[0002] GNSS, as one of the most advanced positioning methods today, has been widely used in water conservancy and hydropower projects such as earth-rock dams, arch dams, dikes, slopes, and land disaster management monitoring. Compared with conventional surveying methods, GNSS technology has significant characteristics and advantages. It is less affected by weather, points can be mutually independent, the three-dimensional coordinates of points can be acquired simultaneously, it is easy to carry out precise positioning over long distances, there is a wide range of choices for working base points, it can realize dynamic monitoring, and it has good automation and integration performance. It is particularly suitable for dynamic and static safety monitoring and complex measurement work that meets the needs of modern construction in large engineering areas. Its superior working performance and wide adaptability are unmatched by conventional surveying operations, which often use fixed installations and cannot flexibly adjust the installation position of the monitoring device according to changes in acquisition conditions. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: the fixed structure that uses bolts to press down allows the mounting base to be installed and fixed first after the installation position is selected. After the installation is completed, the upper base is then installed and connected to the wiring, which improves the ease of installation of the device. At the same time, if the installation position needs to be changed, the bolts can be directly removed to move the entire structure without rewiring, which improves the installation flexibility of the device.

Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0028] Reference Figures 1 to 3 This embodiment provides a connection structure and dam monitoring device, including a fixing unit 10, a lower pressure seat 11 inside the fixing unit 10, a welding groove 12 on the upper surface of the fixing unit 10, a wire seat 13 disposed in the welding groove 12, a wire integrated socket 15 disposed in the wire seat 13, the wire seat 13 and the wire integrated socket 15 being electrically connected, a mounting base 20 with its lower end disposed on the fixing unit 10, a receiver 23 disposed at the upper end of the mounting base 20, and a lightning rod 24 disposed on one side of the mounting base 20. By moving the lower pressure seat 11, the internal fixing can be driven to connect and fix the base to the lower wire integrated socket 15, reducing the loosening of internal wiring connections due to loosening of mounting bolts. The lightning rod 24 can better protect the receiver 23 from lightning strikes in the field and better protect the device body.

[0029] refer to Figure 2 and Figure 3In one embodiment provided in this application, the lower end of the pressure seat 11 is provided with two symmetrical trigger heads 111. The end of the pressure seat 11 near the trigger heads 111 is provided with two sets of elastic members 112. The wire integrated socket 15 is provided with a connecting contact head 151. The connecting end of the connecting contact head 151 is electrically connected to the connecting end of the wire seat 13. The wire integrated socket 15 is provided with a positioning groove 152. The wire seat 13 is provided with a clamping clamp 16 corresponding to the position of the positioning groove 152. One end of the clamping clamp 16 is provided with a linkage seat 161. The linkage seat 161 is provided with a reset member 162. The structure of the linkage seat 161 is the same as that of the trigger head 111. The trigger head 111 and the linkage seat 161 are provided with contact slopes with the same inclination angle. By using the clamping clamp 16 made of rubber material, the internal connection sealing can be increased while fixing, reducing the interference of external medium on the wiring position and improving the use effect of the device. By fixing the pressure seat 11 with bolts, the stability after installation is increased.

[0030] refer to Figure 1 An electrical control box 21 is installed on the mounting base 20, and a photovoltaic panel 22 is installed on the electrical control box 21. The electrical control box 21 is electrically connected to the receiver 23, and the photovoltaic panel 22 is electrically connected to the electrical control box 21. A grounding wire 25 is installed at the lower end of the lightning rod 24. A terminal block 26 is installed between the grounding wire 25 and the mounting base 20, and a wiring connector 27 is installed on the terminal block 26. By connecting the grounding wire 25 of the lightning rod 24 to the mounting base 20 which is wrapped with insulating material, the impact of lightning on the device body can be reduced, and the protection effect of the device during use can be improved.

[0031] In use, first connect the wire integrated socket 15 to the ground wire and pre-embed and fix it. Install the fixing unit 10 to the wire integrated socket 15 on the ground, position and connect it, and test whether the signal of the signal wire 14 is connected through the monitoring device. After completion, fix the fixing unit 10 with bolts. When the bolt moves downward, the lower pressure seat 11 will also move downward synchronously, driving the trigger head 111 to move downward, so that it contacts the linkage seat 161. This causes the clamping clamp 16 at the other end of the linkage seat 161 to contact the positioning groove 152, fixing and clamping the wire integrated socket 15. Then, position the mounting base 20 through the welding groove 12. First, connect the wires inside the mounting base 20 to the signal wire 14 and test it. Then, adjust the position of the wiring connector 27 according to the direction of the grounding grid, weld the wiring connector 27 to the grounding grid, and weld and fix the mounting base 20 at the same time. After completion, the device is put into use.

[0032] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
