DETAILED DESCRIPTION
[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0023] like Figure 1 to Figure 5As shown, a seismic measuring instrument comprises a shell 1, and a partition 2 is fixedly connected to the top of the shell 1. The four corners of the bottom end of the shell 1 are fixedly connected to mounting plates 15, and the top of the mounting plates 15 is provided with mounting holes 16. The design of the mounting plates 15 and the mounting holes 16 allows the measuring instrument to be fixed by bolts. The bottom end of the partition 2 is fixedly connected to a fixing seat 3, and the bottom end of the fixing seat 3 is rotatably connected to a universal ball 4, and the bottom end of the universal ball 4 is fixedly connected to a connecting rod 5, and the bottom end of the connecting rod 5 is fixedly connected to a horizontal plate 6, and the top of the horizontal plate 6 is respectively fixedly connected to an X-axis velocity sensor 7, a Y-axis velocity sensor 8, and a Z-axis velocity sensor 9, and the X-axis velocity sensor 7, the Y-axis velocity sensor 8, and the Z-axis velocity sensor 9 are respectively arranged in three quadrants of the top of the horizontal plate 6, and the top of the horizontal plate 6 is fixedly connected to an acceleration sensor 10, and the top of the partition 2 is respectively fixedly connected to a data acquisition management module 11 and a transmission module 12.
[0024] During operation, the design of the universal ball 4 enables the horizontal plate 6 to always be in a horizontal state. When an earthquake occurs, the horizontal plate 6 can swing at will, and the horizontal plate 6 drives the connecting rod 5 to swing, and the connecting rod 5 drives the universal ball 4 to rotate in the fixed seat 3. In the process of the displacement of the horizontal plate 6, the X-axis velocity sensor 7, the Y-axis velocity sensor 8 and the Z-axis velocity sensor 9 will monitor and record the earthquake velocity, and the acceleration sensor 10 can monitor the change of the earthquake velocity in real time. Then the data acquisition management module 11 collects the sensed data in real time, and processes it into a data signal, and sends it to the external terminal using the transmission module 12. Then, the structure realizes that the horizontal plate 6 is always in a horizontal state through the universal ball 4, which provides convenience for observation, and the earthquake velocity is monitored and recorded by setting the X-axis velocity sensor 7, the Y-axis velocity sensor 8 and the Z-axis velocity sensor 9.
[0025] The four corners of the bottom end of the shell 1 are fixedly connected with spikes 13, and the spikes 13 are all conical. The design of the spikes 13 makes the measuring instrument applicable to mud and the seabed, etc., thereby improving the application range of the measuring instrument. A stabilizing mechanism 14 is provided at the bottom of the shell 1, and the stabilizing mechanism 14 includes through holes 140 opened at the bottom ends of the front and rear sides of the shell 1, springs 141 are fixedly connected to the inner sides of the through holes 140, and trapezoidal sliders 142 are fixedly connected to the ends of the springs 141, and inner cavities 143 are opened inside the thorns 13, and a group of sliding holes 144 are opened on both sides of the inner cavities 143, and movable rods 145 are provided in the inner cavities 143, and the top ends of the movable rods 145 extend into the through holes 140, and springs 146 are fixedly connected to the bottom ends of the springs 146, and the bottom ends of the springs 146 are fixedly connected to the bottom ends of the inner cavities 143, and hinged rods 147 are hinged on both sides of the movable rods 145, and plug rods 148 are slidably connected in the sliding holes 144, and the other ends of the plug rods 148 are hinged to the ends of the hinged rods 147. The top of the movable rod 145 is in an arc shape, and the end of the plug rod 148 away from the movable rod 145 is pointed. The arc-shaped design of the top of the movable rod 145 is conducive to reducing the friction between the movable rod 145 and the trapezoidal slider 142, and the pointed plug rod 148 is easy to be inserted deeply into the soil. The top of the outer side of the trapezoidal slider 142 is fixed with a fixing block 149, and the surface of the fixing block 149 is provided with a fixing hole 1490, and the bottom of the front and rear sides of the shell 1 is provided with a mounting groove 1491. The bottom of the trapezoidal slider 142 away from the through hole 140 is fixed with a cover block 17, and the cover block 17 is interference fit with the through hole 140. The cover block 17 is inserted into the through hole 140 by force, and can cooperate with the trapezoidal slider 142 to seal the through hole 140 to prevent seawater from entering the through hole 140. The bottom end of the movable rod 145 is provided with a limiting groove 18, the bottom end of the inner cavity 143 is fixedly connected to the limiting rod 19, and the top end of the limiting rod 19 extends to the limiting groove 18. The design of the limiting groove 18 and the limiting rod 19 limits the movement of the movable rod 145, so that it can only move vertically without being skewed.
[0026] During operation, after the thorn 13 is inserted into the soil or the seabed, the trapezoidal slider 142 is pressed, and the inclined surface at the bottom end of the trapezoidal slider 142 will squeeze the movable rod 145, and the movable rod 145 will move downward. In the process of moving downward, the movable rod 145 will drive the hinged rod 147 to rotate, and the hinged rod 147 drives the insertion rod 148 to slide to the outside of the sliding hole 144. The insertion rod 148 is gradually inserted horizontally into the soil or the seabed, and then the fixing block 149 and the mounting groove 1491 are fixed with bolts. At this time, the design of the insertion rod 148 is conducive to improving the stability of the shell 1 after it is fixed.
[0027] Working principle: After the thorn 13 is inserted into the soil or the seabed, the trapezoidal slider 142 is pressed, and the inclined surface at the bottom end of the trapezoidal slider 142 will squeeze the movable rod 145, and the movable rod 145 will move downward. During the downward movement of the movable rod 145, the hinged rod 147 will drive the insertion rod 148 to slide to the outside of the sliding hole 144, and the insertion rod 148 will gradually be inserted horizontally into the soil or the seabed, and then the fixing block 149 and the mounting groove 1491 will be fixed with bolts. At this time, the design of the insertion rod 148 is conducive to improving the stability of the shell 1 after it is fixed.
[0028] The design of the universal ball 4 enables the horizontal plate 6 to always be in a horizontal state. When an earthquake occurs, the horizontal plate 6 can swing at will, and the horizontal plate 6 drives the connecting rod 5 to swing, and the connecting rod 5 drives the universal ball 4 to rotate in the fixed seat 3. In the process of the displacement of the horizontal plate 6, the X-axis velocity sensor 7, the Y-axis velocity sensor 8 and the Z-axis velocity sensor 9 will monitor and record the earthquake velocity, and the acceleration sensor 10 can monitor the change of the earthquake velocity in real time. Then the data acquisition management module 11 collects the sensed data in real time, processes it into a data signal, and sends it to the external terminal using the transmission module 12. Then, the structure realizes that the horizontal plate 6 is always in a horizontal state through the universal ball 4, which provides convenience for observation, and the earthquake velocity is monitored and recorded by setting the X-axis velocity sensor 7, the Y-axis velocity sensor 8 and the Z-axis velocity sensor 9.
