Description

TECHNICAL FIELD

[0001] The application relates to the technical field of horizontal force monitoring of energy dissipation shock absorbers, in particular to a horizontal force monitoring device for energy dissipation shock absorbers. BACKGROUND

[0002] With the release of the new version of the seismic zoning map in China, the seismic fortification intensity of a large number of regions has been significantly improved. Especially in high-intensity fortification regions and earthquake key monitoring and prevention zones, the traditional "hard resistance" seismic method has been difficult to meet the safety needs of buildings. In order to meet this challenge, the State has promulgated the "Regulations on the Seismic Management of Construction Projects", which clearly stipulates that important public facilities such as schools and hospitals should adopt seismic isolation and mitigation technology. Energy dissipation shock absorbers, as an effective seismic measure, are widely used in these buildings, which can absorb and dissipate energy when earthquakes occur, thereby reducing the damage risk of buildings by being installed between the upper and lower walls.

[0003] However, in practical applications, the existing energy dissipation shock absorbers mainly focus on reducing the instantaneous damage of earthquakes to buildings, and lack effective monitoring means for the health status of buildings after earthquakes. For example, the Chinese invention patent with the publication number CN118032185A discloses a device for measuring the horizontal tension of a product, which comprises a force gauge, a support assembly, a pulley assembly and a traction rope. The traction rope includes a first traction rope, one end of which is fixed to the force gauge, the other end of which passes through a fixed pulley and is fixed to the product. The force gauge can drive the first traction rope to move, thereby realizing the measurement of the horizontal tension of the product.

[0004] The above-mentioned device has a simple structure and is easy to operate, but it is mainly used for static or low-frequency horizontal force measurement. Once applied to energy dissipation shock absorbers, it cannot effectively adapt to the high-frequency and high-intensity horizontal force changes caused by seismic transverse waves, resulting in obvious deficiencies in the health status monitoring of energy dissipation shock absorbers after earthquakes, especially the inability to accurately monitor the horizontal force of the wall in real time, which increases the difficulty of post-earthquake evaluation and repair work and affects the long-term safety and reliability of the building. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the safety detection of buildings, the application provides a horizontal force monitoring device for energy dissipation shock absorbers.

[0006] The horizontal force monitoring device for energy dissipation shock absorbers provided by the application adopts the following technical scheme:

[0007] The utility model provides an energy dissipation shock absorber horizontal force monitoring device, including fixed casing, be equipped with guide chute and rolling ball in fixed casing, the guide chute is arranged in the inner bottom of fixed casing parallel to the length direction of fixed casing, the rolling ball can roll along the guide chute, signal sending module is installed on the rolling ball, a plurality of signal receiving modules are installed along the length direction of fixed casing in fixed casing, when the rolling ball rolls on the guide chute, corresponding signal receiving module receives the signal that signal sending module sent, and real -time position information is transmitted to external processing system.

[0008] Through the above technical scheme, when the energy dissipation shock absorber is subjected to horizontal force in the earthquake process, the rolling ball will roll along the guide chute, and the signal sending module will move and continuously send signals to the signal receiving module. These signal receiving modules can capture the position change of the rolling ball in real time and transmit the data to the external processing system, thereby realizing dynamic monitoring of the horizontal force of the energy dissipation shock absorber. This design not only improves the monitoring accuracy, but also ensures the continuity and reliability of data acquisition, which helps to discover potential safety hazards in time and improve the seismic performance and safety of buildings.

At the same time, the rotatable connection between the driving rod and the rolling ball ensures the flexibility of the rolling ball, reduces the friction resistance, improves the response speed and accuracy. In addition, the two stretchers are symmetrically arranged on the two sides of the driving rod, which ensures that the rolling ball can remain stable when subjected to force in different directions, avoids the deviation or jamming phenomenon caused by unilateral force, and improves the reliability and accuracy of the whole device.

Meanwhile, these fixing holes also facilitate later maintenance and replacement, ensuring the stability and reliability of the monitoring device.

[0017] Optionally, the top cover is made of transparent material.

[0018] By adopting the technical scheme, the top cover is made of transparent material, so that the internal rolling ball and its movement trajectory can be directly observed, facilitating timely discovery and adjustment of problems during testing, improving the operation convenience and maintainability of the device. Meanwhile, the transparent top cover also enables external light to enter, avoiding poor visibility caused by obstruction, and further improving the use experience of the device.

[0019] Optionally, a scale is arranged on one side of the guide sliding groove, and scale marks are arranged on the scale, each signal receiving module being arranged in correspondence with a corresponding scale mark.

[0034] Referring to Figure 1When the energy dissipation damper is subjected to horizontal force during the earthquake, the rolling ball 3 will roll along the guide chute 2, the signal sending module 6 on the rolling ball 3 will move and continuously send signals to the signal receiving module 7 connected to it, the corresponding signal receiving module 7 receives the signal sent by the signal sending module 6, and transmits the real-time position information to the external processing system, thereby realizing dynamic monitoring of the horizontal force of the energy dissipation damper. The displacement of the rolling ball 3 can also be directly observed by the scale mark 51 on the scale 5, and the rolling ball 3 can be quickly reset under the action of the stretching piece 4.

[0035] Referring to Figure 1 , the fixed shell 1 includes a base plate 11, a frame 12 and a top cover 13. The base plate 11 is made of thick steel plate or cast iron to provide a stable support base. The frame 12 is made of light and strong material such as aluminum alloy or carbon fiber to reduce the overall weight and is fixedly arranged on the top of the base plate 11. The top cover 13 is made of transparent material such as acrylic or glass to facilitate observation of the working state of the internal components. The top cover 13 is opened or closed by a locking part, which can be a bolt, a buckle or other quick release clamp.
