Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device for a sound signal sensor. Background Art

[0002] The safe operation of chemical pipeline production equipment is of vital importance, requiring chemical equipment to have normal pressure, flow and other operating conditions. At present, in order to ensure the safe operation of chemical pipeline production equipment, sound signal sensors can be used to diagnose and monitor the internal operation of the pipeline in real time; when a fault occurs, the sound waves in the pipe are abnormal. When the sound waves hit the surface of the sensor, the piezoelectric material inside the sound signal sensor produces a tiny charge change that is converted into a digital signal to issue an early warning.

[0003] At present, the operating environment of chemical pipelines is complex, including high humidity that can easily damage sound signal sensors, and high noise in the production environment, which can interfere with the sensitivity of such sound signal sensors, resulting in tiny digital signal fluctuations that make their use ineffective.

[0004] In summary, it is considered to provide a protective structure for this type of sound signal sensor so that it can improve its protection against moisture, while reducing the interference of external noise; in view of this, we propose a sound signal sensor protection device.

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0030] A sound signal sensor protection device includes an inner mounting shell 4 for mounting a sound signal sensor body 5, and further includes:

[0031] The outer ring shell 1 is arranged outside the inner mounting shell 4 for detachable installation on the pipeline; Figure 1 and Figure 2 In the structure shown, the outer ring shell 1 includes two symmetrically arranged semi-annular structures, one of which is provided with an embedding groove 102, and the other semi-annular structure is provided with an embedding column 103 for rotatably mounting in the embedding groove 102. A rotating shaft 104 is installed between the two semi-annular structures for controlling opening and closing. At the same time, a convex plate 101 is provided for detachably installing the fixing bolts 7, the purpose of which is to obtain a clamping state. In this embodiment, sealing strips are provided on the mating surfaces of the semi-annular structures on both sides, which can improve the sealing of the installation.

[0032] The moisture-proof heat dissipation part is used for heat conduction and cooling and avoiding humidity in the working environment, and includes a heat dissipation unit 3 installed between the outer ring shell 1 and the inner mounting shell 4 and side fixing plates 6 arranged on both sides of the heat dissipation unit 3; the side fixing plates 6 of this embodiment are as shown in FIG. Figure 1 and Figure 2 The structure shown is detachably mounted on the outer ring housing 1 by means of screws.

[0033] The noise reduction silicone plate 2 is arranged between the outer ring shell 1 and the heat dissipation unit 3. The inner side of the outer ring shell 1 is provided with a noise reduction embedding cavity 11 for installing the noise reduction silicone plate 2. The noise reduction silicone plate 2 of this embodiment is provided with a honeycomb hole structure. When the external noise sound wave reaches the noise reduction silicone plate 2, the honeycomb hole structure can greatly weaken the sound wave energy and attenuate the sound wave, thereby avoiding the problem of false alarm caused by vibration of the chemical pipeline network caused by external sound waves. It should be noted that the reason for using silicone material is that silicone also has good thermal conductivity, which can cooperate with the heat dissipation unit 3 to keep the internal temperature of the device stable and avoid high temperature.

[0034] See also Figure 3-Figure 5 The heat dissipation unit 3 comprises two coaxially arranged heat-conducting aluminum plates 31, and uniformly distributed supporting aluminum fins 32 are installed between the two heat-conducting aluminum plates 31; ventilation holes 311 are provided on the heat-conducting aluminum plates 31, and the side fixing plates 6 are detachably installed on both sides of the two heat-conducting aluminum plates 31; a moisture absorption cavity 301 is provided between the side fixing plates 6 and the two heat-conducting aluminum plates 31, and the moisture absorption cavity 301 is filled with dry adsorption material, and this embodiment uses dry color-changing silica gel as a desiccant; in this embodiment, the side fixing plates 6 can play a limiting role, and are detachably installed on both sides of the heat dissipation unit 3, so as to facilitate later replacement, and at the same time, the side fixing plates 6 are detachably installed on the outer ring shell 1 by screws to obtain a mutually fixed state.

[0035] The working principle of the sound signal sensor protection device of this embodiment is as follows: Taking the chemical pipeline network as an example, Figure 5 In the structure shown, dry color-changing silica gel is filled in the moisture absorption cavity 301 and then the side fixing plate 6 is encapsulated. Subsequently, the inner mounting shell 4 in which the sound signal sensor body 5 is installed in the inner mounting cavity 41 is installed to the inner side of the heat dissipation unit 3. The noise reduction silica gel plate 2 is installed in the noise reduction embedding cavity 11. The external noise can largely weaken the sound wave energy through the honeycomb hole structure, so that the sound wave is attenuated, thereby avoiding the problem of false alarm caused by vibration of the chemical pipeline network caused by external sound waves; then the heat dissipation unit 3 is fixedly installed between the side fixing plate 6 and the outer ring shell 1. In order to improve the efficiency of heat exchange with the outside world, the side fixing plate 6 of this embodiment is also made of aluminum profile, which can conduct heat and dissipate heat with the outside air. At the same time, the device has good moisture-proof performance and is easy to disassemble and assemble.
