Description

Technical Field

[0001] The utility model belongs to the technical field of soil vibration testing, and particularly relates to a quick connection device for vibration sensors. Background Art

[0002] During the construction of industrial factory building projects with anti-microvibration requirements, soil vibration testing under natural site conditions is an important content. Generally, three single-axis vibration sensors are used to test the vibration of the soil. During the test, the vibration sensors are divided into two horizontal directions and one vertical direction, and the two vibration sensors in the horizontal direction are perpendicular to each other.

[0003] At present, the main method of soil vibration testing is to excavate a test pit and tamp the soil, and then place the vibration sensor on the soil surface to test the soil vibration. During the process of testing the soil vibration, it is necessary to tightly connect the vibration sensor to the soil and keep it horizontal to ensure the accuracy of the test results; when conducting vibration testing, the vibration sensor needs to be placed horizontally. The natural site surface is uneven, and it is difficult to ensure that the vibration sensor is placed horizontally. Moreover, generally three single-axis vibration sensors are used for soil vibration testing. Before the test, it is necessary to separately calibrate the horizontal level of the vibration sensors placed on the ground. The on-site operation is cumbersome and the construction efficiency is low. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick connection device for vibration sensors to solve the technical problem that it is difficult to horizontally place the vibration sensor in the soil during testing, and achieve the purpose of making the vibration sensor horizontal to improve the test accuracy.

[0005] To solve the above technical problem, the utility model provides a quick connection device for vibration sensors, including: a fixing plate and a plurality of vibration sensors, and the fixing plate is detachably connected to the plurality of vibration sensors;

[0006] The fixing plate is cylindrical, and four limiting grooves are opened at the top end of the fixing plate. The four limiting grooves are arranged at equal intervals, and all four limiting grooves penetrate through the side wall of the fixing plate;

[0007] The number of the plurality of vibration sensors is three. The vibration sensors are respectively placed in the limiting grooves, and counterweight blocks are placed in the remaining limiting grooves.

[0008] Further, the vibration sensor includes a mounting block and a connecting rod, and the top end of the mounting block is connected to the bottom end of the connecting rod.

[0009] Further, the mounting block is cube-shaped, the connecting rod is cylindrical, and the mounting block matches the limiting groove.

[0010] Further, a retaining piece is provided at one end of the limiting groove close to the side wall of the fixing plate.

[0011] Further, the mounting block is arranged in the limiting groove, and the limiting groove abuts against the retaining piece.

[0012] Further, the counterweight block is matched with the limiting groove, and the counterweight block abuts against the retaining piece.

[0013] Further, a leveling groove is formed in the middle of the top end of the fixing plate, and leveling liquid and a leveling bubble are arranged in the leveling groove.

[0014] Further, a spring is connected to the bottom end of the fixing plate.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By arranging a spring to rotate the vibration sensor connecting device into the soil body, the vibration sensor is tightly connected to the soil body and kept horizontal, thereby ensuring the accuracy of the test results.

[0017] 2. By arranging a leveling bubble on the fixing plate to keep the fixing plate in a horizontal state, when the vibration sensor is placed on the fixing plate, its horizontal state is maintained, which is convenient for sensor calibration.

[0018] 3. By arranging a limiting groove on the fixing plate and placing the vibration sensor in the limiting groove, the retaining piece ensures that there is no slippage between the vibration sensor and the fixing plate.

[0029] Embodiment:

[0030] As Figures 1 to 3 shown, a rapid connection device for vibration sensors includes: a fixed plate 1, a plurality of vibration sensors 3 and a counterweight 4. The fixed plate 1 is detachably connected to the plurality of vibration sensors 3. A leveling groove 11 is provided in the middle of the top end of the fixed plate 1. A leveling liquid and a leveling bubble are arranged in the leveling groove 11. A spring 2 is connected to the bottom end of the fixed plate 1. The device is rotated into the soil through the spring 2 to improve the connection stability between the vibration sensor 3 and the soil. When the vibration sensor 3 is tested, the leveling liquid and the leveling bubble adjust the inclination of the device to keep the device and the vibration sensor 3 horizontal.

[0031] The fixed plate 1 is cylindrical. Four limit grooves 12 are provided at the top end of the fixed plate 1. The four limit grooves 12 are arranged at equal intervals and all penetrate through the side wall of the fixed plate 1. A flap 13 is provided at one end of the limit groove 12 close to the side wall of the fixed plate 1.

[0032] As Figure 2 shown, the number of the plurality of vibration sensors 3 is three. The vibration sensors 3 are respectively placed in the limit grooves 12, and the counterweight 4 is placed in the remaining limit grooves 12. The counterweight 4 balances the vibration sensor 3 to keep it horizontal. The vibration sensor 3 includes a mounting block 31 and a connecting rod 32. The top end of the mounting block 31 is connected to the bottom end of the connecting rod 32. The mounting block 31 is cubic and the connecting rod 32 is cylindrical. The mounting block 31 matches the limit groove 12. The mounting block 31 is arranged in the limit groove 12, and the limit groove 12 abuts against the flap 13. As Figure 3 shown, the counterweight 4 matches the limit groove 12, and the counterweight 4 abuts against the flap 13. The vibration sensor 3 and the counterweight 4 are placed in the limit groove 12 through the flap 13 to prevent them from slipping.

[0033] To summarize, the spring 2 is rotated into the soil to generate friction resistance between the spring 2 and the soil, thereby ensuring a tight connection between the device and the soil. The vibration sensor 3 and the counterweight 4 are installed in the limit groove 12. The leveling fluid and leveling bubbles ensure that the vibration sensor 3 remains horizontal. The vibration sensor 3 is easy to install and disassemble. The spring 2 effectively transmits the soil vibration to the fixed plate 1, and then transmits it to the vibration sensor 3 through the fixed plate 1 to complete the test.
