Detailed Implementation

[0033] 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.

[0034] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a seismic wave reflection survey probe bracket, comprising a tripod 1. Three extension rods 2 are rotatably connected to the top of the tripod 1 to extend the length of the support frame, making it more adaptable to different application environments. A rotating rod 3 is slidably connected to the outside of each extension rod 2, allowing the extension rod 2 to slide along the inner wall of the rotating rod 3 to adjust the length of the support frame. A fixing ring 4 is fixedly connected to the outside of the rotating rod 3, protecting the internal locking structure. A groove is formed on the inner wall of the fixing ring 4, and a rotating handle 5 is rotatably connected to the inner wall of the groove. Turning the rotating handle 5 allows it to rotate by a certain angle.

[0035] The extension rod 2 has a locking groove 7 on its outer side, and a locking block 6 is slidably connected to the outer side of the locking groove 7. The locking block 6 is close to the locking groove 7, which fixes the position between the extension rod 2 and the rotating rod 3; conversely, it allows the extension rod 2 to move freely. The outer side of the rotating handle 5 is in contact with the outer side of the locking block 6 (as shown in the attached figure). Figure 4 The rotation of the rotating handle 5 can push the locking block 6 to move. The other ends of the three rotating rods 3 are rotatably connected to the water platform 20. The position change of the rotating rods 3 causes the position change of the water platform 20. The top of the water platform 20 is equipped with a surveyor 8. The position change of the water platform 20 causes the position of the surveyor 8 to change.

[0036] Reference Figure 3 and Figure 6 The base of the tripod 1 is fixedly connected to a stabilizing component to adapt the device to various terrains. The stabilizing component includes a base 14, the inner wall of which is fixedly connected to a horizontal bar 19. The horizontal bar 19 maintains stability and can stabilize the swaying structure. Four movable columns 13 are fixedly connected to the base of the tripod 1; any movement of the tripod 1 will cause the four movable columns 13 to sway. Movable balls 15 are movably connected to the bottom of each movable column 13; any movement of the movable columns 13 will cause the movable balls 15 to sway. The inner wall of the movable ball 15 is movably connected to the inner wall of the base 14, and the base 14 serves to fix the movable ball 15 in its position.

[0037] Spring 16 is fixedly connected to the inner wall of the movable ball 15 (as shown in the attached image). Figure 6The movement of the movable ball 15 causes the second spring 16 to deform, and the return of the second spring 16 counteracts most of the shaking force. The other end of the second spring 16 is fixedly connected to the inner wall of the base 14, and the base 14 has a fixed position function for the second spring 16. The two movable columns 13 are slidably connected to the outside of the sliding rods 17, which are used to keep the relative position of the two movable columns 13 stable. The movable columns 13 are movably connected to the inside of the base 14, and the base 14 has a partial position stabilizing effect on the movable columns 13 when they shake. The inner wall of the sliding rods 17 has movable grooves 18, and the outside of the horizontal rod 19 is movably connected to the inner wall of the two movable grooves 18. The position stabilization of the horizontal rod 19 drives the stabilization of the two movable grooves 18, which in turn drives the relative position stabilization of the two sliding rods 17.

[0038] Reference Figure 2 and Figure 5 The inner wall of the tripod 1 is threaded with three bolts 9, which are used to fix the tripod 1 to the ground when the surveyor 8 is positioned. Three fixed posts 10 are fixedly connected to the bottom of the tripod 1. A sliding post 11 is slidably connected to the inner wall of each fixed post 10, and the fixed posts 10 are used to slide and fix the sliding post 11 in position. A spring 12 is fixedly connected to the inner wall of each fixed post 10, and the fixed posts 10 fix the spring 12 in position, allowing the spring 12 to return to its original position smoothly. The other end of the spring 12 is fixedly connected to the inner wall of the sliding post 11 (as shown in the attached figure). Figure 5 When the sliding column 11 touches the ground, the movement of the sliding column 11 causes the spring 12 to deform. The inner wall of the sliding column 11 is slidably connected to the outside of the bolt 9, so that the movement of the bolt 9 will not cover the movement of the sliding column 11.

[0039] Working principle: Turning the rotating handle 5 releases the pressure on the locking block 6, thereby changing the relative position between the extension rod 2 and the rotating rod 3, thus changing the length of the support frame. Then, turning the rotating handle 5 in the opposite direction presses the locking block 6, causing the locking block 6 to press against the locking groove 7, thereby locking the position between the extension rod 2 and the rotating rod 3. The support height and range can be flexibly changed according to different terrains, geological conditions and survey requirements. Whether in rugged mountains or flat plains, it can ensure that the probe is in the optimal measurement position, improving adaptability to various environments.

[0040] Rotating the three bolts 9 causes the tripod 1 to move closer to the ground, releasing the sliding column 11 from the ground. The reverse motion of the sliding column 11 causes the spring 12 to deform, and the return of the spring 12 moves the sliding column 11 closer to the ground, making the fixation of the bracket more stable and ensuring that the probe is in a stable measurement position. The wobbling of the tripod 1 causes multiple movable columns 13 to wobble, which in turn causes the movable ball 15 to wobble. The wobbling of the movable ball 15 causes the spring 16 to deform, and the return of the spring 16 cancels out most of the wobbling force. The horizontal rod 19 horizontalizes the two sliding rods 17, and the horizontalization of the two sliding rods 17 horizontalizes the four movable columns 13, thereby reducing measurement errors caused by environmental factors, improving the accuracy of survey data, enhancing the ability to adapt to uneven road surfaces, increasing the stability of the equipment, and reducing the risk of damage to the equipment during transportation and use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
