Description

Technical Field

[0001] This utility model relates to the field of voiceprint acquisition technology, and in particular to the installation components of voiceprint acquisition equipment for hydropower stations. Background Technology

[0002] In the daily operation and maintenance of hydropower stations, real-time monitoring of the operating status of core rotating equipment such as large hydro-turbine generator units is a key link in ensuring the safe production of the power station and implementing predictive maintenance. Acoustic fingerprinting, as a non-contact online monitoring technology, can effectively diagnose early faults and potential defects of equipment by collecting and analyzing the acoustic signals generated during equipment operation.

[0003] Effective acoustic signature acquisition requires the acoustic signature collector to be securely installed near the device under test. Existing mounting components typically employ bracket structures with fixed mounting holes. However, in the actual installation environment of hydropower stations, the pre-drilled mounting holes on the wall or frame often deviate from the holes on the mounting component itself. This makes alignment during installation extremely inconvenient, requiring repeated adjustments or even re-drilling, increasing installation difficulty and extending working time. Furthermore, to ensure the signal-to-noise ratio of the acquired signal, the acoustic signature collector needs to be precisely aligned with a specific sound source. The strong mechanical vibrations generated by the hydropower station's generating units during operation will continuously impact the angle locking structure of the mounting component. Some existing components using single bolt fastening or simple friction locking have limited locking torque and may loosen under long-term vibration, causing the acoustic signature collector's acquisition angle to shift. This reduces the accuracy of the acquired acoustic signature signal, directly affecting the reliability of fault diagnosis.

[0004] Therefore, this utility model proposes an installation component for hydropower station acoustic signature acquisition equipment to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems existing in the installation components of hydropower station acoustic fingerprint acquisition equipment, such as inconvenience in adjusting when dealing with the deviation of the reserved hole position on the installation surface, installation difficulties, and insufficient reliability of the angle locking structure under vibration environment, which easily leads to the deviation of the acquisition angle, this utility model aims to provide an improved installation component of hydropower station acoustic fingerprint acquisition equipment that can effectively solve the above problems.

[0006] This utility model provides an installation assembly for a hydropower station acoustic signature acquisition device, including: a support frame, an acoustic signature acquisition device mounted on the support frame, a fixing mechanism, and an angle adjustment mechanism.

[0007] The fixing mechanism has a two-dimensional adjustment structure composed of a sliding groove and multiple positioning grooves, and the angle adjustment mechanism has a toothed disc engagement locking structure controlled by threaded transmission.

[0008] Furthermore, the fixing mechanism includes a mounting plate fixedly connected to the rear side of the support frame. The mounting plate has a sliding groove and multiple positioning grooves. The fixing mechanism also includes a washer with a positioning block and a screw. The positioning block slides in conjunction with the positioning groove, and the screw passes through the washer and can slide within the sliding groove. The angle adjustment mechanism includes a rotating rod that passes through a rotating groove on the voiceprint collector. A gear plate is fixedly connected to the side wall of the voiceprint collector. The rotating rod has a threaded groove. The angle adjustment mechanism also includes a tooth cover and a rotating wheel. The tooth cover and the rotating wheel are fitted onto the rotating rod. The inner wall of the tooth cover has a tooth groove that engages with the gear plate. The rotating wheel is threadedly connected to the threaded groove through an internal thread. The rotating wheel axially abuts against and drives the tooth cover, so that by rotating the rotating wheel, the tooth cover moves axially along the rotating rod, thereby controlling the engagement or disengagement of the tooth groove and the gear plate.

[0009] Preferably, the mounting plate has a vertically oriented groove inside, and multiple sets of positioning grooves are formed horizontally on the front side of the mounting plate. The gasket is located on the front side of the mounting plate, and a positioning block fixedly connected to the rear side of the gasket can selectively engage with different positioning grooves. The screw detachably passes through the gasket and the groove to fix the mounting plate to the mounting surface.

[0010] Preferably, the toothed disc is fixedly connected to the right side of the voiceprint collector, and the right end of the toothed cover is rotatably connected to the left end of the rotating wheel. The tooth grooves on the inner wall of the toothed cover match the tooth profile of the toothed disc to provide angular locking in the meshing state. Rotation slots are provided on both the left and right sides of the voiceprint collector, and the rotating rod passes through the rotation slots on both sides, allowing the voiceprint collector to rotate around the axis of the rotating rod. Preferably, a threaded groove is provided on the right side surface of the rotating rod.

[0011] This utility model has the following beneficial effects: 1. This utility model solves the problem of difficulty in aligning and inconvenient installation of the installation components when there is a deviation in the reserved hole position on the installation surface in the prior art. It is achieved by setting a sliding groove that can slide in the vertical direction and multiple positioning grooves that can be positioned in sections in the horizontal direction, and by coordinating with sliding screws and washers for adjustment.

[0012] 2. This utility model solves the problems of insufficient locking force and easy deviation of the acquisition angle due to vibration in the existing angle adjustment mechanism in high vibration environments such as hydropower stations. It achieves stable and reliable angle locking, effectively resists vibration interference, and ensures that the voiceprint collector maintains a precise acquisition angle for a long time, thereby improving the accuracy of voiceprint acquisition.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] Example: Please refer to Figures 1 to 5This utility model provides an installation component for a hydropower station acoustic signature acquisition device, which aims to solve the problems in the prior art where the installation component is inconvenient to adjust when there are deviations in the reserved holes on the installation surface, and the angle locking structure is not reliable enough under vibration environment.

[0017] like Figure 1 and Figure 2 As shown, the hydropower station acoustic signature acquisition equipment installation assembly includes a support frame 4 and an acoustic signature collector 1 mounted on the support frame 4. The assembly also includes a fixing mechanism 3 for fixing the entire device to the mounting surface and an angle adjustment mechanism 2 for adjusting the acquisition angle of the acoustic signature collector 1. The support frame 4 serves as the installation foundation and support platform for the entire device. The acoustic signature collector 1 is used to acquire sound signals from the target sound source. The fixing mechanism 3 includes a mounting plate 301 fixedly connected to the rear side of the support frame 4. A vertical groove 306 is formed inside the mounting plate 301. Multiple positioning grooves 302 are formed horizontally on the front side of the mounting plate 301. Screws 305 are slidably connected within the grooves 306. The screws 305 detachably pass through a washer 303 and the grooves 306. The washer 303 is located on the front side of the mounting plate 301. A positioning block 304 is fixedly connected to the rear side of the washer 303. The positioning block 304 slides in cooperation with the positioning groove 302 on the front side of the mounting plate 301, and the positioning block 304 can selectively engage. Within different positioning slots 302, the angle adjustment mechanism 2 includes a rotating rod 201. Rotating slots 202 are provided on both the left and right sides of the voiceprint collector 1. The rotating rod 201 passes through the rotating slots 202 on both sides of the voiceprint collector 1, allowing the voiceprint collector 1 to rotate around the axis of the rotating rod 201. A gear plate 203 is fixedly connected to the right side of the voiceprint collector 1. A threaded groove 206 is provided on the right surface of the rotating rod 201. A gear cover 204 and a rotating wheel 207 are fitted onto the rotating rod 201. The inner wall of the gear cover 204 is... A toothed groove 205 is provided, which matches the tooth profile of the toothed disc 203 to provide angular locking in the meshing state. The rotating wheel 207 is threadedly connected to the threaded groove 206 on the rotating rod 201 through an internal thread. At the same time, the left end of the rotating wheel 207 is rotatably connected to the right end of the toothed cover 204, and the rotating wheel 207 axially abuts against and drives the toothed cover 204. By rotating the rotating wheel 207, the toothed cover 204 moves axially along the rotating rod 201, thereby controlling the meshing or disengagement of the toothed groove 205 and the toothed disc 203.

[0018] Please refer to Figure 1 and Figure 5The fixing mechanism 3 includes a mounting plate 301 fixedly connected to the rear side of the support frame 4. The mounting plate 301 has a sliding groove 306 extending in the vertical direction, and multiple positioning grooves 302 are arranged in a horizontal array on the front side of the mounting plate 301. The mounting plate 301 serves as the interface base for connecting the entire device to the mounting surface. The fixing mechanism 3 also includes a gasket 303. The rear side of the gasket 303 is integrally formed or fixedly connected to a positioning block 304. The shape and size of the positioning block 304 are adapted to the positioning grooves 302. The fixing mechanism 3 further includes a screw 305 for final locking. The shank of the screw 305 passes through the central through hole of the gasket 303 and the sliding groove 306 of the mounting plate 301 in sequence.

[0019] In the assembled and adjusted state, the gasket 303 forms a sliding fit with the multiple positioning grooves 302 on the front side of the mounting plate 301 through the positioning block 304 on the rear side. The operator can insert the positioning block 304 into different positioning grooves 302 to achieve coarse adjustment of the horizontal position of the mounting component. At the same time, the screw 305 together with the gasket 303 can slide freely within the length range of the slide groove 306 to achieve fine adjustment of the vertical position of the mounting component. This two-dimensional adjustable mounting structure, composed of horizontally separate positioning grooves 302 and vertically continuous slide grooves 306, ensures that the mounting component of the hydropower station acoustic fingerprint acquisition equipment can be accurately aligned with the reserved mounting holes on the mounting surface during installation, which greatly improves the convenience of installation and adaptability to on-site working conditions. Finally, by tightening the screw 305, the head of the screw 305 presses the gasket 303 and locks the positioning block 304 of the gasket 303 in the positioning groove 302, achieving a firm and reliable fixation.

[0020] To achieve flexible adjustment and high-strength locking of the angle of the voiceprint collector 1, the angle adjustment mechanism 2 in this embodiment adopts a specific structural design, please refer to... Figure 1 , Figure 3 and Figure 4 The voiceprint collector 1 has rotating slots 202 on both its left and right sides. A rotating rod 201 passes through the rotating slots 202 on both sides of the voiceprint collector 1, thus forming a rotating connection, allowing the voiceprint collector 1 to rotate around the axis of the rotating rod 201. A gear disk 203 is fixedly connected to the right side of the voiceprint collector 1. Multiple locking teeth are evenly distributed along the circumference on the gear disk 203. A threaded groove 206 is provided on the right side surface of the rotating rod 201. A toothed cover 204 and a rotating wheel 207 are rotatably fitted onto the rotating rod 201. A toothed groove 205 matching the tooth shape of the gear disk 203 is provided on the inner wall of the toothed cover 204. The rotating wheel 207 forms a threaded transmission engagement with the threaded groove 206 on the rotating rod 201 through its internal threaded structure. At the same time, a rotating connection is formed between the right end of the toothed cover 204 and the left end of the rotating wheel 207, so that when the rotating wheel 207 rotates, it can axially push or pull the toothed cover 204, but does not transmit rotational torque.

[0021] To further clarify the structural layout of mounting plate 301 and optimize the ease of installation and adjustment, please refer to... Figure 5 The slide groove 306 on the mounting plate 301, which is vertically opened along the central axis, is a long strip-shaped through groove. Multiple positioning grooves 302 on the front side of the mounting plate 301 are opened at equal or unequal intervals along the horizontal direction. This layout makes the horizontal adjustment have clear gears, while the vertical adjustment is more continuous and smooth.

[0022] To ensure the reliability of angle locking, please refer to... Figure 4 The tooth groove 205 on the inner wall of the tooth cover 204 is fully engaged with the outer edge tooth profile of the tooth disk 203. In the meshing state, there is no relative rotational gap between the tooth cover 204 and the tooth disk 203, thereby providing a stable angular locking force and effectively resisting the influence of external vibration on the angle and attitude of the voiceprint collector 1.

[0023] Working principle: When the acoustic fingerprint acquisition equipment installation components of a hydropower station need to be installed on a preset mounting surface, the operator can first slide the shim 303 along with the positioning block 304 on the front side of the mounting plate 301 horizontally, inserting the positioning block 304 into the positioning groove 302 that best matches the horizontal position of the reserved hole on the mounting surface, thus completing the rough adjustment of the installation position in the horizontal direction. Subsequently, within the effective stroke range of the slide groove 306, the operator can drive the screw 305 and the shim 303 to slide up and down as a whole, realizing the vertical adjustment of the installation position. Continuous fine-tuning in the vertical direction until the screw 305 is completely aligned with the reserved mounting hole on the mounting surface. After alignment, the screw 305 is passed through the washer 303 and the slide 306 and screwed into the mounting hole. Tightening the screw 305 will use the pressure applied by the head of the screw 305 to the washer 303 to firmly fix the mounting plate 301 and the support frame 4 to the mounting surface. Through the synergistic action of the positioning groove 302 and the slide 306 in the fixing mechanism 3, the problem of difficult installation alignment and poor adaptability caused by the deviation of the mounting hole position in the prior art is solved.

[0024] After installation, when adjusting the acquisition angle of the voiceprint collector 1, the operator rotates the rotating wheel 207 counterclockwise. Based on the principle of threaded transmission, the rotating wheel 207, through its threaded engagement with the threaded groove 206 on the rotating rod 201, moves to the right along the axis of the rotating rod 201. Since the rotating wheel 207 axially abuts against and drives the toothed cover 204, this axial movement further pushes the toothed cover 204 to move synchronously to the right. This causes the toothed groove 205 on the inner wall of the toothed cover 204 to separate from the toothed disc 203 fixed to the side wall of the voiceprint collector 1, thus releasing the toothed surface engagement lock between them. At this point, the voiceprint collector 1 can freely rotate around the axis of the rotating rod 201 through the rotating pair formed by the rotating groove 202 and the rotating rod 201. The operator can adjust the posture of the voiceprint collector 1 to a predetermined angle that is precisely aligned with the sound source to be measured. After the adjustment is in place, the operator rotates the rotating wheel 207 clockwise. The rotating wheel 207 will move axially to the left along the threaded groove 206, thereby pushing the tooth cover 204 to reset to the left. This allows the tooth groove 205 on the inner wall of the tooth cover 204 to re-engage with the tooth profile of the tooth disk 203. Through the surface contact locking between the teeth, a strong angular locking torque is formed, thereby firmly locking the collection angle of the voiceprint collector 1 at the current position. Through the angle adjustment mechanism 2, the strong mechanical vibration present in the hydropower station environment is effectively resisted, solving the problem of unstable angle locking structure in the existing technology, which is prone to vibration causing the collection angle to shift and thus causing inaccurate voiceprint monitoring data.
