[0003] However, when the device is performing vertical well inclination measurement, sometimes it collides with the inner wall or bottom of the vertical well due to falling too fast, causing the device to vibrate, thereby causing damage to the internal parts of the device and making the device unable to perform normal detection. For this reason, we provide a high-temperature vertical well inclinometer. Utility Model Content

[0008] Furthermore, a limiting rod is fixedly connected to the top of the base plate, the outer surface of the limiting rod is slidably connected to the inner wall of the main body, the end of the extrusion spring away from the moving block is fixedly connected to the inner wall of the movable groove, and the top and bottom of the connecting rod are fixedly connected to the reinforcing rod. There are four reinforcing rods in total, and the four reinforcing rods are symmetrically arranged with the connecting rod as the center. The inner wall of the main body is fixedly connected to a support frame, and the support frame is used to limit the extrusion rod to prevent it from deflecting.

[0009] Furthermore, a slider is fixedly connected to the inner wall of the support frame, a slide groove is provided inside the extrusion rod, the inner wall of the slide groove is slidably connected to the outer surface of the slider, and the extrusion is limited by the cooperation of the slide groove and the slider to prevent it from rotating during movement.

When the connecting block 1 moves upward, it will also drive the connecting rod to move and make its other end move outward. When the connecting rod is pushed outward, it drives the connecting block 2 to move, and then the movement of the connecting block 2 drives the buffer cover to move, so that the buffer cover extends out of the main body to release the impact, and when the buffer cover moves, it will drive the moving block to move and squeeze the extrusion spring, and then the reaction force generated by the squeezing of the squeezing spring will further weaken the impact force to prevent damage to the internal device.

[0014] 2. The utility model sets a mounting plate, which is placed at the center of the sliding groove, so that the clamping block enters the sliding groove, and then slides the mounting plate to slide outward along the sliding groove. When the mounting plate moves, the clamping block is driven to move. When the clamping block slides to the deepest point, the clamping block will first squeeze the protrusion to make it enter the squeezing groove, and at the same time squeeze the spring. When the groove inside the clamping block is aligned with the protrusion, the spring rebounds and pushes the protrusion outward to make it enter the groove in the clamping block, thereby completing the positioning of the clamping block. The operation is simple, and if the internal module is damaged, it can be quickly replaced.

The mounting plate 205 is placed in the center of the sliding groove 206 so that the clamping block 208 enters the sliding groove 206. Then, the mounting plate 205 is slid and slides outward along the sliding groove 206. When the mounting plate 205 moves, the clamping block 208 is driven to move. When the connecting block 208 slides to the deepest part, the clamping block 208 will first squeeze the protrusion 207 to make it enter the extrusion groove 209, and at the same time squeeze the spring 1 211. When the groove 210 inside the clamping block 208 is aligned with the protrusion 207, the spring 1 211 rebounds and pushes the protrusion 207 outward to make it enter the groove 210 in the clamping block 208, completing the positioning of the clamping block 208.

When the mounting plate 205 moves, the clamping block 208 is driven to move. When the clamping block 208 slides to the deepest point, the clamping block 208 will first squeeze the protrusion 207 to make it enter the squeezing groove 206. 09, and at the same time squeeze the spring 1 211, and when the groove 210 inside the clamping block 208 is aligned with the protrusion 207, the spring 1 211 rebounds and pushes the protrusion 207 outward, so that it enters the groove 210 in the clamping block 208, completing the positioning of the clamping block 208. The operation is simple, and if the internal module is damaged, it can be quickly replaced. Then, align the clamping rod 202 on the outside of the cap 201 with the clamping groove 203 and press it downward, and then rotate it to complete the connection between the cap 201 and the main body 101. Then, the device is put into the vertical well. During the downward movement of the device or when it reaches the bottom, it may generate an impact force due to excessive speed, causing damage to the internal device of the main body 101. When the device moves downward, the bottom plate 102 will be hit first. When the bottom plate 102 is hit, it will push the extrusion rod 104 to move upward and drive the connecting block 107 to move. When the connecting block 107 moves upward, it will also drive the connecting rod 108 to move. Since the length of the connecting rod 108 is fixed, When one end of 08 moves upward, the other end will be pushed outward. When the connecting rod 108 is pushed outward, it drives the connecting block 2 110 to move, and then the movement of the connecting block 2 110 drives the buffer cover 111 to move, so that the buffer cover 111 extends out of the main body 101, releasing the impact, and when the buffer cover 111 moves, it drives the moving block 113 to move and squeeze the extrusion spring 112, and then the reaction force generated by the extrusion of the extrusion spring 112 is further weakened to prevent damage to the internal device.
