fixing belt 21 is provided with an opening adapted to the connection line.

[0033] In some embodiments, to facilitate replacement of the base structure 13, the surface of the mounting shell 12 is provided with threads, the interior of the fixed housing 11 is provided with thread grooves adapted to the threads on the surface of the mounting shell 12, and the interior of the mounting shell 12 is provided with a load-bearing plate 3 for the operator to bear the force when removing the mounting shell 12.

[0034] Specifically, the base pad structure 13 adopted in the present invention includes a connecting plate 131 arranged on the surface of the fixed shell 11 near the opening of the mounting shell 12, a connecting structure connecting the connecting plate 131 and the fixed shell 11, and a soft pad 132 arranged on the connecting plate 131.

[0035] In other embodiments, in order to adapt to the uneven surface of the rock, the number of connecting plates 131 and soft pads 132 is greater than or equal to two, and all the connecting plates 131 and soft pads 132 can form a complete frame structure on the surface of the fixed shell 11. The connecting structure includes a mounting protrusion provided on the connecting plate 131, and a mounting groove provided on the surface of the fixed shell 11 and adapted to the mounting protrusion. Preferably, the surface of the mounting protrusion is provided with a thread, and after all are spliced ​​together, a circular frame structure can be formed, which can be installed into the surface of the fixed shell 11.

The operator can deflate the soft pad 132 at different positions by deflation, thereby changing its support height and further adapting to the protrusions on the rock surface.

[0037] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0039] It should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the technical product is usually placed when in use. They are only for the convenience of describing this technology and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as a limitation on this technology.

[0040] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
