[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0018] The invention is described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0019] like Figure 1-2 As shown, a sound wave signal simulation device. The circuit board box 2 is combined with the shell component 3 by welding to form a metal body. The circuit board box 2 is provided with a threading hole to facilitate the wiring of the internal cables. The end cover 1 is fixed to the shell component 3 by threads to form a sealed body with dustproof and waterproof functions. The electromagnet 10 is installed in the inner cavity of the shell component 3 and fixed to the shell component 3 by fastening screws 15.

[0020] The compression spring 4 and the piston 5 are installed in the piston sleeve 8. During installation, the outer surface of the piston is coated with lubricating oil to reduce the wear of the piston 5 during movement. The compression spring 4 is sleeved on the striker 11. The compression spring 4 serves to buffer the instantaneous impact of the striker 11 on the piston 5 and improve the life of the piston 5. The precision fastening nut 9 is used to adjust the verticality of the striker 11 and the piston sleeve 8 to ensure that the striker 11 moves up and down without jamming.

[0021] The O-ring 7 is sleeved on the outermost end of the piston 5, playing the role of the first layer of sealing. The sealing ring 6 is sleeved on the inner end of the piston 5, playing the role of the second layer of sealing, so as to completely isolate the external liquid from entering the piston sleeve 8 under pressure. The external mounting interface of the piston sleeve 8 can be processed into different interfaces such as internal threads and external threads according to user needs. The adjusting screw 16 can fine-tune the gap in the piston sleeve 8.

[0022] The control module 12 receives the control command and controls the electromagnet 10 to work. The control cable is connected to the circuit board box 2 through the connector 14 and connected to the wiring terminal 13 to connect to the control module 12, which is convenient for disassembly and maintenance. The present invention is fixed on the pipe network through the installation interface of the piston sleeve 8, and a test liquid of 0.3-1.5MPa is injected into the pipe network. The piston 5 slides to the bottom of the present invention under the pressure of the liquid, and the test liquid is under pressure at the top of the piston 5. When it is necessary to simulate a sound wave signal, the user issues a control instruction, and the control module 12 receives the control instruction, and the driving electromagnet 10 generates an electromagnetic force of 12Kg after being energized, and drives the striker 11 to accelerate forward movement by 35mm, pushing the piston 5 to move forward instantly, and compressing the liquid to move forward, thereby generating a sound wave signal.

[0023] The electrical interface design of the control module 12 includes a 4-20mA current interface, a 0-5V voltage interface, an RS232 interface, and an RS485 interface. The user can change the size of the current or voltage signal, change the electromagnetic force of the electromagnet 10, and thus change the impact force of the striker 11, so as to facilitate the adjustment of the strength of the simulated sound wave signal.

[0024] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the patent and protection scope of the present invention shall be subject to the attached claims.
