Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for high-precision sensors, specifically a vibration damping bracket for mounting high-precision sensors. Background Technology

[0002] Currently, the construction of large-scale pumping stations is showing a trend of "expanded scale, integrated equipment, and multifunctionality." The number of embedded parts can reach hundreds to thousands, covering dozens of types such as bolt groups, lifting rings, pipe interfaces, and electrical grounding terminals. A full-discipline BIM collaborative model covering civil structure, embedded parts, and electromechanical equipment is established. The Revit+Navisworks platform is used to realize parametric modeling of components. Information such as the material, specifications, coordinates, embedment depth, and anchoring method of embedded parts are included in the model attribute library. A wireless sensor monitoring system is deployed, and strain sensors and displacement sensors are installed at the equipment base and embedded part connection to monitor stress changes and displacement in real time during equipment installation. Due to the risk of data distortion in wireless sensor monitoring, which manifests as the sensor being affected by construction vibration and electromagnetic interference, the data collection is inaccurate. Therefore, a vibration damping bracket is needed to overcome the problem of sensor distortion caused by construction vibration. In the prior art, patent publication number CN213900634U discloses a shock-absorbing device for sensors, including a mounting plate. Two fixing holes are formed on each of the two outer walls of the top of the mounting plate. A support base is fixed to the top outer wall of the mounting plate by bolts. First sliding grooves are formed on both inner walls of the support base. The inner walls of the two first sliding grooves are slidably connected to the same support plate. A fixing base is fixed to the top outer wall of the support plate by bolts. Rubber pads are fixedly connected to both outer walls of the fixing base. An opening is formed on the top outer wall of the support base, and two rubber pads are slidably connected to the inner walls on both sides of the opening. A sensor body is fixedly connected to the top outer wall of the fixing base. The above-mentioned vibration damping device has some problems in actual use. For example, the vertical vibration damping is achieved by using elastic metal plates, multiple sets of compression springs and linkage structure, which is complex and the spring force is unstable, resulting in limited vibration damping capacity. Therefore, we propose a vibration damping bracket for high-precision sensor installation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing bracket for mounting high-precision sensors, including a lower connecting seat and a vertical shock-absorbing mechanism; Vertical vibration damping mechanism: It includes a fixed sleeve, a sliding hole, a sliding column, a spiral groove, a bearing, a rotating column, and a spiral block. The fixed sleeve is located on the upper side of the lower connecting seat. A sliding hole is opened on the upper side of the fixed sleeve. A sliding column is slidably connected inside the sliding hole. The upper end of the sliding column is fixedly connected to the upper connecting seat.

A spiral block is fixedly connected to the lower side of the outer arc surface of the rotating column. A spiral groove is opened on the lower side of the inner arc surface of the fixed sleeve. The outer surface of the spiral block is slidably connected to the inside of the spiral groove, effectively eliminating vibration force. The structure is simple.

[0005] Furthermore, the vertical damping mechanism also includes guide grooves and guide strips. The guide strips are uniformly fixedly connected to the outer arc surface of the sliding column, and the inner arc surface of the sliding hole is provided with uniformly distributed guide grooves. The outer surfaces of the three guide strips are respectively slidably connected to the inside of the guide grooves located on the same side, so as to realize the function of the sliding column moving vertically up and down.

[0006] Furthermore, it also includes a rubber damping ring, which is fixedly sleeved on the lower side of the outer arc surface of the fixed sleeve.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a high-precision sensor mounting shock-absorbing bracket, including a lower connecting seat 1 and a vertical shock-absorbing mechanism 2; Vertical damping mechanism 2: It includes a fixed sleeve 21, a sliding hole 22, a sliding column 23, a spiral groove 26, a bearing 27, a rotating column 28, and a spiral block 29. The fixed sleeve 21 is located on the upper side of the lower connecting seat 1. The upper side of the fixed sleeve 21 has a sliding hole 22. The sliding column 23 is slidably connected inside the sliding hole 22. The upper end of the sliding column 23 is fixedly connected to the upper connecting seat 6. The lower surface of the sliding column 23 is rotatably connected to the rotating column 28 through the bearing 27. The lower side of the outer arc surface of the rotating column 28 is fixedly connected to the spiral block 29. The lower side of the inner arc surface of the fixed sleeve 21 has a spiral groove 26. The outer surface of the spiral block 29 is slidably connected to the interior of the spiral groove 26 (the inner surface of the spiral groove 26 and the outer surface of the spiral block 29 are coated with YT-Z1 damping). The coating increases friction, and the heat generated after friction will dissipate along the inner wall of the fixed sleeve 21. The vertical damping mechanism 2 also includes guide grooves 24 and guide strips 25. The guide strips 25 are uniformly fixedly connected to the outer arc surface of the sliding column 23. The inner arc surface of the sliding hole 22 is provided with uniformly distributed guide grooves 24. The outer surfaces of the three guide strips 25 are respectively slidably connected to the inside of the guide grooves 24 located on the same side. It also includes a rubber damping ring 8, which is fixedly sleeved on the lower side of the outer arc surface of the fixed sleeve 21. The outer arc surface of the rubber damping ring 8 is fixedly connected to the inner arc surface of the lower connecting seat 1 (the lower surface of the rubber damping ring 8 is not fixedly connected to the upper side wall of the lower connecting seat 1). A circular top block 4 is fixedly connected to the lower end of the rotating column 28. A top post 3 is provided on the lower side of the inner arc surface of the fixed sleeve 21. A circular top groove 5 is opened on the upper surface of the top post 3. The outer surface of the circular top block 4 is in contact with the inside of the circular top groove 5. A spring 7 is fixedly connected to the upper surface of the top post 3. The lower end of the spring 7 is fixedly connected to the upper side of the lower connecting seat 1. A disassembly plate 9 is fixedly connected to the middle of the lower surface of the lower connecting seat 1 by screws (after long-term use, the lower connecting seat 1 can be disassembled by removing the disassembly plate 9 to replace or maintain the internal spring). The edges of the lower connecting seat 1 and the upper connecting seat 6 are respectively provided with evenly distributed screw holes. When deploying a wireless sensing monitoring system, strain sensors and displacement sensors are usually installed at the connection between the equipment base and the embedded parts. The device may experience vibrations due to the working environment, causing the sensor on the embedded part to vibrate slightly when the equipment base vibrates, leading to inaccurate data acquisition. In this case, the equipment base can be fixedly connected to the lower connecting seat 1 of this vibration damping bracket, and then the sensor can be installed on the upper connecting seat 6. The position of the sensor and the embedded part can be fixed (if the amplitude is small, the rubber damping ring 8 can absorb some of the small vibration force; the following vibration damping method is performed when the amplitude exceeds one-quarter of the height of the rubber damping ring 8). At this time, whenever the equipment base vibrates, it causes the fixed sleeve 21 to vibrate up and down. This vibration force causes the fixed sleeve 21 to move up and down slightly. Whenever the fixed sleeve 21 moves upward...The spiral groove 26 and the spiral block 29 maintain a sliding connection, driving the rotating column 28 to rotate counterclockwise. At this time, the friction area between the inner surface of the spiral groove 26 and the outer surface of the spiral block 29 is large. Both the inner surface of the spiral groove 26 and the outer surface of the spiral block 29 are coated with damping paint. Heat is generated during friction, and this heat is transmitted through the cylinder of the fixed sleeve 21, achieving vertical vibration reduction. During this vibration, the spring 7 is compressed to store energy. During the intervals of vibration, it pushes the top column 3 upward, forcing the rotating column 28 to rotate clockwise and reset. As the vibration force continues to be transmitted to the lower connecting seat 1, the above steps are repeated to achieve continuous vertical vibration reduction. In special conditions where external forces other than vertical vibration occur, the rubber damping ring 8 tightly grips the lower side of the outer arc surface of the fixed sleeve 21, relying on the deformation and recovery characteristics of the rubber damping ring 8 itself to offset this external force, achieving multi-angle vibration reduction.

[0016] The working principle of the high-precision sensor mounting shock-absorbing bracket provided by this utility model is as follows: When deploying a wireless sensor monitoring system, strain sensors and displacement sensors are usually installed at the connection between the equipment base and the embedded part. Due to vibrations in the working environment, the sensors on the embedded part may also vibrate slightly when the equipment base vibrates, leading to inaccurate data acquisition. In this case, the equipment base can be fixedly connected to the lower connecting seat 1 of this shock-absorbing bracket, and then the sensor can be installed on the upper connecting seat 6, fixing the position of the sensor and the embedded part. When the equipment base vibrates, it causes the fixing sleeve 21 to vibrate up and down. This vibration force causes the fixing sleeve 21 to move up and down slightly. Whenever the fixing sleeve 21 moves upward, the spiral groove 26 and the spiral block 29 maintain their positions. The sliding connection causes the rotating column 28 to rotate counterclockwise. At this time, the friction area between the inner surface of the spiral groove 26 and the outer surface of the spiral block 29 is large. Both the inner surface of the spiral groove 26 and the outer surface of the spiral block 29 are coated with damping paint. Heat is generated during the friction process. The heat is transmitted out with the cylinder of the fixed sleeve 21, realizing the function of vertical vibration reduction. During the vibration, the spring 7 is compressed to store energy. During the interval of vibration, the top column 3 is pushed upward, forcing the rotating column 28 to rotate clockwise to reset. When the vibration force is continuously transmitted to the lower connecting seat 1, the above steps are repeated to realize the function of continuous vertical vibration reduction. In special conditions, when external forces other than vertical vibration occur, the rubber damping ring 8 inside the rubber damping ring 8 tightly grips the lower side of the outer arc surface of the fixed sleeve 21. The deformation and recovery characteristics of the rubber damping ring 8 itself are used to offset this part of the external force to realize the function of multi-angle vibration reduction.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
