Description

Technical Field

[0001] The utility model relates to the technical field of wave speed testing, in particular to a wave speed testing device. Background Art

[0002] Wave velocity test refers to the sonic test on soil. The test data can be used to analyze the soil and make settings in advance.

[0003] In wave velocity testing, an acoustic wave meter is usually required. An acoustic source signal generator generates electrical pulses of a certain frequency, which are amplified and converted into sound waves by a transmitting transducer and radiated to the rock mass. The receiver is connected to a microcomputer to process the sound wave signal.

[0004] When measuring soil waves, a hole is drilled in the ground and a wave measuring probe is placed in the hole so that the wave measuring probe is in the soil and then lowered to a suitable position to generate electric pulses of a certain frequency. In the prior art, the wave measuring probe is directly below the soil. During the process, the outside of the wave measuring probe is unprotected. After multiple collisions, the wave measuring probe will be damaged, resulting in failure to perform normal testing. At the same time, the position of the wave measuring probe is unstable and prone to shaking, which affects the test data. Therefore, we propose a wave velocity testing device. Utility Model Content

[0026] The protection unit includes a protection seat 6 and a sliding rod 601. The protection seat 6 is fixedly connected to the sliding rod 601. The sliding rod 601 is slidably connected to the inner wall of the connecting rod 501. The protection unit moves by adjusting the protection seat 6. The movement of the connecting rod 501 causes the sliding rod 601 and the protection seat 6 to move. Under the rebound of the spring 602, the protection seat 6 is pushed to contact the soil. Under the action of the protection seat 6, the position of the test probe 3 is limited. At the same time, under the action of the protection seat 6, the test probe 3 is protected to avoid collision and damage to the test probe 3, so that the test probe 3 can be tested normally. During the test, the position of the test probe 3 is stable to ensure the accuracy of the test data.

[0027] The outer wall of the test probe 3 is threadedly connected to a handle 4, and the bottom end surface of the handle 4 is rotatably connected to a movable seat 401. By rotating the handle 4, the handle 4 slides along the threaded sleeve 301, and the movement of the handle 4 drives the movable seat 401 to move.

[0028] The bottom end surface of the movable seat 401 is rotatably connected to the first rotating rod 5 .

[0029] The first rotating rod 5 is rotatably connected to the corresponding connecting rod 501. When the movable seat 401 moves and pushes the corresponding first rotating rod 5 to rotate, the connecting rod 501 moves under the rotation of the first rotating rod 5, and then the connecting rod 501 and the connecting seat 502 move at the same time.

[0033] When the protective seat 6 is in contact with the soil, the protective seat 6 and the soil cannot move. When the connecting rod 501 continues to move, the spring 602 is compressed. Under the rebound of the spring 602, the position of the protective seat 6 is limited. Under the action of the protective seat 6, the test probe 3 is protected and the position of the test probe 3 is limited to avoid collision and damage of the test probe 3, so that the test probe 3 can be tested normally. The position of the test probe 3 is stable during the test to ensure the accuracy of the test data.

[0035] By rotating the handle 4, the handle 4 slides along the threaded sleeve 301, and the handle 4 drives the moving seat 401 to move.

[0036] When the moving seat 401 moves and pushes the corresponding first rotating rod 5 to rotate, the connecting rod 501 moves under the rotation of the first rotating rod 5, and then the connecting rod 501 and the connecting seat 502 move at the same time;

[0037] When the connecting rod 501 and the connecting seat 502 move, the spring 602 is driven to move, and the spring 602 pushes the protective seat 6 to move;

[0038] When the protective seat 6 is in contact with the soil, the protective seat 6 and the soil cannot move. When the connecting rod 501 continues to move, the spring 602 is compressed. Under the rebound of the spring 602, the position of the protective seat 6 is limited. Under the action of the protective seat 6, the test probe 3 is protected and the position of the test probe 3 is limited to avoid collision and damage of the test probe 3, so that the test probe 3 can be tested normally.
