Description

Technical Field

[0001] This application relates to the field of acoustic signature acquisition equipment technology, specifically to an acoustic signature sensor bracket with a vibration damping structure. Background Technology

[0002] Pumps are commonly used mechanical devices that transport or pressurize fluids, playing a vital role in agricultural and urban industrial water supply. During operation, pumps emit sound patterns, and the characteristics of these sound patterns can reflect different operating states of the unit, providing important information for unit condition monitoring.

[0003] In the process of pump acoustic fingerprint measurement, multiple acoustic fingerprint collectors need to be set up for multi-point measurement. The acoustic fingerprint collectors need to be set at a certain height according to the size of the pump. Existing acoustic fingerprint collectors are generally installed on brackets, but the existing brackets have poor vibration reduction effect. The vibration generated by large pump sets can easily be transmitted to the brackets through the ground, causing the acoustic fingerprint collectors to vibrate to a certain amplitude when performing acoustic fingerprint measurements, thus affecting the measurement accuracy of the acoustic fingerprint collectors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a soundprint sensor bracket with a vibration-damping structure, which has advantages such as good vibration reduction effect and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a soundprint sensor bracket with a vibration damping structure, including a tripod, a fixing tube vertically fixedly connected to the top of the tripod, a lifting rod threadedly connected to the top of the fixing tube along its axis, a mounting plate horizontally provided at the top of the lifting rod, and the mounting plate and the lifting rod being rotatably connected through a damping shaft. The top of the mounting plate is fixedly connected to a threaded sleeve along its length, and a threaded tube is threadedly connected inside the threaded sleeve. A vibration damping component is installed inside the threaded tube along its axis. One end of the vibration damping component is provided with a mounting bracket, and a sound pattern collector is installed on one side of the mounting bracket. The vibration damping assembly includes a rubber tube, which is fixedly connected to the inner wall of a threaded tube. Both ends of the rubber tube extend out of the two ends of the threaded tube. A vibration damping rod is slidably inserted inside the rubber tube. Both ends of the vibration damping rod are fixedly connected to vibration damping discs. The two vibration damping discs are fixedly connected to the two ends of the rubber tube. Springs are fixedly connected between the two vibration damping discs and the two ends of the threaded tube. Both springs are sleeved on the outside of the rubber tube. Preferably, the damping disc and the damping rod are detachably and fixedly connected. This arrangement facilitates the insertion of the damping rod into the rubber tube.

[0006] The rubber tube is inlaid with a set of radially spaced, ring-shaped damping elements. Each radial damping element is arranged along the length of the rubber tube, and the length of the radial damping element is equal to the length of the threaded tube. The mounting bracket is rotatably connected to its corresponding vibration damping disc.

[0007] Furthermore, an adsorption rod is slidably sleeved at the bottom end of the fixed tube along its axis, and a suction cup is fixedly installed at the bottom end of the adsorption rod.

[0008] With the above solution, since the indoor floor of the pump station is flat and coated with epoxy resin paint, the suction cup can be firmly attached to the ground, preventing the tripod from tipping over and causing accidents.

[0009] Furthermore, two handles are radially fixedly installed at the top end of the adsorption rod, and two radially arranged screws are threadedly connected to the top end of the adsorption rod.

[0010] The above solution, with the handle, allows users to easily press down the suction cup to fix the tripod. After fixing or unfixing, turning the screw to make tight contact with the fixing tube can lock the suction rod and prevent the suction cup from sliding off when the tripod is moved.

[0011] Furthermore, an air valve is installed on the surface of the suction cup.

[0012] With the above method, when it is necessary to remove the tripod, the suction cup can be easily removed by opening the air valve to release the air inside the suction cup.

[0013] Furthermore, the two ends of the rubber tube extending from the threaded tube are corrugated.

[0014] The above scheme involves creating annular corrugated grooves on the inner wall and outer surface of the rubber tube. When subjected to axial vibration, the damping disc at one end of the damping rod compresses the spring, while the damping disc at the other end of the damping rod compresses the spring. Simultaneously, the compression and stretching of the corrugated section of the rubber tube produces a damping effect, effectively absorbing axial vibration energy.

[0015] Furthermore, the inner wall of the rubber tube has an annular cavity coaxial with the rubber tube. The set of radially spaced radial damping elements are located in the annular cavity. The radial damping elements include two arc-shaped fixing plates. One arc-shaped fixing plate is fixedly connected to the inner wall of the outer ring forming the annular cavity, and the other arc-shaped fixing plate is fixedly connected to the inner wall of the inner ring forming the annular cavity. Two C-shaped elastic plates are arranged between the two arc-shaped fixing plates. The two C-shaped elastic plates are symmetrically arranged, and the openings of the two C-shaped elastic plates are opposite to each other. The two C-shaped elastic plates are integrally formed from spring steel material.

[0016] Through the above scheme, when subjected to radial vibration force, the squeezed rubber tube produces a damping effect, and at the same time, the C-shaped elastic sheet undergoes elastic deformation to further absorb radial vibration energy.

[0017] Furthermore, a throttle is fixedly connected to the outer surface of both the threaded tube and the lifting rod.

[0018] The above solution makes it easier for users to adjust the height of the voiceprint collector off the ground and the distance between it and the device, thus improving the convenience of installation and adjustment.

[0019] Furthermore, a first laser rangefinder, which is vertically downward, is installed at one end of the mounting plate, and a second laser rangefinder, which is horizontally arranged along the radial direction of the fixed tube, is installed on one side of the mounting bracket.

[0020] The above scheme makes it easier for users to determine the height of the voiceprint collector above the ground and the distance between it and the device, ensuring compliance with measurement specifications and improving the accuracy and standardization of measurements.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This acoustic sensor bracket with a vibration damping structure features a rubber tube extending from the threaded tube in the vibration damping assembly, with corrugated ends. When subjected to axial vibration, the damping disc at one end of the damping rod compresses the spring, while the damping disc at the other end compresses the spring. Simultaneously, the corrugated section of the rubber tube is compressed and stretched, generating a damping effect. This effectively absorbs axial vibration energy and reduces the impact of axial vibration on the acoustic sensor. The radial damping component embedded inside the rubber tube consists of two arc-shaped fixed plates and two symmetrically arranged, oppositely spaced C-shaped elastic plates. The C-shaped elastic plates are integrally formed from spring steel. When subjected to radial vibration, they compress the rubber tube, generating a damping effect, while the C-shaped elastic plates undergo elastic deformation, further absorbing radial vibration energy. This comprehensively reduces vibration interference on the acoustic sensor, ensuring that the acoustic sensor is unaffected by vibration during measurement and improving measurement accuracy.

[0022] The suction rod, which is slidably connected to the bottom of the fixed tube, has a suction cup installed at its bottom. Because the floor of the pump station is flat and coated with epoxy resin paint, the suction cup can be firmly attached to the ground, preventing the tripod from tipping over and causing accidents. The handle at the top of the suction rod allows the user to press down on the suction cup to fix it. After fixing or unfixing, turning the screw connected to the threaded end at the top can make it tightly contact the fixed tube, which can lock the suction rod and prevent the suction cup from sliding off when the tripod is moved. The air valve installed on the surface of the suction cup can be opened to release the air in the suction cup when it is necessary to release the tripod fixation, so that the suction cup can be easily removed. The operation is convenient and stable.

[0023] The handle fixed to the outer surface of the threaded pipe and lifting rod allows users to easily adjust the height of the acoustic fingerprint collector from the ground and the distance between it and the equipment, improving the convenience of installation and adjustment. It enables quick adjustment of the acoustic fingerprint collector's position according to actual measurement needs. The first laser rangefinder, vertically downward mounted on one end of the mounting plate, and the second laser rangefinder, horizontally positioned along the radial direction of the fixed pipe and mounted on one side of the mounting bracket, facilitate users in determining the height of the acoustic fingerprint collector from the ground and the distance between it and the equipment. This ensures that the measurement process complies with regulations, improves the accuracy and standardization of measurements, and provides more reliable data support for pump acoustic fingerprint measurement.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figures 1-6This embodiment of a soundprint sensor bracket with a vibration damping structure includes a tripod 1. A fixing tube 2 is vertically fixed to the top of the tripod 1. A lifting rod 3 is threadedly connected to the top of the fixing tube 2 along its axis. A mounting plate 4 is horizontally mounted on the top of the lifting rod 3. The mounting plate 4 and the lifting rod 3 are rotatably connected via a damping shaft. A threaded sleeve 5 is fixedly connected to the top of the mounting plate 4 along its length. A threaded tube 6 is threadedly connected inside the threaded sleeve 5. A vibration damping component 7 is installed inside the threaded tube 6 along its axis. The damping shaft and its connection method are existing technologies and will not be described further here. For example, the damping shaft structure and connection method described in patent publication number CN223677708U, entitled "An Extended Solar Warning Light," can be referenced.

[0028] A mounting bracket 17 is provided at one end of the vibration damping component 7, and a soundprint collector 18 is installed on one side of the mounting bracket 17. The vibration damping component 7 includes a rubber tube 701, which is fixedly connected to the inner wall of the threaded tube 6. Both ends of the rubber tube 701 extend out of the two ends of the threaded tube 6. A vibration damping rod 702 is slidably inserted inside the rubber tube 701. A vibration damping disc 703 is fixedly connected to both ends of the vibration damping rod 702. The two vibration damping discs 703 are fixedly connected to both ends of the rubber tube 701. A spring 704 is fixedly connected between the two vibration damping discs 703 and the two ends of the threaded tube 6. Both springs 704 are sleeved on the outside of the rubber tube 701.

[0029] The rubber tube 701 is internally inlaid with a set of radially spaced, annularly arranged damping elements 8. Each radial damping element 8 is arranged along the length of the rubber tube 701, and the length of the radial damping element 8 is equal to the length of the threaded tube 6. The mounting bracket 17 is rotatably connected to its corresponding damping disc 703. The two ends of the rubber tube 701 extending out of the threaded tube 6 are corrugated. The corrugation is achieved by opening annular corrugated grooves on the inner wall and outer surface of the rubber tube 701. When subjected to axial vibration force, the damping disc 703 at one end of the damping rod 702 compresses the spring 704, and the damping disc 703 at the other end of the damping rod 702 compresses the spring 704. At the same time, the compression and stretching of the corrugated section of the rubber tube 701 produces a damping effect, effectively absorbing axial vibration energy. The inner wall of the rubber tube 701 has an annular cavity coaxial with the rubber tube 701. A set of radially spaced radial damping elements 8 are located in the annular cavity. The radial damping elements 8 include two arc-shaped fixing plates 801. One arc-shaped fixing plate 801 is fixedly connected to the inner wall of the outer ring forming the annular cavity, and the other arc-shaped fixing plate 801 is fixedly connected to the inner wall of the inner ring forming the annular cavity. Two C-shaped elastic plates 802 are arranged between the two arc-shaped fixing plates 801. The two C-shaped elastic plates 802 are symmetrically arranged, and their openings face away from each other. The two C-shaped elastic plates 802 are integrally formed from spring steel. When subjected to radial vibration force, they compress the rubber tube 701 to produce a damping effect, and at the same time, they cooperate with the C-shaped elastic plates 802 to undergo elastic deformation, further absorbing radial vibration energy.

[0030] A handle 14 is fixedly connected to the outer surface of both the threaded tube 6 and the lifting rod 3, facilitating the user to adjust the height of the voiceprint collector 18 from the ground and the distance between it and the equipment, thus improving the convenience of installation and adjustment. A first laser rangefinder 15 is installed vertically downward at one end of the mounting plate 4, and a second laser rangefinder 16 is installed horizontally along the radial direction of the fixed tube 2 on one side of the mounting bracket 17, facilitating the user to judge the height of the voiceprint collector 18 from the ground and the distance between it and the equipment, ensuring compliance with measurement specifications, and improving the accuracy and standardization of measurements. An adsorption rod 9 is slidably sleeved at the bottom end of the fixed tube 2 along its axis, and the bottom end of the adsorption rod 9 is fixed... A suction cup 10 is fixedly installed. Since the indoor floor of the pump station is flat and coated with epoxy resin paint, the suction cup 10 can be firmly attached to the ground, preventing the tripod 1 from tipping over and causing accidents. Two handles 11 are fixedly installed radially at the top of the suction rod 9. Two radially arranged screws 12 are threaded to the top of the suction rod 9. The handles 11 make it easy for the user to press down the suction cup 10 to fix the tripod 1. After fixing or unfixing, the suction rod 9 can be locked by turning the screws 12 to make tight contact with the fixing tube 2, preventing the suction cup 10 from sliding down when the tripod 1 is moved.

[0031] The working principle of the above embodiment is as follows: When the voiceprint sensor bracket is working, the tripod 1 is first placed in a suitable position in the pump station room. The handle 11 at the top of the suction rod 9 is used to press down the suction cup 10, so that the suction cup 10 is firmly attached to the flat ground coated with epoxy resin paint. Then, the screw 12 at the top of the suction rod 9 is rotated to make it tightly contact the fixing tube 2, thereby locking the suction rod 9 and preventing the suction cup 10 from slipping when the tripod 1 is moved, ensuring the stability of the bracket. By rotating the handle 14 on the outer surface of the threaded tube 6 and the lifting rod 3, the position of the threaded tube 6 in the threaded sleeve 5 can be adjusted, thereby adjusting the height of the voiceprint collector 18 from the ground and the distance between the device and the equipment. The vertically downward first laser rangefinder 15 at one end of the mounting plate 4 and the second laser rangefinder 16 horizontally arranged radially along the fixing tube 2 on one side of the mounting bracket 17 can help the user accurately determine the position of the voiceprint collector 18, ensuring the measurement is standardized. When the large pump group generates vibration during operation and transmits it to the bracket, the axial vibration is transmitted... The vibration damping rod 702 is delivered to the vibration damping assembly 7. The vibration damping disc 703 at one end of the vibration damping rod 702 compresses the spring 704 in contact with it, while the vibration damping disc 703 at the other end of the vibration damping rod 702 compresses the spring 704 in contact with it. At the same time, the rubber tube 701 extends out of the threaded tube 6 with corrugated ends. The corrugated sections are compressed and stretched to produce a damping effect, effectively absorbing axial vibration energy. For radial vibration, an arc-shaped fixing plate 801 is fixedly installed on the inner wall of the outer ring and the inner wall of the inner ring of the annular cavity of the rubber tube 701, respectively. Two symmetrically arranged, oppositely spaced C-shaped elastic plates 802, integrally formed from spring steel, are placed between the two arc-shaped fixing plates 801. The radial vibration force compresses the rubber tube 701 to produce a damping effect. At the same time, the C-shaped elastic plates 802 undergo elastic deformation, further absorbing radial vibration energy. Through dual vibration damping in both axial and radial directions, the impact of vibration on the acoustic fingerprint collector 18 is minimized, ensuring the measurement accuracy of the acoustic fingerprint collector 18 and providing reliable data for pump unit status monitoring.
