Description

Technical Field

[0001] The utility model relates to the technical field of voiceprint recognition equipment, in particular to a front-end voiceprint collection device based on voiceprint recognition technology. Background Art

[0002] Voiceprint recognition can obtain the size of external sounds by converting acoustic signals into electrical signals and then using computers to identify them. Ultrasonic detection is a type of mechanical vibration wave. From the perspective of energy, the process of local discharge is the process of instantaneous energy burst. Electrical energy is released in the form of sound energy, light energy, heat energy and electromagnetic energy. Electrical breakdown occurs in the air gap, and the discharge can be completed instantly. At this time, the electrical energy will also be converted into heat energy in an instant. The gas at the discharge center will expand due to the effect of heat energy and propagate outward through sound waves. The gas in the propagation area is heated to form an isothermal zone, and its temperature exceeds the ambient temperature. In actual testing, due to the high frequency of ultrasound and UHF, the attenuation is very fast. The ultrasonic sensor needs to be well fitted to the corresponding discharge part to reduce the acoustic impedance of ultrasound to meet the sensitivity requirements of the ultrasonic sensor.

[0003] Voiceprint recognition technology is generally reflected in a certain field with the help of specific equipment. Common speech recognition is a type of voiceprint recognition technology. After applying voiceprint recognition technology, it can reduce the cost of inspection and maintenance and manual workload, improve the production capacity of long-term continuous production, truly realize equipment status inspection and optimized maintenance, and improve equipment management and information level.

[0004] Among many mechanical equipment and power equipment, voiceprint recognition technology mainly uses voiceprint recognition sensors as front-end monitoring equipment, so that fault information during the operation of the equipment can be directly displayed on the terminal device through signal transmission. The voiceprint collection device with a voiceprint recognition sensor is mainly connected to the equipment by gluing and magnetic attraction, and uses bone conduction to shield external noise and accurately collect the voiceprint of the main equipment. However, directly sticking or magnetically adsorbing the voiceprint collection device on the equipment is prone to uneven surface conditions at the target equipment installation location and high heat generated during the operation of the equipment. For the bonding and magnetic attraction methods, both affect the stability of the connection, which is not conducive to ensuring the accuracy of the equipment voiceprint collection information. Utility Model Content

[0005] In order to overcome the existing form of directly pasting or magnetically adsorbing the voiceprint collection device on the device, it is easy to affect the stability of the connection due to the uneven surface of the target device installation position and the high heat generated during the operation of the device. For the bonding and magnetic adsorption methods, it is not conducive to ensuring the accuracy of the device voiceprint collection information. The embodiment of the present application provides a front-end voiceprint collection device based on voiceprint recognition technology, by fitting the back of the mounting back plate 2 with the heat dissipation fins of the centrifugal unit motor, so that two assembly strips are respectively inserted between two adjacent fins of the plurality of heat dissipation fins, when the connecting rod is controlled by the control wheel to drive the two threaded rods to rotate, the threaded connection between the two threaded rods and the two support seats is adjusted, the two support seats are pushed away from each other, and the assembly strips are driven to rotate around the first shaft rod, so that the ends of the assembly strips located between the heat dissipation fins are close to each other, and the clamping function is performed, so that the mounting back plate carrying the voiceprint collection device body is fixed on the surface of the centrifugal unit motor housing, which is convenient for the voiceprint collection device body to perform the centrifugal unit voiceprint collection work by bone conduction.

[0023] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0024] Embodiment 1:

[0025] This embodiment introduces a specific structure of a front-end voiceprint collection device based on voiceprint recognition technology. Figure 1-Figure 3 As shown, it comprises a voiceprint collection device body 1, a mounting back plate 2 arranged on the back of the voiceprint collection device body 1, and two assembly strips 5 respectively located inside the two ends of the mounting back plate 2, the inside of the two ends of the mounting back plate 2 are processed with movable notches 4, the middle parts of the two assembly strips 5 are plug-connected with a first shaft rod 6, the inside of one end of the two assembly strips 5 are movably connected with a support seat 9, a connecting rod 11 is arranged between the two support seats 9, and the two ends of the connecting rod 11 are processed with threaded rods 14;

[0026] The two assembly strips 5 are respectively located inside the two movable notches 4, and the two ends of the first shaft rod 6 are pinned to the inside of the mounting back plate 2. For example, when the voiceprint collection device body 1 is installed on the centrifugal unit of the nitrification section, the back of the mounting back plate 2 can be made to fit with the motor heat dissipation fins on the centrifugal unit, and the two assembly strips 5 are respectively inserted between two adjacent fins of the multiple heat dissipation fins;

[0027] At the same time, the two threaded rods 14 are respectively threadedly connected to the inside of the two support seats 9. Since the threads of the two threaded rods 14 are in opposite directions, the threaded connection between the two threaded rods 14 and the two support seats 9 can be adjusted at the same time by controlling the rotation of the connecting rod 11, so that one end of the two assembly strips 5 is away from each other, and the other ends of the two assembly strips 5 are close to each other, so that the two assembly strips are supported by the heat dissipation fins and are clamped on the outside of the motor housing of the centrifugal unit;

[0028] Secondly, in order to facilitate the control of the connecting rod 11 to drive the two threaded rods 14 to rotate, as shown in FIG. Figure 1 and Figure 3 As shown, two limiting cutouts 13 are processed at both ends of the connecting rod 11, and the two limiting cutouts 13 located on the same side are symmetrical about the axis of the connecting rod 11. Both ends of the two connecting rods 11 are pin-connected with control wheels 12 through the two limiting cutouts 13, and the control wheels 12 can facilitate the user to control the rotation of the connecting rod 11;

[0029] Furthermore, in order to limit the rotation of the threaded rod 14 and the support seat 9 when they are connected without external force, Figure 1 and Figure 3 As shown, the outer parts of the two threaded rods 14 are both threadedly connected with locking knobs 10, and by supporting one side of the locking knobs 10 on the surface of the support seat 9, the connection between the connecting rod 11 and the support seat 9 can be prevented from being loosened;

[0030] Furthermore, in order to prevent the support seat 9 from moving inside the assembly strip 5 and affecting the threaded connection between the threaded rod 14 and the support seat 9, as shown in FIG. Figure 1 and Figure 2 As shown, the top and bottom of the support seat 9 are plug-connected with a second shaft rod 8. By pin-connecting one end of the second shaft rod 8 to the inside of the assembly strip 5, the support seat 9 is rotated between the two second shaft rods 8. After the support seat 9 is connected to the assembly strip 5, the threaded rod 14 can still be threadedly connected to the inside of the assembly strip 5.

[0031] By adopting the above technical solution:

[0032] The above design makes the back side of the mounting back plate 2 fit with the heat dissipation fins of the centrifugal unit motor, so that the two assembly strips 5 are respectively inserted between two adjacent fins of the plurality of heat dissipation fins. When the connecting rod 11 is controlled by the control wheel 12 to drive the two threaded rods 14 to rotate, the threaded connection between the two threaded rods 14 and the two support seats 9 can be adjusted, so that the two support seats 9 are pushed away from each other, and the assembly strips 5 are driven to rotate around the first shaft 6.

[0033] At this time, the support seat 9 rotates around the second shaft 8 inside the assembly strip 5, and can adapt to the two rotating assembly strips 5, and the ends of the two assembly strips 5 located between the heat dissipation fins are close to each other, performing a clamping function, so that the mounting back plate 2 carrying the voiceprint collection device body 1 is fixed to the surface of the centrifugal unit motor housing, which is convenient for the voiceprint collection device body 1 to collect the centrifugal unit voiceprint by bone conduction;

[0034] It is worth noting that, in this embodiment, only the case where the voiceprint collection device body 1 is connected to the centrifuge unit motor is exemplified. In the actual application process, it is only necessary to ensure that the device connected to the voiceprint collection device body 1 has a structural part whose size does not exceed the distance between the two assembly strips 5 when they are parallel to each other. When the back of (2) can fit with the device during connection, the voiceprint collection device body 1 can be used to perform voiceprint detection of the target device in the form of bone conduction.

[0035] Embodiment 2:

[0036] Based on Example 1, this example introduces the specific structure of the backboard 2, and two supporting wing plates 3 are processed on one side surface of both ends of the backboard 2;

[0037] The two supporting wing plates 3 are symmetrically distributed on both sides of the movable notch 4. By movably connecting the assembly strip 5 between the two supporting wing plates 3, the assembly strip 5 can be stably rotated around the first shaft 6.

[0038] Secondly, in order to control the range of movement of the assembly strip 5 in the movable slot 4, as Figure 1 As shown, a limit rod 7 is pin-connected between the two supporting wing plates 3 on the same side. The two limit rods 7 are located on the inner sides of the two first shaft rods 6. By making the limit rod 7 form a blockage at one end of the assembly strip 5 close to the connecting rod 11, the movable range of the connecting rod 11 on the front side of the voiceprint collection device body 1 can be limited.

[0039] By adopting the above technical solution:

[0040] The above design processes two supporting wing plates 3 on one side surface of the two ends of the mounting back plate 2, and pins a limit rod 7 between the two supporting wing plates 3. When the connecting rod 11 is controlled to rotate and the threaded connection between the threaded rod 14 and the support seat 9 is adjusted, the limit rod 7 can be used to limit the distance between the ends of the assembly strips 5 located on the front of the voiceprint collection device body 1, thereby controlling the range of rotation of the assembly strips 5 around the first shaft 6 inside the movable slot 4, so as to facilitate the quick placement of one end of the two assembly strips 5 in the gap between the heat dissipation fins on the centrifuge unit motor.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
