Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment one

[0025] Referring to Figures 1-4 A fixed inclinometer for monitoring the foundation settlement of a water conservancy building, comprising an inclinometer body 1 and a connecting plate 2, a fixed bolt 3 is arranged below the connecting plate 2, a clamping groove 9 is formed in the side wall of the fixed bolt 3, a mounting box 5 is arranged on the top surface of the connecting plate 2, a threaded rod 7 is threadedly connected to the middle position of the top surface of the mounting box 5, a pull plate 10 is arranged below the threaded rod 7, a slide rod 12 is arranged on one side of the pull plate 10, a clamping block 11 is fixedly connected to one end of the slide rod 12, and a return spring 13 is connected between the clamping block 11 and the side wall of the pull plate 10.

[0026] Further, referring to Figure 4 Two through grooves are formed in the top surface of the connecting plate 2, and the fixed bolt 3 is slidably arranged in the through grooves. By arranging the through grooves and the fixed bolt 3 slidably arranged in the through grooves, the fixed bolt 3 can move up and down along the through grooves formed in the top surface of the connecting plate 2, which can be suitable for different steel cables and can also maintain stability.

[0027] The clamping block 11 is matched with the clamping groove 9, and the outer wall of the side of the clamping block 11 close to the clamping groove 9 is inclined. By matching the clamping block 11 with the clamping groove 9, the clamping block 11 and the clamping groove 9 can be clamped together, and by arranging the outer wall of the side of the clamping block 11 close to the clamping groove 9 to be inclined, the clamping block 11 can move more smoothly during the upward pushing of the fixed bolt 3.

[0028] Further, referring to Figures 3-4, the outer wall of the pull plate 10 is provided with a circular slot on both sides, and the sliding rod 12 is slidably arranged in the circular slot. By arranging the circular slot and the sliding rod 12 slidably arranged in the circular slot, when the clamping block 11 is resisted by the fixing bolt 3, the sliding rod 12 can retract into the pull plate 10, so that the clamping block 11 can be smoothly clamped in the clamping groove 9. Since the clamping block 11 is triangular, it will not easily come off after being clamped in the clamping groove 9.

[0029] The top surface of the pull plate 10 is fixedly provided with a guide rod 8. The specific number of the guide rod 8 is two, and the two guide rods 8 are symmetrically arranged and slidably arranged in the installation box 5. The top surface of the pull plate 10 is rotatably connected with a threaded rod 7.

[0030] By arranging the guide rod 8 and slidably arranging the guide rod 8 in the installation box 5, and finally rotatably connecting the threaded rod 7 with the top surface of the pull plate 10, the threaded rod 7 cannot rotate with the pull plate 10 after rotating, but can only rise synchronously.

[0031] In specific implementation, when the user needs to quickly connect the inclinometer body 1 with the steel cable, the user can place the steel cable in the groove above the fixing bolt 3, then insert the fixing bolt 3 into the through slot on the bottom surface of the connecting plate 2, and continuously apply force until the clamping block 11 is clamped into the clamping groove 9. At this time, the user can rotate the threaded rod 7. The threaded rod 7 will move the pull plate 10 upward after rotating. The fixing bolt 3 can be moved by the pull plate 10 due to the clamping of the clamping block 11 in the clamping groove 9. Therefore, the fixing bolt 3 will move synchronously after the pull plate 10 moves upward, so that the steel cable can be fixed below the connecting plate 2 by the fixing bolt 3.

[0032] By arranging the fixing bolt 3 and slidably arranging the clamping block 11 and the pull plate 10 in the installation box 5, and threadedly connecting the threaded rod 7 with the top surface of the installation box 5, the user only needs to place the steel cable above the fixing bolt 3 when connecting the inclinometer body 1 with the steel cable, then insert the fixing bolt 3 into the installation box 5, and finally rotate the threaded rod 7 to complete the connection of the inclinometer body 1 with the steel cable. Compared with the prior art, the fixing rate is improved, and the workload of the construction personnel is reduced.

[0033] In addition, after the fixing is completed, the fixed position may not be accurate, and at this time, the position of the inclinometer body 1 needs to be adjusted.

[0034] In the utility model, the installation box 5 is rotatably arranged on the top surface of the connecting plate 2. The side wall of the installation box 5 is provided with a limiting hole 16. The top surface of the connecting plate 2 is fixedly provided with a mounting plate 14. The mounting plate 14 is internally provided with a slidable limiting pin 15. The limiting pin 15 is matched with the limiting hole 16.

[0035] It should be noted that the limit pin 15 is provided with a plug and a limit disc, the limit disc is arranged at one end away from the mounting box 5, and the side wall of the limit disc is fixedly connected with the side wall of the mounting plate 14 through a tension spring 17.

[0036] The presence of these components makes it possible to directly pull the limit pin 15 out of the limit hole 16 when the position of the clinometer body 1 needs to be adjusted, so that the mounting box 5 can be rotated, and the mounting box 5 will drive the two guide rods 8 to rotate after being rotated, and the guide rods 8 are fixedly installed above the pull plate 10, so that the mounting box 5 will drive the pull plate 10 and the clamping block 11 to rotate, and the clamping block 11 will be separated from the inside of the clamping groove 9 after the pull plate 10 and the clamping block 11 are rotated, at this time the user can directly pull out the fixing bolt 3 to adjust the position of the clinometer body 1.

[0037] When it is necessary to fix again, only need to rotate the mounting box 5 to the initial position, and then insert the limit pin 15 into the limit hole 16, so that the position of the clinometer body 1 can be fixed again.

[0038] By not setting the limit pin 15 and the limit hole 16, and setting the mounting box 5 to be rotatable and mounted on the top surface of the clinometer body 1, the user can quickly complete the disassembly of the fixing bolt 3, so that the user can more conveniently adjust the position of the clinometer body 1.

[0039] The top surface of the threaded rod 7 is fixedly installed with a knob 6, the presence of the knob 6 makes the rotation of the threaded rod 7 more simple, and the bottom surface of the connecting plate 2 is fixedly installed with two retaining frames 4, and the presence of the retaining frames 4 makes the fixation of the steel cable more stable.

[0040] Working principle: when the user needs to quickly connect the clinometer body 1 with the steel cable, the user can place the steel cable in the groove above the fixing bolt 3, then insert the fixing bolt 3 into the through groove opened on the bottom surface of the connecting plate 2, and continuously apply force until the clamping block 11 is clamped into the clamping groove 9, at this time the user can rotate the threaded rod 7, the threaded rod 7 will drive the pull plate 10 to move upward after being rotated, and the fixing bolt 3 can be driven to move by the pull plate 10 through the clamping of the clamping groove 9 and the clamping block 11, so that the fixing bolt 3 will also move synchronously after the pull plate 10 moves upward, so that the steel cable can be fixed below the connecting plate 2 by the fixing bolt 3.

[0041] By setting the fixing bolt 3, and setting the clamping block 11 and the pull plate 10 in the mounting box 5, and screwing the threaded rod 7 on the top surface of the mounting box 5, the user only needs to place the steel cable above the fixing bolt 3 when connecting the clinometer body 1 with the steel cable, then insert the fixing bolt 3 into the inside of the mounting box 5, and finally rotate the threaded rod 7 to complete the connection of the clinometer body 1 with the steel cable, compared with the prior art, the fixing rate is improved, and the workload of the construction personnel is reduced.

[0042] When the position of the clinometer body 1 needs to be adjusted, the limiting pin 15 can be directly pulled out of the limiting hole 16, so that the mounting box 5 can be rotated. After the mounting box 5 is rotated, the two guide rods 8 are also rotated. The guide rods 8 are fixedly installed above the pull plate 10, so the mounting box 5 drives the pull plate 10 and the clamping block 11 to rotate. After the pull plate 10 and the clamping block 11 are rotated, the clamping block 11 is separated from the clamping groove 9. At this time, the user can directly pull out the fixing bolt 3 to adjust the position of the clinometer body 1.

[0043] When the position of the clinometer body 1 needs to be adjusted, the limiting pin 15 can be directly pulled out of the limiting hole 16, so that the mounting box 5 can be rotated. After the mounting box 5 is rotated, the two guide rods 8 are also rotated. The guide rods 8 are fixedly installed above the pull plate 10, so the mounting box 5 drives the pull plate 10 and the clamping block 11 to rotate. After the pull plate 10 and the clamping block 11 are rotated, the clamping block 11 is separated from the clamping groove 9. At this time, the user can directly pull out the fixing bolt 3 to adjust the position of the clinometer body 1.

[0044] By setting the fixing bolt 3, the clamping block 11 and the pull plate 10 are threadedly connected with the threaded rod 7 on the top surface of the mounting box 5, when the clinometer body 1 is connected with the steel cable, the user only needs to place the steel cable above the fixing bolt 3, then insert the fixing bolt 3 into the inside of the mounting box 5, and finally rotate the threaded rod 7 to complete the connection of the clinometer body 1 and the steel cable. Compared with the prior art, the fixing rate is improved, and the workload of the construction personnel is reduced.

[0045] By not setting the limiting pin 15 and the limiting hole 16, and setting the mounting box 5 to be rotatable and mounted on the top surface of the clinometer body 1, the user can quickly disassemble the fixing bolt 3, so that the user can more conveniently adjust the position of the clinometer body 1.
